73 How to Make Your Site Look Half-Decent in Half an Hour Programmers like me are often intimidated by design – but a little effort can give a huge return on investment. Here are one coder’s tips for making any site quickly look more professional. I am a programmer. I am not a designer. I have a degree in computer science, and I don’t mind Comic Sans. (It looks cheerful. Move on.) But although I am a programmer, I want to make my sites look attractive. This is partly out of vanity, and partly realism. Vanity because I want people to think my work is good, and realism because the research shows that people won’t think a site is credible unless it also looks attractive. For a very long time after I became a programmer, I was scared of design. Design seemed to consist of complicated rules that weren’t written down anywhere, plus an unlearnable sense of taste, possessed only by a black-clad elite. But a little while ago, I decided to do my best to hack what it took to make my own projects look vaguely attractive. And although this doesn’t come close to the effect a professional designer could achieve, gathering these resources for improving a site’s look and feel has been really helpful. If I hadn’t figured out some basic design shortcuts, it’s unlikely that a weekend hack of mine would have ended up on page three of the Daily Mail. And too often now, I see excellent programming projects that don’t reach the audience they deserve, simply because their design doesn’t match their execution. So, if you are a developer, my Christmas present to you is this: my own collection of hacks that, used rightly, can make your personal programming projects look professional, quickly. None are hard to learn, most are free, and they let you focus on writing code. One thing to note about these tips, though. They are a personal, pragmatic compilation. They are suggestions, not a definitive guide. You will definitely get better results by working with a professional designer, and by studying design more deeply. If you are a designer, I would love to hear your suggestions for the best tools that I’ve missed, and I’d love to know how we programmers can do things better. With that, on to the tools… 1. Use Bootstrap If you’re not already using Bootstrap, start now. I really think that Bootstrap is one of the most significant technical achievements of the last few years: it democratizes the whole process of web design. Essentially, Bootstrap is a a grid system, with a bunch of common elements. So you can lay your site out how you want, drop in simple elements like forms and tables, and get a good-looking, consistent result, without spending hours fiddling with CSS. You just need HTML. Another massive upside is that it makes it easy to make any site responsive, so you don’t have to worry about writing media queries. Go, get Bootstrap and check out the examples. To keep your site lightweight, you can customize your download to include only the elements you want. If you have more time, then Mark Otto’s article on why and how Bootstrap was created at Twitter is well worth a read. 2. Pimp Bootstrap Using Bootstrap is already a significant advance on not using Bootstrap, and massively reduces the tedium of front-end development. But you also run the risk of creating Yet Another Bootstrap Site, or Hack Day Design, as it’s known. If you’re really pressed for time, you could buy a theme from Wrap Bootstrap. These are usually created by professional designers, and will give a polish that we can’t achieve ourselves. Your site won’t be unique, but it will look good quickly. Luckily, it’s pretty easy to make Bootstrap not look too much like Bootstrap – using fonts, CSS effects, background images, colour schemes and so on. Most of the rest of this article covers different ways to achieve this. We are going to customize this Bootstrap example page. This already has some custom CSS in the <head>. We’ll pull it all out, and create a new CSS file, custom.css. Then we add a reference to it in the header. Now we’re ready to start customizing things. 3. Fonts Web fonts are one of the quickest ways to make your site look distinctive, modern, and less Bootstrappy, so we’ll start there. First, we can add some sweet fonts, from Google Web Fonts. The intimidating bit is choosing fonts that look nice together. Luckily, there are plenty of suggestions around the web: we’re going to use one of DesignShack’s suggested free Google Fonts pairings. Our fonts are Corben (for headings) and Nobile (for body copy). Then we add these files to our <head>. <link href="http://fonts.googleapis.com/css?family=Corben:bold" rel="stylesheet" type="text/css"> <link href="http://fonts.googleapis.com/css?family=Nobile" rel="stylesheet" type="text/css"> …and this to custom.css: h1, h2, h3, h4, h5, h6 { font-family: 'Corben', Georgia, Times, serif; } p, div { font-family: 'Nobile', Helvetica, Arial, sans-serif; } Now our example looks like this. It’s not going to win any design awards, but it’s immediately better: I also recommend the web font services Fontdeck, or Typekit – these have a wider selection of fonts, and are worth the investment if you regularly need to make sites look good. For more font combinations, Just My Type suggests appealing pairings from Typekit. Finally, you can experiment with type pairing ideas at Type Connection. For the design background on pairing fonts, Typekit’s post is worth a read. 4. Textures An instant way to make a site look classy is to use textures. You know the grey, stripy, indefinably elegant background on 24ways.org? That. If only there was a superb resource listing attractive, free, ready-to-use textures… Oh wait, there’s Atle Mo’s Subtle Patterns. We’re going to use Cream Dust, for an effect that can only be described as subtle. We download the file to a new /img/ directory, then add this to the CSS file: body { background: url(/img/cream_dust.png) repeat 0 0; } Bang: For some design background on patterns, I recommend reading through Smashing Magazine’s guidelines on textures. (TL;DR version: use textures to enhance beauty, and clarify the information architecture of your site; but don’t overdo it, or inadvertently obscure your text.) Still more to do, though. Onwards. 5. Icons Last year’s 24 ways taught us to use icon fonts for our site icons. This is great for the time-pressed coder, because icon fonts don’t just cut down on HTTP requests – they’re a lot quicker to set up than image-based icons, too. Bootstrap ships with an extensive, free for commercial use icon set in the shape of Font Awesome. Its icons are safe for screen readers, and can even be made to work in IE7 if needed (we’re not going to bother here). To start using these icons, just download Font Awesome, and add the /fonts/ directory to your site and the font-awesome.css file into your /css/ directory. Then add a reference to the CSS file in your header: <link rel="stylesheet" href="/css/font-awesome.css"> Finally, we’ll add a truck icon to the main action button, as follows. Why a truck? Why not? <a class="btn btn-large btn-success" href="#"><i class="icon-truck"></i> Sign up today</a> We’ll also tweak our CSS file to stop the icon nudging up against the button text: .jumbotron .btn i { margin-right: 8px; } And this is how it looks: Not the most exciting change ever, but it livens up the page a bit. The licence is CC-BY-3.0, so we also include a mention of Font Awesome and its URL in the source code. If you’d like something a little more distinctive, Shifticons lets you pay a few cents for individual icons, with the bonus that you only have to serve the icons you actually use, which is more efficient. Its icons are also friendly to screen readers, but won’t work in IE7. 6. CSS3 The next thing you could do is add some CSS3 goodness. It can really help the key elements of the site stand out. If you are pressed for time, just adding box-shadow and text-shadow to emphasize headings and standouts can be useful: h1 { text-shadow: 1px 1px 1px #ccc; } .div-that-you want-to-stand-out { box-shadow: 0 0 1em 1em #ccc; } We have a little more time though, so we’re going to do something more subtle. We’ll add a radial gradient behind the main heading, using an online gradient editor. The output is hefty, but you can see it in the CSS. Note that we also need to add the following to our HTML, for IE9 support: <!--[if gte IE 9]> <style type="text/css"> .gradient { filter: none; } </style> <![endif]--> And the effect – I don’t know what a designer would think, but I like the way it makes the heading pop. For a crash course in useful modern CSS effects, I highly recommend CodeSchool’s online course in Functional HTM5 and CSS3. It costs money ($25 a month to subscribe), but it’s worth it for the time you’ll save. As a bonus, you also get access to some excellent JavaScript, Ruby and GitHub courses. (Incidentally, if you find yourself fighting with basic float and display attributes in CSS – and there’s no shame in it, CSS layout is not intuitive – I recommend the CSS Cross-Country course at CodeSchool.) 7. Add a twist We could leave it there, but we’re going to add a background image, and give the site some personality. This is the area of design that I think many programmers find most intimidating. How do we create the graphics and photographs that a designer would use? The answer is iStockPhoto and its competitors – online image libraries where you can find and pay for images. They won’t be unique, but for our purposes, that’s fine. We’re going to use a Christmassy image. For a twist, we’re going to use Backstretch to make it responsive. We must pay for the image, then download it to our /img/ directory. Then, we set it as our <body>’s background-image, by including a JavaScript file with just the following line: $.backstretch("/img/winter.jpg"); We also reset the subtle pattern to become the background for our container image. It would look much better transparent, so we can use this technique in GIMP to make it see-through: .container-narrow { background: url(/img/cream_dust_transparent.png) repeat 0 0; } We also fiddle with the padding on body and .container-narrow a bit, and this is the result: (Aside: If this were a real site, I’d want to buy images in multiple sizes and ensure that Backstretch chose the most appropriately sized image for our screen, perhaps using responsive images.) How to find the effects that make a site interesting? I keep a set of bookmarks for interesting JavaScript and CSS effects I might want to use someday, from realistic shadows to animating grids. The JavaScript Weekly newsletter is a great source of ideas. 8. Colour schemes We’re just about getting there – though we’re probably past half an hour now – but that button and that menu still both look awfully Bootstrappy. Real sites, with real designers, have a colour palette, carefully chosen to harmonize and match the brand profile. For our purposes, we’re just going to borrow some colours from the image. We use Gimp’s colour picker tool to identify the hex values of the blue of the snow. Then we can use Color Scheme Designer to find contrasting, but complementary, colours. Finally, we use those colours for our central button. There are lots of tools to help us do this, such as Bootstrap Buttons. The new HTML is quite long, so I won’t paste it all here, but you can find it in the CSS file. We also reset the colour of the pills in the navigation menu, which is a bit easier: .nav-pills > .active > a, .nav-pills > .active > a:hover { background-color: #FF9473; } I’m not sure if the result is great to be honest, but at least we’ve lost those Bootstrap-blue buttons: Another way to do it, if you didn’t have an image to match, would be to borrow an attractive colour scheme. Colourlovers is a community where people create and share ready-made colour palettes. The key thing is to find a palette with an open licence, so you can legitimately use it. Unfortunately, you can’t search for palettes by licence type, but many do have open licences. Here’s a popular palette with a CC-BY-SA licence that allows reuse with attribution. As above, you can use the hex values from the palette in your custom CSS, and bask in the newly colourful results. 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. 2012 Anna Powell-Smith annapowellsmith 2012-12-16T00:00:00+00:00 https://24ways.org/2012/how-to-make-your-site-look-half-decent/ design
74 Should We Be Reactive? Evolution Looking at the evolution of the web and the devices we use should help remind us that the times we’re adjusting to are just another step on a journey. These times seem to be telling us that we need to embrace flexibility. Imagine an HTML file containing nothing but text. It’s viewable on any web-capable device and reasonably readable: the notion of the universality of the web was very much a founding principle. Right from the beginning, browser vendors understood that we’d want text to reflow (why wouldn’t we?), so I consider the first websites to have been fluid. As we attempted to exert more control through our designs in the early days of the web, debates about whether we should produce fixed or fluid sites raged. We could create fluid designs using tables, but what we didn’t have then was a wide range of web capable devices or the ability to control this fluidity. The biggest changes occurred when stats showed enough people using a different screen resolution we could cater for. To me, the techniques of responsive web design provide the control we were missing. Combining new approaches to layout and images with media queries empowered us to learn how to embrace the inherent flexibility of the web in ways to suit our work and the devices used by our audience. Perhaps another kind of flexibility might be found in how we use context to affect how we present our content; to consider how we might use the information we can access from people, browsers and devices to provide web experiences – effectively creating sites that react to initial or changing circumstances in the relationship between people and our content. Embracing flexibility So what is context? Put simply, you could think of it as a secondary piece of information that helps clarify the meaning of the first. It helps set a scene or describe circumstances. I think that Cennydd Bowles has summed it up really well through talks he’s given recently, in which he’s arrived at the acronym DETAILS (Device, Environment, Time, Activity, Individual, Location, Social) – I encourage you to keep an eye out for his next book due in the new year where he’ll explore this idea much further. This clarity over what context could mean in terms of what we do on the web is fundamental, directing us towards ways we might use it. When you stop to think about it, we’ve been using some basic pieces of this information right from the beginning, like bits of JavaScript or Java applets that serve an appropriate greeting to your site’s visitors, or show their location, or even local weather. But what if we think of this from the beginning of our projects? We should think about our content first. Once we know this and have a direction, perhaps then we can think about what context, or even multiple contexts, might help us to communicate more effectively. The real world There’s always been a disconnect between the real world and the web, which is to be expected. But the world around us is a sea of data; every fundamental building block: people, places, events and things have information waiting to be explored. For sites based around physical objects or locations, this divide is really apparent. We don’t ordinarily take the time to describe in code the properties of a place, or consider whether your relationship to the place in the real world should have any impact on your relationship with a site about it. When I think about local businesses, they have such rich properties to draw on and yet we don’t really explore them in any meaningful way, even through something as simple as opening hours. Now we have data… We’ve long had access to the current time both on server- and client-sides. The use of geolocation is easier than ever, but when we look at the range of information we could glean to help us make some choices, maybe there’s some help on the horizon from projects like the W3C Device APIs Working Group. This might prove useful to help make us aware of network and battery conditions of a device, along with the potential to gain data from other sensors, which could tell us about lighting conditions, ambient noise levels and temperature depending on the capabilities of the device. It may be that our sites have some form of login or access to your profile from another site. Along with data from our devices and browsers, this should give us a sense of how best to talk to our audience in certain situations. We don’t necessarily need to know any personal details, just enough to make decisions about how to present our sites. The reactive web? So why reactive web design? I’m hoping that a name might help us to have a common vocabulary not only about what we mean when we talk about context, but how it could be considered through our projects, right from the early stages. How could this manifest itself? A simple example might be a location-aware panel on your site. Perhaps the space is a little down in your content hierarchy but serves a perfectly valid purpose by default. To visitors outside the country perhaps this works fine, but within your country maybe this panel could be used to communicate more effectively. Further still, if we knew the visitors were in the vicinity, we could talk to them more directly. What if both time and location were relevant? This space could work as before but you could consider how time could intersect with your local audience. If you know they’re local and it’s a certain time of day, you could communicate directly with them. This example isn’t beyond what banner ads often do and uses easily accessible information. There are more unusual combinations we may be able to find, such as movement and presence. Perhaps a site that tells a story, which changes design and content based on whether you’re moving, how long you’ve been on the site and how far you’ve travelled. This isn’t what we typically expect from websites, but we should bear in mind that what websites are now will not be what they become in the future. You could do much of this contextual presentation through native apps, of course. The Silent History, an app novel written and designed for iPad and iPhone, uses an exploration element, providing “hundreds of location-based stories across the U.S. and around the world. These can be read only when your device’s GPS matches the coordinates of the specified location.” But considering the universality of the web, we could redefine what web-based experiences should be like. Not all methods would work well on the web, but that’s a decision that has to be made for a specific project. By thinking more broadly about any web-capable device, we can use what we know to provide relevant experiences for our site’s visitors. We need to be sure what we mean by relevant, of course! Reality bites While there are incredible possibilities, from a simple panel on a site to something bordering on living sites that evolve and change with our circumstances, we need to act with a degree of pragmatism and understand how much of what we could do is based on assumptions and the bias of our own experiences. We could go wild with changing the way our content is presented based on contextual information, but if we’re not careful what we end up with confuses and could provide a very fractured experience. As much as possible we need to think more ethnographically, observe and question people in the situations we think may be relevant, and test our assumptions as early as we can. Even on small projects, there may be ways we can validate our assumptions and test with our audience. The key to applying contextual content or cues is not to break the experience between contextual views (as I think we now wouldn’t when hiding content on a mobile view). It’s another instance of progressive enhancement – as we know certain pieces of information, we can enhance the experience. Also, if you do change content, how can you not make a more cumbersome experience for your visitors? It’s all about communication Content is at the core of what we do, but if we consider context we need to understand the impact on that. The effect could be as subtle as an altered hierarchy, involve swapping out panels of content, or in extreme instances perhaps all of your content might change. In some ways, this extends the notion of adaptive content that Karen McGrane has been talking about, to how we write and store the content we create. Thinking about the the impact of context may require us to re-evaluate our site structure, too. Whatever we decide, we have to be clear what will happen and manage the expectations of our users. The bottom line What I’m proposing isn’t that we go crazy and end up with a confused, disjointed set of experiences across the web. What I hope is that starting right from the beginning of a project, we think about what context is and could be, and see what relevance it might have to what we’re trying to communicate. This strategic process leads us to think about design. We are slowly adapting to what it means to be flexible through responsive and adaptive processes. What does thinking about contextual states mean to us (or designing for state in general)? Does this highlight again how difficult it’ll be for our tools to keep up with our processes and output? In terms of code, the vast majority of this data comes from the client-side through JavaScript. While we can progressively enhance, this could lead to a lot of code bloat through feature or capability detection, and potentially a lot of conditional loading of scripts. It’s a real shame we don’t get much we can rely on from the server-side – we know how unreliable user agents are! We need to understand why we’d do this. Are we trying to communicate well and be useful, or doing it to show off? Underneath it all, what do we base our decisions on? Do we have actual insight or are we proceeding from our assumptions and the bias of our own experiences? Scott Jenson summed it up best for me: (to paraphrase) the pain we put people through has to be greatly outweighed by the value we offer. I see that this could be another potential step in our evolution on the web; continuing this exploration of the flexibility the web allows us. It’s amazing we can do such incredible things from what is essentially a set of disparate, linked documents. 2012 Dan Donald dandonald 2012-12-09T00:00:00+00:00 https://24ways.org/2012/should-we-be-reactive/ design
77 Colour Accessibility Here’s a quote from Josef Albers: In visual perception a colour is almost never seen as it really is[…] This fact makes colour the most relative medium in art.Josef Albers, Interaction of Color, 1963 Albers was a German abstract painter and teacher, and published a very famous course on colour theory in 1963. Colour is very relative — not just in the way that it appears differently across different devices due to screen quality and colour management, but it can also be seen differently by different people — something we really need to be more mindful of when designing. What is colour blindness? Colour blindness very rarely means that you can’t see any colour at all, or that people see things in greyscale. It’s actually a decreased ability to see colour, or a decreased ability to tell colours apart from one another. How does it happen? Inside the typical human retina, there are two types of receptor cells — rods and cones. Rods are the cells that allow us to see dark and light, and shape and movement. Cones are the cells that allow us to perceive colour. There are three types of cones, each responsible for absorbing blue, red, and green wavelengths in the spectrum. Problems with colour vision occur when one or more of these types of cones are defective or absent entirely, and these problems can either be inherited through genetics, or acquired through trauma, exposure to ultraviolet light, degeneration with age, an effect of diabetes, or other factors. Colour blindness is a sex-linked trait and it’s much more common in men than in women. The most common type of colour blindness is called deuteranomaly which occurs in 7% of males, but only 0.5% of females. That’s a pretty significant portion of the population if you really stop and think about it — we can’t ignore this demographic. What does it look like? People with the most common types of colour blindness, like protanopia and deuteranopia, have difficulty discriminating between red and green hues. There are also forms of colour blindness like tritanopia, which affects perception of blue and yellow hues. Below, you can see what a colour wheel might look like to these different people. What can we do? Here are some things you can do to make your websites and apps more accessible to people with all types of colour blindness. Include colour names and show examples One of the most common annoyances I’ve heard from people who are colour-blind is that they often have difficulty purchasing clothing and they will sometimes need to ask another person for a second opinion on what the colour of the clothing might actually be. While it’s easier to shop online than in a physical store, there are still accessibility issues to consider on shopping websites. Let’s say you’ve got a website that sells T-shirts. If you only show a photo of the shirt, it may be impossible for a person to tell what colour the shirt really is. For clarification, be sure to reference the name of the colour in the description of the product. United Pixelworkers does a great job of following this rule. The St. John’s T-shirt has a quirky palette inspired by the unofficial pink, white and green Newfoundland flag, and I can imagine many people not liking it. Another common problem occurs when a colour filter has been added to a product search. Here’s an example from a clothing website with unlabelled colour swatches, and how that might look to someone with deuteranopia-type colour blindness. The colour search filter below, from the H&M website, is much better since it uses names instead. At first glance, Urban Outfitters also uses unlabelled colour swatches on product pages (below), but on closer inspection, the colour name is displayed on hover. This isn’t an ideal solution, because although it’ll work on a desktop browser, it won’t work on a touchscreen device where hovering isn’t an option. Using overly fancy colour names, like the ones you might find labelling high-end interior paint can be just as confusing as not using a colour name at all. Names like grape instead of purple don’t really give the viewer any useful information about what the colour actually is on a colour wheel. Is grape supposed to be purple, or could it refer to red grapes or even green? Stick with hue names as much as possible. Avoid colour-specific instructions When designing forms, avoid labelling required fields only with coloured text. It’s safer to use a symbol cue like the asterisk which is colour-independent. A similar example would be directing a user to click a green button to purchase a product. Label your buttons clearly and reference them in the site copy by function, not colour, to avoid confusion. Don’t rely on colour coding Designing accessible maps and infographics can be much more challenging. Don’t rely on colour coding alone — try to use a combination of colour and texture or pattern, along with precise labels, and reflect this in the key or legend. Combine a blue background with a crosshatched pattern, or a pink background with a stippled dot — your users will always have two pieces of information to work with. The map of the London subway system is an iconic image not just in London, but around the world. Unfortunately, it contains some colours that are indistinguishable from each other to a person with a vision problem. This is true not only for the London underground, but also for any other wayfinding system that relies on colour coding as the only key in a legend. There are printable versions of the map available online in black and white, using patterns and shades of black and grey that are distinguishable, but the point is that there would be no need for such a map if it were designed with accessibility in mind from the beginning. And, if you’re a person who has a physical disability as well as a vision problem, the “Step-Free” guide map which shows stations is based on the original coloured map. Provide alternatives and customization While it’s best to consider these issues and design your app to be accessible by default, sometimes this might not be possible. Providing alternative styles or allowing users to edit their own colours is a feature to keep in mind. The developers of the game Faster Than Light created an alternate colour-blind mode and asked for public feedback to make sure that it passed the test. Not much needed to be done, but you can see they added stripes to the red zones and changed some outlines to blue. iChat is also a good example. Although by default it uses coloured bubbles to indicate a user’s status (available for chat, away or idle, or busy), included in the preferences is a “User Shapes to Indicate Status” option, which changes the shape of the standard circles to green circles, yellow triangles and red squares. Pay attention to contrast Colours that are similar in value but different in hue may be easy to distinguish between for a user with good vision, but a person who suffers from colour blindness may not be able to tell them apart at all. Proofing your work in greyscale is a quick way to tell if there’s enough contrast between the most important information in your design. Check with a simulator There are many tools out there for simulating different types of colour blindness, and it’s worth checking your design to catch any potential problems up front. One is called Sim Daltonism and it’s available for Mac OS X. It’ll show a pop-up preview next to your cursor and you can choose which type of colour blindness you want to test from a drop-down menu. You can also proof for the two most common types of colour blindness right in Photoshop or Illustrator (CS4 and later) while you’re designing. The colour contrast check tool from designer and developer Jonathan Snook gives you the option to enter a colour code for a background, and a colour code for text, and it’ll tell you if the colour contrast ratio meets the Web Content Accessibility Guidelines 2.0. You can use the built-in sliders to adjust your colours until they meet the compliant contrast ratios. This is a great tool to test your palette before going live. For live websites, you can use the accessibility tool called WAVE, which also has a contrast checker. It’s important to keep in mind, though, that while WAVE can identify contrast errors in text, other things can slip through, so a site that passes the test does not automatically mean it’s accessible in reality. For example, the contrast checker here doesn’t notice that our red link in the introduction isn’t underlined, and therefore could blend into the surrounding paragraph text. I know that once I started getting into the habit of checking my work in a simulator, I became more mindful of any potential problem areas and it was easier to avoid them up front. It’s also made me question everything I see around me and it sends red flags off in my head if I think it’s a serious colour blindness fail. Understanding that colour is relative in the planning stages and following these tips will help us make more accessible design for all. 2012 Geri Coady gericoady 2012-12-04T00:00:00+00:00 https://24ways.org/2012/colour-accessibility/ design
81 Science! Sometimes we want to capture people’s attention at a glance to communicate something fast. At other times we want to have the interface fade away into the background, letting people paint pictures in their minds with our words (if you’ll forgive a little flowery festive flourish). I tend to distinguish between these two broad objectives as designing for impact on the one hand, and designing for immersion on the other. What defines them is interruption. Impact needs an attention-grabbing interruption. Immersion requires us to remove interruption from the interface. Careful design deliberately interrupts but doesn’t accidentally disrupt. If that seems to make sense to you, then you’ll find the following snippets of science as useful as I did. Saccades and fixations As you’re reading this your eyes are skipping along the lines in tiny jumps. During each jump everything is blurred. Each jump ends in a small pause so your brain can take a snapshot of the letters. It arranges them into words, and then parses out the meaning — fast — in around a quarter of a second. The jumps are called saccades. The pauses are called fixations. Sometimes we take regressive saccades, skipping back to reread. There’s a simple example in the excellent little book, Detail in Typography, by Jost Hochuli. If you want to explore the science of reading in much more depth, I recommend the excellent paper, “The Science of Word Recognition”, by Dr Kevin Larson of Microsoft. To design for legibility and readability is to design for saccades and fixations. It’s the craft of making it easy for people’s brains to extract meaning, using techniques like good contrast, font size, spacing and structure, and only interrupting the reading experience deliberately. Scan paths At some point when visiting 24 ways you probably scanned the screen to get orientated. The journey your eyes took is known as a scan path. Scan paths are made up of saccades and fixations. Right now you’re following a scan path as you read, along one line, and down to the next. This is a map of the scan paths found by Olivier Le Meur from observing people looking at Rembrandt’s Leçon d’anatomie: For websites, the scan path is a little different. This is an aggregate scan path of Google from LC Technologies: The average shape of a website scan path becomes clearer in this average scan path taken by forty-six people during research by the Poynter Institute, the Estlow Center for Journalism & New Media, and Eyetools: Just like when we read text arranged left to right in a vertical column, scan paths follow a roughly Z-shaped pattern from the top left to bottom right. Sometimes we skip back to reread a word or sentence, or glance again at a specific element, but the Z-shaped scan path persists. Designing for scan paths is to organise content to help people move through an interface to get orientated, and to read. The elements that are important enough to need impact must interrupt the scan path and clearly call attention to themselves. However, they don’t always need to clip people round the ear from multiple directions at once to get attention. It helps to list elements by importance. That gives us an interruption hierarchy to work with. Elements can then interrupt the design with degrees of contrast to the rest of the content using either positioning, treatment, or both. Ta-da! Impact achieved, but gently. No clips round the ear required. Swinging mood Human beings are resilient. Among the immersion and occasional interruptions, we even like a little disruption, especially if it’s absurd and funny. The Ling’s Cars website proves it. In fact, we’re so resilient that we can work around all kinds of mayhem to get a seemingly simple task done. In one study, “The Aesthetics of Reading” (PDF, 480Kb), Dr Kevin Larson of Microsoft and Dr Rosalind Picard of MIT explored the effect of good typography on mood. Two versions of the New Yorker ePeriodical were created. One was typeset well and the other poorly. They engaged twenty volunteers — half male, half female — and showed the good version to half of the participants. The other half saw the poor version. The good doctors found that, “there are important differences between good and poor typography that appear to have little effect on common performance measures such as reading speed and comprehension.” In short, good typography didn’t help people read faster or comprehend better. Oh. On the face of it that seems to invalidate what we designers do. Hold your horses, though! They also found that “the participants who received the good typography performed better on relative subjective duration and on certain cognitive tasks”, and that “good typography induces a good mood.” This means that even though there were no actual differences in reading speed and comprehension, the people who read the version with good typography thought that it took less time to read, and were induced into a good mood by doing so. Not only that, but by being in a good mood, people were more capable of completing creative tasks faster. That was a revelation to me. It means that the study showed there is a positive, measurable, emotional and perceptual benefit to good typography and design. To paraphrase: time and tasks fly when you’re having fun!

So, among all my talk of saccades, fixations, scan paths and typesetting, there is science, and the science helps us qualify our design decisions when we need to, and do our jobs better. The science helps us understand how people will interact with our work, and what the actual benefits are for them, and the products or organisations we serve. Good design equals a subjectively quicker experience, a good mood, objectively faster completion of tasks, and happiness for everyone. Thank you, science! 2012 Jon Tan jontan 2012-12-24T00:00:00+00:00 https://24ways.org/2012/science/ design
84 Responsive Responsive Design Now more than ever, we’re designing work meant to be viewed along a gradient of different experiences. Responsive web design offers us a way forward, finally allowing us to “design for the ebb and flow of things.” With those two sentences, Ethan closed the article that introduced the web to responsive design. Since then, responsive design has taken the web by storm. Seemingly every day, some company is touting their new responsive redesign. Large brands such as Microsoft, Time and Disney are getting in on the action, blowing away the once common criticism that responsive design was a technique only fit for small blogs. Certainly, this is a good thing. As Ethan and John Allsopp before him, were right to point out, the inherent flexibility of the web is a feature, not a bug. The web’s unique ability to be consumed and interacted with on any number of devices, with any number of input methods is something to be embraced. But there’s one part of the web’s inherent flexibility that seems to be increasingly overlooked: the ability for the web to be interacted with on any number of networks, with a gradient of bandwidth constraints and latency costs, on devices with varying degrees of hardware power. A few months back, Stephanie Rieger tweeted “Shoot me now…responsive design has seemingly become confused with an opportunity to reduce performance rather than improve it.” I would love to disagree, but unfortunately the evidence is damning. Consider the size and number of requests for four highly touted responsive sites that were launched this year: 74 requests, 1,511kb 114 requests, 1,200kb 99 requests, 1,298kb 105 requests, 5,942kb And those numbers were for the small screen versions of each site! These sites were praised for their visual design and responsive nature, and rightfully so. They’re very easy on the eyes and a lot of thought went into their appearance. But the numbers above tell an inconvenient truth: for all the time spent ensuring the visual design was airtight, seemingly very little (if any) attention was given to their performance. It would be one thing if these were the exceptions, but unfortunately they’re not. Guy Podjarny, who has done a lot of research around responsive performance, discovered that 86% of the responsive sites he tested were either the same size or larger on the small screen as they were on the desktop. The reality is that high performance should be a requirement on any web project, not an afterthought. Poor performance has been tied to a decrease in revenue, traffic, conversions, and overall user satisfaction. Case study after case study shows that improving performance, even marginally, will impact the bottom line. The situation is no different on mobile where 71% of people say they expect sites to load as quickly or faster on their phone when compared to the desktop. The bottom line: performance is a fundamental component of the user experience. So, given it’s extreme importance in the success of any web project, why is it that we’re seeing so many bloated responsive sites? First, I adamantly disagree with the belief that poor performance is inherent to responsive design. That’s not a rule – it’s a cop-out. It’s an example of blaming the technique when we should be blaming the implementation. This argument also falls flat because it ignores the fact that the trend of fat sites is increasing on the web in general. While some responsive sites are the worst offenders, it’s hardly an issue resigned to one technique. To fix the issue, we need to stop making excuses and start making improvements instead. Here, then, are some things we can do to start improving the state of responsive performance, and performance in general, right now. Create a culture of performance If you understand just how important performance is to the success of a project, the natural next step is to start creating a culture where high performance is a key consideration. One of the things you can do is set a baseline. Determine the maximum size and number of requests you are going to allow, and don’t let a page go live if either of those numbers is exceeded. The BBC does this with its responsive mobile site. A variation of that, which Steve Souders discussed in a recent podcast is to create a performance budget based on those numbers. Once you have that baseline set, if someone comes along and wants to add a something to the page, they have to make sure the page remains under budget. If it exceeds the budget, you have three options: Optimize an existing feature or asset on the page Remove an existing feature or asset from the page Don’t add the new feature or asset The idea here is that you make performance part of the process instead of something that may or may not get tacked on at the end. Embrace the pain This troubling trend of web bloat can be blamed in part on the lack of pain associated with poor performance. Most of us work on high-speed connections with low latency. When we fire up a 4Mb site, it doesn’t feel so bad. When I tested the previously mentioned 5,942kb site on a 3G network, it took over 93 seconds to load. A minute and a half just staring at a white screen. Had anyone working on that project experienced that, you can bet the site wouldn’t have launched in that state. Don’t just crunch numbers. Fire up your site on a slower network and see what it feels like to wait. If you don’t have access to a slow network, simulate one using a tool like Slowy, Throttle or the Network Conditioner found in Mac OS X 10.7. Watch for low-hanging fruit There are a bunch of general performance improvements that apply to any site (responsive or not) but often aren’t made. A great starting point is to refer to Yahoo!‘s list of rules. Some of this might sound complicated or intimidating, but it doesn’t have to be. You can grab an .htaccess file from HTML 5 Boilerplate or use Sergey Chernyshev’s drop-in .htaccess file. You can use tools like SpriteMe to simplify the creation of sprites, and ImageOptim to compress images. Just by implementing these simple optimizations you will achieve a noticeable improvement in terms of weight and page load time. Be careful with images The most common offender for poor responsive performance is downloading unnecessarily large images, or worse yet, multiple sizes of the same image. For background images, simply being careful with where and how you include the image can ensure you don’t get caught in the trap of multiple background images being downloaded without being used. Don’t count on display:none to help. While it may hide elements from displaying on screen, those images will still be requested and downloaded. Content images can be a little trickier. Whatever you do, don’t serve a large image that works on a large screen display to small screens. It’s wasteful, not only in terms of adding weight to the page, but also in wasting precious memory. Instead, use a tool like Adaptive Images or src.sencha.io to make sure only appropriately sized images are being downloaded. The new <picture> element that has been so often discussed is another excellent solution if you’re feeling particularly future-oriented. A picture polyfill exists so that you can start using the element now without any worries about support. Conditional loading Don’t load any more than you absolutely need to. If a script isn’t needed at certain sizes, use the matchMedia polyfill to ensure it only loads when needed. Use eCSSential to do the same for unnecessary CSS files. Last year on 24 ways, Jeremy Keith wrote an article about conditional loading of content in a responsive design based on the screen width. The technique was later refined by the Filament Group into what they dubbed the Ajax-Include Pattern. It’s a powerful and simple way to lighten the load on small screens as well as reduce clutter. Go vanilla? If you take a look at the HTTP Archive you’ll see that other than image size, JavaScript is the heaviest asset on a page weighing in at 215kb on average. It also boasts the fifth highest correlation to load time as well as the second highest correlation to render time. Much of the weight can be attributed to our industry’s increasing reliance on frameworks. This is especially a concern on mobile devices. PPK recently exclaimed that current JavaScript libraries are just “too heavy for mobile”. “Research from Stoyan Stefanov on parse times supports this. On some Android and iOS devices, it can take as long as 200-300ms just to parse jQuery. There’s nothing wrong about using a framework, but the problem is that they’ve become the default. Before dropping another framework or plugin into a page, we should stop to consider the value it adds and whether we could accomplish what we need to do using a combination of vanilla JavaScript and CSS instead. (This is a great example of a scenario where a performance budget could help.) Start thinking beyond visual aesthetics We love to tout the web’s universality when discussing the need for responsive design. But that universality is not limited simply to screen size. Networks and hardware capabilities must factor in as well. The web is an incredibly dynamic and interactive medium, and designing for it demands that we consider more than just visual aesthetics. Let’s not forget to give those other qualities the attention they deserve. 2012 Tim Kadlec timkadlec 2012-12-05T00:00:00+00:00 https://24ways.org/2012/responsive-responsive-design/ design
93 Design Systems The most important part of responsive web design is that, no matter what the viewport width, the content is accessible in an optimum display. The best responsive designs are those that allow you to go from one optimised display to another, but with the feeling that these experiences are part of a greater product whole. Responsive design: where we’ve been going wrong Responsive web design was a shock to my web designer system. Those of us who had already been designing sites for mobile probably had the biggest leap to make. We might have been detecting user agents in order to deliver a mobile-specific site, or using the slightly more familiar Bushido technique to deliver sites optimised for device type and viewport size, but either way our focus was on devices. A site was optimised for either a mobile phone or a desktop. Responsive web design brought us back to pre-table layout fluid sites that expanded or contracted to fit the viewport. This was a big difference to get our heads around when we were so used to designing for fixed-width layouts. Suddenly, an element could be any width or, at least, we needed to consider its maximum and minimum widths. Pixel perfection, while pretty, became wholly unrealistic, and a whole load of designers who prided themselves in detailed and precise designs got a bit scared. Hanging on to our previous processes and typical deliverables led us to continue to optimise our sites for particular devices and provide pixel-perfect mockups for those device widths. With all this we were concentrating on devices, not content, deliverables and not process, and making assumptions about users and their devices based on nothing but the width of the viewport. I don’t think this is a crime, I think it was inevitable. We can be up to date with our principles and ideals, but it’s never as easy in practice. That’s why it’s more important than ever to share our successful techniques and processes. Let’s drag each other into modern web design. Design systems: the principles What are design systems? A visual design system is built out of the core components of typography, layout, shape or form, and colour. When considering the design of a whole product, a design system should also include patterns in user flow, content strategy, copy, and tone of voice. These concepts, design decisions or rules, created around the core components are used consistently across your product to create a cohesive feel, whether it’s from one element to another, page to page, or viewport width to viewport width. Responsive design is one of the most important considerations in the components of a design system. For each component, you must decide what will unite the design across the viewports to maintain that consistent feel, and what parts of the design will differentiate in order to provide a flexible and optimal experience for different viewport sizes. Components you might keep the same across viewports typeface base unit colour shape/form Components you might differentiate across viewports grids layout font size measure (line length) leading (line height) Content: it must always be the same The focus of a design system is the optimum display of content. As Mark Boulton put it, designing “content out, not canvas in.” Chris Armstrong puts the emphasis on not designing for viewports but for content – “we need to build on what we do know: content.” In order to do this, we must share the same content across all devices and focus on how best to display and represent content through design system components. The practical: core visual components Typography first When you work with a lot of text content, typography is the easiest way to set the visual tone of the design across all viewport widths. It’s likely that you’ll choose one or two typefaces to use across the whole system, but you might change the most legible font size, balanced with the most comfortable measure, as the viewport width changes. Where typography meets layout The unit on which you choose to base the grid and layout design, font sizes and leading could be based on the typeface, an optimal reading size, or something more arbitrary. Sometimes I’ll choose a unit based on multiples of ten because it makes the maths in the CSS easier. Tim Brown suggests trying a modular scale. Chris Armstrong suggests basing it on your ideal measure, or the width of a fixed item of content such as an ad unit. Grids and layouts Sensible grid design can be a flexible yet solid foundation for your design system layout component. But you must be wary in responsive design that a grid might not work across all widths: even four columns could make for very cramped content and one-word measures on smaller screens. Maybe the grid columns are something you differentiate across widths, but you can keep the concept of the grid consistent. If the content has blocks in groups of three, you might decide on a three-column grid which folds down to one column for narrow viewports. If the grid focuses on the idea of symmetry and has a four-column grid on larger viewports, it might fold down to two columns for narrower viewports. These consistencies may seem subtle, not at all obvious to many except the designer, but it’s all these little constants and patterns across the whole of the design system that makes design decisions easier to make (as they adhere to the guiding concepts of your system), and give the product a uniform feel no matter what the device. Shape or form The shape or form components are concepts you already use in fixed-width web design for a strong, consistent look and feel. Since CSS border-radius became widely supported by browsers, a lot of designs feature circle themes. These are very distinctive and can be used across viewport widths giving them the same united feel, even if they’re not used in the same way. This could also apply to border styles, consistent shadows and any number of decorative details and textures. These are the elements that make up the shape or form of a design system. Colour Colour is the most basic way to reinforce a brand and unite experiences across viewports. The same hex colour used system-wide is instantly recognisable, no matter what the viewport width. The process While using a design system isn’t necessarily attached to any particular process, it does lend itself to some process ideals. Detaching design considerations from viewport widths A design system allows you to focus separately on the components that make up the system, disconnecting the look and feel from the layout. This helps prevent us getting stuck in the rut of the Apple breakpoints (brilliantly coined by Simon Foster) of mobile, tablet and desktop. It also forces us to design for variation in viewport experiences side by side, not one after the other. Design in the browser I can’t start off designing in the browser – it just doesn’t seem to bring out my creative side (and I’m incredibly envious of you if you can; I just have to start on paper) – but static mock-ups aren’t the only alternative. Style guides and style tiles are perfect for expressing the concepts of your design system. Pattern libraries could also work well. Mock-ups and breakpoints At some point, whether it’s to test your system ideas, or because a client needs help visualising how your system might work, you may end up producing some static mock-ups. It’s not the end of the world, but you must ensure that these consider all the viewports, not just those of the iDevices, or even the devices currently on the market. You need to decide the breakpoints where the states of your design change. The blocks within your content will always have optimum points for their display (based on their hierarchy, density, width, or type of interaction) and so your breakpoints should be based around these points. These are probably the ideal points at which to produce static mockups; treat them as snapshots. They’re not necessarily mock-ups, so much as a way of capturing how your design system would be interpreted when frozen at that particular viewport width. The future Creating design systems will give us the flexibility we need for working with the unknown devices of the future. It may be a change in process, but it shouldn’t be too much of a difference in thinking. The pioneers in responsive design have a hard job. Some of these problems may have already been solved in other technologies or industries, but it’s up to the pioneers to find those connections and help us formulate solutions and standards that will make responsive design the best it can possibly be. We need to keep experimenting and communicating, particularly in the area of design, as good user experiences are the true sign of whether our products are a success. 2012 Laura Kalbag laurakalbag 2012-12-12T00:00:00+00:00 https://24ways.org/2012/design-systems/ design
