25,The Introvert Owner’s Manual,"Nobody realizes that some people expend tremendous energy merely to be normal.
Albert Camus


“Whatever you plan, just make sure there are lots of people there,” said my husband in the run-up to his birthday last year. A few months later, before my own birthday, I uttered, “Whatever you plan, just make sure it is only me and you.”

I am an introvert. It is very likely some of you are too, or that you live, work or fraternise with one. Despite there being quite a few of us out there – some say as many as one third of the population, others as little as ten per cent – I think our professional and social lives are biased towards a definition of normality that is more accepting of the extrovert. I hope that by reading this article you will gain some insight to what goes on inside the head of the introvert(s) that you know and understand how to relate to them in a way that respects their disposition.

Before we go any further, I should define what exactly being an introvert means, and, equally important, what it does not. Only once this is established will you be able to handle your introvert correctly.

What defines an introvert

The simplest and most accurate way of describing an introvert is that she uses up energy in social situations and needs to be in solitude to recharge.

To explain what I mean, let us take the example of the The Sims: when you create a Sim, you can choose (among other characteristics) whether it will be outgoing or not. If the Sim is outgoing, when you play the game you need to make sure it interacts as much as possible with other Sims or its mood indicator (the plumbob) will become red and that is a bad thing. Conversely, if your Sim is not outgoing, when you put it in too many social situations its plumbob will become red too.

So your (real life) introvert might think you are great (you might even be her best friend, her spouse or her child), but if her plumbob is red, or nearly, she might just need a little time and space to recharge before she is ready to interact.

This is not the same thing as being shy or in a bad mood all the time. We are not necessarily awkward in social situations, but, if we have not had the time to recharge, being social might be almost impossible. This explains why your introvert will likely ask who will be at the gathering you have planned, for how long she will have to stay there, and what she will be doing before and after the event. It is the equivalent of you wanting to know if there will be power sockets in the restaurant to charge your iPhone – asking this does not mean you don’t want to attend.

The explanation above might be a simplistic way of looking at things, but I would say it is one that introverts can relate to; call it a minimalist approach to socialisation.

Caring for your introvert

Articles and conversations about introversion usually focus on how to fix the condition and how to make introverts more outgoing: a clear example of our society’s bias towards the normality of extroversion. Avoid this. You will not be able to convert your introvert into an extrovert. Believe it or not, there is nothing wrong with her.

In her 2012 TED talk, “The power of introverts”, Susan Cain pointed to the fact that places like school and work are designed for extroverts: students and workers are required to constantly work in groups and speaking up is highly valued. Both types are evaluated against the same criteria and more often than not people are expected to excel at being outspoken to be considered well rounded.

Obviously, this is not the right way to appraise your introvert. Comparing your introvert with an extrovert using the same parameters and simply asking her to behave more like an extrovert is a mistake and something that will only perpetuate an introvert’s idea that the problem lies with her.

Speaking up

Your introvert is likely to have strong opinions and ideas, and to have been listening to other people speak at meetings and workshops. Help her voice those thoughts by creating an environment where everyone stops and listens when someone speaks instead of one which fosters interruptions. Show her that it is acceptable for someone to take time to think before they speak: silences are OK. Allow her the freedom to be herself instead of pressuring her to change an innate quality.

It is not uncommon to find an introvert who likes to express ideas in writing. The world of web professionals excels in the spread of knowledge that is shared and sought through the written word. Give your introvert the necessary time and tools to write about the job, if she is that way inclined; this might be a good alternative to asking her to speak out.

Group work

I remember the sinking feeling whenever I heard my teachers say the dreaded words: “And now you’re going to break out into groups of…” Being an introvert does not mean you do not like people (or like to be around or work with others). It is just that activities such as group work will invariably drain your introvert’s energy rapidly. Your introvert’s batteries will need to be fully charged for her to be at her best and afterwards she will most likely need to recharge.

Quiet time

These days, one of the things that I value most at work is the ability to have moments to create and to think in solitude. When I am able to have those moments at the right time I will in turn be happy to participate in group conversations and tasks. Allow your introvert to have those moments: this does not mean she will have to work from home one day a week (but maybe it will); it might simply mean allowing her to take her laptop and her notebook and work from the empty side of the office, or from the coffee shop downstairs for an hour or two. In all likelihood she will come back fully recharged and ready to engage in more social activities – her plumbob will again be bright green.

Leadership

Do not think that your introvert cannot lead. Cain notes that introverted leaders are more likely to let their proactive employees run with their ideas instead of taking the ideas as their own. I would say that is a positive attribute in a leader. Maybe next time a project starts, talk to your introvert about the possibility of her being in a leadership position or of having more responsibility: you might be surprised at her ability to plan and foresee potential obstacles in the project.

Final thoughts

You would not tell someone with dyslexia to get better at spelling without giving her the right tools and enough time to do so. Equally, do not ask your introvert to be more outgoing, or to turn her frown upside down, without giving her the space to do so.

I believe that everyone is an introvert at some point. Everyone needs a moment of solitude now and then, and the work we do requires frequent periods of deep focus and concentration. Striving to create workplaces, classrooms, homes that allow introverts to shine and be comfortable in their skin has the potential to also make those places more balanced for everyone else.

44,Taglines and Truisms,"To bring her good luck, “white rabbits” was the first thing that my grandmother said out loud on the first day of every month. We all need a little luck, but we shouldn’t rely on it, especially when it comes to attracting new clients.

The first thing we say to a prospective client when they visit our website for the first time helps them to understand not only what we do but why we do it. We can also help them understand why they should choose to work with us over one of our competitors.

Take a minute or two to look at your competitors’ websites. What’s the first thing that they say about themselves? Do they say that they “design delightful digital experiences,” “craft beautiful experiences” or “create remarkable digital experiences?”

It’s easy to find companies who introduce themselves with what they do, their proposition, but what a company does is only part of their story. Their beliefs and values, what they stand for why they do what they do are also important. 

When someone visits our websites for the first time, we have only a brief moment to help them understand us. To help us we can learn from the advertising industry, where the job of a tagline is to communicate a concept, deliver a message and sell a product, often using only a few words.

When an advertising campaign is effective, its tagline stays with you, sometimes long after that campaign is over. For example, can you remember which company or brand these taglines help to sell? (Answers at the bottom of the article:)


The Ultimate Driving Machine
Just Do It
Don’t Leave Home Without It


A clever tagline isn’t just a play on words, although it can include one. A tagline does far more than help make your company memorable. Used well, it brings together notions of what makes your company and what you offer special. Then it expresses those notions in a few words or possibly a short sentence. 

I’m sure that everyone can find examples of company slogans written in the type of language that should stay within the walls of a marketing department. We can also find taglines where the meaning is buried so deep that the tag itself becomes effectively meaningless.

A meaningful tagline supports our ideas about who we are and what we offer, and provides a platform for different executions of them, sometimes over a period of time. For a tagline to work well, it must allow for current and future ideas about a brand.

It must also be meaningful to our brand and describe a truism, a truth that need not be a fact or statistic, but something that’s true about us, who we are, what we do and why that’s distinctive. It can be obvious, funny, serious or specific but above all it must be true. It should also be difficult to argue with, making your messages difficult to argue with too.

I doubt that I need remind you who this tagline belongs to:


	There are some things money can’t buy. For everything else there’s MasterCard.


That tagline was launched in 1997 by McCann-Erickson along with the “Priceless” campaign and it helped establish MasterCard as a friendlier credit card company, one with a sense of humour. 

MasterCard’s truism is that the things which really matter in life can’t be bought. They are worth more than anything that a monetary value can be applied to. In expressing that truism through the tagline, MasterCard’s advertising tells people to use not just any credit card, but their MasterCard, to pay for everything they buy.

“Guinness is good for you” may have been a stretch, but “Good things come to those who wait” builds on the truism that patience is a virtue and therefore a good pint of Guinness takes time to pour (119.5 seconds. I know you were wondering.)

The fact that British Airways flies to more destinations than any other airline is their truism, and led their advertisers to the now famous tagline, “The world’s favourite airline.”



At my company, Stuff & Nonsense, we’ve been thinking about taglines as we think about our position within an industry that seems full of companies who “design”, “craft”, and “create” “delightful”, “beautiful”, “remarkable digital experiences”.

Much of what made us different has changed along with the type of work we’re interested in doing. Our work’s expanded beyond websites and now includes design for mobile and other media. It’s true we can’t know how or where it will be seen. The ways that we make it are flexible too as we’re careful not to become tied to particular tools or approaches. 

It’s also true that we’re a small team. One that’s flexible enough to travel around the world to work alongside our clients. We join their in-house teams and we collaborate with them in ways that other agencies often find more difficult. We know that our clients appreciate our flexibility and have derived enormous value from it. We know that we’ve won business because of it and that it’s now a big part of our proposition.

Our truism is that we’re flexible, “Fabulously flexible” as our tagline now expresses. And although we know that there may be other agencies who can be similarly flexible – after all, being flexible is not a unique selling proposition – only we do it so fabulously.



As the old year rolls into the new, how will your company describe what you do in 2015? More importantly, how will you tell prospective clients why you do it, what matters to you and why they should work with you?

Start by writing a list of truisms about your company. Write as many as you can, but then whittle that list down to just one, the most important truth. Work on that truism to create a tagline that’s meaningful, difficult to be argue with and, above all, uniquely yours.

35,SEO in 2015 (and Why You Should Care),"If your business is healthy, you can always find plenty of reasons to leave SEO on your to-do list in perpetuity. After all, SEO is technical, complicated, time-consuming and potentially dangerous. The SEO industry is full of self-proclaimed gurus whose lack of knowledge can be deadly. There’s the terrifying fact that even if you dabble in SEO in the most gentle and innocent way, you might actually end up in a worse state than you were to begin with.

To make matters worse, Google keeps changing the rules. There have been a bewildering number of major updates, which despite their cuddly names have had a horrific impact on website owners worldwide.

Fear aside, there’s also the issue of time. It’s probably tricky enough to find the time to read this article. Setting up, planning and executing an SEO campaign might well seem like an insurmountable obstacle.

So why should you care enough about SEO to do it anyway?

The main reason is that you probably already see between 30% and 60% of your website traffic come from the search engines. That might make you think that you don’t need to bother, because you’re already doing so well. But you’re almost certainly wrong.

If you have a look through the keyword data in your Google Webmaster Tools account, you’ll probably see that around 30–50% of the keywords used to find your website are brand names – the names of your products or companies. These are searches carried out by people who already know about you. But the people who don’t know who you are but are searching for what you sell aren’t finding you right now. This is your opportunity.

If a person goes looking for a company or product by name, Google will steer them towards what they’re looking for. Their intelligence does have limits, however, and even though they know your name they won’t be completely clear about what you sell. That’s where SEO would come in.

Still need more convincing? How about the fact that the seeming complexities of SEO mean that your competition are almost certainly neglecting it too. They have the same reservations as you about complexity, time and danger, and hopefully they aren’t reading this article and so are none the wiser of the well-kept secret: that 70% of SEO is easy.

I’m going to lead you through what you need to do to tap into that stream of people looking for what you sell right now.

What is real SEO?

Real SEO is all about helping Google understand the content of your website. It’s about steering, guiding and assisting Google. Not manipulating it.

It’s easy to assume that Google already understands the content and relevance of each and every page on your website, but the fact is that it needs a fair amount of hand-holding. Fortunately, helping Google along really isn’t very difficult at all.

Rest assured that real SEO has nothing to do with keyword stuffing, keyword density, hacks, tricks or cunning techniques. If you hear any of these terms from your SEO advisor, run away from them as quickly as you can.

Understanding your current situation – Google Analytics

Before you can do anything to improve your SEO status, you need to get an idea of how you’re already doing. Below is a very quick and easy way of doing so.

1. Open up your Google Analytics account.

2. Click on the date range selector on the top-right of the interface and change the year of the first date to last year. So 12 Dec 2014 will become 12 Dec 2013. Then click on Apply.

3. Click on the All Sessions rectangle towards the top-left, click once on Organic Traffic and click Apply.

4. Click the little black-and-white squares icon that has now appeared under the date selector on the top-right, and drag the slider all the way over to Higher Precision.

5. Change the interval buttons on the top-right of the graph to Week to make this easier to digest.

At this point your graph should look something like this:



It’s worth noting the approximate proportion of your visitors that currently come from organic sources.

6. Click the little downwards arrow to the right of the All Sessions rectangle and choose Remove, so that we’re only looking at the organic traffic on its own.

7. Click on Select a metric next to the Sessions button above the graph and select Pages / Session. You should then see something like this:



In the example above we can see that the quantity of traffic has been increasing since the middle of August, but the quality of the traffic (as measured by the number of pages per session) has fallen significantly. 

How you choose to view this is down to your own graph, recent history and interpretation of events, but this should give you an indication of how things stand at the present time. Trends are often much more revealing than a snapshot of a brief moment in time.

Your Google Webmaster Tools data

If you’re not very familiar with your Google Webmaster Tools account, it’s really worth taking ten to fifteen minutes to see what’s on offer. I can’t recommend this enough. From the point of view of an SEO health check, I’d advise you to look into the HTML Improvements, Crawl Errors and Crawl Stats, and most importantly the Search Queries.

From what you see here and the trends shown in your Analytics data, you should now have a good idea of your current status. If you want to explore further, I recommend Screaming Frog as a good diagnostics tool, or Botify if your website is large or unusually complex.

Combining the data into something useful

Your Google Analytics session will have shown you how you’re doing from an SEO point of view in terms of the quantity and, to some extent, the quality of your visitors. But it’s only showing you what is already working. In other words: the people who are finding you on the search engines, and clicking on your links.

The Google Webmaster Tools search query data, on the other hand, will give you a better idea of what isn’t working. It will show you the keyword searches that are getting you listed in the results, but which aren’t necessarily getting clicked. And it doesn’t take much by the way of expertise to see why.

For example, if you see your targeted keyword, which you feel is extremely relevant, has generated over 2,000 impressions in the last month but produced only two clicks, you’ll probably find a very low average position. Bear in mind that an average position of fourteen will mean being around halfway down the second page of results. Think about how rarely you go beyond the first two or three listings, never mind to the second page of results, and you’ll understand why the click-through rate is so low.

So now you have an idea of what you’re being found for at the present time. But what about the other terms?

What would you like to be found for?

This is one of the more common SEO mistakes, on a number of different levels. 

Many businesses assume that they don’t need to worry about keyword research. They think they know what terms people use to find what they sell, and they also assume that Google understands the content on their website. This is incorrect on all counts.

A better starting point is to brainstorm a small number of your most obvious keywords, then run them through Google’s Keyword Planner. Ignore the information in the Ad group ideas tab, and instead go straight to the Keyword ideas tab. Rather than wade through the very unfriendly interface, I recommend downloading the data as a spreadsheet, in which not only is more detail included, but you can also slice, dice, sort and report the data as required.

From there you can delete all the irrelevant columns, and start working your way through the list, deleting any irrelevant keywords as you go along.

It’s around this stage that you may hit a problem in terms of where to focus your efforts. The number of reported searches for a given keyword is of course important, but so is the level of competition. Ideally, you’d like keywords with plenty of searches but not too much competition.

I personally like to factor both together by adding a column that simply divides the number of searches squared by the level of competition:

(number of searches × number of searches) ÷ competition

There are plenty of alternatives to this basic formula, but I like it for ease of use and simplicity. Once I’ve added this column, I then sort the data by this value (largest to smallest) and I then only usually need ten to fifteen keywords at most to give me plenty of ideas to work with.

This is a slightly involved but effective methodology for keyword research, as what you’re left with is a list of keywords that both Google and you consider to be relevant to the content of your website. And relevance is an important concept in SEO.

Real SEO keyword research is about making sure that your customers, website and Google are all in agreement and alignment over the content of your website. Other sources of inspiration and ideas include having a look at what terms your competition are targeting, Google Trends and, of course, Google Suggest. If you’re not sure where to find these things, you can probably work out where to search for them!

If you want to dive further into understanding your current search engine status, search for some of the better keywords that you just discovered and see where you rank compared to your competition. Note that it’s vital to avoid Google serving up personalised results, so either use the privacy, incognito or anonymous mode of your browser for the searches, or use a browser that you don’t normally use. I hope this is Internet Explorer. If what you find isn’t great, don’t despair: everything in SEO is fixable (terms and conditions may apply).

Putting it all together

You should now have a good idea of where things stand with your current search engine traffic, and a solid list of keywords that you’re not getting visitors for but very much want.

All that’s left now is to work out how to use these keywords. But before we do, let’s take a quick step back.

If you have in any way kept up with what’s been happening in SEO over the last couple of years, you’ll have probably heard about Google updates with names like Panda, Hummingbird, Phantom, Pirate and more.

I won’t go into the technical details of what Google is doing, but it is important to understand why they’re trying to do it. At the most basic level, Google understands that there’s a very real problem with people who are trying manipulate its index. In response to this, Google is trying to clean up its results. They don’t want people getting fed up with bad results and considering other options – have you even tried Bing?

This is extremely important. Remember earlier when I said that 70% of SEO was easy? That rule still applies. So, for example, if you have a list of keywords that you know are relevant to what you sell, then all you need to do is create great content for them. Incredibly, that’s all there is to it (terms and conditions apply again, unfortunately – see below).

There is, however, one simple rule to be consistently followed without exception: that the content you create should not only be good quality and completely original, but it should also be written primarily for the human visitor and not the search engine spider.

In other words, if you create some fantastic content for a keyword like “choosing a small business HR service”, then the article should not only make perfect sense if read out loud (as opposed to the same phrase being repeated fifteen times), but also provide real value to the person reading it.

So the process is simple:


	Choose your keywords
	Create spectacular content


Wait. Is it really that simple?

Unfortunately there’s a lot more to the other 30% of SEO than just creating great content and waiting for the visitors. There are issues like helping Google understand the content on your pages and website, incoming links, page authority, domain authority, usage patterns, spam factors, canonical issues and much more.

But there’s the often overlooked fact about Google: it actually does a reasonable job of working out what’s on your website and (to some extent) understanding the gist of it. If you’ve never done any SEO on your website but still get some traffic from Google, this is why.

Even without dabbling in the other 30% of SEO, by creating the right content for the right visitors using the precise language and terminology that your potential customers are using, you’re significantly better off than your competition. And you can only gain from this.

When you’ve checked this off your to-do list and made it an ingrained part of your content creation process, then you’re ready to delve into the other 30% of SEO. The not-so-easy side.

Until then, work on understanding your current situation, exploring the opportunities, creating a list of good keywords, creating the right content for them, and starting 2015 with a little bit of smart, safe and real SEO.",2014,Dave Collins,davecollins,2014-12-15T00:00:00+00:00,https://24ways.org/2014/seo-in-2015-and-why-you-should-care/,business
46,Responsive Enhancement,"24 ways has been going strong for ten years. That’s an aeon in internet timescales. Just think of all the changes we’ve seen in that time: the rise of Ajax, the explosion of mobile devices, the unrecognisably changed landscape of front-end tooling.

Tools and technologies come and go, but one thing has remained constant for me over the past decade: progressive enhancement.

Progressive enhancement isn’t a technology. It’s more like a way of thinking. Instead of thinking about the specifics of how a finished website might look, progressive enhancement encourages you to think about the fundamental meaning of what the website is providing. So instead of thinking of a website in terms of its ideal state in a modern browser on a nice widescreen device, progressive enhancement allows you to think about the core functionality in a more abstract way.

Once you’ve figured out what the core functionality is – adding an item to a shopping cart, posting a message, sharing a photo – then you can enable that functionality in the simplest possible way. That usually means starting with good old-fashioned HTML. Links and forms are often all you need. Then, once you have the core functionality working in a basic way, you can start to enhance to make a progressively better experience for more modern browsers.

The advantage of working this way isn’t just that your site will work in older browsers (albeit in a rudimentary way). It also ensures that if anything goes wrong in a modern browser, it won’t be catastrophic.

There’s a common misconception that progressive enhancement means that you’ll spend your time dealing with older browsers, but in fact the opposite is true. Putting the basic functionality into place doesn’t take very long at all. And once you’ve done that, you’re free to spend all your time experimenting with the latest and greatest browser technologies, secure in the knowledge that even if they aren’t universally supported yet, that’s OK: you’ve already got your fallback in place.

The key to thinking about web development this way is realising that there isn’t one final interface – there could be many, slightly different interfaces depending on the properties and capabilities of any particular user agent at any particular moment. And that’s OK. Websites do not need to look the same in every browser.

Once you truly accept that, it’s an immensely liberating idea. Instead of spending your time trying to make websites look the same in wildly varying browsers, you can spend your time making sure that the core functionality of what you build works everywhere, while providing the best possible experience for more capable browsers.

Allow me to demonstrate with a simple example: navigation.

Step one: core functionality

Let’s say we have a straightforward website about the twelve days of Christmas, with a page for each day. The core functionality is pretty clear:


	To read about any particular day.
	To browse from day to day.


The first is easily satisfied by marking up the text with headings, paragraphs and all the usual structural HTML elements. The second is satisfied by providing a list of good ol’ hyperlinks.

Now where’s the best place to position this navigation list? Personally, I’m a big fan of the jump-to-footer pattern. This puts the content first and the navigation second. At the top of the page there’s a link with an href attribute pointing to the fragment identifier for the navigation.

<body>
  <main role=""main"" id=""top"">
    <a href=""#menu"" class=""control"">Menu</a>
    ...
  </main>
  <nav role=""navigation"" id=""menu"">
    ...
    <a href=""#top"" class=""control"">Dismiss</a>
  </nav>
</body>

See the footer-anchor pattern in action.

Because it’s nothing more than a hyperlink, this works in just about every browser since the dawn of the web. Following hyperlinks is what web browsers were made to do (hence the name).

Step two: layout as an enhancement

The footer-anchor pattern is a particularly neat solution on small-screen devices, like mobile phones. Once more screen real estate is available, I can use the magic of CSS to reposition the navigation above the content. I could use position: absolute, flexbox or, in this case, display: table.

@media all and (min-width: 35em) {
  .control {
    display: none;
  }
  body {
    display: table;
  }
  [role=""navigation""] {
    display: table-caption;
    columns: 6 15em;
  }
}

See the styles for wider screens in action

Step three: enhance!

Right. At this point I’m providing core functionality to everyone, and I’ve got nice responsive styles for wider screens. I could stop here, but the real advantage of progressive enhancement is that I don’t have to. From here on, I can go crazy adding all sorts of fancy enhancements for modern browsers, without having to worry about providing a fallback for older browsers – the fallback is already in place.

What I’d really like is to provide a swish off-canvas pattern for small-screen devices. Here’s my plan:


	Position the navigation under the main content.
	Listen out for the .control links being activated and intercept that action.
	When those links are activated, toggle a class of .active on the body.
	If the .active class exists, slide the content out to reveal the navigation.


Here’s the CSS for positioning the content and navigation:

@media all and (max-width: 35em) {
  [role=""main""] {
    transition: all .25s;
    width: 100%;
    position: absolute;
    z-index: 2;
    top: 0;
    right: 0;
  }
  [role=""navigation""] {
    width: 75%;
    position: absolute;
    z-index: 1;
    top: 0;
    right: 0;
  }
  .active [role=""main""] {
    transform: translateX(-75%);
  }
}

In my JavaScript, I’m going to listen out for any clicks on the .control links and toggle the .active class on the body accordingly:

(function (win, doc) {
  'use strict';
  var linkclass = 'control',
    activeclass = 'active',
    toggleClassName = function (element, toggleClass) {
      var reg = new RegExp('(s|^)' + toggleClass + '(s|$)');
      if (!element.className.match(reg)) {
        element.className += ' ' + toggleClass;
      } else {
        element.className = element.className.replace(reg, '');
      }
    },
    navListener = function (ev) {
      ev = ev || win.event;
      var target = ev.target || ev.srcElement;
      if (target.className.indexOf(linkclass) !== -1) {
        ev.preventDefault();
        toggleClassName(doc.body, activeclass);
      }
    };
  doc.addEventListener('click', navListener, false);
}(this, this.document));

I’m all set, right? Not so fast!

Cutting the mustard

I’ve made the assumption that addEventListener will be available in my JavaScript. That isn’t a safe assumption. That’s because JavaScript – unlike HTML or CSS – isn’t fault-tolerant. If you use an HTML element or attribute that a browser doesn’t understand, or if you use a CSS selector, property or value that a browser doesn’t understand, it’s no big deal. The browser will just ignore what it doesn’t understand: it won’t throw an error, and it won’t stop parsing the file.

JavaScript is different. If you make an error in your JavaScript, or use a JavaScript method or property that a browser doesn’t recognise, that browser will throw an error, and it will stop parsing the file. That’s why it’s important to test for features before using them in JavaScript. That’s also why it isn’t safe to rely on JavaScript for core functionality.

In my case, I need to test for the existence of addEventListener:

(function (win, doc) {
  if (!win.addEventListener) {
    return;
  }
  ...
}(this, this.document));

The good folk over at the BBC call this kind of feature test cutting the mustard. If a browser passes the test, it cuts the mustard, and so it gets the enhancements. If a browser doesn’t cut the mustard, it doesn’t get the enhancements. And that’s fine because, remember, websites don’t need to look the same in every browser.

I want to make sure that my off-canvas styles are only going to apply to mustard-cutting browsers. I’m going to use JavaScript to add a class of .cutsthemustard to the document:

(function (win, doc) {
  if (!win.addEventListener) {
    return;
  }
  ...
  var enhanceclass = 'cutsthemustard';
  doc.documentElement.className += ' ' + enhanceclass;
}(this, this.document));

Now I can use the existence of that class name to adjust my CSS:

@media all and (max-width: 35em) {
  .cutsthemustard [role=""main""] {
    transition: all .25s;
    width: 100%;
    position: absolute;
    z-index: 2;
    top: 0;
    right: 0;
  }
  .cutsthemustard [role=""navigation""] {
    width: 75%;
    position: absolute;
    z-index: 1;
    top: 0;
    right: 0;
  }
  .cutsthemustard .active [role=""main""] {
    transform: translateX(-75%);
  }
}

See the enhanced mustard-cutting off-canvas navigation. Remember, this only applies to small screens so you might have to squish your browser window.

Enhance all the things!

This was a relatively simple example, but it illustrates the thinking behind progressive enhancement: once you’re providing the core functionality to everyone, you’re free to go crazy with all the latest enhancements for modern browsers.

Progressive enhancement doesn’t mean you have to provide all the same functionality to everyone – quite the opposite. That’s why it’s key to figure out early on what the core functionality is, and make sure that it can be provided with the most basic technology. But from that point on, you’re free to add many more features that aren’t mission-critical. You should reward more capable browsers by giving them more of those features, such as animation in CSS, geolocation in JavaScript, and new input types in HTML.

Like I said, progressive enhancement isn’t a technology. It’s a way of thinking. Once you start thinking this way, you’ll be prepared for whatever the next ten years throws at us.",2014,Jeremy Keith,jeremykeith,2014-12-09T00:00:00+00:00,https://24ways.org/2014/responsive-enhancement/,code
27,Putting Design on the Map,"The web can leave us feeling quite detached from the real world. Every site we make is really just a set of abstract concepts manifested as tools for communication and expression. At any minute, websites can disappear, overwritten by a newfangled version or simply gone. I think this is why so many of us have desires to create a product, write a book, or play with the internet of things. We need to keep in touch with the physical world and to prove (if only to ourselves) that we do make real things.

I could go on and on about preserving the web, the challenges of writing a book, or thoughts about how we can deal with the need to make real things. Instead, I’m going to explore something that gives us a direct relationship between a website and the physical world – maps.


	A map does not just chart, it unlocks and formulates meaning; it forms bridges between here and there, between disparate ideas that we did not know were previously connected.
Reif Larsen, The Selected Works of T.S. Spivet


The simplest form of map on a website tends to be used for showing where a place is and often directions on how to get to it. That’s an incredibly powerful tool. So why is it, then, that so many sites just plonk in a default Google Map and leave it as that? You wouldn’t just use dark grey Helvetica on every site, would you? Where’s the personality? Where’s the tailored experience? Where is the design?

Jumping into design

Let’s keep this simple – we all want to be better web folk, not cartographers. We don’t need to go into the history, mathematics or technology of map making (although all of those areas are really interesting to research). For the sake of our sanity, I’m going to gloss over some of the technical areas and focus on the practical concepts.

Tiles

If you’ve ever noticed a map loading in sections, it’s because it uses tiles that are downloaded individually instead of requiring the user to download everything that they might need. These tiles come in many styles and can be used for anything that covers large areas, such as base maps and data. You’ve seen examples of alternative base maps when you use Google Maps as Google provides both satellite imagery and road maps, both of which are forms of base maps. They are used to provide context for the real world, or any other world for that matter. A marker on a blank page is useless.

The tiles are representations of the physical; they do not have to be photographic imagery to provide context. This means you can design the map itself. The easiest way to conceive this is by comparing Google’s road maps with Ordnance Survey road maps. Everything about the two maps is different: the colours, the label fonts and the symbols used. Yet they still provide the exact same context (other maps may provide different context such as terrain contours).

 Comparison of Google Maps (top) and the Ordnance Survey (bottom).

Carefully designing the base map tiles is as important as any other part of the website. The most obvious, yet often overlooked, aspect are aesthetics and branding. Maps could fit in with the rest of the site; for example, by matching the colours and line weights, they can enhance the full design rather than inhibiting it. You’re also able to define the exact purpose of the map, so instead of showing everything you could specify which symbols or labels to show and hide.

I’ve not done any real research on the accessibility of base maps but, having looked at some of the available options, I think a focus on the typography of labels and the colour of the various elements is crucial. While you can choose to hide labels, quite often they provide the data required to make sense of the map. Therefore, make sure each zoom level is not too cluttered and shows enough to give context. Also be as careful when choosing the typeface as you are in any other design work. As for colour, you need to pay closer attention to issues like colour-blindness when using colour to convey information. Quite often a spectrum of colour will be used to show data, or to show the topography, so you need to be aware that some people struggle to see colour differences within a spectrum.

A nice example of a customised base map can be found on Michael K Owens’ check-in pages:

 One of Michael K Owens’ check-in pages.

As I’ve already mentioned, tiles are not just for base maps: they are also for data. In the screenshot below you can see how Plymouth Marine Laboratory uses tiles to show data with a spectrum of colour.

Technical

You’re probably wondering how to design the base layers. I will briefly explain the concepts here and give you tools to use at the end of the article. If you’re worried about the time it takes to design the maps, don’t be – you can automate most of it. You don’t need to manually draw each tile for the entire world!

We’ve learned the importance of web standards the hard way, so you’ll be glad (and I won’t have to explain the advantages) of the standard for web mapping from the Open Geospatial Consortium (OGC) called the Web Map Service (WMS). You can use conventional file formats for the imagery but you need a way to query for the particular tiles to show for the area and zoom level, that is what WMS does.

Features

Tiles are great for covering large areas but sometimes you need specific smaller areas. We call these features and they usually consist of polygons, lines or points. Examples include postcode boundaries and routes between places, or even something more dynamic such as borders of nations changing over time.

Showing features on a map presents interesting design challenges. If the colour or shape conveys some kind of data beyond geographical boundaries then it needs to be made obvious. This is actually really hard, without building complicated user interfaces. For example, in the image below, is it obvious that there is a relationship between the colours? Does it need a way of showing what the colours represent?

	Features are represented by means of lines or colors; and the effective use of lines or colors requires more than knowledge of the subject – it requires artistic judgement.
Erwin Josephus Raisz, cartographer (1893–1968)


Where lots of boundaries are small and close together (such as a high street or shopping centre) will it be obvious where the boundaries are and what they represent? When designing maps, the hardest challenge is dealing with how the data is represented and how it is understood by the user.

Technical

As you probably gathered, we use WMS for tiles and another standard called the web feature service (WFS) for specific features. I need to stress that the difference between the two is that WMS is for tiling, whereas WFS is for specific features. Both can use similar file formats but should be used for their particular use cases. You may be wondering why you can’t just use a vector format such as KML, GeoJSON (or even SVG) – and you can – but the issue is the same as for WMS: you need a way to query the data to get the correct area and zoom level.

User interface

There is of course never a correct way to design an interface as there are so many different factors to take into consideration for each individual project. Maps can be used in a variety of ways, to provide simple information about directions or for complex visualisations to explain large amounts of data. I would like to just touch on matters that need to be taken into account when working with maps.

As I mentioned at the beginning, there are so many Google Maps on the web that people seem to think that its UI is the only way you can use a map. To some degree we don’t want to change that, as people know how to use them; but does every map require a zoom slider or base map toggle? In fact, does the user need to zoom at all? The answer to that one is generally yes, zooming does provide more context to where the map is zoomed in on.

In some cases you will need to let users choose what goes on the map (such as data layers or directions), so how do they show and hide the data? Does a simple drop-down box work, or do you need search? Google’s base map toggle is quite nice since it doesn’t offer many options yet provides very different contexts and styling.

It isn’t until we get to this point that we realise just plonking a quick Google map is really quite ridiculous, especially when compared to the amount of effort we make in other areas such as colour, typography or how the CSS is written. Each of these is important but we need to make sure the whole site is designed, and that includes the maps as much as any other content.

Putting it into practice

I could ramble on for ages about what we can do to customise maps to fit a site’s personality and correctly represent the data. I wanted to focus on concepts and standards because tools constantly change and it is never good to just rely on a tool to do the work. That said, there are a large variety of tools that will help you turn these concepts into reality. This is not a comparison; I just want to show you a few of the many options you have for maps on the web.

Google

OK, I’ve been quite critical so far about Google Maps but that is only because there is such a large amount of the default maps across the web. You can style them almost as much as anything else. They may not allow you to use custom WMS layers but Google Maps does have its own version, called styled maps. Using an array of map features (in the sense of roads and lakes and landmarks rather than the kind WFS is used for), you can style the base map with JavaScript. It even lets you toggle visibility, which helps to avoid the issue of too much clutter on the map. As well as lacking WMS, it doesn’t support WFS, but it does support GeoJSON and KML so you can still show the features on the map. You should also check out Google Maps Engine (the new version of My Maps), which provides an interface for creating more advanced maps with a selection of different base maps. A premium version is available, essentially for creating map-based visualisations, and it provides a step up from the main Google Maps offering. A useful feature in some cases is that it gives you access to many datasets.

Leaflet

You have probably seen Leaflet before. It isn’t quite as popular as Google Maps but it is definitely used often and for good reason. Leaflet is a lightweight open source JavaScript library. It is not a service so you don’t have to worry about API throttling and longevity. It gives you two options for tiling, the ability to use WMS, or to directly get the file using variables in the filename such as /{z}/{x}/{y}.png. I would recommend using WMS over dynamic file names because it is a standard, but the ability to use variables in a file name could be useful in some situations. Leaflet has a strong community and a well-documented API.

Mapbox

As a freemium service, Mapbox may not be perfect for every use case but it’s definitely worth looking into. The service offers incredible customisation tools as well as lots of data sources and hosting for the maps. It also provides plenty of libraries for the various platforms, so you don’t have to only use the maps on the web.

Mapbox is a service, though its map design tool is open source. Mapbox Studio is a vector-only version of their previous tool called Tilemill. Earlier I wrote about how typography and colour are as important to maps as they are to the rest of a website; if you thought, “Yes, but how on earth can I design those parts of a map?” then this is the tool for you. It is incredibly easy to use. Essentially each map has a stylesheet.

If you do not want to open a paid-for Mapbox account, then you can export the tiles (as PNG, SVG etc.) to use with other map tools.

OpenLayers

After a long wait, OpenLayers 3 has been released. It is similar to Leaflet in that it is a library not a service, but it has a much broader scope. During the last year I worked on the GIS portal at Plymouth Marine Laboratory (which I used to show the data tiles earlier), it essentially used OpenLayers 2 to create a web-based geographic information system, taking a large amount of data and permitting analysis (such as graphs) without downloading entire datasets and complicated software. OpenLayers 3 has improved greatly on the previous version in both performance and accessibility. It is the ideal tool for complex map-based web apps, though it can be used for the simple use cases too.

OpenStreetMap

I couldn’t write an article about maps on the web without at least mentioning OpenStreetMap. It is the place to go for crowd-sourced data about any location, with complete road maps and a strong API.

ViziCities

The newest project on this list is ViziCities by Robin Hawkes and Peter Smart. It is a open source 3-D visualisation tool, currently in the very early stages of development. The basic example shows 3-D buildings around the world using OpenStreetMap data. Robin has used it to create some incredible demos such as real-time London underground trains, and planes landing at an airport. Edward Greer and I are currently working on using ViziCities to show ideal housing areas based on particular personas. We chose it because the 3-D aspect gives us interesting possibilities for the data we are able to visualise (such as bar charts on the actual map instead of in the UI). Despite not being a completely stable, fully featured system, ViziCities is worth taking a look at for some use cases and is definitely going to go from strength to strength.



So there you have it – a whistle-stop tour of how maps can be customised. Now please stop plonking in maps without thinking about it and design them as you design the rest of your content.",2014,Shane Hudson,shanehudson,2014-12-11T00:00:00+00:00,https://24ways.org/2014/putting-design-on-the-map/,design
36,Naming Things,"There are only two hard things in computer science: cache invalidation and naming things.
Phil Karlton


Being a professional web developer means taking responsibility for the code you write and ensuring it is comprehensible to others. Having a documented code style is one means of achieving this, although the size and type of project you’re working on will dictate the conventions used and how rigorously they are enforced.

Working in-house may mean working with multiple developers, perhaps in distributed teams, who are all committing changes – possibly to a significant codebase – at the same time. Left unchecked, this codebase can become unwieldy. Coding conventions ensure everyone can contribute, and help build a product that works as a coherent whole.

Even on smaller projects, perhaps working within an agency or by yourself, at some point the resulting product will need to be handed over to a third party. It’s sensible, therefore, to ensure that your code can be understood by those who’ll eventually take ownership of it.

Put simply, code is read more often than it is written or changed. A consistent and predictable naming scheme can make code easier for other developers to understand, improve and maintain, presumably leaving them free to worry about cache invalidation.

Let’s talk about semantics

Names not only allow us to identify objects, but they can also help us describe the objects being identified.

Semantics (the meaning or interpretation of words) is the cornerstone of standards-based web development. Using appropriate HTML elements allows us to create documents and applications that have implicit structural meaning. Thanks to HTML5, the vocabulary we can choose from has grown even larger.

HTML elements provide one level of meaning: a widely accepted description of a document’s underlying structure. It’s only with the mutual agreement of browser vendors and developers that <p> indicates a paragraph.

Yet (with the exception of widely accepted microdata and microformat schemas) only HTML elements convey any meaning that can be parsed consistently by user agents. While using semantic values for class names is a noble endeavour, they provide no additional information to the visitor of a website; take them away and a document will have exactly the same semantic value.

I didn’t always think this was the case, but the real world has a habit of changing your opinion. Much of my thinking around semantics has been informed by the writing of my peers. In “About HTML semantics and front-end architecture”, Nicholas Gallagher wrote:


	The important thing for class name semantics in non-trivial applications is that they be driven by pragmatism and best serve their primary purpose – providing meaningful, flexible, and reusable presentational/behavioural hooks for developers to use.


These thoughts are echoed by Harry Roberts in his CSS Guidelines:


	The debate surrounding semantics has raged for years, but it is important that we adopt a more pragmatic, sensible approach to naming things in order to work more efficiently and effectively. Instead of focussing on ‘semantics’, look more closely at sensibility and longevity – choose names based on ease of maintenance, not for their perceived meaning.


Naming methodologies

Front-end development has undergone a revolution in recent years. As the projects we’ve worked on have grown larger and more important, our development practices have matured. The pros and cons of object-orientated approaches to CSS can be endlessly debated, yet their introduction has highlighted the usefulness of having documented naming schemes.

Jonathan Snook’s SMACSS (Scalable and Modular Architecture for CSS) collects style rules into five categories: base, layout, module, state and theme. This grouping makes it clear what each rule does, and is aided by a naming convention:


	By separating rules into the five categories, naming convention is beneficial for immediately understanding which category a particular style belongs to and its role within the overall scope of the page. On large projects, it is more likely to have styles broken up across multiple files. In these cases, naming convention also makes it easier to find which file a style belongs to.

	I like to use a prefix to differentiate between layout, state and module rules. For layout, I use l- but layout- would work just as well. Using prefixes like grid- also provide enough clarity to separate layout styles from other styles. For state rules, I like is- as in is-hidden or is-collapsed. This helps describe things in a very readable way.


SMACSS is more a set of suggestions than a rigid framework, so its ideas can be incorporated into your own practice. Nicholas Gallagher’s SUIT CSS project is far more strict in its naming conventions:


	SUIT CSS relies on structured class names and meaningful hyphens (i.e., not using hyphens merely to separate words). This helps to work around the current limits of applying CSS to the DOM (i.e., the lack of style encapsulation), and to better communicate the relationships between classes.


Over the last year, I’ve favoured a BEM-inspired approach to CSS. BEM stands for block, element, modifier, which describes the three types of rule that contribute to the style of a single component. This means that, given the following markup:

<ul class=“sleigh”>
    <li class=“sleigh__reindeer sleigh__reindeer––famous”>Rudolph</li>
    <li class=“sleigh__reindeer”>Dasher</li>
    <li class=“sleigh__reindeer”>Dancer</li>
    <li class=“sleigh__reindeer”>Prancer</li>
    <li class=“sleigh__reindeer”>Vixen</li>
    <li class=“sleigh__reindeer”>Comet</li>
    <li class=“sleigh__reindeer”>Cupid</li>
    <li class=“sleigh__reindeer”>Dunder</li>
    <li class=“sleigh__reindeer”>Blixem</li>
</ul>

I know that:


	.sleigh is a containing block or component.
	.sleigh__reindeer is used only as a descendent element of .sleigh.
	.sleigh__reindeer––famous is used only as a modifier of .sleigh__reindeer.


With this naming scheme in place, I know which styles relate to a particular component, and which are shared. Beyond reducing specificity-related head-scratching, this approach has given me a framework within which I can consistently label items, and has sped up my workflow considerably.

Each of these methodologies shows that any robust CSS naming convention will have clear rules around case (lowercase, camelCase, PascalCase) and the use of special (allowed) characters like hyphens and underscores.

What makes for a good name?

Regardless of higher-level conventions, there’s no getting away from the fact that, at some point, we’re still going to have to name things. Recognising that classes should be named with other developers in mind, what makes for a good name?

Understandable

The most important aspect is for a name to be understandable. Words used in your project may come from a variety of sources: some may be widely understood, and others only be recognised by people working within a particular environment.


	Culture
Most words you’ll choose will have common currency outside the world of web development, although they may have a particular interpretation among developers (think menu, list, input). However, words may have a narrower cultural significance; for example, in Germany and other German-speaking countries, impressum is the term used for legally mandated statements of ownership.
	Industry
Industries often use specific terms to describe common business practices and concepts. Publishing has a number of these (headline, standfirst, masthead, colophon…) all have well understood meanings – and not all of them are relevant to online usage.
	Organisation
Companies may have internal names (or nicknames) for their products and services. The Guardian is rife with such names: bisons (and buffalos), pixies (and super-pixies), bentos (and mini-bentos)… all of which mean something very different outside the organisation. Although such names can be useful inside smaller teams, in larger organisations they can become a barrier to entry, a sort of secret code used among employees who have been around long enough to know what they mean.
	Product
Your team will undoubtedly have created names for specific features or interface components used in your product. For example, at Clearleft we coined the term gravigation for a navigation bar that was pinned to the bottom of the viewport. Elements of a visual design language may have names, too. Transport for London’s bar and circle logo is known internally as the roundel, while Nike’s logo is called the swoosh. Branding agencies often christen colours within a brand palette, too, either to evoke aspects of the identity or to indicate intended usage.


Once you recognise the origin of the words you use, you’ll be better able to judge their appropriateness. Using Latin words for class names may satisfy a need to use semantic-sounding terms but, unless you work in a company whose employees have a basic grasp of Latin, a degree of translation will be required. Military ranks might be a clever way of declaring sizes without implying actual values, but I’d venture most people outside the armed forces don’t know how they’re ordered.

Obvious

Quite often, the first name that comes into your head will be the best option. Names that obliquely reference the function of a class (e.g. receptacle instead of container, kevlar instead of no-bullets) only serve to add an additional layer of abstraction. Don’t overthink it!

One way of knowing if the names you use are well understood is to look at what similar concepts are called in existing vocabularies. schema.org, Dublin Core and the BBC’s ontologies are all useful sources for object names.

Functional

While we’ve learned to avoid using presentational classes, there remains a tension between naming things based on their content, and naming them for their intended presentation or behaviour (which may change at different breakpoints). Rather than think about a component’s appearance or behaviour, instead look to its function, its purpose. To clarify, ask what a component’s function is, and not how the component functions.

For example, the Guardian’s internal content system uses the following names for different types of image placement: supporting, showcase and thumbnail, with inline being the default. These options make no promise of the resulting position on a webpage (or smartphone app, or television screen…), but do suggest intended use, and therefore imply the likely presentation.

Consistent

Being consistent in your approach to names will allow for easier naming of successive components, and extending the vocabulary when necessary. For example, a predictably named hierarchy might use names like primary and secondary. Should another level need to be added, tertiary is clearly be preferred over third.

Appropriate

Your project will feature a mix of style rules. Some will perform utility functions (clearing floats, removing bullets from a list, reseting margins), while others will perform specific functions used only once or twice in a project. Names should reflect this. For commonly used classes, be generic; for unique components be more specific.

It’s also worth remembering that you can use multiple classes on an element, so combining both generic and specific can give you a powerful modular design system:


	Generic: list
	Specific: naughty-children
	Combined: naughty-children list


If following the BEM methodology, you might use the following classes:


	Generic: list
	Specific: list––nice-children
	Combined: list list––nice-children


Extensible

Good naming schemes can be extended. One way of achieving this is to use namespaces, which are basically a way of grouping related names under a higher-level term.

Microformats are a good example of a well-designed naming scheme, with many of its vocabularies taking property names from existing and related specifications (e.g. hCard is a 1:1 representation of vCard). Microformats 2 goes one step further by grouping properties under several namespaces:


	h-* for root class names (e.g. h-card)
	p-* for simple (text) properties (e.g. p-name)
	u-* for URL properties (e.g. u-photo)
	dt-* for date/time properties (e.g. dt-bday)
	e-* for embedded markup properties (e.g. e-note)


The inclusion of namespaces is a massive improvement over the earlier specification, but the downside is that microformats now occupy five separate namespaces. This might be problematic if you are using u-* for your utility classes. While nothing will break, your naming system won’t be as robust, so plan accordingly.

(Note: Microformats perform a very specific function, separate from any presentational concerns. It’s therefore considered best practice to not use microformat classes as styling hooks, but instead use additional classes that relate to the function of the component and adhere to your own naming conventions.)

Short

Names should be as long as required, but no longer. When looking for words to describe a particular function, I try to look for single words where possible. Avoid abbreviations unless they are understood within the contexts described above. rrp is fine if labelling a recommended retail price in an online shop, but not very helpful if used to mean ragged-right paragraph, for example.

Fun!

Finally, names can be an opportunity to have some fun! Names can give character to a project, be it by providing an outlet for in-jokes or adding little easter eggs for those inclined to look.

The copyright statement on Apple’s website has long been named sosumi, a word that has a nice little history inside Apple. Until recently, the hamburger menu icon on the Guardian website was labelled honest-burger, after the developer’s favourite burger restaurant.

A few thoughts on preprocessors

CSS preprocessors have solved a lot of problems, but they have an unfortunate downside: they require you to name yet more things! Whereas we needed to worry only about style rules, now we need names for variables, mixins, functions… oh my!

A second article could be written about naming these, so for now I’ll offer just a few thoughts. The first is to note that preprocessors make it easier to change things, as they allow for DRYer code. So while the names of variables are important (and the advice in this article still very much applies), you can afford to relax a little.

Looking to name colour variables? If possible, find out if colours have been assigned names in a brand palette. If not, use obvious names (based on appearance or function, depending on your preference) and adapt as the palette grows. If it becomes difficult to name colours that are too similar, I’d venture that the problem lies with the design rather than the naming scheme.

The same is true for responsive breakpoints. Preprocessors allow you to move awkward naming conventions out of the markup and into the CSS. Although terms like mobile, tablet and desktop are not desirable given the need to think about device-agnostic design, if these terms are widely understood within a product team and among stakeholders, using them will ensure everyone is using the same language (they can always be changed later).

It still feels like we’re at the very beginning of understanding how preprocessors fit into a development workflow, if at all! I suspect over the next few years, best practices will emerge for all of these considerations. In the meantime, use your brain!



Even with sensible rules and conventions in place, naming things can remain difficult, but hopefully I’ve made this exercise a little less painful. Christmas is a time of giving, so to the developer reading your code in a year’s time, why not make your gift one of clearer class names.",2014,Paul Lloyd,paulrobertlloyd,2014-12-21T00:00:00+00:00,https://24ways.org/2014/naming-things/,code
39,Meet for Learning,"“I’ve never worked in a place like this,” said one of my direct reports during our daily stand-up meeting.

And with that statement, my mind raced to the most important thing about lawyering that I’ve learned from decades of watching lawyers lawyer on TV: don’t ask a question you don’t know the answer to.

But I couldn’t stop myself. I wanted to learn more. The thought developed in my mind. The words formed in my mouth. And the vocalization occurred: “A place like this?”

“I’ve never worked where people are so honest and transparent about things.”

Designing a learning-centered culture

Before we started Center Centre, Jared Spool and I discussed both the larger goals and the smaller details of this new UX design school. We talked about things like user experience, curriculum, and structure.

We discussed the pattern we saw in our research. Hiring managers told us time and again that great designers have excellent technical and interpersonal skills. But, more importantly, the best designers are lifelong learners—they are willing and able to learn how to do new things. Learning this led us to ask a critical question: how would we intentionally design a learning-centered experience?

To craft the experience we were aiming for, we knew we had to create a learning-centered culture for our students and our employees. We knew that our staff would need to model the behaviors our students needed to learn. We knew the best way to shape the culture was to work with our direct reports—our directs—to develop the behaviors we wanted them to exemplify.

To craft the experience we were aiming for, we knew we had to create a learning-centered culture for our students and our employees. We knew that our staff would need to model the behaviors our students needed to learn.

Building a learning team

Our learning-centered culture starts with our staff. We believe in transparency. Transparency builds trust. Effective organizations have effective teams who trust each other as individuals.

One huge way we build that trust and provide opportunities for transparency is in our meetings. (I know, I know—meetings! Yuck!) But seriously, running and participating in effective meetings is a great opportunity to build a learning-centered culture.

Meetings—when done well—allow individuals time to come together, to share, and to listen. These behaviors, executed on a consistent and regular basis, build honest and trusting relationships.

An effective meeting is one that achieves the desired outcomes of that meeting. While different meetings aim for different results, at Center Centre all meetings have a secondary goal: meet for learning.

A framework for learning-centered meetings

We’ve developed a framework for our meetings. We use it for all our meetings, which means attendees know what to expect. It also saves us from reinventing the wheel in each meeting.

These basic steps help our meetings focus on the valuable face-to-face interaction we’re having, and help us truly begin to learn from one another.

 An agenda for a staff meeting.

Use effective meeting basics


	Prepare for the meeting before the meeting.
	If you’re running the meeting, prepare a typed agenda and share it before the meeting. Agendas have start times for each item.
	Start the meeting on time. Don’t wait for stragglers.
	Define ground rules. Get input from attendees. Recurring meetings don’t have to do this every time.
	Keep to the meeting agenda. Put off-topic questions and ideas in a parking lot, a visual document that everyone can see, so you can address the questions and ideas later.
	Finish on time. And if you’ve reached the meeting’s goals, finish early.


 Parking lots where ideas on sticky notes can be posted for later consideration.

Focus to learn


	Have tech-free meetings: no laptops, no phones, no things with notifications.
	Bring a notebook and a pen.
	Take notes by hand. You’re not taking minutes, you’re writing to learn.


Come with a learning mindset


	Ask: what are our goals for this meeting? (Hopefully answered by the meeting agenda.)
	Ask: what can I learn overall?
	Ask: what can I learn from each of my colleagues?
	Ask: what can I share that will help the team learn overall?
	Ask: what can I share that will help each of my colleagues learn?


Investing in regularly scheduled learning-centered meetings

At Center Centre, we have two types of recurring all-staff meetings: daily stand-ups and weekly staff meetings. (We are a small organization, so it makes sense to meet as an entire group.)

Yes, that means we spend thirty minutes each day in stand-up, for a total of two and a half hours of stand-up meeting time each week. And, yes, we also have a weekly ninety-minute sit-down staff meeting on top of that. This investment in time is an investment in learning.

We use these meetings to build our transparency, and, therefore, our trust. The regularity of these meetings helps us maintain ongoing, open sharing about our responsibilities, our successes, and our learning.

For instance, we answer five questions in our stand-up:


	What did I get done since the last stand-up (I reported at)?
	What is my goal to accomplish before the next stand-up?
	What’s preventing me from getting these things done, if anything?
	What’s the highest risk or most unknown thing right now about what I’m trying to get done?
	What is the most important thing I learned since the last time we met and how will what I learned change the way I approach things in the future?


Each person writes out their answers to these questions before the meeting. Each person brings their answers printed on paper to the meeting. And each person brings a pen to jot down notes.

 Notes compiled for a stand-up meeting.

During the stand-up, each person shares their answers to the five questions. To sustain a learning-centered culture, the fifth question is the most important question to answer. It allows individual reflection focused on learning. Sometimes this isn’t an easy question to answer. It makes us stretch. It makes us think.

By sharing our individual answers to the fifth question, we open ourselves up to the group. When we honestly share what we’ve learned, we openly admit that we didn’t know something. Sharing like this would be scary (and even risky) if we didn’t have a learning-centered culture.

We often share the actual process of how we learned something. By listening, each of us is invited to learn more about the topic at hand, consider what more there is to learn about that topic, and even gain insights into other methods of learning—which can be applied to other topics.

Sharing the answers to the fifth question also allows opportunities for further conversations. We often take what someone has individually learned and find ways to apply it for our entire team in support of our organization. We are, after all, learning together.

Building individual learners

We strive to grow together as a team at Center Centre, but we don’t lose sight of the importance of the individuals who form our team. As individuals, we bring our goals, dreams, abilities, and prior knowledge to the team.

To build learning teams, we must build individual learners. A team made up of lifelong learners, who share their learning and learn from each other, is a team that will continually produce better results.

As a manager, I need to meet each direct where they are with their current abilities and knowledge. Then, I can help them take their skills and knowledge base to the next levels. This process requires each individual direct to engage in professional development.

We believe effective managers help their directs engage in behaviors that support growth and development. Effective managers encourage and support learning.



Our weekly one-on-ones

One way we encourage learning is through weekly one-on-ones. Each of my directs meets with me, individually, for thirty minutes each week. The meeting is their meeting. It is not my meeting.

My direct sets the agenda. They talk about what they want to talk about. They can talk about work. They can talk about things outside of work. They can talk about their health, their kids, and even their cat. Whatever is important to them is important to me. I listen. I take notes.

Although the direct sets the specific agenda, the meeting has three main parts. Approximately ten minutes for them (the direct), ten minutes for me (the manager), and ten minutes for us to talk about their future within—and beyond—our organization.

Coaching for future performance

The final third of our one-on-one is when I coach my directs. Coaching looks to the direct’s future performance. It focuses on developing the direct’s skills.

Coaching isn’t hard. It doesn’t take much time. For me, it usually takes less than five minutes a week during a one-on-one.

The first time I coach one of my directs, I ask them to brainstorm about the skills they want to improve. They usually already have an idea about this. It’s often something they’ve wanted to work on for some time, but didn’t think they had the time or the knowhow to improve.

If a direct doesn’t know what they want to improve, we discuss their job responsibilities—specifically the aspects of the job that concern them.

Coaching provides an opportunity for me to ask, “In your job, what are the required skills that you feel like you don’t have (or know well enough, or perform effectively, or use with ease)?”

Sometimes I have to remind a direct that it’s okay not to know how to do something (even if it’s a required part of their job). After all, our organization is a learning organization. In a learning organization, no one knows everything but everyone is willing to learn anything.

After we review the job responsibilities together, I ask my direct what skill they’d like to work to improve. Whatever they choose, we focus on that skill for coaching—I’ve found my directs work better when they’re internally motivated.

Sometimes the first time I talk with a direct about coaching, they get a bit anxious. If this happens, I share a personal story about my professional learning journey. I say something like:


	I didn’t know how to make a school before we started to make Center Centre.

	I didn’t know how to manage an entire team of people—day in and day out—until I started managing a team of people every day.

	When I realized that I was the boss—and that the success of the school would hinge, at least in part, on my skills as a manager—I was a bit terrified. I was missing an important skill set that I needed to know (and I needed to know well).

	When I first understood this, I felt bad—like I should have already known how to be a great manager. But then I realized, I’d never faced this situation. I’d never needed to know how to use this skill set in this way.

	I worked through my anxiety about feeling inadequate. I decided I’d better learn how to be an effective manager because the school needed me to be one. You needed me to be one.

	Every day, I work to improve my management skills. You’ve probably noticed that some days I’m better at it than others. I try not to beat myself up about this, although it’s hard—I’d like to be perfect at it. But I’m not.

	I know that if I make a conscious, daily effort to learn how to be a better manager, I’ll continue to improve. So that’s what I do.

	Every day I learn. I learn by doing. I learn how to be better than I was the day before. That’s what I ask of you.


Once we determine the skill the direct wants to learn, we figure out how they can go about learning it. I ask: “How could you learn this skill?”

We brainstorm for two or three minutes about this. We write down every idea that comes to mind, and we write it so both of us can easily see the options (both whiteboards and sticky notes on the wall work well for this exercise).


	Read a book. Research online. Watch a virtual seminar. Listen to a podcast. Talk to a mentor. Reach out to an expert. Attend a conference. Shadow someone else while they do the skill. Join a professional organization.


The goal is to get the direct on a path of self-development. I’m coaching their development, but I’m not the main way my direct will learn this new skill.

I ask my direct which path seems like the best place to start. I let them choose whatever option they want (as long as it works with our budget). They are more likely to follow through if they are in control of this process.

Next, we work to break down the selected path into tasks. We only plan one week’s worth of tasks. The tasks are small, and the deadlines are short. My direct reports when each task is completed.

At our next one-on-one, I ask my direct about their experience learning this new skill.

Rinse. Repeat.

That’s it. I spend five minutes a week talking with each direct about their individual learning. They develop their professional skills, and together we’re creating a learning-centered culture.

Asking questions I don’t know the answer to

When my direct said, “I’ve never worked where people are so honest and transparent about things,” it led me to believe that all this is working. We are building a learning-centered culture.

This week I was reminded that creating a learning-centered culture starts not just with the staff, but with me. When I challenge myself to learn and then share what I’m currently learning, my directs want to learn more about what I’m learning about.

For example, I decided I needed to improve my writing skills. A few weeks ago, I realized that I was sorely out of practice and I felt like I had lost my voice. So I started to write. I put words on paper. I felt overwhelmed. I felt like I didn’t know how to write anymore (at least not well or effectively).

I bought some books on writing (mostly Peter Elbow’s books like Writing with Power, Writing Without Teachers, and Vernacular Eloquence), and I read them. I read them all. Reading these books was part of my personal coaching. I used the same steps to coach myself as I use with my directs when I coach them.

In stand-ups, I started sharing what I accomplished (like I completed one of the books) and what I learned by doing—specific things, like engaging in freewriting and an open-ended writing process.

This week, I went to lunch with one of my directs. She said, “You’ve been talking about freewriting a lot. You’re really excited about it. Freewriting seems like it’s helping your writing process. Would you tell me more about it?”

So I shared the details with her. I shared the reasons why I think freewriting is helping. I’m not focused on perfection. Instead, each day I’m focused on spending ten, uninterrupted minutes writing down whatever comes to my mind. It’s opening my writing mind. It’s allowing my words to flow more freely. And it’s helping me feel less self-conscious about my writing.

She said, “Leslie, when you say you’re self-conscious about your writing, I laugh. Not because it’s funny. But because when I read what you write, I think, ‘What is there to improve?’ I think you’re a great writer. It’s interesting to know that you think you can be a better writer. I like learning about your learning process. I think I could do freewriting. I’m going to give it a try.”

There’s something magical about all of this. I’m not even sure I can eloquently put it into words. I just know that our working environment is something very different. I’ve never experienced anything quite like it. Somehow, by sharing that I don’t know everything and that I’m always working to learn more, I invite my directs to be really open about what they don’t know. And they see it’s possible always to learn and grow.

I’m glad I ignore all the lawyering I’ve learned from watching TV. I’m glad I ask the questions I don’t know the answers to. And I’m glad my directs do the same. When we meet for learning, we accelerate and amplify the learning process—building individual learners and learning teams. Embracing the unknown and working toward understanding is what makes our culture a learning-centered culture.

30,"Making Sites More Responsive, Responsibly","With digital projects we’re used to shifting our thinking to align with our target audience. We may undertake research, create personas, identify key tasks, or observe usage patterns, with our findings helping to refine our ongoing creations. A product’s overall experience can make or break its success, and when it comes to defining these experiences our development choices play a huge role alongside more traditional user-focused activities.

The popularisation of responsive web design is a great example of how we are able to shape the web’s direction through using technology to provide better experiences. If we think back to the move from table-based layouts to CSS, initially our clients often didn’t know or care about the difference in these approaches, but we did. Responsive design was similar in this respect – momentum grew through the web industry choosing to use an approach that we felt would give a better experience, and which was more future-friendly. 

We tend to think of responsive design as a means of displaying content appropriately across a range of devices, but the technology and our implementation of it can facilitate much more. A responsive layout not only helps your content work when the newest smartphone comes out, but it also ensures your layout suitably adapts if a visually impaired user drastically changes the size of the text.

 The 24 ways site at 400% on a Retina MacBook Pro displays a layout more typically used for small screens.

When we think more broadly, we realise that our technical choices and approaches to implementation can have knock-on effects for the greater good, and beyond our initial target audiences. We can make our experiences more responsive to people’s needs, enhancing their usability and accessibility along the way.

Being responsibly responsive

Of course, when we think about being more responsive, there’s a fine line between creating useful functionality and becoming intrusive and overly complex. In the excellent Responsible Responsive Design, Scott Jehl states that:


A responsible responsive design equally considers the following throughout a project:

Usability: The way a website’s user interface is presented to the user, and how that UI responds to browsing conditions and user interactions.
Access: The ability for users of all devices, browsers, and assistive technologies to access and understand a site’s features and content.
Sustainability: The ability for the technology driving a site or application to work for devices that exist today and to continue to be usable and accessible to users, devices, and browsers in the future.
Performance: The speed at which a site’s features and content are perceived to be delivered to the user and the efficiency with which they operate within the user interface.



Scott’s book covers these ideas in a lot more detail than I’ll be able to here (put it on your Christmas list if it’s not there already), but for now let’s think a bit more about our roles as digital creators and the power this gives us.

Our choices around technology and the decisions we have to make can be extremely wide-ranging. Solutions will vary hugely depending on the needs of each project, though we can further explore the concept of making our creations more responsive through the use of humble web technologies.

The power of the web

We all know that under the HTML5 umbrella are some great new capabilities, including a number of JavaScript APIs such as geolocation, web audio, the file API and many more. We often use these to enhance the functionality of our sites and apps, to add in new features, or to facilitate device-specific interactions.

You’ll have seen articles with flashy titles such as “Top 5 JavaScript APIs You’ve Never Heard Of!”, which you’ll probably read, think “That’s quite cool”, yet never use in any real work.

There is great potential for technologies like these to be misused, but there are also great prospects for them to be used well to enhance experiences. Let’s have a look at a few examples you may not have considered.

Offline first

When we make websites, many of us follow a process which involves user stories – standardised snippets of context explaining who needs what, and why.

“As a student I want to pay online for my course so I don’t have to visit the college in person.”

“As a retailer I want to generate unique product codes so I can manage my stock.”

We very often focus heavily on what needs doing, but may not consider carefully how it will be done. As in Scott’s list, accessibility is extremely important, not only in terms of providing a great experience to users of assistive technologies, but also to make your creation more accessible in the general sense – including under different conditions.

Offline first is yet another ‘first’ methodology (my personal favourite being ‘tea first’), which encourages us to develop so that connectivity itself is an enhancement – letting users continue with tasks even when they’re offline. Despite the rapid growth in public Wi-Fi, if we consider data costs and connectivity in developing countries, our travel habits with planes, underground trains and roaming (or simply if you live in the UK’s signal-barren East Anglian wilderness as I do), then you’ll realise that connectivity isn’t as ubiquitous as our internet-addled brains would make us believe. Take a scenario that I’m sure we’re all familiar with – the digital conference. Your venue may be in a city served by high-speed networks, but after overloading capacity with a full house of hashtag-hungry attendees, each carrying several devices, then everyone’s likely to be offline after all. Wouldn’t it be better if we could do something like this instead?


	Someone visits our conference website.
	On this initial run, some assets may be cached for future use: the conference schedule, the site’s CSS, photos of the speakers.
	When the attendee revisits the site on the day, the page shell loads up from the cache.
	If we have cached content (our session timetable, speaker photos or anything else), we can load it directly from the cache. We might then try to update this, or get some new content from the internet, but the conference attendee already has a base experience to use.
	If we don’t have something cached already, then we can try grabbing it online.
	If for any reason our requests for new content fail (we’re offline), then we can display a pre-cached error message from the initial load, perhaps providing our users with alternative suggestions from what is cached.


There are a number of ways we can make something like this, including using the application cache (AppCache) if you’re that way inclined. However, you may want to look into service workers instead. There are also some great resources on Offline First! if you’d like to find out more about this.

Building in offline functionality isn’t necessarily about starting offline first, and it’s also perfectly possible to retrofit sites and apps to catch offline scenarios, but this kind of graceful degradation can end up being more complex than if we’d considered it from the start. By treating connectivity as an enhancement, we can improve the experience and provide better performance than we can when waiting to counter failures. Our websites can respond to connectivity and usage scenarios, on top of adapting how we present our content. Thinking in this way can enhance each point in Scott’s criteria.

As I mentioned, this isn’t necessarily the kind of development choice that our clients will ask us for, but it’s one we may decide is simply the right way to build based on our project, enhancing the experience we provide to people, and making it more responsive to their situation.

Even more accessible

We’ve looked at accessibility in terms of broadening when we can interact with a website, but what about how? Our user stories and personas are often of limited use. We refer in very general terms to students, retailers, and sometimes just users. What if we have a student whose needs are very different from another student? Can we make our sites even more usable and accessible through our development choices?

Again using JavaScript to illustrate this concept, we can do a lot more with the ways people interact with our websites, and with the feedback we provide, than simply accepting keyboard, mouse and touch inputs and displaying output on a screen.

Input

Ambient light detection is one of those features that looks great in simple demos, but which we struggle to put to practical use. It’s not new – many satnav systems automatically change the contrast for driving at night or in tunnels, and our laptops may alter the screen brightness or keyboard backlighting to better adapt to our surroundings. Using web technologies we can adapt our presentation to be better suited to ambient light levels.

If our device has an appropriate light sensor and runs a browser that supports the API, we can grab the ambient light in units using ambient light events, in JavaScript. We may then change our presentation based on different bandings, perhaps like this:

window.addEventListener('devicelight', function(e) {
    var lux = e.value;

    if (lux < 50) {
        //Change things for dim light
    }
    if (lux >= 50 && lux <= 10000) {
        //Change things for normal light
    }
    if (lux > 10000) {
        //Change things for bright light
    }
});

Live demo (requires light sensor and supported browser).

Soon we may also be able to do such detection through CSS, with light-level being cited in the Media Queries Level 4 specification. If that becomes the case, it’ll probably look something like this:

@media (light-level: dim) {
  /*Change things for dim light*/
}

@media (light-level: normal) {
  /*Change things for normal light*/
}

@media (light-level: washed) {
  /*Change things for bright light*/
}

While we may be quick to dismiss this kind of detection as being a gimmick, it’s important to consider that apps such as Light Detector, listed on Apple’s accessibility page, provide important context around exactly this functionality.


	“If you are blind, Light Detector helps you to be more independent in many daily activities. At home, point your iPhone towards the ceiling to understand where the light fixtures are and whether they are switched on. In a room, move the device along the wall to check if there is a window and where it is. You can find out whether the shades are drawn by moving the device up and down.”

	everywaretechnologies.com/apps/lightdetector


Input can be about so much more than what we enter through keyboards. Both an ever increasing amount of available sensors and more APIs being supported by the major browsers will allow us to cater for more scenarios and respond to them accordingly. This can be as complex or simple as you need; for instance, while x-webkit-speech has been deprecated, the web speech API is available for a number of browsers, and research into sign language detection is also being performed by organisations such as Microsoft.

Output

Web technologies give us some great enhancements around input, allowing us to adapt our experiences accordingly. They also provide us with some nice ways to provide feedback to users.

When we play video games, many of our modern consoles come with the ability to have rumble effects on our controller pads. These are a great example of an enhancement, as they provide a level of feedback that is entirely optional, but which can give a great deal of extra information to the player in the right circumstances, and broaden the scope of our comprehension beyond what we’re seeing and hearing.

Haptic feedback is possible on the web as well. We could use this in any number of responsible applications, such as alerting a user to changes or using different patterns as a communication mechanism. If you find yourself in a pickle, here’s how to print out SOS in Morse code through the vibration API. The following code indicates the length of vibration in milliseconds, interspersed by pauses in milliseconds.

navigator.vibrate([100, 300, 100, 300, 100, 300, 600, 300, 600, 300, 600, 300, 100, 300, 100, 300, 100]);

Live demo (requires supported browser)

With great power…

What you’ve no doubt come to realise by now is that these are just more examples of progressive enhancement, whose inclusion will provide a better experience if the capabilities are available, but which we should not rely on. This idea isn’t new, but the most important thing to remember, and what I would like you to take away from this article, is that it is up to us to decide to include these kind of approaches within our projects – if we don’t root for them, they probably won’t happen. This is where our professional responsibility comes in.

We won’t necessarily be asked to implement solutions for the scenarios above, but they illustrate how we can help to push the boundaries of experiences. Maybe we’ll have to switch our thinking about how we build, but we can create more usable products for a diverse range of people and usage scenarios through the choices we make around technology. Let’s stop thinking simply in terms of features inside a narrow view of our target users, and work out how we can extend these to cater for a wider set of situations.

When you plan your next digital project, consider the power of the web and the enhancements we can use, and try to make your projects even more responsive and responsible.",2014,Sally Jenkinson,sallyjenkinson,2014-12-10T00:00:00+00:00,https://24ways.org/2014/making-sites-more-responsive-responsibly/,code
37,JavaScript Modules the ES6 Way,"JavaScript admittedly has plenty of flaws, but one of the largest and most prominent is the lack of a module system: a way to split up your application into a series of smaller files that can depend on each other to function correctly. 

This is something nearly all other languages come with out of the box, whether it be Ruby’s require, Python’s import, or any other language you’re familiar with. Even CSS has @import! JavaScript has nothing of that sort, and this has caused problems for  application developers as they go from working with small websites to full client-side applications. Let’s be clear: it doesn’t mean the new module system in the upcoming version of JavaScript won’t be useful to you if you’re building smaller websites rather than the next Instagram.

Thankfully, the lack of a module system will soon be a problem of the past. The next version of JavaScript, ECMAScript 6, will bring with it a full-featured module and dependency management solution for JavaScript. The bad news is that it won’t be landing in browsers for a while yet – but the good news is that the specification for the module system and how it will look has been finalised. The even better news is that there are tools available to get it all working in browsers today without too much hassle. In this post I’d like to give you the gift of JS modules and show you the syntax, and how to use them in browsers today. It’s much simpler than you might think.

What is ES6?

ECMAScript is a scripting language that is standardised by a company called Ecma International. JavaScript is an implementation of ECMAScript. ECMAScript 6 is simply the next version of the ECMAScript standard and, hence, the next version of JavaScript. The spec aims to be fully comfirmed and complete by the end of 2014, with a target initial release date of June 2015. It’s impossible to know when we will have full feature support across the most popular browsers, but already some ES6 features are landing in the latest builds of Chrome and Firefox. You shouldn’t expect to be able to use the new features across browsers without some form of additional tooling or library for a while yet.

The ES6 module spec

The ES6 module spec was fully confirmed in July 2014, so all the syntax I will show you in this article is not expected to change. I’ll first show you the syntax and the new APIs being added to the language, and then look at how to use them today. There are two parts to the new module system. The first is the syntax for declaring modules and dependencies in your JS files, and the second is a programmatic API for loading in modules manually. The first is what most people are expected to use most of the time, so it’s what I’ll focus on more.

Module syntax

The key thing to understand here is that modules have two key components. First, they have dependencies. These are things that the module you are writing depends on to function correctly. For example, if you were building a carousel module that used jQuery, you would say that jQuery is a dependency of your carousel. You import these dependencies into your module, and we’ll see how to do that in a minute. Second, modules have exports. These are the functions or variables that your module exposes publicly to anything that imports it. Using jQuery as the example again, you could say that jQuery exports the $ function. Modules that depend on and hence import jQuery get access to the $ function, because jQuery exports it.

Another important thing to note is that when I discuss a module, all I really mean is a JavaScript file. There’s no extra syntax to use other than the new ES6 syntax. Once ES6 lands, modules and files will be analogous.

Named exports

Modules can export multiple objects, which can be either plain old variables or JavaScript functions. You denote something to be exported with the export keyword:

export function double(x) {
  return x + x;
};


You can also store something in a variable then export it. If you do that, you have to wrap the variable in a set of curly braces.

var double = function(x) {
  return x + x;
}

export { double };

A module can then import the double function like so:

import { double } from 'mymodule';
double(2); // 4

Again, curly braces are required around the variable you would like to import. It’s also important to note that from 'mymodule' will look for a file called mymodule.js in the same directory as the file you are requesting the import from. There is no need to add the .js extension.

The reason for those extra braces is that this syntax lets you export multiple variables:

var double = function(x) {
  return x + x;
}

var square = function(x) {
  return x * x;
}

export { double, square }

I personally prefer this syntax over the export function …, but only because it makes it much clearer to me what the module exports. Typically I will have my export {…} line at the bottom of the file, which means I can quickly look in one place to determine what the module is exporting.

A file importing both double and square can do so in just the way you’d expect:

import { double, square } from 'mymodule';
double(2); // 4
square(3); // 9

With this approach you can’t easily import an entire module and all its methods. This is by design – it’s much better and you’re encouraged to import just the functions you need to use.

Default exports

Along with named exports, the system also lets a module have a default export. This is useful when you are working with a large library such as jQuery, Underscore, Backbone and others, and just want to import the entire library. A module can define its default export (it can only ever have one default export) like so:

export default function(x) {
  return x + x;
}

And that can be imported:

import double from 'mymodule';
double(2); // 4


This time you do not use the curly braces around the name of the object you are importing. Also notice how you can name the import whatever you’d like. Default exports are not named, so you can import them as anything you like:

import christmas from 'mymodule';
christmas(2); // 4

The above is entirely valid.

Although it’s not something that is used too often, a module can have both named exports and a default export, if you wish.

One of the design goals of the ES6 modules spec was to favour default exports. There are many reasons behind this, and there is a very detailed discussion on the ES Discuss site about it. That said, if you find yourself preferring named exports, that’s fine, and you shouldn’t change that to meet the preferences of those designing the spec.

Programmatic API

Along with the syntax above, there is also a new API being added to the language so you can programmatically import modules. It’s pretty rare you would use this, but one obvious example is loading a module conditionally based on some variable or property. You could easily import a polyfill, for example, if the user’s browser didn’t support a feature your app relied on. An example of doing this is:

if(someFeatureNotSupported) {
  System.import('my-polyfill').then(function(myPolyFill) {
    // use the module from here
  });
}

System.import will return a promise, which, if you’re not familiar, you can read about in this excellent article on HTMl5 Rocks by Jake Archibald. A promise basically lets you attach callback functions that are run when the asynchronous operation (in this case, System.import), is complete.

This programmatic API opens up a lot of possibilities and will also provide hooks to allow you to register callbacks that will run at certain points in the lifetime of a module. Those hooks and that syntax are slightly less set in stone, but when they are confirmed they will provide really useful functionality. For example, you could write code that would run every module that you import through something like JSHint before importing it. In development that would provide you with an easy way to keep your code quality high without having to run a command line watch task.

How to use it today

It’s all well and good having this new syntax, but right now it won’t work in any browser – and it’s not likely to for a long time. Maybe in next year’s 24 ways there will be an article on how you can use ES6 modules with no extra work in the browser, but for now we’re stuck with a bit of extra work.

ES6 module transpiler

One solution is to use the ES6 module transpiler, a compiler that lets you write your JavaScript using the ES6 module syntax (actually a subset of it – not quite everything is supported, but the main features are) and have it compiled into either CommonJS-style code (CommonJS is the module specification that NodeJS and Browserify use), or into AMD-style code (the spec RequireJS uses). There are also plugins for all the popular build tools, including Grunt and Gulp.

The advantage of using this transpiler is that if you are already using a tool like RequireJS or Browserify, you can drop the transpiler in, start writing in ES6 and not worry about any additional work to make the code work in the browser, because you should already have that set up already. If you don’t have any system in place for handling modules in the browser, using the transpiler doesn’t really make sense. Remember, all this does is convert ES6 module code into CommonJS- or AMD-compliant JavaScript. It doesn’t do anything to help you get that code running in the browser, but if you have that part sorted it’s a really nice addition to your workflow. If you would like a tutorial on how to do this, I wrote a post back in June 2014 on using ES6 with the ES6 module transpiler.

SystemJS

Another solution is SystemJS. It’s the best solution in my opinion, particularly if you are starting a new project from scratch, or want to use ES6 modules on a project where you have no current module system in place. SystemJS is a spec-compliant universal module loader: it loads ES6 modules, AMD modules, CommonJS modules, as well as modules that just add a variable to the global scope (window, in the browser).

To load in ES6 files, SystemJS also depends on two other libraries: the ES6 module loader polyfill; and Traceur. Traceur is best accessed through the bower-traceur package, as the main repository doesn’t have an easy to find downloadable version. The ES6 module load polyfill implements System.import, and lets you load in files using it. Traceur is an ES6-to-ES5 module loader. It takes code written in ES6, the newest version of JavaScript, and transpiles it into ES5, the version of JavaScript widely implemented in browsers. The advantage of this is that you can play with the new features of the language today, even though they are not supported in browsers. The drawback is that you have to run all your files through Traceur every time you save them, but this is easily automated. Additionally, if you use SystemJS, the Traceur compilation is done automatically for you.

All you need to do to get SystemJS running is to add a <script> element to load SystemJS into your webpage. It will then automatically load the ES6 module loader and Traceur files when it needs them. In your HTML you then need to use System.import to load in your module:

<script>
  System.import('./app');
</script>

When you load the page, app.js will be asynchronously loaded. Within app.js, you can now use ES6 modules. SystemJS will detect that the file is an ES6 file, automatically load Traceur, and compile the file into ES5 so that it works in the browser. It does all this dynamically in the browser, but there are tools to bundle your application in production, so it doesn’t make a lot of requests on the live site. In development though, it makes for a really nice workflow.

When working with SystemJS and modules in general, the best approach is to have a main module (in our case app.js) that is the main entry point for your application. app.js should then be responsible for loading all your application’s modules. This forces you to keep your application organised by only loading one file initially, and having the rest dealt with by that file.

SystemJS also provides a workflow for bundling your application together into one file.

Conclusion

ES6 modules may be at least six months to a year away (if not more) but that doesn’t mean they can’t be used today. Although there is an overhead to using them now – with the work required to set up SystemJS, the module transpiler, or another solution – that doesn’t mean it’s not worthwhile. Using any module system in the browser, whether that be RequireJS, Browserify or another alternative, requires extra tooling and libraries to support it, and I would argue that the effort to set up SystemJS is no greater than that required to configure any other tool. It also comes with the extra benefit that when the syntax is supported in browsers, you get a free upgrade. You’ll be able to remove SystemJS and have everything continue to work, backed by the native browser solution.

If you are starting a new project, I would strongly advocate using ES6 modules. It is a syntax and specification that is not going away at all, and will soon be supported in browsers. Investing time in learning it now will pay off hugely further down the road.

45,Is Agile Harder for Agencies?,"I once sat in a pitch meeting and watched a new business exec tell a potential client that his agency followed an agile workflow process at all times. The potential client nodded wisely, and they both agreed that agile was indeed the way to go.

The meeting progressed and they signed off on a contract for a massive project, to be delivered in a standard waterfall fashion, with all manner of phases and key deliverables.

Of course both of them left the meeting perfectly happy, because neither of them knew nor cared what an agile workflow process might be.

That was about five years ago. As 2015 heaves into view I think it’s fair to say that attitudes have changed. Perhaps the same number of people claim to do Agile™ now as in 2010, but I think more of them are telling the truth.

As a developer in an agency that works primarily with larger organisations, this year I have started to see a shift from agencies pushing agile methodologies with their clients, to clients requesting and even demanding agile practices from their agencies. Only a couple of years ago this would have been unusual behaviour.

So what’s the problem?

We should be happy then, no? Those of us in agencies will get to spend more time delivering great products, and less time arguing over out-of-date functional specs or battling through an adversarial change management procedure because somebody had a good idea during development rather than planning. We get to be a little bit more like our brothers and sisters in vaunted teams like the Government Digital Service, which is using agile approaches to great effect on projects that have a real benefit to their users.

Almost. Unfortunately, it seems to be the case that adhering to an agile framework such as scrum is more difficult within an agency/client structure than it is for an in-house development team.

This is no surprise. The Agile Manifesto was written in 2001 by a group of software developers for their own use. Many of the underlying principles of a framework like Scrum assume the existence of an in-house team, working on a highly technical project, and working for the business that employs them. The agency/client model must to some extent be retrofitted into agile frameworks. It can be done though, and there are plenty of agencies out there doing it well.

This article isn’t meant to be another introduction to agile techniques – there are too many of those online already. This article is for people just dipping their toes into this way of working. I’ve laid out a few of the key reasons why adopting a more fully agile approach seems difficult, at least initially, for those of us working in agencies.

1. Agile asks more of your clients

When a team adopts Scrum everyone has to get used to a number of unfamiliar roles and rituals. Few team members have a steeper learning curve than the person designated as the product owner.

The product owner carries a lot of weight on their shoulders. They have to uphold the overall vision for the project. They are also meant to be the primary author of the project’s user stories (short atomic descriptions of project features which are testable and relate to a real business need). They should own this list of stories (called a backlog) and should be able to prioritise the order in which the stories are developed, to ensure that the project is delivering real value to the business early and often.

When a burst of work is completed (bursts of work in Scrum are called sprints), the product owner leads a review or show-and-tell session with the wider project stakeholders. The product owner needs to understand the work that has been completed, and must champion it to the business. Finally, and most importantly, the product owner is responsible for managing the feedback and requests from stakeholders in such a way that they don’t derail the project team’s agreed workload for any given sprint, without upsetting or offending any of the stakeholders – some of whom may outrank the product owner.

If you follow that spec, this is a job for a superhuman in any organisational context. And within the agency/client structure this superhuman needs to be client-side for the process to be at its most effective.

So your client, who in the past might have briefed a project to an agency team and then had the work presented back to them every few weeks, is now asked to be involved with the team on a daily basis; to fight on behalf of the team when new or difficult requests come in from senior figures within their organisation; and to present the agency’s work to their own colleagues after each sprint. It’s a big change if all that gets dropped into someone’s lap without warning.

There are several ways agencies can mitigate this issue. The ScrumAlliance suggests some alternative ways to structure the product owner role. The approach I have taken in the past is simply to start slow, and gradually move more of the product owner role over to the client side as and when they feel comfortable with it. If you’re working together long-term on a project, and you both see tangible improvements in the quality of the work after adopting an agile process, then your client is more likely to be open to further changes as the partnership progresses.

2. My client wants fixed costs, fixed deadlines and a fixed scope

I know. Mine too. Of course they do – it is the way that agencies and clients have agreed to work in digital and other creative service industries for a very long time. On both sides of the fence we’re used to thinking about projects in this way.

Of the three, fixing scope is the one that agile purists would rail hardest against. The more time we spend working on digital projects, the less sense it makes. James Archer, CEO of UI/UX design agency Forty puts it like this:


	For me, the Agile approach is really about acknowledging that disturbing truth that every project manager knows, but has trouble admitting. The truth that the project plan is wrong. Scope creep. Change orders. Shifting priorities. New directions. We act shocked and appalled when those things happen during our carefully planned project, even though they happen on every project ever.


Successful relationships require trust and honesty, and we shouldn’t be afraid of discussing this aspect of project management. If you do move away from a fixed scope of work, then the other two items (costs and timings) can be fixed – more or less. If you can get your clients to buy into this from a standing start then you are doing well. In fact you probably deserve a promotion. For most of us this is a continual discussion.

Anyway, as soon as you’ve made headway on the argument that it makes little or no sense to try and fix the scope of a digital project, you usually run into a related concern, which we’ll look at next.

3. Fear of uncontrolled costs

We all know that a dog is for life, not just for Christmas. At this time of year perhaps we should reiterate to everyone that digital products and services also need support and love once we have taken the decision to bring them into the world.

More organisations are realising that their investment in digital platforms should be viewed as an operational expenditure rather than a capital expenditure. But from time to time we will find ourselves working on projects for people who have a finite amount of money to invest in a product at a given point in time. When agencies start talking about these projects as rolling investments those responsible can understandably worry about their costs running out of control.

There’s another factor at play here. Agile, on the whole, prefers to derive a cost for services from the hours a team spends working on a project. In other industries this is referred to as charging for time and materials, and there seems to be an ingrained distrust in this approach among people in general. See, for example, the Citizens Advice Bureau’s “Top tips for employing a builder”:


	“Bear in mind that if you pay a daily rate, this makes it easier for a builder to string the work out and get more money so agree what you will do if the job takes longer than expected.”


It’s hard not to feel stung if you are in the builder’s shoes here, as we are when we’re talking about our role as an agency. But if you’ve ever haggled with a builder over time and materials, and also moaned about your clients misunderstanding agile methods, take a moment to reflect on the similarities from your client’s point of view.

Again, there are some things we can do to mitigate this issue. Some agencies put in place a service level agreement around their team’s velocity (an agile-related term related to how much work a team delivers in any given sprint) and this can help.

As the industry moves further towards a long-term approach to investment in digital I hope this fear will subside. But that shift in approach leads to the final concern I want to address.

4. Agency structures need shaking up

If you work for a company that has spent many years developing a business model around the waterfall process, you may have to break through many layers of entrenched thinking in order to establish new practices and effect organisational change.

There are consultancies that exist specifically to help agencies through their own agile transformation. One of these companies, AgencyAgile, provides a helpful list of common pitfalls. They emphasise the need to look at your whole agency’s structure, rather than simply encouraging project teams to adopt new workflows.


	Even awesomely run Agile projects can have a limited impact on the overall organization.


If you’re serious about changing the way your company approaches projects then try talking to people who sit outside the usual project delivery team. Speak to the finance department if you have one, and try to convince your senior management team if they’re not already on board. And definitely speak to your new business people, who go out there and win the projects you get to work on.

It’s these people who need to understand the potential business benefits of working in a new way, and also which of their existing habits and behaviours they might need to change to accommodate a new approach.

Otherwise you’ll find yourself with a team of designers, developers and project managers who are ready and waiting to deliver work in an iterative and collaborative way, but by the time they get hold of the project a cost has already been agreed, a deadline has been imposed, and a functional requirements document has been painstakingly put together. Nobody wins in this situation.

Conclusion

So where should we go from here? I certainly don’t have hard and fast answers – I’m not sure that they exist in a one-size-fits-all approach for agencies.

There are plenty of smart people thinking about this problem. It’s a hot topic right now. Earlier in the year a London-based meetup was established called Agile for Agencies. If you’re in the capital and want to discuss these issues with your peers it’s a great opportunity to do so.

I’ve mentioned James Archer and Forty already. Both James and Paul Boag have written in the last twelve months on this subject. They both come out on the side of the argument that suggests you adopt agile principles, but don’t have to worry about the rituals if they don’t fit in with your practices.

Personally, I think the rituals and the discipline mandated by an agile framework like Scrum can provide a great deal of value to your team, even it if is hard to implement within an agency culture that has traditionally structured its work and its services in another way.

In whatever way you figure out the details, when your teams collaborate with your clients rather than work for them at arm’s length, and when everyone prioritises frequent delivery, reflection and iteration over exhaustive scoping and planning, I believe you’ll see a tangible difference in the quality of the work that you create.",2014,Charlie Perrins,charlieperrins,2014-12-12T00:00:00+00:00,https://24ways.org/2014/is-agile-harder-for-agencies/,process
26,Integrating Contrast Checks in Your Web Workflow,"It’s nearly Christmas, which means you’ll be sure to find an overload of festive red and green decorating everything in sight—often in the ugliest ways possible. 

While I’m not here to battle holiday tackiness in today’s 24 ways, it might just be the perfect reminder to step back and consider how we can implement colour schemes in our websites and apps that are not only attractive, but also legible and accessible for folks with various types of visual disabilities.

I’ve been fortunate to work with Simply Accessible to redesign not just their website, but their entire brand. Although the new site won’t be launching until the new year, we’re excited to let you peek under the tree and share a few treats as a case study into how we tackled colour accessibility in our project workflow. Don’t worry—we won’t tell Santa!

Create a colour game plan

A common misconception about accessibility is that meeting compliance requirements hinders creativity and beautiful design—but we beg to differ. Unfortunately, like many company websites and internal projects, Simply Accessible has spent so much time helping others that they had not spent enough time helping themselves to show the world who they really are. This was the perfect opportunity for them to practise what they preached.

After plenty of research and brainstorming, we decided to evolve the existing Simply Accessible brand. Or, rather, salvage what we could. There was no established logo to carry into the new design (it was a stretch to even call it a wordmark), and the Helvetica typography across the site lacked any character. The only recognizable feature left to work with was colour. It was a challenge, for sure: the oranges looked murky and brown, and the blues looked way too corporate for a company like Simply Accessible. We knew we needed to inject a lot of personality.

The old Simply Accessible website and colour palette.

After an audit to round up every colour used throughout the site, we dug in deep and played around with some ideas to bring some new life to this palette. 

Choose effective colours

Whether you’re starting from scratch or evolving an existing brand, the first step to having an effective and legible palette begins with your colour choices. While we aren’t going to cover colour message and meaning in this article, it’s important to understand how to choose colours that can be used to create strong contrast—one of the most important ways to create hierarchy, focus, and legibility in your design.

There are a few methods of creating effective contrast.

Light and dark colours

The contrast that exists between light and dark colours is the most important attribute when creating effective contrast.

Try not to use colours that have a similar lightness next to each other in a design.



The red and green colours on the left share a similar lightness and don’t provide enough contrast on their own without making some adjustments. Removing colour and showing the relationship in greyscale reveals that the version on the right is much more effective. 

It’s important to remember that red and green colour pairs cause difficulty for the majority of colour-blind people, so they should be avoided wherever possible, especially when placed next to each other. 

Complementary contrast



Effective contrast can also be achieved by choosing complementary colours (other than red and green), that are opposite each other on a colour wheel.

These colour pairs generally work better than choosing adjacent hues on the wheel.

Cool and warm contrast

Contrast also exists between cool and warm colours on the colour wheel.

Imagine a colour wheel divided into cool colours like blues, purples, and greens, and compare them to warm colours like reds, oranges and yellows.



Choosing a dark shade of a cool colour, paired with a light tint of a warm colour will provide better contrast than two warm colours or two cool colours. 

Develop colour concepts

After much experimentation, we settled on a simple, two-colour palette of blue and orange, a cool-warm contrast colour scheme. We added swatches for call-to-action messaging in green, error messaging in red, and body copy and form fields in black and grey. Shades and tints of blue and orange were added to illustrations and other design elements for extra detail and interest.

First stab at a new palette.

We introduced the new palette for the first time on an internal project to test the waters before going full steam ahead with the website. It gave us plenty of time to get a feel for the new design before sharing it with the public.

Putting the test palette into practice with an internal report

It’s important to be open to changes in your palette as it might need to evolve throughout the design process. Don’t tell your client up front that this palette is set in stone. If you need to tweak the colour of a button later because of legibility issues, the last thing you want is your client pushing back because it’s different from what you promised.

As it happened, we did tweak the colours after the test run, and we even adjusted the logo—what looked great printed on paper looked a little too light on screens.

Consider how colours might be used

Don’t worry if you haven’t had the opportunity to test your palette in advance. As long as you have some well-considered options, you’ll be ready to think about how the colour might be used on the site or app. 

Obviously, in such early stages it’s unlikely that you’re going to know every element or feature that will appear on the site at launch time, or even which design elements could be introduced to the site later down the road. There are, of course, plenty of safe places to start.

For Simply Accessible, I quickly mocked up these examples in Illustrator to get a handle on the elements of a website where contrast and legibility matter the most: text colours and background colours. While it’s less important to consider the contrast of decorative elements that don’t convey essential information, it’s important for a reader to be able to discern elements like button shapes and empty form fields.

A basic list of possible colour combinations that I had in mind for the Simply Accessible website

Run initial tests

Once these elements were laid out, I manually plugged in the HTML colour code of each foreground colour and background colour on Lea Verou’s Contrast Checker. I added the results from each colour pair test to my document so we could see at a glance which colours needed adjustment or which colours wouldn’t work at all.

Note: Read more about colour accessibility and contrast requirements





As you can see, a few problems were revealed in this test. To meet the minimum AA compliance, we needed to slightly darken the green, blue, and orange background colours for text—an easy fix. A more complicated problem was apparent with the button colours. I had envisioned some buttons appearing over a blue background, but the contrast ratios were well under 3:1. Although there isn’t a guide in WCAG for contrast requirements of two non-text elements, the ISO and ANSI standard for visible contrast is 3:1, which is what we decided to aim for.

We also checked our colour combinations in Color Oracle, an app that simulates the most extreme forms of colour blindness. It confirmed that coloured buttons over blue backgrounds was simply not going to work. The contrast was much too low, especially for the more common deuteranopia and protanopia-type deficiencies.

How our proposed colour pairs could look to people with three types of colour blindness

Make adjustments if necessary



As a solution, we opted to change all buttons to white when used over dark coloured backgrounds. In addition to increasing contrast, it also gave more consistency to the button design across the site instead of introducing a lot of unnecessary colour variants.

Putting more work into getting compliant contrast ratios at this stage will make the rest of implementation and testing a breeze. When you’ve got those ratios looking good, it’s time to move on to implementation.

Implement colours in style guide and prototype

Once I was happy with my contrast checks, I created a basic style guide and added all the colour values from my colour exploration files, introduced more tints and shades, and added patterned backgrounds. I created examples of every panel style we were planning to use on the site, with sample text, links, and buttons—all with working hover states. Not only does this make it easier for the developer, it allows you to check in the browser for any further contrast issues.





Run a final contrast check

During the final stages of testing and before launch, it’s a good idea to do one more check for colour accessibility to ensure nothing’s been lost in translation from design to code. Unless you’ve introduced massive changes to the design in the prototype, it should be fairly easy to fix any issues that arise, particularly if you’ve stayed on top of updating any revisions in the style guide.

One of the more well-known evaluation tools, WAVE, is web-based and will work in any browser, but I love using Chrome’s Accessibility Tools. Not only are they built right in to the Inspector, but they’ll work if your site is password-protected or private, too.

Chrome’s Accessibility Tools audit feature shows that there are no immediate issues with colour contrast in our prototype 

The human touch

Finally, nothing beats a good round of user testing. Even evaluation tools have their flaws. Although they’re great at catching contrast errors for text and backgrounds, they aren’t going to be able to find errors in non-text elements, infographics, or objects placed next to each other where discernible contrast is important. 



Our final palette, compared with our initial ideas, was quite different, but we’re proud to say it’s not just compliant, but shows Simply Accessible’s true personality. Who knows, it may not be final at all—there are so many opportunities down the road to explore and expand it further.



Accessibility should never be an afterthought in a project. It’s not as simple as adding alt text to images, or running your site through a compliance checker at the last minute and assuming that a pass means everything is okay. Considering how colour will be used during every stage of your project will help avoid massive problems before launch, or worse, launching with serious issues. 

If you find yourself working on a personal project over the Christmas break, try integrating these checks into your workflow and make colour accessibility a part of your New Year’s resolutions.",2014,Geri Coady,gericoady,2014-12-22T00:00:00+00:00,https://24ways.org/2014/integrating-contrast-checks-in-your-web-workflow/,design
33,Five Ways to Animate Responsibly,"It’s been two years since I wrote about “Flashless Animation” on this very site. Since then, animation has steadily begun popping up on websites, from sleek app-like user interfaces to interactive magazine-like spreads. It’s an exciting time for web animation wonks, interaction developers, UXers, UI designers and a host of other acronyms! 

But in our rush to experiment with animation it seems that we’re having fewer conversations about whether or not we should use it, and more discussions about what we can do with it. We spend more time fretting over how to animate all the things at 60fps than we do devising ways to avoid incapacitating users with vestibular disorders.

I love web animation. I live it. And I make adorably silly things with it that have no place on a self-respecting production website. I know it can be abused. We’ve all made fun of Flash-turbation. But how quickly we forget the lessons we learned from that period of web design. Parallax scrolling effects may be the skip intro of this generation. Surely we have learned better in the sobering up period between Flash and the web animation API.

So here are five bits of advice we can use to pull back from the edge of animation abuse. With these thoughts in mind, we can make 2015 the year web animation came into its own. 

Animate deliberately

Sadly, animation is considered decorative by the bulk of the web development community. UI designers and interaction developers know better, of course. But when I’m teaching a workshop on animation for interaction, I know that my students face an uphill battle against decision makers who consider it nice to have, and tack it on at the end of a project, if at all. 

This stigma is hard to shake. But it starts with us using animation deliberately or not at all. Poorly considered, tacked-on animation will often cause more harm than good. Users may complain that it’s too slow or too fast, or that they have no idea what just happened.

When I was at Chrome Dev Summit this year, I had the privilege to speak with Roma Sha, the UX lead behind Polymer’s material design (with the wonderful animation documentation). I asked her what advice she’d give to people using animation and transitions in their own designs. She responded simply: animate deliberately. If you cannot afford to slow down to think about animation and make well-informed and well-articulated decisions on behalf of the user, it is better that you not attempt it at all. Animation takes energy to perform, and a bad animation is worse than none at all. 

It takes more than twelve principles

We always try to draw correlations between disparate things that spark our interest. Recently it feels like more and more people are putting the The Illusion of Life on their reading shelf next to Understanding Comics. These books give us so many useful insights from other industries. However, we should never mistake a website for a comic book or an animated feature film. Some of these concepts, while they help us see our work in a new light, can be more or less relevant to producing said work. 


The illusion of life from cento lodigiani on Vimeo.

I am specifically thinking of the twelve principles of animation put forth by Disney studio veterans in that great tome The Illusion of Life. These principles are very useful for making engaging, lifelike animation, like a ball bouncing or a squirrel scampering, or the physics behind how a lightbox should feel transitioning off a page. But they provide no direction at all for when or how something should be animated as part of a greater interactive experience, like how long a drop-down should take to fully extend or if a group of manipulable objects should be animated sequentially or as a whole.

The twelve principles are a great place to start, but we have so much more to learn. I’ve documented at least six more functions of interactive animation that apply to web and app design. When thinking about animation, we should consider why and how, not just what, the physics. Beautiful physics mean nothing if the animation is superfluous or confusing.

Useful and necessary, then beautiful

There is a Shaker saying: “Don’t make something unless it is both necessary and useful; but if it is both necessary and useful, don’t hesitate to make it beautiful.” When it comes to animation and the web, currently there is very little documentation about what makes it useful or necessary. We tend to focus more on the beautiful, the delightful, the aesthetic. And while aesthetics are important, they take a back seat to the user’s overall experience. 



The first time I saw the load screen for Pokemon Yellow on my Game Boy, I was enthralled.  By the sixth time, I was mashing the start button as soon as Game Freak’s logo hit the screen. What’s delightful and meaningful to us while working on a project is not always so for our users. And even when a purely delightful animation is favorably received, as with Pokemon Yellow’s adorable opening screen, too many repetitions of the cutest but ultimately useless animation, and users start to resent it as a hindrance.

 

If an animation doesn’t help the user in some way, by showing them where they are or how two elements on a page relate to each other, then it’s using up battery juice and processing cycles solely for the purpose of delight. Hardly the best use of resources.

Rather than animating solely for the sake of delight, we should first be able to articulate two things the animation does for the user. As an example, take this menu icon from Finethought.com (found via Use Your Interface). The menu icon does two things when clicked: 


	It gives the user feedback by animating, letting the user know its been clicked.
	It demonstrates its changed relationship to the page’s content by morphing into a close button.




Assuming we have two good reasons to animate something, there is no reason our third cannot be to delight the user. 

Go four times faster

There is a rule of thumb in the world of traditional animation which is applicable to web animation: however long you think your animation should last, take that time and halve it. Then halve it again! When we work on an animation for hours, our sense of time dilates. What seems fast to us is actually unbearably slow for most users. In fact, the most recent criticism from users of animated interfaces on websites seems to be, “It’s so slow!” A good animation is unobtrusive, and that often means running fast.

When getting your animations ready for prime time, reduce those durations to 25% of their original speed: a four-second fade out should be over in one. 

Install a kill switch

No matter how thoughtful and necessary an animation, there will be people who become physically sick from seeing it. For these people, we must add a way to turn off animations on the website. 

Fortunately, web designers are already thinking of ways to empower users to make their own decisions about how they experience the web. As an example, this site for the animated film Little from the Fish Shop allows users to turn off most of the parallax effects. While it doesn’t remove the animation entirely, this website does reduce the most nauseating of the animations. 	





Animation is a powerful tool in our web design arsenal. But we must take care: if we abuse animation it might get a bad reputation; if we underestimate it, it won’t be prioritized. But if we wield it thoughtfully, use it where it is both necessary and useful, and empower users to turn it off, animation is a tool that will help us build things that are easier to use and more delightful for years to come.

Let’s make 2015 the year web animation went to work for users.",2014,Rachel Nabors,rachelnabors,2014-12-14T00:00:00+00:00,https://24ways.org/2014/five-ways-to-animate-responsibly/,ux
40,Don’t Push Through the Pain,"In 2004, I lost my web career. In a single day, it was gone. I was in too much pain to use a keyboard, a Wacom tablet (I couldn’t even click the pen), or a trackball. Switching my mouse to use my left (non-dominant) hand only helped a bit; then that hand went, too. I tried all the easy-to-find equipment out there, except for expensive gizmos with foot pedals. I had tingling in my fingers—which, when I was away from the computer, would rhythmically move as if some other being controlled them. I worried about Parkinson’s because the movements were so dramatic. Pen on paper was painful. Finally, I discovered one day that I couldn’t even turn a doorknob.

The only highlight was that I couldn’t dust, scrub, or vacuum. We were forced to hire someone to come in once a week for an hour to whip through the house. You can imagine my disappointment. 

My injuries had gradually slithered into my life without notice. I’d occasionally have sore elbows, or my wrist might ache for a day, or my shoulders feel tight. But nothing to keyboard home about. That’s the critical bit of news. One day, you’re pretty fine. The next day, you don’t have your job—or any job that requires the use of your hands and wrists. 

I had to walk away from the computer for over four months—and partially for several months more. That’s right: no income. If I hadn’t found a gifted massage therapist, the right book of stretches, the equipment I should have been using all along, and learned how to pay attention to my body—even just a little bit more—I quite possibly wouldn’t be writing this article today. I wouldn’t be writing anything, anywhere. 

Most of us have heard of (and even claimed to have read all of) Mihaly Csikszentmihalyi, author of Flow: The Psychology of Optimal Experience, who describes the state of flow—the place our minds go when we are fully engaged and in our element. This lovely state of highly focused activity is deeply satisfying, often creative, and quite familiar to many of us on the web who just can’t quit until the copy sings or the code is untangled or we get our highest score yet in Angry Birds. Our minds may enter that flow, but too often as our brains take flight, all else recedes. And we leave something very important behind. 

Our bodies. 

My body wasn’t made to make the same minute movements thousands of times a day, most days of the year, for decades, and neither was yours. The wear and tear sneaks up on you, especially if you’re the obsessive perfectionist that we all pretend not to be. Oh? You’re not obsessed? I wasn’t like this all the time, but I remember sitting across from my husband, eating dinner, and I didn’t hear a word he said. I’d left my brain upstairs in my office, where it was wrestling in a death match with the box model or, God help us all, IE 5.2. I was a writer, too, and I was having my first inkling that I was a content strategist. Work was exciting. I could sit up late, in the flow, fingers flying at warp speed. I could sit until those wretched birds outside mocked me with their damn, cheerful “Hurray, it’s morning!” songs. Suddenly, while, say, washing dishes, the one magical phrase that captured the essence of a voice or idea would pop up, and I would have mowed down small animals and toddlers to get to my computer and hammer out that website or article, to capture that thought before it escaped. Note my use of the word hammer. Sound at all familiar? 

But where was my body during my work? Jaw jutting forward to see the screen, feet oddly positioned—and then left in place like chunks of marble—back unsupported, fingers pounding the keys, wrists and arms permanently twisted in unnatural angles that we thought were natural. And clicking. Clicking, clicking, clicking that mouse. Thumbing tiny keyboards on phones. A lethal little gesture for tiny little tendons. Though I was fine from, say 1997 to 2004, by the end of 2004 this behavior culminated in disaster. I had repetitive stress injuries, aka repetitive motion injuries. As the Apple site says, “A brief exposure to these conditions would not cause harm. But a prolonged exposure may, in some people, result in reduced ability to function.” I’ll say. 

I frantically turned to people on lists and forums. “Try a track ball.” Already did that. “Try a tablet.” Worse. One person wrote, “I still come here once in a while and can type a couple sentences, but I’ve permanently got thoracic outlet syndrome and I’ll never work again.” Oh, beauteous web, oh, long-distance friends, farewell.    

The Wrist Bone’s Connected to the Brain Bone

That variation on the old song tells part of the story. Most people (and many of their physicians) believe that tingling fingers and aching wrists MUST be carpel tunnel syndrome. Nope. If your neck juts forward, it tenses and stays tense the entire time you work in that position. Remember how your muscles felt after holding a landline phone with your neck tilted to one side for a long client meeting? Regrettable. Tensing your shoulders because your chair’s not designed properly puts you at risk for thoracic outlet syndrome, a career-killer if ever there was one. The nerves and tendons in your neck and shoulder refer down your arms, and muscles swell around nerves, causing pain and dysfunction. Your elbows have a tendon that is especially vulnerable to repetitive movements (think tennis elbow). Your wrists are performing something akin to a circus act with one thousand shows a day. 

So, all the fine tendons and ligaments in your fingers have problems that may not start at your wrists at all. Though some people truly do have carpal tunnel syndrome, my finger and wrist problems weren’t solved by heavily massaging my fingers (though, that was helpful, too) or my wrists. They were fixed by work on my neck, upper back, shoulders, arms, and elbows. This explains why many people have surgery for carpal tunnel syndrome and just months later say, “What?! How can I possibly have it again? I had an operation!” Well, fellow buckaroo, you may never have had carpel tunnel syndrome. You may have had—or perhaps will have—one long disaster area from your neck to your fingertips. 

How to Crawl Back 

Before trying extreme measures, you may be able to function again even if you feel hopeless. I managed to heal, and so have others, but I’ll always be at risk. 

As Jen Simmons, of The Web Ahead podcast and other projects told me, “It took a long time to injure myself. It took a long time to get back to where I was. My right arm between my elbow and wrist would start aching intermittently. Eventually, my arm even ached at night. I started each day with yesterday’s pain.” Simple measures, used consistently, helped her back. 

1. Massage therapy

I don’t remember what the rest of the world is like, but in Portland, Oregon, we have more than one massage therapy college. (Of course we do.) I saw a former teacher at the most respected school. This is not your “It was all so soothing. Why, I fell asleep!” massage. This is “Holy crap, he’s grinding his elbow into my armpit!“ massage therapy, with the emphasis on therapy. I owe him everything. Make sure you have someone who really knows what they’re doing. Get many referrals. Try a question, “Does my psoas muscle affect my back?” If they can’t answer it, flee. Regularly see the one you choose and after a while, depending on how injured you are, you may be able to taper off. 

2. Change your equipment

You may need to be hands-on with several pieces of equipment before you find the ones that don’t cause more pain. Many companies have restocking fees, charges to ship the equipment you want to return, and other retail atrocities. Always be sure to ask what the return policies are at any company before purchasing.

Mice 

You may have more success than I did with equipment such as the Wacom tablet. Mine came with a pen, and it hurt to repetitively click it. Trackballs are another option but, for many, they are better at prevention than recovery. But let’s get to the really effective stuff. One of the biggest sources of pain is using your mouse. One major reason is that your hand and wrist are in a perpetually unnatural position and you’re also moving your arm quite a bit. Each time you move the mouse, it is placing stress on your neck, shoulders and arms, because you need to lift them slightly in order to move the mouse and you need to angle your wrist. You may also be too injured to use the trackpad all the time, and this mouse, the vertical mouse is a dandy preventative measure, too. Shaking up your patterns is a wise move. I have long fingers, not especially thin, yet the small size works best for me. (They have larger choices available.) What?! A sideways mouse? Yep. All the weight of your hand will be resting on it in the handshake position. Your forearms aren’t constantly twisting over hill and dale. You aren’t using any muscles in your wrist or hand. They are relaxing. You’ll adapt in a day, and oh, oh, what a relief it is. 

Keyboards

I really liked doing business with the people at Kinesis-Ergo. (I’m not affiliated with them in any way.) They have the vertical mouse and a number of keyboards. The one that felt the most natural to me, and, once again, it only takes a day to adapt, is the Freestyle2 for the Mac. They have several options. I kept the keyboard halves attached to each other at first, and then spread them apart a little more. I recommend choosing one that slants and can separate. You can adjust the angle. For a little extra, they’ll make sure it’s all set up and ready to go for you. I’m guessing that some Googling will find you similar equipment, wherever you live. 

Warning: if you use the ergonomic keyboards, you may have fewer USB ports. The laptop will be too far away to see unless you find a satisfactory setup using a stand. This is the perfect excuse for purchasing a humongous display. 

You may not look cool while jetting coast to coast in your skinny jeans and what appears to be the old-time orthopedic shoe version of computing gear. But once you have rested and used many of these suggestions consistently, you may be able to use your laptop or other device in all its lovely sleekness during the trip. 

Other doohickies

The Kinesis site and The Human Solution have a wide selection of ergonomic products: standing desks, ergonomically correct chairs, and, yes, even things with foot pedals. Explore! 

3. Stop clicking, at least for a while

Use keyboard shortcuts, but use them slowly. This is not the time to show off your skillz. You’ll be sort of like a recovering alcoholic, in that you’ll be a recovering repetitive stress survivor for the rest of your life, once you really injure yourself. Always be vigilant. There’s also a bit of software sold by The Human Solution and other places, and it was my salvation. It’s called the McNib for Macs, and the Nib for PCs. (I’ve only used the McNib.) It’s for click-free mousing. I found it tricky to use when writing markup and code, but you may become quite adept at it. A little rectangle pops up on your screen, you mouse over it and choose, let’s say, “Double-click.” Until you change that choice, if you mouse over a link or anything else, it will double-click it for you. All you do is glide your mouse around. Awkward for a day or two, but you’ll pick it up quickly. Though you can use it all day for work, even if you just use this for browsing LOLcats or Gary Vaynerchuk’s YouTube videos, it will help you by giving your fingers a sweet break. 

But here’s the sad news. The developer who invented this died a few years ago. (Yes, I used to speak to him on the phone.) While it is for sale, it isn’t compatible with Mac OS X Lion or anything subsequent. PowerPC strikes again. His site is still up. Demos for use with older software can be downloaded free at his old site, or at The Human Solution. Perhaps an enterprising developer can invent something that would provide this help, without interfering with patents. Rumor has it among ergonomic retailers (yes, I’m like a police dog sniffing my way to a criminal once I head down a trail) that his company was purchased by a company in China, with no update in sight. 

4. Use built-in features

That little microphone icon that comes up alongside the keyboard on your iPhone allows you to speak your message instead of incessantly thumbing it. I believe it works in any program that uses the keyboard. It’s not Siri. She’s for other things, like having a personal relationship with an inanimate object. Apple even has a good section on ergonomics. You think I’m intense about this subject? To improve your repetitive stress, Apple doesn’t want you to use oral contraceptives, alcohol, or tobacco, to which I say, “Have as much sex, bacon, and chocolate as possible to make up for it.” 

Apple’s info even has illustrations of things like a faucet dripping into what is labeled a bucket full of “TRAUMA.” Sounds like upgrading to Yosemite, but I digress.  

5. Take breaks 

If it’s a game or other non-essential activity, take a break for a month. Fine, now that I’ve called games non-essential, I suppose you’ll all unfollow me on Twitter. 

6. Whether you are sore or not, do stretches throughout the day 

This is a big one. Really big. The best book on the subject of repetitive stress injuries is Conquering Carpal Tunnel Syndrome and Other Repetitive Strain Injuries: A Self-Care Program by Sharon J. Butler. Don’t worry, most of it is illustrations. Pretend it’s a graphic novel. 

I’m notorious for never reading instructions, and who on earth reads the introduction of a book, unless they wrote it? I wrote a book a long time ago, and I bet my house, husband, and life savings that my own parents never read the intro. Well, I did read the intro to this book, and you should, too. Stretching correctly, in a way that doesn’t further hurt you, that keeps you flexible if you aren’t injured, that actually heals you, calls for precision. Read and you’ll see. The key is to stretch just until you start to feel the stretch, even if that’s merely a tiny movement. Don’t force anything past that point. Kindly nurse yourself back to health, or nurture your still-healthy body by stretching. Over the following days, weeks, months, you’ll be moving well past that initial stretch point.   

The book is brimming with examples. You only have to pick a few stretches, if this is too much to handle. Do it every single day. I can tell you some of the best ones for me, but it depends on the person. You’ll also discover in Butler’s book that areas that you think are the problem are sometimes actually adjacent to the muscle or tendon that is the source of the problem. Add a few stretches or two for that area, too.  

But please follow the instructions in the introduction. If you overdo it, or perform some other crazy-ass hijinks, as I would be tempted to do, I am not responsible for your outcome. I give you fair warning that I am not a healthcare provider. I’m just telling you as a friend, an untrained one, at that, who has been through this experience. 

7. Follow good habits

Develop habits like drinking lots of water (which helps with lactic acid buildup in muscles), looking away from the computer for twenty seconds every twenty to thirty minutes, eating right, and probably doing everything else your mother told you to do. Maybe this is a good time to bring up flossing your teeth, and going outside to play instead of watching TV. As your mom would say, “It’s a beautiful day outside, what are you kids doing in here?” 

8. Speak instead of writing, if you can 

Amber Simmons, who is very smart and funny, once tweeted in front of the whole world that, “@carywood is a Skype whore.” I was always asking people on Twitter if we could Skype instead of using iChat or exchanging emails. (I prefer the audio version so I don’t have to, you know, do something drastic like comb my hair.) Keyboarding is tough on hands, whether you notice it or not at the time, and when doing rapid-fire back-and-forthing with people, you tend to speed up your typing and not take any breaks. This is a hand-killer. Voice chats have made such a difference for me that I am still a rabid Skype whore. Wait, did I say that out loud? 

Speak your text or emails, using Dragon Dictate or other software. In about 2005, accessibility and user experience design expert, Derek Featherstone, in Canada, and I, at home, chatted over the internet, each of us using a different voice-to-text program. The programs made so many mistakes communicating with each other that we began that sort of endless, tearful laughing that makes you think someone may need to call an ambulance. This type of software has improved quite a bit over the years, thank goodness. Lack of accessibility of any kind isn’t funny to Derek or me or to anyone who can’t use the web without pain. 

9. Watch your position 

For example, if you lift up your arms to use the computer, or stare down at your laptop, you’ll need to rearrange your equipment. The internet has a lot of information about ideal ergonomic work areas. Please use a keyboard drawer. Be sure to measure the height carefully so that even a tented keyboard, like the one I recommend, will fit. I also recommend getting the version of the Freestyle with palm supports. Just these two measures did much to help both Jen Simmons and me. 

10. If you need to take anti-inflammatories, stop working

If you are all drugged up on ibuprofen, and pounding and clicking like mad, your body will not know when you are tired or injuring yourself. I don’t recommend taking these while using your computing devices. Perhaps just take it at night, though I’m not a fan of that category of medications. Check with your healthcare provider. At least ibuprofen is an anti-inflammatory, which may help you. In contrast, acetaminophen (paracetamol) only makes your body think it’s not in pain. Ice is great, as is switching back and forth between ice and heat. But again, if you need ice and ibuprofen you really need to take a major break. 

11. Don’t forget the rest of your body

I’ve zeroed in on my personal area of knowledge and experience, but you may be setting yourself up for problems in other areas of your body. There’s what is known to bad writers as “a veritable cornucopia” of information on the web about how to help the rest of your body. A wee bit of research on the web and you’ll discover simple exercises and stretches for the rest of your potential catastrophic areas: your upper back, your lower back, your legs, ankles, and eyes. Do gentle stretches, three or four times a day, rather than powering your way through. Ease into new equipment such as standing desks. Stretch those newly challenged areas until your body adapts. Pay attention to your body, even though I too often forget mine. 

12. Remember the children

Kids are using equipment to play highly addictive games or to explore amazing software, and if these call for repetitive motions, children are being set up for future injuries. They’ll grab hold of something, as parents out there know, and play it 3,742 times. That afternoon. Perhaps by the time they are adults, everything will just be holograms and mind-reading, but adult fingers and hands are used for most things in life, not just computing devices and phones with keyboards sized for baby chipmunks. 

I’ll be watching you

Quickly now, while I (possibly) have your attention. Don’t move a muscle. Is your neck tense? Are you unconsciously lifting your shoulders up? How long since you stopped staring at the screen? How bright is your screen? Are you slumping (c’mon now, ‘fess up) and inviting sciatica problems? Do you have to turn your hands at an angle relative to your wrist in order to type? Uh-oh. That’s a bad one. Your hands, wrists, and forearms should be one straight line while keyboarding. Future you is begging you to change your ways. Don’t let your #ThrowbackThursday in 2020 say, “Here’s a photo from when I used to be able to do so many wonderful things that I can’t do now.” And, whatever you do, don’t try for even a nanosecond to push through the pain, or the next thing you know, you’ll be an unpaid extra in The Expendables 7.",2014,Carolyn Wood,carolynwood,2014-12-06T00:00:00+00:00,https://24ways.org/2014/dont-push-through-the-pain/,business
47,Developing Robust Deployment Procedures,"Once you have developed your site, how do you make it live on your web hosting? For many years the answer was to log on to your server and upload the files via FTP. Over time most hosts and FTP clients began to support SFTP, ensuring your files were transmitted over a secure connection. The process of deploying a site however remained the same.

There are issues with deploying a site in this way. You are essentially transferring files one by one to the server without any real management of that transfer. If the transfer fails for some reason, you may end up with a site that is only half updated. It can then be really difficult to work out what hasn’t been replaced or added, especially where you are updating an existing site. If you are updating some third-party software your update may include files that should be removed, but that may not be obvious to you and you risk leaving outdated files littering your file system. Updating using (S)FTP is a fragile process that leaves you open to problems caused by both connectivity and human error. Is there a better way to do this?

You’ll be glad to know that there is. A modern professional deployment workflow should have you moving away from fragile manual file transfers to deployments linked to code committed into source control.

The benefits of good practice

You may never have experienced any major issues while uploading files over FTP, and good FTP clients can help. However, there are other benefits to moving to modern deployment practices.

No surprises when you launch

If you are deploying in the way I suggest in this article you should have no surprises when you launch because the code you committed from your local environment should be the same code you deploy – and to staging if you have a staging server. A missing vital file won’t cause things to start throwing errors on updating the live site.

Being able to work collaboratively

Source control and good deployment practice makes working with your clients and other developers easy. Deploying first to a staging server means you can show your client updates and then push them live. If you subcontract some part of the work, you can give your subcontractor the ability to deploy to staging, leaving you with the final push to launch, once you know you are happy with the work.

Having a proper backup of site files with access to them from anywhere

The process I will outline requires the use of hosted, external source control. This gives you a backup of your latest commit and the ability to clone those files and start working on them from any machine, wherever you are.

Being able to jump back into a site quickly when the client wants a few changes

When doing client work it is common for some work to be handed over, then several months might go by without you needing to update the site. If you don’t have a good process in place, just getting back to work on it may take several hours for what could be only a few hours of work in itself. A solid method for getting your local copy up to date and deploying your changes live can cut that set-up time down to a few minutes.

The tool chain

In the rest of this article I assume that your current practice is to deploy your files over (S)FTP, using an FTP client. You would like to move to a more robust method of deployment, but without blowing apart your workflow and spending all Christmas trying to put it back together again. Therefore I’m selecting the most straightforward tools to get you from A to B.

Source control

Perhaps you already use some kind of source control for your sites. Today that is likely to be Git but you might also use Subversion or Mercurial. If you are not using any source control at all then I would suggest you choose Git, and that is what I will be working with in this article.

When you work with Git, you always have a local repository. This is where your changes are committed. You also have the option to push those changes to a remote repository; for example, GitHub. You may well have come across GitHub as somewhere you can go to download open source code. However, you can also set up private repositories for sites whose code you don’t want to make publicly accessible.

A hosted Git repository gives you somewhere to push your commits to and deploy from, so it’s a crucial part of our tool chain.

A deployment service

Once you have your files pushed to a remote repository, you then need a way to deploy them to your staging environment and live server. This is the job of a deployment service.

This service will connect securely to your hosting, and either automatically (or on the click of a button) transfer files from your Git commit to the hosting server. If files need removing, the service should also do this too, so you can be absolutely sure that your various environments are the same.

Tools to choose from

What follows are not exhaustive lists, but any of these should allow you to deploy your sites without FTP.

Hosted Git repositories


	GitHub
	Beanstalk
	Bitbucket


Standalone deployment tools


	Deploy
	dploy.io
	FTPloy


I’ve listed Beanstalk as a hosted Git repository, though it also includes a bundled deployment tool. Dploy.io is a standalone version of that tool just for deployment. In this tutorial I have chosen two separate services to show how everything fits together, and because you may already be using source control. If you are setting up all of this for the first time then using Beanstalk saves having two accounts – and I can personally recommend them.

Putting it all together

The steps we are going to work through are:


	Getting your local site into a local Git repository
	Pushing the files to a hosted repository
	Connecting a deployment tool to your web hosting
	Setting up a deployment


Get your local site into a local Git repository

Download and install Git for your operating system.

Open up a Terminal window and tell Git your name using the following command (use the name you will set up on your hosted repository).

> git config --global user.name ""YOUR NAME""


Use the next command to give Git your email address. This should be the address that you will use to sign up for your remote repository.

> git config --global user.email ""YOUR EMAIL ADDRESS""


Staying in the command line, change to the directory where you keep your site files. If your files are in /Users/rachel/Sites/mynicewebite you would type:

> cd /Users/rachel/Sites/mynicewebsite


The next command tells Git that we want to create a new Git repository here.

> git init


We then add our files:

> git add .


Then commit the files:

> git commit -m “Adding initial files”


The bit in quotes after -m is a message describing what you are doing with this commit. It’s important to add something useful here to remind yourself later why you made the changes included in the commit.

Your local files are now in a Git repository! However, everything should be just the same as before in terms of working on the files or viewing them in a local web server. The only difference is that you can add and commit changes to this local repository.

Want to know more about Git? There are some excellent resources in a range of formats here.

Setting up a hosted Git repository

I’m going to use Atlassian Bitbucket for my first example as they offer a free hosted and private repository.

Create an account on Bitbucket. Then create a new empty repository and give it a name that will identify the repository easily.

Click Getting Started and under Command Line select “I have an existing project”. This will give you a set of instructions to run on the command line. The first instruction is just to change into your working directory as we did before. We then add a remote repository, and run two commands to push everything up to Bitbucket.

cd /path/to/my/repo
git remote add origin https://myuser@bitbucket.org/myname/24ways-tutorial.git
git push -u origin --all 
git push -u origin --tags 


When you run the push command you will be asked for the password that you set for Bitbucket. Having entered that, you should be able to view the files of your site on Bitbucket by selecting the navigation option Source in the sidebar.

You will also be able to see commits. When we initially committed our files locally we added the message “Adding initial files”. If you select Commits from the sidebar you’ll see we have one commit, with the message we set locally. You can imagine how useful this becomes when you can look back and see why you made certain changes to a project that perhaps you haven’t worked on for six months.

Before working on your site locally you should run:

> git pull


in your working directory to make sure you have all of the most up-to-date files. This is especially important if someone else might work on them, or you just use multiple machines.

You then make your changes and add any changed or modified files, for example:

> git add index.php


Commit the change locally:

> git commit -m “updated the homepage”


Then push it to Bitbucket:

> git push origin master


If you want to work on your files on a different computer you clone them using the following command:

> git clone https://myuser@bitbucket.org/myname/24ways-tutorial.git


You then have a copy of your files that is already a Git repository with the Bitbucket repository set up as a remote, so you are all ready to start work.

Connecting a deployment tool to your repository and web hosting

The next step is deploying files. I have chosen to use a deployment tool called Deploy as it has support for Bitbucket. It does have a monthly charge – but offers a free account for open source projects.

Sign up for your account then log in and create your first project. Select Create an empty project. Under Configure Repository Details choose Bitbucket and enter your username and password.

If Deploy can connect, it will show you your list of projects. Select the one you want.

The next screen is Add New Server and here you need to configure the server that you want to deploy to. You might set up more than one server per project. In an ideal world you would deploy to a staging server for your client preview changes and then deploy once everything is signed off. For now I’ll assume you just want to set up your live site.

Give the server a name; I usually use Production for the live web server. Then choose the protocol to connect with. Unless your host really does not support SFTP (which is pretty rare) I would choose that instead of FTP.

You now add the same details your host gave you to log in with your SFTP client, including the username and password. The Path on server should be where your files are on the server. When you log in with an SFTP client and you get put in the directory above public_html then you should just be able to add public_html here.

Once your server is configured you can deploy. Click Deploy now and choose the server you just set up. Then choose the last commit (which will probably be selected for you) and click Preview deployment. You will then get a preview of which files will change if you run the deployment: the files that will be added and any that will be removed. At the very top of that screen you should see the commit message you entered right back when you initially committed your files locally.

If all looks good, run the deployment.

You have taken the first steps to a more consistent and robust way of deploying your websites. It might seem like quite a few steps at first, but you will very soon come to realise how much easier deploying a live site is through this process.

Your new procedure step by step


	Edit your files locally as before, testing them through a web server on your own computer.
	Commit your changes to your local Git repository.
	Push changes to the remote repository.
	Log into the deployment service.
	Hit the Deploy now button.
	Preview the changes.
	Run the deployment and then check your live site.


Taking it further

I have tried to keep things simple in this article because so often, once you start to improve processes, it is easy to get bogged down in all the possible complexities. If you move from deploying with an FTP client to working in the way I have outlined above, you’ve taken a great step forward in creating more robust processes. You can continue to improve your procedures from this point.

Staging servers for client preview

When we added our server we could have added an additional server to use as a staging server for clients to preview their site on. This is a great use of a cheap VPS server, for example. You can set each client up with a subdomain – clientname.yourcompany.com – and this becomes the place where they can view changes before you deploy them.

In that case you might deploy to the staging server, let the client check it out and then go back and deploy the same commit to the live server.

Using Git branches

As you become more familiar with using Git, and especially if you start working with other people, you might need to start developing using branches. You can then have a staging branch that deploys to staging and a production branch that is always a snapshot of what has been pushed to production. This guide from Beanstalk explains how this works.

Automatic deployment to staging

I wouldn’t suggest doing automatic deployment to the live site. It’s worth having someone on hand hitting the button and checking that everything worked nicely. If you have configured a staging server, however, you can set it up to deploy the changes each time a commit is pushed to it.

If you use Bitbucket and Deploy you would create a deployment hook on Bitbucket to post to a URL on Deploy when a push happens to deploy the code. This can save you a few steps when you are just testing out changes. Even if you have made lots of changes to the staging deployment, the commit that you push live will include them all, so you can do that manually once you are happy with how things look in staging.

31,Dealing with Emergencies in Git,"The stockings were hung by the chimney with care,
In hopes that version control soon would be there.

This summer I moved to the UK with my partner, and the onslaught of the Christmas holiday season began around the end of October (October!). It does mean that I’ve had more than a fair amount of time to come up with horrible Git analogies for this article. Analogies, metaphors, and comparisons help the learner hook into existing mental models about how a system works. They only help, however, if the learner has enough familiarity with the topic at hand to make the connection between the old and new information.

Let’s start by painting an updated version of Clement Clarke Moore’s Christmas living room. Empty stockings are hung up next to the fireplace, waiting for Saint Nicholas to come down the chimney and fill them with small treats. Holiday treats are scattered about. A bowl of mixed nuts, the holiday nutcracker, and a few clementines. A string of coloured lights winds its way up an evergreen.

Perhaps a few of these images are familiar, or maybe they’re just settings you’ve seen in a movie. It doesn’t really matter what the living room looks like though. The important thing is to ground yourself in your own experiences before tackling a new subject. Instead of trying to brute-force your way into new information, as an adult learner constantly ask yourself: ‘What is this like? What does this remind me of? What do I already know that I can use to map out this new territory?’ It’s okay if the map isn’t perfect. As you refine your understanding of a new topic, you’ll outgrow the initial metaphors, analogies, and comparisons.

With apologies to Mr. Moore, let’s give it a try.

Getting Interrupted in Git

When on the roof there arose such a clatter!

You’re happily working on your software project when all of a sudden there are freaking reindeer on the roof! Whatever you’ve been working on is going to need to wait while you investigate the commotion.

If you’ve got even a little bit of experience working with Git, you know that you cannot simply change what you’re working on in times of emergency. If you’ve been doing work, you have a dirty working directory and you cannot change branches, or push your work to a remote repository while in this state.

Up to this point, you’ve probably dealt with emergencies by making a somewhat useless commit with a message something to the effect of ‘switching branches for a sec’. This isn’t exactly helpful to future you, as commits should really contain whole ideas of completed work. If you get interrupted, especially if there are reindeer on the roof, the chances are very high that you weren’t finished with what you were working on.

You don’t need to make useless commits though. Instead, you can use the stash command. This command allows you to temporarily set aside all of your changes so that you can come back to them later. In this sense, stash is like setting your book down on the side table (or pushing the cat off your lap) so you can go investigate the noise on the roof. You aren’t putting your book away though, you’re just putting it down for a moment so you can come back and find it exactly the way it was when you put it down.

Let’s say you’ve been working in the branch waiting-for-st-nicholas, and now you need to temporarily set aside your changes to see what the noise was on the roof:

$ git stash

After running this command, all uncommitted work will be temporarily removed from your working directory, and you will be returned to whatever state you were in the last time you committed your work.

With the book safely on the side table, and the cat safely off your lap, you are now free to investigate the noise on the roof. It turns out it’s not reindeer after all, but just your boss who thought they’d help out by writing some code on the project you’ve been working on. Bless. Rolling your eyes, you agree to take a look and see what kind of mischief your boss has gotten themselves into this time.

You fetch an updated list of branches from the remote repository, locate the branch your boss had been working on, and checkout a local copy:

$ git fetch
$ git branch -r
$ git checkout -b helpful-boss-branch origin/helpful-boss-branch

You are now in a local copy of the branch where you are free to look around, and figure out exactly what’s going on.

You sigh audibly and say, ‘Okay. Tell me what was happening when you first realised you’d gotten into a mess’ as you look through the log messages for the branch.

$ git log --oneline
$ git log

By using the log command you will be able to review the history of the branch and find out the moment right before your boss ended up stuck on your roof.

You may also want to compare the work your boss has done to the main branch for your project. For this article, we’ll assume the main branch is named master.

$ git diff master

Looking through the commits, you may be able to see that things started out okay but then took a turn for the worse.

Checking out a single commit

Using commands you’re already familiar with, you can rewind through history and take a look at the state of the code at any moment in time by checking out a single commit, just like you would a branch.

Using the log command, locate the unique identifier (commit hash) of the commit you want to investigate. For example, let’s say the unique identifier you want to checkout is 25f6d7f.

$ git checkout 25f6d7f

Note: checking out '25f6d7f'.

You are in 'detached HEAD' state. You can look around,
make experimental changes and commit them, and you can
discard any commits you make in this state without
impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may do so (now or later) by using @-b@ with the checkout command again. Example:

$ git checkout -b new_branch_name

HEAD is now at 25f6d7f... Removed first paragraph.

This is usually where people start to panic. Your boss screwed something up, and now your HEAD is detached. Under normal circumstances, these words would be a very good reason to panic.

Take a deep breath. Nothing bad is going to happen. Being in a detached HEAD state just means you’ve temporarily disconnected from a known chain of events. In other words, you’re currently looking at the middle of a story (or branch) about what happened – and you’re not at the endpoint for this particular story.

Git allows you to view the history of your repository as a timeline (technically it’s a directed acyclic graph). When you make commits which are not associated with a branch, they are essentially inaccessible once you return to a known branch. If you make commits while you’re in a detached HEAD state, and then try to return to a known branch, Git will give you a warning and tell you how to save your work.

$ git checkout master

Warning: you are leaving 1 commit behind, not connected to
any of your branches:

  7a85788 Your witty holiday commit message.

If you want to keep them by creating a new branch, this may be a good time to do so with:

$ git branch new_branch_name 7a85788

Switched to branch 'master'
Your branch is up-to-date with 'origin/master'.

So, if you want to save the commits you’ve made while in a detached HEAD state, you simply need to put them on a new branch.

$ git branch saved-headless-commits 7a85788

With this trick under your belt, you can jingle around in history as much as you’d like. It’s not like sliding around on a timeline though. When you checkout a specific commit, you will only have access to the history from that point backwards in time. If you want to move forward in history, you’ll need to move back to the branch tip by checking out the branch again.

$ git checkout helpful-boss-branch

You’re now back to the present. Your HEAD is now pointing to the endpoint of a known branch, and so it is no longer detached. Any changes you made while on your adventure are safely stored in a new branch, assuming you’ve followed the instructions Git gave you. That wasn’t so scary after all, now, was it?

Back to our reindeer problem.

If your boss is anything like the bosses I’ve worked with, chances are very good that at least some of their work is worth salvaging. Depending on how your repository is structured, you’ll want to capture the good work using one of several different methods.

Back in the living room, we’ll use our bowl of nuts to illustrate how you can rescue a tiny bit of work.

Saving just one commit

About that bowl of nuts. If you’re like me, you probably had some favourite kinds of nuts from an assorted collection. Walnuts were generally the most satisfying to crack open. So, instead of taking the entire bowl of nuts and dumping it into a stocking (merging the stocking and the bowl of nuts), we’re just going to pick out one nut from the bowl. In Git terms, we’re going to cherry-pick a commit and save it to another branch.

First, checkout the main branch for your development work. From this branch, create a new branch where you can copy the changes into.

$ git checkout master
$ git checkout -b rescue-the-boss

From your boss’s branch, helpful-boss-branch locate the commit you want to keep.

$ git log --oneline helpful-boss-branch

Let’s say the commit ID you want to keep is e08740b. From your rescue branch, use the command cherry-pick to copy the changes into your current branch.

$ git cherry-pick e08740b

If you review the history of your current branch again, you will see you now also have the changes made in the commit in your boss’s branch.

At this point you might need to make a few additional fixes to help your boss out. (You’re angling for a bonus out of all this. Go the extra mile.) Once you’ve made your additional changes, you’ll need to add that work to the branch as well.

$ git add [filename(s)]
$ git commit -m ""Building on boss's work to improve feature X.""

Go ahead and test everything, and make sure it’s perfect. You don’t want to introduce your own mistakes during the rescue mission!

Uploading the fixed branch

The next step is to upload the new branch to the remote repository so that your boss can download it and give you a huge bonus for helping you fix their branch.

$ git push -u origin rescue-the-boss

Cleaning up and getting back to work

With your boss rescued, and your bonus secured, you can now delete the local temporary branches.

$ git branch --delete rescue-the-boss
$ git branch --delete helpful-boss-branch

And settle back into your chair to wait for Saint Nicholas with your book, your branch, and possibly your cat.

$ git checkout waiting-for-st-nicholas
$ git stash pop

Your working directory has been returned to exactly the same state you were in at the beginning of the article.

Having fun with analogies

I’ve had a bit of fun with analogies in this article. But sometimes those little twists on ideas can really help someone pick up a new idea (git stash: it’s like when Christmas comes around and everyone throws their fashion sense out the window and puts on a reindeer sweater for the holiday party; or git bisect: it’s like trying to find that one broken light on the string of Christmas lights). It doesn’t matter if the analogy isn’t perfect. It’s just a way to give someone a temporary hook into a concept in a way that makes the concept accessible while the learner becomes comfortable with it. As the learner’s comfort increases, the analogies can drop away, making room for the technically correct definition of how something works.

Or, if you’re like me, you can choose to never grow old and just keep mucking about in the analogies. I’d argue it’s a lot more fun to play with a string of Christmas lights and some holiday cheer than a directed acyclic graph anyway.",2014,Emma Jane Westby,emmajanewestby,2014-12-02T00:00:00+00:00,https://24ways.org/2014/dealing-with-emergencies-in-git/,code
43,Content Production Planning,"While everyone agrees that getting the content of a website right is vital to its success, unless you’re lucky enough to have an experienced editor or content strategist on board, planning content production often seems to fall through the cracks. One reason is that, for most of the team, it feels like someone else’s problem. Not necessarily a specific person’s problem. Just someone else’s. It’s only when everyone starts urgently asking when the content is going to be ready, that it becomes clear the answer is, “Not as soon as we’d like it”.

The good news is that there are some quick and simple things you can do, even if you’re not the official content person on a project, to get everyone on the same content planning page. 

Content production planning boils down to answering three deceptively simple questions:


	What content do you need?
	How much of it do you need?
	Who’s going to make it?


Even if it’s not your job to come up with the answers, by asking these questions early enough and agreeing who is going to come up with the answers, you’ll be a long way towards avoiding the last-minute content problems which so often plague projects.

How much content do we need?

People tend to underestimate two crucial things about content: how much content they need, and how long that content takes to produce.

When I ask someone how big their website is – how many pages it contains – I usually double or triple the answer I get. That’s because almost everyone’s mental model of their website greatly underestimates its true size. You can see the problem for yourself if you look at a site map. Site maps are great at representing a mental model of a website. But because they’re a deliberate simplification they naturally lead us to underestimate how much content is involved in populating them.

Several years ago I was asked to help a client create a new microsite (their word) which they wanted ready in two weeks for a conference they were attending. Here’s the site map they had in mind. At first glance it looks like a pretty small website. Maybe twenty to thirty pages?



That’s what the client thought.

But see those boxes which are multiple boxes stacked on top of one another, for product categories, descriptions and supporting material? They’re known as page stacks, and page stacks are the content strategy equivalent of Here Be Dragons. 



Say we have:


	five product categories
	each with five products
	which all have two or three supporting documents


Those are still fairly small numbers. But small numbers multiplied by other small numbers tend to lead to big numbers.



5 categories = 5 category descriptions

plus

5 categories × 5 products each = 25 product descriptions

plus

25 products × 2.5 (average) supporting documents = 63 supporting documents

equals

93 pages



Suddenly our twenty- or thirty-page website is running towards one hundred.

That’s probably enough to get most project teams to sit up and take notice. But there’s still the danger of underestimating how long it’s going to take to create the content. After all, assuming the supporting documents already exist in some form, there are only about twenty-five to thirty pages of new copy to write.

How much work is it?

Again, we have the problem that small numbers when multiplied by other small numbers tend to lead to big numbers. Let’s make a rough guess that it’ll take four hours to write each product category and description page we need. That feels a little conservative if we’re writing stuff from scratch, but assuming the person doing it already knows the products fairly well it’s not unreasonable.



30 pages × 4 hours each = 120 hours

120 hours ÷ 7.5 working hours a day = 16 days



Ouch.

At this point it’s pretty clear we’re not getting this site launched in two weeks. 

The goal is the conversation

By breaking down the site into its content components, and putting some rough estimates on how long each might take to produce, the client instantly realised that there was no way they would be ready to launch it in two weeks. Although we still didn’t know exactly when it would be ready, getting to that realisation right at the start of the project was a major win for everybody. Without it, the design agency would have bust a gut to get the design, front-end and CMS all done in double-quick time, only to find it was all for nothing as barely half the content was ready. As it was, an early discussion about content, albeit a brief one, bought everyone time to tackle the project properly, without pulling any long nights or working weekends.

If you haven’t been able to get people to discuss content plans for the project, these kinds of rough estimates should give you enough evidence to get everyone to start taking it seriously. Your goal is to get everyone on the project to a place where they are ready to talk in detail about who is going to create this content, and how long it’s really going to take them, and to get to those conversations before lack of content becomes a problem.

Be careful though. It’s best to talk in ranges and round numbers when your estimates are this uncertain. And watch those multipliers. Given small numbers multiplied by other small numbers lead to big numbers, changing just one number can greatly change the overall estimate. I like to run a couple of different scenarios to check what things look like if I’ve under- or overestimated either how many pages we’re going to need, or how long they’re going to take to create. For example:



Top end: 30 pages × 5 hours = 150 hours, or 20 days

Bottom end: 25 pages × 4 hours = 100 hours, or 13.3 days



So rather than say, “I estimate the content will take around sixteen days to produce”, I’m going to say, “I think the content will take about three to four weeks to produce”. Even with qualifiers like estimate and around, sixteen days sounds too precise. Whereas three to four weeks instantly conveys that this is just a rough figure.

Who’s going to make it?

So, people tend to underestimate two crucial things about content: how much content they need, and how long content takes to write. At this stage, you’re still in danger of the latter, because it’s tempting to simply estimate how much time content takes to write (or record, if we’re talking audio or visual content), and overlook all the other work that needs to goes on around it. 

Take 24 ways as an example. In terms of our three deceptively simple questions: what is practical articles about web design; how many is twenty-four, one for each day of Advent; and who are experts working on the web, one to write each article. 

But there’s another who you might not have considered. 

Someone needs to select those authors in the first place, make sure they deliver their articles on time (and find someone to replace them if they don’t), review drafts, copy-edit and proofread final versions, upload them to the site, promote them, keep an eye on the comments and make sure there are still presents under the tree on Christmas morning.

Even if each of those tasks only takes an hour or so, it then needs multiplying by twenty-four (except the presents, obviously). And as we’ve already seen, small numbers multiplied by small numbers quickly turn into much bigger numbers. Just a few hours per article, when multiplied by twenty-four articles, easily multiplies up to days or even weeks of effort.

To get a more accurate estimate of how long the different kinds of content are going to take, you need to break down the content production work into its constituent stages, starting with planning, moving on through the main work of creation, to reviewing, approvals and finally publishing. You need to think about who needs to be involved at each step, and how much time they’ll need to do their bit. 

Taken together, these things make up your content workflow. The workflow will be different for each organisation, but might look something like this:


	Eddie the web editor will work out the key messages and objectives for each page, and agree them with Mo the marketing director.
	Eddie will then get Cal, the copywriter, to write the first draft.
	As part of that, Cal will interview Sam the subject expert to understand the intricacies of the subject and get all the facts straight.
	Once Cal’s done the first draft, it’ll go to Sam to check for accuracy, while Eddie reviews it for style and message.
	Once Cal has incorporated their feedback it’s time to get Mo to have a look at the final draft.
	If Mo’s happy, it’ll get a final proofread, be uploaded to the CMS, and Mo will give the final sign-off and release it for publishing.


You can plot this on a table, with the stages of the content production process down the side, and the key roles or personnel along with top. Then the team can estimate how much time they think each of them needs at each stage.

You can then bring out your calculator again, and come up with some more big scary numbers showing how much time it’s going to take for the whole team to get all the content needed not just written, but also planned, reviewed, approved and published.

With an experienced team you can run this exercise as a group workshop and get some fairly accurate estimates pretty quickly. If this is all a bit new to you, check out Gather Content’s Content Production Planning for Agencies ebook for a useful guide to common content roles, ballpark estimates for how much time each one needs on a typical piece of content, and how to run a process and estimating workshop to dig into them in more detail. 

On a small team, one person might play many roles, but you should still sanity-check your estimates by breaking down the process and putting a rough estimate on each stage. With only a couple of people involved, it’s even easier to only include the core activity like writing or recording in your estimates, and forget to allow time for the planning, reviewing, proofreading, publishing and promoting you’ll still need to do. And even in a team of one, if at all possible you should find at least one other person to act as a second pair of eyes, and give anything you produce a quick once-over and proofread before it’s published.

Depending on the kind of content you’re making, you should also consider what will happen after it’s published. The full content life cycle should include promotion, monitoring and regular reviews to make sure content stays accurate and up to date. Making sure you have the time and resources available to do all those things for each piece of content is essential for creating a sustainable content programme.

The proof of the pudding

Even after digging into workflow and getting the whole team involved in estimating, you’re still largely in the realm of the guesstimate. The good news, though, is that you can quite quickly start finding out if your guesstimates are right or not. As soon as you can, pilot the production process with some real content. This is a double-win: you start finding out how long it really takes to produce all this fab new content, and you get real content to work with in designs and prototypes.

Once you’ve run a few things through your process, you’ll be able to refine your estimates, confirm your workflow, and give everyone involved a clear idea of when it will all be ready, and what you need from them.

Keeping it all on track

At this point I like to pull everything together into the content strategist’s favourite tool: the spreadsheet.

A simple content production checklist is a bit like a content inventory or audit, but for the content you don’t yet have, not the stuff already done. You can grab an example here.

Each piece of content gets its own row, with columns for basic information like page title, ID (which should match the site map), and who’s responsible for making it. You can capture simple details like target audience and key messages here too, though for more complex content, page description tables like those described by Relly Annett-Baker in “Extracting the Content” may be a better tool to use. Just adapt these columns to whatever makes sense for your content.

I then have columns to track where each piece is in the production process. I usually keep this simple, with a column each to mark whether it’s draft, final or uploaded. The status column on the left automatically shows the item’s status, using a simple traffic light colour scheme for whether the item is still to do (red), in draft (amber), or done (green). Seeing the whole thing slowly turn from red to green is a nice motivator.

If you want to track the workflow in more detail, a kanban board in a tool like Trello is a great way for a team to collaborate on content production, track each item’s progress, and keep an eye out for bottlenecks and delays. 

Getting to the content strategy conversation

It’s a relatively simple exercise, then, to decide not just what kinds of pages you need, but also how many of them: put some rough estimates of effort on the tasks needed to create those pages – not just the writing, but all the other stages of planning, reviewing, approving, publishing and promoting – and then multiply all those things together. This will quickly bring some reality to grand visions and overambitious plans. Do it early enough, and even when the final big scary number is a lot bigger and scarier than everyone thought, you’ll still have time to do something about it.

As well as getting everyone on board for some proper content planning activities, that big scary number is your opportunity to get to the real core questions of content strategy: do we really need all this content? Where can existing content be reused and repurposed? How do we prioritise our efforts? What really matters to our readers and users?

Time and again, case studies show that less content delivers more: more leads, more sales, more self-service support and savings in the call centre. Although that argument is primarily one you should make from a good-for-the-users perspective, it doesn’t hurt to be able to make it from the cheaper-for-the-business perspective as well, and to have some big scary numbers to back that up.",2014,Sophie Dennis,sophiedennis,2014-12-17T00:00:00+00:00,https://24ways.org/2014/content-production-planning/,content
34,Collaborative Responsive Design Workflows,"Much has been written about workflow and designer-developer collaboration in web design, but many teams still struggle with this issue; either with how to adapt their internal workflow, or how to communicate the need for best practices like mobile first and progressive enhancement to their teams and clients. Christmas seems like a good time to have another look at what doesn’t work between us and how we can improve matters.

Why is it so difficult?

We’re still beginning to understand responsive design workflows, acknowledging the need to move away from static design tools and towards best practices in development. It’s not that we don’t want to change – so why is it so difficult?

Changing the way we do something that has become routine is always problematic, even with small things, and the changes today’s web environment requires from web design and development teams are anything but small.

Although developers also have a host of new skills to learn and things to consider, designers are probably the ones pushed furthest out of their comfort zones: as well as graphic design, a web designer today also needs an understanding of interaction design and ergonomics, because more and more websites are becoming tools rather than pages meant to be read like a book or magazine. In addition to that there are thousands of different devices and screen sizes on the market today that layout and interactions need to work on.

These aspects make it impossible to design in a static design tool, so beyond having to learn about new aspects of design, the designer has to either learn how to code or learn to work with a responsive design tool.

Why do it

That alone is enough to leave anyone overwhelmed, as learning a new skill takes time and slows you down in a project – and on most projects time is in short supply. Yet we have to make time or fall behind in the industry as others pitch better, interactive designs. For an efficient workflow, both designers and developers must familiarise themselves with new tools and techniques.

A designer has to be able to play with ideas, make small adjustments here and there, look at the result, go back to the settings and make further adjustments, and so on. You can only realistically do that if you are able to play with all the elements of a design, including interactivity, accessibility and responsiveness.

Figuring out the right breakpoints in a layout is one of the foremost reasons for designing in a responsive design tool. Even if you create layouts for three viewport sizes (i.e. smartphone, tablet and the most common desktop size), you’d only cover around 30% of visitors and you might miss problems like line breaks and padding at other viewport sizes.

Another advantage is consistency. In static design tools changes will not be applied across all your other layouts. A developer referring back to last week’s comps might work with outdated metrics. Furthermore, you cannot easily test what impact changes might have on previously designed areas. In a dynamic design tool such changes will be applied to the entire design and allow you to test things in site areas you had already finished.

No static design tool allows you to do this, and having somebody else produce a mockup from your static designs or wireframes will duplicate work and is inefficient.

How to do it

When working in a responsive design tool rather than in the browser, there is still the question of how and when to communicate with the developer. I have found that working with Sass in combination with a visual style guide is very efficient, but it does need careful planning: fundamental metrics for padding, margins and font sizes, but also design elements like sliders, forms, tabs, buttons and navigational elements, should be defined at the beginning of a project and used consistently across the site. Working with a grid can help you develop a consistent design language across your site.

Create a visual style guide that shows what the elements look like and how they behave across different screen sizes – and when interacted with. Put all metrics on paddings, margins, breakpoints, widths, colours and so on in a text document, ideally with names that your developer can use as Sass variables in the CSS. For example:

$padding-default-vertical: 1.5em;

Developers, too, need an efficient workflow to keep code maintainable and speed up the time needed for more complex interactions with an eye on accessibility and performance. CSS preprocessors like Sass allow you to work with variables and mixins for default rules, as well as style sheet partials for different site areas or design elements. Create your own boilerplate to use for your projects and then update your variables with the information from your designer for each individual project.

How to get buy-in

One obstacle when implementing responsive design, accessibility and content strategy is the logistics of learning new skills and iterating on your workflow. Another is how to sell it. You might expect everyone on a project (including the client) to want to design and develop the best website possible: ultimately, a great site will lead to more conversions. However, we often hear that people find it difficult to convince their teammates, bosses or clients to implement best practices.

Why is that? Well, I believe a lot of it is down to how we sell it. You will have experienced this yourself: some people you trust to know what they are talking about, and others you don’t. Think about why you trust that first person but don’t buy what the other one is telling you. It is likely because person A has a self-assured, calm and assertive demeanour, while person B seems insecure and apologetic. To sell our ideas, we need to become person A! For a timid designer or developer suffering from imposter syndrome (like many of us do in this industry) that is a difficult task. So how can we become more confident in selling our expertise?

Write

We need to become experts. And I mean not just in writing great code or coming up with beautiful designs but at explaining why we’re doing what we’re doing. Why do you code this way or that? Why is this the best layout? Why does a website have to be accessible and responsive? Write about it. Putting your thoughts down on paper or screen is a really efficient way of getting your head around a topic and learning to make a case for something. You may even find that you come up with new ideas as you are writing, so you’ll become a better designer or developer along the way.

Talk

Then, talk about it. Start out in front of your team, then do a lightning talk at a web event near you, then a longer talk or workshop. Having to talk about a topic is going to help you put into spoken words the argument that you’ve previously put together in writing. Writing comes more easily when you’re starting out but we use a different register when writing than talking and you need to learn how to speak your case. Do the talk a couple of times and after each talk make adjustments where you found it didn’t work well. By this time, you are more than ready to make your case to the client. In fact, you’ve been ready since that first talk in front of your colleagues ;)

Pitch

Pitches used to be based on a presentation of static layouts for for three to five typical pages and three different designs. But if we want to sell interactivity, structure, usability, accessibility and responsiveness, we need to demonstrate these things and I believe that it can only do us good. I have seen a few pitches sitting in the client’s chair and static layouts are always sort of dull. What makes a website a website is the fact that I can interact with it and smooth interactions or animations add that extra sparkle.

I can’t claim personal experience for this one but I’d be bold and go for only one design. One demo page matching the client’s corporate design but not any specific page for the final site. Include design elements like navigation, photography, typefaces, article layout (with real content), sliders, tabs, accordions, buttons, forms, tables (yes, tables) – everything you would include in a style tiles document, only interactive. Demonstrate how the elements behave when clicked, hovered and touched, and how they change across different screen sizes. You may even want to demonstrate accessibility features like tabbed navigation and screen reader use.

Obviously, there are many approaches that will work in different situations but don’t give up on finding a process that works for you and that ultimately allows you to build delightful, accessible, responsive user experiences for the web. Make time to try new tools and techniques and don’t just work on them on the side – start using them on an actual project. It is only when we use a tool or process in the real world that we become true experts.

32,Cohesive UX,"With Yosemite, Apple users can answer iPhone calls on their MacBooks. This is weird. And yet it’s representative of a greater trend toward cohesion.

Shortly after upgrading to Yosemite, a call came in on my iPhone and my MacBook “rang” in parallel. And I was all, like, “Wut?” This was a new feature in Yosemite, and honestly it was a little bizarre at first.

 Apple promotional image showing a phone call ringing simultaneously on multiple devices.

However, I had just spoken at a conference on the very topic you’re reading about now, and therefore I appreciated the underlying concept: the cohesion of user experience, the cohesion of screens.

This is just one of many examples I’ve encountered since beginning to speak about this topic months ago. But before we get ahead of ourselves, let’s look back at the past few years, specifically the role of responsive web design.

RWD != cohesive experience

I needn’t expound on the virtues of responsive web design (RWD). You’ve likely already encountered more than a career’s worth on the topic. This is a good thing. Count me in as one of its biggest fans.

However, if we are to sing the praises of RWD, we must also acknowledge its shortcomings. One of these is that RWD ends where the browser ends. For all its goodness, RWD really has no bearing on native apps or any other experiences that take place outside the browser. This makes it challenging, therefore, to create cohesion for multi-screen users if RWD is the only response to “let’s make it work everywhere.”

We need something that incorporates the spirit of RWD while unifying all touchpoints for the entire user experience—single device or several devices, in browser or sans browser, native app or otherwise.

I call this cohesive UX, and I believe it’s the next era of successful user experiences.

Toward a unified whole

Simply put, the goal of cohesive UX is to deliver a consistent, unified user experience regardless of where the experience begins, continues, and ends.

Two facets are vital to cohesive UX:


	Function and form
	Data symmetry


Let’s examine each of these.

Function AND form

Function over form, of course. Right? Not so fast, kiddo.

Consider Bruce Lawson’s dad. After receiving an Android phone for Christmas and thumbing through his favorite sites, he was puzzled why some looked different from their counterparts on the desktop. “When a site looked radically different,” Bruce observed, “he’d check the URL bar to ensure that he’d typed in the right address. In short, he found RWD to be confusing and it meant he didn’t trust the site.” A lack of cohesive form led to a jarring experience for Bruce’s dad.

Now, if I appear to be suggesting websites must look the same in every browser—you already learned they needn’t—know that I recognize the importance of context, especially in regards to mobile. I made a case for this more than seven years ago.

Rather, cohesive UX suggests that form deserves the same respect as function when crafting user experiences that span multiple screens or devices. And users are increasingly comfortable traversing media. For example, more than 40% of adults in the U.S. owning more than one device start an activity on one screen and finish it on another, according to a study commissioned by Facebook. I suspect that percentage will only increase in 2015, and I suspect the tech-affluent readers of 24 ways are among the 40%.

There are countless examples of cohesive form and function. Consider Gmail, which displays email conversations visually as a stack that can be expanded and collapsed like the bellows of an accordion. This visual metaphor has been consistent in virtually any instance of Gmail—website or app—since at least 2007 when I captured this screenshot on my Nokia 6680:

 Screenshot captured while authoring Mobile Web Design (2007). Back then we didn’t call this an app, but rather a ‘smart client’.

When the holistic experience is cohesive as it is with Gmail, users’ mental models and even muscle memory are preserved.1 Functionality and aesthetics align with the expectations users have for how things should function and what they should look like. In other words, the experience is roughly the same across screens.

But don’t be ridiculous, peoples. Note that I said “roughly.” It’s important to avoid mindless replication of aesthetics and functionality for the sake of cohesion. Again, the goal is a unified whole, not a carbon copy. Affordances and concessions should be made as context and intuition require. For example, while Facebook users are accustomed to top-aligned navigation in the browser, they encounter bottom-aligned navigation in the iOS app as justified by user testing:

The iOS app model has held up despite many attempts to better it: http://t.co/rSMSAqeh9m pic.twitter.com/mBp36lAEgc— Luke Wroblewski (@lukew) December 10, 2014


Despite the (rather minor) lack of consistency in navigation placement, other elements such as icons, labels, and color theme work in tandem to produce a unified, holistic whole.

Data symmetry

Data symmetry involves the repetition, continuity, or synchronicity of data across screens, devices, and platforms. As regards cohesive UX, data includes not just the material (such as an article you’re writing on Medium) but also the actions that can be performed on or with that material (such as Medium’s authoring tools). That is to say, “sync verbs, not just nouns” (Josh Clark).

In my estimation, Amazon is an archetype of data symmetry, as is Rdio. When logged in, data is shared across virtually any device of any kind, irrespective of using a browser or native app. Add a product to your Amazon cart from your phone during the morning commute, and finish the transaction at work on your laptop. Easy peasy.

Amazon’s aesthetics are crazy cohesive, to boot:

 Amazon web (left) and native app (right).

With Rdio, not only are playlists and listening history synced across screens as you would expect, but the cohesion goes even further. Rdio’s remote control feature allows you to control music playing on one device using another device, all in real time.

 Rdio’s remote control feature, as viewed on my MacBook while music plays on my iMac.

At my office I often work from my couch using my MacBook, but my speakers are connected to my iMac. When signed in to Rdio on both devices, my MacBook serves as proxy for controlling Rdio on my iMac, much the same as any Yosemite-enabled device can serve as proxy for an incoming iPhone call.

 Me, in my office. Note the iMac and speakers at far right.

This is a brilliant example of cohesive design, and it’s executed entirely via the cloud.

Things to consider

Consider the following when crafting cohesive experiences:


	Inventory the elements that comprise your product experience, and cohesify them.2
Consider things such as copy, tone, typography, iconography, imagery, flow, placement, brand identification, account data, session data, user preferences, and so on. Then, create cohesion among these elements to the greatest extent possible, while adapting to context as needed.
	Store session data in the cloud rather than locally.
For example, avoid using browser cookies to store shopping cart data, as cookies are specific to a single browser on a single device. Instead, store this data in the cloud so it can be accessed from other devices, as well as beyond the browser.
	Consider using web views when developing your native app.
“You’re already using web apps in native wrappers without even noticing it,” Lukas Mathis contends. “The fact that nobody even notices, the fact that this isn’t a story, shows that, when it comes to user experience, web vs. native doesn’t matter anymore.” Web views essentially allow you to display HTML content inside a native wrapper. This can reduce the time and effort needed to make the overall experience cohesive. So whereas the navigation bar may be rendered by the app, for example, the remaining page display may be rendered via the web. There’s readily accessible documentation for using web views in C++, iOS, Android, and so forth.


Nature is calling

Returning to the example of Yosemite and sychronized phone calls, is it really that bizarre in light of cohesive UX? Perhaps at first. But I suspect that, over time, Yosemite’s cohesiveness — and the cohesiveness of other examples like the ones we’ve discussed here — will become not only more natural but more commonplace, too.



1 I browse Flipboard on my iPad nearly every morning as part of my breakfast routine. Swiping horizontally advances to the next page. Countless times I’ve done the same gesture in Flipboard for iPhone only to have it do nothing. This is because the gesture for advancing is vertical on phones. I’m so conditioned to the horizontal swipe that I often fail to make the switch to vertical swipe, and apparently others suffer from the same muscle memory, too.

42,An Overview of SVG Sprite Creation Techniques,"SVG can be used as an icon system to replace icon fonts. The reasons why SVG makes for a superior icon system are numerous, but we won’t be going over them in this article. If you don’t use SVG icons and are interested in knowing why you may want to use them, I recommend you check out “Inline SVG vs Icon Fonts” by Chris Coyier – it covers the most important aspects of both systems and compares them with each other to help you make a better decision about which system to choose.

Once you’ve made the decision to use SVG instead of icon fonts, you’ll need to think of the best way to optimise the delivery of your icons, and ways to make the creation and use of icons faster.

Just like bitmaps, we can create image sprites with SVG – they don’t look or work exactly alike, but the basic concept is pretty much the same.

There are several ways to create SVG sprites, and this article will give you an overview of three of them. While we’re at it, we’re going to take a look at some of the available tools used to automate sprite creation and fallback for us.

Prerequisites

The content of this article assumes you are familiar with SVG. If you’ve never worked with SVG before, you may want to look at some of the introductory tutorials covering SVG syntax, structure and embedding techniques. I recommend the following:


	SVG basics: Using SVG.
	Structure: Structuring, Grouping, and Referencing in SVG  —  The <g>, <use>, <defs> and <symbol> Elements. We’ll mention <use> and <symbol> quite a bit in this article.
	Embedding techniques: Styling and Animating SVGs with CSS. The article covers several topics, but the section linked focuses on embedding techniques.
	A compendium of SVG resources compiled by Chris Coyier  —  contains resources to almost every aspect of SVG you might be interested in.


And if you’re completely new to the concept of spriting, Chris Coyier’s CSS Sprites explains all about them.

Another important SVG feature is the viewBox attribute. For some of the techniques, knowing your way around this attribute is not required, but it’s definitely more useful if you understand – even if just vaguely – how it works. The last technique mentioned in the article requires that you do know the attribute’s syntax and how to use it. To learn all about viewBox, you can refer to my blog post about SVG coordinate systems.

With the prerequisites in place, let’s move on to spriting SVGs!

Before you sprite…

In order to create an SVG sprite with your icons, you’ll of course need to have these icons ready for use.

Some spriting tools require that you place your icons in a folder to which a certain spriting process is to be applied. As such, for all of the upcoming sections we’ll work on the assumption that our SVG icons are placed in a folder named SVG.

Each icon is an individual .svg file.

You’ll need to make sure each icon is well-prepared and optimised for use – make sure you’ve cleaned up the code by running it through one of the optimisation tools or processes available (or doing it manually if it’s not tedious).

After prepping the icon files and placing them in a folder, we’re ready to create our SVG sprite.

HTML inline SVG sprites

Since SVG is XML code, it can be embedded inline in an HTML document as a code island using the <svg> element. Chris Coyier wrote about this technique first on CSS-Tricks.

The embedded SVG will serve as a container for our icons and is going to be the actual sprite we’re going to use. So we’ll start by including the SVG in our document.

<!DOCTYPE html>
<!-- HTML document stuff -->

<svg style=""display:none;"">
  <!-- icons here -->
</svg>

<!-- other document stuff -->
</html>

Next, we’re going to place the icons inside the <svg>. Each icon will be wrapped in a <symbol> element we can then reference and use elsewhere in the page using the SVG <use> element. The <symbol> element has many benefits, and we’re using it because it allows us to define a symbol (which is a convenient markup for an icon) without rendering that symbol on the screen. The elements defined inside <symbol> will only be rendered when they are referenced – or called – by the <use> element.

Moreover, <symbol> can have its own viewBox attribute, which makes it possible to control the positioning of its content inside its container at any time.

Before we move on, I’d like to shed some light on the style=""display:none;"" part of the snippet above. Without setting the display of the SVG to none, and even though its contents are not rendered on the page, the SVG will still take up space in the page, resulting in a big empty area. In order to avoid that, we’re hiding the SVG entirely with CSS.

Now, suppose we have a Twitter icon in the icons folder. twitter.svg might look something like this:

<!-- twitter.svg -->
<?xml version=""1.0"" encoding=""utf-8""?>
<!DOCTYPE svg PUBLIC ""-//W3C//DTD SVG 1.1//EN"" ""http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd"">

</svg>

We don’t need the root svg element, so we’ll strip the code and only keep the parts that make up the Twitter icon’s shape, which in this example is just the <path> element.Let’s drop that into the sprite container like so:

<svg style=""display:none;"">
  <symbol id=""twitter-icon"" viewBox=""0 0 32 32"">
    <path d=""M32 6.076c-1.177 …"" fill=""#000000""></path>
  </symbol>

 <!-- remaining icons here -->
  <symbol id=""instagram-icon"" viewBox=""0 0 32 32"">
   <!-- icon contents -->
  </symbol>

  <!-- etc. -->
</svg>

Repeat for the other icons.

The value of the <symbol> element’s viewBox attribute depends on the size of the SVG. You don’t need to know how the viewBox works to use it in this case. Its value is made up of four parts: the first two will almost always be “0 0”; the second two will be equal to the size of the icon. For example, our Twitter icon is 32px by 32px (see twitter.svg above), so the viewBox value is “0 0 32 32”.

That said, it is certainly useful to understand how the viewBox works – it can help you troubleshoot SVG sometimes and gives you better control over it, allowing you to scale, position and even crop SVGs manually without having to resort to an editor. My blog post explains all about the viewBox attribute and its related attributes.

Once you have your SVG sprite ready, you can display the icons anywhere on the page by referencing them using the SVG <use> element:

<svg class=""twitter-icon"">
  <use xlink:href=""#twitter-icon""></use>
<svg>

And that’s all there is to it!

HTML-inline SVG sprites are simple to create and use, but when you have a lot of icons (and the more icon sets you create) it can easily become daunting if you have to manually transfer the icons into the <svg>. Fortunately, you don’t have to do that. Fabrice Weinberg created a Grunt plugin called grunt-svgstore which takes the icons in your SVG folder and generates the SVG sprites for you; all you have to do is just drop the sprites into your page and use the icons like we did earlier.

This technique works in all browsers supporting SVG. There seems to be a bug in Safari on iOS which causes the icons not to show up when the SVG sprite is defined at the bottom of the document after the <use> references to the icons, so it’s safest to include the sprite before you use the icons until this bug is fixed.

This technique has one disadvantage: the SVG sprite cannot be cached. We’re saving an extra HTTP request here but the browser cannot cache the image, so we aren’t speeding up any subsequent page loads by inlining the SVG. There must be a better way – and there is.

Styling the icons is possible, but getting deep into the styles becomes a bit harder owing to the nature of the contents of the <use> element – these contents are cloned into a shadow DOM, and hence selecting elements in CSS the traditional way is not possible. However, some techniques to work around that do exist, and give us slightly more styling flexibility. Animations work as expected.

Referencing an external SVG sprite in HTML

Instead of including the SVG inline in the document, you can reference the sprite and the icons inside it externally, taking advantage of fragment identifiers to select individual icons in the sprite.

For example, the above reference to the Twitter icon would look something like this instead:

<svg class=""twitter-icon"">
  <use xlink:href=""path/to/icons.svg#twitter-icon""></use>
<svg>


icons.svg is the name of the SVG file that contains all of our icons as symbols, and the fragment identifier #twitter-icon is the reference to the <symbol> wrapping the Twitter icon’s contents. Very convenient, isn’t it? The browser will request the sprite and then cache it, speeding up subsequent page loads. Win!

This technique also works in all browsers supporting SVG except Internet Explorer – not even IE9+ with SVG support permits this technique. No version of IE supports referencing an external SVG in <use>.

Fortunately (again), Jonathan Neil has created a plugin called svg4everybody which fills this gap in IE; you can reference an external sprite in <use> and also provide fallback for browsers that do not support SVG. However, it requires you to have the fallback images (PNG or JPEG, for example) available to do so. For details, refer to the plugin’s Github repository’s readme file.

CSS inline SVG sprites

Another way to create an SVG sprite is by inlining the SVG icons in a style sheet using data URIs, and providing fallback for non-supporting browsers – also within the CSS.

Using this approach, we’re turning the style sheet into the sprite that includes our icons. The style sheet is normally cached by the browser, so we have that concern out of the way.

This technique is put into practice in Filament Group’s icon system approach, which uses their Grunticon plugin – or its sister Grumpicon web app – for generating the necessary CSS for the sprite. As such, we’re going to cover this technique by following a workflow that uses one of these tools.

Again, we start with our icon SVG files. To focus on the actual spriting method and not on the tooling, I’ll go over the process of sprite creation using the Grumpicon web app, instead of the Grunticon plugin. Both tools generate the same resources that we’re going to use for the icon system. Whether you choose the web app or the Grunt set-up, after processing your SVG folder you’re going to end up with the same set of resources that we’ll be using throughout this section.

The first step is to drop your icons into the Grumpicon web app.

 Grumpicon homepage screenshot.

The application will then show you a preview of your icons, and a download button will allow you to download the generated files. These files will contain everything you need for your icon system – all that’s left is for you to drop the generated files and code into your project as recommended and you’ll have your sprite and icons ready to use anywhere you want in your page.

Grumpicon generates five files and one folder in the downloaded package: a png folder containing PNG versions of your icons; three style sheets (that we’ll go over briefly); a loader script file; and preview.html which is a live example showing you the other files in action.

The script in the loader goes into the <head> of your page. This script handles browser and feature detection, and requests the necessary style sheet depending on browser support for SVG and base64 data URIs. If you view the source code of the preview page, you can see exactly how the script is added.

icons.data.svg.css is the style sheet that contains your icons – the sprite. The icons are embedded inline inside the style sheet using data URIs, and applied to elements of your choice as background images, using class names. For example:

.twitter-icon{
    background-image: url('data:image/svg+xml;…'); /* the ellipsis is where the icon’s data would go */
    background-repeat: no-repeat;
    background-position: 50% 50%;
    height: 2em;
    width: 2em;
    /* etc. */
}

Then, you only have to apply the twitter-icon class name to an element in your HTML to apply the icon as a background to it:

<span class=""twitter-icon""></span>

And that’s all you need to do to get an icon on the page.

icons.data.svg.css, along with the other two style sheets and the png folder should be added to your CSS folder.

icons.data.png.css is the style sheet the script will load in browsers that don’t support SVG, such as IE8. Fallback for the inline SVG is provided as a base64-encoded PNG. For instance, the fallback for the Twitter icon from our example would look like so:

.twitter-icon{
    background-image: url('data:image/png;base64;…’);
    /* etc. */
}

icons.fallback.css is the style sheet required for browsers that don’t support base64-encoded PNGs – the PNG images are loaded as usual using the image’s URL. The script will load this style sheet for IE6 and IE7, for example.

.twitter-icon{
    background-image: url(png/twitter-icon.png);
    /* etc. */
}

This technique is very different from the previous one. The sprite in this case is literally the style sheet, not an SVG container, and the icon usage is very similar to that of a CSS sprite – the icons are provided as background images.

This technique has advantages and disadvantages. For the sake of brevity, I won’t go into further details, but the main limitations worth mentioning are that SVGs embedded as background images cannot be styled with CSS; and animations are restricted to those defined inside the <svg> for each icon. CSS interactions (such as hover effects) don’t work either. Thus, to apply an effect for an icon that changes its color on hover, for example, you’ll need to export a set of SVGs for each colour in order for Grumpicon to create matching fallback PNG images that can then be used for the animation.

For more details about the Grumpicon workflow, I recommend you check out “A Designer’s Guide to Grumpicon” on Filament Group’s website.

Using SVG fragment identifiers and views

This spriting technique is, again, different from the previous ones, and it is my personal favourite.

SVG comes with a standard way of cropping to a specific area in a particular SVG image. If you’ve ever worked with CSS sprites before then this definitely sounds familiar: it’s almost exactly what we do with CSS sprites – the image containing all of the icons is cropped, so to speak, to show only the one icon that we want in the background positioning area of the element, using background size and positioning properties.

Instead of using background properties, we’ll be using SVG’s viewBox attribute to crop our SVG to the specific icon we want.

What I like about this technique is that it is more visual than the previous ones. Using this technique, the SVG sprite is treated like an actual image containing other images (the icons), instead of treating it as a piece of code containing other code.

Again, our SVG icons are placed inside a main SVG container that is going to be our SVG sprite. If you’re working in a graphics editor, position or arrange your icons inside the canvas any way you want them to be, and then export the graphic as is. Of course, the less empty space there is in your SVG, the better.

In our example, the sprite contains three icons as shown in the following image. The sprite is open in Sketch. Notice how the SVG is just big enough to fit the icons inside it. It doesn’t have to be like this, but it’s cleaner this way.

 Screenshot showing the SVG sprite containing our icons.

Now, suppose you want to display only the Instagram icon. Using the SVG viewBox attribute, we can crop the SVG to the icon. The Instagram icon is positioned at 64px along the positive x-axis, and zero pixels along the y-axis. It is also 32px by 32px in size.

 Screenshot showing the position (offset) of the Instagram icon inside the SVG sprite, and its size.

Using this information, we can specify the value of the viewBox as: 64 0 32 32. This area of the view box contains only the Instagram icon. 64 0 specifies the top-left corner of the view box area, and 32 32 specify its dimensions.

Now, if we were to change the viewBox value on the SVG sprite to this value, only the Instagram icon will be visible inside the SVG viewport. Great. But how do we use this information to display the icon in our page using our sprite?

SVG comes with a native way to link to portions or areas of an image using fragment identifiers. Fragment identifiers are used to link into a particular view area of an SVG document. Thus, using a fragment identifier and the boundaries of the area that we want (from the viewBox), we can link to that area and display it.

For example, if you want to display the icon from the sprite using an <img> tag, you can reference the icon in the sprite like so:

<img src='uiIcons.svg#svgView(viewBox(64, 0, 32, 32))' alt=""Settings icon""/>

The fragment identifier in the snippet above (#svgView(viewBox(64, 0, 32, 32))) is the important part. This will result in only the Instagram icon’s area of the sprite being displayed.

There is also another way to do this, using the SVG <view> element. The <view> element can be used to define a view area and then reference that area somewhere else. For example, to define the view box containing the Instagram icon, we can do the following:

<view id='instagram-icon' viewBox='64 0 32 32' />

Then, we can reference this view in our <img> element like this:

<img src='sprite.svg#instagram-icon' alt=""Instagram icon"" />

The best part about this technique – besides the ability to reference an external SVG and hence make use of browser caching – is that it allows us to use practically any SVG embedding technique and does not restrict us to specific tags.

It goes without saying that this feature can be used for more than just icon systems, owing to viewBox’s power in controlling an SVG’s viewable area.

SVG fragment identifiers have decent browser support, but the technique is buggy in Safari: there is a bug that causes problems when loading a server SVG file and then using fragment identifiers with it. Bear Travis has documented the issue and a workaround.

Where to go from here

Pick the technique that works best for your project. Each technique has its own pros and cons, relating to convenience and maintainability, performance, and styling and scripting. Each technique also requires its own fallback mechanism.

The spriting techniques mentioned here are not the only techniques available. Other methods exist, such as SVG stacks, and others may surface in future, but these are the three main ones today.

The third technique using SVG’s built-in viewBox features is my favourite, and with better browser support and fewer (ideally, no) bugs, I believe it is more likely to become the standard way to create and use SVG sprites. Fallback techniques can be created, of course, in one of many possible ways.

Do you use SVG for your icon system? If so, which is your favourite technique? Do you know or have worked with other ways for creating SVG sprites?",2014,Sara Soueidan,sarasoueidan,2014-12-16T00:00:00+00:00,https://24ways.org/2014/an-overview-of-svg-sprite-creation-techniques/,code
48,A Holiday Wish,"A friend and I were talking the other day about why clients spend more on toilet cleaning than design, and how the industry has changed since the mid-1990s, when we got our starts. Early in his career, my friend wrote a fine CSS book, but for years he has called himself a UX designer. And our conversation got me thinking about how I reacted to that title back when I first started hearing it.

“Just what this business needs,” I said to myself, “another phony expert.”

Okay, so I was wrong about UX, but my touchiness was not altogether unfounded. In the beginning, our industry was divided between freelance jack-of-all-trade punks, who designed and built and coded and hosted and Photoshopped and even wrote the copy when the client couldn’t come up with any, and snot-slick dot-com mega-agencies that blew up like Alice and handed out titles like impoverished nobles in the years between the world wars. 

I was the former kind of designer, a guy who, having failed or just coasted along at a cluster of other careers, had suddenly, out of nowhere, blossomed into a web designer—an immensely curious designer slash coder slash writer with a near-insatiable lust to shave just one more byte from every image. We had modems back then, and I dreamed in sixteen colors. My source code was as pretty as my layouts (arguably prettier) and I hoovered up facts and opinions from newsgroups and bulletin boards as fast as any loudmouth geek could throw them. It was a beautiful life.

But soon, too soon, the professional digital agencies arose, buying loft buildings downtown, jacking in at T1 speeds, charging a hundred times what I did, and communicating with their clients in person, in large artfully bedecked rooms, wearing hand-tailored Barney’s suits and bringing back the big city bullshit I thought I’d left behind when I quit advertising to become a web designer. 

Just like the big bad ad agencies of my early career, the new digital agencies stocked every meeting with a totem pole worth of ranks and titles. If the client brought five upper middle managers to the meeting, the agency did likewise. If fifteen stakeholders got to ask for a bigger logo, fifteen agency personnel showed up to take notes on the percentage of enlargement required.

But my biggest gripe was with the titles.

The bigger and more expensive the agency, the lousier it ran with newly invented titles. Nobody was a designer any more. Oh, no. Designer, apparently, wasn’t good enough. Designer was not what you called someone you threw that much money at.

Instead of designers, there were user interaction leads and consulting middleware integrators and bilabial experience park rangers and you name it. At an AIGA Miami event where I was asked to speak in the 1990s, I once watched the executive creative director of the biggest dot-com agency of the day make a presentation where he spent half his time bragging that the agency had recently shaved down the number of titles for people who basically did design stuff from forty-six to just twenty-three—he presented this as though it were an Einsteinian coup—and the other half of his time showing a film about the agency’s newly opened branch in Oslo. The Oslo footage was shot in December. I kept wondering which designer in the audience who lived in the constant breezy balminess of Miami they hoped to entice to move to dark, wintry Norway. But I digress.

Shortly after I viewed this presentation, the dot-com world imploded, brought about largely by the euphoric excess of the agencies and their clients. But people still needed websites, and my practice flourished—to the point where, in 1999, I made the terrifying transition from guy in his underwear working freelance out of his apartment to head of a fledgling design studio. (Note: you never stop working on that change.)

I had heard about experience design in the 1990s, but assumed it was a gig for people who only knew one font. 

But sometime around 2004 or 2005, among my freelance and small-studio colleagues, like a hobbit in the Shire, I began hearing whispers in the trees of a new evil stirring. The fires of Mordor were burning. Web designers were turning in their HTML editing tools and calling themselves UXers.

I wasn’t sure if they pronounced it “uck-sir,” or “you-ex-er,” but I trusted their claims to authenticity about as far as I trusted the actors in a Doctor Pepper commercial when they claimed to be Peppers. I’m an UXer, you’re an UXer, wouldn’t you like to be an UXer too? No thanks, said I. I still make things. With my hands.

Such was my thinking. I may have earned an MFA at the end of some long-past period of soul confusion, but I have working-class roots and am profoundly suspicious of, well, everything, but especially of anything that smacks of pretense. I got exporting GIFs. I didn’t get how white papers and bullet points helped anybody do anything.

I was wrong. And gradually I came to know I was wrong. And before other members of my tribe embraced UX, and research, and content strategy, and the other airier consultant services, I was on board. It helped that my wife of the time was a librarian from Michigan, so I’d already bought into the cult of information architecture. And if I wasn’t exactly the seer who first understood how borderline academic practices related to UX could become as important to our medium and industry as our craft skills, at least I was down a lot faster than Judd Apatow got with feminism. But I digress.

I love the web and all the people in it. Today I understand design as a strategic practice above all. The promise of the web, to make all knowledge accessible to all people, won’t be won by HTML5, WCAG 2, and responsive web design alone. 

We are all designers. You may call yourself a front-end developer, but if you spend hours shaving half-seconds off an interaction, that’s user experience and you, my friend, are a designer. If the client asks, “Can you migrate all my old content to the new CMS?” and you answer, “Of course we can, but should we?”, you are a designer. Even our users are designers. Think about it. 

Once again, as in the dim dumb dot-com past, we seem to be divided by our titles. But, O, my friends, our varied titles are only differing facets of the same bright gem. Sisters, brothers, we are all designers. Love on! Love on!

And may all your web pages, cards, clusters, clumps, asides, articles, and relational databases be bright.",2014,Jeffrey Zeldman,jeffreyzeldman,2014-12-18T00:00:00+00:00,https://24ways.org/2014/a-holiday-wish/,ux
1,Why Bother with Accessibility?,"Web accessibility (known in other fields as inclusive design or universal design) is the degree to which a website is available to as many people as possible. Accessibility is most often used to describe how people with disabilities can access the web.

How we approach accessibility

In the web community, there’s a surprisingly inconsistent approach to accessibility. There are some who are endlessly dedicated to accessible web design, and there are some who believe it so intrinsic to the web that it shouldn’t be considered a separate topic. Still, of those who are familiar with accessibility, there’s an overwhelming number of designers, developers, clients and bosses who just aren’t that bothered.

Over the last few months I’ve spoken to a lot of people about accessibility, and I’ve heard the same reasons to ignore it over and over again. Let’s take a look at the most common excuses.

Excuse 1: “People with disabilities don’t really use the web”

Accessibility will make your site available to more people — the inclusion case

In the same way that the accessibility of a building isn’t just about access for wheelchair users, web accessibility isn’t just about blind users and screen readers. We can affect positively the lives of many people by making their access to the web easier.

There are four main types of disability that affect use of the web:


	Visual
	Blindness, low vision and colour-blindness
	Auditory
	Profoundly deaf and hard of hearing
	Motor
	The inability to use a mouse, slow response time, limited fine motor control
	Cognitive
	Learning difficulties, distractibility, the inability to focus on large amounts of information


None of these disabilities are completely black and white

Examining deafness, it’s clear from the medical scale that there are many grey areas between full hearing and total deafness:


	mild
	moderate
	moderately severe
	severe
	profound
	totally deaf


For eyesight, and brain conditions that affect what users see, there is a huge range of conditions and challenges:


	astigmatism
	colour blindness
	akinetopsia (motion blindness)
	scotopic visual sensitivity (visual stress related to light)
	visual agnosia (impaired recognition or identification of objects)


While we might have medical and government-recognised definitions that tell us what makes a disability, day-to-day life is not so straightforward. People experience varying degrees of different conditions, and often one or more conditions at a time, creating a false divide when you view disability in terms of us and them.

Impairments aren’t always permanent

As we age, we’re more likely to experience different levels of visual, auditory, motor and cognitive impairments. We might have an accident or illness that affects us temporarily. We might struggle more earlier or later in the day. There are so many little physiological factors that affect the way people interact with the web that we can’t afford to make any assumptions based on our own limited experiences.

Impairments might be somewhere between the user and the website

There are also impairments that aren’t directly related to the user. Environmental factors have a huge effect on the way people interact with the web. These could be:


	Low bandwidth, or intermittent internet connection
	Bright light, rain, or other weather-based conditions
	Noisy environments, or a location where the user doesn’t want to disturb their neighbours with sound
	Browsing with mobile devices, games consoles and other non-desktop devices
	Browsing with legacy browsers or operating systems


Such environmental factors show that it’s not just those with physical impairments who benefit from more accessible websites. We started designing responsive websites so we could be more future-friendly, and with a shared goal of better optimised experiences, accessibility should be at the core of responsive web design.

Excuse 2: “We don’t want to affect the experience for the majority of our users”

Accessibility will improve your site for all your users — the usability case

On a basic level, the different disability groups, as shown in the inclusion case, equate to simple usability goals:


	Visual – make it easy to read
	Auditory – make it easy to hear
	Motor – make it easy to interact
	Cognitive – make it easy to understand and focus


Taking care to ensure good usability in these areas will also have an impact on accessibility. Unless your site is catering specifically to a particular disability, where extreme optimisation is most beneficial, taking care to design with accessibility in mind will rarely negatively affect the experience of your wider audience.

Excuse 3: “We don’t have the budget for accessibility”

Accessibility will make you money — the business case

By reducing your audience through ignoring accessibility, you’re potentially excluding the income from those users. Designing with accessibility in mind from the beginning of a project makes it easier to make small inexpensive optimisations as part of the design and development process, rather than bolting on costly updates to increase your potential audience later on.

The following are excerpts from a white paper about companies that increased the accessibility of their websites to comply with government regulation.


	Improvements in accessibility doubled Legal and General’s life insurance sales online.



	Improvements in accessibility increased Tesco’s grocery home delivery sales by £13 million in 2005… To their surprise they found that many normal visitors preferred the ease of navigation and improved simplicity of the [parallel] accessible site and switched to use it. Tesco have replaced their ‘normal’ site with their accessible version and expect a further increase in revenues.



	Improvements in accessibility increased Virgin.net sales by 68%.

Excuse 4: “Accessible websites are ugly”

Accessibility won’t stop your site from being beautiful — the beauty case

Many people use ugly accessible websites as proof that all accessible websites are ugly. This just isn’t the case. I’ve compiled some examples of beautiful and accessible websites with screenshots of how they look through the Color Oracle simulator and how they perform when run through Webaim’s Wave accessibility checker tool.

While automated tools are no substitute for real users, they can help you learn more about good practices, and give you guidance on where your site needs improvements to make it more accessible.

Amazon.co.uk

It may not be a decorated beauty, but Amazon is often first in functional design. It’s a huge website with a lot of interactive content, but it generates just five errors on the Wave test, and is easy to read under a Color Oracle filter.

24 ways

When Tim Van Damme redesigned 24 ways back in 2007, it was a striking and unusual design that showed what could be achieved with CSS and some imagination. Despite the complexity of the design, it gets an outstanding zero errors on the Wave test, and is still readable under a Color Oracle filter.

Opera’s Shiny Demos

Demos and prototypes are notorious for ignoring accessibility, but Opera’s Shiny Demos site shows how exploring new technologies doesn’t have to exclude anyone. It only gets one error on the Wave test, and looks fine under a Color Oracle filter.

SoundCloud

When a site is more app-like, relying on more interaction from the user, accessibility can be more challenging. However, SoundCloud only gets one error on the Wave test, and the colour contrast holds up well under a Color Oracle filter.

Education and balance

As with most web design, doing accessibility well is about combining your knowledge of accessibility with your project’s context to create a balance that serves your users’ needs. Your types of content and interactions will dictate one set of constraints. Your users’ needs and goals will dictate another. In broad terms, web design as a practice is finding the equilibrium between these constraints.

And then there’s just caring. The web as a platform is open, affordable and available to many. Accessibility is our way to ensure that nobody gets shut out.",2013,Laura Kalbag,laurakalbag,2013-12-10T00:00:00+00:00,https://24ways.org/2013/why-bother-with-accessibility/,design
24,Kill It With Fire! What To Do With Those Dreaded FAQs,"In the mid-1640s, a man named Matthew Hopkins attempted to rid England of the devil’s influence, primarily by demanding payment for the service of tying women to chairs and tossing them into lakes.

Unsurprisingly, his methods garnered criticism. Hopkins defended himself in The Discovery of Witches in 1647, subtitled “Certaine Queries answered, which have been and are likely to be objected against MATTHEW HOPKINS, in his way of finding out Witches.”

Each “querie” was written in the voice of an imagined detractor, and answered in the voice of an imagined defender (always referring to himself as “the discoverer,” or “him”):


	Quer. 14.

	All that the witch-finder doth is to fleece the country of their money, and therefore rides and goes to townes to have imployment, and promiseth them faire promises, and it may be doth nothing for it, and possesseth many men that they have so many wizzards and so many witches in their towne, and so hartens them on to entertaine him.

	Ans.

	You doe him a great deale of wrong in every of these particulars.


Hopkins’ self-defense was an early modern English FAQ.

Digital beginnings

Question and answer formatting certainly isn’t new, and stretches back much further than witch-hunt days. But its most modern, most notorious, most reviled incarnation is the internet’s frequently asked questions page.

FAQs began showing up on pre-internet mailing lists as a way for list members to answer and pre-empt newcomers’ repetitive questions:


	The presumption was that new users would download archived past messages through ftp. In practice, this rarely happened and the users tended to post questions to the mailing list instead of searching its archives. Repeating the “right” answers becomes tedious…


When all the users of a system can hear all the other users, FAQs make a lot of sense: the conversation needs to be managed and manageable. FAQs were a stopgap for the technological limitations of the time.

But the internet moved past mailing lists. Online information can be stored, searched, filtered, and muted; we choose and control our conversations. New users no longer rely on the established community to answer their questions for them.

And yet, FAQs are still around. They’re a content anti-pattern, replicated from site to site to solve a problem we no longer have.

What we hate when we hate FAQs

As someone who creates and structures online content – always with the goal of making that content as useful as possible to people – FAQs drive me absolutely batty. Almost universally, FAQs represent the opposite of useful. A brief list of their sins:


Double trouble
Duplicated content is practically a given with FAQs. They’re written as though they’ll be accessed in a vacuum – but search results, navigation patterns, and curiosity ensure that users will seek answers throughout the site. Is our goal to split their focus? To make them uncertain of where to look? To divert them to an isolated microcosm of the website? Duplicated content means user confusion (to say nothing of the duplicated workload for maintaining content).
Leaving the job unfinished
Many FAQs fail before they’re even out of the gate, presenting a list of questions that’s incomplete (too short and careless to be helpful) or irrelevant (avoiding users’ real concerns in favor of soundbites). Alternately, if the right questions are there, the answers may be convoluted, jargon-heavy, or otherwise difficult to understand.
Long lists of not-my-question
Getting a single answer often means sifting through a haystack of questions. For each potential question, the user must read, comprehend, assess, move on, rinse, repeat. That’s a lot of legwork for little reward – and a lot of opportunity for mistakes. Users may miss their question, or they may fail to recognize a differently worded version of their question, or they may not notice when their sought-after answer appears somewhere they didn’t expect.
The ventriloquist act
FAQs shift the point of view. While websites speak on behalf of the organization (“our products,” “our services,” “you can call us for assistance,” etc.), FAQs speak as the user – “I can’t find my password” or “How do I sign up?” Both voices are written from the first-person perspective, but speak for different entities, which is disorienting: it breaks the tone and messaging across the website. It’s also presumptuous: why do you get to speak for the user?


These all underscore FAQs’ fatal flaw: they are content without context, delivered without regard for the larger experience of the website. You can hear the absurdity in the name itself: if users are asking the same questions so frequently, then there is an obvious gulf between their needs and the site content. (And if not, then we have a labeling problem.)

Instead of sending users to a jumble of maybe-it’s-here-maybe-it’s-not questions, the answers to FAQs should be found naturally throughout a website. They are not separated, not isolated, not other. They are the content.

To present it otherwise is to create a runaround, and users know it. Jay Martel’s parody, “F.A.Q.s about F.A.Q.s” captures the silliness and frustration of such a system:


	Q: Why are you so rude?

	A: For that answer, you would have to consult an F.A.Q.s about F.A.Q.s about F.A.Q.s. But your time might be better served by simply abandoning your search for a magic answer and taking responsibility for your own profound ignorance.


FAQs aren’t magic answers. They don’t resolve a content dilemma or even help users. Yet they keep cropping up, defiant, weedy, impossible to eradicate.

Where are they all coming from?

Blame it on this: writing is hard. When generating content, most of us do whatever it takes to get some words on the screen. And the format of question and answer makes it easy: a reactionary first stab at content development.

After all, the point of website content is to answer users’ questions. So this – to give everyone credit – is a really good move. Content creators who think in terms of questions and answers are actually thinking of their users, particularly first-time users, trying to anticipate their needs and write towards them.

It’s a good start. But it’s scaffolding: writing that helps you get to the writing you’re supposed to be doing. It supports you while you write your way to the heart of your content. And once you get there, you have to look back and take the scaffolding down.

Leaving content in the Q&A format that helped you develop it is missing the point. You’re not there to build scaffolding. You have to see your content in its naked purpose and determine the best method for communicating that purpose – and it usually won’t be what got you there.

The goal (to borrow a lesson from content management systems) is to separate the content from its presentation, to let the meaning of the content inform its display.

This is, of course, a nice theory.

An occasionally necessary evil

I have a lot of clients who adore FAQs. They’ve developed their content over a long period of time. They’ve listened to the questions their users are asking. And they’ve answered them all on a page that I simply cannot get them to part with.

Which means I’ve had to consider that there may be occasions where an FAQ page is appropriate.

As an example: one of my clients is a financial office in a large institution. Because this office manages several third-party systems that serve a range of niche audiences, they had developed FAQs that addressed hyper-specific instances of dysfunction within systems for different users – à la “I’m a financial director and my employee submitted an expense report in such-and-such system and it returned such-and-such error. What do I do?”

Yes, this content could be removed from the question format and rewritten. But I’m not sure it would be an improvement. It won’t necessarily resolve concerns about length and searchability, and the different audiences may complicate the delivery. And since the work of rewriting it didn’t fit into the client workflow (small team, no writers, pressed for time), I didn’t recommend the change.

I’ve had to make peace with not being to torch all the FAQs on the internet. Some content, like troubleshooting information or complex procedures, may be better in that format. It may be the smartest way for a particular client to handle that particular information.

Of course, this has to be determined on a case-by-case basis, taking into account the amount of content, the subject matter, the skill levels of the content creators, the publishing workflow, and the search habits of the users.

If you determine that an FAQ page is the only way to go, ask yourself:


	Is there a better label or more specific term for the page (support, troubleshooting, product concerns, etc.)?
	Is there way to structure the page, categorize the questions, or otherwise make it easier for users to navigate quickly to the answer they need?
	Is a question and answer format absolutely the best way to communicate this information?


Form follows function

Just as a question and answer format isn’t necessarily required to deliver the content, neither is it an inappropriate method in and of itself. Content professionals have developed a knee-jerk reaction: It’s an FAQ page! Quick, burn it! Buuuuurn it!

But there’s no inherent evil in questions and answers. Framing content in an interrogatory construct is no more a deal with the devil than subheads and paragraphs, or narrative arcs, or bullet points.

Yes, FAQs are riddled with communication snafus. They deserve, more often than not, to be tied to a chair and thrown into a lake. But that wouldn’t fix our content problems. FAQs are a shiny and obvious target for our frustration, but they’re not unique in their flaws. In any format, in any display, in any kind of page, weak content can rear its ugly, poorly written head.

It’s not the Q&A that’s to blame, it’s bad content. Content without context will always fail users. That’s the real witch in our midst.",2013,Lisa Maria Martin,lisamariamartin,2013-12-08T00:00:00+00:00,https://24ways.org/2013/what-to-do-with-faqs/,content
19,In Their Own Write: Web Books and their Authors,"The currency of written communication — words on the page, words on the screen — comprises many denominations. To further our ends in web design and development, we freely spend and receive several: tweets aphoristic and trenchant, banal and perfunctory; blog posts and articles that call us to action or reflection; anecdotes, asides, comments, essays, guides, how-tos, manuals, musings, notes, opinions, stories, thoughts, tips pro and not-so-pro. So many, many words.

Our industry (so much more than this, but what on earth are we, collectively?), our community thrives on writing and sharing knowledge and experience. 24 ways is a case in point. Everyone can learn and contribute through reading and writing — it’s what we’ve always done.

To web authors and readers seeking greater returns, though, broader culture has vouchsafed an enduring and singular artefact: the book.

Last month I asked a small sample of web book authors if they would be prepared to answer a few questions; most of them kindly agreed. In spirit, the survey was informal: I had neither hypothesis nor unground axe. I work closely with writers — and yes, I’ve edited or copy-edited books by several of the authors I surveyed — and wanted to share their thoughts about what it was like to write a book (“…it was challenging to find a coherent narrative”), why they did it (“Who wouldn’t want to?”) and what they learned from the experience (“That I could!”).

Reasons for writing a book

In web development the connection between authors and readers is unusually close and immediate. Working in our medium precipitates a unity that’s rare elsewhere. Yet writing and publishing a book, even during the current books revolution, is something only a few of us attempt and it remains daunting and a little remote. What spurs an author to try it? For some, it’s a deeply held resistance to prevailing trends:

I felt that designers and developers needed to be shaken out of what seemed to me had been years of stagnation.
—Andrew Clarke


Or even a desire to protect us from ourselves:

I felt that without a book that clearly defined progressive enhancement in a very approachable and succinct fashion, the web was at risk. I was seeing Tim Berners-Lee’s vision of universal availability slip away…
—Aaron Gustafson


Sometimes, there’s a knowledge gap to be filled by an author with the requisite excitement and need to communicate. Jon Hicks took his “pet subject” and was “enthused enough to want to spend all that time writing”, particularly because:


	…there was a gap in the market for it. No one had done it before, and it’s still on its own out there, with no competition. It felt like I was able to contribute something.


Cennydd Bowles felt a professional itch at a particular point in his career, understanding that


	[a]s a designer becomes more senior, they start looking for ways to scale the effects of their work. For some, that leads into management. For others, into writing.


Often, though, it’s also simply a personal challenge and ambition to explore a subject at length and create something substantial. Anna Debenham describes a motivation shared by several authors:

To be able to point to something more tangible than an article and be able to say “I did that.”


That sense of a book’s significance, its heft and gravity even, stems partly from the cultural esteem which honours books and their authors. Books have a long history as sources of wisdom, truth and power. Even with more books being published each year than ever before, writing one is still commonly considered a laudable achievement, including in our field.

Challenges of writing a book

Received wisdom has it that writing online should be brief and chunky and approachable: get to the point; divide it all up; subheadings and lists are our friends; write like you’re talking; no one has time to read. Much of such advice is true. Followed well, it lends our writing punch and pith, vigour and vim. The web is nimble, the web keeps up, and it suits what we write about developing for it. It’s perfect for delivering our observations, queries and investigations into all the various aspects of the work, professional and personal.

Yet even for digital natives like web authors, books printed and electronic retain an attractive glister. 

Ideas can be developed more fully, their consequences explored to greater depth and extended with more varied examples, and the whole conveyed with more eloquence, more style. Why shouldn’t authors delay their conclusions if the intervening text is apposite, rich with value and helps to flesh out the skeleton of an argument? Conclusions might or might not be reached, of course, but a writer is at greater liberty in a book to digress in tangential and interesting ways.

Writing a book involves committing time, energy, thought and money. As Brian Suda found, it can be tough “getting the ideas out of my head into a cohesive blob of text.” Some authors end up talking to themselves…

It helps me to keep a real person in mind, someone who I’m talking to as I write. Sometimes I have the same conversations over and over in my head.
—Andrew Clarke


…while others are thinking ahead, concerned with how their book will be received:

Would anyone want to read it? Would they care? Would it be respected by my peers?
—Joe Leech


Challenges that arose time and again included “starting” and “getting words on the page” as well as “knowing when to stop” or “letting go”. Personal organization problems and those caused by publishers were also widely mentioned. Time loomed large. Making time, finding time. Giving up “sleep and some sanity” and realizing “it will take you far, far, far longer than you naively assumed”. Importantly, writing time is time away from gainful employment: Aaron Gustafson found the hardest thing about writing a book to be “the loss of income while I was writing.”

Perils and pleasures of editing

Editing, be it structural, technical or copy editing, is founded on reciprocity. Without openness and a shared belief that the book is worthwhile, work can founder in acrimony and mistrust. Editors are a book’s first and most critical (in every sense) readers. Effective and perceptive editing makes a book as good as it can be, finding the book within the draft like sculpture reveals the statue in the stone.

A good editor calls you out on poor assumptions and challenges you to really clarify your thinking. Whilst it can be difficult during the process to have your thinking challenged, it’s always been worth it — for me personally — in the long run. A good editor also reins you in when you’ve perhaps wandered off track or taken a little too long to make a point.
—Christopher Murphy


Andy Croll found editing “all positive” and Aaron Gustafson loves “working with a strong editor […] I want someone to tell it to me straight.” But it can be a rollercoaster, “both terrifying and the real moment of elation”. Mixed emotions during the editing process are common:

It was very uncomfortable! I knew it was making the work stronger, but it was awkward having my inconsistencies and waffle picked apart.
—Jon Hicks


It can be distressing to have written work looked over by a professional, particularly for first-time book authors whose expertise lies elsewhere:

I was a little nervous because I don’t consider myself a skilled writer — I never dreamed of becoming an author. I’m a designer, after all.
—Geri Coady


Communication is key, particularly when it comes to checking or changing the author’s words.

I like a good banter between me and the tech editor — if we can have a proper argument in Word comments, that’s great.
—Rachel Andrew


But if handled poorly, small battles can break out. Rachel Andrew again:


	However, having had plenty of times where the technical editor has done nothing more than give a cursory glance, I started to leave little issues in for them to spot. If they picked them up I knew they were actually testing the code and I could be sure the work was being properly tech edited. If they didn’t spot them, I’d find someone myself to read through and check it!


A major concern for writers is that their voices will be altered, filtered, mangled or otherwise obscured by the editing process. Good copy editing must remain unnoticed while enhancing the author’s voice in print. Donna Spencer appreciated the way her editor “tidied up my work and made it a million times better, but left it sounding exactly like me.” Similarly, Andrew Travers “was incredibly impressed at how well my editor tightened up my own writing without it feeling like another’s voice” and Val Head sums up the consensus that:


	the editor was able to help me express what I was trying to say in a better way […] I want to have editors for everything now.


At the keyboard, keep your friends close, but your editors closer.

Publishing and publishers

Conditions ought to militate against the allure of writing a book about web design and development. More books are published each year than ever before, so readerships elude new authors and readers can struggle to find authors to trust in their fields of interest. New spaces for more expansive online writing about working on and with the web are opening up (sites like Contents Magazine and STET), and seminal online web development texts are emerging. Publishing online is simple, far-reaching and immediate.

Much more so than articles and blog posts, books take time to research, write and read; add the complexity of commissioning, editing, designing, proofreading, printing, marketing and distribution processes, and it can take many months, even years to publish. The ceaseless headlong momentum of the web can leave articles more than a few weeks old whimpering in its wake, but updating them at least is straightforward; printed books about web development can depreciate as rapidly as the technology and techniques they describe, while retaining the “terrifying permanence that print bestows: your opinions will follow you forever”.

So much moves on, and becomes out of date. Companies featured get bought by larger companies and die, techniques improve and solutions featured become terribly out of date. Unlike a website, which could be updated continuously, a book represents the thinking ‘at that time’.
—Jon Hicks


Publishers work hard to mitigate these issues, promoting new books and new authors, bringing authors and readers together under a trusted banner. When a publisher packages up and releases a writer’s words, it confers a seal of approval and “badge of quality”, very important to new authors.

Publishers have other benefits to offer, from expert knowledge:

My publisher was extraordinarily supportive (and patient). Her expertise in my chosen subject was both a pressure (I didn’t want to let her down) and a reassurance (if she liked it, I knew it was going to be fine).
—Andrew Travers


…to systems and support mechanisms set up specifically to encourage writers and publish books:

Working as a team means you’re bringing in everyone’s expertise.
—Chui Chui Tan


As a writer, the best part about writing for a publisher was the writing infrastructure offered.
—Christopher Murphy


There can be drawbacks, however, and the occasional horror story:

We were just one small package on a huge conveyor belt. The publisher’s process ruled all.
—Cennydd Bowles


It’s only looking back I realise how poorly some publishers treat writers — especially when the work is so poorly remunerated.My worst experience was when a publisher decided, after I had completed the book, that they wanted to push a different take on the subject than the brief I had been given. Instead of talking to me, they rewrote chunks of my words, turning my advice into something that I would never have encouraged. Ultimately, I refused to let the book go out under my name alone, and I also didn’t really promote the book as I would have had to point out the things I did not agree with that had been inserted!
—Rachel Andrew


Self-publishing is now a realistic option for web authors, and can offers “complete control over the end product” as well as the possibility of earning more than a “pathetic author revenue percentage”. There can be substantial barriers, of course, as self-publishing authors must face for themselves the risks and challenges conventional publishers usually bear. Ideally, creating a book is a collaboration between author and publisher. Geri Coady found that “working with my publisher felt more like working with a partner or co-worker, rather than working for a boss.”

Wise words

So, after meeting the personal costs of writing and publishing a web book — fear, uncertainty, doubt, typing (so much typing) — and then smelling the roses of success, what’s left for an author to say? Some words, perhaps, to people thinking of writing a book.

Donna Spencer identifies a stumbling block common to many writers with an insight into the writing process:


	Having talked to a lot of potential authors, I think most have the problem that they haven’t actually figured out the ‘answer’ to their premise yet. They feel like they are stuck in the writing, but they are actually stuck in the thinking.


For some no-nonsense, straightforward advice to cut through any anxiety or inadequacy, Rachel Andrew encourages authors to “treat it like any other work. There is no mystery to writing, you just have to write. Schedule the time, sit down, write words.” Tim Brown notes the importance of the editing process to refine a book and help authors reach their readers:


	Hire good editors. Editors are amazing thinkers who can vastly improve the quality and clarity of a piece of writing.


We are too much beholden to the practical demands and challenges of technology, so Aaron Gustafson suggests a writer should “favor philosophies over techniques and your book will have a longer shelf life.”

Most intimations of renown and recognition are nipped in the bud by Joe Leech’s warning: “Don’t expect fame and fortune.” Although Cennydd Bowles’ bitter experience can be discouraging:


	The sacrifices required are immense. You probably won’t make it.


…he would do things differently for a future book:


	I would approach the book with […] far more concern about conveying the damn joy of what I do for a living.


The pleasure of writing, not just having written is captured by James Chudley when he recalls:


	How much I enjoy writing and also how much I enjoy the discipline or having a side project like this. It’s a really good supplement to working life.


And Jon Hicks has words that any author will find comforting:


	It will be fine. Everything will be fine. Just get on with it!




As the web expands effortlessly and ceaselessly to make room for all our words, yet it can also discourage the accumulation of any particular theme in one space, dividing rich seams and scattering knowledge across the web’s surface and into its deepest reaches. How many words become weightless and insubstantial, signals lost in the constant white noise of indistinguishable voices, unloved, unlinked? The web forgets constantly, despite the (somewhat empty) promise of digital preservation: articles and data are sacrificed to expediency, profit and apathy; online attention, acknowledgement and interest wax and wane in days, hours even.

Books can encourage deeper engagement in readers, and foster faith in an author, particularly if released under the imprint of a recognized publisher within the field. And books are changing. Although still not widely adopted, EPUB3 is the new standard in ebooks, bringing with it new possibilities for interaction and connection: readers with the text; readers with readers; and readers with authors. EPUB3 is built on HTML, CSS and JavaScript — sound familiar? In the past, we took what we could from the printed page to make the web; now books are rubbing up against what we’ve made.

So: a book.

Ever thought you could write one? Should write one? Would?



I’d like to thank all the authors who wrote their books and answered my questions.

16,URL Rewriting for the Fearful,"I think it was Marilyn Monroe who said, “If you can’t handle me at my worst, please just fix these rewrite rules, I’m getting an internal server error.” Even the blonde bombshell hated configuring URL rewrites on her website, and I think most of us know where she was coming from.

The majority of website projects I work on require some amount of URL rewriting, and I find it mildly enjoyable — I quite like a good rewrite rule. I suspect you may not share my glee, so in this article we’re going to go back to basics to try to make the whole rigmarole more understandable.

When we think about URL rewriting, usually that means adding some rules to an .htaccess file for an Apache web server. As that’s the most common case, that’s what I’ll be sticking to here. If you work with a different server, there’s often documentation specifically for translating from Apache’s mod_rewrite rules. I even found an automatic converter for nginx.

This isn’t going to be a comprehensive guide to every URL rewriting problem you might ever have. That would take us until Christmas. If you consider yourself a trial-and-error dabbler in the HTTP 500-infested waters of URL rewriting, then hopefully this will provide a little bit more of a basis to help you figure out what you’re doing. If you’ve ever found yourself staring at the white screen of death after screwing up your .htaccess file, don’t worry. As Michael Jackson once insipidly whined, you are not alone.

The basics

Rewrite rules form part of the Apache web server’s configuration for a website, and can be placed in a number of different locations as part of your virtual host configuration. By far the simplest and most portable option is to use an .htaccess file in your website root. Provided your server has mod_rewrite available, all you need to do to kick things off in your .htaccess file is:

RewriteEngine on

The general formula for a rewrite rule is:

RewriteRule URL/to/match URL/to/use/if/it/matches [options]

When we talk about URL rewriting, we’re normally talking about one of two things: redirecting the browser to a different URL; or rewriting the URL internally to use a particular file. We’ll look at those in turn.

Redirects

Redirects match an incoming URL, and then redirect the user’s browser to a different address. These can be useful for maintaining legacy URLs if content changes location as part of a site redesign. Redirecting the old URL to the new location makes sure that any incoming links, such as those from search engines, continue to work. 

In 1998, Sir Tim Berners-Lee wrote that Cool URIs don’t change, encouraging us all to go the extra mile to make sure links keep working forever. I think that sometimes it’s fine to move things around — especially to correct bad URL design choices of the past — provided that you can do so while keeping those old URLs working. That’s where redirects can help.

A redirect might look like this

RewriteRule ^article/used/to/be/here.php$ /article/now/lives/here/ [R=301,L]

Rewriting

By default, web servers closely map page URLs to the files in your site. On receiving a request for http://example.com/about/history.html the server goes to the configured folder for the example.com website, and then goes into the about folder and returns the history.html file.

A rewrite rule changes that process by breaking the direct relationship between the URL and the file system. “When there’s a request for /about/history.html” a rewrite rule might say, “use the file /about_section.php instead.”

This opens up lots of possibilities for creative ways to map URLs to the files that know how to serve up the page. Most MVC frameworks will have a single rule to rewrite all page URLs to one single file. That file will be a script which kicks off the framework to figure out what to do to serve the page.

RewriteRule ^for/this/url/$ /use/this/file.php [L] 

Matching patterns

By now you’ll have noted the weird ^ and $ characters wrapped around the URL we’re trying to match. That’s because what we’re actually using here is a pattern. Technically, it is what’s called a Perl Compatible Regular Expression (PCRE) or simply a regex or regexp. We’ll call it a pattern because we’re not animals.

What are these patterns? If I asked you to enter your credit card expiry date as MM/YY then chances are you’d wonder what I wanted your credit card details for, but you’d know that I wanted a two-digit month, a slash, and a two-digit year. That’s not a regular expression, but it’s the same idea: using some placeholder characters to define the pattern of the input you’re trying to match.

We’ve already met two regexp characters.


	^
	Matches the beginning of a string
	$
	Matches the end of a string


When a pattern starts with ^ and ends with $ it’s to make sure we match the complete URL start to finish, not just part of it. There are lots of other ways to match, too:


	[0-9]
	Matches a number, 0–9. [2-4] would match numbers 2 to 4 inclusive.
	[a-z]
	Matches lowercase letters a–z
	[A-Z]
	Matches uppercase letters A–Z
	[a-z0-9]
	Combining some of these, this matches letters a–z and numbers 0–9


These are what we call character groups. The square brackets basically tell the server to match from the selection of characters within them. You can put any specific characters you’re looking for within the brackets, as well as the ranges shown above. 

However, all these just match one single character. [0-9] would match 8 but not 84 — to match 84 we’d need to use [0-9] twice.

[0-9][0-9]

So, if we wanted to match 1984 we could to do this:

[0-9][0-9][0-9][0-9] 

…but that’s getting silly. Instead, we can do this:

[0-9]{4}

That means any character between 0 and 9, four times. If we wanted to match a number, but didn’t know how long it might be (for example, a database ID in the URL) we could use the + symbol, which means one or more.

[0-9]+

This now matches 1, 123 and 1234567.

Putting it into practice

Let’s say we need to write a rule to match article URLs for this website, and to rewrite them to use /article.php under the hood. The articles all have URLs like this:

2013/article-title/

They start with a year (from 2005 up to 2013, currently), a slash, and then have a URL-safe version of the article title (a slug), ending in a slash. We’d match it like this:

^[0-9]{4}/[a-z0-9-]+/$

If that looks frightening, don’t worry. Breaking it down, from the start of the URL (^) we’re looking for four numbers ([0-9]{4}). Then a slash — that’s just literal — and then anything lowercase a–z or 0–9 or a dash ([a-z0-9-]) one or more times (+), ending in a slash (/$).

Putting that into a rewrite rule, we end up with this:

RewriteRule ^[0-9]{4}/[a-z0-9-]+/$ /article.php

We’re getting close now. We can match the article URLs and rewrite them to use article.php. Now we just need to make sure that article.php knows which article it’s supposed to display.

Capturing groups, and replacements

When rewriting URLs you’ll often want to take important parts of the URL you’re matching and pass them along to the script that handles the request. That’s usually done by adding those parts of the URL on as query string arguments. For our example, we want to make sure that article.php knows the year and the article title we’re looking for. That means we need to call it like this:

/article.php?year=2013&slug=article-title

To do this, we need to mark which parts of the pattern we want to reuse in the destination. We do this with round brackets or parentheses. By placing parentheses around parts of the pattern we want to reuse, we create what’s called a capturing group. To capture an important part of the source URL to use in the destination, surround it in parentheses.

Our pattern now looks like this, with parentheses around the parts that match the year and slug, but ignoring the slashes:

^([0-9]{4})/([a-z0-9-]+)/$ 

To use the capturing groups in the destination URL, we use the dollar sign and the number of the group we want to use. So, the first capturing group is $1, the second is $2 and so on. (The $ is unrelated to the end-of-pattern $ we used before.)

RewriteRule ^([0-9]{4})/([a-z0-9-]+)/$ /article.php?year=$1&slug=$2 

The value of the year capturing group gets used as $1 and the article title slug is $2. Had there been a third group, that would be $3 and so on. In regexp parlance, these are called back-references as they refer back to the pattern.

Options

Several brain-taxing minutes ago, I mentioned some options as the final part of a rewrite rule. There are lots of options (or flags) you can set to change how the rule is processed. The most useful (to my mind) are:


	R=301
	Perform an HTTP 301 redirect to send the user’s browser to the new URL. A status of 301 means a resource has moved permanently and so it’s a good way of both redirecting the user to the new URL, and letting search engines know to update their indexes.
	L
	Last. If this rule matches, don’t bother processing the following rules.


Options are set in square brackets at the end of the rule. You can set multiple options by separating them with commas:

RewriteRule ^([0-9]{4})/([a-z0-9-]+)/$ /article.php?year=$1&slug=$2 [L]

or

RewriteRule ^about/([a-z0-9-]+).jsp/$ /about/$1/ [R=301,L] 

Common pitfalls

Once you’ve built up a few rewrite rules, things can start to go wrong. You may have been there: a rule which looks perfectly good is somehow not matching. One common reason for this is hidden behind that [L] flag. 

L for Last is a useful option to tell the rewrite engine to stop once the rule has been matched. This is what it does — the remaining rules in the .htaccess file are then ignored. However, once a URL has been rewritten, the entire set of rules are then run again on the new URL. If the new URL matches any of the rules, that too will be rewritten and on it goes. 

One way to avoid this problem is to keep your ‘real’ pages under a folder path that will never match one of your rules, or that you can exclude from the rewrite rules.

Useful snippets

I find myself reusing the same few rules over and over again, just with minor changes. Here are some useful examples to refer back to.

Excluding a directory

As mentioned above, if you’re rewriting lots of fancy URLs to a collection of real files it can be helpful to put those files in a folder and exclude it from rewrite rules. This helps solve the issue of rewrite rules reapplying to your newly rewritten URL. To exclude a directory, put a rule like this at the top of your file, before your other rules. Our files are in a folder called _source, the dash in the rule means do nothing, and the L flag means the following rules won’t be applied.

RewriteRule ^_source - [L]

This is also useful for excluding things like CMS folders from your website’s rewrite rules

RewriteRule ^perch - [L] 

Adding or removing www from the domain

Some folk like to use a www and others don’t. Usually, it’s best to pick one and go with it, and redirect the one you don’t want. On this site, we don’t use www.24ways.org so we redirect those requests to 24ways.org.

This uses a RewriteCond which is like an if for a rewrite rule: “If this condition matches, then apply the following rule.” In this case, it’s if the HTTP HOST (or domain name, basically) matches this pattern, then redirect everything:

RewriteCond %{HTTP_HOST} ^www.24ways.org$ [NC]
RewriteRule ^(.*)$ http://24ways.org/$1 [R=301,L]

The [NC] flag means ‘no case’ — the match is case-insensitive. The dots in the domain are escaped with a backslash, as a dot is a regular expression character which means match anything, so we escape it because we literally mean a dot in this instance.

Removing file extensions

Sometimes all you need to do to tidy up a URL is strip off the technology-specific file extension, so that /about/history.php becomes /about/history. This is easily achieved with the help of some more rewrite conditions.

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^(.+)$ $1.php [L,QSA]

This says if the file being asked for isn’t a file (!-f) and if it isn’t a directory (!-d) and if the file name plus .php is an actual file (-f) then rewrite by adding .php on the end. The QSA flag means ‘query string append’: append the existing query string onto the rewritten URL.

It’s these sorts of more generic catch-all rules that you need to watch out for when your .htaccess gets rerun after a successful match. Without care they can easily rematch the newly rewritten URL.

Logging for when it all goes wrong

Although not possible within your .htaccess file, if you have access to your Apache configuration files you can enable rewrite logging. This can be useful to track down where a rule is going wrong, if it’s matching incorrectly or failing to match. It also gives you an overview of the amount of work being done by the rewrite engine, enabling you to rearrange your rules and maximise performance.

RewriteEngine On
RewriteLog ""/full/system/path/to/rewrite.log""
RewriteLogLevel 5

To be doubly clear: this will not work from an .htaccess file — it needs to be added to the main Apache configuration files. (I sometimes work using MAMP PRO locally on my Mac, and this can be pasted into the snappily named Customized virtual host general settings box in the Advanced tab for your site.)

The white screen of death

One of the most frustrating things when working with rewrite rules is that when you make a mistake it can result in the server returning an HTTP 500 Internal Server Error. This in itself isn’t an error message, of course. It’s more of a notification that an error has occurred. The real error message can usually be found in your Apache error log.

If you have access to your server logs, check the Apache error log and you’ll usually find a much more descriptive error message, pointing you towards your mistake. (Again, if using MAMP PRO, go to Server, Apache and the View Log button.)

In conclusion

Rewriting URLs can be a bear, but the advantages are clear. Keeping a tidy URL structure, disconnected from the technology or file structure of your site can result in URLs that are easier to use and easier to maintain into the future.

If you’re redesigning a site, remember that cool URIs don’t change, so budget some time to make sure that any content you move has a rewrite rule associated with it to keep any links working.

12,Untangling Web Typography,"When I was a carpenter, I noticed how homeowners often had this deer-in-the-headlights look when the contractor I worked for would ask them to make tons of decisions, seemingly all at once.

Square or subway tile? Glass or ceramic? Traditional or modern trim details? Flat face or picture frame cabinets? Real wood or laminate flooring? Every day the decisions piled up and were usually made in the context of that room, or that part of that room. Rarely did the homeowner have the benefit of taking that particular decision in full view of the larger context of the project. And architectural plans? Sure, they lay out the broad strokes, but there is still so much to decide.

Typography is similar. Designers try to make sites that are easy to use and understand visually. They labour over the details of line height, font size, line length, and font weights. They consider the relative merits of different typographical scales for applications versus content-driven sites. Frequently, designers consider all of this in the context of one page, feature, or view of an application. They are asked to make a million tiny decisions.

Sometimes designers just bump up the font size until it looks right.

I don’t see anything wrong with that. Instincts are important. Designing in context is easier. It’s OK to leave the big picture until later. Design a bunch of things, and then look for the patterns. You can’t always know everything up front. How does the current feature relate to all the other features on the site? For a large site, just like for a substantial remodel, the number of decisions you would need to internalize to make that knowable would be prohibitively large.

When typography goes awry

I should be honest. I know very little about typography. I struggle to understand vertical rhythm and the math in Tim Ahrens’s talks about the interaction between type design and rendering technology kind of melted my brain. I have an unusual perspective because I’m not the one making the design decisions, but I am the one implementing them and often cleaning up when a project goes off the rails.

I’ve seen projects with thousands of font-size declarations and headings. One project even had over ten thousand margin declarations. So while I appreciate creative exploration, I’m also eager to establish patterns in typography and make sure we aren’t choosing not to choose. Or, choosing all the things.

Analyzing a site’s typography

Most of my projects start out with an evaluation of the client’s existing CSS. I look for duplication in the CSS by using Grep, though functionality is landing soon in CSS Lint to do the same thing automatically. The goal is to find the underlying missing abstractions that, once in place, would allow developers to create new functionality without needing to write additional CSS. In addition to that, my team and I would comb through each site (generally, around ten pages is enough to get the big picture), and take screenshots of each of the components we found.

In this way, we could look for subtle visual differences that were unlikely to add value to the user. By correcting these differences, we could help make the design more consistent, and at the same time the code leaner and more performant. Typography is much like a homeowner who chooses to incorporate too many disparate design elements, pairing a mid-century modern sofa with flowered country cottage curtains. Often the typography of a site ends up collecting an endless array of new typefaces as the site’s overall styles evolve. Designers come and go on a project, and eventually no one can remember how the 16px Verdana got into the codebase.

Automation

We used to do this work by hand. It was incredibly tedious. We’d go through the site, taking screenshots and meticulously documenting the style information we found. We didn’t have to do that many times before it became incredibly clear that the task needed to be automated. So we built a little tool called the Type-o-matic that could do it for us.

To try it on your site:


	Download and install the Firebug extension to Firefox
	Download and install the Type-o-matic extension to Firebug (I know, I fully intend to port it to Chrome)
	Now, visit the site you’d like to test
	Right click and choose Inspect element with Firebug
	Now click on the Typography tab
	Click Persist
	Click Generate Report
	Choose which pages to analyze (we’ve found that ten is a good number to get the big picture, but you can analyze as many as you’d like — it will even work on just one page!)
	Now navigate to other pages, and on each subsequent page, click Generate Report
	The table of results can be a bit difficult to interact with, so you can always click Copy to clipboard, and copy the results (JSON).

What does this data mean?

When you’ve analyzed as many pages or different views as you’d like, you’ll start to see some interesting patterns emerge in the data. In the right-hand column, you’ll see examples of how each kind of typography we found has been used in a real context on your site. It is organized by color and then by size so you can easily see how you are using typography.

The next thing you’ll want to take a look at is in the first column, called “Count”. We’ve counted how many times you’ve used each combination of typographical styles. This can be incredibly helpful when deciding which styles were intentional, versus one-off color pick errors or experiments that never got removed from the code base. If you’ve used one color blue 1,400 times, and another just 23, it’s pretty obvious which is more in line with broader site-wide styles.

Consistency before perfection

It can be really tempting to try to make everything perfect — to try to make every decision final. When you use the data you can collect from this tool, I’d recommend trying to get to consistent before you try to make things perfect. Stop using fifteen different shades of blue type first, and then if you want to change to a new blue, go for it! You’ll be able to make design changes much more easily once you’ve reduced the total number of typographical styles you rely on.

Lower the importance of the decisions you are making. Our sites, like ourselves, are always a work in progress. Or, as a carpenter I used to work with said, “You’re not building a fucking piano.” We’re not building houses. We can choose one typeface today and a different one tomorrow. It is OK to experiment.

22,The Responsive Hover Paradigm,"CSS transitions and animations provide web designers with a whole slew of tools to spruce up our designs. Move over ActionScript tweens! The techniques we can now implement with CSS are reminiscent of Flash-based adventures from the pages of web history.

Pairing CSS enhancements with our :hover pseudo-class allows us to add interesting events to our websites. We have a ton of power at our fingertips. However, with this power, we each have to ask ourselves: just because I can do something, should I?

Why bother? 

We hear a lot of mantras in the web community. Some proclaim the importance of content; some encourage methods like mobile first to support content; and others warn of the overhead and speed impact of decorative flourishes and visual images. I agree, one hundred percent. At the same time, I believe that content can reign king and still provide a beautiful design with compelling interactions and acceptable performance impacts. Maybe, just maybe, we can even have a little bit of fun when crafting these systems!

Yes, a site with pure HTML content and no CSS will load very fast on your mobile phone, but it leaves a lot to be desired. If you went to your local library and every book looked the same, how would you know which one to borrow? Imagine if every book was printed on the same paper stock with the same cover page in the same type size set at a legible point value… how would you know if you were going to purchase a cookbook about wild game or a young adult story about teens fighting to the death?

For certain audiences, seeing a site with hip, lively hovers sure beats a stale website concept. I’ve worked on many higher education sites, and setting the interactive options is often a very important factor in engaging potential students, alumni, and donors. The same can go for e-commerce sites: enticing your audience with surprise and delight factors can be the difference between a successful and a lost sale. 

Knowing your content and audience can help you decide if an intriguing experience is appropriate for your site; if it is, then hover responses can be a real asset. 

Why hover?

We have all these capabilities with CSS properties to create the aforementioned fun interactions, and it would be quite easy to fall back into some old patterns and animation abuse. The world of Flash intros and skip links could be recreated with CSS keyframes. However, I don’t think any of us want to go the route of forcing users into unwanted exchanges and road blocking content. 

What’s great about utilizing hover to pair with CSS powered actions is that it’s user initiated. It’s a well-established expectation that when a user mouses over an object, something changes. If we can identify that something as a link, then we will expect something to change as we move our mouse over it. By waiting to trigger a CSS-based response until a user chooses to engage with a target makes for a more polished experience (as opposed to barraging our screens with animations all willy-nilly). This makes it the perfect opportunity to add some unique spunk. 

What about mobile, touch, and responsive?

So, you’re on board with this so far, but what about mobile and touch devices? Sure, some devices like the Samsung Galaxy S4 have some hovering capabilities, but certainly most do not. Beyond mobile devices, we also have to worry about desktops with touch capabilities. It’s super difficult to detect if a user is currently using touch or hover. One option we have is to design strictly for touch only and send hover enhancements to the graveyard. However, being that I’m all “fuck yeah hovers!,” I like to explore all options. So, let’s examine four different types of hover patterns and see how they can translate to our touch devices.

1. The essential text hover

Changing text color on hover is something we’ve done for a while and it has helped aid in identifying links. To maintain the best accessibility we can achieve, it helps to have a different visual indicator on the default :link state, such as an underline. By making sure all text links have an underline, we won’t have to rely on visual changes during hover to make sure touch device users know that it is a link. For hover-enabled devices, we can add a basic color transition. Doing so creates a nice fade, which makes the change on hover less jarring. Kinda like smooth jazz. The code* to achieve this is quite simple: 

a {
	color: #6dd4b1;
	transition: color 0.25s linear;  
}

a:hover, a:focus  {
	color: #357099;
}


	Browser prefixes are omitted


You can see in the final result that, for both touch and hover, everyone wins:

2. Visual background wizardry and animated hovers

We can take this a step further by again making changes to our aesthetic on hover, but not making any content changes. Altering image hovers for fun and personality can separate your site from others; that personality is important and can enhance our content. 

Let’s look at a few sites that do this really well. Scroll down to the judges section of CSS Off and check out the illustrations of the judges. On hover, the illustration fades into a photo of the judge. This provides a realistic alternative to the drawing. Users without the hover can click into the detail page, where they can see the full color picture and learn more about the judges; the information is still available through a different pathway. 

Going back to the higher education field, let’s visit Delaware Valley College. The school had recently gone through a rebranding that included loop icons as a symbol to connect ideas. These icons are brought into the website on hover of the slideshow arrows (WebKit browsers). The hover reveals a loop animation, tying in overall themes and adding some extra pizzazz that makes me think, “This is a hip place that feels current.” For visitors who can’t access the hover effect, the default arrow state clearly represents a clickable link, and there is swipe functionality on mobile devices to boot. 

DIY.org’s Frontend Dev page has a bunch of enjoyable hover actions happening, featuring scaling transforms and looping animations. Nothing new is revealed on hover, so touch devices won’t miss anything, but it intrigues the user who is visiting a site about front-end dev doing cool front-end things. It backs up its claim of front-end knowledge by adding this enhancement. 

The old Cowork Chicago (now redirecting) had a great example, captured here:

 Coop: Chicago Coworking from Jenn Lukas on Vimeo.

The code for the Join areas is quite simple: 

.join-buttons .daily, .join-buttons .monthly { 
    height: 260px; z-index: 0; margin-top: 30px;
	transition: height .2s linear,margin .2s linear;
}

.join-buttons .daily:hover, .join-buttons .monthly:hover { 
	height: 280px; margin-top: 20px; 
}

li.button:hover { 
    z-index: 20; 
}

The slight rotation on the photos, and the change of color and size of the rate options on hover, add to the fun factor. The site attempts to advertise the co-working space by letting bits of their charisma show through with these transitions. They don’t hit the user over the head with animations, but provide a nice addition to make sure visitors know it’s a welcoming place to work. Some text is added on the hover, but the text isn’t essential to determine where the link goes.

3. Image block hovers

There have been more designs popping up with large image blocks acting as extensive hit area links to subsequent pages. On hover of these links, text is revealed, letting the user know where the link destination goes. 

See the Pen Transitioning Max Height by Jenn Lukas (@Jenn) on CodePen

This type of link is tough for users on touch as the image might not provide enough context to reveal its target. If you weren’t aware of what my illustrated avatar from 2007 looked like (or even if you did), then how would you know that this is a link to my Twitter page? Instead, if we provide  enough context — such as the @jennlukas handle — you could assume the destination. Users who receive the hover can also see the Twitter bio. It won’t break the experience for users that can’t hover, but it will provide a nice interaction and some more information for those that can. 

See the Pen Transitioning Max Height by Jenn Lukas (@Jenn) on CodePen

The Esquire site follows this same pattern, in which the title of the story is shown and the subheading is revealed on hover. Dining at Altitude took the opposite approach, where all text is shown by default and, on hover, you can see more of the image that the text sits atop. This is a nice technique to follow. For touch users, following the link will allow them to see more of the image detail that was revealed on hover. 

4. Drop-down navigation menu hovers

Main navigation options that rely on hover have come up as a problem for touch. One way to address this is to be sure your top level items are all functional links to somewhere, and not blank anchors to trigger a submenu drop-down. This ensures that, even without the hover-triggered menu, users can still navigate to those top-level pages. From there, they should be able to access the tertiary pages shown in the drop-down. Following this arrangement, drop-down menus act as a quick shortcut and aren’t necessary to the navigational structure. If the top navigation items are your most visited pages, this execution won’t hinder your visitors. 

If the information within the menu is vital, such as a lone account menu, another option is to show drop-down menus on click instead of hover. This pattern will allow both mouse and touch users to access the drop-downs. 

Why can’t we just detect hover?

This is a really tricky thing to do. Internet Explorer 10 on Windows 8 uses the aria-haspopup attribute to simulate hover on touch devices, but usually our audience stretches beyond that group. There’s been discussion around using Modernizr, but false positives have come with that. A W3C draft for Media Queries Level 4 includes a hover feature, but it’s not supported yet. Since some devices can hover and touch, should you rely on hover effects for those? Arguments have come up that users can be browsing your site with a mouse and then decide to switch to touch, or vice versa. That might be a large concern for you, or it might be an edge case that isn’t vital to your site’s success. 

For one site, I used mousemove and touchstart JavaScript events in order to detect if a visitor starts to browse the site with a mouse. The design initiates for touch users, showing all text on load, but as soon as a mouse movement occurs, the text becomes hidden and is then revealed on hover. 

See the Pen Detect Touch devices with mousemove and touchstart by Jenn Lukas (@Jenn) on CodePen

One downside to this approach is that the text is viewable until a mouse enters the document, but if the elements are further down the page it might not be noticed. A second downside is if a user on a touch- and hover-enabled device starts browsing with the mouse and then switches back to touch, the hover-centric styles will remain until a new page load. These were acceptable scenarios in the project I worked on, but might not be for every project. 

Can we give our visitors a choice?

I’ve been thinking about how we can combat the concern of not knowing if our customers are using touch or a mouse, not to mention keyboard or Wacom tablets or Minority Report screens. We can cover keyboards with our friend :focus, but that still doesn’t solve our other dilemmas. 

Remember when we couldn’t rely on browsers to zoom text and we had to use those small A, medium A, big A [AAA] buttons? On selection of one of those options, a different style sheet would load with small, medium, or large text sizes to satisfy our user’s request. We could even set cookies to remember their font choices. What if we offered a similar solution, a hover/touch switcher, for our new predicament? 

See the Pen cwuJf by Jenn Lukas (@Jenn) on CodePen

We could add this switcher to our design. Maybe add it to the header on smaller screens and the footer on larger screens to play the odds. Then be sure to deliver the appropriate touch- or hover-optimized adventure for our guests.

How about adding View options in the areas where we’re hiding content until hover? Looking at Delta Cycle, there’s logic in place to switch layouts on some mobile devices. On desktops we can see the layout shows the product and price by default, and the name of the item and an Add to cart button on hover. If you want to keep this hover, but also worry that touch users can’t access it — or even if you are concerned that people might want to view it with more details up front — we could add another view switcher. 

See the Pen List/Grid Views for Hover or Touch by Jenn Lukas (@Jenn) on CodePen

Similar to the list versus grid view we often see in operating systems, a choice here could cover all of our bases.  

Conclusion

There is no one-size-fits-all solution when it comes to hover patterns. Design for your content. If you are providing important information about driving directions or healthcare, you might want to err on the side of designing for touch only. If you are behind an educational site and trying to entice more traffic and sign-ups, or a more immersive e-commerce site selling pies, then hover activity can help support your content and engage your visitors without being a detriment. While content can be our top priority, let’s not forget that our designs and interactions, hovers included, can have a great positive impact on how visitors experience our site. Hover wisely, friends.",2013,Jenn Lukas,jennlukas,2013-12-12T00:00:00+00:00,https://24ways.org/2013/the-responsive-hover-paradigm/,
14,The Command Position Principle,"Living where I do, in a small village in rural North Wales, getting anywhere means driving along narrow country roads. Most of these are just about passable when two cars meet. 

If you’re driving too close to the centre of the road, when two drivers meet you stop, glare at each other and no one goes anywhere. Drive too close to your nearside and in summer you’ll probably scratch your paintwork on the hedgerows, or in winter you’ll sink your wheels into mud. 

Driving these lanes requires a balance between caring for your own vehicle and consideration for someone else’s, but all too often, I’ve seen drivers pushed towards the hedgerows and mud when someone who’s inconsiderate drives too wide because they don’t want to risk scratching their own paintwork or getting their wheels dirty.

If you learn to ride a motorcycle, you’ll be taught about the command position:


	Approximate central position, or any position from which the rider can exert control over invitation space either side.


The command position helps motorcyclists stay safe, because when they ride in the centre of their lane it prevents other people, usually car drivers, from driving alongside, either forcing them into the curb or potentially dangerously close to oncoming traffic. 

Taking the command position isn’t about motorcyclists being aggressive, it’s about them being confident. It’s them knowing their rightful place on the road and communicating that through how they ride.

I’ve recently been trying to take that command position when driving my car on our lanes. When I see someone coming in the opposite direction, instead of instinctively moving closer to my nearside — and in so doing subconsciously invite them into my space on the road — I hold both my nerve and a central position in my lane. Since I done this I’ve noticed that other drivers more often than not stay in their lane or pull closer to their nearside so we occupy equal space on the road. Although we both still need to watch our wing mirrors, neither of us gets our paint scratched or our wheels muddy.

We can apply this principle to business too, in particular to negotiations and the way we sell. Here’s how we might do that.

Commanding negotiations

When a customer’s been sold to well — more on that in just a moment — and they’ve made the decision to buy, the thing that usually stands in the way of us doing business is a negotiation over price. Some people treat negotiations as the equivalent of driving wide. They act offensively, because their aim is to force the other person into getting less, usually in return for giving more.

In encounters like this, it’s easy for us to act defensively. We might lack confidence in the price we ask for, or the value of the product or service we offer. We might compromise too early because of that. When that happens, there’s a pretty good chance that we’ll drive away with less than we deserve unless we use the command position principle to help us.

Before we start any negotiation it’s important to know that both sides ultimately want to reach an agreement. This isn’t always obvious. If one side isn’t already committed, at least in principle, then it’s not a negotiation at that point, it’s something else. 

For example, a prospective customer may be looking to learn our lowest price so that they can compare it to our competitors. When that’s the case, we’ve probably failed to qualify that prospect properly as, after all, who wants to be chosen simply because they’re the cheapest? In this situation, negotiating is a waste of time since we don’t yet know that it will result in us making a deal. We should enter into a negotiation only when we know where we stand. So ask confidently: “Are you looking to [make a decision]?”

When that’s been confirmed, it’s down to everyone to compromise until a deal’s been reached. That’s because good negotiations aren’t about one side beating the other, they’re about achieving a good deal for both. Using the command position principle helps us to maintain control over our negotiating space and affords us the opportunity to give ground only if we need to and only when we’re ready. It can also ensure that the person we’re negotiating with gives up some of their space.

Commanding sales

It’s not always necessary to negotiate when we’re doing a business deal, but we should always be prepared to sell. One of the most important parts of our sales process should be controlling when and how we tell someone our price. 

Unless it’s impossible to avoid, don’t work out a price for someone on the spot. When we do that we lose control over the time and place for presenting our price alongside the value factors that will contribute to the prospective customer accepting that price. For the same reason, never give a ballpark or, worse, a guesstimate figure. If the question of price comes up before we’re fully prepared, we should say politely that we need more time to work out a meaningful cost. 

When we are ready, we shouldn’t email a price for our prospective customer to read unaccompanied. Instead, create an opportunity to talk a prospect through our figures, demonstrate how we arrived at them and, most importantly, explain the value of what we’re selling to their business. Agree a time and place to do this and, if possible, do it all face-to-face.  

We shouldn’t hesitate when we give someone a price. When we sound even the slightest bit unsure or apologetic, we give the impression that we’ll be flexible in our position before negotiations have even begun.

Think about the command position principle, know the price and present it confidently. That way we send a clear signal that we know our business and how we deal with people. The command position principle isn’t about being cocky, it’s about showing other people respect, asking for it in return and showing it to ourselves.

 

Earlier, I mentioned selling well, because we sometimes hear people say that they dislike being sold to. In my experience, it’s not that people dislike the sales process, it’s that we dislike it done badly.

Taking part in a good sales process, either by selling or being sold to, can be a pleasurable experience. Try to be confident — after all, we understand how our skills will benefit a customer better than anyone else. Our confidence will inspire confidence in others. 

Self-confidence isn’t the same as arrogance, just as the command position isn’t the same as riding without consideration for others. The command position principle preserves others’ space as well as our own. By the same token, we should be considerate of others’ time and not waste it and our own by attempting to force them into buying something that’s inappropriate.

To prevent this from happening, evaluate them well to ensure that they’re the right customer for us. If they’re not, let them go on their way. They’ll thank us for it and may well become customers the next time we meet.

The business of closing a deal can be made an enjoyable experience for everyone if we take control by guiding someone through the sales process by asking the right questions to uncover their concerns, then allaying them by being knowledgeable and confident. This is riding in the command position.

Just like demonstrating we know our rightful position on the road, knowing our rightful place in a business relationship and communicating that through how we deal with people will help everyone achieve an equitable balance. When that happens in business, as well as on the road, no one gets their paintwork scratched or their wheels muddy.",2013,Andy Clarke,andyclarke,2013-12-23T00:00:00+00:00,https://24ways.org/2013/the-command-position-principle/,business
6,Run Ragged,"You care about typography, right? Do you care about words and how they look, read, and are understood? If you pick up a book or magazine, you notice the moment something is out of place: an orphan, rivers within paragraphs of justified prose, or caps masquerading as small caps. So why, I ask you, is your stance any different on the web?

We’re told time and time again that as a person who makes websites we have to get comfortable with our lack of control. On the web, this is a feature, not a bug. But that doesn’t mean we have to lower our standards, or not strive for the same amount of typographic craft of our print-based cousins. We shouldn’t leave good typesetting at the door because we can’t control the line length.

When I typeset books, I’d spend hours manipulating the text to create a pleasurable flow from line to line. A key aspect of this is manicuring the right rag — the vertical line of words on ranged-left text. Maximising the space available, but ensuring there are no line breaks or orphaned words that disrupt the flow of reading. Setting a right rag relies on a bunch of guidelines — or as I was first taught to call them, violations! 

Violation 1. Never break a line immediately following a preposition

Prepositions are important, frequently used words in English. They link nouns, pronouns and other words together in a sentence. And links should not be broken if you can help it. Ending a line on a preposition breaks the join from one word to another and forces the reader to work harder joining two words over two lines.

For example: 


	The container is for the butter


The preposition here is for and shows the relationship between the butter and the container. If this were typeset on a line and the line break was after the word for, then the reader would have to carry that through to the next line. The sentence would not flow.

There are lots of prepositions in English – about 150 – but only 70 or so in use.

Violation 2. Never break a line immediately following a dash

A dash — either an em-dash or en-dash — can be used as a pause in the reading, or as used here, a point at which you introduce something that is not within the flow of the sentence. Like an aside. Ending with a pause on the end of the line would have the same effect as ending on a preposition. It disrupts the flow of reading.

Violation 3. No small words at the end of a line

Don’t end a line with small words. Most of these will actually be covered by violation №1. But there will be exceptions. My general rule of thumb here is not to leave words of two or three letters at the end of a line.

Violation 4. Hyphenation

In print, hyphens are used at the end of lines to join words broken over a line break. Mostly, this is used in justified body text, and no doubt you will be used to seeing it in newspapers or novels. A good rule of thumb is to not allow more than two consecutive lines to end with a hyphen.

On the web, of course, we can use the CSS hyphens property. It’s reasonably supported with the exception of Chrome. Of course, it works best when combined with justified text to retain the neat right margin.

Violation 5. Don’t break emphasised phrases of three or fewer words

If you have a few words emphasised, for example:


	He calls this problem definition escalation


…then try not to break the line among them. It’s important the reader reads through all the words as a group.

How do we do all of that on the web?

All of those guidelines are relatively easy to implement in print. But what about the web? Where content is poured into a template from a CMS? Well, there are things we can do. Meet your new friend, the non-breaking space, or as you may know them:  .

The guidelines above are all based on one decision for the typesetter: when should the line break? 

We can simply run through a body of text and add the   based on these sets of questions:


	Are there any prepositions in the text? If so, add a   after them.
	Are there any dashes? If so, add a   after them.
	Are there any words of fewer than three characters that you haven’t already added spaces to? If so, add a   after them.
	Are there any emphasised groups of words either two or three words long? If so, add a   in between them.


For a short piece of text, this isn’t a big problem. But for longer bodies of text, this is a bit arduous. Also, as I said, lots of websites use a CMS and just dump the text into a template. What then? We can’t expect our content creators to manually manicure a right rag based on these guidelines. In this instance, we really need things to be automatic.

There isn’t any reason why we can’t just pass the question of when to break the line straight to the browser by way of a script which compares the text against a set of rules. In plain English, this script could be to scan the text for:


	Prepositions. If found, add   after them.
	Dashes. If found, add   after them.
	Words fewer than three characters long that aren’t prepositions. If found, add   after them.
	Emphasised phrases of up to three words in length. If found, add   between all of the words.


And there we have it.

A note on fluidity

An important consideration of this script is that it doesn’t scan the text to see what is at the end of a line. It just looks for prepositions, dashes, words fewer than three characters long, and emphasised words within paragraphs and applies the   accordingly regardless of where the thing lives. This is because in a fluid layout a word might appear in the beginning, middle or the end of a line depending on the width of the browser. And we want it to behave in the right way when it does find itself at the end.

See it in action!

My friend and colleague, Nathan Ford, has written a small JavaScript called Ragadjust that does all of this automatically. The script loops through a webpage, compares the text against the conditions, and then inserts   in the places that violate the conditions above.

You can get the script from GitHub and see it in action on my own website.

Some caveats

As my friend Jon Tan says, “There are no rules in typography, just good or bad decisions”, and typesetting the right rag is no different. 


	The guidelines for the violations above are useful for justified text, too. But we need to be careful here. Too stringent adherence to these violations could lead to ugly gaps in our words — called rivers — as the browser forces justification.
	The violation regarding short words at the end of sentences is useful for longer line lengths, or measures, of text. When the measure gets shorter, maybe five or six words, then we need to be more forgiving as to what wraps to the next line and what doesn’t. In fact, you can see this happening on my site where I’ve not included a check on the size of the browser window (purposefully, for this demo, of course. Ahem).
	This article is about applying these guidelines to English. Some of them will, no doubt, cross over to other languages quite well. But for those languages, like German for instance, where longer words tend to be in more frequent use, then some of the rules may result in a poor right rag.


Marginal gains

In 2007, I spoke with Richard Rutter at SXSW on web typography. In that talk, Richard and I made a point that good typographic design — on the web, in print; anywhere, in fact — relies on small, measurable improvements across an entire body of work. From heading hierarchy to your grid system, every little bit helps. In and of themselves, these little things don’t really mean that much. You may well have read this article, shrugged your shoulders and thought, “Huh. So what?” But these little things, when added up, make a difference. A difference between good typographic design and great typographic design.

This is only a slightly exaggerated version of my experience in design review meetings. 

The design project dance is a sloppy one. It involves a slew of email attachments, PDFs, PSDs, revisions, GitHub repos, staging environments, and more. And while tools like Basecamp can help manage all these moving parts, it can still be incredibly challenging to extract only the important bits, juggle deliverables, and see how your project is progressing.

Enter project hubs. 

Project hubs

A project hub consolidates all the key design and development materials onto a single webpage presented in reverse chronological order. The timeline lives online (either publicly available or password protected), so that everyone involved in the team has easy access to it.

 A project hub.

I was introduced to project hubs after seeing Dan Mall’s open redesign of Reading Is Fundamental. Thankfully, I had a chance to work with Dan on two projects where I got to see firsthand how beneficial a project hub can be. Here’s what makes a project hub great:


	Serves as a centralized home base for the project
	Trains clients and teams to decide in the browser
	Easily and visually view project’s progress
	Provides an archive for project artifacts


A home base

Your clients and colleagues can expect to get the latest and greatest updates to your project when visiting the project hub, the same way you’d expect to get the latest information on a requested topic when you visit a Wikipedia page. That’s the beauty of URIs that don’t change. 

Creating a project hub reduces a ton of email volley nonsense, and eliminates the need to produce files and directories with staggeringly ridiculous names like design/12.13.13/team/brian/for_review/_FINAL/styletile_121313_brian-edits-final_v2_FINAL.pdf. The team can simply visit the project hub’s URL and click the link to whatever artifact they need. Need to make an update? Simply update the link on the project hub. No more email tango and silly file names. 

Deciding in the browser


	Let’s change the phrase “designing in the browser” to “deciding in the browser.”
Dan Mall


We make websites, but all too often we find ourselves looking at web design artifacts in abstractions. We email PDFs to each other, glance at mockup JPGs on our desktops, and of course kill trees in order to print out designs so that we can scribble in the margins. All of these practices subtly take everyone further and further away from the design’s eventual final resting place: the browser.

Because a project hub is just a simple webpage, reviewing designs is as easy as clicking some links, which keep your clients and teams in the browser. 

You can keep people in the browser with yet another clever trick from the wily Dan Mall: instead of sending clients PDFs or JPGs, he created a simple webpage and tossed his static visuals into the template (you can view an example here). This forces clients to review web design work in the browser rather than launching a PDF viewer or Preview. 

Now this all might sound trivial to you (“Of course my client knows that we’re designing a website!”), but keeping the design artifacts in the browser subconsciously helps remind everyone of the medium for which you’re designing, which helps everyone focus on the right aspects of the design and have the right conversations. 

Progress over time

When you’re in the trenches, it’s often hard to visualize how a project is progressing. Tools like Basecamp include discussions, files, to-dos, and more, which are all great tools but also make things a bit noisy. Project hubs provide you and your clients a quick and easy way to see at a glance how things are coming along. Teams can rest assured they’re viewing the most current versions of designs, and managers can share progress with stakeholders simply by providing a link to the project hub. 

Over time, a project hub becomes an easily accessible archive of all the design decisions, which makes it easy to compare and contrast different versions of designs and prototypes.

Setting up a project hub

Setting up your own project hub is pretty simple. Simply create a webpage with some basic styles and branding. I’ve created a project hub template that’s available on GitHub if you want a jump-start.

Publish the webpage to a URL somewhere that makes sense (we’ve found that a subdomain of your site works quite well) and share it with everyone involved in the project. Bookmark it. Let everyone know that this is where design updates will be shared, and that they can always come back to the project hub to track the project’s progress.

When it comes time to share new updates, simply add a new node to the timeline and republish the webpage. Simple FTPing works just fine, but it might make sense to keep track of changes using version control. Our project hub for our open redesign of the Pittsburgh Food Bank is managed on GitHub, which means that I can make edits to the hub right from GitHub. Thanks to the magical wizardry of webhooks, I can automatically deploy the project hub so that everything stays in sync. That’s the fancy-pants way to do it, and is certainly not a requirement. As long as you’re able to easily make edits and keep your project hub up to date, you’re good to go. 

So that’s the hubbub

Project hubs can help tame the chaos of the design process by providing a home base for all key design and development materials. Keep the design artifacts in the browser and give clients and colleagues quick insight into your project’s progress.

5,Managing a Mind,"On 21 May 2013, I woke in a hospital bed feeling exhausted, disorientated and ashamed. The day before, I had tried to kill myself.

It’s very hard to write about this and share it. It feels like I’m opening up the deepest recesses of my soul and laying everything bare, but I think it’s important we share this as a community. Since starting tentatively to write about my experience, I’ve had many conversations about this: sharing with others; others sharing with me. I’ve been surprised to discover how many people are suffering similarly, thinking that they’re alone. They’re not.

Due to an insane schedule of teaching, writing, speaking, designing and just generally trying to keep up, I reached a point where my buffers completely overflowed. I was working so hard on so many things that I was struggling to maintain control. I was living life on fast-forward and my grasp on everything was slowly slipping.

On that day, I reached a low point – the lowest point of my life – and in that moment I could see only one way out. I surrendered. I can’t really describe that moment. I’m still grappling with it. All I know is that I couldn’t take it any more and I gave up.

I very nearly died.

I’m very fortunate to have survived. I was admitted to hospital, taken there unconscious in an ambulance. On waking, I felt overwhelmed with shame and overcome with remorse, but I was resolved to grasp the situation and address it. The experience has forced me to confront a great deal of issues in my life; it has also encouraged me to seek a deeper understanding of my situation and, in particular, the mechanics of the mind.

The relentless pace of change

We work in a fast-paced industry: few others, if any, confront the daily challenges we face. The landscape we work within is characterised by constant flux. It’s changing and evolving at a rate we have never experienced before. Few industries reinvent themselves yearly, monthly, weekly… Ours is one of these industries. Technology accelerates at an alarming rate and keeping abreast of this change is challenging, to say the least.

As designers it can be difficult to maintain a knowledge bank that is relevant and fit for purpose. We’re on a constant rollercoaster of endless learning, trying to maintain the pace as, daily, new ideas and innovations emerge — in some cases fundamentally changing our medium.

Under the pressure of client work or product design and development, it can be difficult to find the time to focus on learning the new skills we need to remain relevant and functionally competent. The result, all too often, is that the edges of our days have eroded. We no longer work nine to five; instead we work eight to six, and after the working day is over we regroup to spend our evenings learning. It’s an unsustainable situation.

From the workshop to the web

Added to this pressure to keep up, our work is now undertaken under a global gaze, conducted under an ever-present spotlight. Tools like Dribbble, Twitter and others, while incredibly powerful, have an unfortunate side effect, that of unfolding your ideas in public. This shift, from workshop to web, brings with it additional pressure.

In the past, the early stages of creativity took place within the relative safety of the workshop, an environment where one could take risks and gather feedback from a trusted few. We had space to make and space to break. No more. Our industry’s focus (and society’s focus) on sharing, leads us now to play out our decisions in public. This shift has changed us culturally, slowly but surely easing every aspect of our process – and lives – from private to public. This is at once liberating and debilitating.

If you’re not careful, an addiction to followers, likes, retweets, page views and other forms of measurement can overwhelm you. When you release your work into the wild and all it’s greeted with is silence, it can cripple you.

Reflecting on this, in an insightful article titled Derailed, Rogie King asks, “Can social popularity take us off the course of growth and where we were intended to go?” He makes a powerful point, that perhaps we might focus on what really matters, setting aside statistics. He concludes that to grow as practitioners we might be best served by seeking out critique through other avenues, away from the social spotlight.

On status anxiety and impostor syndrome

Following my experience I embarked on a period of self-reflection. I wanted to discover what had driven me to take the course of action I had. I wanted to ensure it never happened again. I wanted to understand how the mind works and, in so doing, learn a little more about myself.

I’ve only begun this journey, but two things I discovered resonated with me: the twin pressures of status anxiety and impostor syndrome.

In his excellent book Status Anxiety, the philosopher Alain de Botton explores a growing concern with status anxiety, a worry about how others perceive us and how this shapes our relationship with the world. He states:


	We all worry about what others think of us. We all long to succeed and fear failure. We all suffer – to a greater or lesser degree, usually privately and with embarrassment – from status anxiety. […] This is an almost universal anxiety that rarely gets mentioned directly: an anxiety about what others think of us; about whether we’re judged a success or a failure, a winner or a loser.


We see these pressures played out and amplified in the social sphere we all inhabit. We are social animals and we cannot help but react to the landscape we live and work within. Even if your work receives the public praise you so secretly desire, you find yourself questioning this praise.

A psychological phenomenon in which sufferers are unable to internalise their accomplishments, impostor syndrome is far more widespread than you’d imagine. The author Leigh Buchanan describes it as “A fear that one is not as smart or capable as others think.” As she puts it, “People who feel like frauds chalk up their accomplishments to external factors such as luck and timing, or worry they are coasting on charm and personality rather than on talent.”

At the bottom, this was all I could see. I felt overwhelmed by others’ perception of me. Was I a success or a failure? Would I be discovered as the fraud I’d convinced myself that I was? These twin pressures – that I was unconscious of at the time – had lead me to a place of crippling self-doubt, questioning my very existence.

The act of discovery, of investigating how the mind functions, led me to a deeper understanding of myself. Developing an awareness of psychology and learning about conditions like status anxiety and impostor syndrome helped me to understand and recognise how my mind worked, enabling me to manage it more effectively.



Make it count

Reflecting upon my experience, I began to regroup, to focus on what really mattered. I’d taken on too much — as I believe many of us do. I was guilty of wanting to do all the things. I started to introduce pauses. Before blindly saying yes to everything, I forced myself to pause and ask: “Is this important?”

Our community offers us huge benefits, but an always-on culture in which we’re bombarded daily by opportunity places temptation in our paths. It’s easy to get sucked in to a vortex of wanting to be a part of everything. It’s important, however, to focus. As Simon Collison puts it:


	I cull and surrender topics. Then I focus on my strengths, mastering my core skills.


We only have so much time and we can only do so much. It’s impossible, indeed futile, to try to do everything. Sometimes we need to step back a little and just enjoy life, enjoy others’ achievements, without feeling the need to be actively involved ourselves.

As Mahatma Ghandi put it:

A ‘no’ uttered from deepest conviction is better and greater than a ‘yes’ merely uttered to please, or what is worse, to avoid trouble.
Young India, volume 9, 1927


We need to learn to say no a little more often. We need to focus on the work that matters. This, coupled with an understanding of the mind and how it works, can help us achieve a happier balance between work and life.

Don’t waste your time. You only have one life. Make it count.",2013,Christopher Murphy,christophermurphy,2013-12-21T00:00:00+00:00,https://24ways.org/2013/managing-a-mind/,process
20,Make Your Browser Dance,"It was a crisp winter’s evening when I pulled up alongside the pier. I stepped out of my car and the bitterly cold sea air hit my face. I walked around to the boot, opened it and heaved out a heavy flight case. I slammed the boot shut, locked the car and started walking towards the venue.

This was it. My first gig. I thought about all those weeks of preparation: editing video clips, creating 3-D objects, making coloured patterns, then importing them all into software and configuring effects to change as the music did; targeting frequency, beat, velocity, modifying size, colour, starting point; creating playlists of these… and working out ways to mix them as the music played.

This was it. This was me VJing.

This was all a lifetime (well a decade!) ago.

When I started web designing, VJing took a back seat. I was more interested in interactive layouts, semantic accessible HTML, learning all the IE bugs and mastering the quirks that CSS has to offer. More recently, I have been excited by background gradients, 3-D transforms, the @keyframe directive, as well as new APIs such as getUserMedia, indexedDB, the Web Audio API

But wait, have I just come full circle? Could it be possible, with these wonderful new things in technologies I am already familiar with, that I could VJ again, right here, in a browser?

Well, there’s only one thing to do: let’s try it!

Let’s take to the dance floor 

Over the past couple of years working in The Lab I have learned to take a much more iterative approach to projects than before. One of my new favourite methods of working is to create a proof of concept to make sure my theory is feasible, before going on to create a full-blown product. So let’s take the same approach here.

The main VJing functionality I want to recreate is manipulating visuals in relation to sound. So for my POC I need to create a visual, with parameters that can be changed, then get some sound and see if I can analyse that sound to detect some data, which I can then use to manipulate the visual parameters. Easy, right?

So, let’s start at the beginning: creating a simple visual. For this I’m going to create a CSS animation. It’s just a funky i element with the opacity being changed to make it flash.

 See the Pen Creating a light by Rumyra (@Rumyra) on CodePen

A note about prefixes: I’ve left them out of the code examples in this post to make them easier to read. Please be aware that you may need them. I find a great resource to find out if you do is caniuse.com. You can also check out all the code for the examples in this article

Start the music

Well, that’s pretty easy so far. Next up: loading in some sound. For this we’ll use the Web Audio API. The Web Audio API is based around the concept of nodes. You have a source node: the sound you are loading in; a destination node: usually the device’s speakers; and any number of processing nodes in between. All this processing that goes on with the audio is sandboxed within the AudioContext.

So, let’s start by initialising our audio context.

var contextClass = window.AudioContext;
if (contextClass) {
  //web audio api available.
  var audioContext = new contextClass();
} else {
  //web audio api unavailable
  //warn user to upgrade/change browser
}

Now let’s load our sound file into the new context we created with an XMLHttpRequest.

function loadSound() {
	//set audio file url
	var audioFileUrl = '/octave.ogg';
	//create new request
	var request = new XMLHttpRequest();
	request.open(""GET"", audioFileUrl, true);
	request.responseType = ""arraybuffer"";

	request.onload = function() {
		//take from http request and decode into buffer
		context.decodeAudioData(request.response, function(buffer) {
	    	audioBuffer = buffer;
	     });
		}
	request.send();
}

Phew! Now we’ve loaded in some sound! There are plenty of things we can do with the Web Audio API: increase volume; add filters; spatialisation. If you want to dig deeper, the O’Reilly Web Audio API book by Boris Smus is available to read online free.

All we really want to do for this proof of concept, however, is analyse the sound data. To do this we really need to know what data we have.

 Learning the steps

Let’s take a minute to step back and remember our school days and science class. I’m sure if I drew a picture of a sound wave, we would all start nodding our heads.

 

The sound you hear is caused by pressure differences in the particles in the air. Sound pushes these particles together, causing vibrations. Amplitude is basically strength of pressure. A simple example of change of amplitude is when you increase the volume on your stereo and the output wave increases in size.

This is great when everything is analogue, but the waveform varies continuously and it’s not suitable for digital processing: there’s an infinite set of values. For digital processing, we need discrete numbers.

We have to sample the waveform at set time intervals, and record data such as amplitude and frequency. Luckily for us, just the fact we have a digital sound file means all this hard work is done for us. What we’re doing in the code above is piping that data in the audio context. All we need to do now is access it.

We can do this with the Web Audio API’s analysing functionality. Just pop in an analysing node before we connect the source to its destination node.

function createAnalyser(source) {
	//create analyser node
	analyser = audioContext.createAnalyser();
	//connect to source
	source.connect(analyzer);
	//pipe to speakers
	analyser.connect(audioContext.destination);
}

The data I’m really interested in here is frequency. Later we could look into amplitude or time, but for now I’m going to stick with frequency.

The analyser node gives us frequency data via the getFrequencyByteData method.

 Don’t forget to count!

To collect the data from the getFrequencyByteData method, we need to pass in an empty array (a JavaScript typed array is ideal). But how do we know how many items the array will need when we create it?

This is really up to us and how high the resolution of frequencies we want to analyse is. Remember we talked about sampling the waveform; this happens at a certain rate (sample rate) which you can find out via the audio context’s sampleRate attribute. This is good to bear in mind when you’re thinking about your resolution of frequencies.

var sampleRate = audioContext.sampleRate;

Let’s say your file sample rate is 48,000, making the maximum frequency in the file 24,000Hz (thanks to a wonderful theorem from Dr Harry Nyquist, the maximum frequency in the file is always half the sample rate). The analyser array we’re creating will contain frequencies up to this point. This is ideal as the human ear hears the range 0–20,000hz.

So, if we create an array which has 2,400 items, each frequency recorded will be 10Hz apart. However, we are going to create an array which is half the size of the FFT (fast Fourier transform), which in this case is 2,048 which is the default. You can set it via the fftSize property.

//set our FFT size
analyzer.fftSize = 2048;
//create an empty array with 1024 items
var frequencyData = new Uint8Array(1024);

So, with an array of 1,024 items, and a frequency range of 24,000Hz, we know each item is 24,000 ÷ 1,024 = 23.44Hz apart.

The thing is, we also want that array to be updated constantly. We could use the setInterval or setTimeout methods for this; however, I prefer the new and shiny requestAnimationFrame.

function update() {
  	//constantly getting feedback from data
  	requestAnimationFrame(update);
  	analyzer.getByteFrequencyData(frequencyData);
}

 Putting it all together

Sweet sticks! Now we have an array of frequencies from the sound we loaded, updating as the sound plays. Now we want that data to trigger our animation from earlier.

We can easily pause and run our CSS animation from JavaScript:

element.style.webkitAnimationPlayState = ""paused"";
element.style.webkitAnimationPlayState = ""running"";

Unfortunately, this may not be ideal as our animation might be a whole heap longer than just a flashing light. We may want to target specific points within that animation to have it stop and start in a visually pleasing way and perhaps not smack bang in the middle.

There is no really easy way to do this at the moment as Zach Saucier explains in this wonderful article. It takes some jiggery pokery with setInterval to try to ascertain how far through the CSS animation you are in percentage terms.

This seems a bit much for our proof of concept, so let’s backtrack a little. We know by the animation we’ve created which CSS properties we want to change. This is pretty easy to do directly with JavaScript.

element.style.opacity = ""1"";
element.style.opacity = ""0.2"";

So let’s start putting it all together. For this example I want to trigger each light as a different frequency plays. For this, I’ll loop through the HTML elements and change the opacity style if the frequency gain goes over a certain threshold.

//get light elements
var lights = document.getElementsByTagName('i');
var totalLights = lights.length;

for (var i=0; i<totalLights; i++) {
  //get frequencyData key
  var freqDataKey = i*8;
	//if gain is over threshold for that frequency animate light
  if (frequencyData[freqDataKey] > 160){
    //start animation on element
    lights[i].style.opacity = ""1"";
  } else {
    lights[i].style.opacity = ""0.2"";
  }
}

See all the code in action here. I suggest viewing in a modern browser :)

Awesome! It is true — we can VJ in our browser!

Let’s dance!

So, let’s start to expand this simple example. First, I feel the need to make lots of lights, rather than just a few. Also, maybe we should try a sound file more suited to gigs or clubs.

Check it out!

I don’t know about you, but I’m pretty excited — that’s just a bit of HTML, CSS and JavaScript!

The other thing to think about, of course, is the sound that you would get at a venue. We don’t want to load sound from a file, but rather pick up on what is playing in real time. The easiest way to do this, I’ve found, is to capture what my laptop’s mic is picking up and piping that back into the audio context. We can do this by using getUserMedia.

Let’s include this in this demo. If you make some noise while viewing the demo, the lights will start to flash.

 And relax :)

There you have it. Sit back, play some music and enjoy the Winamp like experience in front of you.

So, where do we go from here? I already have a wealth of ideas. We haven’t started with canvas, SVG or the 3-D features of CSS. There are other things we can detect from the audio as well. And yes, OK, it’s questionable whether the browser is the best environment for this. For one, I’m using a whole bunch of nonsensical HTML elements (maybe each animation could be held within a web component in the future). But hey, it’s fun, and it looks cool and sometimes I think it’s OK to just dance.",2013,Ruth John,ruthjohn,2013-12-02T00:00:00+00:00,https://24ways.org/2013/make-your-browser-dance/,code
2,Levelling Up,"Hello, 24 ways. I’m Ashley and I sell property insurance. I’m interrupting your Christmas countdown with an article about rental property software and a guy, Pete, who selflessly encouraged me to build my first web app. It doesn’t sound at all festive, or — considering I’ve used both “insurance” and “rental property” — interesting, but do stick with me. There’s eggnog at the end.

I run a property insurance business, Brokers Direct. It’s a small operation, but well established. We’ve been selling landlord insurance on the web for over thirteen years, for twelve of which we have provided our clients with third-party software for managing their rental property portfolios. Free. Of. Charge.

It sounds like a sweet deal for our customers, but it isn’t. At least, not any more. The third-party software is victim to years of neglect by its vendor. Its questionable interface, garish visuals and, ahem, clip art icons have suffered from a lack of updates. While it was never a contender for software of the year, I’ve steadily grown too embarrassed to associate my business with it.

 The third-party rental property software we distributed

I wanted to offer my customers a simple, clean and lightweight alternative. In an industry that’s dominated by dated and bloated software, it seemed only logical that I should build my own rental property tool.

The long learning-to-code slog

Learning a programming language is daunting, the source of my frustration stemming from a non-programming background. Generally, tutorials assume a degree of familiarity with programming, whether it be tools, conventions or basic skills. I had none and, at the time, there was nothing on the web really geared towards a novice. I reached the point where I genuinely thought I was just not cut out for coding. Surrendering to my feelings of self-doubt and frustration, I sourced a local Rails developer, Pete, to build it for me.

Pete brought a pack of index cards to our meeting. Index cards that would represent each feature the rental property software would launch with.

 

“OK,” he began. “We’ll need a user model, tenant model, authentication, tenant and property relationships…” A dozen index cards with a dozen features lined the coffee table in a grid-like format. Logical, comprehensible, achievable. Seeing the app laid out in a digestible manner made it seem surmountable. Maybe I could do this.

“I’ve been trying to learn Rails…”, I piped up.

I don’t know why I said it. I was fully prepared to hire Pete to do the hard work for me. But Pete, unprompted, gathered the index cards and neatly stacked them together, coasting them across the table towards me. “You should build this”.

Pete, a full-time freelance developer at the time, was turning down a paying job in favour of encouraging me to learn to code. Looking back, I didn’t realise how significant this moment was.

That evening, I took Pete’s index cards home to make a start on my app, slowly evolving each of the cards into a working feature. Building the app solo, I turned to Stack Overflow to solve the inevitable coding hurdles I encountered, as well as calling on a supportive Rails community. Whether they provided direct solutions to my programming woes, or simply planted a seed on how to solve a problem, I kept coding. Many months later, and after several more doubtful moments, Lodger was born.

 Property overview of my app, Lodger.

If I can do it, so can you

I misspent a lot of time building Twitter and blogging applications (apparently, all Rails tutorials centre around Twitter and blogging). If I could rewind and impart some advice to myself, this is what I’d say.

There’s no magic formula

“I haven’t quite grasped Rails routing. I should tackle another tutorial.” 

Making excuses — or procrastination — is something we are all guilty of. I was waiting for a programming book that would magically deposit a grasp of the entire Ruby syntax in my head. I kept buying books thinking each one would be the one where it all clicked. I now have a bookshelf full of Ruby material, all of which I’ve barely read, and none of which got me any closer to launching my web app. Put simply, there’s no magic formula.

Break it down

Whatever it is you want to build, break it down into digestible chunks. Taking Pete’s method as an example, having an index card represent an individual feature helped me tremendously. Tackle one at a time. Even if each feature takes you a month to build, and you have eight features to launch with, after eight months you’ll have your MVP. Remember, if you do nothing each day, it adds up to nothing.

Have a tangible product to build

I have a wonderful habit of writing down personal notes, usually to express my feelings at the time or to log an idea, only to uncover them months or years down the line, long after I forgot I had written them. I made a timely discovery while writing this article, discovering this gem while flicking through a battered Moleskine:


	“I don’t seem to be making good progress with learning Rails, but development still excites me. I should maybe stop doing tutorials and work towards building a specific app.”


Having a real product to work on, like I did with Lodger, means you have something tangible to apply the techniques you are learning. I found this prevented me from flitting aimlessly between tutorials and books, which is an easy area to accidentally remain in.

Team up

If possible, team up with a designer and create something together. Designers are great at presenting features in a way you’d never have considered. You will learn a lot from making their designs come to life.

Your homework for the holiday

Despite having a web app under my belt, I am not a programmer. I tinker with code, piecing enough bits of it together to make something functional. And that’s OK! I’m not excusing sloppiness, but if we aimed for perfection every time, we’d never execute any of our ideas.

As the holidays approach and you’ve exhausted yet another viewing of The Muppet Christmas Carol (or is that just my guilty pleasure at Christmas?), you may have time on your hands. Time to explore an idea you’ve been sitting on, but — plagued with procrastination and doubt — have yet to bring to life. This holiday, I am here to say to you what Pete said to me.

You should build this.

You don’t need to be the next Mark Zuckerberg or Larry Page. You just have to learn enough to get it done.

PS: I lied about the eggnogg, but try capturing somebody’s attention when you tell them you sell property insurance!",2013,Ashley Baxter,ashleybaxter,2013-12-06T00:00:00+00:00,https://24ways.org/2013/levelling-up/,business
21,Keeping Parts of Your Codebase Private on GitHub,"Open source is brilliant, there’s no denying that, and GitHub has been  instrumental in open source’s recent success. I’m a keen open-sourcerer myself, and I have a number of projects on GitHub. However, as great as sharing code is, we often want to keep some projects to ourselves. To this end, GitHub created private repositories which act like any other Git repository, only, well, private!

A slightly less common issue, and one I’ve come up against myself, is the desire to only keep certain parts of a codebase private. A great example would be my site, CSS Wizardry; I want the code to be open source so that people can poke through and learn from it, but I want to keep any draft blog posts private until they are ready to go live. Thankfully, there is a very simple solution to this particular problem: using multiple remotes.

Before we begin, it’s worth noting that you can actually build  a GitHub Pages site from a private repo. You can keep the entire source private, but still have GitHub build and display a full Pages/Jekyll site. I do this with csswizardry.net. This post will deal with the more specific problem of keeping only certain parts of the codebase (branches) private, and expose parts of it as either an open source project, or a built GitHub Pages site.

N.B. This post requires some basic Git knowledge.

Adding your public remote

Let’s assume you’re starting from scratch and you currently have no repos set up for your project. (If you do already have your public repo set up, skip to the “Adding your private remote” section.)

So, we have a clean slate: nothing has been set up yet, we’re doing all of that now. On GitHub, create two repositories. For the sake of this article we shall call them site.com and private.site.com. Make the site.com repo public, and the private.site.com repo private (you will need a paid GitHub account).

On your machine, create the site.com directory, in which your project will live. Do your initial work in there, commit some stuff — whatever you need to do. Now we need to link this local Git repo on your machine with the public repo (remote) on GitHub. We should all be used to this:

$ git remote add origin git@github.com:[user]/site.com.git

Here we are simply telling Git to add a remote called origin which lives at git@github.com:[user]/site.com.git. Simple stuff. Now we need to push our current branch (which will be master, unless you’ve explicitly changed it) to that remote:

$ git push -u origin master

Here we are telling Git to push our master branch to a corresponding master branch on the remote called origin, which we just added. The -u sets upstream tracking, which basically tells Git to always shuttle code on this branch between the local master branch and the master branch on the origin remote. Without upstream tracking, you would have to tell Git where to push code to (and pull it from) every time you ran the push or pull commands. This sets up a permanent bond, if you like.

This is really simple stuff, stuff that you will probably have done a hundred times before as a Git user. Now to set up our private remote.

Adding your private remote

We’ve set up our public, open source repository on GitHub, and linked that to the repository on our machine. All of this code will be publicly viewable on GitHub.com. (Remember, GitHub is just a host of regular Git repositories, which also puts a nice GUI around it all.) We want to add the ability to keep certain parts of the codebase private. What we do now is add another remote repository to the same local repository. We have two repos on GitHub (site.com and private.site.com), but only one repository (and, therefore, one directory) on our machine. Two GitHub repos, and one local one.

In your local repo, check out a new branch. For the sake of this article we shall call the branch dev. This branch might contain work in progress, or draft blog posts, or anything you don’t want to be made publicly viewable on GitHub.com. The contents of this branch will, in a moment, live in our private repository.

$ git checkout -b dev

We have now made a new branch called dev off the branch we were on last (master, unless you renamed it).

Now we need to add our private remote (private.site.com) so that, in a second, we can send this branch to that remote:

$ git remote add private git@github.com:[user]/private.site.com.git

Like before, we are just telling Git to add a new remote to this repo, only this time we’ve called it private and it lives at git@github.com:[user]/private.site.com.git. We now have one local repo on our machine which has two remote repositories associated with it.

Now we need to tell our dev branch to push to our private remote:

$ git push -u private dev

Here, as before, we are pushing some code to a repo. We are saying that we want to push the dev branch to the private remote, and, once again, we’ve set up upstream tracking. This means that, by default, the dev branch will only push and pull to and from the private remote (unless you ever explicitly state otherwise).

Now you have two branches (master and dev respectively) that push to two remotes (origin and private respectively) which are public and private respectively.

Any work we do on the master branch will push and pull to and from our publicly viewable remote, and any code on the dev branch will push and pull from our private, hidden remote.

Adding more branches

So far we’ve only looked at two branches pushing to two remotes, but this workflow can grow as much or as little as you’d like. Of course, you’d never do all your work in only two branches, so you might want to push any number of them to either your public or private remotes. Let’s imagine we want to create a branch to try something out real quickly:

$ git checkout -b test

Now, when we come to push this branch, we can choose which remote we send it to:

$ git push -u private test

This pushes the new test branch to our private remote (again, setting the persistent tracking with -u).

You can have as many or as few remotes or branches as you like.

Combining the two

Let’s say you’ve been working on a new feature in private for a few days, and you’ve kept that on the private remote. You’ve now finalised the addition and want to move it into your public repo. This is just a simple merge. Check out your master branch:

$ git checkout master

Then merge in the branch that contained the feature:

$ git merge dev

Now master contains the commits that were made on dev and, once you’ve pushed master to its remote, those commits will be viewable publicly on GitHub:

$ git push

Note that we can just run $ git push on the master branch as we’d previously set up our upstream tracking (-u).

Multiple machines

So far this has covered working on just one machine; we had two GitHub remotes and one local repository. Let’s say you’ve got yourself a new Mac (yay!) and you want to clone an existing project:

$ git clone git@github.com:[user]/site.com.git

This will not clone any information about the remotes you had set up on the previous machine. Here you have a fresh clone of the public project and you will need to add the private remote to it again, as above.

Done!

If you’d like to see me blitz through all that in one go, check the showterm recording.

The beauty of this is that we can still share our code, but we don’t have to develop quite so openly all of the time. Building a framework with a killer new feature? Keep it in a private branch until it’s ready for merge. Have a blog post in a Jekyll site that you’re not ready to make live? Keep it in a private drafts branch. Working on a new feature for your personal site? Tuck it away until it’s finished. Need a staging area for a Pages-powered site? Make a staging remote with its own custom domain.

All this boils down to, really, is the fact that you can bring multiple remotes together into one local codebase on your machine. What you do with them is entirely up to you!",2013,Harry Roberts,harryroberts,2013-12-09T00:00:00+00:00,https://24ways.org/2013/keeping-parts-of-your-codebase-private-on-github/,code
11,JavaScript: Taking Off the Training Wheels,"JavaScript is the third pillar of front-end web development. Of those pillars, it is both the most powerful and the most complex, so it’s understandable that when 24 ways asked, “What one thing do you wish you had more time to learn about?”, a number of you answered “JavaScript!”

This article aims to help you feel happy writing JavaScript, and maybe even without libraries like jQuery. I can’t comprehensively explain JavaScript itself without writing a book, but I hope this serves as a springboard from which you can jump to other great resources.

Why learn JavaScript?

So what’s in it for you? Why take the next step and learn the fundamentals?

Confidence with jQuery

If nothing else, learning JavaScript will improve your jQuery code; you’ll be comfortable writing jQuery from scratch and feel happy bending others’ code to your own purposes. Writing efficient, fast and bug-free jQuery is also made much easier when you have a good appreciation of JavaScript, because you can look at what jQuery is really doing. Understanding how JavaScript works lets you write better jQuery because you know what it’s doing behind the scenes. When you need to leave the beaten track, you can do so with confidence.

In fact, you could say that jQuery’s ultimate goal is not to exist: it was invented at a time when web APIs were very inconsistent and hard to work with. That’s slowly changing as new APIs are introduced, and hopefully there will come a time when jQuery isn’t needed.

An example of one such change is the introduction of the very useful document.querySelectorAll. Like jQuery, it converts a CSS selector into a list of matching elements. Here’s a comparison of some jQuery code and the equivalent without.

$('.counter').each(function (index) {
  $(this).text(index + 1);
});

var counters = document.querySelectorAll('.counter');
[].slice.call(counters).forEach(function (elem, index) {
  elem.textContent = index + 1;
});

Solving problems no one else has!

When you have to go to the internet to solve a problem, you’re forever stuck reusing code other people wrote to solve a slightly different problem to your own. Learning JavaScript will allow you to solve problems in your own way, and begin to do things nobody else ever has.

Node.js

Node.js is a non-browser environment for running JavaScript, and it can do just about anything! But if that sounds daunting, don’t worry: the Node community is thriving, very friendly and willing to help.

I think Node is incredibly exciting. It enables you, with one language, to build complete websites with complex and feature-filled front- and back-ends. Projects that let users log in or need a database are within your grasp, and Node has a great ecosystem of library authors to help you build incredible things. Exciting!

Here’s an example web server written with Node. http is a module that allows you to create servers and, like jQuery’s $.ajax, make requests. It’s a small amount of code to do something complex and, while working with Node is different from writing front-end code, it’s certainly not out of your reach.

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello World');
}).listen(1337);
console.log('Server running at http://localhost:1337/');

Grunt and other website tools

Node has brought in something of a renaissance in tools that run in the command line, like Yeoman and Grunt. Both of these rely heavily on Node, and I’ll talk a little bit about Grunt here.

Grunt is a task runner, and many people use it for compiling Sass or compressing their site’s JavaScript and images. It’s pretty cool. You configure Grunt via the gruntfile.js, so JavaScript skills will come in handy, and since Grunt supports plug-ins built with JavaScript, knowing it unlocks the bucketloads of power Grunt has to offer.

Ways to improve your skills

So you know you want to learn JavaScript, but what are some good ways to learn and improve? I think the answer to that is different for different people, but here are some ideas.

Rebuild a jQuery app

Converting a jQuery project to non-jQuery code is a great way to explore how you modify elements on the page and make requests to the server for data. My advice is to focus on making it work in one modern browser initially, and then go cross-browser if you’re feeling adventurous. There are many resources for directly comparing jQuery and non-jQuery code, like Jeffrey Way’s jQuery to JavaScript article.

Find a mentor

If you think you’d work better on a one-to-one basis then finding yourself a mentor could be a brilliant way to learn. The JavaScript community is very friendly and many people will be more than happy to give you their time. I’d look out for someone who’s active and friendly on Twitter, and does the kind of work you’d like to do. Introduce yourself over Twitter or send them an email. I wouldn’t expect a full tutoring course (although that is another option!) but they’ll be very glad to answer a question and any follow-ups every now and then.

Go to a workshop

Many conferences and local meet-ups run workshops, hosted by experts in a particular field. See if there’s one in your area. Workshops are great because you can ask direct questions, and you’re in an environment where others are learning just like you are — no need to learn alone!

Set yourself challenges

This is one way I like to learn new things. I have a new thing that I’m not very good at, so I pick something that I think is just out of my reach and I try to build it. It’s learning by doing and, even if you fail, it can be enormously valuable.

Where to start?

If you’ve decided learning JavaScript is an important step for you, your next question may well be where to go from here.

I’ve collected some links to resources I know of or use, with some discussion about why you might want to check a particular site out. I hope this serves as a springboard for you to go out and learn as much as you want.

Beginner

If you’re just getting started with JavaScript, I’d recommend heading to one of these places. They cover the basics and, in some cases, a little more advanced stuff. They’re all reputable sources (although, I’ve included something I wrote — you can decide about that one!) and will not lead you astray.


	jQuery’s JavaScript 101 is a great first resource for JavaScript that will give you everything you need to work with jQuery like a pro.
	Codecademy’s JavaScript Track is a small but useful JavaScript course. If you like learning interactively, this could be one for you.
	HTMLDog’s JavaScript Tutorials take you right through from the basics of code to a brief introduction to newer technology like Node and Angular. [Disclaimer: I wrote this stuff, so it comes with a hazard warning!]
	The tuts+ jQuery to JavaScript mentioned earlier is great for seeing how jQuery code looks when converted to pure JavaScript.


Getting in-depth

For more comprehensive documentation and help I’d recommend adding these places to your list of go-tos.


	MDN: the Mozilla Developer Network is the first place I go for many JavaScript questions. I mostly find myself there via a search, but it’s a great place to just go and browse.
	Axel Rauschmayer’s 2ality is a stunning collection of articles that will take you deep into JavaScript. It’s certainly worth looking at.
	Addy Osmani’s JavaScript Design Patterns is a comprehensive collection of patterns for writing high quality JavaScript, particularly as you (I hope) start to write bigger and more complex applications.


And finally…

I think the key to learning anything is curiosity and perseverance. If you have a question, go out and search for the answer, even if you have no idea where to start. Keep going and going and eventually you’ll get there. I bet you’ll learn a whole lot along the way. Good luck!

9,How to Write a Book,"Were you recently inspired to write a book after reading Owen Gregory’s compendium of author insights? Maybe so inspired to strike out on your own and self-publish? 

Based on personal experience, writing a book is hard. It requires a great deal of research, experience, and patience. To be able to consolidate your thoughts and what you’ve learned into a sensible and readable tome is an admirable feat. To decide to self-publish and take on yourself all of the design, printing, distribution, and so much more is tantamount to insanity. Again, based on personal experience.

So, why might you want to self-publish?

If you’ve spent many a late night doing cross-browser testing just to know that your site works flawlessly in twenty-four different browsers — including Mosaic, of course — then maybe you’ll understand the fun that comes from doing it all.

Working with a publisher, you’re left to focus on one core thing: writing. That’s a good thing. A good publisher has the right resources to help you get your idea polished and the distribution network to get your book on store shelves around the world. It’s a very proud moment to be able to walk into a book store and see your book sitting there on the shelf.

Self-publishing can also be a wonderful process as you get to own it from beginning to end. Every decision is yours and if you’re a control freak like me, this can be a very rewarding experience. 

While there are many aspects to self-publishing, I’m going to speak to just one of them: creating an ebook.

Formats 

In creating an ebook, you first need to decide what formats you wish to support. There are three main formats, each with their own pros and cons:


	PDF
	EPUB
	MOBI


PDFs are supported on almost every device (Windows, Mac, Kindle, iPad, Android, etc.) and can even be a stepping stone to creating a print version of your book. PDFs allow for full typographic and design control, but at the cost of needing to fit things into a predefined page layout. Is it US Letter or A4? Or is it a format that isn’t easily printed by readers on their home printers?

EPUB is a more fluid format that is supported by the Apple iPad, iPhone, and now on the desktop with OS X Mavericks. It’s also supported by Google Play for Android devices. While EPUB is supported on other devices, you’re likely to choose EPUB because you’re targeting your book at the Apple audience. The EPUB format is HTML-based with support for some CSS and even video and interactive elements. You can create very rich and exciting experiences using the EPUB format that just aren’t possible with PDF or MOBI. However, if you decide to support multiple file formats, you’ll likely find — as I did — that a consistent experience between all formats is easier to build and maintain, and therefore the extra benefits of interactivity go out the window.

MOBI is a format originally developed for the Mobipocket Reader but more popularly supported by the Amazon Kindle. If you’re looking to attract the Kindle audience or publish to Amazon via the Kindle Direct Publishing platform then the HTML-based MOBI format is the format you’ll want to go with. 

Distribution will probably factor in heavily with what format you decide to go with. Many people I know who self-publish go with PDF only due to its ubiquity. 

If you want to garner a wider audience by distributing via Amazon or the iBookstore then you’ll need to think about supporting all three formats (as I did).

What tools should I use?

I spent a lot of time figuring out the right toolset and finally got something that suits me just right.

In the past, when working with a publisher, I was given a Microsoft Word template that was passed back and forth between myself, the editor, and tech reviewer. This template has been the bane of any book writer that I’ve spoken to. Not every publisher is like that, though. Some publishers, like O’Reilly, use DocBook, an XML-based format that can be converted into PDF, EPUB, and MOBI.

Publishers already have a style guide and whether it’s DocBook or a Word template, they have the tools already in place to easily convert your work into multiple formats.

Self-publishing means that you’ll likely have to do a lot of tweaking to get things looking and working the way you want them to. I tried DocBook and the open source export tools didn’t create HTML to my liking. Fixing even the most mundane things required fiddling with XSL transformations for hours on end. Not the way I like to spend my time. I can only imagine the hoops I would’ve had to go through to get a PDF to look half-decent.

Tools like Pages or Scrivener offer up the ability to publish to multiple formats, too, but none offered me the control over the output that I truly desired. Have a mentioned that I’m a control freak?

I ended up writing my book using a technology that I already knew quite well: HTML. By writing in HTML, I already had something that I could post on my website, use for the EPUB and use for the MOBI format. All without having to change a thing. (That’s right: the same HTML that is used on SMACSS.com is used in the EPUB and is used in the MOBI.)

What about PDF? I could open up the HTML in a web browser, choose Save as PDF and be done with it but let’s face it: the filename and date attached to every single page doesn’t exactly scream professional. Web browsers actually do a surprisingly poor job with supporting the CSS paged media spec.

I had resorted to copying and pasting the content into Pages and saving as PDF from there. It wasn’t elegant but it worked. However, any changes to my HTML source required redoing those changes in Pages, as well. 

Then I met my Prince Charming: Prince XML. It’s pricey but it works incredibly well. It takes HTML and CSS (that very format I’ve been using for all of my other file formats) and will generate a PDF via a command line interface. Prince supports CSS paged media including headers, footers, page counts, and alternating page styles. 

From one format, HTML, I can now easily publish to PDF, MOBI, and EPUB, and even my website. I use the PDF version to send to the printer along with cover art to be bound and ready to ship around the world. It’s amazing how versatile HTML (and CSS) is.

To learn more about writing books with HTML and CSS, I recommend reading Building Books with CSS3 over at A List Apart.

Creating an EPUB

Let’s take a step back. Prince gets us from HTML to PDF but how do we make an EPUB out of the HTML? 

An EPUB file is essentially a ZIP file with a renamed extension. There are some core files that you need to start with:

Root
   META-INF
      container.xml
   mimetype
   content.opf
   toc.ncx

After that, you can start adding your content to the project. Be sure to update the toc.ncx (Table of Contents) and content.opf (the ebook manifest) with any changes you make to your project.

You can learn more about the file formats with the EPUB Format Construction Guide.

Once all your files are in place, you’ll need to create the EPUB file by running two commands (on OS X, at least):

zip -X0 your-ebook.epub mimetype
zip -Xur9D your-ebook.epub *

The mimetype needs to be the first file inside the ZIP file and therefore gets added first. Then, the rest of the files are added. 

I’ve added a function to my .bash_profile to make this even easier:

function epub()
{
   zip -q0X $@ mimetype; zip -qXr9D $@ *
}

Then, within the folder from which I want to create an ebook, I just run epub your-ebook.epub from the Terminal command line and the EPUB file should be ready to go.

Creating the MOBI

We have our EPUB and we have our PDF. The last step is the MOBI file. For this, I call upon Calibre. Calibre can be used as a reader and as a library but I use it exclusively to export my EPUB files to MOBI. 

Calibre includes a command line utility to convert from EPUB to MOBI. (To install the command line tools, go to Preferences > Advanced > Miscellaneous and click Install Command Line Tools.)

ebook-convert your-ebook.epub your-ebook.mobi 

Spread the joy

Now that you have all of your different file formats, you need to get them into the hands of people who want to (ho-ho-hopefully) buy your book!

There are a number of marketplaces such as Amazon’s Kindle Direct Publishing, iBookstore, Google Play, and NOOK Press.

Some publishers, like PragProg and O’Reilly will also add self-published books to their roster if they feel it’s a good fit for their audience.

With any distribution, you’ll have to give up a percentage of your sales—from 30% to 70% of each sale, so consider your options wisely.

Of course, you can always open your own online store and reap as much of the revenue as possible, assuming you can get the traffic to your site. Handling your own distribution allows you to create a deeper one-on-one connection with your customers, something that is impossible with other distribution channels since you don’t get customer information through other services—even though you are giving them a huge chunk of your sales!

Go forth and prosper

There’s a lot of thought and time that goes into writing a book and just as much thought and time can go into creating, publishing, and marketing your book once you’re done. 

In the end, self-publishing can be a very rewarding process and well worth the time that goes into it.",2013,Jonathan Snook,jonathansnook,2013-12-19T00:00:00+00:00,https://24ways.org/2013/how-to-write-a-book/,content
10,Home Kanban for Domestic Bliss,"My wife is an architect. I’m a leader of big technical teams these days, but for many years after I was a dev I was a project/program manager. Our friends and family used to watch Grand Designs and think that we would make the ideal team — she could design, I could manage the project of building or converting whatever dream home we wanted.

Then we bought a house.

A Victorian terrace in the north-east of England that needed, well, a fair bit of work. The big decisions were actually pretty easy: yes, we should knock through a double doorway from the dining room to the lounge; yes, we should strip out everything from the utility room and redo it; yes, we should roll back the hideous carpet in the bedrooms upstairs and see if we could restore the original wood flooring.

Those could be managed like a project.

What couldn’t be was all the other stuff. Incremental improvements are harder to schedule, and in a house that’s over a hundred years old you never know what you’re going to find when you clear away some tiles, or pull up the carpets, or even just spring-clean the kitchen (“Erm, hon? The paint seems to be coming off. Actually, so does the plaster…”). A bit like going in to fix bugs in code or upgrade a machine — sometimes you end up quite far down the rabbit hole.

And so, as we tried to fit in those improvements in our evenings and weekends, we found ourselves disagreeing. Arguing, even. We were both trying to do the right thing (make the house better) but since we were fitting it in where we could, we often didn’t get to talk and agree in detail what was needed (exactly how to make the house better). And it’s really frustrating when you stay up late doing something, just to find that your other half didn’t mean that they meant this instead, and so your effort was wasted.

Then I saw this tweet from my friend and colleague Jamie Arnold, who was using the same kanban board approach at home as we had instituted at the UK Government Digital Service to manage our portfolio.

Mrs Arnold embraces Kanban wall at home. Disagreements about work in progress and priority significantly reduced.. ;) pic.twitter.com/407brMCH— Jamie Arnold (@itsallgonewrong) October 27, 2012

And despite Jamie’s questionable taste in fancy dress outfits (look closely at that board), he is a proper genius when it comes to processes and particularly agile ones. So I followed his example and instituted a home kanban board.

What is this kanban of which you speak?

Kanban boards are an artefact from lean manufacturing — basically a visualisation of a production process. They are used to show you where your bottlenecks are, or where one part of the process is producing components faster than another part of the process can cope. Identifying the bottlenecks leads you to set work in progress (WIP) limits, so that you get an overall more efficient system.

Increasingly kanban is used as an agile software development approach, too, especially where support work (like fixing bugs) needs to be balanced with incremental enhancement (like adding new features).

I’m a big advocate of kanban when you have a system that needs to be maintained and improved by the same team at the same time. Rather than the sprint-based approach of scrum (where the next sprint’s stories or features to be delivered are agreed up front), kanban lets individuals deal with incidents or problems that need investigation and bug fixing when urgent and important. Then, when someone has capacity, they can just go to the board and pull down the next feature to develop or test.

So, how did we use it?

One of the key tenets of kanban is that you visualise your workflow, so we put together a whiteboard with columns: Icebox; To Do Next; In Process; Done; and also a section called Blocked. Then, for each thing that needed to happen in the house, we put it on a Post-it note and initially chucked them all in the Icebox — a collection with no priority assigned yet.

Each week we looked at the Icebox and pulled out a set of things that we felt should be done next. This was pulled into the To Do Next column, and then each time either of us had some time, we could just pull a new thing over into the In Process column. We agreed to review at the end of each week and move things to Done together, and to talk about whether this kanban approach was working for us or not.

We quickly learned for ourselves why kanban has WIP limits as a key tenet — it’s tempting to pull everything into the To Do Next column, but that’s unrealistic. And trying to do more than one or two things each at a given time isn’t terribly productive owing to the cost of task switching. So we tend to limit our To Do Next to about seven items, and our In Process to about four (a max of two each, basically).

We use the Blocked column when something can’t be completed — perhaps we can’t fix something because we discovered we don’t have the required tools or supplies, or if we’re waiting for a call back from a plumber. But it’s nice to put it to one side, knowing that it won’t be forgotten.

What helped the most?

It wasn’t so much the visualisation that helped us to see what we needed to do, but the conversation that happened when we were agreeing priorities, moving them to In Process and then on to Done made the biggest difference. Getting clear on the order of importance really is invaluable — as is getting clear on what Done really means!

The Blocked column is also great, as it helps us keep track of things we need to do outside the house to make sure we can make progress. We also found it really helpful to examine the process itself and figure out whether it was working for us. For instance, one thing we realised is it’s worth tracking some regular tasks that need time invested in them (like taking recycling that isn’t picked up to the recycling centre) and these used to cycle around and around. So they were moved to Done as part of our weekly review, but then immediately put back in the Icebox to float back to the top again at a relevant time.

But the best thing of all? That moment where we get to mark something as done! It’s immensely satisfying to review at the end of the week and have a physical marker of the progress you’ve made.

All in all, a home kanban board turned out to be a very effective way to pull tasks through stages rather than always trying to plan them out in advance, and definitely made collaboration on our home tasks significantly smoother.

18,Grunt for People Who Think Things Like Grunt are Weird and Hard,"Front-end developers are often told to do certain things:


	Work in as small chunks of CSS and JavaScript as makes sense to you, then concatenate them together for the production website.
	Compress your CSS and minify your JavaScript to make their file sizes as small as possible for your production website.
	Optimize your images to reduce their file size without affecting quality.
	Use Sass for CSS authoring because of all the useful abstraction it allows.


That’s not a comprehensive list of course, but those are the kind of things we need to do. You might call them tasks.

I bet you’ve heard of Grunt. Well, Grunt is a task runner. Grunt can do all of those things for you. Once you’ve got it set up, which isn’t particularly difficult, those things can happen automatically without you having to think about them again.

But let’s face it: Grunt is one of those fancy newfangled things that all the cool kids seem to be using but at first glance feels strange and intimidating. I hear you. This article is for you.

Let’s nip some misconceptions in the bud right away

Perhaps you’ve heard of Grunt, but haven’t done anything with it. I’m sure that applies to many of you. Maybe one of the following hang-ups applies to you.

I don’t need the things Grunt does

You probably do, actually. Check out that list up top. Those things aren’t nice-to-haves. They are pretty vital parts of website development these days. If you already do all of them, that’s awesome. Perhaps you use a variety of different tools to accomplish them. Grunt can help bring them under one roof, so to speak. If you don’t already do all of them, you probably should and Grunt can help. Then, once you are doing those, you can keep using Grunt to do more for you, which will basically make you better at doing your job.

Grunt runs on Node.js — I don’t know Node

You don’t have to know Node. Just like you don’t have to know Ruby to use Sass. Or PHP to use WordPress. Or C++ to use Microsoft Word.

I have other ways to do the things Grunt could do for me

Are they all organized in one place, configured to run automatically when needed, and shared among every single person working on that project? Unlikely, I’d venture.

Grunt is a command line tool — I’m just a designer

I’m a designer too. I prefer native apps with graphical interfaces when I can get them. But I don’t think that’s going to happen with Grunt1.

The extent to which you need to use the command line is:


	Navigate to your project’s directory.
	Type grunt and press Return.


After set-up, that is, which again isn’t particularly difficult.

OK. Let’s get Grunt installed

Node is indeed a prerequisite for Grunt. If you don’t have Node installed, don’t worry, it’s very easy. You literally download an installer and run it. Click the big Install button on the Node website.

You install Grunt on a per-project basis. Go to your project’s folder. It needs a file there named package.json at the root level. You can just create one and put it there.

 package.json at root

The contents of that file should be this:

{
  ""name"": ""example-project"",
  ""version"": ""0.1.0"",
  ""devDependencies"": {
    ""grunt"": ""~0.4.1""
  }
}

Feel free to change the name of the project and the version, but the devDependencies thing needs to be in there just like that.

This is how Node does dependencies. Node has a package manager called NPM (Node packaged modules) for managing Node dependencies (like a gem for Ruby if you’re familiar with that). You could even think of it a bit like a plug-in for WordPress.

Once that package.json file is in place, go to the terminal and navigate to your folder. Terminal rubes like me do it like this:

 Terminal rube changing directories

Then run the command:

npm install

After you’ve run that command, a new folder called node_modules will show up in your project.

 Example of node_modules folder

The other files you see there, README.md and LICENSE are there because I’m going to put this project on GitHub and that’s just standard fare there.

The last installation step is to install the Grunt CLI (command line interface). That’s what makes the grunt command in the terminal work. Without it, typing grunt will net you a “Command Not Found”-style error. It is a separate installation for efficiency reasons. Otherwise, if you had ten projects you’d have ten copies of Grunt CLI.

This is a one-liner again. Just run this command in the terminal:

npm install -g grunt-cli

You should close and reopen the terminal as well. That’s a generic good practice to make sure things are working right. Kinda like restarting your computer after you install a new application was in the olden days.

Let’s make Grunt concatenate some files

Perhaps in our project there are three separate JavaScript files:


	jquery.js – The library we are using.
	carousel.js – A jQuery plug-in we are using.
	global.js – Our authored JavaScript file where we configure and call the plug-in.


In production, we would concatenate all those files together for performance reasons (one request is better than three). We need to tell Grunt to do this for us.

But wait. Grunt actually doesn’t do anything all by itself. Remember Grunt is a task runner. The tasks themselves we will need to add. We actually haven’t set up Grunt to do anything yet, so let’s do that.

The official Grunt plug-in for concatenating files is grunt-contrib-concat. You can read about it on GitHub if you want, but all you have to do to use it on your project is to run this command from the terminal (it will henceforth go without saying that you need to run the given commands from your project’s root folder):

npm install grunt-contrib-concat --save-dev

A neat thing about doing it this way: your package.json file will automatically be updated to include this new dependency. Open it up and check it out. You’ll see a new line:

""grunt-contrib-concat"": ""~0.3.0""

Now we’re ready to use it. To use it we need to start configuring Grunt and telling it what to do.

You tell Grunt what to do via a configuration file named Gruntfile.js2

Just like our package.json file, our Gruntfile.js has a very special format that must be just right. I wouldn’t worry about what every word of this means. Just check out the format:

module.exports = function(grunt) {

    // 1. All configuration goes here 
    grunt.initConfig({
        pkg: grunt.file.readJSON('package.json'),

        concat: {
            // 2. Configuration for concatinating files goes here.
        }

    });

    // 3. Where we tell Grunt we plan to use this plug-in.
    grunt.loadNpmTasks('grunt-contrib-concat');

    // 4. Where we tell Grunt what to do when we type ""grunt"" into the terminal.
    grunt.registerTask('default', ['concat']);

};

Now we need to create that configuration. The documentation can be overwhelming. Let’s focus just on the very simple usage example.

Remember, we have three JavaScript files we’re trying to concatenate. We’ll list file paths to them under src in an array of file paths (as quoted strings) and then we’ll list a destination file as dest. The destination file doesn’t have to exist yet. It will be created when this task runs and squishes all the files together.

Both our jquery.js and carousel.js files are libraries. We most likely won’t be touching them. So, for organization, we’ll keep them in a /js/libs/ folder. Our global.js file is where we write our own code, so that will be right in the /js/ folder. Now let’s tell Grunt to find all those files and squish them together into a single file named production.js, named that way to indicate it is for use on our real live website.

concat: {   
    dist: {
        src: [
            'js/libs/*.js', // All JS in the libs folder
            'js/global.js'  // This specific file
        ],
        dest: 'js/build/production.js',
    }
}

Note: throughout this article there will be little chunks of configuration code like above. The intention is to focus in on the important bits, but it can be confusing at first to see how a particular chunk fits into the larger file. If you ever get confused and need more context, refer to the complete file.

With that concat configuration in place, head over to the terminal, run the command:

grunt

and watch it happen! production.js will be created and will be a perfect concatenation of our three files. This was a big aha! moment for me. Feel the power course through your veins. Let’s do more things!

Let’s make Grunt minify that JavaScript

We have so much prep work done now, adding new tasks for Grunt to run is relatively easy. We just need to:


	Find a Grunt plug-in to do what we want
	Learn the configuration style of that plug-in
	Write that configuration to work with our project


The official plug-in for minifying code is grunt-contrib-uglify. Just like we did last time, we just run an NPM command to install it:

npm install grunt-contrib-uglify --save-dev

Then we alter our Gruntfile.js to load the plug-in:

grunt.loadNpmTasks('grunt-contrib-uglify');

Then we configure it:

uglify: {
    build: {
        src: 'js/build/production.js',
        dest: 'js/build/production.min.js'
    }
}

Let’s update that default task to also run minification:

grunt.registerTask('default', ['concat', 'uglify']);

Super-similar to the concatenation set-up, right?

Run grunt at the terminal and you’ll get some deliciously minified JavaScript:

 Minified JavaScript

That production.min.js file is what we would load up for use in our index.html file.

Let’s make Grunt optimize our images

We’ve got this down pat now. Let’s just go through the motions. The official image minification plug-in for Grunt is grunt-contrib-imagemin. Install it:

npm install grunt-contrib-imagemin --save-dev

Register it in the Gruntfile.js:

grunt.loadNpmTasks('grunt-contrib-imagemin');

Configure it:

imagemin: {
    dynamic: {
        files: [{
            expand: true,
            cwd: 'images/',
            src: ['**/*.{png,jpg,gif}'],
            dest: 'images/build/'
        }]
    }
}

Make sure it runs:

grunt.registerTask('default', ['concat', 'uglify', 'imagemin']);

Run grunt and watch that gorgeous squishification happen:

 Squished images

Gotta love performance increases for nearly zero effort.

Let’s get a little bit smarter and automate

What we’ve done so far is awesome and incredibly useful. But there are a couple of things we can get smarter on and make things easier on ourselves, as well as Grunt:


	Run these tasks automatically when they should
	Run only the tasks needed at the time


For instance:


	Concatenate and minify JavaScript when JavaScript changes
	Optimize images when a new image is added or an existing one changes


We can do this by watching files. We can tell Grunt to keep an eye out for changes to specific places and, when changes happen in those places, run specific tasks. Watching happens through the official grunt-contrib-watch plugin.

I’ll let you install it. It is exactly the same process as the last few plug-ins we installed. We configure it by giving watch specific files (or folders, or both) to watch. By watch, I mean monitor for file changes, file deletions or file additions. Then we tell it what tasks we want to run when it detects a change.

We want to run our concatenation and minification when anything in the /js/ folder changes. When it does, we should run the JavaScript-related tasks. And when things happen elsewhere, we should not run the JavaScript-related tasks, because that would be irrelevant. So:

watch: {
    scripts: {
        files: ['js/*.js'],
        tasks: ['concat', 'uglify'],
        options: {
            spawn: false,
        },
    } 
}

Feels pretty comfortable at this point, hey? The only weird bit there is the spawn thing. And you know what? I don’t even really know what that does. From what I understand from the documentation it is the smart default. That’s real-world development. Just leave it alone if it’s working and if it’s not, learn more.

Note: Isn’t it frustrating when something that looks so easy in a tutorial doesn’t seem to work for you? If you can’t get Grunt to run after making a change, it’s very likely to be a syntax error in your Gruntfile.js. That might look like this in the terminal:

 Errors running Grunt

Usually Grunt is pretty good about letting you know what happened, so be sure to read the error message. In this case, a syntax error in the form of a missing comma foiled me. Adding the comma allowed it to run.

Let’s make Grunt do our preprocessing

The last thing on our list from the top of the article is using Sass — yet another task Grunt is well-suited to run for us. But wait? Isn’t Sass technically in Ruby? Indeed it is. There is a version of Sass that will run in Node and thus not add an additional dependency to our project, but it’s not quite up-to-snuff with the main Ruby project. So, we’ll use the official grunt-contrib-sass plug-in which just assumes you have Sass installed on your machine. If you don’t, follow the command line instructions.

What’s neat about Sass is that it can do concatenation and minification all by itself. So for our little project we can just have it compile our main global.scss file:

sass: {
    dist: {
        options: {
            style: 'compressed'
        },
        files: {
            'css/build/global.css': 'css/global.scss'
        }
    } 
}

We wouldn’t want to manually run this task. We already have the watch plug-in installed, so let’s use it! Within the watch configuration, we’ll add another subtask:

css: {
    files: ['css/*.scss'],
    tasks: ['sass'],
    options: {
        spawn: false,
    }
}

That’ll do it. Now, every time we change any of our Sass files, the CSS will automaticaly be updated.

Let’s take this one step further (it’s absolutely worth it) and add LiveReload. With LiveReload, you won’t have to go back to your browser and refresh the page. Page refreshes happen automatically and in the case of CSS, new styles are injected without a page refresh (handy for heavily state-based websites).

It’s very easy to set up, since the LiveReload ability is built into the watch plug-in. We just need to:


Install the browser plug-in
Add to the top of the watch configuration:
. watch: {
    options: {
        livereload: true,
    },
    scripts: {   
    /* etc */

Restart the browser and click the LiveReload icon to activate it.
Update some Sass and watch it change the page automatically.


 Live reloading browser

Yum.

Leveling up

As you might imagine, there is a lot of leveling up you can do with your build process. It surely could be a full time job in some organizations.

Some hardcore devops nerds might scoff at the simplistic setup we have going here. But I’d advise them to slow their roll. Even what we have done so far is tremendously valuable. And don’t forget this is all free and open source, which is amazing.

You might level up by adding more useful tasks:


	Running your CSS through Autoprefixer (A+ Would recommend) instead of a preprocessor add-ons.
	Writing and running JavaScript unit tests (example: Jasmine).
	Build your image sprites and SVG icons automatically (example: Grunticon).
	Start a server, so you can link to assets with proper file paths and use services that require a real URL like TypeKit and such, as well as remove the need for other tools that do this, like MAMP.
	Check for code problems with HTML-Inspector, CSS Lint, or JS Hint.
	Have new CSS be automatically injected into the browser when it ever changes.
	Help you commit or push to a version control repository like GitHub.
	Add version numbers to your assets (cache busting).
	Help you deploy to a staging or production environment (example: DPLOY).


You might level up by simply understanding more about Grunt itself:


	Read Grunt Boilerplate by Mark McDonnell.
	Read Grunt Tips and Tricks by Nicolas Bevacqua.
	Organize your Gruntfile.js by splitting it up into smaller files.
	Check out other people’s and projects’ Gruntfile.js.
	Learn more about Grunt by digging into its source and learning about its API.


Let’s share

I think some group sharing would be a nice way to wrap this up. If you are installing Grunt for the first time (or remember doing that), be especially mindful of little frustrating things you experience(d) but work(ed) through. Those are the things we should share in the comments here. That way we have this safe place and useful resource for working through those confusing moments without the embarrassment. We’re all in this thing together!

 

1 Maybe someday someone will make a beautiful Grunt app for your operating system of choice. But I’m not sure that day will come. The configuration of the plug-ins is the important part of using Grunt. Each plug-in is a bit different, depending on what it does. That means a uniquely considered UI for every single plug-in, which is a long shot.

Perhaps a decent middleground is this Grunt DevTools Chrome add-on.

2 Gruntfile.js is often referred to as Gruntfile in documentation and examples. Don’t literally name it Gruntfile — it won’t work.",2013,Chris Coyier,chriscoyier,2013-12-11T00:00:00+00:00,https://24ways.org/2013/grunt-is-not-weird-and-hard/,code
15,Git for Grown-ups,"You are a clever and talented person. You create beautiful designs, or perhaps you have architected a system that even my cat could use. Your peers adore you. Your clients love you. But, until now, you haven’t *&^#^! been able to make Git work. It makes you angry inside that you have to ask your co-worker, again, for that *&^#^! command to upload your work.

It’s not you. It’s Git. Promise.

Yes, this is an article about the popular version control system, Git. But unlike just about every other article written about Git, I’m not going to give you the top five commands that you need to memorize; and I’m not going to tell you all your problems would be solved if only you were using this GUI wrapper or that particular workflow. You see, I’ve come to a grand realization: when we teach Git, we’re doing it wrong.

Let me back up for a second and tell you a little bit about the field of adult education. (Bear with me, it gets good and will leave you feeling both empowered and righteous.) Andragogy, unlike pedagogy, is a learner-driven educational experience. There are six main tenets to adult education: 


	Adults prefer to know why they are learning something.
	The foundation of the learning activities should include experience.
	Adults prefer to be able to plan and evaluate their own instruction.
	Adults are more interested in learning things which directly impact their daily activities.
	Adults prefer learning to be oriented not towards content, but towards problems.
	Adults relate more to their own motivators than to external ones.


Nowhere in this list does it include “memorize the five most popular Git commands”. And yet this is how we teach version control: init, add, commit, branch, push. You’re an expert! Sound familiar? In the hierarchy of learning, memorizing commands is the lowest, or most basic, form of learning. At the peak of learning you are able to not just analyze and evaluate a problem space, but create your own understanding in relation to your existing body of knowledge.

“Fine,” I can hear you saying to yourself. “But I’m here to learn about version control.” Right you are! So how can we use this knowledge to master Git? First of all: I give you permission to use Git as a tool. A tool which you control and which you assign tasks to. A tool like a hammer, or a saw. Yes, your mastery of your tools will shape the kinds of interactions you have with your work, and your peers. But it’s yours to control. Git was written by kernel developers for kernel development. The web world has adopted Git, but it is not a tool designed for us and by us. It’s no Sass, y’know? Git wasn’t developed out of our frustration with managing CSS files in an increasingly complex ecosystem of components and atomic design. So, as you work through the next part of this article, give yourself a bit of a break. We’re in this together, and it’s going to be OK.

We’re going to do a little activity. We’re going to create your perfect Git cheatsheet.

I want you to start by writing down a list of all the people on your code team. This list may include:


	developers
	designers
	project managers
	clients


Next, I want you to write down a list of all the ways you interact with your team. Maybe you’re a solo developer and you do all the tasks. Maybe you only do a few things. But I want you to write down a list of all the tasks you’re actually responsible for. For example, my list looks like this:


	writing code
	reviewing code
	publishing tested code to your server(s)
	troubleshooting broken code


The next list will end up being a series of boxes in a diagram. But to start, I want you to write down a list of your tools and constraints. This list potentially has a lot of noun-like items and verb-like items:


	code hosting system (Bitbucket? GitHub? Unfuddle? self-hosted?)
	server ecosystem (dev/staging/live)
	automated testing systems or review gates
	automated build systems (that Jenkins dude people keep referring to)


Brilliant! Now you’ve got your actors and your actions, it’s time to shuffle them into a diagram. There are many popular workflow patterns. None are inherently right or wrong; rather, some are more or less appropriate for what you are trying to accomplish.

Centralized workflow

Everyone saves to a single place. This workflow may mean no version control, or a very rudimentary version control system which only ever has a single copy of the work available to the team at any point in time.

 

Branching workflow

Everyone works from a copy of the same place, merging their changes into the main copy as their work is completed. Think of the branches as a motorcycle sidecar: they’re along for the ride and probably cannot exist in isolation of the main project for long without serious danger coming to the either the driver or sidecar passenger. Branches are a fundamental concept in version control — they allow you to work on new features, bug fixes, and experimental changes within a single repository, but without forcing the changes onto others working from the same branch.

 

Forking workflow

Everyone works from their own, independent repository. A fork is an exact duplicate of a repository that a developer can make their own changes to. It can be kept up to date with additional changes made in other repositories, but it cannot force its changes onto another’s repository. A fork is a complete repository which can use its own workflow strategies. If developers wish to merge their work with the main project, they must make a request of some kind (submit a patch, or a pull request) which the project collaborators may choose to adopt or reject. This workflow is popular for open source projects as it enforces a review process.

 

Gitflow workflow

A specific workflow convention which includes five streams of parallel coding efforts: master, development, feature branches, release branches, and hot fixes. This workflow is often simplified down to a few elements by web teams, but may be used wholesale by software product teams. The original article describing this workflow was written by Vincent Driessen back in January 2010.

 

But these workflows aren’t about you yet, are they? So let’s make the connections.

From the list of people on your team you identified earlier, draw a little circle. Give each of these circles some eyes and a smile. Now I want you to draw arrows between each of these people in the direction that code (ideally) flows. Does your designer create responsive prototypes which are pushed to the developer? Draw an arrow to represent this.

Chances are high that you don’t just have people on your team, but you also have some kind of infrastructure. Hopefully you wrote about it earlier. For each of the servers and code repositories in your infrastructure, draw a square. Now, add to your diagram the relationships between the people and each of the machines in the infrastructure. Who can deploy code to the live server? How does it really get there? I bet it goes through some kind of code hosting system, such as GitHub. Draw in those arrows.

But wait!

The code that’s on your development machine isn’t the same as the live code. This is where we introduce the concept of a branch in version control. In Git, a repository contains all of the code (sort of). A branch is a fragment of the code that has been worked on in isolation to the other branches within a repository. Often branches will have elements in common. When we compare two (or more) branches, we are asking about the difference (or diff) between these two slivers. Often the master branch is used on production, and the development branch is used on our dev server. The difference between these two branches is the untested code that is not yet deployed.

On your diagram, see if you can colour-code according to the branch names at each of the locations within your infrastructure. You might find it useful to make a few different copies of the diagram to isolate each of the tasks you need to perform. For example: our team has a peer review process that each branch must go through before it is merged into the shared development branch.

Finally, we are ready to add the Git commands necessary to make sense of the arrows in our diagram. If we are bringing code to our own workstation we will issue one of the following commands: clone (the first time we bring code to our workstation) or pull. Remembering that a repository contains all branches, we will issue the command checkout to switch from one branch to another within our own workstation. If we want to share a particular branch with one of our team mates, we will push this branch back to the place we retrieved it from (the origin). Along each of the arrows in your diagram, write the name of the command you are are going to use when you perform that particular task.

 

From here, it’s up to you to be selfish. Before asking Git what command it would like you to use, sketch the diagram of what you want. Git is your tool, you are not Git’s tool. Draw the diagram. Communicate your tasks with your team as explicitly as you can. Insist on being a selfish adult learner — demand that others explain to you, in ways that are relevant to you, how to do the things you need to do today.",2013,Emma Jane Westby,emmajanewestby,2013-12-04T00:00:00+00:00,https://24ways.org/2013/git-for-grownups/,code
7,Get Started With GitHub Pages (Plus Bonus Jekyll),"After several failed attempts at getting set up with GitHub Pages, I vowed that if I ever figured out how to do it, I’d write it up. Fortunately, I did eventually figure it out, so here is my write-up.

Why I think GitHub Pages is cool

Normally when you host stuff on GitHub, you’re just storing your files there. If you push site files, what you’re storing is the code, and when you view a file, you’re viewing the code rather than the output. What GitHub Pages lets you do is store those files, and if they’re HTML files, you can view them like any other website, so there’s no need to host them separately yourself.

GitHub Pages accepts static HTML but can’t execute languages like PHP, or use a database in the way you’re probably used to, so you’ll need to output static HTML files. This is where templating tools such as Jekyll come in, which I’ll talk about later.

The main benefit of GitHub Pages is ease of collaboration. Changes you make in the repository are automatically synced, so if your site’s hosted on GitHub, it’s as up-to-date as your GitHub repository. This really appeals to me because when I just want to quickly get something set up, I don’t want to mess around with hosting; and when people submit a pull request, I want that change to be visible as soon as I merge it without having to set up web hooks.

Before you get started

If you’ve used GitHub before, already have an account and know the basics like how to set up a repository and clone it to your computer, you’re good to go. If not, I recommend getting familiar with that first. The GitHub site has extensive documentation on getting started, and if you’re not a fan of using the command line, the official GitHub apps for Mac and Windows are great.

I also found this tutorial about GitHub Pages by Thinkful really useful, and it contains details on how to turn an existing repository into a GitHub Pages site.

Although this involves a bit of using the command line, it’s minimal, and I’ll guide you through the basics.

Setting up GitHub Pages

For this demo we’re going to build a Christmas recipe site — nothing complex, just a place to store recipes so we can share them with people, and they can fork or suggest changes to ones they like. My GitHub username is maban, and the project I’ve set up is called christmas-recipes, so once I’ve set up GitHub Pages, the site can be found here: http://maban.github.io/christmas-recipes/

You can set up a custom domain, but by default, the URL for your GitHub Pages site is your-username.github.io/your-project-name.

Set up the repository

The first thing we’re going to do is create a new GitHub repository, in exactly the same way as normal, and clone it to the computer. Let’s give it the name christmas-recipes. There’s nothing in it at the moment, but that’s OK.



After setting up the repository on the GitHub website, I cloned it to my computer in my Sites folder using the GitHub app (you can clone it somewhere else, if you want), and now I have a local repository synced with the remote one on GitHub.

Navigate to the repository

Now let’s open up the command line and navigate to the local repository. The easiest way to do this in Terminal is by typing cd  and dragging and dropping the folder into the terminal window and pressing Return. You can refer to Chris Coyier’s GIF illustrating this very same thing, from last week’s 24 ways article “Grunt for People Who Think Things Like Grunt are Weird and Hard” (which is excellent).

So, for me, that’s…

cd /Users/Anna/Sites/christmas-recipes 

Create a special GitHub Pages branch

So far we haven’t done anything different from setting up a regular repository, but here’s where things change.

Now we’re in the right place, let’s create a gh-pages branch. This tells GitHub that this is a special branch, and to treat the contents of it differently.

Make sure you’re still in the christmas-recipes directory, and type this command to create the gh-pages branch:

git checkout --orphan gh-pages

That --orphan option might be new to you. An orphaned branch is an empty branch that’s disconnected from the branch it was created off, and it starts with no commits, making it a special standalone branch. checkout switches us from the branch we were on to that branch.

If all’s gone well, we’ll get a message saying Switched to a new branch ‘gh-pages’.

You may get an error message saying you don’t have admin privileges, in which case you’ll need to type sudo at the start of that command.

Make gh-pages your default branch (optional)

The gh-pages branch is separate to the master branch, but by default, the master branch is what will show up if we go to our repository’s URL on GitHub. To change this, go to the repository settings and select gh-pages as the default branch.



If, like me, you only want the one branch, you can delete the master branch by following Oli Studholme’s tutorial. It’s actually really easy to do, and means you only have to worry about keeping one branch up to date.

If you prefer to work from master but push updates to the gh-pages branch, Lea Verou has written up a quick tutorial on how to do this, and it basically involves working from the master branch, and using git rebase to bring one branch up to date with another.

At the moment, we’ve only got that branch on the local machine, and it’s empty, so to be able to see something at our special GitHub Pages URL, we’ll need to create a page and push it to the remote repository.

Make a page

Open up your favourite text editor, create a file called index.html in your christmas-recipes folder, and put some exciting text in it. Don’t worry about the markup: all we need is text because right now we’re just checking it works.



Now, let’s commit and push our changes. You can do that in the command line if you’re comfortable with that, or you can do it via the GitHub app. Don’t forget to add a useful commit message.



Now we’re ready to see our gorgeous new site! Go to your-username.github.io/your-project-name and, hopefully, you’ll see your first GitHub Pages site. If not, don’t panic, it can take up to ten minutes to publish, so you could make a quick cake in a cup while you wait.

After a short wait, our page should be live! Hopefully that wasn’t too traumatic. Now we know it works, we can add some proper markup and CSS and even some more pages.

If you’re feeling brave, how about we take it to the next level…

Setting up Jekyll

Since GitHub Pages can’t execute languages like PHP, we need to give it static HTML files. This is fine if there are only a few pages, but soon we’ll start to miss things like PHP includes for content that’s the same on every page, like headers and footers.

Jekyll helps set up templates and turn them into static HTML. It separates markup from content, and makes it a lot easier for people to edit pages collaboratively. With our recipe site, we want to make it really easy for people to fix typos or add notes, without having to understand PHP. Also, there’s the added benefit that static HTML pages load really fast.

Jekyll isn’t officially supported on Windows, but it is still possible to run it if you’re prepared to get your hands dirty.

Install Jekyll

Back in Terminal, we’re going to install Jekyll…

gem install jekyll

…and wait for the script to run. This might take a few moments. It might take so long that you get worried its broken, but resist the urge to start mashing your keyboard like I did.

Get Jekyll to run on the repository

Fingers crossed nothing has gone wrong so far. If something did go wrong, don’t give up! Check this helpful post by Andy Taylor – you probably just need to install something else first. 

Now we’re going to tell Jekyll to set up a new project in the repository, which is in my Sites folder (yours may be in a different place). Remember, we can drag the directory into the terminal window after the command.

jekyll new /Users/Anna/Sites/christmas-recipes

If everything went as expected, we should get this error message: Conflict: /Users/Anna/Sites/christmas-recipes exists and is not empty.

But that’s OK. It’s just upset because we’ve got that index.html file and possibly also a README.md in there that we made earlier. So move those onto your desktop for the moment and run the command again.

jekyll new /Users/Anna/Sites/christmas-recipes

It should say that the site has installed.

Check you’re in the repository, and if you’re not, navigate to it by typing cd , drag the christmas-recipes directory into terminal…

jekyll cd /Users/Anna/Sites/christmas-recipes

…and type this command to tell Jekyll to run:

jekyll serve --watch

By adding --watch at the end, we’re forcing Jekyll to rebuild the site every time we hit Save, so we don’t have to keep telling it to update every time we want to view the changes. We’ll need to run this every time we start work on the project, otherwise changes won’t be applied. For now, wait while it does its thing. 

Update the config file

When it’s finished, we’ll see the text press ctrl-c to stop. Don’t do that, though. Instead, open up the directory. You’ll notice some new files and folders in there. There’s one called _site, and that’s where all the site files are saved when they’re turned into static HTML. Don’t touch the files in here — they’re the generated files and will get overwritten every time we make changes to pages and layouts.

There’s a file in our directory called _config.yml. This has some settings we can change, one of them being what our base URL is. GitHub Pages will assume the base URL is above the project repository, so changing the settings here will help further down the line when setting up navigation links.

Replace the contents of the _config.yml file with this:

name: Christmas Recipes
markdown: redcarpet
pygments: true
baseurl: /christmas-recipes

Set up your files

Overwrite the index.html file in the root with the one we made earlier (you might want to pop the README.md back in there, too). 

Delete the files in the css folder — we’ll add our own later.

View the Jekyll site

Open up your favourite browser and type http://localhost:4000/christmas-recipes in the address bar.



Check it out, that’s your site! But it could do with a bit more love.

Set up the _includes files

It’s always useful to be able to pull in snippets of content onto pages, such as the header and footer, so they only need to be updated in one place. That’s what an _includes folder is for in Jekyll. Create a folder in the root called _includes, and within it add two files: head.html and foot.html. 

In head.html, paste the following:

<!DOCTYPE html>
<html>
    <head>
        <meta charset=""utf-8"">
        <title>{{ page.title }}</title>
        <link rel=""stylesheet"" href=""{{ site.baseurl }}/css/main.css"" >
    </head>
    <body>

and in foot.html:

</body>
</html>

Whenever we want to pull in something from the _includes folder, we can use {% include filename.html %} in the layout file — I’ll show you how to set that up in next step.

Making layouts

In our directory, there’s a folder called _layouts and this lets us create a reusable template for pages. Inside that is a default.html file. 

Delete everything in default.html and paste in this instead:

{% include head.html %}

    <h1>{{ page.title }}</h1>

    {{ content }}

{% include foot.html %}

That’s a very basic page with a header, footer, page title and some content. To apply this template to a page, go back into the index.html page and add this snippet to the very top of the file:

---
layout: default
title: Home
---

Now save the index.html file and hit Refresh in the browser. We should see a heading where {{ page.title }} was in the layout, which matches what comes after title: on the page itself (in this case, Home). So, if we wanted a subheading to appear on every page, we could add {{ page.subheading }} to where we want it to appear in our layout file, and a line that says subheading: This is a subheading in between the dashes at the top of the page itself.

Using Markdown for templates

Anything on a page that sits under the closing dashes is output where {{ content }} appears in the template file. At the moment, this is being output as HTML, but we can use Markdown instead, and Jekyll will convert that into HTML. For this recipe site, we want to make it as easy as possible for people to be able to collaborate, and also have the markup separate from the content, so let’s use Markdown instead of HTML for the recipes.

Telling a page to use Markdown instead of HTML is incredibly simple. All we need to do is change the filename from .html to .md, so let’s rename the index.html to index.md. Now we can use Markdown, and Jekyll will output that as HTML.

Create a new layout

We’re going to create a new layout called recipe which is going to be the template for any recipe page we create. Let’s keep it super simple.

In the _layouts folder, create a file called recipe.html and paste in this:

{% include head.html %}

	<main>

    	<h1>{{ page.title }}</h1>

    	{{ content }}

    	<p>Recipe by <a href=""{{ page.recipe-attribution-link }}"">{{ page.recipe-attribution }}</a>.</p>

	</main>

	{% include nav.html %}

{% include foot.html %}

That’s our template. The content that goes on the recipe layout includes a page title, the recipe content, a recipe attribution and a recipe attribution link.

Adding some recipe pages

Create a new file in the root of the christmas-recipes folder and call it gingerbread.md. Paste the following into it:

---
layout: recipe
title: Gingerbread
recipe-attribution: HungryJenny
recipe-attribution-link: http://www.opensourcefood.com/people/HungryJenny/recipes/soft-christmas-gingerbread-cookies
---
Makes about 15 small cookies.

## Ingredients

* 175g plain flour
* 90g brown sugar
* 50g unsalted butter, diced, at room temperature
* 2 tbsp golden syrup
* 1 egg, beaten
* 1 tsp ground ginger
* 1 tsp cinnamon
* 1 tsp bicarbonate of soda
* Icing sugar to dust

## Method

1. Sift the flour, ginger, cinnamon and bicarbonate of soda into a large mixing bowl.
2. Use your fingers to rub in the diced butter. Mix in the sugar.
3. Mix the egg with the syrup then pour into the flour mixture. Fold in well to form a dough.
4. Tip some flour onto the work surface and knead the dough until smooth.
5. Preheat the oven to 180°C.
6. Roll the dough out flat and use a shaped cutter to make as many cookies as you like.
7. Transfer the cookies to a tray and bake in the oven for 15 minutes. Lightly dust the cookies with icing sugar.

The content is in Markdown, and when we hit Save, it’ll be converted into HTML in the _site folder. Save the file, and go to http://localhost:4000/christmas-recipes/gingerbread.html in your favourite browser.

 

As you can see, the Markdown content has been converted into HTML, and the attribution text and link has been inserted in the right place.


Add some navigation

In your _includes folder, create a new file called nav.html. Here is some code that will generate your navigation:

<nav class=""nav-primary"" role=""navigation"" >
    <ul>
        {% for p in site.pages %}
        <li>
        	<a {% if p.url == page.url %}class=""active""{% endif %} href=""{{ site.baseurl }}{{ p.url }}"">{{ p.title }}</a>
        </li>
        {% endfor %}
    </ul>
</nav>

This is going to look for all pages and generate a list of them, and give the navigation item that is currently active a class of active so we can style it differently.

Now we need to include that navigation snippet in our layout. Paste {% include nav.html %} in default.html file, under {{ content }}.

Push the changes to GitHub Pages

Now we’ve got a couple of pages, it’s time to push our changes to GitHub. We can do this in exactly the same way as before. Check your special GitHub URL (your-username.github.io/your-project-name) and you should see your site up and running.

If you quit Terminal, don’t forget to run jekyll serve --watch from within the directory the next time you want to work on the files.

Next steps

Now we know the basics of creating Jekyll templates and publishing them as GitHub Pages, we can have some fun adding more pages and styling them up.

 
 
 Here’s one I made earlier


I’ve only been using Jekyll for a matter of weeks, mainly for prototyping. It’s really good as a content management system for blogs, and a lot of people host their Jekyll blogs on GitHub, such as Harry Roberts


	By hosting the code so openly it will make me take more pride in it and allow me to work on it much more easily; no excuses now!


Overall, the documentation for Jekyll feels a little sparse and geared more towards blogs than other sites, but as more people discover the benefits of it, I’m sure this will improve over time.

If you’re interested in poking about with some code, all the files from this tutorial are available on GitHub.",2013,Anna Debenham,annadebenham,2013-12-18T00:00:00+00:00,https://24ways.org/2013/get-started-with-github-pages/,
13,Data-driven Design with an Annual Survey,"Too often, we base designs on assumptions that don’t match customer perspectives. Why? Because the data we need to make informed decisions isn’t available.

Imagine starting off the year with a treasure trove of user data that can be filtered, sliced, and diced to inform new UI designs, help you discover where users struggle the most, and expose emerging trends in your customers’ needs that could lead to new features. Why, that would be useful indeed. And it’s easy to obtain by conducting an annual survey.

Annual surveys may seem as exciting as receiving socks and undies for Christmas, but they’re the gift that keeps on giving all year long (just like fresh socks and undies). I’m not ashamed to admit it: I love surveys! Each time my design research team runs a survey, we learn so much about customer motivations, interests, and behaviors. 

Surveys provide an aggregate snapshot of your users that can’t easily be obtained by other research methods, and they can be conducted quickly too. You can build a survey in a few hours, run a pilot test in a day, and have real results streaming in the following day. Speed is essential if design research is going to keep pace with a busy product release schedule. 

Surveys are also an invaluable springboard for customer interviews, which provide deep perspectives on user behavior. If you play your cards right as you construct your survey, you can capture a user ID and an email address for each respondent, making it easy to get in touch with customers whose feedback is particularly intriguing. No more recruiting customers for your research via Twitter or through a recruiting company charging a small fortune. You can filter survey responses and isolate the exact customers to talk with in moments, not months.

I love this connected process of sending targeted surveys, filtering the results, and then — with surgical precision — selecting just the right customers to interview. Not only is it fast and cheap, but it lets design researchers do quantitative and qualitative research in a coordinated way. Aggregate survey responses help you quantify the perspectives of different user segments, and interviews help you get into the heads of your customers.

An annual survey can give your team the data needed to make more informed designs in the new year. It all starts with a plan.

Planning your survey

Before you start jotting down questions to ask users, spend some time thinking about the work your team will be doing in the coming year. Are you planning new mobile apps or a responsive redesign? Then questions about devices used and behaviors around mobile devices might be in order. Rethinking your content strategy? Then you might want to ask a few questions about how your customers consume content.

You can’t predict all of the projects you’ll be working on in the coming year, but tuck a couple of sections in your survey about the projects you’re certain about. This will give you the research you need to start new projects with solid foundational data.

Google Drive is a great place to start collaboratively building survey questions with colleagues. Questions that seem crystal clear in your head get challenged, refined, or even expanded quickly when the entire team can chime in. 

As you craft your survey, try to consider how you’ll filter it once all of the data is compiled. Do you need to see responses by industry, by age of an account, by devices used, or by size of company? Adding the right filter questions can help you discover fascinating patterns in user segments. Filtering on responses to a few questions can surface insights like: customers in non-profit companies with more than 100 employees are 17% more likely to use an Android phone and are most attracted to features A, D, and F. A designer working on the landing page for a non-profit would love to have concrete information like this. Filter questions are key, so consider them carefully. But don’t go overboard — too many of them and you’ll start to hurt your survey response rate.

Multiple choice questions are the heart of most surveys because respondents can complete them quickly, which increases response rate, and researchers can analyze them without a lot of manual categorization. Open text field questions are valuable too, but be careful not to add too many to your survey. You’ll hate yourself after the survey’s done and you have to sort through and tag thousands of open responses so patterns become visible. Oy vey!

An open-ended question works well towards the end of the survey. At this point respondents have a lot of topics swirling around in their head and tend to say weird things that will pique your interest. This is where you’ll find the outliers who are using your product. They’ll be fascinating to interview, and on occasion will help you see your work in a brand new way.

Conclude your survey with a question asking permission to get in touch for a followup interview so you don’t pester people who want to be left alone. 

With your questions nailed down, it’s time to build out that survey and get it ready for sending!

Building your survey

There are dozens of apps you could use to build your survey, but SurveyMonkey is the one that I prefer. It lets you pass in variables for each respondent such as user ID and email address. Metadata about respondents is essential if you’re going to do any follow-up interviews with your customers in the coming year. SurveyMonkey also makes it easy to set up question logic, showing questions to customers only if they responded in a certain way to a prior question. This helps you avoid asking irrelevant questions to some respondents.

Determining survey recipients

Once you’ve chosen a survey tool and entered all of your questions, you need to gather a list of recipients. Your first instinct will be to send it to everyone. You might say, “I need maximum response and metric shit tons of data!” But this is rarely the best approach — broad distribution almost always leads to lower response rates, increased noise, and decreased signal in your data. Are there subsets of customers you could send to, like only those who are active, those who are paying, or have been with you for a certain length of time? Talk to the keepers of your customer database and see how they can segment it so you can be certain you’re talking to just the people who will have the most relevant responses for your needs. 

If you want to get super nerdy when finding the right customer sample to survey, use a [sample size calculator]. Sampling is a deep subject best explored in other articles. 

Crafting your survey email

After focusing your energies on writing and building your survey, the email asking your customers to respond seems almost trivial, but it will greatly influence your response rate. Take great care when writing your subject line and the body of the email. If you can pull it off, A/B testing subject lines can greatly improve the open rate of your email and click-through to your survey. My design research team has seen a ~10% increase in open and click rates when we A/B tested. We’ve found that personalizing subject lines and greetings with the recipients name (ie. “Hey, Aarron. How can we make our app work better for you?”) gave us the best response rates. Your mileage may vary.

The tone of your email is important — be friendly, honest, and to the point. Those that are passionate about your product will be happy to share their perspective. Writing a survey email that people will actually respond to ain’t easy — in fact, they’re almost always annoying. But Ben Chestnut found a non-annoying way to send a survey email and improve response rates.

The email sent for the 2013 MailChimp survey let customers know what we’d been up to in the previous year, and invited feedback on what we should work on in the coming year.

The link to your survey should be a clear call to action. A big button with a label like “Answer a few questions” generally does the trick. The URL linking to the survey will need to include some variables like user ID and email. It might look something like this if you’re using SurveyMonkey:

http://surveymonkey.com/s/somesurveyid/?uid=*|UID|*&email=*|email|*

As each email is sent, the proper data will be populated in the variables, passing it on to the survey app for inclusion in each response. This is the magic that will help you pinpoint customers to interview down the road, so take special care to test that all is working before sending to all recipients. How you construct the survey link will vary depending on what survey tool and email service provider you use, so don’t take my example as gospel. You’ll need to read the documentation for your survey and email apps to set things up properly.

Pilot before sending

By now, you’ve whipped yourself into a fever pitch over your brilliant survey and the data you hope to collect. Your finger is on the send button, poised for action, but there’s one very important thing to do before you send to the entire list of customers: send a pilot email. How do you know if your questions are clear, your form logic is sound, and you’re passing variables from the email to the survey properly? You won’t, unless you send to a small segment of your recipients first. 

The data collected in your pilot will make plain where your survey needs refinement. This data won’t be used in your final analysis, as you’re probably going to make a few changes to your questions.

Send the pilot survey to enough people that you can really stress test the clarity of the questions and data you’re gathering, while considering how much data can you comfortably throw out. If you’re sending your final survey to a few thousand people, you might find a couple of hundred recipients for your pilot will give you enough insight into what to improve while leaving the vast majority of the recipients for your final survey.

After you’ve sent your pilot, made your survey adjustments, and ensured the variables are being passed from your email into the survey app, you’re ready to send to the remainder of your customers. This is your moment of glory!

Analyzing your results

After a couple of weeks you can probably safely close the survey so no other responses come in as you transition from data gathering to data analysis. Any survey app worth its salt will chart responses to your multiple choice questions. Reviewing these charts is a great place to start your analysis. Is there anything particularly interesting that stands out? Jot down some of your observations. I like to print screenshots of the charts for each question, highlighting areas of interest. These prints become a particularly handy reference point for the next step in your analysis. 

Printing results from a survey makes comparing different customers easy.

Viewing aggregate data about all responses is interesting, but the deltas between different types of customers are where the real revelations happen. Remember those filter questions you added to your survey? They’re the tool that’ll help you compare customer segments.

Most survey apps will let you filter the data based on response to a question. If the one you’re using doesn’t, you can always export your data and create pivot tables in Excel. Try filtering your data based on one of your filter questions, such as industry, company size, or devices used. Now compare those printed screenshots of baseline responses to the filtered data. Chances are you’ll see some significant differences in how each group responded to your questions, giving you clues about the variance in interests and motivations in customer segments and a leg up as you work on future design projects. 

Open-ended responses are equally interesting, but much more time-consuming to analyze. Yes, you need to read through thousands of responses, some of which are constructive and some of which are not. Taking the time to tag each open response will help you see trends and filter out the responses that are unhelpful.

Unlike questions with predefined answers, open-ended responses let users express unique ideas and use cases you may not be looking for. The tedium of reading thousands of response is always cut by eureka moments when users tell you something fascinating that changes your perspective on your app. These are the folks you want to pull out for follow-up interviews. Because you’ve already captured their email addresses when you set up your survey and your email, getting in touch will be a piece of cake.

Filter, compare, interview, and summarize; then share your findings with your colleagues. Reports are great for head honchos, but if you want to really inform and inspire, create a video, a poster series, or even a comic to communicate what you’ve learned. Want to get really fancy? Store your survey results in a centrally accessible location so anyone in your company can research and discover the insights they need to make more informed designs. 

Good design researchers discover valuable insights. Great design researchers turn those insights into stories.

Conclusion

As we enter the new year, it’s a great time to reflect on the work we’ve done in the past and how we can do better in the future. Without a doubt, designers working with a foundation of insights about customers can make more effective UIs. But designers aren’t the only ones who stand to gain from the data collected in an annual survey—anyone who makes things for or communicates with customers will find themselves empowered to do better work when they know more about the people they serve. The data you collect with your survey is a fantastic holiday gift to your colleagues, one that they’ll appreciate throughout the year.",2013,Aarron Walter,aarronwalter,2013-12-13T00:00:00+00:00,https://24ways.org/2013/data-driven-design-with-an-annual-survey/,design
4,Credits and Recognition,"A few weeks ago, I saw a friendly little tweet from a business congratulating a web agency on being nominated for an award. The business was quite happy for them and proud to boot — they commented on how the same agency designed their website, too.

What seemed like a nice little shout-out actually made me feel a little disappointed. Why? In reality, I knew that the web agency didn’t actually design the site — I did, when I worked at a different agency responsible for the overall branding and identity.

I certainly wasn’t disappointed at the business — after all, saying that someone designed your site when they were responsible for development is an easy mistake to make. Chances are, the person behind the tweets and status updates might not even know the difference between words like design and development. 

What really disappointed me was the reminder of how many web workers out there never explain their roles in a project when displaying work in a portfolio. If you’re strictly a developer and market yourself as such, there might be less room for confusion, but things can feel a little deceptive if you offer a wide range of services yet never credit the other players when collaboration is part of the game. Unfortunately, this was the case in this situation. Whatever happened to credit where credit’s due?

Advertising attribution

Have you ever thumbed through an advertising annual or browsed through the winners of an advertising awards website, like the campaign below from Kopenhagen Chocolate on Advertising Age? If so, it’s likely that you’ve noticed some big differences in how the work is credited.

 Everyone involved in a creative advertising project is mentioned.

Art directors, writers, creative directors, photographers, illustrators and, of course, the agency all get a fair shot at fifteen minutes of fame. Why can’t we take this same idea and introduce it to our own showcases?

Crediting on client sites

Ah, the good old days of web rings, guestbooks, and under construction GIFs, when slipping in a cheeky “designed by” link in the footer of your masterpiece was just another common practice. These days most clients, especially larger companies and corporations, aren’t willing to have any names on their site except their own. 

If you’d still like to leave a little proof of authorship on a website, consider adding a humans.txt file to the root of the site and, if possible, add an author tag in the <head> of the site:

<link type=""text/plain"" rel=""author"" href=""http://domain/humans.txt"">

It’s a great way to add more detailed information than just a meta name without being intrusive. The example on the humanstxt.org website serves to act as a guideline, but how much detail you add is completely up to you and your team.

 Part of the humans.txt file on humanstxt.org

Alternatively, you can use the HTML5 rel=""author"" attribute to link to information about the author of the page in the form of a mailto: address, a link to a contact form, or a separate authors page.

Crediting in portfolios

While humans.txt is a great approach when you’re authoring a site, it’s even more important to clearly define your role in your own portfolio. 

While I believe it’s proper etiquette to include the names of folks you collaborated with, sometimes it might not be necessary (or even possible) to list every single person, especially if you’ve worked with a large agency. 

“Fake it till you make it” is not a term that should apply to your portfolio. Clearly stating your own responsibilities means that nobody else browsing your work samples will assume that you did more than your actual share, and being ambiguous about your role isn’t fair to yourself, or others. 

Before adding any work to your portfolio, ensure that you have permission from your client. Even if you included a clause in your contract about being allowed to post your work online, it’s always best to double-check. Sometimes you might not know if your work has been officially launched, and leaking something before it’s ready is bound to make a client frown.

Examples

There are plenty of portfolios out there that we can use for inspiration. Here are some examples that I like from other folks in the web industry:

Anna Debenham

 In her portfolio, Anna outlines her responsibilities and those of others.

In the description, Anna clearly explains her duties of doing the HTML and CSS, along with performing research and testing the prototype in schools. She also credits Laura Kalbag for the design work.

Naomi Atkinson Design

The work portfolio of Naomi Atkinson Design is short and to the point — they were responsible for the iPhone app design and IA for Artspotter.

 The portfolio of Naomi Atkinson Design states clearly what they did.

Amber Weinberg

Amber Weinberg is strictly a developer, but a potential client could see her portfolio and assume she might be a designer as well. To avoid any misunderstandings, she states her roles up front in a section called “What I Did,” supported by examples of her code.

 Amber Weinberg sets out all her roles in each of her portfolio’s case studies.

What if someone doesn’t want to be credited?

Let’s face it — we’ve all been there. A project, for whatever reason, turns out to be an absolute disaster and we don’t feel like it’s an accurate representation of the quality of our work. 

If you’re crediting someone else but suspect they might rather pretend it never happened, be sure to drop them a line and ask if they’d like to be included. And, if someone contacts you and asks to remove their name, don’t feel offended — just politely remove it.

Get updating!

Now that the holiday season is almost here, many of you might be planning to set aside some time for personal projects. Grab yourself a gingerbread latte and get those portfolios up to date. Remember, It doesn’t have to be long-winded, just honest. Happy holidays!",2013,Geri Coady,gericoady,2013-12-16T00:00:00+00:00,https://24ways.org/2013/credits-and-recognition/,process
8,Coding Towards Accessibility,"“Can we make it AAA-compliant?” – does this question strike fear into your heart? Maybe for no other reason than because you will soon have to wade through the impenetrable WCAG documentation once again, to find out exactly what AAA-compliant means?

I’m not here to talk about that.

The Web Content Accessibility Guidelines are a comprehensive and peer-reviewed resource which we’re lucky to have at our fingertips. But they are also a pig to read, and they may have contributed to the sense of mystery and dread with which some developers associate the word accessibility.

This Christmas, I want to share with you some thoughts and some practical tips for building accessible interfaces which you can start using today, without having to do a ton of reading or changing your tools and workflow.

But first, let’s clear up a couple of misconceptions.

Dreary, flat experiences

I recently built a front-end framework for the Post Office. This was a great gig for a developer, but when I found out about my client’s stringent accessibility requirements I was concerned that I’d have to scale back what was quite a complex set of visual designs.

Sites like Jakob Neilsen’s old workhorse useit.com and even the pioneering GOV.UK may have to shoulder some of the blame for this. They put a premium on usability and accessibility over visual flourish. (Although, in fairness to Mr Neilsen, his new site nngroup.com is really quite a snazzy affair, comparatively.)

Of course, there are other reasons for these sites’ aesthetics — and it’s not because of the limitations of the form. You can make an accessible site look as glossy or as plain as you want it to look. It’s always our own ingenuity and attention to detail that are going to be the limiting factors.

Synecdoche

We must always guard against the tendency to assume that catering to screen readers means we have the whole accessibility ballgame covered. 

There’s so much more to accessibility than assistive technology, as you know. And within the field of assistive technology there are plenty of other devices for us to consider.

Planning to accommodate all these users and devices can be daunting. When I first started working in this field I thought that the breadth of technology was prohibitive. I didn’t even know what a screen reader looked like. (I assumed they were big and heavy, perhaps like an old typewriter, and certainly they would be expensive and difficult to fathom.) This is nonsense, of course. Screen reader emulators are readily available as browser extensions and can be activated in seconds. Chromevox and Fangs are both excellent and you should download one or the other right now.

But the really good news is that you can emulate many other types of assistive technology without downloading a byte. And this is where we move from misconceptions into some (hopefully) useful advice.

The mouse trap

The simplest and most effective way to improve your abilities as a developer of accessible interfaces is to unplug your mouse.

Keyboard operation has its own WCAG chapter, because most users of assistive technology are navigating the web using only their keyboards. You can go some way towards putting yourself into their shoes so easily — just by ditching a peripheral.

Learning this was a lightbulb moment for me. When I build interfaces I am constantly flicking between code and the browser, testing or viewing the changes I have made. Now, instead of checking a new element once, I check it twice: once with my mouse and then again without.

Don’t just :hover

The reality is that when you first start doing this you can find your site becomes unusable straightaway. It’s easy to lose track of which element is in focus as you hit the tab key repeatedly.

One of the easiest changes you can make to your coding practice is to add :focus and :active pseudo-classes to every hover state that you write. I’m still amazed at how many sites fail to provide a decent focus state for links (and despite previous 24 ways authors in 2007 and 2009 writing on this same issue!).

You may find that in some cases it makes sense to have something other than, or in addition to, the hover state on focus, but start with the hover state that your designer has taken the time to provide you with. It’s a tiny change and there is no downside. So instead of this:

.my-cool-link:hover {
	background-color: MistyRose ;	
}

…try writing this:

.my-cool-link:hover,
.my-cool-link:focus,
.my-cool-link:active {
	background-color: MistyRose ;	
}

I’ve toyed with the idea of making a Sass mixin to take care of this for me, but I haven’t yet. I worry that people reading my code won’t see that I’m explicitly defining my focus and active states so I take the hit and write my hover rules out longhand.

JavaScript can play, too

This was another revelation for me. Keyboard-only navigation doesn’t necessitate a JavaScript-free experience, and up-to-date screen readers can execute JavaScript. So we’re able to create complex JavaScript-driven interfaces which all users can interact with.

Some of the hard work has already been done for us. First, there are already conventions around keyboard-driven interfaces. Think about the last time you viewed a photo album on Facebook. You can use the arrow keys to switch between photos, and the escape key closes whichever lightbox-y UI thing Facebook is showing its photos in this week. Arrow keys (up/down as well as left/right) for progression through content; Escape to back out of something; Enter or space bar to indicate a positive intention — these are established keyboard conventions which we can apply to our interfaces to improve their accessiblity. 

Of course, by doing so we are improving our interfaces in general, giving all users the option to switch between keyboard and mouse actions as and when it suits them.

Second, this guy wants to help you out. Hans Hillen is a developer who has done a great deal of work around accessibility and JavaScript-powered interfaces. Along with The Paciello Group he has created a version of the jQuery UI library which has been fully optimised for keyboard navigation and screen reader use. It’s a fantastic reference which I revisit all the time 

I’m not a huge fan of the jQuery UI library. It’s a pain to style and the code is a bit bloated. So I’ve not used this demo as a code resource to copy wholesale. I use it by playing with the various components and seeing how they react to keyboard controls. Each component is also fully marked up with the relevant ARIA roles to improve screen reader announcement where possible (more on this below).

Coding for accessibility promotes good habits

This is a another observation around accessibility and JavaScript. I noticed an improvement in the structure and abstraction of my code when I started adding keyboard controls to my interface elements. 

Your code has to become more modular and event-driven, because any number of events could trigger the same interaction. A mouse-click, the Enter key and the space bar could all conceivably trigger the same open function on a collapsed accordion element. (And you want to keep things DRY, don’t you?) 

If you aren’t already in the habit of separating out your interface functionality into discrete functions, you will be soon.

var doSomethingCool = function(){
	// Do something cool here.
}

// Bind function to a button click - pretty vanilla
$('.myCoolButton').on('click', function(){
	doSomethingCool();
	return false;
});

// Bind the same function to a range of keypresses
$(document).keyup(function(e){
	switch(e.keyCode) {
		case 13: // enter
		case 32: // spacebar
			doSomethingCool();
			break;
		case 27: // escape
			doSomethingElse();
			break;
	}
});

To be honest, if you’re doing complex UI stuff with JavaScript these days, or if you’ve been building any responsive interfaces which rely on JavaScript, then you are most likely working with an application framework such as Backbone, Angular or Ember, so an abstraced and event-driven application structure will be familar to you. It should be super easy for you to start helping out your keyboard-only users if you aren’t already — just add a few more event bindings into your UI layer!

Manipulating the tab order

So, you’ve adjusted your mindset and now you test every change to your codebase using a keyboard as well as a mouse. You’ve applied all your hover states to :focus and :active so you can see where you’re tabbing on the page, and your interactive components react seamlessly to a mixture of mouse and keyboard commands. Feels good, right?

There’s another level of optimisation to consider: manipulating the tab order. Certain DOM elements are naturally part of the tab order, and others are excluded. Links and input elements are the main elements included in the tab order, and static elements like paragraphs and headings are excluded. What if you want to make a static element ‘tabbable’? 

A good example would be in an expandable accordion component. Each section of the accordion should be separated by a heading, and there’s no reason to make that heading into a link simply because it’s interactive.

<div class=""accordion-widget"">
	<h3>Tyrannosaurus</h3>
	<p>Tyrannosaurus; meaning ""tyrant lizard""...<p>

	<h3>Utahraptor</h3>
	<p>Utahraptor is a genus of theropod dinosaurs...<p>

	<h3>Dromiceiomimus</h3>
	<p>Ornithomimus is a genus of ornithomimid dinosaurs...<p>
</div>

Adding the heading elements to the tab order is trivial. We just set their tabindex attribute to zero. You could do this on the server or the client. I prefer to do it with JavaScript as part of the accordion setup and initialisation process.

$('.accordion-widget h3').attr('tabindex', '0');

You can apply this trick in reverse and take elements out of the tab order by setting their tabindex attribute to −1, or change the tab order completely by using other integers. This should be done with great care, if at all. You have to be sure that the markup you remove from the tab order comes out because it genuinely improves the keyboard interaction experience. This is hard to validate without user testing. The danger is that developers will try to sweep complicated parts of the UI under the carpet by taking them out of the tab order. This would be considered a dark pattern — at least on my team!

A farewell ARIA

This is where things can get complex, and I’m no expert on the ARIA specification: I feel like I’ve only dipped my toe into this aspect of coding for accessibility. But, as with WCAG, I’d like to demystify things a little bit to encourage you to look into this area further yourself.

ARIA roles are of most benefit to screen reader users, because they modify and augment screen reader announcements. 

Let’s take our dinosaur accordion from the previous section. The markup is semantic, so a screen reader that can’t handle JavaScript will announce all the content within the accordion, no problem.

But modern screen readers can deal with JavaScript, and this means that all the lovely dino information beneath each heading has probably been hidden on document.ready, when the accordion initialised. It might have been hidden using display:none, which prevents a screen reader from announcing content. If that’s as far as you have gone, then you’ve committed an accessibility sin by hiding content from screen readers. Your user will hear a set of headings being announced, with no content in between. It would sound something like this if you were using Chromevox:

> Tyrannosaurus. Heading Three.
> Utahraptor. Heading Three.
> Dromiceiomimus. Heading Three.

We can add some ARIA magic to the markup to improve this, using the tablist role. Start by adding a role of tablist to the widget, and roles of tab and tabpanel to the headings and paragraphs respectively. Set boolean values for aria-selected, aria-hidden and aria-expanded. The markup could end up looking something like this.

<div class=""accordion-widget"" role=""tablist"">
	<!-- T-rex -->	
	<h3 role=""tab"" 
		tabindex=""0"" 
		id=""tab-2"" 
		aria-controls=""panel-2"" 
		aria-selected=""false"">Utahraptor</h3>
	<p	role=""tabpanel"" 
		id=""panel-2"" 
		aria-labelledby=""tab-2"" 
		aria-expanded=""false"" 
		aria-hidden=""true"">Utahraptor is a genus of theropod dinosaurs...</p>
	<!-- Dromiceiomimus -->	
</div>

Now, if a screen reader user encounters this markup they will hear the following:

> Tyrannosaurus. Tab not selected; one of three.
> Utahraptor. Tab not selected; two of three.
> Dromiceiomimus. Tab not selected; three of three.

You could add arrow key events to help the user browse up and down the tab list items until they find one they like. 

Your accordion open() function should update the ARIA boolean values as well as adding whatever classes and animations you have built in as standard. Your users know that unselected tabs are meant to be interacted with, so if a user triggers the open function (say, by hitting Enter or the space bar on the second item) they will hear this:

> Utahraptor. Selected; two of three.

The paragraph element for the expanded item will not be hidden by your CSS, which means it will be announced as normal by the screen reader.

This kind of thing makes so much more sense when you have a working example to play with. Again, I refer you to the fantastic resource that Hans Hillen has put together: this is his take on an accessible accordion, on which much of my example is based.

Conclusion

Getting complex interfaces right for all of your users can be difficult — there’s no point pretending otherwise. And there’s no substitute for user testing with real users who navigate the web using assistive technology every day. This kind of testing can be time-consuming to recruit for and to conduct. On top of this, we now have accessibility on mobile devices to contend with. That’s a huge area in itself, and it’s one which I have not yet had a chance to research properly.

So, there’s lots to learn, and there’s lots to do to get it right. But don’t be disheartened. If you have read this far then I’ll leave you with one final piece of advice: don’t wait.

Don’t wait until you’re building a site which mandates AAA-compliance to try this stuff out. Don’t wait for a client with the will or the budget to conduct the full spectrum of user testing to come along. Unplug your mouse, and start playing with your interfaces in a new way. You’ll be surprised at the things that you learn and the issues you uncover. 

And the next time an true accessibility project comes along, you will be way ahead of the game.",2013,Charlie Perrins,charlieperrins,2013-12-03T00:00:00+00:00,https://24ways.org/2013/coding-towards-accessibility/,code
17,Bringing Design and Research Closer Together,"The ‘should designers be able to code’ debate has raged for some time, but I’m interested in another debate: should designers be able to research? 

Are you a designer who can do research? Good research and the insights you uncover inspire fresh ways of thinking and get your creative juices flowing. Good research brings clarity to a woolly brief. Audience insight helps sharpen your focus on what’s really important. Experimentation through research and design brings a sense of playfulness and curiosity to your work. Good research helps you do good design.

Being a web designer today is pretty tough, particularly if you’re a freelancer and work on your own. There are so many new ideas, approaches to workflow and trends and tools to keep up with. How do you decide which things to do and which to ignore? A modern web designer needs to be able to consider the needs of the audience, design appropriate IAs and layouts, choose colour palettes, pick appropriate typefaces and type layouts, wrangle with content, style, code, dabble in SEO, and the list goes on and on. Not only that, but today’s web designer also has to keep up with the latest talking points in the industry: responsive design, Agile, accessibility, Sass, Git, lean UX, content first, mobile first, blah blah blah. Any good web designer doesn’t need to be persuaded about the merits of including research in their toolkit, but do you really have time to include research too? 

Who is responsible for research?

Generally, research in the web industry forms part of other disciplines and isn’t so much a discipline in its own right. It’s very often thought of as part of UX, or activities that make up a process such as IA or content strategy. Research is often undertaken by UX designers, information architects or content strategists and isn’t something designers or developers get that involved in. Some people lump all of these activities together and label it design research and have design researchers to do it. Some companies, such as the one I run with my husband Mark, are lucky enough to have someone with specialist research knowledge (yup, that would be me folks) who can lead all or most of the research work undertaken by the company. See also Mule Design, GOV.UK, the BBC, Mailchimp, Facebook and Twitter. 

What if you’re not lucky enough to have your own researcher or team of researchers? Often research is the kind of thing that’s nice to have, or it can be cut from scope when doing the budget dance with a client. It often forms part of the discovery phase of a project and sometimes just becomes a tick-box exercise. But research isn’t just user testing and it shouldn’t just live in a report on Basecamp that no one reads. I would argue that research and experimentation is a way of working or an approach to how you design. Research can be used during the whole design process and must be a vital part of a designer’s workflow on every project. Even if you work in a small studio, you can still create a culture of audience insight. Even if you work on your own, you can still absorb yourself in as much audience data as you can throughout the project life cycle. Here’s how.

Research is everyone’s job

There is a subtle difference between writing a research report and delivering it to a client, and them actually using it and applying the insights to their thought process. In my experience of working in the audiences team at the BBC, research was most effective when the role was embedded in the production team and insights were used as part of the editorial process.

In this section I’ll talk through some common problems you might encounter in a typical project life cycle and show you ways you can use research to help you. For the sake of this article, let’s imagine that we’re talking about a particular project here and not ongoing product development. The same principles can of course be applied then, but even if you work in-house rather than on the agency side, you’re probably used to working on distinct projects or phases of work.

1. Problem: I want to come up with a new product idea. 

Solution: Inspiration through insights.

Before you begin a new project, a good way of quickly absorbing all the existing knowledge that there maybe about a theme, product type or website is to literally surround yourself with it. This is especially relevant for new ideas or product development. Create an incident room if you can: fill the walls of your meeting room, the walls near your desk, or even just use a pinboard or online pinboard if space is tight or you’re working with a dispersed team. The same process can be used throughout a project’s or product life cycle — read about how MailChimp has applied this idea. 

Let’s take a new product idea as an example. Say you wanted to develop a responsive tool for web designers but you weren’t sure what aspect of responsive design to focus on. First of all, you should pose a hypothesis or problem statement to gather ideas around. For example: “How to speed up a designer’s responsive workflow.” You would then need to gather insights around this topic. You could run some interviews with freelance designers about how they work responsively. You could shadow a development team for the day to understand their processes. You could observe conversations on Twitter or IRC or wherever your target audience interact to see what people talk about. You could search out industry data and articles currently available.

The next stage is to comb through this data and extract insights from it. You can use good old Post-it notes and a sharpie: capture one insight or thought per Post-it. If one insight leads into another, use two Post-its. The objective is volume. Try to ensure clarity in each Post-it so you don’t have to go back and reference material again (maybe you could use a key if you think it’ll get confusing).



After this, stick them all up and synthesise the same way you would for any kind of cluster or affinity sort. Organise into broad themes. These themes then become springboards for further exploration and idea generation. You might see a gap or opportunity in one particular area, both from a workflow perspective but also from a business perspective. Bingo. Your insights then become the fuel for ideas generation.

This method doesn’t just have to be used for new products — it works particularly well in a discovery phase for new projects or for new features in an existing product. We’re doing something similar for our own responsive tool, Gridset at the moment.

2. Problem: You’re starting a new project and need to know the basics before you get headlong into designing or building. 

Solution: Quantitative survey.

Common questions might be:


	Who are the users?
	How many are there?
	What are they like?
	Why do they use the site?
	What do they need from the site?
	What are their goals?


Print out and stick up what you already know and have in your project space or ‘incident room’: any reports you have found or been given, analytics graphs, personas, pen portraits, as well as screengrabs of the current website, product or branding. Spend time looking through it all and identify the gaps. 

If you have very little existing audience data, a quick and easy way to get some baseline information is to run a quick user survey on a current website. You can establish basic demographic information, appreciation and views of the website as it stands, as well as delve a little deeper into needs and wants. This is also vital if you want some kind of trackable measures to go back to once you have designed and built your shiny new website for your client — read more in my article for 24 ways last year.)



We use surveys a lot at Mark Boulton Design for our client work. Here’s a screen grab of one we ran in March on http://info.cern.ch before we redesigned the site and did the work on the First Website Project. We repeated the survey after the new website went live and were able to compare the results. Both surveys were a great source of insight to the project team as well as for the project stakeholders who needed to pitch the idea of the hack days and fundraise for them.



Once you’ve run your survey, you should always write up a short summary for yourself and your client to refer to. If you’re not a trained researcher, you should try to read up on analysis techniques or data visualisation. It can be easy to misinterpret data and make it bend to the story you are trying to tell. You should be looking for the story in the data and present it without bias. 

If you’re using the ‘incident room’ method I mentioned earlier on, you can also extract the insights onto post it notes and add them to your growing body of knowledge.

3. Problem: You have a prototype of a new design and you need some feedback from real users. 

Solution: User interviews and task based testing.

Interviewing is a staple research method that every designer should master as it can be used throughout a project life cycle. Erika Hall recently wrote a great article on the basics for A List Apart. From stakeholder interviews in a discovery phase, to initial user research, right through to task based testing and iteration, interviews can be enormously helpful. They are very time-consuming, however, and although speaking to someone is better than speaking to no one, it’s always better to plan to do a few interviews at once, rather than one or two. I generally find that patterns only start to emerge after I’ve spoken to 4 or 5 people. Interviews are another thing we do a lot of at Mark Boulton Design. Most of the interviews we do are remote due to the location of our clients and their users. 



Rigour is an important consideration in all research activities and especially if you’re a non-researcher. Interviews particularly can be easily skewed by an inexperienced facilitator, which is why pairing can be a good approach. Building rapport, questioning, time keeping, note taking and thinking on your feet can be difficult to do all at once, so having a colleague take notes while you concentrate on leading the conversation can work really well. It’s important for the note taker to sit in on more than one interview so that they get a more rounded view of the feedback. The same person should also be involved in the analysis of the data. 



Interviews can be analysed and written up in a report or summary as with other types of research. I often use the same kind of collaborative process detailed earlier for deciding on themes, particularly if multiple members of the team have been involved in interviewing. 

Interviews are particularly useful for our incident room and can provide much colour and insight to an exploratory process. I often find verbatim quotes to be the most insightful type of data. You might find that an inexperienced researcher (or designer who is used to solving problems) will jump to interpretation too soon and forget to just listen to what the interviewee is saying. Capturing the exact form of words a person uses can help get away from this.

4. Problem: How successful have I been with this new design? 

Solution: Key performance indicators

Once your new design has been realised, it’s important to evaluate it. What works, what doesn’t work so well? As well as a straightforward design crit, don’t forget to introduce audience insights into a review meeting or project wash up. 



Work out what your KPIs — your key performance indicators — will be beforehand and then you can start to track them over time. For example, number of visits, appreciation of the site, willingness to recommend the site to a friend, number of sales, and number of conversions are all sensible measures to track. Interviews can again be helpful but cold, hard numbers are often better here. Read Corey Vilhauer’s take on this on A List Apart.

Consistency is key here. If you have looked at your analytics and done a survey beforehand, you will have a baseline to start from. Don’t keep changing your measures and questions, or your data will not be comparable. Pick a few key questions or a set of measures, create a survey and then run it once a month, once a quarter, every six months or annually. You’ll start to see changes over time as the design beds in. You may see seasonal trends and spot patterns in the data related to other activities like marketing, promotion and so on. Keeping a record of all of this will increase your understanding of your audience. We’ve created a satisfaction survey for Gridset with a number of measures that we track on an ongoing basis. MailChimp has also created an annual survey with the aim of tracking their audience measures over time

Anyone can do research

Research can be brought into the project life cycle at any stage. And of course, anyone can do research — you don’t need to be a researcher. Some of the main skills most designers possess are also key research skills: inquisitive nature, problem solving, playfulness, empathy, and so on.

We have a small team at Mark Boulton Design. Most of the team are designers and the rest of us focus on supporting the team and clients both in terms of billable work (research, content strategy, project management) as well as the non-billable things like finance and studio management.

Despite my best intentions, in the past I’ve undertaken research for clients in isolation — first being briefed by the design lead, carrying out the research and then delivering the findings back, trusting the design team to take the findings on board. This was often due to time and availability of resources.

We’ve been trying hard to join up our processes and collaborate even more across the team. Undertaking heuristic or design reviews collaboratively; taking part in frequent critiques of our work and the work of others together; pairing a researcher and a designer to run interviews; workshopping results from interviews to come up with recommendations; working closely together on questionnaire design; shadowing each other on tasks that don’t fall within our core skills. A little thing like moving our desks around has also helped us have more conversations that we can all be a part of.



I’ve come to the conclusion that my role as the research director at Mark Boulton Design is actually a facilitator of research. As well as carrying out research, I am responsible for ensuring that research happens consistently across the team. I am responsible for empowering and training our designers so they feel confident in carrying out their own user, audience or design research for clients. So they know what to look for, when to listen, when to probe and when to take note of something. So they know how to look for themes, how to synthesise insights from research and how to apply them to their work.

Better research leads to better design

So, are you a designer who can do research? Are you a researcher who can design? The best designers are a lucky combination of researcher and designer. If you’re not one of those, look at ways of enhancing the skills you lack. Because there’s no doubt in my mind, that becoming a better researcher will make you a better designer.

23,Animating Vectors with SVG,"It is almost 2014 and fifteen years ago the W3C started to develop a web-based scalable vector graphics (SVG) format. As web technologies go, this one is pretty old and well entrenched. 

See the Pen yJflC by Drew McLellan (@drewm) on CodePen


Embed not working on your device? Try direct. 

Unlike rasterized images, SVG files will stay crisp and sharp at any resolution. With high-DPI phones, tablets and monitors, all those rasterized icons are starting to look a bit old and blocky. There are several options to get simpler, decorative pieces to render smoothly and respond to various device widths, shapes and sizes. Symbol fonts are one option; the other is SVG.

I’m a big fan of SVG. SVG is an XML format, which means it is possible to write by hand or to script. The most common way to create an SVG file is through the use of various drawing applications like Illustrator, Inkscape or Sketch. All of them open and save the SVG format.

But, if SVG is so great, why doesn’t it get more attention?

The simple answer is that for a long time it wasn’t well supported, so no one touched the technology. SVG’s adoption has always been hampered by browser support, but that’s not the case any more. Every modern browser (at least three versions back) supports SVG. Even IE9. 

Although the browsers support SVG, it is implemented in many different ways.

SVG in HTML

Some browsers allow you to embed SVG right in the HTML: the <svg> element. Treating SVG as a first-class citizen works — sometimes. Another way to embed SVG is via the <img> element; using the src attribute, you can refer to an SVG file. Again, this only works sometimes and leaves you in a tight space if you need to have a fallback for older browsers. The most common solution is to use the <object> element, with the data attribute referencing the SVG file. When a browser does not support this, it falls back to the content inside the <object>. This could be a rasterized fallback <img>. This method gets you the best of both worlds: a nice vector image with an alternative rasterized image for browsers that don’t support SVG. The downside is that you need to manage both formats, and some browsers will download both the SVG and the rasterized version, becoming a performance problem.

Alexey Ten came up with a brilliant little trick that uses inline SVG combined with an SVG <image> element. This has an SVG href pointing to the vector SVG representation and a src attribute to the rasterized version. Older browsers will rewrite the <image> element as <img> and use the rasterized src attribute, but modern browsers will show the vector SVG.

<svg width=""96"" height=""96"">
    <image xlink:href=""svg.svg"" src=""svg.png"" width=""96"" height=""96""/>
</svg>

It is a great workaround for most situations. You will have to determine the browsers you want or need to support and consider performance issues to decide which method is best for you.

So it can be used in HTML. Why?

There are two compelling reasons why vector graphics in the form of icons and symbols are going to be important on the web. With higher resolution screens, going from 72dpi to 200, 300, even over 400dpi, your rasterized icons are looking a little too blocky. As we zoom and print, we expect the visuals on the site to also stay smooth and crisp.

The other main reason vector graphics are useful is scaling. As responsive websites become the norm, we need a way to dynamically readjust the heights, widths and styles of various elements. SVG handles this perfectly, since vectors remain smooth when changing size.

SVG files are text-based, so they’re small and can be gzipped nicely. There are also techniques for creating SVG sprites to further squeeze out performance gains. But SVG really shines when you begin to couple it with JavaScript. Since SVG elements are part of the DOM, they can be interacted with just like any other element you are used to.

The folks at Vox Media had an ingenious little trick with their SVG for a Playstation and Xbox One reviews. I’ve used the same technique for the 24 ways example. Vox Media spent a lot of time creating SVG line art of the two consoles, but once in place the artwork scaled and resized beautifully. 

They still had another trick up their sleeves. In their example, they knew each console was line art, so they used SVG’s line dash property to simulate the lines being drawn by animating the growth of the line by small percentage increments until the lines were complete.

This is a great example of a situation where the alternatives wouldn’t be as straightforward to implement. Using an animated GIF would create a heavy file since it would need to contain all the frames of the animation at a large size to permit scaling; even then, smooth aliasing would be lost. canvas and plenty of JavaScript would be another alternative, but this is a rasterized format. It would need be redrawn at each scale, which is certainly possible, but smoothness would be lost when zooming or printing.

The HTML, SVG and JavaScript for this example is less than 4KB! Let’s have a quick look at the code:

<script>
var current_frame = 0;
var total_frames = 60;
var path = new Array();
var length = new Array();
for(var i=0; i<4;i++){
	path[i] = document.getElementById('i'+i);
	l = path[i].getTotalLength();
	length[i] = l;
	path[i].style.strokeDasharray = l + ' ' + l; 
	path[i].style.strokeDashoffset = l;
}
var handle = 0;

var draw = function() {
   var progress = current_frame/total_frames;
   if (progress > 1) {
     window.cancelAnimationFrame(handle);
   } else {
     current_frame++;
     for(var j=0; j<path.length;j++){
	     path[j].style.strokeDashoffset = Math.floor(length[j] * (1 - progress));
     }
     handle = window.requestAnimationFrame(draw);
   }
};
draw();
</script>

First, we need to initialize a few variables to set the current frame, the number of frames, how fast the animation will run, and we get each of the paths based on their IDs. With those paths, we set the dash and dash offset.

path[i].style.strokeDasharray = l + ' ' + l; 
path[i].style.strokeDashoffset = l;

We start the line as a dash, which effectively makes it blank or invisible.

Next, we move to the draw() function. This is where the magic happens. We want to increment the frame to move us forward in the animation and check it’s not finished. If it continues, we then take a percentage of the distance based on the frame and then set the dash offset to this new percentage. This gives the illusion that the line is being drawn. Then we have an animation callback, which starts the draw process over again.

That’s it! It will work with any SVG <path> element that you can draw.

Libraries to get you started

If you aren’t sure where to start with SVG, there are several libraries out there to help. They also abstract all browser compatibility issues to make your life easier.

You can also get most vector applications to export SVG. This means that you can continue your normal workflows, but instead of flattening the image as a PNG or bringing it over to Photoshop to rasterize, you can keep all your hard work as vectors and reap the benefits of SVG.",2013,Brian Suda,briansuda,2013-12-07T00:00:00+00:00,https://24ways.org/2013/animating-vectors-with-svg/,
94,Using Questionnaires for Design Research,"How do you ask the right questions? 

In this article, I share a bunch of tips and practical advice on how to write and use your own surveys for design research.

I’m an audience researcher – I’m not a designer or developer. I’ve spent much of the last thirteen years working with audience data both in creative agencies and on the client-side. I’m also a member of the Market Research Society. I run user surveys and undertake user research for our clients at the design studio I run with my husband – Mark Boulton Design.

So let’s get started!

Who are you designing for?

Good web designers and developers appreciate the importance of understanding the audience they are designing or building a website or app for. I’m assuming that because you are reading a quality publication like 24 ways that you fall into this category, and so I won’t begin this article with a lecture.

Suffice it to say, it’s a good idea to involve research of some sort during the life cycle of every project you undertake. I don’t just mean visual or competitor research, which of course is also very important. I mean looking at or finding your own audience or user data. Whether that be auditing existing data or research available from the client, carrying out user interviews, A/B testing, or conducting a simple questionnaire with users, any research is better than none. If you create personas as a design tool, they should always be based on research, so you will need to have plenty of data to hand for that.

Where do I start?

In the initial kick-off stages of a project, it’s a good idea to start by asking your client (when working in-house you still have a client – you might even be the client) what research or audience data they have available. Some will have loads – analytics, surveys, focus groups and insights – from talking to customers. Some won’t have much at all and you’ll be hard pressed to find out much about the audience. It’s best to review existing research first without rushing headlong into doing new research. Get a picture of what the data tells you and perhaps get this into a document – who, what, why and how are they using this website or app? What gaps are there in existing research? What else do you need to know? Then you can decide what else you need to do to plug these gaps. Think about the information first before deciding on the methodology. The rest of my article talks mostly about running self-completion online surveys. You can of course do face-to-face surveys, self-completion written questionnaires or phone polls, but I won’t cover those here. That’s for another article.

Why run a survey?

Surveys are great for getting a broad picture of your audience. As long as they are designed carefully, you can create an overview of them, how they use the site and their opinions of it, with an idea of which parts of this picture are more important than others. By using a limited amount of open-ended questions, you can also get some more qualitative feedback or insights on your website or app. The clients we work with surprisingly often don’t have much in the way of audience research available, even basic analytics, so I will often suggest running a short survey, just to create a picture of who is out there.

OK, what should I do first?

Before you rush into writing questions, stop and think about what you’re trying to find out. Remember being in school when you studied science and you had to propose a hypothesis? This could be a starting point – something to prove or disprove. Or, even better, write a research brief. It doesn’t have to be long; it can be just a sentence that encapsulates what you’re trying to do, like a good creative brief. For the purposes of this article, I created a short, slightly silly survey on Christmas and beliefs in Father Christmas.

My research brief was:


	To find out more about people’s beliefs about Father Christmas and their experiences of Christmas.


Inevitably, as you start thinking of what questions to ask, you will find that you go off at tangents or your client will want you to add in everything but the kitchen sink. In order for your questionnaire not to get too long and lose focus, you could write lists of what it is and what it’s not. This is how I’d apply it to my Christmas questionnaire example:

What it is about


	How people communicate with Father Christmas
	If someone’s background has affected their likelihood of believing in Father Christmas


What it is not about


	What colour to change Father Christmas’s coat to
	Father Christmas’s elves


Let’s get down to business: the questions. 

Kinds of questions

There are two basic kinds of questions: open-ended and closed. Closed questions limit answers by giving the respondent a number of predefined lists of options to choose from. Typically, these are multiple-choice questions with a list of responses. You can either select one or tick all that apply. Another useful type of closed question I often use is a rating scale, where a respondent can assess a situation along a continuum of values. These can also be useful as a measure of advocacy or strength of feeling about something. There is a standard measure called the Net Promoter score, which measures how likely someone is to recommend your product or service to a friend or acquaintance. It’s a useful benchmark as you can compare your scores to others in a similar sector.



Open-ended questions often take the form of a statement which requires a response. Generally, respondents are given a text box to fill in. It’s useful to limit this in some way so that people have an idea of how long the expected response should be; for example, a single line for an email address (Q18), or a larger text area for a longer response (Q6).

If you plan to send your survey out to a large number of people, I would suggest using mostly closed questions, unless you want to spend a long time wading through comments and hand-coded responses. I’d always advise adding a general request at the end of a survey (‘Is there anything else you’d like to tell us?’). You’d be surprised how many interesting and insightful comments people will add.

There are times when it’s better to provide an open-ended text box rather than a predefined list makes assumptions about your audience’s groupings. For example, we ran a short survey for our Gridset beta testers and rather than assume we knew who they were, we decided to ask an open-ended question: “What is your current job title?”



The analysis took quite a bit longer than responses using a predefined list, but it meant that we were able to make sure we didn’t miss anyone. And next time we run a survey for Gridset, I can use the responses gathered from this survey to help create a predefined list to make analysis easier.

What to ask

The questions to ask depend on what you want to know, but your brief and lists of what the survey is and isn’t should help here. I always ask the design team and client to give me ideas of what they are interested in finding out, and combine this with a mix of new and standard questions I have used in other surveys. I find Survey Monkey’s question bank a very useful source of example questions and help with tricky wording.

I always include simple demographics so I can compare my results to the population at large or internet users as a whole – just going on age, gender and location can be quite illuminating. For example, with the Christmas survey, I can see that the respondents were typical of the online design and dev community, mainly young and male.

If appropriate, I add questions on disability, ethnic background, religion and community of interest. Questions about ethnicity, religion, sexual preference, disability and other sensitive subjects can feel awkward and difficult to ask. This is not a good reason to not ask them. Perhaps you’re working for a public sector client, like a local council, so it’s likely you will need to consider groups of people who maybe under-represented, who may have differing views to others, or who you need to look at specifically as a subset.

How to ask

Although they may seem clunky and wordy, it’s often best to use the census wording or professional body wording for such demographic questions. For example, I used the UK census 2011 wording for Wales on my Christmas questionnaire in my questions on religion [PDF] (Q16) and ethnicity [PDF] (Q17). I had to adapt them slightly for the Survey Monkey format – self-completion online, rather than pen and paper – which is why “White Welsh” came up as the first option for the ethnicity question. For similar questions for US audiences, try the Census Bureau website.

When conducting a survey for a project that has a global audience, you need to consider who your primary audience is. For example, I recently created a questionnaire for a global news website. A large proportion of its audience is based in the USA, so I was careful to word things in a way Americans would find familiar. I used the US ethnic background census question wording and options, and looked at data for US competitor news websites to decide which to include.

You should also consider people whose first language isn’t English. Working as an audience researcher at BBC Wales, every survey we did was bilingual. I’ve also recently run a user survey in Arabic using Google Forms. During this project, we found that while Survey Monkey supports different languages, including Arabic, the text ran left to right with no option to change it to right to left – an essential when it comes to reading Arabic! If research is a deliverable in a client project, and you know you’ll need to conduct it in a foreign language, always build in extra time for translation at both the questionnaire design and analysis stages. Make sure you also allow for plenty of checks. In this case we had to change to Google Forms after initially creating our survey with Survey Monkey to get the functionality we needed.

Look and feel

Think about the survey as another way your audience will experience your brand. Take care getting the tone of voice right. There are plenty of great articles and books out there about tone of voice – try Letting Go of the Words by Ginny Redish for starters, or Brand Language by Liz Doig. The basic rule of thumb is to sound like a human, and use clear and friendly language. If, like me, you are lucky enough to work with journalists or copy editors, you should ask for their help, particularly in the preamble, linking text and closing statements. I find it helpful to break my questions down into sections and to have a page for each. I then have an introductory piece of text for each section to guide the respondent through the survey.

You should also make sure you check with your designers how your survey looks – use a company logo and branding, and make the typography legible. Many survey apps like Survey Monkey and Google Forms have a progress bar. This is helpful for users to see how far through your survey they are. I generally time the survey and give an indication in the preamble: “This survey will only take five minutes of your time.”

You also need to think about how you will technically serve the questionnaire. For example, will it be via email, social media, a pop-up or lightbox on your website, or (not recommended but possible) in an ad space?

Ethical considerations

Something else to think about are any local laws that govern how you collect and store data, such as the Data Protection Act in the UK. As a member of the Market Research Society, I am also obliged to consider its guidelines, but even if you’re not, it’s always a good idea to deal with personal data ethically.

If you collect personal data that can identify individuals, you must ask their permission to share it with others, and store it securely for no longer than two years. If you want to contact people afterwards, you must ask for their permission. If you ask for email addresses, as I did in question 18, you have a ready-made sample for a further survey, interviews or focus groups. Remember, you shouldn’t survey people under sixteen years old without the permission of their parents or legal guardians, so if you know your website is likely to be used by children, you must ask for verification of age early on, and your survey should close someone answers that they are under sixteen. The ESOMAR guidelines for online research [PDF] are well worth reading, as they go into detail about such issues, as well as privacy guidelines – using cookies, storing IP addresses, and so on.

Tools

Unless you work in-house and have proprietary software, or at a market research agency and you’re using specialist software such as Snap or IBM SPSS Statistics (previously just SPSS), you will need to use a good tool to run your survey, collect your responses and, ideally, help with the analysis. I like Survey Monkey because of the question bank and analysis tools. The software graphs your results and does simple cross-tabbing and filtering. What this means is you can slice the data in more interesting ways and delve a bit deeper. For example, in the Gridset questionnaire I mentioned earlier, I cross-tabbed responses to questions against whether a person worked in-house, for an agency or as a freelancer. 

Other well known online tools that I also use from time to time are Wufoo and Google Forms. Smart Surveys is a similar service to Survey Monkey and it’s used by many leading brands in the UK. Snap Surveys mentioned above is a well-established player in the market research scene, used a lot for face-to-face surveys and also on tablets and smartphones.

Analysis

Analysis is often overlooked but is as important as the design of the questionnaire. Don’t just rely on looking at the summary report and charts generated as standard by your form or survey software. Spend time with your data. Spend at least a week now and then if you can, looking at the data. Keep coming back to it and tweaking or cutting it a different way to see if there are any different pictures. Slice it up in different ways to reveal new insights. Here is the data from my dummy survey (apart from the open-ended responses). 

For open-ended questions, you can analyse collaboratively. Print and cut out the open-ended responses and do a cluster analysis or affinity sort with a colleague. 



Discussing the comments helps you to understand them. You will also find the design team are more likely to buy into the research as they have uncovered the insights for themselves. Always make sure to treat open-ended responses sensitively and don’t share anything publicly in a way that identifies the respondent.

Write a report

Never hand over a dataset to your client without a summary of the findings. Data on its own can be skewed to suit the reader’s needs, and not everyone is able to find the story in a dataset. Even if it’s not a deliverable, it’s always a good idea to capture your findings in a report of some sort. Use graphs sparingly to show really interesting things or to aid the reader’s understanding. I have written a quick dummy report using the data from the Christmas questionnaire so you can see how it’s done.

I highly recommend Brian Suda’s book A Practical Guide to Designing with Data for tips on how to present data effectively, but that’s a subject that benefits a whole article (indeed book) in itself. 

I am not a designer. I am a researcher, so I never write design recommendations in a report unless they have been talked about or suggested by the designers I work with. More often, I write up the results and we talk about them and what impact they have on the project or design. Often they lead to more questions or further research.

So that’s it: a brief introduction to using questionnaires for design research. Here’s a quick summary to remind you what I have talked about, and a list of resources if you’re interested in reading further.

Top 10 things to remember when using questionnaires for design research:


	Start by auditing existing research to identify gaps in data.
	Write a research brief. Work out exactly what you’re trying to find out – what is the survey about, and what is it not about?
	The two basic kinds of questions are open-ended and closed.
	Closed questions limit responses by giving the respondent a number of predefined lists of options to choose from (multiple choice, rating scales, and so on).
	Open-ended questions are often in the form of a statement which requires a response. Always ask one at the end of a questionnaire.
	Always include simple demographics to enable you to compare your sample against the population in general.
	It’s best to use official census or professional body wording for questions on ethnicity, disability and religion.
	Be sure to think carefully about your tone of voice and the look of your questionnaire.
	Pay attention to guidelines and laws on storing personal data, cookies and privacy.
	Invest plenty of time in analysis and report writing. Don’t just look at the obvious – dig deep for more interesting insights.

96,Unwrapping the Wii U Browser,"The Wii U was released on 18 November 2012 in the US, and 30 November in the UK. It’s the first eighth generation home console, the first mainstream second-screen device, and it has some really impressive browser specs.

Consoles are not just for games now: they’re marketed as complete entertainment solutions. Internet connectivity and browser functionality have gone from a nice-to-have feature in game consoles to a selling point. In Nintendo’s case, they see it as a challenge to design an experience that’s better than browsing on a desktop.


	Let’s make a browser that users can use on a daily basis, something that can really handle everything we’ve come to expect from a browser and do it more naturally.
Sasaki – Iwata Asks on Nintendo.com


With 11% of people using console browsers to visit websites, it’s important to consider these devices right from the start of projects. Browsing the web on a TV or handheld console is a very different experience to browsing on a desktop or a mobile phone, and has many usability implications.

Console browser testing

When I’m testing a console browser, one of the first things I do is run Niels Leenheer’s HTML5 test and Lea Verou’s CSS3 test. I use these benchmarks as a rough comparison of the standards each browser supports.

In October, IE9 came out for the Xbox 360, scoring 120/500 in the HTML5 test and 32% in the CSS3 test. The PS Vita also had an update to its browser in recent weeks, jumping from 58/500 to 243/500 in the HTML5 test, and 32% to 55% in the CSS3 test. Manufacturers have been stepping up their game, trying to make their browsing experiences better.

To give you an idea of how the Wii U currently compares to other devices, here are the test results of the other TV consoles I’ve tested. I’ve written more in-depth notes on TV and portable console browsers separately.

Wii U2012258/50048%Runs a Netfront browser (WebKit).

The Wii U browser is Nintendo’s fifth attempt at a console browser. Based on these tests, it’s already looking promising.

Why console browsers used to suck

It takes a lot of system memory to run a good browser, and the problem of older consoles is that they don’t have much memory available. The original Nintendo DS needs a memory expansion pack just to run the browser, because the 4MB it has on board isn’t enough. I noticed that even on newer devices, some sites fail to load because the system runs out of memory.

The Wii came out six years ago with an Opera browser. Still being used today and with such low resources available, the latest browser features can’t reasonably be supported. There’s also pressure to add features such as tabs, and enable gamers to use the browser while a game is paused. Nintendo’s browser team have the advantage of higher specs to play with on their new console (1GB of memory dedicated to games, 1GB for the system), which makes it easier to support the latest standards. But it’s still a challenge to fit everything in.


	…even though we have more memory, the amount of memory we can use for the browser is limited compared to a PC, so we’ve worked in ways that efficiently allocates the available memory per tab. To work on this, the experience working on the browser for the Nintendo 3DS system under a limited memory constraint helped us greatly.

In the box

The Wii U consists of a console unit which plugs into a TV (the first to support HD), and a wireless controller known as a gamepad. The gamepad is a lot bigger than typical TV console controllers, and it has a touchscreen on the front. The touchscreen is resistive, responding to pressure rather than electrical current. It’s intended to be used with a stylus (provided) but fingers can be used.

It might look a bit like one, but the gamepad isn’t a portable console designed to be taken out like the PS Vita. The gamepad can be used as a standalone screen with the TV switched off, as long as it’s within range of the console unit – it basically piggybacks off it.



It’s surprisingly lightweight for its size. It has a wealth of detectors including 9-axis control. Sensors wake the device from sleep when it’s picked up. There’s also a camera on the front, and a headphone port and speakers, with audio coming through both the TV and the gamepad giving a surround sound feel.

Up to six tabs can be opened at once, and the browser can be used while games are paused. There’s a really nice little feature here – the current game’s name is saved as a search option, so it’s really quick to look up contextual content such as walk-throughs.

Controls

Only one gamepad can be used to control the browser, but if there are Wiimotes connected, they can be used as pointers. This doesn’t let the user do anything except point (they each get a little hand icon with a number on it displayed on the screen), but it’s interesting that multiple people can be interacting with a site at once.



See a bigger version

The gamepad can also be used as a simple TV remote control, with basic functions such as bringing up the programme guide, adjusting volume and changing channel. I found the simplified interface much more usable than a full-featured remote control.



I’m used to scrolling being sluggish on consoles, but the Wii U feels almost as snappy as a desktop browser. Sites load considerably faster compared with others I’ve tested.

Tilt-scroll

Holding down ZL and ZR while tilting the screen activates an Instapaper-style tilt to scroll for going up and down the page quickly, useful for navigating very long pages.

Second screen

The TV mirrors most of what’s on the gamepad, although the TV screen just displays the contents of the browser window, while the gamepad displays the site along with the browser toolbar.

When the user with the gamepad is typing, the keyboard is hidden from the TV screen – there’s just a bit of text at the top indicating what’s happening on the gamepad.

Pressing X draws an on-screen curtain over the TV, hiding the content that’s on the gamepad from the TV. Pressing X again opens the curtains, revealing what’s on the gamepad. Holding the button down plays a drumroll before it’s released and the curtains are opened. I can imagine this being used in meetings as a fun presentation tool.




	In a sense, browsing is a personal activity, but you get the idea that people will be coming and going through the room. When I first saw the curtain function, it made a huge impression on me. I walked around with it all over the company saying, “They’ve really come up with something amazing!”

Text

Writing text

Unlike the capacitive screens on smartphones, the Wii U’s resistive screen needs to be pressed harder than you’re probably used to for registering a touch event. The gamepad screen is big, which makes it much easier to type on this device than other handheld consoles, even without the stylus. It’s still more fiddly than a full-sized keyboard though. When you’re designing forms, consider the extra difficulty console users experience.



Although TV screens are physically big, they are typically viewed from further away than desktop screens. This makes readability an issue, so Nintendo have provided not one, but four ways to zoom in and out:


	Double-tapping on the screen.
	Tapping the on-screen zoom icons in the browser toolbar.
	Pressing the + and - buttons on the device.
	Moving the right analogue stick up and down.


As well as making it easy to zoom in and out, Nintendo have done a few other things to improve the reading experience on the TV.

System font

One thing you’ll notice pretty quickly is that the browser lacks all the fonts we’re used to falling back to. Serif fonts are replaced with the system’s sans-serif font. I couldn’t get Typekit’s font loading method to work but Fontdeck, which works slightly differently, does display custom fonts.

 The system font has been optimised for reading at a distance and is easy to distinguish because the lowercase e has a quirky little tilt.

Don’t lose :focus

Using the D-pad to navigate is similar to using a keyboard. Individual links are focused on, with a blue outline drawn around them.

The recently redesigned An Event Apart site is an example that improves the experience for keyboard and D-pad users. They’ve added a yellow background colour to links on focus. It feels nicer than the default blue outline on its own.



Media

This year, television overtook PCs as the primary way to watch online video content. TV is the natural environment for video, and 42% of online TVs in the US are connected to the internet via a console. Unfortunately, the <video> tag isn’t supported in most console browsers, and those that have Flash installed often have such an old version that the video won’t play.

I suspect this has been a big driver in getting console browsers to support web standards. The Wii U is designed with video content in mind. It doesn’t support Flash but it does support the HTML5 <video> tag.

Some video formats can’t be played, but those that are supported bring up an optimised interface with a custom scrub bar. This is where the device switches from mirroring the TV to being a second screen. The full-screen video is displayed on the TV, and the interface on the gamepad.

The really clever bit is that while a video is playing, the gamepad user can keep the video playing on the TV screen while searching for another video or browsing the web. This is the same for images too.

On the left, the video is being shown full-screen on the TV and gamepad. Only the gamepad gets the scrub bar. Clicking the slide up/down button (circled) lets the gamepad user browse the web while the video on the TV continues to play full-screen, as shown in the image on the right.

There’s support for SVG images, and they look great on a high-definition TV screen. However, there’s currently no way to save or download files.

Preparing for console users

I wasn’t expecting to be quite as impressed as I am by this browser. It’s encouraging to see console makers investing time into improving the experience as well as the standards support. In the same way there was an explosion in mobile browser use as the experience got better, I’m sure we’ll see the same with console browsers as the experience improves.

The value of detection

Consoles offer a range of inputs including gesture, voice and controller buttons. That means we have to think about more diverse methods of input than just touch and click.

This is where I could tell you to add some detection methods such as user agent string sniffing to target a different experience for console users. But the majority of the time, that really isn’t necessary. TV console browsers are getting a lot better at compensating for the living room environment, and they’re designed to work with websites that haven’t been optimised for this context.

Rather than tighten our grip on optimising experiences for every device out there, we’ve got to be pragmatic. There are so many new devices coming out every week, our designs need to be future-proof rather than fixed to a particular device in time.

Even fuzzy device detection isn’t reliable – the PS Vita declares itself to be mobile, a mobile device and a Kindle Fire tablet, while the two DS devices state they’re neither mobile nor mobile phones nor tablets, but computers. They’re weird outliers, but they’re still important devices to consider.

Thinking broadly about how our designs will be interacted with and viewed on a TV screen can help improve that experience for everyone. This is about accessibility. Considering how someone uses a site with a D-pad, we can improve the experience for keyboard users. When we think about colour contrast and text legibility on TV screens, we can apply that for anyone who reads content on the web. So why just offer this to the TV users?

Playing with the browser


	…we want to prove to them through this Wii U Internet Browser that browsing itself can be an entertainment.
Iwata – Iwata Asks on Nintendo.com


Although I’m cautious about designing experiences for specific devices, it’s fun to experiment with the technology available. Nintendo have promised web developers access to the Wii U’s buttons and sensors. There’s already some JavaScript documentation, and a demo for you to try.

If you’re interested in making your own games, thanks to web standards, a lot of HTML5 games work already on the device. Matt Hackett wrote up his experience of testing the game he built, and he talks about some of features the browser lacks. There’s certainly an incentive there for console manufacturers to improve their HTML5 support so more games can be played in their browser.

What excites me about consoles is that it’s like looking at what might be available to us in future browsers. As well as thinking about how our sites work on small screens, we should also consider big screens. We’re already figuring out how images should work at different screen widths and connection speeds, but we’ve also got some interesting challenges ahead of us catering for second screen experiences and 3D-enabled devices. 

So, this Christmas, if you’re huddled round the game console or a smart TV, give the browser in it a try.",2012,Anna Debenham,annadebenham,2012-12-22T00:00:00+00:00,https://24ways.org/2012/unwrapping-the-wii-u-browser/,ux
88,"Think First, Code Later","This is a story that’s best told from the end, and it’s probably one you’re all familiar with.

You, or someone just like you, have been building a website, probably as part of a skilled and capable team. You’re a front-end developer, focusing on JavaScript – it’s either your sole responsibility or shared around. It’s quite a big job, been going on for months, and at last it feels like you’re reaching the end of it.

But, in a brief moment of downtime, you step back and take a look at the code as a whole. You notice that the folder called “jQuery plugins” suddenly looks rather full, and maybe there’s evidence of several methods of doing the same thing; there are loads of little niggly fixes in the bug tracker; and every place you use Ajax the structure of the data is slightly different. You sigh, and your shoulders droop slightly, and you think “Yeah, we’ll do that more cleanly next time.”

The thing is, you probably already know how to rewrite the start of this story to make the ending work better. This situation is not really anyone’s fault – it’s just an accumulation of all the things you decided along the way, all the things you agreed you’d fix later that have disappeared into the black hole of technical debt, and accomodating all the “can we just…?” requests from around the team and the client.

So, the solution to this is easy, right? More interminable planning meetings, more tightly controlled and documented specifications, less freedom to innovate, to try out new ideas and enjoy what you’re doing.

Wait, that sounds even less fun than the old way.

Minimum viable planning

Actually, planning and specifications are exactly what you need, but the way you go about them can make a real difference, both to the quality of your code, and the quality of your life as a developer. It can be as simple as being a little more thoughtful before starting on any new piece of functionality. Involve your whole team if possible, or at least those working on what you’re doing. Canvass opinions and work out what the solution to the problem might look like first, rather than coding speculatively to find out.

There are easy ways you can get into this habit of putting the thought and design up front, and it doesn’t have to mean spending more time on the project as a whole. It also doesn’t have to result in reams of functional specifications. Instead, let the code itself form the specification.

As JavaScript applications become more complex, unit testing is becoming ever more important. So embrace it, whether you prefer QUnit, or Mocha, or any of the other JavaScript testing frameworks out there. The TDD (or test-driven development) pattern is all about writing the tests first and then writing functional code to pass those tests; or, if you prefer, code that meets the specification given by the tests.

Sounds like a hassle at first, but once you get into the rhythm of it you should find that the time spent writing tests up front is no greater, and often significantly less, than the time you would have spent fixing bugs afterwards.

If what you’re working on requires an API between client and server (usually Ajax but this can apply to any method of sending or receiving data) then spend a bit of time with the back-end developer to design the data contracts, before either of you cut any code. Work out what the API endpoints are going to be, and what the data structure you’ll get back from a certain endpoint looks like. A mock JSON object documented on a wiki is enough and it can be atomic. Don’t worry about planning the entire project at once, just plan enough to get on with your current tasks.

Definition in this way doesn’t have to make your API immutable – change is still fine – but if you know roughly where you’re heading, then not only can your team’s efforts become more parallel, but you’re far more likely to have an easier time making it all work. And again, you have a specification – the shape of the data – to write your JavaScript against.

Putting everything together, you end up with a logical flow of development, from the specification agreed with the client (your backlog), to the specification agreed with your team (the API contract design), to the specification agreed with your code (your unit tests). Hopefully, there will be ample clues in all of this to inform your front-end library choices, because by then you should have a better picture of what you’re going to need.

What the framework?

As a JavaScript developer predominantly, these are the choices I’m particularly interested in – how and why you use JavaScript libraries and frameworks, both what you expect from them and what you actually get.

If we look back at how web development, and specifically JavaScript development has progressed – from the earliest days of using lines and lines of Dreamweaver code-barf to make an image rollover effect, to today’s large frameworks that handle working with the DOM, Ajax communication and visual effects all in one hit – the purpose of it is clear: to smooth over the inconsistent bumps between browsers and give a solid, reliable, predictable base on which to put our desired functionality.

Understanding what we expect the language as a specification to do, and matching that to what we observe browsers actually doing, and then smoothing out the differences, is a big job. Since the language and the implementations are also changing as we go along, it also feels like a never-ending job. So make full use of this valuable effort. Use jQuery or YUI or anything else you’re comfortable with, but it still pays to think early on about what you need your library to do and what the best choice is to meet that need.

I’ve come in to projects as a fixer and found, to take a recent example, that jQuery UI was being used just to provide a date picker and a modal effect. That’s a lot of code weight to provide two fairly simple pieces of functionality that could easily be covered by smaller plugins. Which isn’t to say that jQuery UI itself is a bad choice, but I could see that it had been included late on just to do those things, whereas a more considered approach would have been to put the library in early and use it more universally.

There are other choices, too. If you automatically throw in jQuery (or whatever your favourite main library is) to a small site with limited functionality, you might only touch a tiny fraction of its scope. In my own development I started looking at what I actually needed from a JavaScript library. For a simple project like What the Framework?, all jQuery needed to do was listen for .ready() and then perform some light DOM selection before handing over to a client-side MVC framework. So perhaps there was another way to go about this while still avoiding the cross-browser headaches.

Deleting jQuery

But the jQuery pattern is compelling and familiar. And once you’re comfortable with something, it’s a bit of an effort to force yourself out of that comfort zone and learn. But looking back at my whole career, I realised that I’ve relearned pretty much everything I do, probably several times, since I started out. So it’s worth keeping in mind that learning and trying new things is how development has advanced to where it is now, and how it will keep advancing in the future.

In the end this lead me to Ender, which is billed as an NPM-style package manager for the browser, letting you search for and manage small, loosely coupled modules and their dependencies, and compile them to one file with a common API.

For What the Framework I ended up with a set of DOM tools, Underscore and Knockout, all minified into 25kb of JavaScript. This compares really well with 32kb minified for jQuery on its own, and Ender’s use of the dollar variable and the jQuery-like syntax in many modules makes switching over a low-friction experience.

On more complex projects, where you’re really going to use all the features of something like jQuery, but want to minimise the loading of other dependencies when you don’t need them, I’ve recently started looking at Jam. This uses the RequireJS pattern to compile commonly used code into a library file and then manage dependencies and bring in others on a per-page basis depending on how you need it. Again, it all comes down to thinking about what you need and using it only when you need it. And the configurability of tools like Ender or Jam allow you to be responsive to changing requirements as your project grows.

There is no right answer

That’s not to say this way of working automatically makes things easier. It doesn’t. On a large, long-running project or one where future functionality is unknown, it’s still hard to predict and plan for everything – at least until crystal balls as a service come about. But by including strong engineering practices in your front-end, and trying to minimise technical debt, you’re at least giving yourself a decent safety net to guard against the “can we just…?” tendencies that are a fact of life.

So, really, this is not an advocation of using a particular technology or framework, because I can’t tell you what works for you or your team. But what I can tell you is that working this way round has done wonders for my productivity and enthusiasm, both for code quality and for trying out new libraries.

85,Starting Your Project on the Right Foot (and Keeping It There),"I’m not sure if anything is as terrifying as beginning a new design project. I often spend hours trying to find the best initial footing in a design, so I’ve been working hard to improve my process, particularly for the earliest stages of a project. I want to smooth out the bumps that disrupt my creative momentum and focus on the emotional highs and lows I experience, and then try to minimize the lows and ride the highs as long as possible. 

Design is often a struggle broken up by blissful moments of creative clarity that provide valuable force to move your work forward. Momentum is a powerful tool in creative work, and it’s something we don’t always maximize when we’re working because of the hectic nature of our field. Obviously, every designer is going to have a different process, but I thought I’d share some of the methods I’ve begun to adopt. I hope this will spark a conversation among designers who are interested in looking at process in a new way.

Jump-starting a project

I cannot overstate the importance of immersing yourself in design and collecting ample amounts of inspiration when beginning a project. I make it a daily practice to visit a handful of sites (Dribbble, Graphic Exchange, Web Creme, siteInspire, Designspiration, and others) and save any examples of design that I like. I then sort them into general categories (publication design, illustration, typography, web design, and so on). Enjoying a bit of fresh design every day helps me absorb it and analyze why it’s effective instead of just imitating it. 

Many designers are afraid to look at too much design for fear that they’ll be tempted to copy it, but I feel a steady influx of design inspiration reduces that possibility. You’re much more likely to take the easy way out and rip off a design if you’re scrambling for inspiration after getting stuck. If you are immersed in design from a variety of mediums, you’ll engage your creative brain on multiple levels and have an easier time creating something unique for your project. Looking at good design will not make you a good designer but it will make you a better designer.

Design is design

Try not to limit your visual research to the medium you’re working in. Websites, books, posters and packaging all have their own unique limitations and challenges, and any one of those characteristics could be useful to you. Posters need to grab the viewer and pass on a small tidbit of information; packaging needs to encourage physical interaction; and websites need to encourage exploration. If you know the challenges you’ll be facing, you will know where to look for design that tackles those same problems.

I find it refreshing to look at design from the turn of the nineteenth century, when type was laid out on objects without thought to aesthetics. Many vintage packages break all sorts of modern design rules, and looking at that kind of work is a great way to spark your creativity. Pulling yourself out of the box and away from the rules of what you’re working on can reveal solutions that are innovative and unique. After a little finessing, the warning label text from a 1940s hazardous chemical box from could have the exact type and icon arrangement you need for your project. There’s a massive pool of design to pull from that doesn’t have the limitations the web has, and exploring those design worlds will help you grow your own repertoire.

If all else fails, start with the footer

The very beginning of a project is the most frustrating point in a project for me. I’m trying to figure out typeface combinations, colors and the overall voice of the design, and until I find the right solutions, I’m a wreck. I’ve found often that my frustration stems from trying to solve too many problems at once. The beginning of a project has a lot of moving targets, nearly endless possible solutions, and constantly changing variables. You’ll knock out one problem only to discover your solution doesn’t jive with something you worked out earlier — you end up designing in circles.

If you find yourself getting stuck at the beginning of a website design, try working out one specific element of the site and see what emerges. I’m going to recommend the footer. Why? Footers can easily be ignored in a design or become a dumping ground for items that couldn’t be worked into the main layout. But, at the start of most projects, the minimum content requirements for the footer are usually established. There needs to be a certain number of links, social media buttons, copyright details, a search bar, and so on. It’s a self-contained item within the design that has a specific purpose, and that’s a great element to focus on when you’re stuck in a design. Colors, typefaces, link styles, input fields and buttons can all be sketched out from just the footer. It’s a very flexible element that can be as prominent or subtle as you want, and it’s a solid starting point for setting the tone and style of a site.

Save the details

Designers love details. I love details. But don’t let nitpicking early on in your process kill your creative momentum. Design is an emotional process, and being frustrated or defeated by a tricky problem or a graphical detail you just can’t nail down can deflate your creative energies. If you hit a roadblock, set it aside and tackle another piece of the project. As you spend time engaged in a design, the style you develop will evolve according to the needs of the content, and you might arrive naturally at a solution that will work perfectly for the problem that had you stuck before. 

If I find myself working on one particular element for more than a half an hour without any clear movement, I shelve it. Designers often wear their obsessive detail-oriented tendencies as a badge of honor, but there’s a difference between making the design better and wasting time. If you’ve spent hours nudging elements around pixel by pixel and can’t settle on something, it probably means what you’re doing isn’t making a huge improvement on the design. Don’t be afraid to let it lie and come at it again with fresh eyes. You will be better equipped to tackle the finer points of a project once you’ve got the broad strokes defined.

Have a plan when you start and stop designing

We all know that creativity isn’t something you can turn on effortlessly, and it’s easy to forget the emotional process that goes along with design. If you leave a project in a place of frustration, it’s going to stay with you in your free time and affect you negatively, like a dark cloud of impending disaster. Try to end each design session with a victory, a small bit of definable progress that you can take with you in your downtime. Even something as small as finding the right opacity for the interior shadow on the search bar in the header of the site is a win. Likewise, when you return to a project after a break, it can be difficult to get the ball rolling on the design again if you set it down without a clear path for the next steps. I find that I work on details best when I’m returning from downtime, when I’m fresh and re-energized and ready to dig in again. Try to pick out at least one element you’d like to fine-tune when you are winding down in a design session and use it to kick-start your next session.

Content is king

I would argue there is nothing more crucial to the success of a design than having the content defined from the outset. Designing without content is similar to designing without an audience, and designing with vague ideas of content types and character limits is going to result in a muted design that doesn’t reach its full potential. Images and language go hand in hand with design, and can take a design from functional to outstanding if you have them available from the outset. We don’t always have the luxury of having content to build a design around, but fight for it whenever you can. For example, if the site you are designing is full of technical jargon, your paragraphs might need a longer line length to accommodate the longer words being used. 

Often, working with content will lead to design solutions you wouldn’t have come to otherwise. Design speaks to content, and content speaks to design. Lorem ipsum doesn’t speak to anyone (unless you know Latin, in which case, congratulations!).

Every project has its own set of needs, and every designer has his or her own method of working. There’s obviously no perfect process to design, and being dogmatic about process can be just as harmful as not having one. Exposing yourself to new design and new ways of designing is an easy way to test your skills and grow. When things are hard and you can’t get any momentum going on a design, this is when your skill set is truly challenged. We all hope to get wonderful projects with great assets and ample creative possibilities, but you won’t always be so blessed, and this is when the quality of your process is really going to shine.",2012,Bethany Heck,bethanyheck,2012-12-02T00:00:00+00:00,https://24ways.org/2012/starting-your-project-on-the-right-foot/,process
74,Should We Be Reactive?,"Evolution

Looking at the evolution of the web and the devices we use should help remind us that the times we’re adjusting to are just another step on a journey. These times seem to be telling us that we need to embrace flexibility.

Imagine an HTML file containing nothing but text. It’s viewable on any web-capable device and reasonably readable: the notion of the universality of the web was very much a founding principle. Right from the beginning, browser vendors understood that we’d want text to reflow (why wouldn’t we?), so I consider the first websites to have been fluid. 

As we attempted to exert more control through our designs in the early days of the web, debates about whether we should produce fixed or fluid sites raged. We could create fluid designs using tables, but what we didn’t have then was a wide range of web capable devices or the ability to control this fluidity. The biggest changes occurred when stats showed enough people using a different screen resolution we could cater for.

To me, the techniques of responsive web design provide the control we were missing. Combining new approaches to layout and images with media queries empowered us to learn how to embrace the inherent flexibility of the web in ways to suit our work and the devices used by our audience.

Perhaps another kind of flexibility might be found in how we use context to affect how we present our content; to consider how we might use the information we can access from people, browsers and devices to provide web experiences – effectively creating sites that react to initial or changing circumstances in the relationship between people and our content.

Embracing flexibility

So what is context? Put simply, you could think of it as a secondary piece of information that helps clarify the meaning of the first. It helps set a scene or describe circumstances. I think that Cennydd Bowles has summed it up really well through talks he’s given recently, in which he’s arrived at the acronym DETAILS (Device, Environment, Time, Activity, Individual, Location, Social) – I encourage you to keep an eye out for his next book due in the new year where he’ll explore this idea much further. This clarity over what context could mean in terms of what we do on the web is fundamental, directing us towards ways we might use it.

When you stop to think about it, we’ve been using some basic pieces of this information right from the beginning, like bits of JavaScript or Java applets that serve an appropriate greeting to your site’s visitors, or show their location, or even local weather. But what if we think of this from the beginning of our projects?

We should think about our content first. Once we know this and have a direction, perhaps then we can think about what context, or even multiple contexts, might help us to communicate more effectively.

The real world

There’s always been a disconnect between the real world and the web, which is to be expected. But the world around us is a sea of data; every fundamental building block: people, places, events and things have information waiting to be explored. 

For sites based around physical objects or locations, this divide is really apparent. We don’t ordinarily take the time to describe in code the properties of a place, or consider whether your relationship to the place in the real world should have any impact on your relationship with a site about it.

When I think about local businesses, they have such rich properties to draw on and yet we don’t really explore them in any meaningful way, even through something as simple as opening hours.

Now we have data…

We’ve long had access to the current time both on server- and client-sides. The use of geolocation is easier than ever, but when we look at the range of information we could glean to help us make some choices, maybe there’s some help on the horizon from projects like the W3C Device APIs Working Group. This might prove useful to help make us aware of network and battery conditions of a device, along with the potential to gain data from other sensors, which could tell us about lighting conditions, ambient noise levels and temperature depending on the capabilities of the device.

It may be that our sites have some form of login or access to your profile from another site. Along with data from our devices and browsers, this should give us a sense of how best to talk to our audience in certain situations. We don’t necessarily need to know any personal details, just enough to make decisions about how to present our sites.

The reactive web?

So why reactive web design? I’m hoping that a name might help us to have a common vocabulary not only about what we mean when we talk about context, but how it could be considered through our projects, right from the early stages. How could this manifest itself?

A simple example might be a location-aware panel on your site. Perhaps the space is a little down in your content hierarchy but serves a perfectly valid purpose by default. To visitors outside the country perhaps this works fine, but within your country maybe this panel could be used to communicate more effectively. Further still, if we knew the visitors were in the vicinity, we could talk to them more directly. 

What if both time and location were relevant? This space could work as before but you could consider how time could intersect with your local audience. If you know they’re local and it’s a certain time of day, you could communicate directly with them.

This example isn’t beyond what banner ads often do and uses easily accessible information. There are more unusual combinations we may be able to find, such as movement and presence. Perhaps a site that tells a story, which changes design and content based on whether you’re moving, how long you’ve been on the site and how far you’ve travelled. This isn’t what we typically expect from websites, but we should bear in mind that what websites are now will not be what they become in the future.

You could do much of this contextual presentation through native apps, of course. The Silent History, an app novel written and designed for iPad and iPhone, uses an exploration element, providing “hundreds of location-based stories across the U.S. and around the world. These can be read only when your device’s GPS matches the coordinates of the specified location.” But considering the universality of the web, we could redefine what web-based experiences should be like. Not all methods would work well on the web, but that’s a decision that has to be made for a specific project.

By thinking more broadly about any web-capable device, we can use what we know to provide relevant experiences for our site’s visitors. We need to be sure what we mean by relevant, of course!

Reality bites

While there are incredible possibilities, from a simple panel on a site to something bordering on living sites that evolve and change with our circumstances, we need to act with a degree of pragmatism and understand how much of what we could do is based on assumptions and the bias of our own experiences.

We could go wild with changing the way our content is presented based on contextual information, but if we’re not careful what we end up with confuses and could provide a very fractured experience. As much as possible we need to think more ethnographically, observe and question people in the situations we think may be relevant, and test our assumptions as early as we can. Even on small projects, there may be ways we can validate our assumptions and test with our audience. The key to applying contextual content or cues is not to break the experience between contextual views (as I think we now wouldn’t when hiding content on a mobile view). 

It’s another instance of progressive enhancement – as we know certain pieces of information, we can enhance the experience. Also, if you do change content, how can you not make a more cumbersome experience for your visitors?

It’s all about communication

Content is at the core of what we do, but if we consider context we need to understand the impact on that. The effect could be as subtle as an altered hierarchy, involve swapping out panels of content, or in extreme instances perhaps all of your content might change. In some ways, this extends the notion of adaptive content that Karen McGrane has been talking about, to how we write and store the content we create. Thinking about the the impact of context may require us to re-evaluate our site structure, too. Whatever we decide, we have to be clear what will happen and manage the expectations of our users.

The bottom line

What I’m proposing isn’t that we go crazy and end up with a confused, disjointed set of experiences across the web. What I hope is that starting right from the beginning of a project, we think about what context is and could be, and see what relevance it might have to what we’re trying to communicate. This strategic process leads us to think about design.

We are slowly adapting to what it means to be flexible through responsive and adaptive processes. What does thinking about contextual states mean to us (or designing for state in general)? Does this highlight again how difficult it’ll be for our tools to keep up with our processes and output?

In terms of code, the vast majority of this data comes from the client-side through JavaScript. While we can progressively enhance, this could lead to a lot of code bloat through feature or capability detection, and potentially a lot of conditional loading of scripts. It’s a real shame we don’t get much we can rely on from the server-side – we know how unreliable user agents are!

We need to understand why we’d do this. Are we trying to communicate well and be useful, or doing it to show off? Underneath it all, what do we base our decisions on? Do we have actual insight or are we proceeding from our assumptions and the bias of our own experiences? Scott Jenson summed it up best for me: (to paraphrase) the pain we put people through has to be greatly outweighed by the value we offer.

I see that this could be another potential step in our evolution on the web; continuing this exploration of the flexibility the web allows us. It’s amazing we can do such incredible things from what is essentially a set of disparate, linked documents.",2012,Dan Donald,dandonald,2012-12-09T00:00:00+00:00,https://24ways.org/2012/should-we-be-reactive/,design
81,Science!,"Sometimes we want to capture people’s attention at a glance to communicate something fast. At other times we want to have the interface fade away into the background, letting people paint pictures in their minds with our words (if you’ll forgive a little flowery festive flourish).

I tend to distinguish between these two broad objectives as designing for impact on the one hand, and designing for immersion on the other. What defines them is interruption. Impact needs an attention-grabbing interruption. Immersion requires us to remove interruption from the interface. Careful design deliberately interrupts but doesn’t accidentally disrupt. If that seems to make sense to you, then you’ll find the following snippets of science as useful as I did.

Saccades and fixations

As you’re reading this your eyes are skipping along the lines in tiny jumps. During each jump everything is blurred. Each jump ends in a small pause so your brain can take a snapshot of the letters. It arranges them into words, and then parses out the meaning — fast — in around a quarter of a second.

The jumps are called saccades. The pauses are called fixations. Sometimes we take regressive saccades, skipping back to reread. There’s a simple example in the excellent little book, Detail in Typography, by Jost Hochuli.



If you want to explore the science of reading in much more depth, I recommend the excellent paper, “The Science of Word Recognition”, by Dr Kevin Larson of Microsoft.

To design for legibility and readability is to design for saccades and fixations. It’s the craft of making it easy for people’s brains to extract meaning, using techniques like good contrast, font size, spacing and structure, and only interrupting the reading experience deliberately.

Scan paths

At some point when visiting 24 ways you probably scanned the screen to get orientated. The journey your eyes took is known as a scan path. Scan paths are made up of saccades and fixations. Right now you’re following a scan path as you read, along one line, and down to the next. This is a map of the scan paths found by Olivier Le Meur from observing people looking at Rembrandt’s Leçon d’anatomie:



For websites, the scan path is a little different. This is an aggregate scan path of Google from LC Technologies:



The average shape of a website scan path becomes clearer in this average scan path taken by forty-six people during research by the Poynter Institute, the Estlow Center for Journalism & New Media, and Eyetools:



Just like when we read text arranged left to right in a vertical column, scan paths follow a roughly Z-shaped pattern from the top left to bottom right. Sometimes we skip back to reread a word or sentence, or glance again at a specific element, but the Z-shaped scan path persists.

Designing for scan paths is to organise content to help people move through an interface to get orientated, and to read.

The elements that are important enough to need impact must interrupt the scan path and clearly call attention to themselves. However, they don’t always need to clip people round the ear from multiple directions at once to get attention. It helps to list elements by importance. That gives us an interruption hierarchy to work with. Elements can then interrupt the design with degrees of contrast to the rest of the content using either positioning, treatment, or both. Ta-da! Impact achieved, but gently. No clips round the ear required.

Swinging mood

Human beings are resilient. Among the immersion and occasional interruptions, we even like a little disruption, especially if it’s absurd and funny. The Ling’s Cars website proves it. In fact, we’re so resilient that we can work around all kinds of mayhem to get a seemingly simple task done.

In one study, “The Aesthetics of Reading” (PDF, 480Kb), Dr Kevin Larson of Microsoft and Dr Rosalind Picard of MIT explored the effect of good typography on mood. Two versions of the New Yorker ePeriodical were created. One was typeset well and the other poorly.



They engaged twenty volunteers — half male, half female — and showed the good version to half of the participants. The other half saw the poor version.

The good doctors found that, “there are important differences between good and poor typography that appear to have little effect on common performance measures such as reading speed and comprehension.” In short, good typography didn’t help people read faster or comprehend better.

Oh. On the face of it that seems to invalidate what we designers do. Hold your horses, though! They also found that “the participants who received the good typography performed better on relative subjective duration and on certain cognitive tasks”, and that “good typography induces a good mood.”

This means that even though there were no actual differences in reading speed and comprehension, the people who read the version with good typography thought that it took less time to read, and were induced into a good mood by doing so. Not only that, but by being in a good mood, people were more capable of completing creative tasks faster.

That was a revelation to me. It means that the study showed there is a positive, measurable, emotional and perceptual benefit to good typography and design. To paraphrase: time and tasks fly when you’re having fun!

So, among all my talk of saccades, fixations, scan paths and typesetting, there is science, and the science helps us qualify our design decisions when we need to, and do our jobs better. The science helps us understand how people will interact with our work, and what the actual benefits are for them, and the products or organisations we serve. Good design equals a subjectively quicker experience, a good mood, objectively faster completion of tasks, and happiness for everyone.

84,Responsive Responsive Design,"Now more than ever, we’re designing work meant to be viewed along a gradient of different experiences. Responsive web design offers us a way forward, finally allowing us to “design for the ebb and flow of things.”


With those two sentences, Ethan closed the article that introduced the web to responsive design. Since then, responsive design has taken the web by storm. Seemingly every day, some company is touting their new responsive redesign. Large brands such as Microsoft, Time and Disney are getting in on the action, blowing away the once common criticism that responsive design was a technique only fit for small blogs.

Certainly, this is a good thing. As Ethan and John Allsopp before him, were right to point out, the inherent flexibility of the web is a feature, not a bug. The web’s unique ability to be consumed and interacted with on any number of devices, with any number of input methods is something to be embraced.

But there’s one part of the web’s inherent flexibility that seems to be increasingly overlooked: the ability for the web to be interacted with on any number of networks, with a gradient of  bandwidth constraints and latency costs, on devices with varying degrees of hardware power.

A few months back, Stephanie Rieger tweeted


	“Shoot me now…responsive design has seemingly become confused with an opportunity to reduce performance rather than improve it.”


I would love to disagree, but unfortunately the evidence is damning. Consider the size and number of requests for four highly touted responsive sites that were launched this year:


	74 requests, 1,511kb
	114 requests, 1,200kb
	99 requests, 1,298kb
	105 requests, 5,942kb


And those numbers were for the small screen versions of each site!

These sites were praised for their visual design and responsive nature, and rightfully so. They’re very easy on the eyes and a lot of thought went into their appearance. But the numbers above tell an inconvenient truth: for all the time spent ensuring the visual design was airtight, seemingly very little (if any) attention was given to their performance.

It would be one thing if these were the exceptions, but unfortunately they’re not. Guy Podjarny, who has done a lot of research around responsive performance, discovered that 86% of the responsive sites he tested were either the same size or larger on the small screen as they were on the desktop.

The reality is that high performance should be a requirement on any web project, not an afterthought. Poor performance has been tied to a decrease in revenue, traffic, conversions, and overall user satisfaction. Case study after case study shows that improving performance, even marginally, will impact the bottom line. The situation is no different on mobile where 71% of people say they expect sites to load as quickly or faster on their phone when compared to the desktop.

The bottom line: performance is a fundamental component of the user experience.

So, given it’s extreme importance in the success of any web project, why is it that we’re seeing so many bloated responsive sites?

First, I adamantly disagree with the belief that poor performance is inherent to responsive design. That’s not a rule – it’s a cop-out. It’s an example of blaming the technique when we should be blaming the implementation. This argument also falls flat because it ignores the fact that the trend of fat sites is increasing on the web in general. While some responsive sites are the worst offenders, it’s hardly an issue resigned to one technique.

To fix the issue, we need to stop making excuses and start making improvements instead. Here, then, are some things we can do to start improving the state of responsive performance, and performance in general, right now.

Create a culture of performance

If you understand just how important performance is to the success of a project, the natural next step is to start creating a culture where high performance is a key consideration. 

One of the things you can do is set a baseline. Determine the maximum size and number of requests you are going to allow, and don’t let a page go live if either of those numbers is exceeded. The BBC does this with its responsive mobile site.

A variation of that, which Steve Souders discussed in a recent podcast is to create a performance budget based on those numbers. Once you have that baseline set, if someone comes along and wants to add a something to the page, they have to make sure the page remains under budget. If it exceeds the budget, you have three options:


	Optimize an existing feature or asset on the page
	Remove an existing feature or asset from the page
	Don’t add the new feature or asset


The idea here is that you make performance part of the process instead of something that may or may not get tacked on at the end.

Embrace the pain

This troubling trend of web bloat can be blamed in part on the lack of pain associated with poor performance. Most of us work on high-speed connections with low latency. When we fire up a 4Mb site, it doesn’t feel so bad. 

When I tested the previously mentioned 5,942kb site on a 3G network, it took over 93 seconds to load. A minute and a half just staring at a white screen. Had anyone working on that project experienced that, you can bet the site wouldn’t have launched in that state.

Don’t just crunch numbers. Fire up your site on a slower network and see what it feels like to wait. If you don’t have access to a slow network, simulate one using a tool like Slowy, Throttle or the Network Conditioner found in Mac OS X 10.7.

Watch for low-hanging fruit

There are a bunch of general performance improvements that apply to any site (responsive or not) but often aren’t made. A great starting point is to refer to Yahoo!‘s list of rules.

Some of this might sound complicated or intimidating, but it doesn’t have to be. You can grab an .htaccess file from HTML 5 Boilerplate or use Sergey Chernyshev’s drop-in .htaccess file. You can use tools like SpriteMe to simplify the creation of sprites, and ImageOptim to compress images.

Just by implementing these simple optimizations you will achieve a noticeable improvement in terms of weight and page load time.

Be careful with images

The most common offender for poor responsive performance is downloading unnecessarily large images, or worse yet, multiple sizes of the same image. 

For background images, simply being careful with where and how you include the image can ensure you don’t get caught in the trap of multiple background images being downloaded without being used. Don’t count on display:none to help. While it may hide elements from displaying on screen, those images will still be requested and downloaded.

Content images can be a little trickier. Whatever you do, don’t serve a large image that works on a large screen display to small screens. It’s wasteful, not only in terms of adding weight to the page, but also in wasting precious memory. Instead, use a tool like Adaptive Images or src.sencha.io to make sure only appropriately sized images are being downloaded. 

The new <picture> element that has been so often discussed is another excellent solution if you’re feeling particularly future-oriented. A picture polyfill exists so that you can start using the element now without any worries about support.

Conditional loading

Don’t load any more than you absolutely need to. If a script isn’t needed at certain sizes, use the matchMedia polyfill to ensure it only loads when needed. Use eCSSential to do the same for unnecessary CSS files.

Last year on 24 ways, Jeremy Keith wrote an article about conditional loading of content in a responsive design based on the screen width. The technique was later refined by the Filament Group into what they dubbed the Ajax-Include Pattern. It’s a powerful and simple way to lighten the load on small screens as well as reduce clutter.

Go vanilla?

If you take a look at the HTTP Archive you’ll see that other than image size, JavaScript is the heaviest asset on a page weighing in at 215kb on average. It also boasts the fifth highest correlation to load time as well as the second highest correlation to render time. 

Much of the weight can be attributed to our industry’s increasing reliance on frameworks. This is especially a concern on mobile devices. PPK recently exclaimed that current JavaScript libraries are just “too heavy for mobile”. “Research from Stoyan Stefanov on parse times supports this. On some Android and iOS devices, it can take as long as 200-300ms just to parse jQuery.

There’s nothing wrong about using a framework, but the problem is that they’ve become the default. Before dropping another framework or plugin into a page, we should stop to consider the value it adds and whether we could accomplish what we need to do using a combination of vanilla JavaScript and CSS instead. (This is a great example of a scenario where a performance budget could help.)

Start thinking beyond visual aesthetics

We love to tout the web’s universality when discussing the need for responsive design. But that universality is not limited simply to screen size. Networks and hardware capabilities must factor in as well.

The web is an incredibly dynamic and interactive medium, and designing for it demands that we consider more than just visual aesthetics. Let’s not forget to give those other qualities the attention they deserve.",2012,Tim Kadlec,timkadlec,2012-12-05T00:00:00+00:00,https://24ways.org/2012/responsive-responsive-design/,design
79,Responsive Images: What We Thought We Needed,"If you were to read a web designer’s Christmas wish list, it would likely include a solution for displaying images responsively. For those concerned about users downloading unnecessary image data, or serving images that look blurry on high resolution displays, finding a solution has become a frustrating quest.

Having experimented with complex and sometimes devilish hacks, consensus is forming around defining new standards that could solve this problem. Two approaches have emerged.

The <picture> element markup pattern was proposed by Mat Marquis and is now being developed by the Responsive Images Community Group. By providing a means of declaring multiple sources, authors could use media queries to control which version of an image is displayed and under what conditions:

<picture width=""500"" height=""500"">
  <source media=""(min-width: 45em)"" src=""large.jpg"">
  <source media=""(min-width: 18em)"" src=""med.jpg"">
  <source src=""small.jpg"">
  <img src=""small.jpg"" alt="""">
  <p>Accessible text</p>
</picture>

A second proposal put forward by Apple, the srcset attribute, uses a more concise syntax intended for use with the <img> element, although it could be compatible with the <picture> element too. This would allow authors to provide a set of images, but with the decision on which to use left to the browser:

<img src=""fallback.jpg"" alt="""" srcset=""small.jpg 640w 1x, small-hd.jpg 640w 2x, med.jpg 1x, med-hd.jpg 2x "">

Enter Scrooge


	Men’s courses will foreshadow certain ends, to which, if persevered in, they must lead.
Ebenezer Scrooge


Given the complexity of this issue, there’s a heated debate about which is the best option. Yet code belies a certain truth. That both feature verbose and opaque syntax, I’m not sure either should find its way into the browser – especially as alternative approaches have yet to be fully explored.

So, as if to dampen the festive cheer, here are five reasons why I believe both proposals are largely redundant.

1. We need better formats, not more markup

As we move away from designs defined with fixed pixel values, bitmap images look increasingly unsuitable. While simple images and iconography can use scalable vector formats like SVG, for detailed photographic imagery, raster formats like GIF, PNG and JPEG remain the only suitable option.

There is scope within current formats to account for varying bandwidth but this requires cooperation from browser vendors. Newer formats like JPEG2000 and WebP generate higher quality images with smaller file sizes, but aren’t widely supported.

While it’s tempting to try to solve this issue by inventing new markup, the crux of it remains at the file level.

Daan Jobsis’s experimentation with image compression strengthens this argument. He discovered that by increasing the dimensions of a JPEG image while simultaneously reducing its quality, a smaller files could be produced, with the resulting image looking just as good on both standard and high-resolution displays.

This may be a hack in lieu of a more permanent solution, but it’s applied in the right place. Easy to accomplish with existing tools and without compatibility issues, it has few downsides. Further experimentation in this area should be encouraged, with standardisation efforts more helpful if focused on developing new image formats or, preferably, extending existing ones.

2. Art direction doesn’t belong in markup

A desired benefit of the <picture> markup pattern is to allow for greater art direction. For example, rather than scaling down images on smaller displays to the point that their content is hard to discern, we could present closer crops instead:



This can be achieved with CSS of course, although with a download penalty for those parts of an image not shown. This point may be negligible, however, since in the context of adaptable layouts, these hidden areas may end up being revealed anyway.

Art direction concerns design, not content. If we wish to maintain a separation of concerns, including presentation within our markup seems misguided.

3. The size of a display has little relation to the size of an image

By using media queries, the <picture> element allows authors to choose which characteristics of the screen or viewport to query for different images to be displayed.

In developing sites at Clearleft, we have noticed that the viewport is essentially arbitrary, with the size of an image’s containing element more important. For example, look at how this grid of images may adapt at different viewport widths:



As we build more modular systems, components need to be adaptable in and of themselves. There is a case to be made for developing more contextual methods of querying, rather than those based on attributes of the display.

4. We haven’t lived with the problem long enough

A key strength of the web is that the underlying platform can be continually iterated. This can also be problematic if snap judgements are made about what constitutes an improvement.

The early history of the web is littered with such examples, be it the perceived need for blinking text or inline typographic styling. To build a platform for the future, additions to it should be carefully considered. And if we want more consistent support across browsers, burdening vendors with an ever increasing list of features seems counterproductive.

Only once the need for a new feature is sufficiently proven, should we look to standardise it. Before we could declare hover effects, rounded corners and typographic styling in CSS, we used JavaScript as a polyfill. Sure, doing so was painful, but use cases were fully explored, and the CSS specification better reflected the needs of authors.

5. Images and the web aesthetic

The srcset proposal has emerged from a company that markets its phones as being able to browse the real – yet squashed down, tapped and zoomable – web. Perhaps Apple should make its own website responsive before suggesting how the rest of us should do so.

Converserly, while the <picture> proposal has the backing of a few respected developers and designers, it was born out of the work Mat Marquis and Filament Group did for the Boston Globe. As the first large-scale responsive design, this was a landmark project that ignited the responsive web design movement and proved its worth. But it was the first.

Its design shares a vernacular to that of contemporary newspaper websites, with a columnar, image-laden and densely packed layout. Compared to more recent examples – Quartz, The Next Web and the New York Times Skimmer – it feels out of step with the future direction of news sites. In seeking out a truer aesthetic for the web in which software interfaces have greater influence, we might discover that the need for responsive images isn’t as great as originally thought.



Building for the future

With responsive design, we’ve accepted the idea that a fully fluid layout, rather than a set of fixed layouts, is best suited to the web’s unpredictable nature. Current responsive image proposals are antithetical to this approach.

We need solutions that lack complexity, are device-agnostic and work within existing workflows. Any proposal that requires different versions of the same image to be created, is likely to have to acquiesce under the pressure of reality.

While it’s easy to get distracted about the size and quality of an image, and how we might choose to serve it, often the simplest solution is not to include it at all. After years of gluttonous design practice, in which fast connections and expansive display sizes were an accepted norm, we have got use to filling pages with needless images and countless items of page furniture.

To design more adaptable experiences, the presence of every element needs to be questioned, for its existence requires additional data to be downloaded or futher complexity within a design system. Conditional loading techniques mean that the inclusion of images is no longer a binary choice, but can instead appear in a progressively enhanced manner.

So here is my proposal. Instead of spending the next year worrying about responsive images, let’s embrace the constraints of the medium, and seek out new solutions that can work within them.",2012,Paul Lloyd,paulrobertlloyd,2012-12-11T00:00:00+00:00,https://24ways.org/2012/responsive-images-what-we-thought-we-needed/,code
92,Redesigning the Media Query,"Responsive web design is showing us that designing content is more important than designing containers. But if you’ve given RWD a serious try, you know that shifting your focus from the container is surprisingly hard to do. There are many factors and
instincts working against you, and one culprit is a perpetrator you’d least suspect.

The media query is the ringmaster of responsive design. It lets us establish the rules of the game and gives us what we need most: control. However, like some kind of evil double agent, the media query is actually working against you.

Its very nature diverts your attention away from content and forces you to focus on the container.

The very act of choosing a media query value means choosing a screen size.

Look at the history of the media query—it’s always been about the container. Values like screen, print, handheld and tv don’t have anything to do with content. The modern media query lets us choose screen dimensions, which is great because it makes RWD possible. But it’s still the act of choosing something that is completely unpredictable.

Content should dictate our breakpoints, not the container. In order to get our focus back to the only thing that matters, we need a reengineered media query—one that frees us from thinking about screen dimensions. A media query that works for your content, not the window. Fortunately, Sass 3.2 is ready and willing to take on this challenge.

Thinking in Columns

Fluid grids never clicked for me. I feel so disoriented and confused by their squishiness. Responsive design demands their use though, right?

I was ready to surrender until I found a grid that turned my world upright again. The Frameless Grid by Joni Korpi demonstrates that column and gutter sizes can stay fixed. As the screen size changes, you simply add or remove columns to accommodate. This made sense to me and armed with this concept I was able to give Sass the first component it needs to rewrite the media query: fixed column and gutter size variables.

$grid-column: 60px;
$grid-gutter: 20px;

We’re going to want some resolution independence too, so let’s create a function that converts those nasty pixel values into ems.

@function em($px, $base: $base-font-size) {
	@return ($px / $base) * 1em;
}

We now have the components needed to figure out the width of multiple columns in ems. Let’s put them together in a function that will take any number of columns and return the fixed width value of their size.

@function fixed($col) {
	@return $col * em($grid-column + $grid-gutter)
}

With the math in place we can now write a mixin that takes a column count as a parameter, then generates the perfect media query necessary to fit that number of columns on the screen. We can also build in some left and right margin for our layout by adding an additional gutter value (remembering that we already have one gutter built into our fixed function).

@mixin breakpoint($min) {
	@media (min-width: fixed($min) + em($grid-gutter)) {
		@content
	}
}

And, just like that, we’ve rewritten the media query. Instead of picking a minimum screen size for our layout, we can simply determine the number of columns needed. Let’s add a wrapper class so that we can center our content on the screen.

@mixin breakpoint($min) {
    @media (min-width: fixed($min) + em($grid-gutter)) {
	.wrapper {
		width: fixed($min) - em($grid-gutter);
		margin-left: auto; margin-right: auto;
	}
	@content
    }
}

Designing content with a column count gives us nice, easy, whole numbers to work with. Sizing content, sidebars or widgets is now as simple as specifying a single-digit number.

@include breakpoint(8) {
	.main { width: fixed(5); }
	.sidebar { width: fixed(3); }
}

Those four lines of Sass just created a responsive layout for us. When the screen is big enough to fit eight columns, it will trigger a fixed width layout. And give widths to our main content and sidebar. The following is the outputted CSS…

@media (min-width: 41.25em) {
  .wrapper {
    width: 38.75em;
    margin-left: auto; margin-right: auto;
  }
  .main { width: 25em; }
  .sidebar { width: 15em; }
}

Demo

I’ve created a Codepen demo that demonstrates what we’ve covered so far. I’ve added to the demo some grid classes based on Griddle by Nicolas Gallagher to create a floatless layout. I’ve also added a CSS gradient overlay to help you visualize columns. Try changing the column variable sizes or the breakpoint includes to see how the layout reacts to different screen sizes.

Responsive Images

Responsive images are a serious problem, but I’m excited to see the community talk so passionately about a solution. Now, there are some excellent stopgaps while we wait for something official, but these solutions require you to mirror your breakpoints in JavaScript or HTML. This poses a serious problem for my Sass-generated media queries, because I have no idea what the real values of my breakpoints are anymore. For responsive images to work, JavaScript needs to recognize which media query is active so that proper images can be loaded for that layout.

What I need is a way to label my breakpoints. Fortunately, people much smarter than I have figured this out. Jeremy Keith devised a labeling method by using CSS-generated content as the storage method for breakpoint labels. We can use this technique in our breakpoint mixin by passing a label as another argument.

@include breakpoint(8, 'desktop') { /* styles */ }

Sass can take that label and use it when writing the corresponding media query. We just need to slightly modify our breakpoint mixin.

@mixin breakpoint($min, $label) {
    @media (min-width: fixed($min) + em($grid-gutter)) {

        // label our mq with CSS generated content
	body::before { content: $label; display: none; }

	.wrapper {
		width: fixed($min) - em($grid-gutter);
		margin-left: auto; margin-right: auto;
	}
	@content
    }
}

This allows us to label our breakpoints with a user-friendly string. Now that our media queries are defined and labeled, we just need JavaScript to step in and read which label is active.

// get css generated label for active media query
var label = getComputedStyle(document.body, '::before')['content'];

JavaScript now knows which layout is active by reading the label in the current media query—we just need to match that label to an image. I prefer to store references to different image sizes as data attributes on my image tag.

<img class=""responsive-image"" data-mobile=""mobile.jpg"" data-desktop=""desktop.jpg"" />
<noscript><img src=""desktop.jpg"" /></noscript>

These data attributes have names that match the labels set in my CSS. So while there is some duplication going on, setting a keyword like ‘tablet’ in two places is much easier than hardcoding media query values. With matching labels in CSS and HTML our script can marry the two and load the right sized image for our layout.

// get css generated label for active media query
var label = getComputedStyle(document.body, '::before')['content'];

// select image
var $image = $('.responsive-image');

// create source from data attribute
$image.attr('src', $image.data(label));

Demo

With some slight additions to our previous Codepen demo you can see this responsive image technique in action. While the above JavaScript will work it is not nearly robust enough for production so the demo uses a jQuery plugin that can accomodate multiple images, reloading on screen resize and fallbacks if something doesn’t match up.

Creating a Framework

This media query mixin and responsive image JavaScript are the center piece of a front end framework I use to develop websites. It’s a fluid, mobile first foundation that uses the breakpoint mixin to structure fixed width layouts for tablet and desktop. Significant effort was focused on making this framework completely cross-browser. For example, one of the problems with using media queries is that essential desktop structure code ends up being hidden from legacy Internet Explorer. Respond.js is an excellent polyfill, but if you’re comfortable serving a single desktop layout to older IE, we don’t need JavaScript. We simply need to capture layout code outside of a media query and sandbox it under an IE only class name.

// set IE fallback layout to 8 columns
$ie-support = 8;

// inside of our breakpoint mixin (but outside the media query)
@if ($ie-support and $min <= $ie-support) {
	.lt-ie9 { @content; }
}

Perspective Regained

Thinking in columns means you are thinking about content layout. How big of a screen do you need for 12 columns? Who cares? Having Sass write media queries means you can use intuitive numbers for content layout. A fixed grid means more layout control and less edge cases to test than a fluid grid. Using CSS labels for activating responsive images means you don’t have to duplicate breakpoints across separations of concern. 

It’s a harmonious blend of approaches that gives us something we need—responsive design that feels intuitive. And design that, from the very outset, focuses on what matters most. Just like our kindergarten teachers taught us: It’s what’s inside that counts.",2012,Les James,lesjames,2012-12-13T00:00:00+00:00,https://24ways.org/2012/redesigning-the-media-query/,code
90,Monkey Business,"“Too expensive.” “Over-priced.” “A bit rich.”

They all mean the same thing.

When you say that something’s too expensive, you’re doing much more than commenting on a price. You’re questioning the explicit or implicit value of a product or a service. You’re asking, “Will I get out of it what you want me to pay for it?” You’re questioning the competency, judgement and possibly even integrity of the individual or company that gave you that price, even though you don’t realise it. You might not be saying it explicitly, but what you’re implying is, “Have you made a mistake?”, “Am I getting the best deal?”, “Are you being honest with me?”, “Could I get this cheaper?”

Finally, you’re being dishonest, because deep down you know all too well that there’s no such thing as too expensive. 

Why? 

It doesn’t matter what you’re questioning the price of. It could be a product, a service or the cost of an hour, day or week of someone’s time. Whatever you’re buying, too expensive is always an excuse. Saying it shifts acceptability of a price back to the person who gave it. What you should say, but are too afraid to admit, is:


	“It’s more money than I wanted to pay.”
	“It’s more than I estimated it would cost.”
	“It’s more than I can afford.”


Everyone who’s given a price for a product or service will have been told at some point that it’s too expensive. It’s never comfortable to hear that. Thoughts come thick and fast: “What do I do?” “How do I react?” “Do I really want the business?” “Am I prepared to negotiate?” “How much am I willing to compromise?”

It’s easy to be defensive when someone questions a price, but before you react, stay calm and remember that if someone says what you’re offering is too expensive, they’re saying more about themselves and their situation than they are about your price. Learn to read that situation and how to follow up with the right questions.

Imagine you’ve quoted someone for a week of your time. “That’s too expensive,” they respond. How should you handle that? Think about what they might otherwise be saying.



“It’s more money than I want to pay” may mean that they don’t understand the value of your service. How could you respond?

Start by asking what similar projects they’ve worked on and the type of people they worked with. Find out what they paid and what they got for their money, because it’s possible what you offer is different from what they had before. Ask if they saw a return on that previous investment. Maybe their problem isn’t with your headline price, but the value they think they’ll receive. Put the emphasis on value and shift the conversation to what they’ll gain, rather than what they’ll spend.

It’s also possible they can’t distinguish your service from those of your competitors, so now would be a great time to explain the differences. Do you work faster? Explain how that could help them launch faster, get customers faster, make money faster. Do you include more? Emphasise that, and how unique the experience of working with you will be.



“It’s more than I estimated it would cost” could mean that your customer hasn’t done their research properly. You’d never suggest that to them, of course, but you should ask how they’ve arrived at their estimate. Did they base it on work they’ve purchased previously? How long ago was that? Does it come from comparable work or from a different sector?

Help your customer by explaining how you arrived at your estimate. Break down each element and while you’re doing that, emphasise the parts of your process that you know will appeal to them. If you know that they’ve had difficulty with something in the past, explain how your approach will benefit them. People almost always value a positive experience more than the money they’ll save.



“It’s more than I can afford” could mean they can’t afford what you offer at all, but it could also mean they can’t afford it right now or all at once. So ask if they could afford what you’re asking if they spread payment over a longer period? Ask, “Would that mean you’ll give me the business?”

It’s possible they’re asking for too much for what they can afford to pay. Will they compromise? Can you reach an agreement on something less? Ask, “If we can agree what’s in and what’s out, will you give me the business?”

What can they afford? When you know, you’re in a good position to decide if the deal makes good business sense, for both of you. Ask, “If I can match that price, will you give me the business?”

There’s no such thing as “a bit rich”, only ways for you to get to know your customer better. There’s no such thing as “over-priced”, only opportunities for you to explain yourself better. You should relish those opportunities. There’s really also no such thing as “too expensive”, just ways to set the tone for your relationship and help you develop that relationship to a point where money will be less of a deciding factor.

91,Infinite Canvas: Moving Beyond the Page,"Remember Web 2.0? I do. In fact, that phrase neatly bifurcates my life on the internet. Pre-2.0, I was occupied by chatting on AOL and eventually by learning HTML so I could build sites on Geocities. Around 2002, however, I saw a WYSIWYG demo in Dreamweaver. The instructor was dragging boxes and images around a canvas. With a few clicks he was able to build a dynamic, single-page interface. Coming from the world of tables and inline HTML styles, I was stunned.

As I entered college the next year, the web was blossoming: broadband, Wi-Fi, mobile (proud PDA owner, right here), CSS, Ajax, Bloglines, Gmail and, soon, Google Maps. I was a technology fanatic and a hobbyist web developer. For me, the web had long been informational. It was now rapidly becoming something else, something more: sophisticated, presentational, actionable.

In 2003 we watched as the internet changed. The predominant theme of those early Web 2.0 years was the withering of Internet Explorer 6 and the triumph of web standards. Upon cresting that mountain, we looked around and collectively breathed the rarefied air of pristine HMTL and CSS, uncontaminated by toxic hacks and forks – only to immediately begin hurtling down the other side at what is, frankly, terrifying speed.

Ten years later, we are still riding that rocket. Our days (and nights) are spent cramming for exams on CSS3 and RWD and Sass and RESS. We are the proud, frazzled owners of tiny pocket computers that annihilate the best laptops we could have imagined, and the architects of websites that are no longer restricted to big screens nor even segregated by device. We dragoon our sites into working any time, anywhere. At this point, we can hardly ask the spec developers to slow down to allow us to catch our breath, nor should we. It is, without a doubt, a most wonderful time to be a web developer.

But despite the newfound luxury of rounded corners, gradients, embeddable fonts, low-level graphics APIs, and, glory be, shadows, the canyon between HTML and native appears to be as wide as ever. The improvements in HTML and CSS have, for the most part, been conveniences rather than fundamental shifts. What I’d like to do now, if you’ll allow me, is outline just a few of the remaining gaps that continue to separate web sites and applications from their native companions.

What I’d like for Christmas

There is one irritant which is the grandfather of them all, the one from which all others flow and have their being, and it is, simply, the page refresh. That’s right, the foundational principle of the web is our single greatest foe. To paraphrase a patron saint of designers everywhere, if you see a page refresh, we blew it.

The page refresh brings with it, of course, many noble and lovely benefits: addressability, for one; and pagination, for another. (See also caching, resource loading, and probably half a dozen others.) Still, those concerns can be answered (and arguably answered more compellingly) by replacing the weary page with the young and hearty document. Flash may be dead, but it has many lessons yet to bequeath.

Preparing a single document when the site loads allows us to engage the visitor in a smooth and engrossing experience. We have long known this, of course. Twitter was not the first to attempt, via JavaScript, to envelop the user in a single-page application, nor the first to abandon it. Our shared task is to move those technologies down the stack, to make them more primitive, so that the next Twitter can be built with the most basic combination of HTML and CSS rather than relying on complicated, slow, and unreliable scripted solutions.

So, let’s take a look at what we can do, right now, that we might have a better idea of where our current tools fall short.

A print magazine in HTML clothing

Like many others, I suspect, one of my earliest experiences with publishing was laying out newsletters and newspapers on a computer for print. If you’ve ever used InDesign or Quark or even Microsoft Publisher, you’ll remember reflowing content from page to page. The advent of the internet signaled, in many ways, the abandonment of that model. Articles were no longer constrained by the physical limitations of paper. In shedding our chains, however, it is arguable that we’ve lost something useful. We had a self-contained and complete package, a closed loop. It was a thing that could be handled and finished, and doing so provided a sense of accomplishment that our modern, infinitely scrolling, ever-fractal web of content has stolen.

For our purposes today, we will treat 24 ways as the online equivalent of that newspaper or magazine. A single year’s worth of articles could easily be considered an issue. Right now, navigating between articles means clicking on the article you’d like to view and being taken to that specific address via a page reload. If Drew wanted to, it wouldn’t be difficult to update the page in place (via JavaScript) and change the address (again via JavaScript with the History API) to reflect the new content found at the new location. But what if Drew wanted to do that without  JavaScript? And what if he wanted the site to not merely load the content but actually whisk you along the page in a compelling and delightful way, à la the Mag+ demo we all saw a few years ago when the iPad was first introduced? Uh, no.

We’re all familiar with websites that have attempted to go beyond the page by weaving many chunks of content together into a large document and for good reason. There is tremendous appeal in opening and exploring the canvas beyond the edges of our screens.

In one rather straightforward example from last year, Mozilla contacted Full Stop to build a website promoting Aza Raskin’s proposal for a set of Creative Commons-style privacy icons. Like a lot of the sites we build (including our own), the amount of information we were presenting was minimal. In these instances, we encourage our clients to consider including everything on a single page. The result was a horizontally driven site that was, if not whimsical, at least clever and attractive to the intended audience. An experience that is taken for granted when using device-native technology is utterly, maddeningly impossible to replicate on the web without jumping through JavaScript hoops.

In another, more complex example, we again had the pleasure of working with Aza earlier this year, this time on a redesign of the Massive Health website. Our assignment was to design and build a site that communicated Massive’s commitment to modern personal health. The site had to be visually and interactively stunning while maintaining a usable and clear interface for the casual visitor. Our solution was to extend the infinite company logo into a ribbon that carried the visitor through the site narrative. It also meant we’d be asking the browser to accommodate something it was never designed to handle: a non-linear design. (Be sure to play around. There’s a lot going on under the hood. We were also this close to a ZUI, if WebKit didn’t freak out when pages were scaled beyond 10×.) Despite the apparent and deliberate design simplicity, the techniques necessary to implement it are anything but. From updating the URL to moving the visitor from section to section, we’re firmly in JavaScript territory. And that’s a shame.

What can we do?

We might not be able to specify these layouts in HTML and CSS just yet, but that doesn’t mean we can’t learn a few new tricks while we wait. Let’s see how close we can come to recreating the privacy icons design, the Massive design, or the Mag+ design without resorting to JavaScript.

A horizontally paginated site

The first thing we’re going to need is the concept of a page within our HTML document. Using plain old HTML and CSS, we can stack a series of <div>s sideways (with a little assist from our new friend, the viewport-width unit, not that he was strictly necessary). All we need to know is how many pages we have. (And, boy, wouldn’t it be nice to be able to know that without having to predetermine it or use JavaScript?)

.window {
overflow: hidden;
  width: 100%;
}
.pages {
  width: 200vw;
}
.page {
  float: left;
  overflow: hidden;
  width: 100vw;
}

If you look carefully, you’ll see that the conceit we’ll use in the rest of the demos is in place. Despite the document containing multiple pages, only one is visible at any given time. This allows us to keep the user focused on the task (or content) at hand.

By the way, you’ll need to use a modern, WebKit-based browser for these demos. I recommend downloading the WebKit nightly builds, Chrome Canary, or being comfortable with setting flags in Chrome.

A horizontally paginated site, with transitions

Ah, here’s the rub. We have functional navigation, but precious few cues for the user. It’s not much good shoving the visitor around various parts of the document if they don’t get the pleasant whooshing experience of the journey. You might be thinking, what about that new CSS selector, target-something…? Well, my friend, you’re on the right track. Let’s test it. We’re going to need to use a bit of sleight of hand. While we’d like to simply offset the containing element by the number of pages we’re moving (like we did on Massive), CSS alone can’t give us that information, and that means we’re going to need to fake it by expanding and collapsing pages as you navigate. Here are the bits we’re going to need:

.page {
  -webkit-transition: width 1s; // Naturally you're going to want to include all the relevant prefixes here
  float: left;
  left: 0;
  overflow: hidden;
  position: relative;
  width: 100vw;
}
.page:not(:target) {
  width: 0;
}

Ah, but we’re not fooling anyone with that trick. As soon as you move beyond a single page, the visitor’s disbelief comes tumbling down when the linear page transitions are unaffected by the distance the pages are allegedly traveling. And you may have already noticed an even more fatal flaw: I secretly linked you to the first page rather than the unadorned URL. If you visit the same page with no URL fragment, you get a blank screen. Sure, we could force a redirect with some server-side trickery, but that feels like cheating. Perhaps if we had the CSS4 subject selector we could apply styles to the parent based on the child being targeted by the URL. We might also need a few more abilities, like determining the total number of pages and having relative sibling selectors (e.g. nth-sibling), but we’d sure be a lot closer.

A horizontally paginated site, with transitions – no cheating

Well, what other cards can we play? How about the checkbox hack? Sure, it’s a garish trick, but it might be the best we can do today. Check it out. 

label {
  cursor: pointer;
}
input {
 display: none;
}
input:not(:checked) + .page {
  max-height: 100vh;
  width: 0;
}

Finally, we can see the first page thanks to the state we are able to set on the appropriate radio button. Of course, now we don’t have URLs, so maybe this isn’t a winning plan after all. While our HTML and CSS toolkit may feel primitive at the moment, we certainly don’t want to sacrifice the addressability of the web. If there’s one bedrock principle, that’s it.

A horizontally paginated site, with transitions – no cheating and a gorgeous homepage

Gorgeous may not be the right word, but our little magazine is finally shaping up. Thanks to the CSS regions spec, we’ve got an exciting new power, the ability to begin an article in one place and bend it to our will. (Remember, your everyday browser isn’t going to work for these demos. Try the WebKit nightly build to see what we’re talking about.) As with the rest of the examples, we’re clearly abusing these features. Off-canvas layouts (you can thank Luke Wroblewski for the name) are simply not considered to be normal patterns… yet.

Here’s a quick look at what’s going on:

.excerpt-container {
  float: left;
  padding: 2em;
  position: relative;
  width: 100%;
}
.excerpt {
  height: 16em;
}
.excerpt_name_article-1,
.page-1 .article-flow-region {
  -webkit-flow-from: article-1;
}
.article-content_for_article-1 {
  -webkit-flow-into: article-1;
}

The regions pattern is comprised of at least three components: a beginning; an ending; and a source. Using CSS, we’re able to define specific elements that should be available for the content to flow through. If magazine-style layouts are something you’re interested in learning more about (and you should be), be sure to check out the great work Adobe has been doing.

Looking forward, and backward

As designers, builders, and consumers of the web, we share a desire to see the usability and enjoyability of websites continue to rise. We are incredibly lucky to be working in a time when a three-month-old website can be laughably outdated. Our goal ought to be to improve upon both the weaknesses and the strengths of the web platform. We seek not only smoother transitions and larger canvases, but fine-grained addressability. Our URLs should point directly and unambiguously to specific content elements, be they pages, sections, paragraphs or words. Moreover, off-screen design patterns are essential to accommodating and empowering the multitude of devices we use to access the web. We should express the desire that interpage links take advantage of the CSS transitions which have been put to such good effect in every other aspect of our designs. Transitions aren’t just nice to have, they’re table stakes in the highly competitive world of native applications. 

The tools and technologies we have right now allow us to create smart, beautiful, useful webpages. With a little help, we can begin removing the seams and sutures that bind the web to an earlier, less sophisticated generation.",2012,Nathan Peretic,nathanperetic,2012-12-21T00:00:00+00:00,https://24ways.org/2012/infinite-canvas-moving-beyond-the-page/,code
80,HTML5 Video Bumpers,"Video is a bigger part of the web experience than ever before. With native browser support for HTML5 video elements freeing us from the tyranny of plugins, and the availability of faster internet connections to the workplace, home and mobile networks, it’s now pretty straightforward to publish video in a way that can be consumed in all sorts of ways on all sorts of different web devices.

I recently worked on a project where the client had shot some dedicated video shorts to publish on their site. They also had some five-second motion graphics produced to top and tail the videos with context and branding. This pretty common requirement is a great idea on the web, where a user might land at your video having followed a link and be viewing a page without much context.

Known as bumpers, these short introduction clips help brand a video and make it look a lot more professional.



Adding bumpers to a video

The simplest way to add bumpers to a video would be to edit them on to the start and end of the video file itself. Cooking the bumpers into the video file is easy, but should you ever want to update them it can become a real headache. If the branding needs updating, for example, you’d need to re-edit and re-encode all your videos. Not a fun task.

What if the bumpers could be added dynamically? That would enable you to use the same bumper for multiple videos (decreasing download time for users who might watch more than one) and to update the bumpers whenever you wanted. You could change them seasonally, update them for special promotions, run different advertising slots, perform multivariate testing, or even target different bumpers to different users.

The trade-off, of course, is that if you dynamically add your bumpers, there’s a chance that a user in a given circumstance might not see the bumper. For example, if the main video feature was uploaded to YouTube, you’d have no way to control the playback. As always, you need to weigh up the pros and cons and make your choice.

HTML5 bumpers

If you wanted to dynamically add bumpers to your HTML5 video, how would you go about it? That was the question I found myself needing to answer for this particular client project.

My initial thought was to treat it just like an image slideshow. If I were building a slideshow that moved between images, I’d use CSS absolute positioning with z-index to stack the images up on top of each other in a pile, with the first image on top. To transition to the second image, I’d use JavaScript to fade the top image out, revealing the second image beneath it.



Now that video is just a native object in the DOM, just like an image, why not do the same? Stack the videos up with the opening bumper on top, listen for the video’s onended event, and fade it out to reveal the main feature behind. Good idea, right?

Wrong

Remember that this is the web. It’s never going to be that easy. The problem here is that many non-desktop devices use native, dedicated video players. Think about watching a video on a mobile phone – when you play the video, the phone often goes full-screen in its native player, leaving the web page behind. There’s no opportunity to fade or switch z-index, as the video isn’t being viewed in the page. Your page is left powerless. Powerless!



So what can we do? What can we control?

Those of us with particularly long memories might recall a time before CSS, when we’d have to use JavaScript to perform image rollovers. As CSS background images weren’t a practical reality, we would use lots of <img> elements, and perform a rollover by modifying the src attribute of the image. 

Turns out, this old trick of modifying the source can help us out with video, too. In most cases, modifying the src attribute of a <video> element, or perhaps more likely the src attribute of a source element, will swap from one video to another.

Swappin’ it

Let’s take a deliberately simple example of a super-basic video tag:

<video src=""mycat.webm"" controls>no fallback coz i is lame, innit.</video>

We could very simply write a script to find all video tags and give them a new src to show our bumper.

<script>
	var videos, i, l;
	videos = document.getElementsByTagName('video');
	for(i=0, l=videos.length; i<l; i++) {
		videos[i].setAttribute('src', 'bumper-in.webm');
	}
</script>

View the example in a browser with WebM support. You’ll see that the video is swapped out for the opening bumper. Great!

Beefing it up

Of course, we can’t just publish video in one format. In practical use, you need a <video> element with multiple <source> elements containing your different source formats.

<video controls>
    <source src=""mycat.mp4"" type=""video/mp4"" />
    <source src=""mycat.webm"" type=""video/webm"" />
    <source src=""mycat.ogv"" type=""video/ogg"" />
</video>

This time, our script needs to loop through the sources, not the videos. We’ll use a regular expression replacement to swap out the file name while maintaining the correct file extension.

<script>
    var sources, i, l, orig;
    sources = document.getElementsByTagName('source');
    for(i=0, l=sources.length; i<l; i++) {
        orig = sources[i].getAttribute('src');
        sources[i].setAttribute('src', orig.replace(/(w+).(w+)/, 'bumper-in.$2'));
        // reload the video
        sources[i].parentNode.load();
    }
</script>

The difference this time is that when changing the src of a <source> we need to call the .load() method on the video to get it to acknowledge the change.

See the code in action, this time in a wider range of browsers.

But, my video!

I guess we should get the original video playing again. Keeping the same markup, we need to modify the script to do two things:


	Store the original src in a data- attribute so we can access it later
	Add an event listener so we can detect the end of the bumper playing, and load the original video back in


As we need to loop through the videos this time to add the event listener, I’ve moved the .load() call into that loop. It’s a bit more efficient to call it only once after modifying all the video’s sources.

<script>
var videos, sources, i, l, orig;
sources = document.getElementsByTagName('source');
for(i=0, l=sources.length; i<l; i++) {
    orig = sources[i].getAttribute('src');
    sources[i].setAttribute('data-orig', orig);
    sources[i].setAttribute('src', orig.replace(/(w+).(w+)/, 'bumper-in.$2'));
}
videos = document.getElementsByTagName('video');
for(i=0, l=videos.length; i<l; i++) {
    videos[i].load();
    videos[i].addEventListener('ended', function(){
        sources = this.getElementsByTagName('source');
        for(i=0, l=sources.length; i<l; i++) {
            orig = sources[i].getAttribute('data-orig');
            if (orig) {
                sources[i].setAttribute('src', orig);
            }
            sources[i].setAttribute('data-orig','');
        }
        this.load();
        this.play();
    });
}
</script>

Again, view the example to see the bumper play, followed by our spectacular main feature. (That’s my cat, Widget. His interests include sleeping and internet marketing.)

Tidying things up

The final thing to do is add our closing bumper after the main video has played. This involves the following changes:


	We need to keep track of whether the src has been changed, so we only play the video if it’s changed. I’ve added the modified variable to track this, and it stops us getting into a situation where the video just loops forever.
	Add an else to the event listener, for when the orig is false (so the main feature has been playing) to load in the end bumper. We also check that we’re not already playing the end bumper. Because looping.


<script>
var videos, sources, i, l, orig, current, modified;
sources = document.getElementsByTagName('source');
for(i=0, l=sources.length; i<l; i++) {
   orig = sources[i].getAttribute('src');
   sources[i].setAttribute('data-orig', orig);
   sources[i].setAttribute('src', orig.replace(/(w+).(w+)/, 'bumper-in.$2'));
}
videos = document.getElementsByTagName('video');
for(i=0, l=videos.length; i<l; i++) {
   videos[i].load();
   modified = false;
   videos[i].addEventListener('ended', function(){
      sources = this.getElementsByTagName('source');
      for(i=0, l=sources.length; i<l; i++) {
         orig = sources[i].getAttribute('data-orig');
         if (orig) {
            sources[i].setAttribute('src', orig);
            modified = true;
         }else{
            current = sources[i].getAttribute('src');
            if (current.indexOf('bumper-out')==-1) {
               sources[i].setAttribute('src', current.replace(/([w]+).(w+)/, 'bumper-out.$2'));
               modified = true;
            }else{
               this.pause();
               modified = false;
            }
         }
         sources[i].setAttribute('data-orig','');
      }
      if (modified) {
         this.load();
         this.play();
      }
   });
}
</script>

Yo ho ho, that’s a lot of JavaScript. See it in action – you should get a bumper, the cat video, and an end bumper.

Of course, this code works fine for demonstrating the principle, but it’s very procedural. Nothing wrong with that, but to do something similar in production, you’d probably want to make the code more modular to ease maintainability. Besides, you may want to use a framework, rather than basic JavaScript. 

The end credits

One really important principle here is that of progressive enhancement. If the browser doesn’t support JavaScript, the user won’t see your bumper, but they will get the main video. If the browser supports JavaScript but doesn’t allow you to modify the src (as was the case with older versions of iOS), the user won’t see your bumper, but they will get the main video.

If a search engine or social media bot grabs your page and looks for content, they won’t see your bumper, but they will get the main video – which is absolutely what you want.

This means that if the bumper is absolutely crucial, you may still need to cook it into the video. However, for many applications, running it dynamically can work quite well.

As always, it comes down to three things:


	Measure your audience: know how people access your site
	Test the solution: make sure it works for your audience
	Plan for failure: it’s the web and that’s how things work ‘round these parts


But most of all play around with it, have fun and build something awesome.",2012,Drew McLellan,drewmclellan,2012-12-01T00:00:00+00:00,https://24ways.org/2012/html5-video-bumpers/,code
73,How to Make Your Site Look Half-Decent in Half an Hour,"Programmers like me are often intimidated by design – but a little effort can give a huge return on investment. Here are one coder’s tips for making any site quickly look more professional. 

I am a programmer. I am not a designer. I have a degree in computer science, and I don’t mind Comic Sans. (It looks cheerful. Move on.)

But although I am a programmer, I want to make my sites look attractive. This is partly out of vanity, and partly realism. Vanity because I want people to think my work is good, and realism because the research shows that people won’t think a site is credible unless it also looks attractive.

For a very long time after I became a programmer, I was scared of design. Design seemed to consist of complicated rules that weren’t written down anywhere, plus an unlearnable sense of taste, possessed only by a black-clad elite. 

But a little while ago, I decided to do my best to hack what it took to make my own projects look vaguely attractive. And although this doesn’t come close to the effect a professional designer could achieve, gathering these resources for improving a site’s look and feel has been really helpful. 

If I hadn’t figured out some basic design shortcuts, it’s unlikely that a weekend hack of mine would have ended up on page three of the Daily Mail. And too often now, I see excellent programming projects that don’t reach the audience they deserve, simply because their design doesn’t match their execution. 

So, if you are a developer, my Christmas present to you is this: my own collection of hacks that, used rightly, can make your personal programming projects look professional, quickly. None are hard to learn, most are free, and they let you focus on writing code.

One thing to note about these tips, though. They are a personal, pragmatic compilation. They are suggestions, not a definitive guide. You will definitely get better results by working with a professional designer, and by studying design more deeply. 

If you are a designer, I would love to hear your suggestions for the best tools that I’ve missed, and I’d love to know how we programmers can do things better.

With that, on to the tools…

1. Use Bootstrap

If you’re not already using Bootstrap, start now. I really think that Bootstrap is one of the most significant technical achievements of the last few years: it democratizes the whole process of web design. 

Essentially, Bootstrap is a a grid system, with a bunch of common elements. So you can lay your site out how you want, drop in simple elements like forms and tables, and get a good-looking, consistent result, without spending hours fiddling with CSS. You just need HTML. 

Another massive upside is that it makes it easy to make any site responsive, so you don’t have to worry about writing media queries. Go, get Bootstrap and check out the examples. To keep your site lightweight, you can customize your download to include only the elements you want.  

If you have more time, then Mark Otto’s article on why and how Bootstrap was created at Twitter is well worth a read. 

2. Pimp Bootstrap

Using Bootstrap is already a significant advance on not using Bootstrap, and massively reduces the tedium of front-end development. But you also run the risk of creating Yet Another Bootstrap Site, or Hack Day Design, as it’s known. 

If you’re really pressed for time, you could buy a theme from Wrap Bootstrap. These are usually created by professional designers, and will give a polish that we can’t achieve ourselves. Your site won’t be unique, but it will look good quickly. 

Luckily, it’s pretty easy to make Bootstrap not look too much like Bootstrap – using fonts, CSS effects, background images, colour schemes and so on. Most of the rest of this article covers different ways to achieve this. 

We are going to customize this Bootstrap example page.

This already has some custom CSS in the <head>. We’ll pull it all out, and create a new CSS file, custom.css. Then we add a reference to it in the header. Now we’re ready to start customizing things.



3. Fonts

Web fonts are one of the quickest ways to make your site look distinctive, modern, and less Bootstrappy, so we’ll start there. 

First, we can add some sweet fonts, from Google Web Fonts. The intimidating bit is choosing fonts that look nice together. Luckily, there are plenty of suggestions around the web: we’re going to use one of DesignShack’s suggested free Google Fonts pairings. Our fonts are Corben (for headings) and Nobile (for body copy). 

Then we add these files to our <head>. 

<link href=""http://fonts.googleapis.com/css?family=Corben:bold"" rel=""stylesheet"" type=""text/css"">
 <link href=""http://fonts.googleapis.com/css?family=Nobile"" rel=""stylesheet"" type=""text/css"">

…and this to custom.css: 

h1, h2, h3, h4, h5, h6 {
    font-family: 'Corben', Georgia, Times, serif;
}
p, div {
    font-family: 'Nobile', Helvetica, Arial, sans-serif;
}

Now our example looks like this. It’s not going to win any design awards, but it’s immediately better:



I also recommend the web font services Fontdeck, or Typekit – these have a wider selection of fonts, and are worth the investment if you regularly need to make sites look good. For more font combinations, Just My Type suggests appealing pairings from Typekit. Finally, you can experiment with type pairing ideas at Type Connection. For the design background on pairing fonts, Typekit’s post is worth a read. 

4. Textures

An instant way to make a site look classy is to use textures. You know the grey, stripy, indefinably elegant background on 24ways.org? That.

If only there was a superb resource listing attractive, free, ready-to-use textures… Oh wait, there’s Atle Mo’s Subtle Patterns. 

We’re going to use Cream Dust, for an effect that can only be described as subtle. We download the file to a new /img/ directory, then add this to the CSS file:

body { 
    background: url(/img/cream_dust.png) repeat 0 0;
}

Bang:



For some design background on patterns, I recommend reading through Smashing Magazine’s guidelines on textures. (TL;DR version: use textures to enhance beauty, and clarify the information architecture of your site; but don’t overdo it, or inadvertently obscure your text.)

Still more to do, though. Onwards. 

5. Icons

Last year’s 24 ways taught us to use icon fonts for our site icons. 

This is great for the time-pressed coder, because icon fonts don’t just cut down on HTTP requests – they’re a lot quicker to set up than image-based icons, too. 

Bootstrap ships with an extensive, free for commercial use icon set in the shape of Font Awesome. Its icons are safe for screen readers, and can even be made to work in IE7 if needed (we’re not going to bother here). 

To start using these icons, just download Font Awesome, and add the /fonts/ directory to your site and the font-awesome.css file into your /css/ directory. Then add a reference to the CSS file in your header:

<link rel=""stylesheet"" href=""/css/font-awesome.css"">

Finally, we’ll add a truck icon to the main action button, as follows. Why a truck? Why not?

<a class=""btn btn-large btn-success"" href=""#""><i class=""icon-truck""></i> Sign up today</a>

We’ll also tweak our CSS file to stop the icon nudging up against the button text:

.jumbotron .btn i { 
    margin-right: 8px;  
}

And this is how it looks:



Not the most exciting change ever, but it livens up the page a bit. The licence is CC-BY-3.0, so we also include a mention of Font Awesome and its URL in the source code. 

If you’d like something a little more distinctive, Shifticons lets you pay a few cents for individual icons, with the bonus that you only have to serve the icons you actually use, which is more efficient. Its icons are also friendly to screen readers, but won’t work in IE7. 

6. CSS3

The next thing you could do is add some CSS3 goodness. It can really help the key elements of the site stand out. 

If you are pressed for time, just adding box-shadow and text-shadow to emphasize headings and standouts can be useful: 

h1 { 
    text-shadow: 1px 1px 1px #ccc;
}
.div-that-you want-to-stand-out { 
    box-shadow: 0 0 1em 1em #ccc;
}

We have a little more time though, so we’re going to do something more subtle. We’ll add a radial gradient behind the main heading, using an online gradient editor. 

The output is hefty, but you can see it in the CSS. Note that we also need to add the following to our HTML, for IE9 support: 

<!--[if gte IE 9]>
  <style type=""text/css"">
    .gradient {
       filter: none;
    }
  </style>
<![endif]-->

And the effect – I don’t know what a designer would think, but I like the way it makes the heading pop.



For a crash course in useful modern CSS effects, I highly recommend CodeSchool’s online course in Functional HTM5 and CSS3. It costs money ($25 a month to subscribe), but it’s worth it for the time you’ll save. As a bonus, you also get access to some excellent JavaScript, Ruby and GitHub courses. 

(Incidentally, if you find yourself fighting with basic float and display attributes in CSS – and there’s no shame in it, CSS layout is not intuitive – I recommend the CSS Cross-Country course at CodeSchool.)

7. Add a twist

We could leave it there, but we’re going to add a background image, and give the site some personality. 

This is the area of design that I think many programmers find most intimidating. How do we create the graphics and photographs that a designer would use? The answer is iStockPhoto and its competitors – online image libraries where you can find and pay for images. They won’t be unique, but for our purposes, that’s fine. 

We’re going to use a Christmassy image. For a twist, we’re going to use Backstretch to make it responsive. 

We must pay for the image, then download it to our /img/ directory. Then, we set it as our <body>’s background-image, by including a JavaScript file with just the following line: 

$.backstretch(""/img/winter.jpg"");

We also reset the subtle pattern to become the background for our container image. It would look much better transparent, so we can use this technique in GIMP to make it see-through:

.container-narrow {
    background: url(/img/cream_dust_transparent.png) repeat 0 0;
}

We also fiddle with the padding on body and .container-narrow a bit, and this is the result: 



(Aside: If this were a real site, I’d want to buy images in multiple sizes and ensure that Backstretch chose the most appropriately sized image for our screen, perhaps using responsive images.)

How to find the effects that make a site interesting? I keep a set of bookmarks for interesting JavaScript and CSS effects I might want to use someday, from realistic shadows to animating grids. The JavaScript Weekly newsletter is a great source of ideas. 

8. Colour schemes

We’re just about getting there – though we’re probably past half an hour now – but that button and that menu still both look awfully Bootstrappy. 

Real sites, with real designers, have a colour palette, carefully chosen to harmonize and match the brand profile. For our purposes, we’re just going to borrow some colours from the image. We use Gimp’s colour picker tool to identify the hex values of the blue of the snow. Then we can use Color Scheme Designer to find contrasting, but complementary, colours. 

Finally, we use those colours for our central button. There are lots of tools to help us do this, such as Bootstrap Buttons. The new HTML is quite long, so I won’t paste it all here, but you can find it in the CSS file. 

We also reset the colour of the pills in the navigation menu, which is a bit easier: 

.nav-pills > .active > a, .nav-pills > .active > a:hover {
    background-color: #FF9473;
}

I’m not sure if the result is great to be honest, but at least we’ve lost those Bootstrap-blue buttons:



Another way to do it, if you didn’t have an image to match, would be to borrow an attractive colour scheme. Colourlovers is a community where people create and share ready-made colour palettes. 

The key thing is to find a palette with an open licence, so you can legitimately use it. Unfortunately, you can’t search for palettes by licence type, but many do have open licences. Here’s a popular palette with a CC-BY-SA licence that allows reuse with attribution.  

As above, you can use the hex values from the palette in your custom CSS, and bask in the newly colourful results.

With the above techniques, you can make a site that is starting to look slightly more professional, pretty quickly. 

If you have the time to invest, it’s well worth learning some design principles, if only so that design seems less intimidating and more like fun. As part of my design learning, I read a few introductory design books aimed at coders. The best I found was David Kadavy’s Design for Hackers: Reverse-Engineering Beauty, which explains the basic principles behind choosing colours, fonts, typefaces and layout.

In the introduction to his book, David writes: 


	No group stands to gain more from design literacy than hackers do… The one subject that is exceedingly frustrating for hackers to try to learn is design. Hackers know that in order to compete against corporate behemoths with just a few lines of code, they need to have good, clear design, but the resources with which to learn design are simply hard to find.


Well said. If you have half a day to invest, rather than half an hour, I recommend getting hold of David’s book.

And the journey is over. Perhaps that took slightly more than half an hour, but with practice, using the above techniques can become second nature. What useful tools have I missed? Designers, how would you improve on the above? I would love to know, so please give me your views in the comments.",2012,Anna Powell-Smith,annapowellsmith,2012-12-16T00:00:00+00:00,https://24ways.org/2012/how-to-make-your-site-look-half-decent/,design
76,Giving CSS Animations and Transitions Their Place,"CSS animations and transitions may not sit squarely in the realm of the behaviour layer, but they’re stepping up into this area that used to be pure JavaScript territory. Heck, CSS might even perform better than its JavaScript equivalents in some cases. That’s pretty serious! With CSS’s new tricks blurring the lines between presentation and behaviour, it can start to feel bloated and messy in our CSS files. It’s an uncomfortable feeling.

Here are a pair of methods I’ve found to be pretty helpful in keeping the potential bloat and wire-crossing under control when CSS has its hands in both presentation and behaviour.

Same eggs, more baskets

Structuring your CSS to have separate files for layout, typography, grids, and so on is a fairly common approach these days. But which one do you put your transitions and animations in? The initial answer, as always, is “it depends”.

Small effects here and there will likely sit just fine with your other styles. When you move into more involved effects that require multiple animations and some logic support from JavaScript, it’s probably time to choose none of the above, and create a separate CSS file just for them.

Putting all your animations in one file is a huge help for code organization. Even if you opt for a name less literal than animations.css, you’ll know exactly where to go for anything CSS animation related. That saves time and effort when it comes to editing and maintenance. Keeping track of which animations are still currently used is easier when they’re all grouped together as well. And as an added bonus, you won’t have to look at all those horribly unattractive and repetitive prefixed @-keyframe rules unless you actually need to.

An animations.css file might look something like the snippet below. It defines each animation’s keyframes and defines a class for each variation of that animation you’ll be using. Depending on the situation, you may also want to include transitions here in a similar way. (I’ve found defining transitions as their own class, or mixin, to be a huge help in past projects for me.)

// defining the animation
@keyframes catFall {
 from { background-position: center 0;}
 to {background-position: center 1000px;}
}
@-webkit-keyframes catFall {
 from { background-position: center 0;}
 to {background-position: center 1000px;}
}
@-moz-keyframes catFall {
 from { background-position: center 0;}
 to {background-position: center 1000px;}
}
@-ms-keyframes catFall {
 from { background-position: center 0;}
 to {background-position: center 1000px;}
}

…

// class that assigns the animation

.catsBackground {
 height: 100%;
 background: transparent url(../endlessKittens.png) 0 0 repeat-y;
 animation: catFall 1s linear infinite;
 -webkit-animation: catFall 1s linear infinite;
 -moz-animation: catFall 1s linear infinite;
 -ms-animation: catFall 1s linear infinite;
}

If we don’t need it, why load it?

Having all those CSS animations and transitions in one file gives us the added flexibility to load them only when we want to. Loading a whole lot of things that will never be used might seem like a bit of a waste.

While CSS has us impressed with its motion chops, it falls flat when it comes to the logic and fine-grained control. JavaScript, on the other hand, is pretty good at both those things. Chances are the content of your animations.css file isn’t acting alone. You’ll likely be adding and removing classes via JavaScript to manage your CSS animations at the very least. If your CSS animations are so entwined with JavaScript, why not let them hang out with the rest of the behaviour layer and only come out to play when JavaScript is supported?

Dynamically linking your animations.css file like this means it will be completely ignored if JavaScript is off or not supported. No JavaScript? No additional behaviour, not even the parts handled by CSS.

<script>
document.write('<link rel=""stylesheet"" type=""text/css"" href=""animations.css"">');
</script>

This technique comes up in progressive enhancement techniques as well, but it can help here to keep your presentation and behaviour nicely separated when more than one language is involved. The aim in both cases is to avoid loading files we won’t be using.

If you happen to be doing something a bit fancier – like 3-D transforms or critical animations that require more nuanced fallbacks – you might need something like modernizr to step in to determine support more specifically. But the general idea is the same.

Summing it all up

Using a couple of simple techniques like these, we get to pick where to best draw the line between behaviour and presentation based on the situation at hand, not just on what language we’re using. The power of when to separate and how to reassemble the individual pieces can be even greater if you use preprocessors as part of your process. We’ve got a lot of options! The important part is to make forward-thinking choices to save your future self, and even your current self, unnecessary headaches.",2012,Val Head,valhead,2012-12-08T00:00:00+00:00,https://24ways.org/2012/giving-css-animations-and-transitions-their-place/,code
78,Fluent Design through Early Prototyping,"There’s a small problem with wireframes. They’re not good for showing the kind of interactions we now take for granted – transitions and animations on the web, in Android, iOS, and other platforms. There’s a belief that early prototyping requires a large amount of time and effort, and isn’t worth an early investment. But it’s not true!

It’s still normal to spend a significant proportion of time working in wireframes. Given that wireframes are high-level and don’t show much detail, it’s tempting to give up control and responsibility for things like transitions and other things sidelined as visual considerations. These things aren’t expressed well, and perhaps not expressed at all, in wireframes, yet they critically influence the quality of a product. Rapid prototyping early helps to bring sidelined but significant design considerations into focus.

Speaking fluent design

Fluency in a language means being able to speak it confidently and accurately. The Latin root means flow.

By design fluency, I mean using a set of skills in order to express or communicate an idea. Prototyping is a kind of fluency. It takes designers beyond the domain of grey and white boxes to consider all the elements that make up really good product design.

Designers shouldn’t be afraid of speaking fluent design. They should think thoroughly about product decisions beyond their immediate role — not for the sake of becoming some kind of power-hungry design demigod, but because it will lead to better, more carefully considered product design.

Wireframes are incomplete sentences

Wireframes, once they’ve served their purpose, are a kind of self-imposed restriction.

Mostly made out of grey and white boxes, they deliberately express the minimum. Important details — visuals, nuanced transitions, sounds — are missing. Their appearance bears little resemblance to the final thing. Responsibility for things that traditionally didn’t matter (or exist) is relinquished. Animations and transitions in particular are increasingly relevant to the mobile designer’s methods. And rather than being fanciful and superfluous visual additions to a product, they help to clarify designs and provide information about context.

Wireframes are useful in the early stages. As a designer trying to persuade stakeholders, clients, or peers, sometimes it will be in your interests to only tell half the story. They’re ideal for gauging whether a design is taking the right direction, and they’re the right medium for deciding core things, such as the overall structure and information architecture.

But spending a long time in wireframes means delaying details to a later stage in the project, or to the end, when the priority is shifted to getting designs out of the door. This leaves little time to test, finesse and perfect things which initially seemed to be less important. I think designers should move away from using wireframes as primary documentation once the design has reached a certain level of maturity.

A prototype is multiple complete sentences

Paragraphs, even.

Unlike a wireframe, a prototype is a persuasive storyteller. It can reveal the depth and range of design decisions, not just the layout, but also motion: animations and transitions. If it’s a super-high-fidelity prototype, it’s a perfect vessel for showing the visual design as well. It’s all of these things that contribute to the impression that a product is good… and useful, and engaging, and something you’d like to use.

A prototype is impressive. A good prototype can help to convince stakeholders and persuade clients. With a compelling demo, people can more easily imagine that this thing could actually exist. “Hey”, they’re thinking. “This might actually be pretty good!”

How to make a prototype in no time and with no effort

Now, it does take time and effort to make a prototype. However, good news! It used to require a lot more effort. There are tools that make prototyping much quicker and easier.

If you’re making a mobile prototype (this seems quite likely), you will want to test and show this on the actual device. This sounds like it could be a pain, but there are a few ways to do this that are quite easy.

Keynote, Apple’s presentation software, is an unlikely candidate for a prototyping tool, but surprisingly great and easy for creating prototypes with transitions that can be shown on different devices.

Keynote enables you to do a few useful, excellent things. You can make each screen in your design a slide, which can be linked together to allow you to click through the prototype. You can add customisable transitions between screens. If you want to show a panel that can slide open or closed on your iPad mockup, for example, transitions can also be added to individual elements on the screen. The design can be shown on tablet and mobile devices, and interacted with like it’s a real app. Another cool feature is that you can export the prototype as a video, which works as another effective format for demoing a design.

Overall, Keynote offers a very quick, lightweight way to prototype a design. Once you’ve learned the basics, it shouldn’t take longer than a few hours – at most – to put together a respectable clickable prototype with transitions.

Download the interactive MOV example

Holly icon by Megan Sheehan from The Noun Project

This is a Quicktime movie exported from Keynote. This version is animated for demonstration purposes, but download the interactive original and you can click the screen to move through the prototype. It demonstrates the basic interactivity of an iPhone app. This anonymised example was used on a project at Fjord to create a master example of an app’s transitions.

Prototyping drawbacks, and perceived drawbacks

If prototyping is so great, then why do we leave it to the end, or not bother with it at all? There are multiple misconceptions about prototyping: they’re too difficult to make; they take too much time; or they’re inaccurate (and dangerous) documentation.

A prototype is a preliminary model. There should always be a disclaimer that it’s not the real thing to avoid setting up false expectations.

A prototype doesn’t have to be the main deliverable. It can be a key one that’s supported by visual and interaction specifications. And a prototype is a lightweight means of managing and reflecting changes and requirements in a project.

An actual drawback of prototyping is that to make one too early could mean being gung-ho with what you thought a client or stakeholder wanted, and delivering something inappropriate. To avoid this, communicate, iterate, and keep things simple until you’re confident that the client or other stakeholders are happy with your chosen direction.

The key throughout any design project is iteration. Designers build iterative models, starting simple and becoming increasingly sophisticated. It’s a process of iterative craft and evolution. There’s no perfect methodology, no magic recipe to follow.

What to do next

Make a prototype! It’s the perfect way to impress your friends.

It can help to advance a brilliant idea with a fraction of the effort of complete development. Sketches and wireframes are perfect early on in a project, but once they’ve served their purpose, prototypes enable the design to advance, and push thinking towards clarifying other important details including transitions.

For Keynote tutorials, Keynotopia is a great resource. Axure is standard and popular prototyping software many UX designers will already be familiar with; it’s possible to create transitions in Axure. POP is an iPhone app that allows you to design apps on paper, take photos with your phone, and turn them into interactive prototypes. Ratchet is an elegant iPhone prototyping tool aimed at web developers.

There are perhaps hundreds of different prototyping tools and methods. My final advice is not to get bogged down in (or limited by) any particular tool, but to remember you’re making quick and iterative models. Experiment and play!

Prototyping will push you and your designs to a scary place without limitations. No more grey and white boxes, just possibilities!",2012,Rebecca Cottrell,rebeccacottrell,2012-12-10T00:00:00+00:00,https://24ways.org/2012/fluent-design-through-early-prototyping/,ux
86,Flashless Animation,"Animation in a Flashless world

When I splashed down in web design four years ago, the first thing I wanted to do was animate a cartoon in the browser. I’d been drawing comics for years, and I’ve wanted to see them come to life for nearly as long. Flash animation was still riding high, but I didn’t want to learn Flash. I wanted to learn JavaScript!

Sadly, animating with JavaScript was limiting and resource-intensive. My initial foray into an infinitely looping background did more to burn a hole in my CPU than amaze my friends (although it still looks pretty cool). And there was still no simple way to incorporate audio. The browser technology just wasn’t there.

Things are different now. CSS3 transitions and animations can do most of the heavy lifting and HTML5 audio can serve up the music and audio clips. You can do a lot without leaning on JavaScript at all, and when you lean on JavaScript, you can do so much more!

In this project, I’m going to show you how to animate a simple walk cycle with looping audio. I hope this will inspire you to do something really cool and impress your friends. I’d love to see what you come up with, so please send your creations my way at rachelnabors.com!

Note: Because every browser wants to use its own prefixes with CSS3 animations, and I have neither the time nor the space to write all of them out, I will use the W3C standard syntaxes; that is, going prefix-less. You can implement them out of the box with something like Prefixfree, or you can add prefixes on your own. If you take the latter route, I recommend using Sass and Compass so you can focus on your animations, not copying and pasting.

The walk cycle

Walk cycles are the “Hello world” of animation. One of the first projects of animation students is to spend hours drawing dozens of frames to complete a simple loopable animation of a character walking.

Most animators don’t have to draw every frame themselves, though. They draw a few key frames and send those on to production animators to work on the between frames (or tween frames). This is meticulous, grueling work requiring an eye for detail and natural movement. This is also why so much production animation gets shipped overseas where labor is cheaper.

Luckily, we don’t have to worry about our frame count because we can set our own frames-per-second rate on the fly in CSS3. Since we’re trying to impress friends, not animation directors, the inconsistency shouldn’t be a problem. (Unless your friend is an animation director.)

This is a simple walk cycle I made of my comic character Tuna for my CSS animation talk at CSS Dev Conference this year:



The magic lies here:

animation: walk-cycle 1s steps(12) infinite;

Breaking those properties down:

animation: <name> <duration> <timing-function> <iteration-count>;

walk-cycle is a simple @keyframes block that moves the background sprite on .tuna around:

@keyframes walk-cycle {  
    0% {background-position: 0 0; }
    100% {background-position: 0 -2391px;}
}

The background sprite has exactly twelve images of Tuna that complete a full walk cycle. We’re setting it to cycle through the entire sprite every second, infinitely. So why isn’t the background image scrolling down the .tuna container? It’s all down to the timing function steps(). Using steps() let us tell the CSS to make jumps instead of the smooth transitions you’d get from something like linear. Chris Mills at dev.opera wrote in his excellent intro to CSS3 animation :


	Instead of giving a smooth animation throughout, [steps()] causes the animation to jump between a set number of steps placed equally along the duration. For example, steps(10) would make the animation jump along in ten equal steps. There’s also an optional second parameter that takes a value of start or end. steps(10, start) would specify that the change in property value should happen at the start of each step, while steps(10, end) means the change would come at the end.


(Seriously, go read his full article. I’m not going to touch on half the stuff he does because I cannot improve on the basics any more than he already has.)

The background

A cat walking in a void is hardly an impressive animation and certainly your buddy one cube over could do it if he chopped up some of those cat GIFs he keeps using in group chat. So let’s add a parallax background! Yes, yes, all web designers signed a peace treaty to not abuse parallax anymore, but this is its true calling—treaty be damned.



And to think we used to need JavaScript to do this! It’s still pretty CPU intensive but much less complicated. We start by splitting up the page into different layers, .foreground, .midground, and .background. We put .tuna in the .midground.

.background has multiple background images, all set to repeat horizontally:

background-image:
    url(background_mountain5.png),
    url(background_mountain4.png),
    url(background_mountain3.png),
    url(background_mountain2.png),
    url(background_mountain1.png);
background-repeat: repeat-x;

With parallax, things in the foreground move faster than those in the background. Next time you’re driving, notice how the things closer to you move out of your field of vision faster than something in the distance, like a mountain or a large building. We can imitate that here by making the background images on top (in the foreground, closer to us) wider than those on the bottom of the stack (in the distance).

The different lengths let us use one animation to move all the background images at different rates in the same interval of time:   

animation: parallax_bg linear 40s infinite;

The shorter images have less distance to cover in the same amount of time as the longer images, so they move slower.



Let’s have a look at the background’s animation:

@keyframes parallax_bg {  
  0% {
    background-position: -2400px 100%, -2000px 100%, -1800px 100%, -1600px 100%, -1200px 100%;
  }
  100% {
    background-position: 0 100%, 0 100%, 0 100%, 0 100%, 0 100%;
  }
}

At 0%, all the background images are positioned at the negative value of their own widths. Then they start moving toward background-position: 0 100%. If we wanted to move them in the reverse direction, we’d remove the negative values at 0% (so they would start at 2400px 100%, 2000px 100%, etc.). Try changing the values in the codepen above or changing background-repeat to none to see how the images play together.

.foreground and .midground operate on the same principles, only they use single background images.

The music

After finishing the first draft of my original walk cycle, I made a GIF with it and posted it on YTMND with some music from the movie Paprika, specifically the track “The Girl in Byakkoya.” After showing it to some colleagues in my community, it became clear that this was a winning combination sure to drive away dresscode blues. So let’s use HTML5 to get a clip of that music looping in there!

Warning, there is sound. Please adjust your volume or apply headphones as needed.



We’re using HTML5 audio’s loop and autoplay abilities to automatically play and loop a sound file on page load:

<audio loop autoplay>
  <source src=""http://music.com/clip.mp3"" />
</audio>

Unfortunately, you may notice there is a small pause between loops. HTML5 audio, thou art half-baked still. Let’s hope one day the Web Audio API will be able to help us out, but until things improve, we’ll have to hack our way around these shortcomings.

Turns out there’s a handy little script called seamlessLoop.js which we can use to patch this. Mind you, if we were really getting crazy with the Cheese Whiz, we’d want to get out big guns like sound.js. But that’d be overkill for a mere loop (and explaining the Web Audio API might bore, rather than impress your friends)!

Installing seamlessLoop.js will get rid of the pause, and now our walk cycle is complete.

(I’ve done some very rough sniffing to see if the browser can play MP3 files. If not, we fall back to using .ogg formatted clips (Opera and Firefox users, you’re welcome).)

Really impress your friends by adding a run cycle

So we have music, we have a walk cycle, we have parallax. It will be a snap to bring them all together and have a simple, endless animation. But let’s go one step further and knock the socks off our viewers by adding a run cycle.

The run cycle

Tacking a run cycle on to our walk cycle will require a third animation sequence: a transitional animation of Tuna switching from walking to running. I have added all these to the sprite:



Let’s work on getting that transition down. We’re going to use multiple animations on the same .tuna div, but we’re going to kick them off at different intervals using animation-delay—no JavaScript required! Isn’t that magical?



It requires a wee bit of math (not much, it doesn’t hurt) to line them up. We want to:


	Loop the walk animation twice
	Play the transitional cycle once (it has a finite beginning and end perfectly drawn to pick up between the last frame of the walk cycle and the first frame of the run cycle—no looping this baby)
	RUN FOREVER.


Using the pattern animation: <name> <duration> <timing-function> <delay> <iteration-count>, here’s what that looks like:

animation:
    walk-cycle 1s steps(12) 2,
    walk-to-run .75s steps(12) 2s 1,
    run-cycle .75s steps(13) 2.75s infinite;

I played with the times to get make the movement more realistic. You may notice that the running animation looks smoother than the walking animation. That’s because it has 13 keyframes running over .75 second instead of 12 running in one second. Remember, professional animation studios use super-high frame counts. This little animation isn’t even up to PBS’s standards!

The music: extended play with HTML5 audio sprites

My favorite part in the The Girl in Byakkoya is when the calm opening builds and transitions into a bouncy motif. I want to start with Tuna walking during the opening, and then loop the running and bounciness together for infinity.


	The intro lasts for 24 seconds, so we set our 1 second walk cycle to run for 24 repetitions: 
walk-cycle 1s steps(12) 24
	We delay walk-to-run by 24 seconds so it runs for .75 seconds before…
	We play run-cycle at 24.75 seconds and loop it infinitely


For the music, we need to think of it as two parts: the intro and the bouncy loop. We can do this quite nicely with audio sprites: using one HTML5 audio element and using JavaScript to change the play head location, like skipping tracks with a CD player. Although this technique will result in a small gap in music shifts, I think it’s worth using here to give you some ideas.

// Get the audio element
var byakkoya = document.querySelector('audio');
// create function to play and loop audio
function song(a){
    //start playing at 0
    a.currentTime = 0;
    a.play();
    //when we hit 64 seconds...
    setTimeout(function(){
        // skip back to 24.5 seconds and keep playing...
        a.currentTime = 24.55;
        // then loop back when we hit 64 again, or every 59.5 seconds.
        setInterval(function(){
            a.currentTime = 24.55;
        },39450);
    },64000);
}

The load screen

I’ve put it off as long as I can, but now that the music and the CSS are both running on their own separate clocks, it’s imperative that both images and music be fully downloaded and ready to run when we kick this thing off. So we need a load screen (also, it’s nice to give people a heads-up that you’re about to blast them with music, no matter how wonderful that music may be).

Since the two timers are so closely linked, we’d best not run the animations until we run the music:

* { animation-play-state: paused; }

animation-play-state can be set to paused or running, and it’s the most useful thing you will learn today.

First we use an event listener to see when the browser thinks we can play through from the beginning to end of the music without pause for buffering:

byakkoya.addEventListener(""canplaythrough"", function () { });

(More on HTML5 audio’s media events at HTML5doctor.com)

Inside our event listener, I use a bit of jQuery to add class of .playable to the body when we’re ready to enable the play button:

$(""body"").addClass(""playable"");
    $(""#play-me"").html(""Play me."").click(function(){
      song(byakkoya);
      $(""body"").addClass(""playing"");
    });

That .playing class is special because it turns on the animations at the same time we start playing the song:

.playing * { animation-play-state: running; }

The background

We’re almost done here! When we add the background, it needs to speed up at the same time that Tuna starts running. The music picks up speed around 24.75 seconds in, and so we’re going to use animation-delay on those backgrounds, too.

This will require some math. If you try to simply shorten the animation’s duration at the 24.75s mark, the backgrounds will, mid-scroll, jump back to their initial background positions to start the new animation! Argh! So let’s make a new @keyframe and calculate where the background position would be just before we speed up the animation.

Here’s the formula:

new 0% value = delay ÷ old duration × length of image

new 100% value = new 0% value + length of image

Here’s the formula put to work on a smaller scale:



Voilà! The finished animation!



I’ve always wanted to bring my illustrations to life. Then I woke up one morning and realized that I had all the tools to do so in my browser and in my head. Now I have fallen in love with Flashless animation.

I’m sure there will be detractors who say HTML wasn’t meant for this and it’s a gross abuse of the DOM! But I say that these explorations help us expand what we expect from devices and software and challenge us in good ways as artists and programmers. The browser might not be the most appropriate place for animation, but is certainly a fun place to start.

There is so much you can do with the spec implemented today, and so much of the territory is still unexplored. I have not yet begun to show you everything. In eight months I expect this demo will represent the norm, not the bleeding edge. I look forward to seeing the wonderful things you create.

89,"Direction, Distance and Destinations","With all these new smartphones in the hands of lost and confused owners, we need a better way to represent distances and directions to destinations. The immediate examples that jump to mind are augmented reality apps which let you see another world through your phone’s camera. While this is interesting, there is a simpler way: letting people know how far away they are and if they are getting warmer or colder. 

In the app world, you can easily tap into the phone’s array of sensors such as the GPS and compass, but what people rarely know is that you can do the same with HTML. The native versus web app debate will never subside, but at least we can show you how to replicate some of the functionality progressively in HTML and JavaScript.

In this tutorial, we’ll walk through how to create a simple webpage listing distances and directions of a few popular locations around the world. We’ll use JavaScript to access the device’s geolocation API and also attempt to access the compass to get a heading. Both of these APIs are documented, to be included in the W3C geolocation API specification, and can be used on both desktop and mobile devices today.

To get started, we need a list of a few locations around the world. I have chosen the highest mountain peak on each continent so you can see a diverse set of distances and directions.

We can put those into an HTML list to be styled and accessed by JavaScript to create some distance and directions calculations.

The next thing we need to do is check to see if the browser and operating system have geolocation support. To do this we test to see if the function is available or not using a single JavaScript if statement.

<script>
// If this is true, then the method is supported and we can try to access the location
if (navigator.geolocation) {
	navigator.geolocation.getCurrentPosition(geo_success, geo_error);
}
</script>

The if statement will be false if geolocation support is not present, and then it is up to you to do something else instead as a fallback. For this example, we’ll do nothing since our page should work as is and only get progressively better if more functionality is available. 

The if statement will be true if there is support and therefore will continue inside the curly brackets to try to get the location. This should prompt the reader to accept or deny the request to get their location. If they say no, the second function callback is processed, in this case a function called geo_error; whereas if the location is available, it fires the geo_success function callback.

The function geo_error(){ } isn’t that exciting. You can handle this in any way you see fit. The success function is more interesting. We get a position object passed into the function which contains a series of exciting attributes, namely the latitude and longitude of the device’s current location.

function geo_success(position){
	gLat = position.coords.latitude;
	gLon = position.coords.longitude;
}

Now, in the variables gLat and gLon we have the user’s approximate geographical position. We can use this information to start to calculate some distances between where they are and all the destinations.

At the time of writing, you can also get position.coords.heading, but on Windows and iOS devices this returned NULL. In the future, if and when this is supported, this is also where you can easily grab the compass information.

Inside the geo_success function, we want to loop through the HTML to get all of the mountain peaks’ latitudes and longitudes and compute the distance.

...
$('.geo').each(function(){
	// Get the lat/lon from the HTML
	tLat = $(this).find('.lat').html()
	tLon = $(this).find('.lon').html()

	// compute the distances between the current location and this points location
	dist = distance(tLat,tLon,gLat,gLon);

	// set the return values into something useful
	d = parseInt(dist[0]*10)/10;
	a = parseFloat(dist[1]);

	// display the value in the HTML and style the arrow
	$(this).find('.distance').html(d+' km away');
	$(this).find('.direction').css('-webkit-transform','rotate(-' + a + 'deg)');

	// store the arc for later use if compass is available
	$(this).attr('data-arc',a);
}

In the variable d we have the distance between the current location and the location of the mountain peak based on the Haversine Formula. The variable a is the arc, which has a value from 0 to 359.99. This will be useful later if we have compass support. Given these two values we have a distance and a heading to style the HTML.

The next thing we want to do is check to see if the device has a compass and then get access to the the current heading. As we’ll see, there are several ways to do this, some of which work on certain devices but not others. The W3C geolocation spec says that, along with the coordinates, there are several other attributes: accuracy; altitude; and heading. Heading is the direction to true north, which is different than magnetic north! WebKit and Windows return NULL for the heading value, but WebKit has an experimental method to fetch the heading. If you get into accessing these sensors, you’ll have to try to catch a few of these methods to finally get a value. Assuming you do, we can move on to the more interesting display opportunities.

In an ideal world, this would succeed and set a variable we’ll call compassHeading to get a value between 0 and 359.99 degrees. Now we know which direction north is, we also know the direction relative to north of the path to our destination, so we can can subtract the two values to get an arrow to display on the screen. But we’re not finished yet: we also need to get the device’s orientation (landscape or portrait) and subtract the correct amount from the angle for the arrow. Once we have a value, we can use CSS to rotate the arrow the correct number of degrees.

-webkit-transform: rotate(-180deg)

Not all devices support a standard way to access compass information, so in the meantime we need to use a work around. On iOS, you can use the experimental event method e.webkitCompassHeading. We want the compass to update in real time as the device is moved around, so we’ll put this inside an event listener.

window.addEventListener('deviceorientation', function(e) {
	// Loop through all the locations on the page
	$('.geo').each(function(){
		// get the arc value from north we computed and stored earlier
		destination_arc = parseInt($(this).attr('data-arc'))
		compassHeading = e.webkitCompassHeading + window.orientation + destination_arc;
		// find the arrow element and rotate it accordingly
		$(this).find('.direction').css('-webkit-transform','rotate(-' + compassHeading + 'deg)');		
	}
}

As the device is rotated, the compass arrow will constantly be updated. If you want to see an example, you can have a look at this page which shows the distances to all the peaks on each continent.

With progressive enhancement, we slowly layer on additional functionality as we go. The reader will first see the list of locations with a latitude and longitude. If the device is capable and permissions allow, it will then compute the distance. If a compass is available, with the correct permissions it will then add the final layer which is direction.

You should consider this code a stub for your projects. If you are making a hyperlocal webpage with restaurant locations, for example, then consider adding these features. Knowing not only how far away a place is, but also the direction can be hugely important, and since the compass is always active, it acts as a guide to the location. 

Future developments

Improvements to this could include setting a timer and recalling the navigator.geolocation.getCurrentPosition() function and updating the distances. I chose very distant mountains so kilometres made sense, but you can divide again by 1,000 to convert to metres if you are dealing with much nearer places. Walking or driving would change the distances so the ability to refresh would be important. 

It is outside the scope of this article, but if you manage to get this HTML to work offline, then you can make a nice web app which sits on your devices’ homescreens and works even without an internet connection. This could be ideal for travellers in an unknown city looking for your destination. Just with offline storage, base64 encoding and data URIs, it is possible to embed plenty of design and functionality into a small offline webpage.

Now you know how to use JavaScript to look up a destination’s location and figure out the distance and direction – never get lost again.",2012,Brian Suda,briansuda,2012-12-19T00:00:00+00:00,https://24ways.org/2012/direction-distance-and-destinations/,code
93,Design Systems,"The most important part of responsive web design is that, no matter what the viewport width, the content is accessible in an optimum display. The best responsive designs are those that allow you to go from one optimised display to another, but with the feeling that these experiences are part of a greater product whole.

Responsive design: where we’ve been going wrong

Responsive web design was a shock to my web designer system. Those of us who had already been designing sites for mobile probably had the biggest leap to make. We might have been detecting user agents in order to deliver a mobile-specific site, or using the slightly more familiar Bushido technique to deliver sites optimised for device type and viewport size, but either way our focus was on devices. A site was optimised for either a mobile phone or a desktop.

Responsive web design brought us back to pre-table layout fluid sites that expanded or contracted to fit the viewport. This was a big difference to get our heads around when we were so used to designing for fixed-width layouts. Suddenly, an element could be any width or, at least, we needed to consider its maximum and minimum widths. Pixel perfection, while pretty, became wholly unrealistic, and a whole load of designers who prided themselves in detailed and precise designs got a bit scared.

Hanging on to our previous processes and typical deliverables led us to continue to optimise our sites for particular devices and provide pixel-perfect mockups for those device widths.

With all this we were concentrating on devices, not content, deliverables and not process, and making assumptions about users and their devices based on nothing but the width of the viewport.

I don’t think this is a crime, I think it was inevitable.

We can be up to date with our principles and ideals, but it’s never as easy in practice. That’s why it’s more important than ever to share our successful techniques and processes. Let’s drag each other into modern web design.

Design systems: the principles

What are design systems?

A visual design system is built out of the core components of typography, layout, shape or form, and colour. When considering the design of a whole product, a design system should also include patterns in user flow, content strategy, copy, and tone of voice. These concepts, design decisions or rules, created around the core components are used consistently across your product to create a cohesive feel, whether it’s from one element to another, page to page, or viewport width to viewport width.

Responsive design is one of the most important considerations in the components of a design system. For each component, you must decide what will unite the design across the viewports to maintain that consistent feel, and what parts of the design will differentiate in order to provide a flexible and optimal experience for different viewport sizes.

Components you might keep the same across viewports


	typeface
	base unit
	colour
	shape/form


Components you might differentiate across viewports


	grids
	layout
	font size
	measure (line length)
	leading (line height)


Content: it must always be the same

The focus of a design system is the optimum display of content. As Mark Boulton put it, designing “content out, not canvas in.” Chris Armstrong puts the emphasis on not designing for viewports but for content – “we need to build on what we do know: content.” In order to do this, we must share the same content across all devices and focus on how best to display and represent content through design system components.

The practical: core visual components

Typography first

When you work with a lot of text content, typography is the easiest way to set the visual tone of the design across all viewport widths. It’s likely that you’ll choose one or two typefaces to use across the whole system, but you might change the most legible font size, balanced with the most comfortable measure, as the viewport width changes.

Where typography meets layout

The unit on which you choose to base the grid and layout design, font sizes and leading could be based on the typeface, an optimal reading size, or something more arbitrary. Sometimes I’ll choose a unit based on multiples of ten because it makes the maths in the CSS easier. Tim Brown suggests trying a modular scale. Chris Armstrong suggests basing it on your ideal measure, or the width of a fixed item of content such as an ad unit.

Grids and layouts

Sensible grid design can be a flexible yet solid foundation for your design system layout component. But you must be wary in responsive design that a grid might not work across all widths: even four columns could make for very cramped content and one-word measures on smaller screens.

Maybe the grid columns are something you differentiate across widths, but you can keep the concept of the grid consistent. If the content has blocks in groups of three, you might decide on a three-column grid which folds down to one column for narrow viewports. If the grid focuses on the idea of symmetry and has a four-column grid on larger viewports, it might fold down to two columns for narrower viewports. These consistencies may seem subtle, not at all obvious to many except the designer, but it’s all these little constants and patterns across the whole of the design system that makes design decisions easier to make (as they adhere to the guiding concepts of your system), and give the product a uniform feel no matter what the device.

Shape or form

The shape or form components are concepts you already use in fixed-width web design for a strong, consistent look and feel. 

Since CSS border-radius became widely supported by browsers, a lot of designs feature circle themes. These are very distinctive and can be used across viewport widths giving them the same united feel, even if they’re not used in the same way. This could also apply to border styles, consistent shadows and any number of decorative details and textures. These are the elements that make up the shape or form of a design system.

Colour

Colour is the most basic way to reinforce a brand and unite experiences across viewports. The same hex colour used system-wide is instantly recognisable, no matter what the viewport width.

The process

While using a design system isn’t necessarily attached to any particular process, it does lend itself to some process ideals.

Detaching design considerations from viewport widths

A design system allows you to focus separately on the components that make up the system, disconnecting the look and feel from the layout. This helps prevent us getting stuck in the rut of the Apple breakpoints (brilliantly coined by Simon Foster) of mobile, tablet and desktop. It also forces us to design for variation in viewport experiences side by side, not one after the other.

Design in the browser

I can’t start off designing in the browser – it just doesn’t seem to bring out my creative side (and I’m incredibly envious of you if you can; I just have to start on paper) – but static mock-ups aren’t the only alternative. Style guides and style tiles are perfect for expressing the concepts of your design system. Pattern libraries could also work well.

Mock-ups and breakpoints

At some point, whether it’s to test your system ideas, or because a client needs help visualising how your system might work, you may end up producing some static mock-ups. It’s not the end of the world, but you must ensure that these consider all the viewports, not just those of the iDevices, or even the devices currently on the market. You need to decide the breakpoints where the states of your design change. The blocks within your content will always have optimum points for their display (based on their hierarchy, density, width, or type of interaction) and so your breakpoints should be based around these points.

These are probably the ideal points at which to produce static mockups; treat them as snapshots. They’re not necessarily mock-ups, so much as a way of capturing how your design system would be interpreted when frozen at that particular viewport width.

The future

Creating design systems will give us the flexibility we need for working with the unknown devices of the future. It may be a change in process, but it shouldn’t be too much of a difference in thinking. The pioneers in responsive design have a hard job. Some of these problems may have already been solved in other technologies or industries, but it’s up to the pioneers to find those connections and help us formulate solutions and standards that will make responsive design the best it can possibly be. We need to keep experimenting and communicating, particularly in the area of design, as good user experiences are the true sign of whether our products are a success.",2012,Laura Kalbag,laurakalbag,2012-12-12T00:00:00+00:00,https://24ways.org/2012/design-systems/,design
83,Cut Copy Paste,"Long before I got into this design thing, I was heavily into making my own music inspired by the likes of Coldcut and Steinski. I would scour local second-hand record shops in search of obscure beats, loops and bits of dialogue in the hope of finding that killer sample I could then splice together with other things to make a huge hit that everyone would love. While it did eventually lead to a record contract and getting to release a few 12″ singles, ultimately I knew I’d have to look for something else to pay the bills.

I may not make my own records any more, but the approach I took back then – finding (even stealing) things, cutting and pasting them into interesting combinations – is still at the centre of how I work, only these days it’s pretty much bits of code rather than bits of vinyl. Over the years I’ve stored these little bits of code (some I’ve found, some I’ve created myself) in Evernote, ready to be dialled up whenever I need them. 

So when Drew got in touch and asked if I’d like to do something for this year’s 24 ways I thought it might be kind of cool to share with you a few of these snippets that I find really useful. Think of these as a kind of coding mix tape; but remember – don’t just copy as is: play around, combine and remix them into other wonderful things. 

Some of this stuff is dirty; some of it will make hardcore programmers feel ill. For those people, remember this – while you were complaining about the syntax, I made something.

Create unique colours

Let’s start right away with something I stole. Well, actually it was given away at the time by Matt Biddulph who was then at Dopplr before Nokia destroyed it. Imagine you have thousands of words and you want to assign each one a unique colour. Well, Matt came up with a crazily simple but effective way to do that using an MD5 hash. Just encode said word using an MD5 hash, then take the first six characters of the string you get back to create a hexadecimal colour representation. 

I can’t guarantee that it will be a harmonious colour palette, but it’s still really useful. The thing I love the most about this technique is the left-field thinking of using an encryption system to create colours! Here’s an example using JavaScript:

// requires the MD5 library available at http://pajhome.org.uk/crypt/md5

  function MD5Hex(str){
    result = MD5.hex(str).substring(0, 6);
    return result;
  }

Make something breathe using a sine wave

I never paid attention in school, especially during double maths. As a matter of fact, the only time I received corporal punishment – several strokes of the ruler – was in maths class. Anyway, if they had shown me then how beautiful mathematics actually is, I might have paid more attention. Here’s a little example of how a sine wave can be used to make something appear to breathe. 

I recently used this on an Arduino project where an LED ring surrounding a button would gently breathe. Because of that it felt much more inviting. I love mathematics.

for(int i = 0; i<360; i++){    
  float rad = DEG_TO_RAD * i;
  int sinOut = constrain((sin(rad) * 128) + 128, 0, 255);
  analogWrite(LED, sinOut);
  delay(10);   
}

Snap position to grid

This is so elegant I love it, and it was shown to me by Gary Burgess, or Boom Boom as myself and others like to call him. It snaps a position, in this case the X-position, to a grid. Just define your grid size (say, twenty pixels) and you’re good.

snappedXpos = floor( xPos / gridSize) * gridSize;

Calculate the distance between two objects

For me, interaction design is about the relationship between two objects: you and another object; you and another person; or simply one object to another. How close these two things are to each other can be a handy thing to know, allowing you to react to that information within your design. Here’s how to calculate the distance between two objects in a 2-D plane:

deltaX = round(p2.x-p1.x);
deltaY = round(p2.y-p1.y);
diff = round(sqrt((deltaX*deltaX)+(deltaY*deltaY)));

Find the X- and Y-position between two objects

What if you have two objects and you want to place something in-between them? A little bit of interruption and disruption can be a good thing. This small piece of code will allow you to place an object in-between two other objects:

// set the position: 0.5 = half-way	

float position = 0.5;
float x = x1 + (x2 - x1) *position;  
float y = y1 + (y2 - y1) *position;  

Distribute objects equally around a circle 	

More fun with maths, this time adding cosine to our friend sine. Let’s say you want to create a circular navigation of arbitrary elements (yeah, Jakob, you heard), or you want to place images around a circle. Well, this piece of code will do just that. You can adjust the size of the circle by changing the distance variable and alter the number of objects with the numberOfObjects variable. Example below is for use in Processing.

// Example for Processing available for free download at processing.org

void setup() {

  size(800,800);
  int numberOfObjects = 12;
  int distance = 100;
  float inc = (TWO_PI)/numberOfObjects;
  float x,y;
  float a = 0;

  for (int i=0; i < numberOfObjects; i++) {
    x = (width/2) + sin(a)*distance;
    y = (height/2) + cos(a)*distance;
    ellipse(x,y,10,10);
    a += inc;

  }
}

Use modulus to make a grid

The modulus operator, represented by %, returns the remainder of a division. Fallen into a coma yet? Hold on a minute – this seemingly simple function is very powerful in lots of ways. At a simple level, you can use it to determine if a number is odd or even, great for creating alternate row colours in a table for instance:

boolean checkForEven(numberToCheck) {
  if (numberToCheck % 2 == 0) 
    return true;
  } else {
    return false; 
  }
}

That’s all well and good, but here’s a use of modulus that might very well blow your mind. Construct a grid with only a few lines of code. Again the example is in Processing but can easily be ported to any other language.

void setup() {

size(600,600);
int numItems = 120;
int numOfColumns = 12;
int xSpacing = 40;
int ySpacing = 40;
int totalWidth = xSpacing*numOfColumns;

for (int i=0; i < numItems; i++) {

ellipse(floor((i*xSpacing)%totalWidth),floor((i*xSpacing)/totalWidth)*ySpacing,10,10);

}
}

Not all the bits of code I keep around are for actual graphical output. I also have things that are very utilitarian, but which I still consider part of the design process. Here’s a couple of things that I’ve found really handy lately in my design workflow. They may be a little specific, but I hope they demonstrate that it’s not about working harder, it’s about working smarter. 

Merge CSV files into one file

Recently, I’ve had to work with huge – about 1GB – CSV text files that I then needed to combine into one master CSV file so I could then process the data. Opening up each text file and then copying and pasting just seemed really dumb, not to mention slow, so I thought there must be a better way. After some Googling I found this command line script that would combine .txt files into one file and add a new line after each:  

awk 1 *.txt > finalfile.txt

But that wasn’t what I was ideally after. I wanted to merge the CSV files, keeping the first row of the first file (the column headings) and then ignore the first row of subsequent files. Sure enough I found the answer after some Googling and it worked like a charm. Apologies to the original author but I can’t remember where I found it, but you, sir or madam, are awesome. Save this as a shell script:

FIRST=

for FILE in *.csv
  do
    exec 5<""$FILE"" # Open file
    read LINE <&5 # Read first line
      [ -z ""$FIRST"" ] && echo ""$LINE"" # Print it only from first file
      FIRST=""no""

      cat <&5 # Print the rest directly to standard output
      exec 5<&- # Close file
      # Redirect stdout for this section into file.out 

done > file.out

Create a symbolic link to another file or folder

Oftentimes, I’ll find myself hunting through a load of directories to load a file to be processed, like a CSV file. Use a symbolic link (in the Terminal) to place a link on your desktop or wherever is most convenient and it’ll save you loads of time. Especially great if you’re going through a Java file dialogue box in Processing or something that doesn’t allow the normal Mac dialog box or aliases.

cd /DirectoryYouWantShortcutToLiveIn
ln -s /Directory/You/Want/ShortcutTo/ TheShortcut

You can do it, in the mix

I hope you’ve found some of the above useful and that they’ve inspired a few ideas here and there. Feel free to tell me better ways of doing things or offer up any other handy pieces of code. Most of all though, collect, remix and combine the things you discover to make lovely new things.",2012,Brendan Dawes,brendandawes,2012-12-17T00:00:00+00:00,https://24ways.org/2012/cut-copy-paste/,code
95,Giving Content Priority with CSS3 Grid Layout,"Browser support for many of the modules that are part of CSS3 have enabled us to use CSS for many of the things we used to have to use images for. The rise of mobile browsers and the concept of responsive web design has given us a whole new way of looking at design for the web. However, when it comes to layout, we haven’t moved very far at all. We have talked for years about separating our content and source order from the presentation of that content, yet most of us have had to make decisions on source order in order to get a certain visual layout. 

Owing to some interesting specifications making their way through the W3C process at the moment, though, there is hope of change on the horizon. In this article I’m going to look at one CSS module, the CSS3 grid layout module, that enables us to define a grid and place elements on to it. This article comprises a practical demonstration of the basics of grid layout, and also a discussion of one way in which we can start thinking of content in a more adaptive way.

Before we get started, it is important to note that, at the time of writing, these examples work only in Internet Explorer 10. CSS3 grid layout is a module created by Microsoft, and implemented using the -ms prefix in IE10. My examples will all use the -ms prefix, and not include other prefixes simply because this is such an early stage specification, and by the time there are implementations in other browsers there may be inconsistencies. The implementation I describe today may well change, but is also there for your feedback.

If you don’t have access to IE10, then one way to view and test these examples is by signing up for an account with Browserstack – the free trial would give you time to have a look. I have also included screenshots of all relevant stages in creating the examples.

What is CSS3 grid layout?

CSS3 grid layout aims to let developers divide up a design into a grid and place content on to that grid. Rather than trying to fabricate a grid from floats, you can declare an actual grid on a container element and then use that to position the elements inside. Most importantly, the source order of those elements does not matter. 

Declaring a grid

We declare a grid using a new value for the display property: display: grid. As we are using the IE10 implementation here, we need to prefix that value: display: -ms-grid;.

Once we have declared our grid, we set up the columns and rows using the grid-columns and grid-rows properties.

.wrapper {
    display: -ms-grid;
    -ms-grid-columns: 200px 20px auto 20px 200px;
    -ms-grid-rows: auto 1fr;
}

In the above example, I have declared a grid on the .wrapper element. I have used the grid-columns property to create a grid with a 200 pixel-wide column, a 20 pixel gutter, a flexible width auto column that will stretch to fill the available space, another 20 pixel-wide gutter and a final 200 pixel sidebar: a flexible width layout with two fixed width sidebars. Using the grid-rows property I have created two rows: the first is set to auto so it will stretch to fill whatever I put into it; the second row is set to 1fr, a new value used in grids that means one fraction unit. In this case, one fraction unit of the available space, effectively whatever space is left.

Positioning items on the grid

Now I have a simple grid, I can pop items on to it. If I have a <div> with a class of .main that I want to place into the second row, and the flexible column set to auto I would use the following CSS:

.content {
    -ms-grid-column: 3;
    -ms-grid-row: 2;
    -ms-grid-row-span: 1;
}

If you are old-school, you may already have realised that we are essentially creating an HTML table-like layout structure using CSS. I found the concept of a table the most helpful way to think about the grid layout module when trying to work out how to place elements.

Creating grid systems

As soon as I started to play with CSS3 grid layout, I wanted to see if I could use it to replicate a flexible grid system like this fluid 16-column 960 grid system.

I started out by defining a grid on my wrapper element, using fractions to make this grid fluid.

.wrapper {	 
    width: 90%;
    margin: 0 auto 0 auto;
    display: -ms-grid;
    -ms-grid-columns: 1fr (4.25fr 1fr)[16];
    -ms-grid-rows: (auto 20px)[24];
}

Like the 960 grid system I was using as an example, my grid starts with a gutter, followed by the first actual column, plus another gutter repeated sixteen times. What this means is that if I want to span two columns, as far as the grid layout module is concerned that is actually three columns: two wide columns, plus one gutter. So this needs to be accounted for when positioning items.

I created a CSS class for each positioning option: column position; rows position; and column span. For example:

.grid1 {-ms-grid-column: 2;} /* applying this class positions an item in the first column (the gutter is column 1) */
.grid2 {-ms-grid-column: 4;} /* 2nd column - gutter|column 1|gutter */
.grid3 {-ms-grid-column: 6;} /* 3rd column - gutter|column 1|gutter|column2|gutter */

.row1 {-ms-grid-row:1;}
.row2 {-ms-grid-row:3;}
.row3 {-ms-grid-row:5;}

.colspan1 {-ms-grid-column-span:1;}
.colspan2 {-ms-grid-column-span:3;}
.colspan3 {-ms-grid-column-span:5;}

I could then add multiple classes to each element to set the position on on the grid.



This then gives me a replica of the fluid grid using CSS3 grid layout. To see this working fire up IE10 and view Example 1.

This works, but…

This worked, but isn’t ideal. I considered not showing this stage of my experiment – however, I think it clearly shows how the grid layout module works and is a useful starting point. That said, it’s not an approach I would take in production. First, we have to add classes to our markup that tie an element to a position on the grid. This might not be too much of a problem if we are always going to maintain the sixteen-column grid, though, as I will show you that the real power of the grid layout module appears once you start to redefine the grid, using different grids based on media queries. If you drop to a six-column layout for small screens, positioning items into column 16 makes no sense any more.

Calculating grid position using LESS

As we’ve seen, if you want to use a grid with main columns and gutters, you have to take into account the spacing between columns as well as the actual columns. This means we have to do some calculating every time we place an item on the grid. In my example above I got around this by creating a CSS class for each position, allowing me to think in sixteen rather than thirty-two columns. But by using a CSS preprocessor, I can avoid using all the classes yet still think in main columns.

I’m using LESS for my example. My simple grid framework consists of one simple mixin.

.position(@column,@row,@colspan,@rowspan) {
    -ms-grid-column: @column*2;
    -ms-grid-row: @row*2-1;
    -ms-grid-column-span: @colspan*2-1;
    -ms-grid-row-span: @rowspan*2-1;
}

My mixin takes four parameters: column; row; colspan; and rowspan. So if I wanted to place an item on column four, row three, spanning two columns and one row, I would write the following CSS:

.box {
    .position(4,3,2,1);
}

The mixin would return:

.box {
    -ms-grid-column: 8;
    -ms-grid-row: 5;
    -ms-grid-column-span: 3;
    -ms-grid-row-span: 1;
}

This saves me some typing and some maths. I could also add other prefixed values into my mixin as other browsers started to add support.

We can see this in action creating a new grid. Instead of adding multiple classes to each element, I can add one class; that class uses the mixin to create the position. I have also played around with row spans using my mixin and you can see we end up with a quite complicated arrangement of boxes. Have a look at example two in IE10. I’ve used the JavaScript LESS parser so that you can view the actual LESS that I use. Note that I have needed to escape the -ms prefixed properties with ~"""" to get LESS to accept them.



This is looking better. I don’t have direct positioning information on each element in the markup, just a class name – I’ve used grid(x), but it could be something far more semantic. We can now take the example a step further and redefine the grid based on screen width.

Media queries and the grid

This example uses exactly the same markup as the previous example. However, we are now using media queries to detect screen width and redefine the grid using a different number of columns depending on that width.

I start out with a six-column grid, defining that on .wrapper, then setting where the different items sit on this grid:

.wrapper {	 
    width: 90%;
    margin: 0 auto 0 auto;
    display: ~""-ms-grid""; /* escaped for the LESS parser */
    -ms-grid-columns: ~""1fr (4.25fr 1fr)[6]""; /* escaped for the LESS parser */
    -ms-grid-rows: ~""(auto 20px)[40]""; /* escaped for the LESS parser */
}
.grid1 { .position(1,1,1,1); } 
.grid2 { .position(2,1,1,1); } 
/* ... see example for all declarations ... */



Using media queries, I redefine the grid to nine columns when we hit a minimum width of 700 pixels.

@media only screen and (min-width: 700px) {
.wrapper {
    -ms-grid-columns: ~""1fr (4.25fr 1fr)[9]"";
    -ms-grid-rows: ~""(auto 20px)[50]"";
}
.grid1 { .position(1,1,1,1); } 
.grid2 { .position(2,1,1,1); } 
/* ... */
}



Finally, we redefine the grid for 960 pixels, back to the sixteen-column grid we started out with.

@media only screen and (min-width:  940px) {
.wrapper {	 
    -ms-grid-columns:~"" 1fr (4.25fr 1fr)[16]"";
    -ms-grid-rows:~"" (auto 20px)[24]"";
}
.grid1 { .position(1,1,1,1); } 
.grid2 { .position(2,1,1,1); } 
/* ... */
}

If you view example three in Internet Explorer 10 you can see how the items reflow to fit the window size. You can also see, looking at the final set of blocks, that source order doesn’t matter. You can pick up a block from anywhere and place it in any position on the grid.

Laying out a simple website

So far, like a toddler on Christmas Day, we’ve been playing with boxes rather than thinking about what might be in them. So let’s take a quick look at a more realistic layout, in order to see why the CSS3 grid layout module can be really useful. At this time of year, I am very excited to get out of storage my collection of odd nativity sets, prompting my family to suggest I might want to open a museum. Should I ever do so, I’ll need a website, and here is an example layout.



As I am using CSS3 grid layout, I can order my source in a logical manner. In this example my document is as follows, though these elements could be in any order I please:

<div class=""wrapper"">
  <div class=""welcome"">
  ...
  </div>
  <article class=""main"">
  ...
  </article>
  <div class=""info"">
  ...
  </div>
  <div class=""ads"">
  ...
  </div>
</div>

For wide viewports I can use grid layout to create a sidebar, with the important information about opening times on the top righ,t with the ads displayed below it. This creates the layout shown in the screenshot above.

@media only screen and (min-width:  940px) {
  .wrapper {	 
    -ms-grid-columns:~"" 1fr (4.25fr 1fr)[16]"";
    -ms-grid-rows:~"" (auto 20px)[24]"";
  }
  .welcome {
    .position(1,1,12,1);
    padding: 0 5% 0 0;
  }
  .info {
    .position(13,1,4,1);
    border: 0;
    padding:0;
   }
  .main {
    .position(1,2,12,1);
    padding: 0 5% 0 0;
  }  
  .ads {
    .position(13,2,4,1);
    display: block;
    margin-left: 0;
  }
}

In a floated layout, a sidebar like this often ends up being placed under the main content at smaller screen widths. For my situation this is less than ideal. I want the important information about opening times to end up above the main article, and to push the ads below it. With grid layout I can easily achieve this at the smallest width .info ends up in row two and .ads in row five with the article between.

.wrapper {	 
  display: ~""-ms-grid"";
  -ms-grid-columns: ~""1fr (4.25fr 1fr)[4]"";
  -ms-grid-rows: ~""(auto 20px)[40]"";
}
.welcome {
    .position(1,1,4,1);
}
.info {
    .position(1,2,4,1);
    border: 4px solid #fff;
    padding: 10px;
}
.content {
    .position(1,3,4,5);
}
.main {
    .position(1,3,4,1);
}
.ads {
    .position(1,4,4,1);
}



Finally, as an extra tweak I add in a breakpoint at 600 pixels and nest a second grid on the ads area, arranging those three images into a row when they sit below the article at a screen width wider than the very narrow mobile width but still too narrow to support a sidebar. 

@media only screen and (min-width:  600px) {
  .ads {
    display: ~""-ms-grid"";
    -ms-grid-columns: ~""20px 1fr 20px 1fr 20px 1fr"";
    -ms-grid-rows: ~""1fr"";
    margin-left: -20px;
  }
  .ad:nth-child(1) {
    .position(1,1,1,1);
  }
  .ad:nth-child(2) {
    .position(2,1,1,1);
  }
  .ad:nth-child(3) {
    .position(3,1,1,1);
  }
}

View example four in Internet Explorer 10.



This is a very simple example to show how we can use CSS grid layout without needing to add a lot of classes to our document. It also demonstrates how we can mainpulate the content depending on the context in which the user is viewing it.

Layout, source order and the idea of content priority

CSS3 grid layout isn’t the only module that starts to move us away from the issue of visual layout being linked to source order. However, with good support in Internet Explorer 10, it is a nice way to start looking at how this might work. If you look at the grid layout module as something to be used in conjunction with the flexible box layout module and the very interesting CSS regions and exclusions specifications, we have, tantalizingly on the horizon, a powerful set of tools for layout.

I am particularly keen on the potential separation of source order from layout as it dovetails rather neatly into something I spend a lot of time thinking about. As a CMS developer, working on larger scale projects as well as our CMS product Perch, I am interested in how we better enable content editors to create content for the web. In particular, I search for better ways to help them create adaptive content; content that will work in a variety of contexts rather than being tied to one representation of that content.

If the concept of adaptive content is new to you, then Karen McGrane’s presentation Adapting Ourselves to Adaptive Content is the place to start. Karen talks about needing to think of content as chunks, that might be used in many different places, displayed differently depending on context.

I absolutely agree with Karen’s approach to content. We have always attempted to move content editors away from thinking about creating a page and previewing it on the desktop. However at some point content does need to be published as a page, or a collection of content if you prefer, and bits of that content have priority. Particularly in a small screen context, content gets linearized, we can only show so much at a time, and we need to make sure important content rises to the top. In the case of my example, I wanted to ensure that the address information was clearly visible without scrolling around too much. Dropping it with the entire sidebar to the bottom of the page would not have been so helpful, though neither would moving the whole sidebar to the top of the screen so a visitor had to scroll past advertising to get to the article.

If our layout is linked to our source order, then enabling the content editor to make decisions about priority is really hard. Only a system that can do some regeneration of the source order on the server-side – perhaps by way of multiple templates – can allow those kinds of decisions to be made. For larger systems this might be a possibility; for smaller ones, or when using an off-the-shelf CMS, it is less likely to be. Fortunately, any system that allows some form of custom field type can be used to pop a class on to an element, and with CSS grid layout that is all that is needed to be able to target that element and drop it into the right place when the content is viewed, be that on a desktop or a mobile device.

This approach can move us away from forcing editors to think visually. At the moment, I might have to explain to an editor that if a certain piece of content needs to come first when viewed on a mobile device, it needs to be placed in the sidebar area, tying it to a particular layout and design. I have to do this because we have to enforce fairly strict rules around source order to make the mechanics of the responsive design work. If I can instead advise an editor to flag important content as high priority in the CMS, then I can make decisions elsewhere as to how that is displayed, and we can maintain the visual hierarchy across all the different ways content might be rendered.

Why frustrate ourselves with specifications we can’t yet use in production?

The CSS3 grid layout specification is listed under the Exploring section of the list of current work of the CSS Working Group. While discussing a module at this stage might seem a bit pointless if we can’t use it in production work, there is a very real reason for doing so. If those of us who will ultimately be developing sites with these tools find out about them early enough, then we can start to give our feedback to the people responsible for the specification. There is information on the same page about how to get involved with the disussions.

So, if you have a bit of time this holiday season, why not have a play with the CSS3 grid layout module? I have outlined here some of my thoughts on how grid layout and other modules that separate layout from source order can be used in the work that I do. Likewise, wherever in the stack you work, playing with and thinking about new specifications means you can think about how you would use them to enhance your work. Spot a problem? Think that a change to the specification would improve things for a specific use case? Then you have something you could post to www-style to add to the discussion around this module.

All the examples are on CodePen so feel free to play around and fork them.",2012,Rachel Andrew,rachelandrew,2012-12-18T00:00:00+00:00,https://24ways.org/2012/css3-grid-layout/,code
87,Content Planning Demystified,"The first thing you learn as a junior editor is that you can’t do everything yourself. You must rely on someone else to do at least part of what must be done: the long-range planning, the initial drafting or shooting or recording, the editing, the production, the final polish. All of those pieces of work that belong to someone else take quite a lot of time — days, weeks, sometimes months. If you’re the sort of person who wrote college term papers the night before they were due, this can come as a bit of a shock. To my twenty-two-year-old self, it certainly did. 

It turns out that the only real way to avoid a trainwreck with editorial work is to get ahead of the trouble, line everything up carefully, and leave oodles of room for all the pieces to connect on time. The same is true of content strategy, content planning, and just about everything to do with content on the web, except for the writing itself — and that, too, usually takes far longer than anyone expects. If you’re not a professional editor and you suddenly find yourself dealing with content creation, you’re almost certainly going to underestimate the time and effort involved, or to skip something important in the planning process that pops up to bite you later. 

Without good content, it doesn’t matter how well designed or coded your web project is, because it won’t be doing the thing it’s meant to do. And even if content is far from your specialty, you may well end up being the only one willing to coordinate it far enough in advance to avoid a chaotic ending. Whether you’re hiring writers and editors for a big project, working with a small client, or coaxing some editorial help out of a co-worker, getting the planning work done correctly — and ahead of time — will allow you to orchestrate a glorious ballet of togetherness, instead of feverishly scraping together something to put on your site when the deadline looms. So get out the graph paper and the pocket protector, because we’re going to go Full Nerd on this problem.

Know your poison

Anyone who’s seen a project delayed for six months by content trouble, or derailed by content that’s bland and unhelpful, knows this stuff can make you feel like a dead sock. To get ahead of the problem, you’re going to have to learn to spot common problems and plan your way around them. On web projects without a dedicated editorial lead, you’re likely to encounter content that is:


	Useless – Content that doesn’t serve your readers’ needs in some way is pointless. And because it takes up your time and crowds out genuinely helpful things, it’s actually damaging. The logic is simple: you can make content that’s all about you, and that serves your stated messaging goals, but if no one is motivated to read it, it’s a waste of everyone’s time.
	Badly written – When you publish articles or instructions or other content that is too stiffly formal, overly wordy, hard to understand, offensive, unintentionally cheesy, or otherwise off in tone or style, you’re doing two things. First, you’re weakening the information you’re trying to convey by making it obscure or annoying. Second — and this one is even more damaging — you’re demonstrating bad taste. When you get the cultural elements of publishing wrong, you encourage your readers to believe that you either don’t understand them or don’t care about getting it wrong.
	Gooey – Content strategists have been talking about structured content (that’s chunks versus blobs) for years. If you’re publishing more than a few dozen pages without thinking through the structure of your content, you’re probably missing a chance to improve your long-term efficiency. If you’re publishing more than a couple of thousand pages without taking care of your content structure, you’re probably doing a lot more manual wrangling (or cumbersome CMS work) than you need to be, especially when it comes to cross-platform publishing.
	Unregulated – If you’re not tracking what works and what doesn’t — and especially if you don’t know what “works” means for your project or organization — you’re almost certainly getting worse results than you should be, for more work.
	Overabundant – As demonstrated by the cinnamon challenge, too much of a delicious thing can be a giant and publicly embarrassing disaster. For most projects and organizations, if you’re making more stuff than your readers can handle, or if you’re spreading your creative and editorial resources too thinly, that’s bad. Spammers, content farms, and barrel-bottom tabloids have their own special math, the side effects of which include insomnia, irritability, and crying in traffic while silently mouthing Wilson Phillips lyrics.



Prevent all preventable damage

Once you know what kind of trouble to look for, you can prevent a lot of it by doing some smart planning well before someone starts writing (or recording or shooting video).


	To prevent uselessness: Know your readers and decide what you’re trying to accomplish — with your website as a whole, and with each piece of content, always. Once you know what you’re trying to achieve, you can evaluate your work as you go to make sure that it’s actually doing the right thing. (I’ve written a lot more about this for A List Apart and in The Elements of Content Strategy.)
	To prevent bad writing: Establish a consistent and appropriate style using examples (and a style guide if you need one), designate an editor, hire good writers, and make time for quality control. Kate Kiefer’s style guide for MailChimp is a superb example of style-wrangling that everyone can use.
	To prevent repulsive goo: Give your content as much structure as possible, and know how structure relates to your entire publishing ecosystem, including all those mobile devices. Sara Wachter-Boettcher’s Content Everywhere and Karen McGrane’s Content Strategy for Mobile offer brilliant yet friendly introductions to the wide world of structured content.
	To prevent unregulated chaos: Measure everything that matters to your project, your client, your organization, and especially your readers — not generic measures of someone else’s success. Measure it all regularly. Be disciplined. Adjust at regular intervals. Rick Allen’s series on content strategy analytics is an excellent place to begin (part one; part two).
	To prevent overabundance: Stop trying to do everything and focus on giving your readers just a few things they want and genuinely need. Don’t establish a schedule your writers might not be able to keep, and focus on differentiating yourself with quality, not quantity. (And while you’re at it, scratch the auto-posting to social networks and the cross-posting between them. It’s about as engaging as an automated phone system.)


At a slightly higher level, pick the right content person (or team) for the work. If you really only need a few pages of copy, find a smart writer who does good work for multi-platform readers. If you’re slinging tens of thousands of pages of content, get someone with field experience in high-level editorial planning and the ability to turn blobs into chunks and melted goo into Legos. If you’re starting a project that involves making a lot of content over time, bring in someone with journalism experience (or get your client to do so). 

“But wait!” you may say. “I’m not hiring anyone. I have to do this all myself.” That’s not uncommon at all. The bad news is, you have to learn a bunch of stuff. The good news is, you get to learn a bunch of awesome stuff. Figure out what the project needs, just as though you were going to hire someone, and then give yourself time to get up to speed. If it’s a really complicated project, you’re probably going to have trouble unless you eventually get professional help. But if it’s small and you can do it in steps, you can certainly do much better by giving yourself a plan and working on the things that matter most.


Plan for the marathon, not the sprint

Launching with awesome content is a tiny fraction of a victory, which is why it’s so important that your content not be gooey or unregulated. It also means that if you don’t plan for a realistic publication schedule, you are going to slam into reality in a really unpleasant way not too long after you’ve begun. If you’re asking people to make words (or videos or whatever) for you, they’re going to have to do less of something else, so plan for that beforehand. 

And while you’re at it, unless publishing is your core business, ditch the feed-the-beast plan that leads to fluffy blog posts and spiritless, unhelpful social media content. It’s antisocial for your reading community, offers short-term gains at best, and will burn you out or lower your standards until you don’t even know you’re doing lousy work. Good content is expensive, no matter how you do it, but spreading yourself too thin is a much worse investment than doing a smaller thing well and gradually building up a body of superb content that people want to share and keep and return to.",2012,Erin Kissane,erinkissane,2012-12-20T00:00:00+00:00,https://24ways.org/2012/content-planning-demystified/,content
77,Colour Accessibility,"Here’s a quote from Josef Albers:

In visual perception a colour is almost never seen as it really is[…] This fact makes colour the most relative medium in art.Josef Albers, Interaction of Color, 1963

Albers was a German abstract painter and teacher, and published a very famous course on colour theory in 1963. Colour is very relative — not just in the way that it appears differently across different devices due to screen quality and colour management, but it can also be seen differently by different people — something we really need to be more mindful of when designing.

What is colour blindness?

Colour blindness very rarely means that you can’t see any colour at all, or that people see things in greyscale. It’s actually a decreased ability to see colour, or a decreased ability to tell colours apart from one another. 

How does it happen?

Inside the typical human retina, there are two types of receptor cells — rods and cones. Rods are the cells that allow us to see dark and light, and shape and movement. Cones are the cells that allow us to perceive colour. There are three types of cones, each responsible for absorbing blue, red, and green wavelengths in the spectrum.

Problems with colour vision occur when one or more of these types of cones are defective or absent entirely, and these problems can either be inherited through genetics, or acquired through trauma, exposure to ultraviolet light, degeneration with age, an effect of diabetes, or other factors.

Colour blindness is a sex-linked trait and it’s much more common in men than in women. The most common type of colour blindness is called deuteranomaly which occurs in 7% of males, but only 0.5% of females. That’s a pretty significant portion of the population if you really stop and think about it — we can’t ignore this demographic.

What does it look like?

People with the most common types of colour blindness, like protanopia and deuteranopia, have difficulty discriminating between red and green hues. There are also forms of colour blindness like tritanopia, which affects perception of blue and yellow hues. Below, you can see what a colour wheel might look like to these different people.



What can we do?

Here are some things you can do to make your websites and apps more accessible to people with all types of colour blindness.

Include colour names and show examples

One of the most common annoyances I’ve heard from people who are colour-blind is that they often have difficulty purchasing clothing and they will sometimes need to ask another person for a second opinion on what the colour of the clothing might actually be. While it’s easier to shop online than in a physical store, there are still accessibility issues to consider on shopping websites.

Let’s say you’ve got a website that sells T-shirts. If you only show a photo of the shirt, it may be impossible for a person to tell what colour the shirt really is. For clarification, be sure to reference the name of the colour in the description of the product.



United Pixelworkers does a great job of following this rule. The St. John’s T-shirt has a quirky palette inspired by the unofficial pink, white and green Newfoundland flag, and I can imagine many people not liking it.

Another common problem occurs when a colour filter has been added to a product search. Here’s an example from a clothing website with unlabelled colour swatches, and how that might look to someone with deuteranopia-type colour blindness.



The colour search filter below, from the H&M website, is much better since it uses names instead.



At first glance, Urban Outfitters also uses unlabelled colour swatches on product pages (below), but on closer inspection, the colour name is displayed on hover. This isn’t an ideal solution, because although it’ll work on a desktop browser, it won’t work on a touchscreen device where hovering isn’t an option. 



Using overly fancy colour names, like the ones you might find labelling high-end interior paint can be just as confusing as not using a colour name at all. Names like grape instead of purple don’t really give the viewer any useful information about what the colour actually is on a colour wheel. Is grape supposed to be purple, or could it refer to red grapes or even green? Stick with hue names as much as possible.

Avoid colour-specific instructions

When designing forms, avoid labelling required fields only with coloured text. It’s safer to use a symbol cue like the asterisk which is colour-independent. 



A similar example would be directing a user to click a green button to purchase a product. Label your buttons clearly and reference them in the site copy by function, not colour, to avoid confusion.

Don’t rely on colour coding

Designing accessible maps and infographics can be much more challenging. 

Don’t rely on colour coding alone — try to use a combination of colour and texture or pattern, along with precise labels, and reflect this in the key or legend. Combine a blue background with a crosshatched pattern, or a pink background with a stippled dot — your users will always have two pieces of information to work with.



The map of the London subway system is an iconic image not just in London, but around the world. Unfortunately, it contains some colours that are indistinguishable from each other to a person with a vision problem. This is true not only for the London underground, but also for any other wayfinding system that relies on colour coding as the only key in a legend. 



There are printable versions of the map available online in black and white, using patterns and shades of black and grey that are distinguishable, but the point is that there would be no need for such a map if it were designed with accessibility in mind from the beginning. And, if you’re a person who has a physical disability as well as a vision problem, the “Step-Free” guide map which shows stations is based on the original coloured map. 



Provide alternatives and customization

While it’s best to consider these issues and design your app to be accessible by default, sometimes this might not be possible. Providing alternative styles or allowing users to edit their own colours is a feature to keep in mind.

The developers of the game Faster Than Light created an alternate colour-blind mode and asked for public feedback to make sure that it passed the test. Not much needed to be done, but you can see they added stripes to the red zones and changed some outlines to blue.



iChat is also a good example. Although by default it uses coloured bubbles to indicate a user’s status (available for chat, away or idle, or busy), included in the preferences is a “User Shapes to Indicate Status” option, which changes the shape of the standard circles to green circles, yellow triangles and red squares.



Pay attention to contrast  

Colours that are similar in value but different in hue may be easy to distinguish between for a user with good vision, but a person who suffers from colour blindness may not be able to tell them apart at all. Proofing your work in greyscale is a quick way to tell if there’s enough contrast between the most important information in your design.

Check with a simulator

There are many tools out there for simulating different types of colour blindness, and it’s worth checking your design to catch any potential problems up front. 

One is called Sim Daltonism and it’s available for Mac OS X. It’ll show a pop-up preview next to your cursor and you can choose which type of colour blindness you want to test from a drop-down menu. 



You can also proof for the two most common types of colour blindness right in Photoshop or Illustrator (CS4 and later) while you’re designing. 



The colour contrast check tool from designer and developer Jonathan Snook gives you the option to enter a colour code for a background, and a colour code for text, and it’ll tell you if the colour contrast ratio meets the Web Content Accessibility Guidelines 2.0. You can use the built-in sliders to adjust your colours until they meet the compliant contrast ratios. This is a great tool to test your palette before going live.



For live websites, you can use the accessibility tool called WAVE, which also has a contrast checker. It’s important to keep in mind, though, that while WAVE can identify contrast errors in text, other things can slip through, so a site that passes the test does not automatically mean it’s accessible in reality.

For example, the contrast checker here doesn’t notice that our red link in the introduction isn’t underlined, and therefore could blend into the surrounding paragraph text. 



I know that once I started getting into the habit of checking my work in a simulator, I became more mindful of any potential problem areas and it was easier to avoid them up front. It’s also made me question everything I see around me and it sends red flags off in my head if I think it’s a serious colour blindness fail. Understanding that colour is relative in the planning stages and following these tips will help us make more accessible design for all.",2012,Geri Coady,gericoady,2012-12-04T00:00:00+00:00,https://24ways.org/2012/colour-accessibility/,design
82,Being Prepared To Contribute,"“You’ll figure it out.” The advice my dad gives has always been the same, whether addressing my grade school homework or paying bills after college. If I was looking for a shortcut, my dad wasn’t going to be the one to provide it.

When I was a kid it infuriated the hell out of me, but what I then perceived to be a lack of understanding turned out to be a keystone in my upbringing. As an adult, I realize the value in not receiving outright solutions, but being forced to figure things out. 

Even today, when presented with a roadblock while building for the web, I am temped to get by with the help of the latest grid system, framework, polyfill, or plugin. In and of themselves these resources are harmless, but before I can drop them in, those damn words still echo in the back of my mind: “You’ll figure it out.”

I know that if I blindly implement these tools as drag and drop solutions I fail to understand the intricacies behind how and why they were built; repeatedly using them as shortcuts handicaps my skill set. When I solely rely on the tools of others, my work is at their mercy, leaving me less creative and resourceful, and, thus, less able to contribute to the advancement of our industry and community. 

One of my favorite things about this community is how generous and collaborative it can be. I’ve loved seeing FitVids used all over the web and regularly improved upon at Github. I bet we can all think of a time where implementing a shared resource has benefitted our own work and sanity. Because these resources are so valuable, it’s important that we continue to be a part of the conversation in order to further develop solutions and ideas. It’s easy to assume there’s someone smarter or more up-to-date in any one area, but with a degree of understanding and perspective, we can all participate. 

This open form of collaboration is in our web DNA. After all, its primary purpose was to promote the exchange and development of new ideas.


	Tim Berners-Lee proposed a global hypertext project, to be known as the World Wide Web. Based on the earlier “Enquire” work, it was designed to allow people to work together by combining their knowledge in a web of hypertext documents.


I’m delighted to find that this spirit of collaborative ingenuity is alive and well on the web today. Take the story of Off Canvas as an example. I was at an ATX Dribbble meet up where I met Jason Weaver and chatted to him about his recent work on the responsive layout prototype, Off Canvas. Jason said he came across a post by Luke Wroblewski outlining the idea and saw this:


	If anyone is interested in building a complete example of this approach using responsive Web design techniques, let me know!


From there Luke recounts: 


	We went back and forth on email, with me laying out ideas and Jason doing all the hard work to see if they can be done and improving them bit by bit! Once we got to something we both liked, I wrote up an article explaining things and he hosted the examples.


Luke took the time to clearly outline and diagram his ideas, and Jason responded with a solid proof of concept that has evolved into a tool we all have at our disposal. Victory!

I have also benefitted from comrades who have taken an idea of mine into development. After blogging about some concerns in regards to maintaining hierarchy as media queries are used to shift layouts, Jordan Moore rebounded with some responsive demos where he used flexbox to (re)order content as viewport sizing changes.

Similar stories can be found behind the development of things like FitVids, FitText, and Molten Leading. I love this pattern of collaboration because it involves a fairly specific process:


	Initial idea or prototype is outlined or built, then shared
	Discuss
	Someone develops or improves it, then shares it
	Discuss
	Someone else develops or improves it, then shares it.
	Infinity.


This is what the web looks like when we build it together, and I’d argue that steps 2+ are absolutely crucial. A web where everyone develops their own ideas and tools independent of one another is like a room full of people talking and no one listening. 



The pattern itself mimics a literal web structure, and ideally we’d be able to follow a strand from one idea to the next and so on.

Blessed are the curators

Sometimes those lines aren’t easy to find or follow. Thankfully, there are people who painstakingly log each experiment and index much of what’s out there. Chris Coyier does this with CSS in general, and Brad Frost is doing this for responsive and multi-device design with his Pattern Library. Seriously, take a look at this page and imagine what it would take to find, track and organize the progression of each of these resources yourself. I’d argue that ongoing collections like these are more valuable than the sum of their parts when they are updated regularly as opposed to a top ten tips blog post format.

Here’s my soapbox

Here are a few things I appreciate about how things are shared and contributed online. And yes, I could do way better at all of them myself.


	Concise write-ups: honor others’ time by getting to the point. Not every idea or solution needs two thousand words to convey fully. I love long-form posts, but there’s a time and a place for them.
	Visual aids: if a quick illustration, screenshot, or graphic helps illustrate your point or problem, yes please.


By the way, Luke Wroblewski rules the school on both of these.


	Demo it: host it yourself, or put it on CodePen or JS Bin for others to see.
	Put it on Github: share and improve with the rest of the community. Consider, however, that because someone puts something on Github doesn’t mean they’re forever bound to provide support or instruction.


This isn’t a call for everyone to learn everything all the time, but if you’re curious or interested in something, skip the shortcut and get your hands dirty: sketch, prototype, question, debate, fork, and share. Figuring these things out on our own makes us valuable contributors to the web – the thing that ultimately we’re all trying to figure out together.",2012,Trent Walton,trentwalton,2012-12-03T00:00:00+00:00,https://24ways.org/2012/being-prepared-to-contribute/,process
75,A Harder-Working Class,"Class is only becoming more important. Focusing on its original definition as an attribute for grouping (or classifying) as well as linking HTML to CSS, recent front-end development practices are emphasizing class as a vessel for structured, modularized style packages. These patterns reduce the need for repetitive declarations that can seriously bloat file sizes, and instil human-readable understanding of how the interface, layout, and aesthetics are constructed.

In the next handful of paragraphs, we will look at how these emerging practices – such as object-oriented CSS and SMACSS – are pushing the relevance of class. We will also explore how HTML and CSS architecture can be further simplified, performance can be boosted, and CSS utility sharpened by combining class with the attribute selector.

A primer on attribute selectors

While attribute selectors were introduced in the CSS 2 spec, they are still considered rather exotic. These well-established and well-supported features give us vastly improved flexibility in targeting elements in CSS, and offer us opportunities for smarter markup. With an attribute selector, you can directly style an element based on any of its unique – or uniquely shared – attributes, without the need for an ID or extra classes. Unlike pseudo-classes, pseudo-elements, and other exciting features of CSS3, attribute selectors do not require any browser-specific syntax or prefix, and are even supported in Internet Explorer 7. 

For example, say we want to target all anchor tags on a page that link to our homepage. Where otherwise we might need to manually identify and add classes to the HTML for these specific links, we could simply write:

[href=index.html] {  }

This selector reads: target every element that has an href attribute of “index.html”. 

Attribute selectors are more faceted, though, as they also give us some very simple regular expression-like logic that helps further narrow (or widen) a selector’s scope. In our previous example, what if we wanted to also give indicative styles to any anchor tag linking to an external site? With no way to know what the exact href value would be for every external link, we need to use an expression to match a common aspect of those links. In this case, we know that all external links need to start with “http”, so we can use that as a hook:

[href^=http] {  }

The selector here reads: target every element that has an href attribute that begins with “http” (which will also include “https”). The ^= means “starts with”. There are a few other simple expressions that give us a lot of flexibility in targeting elements, and I have found that a deep understanding of these and other selector types to be very useful.

The class-attribute selector

By matching classes with the attribute selector, CSS can be pushed to accomplish some exciting new feats. What I call a class-attribute selector combines the advantages of classes with attribute selectors by targeting the class attribute, rather than a specific class. Instead of selecting .urgent, you could select [class*=urgent]. The latter may seem like a more verbose way of accomplishing the former, but each would actually match two subtly different groups of elements.

Eric Meyer first explored the possibility of using classes with attribute selectors over a decade ago. While his interest in this technique mostly explored the different facets of the syntax, I have found that using class-attribute selectors can have distinct advantages over either using an attribute selector or a straightforward class selector.

First, let’s explore some of the subtleties of why we would target class before other attributes:


	Classes are ubiquitous. They have been supported since the HTML 4 spec was released in 1999. Newer attributes, such as the custom data attribute, have only recently begun to be adopted by browsers.
	Classes have multiple ways of being targeted. You can use the class selector or attribute selector (.classname or [class=classname]), allowing more flexible specificity than resorting to an ID or !important.
	Classes are already widely used, so adding more classes will usually require less markup than adding more attributes.
	Classes were designed to abstractly group and specify elements, making them the most appropriate attribute for styling using object-oriented methods (as we will learn in a moment).


Also, as Meyer pointed out, we can use the class-attribute selector to be more strict about class declarations. Of these two elements:

<h2 class=""very urgent"">

<h2 class=""urgent"">

…only the second h2 would be selected by [class=urgent], while .urgent would select both. The use of = matches any element with the exact class value of “urgent”. Eric explores these nuances further in his series on attribute selectors, but perhaps more dramatic is the added power that class-attribute selectors can bring to our CSS.

More object-oriented, more scalable and modular

Nicole Sullivan has been pushing abstracted, object-oriented thinking in CSS development for years now. She has shared stacks of knowledge on how behemoth sites have seen impressive gains in maintenance overhead and CSS file sizes by leaning heavier on classes derived from common patterns. Jonathan Snook also speaks, writes and is genuinely passionate about improving our markup by using more stratified and modular class name conventions. With SMACSS, he shows this to be highly useful across sites – both complex and simple – that exhibit repeated design patterns. Sullivan and Snook both push the use of class for styling over other attributes, and many front-end developers are fast advocating such thinking as best practice.

With class-attribute selectors, we can further abstract our CSS, pushing its scalability. In his chapter on modules, Snook gives the example of a .pod class that might represent a certain set of styles. A .pod style set might be used in varying contexts, leading to CSS that might normally look like this:

.pod {  }
form .pod {  }
aside .pod {  }

According to Snook, we can make these styles more portable by targeting more verbose classes, rather than context:

.pod {  }
.pod-form {  }
.pod-sidebar {  }

…resulting in the following HTML:

<div class=""pod"">
<div class=""pod pod-form"">
<div class=""pod pod-sidebar"">

This divorces the <div>’s styles from its context, making it applicable to any situation in which it is needed. The markup is clean and portable, and the classes are imbued with meaning as to what module they belong to. 

Using class-attribute selectors, we can simplify this further:

[class*=pod] {  }
.pod-form {  }
.pod-sidebar {  }

The *= tells the browser to look for any element with a class attribute containing “pod”, so it matches “pod”, “pod-form”, “pod-sidebar”, etc. This allows only one class per element, resulting in simpler HTML:

<div class=""pod"">
<div class=""pod-form"">
<div class=""pod-sidebar"">

We could further abstract the concept of “form” and “sidebar” adjustments if we knew that each of those alterations would always need the same treatment.

/* Modules */
[class*=pod] {  }
[class*=btn] {  }

/* Alterations */
[class*=-form] {  }
[class*=-sidebar] {  }

In this case, all elements with classes appended “-form” or “-sidebar” would be altered in the same manner, allowing the markup to stay simple:

<form>
  <h2 class=""pod-form"">
  <a class=""btn-form"" href=""#"">

<aside>
  <h2 class=""pod-sidebar"">
  <a class=""btn-sidebar"" href=""#"">

50+ shades of specificity

Classes are just powerful enough to override element selectors and default styling, but still leave room to be trumped by IDs and !important styles. This makes them more suitable for object-oriented patterns and helps avoid messy specificity issues that can not only be a pain for developers to maintain, but can also affect a site’s performance. As Sullivan notes, “In almost every case, classes work well and have fewer unintended consequences than either IDs or element selectors”. Proper use of specificity and cascade is crucial in building straightforward, efficient CSS.

One interesting aspect of attribute selectors is that they can be compounded for increasing levels of specificity. Attribute selectors are assigned a specificity level of ten, the same as class selectors, but both class and attribute selectors can be chained together, giving them more and more specificity with each link. Some examples:

.box {  } 
/* Specificity of 10 */

.box.promo {  } 
/* Specificity of 20 */

[class*=box] {  } 
/* Specificity of 10 */

[class*=box][class*=promo] {  } 
/* Specificity of 20 */

You can chain both types together, too:

.box[class*=promo] {  } 
/* Specificity of 20 */

I was amused to find, though, that you can chain the exact same class and attribute selectors for infinite levels of specificity

.box {  } 
/* Specificity of 10 */

.box.box {  } 
/* Specificity of 20 */

.box.box.box {  } 
/* Specificity of 30 */

[class*=box] {  }
/* Specificity of 10 */

[class*=box][class*=box] {  }
/* Specificity of 20 */

[class*=box][class*=box][class*=box] {  }
/* Specificity of 30 */

.box[class*=box].box[class*=box] {  } 
/* Specificity of 40 */

To override .box styles for promo, we wouldn’t need to add an ID, change the order of .promo and .box in the CSS, or resort to an !important style. Granted, any issue that might need this fine level of specificity tweaking could probably be better solved with clever cascades, but having options never hurts.

Smarter CSS

One of the most powerful aspects of the class-attribute selector is its ability to expand the simple logic found in CSS. When developing Gridset (an online tool for building grids and outputting them as CSS), I realized that with the right class name conventions, class-attribute selectors would allow the CSS to be smart enough to automatically adjust for column offsets without the need for extra classes. This imbued the CSS output with logic that other frameworks lacked, and makes a developer’s job much easier. 

Say you need an element that spans column five (c5) to column six (c6) on your grid, and is preceded by an element spanning column one (c1) to column three (c3). The CSS can anticipate such a scenario:

.c1-c3 + .c5-c6 {
  margin-left: 25%; /* …or the width of column four plus two gutter widths */
}

…but to accommodate all of the margin offsets that could span that same gap, we would need to write a rather protracted list for just a six column grid:

.c1-c3 + .c5-c6,
.c1-c3 + .c5,
.c2-c3 + .c5-c6,
.c2-c3 + .c5,
.c3 + .c5-c6,
.c3 + .c5 {
  margin-left: 25%; 
}

Now imagine how the verbosity compounds when we repeat this type of declaration for every possible margin in a grid. The more columns added to the grid, the longer this selector list would get, too, making the CSS harder for the developer to maintain and slowing the load time. Using class-attribute selectors, though, this can be much simpler:

[class*=c3] + [class*=c5] {
  margin-left: 25%;
}

I’ve detailed how we extract as much logic as possible from as little CSS as needed on the Gridset blog.

More flexible selectors

In a recent project, I was working with Drupal-generated classes to change styles for certain special pages on a site. Without being able to change the code base, I was left trying to find some specific aspect of the generated HTML to target. I noticed that every special page was given a prefixed class, unique to the page, resulting in CSS like this:

.specialpage-about,
.specialpage-contact,
.specialpage-info,
…

…and the list kept growing with each new special page. Such bloat would lead to problems down the line, and add development overhead to editorial decisions, which was a situation we were trying to avoid. I was easily able to fix this, though, with a concise class-attribute selector:

[class*=specialpage-]

The CSS was now flexible enough to accommodate both the editorial needs of the client, and the development restrictions of the CMS.

Selector performance

As Snook tells us in his chapter on Selector Performance, selectors are read by the browser from right to left, matching every element that adheres to each rule (or part of the selector). The more specific we can make the right-most rules – and every other part of your selectors – the more performant your CSS will be. So this selector:

.home-page .promo .main-header

…would be more performant than:

.home-page div header

…because there are likely many more header and div elements on the page, but not so many elements with those specific classes.

Now, the class-attribute selector could be more general than a class selector, but not by much. I ran numerous tests based on the work of Steve Souders (and a few others) to test a class-attribute selector against a normal class selector. Given that Javascript will freeze during style rendering, I created a script that will add, then remove, a stylesheet on a page 5000 times, and measure only the time that elapses during the rendering freeze. The script runs four tests, essentially: one where a class selector and class-attribute Selector match a single element, and one they match multiple elements on the page.

After running the test over 100 times and averaging the results, I have not seen a significant difference in rendering times. (As of this writing, the class-attribute selector has been 0.398% slower on average.) View the results here.

Given the sheer amount of bytes potentially saved by reducing selector lists, though, I am confident class-attribute selectors could shorten load times on larger sites and, at the very least, save precious development time.

Conclusion

With its flexibility and broad remit, class has at times been derided as too lenient, allowing CMSes and lazy developers to fill its values with presentational hacks or verbose gibberish. There have even been calls for an early retirement. Class continues, though, to be one of our most crucial tools.

Front-end developers are rightfully eager to expand production abilities through innovations such as Sass or LESS, but this should not preclude us from honing the tools we already know as well. Every technique demonstrated in this article was achievable over a decade ago and most of the same thinking could be applied to IDs, rels, or any other attribute (though the reasons listed above give class an edge). The recent advent of methods such as object-oriented CSS and SMACSS shows there is still much room left to expand what simple HTML and CSS can accomplish. Progress may not always be found in the innovation of our tools, but through sharpening our understanding of them.",2012,Nathan Ford,nathanford,2012-12-15T00:00:00+00:00,https://24ways.org/2012/a-harder-working-class/,code
276,Your jQuery: Now With 67% Less Suck,"Fun fact: more websites are now using jQuery than Flash.

jQuery is an amazing tool that’s made JavaScript accessible to developers and designers of all levels of experience. However, as Spiderman taught us, “with great power comes great responsibility.” The unfortunate downside to jQuery is that while it makes it easy to write JavaScript, it makes it easy to write really really f*&#ing bad JavaScript. Scripts that slow down page load, unresponsive user interfaces, and spaghetti code knotted so deep that it should come with a bottle of whiskey for the next sucker developer that has to work on it. 

This becomes more important for those of us who have yet to move into the magical fairy wonderland where none of our clients or users view our pages in Internet Explorer. The IE JavaScript engine moves at the speed of an advancing glacier compared to more modern browsers, so optimizing our code for performance takes on an even higher level of urgency.

Thankfully, there are a few very simple things anyone can add into their jQuery workflow that can clear up a lot of basic problems. When undertaking code reviews, three of the areas where I consistently see the biggest problems are: inefficient selectors; poor event delegation; and clunky DOM manipulation. We’ll tackle all three of these and hopefully you’ll walk away with some new jQuery batarangs to toss around in your next project.

Selector optimization

Selector speed: fast or slow?

Saying that the power behind jQuery comes from its ability to select DOM elements and act on them is like saying that Photoshop is a really good tool for selecting pixels on screen and making them change color – it’s a bit of a gross oversimplification, but the fact remains that jQuery gives us a ton of ways to choose which element or elements in a page we want to work with. However, a surprising number of web developers are unaware that all selectors are not created equal; in fact, it’s incredible just how drastic the performance difference can be between two selectors that, at first glance, appear nearly identical. For instance, consider these two ways of selecting all paragraph tags inside a <div> with an ID.

$(""#id p"");

$(""#id"").find(""p"");

Would it surprise you to learn that the second way can be more than twice as fast as the first? Knowing which selectors outperform others (and why) is a pretty key building block in making sure your code runs well and doesn’t frustrate your users waiting for things to happen.

There are many different ways to select elements using jQuery, but the most common ways can be basically broken down into five different methods. In order, roughly, from fastest to slowest, these are:


	$(""#id""); 
This is without a doubt the fastest selector jQuery provides because it maps directly to the native document.getElementbyId() JavaScript method. If possible, the selectors listed below should be prefaced with an ID selector in conjunction with jQuery’s .find() method to limit the scope of the page that has to be searched (as in the $(""#id"").find(""p"") example shown above).
	$(""p"");, $(""input"");, $(""form""); and so on
Selecting elements by tag name is also fast, since it maps directly to the native document.getElementsByTagname() method.
	$("".class""); 
Selecting by class name is a little trickier. While still performing very well in modern browsers, it can cause some pretty significant slowdowns in IE8 and below. Why? IE9 was the first IE version to support the native document.getElementsByClassName() JavaScript method. Older browsers have to resort to using much slower DOM-scraping methods that can really impact performance.
	$(""[attribute=value]"");
There is no native JavaScript method for this selector to use, so the only way that jQuery can perform the search is by crawling the entire DOM looking for matches. Modern browsers that support the querySelectorAll() method will perform better in certain cases (Opera, especially, runs these searches much faster than any other browser) but, generally speaking, this type of selector is Slowey McSlowersons.
	$("":hidden"");
Like attribute selectors, there is no native JavaScript method for this one to use. Pseudo-selectors can be painfully slow since the selector has to be run against every element in your search space. Again, modern browsers with querySelectorAll() will perform slightly better here, but try to avoid these if at all possible. If you must use one, try to limit the search space to a specific portion of the page: $(""#list"").find("":hidden"");


But, hey, proof is in the performance testing, right? It just so happens that said proof is sitting right here. Be sure to notice the class selector numbers beside IE7 and 8 compared to other browsers and then wonder how the people on the IE team at Microsoft manage to sleep at night. Yikes.

Chaining

Almost all jQuery methods return a jQuery object. This means that when a method is run, its results are returned and you can continue executing more methods on them. Rather than writing out the same selector multiple times over, just making a selection once allows multiple actions to be run on it.

Without chaining

$(""#object"").addClass(""active"");
$(""#object"").css(""color"",""#f0f"");
$(""#object"").height(300);

With chaining

$(""#object"").addClass(""active"").css(""color"", ""#f0f"").height(300);

This has the dual effect of making your code shorter and faster. Chained methods will be slightly faster than multiple methods made on a cached selector, and both ways will be much faster than multiple methods made on non-cached selectors. Wait… “cached selector”? What is this new devilry? 

Caching

Another easy way to speed up your code that seems to be a mystery to developers is the idea of caching your selectors. Think of how many times you end up writing the same selector over and over again in any project. Every $("".element"") selector has to search the entire DOM each time, regardless of whether or not that selector had been previously run. Running the selection once and then storing the results in a variable means that the DOM only has to be searched once. Once the results of a selector have been cached, you can do anything with them.

First, run your search (here we’re selecting all of the <li> elements inside <ul id=""blocks"">): 

var blocks = $(""#blocks"").find(""li"");

Now, you can use the blocks variable wherever you want without having to search the DOM every time.

$(""#hideBlocks"").click(function() {
    blocks.fadeOut();
});
$(""#showBlocks"").click(function() {
    blocks.fadeIn();
});

My advice? Any selector that gets run more than once should be cached. This jsperf test shows just how much faster a cached selector runs compared to a non-cached one (and even throws some chaining love in to boot).

Event delegation

Event listeners cost memory. In complex websites and apps it’s not uncommon to have a lot of event listeners floating around, and thankfully jQuery provides some really easy methods for handling event listeners efficiently through delegation.

In a bit of an extreme example, imagine a situation where a 10×10 cell table needs to have an event listener on each cell; let’s say that clicking on a cell adds or removes a class that defines the cell’s background color. A typical way that this might be written (and something I’ve often seen during code reviews) is like so:

$('table').find('td').click(function() {
    $(this).toggleClass('active');
});

jQuery 1.7 has provided us with a new event listener method, .on(). It acts as a utility that wraps all of jQuery’s previous event listeners into one convenient method, and the way you write it determines how it behaves. To rewrite the above .click() example using .on(), we’d simply do the following:

$('table').find('td').on('click',function() {
    $(this).toggleClass('active');
});

Simple enough, right? Sure, but the problem here is that we’re still binding one hundred event listeners to our page, one to each individual table cell. A far better way to do things is to create one event listener on the table itself that listens for events inside it. Since the majority of events bubble up the DOM tree, we can bind a single event listener to one element (in this case, the <table>) and wait for events to bubble up from its children. The way to do this using the .on() method requires only one change from our code above:

$('table').on('click','td',function() {
    $(this).toggleClass('active');
});

All we’ve done is moved the td selector to an argument inside the .on() method. Providing a selector to .on() switches it into delegation mode, and the event is only fired for descendants of the bound element (table) that match the selector (td). With that one simple change, we’ve gone from having to bind one hundred event listeners to just one. You might think that the browser having to do one hundred times less work would be a good thing and you’d be completely right. The difference between the two examples above is staggering.

(Note that if your site is using a version of jQuery earlier than 1.7, you can accomplish the very same thing using the .delegate() method. The syntax of how you write the function differs slightly; if you’ve never used it before, it’s worth checking the API docs for that page to see how it works.)

DOM manipulation

jQuery makes it very easy to manipulate the DOM. It’s trivial to create new nodes, insert them, remove other ones, move things around, and so on. While the code to do this is simple to write, every time the DOM is manipulated, the browser has to repaint and reflow content which can be extremely costly. This is no more evident than in a long loop, whether it be a standard for() loop, while() loop, or jQuery $.each() loop.

In this case, let’s say we’ve just received an array full of image URLs from a database or Ajax call or wherever, and we want to put all of those images in an unordered list. Commonly, you’ll see code like this to pull this off:

var arr = [reallyLongArrayOfImageURLs]; 
    $.each(arr, function(count, item) {
        var newImg = '<li><img src=""'+item+'""></li>';
        $('#imgList').append(newImg);
    });

There are a couple of problems with this. For one (which you should have already noticed if you’ve read the earlier part of this article), we’re making the $(""#imgList"") selection once for each iteration of our loop. The other problem here is that each time the loop iterates, it’s adding a new <li> to the DOM. Each of those insertions is going to be costly, and if our array is quite large then this could lead to a massive slowdown or even the dreaded ‘A script is causing this page to run slowly’ warning.

var arr = [reallyLongArrayOfImageURLs],
    tmp = ''; 
$.each(arr, function(count, item) {
    tmp += '<li><img src=""'+item+'""></li>';
});
$('#imgList').append(tmp);

All we’ve done here is create a tmp variable that each <li> is added to as it’s created. Once our loop has finished iterating, that tmp variable will contain all of our list items in memory, and can be appended to our <ul> all in one go. Browsers work much faster when working with objects in memory rather than on screen, so this is a much faster, more CPU-cycle-friendly method of building a list.

Wrapping up

These are far from being the only ways to make your jQuery code run better, but they are among the simplest ones to implement. Though each individual change may only make a few milliseconds of difference, it doesn’t take long for those milliseconds to add up. Studies have shown that the human eye can discern delays of as few as 100ms, so simply making a few changes sprinkled throughout your code can very easily have a noticeable effect on how well your website or app performs. Do you have other jQuery optimization tips to share? Leave them in the comments and help make us all better.

273,There’s No Formula for Great Designs,"Before he combined them with fluid images and CSS3 media queries to coin responsive design, Ethan Marcotte described fluid grids — one of the most enjoyable parts of responsive design. Enjoyable that is, if you like working with math(s). But fluid grids aren’t perfect and, unless we’re careful when applying them, they can sometimes result in a design that feels disconnected.

Recapping fluid grids

If you haven’t read Ethan’s Fluid Grids, now would be a good time to do that. It centres around a simple formula for converting pixel widths to percentages:

(target ÷ context) × 100 = result

How does that work in practice? Well, take that Fireworks or Photoshop comp you’re working on (I call them static design visuals, or just visuals.) Of course, everything on that visual — column divisions, inline images, navigation elements, everything — is measured in pixels. Now:


	Pick something in the visual and measure its width. That’s our target.
	Take that target measurement and divide it by the width of its parent (context).
	Multiply what you’ve got by 100 (shift two decimal places).
	What you’re left with is a percentage width to drop into your style sheets.


For example, divide this 300px wide sidebar division by its 948px parent and then multiply by 100: your original 300px is neatly converted to 31.646%.

.content-sub {
width : 31.646%; /* 300px ÷ 948px = .31646 */ }

That formula makes it surprisingly simple for even die-hard fixed width aficionados to convert their visuals to percentage-based, fluid layouts.

It’s a handy formula for those who still design using static visuals, and downright essential for those situations where one person in an organization designs in Fireworks or Photoshop and another develops with CSS. Why?

Well, although I think that designing in a browser makes the best sense — particularly when designing for multiple devices — I’ll wager most designers still make visuals in Fireworks or Photoshop and use them for demonstrations and get feedback and sign-off. That’s OK. If you haven’t made the transition to content-out designing in a browser yet, the fluid grids formula helps you carry on pushing pixels a while longer.

You can carry on moving pixel width measurements from your visuals to your style sheets, too, in the same way you always have. You can be precise to the pixel and even apply a grid image as a CSS background to help you keep everything lined up perfectly.

Once you’re done, and the fixed width layout in the browser matches your visual, loop back through your style sheets and convert those pixels to percentages using the fluid grids formula. With very little extra work, you’ll have a fluid implementation of your fixed width layout.

The fluid grids formula is simple and incredibly effective, but not long after I started working responsively I realized that the formula shouldn’t (always) be a one-fix, set-and-forget calculation. I noticed that unless we compensate for problems it sometimes creates, the result can be a disconnected design.

Staying connected

Good design relies on connectedness, a feeling of natural balance between elements and the grid they’re placed on. Give an element greater prominence or position in a visual hierarchy and you can fundamentally alter the balance and sometimes the meaning of a design.

Different from a browser’s page zooming feature — where images, text and overall layout change size by the same ratio — fluid grids flex a layout in response to a window or device width. Columns expand and contract, and within them fluid media (images and videos) can also change size. This can be one of the most impressive demonstrations of responsive design.

But not every element within a fluid grid can change size along with the window or device width. For example, type size and leading won’t change along with a column’s width.

When columns and elements within them change width, all too easily a visual hierarchy can be broken and along with it the relationship between element sizes and the outer window or viewport. This can happen quickly if you make just one set of fluid grid calculations and use those percentages across every screen width, from smartphones through tablets and up to large desktops.

The answer? Make several sets of fluid grids calculations, each one at a significant window or device width breakpoint. Then apply those new percentages, when needed, to help keep elements in proportion and maintain balance and connectedness. Here’s how I work.

Avoiding disconnection

I’ve never been entirely happy with grid frameworks such as the 960 Grid System, so I start almost every project by creating a custom grid to inform my layout decisions. Here’s a plain version of a grid from a recent project that I’ll use as an illustration.

This project’s grid comprises 84px columns and 24px gutters. This creates an odd number of columns at common tablet and desktop widths, and allows for 300px fixed width assets — useful when I need to fit advertising into a desktop layout’s sidebar.

For this project I chose three 320 and Up breakpoints above 320px and, after placing as many columns as would fit those breakpoint widths, I derived three content widths:


		
			Breakpoint 
			Columns 
			Content width 
		
		
			768px 
			 7 
			 732px 
		
		
			992px 
			 9 
			 948px 
		
		
			1,382px 
			 13 
			 1,380px 
		


Here’s my grid again, this time with pixel measurements and breakpoints overlaid.

Now cast your mind back to the fluid grids calculation I made earlier. I divided a 300px element by 948px and arrived at 31.646%. For some elements it’s possible to use that percentage across all screen widths, but others will feel too small in relation to a narrower 768px and too large inside 1,380px.

To help maintain connectedness, I make a set of fluid grids calculations based on each of the content widths I established earlier. Now I can shift an element’s percentage width up or down when I switch to a new breakpoint and content width. For example:


	300px is 40.984% of 732px
	300px is 31.646% of 948px
	300px is 21.739% of 1,380px


I’ll add all those fluid grid percentages to my grid image and save it for quick reference.

Then I can apply those different percentage widths to elements at each breakpoint using CSS3 media queries. For example, that sidebar division again:

/*  732px, 7-column width */

@media only screen and (min-width: 768px) {

    .content-sub {
        width : 40.983%; /* 300px ÷ 732px = .40983 */ }

}

/*  948px, 9-column width */
@media only screen and (min-width: 992px) {

    .content-sub {
        width : 31.645%; /* 300px ÷ 948px = .31645 */ }

}

/*  1380px, 13-column width */
@media only screen and (min-width: 1382px) {

    .content-sub {
        width : 21.739%; /* 300px ÷ 1380px = .21739 */ }

}

The number of changes you make to a layout at different breakpoints will, of course, depend on the specifics of the design you’re working on. Yes, this is additional work, but the result will be a layout that feels better balanced and within which elements remain in harmony with each other while they respond to new screen or device widths.

Putting the design in responsive web design

Until now, many of the conversations around responsive web design have been about aspects of technical implementation, rather than design. I believe we’re only beginning to understand what’s involved in designing responsively. In future, we’ll likely be making design decisions not just about proportions but also about responsive typography. We’ll also need to learn how to adapt our designs to device characteristics such as touch targets and more.

Sometimes we’ll make decisions to improve function, other times because they make a design ‘feel’ right. You’ll know when you’ve made a right decision. You’ll feel it.

After all, there really is no formula for making great designs.",2011,Andy Clarke,andyclarke,2011-12-23T00:00:00+00:00,https://24ways.org/2011/theres-no-formula-for-great-designs/,ux
267,Taming Complexity,"I’m going to step into my UX trousers for this one. I wouldn’t usually wear them in public, but it’s Christmas, so there’s nothing wrong with looking silly.

Anyway, to business. Wherever I roam, I hear the familiar call for simplicity and the denouncement of complexity. I read often that the simpler something is, the more usable it will be. We understand that simple is hard to achieve, but we push for it nonetheless, convinced it will make what we build easier to use. Simple is better, right?

Well, I’ll try to explore that. Much of what follows will not be revelatory to some but, like all good lessons, I think this serves as a welcome reminder that as we live in a complex world it’s OK to sometimes reflect that complexity in the products we build.

Myths and legends

Less is more, we’ve been told, ever since master of poetic verse Robert Browning used the phrase in 1855. Well, I’ve conducted some research, and it appears he knew nothing of web design. Neither did modernist architect Ludwig Mies van der Rohe, a later pedlar of this worthy yet contradictory notion. Broad is narrow. Tall is short. Eggs are chips. See: anyone can come up with this stuff.

To paraphrase Einstein, simple doesn’t have to be simpler. In other words, simple doesn’t dictate that we remove the complexity. Complex doesn’t have to be confusing; it can be beautiful and elegant. On the web, complex can be necessary and powerful. A website that simplifies the lives of its users by offering them everything they need in one site or screen is powerful. For some, the greater the density of information, the more useful the site.

In our decision-making process, principles such as Occam’s razor’s_razor (in a nutshell: simple is better than complex) are useful, but simple is for the user to determine through their initial impression and subsequent engagement. What appears simple to me or you might appear very complex to someone else, based on their own mental model or needs. We can aim to deliver simple, but they’ll be the judge.

As a designer, developer, content alchemist, user experience discombobulator, or whatever you call yourself, you’re often wrestling with a wealth of material, a huge number of features, and numerous objectives. In many cases, much of that stuff is extraneous, and goes in the dustbin. However, it can be just as likely that there’s a truckload of suggested features and content because it all needs to be there. Don’t be afraid of that weight.

In the right hands, less can indeed mean more, but it’s just as likely that less can very often lead to, well… less.

Complexity is powerful

Simple is the ability to offer a powerful experience without overwhelming the audience or inducing information anxiety. Giving them everything they need, without having them ferret off all over a site to get things done, is important.

It’s useful to ask throughout a site’s lifespan, “does the user have everything they need?” It’s so easy to let our designer egos get in the way and chop stuff out, reduce down to only the things we want to see. That benefits us in the short term, but compromises the audience long-term.

The trick is not to be afraid of complexity in itself, but to avoid creating the perception of complexity. Give a user a flight simulator and they’ll crash the plane or jump out. Give them everything they need and more, but make it feel simple, and you’re building a relationship, empowering people.

This can be achieved carefully with what some call gradual engagement, and often the sensible thing might be to unleash complexity in carefully orchestrated phases, initially setting manageable levels of engagement and interaction, gradually increasing the inherent power of the product and fostering an empowered community.

The design aesthetic

Here’s a familiar scenario: the client or project lead gets overexcited and skips most of the important decision-making, instead barrelling straight into a bout of creative direction Tourette’s. Visually, the design needs to be minimal, white, crisp, full of white space, have big buttons, and quite likely be “clean”. Of course, we all like our websites to be clean as that’s more hygienic.

But what do these words even mean, really? Early in a project they’re abstract distractions, unnecessary constraints. This premature narrowing forces us to think much more about throwing stuff out rather than acknowledging that what we’re building is complex, and many of the components perhaps necessary.

Simple is not a formula. It cannot be achieved just by using a white background, by throwing things away, or by breathing a bellowsful of air in between every element and having it all float around in space. Simple is not a design treatment. Simple is hard. Simple requires deep investigation, a thorough understanding of every aspect of a project, in line with the needs and expectations of the audience.

Recognizing this helps us empathize a little more with those most vocal of UX practitioners. They usually appreciate that our successes depend on a thorough understanding of the user’s mental models and expected outcomes. I personally still consider UX people to be web designers like the rest of us (mainly to wind them up), but they’re web designers that design every decision, and by putting the user experience at the heart of their process, they have a greater chance of finding simplicity in complexity. The visual design aesthetic — the façade — is only a part of that.

Divide and conquer

I’m currently working on an app that’s complex in architecture, and complex in ambition. We’ll be releasing in carefully orchestrated private phases, gradually introducing more complexity in line with the unavoidably complex nature of the objective, but my job is to design the whole, the complete system as it will be when it’s out of beta and beyond.

I’ve noticed that I’m not throwing much out; most of it needs to be there. Therefore, my responsibility is to consider interesting and appropriate methods of navigation and bring everything together logically.

I’m using things like smart defaults, graphical timelines and colour keys to make sense of the complexity, techniques that are sympathetic to the content. They act as familiar points of navigation and reference, yet are malleable enough to change subtly to remain relevant to the information they connect. It’s really OK to have a lot of stuff, so long as we make each component work smartly.

It’s a divide and conquer approach. By finding simplicity and logic in each content bucket, I’ve made more sense of the whole, allowing me to create key layouts where most of the simplified buckets are collated and sometimes combined, providing everything the user needs and expects in the appropriate places.

I’m also making sure I don’t reduce the app’s power. I need to reflect the scale of opportunity, and provide access to or knowledge of the more advanced tools and features for everyone: a window into what they can do and how they can help. I know it’s the minority who will be actively building the content, but the power is in providing those opportunities for all.

Much of this will be familiar to the responsible practitioners who build websites for government, local authorities, utility companies, newspapers, magazines, banking, and we-sell-everything-ever-made online shops. Across the web, there are sites and tools that thrive on complexity.

Alas, the majority of such sites have done little to make navigation intuitive, or empower audiences. Where we can make a difference is by striving to make our UIs feel simple, look wonderful, not intimidating — even if they’re mind-meltingly complex behind that façade.

Embrace, empathize and tame

So, there are loads of ways to exploit complexity, and make it seem simple. I’ve hinted at some methods above, and we’ve already looked at gradual engagement as a way to make sense of complexity, so that’s a big thumbs-up for a release cycle that increases audience power.

Prior to each and every release, it’s also useful to rest on the finished thing for a while and use it yourself, even if you’re itching to release. ‘Ready’ often isn’t, and ‘finished’ never is, and the more time you spend browsing around the sites you build, the more you learn what to question, where to add, or subtract. It’s definitely worth building in some contingency time for sitting on your work, so to speak.

One thing I always do is squint at my layouts. By squinting, I get a sort of abstract idea of the overall composition, and general feel for the thing. It makes my face look stupid, but helps me see how various buckets fit together, and how simple or complex the site feels overall.

I mentioned the need to put our design egos to one side and not throw out anything useful, and I think that’s vital. I’m a big believer in economy, reduction, and removing the extraneous, but I’m usually referring to decoration, bells and whistles, and fluff. I wouldn’t ever advocate the complete removal of powerful content from a project roadmap.

Above all, don’t fear complexity. Embrace and tame it. Work hard to empathize with audience needs, and you can create elegant, playful, risky, surprising, emotive, delightful, and ultimately simple things.",2011,Simon Collison,simoncollison,2011-12-21T00:00:00+00:00,https://24ways.org/2011/taming-complexity/,ux
284,Subliminal User Experience,"The term ‘user experience’ is often used vaguely to quantify common elements of the interaction design process: wireframing, sitemapping and so on. UX undoubtedly involves all of these principles to some degree, but there really is a lot more to it than that.

Good UX is characterized by providing the user with constant feedback as they step through your interface. It means thinking about and providing fallbacks and error resolutions in even the rarest of scenarios. It’s about omitting clutter to make way for the necessary, and using the most fundamental of design tools to influence a user’s path. It means making no assumptions, designing right down to the most distinct details and going one step further every single time. In many cases, good UX is completely subliminal.

There are simple tools and subtleties we can build into our products to enhance the overall experience but, in order to do so, we really have to step beyond where we usually draw the line on what to design.

The purpose of this article is not to provide technical how-tos, as the functionality is, in most cases, quite simple and could be implemented in a myriad of ways. Rather, it will present a handful of ideas for enhancing the experience of an interface at a deeper level of design without relying on the container.

We’ll cover three elements that should get you thinking in the right mindset:


	progress activity and post-active states
	pseudo-class preloading
	buttons and their (mis)behaviour


Progress activity and the post-active state

We’ve long established that we can’t control the devices our products are viewed on, which browser they’ll run in or what connection speed will be used to access them. We accept this all as factual, so why is it so often left to the browser to provide feedback to the user when an event is triggered or an error encountered? The browser isn’t part of the interface — it’s merely a container. A simple, visual recognition of your users’ activity may be all it takes to make or break the product.

Let’s begin with a commonly overlooked case: progress activity.

A user moves their cursor over a hyperlink or button, which is clearly defined as one by the visual language of your content. Upon doing so, they trigger the :hover state to confirm this element is indeed interactive. So far, so good. What happens next is where it starts to fall apart: the user hits this link, presumably triggering an :active state, which is then returned to the normal state upon release. And then what?



From this point on, your user is in limbo. The link has fallen back to either its regular or :visited state. You’ve effectively abandoned them and are relying entirely on the browser they’re using to communicate that something is happening. This poses quite a few problems:


	The user may lose focus of what they were doing.
	There is little consistency between progress indication in browsers.
	The user may not even notice that their action has been acknowledged.


How many times have one or more of these events happened to you due to a lack of communication from the interface?

Think about the differences between Safari and Chrome in this area — two browsers that, when compared to each other, are relatively similar in nature, though this basic feature differs in execution.



Like all aspects of designing the user experience, there is no one true way to fix this problem, but we can introduce details that many users will unconsciously appreciate.

Consider the basic loading indicator. It’s nothing new — in fact, some would argue it’s quite a cliché. However, whether using a spinning wheel or a progress bar, a gif or JavaScript, or something more sophisticated, these simple tools create an illusion of movement, progress and activity. Depending on the implementation, progress indication graphics can significantly increase a user’s perception of the speed in which an event is taking place. Combine this with a cursor change and a lock over the element to prevent double-clicking or reloading, and your chances of keeping your user’s valuable attention have significantly increased.

Demo: Progress activity and the post-active state

This same logic applies to all aspects of defaulting in a browser, from micro-elements like this up to something as simple as a 404 page. The difference in a user’s reaction to hitting the default Apache 404 and a hand-crafted, branded page are phenomenal and there are no prizes for guessing which one they’re more likely to exit from.

Pseudo-class preloading

Another detail that it pays well to look after is the use and abuse of the :hover element and, more importantly, the content revealed by it. Chances are you’re using the :hover pseudo-class somewhere in almost every screen you create. If content is being revealed on :hover and that content takes some time to load, there will inevitably be a delay the first time it is initiated. It appears tacky and half-finished when a tooltip or drop-down loads instantly, only to have its background or supporting elements follow through a second or two later. So, let’s preload the elements we know we’ll need.

A very simple application of this would be to load each file into the default state of a visible element and offset them by a large number. This ensures our elements have loaded and are ready if and when they need to be displayed.

element {
    background: url(path/to/image.jpg) -9999em -9999em no-repeat;
    }
element .tooltip {
    display: none;
    }
element:hover .tooltip {
    display: block;
    background: url(path/to/image.jpg) 0 0;
    }

Background images are just one example. Of course, the same logic can apply to any form of revealed content. Using a sprite graphic can also be a clever — albeit tedious — method for achieving the same goal, so if you’re using a sprite, preloading in this way may not be necessary

The differences between preloading and not can only be visualized properly with an actual demonstration.

Demo: Preloading revealed content

Buttons and their (mis)behaviour

Almost all of the time, a button serves just one purpose: to be clicked (or tapped). When a button’s pressed, therefore, if anything other than triggering the desired event occurs, a user naturally becomes frustrated. I often get funny looks when talking about this, but designing the details of a button is something I consider essential.

It goes without saying that a button should always visually recognise :hover and :active states. We can take that one step further and disable some actions that get in the way of pressing the button.

It’s rare that a user would ever want to select and use the text on a button, so let’s cleanly disable it:

element {
    -moz-user-select: -moz-none;
    -webkit-user-select: none;
    user-select: none;
    }

If the button is image-based or contains an image, we could also disable user dragging to make sure the image element stays locked to the button:

element {
    -moz-user-drag: -moz-none;
    -webkit-user-drag: none;
    user-drag: none;
    }

Demo: A more usable button

Disabling global features like this should be done with utmost caution as it’s very easy to cross the line between enhancement and friction. Cases where this is acceptable are very rare, but it’s a good trick to keep in mind nevertheless. Both Apple’s iCloud and Metalab’s Flow applications use these tools appropriately and to great extent.

You could argue that the visual feedback of having the text selected or image dragged when a user mis-hits the button is actually a positive effect, informing the user that their desired action did not work. However, covering for human error should be a designer’s job, not that of our users. We can (almost) ensure it does work for them by accommodating for errors like this in most cases.

Final thoughts

Designing to this level of detail can seem obsessive, but as a designer and user of many interfaces and applications, I believe it can be the difference between a good user experience and a great one.

The samples you’ve just seen are only a fraction of the detail we can design for. Keep in mind that the demonstrations, code and methods above outline just one way to do this. You may not agree with all of these processes or have the time and desire to consider them, but one fact remains: it’s not the technology, or the way it’s done that’s important — it’s the logic and the concept of designing everything.",2011,Chris Sealey,chrissealey,2011-12-03T00:00:00+00:00,https://24ways.org/2011/subliminal-user-experience/,ux
277,Raising the Bar on Mobile,"One of the primary challenges of designing for mobile devices is that screen real estate is often in limited supply. Through the advocacy of Luke W and others, we’ve drawn comfort from the idea that this constraint ends up benefiting users and designers alike, from obvious advantages like portability and reach, to influencing our content strategy decisions through focus and restraint. But that doesn’t mean we shouldn’t take advantage of every last pixel of that screen we can snag!

As anyone who has designed a website for use on a smartphone can attest, there’s an awful lot of space on mobile screens dedicated to browser functions that would be better off toggled out of view. Unfortunately, the visibility of some of these elements is beyond our control, such as the buttons fixed to the bottom of the viewport in iOS’s Safari and the WebOS browser. However, in many devices, the address bar at the top can be manually hidden, and its absence frees up enough pixel room for a large, impactful heading, a critical piece of navigation, or even just a little more white space to air things out.

So, as my humble contribution to this most festive of web publications, today I’ll dig into the approach I used to hide the address bar in a browser-agnostic fashion for sites like BostonGlobe.com, and the jQuery Mobile framework.

Surveying the land

First, let’s assess the chromes of some popular, current mobile browsers. For example purposes, the following screen-captures feature the homepage of the Boston Globe site, without any address-bar-hiding logic in place.

Note: these captures are just mockups – actual experience on these platforms may vary.

 On the left is iOS5’s Safari (running on iPhone), and on the right is Windows Phone 7 (pre-Mango).

 BlackBerry 7 (left), and Android 2.3 (right).

 WebOS (left), Opera Mini (middle), and Opera Mobile (right).

Some browsers, such the default browsers on WebOS and BlackBerry 5, hide the bar automatically without any developer intervention, but many of them don’t. Of these, we can only manually hide the address bar on iOS Safari and Android (according to Opera Web Opener, Mike Taylor, some discussion is underway for support in Opera Mini and Mobile as well, which would be great!). This is unfortunate, but iOS and Android are incredibly popular, so let’s direct our focus there.

Great API, or greatest API?

As it turns out, iOS and Android not only allow you to hide the address bar, they use the same JavaScript method to do so, too (this shouldn’t be surprising, given that they are both WebKit browsers, but nothing expected happens in mobile). However, the method they use is not exactly intuitive. You might set out looking for a JavaScript API dedicated to this purpose, like, say, window.toolbar.hide(), but alas, to hide the address bar you need to use the window.scrollTo method!

window.scrollTo(0, 0);

The scrollTo method is not new, it’s just this particular use of it that is. For the uninitiated, scrollTo is designed to scroll a document to a particular set of coordinates, assuming the document is large enough to scroll to that spot. The method accepts two arguments: a left coordinate; and a top coordinate. It’s both simple and supported well pretty much everywhere. In iOS and Android, these coordinates are calculated from the top of the browser’s viewport, just below the address bar (interestingly, it seems that some platforms like BlackBerry 6 treat the top of the browser chrome as 0 instead, meaning the page content is closer to 20px from the top).

Anyway, by passing the coordinates 0, 0 to the scrollTo method, the browser will jump to the top of the page and pull the address bar out of view! Of course, if a quick call to scrollTo was all we need to do to hide the address bar in iOS and Android, this article would be pretty short, and nothing new. Unfortunately, the first issue we need to deal with is that this method alone will not usually do the trick: it must be called after the page has finished loading.

The browser gives us a load event for just that purpose, so we’ll wrap our scrollTo method in it and continue on our merry way! We’ll use the standard, addEventListener method to bind the the load event, passing arguments for event name load, and a callback function to execute when the event is triggered.

window.addEventListener(""load"",function() {
    window.scrollTo(0, 0);
});

For the sake of preventing errors in those using browsers that don’t support addEventListener, such as Internet Explorer 8 and under, let’s make sure that method exists before we use it:

if( window.addEventListener ){
    window.addEventListener(""load"",function() {
        window.scrollTo(0, 0);
    });
}

Now we’re getting somewhere, but we must also call the method after the load event’s default behavior has been applied. For this, we can use the setTimeout method, delaying its execution to after the load event has run its course.

if( window.addEventListener ){
    window.addEventListener(""load"",function() {
        setTimeout(function(){
            window.scrollTo(0, 0);
        }, 0);
    });
}

Sweet sugar of Christmas! Hit this demo in iOS and watch that address bar drift up and away!

Not so fast…

We’ve got a little problem: the approach above does work in iOS but, in some cases, it works a little too well. In the process of applying this behavior, we’ve broken one of the primary tenets of responsible web development: don’t break the browser’s default behaviour. This usability rule of thumb is often violated by developers with even the best of intentions, from breaking the browser’s back button through unrecorded Ajax page refreshes, to fancy momentum touch scrolling scripts that can wreak havoc in all but the most sophisticated of devices. In this case, we’ve prevented the browser’s native support of deep-linking to sections of a page (a hash identifier in the URL matching a page element’s id attribute, for example, http://example.com#contact) from working properly, because our script always scrolls to the top.

To avoid this collision, we’ll need to detect whether a deep link, or hash, is present in the URL before applying our logic. We can do this by ensuring that the location.hash property is falsey:

if( !window.location.hash && window.addEventListener ){
    window.addEventListener( ""load"",function() {
        setTimeout(function(){
            window.scrollTo(0, 0);
        }, 0);
    });
}

Still works great! And a quick test using a hash-based URL confirms that our script will not execute when a deep anchor is in play. Now iOS is looking sharp, and we’ve added our feature defensively to avoid conflicts.



Now, on to Android…

Wait. You didn’t expect that we could write code for one browser and be finished, right? Of course you didn’t. I mentioned earlier that Android uses the same method for getting rid of the scrollbar, but I left out the fact that the arguments it prefers vary slightly, but significantly, from iOS. Bah!

Differering from the earlier logic from iOS, to remove the address bar on Android’s default browser, you need to pass a Y coordinate of 1 instead of 0. Aside from being just plain odd, this is particularly unfortunate because to any other browser on the planet, 1px is a very real, however small, distance from the top of the page!

window.scrollTo( 0, 1 );

Looks like we’re going to need a fork…

R UA Android?

At this point, some developers might decide to simply not support this feature in Android, and more determined devs might decide that a quick check of the User Agent string would be a reliable way to determine the browser and tweak the scroll value accordingly. Neither of those decisions would be tragic, but in the spirit of cross-browser and future-friendly development, I’ll propose an alternative.

By this point, it should be clear that neither of the implementations above offer a particularly intuitive way to hide an address bar. As such, one might be skeptical that these approaches will stick around very long in their present state in either browser. Perhaps at some point, Android will decide to use 0 like iOS, making our lives a little easier, or maybe some new browser will decide to model their address bar hiding method after one of these implementations. In any case, detecting the User Agent only allows us to apply logic based on the known present, and in the world of mobile, let’s face it, the present is already the past.

Writing a check

In this next step of today’s technique, we’ll apply some logic to quickly determine the behavior model of the browser we’re using, then capitalize on that model – without caring which browser it happens to come from – by applying the appropriate scroll distance.

To do this, we’ll rely on a fortunate side effect of Android’s implementation, which is when you programatically scroll the page to 1 using scrollTo, Android will report that it’s still at 0 because oddly enough, it is! Of course, any other browser in this situation will report a scroll distance of 1. Thus, by scrolling the page to 1, then asking the browser its scroll distance, we can use this artifact of their wacky implementation to our advantage and scroll to the location that makes sense for the browser in play.

Getting the scroll distance

To pull off our test, we’ll need to ask the browser for its current scroll distance. The methods for getting scroll distance are not entirely standardized across popular browsers, so we’ll need to use some cross-browser logic. The following scroll distance function is similar to what you’d find in a library like jQuery. It checks the few common ways of getting scroll distance before eventually falling back to 0 for safety’s sake (that said, I’m unaware of any browsers that won’t return a numeric value from one of the first three properties).

// scrollTop getter
function getScrollTop(){
    return scrollTop  = window.pageYOffset ||
document.compatMode === ""CSS1Compat"" && document.documentElement.scrollTop ||
document.body.scrollTop || 0;
}

In order to execute that code above, the body object (referenced here as document.body) will need to be defined already, or we’ll risk an error. To determine that it’s defined, we can run a quick timer to execute code as soon as that object is defined and ready for use.

var bodycheck = setInterval(function(){
    if( document.body ){
        clearInterval( bodycheck );
        //more logic can go here!!
    }   
}, 15 );

Above, we’ve defined a 15 millisecond interval called bodycheck that checks if document.body is defined and, if so, clears itself of running again. Within that if statement, we can extend our logic further to run other code, such as our check for the scroll distance, defined via the variable scrollTop below:

var scrollTop,
    bodycheck = setInterval(function(){
    if( document.body ){
        clearInterval( bodycheck );
        scrollTop = getScrollTop();
    }   
}, 15 );

With this working, we can immediately scroll to 1, then check the scroll distance when the body is defined. If the distance reports 1, we’re likely in a non-Android browser, so we’ll scroll back to 0 and clean up our mess.

window.scrollTo( 0, 1 );

var scrollTop,
    bodycheck = setInterval(function(){
    if( document.body ){
        clearInterval( bodycheck );
        scrollTop = getScrollTop();
        window.scrollTo( 0, scrollTop === 1 ? 0 : 1 );
    }   
}, 15 );

Cashing in

All of the pieces are written now, so all we need to do is combine them with our previous logic for scrolling when the window is loaded, and we’ll have a cross-browser solution of which John Resig would be proud. Here’s our combined code snippet, with some formatting updates rolled in as well:

(function( win ){
	var doc = win.document;

	// If there’s a hash, or addEventListener is undefined, stop here
	if( !location.hash && win.addEventListener ){
		//scroll to 1
		window.scrollTo( 0, 1 );
		var scrollTop = 1,
			getScrollTop = function(){
				return win.pageYOffset || doc.compatMode = ""CSS1Compat"" && doc.documentElement.scrollTop || doc.body.scrollTop || 0;
			},
			//reset to 0 on bodyready, if needed
			bodycheck = setInterval(function(){
				if( doc.body ){
					clearInterval( bodycheck );
					scrollTop = getScrollTop();
					win.scrollTo( 0, scrollTop = 1 ? 0 : 1 );
				}	
			}, 15 );
		win.addEventListener( “load”, function(){
			setTimeout(function(){
					//reset to hide addr bar at onload
					win.scrollTo( 0, scrollTop === 1 ? 0 : 1 );
			}, 0);
		} );
	}
})( this );
View code example

And with that, we’ve got a bunch more room to play with on both iOS and Android.



Break out the eggnog

…because we’re not done yet! In the spirit of making our script act more defensively, there’s still another use case to consider. It was essential that we used the window’s load event to trigger our scripting, but on pages with a lot of content, its use can come at a cost. Often, a user will begin interacting with a page, scrolling down as they read, before the load event has fired. In those situations, our script will jump the user back to the top of the page, resulting in a jarring experience.

To prevent this problem from occurring, we’ll need to ensure that the page has not been scrolled beyond a certain amount. We can add a simple check using our getScrollTop function again, this time ensuring that its value is not greater than 20 pixels or so, accounting for a small tolerance.

if( getScrollTop() < 20 ){
    //reset to hide addr bar at onload
    window.scrollTo( 0, scrollTop === 1 ? 0 : 1 );
}

And with that, we’re pretty well protected! Here’s a final demo.

Your thoughts?

I hope this article provides you with a browser-agnostic approach to hiding the address bar that you can use in your own projects today. Perhaps alternatively, the complications involved in this approach convinced you that doing this well is more trouble than it’s worth and, depending on the use case, that could be a fair decision. But at the very least, I hope this demonstrates that there’s a lot of work involved in pulling off this small task in only two major platforms, and that there’s a real need for standardization in this area.

Feel free to leave a comment or criticism and I’ll do my best to answer in a timely fashion.

Thanks, everyone!

Some parting notes

I scream, you scream…

At the time of writing, I was not able to test this method on the latest Android 4.0 (Ice Cream Sandwich) build. According to Sencha Touch’s browser scorecard, the browser in 4.0 may have a different way of managing the address bar, so I’ll post in the comments once I get a chance to dig into it further.

Short pages get no love

Today’s technique only works when the page is as tall, or taller than, the device’s available screen height, so that the address bar may be scrolled out of view. On a short page, you might work around this issue by applying a minimum height to the body element ( body { min-height: 460px; } ), but given the variety of screen sizes out there, not to mention changes in orientation, it’s tough to find a value that makes much sense (unless you manipulate it with JavaScript).",2011,Scott Jehl,scottjehl,2011-12-20T00:00:00+00:00,https://24ways.org/2011/raising-the-bar-on-mobile/,design
281,Nine Things I've Learned,"I’ve been a professional graphic designer for fourteen years and for just under four of those a professional web designer. Like most designers I’ve learned a lot in my time, both from a design point of view and in business as freelance designer. A few of the things I’ve learned stick out in my mind, so I thought I’d share them with you. They’re pretty random and in no particular order.

1. Becoming the designer you want to be

When I started out as a young graphic designer, I wanted to design posters and record sleeves, pretty much like every other young graphic designer. The problem is that the reality of the world means that when you get your first job you’re designing the back of a paracetamol packet or something equally weird. I recently saw a tweet that went something like this: “You’ll never become the designer you always dreamt of being by doing the work you never wanted to do”. This is so true; to become the designer you want to be, you need to be designing the things you’re passionate about designing. This probably this means working in the evenings and weekends for little or no money, but it’s time well spent. Doing this will build up your portfolio with the work that really shows what you can do! Soon, someone will ask you to design something based on having seen this work. From this point, you’re carving your own path in the direction of becoming the designer you always wanted to be.

2. Compete on your own terms

As well as all being friends, we are also competitors. In order to win new work we need a selling point, preferably a unique selling point. Web design is a combination of design disciplines – user experience design, user interface Design, visual design, development, and so on. Some companies will sell themselves as UX specialists, which is fine, but everyone who designs a website from scratch does some sort of UX, so it’s not really a unique selling point. Of course, some people do it better than others.

One area of web design that clients have a strong opinion on, and will judge you by, is visual design. It’s an area in which it’s definitely possible to have a unique selling point. Designing the visual aesthetic for a website is a combination of logical decision making and a certain amount of personal style. If you can create a unique visual style to your work, it can become a selling point that’s unique to you.

3. How much to charge and staying motivated

When you’re a freelance designer one of the hardest things to do is put a price on your work and skills. Finding the right amount to charge is a fine balance between supplying value to your customer and also charging enough to stay motivated to do a great job. It’s always tempting to offer a low price to win work, but it’s often not the best approach: not just for yourself but for the client as well.

A client once asked me if I could reduce my fee by £1,000 and still be motivated enough to do a good job. In this case the answer was yes, but it was the question that resonated with me. I realized I could use this as a gauge to help me price projects. Before I send out a quote I now always ask myself the question “Is the amount I’ve quoted enough to make me feel motivated to do my best on this project?” I never send out a quote unless the answer is yes. In my mind there’s no point in doing any project half-heartedly, as every project is an opportunity to build your reputation and expand your portfolio to show potential clients what you can do. Offering a client a good price but not being prepared to put everything you have into it, isn’t value for money.  

4. Supplying the right design

When I started out as a graphic designer it seemed to be the done thing to supply clients with a ton of options for their logo or brochure designs. In a talk given by Dan Rubin, he mentioned that this was a legacy of agencies competing with each other in a bid to create the illusion of offering more value for money. Over the years, I’ve realized that offering more than one solution makes no sense. The reason a client comes to you as a designer is because you’re the person than can get it right. If I  were to supply three options, I’d be knowingly offering my client at least two options that I didn’t think worked.

To this day I still get asked how many homepage design options I’ll supply for the quoted amount. The answer is one. Of course, I’m more than happy to iterate upon the design to fine-tune it and, on the odd occasion, I do revisit a design concept if I just didn’t nail the design first time around. Your time is much better spent refining the right design option than rushing out three substandard designs in the same amount of time.

5. Colour is key

There are many contributing factors that go into making a good visual design, but one of the simplest ways to do this is through the use of colour. The colour palette used in a design can have such a profound effect on a visual design that it almost feels like you’re cheating. It’s easy to add more and more subtle shades of colour to add a sense of sophistication and complexity to a design, but it dilutes the overall visual impact. When I design, I almost have a rule that only allows me to use a very limited colour palette. I don’t always stick to it, but it’s always in mind and something I’m constantly reviewing through my design process.

6. Creative thinking is central to good or boundary-pushing web design

When we think of creativity in web design we often link this to the visual design, as there is an obvious opportunity to be creative in this area if the brief allows it. Something that I’ve learnt in my time as a web designer is that there’s a massive need for creative thinking in the more technical aspects of web design. The tools we use for building websites are there to be manipulated and used in creative ways to design exciting and engaging user experiences. Great developers are constantly using their creativity to push the boundaries of what can be done with CSS, jQuery and JavaScript. 

Being creative and creative thinking are things we should embrace as an industry and they are qualities that can be found in anyone, whether they be a visual designer or Rails developer.

7. Creative block: don’t be afraid to get things wrong

Creative block can be a killer when designing. It’s often applied to visual design, which is more subjective. I suffer from creative block on a regular basis. It’s hugely frustrating and can screw up your schedule. Having thought about what creative block actually is, I’ve come to the conclusion that it’s actually more of a lack of direction than a lack of ideas. You have ideas and solutions in mind but don’t feel committed to any of them. You’re scared that whatever direction you take, it’ll turn out to be wrong. I’ve found that the best remedy for this is to work through this barrier. It’s a bit like designing with a blindfold on – you don’t really know where you’re going. If you stick to your guns and keep pressing forward I find that, nine times out of ten, this process leads to a solution. As the page begins to fill, the direction you’re looking for slowly begins to take shape.

8. You get better at designing by designing

I often get emails asking me what books someone can read to help them become a better designer. There are a lot of good books on subjects like HTML5, CSS, responsive web design and the like, that will really help improve anyone’s web design skills. But, when it comes to visual design, the best way to get better is to design as much as possible. You can’t follow instructions for these things because design isn’t following instructions. A large part of web design is definitely applying a set of widely held conventions, but there’s another part to it that is invention and the only way to get better at this is to do it as much as possible.

9. Self-belief is overrated

Throughout our lives we’re told to have self-belief. Self-belief and confidence in what we do, whatever that may be. The problem is that some people find it easier than others to believe in themselves. I’ve spent years trying to convince myself to believe in what I do but have always found it difficult to have complete confidence in my design skills. Self-doubt always creeps in.

I’ve realized that it’s ok to doubt myself and I think it might even be a good thing!  I’ve realized that it’s my self-doubt that propels me forward and makes me work harder to achieve the best results. The reason I’m sharing this is because I know I’m not the only designer that feels this way. You can spend a lot of time fighting self-doubt only to discover that it’s your body’s natural mechanism to help you do the best job possible.",2011,Mike Kus,mikekus,2011-12-11T00:00:00+00:00,https://24ways.org/2011/nine-things-ive-learned/,business
278,Going Both Ways,"It’s that time of the year again: Santa is getting ready to travel the world. Up until now, girls and boys from all over have sent in letters asking for what they want. I hope that Santa and his elves have—unlike me—learned more than just English.

On the Internet, those girls and boys want to participate in sharing their stories and videos of opening presents and of being with friends and family. Ah, yes, the wonders of user generated content. But more than that, people also want to be able to use sites in the language they know.

While you and I might expect the text to read from left to right, not all languages do. Some go from right to left, such as Arabic and Hebrew. (Some also go from top to bottom, but for now, let’s just worry about those first two directions!)

If we were building a site for girls and boys to send their letters to Santa, we need to consider having the interface in the language and direction that they prefer. On the elves’ side, they may be viewing the site in one direction but reading the user generated content in the other direction. We need to build a site that supports bidirectional (or bidi) text.

Let’s take a look at some things to be aware of when it comes to building bidi interfaces.

Setting the direction of the interface

Right off the bat, we need to tell the browser what direction the text should be going in. To do this, we add the dir attribute to an HTML element and set it to either LTR (for left to right) or RTL (for right to left).

<body dir=""rtl"">

You can add the dir attribute to any element and it will set or change the direction for the content within that element. 

<body dir=""ltr"">
   Here is English Content.
   <div dir=""rtl"">الموضوع</div>
</body>

You can also set the direction via CSS.

.rtl {
    direction: rtl;
    }

It’s generally recommended that you don’t use CSS to set the direction of the text. Text direction is an important part of the content that should be retained even in environments where the CSS may not be available or fails to load.

How things change with the direction attribute

Just adding the dir attribute tells the browser to render the content within it differently. 



The text aligns to the right of the page and, interestingly, punctuation appears at the left of the sentence. (We’ll get to that in a little bit.) 

Scrollbars in most browsers will appear on the left instead of the right. Webkit is the notable exception here which always shows the scrollbar on the right, no matter what the text direction is. Avoid having a design that has an expectation that the scrollbar will be in a specific place (and a specific size).

Changing the order of text mid-way

As we saw in that previous example, the punctuation appeared at the beginning of the sentence instead of the end, even though the text was English. At Yahoo!, we have an interesting dilemma where the company name has punctuation in it. Therefore, when the name appears in the middle of (for example) Arabic text, the exclamation mark appears at the beginning of the word instead of the end.



There are two ways in which this problem can be solved:

1. Use HTML around the left-to-right content, or

To solve the problem of the Yahoo! name in the midst of Arabic text, we can wrap a span around it and change the direction on that element.



2. Use a text direction mark in the content.

Unicode has two marks, U+200E and U+200F, that tell the browser that the text is in a particular direction. Placing this right after the punctuation will correct the placement.

Using the HTML entity:
Yahoo!‎

Tables

Thankfully, the cells of a data table also get reordered from right to left. Equally as nice, if you’re using display:table, the content will still get reordered.



CSS

So far, we’ve seen that the dir attribute does a pretty decent job of getting content flowing in the direction that we need it. Unfortunately, there are huge swaths of design that is handled by CSS that the handy dir attribute has zero effect over.

Many properties, like float or absolute positioning with left and right values, are unaffected and must be handled manually. Elements that were floated left must now by floated right. Left margins and paddings must now move to the right and the right margins and paddings must now move to the left.

Since the browser won’t handle this for us, we have a couple approaches that we can use:

CSS Only

We can take advantage of the attribute selector to target CSS to apply in one direction or another.

[dir=ltr] .module {
	float: left;
	margin: 0 0 0 20px;
}

[dir=rtl] .module {
	float: right;
	margin: 0 20px 0 0;
}

As you can see from this example, both of the properties have been modified for the flipped interface. If your interface is rather complicated, you will have to create a lot of duplicate rules to have the site looking good in both directions while serving up a single stylesheet.

CSSJanus

Google has a tool called CSSJanus. It’s a Python script that runs over the LTR versions of your CSS files and generates RTL versions. For the RTL version of the site, just serve up those CSS files instead of the LTR versions.

The script looks for keywords and value combinations and automatically swaps them so you don’t have to. 

At Yahoo!, CSSJanus was a huge help in speeding up our development of a bidi interface. We’ve also made a number of improvements to the script to better handle border radius, background positioning, and gradients. We will be pushing those changes back into the CSSJanus project. 



Background Images

Background images, especially for things like CSS sprites, also raise an interesting dilemma. Background images are positioned relative to the left of the element. In a flipped interface, however, we need to position it relative to the right. An icon that would be to the left of some text will now need to appear on the right.



If the x position of the background is percentage-based, then it’s fairly easy to swap the values. 0 becomes 100%, 10% becomes 90% and so on. If the x position is pixel-based, then we’re in a bit of a pickle. There’s no way to say that the image should be a certain number of pixels from the right.

Therefore, you’ll need to ensure that any background image that needs to be swapped should be percentage-based. (99.9% of the the time, the background position will need to be 0 so that it can be changed to 100% for RTL.)

If you’re taking an existing implementation, background positioning will likely be the biggest hurdle you’ll have to overcome in swapping your interface around. If you make sure your x position is always percentage-based from the beginning, you’ll have a much smoother process ahead of you!

Flipping Images

This is a more subtle point and one where you’ll really want an expert with the region to weigh in on. In RTL interfaces, users may expect certain icons to also be flipped. Pencil icons that skew to the right in LTR interfaces might need to be swapped to skew to the left, instead. Chat bubbles that come from the left will need to come from the right.

The easiest way to handle this is to create new images. Name the LTR versions with -ltr in the name and name the RTL versions with -rtl in the name. CSSJanus will automatically rename all file references from -ltr to -rtl.

The Future

Thankfully, those within the W3C recognize that CSS should be more agnostic. As a result, they’ve begun introducing new properties that allow the browser to manage the swapping from left to right for us.

The CSS3 specification for backgrounds allows for the background-position to be relative to other corners other than the top left by specifying keywords before each position.

This will position the background 5px from the bottom right of the element.

background-position: right 5px bottom 5px;

Opera 11.60 is currently the only browser that supports this syntax.

For margin and padding, we have margin-start and margin-end. In LTR interfaces, margin-start would be the same as margin-left and in RTL interfaces, margin-start would be the same as margin-right. 

Firefox and Webkit support these but with vendor prefixes right now:

-webkit-margin-start: 20px;
-moz-margin-start: 20px;

In the CSS3 Images working draft specification, there’s an image() property that allows us to specify image fallbacks and whether those fallbacks are for LTR or RTL interfaces.

background: image('sprite.png' ltr, 'sprite-rtl.png' rtl);

Unfortunately, no browser supports this yet but it’s nice to be able to dream of how much easier this will be in the future!

Ho Ho Ho

Hopefully, after all of this, you’re full of cheer knowing that you’re well on your way to creating interfaces that can go both ways!",2011,Jonathan Snook,jonathansnook,2011-12-19T00:00:00+00:00,https://24ways.org/2011/going-both-ways/,ux
268,Getting the Most Out of Google Analytics,"Something a bit different for today’s 24 ways article. For starters, I’m not a designer or a developer. I’m an evil man who sells things to people on the internet. Second, this article will likely be a little more nebulous than you’re used to, since it covers quite a number of points in a relatively short space. 

This isn’t going to be the complete Google Analytics Conversion University IQ course compressed into a single article, obviously. What it will be, however, is a primer on setting up and using Google Analytics in real life, and a great deal of what I’ve learned using Google Analytics nearly every working day for the past six (crikey!) years.

Also, to be clear, I’ll be referencing new Google Analytics here; old Google Analytics is for loooosers (and those who want reliable e-commerce conversion data per site search term, natch).

You may have been running your Analytics account for several years now, dipping in and out, checking traffic levels, seeing what’s popular… and that’s about it. Google Analytics provides so much more than that, but the number of reports available can often intimidate users, and documentation and case studies on their use are minimal at best. 

Let’s start! Setting up your Analytics profile

Before we plough on, I just want to run through a quick checklist that some basic settings have been enabled for your profile. If you haven’t clicked it, click the big cog on the top-right of Google Analytics and we’ll have a poke about.


	If you have an e-commerce site, e-commerce tracking has been enabled

	If your site has a search function, site search tracking has been enabled.
	Query string parameters that you do not want tracked as separate pages have been excluded (for example, any parameters needed for your platform to function, otherwise you’ll get multiple entries for the same page appearing in your reports)
	Filters have been enabled on your main profile to exclude your office IP address and any IPs of people who frequently access the site for work purposes. In decent numbers they tend to throw data off a tad.

	You may also find the need to set up multiple profiles prefiltered for specific audience segments. For example, at Lovehoney we have seventeen separate profiles that allow me quick access to certain countries, devices and traffic sources without having to segment first. You’ll also find load time for any complex reports much improved. Use the same filter screen as above to set up a series of profiles that only include, say, mobile visits, or UK visitors, so you can quickly analyse important segments.


Matt, what’s a segment?

A segment is a subsection of your visitor base, which you define and then call on in reports to see specific data for that subsection. For example, in this report I’ve defined two segments, the first for IE6 users and the second for IE7.



Segments are easily created by clicking the Advanced Segments tabs at the top of any report and clicking +New Custom Segment.



What does your site do?

Understanding the goals of your site is an oft-covered topic, but it’s necessary not just to form a better understand of your business and prioritize your time. Understanding what you wish visitors to do on your site translates well into a goal-driven analytics package like Google Analytics.  

Every site exists essentially to sell something, either financially through e-commerce, or to sell an idea or impart information, get people to download a CV or enquire about service, or to sell space on that website to advertisers. If the site did not provide a positive benefit to its owners, it would not have a reason for being. 

Once you have understood the reason why you have a site, you can map that reason on to one of the three goal types Google Analytics provides. 

E-commerce 

This conversion type registers transactions as part of a sales process which requires a monetary value, what products have been bought, an SKU (stock keeping unit), affiliation (if you’re then attributing the sale to a third party or franchise) and so on.

The benefit of e-commerce tracking is not only assigning non-arbitrary monetary value to behaviour of visitors on your site, as well as being able to see ancillary costs such as shipping, but seeing product-level information, like which products are preferred from various channels, popular categories, and so on.



However, I find the e-commerce tracking options also useful for non-e-commerce sites. For example, if you’re offering downloads or subscriptions and having an email address or user’s details is worth something to you, you can set up e-commerce tracking to understand how much value your site is bringing. For example, an email address might be worth 20p to you, but if it also includes a name it’s worth 50p. A contact telephone number is worth £2, and so on.

Page goals

Page goals, unsurprisingly, track a visit to a page (often with a sequence of pages leading up to that page). This is what’s referred to as a goal funnel, and is generally used to track how visitors behave in a multistep checkout. 



Interestingly, the page doesn’t have to actually exist. For example, if you have a single page checkout, you can register virtual page views using trackPageview() when a visitor clicks into a particular section of the checkout or other form. If your site is geared towards getting someone to a particular page, but where there isn’t a transaction (for example, a subscription page) this is for you.

There are also behavioural goals, such as time on site and number of pages viewed, which are geared towards sites that make money from advertising.

But, going back to the page goals, these can be abstracted using regular expressions, meaning that you can define a funnel based on page type rather than having to set individual folders.



In this example, I’ve created regexes for the main page types on my site, so I can create a wide funnel that captures visitors from where they enter through to checkout.

Events

Event tracking registers a predefined event, such as playing a video, or some interaction that can trigger JavaScript, such as a Tweet This button. Events can then be triggered using the trackEvent() call. If you want someone to complete watching a video, you would code your player to fire trackEvent() upon completion. 

While I don’t use events as goals, I use events elsewhere to see how well a video play aids to conversion. This not only helps me justify the additional spend on creating video content, but also quickly highlights which videos are underperforming as sales tools.



What a visitor can tell you


Now you have some proper goals set up, we can start to see how changes in content (on-site and external) affect those goals. 

Ultimately, when a visitor comes to your site, they bring information with them:


	where they came from (a search engine – including: keyword searched for; a referral; direct; affiliate; or ad campaign)
	demographics (country; whether they’re new or returning, within thirty days)
	technical information (browser; screen size; device; bandwidth)
	site-specific information (landing page; next click; previous values assigned to them as custom variables*)


 * A note about custom variables. There’s no hope in hell that I can cover custom variables in this article. Go research them. Custom variables are the single best way to hack Google Analytics and bend it to your will. Custom variables allow you to record anything you want about a visitor, which that visitor will then carry around with them between visits. It’s also great for plugging other services into Google Analytics (as shown by the marvelous way Visual Website Optimizer allows you to track and segment tests within the GA interface). Just make sure not to breach the terms of service, eh?

CSI your website

Police procedural TV shows are all the same: the investigators are called to a crime and come across a clue; there’s then an autopsy; new evidence leads them to a new location; they find a new clue; they put two and two together; they solve the mystery.

This is your life now. Exciting!

So, now you’re gathering a wealth of information about what sort of people visit your site, what they do when they’re there, and what eventually gets them to drive value to you. It’s now your job to investigate all these little clues to see which types of people drive the most value, and what you can change to improve it.

Maybe not that exciting.

However, Google Analytics comes pre-armed with extensive reports for you to delve into. As an e-commerce guy (as opposed to a page goal guy) my day pretty much follows the pattern below.


	Look at e-commerce conversion rate by traffic source compared to the same day in the previous week and previous month. As ours is an e-commerce site, we have weekly and monthly trends. A big spike on Sundays and Mondays, and payday towards the end of the month is always good; on the third week of a month there tends to be a lull. Spend time letting your Google Analytics data brew, understand your own trends and patterns, and you’ll start to get a feel for when something isn’t quite right.
	
		Traffic Sources → Sources → All Traffic
	
	Look at the conversion rate by landing page for any traffic source that feels significantly different to what’s expected. Check bounce rates, drill down to likely landing pages and check search keyword or referral site to see if it’s a particular subset of visitor. You can do this by clicking Secondary Dimension and choosing Keyword or Source. If it’s direct, choose Visitor Type to break down by new or returning visitor.
	
		Content → Site Content → Landing Pages
	
	I then tend to flip into Content Drilldown to see what the next clicks were from those landing pages, and whether they changed significantly to the date I’m comparing with. If they have, that’s usually an indicator of changed content (or its relevancy). Remember, if a bunch of people have found their way to your page via a method you’re not expecting (such as a mention on a Spanish radio station – this actually happened to me once), while the content hasn’t changed, the relevancy of it to the audience may have.
	
		Content → Site Content → Content Drilldown
	
	Once I have an idea of what content was consumed, and whether it was relevant to the user, I then look at the visitor specifics, such as browser or demographic data, to see again whether the change was limited to a specific subset. Site speed, for example, is normally a good factor towards bounce rate, so compare that with previous data as well.


Now, to be investigating at this level you still need a serious amount of data, in order to tell what’s a significant change or not. If you’re struggling with a small number of visitors, you might find reporting on a weekly or fortnightly basis more appropriate. 

However, once you’ve looked into the basics of why changes happen to the value of your site, you’ll soon find yourself limited by the reports offered in Standard Reporting. So, it’s time to build your own. Hooray!

Custom reporting

Google Analytics provides the tools to build reports specific to the types of investigations you frequently perform. 



Welcome to my world.

Custom reports are quite simple to build: first, you determine the metric you want the report to cover (number of visitors, bounce rate, conversion rate, and so on), then choose a set of dimensions that you’d like to segment the report by (say, the source of the traffic, and whether they were new or returning users). You can filter the report, including or excluding particular dimension values, and you can assign the report to any of the profiles you created earlier. 

In the example below, I’ve created a report that shows me visits and conversion rate for any Google traffic that landed directly only on a product page. I can then drill down on each product page to see the complete phrases use to search. I can use this information in two ways:


	I can see which products aren’t converting, which shows me where I need to work harder on merchandising.
	I can give this information to my content team, showing them the actual phrases visitors used to reach our product content, helping them write better targeted product descriptions.




The possibilities here are nearly endless, but here are a few examples of reports I find useful:


	Non-brand inbound search
By creating a report that shows inbound search traffic which doesn’t include your brand, you can see more clearly the behaviour of visitors most likely to be unfamiliar with your site and brand values, without having to rely on the clumsy new or returning demographic date.
	Traffic/conversion/sales by hour
This is pure stats porn, but actually more useful than real-time data. By seeing this data broken down at an hourly level, you can not only compare the current day to previous days, but also see the best performing times for email broadcasts and tweets.
	Visits, load time, conversion and sales by page and browser
Page speed can often kill conversion rates, but it’s difficult to prove the value of focusing on speed in monetary terms. Having this report to hand helps me drive Operation Greenbelt, our effort to get into the sub-1.5 second band in Google Webmaster Tools.


Useful things you can’t do in custom reporting

If you have a search function on your website, then Conversion Rate and Products Bought by Site Search Term is an incredibly useful report that allows you to measure the effectiveness of your site’s search engine at returning products and content related to the search term used. By including the products actually bought by visitors who searched for each term, you can use this information to better searchandise these results, escalating high propensity and high value products to the top of the results.

However, it’s not possible to get this information out of new Google Analytics. 

Try it, select the following in the report builder:


	Metrics: total unique searches; e-commerce or goal conversion rate
	Dimensions: search term; product


You’ll see that the data returned is a little nonsensical, though a 2,000% conversion rate would be nice. However, you can get more accurate information using advanced segments. By creating individual segments to define users who have searched for a particular term, you can run the sales performance and product performance reports as normal. It’s laborious, but it teaches a good lesson: data that seems inaccessible can normally be found another way!

Reporting infrastructure

Now that you have a series of reports that you can refer to on a daily or weekly basis, it’s time to put together a regular reporting infrastructure. 

Even if you’re not reporting to someone, having a set of key performance indicators that you can use to see how your performance is improving over time allows you to set yourself business goals on a monthly and annual basis.

For my own reporting, I take some high-level metrics (such as visitors, conversion rate and average order value), and segment them by traffic source and, separately, landing page. These statistics I record weekly and report:


	current week compared with previous week
	same week previous year (if available)
	4 week average
	13 week average
	52 week average (if available)


This takes into account weekly, monthly, seasonal and annual trends, and gives you a much clearer view of your performance.

Getting data in other ways

If you’re using Google Analytics frequently, with any large site you’ll come to a couple of conclusions:


	Doing any kind of practical comparative analysis is unwieldy.
	Boy, Google Analytics is slow!


As you work with bigger datasets and put together more complex queries, you’ll see the loading graphic more than you’ll see actual data. So when you reach that level, there are ways to completely bypass the Google Analytics interface altogether, and get data into your own spreadsheet application for manipulation.

Data Feed Query Explorer

If you just want to pull down some quick statistics but still use complex filters and exotic metric and dimension combinations, the Data Feed Query Explorer is the quickest way of doing so. Authenticate with your Google Analytics account, select a profile, and you can start selecting metrics and dimensions to be generated in a handy, selectable tabulated format.

Google Analytics API

If you’re feeling clever, you can bypass having to copy and paste data by pulling in directly into Excel, Google Docs or your own application using the Google Analytics API. There are several scripts and plugins available to do this. I use Automate Analytics Google Docs code (there’s also a paid version that simplifies setup and creates some handy reports for you).

New shiny things

Well, now that that’s over, I can show you some cool stuff. Well, at least it’s cool to me. Google Analytics is being constantly improved and new functionality is introduced nearly every month. Here are a couple of my favourites.

Multichannel attribution

Not every visitor converts on your site on the first visit. They may not even do so on the second visit, or third. If they convert on the fourth visit, but each time they visit they do so via a different channel (for example, Search PPC, Search Organic, Direct, Email), which channel do you attribute the conversion to? The last channel, or the first? Dilemma!  

Google now has a Multichannel Attribution report, available in the Conversion category, which shows how each channel assists in converting, the overlap between channels, and where in the process that channel was important. 



For example, you may have analysed your blog traffic from Twitter and become disheartened that not many people were subscribing after visiting from Twitter links, but instead your high-value subscribers were coming from natural search. On the face of it, you’d spend less time tweeting, but a multichannel report may tell you that visitors first arrived via a Twitter link and didn’t subscribe, but then came back later after searching for your blog name on Google, after which they did. Don’t pack Twitter in yet!

Visitor and goal flow

Visitor and goal flow are amazing reports that help you visualize the flow of traffic through your site and, ultimately, into your checkout funnel or similar goal path. Flow reports are perfect for understanding drop-off points in your process, as well as what the big draws are on each page. 



Previously, if you wanted to visualize this data you had to set up several abstracted microgoals and chain them together in custom reports. Frankly, it was a pain in the arse and burned through your precious and limited goal allocation.

Visitor flow bypasses all that and produces the report in an interactive flow diagram. While it doesn’t show you the holy grail of conversion likelihood by each path, you can segment visitor flow so that you can see very specifically how different segments of your visitor base behave.

Go play with it now!",2011,Matt Curry,mattcurry,2011-12-18T00:00:00+00:00,https://24ways.org/2011/getting-the-most-out-of-google-analytics/,business
282,Front-end Style Guides,"We all know that feeling: some time after we launch a site, new designers and developers come in and make adjustments. They add styles that don’t fit with the content, use typefaces that make us cringe, or chuck in bloated code. But if we didn’t leave behind any documentation, we can’t really blame them for messing up our hard work.

To counter this problem, graphic designers are often commissioned to produce style guides as part of a rebranding project. A style guide provides details such as how much white space should surround a logo, which typefaces and colours a brand uses, along with when and where it is appropriate to use them.

Design guidelines

Some design guidelines focus on visual branding and identity. The UK National Health Service (NHS) refer to theirs as “brand guidelines”. They help any designer create something such as a trustworthy leaflet for an NHS doctor’s surgery. Similarly, Transport for London’s “design standards” ensure the correct logos and typefaces are used in communications, and that they comply with the Disability Discrimination Act.

Some guidelines go further, encompassing a whole experience, from the visual branding to the messaging, and the icon sets used. The BBC calls its guidelines a “Global Experience Language” or GEL. It’s essential for maintaining coherence across multiple sites under the same BBC brand.


The BBC’s Global Experience Language.

Design guidelines may be brief and loose to promote creativity, like Mozilla’s “brand toolkit”, or be precise and run to many pages to encourage greater conformity, such as Apple’s “Human Interface Guidelines”.

Whatever name or form they’re given, documenting reusable styles is invaluable when maintaining a brand identity over time, particularly when more than one person (who may not be a designer) is producing material.

Code standards documents

We can make a similar argument for code. For example, in open source projects, where hundreds of developers are submitting code, it makes sense to set some standards. Drupal and Wordpress have written standards that make editing code less confusing for users, and more maintainable for contributors.

Each community has nuances: Drupal requests that developers indent with two spaces, while Wordpress stipulates a tab. Whatever the rules, good code standards documents also explain why they make their recommendations.

The front-end developer’s style guide

Design style guides and code standards documents have been a successful way of ensuring brand and code consistency, but in between the code and the design examples, web-based style guides are emerging. These are maintained by front-end developers, and are more dynamic than visual design guidelines, documenting every component and its code on the site in one place.

Here are a few examples I’ve seen in the wild:

Natalie Downe’s pattern portfolio

Natalie created the pattern portfolio system while working at Clearleft. The phrase describes a single HTML page containing all the site’s components and styles that can act as a deliverable.


Pattern portfolio by Natalie Downe for St Paul’s School, kept up to date when new components are added. The entire page is about four times the length shown.

Each different item within a pattern portfolio is a building block or module. The components are decoupled from the layout, and linearized so they can slot into anywhere on a page.


	The pattern portfolio expresses every component and layout structure in the smallest number of documents. It sets out how the markup and CSS should be, and is used to illustrate the project’s shared vocabulary.

	Natalie Downe


By developing a system, rather than individual pages, the result is flexible when the client wants to add more pages later on.

Paul Lloyd’s style guide

Paul Lloyd has written an extremely comprehensive style guide for his site. Not only does it feature every plausible element, but it also explains in detail when it’s appropriate to use each one.


Paul’s style guide is also great educational material for people learning to write code.

Oli Studholme’s style guide

Even though Oli’s style guide is specific to his site, he’s written it as though it’s for someone else. It’s exhaustive and gives justifications for all his decisions. In some places, he links to browser bug tickets and makes recommendations for cross-browser compatibility.


Oli has released his style guide under a Creative Commons Attribution Share-alike license, and encourages others to create their own versions.

Jeremy Keith’s pattern primer

Front-end style guides may have comments written in the code, annotations that appear on the page, or they may list components alongside their code, like Jeremy’s pattern primer.


You can watch or fork Jeremy’s pattern primer on Github.



Linearizing components like this resembles a kind of mobile first approach to development, which Jeremy talks about on the 5by5 podcast: The Web Ahead 3.

The benefits of maintaining a front-end style guide

If you still need convincing that producing documentation like this for every project is worth the effort, here are a few nice side-effects to working this way:

Easier to test

A unified style guide makes it easier to spot where your design breaks. It’s simple to check how components adapt to different screen widths, test for browser bugs and develop print style sheets when everything is on the same page. When I worked with Natalie, she’d resize the browser window and bump the text size up and down during development to see if anything would break.

Better workflow

The approach also forces you to think how something works in relation to the whole site, rather than just a specific page, making it easier to add more pages later on. Starting development by creating a style guide makes a lot more sense than developing on a page-by-page basis.

Shared vocabulary

Natalie’s pattern portfolio in particular creates a shared vocabulary of names for components (teaser, global navigation, carousel…), so a team can refer to different regions of the site and have a shared understanding of its meaning.

Useful reference

A combined style guide also helps designers and writers to see the elements that will be incorporated in the site and, therefore, which need to be designed or populated. A boilerplate list of components for every project can act as a reminder of things that may get missed in the design, such as button states or error messages. 

Creating your front-end style guide

As you’ve seen, there are plenty of variations on the web style guide. Which method is best depends on your project and workflow. Let’s say you want to show your content team how blockquotes and asides look, when it’s appropriate to use them, and how to create them within the CMS. In this case, a combination of Jeremy’s pattern primer and Paul’s descriptive style guide – with the styled component alongside a code snippet and a description of when to use it – may be ideal. 

Start work on your style guide as soon as you can, preferably during the design stage:


	Simply presenting flat image comps is by no means enough - it’s only the start… As layouts become more adaptable, flexible and context-specific, so individual components will become the focus of our design. It is therefore essential to get the foundational aspects of our designs right, and style guides allow us to do that.

	Paul Lloyd on Style guides for the Web 



	Print out the designs and label the unique elements and components you’ll need to add to your style guide. Make a note of the purpose of each component. While you’re doing this, identify the main colours used for things like links, headings and buttons.
I draw over the print-outs on to tracing paper so I can make more annotations. Here, I’ve started annotating the widths from the designer’s mockup so I can translate these into percentages.
	Start developing your style guide with base styles that target core elements: headings, links, tables, blockquotes, ordered lists, unordered lists and forms. For these elements, you could maintain a standard document to reuse for every project.
	Next, add the components that override the base styles, like search boxes, breadcrumbs, feedback messages and blog comments. Include interaction styles, such as hover, focus and visited state on links, and hover, focus and active states on buttons.
	Now start adding layout and begin slotting the components into place. You may want to present each layout as a separate document, or you could have them all on the same page stacked beneath one another.


Document code practices

Code can look messy when people use different conventions, so note down a standard approach alongside your style guide. For example, Paul Stanton has documented how he writes CSS.

The gift wrapping

Presenting this documentation to your client may be a little overwhelming so, to be really helpful, create a simple page that links together all your files and explains what each of them do.


This is an example of a contents page that Clearleft produce for their clients. They’ve added date stamps, subversion revision numbers and written notes for each file.

Encourage participation

There’s always a risk that the person you’re writing the style guide for will ignore it completely, so make your documentation as user-friendly as possible. Justify why you do things a certain way to make it more approachable and encourage similar behaviour.

As always, good communication helps. Working with the designer to put together this document will improve the site. It’s often not practical for designers to provide a style for everything, so drafting a web style guide and asking for feedback gives designers a chance to make sure any default styles fit in.

If you work in a team with other developers, documenting your code and development decisions will not only be useful as a deliverable, but will also force you to think about why you do things a certain way.

Future-friendly

The roles of designer and developer are increasingly blurred, yet all too often we work in isolation. Working side-by-side with designers on web style guides can vastly improve the quality of our work, and the collaborative approach can spark discussions like “how would this work on a smaller screen?”

Sometimes we can be so focused on getting the site ready and live, that we lose sight of what happens after it’s launched, and how it’s going to be maintained. A simple web style guide can make all the difference.

If you make your own style guide, I’d love to add it to my stash of examples so please share a link to it in the comments.",2011,Anna Debenham,annadebenham,2011-12-07T00:00:00+00:00,https://24ways.org/2011/front-end-style-guides/,process
270,From Side Project to Not So Side Project,"In the last article I wrote for 24 ways, back in 2009, I enthused about the benefits of having a pet project, suggesting that we should all have at least one so that we could collaborate with our friends, escape our day jobs, fulfil our own needs, help others out, raise our profiles, make money, and — most importantly — have fun. I don’t think I need to offer any further persuasions: it seems that designers and developers are launching their own pet projects left, right and centre. This makes me very happy.

However, there still seems to be something of a disconnect between having a side project and turning it into something that is moderately successful; in particular, the challenge of making enough money to sustain the project and perhaps even elevating it from the sidelines so that it becomes something not so on the side at all.

Before we even begin this, let’s spend a moment talking about money, also known as…

Evil, nasty, filthy money

Over the last couple of years, I’ve started referring to myself as an accidental businessman. I say accidental because my view of the typical businessman is someone who is driven by money, and I usually can’t stand such people. Those who are motivated by profit, obsessed with growth, and take an active interest in the world’s financial systems don’t tend to be folks with whom I share a beer, unless it’s to pour it over them. Especially if they’re wearing pinstriped suits.

That said, we all want to make money, don’t we? And most of us want to make a relatively decent amount, too. I don’t think there’s any harm in admitting that, is there? Hello, I’m Elliot and I’m a capitalist.

The key is making money from doing what we love. For most people I know in our community, we’ve already achieved that — I’m hard-pressed to think of anyone who isn’t extremely passionate about working in our industry and I think it’s one of the most positive, unifying benefits we enjoy as a group of like-minded people — but side projects usually arise from another kind of passion: a passion for something other than what we do as our day jobs. Perhaps it’s because your clients are driving you mental and you need a break; perhaps it’s because you want to create something that is truly your own; perhaps it’s because you’re sick of seeing your online work disappear so fast and you want to try your hand at print in order to make a more permanent mark.

The three factors I listed there led me to create 8 Faces, a printed magazine about typography that started as a side project and is now a very significant part of my yearly output and income.

Like many things that prove fruitful, 8 Faces’ success was something of an accident, too. For a start, the magazine was never meant to be profitable; its only purpose at all was to scratch my own itch. Then, after the first issue took off and I realized how much time I needed to spend in order to make the next one decent, it became clear that I would have to cover more than just the production costs: I’d have to take time out from client work as well. Doing this meant I’d have to earn some money. Probably not enough to equate to the exact amount of time lost when I could be doing client work (not that you could ever describe time as being lost when you work on something you love), but enough to survive; for me to feel that I was getting paid while doing all of the work that 8 Faces entailed. The answer was to raise money through partnerships with some cool companies who were happy to be associated with my little project.

A sustainable business model

Business model! I can’t believe I just wrote those words! But a business model is really just a loose plan for how not to screw up. And all that stuff I wrote in the paragraph above about partnering with companies so I could get some money in while I put the magazine together? Well, that’s my business model. 

If you’re making any product that has some sort of production cost, whether that’s physical print run expenses or up-front dev work to get an app built, covering those costs before you even release your product means that you’ll be in profit from the first copy you sell. This is no small point: production expenses are pretty much the only cost you’ll ever need to recoup, so having them covered before you launch anything is pretty much the best possible position in which you could place yourself. Happy days, as Jamie Oliver would say.

Obtaining these initial funds through partnerships has another benefit. Sure, it’s a form of advertising but, done right, your partners can potentially provide you with great content, too. In the case of 8 Faces, the ads look as nice as the rest of the magazine, and a couple of our partners also provide proper articles: genuinely meaningful, relevant, reader-pleasing articles at that. You’d be amazed at how many companies are willing to become partners and, as the old adage goes, if you don’t ask, you don’t get.

With profit comes responsibility

Don’t forget about the responsibility you have to your audience if you engage in a relationship with a partner or any type of advertiser: although I may have freely admitted my capitalist leanings, I’m still essentially a hairy hippy, and I feel that any partnership should be good for me as a publisher, good for the partner and — most importantly — good for the reader. Really, the key word here is relevance, and that’s where 99.9% of advertising fails abysmally. 

(99.9% is not a scientific figure, but you know what I’m on about.)

The main grey area when a side project becomes profitable is how you share that profit, partly because — in my opinion, at least — the transition from non-profitable side project to relatively successful source of income can be a little blurred. Asking for help for nothing when there’s no money to be had is pretty normal, but sometimes it’s easy to get used to that free help even once you start making money. I believe the best approach is to ask for help with the promise that it will always be rewarded as soon as there’s money available. (Oh, god: this sounds like one of those nightmarish client proposals. It’s not, honest.) If you’re making something cool, people won’t mind helping out while you find your feet.

Events often think that they’re exempt from sharing profit. Perhaps that’s because many event organizers think they’re doing the speakers a favour rather than the other way around (that’s a whole separate article), but it’s shocking to see how many people seem to think they can profit from content-makers — speakers, for example — and yet not pay for that content. It was for this reason that Keir and I paid all of our speakers for our Insites: The Tour side project, which we ran back in July. We probably could’ve got away without paying them, especially as the gig was so informal, but it was the right thing to do.

In conclusion: money as a by-product

Let’s conclude by returning to the slightly problematic nature of money, because it’s the pivot on which your side project’s success can swing, regardless of whether you measure success by monetary gain. I would argue that success has nothing to do with profit — it’s about you being able to spend the time you want on the project. Unfortunately, that is almost always linked to money: money to pay yourself while you work on your dream idea; money to pay for more servers when your web app hits the big time; money to pay for efforts to get the word out there. The key, then, is to judge success on your own terms, and seek to generate as much money as you see fit, whether it’s purely to cover your running costs, or enough to buy a small country. There’s nothing wrong with profit, as long as you’re ethical about it. (Pro tip: if you’ve earned enough to buy a small country, you’ve probably been unethical along the way.)

The point at which individuals and companies fail — in the moral sense, for sure, but often in the competitive sense, too — is when money is the primary motivation. It should never be the primary motivation. If you’re not passionate enough about something to do it as an unprofitable side project, you shouldn’t be doing it all. 

Earning money should be a by-product of doing what you love. And who doesn’t want to spend their life doing what they love?",2011,Elliot Jay Stocks,elliotjaystocks,2011-12-22T00:00:00+00:00,https://24ways.org/2011/from-side-project-to-not-so-side-project/,business
287,Extracting the Content,"As we throw away our canvas in approaches and yearn for a content-out process, there remains a pain point: the Content. It is spoken of in the hushed tones usually reserved for Lord Voldemort. The-thing-that-someone-else-is-responsible-for-that-must-not-be-named.

Designers and developers have been burned before by not knowing what the Content is, how long it is, what style it is and when the hell it’s actually going to be delivered, in internet eons past. Warily, they ask clients for it. But clients don’t know what to make, or what is good, because no one taught them this in business school. Designers struggle to describe what they need and when, so the conversation gets put off until it’s almost too late, and then everyone is relieved that they can take the cop-out of putting up a blog and maybe some product descriptions from the brochure.

The Content in content out.

I’m guessing, as a smart, sophisticated, and, may I say, nicely-scented reader of the honourable and venerable tradition of 24 ways, that you sense something better is out there. Bunches of boxes to fill in just don’t cut it any more in a responsive web design world. The first question is, how are you going to design something to ensure users have the easiest access to the best Content, if you haven’t defined at the beginning what that Content is? Of course, it’s more than possible that your clients have done lots of user research before approaching you to start this project, and have a plethora of finely tuned Content for you to design with.

Have you finished laughing yet? Alright then. Let’s just assume that, for whatever reason of gross oversight, this hasn’t happened. What next?

Bringing up Content for the first time with a client is like discussing contraception when you’re in a new relationship. It might be awkward and either party would probably rather be doing something else, but it needs to be broached before any action happens (that, and it’s disastrous to assume the other party has the matter in hand). If we can’t talk about it, how can we expect people to be doing it right and not making stupid mistakes? That being the case, how do we talk about Content? Let’s start by finding a way to talk about it without blushing and scuffing our shoes. And there’s a reason I’ve been treating Content as a Proper Noun. 

The first step, and I mean really-first-step-way-back-at-the-beginning-of-the-project-while-you-are-still-scoping-out-what-the-hell-you-might-do-for-each-other-and-it’s-still-all-a-bit-awkward-like-a-first-date, is for you to explain to the client how important it is that you, together, work out what is important to your users as part of the user experience design, so that your users get the best user experience. The trouble is that, in most cases, this would lead to blank stares, possibly followed by a light cough and a query about using Comic Sans because it seems friendly.

Let’s start by ensuring your clients understand the task ahead. You see, all the time we talk about the Content we do our clients a big disservice. Content is poorly defined. It looms over a project completion point like an unscalable (in the sense of a dozen stacked Kilimanjaros), seething, massive, singular entity. The Content.

Defining the problem. 

We should really be thinking of the Content as ‘contents’; as many parts that come together to form a mighty experience, like hit 90s kids’ TV show Mighty Morphin Power Rangers*.

*For those of you who might have missed the Power Rangers, they were five teenagers with attitude, each given crazy mad individual skillz and a coloured lycra suit from an alien overlord. In return, they had to fight a new monster of the week using their abilities and weaponry in sync (even if the audio was not) and then, finally, in thrilling combination as a Humongous Mechanoid Machine of Awesome. They literally joined their individual selves, accessories and vehicles into a big robot. It was a toy manufacturer’s wet dream.

So, why do I say Content is like the Power Rangers? Because Content is not just a humongous mecha. It is a combination of well-crafted pieces of contents that come together to form a well-crafted humongous mecha. Of Content.

The Red Power Ranger was always the leader. You can imagine your text contents, found on about pages, product descriptions, blog articles, and so on, as being your Red Power Ranger.

Maybe your pictures are your Yellow Power Ranger; video is Blue (not used as much as the others, but really impressive when given a good storyline); maybe Pink is your infographics (it’s wrong to find it sexier than the other equally important Rangers, but you kind of do anyway). And so on. 

These bits of content – Red Text Ranger, Yellow Picture Ranger and others – often join together on a page, like they are teaming up to fight the bad guy in an action scene, and when they all come together (your standard workaday huge mecha) in a launched site, that’s when Content becomes an entity.

While you might have a vision for the whole site, Content rarely works that way. Of course, you keep your eye on the bigger prize, the completion of your mega robot, but to get there you need to assemble your working parts, the cogs and springs of contents that will mesh together to finally create your Humongous Mecha of Content. You create parts and join them to form a whole. (It’s rarely seamless; often we need to adjust as we go, but we can create our Mecha’s blueprint by making sure we have all the requisite parts.)

The point here is the order these parts were created. No alien overlord plans a Humongous Mechanoid and then thinks, “Gee, how can I split this into smaller fighting units powered by teenagers in snazzy shiny suits?” No toy manufacturer goes into production of a mega robot, made up of model mecha vehicles with detachable arsenal, without thinking how they will easily fit back together to form the ‘Buy all five now to create the mega robot’ set. No good contents are created as a singular entity and chunked up to be slotted in to place any which way, into the body of a site.

Think contents, not the Content. Think of contents as smaller units, or as a plural. The Content is what you have at the end. The contents are what you are creating and they are easy to break down. You are no longer scaling the unscalable. You can draw the map and plot the path, page by page, section by section.

The page table is your friend

To do this, I use a page table. A page table is a simple table template you can create in the word processor of your choice, that you use to tell you everything about the contents of a page – everything except the contents itself. 

Here’s a page table I created for an employee’s guide to redundancy in the alpha.gov.uk website:

This particular page table template owes a lot to Brain Traffic’s version found in Kristina Halvorson’s book Content Strategy for the Web. With smaller clients than, say, the government, I might use something a bit more casual. With clients who like timescales and deadlines, I might turn it into a covering sheet, with signatures and agreements from two departments who have to work together to get the piece done on time.

I use page tables, and the process of working through them, to reassure clients that I understand the task they face and that I can help them break it down section by section, page stack to page, down to product descriptions and interaction copy. About 80% of my clients break into relieved smiles. Most clients want to work with you to produce something good, they just don’t understand how, and they want you to show them the mountain path on the map. With page tables, clients can understand that with baby steps they can break down their content requirements and commission content they need in time for the designers to work with it (as opposed to around it).  If I was Santa, these clients would be on my nice list for sure.

My own special brand of Voldemort-content-evilness comes in how I wield my page tables for the other 20%. Page tables are not always thrilling, I’ll admit. Sometimes they get ignored in favour of other things, yet they are crucial to the continual growth and maintenance of a truly content-led site. For these naughty list clients who, even when given the gift of the page table, continually say “Ooh, yes. Content. Right”, I have a special gift. I have a stack of recycled paper under my desk and a cheap black and white laser printer. And I print a blank page table for every conceivable page I can find on the planned redesign. If I’m feeling extra nice, I hole punch them and put them in a fat binder. 

There is nothing like saying, “This is all the contents you need to have in hand for launch”, and the satisfying thud the binder makes as it hits the table top, to galvanize even the naughtiest clients to start working with you to create the content you need to really create in a content-out way.",2011,Relly Annett-Baker,rellyannettbaker,2011-12-15T00:00:00+00:00,https://24ways.org/2011/extracting-the-content/,content
288,Displaying Icons with Fonts and Data- Attributes,"Traditionally, bitmap formats such as PNG have been the standard way of delivering iconography on websites. They’re quick and easy, and it also ensures they’re as pixel crisp as possible. Bitmaps have two drawbacks, however: multiple HTTP requests, affecting the page’s loading performance; and a lack of scalability, noticeable when the page is zoomed or viewed on a screen with a high pixel density, such as the iPhone 4 and 4S.

The requests problem is normally solved by using CSS sprites, combining the icon set into one (physically) large image file and showing the relevant portion via background-position. While this works well, it can get a bit fiddly to specify all the positions. In particular, scalability is still an issue. A vector-based format such as SVG sounds ideal to solve this, but browser support is still patchy.



The rise and adoption of web fonts have given us another alternative. By their very nature, they’re not only scalable, but resolution-independent too. No need to specify higher resolution graphics for high resolution screens! 

That’s not all though:


	Browser support: Unlike a lot of new shiny techniques, they have been supported by Internet Explorer since version 4, and, of course, by all modern browsers. We do need several different formats, however!
	Design on the fly: The font contains the basic graphic, which can then be coloured easily with CSS – changing colours for themes or :hover and :focus styles is done with one line of CSS, rather than requiring a new graphic. You can also use CSS3 properties such as text-shadow to add further effects. Using -webkit-background-clip: text;, it’s possible to use gradient and inset shadow effects, although this creates a bitmap mask which spoils the scalability.
	Small file size: specially designed icon fonts, such as Drew Wilson’s Pictos font, can be as little as 12Kb for the .woff font. This is because they contain fewer characters than a fully fledged font. You can see Pictos being used in the wild on sites like Garrett Murray’s Maniacal Rage.


As with all formats though, it’s not without its disadvantages: 


	Icons can only be rendered in monochrome or with a gradient fill in browsers that are capable of rendering CSS3 gradients. Specific parts of the icon can’t be a different colour.
	It’s only appropriate when there is an accompanying text to provide meaning. This can be alleviated by wrapping the text label in a tag (I like to use <b> rather than <span>, due to the fact that it’s smaller and isn’ t being used elsewhere) and then hiding it from view with text-indent:-999em.
	Creating an icon font can be a complex and time-consuming process. While font editors can carry out hinting automatically, the best results are achieved manually.
	Unless you’re adept at creating your own fonts, you’re restricted to what is available in the font. However, fonts like Pictos will cover the most common needs, and icons are most effective when they’re using familiar conventions.


The main complaint about using fonts for icons is that it can mean adding a meaningless character to our markup. The good news is that we can overcome this by using one of two methods – CSS generated content or the data-icon attribute – in combination with the :before and :after pseudo-selectors, to keep our markup minimal and meaningful. 

Our simple markup looks like this:

<a href=""/basket"" class=""icon basket"">View Basket</a>

Note the multiple class attributes. Next, we’ll import the Pictos font using the @font-face web fonts property in CSS:

@font-face {
    font-family: 'Pictos';
    src: url('pictos-web.eot');
    src: local('☺'), 
    url('pictos-web.woff') format('woff'), 
    url('pictos-web.ttf') format('truetype'),
    url('pictos-web.svg#webfontIyfZbseF') format('svg');
}

This rather complicated looking set of rules is (at the time of writing) the most bulletproof way of ensuring as many browsers as possible load the font we want.  We’ll now use the content property applied to the :before pseudo-class selector to generate our icon. Once again, we’ll use those multiple class attribute values to set common icon styles, then specific styles for .basket. This helps us avoid repeating styles:

.icon {
    font-family: 'Pictos';
    font-size: 22px:
}

.basket:before {
    content: ""$"";
}

What does the :before pseudo-class do? It generates the dollar character in a browser, even when it’s not present in the markup. Using the generated content approach means our markup stays simple, but we’ll need a new line of CSS, defining what letter to apply to each class attribute for every icon we add.

data-icon is a new alternative approach that uses the HTML5 data- attribute in combination with CSS attribute selectors. This new attribute lets us add our own metadata to elements, as long as its prefixed by data- and doesn’t contain any uppercase letters. In this case, we want to use it to provide the letter value for the icon. Look closely at this markup and you’ll see the data-icon attribute.

<a href=""/basket"" class=""icon"" data-icon=""$"">View Basket</a>



We could add others, in fact as many as we like.

<a href=""/"" class=""icon"" data-icon=""k"">Favourites</a>
<a href=""/"" class=""icon"" data-icon=""t"">History</a>
<a href=""/"" class=""icon"" data-icon=""@"">Location</a>



Then, we need just one CSS attribute selector to style all our icons in one go:

.icon:before {
    content: attr(data-icon);
    /* Insert your fancy colours here */
    }

By placing our custom attribute data-icon in the selector in this way, we can enable CSS to read the value of that attribute and display it before the element (in this case, the anchor tag). It saves writing a lot of CSS rules. I can imagine that some may not like the extra attribute, but it does keep it out of the actual content – generated or not.





This could be used for all manner of tasks, including a media player and large simple illustrations. See the demo for live examples. Go ahead and zoom the page, and the icons will be crisp, with the exception of the examples that use -webkit-background-clip: text as mentioned earlier.

Finally, it’s worth pointing out that with both generated content and the data-icon method, the letter will be announced to people using screen readers. For example, with the shopping basket icon above, the reader will say “dollar sign view basket”. As accessibility issues go, it’s not exactly the worst, but could be confusing. You would need to decide whether this method is appropriate for the audience. Despite the disadvantages, icon fonts have huge potential.",2011,Jon Hicks,jonhicks,2011-12-12T00:00:00+00:00,https://24ways.org/2011/displaying-icons-with-fonts-and-data-attributes/,code
265,Designing for Perfection,"Hello, 24 ways readers. I hope you’re having a nice run up to Christmas. This holiday season I thought I’d share a few things with you that have been particularly meaningful in my work over the last year or so. They may not make you wet your santa pants with new-idea-excitement, but in the context of 24 ways I think they may serve as a nice lesson and a useful seasonal reminder going into the New Year. Enjoy!

Story

Despite being a largely scruffy individual for most of my life, I had some interesting experiences regarding kitchen tidiness during my third year at university. 

As a kid, my room had always been pretty tidy, and as a teenager I used to enjoy reordering my CDs regularly (by artist, label, colour of spine – you get the picture); but by the time I was twenty I’d left most of these traits behind me, mainly due to a fear that I was turning into my mother. The one remaining anally retentive part of me that remained however, lived in the kitchen. For some reason, I couldn’t let all the pots and crockery be strewn across the surfaces after cooking. I didn’t care if they were washed up or not, I just needed them tidied. The surfaces needed to be continually free of grated cheese, breadcrumbs and ketchup spills. Also, the sink always needed to be clear. Always. Even a lone teabag, discarded casually into the sink hours previously, would give me what I used to refer to as “kitchen rage”.

Whilst this behaviour didn’t cause any direct conflicts, it did often create weirdness. We would be happily enjoying a few pre-night out beverages (Jack Daniels and Red Bull – nice) when I’d notice the state of the kitchen following our round of customized 49p Tesco pizzas. Kitchen rage would ensue, and I’d have to blitz the kitchen, which usually resulted in me having to catch everyone up at the bar afterwards.

One evening as we were just about to go out, I was stood there, in front of the shithole that was our kitchen with the intention of cleaning it all up, when a realization popped into my head. In hindsight, it was a pretty obvious one, but it went along the lines of “What the fuck are you doing? Sort your life out”. I sodded the washing up, rolled out with my friends, and had a badass evening of partying.

After this point, whenever I got the urge to clean the kitchen, I repeated that same realization in my head. My tidy kitchen obsession strived for a level of perfection that my housemates just didn’t share, so it was ultimately pointless. It didn’t make me feel that good, either; it was like having a cigarette after months of restraint – initially joyous but soon slightly shameful.

Lesson

Now, around seven years later, I’m a designer on the web and my life is chaotic. It features no planning for significant events, no day-to-day routine or structure, no thought about anything remotely long-term, and I like to think I do precisely what I want. It seems my days at striving for something ordered and tidy, in most parts of my life, are long gone.

For much of my time as a designer, though, it’s been a different story. I relished industry-standard terms such as ‘pixel perfection’ and ‘polished PSDs’, taking them into my stride as I strove to design everything that was put on my plate perfectly. Even down to grids and guidelines, all design elements would be painstakingly aligned to a five-pixel grid. There were no seven-pixel margins or gutters to be found in my design work, that’s for sure. I put too much pride and, inadvertently, too much ego into my work. Things took too long to create, and because of the amount of effort put into the work, significant changes, based on client feedback for example, were more difficult to stomach.

Over the last eighteen months I’ve made a conscious effort to change the way I approach designing for the web. Working on applications has probably helped with this; they seem to have a more organic development than rigid content-based websites. Mostly though, a realization similar to my kitchen rage one came about when I had to make significant changes to a painstakingly crafted Photoshop document I had created. The changes shouldn’t have been difficult or time-consuming to implement, but they were turning out to be. One day, frustrated with how long it was taking, the refrain “What the fuck are you doing? Sort your life out” again entered my head. I blazed the rest of the work, not rushing or doing scruffy work, but just not adhering to the insane levels of perfection I had previously set for myself. When the changes were presented, everything went down swimmingly. The client in this case (and I’d argue most cases) cared more about the ideas than the perfect way in which they had been implemented. I had taken myself and my ego out of the creative side of the work, and it had been easier to succeed.

Argument

I know many other designers who work on the web share such aspirations to perfection. I think it’s a common part of the designer DNA, but I’m not sure it really has a place when designing for the web.

First, there’s the environment. The landscape in which we work is continually shifting and evolving. The inherent imperfection of the medium itself makes attempts to create perfect work for it redundant. Whether you consider it a positive or negative point, the products we make are never complete. They’re always scaling and changing. 

Like many aspects of web design, this striving for perfection in our design work is a way of thinking borrowed from other design industries where it’s more suited. A physical product cannot be as easily altered or developed after it has been manufactured, so the need to achieve perfection when designing is more apt.

Designers who can relate to anything I’ve talked about can easily let go of that anal retentiveness if given the right reasons to do so. Striving for perfection isn’t a bad thing, but I simply don’t think it can be achieved in such a fast-moving, unique industry. I think design for the web works better when it begins with quick and simple, followed by iteration and polish over time. 

To let go of ego and to publish something that you’re not completely happy with is perhaps the most difficult part of the job for designers like us, but it’s followed by a satisfaction of knowing your product is alive and breathing, whereas others (possibly even competitors) may still be sitting in Photoshop, agonizing over whether a margin should be twenty or forty pixels.

I keep telling myself to stop sitting on those two hundred ideas that are all half-finished. Publish them, clean them up and iterate over time. I’ve been telling myself this for months and, hopefully, writing this article will give me the kick in the arse I need. Hopefully, it will also give someone else the same kick.",2011,Greg Wood,gregwood,2011-12-17T00:00:00+00:00,https://24ways.org/2011/designing-for-perfection/,process
279,Design the Invisible to Tell Better Stories on the Web,"For design to be meaningful we need to tell stories. We need to design the invisible, the cues, the messages and the extra detail hidden beneath the aesthetics. It’s all about the story.



From verbal exchanges around the campfire to books, the web and everything in between, storytelling allows us to share, organize and process information more efficiently. It helps us understand our surroundings and make emotional connections to people, places and experiences.

Web design lends itself perfectly to the conventions of storytelling, a universal process. However, the stories vary because they’re defined by culture, society, politics and religion. All of which need considering if you are to design stories that are relevant to your target audience.

The benefits of approaching design with storytelling in mind from the very start of the project is that we are creating considered design that allows users to quickly gather meaning from the website. They do this by reading between the lines and drawing on the wealth of knowledge they have acquired about the associations between colours, typyefaces and signs.

With so much recognition and analysis happening subconsciously you have to consider how design communicates on this level. This invisible layer has a significant impact on what you say, how you say it and who you say it to.

How can we design something that’s invisible?

By researching and making conscious decisions about exactly what you are communicating, you can make the invisible visible. As is often quoted, good design is like air, you only notice it when it’s bad. So by designing the invisible the aim is to design stories that the audience receive subliminally, so that they go somewhat unnoticed, like good air.

Storytelling strands

To share these stories through design, you can break it down into several strands. Each strand tells a story on its own, but when combined they may start to tell a different story altogether. These strands are colour, typefaces, branding, tone of voice and symbols. All are literal and visible but the invisible element is the meaning behind them – meaning that you can extract and share. In this article I want to focus on colour, typefaces and tone of voice and on how combining story strands can change the meaning.

Colour

Let’s start with colour. Red represents emotions such as love but can also signify war. Green is commonly used for all things environmental and purple is a colour that connotes wealth and royalty. These associations between colour and emotion or value have been learned over time and are continually reinforced through media and culture. 



With this knowledge come expectations from your users. For example, they will expect Valentine’s Day sites to be red and kids’ sites to be bright and colourful. This is true in the same way audiences have expectations of certain genres of film or music. These conventions help savvy audiences decode texts and read between the lines or, rather, to draw meaning from the invisible. It’s practically an innate skill. This is why you need to design the invisible: because users will quickly deduce meaning from your site and fill in the story’s gaps, it’s important to give them as much of that story to begin with. A story relevant to their culture.



Of all the ways you can tell stories through web design, colour is the most fascinating and important. Not only does it evoke emotions in users but its meaning varies significantly between cultures. In the west, for example, white is a colour associated with weddings, and black is the colour of mourning. This is signified by the traditions of brides wearing white and those in mourning wearing black. In other cultures the meanings are reversed, as black is a colour that represents good luck and white is a colour that signifies mourning. If you assume the same values are true in all cultures then you risk offending the very people you are targeting.

When colours combine, the story being told can change. If you design using red, white and blue then it’s going to be difficult to shake off patriotic connotations because this colour combination is so ingrained as being American or British or French thanks largely to their flags. This extends to politics too. Each party has its own representative colour. In the UK, the Conservatives are blue and Labour is red so it would be inappropriate storytelling to design a Labour-related website in blue as there would be a conflict between the content and the design, a conflict that would result in a poor user experience.

Conflicts become more of an issue when you start to combine story strands. I once saw a No VAT advert use the symbol on the left:



There’s a complete conflict in storytelling here between the sign and its colour. The prohibition sign was used over the word VAT to mean no VAT; that makes sense. But this is a symbol that is used to communicate to people that something is being prohibited or prevented, it mustn’t continue. So to use green contradicts the message of the sign itself; green is used as a colour to say yes, go, proceed, enter. The same would be true if we had a tick in red and a cross in green. Bad design here means the story is flawed and the user experience is compromised.

Typefaces

Typefaces also tell stories. They are so much more than the words that are written with them because they connote different values. Here are a few:



Serif fonts are more formal and are associated with tradition, sophistication and high-end values. Sans serif fonts, on the other hand, are synonymous with modernity, informality and friendliness. These perceptions are again reinforced through more traditional media such as newspaper mastheads, where the serious news-focused broadsheets have serif titles, and the showbiz and gossip-led tabloids have sans serif titles. This translates to the web as well. With these associations already familiar to users, they may see copy and focus on the words, but if the way that copy is displayed jars with the context then we are back to having conflicting stories like the No VAT sign earlier.

Let’s take official institutions, for example. The White House, the monarchy, 10 Downing Street and other government departments are formal, traditional and important organisations. If the copy on their websites were written in a typeface like Cooper Black, it would erase any authority and respect that they were due. They need people to take them seriously and trust them, and part of the way to do this is to have a typeface that represents those values.

It works both ways though. If Innocent, Threadless or other fun companies used traditional typefaces, they wouldn’t be accurate reflections of their core values, brand and personality. They are better positioned to use friendly, informal and modern typefaces. But still never Comic Sans.

Tone of voice

Closely tied to this is tone of voice, my absolute bugbear on the web. Tone of voice isn’t what is said but, rather, how it is said. When we interact with others in person we don’t just listen to the words they say, but we also draw meaning from their body language, and pitch and tone of voice. Just because the web removes that face-to-face interaction with your audience it doesn’t mean you can’t have a tone of voice. 



Innocent pioneered the informal chatty tone of voice that so many others have since emulated, but unless it is representative of your company, then it’s not appropriate. It works for Innocent because the tone of voice is consistent across all the company’s materials, both online and offline. Ben and Jerry’s takes the same approach, as does Threadless, but maybe you need a more formal or corporate tone of voice. It really depends on what your business or service is and who it is for, and that is why I think LoveFilm has it all wrong. 

LoveFilm offers a film and game rental service, something fun for people in their downtime. While they aren’t particularly stuffy, neither is their tone of voice very friendly or informal, which is what I would expect from a service like theirs. The reason they have it wrong is in the language they use and the way their sentences are constructed.

This is the first time we’ve discussed language because, on the whole, designing the invisible isn’t concerned with language at all. But that doesn’t mean that these strands can’t still elicit an emotional response in users. Jon Tan quoted Dr Mazviita Chirimuuta in his New Adventures in Web Design talk in January 2011:


	Although there is no absolute separation between language and emotion, there will still be countless instances where you have emotional response without verbal input or linguistic cognition. In general language is not necessary for emotion.


This is even more pertinent when the emotions evoked are connected to people’s culture, surroundings and way of life. It makes design personal, something that audiences can connect with at more than just face value but, rather, on a subliminal or, indeed, invisible level. 

It also means that when you are asked the inevitable question of why – why is blue the dominant colour? why have you used that typeface? why don’t we sound like Innocent? – you will have a rationale behind each design decision that can explain what story you are telling, how you discovered the story and how it is targeted at the core audience.

Research

This is where research plays a vital role in the project cycle. If you don’t know and understand your audience then you don’t know what story to design. Every project lends itself to some level of research, but how in-depth and what methods are most appropriate will be dictated by project requirements and budget restrictions – but do your research. 

Even if you think you know your audience, it doesn’t hurt to research and reaffirm that because cultures and society do change, albeit slowly, but they can change. So ask questions at the start of the project during the research phase:


	What do different colours mean for your audience’s culture?
	Do the typeface and tone of voice appeal to the demographic?
	Does the brand identity represent the values and personality of your service?
	Are there any social, political or religious significances associated with your audience that you need to take into consideration so you don’t offend them?


Ask questions, understand your audience, design your story based on these insights, and create better user experiences in context that have good, solid storytelling at their heart.

286,Defending the Perimeter Against Web Widgets,"On July 14, 1789, citizens of Paris stormed the Bastille, igniting a revolution that toppled the French monarchy. On July 14 of this year, there was a less dramatic (though more tweeted) takedown: The Deck network, which delivers advertising to some of the most popular web design and culture destinations, was down for about thirty minutes. During this period, most partner sites running ads from The Deck could not be viewed as result.

A few partners were unaffected (aside from not having an ad to display). Fortunately, Dribbble, was one of them. In this article, I’ll discuss outages like this and how to defend against them. But first, a few qualifiers: The Deck has been rock solid – this is the only downtime we’ve witnessed since joining in June. More importantly, the issues in play are applicable to any web widget you might add to your site to display third-party content.

Down and out

Your defense is only as good as its weakest link. Web pages are filled with links, some of which threaten the ability of your page to load quickly and correctly. If you want your site to work when external resources fail, you need to identify the weak links on your site. In this article, we’ll talk about web widgets as a point of failure and defensive JavaScript techniques for handling them.

Widgets 101

Imagine a widget that prints out a Pun of the Day on your site. A simple technique for both widget provider and consumer is for the provider to expose a URL:

http://widgetjonesdiary.com/punoftheday.js

which returns a JavaScript file like this:

document.write(""<h2>The Pun of the Day</h2><p>Where do frogs go for beers after work? Hoppy hour!</p>"");

The call to document.write() injects the string passed into the document where it is called. So to display the widget on your page, simply add an external script tag where you want it to appear:

<div class=""punoftheday"">
  <script src=""http://widgetjonesdiary.com/punoftheday.js""></script>
  <!-- Content appears here as output of script above -->
</div>

This approach is incredibly easy for both provider and consumer. But there are implications…

document.write()… or wrong?

As in the example above, scripts may perform a document.write() to inject HTML. Page rendering halts while a script is processed so any output can be inlined into the document. Therefore, page rendering speed depends on how fast the script returns the data. If an external JavaScript widget hangs, so does the page content that follows. It was this scenario that briefly stalled partner sites of The Deck last summer.

The elegant solution

To make our web widget more robust, calls to document.write() should be avoided. This can be achieved with a technique called JSONP (AKA JSON with padding). In our example, instead of writing inline with document.write(), a JSONP script passes content to a callback function:

publishPun(""<h2>Pun of the Day</h2><p>Where do frogs go for beers after work? Hoppy hour!</p>"");

Then, it’s up to the widget consumer to implement a callback function responsible for displaying the content. Here’s a simple example where our callback uses jQuery to write the content into a target <div>:

<!-- Where widget content should appear -->
<div class=""punoftheday""></div>

…


<br />
function publishPun(content) {
  $(&#8216;.punoftheday&#8217;).html(content); // Writes content display location<br />
}<br />




View Example 1

Even if the widget content appears at the top of the page, our script can be included at the bottom so it’s non-blocking: a slow response leaves page rendering unaffected. It simply invokes the callback which, in turn, writes the widget content to its display destination.

The hack

But what to do if your provider doesn’t support JSONP? This was our case with The Deck. Returning to our example, I’m reminded of computer scientist David Wheeler’s statement, “All problems in computer science can be solved by another level of indirection… Except for the problem of too many layers of indirection.”

In our case, the indirection is to move the widget content into position after writing it to the page. This allows us to place the widget <script> tag at the bottom of the page so rendering won’t be blocked, but still display the widget in the target. The strategy:


	Load widget content into a hidden <div> at the bottom of the page.
	Move the loaded content from the hidden <div> to its display location.


and the code:

<!-- Where widget content should appear -->
<div class=""punoftheday""></div>

…



  
  



<br />
$(&#8216;.punoftheday&#8217;).append($(&#8216;.loading-dock&#8217;).children(&#8216;:gt(0)&#8217;));<br />

View Example 2

After the external punoftheday.js script has processed, the rendered HTML will look as follows:

<div class=""loading-dock hidden"">
  <script src=""http://widgetjonesdiary.com/punoftheday.js""></script>
  <h2>Pun of the Day</h2>
  <p>Where do frogs go for beers after work? Hoppy hour!</p>
</div>

The ‘loading-dock’ <div> now includes the widget content, albeit hidden from view (if we’ve styled the ‘hidden’ class with display: none). There’s just one more step: move the content to its display destination. This line of jQuery (from above) does the trick:

$('.punoftheday').append($('.loading-dock').children(':gt(0)'));

This selects all child elements in the ‘loading-doc’ <div> except the first – the widget <script> tag which generated it – and moves it to the display destination. Worth noting is the :gt(0) jQuery selector extension, which allows us to exclude the first (in a 0-based array) child element – the widget <script> tag – from selection.

Since all of this happens at the bottom of the page, just before the </body> tag, no rendering has to wait on the external widget script. The only thing that fails if our widget hangs is… the widget itself. Our weakest link has been strengthened and so has our site.

283,"CSS3 Patterns, Explained","Many of you have probably seen my CSS3 patterns gallery. It became very popular throughout the year and it showed many web developers how powerful CSS3 gradients really are. But how many really understand how these patterns are created? The biggest benefit of CSS-generated backgrounds is that they can be modified directly within the style sheet. This benefit is void if we are just copying and pasting CSS code we don’t understand. We may as well use a data URI instead.

Important note

In all the examples that follow, I’ll be using gradients without a vendor prefix, for readability and brevity. However, you should keep in mind that in reality you need to use all the vendor prefixes (-moz-, -ms-, -o-, -webkit-) as no browser currently implements them without a prefix. Alternatively, you could use -prefix-free and have the current vendor prefix prepended at runtime, only when needed.

The syntax described here is the one that browsers currently implement. The specification has since changed, but no browser implements the changes yet. If you are interested in what is coming, I suggest you take a look at the dev version of the spec.

If you are not yet familiar with CSS gradients, you can read these excellent tutorials by John Allsopp and return here later, as in the rest of the article I assume you already know the CSS gradient basics:


	CSS3 Linear Gradients
	CSS3 Radial Gradients


The main idea

I’m sure most of you can imagine the background this code generates:

background: linear-gradient(left, white 20%, #8b0 80%);

It’s a simple gradient from one color to another that looks like this:

 See this example live

As you probably know, in this case the first 20% of the container’s width is solid white and the last 20% is solid green. The other 60% is a smooth gradient between these colors. Let’s try moving these color stops closer to each other:

background: linear-gradient(left, white 30%, #8b0 70%);

 See this example live

background: linear-gradient(left, white 40%, #8b0 60%);

 See this example live

background: linear-gradient(left, white 50%, #8b0 50%);

 See this example live

Notice how the gradient keeps shrinking and the solid color areas expanding, until there is no gradient any more in the last example. We can even adjust the position of these two color stops to control where each color abruptly changes into another:

background: linear-gradient(left, white 30%, #8b0 30%);

 See this example live

background: linear-gradient(left, white 90%, #8b0 90%);

 See this example live

What you need to take away from these examples is that when two color stops are at the same position, there is no gradient, only solid colors. Even without going any further, this trick is useful for a number of different use cases like faux columns or the effect I wanted to achieve in my homepage or the -prefix-free page where the background is only shown on one side and hidden on the other:



Combining with background-size

We can do wonders, however, if we combine this with the CSS3 background-size property:

background: linear-gradient(left, white 50%, #8b0 50%);
background-size: 100px 100px;

 See this example live

And there it is. We just created the simplest of patterns: (vertical) stripes. We can remove the first parameter (left) or replace it with top and we’ll get horizontal stripes. However, let’s face it: Horizontal and vertical stripes are kinda boring. Most stripey backgrounds we see on the web are diagonal. So, let’s try doing that.

Our first attempt would be to change the angle of the gradient to something like 45deg. However, this results in an ugly pattern like this: 

 See this example live

Before reading on, think for a second: why didn’t this produce the desired result? Can you figure it out?

The reason is that the gradient angle rotates the gradient inside each tile, not the tiled background as a whole. However, didn’t we have the same problem the first time we tried to create diagonal stripes with an image? And then we learned that every stripe has to be included twice, like so:



So, let’s try to create that effect with CSS gradients. It’s essentially what we tried before, but with more color stops:

background: linear-gradient(45deg, white 25%,
    #8b0 25%, #8b0 50%, 
    white 50%, white 75%, 
    #8b0 75%);
background-size:100px 100px;

 See this example live

And there we have our stripes! An easy way to remember the order of the percentages and colors it is that you always have two of the same in succession, except the first and last color.

Note: Firefox for Mac also needs an additional 100% color stop at the end of any pattern with more than two stops, like so: ..., white 75%, #8b0 75%, #8b0). The bug was reported in February 2011 and you can vote for it and track its progress at Bugzilla.

Unfortunately, this is essentially a hack and we will realize that if we try to change the gradient angle to 60deg:

 See this example live

Not that maintainable after all, eh? Luckily, CSS3 offers us another way of declaring such backgrounds, which not only helps this case but also results in much more concise code:

background: repeating-linear-gradient(60deg, white, white 35px, #8b0 35px, #8b0 70px);

 See this example live

In this case, however, the size has to be declared in the color stop positions and not through background-size, since the gradient is supposed to cover the entire container. You might notice that the declared size is different from the one specified the previous way. This is because the size of the stripes is measured differently: in the first example we specify the dimensions of the tile itself; in the second, the width of the stripes (35px), which is measured diagonally.

Multiple backgrounds

Using only one gradient you can create stripes and that’s about it. There are a few more patterns you can create with just one gradient (linear or radial) but they are more or less boring and ugly. Almost every pattern in my gallery contains a number of different backgrounds. For example, let’s create a polka dot pattern:

background: radial-gradient(circle, white 10%, transparent 10%),
radial-gradient(circle, white 10%, black 10%) 50px 50px;
background-size:100px 100px;

 See this example live

Notice that the two gradients are almost the same image, but positioned differently to create the polka dot effect. The only difference between them is that the first (topmost) gradient has transparent instead of black. If it didn’t have transparent regions, it would effectively be the same as having a single gradient, as the topmost gradient would obscure everything beneath it.

There is an issue with this background. Can you spot it?

This background will be fine for browsers that support CSS gradients but, for browsers that don’t, it will be transparent as the whole declaration is ignored. We have two ways to provide a fallback, each for different use cases. We have to either declare another background before the gradient, like so:

background: black;
background: radial-gradient(circle, white 10%, transparent 10%),
radial-gradient(circle, white 10%, black 10%) 50px 50px;
background-size:100px 100px;

or declare each background property separately:

background-color: black;
background-image: radial-gradient(circle, white 10%, transparent 10%),
radial-gradient(circle, white 10%, transparent 10%);
background-size:100px 100px;
background-position: 0 0, 50px 50px;

The vigilant among you will have noticed another change we made to our code in the last example: we altered the second gradient to have transparent regions as well. This way background-color serves a dual purpose: it sets both the fallback color and the background color of the polka dot pattern, so that we can change it with just one edit. Always strive to make code that can be modified with the least number of edits. You might think that it will never be changed in that way but, almost always, given enough time, you’ll be proved wrong.

We can apply the exact same technique with linear gradients, in order to create checkerboard patterns out of right triangles:

background-color: white;
background-image: linear-gradient(45deg, black 25%, transparent 25%, transparent 75%, black 75%), 
linear-gradient(45deg, black 25%, transparent 25%, transparent 75%, black 75%);
background-size:100px 100px;
background-position: 0 0, 50px 50px;

 See this example live

Using the right units

Don’t use pixels for the sizes without any thought. In some cases, ems make much more sense. For example, when you want to make a lined paper background, you want the lines to actually follow the text. If you use pixels, you have to change the size every time you change font-size. If you set the background-size in ems, it will naturally follow the text and you will only have to update it if you change line-height.

Is it possible?

The shapes that can be achieved with only one gradient are:


	stripes
	right triangles
	circles and ellipses
	semicircles and other shapes formed from slicing ellipses horizontally or vertically


You can combine several of them to create squares and rectangles (two right triangles put together), rhombi and other parallelograms (four right triangles), curves formed from parts of ellipses, and other shapes.

Just because you can doesn’t mean you should

Technically, anything can be crafted with these techniques. However, not every pattern is suitable for it. The main advantages of this technique are:


	no extra HTTP requests
	short code
	human-readable code (unlike data URIs) that can be changed without even leaving the CSS file.


Complex patterns that require a large number of gradients are probably better left to SVG or bitmap images, since they negate almost every advantage of this technique:


	they are not shorter
	they are not really comprehensible – changing them requires much more effort than using an image editor


They still save an HTTP request, but so does a data URI.

I have included some very complex patterns in my gallery, because even though I think they shouldn’t be used in production (except under very exceptional conditions), understanding how they work and coding them helps somebody understand the technology in much more depth.

Another rule of thumb is that if your pattern needs shapes to obscure parts of other shapes, like in the star pattern or the yin yang pattern, then you probably shouldn’t use it. In these patterns, changing the background color requires you to also change the color of these shapes, making edits very tedious.

If a certain pattern is not practicable with a reasonable amount of CSS, that doesn’t mean you should resort to bitmap images. SVG is a very good alternative and is supported by all modern browsers.

Browser support

CSS gradients are supported by Firefox 3.6+, Chrome 10+, Safari 5.1+ and Opera 11.60+ (linear gradients since Opera 11.10). Support is also coming in Internet Explorer when IE10 is released. You can get gradients in older WebKit versions (including most mobile browsers) by using the proprietary -webkit-gradient(), if you really need them.

Epilogue

I hope you find these techniques useful for your own designs. If you come up with a pattern that’s very different from the ones already included, especially if it demonstrates a cool new technique, feel free to send a pull request to the github repo of the patterns gallery. Also, I’m always fascinated to see my techniques put in practice, so if you made something cool and used CSS patterns, I’d love to know about it!

271,Creating Custom Font Stacks with Unicode-Range,"Any web designer or front-end developer worth their salt will be familiar with the CSS @font-face rule used for embedding fonts in a web page. We’ve all used it — either directly in our code ourselves, or via one of the web font services like Fontdeck, Typekit or Google Fonts.

If you’re like me, however, you’ll be used to just copying and pasting in a specific incantation of lines designed to get different formats of fonts working in different browsers, and may not have really explored all the capabilities of @font-face properties as defined by the spec.

One such property — the unicode-range descriptor — sounds pretty dull and is easily overlooked. It does, however, have some fairly interesting possibilities when put to use in creative ways.

Unicode-range

The unicode-range descriptor is designed to help when using fonts that don’t have full coverage of the characters used in a page. By adding a unicode-range property to a @font-face rule it is possible to specify the range of characters the font covers. 

@font-face {
    font-family: BBCBengali;
    src: url(fonts/BBCBengali.ttf) format(""opentype"");
    unicode-range: U+00-FF;
}

In this example, the font is to be used for characters in the range of U+00 to U+FF which runs from the unexciting control characters at the start of the Unicode table (symbols like the exclamation mark start at U+21) right through to ÿ at U+FF – the extent of the Basic Latin character range.

By adding multiple @font-face rules for the same family but with different ranges, you can build up complete coverage of the characters your page uses by using different fonts.

When I say that it’s possible to specify the range of characters the font covers, that’s true, but what you’re really doing with the unicode-range property is declaring which characters the font should be used for. This becomes interesting, because instead of merely working with the technical constraints of available characters in a given font, we can start picking and choosing characters to use and selectively mix fonts together.

The best available ampersand

A few years back, Dan Cederholm wrote a post encouraging designers to use the best available ampersand. Dan went on to outline how this can be achieved by wrapping our ampersands in a <span> element with a class applied:

<span class=""amp"">&</span>

A CSS rule can then be written to select the <span> and apply a different font:

span.amp {
    font-family: Baskerville, Palatino, ""Book Antiqua"", serif;
}

That’s a perfectly serviceable technique, but the drawbacks are clear — you have to add extra markup which is borderline presentational, and you also have to be able to add that markup, which isn’t always possible when working with a CMS.

Perhaps we could do this with unicode-range.

A better best available ampersand

The Unicode code point for an ampersand is U+26, so the ampersand font stack above can be created like so:

@font-face {
    font-family: 'Ampersand';
    src: local('Baskerville'), local('Palatino'), local('Book Antiqua');
    unicode-range: U+26;
}

What we’ve done here is specify a new family called Ampersand and created a font stack for it with the user’s locally installed copies of Baskerville, Palatino or Book Antiqua. We’ve then limited it to a single character range — the ampersand. Of course, those don’t need to be local fonts — they could be web font files, too. If you have a font with a really snazzy ampersand, go for your life.

We can then use that new family in a regular font stack.

h1 {
    font-family: Ampersand, Arial, sans-serif;
}

With this in place, any <h1> elements in our page will use the Ampersand family (Baskerville, Palatino or Book Antiqua) for ampersands, and Arial for all other characters. If the user doesn’t have any of the Ampersand family fonts available, the ampersand will fall back to the next item in the font stack, Arial.

You didn’t think it was that easy, did you?

Oh, if only it were so. The problem comes, as ever, with the issue of browser support. The unicode-range property has good support in WebKit browsers (like Safari and Chrome, and the browsers on most popular smartphone platforms) and in recent versions of Internet Explorer. The big stumbling block comes in the form of Firefox, which has no support at all.

If you’re familiar with how CSS works when it comes to unsupported properties, you’ll know that if a browser encounters a property it doesn’t implement, it just skips that declaration and moves on to the next. That works perfectly for things like border-radius — if the browser can’t round off the corners, the declaration is skipped and the user sees square corners instead. Perfect.

Less perfect when it comes to unicode-range, because if no range is specified then the default is that the font is applied for all characters — the whole range. If you’re using a fancy font for flamboyant ampersands, you probably don’t want that applied to all your text if unicode-range isn’t supported. That would be bad. Really bad.

Ensuring good fallbacks

As ever, the trick is to make sure that there’s a sensible fallback in place if a browser doesn’t have support for whatever technology you’re trying to use. This is where being a super nerd about understanding the spec you’re working with really pays off.

We can make use of the rules of the CSS cascade to make sure that if unicode-range isn’t supported we get a sensible fallback font. What would be ideal is if we were able to follow up the @font-face rule with a second rule to override it if Unicode ranges aren’t implemented.

@font-face {
    font-family: 'Ampersand';
    src: local('Baskerville'), local('Palatino'), local('Book Antiqua');
    unicode-range: U+26;
}
@font-face {
    font-family: 'Ampersand';
    src: local('Arial');
}

In theory, this code should make sense for all browsers. For those that support unicode-range the two rules become cumulative. They specify different ranges for the same family, and in WebKit browsers this has the expected result of using Arial for most characters, but Baskerville and friends for the ampersand. For browsers that don’t have support, the second rule should just supersede the first, setting the font to Arial. 

Unfortunately, this code causes current versions of Firefox to freak out and use the first rule, applying Baskerville to the entire range. That’s both unexpected and unfortunate. Bad Firefox. On your rug.

If that doesn’t work, what can we do? Well, we know that if given a unicode-range Firefox will ignore the range and apply the font to all characters. That’s really what we’re trying to achieve. So what if we specified a range for the fallback font, but made sure it only covers some obscure high-value Unicode character we’re never going to use in our page? Then it wouldn’t affect the outcome for browsers that do support ranges.

@font-face {
    font-family: 'Ampersand';
    src: local('Baskerville'), local('Palatino'), local('Book Antiqua');
    unicode-range: U+26;
}
@font-face {
    /* Ampersand fallback font */
    font-family: 'Ampersand';
    src: local('Arial');
    unicode-range: U+270C;
}

By specifying a range on the fallback font, Firefox appears to correctly override the first based on the cascade sort order. Browsers that do support ranges take the second rule in addition, and apply Arial for that obscure character we’re not using in any of our pages — U+270C.

So we get our nice ampersands in browsers that support unicode-range and, thanks to our styling of an obscure Unicode character, the font falls back to a perfectly acceptable Arial in browsers that do not offer support. Perfect!

That obscure character, my friends, is what Unicode defines as the VICTORY HAND.

✌

So, how can we use this?

Ampersands are a neat trick, and it works well in browsers that support ranges, but that’s not really the point of all this. Styling ampersands is fun, but they’re only really scratching the surface. Consider more involved examples, such as substituting a different font for numerals, or symbols, or even caps. Things certainly begin to get a bit more interesting.

How do you know what the codes are for different characters? Richard Ishida has a handy online conversion tool available where you can type in the characters and get the Unicode code points out the other end.

Of course, the fact remains that browser support for unicode-range is currently limited, so any application needs to have fallbacks that you’re still happy for a significant proportion of your visitors to see. In some cases, such as dedicated pages for mobile devices in an HTML-based phone app, this is immediately useful as support in WebKit browsers is already very good. In other cases, you’ll have to use your own best judgement based on your needs and audience.

One thing to keep in mind is that if you’re using web fonts, the entire font will be downloaded even if only one character is used. That said, the font shouldn’t be downloaded if none of the characters within the Unicode range are present in a given page.

As ever, there are pros and cons to using unicode-range as well as varied but increasing support in browsers. It remains a useful tool to understand and have in your toolkit for when the right moment comes along.",2011,Drew McLellan,drewmclellan,2011-12-01T00:00:00+00:00,https://24ways.org/2011/creating-custom-font-stacks-with-unicode-range/,code
272,Crafting the Front-end,"Much has been spoken and written recently about the virtues of craftsmanship in the context of web design and development. It seems that we as fabricators of the web are finally tiring of seeking out parallels between ourselves and architects, and are turning instead to the fabled specialist artisans.

Identifying oneself as a craftsman or craftswoman (let’s just say craftsperson from here onward) will likely be a trend of early 2012. In this pre-emptive strike, I’d like to expound on this movement as I feel it pertains to front-end development, and encourage care and understanding of the true qualities of craftsmanship (craftspersonship).

The core values

I’ll begin by defining craftspersonship. What distinguishes a craftsperson from a technician? Dictionaries tend to define a craftsperson as one who possesses great skill in a chosen field. The badge of a craftsperson for me, though, is a very special label that should be revered and used sparingly, only where it is truly deserved. A genuine craftsperson encompasses a few other key traits, far beyond raw skill, each of which must be learned and mastered.

A craftsperson has: 


	An appreciation of good work, in both the work of others and their own. And not just good as in ‘hey, that’s pretty neat’, I mean a goodness like a shining purity – the kind of good that feels right when you see it.
	A belief in quality at every level: every facet of the craftsperson’s product is as crucial as any other, without exception, even those normally hidden from view.
	Vision: an ability to visualize their path ahead, pre-empting the obstacles that may be encountered to plan a route around them.
	A preference for simplicity: an almost Bauhausesque devotion to undecorated functionality, with no unjustifiable parts included.
	Sincerity: producing work that speaks directly to its purpose with flawless clarity.


Only when you become a custodian of such values in your work can you consider calling yourself a craftsperson. Now let’s take a look at some steps we front-end developers can take on our journey of enlightenment toward craftspersonhood.

 Speaking of the craftsman’s journey, be sure to watch out for the video of The Standardistas’ stellar talk at the Build 2011 conference titled The Journey, which should be online sometime soon.

Building your own toolbox

My grandfather was a carpenter and trained as a young apprentice under a master. After observing and practising the many foundation theories, principles and techniques of carpentry, he was tasked with creating his own set of woodworking tools, which he would use and maintain throughout his career. By going through the process of having to create his own tools, he would be connected at the most direct level with every piece of wood he touched, his tools being his own creations and extensions of his own skilled hands. The depth of his knowledge of these tools must have surpassed the intricate as he fathered, used, cleaned and repaired them, day in and day out over many years.

And so it should be, ideally, with all crafts. We must understand our tools right down to the most fundamental level. I firmly believe that a level of true craftsmanship cannot be reached while there exists a layer that remains not wholly understood between a creator and his canvas. Of course, our tools as front-end developers are somewhat more complex than those of other crafts – it may seem reasonable to require that a carpenter create his or her own set of chisels, but somewhat less so to ask a front-end developer to code their own CSS preprocessor, or design their own computer.

However, it is still vitally important that you understand how your tools work. This is particularly critical when it comes to things like preprocessors, libraries and frameworks which aim to save you time by automating common processes and functions. For the most part, anything that saves you time is a Good Thing™ but it cannot be stressed enough that using tools like these in earnest should be avoided until you understand exactly what they are doing for you (and, to an extent, how they are doing it). 

In particular, you must understand any drawbacks to using your tools, and any shortcuts they may be taking on your behalf. I’m not suggesting that you steer clear of paid work until you’ve studied each of jQuery’s 9,266 lines of JavaScript source code but, all levity aside, it will further you on your journey to look at interesting or relevant bits of jQuery, and any other libraries you might want to use. Such libraries often directly link to corresponding sections of their source code on sites like GitHub from their official documentation. Better yet, they’re almost always written in high level languages (easy to read), so there’s no excuse not to don your pith helmet and go on something of an exploration. Any kind of tangential learning like this will drive you further toward becoming a true craftsperson, so keep an open mind and always be ready to step out of your comfort zone.

Downtime and tool honing

With any craft, it is essential to keep your tools in good condition, and a good idea to stay up-to-date with the latest equipment. This is especially true on the web, which, as we like to tell anyone who is still awake more than a minute after asking what it is that we do, advances at a phenomenal pace. A tool or technique that could be considered best practice this week might be the subject of haughty derision in a comment thread within six months.

I have little doubt that you already spend a chunk of time each day keeping up with the latest material from our industry’s finest Interblogs and Twittertubes, but do you honestly put aside time to collect bookmarks and code snippets from things you read into a slowly evolving toolbox? At @media in 2009, Simon Collison delivered a candid talk on his ‘Ultimate Package’. Those of us who didn’t flee the room anticipating a newfound and unwelcome intimacy with the contents of his trousers were shown how he maintained his own toolkit – a collection of files and folders all set up and ready to go for a new project. By maintaining a toolkit in this way, he has consistency across projects and a dependable base upon which to learn and improve.

The assembly and maintenance of such a personalized and familiar toolkit is probably as close as we will get to emulating the tool making stage of more traditional craft trades. Keep a master copy of your toolkit somewhere safe, making copies of it for new projects. When you learn of a way in which part of it can be improved, make changes to the master copy.

Simplicity through modularity

I believe that the user interfaces of all web applications should be thought of as being made up primarily of modular components. Modules in this context are patterns in design that appear repeatedly throughout the app. These can be small collections of elements, like a user profile summary box (profile picture, username, meta data), as well as atomic elements such as headings and list items.

Well-crafted front-end architectures have the ability to support this kind of repeating pattern as modules, with as close to no repetition of CSS (or JavaScript) as possible, and as close to no variations in HTML between instances as possible.

One of the most fundamental and well known tenets of software engineering is the DRY rule – don’t repeat yourself. It requires that “every piece of knowledge must have a single, unambiguous, authoritative representation within a system.” 

As craftspeople, we must hold this rule dear and apply it to the modules we have identified in our site designs. The moment you commit a second style definition for a module, the quality of your output (the front-end code) takes a huge hit. There should only ever be one base style definition for each distinct module or component. Keep these in a separate, sacred place in your CSS. I use a _modules.scss Sass include file, imported near the top of my main CSS files.

Be sure, of course, to avoid making changes to this file lightly, as the smallest adjustment can affect multiple pages (hint: keep a structure list of which modules are used on which pages). Avoid the inevitable temptation to duplicate code late in the project. Sticking to this rule becomes more important the more complex the codebase becomes.

If you can stick to this rule, using sensible class names and consistent HTML, you can reach a joyous, self-fulfilling plateau stage in each project where you are assembling each interface from your own set of carefully crafted building blocks.

Old school markup

Let’s take a step back. Before we fret about creating a divinely pure modular CSS framework, we need to know the site’s design and what it is made of. The best way to gain this knowledge is to go old school. Print out every comp, mockup, wireframe, sketch or whatever you have. If there are sections of pages that are hidden until some user action takes place, or if the page has multiple states, be sure that you have everything that could become visible to the user on paper.

Once you have your wedge of paper designs, lay out all the pages on the floor, or stick them to the wall if you can, arranging them logically according to the site hierarchy, by user journey, or whatever guidelines make most sense to you. Once you have the site laid out before you, study it for a while, familiarizing yourself with every part of every interface. This will eliminate nasty surprises late in the project when you realize you’ve duplicated something, or left an interface on the drawing board altogether.

Now that you know the site like it’s your best friend, get out your pens or pencils of choice and attack it. Mark it up like there’s no tomorrow. Pretend you’re a spy trying to identify communications from an enemy network hiding their messages in newspapers. Look for patterns and similarities, drawing circles around them. These are your modules. Start also highlighting the differences between each instance of these modules, working out which is the most basic or common type that will become the base definition from which all other representations are extended.

This simple but empowering exercise will equip you for your task of actually crafting, instead of just building, the front-end. Without the knowledge gained from this kind of research phase, you will be blundering forward, improvising as best you can, but ultimately making quality-compromising mistakes that could have been avoided.

For more on this theme, read Anna Debenham’s Front-end Style Guides which recommends a similar process, and the sublime idea of extending this into a guide to refer to during development and beyond.

Design homogeneity

Moving forward again, you now have your modules defined and things are looking good. I mentioned that many instances of these modules will carry minor differences. These differences must be given significant thinking time, and discussion time with your designer(s).

It should be common knowledge by now that successful software projects are not the product of distinct design and build phases with little or no bidirectional feedback. The crucial nature of the designer-developer relationship has been covered in depth this year by Paul Robert Lloyd, and a joint effort from both teams throughout the project lifecycle is pivotal to your ability to craft and ship successful products.

This relationship comes into play when you’re well into the development of the site, and you start noticing these differences between instances of modules (they’ll start to stand out very clearly to you and your carefully regimented modular CSS system). Before you start overriding your base styles, question the differences with the designer to work out why they exist. Perhaps they are required and are important to their context, but perhaps they were oversights from earlier design revisions, or simple mistakes.

The craftsperson’s gland

As you grow towards the levels of expertise and experience where you can proudly and honestly consider yourself a craftsperson, you will find that you steadily develop what initially feels like a kind of sixth sense. I think of it more as a new hormonal gland, secreting into your bloodstream a powerful messenger chemical that can either reward or punish your brain. This gland is connected directly to your core understanding of what good quality work looks and feels like, an understanding that itself improves with experience. 

This gland will make itself known to you in two ways. First, when you solve a problem in a beautifully elegant way with clean and unobtrusive code that looks good and just feels right, your craftsperson’s gland will ooze something delicious that makes your brain and soul glow from the inside out. You will beam triumphantly at the succinct lines of code on your computer display before bounding outside with a spring in your step to swim up glittering rainbows and kiss soft fluffy puppies.

The second way that you may become aware of your craftsperson’s gland, though, is somewhat less pleasurable. In an alternate reality, your parallel self is faced with the same problem, but decides to take a shortcut and get around it by some dubious means – the kind of technical method that the words hack, kludge and bodge are reserved for. As soon as you have done this, or even as you are doing it, your craftsperson’s gland will damn well let you know that you took the wrong fork in the road. As your craftsperson’s gland begins to secrete a toxic pus, you will at first become entranced into a vacant stare at the monstrous mess you are considering unleashing upon your site’s visitors, before writhing in the horrible agony of an itch that can never be scratched, and a feeling of being coated with the devil’s own deep and penetrating filth that no shower will ever cleanse.

Perhaps I exaggerate slightly, but it is no overstatement to suggest that you will find yourself being guided by proverbial angels and demons perched on opposite shoulders, or a whispering voice inside your head. If you harness this sense, sharpening it as if it were another tool in your kit and letting it guide or at least advise your decision making, you will transcend the rocky realm of random trial and error when faced with problems, and tend toward the right answers instinctively.

This gland can also empower your ability to assess your own work, becoming a judge before whom all your work is cross-examined. A good craftsperson regularly takes a step back from their work, and questions every facet of their product for its precise alignment with their core values of quality and sincerity, and even the very necessity of each component.

The wrapping

By now, you may be thinking that I take this kind of thing far too seriously, but to terrify you further, I haven’t even shared the half of it. Hopefully, though, this gives you an idea of the kind of levels of professionalism and dedication that it should take to get you on your way to becoming a craftsperson. It’s a level of accomplishment and ability toward which we all should strive, both for our personal fulfilment and the betterment of the products we use daily. I look forward to seeing your finely crafted work throughout 2012.",2011,Ben Bodien,benbodien,2011-12-24T00:00:00+00:00,https://24ways.org/2011/crafting-the-front-end/,process
275,Context First: Web Strategy in Four Handy Ws,"Many, many years ago, before web design became my proper job, I trained and worked as a journalist. I studied publishing in London and spent three fun years learning how to take a few little nuggets of information and turn them into a story. I learned a bunch of stuff that has all been a huge help to my design career. Flatplanning, layout, typographic theory. All of these disciplines have since translated really well to web design, but without doubt the most useful thing I learned was how to ask difficult questions.

Pretty much from day one of journalism school they hammer into you the importance of the Five Ws. Five disarmingly simple lines of enquiry that eloquently manage to provide the meat of any decent story. And with alliteration thrown in too. For a young journo, it’s almost too good to be true.

Who? What? Where? When? Why? It seems so obvious to almost be trite but, fundamentally, any story that manages to answer those questions for the reader is doing a pretty good job. You’ll probably have noticed feeling underwhelmed by certain news pieces in the past – disappointed, like something was missing. Some irritating oversight that really lets the story down. No doubt it was one of the Ws – those innocuous little suckers are generally only noticeable by their absence, but they sure get missed when they’re not there. 

Question everything

I’ve always been curious. An inveterate tinkerer with things and asker of dopey questions, often to the point of abject annoyance for anyone unfortunate enough to have ended up in my line of fire. So, naturally, the Five Ws started drifting into other areas of my life. I’d scrutinize everything, trying to justify or explain my rationale using these Ws, but I’d also find myself ripping apart the stuff that clearly couldn’t justify itself against the same criteria.

So when I started working as a designer I applied the same logic and, sure enough, the Ws pretty much mapped to the exact same needs we had for gathering requirements at the start of a project. It seemed so obvious, such a simple way to establish the purpose of a product. What was it for? Why we were making it? And, of course, who were we making it for? It forced clients to stop and think, when really what they wanted was to get going and see something shiny. Sometimes that was a tricky conversation to have, but it’s no coincidence that those who got it also understood the value of strategy and went on to have good solid products, while those that didn’t often ended up with arrogantly insular and very shiny but ultimately unsatisfying and expendable products. Empty vessels make the most noise and all that…

Content first

I was both surprised and pleased when the whole content first idea started to rear its head a couple of years back. Pleased, because without doubt it’s absolutely the right way to work. And surprised, because personally it’s always been the way I’ve done it – I wasn’t aware there was even an alternative way. Content in some form or another is the whole reason we were making the things we were making. I can’t even imagine how you’d start figuring out what a site needs to do, how it should be structured, or how it should look without a really good idea of what that content might be. It baffles me still that this was somehow news to a lot of people. What on earth were they doing? Design without purpose is just folly, surely?

It’s great to see the idea gaining momentum but, having watched it unfold, it occurred to me recently that although it’s fantastic to see a tangible shift in thinking – away from those bleak times, where making things up was somehow deemed an appropriate way to do things – there’s now a new bad guy in town.

With any buzzword solution of the moment, there’s always a catch, and it seems like some have taken the content first approach a little too literally. By which I mean, it’s literally the first thing they do. The project starts, there’s a very cursory nod towards gathering requirements, and off they go, cranking content. Writing copy, making video, commissioning illustrations.

All that’s happened is that the ‘making stuff up’ part has shifted along the line, away from layout and UI, back to the content. 

Starting is too easy

I can’t remember where I first heard that phrase, but it’s a great sentiment which applies to so much of what we do on the web. The medium is so accessible and to an extent disposable; throwing things together quickly carries far less burden than in any other industry. We’re used to tweaking as we go, changing bits, iterating things into shape. The ubiquitous beta tag has become the ultimate caveat, and has made the unfinished and unpolished acceptable. Of course, that can work brilliantly in some circumstances. Occasionally, a product offers such a paradigm shift it’s beyond the level of deep planning and prelaunch finessing we’d ideally like. But, in the main, for most client sites we work on, there really is no excuse not to do things properly. To ask the tricky questions, to challenge preconceptions and really understand the Ws behind the products we’re making before we even start. 

The four Ws

For product definition, only four of the five Ws really apply, although there’s a lot of discussion around the idea of when being an influencing factor. For example, the context of a user’s engagement with your product is something you can make a call on depending on the specifics of the project.

So, here’s my take on the four essential Ws. I’ll point out here that, of course, these are not intended to be autocratic dictums. Your needs may differ, your clients’ needs may differ, but these four starting points will get you pretty close to where you need to be.

Who 

It’s surprising just how many projects start without a real understanding of the intended audience. Many clients think they have an idea, but without really knowing – it’s presumptive at best, and we all know what presumption is the mother of, right? Of course, we can’t know our audiences in the same way a small shop owner might know their customers. But we can at least strive to find out what type of people are likely to be using the product. I’m not talking about deep user research. That should come later.

These are the absolute basics. What’s the context for their visit? How informed are they? What’s their level of comprehension? Are they able to self-identify and relate to categories you have created? I could go on, and it changes on a per-project basis. You’ll only find this out by speaking to them, if not in person, then indirectly through surveys, questionnaires or polls. The mechanism is less important than actually reaching out and engaging with them, because without that understanding it’s impossible to start to design with any empathy.

What

Once you become deeply involved directly with a product or service, it’s notoriously difficult to see things as an outsider would. You learn the thing inside and out, you develop shortcuts and internal phraseology. Colloquialisms creep in. You become too close. So it’s no surprise when clients sometimes struggle to explain what it is their product actually does in a way that others can understand.

Often products are complex but, really, the core reasons behind someone wanting to use that product are very simple. There’s a value proposition for the customer and, if they choose to engage with it, there’s a value exchange. If that proposition or exchange isn’t transparent, then people become confused and will likely go elsewhere. Make sure both your client and you really understand what that proposition is and, in turn, what the expected exchange should be. In a nutshell: what is the intended outcome of that engagement? Often the best way to do this is strip everything back to nothing. Verbosity is rife on the web. Just because it’s easy to create content, that shouldn’t be a reason to do so. Figure out what the value proposition is and then reintroduce content elements that genuinely help explain or present that to a level that is appropriate for the audience. 

Why 

In advertising, they talk about the truths behind a product or service. Truths can be both tangible or abstract, but the most important part is the resonance those truths hit with a customer. In a digital product or service those truths are often exposed as benefits. Why is this what I need? Why will it work for me? Why should I trust you? The why is one of the more fluffy Ws, yet it’s such an important one to nail. Clients can get prickly when you ask them to justify the why behind their product, but it’s a fantastic way to make sure the value proposition is clear, realistic and meets with the expectations of both client and customer.

It’s our job as designers to question things: we’re not just a pair of hands for clients. Just recently I spoke to a potential client about a site for his business. I asked him why people would use his product and also why his product seemed so fractured in its direction. He couldnt answer that question so, instead of ploughing on regardless, he went back to his directors and is now re-evaluating that business. It was awkward but he thanked me and hopefully he’ll have a better product as a result.

Where

In this instance, where is not so much a geographical thing, although in some cases that level of context may indeed become a influencing factor… The where we’re talking about here is the position of the product in relation to others around it. By looking at competitors or similar services around the one you are designing, you can start to get a sense for many of the things that are otherwise hard to pin down or have yet to be defined. For example, in a collection of sites all selling cars, where does yours fit most closely? Where are the overlaps? How are they communicating to their customers? How is the product range presented or categorized?

It’s good to look around and see how others are doing it. Not in a quest for homogeneity but more to reference or to avoid certain patterns that may or may not make sense for your own particular product. Clients often strive to be different for the sake of it. They feel they need to provide distinction by going against the flow a bit. We know different. We know users love convention. They embrace familiar mental models. They’re comfortable with things that they’ve experienced elsewhere. By showing your client that position is a vital part of their strategy, you can help shape their product into something great. 

To conclude

So there we have it – the four Ws. Each part tells a different and vital part of the story you need to be able to make a really good product. It might sound like a lot of work, particularly when the client is breathing down your neck expecting to see things, but without those pieces in place, the story you’re building your product on, and the content that you’re creating to form that product can only ever fit into one genre.

280,Conditional Loading for Responsive Designs,"On the eighteenth day of last year’s 24 ways,  Paul Hammond  wrote a great article called Speed Up Your Site with Delayed Content. He outlined a technique for loading some content — like profile avatars — after the initial page load. This gives you a nice performance boost.

There’s another situation where this kind of delayed loading could be really handy: mobile-first responsive design.

Responsive design combines three techniques:


	a fluid grid
	flexible images
	media queries


At first, responsive design was applied to existing desktop-centric websites to allow the layout to adapt to smaller screen sizes. But more recently it has been combined with another innovative approach called mobile first.

Rather then starting with the big, bloated desktop site and then scaling down for smaller devices, it makes more sense to start with the constraints of the small screen and then scale up for larger viewports. Using this approach, your layout grid, your large images and your media queries are applied on top of the pre-existing small-screen design. It’s taking progressive enhancement to the next level.

One of the great advantages of the mobile-first approach is that it forces you to really focus on the core content of your page. It might be more accurate to think of this as a content-first approach. You don’t have the luxury of sidebars or multiple columns to fill up with content that’s just nice to have rather than essential.

But what happens when you apply your media queries for larger viewports and you do have sidebars and multiple columns? Well, you can load in that nice-to-have content using the same kind of Ajax functionality that Paul described in his article last year. The difference is that you first run a quick test to see if the viewport is wide enough to accommodate the subsidiary content. This is conditional delayed loading.

Consider this situation: I’ve published an article about cats and I’d like to include relevant cat-related news items in the sidebar …but only if there’s enough room on the screen for a sidebar.

I’m going to use Google’s News API to return the search results. This is the ideal time to use delayed loading: I don’t want a third-party service slowing down the rendering of my page so I’m going to fire off the request after my document has loaded.

Here’s an example of the kind of Ajax function that I would write:

var searchNews = function(searchterm) {
	var elem = document.createElement('script');
	elem.src = 'http://ajax.googleapis.com/ajax/services/search/news?v=1.0&q='+searchterm+'&callback=displayNews';
	document.getElementsByTagName('head')[0].appendChild(elem);
};

I’ve provided a callback function called displayNews that takes the JSON result of that Ajax request and adds it an element on the page with the ID newsresults:

var displayNews = function(news) {
	var html = '',
	items = news.responseData.results,
	total = items.length;
	if (total>0) {
		for (var i=0; i<total; i++) {
			var item = items[i];
			html+= '<article>';
			html+= '<a href=""'+item.unescapedUrl+'"">';
			html+= '<h3>'+item.titleNoFormatting+'</h3>';
			html+= '</a>';
			html+= '<p>';
			html+= item.content;
			html+= '</p>';
			html+= '</article>';
		}
		document.getElementById('newsresults').innerHTML = html;
	}
};

Now, I can call that function at the bottom of my document:

<script>
    searchNews('cats');
</script>

If I only want to run that search when there’s room for a sidebar, I can wrap it in an if statement:

<script>
if (document.documentElement.clientWidth > 640) {
    searchNews('cats');
}
</script>

If the browser is wider than 640 pixels, that will fire off a search for news stories about cats and put the results into the newsresults element in my markup:

<div id=""newsresults"">
    <!-- search results go here -->
</div>

This works pretty well but I’m making an assumption that people with small-screen devices wouldn’t be interested in seeing that nice-to-have content. You know what they say about assumptions: they make an ass out of you and umptions. I should really try to give everyone at least the option to get to that extra content:

<div id=""newsresults"">
    <a href=""http://www.google.com/search?q=cats&tbm=nws"">Search Google News</a>
</div>

See the result

Visitors with small-screen devices will see that link to the search results; visitors with larger screens will get the search results directly.

I’ve been concentrating on HTML and JavaScript, but this technique has consequences for content strategy and information architecture. Instead of thinking about possible page content in a binary way as either ‘on the page’ or ‘not on the page’, conditional loading introduces a third ‘it’s complicated’ option.

This was just a simple example but I hope it illustrates that conditional loading could become an important part of the content-first responsive design approach.",2011,Jeremy Keith,jeremykeith,2011-12-02T00:00:00+00:00,https://24ways.org/2011/conditional-loading-for-responsive-designs/,ux
285,"Composing the New Canon: Music, Harmony, Proportion","Ohne Musik wäre das Leben ein Irrtum
—Friedrich NIETZSCHE, Götzen-Dämmerung, Sprüche und Pfeile 33, 1889


Somehow, music is hardcoded in human beings. It is something we understand and respond to without prior knowledge. Music exercises the emotions and our imaginative reflex, not just our hearing. It behaves so much like our emotions that music can seem to symbolize them, to bear them from one person to another. Not surprisingly, it conjures memories: the word music derives from Greek μουσική (mousike), art of the Muses, whose mythological mother was Mnemosyne, memory. But it can also summon up the blood, console the bereaved, inspire fanaticism, bolster governments and dissenters alike, help us learn, and make web designers dance. And what would Christmas be without music?

Music moves us, often in ways we can’t explain. By some kind of alchemy, music frees us from the elaborate nuisance and inadequacy of words. Across the world and throughout recorded history – and no doubt well before that – people have listened and made (and made out to) music.


	[I]t appears probable that the progenitors of man, either the males or females or both sexes, before acquiring the power of expressing their mutual love in articulate language, endeavoured to charm each other with musical notes and rhythm.
—Charles DARWIN, The Descent of Man, and Selection in Relation to Sex, 1871


It’s so integral to humankind, we’ve sent it into space as a totem for who we are. (Who knows? It might be important.) Music is essential, a universal compulsion; as Nietzsche wrote, without music life would be a mistake.

Music, design and web design

There are some obvious and notable similarities between music and visual design. Both can convey mood and evoke emotion but, even under close scrutiny, how they do that remains to a great extent mysterious. Each has formal qualities or parts that can be abstracted, analysed and discussed, often using the same terminology: composition, harmony, rhythm, repetition, form, theme; even colour, texture and tone.

A possible reason for these shared aspects is that both visual design and music are means to connect with people in deep and lasting ways. Furthermore, I believe the connections to be made can complement direct emotional appeal. Certain aesthetic qualities in music work on an unconscious and, it could be argued, universal level. Using musical principles in our designs, then, can help provide the connectedness between content, device and user that we now seek as web designers.

Yet, when we talk about music and web design, the conversation is almost always about the music designers listen to while working, a theme finding its apotheosis in Designers.MX. Sometimes, articles in that dreary list format seek inspiration from music industry websites. There’s even a service offering pre-templated web designs for bands, and at least one book surveyed the landscape back in 2006. Occasionally, discussions broaden somewhat into whether and how different kinds of music can inspire and influence the design work we produce.

Such enquiries, it seems to me, are beside the point. Do I really design differently when I listen to Bach rather than Bacharach? Will the barely restrained energy of Count Basie’s The Kid from Red Bank mean I choose a lively colour palette, and rural, autumnal shades when inspired by Fleet Foxes? Mahler means a thirteen-column layout? Gillian Welch leads to distressed black and white photography? While reflecting the importance we place in music and how it seems to help us in our work, surveys on musical taste and lists of favourite artists fail to recognize that some of the fundamental aesthetic characteristics of music can be adapted and incorporated into modern web design.

Antiphonal geometry

Over recent years, web designers have embraced grid systems as powerful tools to help create good-looking and intuitive user experiences. With the advent of responsive design, these grids and their contents must adapt to the different screen sizes and properties of all kinds of user devices. Finding and using grid values that can scale well and retain or enhance their proportions and relationships while making the user experience meaningful in several different contexts is more important than ever.

In print, this challenge has always started with the dimensions and proportions of the page. Content can thereby be made to belong inside the page and be bound to it. And music has been used for centuries to further this aim. As Robert Bringhurst says in The Elements of Typographical Style:


	Indeed, one of the simplest of all systems of page proportions is based on the familiar intervals of the diatonic scale. Pages that embody these basic musical proportions have been in common use in Europe for more than a thousand years.


Very well. But while he goes on to list (from the full chromatic scale, rather than just diatonic) the proportions and the musical intervals they’re based on, Bringhurst fails to mention what they’re ratios of or their potential effects. Shame. In his favour, however, he later touches on how proportions in print might be considered to work:


	The page is a piece of paper. It is also a visible and tangible proportion, silently sounding the thoroughbass of the book. On it lies the textblock, which must answer to the page. The two together – page and textblock – produce an antiphonal geometry. That geometry alone can bond the reader to the book. Or conversely, it can put the reader to sleep, or put the reader’s nerves on edge, or drive the reader away.


So what does Bringhurst mean by antiphonal geometry, a phrase that marries the musical to the spatial? By stating that the textblock “must answer to the page”, the implication is that the relationship between the proportions of the page and the shape of the textblock printed on it embodies a spatial (geometrical) call-and-response (antiphony) that can be appealing or not.

Boulton’s new canon

But, as Mark Boulton has pointed out, on the web “there are no edges. There are no ‘pages’. We’ve made them up.” So, what is to be done? In January 2011 at the New Adventures in Web Design conference, Boulton presented his vision of a new canon of web design, a set of principles to guide us as we design the web. There are three overlapping tenets:


	design from the content out
	create connectedness between the different content elements
	bind the content to the web device


Rather than design from the edges in, we need to design layout systems from the content out. To this end, Boulton asserts that grid system design should begin with a constraint, and he suggests we use the size of a fixed content element, such as an advertising unit or image, as a starting point for online grid calculations. Khoi Vinh advocates the same approach in his book, Ordering Disorder: Grid Principles for Web Design.

Boulton’s second and third tenets, however, are more complex and overlap significantly with each other. Connecting the different parts of the content and binding the content to the device share many characteristics and solutions:


	adopting ems and percentages as units of size for layout elements
	altering text size, line length and line height for different viewport dimensions
	providing higher resolution images for devices with greater pixel densities
	fluid layout grids, flexible images and responsive design


All can help relate the presentation of the content to its delivery in a certain context.

But how do we determine the relationship between one element of a layout and another? How can we avoid making arbitrary decisions about the relative sizes of parts of our designs? What can we use to connect the parts of our design to one another, and how can we bind the presentation of the content to the user’s device?

Tim Brown’s application of modular typographic scales hints at an answer. In the very useful tool he created for calculating such scales, Brown includes two musical ratios: the perfect fifth (2:3); and the perfect fourth (3:4). Why? Where do they come from? And what do they mean?

Harmonies musical and visual

Fundamental to music are rhythm and harmony.

As any drummer will tell you, without rhythm there is no music. Even when there’s no regular beat, any tune follows a rhythm, however irregular, simply because a change of note is a point of change in the music. Although rhythm, timing and pacing are all relevant to interaction design, right now it’s harmony we’re interested in.

Sometimes harmony is called the vertical aspect of music, and melody the horizontal. But this conceit overlooks the fact that harmony is both vertical and horizontal. A single melodic line, as it is played, implies various sets of harmonies on which it is grounded, whether or not those harmonies are played. So, harmony doesn’t just sit vertically beneath the horizontal melody, but moves horizontally as well, through harmonic progression.

To stretch this arrangement pixel-thin, we could argue that in onscreen design melody is the content, and the layout and arrangement of the content is the harmony. We sometimes say a design is harmonious when the interplay of different elements of a design is pleasing or balanced or in proportion, and the content (the melody) is set off or conveyed well by or appropriate to the design.

We seem to know instinctively whether a layout is harmonious…

In the design of The Great Discontent, the relationships between different elements combine to form a balanced whole.

…or not.

There’s no harmony in the Department for Education’s website because the different parts of the content don’t feel related to one another.

What is it that makes one design harmonious and another dissonant? It’s not just whether things line up, though that’s a start. I believe there are much deeper aesthetic forces at work, forces we can tap into in our onscreen designs. Now, I’m not going start a difficult discussion about aesthetics. For our purposes, we just need to know that it’s the branch of philosophy dealing with the nature of beauty, and the creation and perception of beauty. And among the key components in the perception of beauty are harmony and proportion. These have been part of traditional western aesthetics since Plato (about 2,500 years).

One of the ways we appreciate the beauty of music is through the harmonic intervals we hear. A musical interval is a combination of two notes and it describes the distance between the two pitches. For example, the distance between C and the G above it (if we take C as the tonic or root) is called a perfect fifth.

Left: C to G, a perfect fifth. Right: C and G, not a perfect fifth.

 

And, to get superficially scientific for a moment, each musical interval can be expressed as a ratio of the wavelength frequencies of the notes; for our perfect fifth, with every two wavelengths of C, there are three of G. And what is a ratio, if not a proportion of one thing to another?

So, simple musical harmony (using what’s known as just intonation1) affords us a set of proportions, expressed as ratios. Where better to apply these ideas of harmony and proportion from music in web design, than grid systems?

A digression: whither φ?

Quite often in our discussions of pure design and aesthetics, we mention the golden ratio and regurgitate the same justifications for its use: roots in antiquity; embodied in classical and Renaissance architecture and art; occurrence in nature; the New Twitter, and so forth (oh, really?).

Yet the ratios of musical intervals from just intonation are equally venerable and much more widespread: described by Pythagorus; employed in Palladian architecture, and printing, books and art from the Renaissance onwards; in modern times, film and television dimensions; standard international paper sizes (ISO 216, the A and B series); and, again and again, screen dimensions – chances are that screen you’re probably looking at right now has the proportions 2:3 (iPhone and iPod Touch), 3:4 (iPad and Kindle), 3:5 (many smartphones), 5:8 or 16:9 (many widescreen monitors), all ratios of musical intervals.

Back to our theme…

Musical interval ratios

Let’s take a look at most of the ratios within a couple of octaves and crunch some numbers to generate some percentages and other values that we can use in our designs. First, the intervals and their ratios in just intonation and expressed as ratios of one:

As you can see, the simple musical intervals are expressed as ratios of small whole numbers (integers). We can then normalize them as ratios of one, as well as derive percentage values, both in terms of the smaller value to the larger, and vice versa. These are the numbers we can incorporate into our designs. If you’ve ever written something like body { font: 100%/1.5 ""Museo Sans"", Helvetica, sans-serif; } in your CSS, you’re already using a musical ratio: the perfect fifth.

Modular scales allow us to generate a set of numbers based on a musical interval that can be used for all kinds of typographic and layout decisions to create harmony in a visual design for the web. As Tim Brown said at the 2010 Build conference:


	I think that from that most atomic unit – type – whole experiences can resonate, whole experiences can be harmonious. And whole experiences can have a purpose suited to our design intentions.


Once more, with feeling: connectedness

As well as modular scales, there are other methods of incorporating musical interval ratios into our work. Setting the ratio of font size to line height in CSS is one such example. We could also create a typographic hierarchy using the same principle and combining several ratios that we know harmonize well musically in a chord:

body { font-size: 75%; } /* =12px = base size or tonic */

h1 { font-size: 32px; font-size: 2.667rem; }
   /* =32px = 3:8 = major eleventh (C→F↑) */

h2 { font-size: 24px; font-size: 2rem; }
   /* =24px = 1:2 = octave (C→C↑) */

h3 { font-size: 20px; font-size: 1.667rem; }
   /* =20px = 3:5 = major sixth (C→A) */

figcaption, small { font-size: 9px; font-size : 0.75rem }
   /* =9px = 3:4 = perfect fourth (C→F) */

Whoa! Hold your reindeer, Santa! How can we know what interval combinations work well together to form chords? Well, I’m a classically trained musician, so perhaps I have an advantage. To avoid a long, technically complex digression into musical harmony, here are a few basic combinations of intervals that are harmonious in one way or another:


	unison; major third; perfect fifth; octave
	unison; perfect fourth; major sixth; octave
	unison; minor third; minor sixth; octave
	unison; minor third; diminished fifth; major sixth; octave


This isn’t to say that other combinations can’t be used to interesting effect and particular purpose – they surely can – but I have to make sure there’s something left for you to experiment with in the wee small hours over the holiday. Bear in mind, though, were I to play you two notes from the same scale to form a minor second, for example, you’d probably say it was dissonant and maybe that quality of the 15:16 ratio would be translated to the design.

 

In the typographic hierarchy above, you’ll notice I used an interval in the higher octave, which affords a broader range of ratios while retaining the harmony. Thus, a perfect fifth (2:3) becomes a major twelfth (1:3), or a major sixth (3:5) becomes a major thirteenth (3:10).

The harmonic ratios can obviously be used as proportions for layout as well, in several different ways:


	image width and height (for example, 450×800px = 9:16 = minor seventh)
	main content to page width (67%:100% = 2:3 = perfect fifth)
	page width to viewport width (80%:100% = 4:5 = major third)


One great benefit of using such ratios in web design work is that they can be applied in responsive web design. Proportional values, based on percentages or equivalent em units, will scale with changing viewports, so your layout and image proportions can be maintained or deliberately changed, as we’re about to find out, across devices.

Small speakers, tall speakers: binding to the device

The musical interval ratios also provide an opportunity, not only to create connectedness between the parts of a layout, but to bind the content to a device – that elusive antiphonal geometry. Just as a textblock and page resonate together, so too can web content and the screen. Earlier, I mentioned that several common screen aspect ratios match musical interval ratios. It would seem, then, that we have a set of proportions that we can use in different ways to establish and retain a sense of harmony that can be based on and change with those contexts. Using musical interval ratios, we can bind the display of our content to the device it’s displayed on.

If you haven’t met already, let me introduce you to the device-aspect-ratio property of CSS media queries.

@media only screen and (device-aspect-ratio: 3/4) { }
@media only screen and (device-aspect-ratio: 480/640) { }
@media only screen and (device-aspect-ratio: 600/800) { }
@media only screen and (device-aspect-ratio: 768/1024) { }

Regardless of the precise pixel values, each of these media queries would apply to devices whose display area has an aspect ratio of 3:4. It works by comparing the device-width with the device-height. (It’s not to be confused with aspect-ratio, which is defined by the width and height of the browser within the device.) The values in the media query are always presented as width/height, with portrait being the default orientation for smartphones and tablets; that is, to match an iPhone screen, you’d use device-aspect-ratio: 2/3, not 3/2, which won’t work.

Here’s a table of the musical intervals with their corresponding screens.

[You might argue that I’m playing fast and loose with the ratios. I suppose, mathematically speaking, 9:16 is not the same as 16:9: I’m no expert. But let’s not throw the baby out with the bath water, particularly at Christmas.]

With this in mind, we can begin to write media queries that will influence various typographic and layout values in line with the aspect ratios of specific screens and in combination with em-based min-width queries that work from smaller, mobile screens to larger, desktop screens.

Here’s a very simple demo page with only some text, an image with a caption and a little basic layout: no seasonal overindulgence here.

Demo: Sample page using device-aspect-ratio media queries based on musical interval ratios

Our initial styles for all devices are based on the perfect fifth, with the major third and octave rounding things out into a harmonious whole, whether or not media queries are supported. For example:

html { font-size: 100%; line-height: 1.5; }
   /* font-size:line-height = 16:24 = 2:3 = perfect fifth */

h1 { font-size: 32px; font-size: 2rem; line-height: 1.25; }
   /* font-size:line-height = 32:40 = 4:5 = major third
      body:h1 = 16:32 = 1:2 = octave */

While we should really consider methods of delivering images appropriate to the screen size, let’s just stick to a single image for all devices. But why don’t we change its aspect ratio from 4:3 to 3:2, to fit with our harmonic scheme? It’s easy enough to do with overflow:hidden on the <figure> element to hide a part of the image, and a negative margin fudge:

figure img { margin: -8.5% 0 0 0; width: 100%; max-width: 100%; }

Our first break point targets devices 320 pixels wide with an aspect ratio of 2:3, namely the iPhone and iPod Touch:

/* 320px = 20×16 */
@media only screen and (min-width: 20em) and (device-aspect-ratio: 2/3) { }

We’re actually already there, of course, as the intervals we’ve chosen resonate with this aspect ratio – the content is already bound to the device.

Our next media query, then, will make some changes to match a different ratio, the major sixth (3:5), which is same as that of many smartphones:

/* 480px = 30×16 */
@media only screen and (min-width: 30em) and (device-aspect-ratio: 3/5) { }

A different aspect ratio might require a change in harmony. For devices with these proportions, we’ll now use the perfect fourth (3:4) and the major sixth (3:5) along with the octave we already have to create a new resonating harmony. For instance, a slightly wider screen means we can increase the  line-height to aid the legibility of longer lines:

html { line-height: 1.667; }
   /* font-size:line-height = 16:26.672 = 3:5 = major sixth */

h1 { font-size: 32px; font-size: 2rem; line-height: 1.667; }
   /* font-size:line-height = 32:53.333 = 3:5 = major sixth
      body:h1 = 16:32 = 1:2 = octave */

and we can remove the negative margin to display our 4:3 image in its entirety.

Each screen displays content styled using relationships related to its own proportions. On the left, an iPhone 4 (2:3); on the right, a Samsung Nexus S (3:5). Your mileage may vary.

Another device, another media query. At 768 pixels, screens are wide enough to add columns. The ratios we’ve used for the 3:5 screens include the perfect fourth (3:4) so we don’t need to change any of the font measurements, but we can base the proportions of the columns on the major sixth interval:

article { float: left; width: 56%; }
   /* width of main column 3:5 (60% of 100%, major sixth)
      incorporating gutter width */

aside { float : right; width : 36%; }

On devices with a 3:4 aspect ratio, this works even better in landscape orientation.

While not every screen over 768 pixels wide will have 3:4 proportions, the range of intervals informing the design ensure harmonious relationships between the different parts of the layout.

For wide screens proper (break point at 1,280 pixels) we can employ a new set of harmonious intervals. Many laptop and desktop screens have a 16:10 aspect ratio, which boils down to 8:5, equivalent to the minor sixth (5:8). Combined with a minor third (5:6) and the octave (1:2), this creates a new harmony appropriate to these devices. Let’s increase the font size and change the image’s aspect ratio to match:

html { font-size: 120%; line-height: 1.6; }
   /* font-size increased for wider screens from 16px to 19.2px
      (5:6 = minor third)
      font-size:line-height = 19.2:30.72 = 5:8 = minor sixth */

figure img { margin: -12.5% 0 0 ; }	
   /* using -ve margin combined with overflow:hidden
      on the figure element
      to crop the image from 4:3 to 8:5 = minor sixth */

A wide screen with a 8:5 (16:10) aspect ratio and an image to match.

With more pixels at our disposal, we can also now use the musical interval ratios to determine the width of the layout, and change the column proportions as well:

section { margin: 0 auto; width: 83.333%; }
   /* content width:screen width = 5:6 = minor third */

article { width: 60%; }
   /* width of main column 5:8 (62.5% of 100%, minor sixth)
      incorporating gutter width */

aside { width: 35%; }

With some carefully targeted media queries, we can begin to reach towards fulfilling the second and third tenets of Boulton’s new canon for web design: connecting the parts of content through relationships embodied in the layout design; and binding the content to the devices people use to access it.

Coda

Musical interval ratios and screen aspect ratios reveal more than convenient correspondence. These proportions work on a deep aesthetic level. Much is claimed for the golden ratio φ, but none of the screens pervading our lives use it. Perhaps that’s an accident of technology, but can making screens to φ’s proportions be more difficult or expensive than 2:3 or 3:4 or 16:10? Here, then, is not just one but a set of proportions with a uniquely human focus, originating in nature, recognized in antiquity, fundamental still.

We find music to be an art steeped with meaning, yet, unlike literary and representational arts, purely instrumental music has no obvious semantic content. It boasts an ability to express emotions while remaining an abstract art in some sense, which makes it very like design. These days, we’re rightly encouraged to design for emotion, to make our users’ experience meaningful, seductive, delightful. Using musical ideas and principles in our designs can help achieve those ends.

Let’s not be naïve, of course; designing web pages is even less like composing music than it’s like designing for print. In visual design, the eye will always be sovereign to the ear; following these principles will only get us so far. We cannot truly claim that a carefully composed web page layout will have the same qualities and effect as any musical patterns that inform it. In music, a set of intervals is always harmonious in relation to other sets of intervals: music rarely stands still. What aspect ratios will future screens take? Already today there is great variation in devices and support for media queries (and within that, support for device-aspect-ratio). And what of non-western musical traditions? Or rhythm, form, tempo and dynamics? What I’ve demonstrated above is only a suggestion, a tentative exploration of one possible way forward.

But as our discipline matures and we become more articulate about what we do, we must look longer and deeper into areas of human endeavour already rich with value. Music is a fertile ground to explore and has the potential to yield up new approaches for web design.

266,Collaborative Development for a Responsively Designed Web,"In responsive web design we’ve found a technique that allows us to design for the web as a medium in its own right: one that presents a fluid, adaptable and ever changing canvas.

Until this point, we gave little thought to the environment in which users will experience our work, caring more about the aggregate than the individual. The applications we use encourage rigid layouts, whilst linear processes focus on clients signing off paintings of websites that have little regard for behaviour and interactions. The handover of pristine, pixel-perfect creations to developers isn’t dissimilar to farting before exiting a crowded lift, leaving front-end developers scratching their heads as they fill in the inevitable gaps. If you haven’t already, I recommend reading Drew’s checklist of things to consider before handing over a design.

Somehow, this broken methodology has survived for the last fifteen years or so. Even the advent of web standards has had little impact. Now, as we face an onslaught of different devices, the true universality of the web can no longer be ignored.

Responsive web design is just the thin end of the wedge. Largely concerned with layout, its underlying philosophy could ignite a trend towards interfaces that adapt to any number of different variables: input methods, bandwidth availability, user preference – you name it!

With such adaptability, a collaborative and iterative process is required. Ethan Marcotte, who worked with the team behind the responsive redesign of the Boston Globe website, talked about such an approach in his book:


	The responsive projects I’ve worked on have had a lot of success combining design and development into one hybrid phase, bringing the two teams into one highly collaborative group.


Whilst their process still involved the creation of desktop-centric mock-ups, these were presented to the entire team early on, where questions about how pages might adapt and behave at different sizes were asked. Mock-ups were quickly converted into HTML prototypes, meaning further decisions could be based on usage rather than guesswork (and endless hours spent in Photoshop).

Regardless of the exact process, it’s clear that the relationship between our two disciplines is more crucial than ever. Yet, historically, it seems a wedge has been driven between us – perhaps a result of segregation and waterfall-style processes – resulting in animosity.

So how can we improve this relationship? Ultimately, we’ll need to adapt, but even within existing workflows we can start to overlap. Simply adjusting our attitude can effect change, and bring design and development teams closer together.


	Good design is constant contact.

	Mark Otto


The way we work needs to be more open and inclusive. For example, ensuring members of the development team attend initial kick-off meetings and design workshops will not only ensure technical concerns are raised, but mean that those implementing our designs better understand the problems we’re trying to solve.

It can also be useful at this stage to explain how you work and the sort of deliverables you expect to produce. This will give developers a chance to make recommendations on how these can be optimized for their own needs.

You may even find opportunities to share the load. On a recent project I worked on, our development partners offered to produce the interactive prototypes needed for user testing. This allowed us to concentrate on refining the experience, whilst they were able to get a head start on building the product.

While developers should be involved at the beginning of projects, it’s also important that designers are able to review and contribute to a product as it’s being built. Any handover should be done in person, and ideally you’ll have a day set aside to do so. Having additional budget available for follow-up design reviews is also recommended. Learning how to use version control tools like Subversion or Git will allow you to work within the same environment as developers, and allow you to contribute code or graphic assets directly to a project if needed.

Don’t underestimate the benefits of designer and developer sitting next to each other. Subtle nuances can be explored far more easily than if they were conducted over email or phone. As Ethan writes, “‘Design’ is the means, not merely the end; the path we walk over the course of a project, the choices we make”.

It’s from collaboration like this that I’ve become fond of producing visual style guides. These demonstrate typographic treatments for common markup and patterns (blockquotes, lists, pagination, basic form controls and so on). Thinking in terms of components rather than individual pages not only fits in better with how a developer will implement a site, but can also ensure your design works as a coherent whole.

Despite the amount of research and design produced, when it comes to the crunch, there will always be a need for compromise. As the old saying goes, ‘fast, cheap and good – pick two.’ It’s important that you know which pieces are crucial to a design and which areas can allow for movement. Pick your battles wisely. Having an agreed set of design principles can be useful when making such decisions, as they help everyone focus on the goals of the project.


	The best compromises are reached when both sides understand the issues of the other.

	Richard Rutter


Ultimately, better collaboration comes through a shared understanding of the different competencies required to build a website. Instead of viewing ourselves in terms of discrete roles, we should instead look to emphasize our range of abilities, and work with others whose skills are complementary.

Perhaps somebody who actively seeks to broaden their knowledge is the mark of a professional. Seek these people out.

The best developers I’ve worked with have a respect for design, probably having attempted to do some themselves! Having wrangled with a few MySQL databases myself, I certainly believe the obverse is true. While knowing HTML won’t necessarily make you a better designer, it will help you understand the issues being faced by a front-end developer and, more importantly, allow you to offer solutions or alternative approaches.

So take a moment to think about how you work with developers and how you could improve your relationship with them. What are you doing to ease the path towards our collaborative future?",2011,Paul Lloyd,paulrobertlloyd,2011-12-05T00:00:00+00:00,https://24ways.org/2011/collaborative-development-for-a-responsively-designed-web/,business
274,Adaptive Images for Responsive Designs,"So you’ve been building some responsive designs and you’ve been working through your checklist of things to do:


	You started with the content and designed around it, with mobile in mind first.
	You’ve gone liquid and there’s nary a px value in sight; % is your weapon of choice now.
	You’ve baked in a few media queries to adapt your layout and tweak your design at different window widths.
	You’ve made your images scale to the container width using the fluid Image technique.
	You’ve even done the same for your videos using a nifty bit of JavaScript.


You’ve done a good job so pat yourself on the back. But there’s still a problem and it’s as tricky as it is important: image resolutions.

HTML has an <img> problem

CSS is great at adapting a website design to different window sizes – it allows you not only to tweak layout but also to send rescaled versions of the design’s images. And you want to do that because, after all, a smartphone does not need a 1,900-pixel background image1.

HTML is less great. In the same way that you don’t want CSS background images to be larger than required, you don’t want that happening with <img>s either. A smartphone only needs a small image but desktop users need a large one. Unfortunately <img>s can’t adapt like CSS, so what do we do?

Well, you could just use a high resolution image and the fluid image technique would scale it down to fit the viewport; but that’s sending an image five or six times the file size that’s really needed, which makes it slow to download and unpleasant to use. Smartphones are pretty impressive devices – my ancient iPhone 3G is more powerful in every way than my first proper computer – but they’re still terribly slow in comparison to today’s desktop machines. Sending a massive image means it has to be manipulated in memory and redrawn as you scroll. You’ll find phones rapidly run out of RAM and slow to a crawl.

Well, OK. You went mobile first with everything else so why not put in mobile resolution <img>s too? Because even though mobile devices are rapidly gaining share in your analytics stats, they’re still not likely to be the major share of your user base. I don’t think desktop users would be happy with pokey little mobile resolution images, do you? What we need are adaptive images.

Adaptive image techniques

There are a number of possible solutions, each with pros and cons, and it’s not as simple to find a graceful solution as you might expect.

Your first thought might be to use JavaScript to trawl through the markup and rewrite the source attribute. That’ll get you the right end result, but it’ll have done it in a way you absolutely don’t want. That’s because of the way browsers load resources. It starts to load the HTML and builds the page on-the-fly; as soon as it finds an <img> element it immediately asks the server for that image. After the HTML has finished loading, the JavaScript will run, change the src attribute, and then the browser will request that new image too. Not instead of, but as well as. Not good: that’s added more bloat instead of cutting it.

Plain JavaScript is out then, which is a problem, because what other tools do we have to work with as web designers? Let’s ignore that for now and I’ll outline another issue with the concept of serving different resolution images for different window widths: a basic file management problem. To request a different image, that image has to exist on the server. How’s it going to get there? That’s not a trivial problem, especially if you have non-technical users that update content through a CMS. Let’s say you solve that – do you plan on a simple binary switch: big image|little image? Is that really efficient or future-proof? What happens if you have an archive of existing content that needs to behave this way? Can you apply such a solution to existing content or markup?

There’s a detailed round-up of potential techniques for solving the adaptive images problem over at the Cloud Four blog if you fancy a dig around exploring all the options currently available. But I’m here to show you what I think is the most flexible and easy to implement solution, so here we are.

Adaptive Images

Adaptive Images aims to mitigate most of the issues surrounding the problems of bringing the venerable <img> tag into the 21st century. And it works by leaving that tag completely alone – just add that desktop resolution image into the markup as you’ve been doing for years now. We’ll fix it using secret magic techniques and bottled pixie dreams. Well, fine: with one .htaccess file, one small PHP file and one line of JavaScript. But you’re killing the mystique with that kind of talk.

So, what does this solution do?


	It allows <img>s to adapt to the same break points you use in your media queries, giving granular control in the same way you get with your CSS.
	It installs on your server in five minutes or less and after that is automatic and you don’t need to do anything.
	It generates its own rescaled images on the server and doesn’t require markup changes, so you can apply it to existing web content.
	If you wish, it will make all of your images go mobile-first (just in case that’s what you want if JavaScript and cookies aren’t available).


Sound good? I hope so. Here’s what you do.

Setting up and rolling out

I’ll assume you have some basic server knowledge along with that wealth of front-end wisdom exploding out of your head: that you know not to overwrite any existing .htaccess file for example, and how to set file permissions on your server. Feeling up to it? Excellent.


	Download the latest version of Adaptive Images either from the website or from the GitHub repository.
	Upload the included .htaccess and adaptive-images.php files into the root folder of your website.
	Create a directory called ai-cache and make sure the server can write to it (CHMOD 755 should do it).
	Add the following line of JavaScript into the <head> of your site:


<script>document.cookie='resolution='+Math.max(screen.width,screen.height)+'; path=/‘;</script>

That’s it, unless you want to tweak the default settings. You likely do, but essentially you’re already up and running.

How it works

Adaptive Images does a number of things depending on the scenario the script has to handle, but here’s a basic overview of what it does when you load a page running it:


	A session cookie is written with the value of the visitor’s screen size in pixels.
	The HTML encounters an <img> tag and sends a request to the server for that image. It also sends the cookie, because that’s how browsers work.
	Apache sits on the server and receives the request for the image. Apache then has a look in the .htaccess file to see if there are any special instructions for files in the requested URL.
	There are! The .htaccess says “Hey, server! Any request you get for a JPG, GIF or PNG file just send to the adaptive-images.php file instead.”
	The PHP file then does some intelligent thinking which can cover a number of scenarios, but I’ll illustrate one path that can happen:


	
		The PHP file looks for the cookie and finds out that the user has a maximum screen width of 480px.
		The PHP has a look at the available media query sizes that were configured and decides which one matches the user’s device.
		It then has a look inside the /ai-cache/480/ folder to see if a rescaled image already exists there.
		We’ll pretend it doesn’t – the PHP then goes to the actual requested URI and finds that the original file does exist.
		It has a look to see how wide that image is. If it’s already smaller than the user’s screen width it sends it along and stops there. But, let’s pretend the image is 1,000px wide.
		The PHP then resizes the image and saves it into the /ai-cache/480 folder ready for the next time someone needs it.
	

It also does a few other things when needs arise, for example:


	It sends images with a cache header field that tells proxies not to cache the image, while telling browsers they should. This avoids problems with proxy servers and network caching systems grabbing the wrong image and storing it.
	It handles cases where there isn’t a cookie set, and you can choose whether to then send the mobile version or the largest configured media query size.
	It compares timestamps between the source image and the generated cache image – to ensure that if the source image gets updated, the old cached file won’t be sent.


Customizing

There are a few options you can customize if you don’t like the default values. By looking in the PHP’s configuration section at the top of the file, you can:


	Set the resolution breakpoints to match your media query break points.
	Change the name and location of the ai-cache folder.
	Change the quality level any generated JPG images are saved at.
	Have it perform a subtle sharpen on rescaled images to help keep detail.
	Toggle whether you want it to compare the files in the cache folder with the source ones or not.
	Set how long the browser should cache the images for.
	Switch between a mobile-first or desktop-first approach when a cookie isn’t found.


More importantly, you probably want to omit a few folders from the AI behaviour. You don’t need or want it resizing the images you’re using in your CSS, for example. That’s fine – just open up the .htaccess file and follow the instructions to list any directories you want AI to ignore. Or, if you’re a dab hand at RewriteRules you can remove the exclamation mark at the start of the rule and it’ll only apply AI behaviour to a given list of folders.

Caveats

As I mentioned, I think this is one of the most flexible, future-proof, retrofittable and easy to use solutions available today. But, there are problems with this approach as there are with all of the ones I’ve seen so far.

This is a PHP solution

I wish I was smarter and knew some fancy modern languages the cool kids discuss at parties, but I don’t. So, you need PHP on your server. That said, Adaptive Images has a Creative Commons licence2 and I would welcome anyone to contribute a port of the code3. 

Content delivery networks

Adaptive Images relies on the server being able to: intercept requests for images; do some logic; and send one of a given number of responses. Content delivery networks are generally dumb caches, and they won’t allow that to happen. Adaptive Images will not work if you’re using a CDN to deliver your website.

A minor but interesting cookie issue.

As Yoav Weiss pointed out in his article Preloaders, cookies and race conditions, there is no way to guarantee that a cookie will be set before images are requested – even though the JavaScript that sets the cookie is loaded by the browser before it finds any <img> tags. That could mean images being requested without a cookie being available. Adaptive Images has a two-fold mechanism to avoid this being a problem:


	The $mobile_first toggle allows you to choose what to send to a browser if a cookie isn’t set. If FALSE then it will send the highest configured resolution; if TRUE it will send the lowest.
	Even if set to TRUE, Adaptive Images checks the User Agent String. If it discovers the user is on a desktop environment, it will override $mobile_first and set it to FALSE.


This means that if $mobile_first is set to TRUE and the user was unlucky (their browser didn’t write the cookie fast enough), mobile devices will be supplied with the smallest image, and desktop devices will get the largest.

The best way to get a cookie written is to use JavaScript as I’ve explained above, because it’s the fastest way. However, for those that want it, there is a JavaScript-free method which uses CSS and a bogus PHP ‘image’ to set the cookie. A word of caution: because it requests an external file, this method is slower than the JavaScript one, and it is very likely that the cookie won’t be set until after images have been requested.

The future

For today, this is a pretty good solution. It works, and as it doesn’t interfere with your markup or source material in any way, the process is non-destructive. If a future solution is superior, you can just remove the Adaptive Images files and you’re good to go – you’d never know AI had been there.

However, this isn’t really a long-term solution, not least because of the intermittent problem of the cookie and image request race condition. What we really need are a number of standardized ways to handle this in the future.

First, we could do with browsers sending far more information about the user’s environment along with each HTTP request (device size, connection speed, pixel density, etc.), because the way things work now is no longer fit for purpose. The web now is a much broader entity used on far more diverse devices than when these technologies were dreamed up, and we absolutely require the server to have better knowledge about device capabilities than is currently possible. Relying on cookies to do this job doesn’t cut it, and the User Agent String is a complete mess incapable of fulfilling the various purposes we are forced to hijack it for.

Secondly, we need a W3C-backed markup level solution to supply semantically different content at different resolutions, not just rescaled versions of the same content as Adaptive Images does.

I hope you’ve found this interesting and will find Adaptive Images useful.

269,Adaptive Images for Responsive Designs… Again,"When I was asked to write an article for 24 ways I jumped at the chance, as I’d been wanting to write about some fun hacks for responsive images and related parsing behaviours. My heart sank a little when Matt Wilcox beat me to the subject, but it floated back up when I realized I disagreed with his method and still had something to write about.

So, Matt Wilcox, if that is your real name (and I’m pretty sure it is), I disagree. I see your dirty server-based hack and raise you an even dirtier client-side hack. Evil laugh, etc., etc.

You guys can stomach yet another article about responsive design, right? Right?

Half the room gets up to leave

Whoa, whoa… OK, I’ll cut to the chase…

TL;DR

In a previous episode, we were introduced to Debbie and her responsive cat poetry page. Well, now she’s added some reviews of cat videos and some images of cats. Check out her new page and have a play around with the browser window. At smaller widths, the images change and the design responds. The benefits of this method are:


	it’s entirely client-side
	images are still shown to users without JavaScript
	your media queries stay in your CSS file
	no repetition of image URLs
	no extra downloads per image
	it’s fast enough to work on resize
	it’s pure filth


What’s wrong with the server-side solution?

Responsive design is a client-side issue; involving the server creates a boatload of problems.


	It sets a cookie at the top of the page which is read in subsequent requests. However, the cookie is not guaranteed to be set in time for requests on the same page, so the server may see an old value or no value at all.
	Serving images via server scripts is much slower than plain old static hosting.
	The URL can only cache with vary: cookie, so the cache breaks when the cookie changes, even if the change is unrelated. Also, far-future caching is out for devices that can change width.
	It depends on detecting screen width, which is rather messy on mobile devices.
	Responding to things other than screen width (such as DPI) means packing more information into the cookie, and a more complicated script at the top of each page.


So, why isn’t this straightforward on the client?

Client-side solutions to the problem involve JavaScript testing user agent properties (such as screen width), looping through some images and setting their URLs accordingly. However, by the time JavaScript has sprung into action, the original image source has already started downloading. If you change the source of an image via JavaScript, you’re setting off yet another request.

Images are downloaded as soon as their DOM node is created. They don’t need to be visible, they don’t need to be in the document.

new Image().src = url

The above will start an HTTP request for url. This is a handy trick for quick requests and preloading, but also shows the browser’s eagerness to download images.

Here’s an example of that in action. Check out the network tab in Web Inspector (other non-WebKit development aids are available) to see the image requests.

Because of this, some client-side solutions look like this:

<img src=""t.gif"" data-src=""real-image.jpg"" data-bigger-src=""real-bigger-image.jpg"">

where t.gif is a 1×1px tiny transparent GIF.

This results in no images if JavaScript isn’t available. Dealing with the absence of JavaScript is still important, even on mobile. I was recently asked to make a website work on an old Blackberry 9000. I was able to get most of the way there by preventing that OS parsing any JavaScript, and that was only possible because the site didn’t depend on it.

We need to delay loading images for JavaScript users, but ensure they load for users without JavaScript. How can we conditionally parse markup depending on JavaScript support?

Oh yeah! <noscript>!

<noscript>
    <img src=""image.jpg"">
</noscript>

Whoa! First spacer GIFs and now <noscript>? This really is the future! The image above will only load for users without JavaScript support. Now all we need to do is send JavaScript in there to get the textContent of the <noscript> element, then we can alter the image source before handing it to the DOM for parsing.

Here’s an example of that working … unless you’re using Internet Explorer.

Internet Explorer doesn’t retain the content of <noscript> elements. As soon as it’s parsed, it considers it an empty element. FANKS INTERNET EXPLORER. This is why some solutions do this:

<noscript data-src=""image.jpg"">
    <img src=""image.jpg"">
</noscript>

so JavaScript can still get at the URL via the data-src attribute. However, repeating stuff isn’t great. Surely we can do better than that.

A dirty, dirty hack

Thankfully, I managed to come up with a solution, and by me, I mean someone cleverer than me. Pornel’s solution uses <noscript>, but surely we don’t need that.

Now, before we look at this, I can’t stress how dirty it is. It’s so dirty that if you’ve seen it, schools will refuse to employ you.

<script>document.write('<' + '!--')</script>
<img src=""image.jpg"">
<!---->

Phwoar! Dirty, isn’t it? I’ll stop for a moment, so you can go have a wash.

Done? Excellent.

With this, the image is wrapped in a comment only for users with JavaScript. Without JavaScript, we get the image. Unlike the <noscript> example above, we can get the text content of the comment pretty easily.

Hurrah! But wait… Some browsers are sometimes downloading the image, even with JavaScript enabled. Notably Firefox. Huh?

Images are downloaded in comments now? What?

No. What we’re seeing here is the effect of speculative parsing. Here’s what’s happening:



While the browser is parsing the script, it parses the rest of the document. This is usually a good thing, as it can download subsequent images and scripts without waiting for the script to complete. The problem here is we create an unbalanced tree.

 An unbalanced tree, yesterday.

In this case, the browser must throw away its speculative parsing and reparse from the end of the <script> element, taking our document.write into consideration. Unfortunately, by this stage it may have already discovered the image and sent an HTTP request for it.

A dirty, dirty hack… that works

Pornel was right: we still need the <noscript> element to cater for browsers with speculative parsing.

<script>document.write('<' + '!--')</script><noscript>
    <img src=""image.jpg"">
</noscript -->

And there we have it. We can now prevent images loading for users with JavaScript, but we can still get at the markup.

We’re still creating an unbalanced tree and there’s a performance impact in that. However, the parser won’t have got far by the time our script executes, so the impact is small. Unbalanced trees are more of a concern for external scripts; a lot of parsing can happen by the time the script has downloaded and parsed.

Using dirtiness to create responsive images

Now all we need to do is give each of our dirty scripts a class name, then JavaScript can pick them up, grab the markup from the comment and decide what to do with the images.

This technique isn’t exclusively useful for responsive images. It could also be used to delay images loading until they’ve scrolled into view. But to do that you’ll need a bulletproof way of detecting when elements are in view. This involves getting the height of the viewport, which is extremely unreliable on mobile devices.

Here’s a hastily thrown together example showing how it can be used for responsive images.

I adjust the end of the image URLs conditionally depending on the result of media queries. This is done on page load, and on resize.

I’m using regular expressions to alter the URLs. Using regex to deal with HTML is usually a sign of insanity, but parsing it with the browser’s DOM parser would trigger the download of images before we change the URLs. My implementation currently requires double-quoted image URLs, because I’m lazy. Wanna fight about it?

Media querying via JavaScript

Jeremy Keith used document.documentElement.clientWidth in his example, which is great as a proof of concept, but unfortunately is rather unreliable across mobile devices.

Thankfully, standards are coming to the rescue with window.matchMedia, which lets us provide a media query string and get a boolean result. There’s even a great polyfill for browsers that don’t support it (as long as they support media queries in CSS).

I didn’t go with that for three reasons:


	I’d like to keep media queries in the CSS file, if possible.
	I wanted something a little lighter to keep things speedy while resizing.
	It’s just not dirty enough yet.


To make things ultra-dirty, I add a test element to the page with a specific class, let’s say media-test. Then, I control the width of it using media queries in my CSS file:

@media all and (min-width: 640px) {
    .media-test {
        width: 1px;
    }
}
@media all and (min-width: 926px) {
    .media-test {
        width: 2px;
    }
}

The JavaScript part changes the URL suffix depending on the width of media-test. I’m using a min-width media query, but you can use others such as pixel-ratio to detect high DPI displays. Basically, it’s a hacky way for CSS to set a value that can be picked up by JavaScript. It means the bit that signals changes to the images sits with the rest of the responsive code, without duplication.

Also, phwoar, dirty!

The API

I threw a script together to demonstrate the technique. I’m not particularly attached to it, I’m not even sure I like it, but here’s the API:

responsiveGallery({
    // Class name of dirty script element(s) to target
    scriptClass: 'dirty-gallery-script',
    // Class name for our test element
    testClass: 'dirty-gallery-test',
    // The initial suffix of URLs, the bit that changes.
    initialSuffix: '-mobile.jpg',
    // A map of suffixes, for each width of 'dirty-gallery-test'
    suffixes: {
        '1': '-desktop.jpg',
        '2': '-large-desktop.jpg',
        '3': '-mobile-retina.jpg'
    }
});

The API can cover individual images or multiple galleries at once. In the example I gave at the start of the article I make two calls to the API, one for both galleries, and one for the single image above the video reviews. They’re separate calls because they respond slightly differently.

The future

Hopefully, we’ll get a proper solution to this soon. My favourite suggestion is the <picture> element that Bruce Lawson covers.

<picture alt=""Angry pirate"">
    <source src=""hires.png"" media=""min-width:800px"">
    <source src=""midres.png"" media=""min-width:480px"">
    <source src=""lores.png"">
    <!-- fallback for browsers without support -->
    <img src=""midres.png"" alt=""Angry pirate"">
</picture>

Unfortunately, we’re nowhere near that yet, and I’d still rather have my media queries stay in CSS. Perhaps the source elements could be skipped if they’re display:none; then they could have class names and be controlled via CSS. Sigh.

Well, I’m tired of writing now and I’m sure you’re tired of reading. I realize what I’ve presented is a yet another dirty hack to the responsive image problem (perhaps the dirtiest?) and may be completely unfeasible in professional situations. But isn’t that the true spirit of Christmas?

No.",2011,Jake Archibald,jakearchibald,2011-12-08T00:00:00+00:00,https://24ways.org/2011/adaptive-images-for-responsive-designs-again/,ux
239,Using the WebFont Loader to Make Browsers Behave the Same,"Web fonts give us designers a whole new typographic palette with which to work. However, browsers handle the loading of web fonts in different ways, and this can lead to inconsistent user experiences.

Safari, Chrome and Internet Explorer leave a blank space in place of the styled text while the web font is loading. Opera and Firefox show text with the default font which switches over when the web font has loaded, resulting in the so-called Flash of Unstyled Text (aka FOUT). Some people prefer Safari’s approach as it eliminates FOUT, others think the Firefox way is more appropriate as content can be read whilst fonts download. Whatever your preference, the WebFont Loader can make all browsers behave the same way.

The WebFont Loader is a JavaScript library that gives you extra control over font loading. It was co-developed by Google and Typekit, and released as open source. The WebFont Loader works with most web font services as well as with self-hosted fonts.

The WebFont Loader tells you when the following events happen as a browser downloads web fonts (or loads them from cache):


	when fonts start to download (‘loading’)
	when fonts finish loading (‘active’)
	if fonts fail to load (‘inactive’)


If your web page requires more than one font, the WebFont Loader will trigger events for individual fonts, and for all the fonts as a whole. This means you can find out when any single font has loaded, and when all the fonts have loaded (or failed to do so).

The WebFont Loader notifies you of these events in two ways: by applying special CSS classes when each event happens; and by firing JavaScript events. For our purposes, we’ll be using just the CSS classes.

Implementing the WebFont Loader

As stated above, the WebFont Loader works with most web font services as well as with self-hosted fonts.

Self-hosted fonts

To use the WebFont Loader when you are hosting the font files on your own server, paste the following code into your web page:

<script type=""text/javascript"">
WebFontConfig = {
	custom: { families: ['Font Family Name', 'Another Font Family'],
	urls: [ 'http://yourwebsite.com/styles.css' ] }
};
(function() {
	var wf = document.createElement('script');
	wf.src = ('https:' == document.location.protocol ? 'https' : 'http') + '://ajax.googleapis.com/ajax/libs/webfont/1/webfont.js';
	wf.type = 'text/javascript';
	wf.async = 'true';
	var s = document.getElementsByTagName('script')[0];
	s.parentNode.insertBefore(wf, s);
})();
</script>

Replace Font Family Name and Another Font Family with a comma-separated list of the font families you want to check against, and replace http://yourwebsite.com/styles.css with the URL of the style sheet where your @font-face rules reside.

Fontdeck

Assuming you have added some fonts to a website project in Fontdeck, use the afore-mentioned code for self-hosted solutions and replace http://yourwebsite.com/styles.css with the URL of the <link> tag in your Fontdeck website settings page. It will look something like http://f.fontdeck.com/s/css/xxxx/domain/nnnn.css.

Typekit

Typekit’s JavaScript-based implementation incorporates the WebFont Loader events by default, so you won’t need to include any WebFont Loader code.

Making all browsers behave like Safari

To make Firefox and Opera work in the same way as WebKit browsers (Safari, Chrome, etc.) and Internet Explorer, and thus minimise FOUT, you need to hide the text while the fonts are loading.

While fonts are loading, the WebFont Loader adds a class of wf-loading to the <html> element. Once the fonts have loaded, the wf-loading class is removed and replaced with a class of wf-active (or wf-inactive if all of the fonts failed to load). This means you can style elements on the page while the fonts are loading and then style them differently when the fonts have finished loading.

So, let’s say the text you need to hide while fonts are loading is contained in all paragraphs and top-level headings. By writing the following style rule into your CSS, you can hide the text while the fonts are loading:

.wf-loading h1, .wf-loading p {
	visibility:hidden;
}

Because the wf-loading class is removed once the the fonts have loaded, the visibility:hidden rule will stop being applied, and the text revealed. You can see this in action on this simple example page.

That works nicely across the board, but the situation is slightly more complicated. WebKit doesn’t wait for all fonts to load before displaying text: it displays text elements as soon as the relevant font is loaded. 

To emulate WebKit more accurately, we need to know when individual fonts have loaded, and apply styles accordingly. Fortunately, as mentioned earlier, the WebFont Loader has events for individual fonts too.

When a specific font is loading, a class of the form wf-fontfamilyname-n4-loading is applied. Assuming headings and paragraphs are styled in different fonts, we can make our CSS more specific as follows:

.wf-fontfamilyname-n4-loading h1, 
.wf-anotherfontfamily-n4-loading p {
	visibility:hidden;
}

Note that the font family name is transformed to lower case, with all spaces removed. The n4 is a shorthand for the weight and style of the font family. In most circumstances you’ll use n4 but refer to the WebFont Loader documentation for exceptions.

You can see it in action on this Safari example page (you’ll probably need to disable your cache to see any change occur).

Making all browsers behave like Firefox

To make WebKit browsers and Internet Explorer work like Firefox and Opera, you need to explicitly show text while the fonts are loading. In order to make this happen, you need to specify a font family which is not a web font while the fonts load, like this:

.wf-fontfamilyname-n4-loading h1 { 
    font-family: 'arial narrow', sans-serif; 
}
.wf-anotherfontfamily-n4-loading p { 
    font-family: arial, sans-serif; 
}

You can see this in action on the Firefox example page (again you’ll probably need to disable your cache to see any change occur).

And there’s more

That’s just the start of what can be done with the WebFont Loader. More areas to explore would be tweaking font sizes to reduce the impact of reflowing text and to better cater for very narrow fonts. By using the JavaScript events much more can be achieved too, such as fading in text as the fonts load.",2010,Richard Rutter,richardrutter,2010-12-02T00:00:00+00:00,https://24ways.org/2010/using-the-webfont-loader-to-make-browsers-behave-the-same/,code
221,"“Probably, Maybe, No”: The State of HTML5 Audio","With the hype around HTML5 and CSS3 exceeding levels not seen since 2005’s Ajax era, it’s worth noting that the excitement comes with good reason: the two specifications render many years of feature hacks redundant by replacing them with native features. For fun, consider how many CSS2-based rounded corners hacks you’ve probably glossed over, looking for a magic solution. These days, with CSS3, the magic is border-radius (and perhaps some vendor prefixes) followed by a coffee break.

CSS3’s border-radius, box-shadow, text-shadow and gradients, and HTML5’s <canvas>, <audio> and <video> are some of the most anticipated features we’ll see put to creative (ab)use as adoption of the ‘new shiny’ grows. Developers jumping on the cutting edge are using subsets of these features to little detriment, in most cases. The more popular CSS features are design flourishes that can degrade nicely, but the current audio and video implementations in particular suffer from a number of annoyances.

The new shiny: how we got here

Sound involves one of the five senses, a key part of daily life for most – and yet it has been strangely absent from HTML and much of the web by default. From a simplistic perspective, it seems odd that HTML did not include support for the full multimedia experience earlier, despite the CD-ROM-based craze of the early 1990s. In truth, standards like HTML can take much longer to bake, but eventually deliver the promise of a lowered barrier to entry, consistent implementations and shiny new features now possible ‘for free’ just about everywhere.

<img> was introduced early and naturally to HTML, despite having some opponents at the time. Perhaps <audio> and <video> were avoided, given the added technical complexity of decoding various multi-frame formats, plus the hardware and bandwidth limitations of the era. Perhaps there were quarrels about choosing a standard format or – more simply – maybe these elements just weren’t considered to be applicable to the HTML-based web at the time. In any event, browser plugins from programs like RealPlayer and QuickTime eventually helped to fill the in-page audio/video gap, handling <object> and <embed> markup which pointed to .wav, .avi, .rm or .mov files. Suffice it to say, the experience was inconsistent at best and, on the standards side of the fence right now, so is HTML5 in terms of audio and video.

: the theory

As far as HTML goes, the code for <audio> is simple and logical. Just as with <img>, a src attribute specifies the file to load. Pretty straightforward – sounds easy, right?

<audio src=""mysong.ogg"" controls>
	<!-- alternate content for unsupported case -->
	Download <a href=""mysong.ogg"">mysong.ogg</a>;
</audio>

Ah, if only it were that simple. The first problem is that the OGG audio format, while ‘free’, is not supported by some browsers. Conversely, nor is MP3, despite being a de facto standard used in all kinds of desktop software (and hardware). In fact, as of November 2010, no single audio format is commonly supported across all major HTML5-enabled browsers.

What you end up writing, then, is something like this:

<audio controls>
	<source src=""mysong.mp3"" />
	<source src=""mysong.ogg"" />
	<!-- alternate content for unsupported case, maybe Flash, etc. -->
	Download <a href=""mysong.ogg"">mysong.ogg</a> or <a href=""mysong.mp3"">mysong.mp3</a>
</audio>

Keep in mind, this is only a ‘first class’ experience for the HTML5 case; also, for non-supported browsers, you may want to look at another inline player (object/embed, or a JavaScript plus Flash API) to have inline audio. You can imagine the added code complexity in the case of supporting ‘first class’ experiences for older browsers, too.

: the caveats

With <img>, you typically don’t have to worry about format support – it just works – and that’s part of what makes a standard wonderful. JPEG, PNG, BMP, GIF, even TIFF images all render just fine if for no better reason, perhaps, than being implemented during the ‘wild west’ days of the web. The situation with <audio> today reflects a very different – read: business-aware – environment in 2010. (Further subtext: There’s a lot of [potential] money involved.) Regrettably, this is a collision of free and commercial interests, where the casualty is ultimately the user. Second up in the casualty list is you, the developer, who has to write additional code around this fragmented support.

The HTML5 audio API as implemented in JavaScript has one of the most un-computer-like responses I’ve ever seen, and inspired the title of this post. Calling new Audio().canPlayType('audio/mp3'), which queries the system for format support according to a MIME type, is supposed to return one of “probably”, “maybe”, or “no”. Sometimes, you’ll just get a null or empty string, which is also fun. A “maybe” response does not guarantee that a format will be supported; sometimes audio/mp3 gives “maybe,” but then audio/mpeg; codecs=""mp3"" will give a more-solid “probably” response. This can vary by browser or platform, too, depending on native support – and finally, the user may also be able to install codecs, extending support to include other formats. (Are you excited yet?)

Damn you, warring formats!

New market and business opportunities go hand-in-hand with technology developments. What we have here is certainly not failure to communicate; rather, we have competing parties shouting loudly in public in attempts to influence mindshare towards a de facto standard for audio and video. Unfortunately, the current situation means that at least two formats are effectively required to serve the majority of users correctly.

As it currently stands, we have the free and open source software camp of OGG Vorbis/WebM and its proponents (notably, Mozilla, Google and Opera in terms of browser makers), up against the non-free, proprietary and ‘closed’ camp of MP3 and MPEG4/HE-AAC/H.264 – which is where you’ll find commitments from Apple and Microsoft, among others. Apple is likely in with H.264 for the long haul, given its use of the format for its iTunes music store and video offerings.

It is generally held that H.264 is a technically superior format in terms of file size versus quality, but it involves intellectual property and, in many use cases, requires licensing fees. To be fair, there is a business model with H.264 and much has been invested in its development, but this approach is not often the kind that wins over the web. On that front, OGG/WebM may eventually win for being a ‘free’ format that does not involve a licensing scheme.

Closed software and tools ideologically clash with the open nature of the web, which exists largely thanks to free and open technology. Because of philosophical and business reasons, support for audio and video is fragmented across browsers adopting HTML5 features. It does not help that a large amount of audio and video currently exists in non-free MP3 and MPEG-4 formats. Adoption of <audio> and <video> may be slowed, since it is more complex than <img> and may feel ‘broken’ to developers when edge cases are encountered. Furthermore, the HTML5 spec does not mandate a single required format. The end result is that, as a developer, you must currently provide at least both MP3 and OGG, for example, to serve most existing HTML5-based user agents.

Transitioning to 



There will be some growing pains as developers start to pick up the new HTML5 shiny, while balancing the needs of current and older agents that don’t support either <audio> or the preferred format you may choose (for example, MP3). In either event, Flash or other plugins can be used as done traditionally within HTML4 documents to embed and play the relevant audio.



The SoundManager 2 page player demo in action.



Ideally, HTML5 audio should be used whenever possible with Flash as the backup option. A few JavaScript/Flash-based audio player projects exist which balance the two; in attempting to tackle this problem, I develop and maintain SoundManager 2, a JavaScript sound API which transparently uses HTML5 Audio() and, if needed, Flash for playing audio files. The internals can get somewhat ugly, but the transition between HTML4 and HTML5 is going to be just that – and even with HTML5, you will need some form of format fall-back in addition to graceful degradation.

It may be safest to fall back to MP3/MP4 formats for inline playback at this time, given wide support via Flash, some HTML5-based browsers and mobile devices. Considering the amount of MP3/MP4 media currently available, it is wiser to try these before falling through to a traditional file download process.

Early findings

Here is a brief list of behavioural notes, annoyances, bugs, quirks and general weirdness I have found while playing with HTML5-based audio at time of writing (November 2010):

Apple iPad/iPhone (iOS 4, iPad 3.2+)


	Only one sound can be played at a time. If a second sound starts, the first is stopped.
	No auto-play allowed. Sounds follow the pop-up window security model and can only be started from within a user event handler such as onclick/touch, and so on. Otherwise, playback attempts silently fail.
	Once started, a sequence of sounds can be created or played via the ‘finish’ event of the previous sound (for example, advancing through a playlist without interaction after first track starts).
	iPad, iOS 3.2: Occasional ‘infinite loop’ bug seen where audio does not complete and stop at a sound’s logical end – instead, it plays again from the beginning. Might be specific to example file format (HE-AAC) encoded from iTunes.

	Critical bug: Safari 4 and 5 intermittently fail to load or play HTML5 audio on Snow Leopard due to bug(s) in QuickTime X and/or other underlying frameworks. Known Apple ‘radar’ bug: bugs.webkit.org #32159 (see also, test case.) Amusing side note: Safari on Windows is fine.


Apple Safari, Windows


	Food for thought: if you download “Safari” alone on Windows, you will not get HTML5 audio/video support (tested in WinXP). You need to download “Safari + QuickTime” to get HTML5 audio/video support within Safari. (As far as I’m aware, Chrome, Firefox and Opera either include decoders or use system libraries accordingly. Presumably IE 9 will use OS-level APIs.)


General Quirks


	Seeking and loading, ‘progress’ events, and calculating bytes loaded versus bytes total should not be expected to be linear, as users can arbitrarily seek within a sound. It appears that some support for HTTP ranges exists, which adds a bit of logic to UI code. Browsers seem to vary slightly in their current implementations of these features.
	The onload event of a sound may be of little relevance, if non-linear loading is involved (see above note re: seeking).
	Interestingly (perhaps I missed it), the current spec does not seem to specify a panning or left/right channel mix option.
	The preload attribute values may vary slightly between browsers at this time.


Upcoming shiny: HTML5 Audio Data API




	With access to audio data, you can incorporate waveform and spectrum elements that make your designs react to music.



The HTML5 audio spec does a good job covering the basics of playback, but did not initially get into manipulation or generation of audio on-the-fly, something Flash has had for a number of years now. What if JavaScript could create, monitor and change audio dynamically, like a sort of audio <canvas> element? With that kind of capability, many dynamic audio processing features become feasible and, when combined with other media, can make for some impressive demos.

What started as a small idea among a small group of audio and programming enthusiasts grew to inspire a W3C audio incubator group, and continued to establish the Mozilla Audio Data API. Contributors wrote a patch for Firefox which was reviewed and revised, and is now slated to be in the public release of Firefox 4. Some background and demos are also detailed in an article from the BBC R&D blog.

There are plenty of live demos to see, which give an impression of the new creative ideas this API enables. Many concepts are not new in themselves, but it is exciting to see this sort of thing happening within the native browser context.

Mozilla is not alone in this effort; the WebKit folks are also working on a JavaScriptAudioNode interface, which implements similar audio buffering and sample elements.

The future?

It is my hope that we’ll see a common format emerge in terms of support across the major browsers for both audio and video; otherwise, support will continue to be fragmented and mildly frustrating to develop for, and that can impede growth of the feature. It’s a big call, but if <img> had lacked a common format back in the wild west era, I doubt the web would have grown to where it is today.

Complaints and nitpicks aside, HTML5 brings excellent progress on the browser multimedia front, and the first signs of native support are a welcome improvement given all audio and video previously relied on plugins. There is good reason to be excited. While there is room for more, support could certainly be much worse – and as tends to happen with specifications, the implementations targeting them should improve over time.

Note: Thanks to Nate Koechley, who suggested the Audio().canPlayType() response be part of the article title.",2010,Scott Schiller,scottschiller,2010-12-08T00:00:00+00:00,https://24ways.org/2010/the-state-of-html5-audio/,code
228,The Great Unveiling,"The moment of unveiling our designs should be among our proudest, but it never seems to work out that way. Instead of a chance to show how we can bring our clients’ visions to life, critique can be a tense, worrying ordeal. And yes, the stakes are high: a superb design is only superb if it goes live. Mismanage the feedback process and your research, creativity and hard work can be wasted, and your client may wonder whether you’ve been worth the investment.

The great unveiling is a pivotal part of the design process, but it needn’t be a negative one. Just as usability testing teaches us whether our designs meet user needs, presenting our work to clients tells us whether we’ve met important business goals. So how can we turn the tide to make presenting designs a constructive experience, and to give good designs a chance to shine through?

Timing is everything

First, consider when you should seek others’ opinions. Your personal style will influence whether you show early sketches or wait to demonstrate something more complete. Some designers thrive at low fidelity, sketching out ideas that, despite their rudimentary nature, easily spark debate. Other designers take time to create more fully-realised versions. Some even argue that the great unveiling should be eliminated altogether by working directly alongside the client throughout, collaborating on the design to reach its full potential. 

Whatever your individual preference, you’ll rarely have the chance to do it entirely your own way. Contracts, clients, and deadlines will affect how early and often you share your work. However, try to avoid the trap of presenting too late and at too high fidelity. My experience has taught me that skilled designers tend to present their work earlier and allow longer for iteration than novices do. More aware of the potential flaws in their solutions, these designers cling less tightly to their initial efforts. Working roughly and seeking early feedback gives you the flexibility to respond more fully to nuances you may have missed until now.

Planning design reviews

Present design ideas face-to-face, or at least via video conference. Asynchronous methods like e-mail and Basecamp are slow, easily ignored, and deny you the opportunity to guide your colleagues through your work. In person, you profit from both the well-known benefits of non-verbal communication, and the chance to immediately respond to questions and elaborate on rationale.

Be sure to watch the numbers at your design review sessions, however. Any more than a handful of attendees and the meeting could quickly spiral into fruitless debate. Ask your project sponsor to appoint a representative to speak on behalf of each business function, rather than inviting too many cooks.

Where possible, show your work in its native format. Photocopy hand-drawn sketches to reinforce their disposability (the defining quality of a sketch) and encourage others to scribble their own thoughts on top. Show digital deliverables – wireframes, design concepts, rich interactions – on screen. The experience of a design is very different on screen than on paper. A monitor has appropriate dimensions and viewport size, presenting an accurate picture of the design’s visual hierarchy, and putting interactive elements in the right context. On paper, a link is merely underlined text. On screen, it is another step along the user’s journey.

Don’t waste time presenting multiple concepts. Not only is it costly to work up multiple concepts to the level required for fair appraisal, but the practice demonstrates a sorry abdication of responsibility. Designers should be custodians of design. Asking for feedback on multiple designs turns the critique process into a beauty pageant, relinquishing a designer’s authority. Instead of rational choices that meet genuine user and business needs, you may be stuck with a Frankensteinian monstrosity, assembled from incompatible parts: “This header plus the whizzy bit from Version C”.

This isn’t to say that you shouldn’t explore lots of ideas yourself. Divergent thinking early in the design process is the only way to break free of the clichéd patterns and fads that so often litter mediocre sites. But you must act as a design curator, choosing the best of your work and explaining its rationale clearly and succinctly. Attitude, then, is central to successful critique. It can be difficult to tread the fine line between the harmful extremes of doormat passivity and prima donna arrogance. Remember that you are the professional, but be mindful that even experts make mistakes, particularly when – as with all design projects – they don’t possess all the relevant information in advance. Present your case with open-minded confidence, while accepting that positive critique will make your design (and ultimately your skills) stronger.

The courage of your convictions

Ultimately, your success in the feedback process, and indeed in the entire design process, hinges upon the rationale you provide for your work. Ideally, you should be able to refer to your research – personas, usability test findings, analytics – to support your decisions. To keep this evidence in mind, print it out to share at the design review, or include it in your presentation. Explain the rationale behind the most important decisions before showing the design, so that you can be sure of the full attention of your audience.

Once you’ve covered these points, display your design and walk through the specific features of the page. A little honesty goes a long way here: state your case as strongly as your rationale demands. Sure of your reasoning? Be strong. Speculating an approach based on a hunch? Say so, and encourage your colleagues to explore the idea with you and see where it leads.

Of course, none of these approaches should be sacrosanct. A proficient designer must be able to bend his or her way of working to suit the situation at hand. So sometimes you’ll want to ignore these rules of thumb and explore your own hunches as required. More power to you. As long as you think as clearly about the feedback process as you have about the design itself, you’ll be able to enjoy the great unveiling as a moment to be savoured, not feared.",2010,Cennydd Bowles,cennyddbowles,2010-12-12T00:00:00+00:00,https://24ways.org/2010/the-great-unveiling/,business
230,The Articulate Web Designer of Tomorrow,"You could say that we design to communicate, and that we seek emotive responses. It sounds straightforward, and it can be, but leaving it to chance isn’t wise. Many wander into web design without formal training, and whilst that certainly isn’t essential, we owe it to ourselves to draw on wider influences, learn from the past, and think smarter.

What knowledge can we ourselves explore in order to become better designers? In addition, how can we take this knowledge, investigate it through our unique discipline, and in turn speak more eloquently about what we do on the web? Below, I outline a number of things that I personally believe all designers should be using and exploring collectively.

Taking stock

Where we’re at is good. Finding clarity through web standards, we’ve ended up quite modernist in our approach, pursuing function, elegance and reduction. However, we’re not great at articulating our own design processes and principles to outsiders. Equally, we rely heavily on our instincts when deciding if something is or isn’t good. That’s fine, but we can better understand why things are the way they are by looking a little deeper, thereby helping us articulate what goes on in our design brains to our peers, our clients and to normal humans.

As designers we use ideas, concepts, text and images. We apply our ideas and experience, imposing order and structure to content, hoping to ease the communication of an idea to the largest possible audience or to a specific audience. We consciously manipulate most of what is available to us, but not all. There is something else we can use. I often think that brilliant work demands a keen understanding of the magical visual language that informs design.

Embracing an established visual language

This is a language whose alphabet is shapes, structures, colours, lines and rhythms. When effective, it is somewhat invisible, subliminally enforcing messages and evoking meaning, using methods solidly rooted in a grammar perceptible in virtually all extraordinary creative work. The syntax for art, architecture, film, and furniture, industrial and graphic design (think Bauhaus and the Swiss style perhaps), this language urges us to become fluent if we aim for a more powerful dialogue with our audience.

 Figure 1: Structures (clockwise from top-left): Informal; Formal; Active; Visible.

The greatest creative minds our world has produced could understand some or all of this language. Line and point, form and shape. Abstract objects. Formal and informal structures. Visual distribution. Balance, composition and the multitudinous approaches to symmetry. Patterns and texture. Movement and paths. Repetition, rhythm and frequency. Colour theory. Whitespace and the pause. The list goes on.

The genius we perceive in our creative heroes is often a composite of experience, trial and error, conviction, intuition – even accident – but rarely does great work arise without an initial understanding of the nuts and bolts that help communicate an idea or emotion.

Our world of interactivity

As web designers, our connection with this language is most evident in graphic design. With more technological ease and power comes the responsibility to understand, wisely use, and be able to justify many of our decisions. We have moved beyond the scope of print into a world of interactivity, but we shouldn’t let go of any established principles without good reason.

 Figure 2: Understanding movement of objects in any direction along a defined path.

For example, immersion in this visual language can improve our implementation of CSS3 and JavaScript behaviour. With CSS3, we’ve seen a resurgence in CSS experimentation, some of which has been wonderful, but much of it has appeared clumsy. In the race to make something spin, twist, flip or fly from one corner to another, the designer sometimes fails to think about the true movement they seek to emulate. What forces are supposedly affecting this movement? What is the expected path of this transition and is it being respected?

Stopping to think about what is really supposed to be happening on the page compels us to use complex animations, diagrams and rotations more carefully. It helps us to better understand paths and movement.

 Figure 3: Repetition can occur through variations in colour, shape, direction, and so on.

It can only be of greater benefit to be mindful of symmetries, depth, affordance, juxtaposition, balance, economy and reduction. A deeper understanding of basic structures can help us to say more with sketches, wireframes, layouts and composition. We’ve all experimented with grids and rhythm but, to truly benefit from these long-established principles, we are duty-bound to understand their possibilities more than we will by simply leveraging a free framework or borrowing some CSS.

Design is not a science, but…

Threading through all of this is what we have learned from science, and what it teaches us of the human brain. This visual language matters because technology changes but, for the most part, people don’t. For centuries, we humans have received and interpreted information in much the same way. Understanding more of how we perceive meaning can help designers make smarter decisions, and call on visual language to underpin these decisions. It is our responsibility as designers to be aware of mental models, mapping, semiotics, sensory experience and human emotion.

Design itself is not a science, but the appropriate use of visual language and scientific understanding exposes the line between effective and awkward, between communicative and mute. By strengthening our mental and analytical approach to what is often done arbitrarily or “because it feels right”, we simply become better designers.

A visual language for the web

So, I’ve outlined numerous starting points and areas worthy of deeper investigation, and hopefully you’re eager to do some research. However, I’ve mostly discussed established ideas and principles that we as web designers can learn from. It’s my belief that our community has a shared responsibility to expand this visual language as it applies to the ebb and flow of the web. Indulge me as I conclude with a related tangent.

In defining a visual language specifically for the web, we must continue to mature. The old powerfully influences the new, but we must intelligently expand the visual language of masterful work and articulate what is uniquely ours.

For example, phrases like Ethan Marcotte’s Responsive Web Design aren’t merely elegant, they describe a new way of thinking and working, of communicating about designs and interaction patterns. These phrases broaden our vocabulary and are immediately adopted by designers worldwide, in both conversation and execution.

Our legacy

Our new definitions should flex and not be tied to specific devices or methods which fade away or morph with time. Our legacy is perhaps more about robust and flexible patterns and systems than it is about specific devices or programming languages.

 Figure 4: As web designers, we should think about systems, not pages.

The established principles we adopt and whatever new ways of thinking we define should slip neatly into a wider philosophy about our approach to web design. We’re called, as a community, to define what is distinctive about the visual language of the web, create this vocabulary, this dialect that resonates with us and moves us forward as we tackle each day’s work. Let’s give it some thought.

Further reading

This is my immediate “go-to” list of books that I bullishly believe all web designers should own, but there is so much more out there to read. Sadly, many great texts relating to this stuff are often out of print. Feel free to share your recommendations.

219,Speed Up Your Site with Delayed Content,"Speed remains one of the most important factors influencing the success of any website, and the first rule of performance (according to Yahoo!) is reducing the number of HTTP requests. Over the last few years we’ve seen techniques like sprites and combo CSS/JavaScript files used to reduce the number of HTTP requests. But there’s one area where large numbers of HTTP requests are still a fact of life: the small avatars attached to the comments on articles like this one.

Avatars

Many sites like 24 ways use a fantastic service called Gravatar to provide user images. As a user, you can sign up to Gravatar, give them your e-mail address, and upload an image to represent you. Sites can then include your image by generating a one way hash of your e-mail address and using that to build an image URL. For example, the markup for the comments on this page looks something like this:

<div>
	<h4><a href=""http://allinthehead.com/"">
		<img src=""http://www.gravatar.com/avatar.php?gravatar_id=13734b0cb20708f79e730809c29c3c48&size=100"" class=""gravatar"" alt="""" height=""100"" width=""100"" />
    Drew McLellan
	</a></h4>
	<p>This is a great article!</p>
</div>

The Gravatar URL contains two parts. 100 is the size in pixels of the image we want.  13734b0cb20708f79e730809c29c3c48 is an MD5 digest of Drew’s e-mail address. Using MD5 means we can request an image for a user without sharing their e-mail address with anyone who views the source of the page.

So what’s wrong with avatars?

The problem is that a popular article can easily get hundreds of comments, and every one of them means another image has to be individually requested from Gravatar’s servers. Each request is small and the Gravatar servers are fast but, when you add them up, it can easily add seconds to the rendering time of a page. Worse, they can delay the loading of more important assets like the CSS required to render the main content of the page.

These images aren’t critical to the page, and don’t need to be loaded up front. Let’s see if we can delay loading them until everything else is done. That way we can give the impression that our site has loaded quickly even if some requests are still happening in the background.

Delaying image loading

The first problem we find is that there’s no way to prevent Internet Explorer, Chrome or Safari from loading an image without removing it from the HTML itself. Tricks like removing the images on the fly with JavaScript don’t work, as the browser has usually started requesting the images before we get a chance to stop it.

Removing the images from the HTML means that people without JavaScript enabled in their browser won’t see avatars. As Drew mentioned at the start of the month, this can affect a large number of people, and we can’t completely ignore them. But most sites already have a textual name attached to each comment and the avatars are just a visual enhancement. In most cases it’s OK if some of our users don’t see them, especially if it speeds up the experience for the other 98%.

Removing the images from the source of our page also means we’ll need to put them back at some point, so we need to keep a record of which images need to be requested. All Gravatar images have the same URL format; the only thing that changes is the e-mail hash. Storing this is a great use of HTML5 data attributes.

HTML5 data what?

Data attributes are a new feature in HTML5. The latest version of the spec says:


	A custom data attribute is an attribute in no namespace whose name starts with the string “data-”, has at least one character after the hyphen, is XML-compatible, and contains no characters in the range U+0041 to U+005A (LATIN CAPITAL LETTER A to LATIN CAPITAL LETTER Z).
[…]
Custom data attributes are intended to store custom data private to the page or application, for which there are no more appropriate attributes or elements. These attributes are not intended for use by software that is independent of the site that uses the attributes.


In other words, they’re attributes of an HTML element that start with “data-” which you can use to share data with scripts running on your site. They’re great for adding small bits of metadata that don’t fit into an existing markup pattern the way microformats do.

Let’s see this in action

Take a look at the markup for comments again:

<div>
	<h4><a href=""http://allinthehead.com/"">
		<img src=""http://www.gravatar.com/avatar.php?gravatar_id=13734b0cb20708f79e730809c29c3c48&size=100"" class=""gravatar"" alt="""" height=""100"" width=""100"" />
    Drew McLellan
	</a></h4>
	<p>This is a great article!</p>
</div>

Let’s replace the <img> element with a data-gravatar-hash attribute on the <a> element:

<div>
	<h4><a href=""http://allinthehead.com/"" data-gravatar-hash=""13734b0cb20708f79e730809c29c3c48"">
    Drew McLellan
	</a></h4>
	<p>This is a great article!</p>
</div>

Once we’ve done this, we’ll need a small bit of JavaScript to find all these attributes, and replace them with images after the page has loaded. Here’s an example using jQuery:

$(window).load(function() {
	$('a[data-gravatar-hash]').prepend(function(index){
		var hash = $(this).attr('data-gravatar-hash')
		return '<img width=""100"" height=""100"" alt="""" src=""http://www.gravatar.com/avatar.php?size=100&gravatar_id=' + hash + '"">'
	})
})

This code waits until everything on the page is loaded, then uses jQuery.prepend to insert an image into every link containing a data-gravatar-hash attribute. It’s short and relatively simple, but in tests it reduced the rendering time of a sample page from over three seconds to well under one.

Finishing touches

We still need to consider the appearance of the page before the avatars have loaded. When our script adds extra content to the page it will cause a browser reflow, which is visually annoying. We can avoid this by using CSS to reserve some space for each image before it’s inserted into the HTML:

#comments div {
	padding-left: 110px;
	min-height: 100px;
	position: relative;
}
#comments div h4 img {
	display: block;
	position: absolute;
	top: 0;
	left: 0;
}

In a real world example, we’ll also find that the HTML for a comment is more varied as many users don’t provide a web page link. We can make small changes to our JavaScript and CSS to handle this case.

Put this all together and you get this example.

Taking this idea further

There’s no reason to limit this technique to sites using Gravatar; we can use similar code to delay loading any images that don’t need to be present immediately. For example, this year’s redesigned Flickr photo page uses a “data-defer-src” attribute to describe any image that doesn’t need to be loaded straight away, including avatars and map tiles.

You also don’t have to limit yourself to loading the extra resources once the page loads. You can get further bandwidth savings by waiting until the user takes an action before downloading extra assets. Amazon has taken this tactic to the extreme on its product pages – extra content is loaded as you scroll down the page.

So next time you’re building a page, take a few minutes to think about which elements are peripheral and could be delayed to allow more important content to appear as quickly as possible.",2010,Paul Hammond,paulhammond,2010-12-18T00:00:00+00:00,https://24ways.org/2010/speed-up-your-site-with-delayed-content/,ux
229,Sketching to Communicate,"As a web designer I’ve always felt that I’d somehow cheated the system, having been absent on the day God handed out the ability to draw. I didn’t study fine art, I don’t have a natural talent to effortlessly knock out a realistic bowl of fruit beside a water jug, and yet somehow I’ve still managed to blag my way this far. I’m sure many of you may feel the same.

I had no intention of becoming an artist, but to have enough skill to convey an idea in a drawing would be useful. Instead, my inadequate instrument would doodle drunkenly across the page leaving a web of unintelligible paths instead of the refined illustration I’d seen in my mind’s eye. This – and the natural scrawl of my handwriting – is fine (if somewhat frustrating) when it’s for my eyes only but, when sketching to communicate a concept to a client, such amateur art would be offered with a sense of embarrassment. So when I had the opportunity to take part in some sketching classes whilst at Clearleft I jumped at the chance.

Why sketch?

In UX workshops early on in a project’s life, sketching is a useful and efficient way to convey and record ideas. It’s disposable and inexpensive, but needn’t look amateur. A picture may be worth a thousand words, but a well executed sketch of how you’ll combine funny YouTube videos with elephants to make Lolephants.com could be worth millions in venture capital. Actually, that’s not bad… ;-)

Although (as you will see) the basics of sketching are easy to master, the kudos you will receive from clients for being a ‘proper designer’ makes it worthwhile!

Where to begin?

Start by not buying yourself a sketch pad. If you were the type of child who ripped the first page out of a school exercise book and started again if you made even a tiny mistake (you’re not alone!), Wreck This Journal may offer a helping hand. Practicing on plain A4 paper instead of any ‘special’ notepad will make the process a whole lot easier, no matter how deliciously edible those Moleskines look.

Do buy yourself a black fine-liner pen and a set of grey Pro Markers for shading. These pens are unlike any you will have used before, and look like blended watercolours once the ink is dry. Although multiple strokes won’t create unsightly blotches of heavy ink on the page, they will go right through your top sheet so always remember to keep a rough sheet in the second position as an ink blotter.

 photo by Tom Harrison

Don’t buy pencils to sketch with, as they lack the confidence afforded by the heavy black ink strokes of marker pens and fine-liners.

If you’re going to be sketching with clients then invest in some black markers and larger sheets of paper. At the risk of sounding like a stationery brand whore, Sharpies are ideal, and these comedy-sized Post-Its do the job far better than cheaper, less sticky alternatives. Although they’re thicker than most standard paper, be sure to double-layer them if you’re writing on them on a wall, unless you fancy a weekend redecorating your client’s swanky boardroom.

The best way to build confidence and improve your sketching technique is, obviously, to practise. Reading this article will be of no help unless you repeat the following examples several times each. Go grab a pen and some paper now, and notice how you improve within even a short period of time.

Sketching web UI

Most elements of any website can be drawn as a combination of geometric shapes.

 photo by Nathanael Boehm

Circles

To draw a circle, get in position and start by resting your hand on the page and making the circular motion a few times without putting pen to paper. As you lower your pen whilst continuing the motion, you should notice the resulting shape is more regular than it otherwise would have been.

Squares and rectangles

Draw one pair of parallel lines first, followed by the others to complete the shapes. Slightly overlap the ends of the lines to make corners feel more solid than if you were to leave gaps. If you’re drawing a container, always draw the contents first, that way it won’t be a squash to fit them in. If you’re drawing a grid (of thumbnails, for instance), draw all parallel lines first as a series of long dashes to help keep line lengths and angles consistent.



Shadows

To lift elements from the page for emphasis, add a subtle shadow with a grey marker. For the most convincing look, assume the light source to be at the top left of the page – the shadow should simply be a thick grey line along the bottom and up the right edge of your shape. If the shape is irregular, the shadow should follow its outline. This is a good way to emphasise featured items, speech bubbles, form buttons, and so on.



Sketching ideas

Arrows

Use arrows to show steps in a process or direction of movement. Giving shadows a 3-D feel, or adding a single colour, will help separate them from the rest of the sketch.



Faces

Start by drawing the circle. The direction of the nose (merely a point) indicates the direction of the person’s gaze. The eyes and mouth show emotion: more open and curvy for happy thoughts; more closed and jagged for angry thoughts. Try out a few shapes and see what emotions they convey.



People

Remember, we’re aiming for communication rather than realism here. A stick man would be fine. Give him a solid body, as shown in this example, and it becomes easier to pose him.



I know you think hands are hard, but they’re quite important to convey some ideas, and for our purposes we don’t need to draw hands with any detail. An oval with a stick does the job of a pointing hand. Close-ups might need more fingers showing, but still don’t require any degree of realism.

Signage

Don’t be afraid to use words. We’re sketching to communicate, so if the easiest way to show an office block is a building with a big ‘office’ sign on the roof, that’s fine!



Labels

Likewise, feel free to label interactions. Use upper-case letters for legibility and slightly angle the horizontal bars upwards to create a more positive feel.

Clichés

Clichés are your friend! Someone’s having an idea? Light bulb above the head. Computer’s crashed? Cloud of smoke with “$£%*!”





It’s good to practise regularly. Try applying these principles to still life, too. Look around you now and draw the cup on the table, or the books on the shelf. Think of it as a combination of shapes and aim for symbolism rather than realism, and it’s not as hard as you’d think.

I hope this has given you the confidence to give it a shot, and the ability to at least not be mortified with the results!

Tip: If you’re involving clients in design games like Leisa Reichelt’s ‘Design Consequences’ it may be wise to tone down the quality of your drawings at that point so they don’t feel intimidated. Remember, it’s important for them to feel at ease with the idea of wireframing in front of you and their colleagues, no matter how bad their line work.

235,"Real Animation Using JavaScript, CSS3, and HTML5 Video","When I was in school to be a 3-D animator, I read a book called Timing for Animation. Though only 152 pages long, it’s essentially the bible for anyone looking to be a great animator. In fact, Pixar chief creative officer John Lasseter used the first edition as a reference when he was an animator at Walt Disney Studios in the early 1980s.

In the book, authors John Halas and Harold Whitaker advise:


	Timing is the part of animation which gives meaning to movement. Movement can easily be achieved by drawing the same thing in two different positions and inserting a number of other drawings between the two. The result on the screen will be movement; but it will not be animation.


But that’s exactly what we’re doing with CSS3 and JavaScript: we’re moving elements, not animating them. We’re constantly specifying beginning and end states and allowing the technology to interpolate between the two. And yet, it’s the nuances within those middle frames that create the sense of life we’re looking for.

As bandwidth increases and browser rendering grows more consistent, we can create interactions in different ways than we’ve been able to before. We’re encountering motion more and more on sites we’d generally label ‘static.’ However, this motion is mostly just movement, not animation. It’s the manipulation of an element’s properties, most commonly width, height, x- and y-coordinates, and opacity.

So how do we create real animation?

The metaphor

In my experience, animation is most believable when it simulates, exaggerates, or defies the real world. A bowling ball falls differently than a racquetball. They each have different weights and sizes, which affect the way they land, bounce, and impact other objects.

This is a major reason that JavaScript animation frequently feels mechanical; it doesn’t complete a metaphor. Expanding and collapsing a <div> feels very different than a opening a door or unfolding a piece of paper, but it often shouldn’t. The interaction itself should tie directly to the art direction of a page.

Physics

Understanding the physics of a situation is key to creating convincing animation, even if your animation seeks to defy conventional physics. Isaac Newton’s first law of motion’s_laws_of_motion states, “Every body remains in a state of rest or uniform motion (constant velocity) unless it is acted upon by an external unbalanced force.” Once a force acts upon an object, the object’s shape can change accordingly, depending on the strength of the force and the mass of the object. Another nugget of wisdom from Halas and Whitaker:


	All objects in nature have their own weight, construction, and degree of flexibility, and therefore each behaves in its own individual way when a force acts upon it. This behavior, a combination of position and timing, is the basis of animation. The basic question which an animator is continually asking himself is this: “What will happen to this object when a force acts upon it?” And the success of his animation largely depends on how well he answers this question.


In animating with CSS3 and JavaScript, keep physics in mind. How ‘heavy’ is the element you’re interacting with? What kind of force created the action? A gentle nudge? A forceful shove? These subtleties will add a sense of realism to your animations and make them much more believable to your users.

Misdirection

Magicians often use misdirection to get their audience to focus on one thing rather than another. They fool us into thinking something happened that actually didn’t.

Animation is the same, especially on a screen. By changing the arrangement of pixels on screen at a fast enough rate, your eyes fool your mind into thinking an object is actually in motion. 

Another important component of misdirecting in animation is the use of multiple objects. Try to recall a cartoon where a character vanishes. More often, the character makes some sort of exaggerated motion (this is called anticipation) then disappears, and a puff a smoke follows. That smoke is an extra element, but it goes a long way into make you believe that character actually disappeared.

Very rarely does a vanishing character’s opacity simply go from one hundred per cent to zero. That’s not believable. So why do we do it with <div>s?

Armed with the ammunition of metaphors and misdirection, let’s code an example.

Shake, rattle, and roll

(These demos require at least a basic understanding of jQuery and CSS3. Run away if your’re afraid, or brush up on CSS animation and resources for learning jQuery. Also, these demos use WebKit-specific features and are best viewed in the latest version of Safari, so performance in other browsers may vary.)

We often see the design pattern of clicking a link to reveal content. Our “first demo”:”/examples/2010/real-animation/demo1/ shows us exactly that. It uses jQuery’s “ slideDown()”:http://api.jquery.com/slideDown/ method, as many instances do.

But what force acted on the <div> that caused it to open? Did pressing the button unlatch some imaginary hook? Did it activate an unlocking sequence with some gears?

Take 2

Our second demo is more explicit about what happens: the button fell on the <div> and shook its content loose. Here’s how it’s done. 

function clickHandler(){
	$('#button').addClass('animate');
	return false;
}

Clicking the link adds a class of animate to our button. That class has the following CSS associated with it:

<style>
	.animate {
		-webkit-animation-name: ANIMATE;
		-webkit-animation-duration: 0.25s;
		-webkit-animation-iteration-count: 1;
		-webkit-animation-timing-function: ease-in;
	}
	@-webkit-keyframes ANIMATE {
		from {
		top: 72px;
		}
		to {
			top: 112px;
		}
	}
</style>

In our keyframe definition, we’ve specified from and to states. This is great, because we can be explicit about how an object starts and finishes moving. 

What’s also extra handy is that these CSS keyframes broadcast events that you can react to with JavaScript. In this example, we’re listening to the webkitAnimationEnd event and opening the <div> only when the sequence is complete. Here’s that code.

function attachAnimationEventHandlers(){
	var wrap = document.getElementById('wrap');
	wrap.addEventListener('webkitAnimationEnd', function($e) {
		switch($e.animationName){
			case ""ANIMATE"" :
			openMain();
			break;
			default:
		}
	}, false);
}
function openMain(){
	$('#main .inner').slideDown('slow');
}

(For more info on handling animation events, check out the documentation at the Safari Reference Library.)

Take 3

The problem with the previous demo is that the subtleties of timing aren’t evident. It still feels a bit choppy.

For our third demo, we’ll use percentages instead of keywords so that we can insert as many points as we need to communicate more realistic timing. The percentages allow us to add the keys to well-timed animation: anticipation, hold, release, and reaction. 

<style>
	@-webkit-keyframes ANIMATE {
		0% {
			top: 72px;
		}
		40% { /* anticipation */
			top: 57px;
		}
		70% { /* hold */
			top: 56px;
		}
		80% { /* release */
			top: 112px;
		}
		100% { /* return */
			top: 72px;
		}
	}
</style>

Take 4

The button animation is starting to feel much better, but the reaction of the <div> opening seems a bit slow.

This fourth demo uses jQuery’s delay() method to time the opening precisely when we want it. Since we know the button’s animation is one second long and its reaction starts at eighty per cent of that, that puts our delay at 800ms (eighty per cent of one second). However, here’s a little pro tip: let’s start the opening at 750ms instead. The extra fifty milliseconds makes it feel more like the opening is a reaction to the exact hit of the button. Instead of listening for the webkitAnimationEnd event, we can start the opening as soon as the button is clicked, and the movement plays on the specified delay.

function clickHandler(){
	$('#button').addClass('animate');
	openMain();
	return false;
}
function openMain(){
	$('#main .inner').delay(750).slideDown('slow');
}

Take 5

We can tweak the timing of that previous animation forever, but that’s probably as close as we’re going to get to realistic animation with CSS and JavaScript. However, for some extra sauce, we could relegate the whole animation in our final demo to a video sequence which includes more nuances and extra elements for misdirection.

Here’s the basis of video replacement. Add a <video> element to the page and adjust its opacity to zero. Once the button is clicked, fade the button out and start playing the video. Once the video is finished playing, fade it out and bring the button back.

function clickHandler(){
	if($('#main .inner').is(':hidden')){
		$('#button').fadeTo(100, 0);
		$('#clickVideo').fadeTo(100, 1, function(){
			var clickVideo = document.getElementById('clickVideo');
			clickVideo.play();
			setTimeout(removeVideo, 2400);
			openMain();
		});
	}
	return false;
}
function removeVideo(){
	$('#button').fadeTo(500, 1);
	$('#clickVideo').fadeOut('slow');
}
function openMain(){
	$('#main .inner').delay(1100).slideDown('slow');
}

Wrapping up

I’m no JavaScript expert by any stretch. I’m sure a lot of you scripting wizards out there could write much cleaner and more efficient code, but I hope this gives you an idea of the theory behind more realistic motion with the technology we’re using most. This is just one model of creating more convincing animation, but you can create countless variations of this, including…


	Exporting <video> animations in 3-D animation tools or 2-D animation tools like Flash or After Effects
	Using <canvas> or SVG instead of <video>
	Employing specific JavaScript animation frameworks
	Making use of all the powerful properties of CSS Transforms and CSS Animation
	Trying out emerging CSS3 animation tools like Sencha Animator


If it wasn’t already apparent, these demos show an exaggerated example and probably aren’t practical in a lot of environments. However, there are a handful of great sites out there that honor animation techniques—metaphor, physics, and misdirection, among others—like Benjamin De Cock’s vCard, 20 Things I Learned About Browsers and the Web by Fantasy Interactive, and the Nike Snowboarding site by Ian Coyle and HEGA. They’re wonderful testaments to what you can do to aid interaction for users.

My goal was to show you the ‘why’ and the ‘how.’ Your charge is to discern the ‘where’ and the ‘when.’ Happy animating!",2010,Dan Mall,danmall,2010-12-15T00:00:00+00:00,https://24ways.org/2010/real-animation-using-javascript-css3-and-html5-video/,code
218,Put Yourself in a Corner,"Some backstory, and a shameful confession

For the first couple years of high school I was one of those jerks who made only the minimal required effort in school. Strangely enough, how badly I behaved in a class was always in direct proportion to how skilled I was in the subject matter. In the subjects where I was confident that I could pass without trying too hard, I would give myself added freedom to goof off in class.

Because I was a closeted lit-nerd, I was most skilled in English class. I’d devour and annotate required reading over the weekend, I knew my biblical and mythological allusions up and down, and I could give you a postmodern interpretation of a text like nobody’s business. But in class, I’d sit in the back and gossip with my friends, nap, or scribble patterns in the margins of my textbooks. I was nonchalant during discussion, I pretended not to listen during lectures. I secretly knew my stuff, so I did well enough on tests, quizzes, and essays. But I acted like an ass, and wasn’t getting the most I could out of my education.

The day of humiliation, but also epiphany

One day in Ms. Kaney’s AP English Lit class, I was sitting in the back doodling. An earbud was dangling under my sweater hood, attached to the CD player (remember those?) sitting in my desk. Because of this auditory distraction, the first time Ms. Kaney called my name, I barely noticed. I definitely heard her the second time, when she didn’t call my name so much as roar it. I can still remember her five feet frame stomping across the room and grabbing an empty desk. It screamed across the worn tile as she slammed it next to hers. She said, “This is where you sit now.” My face gets hot just thinking about it.

I gathered my things, including the CD player (which was now impossible to conceal), and made my way up to the newly appointed Seat of Shame. There I sat, with my back to the class, eye-to-eye with Ms. Kaney. From my new vantage point I couldn’t see my friends, or the clock, or the window. All I saw were Ms. Kaney’s eyes, peering at me over her reading glasses while I worked. In addition to this punishment, I was told that from now on, not only would I participate in class discussions, but I would serve detention with her once a week until an undetermined point in the future.

During these detentions, Ms. Kaney would give me new books to read, outside the curriculum, and added on to my normal homework. They ranged from classics to modern novels, and she read over my notes on each book. We’d discuss them at length after class, and I grew to value not only our private discussions, but the ones in class as well. After a few weeks, there wasn’t even a question of this being punishment. It was heaven, and I was more productive than ever.

To the point

Please excuse this sentimental story. It’s not just about honoring a teacher who cared enough to change my life, it’s really about sharing a lesson. The most valuable education Ms. Kaney gave me had nothing to do with literature. She taught me that I (and perhaps other people who share my special brand of crazy) need to be put in a corner to flourish. When we have physical and mental constraints applied, we  accomplish our best work.

For those of you still reading, now seems like a good time to insert a pre-emptive word of mediation. Many of you, maybe all of you, are self-disciplined enough that you don’t require the rigorous restrictions I use to maximize productivity. Also, I know many people who operate best in a stimulating and open environment. I would advise everyone to seek and execute techniques that work best for them. But, for those of you who share my inclination towards daydreams and digressions, perhaps you’ll find something useful in the advice to follow.

In which I pretend to be Special Agent Olivia Dunham

Now that I’m an adult, and no longer have Ms. Kaney to reign me in, I have to find ways to put myself in the corner. By rejecting distraction and shaping an environment designed for intense focus, I’m able to achieve improved productivity.

Lately I’ve been obsessed with the TV show Fringe, a sci-fi series about an FBI agent and her team of genius scientists who save the world (no, YOU’RE a nerd). There’s a scene in the show where the primary character has to delve into her subconscious to do extraordinary things, and she accomplishes this by immersing herself in a sensory deprivation tank. The premise is this: when enclosed in a space devoid of sound, smell, or light, she will enter a new plane of consciousness wherein she can tap into new levels of perception.

This might sound a little nuts, but to me this premise has some real-world application. When I am isolated from distraction, and limited to only the task at hand, I’m able to be productive on a whole new level. Since I can’t actually work in an airtight iron enclosure devoid of input, I find practical ways to create an interruption-free environment.

Since I work from home, many of my methods for coping with distractions wouldn’t be necessary for my office-bound counterpart. However for some of you 9-to-5-ers, the principles will still apply.

Consider your visual input

First, I have to limit my scope to the world I can (and need to) affect. In the largest sense, this means closing my curtains to the chaotic scene of traffic, birds, the post office, a convenience store, and generally lovely weather that waits outside my window. When the curtains are drawn and I’m no longer surrounded by this view, my sphere is reduced to my desk, my TV, and my cat. Sometimes this step alone is enough to allow me to focus. 

But, my visual input can be whittled down further still. For example, the desk where I usually keep my laptop is littered with twelve owl figurines, a globe, four books, a three-pound weight, and various nerdy paraphernalia (hard drives, Wacom tablets, unnecessary bluetooth accessories, and so on). It’s not so much a desk as a dumping ground for wacky flea market finds and impulse technology buys. Therefore, in addition to this Official Desk, I have an adult version of Ms. Kaney’s Seat of Shame. It’s a rusty old student’s desk I picked up at the Salvation Army, almost an exact replica of the model Ms. Kaney dragged across the classroom all those years ago.  This tiny reproduction Seat of Shame is literally in a corner, where my only view is a blank wall. When I truly need to focus, this is where I take refuge, with only a notebook and a pencil (and occasionally an iPad).

Find out what works for your ears

Even from my limited sample size of two people, I know there are lots of different ways to cope with auditory distraction. I prefer silence when focused on independent work, and usually employ some form of a white noise generator. I’ve yet to opt for the fancy ‘real’ white noise machines; instead, I use a desktop fan or our allergy filter machine. This is usually sufficient to block out the sounds of the dishwasher and the cat, which allows me to think only about the task of hand.

My boyfriend, the other half of my extensive survey, swears by another method. He  calls it The Wall of Sound, and it’s basically an intense blast of raucous music streamed directly into his head. The outcome of his technique is really the same as mine; he’s blocking out unexpected auditory input. If you can handle the grating sounds of noisy music while working, I suggest you give The Wall of Sound a try.

Don’t count the minutes

When I sat in the original Seat of Shame in lit class, I could no longer see the big classroom clock slowly ticking away the seconds until lunch. Without the marker of time, the class period often flew by. The same is true now when I work; the less aware of time I am, the less it feels like time is passing too quickly or slowly, and the more I can focus on the task (not how long it takes). 

Nowadays, to assist in my effort to forget the passing of time, I sometimes put a sticky note over the clock on my monitor. If I’m writing, I’ll use an app like WriteRoom, which blocks out everything but a simple text editor. 

There are situations when it’s not advisable to completely lose track of time. If I’m working on a project with an hourly rate and a tight scope, or if I need to be on time to a meeting or call, I don’t want to lose myself in the expanse of the day. In these cases, I’ll set an alarm that lets me know it’s time to reign myself back in (or on some days, take a shower).

Put yourself in a mental corner, too

When Ms. Kaney took action and forced me to step up my game, she had the insight to not just change things physically, but to challenge me mentally as well. She assigned me reading material outside the normal coursework, then upped the pressure by requiring detailed reports of the material. While this additional stress was sometimes uncomfortable, it pushed me to work harder than I would have had there been less of a demand. Just as there can be freedom in the limitations of a distraction-free environment, I’d argue there is liberty in added mental constraints as well.

Deadlines as a constraint

Much has been written about the role of deadlines in the creative process, and they seem to serve different functions in different cases. I find that deadlines usually act as an important constraint and, without them, it would be nearly impossible for me to ever consider a project finished. There are usually limitless ways to improve upon the work I do and, if there’s no imperative for me to be done at a certain point, I will revise ad infinitum. (Hence, the personal site redesign that will never end – Coming Soon, Forever!). But if I have a clear deadline in mind, there’s a point when the obsessive tweaking has to stop. I reach a stage where I have to gather up the nerve to launch the thing.

Putting the pro in procrastination

Sometimes I’ve found that my tendency to procrastinate can help my productivity. (Ducks, as half the internet throws things at her.) I understand the reasons why procrastination can be harmful, and why it’s usually a good idea to work diligently and evenly towards a goal. I try to divide my projects up in a practical way, and sometimes I even pull it off. But for those tasks where you work aimlessly and no focus comes, or you find that every other to-do item is more appealing, sometimes you’re forced to bring it together at the last moment. And sometimes, this environment of stress is a formula for magic. Often when I’m down to the wire and have no choice but to produce, my mind shifts towards a new level of clarity. There’s no time to endlessly browse for inspiration, or experiment with convoluted solutions that lead nowhere.

Obviously a life lived perpetually on the edge of a deadline would be a rather stressful one, so it’s not a state of being I’d advocate for everyone, all the time. But every now and then, the work done when I’m down to the wire is my best.

Keep one toe outside your comfort zone

When I’m choosing new projects to take on, I often seek out work that involves an element of challenge. Whether it’s a design problem that will require some creative thinking, or a coding project that lends itself to using new technology like HTML5, I find a manageable level of difficulty to be an added bonus. The tension that comes from learning a new skill or rethinking an old standby is a useful constraint, as it keeps the work interesting, and ensures that I continue learning.

There you have it

Well, I think I’ve spilled most of my crazy secrets for forcing my easily distracted brain to focus. As with everything we web workers do, there are an infinite number of ways to encourage productivity. I hope you’ve found a few of these to be helpful, and please share your personal techniques in the comments.

232,Optimize Your Web Design Workflow,"I’m not sure about you, but I still favour using Photoshop to create my designs for the web. I agree that this application, even with its never-ending feature set, is not the perfect environment to design websites in. The ideal application doesn’t exist yet, however, so until it does it’s maybe not such a bad idea to investigate ways to optimize our workflow.

Why use Photoshop?

It will probably not come as a surprise if I say that Photoshop and Illustrator are the applications that I know best and feel most comfortable and creative in. Some people prefer Fireworks for web design. Even though I understand people’s motivations, I still prefer Photoshop personally. On the occasions that I gave Fireworks a try, I ended up just using the application to export my images as slices, or to prepare a dummy for the client. For some reason, I’ve never been able to find my way in that app. There were always certain things missing that could only be done in either Photoshop or Illustrator, which bothered me.

Why not start in the browser?

These days, with CSS3 styling emerging, there are people who find it more efficient to design in the browser. I agree that at a certain point, once the basic design is all set and defined, you can jump right into the code and go from there. But the actual creative part, at least for me, needs to be done in an application such as Photoshop.

As a designer I need to be able to create and experiment with shapes on the fly, draw things, move them around, change colours, gradients, effects, and so on. I can’t see me doing this with code. I’m sure if I switch to markup too quickly, I might end up with a rather boxy and less interesting design. Once I start playing with markup, I leave my typical ‘design zone’. My brain starts thinking differently – more rational and practical, if you know what I mean; I start to structure and analyse how to mark up my design in the most efficient semantic way. When I design, I tend to let that go for a bit. I think more freely and not so much about the limitations, as it might hinder my creativity. Now that you know my motivations to stick with Photoshop for the time being, let’s see how we can optimize this beast.

Optimize your Photoshop workspace

In Photoshop CS5 you have a few default workspace options to choose from which can be found at the top right in the Application Bar (Window > Application Bar).



You can set up your panels and palettes the way you want, starting from the ‘Design’ workspace option, and save this workspace for future web work. Here is how I have set up things for when I work on a website design:



I have the layers palette open, and I keep the other palettes collapsed. Sometimes, when space permits, I open them all. For designers who work both on print and web, I think it’s worthwhile to save a workspace for both, or for when you’re doing photo retouching.

Set up a grid

When you work a lot with Shape Layers like I do, it’s really helpful to enable the Grid (View > Show > Grid) in combination with Snap to Grid (View > Snap To > Grid). This way, your vector-based work will be pixel-sharp, as it will always snap to the grid, and so you don’t end up with blurry borders.



To set up your preferred grid, go to Preferences > Guides, Grids and Slices. A good setting is to use ‘Gridline Every 10 pixels’ and ‘Subdivision 10’. You can switch it on and off at any time using the shortcut Cmd/Ctrl + ’.



It might also help to turn on Smart Guides (View > Show > Smart Guides).

Another important tip for making sure your Shape Layer boxes and other shapes are perfectly aligned to the pixel grid when you draw them is to enable Snap to Pixels. This option can be enabled in the Application bar in the Geometry options dropdown menu when you select one of the shape tools from the toolbox.



Use Shape Layers

To keep your design as flexible as possible, it’s a good thing to use Shape Layers wherever you can as they are scalable. I use them when I design for the iPhone. All my icons, buttons, backgrounds, illustrative graphics – they are all either Smart Objects placed from Illustrator, or Shape Layers. This way, the design is scalable for the retina display.



Use Smart Objects

Among the things I like a lot in Photoshop are Smart Objects. Smart Objects preserve an image’s source content with all its original characteristics, enabling you to perform non-destructive editing to the layer. For me, this is the ideal way of making my design flexible.



For example, a lot of elements are created in Illustrator and are purely vector-based. Placing these elements in Photoshop as Smart Objects (via copy and paste, or dragging from Illustrator into Photoshop) will keep them vector-based and scalable at all times without loss of quality.



Another way you could use Smart Objects is whenever you have repeating elements; for example, if you have a stream or list of repeating items. You could, for instance, create one, two or three different items (for the sake of randomness), make each one a Smart Object, and repeat them to create the list. Then, when you have to update, you need only change the Smart Object, and the update will be automatically applied in all its linked instances.

Turning photos into Smart Objects before you resize them is also worth considering – you never know when you’ll need that same photo just a bit bigger. It keeps things more flexible, as you leave room to resize the image at a later stage. I use this in combination with the Smart Filters a lot, as it gives me such great flexibility.



I usually use Smart Objects as well for the main sections of a web page, which are repeated across different pages of a site. So, for elements such as the header, footer and sidebar, it can be handy for bigger projects that are constantly evolving, where you have to create a lot of different pages in Photoshop.

You could save a template page that has the main sections set up as Smart Objects, always in their latest version. Each time you need to create new page, you can start from that template file. If you need to update an existing page because the footer (or sidebar, or header) has been updated, you can drag the updated Smart Object into this page. Although, do I wish Photoshop made it possible to have Smart Objects live as separate files, which are then linked to my different pages. Then, whenever I update the Smart Object, the pages are automatically updated next time I open the file. This is how linked files work in InDesign and Illustrator when you place a external image.

Use Layer Comps

In some situations, using Layer Comps can come in handy. I try to use them when the design consists of different states; for example, if there are hidden and show states of certain content, such as when content is shown after clicking a certain button. It can be useful to create a Layer Comp for each state. So, when you switch between the two Layer Comps, you’re switching between the two states.



It’s OK to move or hide content in each of these states, as well as apply different layer styles. I find this particularly useful when I need to save separate JPEG versions of each state to show to the client, instead of going over all the eye icons in the layers palette to turn the layers’ visibility on or off.



Create a set of custom colour swatches

I tend to use a distinct colour Swatches palette for each project I work on, by saving a separate Swatches palette in project’s folder (as an .ase file). You can do this through the palette’s dropdown menu, choosing Save Swatches for Exchange.



Selecting this option gives you the flexibility to load this palette in other Adobe applications like Illustrator, InDesign or Fireworks. This way, you have the colours of any particular project at hand. I name each colour, using the hexadecimal values.



Loading, saving or changing the view of the Swatches palette can be done via the palette’s dropdown menu. My preferred view is ‘Small List’ so I can see the hexadecimal values or other info I have added in the description.

I do wish Photoshop had the option of loading several different Styles palettes, so I could have two or more of them open at the same time, but each as a separate palette. This would be handy whenever I switch to another project, as I’m usually working on more than one project in a day. At the moment, you can only add a set of colours to the palette that is already open, which is frustrating and inefficient if you need to update the palette of a project separately.

Create a set of custom Styles

Just like saving a Swatches palette, I also always save the styles I apply in the Styles palette as a separate Styles file in the project’s folder when I work on a website design or design for iPhone/iPad. During the design process, I can save it each time styles are added. Again, though, it would be great if we could have different Styles palettes open at the same time.



Use a scratch file

What I also find particularly timesaving, when working on a large project, is using some kind of scratch file. By that, I mean a file that has elements in place that you reuse a lot in the general design. Think of buttons, icons and so on, that you need in every page or screen design. This is great for both web design work and iPad/iPhone work. 



Use the slice tool

This might not be something you think of at first, because you probably associate this way of working with ‘old-school’ table-based techniques. Still, you can apply your slice any way you want, keeping your way of working in mind. Just think about it for a second. If you use the slice tool, and you give each slice its proper filename, you don’t have to worry about it when you need to do updates on the slice or image. Photoshop will remember what the image of that slice is called and which ‘Save for Web’ export settings you’ve used for it. You can also export multiple slices all at once, or export only the ones you need using ‘Save selected slices’.



I hope this list of optimization tips was useful, and that they will help you improve and enjoy your time in Photoshop. That is, until the ultimate web design application makes its appearance.

240,My CSS Wish List,"I love Christmas. I love walking around the streets of London, looking at the beautifully decorated windows, seeing the shiny lights that hang above Oxford Street and listening to Christmas songs.

I’m not going to lie though. Not only do I like buying presents, I love receiving them too. I remember making long lists that I would send to Father Christmas with all of the Lego sets I wanted to get. I knew I could only get one a year, but I would spend days writing the perfect list.

The years have gone by, but I still enjoy making wish lists. And I’ll tell you a little secret: my mum still asks me to send her my Christmas list every year.

This time I’ve made my CSS wish list. As before, I’d be happy with just one present.

Before I begin…

… this list includes:


	things that don’t exist in the CSS specification (if they do, please let me know in the comments – I may have missed them);
	others that are in the spec, but it’s incomplete or lacks use cases and examples (which usually means that properties haven’t been implemented by even the most recent browsers).


Like with any other wish list, the further down I go, the more unrealistic my expectations – but that doesn’t mean I can’t wish. Some of the things we wouldn’t have thought possible a few years ago have been implemented and our wishes fulfilled (think multiple backgrounds, gradients and transformations, for example).

The list

Cross-browser implementation of font-size-adjust

When one of the fall-back fonts from your font stack is used, rather than the preferred (first) one, you can retain the aspect ratio by using this very useful property. It is incredibly helpful when the fall-back fonts are smaller or larger than the initial one, which can make layouts look less polished.

What font-size-adjust does is divide the original font-size of the fall-back fonts by the font-size-adjust value. This preserves the x-height of the preferred font in the fall-back fonts. Here’s a simple example:

p {
    font-family: Calibri, ""Lucida Sans"", Verdana, sans-serif;
    font-size-adjust: 0.47;
}

In this case, if the user doesn’t have Calibri installed, both Lucida Sans and Verdana will keep Calibri’s aspect ratio, based on the font’s x-height. This property is a personal favourite and one I keep pointing to.

Firefox supported this property from version three. So far, it’s the only browser that does. Fontdeck provides the font-size-adjust value along with its fonts, and has a handy tool for calculating it.

More control over overflowing text

The text-overflow property lets you control text that overflows its container. The most common use for it is to show an ellipsis to indicate that there is more text than what is shown. To be able to use it, the container should have overflow set to something other than visible, and white-space: nowrap:

div {
    white-space: nowrap;
    width: 100%;
    overflow: hidden;
    text-overflow: ellipsis;
}

This, however, only works for blocks of text on a single line. In the wish list of many CSS authors (and in mine) is a way of defining text-overflow: ellipsis on a block of multiple text lines. Opera has taken the first step and added support for the -o-ellipsis-lastline property, which can be used instead of ellipsis. This property is not part of the CSS3 spec, but we could certainly make good use of it if it were…

WebKit has -webkit-line-clamp to specify how many lines to show before cutting with an ellipsis, but support is patchy at best and there is no control over where the ellipsis shows in the text. Many people have spent time wrangling JavaScript to do this for us, but the methods used are very processor intensive, and introduce a JavaScript dependency.

Indentation and hanging punctuation properties

You might notice a trend here: almost half of the items in this list relate to typography. The lack of fine-grained control over typographical detail is a general concern among designers and CSS authors. Indentation and hanging punctuation fall into this category.

The CSS3 specification introduces two new possible values for the text-indent property: each-line; and hanging. each-line would indent the first line of the block container and each line after a forced line break; hanging would invert which lines are affected by the indentation.

The proposed hanging-punctuation property would allow us to specify whether opening and closing brackets and quotes should hang outside the edge of the first and last lines. The specification is still incomplete, though, and asks for more examples and use cases.

Text alignment and hyphenation properties

Following the typographic trend of this list, I’d like to add better control over text alignment and hyphenation properties. The CSS3 module on Generated Content for Paged Media already specifies five new hyphenation-related properties (namely: hyphenate-dictionary; hyphenate-before and hyphenate-after; hyphenate-lines; and hyphenate-character), but it is still being developed and lacks examples.

In the text alignment realm, the new text-align-last property allows you to define how the last line of a block (or a line just before a forced break) is aligned, if your text is set to justify. Its value can be: start; end; left; right; center; and justify. The text-justify property should also allow you to have more control over text set to text-align: justify but, for now, only Internet Explorer supports this.

calc()

This is probably my favourite item in the list: the calc() function. This function is part of the CSS3 Values and Units module, but it has only been implemented by Firefox (4.0). To take advantage of it now you need to use the Mozilla vendor code, -moz-calc().

Imagine you have a fluid two-column layout where the sidebar column has a fixed width of 240 pixels, and the main content area fills the rest of the width available. This is how you could create that using -moz-calc():

#main {
    width: -moz-calc(100% - 240px);
}

Can you imagine how many hacks and headaches we could avoid were this function available in more browsers? Transitions and animations are really nice and lovely but, for me, it’s the ability to do the things that calc() allows you to that deserves the spotlight and to be pushed for implementation.

Selector grouping with -moz-any()

The -moz-any() selector grouping has been introduced by Mozilla but it’s not part of any CSS specification (yet?); it’s currently only available on Firefox 4.

This would be especially useful with the way HTML5 outlines documents, where we can have any number of variations of several levels of headings within numerous types of containers (think sections within articles within sections…).

Here is a quick example (copied from the Mozilla blog post about the article) of how -moz-any() works. Instead of writing:

section section h1, section article h1, section aside h1,
section nav h1, article section h1, article article h1,
article aside h1, article nav h1, aside section h1,
aside article h1, aside aside h1, aside nav h1, nav section h1,
nav article h1, nav aside h1, nav nav h1, {
    font-size: 24px;
}

You could simply write:

-moz-any(section, article, aside, nav)
-moz-any(section, article, aside, nav) h1 {
    font-size: 24px;
}

Nice, huh?

More control over styling form elements

Some are of the opinion that form elements shouldn’t be styled at all, since a user might not recognise them as such if they don’t match the operating system’s controls. I partially agree: I’d rather put the choice in the hands of designers and expect them to be capable of deciding whether their particular design hampers or improves usability.

I would say the same idea applies to font-face: while some fear designers might go crazy and litter their web pages with dozens of different fonts, most welcome the freedom to use something other than Arial or Verdana.

There will always be someone who will take this freedom too far, but it would be useful if we could, for example, style the default Opera date picker:

<input type=""date"" />



or Safari’s slider control (think star movie ratings, for example):

<input type=""range"" min=""0"" max=""5"" step=""1"" value=""3"" />



Parent selector

I don’t think there is one CSS author out there who has never come across a case where he or she wished there was a parent selector. There have been many suggestions as to how this could work, but a variation of the child selector is usually the most popular:

article < h1 {
…
}

One can dream…

Flexible box layout

The Flexible Box Layout Module sounds a bit like magic: it introduces a new box model to CSS, allowing you to distribute and order boxes inside other boxes, and determine how the available space is shared.

Two of my favourite features of this new box model are:


	the ability to redistribute boxes in a different order from the markup
	the ability to create flexible layouts, where boxes shrink (or expand) to fill the available space


Let’s take a quick look at the second case. Imagine you have a three-column layout, where the first column takes up twice as much horizontal space as the other two:

<body>
        <section id=""main"">
        </section>
        <section id=""links"">
        </section>
        <aside>
        </aside>
</body>

With the flexible box model, you could specify it like this:

body {
    display: box;
    box-orient: horizontal;
}
#main {
    box-flex: 2;
}
#links {
    box-flex: 1;
}
aside {
    box-flex: 1;
}

If you decide to add a fourth column to this layout, there is no need to recalculate units or percentages, it’s as easy as that.

Browser support for this property is still in its early stages (Firefox and WebKit need their vendor prefixes), but we should start to see it being gradually introduced as more attention is drawn to it (I’m looking at you…). You can read a more comprehensive write-up about this property on the Mozilla developer blog.

It’s easy to understand why it’s harder to start playing with this module than with things like animations or other more decorative properties, which don’t really break your layouts when users don’t see them. But it’s important that we do, even if only in very experimental projects.

Nested selectors

Anyone who has never wished they could do something like the following in CSS, cast the first stone:

article {
    h1 { font-size: 1.2em; }
    ul { margin-bottom: 1.2em; }
}

Even though it can easily turn into a specificity nightmare and promote redundancy in your style sheets (if you abuse it), it’s easy to see how nested selectors could be useful. CSS compilers such as Less or Sass let you do this already, but not everyone wants or can use these compilers in their projects.

Every wish list has an item that could easily be dropped. In my case, I would say this is one that I would ditch first – it’s the least useful, and also the one that could cause more maintenance problems. But it could be nice.

Implementation of the ::marker pseudo-element

The CSS Lists module introduces the ::marker pseudo-element, that allows you to create custom list item markers. When an element’s display property is set to list-item, this pseudo-element is created.

Using the ::marker pseudo-element you could create something like the following:

Footnote 1:  Both John Locke and his father, Anthony Cooper, are
named after 17th- and 18th-century English philosophers; the real
Anthony Cooper was educated as a boy by the real John Locke.
Footnote 2:  Parts of the plane were used as percussion instruments
and can be heard in the soundtrack.

where the footnote marker is generated by the following CSS:

li::marker {
    content: ""Footnote "" counter(notes) "":"";
    text-align: left;
    width: 12em;
}
li {
    counter-increment: notes;
}

You can read more about how to use counters in CSS in my article from last year.

Bear in mind that the CSS Lists module is still a Working Draft and is listed as “Low priority”. I did say this wish list would start to grow more unrealistic closer to the end…

Variables

The sight of the word ‘variables’ may make some web designers shy away, but when you think of them applied to things such as repeated colours in your stylesheets, it’s easy to see how having variables available in CSS could be useful.

Think of a website where the main brand colour is applied to elements like the main text, headings, section backgrounds, borders, and so on. In a particularly large website, where the colour is repeated countless times in the CSS and where it’s important to keep the colour consistent, using variables would be ideal (some big websites are already doing this by using server-side technology).

Again, Less and Sass allow you to use variables in your CSS but, again, not everyone can (or wants to) use these.

If you are using Less, you could, for instance, set the font-family value in one variable, and simply call that variable later in the code, instead of repeating the complete font stack, like so:

@fontFamily: Calibri, ""Lucida Grande"", ""Lucida Sans Unicode"", Helvetica, Arial, sans-serif;
body {
    font-family: @fontFamily;
}

Other features of these CSS compilers might also be useful, like the ability to ‘call’ a property value from another selector (accessors):

header {
    background: #000000;
}
footer {
    background: header['background'];
}

or the ability to define functions (with arguments), saving you from writing large blocks of code when you need to write something like, for example, a CSS gradient:

.gradient (@start:"""", @end:"""") {
    background: -webkit-gradient(linear, left top, left bottom, from(@start), to(@end));
    background: -moz-linear-gradient(-90deg,@start,@end);
}
button {
    .gradient(#D0D0D0,#9F9F9F);
}

Standardised comments

Each CSS author has his or her own style for commenting their style sheets. While this isn’t a massive problem on smaller projects, where maybe only one person will edit the CSS, in larger scale projects, where dozens of hands touch the code, it would be nice to start seeing a more standardised way of commenting.

One attempt at creating a standard for CSS comments is CSSDOC, an adaptation of Javadoc (a documentation generator that extracts comments from Java source code into HTML). CSSDOC uses ‘DocBlocks’, a term borrowed from the phpDocumentor Project. A DocBlock is a human- and machine-readable block of data which has the following structure:

/**
 * Short description
 *
 * Long description (this can have multiple lines and contain <p> tags
 *
 * @tags (optional)
 */

CSSDOC includes a standard for documenting bug fixes and hacks, colours, versioning and copyright information, amongst other important bits of data.

I know this isn’t a CSS feature request per se; rather, it’s just me pointing you at something that is usually overlooked but that could contribute towards keeping style sheets easier to maintain and to hand over to new developers.

Final notes

I understand that if even some of these were implemented in browsers now, it would be a long time until all vendors were up to speed. But if we don’t talk about them and experiment with what’s available, then it will definitely never happen.

Why haven’t I mentioned better browser support for existing CSS3 properties? Because that would be the same as adding chocolate to your Christmas wish list – you don’t need to ask, everyone knows you want it.

The list could go on. There are dozens of other things I would love to see integrated in CSS or further developed. These are my personal favourites: some might be less useful than others, but I’ve wished for all of them at some point.

Part of the research I did while writing this article was asking some friends what they would add to their lists; other than a couple of items I already had in mine, everything else was different. I’m sure your list would be different too. So tell me, what’s on your CSS wish list?",2010,Inayaili de León Persson,inayailideleon,2010-12-03T00:00:00+00:00,https://24ways.org/2010/my-css-wish-list/,code
231,Designing for iOS: Life Beyond Media Queries,"Although not a new phenomenon, media queries seem to be getting a lot attention online recently and for the right reasons too – it’s great to be able to adapt a design with just a few lines of CSS – but many people are relying only on them to create an iPhone-specific version of their website. 

I was pleased to hear at FOWD NYC a few weeks ago that both myself and Aral Balkan share the same views on why media queries aren’t always going to be the best solution for mobile. Both of us specialise in iPhone design ourselves and we opt for a different approach to media queries. The trouble is, regardless of what you have carefully selected to be display:none; in your CSS, the iPhone still loads everything in the background; all that large imagery for your full scale website also takes up valuable mobile bandwidth and time.

You can greatly increase the speed of your website by creating a specific site tailored to mobile users with just a few handy pointers – media queries, in some instances, might be perfectly suitable but, in others, here’s what you can do.

Redirect your iPhone/iPod Touch users

To detect whether someone is viewing your site on an iPhone or iPod Touch, you can either use JavaScript or PHP. 

The JavaScript 

if((navigator.userAgent.match(/iPhone/i)) || (navigator.userAgent.match(/iPod/i))) { 
    if (document.cookie.indexOf(""iphone_redirect=false"") == -1) window.location = ""http://mobile.yoursitehere.com""; 
}

The PHP

if(strstr($_SERVER['HTTP_USER_AGENT'],'iPhone') || strstr($_SERVER['HTTP_USER_AGENT'],'iPod')) 
{
    header('Location: http://mobile.yoursitehere.com');
    exit();
}

Both of these methods redirect the user to a site that you have made specifically for the iPhone. At this point, be sure to provide a link to the full version of the website, in case the user wishes to view this and not be thrown into an experience they didn’t want, with no way back.

Tailoring your site

So, now you’ve got 320 × 480 pixels of screen to play with – and to create a style sheet for, just as you would for any other site you build. There are a few other bits and pieces that you can add to your code to create a site that feels more like a fully immersive iPhone app rather than a website.

Retina display

When building your website specifically tailored to the iPhone, you might like to go one step further and create a specific style sheet for iPhone 4’s Retina display. Because there are four times as many pixels on the iPhone 4 (640 × 960 pixels), you’ll find specifics such as text shadows and borders will have to be increased. 

<link rel=""stylesheet"" 
   media=""only screen and (-webkit-min-device-pixel-ratio: 2)"" 
   type=""text/css"" href=""../iphone4.css"" />

(Credit to Thomas Maier)

Prevent user scaling

This declaration, added into the <head>, stops the user being able to pinch-zoom in and out of your design, which is perfect if you are designing to the exact pixel measurements of the iPhone screen. 

<meta name=""viewport"" 
   content=""width=device-width; initial-scale=1.0; maximum-scale=1.0;"">

Designing for orientation 

As iPhones aren’t static devices, you’ll also need to provide a style sheet for horizontal orientation. We can do this by inserting some JavaScript into the <head> as follows: 

<script type=""text/javascript"">
function orient() {
    switch(window.orientation) {
        case 0: 
            document.getElementById(""orient_css"").href = ""css/iphone_portrait.css"";
            break;
        case -90: 
            document.getElementById(""orient_css"").href = ""css/iphone_landscape.css"";
            break;
        case 90: 
            document.getElementById(""orient_css"").href = ""css/iphone_landscape.css"";
            break;
    }
}
window.onload = orient();
</script>

You can also specify orientation styles using media queries. This is absolutely fine, as by this point you’ll already be working with mobile-specific graphics and have little need to set a lot of things to display:none;

<link rel=""stylesheet"" 
   media=""only screen and (max-device-width: 480px)"" href=""/iphone.css"">
<link rel=""stylesheet"" 
   media=""only screen and (orientation: portrait)"" href=""/portrait.css"">
<link rel=""stylesheet"" 
   media=""only screen and (orientation: landscape)” href=""/landscape.css"">

Remove the address and status bars, top and bottom

To give you more room on-screen and to make your site feel more like an immersive web app, you can place the following declaration into the <head> of your document’s code to remove the address and status bars at the top and bottom of the screen. 

<meta name=""apple-mobile-web-app-capable"" content=""yes"" />

Making the most of inbuilt functions

Similar to mailto: e-mail links, the iPhone also supports another two handy URI schemes which are great for enhancing contact details. When tapped, the following links will automatically bring up the appropriate call or text interface:

<a href=""tel:01234567890"">Call us</a>
<a href=""sms:01234567890"">Text us</a>

iPhone-specific Web Clip icon

Although I believe them to be fundamentally flawed, since they rely on the user bookmarking your site, iPhone Web Clip icons are still a nice touch. You need just two declarations, again in the <head> of your document:

<link rel=""apple-touch-icon"" href=""icons/regular_icon.png"" />
<link rel=""apple-touch-icon"" sizes=""114x114"" href=""icons/retina_icon.png"" />

For iPhone 4 you’ll need to create a 114 × 114 pixels icon; for a non-Retina display, a 57 × 57 pixels icon will do the trick.

Precomposed 

Apple adds its standard gloss ‘moon’ over the top of any icon. If you feel this might be too much for your particular icon and would prefer a matte finish, you can add precomposed to the end of the apple-touch-icon declaration to remove the standard gloss. 

<link rel=""apple-touch-icon-precomposed"" href=""/images/touch-icon.png"" />

Wrapping up

Media queries definitely have their uses. They make it easy to build a custom experience for your visitor, regardless of their browser’s size. For more complex sites, however, or where you have lots of imagery and other content that isn’t necessary on the mobile version, you can now use these other methods to help you out. Remember, they are purely for presentation and not optimisation; for busy people on the go, optimisation and faster-running mobile experiences can only be a good thing. 

Have a wonderful Christmas fellow Webbies!",2010,Sarah Parmenter,sarahparmenter,2010-12-17T00:00:00+00:00,https://24ways.org/2010/life-beyond-media-queries/,code
234,An Introduction to CSS 3-D Transforms,"Ladies and gentlemen, it is the second decade of the third millennium and we are still kicking around the same 2-D interface we got three decades ago. Sure, Apple debuted a few apps for OSX 10.7 that have a couple more 3-D flourishes, and Microsoft has had that Flip 3D for a while. But c’mon – 2011 is right around the corner. That’s Twenty Eleven, folks. Where is our 3-D virtual reality? By now, we should be zipping around the Metaverse on super-sonic motorbikes.

Granted, the capability of rendering complex 3-D environments has been present for years. On the web, there are already several solutions: Flash; three.js in <canvas>; and, eventually, WebGL. Finally, we meagre front-end developers have our own three-dimensional jewel: CSS 3-D transforms!

Rationale

Like a beautiful jewel, 3-D transforms can be dazzling, a true spectacle to behold. But before we start tacking 3-D diamonds and rubies to our compositions like Liberace‘s tailor, we owe it to our users to ask how they can benefit from this awesome feature. 

An entire application should not take advantage of 3-D transforms. CSS was built to style documents, not generate explorable environments. I fail to find a benefit to completing a web form that can be accessed by swivelling my viewport to the Sign-Up Room (although there have been proposals to make the web just that). Nevertheless, there are plenty of opportunities to use 3-D transforms in between interactions with the interface, via transitions.

Take, for instance, the Weather App on the iPhone. The application uses two views: a details view; and an options view. Switching between these two views is done with a 3-D flip transition. This informs the user that the interface has two – and only two – views, as they can exist only on either side of the same plane.

 Flipping from details view to options view via a 3-D transition

Also, consider slide shows. When you’re looking at the last slide, what cues tip you off that advancing will restart the cycle at the first slide? A better paradigm might be achieved with a 3-D transform, placing the slides side-by-side in a circle (carousel) in three-dimensional space; in that arrangement, the last slide obviously comes before the first.

3-D transforms are more than just eye candy. We can also use them to solve dilemmas and make our applications more intuitive. 

Current support

The CSS 3D Transforms module has been out in the wild for over a year now. Currently, only Safari supports the specification – which includes Safari on Mac OS X and Mobile Safari on iOS. 

The support roadmap for other browsers varies. The Mozilla team has taken some initial steps towards implementing the module. Mike Taylor tells me that the Opera team is keeping a close eye on CSS transforms, and is waiting until the specification is fleshed out. And our best friend Internet Explorer still needs to catch up to 2-D transforms before we can talk about the 3-D variety.

To make matters more perplexing, Safari’s WebKit cousin Chrome currently accepts 3-D transform declarations, but renders them in 2-D space. Chrome team member Paul Irish, says that 3-D transforms are on the horizon, perhaps in one of the next 8.0 releases.

This all adds up to a bit of a challenge for those of us excited by 3-D transforms. I’ll give it to you straight: missing the dimension of depth can make degradation a bit ungraceful. Unless the transform is relatively simple and holds up in non-3D-supporting browsers, you’ll most likely have to design another solution. But what’s another hurdle in a steeplechase? We web folk have had our mettle tested for years. We’re prepared to devise multiple solutions.

Here’s the part of the article where I mention Modernizr, and you brush over it because you’ve read this part of an article hundreds of times before. But seriously, it’s the best way to test for CSS 3-D transform support. Use it.

Even with these difficulties mounting up, trying out 3-D transforms today is the right move. The CSS 3-D transforms module was developed by the same team at Apple that produced the CSS 2D Transforms and Animation modules. Both specifications have since been adopted by Mozilla and Opera. Transforming in three-dimensions now will guarantee you’ll be ahead of the game when the other browsers catch up.

The choice is yours. You can make excuses and pooh-pooh 3-D transforms because they’re too hard and only snobby Apple fans will see them today. Or, with a tip of the fedora to Mr Andy Clarke, you can get hard-boiled and start designing with the best features out there right this instant.

So, I bid you, in the words of the eternal Optimus Prime…


	Transform and roll out.


Let’s get coding.

Perspective

To activate 3-D space, an element needs perspective. This can be applied in two ways: using the transform property, with the perspective as a functional notation:

-webkit-transform: perspective(600);

or using the perspective property: 

-webkit-perspective: 600;

See example: Perspective 1.



 The red element on the left uses transform: perspective() functional notation; the blue element on the right uses the perspective property



These two formats both trigger a 3-D space, but there is a difference. The first, functional notation is convenient for directly applying a 3-D transform on a single element (in the previous example, I use it in conjunction with a rotateY transform). But when used on multiple elements, the transformed elements don’t line up as expected. If you use the same transform across elements with different positions, each element will have its own vanishing point. To remedy this, use the perspective property on a parent element, so each child shares the same 3-D space.

See Example: Perspective 2.



 Each red box on the left has its own vanishing point within the parent container; the blue boxes on the right share the vanishing point of the parent container



The value of perspective determines the intensity of the 3-D effect. Think of it as a distance from the viewer to the object. The greater the value, the further the distance, so the less intense the visual effect. perspective: 2000; yields a subtle 3-D effect, as if we were viewing an object from far away. perspective: 100; produces a tremendous 3-D effect, like a tiny insect viewing a massive object.

By default, the vanishing point for a 3-D space is positioned at its centre. You can change the position of the vanishing point with perspective-origin property.

-webkit-perspective-origin: 25% 75%;

See Example: Perspective 3.







3-D transform functions

As a web designer, you’re probably well acquainted with working in two dimensions, X and Y, positioning items horizontally and vertically. With a 3-D space initialised with perspective, we can now transform elements in all three glorious spatial dimensions, including the third Z dimension, depth. 

3-D transforms use the same transform property used for 2-D transforms. If you’re familiar with 2-D transforms, you’ll find the basic 3D transform functions fairly similar. 


	rotateX(angle)
	rotateY(angle)
	rotateZ(angle)
	translateZ(tz)
	scaleZ(sz)


Whereas translateX() positions an element along the horizontal X-axis, translateZ() positions it along the Z-axis, which runs front to back in 3-D space. Positive values position the element closer to the viewer, negative values further away.

The rotate functions rotate the element around the corresponding axis. This is somewhat counter-intuitive at first, as you might imagine that rotateX will spin an object left to right. Instead, using rotateX(45deg) rotates an element around the horizontal X-axis, so the top of the element angles back and away, and the bottom gets closer to the viewer.

See Example: Transforms 1.



3-D rotate() and translate() functions around each axis



There are also several shorthand transform functions that require values for all three dimensions:


	translate3d(tx,ty,tz)
	scale3d(sx,sy,sz)
	rotate3d(rx,ry,rz,angle)


Pro-tip: These foo3d() transform functions also have the benefit of triggering hardware acceleration in Safari. Dean Jackson, CSS 3-D transform spec author and main WebKit dude, writes (to Thomas Fuchs):


	In essence, any transform that has a 3D operation as one of its functions will trigger hardware compositing, even when the actual transform is 2D, or not doing anything at all (such as translate3d(0,0,0)). Note this is just current behaviour, and could change in the future (which is why we don’t document or encourage it). But it is very helpful in some situations and can significantly improve redraw performance.


For the sake of simplicity, my demos will use the basic transform functions, but if you’re writing production-ready CSS for iOS or Safari-only, make sure to use the foo3d() functions to get the best rendering performance.

Card flip

We now have all the tools to start making 3-D objects. Let’s get started with something simple: flipping a card.

Here’s the basic markup we’ll need:

<section class=""container"">
  <div id=""card"">
    <figure class=""front"">1</figure>
    <figure class=""back"">2</figure>
  </div>
</section>

The .container will house the 3-D space. The #card acts as a wrapper for the 3-D object. Each face of the card has a separate element: .front; and .back. Even for such a simple object, I recommend using this same pattern for any 3-D transform. Keeping the 3-D space element and the object element(s) separate establishes a pattern that is simple to understand and easier to style.

We’re ready for some 3-D stylin’. First, apply the necessary perspective to the parent 3-D space, along with any size or positioning styles.

.container { 
  width: 200px;
  height: 260px;
  position: relative;
  -webkit-perspective: 800;
}

Now the #card element can be transformed in its parent’s 3-D space. We’re combining absolute and relative positioning so the 3-D object is removed from the flow of the document. We’ll also add width: 100%;  and height: 100%;. This ensures the object’s transform-origin will occur in the centre of .container. More on transform-origin later. 

Let’s add a CSS3 transition so users can see the transform take effect. 

#card {
  width: 100%;
  height: 100%;
  position: absolute;
  -webkit-transform-style: preserve-3d;
  -webkit-transition: -webkit-transform 1s;
}

The .container’s perspective only applies to direct descendant children, in this case #card. In order for subsequent children to inherit a parent’s perspective, and live in the same 3-D space, the parent can pass along its perspective with transform-style: preserve-3d. Without 3-D transform-style, the faces of the card would be flattened with its parents and the back face’s rotation would be nullified. 

To position the faces in 3-D space, we’ll need to reset their positions in 2-D with position: absolute. In order to hide the reverse sides of the faces when they are faced away from the viewer, we use backface-visibility: hidden. 

#card figure {
  display: block;
  position: absolute;
  width: 100%;
  height: 100%;
  -webkit-backface-visibility: hidden;
}

To flip the .back face, we add a basic 3-D transform of rotateY(180deg). 

#card .front {
  background: red;
}
#card .back {
  background: blue;
  -webkit-transform: rotateY(180deg);
}

With the faces in place, the #card requires a corresponding style for when it is flipped.

#card.flipped {
  -webkit-transform: rotateY(180deg);
}

Now we have a working 3-D object. To flip the card, we can toggle the flipped class. When .flipped, the #card will rotate 180 degrees, thus exposing the .back face.

See Example: Card 1.



Flipping a card in three dimensions



Slide-flip

Take another look at the Weather App 3-D transition. You’ll notice that it’s not quite the same effect as our previous demo. If you follow the right edge of the card, you’ll find that its corners stay within the container. Instead of pivoting from the horizontal centre, it pivots on that right edge. But the transition is not just a rotation – the edge moves horizontally from right to left. We can reproduce this transition just by modifying a couple of lines of CSS from our original card flip demo.

The pivot point for the rotation occurs at the right side of the card. By default, the transform-origin of an element is at its horizontal and vertical centre (50% 50% or center center). Let’s change it to the right side:

#card { -webkit-transform-origin: right center; }

That flip now needs some horizontal movement with translateX. We’ll set the rotation to -180deg so it flips right side out.

#card.flipped {
  -webkit-transform: translateX(-100%) rotateY(-180deg);
}

See Example: Card 2.



Creating a slide-flip from the right edge of the card



Cube

Creating 3-D card objects is a good way to get started with 3-D transforms. But once you’ve mastered them, you’ll be hungry to push it further and create some true 3-D objects: prisms. We’ll start out by making a cube.

The markup for the cube is similar to the card. This time, however, we need six child elements for all six faces of the cube:

<section class=""container"">
  <div id=""cube"">
    <figure class=""front"">1</figure>
    <figure class=""back"">2</figure>
    <figure class=""right"">3</figure>
    <figure class=""left"">4</figure>
    <figure class=""top"">5</figure>
    <figure class=""bottom"">6</figure>
  </div>
</section>

Basic position and size styles set the six faces on top of one another in the container.

.container {
  width: 200px;
  height: 200px;
  position: relative;
  -webkit-perspective: 1000;
}
#cube {
  width: 100%;
  height: 100%;
  position: absolute;
  -webkit-transform-style: preserve-3d;
}
#cube figure {
  width: 196px;
  height: 196px;
  display: block;
  position: absolute;
  border: 2px solid black;
}

With the card, we only had to rotate its back face. The cube, however, requires that five of the six faces to be rotated. Faces 1 and 2 will be the front and back. Faces 3 and 4 will be the sides. Faces 5 and 6 will be the top and bottom.

#cube .front { -webkit-transform: rotateY(0deg); }
#cube .back { -webkit-transform: rotateX(180deg); }
#cube .right { -webkit-transform: rotateY(90deg); }
#cube .left { -webkit-transform: rotateY(-90deg); }
#cube .top { -webkit-transform: rotateX(90deg); }
#cube .bottom { -webkit-transform: rotateX(-90deg); }

We could remove the first #cube .front style declaration, as this transform has no effect, but let’s leave it in to keep our code consistent.

Now each face is rotated, and only the front face is visible. The four side faces are all perpendicular to the viewer, so they appear invisible. To push them out to their appropriate sides, they need to be translated out from the centre of their positions. Each side of the cube is 200 pixels wide. From the cube’s centre they’ll need to be translated out half that distance, 100px.

#cube .front { -webkit-transform: rotateY(0deg) translateZ(100px); }
#cube .back { -webkit-transform: rotateX(180deg) translateZ(100px); }
#cube .right { -webkit-transform: rotateY(90deg) translateZ(100px); }
#cube .left { -webkit-transform: rotateY(-90deg) translateZ(100px); }
#cube .top { -webkit-transform: rotateX(90deg) translateZ(100px); }
#cube .bottom { -webkit-transform: rotateX(-90deg) translateZ(100px); }

Note here that the translateZ function comes after the rotate. The order of transform functions is important. Take a moment and soak this up. Each face is first rotated towards its position, then translated outward in a separate vector.

We have a working cube, but we’re not done yet.

Returning to the Z-axis origin

For the sake of our users, our 3-D transforms should not distort the interface when the active panel is at its resting position. But once we start pushing elements off their Z-axis origin, distortion is inevitable. 

In order to keep 3-D transforms snappy, Safari composites the element, then applies the transform. Consequently, anti-aliasing on text will remain whatever it was before the transform was applied. When transformed forward in 3-D space, significant pixelation can occur. 

See Example: Transforms 2.







Looking back at the Perspective 3 demo, note that no matter how small the perspective value is, or wherever the transform-origin may be, the panel number 1 always returns to its original position, as if all those funky 3-D transforms didn’t even matter.

To resolve the distortion and restore pixel perfection to our #cube, we can push the 3-D object back, so that the front face will be positioned back to the Z-axis origin.

#cube { -webkit-transform: translateZ(-100px); }

See Example: Cube 1.



Restoring the front face to the original position on the Z-axis



Rotating the cube

To expose any face of the cube, we’ll need a style that rotates the cube to expose any face. The transform values are the opposite of those for the corresponding face. We toggle the necessary class on the #box to apply the appropriate transform.

#cube.show-front { -webkit-transform: translateZ(-100px) rotateY(0deg); }
#cube.show-back { -webkit-transform: translateZ(-100px) rotateX(-180deg); }
#cube.show-right { -webkit-transform: translateZ(-100px) rotateY(-90deg); }
#cube.show-left { -webkit-transform: translateZ(-100px) rotateY(90deg); }
#cube.show-top { -webkit-transform: translateZ(-100px) rotateX(-90deg); }
#cube.show-bottom { -webkit-transform: translateZ(-100px) rotateX(90deg); }

Notice how the order of the transform functions has reversed. First, we push the object back with translateZ, then we rotate it.

Finishing up, we can add a transition to animate the rotation between states. 

#cube { -webkit-transition: -webkit-transform 1s; }

See Example: Cube 2.



Rotating the cube with a CSS transition



Rectangular prism

Cubes are easy enough to generate, as we only have to worry about one measurement. But how would we handle a non-regular rectangular prism? Let’s try to make one that’s 300 pixels wide, 200 pixels high, and 100 pixels deep. 

The markup remains the same as the #cube, but we’ll switch the cube id for #box. The container styles remain mostly the same:

.container {
  width: 300px;
  height: 200px;
  position: relative;
  -webkit-perspective: 1000;
}
#box {
  width: 100%;
  height: 100%;
  position: absolute;
  -webkit-transform-style: preserve-3d;
}

Now to position the faces. Each set of faces will need their own sizes. The smaller faces (left, right, top and bottom) need to be positioned in the centre of the container, where they can be easily rotated and then shifted outward. The thinner left and right faces get positioned left: 100px ((300 − 100) ÷ 2), The stouter top and bottom faces get positioned top: 50px ((200 − 100) ÷ 2).

#box figure {
  display: block;
  position: absolute;
  border: 2px solid black;
}
#box .front,
#box .back {
  width: 296px;
  height: 196px;
}
#box .right,
#box .left {
  width: 96px;
  height: 196px;
  left: 100px;
}
#box .top,
#box .bottom {
  width: 296px;
  height: 96px;
  top: 50px;
}

The rotate values can all remain the same as the cube example, but for this rectangular prism, the translate values do differ. The front and back faces are each shifted out 50 pixels since the #box is 100 pixels deep. The translate value for the left and right faces is 150 pixels for their 300 pixels width. Top and bottom panels take 100 pixels for their 200 pixels height:

#box .front { -webkit-transform: rotateY(0deg) translateZ(50px); }
#box .back { -webkit-transform: rotateX(180deg) translateZ(50px); }
#box .right { -webkit-transform: rotateY(90deg) translateZ(150px); }
#box .left { -webkit-transform: rotateY(-90deg) translateZ(150px); }
#box .top { -webkit-transform: rotateX(90deg) translateZ(100px); }
#box .bottom { -webkit-transform: rotateX(-90deg) translateZ(100px); }

See Example: Box 1.







Just like the cube example, to expose a face, the #box needs to have a style to reverse that face’s transform. Both the translateZ and rotate values are the opposites of the corresponding face.

#box.show-front { -webkit-transform: translateZ(-50px) rotateY(0deg); }
#box.show-back { -webkit-transform: translateZ(-50px) rotateX(-180deg); }
#box.show-right { -webkit-transform: translateZ(-150px) rotateY(-90deg); }
#box.show-left { -webkit-transform: translateZ(-150px) rotateY(90deg); }
#box.show-top { -webkit-transform: translateZ(-100px) rotateX(-90deg); }
#box.show-bottom { -webkit-transform: translateZ(-100px) rotateX(90deg); }

See Example: Box 2.



Rotating the rectangular box with a CSS transition



Carousel

Front-end developers have a myriad of choices when it comes to content carousels. Now that we have 3-D capabilities in our browsers, why not take a shot at creating an actual 3-D carousel?

The markup for this demo takes the same form as the box, cube and card. Let’s make it interesting and have a carousel with nine panels.

<div class=""container"">
  <div id=""carousel"">
    <figure>1</figure>
    <figure>2</figure>
    <figure>3</figure>
    <figure>4</figure>
    <figure>5</figure>
    <figure>6</figure>
    <figure>7</figure>
    <figure>8</figure>
    <figure>9</figure>
  </div>
</div>

Now, apply basic layout styles. Let’s give each panel of the #carousel 20 pixel gaps between one another, done here with left: 10px; and top: 10px;. The effective width of each panel is 210 pixels.

.container {
  width: 210px;
  height: 140px;
  position: relative;
  -webkit-perspective: 1000;
}
#carousel {
  width: 100%;
  height: 100%;
  position: absolute;
  -webkit-transform-style: preserve-3d;
}
#carousel figure {
  display: block;
  position: absolute;
  width: 186px;
  height: 116px;
  left: 10px;
  top: 10px;
  border: 2px solid black;
}

Next up: rotating the faces. This #carousel has nine panels. If each panel gets an equal distribution on the carousel, each panel would be rotated forty degrees from its neighbour (360 ÷ 9).

#carousel figure:nth-child(1) { -webkit-transform: rotateY(0deg); }
#carousel figure:nth-child(2) { -webkit-transform: rotateY(40deg); }
#carousel figure:nth-child(3) { -webkit-transform: rotateY(80deg); }
#carousel figure:nth-child(4) { -webkit-transform: rotateY(120deg); }
#carousel figure:nth-child(5) { -webkit-transform: rotateY(160deg); }
#carousel figure:nth-child(6) { -webkit-transform: rotateY(200deg); }
#carousel figure:nth-child(7) { -webkit-transform: rotateY(240deg); }
#carousel figure:nth-child(8) { -webkit-transform: rotateY(280deg); }
#carousel figure:nth-child(9) { -webkit-transform: rotateY(320deg); }

Now, the outward shift. Back when we were creating the cube and box, the translate value was simple to calculate, as it was equal to one half the width, height or depth of the object. With this carousel, there is no size we can automatically use as a reference. We’ll have to calculate the distance of the shift by other means.



Drawing a diagram of the carousel, we can see that we know only two things: the width of each panel is 210 pixels; and the each panel is rotated forty degrees from the next. If we split one of these segments down its centre, we get a right-angled triangle, perfect for some trigonometry.

We can determine the length of r in this diagram with a basic tangent equation:



There you have it: the panels need to be translated 288 pixels in 3-D space. 

#carousel figure:nth-child(1) { -webkit-transform: rotateY(0deg) translateZ(288px); }
#carousel figure:nth-child(2) { -webkit-transform: rotateY(40deg) translateZ(288px); }
#carousel figure:nth-child(3) { -webkit-transform: rotateY(80deg) translateZ(288px); }
#carousel figure:nth-child(4) { -webkit-transform: rotateY(120deg) translateZ(288px); }
#carousel figure:nth-child(5) { -webkit-transform: rotateY(160deg) translateZ(288px); }
#carousel figure:nth-child(6) { -webkit-transform: rotateY(200deg) translateZ(288px); }
#carousel figure:nth-child(7) { -webkit-transform: rotateY(240deg) translateZ(288px); }
#carousel figure:nth-child(8) { -webkit-transform: rotateY(280deg) translateZ(288px); }
#carousel figure:nth-child(9) { -webkit-transform: rotateY(320deg) translateZ(288px); }

If we decide to change the width of the panel or the number of panels, we only need to plug in those two variables into our equation to get the appropriate translateZ value. In JavaScript terms, that equation would be:

var tz = Math.round( ( panelSize / 2 ) / 
  Math.tan( ( ( Math.PI * 2 ) / numberOfPanels ) / 2 ) );
// or simplified to
var tz = Math.round( ( panelSize / 2 ) / 
  Math.tan( Math.PI / numberOfPanels ) );

Just like our previous 3-D objects, to show any one panel we need only apply the reverse transform on the carousel. Here’s the style to show the fifth panel:

-webkit-transform: translateZ(-288px) rotateY(-160deg);

See Example: Carousel 1.







By now, you probably have two thoughts: 


	Rewriting transform styles for each panel looks tedious.
	Why bother doing high school maths? Aren’t robots supposed to be doing all this work for us?


And you’re absolutely right. The repetitive nature of 3-D objects lends itself to scripting. We can offload all the monotonous transform styles to our dynamic script, which, if done correctly, will be more flexible than the hard-coded version.

See Example: Carousel 2.

Conclusion

3-D transforms change the way we think about the blank canvas of web design. Better yet, they change the canvas itself, trading in the flat surface for voluminous depth.

My hope is that you took at least one peak at a demo and were intrigued. We web designers, who have rejoiced for border-radius, box-shadow and background gradients, now have an incredible tool at our disposal in 3-D transforms. They deserve just the same enthusiasm, research and experimentation we have seen on other CSS3 features. Now is the perfect time to take the plunge and start thinking about how to use three dimensions to elevate our craft. I’m breathless waiting for what’s to come.

233,Wrapping Things Nicely with HTML5 Local Storage,"HTML5 is here to turn the web from a web of hacks into a web of applications – and we are well on the way to this goal. The coming year will be totally and utterly awesome if you are excited about web technologies.

This year the HTML5 revolution started and there is no stopping it. For the first time all the browser vendors are rallying together to make a technology work. The new browser war is fought over implementation of the HTML5 standard and not over random additions. We live in exciting times.

Starting with a bang

As with every revolution there is a lot of noise with bangs and explosions, and that’s the stage we’re at right now. HTML5 showcases are often CSS3 showcases, web font playgrounds, or video and canvas examples.

This is great, as it gets people excited and it gives the media something to show. There is much more to HTML5, though. Let’s take a look at one of the less sexy, but amazingly useful features of HTML5 (it was in the HTML5 specs, but grew at such an alarming rate that it warranted its own spec): storing information on the client-side.

Why store data on the client-side?

Storing information in people’s browsers affords us a few options that every application should have:


	You can retain the state of an application – when the user comes back after closing the browser, everything will be as she left it. That’s how ‘real’ applications work and this is how the web ones should, too.
	You can cache data – if something doesn’t change then there is no point in loading it over the Internet if local access is so much faster
	You can store user preferences – without needing to keep that data on your server at all.


In the past, storing local data wasn’t much fun.

The pain of hacky browser solutions

In the past, all we had were cookies. I don’t mean the yummy things you get with your coffee, endorsed by the blue, furry junkie in Sesame Street, but the other, digital ones. Cookies suck – it isn’t fun to have an unencrypted HTTP overhead on every server request for storing four kilobytes of data in a cryptic format. It was OK for 1994, but really neither an easy nor a beautiful solution for the task of storing data on the client.

Then came a plethora of solutions by different vendors – from Microsoft’s userdata to Flash’s LSO, and from Silverlight isolated storage to Google’s Gears. If you want to know just how many crazy and convoluted ways there are to store a bit of information, check out Samy’s evercookie.

Clearly, we needed an easier and standardised way of storing local data.

Keeping it simple – local storage

And, lo and behold, we have one. The local storage API (or session storage, with the only difference being that session data is lost when the window is closed) is ridiculously easy to use. All you do is call a few methods on the window.localStorage object – or even just set the properties directly using the square bracket notation:

if('localStorage' in window && window['localStorage'] !== null){
	var store = window.localStorage;

	// valid, API way
		store.setItem(‘cow’,‘moo’);
		console.log(
		store.getItem(‘cow’)
	); // => ‘moo’

	// shorthand, breaks at keys with spaces
		store.sheep = ‘baa’ 
		console.log(
		store.sheep 
	); // ‘baa’

	// shorthand for all
		store[‘dog’] = ‘bark’
		console.log(
		store[‘dog’]
	); // => ‘bark’

}

Browser support is actually pretty good: Chrome 4+; Firefox 3.5+; IE8+; Opera 10.5+; Safari 4+; plus iPhone 2.0+; and Android 2.0+. That should cover most of your needs. Of course, you should check for support first (or use a wrapper library like YUI Storage Utility or YUI Storage Lite).

The data is stored on a per domain basis and you can store up to five megabytes of data in localStorage for each domain.

Strings attached

By default, localStorage only supports strings as storage formats. You can’t store results of JavaScript computations that are arrays or objects, and every number is stored as a string. This means that long, floating point numbers eat into the available memory much more quickly than if they were stored as numbers.

var cowdesc = ""the cow is of the bovine ilk, ""+
		""one end is for the moo, the ""+
		""other for the milk"";

var cowdef = {
	ilk“bovine”,
	legs,
	udders,
	purposes
		front“moo”,
		end“milk”
	}
};

window.localStorage.setItem(‘describecow’,cowdesc);
console.log(
	window.localStorage.getItem(‘describecow’)
); // => the cow is of the bovine… 

window.localStorage.setItem(‘definecow’,cowdef);
console.log(
	window.localStorage.getItem(‘definecow’)
); // => [object Object] = bad!

This limits what you can store quite heavily, which is why it makes sense to use JSON to encode and decode the data you store:

var cowdef = {
	""ilk"":""bovine"",
	""legs"":4,
	""udders"":4,
	""purposes"":{
	""front"":""moo"",
	""end"":""milk""
	}
};

window.localStorage.setItem(‘describecow’,JSON.stringify(cowdef));
console.log(
	JSON.parse(
		window.localStorage.getItem(‘describecow’)
	)
); // =>  Object { ilk=“bovine”,  more…}

You can also come up with your own formatting solutions like CSV, or pipe | or tilde ~ separated formats, but JSON is very terse and has native browser support.

Some use case examples

The simplest use of localStorage is, of course, storing some data: the current state of a game; how far through a multi-form sign-up process a user is; and other things we traditionally stored in cookies. Using JSON, though, we can do cooler things.

Speeding up web service use and avoiding exceeding the quota

A lot of web services only allow you a certain amount of hits per hour or day, and can be very slow. By using localStorage with a time stamp, you can cache results of web services locally and only access them after a certain time to refresh the data.

I used this technique in my An Event Apart 10K entry, World Info, to only load the massive dataset of all the world information once, and allow for much faster subsequent visits to the site. The following screencast shows the difference:



For use with YQL (remember last year’s 24 ways entry?), I’ve built a small script called YQL localcache that wraps localStorage around the YQL data call. An example would be the following:

yqlcache.get({
	yql: 'select * from flickr.photos.search where text=""santa""',
	id: 'myphotos',
	cacheage: ( 60*60*1000 ),
	callback: function(data) {
		console.log(data);
	}
});

This loads photos of Santa from Flickr and stores them for an hour in the key myphotos of localStorage. If you call the function at various times, you receive an object back with the YQL results in a data property and a type property which defines where the data came from – live is live data, cached means it comes from cache, and freshcache indicates that it was called for the first time and a new cache was primed. The cache will work for an hour (60×60×1,000 milliseconds) and then be refreshed. So, instead of hitting the YQL endpoint over and over again, you hit it once per hour.

Caching a full interface

Another use case I found was to retain the state of a whole interface of an application by caching the innerHTML once it has been rendered. I use this in the Yahoo Firehose search interface, and you can get the full story about local storage and how it is used in this screencast:



The stripped down code is incredibly simple (JavaScript with PHP embed):

// test for localStorage support
if(('localStorage' in window) && window['localStorage'] !== null){

var f = document.getElementById(‘mainform’);
// test with PHP if the form was sent (the submit button has the name “sent”)


	// get the HTML of the form and cache it in the property “state”
	localStorage.setItem(‘state’,f.innerHTML);

// if the form hasn’t been sent…


	// check if a state property exists and write back the HTML cache
	if(‘state’ in localStorage){
		f.innerHTML = localStorage.getItem(‘state’);  
	}

	

}

Other ideas

In essence, you can use local storage every time you need to speed up access. For example, you could store image sprites in base-64 encoded datasets instead of loading them from a server. Or you could store CSS and JavaScript libraries on the client. Anything goes – have a play.

Issues with local and session storage

Of course, not all is rainbows and unicorns with the localStorage API. There are a few niggles that need ironing out. As with anything, this needs people to use the technology and raise issues. Here are some of the problems:


	Inadequate information about storage quota – if you try to add more content to an already full store, you get a QUOTA_EXCEEDED_ERR and that’s it. There’s a great explanation and test suite for localStorage quota available.
	Lack of automatically expiring storage – a feature that cookies came with. Pamela Fox has a solution (also available as a demo and source code)
	Lack of encrypted storage – right now, everything is stored in readable strings in the browser.


Bigger, better, faster, more!

As cool as the local and session storage APIs are, they are not quite ready for extensive adoption – the storage limits might get in your way, and if you really want to go to town with accessing, filtering and sorting data, real databases are what you’ll need. And, as we live in a world of client-side development, people are moving from heavy server-side databases like MySQL to NoSQL environments.

On the web, there is also a lot of work going on, with Ian Hickson of Google proposing the Web SQL database, and Nikunj Mehta, Jonas Sicking (Mozilla), Eliot Graff (Microsoft) and Andrei Popescu (Google) taking the idea beyond simply replicating MySQL and instead offering Indexed DB as an even faster alternative.

On the mobile front, a really important feature is to be able to store data to use when you are offline (mobile coverage and roaming data plans anybody?) and you can use the Offline Webapps API for that.

As I mentioned at the beginning, we have a very exciting time ahead – let’s make this web work faster and more reliably by using what browsers offer us. For more on local storage, check out the chapter on Dive into HTML5.",2010,Christian Heilmann,chrisheilmann,2010-12-06T00:00:00+00:00,https://24ways.org/2010/html5-local-storage/,code
225,Good Ideas Grow on Paper,"Great designers have one thing in common: their design process is centred on ideas; ideas that are more often than not developed on paper. Though it’s often tempting to take the path of least resistance, turning to the computer in the headlong rush to complete a project (often in the face of formidable client pressure), resist the urge and – for a truly great idea – start first on paper.

The path of least resistance is often characterised by cliché and overused techniques – one per cent noise, border-radius, text-shadow – the usual suspects – techniques that are ten-a-penny at the gallery sites. Whilst all are useful, and technique and craft are important, great design isn’t about technique alone – it’s about technique in the service of good ideas.

But how do we generate those ideas?

Inspiration can certainly come to you out of the blue. When working as a designer in a role which often consists of incubating good ideas, however, idly waiting for the time-honoured lightbulb to appear above your head just isn’t good enough. We need to establish an environment where we tip the odds of getting good ideas in our favour.

So, when faced with the blank canvas, what do we do to unlock the proverbial tidal wave of creativity? Fear not. We’re about to share with you a couple of stalwart techniques that will stand you in good stead when you need that good idea, in the face of the pressure of yet another looming deadline.

Get the process right

Where do ideas come from? In many cases they come from anywhere but the screen. Hence, our first commandment is to close the lid of your computer and, for a change, work on paper. It might seem strange, it might also seem like a distraction, but – trust us – the time invested here will more than pay off.

Idea generation should be a process of rapid iteration, sketching and thinking aloud, all processes best undertaken in more fast paced, analogue media. Our tool of choice is the Sharpie and Flip Chart Combo©, intentionally low resolution to encourage lo-fi idea generation. In short, your tools should be designed not to be precious, but to quickly process your thoughts. Ideas can be expressed with a thick line marker or by drawing with a stick in the sand; it’s the ideas that matter, not the medium.

Input > Synthesise > Output

Ideas don’t materialise in a vacuum. Without constant input, the outputs will inevitably remain the same. As such, it’s essential to maintain an inquisitive mind, ensuring a steady flow of new triggers and stimuli that enable your thinking to evolve.

What every designer brings to the table is their prior experience and unique knowledge. It should come as no surprise to discover that a tried and tested method of increasing that knowledge is, believe it or not, to read – often and widely. The best and most nuanced ideas come after many years of priming the brain with an array of diverse material, a point made recently in Jessica Hische’s aptly named Why You Should Know Your Shit.

One of the best ways of synthesising the knowledge you accumulate is to write. The act of writing facilitates your thinking and stores the pieces of the jigsaw you’ll one day return to. You don’t have to write a book or a well-articulated article; a scribbled note in the margin will suffice in facilitating the process of digestion.

As with writing, we implore you to make sketching an essential part of your digestion process. More immediate than writing, sketching has the power to put yet unformed ideas down on paper, giving you an insight into the fantastic conceptions you’re more often than not still incubating.

Our second commandment is a practical one: always carry a sketchbook and a pen. Although it seems that the very best ideas are scribbled on the back of a beer mat or a wine-stained napkin, always carrying your ‘thinking utensils’ should be as natural as not leaving the house without your phone, wallet, keys or pants.

Further, the more you use your sketchbook, the less precious you’ll find yourself becoming. Sketching isn’t about being an excellent draughtsman, it’s about synthesising and processing your thoughts and ideas, as Jason Santa Maria summarises nicely in his article Pretty Sketchy:


	Sketchbooks are not about being a good artist, they’re about being a good thinker.

	Jason Santa Maria


The sketchbook and pen should become your trusted tools in your task to constantly survey the world around you. As Paul Smith says, You Can Find Inspiration in Anything; close the lid, look beyond the computer; there’s a whole world of inspiration out there.

Learn to love old dusty buildings

So, how do you learn? How do you push beyond the predictable world pre-filtered by Mr Google? The answer lies in establishing a habit of exploring the wonderful worlds of museums and libraries, dusty old buildings that repay repeated visits.

Once the primary repositories of thought and endless sources of inspiration, these institutions are now often passed over for the quick fix of a Google search or Wikipedia by you, the designer, chained to a desk and manacled to a MacBook. Whilst others might frown, we urge you to get away from your desk and take an eye-opening stroll through the knowledge-filled corridors of yore (and don’t forget to bring your sketchbook).

Here you’ll find ideas aplenty, ideas that will set you apart from your peers, who remain ever-reliant on the same old digital sources.

The idea generation toolbox

Now that we’ve established the importance of getting the process and the context right, it’s time to meet the idea generation toolbox: a series of tools and techniques that can be applied singularly or in combination to solve the perennial problem of the blank canvas.

The clean sheet of paper, numbing in its emptiness, can prove an insurmountable barrier to many a project, but the route beyond it involves just a few, well-considered steps. The route to a good idea lies in widening your pool of inspiration at the project outset. Let go and generate ideas quickly; it’s critical to diverge before you converge – but how do we do this and what exactly do we mean by this?

The temptation is to pull something out of your well-worn box of tricks, something that you know from experience will do the job. We urge you, however, not to fall prey to this desire. You can do better; better still, a few of you putting your minds together can do a lot better. By avoiding the path of least resistance, you can create something extraordinary.

Culturally, we value logical, linear thinking. Since the days of Plato and Aristotle, critical thinking, deduction and the pursuit of truth have been rewarded. To generate creative ideas, however, we need to start thinking sideways, making connections that don’t necessarily follow logically. Lateral thinking, a phrase coined by Edward de Bono in 1967, aptly describes this very process:


	With logic you start out with certain ingredients, just as in playing chess you start out with given pieces – lateral thinking is concerned not with playing with the existing pieces but with seeking to change those very pieces.

	Edward de Bono


One of the easiest ways to start thinking laterally is to start with a mind map, a perfect tool for widening the scope of a project beyond the predictable and an ideal one for getting the context right for discovery.

Making connections

Mind maps can be used to generate, visualise and structure ideas. Arranged intuitively and classified around groupings, mind maps allow chance connections to be drawn across related groups of information, and are perfect for exposing alogical associations and unexpected relationships.

Get a number of people together in a room, equipped with the Sharpie and Flip Chart Combo©. Give yourself a limited amount of time – half an hour should prove more than enough – and you’ll be surprised at the results a few well-chosen people can generate in a very short space of time. The key is to work fast, diverge and not inhibit thinking. 

We’ve been embracing Tony Buzan’s methods in our teaching for over a decade. His ideas on the power of radiant thinking and how this can be applied to mind maps, uncover the real power which lies in the human brain’s ability to spot connections across a mapped out body of diverse knowledge.

Frank Chimero wrote about this recently in How to Have an Idea, which beautifully illustrates Mr Buzan’s theories, articulating the importance of the brain’s ability to make abstract connections, finding unexpected pairings when a concept is mapped out on paper.

Once a topic is surveyed and a rich set of stimuli articulated, the next stage is to draw connections, pulling from opposite sides of the mind map. It’s at this point, when defining alogical connections, that the truly interesting and unexpected ideas are often uncovered.

The curve ball

If you’ve followed our instructions so far, all being well, you should have a number of ideas. Good news: we have one last technique to throw into the mix. We like to call it ‘the curve ball’, that last minute ‘something’ that forces you to rethink and encourages you to address a problem from a different direction.

There are a number of ways of throwing in a curve ball – a short, sharp, unexpected impetus – but we have a firm favourite we think you’ll appreciate. Brian Eno and Peter Schmidt’s Oblique Strategies – subtitled ‘Over One Hundred Worthwhile Dilemmas’ – are the perfect creative tool for throwing in a spot of unpredictability. As Eno and Schmidt put it:


	The Oblique Strategies can be used as a pack (a set of possibilities being continuously reviewed in the mind) or by drawing a single card from the shuffled pack when a dilemma occurs in a working situation. In this case the card is trusted even if its appropriateness is quite unclear. They are not final, as new ideas will present themselves, and others will become self-evident.

	Brian Eno and Peter Schmidt


Simply pick a card and apply the strategy to the problem at hand. The key here, as with de Bono’s techniques, is to embrace randomness and provocation to inspire lateral creative approaches.

To assist this process, you might wish to consult one of the many virtual decks of Oblique Strategies online.

Wrapping up

To summarise, it’s tempting to see the route to the fastest satisfactory conclusion in a computer when, in reality, that’s the last place you should start. The tools we’ve introduced, far from time-consuming, are hyper-efficient, always at hand and, if you factor them into your workflow, the key to unlocking the ideas that set the great designers apart.

We wish you well on your quest in search of the perfect idea, now armed with the knowledge that the quest begins on paper.",2010,The Standardistas,thestandardistas,2010-12-13T00:00:00+00:00,https://24ways.org/2010/good-ideas-grow-on-paper/,process
222,Golden Spirals,"As building blocks go, the rectangle is not one to overwhelm the designer with decisions. On the face of it, you have two options: you can set the width, and the height. But despite this apparent simplicity, there are combinations of width and height that can look unbalanced. If a rectangle is too tall and slim, it might appear precarious. If it is not tall enough, it may simply look flat. But like a guitar string that’s out of tune, you can tweak the proportions little by little until a rectangle feels, as Goldilocks said, just right.

A golden rectangle has its height and width in the golden ratio, which is approximately 1:1.618. These proportions have long been recognised as being aesthetically harmonious. Whether through instruction or by intuition, artists have understood how to exploit these proportions over the centuries. Examples can be found in classical architecture, medieval book construction, and even in the recent #newtwitter redesign.

A mathematical curiosity







The golden rectangle is unique, in that if you remove a square section from it, what is left behind is itself a golden rectangle. The removal of a square can be repeated on the rectangle that is left behind, and then repeated again, as many times as you like. This means that the golden rectangle can be treated as a building block for recursive patterns. In this article, we will exploit this property to build a golden spiral, using only HTML and CSS.

The markup

The HTML we’ll use for this study is simply a series of nested <div>s.

<body>
	<div id=""container"">
		<div class=""cycle"">
			<div>
				<div>
					<div>
						<div class=""cycle"">
							<div>
								<div>
									<div>
										<div class=""cycle"">
											<div>
												<div>
													<div>
														<div class=""cycle""></div>
													</div>
												</div>
											</div>
										</div>
									</div>
								</div>
							</div>
						</div>
					</div>
				</div>
			</div>
		</div>
	</div>
</body>

The first of these has the class cycle, and so does every fourth ancestor thereafter. The spiral completes a cycle every four steps, so this class allows styles to be reused on <div>s that appear at the same position in each cycle.

Golden proportions

To create our spiral we are going to exploit the unique properties of the golden rectangle, so our first priority is to ensure that we have a golden rectangle to begin with. If we pick a length for the short edge – say, 288 pixels – we can then calculate the length of the long edge by multiplying this value by 1.618. In this case, 288 × 1.618 = 466, so our starting point will be a <div> with these properties:

#container > div {
  width: 466px;
  height: 288px;
}

The greater than symbol is used here to single out the immediate child of the #container element, without affecting the grandchild or any of the more distant descendants.

We could go on to specify the precise pixel dimensions of every child element, but that means doing a lot of sums. It would be much easier if we just specified the dimensions for each element as a percentage of the width and height of its parent. This also has the advantage that if you change the size of the outermost container, all nested elements would be resized automatically – something that we shall exploit later.







The approximate value of 38.2% can be derived from (100 × 1 − phi) ÷ phi, where the Greek letter phi (ϕ) stands for the golden ratio. The value of phi can be expressed as phi = (1 + √5 ) ÷ 2, which is approximately 1.618. You don’t have to understand the derivation to use it. Just remember that if you start with a golden rectangle, you can slice 38.2% from it to create a new golden rectangle.

This can be expressed in CSS quite simply:

.cycle,
.cycle > div > div {
  height: 38.2%;
  width: 100%;
}
.cycle > div,
.cycle > div > div > div {
  width: 38.2%;
  height: 100%;
}

You can see the result so far by visiting Demo One. With no borders or shading, there is nothing to see yet, so let’s address that next.

Shading with transparency

We’ll need to apply some shading to distinguish each segment of the spiral from its neighbours. We could start with a white background, then progress through shades of grey: #eee, #ddd, #ccc and so on, but this means hard-coding the background-color for every element. A more elegant solution would be to use the same colour for every element, but to make each one slightly transparent.

The nested <div>s that we are working with could be compared to layers in Photoshop. By applying a semi-transparent shade of grey, each successive layer can build on top of the darker layers beneath it. The effect accumulates, causing each successive layer to appear slightly darker than the last. In his 2009 article for 24 ways, Drew McLellan showed how to create a semi-transparent effect by working with RGBA colour. Here, we’ll use the colour black with an alpha value of 0.07.

#container div { background-color: rgba(0,0,0,0.07) }

Note that I haven’t used the immediate child selector here, which means that this rule will apply to all <div> elements inside the #container, no matter how deeply nested they are. You can view the result in Demo Two. As you can see, the golden rectangles alternate between landscape and portrait orientation.



Demo Three).



CSS3 specification indicates that a percentage can be used to set the border-radius property, but using percentages does not achieve consistent results in browsers today. Luckily, if you specify a border-radius in pixels using a value that is greater than the width and height of the element, then the resulting curve will use the shorter length side as its radius. This produces exactly the effect that we want, so we’ll use an arbitrarily high value of 10,000 pixels for each border-radius:

.cycle {
  border-radius: 0px;
  border-bottom-left-radius: 10000px;
}
.cycle > div {
  border-radius: 0px;
  border-bottom-right-radius: 10000px;
}
.cycle > div > div {
  border-radius: 0px;
  border-top-right-radius: 10000px;
}
.cycle > div > div > div {
  border-radius: 0px;
  border-top-left-radius: 10000px;
}

Note that the specification for the border-radius property is still in flux, so it is advisable to use vendor-specific prefixes. I have omitted them from the example above for the sake of clarity, but if you view source on Demo Four then you’ll see that the actual styles are not quite as brief.







Filling the available space

We have created an approximation of the Golden Spiral using only HTML and CSS. Neat! It’s a shame that it occupies just a fraction of the available space. As a finishing touch, let’s make the golden spiral expand or contract to use the full space available to it.

Ideally, the outermost container should use the full available width or height that could accomodate a rectangle of golden proportions. This behaviour is available for background images using the “ background-size: contain; property, but I know of no way to make block level HTML elements behave in this fashion (if I’m missing something, please enlighten me). Where CSS fails to deliver, JavaScript can usually provide a workaround. This snippet requires jQuery:

$(document).ready(function() {
	var phi = (1 + Math.sqrt(5))/2;

	$(window).resize(function() {
		var goldenWidth  = windowWidth  = $(this).width(),
			goldenHeight = windowHeight = $(this).height();

		if (windowWidth/windowHeight > phi) {
			// panoramic viewport – use full height
			goldenWidth  = windowHeight * phi;
		} else {
			// portrait viewport  – use full width
			goldenHeight = windowWidth / phi;
		};

	$(""#container > div.cycle"")
		.width(goldenWidth)
		.height(goldenHeight);

	}).resize();

});

You can view the result by visiting Demo Five.







Is it just me, or can you see an elephant in there?

You can probably think of many ways to enhance this further, but for this study we’ll leave it there. It has been a good excuse to play with proportions, positioning and the immediate child selector, as well as new CSS3 features such as border-radius and RGBA colours. If you are not already designing with golden proportions, then perhaps this will inspire you to begin.",2010,Drew Neil,drewneil,2010-12-07T00:00:00+00:00,https://24ways.org/2010/golden-spirals/,design
224,Go Forth and Make Awesomeness,"We’ve all dreamed of being a superhero: maybe that’s why we’ve ended up on the web—a place where we can do good deeds and celebrate them on a daily basis. 

Wear your dreams

At age four, I wore my Wonder Woman Underoos around my house, my grandparents’ house, our neighbor’s house, and even around the yard. I wanted to be a superhero when I grew up. I was crushed to learn that there is no school for superheroes—no place to earn a degree in how to save the world from looming evil. Instead, I—like everyone else—was destined to go to ordinary school to focus on ABCs and 123s. Even still, I want to save the world.

Intend your goodness

Random acts of kindness make a difference. Books, films, and advertising campaigns tout random acts of kindness and the positive influence they can have on the world. But why do acts of kindness have to be so random? Why can’t we intend to be kind? A true superhero wakes each morning intending to perform selfless acts for the community. Why can’t we do the same thing?

As a child, my mother taught me to plan to do at least three good deeds each day. And even now, years later, I put on my invisible cape looking for ways to do good.

Here are some examples:

	slowing down to allow another driver in before me from the highway on-ramp
	bringing a co-worker their favorite kind of coffee or tea
	sharing my umbrella on a rainy day
	holding a door open for someone with full hands
	listening intently when someone shares a story
	complimenting someone on a job well done
	thanking someone for a job well done
	leaving a constructive, or even supportive comment on someone’s blog


As you can see, these acts are simple. Doing good and being kind is partially about being aware—aware of the words we speak and the actions we take. Like superheroes, we create our own code of conduct to live by. Hopefully, we choose to put the community before ourselves (within reason) and to do our best not to damage it as we move through our lives.

Take a bite out of the Apple

With some thought, we can weave this type of thinking and action into our business choices. We can take the simple acts of kindness concept and amplify it a bit. With this amplification, we can be a new kind of superhero.

In 1997, during a presentation, Steve Jobs stated Apple’s core value in a simple, yet powerful, sentence:


	We believe that people with passion can change the world for the better.


Apple fan or not, those are powerful words.

Define your core

Every organization must define its core values. Core values help us to frame, recognize, and understand the principles our organization embodies and practices. It doesn’t matter if you’re starting a new organization or you want to define values within an existing organization. Even if you’re a freelancer, defining core values will help guide your decisions and actions.

If you can, work as a team to define core values. Gather the people who are your support system—your business partners, your colleagues, and maybe even a trusted client—this is now your core value creation team. Have a brainstorming session with your team. Let ideas flow. Give equal weight to the things people say. You may not hear everything you thought you might hear—that’s OK. You want the session to be free-flowing and honest. Ask yourself and your team questions like:


	What do you think my/our/your core values are?
	What do you think my/our/your priorities are?
	What do you think my/our/your core values should be?
	What do you think my/our/your priorities should be?
	How do you think I/we should treat customers, clients, and each other?
	How do we want others to treat us?
	What are my/our/your success stories?
	What has defined these experiences as successful?


From this brainstorming session, you will craft your superhero code of conduct. You will decide what you will and will not do. You will determine how you will and will not act. You’re setting the standards that you will live and work by—so don’t take this exercise lightly. Take your time. Use the exercise as a way to open a discussion about values. Find out what you and your team believe in. Set these values and keep them in place. Write them down and share these with your team and with the world. By sharing your core values, you hold yourself more accountable to them. You also send a strong message to the rest of the world about what type of organization you are and what you believe in. Other organizations and people may decide to align or not to align themselves with you because of your core values. This is good. Chances are, you’ll be happier and more profitable if you work with other organizations and people who share similar core values.

During your brainstorming session, list keywords. Don’t edit. Allow things to take their course. Some examples of keywords might be:

Ability · Achievement · Adventure · Ambition · Altruism · Awareness · Balance · Caring · Charity · Citizenship · Collaboration · Commitment · Community · Compassion · Consideration · Cooperation · Courage · Courtesy · Creativity · Democracy · Dignity · Diplomacy · Discipline · Diversity · Education · Efficiency · Energy · Equality · Excellence · Excitement · Fairness · Family · Freedom · Fun · Goodness · Gratefulness · Growth · Happiness · Harmony · Helping · Honor · Hope · Humility · Humor · Imagination · Individuality · Innovation · Integrity · Intelligence · Joy · Justice · Kindness · Knowledge · Leadership · Learning · Loyalty · Meaning · Mindfulness · Moderation · Modesty · Nurture · Openness · Organization · Passion · Patience · Peace · Planning · Principles · Productivity · Purpose · Quality · Reliability · Respectfulness · Responsibility · Security · Sensitivity · Service · Sharing · Simplicity · Stability · Tolerance · Transparency · Trust · Truthfulness · Understanding · Unity · Variety · Vision · Wisdom

After you have a list of keywords, create your core values statement using the themes from your brainstorming session. There are no rules: while above, Steve Jobs summed up Apple’s core values in one sentence, Zappos has ten core values:


	Deliver WOW Through Service
	Embrace and Drive Change
	Create Fun and A Little Weirdness
	Be Adventurous, Creative, and Open-Minded
	Pursue Growth and Learning
	Build Open and Honest Relationships With Communication
	Build a Positive Team and Family Spirit
	Do More With Less
	Be Passionate and Determined
	Be Humble


To see how Zappos’ employees embrace these core values, watch the video they created and posted on their website.

Dog food is yummy

Although I find merit in every keyword listed, I’ve distilled my core values to their simplest form:

Make awesomeness. Do good.

How do you make awesomeness and do good? You need ambition, balance, collaboration, commitment, fun, and you need every keyword listed to support these actions. Again, there are no rules: your core values can be one sentence or a bulleted list. What matters is being true to yourself and creating core values that others can understand.  Before I start any project I ask myself: is there a way to make awesomeness and to do good? If the answer is “yes,” I embrace the endeavor because it aligns with my core values. If the answer is “no,” I move on to a project that supports my core values.

Unleash your powers

Although every organization will craft different core values, I imagine that you want to be a superhero and that you will define “doing good” (or something similar) as one of your core values. Whether you work by yourself or with a team, you can use the web as a tool to help do good. It can be as simple as giving a free hug, or something a little more complex to help others and help your organization meet the bottom line. Some interesting initiatives that use the web to do good are:


	Yahoo!: How Good Grows
	Desigual: Happy Hunters
	Edge Shave Gel: Anti-irritation campaign




Knowing your underlying desire to return to your Underoos-and-cape-sporting childhood and knowing that you don’t always have the opportunity to develop an entire initiative to “do good,” remember that as writers, designers, and developers, we can perform superhero acts on a daily basis by making content, design, and development accessible to the greatest number of people. By considering other people’s needs, we are intentionally performing acts of kindness—we’re doing good. There are many ways to write, design, and develop websites—many of which will be discussed in other 24ways.org articles. As we make content, design, and development decisions—as we develop campaigns and initiatives—we need to keep our core values in mind. It’s easy to make a positive difference in the world. Just be the superhero you’ve always wanted to be. Go forth and make awesomeness.

220,Finding Your Way with Static Maps,"Since the introduction of the Google Maps service in 2005, online maps have taken off in a way not really possible before the invention of slippy map interaction. Although quickly followed by a plethora of similar services from both commercial and non-commercial parties, Google’s first-mover advantage, and easy-to-use developer API saw Google Maps become pretty much the de facto mapping service.



It’s now so easy to add a map to a web page, there’s no reason not to. Dropping an iframe map into your page is as simple as embedding a YouTube video.

But there’s one crucial drawback to both the solution Google provides for you to drop into your page and the code developers typically implement themselves – they don’t work without JavaScript.

A bit about JavaScript

Back in October of this year, The Yahoo! Developer Network blog ran some tests to measure how many visitors to the Yahoo! home page didn’t have JavaScript available or enabled in their browser. It’s an interesting test when you consider that the audience for the Yahoo! home page (one of the most visited pages on the web) represents about as mainstream a sample as you’ll find. If there’s any such thing as an ‘average Web user’ then this is them.

The results surprised me. It varied from region to region, but at most just two per cent of visitors didn’t have JavaScript running. To be honest, I was expecting it to be higher, but this quote from the article caught my attention:


	While the percentage of visitors with JavaScript disabled seems like a low number, keep in mind that small percentages of big numbers are also big numbers.


That’s right, of course, and it got me thinking about what that two per cent means. For many sites, two per cent is the number of visitors using the Opera web browser, using IE6, or using Mobile Safari. 

So, although a small percentage of the total, users without JavaScript can’t just be forgotten about, and catering for them is at the very heart of how the web is supposed to work.

Starting with content in HTML, we layer on presentation with CSS and then enhance interactivity with JavaScript. If anything fails along the way or the network craps out, or a browser just doesn’t support one of the technologies, the user still gets something they can work with. 

It’s progressive enhancement – also known as doing our jobs properly.

Sorry, wasn’t this about maps?

As I was saying, the default code Google provides, and the example code it gives to developers (which typically just gets followed ‘as is’) doesn’t account for users without JavaScript. No JavaScript, no content.

When adding the ability to publish maps to our small content management system Perch, I didn’t want to provide a solution that only worked with JavaScript. I had to go looking for a way to provide maps without JavaScript, too.

There’s a simple solution, fortunately, in the form of static map tiles. All the various slippy map services use a JavaScript interface on top of what are basically rendered map image tiles. Dragging the map loads in more image tiles in the direction you want to view. If you’ve used a slippy map on a slow connection, you’ll be familiar with seeing these tiles load in one by one.

The Static Map API

The good news is that these tiles (or tiles just like them) can be used as regular images on your site. Google has a Static Map API which not only gives you a handy interface to retrieve a tile for the exact area you need, but also allows you to place pins, and zoom and centre the tile so that the image looks just so. 

This means that you can create a static, non-JavaScript version of your slippy map’s initial (or ideal) state to load into your page as a regular image, and then have the JavaScript map hijack the image and make it slippy.

Clearly, that’s not going to be a perfect solution for every map’s requirements. It doesn’t allow for panning, zooming or interrogation without JavaScript. However, for the majority of straightforward map uses online, a static map makes a great alternative for those visitors without JavaScript.



Here’s the how

Retrieving a static map tile is staggeringly easy – it’s just a case of forming a URL with the correct arguments and then using that as the src of an image tag.

<img src=""http://maps.google.com/maps/api/staticmap
	?center=Bethlehem+Israel
	&zoom=5
	&size=540x280
	&maptype=satellite
	&markers=color:red|31.4211,35.1144
	&sensor=false"" 
	width=""540"" height=""280"" alt=""Map of Bethlehem, Israel"" />

As you can see, there are a few key options that we pass along to the base URL. All of these should be familiar to anyone who’s worked with the JavaScript API.


	center determines the point on which the map is centred. This can be latitude and longitude values, or simply an address which is then geocoded.
	zoom sets the zoom level.
	size is the pixel dimensions of the image you require.
	maptype can be roadmap, satellite, terrain or hybrid.
	markers sets one or more pin locations. Markers can be labelled, have different colours, and so on – there’s quite a lot of control available.
	sensor states whether you are using a sensor to determine the user’s location. When just embedding a map in a web page, set this to false.


There are many options, including plotting paths and setting the image format, which can all be found in the straightforward documentation.

Adding to your page

If you’ve worked with the JavaScript API, you’ll know that it needs a container element which you inject the map into:

<div id=""map""></div>

All you need to do is put your static image inside that container:

<div id=""map"">
   <img src=""http://maps.google.com/maps/api/staticmap[...]"" />
 </div>

And then, in your JavaScript, find the image and remove it. For example, with jQuery you’d simply use:

$('#map img').remove();

Why not use a <noscript> element around the image? You could, and that would certainly work fine for browsers that do not support JavaScript. What that won’t cover, however, is the situation where the browser has JavaScript support but, for whatever reason, the JavaScript doesn’t run. This could be due to network issues, an aggressive corporate firewall, or even just a bug in your code. So for that reason, we put the image in for all browsers that show images, and then remove it when the JavaScript is  successfully running.

The Google Static Map API limits the requests per site viewer – currently at one thousand distinct maps per day per viewer. So, for most sites you really don’t need to worry about the rate limit. Requests for the same tile aren’t normally counted, as the tile has already been generated and is cached. You can embed the images direct from Google and let it worry about the distribution and caching.

In conclusion

As you can see, adding a static map alongside your dynamic map for those users without JavaScript is very easy indeed. There may not be a huge percentage of web visitors browsing without JavaScript but, as we’ve seen, a small percentage of a big number is still a big number. When it’s so easy to add a static map, can you really justify not doing it?",2010,Drew McLellan,drewmclellan,2010-12-01T00:00:00+00:00,https://24ways.org/2010/finding-your-way-with-static-maps/,code
236,Extreme Design,"Recently, I set out with twelve other designers and developers for a 19th century fortress on the Channel Island of Alderney. We were going to /dev/fort, a sort of band camp for geeks. Our cohort’s mission: to think up, build and finish something – without readily available internet access.

Wait, no internet?

Well, pretty much. As the creators of /dev/fort James Aylett and Mark Norman Francis put it: “Imagine a place with no distractions – no IM, no Twitter”. But also no way to quickly look up a design pattern, code sample or source material. Like packing for camping, /dev/fort means bringing everything you’ll need on your back or your hard drive: from long johns to your favourite icon set.

We got to work the first night discussing ideas for what we wanted to build. By the time breakfast was cleared up the next morning, we’d settled on Russ’s idea to make the Apollo 13 (PDF) transcript accessible. Days two and three were spent collaboratively planning (KJ style) what features we wanted to build, and unravelling the larger UX challenges of the project. The next five days were spent building it. Within 36 hours of touchdown at Southampton Airport, we launched our creation: spacelog.org

The weather was cold, the coal fire less than ideal, food and supplies a hike away, and the process lightning-fast. A week of designing under extreme circumstances called for an extreme process. Some of this was driven by James’s and Norm’s experience running these things, but a lot of it materialised while we were there – especially for our three-strong design team (myself, Gavin O’ Carroll and Chris Govias) who, though we knew each other, had never worked together as a group in this kind of scenario before.

The outcome was a pretty spectacular process, with a some key takeaways useful for any small group trying to build something quickly.

What it’s like inside the fort

/dev/fort has the pressure and pace of a hack day without being a hack day – primarily, no workshops or interruptions‚ but also a different mentality. While hack days are typically developer-driven with a ‘hack first, design later (if at all)’ attitude, James was quick to tell the team to hold off from writing any code until we had a plan. This put a healthy pressure on the design and product folks to slash through the UX problems before we started building.

While the fort had definitely more of a hack day feel, all of us were familiar with Agile methods, so we borrowed a few useful techniques such as morning stand-ups and an emphasis on teamwork. We cut some really good features to make our launch date, and chunked the work based on user goals, iterating as we went.

What made this design process work?

A golden ratio of teams

My personal experience both professionally and in free-form situations like this, is a tendency to get/hire a designer. Leaders of businesses, founders of start-ups, organisers of events: one designer is not enough! Finding one ace-blooded designer who can ‘do everything’ will always result in bottleneck and burnout. Like the nuances between different development languages, design is a multifaceted discipline, and very few can claim to be equally strong in every aspect. Overlap in skill set will result in a stronger, more robust interface.

More importantly, however, having lots of designers to go around meant that we all had the opportunity to pair with developers, polishing the details that don’t usually get polished. As soon as we launched, the public reception of the design and UX was overwhelmingly positive (proof!). But also, a lot of people asked us who the designer was, attributing it to one person.

While it’s important to note that everyone in our team was multitalented (and could easily shift between roles, helping us all stay unblocked), the golden ratio James and Norm devised was two product/developer folks, three interaction designers and eight developers.

Equality inside the fortress walls

Something magical about the fort is how everyone leaves the outside world on the drawbridge. Job titles, professional status, Twitter followers, and so on. Like scout camp, a mutual respect and trust is expected of all the participants. Like extreme programming, extreme design requires us all to be equal partners in a collaborative team. I think this is especially worth noting for designers; our past is filled with the clear hierarchy of the traditional studio system which, however important for taste and style, seems less compatible with modern web/software development methods.

Being equal doesn’t mean being the same, however. We established clear roles and teams for ourselves on the second day, deferring to that person when a decision needed to be made. As the interface coalesced, the designers and developers took ownership over certain parts to ensure the details got looked after, while staying open to ideas and revisions from the rest of the cohort.

Create a space where everyone who enters is equal, but be sure to establish clear roles. Even if it’s just for a short while, the environment will be beneficial.

Hang your heraldry from the rafters

Forts and castles are full of lore: coats of arms; paintings of battles; suits of armour. It’s impossible not to be surrounded by these stories, words and ways of thinking. Like the whiteboards on the walls, putting organisational lore in your physical surroundings makes it impossible not to see.

Ryan Alexander brought some of those static-cling whiteboard sheets which were quickly filled with use cases; IA; team roles; and, most importantly, a glossary. As soon as we started working on the project, we realised we needed to get clear on what certain words meant: what was a logline, a range, a phase, a key moment? Were the back-end people using these words in the same way design and product was? Quickly writing up a glossary of terms meant everyone was instantly speaking the same language. There was no “Ah, I misunderstood because in the data structure x means y” or, even worse, accidental seepage of technical language into the user interface copy.

Put a glossary of your internal terminology somewhere big and fat on the wall. Stand around it and argue until you agree on what it says. Leave it up; don’t underestimate the power of ambient communication and physical reference.

Plan more, download less

While internet is forbidden inside the fort, we did go on downloading expeditions: NASA photography; code documentation; and so on. The project wouldn’t have been possible without a few trips to the web. We had two lists on the wall: groceries and supplies; internets – “loo roll; Tom Stafford photo“.

This changed our usual design process, forcing us to plan carefully and think of what we needed ahead of time. Getting to the internet was a thirty-minute hike up a snow covered cliff to the town airport, so you really had to need it, too. 

 The path to the internet

For the visual design, especially, this resulted in more focus up front, and communication between the designers on what assets we required. It made us make decisions earlier and stick with them, creating less distraction and churn later in the process. 

Try it at home: unplug once you’ve got the things you need. As an artist, it’s easier to let your inner voice shine through if you’re not looking at other people’s work while creating.

Social design

Finally, our design team experimented with a collaborative approach to wireframing. Once we had collectively nailed down use cases, IA, user journeys and other critical artefacts, we tried a pairing approach. One person drew in Illustrator in real time as the other two articulated what to draw. (This would work equally well with two people, but with three it meant that one of us could jump up and consult the lore on the walls or clarify a technical detail.) The result: we ended up considering more alternatives and quickly rallying around one solution, and resolved difficult problems more quickly.

At a certain stage we discovered it was more efficient for one person to take over – this happened around the time when the basic wireframes existed in Illustrator and we’d collectively run through the use cases, making sure that everything was accounted for in a broad sense. At this point, take a break, go have a beer, and give yourself a pat on the back.

Put the files somewhere accessible so everyone can use them as their base, and divide up the more detailed UI problems, screens or journeys. At this level of detail it’s better to have your personal headspace.

Gavin called this ‘social design’. Chatting and drawing in real time turned what was normally a rather solitary act into a very social process, with some really promising results. I’d tried something like this before with product or developer folks, and it can work – but there’s something really beautiful about switching places and everyone involved being equally quick at drawing. That’s not something you get with non-designers, and frequent swapping of the ‘driver’ and ‘observer’ roles is a key aspect to pairing.

Tackle the forest collectively and the trees individually – it will make your framework more robust and your details more polished. Win/win. 

The return home

Grateful to see a 3G signal on our phones again, our flight off the island was delayed, allowing for a flurry of domain name look-ups, Twitter catch-up, and e-mails to loved ones. A week in an isolated fort really made me appreciate continuous connectivity, but also just how unique some of these processes might be. 

You just never know what crazy place you might be designing from next.",2010,Hannah Donovan,hannahdonovan,2010-12-09T00:00:00+00:00,https://24ways.org/2010/extreme-design/,process
238,Everything You Wanted To Know About Gradients (And a Few Things You Didn’t),"Hello. I am here to discuss CSS3 gradients. Because, let’s face it, what the web really needed was more gradients.

Still, despite their widespread use (or is it overuse?), the smartly applied gradient can be a valuable contributor to a designer’s vocabulary. There’s always been a tension between the inherently two-dimensional nature of our medium, and our desire for more intensity, more depth in our designs. And a gradient can evoke so much: the splay of light across your desk, the slow decrease in volume toward the end of your favorite song, the sunset after a long day. When properly applied, graded colors bring a much needed softness to our work.

Of course, that whole ‘proper application’ thing is the tricky bit.

But given their place in our toolkit and their prominence online, it really is heartening to see we can create gradients directly with CSS. They’re part of the draft images module, and implemented in two of the major rendering engines.

Still, I’ve always found CSS gradients to be one of the more confusing aspects of CSS3. So if you’ll indulge me, let’s take a quick look at how to create CSS gradients—hopefully we can make them seem a bit more accessible, and bring a bit more art into the browser.

Gradient theory 101 (I hope that’s not really a thing)

Right. So before we dive into the code, let’s cover a few basics. Every gradient, no matter how complex, shares a few common characteristics. Here’s a straightforward one:

 I spent seconds hours designing this gradient. I hope you like it.

At either end of our image, we have a final color value, or color stop: on the left, our stop is white; on the right, black. And more color-rich gradients are no different:

 (Don’t ever really do this. Please. I beg you.)

It’s visually more intricate, sure. But at the heart of it, we have just seven color stops (red, orange, yellow, and so on), making for a fantastic gradient all the way.

Now, color stops alone do not a gradient make. Between each is a transition point, the fail-over point between the two stops. Now, the transition point doesn’t need to fall exactly between stops: it can be brought closer to one stop or the other, influencing the overall shape of the gradient.

A tale of two syntaxes

Armed with our new vocabulary, let’s look at a CSS gradient in the wild. Behold, the simple input button:



There’s a simple linear gradient applied vertically across the button, moving from a bright sunflowerish hue (#FAA51A, for you hex nuts in the audience) to a much richer orange (#F47A20). And here’s the CSS that makes it happen:

input[type=submit] {
	background-color: #F47A20;
	background-image: -moz-linear-gradient(
		#FAA51A,
		#F47A20
		);
	background-image: -webkit-gradient(linear, 0 0, 0 100%,
		color-stop(0, #FAA51A),
		color-stop(1, #F47A20)
		);
}

I’ve borrowed David DeSandro’s most excellent formatting suggestions for gradients to make this snippet a bit more legible but, still, the code above might have turned your stomach a bit. And that’s perfectly understandable—heck, it sort of turned mine. But let’s step through the CSS slowly, and see if we can’t make it a little less terrifying.

Verbose WebKit is verbose

Here’s the syntax for our little gradient on WebKit:

background-image: -webkit-gradient(linear, 0 0, 0 100%,
	color-stop(0, #FAA51A),
	color-stop(1, #F47A20)
	);

Woof. Quite a mouthful, no? Well, here’s what we’re looking at:


	WebKit has a single -webkit-gradient property, which can be used to create either linear or radial gradients.
	The next two values are the starting and ending positions for our gradient (0 0 and 0 100%, respectively). Linear gradients are simply drawn along the path between those two points, which allows us to change the direction of our gradient simply by altering its start and end points.
	Afterward, we specify our color stops with the oh-so-aptly named color-stop parameter, which takes the stop’s position on the gradient (0 being the beginning, and 100% or 1 being the end) and the color itself.


For a simple two-color gradient like this, -webkit-gradient has a bit of shorthand notation to offer us:

background-image: -webkit-gradient(linear, 0 0, 0 100%,
	from(#FAA51A),
	to(#FAA51A)
	);

from(#FAA51A) is equivalent to writing color-stop(0, #FAA51A), and to(#FAA51A) is the same as color-stop(1, #FAA51A) or color-stop(100%, #FAA51A)—in both cases, we’re simply declaring the first and last color stops in our gradient.

Terse Gecko is terse

WebKit proposed its syntax back in 2008, heavily inspired by the way gradients are drawn in the canvas specification. However, a different, leaner syntax came to the fore, eventually appearing in a draft module specification in CSS3.

Naturally, because nothing on the web was meant to be easy, this is the one that Mozilla has implemented.

Here’s how we get gradient-y in Gecko:

background-image: -moz-linear-gradient(
	#FAA51A,
	#F47A20
	);

Wait, what? Done already? That’s right. By default, -moz-linear-gradient assumes you’re trying to create a vertical gradient, starting from the top of your element and moving to the bottom. And, if that’s the case, then you simply need to specify your color stops, delimited with a few commas.

I know: that was almost… painless. But the W3C/Mozilla syntax also affords us a fair amount of flexibility and control, by introducing features as we need them.

We can specify an origin point for our gradient:

background-image: -moz-linear-gradient(50% 100%,
	#FAA51A,
	#F47A20
	);

As well as an angle, to give it a direction:

background-image: -moz-linear-gradient(50% 100%, 45deg,
	#FAA51A,
	#F47A20
	);

And we can specify multiple stops, simply by adding to our comma-delimited list:

background-image: -moz-linear-gradient(50% 100%, 45deg,
	#FAA51A,
	#FCC,
	#F47A20
	);

By adding a percentage after a given color value, we can determine its position along the gradient path:

background-image: -moz-linear-gradient(50% 100%, 45deg,
	#FAA51A,
	#FCC 20%,
	#F47A20
	);

So that’s some of the flexibility implicit in the W3C/Mozilla-style syntax.

Now, I should note that both syntaxes have their respective fans. I will say that the W3C/Mozilla-style syntax makes much more sense to me, and lines up with how I think about creating gradients. But I can totally understand why some might prefer WebKit’s more verbose approach to the, well, looseness behind the -moz syntax. À chacun son gradient syntax.

Still, as the language gets refined by the W3C, I really hope some consensus is reached by the browser vendors. And with Opera signaling that it will support the W3C syntax, I suppose it falls on WebKit to do the same.

Reusing color stops for fun and profit

But CSS gradients aren’t all simple colors and shapes and whatnot: by getting inventive with individual color stops, you can create some really complex, compelling effects.

Tim Van Damme, whose brain, I believe, should be posthumously donated to science, has a particularly clever application of gradients on The Box, a site dedicated to his occasional podcast series. Now, there are a fair number of gradients applied throughout the UI, but it’s the feature image that really catches the eye.

You see, there’s nothing that says you can’t reuse color stops. And Tim’s exploited that perfectly.

He’s created a linear gradient, angled at forty-five degrees from the top left corner of the photo, starting with a fully transparent white (rgba(255, 255, 255, 0)). At the halfway mark, he’s established another color stop at an only slightly more opaque white (rgba(255, 255, 255, 0.1)), making for that incredibly gradual brightening toward the middle of the photo.



But then he has set another color stop immediately on top of it, bringing it back down to rgba(255, 255, 255, 0) again. This creates that fantastically hard edge that diagonally bisects the photo, giving the image that subtle gloss.



And his final color stop ends at the same fully transparent white, completing the effect. Hot? I do believe so.

Rocking the radials

We’ve been looking at linear gradients pretty exclusively. But I’d be remiss if I didn’t at least mention radial gradients as a viable option, including a modest one as a link accent on a navigation bar:



And here’s the relevant CSS:

background: -moz-radial-gradient(50% 100%, farthest-side,
	rgb(204, 255, 255) 1%,
	rgb(85, 85, 85) 15%,
	rgba(85, 85, 85, 0)
	);
background: -webkit-gradient(radial, 50% 100%, 0, 50% 100%, 15,
	from(rgb(204, 255, 255)),
	to(rgba(85, 85, 85, 0))
	);

Now, the syntax builds on what we’ve already learned about linear gradients, so much of it might be familiar to you, picking out color stops and transition points, as well as the two syntaxes’ reliance on either a separate property (-moz-radial-gradient) or parameter (-webkit-gradient(radial, …)) to shift into circular mode.

Mozilla introduces another stand-alone property (-moz-radial-gradient), and accepts a starting point (50% 100%) from which the circle radiates. There’s also a size constant defined (farthest-side), which determines the reach and shape of our gradient.

WebKit is again the more verbose of the two syntaxes, requiring both starting and ending points (50% 100% in both cases). Each also accepts a radius in pixels, allowing you to control the skew and breadth of the circle.

Again, this is a fairly modest little radial gradient. Time and article length (and, let’s be honest, your author’s completely inadequate grasp of geometry) prevent me from covering radial gradients in much more detail, because they are incredibly powerful. For those interested in learning more, I can’t recommend the references at Mozilla and Apple strongly enough.

Leave no browser behind

But no matter the kind of gradients you’re working with, there is a large swathe of browsers that simply don’t support gradients. Thankfully, it’s fairly easy to declare a sensible fallback—it just depends on the kind of fallback you’d like. Essentially, gradient-blind browsers will disregard any properties containing references to either -moz-linear-gradient, -moz-radial-gradient, or -webkit-gradient, so you simply need to keep your fallback isolated from those properties.

For example: if you’d like to fall back to a flat color, simply declare a separate background-color:

.nav {
	background-color: #000;
	background-image: -moz-linear-gradient(rgba(0, 0, 0, 0), rgba(255, 255, 255, 0.45));
	background-image: -webkit-gradient(linear, 0 0, 0 100%, from(rgba(0, 0, 0, 0)), to(rgba(255, 255, 255, 0.45)));
}

Or perhaps just create three separate background properties.

.nav {
	background: #000;
	background: #000 -moz-linear-gradient(rgba(0, 0, 0, 0), rgba(255, 255, 255, 0.45));
	background: #000 -webkit-gradient(linear, 0 0, 0 100%, from(rgba(0, 0, 0, 0)), to(rgba(255, 255, 255, 0.45)));
}

We can even build on this to fall back to a non-gradient image:

.nav {
	background: #000 <strong>url(""faux-gradient-lol.png"") repeat-x</strong>;
	background: #000 -moz-linear-gradient(rgba(0, 0, 0, 0), rgba(255, 255, 255, 0.45));
	background: #000 -webkit-gradient(linear, 0 0, 0 100%, from(rgba(0, 0, 0, 0)), to(rgba(255, 255, 255, 0.45)));
}

No matter the approach you feel most appropriate to your design, it’s really just a matter of keeping your fallback design quarantined from its CSS3-ified siblings.

(If you’re feeling especially masochistic, there’s even a way to get simple linear gradients working in IE via Microsoft’s proprietary filters. Of course, those come with considerable performance penalties that even Microsoft is quick to point out, so I’d recommend avoiding those.

And don’t tell Andy Clarke I told you, or he’ll probably unload his Derringer at me. Or something.)

Go forth and, um, gradientify!

It’s entirely possible your head’s spinning. Heck, mine is, but that might be the effects of the ’nog. But maybe you’re wondering why you should care about CSS gradients. After all, images are here right now, and work just fine. 

Well, there are some quick benefits that spring to mind: fewer HTTP requests are needed; CSS3 gradients are easily made scalable, making them ideal for variable widths and heights; and finally, they’re easily modifiable by tweaking a few CSS properties. Because, let’s face it, less time spent yelling at Photoshop is a very, very good thing.

Of course, CSS-generated gradients are not without their drawbacks. The syntax can be confusing, and it’s still under development at the W3C. As we’ve seen, browser support is still very much in flux. And it’s possible that gradients themselves have some real performance drawbacks—so test thoroughly, and gradient carefully.

But still, as syntaxes converge, and support improves, I think generated gradients can make a compelling tool in our collective belts. The tasteful design is, of course, entirely up to you.

So have fun, and get gradientin’.",2010,Ethan Marcotte,ethanmarcotte,2010-12-22T00:00:00+00:00,https://24ways.org/2010/everything-you-wanted-to-know-about-gradients/,code
226,Documentation-Driven Design for APIs,"Documentation is like gift wrapping.  It seems like superfluous fluff, but your family tends to be rather disappointed when their presents arrive in supermarket carrier bags, so you have to feign some sort of attempt at making your gift look enticing.  Documentation doesn’t have to be all hard work and sellotaping yourself to a table – you can make it useful and relevant.

Documentation gets a pretty rough deal. It tends to get left until the end of a project, when some poor developer is assigned the ‘document project’ ticket and wades through each feature of Whizzy New API 3.0 and needs to recall exactly what each method is meant to do. That’s assuming any time is left for documentation at all. The more common outcome resembles last minute homework scribbled on a post-it note, where just the bare bones of what’s available are put out for your users, and you hope that you’ll spot the inconsistencies and mistakes before they do.

Wouldn’t it be nicer for everyone if you could make documentation not only outstanding for your users, but also a valuable tool for your development team – so much so that you couldn’t imagine writing a line of code before you’d documented it?

Documentation needs to have three main features:


	It should have total coverage and document all the features of your project.  Private methods should be documented for your developers, and public features need to be available to your users.
	It should be consistent – a user should know what to expect from your documentation, and terminology should be accurate to your language.
	It should be current – and that means staying accurate as new versions of your code base are released.


But you can also get these bonuses:


	Act as a suggested specification – a guide that will aid a developer in making something consistent and usable.
	It can test your API quality.
	It can enhance the communication skills within your development team.


So how do we get our documentation to be rich and full of features, instead of a little worn out like Boxing Day leftovers?

Write your documentation first

When I say first, I mean first. Not after you’ve started writing the code. Not even after you’ve started writing your unit tests. First. You may or may not have been provided with a decent specification, but the first job should be to turn your requirements for a feature into documentation.  

It works best when it takes the form of in-code comments. It works even better when your in-code comments take a standard documentation format that you can later use to generate published documentation for your users. This has the benefit of immediately making your docs as version controlled as your code-base, and it saves having to rewrite, copy or otherwise harass your docs into something legible later on. 

Almost all languages have a self-documentation format these days. My choice of format for JavaScript is JSDocToolkit, and the sort of things I look for are the ability to specify private and public methods, full options object statements (opts as Opts only is a no-no), and the ability to include good examples.

So, our example for today will be a new festive feature for a JavaScript API. We’ve been asked to specify a sled for Santa to get around the world to give out toys:


	Santa needs to be able to travel around the world in one night to deliver toys to children, and he’ll need some reindeer to pull his sled.


As documentation, it would look like:

/**
@name Sled
@extends Vehicle
@constructor
@description Create a new sled to send Santa around the world to deliver toys to good kids.
	@param {Object} [opts] Options
	@param {number} [opts.capacity='50'] Set the capacity of the sled
	@param {string} [opts.pilot='santa'] The pilot of the sled.
@example
	// Create a sled and specify some reindeer.
	new Sled().reindeer(['Dasher', 'Dancer', 'Prancer', 'Vixen', 'Comet', 'Cupid']);
*/

By breaking it down as documentation, you can, for example, hand this over to another developer without the need to explain the feature in much depth, and they’ll develop something that has to match this piece of documentation. It specifies everything that is important to this feature – its default values and types, and where it inherits other features from.  

We know that we need to specify some way of setting reindeer to pull the sled and also some toys to give, and so we can quickly specify extra methods for the sled:

/*
@name vehicle.Sled#reindeer
@function
@description Set the reindeer that will pull Santa's sled.
	@param {string[]} reindeer A list of the reindeer.
@example
	// specifying some reindeer
	Sled().reindeer(['Dasher', 'Dancer', 'Rudolph', 'Vixen']);
*/
/*
@name vehicle.Sled#toys
@function
@description Add a list of toys and recipients to the Sled.
	@param {Object[]} toys A list of toys and who will receive them.
@example
	// Adding toys to the sled
	Sled().toys([
		{name:'Brian', toy:'Fire Engine'},
		{name:'Drew', toy:'Roller-skates'},
		{name:'Anna', toy:'Play-doh'},
		...
		]);
*/

Job done! You’ve got a specification to share with your team and something useful for your users in the form of full examples, and you didn’t even have to open another text editor.

Use your documentation to share knowledge

Documentation isn’t just for users. It’s also used by internal developers to explain what they’ve written and how it works. This is especially valuable where the team is large or the code-base sprawling.

So, returning to our example, the next step would be to share with the rest of the team (or at least a selection of the team if yours is large) what the documentation looks like. This is useful for two main reasons:


	They can see if they understand what the documentation says the feature will do. It’s best if they haven’t seen the requirement before. If your fellow developers can’t work out what ‘MagicMethodX’ is going to return from the docs, neither can your users.
	They can check that the feature accomplishes everything that they expect to, and that it’s consistent with the rest of the functionality.


On previous projects, we’ve taken to referring to this stage of the development process as the ‘bun fight’.  It’s a chance for everyone to have an honest say and throw a few pies without actually causing anyone to have to rewrite any code. If you can identify at this stage that a feature is over-complicated, lacking or just plain useless, you’ll all be much happier to throw out a few lines of documentation than you may have been to throw out a partial, or even complete, piece of functionality.

Documentation has your back

The final benefit to working in this way is that your documentation not only remains accurate, it’s always as accurate as your latest release. It can’t fall behind. You can increase the likelihood that your docs will remain up to date by unit testing your examples.

Returning to the previous example, we can add a QUnit unit test to the expected output with ease during the build process – we know exactly how the code will look and, with the @example tag, we can identify easily where to find the bits that need testing. If it’s tested it’ll definitely work as you expect it to when a user copy and pastes it. You’re ensuring quality from idea to implementation.

As an extra bauble, the best thing about a system like JSDocToolkit is that it’ll take your inline comments and turn them into beautiful sites, as good systems will allow for customised output templates. You’ll be producing full-featured sites for your projects and plugins with almost no extra effort, but all the benefits.",2010,Frances Berriman,francesberriman,2010-12-11T00:00:00+00:00,https://24ways.org/2010/documentation-driven-design-for-apis/,process
237,Circles of Confusion,"Long before I worked on the web, I specialised in training photographers how to use large format,  5×4″ and 10×8″ view cameras – film cameras with swing and tilt movements, bellows and upside down, back to front images viewed on dim, ground glass screens. It’s been fifteen years since I clicked a shutter on a view camera, but some things have stayed with me from those years.

In photography, even the best lenses don’t focus light onto a point (infinitely small in size) but onto ‘spots’ or circles in the ‘film/image plane’. These circles of light have dimensions, despite being microscopically small. They’re known as ‘circles of confusion’.

As circles of light become larger, the more unsharp parts of a photograph appear. On the flip side, when circles are smaller, an image looks sharper and more in focus. This is the basis for photographic depth of field and with that comes the knowledge that no photograph can be perfectly focused, never truly sharp. Instead, photographs can only be ‘acceptably unsharp’. 

Acceptable unsharpness is now a concept that’s relevant to the work we make for the web, because often – unless we compromise – websites cannot look or be experienced exactly the same across browsers, devices or platforms. Accepting that fact, and learning to look upon these natural differences as creative opportunities instead of imperfections, can be tough. Deciding which aspects of a design must remain consistent and, therefore, possibly require more time, effort or compromises can be tougher. Circles of confusion can help us, our bosses and our customers make better, more informed decisions.

Acceptable unsharpness

Many clients still demand that every aspect of a design should be ‘sharp’ – that every user must see rounded boxes, gradients and shadows – without regard for the implications. I believe that this stems largely from the fact that they have previously been shown designs – and asked for sign-off – using static images.

It’s also true that in the past, organisations have invested heavily in style guides which, while maybe still useful in offline media, have a strictness that often fails to allow for the flexibility that we need to create experiences that are appropriate to a user’s browser or device capabilities.

We live in an era where web browsers and devices have wide-ranging capabilities, and websites can rarely look or be experienced exactly the same across them. Is a particular typeface vital to a user’s experience of a brand? How important are gradients or shadows? Are rounded corners really that necessary? These decisions determine how ‘sharp’ an element should be across browsers with different capabilities and, therefore, how much time, effort or extra code and images we devote to achieving consistency between them. To help our clients make those decisions, we can use circles of confusion.

Circles of confusion

Using circles of confusion involves plotting aspects of a visual design into a series of concentric circles, starting at the centre with elements that demand the most consistency. Then, work outwards, placing elements in order of their priority so that they become progressively ‘softer’, more defocused as they’re plotted into outer rings.

If layout and typography must remain consistent, place them in the centre circle as they’re aspects of a design that must remain ‘sharp’.

When gradients are important – but not vital – to a user’s experience of a brand, plot them close to, but not in the centre. This makes everyone aware that to achieve consistency, you’ll need to carve out extra images for browsers that don’t support CSS gradients.

If achieving rounded corners or shadows in all browsers isn’t important, place them into outer circles, allowing you to save time by not creating images or employing JavaScript workarounds.

I’ve found plotting aspects of a visual design into circles of confusion is a useful technique when explaining the natural differences between browsers to clients. It sets more realistic expectations and creates an environment for more meaningful discussions about progressive and emerging technologies. Best of all, it enables everyone to make better and more informed decisions about design implementation priorities.

Involving clients allows the implications of the decisions they make more transparent. For me, this has sometimes meant shifting deadlines or it has allowed me to more easily justify an increase in fees. Most important of all, circles of confusion have helped the people that I work with move beyond yesterday’s one-size-fits-all thinking about visual design, towards accepting the rich diversity of today’s web.",2010,Andy Clarke,andyclarke,2010-12-23T00:00:00+00:00,https://24ways.org/2010/circles-of-confusion/,process
223,Calculating Color Contrast,"Some websites and services allow you to customize your profile by uploading pictures, changing the background color or other aspects of the design. As a customer, this personalization turns a web app into your little nest where you store your data. As a designer, letting your customers have free rein over the layout and design is a scary prospect. So what happens to all the stock text and images that are designed to work on nice white backgrounds? Even the Mac only lets you choose between two colors for the OS, blue or graphite! Opening up the ability to customize your site’s color scheme can be a recipe for disaster unless you are flexible and understand how to find maximum color contrasts.

In this article I will walk you through two simple equations to determine if you should be using white or black text depending on the color of the background. The equations are both easy to implement and produce similar results. It isn’t a matter of which is better, but more the fact that you are using one at all! That way, even with the craziest of Geocities color schemes that your customers choose, at least your text will still be readable.

Let’s have a look at a range of various possible colors. Maybe these are pre-made color schemes, corporate colors, or plucked from an image.



Now that we have these potential background colors and their hex values, we need to find out whether the corresponding text should be in white or black, based on which has a higher contrast, therefore affording the best readability. This can be done at runtime with JavaScript or in the back-end before the HTML is served up.

There are two functions I want to compare. The first, I call ’50%’. It takes the hex value and compares it to the value halfway between pure black and pure white. If the hex value is less than half, meaning it is on the darker side of the spectrum, it returns white as the text color. If the result is greater than half, it’s on the lighter side of the spectrum and returns black as the text value.

In PHP:

function getContrast50($hexcolor){
    return (hexdec($hexcolor) > 0xffffff/2) ? 'black':'white';
}

In JavaScript:

function getContrast50(hexcolor){
    return (parseInt(hexcolor, 16) > 0xffffff/2) ? 'black':'white';
}

It doesn’t get much simpler than that! The function converts the six-character hex color into an integer and compares that to one half the integer value of pure white. The function is easy to remember, but is naive when it comes to understanding how we perceive parts of the spectrum. Different wavelengths have greater or lesser impact on the contrast.

The second equation is called ‘YIQ’ because it converts the RGB color space into YIQ, which takes into account the different impacts of its constituent parts. Again, the equation returns white or black and it’s also very easy to implement.

In PHP:

function getContrastYIQ($hexcolor){
	$r = hexdec(substr($hexcolor,0,2));
	$g = hexdec(substr($hexcolor,2,2));
	$b = hexdec(substr($hexcolor,4,2));
	$yiq = (($r*299)+($g*587)+($b*114))/1000;
	return ($yiq >= 128) ? 'black' : 'white';
}

In JavaScript:

function getContrastYIQ(hexcolor){
	var r = parseInt(hexcolor.substr(0,2),16);
	var g = parseInt(hexcolor.substr(2,2),16);
	var b = parseInt(hexcolor.substr(4,2),16);
	var yiq = ((r*299)+(g*587)+(b*114))/1000;
	return (yiq >= 128) ? 'black' : 'white';
}

You’ll notice first that we have broken down the hex value into separate RGB values. This is important because each of these channels is scaled in accordance to its visual impact. Once everything is scaled and normalized, it will be in a range between zero and 255. Much like the previous ’50%’ function, we now need to check if the input is above or below halfway. Depending on where that value is, we’ll return the corresponding highest contrasting color.

That’s it: two simple contrast equations which work really well to determine the best readability.

If you are interested in learning more, the W3C has a few documents about color contrast and how to determine if there is enough contrast between any two colors. This is important for accessibility to make sure there is enough contrast between your text and link colors and the background.

There is also a great article by Kevin Hale on Particletree about his experience with choosing light or dark themes. To round it out, Jonathan Snook created a color contrast picker which allows you to play with RGB sliders to get values for YIQ, contrast and others. That way you can quickly fiddle with the knobs to find the right balance.

Comparing results

Let’s revisit our color schemes and see which text color is recommended for maximum contrast based on these two equations.



If we use the simple ’50%’ contrast function, we can see that it recommends black against all the colors except the dark green and purple on the second row. In general, the equation feels the colors are light and that black is a better choice for the text.



The more complex ‘YIQ’ function, with its weighted colors, has slightly different suggestions. White text is still recommended for the very dark colors, but there are some surprises. The red and pink values show white text rather than black. This equation takes into account the weight of the red value and determines that the hue is dark enough for white text to show the most contrast.

As you can see, the two contrast algorithms agree most of the time. There are some instances where they conflict, but overall you can use the equation that you prefer. I don’t think it is a major issue if some edge-case colors get one contrast over another, they are still very readable.

Now let’s look at some common colors and then see how the two functions compare. You can quickly see that they do pretty well across the whole spectrum.



In the first few shades of grey, the white and black contrasts make sense, but as we test other colors in the spectrum, we do get some unexpected deviation. Pure red #FF0000 has a flip-flop. This is due to how the ‘YIQ’ function weights the RGB parts. While you might have a personal preference for one style over another, both are justifiable.



In this second round of colors, we go deeper into the spectrum, off the beaten track. Again, most of the time the contrasting algorithms are in sync, but every once in a while they disagree. You can select which you prefer, neither of which is unreadable.

Conclusion

Contrast in color is important, especially if you cede all control and take a hands-off approach to the design. It is important to select smart defaults by making the contrast between colors as high as possible. This makes it easier for your customers to read, increases accessibility and is generally just easier on the eyes. 

Sure, there are plenty of other equations out there to determine contrast; what is most important is that you pick one and implement it into your system.

So, go ahead and experiment with color in your design. You now know how easy it is to guarantee that your text will be the most readable in any circumstance.",2010,Brian Suda,briansuda,2010-12-24T00:00:00+00:00,https://24ways.org/2010/calculating-color-contrast/,code
217,Beyond Web Mechanics – Creating Meaningful Web Design,"It was just over three years ago when I embarked on becoming a web designer, and the first opinion piece about the state of web design I came across was a conference talk by Elliot Jay Stocks called ‘Destroy the Web 2.0 Look’. Elliot’s presentation was a call to arms, a plea to web designers the world over to stop the endless reproductions of the so called ‘Web 2.0 look’.

Three and a half years on from Elliot’s talk, what has changed? Well, from an aesthetic standpoint, not a whole lot. The Web 2.0 look has evolved, but it’s still with us and much of the web remains filled with cookie cutter websites that bear a striking resemblance to one another. This wouldn’t matter so much if these websites were selling comparable services or products, but they’re not. They look similar, they follow the same web design trends; their aesthetic style sends out a very similar message, yet they’re selling completely different services or products. How can you be communicating effectively with your users when your online book store is visually indistinguishable from an online cosmetic store? This just doesn’t make sense. 

I don’t want to belittle the current version of the Web 2.0 look for the sake of it. I want to talk about the opportunity we have as web designers to create more meaningful experiences for the people using our websites. Using design wisely gives us the ability to communicate messages, ideas and attitudes that our users will understand and connect with.

Being human

As human beings we respond emotionally to everything around us – people, objects, posters, packaging or websites. We also respond in different ways to different kinds of aesthetic design and style. We care about style and aesthetics deeply, whether we realise it or not. Aesthetic design has the power to attract or repel. We often make decisions based purely on aesthetics and style – and don’t retailers the world over know it! We connect attitudes and strongly held beliefs to style. Individuals will proudly associate themselves with a certain style or aesthetic because it’s an expression of who they are. You know that old phrase, ‘Don’t judge a book by its cover’?  Well, the problem is that people do, so it’s important we get the cover right.

Much is made of how to structure web pages, how to create a logical information hierarchy, how to use layout and typography to clearly communicate with your users. It’s important, however, not to mistake clarity of information or legibility with getting your message across. Few users actually read websites word by word: it’s far more likely they’ll just scan the page. If the page is copy-heavy and nothing grabs their attention, they may well just move on. This is why it’s so important to create a visual experience that actually means something to the user. 

Meaningful design

When we view a poster or website, we make split-second assessments and judgements of what is in front of us. Our first impressions of what a website does or who it is aimed at are provoked by the style and aesthetic of the website. For example, with clever use of colour, typography, graphic design and imagery we can communicate to users that an organisation is friendly, edgy, compassionate, fun or environmentally conscious.

Using a certain aesthetic we can convey the personality of that organisation, target age ranges, different sexes or cultural groups, communicate brand attributes, and more. We can make our users feel like they’re part of something and, perhaps even more importantly, we can make new users want to be a part of something. And we can achieve all this before the user has read a single word. 

By establishing a website’s aesthetic and creating a meaningful visual language, a design is no longer just a random collection of pretty gradients that have been plucked out of thin air. There can be a logic behind the design decisions we make. So, before you slap another generic piece of ribbon or an ultra shiny icon into the top-left corner of your website, think about why you are doing it. If you can’t come up with a reason better than “I saw it on another website”, it’s probably a poor application of style.

Design and style

There are a number of reasons why the web suffers from a lack meaningful design. Firstly, there are too many preconceptions of what a website should look like. It’s too easy for designers to borrow styles from other websites, thereby limiting the range of website designs we see on the web. Secondly, many web designers think of aesthetic design as of secondary importance, which shouldn’t be the case. Designing websites that are accessible and easy to use is, of course, very important but this is the very least a web designer should be delivering. Easy to use websites should come as standard – it’s equally important to create meaningful, compelling and beautiful experiences for everyone who uses our websites. The aesthetics of your site are part of the design, and to ignore this and play down the role of aesthetic design is just a wasted opportunity. 

No compromise necessary

Easy to use, accessible websites and beautiful, meaningful aesthetics are not mutually exclusive. The key is to apply style and aesthetic design appropriately. We need to think about who and what we’re designing for and ask ourselves why we’re applying a certain kind of aesthetic style to our design. If you do this, there’s no reason why effective, functional design should come at the expense of jaw-dropping, meaningful aesthetics.

Web designers need to understand the differences between functional design and aesthetic design but, even more importantly, they need to know how to make them work together.  It’s combining these elements of design successfully that makes for the best web design in the world.",2010,Mike Kus,mikekus,2010-12-05T00:00:00+00:00,https://24ways.org/2010/beyond-web-mechanics-creating-meaningful-web-design/,design
227,A Contentmas Epiphany,"The twelve days of Christmas fall between 25 December, Christmas Day, and 6 January, the Epiphany of the Kings. Traditionally, these have been holidays and a lot of us still take a good proportion of these days off. Equally, a lot of us have a got a personal site kicking around somewhere that we sigh over and think, “One day I’ll sort you out!” Why not take this downtime to give it a big ol’ refresh? I know, good idea, huh?

HEY WAIT! WOAH! NO-ONE’S TOUCHING PHOTOSHOP OR DOING ANY CSS FANCYWORK UNTIL I’M DONE WITH YOU!

Be honest, did you immediately think of a sketch or mockup you have tucked away? Or some clever little piece of code you want to fiddle with? Now ask yourself, why would you start designing the container if you haven’t worked out what you need to put inside?

Anyway, forget the content strategy lecture; I haven’t given you your gifts yet.
I present The Twelve Days of Contentmas!

This is a simple little plan to make sure that your personal site, blog or portfolio is not just looking good at the end of these twelve days, but is also a really useful repository of really useful content.

WARNING KLAXON: There are twelve parts, one for each day of Christmas, so this is a lengthy article. I’m not expecting anyone to absorb this in one go. Add to Instapaper. There is no TL;DR for this because it’s a multipart process, m’kay? Even so, this plan of mine cuts corners on a proper applied strategy for content. You might find some aspects take longer than the arbitrary day I’ve assigned. And if you apply this to your company-wide intranet, I won’t be held responsible for the mess.

That said, I encourage you to play along and sample some of the practical aspects of organising existing content and planning new content because it is, honestly, an inspiring and liberating process. For one thing, you get to review all the stuff you have put out for the world to look at and see what you could do next. This always leaves me full of ideas on how to plug the gaps I’ve found, so I hope you are similarly motivated come day twelve.

Let’s get to it then, shall we?

On the first day of Contentmas, Relly gave to me:

1. A (partial) content inventory

I’m afraid being a site owner isn’t without its chores. With great power comes great responsibility and all that. There are the domain renewing, hosting helpline calls and, of course, keeping on top of all the content that you have published.

If you just frowned a little and thought, “Well, there’s articles and images and… stuff”, then I’d like to introduce you to the idea of a content inventory. 

A content inventory is a list of all your content, in a simple spreadsheet, that allows you to see at a glance what is currently on your site: articles; about me page; contact form, and so on.

You add the full URL so that you can click directly to any page listed. You add a brief description of what it is and what tags it has. In fact, I’ll show you. I’ve made a Google Docs template for you. Sorry, it isn’t wrapped.

Does it seem like a mammoth task? Don’t feel you have to do this all in one day. But do do it. For one thing, looking back at all the stuff you’ve pushed out into the world gives you a warm fuzzy feeling which keeps the heating bill down.

Grab a glass of mulled cider and try going month-by-month through your blog archives, or project-by-project through your portfolio. Do a little bit each day for the next twelve days and you’ll have done something awesome. The best bit is that this exploration of your current content helps you with the next day’s task.

Bonus gift: for more on content auditing and inventory, check out Jeff Veen’s article on just this topic, which is also suitable for bigger business sites too.

On the second day of Contentmas, Relly gave to me:

2. Website loves

Remember when you were a kid, you’d write to Santa with a wish list that would make your parents squirm, because your biggest hope for your stocking would be either impossible or impossibly expensive. Do you ever get the same thing now as a grown-up where you think, “Wouldn’t it be great if I could make a video blog every week”, or “I could podcast once a month about this”, and then you push it to the back of your mind, assuming that you won’t have time or you wouldn’t know what to talk about anyway?

True fact: content doesn’t just have to be produced when we are so incensed that we absolutely must blog about a topic. Neither does it have to be a drain to a demanding schedule. You can plan for it. In fact, you’re about to.

So, today, get a pen and a notebook. Move away from your computer. My gift to you is to grab a quiet ten minutes between turkey sandwiches and relatives visiting and give your site some of the attention it deserves for 2011.

What would you do with your site if you could? I don’t mean what would you do purely visually – although by all means note those things down too – but to your site as a whole. Here are some jumping off points:


	Would you like to individually illustrate and design some of your articles?
	What about a monthly exploration of your favourite topic through video or audio?
	Who would you like to collaborate with?
	What do you want your site to be like for a user?
	What tone of voice would you like to use?
	How could you use imagery and typography to support your content?
	What would you like to create content about in the new year?


It’s okay if you can’t do these things yet. It’s okay to scrub out anything where you think, “Nah, never gonna happen.” But do give some thought to what you might want to do next. The best inspiration for this comes from what you’ve already done, so keep on with that inventory.

Bonus gift: a Think Vitamin article on podcasting using Skype, so you can rope in a few friends to join in, too.

On the third day of Contentmas, Relly gave to me:

3. Red pens

Shock news, just in: the web is not print!

One of the hardest things as a writer is to reach the point where you say, “Yeah, okay, that’s it. I’m done” and send off your beloved manuscript or article to print. I’m convinced that if deadlines didn’t exist, nothing would get finished. Why? Well, at the point you hand it over to the publishing presses, you can make no more changes. At best, you can print an erratum or produce an updated second edition at a later date. And writers love to – no, they live to – tweak their creations, so handing them over is quite a struggle. Just one more comma and…

Online, we have no such constraints. We can edit, correct, test, tweak, twiddle until we’re blooming sick of it. Our red pens never run out of ink. It is time for you to run a more critical eye over your content, especially the stuff already published. Relish in the opportunity to change stuff on the fly. I am not so concerned by blog articles and such (although feel free to apply this concept to those, too), but mainly by your more concrete content: about pages; contact pages; home page navigation; portfolio pages; 404 pages.

Now, don’t go running amok with the cut function yet. First, put all these evergreen pages into your inventory. In the notes section, write a quick analysis of how useful this copy is. Example questions:


	Is your contact page up-to-date?
	Does your about page link to the right places?
	Is your portfolio current?
	Does your 404 page give people a way to find what they were looking for?


We’ll come back to this in a few days once we have a clearer idea of how to improve our content.

Bonus gift: the audio and slides of a talk I gave on microcopy and 404 pages at @media WebDirections last year.

On the fourth day of Contentmas, Relly gave to me:

4. Stalling nerds

Actually, I guess more accurately this is something I get given a lot. Designers and developers particularly can find a million ways to extract themselves from the content of a site but, as the site owner,  and this being your personal playground and all, you mustn’t. You actually can’t, sorry. 

But I do understand that at this point, ‘sorting out your site’ suddenly seems a lot less exciting, especially if you are a visually-minded person and words and lists aren’t really your thing. So far, there has been a lot of not-very-exciting exercises in planning, and there’s probably a nice pile of DVDs and video games that you got from Santa worth investigating. 

Stay strong my friend. By now, you have probably hit upon an idea of some sort you are itching to start on, so for every half-hour you spend doing inventory, gift yourself another thirty minutes to play with that idea.

Bonus gift: the Pomodoro Technique. Take one kitchen timer and a to-do list and see how far you can go.

On the fifth day of Contentmas, Relly gave to me:

5. Golden rules

Here are some guidelines for writing online:


	Make headlines for tutorials and similar content useful and descriptive; use a subheading for any terrible pun you want to work in.



	Create a broad opening paragraph that addresses what your article is about. Part of the creative skill in writing is to do this in a way that both informs the reader and captures their attention. If you struggle with this, consider a boxout giving a summary of the article.



	Use headings to break up chunks of text and allow people to scan. Most people will have a scoot about an article before starting at the beginning to give it a proper read. These headings should be equal parts informative and enticing. Try them out as questions that might be posed by the reader too.



	Finish articles by asking your reader to take an affirmative action: subscribe to your RSS feed; leave a comment (if comments are your thing – more on that later); follow you on Twitter; link you to somewhere they have used your tutorial or code. The web is about getting excited, making things and sharing with others, so give your readers the chance to do that.



	For portfolio sites, this call to action is extra important as you want to pick up new business. Encourage people to e-mail you or call you – don’t just rely on a number in the footer or an e-mail link at the top. Think up some consistent calls-to-action you can use and test them out.


So, my gift to you today is a simplified page table for planning out your content to make it as useful as possible.

Feel free to write a new article or tutorial, or work on that great idea from yesterday and try out these guidelines for yourself. 

It’s a simple framework – good headline; broad opening; headings to break up volume; strong call to action – but it will help you recognise if what you’ve written is in good shape to face the world. It doesn’t tell you anything about how to create it – that’s your endeavour – but it does give you a start. No more staring at a blank page.

Bonus gift: okay, you have to buy yourself this one, but it is the gift that keeps on giving: Ginny Reddish’s Letting Go of the Words – the hands down best guide to web writing there is, with a ton of illustrative examples.

On the sixth day of Contentmas, Relly gave to me:

6. Foundation-a-laying

Yesterday, we played with a page table for articles. Today, we are going to set the foundations for your new, spangly, spruced up, relaunched site (for when you’re ready, of course). We’ve checked out what we’ve got, we’ve thought about what we’d like, we have a wish list for the future. Now is the time for a small reality check. 

Be realistic with yourself. Can you really give your site some attention every day? Record a short snippet of audio once a week? A photo diary post once a month? Look back at the wish list you made.


	What can you do?
	What can you aim for?
	What just isn’t possible right now?


As much as we’d all love to be producing a slick video podcast and screencast three times a week, it’s better to set realistic expectations and work your way up.

Where does your site sit in your online world?


	Do you want it to be the hub of all your social interactions, a lifestream, a considered place of publication or a free for all?
	Do you want to have comments (do you have the personal resource to monitor comments?) or would you prefer conversation to happen via Twitter, Facebook or not at all?
	Does this apply to all pages, posts and content types or just some?
	Get these things straight in your head and it’s easier to know what sort of environment you want to create and what content you’ll need to sustain it.


Get your notebook again and think about specific topics you’d like to cover, or aspects of a project you want to go into more, and how you can go ahead and do just that. A good motivator is to think what you’ll get out of doing it, even if that is “And I’ll finally show the poxy $whatever_community that my $chosen_format is better than their $other_format.”

What topics have you really wanted to get off your chest? Look through your inventory again. What gaps are there in your content just begging to be filled?

Today, you’re going to give everyone the gift of your opinion. Find one of those things where someone on the internet is wrong and create a short but snappy piece to set them straight. Doesn’t that feel good? Soon you’ll be able to do this in a timely manner every time someone is wrong on the internet!

Bonus gift: we’re halfway through, so I think something fun is in order. How about a man sledding naked down a hill in Brighton on a tea tray? Sometimes, even with a whole ton of content planning, it’s the spontaneous stuff that is still the most fun to share.

On the seventh day of Contentmas, Relly gave to me:

7. Styles-a-guiding

Not colour style guides or brand style guides or code style guides. Content style guides. You could go completely to town and write yourself a full document defining every aspect of your site’s voice and personality, plus declaring your view on contracted phrases and the Oxford comma, but this does seem a tad excessive. Unless you’re writing an entire site as a fictional character, you probably know your own voice and vocabulary better than anyone. It’s in your head, after all.

Instead, equip yourself with a good global style guide (I like the Chicago Manual of Style because I can access it fully online, but the Associated Press (AP) Stylebook has a nifty iPhone app and, if I’m entirely honest, I’ve found a copy of Eats, Shoots and Leaves has set me right on all but the most technical aspects of punctuation). Next, pick a good dictionary and bookmark thesaurus.com. Then have a go at Kristina Halvorson’s ‘Voice and Tone’ exercise from her book Content Strategy for the Web, to nail down what you’d like your future content to be like:

To introduce the voice and tone qualities you’re [looking to create], a good approach is to offer contrasting values. For example:


	Professional, not academic.
	Confident, not arrogant.
	Clever, not cutesy.
	Savvy, not hipster.
	Expert, not preachy.



Take a look around some of your favourite sites and examine the writing and stylistic handling of content. What do you like? What do you want to emulate? What matches your values list?

Today’s gift to you is an idea. Create a ‘swipe file’ through Evernote or Delicious and save all the stuff you come across that, regardless of topic, makes you think, “That’s really cool.” This isn’t the same as an Instapaper list you’d like to read. This is stuff you have read or have seen that is worth looking at in closer detail.


	Why is it so good?
	What is the language and style like?
	What impact does the typography have?
	How does the imagery work to enhance the message?


This isn’t about creating a personal brand or any such piffle. It’s about learning to recognise how good content works and how to create something awesome yourself. Obviously, your ideas are brilliant, so take the time to understand how best to spring them on the unsuspecting public for easier world domination.

Bonus gift: a nifty style guide is a must when you do have to share content creation duties with others. Here is Leeds University’s publicly available PDF version for you to take a gander at. I especially like the Rationale sections for chopping off dissenters at the knees. 

On the eighth day of Contentmas, Relly gave to me:

8. Times-a-making

You have an actual, real plan for what you’d like to do with your site and how it is going to sound (and probably some ideas on how it’s going to look, too). I hope you are full of enthusiasm and Getting Excited To Make Things. Just before we get going and do exactly that, we are going to make sure we have made time for this creative outpouring.

Have you tried to blog once a week before and found yourself losing traction after a month or two? Are there a couple of podcasts lurking neglected in your archives? Whereas half of the act of running is showing up for training, half of creating is making time rather than waiting for it to become urgent. It’s okay to write something and set a date to come back to it (which isn’t the same as leaving it to decompose in your drafts folder).

Putting a date in your calendar to do something for your site means that you have a forewarning to think of a topic to write about, and space in your schedule to actually do it. Crucially, you’ve actually made some time for this content lark.

To do this, you need to think about how long it takes to get something out of the door/shipped/published/whatever you want to call it. It might take you just thirty minutes to record a podcast, but also a further hour to research the topic beforehand and another hour to edit and upload the clips. Suddenly, doing a thirty minute podcast every day seems a bit unlikely. But, on the flipside, it is easy to see how you could schedule that in three chunks weekly. 

Put it in your calendar. Do it, publish it, book yourself in for the next week. Keep turning up.

Today my gift to you is the gift of time. Set up your own small content calendar, using your favourite calendar system, and schedule time to play with new ways of creating content, time to get it finished and time to get it on your site. Don’t let good stuff go to your drafts folder to die of neglect.

Bonus gift: lots of writers swear by the concept of ‘daily pages’. That is, churning out whatever is in your head to see if there is anything worth building upon, or just to lose the grocery list getting in the way. 750words.com is a site built around this concept. Go have a play.

On the ninth day of Contentmas, Relly gave to me:

9. Copy enhancing

An incredibly radical idea for day number nine. We are going to look at that list of permanent pages you made back on day three and rewrite the words first, before even looking at a colour palette or picking a font! Crazy as it sounds, doing it this way round could influence your design. It could shape the imagery you use. It could affect your choice of typography. IMAGINE THE POSSIBILITIES!

Look at the page table from day five. Print out one for each of your homepage, about page, contact page, portfolio, archive, 404 page or whatever else you have. Use these as a place to brainstorm your ideas and what you’d like each page to do for your site. Doodle in the margin, choose words you think sound fun to say, daydream about pictures you’d like to use and colours you think would work, but absolutely, completely and utterly fill in those page tables to understand how much (or how little) content you’re playing with and what you need to do to get to ‘launch’.

Then, use them for guidance as you start to write. Don’t skimp. Don’t think that a fancy icon of an envelope encourages people to e-mail you. Use your words.

People get antsy at this bit. Writing can be hard work and it’s easy for me to say, “Go on and write it then!” I know this. I mean, you should see the faces I pull when I have to do anything related to coding. The closest equivalent would be when scientists have to stick their hands in big gloves attached to a glass box to do dangerous experiments.

Here’s today’s gift, a little something about writing that I hope brings you comfort: 


	To write something fantastic you almost always have to write a rubbish draft first.


Now, you might get lucky and write a ‘good enough’ draft first time and that’s fab – you’ve cut some time getting to ‘fantastic’. If, however, you’ve always looked at your first attempt to write more than the bare minimum and sighed in despair, and resigned yourself to adding just a title, date and a screenshot, be cheered because you have taken the first step to being able to communicate with clarity, wit and panache.

Keep going. Look at writing you admire and emulate it. Think about how you will lovingly design those words when they are done. Know that you can go back and change them. Check back with your page table to keep you on track. Do that first draft.

Bonus gift: becoming a better writer helps you to explain design concepts to clients.

On the tenth day of Contentmas, Relly gave to me:

10. Ideas for keeping

Hurrah! You have something down on paper, ready to start evolving your site around it. Here’s where the words and visuals and interaction start to come together. Because you have a plan, you can think ahead and do things you wouldn’t be able to pull together otherwise.


	How about finding a fresh-faced stellar illustrator on Dribbble to create you something perfect to pep up your contact page or visualize your witty statement on statements of work. A List Apart has been doing it for years and it hasn’t worked out too badly for them, has it?



	What about spending this month creating a series of introductory tutorials on a topic, complete with screencasts and audio and give them a special home on your site?



	How about putting in some hours creating a glorious about me page, with a biography, nice picture, and where you spend your time online?



	You could even do the web equivalent of getting up in the attic and sorting out your site’s search to make it easier to find things in your archives. Maybe even do some manual recommendations for relevant content and add them as calls to action.



	How about writing a few awesome case studies with individual screenshots of your favourite work, and creating a portfolio that plays to your strengths? Don’t just rely on the pretty pictures; use your words. Otherwise no-one understands why things are the way they are on that screenshot and BAM! you’ll be judged on someone else’s tastes. (Elliot has a head start on you for this, so get to it!)



	Do you have a serious archive of content? What’s it like being a first-time visitor to your site? Could you write them a guide to introduce yourself and some of the most popular stuff on your site? Ali Edwards is a massively popular crafter and every day she gets new visitors who have found her multiple papercraft projects on Flickr, Vimeo and elsewhere, so she created a welcome guide just for them.



	What about your microcopy? Can you improve on your blogging platform’s defaults for search, comment submission and labels? I’ll bet you can.



	Maybe you could plan a collaboration with other like-minded souls. A week of posts about the more advanced wonders of HTML5 video. A month-long baton-passing exercise in extolling the virtues of IE (shut up, it could happen!). Just spare me any more online advent calendars.



	Watch David McCandless’s TED talk on his jawdropping infographic work and make something as awesome as the Billion Dollar O Gram. I dare you.


Bonus gift: Grab a copy of Brian Suda’s Designing with Data, in print or PDF if Santa didn’t put one in your stocking, and make that awesome something with some expert guidance.

On the eleventh day of Contentmas, Relly gave to me:

11. Pixels pushing

Oh, go on then. Make a gorgeous bespoke velvet-lined container for all that lovely content. It’s proper informed design now, not just decoration. Mr. Zeldman says so.

Bonus gift: I made you a movie! If books were designed like websites.

On the twelfth day of Contentmas, Relly gave to me:

12. Delighters delighting

The Epiphany is upon us; your site is now well on its way to being a beautiful, sustainable hub of content and you have a date in your calendar to help you keep that resolution of blogging more. What now?


	Keep on top of your inventory. One day it will save your butt, I promise.
	Keep making a little bit of time regularly to create something new: an article; an opinion piece; a small curation of related links; a photo diary; a new case study. That’s easier than an annual content bootcamp for sure.
	And today’s gift: look for ways to play with that content and make something a bit special. Stretch yourself a little. It’ll be worth it.


Bonus gift: Paul Annett’s presentation on Ooh, that’s clever: Delighters in design from SxSW 09.

All my favourite designers and developers have their own unique styles and touches. It’s what sets them apart. My very, very favourites have an eloquence and expression that they bring to their sites and to their projects. I absolutely love to explore a well-crafted, well-written site – don’t we all? I know the time it takes. I appreciate the time it takes. But the end results are delicious. Do please share your spangly, refreshed sites with me in the comments.

Catch me on Twitter, I’m @RellyAB, and I’ve been your host for these Twelve Days of Contentmas.",2010,Relly Annett-Baker,rellyannettbaker,2010-12-21T00:00:00+00:00,https://24ways.org/2010/a-contentmas-epiphany/,content
181,Working With RGBA Colour,"When Tim and I were discussing the redesign of this site last year, one of the clear goals was to have a graphical style without making the pages heavy with a lot of images. When we launched, a lot of people were surprised that the design wasn’t built with PNGs. Instead we’d used RGBA colour values, which is part of the CSS3 specification.

What is RGBA Colour?

We’re all familiar with specifying colours in CSS using by defining the mix of red, green and blue light required to achieve our tone. This is fine and dandy, but whatever values we specify have one thing in common — the colours are all solid, flat, and well, a bit boring.

 Flat RGB colours

CSS3 introduces a couple of new ways to specify colours, and one of those is RGBA. The A stands for Alpha, which refers to the level of opacity of the colour, or to put it another way, the amount of transparency. This means that we can set not only the red, green and blue values, but also control how much of what’s behind the colour shows through. Like with layers in Photoshop.

Don’t We Have Opacity Already?

The ability to set the opacity on a colour differs subtly from setting the opacity on an element using the CSS opacity property. Let’s look at an example.

Here we have an H1 with foreground and background colours set against a page with a patterned background.

 Heading with no transparency applied

h1 {
	color: rgb(0, 0, 0);
	background-color: rgb(255, 255, 255);
}

By setting the CSS opacity property, we can adjust the transparency of the entire element and its contents:

 Heading with 50% opacity on the element

h1 {
	color: rgb(0, 0, 0);
	background-color: rgb(255, 255, 255);
	opacity: 0.5;
}

RGBA colour gives us something different – the ability to control the opacity of the individual colours rather than the entire element. So we can set the opacity on just the background:

 50% opacity on just the background colour

h1 {
	color: rgb(0, 0, 0);
	background-color: rgba(255, 255, 255, 0.5);
}

Or leave the background solid and change the opacity on just the text:

 50% opacity on just the foreground colour

h1 {
	color: rgba(0, 0, 0, 0.5);
	background-color: rgb(255, 255, 255);
}

The How-To

You’ll notice that above I’ve been using the rgb() syntax for specifying colours. This is a bit less common than the usual hex codes (like #FFF) but it makes sense when starting to use RGBA. As there’s no way to specify opacity with hex codes, we use rgba() like so:

color: rgba(255, 255, 255, 0.5);

Just like rgb() the first three values are red, green and blue. You can specify these 0-255 or 0%-100%. The fourth value is the opacity level from 0 (completely transparent) to 1 (completely opaque).

You can use this anywhere you’d normally set a colour in CSS — so it’s good for foregrounds and background, borders, outlines and so on. All the transparency effects on this site’s current design are achieved this way.

Supporting All Browsers

Like a lot of the features we’ll be looking at in this year’s 24 ways, RGBA colour is supported by a lot of the newest browsers, but not the rest. Firefox, Safari, Chrome and Opera browsers all support RGBA, but Internet Explorer does not.

Fortunately, due to the robust design of CSS as a language, we can specify RGBA colours for browsers that support it and an alternative for browsers that do not.

Falling back to solid colour

The simplest technique is to allow the browser to fall back to using a solid colour when opacity isn’t available. The CSS parsing rules specify that any unrecognised value should be ignored. We can make use of this because a browser without RGBA support will treat a colour value specified with rgba() as unrecognised and discard it.

So if we specify the colour first using rgb() for all browsers, we can then overwrite it with an rgba() colour for browsers that understand RGBA.

h1 {
	color: rgb(127, 127, 127);
	color: rgba(0, 0, 0, 0.5);
}

Falling back to a PNG

In cases where you’re using transparency on a background-color (although not on borders or text) it’s possible to fall back to using a PNG with alpha channel to get the same effect. This is less flexible than using CSS as you’ll need to create a new PNG for each level of transparency required, but it can be a useful solution.

Using the same principal as before, we can specify the background in a style that all browsers will understand, and then overwrite it in a way that browsers without RGBA support will ignore.

h1 {
	background: transparent url(black50.png);
	background: rgba(0, 0, 0, 0.5) none;
}

It’s important to note that this works because we’re using the background shorthand property, enabling us to set both the background colour and background image in a single declaration. It’s this that enables us to rely on the browser ignoring the second declaration when it encounters the unknown rgba() value.

Next Steps

The really great thing about RGBA colour is that it gives us the ability to create far more graphically rich designs without the need to use images. Not only does that make for faster and lighter pages, but sites which are easier and quicker to build and maintain. CSS values can also be changed in response to user interaction or even manipulated with JavaScript in a way that’s just not so easy using images.

 Opacity can be changed on :hover or manipulated with JavaScript

div {
	color: rgba(255, 255, 255, 0.8);
	background-color: rgba(142, 213, 87, 0.3);
}
div:hover {
	color: rgba(255, 255, 255, 1);
	background-color: rgba(142, 213, 87, 0.6);
}

Clever use of transparency in border colours can help ease the transition between overlay items and the page behind.

 Borders can receive the RGBA treatment, too

div {
	color: rgb(0, 0, 0);
	background-color: rgb(255, 255, 255);
	border: 10px solid rgba(255, 255, 255, 0.3);
}

In Conclusion


That’s a brief insight into RGBA colour, what it’s good for and how it can be used whilst providing support for older browsers. With the current lack of support in Internet Explorer, it’s probably not a technique that commercial designs will want to heavily rely on right away – simply because of the overhead of needing to think about fallback all the time. 

It is, however, a useful tool to have for those smaller, less critical touches that can really help to finesse a design. As browser support becomes more mainstream, you’ll already be familiar and practised with RGBA and ready to go.",2009,Drew McLellan,drewmclellan,2009-12-01T00:00:00+00:00,https://24ways.org/2009/working-with-rgba-colour/,code
176,What makes a website successful? It might not be what you expect!,"What makes some sites succeed and others fail? Put another way, when you are asked to redesign an existing website, what problems are you looking out for and where do you concentrate your efforts?

I would argue that as web designers we spend too much time looking at the wrong kind of problem.

I recently ran a free open door consultancy clinic to celebrate the launch of my new book (yes I know, two shameless plugs in one sentence). This involved various website owners volunteering their sites for review. Both myself and the audience then provided feedback.

What quickly became apparent is that the feedback being given by the audience was biased towards design and development.

Although their comments were excellent it focused almost exclusively on the quality of code, site aesthetics and usability. To address these issues in isolation is similar to treating symptoms and ignoring the underlying illness.

Cure the illness not the symptoms

Poor design, bad usability and terribly written code are symptoms of bigger problems. Often when we endeavour to address these symptoms, we meet resistance from our clients and become frustrated. This is because our clients are still struggling with fundamental concepts we take for granted.

Before we can address issues of aesthetics, usability and code, we need to tackle business objectives, calls to action and user tasks. Without dealing with these fundamental principles our clients’ website will fail.

Let me address each in turn:

Understand the business objectives

Do you ask your clients why they have a website? It feels like an obvious question. However, it is surprising how many clients do not have an answer.

Without having a clear idea of the siteʼs business objectives, the client has no way to know whether it is succeeding. This means they have no justification for further investment and that leads to quibbling over every penny.

However most importantly, without clearly defined business aims they have no standard against which to base their decisions. Everything becomes subjective and that will inevitably lead to problems.

Before we start discussing design, usability and development, we need to focus our clients on establishing concrete business objectives. This will provide a framework for decision making during the development phase.

This will not only help the client make decisions, it will also focus them on the business and away from micro managing the design.

Establish clear calls to action

Once business objectives have been set this opens up the possibility to establish clear calls to action.

I am amazed at how few website owners can name their calls to action. However, I am even more staggered at how few web designers ask about them.

Calls to action are not just limited to ecommerce sites. Whether you are asking people to sign up for a newsletter or complete a contact us form, every site should have a desired objective for users.

What is more, each page of a site should have micro calls to action that always draw users on and never leave them at a dead end.

Without clearly defined calls to action you cannot successfully design a site, structure the user experience or measure its success. They bring focus to the site and encourage the client to concentrate their efforts on helping people reach those goals.

Of course in order to know if a call to action is going to work, it is necessary to do some user testing.

Test against the right tasks

As web designers we all like to boast about being ʻuser centricʼ whatever that means! However, in reality I think many of us are paying lip service to the subject.

Sure, we ask our clients about who their users are and maybe even do some usability testing. However, usability testing is no good if we are not asking the right questions.

Again we find ourselves working on a superficial level rather than tackling the deeper issues.

Clients find it relatively easy to tell you who their target audience is. Admittedly the list they come back with is often overly long and contains a lot of edge cases. However, where they begin to struggle is articulating what these users will want to achieve on the website. They know who they want to reach. However, they cannot always tell you why those people would be interested in the site.

These user tasks are another fundamental building block for any successful website. Although it is important for a website owner to understand what their objectives are and what they want users to do, it is even more important that they understand the users objectives as well.

Again, this provides context for the decisions they are making about design, usability and functionality. Without it the site will become self serving, largely ignoring the needs of users.

User tasks help to focus the clientʼs mind on the needs of their user, rather than what they can get out of them.

So am I claiming that design, usability and code do not matter? Well the shocking truth is that to some extent I am!

The shocking truth

Whether we like it or not there is significant evidence that you can create a successful website with bad design, terrible code and without ever running a usability test session.

You only need to look at the design of Craigslist or the code of Amazon to see that this is true.

However, I do not believe it is possible to build a successful website without business objectives, calls to action and a clear idea of user tasks.

Do not misunderstand me. I do believe design, usability and code matters. I just believe that they only matter if the fundamentals are already in place. These things improve a solid foundation but are no use in their own right.

As web designers it is our responsibility to ensure fundamental questions are being asked, before we start exploring other issues. If we do not, our websites will look great, be well coded and have gone through endless usability tests, however it will not be truly successful.",2009,Paul Boag,paulboag,2009-12-04T00:00:00+00:00,https://24ways.org/2009/what-makes-a-website-successful/,business
174,Type-Inspired Interfaces,"One of the things that terrifies me most about a new project is the starting point. How is the content laid out? What colors do I pick? Once things like that are decided, it becomes significantly easier to continue design, but it’s the blank page where I spend the most time.

To that end, I often start by choosing type. I don’t need to worry about colors or layout or anything else… just the right typefaces that support the art direction. (This article won’t focus on how to choose a typeface, but there are some really great resources if you interested in that sort of thing.)

And just like that, all your work is done. “Hold it just a second,” you might say. “All I’ve done is pick type. I still have to do the rest!”

To which I would reply, “Silly rabbit. You already have!” You see, picking the right typeface gets you farther than you might think. Here are a few tips on taking cues from type to design interfaces and interface elements.

Perfecting Web 2.0

If you’re going for that beloved rounded corner look, you might class it up a bit by choosing the wonderful Omnes Pro by Joshua Darden. As the typeface already has a rounded aesthetic, making buttons that fit the style should be pretty easy.

I’ve found that using multiples helps to keep your interfaces looking balanced and proportional. Noticing that the top left edge of the letter “P” has about an 12px corner radius, let’s choose a 24px radius for our button (a multiple of 2), so that we get proper rounded corners. By taking mathematical measurements from the typeface, our button looks more thought out than just “place arbitrary text on arbitrarily-sized button.” Pretty easy, eh?



What’s in a name(plate)?

Rounded buttons are pretty popular buttons nowadays, so let’s try something a bit more stylized.

Have a gander at Brothers, a sturdy face from Emigre. The chiseled edges give us a perfect cue for a stylized button. Using the same slope, you can make plated-looking buttons that fit a different kind of style.



Headlining

You might even take some cues from the style of the typeface itself. Didone serifs are known for their lack of bracketsーthat is, a gradual transition from the stem to the serif. Instead, they typically connect at a right angle. Another common characteristic is the high contrast in the strokes: very thick stems, very thin serifs.

So, when using a high contrast typeface, you can use it to your advantage to enhance hierarchy. Following our “multiples” guideline, a 12px measurement from the stems helps us create a top rule with a height of 24px (a multiple of 2). We can take the exact 1px measurement from the serif—a multiple of 1—to create the bottom rule. Voilà! I use this technique a lot.



Swashbucklers

And don’t forget the importance of visual “speed bumps” to break up long passages of text. A beautiful face like Alejandro Paul’s Ministry Script has over a thousand characters that can be manipulated or even combined to create elegant interface elements. Altering the partial differential character (∂) creates a delightful ornament that can help to guide the eye through content.



Stagger & Swagger

What about layout? How can we use typography to inform how our content is displayed?

Let’s take a typeface like Assembler. We might use this for a design that needs to feel uneasy or uncomfortable. In design terms, that might translate into using irregular shapes and asymmetry. Using the proportional distances and degrees from the perpendiculars, we could easily create a multi-column layout that jives with the general tone. And for all you skeptics that don’t think a layout like this is doable on the web, stranger things have happened.

 Background texture generously offered by Bittbox.

Overall Design Direction

Finally, your typography could impact the entire look of the site, from the navigation to the interaction and everything in between. Check out how the (now-defunct) Nike Free site’s typography echoes the product itself, and in turn influences the navigation.



Find Your Type

With thousands of fonts to choose from, the possibilities are ridiculously open. From angles to radii to color to weight, you’ve got endless fodder before you. Great type designers spent countless hours slaving over these detailed letterforms; take advantage of it! Don’t feel like you have to limit yourself to the same old Helvetica and wet floors… unless your design calls for it.

186,The Web Is Your CMS,"It is amazing what you can do these days with the services offered on the web. Flickr stores terabytes of photos for us and converts them automatically to all kind of sizes, finds people in them and even allows us to edit them online. YouTube does almost the same complete job with videos, LinkedIn allows us to maintain our CV, Delicious our bookmarks and so on.

We don’t have to do these tasks ourselves any more, as all of these systems also come with ways to use the data in the form of Application Programming Interfaces, or APIs for short. APIs give us raw data when we send requests telling the system what we want to get back.

The problem is that every API has a different idea of what is a simple way of accessing this data and in which format to give it back.

Making it easier to access APIs

What we need is a way to abstract the pains of different data formats and authentication formats away from the developer — and this is the purpose of the Yahoo Query Language, or YQL for short. 

Libraries like jQuery and YUI make it easy and reliable to use JavaScript in browsers (yes, even IE6) and YQL allows us to access web services and even the data embedded in web documents in a simple fashion – SQL style.

Select * from the web and filter it the way I want

YQL is a web service that takes a few inputs itself:


	A query that tells it what to get, update or access
	An output format – XML, JSON, JSON-P or JSON-P-X
	A callback function (if you defined JSON-P or JSON-P-X)


You can try it out yourself – check out this link to get back Flickr photos for the search term ‘santa’*%20from%20flickr.photos.search%20where%20text%3D%22santa%22&format=xml in XML format. The YQL query for this is 

select * from flickr.photos.search where text=""santa""

The easiest way to take your first steps with YQL is to look at the console. There you get sample queries, access to all the data sources available to you and you can easily put together complex queries. In this article, however, let’s use PHP to put together a web page that pulls in Flickr photos, blog posts, Videos from YouTube and latest bookmarks from Delicious.

What we are doing here is create a few different YQL statements and queue them together with the query.multi table. Each of these can be run inside YQL itself. Check out the YouTube, Flickr, Delicious and Blog example in the console if you don’t believe me. The benefit of using this table is that we don’t make individual requests for each query but we get all the data in one single request – which means a much better performing solution as the YQL server farm is faster on the web than our servers.

We point the query to the YQL web service end point and get the resulting data using cURL. All that we need to do then is to convert the returned data to HTML lists that can be printed out inside an HTML template.

Mixing, matching and using HTML as a data source

This was a simple example of what YQL can do for you. Where it gets really powerful however is by mixing and matching different APIs. YQL is also a good tool to get information from HTML documents. By using the html table you can load the content of an HTML document (which gets fixed automatically by HTMLTidy) and use XPATH to filter down results to what you need. Take the following example which takes headlines from the news.bbc.co.uk homepage and runs the results through Yahoo’s Term Extractor API to give you a list of currently hot topics.

select * from search.termextract where context in (
  select content from html where url=""http://news.bbc.co.uk"" and xpath=""//table[@width=800]//a""
)

Try it out in the console or see the results here. In English, this means:


	Go to http://news.bbc.co.uk and get me the HTML
	Run it through HTML Tidy to clean it up.
	Get me only the links inside the table with an attribute of width and the value 800
	Get only the content of the link and for each of the links
	
		Take the content and send it as context to the Yahoo Term Extractor API
	
	

If we choose JSON-P as the output format we can use the outcome directly in JavaScript (see this demo or see its source):

<ul id=""hottopics""></ul>
<script type=""text/javascript"">
function hottopics(o){
  var res = o.query.results.Result,
	  all = res.length,
	  topics = {},
	  out = [],
	  html = '',
	  i=0;
  /* create hash from topics to prevent repetition */	 
  for(i=0;i<all;i++){
	topics[res[i]] = res[i];
  };
  for(i in topics){
	out.push(i);
  };
  html = '<li>' + out.join('</li><li>') + '</li>';
  document.getElementById('hottopics').innerHTML = html;
};
</script>
<script type=""text/javascript"" src=""http://query.yahooapis.com/v1/public/yql?q=select%20content%20from%20search.termextract%20where %20context%20in%20(select%20content%20from%20html%20where%20url%3D%22http%3A%2F%2Fnews.bbc.co.uk%22%20and%20xpath%3D%22%2F%2Ftable%5B%40width%3D800%5D%2F%2Fa%22)&format=json&callback=hottopics""></script>

Using JSON, we can also use PHP which means the demo works for everybody – not only those with JavaScript enabled (see this demo or see its source):

<ul id=""hottopics""><li>
<?php
$url = 'http://query.yahooapis.com/v1/public/yql?q=select%20content'.
	   '%20from%20search.termextract%20where%20context%20in'.
	   '%20(select%20content%20from%20html%20where%20url%3D%22'.
	   'http%3A%2F%2Fnews.bbc.co.uk%22%20and%20xpath%3D%22%2F%2F'.
	   'table%5B%40width%3D800%5D%2F%2Fa%22)&format=json';
$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, $url); 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
$output = curl_exec($ch); 
curl_close($ch);
$data = json_decode($output);
$topics = array_unique($data->query->results->Result);
echo join('</li><li>',$topics);
?>
</li></ul>

Summary

This article could only scratch the surface of YQL. You have not only read access to the web but you can also write to web services. For example you can update Twitter, post to your WordPress blog or shorten a URL with bit.ly. Using Open Tables you can add any web service to the YQL interface and you can even run server-side JavaScript which is for example useful to return Flickr photos as HTML or get the HTML content from a document that needs POST data.

The web of data is already here, and using YQL you don’t have to be a web services expert to use it and be part of it.",2009,Christian Heilmann,chrisheilmann,2009-12-17T00:00:00+00:00,https://24ways.org/2009/the-web-is-your-cms/,code
172,The Construction of Instruction,"If the world were made to my specifications, all your clients would be happy to pay for a web writer to craft every sentence into something as elegant as it was functional, and the client would have planned the content so that you had it just when you asked, but we both know that won’t happen every time. Sometimes you just know they are going to write the About page, two company blog pages and a Facebook fan page before resigning their position as chief content writer and you are going to end up filling in all the details that will otherwise just be Lorem Ipsum.

Welcome to the big world of microcopy:


	A man walks into a bar. The bartender nods a greeting and watches as the man scans the bottles behind the bar. 
“Er, you have a lot of gin here. Is there one you would recommend?” 
“Yes sir.”
Long pause. 
“… Never mind, I’ll have the one in the green bottle.” 
“Certainly, sir. But you can’t buy it from this part of the bar. You need to go through the double doors there.” 
“But they look like they lead into the kitchen.” 
“Really, sir? Well, no, that’s where we allow customers to purchase gin.” 
The man walks through the doors. On the other side he is greeted by the same bartender. 
“Y-you!” he stammers but the reticent bartender is now all but silent. 
Unnerved, the man points to a green bottle, “Er, I’d like to buy a shot of that please. With ice and tonic water.” 
The bartender mixes the drink and puts it on the bar just out of the reach of the man and looks up. 
“Um, do you take cards?” the man asks, ready to present his credit card. 
The bartender goes to take the card to put it through the machine. 
“Wait! How much was it – with sales tax and everything? Do you take a gratuity?” 
The bartender simply shrugs. 
The man eyes him for a moment and decides to try his luck at the bar next door.


In the Choose Your Own Adventure version of this story there are plenty of ways to stop the man giving up. You could let him buy the gin right where he was; you could make the price more obvious; you could signpost the place to buy gin. The mistakes made by the bar and bartender are painfully obvious. And yet, there are websites losing users everyday due to the same lack of clear instruction.

A smidgen of well written copy goes a long way to reassure the nervous prospect. Just imagine if our man walked into the bar and the bartender explained that although the bar was here, sales were conducted in the next room because people were not then able to overhear the man’s card details. Instead, he is left to fend for himself. Online, we kick customers through the anonymous double doors with a merry ‘Paypal will handle your transaction!’.

Recently I worked on a site where the default error message, to account for anything happening that the developers hadn’t accounted for, was ‘SOMETHING HAS GONE WRONG!’. It might have been technically accurate but this is not how to inspire confidence in your customers that they can make a successful purchase through you. As everyone knows they can shop just fine, thank you very much, it is your site they will blame. Card declined? It’s the site. Didn’t know my email address has changed? It’s the site. Can’t log in? It’s the site.

Yes, yes. I know. None of these things are related to your site, or you the developer, but drop outs will be high and you’ll get imploring emails from your client asking you to wade knee deep into the site analytics to find a solution by testing 41 shades of blue because if it worked for Google…? Before you try a visual fix involving the Dulux paint chart breeding with a Pantone swatch, take an objective look at the information you are giving customers. How much are you assuming they know? How much are you relying on age-old labels and prompts without clarification?

Here’s a fun example for non-North Americans: ask your Granny to write out her billing address. If she looks at you blankly, tell her it is the address where the bank sends her statements. Imagine how many fewer instances of the wrong address there would be if we routinely added that information when people purchased from the UK? Instead, we rely on a language convention that hasn’t much common usage without explanation because, well, because we always have since the banks told us how we could take payments online.

So. Your client is busying themselves with writing the ultimate Facebook fan page about themselves and here you are left with creating a cohesive signup process or basket or purchase instructions. Here are five simple rules for bending puny humans to your will creating instructive instructions and constructive error messages that ultimately mean less hassle for you.

Plan what you want to say and plan it out as early as possible 

This goes for all content. Walk a virtual mile in the shoes of your users. What specific help can you offer customers to actively encourage continuation and ensure a minimal amount of dropouts? Make space for that information. One of the most common web content mistakes is jamming too much into a space that has been defined by physical boundaries rather than planned out. If you manage it, the best you can hope for is that no-one notices it was a last-minute job. Mostly it reads like a bad game of Tetris with content sticking out all over the place.

Use your words

Microcopy often says a lot in a few words but without those words you could leave room for doubt. When doubt creeps in a customer wants reassurance just like Alice:


	This time (Alice) found a little bottle… with the words ‘DRINK ME’ beautifully printed on it in large letters. It was all very well to say ‘Drink me,’ but the wise little Alice was not going to do that in a hurry. ‘No, I’ll look first,’ she said, ‘and see whether it’s marked “poison” or not’


Alice in Wonderland, Lewis Carroll.

Value clarity over brevity. Or a little more prosaically, “If in doubt, spell it out.” Thanks, Jeremy!

Be prepared to help


	‘Login failed: email/password combination is incorrect.’


Oh.


	‘Login failed: email/password combination is incorrect. 
Are you typing in all capitals? Caps Lock may be on. 
Have you changed your email address recently and not updated your account with us? Try your old email address first. 
Can’t remember your password? We can help you reset it.’ 


Ah!

Be direct and be informative

There is rarely a site that doesn’t suffer from some degree of jargon. Squash it early by setting a few guidelines about what language and tone of voice you will use to converse with your users. Be consistent. Equally, try to be as specific as possible when giving error messages or instructions and allay fears upfront.

Combine copy and visual cues, learn from others and test new combinations

While visual design and copy can work independently, they work best together. New phrases and designs are being tested all the time so take a peek at abtests.com for more ideas, then test some new ideas and add your own results. Have a look at the microcopy pool on Flickr for some wonderful examples of little words and pictures working together. And yes, you absolutely should join the group and post more examples.


	A man walks into a bar. The bartender greets him in a friendly manner and asks him what he would like to drink. 
“Gin and Tonic, please.” 
“Yes sir, we have our house gin on offer but we also have a particularly good import here too.”
“The import, please.” 
“How would you like it? With a slice of lemon? Over ice?” 
“Both” 
“That’s £3.80. We accept cash, cards or you could open a tab.” 
“Card please.” 
“Certainly sir. Move just over here so that you can’t be observed. Now, please enter your pin number.” 
“Thank you.” 
“And here is your drink. Do let me know if there is a problem with it. I shall just be here at the bar. Enjoy.”

184,Spruce It Up,"The landscape of web typography is changing quickly these days. We’ve gone from the wild west days of sIFR to Cufón to finally seeing font embedding seeing wide spread adoption by browser developers (and soon web designers) with @font-face. For those who’ve felt limited by the typographic possibilities before, this has been a good year.

As Mark Boulton has so eloquently elucidated, @font-face embedding doesn’t come without its drawbacks. Font files can be quite large and FOUT—that nasty flash of unstyled text—can be a distraction for users.

Data URIs

We can battle FOUT by using Data URIs. A Data URI allows the font to be encoded right into the CSS file. When the font comes with the CSS, the flash of unstyled text is mitigated. No extra HTTP requests are required. 

Don’t be a grinch, though. Sending hundreds of kilobytes down the pipe still isn’t great. Sometimes, all we want to do is spruce up our site with a little typographic sugar. 

Be Selective

Dan Cederholm’s SimpleBits is an attractive site. 



Take a look at the ampersand within the header of his site. It’s the lovely (and free) Goudy Bookletter 1911 available from The League of Movable Type. The Opentype format is a respectable 28KB. Nothing too crazy but hold on here. Mr. Cederholm is only using the ampersand! Ouch. That’s a lot of bandwidth just for one character.

Can we optimize a font like we can an image? Yes. Image optimization essentially works by removing unnecessary image data such as colour data, hidden comments or using compression algorithms. How do you remove unnecessary information from a font? Subsetting. 

If you’re the adventurous type, grab a copy of FontForge, which is an open source font editing tool. You can open the font, view and edit any of the glyphs and then re-generate the font. The interface is a little clunky but you’ll be able to select any character you don’t want and then cut the glyphs. Re-generate your font and you’ve now got a smaller file. 



There are certainly more optimizations that can also be made such as removing hinting and kerning information. Keep in mind that removing this information may affect how well the type renders.

At this time of year, though, I’m sure you’re quite busy. Save yourself some time and head on over to the Font Squirrel Font Generator.



The Font Generator is extremely handy and allows for a number of optimizations and cross-platform options to be generated instantly. Select the font from your local system—make sure that you are only using properly licensed fonts! 

In this particular case, we only want the ampersand. Click on Subset Fonts which will open up a new menu. Unselect any preselected sets and enter the ampersand into the Single Characters text box. 

Generate your font and what are you left with? 3KB. 



The Font Generator even generates a base64 encoded data URI stylesheet to be imported easily into your project.

Check out the Demo page. (This demo won’t work in Internet Explorer as we’re only demonstrating the Data URI font embedding and not using the EOT file format that IE requires.) 

No Unnecessary Additives

If you peeked under the hood of that demo, did you notice something interesting? There’s no <span> around the ampersand. The great thing about this is that we can take advantage of the font stack’s natural ability to switch to a fallback font when a character isn’t available.

Just like that, we’ve managed to spruce up our page with a little typographic sugar without having to put on too much weight.",2009,Jonathan Snook,jonathansnook,2009-12-19T00:00:00+00:00,https://24ways.org/2009/spruce-it-up/,code
190,Self-Testing Pages with JavaScript,"Working at an agency I am involved more and more on projects in which client side code is developed internally then sent out to a separate team for implementation. You provide static HTML, CSS and JavaScript which then get placed into the CMS and brought to life as an actual website. As you can imagine this can sometimes lead to frustrations. However many safeguards you include, handing over your code to someone else is always a difficult thing to do effectively.

In this article I will show you how you can create a JavaScript implementation checker and that will give you more time for drink based activity as your web site and apps are launched quicker and with less unwanted drama!

An all too frequent occurrence

You’ve been working on a project for weeks, fixed all your bugs and send it to be implemented. You hear nothing and assume all is going well then a few days before it’s meant to launch you get an email from the implementation team informing you of bugs in your code that you need to urgently fix.

 The 24ways website with a misspelt ID for the years menu

Being paranoid you trawl through the preview URL, check they have the latest files, check your code for errors then notice that a required HTML attribute has been omitted from the build and therefore CSS or JavaScript you’ve hooked onto that particular attribute isn’t being applied and that’s what is causing the “bug”.

It takes you seconds drafting an email informing them of this, it takes then seconds putting the required attribute in and low and behold the bug is fixed, everyone is happy but you’ve lost a good few hours of your life – this time could have been better spent in the pub.

I’m going to show you a way that these kind of errors can be alerted immediately during implementation of your code and ensure that when you are contacted you know that there actually is a bug to fix. You probably already know the things that could be omitted from a build and look like bugs so you’ll soon be creating tests to look for these and alert when they are not found on the rendered page. The error is reported directly to those who need to know about it and fix it. Less errant bug reports and less frantic emails ahoy!

 A page with an implementation issue and instant feedback on the problem

JavaScript selector engines to the rescue

Whether you’re using a library or indeed tapping into the loveliness of the new JavaScript Selector APIs looking for particular HTML elements in JavaScript is fairly trivial now. 

For instance this is how you look for a div element with the id attribute of year (the missing attribute from top image) using jQuery (the library I’ll be coding my examples in): 

if ($(‘div#year’).length) {
	alert(‘win’);
}

Using this logic you can probably imagine how you can write up a quick method to check for the existence of a particular element and alert when it’s not present — but assuming you have a complex page you’re going to be repeating yourself a fair bit and we don’t want to be doing that.

Test scripts

If you’ve got a lot of complex HTML patterns that need testing across a number of different pages it makes sense to keep your tests out of production code. Chances are you’ve already got a load of heavy JavaScript assets, and when it comes to file size saving every little helps.

I don’t think that tests should contain code inside of them so keep mine externally as JSON. This also means that you can use the one set of tests in multiple places. We already know that it’s a good idea to keep our CSS and JavaScript separate so lets continue along those lines here.

The test script for this example looks like this:

{
	""title"": ""JS tabs implementation test"",
	""description"": ""Check that the correct HTML patterns has been used"",
	""author"": ""Ross Bruniges"",
	""created"": ""20th July 2009"",
	""tests"": [
		{
			""name"": ""JS tabs elements"",
			""description"": ""Checking that correct HTML elements including class/IDs are used on the page for the JS to progressively enhance"",
			""selector"": ""div.tabbed_content"",
			""message"": ""We couldn't find VAR on the page - it's required for our JavaScript to function correctly"",
			""check_for"": {
				""contains"": {
					""elements"": [
						""div.tab_content"", ""h2"" 
					],
					""message"": ""We've noticed some missing HTML:</p><ul><li>VAR</li></ul><p>please refer to the examples sent for reference"" 
				} 
			} 
		} 
	]
}

The first four lines are just a little bit of meta data so we remember what this test was all about when we look at it again in the future, or indeed if it ever breaks. The tests are the really cool parts and firstly you’ll notice that it’s an array – we’re only going to show one example test here but there is no reason why you can’t place in as many as you want. I’ll explain what each of the lines in the example test means:


	name – short test name, I use this in pass/fail messaging later
	description – meta data for future reference
	selector – the root HTML element from which your HTML will be searched
	message – what the app will alert if the initial selector isn’t found
	check_for – a wrapper to hold inner tests – those run if the initial selector does match
	
		contains – the type of check, we’re checking that the selector contains specified elements
		
			elements – the HTML elements we are searching for
			message – a message for when these don’t match (VAR is substituted when it’s appended to the page with the name of any elements that don’t exist)
		
		
		

It’s very important to pass the function valid JSON (JSONLint is a great tool for this) otherwise you might get a console showing no tests have even been run. 

The JavaScript that makes this helpful

Again, this code should never hit a production server so I’ve kept it external. This also means that the only thing that’s needed to be done by the implementation team when they are ready to build is that they delete this code.

<script src=""sleuth.js"" type=""text/javascript""></script>
<script type=""text/javascript"">
	$(document).ready(function() {
	  sleuth.test_page.init(‘js_tabs_test.js');
	}); 
</script>

“View the full JavaScript:/examples/self-testing-pages-with-javascript/js/tests/test_suite.js

The init function appends the test console to the page and inserts the CSS file required to style it (you don’t need to use pictures of me when tests pass and fail though I see no reason why you shouldn’t), goes and grabs the JSON file referenced and parses it. The methods to pass (tests_pass) and fail (haz_fail) the test I hope are pretty self-explanatory as is the one which creates the test summary once everything has been run (create_summary).

The two interesting functions are init_tests and confirm_html.

init_tests

init_tests:function(i,obj) {
	var $master_elm = $(obj.selector);
	sleuth.test_page.$logger.append(""<div id='test_"" + i + ""' class='message'><p><em>"" + obj.name + ""</em></p></div>"");
	var $container = $('#test_' + i);
	if (!$master_elm.length) {
		var err_sum = obj.message.replace(/VAR/gi, obj.selector);
		sleuth.test_page.haz_failed(err_sum, $container);
		return;
	}
	if (obj.check_for) {
		$.each(obj.check_for,function(key, value){
			sleuth.test_page.assign_checks($master_elm, $container, key, value);
		});
	} else {
		sleuth.test_page.tests_passed($container);
		return;
	}
}

The function gets sent the number of the current iteration (used to create a unique id for its test summary) and the current object that contains the data we’re testing against as parameters.

We grab a reference to the root element and this is used (pretty much in the example shown right at the start of this article) and its length is checked. If the length is positive we know we can continue to the inner tests (if they exist) but if not we fail the test and don’t go any further. We append the error to the test console for everyone to see.

If we pass the initial check we send the reference to the root element, message contains and the inner object to a function that in this example sends us on to confirm_html (if we had a more complex test suite it would do a lot more). 

confirm_html

confirm_html:function(target_selector, error_elm, obj) {
	var missing_elms = [];
	$.each(obj.elements, function(i, val) {
		if (!target_selector.find(val).length) {
			missing_elms.push(val);
		}	
	});
	if (missing_elms.length) {
		var file_list = missing_elms.join('</li><li>');
		var err_sum = obj.message.replace(/VAR/gi, file_list);
		sleuth.test_page.haz_failed(err_sum, error_elm);
		return;
	}
	sleuth.test_page.tests_passed(error_elm);
	return;
}

We’re again using an array to check for a passed or failed test and checking its length but this time we push in a reference to each missing element we find.

If the test does fail we’re providing even more useful feedback by informing what elements have been missed out. All the implementation team need do is look for them in the files we’ve sent and include them as expected.

No more silly implementation bugs!

Here is an example of a successful implementation.

Here are some examples of failed implementations – one which fails at finding the root node and one that has the correct root node but none of the inner HTML tests pass.

Is this all we can check for?

Certainly not!

JavaScript provides pretty easy ways to check for attributes, included files (if the files being checked for are being referenced correctly and not 404ing) and even applied CSS.

Want to check that those ARIA attributes are being implemented correctly or that all images contain an alt attribute well this simple test suite can be extended to include tests for this – the sky is pretty much up to your imagination.",2009,Ross Bruniges,rossbruniges,2009-12-12T00:00:00+00:00,https://24ways.org/2009/self-testing-pages-with-javascript/,process
171,Rock Solid HTML Emails,"At some stage in your career, it’s likely you’ll be asked by a client to design a HTML email. Before you rush to explain that all the cool kids are using social media, keep in mind that when done correctly, email is still one of the best ways to promote you and your clients online. In fact, a recent survey showed that every dollar spent on email marketing this year generated more than $40 in return. That’s more than any other marketing channel, including the cool ones.

There are a whole host of ingredients that contribute to a good email marketing campaign. Permission, relevance, timeliness and engaging content are all important. Even so, the biggest challenge for designers still remains building an email that renders well across all the popular email clients.

Same same, but different

Before getting into the details, there are some uncomfortable facts that those new to HTML email should be aware of. Building an email is not like building for the web. While web browsers continue their onward march towards standards, many email clients have stubbornly stayed put. Some have even gone backwards. In 2007, Microsoft switched the Outlook rendering engine from Internet Explorer to Word. Yes, as in the word processor. Add to this the quirks of the major web-based email clients like Gmail and Hotmail, sprinkle in a little Lotus Notes and you’ll soon realize how different the email game is.

While it’s not without its challenges, rest assured it can be done. In my experience the key is to focus on three things. First, you should keep it simple. The more complex your email design, the more likely is it to choke on one of the popular clients with poor standards support. Second, you need to take your coding skills back a good decade. That often means nesting tables, bringing CSS inline and following the coding guidelines I’ll outline below. Finally, you need to test your designs regularly. Just because a template looks nice in Hotmail now, doesn’t mean it will next week.

Setting your lowest common denominator

To maintain your sanity, it’s a good idea to decide exactly which email clients you plan on supporting when building a HTML email. While general research is helpful, the email clients your subscribers are using can vary significantly from list to list. If you have the time there are a number of tools that can tell you specifically which email clients your subscribers are using. Trust me, if the testing shows almost none of them are using a client like Lotus Notes, save yourself some frustration and ignore it altogether. 

Knowing which email clients you’re targeting not only makes the building process easier, it can save you lots of time in the testing phase too. For the purpose of this article, I’ll be sharing techniques that give the best results across all of the popular clients, including the notorious ones like Gmail, Lotus Notes 6 and Outlook 2007. Just remember that pixel perfection in all email clients is a pipe dream.

Let’s get started.

Use tables for layout

Because clients like Gmail and Outlook 2007 have poor support for float, margin and padding, you’ll need to use tables as the framework of your email. While nested tables are widely supported, consistent treatment of width, margin and padding within table cells is not. For the best results, keep the following in mind when coding your table structure.

Set the width in each cell, not the table

When you combine table widths, td widths, td padding and CSS padding into an email, the final result is different in almost every email client. The most reliable way to set the width of your table is to set a width for each cell, not for the table itself.

<table cellspacing=""0"" cellpadding=""10"" border=""0"">
	<tr>
		<td width=""80""></td>
		<td width=""280""></td>
	</tr>
</table>

Never assume that if you don’t specify a cell width the email client will figure it out. It won’t.  Also avoid using percentage based widths. Clients like Outlook 2007 don’t respect them, especially for nested tables. Stick to pixels. If you want to add padding to each cell, use either the cellpadding attribute of the table or CSS padding for each cell, but never combine the two.

Err toward nesting

Table nesting is far more reliable than setting left and right margins or padding for table cells. If you can achieve the same effect by table nesting, that will always give you the best result across the buggier email clients.

Use a container table for body background colors

Many email clients ignore background colors specified in your CSS or the <body> tag. To work around this, wrap your entire email with a 100% width table and give that a background color.

<table cellspacing=""0"" cellpadding=""0"" border=""0"" width=""100%"">
	<tr>
		<td bgcolor=”#000000”>
			Your email code goes here.
		</td>
	</tr>
</table>

You can use the same approach for background images too. Just remember that some email clients don’t support them, so always provide a fallback color.

Avoid unnecessary whitespace in table cells

Where possible, avoid whitespace between your <td> tags. Some email clients (ahem, Yahoo! and Hotmail) can add additional padding above or below the cell contents in some scenarios, breaking your design for no apparent reason.

CSS and general font formatting

While some email designers do their best to avoid CSS altogether and rely on the dreaded <font> tag, the truth is many CSS properties are well supported by most email clients. See this comprehensive list of CSS support across the major clients for a good idea of the safe properties and those that should be avoided. 

Always move your CSS inline

Gmail is the culprit for this one. By stripping the CSS from the <head> and <body> of any email, we’re left with no choice but to move all CSS inline. The good news is this is something you can almost completely automate. Free services like Premailer will move all CSS inline with the click of a button. I recommend leaving this step to the end of your build process so you can utilize all the benefits of CSS.

Avoid shorthand for fonts and hex notation

A number of email clients reject CSS shorthand for the font property. For example, never set your font styles like this.

p {
	font:bold 1em/1.2em georgia,times,serif;
}

Instead, declare the properties individually like this.

p {
	font-weight: bold;
	font-size: 1em;
	line-height: 1.2em;
	font-family: georgia,times,serif;
}

While we’re on the topic of fonts, I recently tested every conceivable variation of @font-face across the major email clients. The results were dismal, so unfortunately it’s web-safe fonts in email for the foreseeable future.

When declaring the color property in your CSS, some email clients don’t support shorthand hexadecimal colors like color:#f60; instead of color:#ff6600;. Stick to the longhand approach for the best results.

Paragraphs

Just like table cell spacing, paragraph spacing can be tricky to get a consistent result across the board. I’ve seen many designers revert to using double <br /> or DIVs with inline CSS margins to work around these shortfalls, but recent testing showed that paragraph support is now reliable enough to use in most cases (there was a time when Yahoo! didn’t support the paragraph tag at all).

The best approach is to set the margin inline via CSS for every paragraph in your email, like so:

p {
	margin: 0 0 1.6em 0;
}

Again, do this via CSS in the head when building your email, then use Premailer to bring it inline for each paragraph later.

If part of your design is height-sensitive and calls for pixel perfection, I recommend avoiding paragraphs altogether and setting the text formatting inline in the table cell. You might need to use table nesting or cellpadding / CSS to get the desired result. Here’s an example:

<td width=""200"" style=""font-weight:bold; font-size:1em; line-height:1.2em; font-family:georgia,'times',serif;"">your height sensitive text</td>

Links

Some email clients will overwrite your link colors with their defaults, and you can avoid this by taking two steps. First, set a default color for each link inline like so:

<a href=""http://somesite.com/"" style=""color:#ff00ff"">this is a link</a>

Next, add a redundant span inside the a tag.

<a href=""http://somesite.com/"" style=""color:#ff00ff""><span style=""color:#ff00ff"">this is a link</span></a>

To some this may be overkill, but if link color is important to your design then a superfluous span is the best way to achieve consistency.

Images in HTML emails

The most important thing to remember about images in email is that they won’t be visible by default for many subscribers. If you start your design with that assumption, it forces you to keep things simple and ensure no important content is suppressed by image blocking.

With this in mind, here are the essentials to remember when using images in HTML email:

Avoid spacer images

While the combination of spacer images and nested tables was popular on the web ten years ago, image blocking in many email clients has ruled it out as a reliable technique today. Most clients replace images with an empty placeholder in the same dimensions, others strip the image altogether. Given image blocking is on by default in most email clients, this can lead to a poor first impression for many of your subscribers. Stick to fixed cell widths to keep your formatting in place with or without images.

Always include the dimensions of your image

If you forget to set the dimensions for each image, a number of clients will invent their own sizes when images are blocked and break your layout. Also, ensure that any images are correctly sized before adding them to your email. Some email clients will ignore the dimensions specified in code and rely on the true dimensions of your image. 

Avoid PNGs

Lotus Notes 6 and 7 don’t support 8-bit or 24-bit PNG images, so stick with the GIF or JPG formats for all images, even if it means some additional file size.

Provide fallback colors for background images

Outlook 2007 has no support for background images (aside from this hack to get full page background images working). If you want to use a background image in your design, always provide a background color the email client can fall back on. This solves both the image blocking and Outlook 2007 problem simultaneously.

Don’t forget alt text

Lack of standards support means email clients have long destroyed the chances of a semantic and accessible HTML email. Even still, providing alt text is important from an image blocking perspective. Even with images suppressed by default, many email clients will display the provided alt text instead. Just remember that some email clients like Outlook 2007, Hotmail and Apple Mail don’t support alt text at all when images are blocked.

Use the display hack for Hotmail

For some inexplicable reason, Windows Live Hotmail adds a few pixels of additional padding below images. A workaround is to set the display property like so.

img {display:block;}

This removes the padding in Hotmail and still gives you the predicable result in other email clients.

Don’t use floats

Both Outlook 2007 and earlier versions of Notes offer no support for the float property. Instead, use the align attribute of the img tag to float images in your email.

<img src=""image.jpg"" align=""right"">

If you’re seeing strange image behavior in Yahoo! Mail, adding align=“top” to your images can often solve this problem.

Video in email

With no support for JavaScript or the object tag, video in email (if you can call it that) has long been limited to animated gifs. However, some recent research I did into the HTML5 video tag in email showed some promising results.

Turns out HTML5 video does work in many email clients right now, including Apple Mail, Entourage 2008, MobileMe and the iPhone. The real benefit of this approach is that if the video isn’t supported, you can provide reliable fallback content such as an animated GIF or a clickable image linking to the video in the browser.

Of course, the question of whether you should add video to email is another issue altogether. If you lean toward the “yes” side check out the technique with code samples.

What about mobile email?

The mobile email landscape was a huge mess until recently. With the advent of the iPhone, Android and big improvements from Palm and RIM, it’s becoming less important to think of mobile as a different email platform altogether.

That said, there are a few key pointers to keep in mind when coding your emails to get a decent result for your more mobile subscribers.

Keep the width less than 600 pixels

Because of email client preview panes, this rule was important long before mobile email clients came of age. In truth, the iPhone and Pre have a viewport of 320 pixels, the Droid 480 pixels and the Blackberry models hover around 360 pixels. Sticking to a maximum of 600 pixels wide ensures your design should still be readable when scaled down for each device. This width also gives good results in desktop and web-based preview panes.

Be aware of automatic text resizing

In what is almost always a good feature, email clients using webkit (such as the iPhone, Pre and Android) can automatically adjust font sizes to increase readability. If testing shows this feature is doing more harm than good to your design, you can always disable it with the following CSS rule:

-webkit-text-size-adjust: none;

Don’t forget to test

While standards support in email clients hasn’t made much progress in the last few years, there has been continual change (for better or worse) in some email clients. Web-based providers like Yahoo!, Hotmail and Gmail are notorious for this. On countless occasions I’ve seen a proven design suddenly stop working without explanation.

For this reason alone it’s important to retest your email designs on a regular basis. I find a quick test every month or so does the trick, especially in the web-based clients. The good news is that after designing and testing a few HTML email campaigns, you will find that order will emerge from the chaos. Many of these pitfalls will become quite predictable and your inbox-friendly designs will take shape with them in mind.

Looking ahead

Designing HTML email can be a tough pill for new designers and standardistas to swallow, especially given the fickle and retrospective nature of email clients today. With HTML5 just around the corner we are entering a new, uncertain phase. Will email client developers take the opportunity to repent on past mistakes and bring email clients into the present? The aim of groups such as the Email Standards Project is to make much of the above advice as redundant as the long-forgotten <blink> and <marquee> tags, however, only time will tell if this is to become a reality.

Although not the most compliant (or fashionable) medium, the results speak for themselves – email is, and will continue to be one of the most successful and targeted marketing channels available to you. As a designer with HTML email design skills in your arsenal, you have the opportunity to not only broaden your service offering, but gain a unique appreciation of how vital standards are.

173,Real Fonts and Rendering: The New Elephant in the Room,"My friend, the content strategist Kristina Halvorson, likes to call content “the elephant in the room” of web design. She means it’s the huge problem that no one on the web development team or client side is willing to acknowledge, face squarely, and plan for. 

A typical web project will pass through many helpful phases of research, and numerous beneficial user experience design iterations, while the content—which in most cases is supposed to be the site’s primary focus—gets handled haphazardly at the end. Hence, elephant in the room, and hence also artist Kevin Cornell’s recent use of elephantine imagery to illustrate A List Apart articles on the subject. But I digress.

Without discounting the primacy of the content problem, we web design folk have now birthed ourselves a second lumbering mammoth, thanks to our interest in “real fonts on the web“ (the unfortunate name we’ve chosen for the recent practice of serving web-licensed fonts via CSS’s decade-old @font-face declaration—as if Georgia, Verdana, and Times were somehow unreal). 

For the fact is, even bulletproof and mo’ bulletproofer @font-face CSS syntax aren’t really bulletproof if we care about looks and legibility across browsers and platforms.

Hyenas in the Breakfast Nook

The problem isn’t just that foundries have yet to agree on a standard font format that protects their intellectual property. And that, even when they do, it will be a while before all browsers support that standard—leaving aside the inevitable politics that impede all standardization efforts. Those are problems, but they’re not the elephant. Call them the coyotes in the room, and they’re slowly  being tamed.

Nor is the problem that workable, scalable business models (of which Typekit‘s is the most visible and, so far, the most successful) are still being shaken out and tested. The quality and ease of use of such services, their stability on heavily visited sites (via massively backed-up server clusters), and the fairness and sustainability of their pricing will determine how licensing and serving “real fonts” works in the short and long term for the majority of designer/developers.

Nor is our primary problem that developers with no design background may serve ugly or illegible fonts that take forever to load, or fonts that take a long time to download and then display as ordinary system fonts (as happens on, say, about.validator.nu). Ugliness and poor optimization on the web are nothing new. That support for @font-face in Webkit and Mozilla browsers (and for TrueType fonts converted to Embedded OpenType in Internet Explorer) adds deadly weapons to the non-designer’s toolkit is not the technology’s fault. JavaScript and other essential web technologies are equally susceptible to abuse. 

Beauty is in the Eye of the Rendering Engine

No, the real elephant in the room—the thing few web developers and no “web font” enthusiasts are talking about—has to do with legibility (or lack thereof) and aesthetics (or lack thereof) across browsers and platforms. Put simply, even fonts optimized for web use (which is a whole thing: ask a type designer) will not look good in every browser and OS. That’s because every browser treats hinting differently, as does every OS, and every OS version. 

Firefox does its own thing in both Windows and Mac OS, and Microsoft is all over the place because of its need to support multiple generations of Windows and Cleartype and all kinds of hardware simultaneously. Thus “real type” on a single web page can look markedly different, and sometimes very bad, on different computers at the same company. If that web page is your company’s, your opinion of “web fonts” may suffer, and rightfully. (The advantage of Apple’s closed model, which not everyone likes, is that it allows the company to guarantee the quality and consistency of user experience.)  

As near as my font designer friends and I can make out, Apple’s Webkit in Safari and iPhone ignores hinting and creates its own, which Apple thinks is better, and which many web designers think of as “what real type looks like.” The forked version of Webkit in Chrome, Android, and Palm Pre also creates its own hinting, which is close to iPhone’s—close enough that Apple, Palm, and Google could propose it as a standard for use in all browsers and platforms. Whether Firefox would embrace a theoretical Apple and Google standard is open to conjecture, and I somehow have difficulty imagining Microsoft buying in—even though they know the web is more and more mobile, and that means more and more of their customers are viewing web content in some version of Webkit.

The End of Simple

There are ways around this ugly type ugliness, but they involve complicated scripting and sniffing—the very nightmares from which web standards and the simplicity of @font-face were supposed to save us. I don’t know that even mighty Typekit has figured out every needed variation yet (although, working with foundries, they probably will). 

For type foundries, the complexity and expense of rethinking classic typefaces to survive in these hostile environments may further delay widespread adoption of web fonts and the resolution of licensing and formatting issues. The complexity may also force designers (even those who prefer to own) to rely on a hosted rental model simply to outsource and stay current with the detection and programming required.

Forgive my tears. I stand in a potter’s field of ideas like “Keep it simple,” by a grave whose headstone reads “Write once, publish everywhere.”",2009,Jeffrey Zeldman,jeffreyzeldman,2009-12-22T00:00:00+00:00,https://24ways.org/2009/real-fonts-and-rendering/,design
185,Make Your Mockup in Markup,"We aren’t designing copies of web pages, we’re designing web pages.

	 Andy Clarke, via Quotes on Design


The old way

I used to think the best place to design a website was in an image editor. I’d create a pixel-perfect PSD filled with generic content, send it off to the client, go through several rounds of revisions, and eventually create the markup.

Does this process sound familiar? You’re not alone. In a very scientific and official survey I conducted, close to 90% of respondents said they design in Photoshop before the browser.  

That process is whack, yo!

Recently, thanks in large part to the influence of design hero Dan Cederholm, I’ve come to the conclusion that a website’s design should begin where it’s going to live: in the browser.

Die Photoshop, die

Some of you may be wondering, “what’s so bad about using Photoshop for the bulk of my design?” Well, any seasoned designer will tell you that working in Photoshop is akin to working in a minefield: you never know when it’s going to blow up in your face.

 The application Adobe Photoshop CS4 has unexpectedly ruined your day.

Photoshop’s propensity to crash at crucial moments is a running joke in the industry, as is its barely usable interface. And don’t even get me started on the hot, steaming pile of crap that is  text rendering.

 Text rendered in Photoshop (left) versus Safari (right).

Crashing and text rendering issues suck, but we’ve learned to live with them. The real issue with using Photoshop for mockups is the expectations you’re setting for a client. When you send the client a static image of the design, you’re not giving them the whole picture — they can’t see how a fluid grid would function, how the design will look in a variety of browsers, basic interactions like :hover effects, or JavaScript behaviors. For more on the disadvantages to showing clients designs as images rather than websites, check out Andy Clarke’s Time to stop showing clients static design visuals.

A necessary evil?

In the past we’ve put up with Photoshop because it was vital to achieving our beloved rounded corners, drop shadows, outer glows, and gradients. However, with the recent adaptation of CSS3 in major browsers, and the slow, joyous death of IE6, browsers can render mockups that are just as beautiful as those created in an image editor. With the power of RGBA, text-shadow, box-shadow, border-radius, transparent PNGs, and @font-face combined, you can create a prototype that radiates shiny awesomeness right in the browser. If you can see this epic article through to the end, I’ll show you step by step how to create a gorgeous mockup using mostly markup.

Get started by getting naked 


	Content precedes design. Design in the absence of content is not design, it’s decoration.

	 Jeffrey Zeldman


In the beginning, don’t even think about style. Instead, start with the foundation: the content. Lay the groundwork for your markup order, and ensure that your design will be useable with styles and images turned off. This is great for prioritizing the content, and puts you on the right path for accessibility and search engine optimization. Not a bad place to start, amirite?

 An example of unstyled content, in all its naked glory. View it large.

Flush out the layout 

The next step is to structure the content in a usable way. With CSS, making basic layout changes is as easy as switching up a float, so experiment to see what structure suits the content best.

 The mockup with basic layout work done.

Got your grids covered

There are a variety of tools that allow you to layer a grid over your browser window. For Mac users I recommend using Slammer, and PC users can check out one of the bookmarklets that are available, such as 960 Gridder.

 The mockup with a grid applied using Slammer.

Once you’ve found a layout that works well for the content, pass it along to the client for review. This keeps them involved in the design process, and gives them an idea of how the site will be structured when it’s live.

Start your styling

Now for the fun part: begin applying the presentation layer. Let usability considerations drive your decisions about color and typography; use highlighted colors and contrasting typefaces on elements you wish to emphasize.

RGBA? More like RGByay!

Introducing color is easy with RGBA. I like to start with the page’s main color, then use white at varying opacities to empasize content sections.

 In the example mockup the body background is set to rgba(203,111,21), the content containers are set to rgba(255,255,255,0.7), and a few elements are highlighted with rgba(255,255,255,0.1) If you’re not sure how RGBA works, check out Drew McLellan’s super helpful 24ways article.

Laying down type

Just like with color, you can use typography to evoke a feeling and direct a user’s attention. Have contrasting typefaces (like serif headlines and sans-serif body text) to group the content into meaningful sections.

In a recent A List Apart article, the Master of Web Typography™ Jason Santa Maria offers excellent advice on how to choose your typefaces:


	Write down a general description of the qualities of the message you are trying to convey, and then look for typefaces that embody those qualities.


Sounds pretty straightforward. I wanted to give my design a classic feel with a hint of nostalgia, so I used Georgia for the headlines, and incorporated the ornate ampersand from Baskerville into the header.

 A closeup on the site’s header.

Let’s get sexy

The design doesn’t look too bad as it is, but it’s still pretty flat. We can do better, and after mixing in some CSS3 and a couple of PNGs, it’s going to get downright steamy in here.

Give it some glow

Objects in the natural world reflect light, so to make your design feel tangible and organic, give it some glow. In the example design I achieved this by creating two white to transparent gradients of varying opacities. Both have a solid white border across their top, which gives edges a double border effect and makes them look sharper. Using CSS3’s text-shadow on headlines and box-shadow on content modules is another quick way to add depth.

 A wide and closeup view of the design with gradients, text-shadow and box-shadow added. For information on how to implement text-shadow and box-shadow using RGBA, check out the article I wrote on it last week.


37 pieces of flair

Okay, maybe you don’t need that much flair, but it couldn’t hurt to add a little; it’s the details that will set your design apart. Work in imagery and texture, using PNGs with an alpha channel so you can layer images and still tweak the color later on.

 The design with grungy textures, a noisy diagonal stripe pattern, and some old transportation images layered behind the text. Because the colors are rendered using RGBA, these images bleed through the content, giving the design a layered feel. Best viewed large.


Send it off

Hey, look at that. You’ve got a detailed, well structured mockup for the client to review. Best of all, your markup is complete too. If the client approves the design at this stage, your template is practically finished. Bust out the party hats!

Not so fast, Buster!

So I don’t know about you, but I’ve never gotten a design past the client’s keen eye for criticism on the first go. Let’s review some hypothetical feedback (none of which is too outlandish, in my experience), and see how we’d make the requested changes in the browser. 

Updating the typography


	My ex-girlfriend loved Georgia, so I never want to see it again. Can we get rid of it? I want to use a font that’s chunky and loud, just like my stupid ex-girlfriend.

	 Fakey McClient


Yikes! Thankfully with CSS, removing Georgia is as easy as running a find and replace on the stylesheet. In my revised mockup, I used @font-face and League Gothic on the headlines to give the typography the, um, unique feel the client is looking for.

 The same mockup, using @font-face on the headlines. If you’re unfamiliar with implementing @font-face, check out Nice Web Type‘s helpful article.

Adding rounded corners


	I’m not sure if I’ll like it, but I want to see what it’d look like with rounded corners. My cousin, a Web 2.0 marketing guru, says they’re trendy right now.

	 Fakey McClient


Switching to rounded corners is a nightmare if you’re doing your mockup in Photoshop, since it means recreating most of the shapes and UI elements in the design. Thankfully, with CSS border-radius comes to our rescue! By applying this gem of a style to a handful of classes, you’ll be rounded out in no time.

 The mockup with rounded corners, created using border-radius. If you’re not sure how to implement border-radius, check out CSS3.info‘s quick how-to.

Making changes to the color


	The design is too dark, it’s depressing! They call it ‘the blues’ for a reason, dummy. Can you try using a brighter color? I want orange, like Zeldman uses.

	 Fakey McClient


Making color changes is another groan-inducing task when working in Photoshop. Finding and updating every background layer, every drop shadow, and every link can take forever in a complex PSD. However, if you’ve done your mockup in markup with RGBA and semi-transparent PNGs, making changes to your color is as easy as updating the body background and a few font colors.

 The mockup with an orange color scheme. Best viewed large.

Ahem, what about Internet Explorer?

Gee, thanks for reminding me, buzzkill. Several of the CSS features I’ve suggested you use, such as RGBA, text-shadow and box-shadow, and border-radius, are not supported in Internet Explorer. I know, it makes me sad too. However, this doesn’t mean you can’t try these techniques out in your markup based mockups.  The point here is to get your mockups done as efficiently as possible, and to keep the emphasis on markup from the very beginning.

Once the design is approved, you and the client have to decide if you can live with the design looking different in different browsers. Is it so bad if some users get to see drop shadows and some don’t? Or if the rounded corners are missing for a portion of your audience? The design won’t be broken for IE people, they’re just missing out on a few visual treats that other users will see.

The idea of rewarding users who choose modern browsers is not a new concept; Dan covers it thoroughly in Handcrafted CSS, and it’s been written about in the past by Aaron Gustafson and Andy Clarke on several occasions. I believe we shouldn’t have to design for the lowest common denominator (cough, IE6 users, cough); instead we should create designs that are beautiful in modern browsers, but still degrade nicely for the other guy. However, some clients just aren’t that progressive, and in that case you can always use background images for drop shadows and rounded corners, as you have in the past. 

Closing thoughts

With the advent of CSS3, browsers are just as capable of giving us beautiful, detailed mockups as Photoshop, and in half the time. I’m not the only one to make an argument for this revised process; in his article Time to stop showing clients static design visuals, and in his presentation Walls Come Tumbling Down, Andy Clarke makes a fantastic case for creating your mockups in markup.

So I guess my challenge to you for 2010 is to get out of Photoshop and into the code. Even if the arguments for designing in the browser aren’t enough to make you change your process permanently, it’s worthwhile to give it a try. Look at the New Year as a time to experiment; applying constraints and evaluating old processes can do wonders for improving your efficiency and creativity.",2009,Meagan Fisher,meaganfisher,2009-12-24T00:00:00+00:00,https://24ways.org/2009/make-your-mockup-in-markup/,process
178,Make Out Like a Bandit,"If you are anything like me, you are a professional juggler. No, we don’t juggle bowling pins or anything like that (or do you? Hey, that’s pretty rad!). I’m talking about the work that we juggle daily. In my case, I’m a full-time designer, a half-time graduate student, a sometimes author and conference speaker, and an all-the-time social networker. Only two of these “positions” have actually put any money in my pocket (and, well, the second one takes a lot of money out). Still, this is all part of the work that I do. Your work situation is probably similar. We are workaholics.

So if we work so much in our daily lives, shouldn’t we be making out like bandits? Umm, honestly, I’m not hitting on you, silly. I’m talking about our success. We work and work and work. Shouldn’t we be filthy, stinking rich? Well… okay, that’s not quite what I mean either. I’m not necessarily talking about money (though that could potentially be a part of it). I’m talking about success — as in feeling a true sense of accomplishment and feeling happy about what we do and why we do it.

It’s important to feel accomplished and a general happiness in our work. To make out like a bandit (or have an incredible amount of success), you can either get lucky or work hard for it. And if you’re going to work hard for it, you might as well make it all meaningful and worthwhile. This is what I strive for in my own work and my life, and the following points I’m sharing with you are the steps I am taking to work toward this.


	I know the price of success: dedication, hard work & an unremitting devotion to the things you want to see happen. — Frank Lloyd Wright


Learn. Participate. Do.

The best way to get good at something is to keep doing whatever it is you’re doing that you want to be good at. For example, a sushi-enthusiast might take a sushi-making class because she wants to learn to make sushi for herself. It totally makes sense while the teacher demonstrates all the procedures, materials, and methods needed to make good, beautiful sushi. Later, the student goes home and tries to make sushi on her own, she gets totally confused and lost. Okay, I’m not even going to hide it, I’m talking about myself (this happened to me). As much as I love sushi, I couldn’t even begin to make good sushi because I’ve never really practiced.

Take advantage of learning opportunities where possible. Whether you’re learning CSS, Actionscript, or visual design, the best way to grasp how to do things is to participate, practice, do. Apply what you learn in your work. Participation is so vital to your success. If you have problems, let people know, and ask. But definitely practice on your own. And as cliché as it may sound, believe in yourself because if you don’t think you can do it, no one else will think you can either.

Maintain momentum

With whatever it is you’re doing, if you find yourself “on a roll”, you should take advantage of that momentum and keep moving. Sure, you’ll definitely want to take breaks here or there, but remember that momentum can be very difficult to obtain again once you’ve lost it. Get it done!

Deal with people

Whether you love or hate people, the fact is, you gotta deal with them — even the difficult ones. If you’re in a management position, then you know pretty well that most people don’t like being told what to do (even if that’s their job). Find ways to get people excited about what they’re doing. Make people feel that they (and what they do) are needed — people respond better if they’re valued, not commanded. Even if you’re not in a management position, this still applies to the way you work with your coworkers, clients, vendors, etc.

Resolve any conflicts right away. Conflicts will inevitably happen. Move on to how you can improve the situation, and do it as quickly as possible. Don’t spend too much time focusing on whose screw up it is — nobody feels good in this situation. Also, try to keep people informed on whatever it is you need or what it is you’re doing. If you’re waiting on something from someone, and it’s been a while, don’t be afraid to say something (tactfully). Sometimes people are forgetful — or just slacking. Hey, it happens!

Help yourself by helping others

What are some of the small, simple things you can do when you’re working that will help the people you work with (and in most cases, will end up helping yourself)? For example: if you’re a designer, perhaps taking a couple minutes now to organize and name your Photoshop layers will end up saving time later (since it will be easier to find things). This is going to help both you and your team. Or, developers: taking some time to write some documentation (even if it’s as simple as a comment in the code, or a well-written commit message) could potentially save valuable time for both you and your team later. Maybe you have to take a little time to sit down with a coworker and explain why something works the way it does. This helps them out tremendously — and will most likely lead to them respecting you a little more. This is a benefit.

If you make little things like this a habit, people will notice. People will enjoy working with you. People will trust you and rely on you. Sure, it might seem beneficial at any given moment to be “in it for yourself” (and therefore only helping yourself), but that won’t last very long. Helping others (whether it be a small or large feat) will cause a positive impact in the long run — and that is what will be more valuable to you and your career.

Do work that is meaningful

One of the best ways to feel successful about what you do is to feel good and happy about it. And a great way to feel good and happy about what you’re doing is to actually do good. This could be purpose-driven work that focuses on sustainability and environmentalism, or work that helps support causes and charity. Perhaps the work simply inspires people. Or maybe the work is just something you are very passionate about. Whatever the work may be, try working on projects that are meaningful to you. You’ll do well simply by being more motivated and interested. And it’s a double-win if the project is meaningful to others as well.

I feel very fortunate to work at a place like Crush + Lovely, where we have found quite frequently that the projects that inspire people, focus on global and social good, and create some sort of positive impact are the very projects that bring us more paid projects. But more importantly, we are happy and excited to do it. You might not work at a company that takes on those types of projects. But perhaps you have your own personal endeavors that create this excitement for you. Elliot Jay Stocks wrote about having pet projects. Do you take on side projects? What are those projects?

Over the last couple years, I’ve seen some really fantastic side projects come out that are great examples of meaningful work. These projects reflect the passions and goals of the respective designers and developers involved, and therefore become quite successful (because the people involved simply love what they are doing while they’re doing it). Some of these projects include:


	Typedia is a shared encyclopedia of typefaces which serves as a resource to classify, categorize, and connect typefaces. It was founded by Jason Santa Maria, a graphic designer with a love and passion for typography. He created it as a solution to a problem he faced as a designer: finding the right typeface.
	Huffduffer was created by Jeremy Keith, a web developer who wanted to create a podcast of inspirational talks — but after he found that this could be tedious, he decided to create a tool to automate this.
	Level & Tap was created by passionate photographer and web developer, Tom Watson. It began as a photography print store for Tom’s best personal photography. Over time, more photographers were added to the site and the site has grown to become quite a great collection of beautiful photography.
	Heat Eat Review is a review blog created by information architect and user experience designer, Abi Jones. As a foodie, she is able to use this passion for this blog, as it focuses on reviewing TV Dinners, Frozen Meals, and Microwavable Foods.
	Art in My Coffee, a favorite personal project of my own, is a photo blog of coffee art I created, after I found that my friends and I were frequently posting coffee art photos to Flickr, Twitter, and other websites. After the blog became more popular, I teamed up with Meagan Fisher on the project, who has just as much a passion for coffee art, if not more.


So, what’s important to you?

This is the very, very important question here. What really matters to you most? Beyond just working on meaningful projects you are passionate about, is the work you’re doing the right work for you, so that you can live a good lifestyle? Scott Boms wrote an excellent article, Burnout, in which he shares his own experience in battling stress and exhaustion, and what he learned from it. You should definitely read the article in its entirety, but a couple of his points that are particularly excellent are:


	Make time for numero uno, in which you make time for the things in life that make you happy
	Examine your values, goals, and measures of success, in which you work toward the things you are passionate about, your own personal development, and focusing on the things that matter.


A solid work-life balance can be a challenging struggle to obtain. Of course, you can cheat this by finding ways to combine the things you love with the things you do (so then it doesn’t even feel like you’re working — oh, you sneaky little bandit!). However, there are other factors to consider beyond your general love for the work you’re doing. Take proper care of yourself physically, mentally, and socially.

So, are you making out like a bandit?

Do you feel accomplished and generally happy with your work? If not, perhaps that is something to focus on for the next year. Consider your work (both in your job as well as any side projects you may take on) and how it benefits you — present and future. Take any steps necessary to get you to where you need to be. If you are miserable, fix it!

Finally, it’s important to be thankful for the things that matter to you and make you happy. Pass it along everyday. Thank people. It’s a simple thing, really. Saying “thank you” can and will have enormous impact on the people around you. Oh. And, I apologize if the title of this article led you to thinking it would teach you how to be an amazing kisser. That’s a different article entirely for 24 ways to impress your friends!",2009,Jina Anne,jina,2009-12-21T00:00:00+00:00,https://24ways.org/2009/make-out-like-a-bandit/,business
169,Incite A Riot,"Given its relatively limited scope, HTML can be remarkably expressive. With a bit of lateral thinking, we can mark up content such as tag clouds and progress meters, even when we don’t have explicit HTML elements for those patterns.

Suppose we want to mark up a short conversation:

 
  Alice: I think Eve is watching. 

  Bob: This isn’t a cryptography tutorial …we’re in the wrong example!
 


A note in the the HTML 4.01 spec says it’s okay to use a definition list:


	Another application of DL, for example, is for marking up dialogues, with each DT naming a speaker, and each DD containing his or her words.


That would give us:

<dl>
	<dt>Alice</dt>: <dd>I think Eve is watching.</dd>
	<dt>Bob</dt>: <dd>This isn't a cryptography tutorial ...we're in the wrong example!</dd>
</dl>

This usage of a definition list is proof that writing W3C specifications and smoking crack are not mutually exclusive activities. “I think Eve is watching” is not a definition of “Alice.” If you (ab)use a definition list in this way, Norm will hunt you down.

The conversation problem was revisited in HTML5. What if dt and dd didn’t always mean “definition title” and “definition description”? A new element was forged: dialog. Now the the “d” in dt and dd doesn’t stand for “definition”, it stands for “dialog” (or “dialogue” if you can spell):

<dialog>
	<dt>Alice</dt>: <dd>I think Eve is watching.</dd>
	<dt>Bob</dt>: <dd>This isn't a cryptography tutorial ...we're in the wrong example!</dd>
</dialog>

Problem solved …except that dialog is no longer in the HTML5 spec. Hixie further expanded the meaning of dt and dd so that they could be used inside details (which makes sense—it starts with a “d”) and figure (…um). At the same time as the content model of details and figure were being updated, the completely-unrelated dialog element was dropped.

Back to the drawing board, or in this case, the HTML 4.01 specification. The spec defines the cite element thusly:


	Contains a citation or a reference to other sources.


Perfect! There’s even an example showing how this can applied when attributing quotes to people:

As <CITE>Harry S. Truman</CITE> said,
<Q lang=""en-us"">The buck stops here.</Q>

For longer quotes, the blockquote element might be more appropriate. In a conversation, where the order matters, I think an ordered list would make a good containing element for this pattern:

<ol>
	<li><cite>Alice</cite>: <q>I think Eve is watching.</q></li>
	<li><cite>Bob</cite>: <q>This isn't a cryptography tutorial ...we're in the wrong example!</q></li>
</ol>

Problem solved …except that the cite element has been redefined in the HTML5 spec:


	The cite element represents the title of a work … A person’s name is not the title of a work … and the element must therefore not be used to mark up people’s names.


HTML5 is supposed to be backwards compatible with previous versions of HTML, yet here we have a semantic pattern already defined in HTML 4.01 that is now non-conforming in HTML5. The entire justification for the change boils down to this line of reasoning:


	Given that: titles of works are often italicised and
	given that: people’s names are not often italicised and
	given that: most browsers italicise the contents of the cite element,
	therefore: the cite element should not be used to mark up people’s names.


In other words, the default browser styling is now dictating semantic meaning. The tail is wagging the dog.

Not to worry, the HTML5 spec tells us how we can mark up names in conversations without using the cite element:


	In some cases, the b element might be appropriate for names


I believe the colloquial response to this is a combination of the letters W, T and F, followed by a question mark.

The non-normative note continues:


	In other cases, if an element is really needed, the span element can be used.


This is not a joke. We are seriously being told to use semantically meaningless elements to mark up content that is semantically meaningful.

We don’t have to take it.

Firstly, any conformance checker—that’s the new politically correct term for “validator”—cannot possibly check every instance of the cite element to see if it’s really the title of a work and not the name of a person. So we can disobey the specification without fear of invalidating our documents.

Secondly, Hixie has repeatedly stated that browser makers have a powerful voice in deciding what goes into the HTML5 spec; if a browser maker refuses to implement a feature, then that feature should come out of the spec because otherwise, the spec is fiction. Well, one of the design principles of HTML5 is the Priority of Constituencies:


	In case of conflict, consider users over authors over implementors over specifiers over theoretical purity.


That places us—authors—above browser makers. If we resolutely refuse to implement part of the HTML5 spec, then the spec becomes fiction.

Join me in a campaign of civil disobedience against the unnecessarily restrictive, backwards-incompatible change to the cite element. Start using HTML5 but start using it sensibly. Let’s ensure that bad advice remains fictitious.

Tantek has set up a page on the WHATWG wiki to document usage of the cite element for conversations. Please contribute to it.",2009,Jeremy Keith,jeremykeith,2009-12-11T00:00:00+00:00,https://24ways.org/2009/incite-a-riot/,code
189,Ignorance Is Bliss,"This is a true story.

Meet Mike 

Mike’s a smart guy. He knows a great browser when he sees one. He uses Firefox on his Windows PC at work and Safari on his Mac at home. Mike asked us to design a Web site for his business. So we did.

We wanted to make the best Web site for Mike that we could, so we used all of the CSS tools that are available today. That meant using RGBa colour to layer elements, border-radius to add subtle rounded corners and (possibly most experimental of all new CSS), generated gradients.

 The home page Mike sees in Safari on his Mac

Mike loves what he sees.

Meet Sam

Sam works with Mike. She uses Internet Explorer 7 because it came on the Windows laptop that the company bought her when she joined. 

 The home page Sam sees in Internet Explorer 7 on her PC

Sam loves the new Web site too.

How could both of them be happy when they experienced the Web site differently?

The new WYSIWYG

When I first presented my designs to Mike and Sam, I showed them a Web page made with HTML and CSS in their respective browsers and not a picture of a Web page. By showing neither a static image of my design, I set none of the false expectations that, by definition, a static Photoshop or Fireworks visual would have established.

Mike saw rounded corners and subtle shadows in Firefox and Safari. Sam saw something equally as nice, just a little different, in Internet Explorer. Both were very happy because they saw something that they liked.

Neither knew, or needed to know, about the subtle differences between browsers. Their users don’t need to know either.

That’s because in the real world, people using the Web don’t find a Web site that they like, then open up another browser to check that it looks they same. They simply buy what they came to buy, read what what they came to read, do what they came to do, then get on with their lives in blissful ignorance of what they might be seeing in another browser.

Often when I talk or write about using progressive CSS, people ask me, “How do you convince clients to let you work that way? What’s your secret?” Secret? I tell them what they need to know, on a need-to-know basis.

Epilogue

Sam has a new iPhone that Mike bought for her as a reward for achieving her sales targets. She loves her iPhone and was surprised at just how fast and good-looking the company Web site appears on that. So she asked,


	“Andy, I didn’t know you optimised our site for mobile. I don’t remember seeing an invoice for that.”


I smiled.

177,"HTML5: Tool of Satan, or Yule of Santa?","It would lead to unseasonal arguments to discuss the title of this piece here, and the arguments are as indigestible as the fourth turkey curry of the season, so we’ll restrict our article to the practical rather than the philosophical: what HTML5 can you reasonably expect to be able to use reliably cross-browser in the early months of 2010?

The answer is that you can use more than you might think, due to the seasonal tinsel of feature-detection and using the sparkly pixie-dust of IE-only VML (but used in a way that won’t damage your Elf).

Canvas

canvas is a 2D drawing API that defines a blank area of the screen of arbitrary size, and allows you to draw on it using JavaScript. The pictures can be animated, such as in this canvas mashup of Wolfenstein 3D and Flickr. (The difference between canvas and SVG is that SVG uses vector graphics, so is infinitely scalable. It also keeps a DOM, whereas canvas is just pixels so you have to do all your own book-keeping yourself in JavaScript if you want to know where aliens are on screen, or do collision detection.)

Previously, you needed to do this using Adobe Flash or Java applets, requiring plugins and potentially compromising keyboard accessibility. Canvas drawing is supported now in Opera, Safari, Chrome and Firefox. The reindeer in the corner is, of course, Internet Explorer, which currently has zero support for canvas (or SVG, come to that).

Now, don’t pull a face like all you’ve found in your Yuletide stocking is a mouldy satsuma and a couple of nuts—that’s not the end of the story. Canvas was originally an Apple proprietary technology, and Internet Explorer had a similar one called Vector Markup Language which was submitted to the W3C for standardisation in 1998 but which, unlike canvas, was not blessed with retrospective standardisation.

What you need, then, is some way for Internet Explorer to translate canvas to VML on-the-fly, while leaving the other, more standards-compliant browsers to use the HTML5. And such a way exists—it’s a JavaScript library called excanvas. It’s downloadable from http://code.google.com/p/explorercanvas/ and it’s simple to include it via a conditional comment in the head for IE:

<!--[if IE]>
<script src=""excanvas.js""></script>
<![endif]-->

Simply include this, and your canvas will be natively supported in the modern browsers (and the library won’t even be downloaded) whereas IE will suddenly render your canvas using its own VML engine. Be sure, however, to check it carefully, as the IE JavaScript engine isn’t so fast and you’ll need to be sure that performance isn’t too degraded to use.

Forms

Since the beginning of the Web, developers have been coding forms, and then writing JavaScript to check whether an input is a correctly formed email address, URL, credit card number or conforms to some other pattern. The cumulative labour of the world’s developers over the last 15 years makes whizzing round in a sleigh and delivering presents seem like popping to the corner shop in comparison.

With HTML5, that’s all about to change. As Yaili began to explore on Day 3, a host of new attributes to the input element provide built-in validation for email address formats (input type=email), URLs (input type=url), any pattern that can be expressed with a JavaScript-syntax regex (pattern=""[0-9][A-Z]{3}"") and the like. New attributes such as required, autofocus, input type=number min=3 max=50 remove much of the tedious JavaScript from form validation.

Other, really exciting input types are available (see all input types). The datalist is reminiscent of a select box, but allows the user to enter their own text if they don’t want to choose one of the pre-defined options. input type=range is rendered as a slider, while input type=date pops up a date picker, all natively in the browser with no JavaScript required at all.

Currently, support is most complete in an experimental implementation in Opera and a number of the new attributes in Webkit-based browsers. But don’t let that stop you! The clever thing about the specification of the new Web Forms is that all the new input types are attributes (rather than elements). input defaults to input type=text, so if a browser doesn’t understand a new HTML5 type, it gracefully degrades to a plain text input.

So where does that leave validation in those browsers that don’t support Web Forms? The answer is that you don’t retire your pre-existing JavaScript validation just yet, but you leave it as a fallback after doing some feature detection. To detect whether (say) input type=email is supported, you make a new input type=email with JavaScript but don’t add it to the page. Then, you interrogate your new element to find out what its type attribute is. If it’s reported back as “email”, then the browser supports the new feature, so let it do its work and don’t bring in any JavaScript validation. If it’s reported back as “text”, it’s fallen back to the default, indicating that it’s not supported, so your code should branch to your old validation routines. Alternatively, use the small (7K) Modernizr library which will do this work for you and give you JavaScript booleans like Modernizr.inputtypes[email] set to true or false.

So what does this buy you? Well, first and foremost, you’re future-proofing your code for that time when all browsers support these hugely useful additions to forms. Secondly, you buy a usability and accessibility win. Although it’s tempting to style the stuffing out of your form fields (which can, incidentally, lead to madness), whatever your branding people say, it’s better to leave forms as close to the browser defaults as possible. A browser’s slider and date pickers will be the same across different sites, making it much more comprehensible to users. And, by using native controls rather than faking sliders and date pickers with JavaScript, your forms are much more likely to be accessible to users of assistive technology.

HTML5 DOCTYPE

You can use the new DOCTYPE !doctype html now and – hey presto – you’re writing HTML5, as it’s pretty much a superset of HTML4. There are some useful advantages to doing this. The first is that the HTML5 validator (I use http://html5.validator.nu) also validates ARIA information, whereas the HTML4 validator doesn’t, as ARIA is a new spec developed after HTML4. (Actually, it’s more accurate to say that it doesn’t validate your ARIA attributes, but it doesn’t automatically report them as an error.)

Another advantage is that HTML5 allows tabindex as a global attribute (that is, on any element). Although originally designed as an accessibility bolt-on, I ordinarily advise you don’t use it; a well-structured page should provide a logical tab order through links and form fields already.

However, tabindex=""-1"" is a legal value in HTML5 as it allows for the element to be programmatically focussable by JavaScript. It’s also very useful for correcting a bug in Internet Explorer when used with a keyboard; in-page links go nowhere if the destination doesn’t have a proprietary property called hasLayout set or a tabindex of -1.

So, whether it is the tool of Satan or yule of Santa, HTML5 is just around the corner. Some you can use now, and by the end of 2010 I predict you’ll be able to use a whole lot more as new browser versions are released.",2009,Bruce Lawson,brucelawson,2009-12-05T00:00:00+00:00,https://24ways.org/2009/html5-tool-of-satan-or-yule-of-santa/,code
179,Have a Field Day with HTML5 Forms,"Forms are usually seen as that obnoxious thing we have to markup and style. I respectfully disagree: forms (on a par with tables) are the most exciting thing we have to work with.

Here we’re going to take a look at how to style a beautiful HTML5 form using some advanced CSS and latest CSS3 techniques. I promise you will want to style your own forms after you’ve read this article.

Here’s what we’ll be creating:

 The form. (Icons from Chalkwork Payments)

Meaningful markup

We’re going to style a simple payment form. There are three main sections on this form:


	The person’s details
	The address details
	The credit card details


We are also going to use some of HTML5’s new input types and attributes to create more meaningful fields and use less unnecessary classes and ids:


	email, for the email field
	tel, for the telephone field
	number, for the credit card number and security code
	required, for required fields
	placeholder, for the hints within some of the fields
	autofocus, to put focus on the first input field when the page loads


There are a million more new input types and form attributes on HTML5, and you should definitely take a look at what’s new on the W3C website. Hopefully this will give you a good idea of how much more fun form markup can be.

A good foundation

Each section of the form will be contained within its own fieldset. In the case of the radio buttons for choosing the card type, we will enclose those options in another nested fieldset.

We will also be using an ordered list to group each label / input pair. This will provide us with a (kind of) semantic styling hook and it will also make the form easier to read when viewing with no CSS applied:

 The unstyled form

So here’s the markup we are going to be working with:

<form id=payment>
	<fieldset>
		<legend>Your details</legend>
		<ol>
			<li>
				<label for=name>Name</label>
				<input id=name name=name type=text placeholder=""First and last name"" required autofocus>
			</li>
			<li>
				<label for=email>Email</label>
				<input id=email name=email type=email placeholder=""example@domain.com"" required>
			</li>
			<li>
				<label for=phone>Phone</label>
				<input id=phone name=phone type=tel placeholder=""Eg. +447500000000"" required>
			</li>
		</ol>
	</fieldset>
	<fieldset>
		<legend>Delivery address</legend>
		<ol>
			<li>
				<label for=address>Address</label>
				<textarea id=address name=address rows=5 required></textarea>
			</li>
			<li>
				<label for=postcode>Post code</label>
				<input id=postcode name=postcode type=text required>
			</li>
			<li>
				<label for=country>Country</label>
				<input id=country name=country type=text required>
			</li>
		</ol>
	</fieldset>
	<fieldset>
		<legend>Card details</legend>
		<ol>		
			<li>
				<fieldset>
					<legend>Card type</legend>
					<ol>
						<li>
							<input id=visa name=cardtype type=radio>
							<label for=visa>VISA</label>
						</li>
						<li>
							<input id=amex name=cardtype type=radio>
							<label for=amex>AmEx</label>
						</li>
						<li>
							<input id=mastercard name=cardtype type=radio>
							<label for=mastercard>Mastercard</label>
						</li>
					</ol>
				</fieldset>
			</li>
			<li>
				<label for=cardnumber>Card number</label>
				<input id=cardnumber name=cardnumber type=number required>
			</li>
			<li>
				<label for=secure>Security code</label>
				<input id=secure name=secure type=number required>
			</li>
			<li>
				<label for=namecard>Name on card</label>
				<input id=namecard name=namecard type=text placeholder=""Exact name as on the card"" required>
			</li>
		</ol>
	</fieldset>
	<fieldset>
		<button type=submit>Buy it!</button>
	</fieldset>
</form>

Making things look nice

First things first, so let’s start by adding some defaults to our form by resetting the margins and paddings of the elements and adding a default font to the page:

html, body, h1, form, fieldset, legend, ol, li {
	margin: 0;
	padding: 0;
}
body {
	background: #ffffff;
	color: #111111;
	font-family: Georgia, ""Times New Roman"", Times, serif;
	padding: 20px;
}

Next we are going to style the form element that is wrapping our fields:

form#payment {
	background: #9cbc2c;
	-moz-border-radius: 5px;
	-webkit-border-radius: 5px;
	border-radius: 5px;
	padding: 20px;
	width: 400px;
}

We will also remove the border from the fieldset and apply some bottom margin to it. Using the :last-of-type pseudo-class, we remove the bottom margin of the last fieldset — there is no need for it:

form#payment fieldset {
	border: none;
	margin-bottom: 10px;
}
form#payment fieldset:last-of-type {
	margin-bottom: 0;
}

Next we’ll make the legends big and bold, and we will also apply a light-green text-shadow, to add that little extra special detail:

form#payment legend {
	color: #384313;
	font-size: 16px;
	font-weight: bold;
	padding-bottom: 10px;
	text-shadow: 0 1px 1px #c0d576;
}

Our legends are looking great, but how about adding a clear indication of how many steps our form has? Instead of adding that manually to every legend, we can use automatically generated counters.

To add a counter to an element, we have to use either the :before or :after pseudo-elements to add content via CSS. We will follow these steps:


	create a counter using the counter-reset property on the form element
	call the counter with the content property (using the same name we’ve created before)
	with the counter-incremet property, indicate that for each element that matches our selector, that counter will be increased by 1


form#payment > fieldset > legend:before {
	content: ""Step "" counter(fieldsets) "": "";
	counter-increment: fieldsets;
}

Finally, we need to change the style of the legend that is part of the radio buttons group, to make it look like a label:

form#payment fieldset fieldset legend {
	color: #111111;
	font-size: 13px;
	font-weight: normal;
	padding-bottom: 0;
}

Styling the lists

For our list elements, we’ll just add some nice rounded corners and semi-transparent border and background. Because we are using RGBa colors, we should provide a fallback for browsers that don’t support them (that comes before the RBGa color). For the nested lists, we will remove these properties because they would be overlapping:

form#payment ol li {
	background: #b9cf6a;
	background: rgba(255,255,255,.3);
	border-color: #e3ebc3;
	border-color: rgba(255,255,255,.6);
	border-style: solid;
	border-width: 2px;
	-moz-border-radius: 5px;
	-webkit-border-radius: 5px;
	border-radius: 5px;
	line-height: 30px;
	list-style: none;
	padding: 5px 10px;
	margin-bottom: 2px;
}
form#payment ol ol li {
	background: none;
	border: none;
	float: left;
}

Form controls

Now we only need to style our labels, inputs and the button element.

All our labels will look the same, with the exception of the one for the radio elements. We will float them to the left and give them a width.

For the credit card type labels, we will add an icon as the background, and override some of the properties that aren’t necessary. We will be using the attribute selector to specify the background image for each label — in this case, we use the for attribute of each label.

To add an extra user-friendly detail, we’ll add a cursor: pointer to the radio button labels on the :hover state, so the user knows that he can simply click them to select that option.

form#payment label {
	float: left;
	font-size: 13px;
	width: 110px;
}
form#payment fieldset fieldset label {
	background:none no-repeat left 50%;
	line-height: 20px;
	padding: 0 0 0 30px;
	width: auto;
}
form#payment label[for=visa] {
	background-image: url(visa.gif);
}
form#payment label[for=amex] {
	background-image: url(amex.gif);
}
form#payment label[for=mastercard] {
	background-image: url(mastercard.gif);
}
form#payment fieldset fieldset label:hover {
	cursor: pointer;
}

Almost there! Now onto the input elements. Here we want to match all inputs, except for the radio ones, and the textarea. For that we will use the negation pseudo-class (:not()). With it we can target all input elements except for the ones with type of radio.

We will also make sure to add some :focus styles and add the appropriate styling for the radio inputs:

form#payment input:not([type=radio]),
form#payment textarea {
	background: #ffffff;
	border: none;
	-moz-border-radius: 3px;
	-webkit-border-radius: 3px;
	-khtml-border-radius: 3px;
	border-radius: 3px;
	font: italic 13px Georgia, ""Times New Roman"", Times, serif;
	outline: none;
	padding: 5px;
	width: 200px;
}
form#payment input:not([type=submit]):focus,
form#payment textarea:focus {
	background: #eaeaea;
}
form#payment input[type=radio] {
	float: left;
	margin-right: 5px;
}

And finally we come to our submit button. To it, we will just add some nice typography and text-shadow, align it to the center of the form and give it some background colors for its different states:

form#payment button {

180,Going Nuts with CSS Transitions,"I’m going to show you how CSS 3 transforms and WebKit transitions can add zing to the way you present images on your site.

Laying the foundations

First we are going to make our images look like mini polaroids with captions. Here’s the markup:

<div class=""polaroid pull-right"">
	<img src=""../img/seal.jpg"" alt="""">
	<p class=""caption"">Found this little cutie on a walk in New Zealand!</p>
</div>

You’ll notice we’re using a somewhat presentational class of pull-right here. This means the logic is kept separate from the code that applies the polaroid effect. The polaroid class has no positioning, which allows it to be used generically anywhere that the effect is required. The pull classes set a float and add appropriate margins—they can be used for things like blockquotes as well.

.polaroid {
	width: 150px;
	padding: 10px 10px 20px 10px;
	border: 1px solid #BFBFBF;
	background-color: white;
	-webkit-box-shadow: 2px 2px 3px rgba(135, 139, 144, 0.4);
	-moz-box-shadow: 2px 2px 3px rgba(135, 139, 144, 0.4);
	box-shadow: 2px 2px 3px rgba(135, 139, 144, 0.4);
}

The actual polaroid effect itself is simply applied using padding, a border and a background colour. We also apply a nice subtle box shadow, using a property that is supported by modern WebKit browsers and Firefox 3.5+. We include the box-shadow property last to ensure that future browsers that support the eventual CSS3 specified version natively will use that implementation over the legacy browser specific version.

The box-shadow property takes four values: three lengths and a colour. The first is the horizontal offset of the shadow—positive values place the shadow on the right, while negative values place it to the left. The second is the vertical offset, positive meaning below. If both of these are set to 0, the shadow is positioned equally on all four sides. The last length value sets the blur radius—the larger the number, the blurrier the shadow (therefore the darker you need to make the colour to have an effect).

The colour value can be given in any format recognised by CSS. Here, we’re using rgba as explained by Drew behind the first door of this year’s calendar.

Rotation

For browsers that understand it (currently our old favourites WebKit and FF3.5+) we can add some visual flair by rotating the image, using the transform CSS 3 property.

-webkit-transform: rotate(9deg);
-moz-transform: rotate(9deg);
transform: rotate(9deg);

Rotations can be specified in degrees, radians (rads) or grads. WebKit also supports turns unfortunately Firefox doesn’t just yet.

For our example, we want any polaroid images on the left hand side to be rotated in the opposite direction, using a negative degree value:

.pull-left.polaroid {
	-webkit-transform: rotate(-9deg);
	-moz-transform: rotate(-9deg);
	transform: rotate(-9deg);
}

Multiple class selectors don’t work in IE6 but as luck would have it, the transform property doesn’t work in any current IE version either. The above code is a good example of progressive enrichment: browsers that don’t support box-shadow or transform will still see the image and basic polaroid effect.



Animation

WebKit is unique amongst browser rendering engines in that it allows animation to be specified in pure CSS. Although this may never actually make it in to the CSS 3 specification, it degrades nicely and more importantly is an awful lot of fun!

Let’s go nuts.

In the next demo, the image is contained within a link and mousing over that link causes the polaroid to animate from being angled to being straight.

Here’s our new markup:

<a href=""http://www.flickr.com/photos/nataliedowne/2340993237/"" class=""polaroid"">
	<img src=""../img/raft.jpg"" alt="""">
	White water rafting in Queenstown
</a>

And here are the relevant lines of CSS:

a.polaroid {
	/* ... */
   -webkit-transform: rotate(10deg);
   -webkit-transition: -webkit-transform 0.5s ease-in;
}
a.polaroid:hover,
a.polaroid:focus,
a.polaroid:active {
	/* ... */
	-webkit-transform: rotate(0deg);
}

The @-webkit-transition@ property is the magic wand that sets up the animation. It takes three values: the property to be animated, the duration of the animation and a ‘timing function’ (which affects the animation’s acceleration, for a smoother effect).

-webkit-transition only takes affect when the specified property changes. In pure CSS, this is done using dynamic pseudo-classes. You can also change the properties using JavaScript, but that’s a story for another time.

Throwing polaroids at a table

Imagine there are lots of differently sized polaroid photos scattered on a table. That’s the effect we are aiming for with our next demo.



As an aside: we are using absolute positioning to arrange the images inside a flexible width container (with a minimum and maximum width specified in pixels). As some are positioned from the left and some from the right when you resize the browser they shuffle underneath each other. This is an effect used on the UX London site.

This demo uses a darker colour shadow with more transparency than before. The grey shadow in the previous example worked fine, but it was against a solid background. Since the images are now overlapping each other, the more opaque shadow looked fake.

-webkit-box-shadow: 2px 2px 4px rgba(0,0, 0, 0.3);
-moz-box-shadow: 2px 2px 4px rgba(0,0, 0, 0.3);
box-shadow: 2px 2px 4px rgba(0,0, 0, 0.3);

On hover, as well as our previous trick of animating the image rotation back to straight, we are also making the shadow darker and setting the z-index to be higher than the other images so that it appears on top.

And Finally…

Finally, for a bit more fun, we’re going to simulate the images coming towards you and lifting off the page. We’ll achieve this by making them grow larger and by offsetting the shadow & making it longer.




Screenshot 1 shows the default state, while 2 shows our previous hover effect. Screenshot 3 is the effect we are aiming for, illustrated by demo 4.

a.polaroid {
	/* ... */
	z-index: 2;
	-webkit-box-shadow: 2px 2px 4px rgba(0,0, 0, 0.3);
	-moz-box-shadow: 2px 2px 4px rgba(0,0, 0, 0.3);
	box-shadow: 2px 2px 4px rgba(0,0, 0, 0.3);
	-webkit-transform: rotate(10deg);
	-moz-transform: rotate(10deg);
	transform: rotate(10deg);
	-webkit-transition: all 0.5s ease-in;
}
a.polaroid:hover,
a.polaroid:focus,
a.polaroid:active {
	z-index: 999;
	border-color: #6A6A6A;
	-webkit-box-shadow: 15px 15px 20px rgba(0,0, 0, 0.4);
	-moz-box-shadow: 15px 15px 20px rgba(0,0, 0, 0.4);
	box-shadow: 15px 15px 20px rgba(0,0, 0, 0.4);
	-webkit-transform: rotate(0deg) scale(1.05);
	-moz-transform: rotate(0deg) scale(1.05);
	transform: rotate(0deg) scale(1.05);
}

You’ll notice we are now giving the transform property another transform function: scale, which takes increases the size by the specified factor. Other things you can do with transform include skewing, translating or you can go mad creating your own transforms with a matrix.

The box-shadow has both its offset and blur radius increased dramatically, and is darkened using the alpha channel of the rgba colour.

And because we want the effects to all animate smoothly, we pass a value of all to the -webkit-transition property, ensuring that any changed property on that link will be animated.

Demo 5 is the finished example, bringing everything nicely together.

CSS transitions and transforms are a great example of progressive enrichment, which means improving the experience for a portion of the audience without negatively affecting other users. They are also a lot of fun to play with!

175,Front-End Code Reusability with CSS and JavaScript,"Most web standards-based developers are more than familiar with creating their sites with semantic HTML with lots and lots of CSS. With each new page in a design, the CSS tends to grow and grow and more elements and styles are added. But CSS can be used to better effect.

The idea of object-oriented CSS isn’t new. Nicole Sullivan has written a presentation on the subject and outlines two main concepts: separate structure and visual design; and separate container and content. Jeff Croft talks about Applying OOP Concepts to CSS:


	I can make a class of .box that defines some basic layout structure, and another class of .rounded that provides rounded corners, and classes of .wide and .narrow that define some widths, and then easily create boxes of varying widths and styles by assigning multiple classes to an element, without having to duplicate code in my CSS.


This concept helps reduce CSS file size, allows for great flexibility, rapid building of similar content areas and means greater consistency throughout the entire design. You can also take this concept one step further and apply it to site behaviour with JavaScript.

Build a versatile slideshow

I will show you how to build multiple slideshows using jQuery, allowing varying levels of functionality which you may find on one site design. The code will be flexible enough to allow you to add previous/next links, image pagination and the ability to change the animation type. More importantly, it will allow you to apply any combination of these features.

Image galleries are simply a list of images, so the obvious choice of marking the content up is to use a <ul>. Many designs, however, do not cater to non-JavaScript versions of the website, and thus don’t take in to account large multiple images. You could also simply hide all the other images in the list, apart from the first image. This method can waste bandwidth because the other images might be downloaded when they are never going to be seen.

Taking this second concept — only showing one image — the only code you need to start your slideshow is an <img> tag. The other images can be loaded dynamically via either a per-page JavaScript array or via AJAX.

The slideshow concept is built upon the very versatile Cycle jQuery Plugin and is structured in to another reusable jQuery plugin. Below is the HTML and JavaScript snippet needed to run every different type of slideshow I have mentioned above.

<img src=""path/to/image.jpg"" alt=""About the image"" title="""" height=""250"" width=""400"" class=""slideshow"">
<script type=""text/javascript"">
	jQuery().ready(function($) {
		$('img.slideshow').slideShow({
			images: ['1.jpg', '2.jpg', '3.jpg']
		});
	});
</script>

Slideshow plugin

If you’re not familiar with jQuery or how to write and author your own plugin there are plenty of articles to help you out.

jQuery has a chainable interface and this is something your plugin must implement. This is easy to achieve, so your plugin simply returns the collection it is using:

return this.each(
	function () {}
};

Local Variables

To keep the JavaScript clean and avoid any conflicts, you must set up any variables which are local to the plugin and should be used on each collection item. Defining all your variables at the top under one statement makes adding more and finding which variables are used easier. For other tips, conventions and improvements check out JSLint, the “JavaScript Code Quality Tool”.

var $$, $div, $images, $arrows, $pager,
	id, selector, path, o, options,
	height, width,
	list = [], li = 0,
	parts = [], pi = 0,
	arrows = ['Previous', 'Next'];

Cache jQuery Objects

It is good practice to cache any calls made to jQuery. This reduces wasted DOM calls, can improve the speed of your JavaScript code and makes code more reusable.

The following code snippet caches the current selected DOM element as a jQuery object using the variable name $$. Secondly, the plugin makes its settings available to the Metadata plugin‡ which is best practice within jQuery plugins.

For each slideshow the plugin generates a <div> with a class of slideshow and a unique id. This is used to wrap the slideshow images, pagination and controls.

The base path which is used for all the images in the slideshow is calculated based on the existing image which appears on the page. For example, if the path to the image on the page was /img/flowers/1.jpg the plugin would use the path /img/flowers/ to load the other images.

$$ = $(this);
o = $.metadata ? $.extend({}, settings, $$.metadata()) : settings;
id = 'slideshow-' + (i++ + 1);
$div = $('<div />').addClass('slideshow').attr('id', id);
selector = '#' + id + ' ';
path = $$.attr('src').replace(/[0-9]\.jpg/g, '');
options = {};
height = $$.height();
width = $$.width();

Note: the plugin uses conventions such as folder structure and numeric filenames. These conventions help with the reusable aspect of plugins and best practices.

Build the Images

The cycle plugin uses a list of images to create the slideshow. Because we chose to start with one image we must now build the list programmatically. This is a case of looping through the images which were added via the plugin options, building the appropriate HTML and appending the resulting <ul> to the DOM.

$.each(o.images, function () {
	list[li++] = '<li>';
	list[li++] = '<img src=""' + path + this + '"" height=""' + height + '"" width=""' + width + '"">';
	list[li++] = '</li>';
});
$images = $('<ul />').addClass('cycle-images');
$images.append(list.join('')).appendTo($div);

Although jQuery provides the append method it is much faster to create one really long string and append it to the DOM at the end.

Update the Options

Here are some of the options we’re making available by simply adding classes to the <img>. You can change the slideshow effect from the default fade to the sliding effect. By adding the class of stopped the slideshow will not auto-play and must be controlled via pagination or previous and next links.

// different effect
if ($$.is('.slide')) {
	options.fx = 'scrollHorz';
}
// don't move by default
if ($$.is('.stopped')) {
	options.timeout = 0;
}

If you are using the same set of images throughout a website you may wish to start on a different image on each page or section. This can be easily achieved by simply adding the appropriate starting class to the <img>.

// based on the class name on the image
if ($$.is('[class*=start-]')) {
	options.startingSlide = parseInt($$.attr('class').replace(/.*start-([0-9]+).*/g, ""$1""), 10) - 1;
}

For example:

<img src=""/img/slideshow/3.jpg"" alt=""About the image"" title="""" height=""250"" width=""400"" class=""slideshow start-3"">

By default, and without JavaScript, the third image in this slideshow is shown. When the JavaScript is applied to the page the slideshow must know to start from the correct place, this is why the start class is required.

You could capture the default image name and parse it to get the position, but only the default image needs to be numeric to work with this plugin (and could easily be changed in future). Therefore, this extra specifically defined option means the plugin is more tolerant.

Previous/Next Links

A common feature of slideshows is previous and next links enabling the user to manually progress the images. The Cycle plugin supports this functionality, but you must generate the markup yourself. Most people add these directly in the HTML but normally only support their behaviour when JavaScript is enabled. This goes against progressive enhancement. To keep with the best practice progress enhancement method the previous/next links should be generated with JavaScript.

The follow snippet checks whether the slideshow requires the previous/next links, via the arrows class. It restricts the Cycle plugin to the specific slideshow using the selector we created at the top of the plugin. This means multiple slideshows can run on one page without conflicting each other.

The code creates a <ul> using the arrows array we defined at the top of the plugin. It also adds a class to the slideshow container, meaning you can style different combinations of options in your CSS.

// create the arrows
if ($$.is('.arrows') && list.length > 1) {
	options.next = selector + '.next';
	options.prev = selector + '.previous';
	$arrows = $('<ul />').addClass('cycle-arrows');
	$.each(arrows, function (i, val) {
		parts[pi++] = '<li class=""' + val.toLowerCase() + '"">';
		parts[pi++] = '<a href=""#' + val.toLowerCase() + '"">';
		parts[pi++] = '<span>' + val + '</span>';
		parts[pi++] = '</a>';
		parts[pi++] = '</li>';
	});
	$arrows.append(parts.join('')).appendTo($div);
	$div.addClass('has-cycle-arrows');
}

The arrow array could be placed inside the plugin settings to allow for localisation.

Pagination

The Cycle plugin creates its own HTML for the pagination of the slideshow. All our plugin needs to do is create the list and selector to use. This snippet creates the pagination container and appends it to our specific slideshow container. It sets the Cycle plugin pager option, restricting it to the specific slideshow using the selector we created at the top of the plugin. Like the previous/next links, a class is added to the slideshow container allowing you to style the slideshow itself differently.

// create the clickable pagination
if ($$.is('.pagination') && list.length > 1) {
	options.pager = selector + '.cycle-pagination';
	$pager = $('<ul />').addClass('cycle-pagination');
	$pager.appendTo($div);
	$div.addClass('has-cycle-pagination');
}

Note: the Cycle plugin creates a <ul> with anchors listed directly inside without the surrounding <li>. Unfortunately this is invalid markup but the code still works.

Demos

Well, that describes all the ins-and-outs of the plugin, but demos make it easier to understand! Viewing the source on the demo page shows some of the combinations you can create with a simple <img>, a few classes and some thought-out JavaScript.

View the demos →

Decide on defaults

The slideshow plugin uses the exact same settings as the Cycle plugin, but some are explicitly set within the slideshow plugin when using the classes you have set.

When deciding on what functionality is going to be controlled via this class method, be careful to choose your defaults wisely. If all slideshows should auto-play, don’t make this an option — make the option to stop the auto-play. Similarly, if every slideshow should have previous/next functionality make this the default and expose the ability to remove them with a class such as “no-pagination”.

In the examples presented on this article I have used a class on each <img>. You can easily change this to anything you want and simply apply the plugin based on the jQuery selector required.

Grab your images

If you are using AJAX to load in your images, you can speed up development by deciding on and keeping to a folder structure and naming convention. There are two methods: basing the image path based on the current URL; or based on the src of the image. The first allows a different slideshow on each page, but in many instances a site will have a couple of sets of images and therefore the second method is probably preferred.

Metadata ‡

A method which allows you to directly modify settings in certain plugins, which also uses the classes from your HTML already exists. This is a jQuery plugin called Metadata. This method allows for finer control over the plugin settings themselves. Some people, however, may dislike the syntax and prefer using normal classes, like above which when sprinkled with a bit more JavaScript allows you to control what you need to control.

The takeaway

Hopefully you have understood not only what goes in to a basic jQuery plugin but also learnt a new and powerful idea which you can apply to other areas of your website.

The idea can also be applied to other common interfaces such as lightboxes or mapping services such as Google Maps — for example creating markers based on a list of places, each with different pin icons based the anchor class.",2009,Trevor Morris,trevormorris,2009-12-06T00:00:00+00:00,https://24ways.org/2009/front-end-code-reusability-with-css-and-javascript/,code
188,Don't Lose Your :focus,"For many web designers, accessibility conjures up images of blind users with screenreaders, and the difficulties in making sites accessible to this particular audience. Of course, accessibility covers a wide range of situations that go beyond the extreme example of screenreader users. And while it’s true that making a complex site accessible can often be a daunting prospect, there are also many small things that don’t take anything more than a bit of judicious planning, are very easy to test (without having to buy expensive assistive technology), and can make all the difference to certain user groups.

In this short article we’ll focus on keyboard accessibility and how careless use of CSS can potentially make your sites completely unusable.

Keyboard Access

Users who for whatever reason can’t use a mouse will employ a keyboard (or keyboard-like custom interface) to navigate around web pages. By default, they will use TAB and SHIFT + TAB to move from one focusable element (links, form controls and area) of a page to the next.

Note: in OS X, you’ll first need to turn on full keyboard access under System Preferences > Keyboard and Mouse > Keyboard Shortcuts. Safari under Windows needs to have the option Press Tab to highlight each item on a webpage in Preferences > Advanced enabled. Opera is the odd one out, as it has a variety of keyboard navigation options – the most relevant here being spatial navigation via Shift+Down, Shift+Up, Shift+Left, and Shift+Right).

But I Don’t Like Your Dotted Lines…

To show users where they are within a page, browsers place an outline around the element that currently has focus. The “problem” with these default outlines is that some browsers (Internet Explorer and Firefox) also display them when a user clicks on a focusable element with the mouse. Particularly on sites that make extensive use of image replacement on links with “off left” techniques this can create very unsightly outlines that stretch from the replaced element all the way to the left edge of the browser.

 Outline bleeding off to the left (image-replacement example from carsonified.com)

There is a trivial workaround to prevent outlines from “spilling over” by adding a simple overflow:hidden, which keeps the outline in check around the clickable portion of the image-replaced element itself.

 Outline tamed with overflow:hidden

But for many designers, even this is not enough. As a final solution, many actively suppress outlines altogether in their stylesheets. Controversially, even Eric Meyer’s popular reset.css – an otherwise excellent set of styles that levels the playing field of varying browser defaults – suppresses outlines.

html, body, div, span, applet, object, iframe ... {
	...
	outline: 0;
	...
}
/* remember to define focus styles! */
:focus {
	outline: 0;
}

Yes, in his explanation (and in the CSS itself) Eric does remind designers to define relevant styles for :focus… but judging by the number of sites that seem to ignore this (and often remove the related comment from the stylesheet altogether), the message doesn’t seem to have sunk in.

Anyway… hurrah! No more unsightly dotted lines on our lovely design. But what about keyboard users? Although technically they can still TAB from one element to the next, they now get no default cue as to where they are within the page (one notable exception here is Opera, where the outline is displayed regardless of stylesheets)… and if they’re Safari users, they won’t even get an indication of a link’s target in the status bar, like they would if they hovered over it with the mouse.

Only Suppress outline For Mouse Users

Is there a way to allow users navigating with the keyboard to retain the standard outline behaviour they’ve come to expect from their browser, while also ensuring that it doesn’t show display for mouse users?

 Testing some convoluted style combinations

After playing with various approaches (see Better CSS outline suppression for more details), the most elegant solution also seemed to be the simplest: don’t remove the outline on :focus, do it on :active instead – after all, :active is the dynamic pseudo-class that deals explicitly with the styles that should be applied when a focusable element is clicked or otherwise activated.

a:active { outline: none; }

The only minor issues with this method: if a user activates a link and then uses the browser’s back button, the outline becomes visible. Oh, and old versions of Internet Explorer notoriously get confused by the exact meaning of :focus, :hover and :active, so this method fails in IE6 and below. Personally, I can live with both of these.

Note: at the last minute before submitting this article, I discovered a fatal flaw in my test. It appears that outline still manages to appear in the time between activating a link and the link target loading (which in hindsight is logical – after activation, the link does indeed receive focus). As my test page only used in-page links, this issue never came up before. The slightly less elegant solution is to also suppress the outline on :hover.

a:hover, a:active { outline: none; }

In Conclusion

Of course, many web designers may argue that they know what’s best, even for their keyboard-using audience. Maybe they’ve removed the default outline and are instead providing some carefully designed :focus styles. If they know for sure that these custom styles are indeed a reliable alternative for their users, more power to them… but, at the risk of sounding like Jakob “blue underlined links” Nielsen, I’d still argue that sometimes the default browser behaviours are best left alone. Complemented, yes (and if you’re already defining some fancy styles for :hover, by all means feel free to also make them display on :focus)… but not suppressed.",2009,Patrick Lauke,patricklauke,2009-12-09T00:00:00+00:00,https://24ways.org/2009/dont-lose-your-focus/,code
183,Designing For The Switch,"For a long time on the web, we’ve been typographically spoilt. Yes, you heard me correctly. Think about it: our computers come with web fonts already installed; fonts that have been designed specifically to work well online and at small size; and fonts that we can be sure other people have too. 

Yes, we’ve been spoilt. We don’t need to think about using Verdana, Arial, Georgia or Cambria. 

Yet, for a long time now, designers have felt we needed more. We want to choose whatever typeface we feel necessary for our designs. We did bad things along the way in pursuit of this goal such as images for text. Smart people dreamt up tools to help us such as sIFR, or Cufón. Only fairly recently, @font-face is supported in most browsers. The floodgates are opening. It really is the dawn of a new typographic era on the web. And we must tread carefully. 

The New Typesetters 

Many years ago, before the advent of desktop publishing, if you wanted words set in a particular typeface, you had to go to a Typesetter. A Typesetter, or Compositor, as they were sometimes called, was a person whose job it was to take the written word (in the form of a document or manuscript) and ‘set’ the type in the desired typeface. The designer would chose what typeface they wanted – and all the ligatures, underlines, italics and whatnot – and then scribble all over the manuscript so the typesetter could set the correct type.  

Then along came Desktop Publishing and every Tom, Dick and Harry could choose type on their computer and an entire link in the typographic chain was removed within just a few years. Well, that’s progress I guess. That was until six months ago when Typesetting was reborn on the web in the guise of a font service: Typekit. 

Typekit – and services like Typekit such as Typotheque, Kernest and the upcoming Fontdeck – are typesetting services for the web. You supply them with your content, in the form of a webpage, and they provide you with some JavaScript to render that webpage in the typeface you’ve specified simply by adding the font name in your CSS file. 

Thanks to services like these, font foundries are now talking to create licensing structures to allow us to embed fonts into our web pages legally – which has always been a sticking point in the past. So, finally, us designers can get what we want: whatever typeface we want on the web. 

Yes, but… there are hurdles. One of which is the subject of this article. 

The differences between Web Fonts and other fonts 

Web fonts are different to normal fonts. They differ in a whole bunch of ways, from loose letter spacing to larger x-heights. But perhaps the most notable practical difference is file size. Let’s take a look at one of Typekit’s latest additions from the FontFont library, Meta. 

Meta Roman weighs in at 42 KB. This is a fairly typical file size for a single weight of a good font. Now, let’s have a look at Verdana. Verdana is 186 KB. For one weight. The four weight family for Verdana weighs in at 686 KB. Four weights for half a megabyte!? Why so huge? 

Well, Verdana has a lot of information packed into its 186 KB. It has the largest hinting data table of any typeface (the information carried by a font that tells it how to align itself to the pixels on your screen). As it has been shipped with Microsoft products since 1996, it has had time to grow to support many, many languages. Along with its cousin, Georgia (283 KB), Verdana was a new breed of typeface. And it’s grown fat.  

If really serious web typography takes off – and by that I mean typefaces specifically designed for the screen – then we’re going to see more fonts increase in file size as the font files include more data. So, if you’re embedding a font weighing in at 100 KB, what happens? 

The Flash of Unstyled Text 

We all remember the Flash of Unstyled Content bug on Internet Explorer, right? That annoying bug that caused a momentary flash of unstyled HTML page. Well, the same thing can happen with embedding fonts using @font-face. An effect called The Flash of Unstyled Text (FOUT), first coined by Paul Irish. Personally, I prefer to call it the Flash of UnTypeset Text (still FOUT), as the text is styled, just not with what you want. 

If you embed a typeface in your CSS, then the browser will download that typeface. Typically, browsers differ in the way they handle this procedure. 

Firefox and Opera will render the text using the next font in your font stack until the first (embedded) font is loaded. It will then switch to the embedded font. 

Webkit takes the approach that you asked for that font so it will wait until it’s completely loaded before showing it you. 

In Opera and Firefox, you get a FOUT. In Webkit, you don’t. You wait. 

Hang on there. Didn’t I say that good web fonts weigh in considerably more than ‘normal’ fonts?   And whilst the browser is downloading the font, the user gets what to look at? Some pictures, background colours and whatever else isn’t HTML? I believe Webkit’s handling of font embedding – as deliberate as it is – is damaging to the practice of font embedding. Why? Well, we can design to a switch in typeface (as jarring as that is for the user), but we can’t design to blank space. 

Let’s have a closer look at how we can design to FOUT. 

More considered font stacks 

We all know that font stacks in CSS are there for when a user doesn’t have a font; the browser will jump to the next one in the stack. Adding embedded fonts into the font stack means that because of FOUT (in gecko and Opera), the user can see a switch, and depending on their connection that switch could happen well into any reading that the user may be doing. 

The practicalities of this are that a user could be reading and be towards the end of a line when the paragraph they are reading changes shape. The word they were digesting suddenly changes to three lines down. It’s the online equivalent of someone turning the page for you when you least expect it. So, how can we think about our font stacks slightly differently so we can minimise the switch? 

Two years ago, Richard Rutter wrote on this very site about increasing our font stacks. By increasing the font stacks (by using his handy matrix) we can begin to experiment with different typefaces. However, when we embed a typeface, we must look very carefully at the typefaces in the font stack and the relationship between them. Because, previously, the user would not see a switch from one typeface to another, they’d just get either one or the other. Not both. With FOUT, the user sees two typefaces. 

By carefully looking at the characteristics of the typefaces you choose, you can minimise the typographic ‘distance’ between the type down the stack. In doing so, you minimise the jarring effect of the switch. 

Let’s take a look at an example of how to go about this.  

Micro Typography to build better font stacks 

Let’s say I want to use a recent edition to Typekit – Meta Serif Book – as my embedded font. My font stack would start like this: 

font-family: 'Meta Serif Bold'; 

Where do you go from here? Well, first, familiarise yourself with Richard’s Font Matrix so you get an idea of what fonts are available for different people. Then start by looking closely at the characters of the embedded font and then compare them to different fonts from the matrix. 

When I do this, I’m looking to match type characteristics such as x-height, contrast (the thickness and thinness of strokes), the stress (the angle of contrast) and the shape of the serifs (if the typeface has any). 



Using just these simple comparative metrics means you can get to a ‘best fit’ reasonably quickly. And remember, you’re not after an ideal match. You’re after a match that means the switch is less painful for the reader, but also a typeface that carries similar characteristics so your design doesn’t change too much. 

Building upon my choice of embedded font, I can quickly build up a stack by comparing letters. 



This then creates my ‘best fit’ stack. 



This translates to the CSS as: 

font-family: 'Meta Serif Bold', 'Lucida Bright', Cambria, Georgia, serif 

Following this process, and ending up with considered font stacks, means that we can design to the Flash of UnTypeset Content and ensure that our readers don’t get a diminished experience.",2009,Mark Boulton,markboulton,2009-12-16T00:00:00+00:00,https://24ways.org/2009/designing-for-the-switch/,design
191,CSS Animations,"Friend: You should learn how to write CSS!
Me: …
Friend: CSS; Cascading Style Sheets. If you’re serious about web design, that’s the next thing you should learn.
Me: What’s wrong with <font> tags?

That was 8 years ago. Thanks to the hard work of Jeffrey, Andy, Andy, Cameron, Colly, Dan and many others, learning how to decently markup a website and write lightweight stylesheets was surprisingly easy. They made it so easy even a complete idiot (OH HAI) was able to quickly master it.

And then… nothing. For a long time, it seemed like there wasn’t happening anything in the land of CSS, time stood still. Once you knew the basics, there wasn’t anything new to keep up with. It looked like a great band split, but people just kept re-releasing their music in various “Best Of!” or “Remastered!” albums.

Fast forward a couple of years to late 2006. On the official WebKit blog Surfin’ Safari, there’s an article about something called CSS animations. Great new stuff to play with, but only supported by nightly builds (read: very, very beta) of WebKit. In the following months, they release other goodies, like CSS gradients, CSS reflections, CSS masks, and even more CSS animation sexiness. Whoa, looks like the band got back together, found their second youth, and went into overdrive! The problem was that if you wanted to listen to their new albums, you had to own some kind of new high-tech player no one on earth (besides some early adopters) owned.

Back in the time machine. It is now late 2009, close to Christmas. Things have changed. Browsers supporting these new toys are widely available left and right. Even non-techies are using these advanced browsers to surf the web on a daily basis!

Epic win? Almost, but at least this gives us enough reason to start learning how we could use all this new CSS voodoo. On Monday, Natalie Downe showed you a good tutorial on Going Nuts with CSS Transitions. Today, I’m taking it one step further…

Howto: A basic spinner

No matter how fast internet tubes or servers are, we’ll always need spinners to indicate something’s happening behind the scenes. Up until now, people would go to some site, pick one of the available templates, customize their foreground and background colors, and download a beautiful GIF image.

There are some downsides to this though:


	It’s only _semi_-transparent: If you change your mind and pick a slightly different background color, you need to go back to the site, set all the parameters again, and replace your current image. There isn’t even a way to pick an image or gradient as background.
	Limited number of frames, probable to keep the file-size as small as possible (don’t forget this thing needs to be loaded before whatever process is finished in the background), and you don’t have that 24 frames per second smoothness.
	This is just too fucking easy. As a front-end code geek, there must be a “cooler” way to do this!


What do we need to make a spinner with CSS animations? One image, and one element on our webpage we can hook on to. Yes, that’s it. I created a simple transparent PNG that looks it might be a spinner, and for the element on the page, I wrote this piece of genius HTML:

<p id=""spinner"">Please wait while we do what we do best.</p>

Looks semantic enough to me! Here’s the basic HTML I’m using to position the element in the center of the screen, and make the text inside it disappear:

#spinner {
	position: absolute;
	top: 50%;
	left: 50%;
	margin: -100px 0 0 -100px;
	height: 200px;
	width: 200px;
	text-indent: 250px;
	white-space: nowrap;
	overflow: hidden;
}

Cool, but now we don’t see anything. Let’s pull rabbit number one out of the hat: -webkit-mask-image (accompanied by the previously mentioned transparent PNG image):

#spinner {
	...
	-webkit-mask-image: url(../img/spinner.png);
}

By now you should be feeling like a magician already. Oh, wait, we still have a blank screen, looks like we left something in the hat (tip: not rabbit droppings):

#spinner {
	...
	-webkit-mask-image: url(../img/spinner.png);
	background-color: #000;
}

Nice! What we’ve done right here is telling the element to clip onto the PNG. It’s a lot like clipping layers in Photoshop. So, spinners, they move, right? Into the hat again, and look what we pull out this time: CSS animations!

#spinner {
	...
	-webkit-mask-image: url(../img/spinner.png);
	background-color: #000;
	-webkit-animation-name: spinnerRotate;
	-webkit-animation-duration: 2s;
	-webkit-animation-iteration-count: infinite;
	-webkit-animation-timing-function: linear;
}

Some explanation:


	-webkit-animation-name: Name of the animation we’ll be defining later.
	-webkit-animation-duration: The timespan of the animation.
	-webkit-animation-iteration-count: Repeat once, a defined number of times or infinitely?
	-webkit-animation-timing-function: Linear is the one you’ll be using mostly. Other options are ease-in, ease-out, ease-in-out…


Let’s define spinnerRotate:

@-webkit-keyframes spinnerRotate {
	from {
		-webkit-transform:rotate(0deg);
	}
	to {
		-webkit-transform:rotate(360deg);
	}
}

En Anglais: Rotate #spinner starting at 0 degrees, ending at 360 degrees, over a timespan of 2 seconds, at a constant speed, and keep repeating this animation forever.

That’s it! See it in action on the demo page.

Note: these examples only work when you’re using a WebKit-based browser like Safari, Mobile Safari or Google Chrome. I’m confident though that Mozilla and Opera will try their very best catching up with all this new CSS goodness soon.

When looking at this example, you see the possibilities are endless. Another advantage is you can change the look of it entirely by only changing a couple of lines of CSS, instead of re-creating and re-downloading the image from some website smelling like web 2.0 gone bad. I made another demo that shows how great it is to be able to change background and foreground colors (even on the fly!).

So there you have it, a smoothly animated, fully transparent and completely customizable spinner. Cool? I think so. (Ladies?)

But you can do a lot more with CSS animations than just create pretty spinners. Since I was fooling around with it anyway, I decided to test how far you can push this, space is the final limit, right?

Conclusion

CSS has never been more exciting than it is right now. I’m even prepared to say CSS is “cool” again, both for the more experienced front-end developers as for the new designers discovering CSS every day now.

But…

Remember when Javascript became popular? Remember when Flash became popular? Every time we’re been given new toys, some people aren’t ashamed to use it in a way you can barely call constructive. I’m thinking of Geocities websites, loaded with glowing blocks of text, moving images, bad color usage… In the wise words of Stan Lee: With great power there must also come great responsibility! A sprinkle of CSS animations is better than a bucket load. Apply with care.",2009,Tim Van Damme,timvandamme,2009-12-15T00:00:00+00:00,https://24ways.org/2009/css-animations/,code
192,Cleaner Code with CSS3 Selectors,"The parts of CSS3 that seem to grab the most column inches on blogs and in articles are the shiny bits. Rounded corners, text shadow and new ways to achieve CSS layouts are all exciting and bring with them all kinds of possibilities for web design. However what really gets me, as a developer, excited is a bit more mundane.  

In this article I’m going to take a look at some of the ways our front and back-end code will be simplified by CSS3, by looking at the ways we achieve certain visual effects now in comparison to how we will achieve them in a glorious, CSS3-supported future. I’m also going to demonstrate how we can use these selectors now with a little help from JavaScript – which can work out very useful if you find yourself in a situation where you can’t change markup that is being output by some server-side code.

The wonder of nth-child

So why does nth-child get me so excited? Here is a really common situation, the designer would like the tables in the application to look like this:



Setting every other table row to a different colour is a common way to enhance readability of long rows. The tried and tested way to implement this is by adding a class to every other row. If you are writing the markup for your table by hand this is a bit of a nuisance, and if you stick a row in the middle you have to change the rows the class is applied to. If your markup is generated by your content management system then you need to get the server-side code to add that class – if you have access to that code.

</html>

View Example 1

This situation is something I deal with on almost every project, and apart from being an extra thing to do, it just isn’t ideal having the server-side code squirt classes into the markup for purely presentational reasons. This is where the nth-child pseudo-class selector comes in. The server-side code creates a valid HTML table for the data, and the CSS then selects the odd rows with the following selector:

tr:nth-child(odd) td {
	background-color: #86B486;
}

View Example 2

The odd and even keywords are very handy in this situation – however you can also use a multiplier here. 2n would be equivalent to the keyword ‘odd’ 3n would select every third row and so on.

Browser support

Sadly, nth-child has pretty poor browser support. It is not supported in Internet Explorer 8 and has somewhat buggy support in some other browsers. Firefox 3.5 does have support. In some situations however, you might want to consider using JavaScript to add this support to browsers that don’t have it. This can be very useful if you are dealing with a Content Management System where you have no ability to change the server-side code to add classes into the markup.

I’m going to use jQuery in these examples as it is very simple to use the same CSS selector used in the CSS to target elements with jQuery – however you could use any library or write your own function to do the same job. In the CSS I have added the original class selector to the nth-child selector:

tr:nth-child(odd) td, tr.odd td {
	background-color: #86B486;
}

Then I am adding some jQuery to add a class to the markup once the document has loaded – using the very same nth-child selector that works for browsers that support it. 

<script src=""http://code.jquery.com/jquery-latest.js""></script> 
 <script>
  $(document).ready(function(){
	$(""tr:nth-child(odd)"").addClass(""odd"");
  });
 </script>

View Example 3

We could just add a background colour to the element using jQuery, however I prefer not to mix that information into the JavaScript as if we change the colour on our table rows I would need to remember to change it both in the CSS and in the JavaScript.

Doing something different with the last element

So here’s another thing that we often deal with. You have a list of items all floated left with a right hand margin on each element constrained within a fixed width layout. If each element has the right margin applied the margin on the final element will cause the set to become too wide forcing that last item down to the next row as shown in the below example where I have used a grey border to indicate the fixed width.



Currently we have two ways to deal with this. We can put a negative right margin on the list, the same width as the space between the elements. This means that the extra margin on the final element fills that space and the item doesn’t drop down. 

<!DOCTYPE html PUBLIC ""-//W3C//DTD XHTML 1.0 Strict//EN""

	}
	div#wrapper {
		width: 740px;
		float: left;
		border: 5px solid #ccc;
	}
	ul.gallery {
		margin: 0 -10px 0 0;
		padding: 0;
		list-style: none;
	}
	ul.gallery li {
		float: left;
		width: 240px;
		margin: 0 10px 10px 0;
	}
</style>
</head>
<body>
	<div id=""wrapper"">
		<ul class=""gallery"">
			<li><img src=""xmas1.jpg"" alt=""baubles"" /></li>
			<li><img src=""xmas2.jpg"" alt=""star"" /></li>
			<li><img src=""xmas3.jpg"" alt=""wreath"" /></li>
		</ul>
	</div>
</body>
</html>

View Example 4

The other solution will be to put a class on the final element and in the CSS remove the margin for this class. 

ul.gallery li.last {
	margin-right: 0;
}

This second solution may not be easy if the content is generated from server-side code that you don’t have access to change.

It could all be so different. In CSS3 we have marvellously common-sense selectors such as last-child, meaning that we can simply add rules for the last list item. 

ul.gallery li:last-child {
	margin-right: 0;
}

View Example 5

This removed the margin on the li which is the last-child of the ul with a class of gallery. No messing about sticking classes on the last item, or pushing the width of the item out wit a negative margin.

If this list of items repeated ad infinitum then you could also use nth-child for this task. Creating a rule that makes every 3rd element margin-less.

ul.gallery li:nth-child(3n) {
	margin-right: 0;
}

View Example 6



A similar example is where the designer has added borders to the bottom of each element – but the last item does not have a border or is in some other way different. Again, only a class added to the last element will save you here if you cannot rely on using the last-child selector.

Browser support for last-child

The situation for last-child is similar to that of nth-child, in that there is no support in Internet Explorer 8. However, once again it is very simple to replicate the functionality using jQuery. Adding our .last class to the last list item.

$(""ul.gallery li:last-child"").addClass(""last"");

We could also use the nth-child selector to add the .last class to every third list item.

$(""ul.gallery li:nth-child(3n)"").addClass(""last"");

View Example 7

Fun with forms

Styling forms can be a bit of a trial, made difficult by the fact that any CSS applied to the input element will effect text fields, submit buttons, checkboxes and radio buttons. As developers we are left adding classes to our form fields to differentiate them. In most builds all of my text fields have a simple class of text whereas I wouldn’t dream of adding a class of para to every paragraph element in a document.

Attribute selectors provide a way of targeting elements by looking at the attributes of those elements. Unlike the other examples in this article which are CSS3 selectors, the attribute selector is actually a CSS2.1 selector – it just doesn’t get much use because of lack of support in Internet Explorer 6. Using attribute selectors we can write rules for text inputs and form buttons without needing to add any classes to the markup. For example after removing the text and button classes from my text and submit button input elements I can use the following rules to target them:

form input[type=""text""] {
    border: 1px solid #333;
    padding: 0.2em;
    width: 400px;
}
form input[type=""submit""]{
    border: 1px solid #333;
    background-color: #eee;
    color: #000;
    padding: 0.1em;
} 

View Example 9

Another problem that I encounter with forms is where I am using CSS to position my labels and form elements by floating the labels. This works fine as long as I want all of my labels to be floated, however sometimes we get a set of radio buttons or a checkbox, and I don’t want the label field to be floated. As you can see in the below example the label for the checkbox is squashed up into the space used for the other labels, yet it makes more sense for the checkbox to display after the text.



I could use a class on this label element however CSS3 lets me to target the label attribute directly by looking at the value of the for attribute.

label[for=""fOptIn""] {
    float: none;
    width: auto;
}



Being able to precisely target attributes in this way is incredibly useful, and once IE6 is no longer an issue this will really help to clean up our markup and save us from having to create all kinds of special cases when generating this markup on the server-side.

Browser support

The news for attribute selectors is actually pretty good with Internet Explorer 7+, Firefox 2+ and all other modern browsers all having support. As I have already mentioned this is a CSS2.1 selector and so we really should expect to be able to use it as we head into 2010! Internet Explorer 7 has slightly buggy support and will fail on the label example shown above however I discovered a workaround in the Sitepoint CSS reference comments. Adding the selector label[htmlFor=""fOptIn""] to the correct selector will create a match for IE7.

IE6 does not support these selector but, once again, you can use jQuery to plug the holes in IE6 support. The following jQuery will add the text and button classes to your fields and also add a checks class to the label for the checkbox, which you can use to remove the float and width for this element.

$('form input[type=""submit""]').addClass(""button"");
$('form input[type=""text""]').addClass(""text"");
$('label[for=""fOptIn""]').addClass(""checks"");

View Example 10

The selectors I’ve used in this article are easy to overlook as we do have ways to achieve these things currently. As developers – especially when we have frameworks and existing code that cope with these situations – it is easy to carry on as we always have done. 

I think that the time has come to start to clean up our front and backend code and replace our reliance on classes with these more advanced selectors. With the help of a little JavaScript almost all users will still get the full effect and, where we are dealing with purely visual effects, there is definitely a case to be made for not worrying about the very small percentage of people with old browsers and no JavaScript. They will still receive a readable website, it may just be missing some of the finesse offered to the modern browsing experience.",2009,Rachel Andrew,rachelandrew,2009-12-20T00:00:00+00:00,https://24ways.org/2009/cleaner-code-with-css3-selectors/,code
182,Breaking Out The Edges of The Browser,"HTML5 contains more than just the new entities for a more meaningful document, it also contains an arsenal of JavaScript APIs.  So many in fact, that some APIs have outgrown the HTML5 spec’s backyard and have been sent away to grow up all on their own and been given the prestigious honour of being specs in their own right.

So when I refer to (bendy finger quote) “HTML5”, I mean the HTML5 specification and a handful of other specifications that help us authors build web applications.

Examples of those specs I would include in the umbrella term would be: geolocation, web storage, web databases, web sockets and web workers, to name a few.

For all you guys and gals, on this special 2009 series of 24 ways, I’m just going to focus on data storage and offline applications: boldly taking your browser where no browser has gone before!

Web Storage

The Web Storage API is basically cookies on steroids, a unhealthy dosage of steroids.  Cookies are always a pain to work with.  First of all you have the problem of setting, changing and deleting them.  Typically solved by Googling and blindly relying on PPK’s solution.  If that wasn’t enough, there’s the 4Kb limit that some of you have hit when you really don’t want to.

The Web Storage API gets around all of the hoops you have to jump through with cookies.  Storage supports around 5Mb of data per domain (the spec’s recommendation, but it’s open to the browsers to implement anything they like) and splits in to two types of storage objects:


	sessionStorage – available to all pages on that domain while the window remains open
	localStorage – available on the domain until manually removed


Support

Ignoring beta browsers for our support list, below is a list of the major browsers and their support for the Web Storage API:


	Latest: Internet Explorer, Firefox, Safari (desktop & mobile/iPhone)
	Partial: Google Chrome (only supports localStorage)
	Not supported: Opera (as of 10.10)


Usage

Both sessionStorage and localStorage support the same interface for accessing their contents, so for these examples I’ll use localStorage.

The storage interface includes the following methods:


	setItem(key, value)
	getItem(key)
	key(index)
	removeItem(key)
	clear()


In the simple example below, we’ll use setItem and getItem to store and retrieve data:

localStorage.setItem('name', 'Remy');
alert( localStorage.getItem('name') );

Using alert boxes can be a pretty lame way of debugging.  Conveniently Safari (and Chrome) include database tab in their debugging tools (cmd+alt+i), so you can get a visual handle on the state of your data:

 Viewing localStorage

As far as I know only Safari has this view on stored data natively in the browser.  There may be a Firefox plugin (but I’ve not found it yet!) and IE… well that’s just IE.

Even though we’ve used setItem and getItem, there’s also a few other ways you can set and access the data.

In the example below, we’re accessing the stored value directly using an expando and equally, you can also set values this way:

localStorage.name = ""Remy"";
alert( localStorage.name ); // shows ""Remy""

The Web Storage API also has a key method, which is zero based, and returns the key in which data has been stored. This should also be in the same order that you set the keys, for example:

alert( localStorage.getItem(localStorage.key(0)) ); 
// shows ""Remy""

I mention the key() method because it’s not an unlikely name for a stored value.  This can cause serious problems though.

When selecting the names for your keys, you need to be sure you don’t take one of the method names that are already on the storage object, like key, clear, etc. As there are no warnings when you try to overwrite the methods, it means when you come to access the key() method, the call breaks as key is a string value and not a function.

You can try this yourself by creating a new stored value using localStorage.key = ""foo"" and you’ll see that the Safari debugger breaks because it relies on the key() method to enumerate each of the stored values.

Usage Notes

Currently all browsers only support storing strings. This also means if you store a numeric, it will get converted to a string:

localStorage.setItem('count', 31);
alert(typeof localStorage.getItem('count')); 
// shows ""string""

This also means you can’t store more complicated objects natively with the storage objects.  To get around this, you can use Douglas Crockford’s JSON parser (though Firefox 3.5 has JSON parsing support baked in to the browser – yay!) json2.js to convert the object to a stringified JSON object:

var person = {
	name: 'Remy',
	height: 'short',
	location: 'Brighton, UK'
};
localStorage.setItem('person', JSON.stringify(person));
alert( JSON.parse(localStorage.getItem('person')).name ); 
// shows ""Remy""

Alternatives

There are a few solutions out there that provide storage solutions that detect the Web Storage API, and if it’s not available, fall back to different technologies (for instance, using a flash object to store data).  One comprehensive version of this is Dojo’s storage library.  I’m personally more of a fan of libraries that plug missing functionality under the same namespace, just as Crockford’s JSON parser does (above).

For those interested it what that might look like, I’ve mocked together a simple implementation of sessionStorage.  Note that it’s incomplete (because it’s missing the key method), and it could be refactored to not using the JSON stringify (but you would need to ensure that the values were properly and safely encoded):

// requires json2.js for all browsers other than Firefox 3.5
if (!window.sessionStorage && JSON) {
	window.sessionStorage = (function () {
		// window.top.name ensures top level, and supports around 2Mb
		var data = window.top.name ? JSON.parse(window.top.name) : {};
		return {    
			setItem: function (key, value) {
				data[key] = value+""""; // force to string
				window.top.name = JSON.stringify(data);
			},
			removeItem: function (key) {
				delete data[key];
				window.top.name = JSON.stringify(data);        
			},
			getItem: function (key) {
				return data[key] || null;
			},
			clear: function () {
				data = {};
				window.top.name = '';
			}
		};
	})();
}

Now that we’ve cracked the cookie jar with our oversized Web Storage API, let’s have a look at how we take our applications offline entirely.

Offline Applications

Offline applications is (still) part of the HTML5 specification.  It allows developers to build a web app and have it still function without an internet connection.  The app is access via the same URL as it would be if the user were online, but the contents (or what the developer specifies) is served up to the browser from a local cache. From there it’s just an everyday stroll through open web technologies, i.e. you still have access to the Web Storage API and anything else you can do without a web connection.

For this section, I’ll refer you to a prototype demo I wrote recently of a contrived Rubik’s cube (contrived because it doesn’t work and it only works in Safari because I’m using 3D transforms).

 Offline Rubik’s cube

Support

Support for offline applications is still fairly limited, but the possibilities of offline applications is pretty exciting, particularly as we’re seeing mobile support and support in applications such as Fluid (and I would expect other render engine wrapping apps).

Support currently, is as follows:


	Latest: Safari (desktop & mobile/iPhone)
	Sort of: Firefox‡
	Not supported: Internet Explorer, Opera, Google Chrome


‡ Firefox 3.5 was released to include offline support, but in fact has bugs where it doesn’t work properly (certainly on the Mac), Minefield (Firefox beta) has resolved the bug.

Usage

The status of the application’s cache can be tested from the window.applicationCache object.  However, we’ll first look at how to enable your app for offline access.

You need to create a manifest file, which will tell the browser what to cache, and then we point our web page to that cache:

<!DOCTYPE html>
<html manifest=""remy.manifest"">
<!-- continues ... -->

For the manifest to be properly read by the browser, your server needs to serve the .manifest files as text/manifest by adding the following to your mime.types:

text/cache-manifest  manifest

Next we need to populate our manifest file so the browser can read it:

CACHE MANIFEST
/demo/rubiks/index.html
/demo/rubiks/style.css
/demo/rubiks/jquery.min.js
/demo/rubiks/rubiks.js
# version 15

The first line of the manifest must read CACHE MANIFEST.  Then subsequent lines tell the browser what to cache.

The HTML5 spec recommends that you include the calling web page (in my case index.html), but it’s not required.  If I didn’t include index.html, the browser would cache it as part of the offline resources.

These resources are implicitly under the CACHE namespace (which you can specify any number of times if you want to).

In addition, there are two further namespaces: NETWORK and FALLBACK.

NETWORK is a whitelist namespace that tells the browser not to cache this resource and always try to request it through the network.

FALLBACK tells the browser that whilst in offline mode, if the resource isn’t available, it should return the fallback resource.

Finally, in my example I’ve included a comment with a version number.  This is because once you include a manifest, the only way you can tell the browser to reload the resources is if the manifest contents changes. So I’ve included a version number in the manifest which I can change forcing the browser to reload all of the assets.

How it works

If you’re building an app that makes use of the offline cache, I would strongly recommend that you add the manifest last. The browser implementations are very new, so can sometimes get a bit tricky to debug since once the resources are cached, they really stick in the browser.

These are the steps that happen during a request for an app with a manifest:


	Browser: sends request for your app.html
	Server: serves all associated resources with app.html – as normal
	Browser: notices that app.html has a manifest, it re-request the assets in the manifest
	Server: serves the requested manifest assets (again)
	Browser: window.applicationCache has a status of UPDATEREADY
	Browser: reloads
	Browser: only request manifest file (which doesn’t show on the net requests panel)
	Server: responds with 304 Not Modified on the manifest file
	Browser: serves all the cached resources locally


What might also add confusion to this process, is that the way the browsers work (currently) is if there is a cache already in place, it will use this first over updated resources.  So if your manifest has changed, the browser will have already loaded the offline cache, so the user will only see the updated on the next reload.  

This may seem a bit convoluted, but you can also trigger some of this manually through the applicationCache methods which can ease some of this pain.

If you bind to the online event you can manually try to update the offline cache. If the cache has then updated, swap the updated resources in to the cache and the next time the app loads it will be up to date.  You could also prompt your user to reload the app (which is just a refresh) if there’s an update available.

For example (though this is just pseudo code):

addEvent(applicationCache, 'updateready', function () {
	applicationCache.swapCache();
	tellUserToRefresh();
});
addEvent(window, 'online', function () {
	applicationCache.update();
});

Breaking out of the Browser

So that’s two different technologies that you can use to break out of the traditional browser/web page model and get your apps working in a more application-ny way.

There’s loads more in the HTML5 and non-HTML5 APIs to play with, so take your Christmas break to check them out!",2009,Remy Sharp,remysharp,2009-12-02T00:00:00+00:00,https://24ways.org/2009/breaking-out-the-edges-of-the-browser/,code
170,"A Pet Project is For Life, Not Just for Christmas","I’m excited: as December rolls on, I’m winding down from client work and indulging in a big pet project I’ve been dreaming up for quite some time, with the aim of releasing it early next year. I’ve always been a bit of a sucker for pet projects and currently have a few in the works: the big one, two collaborations with friends, and my continuing (and completely un-web-related) attempt at music. But when I think about the other designers and developers out there whose work I admire, one thing becomes obvious: they’ve all got pet projects! Look around the web and you’ll see that anyone worth their salt has some sort of side project on the go. If you don’t have yours yet, now’s the time!

Have a pet project to collaborate with your friends

It’s not uncommon to find me staring at my screen, looking at beautiful websites my friends have made, grinning inanely because I feel so honoured to know such talented individuals. But one thing really frustrates me: I hardly ever get to work with these people! Sure, there are times when it’s possible to do so, but due to various project situations, it’s a rarity.

So, in order to work with my friends, I’ve found the best way is to instigate the collaboration outside of client work; in other words, have a pet project together! Free from the hard realities of budgets, time restraints, and client demands, you and your friends can come up with something purely for your own pleasures. If you’ve been looking for an excuse to work with other designers or developers whose work you love, the pet project is that excuse. They don’t necessarily have to be friends, either: if the respect is mutual, it can be a great way of breaking the ice and getting to know someone. 

 Figure 1: A forthcoming secret love-child from myself and Tim Van Damme

Have a pet project to escape from your day job

We all like to moan about our clients and bosses, don’t we? But if leaving your job or firing your evil client just isn’t an option, why not escape from all that and pour your creative energies into something you genuinely enjoy? 

It’s not just about reacting to negativity, either: a pet project is a great way to give yourself a bit of variety. As web designers, our day-to-day work forces us to work within a set of web-related contraints and sometimes it can be demoralising to spend so many hours fixing IE bugs. The perfect antidote? Go and do some print design! If it’s not possible in your day job or client work, the pet project is the perfect place to exercise your other creative muscles. Yes, print design (or your chosen alternative) has its own constraints, but if they’re different to those you experience on a daily basis, it’ll be a welcome relief and you’ll return to your regular work feeling refreshed.

Have a pet project to fulfill your own needs

Many pet projects come into being because the designers and/or developers behind them are looking for a tool to accomplish a task and find that it doesn’t exist, thus prompting them to create their own solution. In fact, the very app I’m using to write this article — Ommwriter, from Herraiz Soto & Co — was originally a tool they’d created for their internal staff, before releasing it to the public so that it could be enjoyed by others.

Just last week, Tina Roth Eisenberg launched Teux Deux, a pet project she’d designed to meet her own requirements for a to-do list, having found that no existing apps fulfilled her needs. Oh, and it was a collaboration with her studio mate Cameron. Remember what I was saying about working with your friends?

 Figure 3: Teux Deux, the GTD pet project that launched just last week

Have a pet project to help people out

Ommwriter and Teux Deux are free for anyone to use. Let’s just think about that for a moment: the creators have invested their time and effort in the project, and then given it away to be used by others. That’s very cool and something we’re used to seeing a lot of in the web community (how lucky we are)! People love free stuff and giving away the fruits of your labour will earn you major kudos. Of course, there’s nothing wrong with making some money, either — more on that in a second.

 Figure 4: Dan Rubin‘s extremely helpful Make Photoshop Faster

Have a pet project to raise your profile

So, giving away free stuff earns you kudos. And kudos usually helps you raise your profile in the industry. We all like a bit of shameless fame, don’t we? But seriously, if you want to become well known, make something cool. It could be free (to buy you the love and respect of the community) or it could be purchasable (if you’ve made something that’s cool enough to deserve hard-earned cash), but ultimately it needs to be something that people will love. 

 Figure 5: Type designer Jos Buivenga has shot to fame thanks to his beautiful typefaces and ‘freemium’ business model

If you’re a developer with no design skills, team up with a good designer so that the design community appreciate its aesthetic. If you’re a designer with no development skills, team up with a good developer so that it works. Oh, and not that I’d recommend you ever do this for selfish reasons, but collaborating with someone you admire — whose work is well-respected by the community — will also help raise your profile.

Have a pet project to make money

In spite of our best hippy-esque intentions to give away free stuff to the masses, there’s also nothing wrong with making a bit of money from your pet project. In fact, if your project involves you having to make a considerable financial investment, it’s probably a good idea to try and recoup those costs in some way.

 Figure 6: The success of Shaun Inman‘s various pet projects — Mint, Fever, Horror Vacui, etc. — have allowed him to give up client work entirely.

A very common way to do that in both the online and offline worlds is to get some sort of advertising. For a slightly different approach, try contacting a company who are relevant to your audience and ask them if they’d be interesting in sponsoring your project, which would usually just mean having their brand associated with yours in some way. This is still a form of advertising but tends to allow for a more tasteful implementation, so it’s worth pursuing. 

Advertising is a great way to cover your own costs and keep things free for your audience, but when costs are considerably higher (like if you’re producing a magazine with high production values, for instance), there’s nothing wrong with charging people for your product. But, as I mentioned above, you’ve got to be positive that it’s worth paying for!

Have a pet project just for fun

Sometimes there’s a very good reason for having a pet project — and sometimes even a viable business reason — but actually you don’t need any reason at all. Wanting to have fun is just as worthy a motivation, and if you’re not going to have fun doing it, then what’s the point? Assuming that almost all pet projects are designed, developed, written, printed, marketed and supported in our free time, why not do something enjoyable?

In conclusion

The fact that you’re reading 24 ways shows that you have a passion for the web, and that’s something I’m happy to see in abundance throughout our community. Passion is a term that’s thrown about all over the place, but it really is evident in the work that people do. It’s perhaps most evident, however, in the pet projects that people create. Don’t forget that the very site you’re reading this article on is… a pet project.

If you’ve yet to do so, make it a new year’s resolution for 2010 to have your own pet project so that you can collaborate with your friends, escape from your day job, fulfil your own needs, help people out, raise your profile, make money, and — above all — have fun.",2009,Elliot Jay Stocks,elliotjaystocks,2009-12-18T00:00:00+00:00,https://24ways.org/2009/a-pet-project-is-for-life-not-just-for-christmas/,business
187,A New Year's Resolution,"The end of 2009 is fast approaching.  Yet another year has passed in a split second. Our Web Designing careers are one year older and it’s time to reflect on the highs and lows of 2009. What was your greatest achievement and what could you have done better? Perhaps, even more importantly, what are your goals for 2010?

Something that I noticed in 2009 is that being a web designer 24/7; it’s easy to get consumed by the web. It’s easy to get caught up in the blog posts, CSS galleries, web trends and Twitter!  Living in this bubble can lead to one’s work becoming stale, boring and basically like everyone else’s work on the web. No designer wants this.

So, I say on 1st January 2010 let’s make it our New Year’s resolution to create something different, something special or even ground-breaking! Make it your goal to break the mold of current web design trends and light the way for your fellow web designer comrades!

Of course I wouldn’t let you embark on the New Year empty handed. To help you on your way I’ve compiled a few thoughts and ideas to get your brains ticking!

Don’t design for the web, just design

A key factor in creating something original and fresh for the web is to stop thinking in terms of web design. The first thing we need to do is forget the notion of headers, footers, side bars etc. A website doesn’t necessarily need any of these, so even before we’ve started we’ve already limited our design possibilities by thinking in these very conventional and generally accepted web terms. The browser window is a 2D canvas like any other and we can do with it what we like. 

With this in mind we can approach web design from a fresh perspective. We can take inspiration for web design from editorial design, packaging design, comics, poster design, album artwork, motion design, street signage and anything else you can think of. Web design is way more than the just the web and by taking this more wide angled view of what web design is and can be you’ll find there are a thousand more exiting design possibilities.

Note: Try leaving the wire framing till after you’ve gone to town with some initial design concepts. You might find it helps keep your head out of that ‘web space’ a little bit longer, thus enabling you to think more freely about your design. Really go crazy with these as you can always pull it back into line later. The key is to think big initially and then work backwards. There’s no point restricting your creativity early on because your technical knowledge can foresee problems down the line. You can always sort these problems out later on… let your creative juices flow!

 Inspiration can come from anywhere! (Photo: modomatic)

Try something new!

Progress in web design or in any design discipline is a sort of evolution. Design trends and solutions merge and mutate to create new design trends and hopefully better solutions. This is fine but the real leaps are made when someone has the guts to do something different. 

Don’t be afraid to challenge the status quo. To create truly original work you have to be prepared to get it wrong and that’s hard to do. When you’re faced with this challenge just remind yourself that in web design there is rarely a ‘best way to do something’, or why would we ever do it any other way? 

If you do this and get it right the pay off can be immense. Not only will you work stand out from the crowd by a mile, you will have become a trend setter as opposed to a trend follower.

Tell a story with your design

Great web design is way more than just the aesthetics, functionality or usability. Great web design goes beyond the pixels on the screen. For your website to make a real impact on it’s users it has to connect with them emotionally. So, whether your website is promoting your own company or selling cheese it needs to move people. You need to weave a story into your design. It’s this story that your users will connect with. 

To do this the main ingredients of your design need to be strongly connected. In my head those main ingredients are Copy, Graphic Design, Typography, imagery and colour. 

Copy

Strong meaningful copy is the backbone to most great web design work. Pay special attention to strap lines and headlines as these are often the sparks that start the fire. All the other elements can be inspired by this backbone of strong copy.

Graphic Design

Use the copy to influence how you treat the page with your graphic design. Let the design echo the words.

Typography

What really excites me about typography isn’t the general text presentation on a page, most half decent web designer have a grasp of this already. What excites me is the potential there is to base a whole design on words and letters. Using the strong copy you already have, one has the opportunity the customise, distort, build and arrange words and letters to create beautiful and powerful compositions that can be the basis for an entire site design.

 Get creative with Typography (Photo: Pam Sattler)

Imagery and Colour

With clever use of imagery (photographs or illustrations) and colour you further have the chance to deepen the story you are weaving into your design. The key is to use meaningful imagery, don’t to insert generic imagery for the sake of filling space… it’s just a wasted opportunity.

Remember, the main elements of your design combined are greater than the sum of their parts. Whatever design decisions you make on a page, make them for a good reason. It’s not good enough to try and seduce your users with slick and shiny web pages. For your site to leave a lasting impression on the user you need to make that emotional connection.

 Telling the Story (Advertising Agency: Tita, Milano, Italy, Art Director: Emanuele Basso)

Go one step further

So you’ve almost finished your latest website design. You’ve fulfilled the brief, you’re happy with the result and you’re pretty sure your client will be too. It’s at this point we should ask ourselves “Can I push this further”? What touches could you add to the site that’ll take it beyond what was required and into something exceptional? The truth is, to produce exceptional work we need to do more than is required of us. We need to answer the brief and then some!

Go back through your site and make a note of what enhancements could be made to make the site not just good but outstanding. It might be revisiting a couple of pages that were neglected in the design process, it might be adding some CSS 3 gloss for the users that can benefit from it or it might just be adding some clever little easter eggs to show that you care. These touches will soon add up and make a massive difference to the finished product.

So, go one step further… take it further than you anyone else will. Then your work will stand out for sure.

Parting message

I love being a designer for many of reasons but the main one being that with every new project we embark on we have the chance to express ourselves. We have the chance to create something special, something that people will talk about. It’s this chance that drives us onwards day after day, year after year. So in 2010 shout louder than you ever have before, take chances, try something new and above all design your socks off!",2009,Mike Kus,mikekus,2009-12-10T00:00:00+00:00,https://24ways.org/2009/a-new-years-resolution/,business
113,What Your Turkey Can Teach You About Project Management,"The problem with project management is that everyone thinks it’s boring. Well, that’s not really the problem. The problem is that everyone thinks it’s boring but it’s still really important. Project management is what lets you deliver your art – whether that be design or development. 

In the same way, a Christmas dinner cooked by a brilliant chef with no organizational skills is disastrous – courses arrive in the wrong order, some things are cold whilst others are raw and generally it’s a trip to the ER waiting to happen. Continuing the Christmas dinner theme, here are my top tips for successful projects, wrapped up in a nice little festive analogy. Enjoy!

Tip 1: Know What You’re Aiming For

(Turkey? Ham? Both??)

The underlying cause for the failure of so many projects is mismatched expectations. Christmas dinner cannot be a success if you serve glazed ham and your guests view turkey as the essential Christmas dinner ingredient. It doesn’t matter how delicious and well executed your glazed ham is, it’s still fundamentally just not turkey. You might win one or two adventurous souls over, but the rest will go home disappointed.

Add to the mix the fact that most web design projects are nowhere near as emotive as Christmas dinner (trust me, a ham vs turkey debate will rage much longer than a fixed vs fluid debate in normal human circles) and the problem is compounded. In particular, as technologists, we forget that our ability to precisely imagine the outcome of a project, be it a website, a piece of software, or similar, is much more keenly developed than the average customer of such projects. 

So what’s the solution? Get very clear, from the very beginning, on exactly what the project is about. What are you trying to achieve? How will you measure success? Is the presence of turkey a critical success factor?

Summarize all this information in some form of document (in PM-speak, it’s called a Project Initiation Document typically). Ideally, get the people who are the real decision makers to sign their agreement to that summary in their own blood. Well, you get the picture, I suppose actual blood is not strictly necessary, but a bit of gothic music to set the tone can be useful!

Tip 2: Plan at the Right Level of Detail

Hugely detailed and useless Gantt charts are a personal bugbear of mine. For any project, you should plan at the appropriate level of detail (and in an appropriate format) for the project itself. In our Christmas dinner example, it may be perfectly fine to have a list of tasks for the preparation work, but for the intricate interplay of oven availability and cooking times, something more complex is usually due. Having cooked roast dinners for fourteen in a student house where only the top oven and two of the rings on the hob actually worked, I can attest to the need for sequence diagrams in some of these situations!

The mistake many small teams make is to end up with a project plan that is really the amalgamation of their individual todo lists. What is needed is a project plan that will:


	reflect reality
	be easy to update
	help to track progress (i.e. are we on track or not?)


A good approach is to break your project into stages (each representing something tangible) and then into deliverables (again, something tangible for each milestone, else you’ll never know if you’ve hit it or not!). 

My personal rule of thumb is that the level of granularity needed on most projects is 2-3 days – i.e. we should never be more than two to three days from a definitive milestone which will either be complete or not. The added advantage of this approach is that if find yourself off track, you can only be two to three days off track… much easier to make up than if you went weeks or even months working hard but not actually delivering what was needed!

In our Christmas dinner example, there are a number of critical milestones – a tick list of questions. Do we have all the ingredients? Check. Has the turkey been basted? Check. On the actual day, the sequencing and timing will mean more specific questions: It’s 12pm. Are the Brussels sprouts cooked to death yet? Check. (Allowing for the extra hour of boiling to go from soft and green to mushy and brown… Yeuch!) 

Tip 3: Actively Manage Risks and Issues

A risk is something that could go wrong. An issue is something that has already gone wrong. Risks and issues are where project management superstars are born. Anyone can manage things when everything is going according to plan; it’s what you do when Cousin Jim refuses to eat anything but strawberry jam sandwiches that sorts the men from the boys. 

The key with a Christmas dinner, as with any project, is to have contingency plans for the most likely and most damaging risks. These depend on your own particular situation, but some examples might be:

 
		
			RISK
			CONTINGENCY PLAN
		
		
			Cousin Jim is a picky eater.
			Have strawberry jam and sliced white bread on hand to placate.
		
		
			Prime organic turkey might not be available at Waitrose on Christmas eve.
			Shop in advance!
		
		
			You live somewhere remote that seems to lose power around Christmas on a disturbingly regular basis.
			(number of options here depending on how far you want to go…)

					Buy a backup generator.

					Invent a new cooking method using only candles.

					Stock up on “Christmas dinner in a tin”.
		
		
			Your mother in law is likely to be annoying.
			Bottle of sherry at the ready (whether it’s for you or her, you can decide!).
		
 


The point of planning in advance is so that most of your issues don’t blindside you – you can spring into action with the contingency plan immediately. This leaves you with plenty of ingenuity and ability to cope in reserve for those truly unexpected events. 

Back in your regular projects, you should have a risk management plan (developed at the beginning of the project and regularly reviewed) as well as an issue list, tracking open, in progress and closed issues. Importantly, your issue list should be separate from any kind of bug list – issues are at a project level, bugs are at a technical level.

Tip 4: Have a Project Board

A project board consists of the overall sponsor of your project (often, but not always, the guy with the cheque book) and typically a business expert and a technical expert to help advise the sponsor. The project board is the entity that is meant to make the big, critical decisions. As a project manager, your role is to prepare a recommendation, but leave the actual decision up to the board. 

Admittedly this is where our Christmas dinner analogy has to stretch the most, but if you imagine that instead of just cooking for your family you are the caterer preparing a Christmas feast for a company. In this case, you obviously want to please the diners who will be eating the food, but key decisions are likely to be taken by whoever is organizing the event. They, in turn, will involve the boss if there are really big decisions that would affect the project drastically – for instance, having to move it to January, or it exceeding the set budget by a significant amount.

Most projects suffer from not having a project board to consult for these major decisions, or from having the wrong people selected. The first ailment is eased by ensuring that you have a functioning project board, with whom you either meet regularly to update on status, or where there is a special process for convening the board if they are needed. The second problem is a little more subtle. Key questions to ask yourself are:


	Who is funding this project?
	Who has the authority to stop the project if it was the right thing to do?
	Who are the right business and technical advisors?
	Who are the folks who don’t look like they are powerful on the org chart, but in fact might scupper this project? (e.g. administrators, tech support, personal assistants…)


Tip 5: Finish Unequivocably and Well

No one is ever uncertain as to when Christmas dinner ends. Once the flaming pudding has been consumed and the cheese tray picked at, the end of the dinner is heralded by groaning and everyone collapsing in their chairs. Different households have different rituals, so you might only open your presents after Christmas dinner (unlikely if you have small children!), or you might round off the afternoon watching the Queen’s speech (in Britland, certainly) or if you live in warmer climes you might round off Christmas dinner with a swim (which was our tradition in Cape Town – after 30 mins of food settling so you didn’t get cramp, of course!). 

The problem with projects is that they are one time efforts and so nowhere near as ritualized. Unless you have been incredibly lucky, you’ve probably worked on a project where you thought you were finished but seemed unable to lose your “zombie customers” – those folks who just didn’t realise it was over and kept coming back with more and more requests. You might even have fallen prey to this yourself, believing that the website going live was the end of the project and not realising that a number of things still needed to be wrapped up.

The essence of this final tip is to inject some of that end-of-Christmas finality ritual into your projects. Find your own ritual for closing down projects – more than just sending the customer the invoice and archiving the files. Consider things like documentation, support structure handover and training to make sure that those zombies are going to the right people (hopefully not you!). 

So, to summarise:


	Make sure you start your projects well – with an agreed (written) vision of what you’re trying to achieve.

107,Using Google App Engine as Your Own Content Delivery Network,"Do you remember, years ago, when hosting was expensive, domain names were the province of the rich, and you hosted your web pages on Geocities? It seems odd to me now that there was a time when each and every geek didn’t have his own top-level domain and super hosting setup. But as the parts became more and more affordable a man could become an outcast if he didn’t have his own slightly surreal-sounding TLD.

And so it will be in the future when people realise with surprise there was a time before affordable content delivery networks.

A content delivery network, or CDN, is a system of servers spread around the world, serving files from the nearest physical location. Instead of waiting for a file to find its way from a server farm in Silicon Valley 8,000 kilometres away, I can receive it from London, Dublin, or Paris, cutting down the time I wait. The big names — Google, Yahoo, Amazon, et al — use CDNs for their sites, but they’ve always been far too expensive for us mere mortals. Until now.

There’s a service out there ready for you to use as your very own CDN. You have the company’s blessing, you won’t need to write a line of code, and — best of all — it’s free. The name? Google App Engine.

In this article you’ll find out how to set up a CDN on Google App Engine. You’ll get the development software running on your own computer, tell App Engine what files to serve, upload them to a web site, and give everyone round the world access to them.

Creating your first Google App Engine project

Before we do anything else, you’ll need to download the Google App Engine software development kit (SDK). You’ll need Python 2.5 too — you won’t be writing any Python code but the App Engine SDK will need it to run on your computer. If you don’t have Python, App Engine will install it for you (if you use Mac OS X 10.5 or a Linux-based OS you’ll have Python; if you use Windows you won’t).

Done that? Excellent, because that’s the hardest step. The rest is plain sailing.

You’ll need to choose a unique ‘application id’ — nothing more than a name — for your project. Make sure it consists only of lowercase letters and numbers. For this article I’ll use 24ways2008, but you can choose anything you like.

On your computer, create a folder named after your application id. This folder can be anywhere you want: your desktop, your documents folder, or wherever you usually keep your web files. Within your new folder, create a folder called assets, and within that folder create three folders called images, css, and javascript. These three folders are the ones you’ll fill with files and serve from your content delivery network. You can have other folders too, if you like.

That will leave you with a folder structure like this:

24ways2008/
		assets/
			css/
			images/
			javascript/

Now you need to put a few files in these folders, so we can later see our CDN in action. You can put anything you want in these folders, but for this example we’ll include an HTML file, a style sheet, an image, and a Javascript library.

In the top-level folder (the one I’ve called 24ways2008), create a file called index.html. Fill this with any content you want. In the assets/css folder, create a file named core.css and throw in a couple of CSS rules for good measure. In the assets/images directory save any image that takes your fancy — I’ve used the silver badge from the App Engine download page. Finally, to fill the JavaScript folder, add in this jQuery library file. If you’ve got the time and the inclination, you can build a page that uses all these elements.

So now we should have a set of files and folders that look something like this:

24ways2008/
		assets/
				index.html
				css/
						core.css
				images/
						appengine-silver-120x30.gif
				javascript/
						jquery-1.2.6.min.js

Which leaves us with one last file to create. This is the important one: it tells App Engine what to do with your files. It’s named app.yaml, it sits at the top-level (inside the folder I’ve named 24ways2008), and it needs to include these lines:

application: 24ways2008
version: 1
runtime: python
api_version: 1

handlers:
- url: /
	static_files: assets/index.html
	upload: assets/index.html

- url: /
	static_dir: assets

You need to make sure you change 24ways2008 on the first line to whatever you chose as your application id, but otherwise the content of your app.yaml file should be identical. And with that, you’ve created your first App Engine project. If you want it, you can download a zip file containing my project.

Testing your project

As it stands, your project is ready to be uploaded to App Engine. But we couldn’t call ourselves professionals if we didn’t test it, could we? So, let’s put that downloaded SDK to good use and run the project from your own computer.

One of the files you’ll find App Engine installed is named dev_appserver.py, a Python script used to simulate App Engine on your computer. You’ll find lots of information on how to do this in the documentation on the development web server, but it boils down to running the script like so (the space and the dot at the end are important):

dev_appserver.py .

You’ll need to run this from the command-line: Mac users can run the Terminal application, Linux users can run their favourite shell, and Windows users will need to run it via the Command Prompt (open the Start menu, choose ‘Run…’, type ‘cmd‘, and click ‘OK’). Before you run the script you’ll need to make sure you’re in the project folder — in my case, as I saved it to my desktop I can go there by typing 

cd ~/Desktop/24ways2008

in my Mac’s Terminal app; if you’re using Windows you can type 

cd ""C:\Documents and Settings\username\Desktop\24ways2008""

If that’s successful, you’ll see a few lines of output, the last looking something like this:

INFO     2008-11-22 14:35:00,830 dev_appserver_main.py] Running application 24ways2008 on port 8080: http://localhost:8080

Now you can power up your favourite browser, point it to http://localhost:8080/, and you’ll see the page you saved as index.html. You’ll also find your CSS file at http://localhost:8080/css/core.css. In fact, anything you put inside the assets folder in the project will be accessible from this domain. You’re running our own App Engine web server!

Note that no-one else will be able to see your files: localhost is a special domain that you can only see from your computer — and once you stop the development server (by pressing Control–C) you’ll not be able to see the files in your browser until you start it again.

You might notice a new file has turned up in your project: index.yaml. App Engine creates this file when you run the development server, and it’s for internal App Engine use only. If you delete it there are no ill effects, but it will reappear when you next run the development server. If you’re using version control (e.g. Subversion) there’s no need to keep a copy in your repository.

So you’ve tested your project and you’ve seen it working on your own machine; now all you need to do is upload your project and the world will be able to see your files too.

Uploading your project

If you don’t have a Google account, create one and then sign in to App Engine. Tell Google about your new project by clicking on the ‘Create an Application’ button. Enter your application id, give the application a name, and agree to the terms and conditions. That’s it. All we need do now is upload the files.

Open your Mac OS X Terminal, Windows Command Prompt, or Linux shell window again, move to the project folder, and type (again, the space and the dot at the end are important):

appcfg.py update .

Enter your email address and password when prompted, and let App Engine do it’s thing. It’ll take no more than a few seconds, but in that time App Engine will have done the equivalent of logging in to an FTP server and copying files across. It’s fairly understated, but you now have your own project up and running. You can see mine at http://24ways2008.appspot.com/, and everyone can see yours at http://your-application-id.appspot.com/. Your files are being served up over Google’s content delivery network, at no cost to you!

Benefits of using Google App Engine

The benefits of App Engine as a CDN are obvious: your own server doesn’t suck up the bandwidth, while your visitors will appreciate a faster site. But there are also less obvious benefits.

First, once you’ve set up your site, updating it is an absolute breeze. Each time you update a file (or a batch of files) you need only run appcfg.py to see the changes appear on your site. To paraphrase Joel Spolsky, a good web site must be able to be updated in a single step. Many designers and developers can’t make that claim, but with App Engine, you can.

App Engine also allows multiple people to work on one application. If you want a friend to be able to upload files to your site you can let him do so without giving him usernames and passwords — all he needs is his own Google account. App Engine also gives you a log of all actions taken by collaborators, so you can see who’s made updates, and when.

Another bonus is the simple version control App Engine offers. Do you remember the file named app.yaml you created a while back? The second line looked like this:

version: 1

If you change the version number to 2 (or 3, or 4, etc), App Engine will keep a copy of the last version you uploaded. If anything goes wrong with your latest version, you can tell App Engine to revert back to that last saved version. It’s no proper version control system, but it could get you out of a sticky situation.

One last thing to note: if you’re not happy using your-application-id.appspot.com as your domain, App Engine will quite happily use any domain you own.

The weak points of Google App Engine

In the right circumstances, App Engine can be a real boon. I run my own site using the method I’ve discussed above, and I’m very happy with it. But App Engine does have its disadvantages, most notably those discussed by Aral Balkan in his post ‘Why Google App Engine is broken and what Google must do to fix it‘.

Aral found the biggest problems while using App Engine as a web application platform; I wouldn’t recommend using it as such either (at least for now) but for our purposes as a CDN for static files, it’s much more worthy. Still, App Engine has two shortcomings you should be aware of.

The first is that you can’t host a file larger than one megabyte. If you want to use App Engine to host that 4.3MB download for your latest-and-greatest desktop software, you’re out of luck. The only solution is to stick to smaller files.

The second problem is the quota system. Google’s own documentation says you’re allowed 650,000 requests a day and 10,000 megabytes of bandwidth in and out (20,000 megabytes in total), which should be plenty for most sites. But people have seen sites shut down temporarily for breaching quotas — in some cases after inexplicable jumps in Google’s server CPU usage. Aral, who’s seen it happen to his own sites, seemed genuinely frustrated by this, and if you measure your hits in the hundreds of thousands and don’t want to worry about uptime, App Engine isn’t for you.

That said, for most of us, App Engine offers a fantastic resource: the ability to host files on Google’s own content delivery network, at no charge.

Conclusion

If you’ve come this far, you’ve seen how to create a Google App Engine project and host your own files on Google’s CDN. You’ve seen the great advantages App Engine offers — an excellent content delivery network, the ability to update your site with a single command, multiple authors, simple version control, and the use of your own domain — and you’ve come across some of its weaknesses — most importantly the limit on file sizes and the quota system. All that’s left to do is upload those applications — but not before you’ve finished your Christmas shopping.",2008,Matt Riggott,mattriggott,2008-12-06T00:00:00+00:00,https://24ways.org/2008/using-google-app-engine-as-your-own-cdn/,process
112,User Styling,"During the recent US elections, Twitter decided to add an ‘election bar’ as part of their site design. You could close it if it annoyed you, but the action wasn’t persistent and the bar would always come back like a bad penny. 

The solution to common browsing problems like this is CSS. ‘User styling’ (or the creepy ‘skinning’) is the creation of CSS rules to customise and personalise a particular domain. Aside from hiding adverts and other annoyances, there are many reasons for taking the time and effort to do it:


	Improving personal readability by changing text size and colour
	Personalising the look of a web app like GMail to look less insipid
	Revealing microformats
	Sport! My dreams of site skinning tennis are not yet fully realised, but it’ll be all the rage by next Christmas, believe me.


Hopefully you’re now asking “But how? HOW?!”. The process of creating a site skin is roughly as follows:


	See something you want to change
	Find out what it’s called, and if any rules already apply to it
	Write CSS rule(s) to override and/or enhance it.
	Apply the rules


So let’s get stuck in…

See something

Let’s start small with Multimap.com. Look at that big header – it takes up an awful lot of screen space doesn’t it? 



No matter, we can fix it.

Tools

Now we need to find out where that big assed header is in the DOM, and make overriding CSS rules. The best tool  I’ve found yet is the Mac OS X app, CSS Edit. It utilises a slick ‘override stylesheets’ function and DOM Inspector. Rather than give you all the usual DOM inspection tools, CSS Edit’s is solely concerned with style.  Go into ‘X-Ray’ mode, click an element, and look at the inspector window to see every style rule governing it. Click the selector to be taken to where it lives in the CSS. It really is a user styling dream app.



Having said all that, you can achieve all this with free, cross platform  tools – namely Firefox with the Firebug and Stylish extensions. We’ll be using them for these examples, so make sure you have them installed if you want to follow along.



Using Firebug, we can see that the page is very helpfully marked up, and that whole top area is simply a div with an ID of header. 

Change Something

When you installed Stylish, it added a page and brush icon to your status bar. Click on that, and choose Write Style > for Multimap.com. The other options allow you to only create a style for a particular part of a website or URL, but we want this to apply to the whole of Multimap:



The ‘Add Style’ window then pops up, with the @-moz-document query at the top:

@namespace url(http://www.w3.org/1999/xhtml);
@-moz-document domain(""multimap.com"") {
}

All you need to do is add the CSS to hide the header, in between the curly brackets.

@namespace url(http://www.w3.org/1999/xhtml);
@-moz-document domain(""multimap.com"") {
        #header {display: none;} 
}



A click of the preview button shows us that it’s worked! Now the map appears further up the page. The ethics of hiding adverts is a discussion for another time, but let’s face it, when did you last whoop at the sight of a banner?

Make Something Better

If we’re happy with our modifications, all we need to do is give it a name and save. Whenever you visit Multimap.com, the style will be available. Stylish also allows you to toggle a style on/off via the status bar menu. If you feel you want to share this style with the world, then userstyles.org is the place to do it. It’s a grand repository of customisations that Stylish connects with. Whenever you visit a site, you can see if anyone else has written a style for it, again, via the status bar menu “Find Styles for this Page”. Selecting this with “BBC News” shows that there are plenty of options, ranging from small layout tweaks to redesigns:



What’s more, whenever a style is updated, Stylish will notify you, and offer a one-click process to update it. This does only work in Firefox and Flock, so I’ll cover ways of applying site styles to other browsers later.

Specific Techniques

Important!

In the Multimap example there wasn’t a display specified on that element, but it isn’t always going to be that easy. You may have spent most of your CSS life being a good designer and not resorting to adding !important to give your rule priority. There’s no way to avoid this in user styling – if you’re overriding an existing rule it’s a necessity! Be prepared to be typing !important a lot.

Star Selector

The Universal Selector is a particularly useful way to start a style. For example, if we want to make Flickr use Helvetica before Arial (as they should’ve done!), we can cover all occurrences with just one rule:

* {font-family: ""Helvetica Neue"", Helvetica, sans-serif !important;}

You can also use it to select ‘everything within an element’, by placing it after the element name:

#content * {font-family: ""Helvetica Neue"", Helvetica, sans-serif !important;}

Swapping Images

If you’re changing something a little more complex, such as Google Reader, then at some point you’ll probably want to change an <img>. The technique for replacing an image involves:


	making your replacement image the background of the <img> tag
	adding padding top and left to the size of you image to push the ‘top’ image away
	making the height and width zero.




The old image is then pushed out of the way and hidden from view, allowing the replacement in the background to be revealed.  Targeting the image may require using an attribute selector:

img[src=""/reader/ui/3544433079-tree-view-folder-open.gif""] {
	padding: 16px 0 0 16px;
	width: 0 !important;
	height: 0 !important;

}

Woah boy! What was all that gubbins in the background-image? It was a Data URI, and you can create these easily with Hixie’s online tool. It’s simply the image translated into text so that it can be embedded in the CSS, cutting down on the number of http requests. It’s also a necessity with Mozilla browsers, as they don’t allow user CSS to reference images stored locally. Converting images to URI’s avoids this, as well as making a style easily portable – no images folder to pass around. 

Don’t forget all your other CSS techniques at your disposal: inserting your own content with :before and :after pseudo classes, make elements semi-transparent with opacity and round box corners without hacking . You can have fun, and for once, enjoy the freedom of not worrying about IE!

User styling without Stylish

Instead of using the Stylish extension, you can add rules to the userContent.css file, or use @import in that file to load a separate stylesheet. You can find this is in /Library/Application Support/Camino/chrome/ on OS X, or C/Program Files/Mozilla Firefox/Chrome on Windows. This is only way to apply user styles in Camino, but what about other browsers?

Opera & Omniweb: 

Both allow you to specify a custom CSS file as part of the site’s preferences. Opera also allows custom javascript, using the same syntax as Greasemonkey scripts (more on that below)

Safari

There are a few options here: the PithHelmet and SafariStand haxies both allow custom stylesheets, or alternatively, a Greasemonkey style user script can employed via GreaseKit. The latter is my favoured solution on my Helvetireader theme, as it can allow for more prescriptive domain rules, just like the Mozilla @-moz-document method. User scripts are also the solution supported by the widest range of browsers.

What now?

Hopefully I’ve given you enough information for you to be able start making your own styles. If you want to go straight in and tackle the ‘Holy Grail’, then off with you to GMail – I get more requests to theme that than anything else!

If you’re a site author and want to encourage this sort of tom foolery, a good way is to provide a unique class or ID name with the body tag:

<body id=""journal"" class=""hicksdesign-co-uk"">

This makes it very easy to write rules that only apply to that particular site. If you wanted to use Safari without any of the haxies mentioned above, this method means you can include rules in a general CSS file (chosen via Preferences > Advanced > Stylesheet) without affecting other sites. 

One final revelation on user styling – it’s not just for web sites. You can tweak the UI of Firefox itself with the userChrome.css. You’ll need to use the in-built DOM Inspector instead of Firebug to inspect the window chrome, instead of a page. Great if you want to make small tweaks (changing the size of tab text for example) without creating a full blown theme.",2008,Jon Hicks,jonhicks,2008-12-03T00:00:00+00:00,https://24ways.org/2008/user-styling/,process
116,The IE6 Equation,"It is the destiny of one browser to serve as the nemesis of web developers everywhere. At the birth of the Web Standards movement, that role was played by Netscape Navigator 4; an outdated browser that refused to die. Its tenacious existence hampered the adoption of modern standards. Today that role is played by Internet Explorer 6.

There’s a sensation that I’m sure you’re familiar with. It’s a horrible mixture of dread and nervousness. It’s the feeling you get when—after working on a design for a while in a standards-compliant browser like Firefox, Safari or Opera—you decide that you can no longer put off the inevitable moment when you must check the site in IE6. Fingers are crossed, prayers are muttered, but alas, to no avail. The nemesis browser invariably screws something up.

What do you do next? If the differences in IE6 are minor, you could just leave it be. After all, websites don’t need to look exactly the same in all browsers. But if there are major layout issues and a significant portion of your audience is still using IE6, you’ll probably need to roll up your sleeves and start fixing the problems.

A common approach is to quarantine IE6-specific CSS in a separate stylesheet. This stylesheet can then be referenced from the HTML document using conditional comments like this:

<!--[if lt IE 7]>
<link rel=""stylesheet"" href=""ie6.css"" type=""text/css"" media=""screen"" />
<![endif]-->

That stylesheet will only be served up to Internet Explorer where the version number is less than 7.

You can put anything inside a conditional comment. You could put a script element in there. So as well as serving up browser-specific CSS, it’s possible to serve up browser-specific JavaScript.

A few years back, before Microsoft released Internet Explorer 7, JavaScript genius Dean Edwards wrote a script called IE7. This amazing piece of code uses JavaScript to make Internet Explorer 5 and 6 behave like a standards-compliant browser. Dean used JavaScript to bootstrap IE’s CSS support.

Because the script is specifically targeted at Internet Explorer, there’s no point in serving it up to other browsers. Conditional comments to the rescue:

<!--[if lt IE 7]>
<script src=""http://ie7-js.googlecode.com/svn/version/2.0(beta3)/IE7.js"" type=""text/javascript""></script>
<![endif]-->

Standards-compliant browsers won’t fetch the script. Users of IE6, on the hand, will pay a kind of bad browser tax by having to download the JavaScript file.

So when should you develop an IE6-specific stylesheet and when should you just use Dean’s JavaScript code? This is the question that myself and my co-worker Natalie Downe set out to answer one morning at Clearleft. We realised that in order to answer that question you need to first answer two other questions, how much time does it take to develop for IE6? and how much of your audience is using IE6?

Let’s say that t represents the total development time. Let t6 represent the portion of that time you spend developing for IE6. If your total audience is a, then a6 is the portion of your audience using IE6. With some algebraic help from our mathematically minded co-worker Cennydd Bowles, Natalie and I came up with the following equation to calculate the percentage likelihood that you should be using Dean’s IE7 script:



p = 50 [ log ( at6 / ta6 ) + 1 ]

Try plugging in your own numbers. If you spend a lot of time developing for IE6 and only a small portion of your audience is using that browser, you’ll get a very high number out of the equation; you should probably use the IE7 script. But if you only spend a little time developing for IE6 and a significant portion of you audience are still using that browser, you’ll get a very small value for p; you might as well write an IE6-specific stylesheet.

Of course this equation is somewhat disingenuous. While it’s entirely possible to research the percentage of your audience still using IE6, it’s not so easy to figure out how much of your development time will be spent developing for that one browser. You can’t really know until you’ve already done the development, by which time the equation is irrelevant.

Instead of using the equation, you could try imposing a limit on how long you will spend developing for IE6. Get your site working in standards-compliant browsers first, then give yourself a time limit to get it working in IE6. If you can’t solve all the issues in that time limit, switch over to using Dean’s script. You could even make the time limit directly proportional to the percentage of your audience using IE6. If 20% of your audience is still using IE6 and you’ve just spent five days getting the site working in standards-compliant browsers, give yourself one day to get it working in IE6. But if 50% of your audience is still using IE6, be prepared to spend 2.5 days wrestling with your nemesis.

All of these different methods for dealing with IE6 demonstrate that there’s no one single answer that works for everyone. They also highlight a problem with the current debate around dealing with IE6. There’s no shortage of blog posts, articles and even entire websites discussing when to drop support for IE6. But very few of them take the time to define what they mean by “support.” This isn’t a binary issue. There is no Boolean answer. Instead, there’s a sliding scale of support:


	Block IE6 users from your site.
	Develop with web standards and don’t spend any development time testing in IE6.
	Use the Dean Edwards IE7 script to bootstrap CSS support in IE6.
	Write an IE6 stylesheet to address layout issues.
	Make your site look exactly the same in IE6 as in any other browser.


Each end of that scale is extreme. I don’t think that anybody should be actively blocking any browser but neither do I think that users of an outdated browser should get exactly the same experience as users of a more modern browser. The real meanings of “supporting” or “not supporting” IE6 lie somewhere in-between those extremes.

Just as I think that semantics are important in markup, they are equally important in our discussion of web development. So let’s try to come up with some better terms than using the catch-all verb “support.” If you say in your client contract that you “support” IE6, define exactly what that means. If you find yourself in a discussion about “dropping support” for IE6, take the time to explain what you think that entails.

The web developers at Yahoo! are on the right track with their concept of graded browser support. I’m interested in hearing more ideas of how to frame this discussion. If we can all agree to use clear and precise language, we stand a better chance of defeating our nemesis.",2008,Jeremy Keith,jeremykeith,2008-12-08T00:00:00+00:00,https://24ways.org/2008/the-ie6-equation/,code
117,The First Tool You Reach For,"Microsoft recently announced that Internet Explorer 8 will be released in the first half of 2009. Compared to the standards support of other major browsers, IE8 will not be especially great, but it will finally catch up with the state of the art in one specific area: support for CSS tables. This milestone has the potential to trigger an important change in the way you approach web design.

To show you just how big a difference CSS tables can make, think about how you might code a fluid, three-column layout from scratch. Just to make your life more difficult, give it one fixed-width column, with a background colour that differs from the rest of the page. Ready? Go!

Okay, since you’re the sort of discerning web designer who reads 24ways, I’m going to assume you at least considered doing this without using HTML tables for the layout. If you’re especially hardcore, I imagine you began thinking of CSS floats, negative margins, and faux columns. If you did, colour me impressed!

Now admit it: you probably also gave an inward sigh about the time it would take to figure out the math on the negative margin overlaps, check for dropped floats in Internet Explorer and generally wrestle each of the major browsers into giving you what you want. If after all that you simply gave up and used HTML tables, I can’t say I blame you.

There are plenty of professional web designers out there who still choose to use HTML tables as their main layout tool. Sure, they may know that users with screen readers get confused by inappropriate use of tables, but they have a job to do, and they want tools that will make that job easy, not difficult.

Now let me show you how to do it with CSS tables. First, we have a div element for each of our columns, and we wrap them all in another two divs:

<div class=""container"">
	<div>
		<div id=""menu"">
		⋮
		</div>
		<div id=""content"">
		⋮
		</div>
		<div id=""sidebar"">
		⋮
		</div>
	</div>
</div>

Don’t sweat the “div clutter” in this code. Unlike tables, divs have no semantic meaning, and can therefore be used liberally (within reason) to provide hooks for the styles you want to apply to your page.

Using CSS, we can set the outer div to display as a table with collapsed borders (i.e. adjacent cells share a border) and a fixed layout (i.e. cell widths unaffected by their contents):

.container {
	display: table;
	border-collapse: collapse;
	table-layout: fixed;
}

With another two rules, we set the middle div to display as a table row, and each of the inner divs to display as table cells:

.container > div {
	display: table-row;
}
.container > div > div {
	display: table-cell;
}

Finally, we can set the widths of the cells (and of the table itself) directly:

.container {
	width: 100%;
}
#menu {
	width: 200px;
}
#content {
	width: auto;
}
#sidebar {
	width: 25%;
}

And, just like that, we have a rock solid three-column layout, ready to be styled to your own taste, like in this example:



This example will render perfectly in reasonably up-to-date versions of Firefox, Safari and Opera, as well as the current beta release of Internet Explorer 8.

CSS tables aren’t only useful for multi-column page layout; they can come in handy in most any situation that calls for elements to be displayed side-by-side on the page. Consider this simple login form layout:



The incantation required to achieve this layout using CSS floats may be old hat to you by now, but try to teach it to a beginner, and watch his eyes widen in horror at the hoops you have to jump through (not to mention the assumptions you have to build into your design about the length of the form labels).

Here’s how to do it with CSS tables:

<form action=""/login"" method=""post"">
	<div>
		<div>
			<label for=""username"">Username:</label>
			<span class=""input""><input type=""text"" name=""username"" id=""username""/></span>
		</div>
		<div>
			<label for=""userpass"">Password:</label>
			<span class=""input""><input type=""password"" name=""userpass"" id=""userpass""/></span>
		</div>
		<div class=""submit"">
			<label for=""login""></label>
			<span class=""input""><input type=""submit"" name=""login"" id=""login"" value=""Login""/></span>
		</div>
	</div>
</form>

This time, we’re using a mixture of divs and spans as semantically transparent styling hooks. Let’s look at the CSS code.

First, we set up the outer div to display as a table, the inner divs to display as table rows, and the labels and spans as table cells (with right-aligned text):

form > div {
	display: table;
}
form > div > div {
	display: table-row;
}
form label,
form span {
	display: table-cell;
	text-align: right;
}

We want the first column of the table to be wide enough to accommodate our labels, but no wider. With CSS float techniques, we had to guess at what that width was likely to be, and adjust it whenever we changed our form labels. With CSS tables, we can simply set the width of the first column to something very small (1em), and then use the white-space property to force the column to the required width:

form label {
	white-space: nowrap;
	width: 1em;
}

To polish off the layout, we’ll make our text and password fields occupy the full width of the table cells that contain them:

input[type=text],
input[type=password] {
	width: 100%;
}

The rest is margins, padding and borders to get the desired look. Check out the finished example.

As the first tool you reach for when approaching any layout task, CSS tables make a lot more sense to your average designer than the cryptic incantations called for by CSS floats. When IE8 is released and all major browsers support CSS tables, we can begin to gradually deploy CSS table-based layouts on sites that are more and more mainstream.

In our new book, Everything You Know About CSS Is Wrong!, Rachel Andrew and I explore in much greater detail how CSS tables work as a page layout tool in the real world. CSS tables have their quirks just like floats do, but they don’t tend to affect common layout tasks, and the workarounds tend to be less fiddly too.

104,Sitewide Search On A Shoe String,"One of the questions I got a lot when I was building web sites for smaller businesses was if I could create a search engine for their site. Visitors should be able to search only this site and find things without the maintainer having to put “related articles”  or “featured content” links on every page by hand. 

Back when this was all fields this wasn’t easy as you either had to write your own scraping tool, use ht://dig or a paid service from providers like Yahoo, Altavista or later on Google. In the former case you had to swallow the bitter pill of computing and indexing all your content and storing it in a database for quick access and in the latter it hurt your wallet.

Times have moved on and nowadays you can have the same functionality for free using Yahoo’s “Build your own search service” – BOSS. The cool thing about BOSS is that it allows for a massive amount of hits a day and you can mash up the returned data in any format you want. Another good feature of it is that it comes with JSON-P as an output format which makes it possible to use it without any server-side component!

Starting with a working HTML form

In order to add a search to your site, you start with a simple HTML form which you can use without JavaScript. Most search engines will allow you to filter results by domain. In this case we will search “bbc.co.uk”. If you use Yahoo as your standard search, this could be: 

<form id=""customsearch"" action=""http://search.yahoo.com/search"">
	<div>
		<label for=""p"">Search this site:</label>
		<input type=""text"" name=""p"" id=""term"">
		<input type=""hidden"" name=""vs"" id=""site"" value=""bbc.co.uk"">
		<input type=""submit"" value=""go"">
	</div>
</form>

The Google equivalent is:

<form id=""customsearch"" action=""http://www.google.co.uk/search"">
	<div>
		<label for=""p"">Search this site:</label>
		<input type=""text"" name=""as_q"" id=""term"">
		<input type=""hidden"" name=""as_sitesearch"" id=""site"" value=""bbc.co.uk"">
		<input type=""submit"" value=""go"">
	</div>
</form>

In any case make sure to use the ID term for the search term and site for the site, as this is what we are going to use for the script. To make things easier, also have an ID called customsearch on the form.

To use BOSS, you should get your own developer API for BOSS and replace the one in the demo code. There is click tracking on the search results to see how successful your app is, so you should make it your own.

Adding the BOSS magic

BOSS is a REST API, meaning you can use it in any HTTP request or in a browser by simply adding the right parameters to a URL. Say for example you want to search “bbc.co.uk” for “christmas” all you need to do is open the following URL:

http://boss.yahooapis.com/ysearch/web/v1/christmas?sites=bbc.co.uk&format=xml&appid=YOUR-APPLICATION-ID

Try it out and click it to see the results in XML. We don’t want XML though, which is why we get rid of the format=xml parameter which gives us the same information in JSON:

http://boss.yahooapis.com/ysearch/web/v1/christmas?sites=bbc.co.uk&appid=YOUR-APPLICATION-ID

JSON makes most sense when you can send the output to a function and immediately use it. For this to happen all you need is to add a callback parameter and the JSON will be wrapped in a function call. Say for example we want to call SITESEARCH.found() when the data was retrieved we can do it this way:

http://boss.yahooapis.com/ysearch/web/v1/christmas?sites=bbc.co.uk&callback=SITESEARCH.found&appid=YOUR-APPLICATION-ID

You can use this immediately in a script node if you want to. The following code would display the total amount of search results for the term christmas on bbc.co.uk as an alert:

<script type=""text/javascript"">
	var SITESEARCH = {};
	SITESEARCH.found = function(o){
		alert(o.ysearchresponse.totalhits);
	}
</script>
<script type=""text/javascript"" src=""http://boss.yahooapis.com/ysearch/web/v1/christmas?sites=bbc.co.uk&callback=SITESEARCH.found&appid=Kzv_lcHV34HIybw0GjVkQNnw4AEXeyJ9Rb1gCZSGxSRNrcif_HdMT9qTE1y9LdI-"">
</script>

However, for our example, we need to be a bit more clever with this.

Enhancing the search form




Here’s the script that enhances a search form to show results below it.

SITESEARCH = function(){
	var config = {
		IDs:{
			searchForm:'customsearch',
			term:'term',
			site:'site'
		},
		loading:'Loading results...',
		noresults:'No results found.',
		appID:'YOUR-APP-ID',
		results:20
	};
	var form;
	var out;
	function init(){
		if(config.appID === 'YOUR-APP-ID'){
			alert('Please get a real application ID!');
		} else {
			form = document.getElementById(config.IDs.searchForm);
			if(form){
				form.onsubmit = function(){
					var site = document.getElementById(config.IDs.site).value;
					var term = document.getElementById(config.IDs.term).value;
					if(typeof site === 'string' && typeof term === 'string'){
						if(typeof out !== 'undefined'){
							out.parentNode.removeChild(out);
						}
						out = document.createElement('p');
						out.appendChild(document.createTextNode(config.loading));
						form.appendChild(out);
						var APIurl = 'http://boss.yahooapis.com/ysearch/web/v1/' + 
													term + '?callback=SITESEARCH.found&sites=' + 
													site + '&count=' + config.results + 
													'&appid=' + config.appID;
						var s = document.createElement('script');
						s.setAttribute('src',APIurl);
						s.setAttribute('type','text/javascript');
						document.getElementsByTagName('head')[0].appendChild(s);
						return false;
					}
				};
			}
		}
	};
	function found(o){
		var list = document.createElement('ul');
		var results = o.ysearchresponse.resultset_web;
		if(results){
			var item,link,description;
			for(var i=0,j=results.length;i<j;i++){
				item = document.createElement('li');
				link = document.createElement('a');
				link.setAttribute('href',results[i].clickurl);
				link.innerHTML = results[i].title;
				item.appendChild(link);
				description = document.createElement('p');
				description.innerHTML = results[i]['abstract'];
				item.appendChild(description);
				list.appendChild(item);
			}
		} else {
			list = document.createElement('p');
			list.appendChild(document.createTextNode(config.noresults));
		}
		form.replaceChild(list,out);
		out = list;
	};
	return{
		config:config,
		init:init,
		found:found
	};
}();

Oooohhhh scary code! Let’s go through this one bit at a time:

We start by creating a module called SITESEARCH and give it an configuration object: 

SITESEARCH = function(){
	var config = {
		IDs:{
			searchForm:'customsearch',
			term:'term',
			site:'site'
		},
		loading:'Loading results...',
		appID:'YOUR-APP-ID',
		results:20
	}

Configuration objects are a great idea to make your code easy to change and also to override. In this case you can define different IDs than the one agreed upon earlier, define a message to show when the results are loading, when there aren’t any results, the application ID and the number of results that should be displayed.

Note: you need to replace “YOUR-APP-ID” with the real ID you retrieved from BOSS, otherwise the script will complain! 

var form;
var out;
function init(){
	if(config.appID === 'YOUR-APP-ID'){
		alert('Please get a real application ID!');
	} else {

We define form and out as variables to make sure that all the methods in the module have access to them. We then check if there was a real application ID defined. If there wasn’t, the script complains and that’s that.      

form = document.getElementById(config.IDs.searchForm);
if(form){
	form.onsubmit = function(){
		var site = document.getElementById(config.IDs.site).value;
		var term = document.getElementById(config.IDs.term).value;
		if(typeof site === 'string' && typeof term === 'string'){      

If the application ID was a winner, we check if the form with the provided ID exists and apply an onsubmit event handler. The first thing we get is the values of the site we want to search in and the term that was entered and check that those are strings.

if(typeof out !== 'undefined'){
	out.parentNode.removeChild(out);
}
out = document.createElement('p');
out.appendChild(document.createTextNode(config.loading));
form.appendChild(out);  

If both are strings we check of out is undefined. We will create a loading message and subsequently the list of search results later on and store them in this variable. So if out is defined, it’ll be an old version of a search (as users will re-submit the form over and over again)  and we need to remove that old version.

We then create a paragraph with the loading message and append it to the form.

var APIurl = 'http://boss.yahooapis.com/ysearch/web/v1/' + 
												term + '?callback=SITESEARCH.found&sites=' + 
												site + '&count=' + config.results + 
												'&appid=' + config.appID;
					var s = document.createElement('script');
					s.setAttribute('src',APIurl);
					s.setAttribute('type','text/javascript');
					document.getElementsByTagName('head')[0].appendChild(s);
					return false;
				}
			};
		}
	}
};

Now it is time to call the BOSS API by assembling a correct REST URL, create a script node and apply it to the head of the document. We return false to ensure the form does not get submitted as we want to stay on the page.

Notice that we are using SITESEARCH.found as the callback method, which means that we need to define this one to deal with the data returned by the API.

function found(o){
	var list = document.createElement('ul');
	var results = o.ysearchresponse.resultset_web;
	if(results){
		var item,link,description;

We create a new list and then get the resultset_web array from the data returned from the API. If there aren’t any results returned, this array will not exist which is why we need to check for it. Once we done that we can define three variables to repeatedly store the item title we want to display, the link to point to and the description of the link.

for(var i=0,j=results.length;i<j;i++){
	item = document.createElement('li');
	link = document.createElement('a');
	link.setAttribute('href',results[i].clickurl);
	link.innerHTML = results[i].title;
	item.appendChild(link);
	description = document.createElement('p');
	description.innerHTML = results[i]['abstract'];
	item.appendChild(description);
	list.appendChild(item);
}

We then loop over the results array and assemble a list of results with the titles in links and paragraphs with the abstract of the site. Notice the bracket notation for abstract as abstract is a reserved word in JavaScript2 :).

} else {
		list = document.createElement('p');
		list.appendChild(document.createTextNode(config.noresults));
	}
	form.replaceChild(list,out);
	out = list;
};      

If there aren’t any results, we define a paragraph with the no results message as list. In any case we replace the old out (the loading message) with the list and re-define out as the list.  

return{
		config:config,
		init:init,
		found:found
	};
}();

All that is left to do is return the properties and methods we want to make public. In this case found needs to be public as it is accessed by the API return. We return init to make it accessible and config to allow implementers to override any of the properties.

Using the script


In order to use this script, all you need to do is to add it after the form in the document, override the API key with your own and call init():

<form id=""customsearch"" action=""http://search.yahoo.com/search"">
	<div>
		<label for=""p"">Search this site:</label>
		<input type=""text"" name=""p"" id=""term"">
		<input type=""hidden"" name=""vs"" id=""site"" value=""bbc.co.uk"">
		<input type=""submit"" value=""go"">
	</div>
</form>
<script type=""text/javascript"" src=""boss-site-search.js""></script>
<script type=""text/javascript"">
	SITESEARCH.config.appID = 'copy-the-id-you-know-to-get-where';
	SITESEARCH.init();
</script>

Where to go from here

This is just a very simple example of what you can do with BOSS. You can define languages and regions, retrieve and display images and news and mix the results with other data sources before displaying them. One very cool feature is that by adding a view=keyterms parameter to the URL you can get the keywords of each of the results to drill deeper into the search. An example for this written in PHP is available on the YDN blog. For JavaScript solutions there is a handy wrapper called yboss available to help you go nuts.",2008,Christian Heilmann,chrisheilmann,2008-12-04T00:00:00+00:00,https://24ways.org/2008/sitewide-search-on-a-shoestring/,code
110,Shiny Happy Buttons,"Since Mac OS X burst onto our screens, glossy, glassy, shiny buttons have been almost de rigeur, and have essentially, along with reflections and rounded corners, become a cliché of Web 2.0 “design”. But if you can’t beat ‘em you’d better join ‘em. So, in this little contribution to our advent calendar, we’re going to take a plain old boring HTML button, and 2.0 it up the wazoo. 

But, here’s the catch. We’ll use no images, either in our HTML or our CSS. No sliding doors, no image replacement techniques. Just straight up, CSS, CSS3 and a bit of experimental CSS. And, it will be compatible with pretty much any browser (though with some progressive enhancement for those who keep up with the latest browsers).

The HTML

We’ll start with our HTML.

<button type=""submit"">This is a shiny button</button>

OK, so it’s not shiny yet – but boy will it ever be.

Before styling, that’s going to look like this.

Ironically, depending on the operating system and browser you are using, it may well be a shiny button already, but that’s not the point. We want to make it shiny 2.0. Our mission is to make it look something like this



If you want to follow along at home keep in mind that depending on which browser you are using you may see fewer of the CSS effects we’ve added to create the button. As of writing, only in Safari are all the effects we’ll apply supported.

Taking a look at our finished product, here’s what we’ve done to it:


	We’ve given the button some padding and a width.
	We’ve changed the text color, and given the text a drop shadow.
	We’ve given the button a border.
	We’ve given the button some rounded corners.
	We’ve given the button a drop shadow.
	We’ve given the button a gradient background.


and remember, all without using any images.

Styling the button

So, let’s get to work.

First, we’ll add given the element some padding and a width:

button {
	padding: .5em;
	width: 15em;
}

Next, we’ll add the text color, and the drop shadow:

color: #ffffff;
text-shadow: 1px 1px 1px #000;

A note on text-shadow

If you’ve not seen text-shadows before well, here’s the quick back-story. Text shadow was introduced in CSS2, but only supported in Safari (version 1!) some years later. It was removed from CSS2.1, but returned in CSS3 (in the text module). It’s now supported in Safari, Opera and Firefox (3.1). Internet Explorer has a shadow filter, but the syntax is completely different.

So, how do text-shadows work? The three length values specify respectively a horizontal offset, a vertical offset and a blur (the greater the number the more blurred the shadow will be), and finally a color value for the shadow.

Rounding the corners

Now we’ll add a border, and round the corners of the element:

border: solid thin #882d13;
-webkit-border-radius: .7em;
-moz-border-radius: .7em;
border-radius: .7em;

Here, we’ve used the same property in three slightly different forms. We add the browser specific prefix for Webkit and Mozilla browsers, because right now, both of these browsers only support border radius as an experimental property. We also add the standard property name, for browsers that do support the property fully in the future. 

The benefit of the browser specific prefix is that if a browser only partly supports a given property, we can easily avoid using the property with that browser simply by not adding the browser specific prefix. At present, as you might guess, border-radius is supported in Safari and Firefox, but in each the relevant prefix is required.

border-radius takes a length value, such as pixels. (It can also take two length values, but that’s for another Christmas.) In this case, as with padding, I’ve used ems, which means that as the user scales the size of text up and down, the radius will scale as well. You can test the difference by making the radius have a value of say 5px, and then zooming up and down the text size. 

We’re well and truly on the way now. All we need to do is add a shadow to the button, and then a gradient background.

In CSS3 there’s the box-shadow property, currently only supported in Safari 3. It’s very similar to text-shadow – you specify a horizontal and vertical offset, a blur value and a color.

-webkit-box-shadow: 2px 2px 3px #999; 
box-shadow: 2px 2px 2px #bbb;

Once more, we require the “experimental” -webkit- prefix, as Safari’s support for this property is still considered by its developers to be less than perfect.

Gradient Background

So, all we have left now is to add our shiny gradient effect. Now of course, people have been doing this kind of thing with images for a long time. But if we can avoid them all the better. Smaller pages, faster downloads, and more scalable designs that adapt better to the user’s font size preference. But how can we add a gradient background without an image?

Here we’ll look at the only property that is not as yet part of the CSS standard – Apple’s gradient function for use anywhere you can use images with CSS (in this case backgrounds). In essence, this takes SVG gradients, and makes them available via CSS syntax.

Here’s what the property and its value looks like:

background-image: -webkit-gradient(linear, left top, left bottom, from(#e9ede8), to(#ce401c),color-stop(0.4, #8c1b0b));

Zooming in on the gradient function, it has this basic form:

-webkit-gradient(type, point, point, from(color), to(color),color-stop(where, color));

Which might look complicated, but is less so than at first glance.

The name of the function is gradient (and in this case, because it is an experimental property, we use the -webkit- prefix).

You might not have seen CSS functions before, but there are others, including the attr() function, used with generated content. A function returns a value that can be used as a property value – here we are using it as a background image.

Next we specify the type of the gradient. Here we have a linear gradient, and there are also radial gradients. 

After that, we specify the start and end points of the gradient – in our case the top and bottom of the element, in a vertical line. 

We then specify the start and end colors – and finally one stop color, located at 40% of the way down the element. Together, this creates a gradient that smoothly transitions from the start color in the top, vertically to the stop color, then smoothly transitions to the end color.

There’s one last thing. What color will the background of our button be if the browser doesn’t support gradients? It will be white (or possibly some default color for buttons). Which may make the text difficult or impossible to read. So, we’ll add a background color as well (see why the validator is always warning you when a color but not a background color is specified for an element?).

If we put it all together, here’s what we have:

button {
	width: 15em;
	padding: .5em;
	color: #ffffff;
	text-shadow: 1px 1px 1px #000;
	border: solid thin #882d13;
	-webkit-border-radius: .7em;
	-moz-border-radius: .7em;
	border-radius: .7em;
	-webkit-box-shadow: 2px 2px 3px #999; 
	box-shadow: 2px 2px 2px #bbb;
	background-color: #ce401c;
	background-image: -webkit-gradient(linear, left top, left bottom, from(#e9ede8), to(#ce401c),color-stop(0.4, #8c1b0b));
}

Which looks like this in various browsers:

In Safari (3)



In Firefox 3.1 (3.0 supports border-radius but not text-shadow)



In Opera 10



and of course in Internet Explorer (version 8 shown here)



But it looks different in different browsers

Yes, it does look different in different browsers, but we all know the answer to the question “do web sites need to look the same in every browser?“.

Even if you really think sites should look the same in every browser, hopefully this little tutorial has whet your appetite for what CSS3 and experimental CSS that’s already supported in widely used browsers (and we haven’t even touched on animations and similar effects!).

I hope you’ve enjoyed out little CSSMas present, and look forward to seeing your shiny buttons everywhere on the web.

Oh, and there’s just a bit of homework – your job is to use the :hover selector, and make a gradient in the hover state.",2008,John Allsopp,johnallsopp,2008-12-18T00:00:00+00:00,https://24ways.org/2008/shiny-happy-buttons/,code
119,Rocking Restrictions,"I love my job. I live my job. For every project I do, I try to make it look special. I’ll be honest: I have a fetish for comments like “I never saw anything like that!” or, “I wish I thought of that!”. I know, I have an ego-problem. (Eleven I’s already)

But sometimes, you run out of inspiration. Happens to everybody, and everybody hates it. “I’m the worst designer in the world.” “Everything I designed before this was just pure luck!” No it wasn’t.

Countless articles about finding inspiration have already been written. Great, but they’re not the magic potion you’d expect them to be when you need it. Here’s a list of small tips that can have immediate effect when applying them/using them. Main theme: Liberate yourself from the designers’ block by restricting yourself.

Do’s

Grids

If you aren’t already using grids, you’re doing something wrong. Not only are they a great help for aligning your design, they also restrict you to certain widths and heights. (For more information about grids, I suggest you read Mark Boulton’s series on designing grid systems. Oh, he’s also publishing a book I think.)

So what’s the link between grids and restrictions? Instead of having the option to style a piece of layout with a width of 1 to 960 pixels, you have to choose from values like 60 pixels, 140, 220, 300, …

Start small

Having a hard time finding a style for the layout, why don’t you start with one small object? No, not that small object, I meant a piece of a form, or a link, or try styling your headers (h1 – h6).

Let’s take a submit button of a form: it’s small, but needs much attention. People will click it. People will hover it. Maybe sometimes it’s disabled? Also: a button needs to look like a button, so typically it requires more styling then a regular link. Once you’ve got the button, move on, following the button’s style.

Color palettes

There are lots of resources on the web for finding inspiration for color palettes. Some of the most famous are COLOURlovers, wear palettes and Adobe’s Kuler. Browse through them (or create your own from a picture), pick a color palette you like and which works with the subject you’re handling, and stick with it. 4-5 colors, maybe with some tonal variations, but that’s it.

Fonts

There aren’t many fonts available for the web (Richard Rutter has a great article on this subject), but you’d be surprised how long they go. A simple text-transform: uppercase; or font-style: italic; can change a dull looking font into something entirely fresh.

Play around with the fonts you want to use and the variations you’ll be using, and make a list. Pick five combinations of fonts and their variations, and stick with them throughout the layout.

Single-task

Most of us use multiple monitors. They’re great to increase productivity, but make it harder to focus on a single task. Here’s what you do: try using only your smallest monitor. Maybe it’s the one from your laptop, maybe it’s an old 1024×768 you found in the attic. Having Photoshop (or Fireworks or…) taking over your entire workspace blocks out all the other distractions on your screen, and works quite liberating.

Mute everything…

…but not entirely. I noticed I was way more focused when I set NetNewsWire to refresh it’s feeds only once every two hours. After two hours, I need a break anyway. Turning off Twitterrific was a mistake, as it’s my window to the world, and it’s the place where the people I like to call colleagues live. You can’t exactly ask them to bring you a cup of coffee when they go to the vending machine, but they do keep you fresh, and it stops you from going human-shy. Instead I changed the settings to not play a notification sound when new Tweets arrive so it doesn’t disturb me when I’m zoning.

Don’ts

CSS galleries

Don’t start browsing all kinds of CSS galleries. Either you’ll feel bad, or you just start using elements in a way you can’t call “inspired” anymore. Instead gather your own collection of inspiration. Example: I use LittleSnapper in which I dump everything I find inspiring. This goes from a smart layout idea, to a failed picture someone posted on Flickr. Everything is inspiring.

Panicking

Don’t panic. It’s the worst thing you could do. Instead, get away from the computer, and go to bed early. A good night of sleep combined with a hot/cold shower can give you a totally new perspective on a design. Got a deadline by tomorrow? Well, you should’ve started earlier. Got a good excuse to start on this design this late? Tell your client it was either that or a bad design.

120-hour work-week

Don’t work all day long, including evenings and early mornings. Write off that first hour, you don’t really think you’ll get anything productive done before 9AM?! I don’t even think you should work on one and the same design all day long. If you’re stuck, try working in blocks of 1 or 2 hours on a certain design. Mixing projects isn’t for everyone, but it might just do the trick for you.

Summary


	Use grids, not only for layout purposes.
	Pick a specific element to start with.
	Use a colour palette.
	Limit the amount of fonts and variations you’ll use.
	Search for the smallest monitor around, and restrict yourself to that one.
	Reduce the amount of noise.
	Don’t start looking on the internet for inspiration. Build your own little inspirarchive.
	Work in blocks.",2008,Tim Van Damme,timvandamme,2008-12-14T00:00:00+00:00,https://24ways.org/2008/rocking-restrictions/,process
103,Recession Tips For Web Designers,"For web designers, there are four keys to surviving bad economic times: do good work, charge a fair price, lower your overhead, and be sure you are communicating with your client. As a reader of 24 ways, you already do good work, so let’s focus on the rest.

I know something about surviving bad times, having started my agency, Happy Cog, at the dawn of the dot-com bust. Of course, the recession we’re in now may end up making the dot-com bust look like the years of bling and gravy. But the bust was rough enough at the time. 

Bad times are hard on overweight companies and over-leveraged start-ups, but can be kind to freelancers and small agencies. Clients who once had money to burn and big agencies to help them burn it suddenly consider the quality of work more important than the marquee value of the business card. Fancy offices and ten people at every meeting are out. A close relationship with an individual or small team that listens is in.

Thin is in

If you were good in client meetings when you were an employee, print business cards and pick a name for your new agency. Once some cash rolls in, see an accountant. 

If the one-person entrepreneur model isn’t you, it’s no problem. Form a virtual agency with colleagues who complement your creative, technical, and business skills. Athletics is a Brooklyn-based multi-disciplinary “art and design collective.” Talk about low overhead: they don’t have a president, a payroll, or a pension plan. But that hasn’t stopped clients like adidas, Nike, MTV, HBO, Disney, DKNY, and Sundance Channel from knocking on their (virtual) doors.

Running a traditional business is like securing a political position in Chicago: it costs a fortune. That’s why bad times crush so many companies. But you are a creature of the internets. You don’t need an office to do great work. I ran Happy Cog out of my apartment for far longer than anyone realized. My clients, when they learned my secret, didn’t care. 

Keep it lean: if you can budget your incoming freelance money, you don’t have to pay yourself a traditional salary. Removing the overhead associated with payroll means more of the budget stays in your pocket, enabling you to price your projects competitively, while still within industry norms. (Underpricing is uncool, and clients who knowingly choose below-market-rate vendors tend not to treat those vendors with respect.)

Getting gigs

Web design is a people business. If things are slow, email former clients. If you just lost your job, email former agency clients with whom you worked closely to inform them of your freelance business and find out how they’re doing. Best practice: focus the email on wishing them a happy holiday and asking how they’re doing. Let your email signature file tell them you’re now the president of Your Name Design. Leading with the fact that you just lost your job may earn sympathy (or commiseration: the client may have lost her job, too) but it’s not exactly a sure-fire project getter.

The qualities that help you land a web design project are the same in good times or bad. Have a story to tell about the kind of services you offer, and the business benefits they provide. (If you design with web standards, you already have one great story line. What are the others?) 

Don’t be shy about sharing your story, but don’t make it the focus of the meeting. The client is the focus. Before you meet her, learn as much as you can about her users, her business, and her competitors. At the very least, read her site’s About pages, and spend some quality time with Google. 

Most importantly, go to the meeting knowing how much you don’t know. Arrive curious, and armed with questions. Maintain eye contact and keep your ears open. If a point you raise causes two people to nod at each other, follow up on that point, don’t just keep grinding through your Keynote presentation. 

If you pay attention and think on your feet, it tells the potential client that they can expect you to listen and be flexible. (Clients are like unhappy spouses: they’re dying for someone to finally listen.) If you stick to a prepared presentation, it might send the message that you are inflexible or nervous or both. “Nervous” is an especially bad signal to send. It indicates that you are either dishonest or inexperienced. Neither quality invites a client to sign on. Web design is a people business for the client, too: they should feel that their interactions with you will be pleasant and illuminating. And that you’ll listen. Did I mention that?

Give it time

Securing clients takes longer and requires more effort in a recession. If two emails used to land you a gig, it will now take four, plus an in-person meeting, plus a couple of follow-up calls. This level of salesmanship is painful to geeks and designers, who would rather spend four hours kerning type or debugging a style sheet than five minutes talking business on the telephone. I know. I’m the same way. But we must overcome our natural shyness and inwardness if we intend not to fish our next meal out of a neighbor’s garbage can. 

As a bonus, once the recession ends, your hard-won account management skills will help you take your business to the next level. By the time jobs are plentiful again, you may not want to work for anyone but yourself. You’ll be a captain of our industry. And talented people will be emailing to ask you for a job.",2008,Jeffrey Zeldman,jeffreyzeldman,2008-12-24T00:00:00+00:00,https://24ways.org/2008/recession-tips-for-web-designers/,business
100,Moo'y Christmas,"A note from the editors:  Moo has changed their API since this article was written.
                
                
                      
                As the web matures, it is less and less just about the virtual world. It is becoming entangled with our world and it is harder to tell what is virtual and what is real. There are several companies who are blurring this line and make the virtual just an extension of the physical. Moo is one such company. 

Moo offers simple print on demand services. You can print business cards, moo mini cards, stickers, postcards and more. They give you the ability to upload your images, customize them, then have them sent to your door. Many companies allow this sort of digital to physical interaction, but Moo has taken it one step further and has built an API. 

Printable stocking stuffers 

The Moo API consists of a simple XML file that is sent to their servers. It describes all the information needed to dynamically assemble and print your object. This is very helpful, not just for when you want to print your own stickers, but when you want to offer them to your customers, friends, organization or community with no hassle. Moo handles the check-out and shipping, all you need to do is what you do best, create! 

Now using an API sounds complicated, but it is actually very easy. I am going to walk you through the options so you can easily be printing in no time. 

Before you can begin sending data to the Moo API, you need to register and get an API key. This is important, because it allows Moo to track usage and to credit you. To register, visit http://www.moo.com/api/ and click “Request an API key”. 

In the following examples, I will use {YOUR API KEY HERE} as a place holder, replace that with your API key and everything will work fine. 

First thing you need to do is to create an XML file to describe the check-out basket. Open any text-editor and start with some XML basics. Don’t worry, this is pretty simple and Moo gives you a few tools to check your XML for errors before you order. 

<?xml version=""1.0"" encoding=""UTF-8""?> 
<moo xsi:noNamespaceSchemaLocation=""http://www.moo.com/xsd/api_0.7.xsd"" xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance""> 
	 <request>
		 <version>0.7</version>
		 <api_key>{YOUR API KEY HERE}</api_key>
		 <call>build</call>
		 <return_to>http://www.example.com/return.html</return_to>
		 <fail_to>http://www.example.com/fail.html</fail_to>
	 </request>
	 <payload>
	 ...
	 </payload>
</moo>

Much like HTML’s <head> and <body>, Moo has created <request> and <payload> elements all wrapped in a <moo> element. 

The <request> element contains a few pieces of information that is the same across all the API calls. The <version> element describes which version of the API is being used. This is more important for Moo than for you, so just stick with “0.7” for now. 

The <api_key> allows Moo to track sales, referrers and credit your account. 

The <call> element can only take “build” so that is pretty straight forward. The <return_to> and <fail_to> elements are URLs. These are optional and are the URLs the customer is redirected to if there is an error, or when the check out process is complete. This allows for some basic branding and a custom “thank you” page which is under your control. That’s it for the <request> element, pretty easy so far! 

Next up is the <payload> element. What goes inside here describes what is to be printed. There are two possible elements, we can put <chooser> or we can put <products> directly inside <payload>. They work in a similar ways, but they drop the customer into different parts of the Moo checkout process. 

If you specify <products> then you send the customer straight to the Moo payment process. If you specify <chooser> then you send the customer one-step earlier where they are allowed to pick and choose some images, remove the ones they don’t like, adjust the crop, etc. The example here will use <chooser> but with a little bit of homework you can easily adjust to <products> if you desire. 

... 
<chooser> 
	 <product_type>sticker</product_type> 
	 <images> 
		 <url>http://example.com/images/christmas1.jpg</url> 
	 </images> 
</chooser> 
...

Inside the <chooser> element, we can see there are two basic piece of information. The type of product we want to print, and the images that are to be printed. The <product_type> element can take one of five options and is required! The possibilities are: minicard, notecard, sticker, postcard or greetingcard. We’ll now look at two of these more closely. 

Moo Stickers 

In the Moo sticker books you get 90 small squarish stickers in a small little booklet. 



The simplest XML you could send would be something like the following payload:

...
<payload>
	<chooser>
		<product_type>sticker</product_type>
		<images>
			<url>http://example.com/image1.jpg</url>
		</images>
		<images>
			<url>http://example.com/image2.jpg</url>
		</images>
		<images>
			<url>http://example.com/image3.jpg</url>
		</images>
	</chooser>
</payload>
...

This creates a sticker book with only 3 unique images, but 30 copies of each image. The Sticker books always print 90 stickers in multiples of the images you uploaded. That example only has 3 <images> elements, but you can easily duplicate the XML and send up to 90. The <url> should be the full path to your image and the image needs to be a minimum of 300 pixels by 300 pixels.

You can add more XML to describe cropping, but the simplest option is to either, let your customers choose or to pre-crop all your images square so there are no issues.

The full XML you would post to the Moo API to print sticker books would look like this:

<?xml version=""1.0"" encoding=""UTF-8""?> 
<moo xsi:noNamespaceSchemaLocation=""http://www.moo.com/xsd/api_0.7.xsd"" xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance""> 
	<request>
		<version>0.7</version>
		<api_key>{YOUR API KEY HERE}</api_key>
		<call>build</call>
		<return_to>http://www.example.com/return.html</return_to>
		<fail_to>http://www.example.com/fail.html</fail_to>
	</request>
	<payload>
		<chooser>
			<product_type>sticker</product_type>
			<images>
				<url>http://example.com/image1.jpg</url>
			</images>
			<images>
				<url>http://example.com/image2.jpg</url>
			</images>
			<images>
				<url>http://example.com/image3.jpg</url>
			</images>
		</chooser>
	</payload> 
</moo>

Mini-cards 

The mini-cards are the small cute business cards in 14×35 dimensions and come in packs of 100. 



Since the mini-cards are print on demand, this allows you to have 100 unique images on the back of the cards.

Just like the stickers example, we need the same XML setup. The <moo> element and <request> elements will be the same as before. The part you will focus on is the <payload> section. 

Since you are sending along specific information, we can’t use the <chooser> option any more. Switch this to <products> which has a child of <product>, which in turn has a <product_type> and <designs>. This might seem like a lot of work, but once you have it set up you won’t need to change it.

...
<payload>
	<products>
		<product>
			<product_type>minicard</product_type>
			<designs>
				...
			</designs>
		</product>
	</products>
</payload>
...

So now that we have the basic framework, we can talk about the information specific to minicards. Inside the <designs> element, you will have one <design> for each card. Much like before, this contains a way to describe the image. Note that this time the element is called <image>, not images plural. 

Inside the <image> element you have a <url> which points to where the image lives and a <type>. The <type> should just be set to ‘variable’. You can pass crop information here instead, but we’re going to keep it simple for this tutorial. If you are interested in how that works, you should refer to the official API documentation.

...
<design>
	<image>
		<url>http://example.com/image1.jpg</url>
		<type>variable</type>
	</image>
</design>
...

So far, we have managed to build a pack of 100 Moo mini-cards with the same image on the front. If you wanted 100 different images, you just need to replicate this snippit, 99 more times.

That describes the front design, but the flip-side of your mini-cards can contain 6 lines of text, which is customizable in a variety of colors, fonts and styles.

The API allows you to create different text on the back of each mini-card, something the web interface doesn’t implement. To describe the text on the mini-card we need to add a <text_collection> element inside the <design> element. If you skip this element, the back of your mini-card will just be blank, but that’s not very festive!

Inside the <text_collection> element, we need to describe the type of text we want to format, so we add a <minicard> element, which in turn contains all the lines of text. Each of Moo’s printed products take different numbers of lines of text, so if you are not planning on making mini-cards, be sure to consult the documentation.

For mini-cards, we can have 6 distinct lines, each with their own style and layout. Each line is represented by an element <text_line> which has several optional children. The <id> tells which line of the 6 to print the text one. The <string> is the text you want to print and it must be shorter than 38 characters. The <bold> element is false by default, but if you want your text bolded, then add this and set it to true. 

The <align> element is also optional. By default it is set to align left. You can also set this to right or center if you desirer. The <font> element takes one of 3 types, modern, traditional or typewriter. The default is modern. Finally, you can set the <colour>, yes that’s color with a ‘u’, Moo is a British company, so they get to make the rules. When you start a print on demand company, you can spell it however you want. The <colour> element takes a 6 character hex value with a leading #.

<design>
	...
	<text_collection>
		<minicard>
			<text_line>
				<id>(1-6)</id>
				<string>String, I must be less than 38 chars!</string>
				<bold>true</bold>
				<align>left</align>
				<font>modern</font>
				<colour>#ff0000</colour> 
			</text_line>
		</minicard>
	</text_collection>
</design>

If you combine all of this into a mini-card request you’d get this example:

<?xml version=""1.0"" encoding=""UTF-8""?> 
<moo xsi:noNamespaceSchemaLocation=""http://www.moo.com/xsd/api_0.7.xsd"" xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance""> 
	<request>
		<version>0.7</version>
		<api_key>{YOUR API KEY HERE}</api_key>
		<call>build</call>
		<return_to>http://www.example.com/return.html</return_to>
		<fail_to>http://www.example.com/fail.html</fail_to>
	</request>
	<payload>
		<products>
			<product>
				<product_type>minicard</product_type>
				<designs>

								</text_line>
							</minicard>
						</text_collection>
					</design>
				</designs>
			</product>
		</products>
	</payload> 
</moo>

Now you know how to construct the XML that describes what to print. Next, you need to know how to send it to Moo to make it happen!

Posting to the API

So your XML is file ready to go. First thing we need to do is check it to make sure it’s valid. Moo has created a simple validator where you paste in your XML, and it alerts you to problems.

When you have a fully valid XML file, you’ll want to send that to the Moo API. There are a few ways to do this, but the simplest is with an HTML form. 

This is the sample code for an HTML form with a big “Buy My Stickers” button. Once you know that it is working, you can use all your existing HTML knowledge to style it up any way you like.

<form method=""POST"" action=""http://www.moo.com/api/api.php"">
	<input type=""hidden"" name=""xml"" value=""<?xml version=""1.0"" encoding=""UTF-8""?> <moo xsi:noNamespaceSchemaLocation=""http://www.moo.com/xsd/api_0.7.xsd"" xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance""> <request>....</request> <payload>...</payload> </moo> ""> 
	<input type=""submit"" name=""submit"" value=""Buy My Stickers""/>
</form>

This is just a basic <form> element that submits to the Moo API, http://www.moo.com/api/api.php, when someone clicks the button. There is a hidden input called “xml” which contains the value the XML file we created previously.

For those of you who need to “view source” to fully understand what’s happening can see a working version and peek under the hood.

Using the API has advantages over uploading the images directly yourself. The images and text that you send via the API can be dynamic. Some companies, like Dopplr, have taken user profiles and dynamic data that changes every minute to generate customer stickers of places that you’ve travelled to or mini-cards with a world map of all the cities you have visited. Every single customer has different travel plans and therefore different sets of stickers and mini-card maps. The API allows for the utmost current information to be printed, on demand, in real-time.

Go forth and Moo’ltiply

See, making an API call wasn’t that hard was it? You are now 90% of the way to creating anything with the Moo API. With a bit of reading, you can learn that extra 10% and print any Moo product. Be on the lookout in 2009 for the official release of the 1.0 API with improvements and some extras that were not available when this article was written.

97,Making Modular Layout Systems,"For all of the advantages the web has with distribution of content, I’ve always lamented the handiness of the WYSIWYG design tools from the print publishing world. When I set out to redesign my personal website, I wanted to have some of the same abilities that those tools have, laying out pages how I saw fit, and that meant a flexible system for dealing with imagery. 

Building on some of the CSS that Eric Meyer employed a few years back on the A List Apart design, I created a set of classes to use together to achieve the variety I was after. Employing multiple classes isn’t a new technique, but most examples aren’t coming at this from strictly editorial and visual perspectives; I wanted to have options to vary my layouts depending on content.

If you want to skip ahead, you can view the example first.

Laying the Foundation

We need to be able to map out our page so that we have predictable canvas, and then create a system of image sizes that work with it. For the sake of this article, let’s use a simple uniform 7-column grid, consisting of seven 100px-wide columns and 10px of space between each column, though you can use any measurements you want as long as they remain constant.


All of our images will have a width that references the grid column widths (in our example, 100px, 210px, 320px, 430px, 540px, 650px, or 760px), but the height can be as large as needed.


Once we know our images will all have one of those widths, we can setup our CSS to deal with the variations in layout. In the most basic form, we’re going to be dealing with three classes: one each that represent an identifier, a size, and a placement for our elements.


This is really a process of abstracting the important qualities of what you would do with a given image in a layout into separate classes, allowing you to quickly customize their appearance by combining the appropriate classes. Rather than trying to serve up a one-size-fits-all approach to styling, we give each class only one or two attributes and rely on the combination of classes to get us there.


Identifier

This specifies what kind of element we have: usually either an image (pic) or some piece of text (caption).


Size

Since we know how our grid is constructed and the potential widths of our images, we can knock out a space equal to the width of any number of columns. In our example, that value can be one, two, three, four, five, six, or seven.

Placement

This tells the element where to go. In our example we can use a class of left or right, which sets the appropriate floating rule.


Additions

I created a few additions that be tacked on after the “placement” in the class stack: solo, for a bit more space beneath images without captions, frame for images that need a border, and inset for an element that appears inside of a block of text. Outset images are my default, but you could easily switch the default concept to use inset images and create a class of outset to pull them out of the content columns.


The CSS

/* I D E N T I F I E R */
.pic p, .caption {
    font-size: 11px;
    line-height: 16px;
    font-family: Verdana, Arial, sans-serif;
    color: #666;
    margin: 4px 0 10px;
}
/* P L A C E M E N T */
.left {float: left; margin-right: 20px;}
.right {float: right; margin-left: 20px;}
.right.inset {margin: 0 120px 0 20px;} /* img floated right within text */
.left.inset {margin-left: 230px;} /* img floated left within text */
/* S I Z E */
.one {width: 100px;}
.two {width: 210px;}
.three {width: 320px;}
.four {width: 430px;}
.five {width: 540px;}
.six {width: 650px;}
.seven {width: 760px;}
.eight {width: 870px;}
/* A D D I T I O N S */
.frame {border: 1px solid #999;}
.solo img {margin-bottom: 20px;}

In Use

You can already see how powerful this approach can be. If you want an image and a caption on the left to stretch over half of the page, you would use:

<div class=""pic four left"">
	<img src=""image.jpg"" />
	<p>Caption goes here.</p>
</div>

Or, for that same image with a border and no caption:

<img src=""image.jpg"" class=""pic four left frame solo""/>

You just tack on the classes that contain the qualities you need. And because we’ve kept each class so simple, we can apply these same stylings to other elements too:

<p class=""caption two left"">Caption goes here.</p>

Caveats

Obviously there are some potential semantic hang-ups with these methods. While classes like pic and caption stem the tide a bit, others like left and right are tougher to justify. This is something that you have to decide for yourself; I’m fine with the occasional four or left class because I think there’s a good tradeoff. Just as a fully semantic solution to this problem would likely be imperfect, this solution is imperfect from the other side of the semantic fence. Additionally, IE6 doesn’t understand the chain of classes within a CSS selector (like .right.inset). If you need to support IE6, you may have to write a few more CSS rules to accommodate any discrepancies.

Opportunities

This is clearly a simple example, but starting with a modular foundation like this leaves the door open for opportunity. We’ve created a highly flexible and human-readable system for layout manipulation. Obviously, this is something that would need to be tailored to the spacing and sizes of your site, but the systematic approach is very powerful, especially for editorial websites whose articles might have lots of images of varying sizes. It may not get us fully to the flexibility of WYSIWYG print layouts, but methods like this point us in a direction of designs that can adapt to the needs of the content.

114,How To Create Rockband'ism,"There are mysteries happening in the world of business these days. We want something else by now. The business of business has to become more than business. We want to be able to identify ourselves with the brands we purchase and we want them to do good things. We want to feel cool because we buy stuff, and we don’t just want a shopping experience – we want an engagement with a company we can relate to.

Let me get back to “feeling cool” – if we want to feel cool, we might get the companies we buy from to support that. That’s why I am on a mission to make companies into rockbands.

Now when I say rockbands – I don’t mean the puke-y, drunky, nasty stuff that some people would highlight is also a part of rockbands. Therefore I have created my own word “rockband’ism”. This word is the definition of a childhood dream version of being in a rockband – the feeling of being more respected and loved and cool, than a cockroach or a suit on the floor of a company.

Rockband’ism

Rockband’ism is what we aspire to, to feel cool and happy.

So basically what I am arguing is that companies should look upon themselves as rockbands. Because the world has changed, so business needs to change as well.

I have listed a couple of things you could do today to become a rockband, as a person or as a company.

1 – Give your support to companies that make a difference to their surroundings – if you are buying electronics look up what the electronic producers are doing of good in the world (check out the Greenpeace Guide to Greener Electronics).

2 – Implement good karma in your everyday life (and do well by doing good). What you give out you get back at some point in some shape – this can also be implemented for business.

3 – WWRD? – “what would a rockband do”? or if you are into Kenny Rogers – what would he do in any given situation? This will also show yourself where your business or personal integrity lies because you actually act as a person or a rockband you admire.

4 – Start leading instead of managing – If we can measure stuff why should we manage it? Leadership is key here instead of management. When you lead you tell people how to reach the stars, when you manage you keep them on the ground.

5 – Respect and confide in, that people are the best at what they do. If they aren’t, they won’t be around for long. If they are and you keep on buggin’ them, they won’t be around for long either.

6 – Don’t be arrogant – Because audiences can’t stand it – talk to people as a person not as a company.

7 – Focus on your return on involvement – know that you get a return on, what you involve yourself in. No matter if it’s bingo, communities, talks, ornithology or un-conferences.

8 – Find out where you can make a difference and do it. Don’t leave it up to everybody else to save the world.

9 – Find out what you can do to become an authentic, trustworthy and remarkable company. Maybe you could even think about this a lot and make these thoughts into an actionplan.

10 – Last but not least – if you’re not happy – do something else, become another type of rockband, maybe a soloist of a sort, or an orchestra.

No more business as usual

This really isn’t time for more business as usual, our environment (digital, natural, work or any other kind of environment) is changing. You are going to have to change too.

This article actually sprang from a talk I did at the Shift08 conference in Lisbon in October. In addition to this article for 24 ways I have turned the talk into an eBook that you can get on Toothless Tiger Press for free.

118,Ghosts On The Internet,"By rights the internet should be full of poltergeists, poor rootless things looking for their real homes. Many events on the internet are not properly associated with their correct timeframe. I don’t mean a server set to the wrong time, though that happens too. Much of the content published on the internet is separated from any proper reference to its publication time. What does publication even mean? Let me tell you a story…


	“It is 2019 and this is Kathy Clees reporting on the story of the moment, the shock purchase of Microsoft by Apple Inc. A Internet Explorer security scare story from 2008 was responsible, yes from 11 years ago, accidently promoted by an analyst, who neglected to check the date of their sources.”


If you think this is fanciful nonsense, then cast your mind back to September 2008, this story in Wired or The Times (UK) about a huge United Airlines stock tumble. A Florida newspaper had a automated popular story section. A random reader looking at a story about United’s 2002 Bankruptcy proceedings caused this story to get picked up by Google’s later visit to the South Florida Sun Sentinel’s news home page. 

The story was undated, Google’s news engine apparently gave it a 2008 date, an analyst picked it up and pushed it to Bloomberg and within minutes the United stock was tumbling. Their stock price dropped from $12 to $3, then recovered to $11 over the day. An eight percent fall in share price over a mis-configured date

Completing this out of order Christmas Carol, lets look at what is current practice and how dates are managed, we might even get to clank some chains. Publication date used to be inseparable from publication, the two things where stamped on the same piece of paper. How can we determine when things have been published, now?

Determining publication dates

Time as defined by http://www.w3.org/TR/NOTE-datetime extends ISO 8601, mandating the use of a year value. This is pretty well defined, we can even get very accurate timings down to milliseconds, Ruby and other languages can even handle Calendar reformation. So accuracy is not the issue.

One problem is that there are many dates which could be interpreted as the publication date. Publication can mean any of date written or created; date placed on server; last modified date; or the current date from the web server. Created and modified have parallels with file systems, but the large number of database driven websites means that this no longer holds much meaning, as there are no longer any files. 

Checking web server HEAD may also not correspond, it might give the creation time for the HTML file you are viewing or it might give the last modified time for a file from disk. It is too unreliable and lacking in context to be of real value. So if the web server will not help, then how can we get the right timeframe for our content? 

We are left with URLs and the actual page content.



Looking at Flickr, this picture (by Douglas County History Research Center) has four date values which can be associated with it. It was taken around 1900, scanned in 1992 and placed on Flickr on July 29th, 2008 and replaced later that day. Which dates should be represented here? 

This is hard question to answer, but currently the date of upload to Flickr is the best represented in terms of the date URL, /photos/douglascountyhistory/archives/date-posted/2008/07/29/, plus some Dublin Core RDF for the year. Flickr uses 2008 as the value for this image. Not accurate, but a reasonable compromise for the millions of other images on their site.

Flickr represents location much better than it represents time. For the most part this is fine, but once you go back in time to the 1800s then the maps of the world start to change a lot and you need to reference both time and place.

The Google timeline search offers another interesting window on the world, showing results organised by decade for any search term. Being able to jump to a specific occurrence of a term makes it easier to get primary results rather than later reporting. 

The 1918 “Spanish flu” results jump out in this timeline. 



Any major news event will have multiple analysis articles after the event, finding the original reporting of hurricane Katrina is harder now. Many publishers are putting older content online, e.g. Harpers or Nature or The Times, often these use good date based URLs, sometimes they are unhelpful database references. If this content is available for free, then how much better would it be to provide good metadata on date of publication.

Date based URLs

A quick word on date based URLs, they can be brilliant at capturing first published date. However they can be hard to interpret. Is /03/04 a date in March or April, what about 08/03/04? Obviously 2008/03/04 is easier to understand, it is probably March 4th. Including a proper timestamp in the page content avoid this kind of guesswork. 

Many sites represent the date as a plain text string; a few hook an HTML class of date around it, a very few provide an actual timestamp. Associating the date with the individual content makes it harder to get the date wrong.

Movable Type and TypePad are a notable exceptions, they will embed Dublin Core RDF to represent each posting e.g. dc:date=""2008-12-18T02:57:28-08:00"". WordPress doesn’t support date markup out of the box, though there is a patch and a howto for hAtom available.

In terms of newspapers, the BBC use <meta name=""OriginalPublicationDate"" content=""2008/12/18 18:52:05"" /> along with opaque URLs such as http://news.bbc.co.uk/1/hi/technology/7787335.stm. 

The Guardian use nice clear URLs http://www.guardian.co.uk/business/2008/dec/18/car-industry-recession but have no marked up date on the page. 

The New York Times are similar to the Guardian with nice URLs, http://www.nytimes.com/2008/12/19/business/19markets.html, but again no timestamps. All of these papers have all the data available, but it is not marked up in a useful manner.

Syndication formats

Syndication formats are better at supporting dates, RSS uses RFC 822 for dates, just like email so dates such as Wed, 17 Dec 2008 12:52:40 GMT are valid, with all the white space issues that entails. 

The Atom syndication format uses the much clearer http://tools.ietf.org/html/rfc3339 with timestamps of the form 1996-12-19T16:39:57-08:00. Both syndication formats encourage the use of last modified. This is understandable, but a pity as published date is a very useful value. The Atom syndication format supports “published” and mandates “updated” as timestamps, see the Atom RFC 4287 for more detail.

Marking up dates

However the aim of this short article is to encourage you to use microformats or RDF to encode dates. A good example of this is Twitter, they use hAtom for each individual entry, http://twitter.com/zzgavin/status/1065835819 contains the following markup, which represents a human and a machine readable version of the time of that tweet.

<span class=""published"" title=""2008-12-18T22:01:27+00:00"">about 3 hours ago</span> 

The spec for datetime is still draft at the minute and there is still ongoing conversation around the right format and semantics for representing date and time in microformats, see the datetime design pattern for details. 

The hAtom example page shows the minimal changes required to implement hAtom on well formed blog post content and for other less well behaved content. You have the information already in your content publication systems, this is not some additional onerous content entry task, simply some template formatting.

I started to see this as a serious issue after reading Stewart Brand’s Clock of the Long Now about five years ago. Brand’s book explores the issues of short term thinking that permeate our society, thinking beyond the end of the financial year is a stretch for many people. The Long Now has a world view of a 10,000 year timeframe, see http://longnow.org/ for much more information. Freebase from Long Now Board member Danny Hillis, supports dates quite well – see the entry for A Christmas Carol.

In conclusion

I feel we should be making it easier for people searching for our content in the future. We’ve moved through tagging content and on to geo-tagging content. Now it is time to get the timestamps right on our content. How do I know when something happened and how can I find other things that happened at the same time is a fair question. This should be something I can satisfy simply and easily. There are a range of tools available to us in either hAtom or RDF to specify time accurately alongside the content, so what is stopping you?

Thinking of the long term it is hard for us to know now what will be of relevance for future generations, so we should aim to raise the floor for publishing tools so that all content has the right timeframe associated with it. We are moving from publishing words and pictures on the internet to being able to associate publication with an individual via XFN and OpenID. We can associate place quite well too, the last piece of useful metadata is timeframe.",2008,Gavin Bell,gavinbell,2008-12-20T00:00:00+00:00,https://24ways.org/2008/ghosts-on-the-internet/,ux
109,Geotag Everywhere with Fire Eagle,"A note from the editors:  Since this article was written Yahoo! has retired the Fire Eagle service.
                
                
                      
                Location, they say, is everywhere. Everyone has one, all of the time. But on the web, it’s taken until this year to see the emergence of location in the applications we use and build.

The possibilities are broad. Increasingly, mobile phones provide SDKs to approximate your location wherever you are, browser extensions such as Loki and Mozilla’s Geode provide browser-level APIs to establish your location from the proximity of wireless networks to your laptop. Yahoo’s Brickhouse group launched Fire Eagle, an ambitious location broker enabling people to take their location from any of these devices or sources, and provide it to a plethora of web services. It enables you to take the location information that only your iPhone knows about and use it anywhere on the web.

That said, this is still a time of location as an emerging technology. Fire Eagle stores your location on the web (protected by application-specific access controls), but to try and give an idea of how useful and powerful your location can be — regardless of the services you use now — today’s 24ways is going to build a bookmarklet to call up your location on demand, in any web application.

Location Support on the Web

Over the past year, the number of applications implementing location features has increased dramatically. Plazes and Brightkite are both full featured social networks based around where you are, whilst Pownce rolled in Fire Eagle support to allow geotagging of all the content you post to their microblogging service. Dipity’s beautiful timeline shows for you moving from place to place and Six Apart’s activity stream for Movable Type started exposing your movements.

The number of services that hook into Fire Eagle will increase as location awareness spreads through the developer community, but you can use your location on other sites indirectly too.

Consider Flickr. Now world renowned for their incredible mapping and places features, geotagging on Flickr started out as a grassroots extension of regular tagging. That same technique can be used to start rolling geotagging in any publishing platform you come across, for any kind of content. Machine-tags (geo:lat= and geo:lon=) and the adr and geo microformats can be used to enhance anything you write with location information.

A crash course in avian inflammability

Fire Eagle is a location store. A broker between services and devices which provide location and those which consume it. It’s a switchboard that controls which pieces of your location different applications can see and use, and keeps hidden anything you want kept private. A blog widget that displays your current location in public can be restricted to display just your current city, whilst a service that provides you with a list of the nearest ATMs will operate better with a precise street address. 

Even if your iPhone tells Fire Eagle exactly where you are, consuming applications only see what you want them to see. That’s important for users to realise that they’re in control, but also important for application developers to remember that you cannot rely on having super-accurate information available all the time. You need to build location aware applications which degrade gracefully, because users will provide fuzzier information — either through choice, or through less accurate sources.

Application specific permissions are controlled through an OAuth API. Each application has a unique key, used to request a second, user-specific key that permits access to that user’s information. You store that user key and it remains valid until such a time as the user revokes your application’s access. Unlike with passwords, these keys are unique per application, so revoking the access rights of one application doesn’t break all the others.

Building your first Fire Eagle app; Geomarklet

Fire Eagle’s developer documentation can take you through examples of writing simple applications using server side technologies (PHP, Python). Here, we’re going to write a client-side bookmarklet to make your location available in every site you use. It’s designed to fast-track the experience of  having location available everywhere on web, and show you how that can be really handy. Hopefully, this will set you thinking about how location can enhance the new applications you build in 2009.

An oddity of bookmarklets

Bookmarklets (or ‘favlets’, for those of an MSIE persuasion) are a strange environment to program in. Critically, you have no persistent storage available. As such, using token-auth APIs in a static environment requires you to build you application in a slightly strange way; authing yourself in advance and then hardcoding the keys into your script.

Get started

Before you do anything else, go to http://fireeagle.com and log in, get set up if you need to and by all means take a look around. Take a look at the mobile updaters section of the application gallery and perhaps pick out an app that will update Fire Eagle from your phone or laptop.

Once that’s done, you need to register for an application key in the developer section. Head straight to /developer/create and complete the form. Since you’re building a standalone application, choose ‘Auth for desktop applications’ (rather than web applications), and select that you’ll be ‘accessing location’, not updating.

At the end of this process, you’ll have two application keys, a ‘Consumer Key’ and a ‘Consumer Secret’, which look like these:

 
    Consumer Key
    luKrM9U1pMnu
    Consumer Secret
    ZZl9YXXoJX5KLiKyVrMZffNEaBnxnd6M
 

These keys combined allow your application to make requests to Fire Eagle.

Next up, you need to auth yourself; granting your new application permission to use your location. Because bookmarklets don’t have local storage, you can’t integrate the auth process into the bookmarklet itself — it would have no way of storing the returned key. Instead, I’ve put together a simple web frontend through which you can auth with your application.

Head to Auth me, Amadeus!, enter the application keys you just generated and hit ‘Authorize with Fire Eagle’. You’ll be taken to the Fire Eagle website, just as in regular Fire Eagle applications, and after granting access to your app, be redirected back to Amadeus which will provide you your user tokens. These tokens are used in subsequent requests to read your location.

And, skip to the end…

The process of building the bookmarklet, making requests to Fire Eagle, rendering it to the page and so forth follows, but if you’re the impatient type, you might like to try this out right now. Take your four API keys from above, and drag the following link to your Bookmarks Toolbar; it contains all the code described below. Before you can use it, you need to edit in your own API keys. Open your browser’s bookmark editor and where you find text like ‘YOUR_CONSUMER_KEY_HERE’, swap in the corresponding key you just generated.

Get Location

Bookmarklet Basics

To start on the bookmarklet code, set out a basic JavaScript module-pattern structure:

var Geomarklet = function() {
	return ({
		callback: function(json) {},
		run: function() {}
	});
};
Geomarklet.run();

Next we’ll add the keys obtained in the setup step, and also some basic Fire Eagle support objects:

var Geomarklet = function() {
	var Keys = {
			consumer_key: 'IuKrJUHU1pMnu',
			consumer_secret: 'ZZl9YXXoJX5KLiKyVEERTfNEaBnxnd6M',
			user_token: 'xxxxxxxxxxxx',
			user_secret: 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
	};
	var LocationDetail = {
			EXACT: 0,
			POSTAL: 1,
			NEIGHBORHOOD: 2,
			CITY: 3,
			REGION: 4,
			STATE: 5,
			COUNTRY: 6
	};
	var index_offset;
	return ({
		callback: function(json) {},
		run: function() {}
	});
};
Geomarklet.run();

The Location Hierarchy

A successful Fire Eagle query returns an object called the ‘location hierarchy’. Depending on the level of detail shared, the index of a particular piece of information in the array will vary. The LocationDetail object maps the array indices of each level in the hierarchy to something comprehensible, whilst the index_offset variable is an adjustment based on the detail of the result returned.

The location hierarchy object looks like this, providing a granular breakdown of a location, in human consumable and machine-friendly forms.

""user"": {
		""location_hierarchy"": [{
			""level"": 0,
			""level_name"": ""exact"",
			""name"": ""707 19th St, San Francisco, CA"",
			""normal_name"": ""94123"",
			""geometry"": {
					""type"": ""Point"",
					""coordinates"": [ - 0.2347530752, 67.232323]
			},
			""label"": null,
			""best_guess"": true,
			""id"": ,
			""located_at"": ""2008-12-18T00:49:58-08:00"",
			""query"": ""q=707%2019th%20Street,%20Sf""
		},
		{
				""level"": 1,
				""level_name"": ""postal"",
				""name"": ""San Francisco, CA 94114"",
				""normal_name"": ""12345"",
				""woeid"": ,
				""place_id"": """",
				""geometry"": {
						""type"": ""Polygon"",
						""coordinates"": [],
						""bbox"": []
				},
				""label"": null,
				""best_guess"": false,
				""id"": 59358791,
				""located_at"": ""2008-12-18T00:49:58-08:00""
		},
		{
				""level"": 2,
				""level_name"": ""neighborhood"",
				""name"": ""The Mission, San Francisco, CA"",
				""normal_name"": ""The Mission"",
				""woeid"": 23512048,
				""place_id"": ""Y12JWsKbApmnSQpbQg"",
				""geometry"": {
						""type"": ""Polygon"",
						""coordinates"": [],
						""bbox"": []
				},
				""label"": null,
				""best_guess"": false,
				""id"": 59358801,
				""located_at"": ""2008-12-18T00:49:58-08:00""
			},
		}

In this case the first object has a level of 0, so the index_offset is also 0.

Prerequisites

To query Fire Eagle we call in some existing libraries to handle the OAuth layer and the Fire Eagle API call. Your bookmarklet will need to add the following scripts into the page:


	The SHA1 encryption algorithm
	The OAuth wrapper
	An extension for the OAuth wrapper
	The Fire Eagle wrapper itself


When the bookmarklet is first run, we’ll insert these scripts into the document. We’re also inserting a stylesheet to dress up the UI that will be generated.

If you want to follow along any of the more mundane parts of the bookmarklet, you can  download the full source code.

Rendering

This bookmarklet can be extended to support any formatting of your location you like, but for sake of example I’m going to build three common formatters that you’ll find useful for common location scenarios: Sites which already ask for your location; and in publishing systems that accept tags or HTML mark-up.

All the rendering functions are items in a renderers object, so they can be iterated through easily, making it trivial to add new formatting functions as your find new use cases (just add another function to the object).

var renderers = {
geotag: function(user) {
	if(LocationDetail.EXACT !== index_offset) {
			return false;
	}
	else {
		var coords =
			user.location_hierarchy[LocationDetail.EXACT].geometry.coordinates;
		return ""geo:lat="" + coords[0] + "", geo:lon="" + coords[1];
	}
},
city: function(user) {
	if(LocationDetail.CITY < index_offset) {
		return false;
	}
	else {
		return user.location_hierarchy[LocationDetail.CITY - index_offset].name; 
	}						 
}

You should always fail gracefully, and in line with catering to users who choose not to share their location precisely, always check that the location has been returned at the level you require. Geotags are expected to be precise, so if an exact location is unavailable, returning false will tell the rendering aspect of the bookmarklet to ignore the function altogether.

These first two are quite simple, geotag returns geo:lat=-0.2347530752, geo:lon=67.232323 and city returns San Francisco, CA.

This final renderer creates a chunk of HTML using the adr and geo microformats, using all available aspects of the location hierarchy, and can be used to geotag any content you write on your blog or in comments:

html: function(user) {
	var geostring = '';
	var adrstring = '';
	var adr = [];		 
	adr.push('<p class=""adr"">');
	// city
	if(LocationDetail.CITY >= index_offset) {
		adr.push(
			'\n		 <span class=""locality"">'
		+ user.location_hierarchy[LocationDetail.CITY-index_offset].normal_name
		+ '</span>,'
		);
	}
	// county
	if(LocationDetail.REGION >= index_offset) {
		adr.push(
			'\n		 <span class=""region"">' 
		+ user.location_hierarchy[LocationDetail.REGION-index_offset].normal_name
		+ '</span>,'
			);
	}
	// locality
	if(LocationDetail.STATE >= index_offset) {
		adr.push(
			'\n		 <span class=""region"">'
		+ user.location_hierarchy[LocationDetail.STATE-index_offset].normal_name
		+ '</span>,'
		);
	}
	// country
	if(LocationDetail.COUNTRY >= index_offset) {
		adr.push(
			'\n		 <span class=""country-name"">'
		+ user.location_hierarchy[LocationDetail.COUNTRY-index_offset].normal_name
		+ '</span>'
		);
	}
	// postal
	if(LocationDetail.POSTAL >= index_offset) {
		adr.push(
			'\n		 <span class=""postal-code"">'
		+ user.location_hierarchy[LocationDetail.POSTAL-index_offset].normal_name
		+ '</span>,'
		);
	}
	adr.push('\n</p>\n');
	adrstring = adr.join('');
	if(LocationDetail.EXACT === index_offset) {
		var coords = 
			user.location_hierarchy[LocationDetail.EXACT].geometry.coordinates;
		geostring = '<p class=""geo"">'
			+'\n		<span class=""latitude"">'
			+ coords[0]
			+ '</span>;'
			+ '\n		 <span class=""longitude"">'
			+ coords[1]
			+ '</span>\n</p>\n';
	}
	return (adrstring + geostring);
}

Here we check the availability of every level of location and build it into the adr and geo patterns as appropriate. Just as for the geotag function, if there’s no exact location the geo markup won’t be returned.

Finally, there’s a rendering method which creates a container for all this data, renders all the applicable location formats and then displays them in the page for a user to copy and paste. You can throw this together with DOM methods and some simple styling, or roll in some components from YUI or JQuery to handle drawing full featured overlays.

You can see this simple implementation for rendering in the full source code.

Make the call

With a framework in place to render Fire Eagle’s location hierarchy, the only thing that remains is to actually request your location. Having already authed through Amadeus earlier, that’s as simple as instantiating the Fire Eagle JavaScript wrapper and making a single function call. It’s a big deal that whilst a lot of new technologies like OAuth add some complexity and require new knowledge to work with, APIs like Fire Eagle are really very simple indeed.

return {
	run: function() {
		insert_prerequisites();
		setTimeout(
			function() {
				var fe = new FireEagle(
					Keys.consumer_key,
					Keys.consumer_secret,
					Keys.user_token,
					Keys.user_secret
				);
				var script = document.createElement('script');
				script.type = 'text/javascript';
				script.src = fe.getUserUrl(
					FireEagle.RESPONSE_FORMAT.json,
					'Geomarklet.callback'
				);
				document.body.appendChild(script);
			},
			2000
		);
	},
	callback: function(json) {
		if(json.rsp && 'fail' == json.rsp.stat) {
			alert('Error ' + json.rsp.code + "": "" + json.rsp.message);
		}
		else {
			index_offset = json.user.location_hierarchy[0].level;						 
			draw_selector(json);
		}
	}
};

We first insert the prerequisite scripts required for the Fire Eagle request to function, and to prevent trying to instantiate the FireEagle object before it’s been loaded over the wire, the remaining instantiation and request is wrapped inside a setTimeout delay.

We then create the request URL, referencing the Geomarklet.callback callback function and then append the script to the document body — allowing a cross-domain request.

The callback itself is quite simple. Check for the presence and value of rsp.status to test for errors, and display them as required. If the request is successful set the index_offset — to adjust for the granularity of the location hierarchy — and then pass the object to the renderer.

The result? When Geomarklet.run() is called, your location from Fire Eagle is read, and each renderer displayed on the page in an easily copy and pasteable form, ready to be used however you need.

Deploy

The final step is to convert this code into a long string for use as a bookmarklet. Easiest for Mac users is the JavaScript bundle in TextMate — choose Bundles: JavaScript: Copy as Bookmarklet to Clipboard. Then create a new ‘Get Location’ bookmark in your browser of choice and paste in.

Those without TextMate can shrink their code down into a single line by first running their code through the JSLint tool (to ensure the code is free from errors and has all the required semi-colons) and then use a find-and-replace tool to remove line breaks from your code (or even run your code through JSMin to shrink it down).

With the bookmarklet created and added to your bookmarks bar, you can now call up your location on any page at all. Get a feel for a web where your location is just another reliable part of the browsing experience.

Where next?

So, the Geomarklet you’ve been guided through is a pretty simple premise and pretty simple output. But from this base you can start to extend: Add code that will insert each of the location renderings directly into form fields, perhaps, or how about site-specific handlers to add your location tags into the correct form field in Wordpress or Tumblr?

111,Geometric Background Patterns,"When the design is finished and you’re about to start the coding process, you have to prepare your graphics. If you’re working with a pattern background you need to export only the repeating fragment. It can be a bit tricky to isolate a fragment to achieve a seamless pattern background. For geometric patterns there is a method I always follow and that I want to share with you. Take for example a perfect 45° diagonal line pattern. 



How do you define this pattern fragment so it will be rendered seamlessly?



Here is the method I usually follow to avoid a mismatch. First, zoom in so you see enough detail and you can distinguish the pixels. Select the Rectangular Marquee Selection tool and start your selection at the intersection of 2 different colors of a diagonal line. Hold down the Shift key while dragging so you drag a perfect square.



Release the mouse when you reach the exact same intesection (as your starting) point at the top right. 



Copy this fragment (using Copy Merged: Cmd/Ctrl + Shift + C) and paste the fragment in a new layer. Give this layer the name ‘pattern’. Now hold down the Command Key (Control Key on Windows) and click on the ‘pattern’ layer in the Layers Palette  to select the fragment. Now go to Edit > Define Pattern, enter a name for your pattern and click OK. Test your pattern in a new document. Create a new document of 600 px by 400px, hit Cmd/Ctrl + A and go to Edit > Fill… and choose your pattern. If the result is OK, you have created a perfect pattern fragment.



Below you see this pattern enlarged. The guides show the boundaries of the pattern fragment and the red pixels are the reference points. The red pixels at the top right, bottom right and bottom left should match the red pixel at the top left.



This technique should work for every geometric pattern. Some patterns are easier than others, but this, and the Photoshop pattern fill test, has always been my guideline.

Other geometric pattern examples

Example 1

Not all geometric pattern fragments are squares. Some patterns look easy at first sight, because they look very repetitive, but they can be a bit tricky.



Zoomed in pattern fragment with point of reference shown:



Example 2

Some patterns have a clear repeating point that can guide you, such as the blue small circle of this pattern as you can see from this zoomed in screenshot:

Example 3

The different diagonal colors makes a bit more tricky to extract the correct pattern fragment.

101,Easing The Path from Design to Development,"As a web developer, I have the pleasure of working with a lot of different designers. There has been a lot of industry discussion of late about designers and developers, focusing on how different we sometimes are and how the interface between our respective phases of a project (that is to say moving from a design phase into production) can sometimes become a battleground.

I don’t believe it has to be a battleground. It’s actually more like being a dance partner – our steps are different, but as long as we know our own part and have a little knowledge of our partner’s steps, it all goes together to form a cohesive dance. Albeit with less spandex and fewer sequins (although that may depend on the project in question).

As the process usually flows from design towards development, it’s most important that designers have a little knowledge of how the site is going to be built. At the specialist web development agency I’m part of, we find that designs that have been well considered from a technical perspective help to keep the project on track and on budget.

Based on that experience, I’ve put together my checklist of things that designers should consider before handing their work over to a developer to build.

Layout

One rookie mistake made by traditionally trained designers transferring to the web is to forget a web browser is not a fixed medium. Unlike designing a magazine layout or a piece of packaging, there are lots of available options to consider. Should the layout be fluid and resize with the window, or should it be set to a fixed width? If it’s fluid, which parts expand and which not? If it’s fixed, should it sit in the middle of the window or to one side?

If any part of the layout is going to be flexible (get wider and narrower as required), consider how any graphics are affected. Images don’t usually look good if displayed at anything other that their original size, so should they behave? If a column is going to get wider than it’s shown in the Photoshop comp, it may be necessary to provide separate wider versions of any background images.

Text size and content volume

A related issue is considering how the layout behaves with both different sizes of text and different volumes of content. Whilst text zooming rather than text resizing is becoming more commonplace as the default behaviour in browsers, it’s still a fundamentally important principal of web design that we are suggesting and not dictating how something should look. Designs must allow for a little give and take in the text size, and how this affects the design needs to be taken into consideration.

Keep in mind that the same font can display differently in different places and platforms. Something as simple as Times will display wider on a Mac than on Windows. However, the main impact of text resizing is the change in how much vertical space copy takes up. This is particularly important where space is limited by the design (making text bigger causes many more problems than making text smaller). Each element from headings to box-outs to navigation items and buttons needs to be able to expand at least vertically, if not horizontally as well. This may require some thought about how elements on the page may wrap onto new lines, as well as again making sure to provide extended versions of any graphical elements.

Similarly, it’s rare theses days to know exactly what content you’re working with when a site is designed. Many, if not most sites are designed as a series of templates for some kind of content management system, and so designs cannot be tweaked around any specific item of content. Designs must be able to cope with both much greater and much lesser volumes of content that might be thrown in at the lorem ipsum phase.

Particular things to watch out for are things like headings (how do they wrap onto multiple lines) and any user-generated items like usernames. It can be very easy to forget that whilst you might expect something like a username to be 8-12 characters, if the systems powering your site allow for 255 characters they’ll always be someone who’ll go there. Expect them to do so.

Again, if your site is content managed or not, consider the possibility that the structure might be expanded in the future. Consider how additional items might be added to each level of navigation. Whilst it’s rarely desirable to make significant changes without revisiting the site’s information architecture more thoroughly, it’s an inevitable fact of life that the structure needs a little bit of flexibility to change over time.

Interactions with and without JavaScript

A great number of sites now make good use of JavaScript to streamline the user interface and make everything just that touch more usable. Remember, though, that any developer worth their salt will start by building the interface without JavaScript, get it all working, and then layer that JavaScript on top. This is to allow for users viewing the site without JavaScript available or enabled in their browser.

Designers need to consider both states of any feature they’re designing – how it looks and functions with and without JavaScript. If the feature does something fancy with Ajax, consider how the same can be achieved with basic HTML forms, links and intermediary pages. These all need to be designed, because this is how some of your users will interact with the site.

Logged in and logged out states

When designing any type of web application or site that has a membership system – that is to say users can create an account and log into the site – the design will need to consider how any element is presented in both logged in and logged out states. For some items there’ll be no difference, whereas for others there may be considerable differences.

Should an item be hidden completely not logged out users? Should it look different in some way? Perhaps it should look the same, but prompt the user to log in when they interact with it. If so, what form should that prompt take on and how does the user progress through the authentication process to arrive back at the task they were originally trying to complete?

Couple logged in and logged out states with the possible absence of JavaScript, and every feature needs to be designed in four different states:


	Logged out with JavaScript available
	Logged in with JavaScript available
	Logged out without JavaScript available
	Logged in without JavaScript available


Fonts

There are three main causes of war in this world; religions, politics and fonts. I’ve said publicly before that I believe the responsibility for this falls squarely at the feet of Adobe Photoshop. Photoshop, like a mistress at a brothel, parades a vast array of ropey, yet strangely enticing typefaces past the eyes of weak, lily-livered designers, who can’t help but crumble to their curvy charms.

Yet, on the web, we have to be a little more restrained in our choice of typefaces. The purest solution is always to make the best use of the available fonts, but this isn’t always the most desirable solution from a design point of view. There are several technical solutions such as techniques that utilise Flash (like sIFR), dynamically generated images and even canvas in newer browsers. Discuss the best approach with your developer, as every different technique has different trade-offs, and this may impact the design in other ways.

Messaging

Any site that has interactive elements, from a simple contact form through to fully featured online software application, involves some kind of user messaging. By this I mean the error messages when something goes wrong and the success and thank-you messages when something goes right. These typically appear as the result of an interaction, so are easy to forget and miss off a Photoshop comp.

For every form, consider what gets displayed to the user if they make a mistake or miss something out, and also what gets displayed back when the interaction is successful. What do they see and where do the go next?

With Ajax interactions, the user doesn’t get any visual feedback of the site waiting for a response from the server unless you design it that way. Consider using a ‘waiting’ or ‘in progress’ spinner to give the user some visual feedback of any background processes. How should these look? How do they animate?

Similarly, also consider the big error pages like a 404. With luck, these won’t often be seen, but it’s at the point that they are when careful design matters the most.

Form fields

Depending on the visual style of your site, the look of a browser’s default form fields and buttons can sometimes jar. It’s understandable that many a designer wants to change the way they look. Depending on the browser in question, various things can be done to style form fields and their buttons (although it’s not as flexible as most would like).

A common request is to replace the default buttons with a graphical button. This is usually achievable in most cases, although it’s not easy to get a consistent result across all browsers – particularly when it comes to vertical positioning and the space surrounding the button. If the layout is very precise, or if space is at a premium, it’s always best to try and live with the browser’s default form controls.

Whichever way you go, it’s important to remember that in general, each form field should have a label, and each form should have a submit button. If you find that your form breaks either of those rules, you should double check.

Practical tips for handing files over

There are a couple of basic steps that a design can carry out to make sure that the developer has the best chance of implementing the design exactly as envisioned.

If working with Photoshop of Fireworks or similar comping tool, it helps to group and label layers to make it easy for a developer to see which need to be turned on and off to get to isolate parts of the page and different states of the design. Also, if you don’t work in the same office as your developer (and so they can’t quickly check with you), provide a PDF of each page and state so that your developer can see how each page should look aside from any confusion with quick layers are switched on or off. These also act as a handy quick reference that can be used without firing up Photoshop (which can kill both productivity and your machine).

Finally, provide a colour reference showing the RGB values of all the key colours used throughout the design. Without this, the developer will end up colour-picking from the comps, and could potentially end up with different colours to those you intended. Remember, for a lot of developers, working in a tool like Photoshop is like presenting a designer with an SSH terminal into a web server. It’s unfamiliar ground and easy to get things wrong. Be the expert of your own domain and help your colleagues out when they’re out of their comfort zone. That goes both ways.

In conclusion

When asked the question of how to smooth hand-over between design and development, almost everyone who has experienced this situation could come up with their own list. This one is mine, based on some of the more common experiences we have at edgeofmyseat.com. So in bullet point form, here’s my checklist for handing a design over.


	Is the layout fixed, or fluid?
	Does each element cope with expanding for larger text and more content?
	Are all the graphics large enough to cope with an area expanding?
	Does each interactive element have a state for with and without JavaScript?
	Does each element have a state for logged in and logged out users?
	How are any custom fonts being displayed? (and does the developer have the font to use?)
	Does each interactive element have error and success messages designed?
	Do all form fields have a label and each form a submit button?
	Is your Photoshop comp document well organised?
	Have you provided flat PDFs of each state?
	Have you provided a colour reference?
	Are we having fun yet?",2008,Drew McLellan,drewmclellan,2008-12-01T00:00:00+00:00,https://24ways.org/2008/easing-the-path-from-design-to-development/,process
120,Easier Page States for Wireframes,"When designing wireframes for web sites and web apps, it is often overlooked that the same ‘page’ can look wildly different depending on its context. A logged-in page will look different from a logged-out page; an administrator’s view may have different buttons than a regular user’s view; a power user’s profile will be more extensive than a new user’s.

These different page states need designing at some point, especially if the wireframes are to form a useful communication medium between designer and developer. Documenting the different permutations can be a time consuming exercise involving either multiple pages in one’s preferred box-and-arrow software, or a fully fledged drawing containing all the possible combinations annotated accordingly.

Enter interactive wireframes and Polypage

Interactive wireframes built in HTML are a great design and communication tool. They provide a clickable prototype, running in the browser as would the final site. As such they give a great feel for how the site will be to use. Once you add in the possibilities of JavaScript and a library such as jQuery, they become even more flexible and powerful.

Polypage is a jQuery plugin which makes it really easy to design multiple page states in HTML wireframes. There’s no JavaScript knowledge required (other than cutting and pasting in a few lines). The page views are created by simply writing all the alternatives into your HTML page and adding special class names to apply state and conditional view logic to the various options. 

When the page is loaded Polypage automatically detects the page states defined by the class names and creates a control bar enabling the user to toggle page states with the click of a mouse or the clack of a keyboard.



Using cookies by way of the jQuery cookie plugin, Polypage retains the view state throughout your prototype. This means you could navigate through your wireframes as if you were logged out; as if you were logged in as an administrator; with notes on or off; or with any other view or state you might require. The possibilities are entirely up to you.

How does it work?

Firstly you need to link to jQuery, the jQuery cookie plugin and to Polypage. Something like this:

<script src=""javascripts/jquery-1.2.6.min.js"" type=""text/javascript""></script>
<script src=""javascripts/cookie.jquery.js"" type=""text/javascript""></script>
<script src=""javascripts/polypage.jquery.js"" type=""text/javascript""></script>

Then you need to initialise Polypage on page load using something along these lines:

<script type=""text/javascript"">
	$(document).ready(function() {
		$.polypage.init();
	});
</script>

Next you need to define the areas of your wireframe which are particular to a given state or view. Do this by applying classes beginning with pp_. Polypage will ignore all other classes in the document.

The pp_ prefix should be followed by a state name. This can be any text string you like, bearing in mind it will appear in the control bar. Typical page states might include ‘logged_in’, ‘administrator’ or ‘group_owner’. A complete class name would therefore look something like pp_logged_in.

Examples

If a user is logged in, you might want to specify an option for him or her to sign out. Using Polypage, this could be put in the wireframe as follows:

<a href=""logout"" class=""pp_logged_in""> Sign out </a>

Polypage will identify the pp_logged_in class on the link and hide it (as the ‘Sign out’ link should only be shown when the page is in the ‘logged in’ view). Polypage will then automatically write a ‘logged in’ toggle to the control bar, enabling you to show or hide the ‘Sign out’ link by toggling the ‘logged in’ view. The same will apply to all content marked with a pp_logged_in class.

States can also be negated by adding a not keyword to the class name. For example you might want to provide a log in link for users who are not signed in. Using Polypage, you would insert the not keyword after the pp prefix as follows:

<a href=""login"" class=""pp_not_logged_in""> Login </a>

Again Polypage identifies the pp prefix but this time sees that the ‘Login’ link should not be shown when the ‘logged in’ state is selected.

States can also be joined together to add some basic logic to pages. The syntax follows natural language and uses the or and and keywords in addition to the afore-mentioned not. Some examples would be pp_logged_in_and_admin, pp_admin_or_group_owner and pp_logged_in_and_not_admin.

Finally, you can set default states for a page by passing an array to the polypage.init() function like this:

$.polypage.init(['logged_in', 'admin']);

You can see a fully fledged example in this fictional social network group page. The example page defaults to a logged in state. You can see the logged out state by toggling ‘logged in’ off in the Polypage control bar. There are also views specified for a group member, a group admin, a new group and notes. 

Where can I get hold of it?

You can download the current version from GitHub.

Polypage was originally developed by Clearleft and New Bamboo, with particular contributions from Andy Kent and Natalie Downe. It has been used in numerous real projects, but it is still an early release so there is bound to be room for improvement. We’re pleased to say that Polypage is now an open source project so any feedback, particularly by way of actual improvements, is extremely welcome.",2008,Richard Rutter,richardrutter,2008-12-11T00:00:00+00:00,https://24ways.org/2008/easier-page-states-for-wireframes/,process
105,Contract Killer,"When times get tough, it can often feel like there are no good people left in the world, only people who haven’t yet turned bad. These bad people will go back on their word, welch on a deal, put themselves first. You owe it to yourself to stay on top. You owe it to yourself to ensure that no matter how bad things get, you’ll come away clean. You owe it yourself and your business not to be the guy lying bleeding in an alley with a slug in your gut.

But you’re a professional, right? Nothing bad is going to happen to you.

You’re a good guy. You do good work for good people.

Think again chump.

Maybe you’re a gun for hire, a one man army with your back to the wall and nothing standing between you and the line at a soup kitchen but your wits. Maybe you work for the agency, or like me you run one of your own. Either way, when times get tough and people get nasty, you’ll need more than a killer smile to save you. You’ll need a killer contract too.

It was exactly ten years ago today that I first opened my doors for business. In that time I’ve thumbed through enough contracts to fill a filing cabinet. I’ve signed more contracts than I can remember, many so complicated that I should have hired a lawyer (or detective) to make sense of their complicated jargon and solve their cross-reference puzzles. These documents had not been written to be understood on first reading but to spin me around enough times so as to give the other player the upper-hand.


If signing a contract I didn’t fully understand made me a stupid son-of-a-bitch, not asking my customers to sign one just makes me plain dumb. I’ve not always been so careful about asking my customers to sign contracts with me as I am now. Somehow in the past I felt that insisting on a contract went against the friendly, trusting relationship that I like to build with my customers. Most of the time the game went my way. On rare the occasions when a fight broke out, I ended up bruised and bloodied. I learned that asking my customers to sign a contract matters to both sides, but what also matters to me is that these contracts should be more meaningful, understandable and less complicated than any of those that I have ever autographed.


Writing a killer contract

If you are writing a contract between you and your customers it doesn’t have to conform to the seemingly standard format of jargon and complicated legalese. You can be creative. A killer contract will clarify what is expected of both sides and it can also help you to communicate your approach to doing business. It will back-up your brand values and help you to build a great relationship between you and your customers. In other words, a creative contract can be a killer contract.


Your killer contract should cover:


	A simple overview of who is hiring who, what they are being hired to do, when and for how much
	What both parties agree to do and what their respective responsibilities are
	The specifics of the deal and what is or isn’t included in the scope
	What happens when people change their minds (as they almost always do)
	A simple overview of liabilities and other legal matters
	You might even include a few jokes


To help you along, I will illustrate those bullet points by pointing both barrels at the contract that I wrote and have been using at Stiffs & Nonsense for the past year. My contract has been worth its weight in lead and you are welcome to take all or any part of it to use for yourself. It’s packing a creative-commons attribution share-a-like license. That means you are free to re-distribute it, translate it and otherwise re-use it in ways I never considered. In return I only ask you mention my name and link back to this article. As I am only an amateur detective, you should have it examined thoroughly by your own, trusted legal people if you use it.

NB: The specific details of this killer contract work for me and my customers. That doesn’t mean that they will work for you and yours. The ways that I handle design revisions, testing, copyright ownership and other specifics are not the main focus of this article. That you handle each of them carefully when you write your own killer contract is.

Kiss Me, Deadly

Setting a tone and laying foundations for agreement

The first few paragraphs of a killer contract are the most important. Just like a well thought-out web page, these first few words should be simple, concise and include the key points in your contract. As this is the part of the contract that people absorb most easily, it is important that you make it count. Start by setting the overall tone and explaining how your killer contract is structured and why it is different.



	We will always do our best to fulfill your needs and meet your goals, but sometimes it is best to have a few simple things written down so that we both know what is what, who should do what and what happens if stuff goes wrong. In this contract you won’t find complicated legal terms or large passages of unreadable text. We have no desire to trick you into signing something that you might later regret. We do want what’s best for the safety of both parties, now and in the future.

	In short

	You ([customer name]) are hiring us ([company name]) located at [address] to [design and develop a web site] for the estimated total price of [total] as outlined in our previous correspondence. Of course it’s a little more complicated, but we’ll get to that.


The Big Kill

What both parties agree to do

Have you ever done work on a project in good faith for a junior member of a customer’s team, only to find out later that their spending hadn’t been authorized? To make damn sure that does not happen to you,  you should ask your customer to confirm that not only are they authorized to enter into your contract but that they will fulfill all of their obligations to help you meet yours. This will help you to avoid any gunfire if, as deadline day approaches, you have fulfilled your side of the bargain but your customer has not come up with the goods.



	As our customer, you have the power and ability to enter into this contract on behalf of your company or organization. You agree to provide us with everything that we need to complete the project including text, images and other information as and when we need it, and in the format that we ask for. You agree to review our work, provide feedback and sign-off approval in a timely manner too. Deadlines work two ways and you will also be bound by any dates that we set together. You also agree to stick to the payment schedule set out at the end of this contract.

	We have the experience and ability to perform the services you need from us and we will carry them out in a professional and timely manner. Along the way we will endeavor to meet all the deadlines set but we can’t be responsible for a missed launch date or a deadline if you have been late in supplying materials or have not approved or signed off our work on-time at any stage. On top of this we will also maintain the confidentiality of any information that you give us.


My Gun Is Quick

Getting down to the nitty gritty

What appear at first to be a straight-forward projects can sometimes turn long and complicated and unless you play it straight from the beginning your relationship with your customer can suffer under the strain. Customers do, and should have the opportunity to, change their minds and give you new assignments. After-all, projects should be flexible and few customers know from the get-go exactly what they want to see. If you handle this well from the beginning you will help to keep yourself and your customers from becoming frustrated. You will also help yourself to dodge bullets in the event of a fire-fight.



	We will create designs for the look-and-feel, layout and functionality of your web site. This contract includes one main design plus the opportunity for you to make up to two rounds of revisions. If you’re not happy with the designs at this stage, you will pay us in full for all of the work that we have produced until that point and you may either cancel this contract or continue to commission us to make further design revisions at the daily rate set out in our original estimate.

	We know from plenty of experience that fixed-price contracts are rarely beneficial to you, as they often limit you to your first idea about how something should look, or how it might work. We don’t want to limit  either your options or your opportunities to change your mind.

	The estimate/quotation prices at the beginning of this document are based on the number of days that we estimate we’ll need to accomplish everything that you have told us you want to achieve. If you do want to change your mind, add extra pages or templates or even add new functionality, that won’t be a problem. You will be charged the daily rate set out in the estimate we gave you. Along the way we might ask you to put requests in writing so we can keep track of changes.


As I like to push my luck when it comes to CSS, it never hurts to head off the potential issue of progressive enrichment right from the start. You should do this too. But don’t forget that when it comes to technical matters your customers may have different expectations or understanding, so be clear about what you will and won’t do.



	If the project includes XHTML or HTML markup and CSS templates, we will develop these using valid XHTML 1.0 Strict markup and CSS2.1 + 3 for styling. We will test all our markup and CSS in current versions of all major browsers including those made by Apple, Microsoft, Mozilla and Opera. We will also test to ensure that pages will display visually in a ‘similar’, albeit not necessarily an identical way, in Microsoft Internet Explorer 6 for Windows as this browser is now past it’s sell-by date.

	We will not test these templates in old or abandoned browsers, for example Microsoft Internet Explorer 5 or 5.5 for Windows or Mac, previous versions of Apple’s Safari, Mozilla Firefox or Opera unless otherwise specified. If you need to show the same or similar visual design to visitors using these older browsers, we will charge you at the daily rate set out in our original estimate for any necessary additional code and its testing.


The Twisted Thing

It is not unheard of for customers to pass off stolen goods as their own. If this happens, make sure that you are not the one left holding the baby. You should also make it clear who owns the work that you make as customers often believe that because they pay for your time, that they own everything that you produce.


Copyrights


	You guarantee to us that any elements of text, graphics, photos, designs, trademarks, or other artwork that you provide us for inclusion in the web site are either owned by your good selfs, or that you have permission to use them. When we receive your final payment, copyright is automatically assigned as follows:

	You own the graphics and other visual elements that we create for you for this project. We will give you a copy of all files and you should store them really safely as we are not required to keep them or provide any native source files that we used in making them.

	You also own text content, photographs and other data you provided, unless someone else owns them. We own the XHTML markup, CSS and other code and we license it to you for use on only this project.


Vengeance Is Mine!

The fine print

Unless your work is pro-bono, you should make sure that your customers keep you in shoe leather. It is important that your customers know from the outset that they must pay you on time if they want to stay on good terms.


	We are sure you understand how important it is as a small business that you pay the invoices that we send you promptly.  As we’re also sure you’ll want to stay friends, you agree to stick tight to the following payment schedule.

	[Payment schedule]


No killer contract would be complete without you making sure that you are watching your own back. Before you ask your customers to sign, make it clear-cut what your obligations are and what will happen if any part of your killer contract finds itself laying face down in the dirt.



	We can’t guarantee that the functions contained in any web page templates or in a completed web site will always be error-free and so we can’t be liable to you or any third party for damages, including lost profits, lost savings or other incidental, consequential or special damages arising out of the operation of or inability to operate this web site and any other web pages, even if you have advised us of the possibilities of such damages.

	Just like a parking ticket, you cannot transfer this contract to anyone else without our permission. This contract stays in place and need not be renewed.  If any provision of this agreement shall be unlawful, void, or for any reason unenforceable, then that provision shall be deemed severable from this agreement and shall not affect the validity and enforceability of any remaining provisions.

	Phew.

	Although the language is simple, the intentions are serious and this contract is a legal document under exclusive jurisdiction of [English] courts. Oh and don’t forget those men with big dogs.


Survival… Zero!

Take it from me, packing a killer contract will help to keep you safe when times get tough, but you must still keep your wits about you and stay on the right side of the law.

Don’t be a turkey this Christmas.

Be a contract killer.

106,Checking Out: Progress Meters,"It’s the holiday season, so you know what that means: online shopping! When I started developing Web sites back in the 90s, many of my first clients were small local shops wanting to sell their goods online, so I developed many a checkout system. And because of slow dial-up speeds back then, informing the user about where they were in the checkout process was pretty important.

Even though we’re (mostly) beyond the dial-up days, informing users about where they are in a flow is still important. In usability tests at the companies I’ve worked at, I’ve seen time and time again how not adequately informing the user about their state can cause real frustration. This is especially true for two sets of users: mobile users and users of assistive devices, in particular, screen readers.

The progress meter is a very common design solution used to indicate to the user’s state within a flow. On the design side, much effort may go in to crafting a solution that is as visually informative as possible. On the development side, however, solutions range widely. I’ve checked out the checkouts at a number of sites and here’s what I’ve found when it comes to progress meters: they’re sometimes inaccessible and often confusing or unhelpful — all because of the way in which they’re coded. For those who use assistive devices or text-only browsers, there must be a better way to code the progress meter — and there is.

(Note: All code samples are from live sites but have been tweaked to hide the culprits’ identities.)

How not to make progress

A number of sites assemble their progress meters using non- or semi-semantic markup and images with no alternate text. On text-only browsers (like my mobile phone) and to screen readers, this looks and reads like chunks of content with no context given.

<div id=""progress"">
	<img src=""icon_progress_1a.gif"" alt="""">
	<em>Shipping information</em>
	<img src=""icon_progress_arrow.gif"" alt="""">
	<img src=""icon_progress_2a.gif"" alt="""">
	<em>Payment information</em>
	<img src=""icon_progress_arrow.gif"" alt="""" class=""progarrow"">
	<img src=""icon_progress_3b.gif"" alt="""">
	<strong>Place your order</strong>
</div>

In the above example, the third state, “Place your order”, is the current state. But a screen reader may not know that, and my cell phone only displays ""Shipping informationPayment informationPlace your order"". Not good.

Is this progress?

Other sites present the entire progress meter as a graphic, like the following:



Now, I have no problem with using a graphic to render a very stylish progress meter (my sample above is probably not the most stylish example, of course, but you understand my point). What becomes important in this case is the use of appropriate alternate text to describe the image. Disappointingly, sites today have a wide range of solutions, including using no alternate text. Check out these code samples which call progress meter images.

<img src=""checkout_step2.gif"" alt="""">

I think we can all agree that the above is bad, unless you really don’t care whether or not users know where they are in a flow.

<img src=""checkout_step2.gif"" alt=""Shipping information - Payment information - Place your order"">

The alt text in the example above just copies all of the text found in the graphic, but it doesn’t represent the status at all. So for every page in the checkout, the user sees or hears the same text. Sure, by the second or third page in the flow, the user has figured out what’s going on, but she or he had to think about it. I don’t think that’s good.

<img src=""checkout_step2.gif"" alt=""Checkout: Payment information"">

The above probably has the best alternate text out of these examples, because the user at least understands that they’re in the Checkout process, on the Place your order page. But going through the flow with alt text like this, the user doesn’t know how many steps are in the flow.

Semantic progress

Of course, there are some sites that use an ordered list when marking up the progress meter. Hooray! Unfortunately, no text-only browser or screen reader would be able to describe the user’s current state given this markup.

<ol class=""progressmeter"">
	<li class=""one current"">shipping information</li>
	<li class=""two"">payment information</li>
	<li class=""three"">place your order</li>
</ol>

Without CSS enabled, the above is rendered as follows:



Progress at last

We all know that semantic markup makes for the best foundation, so we’ll start with the markup found above. In order to make the state information accessible, let’s add some additional text in paragraph and span elements.

<div class=""progressmeter"">
	<p>There are three steps in this checkout process.</p>
	<ol>
		<li class=""one""><span>Enter your</span> shipping information</li>
		<li class=""two""><span>Enter your</span> payment information</li>
		<li class=""three""><span>Review details and</span> place your order</li>
	</ol>
</div>

Add on some simple CSS to hide the paragraph and spans, and arrange the list items on a single line with a background image to represent the large number, and this is what you’ll get:

 
	There are three steps in this checkout process.
	
		Enter your shipping information
		Enter your payment information
		Review details and place your order
	
 

To display and describe a state as active, add the class “current” to one of the list items. Then change the hidden content such that it better describes the state to the user.

<div class=""progressmeter"">
	<p>There are three steps in this checkout process.</p>
	<ol>
		<li class=""one current""><span>You are currently entering your</span> shipping information</li>
		<li class=""two""><span>In the next step, you will enter your</span> payment information</li>
		<li class=""three""><span>In the last step, you will review the details and</span> place your order</li>
	</ol>
</div>

The end result is an attractive progress meter that gives much greater semantic and contextual information.

 
	There are three steps in this checkout process.
	
		You are currently entering your shipping information
		In the next step, you will enter your payment information
		In the last step, you will review the details and place your order
	
 

For example, the above example renders in a text-only browser as follows:

 
	There are three steps in this checkout process.
	
		You are currently entering your shipping information
		In the next step, you will enter your payment information
		In the last step, you will review the details and place your order
	
 

And the screen reader I use for testing announces the following:

 
	There are three steps in this checkout process. List of three items. You are currently entering your shipping information. In the next step, you will enter your payment information. In the last step, you will review the details and place your order. List end.
 

Here’s a sample code page that summarises this approach.

115,"Charm Clients, Win Pitches","Over the years I have picked up a number of sales techniques that have lead to us doing pretty well in the pitches we go for. Of course, up until now, these top secret practices have remained firmly locked in the company vault but now I am going to share them with you. They are cunningly hidden within the following paragraphs so I’m afraid you’re going to have to read the whole thing.

Ok, so where to start? I guess a good place would be getting invited to pitch for work in the first place.

Shameless self promotion

What not to do

You’re as keen as mustard to ‘sell’ what you do, but you have no idea as to the right approach. From personal experience (sometimes bitter!), the following methods are as useful as the proverbial chocolate teapot:


	Cold calling
	Advertising
	Bidding websites
	Sales people
	Networking events


Ok, I’m exaggerating; sometimes these things work. For example, cold calling can work if you have a story – a reason to call and introduce yourself other than “we do web design and you have a website”. “We do web design and we’ve just moved in next door to you” would be fine. 

Advertising can work if your offering is highly specialist. However, paying oodles of dollars a day to Google Ads to appear under the search term ‘web design’ is probably not the best use of your budget. 

Specialising is, in fact, probably a good way to go. Though it can feel counter intuitive in that you are not spreading yourself as widely as you might, you will eventually become an expert and therefore gain a reputation in your field. Specialism doesn’t necessarily have to be in a particular skillset or technology, it could just as easily be in a particular supply chain or across a market.

Target audience

‘Who to target?’ is the next question. If you’re starting out then do tap-up your family and friends. Anything that comes your way from them will almost certainly come with a strong recommendation. Also, there’s nothing wrong with calling clients you had dealings with in previous employment (though beware of any contractual terms that may prevent this). You are informing your previous clients that your situation has changed; leave it up to them to make any move towards working with you. After all, you’re simply asking to be included on the list of agencies invited to tender for any new work.

Look to target clients similar to those you have worked with previously. Again, you have a story – hopefully a good one!

So how do you reach these people?


	Mailing lists
	Forums
	Writing articles
	Conferences / Meetups
	Speaking opportunities
	Sharing Expertise


In essence: blog, chat, talk, enthuse, show off (a little)… share.

There are many ways you can do this. There’s the traditional portfolio, almost obligatory blog (regularly updated of course), podcast, ‘giveaways’ like Wordpress templates, CSS galleries and testimonials. Testimonials are your greatest friend. Always ask clients for quotes (write them and ask for their permission to use) and even better, film them talking about how great you are.

Finally, social networking sites can offer a way to reach your target audiences. You do have to be careful here though. You are looking to build a reputation by contributing value. Do not self promote or spam!

Writing proposals

Is it worth it?

Ok, so you have been invited to respond to a tender or brief in the form of a proposal. Good proposals take time to put together so you need to be sure that you are not wasting your time. There are two fundamental questions that you need to ask prior to getting started on your proposal:


	Can I deliver within the client’s timescales?
	Does the client’s budget match my price?


The timescales that clients set are often plucked from the air and a little explanation about how long projects usually take can be enough to change expectations with regard to delivery. However, if a deadline is set in stone ask yourself if you can realistically meet it. Agreeing to a deadline that you know you cannot meet just to win a project is a recipe for an unhappy client, no chance of repeat business and no chance of any recommendations to other potential clients.

Price is another thing altogether. So why do we need to know?

The first reason, and most honest reason, is that we don’t want to do a lot of unpaid pitch work when there is no chance that our price will be accepted. Who would? But this goes both ways – the client’s time is also being wasted. It may only be the time to read the proposal and reject it, but what if all the bids are too expensive? Then the client needs to go through the whole process again.

The second reason why we need to know budgets relates to what we would like to include in a proposal over what we need to include. For example, take usability testing. We always highly recommend that a client pays for at least one round of usability testing because it will definitely improve their new site – no question. But, not doing it doesn’t mean they’ll end up with an unusable turkey. It’s just more likely that any usability issues will crop up after launch.

I have found that the best way to discover a budget is to simply provide a ballpark total, usually accompanied by a list of ‘likely tasks for this type of project’, in an initial email or telephone response. Expect a lot of people to dismiss you out of hand. This is good. Don’t be tempted to ‘just go for it’ anyway because you like the client or work is short – you will regret it.

Others will say that the ballpark is ok. This is not as good as getting into a proper discussion about what priorities they might have but it does mean that you are not wasting your time and you do have a chance of winning the work. The only real risk with this approach is that you misinterpret the requirements and produce an inaccurate ballpark.

Finally, there is a less confrontational approach that I sometimes use that involves modular pricing. We break down our pricing into quite detailed tasks for all proposals but when I really do not have a clue about a client’s budget, I will often separate pricing into ‘core’ items and ‘optional’ items. This has proved to be a very effective method of presenting price.

What to include

So, what should go into a proposal? It does depend on the size of the piece of work. If it’s a quick update for an existing client then they don’t want to read through all your blurb about why they should choose to work with you – a simple email will suffice.

But, for a potential new client I would look to include the following:


	Your suitability
	Summary of tasks
	Timescales
	Project management methodology
	Pricing
	Testing methodology
	Hosting options
	Technologies
	Imagery
	References
	Financial information
	Biographies


However, probably the most important aspect of any proposal is that you respond fully to the brief. In other words, don’t ignore the bits that either don’t make sense to you or you think irrelevant. If something is questionable, cover it and explain why you don’t think it is something that warrants inclusion in the project.

Should you provide speculative designs? If the brief doesn’t ask for any, then certainly not. If it does, then speak to the client about why you don’t like to do speculative designs. Explain that any designs included as part of a proposal are created to impress the client and not the website’s target audience. Producing good web design is a partnership between client and agency. This can often impress and promote you as a professional. However, if they insist then you need to make a decision because not delivering any mock-ups will mean that all your other work will be a waste of time.

Walking away

As I have already mentioned, all of this takes a lot of work. So, when should you be prepared to walk away from a potential job? I have already covered unrealistic deadlines and insufficient budget but there are a couple of other reasons. Firstly, would this new client damage your reputation, particularly within current sectors you are working in? Secondly, can you work with this client? A difficult client will almost certainly lead to a loss-making project.

Perfect pitch

Requirements

If the original brief didn’t spell out what is expected of you at a presentation then make sure you ask beforehand. The critical element is how much time you have. It seems that panels are providing less and less time these days.

The usual formula is that you get an hour; half of which should be a presentation of your ideas followed by 30 minutes of questions. This isn’t that much time, particularly for a big project that covers all aspect of web design and production. Don’t be afraid to ask for more time, though it is very rare that you will be granted any.

Ask if there any areas that a) they particularly want you to cover and b) if there are any areas of your proposal that were weak.

Ask who will be attending. The main reason for this is to see if the decision maker(s) will be present but it’s also good to know if you’re presenting to 3 or 30 people.

Who should be there

Generally speaking, I think two is the ideal number. Though I have done many presentations on my own, I always feel having two people to bounce ideas around with and have a bit of banter with, works well. You are not only trying to sell your ideas and expertise but also yourselves. One of the main things in the panels minds will be – “can I work with these people?”

Having more than two people at a presentation often looks like you’re wheeling people out just to demonstrate that they exist.

What makes a client want to hire you?

In a nutshell: Confidence, Personality, Enthusiasm.

You can impart confidence by being well prepared and professional, providing examples and demonstrations and talking about your processes. You may find project management boring but pretty much every potential client will want to feel reassured that you manage your projects effectively.

As well as demonstrating that you know what you’re talking about, it is important to encourage, and be part of, discussion about the project. Be prepared to suggest and challenge and be willing to say “I don’t know”.

Also, no-one likes a show-off so don’t over promote yourself; encourage them to contact your existing clients.

What makes a client like you?

Engaging with a potential client is tricky and it’s probably the area where you need to be most on your toes and try to gauge the reaction of the client. We recommend the following:


	Encourage questions throughout
	Ask if you make sense – which encourages questions if you’re not getting any
	Humour – though don’t keep trying to be funny if you’re not getting any laughs!
	Be willing to go off track
	Read your audience
	Empathise with the process – chances are, most of the people in front of you would rather be doing something else
	Think about what you wear – this sounds daft but do you want to be seen as either the ‘stiff in the suit’ or the ‘scruffy art student’? Chances are neither character would get hired.


Differentiation

Sometimes, especially if you think you are an outsider, it’s worth taking a few risks. I remember my colleague Paul starting off a presentation once with the line (backed up on screen) – “Headscape is not a usability consultancy”. This was in response to the clients request to engage a usability consultancy. The thrust of Paul’s argument was that we are a lot more than that.

This really worked. We were the outside choice but they ended up hiring us. Basically, this differentiated us from the crowd. It showed that we are prepared to take risks and think, dare I say it, outside of the box.

Dealing with difficult characters 

How you react to tricky questioning is likely to be what determines whether you have a good or bad presentation. Here are a few of those characters that so often turn up in panels:

The techie – this is likely to be the situation where you need to say “I don’t know”. Don’t bluff as you are likely to dig yourself a great big embarrassment-filled hole. Promise to follow up with more information and make sure that you do so as quickly as possible after the pitch. 

The ‘hard man’ MD – this the guy who thinks it is his duty to throw ‘curve ball’ questions to see how you react. Focus on your track record (big name clients will impress this guy) and emphasise your processes.

The ‘no clue’ client – you need to take control and be the expert though you do need to explain the reasoning behind any suggestions you make. This person will be judging you on how much you are prepared to help them deliver the project.

The price negotiator – be prepared to discuss price but do not reduce your rate or the effort associated with your proposal. Fall back on modular pricing and try to reduce scope to come within budget. You may wish to offer a one-off discount to win a new piece of work but don’t get into detail at the pitch.

Don’t panic…

If you go into a presentation thinking ‘we must win this’ then, chances are, you won’t. Relax and be yourself. If you’re not hitting it off with the panel then so be it. You have to remember that quite often you will be making up the numbers in a tendering process. This is massively frustrating but, unfortunately, part of it. If it’s not going well, concentrate on what you are offering and try to demonstrate your professionalism rather than your personality. Finally, be on your toes, watch people’s reactions and pay attention to what they say and try to react accordingly.

So where are the secret techniques I hear you ask? Well, using the words ‘secret’ and ‘technique’ was probably a bit naughty. Most of this stuff is about being keen, using your brain and believing in yourself and what you are selling rather than following a strict set of rules.",2008,Marcus Lillington,marcuslillington,2008-12-09T00:00:00+00:00,https://24ways.org/2008/charm-clients-win-pitches/,business
102,Art Directing with Looking Room,"Using photographic composition techniques to start to art direct on the template-driven web.

Think back to last night. There you are, settled down in front of the TV, watching your favourite soap opera, with nice hot cup of tea in hand. Did you notice – whilst engrossed in the latest love-triangle – that the cameraman has worked very hard to support your eye’s natural movement on-screen? He’s carefully framed individual shots to create balance.

Think back to last week. There you were, sat with your mates watching the big match. Did you notice that the cameraman frames the shot to go with the direction of play? A player moving right will always be framed so that he is on the far left, with plenty of ‘room’ to run into.

Both of these cameramen use a technique called Looking Room, sometimes called Lead Room. Looking Room is the space between the subject (be it a football, or a face), and the edge of the screen. Specifically, Looking Room is the negative space on the side the subject is looking or moving. The great thing is, it’s not just limited to photography, film or television; we can use it in web design too.

Basic Framing

Before we get into Looking Room, and how it applies to web, we need to have a look at some basics of photographic composition.

Many web sites use imagery, or photographs, to enhance the content. But even with professionally shot photographs, without a basic understanding of framing or composition, you can damage how the image is perceived. 

A simple, easy way to make photographs more interesting is to fill the frame. 

Take this rather mundane photograph of a horse:



A typical point and click affair. But, we can work with this.

By closely cropping, and filling the frame, we can instantly change the mood of the shot.



I’ve also added Looking Room on the right of the horse. This is space that the horse would be walking into. It gives the photograph movement.

Subject, Space, and Movement

Generally speaking, a portrait photograph will have a subject and space around them. Visual interest in portrait photography can come from movement; how the eye moves around the shot. To get the eye moving, the photographer modifies the space around the subject.

Look at this portrait:



The photography has framed the subject on the right, allowing for whitespace, or Looking Room, in the direction the subject is looking. The framing of the subject (1), with the space to the left (2) – the Looking Room – creates movement, shown by the arrow (3).



Note the subject is not framed centrally (shown by the lighter dotted line).

If the photographer had framed the subject with equal space either side, the resulting composition is static, like our horse.



If the photographer framed the subject way over on the left, as she is looking that way, the resulting whitespace on the right leads a very uncomfortable composition.



The root of this discomfort is what the framing is telling our eye to do. The subject, looking to the left, suggests to us that we should do the same. However, the Looking Room on the right is telling our eye to occupy this space. The result is a confusing back and forth.

How Looking Room applies to the web

We can apply the same theory to laying out a web page or application. Taking the three same elements – Subject, Space, and resulting Movement – we can guide a user’s eye to the elements we need to. As designers, or content editors, framing photographs correctly can have a subtle but important effect on how a page is visually scanned. Take this example:



The BBC homepage uses great photography as a way of promoting content. Here, they have cropped the main photograph to guide the user’s eye into the content. 

By applying the same theory, the designer or content editor has applied considerable Looking Room (2) to the photograph to create balance with the overall page design, but also to create movement of the user’s eye toward the content (1)



If the image was flipped horizontally. The Looking Room is now on the right. The subject of the photograph is looking off the page, drawing the user’s eye away from the content. Once again, this results in a confusing back and forth as your eye fights its way over to the left of the page.



A little bit of Art Direction

Art Direction can be described as the act or process of managing the visual presentation of content. Art Direction is difficult to do on the web, because content and presentation are, more often than not, separated. But where there are images, and when we know the templates that those images will populate, we can go a little way to bridging the gap between content and presentation.

By understanding the value of framing and Looking Room, and the fact that it extends beyond just a good looking photograph, we can start to see photography playing more of an integral role in the communication of content. 

We won’t just be populating templates. We’ll be art directing.

98,Absolute Columns,"CSS layouts have come quite a long way since the dark ages of web publishing, with all sorts of creative applications of floats, negative margins, and even background images employed in order to give us that most basic building block, the column. As the title implies, we are indeed going to be discussing columns today—more to the point, a handy little application of absolute positioning that may be exactly what you’ve been looking for…

Care for a nightcap?

If you’ve been developing for the web for long enough, you may be familiar with this little children’s fable, passed down from wizened Shaolin monks sitting atop the great Mt. Geocities: “Once upon a time, multiple columns of the same height could be easily created using TABLES.” Now, though we’re all comfortably seated on the standards train (and let’s be honest: even if you like to think you’ve fallen off, if you’ve given up using tables for layout, rest assured your sleeper car is still reserved), this particular—and as page layout goes, quite basic—trick is still a thorn in our CSSides compared to the ease of achieving the same effect using said Tables of Evil™.

See, the orange juice masks the flavor…

Creative solutions such as Dan Cederholm’s  Faux Columns do a good job of making it appear as though adjacent columns maintain equal height as content expands, using a background image to fill the space that the columns cannot.

Now, the Holy Grail of CSS columns behaving exactly how they would as table cells—or more to the point, as columns—still eludes us (cough CSS3 Multi-column layout module cough), but sometimes you just need, for example, a secondary column (say, a sidebar) to match the height of a primary column, without involving the creation of images. This is where a little absolute positioning can save you time, while possibly giving your layout a little more flexibility.

Shaken, not stirred

You’re probably familiar by now with the concept of Making the Absolute, Relative as set forth long ago by Doug Bowman, but let’s quickly review just in case: an element set to position:absolute will position itself relative to its nearest ancestor set to position:relative, rather than the browser window (see Figure 1).

 Figure 1.

However, what you may not know is that we can anchor more than two sides of an absolutely positioned element. Yes, that’s right, all four sides (top, right, bottom, left) can be set, though in this example we’re only going to require the services of three sides (see Figure 2 for the end result).

 Figure 2.

Trust me, this will make you feel better

Our requirements are essentially the same as the standard “absolute-relative” trick—a container <div> set to position:relative, and our sidebar <div> set to position:absolute — plus another <div> that will serve as our main content column. We’ll also add a few other common layout elements (wrapper, header, and footer) so our example markup looks more like a real layout and less like a test case:

<div id=""wrapper"">
	<div id=""header"">
		<h2>#header</h2>
	</div>
	<div id=""container"">
		<div id=""column-left"">
			<h2>#left</h2>
			<p>Lorem ipsum dolor sit amet…</p>
		</div>
		<div id=""column-right"">
			<h2>#right</h2>
		</div>
	</div>
	<div id=""footer"">
		<h2>#footer</h2>
	</div>
</div>

In this example, our main column (#column-left) is only being given a width to fit within the context of the layout, and is otherwise untouched (though we’re using pixels here, this trick will of course work with fluid layouts as well), and our right keeping our styles nice and minimal:

#container {
	position: relative;
}
#column-left {
	width: 480px;
}
#column-right {
	position: absolute;
	top: 10px;
	right: 10px;
	bottom: 10px;
	width: 250px;
}

The trick is a simple one: the #container <div> will expand vertically to fit the content within #column-left. By telling our sidebar <div> (#column-right) to attach itself not only to the top and right edges of #container, but also to the bottom, it too will expand and contract to match the height of the left column (duplicate the “lorem ipsum” paragraph a few times to see it in action).

 Figure 3.

On the rocks

“But wait!” I hear you exclaim, “when the right column has more content than the left column, it doesn’t expand! My text runneth over!” Sure enough, that’s exactly what happens, and what’s more, it’s supposed to: Absolutely positioned elements do exactly what you tell them to do, and unfortunately aren’t very good at thinking outside the box (get it? sigh…). 

However, this needn’t get your spirits down, because there’s an easy way to address the issue: by adding overflow:auto to #column-right, a scrollbar will automatically appear if and when needed:

#column-right {
	position: absolute;
	top: 10px;
	right: 10px;
	bottom: 10px;
	width: 250px;
	overflow: auto;
}

While this may limit the trick’s usefulness to situations where the primary column will almost always have more content than the secondary column—or where the secondary column’s content can scroll with wild abandon—a little prior planning will make it easy to incorporate into your designs.

Driving us to drink

It just wouldn’t be right to have a friendly, festive holiday tutorial without inviting IE6, though in this particular instance there will be no shaming that old browser into admitting it has a problem, nor an intervention and subsequent 12-step program. That’s right my friends, this tutorial has abstained from IE6-abuse now for 30 days, thanks to the wizard Dean Edwards and his amazingly talented IE7 Javascript library.

Simply drop the Conditional Comment and <script> element into the <head> of your document, along with one tiny CSS hack that only IE6 (and below) will ever see, and that browser will be back on the straight and narrow:

<!--[if lt IE 7]>
<script src=""http://ie7-js.googlecode.com/svn/version/2.0(beta3)/IE7.js"" type=""text/javascript""></script>
<style type=""text/css"" media=""screen"">

		zoom:1; /* helps fix IE6 by initiating hasLayout */
	}
</style>

Like all follies this is an embellishment — a bit of web typography fun. It’s similar to the masthead text at my place, but it’s also a hyperlink. Unlike the architectural follies of the past, no child labour was used to fund or build it, just some HTML flavoured with CSS, and a heavy dose of Times New Roman. Why Times New Roman, you ask? Well, after a few wasted hours experimenting with heaps of typefaces, seeking an elusive consistency of positioning and rendering across platforms, it proved to be the most consistent. Who’d‘a thought? To make things more interesting, I wanted to use a traditional scale and make the whole thing elastic by using relative lengths that would react to a person’s font size. So, to the meat of this festive frippery:

There are three things we rely on to create this indulgence:


	Descendant selectors
	Absolute positioning
	Inheritance


HTML & Descendant Selectors

The markup for the folly might seem complex at first glance. To semantics pedants and purists it may seem outrageous. If that’s you, read on at your peril! Here it is with lots of whitespace:

<div id=""type"">
<h1>
  <a href=""/"">
    <em>2
      <span>4 
        <span>w
          <span>a
            <span>y
              <span>s</span>
            </span>
          </span>
        </span>
      </span>
    </em> 
    <strong>to 
      <span>i
        <span>m
          <span>pre
            <span>s
              <span>s 
                <span>your 
                  <span>friends</span>
                </span>
              </span>
            </span>
          </span>
        </span>
      </span>
    </strong>	
  </a>
</h1>
</div>

Why so much markup? Well, we want to individually style many of the glyphs. By nesting the elements, we can pick out the bits we need as descendant selectors.

To retain a smidgen of semantics, the text is wrapped in <h1> and <a> elements. The two phrases, “24 ways” and “to impress your friends” are wrapped in <em> and <strong> tags, respectively. Within those loving arms, their descendant <span>s cascade invisibly, making a right mess of our source, but ready to be picked out in our CSS rules.

So, to select the “2” from the example we can simply write, #type h1 em{ }. Of course, that selects everything within the <em> tags, but as we drill down the document tree, selecting other glyphs, any property / value styles can be reset or changed as required.

Pixels Versus Ems

Before we get stuck into the CSS, I should say that the goal here is to have everything expressed in relative “em” lengths. However, when I’m starting out, I use pixels for all values, and only convert them to ems after I’ve finished. It saves re-calculating the em length for every change I make as the folly evolves, but still makes the final result elastic, without relying on browser zoom.

To skip ahead, see the complete CSS.

Absolutely Positioned Glyphs

If a parent element has position: relative, or position: absolute applied to it, all children of that parent can be positioned absolutely relative to it. (See Dave Shea’s excellent introduction to this.) That’s exactly how the folly is achieved. As the parent, #type also has a font-size of 16px set, a width and height, and some basic style with a background and border:

#type{
	font-size: 16px;
	text-align: left;
	background: #e8e9de;
	border: 0.375em solid #fff;
	width: 22.5em;
	height: 13.125em;
	position: relative;
}

The h1 is also given a default style with a font-size of 132px in ems relative to the parent font-size of 16px:

#type h1{
	font-family: ""Times New Roman"", serif;
	font-size: 8.25em; /* 132px */
	line-height: 1em;
	font-weight: 400;
	margin: 0;
	padding: 0;
}

To get the em value, we divide the required size in pixels by the actual parent font-size in pixels

132 ÷ 16 = 8.25

We also give the descendants of the h1 some default properties. The line height, style and weight are normalised, they are positioned absolutely relative to #type, and a border and padding is applied:

#type h1 em,
#type h1 strong,
#type h1 span{
	line-height: 1em;
	font-style: normal;
	font-weight: 400;
	position: absolute;
	padding: 0.1em;
	border: 1px solid transparent;
}

The padding ensures that some browsers don’t forget about parts of a glyph that are drawn outside of their invisible container. When this happens, IE will trim the glyph, cutting off parts of descenders, for example. The border is there to make sure the glyphs have layout. Without this, positioning can be problematic. IE6 will not respect the transparent border colour — it uses the actual text colour — but in all other respects renders the example. You can hack around it, but it seemed unnecessary for this example.

Once these defaults are established, the rest is trial and error. As a quick example, the numeral “2” is first to be positioned:

#type h1 a em{
	font-size: 0.727em; /* (2) 96px */
	left: 0.667em;
	top: 0;
}

Every element of the folly is positioned in exactly the same way as you can see in the complete CSS. When converting pixels to ems, the font-size is set first. Then, because we know what that is, we calculate the equivalent x- and y-position accordingly.

Inheritance

CSS inheritance gave me a headache a long time ago when I first encountered it. After the penny dropped I came to experience something disturbingly close to affection for this characteristic. What it basically means is that children inherit the characteristics of their parents. For example:


	We gave #type a font-size of 16px.
	For #type h1 we changed it by setting font-size: 8.25em;. Than means that #type h1 now has a computed font-size of 8.25 × 16px = 132px.
	Now, all children of #type h1 in the document tree will inherit a font-size of 132px unless we explicitly change it as we did for #type h1 a em.


The “2” in the example — selected with #type h1 a em — is set at 96px with left and top positioning calculated relatively to that. So, the left position of 0.667em is 0.667 × 96 = 64px, approximately (three decimal points in em lengths don’t always give exact pixel equivalents).

One way to look at inheritance is as a cascade of dependancy: In our example, the computed font size of any given element depends on that of the parent, and the absolute x- and y-position depends on the computed font size of the element itself.

Link Colours

The same descendant selectors we use to set and position the type are also used to apply the colour by combining them with pseudo-selectors like :focus and :hover. Because the descendant selectors are available to us, we can pretty much pick out any glyph we like. First, we need to disable the underline:

#type h1 a:link,
#type h1 a:visited{
	text-decoration: none;
}

In our example, the “24” has a unique default state (colour):

#type h1 a:link em,
#type h1 a:visited em{
	color: #624;
}

The rest of the “Ways” text has a different colour, which it shares with the large “s” in “impress”:

#type h1 a:link em span span,
#type h1 a:visited em span span,
#type h1 a:link strong span span span span,
#type h1 a:visited strong span span span span{
	color: #b32720;
}

“24” changes on :focus, :hover and :active. Critically though, the whole of the “24 Ways” text, and the large “s” in “impress” all have the same style in this instance:

#type h1 a:focus em,
#type h1 a:hover em,
#type h1 a:active em,
#type h1 a:focus em span span,
#type h1 a:hover em span span,
#type h1 a:active em span span,
#type h1 a:focus strong span span span span,
#type h1 a:hover strong span span span span,
#type h1 a:active strong span span span span{
	color: #804;
}

If a descendant selector has a :link and :visited state set as a pseudo element, it needs to also have the corresponding :focus, :hover and :active states set.

A Final Note About Web Typography

From grids to basic leading to web fonts, and even absolute positioning, there’s a wealth of things we can do to treat type on the Web with love and respect. However, experiments like this can highlight the vagaries of rasterisation and rendering that limit our ability to achieve truly subtle and refined results. At the operating system level, the differences in type rendering are extreme, and even between sequential iterations in Windows — from Standard to ClearType — they can be daunting. Add to that huge variations in screen quality, and even the paper we print our type onto has many potential variations. Compare our example in Safari 3.2.1 / OS X 10.5.5 (left) and IE7 / Win XP (right). Both rendered on a 23” Apple Cinema HD (LCD):



Browser developers continue to make great strides. However, those of us who set type on the Web need more consistency and quality if we want to avoid technologies like Flash and evolve web typography. Although web typography is inevitably — and mistakenly — compared unfavourably to print, it has the potential to achieve the same refinement in a different way. Perhaps one day, the glyphs of our favourite faces, so carefully crafted, kerned and hinted for the screen, will be rendered with the same precision with which they were drawn by type designers and styled by web designers. That would be my wish for the new year. Happy holidays!",2008,Jon Tan,jontan,2008-12-17T00:00:00+00:00,https://24ways.org/2008/a-festive-type-folly/,design
99,A Christmas hCard From Me To You,"So apparently Christmas is coming. And what is Christmas all about? Well, cleaning out your address book, of course! What better time to go through your contacts, making sure everyone’s details are up date and that you’ve deleted all those nasty clients who never paid on time?

It’s also a good time to make sure your current clients and colleagues have your most up-to-date details, so instead of filling up their inboxes with e-cards, why not send them something useful? Something like a… vCard! (See what I did there?)

Just in case you’ve been working in a magical toy factory in the upper reaches of Scandinavia for the last few years, I’m going to tell you that now would also be the perfect time to get into microformats. Using the hCard format, we’ll build a very simple web page and markup our contact details in such a way that they’ll be understood by microformats plugins, like Operator or Tails for Firefox, or the cross-browser Microformats Bookmarklet.

Oh, and because Christmas is all about dressing up and being silly, we’ll make the whole thing look nice and have a bit of fun with some CSS3 progressive enhancement. 

If you can’t wait to see what we end up with, you can preview it here.



Step 1: Contact Details

First, let’s decide what details we want to put on the page. I’d put my full name, my email address, my phone number, and my postal address, but I’d rather not get surprise visits from strangers when I’m fannying about with my baubles, so I’m going to use Father Christmas instead (that’s Santa to you Yanks).

Father Christmas
fatherchristmas@elliotjaystocks.com
25 Laughingallthe Way
Snow Falls
Lapland
Finland
010 60 58 000

Step 2: hCard Creator

Now I’m not sure about you, but I rather like getting the magical robot pixies to do the work for me, so head on over to the hCard Creator and put those pixies to work! Pop in your details and they’ll give you some nice microformatted HTML in turn.



<div id=""hcard-Father-Christmas"" class=""vcard"">
	<a class=""url fn"" href=""http://elliotjaystocks.com/fatherchristmas"">Father Christmas</a>
	<a class=""email"" href=""mailto:fatherchristmas@elliotjaystocks.com""> fatherchristmas@elliotjaystocks.com</a>
	<div class=""adr"">
	<div class=""street-address"">25 Laughingallthe Way</div>
	<span class=""locality"">Snow Falls</span>
	, 
	<span class=""region"">Lapland</span>
	, 
	<span class=""postal-code"">FI-00101</span>
	<span class=""country-name"">Finland</span>
</div>
<div class=""tel"">010 60 58 000</div>
	<p style=""font-size:smaller;"">This <a href=""http://microformats.org/wiki/hcard"">hCard</a> created with the <a href=""http://microformats.org/code/hcard/creator"">hCard creator</a>.</p>
</div>

Step 3: Editing The Code

One of the great things about microformats is that you can use pretty much whichever HTML tags you want, so just because the hCard Creator Fairies say something should be wrapped in a <span> doesn’t mean you can’t change it to a <blink>. Actually, no, don’t do that. That’s not even excusable at Christmas.

I personally have a penchant for marking up each line of an address inside a <li> tag, where the parent url retains the class of adr. As long as you keep the class names the same, you’ll be fine.

<div id=""hcard-Father-Christmas"" class=""vcard"">
	<h1><a class=""url fn"" href=""http://elliotjaystocks.com/fatherchristmas"">Father Christmas </a></h1>
	<a class=""email"" href=""mailto:fatherchristmas@elliotjaystocks.com?subject=Here, have some Christmas cheer!"">fatherchristmas@elliotjaystocks.com</a>
	<ul class=""adr"">
		<li class=""street-address"">25 Laughingallthe Way</li>
		<li class=""locality"">Snow Falls</li>
		<li class=""region"">Lapland</li>
		<li class=""postal-code"">FI-00101</li>
		<li class=""country-name"">Finland</li>
	</ul>
	<span class=""tel"">010 60 58 000</span>
</div>

Step 4: Testing The Microformats

With our microformats in place, now would be a good time to test that they’re working before we start making things look pretty. If you’re on Firefox, you can install the Operator or Tails extensions, but if you’re on another browser, just add the Microformats Bookmarklet. Regardless of your choice, the results is the same: if you’ve code microformatted content on a web page, one of these bad boys should pick it up for you and allow you to export the contact info. Give it a try and you should see father Christmas appearing in your address book of choice. Now you’ll never forget where to send those Christmas lists!



Step 5: Some Extra Markup

One of the first things we’re going to do is put a photo of Father Christmas on the hCard. We’ll be using CSS to apply a background image to a div, so we’ll be needing an extra div with a class name of “photo”. In turn, we’ll wrap the text-based elements of our hCard inside a div cunningly called “text”. Unfortunately, because of the float technique we’ll be using, we’ll have to use one of those nasty float-clearing techniques. I shall call this “christmas-cheer”, since that is what its presence will inevitably bring, of course.

Oh, and let’s add a bit of text to give the page context, too:

<p>Send your Christmas lists my way...</p>
<div id=""hcard-Father-Christmas"" class=""vcard"">
	<div class=""text"">
		<h1><a class=""url fn"" href=""http://elliotjaystocks.com/fatherchristmas"">Father Christmas </a></h1>
		<a class=""email"" href=""mailto:fatherchristmas@elliotjaystocks.com?subject=Here, have some Christmas cheer!"">fatherchristmas@elliotjaystocks.com</a>

			<li class=""region"">Lapland</li>
			<li class=""postal-code"">FI-00101</li>
			<li class=""country-name"">Finland</li>
		</ul>
		<span class=""tel"">010 60 58 000</span>
	</div>
	<div class=""photo""></div>
	<br class=""christmas-cheer"" />
</div>
<div class=""credits"">

</div>

Step 6: Some Christmas Sparkle

So far, our hCard-housing web page is slightly less than inspiring, isn’t it? It’s time to add a bit of CSS. There’s nothing particularly radical going on here; just a simple layout, some basic typographic treatment, and the placement of the Father Christmas photo. I’d usually use a more thorough CSS reset like the one found in the YUI or Eric Meyer’s, but for this basic page, the simple * solution will do.

Check out the step 6 demo to see our basic styles in place.

From this…



… to this:



Step 7: Fun With imagery

Now it’s time to introduce a repeating background image to the <body> element. This will seamlessly repeat for as wide as the browser window becomes.

But that’s fairly straightforward. How about having some fun with the Father Christmas image? If you look at the image file itself, you’ll see that it’s twice as wide as the area we can see and contains a ‘hidden’ photo of our rather camp St. Nick.



As a light-hearted visual… er… ‘treat’ for users who move their mouse over the image, we move the position of the background image on the “photo” div. Check out the step 7 demo to see it working.

Step 8: Progressive Enhancement

Finally, this fun little project is a great opportunity for us to mess around with some advanced CSS features (some from the CSS3 spec) that we rarely get to use on client projects. (Don’t forget: no Christmas pressies for clients who want you to support IE6!)

Here are the rules we’re using to give some browsers a superior viewing experience:


	@font-face allows us to use Jos Buivenga’s free font ‘Fertigo Pro’ on all text;
	text-shadow adds a little emphasis on the opening paragraph;
	body > p:first-child causes only the first paragraph to receive this treatment;
	border-radius created rounded corners on our main div and the links within it;
	and webkit-transition allows us to gently fade in between the default and hover states of those links.


And with that, we’re done! You can see the results here. It’s time to customise the page to your liking, upload it to your site, and send out the URL. And do it quickly, because I’m sure you’ve got some last-minute Christmas shopping to finish off!",2008,Elliot Jay Stocks,elliotjaystocks,2008-12-10T00:00:00+00:00,https://24ways.org/2008/a-christmas-hcard-from-me-to-you/,code
168,Unobtrusively Mapping Microformats with jQuery,"Microformats are everywhere. You can’t shake an electronic stick these days without accidentally poking a microformat-enabled site, and many developers use microformats as a matter of course. And why not? After all, why invent your own class names when you can re-use pre-defined ones that give your site extra functionality for free?

Nevertheless, while it’s good to know that users of tools such as Tails and Operator will derive added value from your shiny semantics, it’s nice to be able to reuse that effort in your own code.

We’re going to build a map of some of my favourite restaurants in Brighton. Fitting with the principles of unobtrusive JavaScript, we’ll start with a semantically marked up list of restaurants, then use JavaScript to add the map, look up the restaurant locations and plot them as markers.

We’ll be using a couple of powerful tools. The first is jQuery, a JavaScript library that is ideally suited for unobtrusive scripting. jQuery allows us to manipulate elements on the page based on their CSS selector, which makes it easy to extract information from microformats.

The second is Mapstraction, introduced here by Andrew Turner a few days ago. We’ll be using Google Maps in the background, but Mapstraction makes it easy to change to a different provider if we want to later.

Getting Started

We’ll start off with a simple collection of microformatted restaurant details, representing my seven favourite restaurants in Brighton. The full, unstyled list can be seen in restaurants-plain.html. Each restaurant listing looks like this:

<li class=""vcard"">
	<h3><a class=""fn org url"" href=""http://www.riddleandfinns.co.uk/"">Riddle & Finns</a></h3>
	<div class=""adr"">
		<p class=""street-address"">12b Meeting House Lane</p>
		<p><span class=""locality"">Brighton</span>, <abbr class=""country-name"" title=""United Kingdom"">UK</abbr></p>
		<p class=""postal-code"">BN1 1HB</p>
	</div>
	<p>Telephone: <span class=""tel"">+44 (0)1273 323 008</span></p>
	<p>E-mail: <a href=""mailto:info@riddleandfinns.co.uk"" class=""email"">info@riddleandfinns.co.uk</a></p>
</li>

Since we’re dealing with a list of restaurants, each hCard is marked up inside a list item. Each restaurant is an organisation; we signify this by placing the classes fn and org on the element surrounding the restaurant’s name (according to the hCard spec, setting both fn and org to the same value signifies that the hCard represents an organisation rather than a person).

The address information itself is contained within a div of class adr. Note that the HTML <address> element is not suitable here for two reasons: firstly, it is intended to mark up contact details for the current document rather than generic addresses; secondly, address is an inline element and as such cannot contain the paragraphs elements used here for the address information.

A nice thing about microformats is that they provide us with automatic hooks for our styling. For the moment we’ll just tidy up the whitespace a bit; for more advanced style tips consult John Allsop’s guide from 24 ways 2006.

.vcard p {
	margin: 0;
}
.adr {
	margin-bottom: 0.5em;
}

To plot the restaurants on a map we’ll need latitude and longitude for each one. We can find this out from their address using geocoding. Most mapping APIs include support for geocoding, which means we can pass the API an address and get back a latitude/longitude point. Mapstraction provides an abstraction layer around these APIs which can be included using the following script tag:

<script type=""text/javascript"" src=""http://mapstraction.com/src/mapstraction-geocode.js""></script>

While we’re at it, let’s pull in the other external scripts we’ll be using:

<script type=""text/javascript"" src=""jquery-1.2.1.js""></script>
<script src=""http://maps.google.com/maps?file=api&v=2&key=YOUR_KEY"" type=""text/javascript""></script>
<script type=""text/javascript"" src=""http://mapstraction.com/src/mapstraction.js""></script>
<script type=""text/javascript"" src=""http://mapstraction.com/src/mapstraction-geocode.js""></script>

That’s everything set up: let’s write some JavaScript!

In jQuery, almost every operation starts with a call to the jQuery function. The function simulates method overloading to behave in different ways depending on the arguments passed to it. When writing unobtrusive JavaScript it’s important to set up code to execute when the page has loaded to the point that the DOM is available to be manipulated. To do this with jQuery, pass a callback function to the jQuery function itself:

jQuery(function() {
	// This code will be executed when the DOM is ready
});

Initialising the map

The first thing we need to do is initialise our map. Mapstraction needs a div with an explicit width, height and ID to show it where to put the map. Our document doesn’t currently include this markup, but we can insert it with a single line of jQuery code:

jQuery(function() {
	// First create a div to host the map
	var themap = jQuery('<div id=""themap""></div>').css({
		'width': '90%',
		'height': '400px'
	}).insertBefore('ul.restaurants');
});

While this is technically just a single line of JavaScript (with line-breaks added for readability) it’s actually doing quite a lot of work. Let’s break it down in to steps:

var themap = jQuery('<div id=""themap""></div>')

Here’s jQuery’s method overloading in action: if you pass it a string that starts with a < it assumes that you wish to create a new HTML element. This provides us with a handy shortcut for the more verbose DOM equivalent:

var themap = document.createElement('div');
themap.id = 'themap';

Next we want to apply some CSS rules to the element. jQuery supports chaining, which means we can continue to call methods on the object returned by jQuery or any of its methods:

var themap = jQuery('<div id=""themap""></div>').css({
	'width': '90%',
	'height': '400px'
})

Finally, we need to insert our new HTML element in to the page. jQuery provides a number of methods for element insertion, but in this case we want to position it directly before the <ul> we are using to contain our restaurants. jQuery’s insertBefore() method takes a CSS selector indicating an element already on the page and places the current jQuery selection directly before that element in the DOM.

var themap = jQuery('<div id=""themap""></div>').css({
	'width': '90%',
	'height': '400px'
}).insertBefore('ul.restaurants');

Finally, we need to initialise the map itself using Mapstraction. The Mapstraction constructor takes two arguments: the first is the ID of the element used to position the map; the second is the mapping provider to use (in this case google ):

// Initialise the map
var mapstraction = new Mapstraction('themap','google');

We want the map to appear centred on Brighton, so we’ll need to know the correct co-ordinates. We can use www.getlatlon.com to find both the co-ordinates and the initial map zoom level.

// Show map centred on Brighton
mapstraction.setCenterAndZoom(
	new LatLonPoint(50.82423734980143, -0.14007568359375),
	15 // Zoom level appropriate for Brighton city centre
);

We also want controls on the map to allow the user to zoom in and out and toggle between map and satellite view.

mapstraction.addControls({
	zoom: 'large',
	map_type: true
});

Adding the markers

It’s finally time to parse some microformats. Since we’re using hCard, the information we want is wrapped in elements with the class vcard. We can use jQuery’s CSS selector support to find them:

var vcards = jQuery('.vcard');

Now that we’ve found them, we need to create a marker for each one in turn. Rather than using a regular JavaScript for loop, we can instead use jQuery’s each() method to execute a function against each of the hCards.

jQuery('.vcard').each(function() {
	// Do something with the hCard
});

Within the callback function, this is set to the current DOM element (in our case, the list item). If we want to call the magic jQuery methods on it we’ll need to wrap it in another call to jQuery:

jQuery('.vcard').each(function() {
	var hcard = jQuery(this);
});

The Google maps geocoder seems to work best if you pass it the street address and a postcode. We can extract these using CSS selectors: this time, we’ll use jQuery’s find() method which searches within the current jQuery selection:

var streetaddress = hcard.find('.street-address').text();
var postcode = hcard.find('.postal-code').text();

The text() method extracts the text contents of the selected node, minus any HTML markup.

We’ve got the address; now we need to geocode it. Mapstraction’s geocoding API requires us to first construct a MapstractionGeocoder, then use the geocode() method to pass it an address. Here’s the code outline:

var geocoder = new MapstractionGeocoder(onComplete, 'google');
geocoder.geocode({'address': 'the address goes here');

The onComplete function is executed when the geocoding operation has been completed, and will be passed an object with the resulting point on the map. We just want to create a marker for the point:

var geocoder = new MapstractionGeocoder(function(result) {
	var marker = new Marker(result.point);
	mapstraction.addMarker(marker);
}, 'google');   

For our purposes, joining the street address and postcode with a comma to create the address should suffice:

geocoder.geocode({'address': streetaddress + ', ' + postcode});   

There’s one last step: when the marker is clicked, we want to display details of the restaurant. We can do this with an info bubble, which can be configured by passing in a string of HTML. We’ll construct that HTML using jQuery’s html() method on our hcard object, which extracts the HTML contained within that DOM node as a string.

var marker = new Marker(result.point);
marker.setInfoBubble(
	'<div class=""bubble"">' + hcard.html() + '</div>'
);
mapstraction.addMarker(marker);

We’ve wrapped the bubble in a div with class bubble to make it easier to style. Google Maps can behave strangely if you don’t provide an explicit width for your info bubbles, so we’ll add that to our CSS now:

.bubble {
	width: 300px;
}

That’s everything we need: let’s combine our code together:

jQuery(function() {
	// First create a div to host the map
	var themap = jQuery('<div id=""themap""></div>').css({
		'width': '90%',
		'height': '400px'
	}).insertBefore('ul.restaurants');
	// Now initialise the map
	var mapstraction = new Mapstraction('themap','google');
	mapstraction.addControls({
		zoom: 'large',
		map_type: true
	});
	// Show map centred on Brighton
	mapstraction.setCenterAndZoom(
		new LatLonPoint(50.82423734980143, -0.14007568359375),
		15 // Zoom level appropriate for Brighton city centre
	);
	// Geocode each hcard and add a marker
	jQuery('.vcard').each(function() {
		var hcard = jQuery(this);
		var streetaddress = hcard.find('.street-address').text();
		var postcode = hcard.find('.postal-code').text();
		var geocoder = new MapstractionGeocoder(function(result) {
			var marker = new Marker(result.point);
			marker.setInfoBubble(
				'<div class=""bubble"">' + hcard.html() + '</div>'
			);
			mapstraction.addMarker(marker);
		}, 'google');	 
		geocoder.geocode({'address': streetaddress + ', ' + postcode});
	});
});

Here’s the finished code.

There’s one last shortcut we can add: jQuery provides the $ symbol as an alias for jQuery. We could just go through our code and replace every call to jQuery() with a call to $(), but this would cause incompatibilities if we ever attempted to use our script on a page that also includes the Prototype library. A more robust approach is to start our code with the following:

jQuery(function($) {
	// Within this function, $ now refers to jQuery
	// ...
});

jQuery cleverly passes itself as the first argument to any function registered to the DOM ready event, which means we can assign a local $ variable shortcut without affecting the $ symbol in the global scope. This makes it easy to use jQuery with other libraries.

Limitations of Geocoding

You may have noticed a discrepancy creep in to the last example: whereas my original list included seven restaurants, the geocoding example only shows five. This is because the Google Maps geocoder incorporates a rate limit: more than five lookups in a second and it starts returning error messages instead of regular results.

In addition to this problem, geocoding itself is an inexact science: while UK postcodes generally get you down to the correct street, figuring out the exact point on the street from the provided address usually isn’t too accurate (although Google do a pretty good job).

Finally, there’s the performance overhead. We’re making five geocoding requests to Google for every page served, even though the restaurants themselves aren’t likely to change location any time soon. Surely there’s a better way of doing this?

Microformats to the rescue (again)! The geo microformat suggests simple classes for including latitude and longitude information in a page. We can add specific points for each restaurant using the following markup:

<li class=""vcard"">
	<h3 class=""fn org"">E-Kagen</h3>
	<div class=""adr"">
		<p class=""street-address"">22-23 Sydney Street</p>
		<p><span class=""locality"">Brighton</span>, <abbr class=""country-name"" title=""United Kingdom"">UK</abbr></p>
		<p class=""postal-code"">BN1 4EN</p>
	</div>
	<p>Telephone: <span class=""tel"">+44 (0)1273 687 068</span></p>
	<p class=""geo"">Lat/Lon: 
		<span class=""latitude"">50.827917</span>, 
		<span class=""longitude"">-0.137764</span>
	</p>
</li>

As before, I used www.getlatlon.com to find the exact locations – I find satellite view is particularly useful for locating individual buildings.

Latitudes and longitudes are great for machines but not so useful for human beings. We could hide them entirely with display: none, but I prefer to merely de-emphasise them (someone might want them for their GPS unit):

.vcard .geo {
	margin-top: 0.5em;
	font-size: 0.85em;
	color: #ccc;
}

It’s probably a good idea to hide them completely when they’re displayed inside an info bubble:

.bubble .geo {
	display: none;
}

We can extract the co-ordinates in the same way we extracted the address. Since we’re no longer geocoding anything our code becomes a lot simpler:

$('.vcard').each(function() {
	var hcard = $(this);
	var latitude = hcard.find('.geo .latitude').text();
	var longitude = hcard.find('.geo .longitude').text();
	var marker = new Marker(new LatLonPoint(latitude, longitude));
	marker.setInfoBubble(
		'<div class=""bubble"">' + hcard.html() + '</div>'
	);
	mapstraction.addMarker(marker);
});

And here’s the finished geo example.

149,Underpants Over My Trousers,"With Christmas approaching faster than a speeding bullet, this is the perfect time for you to think about that last minute present to buy for the web geek in your life. If you’re stuck for ideas for that special someone, forget about that svelte iPhone case carved from solid mahogany and head instead to your nearest comic-book shop and pick up a selection of comics or graphic novels. (I’ll be using some of my personal favourite comic books as examples throughout). 

Trust me, whether your nearest and dearest has been reading comics for a while or has never peered inside this four-colour world, they’ll thank-you for it.

Aside from indulging their superhero fantasies, comic books can provide web designers with a rich vein of inspiring ideas and material to help them create shirt button popping, trouser bursting work for the web. I know from my own personal experience, that looking at aspects of comic book design, layout and conventions and thinking about the ways that they can inform web design has taken my design work in often-unexpected directions. 

There are far too many fascinating facets of comic book design that provide web designers with inspiration to cover in the time that it takes to pull your underpants over your trousers. So I’m going to concentrate on one muscle bound aspect of comic design, one that will make you think differently about how you lay out the content of your pages in panels. 

A suitcase full of Kryptonite

Now, to the uninitiated onlooker, the panels of a comic book may appear to perform a similar function to still frames from a movie. But inside the pages of a comic, panels must work harder to help the reader understand the timing of a story. It is this method for conveying narrative timing to a reader that I believe can be highly useful to designers who work on the web as timing, drama and suspense are as important in the web world as they are in worlds occupied by costumed crime fighters and superheroes.

I’d like you to start by closing your eyes and thinking about your own process for laying out panels of content on a page. OK, you’ll actually be better off with your eyes open if you’re going to carry on reading.

I’ll bet you a suitcase full of Kryptonite that you often, if not always, structure your page layouts, and decide on the dimensions of those panels according to either:


	The base grid that you are working to
	The Golden Ratio or another mathematical schema


More likely, I bet that you decide on the size and the number of your panels based on the amount of content that will be going into them. From today, I’d like you to think about taking a different approach. This approach not only addresses horizontal and vertical space, but also adds the dimension of time to your designs.

Slowing down the action

A comic book panel not only acts as a container for its content but also indicates to a reader how much time passes within the panel and as a result, how much time the reader should focus their attention on that one panel. 

Smaller panels create swift eye movement and shorter bursts of attention. Larger panels give the perception of more time elapsing in the story and subconsciously demands that a reader devotes more time to focus on it. 

Concrete by Paul Chadwick (Dark Horse Comics)

This use of panel dimensions to control timing can also be useful for web designers in designing the reading/user experience. Imagine a page full of information about a product or service. You’ll naturally want the reader to focus for longer on the key benefits of your offering rather than perhaps its technical specifications.

Now take a look at this spread of pages from Watchmen by Alan Moore and Dave Gibbons.

Watchmen by Alan Moore and Dave Gibbons (Diamond Comic Distributors 2004)

Throughout this series of (originally) twelve editions, artist Dave Gibbons stuck rigidly to his 3×3 panels per page design and deviated from it only for dramatic moments within the narrative. 

In particular during the last few pages of chapter eleven, Gibbons adds weight to the impending doom by slowing down the action by using larger panels and forces the reader to think longer about what was coming next. The action then speeds up through twelve smaller panels until the final panel: nothing more than white space and yet one of the most iconic and thought provoking in the entire twelve book series.

Watchmen by Alan Moore and Dave Gibbons (Diamond Comic Distributors 2004)

On the web it is common for clients to ask designers to fill every pixel of screen space with content, perhaps not understanding the drama that can be added by nothing more than white space.

In the final chapter, Gibbons emphasises the carnage that has taken place (unseen between chapters eleven and twelve) by presenting the reader with six full pages containing only single, large panels. 

Watchmen by Alan Moore and Dave Gibbons (Diamond Comic Distributors 2004)

This drama, created by the artist’s use of panel dimensions to control timing, is a technique that web designers can also usefully employ when emphasising important areas of content.

Think back for a moment to the home page of Apple Inc., during the launch of their iconic iPhone, where the page contained nothing more than a large image and the phrase “Say hello to iPhone”. Rather than fill the page with sales messages, Apple’s designers allowed the space itself to tell the story and created a real sense of suspense and expectation among their readers.

Borders

Whereas on the web, panel borders are commonly used to add emphasis to particular areas of content, in comic books they take on a different and sometimes opposite role. 

In the examples so far, borders have contained all of the action. Removing a border can have the opposite effect to what you might at first think. Rather than taking emphasis away from their content, in comics, borderless panels allow the reader’s eyes to linger for longer on the content adding even stronger emphasis.

Concrete by Paul Chadwick (Dark Horse Comics)

This effect is amplified when the borderless content is allowed to bleed to the edges of a page. Because the content is no longer confined, except by the edges of the page (both comic and web) the reader’s eye is left to wander out into open space. 

Concrete by Paul Chadwick (Dark Horse Comics)

This type of open, borderless content panel can be highly useful in placing emphasis on the most important content on a page in exactly the very opposite way that we commonly employ on the web today. 

So why is time an important dimension to think about when designing your web pages? On one level, we are often already concerned with the short attention spans of visitors to our pages and should work hard to allow them to quickly and easily find and read the content that both they and we think is important. Learning lessons from comic book timing can only help us improve that experience.

On another: timing, suspense and drama are already everyday parts of the web browsing experience. Will a reader see what they expect when they click from one page to the next? Or are they in for a surprise? 

Most importantly, I believe that the web, like comics, is about story telling: often the story of the experiences that a customer will have when they use our product or service or interact with our organisation. It is this element of story telling than can be greatly improved by learning from comics.

It is exactly this kind of learning and adapting from older, more established and at first glance unrelated media that you will find can make a real distinctive difference to the design work that you create.

Fill your stockings

If you’re a visual designer or developer and are not a regular reader of comics, from the moment that you pick up your first title, I know that you will find them inspiring. 

I will be writing more, and speaking about comic design applied to the web at several (to be announced) events this coming year. I hope you’ll be slipping your underpants over your trousers and joining me then.

148,Typesetting Tables,"Tables have suffered in recent years on the web. They were used for laying out web pages. Then, following the Web Standards movement, they’ve been renamed by the populous as `data tables’ to ensure that we all know what they’re for. There have been some great tutorials for the designing tables using CSS for presentation and focussing on the semantics in the displaying of data in the correct way. However, typesetting tables is a subtle craft that has hardly had a mention.

Table design can often end up being a technical exercise. What data do we need to display? Where is the data coming from and what form will it take? When was the last time your heard someone talk about lining numerals? Or designing to the reading direction?

Tables are not read like sentences

When a reader looks at, and tries to understand, tabular data, they’re doing a bunch of things at the same time.


	Generally, they’re task based; they’re looking for something.
	They are reading horizontally AND vertically


Reading a table is not like reading a paragraph in a novel, and therefore shouldn’t be typeset in the same way. Designing tables is information design, it’s functional typography—it’s not a time for eye candy.

Typesetting tables

Typesetting great looking tables is largely an exercise in restraint. Minimal interference with the legibility of the table should be in the forefront of any designers mind.

When I’m designing tables I apply some simple rules:


	Plenty of negative space
	Use the right typeface
	Go easy on the background tones, unless you’re giving reading direction visual emphasis
	Design to the reading direction


By way of explanation, here are those rules as applied to the following badly typeset table.

Your default table

This table is a mess. There is no consideration for the person trying to read it. Everything is too tight. The typeface is wrong. It’s flat. A grim table indeed.



Let’s see what we can do about that.

Plenty of negative space

The badly typeset table has been set with default padding. There has been little consideration for the ascenders and descenders in the type interfering with the many horizontal rules.

The first thing we do is remove most of the lines, or rules. You don’t need them – the data in the rows forms its own visual rules. Now, with most of the rules removed, the ones that remain mean something; they are indicating some kind of hierarchy to the help the reader understand what the different table elements mean – in this case the column headings.



Now we need to give the columns and rows more negative space. Note the framing of the column headings. I’m giving them more room at the bottom. This negative space is active—it’s empty for a reason. The extra air in here also gives more hierarchy to the column headings.



Use the right typeface

The default table is set in a serif typeface. This isn’t ideal for a couple of reasons. This serif typeface has a standard set of text numerals. These dip below the baseline and are designed for using figures within text, not on their own. What you need to use is a typeface with lining numerals. These align to the baseline and are more legible when used for tables.



Sans serif typefaces generally have lining numerals. They are also arguably more legible when used in tables.

Go easy on the background tones, unless you’re giving reading direction visual emphasis 

We’ve all seen background tones on tables. They have their use, but my feeling is that use should be functional and not decorative.

If you have a table that is long, but only a few columns wide, then alternate row shading isn’t that useful for showing the different lines of data. It’s a common misconception that alternate row shading is to increase legibility on long tables. That’s not the case. Shaded rows are to aid horizontal reading across multiple table columns. On wide tables they are incredibly useful for helping the reader find what they want.



Background tone can also be used to give emphasis to the reading direction. If we want to emphasis a column, that can be given a background tone.



Hierarchy

As I said earlier, people may be reading a table vertically, and horizontally in order to find what they want. Sometimes, especially if the table is complex, we need to give them a helping hand.

Visually emphasising the hierarchy in tables can help the reader scan the data. Column headings are particularly important. Column headings are often what a reader will go to first, so we need to help them understand that the column headings are different to the stuff beneath them, and we also need to give them more visual importance. We can do this by making them bold, giving them ample negative space, or by including a thick rule above them. We can also give the row titles the same level of emphasis.



In addition to background tones, you can give emphasis to reading direction by typesetting those elements in bold. You shouldn’t use italics—with sans serif typefaces the difference is too subtle.

So, there you have it. A couple of simple guidelines to make your tables cleaner and more readable.",2007,Mark Boulton,markboulton,2007-12-07T00:00:00+00:00,https://24ways.org/2007/typesetting-tables/,design
160,Tracking Christmas Cheer with Google Charts,"A note from the editors:  Since this article was written Google has retired the Charts API.
                
                
                      
                Let’s get something out in the open: I love statistics. As an informatician I can’t get enough graphs, charts, and numbers. So you can imagine when Google released their Charts API I thought Christmas had come early. I immediately began to draw up graphs for the holiday season using the new API; and using my new found chart-making skills I’ll show you what you can and can’t do with Google Charts.

Mummy, it’s my first chart

The Google Charts API allows you to send data to Google; in return they give you back a nicely-rendered graph. All the hard work is done on Google’s servers — you need only reference an image in your HTML. You pass along the data — the numbers for the charts, axis labels, and so on — in the query string of the image’s URL. If you want to add charts to your blog or web site, there’s probably no quicker way to get started.

Here’s a simple example: if we add the following line to an HTML page:

<img src=""http://chart.apis.google.com/chart?cht=lc&chs=200x125&chd=s:ZreelPuevfgznf2008"" />

Then we’ll see the line graph in Figure 1 appear in our page. That graph is hosted on Google’s own server1: http://chart.apis.google.com/.

Figure 1: A simple example of a line graph created with Google Charts.

If you look at the URL used in the example you’ll notice we’re passing some parameters along in the query string (the bit after the question mark). The query string looks like this:

cht=lc&chs=200x125&chd=s:ZreelPuevfgznf2008

It’s contains everything Google Charts needs to draw the graph.  There are three parameters in the query string:


	cht; this specifies the type of chart Google Charts will generate (in this case, lc is a line chart).
	chs, the value of which is 200x125; this defines the chart’s size (200 pixels wide by 125 pixels high).
	chd, the value of which is s:ZreelPuevfgznf2008; this is the actual chart data, which we’ll discuss in more detail later.


These three parameters are the minimum you need to send to Google Charts in order to create a chart.  There are lots more parameters you can send too (giving you more choice over how a chart is displayed), but you have to include at least these three before a chart can be created. Using these three parameters you can create pie charts, scatter plots, Venn diagrams, bar charts (and more) up to 1,000 pixels wide or 1,000 pixels high (but no more than 300,000 pixels in total).

Christmas pie

After I discovered the option to create a pie chart I instantly thought of graphing all the types of food and beverages that I’ll consume at this year’s Christmas feast. I can represent each item as a percentage of all the food on a pie chart (just thinking about that makes me hungry).

By changing the value of the cht parameter in the image’s query string I can change the chart type from a line chart to a pie chart. Google Charts offers two different types of pie chart: a fancy three-dimensional version and a two-dimensional overhead version. I want to stick with the latter, so I need to change cht=lc to cht=p (the p telling Google Charts to create a pie chart; if you want the three-dimensional version, use cht=p3). As a pie chart is circular I also need to adjust the size of the chart to make it square. Finally, it would be nice to add a title to the graph. I can do this by adding the optional parameter, chtt, to the end of the image URL. I end up with the chart you see in Figure 2.

Figure 2: Pie chart with a title.

To add this chart to your own page, you include the following (notice that you can’t include spaces in URLs, so you need to encode them as plus-signs.):

<img src=""http://chart.apis.google.com/chart?chtt=Food+and+Drink+Consumed+Christmas+2007&cht=p&chs=300x300&chd=s:ZreelPuevfgznf2008"" />

Ok, that’s great, but there are still two things I want to do before I can call this pie chart complete. First I want to label each slice of the pie. And second I want to include the proper data (at the moment the slices are meaningless). If 2007 is anything like 2006, the break down will be roughly as follows:


		
			Egg nog
			10%
		
		
			Christmas Ham
			20%
		
		
			Milk (not including egg nog)
			8%
		
		
			Cookies
			25%
		
		
			Roasted Chestnuts
			5%
		
		
			Chocolate
			3%
		
		
			Various Other Beverages
			15%
		
		
			Various Other Foods
			9%
		
		
			Snacks
			5%
		


I have nine categories of food and drink to be tracked, so I need nine slice labels. To add these to the chart, I use the chl parameter. All nine labels are sent in one value; I use the vertical-pipe character, |,  to separate them. So I need to append the following to the query string:

chl=Egg+nog|Christmas+Ham|Milk+(not+including+egg+nog)|Cookies|Roast+Chestnuts|Chocolate|Various+Other+Beverages|Various+Other+Foods|Snacks

Next I need to add the corresponding percentage values to the chart labels. Encoding the chart data is the trickiest part of the Google Charts API — but by no means complicated. There are three different ways to encode your data on a chart. As I’m only dealing with small numbers, I’m going to use what Google calls simple encoding.

Simple encoding offers a sixty-two value spectrum in which to represent data. Remember the mandatory option, chd, from the first example? The value for this is split into two parts: the type of encoding and the graph data itself.  These two parts are separated with a colon.  To use simple encoding, the first character of the chd option must be a lower case s. Follow this with a colon and everything after it is considered data for the graph.

In simple encoding, you have sixty-two values to represent your data. These values are lowercase and uppercase letters from the Latin alphabet (fifty-two characters in total) and the digits 0 to 9. Each letter of the alphabet represents a single number: A equals 0, B equals 1, and so on up to Z, which equals 25; a equals 26, b equals 27, and so on up to z, which equals 51. The ten digits represent the numbers 52 to 61: 0 equals 52, 1 equals 53, and 9 equals 61.

In the previous two examples we used the string ZreelPuevfgznf2008 as our chart data; the Z is equal to 25, the r is equal to 42, the e is equal to 30, and so on. I want to encode the percentage values 10, 20, 8, 25, 5, 3, 15, 9 and 5, so in simple encoding I would use the string KUIZFDPJF.

If you think figuring this out for each chart may make your head explode, don’t worry: help is out there.

Do you remember I said I needed to change the image dimensions to be square, to accommodate the pie chart? Well now I’m including labels I need even more room. And as I’m in a Christmassy mood I’m going to add some festive colours too.

The optional chco parameter is used to change the chart color. You set this using the same hexadecimal (“hex”) notation found in CSS. So let’s make our pie chart green by adding chco=00AF33 (don’t start it with a hash character as in CSS) to the image URL. If we only specify one hex colour for the pie chart Google Charts will use shades of that colour for each of the slices. To choose your own colours, pass a comma separated list of colours. The “Milk” and “Cookies” slices were consumed together, so we can make those two slices more of a redish colour.  I’ll use shades of green for the other slices. My chco parameter now looks like this:

chco=00AF33,4BB74C,EE2C2C,CC3232,33FF33,66FF66,9AFF9A,C1FFC1,CCFFCC.

After all this, I’m left with the following URL:

http://chart.apis.google.com/chart?chco=00AF33,4BB74C,EE2C2C,CC3232,33FF33,66FF66,9AFF9A,C1FFC1,CCFFCC&chl=Egg+nog|Christmas+Ham|Milk+(not+including+egg+nog)|Cookies|Roast+Chestnuts|Chocolate|Various+Other+Beverages|Various+Other+Foods|Snacks&chtt=Food+and+Drink+Consumed+Christmas+2007&cht=p&chs=600x300&chd=s:KUIZFDPJF

What does that give us?  I’m glad you asked.  I have the rather beautiful 600-pixel wide pie chart you see in Figure 3.

Figure 3: A Christmassy pie chart with labels.

But I don’t like pie charts

The pie chart was invented by the Scottish polymath William Playfair in 1801.  But not everyone is as excited by pie charts as wee Billy, so if you’re an anti-pie-chartist, what can you do?

You can easily reuse the same data but display it as a bar graph in a snap. The first thing we need to do is change the value of the cht parameter from p to bhg. This creates a horizontal bar graph (you can request a vertical bar graph using bvg). The data and labels all remain the same, but we need to decide where the labels will appear. I’ll talk more about how to do all this in the next section. 

In Figure 4 you’ll see the newly-converted bar graph. The URL for the graph is:

http://chart.apis.google.com/chart?cht=bhg&chs=600x300&chd=s:KUIZFDPJF&chxt=x,y&chtt=Food+and+Drink+Consumed+Christmas+2007&chxl=1:|Egg+nog|Christmas+Ham|Milk+(not+including+egg+nog)|Cookies|Roast+Chestnuts|Chocolate|Various+Other+Beverages|Various+Other+Foods|Snacks&chco=00AF33

Figure 4: The pie chart from Figure 3 represented as a bar chart.

Two lines, one graph

Pie charts and bar charts are interesting, but what if I want to compare last year’s Christmas cheer with this year’s? That sounds like I’ll need two lines on one graph.

The code is much the same as the previous examples; the most obvious difference is I need to set up the chart as a line graph. Creating some dummy values for the required parameters, I end up with:

<img src=""http://chart.apis.google.com/chart?chs=800x300&cht=lxy&chd=t:0,100|0,100"" />

The chs=800x300 sets the dimensions of the new chart, while cht=lxy describes the type of chart we are using (in this case a line chart with x and y co-ordinates). For the chart data I’m going to demostrate a different encoding, text encoding. To use this I start the value of the chd parameter with “t:”  instead of “s:”, and follow it with a list of x coordinates, a vertical pipe, |, and a list of y coordinates. Given the URL above, Google Charts will render the chart shown in Figure 5.

Figure 5: A simple line graph with x and y co-ordinates.

To make this graph a little more pleasing to the eye, I can add much the same as I did to the pie chart. I’ll add a chart title. Maybe something like “Projected Christmas Cheer for 2007”. Just as before I would add a chtt parameter to the image URL:

&chtt=Projected+Christmas+Cheer+for+2007

Next, let’s add some labels on the y axis to represent a scale from 0 to 100. On the x axis let’s label for the most important days of December. To do this I need to use the chart axis type parameter, chxt. This allows us to specify the axes and associate some labels with them. As I’m only interested in the y-axis (to the left of the chart) and the x-axis (below the chart), we add chxt=x,y to our image URL.

Now I need my label data. This is slightly more tricky because I want the data evenly spaced without labelling every item. The parameter for labels is chxl, the chart axis label. You match a label to an axis by using a number. So 0:Label1 is the zero index of chxt — in this case the x-axis. 1:Label2 is the first index of chxt — the y-axis. The order of these parameters or labels doesn’t matter as long as you associate them to their chxt correctly.

The next thing to know about chxl is that you can add an empty label. Labels are separated by vertical pipe; if you don’t put any text in a label, you just leave the two vertical pipes empty (“||”) and Google Charts will allocate space but no label.

For our vertical y axis, we want to label only 50% and 100% on the graph and plot them in their respective places. Since the y-axis is the second item, 1: (remember to start counting at zero), we add ten spaces to our image URL, chxl=1:||||||50|||||100 This will output the 50 halfway and the 100 at the top; all the other spaces will be empty.

We can do the same thing to get specific dates along the x-axis as well. Let’s add the 1st of December, St. Nick’s Day (the 6th), Christmas Day, Boxing Day (a holiday common in the UK and the Commonwealth, on the 26th), and the final day of the month, the 31st.  Since this is the x-axis I’ll use 0: as a reference in the chxt parameter tell Google Charts which axis to label. In full, the chxl parameter now looks like:

chxl=1:||||||50|||||100|0:|Dec+1st|||||6th||||10th|||||15th|||||20th|||||25th|26th|||||Dec+31st

That’s pretty.

Before we begin to graph our data, I’ll do one last thing: add some grid lines to the chart so to better connect the data to the labels. The parameter for this is chg, short for chart grid lines. The parameter takes four comma-separated arguments. The first is the x-axis spacing for the grid. I have thirty-one days, so I need thirty vertical lines. The chart is 100% wide, so 3.33 (100 divided by 30) is the required spacing.

As for the y-axis: the axis goes up to 100% but we probably only need to have a horizontal line every 10%, so the required spacing is 10 (100 divided by 10). That is the second argument.

The last two arguments control the dash-style of the grid-lines. The first number is the length of the line dash and the second is the space between the dashes. So 6,3 would mean a six-unit dash with a three-unit space. I like a ratio of 1,3 but you can change this as you wish. Now that I have the four arguments, the chg parameter looks like:

chg=3.333,10,1,3

If I add that to the chart URL I end up with:

http://chart.apis.google.com/chart?chs=800x300&cht=lxy&chd=t:0,100|0,100&chtt=Projected+Christmas+Cheer+for+2007&chxt=x,y&chxl=0:|Dec+1st|||||6th|||||||||||||||||||25th|26th|||||Dec+31st|1:||||||50|||||100&chg=3.3333,10,1,3

Which results in the chart shown in Figure 6.

Real data

Now the chart is ready I can add historical data from 2006 and current data from 2007.

Having a look at last year’s cheer levels we find some highs and lows through-out the month:


		
			Dec 1st
			Advent starts; life is good
			30%
		
		
			Dec 6th
			St. Nick’s Day, awake to find good things in my shoes
			45%
		
		
			Dec 8th
			Went Christmas carolling, nearly froze
			20%
		
		
			Dec 10th
			Christmas party at work, very nice dinner
			50%
		
		
			Dec 18th
			Panic Christmas shopping, hate rude people
			15%
		
		
			Dec 23rd
			Off Work, home eating holiday food
			80%
		
		
			Dec 25th
			Opened presents, good year, but got socks again from Grandma
			60%
		
		
			Dec 26th
			Boxing Day; we’re off and no one knows why
			70%
		
		
			Dec 28th
			Third day of left overs
			40%
		
		
			Dec 29th
			Procured some fireworks for new years
			55%
		
		
			Dec 31st
			New Year’s Eve
			80%
		


Since I’m plotting data for 2006 and 2007 on the same graph I’ll need two different colours — one for each year’s line — and a key to denote what each colour represents. The key is controlled by the chdl (chart data legend) parameter. Again, each part of the parameter is separated by a vertical pipe, so for two labels I’ll use chdl=2006|2007. I also want to colour-code them, so I’ll need to add the chco as I did for the pie chart. I want a red line and a green line, so I’ll use chco=458B00,CD2626 and add this to the image URL.

Let’s begin to plot the 2006 data on the Chart, replacing our dummy data of chd=t:0,100|0,100 with the correct information. The chd works by first listing all the x coordinates (each separated by a comma), then a vertical pipe, and then all the y coordinates (also comma-separated). The chart is 100% wide, so I need to convert the days into a percentage of the month.

The 1st of December is 0 and the 31st is 100. Everything else is somewhere in between. Our formula is:

(d – 1) × 100 ÷ (31 – 1)

Where d is the day of the month. The formula states that each day will be printed every 3.333 units; so the 6th of December will be printed at 16.665 units. I can repeat the process for the other dates listed to get the following x coordinates: 0,16.7,23.3,33.3,60,76.7,83.3,86.7,93.3,96.7. The y axis coordinates are easy because our scale is 100%, just like our rating, so we can simply copy them across as 30,45,20,50,15,80,60,70,40,55,80. This gives us a final chd value of:

chd=t:0,16.7,23.3,33.3,60,76.7,83.3,86.7,93.3,96.7,100|30,45,20,50,15,80,60,70,40,55,80

Onto 2007: I can put the data for the month so far to see how we are trending.


		
			Dec 1st
			Christmas shopping finished already
			50%
		
		
			Dec 4th
			Computer hard disk drive crashed (not Christmas related accident, but put me in a bad mood)
			10%
		
		
			Dec 6th
			Missed St. Nick’s Day completely due to travelling
			30%
		
		
			Dec 9th
			Dinner with friends before they travel
			55%
		
		
			Dec 11th
			24ways article goes live
			60%
		


Using the same system we did for 2006, I can take the five data points and plot them on the chart. The new x axis values will be 0,10,16.7,26.7 and the new y axis 50,10,30,65. We incorporate those into the image URL by appending these values onto the chd parameter we already have, which then becomes:

chd=t:0,16.7,23.3,33.3,60,76.7,83.3,86.7,93.3,96.7,100|30,45,20,50,15,80,60,70,40,55,80|0,10,16.7,26.7,33.3|50,10,30,55,60

Passing this to Google Charts results in Figure 7.

Did someone mention Edward Tufte?

Google Charts are a robust set of chart types that you can create easily and freely using their API. As you can see, you can graph just about anything you want using the line graph, bar charts, scatter plots, venn diagrams and pie charts. One type of chart conspicuously missing from the API is sparklines.  Sparklines were proposed by Edward Tufte as “small, high resolution graphics embedded in a context of words, numbers, images”.  They can be extremely useful, but can you create them in Google Charts?

The answer is: “Yes, but it’s an undocumented feature”. (The usual disclaimer about undocumented features applies.)

If we take our original line graph example, and change the value of the cht parameter from lc (line chart) to lfi (financial line chart) the axis-lines are removed. This allows you to make a chart — a sparkline — small enough to fit into a sentence. Google uses the lfi type all throughout the their financial site, but it’s not yet part of the official API.

Summary

The new Google Charts API is a powerful method for creating charts and graphs of all types. If you apply a little bit of technical skill you can create pie charts, bar graphs, and even sparklines as and when you need them. Now you’ve finished ready the article I hope you waste no more time: go forth and chart!

145,The Neverending (Background Image) Story,"Everyone likes candy for Christmas, and there’s none better than eye candy. Well, that, and just more of the stuff. Today we’re going to combine both of those good points and look at how to create a beautiful background image that goes on and on… forever!

Of course, each background image is different, so instead of agonising over each and every pixel, I’m going to concentrate on five key steps that you can apply to any of your own repeating background images. In this example, we’ll look at the Miami Beach background image used on the new FOWA site, which I’m afraid is about as un-festive as you can get.

1. Choose your image wisely

I find there are three main criteria when judging photos you’re considering for repetition manipulation (or ‘repetulation’, as I like to say)…


	simplicity (beware of complex patterns)
	angle and perspective (watch out for shadows and obvious vanishing points)
	consistent elements (for easy cloning)


You might want to check out this annotated version of the image, where I’ve highlighted elements of the photo that led me to choose it as the right one.

The original image purchased from iStockPhoto.

The Photoshopped version used on the FOWA site.

2. The power of horizontal lines

With the image chosen and your cursor poised for some Photoshop magic, the most useful thing you can do is drag out the edge pixels from one side of the image to create a kind of rough colour ‘template’ on which to work over. It doesn’t matter which side you choose, although you might find it beneficial to use the one with the simplest spread of colour and complex elements.

Click and hold on the marquee tool in the toolbar and select the ‘single column marquee tool’, which will span the full height of your document but will only be one pixel wide. Make the selection right at the edge of your document, press ctrl-c / cmd-c to copy the selection you made, create a new layer, and hit ctrl-v / cmd-v to paste the selection onto your new layer. using free transform (ctrl-t / cmd-t), drag out your selection so that it becomes as wide as your entire canvas. 

A one-pixel-wide selection stretched out to the entire width of the canvas.

3. Cloning

It goes without saying that the trusty clone tool is one of the most important in the process of creating a seamlessly repeating background image, but I think it’s important to be fairly loose with it. Always clone on to a new layer so that you’ve got the freedom to move it around, but above all else, use the eraser tool to tweak your cloned areas: let that handle the precision stuff and you won’t have to worry about getting your clones right first time.

In the example below, you can see how I overcame the problem of the far-left tree shadow being chopped off by cloning the shadow from the tree on its right. 

The edge of the shadow is cut off and needs to be ‘made’ from a pre-existing element.

The successful clone completes the missing shadow.

The two elements are obviously very similar but it doesn’t look like a clone because the majority of the shape is ‘genuine’ and only a small part is a duplicate. Also, after cloning I transformed the duplicate, erased parts of it, used gradients, and — ooh, did someone mention gradients?

4. Never underestimate a gradient

For this image, I used gradients in a similar way to a brush: covering large parts of the canvas with a colour that faded out to a desired point, before erasing certain parts for accuracy.

Several of the gradients and brushes that make up the ‘customised’ part of the image, visible when the main photograph layer is hidden.

The full composite.

Gradients are also a bit of an easy fix: you can use a gradient on one side of the image, flip it horizontally, and then use it again on the opposite side to make a more seamless join.

Speaking of which…

5. Sewing the seams

No matter what kind of magic Photoshop dust you sprinkle over your image, there will still always be the area where the two edges meet: that scary ‘loop’ point. Fret ye not, however, for there’s help at hand in the form of a nice little cheat. Even though the loop point might still be apparent, we can help hide it by doing something to throw viewers off the scent.

The seam is usually easy to spot because it’s a blank area with not much detail or colour variation, so in order to disguise it, go against the rule: put something across it!

This isn’t quite as challenging as it may sound, because if we intentionally make our own ‘object’ to span the join, we can accurately measure the exact halfway point where we need to split it across the two sides of the image. This is exactly what I did with the FOWA background image: I made some clouds!

A sky with no clouds in an unhappy one.

A simple soft white brush creates a cloud-like formation in the sky.

After taking the cloud’s opacity down to 20%, I used free transform to highlight the boundaries of the layer. I then moved it over to the right, so that the middle of the layer perfectly aligned with the right side of the canvas.

Finally, I duplicated the layer and did the same in reverse: dragging the layer over to the left and making sure that the middle of the duplicate layer perfectly aligned with the left side of the canvas.

And there you have it! Boom! Ta-da! Et Voila! To see the repeating background image in action, visit futureofwebapps.com on a large widescreen monitor or see a simulation of the effect.

165,Transparent PNGs in Internet Explorer 6,"Newer breeds of browser such as Firefox and Safari have offered support for PNG images with full alpha channel transparency for a few years. With the use of hacks, support has been available in Internet Explorer 5.5 and 6, but the hacks are non-ideal and have been tricky to use. With IE7 winning masses of users from earlier versions over the last year, full PNG alpha-channel transparency is becoming more of a reality for day-to-day use.

However, there are still numbers of IE6 users out there who we can’t leave out in the cold this Christmas, so in this article I’m going to look what we can do to support IE6 users whilst taking full advantage of transparency for the majority of a site’s visitors.

So what’s alpha channel transparency?

Cast your minds back to the Ghost of Christmas Past, the humble GIF. Images in GIF format offer transparency, but that transparency is either on or off for any given pixel. Each pixel’s either fully transparent, or a solid colour. In GIF, transparency is effectively just a special colour you can chose for a pixel.

The PNG format tackles the problem rather differently. As well as having any colour you chose, each pixel also carries a separate channel of information detailing how transparent it is. This alpha channel enables a pixel to be fully transparent, fully opaque, or critically, any step in between.

This enables designers to produce images that can have, for example, soft edges without any of the ‘halo effect’ traditionally associated with GIF transparency. If you’ve ever worked on a site that has different colour schemes and therefore requires multiple versions of each graphic against a different colour, you’ll immediately see the benefit. 

What’s perhaps more interesting than that, however, is the extra creative freedom this gives designers in creating beautiful sites that can remain web-like in their ability to adjust, scale and reflow.

The Internet Explorer problem

Up until IE7, there has been no fully native support for PNG alpha channel transparency in Internet Explorer. However, since IE5.5 there has been some support in the form of proprietary filter called the AlphaImageLoader. Internet Explorer filters can be applied directly in your CSS (for both inline and background images), or by setting the same CSS property with JavaScript. 

CSS:

img {
	filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(...);
}

JavaScript:

img.style.filter = ""progid:DXImageTransform.Microsoft.AlphaImageLoader(...)"";

That may sound like a problem solved, but all is not as it may appear. Firstly, as you may realise, there’s no CSS property called filter in the W3C CSS spec. It’s a proprietary extension added by Microsoft that could potentially cause other browsers to reject your entire CSS rule. 

Secondly, AlphaImageLoader does not magically add full PNG transparency support so that a PNG in the page will just start working. Instead, when applied to an element in the page, it draws a new rendering surface in the same space that element occupies and loads a PNG into it. If that sounds weird, it’s because that’s precisely what it is. However, by and large the result is that PNGs with an alpha channel can be accommodated.

The pitfalls

So, whilst support for PNG transparency in IE5.5 and 6 is possible, it’s not without its problems.

Background images cannot be positioned or repeated

The AlphaImageLoader does work for background images, but only for the simplest of cases. If your design requires the image to be tiled (background-repeat) or positioned (background-position) you’re out of luck. The AlphaImageLoader allows you to set a sizingMethod to either crop the image (if necessary) or to scale it to fit. Not massively useful, but something at least.

Delayed loading and resource use

The AlphaImageLoader can be quite slow to load, and appears to consume more resources than a standard image when applied. Typically, you’d need to add thousands of GIFs or JPEGs to a page before you saw any noticeable impact on the browser, but with the AlphaImageLoader filter applied Internet Explorer can become sluggish after just a handful of alpha channel PNGs.

The other noticeable effect is that as more instances of the AlphaImageLoader are applied, the longer it takes to render the PNGs with their transparency. The user sees the PNG load in its original non-supported state (with black or grey areas where transparency should be) before one by one the filter kicks in and makes them properly transparent.

Both the issue of sluggish behaviour and delayed load only really manifest themselves with volume and size of image. Use just a couple of instances and it’s fine, but be careful adding more than five or six. As ever, test, test, test.

Links become unclickable, forms unfocusable 

This is a big one. There’s a bug/weirdness with AlphaImageLoader that sometimes prevents interaction with links and forms when a PNG background image is used. This is sometimes reported as a z-index issue, but I don’t believe it is. Rather, it’s an artefact of that weird way the filter gets applied to the document almost outside of the normal render process. 

Often this can be solved by giving the links or form elements hasLayout using position: relative; where possible. However, this doesn’t always work and the non-interaction problem cannot always be solved. You may find yourself having to go back to the drawing board.

Sidestepping the danger zones

Frankly, it’s pretty bad news if you design a site, have that design signed off by your client, build it and then find out only at the end (because you don’t know what might trigger a problem) that your search field can’t be focused in IE6. That’s an absolute nightmare, and whilst it’s not likely to happen, it’s possible that it might. It’s happened to me. So what can you do?

The best approach I’ve found to this scenario is


	Isolate the PNG or PNGs that are causing the problem. Step through the PNGs in your page, commenting them out one by one and retesting. Typically it’ll be the nearest PNG to the problem, so try there first. Keep going until you can click your links or focus your form fields.
	This is where you really need luck on your side, because you’re going to have to fake it. This will depend on the design of the site, but some way or other create a replacement GIF or JPEG image that will give you an acceptable result. Then use conditional comments to serve that image to only users of IE older than version 7.


A hack, you say? Well, you started it chum.

Applying AlphaImageLoader

Because the filter property is invalid CSS, the safest pragmatic approach is to apply it selectively with JavaScript for only Internet Explorer versions 5.5 and 6. This helps ensure that by default you’re serving standard CSS to browsers that support both the CSS and PNG standards correct, and then selectively patching up only the browsers that need it. 

Several years ago, Aaron Boodman wrote and released a script called sleight for doing just that. However, sleight dealt only with images in the page, and not background images applied with CSS. Building on top of Aaron’s work, I hacked sleight and came up with bgsleight for applying the filter to background images instead. That was in 2003, and over the years I’ve made a couple of improvements here and there to keep it ticking over and to resolve conflicts between sleight and bgsleight when used together. However, with alpha channel PNGs becoming much more widespread, it’s time for a new version.

Introducing SuperSleight

SuperSleight adds a number of new and useful features that have come from the day-to-day needs of working with PNGs.


	Works with both inline and background images, replacing the need for both sleight and bgsleight
	Will automatically apply position: relative to links and form fields if they don’t already have position set. (Can be disabled.)
	Can be run on the entire document, or just a selected part where you know the PNGs are. This is better for performance.
	Detects background images set to no-repeat and sets the scaleMode to crop rather than scale.
	Can be re-applied by any other JavaScript in the page – useful if new content has been loaded by an Ajax request.


  Download SuperSleight 

Implementation

Getting SuperSleight running on a page is quite straightforward, you just need to link the supplied JavaScript file (or the minified version if you prefer) into your document inside conditional comments so that it is delivered to only Internet Explorer 6 or older.

<!--[if lte IE 6]>
	<script type=""text/javascript"" src=""supersleight-min.js""></script>
<![endif]-->

Supplied with the JavaScript is a simple transparent GIF file. The script replaces the existing PNG with this before re-layering the PNG over the top using AlphaImageLoaded. You can change the name or path of the image in the top of the JavaScript file, where you’ll also find the option to turn off the adding of position: relative to links and fields if you don’t want that.

The script is kicked off with a call to supersleight.init() at the bottom. The scope of the script can be limited to just one part of the page by passing an ID of an element to supersleight.limitTo(). And that’s all there is to it.

Update March 2008: a version of this script as a jQuery plugin is also now available.",2007,Drew McLellan,drewmclellan,2007-12-01T00:00:00+00:00,https://24ways.org/2007/supersleight-transparent-png-in-ie6/,code
166,Performance On A Shoe String,"Back in the summer, I happened to notice the official Wimbledon All England Tennis Club site had jumped to the top of Alexa’s Movers & Shakers list — a list that tracks sites that have had the biggest upturn or downturn in traffic. The lawn tennis championships were underway, and so traffic had leapt from almost nothing to crazy-busy in a no time at all. 

Many sites have similar peaks in traffic, especially when they’re based around scheduled events. No one cares about the site for most of the year, and then all of a sudden – wham! – things start getting warm in the data centre. Whilst the thought of chestnuts roasting on an open server has a certain appeal, it’s less attractive if you care about your site being available to visitors. Take a look at this Alexa traffic graph showing traffic patterns for superbowl.com at the beginning of each year, and wimbledon.org in the month of July.

Traffic graph from Alexa.com 

Whilst not on the same scale or with such dramatic peaks, we have a similar pattern of traffic here at 24ways.org. Over the last three years we’ve seen a dramatic pick up in traffic over the month of December (as would be expected) and then a much lower, although steady load throughout the year. What we do have, however, is the luxury of knowing when the peaks will be. For a normal site, be that a blog, small scale web app, or even a small corporate site, you often just cannot predict when you might get slashdotted, end up on the front page of Digg or linked to from a similarly high-profile site. You just don’t know when the peaks will be.

If you’re a big commercial enterprise like the Super Bowl, scaling up for that traffic is simply a cost of doing business. But for most of us, we can’t afford to have massive capacity sat there unused for 90% of the year. What you have to do instead is work out how to deal with as much traffic as possible with the modest resources you have.

In this article I’m going to talk about some of the things we’ve learned about keeping 24 ways running throughout December, whilst not spending a fortune on hosting we don’t need for 11 months of each year. We’ve not always got it right, but we’ve learned a lot along the way.

The Problem

To know how to deal with high traffic, you need to have a basic idea of what happens when a request comes into a web server. 24 ways is hosted on a single small virtual dedicated server with a great little hosting company in the UK. We run Apache with PHP and MySQL all on that one server. When a request comes in a new Apache process is started to deal with the request (or assigned if there’s one available not doing anything). Each process takes a bunch of memory, so there’s a finite number of processes that you can run, and therefore a finite number of pages you can serve at once before your server runs out of memory.

With our budget based on whatever is left over after beer, we need to get best performance we can out of the resources available. As the goal is to serve as many pages as quickly as possible, there are several approaches we can take:


	Reducing the amount of memory needed by each Apache process
	Reducing the amount of time each process is needed
	Reducing the number of requests made to the server


Yahoo! have published some information on what they call Exceptional Performance, which is well worth reading, and compliments many of my examples here. The Yahoo! guidelines very much look at things from a user perspective, which is always important.

Server tweaking

If you’re in the position of being able to change your server configuration (our set-up gives us root access to what is effectively a virtual machine) there are some basic steps you can take to maximise the available memory and reduce the memory footprint. Without getting too boring and technical (whole books have been written on this) there are a couple of things to watch out for.

Firstly, check what processes you have running that you might not need. Every megabyte of memory that you free up might equate to several thousand extra requests being served each day, so take a look at top and see what’s using up your resources. Quite often a machine configured as a web server will have some kind of mail server running by default. If your site doesn’t use mail (ours doesn’t) make sure it’s shut down and not using resources.

Secondly, have a look at your Apache configuration and particularly what modules are loaded. The method for doing this varies between versions of Apache, but again, every module loaded increases the amount of memory that each Apache process requires and therefore limits the number of simultaneous requests you can deal with.

The final thing to check is that Apache isn’t configured to start more servers than you have memory for. This is usually done by setting the MaxClients directive. When that limit is reached, your site is going to stop responding to further requests. However, if all else goes well that threshold won’t be reached, and if it does it will at least stop the weight of the traffic taking the entire server down to a point where you can’t even log in to sort it out.

Those are the main tidbits I’ve found useful for this site, although it’s worth repeating that entire books have been written on this subject alone.

Caching

Although the site is generated with PHP and MySQL, the majority of pages served don’t come from the database. The process of compiling a page on-the-fly involves quite a few trips to the database for content, templates, configuration settings and so on, and so can be slow and require a lot of CPU. Unless a new article or comment is published, the site doesn’t actually change between requests and so it makes sense to generate each page once, save it to a file and then just serve all following requests from that file.

We use QuickCache (or rather a plugin based on it) for this. The plugin integrates with our publishing system (Textpattern) to make sure the cache is cleared when something on the site changes. A similar plugin called WP-Cache is available for WordPress, but of course this could be done any number of ways, and with any back-end technology.

The important principal here is to reduce the time it takes to serve a page by compiling the page once and serving that cached result to subsequent visitors. Keep away from your database if you can.

Outsource your feeds

We get around 36,000 requests for our feed each day. That really only works out at about 7,000 subscribers averaging five-and-a-bit requests a day, but it’s still 36,000 requests we could easily do without. Each request uses resources and particularly during December, all those requests can add up. 

The simple solution here was to switch our feed over to using FeedBurner. We publish the address of the FeedBurner version of our feed here, so those 36,000 requests a day hit FeedBurner’s servers rather than ours. In addition, we get pretty graphs showing how the subscriber-base is building.



Off-load big files

Larger files like images or downloads pose a problem not in bandwidth, but in the time it takes them to transfer. A typical page request is very quick, a few seconds at the most, resulting in the connection being freed up promptly. Anything that keeps a connection open for a long time is going to start killing performance very quickly.

This year, we started serving most of the images for articles from a subdomain – media.24ways.org. Rather than pointing to our own server, this subdomain points to an Amazon S3 account where the files are held. It’s easy to pigeon-hole S3 as merely an online backup solution, and whilst not a fully fledged CDN, S3 works very nicely for serving larger media files. The roughly 20GB of files served this month have cost around $5 in Amazon S3 charges. That’s so affordable it may not be worth even taking the files back off S3 once December has passed.

I found this article on Scalable Media Hosting with Amazon S3 to be really useful in getting started. I upload the files via a Firefox plugin (mentioned in the article) and then edit the ACL to allow public access to the files. The way S3 enables you to point DNS directly at it means that you’re not tied to always using the service, and that it can be transparent to your users.

If your site uses photographs, consider uploading them to a service like Flickr and serving them directly from there. Many photo sharing sites are happy for you to link to images in this way, but do check the acceptable use policies in case you need to provide a credit or link back.

Off-load small files

You’ll have noticed the pattern by now – get rid of as much traffic as possible. When an article has a lot of comments and each of those comments has an avatar along with it, a great many requests are needed to fetch each of those images. In 2006 we started using Gravatar for avatars, but their servers were slow and were holding up page loads. To get around this we started caching the images on our server, but along with that came the burden of furnishing all the image requests.

Earlier this year Gravatar changed hands and is now run by the same team behind WordPress.com. Those guys clearly know what they’re doing when it comes to high performance, so this year we went back to serving avatars directly from them.

If your site uses avatars, it really makes sense to use a service like Gravatar where your users probably already have an account, and where the image requests are going to be dealt with for you. 

Know what you’re paying for

The server account we use for 24 ways was opened in November 2005. When we first hit the front page of Digg in December of that year, we upgraded the server with a bit more memory, but other than that we were still running on that 2005 spec for two years. Of course, the world of technology has moved on in those years, prices have dropped and specs have improved. For the same amount we were paying for that 2005 spec server, we could have an account with twice the CPU, memory and disk space.

So in November of this year I took out a new account and transferred the site from the old server to the new. In that single step we were prepared for dealing with twice the amount of traffic, and because of a special offer at the time I didn’t even have to pay the setup cost on the new server. So it really pays to know what you’re paying for and keep an eye out of ways you can make improvements without needing to spend more money.

Further steps

There’s nearly always more that can be done. For example, there are some media files (particularly for older articles) that are not on S3. We also serve our CSS directly and it’s not minified or compressed. But by tackling the big problems first we’ve managed to reduce load on the server and at the same time make sure that the load being placed on the server can be dealt with in the most frugal way.

Over the last 24 days we’ve served up articles to more than 350,000 visitors without breaking a sweat. On a busy day, that’s been nearly 20,000 visitors in just 24 hours. While in the grand scheme of things that’s not a huge amount of traffic, it can be a lot if you’re not prepared for it. However, with a little planning for the peaks you can help ensure that when the traffic arrives you’re ready to capitalise on it.

Of course, people only visit 24 ways for the wealth of knowledge and experience that’s tied up in the articles here. Therefore I’d like to take the opportunity to thank all our authors this year who have given their time as a gift to the community, and to wish you all a very happy Christmas.",2007,Drew McLellan,drewmclellan,2007-12-24T00:00:00+00:00,https://24ways.org/2007/performance-on-a-shoe-string/,ux
164,My Other Christmas Present Is a Definition List,"A note from the editors:  readers should note that the HTML5 redefinition of definition lists has come to pass and is now à la mode.
                
                
                      
                Last year, I looked at how the markup for tag clouds was generally terrible. I thought this year I would look not at a method of marking up a common module, but instead just at a simple part of HTML and how it generally gets abused.

No, not tables. Definition lists. Ah, definition lists. Often used but rarely understood.

Examining the definition of definitions

To start with, let’s see what the HTML spec has to say about them.


	Definition lists vary only slightly from other types of lists in that list items consist of two parts: a term and a description.


The canonical example of a definition list is a dictionary. Words can have multiple descriptions (even the word definition has at least five). Also, many terms can share a single definition (for example, the word colour can also be spelt color, but they have the same definition).

Excellent, we can all grasp that. But it very quickly starts to fall apart. Even in the HTML specification the definition list is mis-used.


	Another application of DL, for example, is for marking up dialogues, with each DT naming a speaker, and each DD containing his or her words.


Wrong. Completely and utterly wrong. This is the biggest flaw in the HTML spec, along with dropping support for the start attribute on ordered lists. “Why?”, you may ask. Let me give you an example from Romeo and Juliet, act 2, scene 2.

<dt>Juliet</dt>
	<dd>Romeo!</dd>
<dt>Romeo</dt>
	<dd>My niesse?</dd>
<dt>Juliet</dt>
	<dd>At what o'clock tomorrow shall I send to thee?</dd>
<dt>Romeo</dt>
	<dd>At the hour of nine.</dd>

Now, the problem here is that a given definition can have multiple descriptions (the DD). Really the dialog “descriptions” should be rolled up under the terms, like so:

<dt>Juliet</dt>
	<dd>Romeo!</dd>
	<dd>At what o'clock tomorrow shall I send to thee?</dd>
<dt>Romeo</dt>
	<dd>My niesse?</dd>
	<dd>At the hour of nine.</dd>

Suddenly the play won’t make anywhere near as much sense. (If it’s anything, the correct markup for a play is an ordered list of CITE and BLOCKQUOTE elements.)

This is the first part of the problem. That simple example has turned definition lists in everyone’s mind from pure definitions to more along the lines of a list with pre-configured heading(s) and text(s).

Screen reader, enter stage left.

In many screen readers, a simple definition list would be read out as “definition term equals definition description”. So in our play excerpt, Juliet equals Romeo! That’s not right, either. But this also leads a lot of people astray with definition lists to believing that they are useful for key/value pairs.

Behaviour and convention

The WHAT-WG have noticed the common mis-use of the DL, and have codified it into the new spec. In the HTML5 draft, a definition list is no longer a definition list.


	The dl element introduces an unordered association list consisting of zero or more name-value groups (a description list). Each group must consist of one or more names (dt elements) followed by one or more values (dd elements).


They also note that the “dl element is inappropriate for marking up dialogue, since dialogue is ordered”. So for that example they have created a DIALOG (sic) element.

Strange, then, that they keep DL as-is but instead refer to it an “association list”. They have not created a new AL element, and kept DL for the original purpose. They have chosen not to correct the usage or to create a new opportunity for increased specificity in our HTML, but to “pave the cowpath” of convention.

How to use a definition list

Given that everyone else is using a DL incorrectly, should we? Well, if they all jumped off a bridge, would you too? No, of course you wouldn’t. We don’t have HTML5 yet, so we’re stuck with the existing semantics of HTML4 and XHTML1. Which means that:


	Listing dialogue is not defining anything.
	Listing the attributes of a piece of hardware (resolution = 1600×1200) is illustrating sample values, not defining anything (however, stating what ‘resolution’ actually means in this context would be a definition).
	Listing the cast and crew of a given movie is not defining the people involved in making movies. (Stuart Gordon may have been the director of Space Truckers, but that by no means makes him the true definition of a director.)
	A menu of navigation items is simply a nested ordered or unordered list of links, not a definition list.
	Applying styling handles to form labels and elements is not a good use for a definition list.


And so on.

Living by the specification, a definition list should be used for term definitions – glossaries, lexicons and dictionaries – only.

156,Mobile 2.0,"Thinking 2.0

As web geeks, we have a thick skin towards jargon. We all know that “Web 2.0” has been done to death. At Blue Flavor we even have a jargon bucket to penalize those who utter such painfully overused jargon with a cash deposit. But Web 2.0 is a term that has lodged itself into the conscience of the masses. This is actually a good thing.

The 2.0 suffix was able to succinctly summarize all that was wrong with the Web during the dot-com era as well as the next evolution of an evolving media. While the core technologies actually stayed basically the same, the principles, concepts, interactions and contexts were radically different.

With that in mind, this Christmas I want to introduce to you the concept of Mobile 2.0. While not exactly a new concept in the mobile community, it is relatively unknown in the web community. And since the foundation of Mobile 2.0 is the web, I figured it was about time for you to get to know each other.

It’s the Carriers’ world. We just live in it.

Before getting into Mobile 2.0, I thought first I should introduce you to its older brother. You know the kind, the kid with emotional problems that likes to beat up on you and your friends for absolutely no reason. That is the mobile of today.

The mobile ecosystem is a very complicated space often and incorrectly compared to the Web. If the Web was a freewheeling hippie — believing in freedom of information and the unity of man through communities — then Mobile is the cutthroat capitalist — out to pillage and plunder for the sake of the almighty dollar. Where the Web is relatively easy to publish to and ultimately make a buck, Mobile is wrought with layers of complexity, politics and obstacles. 

I can think of no better way to summarize these challenges than the testimony of Jason Devitt to the United States Congress in what is now being referred to as the “iPhone Hearing.” Jason is the co-founder and CEO of SkyDeck a new wireless startup and former CEO of Vindigo an early pioneer in mobile content.



As Jason points out, the mobile ecosystem is a closed door environment controlled by the carriers, forcing the independent publisher to compete or succumb to the will of corporate behemoths.

But that is all about to change.

Introducing Mobile 2.0

Mobile 2.0 is term used by the mobile community to describe the current revolution happening in mobile. It describes the convergence of mobile and web services, adding portability, ubiquitous connectivity and location-aware services to add physical context to information found on the Web.

It’s an important term that looks toward the future. Allowing us to imagine the possibilities that mobile technology has long promised but has yet to deliver. It imagines a world where developers can publish mobile content without the current constraints of the mobile ecosystem.

Like the transition from Web 1.0 to 2.0, it signifies the shift away from corporate or brand-centered experiences to user-centered experiences. A focus on richer interactions, driven by user goals. Moving away from proprietary technologies to more open and standard ones, more akin to the Web. And most importantly (from our perspective as web geeks) a shift away from kludgy one-off mobile applications toward using the Web as a platform for content and services.

This means the world of the Web and the world of Mobile are coming together faster than you can say ARPU (Average Revenue Per User, a staple mobile term to you webbies). And this couldn’t come at a better time. The importance of understanding and addressing user context is quickly becoming a crucial consideration to every interactive experience as the number of ways we access information on the Web increases.

Mobile enables the power of the Web, the collective information of millions of people, inherit payment channels and access to just about every other mass media to literally be overlaid on top of the physical world, in context to the person viewing it. 

Anyone who can’t imagine how the influence of mobile technology can’t transform how we perform even the simplest of daily tasks needs to get away from their desktop and see the new evolution of information.

The Instigators

But what will make Mobile 2.0 move from idillic concept to a hardened market reality in 2008 will be four key technologies. Its my guess that you know each them already.

1. Opera

Opera is like the little train that could. They have been a driving force on moving the Web as we know it on to mobile handsets. Opera technology has proven itself to be highly adaptable, finding itself preloaded on over 40 million handsets, available on televisions sets through Nintendo Wii or via the Nintendo DS.

2. WebKit

Many were surprised when Apple chose to use KHTML instead of Gecko (the guts of Firefox) to power their Safari rendering engine. But WebKit has quickly evolved to be a powerful and flexible browser in the mobile context. WebKit has been in Nokia smartphones for a few years now, is the technology behind Mobile Safari in the iPhone and the iPod Touch and is the default web technology in Google’s open mobile platform effort, Android.

3. The iPhone

The iPhone has finally brought the concepts and principles of Mobile 2.0 into the forefront of consumers minds and therefore developers’ minds as well. Over 500 web applications have been written specifically for the iPhone since its launch. It’s completely unheard of to see so many applications built for the mobile context in such a short period of time.

4. CSS & Javascript

Web 2.0 could not exist without the rich interactions offered by CSS and Javascript, and Mobile 2.0 is no different. CSS and Javascript support across multiple phones historically has been, well… to put it positively… utter crap.

Javascript finally allows developers to create interesting interactions that support user goals and the mobile context. Specially, AJAX allows us to finally shed the days of bloated Java applications and focus on portable and flexible web applications. While CSS — namely CSS3 — allows us to create designs that are as beautiful as they are economical with bandwidth and load times.

With Leaflets, a collection of iPhone optimized web apps we created, we heavily relied on CSS3 to cache and reuse design elements over and over, minimizing download times while providing an elegant and user-centered design.



In Conclusion

It is the combination of all these instigators that is significantly decreasing the bar to mobile publishing. The market as Jason Devitt describes it, will begin to fade into the background. And maybe the world of mobile will finally start looking more like the Web that we all know and love.

So after the merriment and celebration of the holiday is over and you look toward the new year to refresh and renew, I hope that you take a seriously consider the mobile medium. 

By this time next year, it is predicted that one-third of humanity will be using mobile devices to access the Web.",2007,Brian Fling,brianfling,2007-12-21T00:00:00+00:00,https://24ways.org/2007/mobile-2-0/,business
155,Minification: A Christmas Diet,"The festive season is generally more about gorging ourselves than staying thin but we’re going to change all that with a quick introduction to minification.

Performance has been a hot topic this last year. We’re building more complex sites and applications but at the same time trying to make then load faster and behave more responsively. What is a discerning web developer to do?

Minification is the process of make something smaller, in the case of web site performance we’re talking about reducing the size of files we send to the browser. The primary front-end components of any website are HTML, CSS, Javascript and a sprinkling of images. Let’s find some tools to trim the fat and speed up our sites.

For those that want to play along at home you can download the various utilities for Mac or Windows. You’ll want to be familiar with running apps on the command line too.

HTMLTidy

HTMLTidy optimises and strips white space from HTML documents. It also has a pretty good go at correcting any invalid markup while it’s at it.

tidy -m page.html

CSSTidy

CSSTidy takes your CSS file, optimises individual rules (for instance transforming padding-top: 10px; padding-bottom: 10px; to padding: 10px 0;) and strips unneeded white space.

csstidy style.css style-min.css

JSMin

JSMin takes your javascript and makes it more compact. With more and more websites using javascript to power (progressive) enhancements this can be a real bandwidth hog. Look out for pre-minified versions of libraries and frameworks too.

jsmin <script.js >script-min.js

Remember to run JSLint before you run JSMin to catch some common problems.

OptiPNG

Images can be a real bandwidth hog and making all of them smaller with OptiPNG should speed up your site.

optipng image.png

All of these tools have an often bewildering array of options and generally good documentation included as part of the package. A little experimentation will get you even more bang for your buck.

For larger projects you likely won’t want to be manually minifying all your files. The best approach here is to integrate these tools into your build process and have your live website come out the other side smaller than it went in.

You can also do things on the server to speed things up; GZIP compression for instance or compilation of resources to reduce the number of HTTP requests. If you’re interested in performance a good starting point is the Exceptional Performance section on the Yahoo Developer Network and remember to install the YSlow Firebug extension while you’re at it.",2007,Gareth Rushgrove,garethrushgrove,2007-12-06T00:00:00+00:00,https://24ways.org/2007/minification-a-christmas-diet/,process
161,Keeping JavaScript Dependencies At Bay,"As we are writing more and more complex JavaScript applications we run into issues that have hitherto (god I love that word) not been an issue. The first decision we have to make is what to do when planning our app: one big massive JS file or a lot of smaller, specialised files separated by task. 

Personally, I tend to favour the latter, mainly because it allows you to work on components in parallel with other developers without lots of clashes in your version control. It also means that your application will be more lightweight as you only include components on demand.

Starting with a global object

This is why it is a good plan to start your app with one single object that also becomes the namespace for the whole application, say for example myAwesomeApp:

var myAwesomeApp = {};

You can nest any necessary components into this one and also make sure that you check for dependencies like DOM support right up front.

Adding the components

The other thing to add to this main object is a components object, which defines all the components that are there and their file names.

var myAwesomeApp = {
	components :{
		formcheck:{
			url:'formcheck.js',
			loaded:false
		},
		dynamicnav:{
			url:'dynamicnav.js',
			loaded:false
		},
		gallery:{
			url:'gallery.js',
			loaded:false
		},
		lightbox:{
			url:'lightbox.js',
			loaded:false
		}
	}
};

Technically you can also omit the loaded properties, but it is cleaner this way. The next thing to add is an addComponent function that can load your components on demand by adding new SCRIPT elements to the head of the documents when they are needed.

var myAwesomeApp = {
	components :{
		formcheck:{
			url:'formcheck.js',
			loaded:false
		},
		dynamicnav:{
			url:'dynamicnav.js',
			loaded:false
		},
		gallery:{
			url:'gallery.js',
			loaded:false
		},
		lightbox:{
			url:'lightbox.js',
			loaded:false
		}
	},
	addComponent:function(component){
		var c = this.components[component];
		if(c && c.loaded === false){
			var s = document.createElement('script');
			s.setAttribute('type', 'text/javascript');
			s.setAttribute('src',c.url);
			document.getElementsByTagName('head')[0].appendChild(s);
		}
	}
};

This allows you to add new components on the fly when they are not defined:

if(!myAwesomeApp.components.gallery.loaded){
	myAwesomeApp.addComponent('gallery');
};

Verifying that components have been loaded

However, this is not safe as the file might not be available. To make the dynamic adding of components safer each of the components should have a callback at the end of them that notifies the main object that they indeed have been loaded:

var myAwesomeApp = {
	components :{
		formcheck:{
			url:'formcheck.js',
			loaded:false
		},
		dynamicnav:{
			url:'dynamicnav.js',
			loaded:false
		},
		gallery:{
			url:'gallery.js',
			loaded:false
		},
		lightbox:{
			url:'lightbox.js',
			loaded:false
		}
	},
	addComponent:function(component){
		var c = this.components[component];
		if(c && c.loaded === false){
			var s = document.createElement('script');
			s.setAttribute('type', 'text/javascript');
			s.setAttribute('src',c.url);
			document.getElementsByTagName('head')[0].appendChild(s);
		}
	},
	componentAvailable:function(component){
		this.components[component].loaded = true;
	}
}

For example the gallery.js file should call this notification as a last line:

myAwesomeApp.gallery = function(){
	// [... other code ...]
}();
myAwesomeApp.componentAvailable('gallery');

Telling the implementers when components are available

The last thing to add (actually as a courtesy measure for debugging and implementers) is to offer a listener function that gets notified when the component has been loaded:

var myAwesomeApp = {
	components :{
		formcheck:{
			url:'formcheck.js',
			loaded:false
		},
		dynamicnav:{
			url:'dynamicnav.js',
			loaded:false
		},
		gallery:{
			url:'gallery.js',
			loaded:false
		},
		lightbox:{
			url:'lightbox.js',
			loaded:false
		}
	},
	addComponent:function(component){
		var c = this.components[component];
		if(c && c.loaded === false){
			var s = document.createElement('script');
			s.setAttribute('type', 'text/javascript');
			s.setAttribute('src',c.url);
			document.getElementsByTagName('head')[0].appendChild(s);
		}
	},
	componentAvailable:function(component){
		this.components[component].loaded = true;
		if(this.listener){
			this.listener(component);
		};
	}
};

This allows you to write a main listener function that acts when certain components have been loaded, for example:

myAwesomeApp.listener = function(component){
	if(component === 'gallery'){
	   showGallery();
	}
};

Extending with other components

As the main object is public, other developers can extend the components object with own components and use the listener function to load dependent components. Say you have a bespoke component with data and labels in extra files:

myAwesomeApp.listener = function(component){
	if(component === 'bespokecomponent'){
		myAwesomeApp.addComponent('bespokelabels');
	};
	if(component === 'bespokelabels'){
		myAwesomeApp.addComponent('bespokedata');
	};
	if(component === 'bespokedata'){
		myAwesomeApp,bespokecomponent.init();
	};
};
myAwesomeApp.components.bespokecomponent = {
	url:'bespoke.js',
	loaded:false
};
myAwesomeApp.components.bespokelabels = {
	url:'bespokelabels.js',
	loaded:false
};
myAwesomeApp.components.bespokedata = {
	url:'bespokedata.js',
	loaded:false
};
myAwesomeApp.addComponent('bespokecomponent');

Following this practice you can write pretty complex apps and still have full control over what is available when. You can also extend this to allow for CSS files to be added on demand.

153,JavaScript Internationalisation,"or:  Why Rudolph Is More Than Just a Shiny Nose

Dunder sat, glumly staring at the computer screen.

“What’s up, Dunder?” asked Rudolph, entering the stable and shaking off the snow from his antlers.

“Well,” Dunder replied, “I’ve just finished coding the new reindeer intranet Santa Claus asked me to do. You know how he likes to appear to be at the cutting edge, talking incessantly about Web 2.0, AJAX, rounded corners; he even spooked Comet recently by talking about him as if he were some pushy web server.

“I’ve managed to keep him happy, whilst also keeping it usable, accessible, and gleaming — and I’m still on the back row of the sleigh! But anyway, given the elves will be the ones using the site, and they come from all over the world, the site is in multiple languages. Which is great, except when it comes to the preview JavaScript I’ve written for the reindeer order form. Here, have a look…”

As he said that, he brought up the textileRef:8234272265470b85d91702:linkStartMarker:“order
    form in French”:/examples/javascript-internationalisation/initial.fr.html on the screen. (Same in English).

“Looks good,” said Rudolph.

“But if I add some items,” said Dunder, “the preview appears in English, as it’s hard-coded in the JavaScript. I don’t want separate code for each language, as that’s just silly — I thought about just having if statements, but that doesn’t scale at all…”

“And there’s more, you aren’t displaying large numbers in French properly, either,” added Rudolph, who had been playing and looking at part of the source code:

function update_text() {
	var hay = getValue('hay');
	var carrots = getValue('carrots');
	var bells = getValue('bells');
	var total = 50 * bells + 30 * hay + 10 * carrots;
	var out = 'You are ordering '
		+ pretty_num(hay) + ' bushel' + pluralise(hay) + ' of hay, '
		+ pretty_num(carrots) + ' carrot' + pluralise(carrots)
		+ ', and ' + pretty_num(bells) + ' shiny bell' + pluralise(bells)
		+ ', at a total cost of <strong>' + pretty_num(total)
		+ '</strong> gold pieces. Thank you.';
	document.getElementById('preview').innerHTML = out;
}
function pretty_num(n) {
	n += '';
	var o = '';
	for (i=n.length; i>3; i-=3) {
		o = ',' + n.slice(i-3, i) + o;
	}
	o = n.slice(0, i) + o;
	return o;
}
function pluralise(n) {
	if (n!=1) return 's';
	return '';
}

“Oh, botheration!” cried Dunder. “This is just so complicated.”

“It doesn’t have to be,” said Rudolph, “you just have to think about things in a slightly different way from what you’re used to. As we’re only a simple example, we won’t be able to cover all possibilities, but for starters, we need some way of providing different information to the script dependent on the language. We’ll create a global i18n object, say, and fill it with the correct language information. The first variable we’ll need will be a thousands separator, and then we can change the pretty_num function to use that instead:

function pretty_num(n) {
	n += '';
	var o = '';
	for (i=n.length; i>3; i-=3) {
		o = i18n.thousands_sep + n.slice(i-3, i) + o;
	}
	o = n.slice(0, i) + o;
	return o;
}

“The i18n object will also contain our translations, which we will access through a function called _() — that’s just an underscore. Other languages have a function of the same name doing the same thing. It’s very simple:

function _(s) {
	if (typeof(i18n)!='undefined' && i18n[s]) {
		return i18n[s];
	}
	return s;
}

“So if a translation is available and provided, we’ll use that; otherwise we’ll default to the string provided — which is helpful if the translation begins to lag behind the site’s text at all, as at least something will be output.”

“Got it,” said Dunder. “ _('Hello Dunder') will print the translation of that string, if one exists, ‘Hello Dunder’ if not.”

“Exactly. Moving on, your plural function breaks even in English if we have a word where the plural doesn’t add an s — like ‘children’.”

“You’re right,” said Dunder. “How did I miss that?”

“No harm done. Better to provide both singular and plural words to the function and let it decide which to use, performing any translation as well:

function pluralise(s, p, n) {
	if (n != 1) return _(p);
	return _(s);
}

“We’d have to provide different functions for different languages as we employed more elves and got more complicated — for example, in Polish, the word ‘file’ pluralises like this: 1 plik, 2-4 pliki, 5-21 plików, 22-24 pliki, 25-31 plików, and so on.” (More information on plural forms)

“Gosh!”

“Next, as different languages have different word orders, we must stop using concatenation to construct sentences, as it would be impossible for other languages to fit in; we have to keep coherent strings together. Let’s rewrite your update function, and then go through it:

function update_text() {
	var hay = getValue('hay');
	var carrots = getValue('carrots');
	var bells = getValue('bells');
	var total = 50 * bells + 30 * hay + 10 * carrots;
	hay = sprintf(pluralise('%s bushel of hay', '%s bushels of hay', hay), pretty_num(hay));
	carrots = sprintf(pluralise('%s carrot', '%s carrots', carrots), pretty_num(carrots));
	bells = sprintf(pluralise('%s shiny bell', '%s shiny bells', bells), pretty_num(bells));
	var list = sprintf(_('%s, %s, and %s'), hay, carrots, bells);
	var out = sprintf(_('You are ordering %s, at a total cost of <strong>%s</strong> gold pieces.'),
		list, pretty_num(total));
	out += ' ';
	out += _('Thank you.');
	document.getElementById('preview').innerHTML = out;
}

“ sprintf is a function in many other languages that, given a format string and some variables, slots the variables into place within the string. JavaScript doesn’t have such a function, so we’ll write our own. Again, keep it simple for now, only integers and strings; I’m sure more complete ones can be found on the internet.

function sprintf(s) {
	var bits = s.split('%');
	var out = bits[0];
	var re = /^([ds])(.*)$/;
	for (var i=1; i<bits.length; i++) {
		p = re.exec(bits[i]);
		if (!p || arguments[i]==null) continue;
		if (p[1] == 'd') {
			out += parseInt(arguments[i], 10);
		} else if (p[1] == 's') {
			out += arguments[i];
		}
		out += p[2];
	}
	return out;
}

“Lastly, we need to create one file for each language, containing our i18n object, and then include that from the relevant HTML. Here’s what a blank translation file would look like for your order form:

var i18n = {
	thousands_sep: ',',
	""%s bushel of hay"": '',
	""%s bushels of hay"": '',
	""%s carrot"": '',
	""%s carrots"": '',
	""%s shiny bell"": '',
	""%s shiny bells"": '',
	""%s, %s, and %s"": '',
	""You are ordering %s, at a total cost of <strong>%s</strong> gold pieces."": '',
	""Thank you."": ''
};

“If you implement this across the intranet, you’ll want to investigate the xgettext program, which can automatically extract all strings that need translating from all sorts of code files into a standard .po file (I think Python mode works best for JavaScript). You can then use a different program to take the translated .po file and automatically create the language-specific JavaScript files for us.” (e.g. German .po file for PledgeBank, mySociety’s .po-.js script, example output)

With a flourish, Rudolph finished editing. “And there we go, localised JavaScript in English, French, or German, all using the same main code.”

“Thanks so much, Rudolph!” said Dunder.

“I’m not just a pretty nose!” Rudolph quipped. “Oh, and one last thing — please comment liberally explaining the context of strings you use. Your translator will thank you, probably at the same time as they point out the four hundred places you’ve done something in code that only works in your language and no-one else’s…”

Thanks to Tim Morley and Edmund Grimley Evans for the French and German translations respectively.",2007,Matthew Somerville,matthewsomerville,2007-12-08T00:00:00+00:00,https://24ways.org/2007/javascript-internationalisation/,code
146,Increase Your Font Stacks With Font Matrix,"Web pages built in plain old HTML and CSS are displayed using only the fonts installed on users’ computers (@font-face implementations excepted). To enable this, CSS provides the font-family property for specifying fonts in order of preference (often known as a font stack). For example:

h1 {font-family: 'Egyptienne F', Cambria, Georgia, serif}

So in the above rule, headings will be displayed in Egyptienne F. If Egyptienne F is not available then Cambria will be used, failing that Georgia or the final fallback default serif font. This everyday bit of CSS will be common knowledge among all 24 ways readers.

It is also a commonly held belief that the only fonts we can rely on being installed on users’ computers are the core web fonts of Arial, Times New Roman, Verdana, Georgia and friends. But is that really true?

If you look in the fonts folder of your computer, or even your Mum’s computer, then you are likely to find a whole load of fonts besides the core ones. This is because many software packages automatically install extra typefaces. For example, Office 2003 installs over 100 additional fonts. Admittedly not all of these fonts are particularly refined, and not all are suitable for the Web. However they still do increase your options. 

The Matrix

I have put together a matrix of (western) fonts showing which are installed with Mac and Windows operating systems, which are installed with various versions of Microsoft Office, and which are installed with Adobe Creative Suite.



The matrix is available for download as an Excel file and as a CSV.  There are no readily available statistics regarding the penetration of Office or Creative Suite, but you can probably take an educated guess based on your knowledge of your readers.

The idea of the matrix is that use can use it to help construct your font stack. First of all pick the font you’d really like for your text – this doesn’t have to be in the matrix. Then pick the generic family (serif, sans-serif, cursive, fantasy or monospace) and a font from each of the operating systems. Then pick any suitable fonts from the Office and Creative Suite lists.

For example, you may decide your headings should be in the increasingly ubiquitous Clarendon. This is a serif type face. At OS-level the most similar is arguably Georgia. Adobe CS2 comes with Century Old Style which has a similar feel. Century Schoolbook is similar too, and is installed with all versions of Office. Based on this your font stack becomes:

font-family: 'Clarendon Std', 'Century Old Style Std', 'Century Schoolbook', Georgia, serif






Note the ‘Std’ suffix indicating a ‘standard’ OpenType file, which will normally be your best bet for more esoteric fonts.

I’m not suggesting the process of choosing suitable fonts is an easy one. Firstly there are nearly two hundred fonts in the matrix, so learning what each font looks like is tricky and potentially time consuming (if you haven’t got all the fonts installed on a machine to hand you’ll be doing a lot of Googling for previews). And it’s not just as simple as choosing fonts that look similar or have related typographic backgrounds, they need to have similar metrics as well, This is especially true in terms of x-height which gives an indication of how big or small a font looks.

Over to You

The main point of all this is that there are potentially more fonts to consider than is generally accepted, so branch out a little (carefully and tastefully) and bring a little variety to sites out there. If you come up with any novel font stacks based on this approach, please do blog them (tagged as per the footer) and at some point they could all be combined in one place for everyone to consider.

Appendix

What about Linux?

The only operating systems in the matrix are those from Microsoft and Apple. For completeness, Linux operating systems should be included too, although these are many and varied and very much in a minority, so I omitted them for time being. For the record, some Linux distributions come packaged with Microsoft’s core fonts. Others use the Vera family, and others use the Liberation family which comprises fonts metrically identical to Times New Roman and Arial.

159,How Media Studies Can Massage Your Message,"A young web designer once told his teacher ‘just get to the meat already.’ He was frustrated with what he called the ‘history lessons and name-dropping’ aspects of his formal college course. He just wanted to learn how to build Web sites, not examine the reasons why.

Technique and theory are both integrated and necessary portions of a strong education. The student’s perspective has direct value, but also holds a distinct sorrow: Knowing the how without the why creates a serious problem. Without these surrounding insights we cannot tap into the influence of the history and evolved knowledge that came before. We cannot properly analyze, criticize, evaluate and innovate beyond the scope of technique.

History holds the key to transcending former mistakes. Philosophy encourages us to look at different points of view. Studying media and social history empowers us as Web workers by bringing together myriad aspects of humanity in direct relation to the environment of society and technology. Having an understanding of media, communities, communication arts as well as logic, language and computer savvy are all core skills of the best of web designers in today’s medium.

Controlling the Message


	‘The computer can’t tell you the emotional story. It can give you the exact mathematical design, but what’s missing is the eyebrows.’ – Frank Zappa


Media is meant to express an idea. The great media theorist Marshall McLuhan suggests that not only is media interesting because it’s about the expression of ideas, but that the media itself actually shapes the way a given idea is perceived.  This is what McLuhan meant when he uttered those famous words: ‘The medium is the message.’

If instead of actually serving a steak to a vegetarian friend, what might a painting of the steak mean instead? Or a sculpture of a cow? Depending upon the form of media in question, the message is altered.

Figure 1

Must we know the history of cows to appreciate the steak on our plate? Perhaps not, but if we begin to examine how that meat came to be on the plate, the social, cultural and ideological associations of that cow, we begin to understand the complexity of both medium and message. A piece of steak on my plate makes me happy. A vegetarian friend from India might disagree and even find that that serving her a steak was very insensitive.

Takeaway: Getting the message right involves understanding that message in order to direct it to your audience accordingly.

A Separate Piece

If we revisit the student who only wants technique, while he might become extremely adept at the rendering of an idea, without an understanding of the medium, how is he to have greater control over how that idea is perceived?  Ultimately, his creativity is limited and his perspective narrowed, and the teacher has done her student a disservice without challenging him, particularly in a scholastic environment, to think in liberal, creative and ultimately innovative terms.

For many years, web pundits including myself have promoted the idea of separation as a core concept within creating effective front-end media for the Web. By this, we’ve meant literal separation of the technologies and documents: Markup for content; CSS for presentation; DOM Scripting for behavior. While the message of separation was an important part of understanding and teaching best practices for manageable, scalable sites, that separation is really just a separation of pieces, not of entire disciplines.

For in fact, the medium of the Web is an integrated one. That means each part of the desired message must be supported by the media silos within a given site.  The visual designer must study the color, space, shape and placement of visual objects (including type) into a meaningful expression. The underlying markup is ideally written as semantically as possible, promote the meaning of the content it describes. Any interaction and functionality must make the process of the medium support, not take away from, the meaning of the site or Web application.  

Examination: The Glass Bead Game

Figure 2

Figure 2 shows two screenshots of CoreWave’s historic ‘Glass Bead Game.’ Fashioned after Herman Hesse’s novel of the same name, the game was an exploration of how ideas are connected to other ideas via multiple forms of media. It was created for the Web in 1996 using server-side randomization with .htmlx files in order to allow players to see how random associations are in fact not random at all.

Takeaway: We can use the medium itself to explore creative ideas, to link us from one idea to the next, and to help us better express those ideas to our audiences.

Computers and Human Interaction

Since our medium involves computers and human interaction, it does us well to look to foundations of computers and reason. Not long ago I was chatting with Jared Spool on IM about this and that, and he asked me ‘So how do you feel about that?’ This caused me no end of laughter and I instantly quipped back ‘It’s okay by me ELIZA.’ We both enjoyed the joke, but then I tried to share it with another dare I say younger colleague, and the reference was lost.

Raise your hand if you got the reference! Some of you will, but many people who come to the Web medium do not get the benefit of such historical references because we are not formally educated in them. Joseph Weizenbaum created the ELIZA program, which emulates a Rogerian Therapist, in 1966. It was an early study of computers and natural human language. I was a little over 2 years old, how about you?

Conversation with Eliza

There are fortunately a number of ELIZA emulators on the Web. I found one at http://www.chayden.net/eliza/Eliza.html that actually contains the source code (in Java) that makes up the ELIZA script.

Figure 3 shows a screen shot of the interaction. ELIZA first welcomes me, says ‘Hello, How do you do. Please state your problem’ and we continue in a short loop of conversation, the computer using cues from my answers to create new questions and leading fragments of conversation.

Figure 3

Albeit a very limited demonstration of how humans could interact with a computer in 1966, it’s amusing to play with now and compare it to something as richly interactive as the Microsoft Surface (Figure 4). Here, we see clear Lucite blocks that display projected video. Each side of the block has a different view of the video, so not only does one have to match up the images as they are moving, but do so in the proper directionality.

Figure 4

Takeway: the better we know our environment, the more we can alter it to emulate, expand and even supersede our message.

Leveraging Holiday Cheer

Since most of us at least have a few days off for the holidays now that Christmas is upon us, now’s a perfect time to reflect on ones’ environment and examine the messages within it. Convince your spouse to find you a few audio books for stocking stuffers. Find interactive games to play with your kids and observe them, and yourself, during the interaction. Pour a nice egg-nog and sit down with a copy of Marshall McLuhan’s ‘The Medium is the Massage.’ Leverage that holiday cheer and here’s to a prosperous, interactive new year.",2007,Molly Holzschlag,mollyholzschlag,2007-12-22T00:00:00+00:00,https://24ways.org/2007/how-media-studies-can-massage-your-message/,ux
163,Get To Grips with Slippy Maps,"Online mapping has definitely hit mainstream. Google Maps made ‘slippy maps’ popular and made it easy for any developer to quickly add a dynamic map to his or her website. You can now find maps for store locations, friends nearby, upcoming events, and embedded in blogs. 

In this tutorial we’ll show you how to easily add a map to your site using the Mapstraction mapping library. There are many map providers available to choose from, each with slightly different functionality, design, and terms of service. Mapstraction makes deciding which provider to use easy by allowing you to write your mapping code once, and then easily switch providers.

Assemble the pieces

Utilizing any of the mapping library typically consists of similar overall steps:


	Create an HTML div to hold the map
	Include the Javascript libraries
	Create the Javascript Map element
	Set the initial map center and zoom level
	Add markers, lines, overlays and more


Create the Map Div

The HTML div is where the map will actually show up on your page. It needs to have a unique id, because we’ll refer to that later to actually put the map here. This also lets you have multiple maps on a page, by creating individual divs and Javascript map elements. The size of the div also sets the height and width of the map. You set the size using CSS, either inline with the element, or via a CSS reference to the element id or class. For this example, we’ll use inline styling.

<div id=""map"" style=""width: 400px; height: 400px;""></div>

Include Javascript libraries

A mapping library is like any Javascript library. You need to include the library in your page before you use the methods of that library. For our tutorial, we’ll need to include at least two libraries: Mapstraction, and the mapping API(s) we want to display. Our first example we’ll use the ubiquitous Google Maps library. However, you can just as easily include Yahoo, MapQuest, or any of the other supported libraries.

Another important aspect of the mapping libraries is that many of them require an API key. You will need to agree to the terms of service, and get an API key these.

<script src=""http://maps.google.com/maps?file=api&v=2&key=YOUR_KEY"" type=""text/javascript""></script>
<script type=""text/javascript"" src=""http://mapstraction.com/src/mapstraction.js""></script>

Create the Map

Great, we’ve now put in all the pieces we need to start actually creating our map. This is as simple as creating a new Mapstraction object with the id of the HTML div we created earlier, and the name of the mapping provider we want to use for this map. 

With several of the mapping libraries you will need to set the map center and zoom level before the map will appear. The map centering actually triggers the initialization of the map. 

var mapstraction = new Mapstraction('map','google');
var myPoint = new LatLonPoint(37.404,-122.008);
mapstraction.setCenterAndZoom(myPoint, 10);

A note about zoom levels. The setCenterAndZoom function takes two parameters, the center as a LatLonPoint, and a zoom level that has been defined by mapping libraries. The current usage is for zoom level 1 to be “zoomed out”, or view the entire earth – and increasing the zoom level as you zoom in. Typically 17 is the maximum zoom, which is about the size of a house. 

Different mapping providers have different quality of zoomed in maps over different parts of the world. This is a perfect reason why using a library like Mapstraction is very useful, because you can quickly change mapping providers to accommodate users in areas that have bad coverage with some maps. 

To switch providers, you just need to include the Javascript library, and then change the second parameter in the Mapstraction creation. Or, you can call the switch method to dynamically switch the provider.

So for Yahoo Maps  (demo):

var mapstraction = new Mapstraction('map','yahoo');

or Microsoft Maps (demo):

var mapstraction = new Mapstraction('map','microsoft');

want a 3D globe in your browser? try FreeEarth (demo):

var mapstraction = new Mapstraction('map','freeearth');

or even OpenStreetMap (free your data!)  (demo):

var mapstraction = new Mapstraction('map','openstreetmap');

Visit the Mapstraction multiple map demo page for an example of how easy it is to have many maps on your page, each with a different provider. 

Adding Markers

While adding your first map is fun, and you can probably spend hours just sliding around, the point of adding a map to your site is usually to show the location of something. So now you want to add some markers. There are a couple of ways to add to your map.

The simplest is directly creating markers. You could either hard code this into a rather static page, or dynamically generate these using whatever tools your site is built on.

var marker = new Marker( new LatLonPoint(37.404,-122.008) );
marker.setInfoBubble(""It's easy to add maps to your site"");
mapstraction.addMarker( marker );

There is a lot more you can do with markers, including changing the icon, adding timestamps, automatically opening the bubble, or making them draggable. 

While it is straight-forward to create markers one by one, there is a much easier way to create a large set of markers. And chances are, you can make it very easy by extending some data you already are sharing: RSS. 

Specifically, using GeoRSS you can easily add a large set of markers directly to a map. GeoRSS is a community built standard (like Microformats) that added geographic markup to RSS and Atom entries. It’s as simple as adding <georss:point>42 -83</georss:point> to your feeds to share items via GeoRSS. Once you’ve done that, you can add that feed as an ‘overlay’ to your map using the function:

mapstraction.addOverlay(""http://api.flickr.com/services/feeds/groups_pool.gne?id=322338@N20&format=rss_200&georss=1"");

Mapstraction also supports KML for many of the mapping providers. So it’s easy to add various data sources together with your own data. Check out Mapufacture for a growing index of available GeoRSS feeds and KML documents. 

Play with your new toys

Mapstraction offers a lot more functionality you can utilize for demonstrating a lot of geographic data on your website. It also includes geocoding and routing abstraction layers for making sure your users know where to go.

151,Get In Shape,"Pop quiz: what’s wrong with the following navigation?



Maybe nothing. But then again, maybe there’s something bugging you about the way it comes together, something you can’t quite put your finger on. It seems well-designed, but it also seems a little… off.

The design decisions that led to this eventual form were no doubt well-considered:


	Client: The top level needs to have a “current page” status indicator of some sort.
	Designer: How about a white tab?
	Client: Great! The second level needs to show up underneath the first level though…
	Designer: Okay, but that white tab I just added makes it hard to visually connect the bottom nav to the top.
	Client: Too late, we’ve seen the white tab and we love it. Try and make it work.
	Designer: Right. So I placed the second level in its own box.
	Client: Hmm. They seem too separated. I can’t tell that the yellow nav is the second level of the first.
	Designer: How about an indicator arrow?
	Client: Brilliant!


The problem is that the end result feels awkward and forced. During the design process, little decisions were made that ultimately affect the overall shape of the navigation. What started out as a neatly contained rounded rectangle ended up as an ambiguous double shape that looks funny, though it’s often hard to pinpoint precisely why.

The Shape of Things

Well the why in this case is because seemingly unrelated elements in a design still end up visually interacting. Adding a new item to a page impacts everything surrounding it. In this navigation example, we’re looking at two individual objects that are close enough to each other that they form a relationship; if we reduce them to strictly their outlines, it’s a little easier to see that this particular combination registers oddly.



The two shapes float with nothing really grounding them. If they were connected, perhaps it would be a different story. The white tab divides the top shape in half, leaving a gap in the middle of it. There’s very little balance in this pairing because the overall shape of the navigation wasn’t considered during the design process.

Here’s another example: Gmail. Great email client, but did you ever closely look at what’s going on in that left hand navigation? The continuous blue bar around the message area spills out into the navigation. If we remove all text, we’re left with this odd configuration:



Though the reasoning for anchoring the navigation highlight against the message area might be sound, the result is an irregular shape that doesn’t correspond with anything in reality. You may never consciously notice it, but once you do it’s hard to miss. One other example courtesy of last.fm:



The two header areas are the same shade of pink so they appear to be closely connected. When reduced to their outlines it’s easy to see that this combination is off-balance: the edges don’t align, the sharp corners of the top shape aren’t consistent with the rounded corners of the bottom, and the part jutting out on the right of the bottom one seems fairly random. The result is a duo of oddly mis-matched shapes.

Design Strategies

Our minds tend to pick out familiar patterns. A clever designer can exploit this by creating references in his or her work to shapes and combinations with which viewers are already familiar. There are a few simple ideas that can be employed to help you achieve this: consistency, balance, and completion.

Consistency

A fairly simple way to unify the various disparate shapes on a page is by designing them with a certain amount of internal consistency. You don’t need to apply an identical size, colour, border, or corner treatment to every single shape; devolving a design into boring repetition isn’t what we’re after here. But it certainly doesn’t hurt to apply a set of common rules to most shapes within your work.



Consider purevolume and its multiple rounded-corner panels. From the bottom of the site’s main navigation to the grey “Extras” panels halfway down the page (shown above), multiple shapes use a common border radius for unity. Different colours, different sizes, different content, but the consistent outlines create a strong sense of similarity. Not that every shape on the site follows this rule; they break the pattern right at the top with a darker sharp-cornered header, and again with the thumbnails below. But the design remains unified, nonetheless.

Balance

Arguably the biggest problem with the last.fm example earlier is one of balance. The area poking out of the bottom shape created a fairly obvious imbalance for no apparent reason. The right hand side is visually emphasized due to the greater area of pink coverage, but with the white gap left beside it, the emphasis seems unwarranted. It’s possible to create tension in your design by mismatching shapes and throwing off the balance, but when that happens unintentionally it can look like a mistake.



Above are a few examples of design elements in balanced and unbalanced configurations. The examples in the top row are undeniably more pleasing to the eye than those in the bottom row. If these were fleshed out into full designs, those derived from the templates in the top row would naturally result in stronger work.

Take a look at the header on 9Rules for a study in well-considered balance. On the left you’ll see a couple of paragraphs of text, on the right you have floating navigational items, and both flank the site’s logo. This unusual layout combines multiple design elements that look nothing alike, and places them together in a way that anchors each so that no one weighs down the header.

Completion

And finally we come to the idea of completion. Shapes don’t necessarily need hard outlines to be read visually as shapes, which can be exploited for various purposes. Notice how Zend’s mid-page “Business Topics” and “News” items (below) fade out to the right and bottom, but the placement of two of these side-by-side creates an impression of two panels rather than three disparate floating columns. By allowing the viewer’s eye to complete the shapes, they’ve lightened up the design of the page and removed inessential lines. In a busy design this technique could prove quite handy.



Along the same lines, the individual shapes within your design may also be combined visually to form outlines of larger shapes. The differently-coloured header and main content/sidebar shapes on Veerle’s blog come together to form a single central panel, further emphasized by the slight drop shadow to the right.

Implementation

Studying how shape can be used effectively in design is simply a starting point. As with all things design-related, there are no hard and fast rules here; ultimately you may choose to bring these principles into your work more often, or break them for effect. But understanding how shapes interact within a page, and how that effect is ultimately perceived by viewers, is a key design principle you can use to impress your friends.",2007,Dave Shea,daveshea,2007-12-16T00:00:00+00:00,https://24ways.org/2007/get-in-shape/,design
154,Diagnostic Styling,"We’re all used to using CSS to make our designs live and breathe, but there’s another way to use CSS: to find out where our markup might be choking on missing accessibility features, targetless links, and just plain missing content.  

Note: the techniques discussed here mostly work in Firefox, Safari, and Opera, but not Internet Explorer.  I’ll explain why that’s not really a problem near the end of the article — and no, the reason is not “everyone should just ignore IE anyway”.

Basic Diagnostics

To pick a simple example, suppose you want to call out all holdover font and center elements in a site.  Simple: you just add the following to your styles.

font, center {outline: 5px solid red;}

You could take it further and add in a nice lime background or some such, but big thick red outlines should suffice.  Now you’ll be able to see the offenders wherever as you move through the site.  (Of course, if you do this on your public server, everyone else will see the outlines too.  So this is probably best done on a development server or local copy of the site.)

Not everyone may be familiar with outlines, which were introduced in CSS2, so a word on those before we move on.  Outlines are much like borders, except outlines don’t affect layout.  Eh?  Here’s a comparison.



On the left, you have a border.  On the right, an outline.  The border takes up layout space, pushing other content around and generally being a nuisance.  The outline, on the other hand, just draws into quietly into place.  In most current browsers, it will overdraw any content already onscreen, and will be overdrawn by any content placed later — which is why it overlaps the images above it, and is overlapped by those below it.

Okay, so we can outline deprecated elements like font and center.  Is that all?  Oh no.

Attribution

Let’s suppose you also want to find any instances of inline style — that is, use of the style attribute on elements in the markup.  This is generally discouraged (outside of HTML e-mails, which I’m not going to get anywhere near), as it’s just another side of the same coin of using font: baking the presentation into the document structure instead of putting it somewhere more manageable.  So:

*[style], font, center {outline: 5px solid red;}

Adding that attribute selector to the rule’s grouped selector means that we’ll now be outlining any element with a style attribute.

There’s a lot more that attribute selectors will let use diagnose.  For example, we can highlight any images that have empty alt or title text.

img[alt=""""] {border: 3px dotted red;}
img[title=""""] {outline: 3px dotted fuchsia;}

Now, you may wonder why one of these rules calls for a border, and the other for an outline.  That’s because I want them to “add together” — that is, if I have an image which possesses both alt and title, and the values of both are empty, then I want it to be doubly marked.



See how the middle image there has both red and fuchsia dots running around it?  (And am I the only one who sorely misses the actual circular dots drawn by IE5/Mac?)  That’s due to its markup, which we can see here in a fragment showing the whole table row.

<tr>
<th scope=""row"">empty title</th>
<td><img src=""comic.gif"" title="""" /></td>
<td><img src=""comic.gif"" title="""" alt="""" /></td>
<td><img src=""comic.gif"" title="""" alt=""comical"" /></td>
</tr>

Right, that’s all well and good, but it misses a rather more serious situation: the selector img[alt=""""] won’t match an img element that doesn’t even have an alt attribute.  How to tackle this problem?

Not a Problem

Well, if you want to select something based on a negative, you need a negative selector.

img:not([alt]) {border: 5px solid red;}

This is really quite a break from the rest of CSS selection, which is all positive: “select anything that has these characteristics”.  With :not(), we have the ability to say (in supporting browsers) “select anything that hasn’t these characteristics”.  In the above example, only img elements that do not have an alt attribute will be selected.  So we expand our list of image-related rules to read:

img[alt=""""] {border: 3px dotted red;}
img[title=""""] {outline: 3px dotted fuchsia;}
img:not([alt]) {border: 5px solid red;}
img:not([title]) {outline: 5px solid fuchsia;}

With the following results:



We could expand this general idea to pick up tables who lack a summary, or have an empty summary attribute.

table[summary=""""] {outline: 3px dotted red;}
table:not([summary]) {outline: 5px solid red;}

When it comes to selecting header cells that lack the proper scope, however, we have a trickier situation.  Finding headers with no scope attribute is easy enough, but what about those that have a scope attribute with an incorrect value?

In this case, we actually need to pull an on-off maneuver.  This has us setting all th elements to have a highlight style, and then turn it off for the elements that meet our criteria.

th {border: 2px solid red;}
th[scope=""col""], th[scope=""row""] {border: none;}

This was necessary because of the way CSS selectors work.  For example, consider this:

th:not([scope=""col""]), th:not([scope=""row""]) {border: 2px solid red;}

That would select…all th elements, regardless of their attrributes.  That’s because every th element doesn’t have a scope of col, doesn’t have a scope of row, or doesn’t have either.  There’s no escaping this selector o’ doom!

This limitation arises because :not() is limited to containing a single “thing” within its parentheses.  You can’t, for example, say “select all elements except those that are images which descend from list items”.  Reportedly, this limitation was imposed to make browser implementation of :not() easier.

Still, we can make good use of :not() in the service of further diagnosing.  Calling out links in trouble is a breeze:

a[href]:not([title]) {border: 5px solid red;}
a[title=""""] {outline: 3px dotted red;}
a[href=""#""] {background: lime;}
a[href=""""] {background: fuchsia;}



Here we have a set that will call our attention to links missing title information, as well as links that have no valid target, whether through a missing URL or a JavaScript-driven page where there are no link fallbacks in the case of missing or disabled JavaScript (href=""#"").

And What About IE?

As I said at the beginning, much of what I covered here doesn’t work in Internet Explorer, most particularly :not() and outline.  (Oh, so basically everything?  -Ed.)

I can’t do much about the latter.  For the former, however, it’s possible to hack your way around the problem by doing some layered on-off stuff.  For example, for images, you replace the previously-shown rules with the following:

img {border: 5px solid red;}
img[alt][title] {border-width: 0;}
img[alt] {border-color: fuchsia;}
img[alt], img[title] {border-style: double;}
img[alt=""""][title],
img[alt][title=""""] {border-width: 3px;}
img[alt=""""][title=""""] {border-style: dotted;}

It won’t have exactly the same set of effects, given the inability to use both borders and outlines, but will still highlight troublesome images.



It’s also the case that IE6 and earlier lack support for even attribute selectors, whereas IE7 added pretty much all the attribute selector types there are, so the previous code block won’t have any effect previous to IE7.

In a broader sense, though, these kinds of styles probably aren’t going to be used in the wild, as it were.  Diagnostic styles are something only you see as you work on a site, so you can make sure to use a browser that supports outlines and :not() when you’re diagnosing.  The fact that IE users won’t see these styles is irrelevant since users of any browser probably won’t be seeing these styles.

Personally, I always develop in Firefox anyway, thanks to its ability to become a full-featured IDE through the addition of extensions like Firebug and the Web Developer Toolbar.


Yeah, About That…

It’s true that much of what I describe in this article is available in the WDT.  I feel there are two advantages to writing your own set of diagnostic styles.


	When you write your own styles, you can define exactly what the visual results will be, and how they will interact.  The WDT doesn’t let you make its outlines thicker or change their colors.
	You can combine a bunch of diagnostics into a single set of rules and add it to your site’s style sheet during the diagnostic portion, thus ensuring they persist as you surf around.  This can be done in the WDT, but it isn’t as easy (and, at least for me, not as reliable).


It’s also true that a markup validator will catch many of the errors I mentioned, such as missing alt and summary attributes.  For some, that’s sufficient.  But it won’t catch everything diagnostic styles can, like empty alt values or untargeted links, which are perfectly valid, syntactically speaking.


Diagnosis Complete?

I hope this has been a fun look at the concept of diagnostic styling as well as a quick introduction into possibly new concepts like :not() and outlines.  This isn’t all there is to say, of course: there is plenty more that could be added to a diagnostic style sheet.  And everyone’s diagnostics will be different, tuned to meet each person’s unique situation.

Mostly, though, I hope this small exploration triggers some creative thinking about the use of CSS to do more than just lay out pages and colorize text.  Given the familiarity we acquire with CSS, it only makes sense to use it wherever it might be useful, and setting up visible diagnostic flags is just one more place for it to help us.",2007,Eric Meyer,ericmeyer,2007-12-20T00:00:00+00:00,https://24ways.org/2007/diagnostic-styling/,process
152,CSS for Accessibility,"CSS is magical stuff. In the right hands, it can transform the plainest of (well-structured) documents into a visual feast. But it’s not all fur coat and nae knickers (as my granny used to say). Here are some simple ways you can use CSS to improve the usability and accessibility of your site. 

Even better, no sexy visuals will be harmed by the use of these techniques. Promise.

Nae knickers

This is less of an accessibility tip, and more of a reminder to check that you’ve got your body background colour specified.

If you’re sitting there wondering why I’m mentioning this, because it’s a really basic thing, then you might be as surprised as I was to discover that from a sample of over 200 sites checked last year, 35% of UK local authority websites were missing their body background colour.

Forgetting to specify your body background colour can lead to embarrassing gaps in coverage, which are not only unsightly, but can prevent your users reading the text on your site if they use a different operating system colour scheme.

All it needs is the following line to be added to your CSS file:

body {background-color: #fff;}

If you pair it with 

color: #000;

… you’ll be assured of maintaining contrast for any areas you inadvertently forget to specify, no matter what colour scheme your user needs or prefers.

Even better, if you’ve got standard reset CSS you use, make sure that default colours for background and text are specified in it, so you’ll never be caught with your pants down. At the very least, you’ll have a white background and black text that’ll prompt you to change them to your chosen colours.

Elbow room

Paying attention to your typography is important, but it’s not just about making it look nice. 

Careful use of the line-height property can make your text more readable, which helps everyone, but is particularly helpful for those with dyslexia, who use screen magnification or simply find it uncomfortable to read lots of text online. 

When lines of text are too close together, it can cause the eye to skip down lines when reading, making it difficult to keep track of what you’re reading across. 

So, a bit of room is good.

That said, when lines of text are too far apart, it can be just as bad, because the eye has to jump to find the next line. That not only breaks up the reading rhythm, but can make it much more difficult for those using Screen Magnification (especially at high levels of magnification) to find the beginning of the next line which follows on from the end of the line they’ve just read.

Using a line height of between 1.2 and 1.6 times normal can improve readability, and using unit-less line heights help take care of any pesky browser calculation problems.

For example: 

p {
	font-family: ""Lucida Grande"", Lucida, Verdana, Helvetica, sans-serif;
	font-size: 1em;
	line-height: 1.3;
}

or if you want to use the shorthand version:

p {
	font: 1em/1.3 ""Lucida Grande"", Lucida, Verdana, Helvetica, sans-serif;
}

View some examples of different line-heights, based on default text size of 100%/1em.

Further reading on Unitless line-heights from Eric Meyer.

Transformers: Initial case in disguise

Nobody wants to shout at their users, but there are some occasions when you might legitimately want to use uppercase on your site.

Avoid screen-reader pronunciation weirdness (where, for example, CONTACT US would be read out as Contact U S, which is not the same thing – unless you really are offering your users the chance to contact the United States) caused by using uppercase by using title case for your text and using the often neglected text-transform property to fake uppercase.

For example:

.uppercase {
	text-transform: uppercase
}    

Don’t overdo it though, as uppercase text is harder to read than normal text, not to mention the whole SHOUTING thing.

Linky love

When it comes to accessibility, keyboard only users (which includes those who use voice recognition software) who can see just fine are often forgotten about in favour of screen reader users.

This Christmas, share the accessibility love and light up those links so all of your users can easily find their way around your site.

The link outline

AKA: the focus ring, or that dotted box that goes around links to show users where they are on the site.

The techniques below are intended to supplement this, not take the place of it. You may think it’s ugly and want to get rid of it, especially since you’re going to the effort of tarting up your links.

Don’t. 

Just don’t.

The non-underlined underline

If you listen to Jacob Nielsen, every link on your site should be underlined so users know it’s a link.

You might disagree with him on this (I know I do), but if you are choosing to go with underlined links, in whatever state, then remove the default underline and replacing it with a border that’s a couple of pixels away from the text. 

The underline is still there, but it’s no longer cutting off the bottom of letters with descenders (e.g., g and y) which makes it easier to read.

This is illustrated in Examples 1 and 2.

You can modify the three lines of code below to suit your own colour and border style preferences, and add it to whichever link state you like.

text-decoration: none;
border-bottom: 1px #000 solid;
padding-bottom: 2px;

Standing out from the crowd

Whatever way you choose to do it, you should be making sure your links stand out from the crowd of normal text which surrounds them when in their default state, and especially in their hover or focus states.

A good way of doing this is to reverse the colours when on hover or focus.

Well-focused

Everyone knows that you can use the :hover pseudo class to change the look of a link when you mouse over it, but, somewhat ironically, people who can see and use a mouse are the group who least need this extra visual clue, since the cursor handily (sorry) changes from an arrow to a hand.

So spare a thought for the non-pointing device users that visit your site and take the time to duplicate that hover look by using the :focus pseudo class.

Of course, the internets being what they are, it’s not quite that simple, and predictably, Internet Explorer is the culprit once more with it’s frustrating lack of support for :focus. Instead it applies the :active pseudo class whenever an anchor has focus.

What this means in practice is that if you want to make your links change on focus as well as on hover, you need to specify focus, hover and active.

Even better, since the look and feel necessarily has to be the same for the last three states, you can combine them into one rule.

So if you wanted to do a simple reverse of colours for a link, and put it together with the non-underline underlines from before, the code might look like this:

a:link {
	background: #fff;
	color: #000;
	font-weight: bold;
	text-decoration: none; 
	border-bottom: 1px #000 solid; 
	padding-bottom: 2px;
}
a:visited {
	background: #fff;
	color: #800080;
	font-weight: bold;
	text-decoration: none; 
	border-bottom: 1px #000 solid; 
	padding-bottom: 2px;
}
a:focus, a:hover, a:active {
	background: #000;
	color: #fff;
	font-weight: bold;
	text-decoration: none; 
	border-bottom: 1px #000 solid; 
	padding-bottom: 2px;
}

Example 3 shows what this looks like in practice.

Location, Location, Location

To take this example to it’s natural conclusion, you can add an id of current (or something similar) in appropriate places in your navigation, specify a full set of link styles for current, and have a navigation which, at a glance, lets users know which page or section they’re currently in.

Example navigation using location indicators.

and the source code

Conclusion

All the examples here are intended to illustrate the concepts, and should not be taken as the absolute best way to format links or style navigation bars – that’s up to you and whatever visual design you’re using at the time.

They’re also not the only things you should be doing to make your site accessible. 

Above all, remember that accessibility is for life, not just for Christmas.",2007,Ann McMeekin,annmcmeekin,2007-12-13T00:00:00+00:00,https://24ways.org/2007/css-for-accessibility/,design
162,Conditional Love,"“Browser.” The four-letter word of web design.

I mean, let’s face it: on the good days, when things just work in your target browsers, it’s marvelous. The air smells sweeter, birds’ songs sound more melodious, and both your design and your code are looking sharp.

But on the less-than-good days (which is, frankly, most of them), you’re compelled to tie up all your browsers in a sack, heave them into the nearest river, and start designing all-imagemap websites. We all play favorites, after all: some will swear by Firefox, Opera fans are allegedly legion, and others still will frown upon anything less than the latest WebKit nightly.

Thankfully, we do have an out for those little inconsistencies that crop up when dealing with cross-browser testing: CSS patches.

Spare the Rod, Hack the Browser

Before committing browsercide over some rendering bug, a designer will typically reach for a snippet of CSS fix the faulty browser. Historically referred to as “hacks,” I prefer Dan Cederholm’s more client-friendly alternative, “patches”.

But whatever you call them, CSS patches all work along the same principle: supply the proper property value to the good browsers, while giving higher maintenance other browsers an incorrect value that their frustrating idiosyncratic rendering engine can understand.

Traditionally, this has been done either by exploiting incomplete CSS support:

#content {
	height: 1%;	 // Let's force hasLayout for old versions of IE.
	line-height: 1.6;
	padding: 1em;
}
html>body #content {
	height: auto; // Modern browsers get a proper height value.
}

or by exploiting bugs in their rendering engine to deliver alternate style rules:

#content p {
	font-size: .8em;
	/* Hide from Mac IE5 \*/
	font-size: .9em;
	/* End hiding from Mac IE5 */
}

We’ve even used these exploits to serve up whole stylesheets altogether:

@import url(""core.css"");
@media tty {
	i{content:""\"";/*"" ""*/}} @import 'windows-ie5.css'; /*"";}
}/* */

The list goes on, and on, and on. For every browser, for every bug, there’s a patch available to fix some rendering bug.

But after some time working with standards-based layouts, I’ve found that CSS patches, as we’ve traditionally used them, become increasingly difficult to maintain. As stylesheets are modified over the course of a site’s lifetime, inline fixes we’ve written may become obsolete, making them difficult to find, update, or prune out of our CSS. A good patch requires a constant gardener to ensure that it adds more than just bloat to a stylesheet, and inline patches can be very hard to weed out of a decently sized CSS file.

Giving the Kids Separate Rooms

Since I joined Airbag Industries earlier this year, every project we’ve worked on has this in the head of its templates:

<link rel=""stylesheet"" href=""-/css/screen/main.css"" type=""text/css"" media=""screen, projection"" />
<!--[if lt IE 7]>
<link rel=""stylesheet"" href=""-/css/screen/patches/win-ie-old.css"" type=""text/css"" media=""screen, projection"" />
<![endif]-->
<!--[if gte IE 7]>
<link rel=""stylesheet"" href=""-/css/screen/patches/win-ie7-up.css"" type=""text/css"" media=""screen, projection"" />
<![endif]-->

The first element is, simply enough, a link element that points to the project’s main CSS file. No patches, no hacks: just pure, modern browser-friendly style rules. Which, nine times out of ten, will net you a design that looks like spilled eggnog in various versions of Internet Explorer.

But don’t reach for the mulled wine quite yet. Immediately after, we’ve got a brace of conditional comments wrapped around two other link elements. These odd-looking comments allow us to selectively serve up additional stylesheets just to the version of IE that needs them. We’ve got one for IE 6 and below:

<!--[if lt IE 7]>
<link rel=""stylesheet"" href=""-/css/screen/patches/win-ie-old.css"" type=""text/css"" media=""screen, projection"" />
<![endif]-->

And another for IE7 and above:

<!--[if gte IE 7]>
<link rel=""stylesheet"" href=""-/css/screen/patches/win-ie7-up.css"" type=""text/css"" media=""screen, projection"" />
<![endif]-->

Microsoft’s conditional comments aren’t exactly new, but they can be a valuable alternative to cooking CSS patches directly into a master stylesheet. And though they’re not a W3C-approved markup structure, I think they’re just brilliant because they innovate within the spec: non-IE devices will assume that the comments are just that, and ignore the markup altogether.

This does, of course, mean that there’s a little extra markup in the head of our documents. But this approach can seriously cut down on the unnecessary patches served up to the browsers that don’t need them. Namely, we no longer have to write rules like this in our main stylesheet:

#content {
	height: 1%;	// Let's force hasLayout for old versions of IE.
	line-height: 1.6;
	padding: 1em;
}
html>body #content {
	height: auto;	// Modern browsers get a proper height value.
}

Rather, we can simply write an un-patched rule in our core stylesheet:

#content {
	line-height: 1.6;
	padding: 1em;
}

And now, our patch for older versions of IE goes in—you guessed it—the stylesheet for older versions of IE:

#content {
	height: 1%;
}

The hasLayout patch is applied, our design’s repaired, and—most importantly—the patch is only seen by the browser that needs it. The “good” browsers don’t have to incur any added stylesheet weight from our IE patches, and Internet Explorer gets the conditional love it deserves.

Most importantly, this “compartmentalized” approach to CSS patching makes it much easier for me to patch and maintain the fixes applied to a particular browser. If I need to track down a bug for IE7, I don’t need to scroll through dozens or hundreds of rules in my core stylesheet: instead, I just open the considerably slimmer IE7-specific patch file, make my edits, and move right along.

Even Good Children Misbehave

While IE may occupy the bulk of our debugging time, there’s no denying that other popular, modern browsers will occasionally disagree on how certain bits of CSS should be rendered. But without something as, well, pimp as conditional comments at our disposal, how do we bring the so-called “good browsers” back in line with our design?

Assuming you’re loving the “one patch file per browser” model as much as I do, there’s just one alternative: JavaScript.

function isSaf() {
	var isSaf = (document.childNodes && !document.all && !navigator.taintEnabled && !navigator.accentColorName) ? true : false;
	return isSaf;
}
function isOp() {
	var isOp = (window.opera) ? true : false;
	return isOp;
}

Instead of relying on dotcom-era tactics of parsing the browser’s user-agent string, we’re testing here for support for various DOM objects, whose presence or absence we can use to reasonably infer the browser we’re looking at. So running the isOp() function, for example, will test for Opera’s proprietary window.opera object, and thereby accurately tell you if your user’s running Norway’s finest browser.

With scripts such as isOp() and isSaf() in place, you can then reasonably test which browser’s viewing your content, and insert additional link elements as needed.

function loadPatches(dir) {
	if (document.getElementsByTagName() && document.createElement()) {
		var head = document.getElementsByTagName(""head"")[0];
		if (head) {
			var css = new Array();
			if (isSaf()) {
				css.push(""saf.css"");
			} else if (isOp()) {
				css.push(""opera.css"");
			}
			if (css.length) {
				var link = document.createElement(""link"");
				link.setAttribute(""rel"", ""stylesheet"");
				link.setAttribute(""type"", ""text/css"");
				link.setAttribute(""media"", ""screen, projection"");
				for (var i = 0; i < css.length; i++) {
					var tag = link.cloneNode(true);
					tag.setAttribute(""href"", dir + css[0]);
					head.appendChild(tag);
				}
			}
		}
	}
}

Here, we’re testing the results of isSaf() and isOp(), one after the other. For each function that returns true, then the name of a new stylesheet is added to the oh-so-cleverly named css array. Then, for each entry in css, we create a new link element, point it at our patch file, and insert it into the head of our template.

Fire it up using your favorite onload or DOMContentLoaded function, and you’re good to go.

Scripteat Emptor

At this point, some of the audience’s more conscientious ‘scripters may be preparing to lob figgy pudding at this author’s head. And that’s perfectly understandable; relying on JavaScript to patch CSS chafes a bit against the normally clean separation we have between our pages’ content, presentation, and behavior layers.

And beyond the philosophical concerns, this approach comes with a few technical caveats attached:

Browser detection? So un-133t.

Browser detection is not something I’d typically recommend. Whenever possible, a proper DOM script should check for the support of a given object or method, rather than the device with which your users view your content.

It’s JavaScript, so don’t count on it being available.

According to one site, roughly four percent of Internet users don’t have JavaScript enabled. Your site’s stats might be higher or lower than this number, but still: don’t expect that every member of your audience will see these additional stylesheets, and ensure that your content’s still accessible with JS turned off.

Be a constant gardener.

The sample isSaf() and isOp() functions I’ve written will tell you if the user’s browser is Safari or Opera. As a result, stylesheets written to patch issues in an old browser may break when later releases repair the relevant CSS bugs.

You can, of course, add logic to these simple little scripts to serve up version-specific stylesheets, but that way madness may lie. In any event, test your work vigorously, and keep testing it when new versions of the targeted browsers come out. Make sure that a patch written today doesn’t become a bug tomorrow.

Patching Firefox, Opera, and Safari isn’t something I’ve had to do frequently: still, there have been occasions where the above script’s come in handy. Between conditional comments, careful CSS auditing, and some judicious JavaScript, browser-based bugs can be handled with near-surgical precision.

So pass the ‘nog. It’s patchin’ time.",2007,Ethan Marcotte,ethanmarcotte,2007-12-15T00:00:00+00:00,https://24ways.org/2007/conditional-love/,code
147,Christmas Is In The AIR,"That’s right, Christmas is coming up fast and there’s plenty of things to do. Get the tree and lights up, get the turkey, buy presents and who know what else. And what about Santa? He’s got a list. I’m pretty sure he’s checking it twice.

Sure, we could use an existing list making web site or even a desktop widget. But we’re geeks! What’s the fun in that? Let’s build our own to-do list application and do it with Adobe AIR!

What’s Adobe AIR?

Adobe AIR, formerly codenamed Apollo, is a runtime environment that runs on both Windows and OSX (with Linux support to follow). This runtime environment lets you build desktop applications using Adobe technologies like Flash and Flex. Oh, and HTML. That’s right, you web standards lovin’ maniac. You can build desktop applications that can run cross-platform using the trio of technologies, HTML, CSS and JavaScript.

If you’ve tried developing with AIR before, you’ll need to get re-familiarized with the latest beta release as many things have changed since the last one (such as the API and restrictions within the sandbox.)

To get started

To get started in building an AIR application, you’ll need two basic things:


	The AIR runtime. The runtime is needed to run any AIR-based application.
	The SDK. The software development kit gives you all the pieces to test your application. Unzip the SDK into any folder you wish.


You’ll also want to get your hands on the JavaScript API documentation which you’ll no doubt find yourself getting into before too long. (You can download it, too.)

Also of interest, some development environments have support for AIR built right in. Aptana doesn’t have support for beta 3 yet but I suspect it’ll be available shortly.

Within the SDK, there are two main tools that we’ll use: one to test the application (ADL) and another to build a distributable package of our application (ADT). I’ll get into this some more when we get to that stage of development.

Building our To-do list application

The first step to building an application within AIR is to create an XML file that defines our default application settings. I call mine application.xml, mostly because Aptana does that by default when creating a new AIR project. It makes sense though and I’ve stuck with it. Included in the templates folder of the SDK is an example XML file that you can use.

The first key part to this after specifying things like the application ID, version, and filename, is to specify what the default content should be within the content tags. Enter in the name of the HTML file you wish to load. Within this HTML file will be our application.

<content>ui.html</content>

Create a new HTML document and name it ui.html and place it in the same directory as the application.xml file. The first thing you’ll want to do is copy over the AIRAliases.js file from the frameworks folder of the SDK and add a link to it within your HTML document.

<script type=""text/javascript"" src=""AIRAliases.js""></script>

The aliases create shorthand links to all of the Flash-based APIs.

Now is probably a good time to explain how to debug your application.

Debugging our application

So, with our XML file created and HTML file started, let’s try testing our ‘application’. We’ll need the ADL application located in BIN folder of the SDK and tell it to run the application.xml file.

/path/to/adl /path/to/application.xml

You can also just drag the XML file onto ADL and it’ll accomplish the same thing. If you just did that and noticed that your blank application didn’t load, you’d be correct. It’s running but isn’t visible. Which at this point means you’ll have to shut down the ADL process. Sorry about that!

Changing the visibility

You have two ways to make your application visible. You can do it automatically by setting the placing true in the visible tag within the application.xml file.

<visible>true</visible>

The other way is to do it programmatically from within your application. You’d want to do it this way if you had other startup tasks to perform before showing the interface. To turn the UI on programmatically, simple set the visible property of nativeWindow to true.

<script type=""text/javascript"">
	nativeWindow.visible = true;
</script>

Sandbox Security

Now that we have an application that we can see when we start it, it’s time to build the to-do list application. In doing so, you’d probably think that using a JavaScript library is a really good idea — and it can be but there are some limitations within AIR that have to be considered.

An HTML document, by default, runs within the application sandbox. You have full access to the AIR APIs but once the onload event of the window has fired, you’ll have a limited ability to make use of eval and other dynamic script injection approaches. This limits the ability of external sources from gaining access to everything the AIR API offers, such as database and local file system access. You’ll still be able to make use of eval for evaluating JSON responses, which is probably the most important if you wish to consume JSON-based services.

If you wish to create a greater wall of security between AIR and your HTML document loading in external resources, you can create a child sandbox. We won’t need to worry about it for our application so I won’t go any further into it but definitely keep this in mind.

Finally, our application

Getting tired of all this preamble? Let’s actually build our to-do list application. I’ll use jQuery because it’s small and should suit our needs nicely. Let’s begin with some structure:

<body>
	<input type=""text"" id=""text"" value="""">
	<input type=""button"" id=""add"" value=""Add"">
	<ul id=""list""></ul>
</body>

Now we need to wire up that button to actually add a new item to our to-do list.

<script type=""text/javascript"">
$(document).ready(function(){
	// make sure the application is visible
	nativeWindow.visible = true;
	$('#add').click(function(){
		var t = $('#text').val();
		if(t)
		{
			// use DOM methods to create the new list item
			var li = document.createElement('li');
			// the extra space at the end creates a buffer between the text
			// and the delete link we're about to add
			li.appendChild(document.createTextNode(t + ' '));
			// create the delete link
			var del = document.createElement('a');
			// this makes it a true link. I feel dirty doing this.
			del.setAttribute('href', '#');
			del.addEventListener('click', function(evt){
				this.parentNode.parentNode.removeChild(this.parentNode);
			});
			del.appendChild(document.createTextNode('[del]'));
			li.appendChild(del);
			// append everything to the list
			$('#list').append(li);
			//reset the text box
			$('#text').val('');
		}
	})
});
</script>

And just like that, we’ve got a to-do list! That’s it! Just never close your application and you’ll remember everything. Okay, that’s not very practical. You need to have some way of storing your to-do items until the next time you open up the application.

Storing Data

You’ve essentially got 4 different ways that you can store data:


	Using the local database. AIR comes with SQLLite built in. That means you can create tables and insert, update and select data from that database just like on a web server.
	Using the file system. You can also create files on the local machine. You have access to a few folders on the local system such as the documents folder and the desktop.
	Using EcryptedLocalStore. I like using the EcryptedLocalStore because it allows you to easily save key/value pairs and have that information encrypted. All this within just a couple lines of code.
	Sending the data to a remote API. Our to-do list could sync up with Remember the Milk, for example.


To demonstrate some persistence, we’ll use the file system to store our files. In addition, we’ll let the user specify where the file should be saved. This way, we can create multiple to-do lists, keeping them separate and organized.

The application is now broken down into 4 basic tasks:


	Load data from the file system.
	Perform any interface bindings.
	Manage creating and deleting items from the list.
	Save any changes to the list back to the file system.


Loading in data from the file system

When the application starts up, we’ll prompt the user to select a file or specify a new to-do list. Within AIR, there are 3 main file objects: File, FileMode, and FileStream. File handles file and path names, FileMode is used as a parameter for the FileStream to specify whether the file should be read-only or for write access. The FileStream object handles all the read/write activity.

The File object has a number of shortcuts to default paths like the documents folder, the desktop, or even the application store. In this case, we’ll specify the documents folder as the default location and then use the browseForSave method to prompt the user to specify a new or existing file. If the user specifies an existing file, they’ll be asked whether they want to overwrite it.

var store = air.File.documentsDirectory;
var fileStream = new air.FileStream();
store.browseForSave(""Choose To-do List"");

Then we add an event listener for when the user has selected a file. When the file is selected, we check to see if the file exists and if it does, read in the contents, splitting the file on new lines and creating our list items within the interface.

store.addEventListener(air.Event.SELECT, fileSelected);
function fileSelected()
{
	air.trace(store.nativePath);
	// load in any stored data
	var byteData = new air.ByteArray();
	if(store.exists)
	{
		fileStream.open(store, air.FileMode.READ);
		fileStream.readBytes(byteData, 0, store.size);
		fileStream.close();

		if(byteData.length > 0)
		{
			var s = byteData.readUTFBytes(byteData.length);
			oldlist = s.split(“\r\n”);

			// create todolist items
			for(var i=0; i < oldlist.length; i++)
			{
				createItem(oldlist[i], (new Date()).getTime() + i );
			}
		}
	}
}

Perform Interface Bindings

This is similar to before where we set the click event on the Add button but we’ve moved the code to save the list into a separate function.

$('#add').click(function(){
		var t = $('#text').val();
		if(t){
			// create an ID using the time
			createItem(t, (new Date()).getTime() );
		}
})

Manage creating and deleting items from the list

The list management is now in its own function, similar to before but with some extra information to identify list items and with calls to save our list after each change.

function createItem(t, id)
{
	if(t.length == 0) return;
	// add it to the todo list
	todolist[id] = t;
	// use DOM methods to create the new list item
	var li = document.createElement('li');
	// the extra space at the end creates a buffer between the text
	// and the delete link we're about to add
	li.appendChild(document.createTextNode(t + ' '));
	// create the delete link
	var del = document.createElement('a');
	// this makes it a true link. I feel dirty doing this.
	del.setAttribute('href', '#');
	del.addEventListener('click', function(evt){
		var id = this.id.substr(1);
		delete todolist[id]; // remove the item from the list
		this.parentNode.parentNode.removeChild(this.parentNode);
		saveList();
	});
	del.appendChild(document.createTextNode('[del]'));
	del.id = 'd' + id;
	li.appendChild(del);
	// append everything to the list
	$('#list').append(li);
	//reset the text box
	$('#text').val('');
	saveList();
}

Save changes to the file system

Any time a change is made to the list, we update the file. The file will always reflect the current state of the list and we’ll never have to click a save button. It just iterates through the list, adding a new line to each one.

function saveList(){
	if(store.isDirectory) return;
	var packet = '';
	for(var i in todolist)
	{
		packet += todolist[i] + '\r\n';
	}
	var bytes = new air.ByteArray();
	bytes.writeUTFBytes(packet);
	fileStream.open(store, air.FileMode.WRITE);
	fileStream.writeBytes(bytes, 0, bytes.length);
	fileStream.close();
}

One important thing to mention here is that we check if the store is a directory first. The reason we do this goes back to our browseForSave call. If the user cancels the dialog without selecting a file first, then the store points to the documentsDirectory that we set it to initially. Since we haven’t specified a file, there’s no place to save the list.

Hopefully by this point, you’ve been thinking of some cool ways to pimp out your list. Now we need to package this up so that we can let other people use it, too.

Creating a Package

Now that we’ve created our application, we need to package it up so that we can distribute it. This is a two step process. The first step is to create a code signing certificate (or you can pay for one from Thawte which will help authenticate you as an AIR application developer).

To create a self-signed certificate, run the following command. This will create a PFX file that you’ll use to sign your application.

adt -certificate -cn todo24ways 1024-RSA todo24ways.pfx mypassword

After you’ve done that, you’ll need to create the package with the certificate

adt -package -storetype pkcs12 -keystore todo24ways.pfx todo24ways.air application.xml .

The important part to mention here is the period at the end of the command. We’re telling it to package up all files in the current directory.

After that, just run the AIR file, which will install your application and run it.

Important things to remember about AIR

When developing an HTML application, the rendering engine is Webkit. You’ll thank your lucky stars that you aren’t struggling with cross-browser issues. (My personal favourites are multiple backgrounds and border radius!)

Be mindful of memory leaks. Things like Ajax calls and event binding can cause applications to slowly leak memory over time. Web pages are normally short lived but desktop applications are often open for hours, if not days, and you may find your little desktop application taking up more memory than anything else on your machine!

The WebKit runtime itself can also be a memory hog, usually taking about 15MB just for itself. If you create multiple HTML windows, it’ll add another 15MB to your memory footprint. Our little to-do list application shouldn’t be much of a concern, though.

The other important thing to remember is that you’re still essentially running within a Flash environment. While you probably won’t notice this working in small applications, the moment you need to move to multiple windows or need to accomplish stuff beyond what HTML and JavaScript can give you, the need to understand some of the Flash-based elements will become more important.

Lastly, the other thing to remember is that HTML links will load within the AIR application. If you want a link to open in the users web browser, you’ll need to capture that event and handle it on your own. The following code takes the HREF from a clicked link and opens it in the default web browser.

air.navigateToURL(new air.URLRequest(this.href));

Only the beginning

Of course, this is only the beginning of what you can do with Adobe AIR. You don’t have the same level of control as building a native desktop application, such as being able to launch other applications, but you do have more control than what you could have within a web application. Check out the Adobe AIR Developer Center for HTML and Ajax for tutorials and other resources.

Now, go forth and create your desktop applications and hopefully you finish all your shopping before Christmas!

157,Capturing Caps Lock,"One of the more annoying aspects of having to remember passwords (along with having to remember loads of them) is that if you’ve got Caps Lock turned on accidentally when you type one in, it won’t work, and you won’t know why. Most desktop computers alert you in some way if you’re trying to enter your password to log on and you’ve enabled Caps Lock; there’s no reason why the web can’t do the same. What we want is a warning – maybe the user wants Caps Lock on, because maybe their password is in capitals – rather than something that interrupts what they’re doing. Something subtle.

But that doesn’t answer the question of how to do it. Sadly, there’s no way of actually detecting whether Caps Lock is on directly. However, there’s a simple work-around; if the user presses a key, and it’s a capital letter, and they don’t have the Shift key depressed, why then they must have Caps Lock on! Simple. 

DOM scripting allows your code to be notified when a key is pressed in an element; when the key is pressed, you get the ASCII code for that key. Capital letters, A to Z, have ASCII codes 65 to 90. So, the code would look something like:

on a key press
	if the ASCII code for the key is between 65 and 90 *and* if shift is pressed
		warn the user that they have Caps Lock on, but let them carry on
	end if
end keypress

The actual JavaScript for this is more complicated, because both event handling and keypress information differ across browsers. Your event handling functions are passed an event object, except in Internet Explorer where you use the global event object; the event object has a which parameter containing the ASCII code for the key pressed, except in Internet Explorer where the event object has a keyCode parameter; some browsers store whether the shift key is pressed in a shiftKey parameter and some in a modifiers parameter. All this boils down to code that looks something like this:

keypress: function(e) {
	var ev = e ? e : window.event;
	if (!ev) {
		return;
	}
	var targ = ev.target ? ev.target : ev.srcElement;
	// get key pressed
	var which = -1;
	if (ev.which) {
		which = ev.which;
	} else if (ev.keyCode) {
		which = ev.keyCode;
	}
	// get shift status
	var shift_status = false;
	if (ev.shiftKey) {
		shift_status = ev.shiftKey;
	} else if (ev.modifiers) {
		shift_status = !!(ev.modifiers & 4);
	}

	// At this point, you have the ASCII code in “which”, 
	// and shift_status is true if the shift key is pressed
}

Then it’s just a check to see if the ASCII code is between 65 and 90 and the shift key is pressed. (You also need to do the same work if the ASCII code is between 97 (a) and 122 (z) and the shift key is not pressed, because shifted letters are lower-case if Caps Lock is on.)

if (((which >= 65 && which <= 90) && !shift_status) || 
	((which >= 97 && which <= 122) && shift_status)) {
	// uppercase, no shift key
	/* SHOW THE WARNING HERE */
} else {
	/* HIDE THE WARNING HERE */
}

The warning can be implemented in many different ways: highlight the password field that the user is typing into, show a tooltip, display text next to the field. For simplicity, this code shows the warning as a previously created image, with appropriate alt text. Showing the warning means creating a new <img> tag with DOM scripting, dropping it into the page, and positioning it so that it’s next to the appropriate field. The image looks like this:



You know the position of the field the user is typing into (from its offsetTop and offsetLeft properties) and how wide it is (from its offsetWidth properties), so use createElement to make the new img element, and then absolutely position it with style properties so that it appears in the appropriate place (near to the text field). 

The image is a transparent PNG with an alpha channel, so that the drop shadow appears nicely over whatever else is on the page. Because Internet Explorer version 6 and below doesn’t handle transparent PNGs correctly, you need to use the AlphaImageLoader technique to make the image appear correctly.

newimage = document.createElement('img');
newimage.src = ""http://farm3.static.flickr.com/2145/2067574980_3ddd405905_o_d.png"";
newimage.style.position = ""absolute"";
newimage.style.top = (targ.offsetTop - 73) + ""px"";
newimage.style.left = (targ.offsetLeft + targ.offsetWidth - 5) + ""px"";
newimage.style.zIndex = ""999"";
newimage.setAttribute(""alt"", ""Warning: Caps Lock is on"");
if (newimage.runtimeStyle) {
	// PNG transparency for IE
	newimage.runtimeStyle.filter += ""progid:DXImageTransform.Microsoft.AlphaImageLoader(src='http://farm3.static.flickr.com/2145/2067574980_3ddd405905_o_d.png',sizingMethod='scale')"";
}
document.body.appendChild(newimage);

Note that the alt text on the image is also correctly set. Next, all these parts need to be pulled together. On page load, identify all the password fields on the page, and attach a keypress handler to each. (This only needs to be done for password fields because the user can see if Caps Lock is on in ordinary text fields.)

var inps = document.getElementsByTagName(""input"");
for (var i=0, l=inps.length; i

The “create an image” code from above should only be run if the image is not already showing, so instead of creating a newimage object, create the image and attach it to the password field so that it can be checked for later (and not shown if it’s already showing). For safety, all the code should be wrapped up in its own object, so that its functions don’t collide with anyone else’s functions. So, create a single object called capslock and make all the functions be named methods of the object:

var capslock = {
	... 
	keypress: function(e) {
	}
	...
}

Also, the “create an image” code is saved into its own named function, show_warning(), and the converse “remove the image” code into hide_warning(). This has the advantage that developers can include the JavaScript library that has been written here, but override what actually happens with their own code, using something like:

<script src=""jscapslock.js"" type=""text/javascript""></script>
<script type=""text/javascript"">
	capslock.show_warning(target) {
		// do something different here to warn the user
	}
	capslock.hide_warning(target) {
		// hide the warning that we created in show_warning() above
	}
</script>

And that’s all. Simply include the JavaScript library in your pages, override what happens on a warning if that’s more appropriate for what you’re doing, and that’s all you need.

167,Back To The Future of Print,"By now we have weathered the storm that was the early days of web development, a dangerous time when we used tables, inline CSS and separate pages for print only versions. We can reflect in a haggard old sea-dog manner (“yarrr… I remember back in the browser wars…”) on the bad practices of the time. We no longer need convincing that print stylesheets are the way to go1, though some of the documentation for them is a little outdated now.

I am going to briefly cover 8 tips and 4 main gotchas when creating print stylesheets in our more enlightened era.

Getting started

As with regular stylesheets, print CSS can be included in a number of ways2, for our purposes we are going to be using the link
element.

<link rel=""stylesheet"" type=""text/css"" media=""print"" href=""print.css"">

This is still my favourite way of linking to CSS files, its easy to see what files are being included and to what media they are being applied to. Without the media attribute specified the link element defaults to the media type ‘all’ which means that the styles within then apply to print and screen alike. The media type ‘screen’ only applies to the screen and wont be picked up by print, this is the best way of hiding styles from print.

Make sure you include your print styles after all your other CSS, because you will need to override certain rules and this is a lot easier if you are flowing with the cascade than against it!

Another thing you should be thinking is ‘does it need to be printed’. Consider the context3, if it is not a page that is likely to be printed, such as a landing page or a section index then the print styles should resemble the way the page looks on the screen.

Context is really important for the design of your print stylesheet, all the tips and tricks that follow should be taken in the context of the page. If for example you are designing a print stylesheet for an item in a shopping cart, it is irrelevant for the user to know the exact url of the link that takes them to your checkout.

Tips and tricks

During these tip’s we are going to build up print styles for a textileRef:11112857385470b854b8411:linkStartMarker:“simple
example”:/examples/back-to-the-future-of-print/demo-1.html

1. Remove the cruft

First things first, navigation, headers and most page furniture are pretty much useless and dead space in print so they will need to be removed, using display:none;.

2. Linearise your content

Content doesn’t work so well in columns in print, especially if the content columns are long and intend to stretch over multiple columns (as mentioned in the gotcha section below). You might want to consider Lineariseing the content to flow down the page. If you have your source order in correct priority this will make things a lot easier4.

3. Improve your type

Once you have removed all the useless cruft and jiggled things about a bit, you can concentrate more on the typography of the page.

Typography is a complex topic5, but simply put serif-ed fonts such as Georgia work better on print and sans serif-ed fonts such as Verdana are more appropriate for screen use. You will probably want to increase font size and line height and change from px to pt (which is specifically a print measurement).

4. Go wild on links

There are some incredibly fun things you can do with links in print using CSS. There are two schools of thought, one that consider it is best to disguise inline links as body text because they are not click-able on paper. Personally I believe it is useful to know for reference that the document did link to somewhere originally.

When deciding which approach to take, consider the context of your document, do people need to know where they would have gone to? will it help or hinder them to know this information? Also for an alternative to the below, take a look at Aaron Gustafson’s article on generating footnotes for print6.

Using some clever selector trickery and CSS generated content you can have the location of the link generated after the link itself.

HTML:

<p>I wish <a href=""http://www.google.com/"">Google</a> could find <a href=""/photoOfMyKeys.jpg"">my keys</a></p>

CSS:

a:link:after,
a:visited:after,
a:hover:after,
a:active:after {
	content: "" <"" attr(href) ""> "";
}

But this is not perfect, in the above example the content of the href is just naively plonked after the link text:

I wish Google <http://www.google.com/> would find my keys </photoOfMyKeys.jpg>

As looking back over this printout the user is not immediately aware of the location of the link, a better solution is to use even more crazy selectors to deal with relative links. We can also add a style to the generated content so it is distinguishable from the link text itself.

CSS:

a:link:after,
a:visited:after,
a:hover:after,
a:active:after {
	content: "" <"" attr(href) ""> "";
	color: grey;
	font-style: italic;
	font-weight: normal;
}
a[href^=""/""]:after {
	content: "" <http://www.example.com""attr(href)""> "";
}

The output is now what we were looking for (you will need to replace example.com with your own root URL):

I wish Google <http://www.google.com/> would find my keys <http://www.example.com/photoOfMyKeys.jpg>

Using regular expressions on the attribute selectors, one final thing you can do is to suppress the generated content on mailto: links, if for example you know the link text always reflects the email address. Eg:

HTML:

<a href=""mailto:me@example.com"">me@example.com</a>

CSS:

a[href^=""mailto""]:after {
	content: """";
}

This example shows the above in action.

Of course with this clever technique, there are the usual browser support issues. While it won’t look as intended in browsers such as Internet Explorer 6 and 7 (IE6 and IE7) it will not break either and will just degrade gracefully because IE cannot do generated content. To the best of my knowledge Safari 2+ and Opera 9.X support a colour set on generated content whereas Firefox 2 & Camino display this in black regardless of the link or inherited text colour.

5. Jazz your headers for print

This is more of a design consideration, don’t go too nuts though; there are a lot more limitations in print media than on screen. For this example we are going to go for is having a bottom border on h2’s and styling other headings with graduating colors or font sizes.

And here is the example complete with jazzy headers.

6. Build in general hooks

If you are building a large site with many different types of page, you may find it useful to build into your CSS structure, classes that control what is printed (e.g. noprint and printonly). This may not be semantically ideal, but in the past I have found it really useful for maintainability of code across large and varied sites

7. For that extra touch of class

When printing pages from a long URL, even if the option is turned on to show the location of the page in the header, browsers may still display a truncated (and thus useless) version.

Using the above tip (or just simply setting to display:none in screen and display:block in print) you can insert the URL of the page you are currently on for print only, using JavaScript’s window.location.href variable.

function addPrintFooter() {
	var p = document.createElement('p');
	p.className = 'print-footer';
	p.innerHTML = window.location.href;
	document.body.appendChild(p);
}

You can then call this function using whichever onload or ondomready handler suits your fancy. Here is our familiar demo to show all the above in action

8. Tabular data across pages

If you are using tabled data in your document there are a number of things you can do to increase usability of long tables over several pages. If you use the <thead> element this should repeat your table headers on the next page should your table be split. You will need to set thead {display: table-header-group;} explicitly for IE even though this should be the default value.

Also if you use tr {page-break-inside: avoid;} this should (browser support depending) stop your table row from breaking across two pages. For more information on styling tables for print please see the CSS discuss wiki7.

Gotchas

1. Where did all my content go?

Absolutely the most common mistake I see with print styles is the truncated content bug. The symptom of this is that only the first page of a div’s content will be printed, the rest will look truncated after this.

Floating long columns may still have this affect, as mentioned in Eric Meyer’s article on ‘A List Apart’ article from 20028; though in testing I am no longer able to replicate this. Using overflow:hidden on long content in Firefox however still causes this truncation. Overflow hidden is commonly used to clear floats9.

A simple fix can be applied to resolve this, if the column is floated you can override this with float:none similarly overflow:hidden can be overridden with overflow:visible or the offending rules can be banished to a screen only stylesheet.

Using position:absolute on long columns also has a very similar effect in truncating the content, but can be overridden in print with position:static;

Whilst I only recommend having a print stylesheet for content pages on your site; do at least check other landing pages, section indexes and your homepage. If these are inaccessible in print possibly due to the above gotcha, it might be wise to provide a light dusting of print styles or move the offending overflow / float rules to a screen only stylesheet to fix the issues.

2. Damn those background browser settings

One of the factors of life you now need to accept is that you can’t control the user’s browser settings, no more than you can control whether or not they use IE6. Most browsers by default will not print background colours or images unless explicitly told to by the user.

Naturally this causes a number of problems, for starters you will need to rethink things like branding. At this point it helps if you are doing the print styles early in the project so that you can control the logo not being a background image for example.

Where colour is important to the meaning of the document, for example a status on an invoice, bear in mind that a textural representation will also need to be supplied as the user may be printing in black and white. Borders will print however regardless of setting, so assuming the user is printing in colour you can always use borders to indicate colour.

Check the colour contrast of the text against white, this may need to be altered without backgrounds. You should check how your page looks with backgrounds turned on too, for consistency with the default browser settings you may want to override your background anyway.

One final issue with backgrounds being off is list items. It is relatively common practice to suppress the list-style-type and replace with a background image to finely control the bullet positioning. This technique doesn’t translate to print, you will need to disable this background bullet and re-instate your trusty friend the list-style-type.

3. Using JavaScript in your CSS? … beware IE6

Internet explorer has an issue that when Javascript is used in a stylesheet it applies this to all media types even if only applied to screen. For example, if you happen to be using expressions to set a width for IE, perhaps to mimic min-width, a simple width:100% !important rule can overcome the effects the expression has on your print styles10.

4. De-enhance your Progressive enhancements

Quite a classic “doh” moment is when you realise that, of course paper doesn’t support Javascript. If you have any dynamic elements on the page, for example a document collapsed per section, you really should have been using Progressive enhancement techniques11 and building for browsers without Javascript first, adding in the fancy stuff later.

If this is the case it should be trivial to override your wizzy JS styles in your print stylesheet, to display all your content and make it accessible for print, which is by far the best method of achieving this affect.

And Finally…

I refer you back to the nature of the document in hand, consider the context of your site and the page. Use the tips here to help you add that extra bit of flair to your printed media.

Be careful you don’t get caught out by the common gotchas, keep the design simple, test cross browser and relish in the medium of print.

150,"A Gift Idea For Your Users: Respect, Yo","If, indeed, it is the thought that counts, maybe we should pledge to make more thoughtful design decisions.  In addition to wowing people who use the Web sites we build with novel features, nuanced aesthetics and the new new thing, maybe we should also thread some subtle things throughout our work that let folks know:  hey, I’m feeling ya.  We’re simpatico.  I hear you loud and clear.

It’s not just holiday spirit that moves me to talk this way.  As good as people are, we need more than the horizon of karma to overcome that invisible demon, inertia.  Makers of the Web, respectful design practices aren’t just the right thing, they are good for business.  Even if your site is the one and only place to get experience x, y or zed, you don’t rub someone’s face in it.  You keep it free flowing, you honor the possible back and forth of a healthy transaction, you are Johnny Appleseed with the humane design cues.  You make it clear that you are in it for the long haul.

A peek back:



Think back to what search (and  strategy) was like before Google launched a super clean page with “I’m Feeling Lucky” button.  Aggregation was the order of the day (just go back and review all the ‘strategic alliances’ that were announced daily.)  Yet the GOOG comes along with this zen layout (nope, we’re not going to try to make you look at one of our media properties) and a bold, brash, teleport-me-straight-to-the-first-search-result button.  It could have been titled “We’re Feeling Cocky”.  These were radical design decisions that reset how people thought about search services.  Oh, you mean I can just find what I want and get on with it?

It’s maybe even more impressive today, after the GOOG has figured out how to monetize attention better than anyone.  “I’m Feeling Lucky” is still there.  No doubt, it costs the company millions.  But by leaving a little money on the table, they keep the basic bargain they started to strike in 1997.  We’re going to get you where you want to go as quickly as possible.

Where are the places we might make the same kind of impact in our work?  Here are a few ideas:

Respect People’s Time

As more services become more integrated with our lives, this will only become more important.  How can you make it clear that you respect the time a user has granted you?

User-Oriented Defaults

Default design may be the psionic tool in your belt.  Unseen, yet pow-er-ful.  Look at your defaults.  Who are they set up to benefit?  Are you depending on users not checking off boxes so you can feel ok about sending them email they really don’t want?  Are you depending on users not checking off boxes so you tilt privacy values in ways most beneficial for your SERPs?  Are you making it a little too easy for 3rd party applications to run buckwild through your system?

There’s being right and then there’s being awesome.  Design to the spirit of the agreement and not the letter.

See this?



Make sure that’s really the experience you think people want.  Whenever I see a service that defaults to not opting me in their newsletter just because I bought a t shirt from them, you can be sure that I trust them that much more.  And they are likely to see me again.

Reduce, Reuse

It’s likely that people using your service will have data and profile credentials elsewhere.  You should really think hard about how you can let them repurpose some of that work within your system.  Can you let them reduce the number of logins/passwords they have to manage by supporting OpenID?  Can you let them reuse profile information from another service by slurping in (or even subscribing) to hCards?  Can you give them a leg up by reusing a friends list they make available to you?  (Note:  please avoid the anti-pattern of inviting your user to upload all her credential data from 3rd party sites into your system.)

This is a much larger issue, and if you’d like to get involved, have a look at the wiki, and dive in.

Make it simple to leave

Oh, this drives me bonkers.  Again, the more simple you make it to increase or decrease involvement in your site, or to just opt-out altogether, the better.  This example from Basecamp is instructive:



At a glance, I can see what the implications are of choosing a different type of account.  I can also move between account levels with one click.  Finally, I can cancel the service easily.  No hoop jumping.  Also, it should be simple for users to take data with them or delete it.

Let Them Have Fun

Don’t overlook opportunities for pleasure.  Even the most mundane tasks can be made more enjoyable.  Check out one of my favorite pieces of interaction design from this past year:



Holy knob fiddling, Batman!  What a great way to get people to play with preference settings:  an equalizer metaphor.  Those of a certain age will recall how fun it was to make patterns with your uncle’s stereo EQ.  I think this is a delightful way to encourage people to optimize their own experience of the news feed feature.  Given the killer nature of this feature, it was important for Facebook to make it easy to fine tune.

I’d also point you to Flickr’s Talk Like A Pirate Day Easter egg as another example of design that delights.  What a huge amount of work for a one-off, totally optional way to experience the site.  And what fun.  And how true to its brand persona.  Brill.

Anti-hype

Don’t talk so much.  Rather, ship and sample.  Release code, tell the right users.  See what happens.   Make changes.  Extend the circle a bit by showing some other folks.  Repeat.

The more you hype coming features, the more you talk about what isn’t yet, the more you build unrealistic expectations.  Your genius can’t possibly match our collective dreaming.  Disappointment is inevitable.  Yet, if you craft the right melody and make it simple for people to hum your tune, it will spread.  Give it time.  Listen.

Speak the Language of the Tribe

It’s respectful to speak in a human way.  Not that you have to get all zOMGWTFBBQ!!1 in your messaging.  People respond when you speak to them in a way that sounds natural.  Natural will, of course, vary according to context.  Again, listen in and people will signal the speech that works in that group for those tasks.  Reveal those cues in your interface work and you’ll have powerful proof that actual people are working on your Web site.

This example of Pownce‘s gender selector is the kind of thing I’m talking about:



Now, this doesn’t mean you should mimic the lingo on some cool kidz site.  Your service doesn’t need to have a massage when it’s down.  Think about what works for you and your tribe.  Excellent advice here from Feedburner’s Dick Costolo on finding a voice for your service.  Also, Mule Design’s Erika Hall has an excellent talk on improving your word fu.

Pass the mic, yo

Here is a crazy idea:  you could ask your users what they want.  Maybe you could even use this input to figure out what they really want.  Tools abound.  Comments, wikis, forums, surveys.  Embed the sexy new Get Satisfaction widget and have a dynamic FAQ running.

The point is that you make it clear to people that they have a means of shaping the service with you.  And you must showcase in some way that you are listening, evaluating and taking action against some of that user input.

You get my drift.  There are any number of ways we can show respect to those who gift us with their time, data, feedback, attention, evangelism, money.  Big things are in the offing.  I can feel the love already.",2007,Brian Oberkirch,brianoberkirch,2007-12-23T00:00:00+00:00,https://24ways.org/2007/a-gift-idea-for-your-users-respect-yo/,ux
158,10 Ways To Get Design Approval,"One of the most challenging parts of the web design process is getting design sign off. It can prove time consuming, demoralizing and if you are not careful can lead to a dissatisfied client. What is more you can end up with a design that you are ashamed to include in your portfolio.

How then can you ensure that the design you produce is the one that gets built? How can you get the client to sign off on your design? Below are 10 tips learnt from years of bitter experience.

1. Define the role of the client and designer

Many of the clients you work with will not have been involved in a web project before. Even if they have they may have worked in a very different way to what you would expect. Take the time at the beginning of the project to explain their role in the design of the site.

The best approach is to emphasis that their job is to focus on the needs of their users and business. They should concentrate on the broad issues, while you worry about the details of layout, typography and colour scheme.

By clarifying what you expect from the client, you help them to provide the right kind of input throughout the process.

2. Understand the business

Before you open up Photoshop or put pen to paper, take the time to make sure you properly understand not only the brief but the organization behind the site. By understanding their business objectives, organizational structure and marketing strategy your design decisions will be better informed.

You cannot rely upon the brief to provide all of the information you need. It is important to dig deeper and get as good an understanding of their business as possible. This information will prove invaluable when justifying your design decisions.

3. Understand the users

We all like to think of ourselves as user centric designers, but exactly how much effort do you put into knowing your users before beginning the design process?

Take the time to really understand them the best you can. Try to meet with some real prospective users and get to know their needs. Failing that work with the client to produce user personas to help picture exactly what kind of people they are. 

Understanding your users not only improves the quality of your work, but also helps move the discussion away from the personal preferences of the client, to the people who’s opinion really matters.

4. Avoid multiple concepts

Many clients like the idea of having the option to choose between multiple design concepts. However, although on the surface this might appear to be a good idea it can ultimately be counterproductive for design sign off.

In a world of limited budgets it is unwise to waste money on producing designs that are ultimately going to be thrown away. The resources would be better spent refining a single design through multiple iterations.

What is more, multiple concepts often cause confusion rather than clarity. It is common for a client to request one element from one design and another from the second. As any designer knows this seldom works.

5. Use mood boards

Clients are often better at expressing what they don’t like than what they do. This is one of the reasons why they favour producing multiple design concepts. An alternative less costly approach is to create a series of mood boards. These boards contain a collection of colours, typography and imagery which represent different “moods” or directions, which the design could take. 

Mood boards are quick and easy to produce allowing you to try out various design approaches with the client without investing the time needed to produce complete design concepts. This means that by the time you develop a concept the client and designer have already established an understanding about the direction of the design.

6. Say what you like

It is not uncommon for a client to ask for a design that looks similar to another site they like. The problem is that it can often be hard to establish exactly what it is about the site that attracts them. Also in many cases the sites they like are not something you are keen to emulate!

A better approach that was suggested to me by Andy Budd is to show them sites that you think the design should emulate. Keep a collection of screen captures from well designed sites and pick out a few that are relevant to that particular client. Explain why you feel these designs might suit their project and ask for their feedback. If they don’t like your choices then expose them to more of your collection and see what they pick out.

7. Wireframe the homepage

Often clients find it hard to distinguish between design and content and so sometimes reject a design on the basis that the content is not right. This is particularly true when signing off the homepage.

You may therefore find it useful to establish the homepage content before producing the design. That way once they see the design they will not be distracted by the content. One of the best ways to do this is by producing a basic wireframe consisting of a series of content boxes. Once this has been approved you will find the sign off of design much easier.

8. Present your designs

Although it is true that a good design should speak for itself it still needs presenting to the client. The client needs to understand why you have made the design decisions you have, otherwise they will judge the design purely on personal preference. 

Talk them through the design explaining how it meets the needs of their users and business objectives. Refer to the mood boards and preferred sites the client approved and explain how the design is a continuation of those. Never simply email the design through and hope the client interprets your work correctly!

9. Provide written supporting material

Unfortunately, no matter how well you justify the design to the client he is almost certain to want to show it to others. He may need his bosses approval or require internal buy in. At the very least he is going to want to get a second opinion from a friend or colleague.

The problem with this is that you are not going to be there to present to these people in the same way you did for the client. You cannot expect the client to present your ideas as well as you did. The reality is that you have lost control of how the design is perceived.

One way to minimize this problem is to provide written documentation supporting the design. This can be a summary of the presentation you gave to the client and allows him to distribute this along with the design. By putting a written explanation with the design you ensure that everybody who sees it gets the same message.

10. Control the feedback

My final piece of advice for managing design sign off is to control the way you receive feedback. A clients natural inclination will be to give you his personal opinion on the design. This is reinforced because you ask them what they think of the design. Instead ask them what their users will think of the design. Encourage them to think from the users perspective.

Also encourage them to keep that overarching focus I talked about in my first tip. Their tendency will be to try to improve the design, however that should be your problem not theirs. The role of a client should be to defend the needs of their users and business not do the design. Encourage the client to make comments such as “I am not sure that my female users will like the masculine colours” rather than “can we make the whole design pink.” It is down to them to identify the problems and for you as the designer to find the most appropriate solution.

So there you have it. My 10 tips to improve design sign off. Will this ensure design approval every time? Unfortunately not. However it should certainly help smooth the way.",2007,Paul Boag,paulboag,2007-12-10T00:00:00+00:00,https://24ways.org/2007/10-ways-to-get-design-approval/,business
124,Writing Responsible JavaScript,"Without a doubt, JavaScript has been making something of a comeback in the last year. If you’re involved in client-side development in any way at all, chances are that you’re finding yourself writing more JavaScript now than you have in a long time.

If you learned most of your JavaScript back when DHTML was all the rage and before DOM Scripting was in vogue, there have been some big shifts in the way scripts are written. Most of these are in the way event handlers are assigned and functions declared. Both of these changes are driven by the desire to write scripts that are responsible page citizens, both in not tying behaviour to content and in taking care not to conflict with other scripts. I thought it may be useful to look at some of these more responsible approaches to learn how to best write scripts that are independent of the page content and are safely portable between different applications.

Event Handling

Back in the heady days of Web 1.0, if you wanted to have an object on the page react to something like a click, you would simply go ahead and attach an onclick attribute. This was easy and understandable, but much like the font tag or the style attribute, it has the downside of mixing behaviour or presentation in with our content. As we’re learned with CSS, there are big benefits in keeping those layers separate. Hey, if it works for CSS, it should work for JavaScript too.

Just like with CSS, instead of adding an attribute to our element within the document, the more responsible way to do that is to look for the item from your script (like CSS does with a selector) and then assign the behaviour to it. To give an example, take this oldskool onclick use case:

<a id=""anim-link"" href=""#"" onclick=""playAnimation()"">Play the animation</a>

This could be rewritten by removing the onclick attribute, and instead doing the following from within your JavaScript.

document.getElementById('anim-link').onclick = playAnimation;

It’s all in the timing

Of course, it’s never quite that easy. To be able to attach that onclick, the element you’re targeting has to exist in the page, and the page has to have finished loading for the DOM to be available. This is where the onload event is handy, as it fires once everything has finished loading. Common practise is to have a function called something like init() (short for initialise) that sets up all these event handlers as soon as the page is ready.

Back in the day we would have used the onload attibute on the <body> element to do this, but of course what we really want is:

window.onload = init;

As an interesting side note, we’re using init here rather than init() so that the function is assigned to the event. If we used the parentheses, the init function would have been run at that moment, and the result of running the function (rather than the function itself) would be assigned to the event. Subtle, but important.

As is becoming apparent, nothing is ever simple, and we can’t just go around assigning our initialisation function to window.onload. What if we’re using other scripts in the page that might also want to listen out for that event? Whichever script got there last would overwrite everything that came before it. To manage this, we need a script that checks for any existing event handlers, and adds the new handler to it. Most of the JavaScript libraries have their own systems for doing this. If you’re not using a library, Simon Willison has a good stand-alone example

function addLoadEvent(func) {
	var oldonload = window.onload;
	if (typeof window.onload != 'function') {
		window.onload = func;
	} else {
		window.onload = function() {
			if (oldonload) {
				oldonload();
			}
			func();
		}
	}
}

Obviously this is just a toe in the events model’s complex waters. Some good further reading is PPK’s Introduction to Events.

Carving out your own space

Another problem that rears its ugly head when combining multiple scripts on a single page is that of making sure that the scripts don’t conflict. One big part of that is ensuring that no two scripts are trying to create functions or variables with the same names. Reusing a name in JavaScript just over-writes whatever was there before it.

When you create a function in JavaScript, you’ll be familiar with doing something like this.

function foo() {
	... goodness ...
}

This is actually just creating a variable called foo and assigning a function to it. It’s essentially the same as the following.

var foo = function() {
	... goodness ...
}

This name foo is by default created in what’s known as the ‘global namespace’ – the general pool of variables within the page. You can quickly see that if two scripts use foo as a name, they will conflict because they’re both creating those variables in the global namespace.

A good solution to this problem is to add just one name into the global namespace, make that one item either a function or an object, and then add everything else you need inside that. This takes advantage of JavaScript’s variable scoping to contain you mess and stop it interfering with anyone else.

Creating An Object

Say I was wanting to write a bunch of functions specifically for using on a site called ‘Foo Online’. I’d want to create my own object with a name I think is likely to be unique to me.

var FOOONLINE = {};

We can then start assigning functions are variables to it like so:

FOOONLINE.message = 'Merry Christmas!';
FOOONLINE.showMessage = function() {
	alert(this.message);
};

Calling FOOONLINE.showMessage() in this example would alert out our seasonal greeting. The exact same thing could also be expressed in the following way, using the object literal syntax.

var FOOONLINE = {
	message: 'Merry Christmas!',
	showMessage: function() {
		alert(this.message);
	}
};

Creating A Function to Create An Object

We can extend this idea bit further by using a function that we run in place to return an object. The end result is the same, but this time we can use closures to give us something like private methods and properties of our object.

var FOOONLINE = function(){
	var message = 'Merry Christmas!';
	return {
		showMessage: function(){
			alert(message);
		}
	}
}();

There are two important things to note here. The first is the parentheses at the end of line 10. Just as we saw earlier, this runs the function in place and causes its result to be assigned. In this case the result of our function is the object that is returned at line 4.

The second important thing to note is the use of the var keyword on line 2. This ensures that the message variable is created inside the scope of the function and not in the global namespace. Because of the way closure works (which if you’re not familiar with, just suspend your disbelief for a moment) that message variable is visible to everything inside the function but not outside. Trying to read FOOONLINE.message from the page would return undefined.

This is useful for simulating the concept of private class methods and properties that exist in other programming languages. I like to take the approach of making everything private unless I know it’s going to be needed from outside, as it makes the interface into your code a lot clearer for someone else to read. 

All Change, Please

So that was just a whistle-stop tour of a couple of the bigger changes that can help to make your scripts better page citizens. I hope it makes useful Sunday reading, but obviously this is only the tip of the iceberg when it comes to designing modular, reusable code.

For some, this is all familiar ground already. If that’s the case, I encourage you to perhaps submit a comment with any useful resources you’ve found that might help others get up to speed. Ultimately it’s in all of our interests to make sure that all our JavaScript interoperates well – share your tips.",2006,Drew McLellan,drewmclellan,2006-12-10T00:00:00+00:00,https://24ways.org/2006/writing-responsible-javascript/,code
144,"The Mobile Web, Simplified","A note from the editors:  although eye-opening in 2006, this article is no longer relevant to today’s mobile web.
                
                
                      
                Considering a foray into mobile web development? Following are four things you need to know before making the leap.

1. 4 billion mobile subscribers expected by 2010

Fancy that. Coupled with the UN prediction of 6.8 billion humans by 2010, 4 billion mobile subscribers (source) is an astounding 59% of the planet. Just how many of those subscribers will have data plans and web-enabled phones is still in question, but inevitably this all means one thing for you and me: A ton of potential eyes to view our web content on a mobile device.

2. Context is king

Your content is of little value to users if it ignores the context in which it is viewed. Consider how you access data on your mobile device.  You might be holding a bottle of water or gripping a handle on the subway/tube. You’re probably seeking specific data such as directions or show times, rather than the plethora of data at your disposal via a desktop PC.

The mobile web, a phrase often used to indicate “accessing the web on a mobile device”,  is very much a context-, content-, and component-specific environment. Expressed in terms of your potential target audience, access to web content on a mobile device is largely influenced by surrounding circumstances and conditions, information relevant to being mobile, and the feature set of the device being used. Ask yourself, What is relevant to my users and the tasks, problems, and needs they may encounter while being mobile? Answer that question and you’ll be off to a great start.

3. WAP 2.0 is an XHTML environment

In a nutshell, here are a few fundamental tenets of mobile internet technology:


	Wireless Application Protocol (WAP) is the protocol for enabling mobile access to internet content.
	Wireless Markup Language (WML) was the language of choice for WAP 1.0.
	Nearly all devices sold today are WAP 2.0 devices.
	With the introduction of WAP 2.0, XHTML Mobile Profile (XHTML-MP) became the preferred markup language.
	XHTML-MP will be familiar to anyone experienced with XHTML Transitional or Strict.


Summary? The mobile web is rapidly becoming an XHTML environment, and thus you and I can apply our existing “desktop web” skills to understand how to develop content for it. With WML on the decline, the learning curve is much smaller today than it was several years ago. I’m generalizing things gratuitously, but the point remains: Get off yo’ lazy butt and begin to take mobile seriously.

I’ll even pass you a few tips for getting started. First, the DOCTYPE for XHTML-MP is as follows:

<!DOCTYPE html PUBLIC ""-//WAPFORUM//DTD XHTML Mobile 1.0//EN""
""http://www.openmobilealliance.org/tech/DTD/xhtml-mobile10.dtd"">

As for MIME type, Open Mobile Alliance (OMA) specifies using the MIME type application/vnd.wap.xhtml+xml, but ultimately you need to ensure the server delivering your mobile content is configured properly for the MIME type you choose to use, as there are other options (see Setting up WAP Servers).

Once you’ve made it to the body, the XHTML-MP markup is not unlike what you’re already used to. A few resources worth skimming:


	Developers Home XHTML-MP Tutorial – An impressively replete resource for all things XHTML-MP
	XHTML-MP Tags List – A complete list of XHTML-MP elements and accompanying attributes


And last but certainly not least, CSS. There exists WAP CSS, which is essentially a subset of CSS2 with WAP-specific extensions. For all intents and purposes, much of the CSS you’re already comfortable using will be transferrable to mobile. As for including CSS in your pages, your options are the same as for desktop sites: external, embedded, and inline. Some experts will argue embedded or inline over external in favor of reducing the number of HTTP connections per page request, yet many popular mobilized sites and apps employ external linking without issue.

Stocking stuffers: Flickr Mobile, Fandango Mobile, and Popurls Mobile. A few sites with whom you can do the View Source song and dance for further study.

4. “Cell phone” is so DynaTAC

If you’re a U.S. resident, listen up: You must rid your vocabulary of the term “cell phone”. We’re one of the few economies on the planet to refer to a mobile phone accordingly. If you care to find yourself in any of the worthwhile mobile development circles, begin using terms more widely accepted: “mobile” or “mobile phone” or “handset” or “handy”. If you’re not sure which, go for “mobile”. Such as, “Yo dog, check out my new mobile.”

More importantly, however, is overcoming the mentality that access to the mobile web can be done only with a phone. Instead, “device” encourages us to think phone, handheld computer, watch, Nintendo DS, car, you name it.

Simple enough?",2006,Cameron Moll,cameronmoll,2006-12-19T00:00:00+00:00,https://24ways.org/2006/the-mobile-web-simplified/,ux
132,Tasty Text Trimmer,"In most cases, when designing a user interface it’s best to make a decision about how data is best displayed and stick with it. Failing to make a decision ultimately leads to too many user options, which in turn can be taxing on the poor old user. 

Under some circumstances, however, it’s good to give the user freedom in customising their workspace. One good example of this is the ‘Article Length’ tool in Apple’s Safari RSS reader. Sliding a slider left of right dynamically changes the length of each article shown. It’s that kind of awesomey magic stuff that’s enough to keep you from sleeping. Let’s build one.

The Setup

Let’s take a page that has lots of long text items, a bit like a news page or like Safari’s RSS items view. If we were to attach a class name to each element we wanted to resize, that would give us something to hook onto from the JavaScript. 

Example 1: The basic page.

As you can see, I’ve wrapped my items in a DIV and added a class name of chunk to them. It’s these chunks that we’ll be finding with the JavaScript. Speaking of which …

Our Core Functions

There are two main tasks that need performing in our script. The first is to find the chunks we’re going to be resizing and store their original contents away somewhere safe. We’ll need this so that if we trim the text down we’ll know what it was if the user decides they want it back again. We’ll call this loadChunks. 

var loadChunks = function(){
	var everything = document.getElementsByTagName('*');
	var i, l;
	chunks	= [];
	for (i=0, l=everything.length; i<l; i++){
		if (everything[i].className.indexOf(chunkClass) > -1){
			chunks.push({
				ref: everything[i],
				original: everything[i].innerHTML
			});
		}
	}
};

The variable chunks is stored outside of this function so that we can access it from our next core function, which is doTrim.

var doTrim = function(interval) {
	if (!chunks) loadChunks();
	var i, l;
	for (i=0, l=chunks.length; i<l; i++){
		var a = chunks[i].original.split(' ');
		a = a.slice(0, interval);
		chunks[i].ref.innerHTML	= a.join(' ');
	}
};

The first thing that needs to be done is to call loadChunks if the chunks variable isn’t set. This should only happen the first time doTrim is called, as from that point the chunks will be loaded.

Then all we do is loop through the chunks and trim them. The trimming itself (lines 6-8) is very simple. We split the text into an array of words (line 6), then select only a portion from the beginning of the array up until the number we want (line 7). Finally the words are glued back together (line 8).

In essense, that’s it, but it leaves us needing to know how to get the number into this function in the first place, and how that number is generated by the user. Let’s look at the latter case first.

The YUI Slider Widget

There are lots of JavaScript libraries available at the moment. A fair few of those are really good. I use the Yahoo! User Interface Library professionally, but have only recently played with their pre-build slider widget. Turns out, it’s pretty good and perfect for this task. 

Once you have the library files linked in (check the docs linked above) it’s fairly straightforward to create yourself a slider.

slider = YAHOO.widget.Slider.getHorizSlider(""sliderbg"", ""sliderthumb"", 0, 100, 5); 
slider.setValue(50);
slider.subscribe(""change"", doTrim);

All that’s needed then is some CSS to make the slider look like a slider, and of course a few bits of HTML. We’ll see those later.

See It Working!

Rather than spell out all the nuts and bolts of implementing this fairly simple script, let’s just look at in it action and then pick on some interesting bits I’ve added.

Example 2: Try the Tasty Text Trimmer.

At the top of the JavaScript file I’ve added a small number of settings.

var chunkClass	= 'chunk';
var minValue	= 10;
var maxValue	= 100;
var multiplier	= 5;

Obvious candidates for configuration are the class name used to find the chunks, and also the some minimum and maximum values. The minValue is the fewest number of words we wish to display when the slider is all the way down. The maxValue is the length of the slider, in this case 100.

Moving the slider makes a call to our doTrim function with the current value of the slider. For a slider 100 pixels long, this is going to be in the range of 0-100. That might be okay for some things, but for longer items of text you’ll want to allow for displaying more than 100 words. I’ve accounted for this by adding in a multiplier – in my code I’m multiplying the value by 5, so a slider value of 50 shows 250 words. You’ll probably want to tailor the multiplier to the type of content you’re using.

Keeping it Accessible 

This effect isn’t something we can really achieve without JavaScript, but even so we must make sure that this functionality has no adverse impact on the page when JavaScript isn’t available. This is achieved by adding the slider markup to the page from within the insertSliderHTML function.

var insertSliderHTML = function(){
	var s = '<a id=""slider-less"" href=""#less""><img src=""icon_min.gif"" width=""10"" height=""10"" alt=""Less text"" class=""first"" /></a>';
	s +=' <div id=""sliderbg""><div id=""sliderthumb""><img src=""sliderthumbimg.gif"" /></div></div>';
	s +=' <a id=""slider-more"" href=""#more""><img src=""icon_max.gif"" width=""10"" height=""10"" alt=""More text"" /></a>';
	document.getElementById('slider').innerHTML = s;
}

The other important factor to consider is that a slider can be tricky to use unless you have good eyesight and pretty well controlled motor skills. Therefore we should provide a method of changing the value by the keyboard.

I’ve done this by making the icons at either end of the slider links so they can be tabbed to. Clicking on either icon fires the appropriate JavaScript function to show more or less of the text.

In Conclusion

The upshot of all this is that without JavaScript the page just shows all the text as it normally would. With JavaScript we have a slider for trimming the text excepts that can be controlled with the mouse or with a keyboard.

140,Styling hCards with CSS,"There are plenty of places online where you can learn about using the hCard microformat to mark up contact details at your site (there are some resources at the end of the article). But there’s not yet been a lot of focus on using microformats with CSS. So in this installment of 24 ways, we’re going to look at just that – how microformats help make CSS based styling simpler and more logical.

Being rich, quite complex structures, hCards provide designers with a sophisticated scaffolding for styling them. A recent example of styling hCards I saw, playing on the business card metaphor, was by Andy Hume, at http://thedredge.org/2005/06/using-hcards-in-your-blog/. While his approach uses fixed width cards, let’s take a look at how we might style a variable width business card style for our hCards.

Let’s take a common hCard, which includes address, telephone and email details

We’ll be using a variation on the now well established “sliding doors” technique (if you create a CSS technique, remember it’s very important to give it a memorable name or acronym, and bonus points if you get your name in there!) by Douglas Bowman, enhanced by Scott Schiller (see http://www.schillmania.com/projects/dialog/,) which will give us a design which looks like this



The technique, in a nutshell, uses background images on four elements, two at the top, and two at the bottom, to add each rounded corner.

We are going to make this design “fluid” in the sense that it grows and shrinks in proportion with the size of the font that the text of the element is displayed with. This is sometimes referred to as an “em driven design” (we’ll see why in a moment).

To see how this works in practice, here’s the same design with the text “zoomed” up in size



and the same design again, when we zoom the text size down



By the way, the hCard image comes from Chris Messina, and you can download it and other microformat icons from the microformats wiki.

Now, with CSS3, this whole task would be considerably easier, because we can add multiple background images to an element, and border images for each edge of an element. Safari, version 1.3 up, actually supports multiple background images, but sadly, it’s not supported in Firefox 1.5, or even Firefox 2.0 (let’s not mention IE7 eh?). So it’s probably too little supported to use now. So instead we’ll use a technique that only involves CSS2, and works in pretty much any browser.

Very often, developers add div or span elements as containers for these background images, and in fact, if you visit Scott Shiller’s site, that’s what he has done there. But if at all possible we shouldn’t be adding any HTML simply for presentational purposes, even if the presentation is done via CSS. What we can do is to use the HTML we have already, as much as is possible, to add the style we want. This can take some creative thinking, but once you get the hang of this approach it becomes a more natural way of using HTML compared with simply adding divs and spans at will as hooks for style. Of course, this technique isn’t always simple, and in fact sometimes simply not possible, requiring us to add just a little HTML to provide the “hooks” for CSS.

Let’s go to work

The first step is to add a background image to the whole vCard element.



We make this wide enough (for example 1000 or more pixels) and tall enough that no matter how large the content of the vCard grows, it will never overflow this area. We can’t simply repeat the image, because the top left corner will show when the image repeats.

We add this as the background image of the vCard element using CSS.

While we are at it, let’s give the text a sans-serif font, some color so that it will be visible, and stop the image repeating.

.vcard {
	background-image: url(images/vcardfill.png);
	background-repeat: no-repeat;
	color: #666;
	font-family: ""Lucida Grande"", Verdana, Helvetica, Arial, sans-serif;
}

Which in a browser, will look something like this.



Next step we need to add the top right hand corner of the hCard. In keeping with our aim of not adding HTML simply for styling purposes, we want to use the existing structure of the page where possible. Here, we’ll use the paragraph of class fn and org, which is the first child element of the vcard element.

<p class=""fn org"">Web Directions Conference Pty Ltd <img src=""images/vcard-add.png"" alt=""download vcard icon""></p>

Here’s our CSS for this element

.fn {
	background-image: url(images/topright.png);
	background-repeat: no-repeat;
	background-position: top right;
	padding-top: 2em;
	font-weight: bold;
	font-size: 1.1em;
}

Again, we don’t want it to repeat, but this time, we’ve specified a background position for the image. This will make the background image start from the top, but its right edge will be located at the right edge of the element. I also made the font size a little bigger, and the weight bold, to differentiate it from the rest of the text in the hCard.

Here’s the image we are adding as the background to this element.



So, putting these two CSS statements together we get



We specified a padding-top of 2em to give some space between the content of the fn element and the edge of the fn element. Otherwise the top of the hCard image would be hard against the border. To see this in action, just remove the padding-top: 2em; declaration and preview in a browser.

So, with just two statements, we are well under way. We’ve not even had to add any HTML so far. Let’s turn to the bottom of the element, and add the bottom border (well, the background image which will serve as that border).

Now, which element are we going to use to add this background image to?

OK, here I have to admit to a little, teensie bit of cheating. If you look at the HTML of the hCard, I’ve grouped the email and telephone properties into a div, with a class of telecommunications. This grouping is not strictly requred for our hCard.

<div class=""telecommunications"">
	<p class=""tel"">Phone/Fax: <span class=""tel""><span class=""type"">Work</span>:
		<span class=""value"">61 2 9365 5007</span></p>
	<p class=""email"">Email: <a class=""value"" href=""mailto:info@webdirections.org"">info@webdirections.org</a></p>
</div>

Now, I chose that class name because that is what the vCard specification calls this group of properties. And typically, I do tend to group together related elements using divs when I  mark up content. I find it makes the page structure more logical and readable. But strictly speaking, this isn’t necessary, so you may consider it cheating. But my lesson in this would be, if you are going to add markup, try to make it as meaningful as possible.

As you have probably guessed by now, we are going to add one part of the bottom border image to this element. We’re going to add this image as the background-image.



Again, it will be a very wide image, like the top left one, so that no matter how wide the element might get, the background image will still be wide enough. Now, we’ll need to make this image sit in the bottom left of the element we attach it to, so we use a backgound position of left bottom (we put the horizontal position before the vertical). Here’s our CSS statement for this

.telecommunications {
	background-image: url(images/bottom-left.png);
	background-repeat: no-repeat;
	background-position: left bottom;
	margin-bottom: 2em;
}

And that will look like this



Not quite there, but well on the way. Time for the final piece in the puzzle.

OK, I admit, I might have cheated just a little bit more in this step. But like the previous step, all valid, and (hopefully) quite justifiable markup. If we look at the HTML again, you’ll find that our email address is marked up like this

<p class=""email"">Email: <a class=""value"" href=""mailto:info@webdirections.org"">info@webdirections.org</a></p>

Typically, in hCard, the value part of this property isn’t required, and we could get away with

<a class=""email"" href=""mailto:info@webdirections.org"">info@webdirections.org</a>

The form I’ve used, with the span of class value is however, perfectly valid hCard markup (hard allows for multiple email addresses of different types, which is where this typically comes in handy). Why have I gone to all this trouble? Well, when it came to styling the hCard, I realized I needed a block element to attach the background image for the bottom right hand corner to. Typically the last block element in the containing element is the ideal choice (and sometimes it’s possible to take an inline element, for example the link here, and use CSS to make it a block element, and attach it to that, but that really doesn’t work with this design).

So, if we are going to use the paragraph which contains the email link, we need a way to select it exclusively, which means that with CSS2 at least, we need a class or id as a hook for our CSS selector (in CSS3 we could use the last-child selector, which selects the last child element of a specified element, but again, as last child is not widely supported, we won’t rely on it here.)

So, the least worst thing we could do is take an existing element, and add some reasonably meaningful markup to it. That’s why we gave the paragraph a class of email, and the email address a class of value. Which reminds me a little of a moment in Hamlet


	The lady doth protest too much, methinks


OK, let’s get back to the CSS.

We add the bottom right corner image, positioning it in the bottom right of the element, and making sure it doesn’t repeat. We also add some padding to the bottom, to balance out the padding we added to the top of the hCard.

p.email {
	background-image: url(images/bottom-right.png);
	background-position: right bottom;
	background-repeat: no-repeat;
	padding-bottom: 2em;
}

Which all goes to make our hCard look like this



It just remains for us to clean up a little.

Let’s start from the top. We’ll float the download image to the right like this

.vcard img {
	float: right;
	padding-right: 1em;
	margin-top: -1em
}

See how we didn’t have to add a class to style the image, we used the  fact that the image is a descendent of the vcard element, and a descendent selector. In my experience, the very widely supported, powerful descendent selector is one of the most underused aspects of CSS. So if you don’t use it frequently, look into it in more detail.

We added some space to the right of the image, and pulled it up a bit closer to the top of the hCard, like this



We also want to add some whitespace between the edge of the hCard and the text. We would typically add padding to the left of the containing element, (in this case the vcard element) but this would break our bottom left hand corner, like this



That’s because the div element we added this bottom left background image to would be moved in by the padding on its containing element.

So instead, we add left margin to all the paragraphs in the hCard

.vcard p {
	margin-left: 1em;
}

(there is the descendent selector again – it is the swiss army knife of CSS)

Now, we’ve not yet made the width of the hCard a function of the size of the text inside it (or “em driven” as we described it earlier). We do this by giving the hCard a width that is specified in em units. Here we’ll set a width of say 28em, which makes the hCard always roughly as wide as 28 characters (strictly speaking 28 times the width of the letter capital M). 

So the statement for our containing vcard element becomes

.vcard {
	background-image: url(images/vcardfill.png);
	background-repeat: no-repeat;
	color: #666;
	font-family: ""Lucida Grande"", Verdana, Helvetica, Arial, sans-serif;
	width: 28em;
}

and now our element will look like this



We’ve used almost entirely the existing HTML from our original hCard (adding just a little, and trying as much as possible to keep that additional markup meaningful), and just 6 CSS statements.

Holiday Bonus – a downloadable vCard

Did you notice this part of the HTML

<a href=""http://suda.co.uk/projects/X2V/get-vcard.php?uri=http://north.webdirections.org/contact/"">
        <img src=""images/vcard-add.png"" alt=""download vcard icon""></a>

What’s with the odd looking url

<a href=""http://suda.co.uk/projects/X2V/get-vcard.php?uri=http://north.webdirections.org/contact/""

If you click the link, X2V, a nifty web service from Brian Suda, grabs the page at the URL, and if it finds a hCard, converts it to a vCard, and depending on how your system is setup, automatically downloads it and adds it to your address book (Mac OS X) or prompts you whether you’d like to save the vCard and add it to whatever application is the default vCard handler on your system. 

What X2V does is take the actual HTML of your hCard, and with the magic of XSLT, converts it to a vCard. So, by simply marking up contact details using hCard, and adding a link like this, you automatically get downloadable vCard – and if you change your contact details, and update the hCard, there’s no vCard file to update as well.

Technorati also have a similar service at http://technorati.com/contact so you might want to use that if you expect any kind of load, as they can probably afford the bandwidth more than Brian!

If you want to play with the HTML and CSS for this design, the code and images can be downloaded.

Hope you enjoyed this, and found it useful. If so, you might like to check out my microformats focussed blog, or get along to Web Directions North, where I’ll be speaking along with Dan Cederholmn and Tantek Çelik in a 2 hour session focussed solely on microformats.

A happy festive season, and all the best for 2007

127,Showing Good Form,"Earlier this year, I forget exactly when (it’s been a good year), I was building a client site that needed widgets which look like this (designed, incidentally, by my erstwhile writing partner, Cameron Adams):



Building this was a challenge not just in CSS, but in choosing the proper markup – how should such a widget be constructed?

Mmm … markup

It seemed to me there were two key issues to deal with:


	The function of the interface is to input information, so semantically this is a form, therefore we have to find a way of building it using form elements: fieldset, legend, label and input
	We can’t use a table for layout, even though that would clearly be the easiest solution!


Abusing tables for layout is never good – physical layout is not what table semantics mean. But even if this data can be described as a table, we shouldn’t mix forms markup with non-forms markup, because of the behavioral impact this can have on a screen reader:

To take a prominent example, the screen reader JAWS has a mode specifically for interacting with forms (cunningly known as “forms mode”). When running in this mode its output only includes relevant elements – legends, labels and form controls themselves. Any other kind of markup – like text in a previous table cell, a paragraph or list in between – is simply ignored. The user in this situation would have to switch continually in and out of forms mode to hear all the content. (For more about this issue and some test examples, there’s a  thread at accessify forum which wanders in that direction.)

One further issue for screen reader users is implied by the design: the input fields are associated together in rows and columns, and a sighted user can visually scan across and down to make those associations; but a blind user can’t do that. For such a user the row and column header data will need to be there at every axis; in other words, the layout should be more like this:



And constructed with appropriate semantic markup to convey those relationships. By this point the selection of elements seems pretty clear: each row is a fieldset, the row header is a legend, and each column header is a label, associated with an input.

Here’s what that form looks like with no CSS:



And here’s some markup for the first row (with most of the attributes removed just to keep this example succinct):

<fieldset>
	<legend>
		<span>Match points</span>
	</legend>
	<label>
		<span>Win</span>
		<input value=""3"" />
	</label>
	<label>
		<span>Draw</span>
		<input value=""1"" />
	</label>
	<label>
		<span>Lose</span>
		<input value=""0"" />
	</label>
	<label>
		<span>Played</span>
		<input value=""0"" />
	</label>
</fieldset>

The span inside each legend is because legend elements are highly resistant to styling! Indeed they’re one of the most stubborn elements in the browsers’ vocabulary. Oh man … how I wrestled with the buggers … until this obvious alternative occurred to me! So the legend element itself is just a container, while all the styling is on the inner span.

Oh yeah, there was some CSS too

I’m not gonna dwell too much on the CSS it took to make this work – this is a short article, and it’s all there in the demo [demo page, style sheet]

But I do want to touch on the most interesting bit – where we get from a layout with headers on every row, to one where only the top row has headers – or at least, so it appears to graphical browsers. For screen readers, as we noted, we need those headers on every row, so we should employ some cunning CSS to partly negate their visual presence, without removing them from the output.

The core styling for each label span is like this:

label span
{
	display:block;
	padding:5px;
	line-height:1em;
	background:#423221;
	color:#fff;
	font-weight:bold;
}

But in the rows below the header they have these additional rules:

fieldset.body label span
{
	padding:0 5px;
	line-height:0;
	position:relative;
	top:-10000em;
}

The rendered width of the element is preserved, ensuring that the surrounding label is still the same width as the one in the header row above, and hence a unified column width is preserved all the way down. But the element effectively has no height, and so it’s effectively invisible. The styling is done this way, rather than just setting the height to zero and using overflow:hidden, because to do that would expose an unrelated quirk with another popular screen reader! (It would hide the output from Window Eyes, as shown in this  test example at access matters.)

The finished widget

It’s an intricate beast allright! But after all that we do indeed get the widget we want:


	Demo page
	Style sheet


It’s not perfect, most notably because the legends have to have a fixed width; this can be in em to allow for text scaling, but it still doesn’t allow the content to break into multiple lines. It also doesn’t look quite right in Safari; and some CSS hacking was needed to make it look right in IE6 and IE7.

Still it worked well enough for the purpose, and satisfied the client completely. And most of all it re-assured me in my faith – that there’s never any need to abuse tables for layout. (Unless of course you think this content is a table anyway, but that’s another story!)",2006,James Edwards,jamesedwards,2006-12-11T00:00:00+00:00,https://24ways.org/2006/showing-good-form/,ux
138,Rounded Corner Boxes the CSS3 Way,"If you’ve been doing CSS for a while you’ll know that there are approximately 3,762 ways to create a rounded corner box. The simplest techniques rely on the addition of extra mark-up directly to your page, while the more complicated ones add the mark-up though DOM manipulation. While these techniques are all very interesting, they do seem somewhat of a kludge. The goal of CSS is to separate structure from presentation, yet here we are adding superfluous mark-up to our code in order to create a visual effect. The reason we are doing this is simple. CSS2.1 only allows a single background image per element.

Thankfully this looks set to change with the addition of multiple background images into the CSS3 specification. With CSS3 you’ll be able to add not one, not four, but eight background images to a single element. This means you’ll be able to create all kinds of interesting effects without the need of those additional elements.

While the CSS working group still seem to be arguing over the exact syntax, Dave Hyatt went ahead and implemented the currently suggested mechanism into Safari. The technique is fiendishly simple, and I think we’ll all be a lot better off once the W3C stop arguing over the details and allow browser vendors to get on and provide the tools we need to build better websites.

To create a CSS3 rounded corner box, simply start with your box element and apply your 4 corner images, separated by commas.

.box {
	background-image: url(top-left.gif), url(top-right.gif), url(bottom-left.gif), url(bottom-right.gif);
}

We don’t want these background images to repeat, which is the normal behaviour, so lets set all their background-repeat properties to no-repeat.

.box {
	background-image: url(top-left.gif), url(top-right.gif), url(bottom-left.gif), url(bottom-right.gif);
	background-repeat: no-repeat, no-repeat, no-repeat, no-repeat;
}

Lastly, we need to define the positioning of each corner image.

.box {
	background-image: url(top-left.gif), url(top-right.gif), url(bottom-left.gif), url(bottom-right.gif);
	background-repeat: no-repeat, no-repeat, no-repeat, no-repeat;
	background-position: top left, top right, bottom left, bottom right;
}

And there we have it, a simple rounded corner box with no additional mark-up.

As well as using multiple background images, CSS3 also has the ability to create rounded corners without the need of any images at all. You can do this by setting the border-radius property to your desired value as seen in the next example.

.box {
	border-radius: 1.6em;
}

This technique currently works in Firefox/Camino and creates a nice, if somewhat jagged rounded corner. If you want to create a box that works in both Mozilla and WebKit based browsers, why not combine both techniques and see what happens.",2006,Andy Budd,andybudd,2006-12-04T00:00:00+00:00,https://24ways.org/2006/rounded-corner-boxes-the-css3-way/,code
142,Revealing Relationships Can Be Good Form,"A few days ago, a colleague of mine – someone I have known for several years, who has been doing web design for several years and harks back from the early days of ZDNet – was running through a prototype I had put together for some user testing. As with a lot of prototypes, there was an element of ‘smoke and mirrors’ to make things look like they were working. 

One part of the form included a yes/no radio button, and selecting the Yes option would, in the real and final version of the form, reveal some extra content. Rather than put too much JavaScript in the prototype, I took a preverbial shortcut and created a link which I wrapped around the text next to the radio button – clicking on that link would cause the form to mimic a change event on the radio button. But it wasn’t working for him. 

Why was that? Because whereas I created the form using a <label> tag for each <input> and naturally went to click on the text rather than the form control itself, he was going straight for the control (and missing the sneaky little <a href> I’d placed around the text). Bah! There goes my time-saver.

So, what did I learn? That a web professional who has used the Internet for years had neither heard of the <label> tag, nor had he ever tried clicking on the text. It just goes to show that despite its obvious uses, the label element is not as well known as it rightfully deserves to be. So, what’s a web-standards-loving guy to do? Make a bit more bleedin’ obvious, that’s what! 

The Mouse Pointer Trick

OK, this is the kind of thing that causes some people outrage. A dead simple way of indicating that the label does something is to use a snippet of CSS to change the default mouse cursor to a hand. It’s derided because the hand icon is usually used for links, and some would argue that using this technique is misleading:

label {
	cursor: pointer;
}

This is not a new idea, though, and you didn’t come here for this. The point is that with something very simple, you’ve made the label element discoverable. But there are other ways that you can do this that are web standards friendly and won’t upset the purists quite so much as the hand/pointer trick. Time to wheel in the JavaScript trolley jack …

Our Old Friend AddEvent

First things, first, you’ll need to use the addEvent function (or your favourite variation thereof) that Scott Andrew devised and make that available to the document containing the form:

function addEvent(elm, evType, fn, useCapture)
{
	if(elm.addEventListener)
	{
		elm.addEventListener(evType, fn, useCapture);
		return true;
	}
	else if (elm.attachEvent)
	{
		var r = elm.attachEvent('on' + evType, fn);
		return r;
	}
	else
	{
		elm['on' + evType] = fn;
	}
}

Finding All Your Labels

Once you’ve linked to the addEvent function (or embedded it on the page), you can start to get your JavaScripting fingers a-flexing. Now, what I’m suggesting you do here is:


	Identify all the label elements on the page by working your way through the DOM
	Find out the value of the for attribute for each label that you uncover
	Attach a behaviour or two to each of those label elements – and to the input that the label relates to (identified with the for attribute)


Here’s the technobabble version of the steps above:

function findLabels()
{
	var el = document.getElementsByTagName(""label"");
	for (i=0;i<el.length;i++)
	{
		var thisId = el[i].getAttribute(""for"");
		if ((thisId)==null)
		{
			thisId = el[i].htmlFor;
		}
		if(thisId!="""")
		{
			//apply these behaviours to the label
			el[i].onmouseover = highlightRelationship;
			el[i].onmouseout = hideRelationship;
		}
	}
}
function highlightRelationship()
{
	var thisId = this.getAttribute(""for"");
	if ((thisId)==null)
	{
		thisId = this.htmlFor;
	}	
	this.className=""showRel"";
	document.getElementById(thisId).className=""showRel"";
	//if (document.getElementById(thisId).type==""text"") document.getElementById(thisId).select();
}
function hideRelationship()
{
	var thisId = this.getAttribute(""for"");
	if ((thisId)==null)
	{
		thisId = this.htmlFor;
	}	
	this.className="""";
	document.getElementById(thisId).className="""";
}
addEvent(window, 'load', findLabels, false);

Using the above script, you can apply a CSS class (I’ve called it showRel) to the elements when you hover over them. How you want it to look is up to you, of course. Here are a few examples of the idea. Note: the design is not exactly what you’d call ‘fancy’, and in the examples there is one input that looks broken but it is deliberately moved away from the label it relates to, just to demonstrate that you can show the relationship even from afar.

131,Random Lines Made With Mesh,"I know that Adobe Illustrator can be a bit daunting for people who aren’t really advanced users of the program, but you would be amazed by how easy you can create cool effects or backgrounds. In this short tutorial I show you how to create a cool looking background only in 5 steps. 

Step 1 – Create Lines



Create lines using random widths and harmonious suitable colors. If you get stuck on finding the right colors, check out Adobe’s Kuler and start experimenting.

Step 2 – Convert Strokes to Fills



Select all lines and convert them to fills. Go to the Object menu, select Path > Outline Stroke. Select the Rectangle tool and draw 1 big rectangle on top the lines. Give the rectangle a suitable color. With the rectangle still selected, go to the Object menu, select Arrange > Send to Back.

Step 3 – Convert to Mesh



Select all objects by pressing the command key (for Mac users), control key (for Windows users) + the “a” key. Go to the Object menu and select the Envelope Distort > Make with Mesh option. Enter 2 rows and 2 columns. Check the preview box to see what happens and click the OK button.

Step 4 – Play Around with The Mesh Points 



Play around with the points of the mesh using the Direct Selection tool (the white arrow in the Toolbox). Click on the top right point of the mesh. Once you’re starting to drag hold down the shift key and move the point upwards. 



Now start dragging the bezier handles on the mesh to achieve the effect as shown in the above picture. Of course you can try out all kind of different effects here. 

The Final Result



This is an example of how the final result can look. You can try out all kinds of different shapes dragging the handles of the mesh points. This is just one of the many results you can get. So next time you haven’t got inspiration for a background of a header, a banner or whatever, just experiment with a few basic shapes such as lines and try out the ‘Envelope Distort’ options in Illustrator or the ‘Make with Mesh’ option and experiment, you’ll be amazed by the unexpected creative results.",2006,Veerle Pieters,veerlepieters,2006-12-08T00:00:00+00:00,https://24ways.org/2006/random-lines-made-with-mesh/,design
134,Photographic Palettes,"How many times have you seen a colour combination that just worked, a match so perfect that it just seems obvious? 

Now, how many times do you come up with those in your own work? A perfect palette looks easy when it’s done right, but it’s often maddeningly difficult and time-consuming to accomplish.

Choosing effective colour schemes will always be more art than science, but there are things you can do that will make coming up with that oh-so-smooth palette just a little a bit easier. A simple trick that can lead to incredibly gratifying results lies in finding a strong photograph and sampling out particularly harmonious colours.

Photo Selection

Not all photos are created equal. You certainly want to start with imagery that fits the eventual tone you’re attempting to create. A well-lit photo of flowers might lead to a poor colour scheme for a funeral parlour’s web site, for example. It’s worth thinking about what you’re trying to say in advance, and finding a photo that lends itself to your message.

As a general rule of thumb, photos that have a lot of neutral or de-saturated tones with one or two strong colours make for the best palette; bright and multi-coloured photos are harder to derive pleasing results from. Let’s start with a relatively neutral image.

Sampling



In the above example, I’ve surrounded the photo with three different background colours directly sampled from the photo itself. Moving from left to right, you can see how each of the sampled colours is from an area of increasingly smaller coverage within the photo, and yet there’s still a strong harmony between the photo and the background image. I don’t really need to pick the big obvious colours from the photo to create that match, I can easily concentrate on more interesting colours that might work better for what I intend.

Using a similar palette, let’s apply those colour choices to a more interesting layout:



In this mini-layout, I’ve re-used the same tan colour from the previous middle image as a background, and sampled out a nicely matching colour for the top and bottom overlays, as well as the two different text colours. Because these colours all fall within a narrow range, the overall balance is harmonious.

What if I want to try something a little more daring? I have a photo of stacked chairs of all different colours, and I’d like to use a few more of those. No problem, provided I watch my colour contrast:



Though it uses varying shades of red, green, and yellow, this palette actually works because the values are even, and the colours muted. Placing red on top of green is usually a hideous combination of death, but if the green is drab enough and the red contrasts well enough, the result can actually be quite pleasing. I’ve chosen red as my loudest colour in this palette, and left green and yellow to play the quiet supporting roles.

Obviously, there are no hard and fast rules here. You might not want to sample absolutely every colour in your scheme from a photo. There are times where you’ll need a variation that’s just a little bit lighter, or a blue that’s not in the photo. You might decide to start from a photo base and tweak, or add in colours of your own. That’s okay too.

Tonal Variations

I’ll leave you with a final trick I’ve been using lately, a way to bring a bit more of a formula into the equation and save some steps.



Starting with the same base palette I sampled from the chairs, in the above image I’ve added a pair of overlaying squares that produce tonal variations of each primary. The lighter variation is simply a solid white square set to 40% opacity, the darker one is a black square at 20%. That gives me a highlight and shadow for each colour, which would prove handy if I had to adapt this colour scheme to a larger layout.

I could add a few more squares of varying opacities, or adjust the layer blending modes for different effects, but as this looks like a great place to end, I’ll leave that up to your experimental whims.

143,Marking Up a Tag Cloud,"Everyone’s doing it. 

The problem is, everyone’s doing it wrong. 

Harsh words, you might think. But the crimes against decent markup are legion in this area. You see, I’m something of a markup and semantics junkie. So I’m going to analyse some of the more well-known tag clouds on the internet, explain what’s wrong, and then show you one way to do it better. 

del.icio.us 

I think the first ever tag cloud I saw was on del.icio.us. Here’s how they mark it up. 

<div class=""alphacloud"">
	<a href=""/tag/.net"" class=""lb s2"">.net</a>
	<a href=""/tag/advertising"" class="" s3"">advertising</a>
	<a href=""/tag/ajax"" class="" s5"">ajax</a>
	...
</div>

Unfortunately, that is one of the worst examples of tag cloud markup I have ever seen. The page states that a tag cloud is a list of tags where size reflects popularity. However, despite describing it in this way to the human readers, the page’s author hasn’t described it that way in the markup. It isn’t a list of tags, just a bunch of anchors in a <div>. This is also inaccessible because a screenreader will not pause between adjacent links, and in some configurations will not announce the individual links, but rather all of the tags will be read as just one link containing a whole bunch of words. Markup crime number one. 

Flickr 

Ah, Flickr. The darling photo sharing site of the internet, and the biggest blind spot in every standardista’s vision. Forgive it for having atrocious markup and sometimes confusing UI because it’s just so much damn fun to use. Let’s see what they do. 

<p id=""TagCloud"">
	 <a href=""/photos/tags/06/"" style=""font-size: 14px;"">06</a> 
	 <a href=""/photos/tags/africa/"" style=""font-size: 12px;"">africa</a> 
	 <a href=""/photos/tags/amsterdam/"" style=""font-size: 14px;"">amsterdam</a> 
	...
</p>

Again we have a simple collection of anchors like del.icio.us, only this time in a paragraph. But rather than using a class to represent the size of the tag they use an inline style. An inline style using a pixel-based font size. That’s so far away from the goal of separating style from content, they might as well use a <font> tag. You could theoretically parse that to extract the information, but you have more work to guess what the pixel sizes represent. Markup crime number two (and extra jail time for using non-breaking spaces purely for visual spacing purposes.)

Technorati 

Ah, now. Here, you’d expect something decent. After all, the Overlord of microformats and King of Semantics Tantek Çelik works there. Surely we’ll see something decent here? 

<ol class=""heatmap"">
	<li><em><em><em><em><a href=""/tag/Britney+Spears"">Britney Spears</a></em></em></em></em></li>
	<li><em><em><em><em><em><em><em><em><em><a href=""/tag/Bush"">Bush</a></em></em></em></em></em></em></em></em></em></li>
	<li><em><em><em><em><em><em><em><em><em><em><em><em><em><a href=""/tag/Christmas"">Christmas</a></em></em></em></em></em></em></em></em></em></em></em></em></em></li>
	...
	<li><em><em><em><em><em><em><a href=""/tag/SEO"">SEO</a></em></em></em></em></em></em></li>
	<li><em><em><em><em><em><em><em><em><em><em><em><em><em><em><em><a href=""/tag/Shopping"">Shopping</a></em></em></em></em></em></em></em></em></em></em></em></em></em></em></em></li>
	...
</ol>

Unfortunately it turns out not to be that decent, and stop calling me Shirley. It’s not exactly terrible code. It does recognise that a tag cloud is a list of links. And, since they’re in alphabetical order, that it’s an ordered list of links. That’s nice. However … fifteen nested <em> tags? FIFTEEN? That’s emphasis for you. Yes, it is parse-able, but it’s also something of a strange way of looking at emphasis. The HTML spec states that <em> is emphasis, and <strong> is for stronger emphasis. Nesting <em> tags seems counter to the idea that different tags are used for different levels of emphasis. Plus, if you had a screen reader that stressed the voice for emphasis, what would it do? Shout at you? Markup crime number three. 

So what should it be? 

As del.icio.us tells us, a tag cloud is a list of tags where the size that they are rendered at contains extra information. However, by hiding the extra context purely within the CSS or the HTML tags used, you are denying that context to some users. The basic assumption being made is that all users will be able to see the difference between font sizes, and this is demonstrably false. 

A better way to code a tag cloud is to put the context of the cloud within the content, not the markup or CSS alone. As an example, I’m going to take some of my favourite flickr tags and put them into a cloud which communicates the relative frequency of each tag. 

To start with a tag cloud in its most basic form is just a list of links. I am going to present them in alphabetical order, so I’ll use an ordered list. Into each list item I add the number of photos I have with that particular tag. The tag itself is linked to the page on flickr which contains those photos. So we end up with this first example. To display this as a traditional tag cloud, we need to alter it in a few ways: 


	The items need to be displayed next to each other, rather than one-per-line
	The context information should be hidden from display (but not from screen readers)
	The tag should link to the page of items with that tag


Displaying the items next to each other simply means setting the display of the list elements to inline. The context can be hidden by wrapping it in a <span> and then using the off-left method to hide it. And the link just means adding an anchor (with rel=""tag"" for some extra microformats bonus points). So, now we have a simple collection of links in our second example. 

The last stage is to add the sizes. Since we already have context in our content, the size is purely for visual rendering, so we can just use classes to define the different sizes. For my example, I’ll use a range of class names from not-popular through ultra-popular, in order of smallest to largest, and then use CSS to define different font sizes. If you preferred, you could always use less verbose class names such as  size1 through size6. Anyway, adding some classes and CSS gives us our final example, a semantic and more accessible tag cloud.",2006,Mark Norman Francis,marknormanfrancis,2006-12-09T00:00:00+00:00,https://24ways.org/2006/marking-up-a-tag-cloud/,code
129,Knockout Type - Thin Is Always In,"OS X has gorgeous native anti-aliasing (although I will admit to missing 10px aliased Geneva — *sigh*). This is especially true for dark text on a light background. However, things can go awry when you start using light text on a dark background. Strokes thicken. Counters constrict. Letterforms fill out like seasonal snackers.

 

So how do we combat the fat? In Safari and other Webkit-based browsers we can use the CSS ‘text-shadow’ property. While trying to add a touch more contrast to the navigation on haveamint.com I noticed an interesting side-effect on the weight of the type. 



The second line in the example image above has the following style applied to it:

  

This creates an invisible drop-shadow. (Why is it invisible? The shadow is positioned directly behind the type (the first two zeros) and has no spread (the third zero). So the color, black, is completely eclipsed by the type it is supposed to be shadowing.)

 

Why applying an invisible drop-shadow effectively lightens the weight of the type is unclear. What is clear is that our light-on-dark text is now of a comparable weight to its dark-on-light counterpart.

 

You can see this trick in effect all over ShaunInman.com and in the navigation on haveamint.com and Subtraction.com.

126,Intricate Fluid Layouts in Three Easy Steps,"The Year of the Script may have drawn attention away from CSS but building fluid, multi-column, cross-browser CSS layouts can still be as unpleasant as a lump of coal. Read on for a worry-free approach in three quick steps.

The layout system I developed, YUI Grids CSS, has three components. They can be used together as we’ll see, or independently.

The Three Easy Steps


	Choose fluid or fixed layout, and choose the width (in percents or pixels) of the page.
	Choose the size, orientation, and source-order of the main and secondary blocks of content.
	Choose the number of columns and how they distribute (for example 50%-50% or 25%-75%), using stackable and nestable grid structures.


The Setup

There are two prerequisites: We need to normalize the size of an em and opt into the browser rendering engine’s Strict Mode.

Ems are a superior unit of measure for our case because they represent the current font size and grow as the user increases their font size setting. This flexibility—the container growing with the user’s wishes—means larger text doesn’t get crammed into an unresponsive container. We’ll use YUI Fonts CSS to set the base size because it provides consistent-yet-adaptive font-sizes while preserving user control.

The second prerequisite is to opt into Strict Mode (more info on rendering modes) by declaring a Doctype complete with URI. You can choose XHTML or HTML, and Transitional or Strict. I prefer HTML 4.01 Strict, which looks like this:

<!DOCTYPE HTML PUBLIC ""-//W3C//DTD HTML 4.01//EN"" ""http://www.w3.org/TR/html4/strict.dtd"">

Including the CSS

A single small CSS file powers a nearly-infinite number of layouts thanks to a recursive system and the interplay between the three distinct components. You could prune to a particular layout’s specific needs, but why bother when the complete file weighs scarcely 1.8kb uncompressed? Compressed, YUI Fonts and YUI Grids combine for a miniscule 0.9kb over the wire.

You could save an HTTP request by concatenating the two CSS files, or by adding their contents to your own CSS, but I’ll keep them separate for now:

<link href=""fonts.css"" rel=""stylesheet"" type=""text/css"">
<link href=""grids.css"" rel=""stylesheet"" type=""text/css"">

Example: The Setup

Now we’re ready to build some layouts.

Step 1: Choose Fluid or Fixed Layout

Choose between preset widths of 750px, 950px, and 100% by giving a document-wrapping div an ID of doc, doc2, or doc3. These options cover most use cases, but it’s easy to define a custom fixed width.

The fluid 100% grid (doc3) is what I’ve been using almost exclusively since it was introduced in the last YUI released.

<body>
	<div id=""doc3""></div>
</body>

All pages are centered within the viewport, and grow with font size. The 100% width page (doc3) preserves 10px of breathing room via left and right margins. If you prefer your content flush to the viewport, just add doc3 {margin:auto} to your CSS.

Regardless of what you choose in the other two steps, you can always toggle between these widths and behaviors by simply swapping the ID value. It’s really that simple.

Example: 100% fluid layout

Step 2: Choose a Template Preset

This is perhaps the most frequently omitted step (they’re all optional), but I use it nearly every time. In a source-order-independent way (good for accessibility and SEO), “Template Presets” provide commonly used template widths compatible with ad-unit dimension standards defined by the Interactive Advertising Bureau, an industry association.

Choose between the six Template Presets (.yui-t1 through .yui-t6) by setting the class value on the document-wrapping div established in Step 1. Most frequently I use yui-t3, which puts the narrow secondary block on the left and makes it 300px wide. 

<body>
	<div id=""doc3"" class=""yui-t3""></div>
</body>

The Template Presets control two “blocks” of content, which are defined by two divs, each with yui-b (“b” for “block”) class values. Template Presets describe the width and orientation of the secondary block; the main block will take up the rest of the space.

<body>
	<div id=""doc3"" class=""yui-t3"">
	  <div class=""yui-b""></div>
	  <div class=""yui-b""></div>
	</div>
</body>

Use a wrapping div with an ID of yui-main to structurally indicate which block is the main block. This wrapper—not the source order—identifies the main block.

<body>
	<div id=""doc3"" class=""yui-t3"">
	  <div id=""yui-main"">
	    <div class=""yui-b""></div>
	  </div>
	  <div class=""yui-b""></div>
	</div>
</body>

Example: Main and secondary blocks sized and oriented with .yui-t3 Template Preset

Again, regardless of what values you choose in the other steps, you can always toggle between these Template Presets by toggling the class value of your document-wrapping div. It’s really that simple.

Step 3: Nest and Stack Grid Structures.

The bulk of the power of the system is in this third step. The key is that columns are built by parents telling children how to behave. By default, two children each consume half of their parent’s area. Put two units inside a grid structure, and they will sit side-by-side, and they will each take up half the space. Nest this structure and two columns become four. Stack them for rows of columns.

An Even Number of Columns

The default behavior creates two evenly-distributed columns. It’s easy. Define one parent grid with .yui-g (“g” for grid) and two child units with .yui-u (“u” for unit). The code looks like this:

<div class=""yui-g"">
	<div class=""yui-u first""></div>
	<div class=""yui-u""></div>
</div>

Be sure to indicate the “first“ unit because the :first-child pseudo-class selector isn’t supported across all A-grade browsers. It’s unfortunate we need to add this, but luckily it’s not out of place in the markup layer since it is structural information.

Example: Two evenly-distributed columns in the main content block

An Odd Number of Columns

The default system does not work for an odd number of columns without using the included “Special Grids” classes. To create three evenly distributed columns, use the “yui-gb“ Special Grid:

<div class=""yui-gb"">
	<div class=""yui-u first""></div>
	<div class=""yui-u""></div>
	<div class=""yui-u""></div>
</div>

Example: Three evenly distributed columns in the main content block

Uneven Column Distribution

Special Grids are also used for unevenly distributed column widths. For example, .yui-ge tells the first unit (column) to take up 75% of the parent’s space and the other unit to take just 25%.

<div class=""yui-ge"">
	<div class=""yui-u first""></div>
	<div class=""yui-u""></div>
</div>

Example: Two columns in the main content block split 75%-25%

Putting It All Together

Start with a full-width fluid page (div#doc3). Make the secondary block 180px wide on the right (div.yui-t4). Create three rows of columns: Three evenly distributed columns in the first row (div.yui-gb), two uneven columns (66%-33%) in the second row (div.yui-gc), and two evenly distributed columns in the thrid row.

<body>
	<!-- choose fluid page and Template Preset -->
	<div id=""doc3"" class=""yui-t4"">
		<!-- main content block -->
		<div id=""yui-main"">
			<div class=""yui-b"">
				<!-- stacked grid structure, Special Grid ""b"" -->
				<div class=""yui-gb"">
					<div class=""yui-u first""></div>
					<div class=""yui-u""></div>
					<div class=""yui-u""></div>
				</div>
				<!-- stacked grid structure, Special Grid ""c"" -->
				<div class=""yui-gc"">
					<div class=""yui-u first""></div>
					<div class=""yui-u""></div>
				</div>
				<!-- stacked grid structure -->
				<div class=""yui-g"">
					<div class=""yui-u first""></div>
					<div class=""yui-u""></div>
				</div>
			</div>
		</div>
		<!-- secondary content block -->
		<div class=""yui-b""></div>
	</div>
</body>

121,Hide And Seek in The Head,"If you want your JavaScript-enhanced pages to remain accessible and understandable to scripted and noscript users alike, you have to think before you code. Which functionalities are required (ie. should work without JavaScript)? Which ones are merely nice-to-have (ie. can be scripted)? You should only start creating the site when you’ve taken these decisions.

Special HTML elements

Once you have a clear idea of what will work with and without JavaScript, you’ll likely find that you need a few HTML elements for the noscript version only.

Take this example: A form has a nifty bit of Ajax that automatically and silently sends a request once the user enters something in a form field. However, in order to preserve accessibility, the user should also be able to submit the form normally. So the form should have a submit button in noscript browsers, but not when the browser supports sufficient JavaScript.

Since the button is meant for noscript browsers, it must be hard-coded in the HTML:

<input type=""submit"" value=""Submit form"" id=""noScriptButton"" />

When JavaScript is supported, it should be removed:

var checkJS = [check JavaScript support];
window.onload = function () {
	if (!checkJS) return;
	document.getElementById('noScriptButton').style.display = 'none';
}

Problem: the load event

Although this will likely work fine in your testing environment, it’s not completely correct. What if a user with a modern, JavaScript-capable browser visits your page, but has to wait for a huge graphic to load? The load event fires only after all assets, including images, have been loaded. So this user will first see a submit button, but then all of a sudden it’s removed. That’s potentially confusing.

Fortunately there’s a simple solution: play a bit of hide and seek in the <head>:

var checkJS = [check JavaScript support];
if (checkJS) {
	document.write('<style>#noScriptButton{display: none}</style>');
}

First, check if the browser supports enough JavaScript. If it does, document.write an extra <style> element that hides the button.

The difference with the previous technique is that the document.write command is outside any function, and is therefore executed while the JavaScript is being parsed. Thus, the #noScriptButton{display: none} rule is written into the document before the actual HTML is received.

That’s exactly what we want. If the rule is already present at the moment the HTML for the submit button is received and parsed, the button is hidden immediately. Even if the user (and the load event) have to wait for a huge image, the button is already hidden, and both scripted and noscript users see the interface they need, without any potentially confusing flashes of useless content.

In general, if you want to hide content that’s not relevant to scripted users, give the hide command in CSS, and make sure it’s given before the HTML element is loaded and parsed.

Alternative

Some people won’t like to use document.write. They could also add an empty <link /> element to the <head> and give it an href attribute once the browser’s JavaScript capabilities have been evaluated. The <link /> element is made to refer to a style sheet that contains the crucial #noScriptButton{display: none}, and everything works fine.

Important note: The script needs access to the <link />, and the only way to ensure that access is to include the empty <link /> element before your <script> tag.",2006,Peter-Paul Koch,ppk,2006-12-06T00:00:00+00:00,https://24ways.org/2006/hide-and-seek-in-the-head/,code
133,Gravity-Defying Page Corners,"While working on Stikkit, a “page curl” came to be.
Not being as crafty as Veerle, you see.
I fired up Photoshop to see what could be.
“Another copy is running on the network“ … oopsie.

With license issues sorted out and a concept in mind
I set out to create something flexible and refined.
One background image and code that is sure to be lean.
A simple solution for lazy people like me.

The curl I’ll be showing isn’t a curl at all.
It’s simply a gradient that’s 18 pixels tall.
With a fade to the left that’s diagonally aligned
and a small fade on the right that keeps the illusion defined.



Create a selection with the marquee tool (keeping in mind a reasonable minimum width) and drag a gradient (black to transparent) from top to bottom.



Now drag a gradient (the background color of the page to transparent) from the bottom left corner to the top right corner.



Finally, drag another gradient from the right edge towards the center, about 20 pixels or so.

But the top is flat and can be positioned precisely
just under the bottom right edge very nicely.
And there it will sit, never ever to be busted
by varying sizes of text when adjusted.

<div id=""page"">
	<div id=""page-contents"">
		<h2>Gravity-Defying!</h2>
		<p>Lorem ipsum dolor ...</p>
	</div>
</div>

Let’s dive into code and in the markup you’ll see
“is that an extra div?” … please don’t kill me?
The #page div sets the width and bottom padding
whose height is equal to the shadow we’re adding.



The #page-contents div will set padding in ems
to scale with the text size the user intends.
The background color will be added here too
but not overlapping the shadow where #page’s padding makes room.

A simple technique that you may find amusing
is to substitute a PNG for the GIF I was using.
For that would be crafty and future-proof, too.
The page curl could sit on any background hue.

Using Flickr photos outside of it is a bit of a problem though. There is a Flickr API, and you can get almost every page as an RSS feed, but in general it is a bit tricky to use Flickr photos inside your blog posts or web sites. You might not want to get into the whole API game or use a server side proxy script as you cannot retrieve RSS with Ajax because of the cross-domain security settings.

However, Flickr also provides an undocumented JSON  output, that can be used to hack your own solutions in JavaScript without having to use a server side script.


	If you enter the URL http://flickr.com/photos/tags/panda you get to the flickr page with photos tagged “panda”.
	If you enter the URL http://api.flickr.com/services/feeds/photos_public.gne?tags=panda&format=rss_200 you get the same page as an RSS feed.
	If you enter the URL http://api.flickr.com/services/feeds/photos_public.gne?tags=panda&format=json you get a JavaScript function called jsonFlickrFeed with a parameter that contains the same data in JSON format


You can use this to easily hack together your own output by just providing a function with the same name. I wanted to make it easier for you, which is why I created the helper getFlickr for you to download and use.

getFlickr for Non-Scripters

Simply include the javascript file getflickr.js and the style getflickr.css in the head of your document:

<script type=""text/javascript"" src=""getflickr.js""></script>
<link rel=""stylesheet"" href=""getflickr.css"" type=""text/css"">

Once this is done you can add links to Flickr pages anywhere in your document, and when you give them the CSS class getflickrphotos they get turned into gallery links. When a visitor clicks these links they turn into loading messages and show a “popup” gallery with the connected photos once they were loaded. As the JSON returned is very small it won’t take long. You can close the gallery, or click any of the thumbnails to view a photo. Clicking the photo makes it disappear and go back to the thumbnails.

Check out the example page and click the different gallery links to see the results.

Notice that getFlickr works with Unobtrusive JavaScript as when scripting is disabled the links still get to the photos on Flickr.

getFlickr for JavaScript Hackers

If you want to use getFlickr with your own JavaScripts you can use its main method leech():

getFlickr.leech(sTag, sCallback);

 
	sTag
	the tag you are looking for
	sCallback
	an optional function to call when the data was retrieved.
 

After you called the leech() method you have two strings to use:

 
	getFlickr.html[sTag]
	contains an HTML list (without the outer UL element) of all the images linked to the correct pages at flickr. The images are the medium size, you can easily change that by replacing _m.jpg with _s.jpg for thumbnails.
	getFlickr.tags[sTag]
	contains a string of all the other tags flickr users added with the tag you searched for(space separated)
 

You can call getFlickr.leech() several times when the page has loaded to cache several result feeds before the page gets loaded. This’ll make the photos quicker for the end user to show up. If you want to offer a form for people to search for flickr photos and display them immediately you can use the following HTML:

<form onsubmit=""getFlickr.leech(document.getElementById('tag').value, 'populate');return false"">
  <label for=""tag"">Enter Tag</label>
  <input type=""text"" id=""tag"" name=""tag"" />
  <input type=""submit"" value=""energize"" />
  <h3>Tags:</h3><div id=""tags""></div>
  <h3>Photos:</h3><ul id=""photos""></ul>
</form>

All the JavaScript you’ll need (for a basic display) is this:

function populate(){
  var tag = document.getElementById('tag').value;
  document.getElementById('photos').innerHTML = getFlickr.html[tag].replace(/_m\.jpg/g,'_s.jpg');
  document.getElementById('tags').innerHTML = getFlickr.tags[tag];
  return false;
}

Easy as pie, enjoy!

Check out the example page and try the form to see the results.",2006,Christian Heilmann,chrisheilmann,2006-12-03T00:00:00+00:00,https://24ways.org/2006/flickr-photos-on-demand/,code
130,Faster Development with CSS Constants,"Anyone even slightly familiar with a programming language will have come across the concept of constants – a fixed value that can be used through your code. For example, in a PHP script I might have a constant which is the email address that all emails generated by my application get sent to. 

$adminEmail = 'info@example.com';

I could then use $adminEmail in my script whenever I wanted an email to go to that address. The benefit of this is that when the client decides they want the email to go to a different address, I only need change it in one place – the place where I initially set the constant. I could also quite easily make this value user defined and enable the administrator to update the email address.

Unfortunately CSS doesn’t support constants. It would be really useful to be able to define certain values initially and then use them throughout a CSS file, so in this article I’m going to take a look at some of the methods we do have available and provide pointers to more in depth commentary on each. If you have a different method, or tip to share please add it to the comments.

So what options do we have?

One way to get round the lack of constants is to create some definitions at the top of your CSS file in comments, to define ‘constants’. A common use for this is to create a ‘color glossary’. This means that you have a quick reference to the colors used in the site to avoid using alternates by mistake and, if you need to change the colors, you have a quick list to go down and do a search and replace. 

In the below example, if I decide I want to change the mid grey to #999999, all I need to do is search and replace #666666 with #999999 – assuming I’ve remember to always use that value for things which are mid grey.

/*
Dark grey (text): #333333
Dark Blue (headings, links) #000066
Mid Blue (header) #333399
Light blue (top navigation) #CCCCFF
Mid grey: #666666
*/

This is a fairly low-tech method, but if used throughout the development of the CSS files can make changes far simpler and help to ensure consistency in your color scheme.

I’ve seen this method used by many designers however Garrett Dimon documents the method, with more ideas in the comments.

Going server-side

To truly achieve constants you will need to use something other than CSS to process the file before it is sent to the browser. You can use any scripting language – PHP, ASP, ColdFusion etc. to parse a CSS file in which you have entered constants. So that in a constants section of the CSS file you would have:

$darkgrey = '#333333';
$darkblue = '#000066';

The rest of the CSS file is as normal except that when you come to use the constant value you would use the constant name instead of adding the color:

p {
	color: $darkgrey;
}

Your server-side script could then parse the CSS file, replace the constant names with the constant values and serve a valid CSS file to the browser. Christian Heilmann has done just this for PHP however this could be adapted for any language you might have available on your server.

Shaun Inman came up with another way 
 of doing this that removes the need to link to a PHP script and also enables the adding of constants using the syntax of at-rules . This method is again using PHP and will require you to edit an .htaccess file. 

A further method is to generate static CSS files either using a script locally – if the constants are just to enable speed of development – or as part of the web application itself. Storing a template stylesheet with constant names in place of the values you will want to update means that your script can simply open the template, replace the variables and save the result as a new stylesheet file.

While CSS constants are a real help to developers, they can also be used to add new functionality to your applications. As with the email address example that I used at the beginning of this article, using a combination of CSS and server-side scripting you could enable a site administrator to select the colours for a new theme to be used on a page of a content managed site. By using constants you need only give them the option to change certain parts of the CSS and not upload a whole different CSS file, which could lead to some interesting results!

As we are unlikely to find real CSS constants under the tree this Christmas the above methods are some possibilities for better management of your stylesheets. However if you have better methods, CSS Constant horror stories or any other suggestions, add your comments below.",2006,Rachel Andrew,rachelandrew,2006-12-02T00:00:00+00:00,https://24ways.org/2006/faster-development-with-css-constants/,process
123,Fast and Simple Usability Testing,"Everyone knows by now that they should test the usability of their applications, but still hardly anybody actually does it. In this article I’ll share some tips I’ve picked up for doing usability tests quickly and effectively.

Relatively recent tools like Django and Ruby on Rails allow us to develop projects faster and to make significant changes later in the project timeline. Usability testing methods should now be adapted to fit this modern approach to development.

When to test

In an ideal world usability tests would be carried out frequently from an early stage of the project. Time and budget constraints lead this to be impractical; usability is often the first thing to get dropped from the project plan.

If you can only test at one stage in the project, whatever the size, the most valuable time is before your first public beta — leaving long enough to fix issues and not so late that you can’t rethink your scope.

There are three main categories of usability test:


	Testing design mockups
	Testing a new working application
	Testing established applications


Each category requires a slightly different approach. For small modern web projects you are most likely to be testing a new working application. You will of course have already done functional tests so you won’t be worried about the user breaking things. The main differences between the categories apply in how you word The Script.

Testing an established application is the most fun in my opinion. Humans are remarkably adaptable and rapidly develop coping strategies to work around usability issues in software they are forced to use. Uncovering these strategies may lead you to understand previously unspoken needs of your users. Often small changes to the application will have a dramatic affect on their everyday lives.

Who to test

When you have built a project to scratch your own itch, your intended audience will be people just like you. Test subjects in this case should be easy to find – friends, co-workers etc.

This is not always the case; your users may not be like you at all. When they are not, it’s all the more important to run usability tests. Testing on friends, family and co-workers is better than not doing usability tests at all, but it can’t be compared to testing on actual samples of your intended audience. People who would use the system will provide more genuine feedback and deeper insight.

Never let your test subjects put themselves in the shoes of your ‘actual’ users. For example, you should discourage comments like “Well, I would do this BUT if I was a bus driver I’d do that”. Users are not qualified to put themselves in the position of others. Inaccurate data is often worse than no data.

Aim for five or six test subjects: any more and you probably won’t learn anything new; any less and you’re likely to be overwhelmed by issues stemming from people’s individual personalities.

The Script

The Script is a single side of A4 (or letter) paper, consisting of questions for your testers and reminders for yourself. Have a balance of task-based questions and expectation analysis. This helps maintain consistency across tests. Expectation analysis is more important for testing designs and new applications: “Where would you find X?”, “What would you expect to happen if you clicked on Y?”. In an established system users will probably know where these things are though it can still be illuminating to ask these questions though phrased slightly differently.

Task-based questions involve providing a task for the user to complete. If you are testing an established system it is a good idea to ask users to bring in tasks that they would normally perform. This is because the user will be more invested in the outcome of the task and will behave in a more realistic fashion. When designing tasks for new systems and designs ensure you only provide loose task details for the same reason. Don’t tell testers to enter “Chantelle”; have them use their own name instead. Avoid introducing bias with the way questions are phrased.

It’s a good idea to ask for users’ first impressions at the beginning of the test, especially when testing design mockups. “What are the main elements on the page?” or “What strikes you first?”.

You script should run for a maximum of 45 minutes. 30-35 minutes is better; after this you are likely to lose their attention. Tests on established systems can take longer as there is more to learn from them. When scheduling the test you will need to leave yourself 5 minutes between each one to collate your notes and prepare for the next. Be sure to run through the script beforehand.

Your script should be flexible. It is possible that during the test a trend will come to light that opens up whole new avenues of possible questioning. For example, during one initial test of an established system I noticed that the test subject had been printing off items from the application and placing them in a folder in date order (the system ordered alphabetically). I changed the script to ask future participants in that run, if they ever used external tools to help them with tasks within the system. This revealed a number of interesting issues that otherwise would not have been found.

Running the tests

Treat your test subjects like hedgehogs. Depending on your target audience they probably feel a little nervous and perhaps even scared of you. So make them a little nest out of straw, stroke their prickles and give them some cat food. Alternatively, reassure them that you are testing the system and that they can’t give a wrong answer. Reward them with a doughnut or jam tart at the end. Try to ensure the test environment is relaxed and quiet, but also as close as possible to the situation where they would actually use the system.

Have your subjects talk out loud is very important as you can’t read their minds, but it is a very unnatural process. To loosen up your subjects and get them talking in the way you want them to, try the Stapler Trick. Give them a stapler or similar item and ask them to open it, take the staples out, replace them, shut the stapler and staple some paper – talking all the time about what they see, what they expect to happen, what actually happens and how that matches up. Make them laugh at you.

Say how long the test will take up front, and tell your subject why you are doing it. After the test has been completed, conclude by thanking them for their time and assuring them that they were very useful. Then give them the sugary treat.

What to look for

Primarily, you should look out for incidents where the user stops concentrating on her tasks and starts thinking about the tool and how she is going to use it. For example, when you are hammering in a nail you don’t think about how to use a hammer; good software should be the same. Words like ‘it’ and ‘the system’ and are good indications that the test subject has stopped thinking about the task in hand. Note questioning words, especially where testers question their own judgement, “why can’t I find …”, “I expected to see …” etc. as this indicates that the work flow for the task may have broken down.

Also keep an eye on occasions where the user completely fails to do a task. They may need some prompting to unstick them, but you should be careful not to bias the test. These should be the highest priority issues for you to fix. If users recover from getting stuck, make a note of how they recovered. Prolonged periods of silence from the test subject may also require prompting as they should be talking all the time. Ask them what they are thinking or looking for but avoid words like ‘try’ (e.g. ‘what are you trying to do?’) as this implies that they are currently failing.

Be wary of users’ opinions on aesthetics and be prepared to bring them back to the script if they get side-tracked.

Writing it up

Even if you are the only developer it’s important to summarise the key issues that emerged during testing: your notes won’t make much sense to you a week or so after the test.

If you are writing for other people, include a summary no longer than two pages; this can consist of a list or table of the issues including recommendations and their priorities. Remember to anonymise the users in the report. In team situations, you may be surprised at how many people are interested in the results of the usability test even if it doesn’t relate directly to something that they can fix.

To conclude…

Some usability testing is better than none at all, even for small projects or those with strict deadlines. Make the most of the time and resources available. Choose your users carefully, make them comfortable, summarise your report and don’t forget to leave a doughnut for yourself!",2006,Natalie Downe,nataliedowne,2006-12-16T00:00:00+00:00,https://24ways.org/2006/fast-and-simple-usability-testing/,process
122,"A Message To You, Rudy - CSS Production Notes","When more than one designer or developer work together on coding an XHTML/CSS template, there are several ways to make collaboration effective. Some prefer to comment their code, leaving a trail of bread-crumbs for their co-workers to follow. Others use accompanying files that contain their working notes or communicate via Basecamp.

For this year’s 24ways I wanted to share a technique that I has been effective at Stuff and Nonsense; one that unfortunately did not make it into the final draft of Transcending CSS. This technique, CSS production notes, places your page production notes in one convenient place within an XHTML document and uses nothing more than meaningful markup and CSS.

Let’s start with the basics; a conversation between a group of people. In the absence of notes or conversation elements in XHTML you need to make an XHTML compound that will effectively add meaning to the conversation between designers and developers. As each person speaks, you have two elements right there to describe what has been said and who has spoken: <blockquote> and its cite attribute. 

<blockquote cite=""andy""> 
	<p>This project will use XHTML1.0 Strict, CSS2.1 and all that malarkey.</p>
</blockquote>

With more than one person speaking, you need to establish a temporal order for the conversation. Once again, the element to do just that is already there in XHTML; the humble ordered list.

<ol id=""notes"">
	<li>
		<blockquote cite=""andy""> 
			<p>This project will use XHTML1.0 Strict, CSS2.1 and all that malarkey.</p>
		</blockquote> 
	</li>
	<li>
		<blockquote cite=""dan""> 
			<p>Those bits are simple and bulletproof.</p>
		</blockquote> 
	</li>
</ol>

Adding a new note is as simple as adding a new item to list, and if you prefer to add more information to each note, such as the date or time that the note was written, go right ahead. Place your note list at the bottom of the source order of your document, right before the closing <body> tag. One advantage of this approach over using conventional comments in your code is that all the notes are unobtrusive and are grouped together in one place, rather than being spread throughout your document.

Basic CSS styling

For the first stage you are going to add some basic styling to the notes area, starting with the ordered list. For this design I am basing the look and feel on an instant messenger window.



ol#notes {
	width : 300px; 
	height : 320px; 
	padding : .5em 0; 
	background : url(im.png) repeat; 
	border : 1px solid #333; 
	border-bottom-width : 2px; 
	-moz-border-radius : 6px; /* Will not validate */
	color : #000; 
	overflow : auto; 
}
ol#notes li { 
	margin : .5em; 
	padding : 10px 0 5px; 
	background-color : #fff; 
	border : 1px solid #666; 
	-moz-border-radius : 6px; /* Will not validate */ 
}
ol#notes blockquote { 
	margin : 0; 
	padding : 0; 
}
ol#notes p { 
	margin : 0 20px .75em;
	padding : 0; 
}
ol#notes p.date { 
	font-size : 92%;
	color : #666; 
	text-transform : uppercase; 
}

Take a gander at the first example.

You could stop right there, but without seeing who has left the note, there is little context. So next, extract the name of the commenter from the <blockquote>’s cite attribute and display it before each note by using generated content.

ol#notes blockquote:before { 
	content : "" ""attr(cite)"" said: ""; 
	margin-left : 20px; 
	font-weight : bold; 
}

Fun with more detailed styling

Now, with all of the information and basic styling in place, it’s time to have some fun with some more detailed styling to spruce up your notes. Let’s start by adding an icon for each person, once again based on their cite. First, all of the first paragraphs of a <blockquote>’s that includes a cite attribute are given common styles.

ol#notes blockquote[cite] p:first-child {
	min-height : 34px;
	padding-left : 40px; 
}

Followed by an individual background-image.

ol#notes blockquote[cite=""Andy""] p:first-child { 
	background : url(malarkey.png) no-repeat 5px 5px; 
} 

If you prefer a little more interactivity, add a :hover state to each <blockquote> and perhaps highlight the most recent comment.

ol#notes blockquote:hover { 
	background-color : #faf8eb; 
	border-top : 1px solid #fff; 
	border-bottom : 1px solid #333; 
}
ol#notes li:last-child blockquote { 
	background-color : #f1efe2; 
}



You could also adjust the style for each comment based on the department that the person works in, for example:

<li>
	<blockquote cite=""andy"" class=""designer""> 
		<p>This project will use XHTML1.0 Strict, CSS2.1 and all that malarkey.</p>
	</blockquote> 
</li>
<li>
	<blockquote cite=""dan""> 
		<p>Those bits are simple and bulletproof.</p>
	</blockquote> 
</li>
ol#notes blockquote.designer { border-color : #600; }

Take a look at the results of the second stage.

Show and hide the notes using CSS positioning

With your notes now dressed in their finest, it is time to tuck them away above the top of your working XHTML/CSS prototype so that you can reveal them when you need them, no JavaScript required. Start by moving the ordered list of notes off the top of the viewport leaving only a few pixels in view. It is also a good idea to make them semi-transparent by using the opacity property for browsers that have implemented it.

ol#notes { 
	position : absolute; 
	opacity : .25;
	z-index : 2000;  
	top : -305px; 
	left : 20px; 
}

Your last step is to add :hover and :focus dynamic pseudo-classes to reposition the list at the top of the viewport and restore full opacity to display them in their full glory when needed.

ol#notes:hover, ol#notes:focus {
	top : 0; 
	opacity : 1; 
}



Now it’s time to sit back, pour yourself a long drink and bask in the glory of the final result. Your notes are all stored in one handy place at the bottom of your document rather than being spread around your code. When your templates are complete, simply dive straight to the bottom and pull out the notes.

141,Compose to a Vertical Rhythm,"“Space in typography is like time in music. It is infinitely divisible, but a few proportional intervals can be much more useful than a limitless choice of arbitrary quantities.” So says the typographer Robert Bringhurst, and just as regular use of time provides rhythm in music, so regular use of space provides rhythm in typography, and without rhythm the listener, or the reader, becomes disorientated and lost.

On the Web, vertical rhythm – the spacing and arrangement of text as the reader descends the page – is contributed to by three factors: font size, line height and margin or padding. All of these factors must calculated with care in order that the rhythm is maintained. 

The basic unit of vertical space is line height. Establishing a suitable line height that can be applied to all text on the page, be it heading, body copy or sidenote, is the key to a solid dependable vertical rhythm, which will engage and guide the reader down the page. To see this in action, I’ve created an example with headings, footnotes and sidenotes. 

Establishing a suitable line height

The easiest place to begin determining a basic line height unit is with the font size of the body copy. For the example I’ve chosen 12px. To ensure readability the body text will almost certainly need some leading, that is to say spacing between the lines. A line-height of 1.5em would give 6px spacing between the lines of body copy. This will create a total line height of 18px, which becomes our basic unit. Here’s the CSS to get us to this point:

body {
	font-size: 75%; 
}
html>body {
	font-size: 12px; 
}
p {
	line-height 1.5em; 
}

There are many ways to size text in CSS and the above approach provides and accessible method of achieving the pixel-precision solid typography requires. By way of explanation, the first font-size reduces the body text from the 16px default (common to most browsers and OS set-ups) down to the 12px we require. This rule is primarily there for Internet Explorer 6 and below on Windows: the percentage value means that the text will scale predictably should a user bump the text size up or down. The second font-size sets the text size specifically and is ignored by IE6, but used by Firefox, Safari, IE7, Opera and other modern browsers which allow users to resize text sized in pixels.

Spacing between paragraphs

With our rhythmic unit set at 18px we need to ensure that it is maintained throughout the body copy. A common place to lose the rhythm is the gaps set between margins. The default treatment by web browsers of paragraphs is to insert a top- and bottom-margin of 1em. In our case this would give a spacing between the paragraphs of 12px and hence throw the text out of rhythm. If the rhythm of the page is to be maintained, the spacing of paragraphs should be related to the basic line height unit. This is achieved simply by setting top- and bottom-margins equal to the line height.

In order that typographic integrity is maintained when text is resized by the user we must use ems for all our vertical measurements, including line-height, padding and margins.

p {
	font-size:1em;
	margin-top: 1.5em;
	margin-bottom: 1.5em; 
}

Browsers set margins on all block-level elements (such as headings, lists and blockquotes) so a way of ensuring that typographic attention is paid to all such elements is to reset the margins at the beginning of your style sheet. You could use a rule such as:

body,div,dl,dt,dd,ul,ol,li,h1,h2,h3,h4,h5,h6,pre,form,fieldset,p,blockquote,th,td {  
	margin:0; 
	padding:0; 
}

Alternatively you could look into using the Yahoo! UI Reset style sheet which removes most default styling, so providing a solid foundation upon which you can explicitly declare your design intentions.

Variations in text size

When there is a change in text size, perhaps with a heading or sidenotes, the differing text should also take up a multiple of the basic leading. This means that, in our example, every diversion from the basic text size should take up multiples of 18px. This can be accomplished by adjusting the line-height and margin accordingly, as described following.

Headings

Subheadings in the example page are set to 14px. In order that the height of each line is 18px, the line-height should be set to 18 ÷ 14 = 1.286. Similarly the margins above and below the heading must be adjusted to fit. The temptation is to set heading margins to a simple 1em, but in order to maintain the rhythm, the top and bottom margins should be set at 1.286em so that the spacing is equal to the full 18px unit.

h2 {
	font-size:1.1667em;
	line-height: 1.286em;
	margin-top: 1.286em;
	margin-bottom: 1.286em; 
}

One can also set asymmetrical margins for headings, provided the margins combine to be multiples of the basic line height. In our example, a top margin of 1½ lines is combined with a bottom margin of half a line as follows:

h2 {
	font-size:1.1667em;
	line-height: 1.286em;
	margin-top: 1.929em;
	margin-bottom: 0.643em; 
}

Also in our example, the main heading is given a text size of 18px, therefore the line-height has been set to 1em, as has the margin:

h1 {
	font-size:1.5em;
	line-height: 1em;
	margin-top: 0;
	margin-bottom: 1em; 
}

Sidenotes

Sidenotes (and other supplementary material) are often set at a smaller size to the basic text. To keep the rhythm, this smaller text should still line up with body copy, so a calculation similar to that for headings is required. In our example, the sidenotes are set at 10px and so their line-height must be increased to 18 ÷ 10 = 1.8.

.sidenote {
	font-size:0.8333em;
	line-height:1.8em; 
}

Borders

One additional point where vertical rhythm is often lost is with the introduction of horizontal borders. These effectively act as shims pushing the subsequent text downwards, so a two pixel horizontal border will throw out the vertical rhythm by two pixels. A way around this is to specify horizontal lines using background images or, as in our example, specify the width of the border in ems and adjust the padding to take up the slack. 

The design of the footnote in our example requires a 1px horizontal border. The footnote contains 12px text, so 1px in ems is 1 ÷ 12 = 0.0833. I have added a margin of 1½ lines above the border (1.5 × 18 ÷ 12 = 2.5ems), so to maintain the rhythm the border + padding must equal a ½ (9px). We know the border is set to 1px, so the padding must be set to 8px. To specify this in ems we use the familiar calculation: 8 ÷ 12 = 0.667.

Hit me with your rhythm stick

Composing to a vertical rhythm helps engage and guide the reader down the page, but it takes typographic discipline to do so. It may seem like a lot of fiddly maths is involved (a few divisions and multiplications never hurt anyone) but good type setting is all about numbers, and it is this attention to detail which is the key to success.",2006,Richard Rutter,richardrutter,2006-12-12T00:00:00+00:00,https://24ways.org/2006/compose-to-a-vertical-rhythm/,design
137,Cheating Color,"Have you ever been strapped to use specific colors outlined in a branding guide? Felt restricted because those colors ended up being too light or dark for the way you want to use them?

Here’s the solution: throw out your brand guide.

gasp!

OK, don’t throw it out. Just put it in a drawer for a few minutes.

Branding Guides be Damned

When dealing with color on screen, it’s easy to get caught up in literal values from hex colors, you can cheat colors ever so slightly to achieve the right optical value. This is especially prevalent when trying to bring a company’s identity colors to a screen design. Because the most important idea behind a brand guide is to help a company maintain the visual integrity of their business, consider hex numbers to be guidelines rather than law. Once you are familiar enough with the colors your company uses, you can start to flex them a bit, and take a few liberties.

This is a quick method for cheating to get the color you really want. With a little sleight of design, we can swap a color that might be part of your identity guidelines, with one that works better optically, and no one will be the wiser!

Color is a Wily Beast

This might be hard: You might have to break out of the idea that a color can only be made using one method. Color is fluid. It interacts and changes based on its surroundings. Some colors can appear lighter or darker based on what color they appear on or next to. The RGB gamut is additive color, and as such, has a tendency to push contrast in the direction that objects may already be leaning—increasing the contrast of light colors on dark colors and decreasing the contrast of light on light. Obviously, because we are talking about monitors here, these aren’t hard and fast rules.

Cheat and Feel Good About It

On a light background, when you have a large element of a light color, a small element of the same color will appear lighter.

Enter our fake company: Double Dagger. They manufacture footnotes. Take a look at Fig. 1 below. The logo (Double Dagger), rule, and small text are all #6699CC. Because the logo so large, we get a good sense of the light blue color. Unfortunately, the rule and small text beneath it feel much lighter because we can’t create enough contrast with such small shapes in that color.

Now take a look at Fig. 2. Our logo is still #6699CC, but now the rule and smaller text have been cheated to #4477BB, effectively giving us the same optical color that we used in the logo. You will find that we get a better sense of the light blue, and the added benefit of more contrast for our text. Doesn’t that feel good?



Conversely, when you have a large element of a dark color, a small element of the same color will appear darker.

Let’s look at Fig. 3 below. Double Dagger has decided to change its identity colors from blue to red. In Fig. 3, our logo, rule, and small text are all #330000, a very dark red. If you look at the rule and small text below the logo, you will notice that they seem dark enough to be confused with black. The dark red can’t be sustained by the smaller shapes. Now let’s look at Fig. 4. The logo is still #33000, but we’ve now cheated the rule and smaller text to #550000. This gives us a better sense of a red, but preserves the dark and moody direction the company has taken.



But we’ve only touched on color against a white background. For colors against a darker background, you may find lighter colors work fine, but darker colors need to be cheated a bit to the lighter side in order to reach a good optical equivalent. Take a look below at Fig. 5 and Fig. 6. Both use the same exact corresponding colors as Fig. 1 and Fig. 2 above, but now they are set against a dark background. Where the blue used in Fig. 1 above was too light for the smaller elements, we find it is just right for them in Fig. 5, and the darker blue we used in Fig. 2 has now proven too dark for a dark background, as evidenced in Fig. 6.



Your mileage may vary, and this may not be applicable in all situations, but consider it to be just another tool on your utility belt for dealing with color problems.",2006,Jason Santa Maria,jasonsantamaria,2006-12-23T00:00:00+00:00,https://24ways.org/2006/cheating-color/,design
128,Boost Your Hyperlink Power,"There are HTML elements and attributes that we use every day. Headings, paragraphs, lists and images are the mainstay of every Web developer’s toolbox. Perhaps the most common tool of all is the anchor. The humble a element is what joins documents together to create the gloriously chaotic collection we call the World Wide Web.

Anatomy of an Anchor

The power of the anchor element lies in the href attribute, short for hypertext reference. This creates a one-way link to another resource, usually another page on the Web:

<a href=""http://allinthehead.com/"">

The href attribute sits in the opening a tag and some descriptive text sits between the opening and closing tags:

<a href=""http://allinthehead.com/"">Drew McLellan</a>

“Whoop-dee-freakin’-doo,” I hear you say, “this is pretty basic stuff” – and you’re quite right. But there’s more to the anchor element than just the href attribute.

The Theory of relativity

You might be familiar with the rel attribute from the link element. I bet you’ve got something like this in the head of your documents:

<link rel=""stylesheet"" type=""text/css"" media=""screen"" href=""styles.css"" />

The rel attribute describes the relationship  between the linked document and the current document. In this case, the value of rel is “stylesheet”. This means that the linked document is the stylesheet for the current document: that’s its relationship.

Here’s another common use of rel:

<link rel=""alternate"" type=""application/rss+xml"" title=""my RSS feed"" href=""index.xml"" />

This describes the relationship of the linked file – an RSS feed – as “alternate”: an alternate view of the current document.

Both of those examples use the link element but you are free to use the rel attribute in regular hyperlinks. Suppose you’re linking to your RSS feed in the body of your page:

Subscribe to <a href=""index.xml"">my RSS feed</a>.

You can add extra information to this anchor using the rel attribute:

Subscribe to <a href=""index.xml"" rel=""alternate"" type=""application/rss+xml"">my RSS feed</a>.

There’s no prescribed list of values for the rel attribute so you can use whatever you decide is semantically meaningful. Let’s say you’ve got a complex e-commerce application that includes a link to a help file. You can explicitly declare the relationship of the linked file as being “help”:

<a href=""help.html"" rel=""help"">need help?</a>

Elemental Microformats

Although it’s completely up to you what values you use for the rel attribute, some consensus is emerging in the form of microformats. Some of the simplest microformats make good use of rel. For example, if you are linking to a license that covers the current document, use the rel-license microformat:

Licensed under a <a href=""http://creativecommons.org/licenses/by/2.0/"" rel=""license"">Creative Commons attribution license</a>

That describes the relationship of the linked document as “license.”

The rel-tag microformat goes a little further. It uses rel to describe the final part of the URL of the linked file as a “tag” for the current document:

Learn more about <a href=""http://en.wikipedia.org/wiki/Microformats"" rel=""tag"">semantic markup</a>

This states that the current document is being tagged with the value “Microformats.”

XFN, which stands for XHTML Friends Network, is a way of describing relationships between people:

<a href=""http://allinthehead.com/"" rel=""friend"">Drew McLellan</a>

This microformat makes use of a very powerful property of the rel attribute. Like the class attribute, rel can take multiple values, separated by spaces:

<a href=""http://allinthehead.com/"" rel=""friend met colleague"">Drew McLellan</a>

Here I’m describing Drew as being a friend, someone I’ve met, and a colleague (because we’re both Web monkies).

You Say You Want a revolution

While rel describes the relationship of the linked resource to the current document, the rev attribute describes the reverse relationship: it describes the relationship of the current document to the linked resource. Here’s an example of a link that might appear on help.html:

<a href=""shoppingcart.html"" rev=""help"">continue shopping</a>

The rev attribute declares that the current document is “help” for the linked file.

The vote-links microformat makes use of the rev attribute to allow you to qualify your links. By using the value “vote-for” you can describe your document as being an endorsement of the linked resource:

I agree with <a href=""http://richarddawkins.net/home"" rev=""vote-for"">Richard Dawkins</a>.

There’s a corresponding vote-against value. This means that you can link to a document but explicitly state that you don’t agree with it.

I agree with <a href=""http://richarddawkins.net/home"" rev=""vote-for"">Richard Dawkins</a>
about those <a href=""http://www.icr.org/"" rev=""vote-against"">creationists</a>. 

Of course there’s nothing to stop you using both rel and rev on the same hyperlink:

<a href=""http://richarddawkins.net/home"" rev=""vote-for"" rel=""muse"">Richard Dawkins</a>

The Wisdom of Crowds

The simplicity of rel and rev belies their power. They allow you to easily add extra semantic richness to your hyperlinks. This creates a bounty that can be harvested by search engines, aggregators and browsers. Make it your New Year’s resolution to make friends with these attributes and extend the power of hypertext.",2006,Jeremy Keith,jeremykeith,2006-12-18T00:00:00+00:00,https://24ways.org/2006/boost-your-hyperlink-power/,code
136,Making XML Beautiful Again: Introducing Client-Side XSL,"Remember that first time you saw XML and got it? When you really understood what was possible and the deep meaning each element could carry? Now when you see XML, it looks ugly, especially when you navigate to a page of XML in a browser. Well, with every modern browser now supporting XSL 1.0, I’m going to show you how you can turn something as simple as an ATOM feed into a customised page using a browser, Notepad and some XSL.

What on earth is this XSL?

XSL is a family of recommendations for defining XML document transformation and presentation. It consists of three parts:


	XSLT 1.0 – Extensible Stylesheet Language Transformation, a language for transforming XML
	XPath 1.0 – XML Path Language, an expression language used by XSLT to access or refer to parts of an XML document. (XPath is also used by the XML Linking specification)
	XSL-FO 1.0 – Extensible Stylesheet Language Formatting Objects, an XML vocabulary for specifying formatting semantics


XSL transformations are usually a one-to-one transformation, but with newer versions (XSL 1.1 and XSL 2.0) its possible to create many-to-many transformations too. So now you have an overview of XSL, on with the show…

So what do I need?

So to get going you need a browser an supports client-side XSL transformations such as Firefox, Safari, Opera or Internet Explorer. Second, you need a source XML file – for this we’re going to use an ATOM feed from Flickr.com. And lastly, you need an editor of some kind. I find Notepad++ quick for short XSLs, while I tend to use XMLSpy or Oxygen for complex XSL work. 

Because we’re doing a client-side transformation, we need to modify the XML file to tell it where to find our yet-to-be-written XSL file. Take a look at the source XML file, which originates from my Flickr photos tagged sky, in ATOM format.

The top of the ATOM file now has an additional <?xml-stylesheet /> instruction, as can been seen on Line 2 below. This instructs the browser to use the XSL file to transform the document.

<?xml version=""1.0"" encoding=""utf-8"" standalone=""yes""?>
<?xml-stylesheet type=""text/xsl"" href=""flickr_transform.xsl""?>
<feed xmlns=""http://www.w3.org/2005/Atom""
	xmlns:dc=""http://purl.org/dc/elements/1.1/"">

Your first transformation

Your first XSL will look something like this:

<?xml version=""1.0"" encoding=""utf-8""?>
<xsl:stylesheet version=""1.0""
	xmlns:xsl=""http://www.w3.org/1999/XSL/Transform""
	xmlns:atom=""http://www.w3.org/2005/Atom""
	xmlns:dc=""http://purl.org/dc/elements/1.1/"">
	<xsl:output method=""html"" encoding=""utf-8""/>
</xsl:stylesheet>

This is pretty much the starting point for most XSL files. You will notice the standard XML processing instruction at the top of the file (line 1). We then switch into XSL mode using the XSL namespace on all XSL elements (line 2). In this case, we have added namespaces for ATOM (line 4) and Dublin Core (line 5). This means the XSL can now read and understand those elements from the source XML. 

After we define all the namespaces, we then move onto the xsl:output element (line 6). This enables you to define the final method of output. Here we’re specifying html, but you could equally use XML or Text, for example. The encoding attributes on each element do what they say on the tin. As with all XML, of course, we close every element including the root.

The next stage is to add a template, in this case an <xsl:template /> as can be seen below:

<?xml version=""1.0"" encoding=""utf-8""?>
<xsl:stylesheet version=""1.0""
	xmlns:xsl=""http://www.w3.org/1999/XSL/Transform""
	xmlns:atom=""http://www.w3.org/2005/Atom""
	xmlns:dc=""http://purl.org/dc/elements/1.1/"">
	<xsl:output method=""html"" encoding=""utf-8""/>
	<xsl:template match=""/"">
		<html>
			<head>
				<title>Making XML beautiful again : Transforming ATOM</title>
			</head>
			<body>
				<xsl:apply-templates select=""/atom:feed""/>
			</body>
		</html>
	</xsl:template>
</xsl:stylesheet>

The beautiful thing about XSL is its English syntax, if you say it out loud it tends to make sense. 

The / value for the match attribute on line 8 is our first example of XPath syntax. The expression / matches any element – so this <xsl:template/> will match against any element in the document. As the first element in any XML document is the root element, this will be the one matched and processed first.

Once we get past our standard start of a HTML document, the only instruction remaining in this <xsl:template/> is to look for and match all <atom:feed/> elements using the <xsl:apply-templates/> in line 14, above.

<?xml version=""1.0"" encoding=""utf-8""?>
<xsl:stylesheet version=""1.0""
	xmlns:xsl=""http://www.w3.org/1999/XSL/Transform""
	xmlns:atom=""http://www.w3.org/2005/Atom""
	xmlns:dc=""http://purl.org/dc/elements/1.1/"">
	<xsl:output method=""html"" encoding=""utf-8""/>
	<xsl:template match=""/"">
		<xsl:apply-templates select=""/atom:feed""/>
	</xsl:template>
	<xsl:template match=""/atom:feed"">
		<div id=""content"">
			<h1>
				<xsl:value-of select=""atom:title""/>
			</h1>
			<p>
				<xsl:value-of select=""atom:subtitle""/>
			</p>
			<ul id=""entries"">
				<xsl:apply-templates select=""atom:entry""/>
			</ul>
		</div>
	</xsl:template>
</xsl:stylesheet>

This new template (line 12, above) matches <feed/> and starts to write the new HTML elements out to the output stream. The <xsl:value-of/> does exactly what you’d expect – it finds the value of the item specifed in its select attribute. With XPath you can select any element or attribute from the source XML. 

The last part is a repeat of the now familiar <xsl:apply-templates/> from before, but this time we’re using it inside of a called template. Yep, XSL is full of recursion…

<xsl:template match=""atom:entry"">
	<li class=""entry"">
		<h2>
			<a href=""{atom:link/@href}"">
				<xsl:value-of select=""atom:title""/>
			</a>
		</h2>
		<p class=""date"">
			(<xsl:value-of select=""substring-before(atom:updated,'T')""/>)
		</p>
		<p class=""content"">
			<xsl:value-of select=""atom:content"" disable-output-escaping=""yes""/>
		</p>
		<xsl:apply-templates select=""atom:category""/>
	</li>
</xsl:template>

The <xsl:template/> which matches atom:entry (line 1) occurs every time there is a <entry/> element in the source XML file. So in total that is 20 times, this is naturally why XSLT is full of recursion. This <xsl:template/> has been matched and therefore called higher up in the document, so we can start writing list elements directly to the output stream. The first part is simply a <h2/> with a link wrapped within it (lines 3-7). We can select attributes using XPath using @. 

The second part of this template selects the date, but performs a XPath string function on it. This means that we only get the date and not the time from the string (line 9). This is achieved by getting only the part of the string that exists before the T. 

Regular Expressions are not part of the XPath 1.0 string functions, although XPath 2.0 does include them. Because of this, in XSL we tend to rely heavily on the available XML output. 

The third part of the template (line 12) is a <xsl:value-of/> again, but this time we use an attribute of <xsl:value-of/> called disable output escaping to turn escaped characters back into XML. 

The very last section is another <xsl:apply-template/> call, taking us three templates deep. Do not worry, it is not uncommon to write XSL which go 20 or more templates deep!

<xsl:template match=""atom:category"">
	<xsl:for-each select=""."">
		<xsl:element name=""a"">
			<xsl:attribute name=""rel"">
				<xsl:text>tag</xsl:text>
			</xsl:attribute>
			<xsl:attribute name=""href"">
				<xsl:value-of select=""concat(@scheme, @term)""/>
			</xsl:attribute>
			<xsl:value-of select=""@term""/>
		</xsl:element>
		<xsl:text> </xsl:text>
	</xsl:for-each>
</xsl:template>

In our final <xsl:template/>, we see a combination of what we have done before with a couple of twists. Once we match atom:category we then count how many elements there are at that same level (line 2). The XPath . means ‘self’, so we count how many category elements are within the <entry/> element. 

Following that, we start to output a link with a rel attribute of the predefined text, tag (lines 4-6). In XSL you can just type text, but results can end up with strange whitespace if you do (although there are ways to simply remove all whitespace). 

The only new XPath function in this example is concat(), which simply combines what XPaths or text there might be in the brackets. We end the output for this tag with an actual tag name (line 10) and we add a space afterwards (line 12) so it won’t touch the next tag. (There are better ways to do this in XSL using the last() XPath function). 

After that, we go back to the <xsl:for-each/> element again if there is another category element, otherwise we end the <xsl:for-each/> loop and end this <xsl:template/>.

A touch of style

Because we’re using recursion through our templates, you will find this is the end of the templates and the rest of the XML will be ignored by the parser. Finally, we can add our CSS to finish up. (I have created one for Flickr and another for News feeds)

<style type=""text/css"" media=""screen"">@import ""flickr_overview.css?v=001"";</style>

So we end up with a nice simple to understand but also quick to write XSL which can be used on ATOM Flickr feeds and ATOM News feeds. With a little playing around with XSL, you can make XML beautiful again.

125,Accessible Dynamic Links,"Although hyperlinks are the soul of the World Wide Web, it’s worth using them in moderation. Too many links becomes a barrier for visitors navigating their way through a page. This difficulty is multiplied when the visitor is using assistive technology, or is using a keyboard; being able to skip over a block of links doesn’t make the task of finding a specific link any easier.

In an effort to make sites easier to use, various user interfaces based on the hiding and showing of links have been crafted. From drop-down menus to expose the deeper structure of a website, to a decluttering of skip links so as not to impact design considerations. Both are well intentioned with the aim of preserving a good usability experience for the majority of a website’s audience; hiding the real complexity of a page until the visitor interacts with the element.

When JavaScript is not available

The modern dynamic link techniques rely on JavaScript and CSS, but regardless of whether scripting and styles are enabled or not, we should consider the accessibility implications, particularly for screen-reader users, and people who rely on keyboard access.

In typical web standards-based drop-down navigation implementations, the rough consensus is that the navigation should be structured as nested lists so when JavaScript is not available the entire navigation map is available to the visitor. This creates a situation where a visitor is faced with potentially well over 50 links on every page of the website. Keyboard access to such structures is frustrating, there’s far too many options, and the method of serially tabbing through each link looking for a specific one is tedious.

Instead of offering the visitor an indigestible chunk of links when JavaScript is not available, consider instead having the minimum number of links on a page, and when JavaScript is available bringing in the extra links dynamically. Santa Chris Heilmann offers an excellent proof of concept in making Ajax navigation optional.

When JavaScript is enabled, we need to decide how to hide links. One technique offers a means of comprehensively hiding links from keyboard users and assistive technology users. Another technique allows keyboard and screen-reader users to access links while they are hidden, and making them visible when reached.

Hiding the links

In JavaScript enhanced pages whether a link displays on screen depends on a certain event happening first. For example, a visitor needs to click a top-level navigation link that makes a set of sub-navigation links appear. In these cases, we need to ensure that these links are not available to any user until that event has happened.

The typical way of hiding links is to style the anchor elements, or its parent nodes with display: none. This has the advantage of taking the links out of the tab order, so they are not focusable. It’s useful in reducing the number of links presented to a screen-reader or keyboard user to a minimum. Although the links are still in the document (they can be referenced and manipulated using DOM Scripting), they are not directly triggerable by a visitor.

Once the necessary event has happened, like our visitor has clicked on a top-level navigation link which shows our hidden set of links, then we can display the links to the visitor and make them triggerable. This is done simply by undoing the display: none, perhaps by setting the display back to block for block level elements, or inline for inline elements. For as long as this display style remains, the links are in the tab order, focusable by keyboard, and triggerable.

A common mistake in this situation is to use visibility: hidden, text-indent: -999em, or position: absolute with left: -999em to position these links off-screen. But all of these links remain accessible via keyboard tabbing even though the links remain hidden from screen view. In some ways this is a good idea, but for hiding sub-navigation links, it presents the screen-reader user and keyboard user with too many links to be of practical use.

Moving the links out of sight

If you want a set of text links accessible to screen-readers and keyboard users, but don’t want them cluttering up space on the screen, then style the links with position: absolute; left: -999em. Links styled this way remain in the tab order, and are accessible via keyboard. (The position: absolute is added as a style to the link, not to a parent node of the link – this will give us a useful hook to solve the next problem).

a.helper {
	position: absolute;
	left: -999em;
}

One important requirement when displaying links off-screen is that they are visible to a keyboard user when they receive focus. Tabbing on a link that is not visible is a usability mudpit, since the visitor has no visible cue as to what a focused link will do, or where it will go.

The simple answer is to restyle the link so that it appears on the screen when the hidden link receives focus. The anchor’s :focus pseudo-class is a logical hook to use, and with the following style repositions the link onscreen when it receives the focus:

a.helper:focus, a.helper.focus {
	top: 0;
	left: 0;
}

This technique is useful for hiding skip links, and options you want screen-reader and keyboard users to use, but don’t want cluttering up the page. Unfortunately Internet Explorer 6 and 7 don’t support the focus pseudo-class, which is why there’s a second CSS selector a.helper.focus so we can use some JavaScript to help out. When the page loads, we look for all links that have a class of helper and add in onfocus and onblur event handlers:

if (anchor.className == ""helper"") {
	anchor.onfocus = function() {
		this.className = 'helper focus';
	}
	anchor.onblur = function() {
		this.className = 'helper';
	}
}

Since we are using JavaScript to cover up for deficiencies in Internet Explorer, it makes sense to use JavaScript initially to place the links off-screen. That way an Internet Explorer user with JavaScript disabled can still use the skip link functionality.

It is vital that the number of links rendered in this way is kept to a minimum. Every link you offer needs to be tabbed through, and gets read out in a screen reader. Offer these off-screen links that directly benefit these types of visitor.

Andy Clarke and Kimberly Blessing use a similar technique in the Web Standards Project‘s latest design, but their technique involves hiding the skip link in plain sight and making it visible when it receives focus. Navigate the page using just the tab key to see the accessibility-related links appear when they receive focus.

This technique is also a good way of hiding image replaced text. That way the screen-readers still get the actual text, and the website still gets its designed look.

Which way?

If the links are not meant to be reachable until a certain event has occurred, then the display: none technique is the preferred approach. If you want the links accessible but out of the way until they receive focus, then the off-screen positioning (or Andy’s hiding in plain sight technique) is the way to go.",2006,Mike Davies,mikedavies,2006-12-05T00:00:00+00:00,https://24ways.org/2006/accessible-dynamic-links/,ux
135,A Scripting Carol,"We all know the stories of the Ghost of Scripting Past – a time when the web was young and littered with nefarious scripting, designed to bestow ultimate control upon the developer, to pollute markup with event handler after event handler, and to entrench advertising in the minds of all that gazed upon her.

And so it came to be that JavaScript became a dirty word, thrown out of solutions by many a Scrooge without regard to the enhancements that JavaScript could bring to any web page. JavaScript, as it was, was dead as a door-nail.

With the arrival of our core philosophy that all standardistas hold to be true: “separate your concerns – content, presentation and behaviour,” we are in a new era of responsible development the Web Standards Way™. Or are we? Have we learned from the Ghosts of Scripting Past? Or are we now faced with new problems that come with new ways of implementing our solutions?

The Ghost of Scripting Past

If the Ghost of Scripting Past were with us it would probably say: 


	You must remember your roots and where you came from, and realize the misguided nature of your early attempts for control. That person you see down there, is real and they are the reason you exist in the first place… without them, you are nothing.


In many ways we’ve moved beyond the era of control and we do take into account the user, or at least much more so than we used to. Sadly – there is one advantage that old school inline event handlers had where we assigned and reassigned CSS style property values on the fly – we knew that if JavaScript wasn’t supported, the styles wouldn’t be added because we ended up doing them at the same time.

If anything, we need to have learned from the past that just because it works for us doesn’t mean it is going to work for anyone else – we need to test more scenarios than ever to observe the multitude of browsing arrangements we’ll observe: CSS on with JavaScript off, CSS off/overridden with JavaScript on, both on, both off/not supported. It is a situation that is ripe for conflict.

This may shock some of you, but there was a time when testing was actually easier: back in the day when Netscape 4 was king. Yes, that’s right. I actually kind of enjoyed Netscape 4 (hear me out, please). With NS4’s CSS implementation known as JavaScript Style Sheets, you knew that if JavaScript was off the styles were off too.

The Ghost of Scripting Present

With current best practice – we keep our CSS and JavaScript separate from each other. So what happens when some of our fancy, unobtrusive DOM Scripting doesn’t play nicely with our wonderfully defined style rules?

Lets look at one example of a collapsing and expanding menu to illustrate where we are now:

Simple Collapsing/Expanding Menu Example

We’re using some simple JavaScript (I’m using jquery in this case) to toggle between a CSS state for expanded and not expanded:

JavaScript

$(document).ready(function(){
	TWOFOURWAYS.enableTree();
});
var TWOFOURWAYS = new Object();
TWOFOURWAYS.enableTree = function ()
{
	$(""ul li a"").toggle(function(){
		$(this.parentNode).addClass(""expanded"");
	}, function() {
		$(this.parentNode).removeClass(""expanded"");
	});
	return false;	
}

CSS

ul li ul {
	display: none;
}
ul li.expanded ul {
	display: block;
}

At this point we’ve separated our presentation from our content and behaviour, and all is well, right?

Not quite.

Here’s where I typically see failures in the assessment work that I do on web sites and applications (Yes, call me Scrooge – I don’t care!). We know our page needs to work with or without scripting, and we know it needs to work with or without CSS. All too often the testing scenarios don’t take into account combinations.

Testing it out

So what happens when we test this? Make sure you test with:


	CSS off
	JavaScript off


Use the simple example again.

With CSS off, we revert to a simple nested list of links and all functionality is maintained. With JavaScript off, however, we run into a problem – we have now removed the ability to expand the menu using the JavaScript triggered CSS change.

Hopefully you see the problem – we have a JavaScript and CSS dependency that is critical to the functionality of the page. Unobtrusive scripting and binary on/off tests aren’t enough. We need more.

This Ghost of Scripting Present sighting is seen all too often.

Lets examine the JavaScript off scenario a bit further – if we require JavaScript to expand/show the branch of the tree we should use JavaScript to hide them in the first place. That way we guarantee functionality in all scenarios, and have achieved our baseline level of interoperability. 

To revise this then, we’ll start with the sub items expanded, use JavaScript to collapse them, and then use the same JavaScript to expand them.

HTML

<ul>
	<li><a href=""#"">Main Item</a>

This isn’t rocket surgery by any means. It is a simple solution to a ghostly problem that is too easily overlooked (and often is).

The Ghost of Scripting Future

Well, I’m not so sure about this one, but I’m guessing that in a few years’ time, we’ll all have seen a few more apparitions and have a few more tales to tell. And hopefully we’ll be able to share them on 24 ways.

325,"""Z's not dead baby, Z's not dead""","While Mr. Moll and Mr. Budd have pipped me to the post with their predictions for 2006, I’m sure they won’t mind if I sneak in another. The use of positioning together with z-index will be one of next year’s hot techniques 

Both has been a little out of favour recently. For many, positioned layouts made way for the flexibility of floats. Developers I speak to often associate z-index with Dreamweaver’s layers feature. But in combination with alpha transparency support for PNG images in IE7 and full implementation of position property values, the stacking of elements with z-index is going to be big. I’m going to cover the basics of z-index and how it can be used to create designs which ‘break out of the box’.

No positioning? No Z!

Remember geometry? The x axis represents the horizontal, the y axis represents the vertical. The z axis, which is where we get the z-index, represents /depth/. Elements which are stacked using z-index are stacked from front to back and z-index is only applied to elements which have their position property set to relative or absolute. No positioning, no z-index. Z-index values can be either negative or positive and it is the element with the highest z-index value appears closest to the viewer, regardless of its order in the source. Furthermore, if more than one element are given the same z-index, the element which comes last in source order comes out top of the pile. 

Let’s take three <div>s.

<div id=""one""></div>
 <div id=""two""></div>
 <div id=""three""></div>

 #one { 
     position: relative; 
     z-index: 3;
 }

 #two { 
     position: relative; 
     z-index: 1;
 }

 #three {
     position: relative; 
     z-index: 2;
 }



As you can see, the <div> with the z-index of 3 will appear closest, even though it comes before its siblings in the source order. As these three <div>s have no defined positioning context in the form of a positioned parent such as a <div>, their stacking order is defined from the root element <html>. Simple stuff, but these building blocks are the basis on which we can create interesting interfaces (particularly when used in combination with image replacement and transparent PNGs).

Brand building

Now let’s take three more basic elements, an <h1>, <blockquote> and <p>, all inside a branding <div> which acts a new positioning context. By enclosing them inside a positioned parent, we establish a new stacking order which is independent of either the root element or other positioning contexts on the page.

<div id=""branding"">
     <h1>Worrysome.com</h1>
     <blockquote><p>Don' worry 'bout a thing...</p></blockquote>
     <p>Take the weight of the world off your shoulders.</p>
 </div>

Applying a little positioning and z-index magic we can both set the position of these elements inside their positioning context and their stacking order. As we are going to use background images made from transparent PNGs, each element will allow another further down the stacking order to show through. This makes for some novel effects, particularly in liquid layouts.

(Ed: We’re using n below to represent whatever values you require for your specific design.) 

#branding {
    position: relative;
    width: n;
    height: n;
    background-image: url(n);
 }

 #branding>h1 {
    position: absolute;
    left: n;
    top: n;
    width: n;
    height: n;
    background-image: url(h1.png);
    text-indent: n;
 }

 #branding>blockquote {
    position: absolute;
    left: n;
    top: n;
    width: n;
    height: n;
    background-image: url(bq.png);
    text-indent: n;

 }

 #branding>p {
    position: absolute;
    right: n;
    top: n;
    width: n;
    height: n;
    background-image: url(p.png);
    text-indent: n;
 }

Next we can begin to see how the three elements build upon each other.


1. Elements outlined


2. Positioned elements overlayed to show context


3. Our final result

Multiple stacking orders

Not only can elements within a positioning context be given a z-index, but those positioning contexts themselves can also be stacked.


Two positioning contexts, each with their own stacking order

Interestingly each stacking order is independent of that of either the root element or its siblings and we can exploit this to make complex layouts from just a few semantic elements. This technique was used heavily on my recent redesign of Karova.com.

Dissecting part of Karova.com

First the XHTML. The default template markup used for the site places <div id=""nav_main""> and <div id=""content""> as siblings inside their container.

<div id=""container"">
     <div id=""content"">
          <h2></h2>
          <p></p>
     </div>
     <div id=""nav_main""></div>
 </div>

By giving the navigation <div> a lower z-index than the content <div> we can ensure that the positioned content elements will always appear closest to the viewer, despite the fact that the navigation comes after the content in the source.

#content { 
     position: relative; 
     z-index: 2; 
 }

 #nav_main { 
     position: absolute; 
     z-index: 1; 
 }

Now applying absolute positioning with a negative top value to the <h2> and a higher z-index value than the following <p> ensures that the header sits not only on top of the navigation but also the styled paragraph which follows it.

h2 {
     position: absolute;
     z-index: 200;
     top: -n;
 }

 h2+p {
     position: absolute;
     z-index: 100;
     margin-top: -n;
     padding-top: n;
 }

334,Transitional vs. Strict Markup,"When promoting web standards, standardistas often talk about XHTML as being more strict than HTML. In a sense it is, since it requires that all elements are properly closed and that attribute values are quoted. But there are two flavours of XHTML 1.0 (three if you count the Frameset DOCTYPE, which is outside the scope of this article), defined by the Transitional and Strict DOCTYPEs. And HTML 4.01 also comes in those flavours.

The names reveal what they are about: Transitional DOCTYPEs are meant for those making the transition from older markup to modern ways. Strict DOCTYPEs are actually the default – the way HTML 4.01 and XHTML 1.0 were constructed to be used.

A Transitional DOCTYPE may be used when you have a lot of legacy markup that cannot easily be converted to comply with a Strict DOCTYPE. But Strict is what you should be aiming for. It encourages, and in some cases enforces, the separation of structure and presentation, moving the presentational aspects from markup to CSS. From the HTML 4 Document Type Definition:


	This is HTML 4.01 Strict DTD, which excludes the presentation attributes and elements that W3C expects to phase out as support for style sheets matures. Authors should use the Strict DTD when possible, but may use the Transitional DTD when support for presentation attribute and elements is required.


An additional benefit of using a Strict DOCTYPE is that doing so will ensure that browsers use their strictest, most standards compliant rendering modes.

Tommy Olsson provides a good summary of the benefits of using Strict over Transitional in Ten questions for Tommy Olsson at Web Standards Group:


	In my opinion, using a Strict DTD, either HTML 4.01 Strict or XHTML 1.0 Strict, is far more important for the quality of the future web than whether or not there is an X in front of the name. The Strict DTD promotes a separation of structure and presentation, which makes a site so much easier to maintain.


For those looking to start using web standards and valid, semantic markup, it is important to understand the difference between Transitional and Strict DOCTYPEs. For complete listings of the differences between Transitional and Strict DOCTYPEs, see XHTML: Differences between Strict & Transitional, Comparison of Strict and Transitional XHTML, and XHTML1.0 Element Attributes by DTD.

Some of the differences are more likely than others to cause problems for developers moving from a Transitional DOCTYPE to a Strict one, and I’d like to mention a few of those.

Elements that are not allowed in Strict DOCTYPEs


	center
	font
	iframe
	strike
	u


Attributes not allowed in Strict DOCTYPEs


	align (allowed on elements related to tables: col, colgroup, tbody, td, tfoot, th, thead, and tr)
	language
	background
	bgcolor
	border (allowed on table)
	height (allowed on img and object)
	hspace
	name (allowed in HTML 4.01 Strict, not allowed on form and img in XHTML 1.0 Strict)
	noshade
	nowrap
	target
	text, link, vlink, and alink
	vspace
	width (allowed on img, object, table, col, and colgroup)


Content model differences

An element type’s content model describes what may be contained by an instance of the element type. The most important difference in content models between Transitional and Strict is that blockquote, body, and form elements may only contain block level elements. A few examples:


	text and images are not allowed immediately inside the body element, and need to be contained in a block level element like p or div
	input elements must not be direct descendants of a form element
	text in blockquote elements must be wrapped in a block level element like p or div


Go Strict and move all presentation to CSS

Something that can be helpful when doing the transition from Transitional to Strict DOCTYPEs is to focus on what each element of the page you are working on is instead of how you want it to look.

333,The Attribute Selector for Fun and (no ad) Profit,"If I had a favourite CSS selector, it would undoubtedly be the attribute selector (Ed: You really need to get out more). For those of you not familiar with the attribute selector, it allows you to style an element based on the existence, value or partial value of a specific attribute.

At it’s very basic level you could use this selector to style an element with particular attribute, such as a title attribute.

<abbr title=""Cascading Style Sheets"">CSS</abbr>

In this example I’m going to make all <abbr> elements with a title attribute grey. I am also going to give them a dotted bottom border that changes to a solid border on hover. Finally, for that extra bit of feedback, I will change the cursor to a question mark on hover as well. 

abbr[title] {
     color: #666;
     border-bottom: 1px dotted #666;
 }

 abbr[title]:hover {
     border-bottom-style: solid;
     cursor: help;
 }

This provides a nice way to show your site users that <abbr> elements with title tags are special, as they contain extra, hidden information.

Most modern browsers such as Firefox, Safari and Opera support the attribute selector. Unfortunately Internet Explorer 6 and below does not support the attribute selector, but that shouldn’t stop you from adding nice usability embellishments to more modern browsers.

Internet Explorer 7 looks set to implement this CSS2.1 selector, so expect to see it become more common over the next few years.

Styling an element based on the existence of an attribute is all well and good, but it is still pretty limited. Where attribute selectors come into their own is their ability to target the value of an attribute. You can use this for a variety of interesting effects such as styling VoteLinks.

VoteWhats?

If you haven’t heard of VoteLinks, it is a microformat that allows people to show their approval or disapproval of a links destination by adding a pre-defined keyword to the rev attribute.

For instance, if you had a particularly bad meal at a restaurant, you could signify your dissaproval by adding a rev attribute with a value of vote-against.

<a href=""http://www.mommacherri.co.uk/"" rev=""vote-against"">Momma Cherri's</a>

You could then highlight these links by adding an image to the right of these links.

a[rev=""vote-against""]{
     padding-right: 20px;
     background: url(images/vote-against.png) no-repeat right top;
}

This is a useful technique, but it will only highlight VoteLinks on sites you control. This is where user stylesheets come into effect. If you create a user stylesheet containing this rule, every site you visit that uses VoteLinks will receive your new style.

Cool huh?

However my absolute favourite use for attribute selectors is as a lightweight form of ad blocking. Most online adverts conform to industry-defined sizes. So if you wanted to block all banner-ad sized images, you could simply add this line of code to your user stylesheet.

img[width=""468""][height=""60""],
img[width=""468px""][height=""60px""]  {
     display: none !important;
}

To hide any banner-ad sized element, such as flash movies, applets or iFrames, simply apply the above rule to every element using the universal selector.

*[width=""468""][height=""60""], *[width=""468px""][height=""60px""]  {
     display: none !important;
}

Just bare in mind when using this technique that you may accidentally hide something that isn’t actually an advert; it just happens to be the same size.

The Interactive Advertising Bureau lists a number of common ad sizes. Using these dimensions, you can create stylesheet that blocks all the popular ad formats. Apply this as a user stylesheet and you never need to suffer another advert again.

321,Tables with Style,"It might not seem like it but styling tabular data can be a lot of fun. From a semantic point of view, there are plenty of elements to tie some style into. You have cells, rows, row groups and, of course, the table element itself. Adding CSS to a paragraph just isn’t as exciting.

Where do I start?

First, if you have some tabular data (you know, like a spreadsheet with rows and columns) that you’d like to spiffy up, pop it into a table — it’s rightful place!

To add more semantics to your table — and coincidentally to add more hooks for CSS — break up your table into row groups. There are three types of row groups: the header (thead), the body (tbody) and the footer (tfoot). You can only have one header and one footer but you can have as many table bodies as is appropriate.

Sample table example

Inspiration

Table Striping

To improve scanning information within a table, a common technique is to style alternating rows. Also known as zebra tables. Whether you apply it using a class on every other row or turn to JavaScript to accomplish the task, a handy-dandy trick is to use a semi-transparent PNG as your background image. This is especially useful over patterned backgrounds. 

tbody tr.odd td {
     background:transparent url(background.png) repeat top left;
 }

 * html tbody tr.odd td {
     background:#C00;
     filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(
          src='background.png', sizingMethod='scale');
 }

We turn off the default background and apply our PNG hack to have this work in Internet Explorer. 

Styling Columns

Did you know you could style a column? That’s right. You can add special column (col) or column group (colgroup) elements. With that you can add border or background styles to the column.

<table>
     <col id=""ingredients"">
     <col id=""serve12"">
     <col id=""serve24"">
 ...

Check out the example.

Fun with Backgrounds

Pop in a tiled background to give your table some character! Internet Explorer’s PNG hack unfortunately only works well when applied to a cell.

To figure out which background will appear over another, just remember the hierarchy:

 (bottom) Table → Column → Row Group → Row → Cell (top)

The Future is Bright

Once browser-makers start implementing CSS3, we’ll have more power at our disposal. Just with :first-child and :last-child, you can pull off a scalable version of our previous table with rounded corners and all — unfortunately, only Firefox manages to pull this one off successfully. And the selector the masses are clamouring for, nth-child, will make zebra tables easy as eggnog.",2005,Jonathan Snook,jonathansnook,2005-12-19T00:00:00+00:00,https://24ways.org/2005/tables-with-style/,code
328,Swooshy Curly Quotes Without Images,"The problem

Take a quote and render it within blockquote tags, applying big, funky and stylish curly quotes both at the beginning and the end without using any images – at all.

The traditional way

Feint background images under the text, or an image in the markup housed in a little float. Often designers only use the opening curly quote as it’s just too difficult to float a closing one.

Why is the traditional way bad?

Well, for a start there are no actual curly quotes in the text (unless you’re doing some nifty image replacement). Thus with CSS disabled you’ll only have default blockquote styling to fall back on. Secondly, images don’t resize, so scaling text will have no affect on your graphic curlies.

The solution

Use really big text. Then it can be resized by the browser, resized using CSS, and even be restyled with a new font style if you fancy it. It’ll also make sense when CSS is unavailable.

The problem

Creating “Drop Caps” with CSS has been around for a while (Big Dan Cederholm discusses a neat solution in that first book of his), but drop caps are normal characters – the A to Z or 1 to 10 – and these can all be pulled into a set space and do not serve up a ton of whitespace, unlike punctuation characters.

Curly quotes aren’t like traditional characters. Like full stops, commas and hashes they float within the character space and leave lots of dead white space, making it bloody difficult to manipulate them with CSS. Styles generally fit around text, so cutting into that character is tricky indeed. Also, all that extra white space is going to push into the quote text and make it look pretty uneven. This grab highlights the actual character space:



See how this is emphasized when we add a normal alphabetical character within the span. This is what we’re dealing with here:



Then, there’s size. Call in a curly quote at less than 300% font-size and it ain’t gonna look very big. The white space it creates will be big enough, but the curlies will be way too small. We need more like 700% (as in this example) to make an impression, but that sure makes for a big character space.

Prepare the curlies

Firstly, remove the opening “ from the quote. Replace it with the opening curly quote character entity “. Then replace the closing “ with the entity reference for that, which is ”. Now at least the curlies will look nice and swooshy.

Add the hooks

Two reasons why we aren’t using :first-letter pseudo class to manipulate the curlies. Firstly, only CSS2-friendly browsers would get what we’re doing, and secondly we need to affect the last “letter” of our text also – the closing curly quote.

So, add a span around the opening curly, and a second span around the closing curly, giving complete control of the characters:

<blockquote><span class=""bqstart"">“</span>Speech marks. Curly quotes. That annoying thing cool people do with their fingers to emphasize a buzzword, shortly before you hit them.<span class=""bqend"">”</span></blockquote>

So far nothing will look any different, aside form the curlies looking a bit nicer. I know we’ve just added extra markup, but the benefits as far as accessibility are concerned are good enough for me, and of course there are no images to download.

The CSS

OK, easy stuff first. Our first rule .bqstart floats the span left, changes the color, and whacks the font-size up to an exuberant 700%. Our second rule .bqend does the same tricks aside from floating the curly to the right.

.bqstart {
     float: left;
     font-size: 700%;
     color: #FF0000;
 }

 .bqend {
     float: right;
     font-size: 700%;
     color: #FF0000;
 }

That gives us this, which is rubbish. I’ve highlighted the actual span area with outlines:



Note that the curlies don’t even fit inside the span! At this stage on IE 6 PC you won’t even see the quotes, as it only places focus on what it thinks is in the div. Also, the quote text is getting all spangled.

Fiddle with margin and padding

Think of that span outline box as a window, and that you need to position the curlies within that window in order to see them. By adding some small adjustments to the margin and padding it’s possible to position the curlies exactly where you want them, and remove the excess white space by defining a height:

.bqstart {
     float: left;
     height: 45px;
     margin-top: -20px;
     padding-top: 45px;
     margin-bottom: -50px;
     font-size: 700%;
     color: #FF0000;
 }

 .bqend {
     float: right;
     height: 25px;
     margin-top: 0px;
     padding-top: 45px;
     font-size: 700%;
     color: #FF0000;
 }

I wanted the blocks of my curlies to align with the quote text, whereas you may want them to dig in or stick out more. Be aware however that my positioning works for IE PC and Mac, Firefox and Safari. Too much tweaking seems to break the magic in various browsers at various times. Now things are fitting beautifully:

I must admit that the heights, margins and spacing don’t make a lot of sense if you analyze them. This was a real trial and error job. Get it working on Safari, and IE would fail. Sort IE, and Firefox would go weird.

Finished

The final thing looks ace, can be resized, looks cool without styles, and can be edited with CSS at any time. Here’s a real example (note that I’m specifying Lucida Grande and then Verdana for my curlies):

 “Speech marks. Curly quotes. That annoying thing cool people do with their fingers to emphasize a buzzword, shortly before you hit them.”

Browsers happy

As I said, too much tweaking of margins and padding can break the effect in some browsers. Even now, Firefox insists on dropping the closing curly by approximately 6 or 7 pixels, and if I adjust the padding for that, it’ll crush it into the text on Safari or IE. Weird. Still, as I close now it seems solid through resizing tests on Safari, Firefox, Camino, Opera and IE PC and Mac. Lovely.

It’s probably not perfect, but together we can beat the evil typographic limitations of the web and walk together towards a brighter, more aligned world.

331,Splintered Striper,"Back in March 2004, David F. Miller demonstrated a little bit of DOM scripting magic in his A List Apart article Zebra Tables.

His script programmatically adds two alternating CSS background colours to table rows, making them more readable and visually pleasing, while saving the document author the tedious task of manually assigning the styling to large static data tables.

Although David’s original script performs its duty well, it is nonetheless very specific and limited in its application. It only:


	works on a single table, identified by its id, with at least a single tbody section
	assigns a background colour
	allows two colours for odd and even rows
	acts on data cells, rather than rows, and then only if they have no class or background colour already defined


Taking it further

In a recent project I found myself needing to apply a striped effect to a medium sized unordered list. Instead of simply modifying the Zebra Tables code for this particular case, I decided to completely recode the script to make it more generic.

Being more general purpose, the function in my splintered striper experiment is necessarily more complex. Where the original script only expected a single parameter (the id of the target table), the new function is called as follows:

striper('[parent element tag]','[parent element class or null]','[child element tag]','[comma separated list of classes]')

This new, fairly self-explanatory function:


	targets any type of parent element (and, if specified, only those with a certain class)
	assigns two or more classes (rather than just two background colours) to the child elements inside the parent
	preserves any existing classes already assigned to the child elements


See it in action

View the demonstration page for three usage examples. For simplicity’s sake, we’re making the calls to the striper function from the body’s onload attribute. In a real deployment situation, we would look at attaching a behaviour to the onload programmatically — just remember that, as we need to pass variables to the striper function, this would involve creating a wrapper function which would then be attached…something like:

function stripe() {
    striper('tbody','splintered','tr','odd,even');
}

window.onload=stripe;

A final thought

Just because the function is called striper does not mean that it’s limited to purely applying a striped look; as it’s more of a general purpose “alternating class assignment” script, you can achieve a whole variety of effects with it.",2005,Patrick Lauke,patricklauke,2005-12-15T00:00:00+00:00,https://24ways.org/2005/splintered-striper/,code
317,"Putting the World into ""World Wide Web""","Despite the fact that the Web has been international in scope from its inception, the predominant mass of Web sites are written in English or another left-to-right language. Sites are typically designed visually for Western culture, and rely on an enormous body of practices for usability, information architecture and interaction design that are by and large centric to the Western world.

There are certainly many reasons this is true, but as more and more Web sites realize the benefits of bringing their products and services to diverse, global markets, the more demand there will be on Web designers and developers to understand how to put the World into World Wide Web.

Internationalization

According to the W3C, Internationalization is:


	“…the design and development of a product, application or document content that enables easy localization for target audiences that vary in culture, region, or language.”


Many Web designers and developers have at least heard, if not read, about Internationalization. We understand that the Web is in fact worldwide, but many of us never have the opportunity to work with Internationalization. Or, when we do, think of it in purely technical terms, such as “which character set do I use?”

At first glance, it might seem to many that Internationalization is the act of making Web sites available to international audiences. And while that is in fact true, this isn’t done by broad-stroking techniques and technologies. Instead, it involves a far more narrow understanding of geographical, cultural and linguistic differences in specific areas of the world. This is referred to as localization and is the act of making a Web site make sense in the context of the region, culture and language(s) the people using the site are most familiar with.

Internationalization itself includes the following technical tasks:


	Ensuring no barrier exists to the localization of sites. Of critical importance in the planning stages of a site for Internationalized audiences, the role of the developer is to ensure that no barrier exists. This means being able to perform such tasks as enabling Unicode and making sure legacy character encodings are properly handled.
	Preparing markup and CSS with Internationalization in mind. The earlier in the site development process this occurs, the better. Issues such as ensuring that you can support bidirectional text, identifying language, and using CSS to support non-Latin typographic features.
	Enabling code to support local, regional, language or culturally related references. Examples in this category would include time/date formats, localization of calendars, numbering systems, sorting of lists and managing international forms of addresses.
	Empowering the user. Sites must be architected so the user can easily choose or implement the localized alternative most appropriate to them.


Localization

According to the W3C, Localization is the:


	…adaptation of a product, application or document content to meet the language, cultural and other requirements of a specific target market (a “locale”).


So here’s where we get down to thinking about the more sociological and anthropological concerns. Some of the primary localization issues are:


	Numeric formats. Different languages and cultures use numbering systems unlike ours. So, any time we need to use numbers, such as in an ordered list, we have to have a means of representing the accurate numbering system for the locale in question.
	Money, honey!  That’s right. I’ve got a pocketful of ugly U.S. dollars (why is U.S. money so unimaginative?). But I also have a drawer full of Japanese Yen, Australian Dollars, and Great British Pounds. Currency, how it’s calculated and how it’s represented is always a consideration when dealing with localization.
	Using symbols, icons and colors properly. Using certain symbols or icons on sites where they might offend or confuse is certainly not in the best interest of a site that wants to sell or promote a product, service or information type. Moreover, the colors we use are surprisingly persuasive – or detrimental. Think about colors that represent death, for example. In many parts of Asia, white is the color of death. In most of the Western world, black represents death. For Catholic Europe, shades of purple (especially lavender) have represented Christ on the cross and mourning since at least Victorian times. When Walt Disney World Europe launched an ad campaign using a lot of purple and very glitzy imagery, millions of dollars were lost as a result of this seeming subtle issue. Instead of experiencing joy and celebration at the ads, the European audience, particularly the French, found the marketing to be overly American, aggressive, depressing and basically unappealing. Along with this and other cultural blunders, Disney Europe has become a well-known case study for businesses wishing to become international. By failing to understand localization differences, and how powerful color and imagery act on the human psyche, designers and developers are put to more of a disadvantage when attempting to communicate with a given culture.
	Choosing appropriate references to objects and ideas. What seems perfectly natural in one culture in terms of visual objects and ideas can get confused in another environment. One of my favorite cases of this has to do with Gerber baby food. In the U.S., the baby food is marketed using a cute baby on the package. Most people in the U.S. culturally do not make an immediate association that what is being represented on the label is what is inside the container. However, when Gerber expanded to Africa, where many people don’t read, and where visual associations are less abstract, people made the inference that a baby on the cover of a jar of food represented what is in fact in the jar. You can imagine how confused and even angry people became. Using such approaches as a marketing ploy in the wrong locale can and will render the marketing a failure.


As you can see, the act of localization is one that can have profound impact on the success of a business or organization as it seeks to become available to more and more people across the globe.

Rethinking Design in the Context of Culture

While well-educated designers and those individuals working specifically for companies that do a lot of localization understand these nuances, most of us don’t get exposed to these ideas. Yet, we begin to see how necessary it becomes to have an awareness of not just the technical aspects of Internationalization, but the socio-cultural ones within localization.

What’s more, the bulk of information we have when it comes to designing sites typically comes from studies and work done on sites built in English and promoted to Western culture at large. We’re making a critical mistake by not including diverse languages and cultural issues within our usability and information architecture studies.

Consider the following design from the BBC:



In this case, we’re dealing with English, which is read left to right. We are also dealing with U.K. cultural norms. Notice the following:


	Location of of navigation
	Use of the color red
	Use of diverse symbols
	Mix of symbols, icons and photos
	Location of Search


Now look at this design, which is the Arabic version of the BBC News, read right to left, and dealing with cultural norms within the Arabic-speaking world.



Notice the following:


	Location of of navigation (location switches to the right)
	Use of the color blue (blue is considered the “safest” global color)
	No use of symbols and icons whatsoever
	Limitation of imagery to photos
	In most cases, the photos show people, not objects
	Location of Search


Admittedly, some choices here are more obvious than others in terms of why they were made. But one thing that stands out is that the placement of search is the same for both versions. Is this the result of a specific localization decision, or based on what we believe  about usability at large? This is exactly the kind of question that designers working on localization have to seek answers to, instead of relying on popular best practices and belief systems that exist for English-only Web sites.

It’s a Wide World Web After All

From this brief article on Internationalization, it becomes apparent that the art and science of creating sites for global audiences requires a lot more preparation and planning than one might think at first glance.  Developers and designers not working to address these issues specifically due to time or awareness will do well to at least understand the basic process of making sites more culturally savvy, and better prepared for any future global expansion.

One thing is certain: We not only are on a dramatic learning curve for designing and developing Web sites as it is, the need to localize sites is going to become more and more a part of the day to day work. Understanding aspects of what makes a site international and local will not only help you expand your skill set and make you more marketable, but it will also expand your understanding of the world and the people within it, how they relate to and use the Web, and how you can help make their experience the best one possible.",2005,Molly Holzschlag,mollyholzschlag,2005-12-09T00:00:00+00:00,https://24ways.org/2005/putting-the-world-into-world-wide-web/,ux
336,Practical Microformats with hCard,"You’ve probably heard about microformats over the last few months. You may have even read the easily digestible introduction at Digital Web Magazine, but perhaps you’ve not found time to actually implement much yet. That’s understandable, as it can sometimes be difficult to see exactly what you’re adding by applying a microformat to a page. Sure, you’re semantically enhancing the information you’re marking up, and the Semantic Web is a great idea and all, but what benefit is it right now, today? 

Well, the answer to that question is simple: you’re adding lots of information that can be and is being used on the web here and now. The big ongoing battle amongst the big web companies if one of territory over information. Everyone’s grasping for as much data as possible. Some of that information many of us are cautious to give away, but a lot of is happy to be freely available. Of the data you’re giving away, it makes sense to give it as much meaning as possible, thus enabling anyone from your friends and family to the giant search company down the road to make the most of it.

Ok, enough of the waffle, let’s get working.

Introducing hCard

You may have come across hCard. It’s a microformat for describing contact information (or really address book information) from within your HTML. It’s based on the vCard format, which is the format the contacts/address book program on your computer uses. All the usual fields are available – name, address, town, website, email, you name it.

If you’re running Firefox and Greasemonkey (or if you can, just to try this out), install this user script. What it does is look for instances of the hCard microformat in a page, and then add in a link to pass any hCards it finds to a web service which will convert it to a vCard. Take a look at the About the author box at the bottom of this article. It’s a hCard, so you should be able to click the icon the user script inserts and add me to your Outlook contacts or OS X Address Book with just a click.

So microformats are useful after all. Free microformats all round!

Implementing hCard

This is the really easy bit. All the hCard microformat is, is a bunch of predefined class names that you apply to the markup you’ve probably already got around your contact information. Let’s take the example of the About the author box from this article. Here’s how the markup looks without hCard:

<div class=""bio"">
     <h3>About the author</h3>
     <p>Drew McLellan is a web developer, author and no-good swindler from 
     just outside London, England. At the 
     <a href=""http://www.webstandards.org/"">Web Standards Project</a> he works 
     on press, strategy and tools. Drew keeps a 
     <a href=""http://www.allinthehead.com/"">personal weblog</a> covering web 
     development issues and themes.</p>
</div>

This is a really simple example because there’s only two key bits of address book information here:- my name and my website address. Let’s push it a little and say that the Web Standards Project is the organisation I work for – that gives us Name, Company and URL.

To kick off an hCard, you need a containing object with a class of vcard. The div I already have with a class of bio is perfect for this – all it needs to do is contain the rest of the contact information.

The next thing to identify is my name. hCard uses a class of fn (meaning Full Name) to identify a name. As is this case there’s no element surrounding my name, we can just use a span. These changes give us:

<div class=""bio vcard"">
     <h3>About the author</h3>
     <p><span class=""fn"">Drew McLellan</span> is a web developer...

The two remaining items are my URL and the organisation I belong to. The class names designated for those are url and org respectively. As both of those items are links in this case, I can apply the classes to those links. So here’s the finished hCard.

<div class=""bio vcard"">
     <h3>About the author</h3>
     <p><span class=""fn"">Drew McLellan</span> is a web developer, author and 
     no-good swindler from just outside London, England. 
     At the <a class=""org"" href=""http://www.webstandards.org/"">Web Standards Project</a> 
     he works on press, strategy and tools. Drew keeps a 
     <a class=""url"" href=""http://www.allinthehead.com/"">personal weblog</a> covering web 
     development issues and themes.</p>
</div>

OK, that was easy. By just applying a few easy class names to the HTML I was already publishing, I’ve implemented an hCard that right now anyone with Greasemonkey can click to add to their address book, that Google and Yahoo! and whoever else can index and work out important things like which websites are associated with my name if they so choose (and boy, will they so choose), and in the future who knows what. In terms of effort, practically nil.

Where next?

So that was a trivial example, but to be honest it doesn’t really get much more complex even with the most pernickety permutations. Because hCard is based on vCard (a mature and well thought-out standard), it’s all tried and tested. Here’s some good next steps.


	Play with the hCard Creator
	Take a deep breath and read the spec
	Start implementing hCard as you go on your own projects – it takes very little time


hCard is just one of an ever-increasing number of microformats. If this tickled your fancy, I suggest subscribing to the microformats site in your RSS reader to keep in touch with new developments.

What’s the take-away?

The take-away is this. They may sound like just more Web 2-point-HoHoHo hype, but microformats are a well thought-out, and easy to implement way of adding greater depth to the information you publish online. They have some nice benefits right away – certainly at geek-level – but in the longer term they become much more significant. We’ve been at this long enough to know that the web has a long, long memory and that what you publish today will likely be around for years. But putting the extra depth of meaning into your documents now you can help guard that they’ll continue to be useful in the future, and not just a bunch of flat ASCII.",2005,Drew McLellan,drewmclellan,2005-12-06T00:00:00+00:00,https://24ways.org/2005/practical-microformats-with-hcard/,code
335,Naughty or Nice? CSS Background Images,"Web Standards based development involves many things – using semantically sound HTML to provide structure to our documents or web applications, using CSS for presentation and layout, using JavaScript responsibly, and of course, ensuring that all that we do is accessible and interoperable to as many people and user agents as we can.

This we understand to be good. 

And it is good. 

Except when we don’t clearly think through the full implications of using those techniques.

Which often happens when time is short and we need to get things done.

Here are some naughty examples of CSS background images with their nicer, more accessible counterparts.

Transaction related messages

I’m as guilty of this as others (or, perhaps, I’m the only one that has done this, in which case this can serve as my holiday season confessional)  We use lovely little icons to show status messages for a transaction to indicate if the action was successful, or was there a warning or error? For example:

“Your postal/zip code was not in the correct format.”

Notice that we place a nice little icon there, and use background colours and borders to convey a specific message: there was a problem that needs to be fixed. Notice that all of this visual information is now contained in the CSS rules for that div:

<div class=""error"">
     <p>Your postal/zip code was not in the correct format.</p>
 </div>

 div.error {
     background: #ffcccc url(../images/error_small.png) no-repeat 5px 4px;
     color: #900;
     border-top: 1px solid #c00;
     border-bottom: 1px solid #c00;
     padding: 0.25em 0.5em 0.25em 2.5em;
     font-weight: bold;
 }

Using this approach also makes it very easy to create a div.success and div.warning CSS rules meaning we have less to change in our HTML.

Nice, right?

No. Naughty. 

Visual design communicates

The CSS is being used to convey very specific information. The choice of icon, the choice of background colour and borders tell us visually that there is something wrong. 

With the icon as a background image – there is no way to specify any alt text for the icon, and significant meaning is lost. A screen reader user, for example, misses the fact that it is an “error.” 

The solution? Ask yourself: what is the bare minimum needed to indicate there was an error? Currently in the absence of CSS there will be no icon – which (I’m hoping you agree) is critical to communicating there was an error.

The icon should be considered content and not simply presentational.

The borders and background colour are certainly much less critical – they belong in the CSS.

Lets change the code to place the image directly in the HTML and using appropriate alt text to better communicate the meaning of the icon to all users:

<div class=""bettererror"">
     <img src=""images/error_small.png"" alt=""Error"" />
     <p>Your postal/zip code was not in the correct format.</p>
 </div>

 div.bettererror {
     background-color: #ffcccc;
     color: #900;
     border-top: 1px solid #c00;
     border-bottom: 1px solid #c00;
     padding: 0.25em 0.5em 0.25em 2.5em;
     font-weight: bold;
     position: relative;
     min-height: 1.25em;
 }

 div.bettererror img {
     display: block;
     position: absolute;
     left: 0.25em;
     top: 0.25em;
     padding: 0;
     margin: 0;
 }

 div.bettererror p {
     position: absolute;
     left: 2.5em;
     padding: 0;
     margin: 0;
 }

Compare these two examples of transactional messages

Status of a Record

This example is pretty straightforward. Consider the following: a real estate listing on a web site. There are three “states” for a listing: new, normal, and sold. Here’s how they look:

Example of a New Listing

Example of A Sold Listing

If we (forgive the pun) blindly apply the “use a CSS background image” technique we clearly run into problems with the new and sold images – they actually contain content with no way to specify an alternative when placed in the CSS.

In this case of the “new” image, we can use the same strategy as we used in the first example (the transaction result). The “new” image should be considered content and is placed in the HTML as part of the <h2>...</h2> that identifies the listing.

However when considering the “sold” listing, there are less changes to be made to keep the same look by leaving the “SOLD” image as a background image and providing the equivalent information elsewhere in the listing – namely, right in the heading.

For those that can’t see the background image, the status is communicated clearly and right away. A screen reader user that is navigating by heading or viewing a listing will know right away that a particular property is sold.

Of note here is that in both cases (new and sold) placing the status near the beginning of the record helps with a zoom layout as well.

Better Example of A Sold Listing

Summary

Remember: in the holiday season, its what you give that counts!! Using CSS background images is easy and saves time for you but think of the children. And everyone else for that matter… 

CSS background images should only be used for presentational images, not for those that contain content (unless that content is already represented and readily available elsewhere).",2005,Derek Featherstone,derekfeatherstone,2005-12-20T00:00:00+00:00,https://24ways.org/2005/naughty-or-nice-css-background-images/,code
322,Introduction to Scriptaculous Effects,"Gather around kids, because this year, much like in that James Bond movie with Denise Richards, Christmas is coming early… in the shape of scrumptuous smooth javascript driven effects at your every whim.

Now what I’m going to do, is take things down a notch. Which is to say, you don’t need to know much beyond how to open a text file and edit it to follow this article. Personally, I for instance can’t code to save my life.

Well, strictly speaking, that’s not entirely true. If my life was on the line, and the code needed was really simple and I wasn’t under any time constraints, then yeah maybe I could hack my way out of it

But my point is this: I’m not a programmer in the traditional sense of the word. In fact, what I do best, is scrounge code off of other people, take it apart and then put it back together with duct tape, chewing gum and dumb blind luck.

No, don’t run! That happens to be a good thing in this case. You see, we’re going to be implementing some really snazzy effects (which are considerably more relevant than most people are willing to admit) on your site, and we’re going to do it with the aid of Thomas Fuchs’ amazing Script.aculo.us library. And it will be like stealing candy from a child.

What Are We Doing?

I’m going to show you the very basics of implementing the Script.aculo.us javascript library’s Combination Effects. These allow you to fade elements on your site in or out, slide them up and down and so on.

Why Use Effects at All?

Before get started though, let me just take a moment to explain how I came to see smooth transitions as something more than smoke and mirror-like effects included for with little more motive than to dazzle and make parents go ‘uuh, snazzy’.

Earlier this year, I had the good fortune of meeting the kind, gentle and quite knowledgable Matt Webb at a conference here in Copenhagen where we were both speaking (though I will be the first to admit my little talk on Open Source Design was vastly inferior to Matt’s talk). Matt held a talk called Fixing Broken Windows (based on the Broken Windows theory), which really made an impression on me, and which I have since then referred back to several times.

You can listen to it yourself, as it’s available from Archive.org. Though since Matt’s session uses many visual examples, you’ll have to rely on your imagination for some of the examples he runs through during it. Also, I think it looses audio for a few seconds every once in a while.

Anyway, one of the things Matt talked a lot about, was how our eyes are wired to react to movement. The world doesn’t flickr. It doesn’t disappear or suddenly change and force us to look for the change. Things move smoothly in the real world. They do not pop up.

How it Works

Once the necessary files have been included, you trigger an effect by pointing it at the ID of an element. Simple as that.

Implementing the Effects

So now you know why I believe these effects have a place in your site, and that’s half the battle. Because you see, actually getting these effects up and running, is deceptively simple.

First, go and download the latest version of the library (as of this writing, it’s version 1.5 rc5). Unzip itand open it up.

Now we’re going to bypass the instructions in the readme file. Script.aculo.us can do a bunch of quite advanced things, but all we really want from it is its effects. And by sidestepping the rest of the features, we can shave off roughly 80KB of unnecessary javascript, which is well worth it if you ask me.

As with Drew’s article on Easy Ajax with Prototype, script.aculo.us also uses the Prototype framework by  Sam Stephenson. But contrary to Drew’s article, you don’t have to download Prototype, as a version comes bundled with script.aculo.us (though feel free to upgrade to the latest version if you so please).

So in the unzipped folder, containing the script.aculo.us files and folder, go into ‘lib’ and grab the ‘prototype.js’ file. Move it to whereever you want to store the javascript files. Then fetch the ‘effects.js’ file from the ‘src’ folder and put it in the same place.

To make things even easier for you to get this up and running, I have prepared a small javascript snippet which does some checking to see what you’re trying to do. The script.aculo.us effects are all either ‘turn this off’ or ‘turn this on’. What this snippet does, is check to see what state the target currently has (is it on or off?) and then use the necessary effect.

You can either skip to the end and download the example code, or copy and paste this code into a file manually (I’ll refer to that file as combo.js):

Effect.OpenUp = function(element) {
     element = $(element);
     new Effect.BlindDown(element, arguments[1] || {});
 }

 Effect.CloseDown = function(element) {
     element = $(element);
     new Effect.BlindUp(element, arguments[1] || {});
 }

 Effect.Combo = function(element) {
     element = $(element);
     if(element.style.display == 'none') { 
          new Effect.OpenUp(element, arguments[1] || {}); 
     }else { 
          new Effect.CloseDown(element, arguments[1] || {}); 
     }
 }

Currently, this code uses the BlindUp and BlindDown code, which I personally like, but there’s nothing wrong with you changing the effect-type into one of the other effects available.

Now, include the three files in the header of your code, like so:

<script src=""prototype.js"" type=""text/javascript""></script>
<script src=""effects.js"" type=""text/javascript""></script>
<script src=""combo.js"" type=""text/javascript""></script>

Now insert the element you want to use the effect on, like so:

<div id=""content"" style=""display: none;"">Lorem ipsum dolor sit amet.</div>

The above element will start out invisible, and when triggered will be revealed. If you want it to start visible, simply remove the style parameter.

And now for the trigger 

<a href=""javascript:Effect.Combo('content');"">Click Here</a>

And that, is pretty much it. Clicking the link should unfold the DIV targeted by the effect, in this case ‘content’.

Effect Options

Now, it gets a bit long-haired though. The documentation for script.aculo.us is next to non-existing, and because of that you’ll have to do some digging yourself to appreciate the full potentialof these effects.

First of all, what kind of effects are available? Well you can go to the demo page and check them out, or you can open the ‘effects.js’ file and have a look around, something I recommend doing regardlessly, to gain an overview of what exactly you’re dealing with.

If you dissect it for long enough, you can even distill some of the options available for the various effects. In the case of the BlindUp and BlindDown effect, which we’re using in our example (as triggered from combo.js), one of the things that would be interesting to play with would be the duration of the effect. If it’s too long, it will feel slow and unresponsive. Too fast and it will be imperceptible.

You set the options like so:

<a href=""javascript:Effect.Combo('content', {duration: .2});"">Click Here</a>

The change from the previous link being the inclusion of , {duration: .2}. In this case, I have lowered the duration to 0.2 second, to really make it feel snappy.

You can also go all-out and turn on all the bells and whistles of the Blind effect like so (slowed down to a duration of three seconds so you can see what’s going on):

<a href=""javascript:Effect.Combo('content', {duration: 3, scaleX: true, scaleContent: true});"">Click Here</a>

Conclusion

And that’s pretty much it. The rest is a matter of getting to know the rest of the effects and their options as well as finding out just when and where to use them. Remember the ancient Chinese saying: Less is more.

323,Introducing UDASSS!,"Okay. What’s that mean?

Unobtrusive Degradable Ajax Style Sheet Switcher!

Boy are you in for treat today ‘cause we’re gonna have a whole lotta Ajaxifida Unobtrucitosity CSS swappin’ Fun!

Okay are you really kidding? Nope. I’ve even impressed myself on this one. Unfortunately, I don’t have much time to tell you the ins and outs of what I actually did to get this to work. We’re talking JavaScript, CSS, PHP…Ajax. But don’t worry about that. I’ve always believed that a good A.P.I. is an invisible A.P.I… and this I felt I achieved. The only thing you need to know is how it works and what to do.

A Quick Introduction Anyway…

First of all, the idea is very simple. I wanted something just like what Paul Sowden put together in 
Alternative Style: Working With Alternate Style Sheets from Alistapart Magazine EXCEPT a few minor (not-so-minor actually) differences which I’ve listed briefly below:



	Allow users to switch styles without JavaScript enabled (degradable)
	Preventing the F.O.U.C. before the window ‘load’ when getting preferred styles
	Keep the JavaScript entirely off our markup (no onclick’s or onload’s)
	Make it very very easy to implement (ok, Paul did that too)


What I did to achieve this was used server-side cookies instead of JavaScript cookies. Hence, PHP. However this isn’t a “PHP style switcher” – which is where Ajax comes in. For the extreme technical folks, no, there is no xml involved here, or even a callback response. I only say Ajax because everyone knows what ‘it’ means. With that said, it’s the Ajax that sets the cookies ‘on the fly’. Got it? Awesome!

What you need

Luckily, I’ve done the work for you. It’s all packaged up in a nice zip file (at the end…keep reading for now) – so from here on out, 
just follow these instructions

As I’ve mentioned, one of the things we’ll be working with is PHP. So, first things first, open up a file called index and save it with a ‘.php’ extension.

Next, place the following text at the top of your document (even above your DOCTYPE)

<?php
 require_once('utils/style-switcher.php');
 // style sheet path[, media, title, bool(set as alternate)]
 $styleSheet = new AlternateStyles();
 $styleSheet->add('css/global.css','screen,projection'); // [Global Styles]
 $styleSheet->add('css/preferred.css','screen,projection','Wog Standard'); // [Preferred Styles]
 $styleSheet->add('css/alternate.css','screen,projection','Tiny Fonts',true); // [Alternate Styles]
 $styleSheet->add('css/alternate2.css','screen,projection','Big O Fonts',true); // // [Alternate Styles]
 $styleSheet->getPreferredStyles();
 ?>

The way this works is REALLY EASY. Pay attention closely.

Notice in the first line we’ve included our style-switcher.php file.

Next we instantiate a PHP class called AlternateStyles() which will allow us to configure our style sheets. 
So for kicks, let’s just call our object $styleSheet

As part of the AlternateStyles object, there lies a public method called add. So naturally with our $styleSheet object, we can call it to (da – da-da-da!) Add Style Sheets!

How the add() method works

The add method takes in a possible four arguments, only one is required. However, you’ll want to add some… since the whole point is working with alternate style sheets.

$path can simply be a uri, absolute, or relative path to your style sheet. $media adds a media attribute to your style sheets. $title gives a name to your style sheets (via title attribute).$alternate (which shows boolean) simply tells us that these are the alternate style sheets.

add() Tips

For all global style sheets (meaning the ones that will always be seen and will not be swapped out), simply use the add method as shown next to // [Global Styles].

To add preferred styles, do the same, but add a ‘title’.

To add the alternate styles, do the same as what we’ve done to add preferred styles, but add the extra boolean and set it to true.

Note following when adding style sheets


	Multiple global style sheets are allowed
	You can only have one preferred style sheet (That’s a browser rule)
	Feel free to add as many alternate style sheets as you like


Moving on

Simply add the following snippet to the <head> of your web document:

<script type=""text/javascript"" src=""js/prototype.js""></script>
 <script type=""text/javascript"" src=""js/common.js""></script>
 <script type=""text/javascript"" src=""js/alternateStyles.js""></script>
 <?php
 $styleSheet->drop();
 ?>

Nothing much to explain here. Just use your copy & paste powers.

How to Switch Styles

Whether you knew it or not, this baby already has the built in ‘ubobtrusive’ functionality that lets you switch styles by the drop of any link with a class name of ‘altCss‘. Just drop them where ever you like in your document as follows:

<a class=""altCss"" href=""index.php?css=Bog_Standard"">Bog Standard</a>
 <a class=""altCss"" href=""index.php?css=Really_Small_Fonts"">Small Fonts</a>
 <a class=""altCss"" href=""index.php?css=Large_Fonts"">Large Fonts</a>

Take special note where the file is linking to. Yep. Just linking right back to the page we’re on. The only extra parameters we pass in is a variable called ‘css’ – and within that we append the names of our style sheets.

Also take very special note on the names of the style sheets have an under_score to take place of any spaces we might have.

Go ahead… play around and change the style sheet on the example page. Try disabling JavaScript and refreshing your browser. Still works!

Cool eh?

327,Improving Form Accessibility with DOM Scripting,"The form label element is an incredibly useful little element – it lets you link the form field unquestionably with the descriptive label text that sits alongside or above it. This is a very useful feature for people using screen readers, but there are some problems with this element.

What happens if you have one piece of data that, for various reasons (validation, the way your data is collected/stored etc), needs to be collected using several form elements?

The classic example is date of birth – ideally, you’ll ask for the date of birth once but you may have three inputs, one each for day, month and year, that you also need to provide hints about the format required. The problem is that to be truly accessible you need to label each field. So you end up needing something to say “this is a date of birth”, “this is the day field”, “this is the month field” and “this is the day field”. Seems like overkill, doesn’t it? And it can uglify a form no end.

There are various ways that you can approach it (and I think I’ve seen them all). Some people omit the label and rely on the title attribute to help the user through; others put text in a label but make the text 1 pixel high and merging in to the background so that screen readers can still get that information. The most common method, though, is simply to set the label to not display at all using the CSS display:none property/value pairing (a technique which, for the time being, seems to work on most screen readers). But perhaps we can do more with this?

The technique I am suggesting as another alternative is as follows (here comes the pseudo-code):


	Start with a totally valid and accessible form
	Ensure that each form input has a label that is linked to its related form control
	Apply a class to any label that you don’t want to be visible (for example superfluous)


Then, through the magic of unobtrusive JavaScript/the DOM, manipulate the page as follows once the page has loaded:


	Find all the label elements that are marked as superfluous and hide them
	Find out what input element each of these label elements is related to
	Then apply a hint about formatting required for input (gleaned from the original, now-hidden label text) – add it to the form input as default text
	Finally, add in a behaviour that clears or selects the default text (as you choose)


So, here’s the theory put into practice – a date of birth, grouped using a fieldset, and with the behaviours added in using DOM, and here’s the JavaScript that does the heavy lifting. 

But why not just use display:none? As demonstrated at Juicy Studio, display:none seems to work quite well for hiding label elements. So why use a sledge hammer to crack a nut? In all honesty, this is something of an experiment, but consider the following:


	Using the DOM, you can add extra levels of help, potentially across a whole form – or even range of forms – without necessarily increasing your markup (it goes beyond simply hiding labels)
	Screen readers today may  identify a label that is set not to display, but they may not in the future – this might provide a way around
	By expanding this technique above, it might be possible to visually change the parent container that groups these items – in this case, a fieldset and legend, which are notoriously difficult to style consistently across different browsers – while still retaining the underlying semantic/logical structure


Well, it’s an idea to think about at least. How is it for you? How else might you use DOM scripting to improve the accessiblity or usability of your forms?",2005,Ian Lloyd,ianlloyd,2005-12-03T00:00:00+00:00,https://24ways.org/2005/improving-form-accessibility-with-dom-scripting/,code
316,Have Your DOM and Script It Too,"When working with the XMLHttpRequest object it appears you can only go one of three ways: 


	You can stay true to the colorful moniker du jour and stick strictly to the responseXML property
	You can play with proprietary – yet widely supported – fire and inject the value of responseText property into the innerHTML of an element of your choosing
	Or you can be eval() and parse JSON or arbitrary JavaScript delivered via responseText


But did you know that there’s a fourth option giving you the best of the latter two worlds? Mint uses this unmentioned approach to grab fresh HTML and run arbitrary JavaScript simultaneously. Without relying on eval(). “But wait-”, you might say, “when would I need to do this?” Besides the example below this technique is handy for things like tab groups that need initialization onload but miss the main onload event handler by a mile thanks to asynchronous scripting.

Consider the problem

Originally Mint used option 2 to refresh or load new tabs into individual Pepper panes without requiring a full roundtrip to the server. This was all well and good until I introduced the new Client Mode which when enabled allows anyone to view a Mint installation without being logged in. If voyeurs are afoot as Client Mode is disabled, the next time they refresh a pane the entire login page is inserted into the current document. That’s not very helpful so I needed a way to redirect the current document to the login page.



Enter the solution

Wouldn’t it be cool if browsers interpreted the contents of script tags crammed into innerHTML? Sure, but unfortunately, that just wasn’t meant to be. However like the body element, image elements have an onload event handler. When the image has fully loaded the handler runs the code applied to it. See where I’m going with this?

By tacking a tiny image (think single pixel, transparent spacer gif – shudder) onto the end of the HTML returned by our Ajax call, we can smuggle our arbitrary JavaScript into the existing document. The image is added to the DOM, and our stowaway can go to town.

<p>This is the results of our Ajax call.</p>
 <img src=""../images/loaded.gif"" alt="""" onload=""alert('Now that I have your attention...');"" />

Please be neat

So we’ve just jammed some meaningless cruft into our DOM. If our script does anything with images this addition could have some unexpected side effects. (Remember The Fly?) So in order to save that poor, unsuspecting element whose innerHTML we just swapped out from sharing Jeff Goldblum’s terrible fate we should tidy up after ourselves. And by using the removeChild method we do just that.

315,Edit-in-Place with Ajax,"Back on day one we looked at using the Prototype library to take all the hard work out of making a simple Ajax call. While that was fun and all, it didn’t go that far towards implementing something really practical. We dipped our toes in, but haven’t learned to swim yet.

So here is swimming lesson number one. Anyone who’s used Flickr to publish their photos will be familiar with the edit-in-place system used for quickly amending titles and descriptions on photographs. Hovering over an item turns its background yellow to indicate it is editable. A simple click loads the text into an edit box, right there on the page.



Prototype includes all sorts of useful methods to help reproduce something like this for our own projects. As well as the simple Ajax GETs we learned how to do last time, we can also do POSTs (which we’ll need here) and a whole bunch of manipulations to the user interface – all through simple library calls. Here’s what we’re building, so let’s do it.

Getting Started

There are two major components to this process; the user interface manipulation and the Ajax call itself. Our set-up is much the same as last time (you may wish to read the first article if you’ve not already done so). We have a basic HTML page which links in the prototype.js file and our own editinplace.js. Here’s what Santa dropped down my chimney: 

<!DOCTYPE html PUBLIC ""-//W3C//DTD XHTML 1.0 Strict//EN""
     ""http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"">
 <html xmlns=""http://www.w3.org/1999/xhtml"" xml:lang=""en"" lang=""en"">
 <head>
     <meta http-equiv=""Content-Type"" content=""text/html; charset=utf-8""/>
    <title>Edit-in-Place with Ajax</title>
     <link href=""editinplace.css"" rel=""Stylesheet"" type=""text/css"" />
     <script src=""prototype.js"" type=""text/javascript""></script>
     <script src=""editinplace.js"" type=""text/javascript""></script>    
</head> 
<body>
     <h1>Edit-in-place</h1>
     <p id=""desc"">Dashing through the snow on a one horse open sleigh.</p>
 </body>
 </html>

So that’s our page. The editable item is going to be the <p> called desc. The process goes something like this:


	Highlight the area onMouseOver
	Clear the highlight onMouseOut
	If the user clicks, hide the area and replace with a <textarea> and buttons
	Remove all of the above if the user cancels the operation
	When the Save button is clicked, make an Ajax POST and show that something’s happening
	When the Ajax call comes back, update the page with the new content


Events and Highlighting

The first step is to offer feedback to the user that the item is editable. This is done by shading the background colour when the user mouses over. Of course, the CSS :hover pseudo class is a straightforward way to do this, but for three reasons, I’m using JavaScript to switch class names.


	:hover isn’t supported on many elements in Internet Explorer for Windows
	I want to keep control over when the highlight switches off after an update, regardless of mouse position
	If JavaScript isn’t available we don’t want to end up with the CSS suggesting it might be


With this in mind, here’s how editinplace.js starts:

Event.observe(window, 'load', init, false);

 function init(){
     makeEditable('desc');
 }

 function makeEditable(id){
     Event.observe(id, 'click', function(){edit($(id))}, false);
     Event.observe(id, 'mouseover', function(){showAsEditable($(id))}, false);
     Event.observe(id, 'mouseout', function(){showAsEditable($(id), true)}, false);
 }

 function showAsEditable(obj, clear){
     if (!clear){
          Element.addClassName(obj, 'editable');
     }else{
          Element.removeClassName(obj, 'editable');
     }
 }

The first line attaches an onLoad event to the window, so that the function init() gets called once the page has loaded. In turn, init() sets up all the items on the page that we want to make editable. In this example I’ve just got one, but you can add as many as you like.

The function madeEditable() attaches the mouseover, mouseout and click events to the item we’re making editable. All showAsEditable does is add and remove the class name editable from the object. This uses the particularly cunning methods Element.addClassName() and Element.removeClassName() which enable you to cleanly add and remove effects without affecting any styling the object may otherwise have.

Oh, remember to add a rule for .editable to your style sheet:

.editable{
     color: #000;
     background-color: #ffffd3;
 }

The Switch

As you can see above, when the user clicks on an editable item, a call is made to the function edit(). This is where we switch out the static item for a nice editable textarea. Here’s how that function looks.

function edit(obj){
     Element.hide(obj);

     var textarea ='<div id=""' + obj.id + '_editor"">
          <textarea id=""' + obj.id + '_edit"" name=""' + obj.id + '"" rows=""4"" cols=""60"">'
          + obj.innerHTML + '</textarea>';

     var button = '<input id=""' + obj.id + '_save"" type=""button"" value=""SAVE"" /> OR 
          <input id=""' + obj.id + '_cancel"" type=""button"" value=""CANCEL"" /></div>';

     new Insertion.After(obj, textarea+button);

     Event.observe(obj.id+'_save', 'click', function(){saveChanges(obj)}, false);
     Event.observe(obj.id+'_cancel', 'click', function(){cleanUp(obj)}, false);

 }

The first thing to do is to hide the object. Prototype comes to the rescue with Element.hide() (and of course, Element.show() too). Following that, we build up the textarea and buttons as a string, and then use Insertion.After() to place our new editor underneath the (now hidden) editable object.

The last thing to do before we leave the user to edit is it attach listeners to the Save and Cancel buttons to call either the saveChanges() function, or to cleanUp() after a cancel.

In the event of a cancel, we can clean up behind ourselves like so:

function cleanUp(obj, keepEditable){
     Element.remove(obj.id+'_editor');
     Element.show(obj);
     if (!keepEditable) showAsEditable(obj, true);
 }

Saving the Changes

This is where all the Ajax fun occurs. Whilst the previous article introduced Ajax.Updater() for simple Ajax calls, in this case we need a little bit more control over what happens once the response is received. For this purpose, Ajax.Request() is perfect. We can use the onSuccess and onFailure parameters to register functions to handle the response.

function saveChanges(obj){
     var new_content = escape($F(obj.id+'_edit'));

     obj.innerHTML = ""Saving..."";
     cleanUp(obj, true);

     var success = function(t){editComplete(t, obj);}
     var failure = function(t){editFailed(t, obj);}

     var url = 'edit.php';
     var pars = 'id=' + obj.id + '&content=' + new_content;
     var myAjax = new Ajax.Request(url, {method:'post',
          postBody:pars, onSuccess:success, onFailure:failure});
 }

 function editComplete(t, obj){
     obj.innerHTML = t.responseText;
     showAsEditable(obj, true);
 }

 function editFailed(t, obj){
     obj.innerHTML = 'Sorry, the update failed.';
     cleanUp(obj);
 }

As you can see, we first grab in the contents of the textarea into the variable new_content. We then remove the editor, set the content of the original object to “Saving…” to show that an update is occurring, and make the Ajax POST.

If the Ajax fails, editFailed() sets the contents of the object to “Sorry, the update failed.” Admittedly, that’s not a very helpful way to handle the error but I have to limit the scope of this article somewhere. It might be a good idea to stow away the original contents of the object (obj.preUpdate = obj.innerHTML) for later retrieval before setting the content to “Saving…”. No one likes a failure – especially a messy one.

If the Ajax call is successful, the server-side script returns the edited content, which we then place back inside the object from editComplete, and tidy up.

Meanwhile, back at the server

The missing piece of the puzzle is the server-side script for committing the changes to your database. Obviously, any solution I provide here is not going to fit your particular application. For the purposes of getting a functional demo going, here’s what I have in PHP.

<?php
     $id = $_POST['id'];
     $content = $_POST['content'];
     echo htmlspecialchars($content);
 ?>

Not exactly rocket science is it? I’m just catching the content item from the POST and echoing it back. For your application to be useful, however, you’ll need to know exactly which record you should be updating. I’m passing in the ID of my <div>, which is not a fat lot of use. You can modify saveChanges() to post back whatever information your app needs to know in order to process the update.

You should also check the user’s credentials to make sure they have permission to edit whatever it is they’re editing. Basically the same rules apply as with any script in your application.

Limitations

There are a few bits and bobs that in an ideal world I would tidy up. The first is the error handling, as I’ve already mentioned. The second is that from an idealistic standpoint, I’d rather not be using innerHTML. However, the reality is that it’s presently the most efficient way of making large changes to the document. If you’re serving as XML, remember that you’ll need to replace these with proper DOM nodes.

It’s also important to note that it’s quite difficult to make something like this universally accessible. Whenever you start updating large chunks of a document based on user interaction, a lot of non-traditional devices don’t cope well. The benefit of this technique, though, is that if JavaScript is unavailable none of the functionality gets implemented at all – it fails silently. It is for this reason that this shouldn’t be used as a complete replacement for a traditional, universally accessible edit form. It’s a great time-saver for those with the ability to use it, but it’s no replacement.

314,Easy Ajax with Prototype,"There’s little more impressive on the web today than a appropriate touch of Ajax. Used well, Ajax brings a web interface much closer to the experience of a desktop app, and can turn a bear of an task into a pleasurable activity.

But it’s really hard, right? It involves all the nasty JavaScript that no one ever does often enough to get really good at, and the browser support is patchy, and urgh it’s just so much damn effort. Well, the good news is that – ta-da – it doesn’t have to be a headache. But man does it still look impressive. Here’s how to amaze your friends.

Introducing prototype.js

Prototype is a JavaScript framework by Sam Stephenson designed to help make developing dynamic web apps a whole lot easier. In basic terms, it’s a JavaScript file which you link into your page that then enables you to do cool stuff.

There’s loads of capability built in, a portion of which covers our beloved Ajax. The whole thing is freely distributable under an MIT-style license, so it’s good to go. What a nice man that Mr Stephenson is – friends, let us raise a hearty cup of mulled wine to his good name. Cheers! sluurrrrp.

First step is to download the latest Prototype and put it somewhere safe. I suggest underneath the Christmas tree.

Cutting to the chase

Before I go on and set up an example of how to use this, let’s just get to the crux. Here’s how Prototype enables you to make a simple Ajax call and dump the results back to the page:

var url = 'myscript.php';
var pars = 'foo=bar';
var target = 'output-div';	
var myAjax = new Ajax.Updater(target, url, {method: 'get', parameters: pars});

This snippet of JavaScript does a GET to myscript.php, with the parameter foo=bar, and when a result is returned, it places it inside the element with the ID output-div on your page.

Knocking up a basic example

So to get this show on the road, there are three files we need to set up in our site alongside prototype.js. Obviously we need a basic HTML page with prototype.js linked in. This is the page the user interacts with. Secondly, we need our own JavaScript file for the glue between the interface and the stuff Prototype is doing. Lastly, we need the page (a PHP script in my case) that the Ajax is going to make its call too.

So, to that basic HTML page for the user to interact with. Here’s one I found whilst out carol singing:

<!DOCTYPE html PUBLIC ""-//W3C//DTD XHTML 1.0 Strict//EN""
    ""http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"">
<html xmlns=""http://www.w3.org/1999/xhtml"" xml:lang=""en"" lang=""en"">
<head>
    <meta http-equiv=""Content-Type"" content=""text/html; charset=utf-8""/>
    <title>Easy Ajax</title>
    <script type=""text/javascript"" src=""prototype.js""></script>
    <script type=""text/javascript"" src=""ajax.js""></script>
</head> 
<body>
    <form method=""get"" action=""greeting.php"" id=""greeting-form"">
        <div>
            <label for=""greeting-name"">Enter your name:</label>
            <input id=""greeting-name"" type=""text"" />
            <input id=""greeting-submit"" type=""submit"" value=""Greet me!"" />
        </div>
        <div id=""greeting""></div>
    </form>
</body>
</html>

As you can see, I’ve linked in prototype.js, and also a file called ajax.js, which is where we’ll be putting our glue. (Careful where you leave your glue, kids.)

Our basic example is just going to take a name and then echo it back in the form of a seasonal greeting. There’s a form with an input field for a name, and crucially a DIV (greeting) for the result of our call. You’ll also notice that the form has a submit button – this is so that it can function as a regular form when no JavaScript is available. It’s important not to get carried away and forget the basics of accessibility.

Meanwhile, back at the server

So we need a script at the server which is going to take input from the Ajax call and return some output. This is normally where you’d hook into a database and do whatever transaction you need to before returning a result. To keep this as simple as possible, all this example here will do is take the name the user has given and add it to a greeting message. Not exactly Web 2-point-HoHoHo, but there you have it.

Here’s a quick PHP script – greeting.php – that Santa brought me early.

<?php
     $the_name = htmlspecialchars($_GET['greeting-name']);
     echo ""<p>Season's Greetings, $the_name!</p>"";
?>

You’ll perhaps want to do something a little more complex within your own projects. Just sayin’.

Gluing it all together

Inside our ajax.js file, we need to hook this all together. We’re going to take advantage of some of the handy listener routines and such that Prototype also makes available. The first task is to attach a listener to set the scene once the window has loaded. He’s how we attach an onload event to the window object and get it to call a function named init():

Event.observe(window, 'load', init, false);

Now we create our init() function to do our evil bidding. Its first job of the day is to hide the submit button for those with JavaScript enabled. After that, it attaches a listener to watch for the user typing in the name field.

function init(){
     $('greeting-submit').style.display = 'none';
     Event.observe('greeting-name', 'keyup', greet, false);
}

As you can see, this is going to make a call to a function called greet() onkeyup in the greeting-name field. That function looks like this:

function greet(){
     var url = 'greeting.php';
     var pars = 'greeting-name='+escape($F('greeting-name'));
     var target = 'greeting';
     var myAjax = new Ajax.Updater(target, url, {method: 'get', parameters: pars});
}

The key points to note here are that any user input needs to be escaped before putting into the parameters so that it’s URL-ready. The target is the ID of the element on the page (a DIV in our case) which will be the recipient of the output from the Ajax call.

That’s it

No, seriously. That’s everything. Try the example. Amaze your friends with your 1337 Ajax sk1llz.",2005,Drew McLellan,drewmclellan,2005-12-01T00:00:00+00:00,https://24ways.org/2005/easy-ajax-with-prototype/,code
326,Don't be eval(),"JavaScript is an interpreted language, and like so many of its peers it includes the all powerful eval() function. eval() takes a string and executes it as if it were regular JavaScript code. It’s incredibly powerful and incredibly easy to abuse in ways that make your code slower and harder to maintain. As a general rule, if you’re using eval() there’s probably something wrong with your design.

Common mistakes

Here’s the classic misuse of eval(). You have a JavaScript object, foo, and you want to access a property on it – but you don’t know the name of the property until runtime. Here’s how NOT to do it:

var property = 'bar';
var value = eval('foo.' + property);

Yes it will work, but every time that piece of code runs JavaScript will have to kick back in to interpreter mode, slowing down your app. It’s also dirt ugly.

Here’s the right way of doing the above:

var property = 'bar';
var value = foo[property];

In JavaScript, square brackets act as an alternative to lookups using a dot. The only difference is that square bracket syntax expects a string.

Security issues

In any programming language you should be extremely cautious of executing code from an untrusted source. The same is true for JavaScript – you should be extremely cautious of running eval() against any code that may have been tampered with – for example, strings taken from the page query string. Executing untrusted code can leave you vulnerable to cross-site scripting attacks.

What’s it good for?

Some programmers say that eval() is B.A.D. – Broken As Designed – and should be removed from the language. However, there are some places in which it can dramatically simplify your code. A great example is for use with XMLHttpRequest, a component of the set of tools more popularly known as Ajax. XMLHttpRequest lets you make a call back to the server from JavaScript without refreshing the whole page. A simple way of using this is to have the server return JavaScript code which is then passed to eval(). Here is a simple function for doing exactly that – it takes the URL to some JavaScript code (or a server-side script that produces JavaScript) and loads and executes that code using XMLHttpRequest and eval().

function evalRequest(url) {
     var xmlhttp = new XMLHttpRequest();
     xmlhttp.onreadystatechange = function() {
          if (xmlhttp.readyState==4 && xmlhttp.status==200) {
               eval(xmlhttp.responseText);
          }
     }
     xmlhttp.open(""GET"", url, true);
     xmlhttp.send(null);
 }

If you want this to work with Internet Explorer you’ll need to include this compatibility patch.",2005,Simon Willison,simonwillison,2005-12-07T00:00:00+00:00,https://24ways.org/2005/dont-be-eval/,code
320,DOM Scripting Your Way to Better Blockquotes,"Block quotes are great. I don’t mean they’re great for indenting content – that would be an abuse of the browser’s default styling. I mean they’re great for semantically marking up a chunk of text that is being quoted verbatim. They’re especially useful in blog posts. 

<blockquote>
     <p>Progressive Enhancement, as a label for a strategy for Web design, 
     was coined by Steven Champeon in a series of articles and presentations 
     for Webmonkey and the SxSW Interactive conference.</p>
 </blockquote>

Notice that you can’t just put the quoted text directly between the <blockquote> tags. In order for your markup to be valid, block quotes may only contain block-level elements such as paragraphs.

There is an optional cite attribute that you can place in the opening <blockquote> tag. This should contain a URL containing the original text you are quoting:

<blockquote cite=""http://en.wikipedia.org/wiki/Progressive_Enhancement"">
     <p>Progressive Enhancement, as a label for a strategy for Web design, 
     was coined by Steven Champeon in a series of articles and presentations 
     for Webmonkey and the SxSW Interactive conference.</p>
 </blockquote>

Great! Except… the default behavior in most browsers is to completely ignore the cite attribute. Even though it contains important and useful information, the URL in the cite attribute is hidden.

You could simply duplicate the information with a hyperlink at the end of the quoted text:

<blockquote cite=""http://en.wikipedia.org/wiki/Progressive_Enhancement"">
     <p>Progressive Enhancement, as a label for a strategy for Web design, 
     was coined by Steven Champeon in a series of articles and presentations 
     for Webmonkey and the SxSW Interactive conference.</p>
     <p class=""attribution"">
          <a href=""http://en.wikipedia.org/wiki/Progressive_Enhancement"">source</a>
     </p>
 </blockquote>

But somehow it feels wrong to have to write out the same URL twice every time you want to quote something. It could also get very tedious if you have a lot of quotes.

Well, “tedious” is no problem to a programming language, so why not use a sprinkling of DOM Scripting? Here’s a plan for generating an attribution link for every block quote with a cite attribute:


	Write a function called prepareBlockquotes.
	Begin by making sure the browser understands the methods you will be using.
	Get all the blockquote elements in the document.
	Start looping through each one.
	Get the value of the cite attribute.
	If the value is empty, continue on to the next iteration of the loop.
	Create a paragraph.
	Create a link.
	Give the paragraph a class of “attribution”.
	Give the link an href attribute with the value from the cite attribute.
	Place the text “source” inside the link.
	Place the link inside the paragraph.
	Place the paragraph inside the block quote.
	Close the for loop.
	Close the function.


Here’s how that translates to JavaScript:

function prepareBlockquotes() {
     if (!document.getElementsByTagName || !document.createElement || !document.appendChild) return;
     var quotes = document.getElementsByTagName(""blockquote"");
     for (var i=0; i<quotes.length; i++) {
          var source = quotes[i].getAttribute(""cite"");
          if (!source) continue;
          var para = document.createElement(""p"");
          var link = document.createElement(""a"");
          para.className = ""attribution"";
          link.setAttribute(""href"",source);
          link.appendChild(document.createTextNode(""source""));
          para.appendChild(link);
          quotes[i].appendChild(para);
     }
 }


Now all you need to do is trigger that function when the document has loaded:

window.onload = prepareBlockquotes;

Better yet, use Simon Willison’s handy addLoadEvent function to queue this function up with any others you might want to execute when the page loads.

That’s it. All you need to do is save this function in a JavaScript file and reference that file from the head of your document using <script> tags.

You can style the attribution link using CSS. It might look good aligned to the right with a smaller font size.

If you’re looking for something to do to keep you busy this Christmas, I’m sure that this function could be greatly improved. Here are a few ideas to get you started:


	Should the text inside the generated link be the URL itself?
	If the block quote has a title attribute, how would you take its value and use it as the text inside the generated link?
	Should the attribution paragraph be placed outside the block quote? If so, how would you that (remember, there is an insertBefore method but no insertAfter)?
	Can you think of other instances of useful information that’s locked away inside attributes? Access keys? Abbreviations?",2005,Jeremy Keith,jeremykeith,2005-12-05T00:00:00+00:00,https://24ways.org/2005/dom-scripting-your-way-to-better-blockquotes/,code
324,Debugging CSS with the DOM Inspector,"An Inspector Calls

The larger your site and your CSS becomes, the more likely that you will run into bizarre, inexplicable problems. Why does that heading have all that extra padding? Why is my text the wrong colour? Why does my navigation have a large moose dressed as Noel Coward on top of all the links? 

Perhaps you work in a collaborative environment, where developers and other designers are adding code? In which case, the likelihood of CSS strangeness is higher.

You need to debug. You need Firefox’s wise-guy know-it-all, the DOM Inspector. 

The DOM Inspector knows where everything is in your layout, and more importantly, what causes it to look the way it does. So without further ado, load up any css based site in your copy of Firefox (or Flock for that matter), and launch the DOM Inspector from the Tools menu.

The inspector uses two main panels – the left to show the DOM tree of the page, and the right to show you detail:



The Inspector will look at whatever site is in the front-most window or tab, but you can also use it without another window. Type in a URL at the top (A), press ‘Inspect’ (B) and a third panel appears at the bottom, with the browser view. I find this layout handier than looking at a window behind the DOM Inspector.

Step 1 – find your node!

Each element on your page – be it a HTML tag or a piece of text, is called a ‘node’ of the DOM tree. These nodes are all listed in the left hand panel, with any ID or CLASS attribute values next to them.  When you first look at a page, you won’t see all those yet. Nested HTML elements (such as a link inside a paragraph) have a reveal triangle next to their name, clicking this takes you one level further down. 

This can be fine for finding the node you want to look at, but there are easier ways. Say you have a complex rounded box technique that involves 6 nested DIVs? You’d soon get tired of clicking all those triangles to find the element you want to inspect. Click the top left icon © – “Find a node to inspect by clicking on it” and then select the area you want to inspect. Boom! All that drilling down the DOM tree has been done for you! Huzzah!

If you’re looking for an element that you know has an ID (such as <ul id=""navigation"">), or a specific HTML tag or attribute, click the binoculars icon (D) for “Finds a node to inspect by ID, tag or attribute” (You can also use Ctrl-F or Apple-F to do this if the DOM Inspector is the frontmost window) :



Type in the name and Bam! You’re there! Pressing F3 will take you to any other instances. Notice also, that when you click on a node in the inspector, it highlights where it is in the browser view with a flashing red border!

Now that we’ve found the troublesome node on the page, we can find out what’s up with it…

Step 2 – Debug that node!

Once the node is selected, we move over to the right hand panel. Choose ‘CSS Style Rules’ from the document menu (E), and all the CSS rules that apply to that node are revealed, in the order that they load:



You’ll notice that right at the top, there is a CSS file you might not recognise, with a file path beginning with “resource://”. This is the browsers default CSS, that creates the basic rendering. You can mostly ignore this, especially if use the star selector method of resetting default browser styles. 

Your style sheets come next. See how helpful it is? It even tells you the line number where to find the related CSS rules! If you use CSS shorthand, you’ll notice that the values are split up (e.g margin-left, margin-right etc.). 

Now that you can see all the style rules affecting that node, the rest is up to you! Happy debugging!",2005,Jon Hicks,jonhicks,2005-12-22T00:00:00+00:00,https://24ways.org/2005/debugging-css-with-the-dom-inspector/,process
332,CSS Layout Starting Points,"I build a lot of CSS layouts, some incredibly simple, others that cause sleepless nights and remind me of the torturous puzzle books that were given to me at Christmas by aunties concerned for my education. However, most of the time these layouts fit quite comfortably into one of a very few standard formats. For example:


	Liquid, multiple column with no footer
	Liquid, multiple column with footer
	Fixed width, centred


Rather than starting out with blank CSS and (X)HTML documents every time you need to build a layout, you can fairly quickly create a bunch of layout starting points, that will give you a solid basis for creating the rest of the design and mean that you don’t have to remember how a three column layout with a footer is best achieved every time you come across one! 

These starting points can be really basic, in fact that’s exactly what you want as the final design, the fonts, the colours and so on will be different every time. It’s just the main sections we want to be able to quickly get into place. For example, here is a basic starting point CSS and XHTML document for a fixed width, centred layout with a footer.

 <!DOCTYPE html PUBLIC ""-//W3C//DTD XHTML 1.0 Strict//EN""
     ""http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"">
<html xmlns=""http://www.w3.org/1999/xhtml"">
<head>
     <title>Fixed Width and Centred starting point document</title>
     <link rel=""stylesheet"" type=""text/css"" href=""fixed-width-centred.css"" />
     <meta http-equiv=""Content-Type"" content=""text/html; charset=utf-8"" />
</head>
<body>
<div id=""wrapper"">
     <div id=""side"">
          <div class=""inner"">
               <p>Sidebar content here</p>
          </div>
     </div>
     <div id=""content"">
          <div class=""inner"">
               <p>Your main content goes here.</p>
          </div>
     </div>
     <div id=""footer"">
          <div class=""inner"">
               <p>Ho Ho Ho!</p>
          </div>
     </div>
</div>
</body>
</html>

 body {
     text-align: center;
     min-width: 740px;
     padding: 0;
     margin: 0;
 }

 #wrapper {
     text-align: left;
     width: 740px;
     margin-left: auto;
     margin-right: auto;
     padding: 0;
 }

 #content {
     margin: 0 200px 0 0;
 }

 #content .inner {
     padding-top: 1px;
     margin: 0 10px 10px 10px;
 }

 #side {
     float: right;
     width: 180px;
     margin: 0;
 }

 #side .inner {
     padding-top: 1px;
     margin: 0 10px 10px 10px;
 }

 #footer {
     margin-top: 10px;
     clear: both;
 }

 #footer .inner {
     margin: 10px;
 }

9 times out of 10, after figuring out exactly what main elements I have in a layout, I can quickly grab the ‘one I prepared earlier’, mark-up the relevant sections within the ready-made divs, and from that point on, I only need to worry about the contents of those different areas. The actual layout is tried and tested, one that I know works well in different browsers and that is unlikely to throw me any nasty surprises later on. In addition, considering how the layout is going to work first prevents the problem of developing a layout, then realising you need to put a footer on it, and needing to redevelop the layout as the method you have chosen won’t work well with a footer.

While enjoying your mince pies and mulled wine during the ‘quiet time’ between Christmas and New Year, why not create some starting point layouts of your own? The css-discuss Wiki, CSS layouts section is a great place to find examples that you can try out and find your favourite method of creating the various layout types.",2005,Rachel Andrew,rachelandrew,2005-12-04T00:00:00+00:00,https://24ways.org/2005/css-layout-starting-points/,code
313,Centered Tabs with CSS,"Doug Bowman’s Sliding Doors is pretty much the de facto way to build tabbed navigation with CSS, and rightfully so – it is, as they say, rockin’ like Dokken. But since it relies heavily on floats for the positioning of its tabs, we’re constrained to either left- or right-hand navigation. But what if we need a bit more flexibility? What if we need to place our navigation in the center?

Styling the li as a floated block does give us a great deal of control over margin, padding, and other presentational styles. However, we should learn to love the inline box – with it, we can create a flexible, centered alternative to floated navigation lists.

Humble Beginnings

Do an extra shot of ‘nog, because you know what’s coming next. That’s right, a simple unordered list:

<div id=""navigation"">
     <ul>
          <li><a href=""#""><span>Home</span></a></li>
          <li><a href=""#""><span>About</span></a></li>
          <li><a href=""#""><span>Our Work</span></a></li>
          <li><a href=""#""><span>Products</span></a></li>
          <li class=""last""><a href=""#""><span>Contact Us</span></a></li>
     </ul>
</div>

If we were wedded to using floats to style our list, we could easily fix the width of our ul, and trick it out with some margin: 0 auto; love to center it accordingly. But this wouldn’t net us much flexibility: if we ever changed the number of navigation items, or if the user increased her browser’s font size, our design could easily break.

Instead of worrying about floats, let’s take the most basic approach possible: let’s turn our list items into inline elements, and simply use text-align to center them within the ul:

#navigation ul, #navigation ul li {
     list-style: none;
     margin: 0;
     padding: 0;
}

#navigation ul {
     text-align: center;
}

#navigation ul li {
     display: inline;
     margin-right: .75em;
}

#navigation ul li.last {
     margin-right: 0;
}

Our first step is sexy, no? Well, okay, not really – but it gives us a good starting point. We’ve tamed our list by removing its default styles, set the list items to display: inline, and centered the lot. Adding a background color to the links shows us exactly how the different elements are positioned.

Now the fun stuff.

Inline Elements, Padding, and You

So how do we give our links some dimensions? Well, as the CSS specification tells us, the height property isn’t an option for inline elements such as our anchors. However, what if we add some padding to them?

#navigation li a {
     padding: 5px 1em;
}

I just love leading questions. Things are looking good, but something’s amiss: as you can see, the padded anchors seem to be escaping their containing list.

Thankfully, it’s easy to get things back in line. Our anchors have 5 pixels of padding on their top and bottom edges, right? Well, by applying the same vertical padding to the list, our list will finally “contain” its child elements once again.

’Tis the Season for Tabbing

Now, we’re finally able to follow the “Sliding Doors” model, and tack on some graphics:

#navigation ul li a {
     background: url(""tab-right.gif"") no-repeat 100% 0;
     color: #06C;
     padding: 5px 0;
     text-decoration: none;
}

#navigation ul li a span {
     background: url(""tab-left.gif"") no-repeat;
     padding: 5px 1em;
}

#navigation ul li a:hover span {
     color: #69C;
     text-decoration: underline;
}

Finally, our navigation’s looking appropriately sexy. By placing an equal amount of padding on the top and bottom of the ul, our tabs are properly “contained”, and we can subsequently style the links within them.



But what if we want them to bleed over the bottom-most border? Easy: we can simply decrease the bottom padding on the list by one pixel, like so.

A Special Note for Special Browsers

The Mac IE5 users in the audience are likely hopping up and down by now: as they’ve discovered, our centered navigation behaves rather annoyingly in their browser. As Philippe Wittenbergh has reported, Mac IE5 is known to create “phantom links” in a block-level element when text-align is set to any value but the default value of left. Thankfully, Philippe has documented a workaround that gets that [censored] venerable browser to behave. Simply place the following code into your CSS, and the links will be restored to their appropriate width:

/**//*/
#navigation ul li a {
     display: inline-block;
     white-space: nowrap;
     width: 1px;
}
/**/

IE for Windows, however, displays an extra kind of crazy. The padding I’ve placed on my anchors is offsetting the spans that contain the left curve of my tabs; thankfully, these shenanigans are easily straightened out:

/**/
* html #navigation ul li a {
     padding: 0;
}
/**/

And with that, we’re finally finished.

All set.

And that’s it. With your centered navigation in hand, you can finally enjoy those holiday toddies and uncomfortable conversations with your skeevy Uncle Eustace.",2005,Ethan Marcotte,ethanmarcotte,2005-12-08T00:00:00+00:00,https://24ways.org/2005/centered-tabs-with-css/,code
329,Broader Border Corners,"A note from the editors:  Since this article was written the CSS border-radius property has become widely supported in browsers. It should be preferred to this image technique.
                
                
                      
                A quick and easy recipe for turning those single-pixel borders that the kids love so much into  into something a little less right-angled.

Here’s the principle: We have a box with a one-pixel wide border around it. Inside that box is another box that has a little rounded-corner background image sitting snugly in one of its corners. The inner-box is then nudged out a bit so that it’s actually sitting on top of the outer box. If it’s all done properly, that little background image can mask the hard right angle of the default border of the outer-box, giving the impression that it actually has a rounded corner.

Take An Image, Finely Chopped



Add A Sprinkle of Markup

<div id=""content"">
    <p>Lorem ipsum etc. etc. etc.</p>
</div>

Throw In A Dollop of CSS

#content { 
     border: 1px solid #c03;
}

#content p {
     background: url(corner.gif) top left no-repeat;
     position: relative;
     left: -1px;
     top: -1px;
     padding: 1em;
     margin: 0;
}

Bubblin’ Hot


	The content div has a one-pixel wide red border around it.
	The paragraph is given a single instance of the background image, created to look like a one-pixel wide arc.
	The paragraph is shunted outside of the box – back one pixel and up one pixel – so that it is sitting over the div’s border. The white area of the image covers up that part of the border’s corner, and the arc meets up with the top and left border.
	Because, in this example, we’re applying a background image to a paragraph, its top margin needs to be zeroed so that it starts at the top of its container.


Et voilà. Bon appétit.

Extra Toppings


	If you want to apply a curve to each one of the corners and you run out of meaningful markup to hook the background images on to, throw some spans or divs in the mix (there’s nothing wrong with this if that’s the effect you truly want – they don’t hurt anybody) or use some nifty DOM Scripting to put the scaffolding in for you.
	Note that if you’ve got more than one of these relative corners, you will need to compensate for the starting position of each box which is nested in an already nudged parent.
	You’re not limited to one pixel wide, rounded corners – the same principles apply to thicker borders, or corners with different shapes.",2005,Patrick Griffiths,patrickgriffiths,2005-12-14T00:00:00+00:00,https://24ways.org/2005/broader-border-corners/,design
319,Avoiding CSS Hacks for Internet Explorer,"Back in October, IEBlog issued a call to action, asking developers to clean up their CSS hacks for IE7 testing. Needless to say, a lot of hubbub ensued… both on IEBlog and elsewhere. My contribution to all of the noise was to suggest that developers review their code and use good CSS hacks. But what makes a good hack?

Tantek Çelik, the Godfather of CSS hacks, gave us the answer by explaining how CSS hacks should be designed. In short, they should (1) be valid, (2) target only old/frozen/abandoned user-agents/browsers, and (3) be ugly. Tantek also went on to explain that using a feature of CSS is not a hack.

Now, I’m not a frequent user of CSS hacks, but Tantek’s post made sense to me. In particular, I felt it gave developers direction on how we should be coding to accommodate that sometimes troublesome browser, Internet Explorer. But what I’ve found, through my work with other developers, is that there is still much confusion over the use of CSS hacks and IE. Using examples from the code I’ve seen recently, allow me to demonstrate how to clean up some IE-specific CSS hacks.

The two hacks that I’ve found most often in the code I’ve seen and worked with are the star html bug and the underscore hack. We know these are both IE-specific by checking Kevin Smith’s CSS Filters chart. Let’s look at each of these hacks and see how we can replace them with the same CSS feature-based solution.

The star html bug

This hack violates Tantek’s second rule as it targets current (and future) UAs. I’ve seen this both as a stand alone rule, as well as an override to some other rule in a style sheet. Here are some code samples:

* html div#header {margin-top:-3px;}
.promo h3 {min-height:21px;}
* html .promo h3 {height:21px;}

The underscore hack

This hack violates Tantek’s first two rules: it’s invalid (according to the W3C CSS Validator) and it targets current UAs. Here’s an example:

ol {padding:0; _padding-left:5px;}

Using child selectors

We can use the child selector to replace both the star html bug and underscore hack. Here’s how:

 Write rules with selectors that would be successfully applied to all browsers. This may mean starting with no declarations in your rule!

div#header {}
.promo h3 {}
ol {padding:0;}

 
To these rules, add the IE-specific declarations.

div#header {margin-top:-3px;}
.promo h3 {height:21px;}
ol {padding:0 0 0 5px;}

 
After each rule, add a second rule. The selector of the second rule must use a child selector. In this new rule, correct any IE-specific declarations previously made.

div#header {margin-top:-3px;}
body > div#header {margin-top:0;}

.promo h3 {height:21px;}
.promo > h3 {height:auto; min-height:21px;}

ol {padding:0 0 0 5px;}
html > body ol {padding:0;}

 

Voilà – no more hacks! There are a few caveats to this that I won’t go into… but assuming you’re operating in strict mode and barring any really complicated stuff you’re doing in your code, your CSS will still render perfectly across browsers. And while this may make your CSS slightly heftier in size, it should future-proof it for IE7 (or so I hope). Happy holidays!",2005,Kimberly Blessing,kimberlyblessing,2005-12-17T00:00:00+00:00,https://24ways.org/2005/avoiding-css-hacks-for-internet-explorer/,code
318,Auto-Selecting Navigation,"In the article Centered Tabs with CSS Ethan laid out a tabbed navigation system which can be centred on the page. A frequent requirement for any tab-based navigation is to be able to visually represent the currently selected tab in some way.

If you’re using a server-side language such as PHP, it’s quite easy to write something like class=""selected"" into your markup, but it can be even simpler than that.

Let’s take the navigation div from Ethan’s article as an example.

<div id=""navigation"">
     <ul>
          <li><a href=""#""><span>Home</span></a></li>
          <li><a href=""#""><span>About</span></a></li>
          <li><a href=""#""><span>Our Work</span></a></li>
          <li><a href=""#""><span>Products</span></a></li>
          <li class=""last""><a href=""#""><span>Contact Us</span></a></li>
     </ul>
 </div>

As you can see we have a standard unordered list which is then styled with CSS to look like tabs. By giving each tab a class which describes it’s logical section of the site, if we were to then apply a class to the body tag of each page showing the same, we could write a clever CSS selector to highlight the correct tab on any given page. 

Sound complicated? Well, it’s not a trivial concept, but actually applying it is dead simple.

Modifying the markup

First thing is to place a class name on each li in the list:

<div id=""navigation"">
     <ul>
          <li class=""home""><a href=""#""><span>Home</span></a></li>
          <li class=""about""><a href=""#""><span>About</span></a></li>
          <li class=""work""><a href=""#""><span>Our Work</span></a></li>
          <li class=""products""><a href=""#""><span>Products</span></a></li>
          <li class=""last contact""><a href=""#""><span>Contact Us</span></a></li>
     </ul>
 </div>

Then, on each page of your site, apply the a matching class to the body tag to indicate which section of the site that page is in. For example, on your About page:

<body class=""about"">...</body>

Writing the CSS selector

You can now write a single CSS rule to match the selected tab on any given page. The logic is that you want to match the ‘about’ tab on the ‘about’ page and the ‘products’ tab on the ‘products’ page, so the selector looks like this:

body.home #navigation li.home,
 body.about #navigation li.about,
 body.work #navigation li.work,
 body.products #navigation li.products,
 body.contact #navigation li.contact{
      ... whatever styles you need to show the tab selected ...
 } 

So all you need to do when you create a new page in your site is to apply a class to the body tag to say which section it’s in. The CSS will do the rest for you – without any server-side help.",2005,Drew McLellan,drewmclellan,2005-12-10T00:00:00+00:00,https://24ways.org/2005/auto-selecting-navigation/,code
330,An Explanation of Ems,"Ems are so-called because they are thought to approximate the size of an uppercase letter M (and so are pronounced emm), although 1em is actually significantly larger than this. The typographer Robert Bringhurst describes the em thus:


	The em is a sliding measure. One em is a distance equal to the type size. In 6 point type, an em is 6 points; in 12 point type an em is 12 points and in 60 point type an em is 60 points. Thus a one em space is proportionately the same in any size.


To illustrate this principle in terms of CSS, consider these styles:

#box1 {
     font-size: 12px;
     width: 1em;
     height: 1em;
     border:1px solid black;
}

#box2 {
     font-size: 60px;
     width: 1em;
     height: 1em;
     border: 1px solid black;
}

These styles will render like:

 M

and

 M

Note that both boxes have a height and width of 1em but because they have different font sizes, one box is bigger than the other. Box 1 has a font-size of 12px so its width and height is also 12px; similarly the text of box 2 is set to 60px and so its width and height are also 60px.",2005,Richard Rutter,richardrutter,2005-12-02T00:00:00+00:00,https://24ways.org/2005/an-explanation-of-ems/,design
