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?

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.

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
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.

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
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
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.

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.
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.
The last item is different
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"");

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
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 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
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.
Figure 2: Ligature, Loop & Stem, from Scott Boms & Luke Dorny
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?
Figure 7: Jessica Hische‘s beautiful Daily Drop Cap
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
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.
Check out the demo and get the source code on GitHub.
query->results->results;
/* YouTube output */
$youtube = '
';
foreach($results[0]->item as $r){
$cleanHTML = undoYouTubeMarkupCrimes($r->description);
$youtube .= '
'.$cleanHTML.'
';
}
$youtube .= '
';
/* Flickr output */
$flickr = '
';
foreach($results[1]->photo as $r){
$flickr .= '
',$cleaner);
return $cleaner;
}
?>
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):
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):
query->results->Result);
echo join('
',$topics);
?>
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
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

Me: What’s wrong with 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:
Please wait while we do what we do best.
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
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:
Found this little cutie on a walk in New Zealand!
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:
White water rafting in Queenstown
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!

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.
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 tag. To work around this, wrap your entire email with a 100% width table and give that a background color.
Your email code goes here.
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
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 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 and 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 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:
your height sensitive text
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:
this is a link
Next, add a redundant span inside the a tag.
this is a link
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.
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
