What It Takes to Build a Website |
In 1994 we lost Kurt Cobain and got the world wide web as a weird consolation prize. In the years that followed, if you’d asked me if I knew how to build a website I’d have said yes, I know HTML, so I know how to build a website. If you’d then asked me what it takes to build a website, I’d have had to admit that HTML would hardly feature.
Among the design nerdery and dev geekery it’s easy to think that the nuts and bolts of building a page just need to be multiplied up and Ta-da! There’s your website. That can certainly be true with weekend projects and hackery for fun. It works for throwing something together on GitHub or experimenting with ideas on your personal site. But what about working professionally on client projects?
The web is important, so we need to build it right.
It’s 2015 – your job involves people paying you money for building websites. What does it take to build a website and to do it right? What practices should we adopt to make really great, successful and professional web projects in 2015? I put that question to some friends and 24 ways authors to see what they thought.
Getting the tech right
Inevitably, it all starts with the technology. We work in a technical medium, after all. From Notepad and WinFTP through to continuous integration and deployment – how do you build sites?
Create a stable development environment
There’s little more likely to send a web developer into a wild panic and a client into a wild rage than making a new site live and things just not working. That’s why it’s important to have realistic development and staging environments that mimic the live server as closely as possible.
Are you in the habit of developing new sites right on the client’s server? Or maybe in a subfolder on your local machine? It’s time to reconsider.
Charlie Perrins writes:
Don’t work on a live server – this feels like one of those gear-changing moments for a developer’s growth. Build something that works just as well locally on your own machine as it does on a live server, and capture the differences in the code between the local and live version in a single config file. Ultimately, if you can get all the differences between environments down to a config level then you’ll be in a really good position to automate the deployment process at some point in the future.
Anything that creates a significant difference between the development and the live environments has the potential to cause problems you won’t know about until the site goes live – and at that point the problems are very public and very embarrassing, not to mention unprofessional.
A reasonable solution is to use a tool like MAMP PRO which enables you to set up an individual local website for each project you work on. Importantly, individual sites give you both consistency of paths between development and live, but also the ability to configure server options (like PHP versions and configuration, for example) to match the live site.
Better yet is to use a virtual machine, managed with a tool such as Vagrant. If you’re interested in learning more about that, we have an article on that subject later in the series.
Use source control
Trent Walton writes:
We use source control, and it’s become the centerpiece for how we handle collaboration, enhancements, and issues. It drives our process.
I’m hoping by now that you’re either using source control for all your work, or feeling a nagging guilt that you should be. Be it Git, Mercurial, Subversion (name your poison), a revision control system enables you to keep track of changes, revert anything that breaks, and keep rolling backups of your project.
The benefits only start there, and Charlie Perrins recommends using source control “not just as a personal backup of your code, but as a way to play nicely with other developers.“
Noting the benefits when collaborating with other developers, he adds:
Graduating from being the sole architect of your codebase to contributing to a shared codebase is a huge leap for a developer. Perhaps a practical way for people who tend to work on their own to do that would be to submit a pull request or a patch to an open source project or plugin.”
Richard Rutter of Clearleft sees clear advantages for the client, too. He recommends using source control “preferably in some sort of collaborative environment that you can open up or hand over to the client” – a feature found with hosted services such as GitHub.
If you’d like to hone your Git skills, Emma Jane Westby wrote Git for Grown-ups in last year’s 24 ways.
Don’t repeat, automate!
Tim Kadlec is a big proponent of automating your build process:
I’ve been hammering that home to every client I’ve had this year. It’s amazing how many companies don’t really have a formal build/deployment process in place. So many issues on the web (performance, accessibility, etc.) can be greatly improved just by having a layer of automation involved.
For example, graphic editing software spits out ridiculously bloated images. Very frequently, that’s what ends up getting put on a site. If you have a build process, you can have the compression automated and start seeing immediate gains for no effort. On a recent project, they were able to shave around 1.5MB from their site weight simply by automating compression.
Once you have your code in source control, some of that automation can be made easier. Brian Suda writes:
We have a few bash scripts that run on git commit: they compile the less, jslint and remove white-space, basically the 3 Cs, Compress, Concatenate, Combine. This is now part of our workflow without even realising it.
One great way to get started with a build process is to use a tool like Grunt, and a great way to get started with Grunt is to read Chris Coyier’s Grunt for People Who Think Things Like Grunt are Weird and Hard.
Tim reinforces:
Issues like [image compression] — or simple accessibility issues like alt tags on images — should never be able to hit a live server. If you can detect it, you can automate it. And if you can automate it, you can free up time for designers and developers to focus on more challenging — and interesting — problems.
A clear call to arms to tighten up and formalise development and deployment practices. The less that has to be done manually or is susceptible to change, the less that can go wrong when a site is built and deployed. Any procedures that are automated are no longer dependant on a single person’s knowledge, making it easier to build your team or just cope when someone important is out of the office or leaves.
If you’re interested in kicking the FTP habit and automating your site deployments, we have an article later in the series just for you.
Build systems, not sites
One big theme arising this year was that of building websites as systems, not as individual pages.
Brad Frost:
For me, teams making websites in 2015 shouldn’t be working on just-another-redesign redesign. People are realizing that in order to make stable, future-friendly, scalable, extensible web experiences they’re going to need to think more systematically. That means crafting deliberate and thoughtful design systems. That means establishing front-end style guides. That means killing the out-dated, siloed, assembly-line waterfall process and getting cross-disciplinary teams working together in meaningful ways. That means treating development as design. That means treating performance as design. That means taking the time out of the day to establish the big picture, rather than aimlessly crawling along quarter by quarter.
Designer and developer Jina Bolton also advocates the use of style guides, and recommends making the guide a project deliverable:
Consider adding on a style guide/UI library to your project as a deliverable for maintainability and thinking through all UI elements and components.
Val Head agrees: “build and maintain a style guide for each project” she wrote. On the subject of approaching a redesign, she added:
A UI inventory goes a long way to helping get your head around what a design system needs in the early stages of a redesign project.
So what about that old chestnut, responsive web design? Should we be making sites responsive by default? How about mobile first?
Richard Rutter:
Think mobile first unless you have a very good reason not to. Remember to take the client with you on this principle, otherwise it won’t work as a convincing piece of design.
Trent Walton adds:
The more you can test and sort of skew your perception for what is typical on the web, the better. 4k displays hooked up to 100Mbps connections can make one extremely unsympathetic.
The value of testing with real devices is something Ruth John appreciates. She wrote:
I still have my own small device lab at home, even though I work permanently for a well-established company (which has a LOT of devices at its disposal) – it just means I can get a good overview of how things are looking during development.
And speaking of systems, Mark Norman Francis recommends the use of measuring tools to aid the design process; “[U]se analytics and make decisions from actual data” he suggests, rather than relying totally on intuition.
Tim Kadlec adds a word on performance planning:
I think having a performance budget in place should now be a given on any project. We’ve proven pretty conclusively through a hundred and one case studies that performance matters. And over the last year or so, we’ve really seen a lot of great tools emerge to help track and enforce performance budgets. There’s not really a good excuse for not using one any more.
It’s clear that in the four years since Ethan Marcotte’s Responsive Web Design article the diversity of screen sizes, network connection speeds and input methods has only increased. New web projects should presume visitors will be using anything from a watch up to a big screen desktop display, and from being offline, through to GPRS, 3G and fast broadband.
Will it take more time to design and build for those constraints? Yes, it most likely will. If Internet Explorer is brave enough to ask to be your default browser, you can be brave enough to tell your client they need to build responsively.
Working collaboratively
A big part of delivering a successful website project is how we work together, both as a design team and a wider project team with the client.
Val Head recommends an open line of communication:
Keep conversations going. With clients, with teammates. Talking is so important with the way we work now. A good team conversation place, like Slack, is slowly becoming invaluable for me too.
Ruth John agrees:
We’ve recently opened up our lines of communication by using Slack. It has transformed the way we work. We’re easily more productive and collaborative on projects, as well as making it a lot easier for us all to work remotely (including freelancers).
She goes on to point out how tools can be combined to ease team communication without adding further complications:
We have a private GitHub organisation (which everyone who works with us is granted access to), which not only holds all our project code but also a team wiki. This has lots of information to get you set up within the team, as well as coding guidelines and best practices and other admin info, like contact numbers/emails for the team.
Small-A agile is also the theme of the day, with Mark Norman Francis suggesting an approach of “small iterations with constant feedback around individual features, not spec-it-all-first”. He also encourages you to review as you go, at each stage of the project:
Always reflect on what went well and what went badly, and how you can learn from that, even if not Doing Agile™. Ultimately “best practices” should come from learning lessons (both good and bad).
Richard Rutter echoes this, warning against working in isolation from the client for too long:
Avoid big reveals. Your engagement with the client should be participatory. In business no one likes surprises.
This experience rings true for Ruth John who recommends involving real users in the feedback loop, not just the client:
We also try and get feedback on what we’re building as soon and as often as we can with our stakeholders/clients and real users.
We should also remember that our role is to serve the client’s needs, not just bill them for whatever we can. Brian Suda adds:
Don’t sell clients on things they don’t need. We can spout a lot of jargon and scare clients into thinking you are a god. We can do things few can now, but you can’t rip people off because they are unknowledgeable.
But do clients know what they’re getting, even when they see it? Trent Walton has an interesting take:
We focus on prototypes over image-based comps at all costs, especially when meetings are involved. It’s much easier to assess a prototype, and too often with image-based comps, discussions devolve into how something might feel when actually live, or how a layout could change to fit a given viewport.
Val Head also likes to get work into the browser:
Sketch design ideas with any software you like, but get to the browser as soon as possible.
Beyond your immediate team, Emma Jane Westby has advice for looking further afield:
Invest time into building relationships within your (technical) community. You never know when you might be able to lend a hand; or benefit from someone who’s able to lend theirs.
And when things don’t go according to plan, Brian Suda has the following advice:
If something doesn’t work out, be professional and don’t burn bridges. It will always come back to you.
The best work comes from working collaboratively, not just as a team within an agency or department, but with the client and stakeholders too. If doing your job and chucking it over the fence ever worked, it certainly doesn’t fly any more. You can work in isolation, but doing really great work requires collaboration.
The business end
When you’re building sites professionally, every team member has to think about the business aspects. Estimating time, setting billing rates, and establishing deliverables are all part of the job.
In 2008, Andrew Clarke gave us the Contract Killer sample contract we could use to establish a working agreement for a web design project. Richard Rutter agrees that contracts are still an essential part of business:
They are there for both parties’ protection. Make sure you know what will happen if you decide you don’t want to work with the client any more (it happens) and, of course, what circumstances mean they can stop taking your services.
Having a contract is one thing, but does it adequately protect both you and the client? Emma Jane Westby adds:
Find a good IP lawyer/legal counsel. I routinely had an IP lawyer read all of my contracts to find loopholes I wouldn’t have noticed. I didn’t always change the contract, but at least I knew what might come back to bite me.
So, you have a contract in place, and know what the project is. Brian Suda recommends keeping track of time and making sure you bill fairly for the hours the project costs you:
If I go to a meeting and they are 15 minutes late, the billing clock has already started. They can’t expect me to be in the 1h meeting and not bill for the extra 15–30 minutes they wasted. It goes both ways too. You need to do your best to respect their deadlines and time frame – this is always hard to get right.
As ever, it’s good business to do good business. Perhaps we can at last shed the old image of web designers being snowboarding layabouts and demonstrate to clients that we care as much about conducting professional business as they do.
Time to review
It’s a lot to take in. Some of these ideas and practices will be familiar, others new and yet to be evaluated. The web moves at a fast pace, and we need to be constantly reexamining our tools, techniques and working practices. The most important thing is not to blindly adopt any and all suggestions, but to carefully look at what the benefits might be and decide how they apply to your work.
Could you benefit from more formalised development and deployment procedures? Would your design projects run more smoothly and have a longer maintainable life if you approached the solution as a componentised system rather than a series of pages? Are your teams structured in a way that enables the most fluid communication, or are there changes you could make? Are your billing procedures and business agreements serving you and your clients in the best way possible?
The new year is a good time to look at your working practices and see what can be improved, and maybe this time next year you’ll look back and think “thank goodness we don’t work like that any more”. |

Making Sites More Responsive, Responsibly |
With digital projects we’re used to shifting our thinking to align with our target audience. We may undertake research, create personas, identify key tasks, or observe usage patterns, with our findings helping to refine our ongoing creations. A product’s overall experience can make or break its success, and when it comes to defining these experiences our development choices play a huge role alongside more traditional user-focused activities.
The popularisation of responsive web design is a great example of how we are able to shape the web’s direction through using technology to provide better experiences. If we think back to the move from table-based layouts to CSS, initially our clients often didn’t know or care about the difference in these approaches, but we did. Responsive design was similar in this respect – momentum grew through the web industry choosing to use an approach that we felt would give a better experience, and which was more future-friendly.
We tend to think of responsive design as a means of displaying content appropriately across a range of devices, but the technology and our implementation of it can facilitate much more. A responsive layout not only helps your content work when the newest smartphone comes out, but it also ensures your layout suitably adapts if a visually impaired user drastically changes the size of the text.
The 24 ways site at 400% on a Retina MacBook Pro displays a layout more typically used for small screens.
When we think more broadly, we realise that our technical choices and approaches to implementation can have knock-on effects for the greater good, and beyond our initial target audiences. We can make our experiences more responsive to people’s needs, enhancing their usability and accessibility along the way.
Being responsibly responsive
Of course, when we think about being more responsive, there’s a fine line between creating useful functionality and becoming intrusive and overly complex. In the excellent Responsible Responsive Design, Scott Jehl states that:
A responsible responsive design equally considers the following throughout a project:
Usability: The way a website’s user interface is presented to the user, and how that UI responds to browsing conditions and user interactions.
Access: The ability for users of all devices, browsers, and assistive technologies to access and understand a site’s features and content.
Sustainability: The ability for the technology driving a site or application to work for devices that exist today and to continue to be usable and accessible to users, devices, and browsers in the future.
Performance: The speed at which a site’s features and content are perceived to be delivered to the user and the efficiency with which they operate within the user interface.
Scott’s book covers these ideas in a lot more detail than I’ll be able to here (put it on your Christmas list if it’s not there already), but for now let’s think a bit more about our roles as digital creators and the power this gives us.
Our choices around technology and the decisions we have to make can be extremely wide-ranging. Solutions will vary hugely depending on the needs of each project, though we can further explore the concept of making our creations more responsive through the use of humble web technologies.
The power of the web
We all know that under the HTML5 umbrella are some great new capabilities, including a number of JavaScript APIs such as geolocation, web audio, the file API and many more. We often use these to enhance the functionality of our sites and apps, to add in new features, or to facilitate device-specific interactions.
You’ll have seen articles with flashy titles such as “Top 5 JavaScript APIs You’ve Never Heard Of!”, which you’ll probably read, think “That’s quite cool”, yet never use in any real work.
There is great potential for technologies like these to be misused, but there are also great prospects for them to be used well to enhance experiences. Let’s have a look at a few examples you may not have considered.
Offline first
When we make websites, many of us follow a process which involves user stories – standardised snippets of context explaining who needs what, and why.
“As a student I want to pay online for my course so I don’t have to visit the college in person.”
“As a retailer I want to generate unique product codes so I can manage my stock.”
We very often focus heavily on what needs doing, but may not consider carefully how it will be done. As in Scott’s list, accessibility is extremely important, not only in terms of providing a great experience to users of assistive technologies, but also to make your creation more accessible in the general sense – including under different conditions.
Offline first is yet another ‘first’ methodology (my personal favourite being ‘tea first’), which encourages us to develop so that connectivity itself is an enhancement – letting users continue with tasks even when they’re offline. Despite the rapid growth in public Wi-Fi, if we consider data costs and connectivity in developing countries, our travel habits with planes, underground trains and roaming (or simply if you live in the UK’s signal-barren East Anglian wilderness as I do), then you’ll realise that connectivity isn’t as ubiquitous as our internet-addled brains would make us believe. Take a scenario that I’m sure we’re all familiar with – the digital conference. Your venue may be in a city served by high-speed networks, but after overloading capacity with a full house of hashtag-hungry attendees, each carrying several devices, then everyone’s likely to be offline after all. Wouldn’t it be better if we could do something like this instead?
Someone visits our conference website.
On this initial run, some assets may be cached for future use: the conference schedule, the site’s CSS, photos of the speakers.
When the attendee revisits the site on the day, the page shell loads up from the cache.
If we have cached content (our session timetable, speaker photos or anything else), we can load it directly from the cache. We might then try to update this, or get some new content from the internet, but the conference attendee already has a base experience to use.
If we don’t have something cached already, then we can try grabbing it online.
If for any reason our requests for new content fail (we’re offline), then we can display a pre-cached error message from the initial load, perhaps providing our users with alternative suggestions from what is cached.
There are a number of ways we can make something like this, including using the application cache (AppCache) if you’re that way inclined. However, you may want to look into service workers instead. There are also some great resources on Offline First! if you’d like to find out more about this.
Building in offline functionality isn’t necessarily about starting offline first, and it’s also perfectly possible to retrofit sites and apps to catch offline scenarios, but this kind of graceful degradation can end up being more complex than if we’d considered it from the start. By treating connectivity as an enhancement, we can improve the experience and provide better performance than we can when waiting to counter failures. Our websites can respond to connectivity and usage scenarios, on top of adapting how we present our content. Thinking in this way can enhance each point in Scott’s criteria.
As I mentioned, this isn’t necessarily the kind of development choice that our clients will ask us for, but it’s one we may decide is simply the right way to build based on our project, enhancing the experience we provide to people, and making it more responsive to their situation.
Even more accessible
We’ve looked at accessibility in terms of broadening when we can interact with a website, but what about how? Our user stories and personas are often of limited use. We refer in very general terms to students, retailers, and sometimes just users. What if we have a student whose needs are very different from another student? Can we make our sites even more usable and accessible through our development choices?
Again using JavaScript to illustrate this concept, we can do a lot more with the ways people interact with our websites, and with the feedback we provide, than simply accepting keyboard, mouse and touch inputs and displaying output on a screen.
Input
Ambient light detection is one of those features that looks great in simple demos, but which we struggle to put to practical use. It’s not new – many satnav systems automatically change the contrast for driving at night or in tunnels, and our laptops may alter the screen brightness or keyboard backlighting to better adapt to our surroundings. Using web technologies we can adapt our presentation to be better suited to ambient light levels.
If our device has an appropriate light sensor and runs a browser that supports the API, we can grab the ambient light in units using ambient light events, in JavaScript. We may then change our presentation based on different bandings, perhaps like this:
window.addEventListener('devicelight', function(e) {
var lux = e.value;
if (lux < 50) {
//Change things for dim light
}
if (lux >= 50 && lux <= 10000) {
//Change things for normal light
}
if (lux > 10000) {
//Change things for bright light
}
});
Live demo (requires light sensor and supported browser).
Soon we may also be able to do such detection through CSS, with light-level being cited in the Media Queries Level 4 specification. If that becomes the case, it’ll probably look something like this:
@media (light-level: dim) {
/*Change things for dim light*/
}
@media (light-level: normal) {
/*Change things for normal light*/
}
@media (light-level: washed) {
/*Change things for bright light*/
}
While we may be quick to dismiss this kind of detection as being a gimmick, it’s important to consider that apps such as Light Detector, listed on Apple’s accessibility page, provide important context around exactly this functionality.
“If you are blind, Light Detector helps you to be more independent in many daily activities. At home, point your iPhone towards the ceiling to understand where the light fixtures are and whether they are switched on. In a room, move the device along the wall to check if there is a window and where it is. You can find out whether the shades are drawn by moving the device up and down.”
everywaretechnologies.com/apps/lightdetector
Input can be about so much more than what we enter through keyboards. Both an ever increasing amount of available sensors and more APIs being supported by the major browsers will allow us to cater for more scenarios and respond to them accordingly. This can be as complex or simple as you need; for instance, while x-webkit-speech has been deprecated, the web speech API is available for a number of browsers, and research into sign language detection is also being performed by organisations such as Microsoft.
Output
Web technologies give us some great enhancements around input, allowing us to adapt our experiences accordingly. They also provide us with some nice ways to provide feedback to users.
When we play video games, many of our modern consoles come with the ability to have rumble effects on our controller pads. These are a great example of an enhancement, as they provide a level of feedback that is entirely optional, but which can give a great deal of extra information to the player in the right circumstances, and broaden the scope of our comprehension beyond what we’re seeing and hearing.
Haptic feedback is possible on the web as well. We could use this in any number of responsible applications, such as alerting a user to changes or using different patterns as a communication mechanism. If you find yourself in a pickle, here’s how to print out SOS in Morse code through the vibration API. The following code indicates the length of vibration in milliseconds, interspersed by pauses in milliseconds.
navigator.vibrate([100, 300, 100, 300, 100, 300, 600, 300, 600, 300, 600, 300, 100, 300, 100, 300, 100]);
Live demo (requires supported browser)
With great power…
What you’ve no doubt come to realise by now is that these are just more examples of progressive enhancement, whose inclusion will provide a better experience if the capabilities are available, but which we should not rely on. This idea isn’t new, but the most important thing to remember, and what I would like you to take away from this article, is that it is up to us to decide to include these kind of approaches within our projects – if we don’t root for them, they probably won’t happen. This is where our professional responsibility comes in.
We won’t necessarily be asked to implement solutions for the scenarios above, but they illustrate how we can help to push the boundaries of experiences. Maybe we’ll have to switch our thinking about how we build, but we can create more usable products for a diverse range of people and usage scenarios through the choices we make around technology. Let’s stop thinking simply in terms of features inside a narrow view of our target users, and work out how we can extend these to cater for a wider set of situations.
When you plan your next digital project, consider the power of the web and the enhancements we can use, and try to make your projects even more responsive and responsible. |

Dealing with Emergencies in Git |
The stockings were hung by the chimney with care,
In hopes that version control soon would be there.
This summer I moved to the UK with my partner, and the onslaught of the Christmas holiday season began around the end of October (October!). It does mean that I’ve had more than a fair amount of time to come up with horrible Git analogies for this article. Analogies, metaphors, and comparisons help the learner hook into existing mental models about how a system works. They only help, however, if the learner has enough familiarity with the topic at hand to make the connection between the old and new information.
Let’s start by painting an updated version of Clement Clarke Moore’s Christmas living room. Empty stockings are hung up next to the fireplace, waiting for Saint Nicholas to come down the chimney and fill them with small treats. Holiday treats are scattered about. A bowl of mixed nuts, the holiday nutcracker, and a few clementines. A string of coloured lights winds its way up an evergreen.
Perhaps a few of these images are familiar, or maybe they’re just settings you’ve seen in a movie. It doesn’t really matter what the living room looks like though. The important thing is to ground yourself in your own experiences before tackling a new subject. Instead of trying to brute-force your way into new information, as an adult learner constantly ask yourself: ‘What is this like? What does this remind me of? What do I already know that I can use to map out this new territory?’ It’s okay if the map isn’t perfect. As you refine your understanding of a new topic, you’ll outgrow the initial metaphors, analogies, and comparisons.
With apologies to Mr. Moore, let’s give it a try.
Getting Interrupted in Git
When on the roof there arose such a clatter!
You’re happily working on your software project when all of a sudden there are freaking reindeer on the roof! Whatever you’ve been working on is going to need to wait while you investigate the commotion.
If you’ve got even a little bit of experience working with Git, you know that you cannot simply change what you’re working on in times of emergency. If you’ve been doing work, you have a dirty working directory and you cannot change branches, or push your work to a remote repository while in this state.
Up to this point, you’ve probably dealt with emergencies by making a somewhat useless commit with a message something to the effect of ‘switching branches for a sec’. This isn’t exactly helpful to future you, as commits should really contain whole ideas of completed work. If you get interrupted, especially if there are reindeer on the roof, the chances are very high that you weren’t finished with what you were working on.
You don’t need to make useless commits though. Instead, you can use the stash command. This command allows you to temporarily set aside all of your changes so that you can come back to them later. In this sense, stash is like setting your book down on the side table (or pushing the cat off your lap) so you can go investigate the noise on the roof. You aren’t putting your book away though, you’re just putting it down for a moment so you can come back and find it exactly the way it was when you put it down.
Let’s say you’ve been working in the branch waiting-for-st-nicholas, and now you need to temporarily set aside your changes to see what the noise was on the roof:
$ git stash
After running this command, all uncommitted work will be temporarily removed from your working directory, and you will be returned to whatever state you were in the last time you committed your work.
With the book safely on the side table, and the cat safely off your lap, you are now free to investigate the noise on the roof. It turns out it’s not reindeer after all, but just your boss who thought they’d help out by writing some code on the project you’ve been working on. Bless. Rolling your eyes, you agree to take a look and see what kind of mischief your boss has gotten themselves into this time.
You fetch an updated list of branches from the remote repository, locate the branch your boss had been working on, and checkout a local copy:
$ git fetch
$ git branch -r
$ git checkout -b helpful-boss-branch origin/helpful-boss-branch
You are now in a local copy of the branch where you are free to look around, and figure out exactly what’s going on.
You sigh audibly and say, ‘Okay. Tell me what was happening when you first realised you’d gotten into a mess’ as you look through the log messages for the branch.
$ git log --oneline
$ git log
By using the log command you will be able to review the history of the branch and find out the moment right before your boss ended up stuck on your roof.
You may also want to compare the work your boss has done to the main branch for your project. For this article, we’ll assume the main branch is named master.
$ git diff master
Looking through the commits, you may be able to see that things started out okay but then took a turn for the worse.
Checking out a single commit
Using commands you’re already familiar with, you can rewind through history and take a look at the state of the code at any moment in time by checking out a single commit, just like you would a branch.
Using the log command, locate the unique identifier (commit hash) of the commit you want to investigate. For example, let’s say the unique identifier you want to checkout is 25f6d7f.
$ git checkout 25f6d7f
Note: checking out '25f6d7f'.
You are in 'detached HEAD' state. You can look around,
make experimental changes and commit them, and you can
discard any commits you make in this state without
impacting any branches by performing another checkout.
If you want to create a new branch to retain commits you create, you may do so (now or later) by using @-b@ with the checkout command again. Example:
$ git checkout -b new_branch_name
HEAD is now at 25f6d7f... Removed first paragraph.
This is usually where people start to panic. Your boss screwed something up, and now your HEAD is detached. Under normal circumstances, these words would be a very good reason to panic.
Take a deep breath. Nothing bad is going to happen. Being in a detached HEAD state just means you’ve temporarily disconnected from a known chain of events. In other words, you’re currently looking at the middle of a story (or branch) about what happened – and you’re not at the endpoint for this particular story.
Git allows you to view the history of your repository as a timeline (technically it’s a directed acyclic graph). When you make commits which are not associated with a branch, they are essentially inaccessible once you return to a known branch. If you make commits while you’re in a detached HEAD state, and then try to return to a known branch, Git will give you a warning and tell you how to save your work.
$ git checkout master
Warning: you are leaving 1 commit behind, not connected to
any of your branches:
7a85788 Your witty holiday commit message.
If you want to keep them by creating a new branch, this may be a good time to do so with:
$ git branch new_branch_name 7a85788
Switched to branch 'master'
Your branch is up-to-date with 'origin/master'.
So, if you want to save the commits you’ve made while in a detached HEAD state, you simply need to put them on a new branch.
$ git branch saved-headless-commits 7a85788
With this trick under your belt, you can jingle around in history as much as you’d like. It’s not like sliding around on a timeline though. When you checkout a specific commit, you will only have access to the history from that point backwards in time. If you want to move forward in history, you’ll need to move back to the branch tip by checking out the branch again.
$ git checkout helpful-boss-branch
You’re now back to the present. Your HEAD is now pointing to the endpoint of a known branch, and so it is no longer detached. Any changes you made while on your adventure are safely stored in a new branch, assuming you’ve followed the instructions Git gave you. That wasn’t so scary after all, now, was it?
Back to our reindeer problem.
If your boss is anything like the bosses I’ve worked with, chances are very good that at least some of their work is worth salvaging. Depending on how your repository is structured, you’ll want to capture the good work using one of several different methods.
Back in the living room, we’ll use our bowl of nuts to illustrate how you can rescue a tiny bit of work.
Saving just one commit
About that bowl of nuts. If you’re like me, you probably had some favourite kinds of nuts from an assorted collection. Walnuts were generally the most satisfying to crack open. So, instead of taking the entire bowl of nuts and dumping it into a stocking (merging the stocking and the bowl of nuts), we’re just going to pick out one nut from the bowl. In Git terms, we’re going to cherry-pick a commit and save it to another branch.
First, checkout the main branch for your development work. From this branch, create a new branch where you can copy the changes into.
$ git checkout master
$ git checkout -b rescue-the-boss
From your boss’s branch, helpful-boss-branch locate the commit you want to keep.
$ git log --oneline helpful-boss-branch
Let’s say the commit ID you want to keep is e08740b. From your rescue branch, use the command cherry-pick to copy the changes into your current branch.
$ git cherry-pick e08740b
If you review the history of your current branch again, you will see you now also have the changes made in the commit in your boss’s branch.
At this point you might need to make a few additional fixes to help your boss out. (You’re angling for a bonus out of all this. Go the extra mile.) Once you’ve made your additional changes, you’ll need to add that work to the branch as well.
$ git add [filename(s)]
$ git commit -m "Building on boss's work to improve feature X."
Go ahead and test everything, and make sure it’s perfect. You don’t want to introduce your own mistakes during the rescue mission!
Uploading the fixed branch
The next step is to upload the new branch to the remote repository so that your boss can download it and give you a huge bonus for helping you fix their branch.
$ git push -u origin rescue-the-boss
Cleaning up and getting back to work
With your boss rescued, and your bonus secured, you can now delete the local temporary branches.
$ git branch --delete rescue-the-boss
$ git branch --delete helpful-boss-branch
And settle back into your chair to wait for Saint Nicholas with your book, your branch, and possibly your cat.
$ git checkout waiting-for-st-nicholas
$ git stash pop
Your working directory has been returned to exactly the same state you were in at the beginning of the article.
Having fun with analogies
I’ve had a bit of fun with analogies in this article. But sometimes those little twists on ideas can really help someone pick up a new idea (git stash: it’s like when Christmas comes around and everyone throws their fashion sense out the window and puts on a reindeer sweater for the holiday party; or git bisect: it’s like trying to find that one broken light on the string of Christmas lights). It doesn’t matter if the analogy isn’t perfect. It’s just a way to give someone a temporary hook into a concept in a way that makes the concept accessible while the learner becomes comfortable with it. As the learner’s comfort increases, the analogies can drop away, making room for the technically correct definition of how something works.
Or, if you’re like me, you can choose to never grow old and just keep mucking about in the analogies. I’d argue it’s a lot more fun to play with a string of Christmas lights and some holiday cheer than a directed acyclic graph anyway. |

Cohesive UX |
With Yosemite, Apple users can answer iPhone calls on their MacBooks. This is weird. And yet it’s representative of a greater trend toward cohesion.
Shortly after upgrading to Yosemite, a call came in on my iPhone and my MacBook “rang” in parallel. And I was all, like, “Wut?” This was a new feature in Yosemite, and honestly it was a little bizarre at first.
Apple promotional image showing a phone call ringing simultaneously on multiple devices.
However, I had just spoken at a conference on the very topic you’re reading about now, and therefore I appreciated the underlying concept: the cohesion of user experience, the cohesion of screens.
This is just one of many examples I’ve encountered since beginning to speak about this topic months ago. But before we get ahead of ourselves, let’s look back at the past few years, specifically the role of responsive web design.
RWD != cohesive experience
I needn’t expound on the virtues of responsive web design (RWD). You’ve likely already encountered more than a career’s worth on the topic. This is a good thing. Count me in as one of its biggest fans.
However, if we are to sing the praises of RWD, we must also acknowledge its shortcomings. One of these is that RWD ends where the browser ends. For all its goodness, RWD really has no bearing on native apps or any other experiences that take place outside the browser. This makes it challenging, therefore, to create cohesion for multi-screen users if RWD is the only response to “let’s make it work everywhere.”
We need something that incorporates the spirit of RWD while unifying all touchpoints for the entire user experience—single device or several devices, in browser or sans browser, native app or otherwise.
I call this cohesive UX, and I believe it’s the next era of successful user experiences.
Toward a unified whole
Simply put, the goal of cohesive UX is to deliver a consistent, unified user experience regardless of where the experience begins, continues, and ends.
Two facets are vital to cohesive UX:
Function and form
Data symmetry
Let’s examine each of these.
Function AND form
Function over form, of course. Right? Not so fast, kiddo.
Consider Bruce Lawson’s dad. After receiving an Android phone for Christmas and thumbing through his favorite sites, he was puzzled why some looked different from their counterparts on the desktop. “When a site looked radically different,” Bruce observed, “he’d check the URL bar to ensure that he’d typed in the right address. In short, he found RWD to be confusing and it meant he didn’t trust the site.” A lack of cohesive form led to a jarring experience for Bruce’s dad.
Now, if I appear to be suggesting websites must look the same in every browser—you already learned they needn’t—know that I recognize the importance of context, especially in regards to mobile. I made a case for this more than seven years ago.
Rather, cohesive UX suggests that form deserves the same respect as function when crafting user experiences that span multiple screens or devices. And users are increasingly comfortable traversing media. For example, more than 40% of adults in the U.S. owning more than one device start an activity on one screen and finish it on another, according to a study commissioned by Facebook. I suspect that percentage will only increase in 2015, and I suspect the tech-affluent readers of 24 ways are among the 40%.
There are countless examples of cohesive form and function. Consider Gmail, which displays email conversations visually as a stack that can be expanded and collapsed like the bellows of an accordion. This visual metaphor has been consistent in virtually any instance of Gmail—website or app—since at least 2007 when I captured this screenshot on my Nokia 6680:
Screenshot captured while authoring Mobile Web Design (2007). Back then we didn’t call this an app, but rather a ‘smart client’.
When the holistic experience is cohesive as it is with Gmail, users’ mental models and even muscle memory are preserved.1 Functionality and aesthetics align with the expectations users have for how things should function and what they should look like. In other words, the experience is roughly the same across screens.
But don’t be ridiculous, peoples. Note that I said “roughly.” It’s important to avoid mindless replication of aesthetics and functionality for the sake of cohesion. Again, the goal is a unified whole, not a carbon copy. Affordances and concessions should be made as context and intuition require. For example, while Facebook users are accustomed to top-aligned navigation in the browser, they encounter bottom-aligned navigation in the iOS app as justified by user testing:
The iOS app model has held up despite many attempts to better it: http://t.co/rSMSAqeh9m pic.twitter.com/mBp36lAEgc— Luke Wroblewski (@lukew) December 10, 2014
Despite the (rather minor) lack of consistency in navigation placement, other elements such as icons, labels, and color theme work in tandem to produce a unified, holistic whole.
Data symmetry
Data symmetry involves the repetition, continuity, or synchronicity of data across screens, devices, and platforms. As regards cohesive UX, data includes not just the material (such as an article you’re writing on Medium) but also the actions that can be performed on or with that material (such as Medium’s authoring tools). That is to say, “sync verbs, not just nouns” (Josh Clark).
In my estimation, Amazon is an archetype of data symmetry, as is Rdio. When logged in, data is shared across virtually any device of any kind, irrespective of using a browser or native app. Add a product to your Amazon cart from your phone during the morning commute, and finish the transaction at work on your laptop. Easy peasy.
Amazon’s aesthetics are crazy cohesive, to boot:
Amazon web (left) and native app (right).
With Rdio, not only are playlists and listening history synced across screens as you would expect, but the cohesion goes even further. Rdio’s remote control feature allows you to control music playing on one device using another device, all in real time.
Rdio’s remote control feature, as viewed on my MacBook while music plays on my iMac.
At my office I often work from my couch using my MacBook, but my speakers are connected to my iMac. When signed in to Rdio on both devices, my MacBook serves as proxy for controlling Rdio on my iMac, much the same as any Yosemite-enabled device can serve as proxy for an incoming iPhone call.
Me, in my office. Note the iMac and speakers at far right.
This is a brilliant example of cohesive design, and it’s executed entirely via the cloud.
Things to consider
Consider the following when crafting cohesive experiences:
Inventory the elements that comprise your product experience, and cohesify them.2
Consider things such as copy, tone, typography, iconography, imagery, flow, placement, brand identification, account data, session data, user preferences, and so on. Then, create cohesion among these elements to the greatest extent possible, while adapting to context as needed.
Store session data in the cloud rather than locally.
For example, avoid using browser cookies to store shopping cart data, as cookies are specific to a single browser on a single device. Instead, store this data in the cloud so it can be accessed from other devices, as well as beyond the browser.
Consider using web views when developing your native app.
“You’re already using web apps in native wrappers without even noticing it,” Lukas Mathis contends. “The fact that nobody even notices, the fact that this isn’t a story, shows that, when it comes to user experience, web vs. native doesn’t matter anymore.” Web views essentially allow you to display HTML content inside a native wrapper. This can reduce the time and effort needed to make the overall experience cohesive. So whereas the navigation bar may be rendered by the app, for example, the remaining page display may be rendered via the web. There’s readily accessible documentation for using web views in C++, iOS, Android, and so forth.
Nature is calling
Returning to the example of Yosemite and sychronized phone calls, is it really that bizarre in light of cohesive UX? Perhaps at first. But I suspect that, over time, Yosemite’s cohesiveness — and the cohesiveness of other examples like the ones we’ve discussed here — will become not only more natural but more commonplace, too.
1 I browse Flipboard on my iPad nearly every morning as part of my breakfast routine. Swiping horizontally advances to the next page. Countless times I’ve done the same gesture in Flipboard for iPhone only to have it do nothing. This is because the gesture for advancing is vertical on phones. I’m so conditioned to the horizontal swipe that I often fail to make the switch to vertical swipe, and apparently others suffer from the same muscle memory, too.
2 Cohesify isn’t a thing. But chances are you understood what I meant. Yay neologism! |

Five Ways to Animate Responsibly |
It’s been two years since I wrote about “Flashless Animation” on this very site. Since then, animation has steadily begun popping up on websites, from sleek app-like user interfaces to interactive magazine-like spreads. It’s an exciting time for web animation wonks, interaction developers, UXers, UI designers and a host of other acronyms!
But in our rush to experiment with animation it seems that we’re having fewer conversations about whether or not we should use it, and more discussions about what we can do with it. We spend more time fretting over how to animate all the things at 60fps than we do devising ways to avoid incapacitating users with vestibular disorders.
I love web animation. I live it. And I make adorably silly things with it that have no place on a self-respecting production website. I know it can be abused. We’ve all made fun of Flash-turbation. But how quickly we forget the lessons we learned from that period of web design. Parallax scrolling effects may be the skip intro of this generation. Surely we have learned better in the sobering up period between Flash and the web animation API.
So here are five bits of advice we can use to pull back from the edge of animation abuse. With these thoughts in mind, we can make 2015 the year web animation came into its own.
Animate deliberately
Sadly, animation is considered decorative by the bulk of the web development community. UI designers and interaction developers know better, of course. But when I’m teaching a workshop on animation for interaction, I know that my students face an uphill battle against decision makers who consider it nice to have, and tack it on at the end of a project, if at all.
This stigma is hard to shake. But it starts with us using animation deliberately or not at all. Poorly considered, tacked-on animation will often cause more harm than good. Users may complain that it’s too slow or too fast, or that they have no idea what just happened.
When I was at Chrome Dev Summit this year, I had the privilege to speak with Roma Sha, the UX lead behind Polymer’s material design (with the wonderful animation documentation). I asked her what advice she’d give to people using animation and transitions in their own designs. She responded simply: animate deliberately. If you cannot afford to slow down to think about animation and make well-informed and well-articulated decisions on behalf of the user, it is better that you not attempt it at all. Animation takes energy to perform, and a bad animation is worse than none at all.
It takes more than twelve principles
We always try to draw correlations between disparate things that spark our interest. Recently it feels like more and more people are putting the The Illusion of Life on their reading shelf next to Understanding Comics. These books give us so many useful insights from other industries. However, we should never mistake a website for a comic book or an animated feature film. Some of these concepts, while they help us see our work in a new light, can be more or less relevant to producing said work.
The illusion of life from cento lodigiani on Vimeo.
I am specifically thinking of the twelve principles of animation put forth by Disney studio veterans in that great tome The Illusion of Life. These principles are very useful for making engaging, lifelike animation, like a ball bouncing or a squirrel scampering, or the physics behind how a lightbox should feel transitioning off a page. But they provide no direction at all for when or how something should be animated as part of a greater interactive experience, like how long a drop-down should take to fully extend or if a group of manipulable objects should be animated sequentially or as a whole.
The twelve principles are a great place to start, but we have so much more to learn. I’ve documented at least six more functions of interactive animation that apply to web and app design. When thinking about animation, we should consider why and how, not just what, the physics. Beautiful physics mean nothing if the animation is superfluous or confusing.
Useful and necessary, then beautiful
There is a Shaker saying: “Don’t make something unless it is both necessary and useful; but if it is both necessary and useful, don’t hesitate to make it beautiful.” When it comes to animation and the web, currently there is very little documentation about what makes it useful or necessary. We tend to focus more on the beautiful, the delightful, the aesthetic. And while aesthetics are important, they take a back seat to the user’s overall experience.
The first time I saw the load screen for Pokemon Yellow on my Game Boy, I was enthralled. By the sixth time, I was mashing the start button as soon as Game Freak’s logo hit the screen. What’s delightful and meaningful to us while working on a project is not always so for our users. And even when a purely delightful animation is favorably received, as with Pokemon Yellow’s adorable opening screen, too many repetitions of the cutest but ultimately useless animation, and users start to resent it as a hindrance.
If an animation doesn’t help the user in some way, by showing them where they are or how two elements on a page relate to each other, then it’s using up battery juice and processing cycles solely for the purpose of delight. Hardly the best use of resources.
Rather than animating solely for the sake of delight, we should first be able to articulate two things the animation does for the user. As an example, take this menu icon from Finethought.com (found via Use Your Interface). The menu icon does two things when clicked:
It gives the user feedback by animating, letting the user know its been clicked.
It demonstrates its changed relationship to the page’s content by morphing into a close button.
Assuming we have two good reasons to animate something, there is no reason our third cannot be to delight the user.
Go four times faster
There is a rule of thumb in the world of traditional animation which is applicable to web animation: however long you think your animation should last, take that time and halve it. Then halve it again! When we work on an animation for hours, our sense of time dilates. What seems fast to us is actually unbearably slow for most users. In fact, the most recent criticism from users of animated interfaces on websites seems to be, “It’s so slow!” A good animation is unobtrusive, and that often means running fast.
When getting your animations ready for prime time, reduce those durations to 25% of their original speed: a four-second fade out should be over in one.
Install a kill switch
No matter how thoughtful and necessary an animation, there will be people who become physically sick from seeing it. For these people, we must add a way to turn off animations on the website.
Fortunately, web designers are already thinking of ways to empower users to make their own decisions about how they experience the web. As an example, this site for the animated film Little from the Fish Shop allows users to turn off most of the parallax effects. While it doesn’t remove the animation entirely, this website does reduce the most nauseating of the animations.
Animation is a powerful tool in our web design arsenal. But we must take care: if we abuse animation it might get a bad reputation; if we underestimate it, it won’t be prioritized. But if we wield it thoughtfully, use it where it is both necessary and useful, and empower users to turn it off, animation is a tool that will help us build things that are easier to use and more delightful for years to come.
Let’s make 2015 the year web animation went to work for users. |

Collaborative Responsive Design Workflows |
Much has been written about workflow and designer-developer collaboration in web design, but many teams still struggle with this issue; either with how to adapt their internal workflow, or how to communicate the need for best practices like mobile first and progressive enhancement to their teams and clients. Christmas seems like a good time to have another look at what doesn’t work between us and how we can improve matters.
Why is it so difficult?
We’re still beginning to understand responsive design workflows, acknowledging the need to move away from static design tools and towards best practices in development. It’s not that we don’t want to change – so why is it so difficult?
Changing the way we do something that has become routine is always problematic, even with small things, and the changes today’s web environment requires from web design and development teams are anything but small.
Although developers also have a host of new skills to learn and things to consider, designers are probably the ones pushed furthest out of their comfort zones: as well as graphic design, a web designer today also needs an understanding of interaction design and ergonomics, because more and more websites are becoming tools rather than pages meant to be read like a book or magazine. In addition to that there are thousands of different devices and screen sizes on the market today that layout and interactions need to work on.
These aspects make it impossible to design in a static design tool, so beyond having to learn about new aspects of design, the designer has to either learn how to code or learn to work with a responsive design tool.
Why do it
That alone is enough to leave anyone overwhelmed, as learning a new skill takes time and slows you down in a project – and on most projects time is in short supply. Yet we have to make time or fall behind in the industry as others pitch better, interactive designs. For an efficient workflow, both designers and developers must familiarise themselves with new tools and techniques.
A designer has to be able to play with ideas, make small adjustments here and there, look at the result, go back to the settings and make further adjustments, and so on. You can only realistically do that if you are able to play with all the elements of a design, including interactivity, accessibility and responsiveness.
Figuring out the right breakpoints in a layout is one of the foremost reasons for designing in a responsive design tool. Even if you create layouts for three viewport sizes (i.e. smartphone, tablet and the most common desktop size), you’d only cover around 30% of visitors and you might miss problems like line breaks and padding at other viewport sizes.
Another advantage is consistency. In static design tools changes will not be applied across all your other layouts. A developer referring back to last week’s comps might work with outdated metrics. Furthermore, you cannot easily test what impact changes might have on previously designed areas. In a dynamic design tool such changes will be applied to the entire design and allow you to test things in site areas you had already finished.
No static design tool allows you to do this, and having somebody else produce a mockup from your static designs or wireframes will duplicate work and is inefficient.
How to do it
When working in a responsive design tool rather than in the browser, there is still the question of how and when to communicate with the developer. I have found that working with Sass in combination with a visual style guide is very efficient, but it does need careful planning: fundamental metrics for padding, margins and font sizes, but also design elements like sliders, forms, tabs, buttons and navigational elements, should be defined at the beginning of a project and used consistently across the site. Working with a grid can help you develop a consistent design language across your site.
Create a visual style guide that shows what the elements look like and how they behave across different screen sizes – and when interacted with. Put all metrics on paddings, margins, breakpoints, widths, colours and so on in a text document, ideally with names that your developer can use as Sass variables in the CSS. For example:
$padding-default-vertical: 1.5em;
Developers, too, need an efficient workflow to keep code maintainable and speed up the time needed for more complex interactions with an eye on accessibility and performance. CSS preprocessors like Sass allow you to work with variables and mixins for default rules, as well as style sheet partials for different site areas or design elements. Create your own boilerplate to use for your projects and then update your variables with the information from your designer for each individual project.
How to get buy-in
One obstacle when implementing responsive design, accessibility and content strategy is the logistics of learning new skills and iterating on your workflow. Another is how to sell it. You might expect everyone on a project (including the client) to want to design and develop the best website possible: ultimately, a great site will lead to more conversions. However, we often hear that people find it difficult to convince their teammates, bosses or clients to implement best practices.
Why is that? Well, I believe a lot of it is down to how we sell it. You will have experienced this yourself: some people you trust to know what they are talking about, and others you don’t. Think about why you trust that first person but don’t buy what the other one is telling you. It is likely because person A has a self-assured, calm and assertive demeanour, while person B seems insecure and apologetic. To sell our ideas, we need to become person A! For a timid designer or developer suffering from imposter syndrome (like many of us do in this industry) that is a difficult task. So how can we become more confident in selling our expertise?
Write
We need to become experts. And I mean not just in writing great code or coming up with beautiful designs but at explaining why we’re doing what we’re doing. Why do you code this way or that? Why is this the best layout? Why does a website have to be accessible and responsive? Write about it. Putting your thoughts down on paper or screen is a really efficient way of getting your head around a topic and learning to make a case for something. You may even find that you come up with new ideas as you are writing, so you’ll become a better designer or developer along the way.
Talk
Then, talk about it. Start out in front of your team, then do a lightning talk at a web event near you, then a longer talk or workshop. Having to talk about a topic is going to help you put into spoken words the argument that you’ve previously put together in writing. Writing comes more easily when you’re starting out but we use a different register when writing than talking and you need to learn how to speak your case. Do the talk a couple of times and after each talk make adjustments where you found it didn’t work well. By this time, you are more than ready to make your case to the client. In fact, you’ve been ready since that first talk in front of your colleagues ;)
Pitch
Pitches used to be based on a presentation of static layouts for for three to five typical pages and three different designs. But if we want to sell interactivity, structure, usability, accessibility and responsiveness, we need to demonstrate these things and I believe that it can only do us good. I have seen a few pitches sitting in the client’s chair and static layouts are always sort of dull. What makes a website a website is the fact that I can interact with it and smooth interactions or animations add that extra sparkle.
I can’t claim personal experience for this one but I’d be bold and go for only one design. One demo page matching the client’s corporate design but not any specific page for the final site. Include design elements like navigation, photography, typefaces, article layout (with real content), sliders, tabs, accordions, buttons, forms, tables (yes, tables) – everything you would include in a style tiles document, only interactive. Demonstrate how the elements behave when clicked, hovered and touched, and how they change across different screen sizes. You may even want to demonstrate accessibility features like tabbed navigation and screen reader use.
Obviously, there are many approaches that will work in different situations but don’t give up on finding a process that works for you and that ultimately allows you to build delightful, accessible, responsive user experiences for the web. Make time to try new tools and techniques and don’t just work on them on the side – start using them on an actual project. It is only when we use a tool or process in the real world that we become true experts. Remember your driving lessons: once the instructor had explained how to operate the car, you were sent to practise driving on the road in actual traffic! |

SEO in 2015 (and Why You Should Care) |
If your business is healthy, you can always find plenty of reasons to leave SEO on your to-do list in perpetuity. After all, SEO is technical, complicated, time-consuming and potentially dangerous. The SEO industry is full of self-proclaimed gurus whose lack of knowledge can be deadly. There’s the terrifying fact that even if you dabble in SEO in the most gentle and innocent way, you might actually end up in a worse state than you were to begin with.
To make matters worse, Google keeps changing the rules. There have been a bewildering number of major updates, which despite their cuddly names have had a horrific impact on website owners worldwide.
Fear aside, there’s also the issue of time. It’s probably tricky enough to find the time to read this article. Setting up, planning and executing an SEO campaign might well seem like an insurmountable obstacle.
So why should you care enough about SEO to do it anyway?
The main reason is that you probably already see between 30% and 60% of your website traffic come from the search engines. That might make you think that you don’t need to bother, because you’re already doing so well. But you’re almost certainly wrong.
If you have a look through the keyword data in your Google Webmaster Tools account, you’ll probably see that around 30–50% of the keywords used to find your website are brand names – the names of your products or companies. These are searches carried out by people who already know about you. But the people who don’t know who you are but are searching for what you sell aren’t finding you right now. This is your opportunity.
If a person goes looking for a company or product by name, Google will steer them towards what they’re looking for. Their intelligence does have limits, however, and even though they know your name they won’t be completely clear about what you sell. That’s where SEO would come in.
Still need more convincing? How about the fact that the seeming complexities of SEO mean that your competition are almost certainly neglecting it too. They have the same reservations as you about complexity, time and danger, and hopefully they aren’t reading this article and so are none the wiser of the well-kept secret: that 70% of SEO is easy.
I’m going to lead you through what you need to do to tap into that stream of people looking for what you sell right now.
What is real SEO?
Real SEO is all about helping Google understand the content of your website. It’s about steering, guiding and assisting Google. Not manipulating it.
It’s easy to assume that Google already understands the content and relevance of each and every page on your website, but the fact is that it needs a fair amount of hand-holding. Fortunately, helping Google along really isn’t very difficult at all.
Rest assured that real SEO has nothing to do with keyword stuffing, keyword density, hacks, tricks or cunning techniques. If you hear any of these terms from your SEO advisor, run away from them as quickly as you can.
Understanding your current situation – Google Analytics
Before you can do anything to improve your SEO status, you need to get an idea of how you’re already doing. Below is a very quick and easy way of doing so.
1. Open up your Google Analytics account.
2. Click on the date range selector on the top-right of the interface and change the year of the first date to last year. So 12 Dec 2014 will become 12 Dec 2013. Then click on Apply.
3. Click on the All Sessions rectangle towards the top-left, click once on Organic Traffic and click Apply.
4. Click the little black-and-white squares icon that has now appeared under the date selector on the top-right, and drag the slider all the way over to Higher Precision.
5. Change the interval buttons on the top-right of the graph to Week to make this easier to digest.
At this point your graph should look something like this:
It’s worth noting the approximate proportion of your visitors that currently come from organic sources.
6. Click the little downwards arrow to the right of the All Sessions rectangle and choose Remove, so that we’re only looking at the organic traffic on its own.
7. Click on Select a metric next to the Sessions button above the graph and select Pages / Session. You should then see something like this:
In the example above we can see that the quantity of traffic has been increasing since the middle of August, but the quality of the traffic (as measured by the number of pages per session) has fallen significantly.
How you choose to view this is down to your own graph, recent history and interpretation of events, but this should give you an indication of how things stand at the present time. Trends are often much more revealing than a snapshot of a brief moment in time.
Your Google Webmaster Tools data
If you’re not very familiar with your Google Webmaster Tools account, it’s really worth taking ten to fifteen minutes to see what’s on offer. I can’t recommend this enough. From the point of view of an SEO health check, I’d advise you to look into the HTML Improvements, Crawl Errors and Crawl Stats, and most importantly the Search Queries.
From what you see here and the trends shown in your Analytics data, you should now have a good idea of your current status. If you want to explore further, I recommend Screaming Frog as a good diagnostics tool, or Botify if your website is large or unusually complex.
Combining the data into something useful
Your Google Analytics session will have shown you how you’re doing from an SEO point of view in terms of the quantity and, to some extent, the quality of your visitors. But it’s only showing you what is already working. In other words: the people who are finding you on the search engines, and clicking on your links.
The Google Webmaster Tools search query data, on the other hand, will give you a better idea of what isn’t working. It will show you the keyword searches that are getting you listed in the results, but which aren’t necessarily getting clicked. And it doesn’t take much by the way of expertise to see why.
For example, if you see your targeted keyword, which you feel is extremely relevant, has generated over 2,000 impressions in the last month but produced only two clicks, you’ll probably find a very low average position. Bear in mind that an average position of fourteen will mean being around halfway down the second page of results. Think about how rarely you go beyond the first two or three listings, never mind to the second page of results, and you’ll understand why the click-through rate is so low.
So now you have an idea of what you’re being found for at the present time. But what about the other terms?
What would you like to be found for?
This is one of the more common SEO mistakes, on a number of different levels.
Many businesses assume that they don’t need to worry about keyword research. They think they know what terms people use to find what they sell, and they also assume that Google understands the content on their website. This is incorrect on all counts.
A better starting point is to brainstorm a small number of your most obvious keywords, then run them through Google’s Keyword Planner. Ignore the information in the Ad group ideas tab, and instead go straight to the Keyword ideas tab. Rather than wade through the very unfriendly interface, I recommend downloading the data as a spreadsheet, in which not only is more detail included, but you can also slice, dice, sort and report the data as required.
From there you can delete all the irrelevant columns, and start working your way through the list, deleting any irrelevant keywords as you go along.
It’s around this stage that you may hit a problem in terms of where to focus your efforts. The number of reported searches for a given keyword is of course important, but so is the level of competition. Ideally, you’d like keywords with plenty of searches but not too much competition.
I personally like to factor both together by adding a column that simply divides the number of searches squared by the level of competition:
(number of searches × number of searches) ÷ competition
There are plenty of alternatives to this basic formula, but I like it for ease of use and simplicity. Once I’ve added this column, I then sort the data by this value (largest to smallest) and I then only usually need ten to fifteen keywords at most to give me plenty of ideas to work with.
This is a slightly involved but effective methodology for keyword research, as what you’re left with is a list of keywords that both Google and you consider to be relevant to the content of your website. And relevance is an important concept in SEO.
Real SEO keyword research is about making sure that your customers, website and Google are all in agreement and alignment over the content of your website. Other sources of inspiration and ideas include having a look at what terms your competition are targeting, Google Trends and, of course, Google Suggest. If you’re not sure where to find these things, you can probably work out where to search for them!
If you want to dive further into understanding your current search engine status, search for some of the better keywords that you just discovered and see where you rank compared to your competition. Note that it’s vital to avoid Google serving up personalised results, so either use the privacy, incognito or anonymous mode of your browser for the searches, or use a browser that you don’t normally use. I hope this is Internet Explorer. If what you find isn’t great, don’t despair: everything in SEO is fixable (terms and conditions may apply).
Putting it all together
You should now have a good idea of where things stand with your current search engine traffic, and a solid list of keywords that you’re not getting visitors for but very much want.
All that’s left now is to work out how to use these keywords. But before we do, let’s take a quick step back.
If you have in any way kept up with what’s been happening in SEO over the last couple of years, you’ll have probably heard about Google updates with names like Panda, Hummingbird, Phantom, Pirate and more.
I won’t go into the technical details of what Google is doing, but it is important to understand why they’re trying to do it. At the most basic level, Google understands that there’s a very real problem with people who are trying manipulate its index. In response to this, Google is trying to clean up its results. They don’t want people getting fed up with bad results and considering other options – have you even tried Bing?
This is extremely important. Remember earlier when I said that 70% of SEO was easy? That rule still applies. So, for example, if you have a list of keywords that you know are relevant to what you sell, then all you need to do is create great content for them. Incredibly, that’s all there is to it (terms and conditions apply again, unfortunately – see below).
There is, however, one simple rule to be consistently followed without exception: that the content you create should not only be good quality and completely original, but it should also be written primarily for the human visitor and not the search engine spider.
In other words, if you create some fantastic content for a keyword like “choosing a small business HR service”, then the article should not only make perfect sense if read out loud (as opposed to the same phrase being repeated fifteen times), but also provide real value to the person reading it.
So the process is simple:
Choose your keywords
Create spectacular content
Wait. Is it really that simple?
Unfortunately there’s a lot more to the other 30% of SEO than just creating great content and waiting for the visitors. There are issues like helping Google understand the content on your pages and website, incoming links, page authority, domain authority, usage patterns, spam factors, canonical issues and much more.
But there’s the often overlooked fact about Google: it actually does a reasonable job of working out what’s on your website and (to some extent) understanding the gist of it. If you’ve never done any SEO on your website but still get some traffic from Google, this is why.
Even without dabbling in the other 30% of SEO, by creating the right content for the right visitors using the precise language and terminology that your potential customers are using, you’re significantly better off than your competition. And you can only gain from this.
When you’ve checked this off your to-do list and made it an ingrained part of your content creation process, then you’re ready to delve into the other 30% of SEO. The not-so-easy side.
Until then, work on understanding your current situation, exploring the opportunities, creating a list of good keywords, creating the right content for them, and starting 2015 with a little bit of smart, safe and real SEO. |

Naming Things |
There are only two hard things in computer science: cache invalidation and naming things.
Phil Karlton
Being a professional web developer means taking responsibility for the code you write and ensuring it is comprehensible to others. Having a documented code style is one means of achieving this, although the size and type of project you’re working on will dictate the conventions used and how rigorously they are enforced.
Working in-house may mean working with multiple developers, perhaps in distributed teams, who are all committing changes – possibly to a significant codebase – at the same time. Left unchecked, this codebase can become unwieldy. Coding conventions ensure everyone can contribute, and help build a product that works as a coherent whole.
Even on smaller projects, perhaps working within an agency or by yourself, at some point the resulting product will need to be handed over to a third party. It’s sensible, therefore, to ensure that your code can be understood by those who’ll eventually take ownership of it.
Put simply, code is read more often than it is written or changed. A consistent and predictable naming scheme can make code easier for other developers to understand, improve and maintain, presumably leaving them free to worry about cache invalidation.
Let’s talk about semantics
Names not only allow us to identify objects, but they can also help us describe the objects being identified.
Semantics (the meaning or interpretation of words) is the cornerstone of standards-based web development. Using appropriate HTML elements allows us to create documents and applications that have implicit structural meaning. Thanks to HTML5, the vocabulary we can choose from has grown even larger.
HTML elements provide one level of meaning: a widely accepted description of a document’s underlying structure. It’s only with the mutual agreement of browser vendors and developers that <p> indicates a paragraph.
Yet (with the exception of widely accepted microdata and microformat schemas) only HTML elements convey any meaning that can be parsed consistently by user agents. While using semantic values for class names is a noble endeavour, they provide no additional information to the visitor of a website; take them away and a document will have exactly the same semantic value.
I didn’t always think this was the case, but the real world has a habit of changing your opinion. Much of my thinking around semantics has been informed by the writing of my peers. In “About HTML semantics and front-end architecture”, Nicholas Gallagher wrote:
The important thing for class name semantics in non-trivial applications is that they be driven by pragmatism and best serve their primary purpose – providing meaningful, flexible, and reusable presentational/behavioural hooks for developers to use.
These thoughts are echoed by Harry Roberts in his CSS Guidelines:
The debate surrounding semantics has raged for years, but it is important that we adopt a more pragmatic, sensible approach to naming things in order to work more efficiently and effectively. Instead of focussing on ‘semantics’, look more closely at sensibility and longevity – choose names based on ease of maintenance, not for their perceived meaning.
Naming methodologies
Front-end development has undergone a revolution in recent years. As the projects we’ve worked on have grown larger and more important, our development practices have matured. The pros and cons of object-orientated approaches to CSS can be endlessly debated, yet their introduction has highlighted the usefulness of having documented naming schemes.
Jonathan Snook’s SMACSS (Scalable and Modular Architecture for CSS) collects style rules into five categories: base, layout, module, state and theme. This grouping makes it clear what each rule does, and is aided by a naming convention:
By separating rules into the five categories, naming convention is beneficial for immediately understanding which category a particular style belongs to and its role within the overall scope of the page. On large projects, it is more likely to have styles broken up across multiple files. In these cases, naming convention also makes it easier to find which file a style belongs to.
I like to use a prefix to differentiate between layout, state and module rules. For layout, I use l- but layout- would work just as well. Using prefixes like grid- also provide enough clarity to separate layout styles from other styles. For state rules, I like is- as in is-hidden or is-collapsed. This helps describe things in a very readable way.
SMACSS is more a set of suggestions than a rigid framework, so its ideas can be incorporated into your own practice. Nicholas Gallagher’s SUIT CSS project is far more strict in its naming conventions:
SUIT CSS relies on structured class names and meaningful hyphens (i.e., not using hyphens merely to separate words). This helps to work around the current limits of applying CSS to the DOM (i.e., the lack of style encapsulation), and to better communicate the relationships between classes.
Over the last year, I’ve favoured a BEM-inspired approach to CSS. BEM stands for block, element, modifier, which describes the three types of rule that contribute to the style of a single component. This means that, given the following markup:
<ul class=“sleigh”>
<li class=“sleigh__reindeer sleigh__reindeer––famous”>Rudolph</li>
<li class=“sleigh__reindeer”>Dasher</li>
<li class=“sleigh__reindeer”>Dancer</li>
<li class=“sleigh__reindeer”>Prancer</li>
<li class=“sleigh__reindeer”>Vixen</li>
<li class=“sleigh__reindeer”>Comet</li>
<li class=“sleigh__reindeer”>Cupid</li>
<li class=“sleigh__reindeer”>Dunder</li>
<li class=“sleigh__reindeer”>Blixem</li>
</ul>
I know that:
.sleigh is a containing block or component.
.sleigh__reindeer is used only as a descendent element of .sleigh.
.sleigh__reindeer––famous is used only as a modifier of .sleigh__reindeer.
With this naming scheme in place, I know which styles relate to a particular component, and which are shared. Beyond reducing specificity-related head-scratching, this approach has given me a framework within which I can consistently label items, and has sped up my workflow considerably.
Each of these methodologies shows that any robust CSS naming convention will have clear rules around case (lowercase, camelCase, PascalCase) and the use of special (allowed) characters like hyphens and underscores.
What makes for a good name?
Regardless of higher-level conventions, there’s no getting away from the fact that, at some point, we’re still going to have to name things. Recognising that classes should be named with other developers in mind, what makes for a good name?
Understandable
The most important aspect is for a name to be understandable. Words used in your project may come from a variety of sources: some may be widely understood, and others only be recognised by people working within a particular environment.
Culture
Most words you’ll choose will have common currency outside the world of web development, although they may have a particular interpretation among developers (think menu, list, input). However, words may have a narrower cultural significance; for example, in Germany and other German-speaking countries, impressum is the term used for legally mandated statements of ownership.
Industry
Industries often use specific terms to describe common business practices and concepts. Publishing has a number of these (headline, standfirst, masthead, colophon…) all have well understood meanings – and not all of them are relevant to online usage.
Organisation
Companies may have internal names (or nicknames) for their products and services. The Guardian is rife with such names: bisons (and buffalos), pixies (and super-pixies), bentos (and mini-bentos)… all of which mean something very different outside the organisation. Although such names can be useful inside smaller teams, in larger organisations they can become a barrier to entry, a sort of secret code used among employees who have been around long enough to know what they mean.
Product
Your team will undoubtedly have created names for specific features or interface components used in your product. For example, at Clearleft we coined the term gravigation for a navigation bar that was pinned to the bottom of the viewport. Elements of a visual design language may have names, too. Transport for London’s bar and circle logo is known internally as the roundel, while Nike’s logo is called the swoosh. Branding agencies often christen colours within a brand palette, too, either to evoke aspects of the identity or to indicate intended usage.
Once you recognise the origin of the words you use, you’ll be better able to judge their appropriateness. Using Latin words for class names may satisfy a need to use semantic-sounding terms but, unless you work in a company whose employees have a basic grasp of Latin, a degree of translation will be required. Military ranks might be a clever way of declaring sizes without implying actual values, but I’d venture most people outside the armed forces don’t know how they’re ordered.
Obvious
Quite often, the first name that comes into your head will be the best option. Names that obliquely reference the function of a class (e.g. receptacle instead of container, kevlar instead of no-bullets) only serve to add an additional layer of abstraction. Don’t overthink it!
One way of knowing if the names you use are well understood is to look at what similar concepts are called in existing vocabularies. schema.org, Dublin Core and the BBC’s ontologies are all useful sources for object names.
Functional
While we’ve learned to avoid using presentational classes, there remains a tension between naming things based on their content, and naming them for their intended presentation or behaviour (which may change at different breakpoints). Rather than think about a component’s appearance or behaviour, instead look to its function, its purpose. To clarify, ask what a component’s function is, and not how the component functions.
For example, the Guardian’s internal content system uses the following names for different types of image placement: supporting, showcase and thumbnail, with inline being the default. These options make no promise of the resulting position on a webpage (or smartphone app, or television screen…), but do suggest intended use, and therefore imply the likely presentation.
Consistent
Being consistent in your approach to names will allow for easier naming of successive components, and extending the vocabulary when necessary. For example, a predictably named hierarchy might use names like primary and secondary. Should another level need to be added, tertiary is clearly be preferred over third.
Appropriate
Your project will feature a mix of style rules. Some will perform utility functions (clearing floats, removing bullets from a list, reseting margins), while others will perform specific functions used only once or twice in a project. Names should reflect this. For commonly used classes, be generic; for unique components be more specific.
It’s also worth remembering that you can use multiple classes on an element, so combining both generic and specific can give you a powerful modular design system:
Generic: list
Specific: naughty-children
Combined: naughty-children list
If following the BEM methodology, you might use the following classes:
Generic: list
Specific: list––nice-children
Combined: list list––nice-children
Extensible
Good naming schemes can be extended. One way of achieving this is to use namespaces, which are basically a way of grouping related names under a higher-level term.
Microformats are a good example of a well-designed naming scheme, with many of its vocabularies taking property names from existing and related specifications (e.g. hCard is a 1:1 representation of vCard). Microformats 2 goes one step further by grouping properties under several namespaces:
h-* for root class names (e.g. h-card)
p-* for simple (text) properties (e.g. p-name)
u-* for URL properties (e.g. u-photo)
dt-* for date/time properties (e.g. dt-bday)
e-* for embedded markup properties (e.g. e-note)
The inclusion of namespaces is a massive improvement over the earlier specification, but the downside is that microformats now occupy five separate namespaces. This might be problematic if you are using u-* for your utility classes. While nothing will break, your naming system won’t be as robust, so plan accordingly.
(Note: Microformats perform a very specific function, separate from any presentational concerns. It’s therefore considered best practice to not use microformat classes as styling hooks, but instead use additional classes that relate to the function of the component and adhere to your own naming conventions.)
Short
Names should be as long as required, but no longer. When looking for words to describe a particular function, I try to look for single words where possible. Avoid abbreviations unless they are understood within the contexts described above. rrp is fine if labelling a recommended retail price in an online shop, but not very helpful if used to mean ragged-right paragraph, for example.
Fun!
Finally, names can be an opportunity to have some fun! Names can give character to a project, be it by providing an outlet for in-jokes or adding little easter eggs for those inclined to look.
The copyright statement on Apple’s website has long been named sosumi, a word that has a nice little history inside Apple. Until recently, the hamburger menu icon on the Guardian website was labelled honest-burger, after the developer’s favourite burger restaurant.
A few thoughts on preprocessors
CSS preprocessors have solved a lot of problems, but they have an unfortunate downside: they require you to name yet more things! Whereas we needed to worry only about style rules, now we need names for variables, mixins, functions… oh my!
A second article could be written about naming these, so for now I’ll offer just a few thoughts. The first is to note that preprocessors make it easier to change things, as they allow for DRYer code. So while the names of variables are important (and the advice in this article still very much applies), you can afford to relax a little.
Looking to name colour variables? If possible, find out if colours have been assigned names in a brand palette. If not, use obvious names (based on appearance or function, depending on your preference) and adapt as the palette grows. If it becomes difficult to name colours that are too similar, I’d venture that the problem lies with the design rather than the naming scheme.
The same is true for responsive breakpoints. Preprocessors allow you to move awkward naming conventions out of the markup and into the CSS. Although terms like mobile, tablet and desktop are not desirable given the need to think about device-agnostic design, if these terms are widely understood within a product team and among stakeholders, using them will ensure everyone is using the same language (they can always be changed later).
It still feels like we’re at the very beginning of understanding how preprocessors fit into a development workflow, if at all! I suspect over the next few years, best practices will emerge for all of these considerations. In the meantime, use your brain!
Even with sensible rules and conventions in place, naming things can remain difficult, but hopefully I’ve made this exercise a little less painful. Christmas is a time of giving, so to the developer reading your code in a year’s time, why not make your gift one of clearer class names. |

JavaScript Modules the ES6 Way |
JavaScript admittedly has plenty of flaws, but one of the largest and most prominent is the lack of a module system: a way to split up your application into a series of smaller files that can depend on each other to function correctly.
This is something nearly all other languages come with out of the box, whether it be Ruby’s require, Python’s import, or any other language you’re familiar with. Even CSS has @import! JavaScript has nothing of that sort, and this has caused problems for application developers as they go from working with small websites to full client-side applications. Let’s be clear: it doesn’t mean the new module system in the upcoming version of JavaScript won’t be useful to you if you’re building smaller websites rather than the next Instagram.
Thankfully, the lack of a module system will soon be a problem of the past. The next version of JavaScript, ECMAScript 6, will bring with it a full-featured module and dependency management solution for JavaScript. The bad news is that it won’t be landing in browsers for a while yet – but the good news is that the specification for the module system and how it will look has been finalised. The even better news is that there are tools available to get it all working in browsers today without too much hassle. In this post I’d like to give you the gift of JS modules and show you the syntax, and how to use them in browsers today. It’s much simpler than you might think.
What is ES6?
ECMAScript is a scripting language that is standardised by a company called Ecma International. JavaScript is an implementation of ECMAScript. ECMAScript 6 is simply the next version of the ECMAScript standard and, hence, the next version of JavaScript. The spec aims to be fully comfirmed and complete by the end of 2014, with a target initial release date of June 2015. It’s impossible to know when we will have full feature support across the most popular browsers, but already some ES6 features are landing in the latest builds of Chrome and Firefox. You shouldn’t expect to be able to use the new features across browsers without some form of additional tooling or library for a while yet.
The ES6 module spec
The ES6 module spec was fully confirmed in July 2014, so all the syntax I will show you in this article is not expected to change. I’ll first show you the syntax and the new APIs being added to the language, and then look at how to use them today. There are two parts to the new module system. The first is the syntax for declaring modules and dependencies in your JS files, and the second is a programmatic API for loading in modules manually. The first is what most people are expected to use most of the time, so it’s what I’ll focus on more.
Module syntax
The key thing to understand here is that modules have two key components. First, they have dependencies. These are things that the module you are writing depends on to function correctly. For example, if you were building a carousel module that used jQuery, you would say that jQuery is a dependency of your carousel. You import these dependencies into your module, and we’ll see how to do that in a minute. Second, modules have exports. These are the functions or variables that your module exposes publicly to anything that imports it. Using jQuery as the example again, you could say that jQuery exports the $ function. Modules that depend on and hence import jQuery get access to the $ function, because jQuery exports it.
Another important thing to note is that when I discuss a module, all I really mean is a JavaScript file. There’s no extra syntax to use other than the new ES6 syntax. Once ES6 lands, modules and files will be analogous.
Named exports
Modules can export multiple objects, which can be either plain old variables or JavaScript functions. You denote something to be exported with the export keyword:
export function double(x) {
return x + x;
};
You can also store something in a variable then export it. If you do that, you have to wrap the variable in a set of curly braces.
var double = function(x) {
return x + x;
}
export { double };
A module can then import the double function like so:
import { double } from 'mymodule';
double(2); // 4
Again, curly braces are required around the variable you would like to import. It’s also important to note that from 'mymodule' will look for a file called mymodule.js in the same directory as the file you are requesting the import from. There is no need to add the .js extension.
The reason for those extra braces is that this syntax lets you export multiple variables:
var double = function(x) {
return x + x;
}
var square = function(x) {
return x * x;
}
export { double, square }
I personally prefer this syntax over the export function …, but only because it makes it much clearer to me what the module exports. Typically I will have my export {…} line at the bottom of the file, which means I can quickly look in one place to determine what the module is exporting.
A file importing both double and square can do so in just the way you’d expect:
import { double, square } from 'mymodule';
double(2); // 4
square(3); // 9
With this approach you can’t easily import an entire module and all its methods. This is by design – it’s much better and you’re encouraged to import just the functions you need to use.
Default exports
Along with named exports, the system also lets a module have a default export. This is useful when you are working with a large library such as jQuery, Underscore, Backbone and others, and just want to import the entire library. A module can define its default export (it can only ever have one default export) like so:
export default function(x) {
return x + x;
}
And that can be imported:
import double from 'mymodule';
double(2); // 4
This time you do not use the curly braces around the name of the object you are importing. Also notice how you can name the import whatever you’d like. Default exports are not named, so you can import them as anything you like:
import christmas from 'mymodule';
christmas(2); // 4
The above is entirely valid.
Although it’s not something that is used too often, a module can have both named exports and a default export, if you wish.
One of the design goals of the ES6 modules spec was to favour default exports. There are many reasons behind this, and there is a very detailed discussion on the ES Discuss site about it. That said, if you find yourself preferring named exports, that’s fine, and you shouldn’t change that to meet the preferences of those designing the spec.
Programmatic API
Along with the syntax above, there is also a new API being added to the language so you can programmatically import modules. It’s pretty rare you would use this, but one obvious example is loading a module conditionally based on some variable or property. You could easily import a polyfill, for example, if the user’s browser didn’t support a feature your app relied on. An example of doing this is:
if(someFeatureNotSupported) {
System.import('my-polyfill').then(function(myPolyFill) {
// use the module from here
});
}
System.import will return a promise, which, if you’re not familiar, you can read about in this excellent article on HTMl5 Rocks by Jake Archibald. A promise basically lets you attach callback functions that are run when the asynchronous operation (in this case, System.import), is complete.
This programmatic API opens up a lot of possibilities and will also provide hooks to allow you to register callbacks that will run at certain points in the lifetime of a module. Those hooks and that syntax are slightly less set in stone, but when they are confirmed they will provide really useful functionality. For example, you could write code that would run every module that you import through something like JSHint before importing it. In development that would provide you with an easy way to keep your code quality high without having to run a command line watch task.
How to use it today
It’s all well and good having this new syntax, but right now it won’t work in any browser – and it’s not likely to for a long time. Maybe in next year’s 24 ways there will be an article on how you can use ES6 modules with no extra work in the browser, but for now we’re stuck with a bit of extra work.
ES6 module transpiler
One solution is to use the ES6 module transpiler, a compiler that lets you write your JavaScript using the ES6 module syntax (actually a subset of it – not quite everything is supported, but the main features are) and have it compiled into either CommonJS-style code (CommonJS is the module specification that NodeJS and Browserify use), or into AMD-style code (the spec RequireJS uses). There are also plugins for all the popular build tools, including Grunt and Gulp.
The advantage of using this transpiler is that if you are already using a tool like RequireJS or Browserify, you can drop the transpiler in, start writing in ES6 and not worry about any additional work to make the code work in the browser, because you should already have that set up already. If you don’t have any system in place for handling modules in the browser, using the transpiler doesn’t really make sense. Remember, all this does is convert ES6 module code into CommonJS- or AMD-compliant JavaScript. It doesn’t do anything to help you get that code running in the browser, but if you have that part sorted it’s a really nice addition to your workflow. If you would like a tutorial on how to do this, I wrote a post back in June 2014 on using ES6 with the ES6 module transpiler.
SystemJS
Another solution is SystemJS. It’s the best solution in my opinion, particularly if you are starting a new project from scratch, or want to use ES6 modules on a project where you have no current module system in place. SystemJS is a spec-compliant universal module loader: it loads ES6 modules, AMD modules, CommonJS modules, as well as modules that just add a variable to the global scope (window, in the browser).
To load in ES6 files, SystemJS also depends on two other libraries: the ES6 module loader polyfill; and Traceur. Traceur is best accessed through the bower-traceur package, as the main repository doesn’t have an easy to find downloadable version. The ES6 module load polyfill implements System.import, and lets you load in files using it. Traceur is an ES6-to-ES5 module loader. It takes code written in ES6, the newest version of JavaScript, and transpiles it into ES5, the version of JavaScript widely implemented in browsers. The advantage of this is that you can play with the new features of the language today, even though they are not supported in browsers. The drawback is that you have to run all your files through Traceur every time you save them, but this is easily automated. Additionally, if you use SystemJS, the Traceur compilation is done automatically for you.
All you need to do to get SystemJS running is to add a <script> element to load SystemJS into your webpage. It will then automatically load the ES6 module loader and Traceur files when it needs them. In your HTML you then need to use System.import to load in your module:
<script>
System.import('./app');
</script>
When you load the page, app.js will be asynchronously loaded. Within app.js, you can now use ES6 modules. SystemJS will detect that the file is an ES6 file, automatically load Traceur, and compile the file into ES5 so that it works in the browser. It does all this dynamically in the browser, but there are tools to bundle your application in production, so it doesn’t make a lot of requests on the live site. In development though, it makes for a really nice workflow.
When working with SystemJS and modules in general, the best approach is to have a main module (in our case app.js) that is the main entry point for your application. app.js should then be responsible for loading all your application’s modules. This forces you to keep your application organised by only loading one file initially, and having the rest dealt with by that file.
SystemJS also provides a workflow for bundling your application together into one file.
Conclusion
ES6 modules may be at least six months to a year away (if not more) but that doesn’t mean they can’t be used today. Although there is an overhead to using them now – with the work required to set up SystemJS, the module transpiler, or another solution – that doesn’t mean it’s not worthwhile. Using any module system in the browser, whether that be RequireJS, Browserify or another alternative, requires extra tooling and libraries to support it, and I would argue that the effort to set up SystemJS is no greater than that required to configure any other tool. It also comes with the extra benefit that when the syntax is supported in browsers, you get a free upgrade. You’ll be able to remove SystemJS and have everything continue to work, backed by the native browser solution.
If you are starting a new project, I would strongly advocate using ES6 modules. It is a syntax and specification that is not going away at all, and will soon be supported in browsers. Investing time in learning it now will pay off hugely further down the road.

Websites of Christmas Past, Present and Future |
The websites of Christmas past
The first website was created at CERN. It was launched on 20 December 1990 (just in time for Christmas!), and it still works today, after twenty-four years. Isn’t that incredible?!
Why does this website still work after all this time? I can think of a few reasons.
First, the authors of this document chose HTML. Of course they couldn’t have known back then the extent to which we would be creating documents in HTML, but HTML always had a lot going for it. It’s built on top of plain text, which means it can be opened in any text editor, and it’s pretty readable, even without any parsing.
Despite the fact that HTML has changed quite a lot over the past twenty-four years, extensions to the specification have always been implemented in a backwards-compatible manner. Reading through the 1992 W3C document HTML Tags, you’ll see just how it has evolved. We still have h1 – h6 elements, but I’d not heard of the <plaintext> element before. Despite being deprecated since HTML2, it still works in several browsers. You can see it in action on my website.
As well as being written in HTML, there is no run-time compilation of code; the first website simply consists of HTML files transmitted over the web. Due to its lack of complexity, it stood a good chance of surviving in the turbulent World Wide Web.
That’s all well and good for a simple, static website. But websites created today are increasingly interactive. Many require a login and provide experiences that are tailored to the individual user. This type of dynamic website requires code to be executed somewhere.
Traditionally, dynamic websites would execute such code on the server, and transmit a simple HTML file to the user. As far as the browser was concerned, this wasn’t much different from the first website, as the additional complexity all happened before the document was sent to the browser.
Doing it all in the browser
In 2003, the first single page interface was created at slashdotslash.com. A single page interface or single page app is a website where the page is created in the browser via JavaScript. The benefit of this technique is that, after the initial page load, subsequent interactions can happen instantly, or very quickly, as they all happen in the browser.
When software runs on the client rather than the server, it is often referred to as a fat client. This means that the bulk of the processing happens on the client rather than the server (which can now be thin).
A fat client is preferred over a thin client because:
It takes some processing requirements away from the server, thereby reducing the cost of servers (a thin server requires cheaper, or fewer servers).
They can often continue working offline, provided no server communication is required to complete tasks after initial load.
The latency of internet communications is bypassed after initial load, as interactions can appear near instantaneous when compared to waiting for a response from the server.
But there are also some big downsides, and these are often overlooked:
They can’t work without JavaScript. Obviously JavaScript is a requirement for any client-side code execution. And as the UK Government Digital Service discovered, 1.1% of their visitors did not receive JavaScript enhancements. Of that 1.1%, 81% had JavaScript enabled, but their browsers failed to execute it (possibly due to dropping the internet connection). If you care about 1.1% of your visitors, you should care about the non-JavaScript experience for your website.
The browser needs to do all the processing. This means that the hardware it runs on needs to be fast. It also means that we require all clients to have largely the same capabilities and browser APIs.
The initial payload is often much larger, and nothing will be rendered for the user until this payload has been fully downloaded and executed. If the connection drops at any point, or the code fails to execute owing to a bug, we’re left with the non-JavaScript experience.
They are not easily indexed as every crawler now needs to run JavaScript just to receive the content of the website.
These are not merely edge case issues to shirk off. The first three issues will affect some of your visitors; the fourth affects everyone, including you.
What problem are we trying to solve?
So what can be done to address these issues? Whereas fat clients solve some inherent issues with the web, they seem to create as many problems. When attempting to resolve any issue, it’s always good to try to uncover the original problem and work forwards from there. One of the best ways to frame a problem is as a user story. A user story considers the who, what and why of a need. Here’s a template:
As a {who} I want {what} so that {why}
I haven’t got a specific project in mind, so let’s refer to the who as user. Here’s one that could explain the use of thick clients.
As a user I want the site to respond to my actions quickly so that I get immediate feedback when I do something.
This user story could probably apply to a great number of websites, but so could this:
As a user I want to get to the content quickly, so that I don’t have to wait too long to find out what the site is all about or get the content I need.
A better solution
How can we balance both these user needs? How can we have a website that loads fast, and also reacts fast? The solution is to have a thick server, that serves the complete document, and then a thick client, that manages subsequent actions and replaces parts of the page. What we’re talking about here is simply progressive enhancement, but from the user’s perspective.
The initial payload contains the entire document. At this point, all interactions would happen in a traditional way using links or form elements. Then, once we’ve downloaded the JavaScript (asynchronously, after load) we can enhance the experience with JavaScript interactions. If for whatever reason our JavaScript fails to download or execute, it’s no biggie – we’ve already got a fully functioning website. If an API that we need isn’t available in this browser, it’s not a problem. We just fall back to the basic experience.
This second point, of having some minimum requirement for an enhanced experience, is often referred to as cutting the mustard, first used in this sense by the BBC News team. Essentially it’s an if statement like this:
if('querySelector' in document
&& 'localStorage' in window
&& 'addEventListener' in window) {
// bootstrap the JavaScript application
}
This code states that the browser must support the following methods before downloading and executing the JavaScript:
document.querySelector (can it find elements by CSS selectors)
window.localStorage (can it store strings)
window.addEventListener (can it bind to events in a standards-compliant way)
These three properties are what the BBC News team decided to test for, as they are present in their website’s JavaScript. Each website will have its own requirements. The last method, window.addEventListener is in interesting one. Although it’s simple to bind to events on IE8 and earlier, these browsers have very inconsistent support for standards. Making any JavaScript-heavy website work on IE8 and earlier is a painful exercise, and comes at a cost to all users on other browsers, as they’ll download unnecessary code to patch support for IE.
JavaScript API support by browser.
I discovered that IE8 supports 12% of the current JavaScript APIs, while IE9 supports 16%, and IE10 51%. It seems, then, that IE10 could be the earliest version of IE that I’d like to develop JavaScript for. That doesn’t mean that users on browsers earlier than 10 can’t use the website. On the contrary, they get the core experience, and because it’s just HTML and CSS, it’s much more likely to be bug-free, and could even provide a better experience than trying to run JavaScript in their browser. They receive the thin client experience.
By reducing the number of platforms that our enhanced JavaScript version supports, we can better focus our efforts on those platforms and offer an even greater experience to those users. But we can only do that if we use progressive enhancement. Otherwise our website would be completely broken for all other users.
So what we have is a thick server, capable of serving the entire website to our users, complete with all core functionality needed for our users to complete their tasks; and we have a thick client on supported browsers, which can bring an even greater experience to those users.
This is all transparent to users. They may notice that the website seems snappier on the new iPhone they received for Christmas than on the Windows 7 machine they got five years ago, but then they probably expected it to be faster on their iPhone anyway.
Isn’t this just more work?
It’s true that making a thick server and a thick client is more work than just making one or the other. But there are some big advantages:
The website works for everyone.
You can decide when users get the enhanced experience.
You can enhance features in an iterative (or agile) manner.
When the website breaks, it doesn’t break down.
The more you practise this approach, the quicker you will become.
The websites of Christmas present
The best way to discover websites using this technique of progressive enhancement is to disable JavaScript and see if the website breaks. I use the Web Developer extension, which is available for Chrome and Firefox. It lets me quickly disable JavaScript.

24 ways navigation with JavaScript disabled.
24 ways navigation with working JavaScript.
Google search will also work without JavaScript. You won’t get instant search results or any prerendering, because those are enhancements.
For a more app-like example, try using Twitter. Without JavaScript, it still works, and looks nearly identical. But when you load JavaScript, links open in modal windows and all pages are navigated much quicker, as only the content that has changed is loaded. You can read about how they achieved this in Twitter’s blog posts Improving performance on twitter.com and Implementing pushState for twitter.com.
Unfortunately Facebook doesn’t use progressive enhancement, which not only means that the website doesn’t work without JavaScript, but it takes longer to load. I tested it on WebPagetest and if you compare the load times of Twitter and Facebook, you’ll notice that, despite putting similar content on the page, Facebook takes two and a half times longer to render the core content on the page.
Facebook takes two and a half times longer to load than Twitter.
Websites of Christmas yet to come
Every project is different, and making a website that enjoys a long life, or serves a larger number of users may or may not be a high priority. But I hope I’ve convinced you that it certainly is possible to look to the past and future simultaneously, and that there can be significant advantages to doing so. |

Meet for Learning |
“I’ve never worked in a place like this,” said one of my direct reports during our daily stand-up meeting.
And with that statement, my mind raced to the most important thing about lawyering that I’ve learned from decades of watching lawyers lawyer on TV: don’t ask a question you don’t know the answer to.
But I couldn’t stop myself. I wanted to learn more. The thought developed in my mind. The words formed in my mouth. And the vocalization occurred: “A place like this?”
“I’ve never worked where people are so honest and transparent about things.”
Designing a learning-centered culture
Before we started Center Centre, Jared Spool and I discussed both the larger goals and the smaller details of this new UX design school. We talked about things like user experience, curriculum, and structure.
We discussed the pattern we saw in our research. Hiring managers told us time and again that great designers have excellent technical and interpersonal skills. But, more importantly, the best designers are lifelong learners—they are willing and able to learn how to do new things. Learning this led us to ask a critical question: how would we intentionally design a learning-centered experience?
To craft the experience we were aiming for, we knew we had to create a learning-centered culture for our students and our employees. We knew that our staff would need to model the behaviors our students needed to learn. We knew the best way to shape the culture was to work with our direct reports—our directs—to develop the behaviors we wanted them to exemplify.
To craft the experience we were aiming for, we knew we had to create a learning-centered culture for our students and our employees. We knew that our staff would need to model the behaviors our students needed to learn.
Building a learning team
Our learning-centered culture starts with our staff. We believe in transparency. Transparency builds trust. Effective organizations have effective teams who trust each other as individuals.
One huge way we build that trust and provide opportunities for transparency is in our meetings. (I know, I know—meetings! Yuck!) But seriously, running and participating in effective meetings is a great opportunity to build a learning-centered culture.
Meetings—when done well—allow individuals time to come together, to share, and to listen. These behaviors, executed on a consistent and regular basis, build honest and trusting relationships.
An effective meeting is one that achieves the desired outcomes of that meeting. While different meetings aim for different results, at Center Centre all meetings have a secondary goal: meet for learning.
A framework for learning-centered meetings
We’ve developed a framework for our meetings. We use it for all our meetings, which means attendees know what to expect. It also saves us from reinventing the wheel in each meeting.
These basic steps help our meetings focus on the valuable face-to-face interaction we’re having, and help us truly begin to learn from one another.
An agenda for a staff meeting.
Use effective meeting basics
Prepare for the meeting before the meeting.
If you’re running the meeting, prepare a typed agenda and share it before the meeting. Agendas have start times for each item.
Start the meeting on time. Don’t wait for stragglers.
Define ground rules. Get input from attendees. Recurring meetings don’t have to do this every time.
Keep to the meeting agenda. Put off-topic questions and ideas in a parking lot, a visual document that everyone can see, so you can address the questions and ideas later.
Finish on time. And if you’ve reached the meeting’s goals, finish early.
Parking lots where ideas on sticky notes can be posted for later consideration.
Focus to learn
Have tech-free meetings: no laptops, no phones, no things with notifications.
Bring a notebook and a pen.
Take notes by hand. You’re not taking minutes, you’re writing to learn.
Come with a learning mindset
Ask: what are our goals for this meeting? (Hopefully answered by the meeting agenda.)
Ask: what can I learn overall?
Ask: what can I learn from each of my colleagues?
Ask: what can I share that will help the team learn overall?
Ask: what can I share that will help each of my colleagues learn?
Investing in regularly scheduled learning-centered meetings
At Center Centre, we have two types of recurring all-staff meetings: daily stand-ups and weekly staff meetings. (We are a small organization, so it makes sense to meet as an entire group.)
Yes, that means we spend thirty minutes each day in stand-up, for a total of two and a half hours of stand-up meeting time each week. And, yes, we also have a weekly ninety-minute sit-down staff meeting on top of that. This investment in time is an investment in learning.
We use these meetings to build our transparency, and, therefore, our trust. The regularity of these meetings helps us maintain ongoing, open sharing about our responsibilities, our successes, and our learning.
For instance, we answer five questions in our stand-up:
What did I get done since the last stand-up (I reported at)?
What is my goal to accomplish before the next stand-up?
What’s preventing me from getting these things done, if anything?
What’s the highest risk or most unknown thing right now about what I’m trying to get done?
What is the most important thing I learned since the last time we met and how will what I learned change the way I approach things in the future?
Each person writes out their answers to these questions before the meeting. Each person brings their answers printed on paper to the meeting. And each person brings a pen to jot down notes.
Notes compiled for a stand-up meeting.
During the stand-up, each person shares their answers to the five questions. To sustain a learning-centered culture, the fifth question is the most important question to answer. It allows individual reflection focused on learning. Sometimes this isn’t an easy question to answer. It makes us stretch. It makes us think.
By sharing our individual answers to the fifth question, we open ourselves up to the group. When we honestly share what we’ve learned, we openly admit that we didn’t know something. Sharing like this would be scary (and even risky) if we didn’t have a learning-centered culture.
We often share the actual process of how we learned something. By listening, each of us is invited to learn more about the topic at hand, consider what more there is to learn about that topic, and even gain insights into other methods of learning—which can be applied to other topics.
Sharing the answers to the fifth question also allows opportunities for further conversations. We often take what someone has individually learned and find ways to apply it for our entire team in support of our organization. We are, after all, learning together.
Building individual learners
We strive to grow together as a team at Center Centre, but we don’t lose sight of the importance of the individuals who form our team. As individuals, we bring our goals, dreams, abilities, and prior knowledge to the team.
To build learning teams, we must build individual learners. A team made up of lifelong learners, who share their learning and learn from each other, is a team that will continually produce better results.
As a manager, I need to meet each direct where they are with their current abilities and knowledge. Then, I can help them take their skills and knowledge base to the next levels. This process requires each individual direct to engage in professional development.
We believe effective managers help their directs engage in behaviors that support growth and development. Effective managers encourage and support learning.
Our weekly one-on-ones
One way we encourage learning is through weekly one-on-ones. Each of my directs meets with me, individually, for thirty minutes each week. The meeting is their meeting. It is not my meeting.
My direct sets the agenda. They talk about what they want to talk about. They can talk about work. They can talk about things outside of work. They can talk about their health, their kids, and even their cat. Whatever is important to them is important to me. I listen. I take notes.
Although the direct sets the specific agenda, the meeting has three main parts. Approximately ten minutes for them (the direct), ten minutes for me (the manager), and ten minutes for us to talk about their future within—and beyond—our organization.
Coaching for future performance
The final third of our one-on-one is when I coach my directs. Coaching looks to the direct’s future performance. It focuses on developing the direct’s skills.
Coaching isn’t hard. It doesn’t take much time. For me, it usually takes less than five minutes a week during a one-on-one.
The first time I coach one of my directs, I ask them to brainstorm about the skills they want to improve. They usually already have an idea about this. It’s often something they’ve wanted to work on for some time, but didn’t think they had the time or the knowhow to improve.
If a direct doesn’t know what they want to improve, we discuss their job responsibilities—specifically the aspects of the job that concern them.
Coaching provides an opportunity for me to ask, “In your job, what are the required skills that you feel like you don’t have (or know well enough, or perform effectively, or use with ease)?”
Sometimes I have to remind a direct that it’s okay not to know how to do something (even if it’s a required part of their job). After all, our organization is a learning organization. In a learning organization, no one knows everything but everyone is willing to learn anything.
After we review the job responsibilities together, I ask my direct what skill they’d like to work to improve. Whatever they choose, we focus on that skill for coaching—I’ve found my directs work better when they’re internally motivated.
Sometimes the first time I talk with a direct about coaching, they get a bit anxious. If this happens, I share a personal story about my professional learning journey. I say something like:
I didn’t know how to make a school before we started to make Center Centre.
I didn’t know how to manage an entire team of people—day in and day out—until I started managing a team of people every day.
When I realized that I was the boss—and that the success of the school would hinge, at least in part, on my skills as a manager—I was a bit terrified. I was missing an important skill set that I needed to know (and I needed to know well).
When I first understood this, I felt bad—like I should have already known how to be a great manager. But then I realized, I’d never faced this situation. I’d never needed to know how to use this skill set in this way.
I worked through my anxiety about feeling inadequate. I decided I’d better learn how to be an effective manager because the school needed me to be one. You needed me to be one.
Every day, I work to improve my management skills. You’ve probably noticed that some days I’m better at it than others. I try not to beat myself up about this, although it’s hard—I’d like to be perfect at it. But I’m not.
I know that if I make a conscious, daily effort to learn how to be a better manager, I’ll continue to improve. So that’s what I do.
Every day I learn. I learn by doing. I learn how to be better than I was the day before. That’s what I ask of you.
Once we determine the skill the direct wants to learn, we figure out how they can go about learning it. I ask: “How could you learn this skill?”
We brainstorm for two or three minutes about this. We write down every idea that comes to mind, and we write it so both of us can easily see the options (both whiteboards and sticky notes on the wall work well for this exercise).
Read a book. Research online. Watch a virtual seminar. Listen to a podcast. Talk to a mentor. Reach out to an expert. Attend a conference. Shadow someone else while they do the skill. Join a professional organization.
The goal is to get the direct on a path of self-development. I’m coaching their development, but I’m not the main way my direct will learn this new skill.
I ask my direct which path seems like the best place to start. I let them choose whatever option they want (as long as it works with our budget). They are more likely to follow through if they are in control of this process.
Next, we work to break down the selected path into tasks. We only plan one week’s worth of tasks. The tasks are small, and the deadlines are short. My direct reports when each task is completed.
At our next one-on-one, I ask my direct about their experience learning this new skill.
Rinse. Repeat.
That’s it. I spend five minutes a week talking with each direct about their individual learning. They develop their professional skills, and together we’re creating a learning-centered culture.
Asking questions I don’t know the answer to
When my direct said, “I’ve never worked where people are so honest and transparent about things,” it led me to believe that all this is working. We are building a learning-centered culture.
This week I was reminded that creating a learning-centered culture starts not just with the staff, but with me. When I challenge myself to learn and then share what I’m currently learning, my directs want to learn more about what I’m learning about.
For example, I decided I needed to improve my writing skills. A few weeks ago, I realized that I was sorely out of practice and I felt like I had lost my voice. So I started to write. I put words on paper. I felt overwhelmed. I felt like I didn’t know how to write anymore (at least not well or effectively).
I bought some books on writing (mostly Peter Elbow’s books like Writing with Power, Writing Without Teachers, and Vernacular Eloquence), and I read them. I read them all. Reading these books was part of my personal coaching. I used the same steps to coach myself as I use with my directs when I coach them.
In stand-ups, I started sharing what I accomplished (like I completed one of the books) and what I learned by doing—specific things, like engaging in freewriting and an open-ended writing process.
This week, I went to lunch with one of my directs. She said, “You’ve been talking about freewriting a lot. You’re really excited about it. Freewriting seems like it’s helping your writing process. Would you tell me more about it?”
So I shared the details with her. I shared the reasons why I think freewriting is helping. I’m not focused on perfection. Instead, each day I’m focused on spending ten, uninterrupted minutes writing down whatever comes to my mind. It’s opening my writing mind. It’s allowing my words to flow more freely. And it’s helping me feel less self-conscious about my writing.
She said, “Leslie, when you say you’re self-conscious about your writing, I laugh. Not because it’s funny. But because when I read what you write, I think, ‘What is there to improve?’ I think you’re a great writer. It’s interesting to know that you think you can be a better writer. I like learning about your learning process. I think I could do freewriting. I’m going to give it a try.”
There’s something magical about all of this. I’m not even sure I can eloquently put it into words. I just know that our working environment is something very different. I’ve never experienced anything quite like it. Somehow, by sharing that I don’t know everything and that I’m always working to learn more, I invite my directs to be really open about what they don’t know. And they see it’s possible always to learn and grow.
I’m glad I ignore all the lawyering I’ve learned from watching TV. I’m glad I ask the questions I don’t know the answers to. And I’m glad my directs do the same. When we meet for learning, we accelerate and amplify the learning process—building individual learners and learning teams. Embracing the unknown and working toward understanding is what makes our culture a learning-centered culture.

Don’t Push Through the Pain |
In 2004, I lost my web career. In a single day, it was gone. I was in too much pain to use a keyboard, a Wacom tablet (I couldn’t even click the pen), or a trackball. Switching my mouse to use my left (non-dominant) hand only helped a bit; then that hand went, too. I tried all the easy-to-find equipment out there, except for expensive gizmos with foot pedals. I had tingling in my fingers—which, when I was away from the computer, would rhythmically move as if some other being controlled them. I worried about Parkinson’s because the movements were so dramatic. Pen on paper was painful. Finally, I discovered one day that I couldn’t even turn a doorknob.
The only highlight was that I couldn’t dust, scrub, or vacuum. We were forced to hire someone to come in once a week for an hour to whip through the house. You can imagine my disappointment.
My injuries had gradually slithered into my life without notice. I’d occasionally have sore elbows, or my wrist might ache for a day, or my shoulders feel tight. But nothing to keyboard home about. That’s the critical bit of news. One day, you’re pretty fine. The next day, you don’t have your job—or any job that requires the use of your hands and wrists.
I had to walk away from the computer for over four months—and partially for several months more. That’s right: no income. If I hadn’t found a gifted massage therapist, the right book of stretches, the equipment I should have been using all along, and learned how to pay attention to my body—even just a little bit more—I quite possibly wouldn’t be writing this article today. I wouldn’t be writing anything, anywhere.
Most of us have heard of (and even claimed to have read all of) Mihaly Csikszentmihalyi, author of Flow: The Psychology of Optimal Experience, who describes the state of flow—the place our minds go when we are fully engaged and in our element. This lovely state of highly focused activity is deeply satisfying, often creative, and quite familiar to many of us on the web who just can’t quit until the copy sings or the code is untangled or we get our highest score yet in Angry Birds. Our minds may enter that flow, but too often as our brains take flight, all else recedes. And we leave something very important behind.
Our bodies.
My body wasn’t made to make the same minute movements thousands of times a day, most days of the year, for decades, and neither was yours. The wear and tear sneaks up on you, especially if you’re the obsessive perfectionist that we all pretend not to be. Oh? You’re not obsessed? I wasn’t like this all the time, but I remember sitting across from my husband, eating dinner, and I didn’t hear a word he said. I’d left my brain upstairs in my office, where it was wrestling in a death match with the box model or, God help us all, IE 5.2. I was a writer, too, and I was having my first inkling that I was a content strategist. Work was exciting. I could sit up late, in the flow, fingers flying at warp speed. I could sit until those wretched birds outside mocked me with their damn, cheerful “Hurray, it’s morning!” songs. Suddenly, while, say, washing dishes, the one magical phrase that captured the essence of a voice or idea would pop up, and I would have mowed down small animals and toddlers to get to my computer and hammer out that website or article, to capture that thought before it escaped. Note my use of the word hammer. Sound at all familiar?
But where was my body during my work? Jaw jutting forward to see the screen, feet oddly positioned—and then left in place like chunks of marble—back unsupported, fingers pounding the keys, wrists and arms permanently twisted in unnatural angles that we thought were natural. And clicking. Clicking, clicking, clicking that mouse. Thumbing tiny keyboards on phones. A lethal little gesture for tiny little tendons. Though I was fine from, say 1997 to 2004, by the end of 2004 this behavior culminated in disaster. I had repetitive stress injuries, aka repetitive motion injuries. As the Apple site says, “A brief exposure to these conditions would not cause harm. But a prolonged exposure may, in some people, result in reduced ability to function.” I’ll say.
I frantically turned to people on lists and forums. “Try a track ball.” Already did that. “Try a tablet.” Worse. One person wrote, “I still come here once in a while and can type a couple sentences, but I’ve permanently got thoracic outlet syndrome and I’ll never work again.” Oh, beauteous web, oh, long-distance friends, farewell.
The Wrist Bone’s Connected to the Brain Bone
That variation on the old song tells part of the story. Most people (and many of their physicians) believe that tingling fingers and aching wrists MUST be carpel tunnel syndrome. Nope. If your neck juts forward, it tenses and stays tense the entire time you work in that position. Remember how your muscles felt after holding a landline phone with your neck tilted to one side for a long client meeting? Regrettable. Tensing your shoulders because your chair’s not designed properly puts you at risk for thoracic outlet syndrome, a career-killer if ever there was one. The nerves and tendons in your neck and shoulder refer down your arms, and muscles swell around nerves, causing pain and dysfunction. Your elbows have a tendon that is especially vulnerable to repetitive movements (think tennis elbow). Your wrists are performing something akin to a circus act with one thousand shows a day.
So, all the fine tendons and ligaments in your fingers have problems that may not start at your wrists at all. Though some people truly do have carpal tunnel syndrome, my finger and wrist problems weren’t solved by heavily massaging my fingers (though, that was helpful, too) or my wrists. They were fixed by work on my neck, upper back, shoulders, arms, and elbows. This explains why many people have surgery for carpal tunnel syndrome and just months later say, “What?! How can I possibly have it again? I had an operation!” Well, fellow buckaroo, you may never have had carpel tunnel syndrome. You may have had—or perhaps will have—one long disaster area from your neck to your fingertips.
How to Crawl Back
Before trying extreme measures, you may be able to function again even if you feel hopeless. I managed to heal, and so have others, but I’ll always be at risk.
As Jen Simmons, of The Web Ahead podcast and other projects told me, “It took a long time to injure myself. It took a long time to get back to where I was. My right arm between my elbow and wrist would start aching intermittently. Eventually, my arm even ached at night. I started each day with yesterday’s pain.” Simple measures, used consistently, helped her back.
1. Massage therapy
I don’t remember what the rest of the world is like, but in Portland, Oregon, we have more than one massage therapy college. (Of course we do.) I saw a former teacher at the most respected school. This is not your “It was all so soothing. Why, I fell asleep!” massage. This is “Holy crap, he’s grinding his elbow into my armpit!“ massage therapy, with the emphasis on therapy. I owe him everything. Make sure you have someone who really knows what they’re doing. Get many referrals. Try a question, “Does my psoas muscle affect my back?” If they can’t answer it, flee. Regularly see the one you choose and after a while, depending on how injured you are, you may be able to taper off.
2. Change your equipment
You may need to be hands-on with several pieces of equipment before you find the ones that don’t cause more pain. Many companies have restocking fees, charges to ship the equipment you want to return, and other retail atrocities. Always be sure to ask what the return policies are at any company before purchasing.
Mice
You may have more success than I did with equipment such as the Wacom tablet. Mine came with a pen, and it hurt to repetitively click it. Trackballs are another option but, for many, they are better at prevention than recovery. But let’s get to the really effective stuff. One of the biggest sources of pain is using your mouse. One major reason is that your hand and wrist are in a perpetually unnatural position and you’re also moving your arm quite a bit. Each time you move the mouse, it is placing stress on your neck, shoulders and arms, because you need to lift them slightly in order to move the mouse and you need to angle your wrist. You may also be too injured to use the trackpad all the time, and this mouse, the vertical mouse is a dandy preventative measure, too. Shaking up your patterns is a wise move. I have long fingers, not especially thin, yet the small size works best for me. (They have larger choices available.) What?! A sideways mouse? Yep. All the weight of your hand will be resting on it in the handshake position. Your forearms aren’t constantly twisting over hill and dale. You aren’t using any muscles in your wrist or hand. They are relaxing. You’ll adapt in a day, and oh, oh, what a relief it is.
Keyboards
I really liked doing business with the people at Kinesis-Ergo. (I’m not affiliated with them in any way.) They have the vertical mouse and a number of keyboards. The one that felt the most natural to me, and, once again, it only takes a day to adapt, is the Freestyle2 for the Mac. They have several options. I kept the keyboard halves attached to each other at first, and then spread them apart a little more. I recommend choosing one that slants and can separate. You can adjust the angle. For a little extra, they’ll make sure it’s all set up and ready to go for you. I’m guessing that some Googling will find you similar equipment, wherever you live.
Warning: if you use the ergonomic keyboards, you may have fewer USB ports. The laptop will be too far away to see unless you find a satisfactory setup using a stand. This is the perfect excuse for purchasing a humongous display.
You may not look cool while jetting coast to coast in your skinny jeans and what appears to be the old-time orthopedic shoe version of computing gear. But once you have rested and used many of these suggestions consistently, you may be able to use your laptop or other device in all its lovely sleekness during the trip.
Other doohickies
The Kinesis site and The Human Solution have a wide selection of ergonomic products: standing desks, ergonomically correct chairs, and, yes, even things with foot pedals. Explore!
3. Stop clicking, at least for a while
Use keyboard shortcuts, but use them slowly. This is not the time to show off your skillz. You’ll be sort of like a recovering alcoholic, in that you’ll be a recovering repetitive stress survivor for the rest of your life, once you really injure yourself. Always be vigilant. There’s also a bit of software sold by The Human Solution and other places, and it was my salvation. It’s called the McNib for Macs, and the Nib for PCs. (I’ve only used the McNib.) It’s for click-free mousing. I found it tricky to use when writing markup and code, but you may become quite adept at it. A little rectangle pops up on your screen, you mouse over it and choose, let’s say, “Double-click.” Until you change that choice, if you mouse over a link or anything else, it will double-click it for you. All you do is glide your mouse around. Awkward for a day or two, but you’ll pick it up quickly. Though you can use it all day for work, even if you just use this for browsing LOLcats or Gary Vaynerchuk’s YouTube videos, it will help you by giving your fingers a sweet break.
But here’s the sad news. The developer who invented this died a few years ago. (Yes, I used to speak to him on the phone.) While it is for sale, it isn’t compatible with Mac OS X Lion or anything subsequent. PowerPC strikes again. His site is still up. Demos for use with older software can be downloaded free at his old site, or at The Human Solution. Perhaps an enterprising developer can invent something that would provide this help, without interfering with patents. Rumor has it among ergonomic retailers (yes, I’m like a police dog sniffing my way to a criminal once I head down a trail) that his company was purchased by a company in China, with no update in sight.
4. Use built-in features
That little microphone icon that comes up alongside the keyboard on your iPhone allows you to speak your message instead of incessantly thumbing it. I believe it works in any program that uses the keyboard. It’s not Siri. She’s for other things, like having a personal relationship with an inanimate object. Apple even has a good section on ergonomics. You think I’m intense about this subject? To improve your repetitive stress, Apple doesn’t want you to use oral contraceptives, alcohol, or tobacco, to which I say, “Have as much sex, bacon, and chocolate as possible to make up for it.”
Apple’s info even has illustrations of things like a faucet dripping into what is labeled a bucket full of “TRAUMA.” Sounds like upgrading to Yosemite, but I digress.
5. Take breaks
If it’s a game or other non-essential activity, take a break for a month. Fine, now that I’ve called games non-essential, I suppose you’ll all unfollow me on Twitter.
6. Whether you are sore or not, do stretches throughout the day
This is a big one. Really big. The best book on the subject of repetitive stress injuries is Conquering Carpal Tunnel Syndrome and Other Repetitive Strain Injuries: A Self-Care Program by Sharon J. Butler. Don’t worry, most of it is illustrations. Pretend it’s a graphic novel.
I’m notorious for never reading instructions, and who on earth reads the introduction of a book, unless they wrote it? I wrote a book a long time ago, and I bet my house, husband, and life savings that my own parents never read the intro. Well, I did read the intro to this book, and you should, too. Stretching correctly, in a way that doesn’t further hurt you, that keeps you flexible if you aren’t injured, that actually heals you, calls for precision. Read and you’ll see. The key is to stretch just until you start to feel the stretch, even if that’s merely a tiny movement. Don’t force anything past that point. Kindly nurse yourself back to health, or nurture your still-healthy body by stretching. Over the following days, weeks, months, you’ll be moving well past that initial stretch point.
The book is brimming with examples. You only have to pick a few stretches, if this is too much to handle. Do it every single day. I can tell you some of the best ones for me, but it depends on the person. You’ll also discover in Butler’s book that areas that you think are the problem are sometimes actually adjacent to the muscle or tendon that is the source of the problem. Add a few stretches or two for that area, too.
But please follow the instructions in the introduction. If you overdo it, or perform some other crazy-ass hijinks, as I would be tempted to do, I am not responsible for your outcome. I give you fair warning that I am not a healthcare provider. I’m just telling you as a friend, an untrained one, at that, who has been through this experience.
7. Follow good habits
Develop habits like drinking lots of water (which helps with lactic acid buildup in muscles), looking away from the computer for twenty seconds every twenty to thirty minutes, eating right, and probably doing everything else your mother told you to do. Maybe this is a good time to bring up flossing your teeth, and going outside to play instead of watching TV. As your mom would say, “It’s a beautiful day outside, what are you kids doing in here?”
8. Speak instead of writing, if you can
Amber Simmons, who is very smart and funny, once tweeted in front of the whole world that, “@carywood is a Skype whore.” I was always asking people on Twitter if we could Skype instead of using iChat or exchanging emails. (I prefer the audio version so I don’t have to, you know, do something drastic like comb my hair.) Keyboarding is tough on hands, whether you notice it or not at the time, and when doing rapid-fire back-and-forthing with people, you tend to speed up your typing and not take any breaks. This is a hand-killer. Voice chats have made such a difference for me that I am still a rabid Skype whore. Wait, did I say that out loud?
Speak your text or emails, using Dragon Dictate or other software. In about 2005, accessibility and user experience design expert, Derek Featherstone, in Canada, and I, at home, chatted over the internet, each of us using a different voice-to-text program. The programs made so many mistakes communicating with each other that we began that sort of endless, tearful laughing that makes you think someone may need to call an ambulance. This type of software has improved quite a bit over the years, thank goodness. Lack of accessibility of any kind isn’t funny to Derek or me or to anyone who can’t use the web without pain.
9. Watch your position
For example, if you lift up your arms to use the computer, or stare down at your laptop, you’ll need to rearrange your equipment. The internet has a lot of information about ideal ergonomic work areas. Please use a keyboard drawer. Be sure to measure the height carefully so that even a tented keyboard, like the one I recommend, will fit. I also recommend getting the version of the Freestyle with palm supports. Just these two measures did much to help both Jen Simmons and me.
10. If you need to take anti-inflammatories, stop working
If you are all drugged up on ibuprofen, and pounding and clicking like mad, your body will not know when you are tired or injuring yourself. I don’t recommend taking these while using your computing devices. Perhaps just take it at night, though I’m not a fan of that category of medications. Check with your healthcare provider. At least ibuprofen is an anti-inflammatory, which may help you. In contrast, acetaminophen (paracetamol) only makes your body think it’s not in pain. Ice is great, as is switching back and forth between ice and heat. But again, if you need ice and ibuprofen you really need to take a major break.
11. Don’t forget the rest of your body
I’ve zeroed in on my personal area of knowledge and experience, but you may be setting yourself up for problems in other areas of your body. There’s what is known to bad writers as “a veritable cornucopia” of information on the web about how to help the rest of your body. A wee bit of research on the web and you’ll discover simple exercises and stretches for the rest of your potential catastrophic areas: your upper back, your lower back, your legs, ankles, and eyes. Do gentle stretches, three or four times a day, rather than powering your way through. Ease into new equipment such as standing desks. Stretch those newly challenged areas until your body adapts. Pay attention to your body, even though I too often forget mine.
12. Remember the children
Kids are using equipment to play highly addictive games or to explore amazing software, and if these call for repetitive motions, children are being set up for future injuries. They’ll grab hold of something, as parents out there know, and play it 3,742 times. That afternoon. Perhaps by the time they are adults, everything will just be holograms and mind-reading, but adult fingers and hands are used for most things in life, not just computing devices and phones with keyboards sized for baby chipmunks.
I’ll be watching you
Quickly now, while I (possibly) have your attention. Don’t move a muscle. Is your neck tense? Are you unconsciously lifting your shoulders up? How long since you stopped staring at the screen? How bright is your screen? Are you slumping (c’mon now, ‘fess up) and inviting sciatica problems? Do you have to turn your hands at an angle relative to your wrist in order to type? Uh-oh. That’s a bad one. Your hands, wrists, and forearms should be one straight line while keyboarding. Future you is begging you to change your ways. Don’t let your #ThrowbackThursday in 2020 say, “Here’s a photo from when I used to be able to do so many wonderful things that I can’t do now.” And, whatever you do, don’t try for even a nanosecond to push through the pain, or the next thing you know, you’ll be an unpaid extra in The Expendables 7. |

What Is Vagrant and Why Should I Care? |
If you run a web server, a database server and your scripting language(s) of choice on your main machine and you have not yet switched to using virtualisation in your workflow then this essay may be of some value to you.
I know you exist because I bump into you daily: freelancers coming in to work on our projects; internet friends complaining about reinstalling a development environment because of an operating system upgrade; fellow agency owners who struggle to brief external help when getting a particular project up and running; or even hardcore back-end developers who “don’t do ops” and prefer to run their development stack of choice locally.
There are many perfectly reasonable arguments as to why you may not have already made the switch, from being simply too busy, all the way through to a distrust of the new. I’ll admit that there are many new technologies or workflows that I hear of daily and instantly disregard because I have tool overload, that feeling I get when I hear about a new shiny thing and think “Well, what I do now works – I’ll leave it for others to play with.” If that’s you when it comes to Vagrant then I hope you’ll hear me out. The business case is compelling enough for you to make that switch; as a bonus it’s also really easy to get going.
In this article we’ll start off by going through the high level, the tools available and how it all fits together. Then we’ll touch on the justification for making the switch, providing a few use cases that might resonate with you. Finally, I’ll provide a very simple example that you can follow to get yourself up and running.
What?
You already know what virtualisation is. You use the ability to run an operating system within another operating system every day. Whether that’s Parallels or VMware on your laptop or similar server-based tools that drive the ‘cloud’, squeezing lots of machines on to physical hardware and making it really easy to copy servers and even clusters of servers from one place to another. It’s an amazing technology which has changed the face of the internet over the past fifteen years.
Simply put, Vagrant makes it really easy to work with virtual machines. According to the Vagrant docs:
If you’re a designer, Vagrant will automatically set everything up that is required for that web app in order for you to focus on doing what you do best: design. Once a developer configures Vagrant, you don’t need to worry about how to get that app running ever again. No more bothering other developers to help you fix your environment so you can test designs. Just check out the code, vagrant up, and start designing.
While I’m not sure I agree with the implication that all designers would get others to do the configuring, I think you’ll agree that the “Just check out the code… and start designing” premise is very compelling.
You don’t need Vagrant to develop your web applications on virtual machines. All you need is a virtualisation software package, something like VMware Workstation or VirtualBox, and some code. Download the half-gigabyte operating system image that you want and install it. Then download and configure the stack you’ll be working with: let’s say Apache, MySQL, PHP. Then install some libraries, CuRL and ImageMagick maybe, and finally configure the ability to easily copy files from your machine to the new virtual one, something like Samba, or install an FTP server. Once this is all done, copy the code over, import the database, configure Apache’s virtual host, restart and cross your fingers.
If you’re a bit weird like me then the above is pretty easy to do and secretly quite fun. Indeed, the amount of traffic to one of my more popular blog posts proves that a lot of people have been building themselves development servers from scratch for some time (or at least trying to anyway), whether that’s on virtual or physical hardware.
Or you could use Vagrant. It allows you, or someone else, to specify in plain text how the machine’s virtual hardware should be configured and what should be installed on it. It also makes it insanely easy to get the code on the server. You check out your project, type vagrant up and start work.
Why?
It’s worth labouring the point that Vagrant makes it really easy; I mean look-no-tangle-of-wires-or-using-vim-and-loads-of-annoying-command-line-stuff easy to run a development environment.
That’s all well and good, I hear you say, but there’s a steep learning curve, an overhead to switch. You’re busy and this all sounds great but you need to get on; you’ve got a career to build or a business to run and you don’t have time to learn new stuff right now.
In short, what’s the business case?
The business case involves saved time, a very low barrier to entry and the ability to give the exact same environment to somebody else.
Getting your first development virtual machine running will take minutes, not counting download time. Seriously, use pre-built Vagrant files and provisioners (we’ll touch on this below) and you can start developing immediately.
Once you’ve finished developing you can check in your changes, ask a colleague or freelancer to check them out, and then they run the code on the exact same machine – even if they are on the other side of the world and regardless of whether they are on Windows, Linux or Apple OS X.
The configuration to build the machine isn’t a huge binary disk image that’ll take ages to download from Git; it’s two small text files that can be version controlled too, so you can see any changes made to the config and roll back if needed.
No more ‘It works for me’ reports; no ‘Oh, I was using PHP 5.3.3, not PHP 5.3.11’ – you’re both working on exact same copies of the development environment. With a tested and verified provisioning file you’ll have the confidence that when you brief your next freelancer in to your team there won’t be that painful to and fro of getting the system up and running, where you’re on a Skype call and they are uttering the immortal words, ‘It still doesn’t work’. You know it works because you can run it too.
This portability becomes even more important when you’re working on larger sites and systems. Need a load balancer? Multiple front-end servers and a clustered database back-end? No problem. Add each server into the same Vagrant file and a single command will build all of them. As you’ll know if you work on larger, business critical systems, keeping the operating systems in sync is a real problem: one server with a slightly different library causing sporadic and hard to trace issues is a genuine time black hole. Well, the good news is that you can use the same provisioning files to keep test and production machines in sync using your current build workflow.
Let’s also not forget the most simple use case: a single developer with multiple websites running on a single machine. If that’s you and you switch to using Vagrant-managed virtual machines then the next time you upgrade your operating system or do a fresh install there’s no chance that things will all stop working. The server config is all tucked away in version control with your code. Just pull it down and carry on coding.
OK, got it. Show me already
If you want to try this out you’ll need to install the latest VirtualBox and Vagrant for your platform. If you already have VMware Workstation or another supported virtualisation package installed you can use that instead but you may need to tweak my Vagrant file below. Depending on your operating system, a reboot might also be wise.
Note: the commands below were executed on my MacBook, but should also work on Windows and Linux. If you’re using Windows make sure to run the command prompt as Administrator or it’ll fall over when trying to update the hosts file.
As a quick sanity check let’s just make sure that we have the vagrant command in our path, so fire up a terminal and check the version number:
$ vagrant -v
Vagrant 1.6.5
We’ve one final thing to install and that’s the vagrant-hostsupdater plugin. Once again, in your terminal:
$ vagrant plugin install vagrant-hostsupdater
Installing the 'vagrant-hostsupdater' plugin. This can take a few minutes...
Installed the plugin 'vagrant-hostsupdater (0.0.11)'!
Hopefully that wasn’t too painful for you.
There are two things that you need to manage a virtual machine with Vagrant:
a Vagrant file: this tells Vagrant what hardware to spin up
a provisioning file: this tells Vagrant what to do on the machine
To save you copying and pasting I’ve supplied you with a simple example (ZIP) containing both of these. Unzip it somewhere sensible and in your terminal make sure you are inside the Vagrant folder:
$ cd where/you/placed/it/24ways
$ ls -l
-rw-r--r--@ 1 bealers staff 11055 9 Nov 09:16 bealers-24ways.md
-rw-r--r--@ 1 bealers staff 118152 9 Nov 10:08 it-works.png
drwxr-xr-x 5 bealers staff 170 8 Nov 22:54 vagrant
$ cd vagrant/
$ ls -l
-rw-r--r--@ 1 bealers staff 1661 8 Nov 21:50 Vagrantfile
-rwxr-xr-x@ 1 bealers staff 3841 9 Nov 08:00 provision.sh
The Vagrant file tells Vagrant how to configure the virtual hardware of your development machine. Skipping over some of the finer details, here’s what’s in that Vagrant file:
www.vm.box = "ubuntu/trusty64"
Use Ubuntu 14.04 for the VM’s OS. Vagrant will only download this once. If another project uses the same OS, Vagrant will use a cached version.
www.vm.hostname = "bealers-24ways.dev"
Set the machine’s hostname. If, like us, you’re using the vagrant-hostsupdater plugin, this will also get added to your hosts file, pointing to the virtual machine’s IP address.
www.vm.provider :virtualbox do |vb|
vb.customize ["modifyvm", :id, "--cpus", "2" ]
end
Here’s an example of configuring the virtual machine’s hardware on the fly. In this case we want two virtual processors.
Note: this is specific for the VirtualBox provider, but you could also have a section for VMware or other supported virtualisation software.
www.vm.network "private_network", ip: "192.168.13.37"
This specifies that we want a private networking link between your computer and the virtual machine. It’s probably best to use a reserved private subnet like 192.168.0.0/16 or 10.0.0.0/8
www.vm.synced_folder "../", "/var/www/24ways",
owner: "www-data", group: "www-data"
A particularly handy bit of Vagrant magic. This maps your local 24ways parent folder to /var/www/24ways on the virtual machine. This means the virtual machine already has direct access to your code and so do you. There’s no messy copying or synchronisation – just edit your files and immediately run them on the server.
www.vm.provision :shell, :path => "provision.sh"
This is where we specify the provisioner, the script that will be executed on the machine.
If you open up the provisioner you’ll see it’s a bash script that does things like:
install Apache, PHP, MySQL and related libraries
configure the libraries: set permissions, enable logging
create a database and grant some access rights
set up some code for us to develop on; in this case, fire up a vanilla WordPress installation
To get this all up and running you simply need to run Vagrant from within the vagrant folder:
$ vagrant up
You should now get a Matrix-like stream of stuff shooting up the screen. If this is the first time Vagrant has used this particular operating system image – remember we’ve specified the latest version of Ubuntu – it’ll download the disc image and cache it for future reuse. Then all the packages are downloaded and installed and finally all our configuration steps occur incluing the download and configuration of WordPress.
Halfway through proceedings it’s likely that the process will halt at a prompt something like this:
==> www: adding to (/etc/hosts) : 192.168.13.37 bealers-24ways.dev # VAGRANT: 2dbfbced1b1e79d2a0942728a0a57ece (www) / 899bd80d-4251-4f6f-91a0-d30f2d9918cc
Password:
You need to enter your password to give vagrant sudo rights to add the IP address and hostname mapping to your local hosts file.
Once finished, fire up your browser and go to http://bealers-24ways.dev. You should see a default WordPress installation. The username for wp-admin is admin and the password is 24ways.
If you take a look at your local filesystem the 24ways folder should now look like:
$ cd ../
$ ls -l
-rw-r--r--@ 1 bealers staff 13074 9 Nov 10:14 bealers-24ways.md
drwxr-xr-x 21 bealers staff 714 9 Nov 10:06 code
drwxr-xr-x 3 bealers staff 102 9 Nov 10:06 etc
-rw-r--r--@ 1 bealers staff 118152 9 Nov 10:08 it-works.png
drwxr-xr-x 5 bealers staff 170 9 Nov 10:03 vagrant
-rwxr-xr-x 1 bealers staff 1315849 9 Nov 10:06 wp-cli
$ cd vagrant/
$ ls -l
-rw-r--r--@ 1 bealers staff 1661 9 Nov 09:41 Vagrantfile
-rwxr-xr-x@ 1 bealers staff 3836 9 Nov 10:06 provision.sh
The code folder contains all the WordPress files. You can edit these directly and refresh that page to see your changes instantly.

Bonus level
The example I’ve provided isn’t very realistic. In the real world I’d expect the Vagrant file and provisioner to be included with the project and for it not to create the directory structure, which should already exist in your project. The same goes for the Apache VirtualHost file. You’ll also probably have a default SQL script to populate the database.
As you work with Vagrant you might start to find bash provisioning to be quite limiting, especially if you are working on larger projects which use more than one server. In that case I would suggest you take a look at Ansible, Puppet or Chef. We use Ansible because we like YAML but they all do the same sort of thing. The main benefit is being able to use the same Vagrant provisioning scripts to also provision test, staging and production environments using your build workflows.
Having to supply a password so the hosts file can be updated gets annoying very quicky so you can give Vagrant sudo rights:
$ sudo visudo
Add these lines to the bottom (Shift+G then i then Ctrl+V then Esc then :wq)
Cmnd_Alias VAGRANT_HOSTS_ADD = /bin/sh -c echo "*" >> /etc/hosts
Cmnd_Alias VAGRANT_HOSTS_REMOVE = /usr/bin/sed -i -e /*/ d /etc/hosts
%staff ALL=(root) NOPASSWD: VAGRANT_HOSTS_ADD, VAGRANT_HOSTS_REMOVE
Vagrant caches the operating system images that you download but it’ll download the installed software packages every time. You can get around this by using a plugin like vagrant-cachier or, if you’re really keen, maintain local Apt repositories (or whatever the equivalent is for your server architecture).
At some point you might start getting a large number of virtual machines running on your poor hardware all at the same time, especially if you’re switching between projects a lot and each of those projects use lots of servers. We’re just getting to that stage now, so are considering a medium-term move to a containerised option like Docker, which seems to be maturing now.
If you are keen not to use any command line tools whatsoever and you’re on OS X then you could check out Vagrant Manager as it looks quite shiny.
Finally, there are a huge amount of resources to give you pre-built Vagrant machines from the likes of VVV for Wordpress, something similar for Perch, PuPHPet for generating various configurations, and a long list of pre-built operating systems at VagrantBox.es.
Wrapping up
Hopefully you can now see why it might be worthwhile to add Vagrant to your development workflow. Whether you’re an agency drafting in freelancers or a one-person band running lots of sites on your laptop using MAMP or something similar.
Vagrant makes it easy to launch exact copies of the same machine in a repeatable and version controlled way. The learning curve isn’t too steep and, once configured, you can forget about it and focus on getting your work done. |

An Overview of SVG Sprite Creation Techniques |
SVG can be used as an icon system to replace icon fonts. The reasons why SVG makes for a superior icon system are numerous, but we won’t be going over them in this article. If you don’t use SVG icons and are interested in knowing why you may want to use them, I recommend you check out “Inline SVG vs Icon Fonts” by Chris Coyier – it covers the most important aspects of both systems and compares them with each other to help you make a better decision about which system to choose.
Once you’ve made the decision to use SVG instead of icon fonts, you’ll need to think of the best way to optimise the delivery of your icons, and ways to make the creation and use of icons faster.
Just like bitmaps, we can create image sprites with SVG – they don’t look or work exactly alike, but the basic concept is pretty much the same.
There are several ways to create SVG sprites, and this article will give you an overview of three of them. While we’re at it, we’re going to take a look at some of the available tools used to automate sprite creation and fallback for us.
Prerequisites
The content of this article assumes you are familiar with SVG. If you’ve never worked with SVG before, you may want to look at some of the introductory tutorials covering SVG syntax, structure and embedding techniques. I recommend the following:
SVG basics: Using SVG.
Structure: Structuring, Grouping, and Referencing in SVG — The <g>, <use>, <defs> and <symbol> Elements. We’ll mention <use> and <symbol> quite a bit in this article.
Embedding techniques: Styling and Animating SVGs with CSS. The article covers several topics, but the section linked focuses on embedding techniques.
A compendium of SVG resources compiled by Chris Coyier — contains resources to almost every aspect of SVG you might be interested in.
And if you’re completely new to the concept of spriting, Chris Coyier’s CSS Sprites explains all about them.
Another important SVG feature is the viewBox attribute. For some of the techniques, knowing your way around this attribute is not required, but it’s definitely more useful if you understand – even if just vaguely – how it works. The last technique mentioned in the article requires that you do know the attribute’s syntax and how to use it. To learn all about viewBox, you can refer to my blog post about SVG coordinate systems.
With the prerequisites in place, let’s move on to spriting SVGs!
Before you sprite…
In order to create an SVG sprite with your icons, you’ll of course need to have these icons ready for use.
Some spriting tools require that you place your icons in a folder to which a certain spriting process is to be applied. As such, for all of the upcoming sections we’ll work on the assumption that our SVG icons are placed in a folder named SVG.
Each icon is an individual .svg file.
You’ll need to make sure each icon is well-prepared and optimised for use – make sure you’ve cleaned up the code by running it through one of the optimisation tools or processes available (or doing it manually if it’s not tedious).
After prepping the icon files and placing them in a folder, we’re ready to create our SVG sprite.
HTML inline SVG sprites
Since SVG is XML code, it can be embedded inline in an HTML document as a code island using the <svg> element. Chris Coyier wrote about this technique first on CSS-Tricks.
The embedded SVG will serve as a container for our icons and is going to be the actual sprite we’re going to use. So we’ll start by including the SVG in our document.
<!DOCTYPE html>
<!-- HTML document stuff -->
<svg style="display:none;">
<!-- icons here -->
</svg>
<!-- other document stuff -->
</html>
Next, we’re going to place the icons inside the <svg>. Each icon will be wrapped in a <symbol> element we can then reference and use elsewhere in the page using the SVG <use> element. The <symbol> element has many benefits, and we’re using it because it allows us to define a symbol (which is a convenient markup for an icon) without rendering that symbol on the screen. The elements defined inside <symbol> will only be rendered when they are referenced – or called – by the <use> element.
Moreover, <symbol> can have its own viewBox attribute, which makes it possible to control the positioning of its content inside its container at any time.
Before we move on, I’d like to shed some light on the style="display:none;" part of the snippet above. Without setting the display of the SVG to none, and even though its contents are not rendered on the page, the SVG will still take up space in the page, resulting in a big empty area. In order to avoid that, we’re hiding the SVG entirely with CSS.
Now, suppose we have a Twitter icon in the icons folder. twitter.svg might look something like this:
<!-- twitter.svg -->
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" width="32" height="32" viewBox="0 0 32 32">

</svg>
We don’t need the root svg element, so we’ll strip the code and only keep the parts that make up the Twitter icon’s shape, which in this example is just the <path> element.Let’s drop that into the sprite container like so:
<svg style="display:none;">
<symbol id="twitter-icon" viewBox="0 0 32 32">
<path d="M32 6.076c-1.177 …" fill="#000000"></path>
</symbol>
<!-- remaining icons here -->
<symbol id="instagram-icon" viewBox="0 0 32 32">
<!-- icon contents -->
</symbol>
<!-- etc. -->
</svg>
Repeat for the other icons.
The value of the <symbol> element’s viewBox attribute depends on the size of the SVG. You don’t need to know how the viewBox works to use it in this case. Its value is made up of four parts: the first two will almost always be “0 0”; the second two will be equal to the size of the icon. For example, our Twitter icon is 32px by 32px (see twitter.svg above), so the viewBox value is “0 0 32 32”.
That said, it is certainly useful to understand how the viewBox works – it can help you troubleshoot SVG sometimes and gives you better control over it, allowing you to scale, position and even crop SVGs manually without having to resort to an editor. My blog post explains all about the viewBox attribute and its related attributes.
Once you have your SVG sprite ready, you can display the icons anywhere on the page by referencing them using the SVG <use> element:
<svg class="twitter-icon">
<use xlink:href="#twitter-icon"></use>
<svg>
And that’s all there is to it!
HTML-inline SVG sprites are simple to create and use, but when you have a lot of icons (and the more icon sets you create) it can easily become daunting if you have to manually transfer the icons into the <svg>. Fortunately, you don’t have to do that. Fabrice Weinberg created a Grunt plugin called grunt-svgstore which takes the icons in your SVG folder and generates the SVG sprites for you; all you have to do is just drop the sprites into your page and use the icons like we did earlier.
This technique works in all browsers supporting SVG. There seems to be a bug in Safari on iOS which causes the icons not to show up when the SVG sprite is defined at the bottom of the document after the <use> references to the icons, so it’s safest to include the sprite before you use the icons until this bug is fixed.
This technique has one disadvantage: the SVG sprite cannot be cached. We’re saving an extra HTTP request here but the browser cannot cache the image, so we aren’t speeding up any subsequent page loads by inlining the SVG. There must be a better way – and there is.
Styling the icons is possible, but getting deep into the styles becomes a bit harder owing to the nature of the contents of the <use> element – these contents are cloned into a shadow DOM, and hence selecting elements in CSS the traditional way is not possible. However, some techniques to work around that do exist, and give us slightly more styling flexibility. Animations work as expected.
Referencing an external SVG sprite in HTML
Instead of including the SVG inline in the document, you can reference the sprite and the icons inside it externally, taking advantage of fragment identifiers to select individual icons in the sprite.
For example, the above reference to the Twitter icon would look something like this instead:
<svg class="twitter-icon">
<use xlink:href="path/to/icons.svg#twitter-icon"></use>
<svg>
icons.svg is the name of the SVG file that contains all of our icons as symbols, and the fragment identifier #twitter-icon is the reference to the <symbol> wrapping the Twitter icon’s contents. Very convenient, isn’t it? The browser will request the sprite and then cache it, speeding up subsequent page loads. Win!
This technique also works in all browsers supporting SVG except Internet Explorer – not even IE9+ with SVG support permits this technique. No version of IE supports referencing an external SVG in <use>.
Fortunately (again), Jonathan Neil has created a plugin called svg4everybody which fills this gap in IE; you can reference an external sprite in <use> and also provide fallback for browsers that do not support SVG. However, it requires you to have the fallback images (PNG or JPEG, for example) available to do so. For details, refer to the plugin’s Github repository’s readme file.
CSS inline SVG sprites
Another way to create an SVG sprite is by inlining the SVG icons in a style sheet using data URIs, and providing fallback for non-supporting browsers – also within the CSS.
Using this approach, we’re turning the style sheet into the sprite that includes our icons. The style sheet is normally cached by the browser, so we have that concern out of the way.
This technique is put into practice in Filament Group’s icon system approach, which uses their Grunticon plugin – or its sister Grumpicon web app – for generating the necessary CSS for the sprite. As such, we’re going to cover this technique by following a workflow that uses one of these tools.
Again, we start with our icon SVG files. To focus on the actual spriting method and not on the tooling, I’ll go over the process of sprite creation using the Grumpicon web app, instead of the Grunticon plugin. Both tools generate the same resources that we’re going to use for the icon system. Whether you choose the web app or the Grunt set-up, after processing your SVG folder you’re going to end up with the same set of resources that we’ll be using throughout this section.
The first step is to drop your icons into the Grumpicon web app.
Grumpicon homepage screenshot.
The application will then show you a preview of your icons, and a download button will allow you to download the generated files. These files will contain everything you need for your icon system – all that’s left is for you to drop the generated files and code into your project as recommended and you’ll have your sprite and icons ready to use anywhere you want in your page.
Grumpicon generates five files and one folder in the downloaded package: a png folder containing PNG versions of your icons; three style sheets (that we’ll go over briefly); a loader script file; and preview.html which is a live example showing you the other files in action.
The script in the loader goes into the <head> of your page. This script handles browser and feature detection, and requests the necessary style sheet depending on browser support for SVG and base64 data URIs. If you view the source code of the preview page, you can see exactly how the script is added.
icons.data.svg.css is the style sheet that contains your icons – the sprite. The icons are embedded inline inside the style sheet using data URIs, and applied to elements of your choice as background images, using class names. For example:
.twitter-icon{
background-image: url('data:image/svg+xml;…'); /* the ellipsis is where the icon’s data would go */
background-repeat: no-repeat;
background-position: 50% 50%;
height: 2em;
width: 2em;
/* etc. */
}
Then, you only have to apply the twitter-icon class name to an element in your HTML to apply the icon as a background to it:
<span class="twitter-icon"></span>
And that’s all you need to do to get an icon on the page.
icons.data.svg.css, along with the other two style sheets and the png folder should be added to your CSS folder.
icons.data.png.css is the style sheet the script will load in browsers that don’t support SVG, such as IE8. Fallback for the inline SVG is provided as a base64-encoded PNG. For instance, the fallback for the Twitter icon from our example would look like so:
.twitter-icon{
background-image: url('data:image/png;base64;…’);
/* etc. */
}
icons.fallback.css is the style sheet required for browsers that don’t support base64-encoded PNGs – the PNG images are loaded as usual using the image’s URL. The script will load this style sheet for IE6 and IE7, for example.
.twitter-icon{
background-image: url(png/twitter-icon.png);
/* etc. */
}
This technique is very different from the previous one. The sprite in this case is literally the style sheet, not an SVG container, and the icon usage is very similar to that of a CSS sprite – the icons are provided as background images.
This technique has advantages and disadvantages. For the sake of brevity, I won’t go into further details, but the main limitations worth mentioning are that SVGs embedded as background images cannot be styled with CSS; and animations are restricted to those defined inside the <svg> for each icon. CSS interactions (such as hover effects) don’t work either. Thus, to apply an effect for an icon that changes its color on hover, for example, you’ll need to export a set of SVGs for each colour in order for Grumpicon to create matching fallback PNG images that can then be used for the animation.
For more details about the Grumpicon workflow, I recommend you check out “A Designer’s Guide to Grumpicon” on Filament Group’s website.
Using SVG fragment identifiers and views
This spriting technique is, again, different from the previous ones, and it is my personal favourite.
SVG comes with a standard way of cropping to a specific area in a particular SVG image. If you’ve ever worked with CSS sprites before then this definitely sounds familiar: it’s almost exactly what we do with CSS sprites – the image containing all of the icons is cropped, so to speak, to show only the one icon that we want in the background positioning area of the element, using background size and positioning properties.
Instead of using background properties, we’ll be using SVG’s viewBox attribute to crop our SVG to the specific icon we want.
What I like about this technique is that it is more visual than the previous ones. Using this technique, the SVG sprite is treated like an actual image containing other images (the icons), instead of treating it as a piece of code containing other code.
Again, our SVG icons are placed inside a main SVG container that is going to be our SVG sprite. If you’re working in a graphics editor, position or arrange your icons inside the canvas any way you want them to be, and then export the graphic as is. Of course, the less empty space there is in your SVG, the better.
In our example, the sprite contains three icons as shown in the following image. The sprite is open in Sketch. Notice how the SVG is just big enough to fit the icons inside it. It doesn’t have to be like this, but it’s cleaner this way.
Screenshot showing the SVG sprite containing our icons.
Now, suppose you want to display only the Instagram icon. Using the SVG viewBox attribute, we can crop the SVG to the icon. The Instagram icon is positioned at 64px along the positive x-axis, and zero pixels along the y-axis. It is also 32px by 32px in size.
Screenshot showing the position (offset) of the Instagram icon inside the SVG sprite, and its size.
Using this information, we can specify the value of the viewBox as: 64 0 32 32. This area of the view box contains only the Instagram icon. 64 0 specifies the top-left corner of the view box area, and 32 32 specify its dimensions.
Now, if we were to change the viewBox value on the SVG sprite to this value, only the Instagram icon will be visible inside the SVG viewport. Great. But how do we use this information to display the icon in our page using our sprite?
SVG comes with a native way to link to portions or areas of an image using fragment identifiers. Fragment identifiers are used to link into a particular view area of an SVG document. Thus, using a fragment identifier and the boundaries of the area that we want (from the viewBox), we can link to that area and display it.
For example, if you want to display the icon from the sprite using an <img> tag, you can reference the icon in the sprite like so:
<img src='uiIcons.svg#svgView(viewBox(64, 0, 32, 32))' alt="Settings icon"/>
The fragment identifier in the snippet above (#svgView(viewBox(64, 0, 32, 32))) is the important part. This will result in only the Instagram icon’s area of the sprite being displayed.
There is also another way to do this, using the SVG <view> element. The <view> element can be used to define a view area and then reference that area somewhere else. For example, to define the view box containing the Instagram icon, we can do the following:
<view id='instagram-icon' viewBox='64 0 32 32' />
Then, we can reference this view in our <img> element like this:
<img src='sprite.svg#instagram-icon' alt="Instagram icon" />
The best part about this technique – besides the ability to reference an external SVG and hence make use of browser caching – is that it allows us to use practically any SVG embedding technique and does not restrict us to specific tags.
It goes without saying that this feature can be used for more than just icon systems, owing to viewBox’s power in controlling an SVG’s viewable area.
SVG fragment identifiers have decent browser support, but the technique is buggy in Safari: there is a bug that causes problems when loading a server SVG file and then using fragment identifiers with it. Bear Travis has documented the issue and a workaround.
Where to go from here
Pick the technique that works best for your project. Each technique has its own pros and cons, relating to convenience and maintainability, performance, and styling and scripting. Each technique also requires its own fallback mechanism.
The spriting techniques mentioned here are not the only techniques available. Other methods exist, such as SVG stacks, and others may surface in future, but these are the three main ones today.
The third technique using SVG’s built-in viewBox features is my favourite, and with better browser support and fewer (ideally, no) bugs, I believe it is more likely to become the standard way to create and use SVG sprites. Fallback techniques can be created, of course, in one of many possible ways.
Do you use SVG for your icon system? If so, which is your favourite technique? Do you know or have worked with other ways for creating SVG sprites? |

Content Production Planning |
While everyone agrees that getting the content of a website right is vital to its success, unless you’re lucky enough to have an experienced editor or content strategist on board, planning content production often seems to fall through the cracks. One reason is that, for most of the team, it feels like someone else’s problem. Not necessarily a specific person’s problem. Just someone else’s. It’s only when everyone starts urgently asking when the content is going to be ready, that it becomes clear the answer is, “Not as soon as we’d like it”.
The good news is that there are some quick and simple things you can do, even if you’re not the official content person on a project, to get everyone on the same content planning page.
Content production planning boils down to answering three deceptively simple questions:
What content do you need?
How much of it do you need?
Who’s going to make it?
Even if it’s not your job to come up with the answers, by asking these questions early enough and agreeing who is going to come up with the answers, you’ll be a long way towards avoiding the last-minute content problems which so often plague projects.
How much content do we need?
People tend to underestimate two crucial things about content: how much content they need, and how long that content takes to produce.
When I ask someone how big their website is – how many pages it contains – I usually double or triple the answer I get. That’s because almost everyone’s mental model of their website greatly underestimates its true size. You can see the problem for yourself if you look at a site map. Site maps are great at representing a mental model of a website. But because they’re a deliberate simplification they naturally lead us to underestimate how much content is involved in populating them.
Several years ago I was asked to help a client create a new microsite (their word) which they wanted ready in two weeks for a conference they were attending. Here’s the site map they had in mind. At first glance it looks like a pretty small website. Maybe twenty to thirty pages?
That’s what the client thought.
But see those boxes which are multiple boxes stacked on top of one another, for product categories, descriptions and supporting material? They’re known as page stacks, and page stacks are the content strategy equivalent of Here Be Dragons.
Say we have:
five product categories
each with five products
which all have two or three supporting documents
Those are still fairly small numbers. But small numbers multiplied by other small numbers tend to lead to big numbers.
5 categories = 5 category descriptions
plus
5 categories × 5 products each = 25 product descriptions
plus
25 products × 2.5 (average) supporting documents = 63 supporting documents
equals
93 pages
Suddenly our twenty- or thirty-page website is running towards one hundred.
That’s probably enough to get most project teams to sit up and take notice. But there’s still the danger of underestimating how long it’s going to take to create the content. After all, assuming the supporting documents already exist in some form, there are only about twenty-five to thirty pages of new copy to write.
How much work is it?
Again, we have the problem that small numbers when multiplied by other small numbers tend to lead to big numbers. Let’s make a rough guess that it’ll take four hours to write each product category and description page we need. That feels a little conservative if we’re writing stuff from scratch, but assuming the person doing it already knows the products fairly well it’s not unreasonable.
30 pages × 4 hours each = 120 hours
120 hours ÷ 7.5 working hours a day = 16 days
Ouch.
At this point it’s pretty clear we’re not getting this site launched in two weeks.
The goal is the conversation
By breaking down the site into its content components, and putting some rough estimates on how long each might take to produce, the client instantly realised that there was no way they would be ready to launch it in two weeks. Although we still didn’t know exactly when it would be ready, getting to that realisation right at the start of the project was a major win for everybody. Without it, the design agency would have bust a gut to get the design, front-end and CMS all done in double-quick time, only to find it was all for nothing as barely half the content was ready. As it was, an early discussion about content, albeit a brief one, bought everyone time to tackle the project properly, without pulling any long nights or working weekends.
If you haven’t been able to get people to discuss content plans for the project, these kinds of rough estimates should give you enough evidence to get everyone to start taking it seriously. Your goal is to get everyone on the project to a place where they are ready to talk in detail about who is going to create this content, and how long it’s really going to take them, and to get to those conversations before lack of content becomes a problem.
Be careful though. It’s best to talk in ranges and round numbers when your estimates are this uncertain. And watch those multipliers. Given small numbers multiplied by other small numbers lead to big numbers, changing just one number can greatly change the overall estimate. I like to run a couple of different scenarios to check what things look like if I’ve under- or overestimated either how many pages we’re going to need, or how long they’re going to take to create. For example:
Top end: 30 pages × 5 hours = 150 hours, or 20 days
Bottom end: 25 pages × 4 hours = 100 hours, or 13.3 days
So rather than say, “I estimate the content will take around sixteen days to produce”, I’m going to say, “I think the content will take about three to four weeks to produce”. Even with qualifiers like estimate and around, sixteen days sounds too precise. Whereas three to four weeks instantly conveys that this is just a rough figure.
Who’s going to make it?
So, people tend to underestimate two crucial things about content: how much content they need, and how long content takes to write. At this stage, you’re still in danger of the latter, because it’s tempting to simply estimate how much time content takes to write (or record, if we’re talking audio or visual content), and overlook all the other work that needs to goes on around it.
Take 24 ways as an example. In terms of our three deceptively simple questions: what is practical articles about web design; how many is twenty-four, one for each day of Advent; and who are experts working on the web, one to write each article.
But there’s another who you might not have considered.
Someone needs to select those authors in the first place, make sure they deliver their articles on time (and find someone to replace them if they don’t), review drafts, copy-edit and proofread final versions, upload them to the site, promote them, keep an eye on the comments and make sure there are still presents under the tree on Christmas morning.
Even if each of those tasks only takes an hour or so, it then needs multiplying by twenty-four (except the presents, obviously). And as we’ve already seen, small numbers multiplied by small numbers quickly turn into much bigger numbers. Just a few hours per article, when multiplied by twenty-four articles, easily multiplies up to days or even weeks of effort.
To get a more accurate estimate of how long the different kinds of content are going to take, you need to break down the content production work into its constituent stages, starting with planning, moving on through the main work of creation, to reviewing, approvals and finally publishing. You need to think about who needs to be involved at each step, and how much time they’ll need to do their bit.
Taken together, these things make up your content workflow. The workflow will be different for each organisation, but might look something like this:
Eddie the web editor will work out the key messages and objectives for each page, and agree them with Mo the marketing director.
Eddie will then get Cal, the copywriter, to write the first draft.
As part of that, Cal will interview Sam the subject expert to understand the intricacies of the subject and get all the facts straight.
Once Cal’s done the first draft, it’ll go to Sam to check for accuracy, while Eddie reviews it for style and message.
Once Cal has incorporated their feedback it’s time to get Mo to have a look at the final draft.
If Mo’s happy, it’ll get a final proofread, be uploaded to the CMS, and Mo will give the final sign-off and release it for publishing.
You can plot this on a table, with the stages of the content production process down the side, and the key roles or personnel along with top. Then the team can estimate how much time they think each of them needs at each stage.

You can then bring out your calculator again, and come up with some more big scary numbers showing how much time it’s going to take for the whole team to get all the content needed not just written, but also planned, reviewed, approved and published.
With an experienced team you can run this exercise as a group workshop and get some fairly accurate estimates pretty quickly. If this is all a bit new to you, check out Gather Content’s Content Production Planning for Agencies ebook for a useful guide to common content roles, ballpark estimates for how much time each one needs on a typical piece of content, and how to run a process and estimating workshop to dig into them in more detail.
On a small team, one person might play many roles, but you should still sanity-check your estimates by breaking down the process and putting a rough estimate on each stage. With only a couple of people involved, it’s even easier to only include the core activity like writing or recording in your estimates, and forget to allow time for the planning, reviewing, proofreading, publishing and promoting you’ll still need to do. And even in a team of one, if at all possible you should find at least one other person to act as a second pair of eyes, and give anything you produce a quick once-over and proofread before it’s published.
Depending on the kind of content you’re making, you should also consider what will happen after it’s published. The full content life cycle should include promotion, monitoring and regular reviews to make sure content stays accurate and up to date. Making sure you have the time and resources available to do all those things for each piece of content is essential for creating a sustainable content programme.
The proof of the pudding
Even after digging into workflow and getting the whole team involved in estimating, you’re still largely in the realm of the guesstimate. The good news, though, is that you can quite quickly start finding out if your guesstimates are right or not. As soon as you can, pilot the production process with some real content. This is a double-win: you start finding out how long it really takes to produce all this fab new content, and you get real content to work with in designs and prototypes.
Once you’ve run a few things through your process, you’ll be able to refine your estimates, confirm your workflow, and give everyone involved a clear idea of when it will all be ready, and what you need from them.
Keeping it all on track
At this point I like to pull everything together into the content strategist’s favourite tool: the spreadsheet.
A simple content production checklist is a bit like a content inventory or audit, but for the content you don’t yet have, not the stuff already done. You can grab an example here.
Each piece of content gets its own row, with columns for basic information like page title, ID (which should match the site map), and who’s responsible for making it. You can capture simple details like target audience and key messages here too, though for more complex content, page description tables like those described by Relly Annett-Baker in “Extracting the Content” may be a better tool to use. Just adapt these columns to whatever makes sense for your content.
I then have columns to track where each piece is in the production process. I usually keep this simple, with a column each to mark whether it’s draft, final or uploaded. The status column on the left automatically shows the item’s status, using a simple traffic light colour scheme for whether the item is still to do (red), in draft (amber), or done (green). Seeing the whole thing slowly turn from red to green is a nice motivator.
If you want to track the workflow in more detail, a kanban board in a tool like Trello is a great way for a team to collaborate on content production, track each item’s progress, and keep an eye out for bottlenecks and delays.
Getting to the content strategy conversation
It’s a relatively simple exercise, then, to decide not just what kinds of pages you need, but also how many of them: put some rough estimates of effort on the tasks needed to create those pages – not just the writing, but all the other stages of planning, reviewing, approving, publishing and promoting – and then multiply all those things together. This will quickly bring some reality to grand visions and overambitious plans. Do it early enough, and even when the final big scary number is a lot bigger and scarier than everyone thought, you’ll still have time to do something about it.
As well as getting everyone on board for some proper content planning activities, that big scary number is your opportunity to get to the real core questions of content strategy: do we really need all this content? Where can existing content be reused and repurposed? How do we prioritise our efforts? What really matters to our readers and users?
Time and again, case studies show that less content delivers more: more leads, more sales, more self-service support and savings in the call centre. Although that argument is primarily one you should make from a good-for-the-users perspective, it doesn’t hurt to be able to make it from the cheaper-for-the-business perspective as well, and to have some big scary numbers to back that up. |

Taglines and Truisms |
To bring her good luck, “white rabbits” was the first thing that my grandmother said out loud on the first day of every month. We all need a little luck, but we shouldn’t rely on it, especially when it comes to attracting new clients.
The first thing we say to a prospective client when they visit our website for the first time helps them to understand not only what we do but why we do it. We can also help them understand why they should choose to work with us over one of our competitors.
Take a minute or two to look at your competitors’ websites. What’s the first thing that they say about themselves? Do they say that they “design delightful digital experiences,” “craft beautiful experiences” or “create remarkable digital experiences?”
It’s easy to find companies who introduce themselves with what they do, their proposition, but what a company does is only part of their story. Their beliefs and values, what they stand for why they do what they do are also important.
When someone visits our websites for the first time, we have only a brief moment to help them understand us. To help us we can learn from the advertising industry, where the job of a tagline is to communicate a concept, deliver a message and sell a product, often using only a few words.
When an advertising campaign is effective, its tagline stays with you, sometimes long after that campaign is over. For example, can you remember which company or brand these taglines help to sell? (Answers at the bottom of the article:)
The Ultimate Driving Machine
Just Do It
Don’t Leave Home Without It
A clever tagline isn’t just a play on words, although it can include one. A tagline does far more than help make your company memorable. Used well, it brings together notions of what makes your company and what you offer special. Then it expresses those notions in a few words or possibly a short sentence.
I’m sure that everyone can find examples of company slogans written in the type of language that should stay within the walls of a marketing department. We can also find taglines where the meaning is buried so deep that the tag itself becomes effectively meaningless.
A meaningful tagline supports our ideas about who we are and what we offer, and provides a platform for different executions of them, sometimes over a period of time. For a tagline to work well, it must allow for current and future ideas about a brand.
It must also be meaningful to our brand and describe a truism, a truth that need not be a fact or statistic, but something that’s true about us, who we are, what we do and why that’s distinctive. It can be obvious, funny, serious or specific but above all it must be true. It should also be difficult to argue with, making your messages difficult to argue with too.
I doubt that I need remind you who this tagline belongs to:
There are some things money can’t buy. For everything else there’s MasterCard.
That tagline was launched in 1997 by McCann-Erickson along with the “Priceless” campaign and it helped establish MasterCard as a friendlier credit card company, one with a sense of humour.
MasterCard’s truism is that the things which really matter in life can’t be bought. They are worth more than anything that a monetary value can be applied to. In expressing that truism through the tagline, MasterCard’s advertising tells people to use not just any credit card, but their MasterCard, to pay for everything they buy.
“Guinness is good for you” may have been a stretch, but “Good things come to those who wait” builds on the truism that patience is a virtue and therefore a good pint of Guinness takes time to pour (119.5 seconds. I know you were wondering.)
The fact that British Airways flies to more destinations than any other airline is their truism, and led their advertisers to the now famous tagline, “The world’s favourite airline.”
At my company, Stuff & Nonsense, we’ve been thinking about taglines as we think about our position within an industry that seems full of companies who “design”, “craft”, and “create” “delightful”, “beautiful”, “remarkable digital experiences”.
Much of what made us different has changed along with the type of work we’re interested in doing. Our work’s expanded beyond websites and now includes design for mobile and other media. It’s true we can’t know how or where it will be seen. The ways that we make it are flexible too as we’re careful not to become tied to particular tools or approaches.
It’s also true that we’re a small team. One that’s flexible enough to travel around the world to work alongside our clients. We join their in-house teams and we collaborate with them in ways that other agencies often find more difficult. We know that our clients appreciate our flexibility and have derived enormous value from it. We know that we’ve won business because of it and that it’s now a big part of our proposition.
Our truism is that we’re flexible, “Fabulously flexible” as our tagline now expresses. And although we know that there may be other agencies who can be similarly flexible – after all, being flexible is not a unique selling proposition – only we do it so fabulously.
As the old year rolls into the new, how will your company describe what you do in 2015? More importantly, how will you tell prospective clients why you do it, what matters to you and why they should work with you?
Start by writing a list of truisms about your company. Write as many as you can, but then whittle that list down to just one, the most important truth. Work on that truism to create a tagline that’s meaningful, difficult to be argue with and, above all, uniquely yours.

Is Agile Harder for Agencies? |
I once sat in a pitch meeting and watched a new business exec tell a potential client that his agency followed an agile workflow process at all times. The potential client nodded wisely, and they both agreed that agile was indeed the way to go.
The meeting progressed and they signed off on a contract for a massive project, to be delivered in a standard waterfall fashion, with all manner of phases and key deliverables.
Of course both of them left the meeting perfectly happy, because neither of them knew nor cared what an agile workflow process might be.
That was about five years ago. As 2015 heaves into view I think it’s fair to say that attitudes have changed. Perhaps the same number of people claim to do Agile™ now as in 2010, but I think more of them are telling the truth.
As a developer in an agency that works primarily with larger organisations, this year I have started to see a shift from agencies pushing agile methodologies with their clients, to clients requesting and even demanding agile practices from their agencies. Only a couple of years ago this would have been unusual behaviour.
So what’s the problem?
We should be happy then, no? Those of us in agencies will get to spend more time delivering great products, and less time arguing over out-of-date functional specs or battling through an adversarial change management procedure because somebody had a good idea during development rather than planning. We get to be a little bit more like our brothers and sisters in vaunted teams like the Government Digital Service, which is using agile approaches to great effect on projects that have a real benefit to their users.
Almost. Unfortunately, it seems to be the case that adhering to an agile framework such as scrum is more difficult within an agency/client structure than it is for an in-house development team.
This is no surprise. The Agile Manifesto was written in 2001 by a group of software developers for their own use. Many of the underlying principles of a framework like Scrum assume the existence of an in-house team, working on a highly technical project, and working for the business that employs them. The agency/client model must to some extent be retrofitted into agile frameworks. It can be done though, and there are plenty of agencies out there doing it well.
This article isn’t meant to be another introduction to agile techniques – there are too many of those online already. This article is for people just dipping their toes into this way of working. I’ve laid out a few of the key reasons why adopting a more fully agile approach seems difficult, at least initially, for those of us working in agencies.
1. Agile asks more of your clients
When a team adopts Scrum everyone has to get used to a number of unfamiliar roles and rituals. Few team members have a steeper learning curve than the person designated as the product owner.
The product owner carries a lot of weight on their shoulders. They have to uphold the overall vision for the project. They are also meant to be the primary author of the project’s user stories (short atomic descriptions of project features which are testable and relate to a real business need). They should own this list of stories (called a backlog) and should be able to prioritise the order in which the stories are developed, to ensure that the project is delivering real value to the business early and often.
When a burst of work is completed (bursts of work in Scrum are called sprints), the product owner leads a review or show-and-tell session with the wider project stakeholders. The product owner needs to understand the work that has been completed, and must champion it to the business. Finally, and most importantly, the product owner is responsible for managing the feedback and requests from stakeholders in such a way that they don’t derail the project team’s agreed workload for any given sprint, without upsetting or offending any of the stakeholders – some of whom may outrank the product owner.
If you follow that spec, this is a job for a superhuman in any organisational context. And within the agency/client structure this superhuman needs to be client-side for the process to be at its most effective.
So your client, who in the past might have briefed a project to an agency team and then had the work presented back to them every few weeks, is now asked to be involved with the team on a daily basis; to fight on behalf of the team when new or difficult requests come in from senior figures within their organisation; and to present the agency’s work to their own colleagues after each sprint. It’s a big change if all that gets dropped into someone’s lap without warning.
There are several ways agencies can mitigate this issue. The ScrumAlliance suggests some alternative ways to structure the product owner role. The approach I have taken in the past is simply to start slow, and gradually move more of the product owner role over to the client side as and when they feel comfortable with it. If you’re working together long-term on a project, and you both see tangible improvements in the quality of the work after adopting an agile process, then your client is more likely to be open to further changes as the partnership progresses.
2. My client wants fixed costs, fixed deadlines and a fixed scope
I know. Mine too. Of course they do – it is the way that agencies and clients have agreed to work in digital and other creative service industries for a very long time. On both sides of the fence we’re used to thinking about projects in this way.
Of the three, fixing scope is the one that agile purists would rail hardest against. The more time we spend working on digital projects, the less sense it makes. James Archer, CEO of UI/UX design agency Forty puts it like this:
For me, the Agile approach is really about acknowledging that disturbing truth that every project manager knows, but has trouble admitting. The truth that the project plan is wrong. Scope creep. Change orders. Shifting priorities. New directions. We act shocked and appalled when those things happen during our carefully planned project, even though they happen on every project ever.
Successful relationships require trust and honesty, and we shouldn’t be afraid of discussing this aspect of project management. If you do move away from a fixed scope of work, then the other two items (costs and timings) can be fixed – more or less. If you can get your clients to buy into this from a standing start then you are doing well. In fact you probably deserve a promotion. For most of us this is a continual discussion.
Anyway, as soon as you’ve made headway on the argument that it makes little or no sense to try and fix the scope of a digital project, you usually run into a related concern, which we’ll look at next.
3. Fear of uncontrolled costs
We all know that a dog is for life, not just for Christmas. At this time of year perhaps we should reiterate to everyone that digital products and services also need support and love once we have taken the decision to bring them into the world.
More organisations are realising that their investment in digital platforms should be viewed as an operational expenditure rather than a capital expenditure. But from time to time we will find ourselves working on projects for people who have a finite amount of money to invest in a product at a given point in time. When agencies start talking about these projects as rolling investments those responsible can understandably worry about their costs running out of control.
There’s another factor at play here. Agile, on the whole, prefers to derive a cost for services from the hours a team spends working on a project. In other industries this is referred to as charging for time and materials, and there seems to be an ingrained distrust in this approach among people in general. See, for example, the Citizens Advice Bureau’s “Top tips for employing a builder”:
“Bear in mind that if you pay a daily rate, this makes it easier for a builder to string the work out and get more money so agree what you will do if the job takes longer than expected.”
It’s hard not to feel stung if you are in the builder’s shoes here, as we are when we’re talking about our role as an agency. But if you’ve ever haggled with a builder over time and materials, and also moaned about your clients misunderstanding agile methods, take a moment to reflect on the similarities from your client’s point of view.
Again, there are some things we can do to mitigate this issue. Some agencies put in place a service level agreement around their team’s velocity (an agile-related term related to how much work a team delivers in any given sprint) and this can help.
As the industry moves further towards a long-term approach to investment in digital I hope this fear will subside. But that shift in approach leads to the final concern I want to address.
4. Agency structures need shaking up
If you work for a company that has spent many years developing a business model around the waterfall process, you may have to break through many layers of entrenched thinking in order to establish new practices and effect organisational change.
There are consultancies that exist specifically to help agencies through their own agile transformation. One of these companies, AgencyAgile, provides a helpful list of common pitfalls. They emphasise the need to look at your whole agency’s structure, rather than simply encouraging project teams to adopt new workflows.
Even awesomely run Agile projects can have a limited impact on the overall organization.
If you’re serious about changing the way your company approaches projects then try talking to people who sit outside the usual project delivery team. Speak to the finance department if you have one, and try to convince your senior management team if they’re not already on board. And definitely speak to your new business people, who go out there and win the projects you get to work on.
It’s these people who need to understand the potential business benefits of working in a new way, and also which of their existing habits and behaviours they might need to change to accommodate a new approach.
Otherwise you’ll find yourself with a team of designers, developers and project managers who are ready and waiting to deliver work in an iterative and collaborative way, but by the time they get hold of the project a cost has already been agreed, a deadline has been imposed, and a functional requirements document has been painstakingly put together. Nobody wins in this situation.
Conclusion
So where should we go from here? I certainly don’t have hard and fast answers – I’m not sure that they exist in a one-size-fits-all approach for agencies.
There are plenty of smart people thinking about this problem. It’s a hot topic right now. Earlier in the year a London-based meetup was established called Agile for Agencies. If you’re in the capital and want to discuss these issues with your peers it’s a great opportunity to do so.
I’ve mentioned James Archer and Forty already. Both James and Paul Boag have written in the last twelve months on this subject. They both come out on the side of the argument that suggests you adopt agile principles, but don’t have to worry about the rituals if they don’t fit in with your practices.
Personally, I think the rituals and the discipline mandated by an agile framework like Scrum can provide a great deal of value to your team, even it if is hard to implement within an agency culture that has traditionally structured its work and its services in another way.
In whatever way you figure out the details, when your teams collaborate with your clients rather than work for them at arm’s length, and when everyone prioritises frequent delivery, reflection and iteration over exhaustive scoping and planning, I believe you’ll see a tangible difference in the quality of the work that you create. |

Responsive Enhancement |
24 ways has been going strong for ten years. That’s an aeon in internet timescales. Just think of all the changes we’ve seen in that time: the rise of Ajax, the explosion of mobile devices, the unrecognisably changed landscape of front-end tooling.
Tools and technologies come and go, but one thing has remained constant for me over the past decade: progressive enhancement.
Progressive enhancement isn’t a technology. It’s more like a way of thinking. Instead of thinking about the specifics of how a finished website might look, progressive enhancement encourages you to think about the fundamental meaning of what the website is providing. So instead of thinking of a website in terms of its ideal state in a modern browser on a nice widescreen device, progressive enhancement allows you to think about the core functionality in a more abstract way.
Once you’ve figured out what the core functionality is – adding an item to a shopping cart, posting a message, sharing a photo – then you can enable that functionality in the simplest possible way. That usually means starting with good old-fashioned HTML. Links and forms are often all you need. Then, once you have the core functionality working in a basic way, you can start to enhance to make a progressively better experience for more modern browsers.
The advantage of working this way isn’t just that your site will work in older browsers (albeit in a rudimentary way). It also ensures that if anything goes wrong in a modern browser, it won’t be catastrophic.
There’s a common misconception that progressive enhancement means that you’ll spend your time dealing with older browsers, but in fact the opposite is true. Putting the basic functionality into place doesn’t take very long at all. And once you’ve done that, you’re free to spend all your time experimenting with the latest and greatest browser technologies, secure in the knowledge that even if they aren’t universally supported yet, that’s OK: you’ve already got your fallback in place.
The key to thinking about web development this way is realising that there isn’t one final interface – there could be many, slightly different interfaces depending on the properties and capabilities of any particular user agent at any particular moment. And that’s OK. Websites do not need to look the same in every browser.
Once you truly accept that, it’s an immensely liberating idea. Instead of spending your time trying to make websites look the same in wildly varying browsers, you can spend your time making sure that the core functionality of what you build works everywhere, while providing the best possible experience for more capable browsers.
Allow me to demonstrate with a simple example: navigation.
Step one: core functionality
Let’s say we have a straightforward website about the twelve days of Christmas, with a page for each day. The core functionality is pretty clear:
To read about any particular day.
To browse from day to day.
The first is easily satisfied by marking up the text with headings, paragraphs and all the usual structural HTML elements. The second is satisfied by providing a list of good ol’ hyperlinks.
Now where’s the best place to position this navigation list? Personally, I’m a big fan of the jump-to-footer pattern. This puts the content first and the navigation second. At the top of the page there’s a link with an href attribute pointing to the fragment identifier for the navigation.
<body>
<main role="main" id="top">
<a href="#menu" class="control">Menu</a>
...
</main>
<nav role="navigation" id="menu">
...
<a href="#top" class="control">Dismiss</a>
</nav>
</body>
See the footer-anchor pattern in action.
Because it’s nothing more than a hyperlink, this works in just about every browser since the dawn of the web. Following hyperlinks is what web browsers were made to do (hence the name).
Step two: layout as an enhancement
The footer-anchor pattern is a particularly neat solution on small-screen devices, like mobile phones. Once more screen real estate is available, I can use the magic of CSS to reposition the navigation above the content. I could use position: absolute, flexbox or, in this case, display: table.
@media all and (min-width: 35em) {
.control {
display: none;
}
body {
display: table;
}
[role="navigation"] {
display: table-caption;
columns: 6 15em;
}
}
See the styles for wider screens in action
Step three: enhance!
Right. At this point I’m providing core functionality to everyone, and I’ve got nice responsive styles for wider screens. I could stop here, but the real advantage of progressive enhancement is that I don’t have to. From here on, I can go crazy adding all sorts of fancy enhancements for modern browsers, without having to worry about providing a fallback for older browsers – the fallback is already in place.
What I’d really like is to provide a swish off-canvas pattern for small-screen devices. Here’s my plan:
Position the navigation under the main content.
Listen out for the .control links being activated and intercept that action.
When those links are activated, toggle a class of .active on the body.
If the .active class exists, slide the content out to reveal the navigation.
Here’s the CSS for positioning the content and navigation:
@media all and (max-width: 35em) {
[role="main"] {
transition: all .25s;
width: 100%;
position: absolute;
z-index: 2;
top: 0;
right: 0;
}
[role="navigation"] {
width: 75%;
position: absolute;
z-index: 1;
top: 0;
right: 0;
}
.active [role="main"] {
transform: translateX(-75%);
}
}
In my JavaScript, I’m going to listen out for any clicks on the .control links and toggle the .active class on the body accordingly:
(function (win, doc) {
'use strict';
var linkclass = 'control',
activeclass = 'active',
toggleClassName = function (element, toggleClass) {
var reg = new RegExp('(s|^)' + toggleClass + '(s|$)');
if (!element.className.match(reg)) {
element.className += ' ' + toggleClass;
} else {
element.className = element.className.replace(reg, '');
}
},
navListener = function (ev) {
ev = ev || win.event;
var target = ev.target || ev.srcElement;
if (target.className.indexOf(linkclass) !== -1) {
ev.preventDefault();
toggleClassName(doc.body, activeclass);
}
};
doc.addEventListener('click', navListener, false);
}(this, this.document));
I’m all set, right? Not so fast!
Cutting the mustard
I’ve made the assumption that addEventListener will be available in my JavaScript. That isn’t a safe assumption. That’s because JavaScript – unlike HTML or CSS – isn’t fault-tolerant. If you use an HTML element or attribute that a browser doesn’t understand, or if you use a CSS selector, property or value that a browser doesn’t understand, it’s no big deal. The browser will just ignore what it doesn’t understand: it won’t throw an error, and it won’t stop parsing the file.
JavaScript is different. If you make an error in your JavaScript, or use a JavaScript method or property that a browser doesn’t recognise, that browser will throw an error, and it will stop parsing the file. That’s why it’s important to test for features before using them in JavaScript. That’s also why it isn’t safe to rely on JavaScript for core functionality.
In my case, I need to test for the existence of addEventListener:
(function (win, doc) {
if (!win.addEventListener) {
return;
}
...
}(this, this.document));
The good folk over at the BBC call this kind of feature test cutting the mustard. If a browser passes the test, it cuts the mustard, and so it gets the enhancements. If a browser doesn’t cut the mustard, it doesn’t get the enhancements. And that’s fine because, remember, websites don’t need to look the same in every browser.
I want to make sure that my off-canvas styles are only going to apply to mustard-cutting browsers. I’m going to use JavaScript to add a class of .cutsthemustard to the document:
(function (win, doc) {
if (!win.addEventListener) {
return;
}
...
var enhanceclass = 'cutsthemustard';
doc.documentElement.className += ' ' + enhanceclass;
}(this, this.document));
Now I can use the existence of that class name to adjust my CSS:
@media all and (max-width: 35em) {
.cutsthemustard [role="main"] {
transition: all .25s;
width: 100%;
position: absolute;
z-index: 2;
top: 0;
right: 0;
}
.cutsthemustard [role="navigation"] {
width: 75%;
position: absolute;
z-index: 1;
top: 0;
right: 0;
}
.cutsthemustard .active [role="main"] {
transform: translateX(-75%);
}
}
See the enhanced mustard-cutting off-canvas navigation. Remember, this only applies to small screens so you might have to squish your browser window.
Enhance all the things!
This was a relatively simple example, but it illustrates the thinking behind progressive enhancement: once you’re providing the core functionality to everyone, you’re free to go crazy with all the latest enhancements for modern browsers.
Progressive enhancement doesn’t mean you have to provide all the same functionality to everyone – quite the opposite. That’s why it’s key to figure out early on what the core functionality is, and make sure that it can be provided with the most basic technology. But from that point on, you’re free to add many more features that aren’t mission-critical. You should reward more capable browsers by giving them more of those features, such as animation in CSS, geolocation in JavaScript, and new input types in HTML.
Like I said, progressive enhancement isn’t a technology. It’s a way of thinking. Once you start thinking this way, you’ll be prepared for whatever the next ten years throws at us. |

Developing Robust Deployment Procedures |
Once you have developed your site, how do you make it live on your web hosting? For many years the answer was to log on to your server and upload the files via FTP. Over time most hosts and FTP clients began to support SFTP, ensuring your files were transmitted over a secure connection. The process of deploying a site however remained the same.
There are issues with deploying a site in this way. You are essentially transferring files one by one to the server without any real management of that transfer. If the transfer fails for some reason, you may end up with a site that is only half updated. It can then be really difficult to work out what hasn’t been replaced or added, especially where you are updating an existing site. If you are updating some third-party software your update may include files that should be removed, but that may not be obvious to you and you risk leaving outdated files littering your file system. Updating using (S)FTP is a fragile process that leaves you open to problems caused by both connectivity and human error. Is there a better way to do this?
You’ll be glad to know that there is. A modern professional deployment workflow should have you moving away from fragile manual file transfers to deployments linked to code committed into source control.
The benefits of good practice
You may never have experienced any major issues while uploading files over FTP, and good FTP clients can help. However, there are other benefits to moving to modern deployment practices.
No surprises when you launch
If you are deploying in the way I suggest in this article you should have no surprises when you launch because the code you committed from your local environment should be the same code you deploy – and to staging if you have a staging server. A missing vital file won’t cause things to start throwing errors on updating the live site.
Being able to work collaboratively
Source control and good deployment practice makes working with your clients and other developers easy. Deploying first to a staging server means you can show your client updates and then push them live. If you subcontract some part of the work, you can give your subcontractor the ability to deploy to staging, leaving you with the final push to launch, once you know you are happy with the work.
Having a proper backup of site files with access to them from anywhere
The process I will outline requires the use of hosted, external source control. This gives you a backup of your latest commit and the ability to clone those files and start working on them from any machine, wherever you are.
Being able to jump back into a site quickly when the client wants a few changes
When doing client work it is common for some work to be handed over, then several months might go by without you needing to update the site. If you don’t have a good process in place, just getting back to work on it may take several hours for what could be only a few hours of work in itself. A solid method for getting your local copy up to date and deploying your changes live can cut that set-up time down to a few minutes.
The tool chain
In the rest of this article I assume that your current practice is to deploy your files over (S)FTP, using an FTP client. You would like to move to a more robust method of deployment, but without blowing apart your workflow and spending all Christmas trying to put it back together again. Therefore I’m selecting the most straightforward tools to get you from A to B.
Source control
Perhaps you already use some kind of source control for your sites. Today that is likely to be Git but you might also use Subversion or Mercurial. If you are not using any source control at all then I would suggest you choose Git, and that is what I will be working with in this article.
When you work with Git, you always have a local repository. This is where your changes are committed. You also have the option to push those changes to a remote repository; for example, GitHub. You may well have come across GitHub as somewhere you can go to download open source code. However, you can also set up private repositories for sites whose code you don’t want to make publicly accessible.
A hosted Git repository gives you somewhere to push your commits to and deploy from, so it’s a crucial part of our tool chain.
A deployment service
Once you have your files pushed to a remote repository, you then need a way to deploy them to your staging environment and live server. This is the job of a deployment service.
This service will connect securely to your hosting, and either automatically (or on the click of a button) transfer files from your Git commit to the hosting server. If files need removing, the service should also do this too, so you can be absolutely sure that your various environments are the same.
Tools to choose from
What follows are not exhaustive lists, but any of these should allow you to deploy your sites without FTP.
Hosted Git repositories
GitHub
Beanstalk
Bitbucket
Standalone deployment tools
Deploy
dploy.io
FTPloy
I’ve listed Beanstalk as a hosted Git repository, though it also includes a bundled deployment tool. Dploy.io is a standalone version of that tool just for deployment. In this tutorial I have chosen two separate services to show how everything fits together, and because you may already be using source control. If you are setting up all of this for the first time then using Beanstalk saves having two accounts – and I can personally recommend them.
Putting it all together
The steps we are going to work through are:
Getting your local site into a local Git repository
Pushing the files to a hosted repository
Connecting a deployment tool to your web hosting
Setting up a deployment
Get your local site into a local Git repository
Download and install Git for your operating system.
Open up a Terminal window and tell Git your name using the following command (use the name you will set up on your hosted repository).
> git config --global user.name "YOUR NAME"
Use the next command to give Git your email address. This should be the address that you will use to sign up for your remote repository.
> git config --global user.email "YOUR EMAIL ADDRESS"
Staying in the command line, change to the directory where you keep your site files. If your files are in /Users/rachel/Sites/mynicewebite you would type:
> cd /Users/rachel/Sites/mynicewebsite
The next command tells Git that we want to create a new Git repository here.
> git init
We then add our files:
> git add .
Then commit the files:
> git commit -m “Adding initial files”
The bit in quotes after -m is a message describing what you are doing with this commit. It’s important to add something useful here to remind yourself later why you made the changes included in the commit.
Your local files are now in a Git repository! However, everything should be just the same as before in terms of working on the files or viewing them in a local web server. The only difference is that you can add and commit changes to this local repository.
Want to know more about Git? There are some excellent resources in a range of formats here.
Setting up a hosted Git repository
I’m going to use Atlassian Bitbucket for my first example as they offer a free hosted and private repository.
Create an account on Bitbucket. Then create a new empty repository and give it a name that will identify the repository easily.
Click Getting Started and under Command Line select “I have an existing project”. This will give you a set of instructions to run on the command line. The first instruction is just to change into your working directory as we did before. We then add a remote repository, and run two commands to push everything up to Bitbucket.
cd /path/to/my/repo
git remote add origin https://myuser@bitbucket.org/myname/24ways-tutorial.git
git push -u origin --all
git push -u origin --tags
When you run the push command you will be asked for the password that you set for Bitbucket. Having entered that, you should be able to view the files of your site on Bitbucket by selecting the navigation option Source in the sidebar.
You will also be able to see commits. When we initially committed our files locally we added the message “Adding initial files”. If you select Commits from the sidebar you’ll see we have one commit, with the message we set locally. You can imagine how useful this becomes when you can look back and see why you made certain changes to a project that perhaps you haven’t worked on for six months.
Before working on your site locally you should run:
> git pull
in your working directory to make sure you have all of the most up-to-date files. This is especially important if someone else might work on them, or you just use multiple machines.
You then make your changes and add any changed or modified files, for example:
> git add index.php
Commit the change locally:
> git commit -m “updated the homepage”
Then push it to Bitbucket:
> git push origin master
If you want to work on your files on a different computer you clone them using the following command:
> git clone https://myuser@bitbucket.org/myname/24ways-tutorial.git
You then have a copy of your files that is already a Git repository with the Bitbucket repository set up as a remote, so you are all ready to start work.
Connecting a deployment tool to your repository and web hosting
The next step is deploying files. I have chosen to use a deployment tool called Deploy as it has support for Bitbucket. It does have a monthly charge – but offers a free account for open source projects.
Sign up for your account then log in and create your first project. Select Create an empty project. Under Configure Repository Details choose Bitbucket and enter your username and password.
If Deploy can connect, it will show you your list of projects. Select the one you want.
The next screen is Add New Server and here you need to configure the server that you want to deploy to. You might set up more than one server per project. In an ideal world you would deploy to a staging server for your client preview changes and then deploy once everything is signed off. For now I’ll assume you just want to set up your live site.
Give the server a name; I usually use Production for the live web server. Then choose the protocol to connect with. Unless your host really does not support SFTP (which is pretty rare) I would choose that instead of FTP.
You now add the same details your host gave you to log in with your SFTP client, including the username and password. The Path on server should be where your files are on the server. When you log in with an SFTP client and you get put in the directory above public_html then you should just be able to add public_html here.
Once your server is configured you can deploy. Click Deploy now and choose the server you just set up. Then choose the last commit (which will probably be selected for you) and click Preview deployment. You will then get a preview of which files will change if you run the deployment: the files that will be added and any that will be removed. At the very top of that screen you should see the commit message you entered right back when you initially committed your files locally.
If all looks good, run the deployment.
You have taken the first steps to a more consistent and robust way of deploying your websites. It might seem like quite a few steps at first, but you will very soon come to realise how much easier deploying a live site is through this process.
Your new procedure step by step
Edit your files locally as before, testing them through a web server on your own computer.
Commit your changes to your local Git repository.
Push changes to the remote repository.
Log into the deployment service.
Hit the Deploy now button.
Preview the changes.
Run the deployment and then check your live site.
Taking it further
I have tried to keep things simple in this article because so often, once you start to improve processes, it is easy to get bogged down in all the possible complexities. If you move from deploying with an FTP client to working in the way I have outlined above, you’ve taken a great step forward in creating more robust processes. You can continue to improve your procedures from this point.
Staging servers for client preview
When we added our server we could have added an additional server to use as a staging server for clients to preview their site on. This is a great use of a cheap VPS server, for example. You can set each client up with a subdomain – clientname.yourcompany.com – and this becomes the place where they can view changes before you deploy them.
In that case you might deploy to the staging server, let the client check it out and then go back and deploy the same commit to the live server.
Using Git branches
As you become more familiar with using Git, and especially if you start working with other people, you might need to start developing using branches. You can then have a staging branch that deploys to staging and a production branch that is always a snapshot of what has been pushed to production. This guide from Beanstalk explains how this works.
Automatic deployment to staging
I wouldn’t suggest doing automatic deployment to the live site. It’s worth having someone on hand hitting the button and checking that everything worked nicely. If you have configured a staging server, however, you can set it up to deploy the changes each time a commit is pushed to it.
If you use Bitbucket and Deploy you would create a deployment hook on Bitbucket to post to a URL on Deploy when a push happens to deploy the code. This can save you a few steps when you are just testing out changes. Even if you have made lots of changes to the staging deployment, the commit that you push live will include them all, so you can do that manually once you are happy with how things look in staging.

Get set up for the new year
I love to start the New Year with a clean slate and improved processes. If you are still wrangling files with FTP then this is one thing you could tick off your list to save you time and energy in 2015. Post to the comments if you have suggestions of tools or ideas for ways to enhance this type of set-up for those who have already taken the first steps. |

A Holiday Wish |
A friend and I were talking the other day about why clients spend more on toilet cleaning than design, and how the industry has changed since the mid-1990s, when we got our starts. Early in his career, my friend wrote a fine CSS book, but for years he has called himself a UX designer. And our conversation got me thinking about how I reacted to that title back when I first started hearing it.
“Just what this business needs,” I said to myself, “another phony expert.”
Okay, so I was wrong about UX, but my touchiness was not altogether unfounded. In the beginning, our industry was divided between freelance jack-of-all-trade punks, who designed and built and coded and hosted and Photoshopped and even wrote the copy when the client couldn’t come up with any, and snot-slick dot-com mega-agencies that blew up like Alice and handed out titles like impoverished nobles in the years between the world wars.
I was the former kind of designer, a guy who, having failed or just coasted along at a cluster of other careers, had suddenly, out of nowhere, blossomed into a web designer—an immensely curious designer slash coder slash writer with a near-insatiable lust to shave just one more byte from every image. We had modems back then, and I dreamed in sixteen colors. My source code was as pretty as my layouts (arguably prettier) and I hoovered up facts and opinions from newsgroups and bulletin boards as fast as any loudmouth geek could throw them. It was a beautiful life.
But soon, too soon, the professional digital agencies arose, buying loft buildings downtown, jacking in at T1 speeds, charging a hundred times what I did, and communicating with their clients in person, in large artfully bedecked rooms, wearing hand-tailored Barney’s suits and bringing back the big city bullshit I thought I’d left behind when I quit advertising to become a web designer.
Just like the big bad ad agencies of my early career, the new digital agencies stocked every meeting with a totem pole worth of ranks and titles. If the client brought five upper middle managers to the meeting, the agency did likewise. If fifteen stakeholders got to ask for a bigger logo, fifteen agency personnel showed up to take notes on the percentage of enlargement required.
But my biggest gripe was with the titles.
The bigger and more expensive the agency, the lousier it ran with newly invented titles. Nobody was a designer any more. Oh, no. Designer, apparently, wasn’t good enough. Designer was not what you called someone you threw that much money at.
Instead of designers, there were user interaction leads and consulting middleware integrators and bilabial experience park rangers and you name it. At an AIGA Miami event where I was asked to speak in the 1990s, I once watched the executive creative director of the biggest dot-com agency of the day make a presentation where he spent half his time bragging that the agency had recently shaved down the number of titles for people who basically did design stuff from forty-six to just twenty-three—he presented this as though it were an Einsteinian coup—and the other half of his time showing a film about the agency’s newly opened branch in Oslo. The Oslo footage was shot in December. I kept wondering which designer in the audience who lived in the constant breezy balminess of Miami they hoped to entice to move to dark, wintry Norway. But I digress.
Shortly after I viewed this presentation, the dot-com world imploded, brought about largely by the euphoric excess of the agencies and their clients. But people still needed websites, and my practice flourished—to the point where, in 1999, I made the terrifying transition from guy in his underwear working freelance out of his apartment to head of a fledgling design studio. (Note: you never stop working on that change.)
I had heard about experience design in the 1990s, but assumed it was a gig for people who only knew one font.
But sometime around 2004 or 2005, among my freelance and small-studio colleagues, like a hobbit in the Shire, I began hearing whispers in the trees of a new evil stirring. The fires of Mordor were burning. Web designers were turning in their HTML editing tools and calling themselves UXers.
I wasn’t sure if they pronounced it “uck-sir,” or “you-ex-er,” but I trusted their claims to authenticity about as far as I trusted the actors in a Doctor Pepper commercial when they claimed to be Peppers. I’m an UXer, you’re an UXer, wouldn’t you like to be an UXer too? No thanks, said I. I still make things. With my hands.
Such was my thinking. I may have earned an MFA at the end of some long-past period of soul confusion, but I have working-class roots and am profoundly suspicious of, well, everything, but especially of anything that smacks of pretense. I got exporting GIFs. I didn’t get how white papers and bullet points helped anybody do anything.
I was wrong. And gradually I came to know I was wrong. And before other members of my tribe embraced UX, and research, and content strategy, and the other airier consultant services, I was on board. It helped that my wife of the time was a librarian from Michigan, so I’d already bought into the cult of information architecture. And if I wasn’t exactly the seer who first understood how borderline academic practices related to UX could become as important to our medium and industry as our craft skills, at least I was down a lot faster than Judd Apatow got with feminism. But I digress.
I love the web and all the people in it. Today I understand design as a strategic practice above all. The promise of the web, to make all knowledge accessible to all people, won’t be won by HTML5, WCAG 2, and responsive web design alone.
We are all designers. You may call yourself a front-end developer, but if you spend hours shaving half-seconds off an interaction, that’s user experience and you, my friend, are a designer. If the client asks, “Can you migrate all my old content to the new CMS?” and you answer, “Of course we can, but should we?”, you are a designer. Even our users are designers. Think about it.
Once again, as in the dim dumb dot-com past, we seem to be divided by our titles. But, O, my friends, our varied titles are only differing facets of the same bright gem. Sisters, brothers, we are all designers. Love on! Love on!
And may all your web pages, cards, clusters, clumps, asides, articles, and relational databases be bright. |

Why Bother with Accessibility? |
Web accessibility (known in other fields as inclusive design or universal design) is the degree to which a website is available to as many people as possible. Accessibility is most often used to describe how people with disabilities can access the web.
How we approach accessibility
In the web community, there’s a surprisingly inconsistent approach to accessibility. There are some who are endlessly dedicated to accessible web design, and there are some who believe it so intrinsic to the web that it shouldn’t be considered a separate topic. Still, of those who are familiar with accessibility, there’s an overwhelming number of designers, developers, clients and bosses who just aren’t that bothered.
Over the last few months I’ve spoken to a lot of people about accessibility, and I’ve heard the same reasons to ignore it over and over again. Let’s take a look at the most common excuses.
Excuse 1: “People with disabilities don’t really use the web”
Accessibility will make your site available to more people — the inclusion case
In the same way that the accessibility of a building isn’t just about access for wheelchair users, web accessibility isn’t just about blind users and screen readers. We can affect positively the lives of many people by making their access to the web easier.
There are four main types of disability that affect use of the web:
Visual
Blindness, low vision and colour-blindness
Auditory
Profoundly deaf and hard of hearing
Motor
The inability to use a mouse, slow response time, limited fine motor control
Cognitive
Learning difficulties, distractibility, the inability to focus on large amounts of information
None of these disabilities are completely black and white
Examining deafness, it’s clear from the medical scale that there are many grey areas between full hearing and total deafness:
mild
moderate
moderately severe
severe
profound
totally deaf
For eyesight, and brain conditions that affect what users see, there is a huge range of conditions and challenges:
astigmatism
colour blindness
akinetopsia (motion blindness)
scotopic visual sensitivity (visual stress related to light)
visual agnosia (impaired recognition or identification of objects)
While we might have medical and government-recognised definitions that tell us what makes a disability, day-to-day life is not so straightforward. People experience varying degrees of different conditions, and often one or more conditions at a time, creating a false divide when you view disability in terms of us and them.
Impairments aren’t always permanent
As we age, we’re more likely to experience different levels of visual, auditory, motor and cognitive impairments. We might have an accident or illness that affects us temporarily. We might struggle more earlier or later in the day. There are so many little physiological factors that affect the way people interact with the web that we can’t afford to make any assumptions based on our own limited experiences.
Impairments might be somewhere between the user and the website
There are also impairments that aren’t directly related to the user. Environmental factors have a huge effect on the way people interact with the web. These could be:
Low bandwidth, or intermittent internet connection
Bright light, rain, or other weather-based conditions
Noisy environments, or a location where the user doesn’t want to disturb their neighbours with sound
Browsing with mobile devices, games consoles and other non-desktop devices
Browsing with legacy browsers or operating systems
Such environmental factors show that it’s not just those with physical impairments who benefit from more accessible websites. We started designing responsive websites so we could be more future-friendly, and with a shared goal of better optimised experiences, accessibility should be at the core of responsive web design.
Excuse 2: “We don’t want to affect the experience for the majority of our users”
Accessibility will improve your site for all your users — the usability case
On a basic level, the different disability groups, as shown in the inclusion case, equate to simple usability goals:
Visual – make it easy to read
Auditory – make it easy to hear
Motor – make it easy to interact
Cognitive – make it easy to understand and focus
Taking care to ensure good usability in these areas will also have an impact on accessibility. Unless your site is catering specifically to a particular disability, where extreme optimisation is most beneficial, taking care to design with accessibility in mind will rarely negatively affect the experience of your wider audience.
Excuse 3: “We don’t have the budget for accessibility”
Accessibility will make you money — the business case
By reducing your audience through ignoring accessibility, you’re potentially excluding the income from those users. Designing with accessibility in mind from the beginning of a project makes it easier to make small inexpensive optimisations as part of the design and development process, rather than bolting on costly updates to increase your potential audience later on.
The following are excerpts from a white paper about companies that increased the accessibility of their websites to comply with government regulation.
Improvements in accessibility doubled Legal and General’s life insurance sales online.
Improvements in accessibility increased Tesco’s grocery home delivery sales by £13 million in 2005… To their surprise they found that many normal visitors preferred the ease of navigation and improved simplicity of the [parallel] accessible site and switched to use it. Tesco have replaced their ‘normal’ site with their accessible version and expect a further increase in revenues.
Improvements in accessibility increased Virgin.net sales by 68%.

Excuse 4: “Accessible websites are ugly”
Accessibility won’t stop your site from being beautiful — the beauty case
Many people use ugly accessible websites as proof that all accessible websites are ugly. This just isn’t the case. I’ve compiled some examples of beautiful and accessible websites with screenshots of how they look through the Color Oracle simulator and how they perform when run through Webaim’s Wave accessibility checker tool.
While automated tools are no substitute for real users, they can help you learn more about good practices, and give you guidance on where your site needs improvements to make it more accessible.
Amazon.co.uk
It may not be a decorated beauty, but Amazon is often first in functional design. It’s a huge website with a lot of interactive content, but it generates just five errors on the Wave test, and is easy to read under a Color Oracle filter.

24 ways
When Tim Van Damme redesigned 24 ways back in 2007, it was a striking and unusual design that showed what could be achieved with CSS and some imagination. Despite the complexity of the design, it gets an outstanding zero errors on the Wave test, and is still readable under a Color Oracle filter.

Opera’s Shiny Demos
Demos and prototypes are notorious for ignoring accessibility, but Opera’s Shiny Demos site shows how exploring new technologies doesn’t have to exclude anyone. It only gets one error on the Wave test, and looks fine under a Color Oracle filter.

SoundCloud
When a site is more app-like, relying on more interaction from the user, accessibility can be more challenging. However, SoundCloud only gets one error on the Wave test, and the colour contrast holds up well under a Color Oracle filter.

Education and balance
As with most web design, doing accessibility well is about combining your knowledge of accessibility with your project’s context to create a balance that serves your users’ needs. Your types of content and interactions will dictate one set of constraints. Your users’ needs and goals will dictate another. In broad terms, web design as a practice is finding the equilibrium between these constraints.
And then there’s just caring. The web as a platform is open, affordable and available to many. Accessibility is our way to ensure that nobody gets shut out. |

Hello, 24 ways. I’m Ashley and I sell property insurance. I’m interrupting your Christmas countdown with an article about rental property software and a guy, Pete, who selflessly encouraged me to build my first web app. It doesn’t sound at all festive, or — considering I’ve used both “insurance” and “rental property” — interesting, but do stick with me. There’s eggnog at the end.
I run a property insurance business, Brokers Direct. It’s a small operation, but well established. We’ve been selling landlord insurance on the web for over thirteen years, for twelve of which we have provided our clients with third-party software for managing their rental property portfolios. Free. Of. Charge.
It sounds like a sweet deal for our customers, but it isn’t. At least, not any more. The third-party software is victim to years of neglect by its vendor. Its questionable interface, garish visuals and, ahem, clip art icons have suffered from a lack of updates. While it was never a contender for software of the year, I’ve steadily grown too embarrassed to associate my business with it.
The third-party rental property software we distributed
I wanted to offer my customers a simple, clean and lightweight alternative. In an industry that’s dominated by dated and bloated software, it seemed only logical that I should build my own rental property tool.
The long learning-to-code slog
Learning a programming language is daunting, the source of my frustration stemming from a non-programming background. Generally, tutorials assume a degree of familiarity with programming, whether it be tools, conventions or basic skills. I had none and, at the time, there was nothing on the web really geared towards a novice. I reached the point where I genuinely thought I was just not cut out for coding. Surrendering to my feelings of self-doubt and frustration, I sourced a local Rails developer, Pete, to build it for me.
Pete brought a pack of index cards to our meeting. Index cards that would represent each feature the rental property software would launch with.
“OK,” he began. “We’ll need a user model, tenant model, authentication, tenant and property relationships…” A dozen index cards with a dozen features lined the coffee table in a grid-like format. Logical, comprehensible, achievable. Seeing the app laid out in a digestible manner made it seem surmountable. Maybe I could do this.
“I’ve been trying to learn Rails…”, I piped up.
I don’t know why I said it. I was fully prepared to hire Pete to do the hard work for me. But Pete, unprompted, gathered the index cards and neatly stacked them together, coasting them across the table towards me. “You should build this”.
Pete, a full-time freelance developer at the time, was turning down a paying job in favour of encouraging me to learn to code. Looking back, I didn’t realise how significant this moment was.
That evening, I took Pete’s index cards home to make a start on my app, slowly evolving each of the cards into a working feature. Building the app solo, I turned to Stack Overflow to solve the inevitable coding hurdles I encountered, as well as calling on a supportive Rails community. Whether they provided direct solutions to my programming woes, or simply planted a seed on how to solve a problem, I kept coding. Many months later, and after several more doubtful moments, Lodger was born.
Property overview of my app, Lodger.
If I can do it, so can you
I misspent a lot of time building Twitter and blogging applications (apparently, all Rails tutorials centre around Twitter and blogging). If I could rewind and impart some advice to myself, this is what I’d say.
There’s no magic formula
“I haven’t quite grasped Rails routing. I should tackle another tutorial.”
Making excuses — or procrastination — is something we are all guilty of. I was waiting for a programming book that would magically deposit a grasp of the entire Ruby syntax in my head. I kept buying books thinking each one would be the one where it all clicked. I now have a bookshelf full of Ruby material, all of which I’ve barely read, and none of which got me any closer to launching my web app. Put simply, there’s no magic formula.
Break it down
Whatever it is you want to build, break it down into digestible chunks. Taking Pete’s method as an example, having an index card represent an individual feature helped me tremendously. Tackle one at a time. Even if each feature takes you a month to build, and you have eight features to launch with, after eight months you’ll have your MVP. Remember, if you do nothing each day, it adds up to nothing.
Have a tangible product to build
I have a wonderful habit of writing down personal notes, usually to express my feelings at the time or to log an idea, only to uncover them months or years down the line, long after I forgot I had written them. I made a timely discovery while writing this article, discovering this gem while flicking through a battered Moleskine:
“I don’t seem to be making good progress with learning Rails, but development still excites me. I should maybe stop doing tutorials and work towards building a specific app.”
Having a real product to work on, like I did with Lodger, means you have something tangible to apply the techniques you are learning. I found this prevented me from flitting aimlessly between tutorials and books, which is an easy area to accidentally remain in.
Team up
If possible, team up with a designer and create something together. Designers are great at presenting features in a way you’d never have considered. You will learn a lot from making their designs come to life.
Your homework for the holiday
Despite having a web app under my belt, I am not a programmer. I tinker with code, piecing enough bits of it together to make something functional. And that’s OK! I’m not excusing sloppiness, but if we aimed for perfection every time, we’d never execute any of our ideas.
As the holidays approach and you’ve exhausted yet another viewing of The Muppet Christmas Carol (or is that just my guilty pleasure at Christmas?), you may have time on your hands. Time to explore an idea you’ve been sitting on, but — plagued with procrastination and doubt — have yet to bring to life. This holiday, I am here to say to you what Pete said to me.
You should build this.
You don’t need to be the next Mark Zuckerberg or Larry Page. You just have to learn enough to get it done.
PS: I lied about the eggnogg, but try capturing somebody’s attention when you tell them you sell property insurance! |

Project Hubs: A Home Base for Design Projects |
SCENE: A design review meeting. Laptop screens. Coffee cups.
Project manager: Hey, did you get my email with the assets we’ll be discussing?
Client: I got an email from you, but it looks like there’s no attachment.
PM: Whoops! OK. I’m resending the files with the attachments. Check again?
Client: OK, I see them. It’s homepage_v3_brian-edits_FINAL_for-review.pdf, right?
PM: Yeah, that’s the one.
Client: OK, hang on, Bill’s going to print them out. (3-minute pause. Small talk ensues.)
Client: Alright, Bill’s back. We’re good to start.
Brian: Oh, actually those homepage edits we talked about last time are in the homepage_v4_brian_FINAL_v2.pdf document that I posted to Basecamp earlier today.
Client: Oh, OK. What message thread was that in?
Brian: Uh, I’m pretty sure it’s in “Homepage Edits and Holiday Schedule.”
Client: Alright, I see them. Bill’s going back to the printer. Hang on a sec…
This is only a slightly exaggerated version of my experience in design review meetings.
The design project dance is a sloppy one. It involves a slew of email attachments, PDFs, PSDs, revisions, GitHub repos, staging environments, and more. And while tools like Basecamp can help manage all these moving parts, it can still be incredibly challenging to extract only the important bits, juggle deliverables, and see how your project is progressing.
Enter project hubs.
Project hubs
A project hub consolidates all the key design and development materials onto a single webpage presented in reverse chronological order. The timeline lives online (either publicly available or password protected), so that everyone involved in the team has easy access to it.
A project hub.
I was introduced to project hubs after seeing Dan Mall’s open redesign of Reading Is Fundamental. Thankfully, I had a chance to work with Dan on two projects where I got to see firsthand how beneficial a project hub can be. Here’s what makes a project hub great:
Serves as a centralized home base for the project
Trains clients and teams to decide in the browser
Easily and visually view project’s progress
Provides an archive for project artifacts
A home base
Your clients and colleagues can expect to get the latest and greatest updates to your project when visiting the project hub, the same way you’d expect to get the latest information on a requested topic when you visit a Wikipedia page. That’s the beauty of URIs that don’t change.
Creating a project hub reduces a ton of email volley nonsense, and eliminates the need to produce files and directories with staggeringly ridiculous names like design/12.13.13/team/brian/for_review/_FINAL/styletile_121313_brian-edits-final_v2_FINAL.pdf. The team can simply visit the project hub’s URL and click the link to whatever artifact they need. Need to make an update? Simply update the link on the project hub. No more email tango and silly file names.
Deciding in the browser
Let’s change the phrase “designing in the browser” to “deciding in the browser.”
Dan Mall
We make websites, but all too often we find ourselves looking at web design artifacts in abstractions. We email PDFs to each other, glance at mockup JPGs on our desktops, and of course kill trees in order to print out designs so that we can scribble in the margins. All of these practices subtly take everyone further and further away from the design’s eventual final resting place: the browser.
Because a project hub is just a simple webpage, reviewing designs is as easy as clicking some links, which keep your clients and teams in the browser.
You can keep people in the browser with yet another clever trick from the wily Dan Mall: instead of sending clients PDFs or JPGs, he created a simple webpage and tossed his static visuals into the template (you can view an example here). This forces clients to review web design work in the browser rather than launching a PDF viewer or Preview.
Now this all might sound trivial to you (“Of course my client knows that we’re designing a website!”), but keeping the design artifacts in the browser subconsciously helps remind everyone of the medium for which you’re designing, which helps everyone focus on the right aspects of the design and have the right conversations.
Progress over time
When you’re in the trenches, it’s often hard to visualize how a project is progressing. Tools like Basecamp include discussions, files, to-dos, and more, which are all great tools but also make things a bit noisy. Project hubs provide you and your clients a quick and easy way to see at a glance how things are coming along. Teams can rest assured they’re viewing the most current versions of designs, and managers can share progress with stakeholders simply by providing a link to the project hub.
Over time, a project hub becomes an easily accessible archive of all the design decisions, which makes it easy to compare and contrast different versions of designs and prototypes.
Setting up a project hub
Setting up your own project hub is pretty simple. Simply create a webpage with some basic styles and branding. I’ve created a project hub template that’s available on GitHub if you want a jump-start.
Publish the webpage to a URL somewhere that makes sense (we’ve found that a subdomain of your site works quite well) and share it with everyone involved in the project. Bookmark it. Let everyone know that this is where design updates will be shared, and that they can always come back to the project hub to track the project’s progress.
When it comes time to share new updates, simply add a new node to the timeline and republish the webpage. Simple FTPing works just fine, but it might make sense to keep track of changes using version control. Our project hub for our open redesign of the Pittsburgh Food Bank is managed on GitHub, which means that I can make edits to the hub right from GitHub. Thanks to the magical wizardry of webhooks, I can automatically deploy the project hub so that everything stays in sync. That’s the fancy-pants way to do it, and is certainly not a requirement. As long as you’re able to easily make edits and keep your project hub up to date, you’re good to go.
So that’s the hubbub
Project hubs can help tame the chaos of the design process by providing a home base for all key design and development materials. Keep the design artifacts in the browser and give clients and colleagues quick insight into your project’s progress.
Happy hubbing! |

Credits and Recognition |
A few weeks ago, I saw a friendly little tweet from a business congratulating a web agency on being nominated for an award. The business was quite happy for them and proud to boot — they commented on how the same agency designed their website, too.
What seemed like a nice little shout-out actually made me feel a little disappointed. Why? In reality, I knew that the web agency didn’t actually design the site — I did, when I worked at a different agency responsible for the overall branding and identity.
I certainly wasn’t disappointed at the business — after all, saying that someone designed your site when they were responsible for development is an easy mistake to make. Chances are, the person behind the tweets and status updates might not even know the difference between words like design and development.
What really disappointed me was the reminder of how many web workers out there never explain their roles in a project when displaying work in a portfolio. If you’re strictly a developer and market yourself as such, there might be less room for confusion, but things can feel a little deceptive if you offer a wide range of services yet never credit the other players when collaboration is part of the game. Unfortunately, this was the case in this situation. Whatever happened to credit where credit’s due?
Advertising attribution
Have you ever thumbed through an advertising annual or browsed through the winners of an advertising awards website, like the campaign below from Kopenhagen Chocolate on Advertising Age? If so, it’s likely that you’ve noticed some big differences in how the work is credited.
Everyone involved in a creative advertising project is mentioned.
Art directors, writers, creative directors, photographers, illustrators and, of course, the agency all get a fair shot at fifteen minutes of fame. Why can’t we take this same idea and introduce it to our own showcases?
Crediting on client sites
Ah, the good old days of web rings, guestbooks, and under construction GIFs, when slipping in a cheeky “designed by” link in the footer of your masterpiece was just another common practice. These days most clients, especially larger companies and corporations, aren’t willing to have any names on their site except their own.
If you’d still like to leave a little proof of authorship on a website, consider adding a humans.txt file to the root of the site and, if possible, add an author tag in the <head> of the site:
<link type="text/plain" rel="author" href="http://domain/humans.txt">
It’s a great way to add more detailed information than just a meta name without being intrusive. The example on the humanstxt.org website serves to act as a guideline, but how much detail you add is completely up to you and your team.
Part of the humans.txt file on humanstxt.org
Alternatively, you can use the HTML5 rel="author" attribute to link to information about the author of the page in the form of a mailto: address, a link to a contact form, or a separate authors page.
Crediting in portfolios
While humans.txt is a great approach when you’re authoring a site, it’s even more important to clearly define your role in your own portfolio.
While I believe it’s proper etiquette to include the names of folks you collaborated with, sometimes it might not be necessary (or even possible) to list every single person, especially if you’ve worked with a large agency.
“Fake it till you make it” is not a term that should apply to your portfolio. Clearly stating your own responsibilities means that nobody else browsing your work samples will assume that you did more than your actual share, and being ambiguous about your role isn’t fair to yourself, or others.
Before adding any work to your portfolio, ensure that you have permission from your client. Even if you included a clause in your contract about being allowed to post your work online, it’s always best to double-check. Sometimes you might not know if your work has been officially launched, and leaking something before it’s ready is bound to make a client frown.
Examples
There are plenty of portfolios out there that we can use for inspiration. Here are some examples that I like from other folks in the web industry:
Anna Debenham
In her portfolio, Anna outlines her responsibilities and those of others.
In the description, Anna clearly explains her duties of doing the HTML and CSS, along with performing research and testing the prototype in schools. She also credits Laura Kalbag for the design work.
Naomi Atkinson Design
The work portfolio of Naomi Atkinson Design is short and to the point — they were responsible for the iPhone app design and IA for Artspotter.
The portfolio of Naomi Atkinson Design states clearly what they did.
Amber Weinberg
Amber Weinberg is strictly a developer, but a potential client could see her portfolio and assume she might be a designer as well. To avoid any misunderstandings, she states her roles up front in a section called “What I Did,” supported by examples of her code.
Amber Weinberg sets out all her roles in each of her portfolio’s case studies.
What if someone doesn’t want to be credited?
Let’s face it — we’ve all been there. A project, for whatever reason, turns out to be an absolute disaster and we don’t feel like it’s an accurate representation of the quality of our work.
If you’re crediting someone else but suspect they might rather pretend it never happened, be sure to drop them a line and ask if they’d like to be included. And, if someone contacts you and asks to remove their name, don’t feel offended — just politely remove it.
Get updating!
Now that the holiday season is almost here, many of you might be planning to set aside some time for personal projects. Grab yourself a gingerbread latte and get those portfolios up to date. Remember, It doesn’t have to be long-winded, just honest. Happy holidays! |

Managing a Mind |
On 21 May 2013, I woke in a hospital bed feeling exhausted, disorientated and ashamed. The day before, I had tried to kill myself.
It’s very hard to write about this and share it. It feels like I’m opening up the deepest recesses of my soul and laying everything bare, but I think it’s important we share this as a community. Since starting tentatively to write about my experience, I’ve had many conversations about this: sharing with others; others sharing with me. I’ve been surprised to discover how many people are suffering similarly, thinking that they’re alone. They’re not.
Due to an insane schedule of teaching, writing, speaking, designing and just generally trying to keep up, I reached a point where my buffers completely overflowed. I was working so hard on so many things that I was struggling to maintain control. I was living life on fast-forward and my grasp on everything was slowly slipping.
On that day, I reached a low point – the lowest point of my life – and in that moment I could see only one way out. I surrendered. I can’t really describe that moment. I’m still grappling with it. All I know is that I couldn’t take it any more and I gave up.
I very nearly died.
I’m very fortunate to have survived. I was admitted to hospital, taken there unconscious in an ambulance. On waking, I felt overwhelmed with shame and overcome with remorse, but I was resolved to grasp the situation and address it. The experience has forced me to confront a great deal of issues in my life; it has also encouraged me to seek a deeper understanding of my situation and, in particular, the mechanics of the mind.
The relentless pace of change
We work in a fast-paced industry: few others, if any, confront the daily challenges we face. The landscape we work within is characterised by constant flux. It’s changing and evolving at a rate we have never experienced before. Few industries reinvent themselves yearly, monthly, weekly… Ours is one of these industries. Technology accelerates at an alarming rate and keeping abreast of this change is challenging, to say the least.
As designers it can be difficult to maintain a knowledge bank that is relevant and fit for purpose. We’re on a constant rollercoaster of endless learning, trying to maintain the pace as, daily, new ideas and innovations emerge — in some cases fundamentally changing our medium.
Under the pressure of client work or product design and development, it can be difficult to find the time to focus on learning the new skills we need to remain relevant and functionally competent. The result, all too often, is that the edges of our days have eroded. We no longer work nine to five; instead we work eight to six, and after the working day is over we regroup to spend our evenings learning. It’s an unsustainable situation.
From the workshop to the web
Added to this pressure to keep up, our work is now undertaken under a global gaze, conducted under an ever-present spotlight. Tools like Dribbble, Twitter and others, while incredibly powerful, have an unfortunate side effect, that of unfolding your ideas in public. This shift, from workshop to web, brings with it additional pressure.
In the past, the early stages of creativity took place within the relative safety of the workshop, an environment where one could take risks and gather feedback from a trusted few. We had space to make and space to break. No more. Our industry’s focus (and society’s focus) on sharing, leads us now to play out our decisions in public. This shift has changed us culturally, slowly but surely easing every aspect of our process – and lives – from private to public. This is at once liberating and debilitating.
If you’re not careful, an addiction to followers, likes, retweets, page views and other forms of measurement can overwhelm you. When you release your work into the wild and all it’s greeted with is silence, it can cripple you.
Reflecting on this, in an insightful article titled Derailed, Rogie King asks, “Can social popularity take us off the course of growth and where we were intended to go?” He makes a powerful point, that perhaps we might focus on what really matters, setting aside statistics. He concludes that to grow as practitioners we might be best served by seeking out critique through other avenues, away from the social spotlight.
On status anxiety and impostor syndrome
Following my experience I embarked on a period of self-reflection. I wanted to discover what had driven me to take the course of action I had. I wanted to ensure it never happened again. I wanted to understand how the mind works and, in so doing, learn a little more about myself.
I’ve only begun this journey, but two things I discovered resonated with me: the twin pressures of status anxiety and impostor syndrome.
In his excellent book Status Anxiety, the philosopher Alain de Botton explores a growing concern with status anxiety, a worry about how others perceive us and how this shapes our relationship with the world. He states:
We all worry about what others think of us. We all long to succeed and fear failure. We all suffer – to a greater or lesser degree, usually privately and with embarrassment – from status anxiety. […] This is an almost universal anxiety that rarely gets mentioned directly: an anxiety about what others think of us; about whether we’re judged a success or a failure, a winner or a loser.
We see these pressures played out and amplified in the social sphere we all inhabit. We are social animals and we cannot help but react to the landscape we live and work within. Even if your work receives the public praise you so secretly desire, you find yourself questioning this praise.
A psychological phenomenon in which sufferers are unable to internalise their accomplishments, impostor syndrome is far more widespread than you’d imagine. The author Leigh Buchanan describes it as “A fear that one is not as smart or capable as others think.” As she puts it, “People who feel like frauds chalk up their accomplishments to external factors such as luck and timing, or worry they are coasting on charm and personality rather than on talent.”
At the bottom, this was all I could see. I felt overwhelmed by others’ perception of me. Was I a success or a failure? Would I be discovered as the fraud I’d convinced myself that I was? These twin pressures – that I was unconscious of at the time – had lead me to a place of crippling self-doubt, questioning my very existence.
The act of discovery, of investigating how the mind functions, led me to a deeper understanding of myself. Developing an awareness of psychology and learning about conditions like status anxiety and impostor syndrome helped me to understand and recognise how my mind worked, enabling me to manage it more effectively.
Make it count
Reflecting upon my experience, I began to regroup, to focus on what really mattered. I’d taken on too much — as I believe many of us do. I was guilty of wanting to do all the things. I started to introduce pauses. Before blindly saying yes to everything, I forced myself to pause and ask: “Is this important?”
Our community offers us huge benefits, but an always-on culture in which we’re bombarded daily by opportunity places temptation in our paths. It’s easy to get sucked in to a vortex of wanting to be a part of everything. It’s important, however, to focus. As Simon Collison puts it:
I cull and surrender topics. Then I focus on my strengths, mastering my core skills.
We only have so much time and we can only do so much. It’s impossible, indeed futile, to try to do everything. Sometimes we need to step back a little and just enjoy life, enjoy others’ achievements, without feeling the need to be actively involved ourselves.
As Mahatma Ghandi put it:
A ‘no’ uttered from deepest conviction is better and greater than a ‘yes’ merely uttered to please, or what is worse, to avoid trouble.
Young India, volume 9, 1927
We need to learn to say no a little more often. We need to focus on the work that matters. This, coupled with an understanding of the mind and how it works, can help us achieve a happier balance between work and life.
Don’t waste your time. You only have one life. Make it count. |

Run Ragged |
You care about typography, right? Do you care about words and how they look, read, and are understood? If you pick up a book or magazine, you notice the moment something is out of place: an orphan, rivers within paragraphs of justified prose, or caps masquerading as small caps. So why, I ask you, is your stance any different on the web?
We’re told time and time again that as a person who makes websites we have to get comfortable with our lack of control. On the web, this is a feature, not a bug. But that doesn’t mean we have to lower our standards, or not strive for the same amount of typographic craft of our print-based cousins. We shouldn’t leave good typesetting at the door because we can’t control the line length.
When I typeset books, I’d spend hours manipulating the text to create a pleasurable flow from line to line. A key aspect of this is manicuring the right rag — the vertical line of words on ranged-left text. Maximising the space available, but ensuring there are no line breaks or orphaned words that disrupt the flow of reading. Setting a right rag relies on a bunch of guidelines — or as I was first taught to call them, violations!
Violation 1. Never break a line immediately following a preposition
Prepositions are important, frequently used words in English. They link nouns, pronouns and other words together in a sentence. And links should not be broken if you can help it. Ending a line on a preposition breaks the join from one word to another and forces the reader to work harder joining two words over two lines.
For example:
The container is for the butter
The preposition here is for and shows the relationship between the butter and the container. If this were typeset on a line and the line break was after the word for, then the reader would have to carry that through to the next line. The sentence would not flow.
There are lots of prepositions in English – about 150 – but only 70 or so in use.
Violation 2. Never break a line immediately following a dash
A dash — either an em-dash or en-dash — can be used as a pause in the reading, or as used here, a point at which you introduce something that is not within the flow of the sentence. Like an aside. Ending with a pause on the end of the line would have the same effect as ending on a preposition. It disrupts the flow of reading.
Violation 3. No small words at the end of a line
Don’t end a line with small words. Most of these will actually be covered by violation №1. But there will be exceptions. My general rule of thumb here is not to leave words of two or three letters at the end of a line.
Violation 4. Hyphenation
In print, hyphens are used at the end of lines to join words broken over a line break. Mostly, this is used in justified body text, and no doubt you will be used to seeing it in newspapers or novels. A good rule of thumb is to not allow more than two consecutive lines to end with a hyphen.
On the web, of course, we can use the CSS hyphens property. It’s reasonably supported with the exception of Chrome. Of course, it works best when combined with justified text to retain the neat right margin.
Violation 5. Don’t break emphasised phrases of three or fewer words
If you have a few words emphasised, for example:
He calls this problem definition escalation
…then try not to break the line among them. It’s important the reader reads through all the words as a group.
How do we do all of that on the web?
All of those guidelines are relatively easy to implement in print. But what about the web? Where content is poured into a template from a CMS? Well, there are things we can do. Meet your new friend, the non-breaking space, or as you may know them: .
The guidelines above are all based on one decision for the typesetter: when should the line break?
We can simply run through a body of text and add the based on these sets of questions:
Are there any prepositions in the text? If so, add a after them.
Are there any dashes? If so, add a after them.
Are there any words of fewer than three characters that you haven’t already added spaces to? If so, add a after them.
Are there any emphasised groups of words either two or three words long? If so, add a in between them.
For a short piece of text, this isn’t a big problem. But for longer bodies of text, this is a bit arduous. Also, as I said, lots of websites use a CMS and just dump the text into a template. What then? We can’t expect our content creators to manually manicure a right rag based on these guidelines. In this instance, we really need things to be automatic.
There isn’t any reason why we can’t just pass the question of when to break the line straight to the browser by way of a script which compares the text against a set of rules. In plain English, this script could be to scan the text for:
Prepositions. If found, add after them.
Dashes. If found, add after them.
Words fewer than three characters long that aren’t prepositions. If found, add after them.
Emphasised phrases of up to three words in length. If found, add between all of the words.
And there we have it.
A note on fluidity
An important consideration of this script is that it doesn’t scan the text to see what is at the end of a line. It just looks for prepositions, dashes, words fewer than three characters long, and emphasised words within paragraphs and applies the accordingly regardless of where the thing lives. This is because in a fluid layout a word might appear in the beginning, middle or the end of a line depending on the width of the browser. And we want it to behave in the right way when it does find itself at the end.
See it in action!
My friend and colleague, Nathan Ford, has written a small JavaScript called Ragadjust that does all of this automatically. The script loops through a webpage, compares the text against the conditions, and then inserts in the places that violate the conditions above.
You can get the script from GitHub and see it in action on my own website.
Some caveats
As my friend Jon Tan says, “There are no rules in typography, just good or bad decisions”, and typesetting the right rag is no different.
The guidelines for the violations above are useful for justified text, too. But we need to be careful here. Too stringent adherence to these violations could lead to ugly gaps in our words — called rivers — as the browser forces justification.
The violation regarding short words at the end of sentences is useful for longer line lengths, or measures, of text. When the measure gets shorter, maybe five or six words, then we need to be more forgiving as to what wraps to the next line and what doesn’t. In fact, you can see this happening on my site where I’ve not included a check on the size of the browser window (purposefully, for this demo, of course. Ahem).
This article is about applying these guidelines to English. Some of them will, no doubt, cross over to other languages quite well. But for those languages, like German for instance, where longer words tend to be in more frequent use, then some of the rules may result in a poor right rag.
Marginal gains
In 2007, I spoke with Richard Rutter at SXSW on web typography. In that talk, Richard and I made a point that good typographic design — on the web, in print; anywhere, in fact — relies on small, measurable improvements across an entire body of work. From heading hierarchy to your grid system, every little bit helps. In and of themselves, these little things don’t really mean that much. You may well have read this article, shrugged your shoulders and thought, “Huh. So what?” But these little things, when added up, make a difference. A difference between good typographic design and great typographic design.

Get Started With GitHub Pages (Plus Bonus Jekyll) |
After several failed attempts at getting set up with GitHub Pages, I vowed that if I ever figured out how to do it, I’d write it up. Fortunately, I did eventually figure it out, so here is my write-up.
Why I think GitHub Pages is cool
Normally when you host stuff on GitHub, you’re just storing your files there. If you push site files, what you’re storing is the code, and when you view a file, you’re viewing the code rather than the output. What GitHub Pages lets you do is store those files, and if they’re HTML files, you can view them like any other website, so there’s no need to host them separately yourself.
GitHub Pages accepts static HTML but can’t execute languages like PHP, or use a database in the way you’re probably used to, so you’ll need to output static HTML files. This is where templating tools such as Jekyll come in, which I’ll talk about later.
The main benefit of GitHub Pages is ease of collaboration. Changes you make in the repository are automatically synced, so if your site’s hosted on GitHub, it’s as up-to-date as your GitHub repository. This really appeals to me because when I just want to quickly get something set up, I don’t want to mess around with hosting; and when people submit a pull request, I want that change to be visible as soon as I merge it without having to set up web hooks.
Before you get started
If you’ve used GitHub before, already have an account and know the basics like how to set up a repository and clone it to your computer, you’re good to go. If not, I recommend getting familiar with that first. The GitHub site has extensive documentation on getting started, and if you’re not a fan of using the command line, the official GitHub apps for Mac and Windows are great.
I also found this tutorial about GitHub Pages by Thinkful really useful, and it contains details on how to turn an existing repository into a GitHub Pages site.
Although this involves a bit of using the command line, it’s minimal, and I’ll guide you through the basics.
Setting up GitHub Pages
For this demo we’re going to build a Christmas recipe site — nothing complex, just a place to store recipes so we can share them with people, and they can fork or suggest changes to ones they like. My GitHub username is maban, and the project I’ve set up is called christmas-recipes, so once I’ve set up GitHub Pages, the site can be found here: http://maban.github.io/christmas-recipes/
You can set up a custom domain, but by default, the URL for your GitHub Pages site is your-username.github.io/your-project-name.
Set up the repository
The first thing we’re going to do is create a new GitHub repository, in exactly the same way as normal, and clone it to the computer. Let’s give it the name christmas-recipes. There’s nothing in it at the moment, but that’s OK.
After setting up the repository on the GitHub website, I cloned it to my computer in my Sites folder using the GitHub app (you can clone it somewhere else, if you want), and now I have a local repository synced with the remote one on GitHub.
Navigate to the repository
Now let’s open up the command line and navigate to the local repository. The easiest way to do this in Terminal is by typing cd and dragging and dropping the folder into the terminal window and pressing Return. You can refer to Chris Coyier’s GIF illustrating this very same thing, from last week’s 24 ways article “Grunt for People Who Think Things Like Grunt are Weird and Hard” (which is excellent).
So, for me, that’s…
cd /Users/Anna/Sites/christmas-recipes
Create a special GitHub Pages branch
So far we haven’t done anything different from setting up a regular repository, but here’s where things change.
Now we’re in the right place, let’s create a gh-pages branch. This tells GitHub that this is a special branch, and to treat the contents of it differently.
Make sure you’re still in the christmas-recipes directory, and type this command to create the gh-pages branch:
git checkout --orphan gh-pages
That --orphan option might be new to you. An orphaned branch is an empty branch that’s disconnected from the branch it was created off, and it starts with no commits, making it a special standalone branch. checkout switches us from the branch we were on to that branch.
If all’s gone well, we’ll get a message saying Switched to a new branch ‘gh-pages’.
You may get an error message saying you don’t have admin privileges, in which case you’ll need to type sudo at the start of that command.
Make gh-pages your default branch (optional)
The gh-pages branch is separate to the master branch, but by default, the master branch is what will show up if we go to our repository’s URL on GitHub. To change this, go to the repository settings and select gh-pages as the default branch.
If, like me, you only want the one branch, you can delete the master branch by following Oli Studholme’s tutorial. It’s actually really easy to do, and means you only have to worry about keeping one branch up to date.
If you prefer to work from master but push updates to the gh-pages branch, Lea Verou has written up a quick tutorial on how to do this, and it basically involves working from the master branch, and using git rebase to bring one branch up to date with another.
At the moment, we’ve only got that branch on the local machine, and it’s empty, so to be able to see something at our special GitHub Pages URL, we’ll need to create a page and push it to the remote repository.
Make a page
Open up your favourite text editor, create a file called index.html in your christmas-recipes folder, and put some exciting text in it. Don’t worry about the markup: all we need is text because right now we’re just checking it works.
Now, let’s commit and push our changes. You can do that in the command line if you’re comfortable with that, or you can do it via the GitHub app. Don’t forget to add a useful commit message.
Now we’re ready to see our gorgeous new site! Go to your-username.github.io/your-project-name and, hopefully, you’ll see your first GitHub Pages site. If not, don’t panic, it can take up to ten minutes to publish, so you could make a quick cake in a cup while you wait.
After a short wait, our page should be live! Hopefully that wasn’t too traumatic. Now we know it works, we can add some proper markup and CSS and even some more pages.
If you’re feeling brave, how about we take it to the next level…
Setting up Jekyll
Since GitHub Pages can’t execute languages like PHP, we need to give it static HTML files. This is fine if there are only a few pages, but soon we’ll start to miss things like PHP includes for content that’s the same on every page, like headers and footers.
Jekyll helps set up templates and turn them into static HTML. It separates markup from content, and makes it a lot easier for people to edit pages collaboratively. With our recipe site, we want to make it really easy for people to fix typos or add notes, without having to understand PHP. Also, there’s the added benefit that static HTML pages load really fast.
Jekyll isn’t officially supported on Windows, but it is still possible to run it if you’re prepared to get your hands dirty.
Install Jekyll
Back in Terminal, we’re going to install Jekyll…
gem install jekyll
…and wait for the script to run. This might take a few moments. It might take so long that you get worried its broken, but resist the urge to start mashing your keyboard like I did.
Get Jekyll to run on the repository
Fingers crossed nothing has gone wrong so far. If something did go wrong, don’t give up! Check this helpful post by Andy Taylor – you probably just need to install something else first.
Now we’re going to tell Jekyll to set up a new project in the repository, which is in my Sites folder (yours may be in a different place). Remember, we can drag the directory into the terminal window after the command.
jekyll new /Users/Anna/Sites/christmas-recipes
If everything went as expected, we should get this error message: Conflict: /Users/Anna/Sites/christmas-recipes exists and is not empty.
But that’s OK. It’s just upset because we’ve got that index.html file and possibly also a README.md in there that we made earlier. So move those onto your desktop for the moment and run the command again.
jekyll new /Users/Anna/Sites/christmas-recipes
It should say that the site has installed.
Check you’re in the repository, and if you’re not, navigate to it by typing cd , drag the christmas-recipes directory into terminal…
jekyll cd /Users/Anna/Sites/christmas-recipes
…and type this command to tell Jekyll to run:
jekyll serve --watch
By adding --watch at the end, we’re forcing Jekyll to rebuild the site every time we hit Save, so we don’t have to keep telling it to update every time we want to view the changes. We’ll need to run this every time we start work on the project, otherwise changes won’t be applied. For now, wait while it does its thing.
Update the config file
When it’s finished, we’ll see the text press ctrl-c to stop. Don’t do that, though. Instead, open up the directory. You’ll notice some new files and folders in there. There’s one called _site, and that’s where all the site files are saved when they’re turned into static HTML. Don’t touch the files in here — they’re the generated files and will get overwritten every time we make changes to pages and layouts.
There’s a file in our directory called _config.yml. This has some settings we can change, one of them being what our base URL is. GitHub Pages will assume the base URL is above the project repository, so changing the settings here will help further down the line when setting up navigation links.
Replace the contents of the _config.yml file with this:
name: Christmas Recipes
markdown: redcarpet
pygments: true
baseurl: /christmas-recipes
Set up your files
Overwrite the index.html file in the root with the one we made earlier (you might want to pop the README.md back in there, too).
Delete the files in the css folder — we’ll add our own later.
View the Jekyll site
Open up your favourite browser and type http://localhost:4000/christmas-recipes in the address bar.
Check it out, that’s your site! But it could do with a bit more love.
Set up the _includes files
It’s always useful to be able to pull in snippets of content onto pages, such as the header and footer, so they only need to be updated in one place. That’s what an _includes folder is for in Jekyll. Create a folder in the root called _includes, and within it add two files: head.html and foot.html.
In head.html, paste the following:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>{{ page.title }}</title>
<link rel="stylesheet" href="{{ site.baseurl }}/css/main.css" >
</head>
<body>
and in foot.html:
</body>
</html>
Whenever we want to pull in something from the _includes folder, we can use {% include filename.html %} in the layout file — I’ll show you how to set that up in next step.
Making layouts
In our directory, there’s a folder called _layouts and this lets us create a reusable template for pages. Inside that is a default.html file.
Delete everything in default.html and paste in this instead:
{% include head.html %}
<h1>{{ page.title }}</h1>
{{ content }}
{% include foot.html %}
That’s a very basic page with a header, footer, page title and some content. To apply this template to a page, go back into the index.html page and add this snippet to the very top of the file:
---
layout: default
title: Home
---
Now save the index.html file and hit Refresh in the browser. We should see a heading where {{ page.title }} was in the layout, which matches what comes after title: on the page itself (in this case, Home). So, if we wanted a subheading to appear on every page, we could add {{ page.subheading }} to where we want it to appear in our layout file, and a line that says subheading: This is a subheading in between the dashes at the top of the page itself.
Using Markdown for templates
Anything on a page that sits under the closing dashes is output where {{ content }} appears in the template file. At the moment, this is being output as HTML, but we can use Markdown instead, and Jekyll will convert that into HTML. For this recipe site, we want to make it as easy as possible for people to be able to collaborate, and also have the markup separate from the content, so let’s use Markdown instead of HTML for the recipes.
Telling a page to use Markdown instead of HTML is incredibly simple. All we need to do is change the filename from .html to .md, so let’s rename the index.html to index.md. Now we can use Markdown, and Jekyll will output that as HTML.
Create a new layout
We’re going to create a new layout called recipe which is going to be the template for any recipe page we create. Let’s keep it super simple.
In the _layouts folder, create a file called recipe.html and paste in this:
{% include head.html %}
<main>
<h1>{{ page.title }}</h1>
{{ content }}
<p>Recipe by <a href="{{ page.recipe-attribution-link }}">{{ page.recipe-attribution }}</a>.</p>
</main>
{% include nav.html %}
{% include foot.html %}
That’s our template. The content that goes on the recipe layout includes a page title, the recipe content, a recipe attribution and a recipe attribution link.
Adding some recipe pages
Create a new file in the root of the christmas-recipes folder and call it gingerbread.md. Paste the following into it:
---
layout: recipe
title: Gingerbread
recipe-attribution: HungryJenny
recipe-attribution-link: http://www.opensourcefood.com/people/HungryJenny/recipes/soft-christmas-gingerbread-cookies
---
Makes about 15 small cookies.
## Ingredients
* 175g plain flour
* 90g brown sugar
* 50g unsalted butter, diced, at room temperature
* 2 tbsp golden syrup
* 1 egg, beaten
* 1 tsp ground ginger
* 1 tsp cinnamon
* 1 tsp bicarbonate of soda
* Icing sugar to dust
## Method
1. Sift the flour, ginger, cinnamon and bicarbonate of soda into a large mixing bowl.
2. Use your fingers to rub in the diced butter. Mix in the sugar.
3. Mix the egg with the syrup then pour into the flour mixture. Fold in well to form a dough.
4. Tip some flour onto the work surface and knead the dough until smooth.
5. Preheat the oven to 180°C.
6. Roll the dough out flat and use a shaped cutter to make as many cookies as you like.
7. Transfer the cookies to a tray and bake in the oven for 15 minutes. Lightly dust the cookies with icing sugar.
The content is in Markdown, and when we hit Save, it’ll be converted into HTML in the _site folder. Save the file, and go to http://localhost:4000/christmas-recipes/gingerbread.html in your favourite browser.
As you can see, the Markdown content has been converted into HTML, and the attribution text and link has been inserted in the right place.
Add some navigation
In your _includes folder, create a new file called nav.html. Here is some code that will generate your navigation:
<nav class="nav-primary" role="navigation" >
<ul>
{% for p in site.pages %}
<li>
<a {% if p.url == page.url %}class="active"{% endif %} href="{{ site.baseurl }}{{ p.url }}">{{ p.title }}</a>
</li>
{% endfor %}
</ul>
</nav>
This is going to look for all pages and generate a list of them, and give the navigation item that is currently active a class of active so we can style it differently.
Now we need to include that navigation snippet in our layout. Paste {% include nav.html %} in default.html file, under {{ content }}.
Push the changes to GitHub Pages
Now we’ve got a couple of pages, it’s time to push our changes to GitHub. We can do this in exactly the same way as before. Check your special GitHub URL (your-username.github.io/your-project-name) and you should see your site up and running.
If you quit Terminal, don’t forget to run jekyll serve --watch from within the directory the next time you want to work on the files.
Next steps
Now we know the basics of creating Jekyll templates and publishing them as GitHub Pages, we can have some fun adding more pages and styling them up.
Here’s one I made earlier
I’ve only been using Jekyll for a matter of weeks, mainly for prototyping. It’s really good as a content management system for blogs, and a lot of people host their Jekyll blogs on GitHub, such as Harry Roberts
By hosting the code so openly it will make me take more pride in it and allow me to work on it much more easily; no excuses now!
Overall, the documentation for Jekyll feels a little sparse and geared more towards blogs than other sites, but as more people discover the benefits of it, I’m sure this will improve over time.
If you’re interested in poking about with some code, all the files from this tutorial are available on GitHub. |

Coding Towards Accessibility |
“Can we make it AAA-compliant?” – does this question strike fear into your heart? Maybe for no other reason than because you will soon have to wade through the impenetrable WCAG documentation once again, to find out exactly what AAA-compliant means?
I’m not here to talk about that.
The Web Content Accessibility Guidelines are a comprehensive and peer-reviewed resource which we’re lucky to have at our fingertips. But they are also a pig to read, and they may have contributed to the sense of mystery and dread with which some developers associate the word accessibility.
This Christmas, I want to share with you some thoughts and some practical tips for building accessible interfaces which you can start using today, without having to do a ton of reading or changing your tools and workflow.
But first, let’s clear up a couple of misconceptions.
Dreary, flat experiences
I recently built a front-end framework for the Post Office. This was a great gig for a developer, but when I found out about my client’s stringent accessibility requirements I was concerned that I’d have to scale back what was quite a complex set of visual designs.
Sites like Jakob Neilsen’s old workhorse useit.com and even the pioneering GOV.UK may have to shoulder some of the blame for this. They put a premium on usability and accessibility over visual flourish. (Although, in fairness to Mr Neilsen, his new site nngroup.com is really quite a snazzy affair, comparatively.)
Of course, there are other reasons for these sites’ aesthetics — and it’s not because of the limitations of the form. You can make an accessible site look as glossy or as plain as you want it to look. It’s always our own ingenuity and attention to detail that are going to be the limiting factors.
Synecdoche
We must always guard against the tendency to assume that catering to screen readers means we have the whole accessibility ballgame covered.
There’s so much more to accessibility than assistive technology, as you know. And within the field of assistive technology there are plenty of other devices for us to consider.
Planning to accommodate all these users and devices can be daunting. When I first started working in this field I thought that the breadth of technology was prohibitive. I didn’t even know what a screen reader looked like. (I assumed they were big and heavy, perhaps like an old typewriter, and certainly they would be expensive and difficult to fathom.) This is nonsense, of course. Screen reader emulators are readily available as browser extensions and can be activated in seconds. Chromevox and Fangs are both excellent and you should download one or the other right now.
But the really good news is that you can emulate many other types of assistive technology without downloading a byte. And this is where we move from misconceptions into some (hopefully) useful advice.
The mouse trap
The simplest and most effective way to improve your abilities as a developer of accessible interfaces is to unplug your mouse.
Keyboard operation has its own WCAG chapter, because most users of assistive technology are navigating the web using only their keyboards. You can go some way towards putting yourself into their shoes so easily — just by ditching a peripheral.
Learning this was a lightbulb moment for me. When I build interfaces I am constantly flicking between code and the browser, testing or viewing the changes I have made. Now, instead of checking a new element once, I check it twice: once with my mouse and then again without.
Don’t just :hover
The reality is that when you first start doing this you can find your site becomes unusable straightaway. It’s easy to lose track of which element is in focus as you hit the tab key repeatedly.
One of the easiest changes you can make to your coding practice is to add :focus and :active pseudo-classes to every hover state that you write. I’m still amazed at how many sites fail to provide a decent focus state for links (and despite previous 24 ways authors in 2007 and 2009 writing on this same issue!).
You may find that in some cases it makes sense to have something other than, or in addition to, the hover state on focus, but start with the hover state that your designer has taken the time to provide you with. It’s a tiny change and there is no downside. So instead of this:
.my-cool-link:hover {
background-color: MistyRose ;
}
…try writing this:
.my-cool-link:hover,
.my-cool-link:focus,
.my-cool-link:active {
background-color: MistyRose ;
}
I’ve toyed with the idea of making a Sass mixin to take care of this for me, but I haven’t yet. I worry that people reading my code won’t see that I’m explicitly defining my focus and active states so I take the hit and write my hover rules out longhand.
JavaScript can play, too
This was another revelation for me. Keyboard-only navigation doesn’t necessitate a JavaScript-free experience, and up-to-date screen readers can execute JavaScript. So we’re able to create complex JavaScript-driven interfaces which all users can interact with.
Some of the hard work has already been done for us. First, there are already conventions around keyboard-driven interfaces. Think about the last time you viewed a photo album on Facebook. You can use the arrow keys to switch between photos, and the escape key closes whichever lightbox-y UI thing Facebook is showing its photos in this week. Arrow keys (up/down as well as left/right) for progression through content; Escape to back out of something; Enter or space bar to indicate a positive intention — these are established keyboard conventions which we can apply to our interfaces to improve their accessiblity.
Of course, by doing so we are improving our interfaces in general, giving all users the option to switch between keyboard and mouse actions as and when it suits them.
Second, this guy wants to help you out. Hans Hillen is a developer who has done a great deal of work around accessibility and JavaScript-powered interfaces. Along with The Paciello Group he has created a version of the jQuery UI library which has been fully optimised for keyboard navigation and screen reader use. It’s a fantastic reference which I revisit all the time
I’m not a huge fan of the jQuery UI library. It’s a pain to style and the code is a bit bloated. So I’ve not used this demo as a code resource to copy wholesale. I use it by playing with the various components and seeing how they react to keyboard controls. Each component is also fully marked up with the relevant ARIA roles to improve screen reader announcement where possible (more on this below).
Coding for accessibility promotes good habits
This is a another observation around accessibility and JavaScript. I noticed an improvement in the structure and abstraction of my code when I started adding keyboard controls to my interface elements.
Your code has to become more modular and event-driven, because any number of events could trigger the same interaction. A mouse-click, the Enter key and the space bar could all conceivably trigger the same open function on a collapsed accordion element. (And you want to keep things DRY, don’t you?)
If you aren’t already in the habit of separating out your interface functionality into discrete functions, you will be soon.
var doSomethingCool = function(){
// Do something cool here.
}
// Bind function to a button click - pretty vanilla
$('.myCoolButton').on('click', function(){
doSomethingCool();
return false;
});
// Bind the same function to a range of keypresses
$(document).keyup(function(e){
switch(e.keyCode) {
case 13: // enter
case 32: // spacebar
doSomethingCool();
break;
case 27: // escape
doSomethingElse();
break;
}
});
To be honest, if you’re doing complex UI stuff with JavaScript these days, or if you’ve been building any responsive interfaces which rely on JavaScript, then you are most likely working with an application framework such as Backbone, Angular or Ember, so an abstraced and event-driven application structure will be familar to you. It should be super easy for you to start helping out your keyboard-only users if you aren’t already — just add a few more event bindings into your UI layer!
Manipulating the tab order
So, you’ve adjusted your mindset and now you test every change to your codebase using a keyboard as well as a mouse. You’ve applied all your hover states to :focus and :active so you can see where you’re tabbing on the page, and your interactive components react seamlessly to a mixture of mouse and keyboard commands. Feels good, right?
There’s another level of optimisation to consider: manipulating the tab order. Certain DOM elements are naturally part of the tab order, and others are excluded. Links and input elements are the main elements included in the tab order, and static elements like paragraphs and headings are excluded. What if you want to make a static element ‘tabbable’?
A good example would be in an expandable accordion component. Each section of the accordion should be separated by a heading, and there’s no reason to make that heading into a link simply because it’s interactive.
<div class="accordion-widget">
<h3>Tyrannosaurus</h3>
<p>Tyrannosaurus; meaning "tyrant lizard"...<p>
<h3>Utahraptor</h3>
<p>Utahraptor is a genus of theropod dinosaurs...<p>
<h3>Dromiceiomimus</h3>
<p>Ornithomimus is a genus of ornithomimid dinosaurs...<p>
</div>
Adding the heading elements to the tab order is trivial. We just set their tabindex attribute to zero. You could do this on the server or the client. I prefer to do it with JavaScript as part of the accordion setup and initialisation process.
$('.accordion-widget h3').attr('tabindex', '0');
You can apply this trick in reverse and take elements out of the tab order by setting their tabindex attribute to −1, or change the tab order completely by using other integers. This should be done with great care, if at all. You have to be sure that the markup you remove from the tab order comes out because it genuinely improves the keyboard interaction experience. This is hard to validate without user testing. The danger is that developers will try to sweep complicated parts of the UI under the carpet by taking them out of the tab order. This would be considered a dark pattern — at least on my team!
A farewell ARIA
This is where things can get complex, and I’m no expert on the ARIA specification: I feel like I’ve only dipped my toe into this aspect of coding for accessibility. But, as with WCAG, I’d like to demystify things a little bit to encourage you to look into this area further yourself.
ARIA roles are of most benefit to screen reader users, because they modify and augment screen reader announcements.
Let’s take our dinosaur accordion from the previous section. The markup is semantic, so a screen reader that can’t handle JavaScript will announce all the content within the accordion, no problem.
But modern screen readers can deal with JavaScript, and this means that all the lovely dino information beneath each heading has probably been hidden on document.ready, when the accordion initialised. It might have been hidden using display:none, which prevents a screen reader from announcing content. If that’s as far as you have gone, then you’ve committed an accessibility sin by hiding content from screen readers. Your user will hear a set of headings being announced, with no content in between. It would sound something like this if you were using Chromevox:
> Tyrannosaurus. Heading Three.
> Utahraptor. Heading Three.
> Dromiceiomimus. Heading Three.
We can add some ARIA magic to the markup to improve this, using the tablist role. Start by adding a role of tablist to the widget, and roles of tab and tabpanel to the headings and paragraphs respectively. Set boolean values for aria-selected, aria-hidden and aria-expanded. The markup could end up looking something like this.
<div class="accordion-widget" role="tablist">
<!-- T-rex -->
<h3 role="tab"
tabindex="0"
id="tab-2"
aria-controls="panel-2"
aria-selected="false">Utahraptor</h3>
<p role="tabpanel"
id="panel-2"
aria-labelledby="tab-2"
aria-expanded="false"
aria-hidden="true">Utahraptor is a genus of theropod dinosaurs...</p>
<!-- Dromiceiomimus -->
</div>
Now, if a screen reader user encounters this markup they will hear the following:
> Tyrannosaurus. Tab not selected; one of three.
> Utahraptor. Tab not selected; two of three.
> Dromiceiomimus. Tab not selected; three of three.
You could add arrow key events to help the user browse up and down the tab list items until they find one they like.
Your accordion open() function should update the ARIA boolean values as well as adding whatever classes and animations you have built in as standard. Your users know that unselected tabs are meant to be interacted with, so if a user triggers the open function (say, by hitting Enter or the space bar on the second item) they will hear this:
> Utahraptor. Selected; two of three.
The paragraph element for the expanded item will not be hidden by your CSS, which means it will be announced as normal by the screen reader.
This kind of thing makes so much more sense when you have a working example to play with. Again, I refer you to the fantastic resource that Hans Hillen has put together: this is his take on an accessible accordion, on which much of my example is based.
Conclusion
Getting complex interfaces right for all of your users can be difficult — there’s no point pretending otherwise. And there’s no substitute for user testing with real users who navigate the web using assistive technology every day. This kind of testing can be time-consuming to recruit for and to conduct. On top of this, we now have accessibility on mobile devices to contend with. That’s a huge area in itself, and it’s one which I have not yet had a chance to research properly.
So, there’s lots to learn, and there’s lots to do to get it right. But don’t be disheartened. If you have read this far then I’ll leave you with one final piece of advice: don’t wait.
Don’t wait until you’re building a site which mandates AAA-compliance to try this stuff out. Don’t wait for a client with the will or the budget to conduct the full spectrum of user testing to come along. Unplug your mouse, and start playing with your interfaces in a new way. You’ll be surprised at the things that you learn and the issues you uncover.
And the next time an true accessibility project comes along, you will be way ahead of the game. |

How to Write a Book |
Were you recently inspired to write a book after reading Owen Gregory’s compendium of author insights? Maybe so inspired to strike out on your own and self-publish?
Based on personal experience, writing a book is hard. It requires a great deal of research, experience, and patience. To be able to consolidate your thoughts and what you’ve learned into a sensible and readable tome is an admirable feat. To decide to self-publish and take on yourself all of the design, printing, distribution, and so much more is tantamount to insanity. Again, based on personal experience.
So, why might you want to self-publish?
If you’ve spent many a late night doing cross-browser testing just to know that your site works flawlessly in twenty-four different browsers — including Mosaic, of course — then maybe you’ll understand the fun that comes from doing it all.
Working with a publisher, you’re left to focus on one core thing: writing. That’s a good thing. A good publisher has the right resources to help you get your idea polished and the distribution network to get your book on store shelves around the world. It’s a very proud moment to be able to walk into a book store and see your book sitting there on the shelf.
Self-publishing can also be a wonderful process as you get to own it from beginning to end. Every decision is yours and if you’re a control freak like me, this can be a very rewarding experience.
While there are many aspects to self-publishing, I’m going to speak to just one of them: creating an ebook.
Formats
In creating an ebook, you first need to decide what formats you wish to support. There are three main formats, each with their own pros and cons:
PDF
EPUB
MOBI
PDFs are supported on almost every device (Windows, Mac, Kindle, iPad, Android, etc.) and can even be a stepping stone to creating a print version of your book. PDFs allow for full typographic and design control, but at the cost of needing to fit things into a predefined page layout. Is it US Letter or A4? Or is it a format that isn’t easily printed by readers on their home printers?
EPUB is a more fluid format that is supported by the Apple iPad, iPhone, and now on the desktop with OS X Mavericks. It’s also supported by Google Play for Android devices. While EPUB is supported on other devices, you’re likely to choose EPUB because you’re targeting your book at the Apple audience. The EPUB format is HTML-based with support for some CSS and even video and interactive elements. You can create very rich and exciting experiences using the EPUB format that just aren’t possible with PDF or MOBI. However, if you decide to support multiple file formats, you’ll likely find — as I did — that a consistent experience between all formats is easier to build and maintain, and therefore the extra benefits of interactivity go out the window.
MOBI is a format originally developed for the Mobipocket Reader but more popularly supported by the Amazon Kindle. If you’re looking to attract the Kindle audience or publish to Amazon via the Kindle Direct Publishing platform then the HTML-based MOBI format is the format you’ll want to go with.
Distribution will probably factor in heavily with what format you decide to go with. Many people I know who self-publish go with PDF only due to its ubiquity.
If you want to garner a wider audience by distributing via Amazon or the iBookstore then you’ll need to think about supporting all three formats (as I did).
What tools should I use?
I spent a lot of time figuring out the right toolset and finally got something that suits me just right.
In the past, when working with a publisher, I was given a Microsoft Word template that was passed back and forth between myself, the editor, and tech reviewer. This template has been the bane of any book writer that I’ve spoken to. Not every publisher is like that, though. Some publishers, like O’Reilly, use DocBook, an XML-based format that can be converted into PDF, EPUB, and MOBI.
Publishers already have a style guide and whether it’s DocBook or a Word template, they have the tools already in place to easily convert your work into multiple formats.
Self-publishing means that you’ll likely have to do a lot of tweaking to get things looking and working the way you want them to. I tried DocBook and the open source export tools didn’t create HTML to my liking. Fixing even the most mundane things required fiddling with XSL transformations for hours on end. Not the way I like to spend my time. I can only imagine the hoops I would’ve had to go through to get a PDF to look half-decent.
Tools like Pages or Scrivener offer up the ability to publish to multiple formats, too, but none offered me the control over the output that I truly desired. Have a mentioned that I’m a control freak?
I ended up writing my book using a technology that I already knew quite well: HTML. By writing in HTML, I already had something that I could post on my website, use for the EPUB and use for the MOBI format. All without having to change a thing. (That’s right: the same HTML that is used on SMACSS.com is used in the EPUB and is used in the MOBI.)
What about PDF? I could open up the HTML in a web browser, choose Save as PDF and be done with it but let’s face it: the filename and date attached to every single page doesn’t exactly scream professional. Web browsers actually do a surprisingly poor job with supporting the CSS paged media spec.
I had resorted to copying and pasting the content into Pages and saving as PDF from there. It wasn’t elegant but it worked. However, any changes to my HTML source required redoing those changes in Pages, as well.
Then I met my Prince Charming: Prince XML. It’s pricey but it works incredibly well. It takes HTML and CSS (that very format I’ve been using for all of my other file formats) and will generate a PDF via a command line interface. Prince supports CSS paged media including headers, footers, page counts, and alternating page styles.
From one format, HTML, I can now easily publish to PDF, MOBI, and EPUB, and even my website. I use the PDF version to send to the printer along with cover art to be bound and ready to ship around the world. It’s amazing how versatile HTML (and CSS) is.
To learn more about writing books with HTML and CSS, I recommend reading Building Books with CSS3 over at A List Apart.
Creating an EPUB
Let’s take a step back. Prince gets us from HTML to PDF but how do we make an EPUB out of the HTML?
An EPUB file is essentially a ZIP file with a renamed extension. There are some core files that you need to start with:
Root
META-INF
container.xml
mimetype
content.opf
toc.ncx
After that, you can start adding your content to the project. Be sure to update the toc.ncx (Table of Contents) and content.opf (the ebook manifest) with any changes you make to your project.
You can learn more about the file formats with the EPUB Format Construction Guide.
Once all your files are in place, you’ll need to create the EPUB file by running two commands (on OS X, at least):
zip -X0 your-ebook.epub mimetype
zip -Xur9D your-ebook.epub *
The mimetype needs to be the first file inside the ZIP file and therefore gets added first. Then, the rest of the files are added.
I’ve added a function to my .bash_profile to make this even easier:
function epub()
{
zip -q0X $@ mimetype; zip -qXr9D $@ *
}
Then, within the folder from which I want to create an ebook, I just run epub your-ebook.epub from the Terminal command line and the EPUB file should be ready to go.
Creating the MOBI
We have our EPUB and we have our PDF. The last step is the MOBI file. For this, I call upon Calibre. Calibre can be used as a reader and as a library but I use it exclusively to export my EPUB files to MOBI.
Calibre includes a command line utility to convert from EPUB to MOBI. (To install the command line tools, go to Preferences > Advanced > Miscellaneous and click Install Command Line Tools.)
ebook-convert your-ebook.epub your-ebook.mobi
Spread the joy
Now that you have all of your different file formats, you need to get them into the hands of people who want to (ho-ho-hopefully) buy your book!
There are a number of marketplaces such as Amazon’s Kindle Direct Publishing, iBookstore, Google Play, and NOOK Press.
Some publishers, like PragProg and O’Reilly will also add self-published books to their roster if they feel it’s a good fit for their audience.
With any distribution, you’ll have to give up a percentage of your sales—from 30% to 70% of each sale, so consider your options wisely.
Of course, you can always open your own online store and reap as much of the revenue as possible, assuming you can get the traffic to your site. Handling your own distribution allows you to create a deeper one-on-one connection with your customers, something that is impossible with other distribution channels since you don’t get customer information through other services—even though you are giving them a huge chunk of your sales!
Go forth and prosper
There’s a lot of thought and time that goes into writing a book and just as much thought and time can go into creating, publishing, and marketing your book once you’re done.
In the end, self-publishing can be a very rewarding process and well worth the time that goes into it. |

Home Kanban for Domestic Bliss |
My wife is an architect. I’m a leader of big technical teams these days, but for many years after I was a dev I was a project/program manager. Our friends and family used to watch Grand Designs and think that we would make the ideal team — she could design, I could manage the project of building or converting whatever dream home we wanted.
Then we bought a house.
A Victorian terrace in the north-east of England that needed, well, a fair bit of work. The big decisions were actually pretty easy: yes, we should knock through a double doorway from the dining room to the lounge; yes, we should strip out everything from the utility room and redo it; yes, we should roll back the hideous carpet in the bedrooms upstairs and see if we could restore the original wood flooring.
Those could be managed like a project.
What couldn’t be was all the other stuff. Incremental improvements are harder to schedule, and in a house that’s over a hundred years old you never know what you’re going to find when you clear away some tiles, or pull up the carpets, or even just spring-clean the kitchen (“Erm, hon? The paint seems to be coming off. Actually, so does the plaster…”). A bit like going in to fix bugs in code or upgrade a machine — sometimes you end up quite far down the rabbit hole.
And so, as we tried to fit in those improvements in our evenings and weekends, we found ourselves disagreeing. Arguing, even. We were both trying to do the right thing (make the house better) but since we were fitting it in where we could, we often didn’t get to talk and agree in detail what was needed (exactly how to make the house better). And it’s really frustrating when you stay up late doing something, just to find that your other half didn’t mean that they meant this instead, and so your effort was wasted.
Then I saw this tweet from my friend and colleague Jamie Arnold, who was using the same kanban board approach at home as we had instituted at the UK Government Digital Service to manage our portfolio.
Mrs Arnold embraces Kanban wall at home. Disagreements about work in progress and priority significantly reduced.. ;) pic.twitter.com/407brMCH— Jamie Arnold (@itsallgonewrong) October 27, 2012
And despite Jamie’s questionable taste in fancy dress outfits (look closely at that board), he is a proper genius when it comes to processes and particularly agile ones. So I followed his example and instituted a home kanban board.
What is this kanban of which you speak?
Kanban boards are an artefact from lean manufacturing — basically a visualisation of a production process. They are used to show you where your bottlenecks are, or where one part of the process is producing components faster than another part of the process can cope. Identifying the bottlenecks leads you to set work in progress (WIP) limits, so that you get an overall more efficient system.
Increasingly kanban is used as an agile software development approach, too, especially where support work (like fixing bugs) needs to be balanced with incremental enhancement (like adding new features).
I’m a big advocate of kanban when you have a system that needs to be maintained and improved by the same team at the same time. Rather than the sprint-based approach of scrum (where the next sprint’s stories or features to be delivered are agreed up front), kanban lets individuals deal with incidents or problems that need investigation and bug fixing when urgent and important. Then, when someone has capacity, they can just go to the board and pull down the next feature to develop or test.
So, how did we use it?
One of the key tenets of kanban is that you visualise your workflow, so we put together a whiteboard with columns: Icebox; To Do Next; In Process; Done; and also a section called Blocked. Then, for each thing that needed to happen in the house, we put it on a Post-it note and initially chucked them all in the Icebox — a collection with no priority assigned yet.
Each week we looked at the Icebox and pulled out a set of things that we felt should be done next. This was pulled into the To Do Next column, and then each time either of us had some time, we could just pull a new thing over into the In Process column. We agreed to review at the end of each week and move things to Done together, and to talk about whether this kanban approach was working for us or not.
We quickly learned for ourselves why kanban has WIP limits as a key tenet — it’s tempting to pull everything into the To Do Next column, but that’s unrealistic. And trying to do more than one or two things each at a given time isn’t terribly productive owing to the cost of task switching. So we tend to limit our To Do Next to about seven items, and our In Process to about four (a max of two each, basically).
We use the Blocked column when something can’t be completed — perhaps we can’t fix something because we discovered we don’t have the required tools or supplies, or if we’re waiting for a call back from a plumber. But it’s nice to put it to one side, knowing that it won’t be forgotten.
What helped the most?
It wasn’t so much the visualisation that helped us to see what we needed to do, but the conversation that happened when we were agreeing priorities, moving them to In Process and then on to Done made the biggest difference. Getting clear on the order of importance really is invaluable — as is getting clear on what Done really means!
The Blocked column is also great, as it helps us keep track of things we need to do outside the house to make sure we can make progress. We also found it really helpful to examine the process itself and figure out whether it was working for us. For instance, one thing we realised is it’s worth tracking some regular tasks that need time invested in them (like taking recycling that isn’t picked up to the recycling centre) and these used to cycle around and around. So they were moved to Done as part of our weekly review, but then immediately put back in the Icebox to float back to the top again at a relevant time.
But the best thing of all? That moment where we get to mark something as done! It’s immensely satisfying to review at the end of the week and have a physical marker of the progress you’ve made.
All in all, a home kanban board turned out to be a very effective way to pull tasks through stages rather than always trying to plan them out in advance, and definitely made collaboration on our home tasks significantly smoother. Give it a try! |

JavaScript: Taking Off the Training Wheels |
JavaScript is the third pillar of front-end web development. Of those pillars, it is both the most powerful and the most complex, so it’s understandable that when 24 ways asked, “What one thing do you wish you had more time to learn about?”, a number of you answered “JavaScript!”
This article aims to help you feel happy writing JavaScript, and maybe even without libraries like jQuery. I can’t comprehensively explain JavaScript itself without writing a book, but I hope this serves as a springboard from which you can jump to other great resources.
Why learn JavaScript?
So what’s in it for you? Why take the next step and learn the fundamentals?
Confidence with jQuery
If nothing else, learning JavaScript will improve your jQuery code; you’ll be comfortable writing jQuery from scratch and feel happy bending others’ code to your own purposes. Writing efficient, fast and bug-free jQuery is also made much easier when you have a good appreciation of JavaScript, because you can look at what jQuery is really doing. Understanding how JavaScript works lets you write better jQuery because you know what it’s doing behind the scenes. When you need to leave the beaten track, you can do so with confidence.
In fact, you could say that jQuery’s ultimate goal is not to exist: it was invented at a time when web APIs were very inconsistent and hard to work with. That’s slowly changing as new APIs are introduced, and hopefully there will come a time when jQuery isn’t needed.
An example of one such change is the introduction of the very useful document.querySelectorAll. Like jQuery, it converts a CSS selector into a list of matching elements. Here’s a comparison of some jQuery code and the equivalent without.
$('.counter').each(function (index) {
$(this).text(index + 1);
});
var counters = document.querySelectorAll('.counter');
[].slice.call(counters).forEach(function (elem, index) {
elem.textContent = index + 1;
});
Solving problems no one else has!
When you have to go to the internet to solve a problem, you’re forever stuck reusing code other people wrote to solve a slightly different problem to your own. Learning JavaScript will allow you to solve problems in your own way, and begin to do things nobody else ever has.
Node.js
Node.js is a non-browser environment for running JavaScript, and it can do just about anything! But if that sounds daunting, don’t worry: the Node community is thriving, very friendly and willing to help.
I think Node is incredibly exciting. It enables you, with one language, to build complete websites with complex and feature-filled front- and back-ends. Projects that let users log in or need a database are within your grasp, and Node has a great ecosystem of library authors to help you build incredible things. Exciting!
Here’s an example web server written with Node. http is a module that allows you to create servers and, like jQuery’s $.ajax, make requests. It’s a small amount of code to do something complex and, while working with Node is different from writing front-end code, it’s certainly not out of your reach.
var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello World');
}).listen(1337);
console.log('Server running at http://localhost:1337/');
Grunt and other website tools
Node has brought in something of a renaissance in tools that run in the command line, like Yeoman and Grunt. Both of these rely heavily on Node, and I’ll talk a little bit about Grunt here.
Grunt is a task runner, and many people use it for compiling Sass or compressing their site’s JavaScript and images. It’s pretty cool. You configure Grunt via the gruntfile.js, so JavaScript skills will come in handy, and since Grunt supports plug-ins built with JavaScript, knowing it unlocks the bucketloads of power Grunt has to offer.
Ways to improve your skills
So you know you want to learn JavaScript, but what are some good ways to learn and improve? I think the answer to that is different for different people, but here are some ideas.
Rebuild a jQuery app
Converting a jQuery project to non-jQuery code is a great way to explore how you modify elements on the page and make requests to the server for data. My advice is to focus on making it work in one modern browser initially, and then go cross-browser if you’re feeling adventurous. There are many resources for directly comparing jQuery and non-jQuery code, like Jeffrey Way’s jQuery to JavaScript article.
Find a mentor
If you think you’d work better on a one-to-one basis then finding yourself a mentor could be a brilliant way to learn. The JavaScript community is very friendly and many people will be more than happy to give you their time. I’d look out for someone who’s active and friendly on Twitter, and does the kind of work you’d like to do. Introduce yourself over Twitter or send them an email. I wouldn’t expect a full tutoring course (although that is another option!) but they’ll be very glad to answer a question and any follow-ups every now and then.
Go to a workshop
Many conferences and local meet-ups run workshops, hosted by experts in a particular field. See if there’s one in your area. Workshops are great because you can ask direct questions, and you’re in an environment where others are learning just like you are — no need to learn alone!
Set yourself challenges
This is one way I like to learn new things. I have a new thing that I’m not very good at, so I pick something that I think is just out of my reach and I try to build it. It’s learning by doing and, even if you fail, it can be enormously valuable.
Where to start?
If you’ve decided learning JavaScript is an important step for you, your next question may well be where to go from here.
I’ve collected some links to resources I know of or use, with some discussion about why you might want to check a particular site out. I hope this serves as a springboard for you to go out and learn as much as you want.
Beginner
If you’re just getting started with JavaScript, I’d recommend heading to one of these places. They cover the basics and, in some cases, a little more advanced stuff. They’re all reputable sources (although, I’ve included something I wrote — you can decide about that one!) and will not lead you astray.
jQuery’s JavaScript 101 is a great first resource for JavaScript that will give you everything you need to work with jQuery like a pro.
Codecademy’s JavaScript Track is a small but useful JavaScript course. If you like learning interactively, this could be one for you.
HTMLDog’s JavaScript Tutorials take you right through from the basics of code to a brief introduction to newer technology like Node and Angular. [Disclaimer: I wrote this stuff, so it comes with a hazard warning!]
The tuts+ jQuery to JavaScript mentioned earlier is great for seeing how jQuery code looks when converted to pure JavaScript.
Getting in-depth
For more comprehensive documentation and help I’d recommend adding these places to your list of go-tos.
MDN: the Mozilla Developer Network is the first place I go for many JavaScript questions. I mostly find myself there via a search, but it’s a great place to just go and browse.
Axel Rauschmayer’s 2ality is a stunning collection of articles that will take you deep into JavaScript. It’s certainly worth looking at.
Addy Osmani’s JavaScript Design Patterns is a comprehensive collection of patterns for writing high quality JavaScript, particularly as you (I hope) start to write bigger and more complex applications.
And finally…
I think the key to learning anything is curiosity and perseverance. If you have a question, go out and search for the answer, even if you have no idea where to start. Keep going and going and eventually you’ll get there. I bet you’ll learn a whole lot along the way. Good luck!
Many thanks to the people who gave me their time when I was working on this article: Tom Oakley, Jack Franklin, Ben Howdle and Laura Kalbag. |

Untangling Web Typography |
When I was a carpenter, I noticed how homeowners often had this deer-in-the-headlights look when the contractor I worked for would ask them to make tons of decisions, seemingly all at once.
Square or subway tile? Glass or ceramic? Traditional or modern trim details? Flat face or picture frame cabinets? Real wood or laminate flooring? Every day the decisions piled up and were usually made in the context of that room, or that part of that room. Rarely did the homeowner have the benefit of taking that particular decision in full view of the larger context of the project. And architectural plans? Sure, they lay out the broad strokes, but there is still so much to decide.
Typography is similar. Designers try to make sites that are easy to use and understand visually. They labour over the details of line height, font size, line length, and font weights. They consider the relative merits of different typographical scales for applications versus content-driven sites. Frequently, designers consider all of this in the context of one page, feature, or view of an application. They are asked to make a million tiny decisions.
Sometimes designers just bump up the font size until it looks right.
I don’t see anything wrong with that. Instincts are important. Designing in context is easier. It’s OK to leave the big picture until later. Design a bunch of things, and then look for the patterns. You can’t always know everything up front. How does the current feature relate to all the other features on the site? For a large site, just like for a substantial remodel, the number of decisions you would need to internalize to make that knowable would be prohibitively large.
When typography goes awry
I should be honest. I know very little about typography. I struggle to understand vertical rhythm and the math in Tim Ahrens’s talks about the interaction between type design and rendering technology kind of melted my brain. I have an unusual perspective because I’m not the one making the design decisions, but I am the one implementing them and often cleaning up when a project goes off the rails.
I’ve seen projects with thousands of font-size declarations and headings. One project even had over ten thousand margin declarations. So while I appreciate creative exploration, I’m also eager to establish patterns in typography and make sure we aren’t choosing not to choose. Or, choosing all the things.
Analyzing a site’s typography
Most of my projects start out with an evaluation of the client’s existing CSS. I look for duplication in the CSS by using Grep, though functionality is landing soon in CSS Lint to do the same thing automatically. The goal is to find the underlying missing abstractions that, once in place, would allow developers to create new functionality without needing to write additional CSS. In addition to that, my team and I would comb through each site (generally, around ten pages is enough to get the big picture), and take screenshots of each of the components we found.
In this way, we could look for subtle visual differences that were unlikely to add value to the user. By correcting these differences, we could help make the design more consistent, and at the same time the code leaner and more performant. Typography is much like a homeowner who chooses to incorporate too many disparate design elements, pairing a mid-century modern sofa with flowered country cottage curtains. Often the typography of a site ends up collecting an endless array of new typefaces as the site’s overall styles evolve. Designers come and go on a project, and eventually no one can remember how the 16px Verdana got into the codebase.
Automation
We used to do this work by hand. It was incredibly tedious. We’d go through the site, taking screenshots and meticulously documenting the style information we found. We didn’t have to do that many times before it became incredibly clear that the task needed to be automated. So we built a little tool called the Type-o-matic that could do it for us.
To try it on your site:
Download and install the Firebug extension to Firefox
Download and install the Type-o-matic extension to Firebug (I know, I fully intend to port it to Chrome)
Now, visit the site you’d like to test
Right click and choose Inspect element with Firebug
Now click on the Typography tab
Click Persist
Click Generate Report
Choose which pages to analyze (we’ve found that ten is a good number to get the big picture, but you can analyze as many as you’d like — it will even work on just one page!)
Now navigate to other pages, and on each subsequent page, click Generate Report
The table of results can be a bit difficult to interact with, so you can always click Copy to clipboard, and copy the results (JSON).
A screenshot of Type-o-matic in action
What does this data mean?
When you’ve analyzed as many pages or different views as you’d like, you’ll start to see some interesting patterns emerge in the data. In the right-hand column, you’ll see examples of how each kind of typography we found has been used in a real context on your site. It is organized by color and then by size so you can easily see how you are using typography.
The next thing you’ll want to take a look at is in the first column, called “Count”. We’ve counted how many times you’ve used each combination of typographical styles. This can be incredibly helpful when deciding which styles were intentional, versus one-off color pick errors or experiments that never got removed from the code base. If you’ve used one color blue 1,400 times, and another just 23, it’s pretty obvious which is more in line with broader site-wide styles.
Consistency before perfection
It can be really tempting to try to make everything perfect — to try to make every decision final. When you use the data you can collect from this tool, I’d recommend trying to get to consistent before you try to make things perfect. Stop using fifteen different shades of blue type first, and then if you want to change to a new blue, go for it! You’ll be able to make design changes much more easily once you’ve reduced the total number of typographical styles you rely on.
Lower the importance of the decisions you are making. Our sites, like ourselves, are always a work in progress. Or, as a carpenter I used to work with said, “You’re not building a fucking piano.” We’re not building houses. We can choose one typeface today and a different one tomorrow. It is OK to experiment. Be brave. |

Data-driven Design with an Annual Survey |
Too often, we base designs on assumptions that don’t match customer perspectives. Why? Because the data we need to make informed decisions isn’t available.
Imagine starting off the year with a treasure trove of user data that can be filtered, sliced, and diced to inform new UI designs, help you discover where users struggle the most, and expose emerging trends in your customers’ needs that could lead to new features. Why, that would be useful indeed. And it’s easy to obtain by conducting an annual survey.
Annual surveys may seem as exciting as receiving socks and undies for Christmas, but they’re the gift that keeps on giving all year long (just like fresh socks and undies). I’m not ashamed to admit it: I love surveys! Each time my design research team runs a survey, we learn so much about customer motivations, interests, and behaviors.
Surveys provide an aggregate snapshot of your users that can’t easily be obtained by other research methods, and they can be conducted quickly too. You can build a survey in a few hours, run a pilot test in a day, and have real results streaming in the following day. Speed is essential if design research is going to keep pace with a busy product release schedule.
Surveys are also an invaluable springboard for customer interviews, which provide deep perspectives on user behavior. If you play your cards right as you construct your survey, you can capture a user ID and an email address for each respondent, making it easy to get in touch with customers whose feedback is particularly intriguing. No more recruiting customers for your research via Twitter or through a recruiting company charging a small fortune. You can filter survey responses and isolate the exact customers to talk with in moments, not months.
I love this connected process of sending targeted surveys, filtering the results, and then — with surgical precision — selecting just the right customers to interview. Not only is it fast and cheap, but it lets design researchers do quantitative and qualitative research in a coordinated way. Aggregate survey responses help you quantify the perspectives of different user segments, and interviews help you get into the heads of your customers.
An annual survey can give your team the data needed to make more informed designs in the new year. It all starts with a plan.
Planning your survey
Before you start jotting down questions to ask users, spend some time thinking about the work your team will be doing in the coming year. Are you planning new mobile apps or a responsive redesign? Then questions about devices used and behaviors around mobile devices might be in order. Rethinking your content strategy? Then you might want to ask a few questions about how your customers consume content.
You can’t predict all of the projects you’ll be working on in the coming year, but tuck a couple of sections in your survey about the projects you’re certain about. This will give you the research you need to start new projects with solid foundational data.
Google Drive is a great place to start collaboratively building survey questions with colleagues. Questions that seem crystal clear in your head get challenged, refined, or even expanded quickly when the entire team can chime in.
As you craft your survey, try to consider how you’ll filter it once all of the data is compiled. Do you need to see responses by industry, by age of an account, by devices used, or by size of company? Adding the right filter questions can help you discover fascinating patterns in user segments. Filtering on responses to a few questions can surface insights like: customers in non-profit companies with more than 100 employees are 17% more likely to use an Android phone and are most attracted to features A, D, and F. A designer working on the landing page for a non-profit would love to have concrete information like this. Filter questions are key, so consider them carefully. But don’t go overboard — too many of them and you’ll start to hurt your survey response rate.
Multiple choice questions are the heart of most surveys because respondents can complete them quickly, which increases response rate, and researchers can analyze them without a lot of manual categorization. Open text field questions are valuable too, but be careful not to add too many to your survey. You’ll hate yourself after the survey’s done and you have to sort through and tag thousands of open responses so patterns become visible. Oy vey!
An open-ended question works well towards the end of the survey. At this point respondents have a lot of topics swirling around in their head and tend to say weird things that will pique your interest. This is where you’ll find the outliers who are using your product. They’ll be fascinating to interview, and on occasion will help you see your work in a brand new way.
Conclude your survey with a question asking permission to get in touch for a followup interview so you don’t pester people who want to be left alone.
With your questions nailed down, it’s time to build out that survey and get it ready for sending!
Building your survey
There are dozens of apps you could use to build your survey, but SurveyMonkey is the one that I prefer. It lets you pass in variables for each respondent such as user ID and email address. Metadata about respondents is essential if you’re going to do any follow-up interviews with your customers in the coming year. SurveyMonkey also makes it easy to set up question logic, showing questions to customers only if they responded in a certain way to a prior question. This helps you avoid asking irrelevant questions to some respondents.
Determining survey recipients
Once you’ve chosen a survey tool and entered all of your questions, you need to gather a list of recipients. Your first instinct will be to send it to everyone. You might say, “I need maximum response and metric shit tons of data!” But this is rarely the best approach — broad distribution almost always leads to lower response rates, increased noise, and decreased signal in your data. Are there subsets of customers you could send to, like only those who are active, those who are paying, or have been with you for a certain length of time? Talk to the keepers of your customer database and see how they can segment it so you can be certain you’re talking to just the people who will have the most relevant responses for your needs.
If you want to get super nerdy when finding the right customer sample to survey, use a [sample size calculator]. Sampling is a deep subject best explored in other articles.
Crafting your survey email
After focusing your energies on writing and building your survey, the email asking your customers to respond seems almost trivial, but it will greatly influence your response rate. Take great care when writing your subject line and the body of the email. If you can pull it off, A/B testing subject lines can greatly improve the open rate of your email and click-through to your survey. My design research team has seen a ~10% increase in open and click rates when we A/B tested. We’ve found that personalizing subject lines and greetings with the recipients name (ie. “Hey, Aarron. How can we make our app work better for you?”) gave us the best response rates. Your mileage may vary.
The tone of your email is important — be friendly, honest, and to the point. Those that are passionate about your product will be happy to share their perspective. Writing a survey email that people will actually respond to ain’t easy — in fact, they’re almost always annoying. But Ben Chestnut found a non-annoying way to send a survey email and improve response rates.
The email sent for the 2013 MailChimp survey let customers know what we’d been up to in the previous year, and invited feedback on what we should work on in the coming year.
The link to your survey should be a clear call to action. A big button with a label like “Answer a few questions” generally does the trick. The URL linking to the survey will need to include some variables like user ID and email. It might look something like this if you’re using SurveyMonkey:
http://surveymonkey.com/s/somesurveyid/?uid=*|UID|*&email=*|email|*
As each email is sent, the proper data will be populated in the variables, passing it on to the survey app for inclusion in each response. This is the magic that will help you pinpoint customers to interview down the road, so take special care to test that all is working before sending to all recipients. How you construct the survey link will vary depending on what survey tool and email service provider you use, so don’t take my example as gospel. You’ll need to read the documentation for your survey and email apps to set things up properly.
Pilot before sending
By now, you’ve whipped yourself into a fever pitch over your brilliant survey and the data you hope to collect. Your finger is on the send button, poised for action, but there’s one very important thing to do before you send to the entire list of customers: send a pilot email. How do you know if your questions are clear, your form logic is sound, and you’re passing variables from the email to the survey properly? You won’t, unless you send to a small segment of your recipients first.
The data collected in your pilot will make plain where your survey needs refinement. This data won’t be used in your final analysis, as you’re probably going to make a few changes to your questions.
Send the pilot survey to enough people that you can really stress test the clarity of the questions and data you’re gathering, while considering how much data can you comfortably throw out. If you’re sending your final survey to a few thousand people, you might find a couple of hundred recipients for your pilot will give you enough insight into what to improve while leaving the vast majority of the recipients for your final survey.
After you’ve sent your pilot, made your survey adjustments, and ensured the variables are being passed from your email into the survey app, you’re ready to send to the remainder of your customers. This is your moment of glory!
Analyzing your results
After a couple of weeks you can probably safely close the survey so no other responses come in as you transition from data gathering to data analysis. Any survey app worth its salt will chart responses to your multiple choice questions. Reviewing these charts is a great place to start your analysis. Is there anything particularly interesting that stands out? Jot down some of your observations. I like to print screenshots of the charts for each question, highlighting areas of interest. These prints become a particularly handy reference point for the next step in your analysis.
Printing results from a survey makes comparing different customers easy.
Viewing aggregate data about all responses is interesting, but the deltas between different types of customers are where the real revelations happen. Remember those filter questions you added to your survey? They’re the tool that’ll help you compare customer segments.
Most survey apps will let you filter the data based on response to a question. If the one you’re using doesn’t, you can always export your data and create pivot tables in Excel. Try filtering your data based on one of your filter questions, such as industry, company size, or devices used. Now compare those printed screenshots of baseline responses to the filtered data. Chances are you’ll see some significant differences in how each group responded to your questions, giving you clues about the variance in interests and motivations in customer segments and a leg up as you work on future design projects.
Open-ended responses are equally interesting, but much more time-consuming to analyze. Yes, you need to read through thousands of responses, some of which are constructive and some of which are not. Taking the time to tag each open response will help you see trends and filter out the responses that are unhelpful.
Unlike questions with predefined answers, open-ended responses let users express unique ideas and use cases you may not be looking for. The tedium of reading thousands of response is always cut by eureka moments when users tell you something fascinating that changes your perspective on your app. These are the folks you want to pull out for follow-up interviews. Because you’ve already captured their email addresses when you set up your survey and your email, getting in touch will be a piece of cake.
Filter, compare, interview, and summarize; then share your findings with your colleagues. Reports are great for head honchos, but if you want to really inform and inspire, create a video, a poster series, or even a comic to communicate what you’ve learned. Want to get really fancy? Store your survey results in a centrally accessible location so anyone in your company can research and discover the insights they need to make more informed designs.
Good design researchers discover valuable insights. Great design researchers turn those insights into stories.
Conclusion
As we enter the new year, it’s a great time to reflect on the work we’ve done in the past and how we can do better in the future. Without a doubt, designers working with a foundation of insights about customers can make more effective UIs. But designers aren’t the only ones who stand to gain from the data collected in an annual survey—anyone who makes things for or communicates with customers will find themselves empowered to do better work when they know more about the people they serve. The data you collect with your survey is a fantastic holiday gift to your colleagues, one that they’ll appreciate throughout the year. |

The Command Position Principle |
Living where I do, in a small village in rural North Wales, getting anywhere means driving along narrow country roads. Most of these are just about passable when two cars meet.
If you’re driving too close to the centre of the road, when two drivers meet you stop, glare at each other and no one goes anywhere. Drive too close to your nearside and in summer you’ll probably scratch your paintwork on the hedgerows, or in winter you’ll sink your wheels into mud.
Driving these lanes requires a balance between caring for your own vehicle and consideration for someone else’s, but all too often, I’ve seen drivers pushed towards the hedgerows and mud when someone who’s inconsiderate drives too wide because they don’t want to risk scratching their own paintwork or getting their wheels dirty.
If you learn to ride a motorcycle, you’ll be taught about the command position:
Approximate central position, or any position from which the rider can exert control over invitation space either side.
The command position helps motorcyclists stay safe, because when they ride in the centre of their lane it prevents other people, usually car drivers, from driving alongside, either forcing them into the curb or potentially dangerously close to oncoming traffic.
Taking the command position isn’t about motorcyclists being aggressive, it’s about them being confident. It’s them knowing their rightful place on the road and communicating that through how they ride.
I’ve recently been trying to take that command position when driving my car on our lanes. When I see someone coming in the opposite direction, instead of instinctively moving closer to my nearside — and in so doing subconsciously invite them into my space on the road — I hold both my nerve and a central position in my lane. Since I done this I’ve noticed that other drivers more often than not stay in their lane or pull closer to their nearside so we occupy equal space on the road. Although we both still need to watch our wing mirrors, neither of us gets our paint scratched or our wheels muddy.
We can apply this principle to business too, in particular to negotiations and the way we sell. Here’s how we might do that.
Commanding negotiations
When a customer’s been sold to well — more on that in just a moment — and they’ve made the decision to buy, the thing that usually stands in the way of us doing business is a negotiation over price. Some people treat negotiations as the equivalent of driving wide. They act offensively, because their aim is to force the other person into getting less, usually in return for giving more.
In encounters like this, it’s easy for us to act defensively. We might lack confidence in the price we ask for, or the value of the product or service we offer. We might compromise too early because of that. When that happens, there’s a pretty good chance that we’ll drive away with less than we deserve unless we use the command position principle to help us.
Before we start any negotiation it’s important to know that both sides ultimately want to reach an agreement. This isn’t always obvious. If one side isn’t already committed, at least in principle, then it’s not a negotiation at that point, it’s something else.
For example, a prospective customer may be looking to learn our lowest price so that they can compare it to our competitors. When that’s the case, we’ve probably failed to qualify that prospect properly as, after all, who wants to be chosen simply because they’re the cheapest? In this situation, negotiating is a waste of time since we don’t yet know that it will result in us making a deal. We should enter into a negotiation only when we know where we stand. So ask confidently: “Are you looking to [make a decision]?”
When that’s been confirmed, it’s down to everyone to compromise until a deal’s been reached. That’s because good negotiations aren’t about one side beating the other, they’re about achieving a good deal for both. Using the command position principle helps us to maintain control over our negotiating space and affords us the opportunity to give ground only if we need to and only when we’re ready. It can also ensure that the person we’re negotiating with gives up some of their space.
Commanding sales
It’s not always necessary to negotiate when we’re doing a business deal, but we should always be prepared to sell. One of the most important parts of our sales process should be controlling when and how we tell someone our price.
Unless it’s impossible to avoid, don’t work out a price for someone on the spot. When we do that we lose control over the time and place for presenting our price alongside the value factors that will contribute to the prospective customer accepting that price. For the same reason, never give a ballpark or, worse, a guesstimate figure. If the question of price comes up before we’re fully prepared, we should say politely that we need more time to work out a meaningful cost.
When we are ready, we shouldn’t email a price for our prospective customer to read unaccompanied. Instead, create an opportunity to talk a prospect through our figures, demonstrate how we arrived at them and, most importantly, explain the value of what we’re selling to their business. Agree a time and place to do this and, if possible, do it all face-to-face.
We shouldn’t hesitate when we give someone a price. When we sound even the slightest bit unsure or apologetic, we give the impression that we’ll be flexible in our position before negotiations have even begun.
Think about the command position principle, know the price and present it confidently. That way we send a clear signal that we know our business and how we deal with people. The command position principle isn’t about being cocky, it’s about showing other people respect, asking for it in return and showing it to ourselves.
Earlier, I mentioned selling well, because we sometimes hear people say that they dislike being sold to. In my experience, it’s not that people dislike the sales process, it’s that we dislike it done badly.
Taking part in a good sales process, either by selling or being sold to, can be a pleasurable experience. Try to be confident — after all, we understand how our skills will benefit a customer better than anyone else. Our confidence will inspire confidence in others.
Self-confidence isn’t the same as arrogance, just as the command position isn’t the same as riding without consideration for others. The command position principle preserves others’ space as well as our own. By the same token, we should be considerate of others’ time and not waste it and our own by attempting to force them into buying something that’s inappropriate.
To prevent this from happening, evaluate them well to ensure that they’re the right customer for us. If they’re not, let them go on their way. They’ll thank us for it and may well become customers the next time we meet.
The business of closing a deal can be made an enjoyable experience for everyone if we take control by guiding someone through the sales process by asking the right questions to uncover their concerns, then allaying them by being knowledgeable and confident. This is riding in the command position.
Just like demonstrating we know our rightful position on the road, knowing our rightful place in a business relationship and communicating that through how we deal with people will help everyone achieve an equitable balance. When that happens in business, as well as on the road, no one gets their paintwork scratched or their wheels muddy. |

Git for Grown-ups |
You are a clever and talented person. You create beautiful designs, or perhaps you have architected a system that even my cat could use. Your peers adore you. Your clients love you. But, until now, you haven’t *&^#^! been able to make Git work. It makes you angry inside that you have to ask your co-worker, again, for that *&^#^! command to upload your work.
It’s not you. It’s Git. Promise.
Yes, this is an article about the popular version control system, Git. But unlike just about every other article written about Git, I’m not going to give you the top five commands that you need to memorize; and I’m not going to tell you all your problems would be solved if only you were using this GUI wrapper or that particular workflow. You see, I’ve come to a grand realization: when we teach Git, we’re doing it wrong.
Let me back up for a second and tell you a little bit about the field of adult education. (Bear with me, it gets good and will leave you feeling both empowered and righteous.) Andragogy, unlike pedagogy, is a learner-driven educational experience. There are six main tenets to adult education:
Adults prefer to know why they are learning something.
The foundation of the learning activities should include experience.
Adults prefer to be able to plan and evaluate their own instruction.
Adults are more interested in learning things which directly impact their daily activities.
Adults prefer learning to be oriented not towards content, but towards problems.
Adults relate more to their own motivators than to external ones.
Nowhere in this list does it include “memorize the five most popular Git commands”. And yet this is how we teach version control: init, add, commit, branch, push. You’re an expert! Sound familiar? In the hierarchy of learning, memorizing commands is the lowest, or most basic, form of learning. At the peak of learning you are able to not just analyze and evaluate a problem space, but create your own understanding in relation to your existing body of knowledge.
“Fine,” I can hear you saying to yourself. “But I’m here to learn about version control.” Right you are! So how can we use this knowledge to master Git? First of all: I give you permission to use Git as a tool. A tool which you control and which you assign tasks to. A tool like a hammer, or a saw. Yes, your mastery of your tools will shape the kinds of interactions you have with your work, and your peers. But it’s yours to control. Git was written by kernel developers for kernel development. The web world has adopted Git, but it is not a tool designed for us and by us. It’s no Sass, y’know? Git wasn’t developed out of our frustration with managing CSS files in an increasingly complex ecosystem of components and atomic design. So, as you work through the next part of this article, give yourself a bit of a break. We’re in this together, and it’s going to be OK.
We’re going to do a little activity. We’re going to create your perfect Git cheatsheet.
I want you to start by writing down a list of all the people on your code team. This list may include:
developers
designers
project managers
clients
Next, I want you to write down a list of all the ways you interact with your team. Maybe you’re a solo developer and you do all the tasks. Maybe you only do a few things. But I want you to write down a list of all the tasks you’re actually responsible for. For example, my list looks like this:
writing code
reviewing code
publishing tested code to your server(s)
troubleshooting broken code
The next list will end up being a series of boxes in a diagram. But to start, I want you to write down a list of your tools and constraints. This list potentially has a lot of noun-like items and verb-like items:
code hosting system (Bitbucket? GitHub? Unfuddle? self-hosted?)
server ecosystem (dev/staging/live)
automated testing systems or review gates
automated build systems (that Jenkins dude people keep referring to)
Brilliant! Now you’ve got your actors and your actions, it’s time to shuffle them into a diagram. There are many popular workflow patterns. None are inherently right or wrong; rather, some are more or less appropriate for what you are trying to accomplish.
Centralized workflow
Everyone saves to a single place. This workflow may mean no version control, or a very rudimentary version control system which only ever has a single copy of the work available to the team at any point in time.
Branching workflow
Everyone works from a copy of the same place, merging their changes into the main copy as their work is completed. Think of the branches as a motorcycle sidecar: they’re along for the ride and probably cannot exist in isolation of the main project for long without serious danger coming to the either the driver or sidecar passenger. Branches are a fundamental concept in version control — they allow you to work on new features, bug fixes, and experimental changes within a single repository, but without forcing the changes onto others working from the same branch.
Forking workflow
Everyone works from their own, independent repository. A fork is an exact duplicate of a repository that a developer can make their own changes to. It can be kept up to date with additional changes made in other repositories, but it cannot force its changes onto another’s repository. A fork is a complete repository which can use its own workflow strategies. If developers wish to merge their work with the main project, they must make a request of some kind (submit a patch, or a pull request) which the project collaborators may choose to adopt or reject. This workflow is popular for open source projects as it enforces a review process.
Gitflow workflow
A specific workflow convention which includes five streams of parallel coding efforts: master, development, feature branches, release branches, and hot fixes. This workflow is often simplified down to a few elements by web teams, but may be used wholesale by software product teams. The original article describing this workflow was written by Vincent Driessen back in January 2010.
But these workflows aren’t about you yet, are they? So let’s make the connections.
From the list of people on your team you identified earlier, draw a little circle. Give each of these circles some eyes and a smile. Now I want you to draw arrows between each of these people in the direction that code (ideally) flows. Does your designer create responsive prototypes which are pushed to the developer? Draw an arrow to represent this.
Chances are high that you don’t just have people on your team, but you also have some kind of infrastructure. Hopefully you wrote about it earlier. For each of the servers and code repositories in your infrastructure, draw a square. Now, add to your diagram the relationships between the people and each of the machines in the infrastructure. Who can deploy code to the live server? How does it really get there? I bet it goes through some kind of code hosting system, such as GitHub. Draw in those arrows.
But wait!
The code that’s on your development machine isn’t the same as the live code. This is where we introduce the concept of a branch in version control. In Git, a repository contains all of the code (sort of). A branch is a fragment of the code that has been worked on in isolation to the other branches within a repository. Often branches will have elements in common. When we compare two (or more) branches, we are asking about the difference (or diff) between these two slivers. Often the master branch is used on production, and the development branch is used on our dev server. The difference between these two branches is the untested code that is not yet deployed.
On your diagram, see if you can colour-code according to the branch names at each of the locations within your infrastructure. You might find it useful to make a few different copies of the diagram to isolate each of the tasks you need to perform. For example: our team has a peer review process that each branch must go through before it is merged into the shared development branch.
Finally, we are ready to add the Git commands necessary to make sense of the arrows in our diagram. If we are bringing code to our own workstation we will issue one of the following commands: clone (the first time we bring code to our workstation) or pull. Remembering that a repository contains all branches, we will issue the command checkout to switch from one branch to another within our own workstation. If we want to share a particular branch with one of our team mates, we will push this branch back to the place we retrieved it from (the origin). Along each of the arrows in your diagram, write the name of the command you are are going to use when you perform that particular task.
From here, it’s up to you to be selfish. Before asking Git what command it would like you to use, sketch the diagram of what you want. Git is your tool, you are not Git’s tool. Draw the diagram. Communicate your tasks with your team as explicitly as you can. Insist on being a selfish adult learner — demand that others explain to you, in ways that are relevant to you, how to do the things you need to do today. |

URL Rewriting for the Fearful |
I think it was Marilyn Monroe who said, “If you can’t handle me at my worst, please just fix these rewrite rules, I’m getting an internal server error.” Even the blonde bombshell hated configuring URL rewrites on her website, and I think most of us know where she was coming from.
The majority of website projects I work on require some amount of URL rewriting, and I find it mildly enjoyable — I quite like a good rewrite rule. I suspect you may not share my glee, so in this article we’re going to go back to basics to try to make the whole rigmarole more understandable.
When we think about URL rewriting, usually that means adding some rules to an .htaccess file for an Apache web server. As that’s the most common case, that’s what I’ll be sticking to here. If you work with a different server, there’s often documentation specifically for translating from Apache’s mod_rewrite rules. I even found an automatic converter for nginx.
This isn’t going to be a comprehensive guide to every URL rewriting problem you might ever have. That would take us until Christmas. If you consider yourself a trial-and-error dabbler in the HTTP 500-infested waters of URL rewriting, then hopefully this will provide a little bit more of a basis to help you figure out what you’re doing. If you’ve ever found yourself staring at the white screen of death after screwing up your .htaccess file, don’t worry. As Michael Jackson once insipidly whined, you are not alone.
The basics
Rewrite rules form part of the Apache web server’s configuration for a website, and can be placed in a number of different locations as part of your virtual host configuration. By far the simplest and most portable option is to use an .htaccess file in your website root. Provided your server has mod_rewrite available, all you need to do to kick things off in your .htaccess file is:
RewriteEngine on
The general formula for a rewrite rule is:
RewriteRule URL/to/match URL/to/use/if/it/matches [options]
When we talk about URL rewriting, we’re normally talking about one of two things: redirecting the browser to a different URL; or rewriting the URL internally to use a particular file. We’ll look at those in turn.
Redirects
Redirects match an incoming URL, and then redirect the user’s browser to a different address. These can be useful for maintaining legacy URLs if content changes location as part of a site redesign. Redirecting the old URL to the new location makes sure that any incoming links, such as those from search engines, continue to work.
In 1998, Sir Tim Berners-Lee wrote that Cool URIs don’t change, encouraging us all to go the extra mile to make sure links keep working forever. I think that sometimes it’s fine to move things around — especially to correct bad URL design choices of the past — provided that you can do so while keeping those old URLs working. That’s where redirects can help.
A redirect might look like this
RewriteRule ^article/used/to/be/here.php$ /article/now/lives/here/ [R=301,L]
Rewriting
By default, web servers closely map page URLs to the files in your site. On receiving a request for http://example.com/about/history.html the server goes to the configured folder for the example.com website, and then goes into the about folder and returns the history.html file.
A rewrite rule changes that process by breaking the direct relationship between the URL and the file system. “When there’s a request for /about/history.html” a rewrite rule might say, “use the file /about_section.php instead.”
This opens up lots of possibilities for creative ways to map URLs to the files that know how to serve up the page. Most MVC frameworks will have a single rule to rewrite all page URLs to one single file. That file will be a script which kicks off the framework to figure out what to do to serve the page.
RewriteRule ^for/this/url/$ /use/this/file.php [L]
Matching patterns
By now you’ll have noted the weird ^ and $ characters wrapped around the URL we’re trying to match. That’s because what we’re actually using here is a pattern. Technically, it is what’s called a Perl Compatible Regular Expression (PCRE) or simply a regex or regexp. We’ll call it a pattern because we’re not animals.
What are these patterns? If I asked you to enter your credit card expiry date as MM/YY then chances are you’d wonder what I wanted your credit card details for, but you’d know that I wanted a two-digit month, a slash, and a two-digit year. That’s not a regular expression, but it’s the same idea: using some placeholder characters to define the pattern of the input you’re trying to match.
We’ve already met two regexp characters.
^
Matches the beginning of a string
$
Matches the end of a string
When a pattern starts with ^ and ends with $ it’s to make sure we match the complete URL start to finish, not just part of it. There are lots of other ways to match, too:
[0-9]
Matches a number, 0–9. [2-4] would match numbers 2 to 4 inclusive.
[a-z]
Matches lowercase letters a–z
[A-Z]
Matches uppercase letters A–Z
[a-z0-9]
Combining some of these, this matches letters a–z and numbers 0–9
These are what we call character groups. The square brackets basically tell the server to match from the selection of characters within them. You can put any specific characters you’re looking for within the brackets, as well as the ranges shown above.
However, all these just match one single character. [0-9] would match 8 but not 84 — to match 84 we’d need to use [0-9] twice.
[0-9][0-9]
So, if we wanted to match 1984 we could to do this:
[0-9][0-9][0-9][0-9]
…but that’s getting silly. Instead, we can do this:
[0-9]{4}
That means any character between 0 and 9, four times. If we wanted to match a number, but didn’t know how long it might be (for example, a database ID in the URL) we could use the + symbol, which means one or more.
[0-9]+
This now matches 1, 123 and 1234567.
Putting it into practice
Let’s say we need to write a rule to match article URLs for this website, and to rewrite them to use /article.php under the hood. The articles all have URLs like this:
2013/article-title/
They start with a year (from 2005 up to 2013, currently), a slash, and then have a URL-safe version of the article title (a slug), ending in a slash. We’d match it like this:
^[0-9]{4}/[a-z0-9-]+/$
If that looks frightening, don’t worry. Breaking it down, from the start of the URL (^) we’re looking for four numbers ([0-9]{4}). Then a slash — that’s just literal — and then anything lowercase a–z or 0–9 or a dash ([a-z0-9-]) one or more times (+), ending in a slash (/$).
Putting that into a rewrite rule, we end up with this:
RewriteRule ^[0-9]{4}/[a-z0-9-]+/$ /article.php
We’re getting close now. We can match the article URLs and rewrite them to use article.php. Now we just need to make sure that article.php knows which article it’s supposed to display.
Capturing groups, and replacements
When rewriting URLs you’ll often want to take important parts of the URL you’re matching and pass them along to the script that handles the request. That’s usually done by adding those parts of the URL on as query string arguments. For our example, we want to make sure that article.php knows the year and the article title we’re looking for. That means we need to call it like this:
/article.php?year=2013&slug=article-title
To do this, we need to mark which parts of the pattern we want to reuse in the destination. We do this with round brackets or parentheses. By placing parentheses around parts of the pattern we want to reuse, we create what’s called a capturing group. To capture an important part of the source URL to use in the destination, surround it in parentheses.
Our pattern now looks like this, with parentheses around the parts that match the year and slug, but ignoring the slashes:
^([0-9]{4})/([a-z0-9-]+)/$
To use the capturing groups in the destination URL, we use the dollar sign and the number of the group we want to use. So, the first capturing group is $1, the second is $2 and so on. (The $ is unrelated to the end-of-pattern $ we used before.)
RewriteRule ^([0-9]{4})/([a-z0-9-]+)/$ /article.php?year=$1&slug=$2
The value of the year capturing group gets used as $1 and the article title slug is $2. Had there been a third group, that would be $3 and so on. In regexp parlance, these are called back-references as they refer back to the pattern.
Options
Several brain-taxing minutes ago, I mentioned some options as the final part of a rewrite rule. There are lots of options (or flags) you can set to change how the rule is processed. The most useful (to my mind) are:
R=301
Perform an HTTP 301 redirect to send the user’s browser to the new URL. A status of 301 means a resource has moved permanently and so it’s a good way of both redirecting the user to the new URL, and letting search engines know to update their indexes.
L
Last. If this rule matches, don’t bother processing the following rules.
Options are set in square brackets at the end of the rule. You can set multiple options by separating them with commas:
RewriteRule ^([0-9]{4})/([a-z0-9-]+)/$ /article.php?year=$1&slug=$2 [L]
or
RewriteRule ^about/([a-z0-9-]+).jsp/$ /about/$1/ [R=301,L]
Common pitfalls
Once you’ve built up a few rewrite rules, things can start to go wrong. You may have been there: a rule which looks perfectly good is somehow not matching. One common reason for this is hidden behind that [L] flag.
L for Last is a useful option to tell the rewrite engine to stop once the rule has been matched. This is what it does — the remaining rules in the .htaccess file are then ignored. However, once a URL has been rewritten, the entire set of rules are then run again on the new URL. If the new URL matches any of the rules, that too will be rewritten and on it goes.
One way to avoid this problem is to keep your ‘real’ pages under a folder path that will never match one of your rules, or that you can exclude from the rewrite rules.
Useful snippets
I find myself reusing the same few rules over and over again, just with minor changes. Here are some useful examples to refer back to.
Excluding a directory
As mentioned above, if you’re rewriting lots of fancy URLs to a collection of real files it can be helpful to put those files in a folder and exclude it from rewrite rules. This helps solve the issue of rewrite rules reapplying to your newly rewritten URL. To exclude a directory, put a rule like this at the top of your file, before your other rules. Our files are in a folder called _source, the dash in the rule means do nothing, and the L flag means the following rules won’t be applied.
RewriteRule ^_source - [L]
This is also useful for excluding things like CMS folders from your website’s rewrite rules
RewriteRule ^perch - [L]
Adding or removing www from the domain
Some folk like to use a www and others don’t. Usually, it’s best to pick one and go with it, and redirect the one you don’t want. On this site, we don’t use www.24ways.org so we redirect those requests to 24ways.org.
This uses a RewriteCond which is like an if for a rewrite rule: “If this condition matches, then apply the following rule.” In this case, it’s if the HTTP HOST (or domain name, basically) matches this pattern, then redirect everything:
RewriteCond %{HTTP_HOST} ^www.24ways.org$ [NC]
RewriteRule ^(.*)$ http://24ways.org/$1 [R=301,L]
The [NC] flag means ‘no case’ — the match is case-insensitive. The dots in the domain are escaped with a backslash, as a dot is a regular expression character which means match anything, so we escape it because we literally mean a dot in this instance.
Removing file extensions
Sometimes all you need to do to tidy up a URL is strip off the technology-specific file extension, so that /about/history.php becomes /about/history. This is easily achieved with the help of some more rewrite conditions.
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME}.php -f
RewriteRule ^(.+)$ $1.php [L,QSA]
This says if the file being asked for isn’t a file (!-f) and if it isn’t a directory (!-d) and if the file name plus .php is an actual file (-f) then rewrite by adding .php on the end. The QSA flag means ‘query string append’: append the existing query string onto the rewritten URL.
It’s these sorts of more generic catch-all rules that you need to watch out for when your .htaccess gets rerun after a successful match. Without care they can easily rematch the newly rewritten URL.
Logging for when it all goes wrong
Although not possible within your .htaccess file, if you have access to your Apache configuration files you can enable rewrite logging. This can be useful to track down where a rule is going wrong, if it’s matching incorrectly or failing to match. It also gives you an overview of the amount of work being done by the rewrite engine, enabling you to rearrange your rules and maximise performance.
RewriteEngine On
RewriteLog "/full/system/path/to/rewrite.log"
RewriteLogLevel 5
To be doubly clear: this will not work from an .htaccess file — it needs to be added to the main Apache configuration files. (I sometimes work using MAMP PRO locally on my Mac, and this can be pasted into the snappily named Customized virtual host general settings box in the Advanced tab for your site.)
The white screen of death
One of the most frustrating things when working with rewrite rules is that when you make a mistake it can result in the server returning an HTTP 500 Internal Server Error. This in itself isn’t an error message, of course. It’s more of a notification that an error has occurred. The real error message can usually be found in your Apache error log.
If you have access to your server logs, check the Apache error log and you’ll usually find a much more descriptive error message, pointing you towards your mistake. (Again, if using MAMP PRO, go to Server, Apache and the View Log button.)
In conclusion
Rewriting URLs can be a bear, but the advantages are clear. Keeping a tidy URL structure, disconnected from the technology or file structure of your site can result in URLs that are easier to use and easier to maintain into the future.
If you’re redesigning a site, remember that cool URIs don’t change, so budget some time to make sure that any content you move has a rewrite rule associated with it to keep any links working.
Further reading
To find out more about URL rewriting and perhaps even learn more about regular expressions, I can recommend the following resources.
From the horse’s mouth, the Apache mod_rewrite documentation
Particularly useful with that documentation is the RewriteRule Flags listing
You may wish to don sunglasses to follow the otherwise comprehensive Regular-Expressions.info tutorial
Friend of 24 ways, Neil Crosby has a mod_rewrite Beginner’s Guide which I’ve found handy over the years.
As noted at the start, this isn’t a fully comprehensive guide, but I hope it’s useful in finding your feet with a powerful but sometimes annoying technology. Do you have useful snippets you often use on projects? Feel free to share them in the comments. |

Bringing Design and Research Closer Together |
The ‘should designers be able to code’ debate has raged for some time, but I’m interested in another debate: should designers be able to research?
Are you a designer who can do research? Good research and the insights you uncover inspire fresh ways of thinking and get your creative juices flowing. Good research brings clarity to a woolly brief. Audience insight helps sharpen your focus on what’s really important. Experimentation through research and design brings a sense of playfulness and curiosity to your work. Good research helps you do good design.
Being a web designer today is pretty tough, particularly if you’re a freelancer and work on your own. There are so many new ideas, approaches to workflow and trends and tools to keep up with. How do you decide which things to do and which to ignore? A modern web designer needs to be able to consider the needs of the audience, design appropriate IAs and layouts, choose colour palettes, pick appropriate typefaces and type layouts, wrangle with content, style, code, dabble in SEO, and the list goes on and on. Not only that, but today’s web designer also has to keep up with the latest talking points in the industry: responsive design, Agile, accessibility, Sass, Git, lean UX, content first, mobile first, blah blah blah. Any good web designer doesn’t need to be persuaded about the merits of including research in their toolkit, but do you really have time to include research too?
Who is responsible for research?
Generally, research in the web industry forms part of other disciplines and isn’t so much a discipline in its own right. It’s very often thought of as part of UX, or activities that make up a process such as IA or content strategy. Research is often undertaken by UX designers, information architects or content strategists and isn’t something designers or developers get that involved in. Some people lump all of these activities together and label it design research and have design researchers to do it. Some companies, such as the one I run with my husband Mark, are lucky enough to have someone with specialist research knowledge (yup, that would be me folks) who can lead all or most of the research work undertaken by the company. See also Mule Design, GOV.UK, the BBC, Mailchimp, Facebook and Twitter.
What if you’re not lucky enough to have your own researcher or team of researchers? Often research is the kind of thing that’s nice to have, or it can be cut from scope when doing the budget dance with a client. It often forms part of the discovery phase of a project and sometimes just becomes a tick-box exercise. But research isn’t just user testing and it shouldn’t just live in a report on Basecamp that no one reads. I would argue that research and experimentation is a way of working or an approach to how you design. Research can be used during the whole design process and must be a vital part of a designer’s workflow on every project. Even if you work in a small studio, you can still create a culture of audience insight. Even if you work on your own, you can still absorb yourself in as much audience data as you can throughout the project life cycle. Here’s how.
Research is everyone’s job
There is a subtle difference between writing a research report and delivering it to a client, and them actually using it and applying the insights to their thought process. In my experience of working in the audiences team at the BBC, research was most effective when the role was embedded in the production team and insights were used as part of the editorial process.
In this section I’ll talk through some common problems you might encounter in a typical project life cycle and show you ways you can use research to help you. For the sake of this article, let’s imagine that we’re talking about a particular project here and not ongoing product development. The same principles can of course be applied then, but even if you work in-house rather than on the agency side, you’re probably used to working on distinct projects or phases of work.
1. Problem: I want to come up with a new product idea.
Solution: Inspiration through insights.
Before you begin a new project, a good way of quickly absorbing all the existing knowledge that there maybe about a theme, product type or website is to literally surround yourself with it. This is especially relevant for new ideas or product development. Create an incident room if you can: fill the walls of your meeting room, the walls near your desk, or even just use a pinboard or online pinboard if space is tight or you’re working with a dispersed team. The same process can be used throughout a project’s or product life cycle — read about how MailChimp has applied this idea.
Let’s take a new product idea as an example. Say you wanted to develop a responsive tool for web designers but you weren’t sure what aspect of responsive design to focus on. First of all, you should pose a hypothesis or problem statement to gather ideas around. For example: “How to speed up a designer’s responsive workflow.” You would then need to gather insights around this topic. You could run some interviews with freelance designers about how they work responsively. You could shadow a development team for the day to understand their processes. You could observe conversations on Twitter or IRC or wherever your target audience interact to see what people talk about. You could search out industry data and articles currently available.
The next stage is to comb through this data and extract insights from it. You can use good old Post-it notes and a sharpie: capture one insight or thought per Post-it. If one insight leads into another, use two Post-its. The objective is volume. Try to ensure clarity in each Post-it so you don’t have to go back and reference material again (maybe you could use a key if you think it’ll get confusing).
After this, stick them all up and synthesise the same way you would for any kind of cluster or affinity sort. Organise into broad themes. These themes then become springboards for further exploration and idea generation. You might see a gap or opportunity in one particular area, both from a workflow perspective but also from a business perspective. Bingo. Your insights then become the fuel for ideas generation.
This method doesn’t just have to be used for new products — it works particularly well in a discovery phase for new projects or for new features in an existing product. We’re doing something similar for our own responsive tool, Gridset at the moment.

2. Problem: You’re starting a new project and need to know the basics before you get headlong into designing or building.
Solution: Quantitative survey.
Common questions might be:
Who are the users?
How many are there?
What are they like?
Why do they use the site?
What do they need from the site?
What are their goals?
Print out and stick up what you already know and have in your project space or ‘incident room’: any reports you have found or been given, analytics graphs, personas, pen portraits, as well as screengrabs of the current website, product or branding. Spend time looking through it all and identify the gaps.
If you have very little existing audience data, a quick and easy way to get some baseline information is to run a quick user survey on a current website. You can establish basic demographic information, appreciation and views of the website as it stands, as well as delve a little deeper into needs and wants. This is also vital if you want some kind of trackable measures to go back to once you have designed and built your shiny new website for your client — read more in my article for 24 ways last year.)
We use surveys a lot at Mark Boulton Design for our client work. Here’s a screen grab of one we ran in March on http://info.cern.ch before we redesigned the site and did the work on the First Website Project. We repeated the survey after the new website went live and were able to compare the results. Both surveys were a great source of insight to the project team as well as for the project stakeholders who needed to pitch the idea of the hack days and fundraise for them.
Once you’ve run your survey, you should always write up a short summary for yourself and your client to refer to. If you’re not a trained researcher, you should try to read up on analysis techniques or data visualisation. It can be easy to misinterpret data and make it bend to the story you are trying to tell. You should be looking for the story in the data and present it without bias.
If you’re using the ‘incident room’ method I mentioned earlier on, you can also extract the insights onto post it notes and add them to your growing body of knowledge.

3. Problem: You have a prototype of a new design and you need some feedback from real users.
Solution: User interviews and task based testing.
Interviewing is a staple research method that every designer should master as it can be used throughout a project life cycle. Erika Hall recently wrote a great article on the basics for A List Apart. From stakeholder interviews in a discovery phase, to initial user research, right through to task based testing and iteration, interviews can be enormously helpful. They are very time-consuming, however, and although speaking to someone is better than speaking to no one, it’s always better to plan to do a few interviews at once, rather than one or two. I generally find that patterns only start to emerge after I’ve spoken to 4 or 5 people. Interviews are another thing we do a lot of at Mark Boulton Design. Most of the interviews we do are remote due to the location of our clients and their users.
Rigour is an important consideration in all research activities and especially if you’re a non-researcher. Interviews particularly can be easily skewed by an inexperienced facilitator, which is why pairing can be a good approach. Building rapport, questioning, time keeping, note taking and thinking on your feet can be difficult to do all at once, so having a colleague take notes while you concentrate on leading the conversation can work really well. It’s important for the note taker to sit in on more than one interview so that they get a more rounded view of the feedback. The same person should also be involved in the analysis of the data.
Interviews can be analysed and written up in a report or summary as with other types of research. I often use the same kind of collaborative process detailed earlier for deciding on themes, particularly if multiple members of the team have been involved in interviewing.
Interviews are particularly useful for our incident room and can provide much colour and insight to an exploratory process. I often find verbatim quotes to be the most insightful type of data. You might find that an inexperienced researcher (or designer who is used to solving problems) will jump to interpretation too soon and forget to just listen to what the interviewee is saying. Capturing the exact form of words a person uses can help get away from this.

4. Problem: How successful have I been with this new design?
Solution: Key performance indicators
Once your new design has been realised, it’s important to evaluate it. What works, what doesn’t work so well? As well as a straightforward design crit, don’t forget to introduce audience insights into a review meeting or project wash up.
Work out what your KPIs — your key performance indicators — will be beforehand and then you can start to track them over time. For example, number of visits, appreciation of the site, willingness to recommend the site to a friend, number of sales, and number of conversions are all sensible measures to track. Interviews can again be helpful but cold, hard numbers are often better here. Read Corey Vilhauer’s take on this on A List Apart.
Consistency is key here. If you have looked at your analytics and done a survey beforehand, you will have a baseline to start from. Don’t keep changing your measures and questions, or your data will not be comparable. Pick a few key questions or a set of measures, create a survey and then run it once a month, once a quarter, every six months or annually. You’ll start to see changes over time as the design beds in. You may see seasonal trends and spot patterns in the data related to other activities like marketing, promotion and so on. Keeping a record of all of this will increase your understanding of your audience. We’ve created a satisfaction survey for Gridset with a number of measures that we track on an ongoing basis. MailChimp has also created an annual survey with the aim of tracking their audience measures over time

Anyone can do research
Research can be brought into the project life cycle at any stage. And of course, anyone can do research — you don’t need to be a researcher. Some of the main skills most designers possess are also key research skills: inquisitive nature, problem solving, playfulness, empathy, and so on.
We have a small team at Mark Boulton Design. Most of the team are designers and the rest of us focus on supporting the team and clients both in terms of billable work (research, content strategy, project management) as well as the non-billable things like finance and studio management.
Despite my best intentions, in the past I’ve undertaken research for clients in isolation — first being briefed by the design lead, carrying out the research and then delivering the findings back, trusting the design team to take the findings on board. This was often due to time and availability of resources.
We’ve been trying hard to join up our processes and collaborate even more across the team. Undertaking heuristic or design reviews collaboratively; taking part in frequent critiques of our work and the work of others together; pairing a researcher and a designer to run interviews; workshopping results from interviews to come up with recommendations; working closely together on questionnaire design; shadowing each other on tasks that don’t fall within our core skills. A little thing like moving our desks around has also helped us have more conversations that we can all be a part of.
I’ve come to the conclusion that my role as the research director at Mark Boulton Design is actually a facilitator of research. As well as carrying out research, I am responsible for ensuring that research happens consistently across the team. I am responsible for empowering and training our designers so they feel confident in carrying out their own user, audience or design research for clients. So they know what to look for, when to listen, when to probe and when to take note of something. So they know how to look for themes, how to synthesise insights from research and how to apply them to their work.
Better research leads to better design
So, are you a designer who can do research? Are you a researcher who can design? The best designers are a lucky combination of researcher and designer. If you’re not one of those, look at ways of enhancing the skills you lack. Because there’s no doubt in my mind, that becoming a better researcher will make you a better designer.

Grunt for People Who Think Things Like Grunt are Weird and Hard |
Front-end developers are often told to do certain things:
Work in as small chunks of CSS and JavaScript as makes sense to you, then concatenate them together for the production website.
Compress your CSS and minify your JavaScript to make their file sizes as small as possible for your production website.
Optimize your images to reduce their file size without affecting quality.
Use Sass for CSS authoring because of all the useful abstraction it allows.
That’s not a comprehensive list of course, but those are the kind of things we need to do. You might call them tasks.
I bet you’ve heard of Grunt. Well, Grunt is a task runner. Grunt can do all of those things for you. Once you’ve got it set up, which isn’t particularly difficult, those things can happen automatically without you having to think about them again.
But let’s face it: Grunt is one of those fancy newfangled things that all the cool kids seem to be using but at first glance feels strange and intimidating. I hear you. This article is for you.
Let’s nip some misconceptions in the bud right away
Perhaps you’ve heard of Grunt, but haven’t done anything with it. I’m sure that applies to many of you. Maybe one of the following hang-ups applies to you.
I don’t need the things Grunt does
You probably do, actually. Check out that list up top. Those things aren’t nice-to-haves. They are pretty vital parts of website development these days. If you already do all of them, that’s awesome. Perhaps you use a variety of different tools to accomplish them. Grunt can help bring them under one roof, so to speak. If you don’t already do all of them, you probably should and Grunt can help. Then, once you are doing those, you can keep using Grunt to do more for you, which will basically make you better at doing your job.
Grunt runs on Node.js — I don’t know Node
You don’t have to know Node. Just like you don’t have to know Ruby to use Sass. Or PHP to use WordPress. Or C++ to use Microsoft Word.
I have other ways to do the things Grunt could do for me
Are they all organized in one place, configured to run automatically when needed, and shared among every single person working on that project? Unlikely, I’d venture.
Grunt is a command line tool — I’m just a designer
I’m a designer too. I prefer native apps with graphical interfaces when I can get them. But I don’t think that’s going to happen with Grunt1.
The extent to which you need to use the command line is:
Navigate to your project’s directory.
Type grunt and press Return.
After set-up, that is, which again isn’t particularly difficult.
OK. Let’s get Grunt installed
Node is indeed a prerequisite for Grunt. If you don’t have Node installed, don’t worry, it’s very easy. You literally download an installer and run it. Click the big Install button on the Node website.
You install Grunt on a per-project basis. Go to your project’s folder. It needs a file there named package.json at the root level. You can just create one and put it there.
package.json at root
The contents of that file should be this:
{
"name": "example-project",
"version": "0.1.0",
"devDependencies": {
"grunt": "~0.4.1"
}
}
Feel free to change the name of the project and the version, but the devDependencies thing needs to be in there just like that.
This is how Node does dependencies. Node has a package manager called NPM (Node packaged modules) for managing Node dependencies (like a gem for Ruby if you’re familiar with that). You could even think of it a bit like a plug-in for WordPress.
Once that package.json file is in place, go to the terminal and navigate to your folder. Terminal rubes like me do it like this:
Terminal rube changing directories
Then run the command:
npm install
After you’ve run that command, a new folder called node_modules will show up in your project.
Example of node_modules folder
The other files you see there, README.md and LICENSE are there because I’m going to put this project on GitHub and that’s just standard fare there.
The last installation step is to install the Grunt CLI (command line interface). That’s what makes the grunt command in the terminal work. Without it, typing grunt will net you a “Command Not Found”-style error. It is a separate installation for efficiency reasons. Otherwise, if you had ten projects you’d have ten copies of Grunt CLI.
This is a one-liner again. Just run this command in the terminal:
npm install -g grunt-cli
You should close and reopen the terminal as well. That’s a generic good practice to make sure things are working right. Kinda like restarting your computer after you install a new application was in the olden days.
Let’s make Grunt concatenate some files
Perhaps in our project there are three separate JavaScript files:
jquery.js – The library we are using.
carousel.js – A jQuery plug-in we are using.
global.js – Our authored JavaScript file where we configure and call the plug-in.
In production, we would concatenate all those files together for performance reasons (one request is better than three). We need to tell Grunt to do this for us.
But wait. Grunt actually doesn’t do anything all by itself. Remember Grunt is a task runner. The tasks themselves we will need to add. We actually haven’t set up Grunt to do anything yet, so let’s do that.
The official Grunt plug-in for concatenating files is grunt-contrib-concat. You can read about it on GitHub if you want, but all you have to do to use it on your project is to run this command from the terminal (it will henceforth go without saying that you need to run the given commands from your project’s root folder):
npm install grunt-contrib-concat --save-dev
A neat thing about doing it this way: your package.json file will automatically be updated to include this new dependency. Open it up and check it out. You’ll see a new line:
"grunt-contrib-concat": "~0.3.0"
Now we’re ready to use it. To use it we need to start configuring Grunt and telling it what to do.
You tell Grunt what to do via a configuration file named Gruntfile.js2
Just like our package.json file, our Gruntfile.js has a very special format that must be just right. I wouldn’t worry about what every word of this means. Just check out the format:
module.exports = function(grunt) {
// 1. All configuration goes here
grunt.initConfig({
pkg: grunt.file.readJSON('package.json'),
concat: {
// 2. Configuration for concatinating files goes here.
}
});
// 3. Where we tell Grunt we plan to use this plug-in.
grunt.loadNpmTasks('grunt-contrib-concat');
// 4. Where we tell Grunt what to do when we type "grunt" into the terminal.
grunt.registerTask('default', ['concat']);
};
Now we need to create that configuration. The documentation can be overwhelming. Let’s focus just on the very simple usage example.
Remember, we have three JavaScript files we’re trying to concatenate. We’ll list file paths to them under src in an array of file paths (as quoted strings) and then we’ll list a destination file as dest. The destination file doesn’t have to exist yet. It will be created when this task runs and squishes all the files together.
Both our jquery.js and carousel.js files are libraries. We most likely won’t be touching them. So, for organization, we’ll keep them in a /js/libs/ folder. Our global.js file is where we write our own code, so that will be right in the /js/ folder. Now let’s tell Grunt to find all those files and squish them together into a single file named production.js, named that way to indicate it is for use on our real live website.
concat: {
dist: {
src: [
'js/libs/*.js', // All JS in the libs folder
'js/global.js' // This specific file
],
dest: 'js/build/production.js',
}
}
Note: throughout this article there will be little chunks of configuration code like above. The intention is to focus in on the important bits, but it can be confusing at first to see how a particular chunk fits into the larger file. If you ever get confused and need more context, refer to the complete file.
With that concat configuration in place, head over to the terminal, run the command:
grunt
and watch it happen! production.js will be created and will be a perfect concatenation of our three files. This was a big aha! moment for me. Feel the power course through your veins. Let’s do more things!
Let’s make Grunt minify that JavaScript
We have so much prep work done now, adding new tasks for Grunt to run is relatively easy. We just need to:
Find a Grunt plug-in to do what we want
Learn the configuration style of that plug-in
Write that configuration to work with our project
The official plug-in for minifying code is grunt-contrib-uglify. Just like we did last time, we just run an NPM command to install it:
npm install grunt-contrib-uglify --save-dev
Then we alter our Gruntfile.js to load the plug-in:
grunt.loadNpmTasks('grunt-contrib-uglify');
Then we configure it:
uglify: {
build: {
src: 'js/build/production.js',
dest: 'js/build/production.min.js'
}
}
Let’s update that default task to also run minification:
grunt.registerTask('default', ['concat', 'uglify']);
Super-similar to the concatenation set-up, right?
Run grunt at the terminal and you’ll get some deliciously minified JavaScript:
Minified JavaScript
That production.min.js file is what we would load up for use in our index.html file.
Let’s make Grunt optimize our images
We’ve got this down pat now. Let’s just go through the motions. The official image minification plug-in for Grunt is grunt-contrib-imagemin. Install it:
npm install grunt-contrib-imagemin --save-dev
Register it in the Gruntfile.js:
grunt.loadNpmTasks('grunt-contrib-imagemin');
Configure it:
imagemin: {
dynamic: {
files: [{
expand: true,
cwd: 'images/',
src: ['**/*.{png,jpg,gif}'],
dest: 'images/build/'
}]
}
}
Make sure it runs:
grunt.registerTask('default', ['concat', 'uglify', 'imagemin']);
Run grunt and watch that gorgeous squishification happen:
Squished images
Gotta love performance increases for nearly zero effort.
Let’s get a little bit smarter and automate
What we’ve done so far is awesome and incredibly useful. But there are a couple of things we can get smarter on and make things easier on ourselves, as well as Grunt:
Run these tasks automatically when they should
Run only the tasks needed at the time
For instance:
Concatenate and minify JavaScript when JavaScript changes
Optimize images when a new image is added or an existing one changes
We can do this by watching files. We can tell Grunt to keep an eye out for changes to specific places and, when changes happen in those places, run specific tasks. Watching happens through the official grunt-contrib-watch plugin.
I’ll let you install it. It is exactly the same process as the last few plug-ins we installed. We configure it by giving watch specific files (or folders, or both) to watch. By watch, I mean monitor for file changes, file deletions or file additions. Then we tell it what tasks we want to run when it detects a change.
We want to run our concatenation and minification when anything in the /js/ folder changes. When it does, we should run the JavaScript-related tasks. And when things happen elsewhere, we should not run the JavaScript-related tasks, because that would be irrelevant. So:
watch: {
scripts: {
files: ['js/*.js'],
tasks: ['concat', 'uglify'],
options: {
spawn: false,
},
}
}
Feels pretty comfortable at this point, hey? The only weird bit there is the spawn thing. And you know what? I don’t even really know what that does. From what I understand from the documentation it is the smart default. That’s real-world development. Just leave it alone if it’s working and if it’s not, learn more.
Note: Isn’t it frustrating when something that looks so easy in a tutorial doesn’t seem to work for you? If you can’t get Grunt to run after making a change, it’s very likely to be a syntax error in your Gruntfile.js. That might look like this in the terminal:
Errors running Grunt
Usually Grunt is pretty good about letting you know what happened, so be sure to read the error message. In this case, a syntax error in the form of a missing comma foiled me. Adding the comma allowed it to run.
Let’s make Grunt do our preprocessing
The last thing on our list from the top of the article is using Sass — yet another task Grunt is well-suited to run for us. But wait? Isn’t Sass technically in Ruby? Indeed it is. There is a version of Sass that will run in Node and thus not add an additional dependency to our project, but it’s not quite up-to-snuff with the main Ruby project. So, we’ll use the official grunt-contrib-sass plug-in which just assumes you have Sass installed on your machine. If you don’t, follow the command line instructions.
What’s neat about Sass is that it can do concatenation and minification all by itself. So for our little project we can just have it compile our main global.scss file:
sass: {
dist: {
options: {
style: 'compressed'
},
files: {
'css/build/global.css': 'css/global.scss'
}
}
}
We wouldn’t want to manually run this task. We already have the watch plug-in installed, so let’s use it! Within the watch configuration, we’ll add another subtask:
css: {
files: ['css/*.scss'],
tasks: ['sass'],
options: {
spawn: false,
}
}
That’ll do it. Now, every time we change any of our Sass files, the CSS will automaticaly be updated.
Let’s take this one step further (it’s absolutely worth it) and add LiveReload. With LiveReload, you won’t have to go back to your browser and refresh the page. Page refreshes happen automatically and in the case of CSS, new styles are injected without a page refresh (handy for heavily state-based websites).
It’s very easy to set up, since the LiveReload ability is built into the watch plug-in. We just need to:
Install the browser plug-in
Add to the top of the watch configuration:
. watch: {
options: {
livereload: true,
},
scripts: {
/* etc */
Restart the browser and click the LiveReload icon to activate it.
Update some Sass and watch it change the page automatically.
Live reloading browser
Yum.

If you’re the type that likes to learn by watching, I’ve made a screencast to accompany this article that I’ve published over on CSS-Tricks: First Moments with Grunt
Leveling up
As you might imagine, there is a lot of leveling up you can do with your build process. It surely could be a full time job in some organizations.
Some hardcore devops nerds might scoff at the simplistic setup we have going here. But I’d advise them to slow their roll. Even what we have done so far is tremendously valuable. And don’t forget this is all free and open source, which is amazing.
You might level up by adding more useful tasks:
Running your CSS through Autoprefixer (A+ Would recommend) instead of a preprocessor add-ons.
Writing and running JavaScript unit tests (example: Jasmine).
Build your image sprites and SVG icons automatically (example: Grunticon).
Start a server, so you can link to assets with proper file paths and use services that require a real URL like TypeKit and such, as well as remove the need for other tools that do this, like MAMP.
Check for code problems with HTML-Inspector, CSS Lint, or JS Hint.
Have new CSS be automatically injected into the browser when it ever changes.
Help you commit or push to a version control repository like GitHub.
Add version numbers to your assets (cache busting).
Help you deploy to a staging or production environment (example: DPLOY).
You might level up by simply understanding more about Grunt itself:
Read Grunt Boilerplate by Mark McDonnell.
Read Grunt Tips and Tricks by Nicolas Bevacqua.
Organize your Gruntfile.js by splitting it up into smaller files.
Check out other people’s and projects’ Gruntfile.js.
Learn more about Grunt by digging into its source and learning about its API.
Let’s share
I think some group sharing would be a nice way to wrap this up. If you are installing Grunt for the first time (or remember doing that), be especially mindful of little frustrating things you experience(d) but work(ed) through. Those are the things we should share in the comments here. That way we have this safe place and useful resource for working through those confusing moments without the embarrassment. We’re all in this thing together!
1 Maybe someday someone will make a beautiful Grunt app for your operating system of choice. But I’m not sure that day will come. The configuration of the plug-ins is the important part of using Grunt. Each plug-in is a bit different, depending on what it does. That means a uniquely considered UI for every single plug-in, which is a long shot.
Perhaps a decent middleground is this Grunt DevTools Chrome add-on.
2 Gruntfile.js is often referred to as Gruntfile in documentation and examples. Don’t literally name it Gruntfile — it won’t work. |

In Their Own Write: Web Books and their Authors |
The currency of written communication — words on the page, words on the screen — comprises many denominations. To further our ends in web design and development, we freely spend and receive several: tweets aphoristic and trenchant, banal and perfunctory; blog posts and articles that call us to action or reflection; anecdotes, asides, comments, essays, guides, how-tos, manuals, musings, notes, opinions, stories, thoughts, tips pro and not-so-pro. So many, many words.
Our industry (so much more than this, but what on earth are we, collectively?), our community thrives on writing and sharing knowledge and experience. 24 ways is a case in point. Everyone can learn and contribute through reading and writing — it’s what we’ve always done.
To web authors and readers seeking greater returns, though, broader culture has vouchsafed an enduring and singular artefact: the book.
Last month I asked a small sample of web book authors if they would be prepared to answer a few questions; most of them kindly agreed. In spirit, the survey was informal: I had neither hypothesis nor unground axe. I work closely with writers — and yes, I’ve edited or copy-edited books by several of the authors I surveyed — and wanted to share their thoughts about what it was like to write a book (“…it was challenging to find a coherent narrative”), why they did it (“Who wouldn’t want to?”) and what they learned from the experience (“That I could!”).
Reasons for writing a book
In web development the connection between authors and readers is unusually close and immediate. Working in our medium precipitates a unity that’s rare elsewhere. Yet writing and publishing a book, even during the current books revolution, is something only a few of us attempt and it remains daunting and a little remote. What spurs an author to try it? For some, it’s a deeply held resistance to prevailing trends:
I felt that designers and developers needed to be shaken out of what seemed to me had been years of stagnation.
—Andrew Clarke
Or even a desire to protect us from ourselves:
I felt that without a book that clearly defined progressive enhancement in a very approachable and succinct fashion, the web was at risk. I was seeing Tim Berners-Lee’s vision of universal availability slip away…
—Aaron Gustafson
Sometimes, there’s a knowledge gap to be filled by an author with the requisite excitement and need to communicate. Jon Hicks took his “pet subject” and was “enthused enough to want to spend all that time writing”, particularly because:
…there was a gap in the market for it. No one had done it before, and it’s still on its own out there, with no competition. It felt like I was able to contribute something.
Cennydd Bowles felt a professional itch at a particular point in his career, understanding that
[a]s a designer becomes more senior, they start looking for ways to scale the effects of their work. For some, that leads into management. For others, into writing.
Often, though, it’s also simply a personal challenge and ambition to explore a subject at length and create something substantial. Anna Debenham describes a motivation shared by several authors:
To be able to point to something more tangible than an article and be able to say “I did that.”
That sense of a book’s significance, its heft and gravity even, stems partly from the cultural esteem which honours books and their authors. Books have a long history as sources of wisdom, truth and power. Even with more books being published each year than ever before, writing one is still commonly considered a laudable achievement, including in our field.
Challenges of writing a book
Received wisdom has it that writing online should be brief and chunky and approachable: get to the point; divide it all up; subheadings and lists are our friends; write like you’re talking; no one has time to read. Much of such advice is true. Followed well, it lends our writing punch and pith, vigour and vim. The web is nimble, the web keeps up, and it suits what we write about developing for it. It’s perfect for delivering our observations, queries and investigations into all the various aspects of the work, professional and personal.
Yet even for digital natives like web authors, books printed and electronic retain an attractive glister.
Ideas can be developed more fully, their consequences explored to greater depth and extended with more varied examples, and the whole conveyed with more eloquence, more style. Why shouldn’t authors delay their conclusions if the intervening text is apposite, rich with value and helps to flesh out the skeleton of an argument? Conclusions might or might not be reached, of course, but a writer is at greater liberty in a book to digress in tangential and interesting ways.
Writing a book involves committing time, energy, thought and money. As Brian Suda found, it can be tough “getting the ideas out of my head into a cohesive blob of text.” Some authors end up talking to themselves…
It helps me to keep a real person in mind, someone who I’m talking to as I write. Sometimes I have the same conversations over and over in my head.
—Andrew Clarke
…while others are thinking ahead, concerned with how their book will be received:
Would anyone want to read it? Would they care? Would it be respected by my peers?
—Joe Leech
Challenges that arose time and again included “starting” and “getting words on the page” as well as “knowing when to stop” or “letting go”. Personal organization problems and those caused by publishers were also widely mentioned. Time loomed large. Making time, finding time. Giving up “sleep and some sanity” and realizing “it will take you far, far, far longer than you naively assumed”. Importantly, writing time is time away from gainful employment: Aaron Gustafson found the hardest thing about writing a book to be “the loss of income while I was writing.”
Perils and pleasures of editing
Editing, be it structural, technical or copy editing, is founded on reciprocity. Without openness and a shared belief that the book is worthwhile, work can founder in acrimony and mistrust. Editors are a book’s first and most critical (in every sense) readers. Effective and perceptive editing makes a book as good as it can be, finding the book within the draft like sculpture reveals the statue in the stone.
A good editor calls you out on poor assumptions and challenges you to really clarify your thinking. Whilst it can be difficult during the process to have your thinking challenged, it’s always been worth it — for me personally — in the long run. A good editor also reins you in when you’ve perhaps wandered off track or taken a little too long to make a point.
—Christopher Murphy
Andy Croll found editing “all positive” and Aaron Gustafson loves “working with a strong editor […] I want someone to tell it to me straight.” But it can be a rollercoaster, “both terrifying and the real moment of elation”. Mixed emotions during the editing process are common:
It was very uncomfortable! I knew it was making the work stronger, but it was awkward having my inconsistencies and waffle picked apart.
—Jon Hicks
It can be distressing to have written work looked over by a professional, particularly for first-time book authors whose expertise lies elsewhere:
I was a little nervous because I don’t consider myself a skilled writer — I never dreamed of becoming an author. I’m a designer, after all.
—Geri Coady
Communication is key, particularly when it comes to checking or changing the author’s words.
I like a good banter between me and the tech editor — if we can have a proper argument in Word comments, that’s great.
—Rachel Andrew
But if handled poorly, small battles can break out. Rachel Andrew again:
However, having had plenty of times where the technical editor has done nothing more than give a cursory glance, I started to leave little issues in for them to spot. If they picked them up I knew they were actually testing the code and I could be sure the work was being properly tech edited. If they didn’t spot them, I’d find someone myself to read through and check it!
A major concern for writers is that their voices will be altered, filtered, mangled or otherwise obscured by the editing process. Good copy editing must remain unnoticed while enhancing the author’s voice in print. Donna Spencer appreciated the way her editor “tidied up my work and made it a million times better, but left it sounding exactly like me.” Similarly, Andrew Travers “was incredibly impressed at how well my editor tightened up my own writing without it feeling like another’s voice” and Val Head sums up the consensus that:
the editor was able to help me express what I was trying to say in a better way […] I want to have editors for everything now.
At the keyboard, keep your friends close, but your editors closer.
Publishing and publishers
Conditions ought to militate against the allure of writing a book about web design and development. More books are published each year than ever before, so readerships elude new authors and readers can struggle to find authors to trust in their fields of interest. New spaces for more expansive online writing about working on and with the web are opening up (sites like Contents Magazine and STET), and seminal online web development texts are emerging. Publishing online is simple, far-reaching and immediate.
Much more so than articles and blog posts, books take time to research, write and read; add the complexity of commissioning, editing, designing, proofreading, printing, marketing and distribution processes, and it can take many months, even years to publish. The ceaseless headlong momentum of the web can leave articles more than a few weeks old whimpering in its wake, but updating them at least is straightforward; printed books about web development can depreciate as rapidly as the technology and techniques they describe, while retaining the “terrifying permanence that print bestows: your opinions will follow you forever”.
So much moves on, and becomes out of date. Companies featured get bought by larger companies and die, techniques improve and solutions featured become terribly out of date. Unlike a website, which could be updated continuously, a book represents the thinking ‘at that time’.
—Jon Hicks
Publishers work hard to mitigate these issues, promoting new books and new authors, bringing authors and readers together under a trusted banner. When a publisher packages up and releases a writer’s words, it confers a seal of approval and “badge of quality”, very important to new authors.
Publishers have other benefits to offer, from expert knowledge:
My publisher was extraordinarily supportive (and patient). Her expertise in my chosen subject was both a pressure (I didn’t want to let her down) and a reassurance (if she liked it, I knew it was going to be fine).
—Andrew Travers
…to systems and support mechanisms set up specifically to encourage writers and publish books:
Working as a team means you’re bringing in everyone’s expertise.
—Chui Chui Tan
As a writer, the best part about writing for a publisher was the writing infrastructure offered.
—Christopher Murphy
There can be drawbacks, however, and the occasional horror story:
We were just one small package on a huge conveyor belt. The publisher’s process ruled all.
—Cennydd Bowles
It’s only looking back I realise how poorly some publishers treat writers — especially when the work is so poorly remunerated.My worst experience was when a publisher decided, after I had completed the book, that they wanted to push a different take on the subject than the brief I had been given. Instead of talking to me, they rewrote chunks of my words, turning my advice into something that I would never have encouraged. Ultimately, I refused to let the book go out under my name alone, and I also didn’t really promote the book as I would have had to point out the things I did not agree with that had been inserted!
—Rachel Andrew
Self-publishing is now a realistic option for web authors, and can offers “complete control over the end product” as well as the possibility of earning more than a “pathetic author revenue percentage”. There can be substantial barriers, of course, as self-publishing authors must face for themselves the risks and challenges conventional publishers usually bear. Ideally, creating a book is a collaboration between author and publisher. Geri Coady found that “working with my publisher felt more like working with a partner or co-worker, rather than working for a boss.”
Wise words
So, after meeting the personal costs of writing and publishing a web book — fear, uncertainty, doubt, typing (so much typing) — and then smelling the roses of success, what’s left for an author to say? Some words, perhaps, to people thinking of writing a book.
Donna Spencer identifies a stumbling block common to many writers with an insight into the writing process:
Having talked to a lot of potential authors, I think most have the problem that they haven’t actually figured out the ‘answer’ to their premise yet. They feel like they are stuck in the writing, but they are actually stuck in the thinking.
For some no-nonsense, straightforward advice to cut through any anxiety or inadequacy, Rachel Andrew encourages authors to “treat it like any other work. There is no mystery to writing, you just have to write. Schedule the time, sit down, write words.” Tim Brown notes the importance of the editing process to refine a book and help authors reach their readers:
Hire good editors. Editors are amazing thinkers who can vastly improve the quality and clarity of a piece of writing.
We are too much beholden to the practical demands and challenges of technology, so Aaron Gustafson suggests a writer should “favor philosophies over techniques and your book will have a longer shelf life.”
Most intimations of renown and recognition are nipped in the bud by Joe Leech’s warning: “Don’t expect fame and fortune.” Although Cennydd Bowles’ bitter experience can be discouraging:
The sacrifices required are immense. You probably won’t make it.
…he would do things differently for a future book:
I would approach the book with […] far more concern about conveying the damn joy of what I do for a living.
The pleasure of writing, not just having written is captured by James Chudley when he recalls:
How much I enjoy writing and also how much I enjoy the discipline or having a side project like this. It’s a really good supplement to working life.
And Jon Hicks has words that any author will find comforting:
It will be fine. Everything will be fine. Just get on with it!
As the web expands effortlessly and ceaselessly to make room for all our words, yet it can also discourage the accumulation of any particular theme in one space, dividing rich seams and scattering knowledge across the web’s surface and into its deepest reaches. How many words become weightless and insubstantial, signals lost in the constant white noise of indistinguishable voices, unloved, unlinked? The web forgets constantly, despite the (somewhat empty) promise of digital preservation: articles and data are sacrificed to expediency, profit and apathy; online attention, acknowledgement and interest wax and wane in days, hours even.
Books can encourage deeper engagement in readers, and foster faith in an author, particularly if released under the imprint of a recognized publisher within the field. And books are changing. Although still not widely adopted, EPUB3 is the new standard in ebooks, bringing with it new possibilities for interaction and connection: readers with the text; readers with readers; and readers with authors. EPUB3 is built on HTML, CSS and JavaScript — sound familiar? In the past, we took what we could from the printed page to make the web; now books are rubbing up against what we’ve made.
So: a book.
Ever thought you could write one? Should write one? Would?
I’d like to thank all the authors who wrote their books and answered my questions.

Make Your Browser Dance |
It was a crisp winter’s evening when I pulled up alongside the pier. I stepped out of my car and the bitterly cold sea air hit my face. I walked around to the boot, opened it and heaved out a heavy flight case. I slammed the boot shut, locked the car and started walking towards the venue.
This was it. My first gig. I thought about all those weeks of preparation: editing video clips, creating 3-D objects, making coloured patterns, then importing them all into software and configuring effects to change as the music did; targeting frequency, beat, velocity, modifying size, colour, starting point; creating playlists of these… and working out ways to mix them as the music played.
This was it. This was me VJing.
This was all a lifetime (well a decade!) ago.
When I started web designing, VJing took a back seat. I was more interested in interactive layouts, semantic accessible HTML, learning all the IE bugs and mastering the quirks that CSS has to offer. More recently, I have been excited by background gradients, 3-D transforms, the @keyframe directive, as well as new APIs such as getUserMedia, indexedDB, the Web Audio API
But wait, have I just come full circle? Could it be possible, with these wonderful new things in technologies I am already familiar with, that I could VJ again, right here, in a browser?
Well, there’s only one thing to do: let’s try it!
Let’s take to the dance floor
Over the past couple of years working in The Lab I have learned to take a much more iterative approach to projects than before. One of my new favourite methods of working is to create a proof of concept to make sure my theory is feasible, before going on to create a full-blown product. So let’s take the same approach here.
The main VJing functionality I want to recreate is manipulating visuals in relation to sound. So for my POC I need to create a visual, with parameters that can be changed, then get some sound and see if I can analyse that sound to detect some data, which I can then use to manipulate the visual parameters. Easy, right?
So, let’s start at the beginning: creating a simple visual. For this I’m going to create a CSS animation. It’s just a funky i element with the opacity being changed to make it flash.
See the Pen Creating a light by Rumyra (@Rumyra) on CodePen
A note about prefixes: I’ve left them out of the code examples in this post to make them easier to read. Please be aware that you may need them. I find a great resource to find out if you do is caniuse.com. You can also check out all the code for the examples in this article
Start the music
Well, that’s pretty easy so far. Next up: loading in some sound. For this we’ll use the Web Audio API. The Web Audio API is based around the concept of nodes. You have a source node: the sound you are loading in; a destination node: usually the device’s speakers; and any number of processing nodes in between. All this processing that goes on with the audio is sandboxed within the AudioContext.
So, let’s start by initialising our audio context.
var contextClass = window.AudioContext;
if (contextClass) {
//web audio api available.
var audioContext = new contextClass();
} else {
//web audio api unavailable
//warn user to upgrade/change browser
}
Now let’s load our sound file into the new context we created with an XMLHttpRequest.
function loadSound() {
//set audio file url
var audioFileUrl = '/octave.ogg';
//create new request
var request = new XMLHttpRequest();
request.open("GET", audioFileUrl, true);
request.responseType = "arraybuffer";
request.onload = function() {
//take from http request and decode into buffer
context.decodeAudioData(request.response, function(buffer) {
audioBuffer = buffer;
});
}
request.send();
}
Phew! Now we’ve loaded in some sound! There are plenty of things we can do with the Web Audio API: increase volume; add filters; spatialisation. If you want to dig deeper, the O’Reilly Web Audio API book by Boris Smus is available to read online free.
All we really want to do for this proof of concept, however, is analyse the sound data. To do this we really need to know what data we have.
Learning the steps
Let’s take a minute to step back and remember our school days and science class. I’m sure if I drew a picture of a sound wave, we would all start nodding our heads.
The sound you hear is caused by pressure differences in the particles in the air. Sound pushes these particles together, causing vibrations. Amplitude is basically strength of pressure. A simple example of change of amplitude is when you increase the volume on your stereo and the output wave increases in size.
This is great when everything is analogue, but the waveform varies continuously and it’s not suitable for digital processing: there’s an infinite set of values. For digital processing, we need discrete numbers.
We have to sample the waveform at set time intervals, and record data such as amplitude and frequency. Luckily for us, just the fact we have a digital sound file means all this hard work is done for us. What we’re doing in the code above is piping that data in the audio context. All we need to do now is access it.
We can do this with the Web Audio API’s analysing functionality. Just pop in an analysing node before we connect the source to its destination node.
function createAnalyser(source) {
//create analyser node
analyser = audioContext.createAnalyser();
//connect to source
source.connect(analyzer);
//pipe to speakers
analyser.connect(audioContext.destination);
}
The data I’m really interested in here is frequency. Later we could look into amplitude or time, but for now I’m going to stick with frequency.
The analyser node gives us frequency data via the getFrequencyByteData method.
Don’t forget to count!
To collect the data from the getFrequencyByteData method, we need to pass in an empty array (a JavaScript typed array is ideal). But how do we know how many items the array will need when we create it?
This is really up to us and how high the resolution of frequencies we want to analyse is. Remember we talked about sampling the waveform; this happens at a certain rate (sample rate) which you can find out via the audio context’s sampleRate attribute. This is good to bear in mind when you’re thinking about your resolution of frequencies.
var sampleRate = audioContext.sampleRate;
Let’s say your file sample rate is 48,000, making the maximum frequency in the file 24,000Hz (thanks to a wonderful theorem from Dr Harry Nyquist, the maximum frequency in the file is always half the sample rate). The analyser array we’re creating will contain frequencies up to this point. This is ideal as the human ear hears the range 0–20,000hz.
So, if we create an array which has 2,400 items, each frequency recorded will be 10Hz apart. However, we are going to create an array which is half the size of the FFT (fast Fourier transform), which in this case is 2,048 which is the default. You can set it via the fftSize property.
//set our FFT size
analyzer.fftSize = 2048;
//create an empty array with 1024 items
var frequencyData = new Uint8Array(1024);
So, with an array of 1,024 items, and a frequency range of 24,000Hz, we know each item is 24,000 ÷ 1,024 = 23.44Hz apart.
The thing is, we also want that array to be updated constantly. We could use the setInterval or setTimeout methods for this; however, I prefer the new and shiny requestAnimationFrame.
function update() {
//constantly getting feedback from data
requestAnimationFrame(update);
analyzer.getByteFrequencyData(frequencyData);
}
Putting it all together
Sweet sticks! Now we have an array of frequencies from the sound we loaded, updating as the sound plays. Now we want that data to trigger our animation from earlier.
We can easily pause and run our CSS animation from JavaScript:
element.style.webkitAnimationPlayState = "paused";
element.style.webkitAnimationPlayState = "running";
Unfortunately, this may not be ideal as our animation might be a whole heap longer than just a flashing light. We may want to target specific points within that animation to have it stop and start in a visually pleasing way and perhaps not smack bang in the middle.
There is no really easy way to do this at the moment as Zach Saucier explains in this wonderful article. It takes some jiggery pokery with setInterval to try to ascertain how far through the CSS animation you are in percentage terms.
This seems a bit much for our proof of concept, so let’s backtrack a little. We know by the animation we’ve created which CSS properties we want to change. This is pretty easy to do directly with JavaScript.
element.style.opacity = "1";
element.style.opacity = "0.2";
So let’s start putting it all together. For this example I want to trigger each light as a different frequency plays. For this, I’ll loop through the HTML elements and change the opacity style if the frequency gain goes over a certain threshold.
//get light elements
var lights = document.getElementsByTagName('i');
var totalLights = lights.length;
for (var i=0; i<totalLights; i++) {
//get frequencyData key
var freqDataKey = i*8;
//if gain is over threshold for that frequency animate light
if (frequencyData[freqDataKey] > 160){
//start animation on element
lights[i].style.opacity = "1";
} else {
lights[i].style.opacity = "0.2";
}
}
See all the code in action here. I suggest viewing in a modern browser :)
Awesome! It is true — we can VJ in our browser!
Let’s dance!
So, let’s start to expand this simple example. First, I feel the need to make lots of lights, rather than just a few. Also, maybe we should try a sound file more suited to gigs or clubs.
Check it out!
I don’t know about you, but I’m pretty excited — that’s just a bit of HTML, CSS and JavaScript!
The other thing to think about, of course, is the sound that you would get at a venue. We don’t want to load sound from a file, but rather pick up on what is playing in real time. The easiest way to do this, I’ve found, is to capture what my laptop’s mic is picking up and piping that back into the audio context. We can do this by using getUserMedia.
Let’s include this in this demo. If you make some noise while viewing the demo, the lights will start to flash.
And relax :)
There you have it. Sit back, play some music and enjoy the Winamp like experience in front of you.
So, where do we go from here? I already have a wealth of ideas. We haven’t started with canvas, SVG or the 3-D features of CSS. There are other things we can detect from the audio as well. And yes, OK, it’s questionable whether the browser is the best environment for this. For one, I’m using a whole bunch of nonsensical HTML elements (maybe each animation could be held within a web component in the future). But hey, it’s fun, and it looks cool and sometimes I think it’s OK to just dance. |

Keeping Parts of Your Codebase Private on GitHub |
Open source is brilliant, there’s no denying that, and GitHub has been instrumental in open source’s recent success. I’m a keen open-sourcerer myself, and I have a number of projects on GitHub. However, as great as sharing code is, we often want to keep some projects to ourselves. To this end, GitHub created private repositories which act like any other Git repository, only, well, private!
A slightly less common issue, and one I’ve come up against myself, is the desire to only keep certain parts of a codebase private. A great example would be my site, CSS Wizardry; I want the code to be open source so that people can poke through and learn from it, but I want to keep any draft blog posts private until they are ready to go live. Thankfully, there is a very simple solution to this particular problem: using multiple remotes.
Before we begin, it’s worth noting that you can actually build a GitHub Pages site from a private repo. You can keep the entire source private, but still have GitHub build and display a full Pages/Jekyll site. I do this with csswizardry.net. This post will deal with the more specific problem of keeping only certain parts of the codebase (branches) private, and expose parts of it as either an open source project, or a built GitHub Pages site.
N.B. This post requires some basic Git knowledge.
Adding your public remote
Let’s assume you’re starting from scratch and you currently have no repos set up for your project. (If you do already have your public repo set up, skip to the “Adding your private remote” section.)
So, we have a clean slate: nothing has been set up yet, we’re doing all of that now. On GitHub, create two repositories. For the sake of this article we shall call them site.com and private.site.com. Make the site.com repo public, and the private.site.com repo private (you will need a paid GitHub account).
On your machine, create the site.com directory, in which your project will live. Do your initial work in there, commit some stuff — whatever you need to do. Now we need to link this local Git repo on your machine with the public repo (remote) on GitHub. We should all be used to this:
$ git remote add origin git@github.com:[user]/site.com.git
Here we are simply telling Git to add a remote called origin which lives at git@github.com:[user]/site.com.git. Simple stuff. Now we need to push our current branch (which will be master, unless you’ve explicitly changed it) to that remote:
$ git push -u origin master
Here we are telling Git to push our master branch to a corresponding master branch on the remote called origin, which we just added. The -u sets upstream tracking, which basically tells Git to always shuttle code on this branch between the local master branch and the master branch on the origin remote. Without upstream tracking, you would have to tell Git where to push code to (and pull it from) every time you ran the push or pull commands. This sets up a permanent bond, if you like.
This is really simple stuff, stuff that you will probably have done a hundred times before as a Git user. Now to set up our private remote.
Adding your private remote
We’ve set up our public, open source repository on GitHub, and linked that to the repository on our machine. All of this code will be publicly viewable on GitHub.com. (Remember, GitHub is just a host of regular Git repositories, which also puts a nice GUI around it all.) We want to add the ability to keep certain parts of the codebase private. What we do now is add another remote repository to the same local repository. We have two repos on GitHub (site.com and private.site.com), but only one repository (and, therefore, one directory) on our machine. Two GitHub repos, and one local one.
In your local repo, check out a new branch. For the sake of this article we shall call the branch dev. This branch might contain work in progress, or draft blog posts, or anything you don’t want to be made publicly viewable on GitHub.com. The contents of this branch will, in a moment, live in our private repository.
$ git checkout -b dev
We have now made a new branch called dev off the branch we were on last (master, unless you renamed it).
Now we need to add our private remote (private.site.com) so that, in a second, we can send this branch to that remote:
$ git remote add private git@github.com:[user]/private.site.com.git
Like before, we are just telling Git to add a new remote to this repo, only this time we’ve called it private and it lives at git@github.com:[user]/private.site.com.git. We now have one local repo on our machine which has two remote repositories associated with it.
Now we need to tell our dev branch to push to our private remote:
$ git push -u private dev
Here, as before, we are pushing some code to a repo. We are saying that we want to push the dev branch to the private remote, and, once again, we’ve set up upstream tracking. This means that, by default, the dev branch will only push and pull to and from the private remote (unless you ever explicitly state otherwise).
Now you have two branches (master and dev respectively) that push to two remotes (origin and private respectively) which are public and private respectively.
Any work we do on the master branch will push and pull to and from our publicly viewable remote, and any code on the dev branch will push and pull from our private, hidden remote.
Adding more branches
So far we’ve only looked at two branches pushing to two remotes, but this workflow can grow as much or as little as you’d like. Of course, you’d never do all your work in only two branches, so you might want to push any number of them to either your public or private remotes. Let’s imagine we want to create a branch to try something out real quickly:
$ git checkout -b test
Now, when we come to push this branch, we can choose which remote we send it to:
$ git push -u private test
This pushes the new test branch to our private remote (again, setting the persistent tracking with -u).
You can have as many or as few remotes or branches as you like.
Combining the two
Let’s say you’ve been working on a new feature in private for a few days, and you’ve kept that on the private remote. You’ve now finalised the addition and want to move it into your public repo. This is just a simple merge. Check out your master branch:
$ git checkout master
Then merge in the branch that contained the feature:
$ git merge dev
Now master contains the commits that were made on dev and, once you’ve pushed master to its remote, those commits will be viewable publicly on GitHub:
$ git push
Note that we can just run $ git push on the master branch as we’d previously set up our upstream tracking (-u).
Multiple machines
So far this has covered working on just one machine; we had two GitHub remotes and one local repository. Let’s say you’ve got yourself a new Mac (yay!) and you want to clone an existing project:
$ git clone git@github.com:[user]/site.com.git
This will not clone any information about the remotes you had set up on the previous machine. Here you have a fresh clone of the public project and you will need to add the private remote to it again, as above.
Done!
If you’d like to see me blitz through all that in one go, check the showterm recording.
The beauty of this is that we can still share our code, but we don’t have to develop quite so openly all of the time. Building a framework with a killer new feature? Keep it in a private branch until it’s ready for merge. Have a blog post in a Jekyll site that you’re not ready to make live? Keep it in a private drafts branch. Working on a new feature for your personal site? Tuck it away until it’s finished. Need a staging area for a Pages-powered site? Make a staging remote with its own custom domain.
All this boils down to, really, is the fact that you can bring multiple remotes together into one local codebase on your machine. What you do with them is entirely up to you! |

The Responsive Hover Paradigm |
CSS transitions and animations provide web designers with a whole slew of tools to spruce up our designs. Move over ActionScript tweens! The techniques we can now implement with CSS are reminiscent of Flash-based adventures from the pages of web history.
Pairing CSS enhancements with our :hover pseudo-class allows us to add interesting events to our websites. We have a ton of power at our fingertips. However, with this power, we each have to ask ourselves: just because I can do something, should I?
Why bother?
We hear a lot of mantras in the web community. Some proclaim the importance of content; some encourage methods like mobile first to support content; and others warn of the overhead and speed impact of decorative flourishes and visual images. I agree, one hundred percent. At the same time, I believe that content can reign king and still provide a beautiful design with compelling interactions and acceptable performance impacts. Maybe, just maybe, we can even have a little bit of fun when crafting these systems!
Yes, a site with pure HTML content and no CSS will load very fast on your mobile phone, but it leaves a lot to be desired. If you went to your local library and every book looked the same, how would you know which one to borrow? Imagine if every book was printed on the same paper stock with the same cover page in the same type size set at a legible point value… how would you know if you were going to purchase a cookbook about wild game or a young adult story about teens fighting to the death?
For certain audiences, seeing a site with hip, lively hovers sure beats a stale website concept. I’ve worked on many higher education sites, and setting the interactive options is often a very important factor in engaging potential students, alumni, and donors. The same can go for e-commerce sites: enticing your audience with surprise and delight factors can be the difference between a successful and a lost sale.
Knowing your content and audience can help you decide if an intriguing experience is appropriate for your site; if it is, then hover responses can be a real asset.
Why hover?
We have all these capabilities with CSS properties to create the aforementioned fun interactions, and it would be quite easy to fall back into some old patterns and animation abuse. The world of Flash intros and skip links could be recreated with CSS keyframes. However, I don’t think any of us want to go the route of forcing users into unwanted exchanges and road blocking content.
What’s great about utilizing hover to pair with CSS powered actions is that it’s user initiated. It’s a well-established expectation that when a user mouses over an object, something changes. If we can identify that something as a link, then we will expect something to change as we move our mouse over it. By waiting to trigger a CSS-based response until a user chooses to engage with a target makes for a more polished experience (as opposed to barraging our screens with animations all willy-nilly). This makes it the perfect opportunity to add some unique spunk.
What about mobile, touch, and responsive?
So, you’re on board with this so far, but what about mobile and touch devices? Sure, some devices like the Samsung Galaxy S4 have some hovering capabilities, but certainly most do not. Beyond mobile devices, we also have to worry about desktops with touch capabilities. It’s super difficult to detect if a user is currently using touch or hover. One option we have is to design strictly for touch only and send hover enhancements to the graveyard. However, being that I’m all “fuck yeah hovers!,” I like to explore all options. So, let’s examine four different types of hover patterns and see how they can translate to our touch devices.
1. The essential text hover
Changing text color on hover is something we’ve done for a while and it has helped aid in identifying links. To maintain the best accessibility we can achieve, it helps to have a different visual indicator on the default :link state, such as an underline. By making sure all text links have an underline, we won’t have to rely on visual changes during hover to make sure touch device users know that it is a link. For hover-enabled devices, we can add a basic color transition. Doing so creates a nice fade, which makes the change on hover less jarring. Kinda like smooth jazz. The code* to achieve this is quite simple:
a {
color: #6dd4b1;
transition: color 0.25s linear;
}
a:hover, a:focus {
color: #357099;
}
Browser prefixes are omitted
You can see in the final result that, for both touch and hover, everyone wins:
See the Pen Most Basic Link Transition by Jenn Lukas (@Jenn) on CodePen
2. Visual background wizardry and animated hovers
We can take this a step further by again making changes to our aesthetic on hover, but not making any content changes. Altering image hovers for fun and personality can separate your site from others; that personality is important and can enhance our content.
Let’s look at a few sites that do this really well. Scroll down to the judges section of CSS Off and check out the illustrations of the judges. On hover, the illustration fades into a photo of the judge. This provides a realistic alternative to the drawing. Users without the hover can click into the detail page, where they can see the full color picture and learn more about the judges; the information is still available through a different pathway.
Going back to the higher education field, let’s visit Delaware Valley College. The school had recently gone through a rebranding that included loop icons as a symbol to connect ideas. These icons are brought into the website on hover of the slideshow arrows (WebKit browsers). The hover reveals a loop animation, tying in overall themes and adding some extra pizzazz that makes me think, “This is a hip place that feels current.” For visitors who can’t access the hover effect, the default arrow state clearly represents a clickable link, and there is swipe functionality on mobile devices to boot.
DIY.org’s Frontend Dev page has a bunch of enjoyable hover actions happening, featuring scaling transforms and looping animations. Nothing new is revealed on hover, so touch devices won’t miss anything, but it intrigues the user who is visiting a site about front-end dev doing cool front-end things. It backs up its claim of front-end knowledge by adding this enhancement.
The old Cowork Chicago (now redirecting) had a great example, captured here:
Coop: Chicago Coworking from Jenn Lukas on Vimeo.
The code for the Join areas is quite simple:
.join-buttons .daily, .join-buttons .monthly {
height: 260px; z-index: 0; margin-top: 30px;
transition: height .2s linear,margin .2s linear;
}
.join-buttons .daily:hover, .join-buttons .monthly:hover {
height: 280px; margin-top: 20px;
}
li.button:hover {
z-index: 20;
}
The slight rotation on the photos, and the change of color and size of the rate options on hover, add to the fun factor. The site attempts to advertise the co-working space by letting bits of their charisma show through with these transitions. They don’t hit the user over the head with animations, but provide a nice addition to make sure visitors know it’s a welcoming place to work. Some text is added on the hover, but the text isn’t essential to determine where the link goes.
3. Image block hovers
There have been more designs popping up with large image blocks acting as extensive hit area links to subsequent pages. On hover of these links, text is revealed, letting the user know where the link destination goes.
See the Pen Transitioning Max Height by Jenn Lukas (@Jenn) on CodePen
This type of link is tough for users on touch as the image might not provide enough context to reveal its target. If you weren’t aware of what my illustrated avatar from 2007 looked like (or even if you did), then how would you know that this is a link to my Twitter page? Instead, if we provide enough context — such as the @jennlukas handle — you could assume the destination. Users who receive the hover can also see the Twitter bio. It won’t break the experience for users that can’t hover, but it will provide a nice interaction and some more information for those that can.
See the Pen Transitioning Max Height by Jenn Lukas (@Jenn) on CodePen
The Esquire site follows this same pattern, in which the title of the story is shown and the subheading is revealed on hover. Dining at Altitude took the opposite approach, where all text is shown by default and, on hover, you can see more of the image that the text sits atop. This is a nice technique to follow. For touch users, following the link will allow them to see more of the image detail that was revealed on hover.
4. Drop-down navigation menu hovers
Main navigation options that rely on hover have come up as a problem for touch. One way to address this is to be sure your top level items are all functional links to somewhere, and not blank anchors to trigger a submenu drop-down. This ensures that, even without the hover-triggered menu, users can still navigate to those top-level pages. From there, they should be able to access the tertiary pages shown in the drop-down. Following this arrangement, drop-down menus act as a quick shortcut and aren’t necessary to the navigational structure. If the top navigation items are your most visited pages, this execution won’t hinder your visitors.
If the information within the menu is vital, such as a lone account menu, another option is to show drop-down menus on click instead of hover. This pattern will allow both mouse and touch users to access the drop-downs.
Why can’t we just detect hover?
This is a really tricky thing to do. Internet Explorer 10 on Windows 8 uses the aria-haspopup attribute to simulate hover on touch devices, but usually our audience stretches beyond that group. There’s been discussion around using Modernizr, but false positives have come with that. A W3C draft for Media Queries Level 4 includes a hover feature, but it’s not supported yet. Since some devices can hover and touch, should you rely on hover effects for those? Arguments have come up that users can be browsing your site with a mouse and then decide to switch to touch, or vice versa. That might be a large concern for you, or it might be an edge case that isn’t vital to your site’s success.
For one site, I used mousemove and touchstart JavaScript events in order to detect if a visitor starts to browse the site with a mouse. The design initiates for touch users, showing all text on load, but as soon as a mouse movement occurs, the text becomes hidden and is then revealed on hover.
See the Pen Detect Touch devices with mousemove and touchstart by Jenn Lukas (@Jenn) on CodePen
One downside to this approach is that the text is viewable until a mouse enters the document, but if the elements are further down the page it might not be noticed. A second downside is if a user on a touch- and hover-enabled device starts browsing with the mouse and then switches back to touch, the hover-centric styles will remain until a new page load. These were acceptable scenarios in the project I worked on, but might not be for every project.
Can we give our visitors a choice?
I’ve been thinking about how we can combat the concern of not knowing if our customers are using touch or a mouse, not to mention keyboard or Wacom tablets or Minority Report screens. We can cover keyboards with our friend :focus, but that still doesn’t solve our other dilemmas.
Remember when we couldn’t rely on browsers to zoom text and we had to use those small A, medium A, big A [AAA] buttons? On selection of one of those options, a different style sheet would load with small, medium, or large text sizes to satisfy our user’s request. We could even set cookies to remember their font choices. What if we offered a similar solution, a hover/touch switcher, for our new predicament?
See the Pen cwuJf by Jenn Lukas (@Jenn) on CodePen
We could add this switcher to our design. Maybe add it to the header on smaller screens and the footer on larger screens to play the odds. Then be sure to deliver the appropriate touch- or hover-optimized adventure for our guests.
How about adding View options in the areas where we’re hiding content until hover? Looking at Delta Cycle, there’s logic in place to switch layouts on some mobile devices. On desktops we can see the layout shows the product and price by default, and the name of the item and an Add to cart button on hover. If you want to keep this hover, but also worry that touch users can’t access it — or even if you are concerned that people might want to view it with more details up front — we could add another view switcher.
See the Pen List/Grid Views for Hover or Touch by Jenn Lukas (@Jenn) on CodePen
Similar to the list versus grid view we often see in operating systems, a choice here could cover all of our bases.
Conclusion
There is no one-size-fits-all solution when it comes to hover patterns. Design for your content. If you are providing important information about driving directions or healthcare, you might want to err on the side of designing for touch only. If you are behind an educational site and trying to entice more traffic and sign-ups, or a more immersive e-commerce site selling pies, then hover activity can help support your content and engage your visitors without being a detriment. While content can be our top priority, let’s not forget that our designs and interactions, hovers included, can have a great positive impact on how visitors experience our site. Hover wisely, friends. |

Animating Vectors with SVG |
It is almost 2014 and fifteen years ago the W3C started to develop a web-based scalable vector graphics (SVG) format. As web technologies go, this one is pretty old and well entrenched.
See the Pen yJflC by Drew McLellan (@drewm) on CodePen
Embed not working on your device? Try direct.
Unlike rasterized images, SVG files will stay crisp and sharp at any resolution. With high-DPI phones, tablets and monitors, all those rasterized icons are starting to look a bit old and blocky. There are several options to get simpler, decorative pieces to render smoothly and respond to various device widths, shapes and sizes. Symbol fonts are one option; the other is SVG.
I’m a big fan of SVG. SVG is an XML format, which means it is possible to write by hand or to script. The most common way to create an SVG file is through the use of various drawing applications like Illustrator, Inkscape or Sketch. All of them open and save the SVG format.
But, if SVG is so great, why doesn’t it get more attention?
The simple answer is that for a long time it wasn’t well supported, so no one touched the technology. SVG’s adoption has always been hampered by browser support, but that’s not the case any more. Every modern browser (at least three versions back) supports SVG. Even IE9.
Although the browsers support SVG, it is implemented in many different ways.
SVG in HTML
Some browsers allow you to embed SVG right in the HTML: the <svg> element. Treating SVG as a first-class citizen works — sometimes. Another way to embed SVG is via the <img> element; using the src attribute, you can refer to an SVG file. Again, this only works sometimes and leaves you in a tight space if you need to have a fallback for older browsers. The most common solution is to use the <object> element, with the data attribute referencing the SVG file. When a browser does not support this, it falls back to the content inside the <object>. This could be a rasterized fallback <img>. This method gets you the best of both worlds: a nice vector image with an alternative rasterized image for browsers that don’t support SVG. The downside is that you need to manage both formats, and some browsers will download both the SVG and the rasterized version, becoming a performance problem.
Alexey Ten came up with a brilliant little trick that uses inline SVG combined with an SVG <image> element. This has an SVG href pointing to the vector SVG representation and a src attribute to the rasterized version. Older browsers will rewrite the <image> element as <img> and use the rasterized src attribute, but modern browsers will show the vector SVG.
<svg width="96" height="96">
<image xlink:href="svg.svg" src="svg.png" width="96" height="96"/>
</svg>
It is a great workaround for most situations. You will have to determine the browsers you want or need to support and consider performance issues to decide which method is best for you.
So it can be used in HTML. Why?
There are two compelling reasons why vector graphics in the form of icons and symbols are going to be important on the web. With higher resolution screens, going from 72dpi to 200, 300, even over 400dpi, your rasterized icons are looking a little too blocky. As we zoom and print, we expect the visuals on the site to also stay smooth and crisp.
The other main reason vector graphics are useful is scaling. As responsive websites become the norm, we need a way to dynamically readjust the heights, widths and styles of various elements. SVG handles this perfectly, since vectors remain smooth when changing size.
SVG files are text-based, so they’re small and can be gzipped nicely. There are also techniques for creating SVG sprites to further squeeze out performance gains. But SVG really shines when you begin to couple it with JavaScript. Since SVG elements are part of the DOM, they can be interacted with just like any other element you are used to.
The folks at Vox Media had an ingenious little trick with their SVG for a Playstation and Xbox One reviews. I’ve used the same technique for the 24 ways example. Vox Media spent a lot of time creating SVG line art of the two consoles, but once in place the artwork scaled and resized beautifully.
They still had another trick up their sleeves. In their example, they knew each console was line art, so they used SVG’s line dash property to simulate the lines being drawn by animating the growth of the line by small percentage increments until the lines were complete.
This is a great example of a situation where the alternatives wouldn’t be as straightforward to implement. Using an animated GIF would create a heavy file since it would need to contain all the frames of the animation at a large size to permit scaling; even then, smooth aliasing would be lost. canvas and plenty of JavaScript would be another alternative, but this is a rasterized format. It would need be redrawn at each scale, which is certainly possible, but smoothness would be lost when zooming or printing.
The HTML, SVG and JavaScript for this example is less than 4KB! Let’s have a quick look at the code:
<script>
var current_frame = 0;
var total_frames = 60;
var path = new Array();
var length = new Array();
for(var i=0; i<4;i++){
path[i] = document.getElementById('i'+i);
l = path[i].getTotalLength();
length[i] = l;
path[i].style.strokeDasharray = l + ' ' + l;
path[i].style.strokeDashoffset = l;
}
var handle = 0;
var draw = function() {
var progress = current_frame/total_frames;
if (progress > 1) {
window.cancelAnimationFrame(handle);
} else {
current_frame++;
for(var j=0; j<path.length;j++){
path[j].style.strokeDashoffset = Math.floor(length[j] * (1 - progress));
}
handle = window.requestAnimationFrame(draw);
}
};
draw();
</script>
First, we need to initialize a few variables to set the current frame, the number of frames, how fast the animation will run, and we get each of the paths based on their IDs. With those paths, we set the dash and dash offset.
path[i].style.strokeDasharray = l + ' ' + l;
path[i].style.strokeDashoffset = l;
We start the line as a dash, which effectively makes it blank or invisible.
Next, we move to the draw() function. This is where the magic happens. We want to increment the frame to move us forward in the animation and check it’s not finished. If it continues, we then take a percentage of the distance based on the frame and then set the dash offset to this new percentage. This gives the illusion that the line is being drawn. Then we have an animation callback, which starts the draw process over again.
That’s it! It will work with any SVG <path> element that you can draw.
Libraries to get you started
If you aren’t sure where to start with SVG, there are several libraries out there to help. They also abstract all browser compatibility issues to make your life easier.
Raphaël
Snap.svg
svg.js
You can also get most vector applications to export SVG. This means that you can continue your normal workflows, but instead of flattening the image as a PNG or bringing it over to Photoshop to rasterize, you can keep all your hard work as vectors and reap the benefits of SVG. |

Kill It With Fire! What To Do With Those Dreaded FAQs |
In the mid-1640s, a man named Matthew Hopkins attempted to rid England of the devil’s influence, primarily by demanding payment for the service of tying women to chairs and tossing them into lakes.
Unsurprisingly, his methods garnered criticism. Hopkins defended himself in The Discovery of Witches in 1647, subtitled “Certaine Queries answered, which have been and are likely to be objected against MATTHEW HOPKINS, in his way of finding out Witches.”
Each “querie” was written in the voice of an imagined detractor, and answered in the voice of an imagined defender (always referring to himself as “the discoverer,” or “him”):
Quer. 14.
All that the witch-finder doth is to fleece the country of their money, and therefore rides and goes to townes to have imployment, and promiseth them faire promises, and it may be doth nothing for it, and possesseth many men that they have so many wizzards and so many witches in their towne, and so hartens them on to entertaine him.
Ans.
You doe him a great deale of wrong in every of these particulars.
Hopkins’ self-defense was an early modern English FAQ.
Digital beginnings
Question and answer formatting certainly isn’t new, and stretches back much further than witch-hunt days. But its most modern, most notorious, most reviled incarnation is the internet’s frequently asked questions page.
FAQs began showing up on pre-internet mailing lists as a way for list members to answer and pre-empt newcomers’ repetitive questions:
The presumption was that new users would download archived past messages through ftp. In practice, this rarely happened and the users tended to post questions to the mailing list instead of searching its archives. Repeating the “right” answers becomes tedious…
When all the users of a system can hear all the other users, FAQs make a lot of sense: the conversation needs to be managed and manageable. FAQs were a stopgap for the technological limitations of the time.
But the internet moved past mailing lists. Online information can be stored, searched, filtered, and muted; we choose and control our conversations. New users no longer rely on the established community to answer their questions for them.
And yet, FAQs are still around. They’re a content anti-pattern, replicated from site to site to solve a problem we no longer have.
What we hate when we hate FAQs
As someone who creates and structures online content – always with the goal of making that content as useful as possible to people – FAQs drive me absolutely batty. Almost universally, FAQs represent the opposite of useful. A brief list of their sins:
Double trouble
Duplicated content is practically a given with FAQs. They’re written as though they’ll be accessed in a vacuum – but search results, navigation patterns, and curiosity ensure that users will seek answers throughout the site. Is our goal to split their focus? To make them uncertain of where to look? To divert them to an isolated microcosm of the website? Duplicated content means user confusion (to say nothing of the duplicated workload for maintaining content).
Leaving the job unfinished
Many FAQs fail before they’re even out of the gate, presenting a list of questions that’s incomplete (too short and careless to be helpful) or irrelevant (avoiding users’ real concerns in favor of soundbites). Alternately, if the right questions are there, the answers may be convoluted, jargon-heavy, or otherwise difficult to understand.
Long lists of not-my-question
Getting a single answer often means sifting through a haystack of questions. For each potential question, the user must read, comprehend, assess, move on, rinse, repeat. That’s a lot of legwork for little reward – and a lot of opportunity for mistakes. Users may miss their question, or they may fail to recognize a differently worded version of their question, or they may not notice when their sought-after answer appears somewhere they didn’t expect.
The ventriloquist act
FAQs shift the point of view. While websites speak on behalf of the organization (“our products,” “our services,” “you can call us for assistance,” etc.), FAQs speak as the user – “I can’t find my password” or “How do I sign up?” Both voices are written from the first-person perspective, but speak for different entities, which is disorienting: it breaks the tone and messaging across the website. It’s also presumptuous: why do you get to speak for the user?
These all underscore FAQs’ fatal flaw: they are content without context, delivered without regard for the larger experience of the website. You can hear the absurdity in the name itself: if users are asking the same questions so frequently, then there is an obvious gulf between their needs and the site content. (And if not, then we have a labeling problem.)
Instead of sending users to a jumble of maybe-it’s-here-maybe-it’s-not questions, the answers to FAQs should be found naturally throughout a website. They are not separated, not isolated, not other. They are the content.
To present it otherwise is to create a runaround, and users know it. Jay Martel’s parody, “F.A.Q.s about F.A.Q.s” captures the silliness and frustration of such a system:
Q: Why are you so rude?
A: For that answer, you would have to consult an F.A.Q.s about F.A.Q.s about F.A.Q.s. But your time might be better served by simply abandoning your search for a magic answer and taking responsibility for your own profound ignorance.
FAQs aren’t magic answers. They don’t resolve a content dilemma or even help users. Yet they keep cropping up, defiant, weedy, impossible to eradicate.
Where are they all coming from?
Blame it on this: writing is hard. When generating content, most of us do whatever it takes to get some words on the screen. And the format of question and answer makes it easy: a reactionary first stab at content development.
After all, the point of website content is to answer users’ questions. So this – to give everyone credit – is a really good move. Content creators who think in terms of questions and answers are actually thinking of their users, particularly first-time users, trying to anticipate their needs and write towards them.
It’s a good start. But it’s scaffolding: writing that helps you get to the writing you’re supposed to be doing. It supports you while you write your way to the heart of your content. And once you get there, you have to look back and take the scaffolding down.
Leaving content in the Q&A format that helped you develop it is missing the point. You’re not there to build scaffolding. You have to see your content in its naked purpose and determine the best method for communicating that purpose – and it usually won’t be what got you there.
The goal (to borrow a lesson from content management systems) is to separate the content from its presentation, to let the meaning of the content inform its display.
This is, of course, a nice theory.
An occasionally necessary evil
I have a lot of clients who adore FAQs. They’ve developed their content over a long period of time. They’ve listened to the questions their users are asking. And they’ve answered them all on a page that I simply cannot get them to part with.
Which means I’ve had to consider that there may be occasions where an FAQ page is appropriate.
As an example: one of my clients is a financial office in a large institution. Because this office manages several third-party systems that serve a range of niche audiences, they had developed FAQs that addressed hyper-specific instances of dysfunction within systems for different users – à la “I’m a financial director and my employee submitted an expense report in such-and-such system and it returned such-and-such error. What do I do?”
Yes, this content could be removed from the question format and rewritten. But I’m not sure it would be an improvement. It won’t necessarily resolve concerns about length and searchability, and the different audiences may complicate the delivery. And since the work of rewriting it didn’t fit into the client workflow (small team, no writers, pressed for time), I didn’t recommend the change.
I’ve had to make peace with not being to torch all the FAQs on the internet. Some content, like troubleshooting information or complex procedures, may be better in that format. It may be the smartest way for a particular client to handle that particular information.
Of course, this has to be determined on a case-by-case basis, taking into account the amount of content, the subject matter, the skill levels of the content creators, the publishing workflow, and the search habits of the users.
If you determine that an FAQ page is the only way to go, ask yourself:
Is there a better label or more specific term for the page (support, troubleshooting, product concerns, etc.)?
Is there way to structure the page, categorize the questions, or otherwise make it easier for users to navigate quickly to the answer they need?
Is a question and answer format absolutely the best way to communicate this information?
Form follows function
Just as a question and answer format isn’t necessarily required to deliver the content, neither is it an inappropriate method in and of itself. Content professionals have developed a knee-jerk reaction: It’s an FAQ page! Quick, burn it! Buuuuurn it!
But there’s no inherent evil in questions and answers. Framing content in an interrogatory construct is no more a deal with the devil than subheads and paragraphs, or narrative arcs, or bullet points.
Yes, FAQs are riddled with communication snafus. They deserve, more often than not, to be tied to a chair and thrown into a lake. But that wouldn’t fix our content problems. FAQs are a shiny and obvious target for our frustration, but they’re not unique in their flaws. In any format, in any display, in any kind of page, weak content can rear its ugly, poorly written head.
It’s not the Q&A that’s to blame, it’s bad content. Content without context will always fail users. That’s the real witch in our midst. |

How to Make Your Site Look Half-Decent in Half an Hour |
Programmers like me are often intimidated by design – but a little effort can give a huge return on investment. Here are one coder’s tips for making any site quickly look more professional.
I am a programmer. I am not a designer. I have a degree in computer science, and I don’t mind Comic Sans. (It looks cheerful. Move on.)
But although I am a programmer, I want to make my sites look attractive. This is partly out of vanity, and partly realism. Vanity because I want people to think my work is good, and realism because the research shows that people won’t think a site is credible unless it also looks attractive.
For a very long time after I became a programmer, I was scared of design. Design seemed to consist of complicated rules that weren’t written down anywhere, plus an unlearnable sense of taste, possessed only by a black-clad elite.
But a little while ago, I decided to do my best to hack what it took to make my own projects look vaguely attractive. And although this doesn’t come close to the effect a professional designer could achieve, gathering these resources for improving a site’s look and feel has been really helpful.
If I hadn’t figured out some basic design shortcuts, it’s unlikely that a weekend hack of mine would have ended up on page three of the Daily Mail. And too often now, I see excellent programming projects that don’t reach the audience they deserve, simply because their design doesn’t match their execution.
So, if you are a developer, my Christmas present to you is this: my own collection of hacks that, used rightly, can make your personal programming projects look professional, quickly. None are hard to learn, most are free, and they let you focus on writing code.
One thing to note about these tips, though. They are a personal, pragmatic compilation. They are suggestions, not a definitive guide. You will definitely get better results by working with a professional designer, and by studying design more deeply.
If you are a designer, I would love to hear your suggestions for the best tools that I’ve missed, and I’d love to know how we programmers can do things better.
With that, on to the tools…
1. Use Bootstrap
If you’re not already using Bootstrap, start now. I really think that Bootstrap is one of the most significant technical achievements of the last few years: it democratizes the whole process of web design.
Essentially, Bootstrap is a a grid system, with a bunch of common elements. So you can lay your site out how you want, drop in simple elements like forms and tables, and get a good-looking, consistent result, without spending hours fiddling with CSS. You just need HTML.
Another massive upside is that it makes it easy to make any site responsive, so you don’t have to worry about writing media queries. Go, get Bootstrap and check out the examples. To keep your site lightweight, you can customize your download to include only the elements you want.
If you have more time, then Mark Otto’s article on why and how Bootstrap was created at Twitter is well worth a read.
2. Pimp Bootstrap
Using Bootstrap is already a significant advance on not using Bootstrap, and massively reduces the tedium of front-end development. But you also run the risk of creating Yet Another Bootstrap Site, or Hack Day Design, as it’s known.
If you’re really pressed for time, you could buy a theme from Wrap Bootstrap. These are usually created by professional designers, and will give a polish that we can’t achieve ourselves. Your site won’t be unique, but it will look good quickly.
Luckily, it’s pretty easy to make Bootstrap not look too much like Bootstrap – using fonts, CSS effects, background images, colour schemes and so on. Most of the rest of this article covers different ways to achieve this.
We are going to customize this Bootstrap example page.
This already has some custom CSS in the <head>. We’ll pull it all out, and create a new CSS file, custom.css. Then we add a reference to it in the header. Now we’re ready to start customizing things.
3. Fonts
Web fonts are one of the quickest ways to make your site look distinctive, modern, and less Bootstrappy, so we’ll start there.
First, we can add some sweet fonts, from Google Web Fonts. The intimidating bit is choosing fonts that look nice together. Luckily, there are plenty of suggestions around the web: we’re going to use one of DesignShack’s suggested free Google Fonts pairings. Our fonts are Corben (for headings) and Nobile (for body copy).
Then we add these files to our <head>.
<link href="http://fonts.googleapis.com/css?family=Corben:bold" rel="stylesheet" type="text/css">
<link href="http://fonts.googleapis.com/css?family=Nobile" rel="stylesheet" type="text/css">
…and this to custom.css:
h1, h2, h3, h4, h5, h6 {
font-family: 'Corben', Georgia, Times, serif;
}
p, div {
font-family: 'Nobile', Helvetica, Arial, sans-serif;
}
Now our example looks like this. It’s not going to win any design awards, but it’s immediately better:
I also recommend the web font services Fontdeck, or Typekit – these have a wider selection of fonts, and are worth the investment if you regularly need to make sites look good. For more font combinations, Just My Type suggests appealing pairings from Typekit. Finally, you can experiment with type pairing ideas at Type Connection. For the design background on pairing fonts, Typekit’s post is worth a read.
4. Textures
An instant way to make a site look classy is to use textures. You know the grey, stripy, indefinably elegant background on 24ways.org? That.
If only there was a superb resource listing attractive, free, ready-to-use textures… Oh wait, there’s Atle Mo’s Subtle Patterns.
We’re going to use Cream Dust, for an effect that can only be described as subtle. We download the file to a new /img/ directory, then add this to the CSS file:
body {
background: url(/img/cream_dust.png) repeat 0 0;
}
Bang:
For some design background on patterns, I recommend reading through Smashing Magazine’s guidelines on textures. (TL;DR version: use textures to enhance beauty, and clarify the information architecture of your site; but don’t overdo it, or inadvertently obscure your text.)
Still more to do, though. Onwards.
5. Icons
Last year’s 24 ways taught us to use icon fonts for our site icons.
This is great for the time-pressed coder, because icon fonts don’t just cut down on HTTP requests – they’re a lot quicker to set up than image-based icons, too.
Bootstrap ships with an extensive, free for commercial use icon set in the shape of Font Awesome. Its icons are safe for screen readers, and can even be made to work in IE7 if needed (we’re not going to bother here).
To start using these icons, just download Font Awesome, and add the /fonts/ directory to your site and the font-awesome.css file into your /css/ directory. Then add a reference to the CSS file in your header:
<link rel="stylesheet" href="/css/font-awesome.css">
Finally, we’ll add a truck icon to the main action button, as follows. Why a truck? Why not?
<a class="btn btn-large btn-success" href="#"><i class="icon-truck"></i> Sign up today</a>
We’ll also tweak our CSS file to stop the icon nudging up against the button text:
.jumbotron .btn i {
margin-right: 8px;
}
And this is how it looks:
Not the most exciting change ever, but it livens up the page a bit. The licence is CC-BY-3.0, so we also include a mention of Font Awesome and its URL in the source code.
If you’d like something a little more distinctive, Shifticons lets you pay a few cents for individual icons, with the bonus that you only have to serve the icons you actually use, which is more efficient. Its icons are also friendly to screen readers, but won’t work in IE7.
6. CSS3
The next thing you could do is add some CSS3 goodness. It can really help the key elements of the site stand out.
If you are pressed for time, just adding box-shadow and text-shadow to emphasize headings and standouts can be useful:
h1 {
text-shadow: 1px 1px 1px #ccc;
}
.div-that-you want-to-stand-out {
box-shadow: 0 0 1em 1em #ccc;
}
We have a little more time though, so we’re going to do something more subtle. We’ll add a radial gradient behind the main heading, using an online gradient editor.
The output is hefty, but you can see it in the CSS. Note that we also need to add the following to our HTML, for IE9 support:
<!--[if gte IE 9]>
<style type="text/css">
.gradient {
filter: none;
}
</style>
<![endif]-->
And the effect – I don’t know what a designer would think, but I like the way it makes the heading pop.
For a crash course in useful modern CSS effects, I highly recommend CodeSchool’s online course in Functional HTM5 and CSS3. It costs money ($25 a month to subscribe), but it’s worth it for the time you’ll save. As a bonus, you also get access to some excellent JavaScript, Ruby and GitHub courses.
(Incidentally, if you find yourself fighting with basic float and display attributes in CSS – and there’s no shame in it, CSS layout is not intuitive – I recommend the CSS Cross-Country course at CodeSchool.)
7. Add a twist
We could leave it there, but we’re going to add a background image, and give the site some personality.
This is the area of design that I think many programmers find most intimidating. How do we create the graphics and photographs that a designer would use? The answer is iStockPhoto and its competitors – online image libraries where you can find and pay for images. They won’t be unique, but for our purposes, that’s fine.
We’re going to use a Christmassy image. For a twist, we’re going to use Backstretch to make it responsive.
We must pay for the image, then download it to our /img/ directory. Then, we set it as our <body>’s background-image, by including a JavaScript file with just the following line:
$.backstretch("/img/winter.jpg");
We also reset the subtle pattern to become the background for our container image. It would look much better transparent, so we can use this technique in GIMP to make it see-through:
.container-narrow {
background: url(/img/cream_dust_transparent.png) repeat 0 0;
}
We also fiddle with the padding on body and .container-narrow a bit, and this is the result:
(Aside: If this were a real site, I’d want to buy images in multiple sizes and ensure that Backstretch chose the most appropriately sized image for our screen, perhaps using responsive images.)
How to find the effects that make a site interesting? I keep a set of bookmarks for interesting JavaScript and CSS effects I might want to use someday, from realistic shadows to animating grids. The JavaScript Weekly newsletter is a great source of ideas.
8. Colour schemes
We’re just about getting there – though we’re probably past half an hour now – but that button and that menu still both look awfully Bootstrappy.
Real sites, with real designers, have a colour palette, carefully chosen to harmonize and match the brand profile. For our purposes, we’re just going to borrow some colours from the image. We use Gimp’s colour picker tool to identify the hex values of the blue of the snow. Then we can use Color Scheme Designer to find contrasting, but complementary, colours.
Finally, we use those colours for our central button. There are lots of tools to help us do this, such as Bootstrap Buttons. The new HTML is quite long, so I won’t paste it all here, but you can find it in the CSS file.
We also reset the colour of the pills in the navigation menu, which is a bit easier:
.nav-pills > .active > a, .nav-pills > .active > a:hover {
background-color: #FF9473;
}
I’m not sure if the result is great to be honest, but at least we’ve lost those Bootstrap-blue buttons:
Another way to do it, if you didn’t have an image to match, would be to borrow an attractive colour scheme. Colourlovers is a community where people create and share ready-made colour palettes.
The key thing is to find a palette with an open licence, so you can legitimately use it. Unfortunately, you can’t search for palettes by licence type, but many do have open licences. Here’s a popular palette with a CC-BY-SA licence that allows reuse with attribution.
As above, you can use the hex values from the palette in your custom CSS, and bask in the newly colourful results.
9. Read on
With the above techniques, you can make a site that is starting to look slightly more professional, pretty quickly.
If you have the time to invest, it’s well worth learning some design principles, if only so that design seems less intimidating and more like fun. As part of my design learning, I read a few introductory design books aimed at coders. The best I found was David Kadavy’s Design for Hackers: Reverse-Engineering Beauty, which explains the basic principles behind choosing colours, fonts, typefaces and layout.
In the introduction to his book, David writes:
No group stands to gain more from design literacy than hackers do… The one subject that is exceedingly frustrating for hackers to try to learn is design. Hackers know that in order to compete against corporate behemoths with just a few lines of code, they need to have good, clear design, but the resources with which to learn design are simply hard to find.
Well said. If you have half a day to invest, rather than half an hour, I recommend getting hold of David’s book.
And the journey is over. Perhaps that took slightly more than half an hour, but with practice, using the above techniques can become second nature. What useful tools have I missed? Designers, how would you improve on the above? I would love to know, so please give me your views in the comments. |

Should We Be Reactive? |
Evolution
Looking at the evolution of the web and the devices we use should help remind us that the times we’re adjusting to are just another step on a journey. These times seem to be telling us that we need to embrace flexibility.
Imagine an HTML file containing nothing but text. It’s viewable on any web-capable device and reasonably readable: the notion of the universality of the web was very much a founding principle. Right from the beginning, browser vendors understood that we’d want text to reflow (why wouldn’t we?), so I consider the first websites to have been fluid.
As we attempted to exert more control through our designs in the early days of the web, debates about whether we should produce fixed or fluid sites raged. We could create fluid designs using tables, but what we didn’t have then was a wide range of web capable devices or the ability to control this fluidity. The biggest changes occurred when stats showed enough people using a different screen resolution we could cater for.
To me, the techniques of responsive web design provide the control we were missing. Combining new approaches to layout and images with media queries empowered us to learn how to embrace the inherent flexibility of the web in ways to suit our work and the devices used by our audience.
Perhaps another kind of flexibility might be found in how we use context to affect how we present our content; to consider how we might use the information we can access from people, browsers and devices to provide web experiences – effectively creating sites that react to initial or changing circumstances in the relationship between people and our content.
Embracing flexibility
So what is context? Put simply, you could think of it as a secondary piece of information that helps clarify the meaning of the first. It helps set a scene or describe circumstances. I think that Cennydd Bowles has summed it up really well through talks he’s given recently, in which he’s arrived at the acronym DETAILS (Device, Environment, Time, Activity, Individual, Location, Social) – I encourage you to keep an eye out for his next book due in the new year where he’ll explore this idea much further. This clarity over what context could mean in terms of what we do on the web is fundamental, directing us towards ways we might use it.
When you stop to think about it, we’ve been using some basic pieces of this information right from the beginning, like bits of JavaScript or Java applets that serve an appropriate greeting to your site’s visitors, or show their location, or even local weather. But what if we think of this from the beginning of our projects?
We should think about our content first. Once we know this and have a direction, perhaps then we can think about what context, or even multiple contexts, might help us to communicate more effectively.
The real world
There’s always been a disconnect between the real world and the web, which is to be expected. But the world around us is a sea of data; every fundamental building block: people, places, events and things have information waiting to be explored.
For sites based around physical objects or locations, this divide is really apparent. We don’t ordinarily take the time to describe in code the properties of a place, or consider whether your relationship to the place in the real world should have any impact on your relationship with a site about it.
When I think about local businesses, they have such rich properties to draw on and yet we don’t really explore them in any meaningful way, even through something as simple as opening hours.
Now we have data…
We’ve long had access to the current time both on server- and client-sides. The use of geolocation is easier than ever, but when we look at the range of information we could glean to help us make some choices, maybe there’s some help on the horizon from projects like the W3C Device APIs Working Group. This might prove useful to help make us aware of network and battery conditions of a device, along with the potential to gain data from other sensors, which could tell us about lighting conditions, ambient noise levels and temperature depending on the capabilities of the device.
It may be that our sites have some form of login or access to your profile from another site. Along with data from our devices and browsers, this should give us a sense of how best to talk to our audience in certain situations. We don’t necessarily need to know any personal details, just enough to make decisions about how to present our sites.
The reactive web?
So why reactive web design? I’m hoping that a name might help us to have a common vocabulary not only about what we mean when we talk about context, but how it could be considered through our projects, right from the early stages. How could this manifest itself?
A simple example might be a location-aware panel on your site. Perhaps the space is a little down in your content hierarchy but serves a perfectly valid purpose by default. To visitors outside the country perhaps this works fine, but within your country maybe this panel could be used to communicate more effectively. Further still, if we knew the visitors were in the vicinity, we could talk to them more directly.
What if both time and location were relevant? This space could work as before but you could consider how time could intersect with your local audience. If you know they’re local and it’s a certain time of day, you could communicate directly with them.
This example isn’t beyond what banner ads often do and uses easily accessible information. There are more unusual combinations we may be able to find, such as movement and presence. Perhaps a site that tells a story, which changes design and content based on whether you’re moving, how long you’ve been on the site and how far you’ve travelled. This isn’t what we typically expect from websites, but we should bear in mind that what websites are now will not be what they become in the future.
You could do much of this contextual presentation through native apps, of course. The Silent History, an app novel written and designed for iPad and iPhone, uses an exploration element, providing “hundreds of location-based stories across the U.S. and around the world. These can be read only when your device’s GPS matches the coordinates of the specified location.” But considering the universality of the web, we could redefine what web-based experiences should be like. Not all methods would work well on the web, but that’s a decision that has to be made for a specific project.
By thinking more broadly about any web-capable device, we can use what we know to provide relevant experiences for our site’s visitors. We need to be sure what we mean by relevant, of course!
Reality bites
While there are incredible possibilities, from a simple panel on a site to something bordering on living sites that evolve and change with our circumstances, we need to act with a degree of pragmatism and understand how much of what we could do is based on assumptions and the bias of our own experiences.
We could go wild with changing the way our content is presented based on contextual information, but if we’re not careful what we end up with confuses and could provide a very fractured experience. As much as possible we need to think more ethnographically, observe and question people in the situations we think may be relevant, and test our assumptions as early as we can. Even on small projects, there may be ways we can validate our assumptions and test with our audience. The key to applying contextual content or cues is not to break the experience between contextual views (as I think we now wouldn’t when hiding content on a mobile view).
It’s another instance of progressive enhancement – as we know certain pieces of information, we can enhance the experience. Also, if you do change content, how can you not make a more cumbersome experience for your visitors?
It’s all about communication
Content is at the core of what we do, but if we consider context we need to understand the impact on that. The effect could be as subtle as an altered hierarchy, involve swapping out panels of content, or in extreme instances perhaps all of your content might change. In some ways, this extends the notion of adaptive content that Karen McGrane has been talking about, to how we write and store the content we create. Thinking about the the impact of context may require us to re-evaluate our site structure, too. Whatever we decide, we have to be clear what will happen and manage the expectations of our users.
The bottom line
What I’m proposing isn’t that we go crazy and end up with a confused, disjointed set of experiences across the web. What I hope is that starting right from the beginning of a project, we think about what context is and could be, and see what relevance it might have to what we’re trying to communicate. This strategic process leads us to think about design.
We are slowly adapting to what it means to be flexible through responsive and adaptive processes. What does thinking about contextual states mean to us (or designing for state in general)? Does this highlight again how difficult it’ll be for our tools to keep up with our processes and output?
In terms of code, the vast majority of this data comes from the client-side through JavaScript. While we can progressively enhance, this could lead to a lot of code bloat through feature or capability detection, and potentially a lot of conditional loading of scripts. It’s a real shame we don’t get much we can rely on from the server-side – we know how unreliable user agents are!
We need to understand why we’d do this. Are we trying to communicate well and be useful, or doing it to show off? Underneath it all, what do we base our decisions on? Do we have actual insight or are we proceeding from our assumptions and the bias of our own experiences? Scott Jenson summed it up best for me: (to paraphrase) the pain we put people through has to be greatly outweighed by the value we offer.
I see that this could be another potential step in our evolution on the web; continuing this exploration of the flexibility the web allows us. It’s amazing we can do such incredible things from what is essentially a set of disparate, linked documents. |

A Harder-Working Class |
Class is only becoming more important. Focusing on its original definition as an attribute for grouping (or classifying) as well as linking HTML to CSS, recent front-end development practices are emphasizing class as a vessel for structured, modularized style packages. These patterns reduce the need for repetitive declarations that can seriously bloat file sizes, and instil human-readable understanding of how the interface, layout, and aesthetics are constructed.
In the next handful of paragraphs, we will look at how these emerging practices – such as object-oriented CSS and SMACSS – are pushing the relevance of class. We will also explore how HTML and CSS architecture can be further simplified, performance can be boosted, and CSS utility sharpened by combining class with the attribute selector.
A primer on attribute selectors
While attribute selectors were introduced in the CSS 2 spec, they are still considered rather exotic. These well-established and well-supported features give us vastly improved flexibility in targeting elements in CSS, and offer us opportunities for smarter markup. With an attribute selector, you can directly style an element based on any of its unique – or uniquely shared – attributes, without the need for an ID or extra classes. Unlike pseudo-classes, pseudo-elements, and other exciting features of CSS3, attribute selectors do not require any browser-specific syntax or prefix, and are even supported in Internet Explorer 7.
For example, say we want to target all anchor tags on a page that link to our homepage. Where otherwise we might need to manually identify and add classes to the HTML for these specific links, we could simply write:
[href=index.html] { }
This selector reads: target every element that has an href attribute of “index.html”.
Attribute selectors are more faceted, though, as they also give us some very simple regular expression-like logic that helps further narrow (or widen) a selector’s scope. In our previous example, what if we wanted to also give indicative styles to any anchor tag linking to an external site? With no way to know what the exact href value would be for every external link, we need to use an expression to match a common aspect of those links. In this case, we know that all external links need to start with “http”, so we can use that as a hook:
[href^=http] { }
The selector here reads: target every element that has an href attribute that begins with “http” (which will also include “https”). The ^= means “starts with”. There are a few other simple expressions that give us a lot of flexibility in targeting elements, and I have found that a deep understanding of these and other selector types to be very useful.
The class-attribute selector
By matching classes with the attribute selector, CSS can be pushed to accomplish some exciting new feats. What I call a class-attribute selector combines the advantages of classes with attribute selectors by targeting the class attribute, rather than a specific class. Instead of selecting .urgent, you could select [class*=urgent]. The latter may seem like a more verbose way of accomplishing the former, but each would actually match two subtly different groups of elements.
Eric Meyer first explored the possibility of using classes with attribute selectors over a decade ago. While his interest in this technique mostly explored the different facets of the syntax, I have found that using class-attribute selectors can have distinct advantages over either using an attribute selector or a straightforward class selector.
First, let’s explore some of the subtleties of why we would target class before other attributes:
Classes are ubiquitous. They have been supported since the HTML 4 spec was released in 1999. Newer attributes, such as the custom data attribute, have only recently begun to be adopted by browsers.
Classes have multiple ways of being targeted. You can use the class selector or attribute selector (.classname or [class=classname]), allowing more flexible specificity than resorting to an ID or !important.
Classes are already widely used, so adding more classes will usually require less markup than adding more attributes.
Classes were designed to abstractly group and specify elements, making them the most appropriate attribute for styling using object-oriented methods (as we will learn in a moment).
Also, as Meyer pointed out, we can use the class-attribute selector to be more strict about class declarations. Of these two elements:
<h2 class="very urgent">
<h2 class="urgent">
…only the second h2 would be selected by [class=urgent], while .urgent would select both. The use of = matches any element with the exact class value of “urgent”. Eric explores these nuances further in his series on attribute selectors, but perhaps more dramatic is the added power that class-attribute selectors can bring to our CSS.
More object-oriented, more scalable and modular
Nicole Sullivan has been pushing abstracted, object-oriented thinking in CSS development for years now. She has shared stacks of knowledge on how behemoth sites have seen impressive gains in maintenance overhead and CSS file sizes by leaning heavier on classes derived from common patterns. Jonathan Snook also speaks, writes and is genuinely passionate about improving our markup by using more stratified and modular class name conventions. With SMACSS, he shows this to be highly useful across sites – both complex and simple – that exhibit repeated design patterns. Sullivan and Snook both push the use of class for styling over other attributes, and many front-end developers are fast advocating such thinking as best practice.
With class-attribute selectors, we can further abstract our CSS, pushing its scalability. In his chapter on modules, Snook gives the example of a .pod class that might represent a certain set of styles. A .pod style set might be used in varying contexts, leading to CSS that might normally look like this:
.pod { }
form .pod { }
aside .pod { }
According to Snook, we can make these styles more portable by targeting more verbose classes, rather than context:
.pod { }
.pod-form { }
.pod-sidebar { }
…resulting in the following HTML:
<div class="pod">
<div class="pod pod-form">
<div class="pod pod-sidebar">
This divorces the <div>’s styles from its context, making it applicable to any situation in which it is needed. The markup is clean and portable, and the classes are imbued with meaning as to what module they belong to.
Using class-attribute selectors, we can simplify this further:
[class*=pod] { }
.pod-form { }
.pod-sidebar { }
The *= tells the browser to look for any element with a class attribute containing “pod”, so it matches “pod”, “pod-form”, “pod-sidebar”, etc. This allows only one class per element, resulting in simpler HTML:
<div class="pod">
<div class="pod-form">
<div class="pod-sidebar">
We could further abstract the concept of “form” and “sidebar” adjustments if we knew that each of those alterations would always need the same treatment.
/* Modules */
[class*=pod] { }
[class*=btn] { }
/* Alterations */
[class*=-form] { }
[class*=-sidebar] { }
In this case, all elements with classes appended “-form” or “-sidebar” would be altered in the same manner, allowing the markup to stay simple:
<form>
<h2 class="pod-form">
<a class="btn-form" href="#">
<aside>
<h2 class="pod-sidebar">
<a class="btn-sidebar" href="#">
50+ shades of specificity
Classes are just powerful enough to override element selectors and default styling, but still leave room to be trumped by IDs and !important styles. This makes them more suitable for object-oriented patterns and helps avoid messy specificity issues that can not only be a pain for developers to maintain, but can also affect a site’s performance. As Sullivan notes, “In almost every case, classes work well and have fewer unintended consequences than either IDs or element selectors”. Proper use of specificity and cascade is crucial in building straightforward, efficient CSS.
One interesting aspect of attribute selectors is that they can be compounded for increasing levels of specificity. Attribute selectors are assigned a specificity level of ten, the same as class selectors, but both class and attribute selectors can be chained together, giving them more and more specificity with each link. Some examples:
.box { }
/* Specificity of 10 */
.box.promo { }
/* Specificity of 20 */
[class*=box] { }
/* Specificity of 10 */
[class*=box][class*=promo] { }
/* Specificity of 20 */
You can chain both types together, too:
.box[class*=promo] { }
/* Specificity of 20 */
I was amused to find, though, that you can chain the exact same class and attribute selectors for infinite levels of specificity
.box { }
/* Specificity of 10 */
.box.box { }
/* Specificity of 20 */
.box.box.box { }
/* Specificity of 30 */
[class*=box] { }
/* Specificity of 10 */
[class*=box][class*=box] { }
/* Specificity of 20 */
[class*=box][class*=box][class*=box] { }
/* Specificity of 30 */
.box[class*=box].box[class*=box] { }
/* Specificity of 40 */
To override .box styles for promo, we wouldn’t need to add an ID, change the order of .promo and .box in the CSS, or resort to an !important style. Granted, any issue that might need this fine level of specificity tweaking could probably be better solved with clever cascades, but having options never hurts.
Smarter CSS
One of the most powerful aspects of the class-attribute selector is its ability to expand the simple logic found in CSS. When developing Gridset (an online tool for building grids and outputting them as CSS), I realized that with the right class name conventions, class-attribute selectors would allow the CSS to be smart enough to automatically adjust for column offsets without the need for extra classes. This imbued the CSS output with logic that other frameworks lacked, and makes a developer’s job much easier.
Say you need an element that spans column five (c5) to column six (c6) on your grid, and is preceded by an element spanning column one (c1) to column three (c3). The CSS can anticipate such a scenario:
.c1-c3 + .c5-c6 {
margin-left: 25%; /* …or the width of column four plus two gutter widths */
}
…but to accommodate all of the margin offsets that could span that same gap, we would need to write a rather protracted list for just a six column grid:
.c1-c3 + .c5-c6,
.c1-c3 + .c5,
.c2-c3 + .c5-c6,
.c2-c3 + .c5,
.c3 + .c5-c6,
.c3 + .c5 {
margin-left: 25%;
}
Now imagine how the verbosity compounds when we repeat this type of declaration for every possible margin in a grid. The more columns added to the grid, the longer this selector list would get, too, making the CSS harder for the developer to maintain and slowing the load time. Using class-attribute selectors, though, this can be much simpler:
[class*=c3] + [class*=c5] {
margin-left: 25%;
}
I’ve detailed how we extract as much logic as possible from as little CSS as needed on the Gridset blog.
More flexible selectors
In a recent project, I was working with Drupal-generated classes to change styles for certain special pages on a site. Without being able to change the code base, I was left trying to find some specific aspect of the generated HTML to target. I noticed that every special page was given a prefixed class, unique to the page, resulting in CSS like this:
.specialpage-about,
.specialpage-contact,
.specialpage-info,
…
…and the list kept growing with each new special page. Such bloat would lead to problems down the line, and add development overhead to editorial decisions, which was a situation we were trying to avoid. I was easily able to fix this, though, with a concise class-attribute selector:
[class*=specialpage-]
The CSS was now flexible enough to accommodate both the editorial needs of the client, and the development restrictions of the CMS.
Selector performance
As Snook tells us in his chapter on Selector Performance, selectors are read by the browser from right to left, matching every element that adheres to each rule (or part of the selector). The more specific we can make the right-most rules – and every other part of your selectors – the more performant your CSS will be. So this selector:
.home-page .promo .main-header
…would be more performant than:
.home-page div header
…because there are likely many more header and div elements on the page, but not so many elements with those specific classes.
Now, the class-attribute selector could be more general than a class selector, but not by much. I ran numerous tests based on the work of Steve Souders (and a few others) to test a class-attribute selector against a normal class selector. Given that Javascript will freeze during style rendering, I created a script that will add, then remove, a stylesheet on a page 5000 times, and measure only the time that elapses during the rendering freeze. The script runs four tests, essentially: one where a class selector and class-attribute Selector match a single element, and one they match multiple elements on the page.
After running the test over 100 times and averaging the results, I have not seen a significant difference in rendering times. (As of this writing, the class-attribute selector has been 0.398% slower on average.) View the results here.
Given the sheer amount of bytes potentially saved by reducing selector lists, though, I am confident class-attribute selectors could shorten load times on larger sites and, at the very least, save precious development time.
Conclusion
With its flexibility and broad remit, class has at times been derided as too lenient, allowing CMSes and lazy developers to fill its values with presentational hacks or verbose gibberish. There have even been calls for an early retirement. Class continues, though, to be one of our most crucial tools.
Front-end developers are rightfully eager to expand production abilities through innovations such as Sass or LESS, but this should not preclude us from honing the tools we already know as well. Every technique demonstrated in this article was achievable over a decade ago and most of the same thinking could be applied to IDs, rels, or any other attribute (though the reasons listed above give class an edge). The recent advent of methods such as object-oriented CSS and SMACSS shows there is still much room left to expand what simple HTML and CSS can accomplish. Progress may not always be found in the innovation of our tools, but through sharpening our understanding of them. |

Giving CSS Animations and Transitions Their Place |
CSS animations and transitions may not sit squarely in the realm of the behaviour layer, but they’re stepping up into this area that used to be pure JavaScript territory. Heck, CSS might even perform better than its JavaScript equivalents in some cases. That’s pretty serious! With CSS’s new tricks blurring the lines between presentation and behaviour, it can start to feel bloated and messy in our CSS files. It’s an uncomfortable feeling.
Here are a pair of methods I’ve found to be pretty helpful in keeping the potential bloat and wire-crossing under control when CSS has its hands in both presentation and behaviour.
Same eggs, more baskets
Structuring your CSS to have separate files for layout, typography, grids, and so on is a fairly common approach these days. But which one do you put your transitions and animations in? The initial answer, as always, is “it depends”.
Small effects here and there will likely sit just fine with your other styles. When you move into more involved effects that require multiple animations and some logic support from JavaScript, it’s probably time to choose none of the above, and create a separate CSS file just for them.
Putting all your animations in one file is a huge help for code organization. Even if you opt for a name less literal than animations.css, you’ll know exactly where to go for anything CSS animation related. That saves time and effort when it comes to editing and maintenance. Keeping track of which animations are still currently used is easier when they’re all grouped together as well. And as an added bonus, you won’t have to look at all those horribly unattractive and repetitive prefixed @-keyframe rules unless you actually need to.
An animations.css file might look something like the snippet below. It defines each animation’s keyframes and defines a class for each variation of that animation you’ll be using. Depending on the situation, you may also want to include transitions here in a similar way. (I’ve found defining transitions as their own class, or mixin, to be a huge help in past projects for me.)
// defining the animation
@keyframes catFall {
from { background-position: center 0;}
to {background-position: center 1000px;}
}
@-webkit-keyframes catFall {
from { background-position: center 0;}
to {background-position: center 1000px;}
}
@-moz-keyframes catFall {
from { background-position: center 0;}
to {background-position: center 1000px;}
}
@-ms-keyframes catFall {
from { background-position: center 0;}
to {background-position: center 1000px;}
}
…
// class that assigns the animation
.catsBackground {
height: 100%;
background: transparent url(../endlessKittens.png) 0 0 repeat-y;
animation: catFall 1s linear infinite;
-webkit-animation: catFall 1s linear infinite;
-moz-animation: catFall 1s linear infinite;
-ms-animation: catFall 1s linear infinite;
}
If we don’t need it, why load it?
Having all those CSS animations and transitions in one file gives us the added flexibility to load them only when we want to. Loading a whole lot of things that will never be used might seem like a bit of a waste.
While CSS has us impressed with its motion chops, it falls flat when it comes to the logic and fine-grained control. JavaScript, on the other hand, is pretty good at both those things. Chances are the content of your animations.css file isn’t acting alone. You’ll likely be adding and removing classes via JavaScript to manage your CSS animations at the very least. If your CSS animations are so entwined with JavaScript, why not let them hang out with the rest of the behaviour layer and only come out to play when JavaScript is supported?
Dynamically linking your animations.css file like this means it will be completely ignored if JavaScript is off or not supported. No JavaScript? No additional behaviour, not even the parts handled by CSS.
<script>
document.write('<link rel="stylesheet" type="text/css" href="animations.css">');
</script>
This technique comes up in progressive enhancement techniques as well, but it can help here to keep your presentation and behaviour nicely separated when more than one language is involved. The aim in both cases is to avoid loading files we won’t be using.
If you happen to be doing something a bit fancier – like 3-D transforms or critical animations that require more nuanced fallbacks – you might need something like modernizr to step in to determine support more specifically. But the general idea is the same.
Summing it all up
Using a couple of simple techniques like these, we get to pick where to best draw the line between behaviour and presentation based on the situation at hand, not just on what language we’re using. The power of when to separate and how to reassemble the individual pieces can be even greater if you use preprocessors as part of your process. We’ve got a lot of options! The important part is to make forward-thinking choices to save your future self, and even your current self, unnecessary headaches. |

Colour Accessibility |
Here’s a quote from Josef Albers:
In visual perception a colour is almost never seen as it really is[…] This fact makes colour the most relative medium in art.Josef Albers, Interaction of Color, 1963
Albers was a German abstract painter and teacher, and published a very famous course on colour theory in 1963. Colour is very relative — not just in the way that it appears differently across different devices due to screen quality and colour management, but it can also be seen differently by different people — something we really need to be more mindful of when designing.
What is colour blindness?
Colour blindness very rarely means that you can’t see any colour at all, or that people see things in greyscale. It’s actually a decreased ability to see colour, or a decreased ability to tell colours apart from one another.
How does it happen?
Inside the typical human retina, there are two types of receptor cells — rods and cones. Rods are the cells that allow us to see dark and light, and shape and movement. Cones are the cells that allow us to perceive colour. There are three types of cones, each responsible for absorbing blue, red, and green wavelengths in the spectrum.
Problems with colour vision occur when one or more of these types of cones are defective or absent entirely, and these problems can either be inherited through genetics, or acquired through trauma, exposure to ultraviolet light, degeneration with age, an effect of diabetes, or other factors.
Colour blindness is a sex-linked trait and it’s much more common in men than in women. The most common type of colour blindness is called deuteranomaly which occurs in 7% of males, but only 0.5% of females. That’s a pretty significant portion of the population if you really stop and think about it — we can’t ignore this demographic.
What does it look like?
People with the most common types of colour blindness, like protanopia and deuteranopia, have difficulty discriminating between red and green hues. There are also forms of colour blindness like tritanopia, which affects perception of blue and yellow hues. Below, you can see what a colour wheel might look like to these different people.
What can we do?
Here are some things you can do to make your websites and apps more accessible to people with all types of colour blindness.
Include colour names and show examples
One of the most common annoyances I’ve heard from people who are colour-blind is that they often have difficulty purchasing clothing and they will sometimes need to ask another person for a second opinion on what the colour of the clothing might actually be. While it’s easier to shop online than in a physical store, there are still accessibility issues to consider on shopping websites.
Let’s say you’ve got a website that sells T-shirts. If you only show a photo of the shirt, it may be impossible for a person to tell what colour the shirt really is. For clarification, be sure to reference the name of the colour in the description of the product.
United Pixelworkers does a great job of following this rule. The St. John’s T-shirt has a quirky palette inspired by the unofficial pink, white and green Newfoundland flag, and I can imagine many people not liking it.
Another common problem occurs when a colour filter has been added to a product search. Here’s an example from a clothing website with unlabelled colour swatches, and how that might look to someone with deuteranopia-type colour blindness.
The colour search filter below, from the H&M website, is much better since it uses names instead.
At first glance, Urban Outfitters also uses unlabelled colour swatches on product pages (below), but on closer inspection, the colour name is displayed on hover. This isn’t an ideal solution, because although it’ll work on a desktop browser, it won’t work on a touchscreen device where hovering isn’t an option.
Using overly fancy colour names, like the ones you might find labelling high-end interior paint can be just as confusing as not using a colour name at all. Names like grape instead of purple don’t really give the viewer any useful information about what the colour actually is on a colour wheel. Is grape supposed to be purple, or could it refer to red grapes or even green? Stick with hue names as much as possible.
Avoid colour-specific instructions
When designing forms, avoid labelling required fields only with coloured text. It’s safer to use a symbol cue like the asterisk which is colour-independent.
A similar example would be directing a user to click a green button to purchase a product. Label your buttons clearly and reference them in the site copy by function, not colour, to avoid confusion.
Don’t rely on colour coding
Designing accessible maps and infographics can be much more challenging.
Don’t rely on colour coding alone — try to use a combination of colour and texture or pattern, along with precise labels, and reflect this in the key or legend. Combine a blue background with a crosshatched pattern, or a pink background with a stippled dot — your users will always have two pieces of information to work with.
The map of the London subway system is an iconic image not just in London, but around the world. Unfortunately, it contains some colours that are indistinguishable from each other to a person with a vision problem. This is true not only for the London underground, but also for any other wayfinding system that relies on colour coding as the only key in a legend.
There are printable versions of the map available online in black and white, using patterns and shades of black and grey that are distinguishable, but the point is that there would be no need for such a map if it were designed with accessibility in mind from the beginning. And, if you’re a person who has a physical disability as well as a vision problem, the “Step-Free” guide map which shows stations is based on the original coloured map.
Provide alternatives and customization
While it’s best to consider these issues and design your app to be accessible by default, sometimes this might not be possible. Providing alternative styles or allowing users to edit their own colours is a feature to keep in mind.
The developers of the game Faster Than Light created an alternate colour-blind mode and asked for public feedback to make sure that it passed the test. Not much needed to be done, but you can see they added stripes to the red zones and changed some outlines to blue.
iChat is also a good example. Although by default it uses coloured bubbles to indicate a user’s status (available for chat, away or idle, or busy), included in the preferences is a “User Shapes to Indicate Status” option, which changes the shape of the standard circles to green circles, yellow triangles and red squares.
Pay attention to contrast
Colours that are similar in value but different in hue may be easy to distinguish between for a user with good vision, but a person who suffers from colour blindness may not be able to tell them apart at all. Proofing your work in greyscale is a quick way to tell if there’s enough contrast between the most important information in your design.
Check with a simulator
There are many tools out there for simulating different types of colour blindness, and it’s worth checking your design to catch any potential problems up front.
One is called Sim Daltonism and it’s available for Mac OS X. It’ll show a pop-up preview next to your cursor and you can choose which type of colour blindness you want to test from a drop-down menu.
You can also proof for the two most common types of colour blindness right in Photoshop or Illustrator (CS4 and later) while you’re designing.
The colour contrast check tool from designer and developer Jonathan Snook gives you the option to enter a colour code for a background, and a colour code for text, and it’ll tell you if the colour contrast ratio meets the Web Content Accessibility Guidelines 2.0. You can use the built-in sliders to adjust your colours until they meet the compliant contrast ratios. This is a great tool to test your palette before going live.
For live websites, you can use the accessibility tool called WAVE, which also has a contrast checker. It’s important to keep in mind, though, that while WAVE can identify contrast errors in text, other things can slip through, so a site that passes the test does not automatically mean it’s accessible in reality.
For example, the contrast checker here doesn’t notice that our red link in the introduction isn’t underlined, and therefore could blend into the surrounding paragraph text.
I know that once I started getting into the habit of checking my work in a simulator, I became more mindful of any potential problem areas and it was easier to avoid them up front. It’s also made me question everything I see around me and it sends red flags off in my head if I think it’s a serious colour blindness fail. Understanding that colour is relative in the planning stages and following these tips will help us make more accessible design for all. |

Fluent Design through Early Prototyping |
There’s a small problem with wireframes. They’re not good for showing the kind of interactions we now take for granted – transitions and animations on the web, in Android, iOS, and other platforms. There’s a belief that early prototyping requires a large amount of time and effort, and isn’t worth an early investment. But it’s not true!
It’s still normal to spend a significant proportion of time working in wireframes. Given that wireframes are high-level and don’t show much detail, it’s tempting to give up control and responsibility for things like transitions and other things sidelined as visual considerations. These things aren’t expressed well, and perhaps not expressed at all, in wireframes, yet they critically influence the quality of a product. Rapid prototyping early helps to bring sidelined but significant design considerations into focus.
Speaking fluent design
Fluency in a language means being able to speak it confidently and accurately. The Latin root means flow.
By design fluency, I mean using a set of skills in order to express or communicate an idea. Prototyping is a kind of fluency. It takes designers beyond the domain of grey and white boxes to consider all the elements that make up really good product design.
Designers shouldn’t be afraid of speaking fluent design. They should think thoroughly about product decisions beyond their immediate role — not for the sake of becoming some kind of power-hungry design demigod, but because it will lead to better, more carefully considered product design.
Wireframes are incomplete sentences
Wireframes, once they’ve served their purpose, are a kind of self-imposed restriction.
Mostly made out of grey and white boxes, they deliberately express the minimum. Important details — visuals, nuanced transitions, sounds — are missing. Their appearance bears little resemblance to the final thing. Responsibility for things that traditionally didn’t matter (or exist) is relinquished. Animations and transitions in particular are increasingly relevant to the mobile designer’s methods. And rather than being fanciful and superfluous visual additions to a product, they help to clarify designs and provide information about context.
Wireframes are useful in the early stages. As a designer trying to persuade stakeholders, clients, or peers, sometimes it will be in your interests to only tell half the story. They’re ideal for gauging whether a design is taking the right direction, and they’re the right medium for deciding core things, such as the overall structure and information architecture.
But spending a long time in wireframes means delaying details to a later stage in the project, or to the end, when the priority is shifted to getting designs out of the door. This leaves little time to test, finesse and perfect things which initially seemed to be less important. I think designers should move away from using wireframes as primary documentation once the design has reached a certain level of maturity.
A prototype is multiple complete sentences
Paragraphs, even.
Unlike a wireframe, a prototype is a persuasive storyteller. It can reveal the depth and range of design decisions, not just the layout, but also motion: animations and transitions. If it’s a super-high-fidelity prototype, it’s a perfect vessel for showing the visual design as well. It’s all of these things that contribute to the impression that a product is good… and useful, and engaging, and something you’d like to use.
A prototype is impressive. A good prototype can help to convince stakeholders and persuade clients. With a compelling demo, people can more easily imagine that this thing could actually exist. “Hey”, they’re thinking. “This might actually be pretty good!”
How to make a prototype in no time and with no effort
Now, it does take time and effort to make a prototype. However, good news! It used to require a lot more effort. There are tools that make prototyping much quicker and easier.
If you’re making a mobile prototype (this seems quite likely), you will want to test and show this on the actual device. This sounds like it could be a pain, but there are a few ways to do this that are quite easy.
Keynote, Apple’s presentation software, is an unlikely candidate for a prototyping tool, but surprisingly great and easy for creating prototypes with transitions that can be shown on different devices.
Keynote enables you to do a few useful, excellent things. You can make each screen in your design a slide, which can be linked together to allow you to click through the prototype. You can add customisable transitions between screens. If you want to show a panel that can slide open or closed on your iPad mockup, for example, transitions can also be added to individual elements on the screen. The design can be shown on tablet and mobile devices, and interacted with like it’s a real app. Another cool feature is that you can export the prototype as a video, which works as another effective format for demoing a design.
Overall, Keynote offers a very quick, lightweight way to prototype a design. Once you’ve learned the basics, it shouldn’t take longer than a few hours – at most – to put together a respectable clickable prototype with transitions.

This is a Quicktime movie exported from Keynote. This version is animated for demonstration purposes, but download the interactive original and you can click the screen to move through the prototype. It demonstrates the basic interactivity of an iPhone app. This anonymised example was used on a project at Fjord to create a master example of an app’s transitions.
Prototyping drawbacks, and perceived drawbacks
If prototyping is so great, then why do we leave it to the end, or not bother with it at all? There are multiple misconceptions about prototyping: they’re too difficult to make; they take too much time; or they’re inaccurate (and dangerous) documentation.
A prototype is a preliminary model. There should always be a disclaimer that it’s not the real thing to avoid setting up false expectations.
A prototype doesn’t have to be the main deliverable. It can be a key one that’s supported by visual and interaction specifications. And a prototype is a lightweight means of managing and reflecting changes and requirements in a project.
An actual drawback of prototyping is that to make one too early could mean being gung-ho with what you thought a client or stakeholder wanted, and delivering something inappropriate. To avoid this, communicate, iterate, and keep things simple until you’re confident that the client or other stakeholders are happy with your chosen direction.
The key throughout any design project is iteration. Designers build iterative models, starting simple and becoming increasingly sophisticated. It’s a process of iterative craft and evolution. There’s no perfect methodology, no magic recipe to follow.
What to do next
Make a prototype! It’s the perfect way to impress your friends.
It can help to advance a brilliant idea with a fraction of the effort of complete development. Sketches and wireframes are perfect early on in a project, but once they’ve served their purpose, prototypes enable the design to advance, and push thinking towards clarifying other important details including transitions.
For Keynote tutorials, Keynotopia is a great resource. Axure is standard and popular prototyping software many UX designers will already be familiar with; it’s possible to create transitions in Axure. POP is an iPhone app that allows you to design apps on paper, take photos with your phone, and turn them into interactive prototypes. Ratchet is an elegant iPhone prototyping tool aimed at web developers.
There are perhaps hundreds of different prototyping tools and methods. My final advice is not to get bogged down in (or limited by) any particular tool, but to remember you’re making quick and iterative models. Experiment and play!
Prototyping will push you and your designs to a scary place without limitations. No more grey and white boxes, just possibilities! |

Responsive Images: What We Thought We Needed |
If you were to read a web designer’s Christmas wish list, it would likely include a solution for displaying images responsively. For those concerned about users downloading unnecessary image data, or serving images that look blurry on high resolution displays, finding a solution has become a frustrating quest.
Having experimented with complex and sometimes devilish hacks, consensus is forming around defining new standards that could solve this problem. Two approaches have emerged.
The <picture> element markup pattern was proposed by Mat Marquis and is now being developed by the Responsive Images Community Group. By providing a means of declaring multiple sources, authors could use media queries to control which version of an image is displayed and under what conditions:
<picture width="500" height="500">
<source media="(min-width: 45em)" src="large.jpg">
<source media="(min-width: 18em)" src="med.jpg">
<source src="small.jpg">
<img src="small.jpg" alt="">
<p>Accessible text</p>
</picture>
A second proposal put forward by Apple, the srcset attribute, uses a more concise syntax intended for use with the <img> element, although it could be compatible with the <picture> element too. This would allow authors to provide a set of images, but with the decision on which to use left to the browser:
<img src="fallback.jpg" alt="" srcset="small.jpg 640w 1x, small-hd.jpg 640w 2x, med.jpg 1x, med-hd.jpg 2x ">
Enter Scrooge
Men’s courses will foreshadow certain ends, to which, if persevered in, they must lead.
Ebenezer Scrooge
Given the complexity of this issue, there’s a heated debate about which is the best option. Yet code belies a certain truth. That both feature verbose and opaque syntax, I’m not sure either should find its way into the browser – especially as alternative approaches have yet to be fully explored.
So, as if to dampen the festive cheer, here are five reasons why I believe both proposals are largely redundant.
1. We need better formats, not more markup
As we move away from designs defined with fixed pixel values, bitmap images look increasingly unsuitable. While simple images and iconography can use scalable vector formats like SVG, for detailed photographic imagery, raster formats like GIF, PNG and JPEG remain the only suitable option.
There is scope within current formats to account for varying bandwidth but this requires cooperation from browser vendors. Newer formats like JPEG2000 and WebP generate higher quality images with smaller file sizes, but aren’t widely supported.
While it’s tempting to try to solve this issue by inventing new markup, the crux of it remains at the file level.
Daan Jobsis’s experimentation with image compression strengthens this argument. He discovered that by increasing the dimensions of a JPEG image while simultaneously reducing its quality, a smaller files could be produced, with the resulting image looking just as good on both standard and high-resolution displays.
This may be a hack in lieu of a more permanent solution, but it’s applied in the right place. Easy to accomplish with existing tools and without compatibility issues, it has few downsides. Further experimentation in this area should be encouraged, with standardisation efforts more helpful if focused on developing new image formats or, preferably, extending existing ones.
2. Art direction doesn’t belong in markup
A desired benefit of the <picture> markup pattern is to allow for greater art direction. For example, rather than scaling down images on smaller displays to the point that their content is hard to discern, we could present closer crops instead:
This can be achieved with CSS of course, although with a download penalty for those parts of an image not shown. This point may be negligible, however, since in the context of adaptable layouts, these hidden areas may end up being revealed anyway.
Art direction concerns design, not content. If we wish to maintain a separation of concerns, including presentation within our markup seems misguided.
3. The size of a display has little relation to the size of an image
By using media queries, the <picture> element allows authors to choose which characteristics of the screen or viewport to query for different images to be displayed.
In developing sites at Clearleft, we have noticed that the viewport is essentially arbitrary, with the size of an image’s containing element more important. For example, look at how this grid of images may adapt at different viewport widths:
As we build more modular systems, components need to be adaptable in and of themselves. There is a case to be made for developing more contextual methods of querying, rather than those based on attributes of the display.
4. We haven’t lived with the problem long enough
A key strength of the web is that the underlying platform can be continually iterated. This can also be problematic if snap judgements are made about what constitutes an improvement.
The early history of the web is littered with such examples, be it the perceived need for blinking text or inline typographic styling. To build a platform for the future, additions to it should be carefully considered. And if we want more consistent support across browsers, burdening vendors with an ever increasing list of features seems counterproductive.
Only once the need for a new feature is sufficiently proven, should we look to standardise it. Before we could declare hover effects, rounded corners and typographic styling in CSS, we used JavaScript as a polyfill. Sure, doing so was painful, but use cases were fully explored, and the CSS specification better reflected the needs of authors.
5. Images and the web aesthetic
The srcset proposal has emerged from a company that markets its phones as being able to browse the real – yet squashed down, tapped and zoomable – web. Perhaps Apple should make its own website responsive before suggesting how the rest of us should do so.
Converserly, while the <picture> proposal has the backing of a few respected developers and designers, it was born out of the work Mat Marquis and Filament Group did for the Boston Globe. As the first large-scale responsive design, this was a landmark project that ignited the responsive web design movement and proved its worth. But it was the first.
Its design shares a vernacular to that of contemporary newspaper websites, with a columnar, image-laden and densely packed layout. Compared to more recent examples – Quartz, The Next Web and the New York Times Skimmer – it feels out of step with the future direction of news sites. In seeking out a truer aesthetic for the web in which software interfaces have greater influence, we might discover that the need for responsive images isn’t as great as originally thought.
Building for the future
With responsive design, we’ve accepted the idea that a fully fluid layout, rather than a set of fixed layouts, is best suited to the web’s unpredictable nature. Current responsive image proposals are antithetical to this approach.
We need solutions that lack complexity, are device-agnostic and work within existing workflows. Any proposal that requires different versions of the same image to be created, is likely to have to acquiesce under the pressure of reality.
While it’s easy to get distracted about the size and quality of an image, and how we might choose to serve it, often the simplest solution is not to include it at all. After years of gluttonous design practice, in which fast connections and expansive display sizes were an accepted norm, we have got use to filling pages with needless images and countless items of page furniture.
To design more adaptable experiences, the presence of every element needs to be questioned, for its existence requires additional data to be downloaded or futher complexity within a design system. Conditional loading techniques mean that the inclusion of images is no longer a binary choice, but can instead appear in a progressively enhanced manner.
So here is my proposal. Instead of spending the next year worrying about responsive images, let’s embrace the constraints of the medium, and seek out new solutions that can work within them. |

HTML5 Video Bumpers |
Video is a bigger part of the web experience than ever before. With native browser support for HTML5 video elements freeing us from the tyranny of plugins, and the availability of faster internet connections to the workplace, home and mobile networks, it’s now pretty straightforward to publish video in a way that can be consumed in all sorts of ways on all sorts of different web devices.
I recently worked on a project where the client had shot some dedicated video shorts to publish on their site. They also had some five-second motion graphics produced to top and tail the videos with context and branding. This pretty common requirement is a great idea on the web, where a user might land at your video having followed a link and be viewing a page without much context.
Known as bumpers, these short introduction clips help brand a video and make it look a lot more professional.
Adding bumpers to a video
The simplest way to add bumpers to a video would be to edit them on to the start and end of the video file itself. Cooking the bumpers into the video file is easy, but should you ever want to update them it can become a real headache. If the branding needs updating, for example, you’d need to re-edit and re-encode all your videos. Not a fun task.
What if the bumpers could be added dynamically? That would enable you to use the same bumper for multiple videos (decreasing download time for users who might watch more than one) and to update the bumpers whenever you wanted. You could change them seasonally, update them for special promotions, run different advertising slots, perform multivariate testing, or even target different bumpers to different users.
The trade-off, of course, is that if you dynamically add your bumpers, there’s a chance that a user in a given circumstance might not see the bumper. For example, if the main video feature was uploaded to YouTube, you’d have no way to control the playback. As always, you need to weigh up the pros and cons and make your choice.
HTML5 bumpers
If you wanted to dynamically add bumpers to your HTML5 video, how would you go about it? That was the question I found myself needing to answer for this particular client project.
My initial thought was to treat it just like an image slideshow. If I were building a slideshow that moved between images, I’d use CSS absolute positioning with z-index to stack the images up on top of each other in a pile, with the first image on top. To transition to the second image, I’d use JavaScript to fade the top image out, revealing the second image beneath it.
Now that video is just a native object in the DOM, just like an image, why not do the same? Stack the videos up with the opening bumper on top, listen for the video’s onended event, and fade it out to reveal the main feature behind. Good idea, right?
Wrong
Remember that this is the web. It’s never going to be that easy. The problem here is that many non-desktop devices use native, dedicated video players. Think about watching a video on a mobile phone – when you play the video, the phone often goes full-screen in its native player, leaving the web page behind. There’s no opportunity to fade or switch z-index, as the video isn’t being viewed in the page. Your page is left powerless. Powerless!
So what can we do? What can we control?
Those of us with particularly long memories might recall a time before CSS, when we’d have to use JavaScript to perform image rollovers. As CSS background images weren’t a practical reality, we would use lots of <img> elements, and perform a rollover by modifying the src attribute of the image.
Turns out, this old trick of modifying the source can help us out with video, too. In most cases, modifying the src attribute of a <video> element, or perhaps more likely the src attribute of a source element, will swap from one video to another.
Swappin’ it
Let’s take a deliberately simple example of a super-basic video tag:
<video src="mycat.webm" controls>no fallback coz i is lame, innit.</video>
We could very simply write a script to find all video tags and give them a new src to show our bumper.
<script>
var videos, i, l;
videos = document.getElementsByTagName('video');
for(i=0, l=videos.length; i<l; i++) {
videos[i].setAttribute('src', 'bumper-in.webm');
}
</script>
View the example in a browser with WebM support. You’ll see that the video is swapped out for the opening bumper. Great!
Beefing it up
Of course, we can’t just publish video in one format. In practical use, you need a <video> element with multiple <source> elements containing your different source formats.
<video controls>
<source src="mycat.mp4" type="video/mp4" />
<source src="mycat.webm" type="video/webm" />
<source src="mycat.ogv" type="video/ogg" />
</video>
This time, our script needs to loop through the sources, not the videos. We’ll use a regular expression replacement to swap out the file name while maintaining the correct file extension.
<script>
var sources, i, l, orig;
sources = document.getElementsByTagName('source');
for(i=0, l=sources.length; i<l; i++) {
orig = sources[i].getAttribute('src');
sources[i].setAttribute('src', orig.replace(/(w+).(w+)/, 'bumper-in.$2'));
// reload the video
sources[i].parentNode.load();
}
</script>
The difference this time is that when changing the src of a <source> we need to call the .load() method on the video to get it to acknowledge the change.
See the code in action, this time in a wider range of browsers.
But, my video!
I guess we should get the original video playing again. Keeping the same markup, we need to modify the script to do two things:
Store the original src in a data- attribute so we can access it later
Add an event listener so we can detect the end of the bumper playing, and load the original video back in
As we need to loop through the videos this time to add the event listener, I’ve moved the .load() call into that loop. It’s a bit more efficient to call it only once after modifying all the video’s sources.
<script>
var videos, sources, i, l, orig;
sources = document.getElementsByTagName('source');
for(i=0, l=sources.length; i<l; i++) {
orig = sources[i].getAttribute('src');
sources[i].setAttribute('data-orig', orig);
sources[i].setAttribute('src', orig.replace(/(w+).(w+)/, 'bumper-in.$2'));
}
videos = document.getElementsByTagName('video');
for(i=0, l=videos.length; i<l; i++) {
videos[i].load();
videos[i].addEventListener('ended', function(){
sources = this.getElementsByTagName('source');
for(i=0, l=sources.length; i<l; i++) {
orig = sources[i].getAttribute('data-orig');
if (orig) {
sources[i].setAttribute('src', orig);
}
sources[i].setAttribute('data-orig','');
}
this.load();
this.play();
});
}
</script>
Again, view the example to see the bumper play, followed by our spectacular main feature. (That’s my cat, Widget. His interests include sleeping and internet marketing.)
Tidying things up
The final thing to do is add our closing bumper after the main video has played. This involves the following changes:
We need to keep track of whether the src has been changed, so we only play the video if it’s changed. I’ve added the modified variable to track this, and it stops us getting into a situation where the video just loops forever.
Add an else to the event listener, for when the orig is false (so the main feature has been playing) to load in the end bumper. We also check that we’re not already playing the end bumper. Because looping.
<script>
var videos, sources, i, l, orig, current, modified;
sources = document.getElementsByTagName('source');
for(i=0, l=sources.length; i<l; i++) {
orig = sources[i].getAttribute('src');
sources[i].setAttribute('data-orig', orig);
sources[i].setAttribute('src', orig.replace(/(w+).(w+)/, 'bumper-in.$2'));
}
videos = document.getElementsByTagName('video');
for(i=0, l=videos.length; i<l; i++) {
videos[i].load();
modified = false;
videos[i].addEventListener('ended', function(){
sources = this.getElementsByTagName('source');
for(i=0, l=sources.length; i<l; i++) {
orig = sources[i].getAttribute('data-orig');
if (orig) {
sources[i].setAttribute('src', orig);
modified = true;
}else{
current = sources[i].getAttribute('src');
if (current.indexOf('bumper-out')==-1) {
sources[i].setAttribute('src', current.replace(/([w]+).(w+)/, 'bumper-out.$2'));
modified = true;
}else{
this.pause();
modified = false;
}
}
sources[i].setAttribute('data-orig','');
}
if (modified) {
this.load();
this.play();
}
});
}
</script>
Yo ho ho, that’s a lot of JavaScript. See it in action – you should get a bumper, the cat video, and an end bumper.
Of course, this code works fine for demonstrating the principle, but it’s very procedural. Nothing wrong with that, but to do something similar in production, you’d probably want to make the code more modular to ease maintainability. Besides, you may want to use a framework, rather than basic JavaScript.
The end credits
One really important principle here is that of progressive enhancement. If the browser doesn’t support JavaScript, the user won’t see your bumper, but they will get the main video. If the browser supports JavaScript but doesn’t allow you to modify the src (as was the case with older versions of iOS), the user won’t see your bumper, but they will get the main video.
If a search engine or social media bot grabs your page and looks for content, they won’t see your bumper, but they will get the main video – which is absolutely what you want.
This means that if the bumper is absolutely crucial, you may still need to cook it into the video. However, for many applications, running it dynamically can work quite well.
As always, it comes down to three things:
Measure your audience: know how people access your site
Test the solution: make sure it works for your audience
Plan for failure: it’s the web and that’s how things work ‘round these parts
But most of all play around with it, have fun and build something awesome. |

Science! |
Sometimes we want to capture people’s attention at a glance to communicate something fast. At other times we want to have the interface fade away into the background, letting people paint pictures in their minds with our words (if you’ll forgive a little flowery festive flourish).
I tend to distinguish between these two broad objectives as designing for impact on the one hand, and designing for immersion on the other. What defines them is interruption. Impact needs an attention-grabbing interruption. Immersion requires us to remove interruption from the interface. Careful design deliberately interrupts but doesn’t accidentally disrupt. If that seems to make sense to you, then you’ll find the following snippets of science as useful as I did.
Saccades and fixations
As you’re reading this your eyes are skipping along the lines in tiny jumps. During each jump everything is blurred. Each jump ends in a small pause so your brain can take a snapshot of the letters. It arranges them into words, and then parses out the meaning — fast — in around a quarter of a second.
The jumps are called saccades. The pauses are called fixations. Sometimes we take regressive saccades, skipping back to reread. There’s a simple example in the excellent little book, Detail in Typography, by Jost Hochuli.
If you want to explore the science of reading in much more depth, I recommend the excellent paper, “The Science of Word Recognition”, by Dr Kevin Larson of Microsoft.
To design for legibility and readability is to design for saccades and fixations. It’s the craft of making it easy for people’s brains to extract meaning, using techniques like good contrast, font size, spacing and structure, and only interrupting the reading experience deliberately.
Scan paths
At some point when visiting 24 ways you probably scanned the screen to get orientated. The journey your eyes took is known as a scan path. Scan paths are made up of saccades and fixations. Right now you’re following a scan path as you read, along one line, and down to the next. This is a map of the scan paths found by Olivier Le Meur from observing people looking at Rembrandt’s Leçon d’anatomie:
For websites, the scan path is a little different. This is an aggregate scan path of Google from LC Technologies:
The average shape of a website scan path becomes clearer in this average scan path taken by forty-six people during research by the Poynter Institute, the Estlow Center for Journalism & New Media, and Eyetools:
Just like when we read text arranged left to right in a vertical column, scan paths follow a roughly Z-shaped pattern from the top left to bottom right. Sometimes we skip back to reread a word or sentence, or glance again at a specific element, but the Z-shaped scan path persists.
Designing for scan paths is to organise content to help people move through an interface to get orientated, and to read.
The elements that are important enough to need impact must interrupt the scan path and clearly call attention to themselves. However, they don’t always need to clip people round the ear from multiple directions at once to get attention. It helps to list elements by importance. That gives us an interruption hierarchy to work with. Elements can then interrupt the design with degrees of contrast to the rest of the content using either positioning, treatment, or both. Ta-da! Impact achieved, but gently. No clips round the ear required.
Swinging mood
Human beings are resilient. Among the immersion and occasional interruptions, we even like a little disruption, especially if it’s absurd and funny. The Ling’s Cars website proves it. In fact, we’re so resilient that we can work around all kinds of mayhem to get a seemingly simple task done.
In one study, “The Aesthetics of Reading” (PDF, 480Kb), Dr Kevin Larson of Microsoft and Dr Rosalind Picard of MIT explored the effect of good typography on mood. Two versions of the New Yorker ePeriodical were created. One was typeset well and the other poorly.
They engaged twenty volunteers — half male, half female — and showed the good version to half of the participants. The other half saw the poor version.
The good doctors found that, “there are important differences between good and poor typography that appear to have little effect on common performance measures such as reading speed and comprehension.” In short, good typography didn’t help people read faster or comprehend better.
Oh. On the face of it that seems to invalidate what we designers do. Hold your horses, though! They also found that “the participants who received the good typography performed better on relative subjective duration and on certain cognitive tasks”, and that “good typography induces a good mood.”
This means that even though there were no actual differences in reading speed and comprehension, the people who read the version with good typography thought that it took less time to read, and were induced into a good mood by doing so. Not only that, but by being in a good mood, people were more capable of completing creative tasks faster.
That was a revelation to me. It means that the study showed there is a positive, measurable, emotional and perceptual benefit to good typography and design. To paraphrase: time and tasks fly when you’re having fun!

So, among all my talk of saccades, fixations, scan paths and typesetting, there is science, and the science helps us qualify our design decisions when we need to, and do our jobs better. The science helps us understand how people will interact with our work, and what the actual benefits are for them, and the products or organisations we serve. Good design equals a subjectively quicker experience, a good mood, objectively faster completion of tasks, and happiness for everyone. Thank you, science! |

Being Prepared To Contribute |
“You’ll figure it out.” The advice my dad gives has always been the same, whether addressing my grade school homework or paying bills after college. If I was looking for a shortcut, my dad wasn’t going to be the one to provide it.
When I was a kid it infuriated the hell out of me, but what I then perceived to be a lack of understanding turned out to be a keystone in my upbringing. As an adult, I realize the value in not receiving outright solutions, but being forced to figure things out.
Even today, when presented with a roadblock while building for the web, I am temped to get by with the help of the latest grid system, framework, polyfill, or plugin. In and of themselves these resources are harmless, but before I can drop them in, those damn words still echo in the back of my mind: “You’ll figure it out.”
I know that if I blindly implement these tools as drag and drop solutions I fail to understand the intricacies behind how and why they were built; repeatedly using them as shortcuts handicaps my skill set. When I solely rely on the tools of others, my work is at their mercy, leaving me less creative and resourceful, and, thus, less able to contribute to the advancement of our industry and community.
One of my favorite things about this community is how generous and collaborative it can be. I’ve loved seeing FitVids used all over the web and regularly improved upon at Github. I bet we can all think of a time where implementing a shared resource has benefitted our own work and sanity. Because these resources are so valuable, it’s important that we continue to be a part of the conversation in order to further develop solutions and ideas. It’s easy to assume there’s someone smarter or more up-to-date in any one area, but with a degree of understanding and perspective, we can all participate.
This open form of collaboration is in our web DNA. After all, its primary purpose was to promote the exchange and development of new ideas.
Tim Berners-Lee proposed a global hypertext project, to be known as the World Wide Web. Based on the earlier “Enquire” work, it was designed to allow people to work together by combining their knowledge in a web of hypertext documents.
I’m delighted to find that this spirit of collaborative ingenuity is alive and well on the web today. Take the story of Off Canvas as an example. I was at an ATX Dribbble meet up where I met Jason Weaver and chatted to him about his recent work on the responsive layout prototype, Off Canvas. Jason said he came across a post by Luke Wroblewski outlining the idea and saw this:
If anyone is interested in building a complete example of this approach using responsive Web design techniques, let me know!
From there Luke recounts:
We went back and forth on email, with me laying out ideas and Jason doing all the hard work to see if they can be done and improving them bit by bit! Once we got to something we both liked, I wrote up an article explaining things and he hosted the examples.
Luke took the time to clearly outline and diagram his ideas, and Jason responded with a solid proof of concept that has evolved into a tool we all have at our disposal. Victory!
I have also benefitted from comrades who have taken an idea of mine into development. After blogging about some concerns in regards to maintaining hierarchy as media queries are used to shift layouts, Jordan Moore rebounded with some responsive demos where he used flexbox to (re)order content as viewport sizing changes.
Similar stories can be found behind the development of things like FitVids, FitText, and Molten Leading. I love this pattern of collaboration because it involves a fairly specific process:
Initial idea or prototype is outlined or built, then shared
Discuss
Someone develops or improves it, then shares it
Discuss
Someone else develops or improves it, then shares it.
Infinity.
This is what the web looks like when we build it together, and I’d argue that steps 2+ are absolutely crucial. A web where everyone develops their own ideas and tools independent of one another is like a room full of people talking and no one listening.
The pattern itself mimics a literal web structure, and ideally we’d be able to follow a strand from one idea to the next and so on.
Blessed are the curators
Sometimes those lines aren’t easy to find or follow. Thankfully, there are people who painstakingly log each experiment and index much of what’s out there. Chris Coyier does this with CSS in general, and Brad Frost is doing this for responsive and multi-device design with his Pattern Library. Seriously, take a look at this page and imagine what it would take to find, track and organize the progression of each of these resources yourself. I’d argue that ongoing collections like these are more valuable than the sum of their parts when they are updated regularly as opposed to a top ten tips blog post format.
Here’s my soapbox
Here are a few things I appreciate about how things are shared and contributed online. And yes, I could do way better at all of them myself.
Concise write-ups: honor others’ time by getting to the point. Not every idea or solution needs two thousand words to convey fully. I love long-form posts, but there’s a time and a place for them.
Visual aids: if a quick illustration, screenshot, or graphic helps illustrate your point or problem, yes please.
By the way, Luke Wroblewski rules the school on both of these.
Demo it: host it yourself, or put it on CodePen or JS Bin for others to see.
Put it on Github: share and improve with the rest of the community. Consider, however, that because someone puts something on Github doesn’t mean they’re forever bound to provide support or instruction.
This isn’t a call for everyone to learn everything all the time, but if you’re curious or interested in something, skip the shortcut and get your hands dirty: sketch, prototype, question, debate, fork, and share. Figuring these things out on our own makes us valuable contributors to the web – the thing that ultimately we’re all trying to figure out together. |

Cut Copy Paste |
Long before I got into this design thing, I was heavily into making my own music inspired by the likes of Coldcut and Steinski. I would scour local second-hand record shops in search of obscure beats, loops and bits of dialogue in the hope of finding that killer sample I could then splice together with other things to make a huge hit that everyone would love. While it did eventually lead to a record contract and getting to release a few 12″ singles, ultimately I knew I’d have to look for something else to pay the bills.
I may not make my own records any more, but the approach I took back then – finding (even stealing) things, cutting and pasting them into interesting combinations – is still at the centre of how I work, only these days it’s pretty much bits of code rather than bits of vinyl. Over the years I’ve stored these little bits of code (some I’ve found, some I’ve created myself) in Evernote, ready to be dialled up whenever I need them.
So when Drew got in touch and asked if I’d like to do something for this year’s 24 ways I thought it might be kind of cool to share with you a few of these snippets that I find really useful. Think of these as a kind of coding mix tape; but remember – don’t just copy as is: play around, combine and remix them into other wonderful things.
Some of this stuff is dirty; some of it will make hardcore programmers feel ill. For those people, remember this – while you were complaining about the syntax, I made something.
Create unique colours
Let’s start right away with something I stole. Well, actually it was given away at the time by Matt Biddulph who was then at Dopplr before Nokia destroyed it. Imagine you have thousands of words and you want to assign each one a unique colour. Well, Matt came up with a crazily simple but effective way to do that using an MD5 hash. Just encode said word using an MD5 hash, then take the first six characters of the string you get back to create a hexadecimal colour representation.
I can’t guarantee that it will be a harmonious colour palette, but it’s still really useful. The thing I love the most about this technique is the left-field thinking of using an encryption system to create colours! Here’s an example using JavaScript:
// requires the MD5 library available at http://pajhome.org.uk/crypt/md5
function MD5Hex(str){
result = MD5.hex(str).substring(0, 6);
return result;
}
Make something breathe using a sine wave
I never paid attention in school, especially during double maths. As a matter of fact, the only time I received corporal punishment – several strokes of the ruler – was in maths class. Anyway, if they had shown me then how beautiful mathematics actually is, I might have paid more attention. Here’s a little example of how a sine wave can be used to make something appear to breathe.
I recently used this on an Arduino project where an LED ring surrounding a button would gently breathe. Because of that it felt much more inviting. I love mathematics.
for(int i = 0; i<360; i++){
float rad = DEG_TO_RAD * i;
int sinOut = constrain((sin(rad) * 128) + 128, 0, 255);
analogWrite(LED, sinOut);
delay(10);
}
Snap position to grid
This is so elegant I love it, and it was shown to me by Gary Burgess, or Boom Boom as myself and others like to call him. It snaps a position, in this case the X-position, to a grid. Just define your grid size (say, twenty pixels) and you’re good.
snappedXpos = floor( xPos / gridSize) * gridSize;
Calculate the distance between two objects
For me, interaction design is about the relationship between two objects: you and another object; you and another person; or simply one object to another. How close these two things are to each other can be a handy thing to know, allowing you to react to that information within your design. Here’s how to calculate the distance between two objects in a 2-D plane:
deltaX = round(p2.x-p1.x);
deltaY = round(p2.y-p1.y);
diff = round(sqrt((deltaX*deltaX)+(deltaY*deltaY)));
Find the X- and Y-position between two objects
What if you have two objects and you want to place something in-between them? A little bit of interruption and disruption can be a good thing. This small piece of code will allow you to place an object in-between two other objects:
// set the position: 0.5 = half-way
float position = 0.5;
float x = x1 + (x2 - x1) *position;
float y = y1 + (y2 - y1) *position;
Distribute objects equally around a circle
More fun with maths, this time adding cosine to our friend sine. Let’s say you want to create a circular navigation of arbitrary elements (yeah, Jakob, you heard), or you want to place images around a circle. Well, this piece of code will do just that. You can adjust the size of the circle by changing the distance variable and alter the number of objects with the numberOfObjects variable. Example below is for use in Processing.
// Example for Processing available for free download at processing.org
void setup() {
size(800,800);
int numberOfObjects = 12;
int distance = 100;
float inc = (TWO_PI)/numberOfObjects;
float x,y;
float a = 0;
for (int i=0; i < numberOfObjects; i++) {
x = (width/2) + sin(a)*distance;
y = (height/2) + cos(a)*distance;
ellipse(x,y,10,10);
a += inc;
}
}
Use modulus to make a grid
The modulus operator, represented by %, returns the remainder of a division. Fallen into a coma yet? Hold on a minute – this seemingly simple function is very powerful in lots of ways. At a simple level, you can use it to determine if a number is odd or even, great for creating alternate row colours in a table for instance:
boolean checkForEven(numberToCheck) {
if (numberToCheck % 2 == 0)
return true;
} else {
return false;
}
}
That’s all well and good, but here’s a use of modulus that might very well blow your mind. Construct a grid with only a few lines of code. Again the example is in Processing but can easily be ported to any other language.
void setup() {
size(600,600);
int numItems = 120;
int numOfColumns = 12;
int xSpacing = 40;
int ySpacing = 40;
int totalWidth = xSpacing*numOfColumns;
for (int i=0; i < numItems; i++) {
ellipse(floor((i*xSpacing)%totalWidth),floor((i*xSpacing)/totalWidth)*ySpacing,10,10);
}
}
Not all the bits of code I keep around are for actual graphical output. I also have things that are very utilitarian, but which I still consider part of the design process. Here’s a couple of things that I’ve found really handy lately in my design workflow. They may be a little specific, but I hope they demonstrate that it’s not about working harder, it’s about working smarter.
Merge CSV files into one file
Recently, I’ve had to work with huge – about 1GB – CSV text files that I then needed to combine into one master CSV file so I could then process the data. Opening up each text file and then copying and pasting just seemed really dumb, not to mention slow, so I thought there must be a better way. After some Googling I found this command line script that would combine .txt files into one file and add a new line after each:
awk 1 *.txt > finalfile.txt
But that wasn’t what I was ideally after. I wanted to merge the CSV files, keeping the first row of the first file (the column headings) and then ignore the first row of subsequent files. Sure enough I found the answer after some Googling and it worked like a charm. Apologies to the original author but I can’t remember where I found it, but you, sir or madam, are awesome. Save this as a shell script:
FIRST=
for FILE in *.csv
do
exec 5<"$FILE" # Open file
read LINE <&5 # Read first line
[ -z "$FIRST" ] && echo "$LINE" # Print it only from first file
FIRST="no"
cat <&5 # Print the rest directly to standard output
exec 5<&- # Close file
# Redirect stdout for this section into file.out
done > file.out
Create a symbolic link to another file or folder
Oftentimes, I’ll find myself hunting through a load of directories to load a file to be processed, like a CSV file. Use a symbolic link (in the Terminal) to place a link on your desktop or wherever is most convenient and it’ll save you loads of time. Especially great if you’re going through a Java file dialogue box in Processing or something that doesn’t allow the normal Mac dialog box or aliases.
cd /DirectoryYouWantShortcutToLiveIn
ln -s /Directory/You/Want/ShortcutTo/ TheShortcut
You can do it, in the mix
I hope you’ve found some of the above useful and that they’ve inspired a few ideas here and there. Feel free to tell me better ways of doing things or offer up any other handy pieces of code. Most of all though, collect, remix and combine the things you discover to make lovely new things. |

Responsive Responsive Design |
Now more than ever, we’re designing work meant to be viewed along a gradient of different experiences. Responsive web design offers us a way forward, finally allowing us to “design for the ebb and flow of things.”
With those two sentences, Ethan closed the article that introduced the web to responsive design. Since then, responsive design has taken the web by storm. Seemingly every day, some company is touting their new responsive redesign. Large brands such as Microsoft, Time and Disney are getting in on the action, blowing away the once common criticism that responsive design was a technique only fit for small blogs.
Certainly, this is a good thing. As Ethan and John Allsopp before him, were right to point out, the inherent flexibility of the web is a feature, not a bug. The web’s unique ability to be consumed and interacted with on any number of devices, with any number of input methods is something to be embraced.
But there’s one part of the web’s inherent flexibility that seems to be increasingly overlooked: the ability for the web to be interacted with on any number of networks, with a gradient of bandwidth constraints and latency costs, on devices with varying degrees of hardware power.
A few months back, Stephanie Rieger tweeted
“Shoot me now…responsive design has seemingly become confused with an opportunity to reduce performance rather than improve it.”
I would love to disagree, but unfortunately the evidence is damning. Consider the size and number of requests for four highly touted responsive sites that were launched this year:
74 requests, 1,511kb
114 requests, 1,200kb
99 requests, 1,298kb
105 requests, 5,942kb
And those numbers were for the small screen versions of each site!
These sites were praised for their visual design and responsive nature, and rightfully so. They’re very easy on the eyes and a lot of thought went into their appearance. But the numbers above tell an inconvenient truth: for all the time spent ensuring the visual design was airtight, seemingly very little (if any) attention was given to their performance.
It would be one thing if these were the exceptions, but unfortunately they’re not. Guy Podjarny, who has done a lot of research around responsive performance, discovered that 86% of the responsive sites he tested were either the same size or larger on the small screen as they were on the desktop.
The reality is that high performance should be a requirement on any web project, not an afterthought. Poor performance has been tied to a decrease in revenue, traffic, conversions, and overall user satisfaction. Case study after case study shows that improving performance, even marginally, will impact the bottom line. The situation is no different on mobile where 71% of people say they expect sites to load as quickly or faster on their phone when compared to the desktop.
The bottom line: performance is a fundamental component of the user experience.
So, given it’s extreme importance in the success of any web project, why is it that we’re seeing so many bloated responsive sites?
First, I adamantly disagree with the belief that poor performance is inherent to responsive design. That’s not a rule – it’s a cop-out. It’s an example of blaming the technique when we should be blaming the implementation. This argument also falls flat because it ignores the fact that the trend of fat sites is increasing on the web in general. While some responsive sites are the worst offenders, it’s hardly an issue resigned to one technique.
To fix the issue, we need to stop making excuses and start making improvements instead. Here, then, are some things we can do to start improving the state of responsive performance, and performance in general, right now.
Create a culture of performance
If you understand just how important performance is to the success of a project, the natural next step is to start creating a culture where high performance is a key consideration.
One of the things you can do is set a baseline. Determine the maximum size and number of requests you are going to allow, and don’t let a page go live if either of those numbers is exceeded. The BBC does this with its responsive mobile site.
A variation of that, which Steve Souders discussed in a recent podcast is to create a performance budget based on those numbers. Once you have that baseline set, if someone comes along and wants to add a something to the page, they have to make sure the page remains under budget. If it exceeds the budget, you have three options:
Optimize an existing feature or asset on the page
Remove an existing feature or asset from the page
Don’t add the new feature or asset
The idea here is that you make performance part of the process instead of something that may or may not get tacked on at the end.
Embrace the pain
This troubling trend of web bloat can be blamed in part on the lack of pain associated with poor performance. Most of us work on high-speed connections with low latency. When we fire up a 4Mb site, it doesn’t feel so bad.
When I tested the previously mentioned 5,942kb site on a 3G network, it took over 93 seconds to load. A minute and a half just staring at a white screen. Had anyone working on that project experienced that, you can bet the site wouldn’t have launched in that state.
Don’t just crunch numbers. Fire up your site on a slower network and see what it feels like to wait. If you don’t have access to a slow network, simulate one using a tool like Slowy, Throttle or the Network Conditioner found in Mac OS X 10.7.
Watch for low-hanging fruit
There are a bunch of general performance improvements that apply to any site (responsive or not) but often aren’t made. A great starting point is to refer to Yahoo!‘s list of rules.
Some of this might sound complicated or intimidating, but it doesn’t have to be. You can grab an .htaccess file from HTML 5 Boilerplate or use Sergey Chernyshev’s drop-in .htaccess file. You can use tools like SpriteMe to simplify the creation of sprites, and ImageOptim to compress images.
Just by implementing these simple optimizations you will achieve a noticeable improvement in terms of weight and page load time.
Be careful with images
The most common offender for poor responsive performance is downloading unnecessarily large images, or worse yet, multiple sizes of the same image.
For background images, simply being careful with where and how you include the image can ensure you don’t get caught in the trap of multiple background images being downloaded without being used. Don’t count on display:none to help. While it may hide elements from displaying on screen, those images will still be requested and downloaded.
Content images can be a little trickier. Whatever you do, don’t serve a large image that works on a large screen display to small screens. It’s wasteful, not only in terms of adding weight to the page, but also in wasting precious memory. Instead, use a tool like Adaptive Images or src.sencha.io to make sure only appropriately sized images are being downloaded.
The new <picture> element that has been so often discussed is another excellent solution if you’re feeling particularly future-oriented. A picture polyfill exists so that you can start using the element now without any worries about support.
Conditional loading
Don’t load any more than you absolutely need to. If a script isn’t needed at certain sizes, use the matchMedia polyfill to ensure it only loads when needed. Use eCSSential to do the same for unnecessary CSS files.
Last year on 24 ways, Jeremy Keith wrote an article about conditional loading of content in a responsive design based on the screen width. The technique was later refined by the Filament Group into what they dubbed the Ajax-Include Pattern. It’s a powerful and simple way to lighten the load on small screens as well as reduce clutter.
Go vanilla?
If you take a look at the HTTP Archive you’ll see that other than image size, JavaScript is the heaviest asset on a page weighing in at 215kb on average. It also boasts the fifth highest correlation to load time as well as the second highest correlation to render time.
Much of the weight can be attributed to our industry’s increasing reliance on frameworks. This is especially a concern on mobile devices. PPK recently exclaimed that current JavaScript libraries are just “too heavy for mobile”. “Research from Stoyan Stefanov on parse times supports this. On some Android and iOS devices, it can take as long as 200-300ms just to parse jQuery.
There’s nothing wrong about using a framework, but the problem is that they’ve become the default. Before dropping another framework or plugin into a page, we should stop to consider the value it adds and whether we could accomplish what we need to do using a combination of vanilla JavaScript and CSS instead. (This is a great example of a scenario where a performance budget could help.)
Start thinking beyond visual aesthetics
We love to tout the web’s universality when discussing the need for responsive design. But that universality is not limited simply to screen size. Networks and hardware capabilities must factor in as well.
The web is an incredibly dynamic and interactive medium, and designing for it demands that we consider more than just visual aesthetics. Let’s not forget to give those other qualities the attention they deserve. |

Starting Your Project on the Right Foot (and Keeping It There) |
I’m not sure if anything is as terrifying as beginning a new design project. I often spend hours trying to find the best initial footing in a design, so I’ve been working hard to improve my process, particularly for the earliest stages of a project. I want to smooth out the bumps that disrupt my creative momentum and focus on the emotional highs and lows I experience, and then try to minimize the lows and ride the highs as long as possible.
Design is often a struggle broken up by blissful moments of creative clarity that provide valuable force to move your work forward. Momentum is a powerful tool in creative work, and it’s something we don’t always maximize when we’re working because of the hectic nature of our field. Obviously, every designer is going to have a different process, but I thought I’d share some of the methods I’ve begun to adopt. I hope this will spark a conversation among designers who are interested in looking at process in a new way.
Jump-starting a project
I cannot overstate the importance of immersing yourself in design and collecting ample amounts of inspiration when beginning a project. I make it a daily practice to visit a handful of sites (Dribbble, Graphic Exchange, Web Creme, siteInspire, Designspiration, and others) and save any examples of design that I like. I then sort them into general categories (publication design, illustration, typography, web design, and so on). Enjoying a bit of fresh design every day helps me absorb it and analyze why it’s effective instead of just imitating it.
Many designers are afraid to look at too much design for fear that they’ll be tempted to copy it, but I feel a steady influx of design inspiration reduces that possibility. You’re much more likely to take the easy way out and rip off a design if you’re scrambling for inspiration after getting stuck. If you are immersed in design from a variety of mediums, you’ll engage your creative brain on multiple levels and have an easier time creating something unique for your project. Looking at good design will not make you a good designer but it will make you a better designer.
Design is design
Try not to limit your visual research to the medium you’re working in. Websites, books, posters and packaging all have their own unique limitations and challenges, and any one of those characteristics could be useful to you. Posters need to grab the viewer and pass on a small tidbit of information; packaging needs to encourage physical interaction; and websites need to encourage exploration. If you know the challenges you’ll be facing, you will know where to look for design that tackles those same problems.
I find it refreshing to look at design from the turn of the nineteenth century, when type was laid out on objects without thought to aesthetics. Many vintage packages break all sorts of modern design rules, and looking at that kind of work is a great way to spark your creativity. Pulling yourself out of the box and away from the rules of what you’re working on can reveal solutions that are innovative and unique. After a little finessing, the warning label text from a 1940s hazardous chemical box from could have the exact type and icon arrangement you need for your project. There’s a massive pool of design to pull from that doesn’t have the limitations the web has, and exploring those design worlds will help you grow your own repertoire.
If all else fails, start with the footer
The very beginning of a project is the most frustrating point in a project for me. I’m trying to figure out typeface combinations, colors and the overall voice of the design, and until I find the right solutions, I’m a wreck. I’ve found often that my frustration stems from trying to solve too many problems at once. The beginning of a project has a lot of moving targets, nearly endless possible solutions, and constantly changing variables. You’ll knock out one problem only to discover your solution doesn’t jive with something you worked out earlier — you end up designing in circles.
If you find yourself getting stuck at the beginning of a website design, try working out one specific element of the site and see what emerges. I’m going to recommend the footer. Why? Footers can easily be ignored in a design or become a dumping ground for items that couldn’t be worked into the main layout. But, at the start of most projects, the minimum content requirements for the footer are usually established. There needs to be a certain number of links, social media buttons, copyright details, a search bar, and so on. It’s a self-contained item within the design that has a specific purpose, and that’s a great element to focus on when you’re stuck in a design. Colors, typefaces, link styles, input fields and buttons can all be sketched out from just the footer. It’s a very flexible element that can be as prominent or subtle as you want, and it’s a solid starting point for setting the tone and style of a site.
Save the details
Designers love details. I love details. But don’t let nitpicking early on in your process kill your creative momentum. Design is an emotional process, and being frustrated or defeated by a tricky problem or a graphical detail you just can’t nail down can deflate your creative energies. If you hit a roadblock, set it aside and tackle another piece of the project. As you spend time engaged in a design, the style you develop will evolve according to the needs of the content, and you might arrive naturally at a solution that will work perfectly for the problem that had you stuck before.
If I find myself working on one particular element for more than a half an hour without any clear movement, I shelve it. Designers often wear their obsessive detail-oriented tendencies as a badge of honor, but there’s a difference between making the design better and wasting time. If you’ve spent hours nudging elements around pixel by pixel and can’t settle on something, it probably means what you’re doing isn’t making a huge improvement on the design. Don’t be afraid to let it lie and come at it again with fresh eyes. You will be better equipped to tackle the finer points of a project once you’ve got the broad strokes defined.
Have a plan when you start and stop designing
We all know that creativity isn’t something you can turn on effortlessly, and it’s easy to forget the emotional process that goes along with design. If you leave a project in a place of frustration, it’s going to stay with you in your free time and affect you negatively, like a dark cloud of impending disaster. Try to end each design session with a victory, a small bit of definable progress that you can take with you in your downtime. Even something as small as finding the right opacity for the interior shadow on the search bar in the header of the site is a win. Likewise, when you return to a project after a break, it can be difficult to get the ball rolling on the design again if you set it down without a clear path for the next steps. I find that I work on details best when I’m returning from downtime, when I’m fresh and re-energized and ready to dig in again. Try to pick out at least one element you’d like to fine-tune when you are winding down in a design session and use it to kick-start your next session.
Content is king
I would argue there is nothing more crucial to the success of a design than having the content defined from the outset. Designing without content is similar to designing without an audience, and designing with vague ideas of content types and character limits is going to result in a muted design that doesn’t reach its full potential. Images and language go hand in hand with design, and can take a design from functional to outstanding if you have them available from the outset. We don’t always have the luxury of having content to build a design around, but fight for it whenever you can. For example, if the site you are designing is full of technical jargon, your paragraphs might need a longer line length to accommodate the longer words being used.
Often, working with content will lead to design solutions you wouldn’t have come to otherwise. Design speaks to content, and content speaks to design. Lorem ipsum doesn’t speak to anyone (unless you know Latin, in which case, congratulations!).
Every project has its own set of needs, and every designer has his or her own method of working. There’s obviously no perfect process to design, and being dogmatic about process can be just as harmful as not having one. Exposing yourself to new design and new ways of designing is an easy way to test your skills and grow. When things are hard and you can’t get any momentum going on a design, this is when your skill set is truly challenged. We all hope to get wonderful projects with great assets and ample creative possibilities, but you won’t always be so blessed, and this is when the quality of your process is really going to shine. |

Flashless Animation |
Animation in a Flashless world
When I splashed down in web design four years ago, the first thing I wanted to do was animate a cartoon in the browser. I’d been drawing comics for years, and I’ve wanted to see them come to life for nearly as long. Flash animation was still riding high, but I didn’t want to learn Flash. I wanted to learn JavaScript!
Sadly, animating with JavaScript was limiting and resource-intensive. My initial foray into an infinitely looping background did more to burn a hole in my CPU than amaze my friends (although it still looks pretty cool). And there was still no simple way to incorporate audio. The browser technology just wasn’t there.
Things are different now. CSS3 transitions and animations can do most of the heavy lifting and HTML5 audio can serve up the music and audio clips. You can do a lot without leaning on JavaScript at all, and when you lean on JavaScript, you can do so much more!
In this project, I’m going to show you how to animate a simple walk cycle with looping audio. I hope this will inspire you to do something really cool and impress your friends. I’d love to see what you come up with, so please send your creations my way at rachelnabors.com!
Note: Because every browser wants to use its own prefixes with CSS3 animations, and I have neither the time nor the space to write all of them out, I will use the W3C standard syntaxes; that is, going prefix-less. You can implement them out of the box with something like Prefixfree, or you can add prefixes on your own. If you take the latter route, I recommend using Sass and Compass so you can focus on your animations, not copying and pasting.
The walk cycle
Walk cycles are the “Hello world” of animation. One of the first projects of animation students is to spend hours drawing dozens of frames to complete a simple loopable animation of a character walking.
Most animators don’t have to draw every frame themselves, though. They draw a few key frames and send those on to production animators to work on the between frames (or tween frames). This is meticulous, grueling work requiring an eye for detail and natural movement. This is also why so much production animation gets shipped overseas where labor is cheaper.
Luckily, we don’t have to worry about our frame count because we can set our own frames-per-second rate on the fly in CSS3. Since we’re trying to impress friends, not animation directors, the inconsistency shouldn’t be a problem. (Unless your friend is an animation director.)
This is a simple walk cycle I made of my comic character Tuna for my CSS animation talk at CSS Dev Conference this year:
The magic lies here:
animation: walk-cycle 1s steps(12) infinite;
Breaking those properties down:
animation: <name> <duration> <timing-function> <iteration-count>;
walk-cycle is a simple @keyframes block that moves the background sprite on .tuna around:
@keyframes walk-cycle {
0% {background-position: 0 0; }
100% {background-position: 0 -2391px;}
}
The background sprite has exactly twelve images of Tuna that complete a full walk cycle. We’re setting it to cycle through the entire sprite every second, infinitely. So why isn’t the background image scrolling down the .tuna container? It’s all down to the timing function steps(). Using steps() let us tell the CSS to make jumps instead of the smooth transitions you’d get from something like linear. Chris Mills at dev.opera wrote in his excellent intro to CSS3 animation :
Instead of giving a smooth animation throughout, [steps()] causes the animation to jump between a set number of steps placed equally along the duration. For example, steps(10) would make the animation jump along in ten equal steps. There’s also an optional second parameter that takes a value of start or end. steps(10, start) would specify that the change in property value should happen at the start of each step, while steps(10, end) means the change would come at the end.
(Seriously, go read his full article. I’m not going to touch on half the stuff he does because I cannot improve on the basics any more than he already has.)
The background
A cat walking in a void is hardly an impressive animation and certainly your buddy one cube over could do it if he chopped up some of those cat GIFs he keeps using in group chat. So let’s add a parallax background! Yes, yes, all web designers signed a peace treaty to not abuse parallax anymore, but this is its true calling—treaty be damned.
And to think we used to need JavaScript to do this! It’s still pretty CPU intensive but much less complicated. We start by splitting up the page into different layers, .foreground, .midground, and .background. We put .tuna in the .midground.
.background has multiple background images, all set to repeat horizontally:
background-image:
url(background_mountain5.png),
url(background_mountain4.png),
url(background_mountain3.png),
url(background_mountain2.png),
url(background_mountain1.png);
background-repeat: repeat-x;
With parallax, things in the foreground move faster than those in the background. Next time you’re driving, notice how the things closer to you move out of your field of vision faster than something in the distance, like a mountain or a large building. We can imitate that here by making the background images on top (in the foreground, closer to us) wider than those on the bottom of the stack (in the distance).
The different lengths let us use one animation to move all the background images at different rates in the same interval of time:
animation: parallax_bg linear 40s infinite;
The shorter images have less distance to cover in the same amount of time as the longer images, so they move slower.
Let’s have a look at the background’s animation:
@keyframes parallax_bg {
0% {
background-position: -2400px 100%, -2000px 100%, -1800px 100%, -1600px 100%, -1200px 100%;
}
100% {
background-position: 0 100%, 0 100%, 0 100%, 0 100%, 0 100%;
}
}
At 0%, all the background images are positioned at the negative value of their own widths. Then they start moving toward background-position: 0 100%. If we wanted to move them in the reverse direction, we’d remove the negative values at 0% (so they would start at 2400px 100%, 2000px 100%, etc.). Try changing the values in the codepen above or changing background-repeat to none to see how the images play together.
.foreground and .midground operate on the same principles, only they use single background images.
The music
After finishing the first draft of my original walk cycle, I made a GIF with it and posted it on YTMND with some music from the movie Paprika, specifically the track “The Girl in Byakkoya.” After showing it to some colleagues in my community, it became clear that this was a winning combination sure to drive away dresscode blues. So let’s use HTML5 to get a clip of that music looping in there!
Warning, there is sound. Please adjust your volume or apply headphones as needed.
We’re using HTML5 audio’s loop and autoplay abilities to automatically play and loop a sound file on page load:
<audio loop autoplay>
<source src="http://music.com/clip.mp3" />
</audio>
Unfortunately, you may notice there is a small pause between loops. HTML5 audio, thou art half-baked still. Let’s hope one day the Web Audio API will be able to help us out, but until things improve, we’ll have to hack our way around these shortcomings.
Turns out there’s a handy little script called seamlessLoop.js which we can use to patch this. Mind you, if we were really getting crazy with the Cheese Whiz, we’d want to get out big guns like sound.js. But that’d be overkill for a mere loop (and explaining the Web Audio API might bore, rather than impress your friends)!
Installing seamlessLoop.js will get rid of the pause, and now our walk cycle is complete.
(I’ve done some very rough sniffing to see if the browser can play MP3 files. If not, we fall back to using .ogg formatted clips (Opera and Firefox users, you’re welcome).)
Really impress your friends by adding a run cycle
So we have music, we have a walk cycle, we have parallax. It will be a snap to bring them all together and have a simple, endless animation. But let’s go one step further and knock the socks off our viewers by adding a run cycle.
The run cycle
Tacking a run cycle on to our walk cycle will require a third animation sequence: a transitional animation of Tuna switching from walking to running. I have added all these to the sprite:
Let’s work on getting that transition down. We’re going to use multiple animations on the same .tuna div, but we’re going to kick them off at different intervals using animation-delay—no JavaScript required! Isn’t that magical?
It requires a wee bit of math (not much, it doesn’t hurt) to line them up. We want to:
Loop the walk animation twice
Play the transitional cycle once (it has a finite beginning and end perfectly drawn to pick up between the last frame of the walk cycle and the first frame of the run cycle—no looping this baby)
RUN FOREVER.
Using the pattern animation: <name> <duration> <timing-function> <delay> <iteration-count>, here’s what that looks like:
animation:
walk-cycle 1s steps(12) 2,
walk-to-run .75s steps(12) 2s 1,
run-cycle .75s steps(13) 2.75s infinite;
I played with the times to get make the movement more realistic. You may notice that the running animation looks smoother than the walking animation. That’s because it has 13 keyframes running over .75 second instead of 12 running in one second. Remember, professional animation studios use super-high frame counts. This little animation isn’t even up to PBS’s standards!
The music: extended play with HTML5 audio sprites
My favorite part in the The Girl in Byakkoya is when the calm opening builds and transitions into a bouncy motif. I want to start with Tuna walking during the opening, and then loop the running and bounciness together for infinity.
The intro lasts for 24 seconds, so we set our 1 second walk cycle to run for 24 repetitions:
walk-cycle 1s steps(12) 24
We delay walk-to-run by 24 seconds so it runs for .75 seconds before…
We play run-cycle at 24.75 seconds and loop it infinitely
For the music, we need to think of it as two parts: the intro and the bouncy loop. We can do this quite nicely with audio sprites: using one HTML5 audio element and using JavaScript to change the play head location, like skipping tracks with a CD player. Although this technique will result in a small gap in music shifts, I think it’s worth using here to give you some ideas.
// Get the audio element
var byakkoya = document.querySelector('audio');
// create function to play and loop audio
function song(a){
//start playing at 0
a.currentTime = 0;
a.play();
//when we hit 64 seconds...
setTimeout(function(){
// skip back to 24.5 seconds and keep playing...
a.currentTime = 24.55;
// then loop back when we hit 64 again, or every 59.5 seconds.
setInterval(function(){
a.currentTime = 24.55;
},39450);
},64000);
}
The load screen
I’ve put it off as long as I can, but now that the music and the CSS are both running on their own separate clocks, it’s imperative that both images and music be fully downloaded and ready to run when we kick this thing off. So we need a load screen (also, it’s nice to give people a heads-up that you’re about to blast them with music, no matter how wonderful that music may be).
Since the two timers are so closely linked, we’d best not run the animations until we run the music:
* { animation-play-state: paused; }
animation-play-state can be set to paused or running, and it’s the most useful thing you will learn today.
First we use an event listener to see when the browser thinks we can play through from the beginning to end of the music without pause for buffering:
byakkoya.addEventListener("canplaythrough", function () { });
(More on HTML5 audio’s media events at HTML5doctor.com)
Inside our event listener, I use a bit of jQuery to add class of .playable to the body when we’re ready to enable the play button:
$("body").addClass("playable");
$("#play-me").html("Play me.").click(function(){
song(byakkoya);
$("body").addClass("playing");
});
That .playing class is special because it turns on the animations at the same time we start playing the song:
.playing * { animation-play-state: running; }
The background
We’re almost done here! When we add the background, it needs to speed up at the same time that Tuna starts running. The music picks up speed around 24.75 seconds in, and so we’re going to use animation-delay on those backgrounds, too.
This will require some math. If you try to simply shorten the animation’s duration at the 24.75s mark, the backgrounds will, mid-scroll, jump back to their initial background positions to start the new animation! Argh! So let’s make a new @keyframe and calculate where the background position would be just before we speed up the animation.
Here’s the formula:
new 0% value = delay ÷ old duration × length of image
new 100% value = new 0% value + length of image
Here’s the formula put to work on a smaller scale:
Voilà! The finished animation!
I’ve always wanted to bring my illustrations to life. Then I woke up one morning and realized that I had all the tools to do so in my browser and in my head. Now I have fallen in love with Flashless animation.
I’m sure there will be detractors who say HTML wasn’t meant for this and it’s a gross abuse of the DOM! But I say that these explorations help us expand what we expect from devices and software and challenge us in good ways as artists and programmers. The browser might not be the most appropriate place for animation, but is certainly a fun place to start.
There is so much you can do with the spec implemented today, and so much of the territory is still unexplored. I have not yet begun to show you everything. In eight months I expect this demo will represent the norm, not the bleeding edge. I look forward to seeing the wonderful things you create.
(Also, someone, please, do something about that gappy HTML5 audio looping. It’s a crying shame!) |

Content Planning Demystified |
The first thing you learn as a junior editor is that you can’t do everything yourself. You must rely on someone else to do at least part of what must be done: the long-range planning, the initial drafting or shooting or recording, the editing, the production, the final polish. All of those pieces of work that belong to someone else take quite a lot of time — days, weeks, sometimes months. If you’re the sort of person who wrote college term papers the night before they were due, this can come as a bit of a shock. To my twenty-two-year-old self, it certainly did.
It turns out that the only real way to avoid a trainwreck with editorial work is to get ahead of the trouble, line everything up carefully, and leave oodles of room for all the pieces to connect on time. The same is true of content strategy, content planning, and just about everything to do with content on the web, except for the writing itself — and that, too, usually takes far longer than anyone expects. If you’re not a professional editor and you suddenly find yourself dealing with content creation, you’re almost certainly going to underestimate the time and effort involved, or to skip something important in the planning process that pops up to bite you later.
Without good content, it doesn’t matter how well designed or coded your web project is, because it won’t be doing the thing it’s meant to do. And even if content is far from your specialty, you may well end up being the only one willing to coordinate it far enough in advance to avoid a chaotic ending. Whether you’re hiring writers and editors for a big project, working with a small client, or coaxing some editorial help out of a co-worker, getting the planning work done correctly — and ahead of time — will allow you to orchestrate a glorious ballet of togetherness, instead of feverishly scraping together something to put on your site when the deadline looms. So get out the graph paper and the pocket protector, because we’re going to go Full Nerd on this problem.
Know your poison
Anyone who’s seen a project delayed for six months by content trouble, or derailed by content that’s bland and unhelpful, knows this stuff can make you feel like a dead sock. To get ahead of the problem, you’re going to have to learn to spot common problems and plan your way around them. On web projects without a dedicated editorial lead, you’re likely to encounter content that is:
Useless – Content that doesn’t serve your readers’ needs in some way is pointless. And because it takes up your time and crowds out genuinely helpful things, it’s actually damaging. The logic is simple: you can make content that’s all about you, and that serves your stated messaging goals, but if no one is motivated to read it, it’s a waste of everyone’s time.
Badly written – When you publish articles or instructions or other content that is too stiffly formal, overly wordy, hard to understand, offensive, unintentionally cheesy, or otherwise off in tone or style, you’re doing two things. First, you’re weakening the information you’re trying to convey by making it obscure or annoying. Second — and this one is even more damaging — you’re demonstrating bad taste. When you get the cultural elements of publishing wrong, you encourage your readers to believe that you either don’t understand them or don’t care about getting it wrong.
Gooey – Content strategists have been talking about structured content (that’s chunks versus blobs) for years. If you’re publishing more than a few dozen pages without thinking through the structure of your content, you’re probably missing a chance to improve your long-term efficiency. If you’re publishing more than a couple of thousand pages without taking care of your content structure, you’re probably doing a lot more manual wrangling (or cumbersome CMS work) than you need to be, especially when it comes to cross-platform publishing.
Unregulated – If you’re not tracking what works and what doesn’t — and especially if you don’t know what “works” means for your project or organization — you’re almost certainly getting worse results than you should be, for more work.
Overabundant – As demonstrated by the cinnamon challenge, too much of a delicious thing can be a giant and publicly embarrassing disaster. For most projects and organizations, if you’re making more stuff than your readers can handle, or if you’re spreading your creative and editorial resources too thinly, that’s bad. Spammers, content farms, and barrel-bottom tabloids have their own special math, the side effects of which include insomnia, irritability, and crying in traffic while silently mouthing Wilson Phillips lyrics.
Prevent all preventable damage
Once you know what kind of trouble to look for, you can prevent a lot of it by doing some smart planning well before someone starts writing (or recording or shooting video).
To prevent uselessness: Know your readers and decide what you’re trying to accomplish — with your website as a whole, and with each piece of content, always. Once you know what you’re trying to achieve, you can evaluate your work as you go to make sure that it’s actually doing the right thing. (I’ve written a lot more about this for A List Apart and in The Elements of Content Strategy.)
To prevent bad writing: Establish a consistent and appropriate style using examples (and a style guide if you need one), designate an editor, hire good writers, and make time for quality control. Kate Kiefer’s style guide for MailChimp is a superb example of style-wrangling that everyone can use.
To prevent repulsive goo: Give your content as much structure as possible, and know how structure relates to your entire publishing ecosystem, including all those mobile devices. Sara Wachter-Boettcher’s Content Everywhere and Karen McGrane’s Content Strategy for Mobile offer brilliant yet friendly introductions to the wide world of structured content.
To prevent unregulated chaos: Measure everything that matters to your project, your client, your organization, and especially your readers — not generic measures of someone else’s success. Measure it all regularly. Be disciplined. Adjust at regular intervals. Rick Allen’s series on content strategy analytics is an excellent place to begin (part one; part two).
To prevent overabundance: Stop trying to do everything and focus on giving your readers just a few things they want and genuinely need. Don’t establish a schedule your writers might not be able to keep, and focus on differentiating yourself with quality, not quantity. (And while you’re at it, scratch the auto-posting to social networks and the cross-posting between them. It’s about as engaging as an automated phone system.)
At a slightly higher level, pick the right content person (or team) for the work. If you really only need a few pages of copy, find a smart writer who does good work for multi-platform readers. If you’re slinging tens of thousands of pages of content, get someone with field experience in high-level editorial planning and the ability to turn blobs into chunks and melted goo into Legos. If you’re starting a project that involves making a lot of content over time, bring in someone with journalism experience (or get your client to do so).
“But wait!” you may say. “I’m not hiring anyone. I have to do this all myself.” That’s not uncommon at all. The bad news is, you have to learn a bunch of stuff. The good news is, you get to learn a bunch of awesome stuff. Figure out what the project needs, just as though you were going to hire someone, and then give yourself time to get up to speed. If it’s a really complicated project, you’re probably going to have trouble unless you eventually get professional help. But if it’s small and you can do it in steps, you can certainly do much better by giving yourself a plan and working on the things that matter most.
Plan for the marathon, not the sprint
Launching with awesome content is a tiny fraction of a victory, which is why it’s so important that your content not be gooey or unregulated. It also means that if you don’t plan for a realistic publication schedule, you are going to slam into reality in a really unpleasant way not too long after you’ve begun. If you’re asking people to make words (or videos or whatever) for you, they’re going to have to do less of something else, so plan for that beforehand.
And while you’re at it, unless publishing is your core business, ditch the feed-the-beast plan that leads to fluffy blog posts and spiritless, unhelpful social media content. It’s antisocial for your reading community, offers short-term gains at best, and will burn you out or lower your standards until you don’t even know you’re doing lousy work. Good content is expensive, no matter how you do it, but spreading yourself too thin is a much worse investment than doing a smaller thing well and gradually building up a body of superb content that people want to share and keep and return to. |

Think First, Code Later |
This is a story that’s best told from the end, and it’s probably one you’re all familiar with.
You, or someone just like you, have been building a website, probably as part of a skilled and capable team. You’re a front-end developer, focusing on JavaScript – it’s either your sole responsibility or shared around. It’s quite a big job, been going on for months, and at last it feels like you’re reaching the end of it.
But, in a brief moment of downtime, you step back and take a look at the code as a whole. You notice that the folder called “jQuery plugins” suddenly looks rather full, and maybe there’s evidence of several methods of doing the same thing; there are loads of little niggly fixes in the bug tracker; and every place you use Ajax the structure of the data is slightly different. You sigh, and your shoulders droop slightly, and you think “Yeah, we’ll do that more cleanly next time.”
The thing is, you probably already know how to rewrite the start of this story to make the ending work better. This situation is not really anyone’s fault – it’s just an accumulation of all the things you decided along the way, all the things you agreed you’d fix later that have disappeared into the black hole of technical debt, and accomodating all the “can we just…?” requests from around the team and the client.
So, the solution to this is easy, right? More interminable planning meetings, more tightly controlled and documented specifications, less freedom to innovate, to try out new ideas and enjoy what you’re doing.
Wait, that sounds even less fun than the old way.
Minimum viable planning
Actually, planning and specifications are exactly what you need, but the way you go about them can make a real difference, both to the quality of your code, and the quality of your life as a developer. It can be as simple as being a little more thoughtful before starting on any new piece of functionality. Involve your whole team if possible, or at least those working on what you’re doing. Canvass opinions and work out what the solution to the problem might look like first, rather than coding speculatively to find out.
There are easy ways you can get into this habit of putting the thought and design up front, and it doesn’t have to mean spending more time on the project as a whole. It also doesn’t have to result in reams of functional specifications. Instead, let the code itself form the specification.
As JavaScript applications become more complex, unit testing is becoming ever more important. So embrace it, whether you prefer QUnit, or Mocha, or any of the other JavaScript testing frameworks out there. The TDD (or test-driven development) pattern is all about writing the tests first and then writing functional code to pass those tests; or, if you prefer, code that meets the specification given by the tests.
Sounds like a hassle at first, but once you get into the rhythm of it you should find that the time spent writing tests up front is no greater, and often significantly less, than the time you would have spent fixing bugs afterwards.
If what you’re working on requires an API between client and server (usually Ajax but this can apply to any method of sending or receiving data) then spend a bit of time with the back-end developer to design the data contracts, before either of you cut any code. Work out what the API endpoints are going to be, and what the data structure you’ll get back from a certain endpoint looks like. A mock JSON object documented on a wiki is enough and it can be atomic. Don’t worry about planning the entire project at once, just plan enough to get on with your current tasks.
Definition in this way doesn’t have to make your API immutable – change is still fine – but if you know roughly where you’re heading, then not only can your team’s efforts become more parallel, but you’re far more likely to have an easier time making it all work. And again, you have a specification – the shape of the data – to write your JavaScript against.
Putting everything together, you end up with a logical flow of development, from the specification agreed with the client (your backlog), to the specification agreed with your team (the API contract design), to the specification agreed with your code (your unit tests). Hopefully, there will be ample clues in all of this to inform your front-end library choices, because by then you should have a better picture of what you’re going to need.
What the framework?
As a JavaScript developer predominantly, these are the choices I’m particularly interested in – how and why you use JavaScript libraries and frameworks, both what you expect from them and what you actually get.
If we look back at how web development, and specifically JavaScript development has progressed – from the earliest days of using lines and lines of Dreamweaver code-barf to make an image rollover effect, to today’s large frameworks that handle working with the DOM, Ajax communication and visual effects all in one hit – the purpose of it is clear: to smooth over the inconsistent bumps between browsers and give a solid, reliable, predictable base on which to put our desired functionality.
Understanding what we expect the language as a specification to do, and matching that to what we observe browsers actually doing, and then smoothing out the differences, is a big job. Since the language and the implementations are also changing as we go along, it also feels like a never-ending job. So make full use of this valuable effort. Use jQuery or YUI or anything else you’re comfortable with, but it still pays to think early on about what you need your library to do and what the best choice is to meet that need.
I’ve come in to projects as a fixer and found, to take a recent example, that jQuery UI was being used just to provide a date picker and a modal effect. That’s a lot of code weight to provide two fairly simple pieces of functionality that could easily be covered by smaller plugins. Which isn’t to say that jQuery UI itself is a bad choice, but I could see that it had been included late on just to do those things, whereas a more considered approach would have been to put the library in early and use it more universally.
There are other choices, too. If you automatically throw in jQuery (or whatever your favourite main library is) to a small site with limited functionality, you might only touch a tiny fraction of its scope. In my own development I started looking at what I actually needed from a JavaScript library. For a simple project like What the Framework?, all jQuery needed to do was listen for .ready() and then perform some light DOM selection before handing over to a client-side MVC framework. So perhaps there was another way to go about this while still avoiding the cross-browser headaches.
Deleting jQuery
But the jQuery pattern is compelling and familiar. And once you’re comfortable with something, it’s a bit of an effort to force yourself out of that comfort zone and learn. But looking back at my whole career, I realised that I’ve relearned pretty much everything I do, probably several times, since I started out. So it’s worth keeping in mind that learning and trying new things is how development has advanced to where it is now, and how it will keep advancing in the future.
In the end this lead me to Ender, which is billed as an NPM-style package manager for the browser, letting you search for and manage small, loosely coupled modules and their dependencies, and compile them to one file with a common API.
For What the Framework I ended up with a set of DOM tools, Underscore and Knockout, all minified into 25kb of JavaScript. This compares really well with 32kb minified for jQuery on its own, and Ender’s use of the dollar variable and the jQuery-like syntax in many modules makes switching over a low-friction experience.
On more complex projects, where you’re really going to use all the features of something like jQuery, but want to minimise the loading of other dependencies when you don’t need them, I’ve recently started looking at Jam. This uses the RequireJS pattern to compile commonly used code into a library file and then manage dependencies and bring in others on a per-page basis depending on how you need it. Again, it all comes down to thinking about what you need and using it only when you need it. And the configurability of tools like Ender or Jam allow you to be responsive to changing requirements as your project grows.
There is no right answer
That’s not to say this way of working automatically makes things easier. It doesn’t. On a large, long-running project or one where future functionality is unknown, it’s still hard to predict and plan for everything – at least until crystal balls as a service come about. But by including strong engineering practices in your front-end, and trying to minimise technical debt, you’re at least giving yourself a decent safety net to guard against the “can we just…?” tendencies that are a fact of life.
So, really, this is not an advocation of using a particular technology or framework, because I can’t tell you what works for you or your team. But what I can tell you is that working this way round has done wonders for my productivity and enthusiasm, both for code quality and for trying out new libraries. Give it a go, you might like it! |

Direction, Distance and Destinations |
With all these new smartphones in the hands of lost and confused owners, we need a better way to represent distances and directions to destinations. The immediate examples that jump to mind are augmented reality apps which let you see another world through your phone’s camera. While this is interesting, there is a simpler way: letting people know how far away they are and if they are getting warmer or colder.
In the app world, you can easily tap into the phone’s array of sensors such as the GPS and compass, but what people rarely know is that you can do the same with HTML. The native versus web app debate will never subside, but at least we can show you how to replicate some of the functionality progressively in HTML and JavaScript.
In this tutorial, we’ll walk through how to create a simple webpage listing distances and directions of a few popular locations around the world. We’ll use JavaScript to access the device’s geolocation API and also attempt to access the compass to get a heading. Both of these APIs are documented, to be included in the W3C geolocation API specification, and can be used on both desktop and mobile devices today.
To get started, we need a list of a few locations around the world. I have chosen the highest mountain peak on each continent so you can see a diverse set of distances and directions.

Source: Wikipedia
We can put those into an HTML list to be styled and accessed by JavaScript to create some distance and directions calculations.
The next thing we need to do is check to see if the browser and operating system have geolocation support. To do this we test to see if the function is available or not using a single JavaScript if statement.
<script>
// If this is true, then the method is supported and we can try to access the location
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(geo_success, geo_error);
}
</script>
The if statement will be false if geolocation support is not present, and then it is up to you to do something else instead as a fallback. For this example, we’ll do nothing since our page should work as is and only get progressively better if more functionality is available.
The if statement will be true if there is support and therefore will continue inside the curly brackets to try to get the location. This should prompt the reader to accept or deny the request to get their location. If they say no, the second function callback is processed, in this case a function called geo_error; whereas if the location is available, it fires the geo_success function callback.
The function geo_error(){ } isn’t that exciting. You can handle this in any way you see fit. The success function is more interesting. We get a position object passed into the function which contains a series of exciting attributes, namely the latitude and longitude of the device’s current location.
function geo_success(position){
gLat = position.coords.latitude;
gLon = position.coords.longitude;
}
Now, in the variables gLat and gLon we have the user’s approximate geographical position. We can use this information to start to calculate some distances between where they are and all the destinations.
At the time of writing, you can also get position.coords.heading, but on Windows and iOS devices this returned NULL. In the future, if and when this is supported, this is also where you can easily grab the compass information.
Inside the geo_success function, we want to loop through the HTML to get all of the mountain peaks’ latitudes and longitudes and compute the distance.
...
$('.geo').each(function(){
// Get the lat/lon from the HTML
tLat = $(this).find('.lat').html()
tLon = $(this).find('.lon').html()
// compute the distances between the current location and this points location
dist = distance(tLat,tLon,gLat,gLon);
// set the return values into something useful
d = parseInt(dist[0]*10)/10;
a = parseFloat(dist[1]);
// display the value in the HTML and style the arrow
$(this).find('.distance').html(d+' km away');
$(this).find('.direction').css('-webkit-transform','rotate(-' + a + 'deg)');
// store the arc for later use if compass is available
$(this).attr('data-arc',a);
}
In the variable d we have the distance between the current location and the location of the mountain peak based on the Haversine Formula. The variable a is the arc, which has a value from 0 to 359.99. This will be useful later if we have compass support. Given these two values we have a distance and a heading to style the HTML.
The next thing we want to do is check to see if the device has a compass and then get access to the the current heading. As we’ll see, there are several ways to do this, some of which work on certain devices but not others. The W3C geolocation spec says that, along with the coordinates, there are several other attributes: accuracy; altitude; and heading. Heading is the direction to true north, which is different than magnetic north! WebKit and Windows return NULL for the heading value, but WebKit has an experimental method to fetch the heading. If you get into accessing these sensors, you’ll have to try to catch a few of these methods to finally get a value. Assuming you do, we can move on to the more interesting display opportunities.
In an ideal world, this would succeed and set a variable we’ll call compassHeading to get a value between 0 and 359.99 degrees. Now we know which direction north is, we also know the direction relative to north of the path to our destination, so we can can subtract the two values to get an arrow to display on the screen. But we’re not finished yet: we also need to get the device’s orientation (landscape or portrait) and subtract the correct amount from the angle for the arrow. Once we have a value, we can use CSS to rotate the arrow the correct number of degrees.
-webkit-transform: rotate(-180deg)
Not all devices support a standard way to access compass information, so in the meantime we need to use a work around. On iOS, you can use the experimental event method e.webkitCompassHeading. We want the compass to update in real time as the device is moved around, so we’ll put this inside an event listener.
window.addEventListener('deviceorientation', function(e) {
// Loop through all the locations on the page
$('.geo').each(function(){
// get the arc value from north we computed and stored earlier
destination_arc = parseInt($(this).attr('data-arc'))
compassHeading = e.webkitCompassHeading + window.orientation + destination_arc;
// find the arrow element and rotate it accordingly
$(this).find('.direction').css('-webkit-transform','rotate(-' + compassHeading + 'deg)');
}
}
As the device is rotated, the compass arrow will constantly be updated. If you want to see an example, you can have a look at this page which shows the distances to all the peaks on each continent.
With progressive enhancement, we slowly layer on additional functionality as we go. The reader will first see the list of locations with a latitude and longitude. If the device is capable and permissions allow, it will then compute the distance. If a compass is available, with the correct permissions it will then add the final layer which is direction.
You should consider this code a stub for your projects. If you are making a hyperlocal webpage with restaurant locations, for example, then consider adding these features. Knowing not only how far away a place is, but also the direction can be hugely important, and since the compass is always active, it acts as a guide to the location.
Future developments
Improvements to this could include setting a timer and recalling the navigator.geolocation.getCurrentPosition() function and updating the distances. I chose very distant mountains so kilometres made sense, but you can divide again by 1,000 to convert to metres if you are dealing with much nearer places. Walking or driving would change the distances so the ability to refresh would be important.
It is outside the scope of this article, but if you manage to get this HTML to work offline, then you can make a nice web app which sits on your devices’ homescreens and works even without an internet connection. This could be ideal for travellers in an unknown city looking for your destination. Just with offline storage, base64 encoding and data URIs, it is possible to embed plenty of design and functionality into a small offline webpage.
Now you know how to use JavaScript to look up a destination’s location and figure out the distance and direction – never get lost again. |

Monkey Business |
“Too expensive.” “Over-priced.” “A bit rich.”
They all mean the same thing.
When you say that something’s too expensive, you’re doing much more than commenting on a price. You’re questioning the explicit or implicit value of a product or a service. You’re asking, “Will I get out of it what you want me to pay for it?” You’re questioning the competency, judgement and possibly even integrity of the individual or company that gave you that price, even though you don’t realise it. You might not be saying it explicitly, but what you’re implying is, “Have you made a mistake?”, “Am I getting the best deal?”, “Are you being honest with me?”, “Could I get this cheaper?”
Finally, you’re being dishonest, because deep down you know all too well that there’s no such thing as too expensive.
Why?
It doesn’t matter what you’re questioning the price of. It could be a product, a service or the cost of an hour, day or week of someone’s time. Whatever you’re buying, too expensive is always an excuse. Saying it shifts acceptability of a price back to the person who gave it. What you should say, but are too afraid to admit, is:
“It’s more money than I wanted to pay.”
“It’s more than I estimated it would cost.”
“It’s more than I can afford.”
Everyone who’s given a price for a product or service will have been told at some point that it’s too expensive. It’s never comfortable to hear that. Thoughts come thick and fast: “What do I do?” “How do I react?” “Do I really want the business?” “Am I prepared to negotiate?” “How much am I willing to compromise?”
It’s easy to be defensive when someone questions a price, but before you react, stay calm and remember that if someone says what you’re offering is too expensive, they’re saying more about themselves and their situation than they are about your price. Learn to read that situation and how to follow up with the right questions.
Imagine you’ve quoted someone for a week of your time. “That’s too expensive,” they respond. How should you handle that? Think about what they might otherwise be saying.
“It’s more money than I want to pay” may mean that they don’t understand the value of your service. How could you respond?
Start by asking what similar projects they’ve worked on and the type of people they worked with. Find out what they paid and what they got for their money, because it’s possible what you offer is different from what they had before. Ask if they saw a return on that previous investment. Maybe their problem isn’t with your headline price, but the value they think they’ll receive. Put the emphasis on value and shift the conversation to what they’ll gain, rather than what they’ll spend.
It’s also possible they can’t distinguish your service from those of your competitors, so now would be a great time to explain the differences. Do you work faster? Explain how that could help them launch faster, get customers faster, make money faster. Do you include more? Emphasise that, and how unique the experience of working with you will be.
“It’s more than I estimated it would cost” could mean that your customer hasn’t done their research properly. You’d never suggest that to them, of course, but you should ask how they’ve arrived at their estimate. Did they base it on work they’ve purchased previously? How long ago was that? Does it come from comparable work or from a different sector?
Help your customer by explaining how you arrived at your estimate. Break down each element and while you’re doing that, emphasise the parts of your process that you know will appeal to them. If you know that they’ve had difficulty with something in the past, explain how your approach will benefit them. People almost always value a positive experience more than the money they’ll save.
“It’s more than I can afford” could mean they can’t afford what you offer at all, but it could also mean they can’t afford it right now or all at once. So ask if they could afford what you’re asking if they spread payment over a longer period? Ask, “Would that mean you’ll give me the business?”
It’s possible they’re asking for too much for what they can afford to pay. Will they compromise? Can you reach an agreement on something less? Ask, “If we can agree what’s in and what’s out, will you give me the business?”
What can they afford? When you know, you’re in a good position to decide if the deal makes good business sense, for both of you. Ask, “If I can match that price, will you give me the business?”
There’s no such thing as “a bit rich”, only ways for you to get to know your customer better. There’s no such thing as “over-priced”, only opportunities for you to explain yourself better. You should relish those opportunities. There’s really also no such thing as “too expensive”, just ways to set the tone for your relationship and help you develop that relationship to a point where money will be less of a deciding factor.

Infinite Canvas: Moving Beyond the Page |
Remember Web 2.0? I do. In fact, that phrase neatly bifurcates my life on the internet. Pre-2.0, I was occupied by chatting on AOL and eventually by learning HTML so I could build sites on Geocities. Around 2002, however, I saw a WYSIWYG demo in Dreamweaver. The instructor was dragging boxes and images around a canvas. With a few clicks he was able to build a dynamic, single-page interface. Coming from the world of tables and inline HTML styles, I was stunned.
As I entered college the next year, the web was blossoming: broadband, Wi-Fi, mobile (proud PDA owner, right here), CSS, Ajax, Bloglines, Gmail and, soon, Google Maps. I was a technology fanatic and a hobbyist web developer. For me, the web had long been informational. It was now rapidly becoming something else, something more: sophisticated, presentational, actionable.
In 2003 we watched as the internet changed. The predominant theme of those early Web 2.0 years was the withering of Internet Explorer 6 and the triumph of web standards. Upon cresting that mountain, we looked around and collectively breathed the rarefied air of pristine HMTL and CSS, uncontaminated by toxic hacks and forks – only to immediately begin hurtling down the other side at what is, frankly, terrifying speed.
Ten years later, we are still riding that rocket. Our days (and nights) are spent cramming for exams on CSS3 and RWD and Sass and RESS. We are the proud, frazzled owners of tiny pocket computers that annihilate the best laptops we could have imagined, and the architects of websites that are no longer restricted to big screens nor even segregated by device. We dragoon our sites into working any time, anywhere. At this point, we can hardly ask the spec developers to slow down to allow us to catch our breath, nor should we. It is, without a doubt, a most wonderful time to be a web developer.
But despite the newfound luxury of rounded corners, gradients, embeddable fonts, low-level graphics APIs, and, glory be, shadows, the canyon between HTML and native appears to be as wide as ever. The improvements in HTML and CSS have, for the most part, been conveniences rather than fundamental shifts. What I’d like to do now, if you’ll allow me, is outline just a few of the remaining gaps that continue to separate web sites and applications from their native companions.
What I’d like for Christmas
There is one irritant which is the grandfather of them all, the one from which all others flow and have their being, and it is, simply, the page refresh. That’s right, the foundational principle of the web is our single greatest foe. To paraphrase a patron saint of designers everywhere, if you see a page refresh, we blew it.
The page refresh brings with it, of course, many noble and lovely benefits: addressability, for one; and pagination, for another. (See also caching, resource loading, and probably half a dozen others.) Still, those concerns can be answered (and arguably answered more compellingly) by replacing the weary page with the young and hearty document. Flash may be dead, but it has many lessons yet to bequeath.
Preparing a single document when the site loads allows us to engage the visitor in a smooth and engrossing experience. We have long known this, of course. Twitter was not the first to attempt, via JavaScript, to envelop the user in a single-page application, nor the first to abandon it. Our shared task is to move those technologies down the stack, to make them more primitive, so that the next Twitter can be built with the most basic combination of HTML and CSS rather than relying on complicated, slow, and unreliable scripted solutions.
So, let’s take a look at what we can do, right now, that we might have a better idea of where our current tools fall short.
A print magazine in HTML clothing
Like many others, I suspect, one of my earliest experiences with publishing was laying out newsletters and newspapers on a computer for print. If you’ve ever used InDesign or Quark or even Microsoft Publisher, you’ll remember reflowing content from page to page. The advent of the internet signaled, in many ways, the abandonment of that model. Articles were no longer constrained by the physical limitations of paper. In shedding our chains, however, it is arguable that we’ve lost something useful. We had a self-contained and complete package, a closed loop. It was a thing that could be handled and finished, and doing so provided a sense of accomplishment that our modern, infinitely scrolling, ever-fractal web of content has stolen.
For our purposes today, we will treat 24 ways as the online equivalent of that newspaper or magazine. A single year’s worth of articles could easily be considered an issue. Right now, navigating between articles means clicking on the article you’d like to view and being taken to that specific address via a page reload. If Drew wanted to, it wouldn’t be difficult to update the page in place (via JavaScript) and change the address (again via JavaScript with the History API) to reflect the new content found at the new location. But what if Drew wanted to do that without JavaScript? And what if he wanted the site to not merely load the content but actually whisk you along the page in a compelling and delightful way, à la the Mag+ demo we all saw a few years ago when the iPad was first introduced? Uh, no.
We’re all familiar with websites that have attempted to go beyond the page by weaving many chunks of content together into a large document and for good reason. There is tremendous appeal in opening and exploring the canvas beyond the edges of our screens.
In one rather straightforward example from last year, Mozilla contacted Full Stop to build a website promoting Aza Raskin’s proposal for a set of Creative Commons-style privacy icons. Like a lot of the sites we build (including our own), the amount of information we were presenting was minimal. In these instances, we encourage our clients to consider including everything on a single page. The result was a horizontally driven site that was, if not whimsical, at least clever and attractive to the intended audience. An experience that is taken for granted when using device-native technology is utterly, maddeningly impossible to replicate on the web without jumping through JavaScript hoops.
In another, more complex example, we again had the pleasure of working with Aza earlier this year, this time on a redesign of the Massive Health website. Our assignment was to design and build a site that communicated Massive’s commitment to modern personal health. The site had to be visually and interactively stunning while maintaining a usable and clear interface for the casual visitor. Our solution was to extend the infinite company logo into a ribbon that carried the visitor through the site narrative. It also meant we’d be asking the browser to accommodate something it was never designed to handle: a non-linear design. (Be sure to play around. There’s a lot going on under the hood. We were also this close to a ZUI, if WebKit didn’t freak out when pages were scaled beyond 10×.) Despite the apparent and deliberate design simplicity, the techniques necessary to implement it are anything but. From updating the URL to moving the visitor from section to section, we’re firmly in JavaScript territory. And that’s a shame.
What can we do?
We might not be able to specify these layouts in HTML and CSS just yet, but that doesn’t mean we can’t learn a few new tricks while we wait. Let’s see how close we can come to recreating the privacy icons design, the Massive design, or the Mag+ design without resorting to JavaScript.
A horizontally paginated site
The first thing we’re going to need is the concept of a page within our HTML document. Using plain old HTML and CSS, we can stack a series of <div>s sideways (with a little assist from our new friend, the viewport-width unit, not that he was strictly necessary). All we need to know is how many pages we have. (And, boy, wouldn’t it be nice to be able to know that without having to predetermine it or use JavaScript?)
.window {
overflow: hidden;
width: 100%;
}
.pages {
width: 200vw;
}
.page {
float: left;
overflow: hidden;
width: 100vw;
}
If you look carefully, you’ll see that the conceit we’ll use in the rest of the demos is in place. Despite the document containing multiple pages, only one is visible at any given time. This allows us to keep the user focused on the task (or content) at hand.
By the way, you’ll need to use a modern, WebKit-based browser for these demos. I recommend downloading the WebKit nightly builds, Chrome Canary, or being comfortable with setting flags in Chrome.
A horizontally paginated site, with transitions
Ah, here’s the rub. We have functional navigation, but precious few cues for the user. It’s not much good shoving the visitor around various parts of the document if they don’t get the pleasant whooshing experience of the journey. You might be thinking, what about that new CSS selector, target-something…? Well, my friend, you’re on the right track. Let’s test it. We’re going to need to use a bit of sleight of hand. While we’d like to simply offset the containing element by the number of pages we’re moving (like we did on Massive), CSS alone can’t give us that information, and that means we’re going to need to fake it by expanding and collapsing pages as you navigate. Here are the bits we’re going to need:
.page {
-webkit-transition: width 1s; // Naturally you're going to want to include all the relevant prefixes here
float: left;
left: 0;
overflow: hidden;
position: relative;
width: 100vw;
}
.page:not(:target) {
width: 0;
}
Ah, but we’re not fooling anyone with that trick. As soon as you move beyond a single page, the visitor’s disbelief comes tumbling down when the linear page transitions are unaffected by the distance the pages are allegedly traveling. And you may have already noticed an even more fatal flaw: I secretly linked you to the first page rather than the unadorned URL. If you visit the same page with no URL fragment, you get a blank screen. Sure, we could force a redirect with some server-side trickery, but that feels like cheating. Perhaps if we had the CSS4 subject selector we could apply styles to the parent based on the child being targeted by the URL. We might also need a few more abilities, like determining the total number of pages and having relative sibling selectors (e.g. nth-sibling), but we’d sure be a lot closer.
A horizontally paginated site, with transitions – no cheating
Well, what other cards can we play? How about the checkbox hack? Sure, it’s a garish trick, but it might be the best we can do today. Check it out.
label {
cursor: pointer;
}
input {
display: none;
}
input:not(:checked) + .page {
max-height: 100vh;
width: 0;
}
Finally, we can see the first page thanks to the state we are able to set on the appropriate radio button. Of course, now we don’t have URLs, so maybe this isn’t a winning plan after all. While our HTML and CSS toolkit may feel primitive at the moment, we certainly don’t want to sacrifice the addressability of the web. If there’s one bedrock principle, that’s it.
A horizontally paginated site, with transitions – no cheating and a gorgeous homepage
Gorgeous may not be the right word, but our little magazine is finally shaping up. Thanks to the CSS regions spec, we’ve got an exciting new power, the ability to begin an article in one place and bend it to our will. (Remember, your everyday browser isn’t going to work for these demos. Try the WebKit nightly build to see what we’re talking about.) As with the rest of the examples, we’re clearly abusing these features. Off-canvas layouts (you can thank Luke Wroblewski for the name) are simply not considered to be normal patterns… yet.
Here’s a quick look at what’s going on:
.excerpt-container {
float: left;
padding: 2em;
position: relative;
width: 100%;
}
.excerpt {
height: 16em;
}
.excerpt_name_article-1,
.page-1 .article-flow-region {
-webkit-flow-from: article-1;
}
.article-content_for_article-1 {
-webkit-flow-into: article-1;
}
The regions pattern is comprised of at least three components: a beginning; an ending; and a source. Using CSS, we’re able to define specific elements that should be available for the content to flow through. If magazine-style layouts are something you’re interested in learning more about (and you should be), be sure to check out the great work Adobe has been doing.
Looking forward, and backward
As designers, builders, and consumers of the web, we share a desire to see the usability and enjoyability of websites continue to rise. We are incredibly lucky to be working in a time when a three-month-old website can be laughably outdated. Our goal ought to be to improve upon both the weaknesses and the strengths of the web platform. We seek not only smoother transitions and larger canvases, but fine-grained addressability. Our URLs should point directly and unambiguously to specific content elements, be they pages, sections, paragraphs or words. Moreover, off-screen design patterns are essential to accommodating and empowering the multitude of devices we use to access the web. We should express the desire that interpage links take advantage of the CSS transitions which have been put to such good effect in every other aspect of our designs. Transitions aren’t just nice to have, they’re table stakes in the highly competitive world of native applications.
The tools and technologies we have right now allow us to create smart, beautiful, useful webpages. With a little help, we can begin removing the seams and sutures that bind the web to an earlier, less sophisticated generation. |

Redesigning the Media Query |
Responsive web design is showing us that designing content is more important than designing containers. But if you’ve given RWD a serious try, you know that shifting your focus from the container is surprisingly hard to do. There are many factors and
instincts working against you, and one culprit is a perpetrator you’d least suspect.
The media query is the ringmaster of responsive design. It lets us establish the rules of the game and gives us what we need most: control. However, like some kind of evil double agent, the media query is actually working against you.
Its very nature diverts your attention away from content and forces you to focus on the container.
The very act of choosing a media query value means choosing a screen size.
Look at the history of the media query—it’s always been about the container. Values like screen, print, handheld and tv don’t have anything to do with content. The modern media query lets us choose screen dimensions, which is great because it makes RWD possible. But it’s still the act of choosing something that is completely unpredictable.
Content should dictate our breakpoints, not the container. In order to get our focus back to the only thing that matters, we need a reengineered media query—one that frees us from thinking about screen dimensions. A media query that works for your content, not the window. Fortunately, Sass 3.2 is ready and willing to take on this challenge.
Thinking in Columns
Fluid grids never clicked for me. I feel so disoriented and confused by their squishiness. Responsive design demands their use though, right?
I was ready to surrender until I found a grid that turned my world upright again. The Frameless Grid by Joni Korpi demonstrates that column and gutter sizes can stay fixed. As the screen size changes, you simply add or remove columns to accommodate. This made sense to me and armed with this concept I was able to give Sass the first component it needs to rewrite the media query: fixed column and gutter size variables.
$grid-column: 60px;
$grid-gutter: 20px;
We’re going to want some resolution independence too, so let’s create a function that converts those nasty pixel values into ems.
@function em($px, $base: $base-font-size) {
@return ($px / $base) * 1em;
}
We now have the components needed to figure out the width of multiple columns in ems. Let’s put them together in a function that will take any number of columns and return the fixed width value of their size.
@function fixed($col) {
@return $col * em($grid-column + $grid-gutter)
}
With the math in place we can now write a mixin that takes a column count as a parameter, then generates the perfect media query necessary to fit that number of columns on the screen. We can also build in some left and right margin for our layout by adding an additional gutter value (remembering that we already have one gutter built into our fixed function).
@mixin breakpoint($min) {
@media (min-width: fixed($min) + em($grid-gutter)) {
@content
}
}
And, just like that, we’ve rewritten the media query. Instead of picking a minimum screen size for our layout, we can simply determine the number of columns needed. Let’s add a wrapper class so that we can center our content on the screen.
@mixin breakpoint($min) {
@media (min-width: fixed($min) + em($grid-gutter)) {
.wrapper {
width: fixed($min) - em($grid-gutter);
margin-left: auto; margin-right: auto;
}
@content
}
}
Designing content with a column count gives us nice, easy, whole numbers to work with. Sizing content, sidebars or widgets is now as simple as specifying a single-digit number.
@include breakpoint(8) {
.main { width: fixed(5); }
.sidebar { width: fixed(3); }
}
Those four lines of Sass just created a responsive layout for us. When the screen is big enough to fit eight columns, it will trigger a fixed width layout. And give widths to our main content and sidebar. The following is the outputted CSS…
@media (min-width: 41.25em) {
.wrapper {
width: 38.75em;
margin-left: auto; margin-right: auto;
}
.main { width: 25em; }
.sidebar { width: 15em; }
}
Demo
I’ve created a Codepen demo that demonstrates what we’ve covered so far. I’ve added to the demo some grid classes based on Griddle by Nicolas Gallagher to create a floatless layout. I’ve also added a CSS gradient overlay to help you visualize columns. Try changing the column variable sizes or the breakpoint includes to see how the layout reacts to different screen sizes.
Responsive Images
Responsive images are a serious problem, but I’m excited to see the community talk so passionately about a solution. Now, there are some excellent stopgaps while we wait for something official, but these solutions require you to mirror your breakpoints in JavaScript or HTML. This poses a serious problem for my Sass-generated media queries, because I have no idea what the real values of my breakpoints are anymore. For responsive images to work, JavaScript needs to recognize which media query is active so that proper images can be loaded for that layout.
What I need is a way to label my breakpoints. Fortunately, people much smarter than I have figured this out. Jeremy Keith devised a labeling method by using CSS-generated content as the storage method for breakpoint labels. We can use this technique in our breakpoint mixin by passing a label as another argument.
@include breakpoint(8, 'desktop') { /* styles */ }
Sass can take that label and use it when writing the corresponding media query. We just need to slightly modify our breakpoint mixin.
@mixin breakpoint($min, $label) {
@media (min-width: fixed($min) + em($grid-gutter)) {
// label our mq with CSS generated content
body::before { content: $label; display: none; }
.wrapper {
width: fixed($min) - em($grid-gutter);
margin-left: auto; margin-right: auto;
}
@content
}
}
This allows us to label our breakpoints with a user-friendly string. Now that our media queries are defined and labeled, we just need JavaScript to step in and read which label is active.
// get css generated label for active media query
var label = getComputedStyle(document.body, '::before')['content'];
JavaScript now knows which layout is active by reading the label in the current media query—we just need to match that label to an image. I prefer to store references to different image sizes as data attributes on my image tag.
<img class="responsive-image" data-mobile="mobile.jpg" data-desktop="desktop.jpg" />
<noscript><img src="desktop.jpg" /></noscript>
These data attributes have names that match the labels set in my CSS. So while there is some duplication going on, setting a keyword like ‘tablet’ in two places is much easier than hardcoding media query values. With matching labels in CSS and HTML our script can marry the two and load the right sized image for our layout.
// get css generated label for active media query
var label = getComputedStyle(document.body, '::before')['content'];
// select image
var $image = $('.responsive-image');
// create source from data attribute
$image.attr('src', $image.data(label));
Demo
With some slight additions to our previous Codepen demo you can see this responsive image technique in action. While the above JavaScript will work it is not nearly robust enough for production so the demo uses a jQuery plugin that can accomodate multiple images, reloading on screen resize and fallbacks if something doesn’t match up.
Creating a Framework
This media query mixin and responsive image JavaScript are the center piece of a front end framework I use to develop websites. It’s a fluid, mobile first foundation that uses the breakpoint mixin to structure fixed width layouts for tablet and desktop. Significant effort was focused on making this framework completely cross-browser. For example, one of the problems with using media queries is that essential desktop structure code ends up being hidden from legacy Internet Explorer. Respond.js is an excellent polyfill, but if you’re comfortable serving a single desktop layout to older IE, we don’t need JavaScript. We simply need to capture layout code outside of a media query and sandbox it under an IE only class name.
// set IE fallback layout to 8 columns
$ie-support = 8;
// inside of our breakpoint mixin (but outside the media query)
@if ($ie-support and $min <= $ie-support) {
.lt-ie9 { @content; }
}
Perspective Regained
Thinking in columns means you are thinking about content layout. How big of a screen do you need for 12 columns? Who cares? Having Sass write media queries means you can use intuitive numbers for content layout. A fixed grid means more layout control and less edge cases to test than a fluid grid. Using CSS labels for activating responsive images means you don’t have to duplicate breakpoints across separations of concern.
It’s a harmonious blend of approaches that gives us something we need—responsive design that feels intuitive. And design that, from the very outset, focuses on what matters most. Just like our kindergarten teachers taught us: It’s what’s inside that counts. |

Design Systems |
The most important part of responsive web design is that, no matter what the viewport width, the content is accessible in an optimum display. The best responsive designs are those that allow you to go from one optimised display to another, but with the feeling that these experiences are part of a greater product whole.
Responsive design: where we’ve been going wrong
Responsive web design was a shock to my web designer system. Those of us who had already been designing sites for mobile probably had the biggest leap to make. We might have been detecting user agents in order to deliver a mobile-specific site, or using the slightly more familiar Bushido technique to deliver sites optimised for device type and viewport size, but either way our focus was on devices. A site was optimised for either a mobile phone or a desktop.
Responsive web design brought us back to pre-table layout fluid sites that expanded or contracted to fit the viewport. This was a big difference to get our heads around when we were so used to designing for fixed-width layouts. Suddenly, an element could be any width or, at least, we needed to consider its maximum and minimum widths. Pixel perfection, while pretty, became wholly unrealistic, and a whole load of designers who prided themselves in detailed and precise designs got a bit scared.
Hanging on to our previous processes and typical deliverables led us to continue to optimise our sites for particular devices and provide pixel-perfect mockups for those device widths.
With all this we were concentrating on devices, not content, deliverables and not process, and making assumptions about users and their devices based on nothing but the width of the viewport.
I don’t think this is a crime, I think it was inevitable.
We can be up to date with our principles and ideals, but it’s never as easy in practice. That’s why it’s more important than ever to share our successful techniques and processes. Let’s drag each other into modern web design.
Design systems: the principles
What are design systems?
A visual design system is built out of the core components of typography, layout, shape or form, and colour. When considering the design of a whole product, a design system should also include patterns in user flow, content strategy, copy, and tone of voice. These concepts, design decisions or rules, created around the core components are used consistently across your product to create a cohesive feel, whether it’s from one element to another, page to page, or viewport width to viewport width.
Responsive design is one of the most important considerations in the components of a design system. For each component, you must decide what will unite the design across the viewports to maintain that consistent feel, and what parts of the design will differentiate in order to provide a flexible and optimal experience for different viewport sizes.
Components you might keep the same across viewports
typeface
base unit
colour
shape/form
Components you might differentiate across viewports
grids
layout
font size
measure (line length)
leading (line height)
Content: it must always be the same
The focus of a design system is the optimum display of content. As Mark Boulton put it, designing “content out, not canvas in.” Chris Armstrong puts the emphasis on not designing for viewports but for content – “we need to build on what we do know: content.” In order to do this, we must share the same content across all devices and focus on how best to display and represent content through design system components.
The practical: core visual components
Typography first
When you work with a lot of text content, typography is the easiest way to set the visual tone of the design across all viewport widths. It’s likely that you’ll choose one or two typefaces to use across the whole system, but you might change the most legible font size, balanced with the most comfortable measure, as the viewport width changes.
Where typography meets layout
The unit on which you choose to base the grid and layout design, font sizes and leading could be based on the typeface, an optimal reading size, or something more arbitrary. Sometimes I’ll choose a unit based on multiples of ten because it makes the maths in the CSS easier. Tim Brown suggests trying a modular scale. Chris Armstrong suggests basing it on your ideal measure, or the width of a fixed item of content such as an ad unit.
Grids and layouts
Sensible grid design can be a flexible yet solid foundation for your design system layout component. But you must be wary in responsive design that a grid might not work across all widths: even four columns could make for very cramped content and one-word measures on smaller screens.
Maybe the grid columns are something you differentiate across widths, but you can keep the concept of the grid consistent. If the content has blocks in groups of three, you might decide on a three-column grid which folds down to one column for narrow viewports. If the grid focuses on the idea of symmetry and has a four-column grid on larger viewports, it might fold down to two columns for narrower viewports. These consistencies may seem subtle, not at all obvious to many except the designer, but it’s all these little constants and patterns across the whole of the design system that makes design decisions easier to make (as they adhere to the guiding concepts of your system), and give the product a uniform feel no matter what the device.
Shape or form
The shape or form components are concepts you already use in fixed-width web design for a strong, consistent look and feel.
Since CSS border-radius became widely supported by browsers, a lot of designs feature circle themes. These are very distinctive and can be used across viewport widths giving them the same united feel, even if they’re not used in the same way. This could also apply to border styles, consistent shadows and any number of decorative details and textures. These are the elements that make up the shape or form of a design system.
Colour
Colour is the most basic way to reinforce a brand and unite experiences across viewports. The same hex colour used system-wide is instantly recognisable, no matter what the viewport width.
The process
While using a design system isn’t necessarily attached to any particular process, it does lend itself to some process ideals.
Detaching design considerations from viewport widths
A design system allows you to focus separately on the components that make up the system, disconnecting the look and feel from the layout. This helps prevent us getting stuck in the rut of the Apple breakpoints (brilliantly coined by Simon Foster) of mobile, tablet and desktop. It also forces us to design for variation in viewport experiences side by side, not one after the other.
Design in the browser
I can’t start off designing in the browser – it just doesn’t seem to bring out my creative side (and I’m incredibly envious of you if you can; I just have to start on paper) – but static mock-ups aren’t the only alternative. Style guides and style tiles are perfect for expressing the concepts of your design system. Pattern libraries could also work well.
Mock-ups and breakpoints
At some point, whether it’s to test your system ideas, or because a client needs help visualising how your system might work, you may end up producing some static mock-ups. It’s not the end of the world, but you must ensure that these consider all the viewports, not just those of the iDevices, or even the devices currently on the market. You need to decide the breakpoints where the states of your design change. The blocks within your content will always have optimum points for their display (based on their hierarchy, density, width, or type of interaction) and so your breakpoints should be based around these points.
These are probably the ideal points at which to produce static mockups; treat them as snapshots. They’re not necessarily mock-ups, so much as a way of capturing how your design system would be interpreted when frozen at that particular viewport width.
The future
Creating design systems will give us the flexibility we need for working with the unknown devices of the future. It may be a change in process, but it shouldn’t be too much of a difference in thinking. The pioneers in responsive design have a hard job. Some of these problems may have already been solved in other technologies or industries, but it’s up to the pioneers to find those connections and help us formulate solutions and standards that will make responsive design the best it can possibly be. We need to keep experimenting and communicating, particularly in the area of design, as good user experiences are the true sign of whether our products are a success. |

Using Questionnaires for Design Research |
How do you ask the right questions?
In this article, I share a bunch of tips and practical advice on how to write and use your own surveys for design research.
I’m an audience researcher – I’m not a designer or developer. I’ve spent much of the last thirteen years working with audience data both in creative agencies and on the client-side. I’m also a member of the Market Research Society. I run user surveys and undertake user research for our clients at the design studio I run with my husband – Mark Boulton Design.
So let’s get started!
Who are you designing for?
Good web designers and developers appreciate the importance of understanding the audience they are designing or building a website or app for. I’m assuming that because you are reading a quality publication like 24 ways that you fall into this category, and so I won’t begin this article with a lecture.
Suffice it to say, it’s a good idea to involve research of some sort during the life cycle of every project you undertake. I don’t just mean visual or competitor research, which of course is also very important. I mean looking at or finding your own audience or user data. Whether that be auditing existing data or research available from the client, carrying out user interviews, A/B testing, or conducting a simple questionnaire with users, any research is better than none. If you create personas as a design tool, they should always be based on research, so you will need to have plenty of data to hand for that.
Where do I start?
In the initial kick-off stages of a project, it’s a good idea to start by asking your client (when working in-house you still have a client – you might even be the client) what research or audience data they have available. Some will have loads – analytics, surveys, focus groups and insights – from talking to customers. Some won’t have much at all and you’ll be hard pressed to find out much about the audience. It’s best to review existing research first without rushing headlong into doing new research. Get a picture of what the data tells you and perhaps get this into a document – who, what, why and how are they using this website or app? What gaps are there in existing research? What else do you need to know? Then you can decide what else you need to do to plug these gaps. Think about the information first before deciding on the methodology. The rest of my article talks mostly about running self-completion online surveys. You can of course do face-to-face surveys, self-completion written questionnaires or phone polls, but I won’t cover those here. That’s for another article.
Why run a survey?
Surveys are great for getting a broad picture of your audience. As long as they are designed carefully, you can create an overview of them, how they use the site and their opinions of it, with an idea of which parts of this picture are more important than others. By using a limited amount of open-ended questions, you can also get some more qualitative feedback or insights on your website or app. The clients we work with surprisingly often don’t have much in the way of audience research available, even basic analytics, so I will often suggest running a short survey, just to create a picture of who is out there.
OK, what should I do first?
Before you rush into writing questions, stop and think about what you’re trying to find out. Remember being in school when you studied science and you had to propose a hypothesis? This could be a starting point – something to prove or disprove. Or, even better, write a research brief. It doesn’t have to be long; it can be just a sentence that encapsulates what you’re trying to do, like a good creative brief. For the purposes of this article, I created a short, slightly silly survey on Christmas and beliefs in Father Christmas.
My research brief was:
To find out more about people’s beliefs about Father Christmas and their experiences of Christmas.
Inevitably, as you start thinking of what questions to ask, you will find that you go off at tangents or your client will want you to add in everything but the kitchen sink. In order for your questionnaire not to get too long and lose focus, you could write lists of what it is and what it’s not. This is how I’d apply it to my Christmas questionnaire example:
What it is about
How people communicate with Father Christmas
If someone’s background has affected their likelihood of believing in Father Christmas
What it is not about
What colour to change Father Christmas’s coat to
Father Christmas’s elves
Let’s get down to business: the questions.
Kinds of questions
There are two basic kinds of questions: open-ended and closed. Closed questions limit answers by giving the respondent a number of predefined lists of options to choose from. Typically, these are multiple-choice questions with a list of responses. You can either select one or tick all that apply. Another useful type of closed question I often use is a rating scale, where a respondent can assess a situation along a continuum of values. These can also be useful as a measure of advocacy or strength of feeling about something. There is a standard measure called the Net Promoter score, which measures how likely someone is to recommend your product or service to a friend or acquaintance. It’s a useful benchmark as you can compare your scores to others in a similar sector.
Open-ended questions often take the form of a statement which requires a response. Generally, respondents are given a text box to fill in. It’s useful to limit this in some way so that people have an idea of how long the expected response should be; for example, a single line for an email address (Q18), or a larger text area for a longer response (Q6).
If you plan to send your survey out to a large number of people, I would suggest using mostly closed questions, unless you want to spend a long time wading through comments and hand-coded responses. I’d always advise adding a general request at the end of a survey (‘Is there anything else you’d like to tell us?’). You’d be surprised how many interesting and insightful comments people will add.
There are times when it’s better to provide an open-ended text box rather than a predefined list makes assumptions about your audience’s groupings. For example, we ran a short survey for our Gridset beta testers and rather than assume we knew who they were, we decided to ask an open-ended question: “What is your current job title?”
The analysis took quite a bit longer than responses using a predefined list, but it meant that we were able to make sure we didn’t miss anyone. And next time we run a survey for Gridset, I can use the responses gathered from this survey to help create a predefined list to make analysis easier.
What to ask
The questions to ask depend on what you want to know, but your brief and lists of what the survey is and isn’t should help here. I always ask the design team and client to give me ideas of what they are interested in finding out, and combine this with a mix of new and standard questions I have used in other surveys. I find Survey Monkey’s question bank a very useful source of example questions and help with tricky wording.
I always include simple demographics so I can compare my results to the population at large or internet users as a whole – just going on age, gender and location can be quite illuminating. For example, with the Christmas survey, I can see that the respondents were typical of the online design and dev community, mainly young and male.
If appropriate, I add questions on disability, ethnic background, religion and community of interest. Questions about ethnicity, religion, sexual preference, disability and other sensitive subjects can feel awkward and difficult to ask. This is not a good reason to not ask them. Perhaps you’re working for a public sector client, like a local council, so it’s likely you will need to consider groups of people who maybe under-represented, who may have differing views to others, or who you need to look at specifically as a subset.
How to ask
Although they may seem clunky and wordy, it’s often best to use the census wording or professional body wording for such demographic questions. For example, I used the UK census 2011 wording for Wales on my Christmas questionnaire in my questions on religion [PDF] (Q16) and ethnicity [PDF] (Q17). I had to adapt them slightly for the Survey Monkey format – self-completion online, rather than pen and paper – which is why “White Welsh” came up as the first option for the ethnicity question. For similar questions for US audiences, try the Census Bureau website.
When conducting a survey for a project that has a global audience, you need to consider who your primary audience is. For example, I recently created a questionnaire for a global news website. A large proportion of its audience is based in the USA, so I was careful to word things in a way Americans would find familiar. I used the US ethnic background census question wording and options, and looked at data for US competitor news websites to decide which to include.
You should also consider people whose first language isn’t English. Working as an audience researcher at BBC Wales, every survey we did was bilingual. I’ve also recently run a user survey in Arabic using Google Forms. During this project, we found that while Survey Monkey supports different languages, including Arabic, the text ran left to right with no option to change it to right to left – an essential when it comes to reading Arabic! If research is a deliverable in a client project, and you know you’ll need to conduct it in a foreign language, always build in extra time for translation at both the questionnaire design and analysis stages. Make sure you also allow for plenty of checks. In this case we had to change to Google Forms after initially creating our survey with Survey Monkey to get the functionality we needed.
Look and feel
Think about the survey as another way your audience will experience your brand. Take care getting the tone of voice right. There are plenty of great articles and books out there about tone of voice – try Letting Go of the Words by Ginny Redish for starters, or Brand Language by Liz Doig. The basic rule of thumb is to sound like a human, and use clear and friendly language. If, like me, you are lucky enough to work with journalists or copy editors, you should ask for their help, particularly in the preamble, linking text and closing statements. I find it helpful to break my questions down into sections and to have a page for each. I then have an introductory piece of text for each section to guide the respondent through the survey.
You should also make sure you check with your designers how your survey looks – use a company logo and branding, and make the typography legible. Many survey apps like Survey Monkey and Google Forms have a progress bar. This is helpful for users to see how far through your survey they are. I generally time the survey and give an indication in the preamble: “This survey will only take five minutes of your time.”
You also need to think about how you will technically serve the questionnaire. For example, will it be via email, social media, a pop-up or lightbox on your website, or (not recommended but possible) in an ad space?
Ethical considerations
Something else to think about are any local laws that govern how you collect and store data, such as the Data Protection Act in the UK. As a member of the Market Research Society, I am also obliged to consider its guidelines, but even if you’re not, it’s always a good idea to deal with personal data ethically.
If you collect personal data that can identify individuals, you must ask their permission to share it with others, and store it securely for no longer than two years. If you want to contact people afterwards, you must ask for their permission. If you ask for email addresses, as I did in question 18, you have a ready-made sample for a further survey, interviews or focus groups. Remember, you shouldn’t survey people under sixteen years old without the permission of their parents or legal guardians, so if you know your website is likely to be used by children, you must ask for verification of age early on, and your survey should close someone answers that they are under sixteen. The ESOMAR guidelines for online research [PDF] are well worth reading, as they go into detail about such issues, as well as privacy guidelines – using cookies, storing IP addresses, and so on.
Tools
Unless you work in-house and have proprietary software, or at a market research agency and you’re using specialist software such as Snap or IBM SPSS Statistics (previously just SPSS), you will need to use a good tool to run your survey, collect your responses and, ideally, help with the analysis. I like Survey Monkey because of the question bank and analysis tools. The software graphs your results and does simple cross-tabbing and filtering. What this means is you can slice the data in more interesting ways and delve a bit deeper. For example, in the Gridset questionnaire I mentioned earlier, I cross-tabbed responses to questions against whether a person worked in-house, for an agency or as a freelancer.
Other well known online tools that I also use from time to time are Wufoo and Google Forms. Smart Surveys is a similar service to Survey Monkey and it’s used by many leading brands in the UK. Snap Surveys mentioned above is a well-established player in the market research scene, used a lot for face-to-face surveys and also on tablets and smartphones.
Analysis
Analysis is often overlooked but is as important as the design of the questionnaire. Don’t just rely on looking at the summary report and charts generated as standard by your form or survey software. Spend time with your data. Spend at least a week now and then if you can, looking at the data. Keep coming back to it and tweaking or cutting it a different way to see if there are any different pictures. Slice it up in different ways to reveal new insights. Here is the data from my dummy survey (apart from the open-ended responses).
For open-ended questions, you can analyse collaboratively. Print and cut out the open-ended responses and do a cluster analysis or affinity sort with a colleague.
Discussing the comments helps you to understand them. You will also find the design team are more likely to buy into the research as they have uncovered the insights for themselves. Always make sure to treat open-ended responses sensitively and don’t share anything publicly in a way that identifies the respondent.
Write a report
Never hand over a dataset to your client without a summary of the findings. Data on its own can be skewed to suit the reader’s needs, and not everyone is able to find the story in a dataset. Even if it’s not a deliverable, it’s always a good idea to capture your findings in a report of some sort. Use graphs sparingly to show really interesting things or to aid the reader’s understanding. I have written a quick dummy report using the data from the Christmas questionnaire so you can see how it’s done.
I highly recommend Brian Suda’s book A Practical Guide to Designing with Data for tips on how to present data effectively, but that’s a subject that benefits a whole article (indeed book) in itself.
I am not a designer. I am a researcher, so I never write design recommendations in a report unless they have been talked about or suggested by the designers I work with. More often, I write up the results and we talk about them and what impact they have on the project or design. Often they lead to more questions or further research.
So that’s it: a brief introduction to using questionnaires for design research. Here’s a quick summary to remind you what I have talked about, and a list of resources if you’re interested in reading further.
Top 10 things to remember when using questionnaires for design research:
Start by auditing existing research to identify gaps in data.
Write a research brief. Work out exactly what you’re trying to find out – what is the survey about, and what is it not about?
The two basic kinds of questions are open-ended and closed.
Closed questions limit responses by giving the respondent a number of predefined lists of options to choose from (multiple choice, rating scales, and so on).
Open-ended questions are often in the form of a statement which requires a response. Always ask one at the end of a questionnaire.
Always include simple demographics to enable you to compare your sample against the population in general.
It’s best to use official census or professional body wording for questions on ethnicity, disability and religion.
Be sure to think carefully about your tone of voice and the look of your questionnaire.
Pay attention to guidelines and laws on storing personal data, cookies and privacy.
Invest plenty of time in analysis and report writing. Don’t just look at the obvious – dig deep for more interesting insights.

Giving Content Priority with CSS3 Grid Layout |
Browser support for many of the modules that are part of CSS3 have enabled us to use CSS for many of the things we used to have to use images for. The rise of mobile browsers and the concept of responsive web design has given us a whole new way of looking at design for the web. However, when it comes to layout, we haven’t moved very far at all. We have talked for years about separating our content and source order from the presentation of that content, yet most of us have had to make decisions on source order in order to get a certain visual layout.
Owing to some interesting specifications making their way through the W3C process at the moment, though, there is hope of change on the horizon. In this article I’m going to look at one CSS module, the CSS3 grid layout module, that enables us to define a grid and place elements on to it. This article comprises a practical demonstration of the basics of grid layout, and also a discussion of one way in which we can start thinking of content in a more adaptive way.
Before we get started, it is important to note that, at the time of writing, these examples work only in Internet Explorer 10. CSS3 grid layout is a module created by Microsoft, and implemented using the -ms prefix in IE10. My examples will all use the -ms prefix, and not include other prefixes simply because this is such an early stage specification, and by the time there are implementations in other browsers there may be inconsistencies. The implementation I describe today may well change, but is also there for your feedback.
If you don’t have access to IE10, then one way to view and test these examples is by signing up for an account with Browserstack – the free trial would give you time to have a look. I have also included screenshots of all relevant stages in creating the examples.
What is CSS3 grid layout?
CSS3 grid layout aims to let developers divide up a design into a grid and place content on to that grid. Rather than trying to fabricate a grid from floats, you can declare an actual grid on a container element and then use that to position the elements inside. Most importantly, the source order of those elements does not matter.
Declaring a grid
We declare a grid using a new value for the display property: display: grid. As we are using the IE10 implementation here, we need to prefix that value: display: -ms-grid;.
Once we have declared our grid, we set up the columns and rows using the grid-columns and grid-rows properties.
.wrapper {
display: -ms-grid;
-ms-grid-columns: 200px 20px auto 20px 200px;
-ms-grid-rows: auto 1fr;
}
In the above example, I have declared a grid on the .wrapper element. I have used the grid-columns property to create a grid with a 200 pixel-wide column, a 20 pixel gutter, a flexible width auto column that will stretch to fill the available space, another 20 pixel-wide gutter and a final 200 pixel sidebar: a flexible width layout with two fixed width sidebars. Using the grid-rows property I have created two rows: the first is set to auto so it will stretch to fill whatever I put into it; the second row is set to 1fr, a new value used in grids that means one fraction unit. In this case, one fraction unit of the available space, effectively whatever space is left.
Positioning items on the grid
Now I have a simple grid, I can pop items on to it. If I have a <div> with a class of .main that I want to place into the second row, and the flexible column set to auto I would use the following CSS:
.content {
-ms-grid-column: 3;
-ms-grid-row: 2;
-ms-grid-row-span: 1;
}
If you are old-school, you may already have realised that we are essentially creating an HTML table-like layout structure using CSS. I found the concept of a table the most helpful way to think about the grid layout module when trying to work out how to place elements.
Creating grid systems
As soon as I started to play with CSS3 grid layout, I wanted to see if I could use it to replicate a flexible grid system like this fluid 16-column 960 grid system.
I started out by defining a grid on my wrapper element, using fractions to make this grid fluid.
.wrapper {
width: 90%;
margin: 0 auto 0 auto;
display: -ms-grid;
-ms-grid-columns: 1fr (4.25fr 1fr)[16];
-ms-grid-rows: (auto 20px)[24];
}
Like the 960 grid system I was using as an example, my grid starts with a gutter, followed by the first actual column, plus another gutter repeated sixteen times. What this means is that if I want to span two columns, as far as the grid layout module is concerned that is actually three columns: two wide columns, plus one gutter. So this needs to be accounted for when positioning items.
I created a CSS class for each positioning option: column position; rows position; and column span. For example:
.grid1 {-ms-grid-column: 2;} /* applying this class positions an item in the first column (the gutter is column 1) */
.grid2 {-ms-grid-column: 4;} /* 2nd column - gutter|column 1|gutter */
.grid3 {-ms-grid-column: 6;} /* 3rd column - gutter|column 1|gutter|column2|gutter */
.row1 {-ms-grid-row:1;}
.row2 {-ms-grid-row:3;}
.row3 {-ms-grid-row:5;}
.colspan1 {-ms-grid-column-span:1;}
.colspan2 {-ms-grid-column-span:3;}
.colspan3 {-ms-grid-column-span:5;}
I could then add multiple classes to each element to set the position on on the grid.
This then gives me a replica of the fluid grid using CSS3 grid layout. To see this working fire up IE10 and view Example 1.
This works, but…
This worked, but isn’t ideal. I considered not showing this stage of my experiment – however, I think it clearly shows how the grid layout module works and is a useful starting point. That said, it’s not an approach I would take in production. First, we have to add classes to our markup that tie an element to a position on the grid. This might not be too much of a problem if we are always going to maintain the sixteen-column grid, though, as I will show you that the real power of the grid layout module appears once you start to redefine the grid, using different grids based on media queries. If you drop to a six-column layout for small screens, positioning items into column 16 makes no sense any more.
Calculating grid position using LESS
As we’ve seen, if you want to use a grid with main columns and gutters, you have to take into account the spacing between columns as well as the actual columns. This means we have to do some calculating every time we place an item on the grid. In my example above I got around this by creating a CSS class for each position, allowing me to think in sixteen rather than thirty-two columns. But by using a CSS preprocessor, I can avoid using all the classes yet still think in main columns.
I’m using LESS for my example. My simple grid framework consists of one simple mixin.
.position(@column,@row,@colspan,@rowspan) {
-ms-grid-column: @column*2;
-ms-grid-row: @row*2-1;
-ms-grid-column-span: @colspan*2-1;
-ms-grid-row-span: @rowspan*2-1;
}
My mixin takes four parameters: column; row; colspan; and rowspan. So if I wanted to place an item on column four, row three, spanning two columns and one row, I would write the following CSS:
.box {
.position(4,3,2,1);
}
The mixin would return:
.box {
-ms-grid-column: 8;
-ms-grid-row: 5;
-ms-grid-column-span: 3;
-ms-grid-row-span: 1;
}
This saves me some typing and some maths. I could also add other prefixed values into my mixin as other browsers started to add support.
We can see this in action creating a new grid. Instead of adding multiple classes to each element, I can add one class; that class uses the mixin to create the position. I have also played around with row spans using my mixin and you can see we end up with a quite complicated arrangement of boxes. Have a look at example two in IE10. I’ve used the JavaScript LESS parser so that you can view the actual LESS that I use. Note that I have needed to escape the -ms prefixed properties with ~"" to get LESS to accept them.
This is looking better. I don’t have direct positioning information on each element in the markup, just a class name – I’ve used grid(x), but it could be something far more semantic. We can now take the example a step further and redefine the grid based on screen width.
Media queries and the grid
This example uses exactly the same markup as the previous example. However, we are now using media queries to detect screen width and redefine the grid using a different number of columns depending on that width.
I start out with a six-column grid, defining that on .wrapper, then setting where the different items sit on this grid:
.wrapper {
width: 90%;
margin: 0 auto 0 auto;
display: ~"-ms-grid"; /* escaped for the LESS parser */
-ms-grid-columns: ~"1fr (4.25fr 1fr)[6]"; /* escaped for the LESS parser */
-ms-grid-rows: ~"(auto 20px)[40]"; /* escaped for the LESS parser */
}
.grid1 { .position(1,1,1,1); }
.grid2 { .position(2,1,1,1); }
/* ... see example for all declarations ... */
Using media queries, I redefine the grid to nine columns when we hit a minimum width of 700 pixels.
@media only screen and (min-width: 700px) {
.wrapper {
-ms-grid-columns: ~"1fr (4.25fr 1fr)[9]";
-ms-grid-rows: ~"(auto 20px)[50]";
}
.grid1 { .position(1,1,1,1); }
.grid2 { .position(2,1,1,1); }
/* ... */
}
Finally, we redefine the grid for 960 pixels, back to the sixteen-column grid we started out with.
@media only screen and (min-width: 940px) {
.wrapper {
-ms-grid-columns:~" 1fr (4.25fr 1fr)[16]";
-ms-grid-rows:~" (auto 20px)[24]";
}
.grid1 { .position(1,1,1,1); }
.grid2 { .position(2,1,1,1); }
/* ... */
}
If you view example three in Internet Explorer 10 you can see how the items reflow to fit the window size. You can also see, looking at the final set of blocks, that source order doesn’t matter. You can pick up a block from anywhere and place it in any position on the grid.
Laying out a simple website
So far, like a toddler on Christmas Day, we’ve been playing with boxes rather than thinking about what might be in them. So let’s take a quick look at a more realistic layout, in order to see why the CSS3 grid layout module can be really useful. At this time of year, I am very excited to get out of storage my collection of odd nativity sets, prompting my family to suggest I might want to open a museum. Should I ever do so, I’ll need a website, and here is an example layout.
As I am using CSS3 grid layout, I can order my source in a logical manner. In this example my document is as follows, though these elements could be in any order I please:
<div class="wrapper">
<div class="welcome">
...
</div>
<article class="main">
...
</article>
<div class="info">
...
</div>
<div class="ads">
...
</div>
</div>
For wide viewports I can use grid layout to create a sidebar, with the important information about opening times on the top righ,t with the ads displayed below it. This creates the layout shown in the screenshot above.
@media only screen and (min-width: 940px) {
.wrapper {
-ms-grid-columns:~" 1fr (4.25fr 1fr)[16]";
-ms-grid-rows:~" (auto 20px)[24]";
}
.welcome {
.position(1,1,12,1);
padding: 0 5% 0 0;
}
.info {
.position(13,1,4,1);
border: 0;
padding:0;
}
.main {
.position(1,2,12,1);
padding: 0 5% 0 0;
}
.ads {
.position(13,2,4,1);
display: block;
margin-left: 0;
}
}
In a floated layout, a sidebar like this often ends up being placed under the main content at smaller screen widths. For my situation this is less than ideal. I want the important information about opening times to end up above the main article, and to push the ads below it. With grid layout I can easily achieve this at the smallest width .info ends up in row two and .ads in row five with the article between.
.wrapper {
display: ~"-ms-grid";
-ms-grid-columns: ~"1fr (4.25fr 1fr)[4]";
-ms-grid-rows: ~"(auto 20px)[40]";
}
.welcome {
.position(1,1,4,1);
}
.info {
.position(1,2,4,1);
border: 4px solid #fff;
padding: 10px;
}
.content {
.position(1,3,4,5);
}
.main {
.position(1,3,4,1);
}
.ads {
.position(1,4,4,1);
}
Finally, as an extra tweak I add in a breakpoint at 600 pixels and nest a second grid on the ads area, arranging those three images into a row when they sit below the article at a screen width wider than the very narrow mobile width but still too narrow to support a sidebar.
@media only screen and (min-width: 600px) {
.ads {
display: ~"-ms-grid";
-ms-grid-columns: ~"20px 1fr 20px 1fr 20px 1fr";
-ms-grid-rows: ~"1fr";
margin-left: -20px;
}
.ad:nth-child(1) {
.position(1,1,1,1);
}
.ad:nth-child(2) {
.position(2,1,1,1);
}
.ad:nth-child(3) {
.position(3,1,1,1);
}
}
View example four in Internet Explorer 10.
This is a very simple example to show how we can use CSS grid layout without needing to add a lot of classes to our document. It also demonstrates how we can mainpulate the content depending on the context in which the user is viewing it.
Layout, source order and the idea of content priority
CSS3 grid layout isn’t the only module that starts to move us away from the issue of visual layout being linked to source order. However, with good support in Internet Explorer 10, it is a nice way to start looking at how this might work. If you look at the grid layout module as something to be used in conjunction with the flexible box layout module and the very interesting CSS regions and exclusions specifications, we have, tantalizingly on the horizon, a powerful set of tools for layout.
I am particularly keen on the potential separation of source order from layout as it dovetails rather neatly into something I spend a lot of time thinking about. As a CMS developer, working on larger scale projects as well as our CMS product Perch, I am interested in how we better enable content editors to create content for the web. In particular, I search for better ways to help them create adaptive content; content that will work in a variety of contexts rather than being tied to one representation of that content.
If the concept of adaptive content is new to you, then Karen McGrane’s presentation Adapting Ourselves to Adaptive Content is the place to start. Karen talks about needing to think of content as chunks, that might be used in many different places, displayed differently depending on context.
I absolutely agree with Karen’s approach to content. We have always attempted to move content editors away from thinking about creating a page and previewing it on the desktop. However at some point content does need to be published as a page, or a collection of content if you prefer, and bits of that content have priority. Particularly in a small screen context, content gets linearized, we can only show so much at a time, and we need to make sure important content rises to the top. In the case of my example, I wanted to ensure that the address information was clearly visible without scrolling around too much. Dropping it with the entire sidebar to the bottom of the page would not have been so helpful, though neither would moving the whole sidebar to the top of the screen so a visitor had to scroll past advertising to get to the article.
If our layout is linked to our source order, then enabling the content editor to make decisions about priority is really hard. Only a system that can do some regeneration of the source order on the server-side – perhaps by way of multiple templates – can allow those kinds of decisions to be made. For larger systems this might be a possibility; for smaller ones, or when using an off-the-shelf CMS, it is less likely to be. Fortunately, any system that allows some form of custom field type can be used to pop a class on to an element, and with CSS grid layout that is all that is needed to be able to target that element and drop it into the right place when the content is viewed, be that on a desktop or a mobile device.
This approach can move us away from forcing editors to think visually. At the moment, I might have to explain to an editor that if a certain piece of content needs to come first when viewed on a mobile device, it needs to be placed in the sidebar area, tying it to a particular layout and design. I have to do this because we have to enforce fairly strict rules around source order to make the mechanics of the responsive design work. If I can instead advise an editor to flag important content as high priority in the CMS, then I can make decisions elsewhere as to how that is displayed, and we can maintain the visual hierarchy across all the different ways content might be rendered.
Why frustrate ourselves with specifications we can’t yet use in production?
The CSS3 grid layout specification is listed under the Exploring section of the list of current work of the CSS Working Group. While discussing a module at this stage might seem a bit pointless if we can’t use it in production work, there is a very real reason for doing so. If those of us who will ultimately be developing sites with these tools find out about them early enough, then we can start to give our feedback to the people responsible for the specification. There is information on the same page about how to get involved with the disussions.
So, if you have a bit of time this holiday season, why not have a play with the CSS3 grid layout module? I have outlined here some of my thoughts on how grid layout and other modules that separate layout from source order can be used in the work that I do. Likewise, wherever in the stack you work, playing with and thinking about new specifications means you can think about how you would use them to enhance your work. Spot a problem? Think that a change to the specification would improve things for a specific use case? Then you have something you could post to www-style to add to the discussion around this module.
All the examples are on CodePen so feel free to play around and fork them. |

Unwrapping the Wii U Browser |
The Wii U was released on 18 November 2012 in the US, and 30 November in the UK. It’s the first eighth generation home console, the first mainstream second-screen device, and it has some really impressive browser specs.
Consoles are not just for games now: they’re marketed as complete entertainment solutions. Internet connectivity and browser functionality have gone from a nice-to-have feature in game consoles to a selling point. In Nintendo’s case, they see it as a challenge to design an experience that’s better than browsing on a desktop.
Let’s make a browser that users can use on a daily basis, something that can really handle everything we’ve come to expect from a browser and do it more naturally.
Sasaki – Iwata Asks on Nintendo.com
With 11% of people using console browsers to visit websites, it’s important to consider these devices right from the start of projects. Browsing the web on a TV or handheld console is a very different experience to browsing on a desktop or a mobile phone, and has many usability implications.
Console browser testing
When I’m testing a console browser, one of the first things I do is run Niels Leenheer’s HTML5 test and Lea Verou’s CSS3 test. I use these benchmarks as a rough comparison of the standards each browser supports.
In October, IE9 came out for the Xbox 360, scoring 120/500 in the HTML5 test and 32% in the CSS3 test. The PS Vita also had an update to its browser in recent weeks, jumping from 58/500 to 243/500 in the HTML5 test, and 32% to 55% in the CSS3 test. Manufacturers have been stepping up their game, trying to make their browsing experiences better.
To give you an idea of how the Wii U currently compares to other devices, here are the test results of the other TV consoles I’ve tested. I’ve written more in-depth notes on TV and portable console browsers separately.
Year of releaseHTML5 scoreCSS3 scoreNotes
Wii U2012258/50048%Runs a Netfront browser (WebKit).
Wii200689/500Wouldn’t runRuns an Opera browser.
PS3200668/50038%Runs a Netfront browser (WebKit).
Xbox 3602005120/50032%A browser for the Xbox (IE9) was only recently released in October 2012. The Kinect provides voice and gesture support. There’s also SmartGlass, a second-screen app for platforms including Android and iOS.
The Wii U browser is Nintendo’s fifth attempt at a console browser. Based on these tests, it’s already looking promising.
Why console browsers used to suck
It takes a lot of system memory to run a good browser, and the problem of older consoles is that they don’t have much memory available. The original Nintendo DS needs a memory expansion pack just to run the browser, because the 4MB it has on board isn’t enough. I noticed that even on newer devices, some sites fail to load because the system runs out of memory.
The Wii came out six years ago with an Opera browser. Still being used today and with such low resources available, the latest browser features can’t reasonably be supported. There’s also pressure to add features such as tabs, and enable gamers to use the browser while a game is paused. Nintendo’s browser team have the advantage of higher specs to play with on their new console (1GB of memory dedicated to games, 1GB for the system), which makes it easier to support the latest standards. But it’s still a challenge to fit everything in.
…even though we have more memory, the amount of memory we can use for the browser is limited compared to a PC, so we’ve worked in ways that efficiently allocates the available memory per tab. To work on this, the experience working on the browser for the Nintendo 3DS system under a limited memory constraint helped us greatly.
Sasaki – Iwata Asks on Nintendo.com
In the box
The Wii U consists of a console unit which plugs into a TV (the first to support HD), and a wireless controller known as a gamepad. The gamepad is a lot bigger than typical TV console controllers, and it has a touchscreen on the front. The touchscreen is resistive, responding to pressure rather than electrical current. It’s intended to be used with a stylus (provided) but fingers can be used.
It might look a bit like one, but the gamepad isn’t a portable console designed to be taken out like the PS Vita. The gamepad can be used as a standalone screen with the TV switched off, as long as it’s within range of the console unit – it basically piggybacks off it.
It’s surprisingly lightweight for its size. It has a wealth of detectors including 9-axis control. Sensors wake the device from sleep when it’s picked up. There’s also a camera on the front, and a headphone port and speakers, with audio coming through both the TV and the gamepad giving a surround sound feel.
Up to six tabs can be opened at once, and the browser can be used while games are paused. There’s a really nice little feature here – the current game’s name is saved as a search option, so it’s really quick to look up contextual content such as walk-throughs.
Controls
Only one gamepad can be used to control the browser, but if there are Wiimotes connected, they can be used as pointers. This doesn’t let the user do anything except point (they each get a little hand icon with a number on it displayed on the screen), but it’s interesting that multiple people can be interacting with a site at once.
See a bigger version
The gamepad can also be used as a simple TV remote control, with basic functions such as bringing up the programme guide, adjusting volume and changing channel. I found the simplified interface much more usable than a full-featured remote control.
I’m used to scrolling being sluggish on consoles, but the Wii U feels almost as snappy as a desktop browser. Sites load considerably faster compared with others I’ve tested.
Tilt-scroll
Holding down ZL and ZR while tilting the screen activates an Instapaper-style tilt to scroll for going up and down the page quickly, useful for navigating very long pages.
Second screen
The TV mirrors most of what’s on the gamepad, although the TV screen just displays the contents of the browser window, while the gamepad displays the site along with the browser toolbar.
When the user with the gamepad is typing, the keyboard is hidden from the TV screen – there’s just a bit of text at the top indicating what’s happening on the gamepad.
Pressing X draws an on-screen curtain over the TV, hiding the content that’s on the gamepad from the TV. Pressing X again opens the curtains, revealing what’s on the gamepad. Holding the button down plays a drumroll before it’s released and the curtains are opened. I can imagine this being used in meetings as a fun presentation tool.
In a sense, browsing is a personal activity, but you get the idea that people will be coming and going through the room. When I first saw the curtain function, it made a huge impression on me. I walked around with it all over the company saying, “They’ve really come up with something amazing!”

Writing text
Unlike the capacitive screens on smartphones, the Wii U’s resistive screen needs to be pressed harder than you’re probably used to for registering a touch event. The gamepad screen is big, which makes it much easier to type on this device than other handheld consoles, even without the stylus. It’s still more fiddly than a full-sized keyboard though. When you’re designing forms, consider the extra difficulty console users experience.
Although TV screens are physically big, they are typically viewed from further away than desktop screens. This makes readability an issue, so Nintendo have provided not one, but four ways to zoom in and out:
Double-tapping on the screen.
Tapping the on-screen zoom icons in the browser toolbar.
Pressing the + and - buttons on the device.
Moving the right analogue stick up and down.
As well as making it easy to zoom in and out, Nintendo have done a few other things to improve the reading experience on the TV.
System font
One thing you’ll notice pretty quickly is that the browser lacks all the fonts we’re used to falling back to. Serif fonts are replaced with the system’s sans-serif font. I couldn’t get Typekit’s font loading method to work but Fontdeck, which works slightly differently, does display custom fonts.
The system font has been optimised for reading at a distance and is easy to distinguish because the lowercase e has a quirky little tilt.
Don’t lose :focus
Using the D-pad to navigate is similar to using a keyboard. Individual links are focused on, with a blue outline drawn around them.
The recently redesigned An Event Apart site is an example that improves the experience for keyboard and D-pad users. They’ve added a yellow background colour to links on focus. It feels nicer than the default blue outline on its own.
Media
This year, television overtook PCs as the primary way to watch online video content. TV is the natural environment for video, and 42% of online TVs in the US are connected to the internet via a console. Unfortunately, the <video> tag isn’t supported in most console browsers, and those that have Flash installed often have such an old version that the video won’t play.
I suspect this has been a big driver in getting console browsers to support web standards. The Wii U is designed with video content in mind. It doesn’t support Flash but it does support the HTML5 <video> tag.
Some video formats can’t be played, but those that are supported bring up an optimised interface with a custom scrub bar. This is where the device switches from mirroring the TV to being a second screen. The full-screen video is displayed on the TV, and the interface on the gamepad.
The really clever bit is that while a video is playing, the gamepad user can keep the video playing on the TV screen while searching for another video or browsing the web. This is the same for images too.
On the left, the video is being shown full-screen on the TV and gamepad. Only the gamepad gets the scrub bar. Clicking the slide up/down button (circled) lets the gamepad user browse the web while the video on the TV continues to play full-screen, as shown in the image on the right.
There’s support for SVG images, and they look great on a high-definition TV screen. However, there’s currently no way to save or download files.
Preparing for console users
I wasn’t expecting to be quite as impressed as I am by this browser. It’s encouraging to see console makers investing time into improving the experience as well as the standards support. In the same way there was an explosion in mobile browser use as the experience got better, I’m sure we’ll see the same with console browsers as the experience improves.
The value of detection
Consoles offer a range of inputs including gesture, voice and controller buttons. That means we have to think about more diverse methods of input than just touch and click.
This is where I could tell you to add some detection methods such as user agent string sniffing to target a different experience for console users. But the majority of the time, that really isn’t necessary. TV console browsers are getting a lot better at compensating for the living room environment, and they’re designed to work with websites that haven’t been optimised for this context.
Rather than tighten our grip on optimising experiences for every device out there, we’ve got to be pragmatic. There are so many new devices coming out every week, our designs need to be future-proof rather than fixed to a particular device in time.
Even fuzzy device detection isn’t reliable – the PS Vita declares itself to be mobile, a mobile device and a Kindle Fire tablet, while the two DS devices state they’re neither mobile nor mobile phones nor tablets, but computers. They’re weird outliers, but they’re still important devices to consider.
Thinking broadly about how our designs will be interacted with and viewed on a TV screen can help improve that experience for everyone. This is about accessibility. Considering how someone uses a site with a D-pad, we can improve the experience for keyboard users. When we think about colour contrast and text legibility on TV screens, we can apply that for anyone who reads content on the web. So why just offer this to the TV users?
Playing with the browser
…we want to prove to them through this Wii U Internet Browser that browsing itself can be an entertainment.
Iwata – Iwata Asks on Nintendo.com
Although I’m cautious about designing experiences for specific devices, it’s fun to experiment with the technology available. Nintendo have promised web developers access to the Wii U’s buttons and sensors. There’s already some JavaScript documentation, and a demo for you to try.
If you’re interested in making your own games, thanks to web standards, a lot of HTML5 games work already on the device. Matt Hackett wrote up his experience of testing the game he built, and he talks about some of features the browser lacks. There’s certainly an incentive there for console manufacturers to improve their HTML5 support so more games can be played in their browser.
What excites me about consoles is that it’s like looking at what might be available to us in future browsers. As well as thinking about how our sites work on small screens, we should also consider big screens. We’re already figuring out how images should work at different screen widths and connection speeds, but we’ve also got some interesting challenges ahead of us catering for second screen experiences and 3D-enabled devices.
So, this Christmas, if you’re huddled round the game console or a smart TV, give the browser in it a try. |

Designing for Perfection |
Hello, 24 ways readers. I hope you’re having a nice run up to Christmas. This holiday season I thought I’d share a few things with you that have been particularly meaningful in my work over the last year or so. They may not make you wet your santa pants with new-idea-excitement, but in the context of 24 ways I think they may serve as a nice lesson and a useful seasonal reminder going into the New Year. Enjoy!
Story
Despite being a largely scruffy individual for most of my life, I had some interesting experiences regarding kitchen tidiness during my third year at university.
As a kid, my room had always been pretty tidy, and as a teenager I used to enjoy reordering my CDs regularly (by artist, label, colour of spine – you get the picture); but by the time I was twenty I’d left most of these traits behind me, mainly due to a fear that I was turning into my mother. The one remaining anally retentive part of me that remained however, lived in the kitchen. For some reason, I couldn’t let all the pots and crockery be strewn across the surfaces after cooking. I didn’t care if they were washed up or not, I just needed them tidied. The surfaces needed to be continually free of grated cheese, breadcrumbs and ketchup spills. Also, the sink always needed to be clear. Always. Even a lone teabag, discarded casually into the sink hours previously, would give me what I used to refer to as “kitchen rage”.
Whilst this behaviour didn’t cause any direct conflicts, it did often create weirdness. We would be happily enjoying a few pre-night out beverages (Jack Daniels and Red Bull – nice) when I’d notice the state of the kitchen following our round of customized 49p Tesco pizzas. Kitchen rage would ensue, and I’d have to blitz the kitchen, which usually resulted in me having to catch everyone up at the bar afterwards.
One evening as we were just about to go out, I was stood there, in front of the shithole that was our kitchen with the intention of cleaning it all up, when a realization popped into my head. In hindsight, it was a pretty obvious one, but it went along the lines of “What the fuck are you doing? Sort your life out”. I sodded the washing up, rolled out with my friends, and had a badass evening of partying.
After this point, whenever I got the urge to clean the kitchen, I repeated that same realization in my head. My tidy kitchen obsession strived for a level of perfection that my housemates just didn’t share, so it was ultimately pointless. It didn’t make me feel that good, either; it was like having a cigarette after months of restraint – initially joyous but soon slightly shameful.
Lesson
Now, around seven years later, I’m a designer on the web and my life is chaotic. It features no planning for significant events, no day-to-day routine or structure, no thought about anything remotely long-term, and I like to think I do precisely what I want. It seems my days at striving for something ordered and tidy, in most parts of my life, are long gone.
For much of my time as a designer, though, it’s been a different story. I relished industry-standard terms such as ‘pixel perfection’ and ‘polished PSDs’, taking them into my stride as I strove to design everything that was put on my plate perfectly. Even down to grids and guidelines, all design elements would be painstakingly aligned to a five-pixel grid. There were no seven-pixel margins or gutters to be found in my design work, that’s for sure. I put too much pride and, inadvertently, too much ego into my work. Things took too long to create, and because of the amount of effort put into the work, significant changes, based on client feedback for example, were more difficult to stomach.
Over the last eighteen months I’ve made a conscious effort to change the way I approach designing for the web. Working on applications has probably helped with this; they seem to have a more organic development than rigid content-based websites. Mostly though, a realization similar to my kitchen rage one came about when I had to make significant changes to a painstakingly crafted Photoshop document I had created. The changes shouldn’t have been difficult or time-consuming to implement, but they were turning out to be. One day, frustrated with how long it was taking, the refrain “What the fuck are you doing? Sort your life out” again entered my head. I blazed the rest of the work, not rushing or doing scruffy work, but just not adhering to the insane levels of perfection I had previously set for myself. When the changes were presented, everything went down swimmingly. The client in this case (and I’d argue most cases) cared more about the ideas than the perfect way in which they had been implemented. I had taken myself and my ego out of the creative side of the work, and it had been easier to succeed.
Argument
I know many other designers who work on the web share such aspirations to perfection. I think it’s a common part of the designer DNA, but I’m not sure it really has a place when designing for the web.
First, there’s the environment. The landscape in which we work is continually shifting and evolving. The inherent imperfection of the medium itself makes attempts to create perfect work for it redundant. Whether you consider it a positive or negative point, the products we make are never complete. They’re always scaling and changing.
Like many aspects of web design, this striving for perfection in our design work is a way of thinking borrowed from other design industries where it’s more suited. A physical product cannot be as easily altered or developed after it has been manufactured, so the need to achieve perfection when designing is more apt.
Designers who can relate to anything I’ve talked about can easily let go of that anal retentiveness if given the right reasons to do so. Striving for perfection isn’t a bad thing, but I simply don’t think it can be achieved in such a fast-moving, unique industry. I think design for the web works better when it begins with quick and simple, followed by iteration and polish over time.
To let go of ego and to publish something that you’re not completely happy with is perhaps the most difficult part of the job for designers like us, but it’s followed by a satisfaction of knowing your product is alive and breathing, whereas others (possibly even competitors) may still be sitting in Photoshop, agonizing over whether a margin should be twenty or forty pixels.
I keep telling myself to stop sitting on those two hundred ideas that are all half-finished. Publish them, clean them up and iterate over time. I’ve been telling myself this for months and, hopefully, writing this article will give me the kick in the arse I need. Hopefully, it will also give someone else the same kick. |

Collaborative Development for a Responsively Designed Web |
In responsive web design we’ve found a technique that allows us to design for the web as a medium in its own right: one that presents a fluid, adaptable and ever changing canvas.
Until this point, we gave little thought to the environment in which users will experience our work, caring more about the aggregate than the individual. The applications we use encourage rigid layouts, whilst linear processes focus on clients signing off paintings of websites that have little regard for behaviour and interactions. The handover of pristine, pixel-perfect creations to developers isn’t dissimilar to farting before exiting a crowded lift, leaving front-end developers scratching their heads as they fill in the inevitable gaps. If you haven’t already, I recommend reading Drew’s checklist of things to consider before handing over a design.
Somehow, this broken methodology has survived for the last fifteen years or so. Even the advent of web standards has had little impact. Now, as we face an onslaught of different devices, the true universality of the web can no longer be ignored.
Responsive web design is just the thin end of the wedge. Largely concerned with layout, its underlying philosophy could ignite a trend towards interfaces that adapt to any number of different variables: input methods, bandwidth availability, user preference – you name it!
With such adaptability, a collaborative and iterative process is required. Ethan Marcotte, who worked with the team behind the responsive redesign of the Boston Globe website, talked about such an approach in his book:
The responsive projects I’ve worked on have had a lot of success combining design and development into one hybrid phase, bringing the two teams into one highly collaborative group.
Whilst their process still involved the creation of desktop-centric mock-ups, these were presented to the entire team early on, where questions about how pages might adapt and behave at different sizes were asked. Mock-ups were quickly converted into HTML prototypes, meaning further decisions could be based on usage rather than guesswork (and endless hours spent in Photoshop).
Regardless of the exact process, it’s clear that the relationship between our two disciplines is more crucial than ever. Yet, historically, it seems a wedge has been driven between us – perhaps a result of segregation and waterfall-style processes – resulting in animosity.
So how can we improve this relationship? Ultimately, we’ll need to adapt, but even within existing workflows we can start to overlap. Simply adjusting our attitude can effect change, and bring design and development teams closer together.
Good design is constant contact.
Mark Otto
The way we work needs to be more open and inclusive. For example, ensuring members of the development team attend initial kick-off meetings and design workshops will not only ensure technical concerns are raised, but mean that those implementing our designs better understand the problems we’re trying to solve.
It can also be useful at this stage to explain how you work and the sort of deliverables you expect to produce. This will give developers a chance to make recommendations on how these can be optimized for their own needs.
You may even find opportunities to share the load. On a recent project I worked on, our development partners offered to produce the interactive prototypes needed for user testing. This allowed us to concentrate on refining the experience, whilst they were able to get a head start on building the product.
While developers should be involved at the beginning of projects, it’s also important that designers are able to review and contribute to a product as it’s being built. Any handover should be done in person, and ideally you’ll have a day set aside to do so. Having additional budget available for follow-up design reviews is also recommended. Learning how to use version control tools like Subversion or Git will allow you to work within the same environment as developers, and allow you to contribute code or graphic assets directly to a project if needed.
Don’t underestimate the benefits of designer and developer sitting next to each other. Subtle nuances can be explored far more easily than if they were conducted over email or phone. As Ethan writes, “‘Design’ is the means, not merely the end; the path we walk over the course of a project, the choices we make”.
It’s from collaboration like this that I’ve become fond of producing visual style guides. These demonstrate typographic treatments for common markup and patterns (blockquotes, lists, pagination, basic form controls and so on). Thinking in terms of components rather than individual pages not only fits in better with how a developer will implement a site, but can also ensure your design works as a coherent whole.
Despite the amount of research and design produced, when it comes to the crunch, there will always be a need for compromise. As the old saying goes, ‘fast, cheap and good – pick two.’ It’s important that you know which pieces are crucial to a design and which areas can allow for movement. Pick your battles wisely. Having an agreed set of design principles can be useful when making such decisions, as they help everyone focus on the goals of the project.
The best compromises are reached when both sides understand the issues of the other.
Richard Rutter
Ultimately, better collaboration comes through a shared understanding of the different competencies required to build a website. Instead of viewing ourselves in terms of discrete roles, we should instead look to emphasize our range of abilities, and work with others whose skills are complementary.
Perhaps somebody who actively seeks to broaden their knowledge is the mark of a professional. Seek these people out.
The best developers I’ve worked with have a respect for design, probably having attempted to do some themselves! Having wrangled with a few MySQL databases myself, I certainly believe the obverse is true. While knowing HTML won’t necessarily make you a better designer, it will help you understand the issues being faced by a front-end developer and, more importantly, allow you to offer solutions or alternative approaches.
So take a moment to think about how you work with developers and how you could improve your relationship with them. What are you doing to ease the path towards our collaborative future? |

Taming Complexity |
I’m going to step into my UX trousers for this one. I wouldn’t usually wear them in public, but it’s Christmas, so there’s nothing wrong with looking silly.
Anyway, to business. Wherever I roam, I hear the familiar call for simplicity and the denouncement of complexity. I read often that the simpler something is, the more usable it will be. We understand that simple is hard to achieve, but we push for it nonetheless, convinced it will make what we build easier to use. Simple is better, right?
Well, I’ll try to explore that. Much of what follows will not be revelatory to some but, like all good lessons, I think this serves as a welcome reminder that as we live in a complex world it’s OK to sometimes reflect that complexity in the products we build.
Myths and legends
Less is more, we’ve been told, ever since master of poetic verse Robert Browning used the phrase in 1855. Well, I’ve conducted some research, and it appears he knew nothing of web design. Neither did modernist architect Ludwig Mies van der Rohe, a later pedlar of this worthy yet contradictory notion. Broad is narrow. Tall is short. Eggs are chips. See: anyone can come up with this stuff.
To paraphrase Einstein, simple doesn’t have to be simpler. In other words, simple doesn’t dictate that we remove the complexity. Complex doesn’t have to be confusing; it can be beautiful and elegant. On the web, complex can be necessary and powerful. A website that simplifies the lives of its users by offering them everything they need in one site or screen is powerful. For some, the greater the density of information, the more useful the site.
In our decision-making process, principles such as Occam’s razor’s_razor (in a nutshell: simple is better than complex) are useful, but simple is for the user to determine through their initial impression and subsequent engagement. What appears simple to me or you might appear very complex to someone else, based on their own mental model or needs. We can aim to deliver simple, but they’ll be the judge.
As a designer, developer, content alchemist, user experience discombobulator, or whatever you call yourself, you’re often wrestling with a wealth of material, a huge number of features, and numerous objectives. In many cases, much of that stuff is extraneous, and goes in the dustbin. However, it can be just as likely that there’s a truckload of suggested features and content because it all needs to be there. Don’t be afraid of that weight.
In the right hands, less can indeed mean more, but it’s just as likely that less can very often lead to, well… less.
Complexity is powerful
Simple is the ability to offer a powerful experience without overwhelming the audience or inducing information anxiety. Giving them everything they need, without having them ferret off all over a site to get things done, is important.
It’s useful to ask throughout a site’s lifespan, “does the user have everything they need?” It’s so easy to let our designer egos get in the way and chop stuff out, reduce down to only the things we want to see. That benefits us in the short term, but compromises the audience long-term.
The trick is not to be afraid of complexity in itself, but to avoid creating the perception of complexity. Give a user a flight simulator and they’ll crash the plane or jump out. Give them everything they need and more, but make it feel simple, and you’re building a relationship, empowering people.
This can be achieved carefully with what some call gradual engagement, and often the sensible thing might be to unleash complexity in carefully orchestrated phases, initially setting manageable levels of engagement and interaction, gradually increasing the inherent power of the product and fostering an empowered community.
The design aesthetic
Here’s a familiar scenario: the client or project lead gets overexcited and skips most of the important decision-making, instead barrelling straight into a bout of creative direction Tourette’s. Visually, the design needs to be minimal, white, crisp, full of white space, have big buttons, and quite likely be “clean”. Of course, we all like our websites to be clean as that’s more hygienic.
But what do these words even mean, really? Early in a project they’re abstract distractions, unnecessary constraints. This premature narrowing forces us to think much more about throwing stuff out rather than acknowledging that what we’re building is complex, and many of the components perhaps necessary.
Simple is not a formula. It cannot be achieved just by using a white background, by throwing things away, or by breathing a bellowsful of air in between every element and having it all float around in space. Simple is not a design treatment. Simple is hard. Simple requires deep investigation, a thorough understanding of every aspect of a project, in line with the needs and expectations of the audience.
Recognizing this helps us empathize a little more with those most vocal of UX practitioners. They usually appreciate that our successes depend on a thorough understanding of the user’s mental models and expected outcomes. I personally still consider UX people to be web designers like the rest of us (mainly to wind them up), but they’re web designers that design every decision, and by putting the user experience at the heart of their process, they have a greater chance of finding simplicity in complexity. The visual design aesthetic — the façade — is only a part of that.
Divide and conquer
I’m currently working on an app that’s complex in architecture, and complex in ambition. We’ll be releasing in carefully orchestrated private phases, gradually introducing more complexity in line with the unavoidably complex nature of the objective, but my job is to design the whole, the complete system as it will be when it’s out of beta and beyond.
I’ve noticed that I’m not throwing much out; most of it needs to be there. Therefore, my responsibility is to consider interesting and appropriate methods of navigation and bring everything together logically.
I’m using things like smart defaults, graphical timelines and colour keys to make sense of the complexity, techniques that are sympathetic to the content. They act as familiar points of navigation and reference, yet are malleable enough to change subtly to remain relevant to the information they connect. It’s really OK to have a lot of stuff, so long as we make each component work smartly.
It’s a divide and conquer approach. By finding simplicity and logic in each content bucket, I’ve made more sense of the whole, allowing me to create key layouts where most of the simplified buckets are collated and sometimes combined, providing everything the user needs and expects in the appropriate places.
I’m also making sure I don’t reduce the app’s power. I need to reflect the scale of opportunity, and provide access to or knowledge of the more advanced tools and features for everyone: a window into what they can do and how they can help. I know it’s the minority who will be actively building the content, but the power is in providing those opportunities for all.
Much of this will be familiar to the responsible practitioners who build websites for government, local authorities, utility companies, newspapers, magazines, banking, and we-sell-everything-ever-made online shops. Across the web, there are sites and tools that thrive on complexity.
Alas, the majority of such sites have done little to make navigation intuitive, or empower audiences. Where we can make a difference is by striving to make our UIs feel simple, look wonderful, not intimidating — even if they’re mind-meltingly complex behind that façade.
Embrace, empathize and tame
So, there are loads of ways to exploit complexity, and make it seem simple. I’ve hinted at some methods above, and we’ve already looked at gradual engagement as a way to make sense of complexity, so that’s a big thumbs-up for a release cycle that increases audience power.
Prior to each and every release, it’s also useful to rest on the finished thing for a while and use it yourself, even if you’re itching to release. ‘Ready’ often isn’t, and ‘finished’ never is, and the more time you spend browsing around the sites you build, the more you learn what to question, where to add, or subtract. It’s definitely worth building in some contingency time for sitting on your work, so to speak.
One thing I always do is squint at my layouts. By squinting, I get a sort of abstract idea of the overall composition, and general feel for the thing. It makes my face look stupid, but helps me see how various buckets fit together, and how simple or complex the site feels overall.
I mentioned the need to put our design egos to one side and not throw out anything useful, and I think that’s vital. I’m a big believer in economy, reduction, and removing the extraneous, but I’m usually referring to decoration, bells and whistles, and fluff. I wouldn’t ever advocate the complete removal of powerful content from a project roadmap.
Above all, don’t fear complexity. Embrace and tame it. Work hard to empathize with audience needs, and you can create elegant, playful, risky, surprising, emotive, delightful, and ultimately simple things. |

Getting the Most Out of Google Analytics |
Something a bit different for today’s 24 ways article. For starters, I’m not a designer or a developer. I’m an evil man who sells things to people on the internet. Second, this article will likely be a little more nebulous than you’re used to, since it covers quite a number of points in a relatively short space.
This isn’t going to be the complete Google Analytics Conversion University IQ course compressed into a single article, obviously. What it will be, however, is a primer on setting up and using Google Analytics in real life, and a great deal of what I’ve learned using Google Analytics nearly every working day for the past six (crikey!) years.
Also, to be clear, I’ll be referencing new Google Analytics here; old Google Analytics is for loooosers (and those who want reliable e-commerce conversion data per site search term, natch).
You may have been running your Analytics account for several years now, dipping in and out, checking traffic levels, seeing what’s popular… and that’s about it. Google Analytics provides so much more than that, but the number of reports available can often intimidate users, and documentation and case studies on their use are minimal at best.
Let’s start! Setting up your Analytics profile
Before we plough on, I just want to run through a quick checklist that some basic settings have been enabled for your profile. If you haven’t clicked it, click the big cog on the top-right of Google Analytics and we’ll have a poke about.
If you have an e-commerce site, e-commerce tracking has been enabled
If your site has a search function, site search tracking has been enabled.
Query string parameters that you do not want tracked as separate pages have been excluded (for example, any parameters needed for your platform to function, otherwise you’ll get multiple entries for the same page appearing in your reports)
Filters have been enabled on your main profile to exclude your office IP address and any IPs of people who frequently access the site for work purposes. In decent numbers they tend to throw data off a tad.
You may also find the need to set up multiple profiles prefiltered for specific audience segments. For example, at Lovehoney we have seventeen separate profiles that allow me quick access to certain countries, devices and traffic sources without having to segment first. You’ll also find load time for any complex reports much improved. Use the same filter screen as above to set up a series of profiles that only include, say, mobile visits, or UK visitors, so you can quickly analyse important segments.
Matt, what’s a segment?
A segment is a subsection of your visitor base, which you define and then call on in reports to see specific data for that subsection. For example, in this report I’ve defined two segments, the first for IE6 users and the second for IE7.
Segments are easily created by clicking the Advanced Segments tabs at the top of any report and clicking +New Custom Segment.
What does your site do?
Understanding the goals of your site is an oft-covered topic, but it’s necessary not just to form a better understand of your business and prioritize your time. Understanding what you wish visitors to do on your site translates well into a goal-driven analytics package like Google Analytics.
Every site exists essentially to sell something, either financially through e-commerce, or to sell an idea or impart information, get people to download a CV or enquire about service, or to sell space on that website to advertisers. If the site did not provide a positive benefit to its owners, it would not have a reason for being.
Once you have understood the reason why you have a site, you can map that reason on to one of the three goal types Google Analytics provides.
E-commerce
This conversion type registers transactions as part of a sales process which requires a monetary value, what products have been bought, an SKU (stock keeping unit), affiliation (if you’re then attributing the sale to a third party or franchise) and so on.
The benefit of e-commerce tracking is not only assigning non-arbitrary monetary value to behaviour of visitors on your site, as well as being able to see ancillary costs such as shipping, but seeing product-level information, like which products are preferred from various channels, popular categories, and so on.
However, I find the e-commerce tracking options also useful for non-e-commerce sites. For example, if you’re offering downloads or subscriptions and having an email address or user’s details is worth something to you, you can set up e-commerce tracking to understand how much value your site is bringing. For example, an email address might be worth 20p to you, but if it also includes a name it’s worth 50p. A contact telephone number is worth £2, and so on.
Page goals
Page goals, unsurprisingly, track a visit to a page (often with a sequence of pages leading up to that page). This is what’s referred to as a goal funnel, and is generally used to track how visitors behave in a multistep checkout.
Interestingly, the page doesn’t have to actually exist. For example, if you have a single page checkout, you can register virtual page views using trackPageview() when a visitor clicks into a particular section of the checkout or other form. If your site is geared towards getting someone to a particular page, but where there isn’t a transaction (for example, a subscription page) this is for you.
There are also behavioural goals, such as time on site and number of pages viewed, which are geared towards sites that make money from advertising.
But, going back to the page goals, these can be abstracted using regular expressions, meaning that you can define a funnel based on page type rather than having to set individual folders.
In this example, I’ve created regexes for the main page types on my site, so I can create a wide funnel that captures visitors from where they enter through to checkout.
Events
Event tracking registers a predefined event, such as playing a video, or some interaction that can trigger JavaScript, such as a Tweet This button. Events can then be triggered using the trackEvent() call. If you want someone to complete watching a video, you would code your player to fire trackEvent() upon completion.
While I don’t use events as goals, I use events elsewhere to see how well a video play aids to conversion. This not only helps me justify the additional spend on creating video content, but also quickly highlights which videos are underperforming as sales tools.
What a visitor can tell you
Now you have some proper goals set up, we can start to see how changes in content (on-site and external) affect those goals.
Ultimately, when a visitor comes to your site, they bring information with them:
where they came from (a search engine – including: keyword searched for; a referral; direct; affiliate; or ad campaign)
demographics (country; whether they’re new or returning, within thirty days)
technical information (browser; screen size; device; bandwidth)
site-specific information (landing page; next click; previous values assigned to them as custom variables*)
* A note about custom variables. There’s no hope in hell that I can cover custom variables in this article. Go research them. Custom variables are the single best way to hack Google Analytics and bend it to your will. Custom variables allow you to record anything you want about a visitor, which that visitor will then carry around with them between visits. It’s also great for plugging other services into Google Analytics (as shown by the marvelous way Visual Website Optimizer allows you to track and segment tests within the GA interface). Just make sure not to breach the terms of service, eh?
CSI your website
Police procedural TV shows are all the same: the investigators are called to a crime and come across a clue; there’s then an autopsy; new evidence leads them to a new location; they find a new clue; they put two and two together; they solve the mystery.
This is your life now. Exciting!
So, now you’re gathering a wealth of information about what sort of people visit your site, what they do when they’re there, and what eventually gets them to drive value to you. It’s now your job to investigate all these little clues to see which types of people drive the most value, and what you can change to improve it.
Maybe not that exciting.
However, Google Analytics comes pre-armed with extensive reports for you to delve into. As an e-commerce guy (as opposed to a page goal guy) my day pretty much follows the pattern below.
Look at e-commerce conversion rate by traffic source compared to the same day in the previous week and previous month. As ours is an e-commerce site, we have weekly and monthly trends. A big spike on Sundays and Mondays, and payday towards the end of the month is always good; on the third week of a month there tends to be a lull. Spend time letting your Google Analytics data brew, understand your own trends and patterns, and you’ll start to get a feel for when something isn’t quite right.
Traffic Sources → Sources → All Traffic
Look at the conversion rate by landing page for any traffic source that feels significantly different to what’s expected. Check bounce rates, drill down to likely landing pages and check search keyword or referral site to see if it’s a particular subset of visitor. You can do this by clicking Secondary Dimension and choosing Keyword or Source. If it’s direct, choose Visitor Type to break down by new or returning visitor.
Content → Site Content → Landing Pages
I then tend to flip into Content Drilldown to see what the next clicks were from those landing pages, and whether they changed significantly to the date I’m comparing with. If they have, that’s usually an indicator of changed content (or its relevancy). Remember, if a bunch of people have found their way to your page via a method you’re not expecting (such as a mention on a Spanish radio station – this actually happened to me once), while the content hasn’t changed, the relevancy of it to the audience may have.
Content → Site Content → Content Drilldown
Once I have an idea of what content was consumed, and whether it was relevant to the user, I then look at the visitor specifics, such as browser or demographic data, to see again whether the change was limited to a specific subset. Site speed, for example, is normally a good factor towards bounce rate, so compare that with previous data as well.
Now, to be investigating at this level you still need a serious amount of data, in order to tell what’s a significant change or not. If you’re struggling with a small number of visitors, you might find reporting on a weekly or fortnightly basis more appropriate.
However, once you’ve looked into the basics of why changes happen to the value of your site, you’ll soon find yourself limited by the reports offered in Standard Reporting. So, it’s time to build your own. Hooray!
Custom reporting
Google Analytics provides the tools to build reports specific to the types of investigations you frequently perform.
Welcome to my world.
Custom reports are quite simple to build: first, you determine the metric you want the report to cover (number of visitors, bounce rate, conversion rate, and so on), then choose a set of dimensions that you’d like to segment the report by (say, the source of the traffic, and whether they were new or returning users). You can filter the report, including or excluding particular dimension values, and you can assign the report to any of the profiles you created earlier.
In the example below, I’ve created a report that shows me visits and conversion rate for any Google traffic that landed directly only on a product page. I can then drill down on each product page to see the complete phrases use to search. I can use this information in two ways:
I can see which products aren’t converting, which shows me where I need to work harder on merchandising.
I can give this information to my content team, showing them the actual phrases visitors used to reach our product content, helping them write better targeted product descriptions.
The possibilities here are nearly endless, but here are a few examples of reports I find useful:
Non-brand inbound search
By creating a report that shows inbound search traffic which doesn’t include your brand, you can see more clearly the behaviour of visitors most likely to be unfamiliar with your site and brand values, without having to rely on the clumsy new or returning demographic date.
Traffic/conversion/sales by hour
This is pure stats porn, but actually more useful than real-time data. By seeing this data broken down at an hourly level, you can not only compare the current day to previous days, but also see the best performing times for email broadcasts and tweets.
Visits, load time, conversion and sales by page and browser
Page speed can often kill conversion rates, but it’s difficult to prove the value of focusing on speed in monetary terms. Having this report to hand helps me drive Operation Greenbelt, our effort to get into the sub-1.5 second band in Google Webmaster Tools.
Useful things you can’t do in custom reporting
If you have a search function on your website, then Conversion Rate and Products Bought by Site Search Term is an incredibly useful report that allows you to measure the effectiveness of your site’s search engine at returning products and content related to the search term used. By including the products actually bought by visitors who searched for each term, you can use this information to better searchandise these results, escalating high propensity and high value products to the top of the results.
However, it’s not possible to get this information out of new Google Analytics.
Try it, select the following in the report builder:
Metrics: total unique searches; e-commerce or goal conversion rate
Dimensions: search term; product
You’ll see that the data returned is a little nonsensical, though a 2,000% conversion rate would be nice. However, you can get more accurate information using advanced segments. By creating individual segments to define users who have searched for a particular term, you can run the sales performance and product performance reports as normal. It’s laborious, but it teaches a good lesson: data that seems inaccessible can normally be found another way!
Reporting infrastructure
Now that you have a series of reports that you can refer to on a daily or weekly basis, it’s time to put together a regular reporting infrastructure.
Even if you’re not reporting to someone, having a set of key performance indicators that you can use to see how your performance is improving over time allows you to set yourself business goals on a monthly and annual basis.
For my own reporting, I take some high-level metrics (such as visitors, conversion rate and average order value), and segment them by traffic source and, separately, landing page. These statistics I record weekly and report:
current week compared with previous week
same week previous year (if available)
4 week average
13 week average
52 week average (if available)
This takes into account weekly, monthly, seasonal and annual trends, and gives you a much clearer view of your performance.
Getting data in other ways
If you’re using Google Analytics frequently, with any large site you’ll come to a couple of conclusions:
Doing any kind of practical comparative analysis is unwieldy.
Boy, Google Analytics is slow!
As you work with bigger datasets and put together more complex queries, you’ll see the loading graphic more than you’ll see actual data. So when you reach that level, there are ways to completely bypass the Google Analytics interface altogether, and get data into your own spreadsheet application for manipulation.
Data Feed Query Explorer
If you just want to pull down some quick statistics but still use complex filters and exotic metric and dimension combinations, the Data Feed Query Explorer is the quickest way of doing so. Authenticate with your Google Analytics account, select a profile, and you can start selecting metrics and dimensions to be generated in a handy, selectable tabulated format.
Google Analytics API
If you’re feeling clever, you can bypass having to copy and paste data by pulling in directly into Excel, Google Docs or your own application using the Google Analytics API. There are several scripts and plugins available to do this. I use Automate Analytics Google Docs code (there’s also a paid version that simplifies setup and creates some handy reports for you).
New shiny things
Well, now that that’s over, I can show you some cool stuff. Well, at least it’s cool to me. Google Analytics is being constantly improved and new functionality is introduced nearly every month. Here are a couple of my favourites.
Multichannel attribution
Not every visitor converts on your site on the first visit. They may not even do so on the second visit, or third. If they convert on the fourth visit, but each time they visit they do so via a different channel (for example, Search PPC, Search Organic, Direct, Email), which channel do you attribute the conversion to? The last channel, or the first? Dilemma!
Google now has a Multichannel Attribution report, available in the Conversion category, which shows how each channel assists in converting, the overlap between channels, and where in the process that channel was important.
For example, you may have analysed your blog traffic from Twitter and become disheartened that not many people were subscribing after visiting from Twitter links, but instead your high-value subscribers were coming from natural search. On the face of it, you’d spend less time tweeting, but a multichannel report may tell you that visitors first arrived via a Twitter link and didn’t subscribe, but then came back later after searching for your blog name on Google, after which they did. Don’t pack Twitter in yet!
Visitor and goal flow
Visitor and goal flow are amazing reports that help you visualize the flow of traffic through your site and, ultimately, into your checkout funnel or similar goal path. Flow reports are perfect for understanding drop-off points in your process, as well as what the big draws are on each page.
Previously, if you wanted to visualize this data you had to set up several abstracted microgoals and chain them together in custom reports. Frankly, it was a pain in the arse and burned through your precious and limited goal allocation.
Visitor flow bypasses all that and produces the report in an interactive flow diagram. While it doesn’t show you the holy grail of conversion likelihood by each path, you can segment visitor flow so that you can see very specifically how different segments of your visitor base behave.

Adaptive Images for Responsive Designs… Again |
When I was asked to write an article for 24 ways I jumped at the chance, as I’d been wanting to write about some fun hacks for responsive images and related parsing behaviours. My heart sank a little when Matt Wilcox beat me to the subject, but it floated back up when I realized I disagreed with his method and still had something to write about.
So, Matt Wilcox, if that is your real name (and I’m pretty sure it is), I disagree. I see your dirty server-based hack and raise you an even dirtier client-side hack. Evil laugh, etc., etc.
You guys can stomach yet another article about responsive design, right? Right?
Half the room gets up to leave
Whoa, whoa… OK, I’ll cut to the chase…
TL;DR
In a previous episode, we were introduced to Debbie and her responsive cat poetry page. Well, now she’s added some reviews of cat videos and some images of cats. Check out her new page and have a play around with the browser window. At smaller widths, the images change and the design responds. The benefits of this method are:
it’s entirely client-side
images are still shown to users without JavaScript
your media queries stay in your CSS file
no repetition of image URLs
no extra downloads per image
it’s fast enough to work on resize
it’s pure filth
What’s wrong with the server-side solution?
Responsive design is a client-side issue; involving the server creates a boatload of problems.
It sets a cookie at the top of the page which is read in subsequent requests. However, the cookie is not guaranteed to be set in time for requests on the same page, so the server may see an old value or no value at all.
Serving images via server scripts is much slower than plain old static hosting.
The URL can only cache with vary: cookie, so the cache breaks when the cookie changes, even if the change is unrelated. Also, far-future caching is out for devices that can change width.
It depends on detecting screen width, which is rather messy on mobile devices.
Responding to things other than screen width (such as DPI) means packing more information into the cookie, and a more complicated script at the top of each page.
So, why isn’t this straightforward on the client?
Client-side solutions to the problem involve JavaScript testing user agent properties (such as screen width), looping through some images and setting their URLs accordingly. However, by the time JavaScript has sprung into action, the original image source has already started downloading. If you change the source of an image via JavaScript, you’re setting off yet another request.
Images are downloaded as soon as their DOM node is created. They don’t need to be visible, they don’t need to be in the document.
new Image().src = url
The above will start an HTTP request for url. This is a handy trick for quick requests and preloading, but also shows the browser’s eagerness to download images.
Here’s an example of that in action. Check out the network tab in Web Inspector (other non-WebKit development aids are available) to see the image requests.
Because of this, some client-side solutions look like this:
<img src="t.gif" data-src="real-image.jpg" data-bigger-src="real-bigger-image.jpg">
where t.gif is a 1×1px tiny transparent GIF.
This results in no images if JavaScript isn’t available. Dealing with the absence of JavaScript is still important, even on mobile. I was recently asked to make a website work on an old Blackberry 9000. I was able to get most of the way there by preventing that OS parsing any JavaScript, and that was only possible because the site didn’t depend on it.
We need to delay loading images for JavaScript users, but ensure they load for users without JavaScript. How can we conditionally parse markup depending on JavaScript support?
Oh yeah! <noscript>!
<noscript>
<img src="image.jpg">
</noscript>
Whoa! First spacer GIFs and now <noscript>? This really is the future! The image above will only load for users without JavaScript support. Now all we need to do is send JavaScript in there to get the textContent of the <noscript> element, then we can alter the image source before handing it to the DOM for parsing.
Here’s an example of that working … unless you’re using Internet Explorer.
Internet Explorer doesn’t retain the content of <noscript> elements. As soon as it’s parsed, it considers it an empty element. FANKS INTERNET EXPLORER. This is why some solutions do this:
<noscript data-src="image.jpg">
<img src="image.jpg">
</noscript>
so JavaScript can still get at the URL via the data-src attribute. However, repeating stuff isn’t great. Surely we can do better than that.
A dirty, dirty hack
Thankfully, I managed to come up with a solution, and by me, I mean someone cleverer than me. Pornel’s solution uses <noscript>, but surely we don’t need that.
Now, before we look at this, I can’t stress how dirty it is. It’s so dirty that if you’ve seen it, schools will refuse to employ you.
<script>document.write('<' + '!--')</script>
<img src="image.jpg">
<!---->
Phwoar! Dirty, isn’t it? I’ll stop for a moment, so you can go have a wash.
Done? Excellent.
With this, the image is wrapped in a comment only for users with JavaScript. Without JavaScript, we get the image. Unlike the <noscript> example above, we can get the text content of the comment pretty easily.
Hurrah! But wait… Some browsers are sometimes downloading the image, even with JavaScript enabled. Notably Firefox. Huh?
Images are downloaded in comments now? What?
No. What we’re seeing here is the effect of speculative parsing. Here’s what’s happening:
While the browser is parsing the script, it parses the rest of the document. This is usually a good thing, as it can download subsequent images and scripts without waiting for the script to complete. The problem here is we create an unbalanced tree.
An unbalanced tree, yesterday.
In this case, the browser must throw away its speculative parsing and reparse from the end of the <script> element, taking our document.write into consideration. Unfortunately, by this stage it may have already discovered the image and sent an HTTP request for it.
A dirty, dirty hack… that works
Pornel was right: we still need the <noscript> element to cater for browsers with speculative parsing.
<script>document.write('<' + '!--')</script><noscript>
<img src="image.jpg">
</noscript -->
And there we have it. We can now prevent images loading for users with JavaScript, but we can still get at the markup.
We’re still creating an unbalanced tree and there’s a performance impact in that. However, the parser won’t have got far by the time our script executes, so the impact is small. Unbalanced trees are more of a concern for external scripts; a lot of parsing can happen by the time the script has downloaded and parsed.
Using dirtiness to create responsive images
Now all we need to do is give each of our dirty scripts a class name, then JavaScript can pick them up, grab the markup from the comment and decide what to do with the images.
This technique isn’t exclusively useful for responsive images. It could also be used to delay images loading until they’ve scrolled into view. But to do that you’ll need a bulletproof way of detecting when elements are in view. This involves getting the height of the viewport, which is extremely unreliable on mobile devices.
Here’s a hastily thrown together example showing how it can be used for responsive images.
I adjust the end of the image URLs conditionally depending on the result of media queries. This is done on page load, and on resize.
I’m using regular expressions to alter the URLs. Using regex to deal with HTML is usually a sign of insanity, but parsing it with the browser’s DOM parser would trigger the download of images before we change the URLs. My implementation currently requires double-quoted image URLs, because I’m lazy. Wanna fight about it?
Media querying via JavaScript
Jeremy Keith used document.documentElement.clientWidth in his example, which is great as a proof of concept, but unfortunately is rather unreliable across mobile devices.
Thankfully, standards are coming to the rescue with window.matchMedia, which lets us provide a media query string and get a boolean result. There’s even a great polyfill for browsers that don’t support it (as long as they support media queries in CSS).
I didn’t go with that for three reasons:
I’d like to keep media queries in the CSS file, if possible.
I wanted something a little lighter to keep things speedy while resizing.
It’s just not dirty enough yet.
To make things ultra-dirty, I add a test element to the page with a specific class, let’s say media-test. Then, I control the width of it using media queries in my CSS file:
@media all and (min-width: 640px) {
.media-test {
width: 1px;
}
}
@media all and (min-width: 926px) {
.media-test {
width: 2px;
}
}
The JavaScript part changes the URL suffix depending on the width of media-test. I’m using a min-width media query, but you can use others such as pixel-ratio to detect high DPI displays. Basically, it’s a hacky way for CSS to set a value that can be picked up by JavaScript. It means the bit that signals changes to the images sits with the rest of the responsive code, without duplication.
Also, phwoar, dirty!
The API
I threw a script together to demonstrate the technique. I’m not particularly attached to it, I’m not even sure I like it, but here’s the API:
responsiveGallery({
// Class name of dirty script element(s) to target
scriptClass: 'dirty-gallery-script',
// Class name for our test element
testClass: 'dirty-gallery-test',
// The initial suffix of URLs, the bit that changes.
initialSuffix: '-mobile.jpg',
// A map of suffixes, for each width of 'dirty-gallery-test'
suffixes: {
'1': '-desktop.jpg',
'2': '-large-desktop.jpg',
'3': '-mobile-retina.jpg'
}
});
The API can cover individual images or multiple galleries at once. In the example I gave at the start of the article I make two calls to the API, one for both galleries, and one for the single image above the video reviews. They’re separate calls because they respond slightly differently.
The future
Hopefully, we’ll get a proper solution to this soon. My favourite suggestion is the <picture> element that Bruce Lawson covers.
<picture alt="Angry pirate">
<source src="hires.png" media="min-width:800px">
<source src="midres.png" media="min-width:480px">
<source src="lores.png">
<!-- fallback for browsers without support -->
<img src="midres.png" alt="Angry pirate">
</picture>
Unfortunately, we’re nowhere near that yet, and I’d still rather have my media queries stay in CSS. Perhaps the source elements could be skipped if they’re display:none; then they could have class names and be controlled via CSS. Sigh.
Well, I’m tired of writing now and I’m sure you’re tired of reading. I realize what I’ve presented is a yet another dirty hack to the responsive image problem (perhaps the dirtiest?) and may be completely unfeasible in professional situations. But isn’t that the true spirit of Christmas?
No. |

From Side Project to Not So Side Project |
In the last article I wrote for 24 ways, back in 2009, I enthused about the benefits of having a pet project, suggesting that we should all have at least one so that we could collaborate with our friends, escape our day jobs, fulfil our own needs, help others out, raise our profiles, make money, and — most importantly — have fun. I don’t think I need to offer any further persuasions: it seems that designers and developers are launching their own pet projects left, right and centre. This makes me very happy.
However, there still seems to be something of a disconnect between having a side project and turning it into something that is moderately successful; in particular, the challenge of making enough money to sustain the project and perhaps even elevating it from the sidelines so that it becomes something not so on the side at all.
Before we even begin this, let’s spend a moment talking about money, also known as…
Evil, nasty, filthy money
Over the last couple of years, I’ve started referring to myself as an accidental businessman. I say accidental because my view of the typical businessman is someone who is driven by money, and I usually can’t stand such people. Those who are motivated by profit, obsessed with growth, and take an active interest in the world’s financial systems don’t tend to be folks with whom I share a beer, unless it’s to pour it over them. Especially if they’re wearing pinstriped suits.
That said, we all want to make money, don’t we? And most of us want to make a relatively decent amount, too. I don’t think there’s any harm in admitting that, is there? Hello, I’m Elliot and I’m a capitalist.
The key is making money from doing what we love. For most people I know in our community, we’ve already achieved that — I’m hard-pressed to think of anyone who isn’t extremely passionate about working in our industry and I think it’s one of the most positive, unifying benefits we enjoy as a group of like-minded people — but side projects usually arise from another kind of passion: a passion for something other than what we do as our day jobs. Perhaps it’s because your clients are driving you mental and you need a break; perhaps it’s because you want to create something that is truly your own; perhaps it’s because you’re sick of seeing your online work disappear so fast and you want to try your hand at print in order to make a more permanent mark.
The three factors I listed there led me to create 8 Faces, a printed magazine about typography that started as a side project and is now a very significant part of my yearly output and income.
Like many things that prove fruitful, 8 Faces’ success was something of an accident, too. For a start, the magazine was never meant to be profitable; its only purpose at all was to scratch my own itch. Then, after the first issue took off and I realized how much time I needed to spend in order to make the next one decent, it became clear that I would have to cover more than just the production costs: I’d have to take time out from client work as well. Doing this meant I’d have to earn some money. Probably not enough to equate to the exact amount of time lost when I could be doing client work (not that you could ever describe time as being lost when you work on something you love), but enough to survive; for me to feel that I was getting paid while doing all of the work that 8 Faces entailed. The answer was to raise money through partnerships with some cool companies who were happy to be associated with my little project.
A sustainable business model
Business model! I can’t believe I just wrote those words! But a business model is really just a loose plan for how not to screw up. And all that stuff I wrote in the paragraph above about partnering with companies so I could get some money in while I put the magazine together? Well, that’s my business model.
If you’re making any product that has some sort of production cost, whether that’s physical print run expenses or up-front dev work to get an app built, covering those costs before you even release your product means that you’ll be in profit from the first copy you sell. This is no small point: production expenses are pretty much the only cost you’ll ever need to recoup, so having them covered before you launch anything is pretty much the best possible position in which you could place yourself. Happy days, as Jamie Oliver would say.
Obtaining these initial funds through partnerships has another benefit. Sure, it’s a form of advertising but, done right, your partners can potentially provide you with great content, too. In the case of 8 Faces, the ads look as nice as the rest of the magazine, and a couple of our partners also provide proper articles: genuinely meaningful, relevant, reader-pleasing articles at that. You’d be amazed at how many companies are willing to become partners and, as the old adage goes, if you don’t ask, you don’t get.
With profit comes responsibility
Don’t forget about the responsibility you have to your audience if you engage in a relationship with a partner or any type of advertiser: although I may have freely admitted my capitalist leanings, I’m still essentially a hairy hippy, and I feel that any partnership should be good for me as a publisher, good for the partner and — most importantly — good for the reader. Really, the key word here is relevance, and that’s where 99.9% of advertising fails abysmally.
(99.9% is not a scientific figure, but you know what I’m on about.)
The main grey area when a side project becomes profitable is how you share that profit, partly because — in my opinion, at least — the transition from non-profitable side project to relatively successful source of income can be a little blurred. Asking for help for nothing when there’s no money to be had is pretty normal, but sometimes it’s easy to get used to that free help even once you start making money. I believe the best approach is to ask for help with the promise that it will always be rewarded as soon as there’s money available. (Oh, god: this sounds like one of those nightmarish client proposals. It’s not, honest.) If you’re making something cool, people won’t mind helping out while you find your feet.
Events often think that they’re exempt from sharing profit. Perhaps that’s because many event organizers think they’re doing the speakers a favour rather than the other way around (that’s a whole separate article), but it’s shocking to see how many people seem to think they can profit from content-makers — speakers, for example — and yet not pay for that content. It was for this reason that Keir and I paid all of our speakers for our Insites: The Tour side project, which we ran back in July. We probably could’ve got away without paying them, especially as the gig was so informal, but it was the right thing to do.
In conclusion: money as a by-product
Let’s conclude by returning to the slightly problematic nature of money, because it’s the pivot on which your side project’s success can swing, regardless of whether you measure success by monetary gain. I would argue that success has nothing to do with profit — it’s about you being able to spend the time you want on the project. Unfortunately, that is almost always linked to money: money to pay yourself while you work on your dream idea; money to pay for more servers when your web app hits the big time; money to pay for efforts to get the word out there. The key, then, is to judge success on your own terms, and seek to generate as much money as you see fit, whether it’s purely to cover your running costs, or enough to buy a small country. There’s nothing wrong with profit, as long as you’re ethical about it. (Pro tip: if you’ve earned enough to buy a small country, you’ve probably been unethical along the way.)
The point at which individuals and companies fail — in the moral sense, for sure, but often in the competitive sense, too — is when money is the primary motivation. It should never be the primary motivation. If you’re not passionate enough about something to do it as an unprofitable side project, you shouldn’t be doing it all.
Earning money should be a by-product of doing what you love. And who doesn’t want to spend their life doing what they love? |

Creating Custom Font Stacks with Unicode-Range |
Any web designer or front-end developer worth their salt will be familiar with the CSS @font-face rule used for embedding fonts in a web page. We’ve all used it — either directly in our code ourselves, or via one of the web font services like Fontdeck, Typekit or Google Fonts.
If you’re like me, however, you’ll be used to just copying and pasting in a specific incantation of lines designed to get different formats of fonts working in different browsers, and may not have really explored all the capabilities of @font-face properties as defined by the spec.
One such property — the unicode-range descriptor — sounds pretty dull and is easily overlooked. It does, however, have some fairly interesting possibilities when put to use in creative ways.
Unicode-range
The unicode-range descriptor is designed to help when using fonts that don’t have full coverage of the characters used in a page. By adding a unicode-range property to a @font-face rule it is possible to specify the range of characters the font covers.
@font-face {
font-family: BBCBengali;
src: url(fonts/BBCBengali.ttf) format("opentype");
unicode-range: U+00-FF;
}
In this example, the font is to be used for characters in the range of U+00 to U+FF which runs from the unexciting control characters at the start of the Unicode table (symbols like the exclamation mark start at U+21) right through to ÿ at U+FF – the extent of the Basic Latin character range.
By adding multiple @font-face rules for the same family but with different ranges, you can build up complete coverage of the characters your page uses by using different fonts.
When I say that it’s possible to specify the range of characters the font covers, that’s true, but what you’re really doing with the unicode-range property is declaring which characters the font should be used for. This becomes interesting, because instead of merely working with the technical constraints of available characters in a given font, we can start picking and choosing characters to use and selectively mix fonts together.
The best available ampersand
A few years back, Dan Cederholm wrote a post encouraging designers to use the best available ampersand. Dan went on to outline how this can be achieved by wrapping our ampersands in a <span> element with a class applied:
<span class="amp">&</span>
A CSS rule can then be written to select the <span> and apply a different font:
span.amp {
font-family: Baskerville, Palatino, "Book Antiqua", serif;
}
That’s a perfectly serviceable technique, but the drawbacks are clear — you have to add extra markup which is borderline presentational, and you also have to be able to add that markup, which isn’t always possible when working with a CMS.
Perhaps we could do this with unicode-range.
A better best available ampersand
The Unicode code point for an ampersand is U+26, so the ampersand font stack above can be created like so:
@font-face {
font-family: 'Ampersand';
src: local('Baskerville'), local('Palatino'), local('Book Antiqua');
unicode-range: U+26;
}
What we’ve done here is specify a new family called Ampersand and created a font stack for it with the user’s locally installed copies of Baskerville, Palatino or Book Antiqua. We’ve then limited it to a single character range — the ampersand. Of course, those don’t need to be local fonts — they could be web font files, too. If you have a font with a really snazzy ampersand, go for your life.
We can then use that new family in a regular font stack.
h1 {
font-family: Ampersand, Arial, sans-serif;
}
With this in place, any <h1> elements in our page will use the Ampersand family (Baskerville, Palatino or Book Antiqua) for ampersands, and Arial for all other characters. If the user doesn’t have any of the Ampersand family fonts available, the ampersand will fall back to the next item in the font stack, Arial.
You didn’t think it was that easy, did you?
Oh, if only it were so. The problem comes, as ever, with the issue of browser support. The unicode-range property has good support in WebKit browsers (like Safari and Chrome, and the browsers on most popular smartphone platforms) and in recent versions of Internet Explorer. The big stumbling block comes in the form of Firefox, which has no support at all.
If you’re familiar with how CSS works when it comes to unsupported properties, you’ll know that if a browser encounters a property it doesn’t implement, it just skips that declaration and moves on to the next. That works perfectly for things like border-radius — if the browser can’t round off the corners, the declaration is skipped and the user sees square corners instead. Perfect.
Less perfect when it comes to unicode-range, because if no range is specified then the default is that the font is applied for all characters — the whole range. If you’re using a fancy font for flamboyant ampersands, you probably don’t want that applied to all your text if unicode-range isn’t supported. That would be bad. Really bad.
Ensuring good fallbacks
As ever, the trick is to make sure that there’s a sensible fallback in place if a browser doesn’t have support for whatever technology you’re trying to use. This is where being a super nerd about understanding the spec you’re working with really pays off.
We can make use of the rules of the CSS cascade to make sure that if unicode-range isn’t supported we get a sensible fallback font. What would be ideal is if we were able to follow up the @font-face rule with a second rule to override it if Unicode ranges aren’t implemented.
@font-face {
font-family: 'Ampersand';
src: local('Baskerville'), local('Palatino'), local('Book Antiqua');
unicode-range: U+26;
}
@font-face {
font-family: 'Ampersand';
src: local('Arial');
}
In theory, this code should make sense for all browsers. For those that support unicode-range the two rules become cumulative. They specify different ranges for the same family, and in WebKit browsers this has the expected result of using Arial for most characters, but Baskerville and friends for the ampersand. For browsers that don’t have support, the second rule should just supersede the first, setting the font to Arial.
Unfortunately, this code causes current versions of Firefox to freak out and use the first rule, applying Baskerville to the entire range. That’s both unexpected and unfortunate. Bad Firefox. On your rug.
If that doesn’t work, what can we do? Well, we know that if given a unicode-range Firefox will ignore the range and apply the font to all characters. That’s really what we’re trying to achieve. So what if we specified a range for the fallback font, but made sure it only covers some obscure high-value Unicode character we’re never going to use in our page? Then it wouldn’t affect the outcome for browsers that do support ranges.
@font-face {
font-family: 'Ampersand';
src: local('Baskerville'), local('Palatino'), local('Book Antiqua');
unicode-range: U+26;
}
@font-face {
/* Ampersand fallback font */
font-family: 'Ampersand';
src: local('Arial');
unicode-range: U+270C;
}
By specifying a range on the fallback font, Firefox appears to correctly override the first based on the cascade sort order. Browsers that do support ranges take the second rule in addition, and apply Arial for that obscure character we’re not using in any of our pages — U+270C.
So we get our nice ampersands in browsers that support unicode-range and, thanks to our styling of an obscure Unicode character, the font falls back to a perfectly acceptable Arial in browsers that do not offer support. Perfect!
That obscure character, my friends, is what Unicode defines as the VICTORY HAND.
✌
So, how can we use this?
Ampersands are a neat trick, and it works well in browsers that support ranges, but that’s not really the point of all this. Styling ampersands is fun, but they’re only really scratching the surface. Consider more involved examples, such as substituting a different font for numerals, or symbols, or even caps. Things certainly begin to get a bit more interesting.
How do you know what the codes are for different characters? Richard Ishida has a handy online conversion tool available where you can type in the characters and get the Unicode code points out the other end.
Of course, the fact remains that browser support for unicode-range is currently limited, so any application needs to have fallbacks that you’re still happy for a significant proportion of your visitors to see. In some cases, such as dedicated pages for mobile devices in an HTML-based phone app, this is immediately useful as support in WebKit browsers is already very good. In other cases, you’ll have to use your own best judgement based on your needs and audience.
One thing to keep in mind is that if you’re using web fonts, the entire font will be downloaded even if only one character is used. That said, the font shouldn’t be downloaded if none of the characters within the Unicode range are present in a given page.
As ever, there are pros and cons to using unicode-range as well as varied but increasing support in browsers. It remains a useful tool to understand and have in your toolkit for when the right moment comes along. |

Crafting the Front-end |
Much has been spoken and written recently about the virtues of craftsmanship in the context of web design and development. It seems that we as fabricators of the web are finally tiring of seeking out parallels between ourselves and architects, and are turning instead to the fabled specialist artisans.
Identifying oneself as a craftsman or craftswoman (let’s just say craftsperson from here onward) will likely be a trend of early 2012. In this pre-emptive strike, I’d like to expound on this movement as I feel it pertains to front-end development, and encourage care and understanding of the true qualities of craftsmanship (craftspersonship).
The core values
I’ll begin by defining craftspersonship. What distinguishes a craftsperson from a technician? Dictionaries tend to define a craftsperson as one who possesses great skill in a chosen field. The badge of a craftsperson for me, though, is a very special label that should be revered and used sparingly, only where it is truly deserved. A genuine craftsperson encompasses a few other key traits, far beyond raw skill, each of which must be learned and mastered.
A craftsperson has:
An appreciation of good work, in both the work of others and their own. And not just good as in ‘hey, that’s pretty neat’, I mean a goodness like a shining purity – the kind of good that feels right when you see it.
A belief in quality at every level: every facet of the craftsperson’s product is as crucial as any other, without exception, even those normally hidden from view.
Vision: an ability to visualize their path ahead, pre-empting the obstacles that may be encountered to plan a route around them.
A preference for simplicity: an almost Bauhausesque devotion to undecorated functionality, with no unjustifiable parts included.
Sincerity: producing work that speaks directly to its purpose with flawless clarity.
Only when you become a custodian of such values in your work can you consider calling yourself a craftsperson. Now let’s take a look at some steps we front-end developers can take on our journey of enlightenment toward craftspersonhood.
Speaking of the craftsman’s journey, be sure to watch out for the video of The Standardistas’ stellar talk at the Build 2011 conference titled The Journey, which should be online sometime soon.
Building your own toolbox
My grandfather was a carpenter and trained as a young apprentice under a master. After observing and practising the many foundation theories, principles and techniques of carpentry, he was tasked with creating his own set of woodworking tools, which he would use and maintain throughout his career. By going through the process of having to create his own tools, he would be connected at the most direct level with every piece of wood he touched, his tools being his own creations and extensions of his own skilled hands. The depth of his knowledge of these tools must have surpassed the intricate as he fathered, used, cleaned and repaired them, day in and day out over many years.
And so it should be, ideally, with all crafts. We must understand our tools right down to the most fundamental level. I firmly believe that a level of true craftsmanship cannot be reached while there exists a layer that remains not wholly understood between a creator and his canvas. Of course, our tools as front-end developers are somewhat more complex than those of other crafts – it may seem reasonable to require that a carpenter create his or her own set of chisels, but somewhat less so to ask a front-end developer to code their own CSS preprocessor, or design their own computer.
However, it is still vitally important that you understand how your tools work. This is particularly critical when it comes to things like preprocessors, libraries and frameworks which aim to save you time by automating common processes and functions. For the most part, anything that saves you time is a Good Thing™ but it cannot be stressed enough that using tools like these in earnest should be avoided until you understand exactly what they are doing for you (and, to an extent, how they are doing it).
In particular, you must understand any drawbacks to using your tools, and any shortcuts they may be taking on your behalf. I’m not suggesting that you steer clear of paid work until you’ve studied each of jQuery’s 9,266 lines of JavaScript source code but, all levity aside, it will further you on your journey to look at interesting or relevant bits of jQuery, and any other libraries you might want to use. Such libraries often directly link to corresponding sections of their source code on sites like GitHub from their official documentation. Better yet, they’re almost always written in high level languages (easy to read), so there’s no excuse not to don your pith helmet and go on something of an exploration. Any kind of tangential learning like this will drive you further toward becoming a true craftsperson, so keep an open mind and always be ready to step out of your comfort zone.
Downtime and tool honing
With any craft, it is essential to keep your tools in good condition, and a good idea to stay up-to-date with the latest equipment. This is especially true on the web, which, as we like to tell anyone who is still awake more than a minute after asking what it is that we do, advances at a phenomenal pace. A tool or technique that could be considered best practice this week might be the subject of haughty derision in a comment thread within six months.
I have little doubt that you already spend a chunk of time each day keeping up with the latest material from our industry’s finest Interblogs and Twittertubes, but do you honestly put aside time to collect bookmarks and code snippets from things you read into a slowly evolving toolbox? At @media in 2009, Simon Collison delivered a candid talk on his ‘Ultimate Package’. Those of us who didn’t flee the room anticipating a newfound and unwelcome intimacy with the contents of his trousers were shown how he maintained his own toolkit – a collection of files and folders all set up and ready to go for a new project. By maintaining a toolkit in this way, he has consistency across projects and a dependable base upon which to learn and improve.
The assembly and maintenance of such a personalized and familiar toolkit is probably as close as we will get to emulating the tool making stage of more traditional craft trades. Keep a master copy of your toolkit somewhere safe, making copies of it for new projects. When you learn of a way in which part of it can be improved, make changes to the master copy.
Simplicity through modularity
I believe that the user interfaces of all web applications should be thought of as being made up primarily of modular components. Modules in this context are patterns in design that appear repeatedly throughout the app. These can be small collections of elements, like a user profile summary box (profile picture, username, meta data), as well as atomic elements such as headings and list items.
Well-crafted front-end architectures have the ability to support this kind of repeating pattern as modules, with as close to no repetition of CSS (or JavaScript) as possible, and as close to no variations in HTML between instances as possible.
One of the most fundamental and well known tenets of software engineering is the DRY rule – don’t repeat yourself. It requires that “every piece of knowledge must have a single, unambiguous, authoritative representation within a system.”
As craftspeople, we must hold this rule dear and apply it to the modules we have identified in our site designs. The moment you commit a second style definition for a module, the quality of your output (the front-end code) takes a huge hit. There should only ever be one base style definition for each distinct module or component. Keep these in a separate, sacred place in your CSS. I use a _modules.scss Sass include file, imported near the top of my main CSS files.
Be sure, of course, to avoid making changes to this file lightly, as the smallest adjustment can affect multiple pages (hint: keep a structure list of which modules are used on which pages). Avoid the inevitable temptation to duplicate code late in the project. Sticking to this rule becomes more important the more complex the codebase becomes.
If you can stick to this rule, using sensible class names and consistent HTML, you can reach a joyous, self-fulfilling plateau stage in each project where you are assembling each interface from your own set of carefully crafted building blocks.
Old school markup
Let’s take a step back. Before we fret about creating a divinely pure modular CSS framework, we need to know the site’s design and what it is made of. The best way to gain this knowledge is to go old school. Print out every comp, mockup, wireframe, sketch or whatever you have. If there are sections of pages that are hidden until some user action takes place, or if the page has multiple states, be sure that you have everything that could become visible to the user on paper.
Once you have your wedge of paper designs, lay out all the pages on the floor, or stick them to the wall if you can, arranging them logically according to the site hierarchy, by user journey, or whatever guidelines make most sense to you. Once you have the site laid out before you, study it for a while, familiarizing yourself with every part of every interface. This will eliminate nasty surprises late in the project when you realize you’ve duplicated something, or left an interface on the drawing board altogether.
Now that you know the site like it’s your best friend, get out your pens or pencils of choice and attack it. Mark it up like there’s no tomorrow. Pretend you’re a spy trying to identify communications from an enemy network hiding their messages in newspapers. Look for patterns and similarities, drawing circles around them. These are your modules. Start also highlighting the differences between each instance of these modules, working out which is the most basic or common type that will become the base definition from which all other representations are extended.
This simple but empowering exercise will equip you for your task of actually crafting, instead of just building, the front-end. Without the knowledge gained from this kind of research phase, you will be blundering forward, improvising as best you can, but ultimately making quality-compromising mistakes that could have been avoided.
For more on this theme, read Anna Debenham’s Front-end Style Guides which recommends a similar process, and the sublime idea of extending this into a guide to refer to during development and beyond.
Design homogeneity
Moving forward again, you now have your modules defined and things are looking good. I mentioned that many instances of these modules will carry minor differences. These differences must be given significant thinking time, and discussion time with your designer(s).
It should be common knowledge by now that successful software projects are not the product of distinct design and build phases with little or no bidirectional feedback. The crucial nature of the designer-developer relationship has been covered in depth this year by Paul Robert Lloyd, and a joint effort from both teams throughout the project lifecycle is pivotal to your ability to craft and ship successful products.
This relationship comes into play when you’re well into the development of the site, and you start noticing these differences between instances of modules (they’ll start to stand out very clearly to you and your carefully regimented modular CSS system). Before you start overriding your base styles, question the differences with the designer to work out why they exist. Perhaps they are required and are important to their context, but perhaps they were oversights from earlier design revisions, or simple mistakes.
The craftsperson’s gland
As you grow towards the levels of expertise and experience where you can proudly and honestly consider yourself a craftsperson, you will find that you steadily develop what initially feels like a kind of sixth sense. I think of it more as a new hormonal gland, secreting into your bloodstream a powerful messenger chemical that can either reward or punish your brain. This gland is connected directly to your core understanding of what good quality work looks and feels like, an understanding that itself improves with experience.
This gland will make itself known to you in two ways. First, when you solve a problem in a beautifully elegant way with clean and unobtrusive code that looks good and just feels right, your craftsperson’s gland will ooze something delicious that makes your brain and soul glow from the inside out. You will beam triumphantly at the succinct lines of code on your computer display before bounding outside with a spring in your step to swim up glittering rainbows and kiss soft fluffy puppies.
The second way that you may become aware of your craftsperson’s gland, though, is somewhat less pleasurable. In an alternate reality, your parallel self is faced with the same problem, but decides to take a shortcut and get around it by some dubious means – the kind of technical method that the words hack, kludge and bodge are reserved for. As soon as you have done this, or even as you are doing it, your craftsperson’s gland will damn well let you know that you took the wrong fork in the road. As your craftsperson’s gland begins to secrete a toxic pus, you will at first become entranced into a vacant stare at the monstrous mess you are considering unleashing upon your site’s visitors, before writhing in the horrible agony of an itch that can never be scratched, and a feeling of being coated with the devil’s own deep and penetrating filth that no shower will ever cleanse.
Perhaps I exaggerate slightly, but it is no overstatement to suggest that you will find yourself being guided by proverbial angels and demons perched on opposite shoulders, or a whispering voice inside your head. If you harness this sense, sharpening it as if it were another tool in your kit and letting it guide or at least advise your decision making, you will transcend the rocky realm of random trial and error when faced with problems, and tend toward the right answers instinctively.
This gland can also empower your ability to assess your own work, becoming a judge before whom all your work is cross-examined. A good craftsperson regularly takes a step back from their work, and questions every facet of their product for its precise alignment with their core values of quality and sincerity, and even the very necessity of each component.
The wrapping
By now, you may be thinking that I take this kind of thing far too seriously, but to terrify you further, I haven’t even shared the half of it. Hopefully, though, this gives you an idea of the kind of levels of professionalism and dedication that it should take to get you on your way to becoming a craftsperson. It’s a level of accomplishment and ability toward which we all should strive, both for our personal fulfilment and the betterment of the products we use daily. I look forward to seeing your finely crafted work throughout 2012. |

There’s No Formula for Great Designs |
Before he combined them with fluid images and CSS3 media queries to coin responsive design, Ethan Marcotte described fluid grids — one of the most enjoyable parts of responsive design. Enjoyable that is, if you like working with math(s). But fluid grids aren’t perfect and, unless we’re careful when applying them, they can sometimes result in a design that feels disconnected.
Recapping fluid grids
If you haven’t read Ethan’s Fluid Grids, now would be a good time to do that. It centres around a simple formula for converting pixel widths to percentages:
(target ÷ context) × 100 = result
How does that work in practice? Well, take that Fireworks or Photoshop comp you’re working on (I call them static design visuals, or just visuals.) Of course, everything on that visual — column divisions, inline images, navigation elements, everything — is measured in pixels. Now:
Pick something in the visual and measure its width. That’s our target.
Take that target measurement and divide it by the width of its parent (context).
Multiply what you’ve got by 100 (shift two decimal places).
What you’re left with is a percentage width to drop into your style sheets.
For example, divide this 300px wide sidebar division by its 948px parent and then multiply by 100: your original 300px is neatly converted to 31.646%.
.content-sub {
width : 31.646%; /* 300px ÷ 948px = .31646 */ }
That formula makes it surprisingly simple for even die-hard fixed width aficionados to convert their visuals to percentage-based, fluid layouts.
It’s a handy formula for those who still design using static visuals, and downright essential for those situations where one person in an organization designs in Fireworks or Photoshop and another develops with CSS. Why?
Well, although I think that designing in a browser makes the best sense — particularly when designing for multiple devices — I’ll wager most designers still make visuals in Fireworks or Photoshop and use them for demonstrations and get feedback and sign-off. That’s OK. If you haven’t made the transition to content-out designing in a browser yet, the fluid grids formula helps you carry on pushing pixels a while longer.
You can carry on moving pixel width measurements from your visuals to your style sheets, too, in the same way you always have. You can be precise to the pixel and even apply a grid image as a CSS background to help you keep everything lined up perfectly.
Once you’re done, and the fixed width layout in the browser matches your visual, loop back through your style sheets and convert those pixels to percentages using the fluid grids formula. With very little extra work, you’ll have a fluid implementation of your fixed width layout.
The fluid grids formula is simple and incredibly effective, but not long after I started working responsively I realized that the formula shouldn’t (always) be a one-fix, set-and-forget calculation. I noticed that unless we compensate for problems it sometimes creates, the result can be a disconnected design.
Staying connected
Good design relies on connectedness, a feeling of natural balance between elements and the grid they’re placed on. Give an element greater prominence or position in a visual hierarchy and you can fundamentally alter the balance and sometimes the meaning of a design.
Different from a browser’s page zooming feature — where images, text and overall layout change size by the same ratio — fluid grids flex a layout in response to a window or device width. Columns expand and contract, and within them fluid media (images and videos) can also change size. This can be one of the most impressive demonstrations of responsive design.
But not every element within a fluid grid can change size along with the window or device width. For example, type size and leading won’t change along with a column’s width.
When columns and elements within them change width, all too easily a visual hierarchy can be broken and along with it the relationship between element sizes and the outer window or viewport. This can happen quickly if you make just one set of fluid grid calculations and use those percentages across every screen width, from smartphones through tablets and up to large desktops.
The answer? Make several sets of fluid grids calculations, each one at a significant window or device width breakpoint. Then apply those new percentages, when needed, to help keep elements in proportion and maintain balance and connectedness. Here’s how I work.
Avoiding disconnection
I’ve never been entirely happy with grid frameworks such as the 960 Grid System, so I start almost every project by creating a custom grid to inform my layout decisions. Here’s a plain version of a grid from a recent project that I’ll use as an illustration.
This project’s grid comprises 84px columns and 24px gutters. This creates an odd number of columns at common tablet and desktop widths, and allows for 300px fixed width assets — useful when I need to fit advertising into a desktop layout’s sidebar.
Showing common advertising sizes (Larger image)
For this project I chose three 320 and Up breakpoints above 320px and, after placing as many columns as would fit those breakpoint widths, I derived three content widths:
Breakpoint
Columns
Content width
768px
7
732px
992px
9
948px
1,382px
13
1,380px
Here’s my grid again, this time with pixel measurements and breakpoints overlaid.
Showing pixel measurements and breakpoints (Larger image)
Now cast your mind back to the fluid grids calculation I made earlier. I divided a 300px element by 948px and arrived at 31.646%. For some elements it’s possible to use that percentage across all screen widths, but others will feel too small in relation to a narrower 768px and too large inside 1,380px.
To help maintain connectedness, I make a set of fluid grids calculations based on each of the content widths I established earlier. Now I can shift an element’s percentage width up or down when I switch to a new breakpoint and content width. For example:
300px is 40.984% of 732px
300px is 31.646% of 948px
300px is 21.739% of 1,380px
I’ll add all those fluid grid percentages to my grid image and save it for quick reference.
Showing percentages at all breakpoints (Larger image)
Then I can apply those different percentage widths to elements at each breakpoint using CSS3 media queries. For example, that sidebar division again:
/* 732px, 7-column width */
@media only screen and (min-width: 768px) {
.content-sub {
width : 40.983%; /* 300px ÷ 732px = .40983 */ }
}
/* 948px, 9-column width */
@media only screen and (min-width: 992px) {
.content-sub {
width : 31.645%; /* 300px ÷ 948px = .31645 */ }
}
/* 1380px, 13-column width */
@media only screen and (min-width: 1382px) {
.content-sub {
width : 21.739%; /* 300px ÷ 1380px = .21739 */ }
}
The number of changes you make to a layout at different breakpoints will, of course, depend on the specifics of the design you’re working on. Yes, this is additional work, but the result will be a layout that feels better balanced and within which elements remain in harmony with each other while they respond to new screen or device widths.
Putting the design in responsive web design
Until now, many of the conversations around responsive web design have been about aspects of technical implementation, rather than design. I believe we’re only beginning to understand what’s involved in designing responsively. In future, we’ll likely be making design decisions not just about proportions but also about responsive typography. We’ll also need to learn how to adapt our designs to device characteristics such as touch targets and more.
Sometimes we’ll make decisions to improve function, other times because they make a design ‘feel’ right. You’ll know when you’ve made a right decision. You’ll feel it.
After all, there really is no formula for making great designs. |

Adaptive Images for Responsive Designs |
So you’ve been building some responsive designs and you’ve been working through your checklist of things to do:
You started with the content and designed around it, with mobile in mind first.
You’ve gone liquid and there’s nary a px value in sight; % is your weapon of choice now.
You’ve baked in a few media queries to adapt your layout and tweak your design at different window widths.
You’ve made your images scale to the container width using the fluid Image technique.
You’ve even done the same for your videos using a nifty bit of JavaScript.
You’ve done a good job so pat yourself on the back. But there’s still a problem and it’s as tricky as it is important: image resolutions.
HTML has an <img> problem
CSS is great at adapting a website design to different window sizes – it allows you not only to tweak layout but also to send rescaled versions of the design’s images. And you want to do that because, after all, a smartphone does not need a 1,900-pixel background image1.
HTML is less great. In the same way that you don’t want CSS background images to be larger than required, you don’t want that happening with <img>s either. A smartphone only needs a small image but desktop users need a large one. Unfortunately <img>s can’t adapt like CSS, so what do we do?
Well, you could just use a high resolution image and the fluid image technique would scale it down to fit the viewport; but that’s sending an image five or six times the file size that’s really needed, which makes it slow to download and unpleasant to use. Smartphones are pretty impressive devices – my ancient iPhone 3G is more powerful in every way than my first proper computer – but they’re still terribly slow in comparison to today’s desktop machines. Sending a massive image means it has to be manipulated in memory and redrawn as you scroll. You’ll find phones rapidly run out of RAM and slow to a crawl.
Well, OK. You went mobile first with everything else so why not put in mobile resolution <img>s too? Because even though mobile devices are rapidly gaining share in your analytics stats, they’re still not likely to be the major share of your user base. I don’t think desktop users would be happy with pokey little mobile resolution images, do you? What we need are adaptive images.
Adaptive image techniques
There are a number of possible solutions, each with pros and cons, and it’s not as simple to find a graceful solution as you might expect.
Your first thought might be to use JavaScript to trawl through the markup and rewrite the source attribute. That’ll get you the right end result, but it’ll have done it in a way you absolutely don’t want. That’s because of the way browsers load resources. It starts to load the HTML and builds the page on-the-fly; as soon as it finds an <img> element it immediately asks the server for that image. After the HTML has finished loading, the JavaScript will run, change the src attribute, and then the browser will request that new image too. Not instead of, but as well as. Not good: that’s added more bloat instead of cutting it.
Plain JavaScript is out then, which is a problem, because what other tools do we have to work with as web designers? Let’s ignore that for now and I’ll outline another issue with the concept of serving different resolution images for different window widths: a basic file management problem. To request a different image, that image has to exist on the server. How’s it going to get there? That’s not a trivial problem, especially if you have non-technical users that update content through a CMS. Let’s say you solve that – do you plan on a simple binary switch: big image|little image? Is that really efficient or future-proof? What happens if you have an archive of existing content that needs to behave this way? Can you apply such a solution to existing content or markup?
There’s a detailed round-up of potential techniques for solving the adaptive images problem over at the Cloud Four blog if you fancy a dig around exploring all the options currently available. But I’m here to show you what I think is the most flexible and easy to implement solution, so here we are.
Adaptive Images
Adaptive Images aims to mitigate most of the issues surrounding the problems of bringing the venerable <img> tag into the 21st century. And it works by leaving that tag completely alone – just add that desktop resolution image into the markup as you’ve been doing for years now. We’ll fix it using secret magic techniques and bottled pixie dreams. Well, fine: with one .htaccess file, one small PHP file and one line of JavaScript. But you’re killing the mystique with that kind of talk.
So, what does this solution do?
It allows <img>s to adapt to the same break points you use in your media queries, giving granular control in the same way you get with your CSS.
It installs on your server in five minutes or less and after that is automatic and you don’t need to do anything.
It generates its own rescaled images on the server and doesn’t require markup changes, so you can apply it to existing web content.
If you wish, it will make all of your images go mobile-first (just in case that’s what you want if JavaScript and cookies aren’t available).
Sound good? I hope so. Here’s what you do.
Setting up and rolling out
I’ll assume you have some basic server knowledge along with that wealth of front-end wisdom exploding out of your head: that you know not to overwrite any existing .htaccess file for example, and how to set file permissions on your server. Feeling up to it? Excellent.
Download the latest version of Adaptive Images either from the website or from the GitHub repository.
Upload the included .htaccess and adaptive-images.php files into the root folder of your website.
Create a directory called ai-cache and make sure the server can write to it (CHMOD 755 should do it).
Add the following line of JavaScript into the <head> of your site:
<script>document.cookie='resolution='+Math.max(screen.width,screen.height)+'; path=/‘;</script>
That’s it, unless you want to tweak the default settings. You likely do, but essentially you’re already up and running.
How it works
Adaptive Images does a number of things depending on the scenario the script has to handle, but here’s a basic overview of what it does when you load a page running it:
A session cookie is written with the value of the visitor’s screen size in pixels.
The HTML encounters an <img> tag and sends a request to the server for that image. It also sends the cookie, because that’s how browsers work.
Apache sits on the server and receives the request for the image. Apache then has a look in the .htaccess file to see if there are any special instructions for files in the requested URL.
There are! The .htaccess says “Hey, server! Any request you get for a JPG, GIF or PNG file just send to the adaptive-images.php file instead.”
The PHP file then does some intelligent thinking which can cover a number of scenarios, but I’ll illustrate one path that can happen:
The PHP file looks for the cookie and finds out that the user has a maximum screen width of 480px.
The PHP has a look at the available media query sizes that were configured and decides which one matches the user’s device.
It then has a look inside the /ai-cache/480/ folder to see if a rescaled image already exists there.
We’ll pretend it doesn’t – the PHP then goes to the actual requested URI and finds that the original file does exist.
It has a look to see how wide that image is. If it’s already smaller than the user’s screen width it sends it along and stops there. But, let’s pretend the image is 1,000px wide.
The PHP then resizes the image and saves it into the /ai-cache/480 folder ready for the next time someone needs it.
It also does a few other things when needs arise, for example:
It sends images with a cache header field that tells proxies not to cache the image, while telling browsers they should. This avoids problems with proxy servers and network caching systems grabbing the wrong image and storing it.
It handles cases where there isn’t a cookie set, and you can choose whether to then send the mobile version or the largest configured media query size.
It compares timestamps between the source image and the generated cache image – to ensure that if the source image gets updated, the old cached file won’t be sent.
Customizing
There are a few options you can customize if you don’t like the default values. By looking in the PHP’s configuration section at the top of the file, you can:
Set the resolution breakpoints to match your media query break points.
Change the name and location of the ai-cache folder.
Change the quality level any generated JPG images are saved at.
Have it perform a subtle sharpen on rescaled images to help keep detail.
Toggle whether you want it to compare the files in the cache folder with the source ones or not.
Set how long the browser should cache the images for.
Switch between a mobile-first or desktop-first approach when a cookie isn’t found.
More importantly, you probably want to omit a few folders from the AI behaviour. You don’t need or want it resizing the images you’re using in your CSS, for example. That’s fine – just open up the .htaccess file and follow the instructions to list any directories you want AI to ignore. Or, if you’re a dab hand at RewriteRules you can remove the exclamation mark at the start of the rule and it’ll only apply AI behaviour to a given list of folders.
Caveats
As I mentioned, I think this is one of the most flexible, future-proof, retrofittable and easy to use solutions available today. But, there are problems with this approach as there are with all of the ones I’ve seen so far.
This is a PHP solution
I wish I was smarter and knew some fancy modern languages the cool kids discuss at parties, but I don’t. So, you need PHP on your server. That said, Adaptive Images has a Creative Commons licence2 and I would welcome anyone to contribute a port of the code3.
Content delivery networks
Adaptive Images relies on the server being able to: intercept requests for images; do some logic; and send one of a given number of responses. Content delivery networks are generally dumb caches, and they won’t allow that to happen. Adaptive Images will not work if you’re using a CDN to deliver your website.
A minor but interesting cookie issue.
As Yoav Weiss pointed out in his article Preloaders, cookies and race conditions, there is no way to guarantee that a cookie will be set before images are requested – even though the JavaScript that sets the cookie is loaded by the browser before it finds any <img> tags. That could mean images being requested without a cookie being available. Adaptive Images has a two-fold mechanism to avoid this being a problem:
The $mobile_first toggle allows you to choose what to send to a browser if a cookie isn’t set. If FALSE then it will send the highest configured resolution; if TRUE it will send the lowest.
Even if set to TRUE, Adaptive Images checks the User Agent String. If it discovers the user is on a desktop environment, it will override $mobile_first and set it to FALSE.
This means that if $mobile_first is set to TRUE and the user was unlucky (their browser didn’t write the cookie fast enough), mobile devices will be supplied with the smallest image, and desktop devices will get the largest.
The best way to get a cookie written is to use JavaScript as I’ve explained above, because it’s the fastest way. However, for those that want it, there is a JavaScript-free method which uses CSS and a bogus PHP ‘image’ to set the cookie. A word of caution: because it requests an external file, this method is slower than the JavaScript one, and it is very likely that the cookie won’t be set until after images have been requested.
The future
For today, this is a pretty good solution. It works, and as it doesn’t interfere with your markup or source material in any way, the process is non-destructive. If a future solution is superior, you can just remove the Adaptive Images files and you’re good to go – you’d never know AI had been there.
However, this isn’t really a long-term solution, not least because of the intermittent problem of the cookie and image request race condition. What we really need are a number of standardized ways to handle this in the future.
First, we could do with browsers sending far more information about the user’s environment along with each HTTP request (device size, connection speed, pixel density, etc.), because the way things work now is no longer fit for purpose. The web now is a much broader entity used on far more diverse devices than when these technologies were dreamed up, and we absolutely require the server to have better knowledge about device capabilities than is currently possible. Relying on cookies to do this job doesn’t cut it, and the User Agent String is a complete mess incapable of fulfilling the various purposes we are forced to hijack it for.
Secondly, we need a W3C-backed markup level solution to supply semantically different content at different resolutions, not just rescaled versions of the same content as Adaptive Images does.
I hope you’ve found this interesting and will find Adaptive Images useful.
Footnotes
1 While I’m talking about preventing smartphones from downloading resources they don’t need: you should be careful of your media query construction if you want to stop WebKit downloading all the images in all of the CSS files.
2 Adaptive Images has a very broad Creative Commons licence and I warmly welcome feedback and community contributions via the GitHub repository.
3 There is a ColdFusion port of an older version of Adaptive Images. I do not have anything to do with ported versions of Adaptive Images. |

Context First: Web Strategy in Four Handy Ws |
Many, many years ago, before web design became my proper job, I trained and worked as a journalist. I studied publishing in London and spent three fun years learning how to take a few little nuggets of information and turn them into a story. I learned a bunch of stuff that has all been a huge help to my design career. Flatplanning, layout, typographic theory. All of these disciplines have since translated really well to web design, but without doubt the most useful thing I learned was how to ask difficult questions.
Pretty much from day one of journalism school they hammer into you the importance of the Five Ws. Five disarmingly simple lines of enquiry that eloquently manage to provide the meat of any decent story. And with alliteration thrown in too. For a young journo, it’s almost too good to be true.
Who? What? Where? When? Why? It seems so obvious to almost be trite but, fundamentally, any story that manages to answer those questions for the reader is doing a pretty good job. You’ll probably have noticed feeling underwhelmed by certain news pieces in the past – disappointed, like something was missing. Some irritating oversight that really lets the story down. No doubt it was one of the Ws – those innocuous little suckers are generally only noticeable by their absence, but they sure get missed when they’re not there.
Question everything
I’ve always been curious. An inveterate tinkerer with things and asker of dopey questions, often to the point of abject annoyance for anyone unfortunate enough to have ended up in my line of fire. So, naturally, the Five Ws started drifting into other areas of my life. I’d scrutinize everything, trying to justify or explain my rationale using these Ws, but I’d also find myself ripping apart the stuff that clearly couldn’t justify itself against the same criteria.
So when I started working as a designer I applied the same logic and, sure enough, the Ws pretty much mapped to the exact same needs we had for gathering requirements at the start of a project. It seemed so obvious, such a simple way to establish the purpose of a product. What was it for? Why we were making it? And, of course, who were we making it for? It forced clients to stop and think, when really what they wanted was to get going and see something shiny. Sometimes that was a tricky conversation to have, but it’s no coincidence that those who got it also understood the value of strategy and went on to have good solid products, while those that didn’t often ended up with arrogantly insular and very shiny but ultimately unsatisfying and expendable products. Empty vessels make the most noise and all that…
Content first
I was both surprised and pleased when the whole content first idea started to rear its head a couple of years back. Pleased, because without doubt it’s absolutely the right way to work. And surprised, because personally it’s always been the way I’ve done it – I wasn’t aware there was even an alternative way. Content in some form or another is the whole reason we were making the things we were making. I can’t even imagine how you’d start figuring out what a site needs to do, how it should be structured, or how it should look without a really good idea of what that content might be. It baffles me still that this was somehow news to a lot of people. What on earth were they doing? Design without purpose is just folly, surely?
It’s great to see the idea gaining momentum but, having watched it unfold, it occurred to me recently that although it’s fantastic to see a tangible shift in thinking – away from those bleak times, where making things up was somehow deemed an appropriate way to do things – there’s now a new bad guy in town.
With any buzzword solution of the moment, there’s always a catch, and it seems like some have taken the content first approach a little too literally. By which I mean, it’s literally the first thing they do. The project starts, there’s a very cursory nod towards gathering requirements, and off they go, cranking content. Writing copy, making video, commissioning illustrations.
All that’s happened is that the ‘making stuff up’ part has shifted along the line, away from layout and UI, back to the content.
Starting is too easy
I can’t remember where I first heard that phrase, but it’s a great sentiment which applies to so much of what we do on the web. The medium is so accessible and to an extent disposable; throwing things together quickly carries far less burden than in any other industry. We’re used to tweaking as we go, changing bits, iterating things into shape. The ubiquitous beta tag has become the ultimate caveat, and has made the unfinished and unpolished acceptable. Of course, that can work brilliantly in some circumstances. Occasionally, a product offers such a paradigm shift it’s beyond the level of deep planning and prelaunch finessing we’d ideally like. But, in the main, for most client sites we work on, there really is no excuse not to do things properly. To ask the tricky questions, to challenge preconceptions and really understand the Ws behind the products we’re making before we even start.
The four Ws
For product definition, only four of the five Ws really apply, although there’s a lot of discussion around the idea of when being an influencing factor. For example, the context of a user’s engagement with your product is something you can make a call on depending on the specifics of the project.
So, here’s my take on the four essential Ws. I’ll point out here that, of course, these are not intended to be autocratic dictums. Your needs may differ, your clients’ needs may differ, but these four starting points will get you pretty close to where you need to be.
Who
It’s surprising just how many projects start without a real understanding of the intended audience. Many clients think they have an idea, but without really knowing – it’s presumptive at best, and we all know what presumption is the mother of, right? Of course, we can’t know our audiences in the same way a small shop owner might know their customers. But we can at least strive to find out what type of people are likely to be using the product. I’m not talking about deep user research. That should come later.
These are the absolute basics. What’s the context for their visit? How informed are they? What’s their level of comprehension? Are they able to self-identify and relate to categories you have created? I could go on, and it changes on a per-project basis. You’ll only find this out by speaking to them, if not in person, then indirectly through surveys, questionnaires or polls. The mechanism is less important than actually reaching out and engaging with them, because without that understanding it’s impossible to start to design with any empathy.
What
Once you become deeply involved directly with a product or service, it’s notoriously difficult to see things as an outsider would. You learn the thing inside and out, you develop shortcuts and internal phraseology. Colloquialisms creep in. You become too close. So it’s no surprise when clients sometimes struggle to explain what it is their product actually does in a way that others can understand.
Often products are complex but, really, the core reasons behind someone wanting to use that product are very simple. There’s a value proposition for the customer and, if they choose to engage with it, there’s a value exchange. If that proposition or exchange isn’t transparent, then people become confused and will likely go elsewhere. Make sure both your client and you really understand what that proposition is and, in turn, what the expected exchange should be. In a nutshell: what is the intended outcome of that engagement? Often the best way to do this is strip everything back to nothing. Verbosity is rife on the web. Just because it’s easy to create content, that shouldn’t be a reason to do so. Figure out what the value proposition is and then reintroduce content elements that genuinely help explain or present that to a level that is appropriate for the audience.
Why
In advertising, they talk about the truths behind a product or service. Truths can be both tangible or abstract, but the most important part is the resonance those truths hit with a customer. In a digital product or service those truths are often exposed as benefits. Why is this what I need? Why will it work for me? Why should I trust you? The why is one of the more fluffy Ws, yet it’s such an important one to nail. Clients can get prickly when you ask them to justify the why behind their product, but it’s a fantastic way to make sure the value proposition is clear, realistic and meets with the expectations of both client and customer.
It’s our job as designers to question things: we’re not just a pair of hands for clients. Just recently I spoke to a potential client about a site for his business. I asked him why people would use his product and also why his product seemed so fractured in its direction. He couldnt answer that question so, instead of ploughing on regardless, he went back to his directors and is now re-evaluating that business. It was awkward but he thanked me and hopefully he’ll have a better product as a result.
Where
In this instance, where is not so much a geographical thing, although in some cases that level of context may indeed become a influencing factor… The where we’re talking about here is the position of the product in relation to others around it. By looking at competitors or similar services around the one you are designing, you can start to get a sense for many of the things that are otherwise hard to pin down or have yet to be defined. For example, in a collection of sites all selling cars, where does yours fit most closely? Where are the overlaps? How are they communicating to their customers? How is the product range presented or categorized?
It’s good to look around and see how others are doing it. Not in a quest for homogeneity but more to reference or to avoid certain patterns that may or may not make sense for your own particular product. Clients often strive to be different for the sake of it. They feel they need to provide distinction by going against the flow a bit. We know different. We know users love convention. They embrace familiar mental models. They’re comfortable with things that they’ve experienced elsewhere. By showing your client that position is a vital part of their strategy, you can help shape their product into something great.
To conclude
So there we have it – the four Ws. Each part tells a different and vital part of the story you need to be able to make a really good product. It might sound like a lot of work, particularly when the client is breathing down your neck expecting to see things, but without those pieces in place, the story you’re building your product on, and the content that you’re creating to form that product can only ever fit into one genre. Fiction. |

Your jQuery: Now With 67% Less Suck |
Fun fact: more websites are now using jQuery than Flash.
jQuery is an amazing tool that’s made JavaScript accessible to developers and designers of all levels of experience. However, as Spiderman taught us, “with great power comes great responsibility.” The unfortunate downside to jQuery is that while it makes it easy to write JavaScript, it makes it easy to write really really f*&#ing bad JavaScript. Scripts that slow down page load, unresponsive user interfaces, and spaghetti code knotted so deep that it should come with a bottle of whiskey for the next sucker developer that has to work on it.
This becomes more important for those of us who have yet to move into the magical fairy wonderland where none of our clients or users view our pages in Internet Explorer. The IE JavaScript engine moves at the speed of an advancing glacier compared to more modern browsers, so optimizing our code for performance takes on an even higher level of urgency.
Thankfully, there are a few very simple things anyone can add into their jQuery workflow that can clear up a lot of basic problems. When undertaking code reviews, three of the areas where I consistently see the biggest problems are: inefficient selectors; poor event delegation; and clunky DOM manipulation. We’ll tackle all three of these and hopefully you’ll walk away with some new jQuery batarangs to toss around in your next project.
Selector optimization
Selector speed: fast or slow?
Saying that the power behind jQuery comes from its ability to select DOM elements and act on them is like saying that Photoshop is a really good tool for selecting pixels on screen and making them change color – it’s a bit of a gross oversimplification, but the fact remains that jQuery gives us a ton of ways to choose which element or elements in a page we want to work with. However, a surprising number of web developers are unaware that all selectors are not created equal; in fact, it’s incredible just how drastic the performance difference can be between two selectors that, at first glance, appear nearly identical. For instance, consider these two ways of selecting all paragraph tags inside a <div> with an ID.
$("#id p");
$("#id").find("p");
Would it surprise you to learn that the second way can be more than twice as fast as the first? Knowing which selectors outperform others (and why) is a pretty key building block in making sure your code runs well and doesn’t frustrate your users waiting for things to happen.
There are many different ways to select elements using jQuery, but the most common ways can be basically broken down into five different methods. In order, roughly, from fastest to slowest, these are:
$("#id");
This is without a doubt the fastest selector jQuery provides because it maps directly to the native document.getElementbyId() JavaScript method. If possible, the selectors listed below should be prefaced with an ID selector in conjunction with jQuery’s .find() method to limit the scope of the page that has to be searched (as in the $("#id").find("p") example shown above).
$("p");, $("input");, $("form"); and so on
Selecting elements by tag name is also fast, since it maps directly to the native document.getElementsByTagname() method.
$(".class");
Selecting by class name is a little trickier. While still performing very well in modern browsers, it can cause some pretty significant slowdowns in IE8 and below. Why? IE9 was the first IE version to support the native document.getElementsByClassName() JavaScript method. Older browsers have to resort to using much slower DOM-scraping methods that can really impact performance.
$("[attribute=value]");
There is no native JavaScript method for this selector to use, so the only way that jQuery can perform the search is by crawling the entire DOM looking for matches. Modern browsers that support the querySelectorAll() method will perform better in certain cases (Opera, especially, runs these searches much faster than any other browser) but, generally speaking, this type of selector is Slowey McSlowersons.
$(":hidden");
Like attribute selectors, there is no native JavaScript method for this one to use. Pseudo-selectors can be painfully slow since the selector has to be run against every element in your search space. Again, modern browsers with querySelectorAll() will perform slightly better here, but try to avoid these if at all possible. If you must use one, try to limit the search space to a specific portion of the page: $("#list").find(":hidden");
But, hey, proof is in the performance testing, right? It just so happens that said proof is sitting right here. Be sure to notice the class selector numbers beside IE7 and 8 compared to other browsers and then wonder how the people on the IE team at Microsoft manage to sleep at night. Yikes.
Chaining
Almost all jQuery methods return a jQuery object. This means that when a method is run, its results are returned and you can continue executing more methods on them. Rather than writing out the same selector multiple times over, just making a selection once allows multiple actions to be run on it.
Without chaining
$("#object").addClass("active");
$("#object").css("color","#f0f");
$("#object").height(300);
With chaining
$("#object").addClass("active").css("color", "#f0f").height(300);
This has the dual effect of making your code shorter and faster. Chained methods will be slightly faster than multiple methods made on a cached selector, and both ways will be much faster than multiple methods made on non-cached selectors. Wait… “cached selector”? What is this new devilry?
Caching
Another easy way to speed up your code that seems to be a mystery to developers is the idea of caching your selectors. Think of how many times you end up writing the same selector over and over again in any project. Every $(".element") selector has to search the entire DOM each time, regardless of whether or not that selector had been previously run. Running the selection once and then storing the results in a variable means that the DOM only has to be searched once. Once the results of a selector have been cached, you can do anything with them.
First, run your search (here we’re selecting all of the <li> elements inside <ul id="blocks">):
var blocks = $("#blocks").find("li");
Now, you can use the blocks variable wherever you want without having to search the DOM every time.
$("#hideBlocks").click(function() {
blocks.fadeOut();
});
$("#showBlocks").click(function() {
blocks.fadeIn();
});
My advice? Any selector that gets run more than once should be cached. This jsperf test shows just how much faster a cached selector runs compared to a non-cached one (and even throws some chaining love in to boot).
Event delegation
Event listeners cost memory. In complex websites and apps it’s not uncommon to have a lot of event listeners floating around, and thankfully jQuery provides some really easy methods for handling event listeners efficiently through delegation.
In a bit of an extreme example, imagine a situation where a 10×10 cell table needs to have an event listener on each cell; let’s say that clicking on a cell adds or removes a class that defines the cell’s background color. A typical way that this might be written (and something I’ve often seen during code reviews) is like so:
$('table').find('td').click(function() {
$(this).toggleClass('active');
});
jQuery 1.7 has provided us with a new event listener method, .on(). It acts as a utility that wraps all of jQuery’s previous event listeners into one convenient method, and the way you write it determines how it behaves. To rewrite the above .click() example using .on(), we’d simply do the following:
$('table').find('td').on('click',function() {
$(this).toggleClass('active');
});
Simple enough, right? Sure, but the problem here is that we’re still binding one hundred event listeners to our page, one to each individual table cell. A far better way to do things is to create one event listener on the table itself that listens for events inside it. Since the majority of events bubble up the DOM tree, we can bind a single event listener to one element (in this case, the <table>) and wait for events to bubble up from its children. The way to do this using the .on() method requires only one change from our code above:
$('table').on('click','td',function() {
$(this).toggleClass('active');
});
All we’ve done is moved the td selector to an argument inside the .on() method. Providing a selector to .on() switches it into delegation mode, and the event is only fired for descendants of the bound element (table) that match the selector (td). With that one simple change, we’ve gone from having to bind one hundred event listeners to just one. You might think that the browser having to do one hundred times less work would be a good thing and you’d be completely right. The difference between the two examples above is staggering.
(Note that if your site is using a version of jQuery earlier than 1.7, you can accomplish the very same thing using the .delegate() method. The syntax of how you write the function differs slightly; if you’ve never used it before, it’s worth checking the API docs for that page to see how it works.)
DOM manipulation
jQuery makes it very easy to manipulate the DOM. It’s trivial to create new nodes, insert them, remove other ones, move things around, and so on. While the code to do this is simple to write, every time the DOM is manipulated, the browser has to repaint and reflow content which can be extremely costly. This is no more evident than in a long loop, whether it be a standard for() loop, while() loop, or jQuery $.each() loop.
In this case, let’s say we’ve just received an array full of image URLs from a database or Ajax call or wherever, and we want to put all of those images in an unordered list. Commonly, you’ll see code like this to pull this off:
var arr = [reallyLongArrayOfImageURLs];
$.each(arr, function(count, item) {
var newImg = '<li><img src="'+item+'"></li>';
$('#imgList').append(newImg);
});
There are a couple of problems with this. For one (which you should have already noticed if you’ve read the earlier part of this article), we’re making the $("#imgList") selection once for each iteration of our loop. The other problem here is that each time the loop iterates, it’s adding a new <li> to the DOM. Each of those insertions is going to be costly, and if our array is quite large then this could lead to a massive slowdown or even the dreaded ‘A script is causing this page to run slowly’ warning.
var arr = [reallyLongArrayOfImageURLs],
tmp = '';
$.each(arr, function(count, item) {
tmp += '<li><img src="'+item+'"></li>';
});
$('#imgList').append(tmp);
All we’ve done here is create a tmp variable that each <li> is added to as it’s created. Once our loop has finished iterating, that tmp variable will contain all of our list items in memory, and can be appended to our <ul> all in one go. Browsers work much faster when working with objects in memory rather than on screen, so this is a much faster, more CPU-cycle-friendly method of building a list.
Wrapping up
These are far from being the only ways to make your jQuery code run better, but they are among the simplest ones to implement. Though each individual change may only make a few milliseconds of difference, it doesn’t take long for those milliseconds to add up. Studies have shown that the human eye can discern delays of as few as 100ms, so simply making a few changes sprinkled throughout your code can very easily have a noticeable effect on how well your website or app performs. Do you have other jQuery optimization tips to share? Leave them in the comments and help make us all better.
Now go forth and make awesome! |

Raising the Bar on Mobile |
One of the primary challenges of designing for mobile devices is that screen real estate is often in limited supply. Through the advocacy of Luke W and others, we’ve drawn comfort from the idea that this constraint ends up benefiting users and designers alike, from obvious advantages like portability and reach, to influencing our content strategy decisions through focus and restraint. But that doesn’t mean we shouldn’t take advantage of every last pixel of that screen we can snag!
As anyone who has designed a website for use on a smartphone can attest, there’s an awful lot of space on mobile screens dedicated to browser functions that would be better off toggled out of view. Unfortunately, the visibility of some of these elements is beyond our control, such as the buttons fixed to the bottom of the viewport in iOS’s Safari and the WebOS browser. However, in many devices, the address bar at the top can be manually hidden, and its absence frees up enough pixel room for a large, impactful heading, a critical piece of navigation, or even just a little more white space to air things out.
So, as my humble contribution to this most festive of web publications, today I’ll dig into the approach I used to hide the address bar in a browser-agnostic fashion for sites like BostonGlobe.com, and the jQuery Mobile framework.
Surveying the land
First, let’s assess the chromes of some popular, current mobile browsers. For example purposes, the following screen-captures feature the homepage of the Boston Globe site, without any address-bar-hiding logic in place.
Note: these captures are just mockups – actual experience on these platforms may vary.
On the left is iOS5’s Safari (running on iPhone), and on the right is Windows Phone 7 (pre-Mango).
BlackBerry 7 (left), and Android 2.3 (right).
WebOS (left), Opera Mini (middle), and Opera Mobile (right).
Some browsers, such the default browsers on WebOS and BlackBerry 5, hide the bar automatically without any developer intervention, but many of them don’t. Of these, we can only manually hide the address bar on iOS Safari and Android (according to Opera Web Opener, Mike Taylor, some discussion is underway for support in Opera Mini and Mobile as well, which would be great!). This is unfortunate, but iOS and Android are incredibly popular, so let’s direct our focus there.
Great API, or greatest API?
As it turns out, iOS and Android not only allow you to hide the address bar, they use the same JavaScript method to do so, too (this shouldn’t be surprising, given that they are both WebKit browsers, but nothing expected happens in mobile). However, the method they use is not exactly intuitive. You might set out looking for a JavaScript API dedicated to this purpose, like, say, window.toolbar.hide(), but alas, to hide the address bar you need to use the window.scrollTo method!
window.scrollTo(0, 0);
The scrollTo method is not new, it’s just this particular use of it that is. For the uninitiated, scrollTo is designed to scroll a document to a particular set of coordinates, assuming the document is large enough to scroll to that spot. The method accepts two arguments: a left coordinate; and a top coordinate. It’s both simple and supported well pretty much everywhere. In iOS and Android, these coordinates are calculated from the top of the browser’s viewport, just below the address bar (interestingly, it seems that some platforms like BlackBerry 6 treat the top of the browser chrome as 0 instead, meaning the page content is closer to 20px from the top).
Anyway, by passing the coordinates 0, 0 to the scrollTo method, the browser will jump to the top of the page and pull the address bar out of view! Of course, if a quick call to scrollTo was all we need to do to hide the address bar in iOS and Android, this article would be pretty short, and nothing new. Unfortunately, the first issue we need to deal with is that this method alone will not usually do the trick: it must be called after the page has finished loading.
The browser gives us a load event for just that purpose, so we’ll wrap our scrollTo method in it and continue on our merry way! We’ll use the standard, addEventListener method to bind the the load event, passing arguments for event name load, and a callback function to execute when the event is triggered.
window.addEventListener("load",function() {
window.scrollTo(0, 0);
});
For the sake of preventing errors in those using browsers that don’t support addEventListener, such as Internet Explorer 8 and under, let’s make sure that method exists before we use it:
if( window.addEventListener ){
window.addEventListener("load",function() {
window.scrollTo(0, 0);
});
}
Now we’re getting somewhere, but we must also call the method after the load event’s default behavior has been applied. For this, we can use the setTimeout method, delaying its execution to after the load event has run its course.
if( window.addEventListener ){
window.addEventListener("load",function() {
setTimeout(function(){
window.scrollTo(0, 0);
}, 0);
});
}
Sweet sugar of Christmas! Hit this demo in iOS and watch that address bar drift up and away!
Not so fast…
We’ve got a little problem: the approach above does work in iOS but, in some cases, it works a little too well. In the process of applying this behavior, we’ve broken one of the primary tenets of responsible web development: don’t break the browser’s default behaviour. This usability rule of thumb is often violated by developers with even the best of intentions, from breaking the browser’s back button through unrecorded Ajax page refreshes, to fancy momentum touch scrolling scripts that can wreak havoc in all but the most sophisticated of devices. In this case, we’ve prevented the browser’s native support of deep-linking to sections of a page (a hash identifier in the URL matching a page element’s id attribute, for example, http://example.com#contact) from working properly, because our script always scrolls to the top.
To avoid this collision, we’ll need to detect whether a deep link, or hash, is present in the URL before applying our logic. We can do this by ensuring that the location.hash property is falsey:
if( !window.location.hash && window.addEventListener ){
window.addEventListener( "load",function() {
setTimeout(function(){
window.scrollTo(0, 0);
}, 0);
});
}
Still works great! And a quick test using a hash-based URL confirms that our script will not execute when a deep anchor is in play. Now iOS is looking sharp, and we’ve added our feature defensively to avoid conflicts.
Now, on to Android…
Wait. You didn’t expect that we could write code for one browser and be finished, right? Of course you didn’t. I mentioned earlier that Android uses the same method for getting rid of the scrollbar, but I left out the fact that the arguments it prefers vary slightly, but significantly, from iOS. Bah!
Differering from the earlier logic from iOS, to remove the address bar on Android’s default browser, you need to pass a Y coordinate of 1 instead of 0. Aside from being just plain odd, this is particularly unfortunate because to any other browser on the planet, 1px is a very real, however small, distance from the top of the page!
window.scrollTo( 0, 1 );
Looks like we’re going to need a fork…
R UA Android?
At this point, some developers might decide to simply not support this feature in Android, and more determined devs might decide that a quick check of the User Agent string would be a reliable way to determine the browser and tweak the scroll value accordingly. Neither of those decisions would be tragic, but in the spirit of cross-browser and future-friendly development, I’ll propose an alternative.
By this point, it should be clear that neither of the implementations above offer a particularly intuitive way to hide an address bar. As such, one might be skeptical that these approaches will stick around very long in their present state in either browser. Perhaps at some point, Android will decide to use 0 like iOS, making our lives a little easier, or maybe some new browser will decide to model their address bar hiding method after one of these implementations. In any case, detecting the User Agent only allows us to apply logic based on the known present, and in the world of mobile, let’s face it, the present is already the past.
Writing a check
In this next step of today’s technique, we’ll apply some logic to quickly determine the behavior model of the browser we’re using, then capitalize on that model – without caring which browser it happens to come from – by applying the appropriate scroll distance.
To do this, we’ll rely on a fortunate side effect of Android’s implementation, which is when you programatically scroll the page to 1 using scrollTo, Android will report that it’s still at 0 because oddly enough, it is! Of course, any other browser in this situation will report a scroll distance of 1. Thus, by scrolling the page to 1, then asking the browser its scroll distance, we can use this artifact of their wacky implementation to our advantage and scroll to the location that makes sense for the browser in play.
Getting the scroll distance
To pull off our test, we’ll need to ask the browser for its current scroll distance. The methods for getting scroll distance are not entirely standardized across popular browsers, so we’ll need to use some cross-browser logic. The following scroll distance function is similar to what you’d find in a library like jQuery. It checks the few common ways of getting scroll distance before eventually falling back to 0 for safety’s sake (that said, I’m unaware of any browsers that won’t return a numeric value from one of the first three properties).
// scrollTop getter
function getScrollTop(){
return scrollTop = window.pageYOffset ||
document.compatMode === "CSS1Compat" && document.documentElement.scrollTop ||
document.body.scrollTop || 0;
}
In order to execute that code above, the body object (referenced here as document.body) will need to be defined already, or we’ll risk an error. To determine that it’s defined, we can run a quick timer to execute code as soon as that object is defined and ready for use.
var bodycheck = setInterval(function(){
if( document.body ){
clearInterval( bodycheck );
//more logic can go here!!
}
}, 15 );
Above, we’ve defined a 15 millisecond interval called bodycheck that checks if document.body is defined and, if so, clears itself of running again. Within that if statement, we can extend our logic further to run other code, such as our check for the scroll distance, defined via the variable scrollTop below:
var scrollTop,
bodycheck = setInterval(function(){
if( document.body ){
clearInterval( bodycheck );
scrollTop = getScrollTop();
}
}, 15 );
With this working, we can immediately scroll to 1, then check the scroll distance when the body is defined. If the distance reports 1, we’re likely in a non-Android browser, so we’ll scroll back to 0 and clean up our mess.
window.scrollTo( 0, 1 );
var scrollTop,
bodycheck = setInterval(function(){
if( document.body ){
clearInterval( bodycheck );
scrollTop = getScrollTop();
window.scrollTo( 0, scrollTop === 1 ? 0 : 1 );
}
}, 15 );
Cashing in
All of the pieces are written now, so all we need to do is combine them with our previous logic for scrolling when the window is loaded, and we’ll have a cross-browser solution of which John Resig would be proud. Here’s our combined code snippet, with some formatting updates rolled in as well:
(function( win ){
var doc = win.document;
// If there’s a hash, or addEventListener is undefined, stop here
if( !location.hash && win.addEventListener ){
//scroll to 1
window.scrollTo( 0, 1 );
var scrollTop = 1,
getScrollTop = function(){
return win.pageYOffset || doc.compatMode = "CSS1Compat" && doc.documentElement.scrollTop || doc.body.scrollTop || 0;
},
//reset to 0 on bodyready, if needed
bodycheck = setInterval(function(){
if( doc.body ){
clearInterval( bodycheck );
scrollTop = getScrollTop();
win.scrollTo( 0, scrollTop = 1 ? 0 : 1 );
}
}, 15 );
win.addEventListener( “load”, function(){
setTimeout(function(){
//reset to hide addr bar at onload
win.scrollTo( 0, scrollTop === 1 ? 0 : 1 );
}, 0);
} );
}
})( this );
View code example
And with that, we’ve got a bunch more room to play with on both iOS and Android.
Break out the eggnog
…because we’re not done yet! In the spirit of making our script act more defensively, there’s still another use case to consider. It was essential that we used the window’s load event to trigger our scripting, but on pages with a lot of content, its use can come at a cost. Often, a user will begin interacting with a page, scrolling down as they read, before the load event has fired. In those situations, our script will jump the user back to the top of the page, resulting in a jarring experience.
To prevent this problem from occurring, we’ll need to ensure that the page has not been scrolled beyond a certain amount. We can add a simple check using our getScrollTop function again, this time ensuring that its value is not greater than 20 pixels or so, accounting for a small tolerance.
if( getScrollTop() < 20 ){
//reset to hide addr bar at onload
window.scrollTo( 0, scrollTop === 1 ? 0 : 1 );
}
And with that, we’re pretty well protected! Here’s a final demo.

Your thoughts?
I hope this article provides you with a browser-agnostic approach to hiding the address bar that you can use in your own projects today. Perhaps alternatively, the complications involved in this approach convinced you that doing this well is more trouble than it’s worth and, depending on the use case, that could be a fair decision. But at the very least, I hope this demonstrates that there’s a lot of work involved in pulling off this small task in only two major platforms, and that there’s a real need for standardization in this area.
Feel free to leave a comment or criticism and I’ll do my best to answer in a timely fashion.
Thanks, everyone!
Some parting notes
I scream, you scream…
At the time of writing, I was not able to test this method on the latest Android 4.0 (Ice Cream Sandwich) build. According to Sencha Touch’s browser scorecard, the browser in 4.0 may have a different way of managing the address bar, so I’ll post in the comments once I get a chance to dig into it further.
Short pages get no love
Today’s technique only works when the page is as tall, or taller than, the device’s available screen height, so that the address bar may be scrolled out of view. On a short page, you might work around this issue by applying a minimum height to the body element ( body { min-height: 460px; } ), but given the variety of screen sizes out there, not to mention changes in orientation, it’s tough to find a value that makes much sense (unless you manipulate it with JavaScript). |

Going Both Ways |
It’s that time of the year again: Santa is getting ready to travel the world. Up until now, girls and boys from all over have sent in letters asking for what they want. I hope that Santa and his elves have—unlike me—learned more than just English.
On the Internet, those girls and boys want to participate in sharing their stories and videos of opening presents and of being with friends and family. Ah, yes, the wonders of user generated content. But more than that, people also want to be able to use sites in the language they know.
While you and I might expect the text to read from left to right, not all languages do. Some go from right to left, such as Arabic and Hebrew. (Some also go from top to bottom, but for now, let’s just worry about those first two directions!)
If we were building a site for girls and boys to send their letters to Santa, we need to consider having the interface in the language and direction that they prefer. On the elves’ side, they may be viewing the site in one direction but reading the user generated content in the other direction. We need to build a site that supports bidirectional (or bidi) text.
Let’s take a look at some things to be aware of when it comes to building bidi interfaces.
Setting the direction of the interface
Right off the bat, we need to tell the browser what direction the text should be going in. To do this, we add the dir attribute to an HTML element and set it to either LTR (for left to right) or RTL (for right to left).
<body dir="rtl">
You can add the dir attribute to any element and it will set or change the direction for the content within that element.
<body dir="ltr">
Here is English Content.
<div dir="rtl">الموضوع</div>
</body>
You can also set the direction via CSS.
.rtl {
direction: rtl;
}
It’s generally recommended that you don’t use CSS to set the direction of the text. Text direction is an important part of the content that should be retained even in environments where the CSS may not be available or fails to load.
How things change with the direction attribute
Just adding the dir attribute tells the browser to render the content within it differently.
The text aligns to the right of the page and, interestingly, punctuation appears at the left of the sentence. (We’ll get to that in a little bit.)
Scrollbars in most browsers will appear on the left instead of the right. Webkit is the notable exception here which always shows the scrollbar on the right, no matter what the text direction is. Avoid having a design that has an expectation that the scrollbar will be in a specific place (and a specific size).
Changing the order of text mid-way
As we saw in that previous example, the punctuation appeared at the beginning of the sentence instead of the end, even though the text was English. At Yahoo!, we have an interesting dilemma where the company name has punctuation in it. Therefore, when the name appears in the middle of (for example) Arabic text, the exclamation mark appears at the beginning of the word instead of the end.
There are two ways in which this problem can be solved:
1. Use HTML around the left-to-right content, or
To solve the problem of the Yahoo! name in the midst of Arabic text, we can wrap a span around it and change the direction on that element.
2. Use a text direction mark in the content.
Unicode has two marks, U+200E and U+200F, that tell the browser that the text is in a particular direction. Placing this right after the punctuation will correct the placement.
Using the HTML entity:
Yahoo!
Tables
Thankfully, the cells of a data table also get reordered from right to left. Equally as nice, if you’re using display:table, the content will still get reordered.
CSS
So far, we’ve seen that the dir attribute does a pretty decent job of getting content flowing in the direction that we need it. Unfortunately, there are huge swaths of design that is handled by CSS that the handy dir attribute has zero effect over.
Many properties, like float or absolute positioning with left and right values, are unaffected and must be handled manually. Elements that were floated left must now by floated right. Left margins and paddings must now move to the right and the right margins and paddings must now move to the left.
Since the browser won’t handle this for us, we have a couple approaches that we can use:
CSS Only
We can take advantage of the attribute selector to target CSS to apply in one direction or another.
[dir=ltr] .module {
float: left;
margin: 0 0 0 20px;
}
[dir=rtl] .module {
float: right;
margin: 0 20px 0 0;
}
As you can see from this example, both of the properties have been modified for the flipped interface. If your interface is rather complicated, you will have to create a lot of duplicate rules to have the site looking good in both directions while serving up a single stylesheet.
CSSJanus
Google has a tool called CSSJanus. It’s a Python script that runs over the LTR versions of your CSS files and generates RTL versions. For the RTL version of the site, just serve up those CSS files instead of the LTR versions.
The script looks for keywords and value combinations and automatically swaps them so you don’t have to.
At Yahoo!, CSSJanus was a huge help in speeding up our development of a bidi interface. We’ve also made a number of improvements to the script to better handle border radius, background positioning, and gradients. We will be pushing those changes back into the CSSJanus project.
Background Images
Background images, especially for things like CSS sprites, also raise an interesting dilemma. Background images are positioned relative to the left of the element. In a flipped interface, however, we need to position it relative to the right. An icon that would be to the left of some text will now need to appear on the right.
If the x position of the background is percentage-based, then it’s fairly easy to swap the values. 0 becomes 100%, 10% becomes 90% and so on. If the x position is pixel-based, then we’re in a bit of a pickle. There’s no way to say that the image should be a certain number of pixels from the right.
Therefore, you’ll need to ensure that any background image that needs to be swapped should be percentage-based. (99.9% of the the time, the background position will need to be 0 so that it can be changed to 100% for RTL.)
If you’re taking an existing implementation, background positioning will likely be the biggest hurdle you’ll have to overcome in swapping your interface around. If you make sure your x position is always percentage-based from the beginning, you’ll have a much smoother process ahead of you!
Flipping Images
This is a more subtle point and one where you’ll really want an expert with the region to weigh in on. In RTL interfaces, users may expect certain icons to also be flipped. Pencil icons that skew to the right in LTR interfaces might need to be swapped to skew to the left, instead. Chat bubbles that come from the left will need to come from the right.
The easiest way to handle this is to create new images. Name the LTR versions with -ltr in the name and name the RTL versions with -rtl in the name. CSSJanus will automatically rename all file references from -ltr to -rtl.
The Future
Thankfully, those within the W3C recognize that CSS should be more agnostic. As a result, they’ve begun introducing new properties that allow the browser to manage the swapping from left to right for us.
The CSS3 specification for backgrounds allows for the background-position to be relative to other corners other than the top left by specifying keywords before each position.
This will position the background 5px from the bottom right of the element.
background-position: right 5px bottom 5px;
Opera 11.60 is currently the only browser that supports this syntax.
For margin and padding, we have margin-start and margin-end. In LTR interfaces, margin-start would be the same as margin-left and in RTL interfaces, margin-start would be the same as margin-right.
Firefox and Webkit support these but with vendor prefixes right now:
-webkit-margin-start: 20px;
-moz-margin-start: 20px;
In the CSS3 Images working draft specification, there’s an image() property that allows us to specify image fallbacks and whether those fallbacks are for LTR or RTL interfaces.
background: image('sprite.png' ltr, 'sprite-rtl.png' rtl);
Unfortunately, no browser supports this yet but it’s nice to be able to dream of how much easier this will be in the future!
Ho Ho Ho
Hopefully, after all of this, you’re full of cheer knowing that you’re well on your way to creating interfaces that can go both ways! |

Design the Invisible to Tell Better Stories on the Web |
For design to be meaningful we need to tell stories. We need to design the invisible, the cues, the messages and the extra detail hidden beneath the aesthetics. It’s all about the story.
From verbal exchanges around the campfire to books, the web and everything in between, storytelling allows us to share, organize and process information more efficiently. It helps us understand our surroundings and make emotional connections to people, places and experiences.
Web design lends itself perfectly to the conventions of storytelling, a universal process. However, the stories vary because they’re defined by culture, society, politics and religion. All of which need considering if you are to design stories that are relevant to your target audience.
The benefits of approaching design with storytelling in mind from the very start of the project is that we are creating considered design that allows users to quickly gather meaning from the website. They do this by reading between the lines and drawing on the wealth of knowledge they have acquired about the associations between colours, typyefaces and signs.
With so much recognition and analysis happening subconsciously you have to consider how design communicates on this level. This invisible layer has a significant impact on what you say, how you say it and who you say it to.
How can we design something that’s invisible?
By researching and making conscious decisions about exactly what you are communicating, you can make the invisible visible. As is often quoted, good design is like air, you only notice it when it’s bad. So by designing the invisible the aim is to design stories that the audience receive subliminally, so that they go somewhat unnoticed, like good air.
Storytelling strands
To share these stories through design, you can break it down into several strands. Each strand tells a story on its own, but when combined they may start to tell a different story altogether. These strands are colour, typefaces, branding, tone of voice and symbols. All are literal and visible but the invisible element is the meaning behind them – meaning that you can extract and share. In this article I want to focus on colour, typefaces and tone of voice and on how combining story strands can change the meaning.
Colour
Let’s start with colour. Red represents emotions such as love but can also signify war. Green is commonly used for all things environmental and purple is a colour that connotes wealth and royalty. These associations between colour and emotion or value have been learned over time and are continually reinforced through media and culture.
With this knowledge come expectations from your users. For example, they will expect Valentine’s Day sites to be red and kids’ sites to be bright and colourful. This is true in the same way audiences have expectations of certain genres of film or music. These conventions help savvy audiences decode texts and read between the lines or, rather, to draw meaning from the invisible. It’s practically an innate skill. This is why you need to design the invisible: because users will quickly deduce meaning from your site and fill in the story’s gaps, it’s important to give them as much of that story to begin with. A story relevant to their culture.
Of all the ways you can tell stories through web design, colour is the most fascinating and important. Not only does it evoke emotions in users but its meaning varies significantly between cultures. In the west, for example, white is a colour associated with weddings, and black is the colour of mourning. This is signified by the traditions of brides wearing white and those in mourning wearing black. In other cultures the meanings are reversed, as black is a colour that represents good luck and white is a colour that signifies mourning. If you assume the same values are true in all cultures then you risk offending the very people you are targeting.
When colours combine, the story being told can change. If you design using red, white and blue then it’s going to be difficult to shake off patriotic connotations because this colour combination is so ingrained as being American or British or French thanks largely to their flags. This extends to politics too. Each party has its own representative colour. In the UK, the Conservatives are blue and Labour is red so it would be inappropriate storytelling to design a Labour-related website in blue as there would be a conflict between the content and the design, a conflict that would result in a poor user experience.
Conflicts become more of an issue when you start to combine story strands. I once saw a No VAT advert use the symbol on the left:
There’s a complete conflict in storytelling here between the sign and its colour. The prohibition sign was used over the word VAT to mean no VAT; that makes sense. But this is a symbol that is used to communicate to people that something is being prohibited or prevented, it mustn’t continue. So to use green contradicts the message of the sign itself; green is used as a colour to say yes, go, proceed, enter. The same would be true if we had a tick in red and a cross in green. Bad design here means the story is flawed and the user experience is compromised.
Typefaces
Typefaces also tell stories. They are so much more than the words that are written with them because they connote different values. Here are a few:
Serif fonts are more formal and are associated with tradition, sophistication and high-end values. Sans serif fonts, on the other hand, are synonymous with modernity, informality and friendliness. These perceptions are again reinforced through more traditional media such as newspaper mastheads, where the serious news-focused broadsheets have serif titles, and the showbiz and gossip-led tabloids have sans serif titles. This translates to the web as well. With these associations already familiar to users, they may see copy and focus on the words, but if the way that copy is displayed jars with the context then we are back to having conflicting stories like the No VAT sign earlier.
Let’s take official institutions, for example. The White House, the monarchy, 10 Downing Street and other government departments are formal, traditional and important organisations. If the copy on their websites were written in a typeface like Cooper Black, it would erase any authority and respect that they were due. They need people to take them seriously and trust them, and part of the way to do this is to have a typeface that represents those values.
It works both ways though. If Innocent, Threadless or other fun companies used traditional typefaces, they wouldn’t be accurate reflections of their core values, brand and personality. They are better positioned to use friendly, informal and modern typefaces. But still never Comic Sans.
Tone of voice
Closely tied to this is tone of voice, my absolute bugbear on the web. Tone of voice isn’t what is said but, rather, how it is said. When we interact with others in person we don’t just listen to the words they say, but we also draw meaning from their body language, and pitch and tone of voice. Just because the web removes that face-to-face interaction with your audience it doesn’t mean you can’t have a tone of voice.
Innocent pioneered the informal chatty tone of voice that so many others have since emulated, but unless it is representative of your company, then it’s not appropriate. It works for Innocent because the tone of voice is consistent across all the company’s materials, both online and offline. Ben and Jerry’s takes the same approach, as does Threadless, but maybe you need a more formal or corporate tone of voice. It really depends on what your business or service is and who it is for, and that is why I think LoveFilm has it all wrong.
LoveFilm offers a film and game rental service, something fun for people in their downtime. While they aren’t particularly stuffy, neither is their tone of voice very friendly or informal, which is what I would expect from a service like theirs. The reason they have it wrong is in the language they use and the way their sentences are constructed.
This is the first time we’ve discussed language because, on the whole, designing the invisible isn’t concerned with language at all. But that doesn’t mean that these strands can’t still elicit an emotional response in users. Jon Tan quoted Dr Mazviita Chirimuuta in his New Adventures in Web Design talk in January 2011:
Although there is no absolute separation between language and emotion, there will still be countless instances where you have emotional response without verbal input or linguistic cognition. In general language is not necessary for emotion.
This is even more pertinent when the emotions evoked are connected to people’s culture, surroundings and way of life. It makes design personal, something that audiences can connect with at more than just face value but, rather, on a subliminal or, indeed, invisible level.
It also means that when you are asked the inevitable question of why – why is blue the dominant colour? why have you used that typeface? why don’t we sound like Innocent? – you will have a rationale behind each design decision that can explain what story you are telling, how you discovered the story and how it is targeted at the core audience.
Research
This is where research plays a vital role in the project cycle. If you don’t know and understand your audience then you don’t know what story to design. Every project lends itself to some level of research, but how in-depth and what methods are most appropriate will be dictated by project requirements and budget restrictions – but do your research.
Even if you think you know your audience, it doesn’t hurt to research and reaffirm that because cultures and society do change, albeit slowly, but they can change. So ask questions at the start of the project during the research phase:
What do different colours mean for your audience’s culture?
Do the typeface and tone of voice appeal to the demographic?
Does the brand identity represent the values and personality of your service?
Are there any social, political or religious significances associated with your audience that you need to take into consideration so you don’t offend them?
Ask questions, understand your audience, design your story based on these insights, and create better user experiences in context that have good, solid storytelling at their heart.

Conditional Loading for Responsive Designs |
On the eighteenth day of last year’s 24 ways, Paul Hammond wrote a great article called Speed Up Your Site with Delayed Content. He outlined a technique for loading some content — like profile avatars — after the initial page load. This gives you a nice performance boost.
There’s another situation where this kind of delayed loading could be really handy: mobile-first responsive design.
Responsive design combines three techniques:
a fluid grid
flexible images
media queries
At first, responsive design was applied to existing desktop-centric websites to allow the layout to adapt to smaller screen sizes. But more recently it has been combined with another innovative approach called mobile first.
Rather then starting with the big, bloated desktop site and then scaling down for smaller devices, it makes more sense to start with the constraints of the small screen and then scale up for larger viewports. Using this approach, your layout grid, your large images and your media queries are applied on top of the pre-existing small-screen design. It’s taking progressive enhancement to the next level.
One of the great advantages of the mobile-first approach is that it forces you to really focus on the core content of your page. It might be more accurate to think of this as a content-first approach. You don’t have the luxury of sidebars or multiple columns to fill up with content that’s just nice to have rather than essential.
But what happens when you apply your media queries for larger viewports and you do have sidebars and multiple columns? Well, you can load in that nice-to-have content using the same kind of Ajax functionality that Paul described in his article last year. The difference is that you first run a quick test to see if the viewport is wide enough to accommodate the subsidiary content. This is conditional delayed loading.
Consider this situation: I’ve published an article about cats and I’d like to include relevant cat-related news items in the sidebar …but only if there’s enough room on the screen for a sidebar.
I’m going to use Google’s News API to return the search results. This is the ideal time to use delayed loading: I don’t want a third-party service slowing down the rendering of my page so I’m going to fire off the request after my document has loaded.
Here’s an example of the kind of Ajax function that I would write:
var searchNews = function(searchterm) {
var elem = document.createElement('script');
elem.src = 'http://ajax.googleapis.com/ajax/services/search/news?v=1.0&q='+searchterm+'&callback=displayNews';
document.getElementsByTagName('head')[0].appendChild(elem);
};
I’ve provided a callback function called displayNews that takes the JSON result of that Ajax request and adds it an element on the page with the ID newsresults:
var displayNews = function(news) {
var html = '',
items = news.responseData.results,
total = items.length;
if (total>0) {
for (var i=0; i<total; i++) {
var item = items[i];
html+= '<article>';
html+= '<a href="'+item.unescapedUrl+'">';
html+= '<h3>'+item.titleNoFormatting+'</h3>';
html+= '</a>';
html+= '<p>';
html+= item.content;
html+= '</p>';
html+= '</article>';
}
document.getElementById('newsresults').innerHTML = html;
}
};
Now, I can call that function at the bottom of my document:
<script>
searchNews('cats');
</script>
If I only want to run that search when there’s room for a sidebar, I can wrap it in an if statement:
<script>
if (document.documentElement.clientWidth > 640) {
searchNews('cats');
}
</script>
If the browser is wider than 640 pixels, that will fire off a search for news stories about cats and put the results into the newsresults element in my markup:
<div id="newsresults">
<!-- search results go here -->
</div>
This works pretty well but I’m making an assumption that people with small-screen devices wouldn’t be interested in seeing that nice-to-have content. You know what they say about assumptions: they make an ass out of you and umptions. I should really try to give everyone at least the option to get to that extra content:
<div id="newsresults">
<a href="http://www.google.com/search?q=cats&tbm=nws">Search Google News</a>
</div>
See the result
Visitors with small-screen devices will see that link to the search results; visitors with larger screens will get the search results directly.
I’ve been concentrating on HTML and JavaScript, but this technique has consequences for content strategy and information architecture. Instead of thinking about possible page content in a binary way as either ‘on the page’ or ‘not on the page’, conditional loading introduces a third ‘it’s complicated’ option.
This was just a simple example but I hope it illustrates that conditional loading could become an important part of the content-first responsive design approach. |

Nine Things I've Learned |
I’ve been a professional graphic designer for fourteen years and for just under four of those a professional web designer. Like most designers I’ve learned a lot in my time, both from a design point of view and in business as freelance designer. A few of the things I’ve learned stick out in my mind, so I thought I’d share them with you. They’re pretty random and in no particular order.
1. Becoming the designer you want to be
When I started out as a young graphic designer, I wanted to design posters and record sleeves, pretty much like every other young graphic designer. The problem is that the reality of the world means that when you get your first job you’re designing the back of a paracetamol packet or something equally weird. I recently saw a tweet that went something like this: “You’ll never become the designer you always dreamt of being by doing the work you never wanted to do”. This is so true; to become the designer you want to be, you need to be designing the things you’re passionate about designing. This probably this means working in the evenings and weekends for little or no money, but it’s time well spent. Doing this will build up your portfolio with the work that really shows what you can do! Soon, someone will ask you to design something based on having seen this work. From this point, you’re carving your own path in the direction of becoming the designer you always wanted to be.
2. Compete on your own terms
As well as all being friends, we are also competitors. In order to win new work we need a selling point, preferably a unique selling point. Web design is a combination of design disciplines – user experience design, user interface Design, visual design, development, and so on. Some companies will sell themselves as UX specialists, which is fine, but everyone who designs a website from scratch does some sort of UX, so it’s not really a unique selling point. Of course, some people do it better than others.
One area of web design that clients have a strong opinion on, and will judge you by, is visual design. It’s an area in which it’s definitely possible to have a unique selling point. Designing the visual aesthetic for a website is a combination of logical decision making and a certain amount of personal style. If you can create a unique visual style to your work, it can become a selling point that’s unique to you.
3. How much to charge and staying motivated
When you’re a freelance designer one of the hardest things to do is put a price on your work and skills. Finding the right amount to charge is a fine balance between supplying value to your customer and also charging enough to stay motivated to do a great job. It’s always tempting to offer a low price to win work, but it’s often not the best approach: not just for yourself but for the client as well.
A client once asked me if I could reduce my fee by £1,000 and still be motivated enough to do a good job. In this case the answer was yes, but it was the question that resonated with me. I realized I could use this as a gauge to help me price projects. Before I send out a quote I now always ask myself the question “Is the amount I’ve quoted enough to make me feel motivated to do my best on this project?” I never send out a quote unless the answer is yes. In my mind there’s no point in doing any project half-heartedly, as every project is an opportunity to build your reputation and expand your portfolio to show potential clients what you can do. Offering a client a good price but not being prepared to put everything you have into it, isn’t value for money.
4. Supplying the right design
When I started out as a graphic designer it seemed to be the done thing to supply clients with a ton of options for their logo or brochure designs. In a talk given by Dan Rubin, he mentioned that this was a legacy of agencies competing with each other in a bid to create the illusion of offering more value for money. Over the years, I’ve realized that offering more than one solution makes no sense. The reason a client comes to you as a designer is because you’re the person than can get it right. If I were to supply three options, I’d be knowingly offering my client at least two options that I didn’t think worked.
To this day I still get asked how many homepage design options I’ll supply for the quoted amount. The answer is one. Of course, I’m more than happy to iterate upon the design to fine-tune it and, on the odd occasion, I do revisit a design concept if I just didn’t nail the design first time around. Your time is much better spent refining the right design option than rushing out three substandard designs in the same amount of time.
5. Colour is key
There are many contributing factors that go into making a good visual design, but one of the simplest ways to do this is through the use of colour. The colour palette used in a design can have such a profound effect on a visual design that it almost feels like you’re cheating. It’s easy to add more and more subtle shades of colour to add a sense of sophistication and complexity to a design, but it dilutes the overall visual impact. When I design, I almost have a rule that only allows me to use a very limited colour palette. I don’t always stick to it, but it’s always in mind and something I’m constantly reviewing through my design process.
6. Creative thinking is central to good or boundary-pushing web design
When we think of creativity in web design we often link this to the visual design, as there is an obvious opportunity to be creative in this area if the brief allows it. Something that I’ve learnt in my time as a web designer is that there’s a massive need for creative thinking in the more technical aspects of web design. The tools we use for building websites are there to be manipulated and used in creative ways to design exciting and engaging user experiences. Great developers are constantly using their creativity to push the boundaries of what can be done with CSS, jQuery and JavaScript.
Being creative and creative thinking are things we should embrace as an industry and they are qualities that can be found in anyone, whether they be a visual designer or Rails developer.
7. Creative block: don’t be afraid to get things wrong
Creative block can be a killer when designing. It’s often applied to visual design, which is more subjective. I suffer from creative block on a regular basis. It’s hugely frustrating and can screw up your schedule. Having thought about what creative block actually is, I’ve come to the conclusion that it’s actually more of a lack of direction than a lack of ideas. You have ideas and solutions in mind but don’t feel committed to any of them. You’re scared that whatever direction you take, it’ll turn out to be wrong. I’ve found that the best remedy for this is to work through this barrier. It’s a bit like designing with a blindfold on – you don’t really know where you’re going. If you stick to your guns and keep pressing forward I find that, nine times out of ten, this process leads to a solution. As the page begins to fill, the direction you’re looking for slowly begins to take shape.
8. You get better at designing by designing
I often get emails asking me what books someone can read to help them become a better designer. There are a lot of good books on subjects like HTML5, CSS, responsive web design and the like, that will really help improve anyone’s web design skills. But, when it comes to visual design, the best way to get better is to design as much as possible. You can’t follow instructions for these things because design isn’t following instructions. A large part of web design is definitely applying a set of widely held conventions, but there’s another part to it that is invention and the only way to get better at this is to do it as much as possible.
9. Self-belief is overrated
Throughout our lives we’re told to have self-belief. Self-belief and confidence in what we do, whatever that may be. The problem is that some people find it easier than others to believe in themselves. I’ve spent years trying to convince myself to believe in what I do but have always found it difficult to have complete confidence in my design skills. Self-doubt always creeps in.
I’ve realized that it’s ok to doubt myself and I think it might even be a good thing! I’ve realized that it’s my self-doubt that propels me forward and makes me work harder to achieve the best results. The reason I’m sharing this is because I know I’m not the only designer that feels this way. You can spend a lot of time fighting self-doubt only to discover that it’s your body’s natural mechanism to help you do the best job possible. |

Front-end Style Guides |
We all know that feeling: some time after we launch a site, new designers and developers come in and make adjustments. They add styles that don’t fit with the content, use typefaces that make us cringe, or chuck in bloated code. But if we didn’t leave behind any documentation, we can’t really blame them for messing up our hard work.
To counter this problem, graphic designers are often commissioned to produce style guides as part of a rebranding project. A style guide provides details such as how much white space should surround a logo, which typefaces and colours a brand uses, along with when and where it is appropriate to use them.
Design guidelines
Some design guidelines focus on visual branding and identity. The UK National Health Service (NHS) refer to theirs as “brand guidelines”. They help any designer create something such as a trustworthy leaflet for an NHS doctor’s surgery. Similarly, Transport for London’s “design standards” ensure the correct logos and typefaces are used in communications, and that they comply with the Disability Discrimination Act.
Some guidelines go further, encompassing a whole experience, from the visual branding to the messaging, and the icon sets used. The BBC calls its guidelines a “Global Experience Language” or GEL. It’s essential for maintaining coherence across multiple sites under the same BBC brand.
The BBC’s Global Experience Language.
Design guidelines may be brief and loose to promote creativity, like Mozilla’s “brand toolkit”, or be precise and run to many pages to encourage greater conformity, such as Apple’s “Human Interface Guidelines”.
Whatever name or form they’re given, documenting reusable styles is invaluable when maintaining a brand identity over time, particularly when more than one person (who may not be a designer) is producing material.
Code standards documents
We can make a similar argument for code. For example, in open source projects, where hundreds of developers are submitting code, it makes sense to set some standards. Drupal and Wordpress have written standards that make editing code less confusing for users, and more maintainable for contributors.
Each community has nuances: Drupal requests that developers indent with two spaces, while Wordpress stipulates a tab. Whatever the rules, good code standards documents also explain why they make their recommendations.
The front-end developer’s style guide
Design style guides and code standards documents have been a successful way of ensuring brand and code consistency, but in between the code and the design examples, web-based style guides are emerging. These are maintained by front-end developers, and are more dynamic than visual design guidelines, documenting every component and its code on the site in one place.
Here are a few examples I’ve seen in the wild:
Natalie Downe’s pattern portfolio
Natalie created the pattern portfolio system while working at Clearleft. The phrase describes a single HTML page containing all the site’s components and styles that can act as a deliverable.
Pattern portfolio by Natalie Downe for St Paul’s School, kept up to date when new components are added. The entire page is about four times the length shown.
Each different item within a pattern portfolio is a building block or module. The components are decoupled from the layout, and linearized so they can slot into anywhere on a page.
The pattern portfolio expresses every component and layout structure in the smallest number of documents. It sets out how the markup and CSS should be, and is used to illustrate the project’s shared vocabulary.
Natalie Downe
By developing a system, rather than individual pages, the result is flexible when the client wants to add more pages later on.
Paul Lloyd’s style guide
Paul Lloyd has written an extremely comprehensive style guide for his site. Not only does it feature every plausible element, but it also explains in detail when it’s appropriate to use each one.
Paul’s style guide is also great educational material for people learning to write code.
Oli Studholme’s style guide
Even though Oli’s style guide is specific to his site, he’s written it as though it’s for someone else. It’s exhaustive and gives justifications for all his decisions. In some places, he links to browser bug tickets and makes recommendations for cross-browser compatibility.
Oli has released his style guide under a Creative Commons Attribution Share-alike license, and encourages others to create their own versions.
Jeremy Keith’s pattern primer
Front-end style guides may have comments written in the code, annotations that appear on the page, or they may list components alongside their code, like Jeremy’s pattern primer.
You can watch or fork Jeremy’s pattern primer on Github.
Linearizing components like this resembles a kind of mobile first approach to development, which Jeremy talks about on the 5by5 podcast: The Web Ahead 3.
The benefits of maintaining a front-end style guide
If you still need convincing that producing documentation like this for every project is worth the effort, here are a few nice side-effects to working this way:
Easier to test
A unified style guide makes it easier to spot where your design breaks. It’s simple to check how components adapt to different screen widths, test for browser bugs and develop print style sheets when everything is on the same page. When I worked with Natalie, she’d resize the browser window and bump the text size up and down during development to see if anything would break.
Better workflow
The approach also forces you to think how something works in relation to the whole site, rather than just a specific page, making it easier to add more pages later on. Starting development by creating a style guide makes a lot more sense than developing on a page-by-page basis.
Shared vocabulary
Natalie’s pattern portfolio in particular creates a shared vocabulary of names for components (teaser, global navigation, carousel…), so a team can refer to different regions of the site and have a shared understanding of its meaning.
Useful reference
A combined style guide also helps designers and writers to see the elements that will be incorporated in the site and, therefore, which need to be designed or populated. A boilerplate list of components for every project can act as a reminder of things that may get missed in the design, such as button states or error messages.
Creating your front-end style guide
As you’ve seen, there are plenty of variations on the web style guide. Which method is best depends on your project and workflow. Let’s say you want to show your content team how blockquotes and asides look, when it’s appropriate to use them, and how to create them within the CMS. In this case, a combination of Jeremy’s pattern primer and Paul’s descriptive style guide – with the styled component alongside a code snippet and a description of when to use it – may be ideal.
Start work on your style guide as soon as you can, preferably during the design stage:
Simply presenting flat image comps is by no means enough - it’s only the start… As layouts become more adaptable, flexible and context-specific, so individual components will become the focus of our design. It is therefore essential to get the foundational aspects of our designs right, and style guides allow us to do that.
Paul Lloyd on Style guides for the Web
Print out the designs and label the unique elements and components you’ll need to add to your style guide. Make a note of the purpose of each component. While you’re doing this, identify the main colours used for things like links, headings and buttons.
I draw over the print-outs on to tracing paper so I can make more annotations. Here, I’ve started annotating the widths from the designer’s mockup so I can translate these into percentages.
Start developing your style guide with base styles that target core elements: headings, links, tables, blockquotes, ordered lists, unordered lists and forms. For these elements, you could maintain a standard document to reuse for every project.
Next, add the components that override the base styles, like search boxes, breadcrumbs, feedback messages and blog comments. Include interaction styles, such as hover, focus and visited state on links, and hover, focus and active states on buttons.
Now start adding layout and begin slotting the components into place. You may want to present each layout as a separate document, or you could have them all on the same page stacked beneath one another.
Document code practices
Code can look messy when people use different conventions, so note down a standard approach alongside your style guide. For example, Paul Stanton has documented how he writes CSS.
The gift wrapping
Presenting this documentation to your client may be a little overwhelming so, to be really helpful, create a simple page that links together all your files and explains what each of them do.
This is an example of a contents page that Clearleft produce for their clients. They’ve added date stamps, subversion revision numbers and written notes for each file.
Encourage participation
There’s always a risk that the person you’re writing the style guide for will ignore it completely, so make your documentation as user-friendly as possible. Justify why you do things a certain way to make it more approachable and encourage similar behaviour.
As always, good communication helps. Working with the designer to put together this document will improve the site. It’s often not practical for designers to provide a style for everything, so drafting a web style guide and asking for feedback gives designers a chance to make sure any default styles fit in.
If you work in a team with other developers, documenting your code and development decisions will not only be useful as a deliverable, but will also force you to think about why you do things a certain way.
Future-friendly
The roles of designer and developer are increasingly blurred, yet all too often we work in isolation. Working side-by-side with designers on web style guides can vastly improve the quality of our work, and the collaborative approach can spark discussions like “how would this work on a smaller screen?”
Sometimes we can be so focused on getting the site ready and live, that we lose sight of what happens after it’s launched, and how it’s going to be maintained. A simple web style guide can make all the difference.
If you make your own style guide, I’d love to add it to my stash of examples so please share a link to it in the comments. |

CSS3 Patterns, Explained |
Many of you have probably seen my CSS3 patterns gallery. It became very popular throughout the year and it showed many web developers how powerful CSS3 gradients really are. But how many really understand how these patterns are created? The biggest benefit of CSS-generated backgrounds is that they can be modified directly within the style sheet. This benefit is void if we are just copying and pasting CSS code we don’t understand. We may as well use a data URI instead.
Important note
In all the examples that follow, I’ll be using gradients without a vendor prefix, for readability and brevity. However, you should keep in mind that in reality you need to use all the vendor prefixes (-moz-, -ms-, -o-, -webkit-) as no browser currently implements them without a prefix. Alternatively, you could use -prefix-free and have the current vendor prefix prepended at runtime, only when needed.
The syntax described here is the one that browsers currently implement. The specification has since changed, but no browser implements the changes yet. If you are interested in what is coming, I suggest you take a look at the dev version of the spec.
If you are not yet familiar with CSS gradients, you can read these excellent tutorials by John Allsopp and return here later, as in the rest of the article I assume you already know the CSS gradient basics:
CSS3 Linear Gradients
CSS3 Radial Gradients
The main idea
I’m sure most of you can imagine the background this code generates:
background: linear-gradient(left, white 20%, #8b0 80%);
It’s a simple gradient from one color to another that looks like this:
See this example live
As you probably know, in this case the first 20% of the container’s width is solid white and the last 20% is solid green. The other 60% is a smooth gradient between these colors. Let’s try moving these color stops closer to each other:
background: linear-gradient(left, white 30%, #8b0 70%);
See this example live
background: linear-gradient(left, white 40%, #8b0 60%);
See this example live
background: linear-gradient(left, white 50%, #8b0 50%);
See this example live
Notice how the gradient keeps shrinking and the solid color areas expanding, until there is no gradient any more in the last example. We can even adjust the position of these two color stops to control where each color abruptly changes into another:
background: linear-gradient(left, white 30%, #8b0 30%);
See this example live
background: linear-gradient(left, white 90%, #8b0 90%);
See this example live
What you need to take away from these examples is that when two color stops are at the same position, there is no gradient, only solid colors. Even without going any further, this trick is useful for a number of different use cases like faux columns or the effect I wanted to achieve in my homepage or the -prefix-free page where the background is only shown on one side and hidden on the other:
Combining with background-size
We can do wonders, however, if we combine this with the CSS3 background-size property:
background: linear-gradient(left, white 50%, #8b0 50%);
background-size: 100px 100px;
See this example live
And there it is. We just created the simplest of patterns: (vertical) stripes. We can remove the first parameter (left) or replace it with top and we’ll get horizontal stripes. However, let’s face it: Horizontal and vertical stripes are kinda boring. Most stripey backgrounds we see on the web are diagonal. So, let’s try doing that.
Our first attempt would be to change the angle of the gradient to something like 45deg. However, this results in an ugly pattern like this:
See this example live
Before reading on, think for a second: why didn’t this produce the desired result? Can you figure it out?
The reason is that the gradient angle rotates the gradient inside each tile, not the tiled background as a whole. However, didn’t we have the same problem the first time we tried to create diagonal stripes with an image? And then we learned that every stripe has to be included twice, like so:
So, let’s try to create that effect with CSS gradients. It’s essentially what we tried before, but with more color stops:
background: linear-gradient(45deg, white 25%,
#8b0 25%, #8b0 50%,
white 50%, white 75%,
#8b0 75%);
background-size:100px 100px;
See this example live
And there we have our stripes! An easy way to remember the order of the percentages and colors it is that you always have two of the same in succession, except the first and last color.
Note: Firefox for Mac also needs an additional 100% color stop at the end of any pattern with more than two stops, like so: ..., white 75%, #8b0 75%, #8b0). The bug was reported in February 2011 and you can vote for it and track its progress at Bugzilla.
Unfortunately, this is essentially a hack and we will realize that if we try to change the gradient angle to 60deg:
See this example live
Not that maintainable after all, eh? Luckily, CSS3 offers us another way of declaring such backgrounds, which not only helps this case but also results in much more concise code:
background: repeating-linear-gradient(60deg, white, white 35px, #8b0 35px, #8b0 70px);
See this example live
In this case, however, the size has to be declared in the color stop positions and not through background-size, since the gradient is supposed to cover the entire container. You might notice that the declared size is different from the one specified the previous way. This is because the size of the stripes is measured differently: in the first example we specify the dimensions of the tile itself; in the second, the width of the stripes (35px), which is measured diagonally.
Multiple backgrounds
Using only one gradient you can create stripes and that’s about it. There are a few more patterns you can create with just one gradient (linear or radial) but they are more or less boring and ugly. Almost every pattern in my gallery contains a number of different backgrounds. For example, let’s create a polka dot pattern:
background: radial-gradient(circle, white 10%, transparent 10%),
radial-gradient(circle, white 10%, black 10%) 50px 50px;
background-size:100px 100px;
See this example live
Notice that the two gradients are almost the same image, but positioned differently to create the polka dot effect. The only difference between them is that the first (topmost) gradient has transparent instead of black. If it didn’t have transparent regions, it would effectively be the same as having a single gradient, as the topmost gradient would obscure everything beneath it.
There is an issue with this background. Can you spot it?
This background will be fine for browsers that support CSS gradients but, for browsers that don’t, it will be transparent as the whole declaration is ignored. We have two ways to provide a fallback, each for different use cases. We have to either declare another background before the gradient, like so:
background: black;
background: radial-gradient(circle, white 10%, transparent 10%),
radial-gradient(circle, white 10%, black 10%) 50px 50px;
background-size:100px 100px;
or declare each background property separately:
background-color: black;
background-image: radial-gradient(circle, white 10%, transparent 10%),
radial-gradient(circle, white 10%, transparent 10%);
background-size:100px 100px;
background-position: 0 0, 50px 50px;
The vigilant among you will have noticed another change we made to our code in the last example: we altered the second gradient to have transparent regions as well. This way background-color serves a dual purpose: it sets both the fallback color and the background color of the polka dot pattern, so that we can change it with just one edit. Always strive to make code that can be modified with the least number of edits. You might think that it will never be changed in that way but, almost always, given enough time, you’ll be proved wrong.
We can apply the exact same technique with linear gradients, in order to create checkerboard patterns out of right triangles:
background-color: white;
background-image: linear-gradient(45deg, black 25%, transparent 25%, transparent 75%, black 75%),
linear-gradient(45deg, black 25%, transparent 25%, transparent 75%, black 75%);
background-size:100px 100px;
background-position: 0 0, 50px 50px;
See this example live
Using the right units
Don’t use pixels for the sizes without any thought. In some cases, ems make much more sense. For example, when you want to make a lined paper background, you want the lines to actually follow the text. If you use pixels, you have to change the size every time you change font-size. If you set the background-size in ems, it will naturally follow the text and you will only have to update it if you change line-height.
Is it possible?
The shapes that can be achieved with only one gradient are:
stripes
right triangles
circles and ellipses
semicircles and other shapes formed from slicing ellipses horizontally or vertically
You can combine several of them to create squares and rectangles (two right triangles put together), rhombi and other parallelograms (four right triangles), curves formed from parts of ellipses, and other shapes.
Just because you can doesn’t mean you should
Technically, anything can be crafted with these techniques. However, not every pattern is suitable for it. The main advantages of this technique are:
no extra HTTP requests
short code
human-readable code (unlike data URIs) that can be changed without even leaving the CSS file.
Complex patterns that require a large number of gradients are probably better left to SVG or bitmap images, since they negate almost every advantage of this technique:
they are not shorter
they are not really comprehensible – changing them requires much more effort than using an image editor
They still save an HTTP request, but so does a data URI.
I have included some very complex patterns in my gallery, because even though I think they shouldn’t be used in production (except under very exceptional conditions), understanding how they work and coding them helps somebody understand the technology in much more depth.
Another rule of thumb is that if your pattern needs shapes to obscure parts of other shapes, like in the star pattern or the yin yang pattern, then you probably shouldn’t use it. In these patterns, changing the background color requires you to also change the color of these shapes, making edits very tedious.
If a certain pattern is not practicable with a reasonable amount of CSS, that doesn’t mean you should resort to bitmap images. SVG is a very good alternative and is supported by all modern browsers.
Browser support
CSS gradients are supported by Firefox 3.6+, Chrome 10+, Safari 5.1+ and Opera 11.60+ (linear gradients since Opera 11.10). Support is also coming in Internet Explorer when IE10 is released. You can get gradients in older WebKit versions (including most mobile browsers) by using the proprietary -webkit-gradient(), if you really need them.
Epilogue
I hope you find these techniques useful for your own designs. If you come up with a pattern that’s very different from the ones already included, especially if it demonstrates a cool new technique, feel free to send a pull request to the github repo of the patterns gallery. Also, I’m always fascinated to see my techniques put in practice, so if you made something cool and used CSS patterns, I’d love to know about it!

Subliminal User Experience |
The term ‘user experience’ is often used vaguely to quantify common elements of the interaction design process: wireframing, sitemapping and so on. UX undoubtedly involves all of these principles to some degree, but there really is a lot more to it than that.
Good UX is characterized by providing the user with constant feedback as they step through your interface. It means thinking about and providing fallbacks and error resolutions in even the rarest of scenarios. It’s about omitting clutter to make way for the necessary, and using the most fundamental of design tools to influence a user’s path. It means making no assumptions, designing right down to the most distinct details and going one step further every single time. In many cases, good UX is completely subliminal.
There are simple tools and subtleties we can build into our products to enhance the overall experience but, in order to do so, we really have to step beyond where we usually draw the line on what to design.
The purpose of this article is not to provide technical how-tos, as the functionality is, in most cases, quite simple and could be implemented in a myriad of ways. Rather, it will present a handful of ideas for enhancing the experience of an interface at a deeper level of design without relying on the container.
We’ll cover three elements that should get you thinking in the right mindset:
progress activity and post-active states
pseudo-class preloading
buttons and their (mis)behaviour
Progress activity and the post-active state
We’ve long established that we can’t control the devices our products are viewed on, which browser they’ll run in or what connection speed will be used to access them. We accept this all as factual, so why is it so often left to the browser to provide feedback to the user when an event is triggered or an error encountered? The browser isn’t part of the interface — it’s merely a container. A simple, visual recognition of your users’ activity may be all it takes to make or break the product.
Let’s begin with a commonly overlooked case: progress activity.
A user moves their cursor over a hyperlink or button, which is clearly defined as one by the visual language of your content. Upon doing so, they trigger the :hover state to confirm this element is indeed interactive. So far, so good. What happens next is where it starts to fall apart: the user hits this link, presumably triggering an :active state, which is then returned to the normal state upon release. And then what?
From this point on, your user is in limbo. The link has fallen back to either its regular or :visited state. You’ve effectively abandoned them and are relying entirely on the browser they’re using to communicate that something is happening. This poses quite a few problems:
The user may lose focus of what they were doing.
There is little consistency between progress indication in browsers.
The user may not even notice that their action has been acknowledged.
How many times have one or more of these events happened to you due to a lack of communication from the interface?
Think about the differences between Safari and Chrome in this area — two browsers that, when compared to each other, are relatively similar in nature, though this basic feature differs in execution.
Like all aspects of designing the user experience, there is no one true way to fix this problem, but we can introduce details that many users will unconsciously appreciate.
Consider the basic loading indicator. It’s nothing new — in fact, some would argue it’s quite a cliché. However, whether using a spinning wheel or a progress bar, a gif or JavaScript, or something more sophisticated, these simple tools create an illusion of movement, progress and activity. Depending on the implementation, progress indication graphics can significantly increase a user’s perception of the speed in which an event is taking place. Combine this with a cursor change and a lock over the element to prevent double-clicking or reloading, and your chances of keeping your user’s valuable attention have significantly increased.
Demo: Progress activity and the post-active state
This same logic applies to all aspects of defaulting in a browser, from micro-elements like this up to something as simple as a 404 page. The difference in a user’s reaction to hitting the default Apache 404 and a hand-crafted, branded page are phenomenal and there are no prizes for guessing which one they’re more likely to exit from.
Pseudo-class preloading
Another detail that it pays well to look after is the use and abuse of the :hover element and, more importantly, the content revealed by it. Chances are you’re using the :hover pseudo-class somewhere in almost every screen you create. If content is being revealed on :hover and that content takes some time to load, there will inevitably be a delay the first time it is initiated. It appears tacky and half-finished when a tooltip or drop-down loads instantly, only to have its background or supporting elements follow through a second or two later. So, let’s preload the elements we know we’ll need.
A very simple application of this would be to load each file into the default state of a visible element and offset them by a large number. This ensures our elements have loaded and are ready if and when they need to be displayed.
element {
background: url(path/to/image.jpg) -9999em -9999em no-repeat;
}
element .tooltip {
display: none;
}
element:hover .tooltip {
display: block;
background: url(path/to/image.jpg) 0 0;
}
Background images are just one example. Of course, the same logic can apply to any form of revealed content. Using a sprite graphic can also be a clever — albeit tedious — method for achieving the same goal, so if you’re using a sprite, preloading in this way may not be necessary
The differences between preloading and not can only be visualized properly with an actual demonstration.
Demo: Preloading revealed content
Buttons and their (mis)behaviour
Almost all of the time, a button serves just one purpose: to be clicked (or tapped). When a button’s pressed, therefore, if anything other than triggering the desired event occurs, a user naturally becomes frustrated. I often get funny looks when talking about this, but designing the details of a button is something I consider essential.
It goes without saying that a button should always visually recognise :hover and :active states. We can take that one step further and disable some actions that get in the way of pressing the button.
It’s rare that a user would ever want to select and use the text on a button, so let’s cleanly disable it:
element {
-moz-user-select: -moz-none;
-webkit-user-select: none;
user-select: none;
}
If the button is image-based or contains an image, we could also disable user dragging to make sure the image element stays locked to the button:
element {
-moz-user-drag: -moz-none;
-webkit-user-drag: none;
user-drag: none;
}
Demo: A more usable button
Disabling global features like this should be done with utmost caution as it’s very easy to cross the line between enhancement and friction. Cases where this is acceptable are very rare, but it’s a good trick to keep in mind nevertheless. Both Apple’s iCloud and Metalab’s Flow applications use these tools appropriately and to great extent.
You could argue that the visual feedback of having the text selected or image dragged when a user mis-hits the button is actually a positive effect, informing the user that their desired action did not work. However, covering for human error should be a designer’s job, not that of our users. We can (almost) ensure it does work for them by accommodating for errors like this in most cases.
Final thoughts
Designing to this level of detail can seem obsessive, but as a designer and user of many interfaces and applications, I believe it can be the difference between a good user experience and a great one.
The samples you’ve just seen are only a fraction of the detail we can design for. Keep in mind that the demonstrations, code and methods above outline just one way to do this. You may not agree with all of these processes or have the time and desire to consider them, but one fact remains: it’s not the technology, or the way it’s done that’s important — it’s the logic and the concept of designing everything. |

Composing the New Canon: Music, Harmony, Proportion |
Ohne Musik wäre das Leben ein Irrtum
—Friedrich NIETZSCHE, Götzen-Dämmerung, Sprüche und Pfeile 33, 1889
Somehow, music is hardcoded in human beings. It is something we understand and respond to without prior knowledge. Music exercises the emotions and our imaginative reflex, not just our hearing. It behaves so much like our emotions that music can seem to symbolize them, to bear them from one person to another. Not surprisingly, it conjures memories: the word music derives from Greek μουσική (mousike), art of the Muses, whose mythological mother was Mnemosyne, memory. But it can also summon up the blood, console the bereaved, inspire fanaticism, bolster governments and dissenters alike, help us learn, and make web designers dance. And what would Christmas be without music?
Music moves us, often in ways we can’t explain. By some kind of alchemy, music frees us from the elaborate nuisance and inadequacy of words. Across the world and throughout recorded history – and no doubt well before that – people have listened and made (and made out to) music.
[I]t appears probable that the progenitors of man, either the males or females or both sexes, before acquiring the power of expressing their mutual love in articulate language, endeavoured to charm each other with musical notes and rhythm.
—Charles DARWIN, The Descent of Man, and Selection in Relation to Sex, 1871
It’s so integral to humankind, we’ve sent it into space as a totem for who we are. (Who knows? It might be important.) Music is essential, a universal compulsion; as Nietzsche wrote, without music life would be a mistake.
Music, design and web design
There are some obvious and notable similarities between music and visual design. Both can convey mood and evoke emotion but, even under close scrutiny, how they do that remains to a great extent mysterious. Each has formal qualities or parts that can be abstracted, analysed and discussed, often using the same terminology: composition, harmony, rhythm, repetition, form, theme; even colour, texture and tone.
A possible reason for these shared aspects is that both visual design and music are means to connect with people in deep and lasting ways. Furthermore, I believe the connections to be made can complement direct emotional appeal. Certain aesthetic qualities in music work on an unconscious and, it could be argued, universal level. Using musical principles in our designs, then, can help provide the connectedness between content, device and user that we now seek as web designers.
Yet, when we talk about music and web design, the conversation is almost always about the music designers listen to while working, a theme finding its apotheosis in Designers.MX. Sometimes, articles in that dreary list format seek inspiration from music industry websites. There’s even a service offering pre-templated web designs for bands, and at least one book surveyed the landscape back in 2006. Occasionally, discussions broaden somewhat into whether and how different kinds of music can inspire and influence the design work we produce.
Such enquiries, it seems to me, are beside the point. Do I really design differently when I listen to Bach rather than Bacharach? Will the barely restrained energy of Count Basie’s The Kid from Red Bank mean I choose a lively colour palette, and rural, autumnal shades when inspired by Fleet Foxes? Mahler means a thirteen-column layout? Gillian Welch leads to distressed black and white photography? While reflecting the importance we place in music and how it seems to help us in our work, surveys on musical taste and lists of favourite artists fail to recognize that some of the fundamental aesthetic characteristics of music can be adapted and incorporated into modern web design.
Antiphonal geometry
Over recent years, web designers have embraced grid systems as powerful tools to help create good-looking and intuitive user experiences. With the advent of responsive design, these grids and their contents must adapt to the different screen sizes and properties of all kinds of user devices. Finding and using grid values that can scale well and retain or enhance their proportions and relationships while making the user experience meaningful in several different contexts is more important than ever.
In print, this challenge has always started with the dimensions and proportions of the page. Content can thereby be made to belong inside the page and be bound to it. And music has been used for centuries to further this aim. As Robert Bringhurst says in The Elements of Typographical Style:
Indeed, one of the simplest of all systems of page proportions is based on the familiar intervals of the diatonic scale. Pages that embody these basic musical proportions have been in common use in Europe for more than a thousand years.
Very well. But while he goes on to list (from the full chromatic scale, rather than just diatonic) the proportions and the musical intervals they’re based on, Bringhurst fails to mention what they’re ratios of or their potential effects. Shame. In his favour, however, he later touches on how proportions in print might be considered to work:
The page is a piece of paper. It is also a visible and tangible proportion, silently sounding the thoroughbass of the book. On it lies the textblock, which must answer to the page. The two together – page and textblock – produce an antiphonal geometry. That geometry alone can bond the reader to the book. Or conversely, it can put the reader to sleep, or put the reader’s nerves on edge, or drive the reader away.
So what does Bringhurst mean by antiphonal geometry, a phrase that marries the musical to the spatial? By stating that the textblock “must answer to the page”, the implication is that the relationship between the proportions of the page and the shape of the textblock printed on it embodies a spatial (geometrical) call-and-response (antiphony) that can be appealing or not.
Boulton’s new canon
But, as Mark Boulton has pointed out, on the web “there are no edges. There are no ‘pages’. We’ve made them up.” So, what is to be done? In January 2011 at the New Adventures in Web Design conference, Boulton presented his vision of a new canon of web design, a set of principles to guide us as we design the web. There are three overlapping tenets:
design from the content out
create connectedness between the different content elements
bind the content to the web device
Rather than design from the edges in, we need to design layout systems from the content out. To this end, Boulton asserts that grid system design should begin with a constraint, and he suggests we use the size of a fixed content element, such as an advertising unit or image, as a starting point for online grid calculations. Khoi Vinh advocates the same approach in his book, Ordering Disorder: Grid Principles for Web Design.
Boulton’s second and third tenets, however, are more complex and overlap significantly with each other. Connecting the different parts of the content and binding the content to the device share many characteristics and solutions:
adopting ems and percentages as units of size for layout elements
altering text size, line length and line height for different viewport dimensions
providing higher resolution images for devices with greater pixel densities
fluid layout grids, flexible images and responsive design
All can help relate the presentation of the content to its delivery in a certain context.
But how do we determine the relationship between one element of a layout and another? How can we avoid making arbitrary decisions about the relative sizes of parts of our designs? What can we use to connect the parts of our design to one another, and how can we bind the presentation of the content to the user’s device?
Tim Brown’s application of modular typographic scales hints at an answer. In the very useful tool he created for calculating such scales, Brown includes two musical ratios: the perfect fifth (2:3); and the perfect fourth (3:4). Why? Where do they come from? And what do they mean?
Harmonies musical and visual
Fundamental to music are rhythm and harmony.
As any drummer will tell you, without rhythm there is no music. Even when there’s no regular beat, any tune follows a rhythm, however irregular, simply because a change of note is a point of change in the music. Although rhythm, timing and pacing are all relevant to interaction design, right now it’s harmony we’re interested in.
Sometimes harmony is called the vertical aspect of music, and melody the horizontal. But this conceit overlooks the fact that harmony is both vertical and horizontal. A single melodic line, as it is played, implies various sets of harmonies on which it is grounded, whether or not those harmonies are played. So, harmony doesn’t just sit vertically beneath the horizontal melody, but moves horizontally as well, through harmonic progression.
To stretch this arrangement pixel-thin, we could argue that in onscreen design melody is the content, and the layout and arrangement of the content is the harmony. We sometimes say a design is harmonious when the interplay of different elements of a design is pleasing or balanced or in proportion, and the content (the melody) is set off or conveyed well by or appropriate to the design.
We seem to know instinctively whether a layout is harmonious…
In the design of The Great Discontent, the relationships between different elements combine to form a balanced whole.
…or not.
There’s no harmony in the Department for Education’s website because the different parts of the content don’t feel related to one another.
What is it that makes one design harmonious and another dissonant? It’s not just whether things line up, though that’s a start. I believe there are much deeper aesthetic forces at work, forces we can tap into in our onscreen designs. Now, I’m not going start a difficult discussion about aesthetics. For our purposes, we just need to know that it’s the branch of philosophy dealing with the nature of beauty, and the creation and perception of beauty. And among the key components in the perception of beauty are harmony and proportion. These have been part of traditional western aesthetics since Plato (about 2,500 years).
One of the ways we appreciate the beauty of music is through the harmonic intervals we hear. A musical interval is a combination of two notes and it describes the distance between the two pitches. For example, the distance between C and the G above it (if we take C as the tonic or root) is called a perfect fifth.
Left: C to G, a perfect fifth. Right: C and G, not a perfect fifth.
And, to get superficially scientific for a moment, each musical interval can be expressed as a ratio of the wavelength frequencies of the notes; for our perfect fifth, with every two wavelengths of C, there are three of G. And what is a ratio, if not a proportion of one thing to another?
So, simple musical harmony (using what’s known as just intonation1) affords us a set of proportions, expressed as ratios. Where better to apply these ideas of harmony and proportion from music in web design, than grid systems?
A digression: whither φ?
Quite often in our discussions of pure design and aesthetics, we mention the golden ratio and regurgitate the same justifications for its use: roots in antiquity; embodied in classical and Renaissance architecture and art; occurrence in nature; the New Twitter, and so forth (oh, really?).
Yet the ratios of musical intervals from just intonation are equally venerable and much more widespread: described by Pythagorus; employed in Palladian architecture, and printing, books and art from the Renaissance onwards; in modern times, film and television dimensions; standard international paper sizes (ISO 216, the A and B series); and, again and again, screen dimensions – chances are that screen you’re probably looking at right now has the proportions 2:3 (iPhone and iPod Touch), 3:4 (iPad and Kindle), 3:5 (many smartphones), 5:8 or 16:9 (many widescreen monitors), all ratios of musical intervals.
Back to our theme…

As you can see, the simple musical intervals are expressed as ratios of small whole numbers (integers). We can then normalize them as ratios of one, as well as derive percentage values, both in terms of the smaller value to the larger, and vice versa. These are the numbers we can incorporate into our designs. If you’ve ever written something like body { font: 100%/1.5 "Museo Sans", Helvetica, sans-serif; } in your CSS, you’re already using a musical ratio: the perfect fifth.
Modular scales allow us to generate a set of numbers based on a musical interval that can be used for all kinds of typographic and layout decisions to create harmony in a visual design for the web. As Tim Brown said at the 2010 Build conference:
I think that from that most atomic unit – type – whole experiences can resonate, whole experiences can be harmonious. And whole experiences can have a purpose suited to our design intentions.
Once more, with feeling: connectedness
As well as modular scales, there are other methods of incorporating musical interval ratios into our work. Setting the ratio of font size to line height in CSS is one such example. We could also create a typographic hierarchy using the same principle and combining several ratios that we know harmonize well musically in a chord:
body { font-size: 75%; } /* =12px = base size or tonic */
h1 { font-size: 32px; font-size: 2.667rem; }
/* =32px = 3:8 = major eleventh (C→F↑) */
h2 { font-size: 24px; font-size: 2rem; }
/* =24px = 1:2 = octave (C→C↑) */
h3 { font-size: 20px; font-size: 1.667rem; }
/* =20px = 3:5 = major sixth (C→A) */
figcaption, small { font-size: 9px; font-size : 0.75rem }
/* =9px = 3:4 = perfect fourth (C→F) */
Whoa! Hold your reindeer, Santa! How can we know what interval combinations work well together to form chords? Well, I’m a classically trained musician, so perhaps I have an advantage. To avoid a long, technically complex digression into musical harmony, here are a few basic combinations of intervals that are harmonious in one way or another:
unison; major third; perfect fifth; octave
unison; perfect fourth; major sixth; octave
unison; minor third; minor sixth; octave
unison; minor third; diminished fifth; major sixth; octave
This isn’t to say that other combinations can’t be used to interesting effect and particular purpose – they surely can – but I have to make sure there’s something left for you to experiment with in the wee small hours over the holiday. Bear in mind, though, were I to play you two notes from the same scale to form a minor second, for example, you’d probably say it was dissonant and maybe that quality of the 15:16 ratio would be translated to the design.
In the typographic hierarchy above, you’ll notice I used an interval in the higher octave, which affords a broader range of ratios while retaining the harmony. Thus, a perfect fifth (2:3) becomes a major twelfth (1:3), or a major sixth (3:5) becomes a major thirteenth (3:10).
The harmonic ratios can obviously be used as proportions for layout as well, in several different ways:
image width and height (for example, 450×800px = 9:16 = minor seventh)
main content to page width (67%:100% = 2:3 = perfect fifth)
page width to viewport width (80%:100% = 4:5 = major third)
One great benefit of using such ratios in web design work is that they can be applied in responsive web design. Proportional values, based on percentages or equivalent em units, will scale with changing viewports, so your layout and image proportions can be maintained or deliberately changed, as we’re about to find out, across devices.
Small speakers, tall speakers: binding to the device
The musical interval ratios also provide an opportunity, not only to create connectedness between the parts of a layout, but to bind the content to a device – that elusive antiphonal geometry. Just as a textblock and page resonate together, so too can web content and the screen. Earlier, I mentioned that several common screen aspect ratios match musical interval ratios. It would seem, then, that we have a set of proportions that we can use in different ways to establish and retain a sense of harmony that can be based on and change with those contexts. Using musical interval ratios, we can bind the display of our content to the device it’s displayed on.
If you haven’t met already, let me introduce you to the device-aspect-ratio property of CSS media queries.
@media only screen and (device-aspect-ratio: 3/4) { }
@media only screen and (device-aspect-ratio: 480/640) { }
@media only screen and (device-aspect-ratio: 600/800) { }
@media only screen and (device-aspect-ratio: 768/1024) { }
Regardless of the precise pixel values, each of these media queries would apply to devices whose display area has an aspect ratio of 3:4. It works by comparing the device-width with the device-height. (It’s not to be confused with aspect-ratio, which is defined by the width and height of the browser within the device.) The values in the media query are always presented as width/height, with portrait being the default orientation for smartphones and tablets; that is, to match an iPhone screen, you’d use device-aspect-ratio: 2/3, not 3/2, which won’t work.
Here’s a table of the musical intervals with their corresponding screens.

[You might argue that I’m playing fast and loose with the ratios. I suppose, mathematically speaking, 9:16 is not the same as 16:9: I’m no expert. But let’s not throw the baby out with the bath water, particularly at Christmas.]
With this in mind, we can begin to write media queries that will influence various typographic and layout values in line with the aspect ratios of specific screens and in combination with em-based min-width queries that work from smaller, mobile screens to larger, desktop screens.
Here’s a very simple demo page with only some text, an image with a caption and a little basic layout: no seasonal overindulgence here.
Demo: Sample page using device-aspect-ratio media queries based on musical interval ratios
Our initial styles for all devices are based on the perfect fifth, with the major third and octave rounding things out into a harmonious whole, whether or not media queries are supported. For example:
html { font-size: 100%; line-height: 1.5; }
/* font-size:line-height = 16:24 = 2:3 = perfect fifth */
h1 { font-size: 32px; font-size: 2rem; line-height: 1.25; }
/* font-size:line-height = 32:40 = 4:5 = major third
body:h1 = 16:32 = 1:2 = octave */
While we should really consider methods of delivering images appropriate to the screen size, let’s just stick to a single image for all devices. But why don’t we change its aspect ratio from 4:3 to 3:2, to fit with our harmonic scheme? It’s easy enough to do with overflow:hidden on the <figure> element to hide a part of the image, and a negative margin fudge:
figure img { margin: -8.5% 0 0 0; width: 100%; max-width: 100%; }
Our first break point targets devices 320 pixels wide with an aspect ratio of 2:3, namely the iPhone and iPod Touch:
/* 320px = 20×16 */
@media only screen and (min-width: 20em) and (device-aspect-ratio: 2/3) { }
We’re actually already there, of course, as the intervals we’ve chosen resonate with this aspect ratio – the content is already bound to the device.
Our next media query, then, will make some changes to match a different ratio, the major sixth (3:5), which is same as that of many smartphones:
/* 480px = 30×16 */
@media only screen and (min-width: 30em) and (device-aspect-ratio: 3/5) { }
A different aspect ratio might require a change in harmony. For devices with these proportions, we’ll now use the perfect fourth (3:4) and the major sixth (3:5) along with the octave we already have to create a new resonating harmony. For instance, a slightly wider screen means we can increase the line-height to aid the legibility of longer lines:
html { line-height: 1.667; }
/* font-size:line-height = 16:26.672 = 3:5 = major sixth */
h1 { font-size: 32px; font-size: 2rem; line-height: 1.667; }
/* font-size:line-height = 32:53.333 = 3:5 = major sixth
body:h1 = 16:32 = 1:2 = octave */
and we can remove the negative margin to display our 4:3 image in its entirety.
Each screen displays content styled using relationships related to its own proportions. On the left, an iPhone 4 (2:3); on the right, a Samsung Nexus S (3:5). Your mileage may vary.
Another device, another media query. At 768 pixels, screens are wide enough to add columns. The ratios we’ve used for the 3:5 screens include the perfect fourth (3:4) so we don’t need to change any of the font measurements, but we can base the proportions of the columns on the major sixth interval:
article { float: left; width: 56%; }
/* width of main column 3:5 (60% of 100%, major sixth)
incorporating gutter width */
aside { float : right; width : 36%; }
On devices with a 3:4 aspect ratio, this works even better in landscape orientation.
While not every screen over 768 pixels wide will have 3:4 proportions, the range of intervals informing the design ensure harmonious relationships between the different parts of the layout.
For wide screens proper (break point at 1,280 pixels) we can employ a new set of harmonious intervals. Many laptop and desktop screens have a 16:10 aspect ratio, which boils down to 8:5, equivalent to the minor sixth (5:8). Combined with a minor third (5:6) and the octave (1:2), this creates a new harmony appropriate to these devices. Let’s increase the font size and change the image’s aspect ratio to match:
html { font-size: 120%; line-height: 1.6; }
/* font-size increased for wider screens from 16px to 19.2px
(5:6 = minor third)
font-size:line-height = 19.2:30.72 = 5:8 = minor sixth */
figure img { margin: -12.5% 0 0 ; }
/* using -ve margin combined with overflow:hidden
on the figure element
to crop the image from 4:3 to 8:5 = minor sixth */
A wide screen with a 8:5 (16:10) aspect ratio and an image to match.
With more pixels at our disposal, we can also now use the musical interval ratios to determine the width of the layout, and change the column proportions as well:
section { margin: 0 auto; width: 83.333%; }
/* content width:screen width = 5:6 = minor third */
article { width: 60%; }
/* width of main column 5:8 (62.5% of 100%, minor sixth)
incorporating gutter width */
aside { width: 35%; }
With some carefully targeted media queries, we can begin to reach towards fulfilling the second and third tenets of Boulton’s new canon for web design: connecting the parts of content through relationships embodied in the layout design; and binding the content to the devices people use to access it.
Coda
Musical interval ratios and screen aspect ratios reveal more than convenient correspondence. These proportions work on a deep aesthetic level. Much is claimed for the golden ratio φ, but none of the screens pervading our lives use it. Perhaps that’s an accident of technology, but can making screens to φ’s proportions be more difficult or expensive than 2:3 or 3:4 or 16:10? Here, then, is not just one but a set of proportions with a uniquely human focus, originating in nature, recognized in antiquity, fundamental still.
We find music to be an art steeped with meaning, yet, unlike literary and representational arts, purely instrumental music has no obvious semantic content. It boasts an ability to express emotions while remaining an abstract art in some sense, which makes it very like design. These days, we’re rightly encouraged to design for emotion, to make our users’ experience meaningful, seductive, delightful. Using musical ideas and principles in our designs can help achieve those ends.
Let’s not be naïve, of course; designing web pages is even less like composing music than it’s like designing for print. In visual design, the eye will always be sovereign to the ear; following these principles will only get us so far. We cannot truly claim that a carefully composed web page layout will have the same qualities and effect as any musical patterns that inform it. In music, a set of intervals is always harmonious in relation to other sets of intervals: music rarely stands still. What aspect ratios will future screens take? Already today there is great variation in devices and support for media queries (and within that, support for device-aspect-ratio). And what of non-western musical traditions? Or rhythm, form, tempo and dynamics? What I’ve demonstrated above is only a suggestion, a tentative exploration of one possible way forward.
But as our discipline matures and we become more articulate about what we do, we must look longer and deeper into areas of human endeavour already rich with value. Music is a fertile ground to explore and has the potential to yield up new approaches for web design.
Footnotes
Just intonation is a system of tuning that uses small integers to describe the musical intervals, based initially on the perfect fifth, that most consonant of intervals. Simple instruments such as vibrating strings and natural horns, as well as unaccompanied voices, tend to fall into just intonation naturally. |

Defending the Perimeter Against Web Widgets |
On July 14, 1789, citizens of Paris stormed the Bastille, igniting a revolution that toppled the French monarchy. On July 14 of this year, there was a less dramatic (though more tweeted) takedown: The Deck network, which delivers advertising to some of the most popular web design and culture destinations, was down for about thirty minutes. During this period, most partner sites running ads from The Deck could not be viewed as result.
A few partners were unaffected (aside from not having an ad to display). Fortunately, Dribbble, was one of them. In this article, I’ll discuss outages like this and how to defend against them. But first, a few qualifiers: The Deck has been rock solid – this is the only downtime we’ve witnessed since joining in June. More importantly, the issues in play are applicable to any web widget you might add to your site to display third-party content.
Down and out
Your defense is only as good as its weakest link. Web pages are filled with links, some of which threaten the ability of your page to load quickly and correctly. If you want your site to work when external resources fail, you need to identify the weak links on your site. In this article, we’ll talk about web widgets as a point of failure and defensive JavaScript techniques for handling them.
Widgets 101
Imagine a widget that prints out a Pun of the Day on your site. A simple technique for both widget provider and consumer is for the provider to expose a URL:
http://widgetjonesdiary.com/punoftheday.js
which returns a JavaScript file like this:
document.write("<h2>The Pun of the Day</h2><p>Where do frogs go for beers after work? Hoppy hour!</p>");
The call to document.write() injects the string passed into the document where it is called. So to display the widget on your page, simply add an external script tag where you want it to appear:
<div class="punoftheday">
<script src="http://widgetjonesdiary.com/punoftheday.js"></script>
<!-- Content appears here as output of script above -->
</div>
This approach is incredibly easy for both provider and consumer. But there are implications…
document.write()… or wrong?
As in the example above, scripts may perform a document.write() to inject HTML. Page rendering halts while a script is processed so any output can be inlined into the document. Therefore, page rendering speed depends on how fast the script returns the data. If an external JavaScript widget hangs, so does the page content that follows. It was this scenario that briefly stalled partner sites of The Deck last summer.
The elegant solution
To make our web widget more robust, calls to document.write() should be avoided. This can be achieved with a technique called JSONP (AKA JSON with padding). In our example, instead of writing inline with document.write(), a JSONP script passes content to a callback function:
publishPun("<h2>Pun of the Day</h2><p>Where do frogs go for beers after work? Hoppy hour!</p>");
Then, it’s up to the widget consumer to implement a callback function responsible for displaying the content. Here’s a simple example where our callback uses jQuery to write the content into a target <div>:
<!-- Where widget content should appear -->
<div class="punoftheday"></div>
…
<br />
function publishPun(content) {
$(‘.punoftheday’).html(content); // Writes content display location<br />
}<br />
View Example 1
Even if the widget content appears at the top of the page, our script can be included at the bottom so it’s non-blocking: a slow response leaves page rendering unaffected. It simply invokes the callback which, in turn, writes the widget content to its display destination.
The hack
But what to do if your provider doesn’t support JSONP? This was our case with The Deck. Returning to our example, I’m reminded of computer scientist David Wheeler’s statement, “All problems in computer science can be solved by another level of indirection… Except for the problem of too many layers of indirection.”
In our case, the indirection is to move the widget content into position after writing it to the page. This allows us to place the widget <script> tag at the bottom of the page so rendering won’t be blocked, but still display the widget in the target. The strategy:
Load widget content into a hidden <div> at the bottom of the page.
Move the loaded content from the hidden <div> to its display location.
and the code:
<!-- Where widget content should appear -->
<div class="punoftheday"></div>

$(‘.punoftheday’).append($(‘.loading-dock’).children(‘:gt(0)’));<br />
View Example 2
After the external punoftheday.js script has processed, the rendered HTML will look as follows:
<div class="loading-dock hidden">
<script src="http://widgetjonesdiary.com/punoftheday.js"></script>
<h2>Pun of the Day</h2>
<p>Where do frogs go for beers after work? Hoppy hour!</p>
</div>
The ‘loading-dock’ <div> now includes the widget content, albeit hidden from view (if we’ve styled the ‘hidden’ class with display: none). There’s just one more step: move the content to its display destination. This line of jQuery (from above) does the trick:
$('.punoftheday').append($('.loading-dock').children(':gt(0)'));
This selects all child elements in the ‘loading-doc’ <div> except the first – the widget <script> tag which generated it – and moves it to the display destination. Worth noting is the :gt(0) jQuery selector extension, which allows us to exclude the first (in a 0-based array) child element – the widget <script> tag – from selection.
Since all of this happens at the bottom of the page, just before the </body> tag, no rendering has to wait on the external widget script. The only thing that fails if our widget hangs is… the widget itself. Our weakest link has been strengthened and so has our site. DE-FENSE! |

Extracting the Content |
As we throw away our canvas in approaches and yearn for a content-out process, there remains a pain point: the Content. It is spoken of in the hushed tones usually reserved for Lord Voldemort. The-thing-that-someone-else-is-responsible-for-that-must-not-be-named.
Designers and developers have been burned before by not knowing what the Content is, how long it is, what style it is and when the hell it’s actually going to be delivered, in internet eons past. Warily, they ask clients for it. But clients don’t know what to make, or what is good, because no one taught them this in business school. Designers struggle to describe what they need and when, so the conversation gets put off until it’s almost too late, and then everyone is relieved that they can take the cop-out of putting up a blog and maybe some product descriptions from the brochure.
The Content in content out.
I’m guessing, as a smart, sophisticated, and, may I say, nicely-scented reader of the honourable and venerable tradition of 24 ways, that you sense something better is out there. Bunches of boxes to fill in just don’t cut it any more in a responsive web design world. The first question is, how are you going to design something to ensure users have the easiest access to the best Content, if you haven’t defined at the beginning what that Content is? Of course, it’s more than possible that your clients have done lots of user research before approaching you to start this project, and have a plethora of finely tuned Content for you to design with.
Have you finished laughing yet? Alright then. Let’s just assume that, for whatever reason of gross oversight, this hasn’t happened. What next?
Bringing up Content for the first time with a client is like discussing contraception when you’re in a new relationship. It might be awkward and either party would probably rather be doing something else, but it needs to be broached before any action happens (that, and it’s disastrous to assume the other party has the matter in hand). If we can’t talk about it, how can we expect people to be doing it right and not making stupid mistakes? That being the case, how do we talk about Content? Let’s start by finding a way to talk about it without blushing and scuffing our shoes. And there’s a reason I’ve been treating Content as a Proper Noun.
The first step, and I mean really-first-step-way-back-at-the-beginning-of-the-project-while-you-are-still-scoping-out-what-the-hell-you-might-do-for-each-other-and-it’s-still-all-a-bit-awkward-like-a-first-date, is for you to explain to the client how important it is that you, together, work out what is important to your users as part of the user experience design, so that your users get the best user experience. The trouble is that, in most cases, this would lead to blank stares, possibly followed by a light cough and a query about using Comic Sans because it seems friendly.
Let’s start by ensuring your clients understand the task ahead. You see, all the time we talk about the Content we do our clients a big disservice. Content is poorly defined. It looms over a project completion point like an unscalable (in the sense of a dozen stacked Kilimanjaros), seething, massive, singular entity. The Content.
Defining the problem.
We should really be thinking of the Content as ‘contents’; as many parts that come together to form a mighty experience, like hit 90s kids’ TV show Mighty Morphin Power Rangers*.
*For those of you who might have missed the Power Rangers, they were five teenagers with attitude, each given crazy mad individual skillz and a coloured lycra suit from an alien overlord. In return, they had to fight a new monster of the week using their abilities and weaponry in sync (even if the audio was not) and then, finally, in thrilling combination as a Humongous Mechanoid Machine of Awesome. They literally joined their individual selves, accessories and vehicles into a big robot. It was a toy manufacturer’s wet dream.
So, why do I say Content is like the Power Rangers? Because Content is not just a humongous mecha. It is a combination of well-crafted pieces of contents that come together to form a well-crafted humongous mecha. Of Content.
The Red Power Ranger was always the leader. You can imagine your text contents, found on about pages, product descriptions, blog articles, and so on, as being your Red Power Ranger.
Maybe your pictures are your Yellow Power Ranger; video is Blue (not used as much as the others, but really impressive when given a good storyline); maybe Pink is your infographics (it’s wrong to find it sexier than the other equally important Rangers, but you kind of do anyway). And so on.
These bits of content – Red Text Ranger, Yellow Picture Ranger and others – often join together on a page, like they are teaming up to fight the bad guy in an action scene, and when they all come together (your standard workaday huge mecha) in a launched site, that’s when Content becomes an entity.
While you might have a vision for the whole site, Content rarely works that way. Of course, you keep your eye on the bigger prize, the completion of your mega robot, but to get there you need to assemble your working parts, the cogs and springs of contents that will mesh together to finally create your Humongous Mecha of Content. You create parts and join them to form a whole. (It’s rarely seamless; often we need to adjust as we go, but we can create our Mecha’s blueprint by making sure we have all the requisite parts.)
The point here is the order these parts were created. No alien overlord plans a Humongous Mechanoid and then thinks, “Gee, how can I split this into smaller fighting units powered by teenagers in snazzy shiny suits?” No toy manufacturer goes into production of a mega robot, made up of model mecha vehicles with detachable arsenal, without thinking how they will easily fit back together to form the ‘Buy all five now to create the mega robot’ set. No good contents are created as a singular entity and chunked up to be slotted in to place any which way, into the body of a site.
Think contents, not the Content. Think of contents as smaller units, or as a plural. The Content is what you have at the end. The contents are what you are creating and they are easy to break down. You are no longer scaling the unscalable. You can draw the map and plot the path, page by page, section by section.
The page table is your friend
To do this, I use a page table. A page table is a simple table template you can create in the word processor of your choice, that you use to tell you everything about the contents of a page – everything except the contents itself.
Here’s a page table I created for an employee’s guide to redundancy in the alpha.gov.uk website:
Guide to redundancy for employees
Page objective: Provide specific information for employees who are facing redundancy about the process, their options and next steps.
Source content: directgov page on Redundancy.
Scope: In scope
Page title
An employee’s guide to redundancy
Priority content
Message: You have rights as an employee facing redundancy
Method: A guide written in plain English, with links to appropriate additional content.
A video guide (out of scope).
Covers the stages of redundancy and rights for those in trade unions and not in trade unions. Glossary of unfamiliar terms.
Call to action: Read full guide, act to explore redundancy actions, benefits or new employment.
Assets: link to redundancy calculator.
Secondary
Related items, or popular additional links.
Additional tools, such as search and suggestions.
location set v not set states
microcopy encouraging location set where location may make a difference to the content – ie, Scotland/Northern Ireland.
Tertiary
Footer and standard links.
Content creation: Content exists but was created within the constraints of the previous CMS. Review, correct and edit where necessary.
Maintenance: should be flagged for review upon advice from Department of Work and Pensions, and annually.
Technology/Publishing/Policy implications: Should be reviewed once the glossary styles have been decided. No video guide in scope at this time, so languages should be simple and screen reader friendly.
Reliance on third parties: None, all content and source exists in house.
Outstanding questions: None.

This particular page table template owes a lot to Brain Traffic’s version found in Kristina Halvorson’s book Content Strategy for the Web. With smaller clients than, say, the government, I might use something a bit more casual. With clients who like timescales and deadlines, I might turn it into a covering sheet, with signatures and agreements from two departments who have to work together to get the piece done on time.
I use page tables, and the process of working through them, to reassure clients that I understand the task they face and that I can help them break it down section by section, page stack to page, down to product descriptions and interaction copy. About 80% of my clients break into relieved smiles. Most clients want to work with you to produce something good, they just don’t understand how, and they want you to show them the mountain path on the map. With page tables, clients can understand that with baby steps they can break down their content requirements and commission content they need in time for the designers to work with it (as opposed to around it). If I was Santa, these clients would be on my nice list for sure.
My own special brand of Voldemort-content-evilness comes in how I wield my page tables for the other 20%. Page tables are not always thrilling, I’ll admit. Sometimes they get ignored in favour of other things, yet they are crucial to the continual growth and maintenance of a truly content-led site. For these naughty list clients who, even when given the gift of the page table, continually say “Ooh, yes. Content. Right”, I have a special gift. I have a stack of recycled paper under my desk and a cheap black and white laser printer. And I print a blank page table for every conceivable page I can find on the planned redesign. If I’m feeling extra nice, I hole punch them and put them in a fat binder.
There is nothing like saying, “This is all the contents you need to have in hand for launch”, and the satisfying thud the binder makes as it hits the table top, to galvanize even the naughtiest clients to start working with you to create the content you need to really create in a content-out way. |

Displaying Icons with Fonts and Data- Attributes |
Traditionally, bitmap formats such as PNG have been the standard way of delivering iconography on websites. They’re quick and easy, and it also ensures they’re as pixel crisp as possible. Bitmaps have two drawbacks, however: multiple HTTP requests, affecting the page’s loading performance; and a lack of scalability, noticeable when the page is zoomed or viewed on a screen with a high pixel density, such as the iPhone 4 and 4S.
The requests problem is normally solved by using CSS sprites, combining the icon set into one (physically) large image file and showing the relevant portion via background-position. While this works well, it can get a bit fiddly to specify all the positions. In particular, scalability is still an issue. A vector-based format such as SVG sounds ideal to solve this, but browser support is still patchy.
The rise and adoption of web fonts have given us another alternative. By their very nature, they’re not only scalable, but resolution-independent too. No need to specify higher resolution graphics for high resolution screens!
That’s not all though:
Browser support: Unlike a lot of new shiny techniques, they have been supported by Internet Explorer since version 4, and, of course, by all modern browsers. We do need several different formats, however!
Design on the fly: The font contains the basic graphic, which can then be coloured easily with CSS – changing colours for themes or :hover and :focus styles is done with one line of CSS, rather than requiring a new graphic. You can also use CSS3 properties such as text-shadow to add further effects. Using -webkit-background-clip: text;, it’s possible to use gradient and inset shadow effects, although this creates a bitmap mask which spoils the scalability.
Small file size: specially designed icon fonts, such as Drew Wilson’s Pictos font, can be as little as 12Kb for the .woff font. This is because they contain fewer characters than a fully fledged font. You can see Pictos being used in the wild on sites like Garrett Murray’s Maniacal Rage.
As with all formats though, it’s not without its disadvantages:
Icons can only be rendered in monochrome or with a gradient fill in browsers that are capable of rendering CSS3 gradients. Specific parts of the icon can’t be a different colour.
It’s only appropriate when there is an accompanying text to provide meaning. This can be alleviated by wrapping the text label in a tag (I like to use <b> rather than <span>, due to the fact that it’s smaller and isn’ t being used elsewhere) and then hiding it from view with text-indent:-999em.
Creating an icon font can be a complex and time-consuming process. While font editors can carry out hinting automatically, the best results are achieved manually.
Unless you’re adept at creating your own fonts, you’re restricted to what is available in the font. However, fonts like Pictos will cover the most common needs, and icons are most effective when they’re using familiar conventions.
The main complaint about using fonts for icons is that it can mean adding a meaningless character to our markup. The good news is that we can overcome this by using one of two methods – CSS generated content or the data-icon attribute – in combination with the :before and :after pseudo-selectors, to keep our markup minimal and meaningful.
Our simple markup looks like this:
<a href="/basket" class="icon basket">View Basket</a>
Note the multiple class attributes. Next, we’ll import the Pictos font using the @font-face web fonts property in CSS:
@font-face {
font-family: 'Pictos';
src: url('pictos-web.eot');
src: local('☺'),
url('pictos-web.woff') format('woff'),
url('pictos-web.ttf') format('truetype'),
url('pictos-web.svg#webfontIyfZbseF') format('svg');
}
This rather complicated looking set of rules is (at the time of writing) the most bulletproof way of ensuring as many browsers as possible load the font we want. We’ll now use the content property applied to the :before pseudo-class selector to generate our icon. Once again, we’ll use those multiple class attribute values to set common icon styles, then specific styles for .basket. This helps us avoid repeating styles:
.icon {
font-family: 'Pictos';
font-size: 22px:
}
.basket:before {
content: "$";
}
What does the :before pseudo-class do? It generates the dollar character in a browser, even when it’s not present in the markup. Using the generated content approach means our markup stays simple, but we’ll need a new line of CSS, defining what letter to apply to each class attribute for every icon we add.
data-icon is a new alternative approach that uses the HTML5 data- attribute in combination with CSS attribute selectors. This new attribute lets us add our own metadata to elements, as long as its prefixed by data- and doesn’t contain any uppercase letters. In this case, we want to use it to provide the letter value for the icon. Look closely at this markup and you’ll see the data-icon attribute.
<a href="/basket" class="icon" data-icon="$">View Basket</a>
We could add others, in fact as many as we like.
<a href="/" class="icon" data-icon="k">Favourites</a>
<a href="/" class="icon" data-icon="t">History</a>
<a href="/" class="icon" data-icon="@">Location</a>
Then, we need just one CSS attribute selector to style all our icons in one go:
.icon:before {
content: attr(data-icon);
/* Insert your fancy colours here */
}
By placing our custom attribute data-icon in the selector in this way, we can enable CSS to read the value of that attribute and display it before the element (in this case, the anchor tag). It saves writing a lot of CSS rules. I can imagine that some may not like the extra attribute, but it does keep it out of the actual content – generated or not.
This could be used for all manner of tasks, including a media player and large simple illustrations. See the demo for live examples. Go ahead and zoom the page, and the icons will be crisp, with the exception of the examples that use -webkit-background-clip: text as mentioned earlier.
Finally, it’s worth pointing out that with both generated content and the data-icon method, the letter will be announced to people using screen readers. For example, with the shopping basket icon above, the reader will say “dollar sign view basket”. As accessibility issues go, it’s not exactly the worst, but could be confusing. You would need to decide whether this method is appropriate for the audience. Despite the disadvantages, icon fonts have huge potential. |

Beyond Web Mechanics – Creating Meaningful Web Design |
It was just over three years ago when I embarked on becoming a web designer, and the first opinion piece about the state of web design I came across was a conference talk by Elliot Jay Stocks called ‘Destroy the Web 2.0 Look’. Elliot’s presentation was a call to arms, a plea to web designers the world over to stop the endless reproductions of the so called ‘Web 2.0 look’.
Three and a half years on from Elliot’s talk, what has changed? Well, from an aesthetic standpoint, not a whole lot. The Web 2.0 look has evolved, but it’s still with us and much of the web remains filled with cookie cutter websites that bear a striking resemblance to one another. This wouldn’t matter so much if these websites were selling comparable services or products, but they’re not. They look similar, they follow the same web design trends; their aesthetic style sends out a very similar message, yet they’re selling completely different services or products. How can you be communicating effectively with your users when your online book store is visually indistinguishable from an online cosmetic store? This just doesn’t make sense.
I don’t want to belittle the current version of the Web 2.0 look for the sake of it. I want to talk about the opportunity we have as web designers to create more meaningful experiences for the people using our websites. Using design wisely gives us the ability to communicate messages, ideas and attitudes that our users will understand and connect with.
Being human
As human beings we respond emotionally to everything around us – people, objects, posters, packaging or websites. We also respond in different ways to different kinds of aesthetic design and style. We care about style and aesthetics deeply, whether we realise it or not. Aesthetic design has the power to attract or repel. We often make decisions based purely on aesthetics and style – and don’t retailers the world over know it! We connect attitudes and strongly held beliefs to style. Individuals will proudly associate themselves with a certain style or aesthetic because it’s an expression of who they are. You know that old phrase, ‘Don’t judge a book by its cover’? Well, the problem is that people do, so it’s important we get the cover right.
Much is made of how to structure web pages, how to create a logical information hierarchy, how to use layout and typography to clearly communicate with your users. It’s important, however, not to mistake clarity of information or legibility with getting your message across. Few users actually read websites word by word: it’s far more likely they’ll just scan the page. If the page is copy-heavy and nothing grabs their attention, they may well just move on. This is why it’s so important to create a visual experience that actually means something to the user.
Meaningful design
When we view a poster or website, we make split-second assessments and judgements of what is in front of us. Our first impressions of what a website does or who it is aimed at are provoked by the style and aesthetic of the website. For example, with clever use of colour, typography, graphic design and imagery we can communicate to users that an organisation is friendly, edgy, compassionate, fun or environmentally conscious.
Using a certain aesthetic we can convey the personality of that organisation, target age ranges, different sexes or cultural groups, communicate brand attributes, and more. We can make our users feel like they’re part of something and, perhaps even more importantly, we can make new users want to be a part of something. And we can achieve all this before the user has read a single word.
By establishing a website’s aesthetic and creating a meaningful visual language, a design is no longer just a random collection of pretty gradients that have been plucked out of thin air. There can be a logic behind the design decisions we make. So, before you slap another generic piece of ribbon or an ultra shiny icon into the top-left corner of your website, think about why you are doing it. If you can’t come up with a reason better than “I saw it on another website”, it’s probably a poor application of style.
Design and style
There are a number of reasons why the web suffers from a lack meaningful design. Firstly, there are too many preconceptions of what a website should look like. It’s too easy for designers to borrow styles from other websites, thereby limiting the range of website designs we see on the web. Secondly, many web designers think of aesthetic design as of secondary importance, which shouldn’t be the case. Designing websites that are accessible and easy to use is, of course, very important but this is the very least a web designer should be delivering. Easy to use websites should come as standard – it’s equally important to create meaningful, compelling and beautiful experiences for everyone who uses our websites. The aesthetics of your site are part of the design, and to ignore this and play down the role of aesthetic design is just a wasted opportunity.
No compromise necessary
Easy to use, accessible websites and beautiful, meaningful aesthetics are not mutually exclusive. The key is to apply style and aesthetic design appropriately. We need to think about who and what we’re designing for and ask ourselves why we’re applying a certain kind of aesthetic style to our design. If you do this, there’s no reason why effective, functional design should come at the expense of jaw-dropping, meaningful aesthetics.
Web designers need to understand the differences between functional design and aesthetic design but, even more importantly, they need to know how to make them work together. It’s combining these elements of design successfully that makes for the best web design in the world. |

Put Yourself in a Corner |
Some backstory, and a shameful confession
For the first couple years of high school I was one of those jerks who made only the minimal required effort in school. Strangely enough, how badly I behaved in a class was always in direct proportion to how skilled I was in the subject matter. In the subjects where I was confident that I could pass without trying too hard, I would give myself added freedom to goof off in class.
Because I was a closeted lit-nerd, I was most skilled in English class. I’d devour and annotate required reading over the weekend, I knew my biblical and mythological allusions up and down, and I could give you a postmodern interpretation of a text like nobody’s business. But in class, I’d sit in the back and gossip with my friends, nap, or scribble patterns in the margins of my textbooks. I was nonchalant during discussion, I pretended not to listen during lectures. I secretly knew my stuff, so I did well enough on tests, quizzes, and essays. But I acted like an ass, and wasn’t getting the most I could out of my education.
The day of humiliation, but also epiphany
One day in Ms. Kaney’s AP English Lit class, I was sitting in the back doodling. An earbud was dangling under my sweater hood, attached to the CD player (remember those?) sitting in my desk. Because of this auditory distraction, the first time Ms. Kaney called my name, I barely noticed. I definitely heard her the second time, when she didn’t call my name so much as roar it. I can still remember her five feet frame stomping across the room and grabbing an empty desk. It screamed across the worn tile as she slammed it next to hers. She said, “This is where you sit now.” My face gets hot just thinking about it.
I gathered my things, including the CD player (which was now impossible to conceal), and made my way up to the newly appointed Seat of Shame. There I sat, with my back to the class, eye-to-eye with Ms. Kaney. From my new vantage point I couldn’t see my friends, or the clock, or the window. All I saw were Ms. Kaney’s eyes, peering at me over her reading glasses while I worked. In addition to this punishment, I was told that from now on, not only would I participate in class discussions, but I would serve detention with her once a week until an undetermined point in the future.
During these detentions, Ms. Kaney would give me new books to read, outside the curriculum, and added on to my normal homework. They ranged from classics to modern novels, and she read over my notes on each book. We’d discuss them at length after class, and I grew to value not only our private discussions, but the ones in class as well. After a few weeks, there wasn’t even a question of this being punishment. It was heaven, and I was more productive than ever.
To the point
Please excuse this sentimental story. It’s not just about honoring a teacher who cared enough to change my life, it’s really about sharing a lesson. The most valuable education Ms. Kaney gave me had nothing to do with literature. She taught me that I (and perhaps other people who share my special brand of crazy) need to be put in a corner to flourish. When we have physical and mental constraints applied, we accomplish our best work.
For those of you still reading, now seems like a good time to insert a pre-emptive word of mediation. Many of you, maybe all of you, are self-disciplined enough that you don’t require the rigorous restrictions I use to maximize productivity. Also, I know many people who operate best in a stimulating and open environment. I would advise everyone to seek and execute techniques that work best for them. But, for those of you who share my inclination towards daydreams and digressions, perhaps you’ll find something useful in the advice to follow.
In which I pretend to be Special Agent Olivia Dunham
Now that I’m an adult, and no longer have Ms. Kaney to reign me in, I have to find ways to put myself in the corner. By rejecting distraction and shaping an environment designed for intense focus, I’m able to achieve improved productivity.
Lately I’ve been obsessed with the TV show Fringe, a sci-fi series about an FBI agent and her team of genius scientists who save the world (no, YOU’RE a nerd). There’s a scene in the show where the primary character has to delve into her subconscious to do extraordinary things, and she accomplishes this by immersing herself in a sensory deprivation tank. The premise is this: when enclosed in a space devoid of sound, smell, or light, she will enter a new plane of consciousness wherein she can tap into new levels of perception.
This might sound a little nuts, but to me this premise has some real-world application. When I am isolated from distraction, and limited to only the task at hand, I’m able to be productive on a whole new level. Since I can’t actually work in an airtight iron enclosure devoid of input, I find practical ways to create an interruption-free environment.
Since I work from home, many of my methods for coping with distractions wouldn’t be necessary for my office-bound counterpart. However for some of you 9-to-5-ers, the principles will still apply.
Consider your visual input
First, I have to limit my scope to the world I can (and need to) affect. In the largest sense, this means closing my curtains to the chaotic scene of traffic, birds, the post office, a convenience store, and generally lovely weather that waits outside my window. When the curtains are drawn and I’m no longer surrounded by this view, my sphere is reduced to my desk, my TV, and my cat. Sometimes this step alone is enough to allow me to focus.
But, my visual input can be whittled down further still. For example, the desk where I usually keep my laptop is littered with twelve owl figurines, a globe, four books, a three-pound weight, and various nerdy paraphernalia (hard drives, Wacom tablets, unnecessary bluetooth accessories, and so on). It’s not so much a desk as a dumping ground for wacky flea market finds and impulse technology buys. Therefore, in addition to this Official Desk, I have an adult version of Ms. Kaney’s Seat of Shame. It’s a rusty old student’s desk I picked up at the Salvation Army, almost an exact replica of the model Ms. Kaney dragged across the classroom all those years ago. This tiny reproduction Seat of Shame is literally in a corner, where my only view is a blank wall. When I truly need to focus, this is where I take refuge, with only a notebook and a pencil (and occasionally an iPad).
Find out what works for your ears
Even from my limited sample size of two people, I know there are lots of different ways to cope with auditory distraction. I prefer silence when focused on independent work, and usually employ some form of a white noise generator. I’ve yet to opt for the fancy ‘real’ white noise machines; instead, I use a desktop fan or our allergy filter machine. This is usually sufficient to block out the sounds of the dishwasher and the cat, which allows me to think only about the task of hand.
My boyfriend, the other half of my extensive survey, swears by another method. He calls it The Wall of Sound, and it’s basically an intense blast of raucous music streamed directly into his head. The outcome of his technique is really the same as mine; he’s blocking out unexpected auditory input. If you can handle the grating sounds of noisy music while working, I suggest you give The Wall of Sound a try.
Don’t count the minutes
When I sat in the original Seat of Shame in lit class, I could no longer see the big classroom clock slowly ticking away the seconds until lunch. Without the marker of time, the class period often flew by. The same is true now when I work; the less aware of time I am, the less it feels like time is passing too quickly or slowly, and the more I can focus on the task (not how long it takes).
Nowadays, to assist in my effort to forget the passing of time, I sometimes put a sticky note over the clock on my monitor. If I’m writing, I’ll use an app like WriteRoom, which blocks out everything but a simple text editor.
There are situations when it’s not advisable to completely lose track of time. If I’m working on a project with an hourly rate and a tight scope, or if I need to be on time to a meeting or call, I don’t want to lose myself in the expanse of the day. In these cases, I’ll set an alarm that lets me know it’s time to reign myself back in (or on some days, take a shower).
Put yourself in a mental corner, too
When Ms. Kaney took action and forced me to step up my game, she had the insight to not just change things physically, but to challenge me mentally as well. She assigned me reading material outside the normal coursework, then upped the pressure by requiring detailed reports of the material. While this additional stress was sometimes uncomfortable, it pushed me to work harder than I would have had there been less of a demand. Just as there can be freedom in the limitations of a distraction-free environment, I’d argue there is liberty in added mental constraints as well.
Deadlines as a constraint
Much has been written about the role of deadlines in the creative process, and they seem to serve different functions in different cases. I find that deadlines usually act as an important constraint and, without them, it would be nearly impossible for me to ever consider a project finished. There are usually limitless ways to improve upon the work I do and, if there’s no imperative for me to be done at a certain point, I will revise ad infinitum. (Hence, the personal site redesign that will never end – Coming Soon, Forever!). But if I have a clear deadline in mind, there’s a point when the obsessive tweaking has to stop. I reach a stage where I have to gather up the nerve to launch the thing.
Putting the pro in procrastination
Sometimes I’ve found that my tendency to procrastinate can help my productivity. (Ducks, as half the internet throws things at her.) I understand the reasons why procrastination can be harmful, and why it’s usually a good idea to work diligently and evenly towards a goal. I try to divide my projects up in a practical way, and sometimes I even pull it off. But for those tasks where you work aimlessly and no focus comes, or you find that every other to-do item is more appealing, sometimes you’re forced to bring it together at the last moment. And sometimes, this environment of stress is a formula for magic. Often when I’m down to the wire and have no choice but to produce, my mind shifts towards a new level of clarity. There’s no time to endlessly browse for inspiration, or experiment with convoluted solutions that lead nowhere.
Obviously a life lived perpetually on the edge of a deadline would be a rather stressful one, so it’s not a state of being I’d advocate for everyone, all the time. But every now and then, the work done when I’m down to the wire is my best.
Keep one toe outside your comfort zone
When I’m choosing new projects to take on, I often seek out work that involves an element of challenge. Whether it’s a design problem that will require some creative thinking, or a coding project that lends itself to using new technology like HTML5, I find a manageable level of difficulty to be an added bonus. The tension that comes from learning a new skill or rethinking an old standby is a useful constraint, as it keeps the work interesting, and ensures that I continue learning.
There you have it
Well, I think I’ve spilled most of my crazy secrets for forcing my easily distracted brain to focus. As with everything we web workers do, there are an infinite number of ways to encourage productivity. I hope you’ve found a few of these to be helpful, and please share your personal techniques in the comments. Have a happy and productive new year! |

Speed Up Your Site with Delayed Content |
Speed remains one of the most important factors influencing the success of any website, and the first rule of performance (according to Yahoo!) is reducing the number of HTTP requests. Over the last few years we’ve seen techniques like sprites and combo CSS/JavaScript files used to reduce the number of HTTP requests. But there’s one area where large numbers of HTTP requests are still a fact of life: the small avatars attached to the comments on articles like this one.
Avatars
Many sites like 24 ways use a fantastic service called Gravatar to provide user images. As a user, you can sign up to Gravatar, give them your e-mail address, and upload an image to represent you. Sites can then include your image by generating a one way hash of your e-mail address and using that to build an image URL. For example, the markup for the comments on this page looks something like this:
<div>
<h4><a href="http://allinthehead.com/">
<img src="http://www.gravatar.com/avatar.php?gravatar_id=13734b0cb20708f79e730809c29c3c48&size=100" class="gravatar" alt="" height="100" width="100" />
Drew McLellan
</a></h4>
<p>This is a great article!</p>
</div>
The Gravatar URL contains two parts. 100 is the size in pixels of the image we want. 13734b0cb20708f79e730809c29c3c48 is an MD5 digest of Drew’s e-mail address. Using MD5 means we can request an image for a user without sharing their e-mail address with anyone who views the source of the page.
So what’s wrong with avatars?
The problem is that a popular article can easily get hundreds of comments, and every one of them means another image has to be individually requested from Gravatar’s servers. Each request is small and the Gravatar servers are fast but, when you add them up, it can easily add seconds to the rendering time of a page. Worse, they can delay the loading of more important assets like the CSS required to render the main content of the page.
These images aren’t critical to the page, and don’t need to be loaded up front. Let’s see if we can delay loading them until everything else is done. That way we can give the impression that our site has loaded quickly even if some requests are still happening in the background.
Delaying image loading
The first problem we find is that there’s no way to prevent Internet Explorer, Chrome or Safari from loading an image without removing it from the HTML itself. Tricks like removing the images on the fly with JavaScript don’t work, as the browser has usually started requesting the images before we get a chance to stop it.
Removing the images from the HTML means that people without JavaScript enabled in their browser won’t see avatars. As Drew mentioned at the start of the month, this can affect a large number of people, and we can’t completely ignore them. But most sites already have a textual name attached to each comment and the avatars are just a visual enhancement. In most cases it’s OK if some of our users don’t see them, especially if it speeds up the experience for the other 98%.
Removing the images from the source of our page also means we’ll need to put them back at some point, so we need to keep a record of which images need to be requested. All Gravatar images have the same URL format; the only thing that changes is the e-mail hash. Storing this is a great use of HTML5 data attributes.
HTML5 data what?
Data attributes are a new feature in HTML5. The latest version of the spec says:
A custom data attribute is an attribute in no namespace whose name starts with the string “data-”, has at least one character after the hyphen, is XML-compatible, and contains no characters in the range U+0041 to U+005A (LATIN CAPITAL LETTER A to LATIN CAPITAL LETTER Z).
[…]
Custom data attributes are intended to store custom data private to the page or application, for which there are no more appropriate attributes or elements. These attributes are not intended for use by software that is independent of the site that uses the attributes.
In other words, they’re attributes of an HTML element that start with “data-” which you can use to share data with scripts running on your site. They’re great for adding small bits of metadata that don’t fit into an existing markup pattern the way microformats do.
Let’s see this in action
Take a look at the markup for comments again:
<div>
<h4><a href="http://allinthehead.com/">
<img src="http://www.gravatar.com/avatar.php?gravatar_id=13734b0cb20708f79e730809c29c3c48&size=100" class="gravatar" alt="" height="100" width="100" />
Drew McLellan
</a></h4>
<p>This is a great article!</p>
</div>
Let’s replace the <img> element with a data-gravatar-hash attribute on the <a> element:
<div>
<h4><a href="http://allinthehead.com/" data-gravatar-hash="13734b0cb20708f79e730809c29c3c48">
Drew McLellan
</a></h4>
<p>This is a great article!</p>
</div>
Once we’ve done this, we’ll need a small bit of JavaScript to find all these attributes, and replace them with images after the page has loaded. Here’s an example using jQuery:
$(window).load(function() {
$('a[data-gravatar-hash]').prepend(function(index){
var hash = $(this).attr('data-gravatar-hash')
return '<img width="100" height="100" alt="" src="http://www.gravatar.com/avatar.php?size=100&gravatar_id=' + hash + '">'
})
})
This code waits until everything on the page is loaded, then uses jQuery.prepend to insert an image into every link containing a data-gravatar-hash attribute. It’s short and relatively simple, but in tests it reduced the rendering time of a sample page from over three seconds to well under one.
Finishing touches
We still need to consider the appearance of the page before the avatars have loaded. When our script adds extra content to the page it will cause a browser reflow, which is visually annoying. We can avoid this by using CSS to reserve some space for each image before it’s inserted into the HTML:
#comments div {
padding-left: 110px;
min-height: 100px;
position: relative;
}
#comments div h4 img {
display: block;
position: absolute;
top: 0;
left: 0;
}
In a real world example, we’ll also find that the HTML for a comment is more varied as many users don’t provide a web page link. We can make small changes to our JavaScript and CSS to handle this case.
Put this all together and you get this example.
Taking this idea further
There’s no reason to limit this technique to sites using Gravatar; we can use similar code to delay loading any images that don’t need to be present immediately. For example, this year’s redesigned Flickr photo page uses a “data-defer-src” attribute to describe any image that doesn’t need to be loaded straight away, including avatars and map tiles.
You also don’t have to limit yourself to loading the extra resources once the page loads. You can get further bandwidth savings by waiting until the user takes an action before downloading extra assets. Amazon has taken this tactic to the extreme on its product pages – extra content is loaded as you scroll down the page.
So next time you’re building a page, take a few minutes to think about which elements are peripheral and could be delayed to allow more important content to appear as quickly as possible. |

Finding Your Way with Static Maps |
Since the introduction of the Google Maps service in 2005, online maps have taken off in a way not really possible before the invention of slippy map interaction. Although quickly followed by a plethora of similar services from both commercial and non-commercial parties, Google’s first-mover advantage, and easy-to-use developer API saw Google Maps become pretty much the de facto mapping service.
It’s now so easy to add a map to a web page, there’s no reason not to. Dropping an iframe map into your page is as simple as embedding a YouTube video.
But there’s one crucial drawback to both the solution Google provides for you to drop into your page and the code developers typically implement themselves – they don’t work without JavaScript.
A bit about JavaScript
Back in October of this year, The Yahoo! Developer Network blog ran some tests to measure how many visitors to the Yahoo! home page didn’t have JavaScript available or enabled in their browser. It’s an interesting test when you consider that the audience for the Yahoo! home page (one of the most visited pages on the web) represents about as mainstream a sample as you’ll find. If there’s any such thing as an ‘average Web user’ then this is them.
The results surprised me. It varied from region to region, but at most just two per cent of visitors didn’t have JavaScript running. To be honest, I was expecting it to be higher, but this quote from the article caught my attention:
While the percentage of visitors with JavaScript disabled seems like a low number, keep in mind that small percentages of big numbers are also big numbers.
That’s right, of course, and it got me thinking about what that two per cent means. For many sites, two per cent is the number of visitors using the Opera web browser, using IE6, or using Mobile Safari.
So, although a small percentage of the total, users without JavaScript can’t just be forgotten about, and catering for them is at the very heart of how the web is supposed to work.
Starting with content in HTML, we layer on presentation with CSS and then enhance interactivity with JavaScript. If anything fails along the way or the network craps out, or a browser just doesn’t support one of the technologies, the user still gets something they can work with.
It’s progressive enhancement – also known as doing our jobs properly.
Sorry, wasn’t this about maps?
As I was saying, the default code Google provides, and the example code it gives to developers (which typically just gets followed ‘as is’) doesn’t account for users without JavaScript. No JavaScript, no content.
When adding the ability to publish maps to our small content management system Perch, I didn’t want to provide a solution that only worked with JavaScript. I had to go looking for a way to provide maps without JavaScript, too.
There’s a simple solution, fortunately, in the form of static map tiles. All the various slippy map services use a JavaScript interface on top of what are basically rendered map image tiles. Dragging the map loads in more image tiles in the direction you want to view. If you’ve used a slippy map on a slow connection, you’ll be familiar with seeing these tiles load in one by one.
The Static Map API
The good news is that these tiles (or tiles just like them) can be used as regular images on your site. Google has a Static Map API which not only gives you a handy interface to retrieve a tile for the exact area you need, but also allows you to place pins, and zoom and centre the tile so that the image looks just so.
This means that you can create a static, non-JavaScript version of your slippy map’s initial (or ideal) state to load into your page as a regular image, and then have the JavaScript map hijack the image and make it slippy.
Clearly, that’s not going to be a perfect solution for every map’s requirements. It doesn’t allow for panning, zooming or interrogation without JavaScript. However, for the majority of straightforward map uses online, a static map makes a great alternative for those visitors without JavaScript.
Here’s the how
Retrieving a static map tile is staggeringly easy – it’s just a case of forming a URL with the correct arguments and then using that as the src of an image tag.
<img src="http://maps.google.com/maps/api/staticmap
?center=Bethlehem+Israel
&zoom=5
&size=540x280
&maptype=satellite
&markers=color:red|31.4211,35.1144
&sensor=false"
width="540" height="280" alt="Map of Bethlehem, Israel" />
As you can see, there are a few key options that we pass along to the base URL. All of these should be familiar to anyone who’s worked with the JavaScript API.
center determines the point on which the map is centred. This can be latitude and longitude values, or simply an address which is then geocoded.
zoom sets the zoom level.
size is the pixel dimensions of the image you require.
maptype can be roadmap, satellite, terrain or hybrid.
markers sets one or more pin locations. Markers can be labelled, have different colours, and so on – there’s quite a lot of control available.
sensor states whether you are using a sensor to determine the user’s location. When just embedding a map in a web page, set this to false.
There are many options, including plotting paths and setting the image format, which can all be found in the straightforward documentation.
Adding to your page
If you’ve worked with the JavaScript API, you’ll know that it needs a container element which you inject the map into:
<div id="map"></div>
All you need to do is put your static image inside that container:
<div id="map">
<img src="http://maps.google.com/maps/api/staticmap[...]" />
</div>
And then, in your JavaScript, find the image and remove it. For example, with jQuery you’d simply use:
$('#map img').remove();
Why not use a <noscript> element around the image? You could, and that would certainly work fine for browsers that do not support JavaScript. What that won’t cover, however, is the situation where the browser has JavaScript support but, for whatever reason, the JavaScript doesn’t run. This could be due to network issues, an aggressive corporate firewall, or even just a bug in your code. So for that reason, we put the image in for all browsers that show images, and then remove it when the JavaScript is successfully running.
See an example in action
About rate limits
The Google Static Map API limits the requests per site viewer – currently at one thousand distinct maps per day per viewer. So, for most sites you really don’t need to worry about the rate limit. Requests for the same tile aren’t normally counted, as the tile has already been generated and is cached. You can embed the images direct from Google and let it worry about the distribution and caching.
In conclusion
As you can see, adding a static map alongside your dynamic map for those users without JavaScript is very easy indeed. There may not be a huge percentage of web visitors browsing without JavaScript but, as we’ve seen, a small percentage of a big number is still a big number. When it’s so easy to add a static map, can you really justify not doing it? |

“Probably, Maybe, No”: The State of HTML5 Audio |
With the hype around HTML5 and CSS3 exceeding levels not seen since 2005’s Ajax era, it’s worth noting that the excitement comes with good reason: the two specifications render many years of feature hacks redundant by replacing them with native features. For fun, consider how many CSS2-based rounded corners hacks you’ve probably glossed over, looking for a magic solution. These days, with CSS3, the magic is border-radius (and perhaps some vendor prefixes) followed by a coffee break.
CSS3’s border-radius, box-shadow, text-shadow and gradients, and HTML5’s <canvas>, <audio> and <video> are some of the most anticipated features we’ll see put to creative (ab)use as adoption of the ‘new shiny’ grows. Developers jumping on the cutting edge are using subsets of these features to little detriment, in most cases. The more popular CSS features are design flourishes that can degrade nicely, but the current audio and video implementations in particular suffer from a number of annoyances.
The new shiny: how we got here
Sound involves one of the five senses, a key part of daily life for most – and yet it has been strangely absent from HTML and much of the web by default. From a simplistic perspective, it seems odd that HTML did not include support for the full multimedia experience earlier, despite the CD-ROM-based craze of the early 1990s. In truth, standards like HTML can take much longer to bake, but eventually deliver the promise of a lowered barrier to entry, consistent implementations and shiny new features now possible ‘for free’ just about everywhere.
<img> was introduced early and naturally to HTML, despite having some opponents at the time. Perhaps <audio> and <video> were avoided, given the added technical complexity of decoding various multi-frame formats, plus the hardware and bandwidth limitations of the era. Perhaps there were quarrels about choosing a standard format or – more simply – maybe these elements just weren’t considered to be applicable to the HTML-based web at the time. In any event, browser plugins from programs like RealPlayer and QuickTime eventually helped to fill the in-page audio/video gap, handling <object> and <embed> markup which pointed to .wav, .avi, .rm or .mov files. Suffice it to say, the experience was inconsistent at best and, on the standards side of the fence right now, so is HTML5 in terms of audio and video.
: the theory
As far as HTML goes, the code for <audio> is simple and logical. Just as with <img>, a src attribute specifies the file to load. Pretty straightforward – sounds easy, right?
<audio src="mysong.ogg" controls>
<!-- alternate content for unsupported case -->
Download <a href="mysong.ogg">mysong.ogg</a>;
</audio>
Ah, if only it were that simple. The first problem is that the OGG audio format, while ‘free’, is not supported by some browsers. Conversely, nor is MP3, despite being a de facto standard used in all kinds of desktop software (and hardware). In fact, as of November 2010, no single audio format is commonly supported across all major HTML5-enabled browsers.
What you end up writing, then, is something like this:
<audio controls>
<source src="mysong.mp3" />
<source src="mysong.ogg" />
<!-- alternate content for unsupported case, maybe Flash, etc. -->
Download <a href="mysong.ogg">mysong.ogg</a> or <a href="mysong.mp3">mysong.mp3</a>
</audio>
Keep in mind, this is only a ‘first class’ experience for the HTML5 case; also, for non-supported browsers, you may want to look at another inline player (object/embed, or a JavaScript plus Flash API) to have inline audio. You can imagine the added code complexity in the case of supporting ‘first class’ experiences for older browsers, too.
: the caveats
With <img>, you typically don’t have to worry about format support – it just works – and that’s part of what makes a standard wonderful. JPEG, PNG, BMP, GIF, even TIFF images all render just fine if for no better reason, perhaps, than being implemented during the ‘wild west’ days of the web. The situation with <audio> today reflects a very different – read: business-aware – environment in 2010. (Further subtext: There’s a lot of [potential] money involved.) Regrettably, this is a collision of free and commercial interests, where the casualty is ultimately the user. Second up in the casualty list is you, the developer, who has to write additional code around this fragmented support.
The HTML5 audio API as implemented in JavaScript has one of the most un-computer-like responses I’ve ever seen, and inspired the title of this post. Calling new Audio().canPlayType('audio/mp3'), which queries the system for format support according to a MIME type, is supposed to return one of “probably”, “maybe”, or “no”. Sometimes, you’ll just get a null or empty string, which is also fun. A “maybe” response does not guarantee that a format will be supported; sometimes audio/mp3 gives “maybe,” but then audio/mpeg; codecs="mp3" will give a more-solid “probably” response. This can vary by browser or platform, too, depending on native support – and finally, the user may also be able to install codecs, extending support to include other formats. (Are you excited yet?)
Damn you, warring formats!
New market and business opportunities go hand-in-hand with technology developments. What we have here is certainly not failure to communicate; rather, we have competing parties shouting loudly in public in attempts to influence mindshare towards a de facto standard for audio and video. Unfortunately, the current situation means that at least two formats are effectively required to serve the majority of users correctly.
As it currently stands, we have the free and open source software camp of OGG Vorbis/WebM and its proponents (notably, Mozilla, Google and Opera in terms of browser makers), up against the non-free, proprietary and ‘closed’ camp of MP3 and MPEG4/HE-AAC/H.264 – which is where you’ll find commitments from Apple and Microsoft, among others. Apple is likely in with H.264 for the long haul, given its use of the format for its iTunes music store and video offerings.
It is generally held that H.264 is a technically superior format in terms of file size versus quality, but it involves intellectual property and, in many use cases, requires licensing fees. To be fair, there is a business model with H.264 and much has been invested in its development, but this approach is not often the kind that wins over the web. On that front, OGG/WebM may eventually win for being a ‘free’ format that does not involve a licensing scheme.
Closed software and tools ideologically clash with the open nature of the web, which exists largely thanks to free and open technology. Because of philosophical and business reasons, support for audio and video is fragmented across browsers adopting HTML5 features. It does not help that a large amount of audio and video currently exists in non-free MP3 and MPEG-4 formats. Adoption of <audio> and <video> may be slowed, since it is more complex than <img> and may feel ‘broken’ to developers when edge cases are encountered. Furthermore, the HTML5 spec does not mandate a single required format. The end result is that, as a developer, you must currently provide at least both MP3 and OGG, for example, to serve most existing HTML5-based user agents.
Transitioning to
There will be some growing pains as developers start to pick up the new HTML5 shiny, while balancing the needs of current and older agents that don’t support either <audio> or the preferred format you may choose (for example, MP3). In either event, Flash or other plugins can be used as done traditionally within HTML4 documents to embed and play the relevant audio.
The SoundManager 2 page player demo in action.
Ideally, HTML5 audio should be used whenever possible with Flash as the backup option. A few JavaScript/Flash-based audio player projects exist which balance the two; in attempting to tackle this problem, I develop and maintain SoundManager 2, a JavaScript sound API which transparently uses HTML5 Audio() and, if needed, Flash for playing audio files. The internals can get somewhat ugly, but the transition between HTML4 and HTML5 is going to be just that – and even with HTML5, you will need some form of format fall-back in addition to graceful degradation.
It may be safest to fall back to MP3/MP4 formats for inline playback at this time, given wide support via Flash, some HTML5-based browsers and mobile devices. Considering the amount of MP3/MP4 media currently available, it is wiser to try these before falling through to a traditional file download process.
Early findings
Here is a brief list of behavioural notes, annoyances, bugs, quirks and general weirdness I have found while playing with HTML5-based audio at time of writing (November 2010):
Apple iPad/iPhone (iOS 4, iPad 3.2+)
Only one sound can be played at a time. If a second sound starts, the first is stopped.
No auto-play allowed. Sounds follow the pop-up window security model and can only be started from within a user event handler such as onclick/touch, and so on. Otherwise, playback attempts silently fail.
Once started, a sequence of sounds can be created or played via the ‘finish’ event of the previous sound (for example, advancing through a playlist without interaction after first track starts).
iPad, iOS 3.2: Occasional ‘infinite loop’ bug seen where audio does not complete and stop at a sound’s logical end – instead, it plays again from the beginning. Might be specific to example file format (HE-AAC) encoded from iTunes.
Apple Safari, OS X Snow Leopard 10.6.5
Critical bug: Safari 4 and 5 intermittently fail to load or play HTML5 audio on Snow Leopard due to bug(s) in QuickTime X and/or other underlying frameworks. Known Apple ‘radar’ bug: bugs.webkit.org #32159 (see also, test case.) Amusing side note: Safari on Windows is fine.
Apple Safari, Windows
Food for thought: if you download “Safari” alone on Windows, you will not get HTML5 audio/video support (tested in WinXP). You need to download “Safari + QuickTime” to get HTML5 audio/video support within Safari. (As far as I’m aware, Chrome, Firefox and Opera either include decoders or use system libraries accordingly. Presumably IE 9 will use OS-level APIs.)
General Quirks
Seeking and loading, ‘progress’ events, and calculating bytes loaded versus bytes total should not be expected to be linear, as users can arbitrarily seek within a sound. It appears that some support for HTTP ranges exists, which adds a bit of logic to UI code. Browsers seem to vary slightly in their current implementations of these features.
The onload event of a sound may be of little relevance, if non-linear loading is involved (see above note re: seeking).
Interestingly (perhaps I missed it), the current spec does not seem to specify a panning or left/right channel mix option.
The preload attribute values may vary slightly between browsers at this time.
Upcoming shiny: HTML5 Audio Data API
With access to audio data, you can incorporate waveform and spectrum elements that make your designs react to music.
The HTML5 audio spec does a good job covering the basics of playback, but did not initially get into manipulation or generation of audio on-the-fly, something Flash has had for a number of years now. What if JavaScript could create, monitor and change audio dynamically, like a sort of audio <canvas> element? With that kind of capability, many dynamic audio processing features become feasible and, when combined with other media, can make for some impressive demos.
What started as a small idea among a small group of audio and programming enthusiasts grew to inspire a W3C audio incubator group, and continued to establish the Mozilla Audio Data API. Contributors wrote a patch for Firefox which was reviewed and revised, and is now slated to be in the public release of Firefox 4. Some background and demos are also detailed in an article from the BBC R&D blog.
There are plenty of live demos to see, which give an impression of the new creative ideas this API enables. Many concepts are not new in themselves, but it is exciting to see this sort of thing happening within the native browser context.
Mozilla is not alone in this effort; the WebKit folks are also working on a JavaScriptAudioNode interface, which implements similar audio buffering and sample elements.
The future?
It is my hope that we’ll see a common format emerge in terms of support across the major browsers for both audio and video; otherwise, support will continue to be fragmented and mildly frustrating to develop for, and that can impede growth of the feature. It’s a big call, but if <img> had lacked a common format back in the wild west era, I doubt the web would have grown to where it is today.
Complaints and nitpicks aside, HTML5 brings excellent progress on the browser multimedia front, and the first signs of native support are a welcome improvement given all audio and video previously relied on plugins. There is good reason to be excited. While there is room for more, support could certainly be much worse – and as tends to happen with specifications, the implementations targeting them should improve over time.
Note: Thanks to Nate Koechley, who suggested the Audio().canPlayType() response be part of the article title. |

Golden Spirals |
As building blocks go, the rectangle is not one to overwhelm the designer with decisions. On the face of it, you have two options: you can set the width, and the height. But despite this apparent simplicity, there are combinations of width and height that can look unbalanced. If a rectangle is too tall and slim, it might appear precarious. If it is not tall enough, it may simply look flat. But like a guitar string that’s out of tune, you can tweak the proportions little by little until a rectangle feels, as Goldilocks said, just right.
A golden rectangle has its height and width in the golden ratio, which is approximately 1:1.618. These proportions have long been recognised as being aesthetically harmonious. Whether through instruction or by intuition, artists have understood how to exploit these proportions over the centuries. Examples can be found in classical architecture, medieval book construction, and even in the recent #newtwitter redesign.
A mathematical curiosity
The golden rectangle is unique, in that if you remove a square section from it, what is left behind is itself a golden rectangle. The removal of a square can be repeated on the rectangle that is left behind, and then repeated again, as many times as you like. This means that the golden rectangle can be treated as a building block for recursive patterns. In this article, we will exploit this property to build a golden spiral, using only HTML and CSS.
The markup
The HTML we’ll use for this study is simply a series of nested <div>s.
<body>
<div id="container">
<div class="cycle">

The first of these has the class cycle, and so does every fourth ancestor thereafter. The spiral completes a cycle every four steps, so this class allows styles to be reused on <div>s that appear at the same position in each cycle.
Golden proportions
To create our spiral we are going to exploit the unique properties of the golden rectangle, so our first priority is to ensure that we have a golden rectangle to begin with. If we pick a length for the short edge – say, 288 pixels – we can then calculate the length of the long edge by multiplying this value by 1.618. In this case, 288 × 1.618 = 466, so our starting point will be a <div> with these properties:
#container > div {
width: 466px;
height: 288px;
}
The greater than symbol is used here to single out the immediate child of the #container element, without affecting the grandchild or any of the more distant descendants.
We could go on to specify the precise pixel dimensions of every child element, but that means doing a lot of sums. It would be much easier if we just specified the dimensions for each element as a percentage of the width and height of its parent. This also has the advantage that if you change the size of the outermost container, all nested elements would be resized automatically – something that we shall exploit later.
The approximate value of 38.2% can be derived from (100 × 1 − phi) ÷ phi, where the Greek letter phi (ϕ) stands for the golden ratio. The value of phi can be expressed as phi = (1 + √5 ) ÷ 2, which is approximately 1.618. You don’t have to understand the derivation to use it. Just remember that if you start with a golden rectangle, you can slice 38.2% from it to create a new golden rectangle.
This can be expressed in CSS quite simply:
.cycle,
.cycle > div > div {
height: 38.2%;
width: 100%;
}
.cycle > div,
.cycle > div > div > div {
width: 38.2%;
height: 100%;
}
You can see the result so far by visiting Demo One. With no borders or shading, there is nothing to see yet, so let’s address that next.
Shading with transparency
We’ll need to apply some shading to distinguish each segment of the spiral from its neighbours. We could start with a white background, then progress through shades of grey: #eee, #ddd, #ccc and so on, but this means hard-coding the background-color for every element. A more elegant solution would be to use the same colour for every element, but to make each one slightly transparent.
The nested <div>s that we are working with could be compared to layers in Photoshop. By applying a semi-transparent shade of grey, each successive layer can build on top of the darker layers beneath it. The effect accumulates, causing each successive layer to appear slightly darker than the last. In his 2009 article for 24 ways, Drew McLellan showed how to create a semi-transparent effect by working with RGBA colour. Here, we’ll use the colour black with an alpha value of 0.07.
#container div { background-color: rgba(0,0,0,0.07) }
Note that I haven’t used the immediate child selector here, which means that this rule will apply to all <div> elements inside the #container, no matter how deeply nested they are. You can view the result in Demo Two. As you can see, the golden rectangles alternate between landscape and portrait orientation.
Demo Three).
CSS3 specification indicates that a percentage can be used to set the border-radius property, but using percentages does not achieve consistent results in browsers today. Luckily, if you specify a border-radius in pixels using a value that is greater than the width and height of the element, then the resulting curve will use the shorter length side as its radius. This produces exactly the effect that we want, so we’ll use an arbitrarily high value of 10,000 pixels for each border-radius:
.cycle {
border-radius: 0px;
border-bottom-left-radius: 10000px;
}
.cycle > div {
border-radius: 0px;
border-bottom-right-radius: 10000px;
}
.cycle > div > div {
border-radius: 0px;
border-top-right-radius: 10000px;
}
.cycle > div > div > div {
border-radius: 0px;
border-top-left-radius: 10000px;
}
Note that the specification for the border-radius property is still in flux, so it is advisable to use vendor-specific prefixes. I have omitted them from the example above for the sake of clarity, but if you view source on Demo Four then you’ll see that the actual styles are not quite as brief.
Filling the available space
We have created an approximation of the Golden Spiral using only HTML and CSS. Neat! It’s a shame that it occupies just a fraction of the available space. As a finishing touch, let’s make the golden spiral expand or contract to use the full space available to it.
Ideally, the outermost container should use the full available width or height that could accomodate a rectangle of golden proportions. This behaviour is available for background images using the “ background-size: contain; property, but I know of no way to make block level HTML elements behave in this fashion (if I’m missing something, please enlighten me). Where CSS fails to deliver, JavaScript can usually provide a workaround. This snippet requires jQuery:
$(document).ready(function() {
var phi = (1 + Math.sqrt(5))/2;
$(window).resize(function() {
var goldenWidth = windowWidth = $(this).width(),
goldenHeight = windowHeight = $(this).height();
if (windowWidth/windowHeight > phi) {
// panoramic viewport – use full height
goldenWidth = windowHeight * phi;
} else {
// portrait viewport – use full width
goldenHeight = windowWidth / phi;
};
$("#container > div.cycle")
.width(goldenWidth)
.height(goldenHeight);
}).resize();
});
You can view the result by visiting Demo Five.
Is it just me, or can you see an elephant in there?
You can probably think of many ways to enhance this further, but for this study we’ll leave it there. It has been a good excuse to play with proportions, positioning and the immediate child selector, as well as new CSS3 features such as border-radius and RGBA colours. If you are not already designing with golden proportions, then perhaps this will inspire you to begin. |

Calculating Color Contrast |
Some websites and services allow you to customize your profile by uploading pictures, changing the background color or other aspects of the design. As a customer, this personalization turns a web app into your little nest where you store your data. As a designer, letting your customers have free rein over the layout and design is a scary prospect. So what happens to all the stock text and images that are designed to work on nice white backgrounds? Even the Mac only lets you choose between two colors for the OS, blue or graphite! Opening up the ability to customize your site’s color scheme can be a recipe for disaster unless you are flexible and understand how to find maximum color contrasts.
In this article I will walk you through two simple equations to determine if you should be using white or black text depending on the color of the background. The equations are both easy to implement and produce similar results. It isn’t a matter of which is better, but more the fact that you are using one at all! That way, even with the craziest of Geocities color schemes that your customers choose, at least your text will still be readable.
Let’s have a look at a range of various possible colors. Maybe these are pre-made color schemes, corporate colors, or plucked from an image.
Now that we have these potential background colors and their hex values, we need to find out whether the corresponding text should be in white or black, based on which has a higher contrast, therefore affording the best readability. This can be done at runtime with JavaScript or in the back-end before the HTML is served up.
There are two functions I want to compare. The first, I call ’50%’. It takes the hex value and compares it to the value halfway between pure black and pure white. If the hex value is less than half, meaning it is on the darker side of the spectrum, it returns white as the text color. If the result is greater than half, it’s on the lighter side of the spectrum and returns black as the text value.
In PHP:
function getContrast50($hexcolor){
return (hexdec($hexcolor) > 0xffffff/2) ? 'black':'white';
}
In JavaScript:
function getContrast50(hexcolor){
return (parseInt(hexcolor, 16) > 0xffffff/2) ? 'black':'white';
}
It doesn’t get much simpler than that! The function converts the six-character hex color into an integer and compares that to one half the integer value of pure white. The function is easy to remember, but is naive when it comes to understanding how we perceive parts of the spectrum. Different wavelengths have greater or lesser impact on the contrast.
The second equation is called ‘YIQ’ because it converts the RGB color space into YIQ, which takes into account the different impacts of its constituent parts. Again, the equation returns white or black and it’s also very easy to implement.
In PHP:
function getContrastYIQ($hexcolor){
$r = hexdec(substr($hexcolor,0,2));
$g = hexdec(substr($hexcolor,2,2));
$b = hexdec(substr($hexcolor,4,2));
$yiq = (($r*299)+($g*587)+($b*114))/1000;
return ($yiq >= 128) ? 'black' : 'white';
}
In JavaScript:
function getContrastYIQ(hexcolor){
var r = parseInt(hexcolor.substr(0,2),16);
var g = parseInt(hexcolor.substr(2,2),16);
var b = parseInt(hexcolor.substr(4,2),16);
var yiq = ((r*299)+(g*587)+(b*114))/1000;
return (yiq >= 128) ? 'black' : 'white';
}
You’ll notice first that we have broken down the hex value into separate RGB values. This is important because each of these channels is scaled in accordance to its visual impact. Once everything is scaled and normalized, it will be in a range between zero and 255. Much like the previous ’50%’ function, we now need to check if the input is above or below halfway. Depending on where that value is, we’ll return the corresponding highest contrasting color.
That’s it: two simple contrast equations which work really well to determine the best readability.
If you are interested in learning more, the W3C has a few documents about color contrast and how to determine if there is enough contrast between any two colors. This is important for accessibility to make sure there is enough contrast between your text and link colors and the background.
There is also a great article by Kevin Hale on Particletree about his experience with choosing light or dark themes. To round it out, Jonathan Snook created a color contrast picker which allows you to play with RGB sliders to get values for YIQ, contrast and others. That way you can quickly fiddle with the knobs to find the right balance.
Comparing results
Let’s revisit our color schemes and see which text color is recommended for maximum contrast based on these two equations.
If we use the simple ’50%’ contrast function, we can see that it recommends black against all the colors except the dark green and purple on the second row. In general, the equation feels the colors are light and that black is a better choice for the text.
The more complex ‘YIQ’ function, with its weighted colors, has slightly different suggestions. White text is still recommended for the very dark colors, but there are some surprises. The red and pink values show white text rather than black. This equation takes into account the weight of the red value and determines that the hue is dark enough for white text to show the most contrast.
As you can see, the two contrast algorithms agree most of the time. There are some instances where they conflict, but overall you can use the equation that you prefer. I don’t think it is a major issue if some edge-case colors get one contrast over another, they are still very readable.
Now let’s look at some common colors and then see how the two functions compare. You can quickly see that they do pretty well across the whole spectrum.
In the first few shades of grey, the white and black contrasts make sense, but as we test other colors in the spectrum, we do get some unexpected deviation. Pure red #FF0000 has a flip-flop. This is due to how the ‘YIQ’ function weights the RGB parts. While you might have a personal preference for one style over another, both are justifiable.
In this second round of colors, we go deeper into the spectrum, off the beaten track. Again, most of the time the contrasting algorithms are in sync, but every once in a while they disagree. You can select which you prefer, neither of which is unreadable.
Conclusion
Contrast in color is important, especially if you cede all control and take a hands-off approach to the design. It is important to select smart defaults by making the contrast between colors as high as possible. This makes it easier for your customers to read, increases accessibility and is generally just easier on the eyes.
Sure, there are plenty of other equations out there to determine contrast; what is most important is that you pick one and implement it into your system.
So, go ahead and experiment with color in your design. You now know how easy it is to guarantee that your text will be the most readable in any circumstance. |

Go Forth and Make Awesomeness |
We’ve all dreamed of being a superhero: maybe that’s why we’ve ended up on the web—a place where we can do good deeds and celebrate them on a daily basis.
Wear your dreams
At age four, I wore my Wonder Woman Underoos around my house, my grandparents’ house, our neighbor’s house, and even around the yard. I wanted to be a superhero when I grew up. I was crushed to learn that there is no school for superheroes—no place to earn a degree in how to save the world from looming evil. Instead, I—like everyone else—was destined to go to ordinary school to focus on ABCs and 123s. Even still, I want to save the world.
Intend your goodness
Random acts of kindness make a difference. Books, films, and advertising campaigns tout random acts of kindness and the positive influence they can have on the world. But why do acts of kindness have to be so random? Why can’t we intend to be kind? A true superhero wakes each morning intending to perform selfless acts for the community. Why can’t we do the same thing?
As a child, my mother taught me to plan to do at least three good deeds each day. And even now, years later, I put on my invisible cape looking for ways to do good.
Here are some examples:
slowing down to allow another driver in before me from the highway on-ramp
bringing a co-worker their favorite kind of coffee or tea
sharing my umbrella on a rainy day
holding a door open for someone with full hands
listening intently when someone shares a story
complimenting someone on a job well done
thanking someone for a job well done
leaving a constructive, or even supportive comment on someone’s blog
As you can see, these acts are simple. Doing good and being kind is partially about being aware—aware of the words we speak and the actions we take. Like superheroes, we create our own code of conduct to live by. Hopefully, we choose to put the community before ourselves (within reason) and to do our best not to damage it as we move through our lives.
Take a bite out of the Apple
With some thought, we can weave this type of thinking and action into our business choices. We can take the simple acts of kindness concept and amplify it a bit. With this amplification, we can be a new kind of superhero.
In 1997, during a presentation, Steve Jobs stated Apple’s core value in a simple, yet powerful, sentence:
We believe that people with passion can change the world for the better.
Apple fan or not, those are powerful words.
Define your core
Every organization must define its core values. Core values help us to frame, recognize, and understand the principles our organization embodies and practices. It doesn’t matter if you’re starting a new organization or you want to define values within an existing organization. Even if you’re a freelancer, defining core values will help guide your decisions and actions.
If you can, work as a team to define core values. Gather the people who are your support system—your business partners, your colleagues, and maybe even a trusted client—this is now your core value creation team. Have a brainstorming session with your team. Let ideas flow. Give equal weight to the things people say. You may not hear everything you thought you might hear—that’s OK. You want the session to be free-flowing and honest. Ask yourself and your team questions like:
What do you think my/our/your core values are?
What do you think my/our/your priorities are?
What do you think my/our/your core values should be?
What do you think my/our/your priorities should be?
How do you think I/we should treat customers, clients, and each other?
How do we want others to treat us?
What are my/our/your success stories?
What has defined these experiences as successful?
From this brainstorming session, you will craft your superhero code of conduct. You will decide what you will and will not do. You will determine how you will and will not act. You’re setting the standards that you will live and work by—so don’t take this exercise lightly. Take your time. Use the exercise as a way to open a discussion about values. Find out what you and your team believe in. Set these values and keep them in place. Write them down and share these with your team and with the world. By sharing your core values, you hold yourself more accountable to them. You also send a strong message to the rest of the world about what type of organization you are and what you believe in. Other organizations and people may decide to align or not to align themselves with you because of your core values. This is good. Chances are, you’ll be happier and more profitable if you work with other organizations and people who share similar core values.

During your brainstorming session, list keywords. Don’t edit. Allow things to take their course. Some examples of keywords might be:
Ability · Achievement · Adventure · Ambition · Altruism · Awareness · Balance · Caring · Charity · Citizenship · Collaboration · Commitment · Community · Compassion · Consideration · Cooperation · Courage · Courtesy · Creativity · Democracy · Dignity · Diplomacy · Discipline · Diversity · Education · Efficiency · Energy · Equality · Excellence · Excitement · Fairness · Family · Freedom · Fun · Goodness · Gratefulness · Growth · Happiness · Harmony · Helping · Honor · Hope · Humility · Humor · Imagination · Individuality · Innovation · Integrity · Intelligence · Joy · Justice · Kindness · Knowledge · Leadership · Learning · Loyalty · Meaning · Mindfulness · Moderation · Modesty · Nurture · Openness · Organization · Passion · Patience · Peace · Planning · Principles · Productivity · Purpose · Quality · Reliability · Respectfulness · Responsibility · Security · Sensitivity · Service · Sharing · Simplicity · Stability · Tolerance · Transparency · Trust · Truthfulness · Understanding · Unity · Variety · Vision · Wisdom
After you have a list of keywords, create your core values statement using the themes from your brainstorming session. There are no rules: while above, Steve Jobs summed up Apple’s core values in one sentence, Zappos has ten core values:
Deliver WOW Through Service
Embrace and Drive Change
Create Fun and A Little Weirdness
Be Adventurous, Creative, and Open-Minded
Pursue Growth and Learning
Build Open and Honest Relationships With Communication
Build a Positive Team and Family Spirit
Do More With Less
Be Passionate and Determined
Be Humble
To see how Zappos’ employees embrace these core values, watch the video they created and posted on their website.
Dog food is yummy
Although I find merit in every keyword listed, I’ve distilled my core values to their simplest form:
Make awesomeness. Do good.
How do you make awesomeness and do good? You need ambition, balance, collaboration, commitment, fun, and you need every keyword listed to support these actions. Again, there are no rules: your core values can be one sentence or a bulleted list. What matters is being true to yourself and creating core values that others can understand. Before I start any project I ask myself: is there a way to make awesomeness and to do good? If the answer is “yes,” I embrace the endeavor because it aligns with my core values. If the answer is “no,” I move on to a project that supports my core values.
Unleash your powers
Although every organization will craft different core values, I imagine that you want to be a superhero and that you will define “doing good” (or something similar) as one of your core values. Whether you work by yourself or with a team, you can use the web as a tool to help do good. It can be as simple as giving a free hug, or something a little more complex to help others and help your organization meet the bottom line. Some interesting initiatives that use the web to do good are:
Yahoo!: How Good Grows
Desigual: Happy Hunters
Edge Shave Gel: Anti-irritation campaign
Knowing your underlying desire to return to your Underoos-and-cape-sporting childhood and knowing that you don’t always have the opportunity to develop an entire initiative to “do good,” remember that as writers, designers, and developers, we can perform superhero acts on a daily basis by making content, design, and development accessible to the greatest number of people. By considering other people’s needs, we are intentionally performing acts of kindness—we’re doing good. There are many ways to write, design, and develop websites—many of which will be discussed in other 24ways.org articles. As we make content, design, and development decisions—as we develop campaigns and initiatives—we need to keep our core values in mind. It’s easy to make a positive difference in the world. Just be the superhero you’ve always wanted to be. Go forth and make awesomeness.
If you would like to do good today, support The United Nations Children’s Fund, an organization that works for children’s rights, their survival, development and protection, by purchasing this year’s 24 ways Annual 2010 created by Five Simple Steps. All proceeds go to UNICEF. |

Good Ideas Grow on Paper |
Great designers have one thing in common: their design process is centred on ideas; ideas that are more often than not developed on paper. Though it’s often tempting to take the path of least resistance, turning to the computer in the headlong rush to complete a project (often in the face of formidable client pressure), resist the urge and – for a truly great idea – start first on paper.
The path of least resistance is often characterised by cliché and overused techniques – one per cent noise, border-radius, text-shadow – the usual suspects – techniques that are ten-a-penny at the gallery sites. Whilst all are useful, and technique and craft are important, great design isn’t about technique alone – it’s about technique in the service of good ideas.
But how do we generate those ideas?
Inspiration can certainly come to you out of the blue. When working as a designer in a role which often consists of incubating good ideas, however, idly waiting for the time-honoured lightbulb to appear above your head just isn’t good enough. We need to establish an environment where we tip the odds of getting good ideas in our favour.
So, when faced with the blank canvas, what do we do to unlock the proverbial tidal wave of creativity? Fear not. We’re about to share with you a couple of stalwart techniques that will stand you in good stead when you need that good idea, in the face of the pressure of yet another looming deadline.
Get the process right
Where do ideas come from? In many cases they come from anywhere but the screen. Hence, our first commandment is to close the lid of your computer and, for a change, work on paper. It might seem strange, it might also seem like a distraction, but – trust us – the time invested here will more than pay off.
Idea generation should be a process of rapid iteration, sketching and thinking aloud, all processes best undertaken in more fast paced, analogue media. Our tool of choice is the Sharpie and Flip Chart Combo©, intentionally low resolution to encourage lo-fi idea generation. In short, your tools should be designed not to be precious, but to quickly process your thoughts. Ideas can be expressed with a thick line marker or by drawing with a stick in the sand; it’s the ideas that matter, not the medium.
Input > Synthesise > Output
Ideas don’t materialise in a vacuum. Without constant input, the outputs will inevitably remain the same. As such, it’s essential to maintain an inquisitive mind, ensuring a steady flow of new triggers and stimuli that enable your thinking to evolve.
What every designer brings to the table is their prior experience and unique knowledge. It should come as no surprise to discover that a tried and tested method of increasing that knowledge is, believe it or not, to read – often and widely. The best and most nuanced ideas come after many years of priming the brain with an array of diverse material, a point made recently in Jessica Hische’s aptly named Why You Should Know Your Shit.
One of the best ways of synthesising the knowledge you accumulate is to write. The act of writing facilitates your thinking and stores the pieces of the jigsaw you’ll one day return to. You don’t have to write a book or a well-articulated article; a scribbled note in the margin will suffice in facilitating the process of digestion.
As with writing, we implore you to make sketching an essential part of your digestion process. More immediate than writing, sketching has the power to put yet unformed ideas down on paper, giving you an insight into the fantastic conceptions you’re more often than not still incubating.
Our second commandment is a practical one: always carry a sketchbook and a pen. Although it seems that the very best ideas are scribbled on the back of a beer mat or a wine-stained napkin, always carrying your ‘thinking utensils’ should be as natural as not leaving the house without your phone, wallet, keys or pants.
Further, the more you use your sketchbook, the less precious you’ll find yourself becoming. Sketching isn’t about being an excellent draughtsman, it’s about synthesising and processing your thoughts and ideas, as Jason Santa Maria summarises nicely in his article Pretty Sketchy:
Sketchbooks are not about being a good artist, they’re about being a good thinker.
Jason Santa Maria
The sketchbook and pen should become your trusted tools in your task to constantly survey the world around you. As Paul Smith says, You Can Find Inspiration in Anything; close the lid, look beyond the computer; there’s a whole world of inspiration out there.
Learn to love old dusty buildings
So, how do you learn? How do you push beyond the predictable world pre-filtered by Mr Google? The answer lies in establishing a habit of exploring the wonderful worlds of museums and libraries, dusty old buildings that repay repeated visits.
Once the primary repositories of thought and endless sources of inspiration, these institutions are now often passed over for the quick fix of a Google search or Wikipedia by you, the designer, chained to a desk and manacled to a MacBook. Whilst others might frown, we urge you to get away from your desk and take an eye-opening stroll through the knowledge-filled corridors of yore (and don’t forget to bring your sketchbook).
Here you’ll find ideas aplenty, ideas that will set you apart from your peers, who remain ever-reliant on the same old digital sources.
The idea generation toolbox
Now that we’ve established the importance of getting the process and the context right, it’s time to meet the idea generation toolbox: a series of tools and techniques that can be applied singularly or in combination to solve the perennial problem of the blank canvas.
The clean sheet of paper, numbing in its emptiness, can prove an insurmountable barrier to many a project, but the route beyond it involves just a few, well-considered steps. The route to a good idea lies in widening your pool of inspiration at the project outset. Let go and generate ideas quickly; it’s critical to diverge before you converge – but how do we do this and what exactly do we mean by this?
The temptation is to pull something out of your well-worn box of tricks, something that you know from experience will do the job. We urge you, however, not to fall prey to this desire. You can do better; better still, a few of you putting your minds together can do a lot better. By avoiding the path of least resistance, you can create something extraordinary.
Culturally, we value logical, linear thinking. Since the days of Plato and Aristotle, critical thinking, deduction and the pursuit of truth have been rewarded. To generate creative ideas, however, we need to start thinking sideways, making connections that don’t necessarily follow logically. Lateral thinking, a phrase coined by Edward de Bono in 1967, aptly describes this very process:
With logic you start out with certain ingredients, just as in playing chess you start out with given pieces – lateral thinking is concerned not with playing with the existing pieces but with seeking to change those very pieces.
Edward de Bono
One of the easiest ways to start thinking laterally is to start with a mind map, a perfect tool for widening the scope of a project beyond the predictable and an ideal one for getting the context right for discovery.
Making connections
Mind maps can be used to generate, visualise and structure ideas. Arranged intuitively and classified around groupings, mind maps allow chance connections to be drawn across related groups of information, and are perfect for exposing alogical associations and unexpected relationships.
Get a number of people together in a room, equipped with the Sharpie and Flip Chart Combo©. Give yourself a limited amount of time – half an hour should prove more than enough – and you’ll be surprised at the results a few well-chosen people can generate in a very short space of time. The key is to work fast, diverge and not inhibit thinking.
We’ve been embracing Tony Buzan’s methods in our teaching for over a decade. His ideas on the power of radiant thinking and how this can be applied to mind maps, uncover the real power which lies in the human brain’s ability to spot connections across a mapped out body of diverse knowledge.
Frank Chimero wrote about this recently in How to Have an Idea, which beautifully illustrates Mr Buzan’s theories, articulating the importance of the brain’s ability to make abstract connections, finding unexpected pairings when a concept is mapped out on paper.
Once a topic is surveyed and a rich set of stimuli articulated, the next stage is to draw connections, pulling from opposite sides of the mind map. It’s at this point, when defining alogical connections, that the truly interesting and unexpected ideas are often uncovered.
The curve ball
If you’ve followed our instructions so far, all being well, you should have a number of ideas. Good news: we have one last technique to throw into the mix. We like to call it ‘the curve ball’, that last minute ‘something’ that forces you to rethink and encourages you to address a problem from a different direction.
There are a number of ways of throwing in a curve ball – a short, sharp, unexpected impetus – but we have a firm favourite we think you’ll appreciate. Brian Eno and Peter Schmidt’s Oblique Strategies – subtitled ‘Over One Hundred Worthwhile Dilemmas’ – are the perfect creative tool for throwing in a spot of unpredictability. As Eno and Schmidt put it:
The Oblique Strategies can be used as a pack (a set of possibilities being continuously reviewed in the mind) or by drawing a single card from the shuffled pack when a dilemma occurs in a working situation. In this case the card is trusted even if its appropriateness is quite unclear. They are not final, as new ideas will present themselves, and others will become self-evident.
Brian Eno and Peter Schmidt
Simply pick a card and apply the strategy to the problem at hand. The key here, as with de Bono’s techniques, is to embrace randomness and provocation to inspire lateral creative approaches.
To assist this process, you might wish to consult one of the many virtual decks of Oblique Strategies online.
Wrapping up
To summarise, it’s tempting to see the route to the fastest satisfactory conclusion in a computer when, in reality, that’s the last place you should start. The tools we’ve introduced, far from time-consuming, are hyper-efficient, always at hand and, if you factor them into your workflow, the key to unlocking the ideas that set the great designers apart.
We wish you well on your quest in search of the perfect idea, now armed with the knowledge that the quest begins on paper. |
