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
elements inside the #container, no matter how deeply nested they are. You can view the result in Demo Two. As you can see, the golden rectangles alternate between landscape and portrait orientation.
Demo Three).
CSS3 specification indicates that a percentage can be used to set the border-radius property, but using percentages does not achieve consistent results in browsers today. Luckily, if you specify a border-radius in pixels using a value that is greater than the width and height of the element, then the resulting curve will use the shorter length side as its radius. This produces exactly the effect that we want, so we’ll use an arbitrarily high value of 10,000 pixels for each border-radius:
.cycle {
border-radius: 0px;
border-bottom-left-radius: 10000px;
}
.cycle > div {
border-radius: 0px;
border-bottom-right-radius: 10000px;
}
.cycle > div > div {
border-radius: 0px;
border-top-right-radius: 10000px;
}
.cycle > div > div > div {
border-radius: 0px;
border-top-left-radius: 10000px;
}
Note that the specification for the border-radius property is still in flux, so it is advisable to use vendor-specific prefixes. I have omitted them from the example above for the sake of clarity, but if you view source on Demo Four then you’ll see that the actual styles are not quite as brief.
Filling the available space
We have created an approximation of the Golden Spiral using only HTML and CSS. Neat! It’s a shame that it occupies just a fraction of the available space. As a finishing touch, let’s make the golden spiral expand or contract to use the full space available to it.
Ideally, the outermost container should use the full available width or height that could accomodate a rectangle of golden proportions. This behaviour is available for background images using the “ background-size: contain; property, but I know of no way to make block level HTML elements behave in this fashion (if I’m missing something, please enlighten me). Where CSS fails to deliver, JavaScript can usually provide a workaround. This snippet requires jQuery:
$(document).ready(function() {
var phi = (1 + Math.sqrt(5))/2;
$(window).resize(function() {
var goldenWidth = windowWidth = $(this).width(),
goldenHeight = windowHeight = $(this).height();
if (windowWidth/windowHeight > phi) {
// panoramic viewport – use full height
goldenWidth = windowHeight * phi;
} else {
// portrait viewport – use full width
goldenHeight = windowWidth / phi;
};
$(""#container > div.cycle"")
.width(goldenWidth)
.height(goldenHeight);
}).resize();
});
You can view the result by visiting Demo Five.
Is it just me, or can you see an elephant in there?
You can probably think of many ways to enhance this further, but for this study we’ll leave it there. It has been a good excuse to play with proportions, positioning and the immediate child selector, as well as new CSS3 features such as border-radius and RGBA colours. If you are not already designing with golden proportions, then perhaps this will inspire you to begin.",2010,Drew Neil,drewneil,2010-12-07T00:00:00+00:00,https://24ways.org/2010/golden-spirals/,design
218,Put Yourself in a Corner,"Some backstory, and a shameful confession
For the first couple years of high school I was one of those jerks who made only the minimal required effort in school. Strangely enough, how badly I behaved in a class was always in direct proportion to how skilled I was in the subject matter. In the subjects where I was confident that I could pass without trying too hard, I would give myself added freedom to goof off in class.
Because I was a closeted lit-nerd, I was most skilled in English class. I’d devour and annotate required reading over the weekend, I knew my biblical and mythological allusions up and down, and I could give you a postmodern interpretation of a text like nobody’s business. But in class, I’d sit in the back and gossip with my friends, nap, or scribble patterns in the margins of my textbooks. I was nonchalant during discussion, I pretended not to listen during lectures. I secretly knew my stuff, so I did well enough on tests, quizzes, and essays. But I acted like an ass, and wasn’t getting the most I could out of my education.
The day of humiliation, but also epiphany
One day in Ms. Kaney’s AP English Lit class, I was sitting in the back doodling. An earbud was dangling under my sweater hood, attached to the CD player (remember those?) sitting in my desk. Because of this auditory distraction, the first time Ms. Kaney called my name, I barely noticed. I definitely heard her the second time, when she didn’t call my name so much as roar it. I can still remember her five feet frame stomping across the room and grabbing an empty desk. It screamed across the worn tile as she slammed it next to hers. She said, “This is where you sit now.” My face gets hot just thinking about it.
I gathered my things, including the CD player (which was now impossible to conceal), and made my way up to the newly appointed Seat of Shame. There I sat, with my back to the class, eye-to-eye with Ms. Kaney. From my new vantage point I couldn’t see my friends, or the clock, or the window. All I saw were Ms. Kaney’s eyes, peering at me over her reading glasses while I worked. In addition to this punishment, I was told that from now on, not only would I participate in class discussions, but I would serve detention with her once a week until an undetermined point in the future.
During these detentions, Ms. Kaney would give me new books to read, outside the curriculum, and added on to my normal homework. They ranged from classics to modern novels, and she read over my notes on each book. We’d discuss them at length after class, and I grew to value not only our private discussions, but the ones in class as well. After a few weeks, there wasn’t even a question of this being punishment. It was heaven, and I was more productive than ever.
To the point
Please excuse this sentimental story. It’s not just about honoring a teacher who cared enough to change my life, it’s really about sharing a lesson. The most valuable education Ms. Kaney gave me had nothing to do with literature. She taught me that I (and perhaps other people who share my special brand of crazy) need to be put in a corner to flourish. When we have physical and mental constraints applied, we accomplish our best work.
For those of you still reading, now seems like a good time to insert a pre-emptive word of mediation. Many of you, maybe all of you, are self-disciplined enough that you don’t require the rigorous restrictions I use to maximize productivity. Also, I know many people who operate best in a stimulating and open environment. I would advise everyone to seek and execute techniques that work best for them. But, for those of you who share my inclination towards daydreams and digressions, perhaps you’ll find something useful in the advice to follow.
In which I pretend to be Special Agent Olivia Dunham
Now that I’m an adult, and no longer have Ms. Kaney to reign me in, I have to find ways to put myself in the corner. By rejecting distraction and shaping an environment designed for intense focus, I’m able to achieve improved productivity.
Lately I’ve been obsessed with the TV show Fringe, a sci-fi series about an FBI agent and her team of genius scientists who save the world (no, YOU’RE a nerd). There’s a scene in the show where the primary character has to delve into her subconscious to do extraordinary things, and she accomplishes this by immersing herself in a sensory deprivation tank. The premise is this: when enclosed in a space devoid of sound, smell, or light, she will enter a new plane of consciousness wherein she can tap into new levels of perception.
This might sound a little nuts, but to me this premise has some real-world application. When I am isolated from distraction, and limited to only the task at hand, I’m able to be productive on a whole new level. Since I can’t actually work in an airtight iron enclosure devoid of input, I find practical ways to create an interruption-free environment.
Since I work from home, many of my methods for coping with distractions wouldn’t be necessary for my office-bound counterpart. However for some of you 9-to-5-ers, the principles will still apply.
Consider your visual input
First, I have to limit my scope to the world I can (and need to) affect. In the largest sense, this means closing my curtains to the chaotic scene of traffic, birds, the post office, a convenience store, and generally lovely weather that waits outside my window. When the curtains are drawn and I’m no longer surrounded by this view, my sphere is reduced to my desk, my TV, and my cat. Sometimes this step alone is enough to allow me to focus.
But, my visual input can be whittled down further still. For example, the desk where I usually keep my laptop is littered with twelve owl figurines, a globe, four books, a three-pound weight, and various nerdy paraphernalia (hard drives, Wacom tablets, unnecessary bluetooth accessories, and so on). It’s not so much a desk as a dumping ground for wacky flea market finds and impulse technology buys. Therefore, in addition to this Official Desk, I have an adult version of Ms. Kaney’s Seat of Shame. It’s a rusty old student’s desk I picked up at the Salvation Army, almost an exact replica of the model Ms. Kaney dragged across the classroom all those years ago. This tiny reproduction Seat of Shame is literally in a corner, where my only view is a blank wall. When I truly need to focus, this is where I take refuge, with only a notebook and a pencil (and occasionally an iPad).
Find out what works for your ears
Even from my limited sample size of two people, I know there are lots of different ways to cope with auditory distraction. I prefer silence when focused on independent work, and usually employ some form of a white noise generator. I’ve yet to opt for the fancy ‘real’ white noise machines; instead, I use a desktop fan or our allergy filter machine. This is usually sufficient to block out the sounds of the dishwasher and the cat, which allows me to think only about the task of hand.
My boyfriend, the other half of my extensive survey, swears by another method. He calls it The Wall of Sound, and it’s basically an intense blast of raucous music streamed directly into his head. The outcome of his technique is really the same as mine; he’s blocking out unexpected auditory input. If you can handle the grating sounds of noisy music while working, I suggest you give The Wall of Sound a try.
Don’t count the minutes
When I sat in the original Seat of Shame in lit class, I could no longer see the big classroom clock slowly ticking away the seconds until lunch. Without the marker of time, the class period often flew by. The same is true now when I work; the less aware of time I am, the less it feels like time is passing too quickly or slowly, and the more I can focus on the task (not how long it takes).
Nowadays, to assist in my effort to forget the passing of time, I sometimes put a sticky note over the clock on my monitor. If I’m writing, I’ll use an app like WriteRoom, which blocks out everything but a simple text editor.
There are situations when it’s not advisable to completely lose track of time. If I’m working on a project with an hourly rate and a tight scope, or if I need to be on time to a meeting or call, I don’t want to lose myself in the expanse of the day. In these cases, I’ll set an alarm that lets me know it’s time to reign myself back in (or on some days, take a shower).
Put yourself in a mental corner, too
When Ms. Kaney took action and forced me to step up my game, she had the insight to not just change things physically, but to challenge me mentally as well. She assigned me reading material outside the normal coursework, then upped the pressure by requiring detailed reports of the material. While this additional stress was sometimes uncomfortable, it pushed me to work harder than I would have had there been less of a demand. Just as there can be freedom in the limitations of a distraction-free environment, I’d argue there is liberty in added mental constraints as well.
Deadlines as a constraint
Much has been written about the role of deadlines in the creative process, and they seem to serve different functions in different cases. I find that deadlines usually act as an important constraint and, without them, it would be nearly impossible for me to ever consider a project finished. There are usually limitless ways to improve upon the work I do and, if there’s no imperative for me to be done at a certain point, I will revise ad infinitum. (Hence, the personal site redesign that will never end – Coming Soon, Forever!). But if I have a clear deadline in mind, there’s a point when the obsessive tweaking has to stop. I reach a stage where I have to gather up the nerve to launch the thing.
Putting the pro in procrastination
Sometimes I’ve found that my tendency to procrastinate can help my productivity. (Ducks, as half the internet throws things at her.) I understand the reasons why procrastination can be harmful, and why it’s usually a good idea to work diligently and evenly towards a goal. I try to divide my projects up in a practical way, and sometimes I even pull it off. But for those tasks where you work aimlessly and no focus comes, or you find that every other to-do item is more appealing, sometimes you’re forced to bring it together at the last moment. And sometimes, this environment of stress is a formula for magic. Often when I’m down to the wire and have no choice but to produce, my mind shifts towards a new level of clarity. There’s no time to endlessly browse for inspiration, or experiment with convoluted solutions that lead nowhere.
Obviously a life lived perpetually on the edge of a deadline would be a rather stressful one, so it’s not a state of being I’d advocate for everyone, all the time. But every now and then, the work done when I’m down to the wire is my best.
Keep one toe outside your comfort zone
When I’m choosing new projects to take on, I often seek out work that involves an element of challenge. Whether it’s a design problem that will require some creative thinking, or a coding project that lends itself to using new technology like HTML5, I find a manageable level of difficulty to be an added bonus. The tension that comes from learning a new skill or rethinking an old standby is a useful constraint, as it keeps the work interesting, and ensures that I continue learning.
There you have it
Well, I think I’ve spilled most of my crazy secrets for forcing my easily distracted brain to focus. As with everything we web workers do, there are an infinite number of ways to encourage productivity. I hope you’ve found a few of these to be helpful, and please share your personal techniques in the comments.

225,Good Ideas Grow on Paper,"Great designers have one thing in common: their design process is centred on ideas; ideas that are more often than not developed on paper. Though it’s often tempting to take the path of least resistance, turning to the computer in the headlong rush to complete a project (often in the face of formidable client pressure), resist the urge and – for a truly great idea – start first on paper.
The path of least resistance is often characterised by cliché and overused techniques – one per cent noise, border-radius, text-shadow – the usual suspects – techniques that are ten-a-penny at the gallery sites. Whilst all are useful, and technique and craft are important, great design isn’t about technique alone – it’s about technique in the service of good ideas.
But how do we generate those ideas?
Inspiration can certainly come to you out of the blue. When working as a designer in a role which often consists of incubating good ideas, however, idly waiting for the time-honoured lightbulb to appear above your head just isn’t good enough. We need to establish an environment where we tip the odds of getting good ideas in our favour.
So, when faced with the blank canvas, what do we do to unlock the proverbial tidal wave of creativity? Fear not. We’re about to share with you a couple of stalwart techniques that will stand you in good stead when you need that good idea, in the face of the pressure of yet another looming deadline.
Get the process right
Where do ideas come from? In many cases they come from anywhere but the screen. Hence, our first commandment is to close the lid of your computer and, for a change, work on paper. It might seem strange, it might also seem like a distraction, but – trust us – the time invested here will more than pay off.
Idea generation should be a process of rapid iteration, sketching and thinking aloud, all processes best undertaken in more fast paced, analogue media. Our tool of choice is the Sharpie and Flip Chart Combo©, intentionally low resolution to encourage lo-fi idea generation. In short, your tools should be designed not to be precious, but to quickly process your thoughts. Ideas can be expressed with a thick line marker or by drawing with a stick in the sand; it’s the ideas that matter, not the medium.
Input > Synthesise > Output
Ideas don’t materialise in a vacuum. Without constant input, the outputs will inevitably remain the same. As such, it’s essential to maintain an inquisitive mind, ensuring a steady flow of new triggers and stimuli that enable your thinking to evolve.
What every designer brings to the table is their prior experience and unique knowledge. It should come as no surprise to discover that a tried and tested method of increasing that knowledge is, believe it or not, to read – often and widely. The best and most nuanced ideas come after many years of priming the brain with an array of diverse material, a point made recently in Jessica Hische’s aptly named Why You Should Know Your Shit.
One of the best ways of synthesising the knowledge you accumulate is to write. The act of writing facilitates your thinking and stores the pieces of the jigsaw you’ll one day return to. You don’t have to write a book or a well-articulated article; a scribbled note in the margin will suffice in facilitating the process of digestion.
As with writing, we implore you to make sketching an essential part of your digestion process. More immediate than writing, sketching has the power to put yet unformed ideas down on paper, giving you an insight into the fantastic conceptions you’re more often than not still incubating.
Our second commandment is a practical one: always carry a sketchbook and a pen. Although it seems that the very best ideas are scribbled on the back of a beer mat or a wine-stained napkin, always carrying your ‘thinking utensils’ should be as natural as not leaving the house without your phone, wallet, keys or pants.
Further, the more you use your sketchbook, the less precious you’ll find yourself becoming. Sketching isn’t about being an excellent draughtsman, it’s about synthesising and processing your thoughts and ideas, as Jason Santa Maria summarises nicely in his article Pretty Sketchy:
Sketchbooks are not about being a good artist, they’re about being a good thinker.
Jason Santa Maria
The sketchbook and pen should become your trusted tools in your task to constantly survey the world around you. As Paul Smith says, You Can Find Inspiration in Anything; close the lid, look beyond the computer; there’s a whole world of inspiration out there.
Learn to love old dusty buildings
So, how do you learn? How do you push beyond the predictable world pre-filtered by Mr Google? The answer lies in establishing a habit of exploring the wonderful worlds of museums and libraries, dusty old buildings that repay repeated visits.
Once the primary repositories of thought and endless sources of inspiration, these institutions are now often passed over for the quick fix of a Google search or Wikipedia by you, the designer, chained to a desk and manacled to a MacBook. Whilst others might frown, we urge you to get away from your desk and take an eye-opening stroll through the knowledge-filled corridors of yore (and don’t forget to bring your sketchbook).
Here you’ll find ideas aplenty, ideas that will set you apart from your peers, who remain ever-reliant on the same old digital sources.
The idea generation toolbox
Now that we’ve established the importance of getting the process and the context right, it’s time to meet the idea generation toolbox: a series of tools and techniques that can be applied singularly or in combination to solve the perennial problem of the blank canvas.
The clean sheet of paper, numbing in its emptiness, can prove an insurmountable barrier to many a project, but the route beyond it involves just a few, well-considered steps. The route to a good idea lies in widening your pool of inspiration at the project outset. Let go and generate ideas quickly; it’s critical to diverge before you converge – but how do we do this and what exactly do we mean by this?
The temptation is to pull something out of your well-worn box of tricks, something that you know from experience will do the job. We urge you, however, not to fall prey to this desire. You can do better; better still, a few of you putting your minds together can do a lot better. By avoiding the path of least resistance, you can create something extraordinary.
Culturally, we value logical, linear thinking. Since the days of Plato and Aristotle, critical thinking, deduction and the pursuit of truth have been rewarded. To generate creative ideas, however, we need to start thinking sideways, making connections that don’t necessarily follow logically. Lateral thinking, a phrase coined by Edward de Bono in 1967, aptly describes this very process:
With logic you start out with certain ingredients, just as in playing chess you start out with given pieces – lateral thinking is concerned not with playing with the existing pieces but with seeking to change those very pieces.
Edward de Bono
One of the easiest ways to start thinking laterally is to start with a mind map, a perfect tool for widening the scope of a project beyond the predictable and an ideal one for getting the context right for discovery.
Making connections
Mind maps can be used to generate, visualise and structure ideas. Arranged intuitively and classified around groupings, mind maps allow chance connections to be drawn across related groups of information, and are perfect for exposing alogical associations and unexpected relationships.
Get a number of people together in a room, equipped with the Sharpie and Flip Chart Combo©. Give yourself a limited amount of time – half an hour should prove more than enough – and you’ll be surprised at the results a few well-chosen people can generate in a very short space of time. The key is to work fast, diverge and not inhibit thinking.
We’ve been embracing Tony Buzan’s methods in our teaching for over a decade. His ideas on the power of radiant thinking and how this can be applied to mind maps, uncover the real power which lies in the human brain’s ability to spot connections across a mapped out body of diverse knowledge.
Frank Chimero wrote about this recently in How to Have an Idea, which beautifully illustrates Mr Buzan’s theories, articulating the importance of the brain’s ability to make abstract connections, finding unexpected pairings when a concept is mapped out on paper.
Once a topic is surveyed and a rich set of stimuli articulated, the next stage is to draw connections, pulling from opposite sides of the mind map. It’s at this point, when defining alogical connections, that the truly interesting and unexpected ideas are often uncovered.
The curve ball
If you’ve followed our instructions so far, all being well, you should have a number of ideas. Good news: we have one last technique to throw into the mix. We like to call it ‘the curve ball’, that last minute ‘something’ that forces you to rethink and encourages you to address a problem from a different direction.
There are a number of ways of throwing in a curve ball – a short, sharp, unexpected impetus – but we have a firm favourite we think you’ll appreciate. Brian Eno and Peter Schmidt’s Oblique Strategies – subtitled ‘Over One Hundred Worthwhile Dilemmas’ – are the perfect creative tool for throwing in a spot of unpredictability. As Eno and Schmidt put it:
The Oblique Strategies can be used as a pack (a set of possibilities being continuously reviewed in the mind) or by drawing a single card from the shuffled pack when a dilemma occurs in a working situation. In this case the card is trusted even if its appropriateness is quite unclear. They are not final, as new ideas will present themselves, and others will become self-evident.
Brian Eno and Peter Schmidt
Simply pick a card and apply the strategy to the problem at hand. The key here, as with de Bono’s techniques, is to embrace randomness and provocation to inspire lateral creative approaches.
To assist this process, you might wish to consult one of the many virtual decks of Oblique Strategies online.
Wrapping up
To summarise, it’s tempting to see the route to the fastest satisfactory conclusion in a computer when, in reality, that’s the last place you should start. The tools we’ve introduced, far from time-consuming, are hyper-efficient, always at hand and, if you factor them into your workflow, the key to unlocking the ideas that set the great designers apart.
We wish you well on your quest in search of the perfect idea, now armed with the knowledge that the quest begins on paper.",2010,The Standardistas,thestandardistas,2010-12-13T00:00:00+00:00,https://24ways.org/2010/good-ideas-grow-on-paper/,process
226,Documentation-Driven Design for APIs,"Documentation is like gift wrapping. It seems like superfluous fluff, but your family tends to be rather disappointed when their presents arrive in supermarket carrier bags, so you have to feign some sort of attempt at making your gift look enticing. Documentation doesn’t have to be all hard work and sellotaping yourself to a table – you can make it useful and relevant.
Documentation gets a pretty rough deal. It tends to get left until the end of a project, when some poor developer is assigned the ‘document project’ ticket and wades through each feature of Whizzy New API 3.0 and needs to recall exactly what each method is meant to do. That’s assuming any time is left for documentation at all. The more common outcome resembles last minute homework scribbled on a post-it note, where just the bare bones of what’s available are put out for your users, and you hope that you’ll spot the inconsistencies and mistakes before they do.
Wouldn’t it be nicer for everyone if you could make documentation not only outstanding for your users, but also a valuable tool for your development team – so much so that you couldn’t imagine writing a line of code before you’d documented it?
Documentation needs to have three main features:
It should have total coverage and document all the features of your project. Private methods should be documented for your developers, and public features need to be available to your users.
It should be consistent – a user should know what to expect from your documentation, and terminology should be accurate to your language.
It should be current – and that means staying accurate as new versions of your code base are released.
But you can also get these bonuses:
Act as a suggested specification – a guide that will aid a developer in making something consistent and usable.
It can test your API quality.
It can enhance the communication skills within your development team.
So how do we get our documentation to be rich and full of features, instead of a little worn out like Boxing Day leftovers?
Write your documentation first
When I say first, I mean first. Not after you’ve started writing the code. Not even after you’ve started writing your unit tests. First. You may or may not have been provided with a decent specification, but the first job should be to turn your requirements for a feature into documentation.
It works best when it takes the form of in-code comments. It works even better when your in-code comments take a standard documentation format that you can later use to generate published documentation for your users. This has the benefit of immediately making your docs as version controlled as your code-base, and it saves having to rewrite, copy or otherwise harass your docs into something legible later on.
Almost all languages have a self-documentation format these days. My choice of format for JavaScript is JSDocToolkit, and the sort of things I look for are the ability to specify private and public methods, full options object statements (opts as Opts only is a no-no), and the ability to include good examples.
So, our example for today will be a new festive feature for a JavaScript API. We’ve been asked to specify a sled for Santa to get around the world to give out toys:
Santa needs to be able to travel around the world in one night to deliver toys to children, and he’ll need some reindeer to pull his sled.
As documentation, it would look like:
/**
@name Sled
@extends Vehicle
@constructor
@description Create a new sled to send Santa around the world to deliver toys to good kids.
@param {Object} [opts] Options
@param {number} [opts.capacity='50'] Set the capacity of the sled
@param {string} [opts.pilot='santa'] The pilot of the sled.
@example
// Create a sled and specify some reindeer.
new Sled().reindeer(['Dasher', 'Dancer', 'Prancer', 'Vixen', 'Comet', 'Cupid']);
*/
By breaking it down as documentation, you can, for example, hand this over to another developer without the need to explain the feature in much depth, and they’ll develop something that has to match this piece of documentation. It specifies everything that is important to this feature – its default values and types, and where it inherits other features from.
We know that we need to specify some way of setting reindeer to pull the sled and also some toys to give, and so we can quickly specify extra methods for the sled:
/*
@name vehicle.Sled#reindeer
@function
@description Set the reindeer that will pull Santa's sled.
@param {string[]} reindeer A list of the reindeer.
@example
// specifying some reindeer
Sled().reindeer(['Dasher', 'Dancer', 'Rudolph', 'Vixen']);
*/
/*
@name vehicle.Sled#toys
@function
@description Add a list of toys and recipients to the Sled.
@param {Object[]} toys A list of toys and who will receive them.
@example
// Adding toys to the sled
Sled().toys([
{name:'Brian', toy:'Fire Engine'},
{name:'Drew', toy:'Roller-skates'},
{name:'Anna', toy:'Play-doh'},
...
]);
*/
Job done! You’ve got a specification to share with your team and something useful for your users in the form of full examples, and you didn’t even have to open another text editor.
Use your documentation to share knowledge
Documentation isn’t just for users. It’s also used by internal developers to explain what they’ve written and how it works. This is especially valuable where the team is large or the code-base sprawling.
So, returning to our example, the next step would be to share with the rest of the team (or at least a selection of the team if yours is large) what the documentation looks like. This is useful for two main reasons:
They can see if they understand what the documentation says the feature will do. It’s best if they haven’t seen the requirement before. If your fellow developers can’t work out what ‘MagicMethodX’ is going to return from the docs, neither can your users.
They can check that the feature accomplishes everything that they expect to, and that it’s consistent with the rest of the functionality.
On previous projects, we’ve taken to referring to this stage of the development process as the ‘bun fight’. It’s a chance for everyone to have an honest say and throw a few pies without actually causing anyone to have to rewrite any code. If you can identify at this stage that a feature is over-complicated, lacking or just plain useless, you’ll all be much happier to throw out a few lines of documentation than you may have been to throw out a partial, or even complete, piece of functionality.
Documentation has your back
The final benefit to working in this way is that your documentation not only remains accurate, it’s always as accurate as your latest release. It can’t fall behind. You can increase the likelihood that your docs will remain up to date by unit testing your examples.
Returning to the previous example, we can add a QUnit unit test to the expected output with ease during the build process – we know exactly how the code will look and, with the @example tag, we can identify easily where to find the bits that need testing. If it’s tested it’ll definitely work as you expect it to when a user copy and pastes it. You’re ensuring quality from idea to implementation.
As an extra bauble, the best thing about a system like JSDocToolkit is that it’ll take your inline comments and turn them into beautiful sites, as good systems will allow for customised output templates. You’ll be producing full-featured sites for your projects and plugins with almost no extra effort, but all the benefits.",2010,Frances Berriman,francesberriman,2010-12-11T00:00:00+00:00,https://24ways.org/2010/documentation-driven-design-for-apis/,process
230,The Articulate Web Designer of Tomorrow,"You could say that we design to communicate, and that we seek emotive responses. It sounds straightforward, and it can be, but leaving it to chance isn’t wise. Many wander into web design without formal training, and whilst that certainly isn’t essential, we owe it to ourselves to draw on wider influences, learn from the past, and think smarter.
What knowledge can we ourselves explore in order to become better designers? In addition, how can we take this knowledge, investigate it through our unique discipline, and in turn speak more eloquently about what we do on the web? Below, I outline a number of things that I personally believe all designers should be using and exploring collectively.
Taking stock
Where we’re at is good. Finding clarity through web standards, we’ve ended up quite modernist in our approach, pursuing function, elegance and reduction. However, we’re not great at articulating our own design processes and principles to outsiders. Equally, we rely heavily on our instincts when deciding if something is or isn’t good. That’s fine, but we can better understand why things are the way they are by looking a little deeper, thereby helping us articulate what goes on in our design brains to our peers, our clients and to normal humans.
As designers we use ideas, concepts, text and images. We apply our ideas and experience, imposing order and structure to content, hoping to ease the communication of an idea to the largest possible audience or to a specific audience. We consciously manipulate most of what is available to us, but not all. There is something else we can use. I often think that brilliant work demands a keen understanding of the magical visual language that informs design.
Embracing an established visual language
This is a language whose alphabet is shapes, structures, colours, lines and rhythms. When effective, it is somewhat invisible, subliminally enforcing messages and evoking meaning, using methods solidly rooted in a grammar perceptible in virtually all extraordinary creative work. The syntax for art, architecture, film, and furniture, industrial and graphic design (think Bauhaus and the Swiss style perhaps), this language urges us to become fluent if we aim for a more powerful dialogue with our audience.
Figure 1: Structures (clockwise from top-left): Informal; Formal; Active; Visible.
The greatest creative minds our world has produced could understand some or all of this language. Line and point, form and shape. Abstract objects. Formal and informal structures. Visual distribution. Balance, composition and the multitudinous approaches to symmetry. Patterns and texture. Movement and paths. Repetition, rhythm and frequency. Colour theory. Whitespace and the pause. The list goes on.
The genius we perceive in our creative heroes is often a composite of experience, trial and error, conviction, intuition – even accident – but rarely does great work arise without an initial understanding of the nuts and bolts that help communicate an idea or emotion.
Our world of interactivity
As web designers, our connection with this language is most evident in graphic design. With more technological ease and power comes the responsibility to understand, wisely use, and be able to justify many of our decisions. We have moved beyond the scope of print into a world of interactivity, but we shouldn’t let go of any established principles without good reason.
Figure 2: Understanding movement of objects in any direction along a defined path.
For example, immersion in this visual language can improve our implementation of CSS3 and JavaScript behaviour. With CSS3, we’ve seen a resurgence in CSS experimentation, some of which has been wonderful, but much of it has appeared clumsy. In the race to make something spin, twist, flip or fly from one corner to another, the designer sometimes fails to think about the true movement they seek to emulate. What forces are supposedly affecting this movement? What is the expected path of this transition and is it being respected?
Stopping to think about what is really supposed to be happening on the page compels us to use complex animations, diagrams and rotations more carefully. It helps us to better understand paths and movement.
Figure 3: Repetition can occur through variations in colour, shape, direction, and so on.
It can only be of greater benefit to be mindful of symmetries, depth, affordance, juxtaposition, balance, economy and reduction. A deeper understanding of basic structures can help us to say more with sketches, wireframes, layouts and composition. We’ve all experimented with grids and rhythm but, to truly benefit from these long-established principles, we are duty-bound to understand their possibilities more than we will by simply leveraging a free framework or borrowing some CSS.
Design is not a science, but…
Threading through all of this is what we have learned from science, and what it teaches us of the human brain. This visual language matters because technology changes but, for the most part, people don’t. For centuries, we humans have received and interpreted information in much the same way. Understanding more of how we perceive meaning can help designers make smarter decisions, and call on visual language to underpin these decisions. It is our responsibility as designers to be aware of mental models, mapping, semiotics, sensory experience and human emotion.
Design itself is not a science, but the appropriate use of visual language and scientific understanding exposes the line between effective and awkward, between communicative and mute. By strengthening our mental and analytical approach to what is often done arbitrarily or “because it feels right”, we simply become better designers.
A visual language for the web
So, I’ve outlined numerous starting points and areas worthy of deeper investigation, and hopefully you’re eager to do some research. However, I’ve mostly discussed established ideas and principles that we as web designers can learn from. It’s my belief that our community has a shared responsibility to expand this visual language as it applies to the ebb and flow of the web. Indulge me as I conclude with a related tangent.
In defining a visual language specifically for the web, we must continue to mature. The old powerfully influences the new, but we must intelligently expand the visual language of masterful work and articulate what is uniquely ours.
For example, phrases like Ethan Marcotte’s Responsive Web Design aren’t merely elegant, they describe a new way of thinking and working, of communicating about designs and interaction patterns. These phrases broaden our vocabulary and are immediately adopted by designers worldwide, in both conversation and execution.
Our legacy
Our new definitions should flex and not be tied to specific devices or methods which fade away or morph with time. Our legacy is perhaps more about robust and flexible patterns and systems than it is about specific devices or programming languages.
Figure 4: As web designers, we should think about systems, not pages.
The established principles we adopt and whatever new ways of thinking we define should slip neatly into a wider philosophy about our approach to web design. We’re called, as a community, to define what is distinctive about the visual language of the web, create this vocabulary, this dialect that resonates with us and moves us forward as we tackle each day’s work. Let’s give it some thought.
Further reading
This is my immediate “go-to” list of books that I bullishly believe all web designers should own, but there is so much more out there to read. Sadly, many great texts relating to this stuff are often out of print. Feel free to share your recommendations.

232,Optimize Your Web Design Workflow,"I’m not sure about you, but I still favour using Photoshop to create my designs for the web. I agree that this application, even with its never-ending feature set, is not the perfect environment to design websites in. The ideal application doesn’t exist yet, however, so until it does it’s maybe not such a bad idea to investigate ways to optimize our workflow.
Why use Photoshop?
It will probably not come as a surprise if I say that Photoshop and Illustrator are the applications that I know best and feel most comfortable and creative in. Some people prefer Fireworks for web design. Even though I understand people’s motivations, I still prefer Photoshop personally. On the occasions that I gave Fireworks a try, I ended up just using the application to export my images as slices, or to prepare a dummy for the client. For some reason, I’ve never been able to find my way in that app. There were always certain things missing that could only be done in either Photoshop or Illustrator, which bothered me.
Why not start in the browser?
These days, with CSS3 styling emerging, there are people who find it more efficient to design in the browser. I agree that at a certain point, once the basic design is all set and defined, you can jump right into the code and go from there. But the actual creative part, at least for me, needs to be done in an application such as Photoshop.
As a designer I need to be able to create and experiment with shapes on the fly, draw things, move them around, change colours, gradients, effects, and so on. I can’t see me doing this with code. I’m sure if I switch to markup too quickly, I might end up with a rather boxy and less interesting design. Once I start playing with markup, I leave my typical ‘design zone’. My brain starts thinking differently – more rational and practical, if you know what I mean; I start to structure and analyse how to mark up my design in the most efficient semantic way. When I design, I tend to let that go for a bit. I think more freely and not so much about the limitations, as it might hinder my creativity. Now that you know my motivations to stick with Photoshop for the time being, let’s see how we can optimize this beast.
Optimize your Photoshop workspace
In Photoshop CS5 you have a few default workspace options to choose from which can be found at the top right in the Application Bar (Window > Application Bar).
You can set up your panels and palettes the way you want, starting from the ‘Design’ workspace option, and save this workspace for future web work. Here is how I have set up things for when I work on a website design:
I have the layers palette open, and I keep the other palettes collapsed. Sometimes, when space permits, I open them all. For designers who work both on print and web, I think it’s worthwhile to save a workspace for both, or for when you’re doing photo retouching.
Set up a grid
When you work a lot with Shape Layers like I do, it’s really helpful to enable the Grid (View > Show > Grid) in combination with Snap to Grid (View > Snap To > Grid). This way, your vector-based work will be pixel-sharp, as it will always snap to the grid, and so you don’t end up with blurry borders.
To set up your preferred grid, go to Preferences > Guides, Grids and Slices. A good setting is to use ‘Gridline Every 10 pixels’ and ‘Subdivision 10’. You can switch it on and off at any time using the shortcut Cmd/Ctrl + ’.
It might also help to turn on Smart Guides (View > Show > Smart Guides).
Another important tip for making sure your Shape Layer boxes and other shapes are perfectly aligned to the pixel grid when you draw them is to enable Snap to Pixels. This option can be enabled in the Application bar in the Geometry options dropdown menu when you select one of the shape tools from the toolbox.
Use Shape Layers
To keep your design as flexible as possible, it’s a good thing to use Shape Layers wherever you can as they are scalable. I use them when I design for the iPhone. All my icons, buttons, backgrounds, illustrative graphics – they are all either Smart Objects placed from Illustrator, or Shape Layers. This way, the design is scalable for the retina display.
Use Smart Objects
Among the things I like a lot in Photoshop are Smart Objects. Smart Objects preserve an image’s source content with all its original characteristics, enabling you to perform non-destructive editing to the layer. For me, this is the ideal way of making my design flexible.
For example, a lot of elements are created in Illustrator and are purely vector-based. Placing these elements in Photoshop as Smart Objects (via copy and paste, or dragging from Illustrator into Photoshop) will keep them vector-based and scalable at all times without loss of quality.
Another way you could use Smart Objects is whenever you have repeating elements; for example, if you have a stream or list of repeating items. You could, for instance, create one, two or three different items (for the sake of randomness), make each one a Smart Object, and repeat them to create the list. Then, when you have to update, you need only change the Smart Object, and the update will be automatically applied in all its linked instances.
Turning photos into Smart Objects before you resize them is also worth considering – you never know when you’ll need that same photo just a bit bigger. It keeps things more flexible, as you leave room to resize the image at a later stage. I use this in combination with the Smart Filters a lot, as it gives me such great flexibility.
I usually use Smart Objects as well for the main sections of a web page, which are repeated across different pages of a site. So, for elements such as the header, footer and sidebar, it can be handy for bigger projects that are constantly evolving, where you have to create a lot of different pages in Photoshop.
You could save a template page that has the main sections set up as Smart Objects, always in their latest version. Each time you need to create new page, you can start from that template file. If you need to update an existing page because the footer (or sidebar, or header) has been updated, you can drag the updated Smart Object into this page. Although, do I wish Photoshop made it possible to have Smart Objects live as separate files, which are then linked to my different pages. Then, whenever I update the Smart Object, the pages are automatically updated next time I open the file. This is how linked files work in InDesign and Illustrator when you place a external image.
Use Layer Comps
In some situations, using Layer Comps can come in handy. I try to use them when the design consists of different states; for example, if there are hidden and show states of certain content, such as when content is shown after clicking a certain button. It can be useful to create a Layer Comp for each state. So, when you switch between the two Layer Comps, you’re switching between the two states.
It’s OK to move or hide content in each of these states, as well as apply different layer styles. I find this particularly useful when I need to save separate JPEG versions of each state to show to the client, instead of going over all the eye icons in the layers palette to turn the layers’ visibility on or off.
Create a set of custom colour swatches
I tend to use a distinct colour Swatches palette for each project I work on, by saving a separate Swatches palette in project’s folder (as an .ase file). You can do this through the palette’s dropdown menu, choosing Save Swatches for Exchange.
Selecting this option gives you the flexibility to load this palette in other Adobe applications like Illustrator, InDesign or Fireworks. This way, you have the colours of any particular project at hand. I name each colour, using the hexadecimal values.
Loading, saving or changing the view of the Swatches palette can be done via the palette’s dropdown menu. My preferred view is ‘Small List’ so I can see the hexadecimal values or other info I have added in the description.
I do wish Photoshop had the option of loading several different Styles palettes, so I could have two or more of them open at the same time, but each as a separate palette. This would be handy whenever I switch to another project, as I’m usually working on more than one project in a day. At the moment, you can only add a set of colours to the palette that is already open, which is frustrating and inefficient if you need to update the palette of a project separately.
Create a set of custom Styles
Just like saving a Swatches palette, I also always save the styles I apply in the Styles palette as a separate Styles file in the project’s folder when I work on a website design or design for iPhone/iPad. During the design process, I can save it each time styles are added. Again, though, it would be great if we could have different Styles palettes open at the same time.
Use a scratch file
What I also find particularly timesaving, when working on a large project, is using some kind of scratch file. By that, I mean a file that has elements in place that you reuse a lot in the general design. Think of buttons, icons and so on, that you need in every page or screen design. This is great for both web design work and iPad/iPhone work.
Use the slice tool
This might not be something you think of at first, because you probably associate this way of working with ‘old-school’ table-based techniques. Still, you can apply your slice any way you want, keeping your way of working in mind. Just think about it for a second. If you use the slice tool, and you give each slice its proper filename, you don’t have to worry about it when you need to do updates on the slice or image. Photoshop will remember what the image of that slice is called and which ‘Save for Web’ export settings you’ve used for it. You can also export multiple slices all at once, or export only the ones you need using ‘Save selected slices’.
I hope this list of optimization tips was useful, and that they will help you improve and enjoy your time in Photoshop. That is, until the ultimate web design application makes its appearance. Somebody is building this as we speak, right?",2010,Veerle Pieters,veerlepieters,2010-12-10T00:00:00+00:00,https://24ways.org/2010/optimize-your-web-design-workflow/,process
236,Extreme Design,"Recently, I set out with twelve other designers and developers for a 19th century fortress on the Channel Island of Alderney. We were going to /dev/fort, a sort of band camp for geeks. Our cohort’s mission: to think up, build and finish something – without readily available internet access.

Wait, no internet?
Well, pretty much. As the creators of /dev/fort James Aylett and Mark Norman Francis put it: “Imagine a place with no distractions – no IM, no Twitter”. But also no way to quickly look up a design pattern, code sample or source material. Like packing for camping, /dev/fort means bringing everything you’ll need on your back or your hard drive: from long johns to your favourite icon set.
We got to work the first night discussing ideas for what we wanted to build. By the time breakfast was cleared up the next morning, we’d settled on Russ’s idea to make the Apollo 13 (PDF) transcript accessible. Days two and three were spent collaboratively planning (KJ style) what features we wanted to build, and unravelling the larger UX challenges of the project. The next five days were spent building it. Within 36 hours of touchdown at Southampton Airport, we launched our creation: spacelog.org
The weather was cold, the coal fire less than ideal, food and supplies a hike away, and the process lightning-fast. A week of designing under extreme circumstances called for an extreme process. Some of this was driven by James’s and Norm’s experience running these things, but a lot of it materialised while we were there – especially for our three-strong design team (myself, Gavin O’ Carroll and Chris Govias) who, though we knew each other, had never worked together as a group in this kind of scenario before.
The outcome was a pretty spectacular process, with a some key takeaways useful for any small group trying to build something quickly.
What it’s like inside the fort
/dev/fort has the pressure and pace of a hack day without being a hack day – primarily, no workshops or interruptions‚ but also a different mentality. While hack days are typically developer-driven with a ‘hack first, design later (if at all)’ attitude, James was quick to tell the team to hold off from writing any code until we had a plan. This put a healthy pressure on the design and product folks to slash through the UX problems before we started building.
While the fort had definitely more of a hack day feel, all of us were familiar with Agile methods, so we borrowed a few useful techniques such as morning stand-ups and an emphasis on teamwork. We cut some really good features to make our launch date, and chunked the work based on user goals, iterating as we went.
What made this design process work?
A golden ratio of teams
My personal experience both professionally and in free-form situations like this, is a tendency to get/hire a designer. Leaders of businesses, founders of start-ups, organisers of events: one designer is not enough! Finding one ace-blooded designer who can ‘do everything’ will always result in bottleneck and burnout. Like the nuances between different development languages, design is a multifaceted discipline, and very few can claim to be equally strong in every aspect. Overlap in skill set will result in a stronger, more robust interface.
More importantly, however, having lots of designers to go around meant that we all had the opportunity to pair with developers, polishing the details that don’t usually get polished. As soon as we launched, the public reception of the design and UX was overwhelmingly positive (proof!). But also, a lot of people asked us who the designer was, attributing it to one person.
While it’s important to note that everyone in our team was multitalented (and could easily shift between roles, helping us all stay unblocked), the golden ratio James and Norm devised was two product/developer folks, three interaction designers and eight developers.

Equality inside the fortress walls
Something magical about the fort is how everyone leaves the outside world on the drawbridge. Job titles, professional status, Twitter followers, and so on. Like scout camp, a mutual respect and trust is expected of all the participants. Like extreme programming, extreme design requires us all to be equal partners in a collaborative team. I think this is especially worth noting for designers; our past is filled with the clear hierarchy of the traditional studio system which, however important for taste and style, seems less compatible with modern web/software development methods.
Being equal doesn’t mean being the same, however. We established clear roles and teams for ourselves on the second day, deferring to that person when a decision needed to be made. As the interface coalesced, the designers and developers took ownership over certain parts to ensure the details got looked after, while staying open to ideas and revisions from the rest of the cohort.
Create a space where everyone who enters is equal, but be sure to establish clear roles. Even if it’s just for a short while, the environment will be beneficial.

Hang your heraldry from the rafters
Forts and castles are full of lore: coats of arms; paintings of battles; suits of armour. It’s impossible not to be surrounded by these stories, words and ways of thinking. Like the whiteboards on the walls, putting organisational lore in your physical surroundings makes it impossible not to see.
Ryan Alexander brought some of those static-cling whiteboard sheets which were quickly filled with use cases; IA; team roles; and, most importantly, a glossary. As soon as we started working on the project, we realised we needed to get clear on what certain words meant: what was a logline, a range, a phase, a key moment? Were the back-end people using these words in the same way design and product was? Quickly writing up a glossary of terms meant everyone was instantly speaking the same language. There was no “Ah, I misunderstood because in the data structure x means y” or, even worse, accidental seepage of technical language into the user interface copy.
Put a glossary of your internal terminology somewhere big and fat on the wall. Stand around it and argue until you agree on what it says. Leave it up; don’t underestimate the power of ambient communication and physical reference.
Plan more, download less
While internet is forbidden inside the fort, we did go on downloading expeditions: NASA photography; code documentation; and so on. The project wouldn’t have been possible without a few trips to the web. We had two lists on the wall: groceries and supplies; internets – “loo roll; Tom Stafford photo“.
This changed our usual design process, forcing us to plan carefully and think of what we needed ahead of time. Getting to the internet was a thirty-minute hike up a snow covered cliff to the town airport, so you really had to need it, too.
The path to the internet
For the visual design, especially, this resulted in more focus up front, and communication between the designers on what assets we required. It made us make decisions earlier and stick with them, creating less distraction and churn later in the process.
Try it at home: unplug once you’ve got the things you need. As an artist, it’s easier to let your inner voice shine through if you’re not looking at other people’s work while creating.
Social design
Finally, our design team experimented with a collaborative approach to wireframing. Once we had collectively nailed down use cases, IA, user journeys and other critical artefacts, we tried a pairing approach. One person drew in Illustrator in real time as the other two articulated what to draw. (This would work equally well with two people, but with three it meant that one of us could jump up and consult the lore on the walls or clarify a technical detail.) The result: we ended up considering more alternatives and quickly rallying around one solution, and resolved difficult problems more quickly.
At a certain stage we discovered it was more efficient for one person to take over – this happened around the time when the basic wireframes existed in Illustrator and we’d collectively run through the use cases, making sure that everything was accounted for in a broad sense. At this point, take a break, go have a beer, and give yourself a pat on the back.
Put the files somewhere accessible so everyone can use them as their base, and divide up the more detailed UI problems, screens or journeys. At this level of detail it’s better to have your personal headspace.
Gavin called this ‘social design’. Chatting and drawing in real time turned what was normally a rather solitary act into a very social process, with some really promising results. I’d tried something like this before with product or developer folks, and it can work – but there’s something really beautiful about switching places and everyone involved being equally quick at drawing. That’s not something you get with non-designers, and frequent swapping of the ‘driver’ and ‘observer’ roles is a key aspect to pairing.
Tackle the forest collectively and the trees individually – it will make your framework more robust and your details more polished. Win/win.
The return home
Grateful to see a 3G signal on our phones again, our flight off the island was delayed, allowing for a flurry of domain name look-ups, Twitter catch-up, and e-mails to loved ones. A week in an isolated fort really made me appreciate continuous connectivity, but also just how unique some of these processes might be.
You just never know what crazy place you might be designing from next.",2010,Hannah Donovan,hannahdonovan,2010-12-09T00:00:00+00:00,https://24ways.org/2010/extreme-design/,process
237,Circles of Confusion,"Long before I worked on the web, I specialised in training photographers how to use large format, 5×4″ and 10×8″ view cameras – film cameras with swing and tilt movements, bellows and upside down, back to front images viewed on dim, ground glass screens. It’s been fifteen years since I clicked a shutter on a view camera, but some things have stayed with me from those years.
In photography, even the best lenses don’t focus light onto a point (infinitely small in size) but onto ‘spots’ or circles in the ‘film/image plane’. These circles of light have dimensions, despite being microscopically small. They’re known as ‘circles of confusion’.
As circles of light become larger, the more unsharp parts of a photograph appear. On the flip side, when circles are smaller, an image looks sharper and more in focus. This is the basis for photographic depth of field and with that comes the knowledge that no photograph can be perfectly focused, never truly sharp. Instead, photographs can only be ‘acceptably unsharp’.
Acceptable unsharpness is now a concept that’s relevant to the work we make for the web, because often – unless we compromise – websites cannot look or be experienced exactly the same across browsers, devices or platforms. Accepting that fact, and learning to look upon these natural differences as creative opportunities instead of imperfections, can be tough. Deciding which aspects of a design must remain consistent and, therefore, possibly require more time, effort or compromises can be tougher. Circles of confusion can help us, our bosses and our customers make better, more informed decisions.
Acceptable unsharpness
Many clients still demand that every aspect of a design should be ‘sharp’ – that every user must see rounded boxes, gradients and shadows – without regard for the implications. I believe that this stems largely from the fact that they have previously been shown designs – and asked for sign-off – using static images.
It’s also true that in the past, organisations have invested heavily in style guides which, while maybe still useful in offline media, have a strictness that often fails to allow for the flexibility that we need to create experiences that are appropriate to a user’s browser or device capabilities.
We live in an era where web browsers and devices have wide-ranging capabilities, and websites can rarely look or be experienced exactly the same across them. Is a particular typeface vital to a user’s experience of a brand? How important are gradients or shadows? Are rounded corners really that necessary? These decisions determine how ‘sharp’ an element should be across browsers with different capabilities and, therefore, how much time, effort or extra code and images we devote to achieving consistency between them. To help our clients make those decisions, we can use circles of confusion.
Circles of confusion
Using circles of confusion involves plotting aspects of a visual design into a series of concentric circles, starting at the centre with elements that demand the most consistency. Then, work outwards, placing elements in order of their priority so that they become progressively ‘softer’, more defocused as they’re plotted into outer rings.
If layout and typography must remain consistent, place them in the centre circle as they’re aspects of a design that must remain ‘sharp’.
When gradients are important – but not vital – to a user’s experience of a brand, plot them close to, but not in the centre. This makes everyone aware that to achieve consistency, you’ll need to carve out extra images for browsers that don’t support CSS gradients.
If achieving rounded corners or shadows in all browsers isn’t important, place them into outer circles, allowing you to save time by not creating images or employing JavaScript workarounds.
I’ve found plotting aspects of a visual design into circles of confusion is a useful technique when explaining the natural differences between browsers to clients. It sets more realistic expectations and creates an environment for more meaningful discussions about progressive and emerging technologies. Best of all, it enables everyone to make better and more informed decisions about design implementation priorities.
Involving clients allows the implications of the decisions they make more transparent. For me, this has sometimes meant shifting deadlines or it has allowed me to more easily justify an increase in fees. Most important of all, circles of confusion have helped the people that I work with move beyond yesterday’s one-size-fits-all thinking about visual design, towards accepting the rich diversity of today’s web.",2010,Andy Clarke,andyclarke,2010-12-23T00:00:00+00:00,https://24ways.org/2010/circles-of-confusion/,process
219,Speed Up Your Site with Delayed Content,"Speed remains one of the most important factors influencing the success of any website, and the first rule of performance (according to Yahoo!) is reducing the number of HTTP requests. Over the last few years we’ve seen techniques like sprites and combo CSS/JavaScript files used to reduce the number of HTTP requests. But there’s one area where large numbers of HTTP requests are still a fact of life: the small avatars attached to the comments on articles like this one.
Avatars
Many sites like 24 ways use a fantastic service called Gravatar to provide user images. As a user, you can sign up to Gravatar, give them your e-mail address, and upload an image to represent you. Sites can then include your image by generating a one way hash of your e-mail address and using that to build an image URL. For example, the markup for the comments on this page looks something like this:
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:
Let’s replace the
![]()
element with a data-gravatar-hash attribute on the
element:
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 '![]()
'
})
})
This code waits until everything on the page is loaded, then uses jQuery.prepend to insert an image into every link containing a data-gravatar-hash attribute. It’s short and relatively simple, but in tests it reduced the rendering time of a sample page from over three seconds to well under one.
Finishing touches
We still need to consider the appearance of the page before the avatars have loaded. When our script adds extra content to the page it will cause a browser reflow, which is visually annoying. We can avoid this by using CSS to reserve some space for each image before it’s inserted into the HTML:
#comments div {
padding-left: 110px;
min-height: 100px;
position: relative;
}
#comments div h4 img {
display: block;
position: absolute;
top: 0;
left: 0;
}
In a real world example, we’ll also find that the HTML for a comment is more varied as many users don’t provide a web page link. We can make small changes to our JavaScript and CSS to handle this case.
Put this all together and you get this example.
Taking this idea further
There’s no reason to limit this technique to sites using Gravatar; we can use similar code to delay loading any images that don’t need to be present immediately. For example, this year’s redesigned Flickr photo page uses a “data-defer-src” attribute to describe any image that doesn’t need to be loaded straight away, including avatars and map tiles.
You also don’t have to limit yourself to loading the extra resources once the page loads. You can get further bandwidth savings by waiting until the user takes an action before downloading extra assets. Amazon has taken this tactic to the extreme on its product pages – extra content is loaded as you scroll down the page.
So next time you’re building a page, take a few minutes to think about which elements are peripheral and could be delayed to allow more important content to appear as quickly as possible.",2010,Paul Hammond,paulhammond,2010-12-18T00:00:00+00:00,https://24ways.org/2010/speed-up-your-site-with-delayed-content/,ux
