{"rowid": 187, "title": "A New Year's Resolution", "contents": "The end of 2009 is fast approaching. Yet another year has passed in a split second. Our Web Designing careers are one year older and it\u2019s time to reflect on the highs and lows of 2009. What was your greatest achievement and what could you have done better? Perhaps, even more importantly, what are your goals for 2010?\n\nSomething that I noticed in 2009 is that being a web designer 24/7; it\u2019s easy to get consumed by the web. It\u2019s easy to get caught up in the blog posts, CSS galleries, web trends and Twitter! Living in this bubble can lead to one\u2019s work becoming stale, boring and basically like everyone else\u2019s work on the web. No designer wants this.\n\nSo, I say on 1st January 2010 let\u2019s make it our New Year\u2019s resolution to create something different, something special or even ground-breaking! Make it your goal to break the mold of current web design trends and light the way for your fellow web designer comrades!\n\nOf course I wouldn\u2019t let you embark on the New Year empty handed. To help you on your way I\u2019ve compiled a few thoughts and ideas to get your brains ticking!\n\nDon\u2019t design for the web, just design\n\nA key factor in creating something original and fresh for the web is to stop thinking in terms of web design. The first thing we need to do is forget the notion of headers, footers, side bars etc. A website doesn\u2019t necessarily need any of these, so even before we\u2019ve started we\u2019ve already limited our design possibilities by thinking in these very conventional and generally accepted web terms. The browser window is a 2D canvas like any other and we can do with it what we like. \n\nWith this in mind we can approach web design from a fresh perspective. We can take inspiration for web design from editorial design, packaging design, comics, poster design, album artwork, motion design, street signage and anything else you can think of. Web design is way more than the just the web and by taking this more wide angled view of what web design is and can be you\u2019ll find there are a thousand more exiting design possibilities.\n\nNote: Try leaving the wire framing till after you\u2019ve gone to town with some initial design concepts. You might find it helps keep your head out of that \u2018web space\u2019 a little bit longer, thus enabling you to think more freely about your design. Really go crazy with these as you can always pull it back into line later. The key is to think big initially and then work backwards. There\u2019s no point restricting your creativity early on because your technical knowledge can foresee problems down the line. You can always sort these problems out later on\u2026 let your creative juices flow!\n\n Inspiration can come from anywhere! (Photo: modomatic)\n\nTry something new!\n\nProgress in web design or in any design discipline is a sort of evolution. Design trends and solutions merge and mutate to create new design trends and hopefully better solutions. This is fine but the real leaps are made when someone has the guts to do something different. \n\nDon\u2019t be afraid to challenge the status quo. To create truly original work you have to be prepared to get it wrong and that\u2019s hard to do. When you\u2019re faced with this challenge just remind yourself that in web design there is rarely a \u2018best way to do something\u2019, or why would we ever do it any other way? \n\nIf you do this and get it right the pay off can be immense. Not only will you work stand out from the crowd by a mile, you will have become a trend setter as opposed to a trend follower.\n\nTell a story with your design\n\nGreat web design is way more than just the aesthetics, functionality or usability. Great web design goes beyond the pixels on the screen. For your website to make a real impact on it\u2019s users it has to connect with them emotionally. So, whether your website is promoting your own company or selling cheese it needs to move people. You need to weave a story into your design. It\u2019s this story that your users will connect with. \n\nTo do this the main ingredients of your design need to be strongly connected. In my head those main ingredients are Copy, Graphic Design, Typography, imagery and colour. \n\nCopy\n\nStrong meaningful copy is the backbone to most great web design work. Pay special attention to strap lines and headlines as these are often the sparks that start the fire. All the other elements can be inspired by this backbone of strong copy.\n\nGraphic Design\n\nUse the copy to influence how you treat the page with your graphic design. Let the design echo the words.\n\nTypography\n\nWhat really excites me about typography isn\u2019t the general text presentation on a page, most half decent web designer have a grasp of this already. What excites me is the potential there is to base a whole design on words and letters. Using the strong copy you already have, one has the opportunity the customise, distort, build and arrange words and letters to create beautiful and powerful compositions that can be the basis for an entire site design.\n\n Get creative with Typography (Photo: Pam Sattler)\n\nImagery and Colour\n\nWith clever use of imagery (photographs or illustrations) and colour you further have the chance to deepen the story you are weaving into your design. The key is to use meaningful imagery, don\u2019t to insert generic imagery for the sake of filling space\u2026 it\u2019s just a wasted opportunity.\n\nRemember, the main elements of your design combined are greater than the sum of their parts. Whatever design decisions you make on a page, make them for a good reason. It\u2019s not good enough to try and seduce your users with slick and shiny web pages. For your site to leave a lasting impression on the user you need to make that emotional connection.\n\n Telling the Story (Advertising Agency: Tita, Milano, Italy, Art Director: Emanuele Basso)\n\nGo one step further\n\nSo you\u2019ve almost finished your latest website design. You\u2019ve fulfilled the brief, you\u2019re happy with the result and you\u2019re pretty sure your client will be too. It\u2019s at this point we should ask ourselves \u201cCan I push this further\u201d? What touches could you add to the site that\u2019ll take it beyond what was required and into something exceptional? The truth is, to produce exceptional work we need to do more than is required of us. We need to answer the brief and then some!\n\nGo back through your site and make a note of what enhancements could be made to make the site not just good but outstanding. It might be revisiting a couple of pages that were neglected in the design process, it might be adding some CSS 3 gloss for the users that can benefit from it or it might just be adding some clever little easter eggs to show that you care. These touches will soon add up and make a massive difference to the finished product.\n\nSo, go one step further\u2026 take it further than you anyone else will. Then your work will stand out for sure.\n\nParting message\n\nI love being a designer for many of reasons but the main one being that with every new project we embark on we have the chance to express ourselves. We have the chance to create something special, something that people will talk about. It\u2019s this chance that drives us onwards day after day, year after year. So in 2010 shout louder than you ever have before, take chances, try something new and above all design your socks off!", "year": "2009", "author": "Mike Kus", "author_slug": "mikekus", "published": "2009-12-10T00:00:00+00:00", "url": "https://24ways.org/2009/a-new-years-resolution/", "topic": "business"} {"rowid": 170, "title": "A Pet Project is For Life, Not Just for Christmas", "contents": "I\u2019m excited: as December rolls on, I\u2019m winding down from client work and indulging in a big pet project I\u2019ve been dreaming up for quite some time, with the aim of releasing it early next year. I\u2019ve always been a bit of a sucker for pet projects and currently have a few in the works: the big one, two collaborations with friends, and my continuing (and completely un-web-related) attempt at music. But when I think about the other designers and developers out there whose work I admire, one thing becomes obvious: they\u2019ve all got pet projects! Look around the web and you\u2019ll see that anyone worth their salt has some sort of side project on the go. If you don\u2019t have yours yet, now\u2019s the time!\n\nHave a pet project to collaborate with your friends\n\nIt\u2019s not uncommon to find me staring at my screen, looking at beautiful websites my friends have made, grinning inanely because I feel so honoured to know such talented individuals. But one thing really frustrates me: I hardly ever get to work with these people! Sure, there are times when it\u2019s possible to do so, but due to various project situations, it\u2019s a rarity.\n\nSo, in order to work with my friends, I\u2019ve found the best way is to instigate the collaboration outside of client work; in other words, have a pet project together! Free from the hard realities of budgets, time restraints, and client demands, you and your friends can come up with something purely for your own pleasures. If you\u2019ve been looking for an excuse to work with other designers or developers whose work you love, the pet project is that excuse. They don\u2019t necessarily have to be friends, either: if the respect is mutual, it can be a great way of breaking the ice and getting to know someone. \n\n Figure 1: A forthcoming secret love-child from myself and Tim Van Damme\n\nHave a pet project to escape from your day job\n\nWe all like to moan about our clients and bosses, don\u2019t we? But if leaving your job or firing your evil client just isn\u2019t an option, why not escape from all that and pour your creative energies into something you genuinely enjoy? \n\nIt\u2019s not just about reacting to negativity, either: a pet project is a great way to give yourself a bit of variety. As web designers, our day-to-day work forces us to work within a set of web-related contraints and sometimes it can be demoralising to spend so many hours fixing IE bugs. The perfect antidote? Go and do some print design! If it\u2019s not possible in your day job or client work, the pet project is the perfect place to exercise your other creative muscles. Yes, print design (or your chosen alternative) has its own constraints, but if they\u2019re different to those you experience on a daily basis, it\u2019ll be a welcome relief and you\u2019ll return to your regular work feeling refreshed.\n\n Figure 2: Ligature, Loop & Stem, from Scott Boms & Luke Dorny\n\nHave a pet project to fulfill your own needs\n\nMany pet projects come into being because the designers and/or developers behind them are looking for a tool to accomplish a task and find that it doesn\u2019t exist, thus prompting them to create their own solution. In fact, the very app I\u2019m using to write this article \u2014 Ommwriter, from Herraiz Soto & Co \u2014 was originally a tool they\u2019d created for their internal staff, before releasing it to the public so that it could be enjoyed by others.\n\nJust last week, Tina Roth Eisenberg launched Teux Deux, a pet project she\u2019d designed to meet her own requirements for a to-do list, having found that no existing apps fulfilled her needs. Oh, and it was a collaboration with her studio mate Cameron. Remember what I was saying about working with your friends?\n\n Figure 3: Teux Deux, the GTD pet project that launched just last week\n\nHave a pet project to help people out\n\nOmmwriter and Teux Deux are free for anyone to use. Let\u2019s just think about that for a moment: the creators have invested their time and effort in the project, and then given it away to be used by others. That\u2019s very cool and something we\u2019re used to seeing a lot of in the web community (how lucky we are)! People love free stuff and giving away the fruits of your labour will earn you major kudos. Of course, there\u2019s nothing wrong with making some money, either \u2014 more on that in a second.\n\n Figure 4: Dan Rubin\u2018s extremely helpful Make Photoshop Faster\n\nHave a pet project to raise your profile\n\nSo, giving away free stuff earns you kudos. And kudos usually helps you raise your profile in the industry. We all like a bit of shameless fame, don\u2019t we? But seriously, if you want to become well known, make something cool. It could be free (to buy you the love and respect of the community) or it could be purchasable (if you\u2019ve made something that\u2019s cool enough to deserve hard-earned cash), but ultimately it needs to be something that people will love. \n\n Figure 5: Type designer Jos Buivenga has shot to fame thanks to his beautiful typefaces and \u2018freemium\u2019 business model\n\nIf you\u2019re a developer with no design skills, team up with a good designer so that the design community appreciate its aesthetic. If you\u2019re a designer with no development skills, team up with a good developer so that it works. Oh, and not that I\u2019d recommend you ever do this for selfish reasons, but collaborating with someone you admire \u2014 whose work is well-respected by the community \u2014 will also help raise your profile.\n\nHave a pet project to make money\n\nIn spite of our best hippy-esque intentions to give away free stuff to the masses, there\u2019s also nothing wrong with making a bit of money from your pet project. In fact, if your project involves you having to make a considerable financial investment, it\u2019s probably a good idea to try and recoup those costs in some way.\n\n Figure 6: The success of Shaun Inman\u2018s various pet projects \u2014 Mint, Fever, Horror Vacui, etc. \u2014 have allowed him to give up client work entirely.\n\nA very common way to do that in both the online and offline worlds is to get some sort of advertising. For a slightly different approach, try contacting a company who are relevant to your audience and ask them if they\u2019d be interesting in sponsoring your project, which would usually just mean having their brand associated with yours in some way. This is still a form of advertising but tends to allow for a more tasteful implementation, so it\u2019s worth pursuing. \n\nAdvertising is a great way to cover your own costs and keep things free for your audience, but when costs are considerably higher (like if you\u2019re producing a magazine with high production values, for instance), there\u2019s nothing wrong with charging people for your product. But, as I mentioned above, you\u2019ve got to be positive that it\u2019s worth paying for!\n\nHave a pet project just for fun\n\nSometimes there\u2019s a very good reason for having a pet project \u2014 and sometimes even a viable business reason \u2014 but actually you don\u2019t need any reason at all. Wanting to have fun is just as worthy a motivation, and if you\u2019re not going to have fun doing it, then what\u2019s the point? Assuming that almost all pet projects are designed, developed, written, printed, marketed and supported in our free time, why not do something enjoyable?\n\n Figure 7: Jessica Hische\u2018s beautiful Daily Drop Cap\n\nIn conclusion\n\nThe fact that you\u2019re reading 24 ways shows that you have a passion for the web, and that\u2019s something I\u2019m happy to see in abundance throughout our community. Passion is a term that\u2019s thrown about all over the place, but it really is evident in the work that people do. It\u2019s perhaps most evident, however, in the pet projects that people create. Don\u2019t forget that the very site you\u2019re reading this article on is\u2026 a pet project.\n\nIf you\u2019ve yet to do so, make it a new year\u2019s resolution for 2010 to have your own pet project so that you can collaborate with your friends, escape from your day job, fulfil your own needs, help people out, raise your profile, make money, and \u2014 above all \u2014 have fun.", "year": "2009", "author": "Elliot Jay Stocks", "author_slug": "elliotjaystocks", "published": "2009-12-18T00:00:00+00:00", "url": "https://24ways.org/2009/a-pet-project-is-for-life-not-just-for-christmas/", "topic": "business"} {"rowid": 182, "title": "Breaking Out The Edges of The Browser", "contents": "HTML5 contains more than just the new entities for a more meaningful document, it also contains an arsenal of JavaScript APIs. So many in fact, that some APIs have outgrown the HTML5 spec\u2019s backyard and have been sent away to grow up all on their own and been given the prestigious honour of being specs in their own right.\n\nSo when I refer to (bendy finger quote) \u201cHTML5\u201d, I mean the HTML5 specification and a handful of other specifications that help us authors build web applications.\n\nExamples of those specs I would include in the umbrella term would be: geolocation, web storage, web databases, web sockets and web workers, to name a few.\n\nFor all you guys and gals, on this special 2009 series of 24 ways, I\u2019m just going to focus on data storage and offline applications: boldly taking your browser where no browser has gone before!\n\nWeb Storage\n\nThe Web Storage API is basically cookies on steroids, a unhealthy dosage of steroids. Cookies are always a pain to work with. First of all you have the problem of setting, changing and deleting them. Typically solved by Googling and blindly relying on PPK\u2019s solution. If that wasn\u2019t enough, there\u2019s the 4Kb limit that some of you have hit when you really don\u2019t want to.\n\nThe Web Storage API gets around all of the hoops you have to jump through with cookies. Storage supports around 5Mb of data per domain (the spec\u2019s recommendation, but it\u2019s open to the browsers to implement anything they like) and splits in to two types of storage objects:\n\n\n\tsessionStorage \u2013 available to all pages on that domain while the window remains open\n\tlocalStorage \u2013 available on the domain until manually removed\n\n\nSupport\n\nIgnoring beta browsers for our support list, below is a list of the major browsers and their support for the Web Storage API:\n\n\n\tLatest: Internet Explorer, Firefox, Safari (desktop & mobile/iPhone)\n\tPartial: Google Chrome (only supports localStorage)\n\tNot supported: Opera (as of 10.10)\n\n\nUsage\n\nBoth sessionStorage and localStorage support the same interface for accessing their contents, so for these examples I\u2019ll use localStorage.\n\nThe storage interface includes the following methods:\n\n\n\tsetItem(key, value)\n\tgetItem(key)\n\tkey(index)\n\tremoveItem(key)\n\tclear()\n\n\nIn the simple example below, we\u2019ll use setItem and getItem to store and retrieve data:\n\nlocalStorage.setItem('name', 'Remy');\nalert( localStorage.getItem('name') );\n\nUsing alert boxes can be a pretty lame way of debugging. Conveniently Safari (and Chrome) include database tab in their debugging tools (cmd+alt+i), so you can get a visual handle on the state of your data:\n\n Viewing localStorage\n\nAs far as I know only Safari has this view on stored data natively in the browser. There may be a Firefox plugin (but I\u2019ve not found it yet!) and IE\u2026 well that\u2019s just IE.\n\nEven though we\u2019ve used setItem and getItem, there\u2019s also a few other ways you can set and access the data.\n\nIn the example below, we\u2019re accessing the stored value directly using an expando and equally, you can also set values this way:\n\nlocalStorage.name = \"Remy\";\nalert( localStorage.name ); // shows \"Remy\"\n\nThe Web Storage API also has a key method, which is zero based, and returns the key in which data has been stored. This should also be in the same order that you set the keys, for example:\n\nalert( localStorage.getItem(localStorage.key(0)) ); \n// shows \"Remy\"\n\nI mention the key() method because it\u2019s not an unlikely name for a stored value. This can cause serious problems though.\n\nWhen selecting the names for your keys, you need to be sure you don\u2019t take one of the method names that are already on the storage object, like key, clear, etc. As there are no warnings when you try to overwrite the methods, it means when you come to access the key() method, the call breaks as key is a string value and not a function.\n\nYou can try this yourself by creating a new stored value using localStorage.key = \"foo\" and you\u2019ll see that the Safari debugger breaks because it relies on the key() method to enumerate each of the stored values.\n\nUsage Notes\n\nCurrently all browsers only support storing strings. This also means if you store a numeric, it will get converted to a string:\n\nlocalStorage.setItem('count', 31);\nalert(typeof localStorage.getItem('count')); \n// shows \"string\"\n\nThis also means you can\u2019t store more complicated objects natively with the storage objects. To get around this, you can use Douglas Crockford\u2019s JSON parser (though Firefox 3.5 has JSON parsing support baked in to the browser \u2013 yay!) json2.js to convert the object to a stringified JSON object:\n\nvar person = {\n\tname: 'Remy',\n\theight: 'short',\n\tlocation: 'Brighton, UK'\n};\nlocalStorage.setItem('person', JSON.stringify(person));\nalert( JSON.parse(localStorage.getItem('person')).name ); \n// shows \"Remy\"\n\nAlternatives\n\nThere are a few solutions out there that provide storage solutions that detect the Web Storage API, and if it\u2019s not available, fall back to different technologies (for instance, using a flash object to store data). One comprehensive version of this is Dojo\u2019s storage library. I\u2019m personally more of a fan of libraries that plug missing functionality under the same namespace, just as Crockford\u2019s JSON parser does (above).\n\nFor those interested it what that might look like, I\u2019ve mocked together a simple implementation of sessionStorage. Note that it\u2019s incomplete (because it\u2019s missing the key method), and it could be refactored to not using the JSON stringify (but you would need to ensure that the values were properly and safely encoded):\n\n// requires json2.js for all browsers other than Firefox 3.5\nif (!window.sessionStorage && JSON) {\n\twindow.sessionStorage = (function () {\n\t\t// window.top.name ensures top level, and supports around 2Mb\n\t\tvar data = window.top.name ? JSON.parse(window.top.name) : {};\n\t\treturn { \n\t\t\tsetItem: function (key, value) {\n\t\t\t\tdata[key] = value+\"\"; // force to string\n\t\t\t\twindow.top.name = JSON.stringify(data);\n\t\t\t},\n\t\t\tremoveItem: function (key) {\n\t\t\t\tdelete data[key];\n\t\t\t\twindow.top.name = JSON.stringify(data); \n\t\t\t},\n\t\t\tgetItem: function (key) {\n\t\t\t\treturn data[key] || null;\n\t\t\t},\n\t\t\tclear: function () {\n\t\t\t\tdata = {};\n\t\t\t\twindow.top.name = '';\n\t\t\t}\n\t\t};\n\t})();\n}\n\nNow that we\u2019ve cracked the cookie jar with our oversized Web Storage API, let\u2019s have a look at how we take our applications offline entirely.\n\nOffline Applications\n\nOffline applications is (still) part of the HTML5 specification. It allows developers to build a web app and have it still function without an internet connection. The app is access via the same URL as it would be if the user were online, but the contents (or what the developer specifies) is served up to the browser from a local cache. From there it\u2019s just an everyday stroll through open web technologies, i.e. you still have access to the Web Storage API and anything else you can do without a web connection.\n\nFor this section, I\u2019ll refer you to a prototype demo I wrote recently of a contrived Rubik\u2019s cube (contrived because it doesn\u2019t work and it only works in Safari because I\u2019m using 3D transforms).\n\n Offline Rubik\u2019s cube\n\nSupport\n\nSupport for offline applications is still fairly limited, but the possibilities of offline applications is pretty exciting, particularly as we\u2019re seeing mobile support and support in applications such as Fluid (and I would expect other render engine wrapping apps).\n\nSupport currently, is as follows:\n\n\n\tLatest: Safari (desktop & mobile/iPhone)\n\tSort of: Firefox\u2021\n\tNot supported: Internet Explorer, Opera, Google Chrome\n\n\n\u2021 Firefox 3.5 was released to include offline support, but in fact has bugs where it doesn\u2019t work properly (certainly on the Mac), Minefield (Firefox beta) has resolved the bug.\n\nUsage\n\nThe status of the application\u2019s cache can be tested from the window.applicationCache object. However, we\u2019ll first look at how to enable your app for offline access.\n\nYou need to create a manifest file, which will tell the browser what to cache, and then we point our web page to that cache:\n\n\n\n\n\nFor the manifest to be properly read by the browser, your server needs to serve the .manifest files as text/manifest by adding the following to your mime.types:\n\ntext/cache-manifest manifest\n\nNext we need to populate our manifest file so the browser can read it:\n\nCACHE MANIFEST\n/demo/rubiks/index.html\n/demo/rubiks/style.css\n/demo/rubiks/jquery.min.js\n/demo/rubiks/rubiks.js\n# version 15\n\nThe first line of the manifest must read CACHE MANIFEST. Then subsequent lines tell the browser what to cache.\n\nThe HTML5 spec recommends that you include the calling web page (in my case index.html), but it\u2019s not required. If I didn\u2019t include index.html, the browser would cache it as part of the offline resources.\n\nThese resources are implicitly under the CACHE namespace (which you can specify any number of times if you want to).\n\nIn addition, there are two further namespaces: NETWORK and FALLBACK.\n\nNETWORK is a whitelist namespace that tells the browser not to cache this resource and always try to request it through the network.\n\nFALLBACK tells the browser that whilst in offline mode, if the resource isn\u2019t available, it should return the fallback resource.\n\nFinally, in my example I\u2019ve included a comment with a version number. This is because once you include a manifest, the only way you can tell the browser to reload the resources is if the manifest contents changes. So I\u2019ve included a version number in the manifest which I can change forcing the browser to reload all of the assets.\n\nHow it works\n\nIf you\u2019re building an app that makes use of the offline cache, I would strongly recommend that you add the manifest last. The browser implementations are very new, so can sometimes get a bit tricky to debug since once the resources are cached, they really stick in the browser.\n\nThese are the steps that happen during a request for an app with a manifest:\n\n\n\tBrowser: sends request for your app.html\n\tServer: serves all associated resources with app.html \u2013 as normal\n\tBrowser: notices that app.html has a manifest, it re-request the assets in the manifest\n\tServer: serves the requested manifest assets (again)\n\tBrowser: window.applicationCache has a status of UPDATEREADY\n\tBrowser: reloads\n\tBrowser: only request manifest file (which doesn\u2019t show on the net requests panel)\n\tServer: responds with 304 Not Modified on the manifest file\n\tBrowser: serves all the cached resources locally\n\n\nWhat might also add confusion to this process, is that the way the browsers work (currently) is if there is a cache already in place, it will use this first over updated resources. So if your manifest has changed, the browser will have already loaded the offline cache, so the user will only see the updated on the next reload. \n\nThis may seem a bit convoluted, but you can also trigger some of this manually through the applicationCache methods which can ease some of this pain.\n\nIf you bind to the online event you can manually try to update the offline cache. If the cache has then updated, swap the updated resources in to the cache and the next time the app loads it will be up to date. You could also prompt your user to reload the app (which is just a refresh) if there\u2019s an update available.\n\nFor example (though this is just pseudo code):\n\naddEvent(applicationCache, 'updateready', function () {\n\tapplicationCache.swapCache();\n\ttellUserToRefresh();\n});\naddEvent(window, 'online', function () {\n\tapplicationCache.update();\n});\n\nBreaking out of the Browser\n\nSo that\u2019s two different technologies that you can use to break out of the traditional browser/web page model and get your apps working in a more application-ny way.\n\nThere\u2019s loads more in the HTML5 and non-HTML5 APIs to play with, so take your Christmas break to check them out!", "year": "2009", "author": "Remy Sharp", "author_slug": "remysharp", "published": "2009-12-02T00:00:00+00:00", "url": "https://24ways.org/2009/breaking-out-the-edges-of-the-browser/", "topic": "code"} {"rowid": 192, "title": "Cleaner Code with CSS3 Selectors", "contents": "The parts of CSS3 that seem to grab the most column inches on blogs and in articles are the shiny bits.

However what really gets me, as a developer, excited is a bit more mundane. \n\nIn this article I\u2019m going to take a look at some of the ways our front and back-end code will be simplified by CSS3, by looking at the ways we achieve certain visual effects now in comparison to how we will achieve them in a glorious, CSS3-supported future. I\u2019m also going to demonstrate how we can use these selectors now with a little help from JavaScript \u2013 which can work out very useful if you find yourself in a situation where you can\u2019t change markup that is being output by some server-side code.\n\nThe wonder of nth-child\n\nSo why does nth-child get me so excited? Here is a really common situation, the designer would like the tables in the application to look like this:\n\n\n\nSetting every other table row to a different colour is a common way to enhance readability of long rows. The tried and tested way to implement this is by adding a class to every other row. If you are writing the markup for your table by hand this is a bit of a nuisance, and if you stick a row in the middle you have to change the rows the class is applied to. If your markup is generated by your content management system then you need to get the server-side code to add that class \u2013 if you have access to that code.\n\n\n\n\nStriping every other row - using classes\n\n\n\n\t\n\t\t\n\t\t\t\n\t\t\t\n\t\t\t\n\t\t\t\n\t\t\n\t\t\n\t\t\t\n\t\t\t\n\t\t\t\n\t\t\t\n\t\t\n\t\t\n\t\t\t\n\t\t\t\n\t\t\t\n\t\t\t\n\t\t\n\t\t\n\t\t\t\n\t\t\t\n\t\t\t\n\t\t\t\n\t\t\n\t\t\n\t\t\t\n\t\t\t\n\t\t\t\n\t\t\t\n\t\t\n\t

\n\n\n\nView Example 1\n\nThis situation is something I deal with on almost every project, and apart from being an extra thing to do, it just isn\u2019t ideal having the server-side code squirt classes into the markup for purely presentational reasons. This is where the nth-child pseudo-class selector comes in. The server-side code creates a valid HTML table for the data, and the CSS then selects the odd rows with the following selector:\n\ntr:nth-child(odd) td {\n\tbackground-color: #86B486;\n}\n\nView Example 2\n\nThe odd and even keywords are very handy in this situation \u2013 however you can also use a multiplier here. 2n would be equivalent to the keyword \u2018odd\u2019 3n would select every third row and so on.\n\nBrowser support\n\nSadly, nth-child has pretty poor browser support. It is not supported in Internet Explorer 8 and has somewhat buggy support in some other browsers. Firefox 3.5 does have support. In some situations however, you might want to consider using JavaScript to add this support to browsers that don\u2019t have it. This can be very useful if you are dealing with a Content Management System where you have no ability to change the server-side code to add classes into the markup.\n\nI\u2019m going to use jQuery in these examples as it is very simple to use the same CSS selector used in the CSS to target elements with jQuery \u2013 however you could use any library or write your own function to do the same job. In the CSS I have added the original class selector to the nth-child selector:\n\ntr:nth-child(odd) td, tr.odd td {\n\tbackground-color: #86B486;\n}\n\nThen I am adding some jQuery to add a class to the markup once the document has loaded \u2013 using the very same nth-child selector that works for browsers that support it. \n\n \n \n\nView Example 3\n\nWe could just add a background colour to the element using jQuery, however I prefer not to mix that information into the JavaScript as if we change the colour on our table rows I would need to remember to change it both in the CSS and in the JavaScript.\n\nDoing something different with the last element\n\nSo here\u2019s another thing that we often deal with. You have a list of items all floated left with a right hand margin on each element constrained within a fixed width layout. If each element has the right margin applied the margin on the final element will cause the set to become too wide forcing that last item down to the next row as shown in the below example where I have used a grey border to indicate the fixed width.\n\n\n\nCurrently we have two ways to deal with this. We can put a negative right margin on the list, the same width as the space between the elements. This means that the extra margin on the final element fills that space and the item doesn\u2019t drop down. \n\n\n\n\nThe last item is different\n\n\n\n\t
\n\t\t\n\t
\n\n\n\nView Example 4\n\nThe other solution will be to put a class on the final element and in the CSS remove the margin for this class. \n\nul.gallery li.last {\n\tmargin-right: 0;\n}\n\nThis second solution may not be easy if the content is generated from server-side code that you don\u2019t have access to change.\n\nIt could all be so different. In CSS3 we have marvellously common-sense selectors such as last-child, meaning that we can simply add rules for the last list item. \n\nul.gallery li:last-child {\n\tmargin-right: 0;\n}\n\nView Example 5\n\nThis removed the margin on the li which is the last-child of the ul with a class of gallery. No messing about sticking classes on the last item, or pushing the width of the item out wit a negative margin.\n\nIf this list of items repeated ad infinitum then you could also use nth-child for this task. Creating a rule that makes every 3rd element margin-less.\n\nul.gallery li:nth-child(3n) {\n\tmargin-right: 0;\n}\n\nView Example 6\n\n\n\nA similar example is where the designer has added borders to the bottom of each element \u2013 but the last item does not have a border or is in some other way different. Again, only a class added to the last element will save you here if you cannot rely on using the last-child selector.\n\nBrowser support for last-child\n\nThe situation for last-child is similar to that of nth-child, in that there is no support in Internet Explorer 8. However, once again it is very simple to replicate the functionality using jQuery. Adding our .last class to the last list item.\n\n$(\"ul.gallery li:last-child\").addClass(\"last\");\n\nWe could also use the nth-child selector to add the .last class to every third list item.\n\n$(\"ul.gallery li:nth-child(3n)\").addClass(\"last\");\n\nView Example 7\n\nFun with forms\n\nStyling forms can be a bit of a trial, made difficult by the fact that any CSS applied to the input element will effect text fields, submit buttons, checkboxes and radio buttons. As developers we are left adding classes to our form fields to differentiate them. In most builds all of my text fields have a simple class of text whereas I wouldn\u2019t dream of adding a class of para to every paragraph element in a document.\n\n\n\n\nSyling form fields\n\n\n\n\t

\n\n\n\nView Example 8\n\nAttribute selectors provide a way of targeting elements by looking at the attributes of those elements. Unlike the other examples in this article which are CSS3 selectors, the attribute selector is actually a CSS2.1 selector \u2013 it just doesn\u2019t get much use because of lack of support in Internet Explorer 6. Using attribute selectors we can write rules for text inputs and form buttons without needing to add any classes to the markup. For example after removing the text and button classes from my text and submit button input elements I can use the following rules to target them:\n\nform input[type=\"text\"] {\n border: 1px solid #333;\n padding: 0.2em;\n width: 400px;\n}\nform input[type=\"submit\"]{\n border: 1px solid #333;\n background-color: #eee;\n color: #000;\n padding: 0.1em;\n} \n\nView Example 9\n\nAnother problem that I encounter with forms is where I am using CSS to position my labels and form elements by floating the labels. This works fine as long as I want all of my labels to be floated, however sometimes we get a set of radio buttons or a checkbox, and I don\u2019t want the label field to be floated. As you can see in the below example the label for the checkbox is squashed up into the space used for the other labels, yet it makes more sense for the checkbox to display after the text.\n\n\n\nI could use a class on this label element however CSS3 lets me to target the label attribute directly by looking at the value of the for attribute.\n\nlabel[for=\"fOptIn\"] {\n float: none;\n width: auto;\n}\n\n\n\nBeing able to precisely target attributes in this way is incredibly useful, and once IE6 is no longer an issue this will really help to clean up our markup and save us from having to create all kinds of special cases when generating this markup on the server-side.\n\nBrowser support\n\nThe news for attribute selectors is actually pretty good with Internet Explorer 7+, Firefox 2+ and all other modern browsers all having support. As I have already mentioned this is a CSS2.1 selector and so we really should expect to be able to use it as we head into 2010! Internet Explorer 7 has slightly buggy support and will fail on the label example shown above however I discovered a workaround in the Sitepoint CSS reference comments. Adding the selector label[htmlFor=\"fOptIn\"] to the correct selector will create a match for IE7.\n\nIE6 does not support these selector but, once again, you can use jQuery to plug the holes in IE6 support. The following jQuery will add the text and button classes to your fields and also add a checks class to the label for the checkbox, which you can use to remove the float and width for this element.\n\n$('form input[type=\"submit\"]').addClass(\"button\");\n$('form input[type=\"text\"]').addClass(\"text\");\n$('label[for=\"fOptIn\"]').addClass(\"checks\");\n\nView Example 10\n\nThe selectors I\u2019ve used in this article are easy to overlook as we do have ways to achieve these things currently. As developers \u2013 especially when we have frameworks and existing code that cope with these situations \u2013 it is easy to carry on as we always have done. \n\nI think that the time has come to start to clean up our front and backend code and replace our reliance on classes with these more advanced selectors. With the help of a little JavaScript almost all users will still get the full effect and, where we are dealing with purely visual effects, there is definitely a case to be made for not worrying about the very small percentage of people with old browsers and no JavaScript.

Thanks to the hard work of Jeffrey, Andy, Andy, Cameron, Colly, Dan and many others, learning how to decently markup a website and write lightweight stylesheets was surprisingly easy. They made it so easy even a complete idiot (OH HAI) was able to quickly master it.\n\nAnd then\u2026 nothing. For a long time, it seemed like there wasn\u2019t happening anything in the land of CSS, time stood still. Once you knew the basics, there wasn\u2019t anything new to keep up with. It looked like a great band split, but people just kept re-releasing their music in various \u201cBest Of!\u201d or \u201cRemastered!\u201d albums.\n\nFast forward a couple of years to late 2006. On the official WebKit blog Surfin\u2019 Safari, there\u2019s an article about something called CSS animations. Great new stuff to play with, but only supported by nightly builds (read: very, very beta) of WebKit. In the following months, they release other goodies, like CSS gradients, CSS reflections, CSS masks, and even more CSS animation sexiness. Whoa, looks like the band got back together, found their second youth, and went into overdrive! The problem was that if you wanted to listen to their new albums, you had to own some kind of new high-tech player no one on earth (besides some early adopters) owned.\n\nBack in the time machine. It is now late 2009, close to Christmas. Things have changed. Browsers supporting these new toys are widely available left and right. Even non-techies are using these advanced browsers to surf the web on a daily basis!\n\nEpic win? Almost, but at least this gives us enough reason to start learning how we could use all this new CSS voodoo. On Monday, Natalie Downe showed you a good tutorial on Going Nuts with CSS Transitions. Today, I\u2019m taking it one step further\u2026\n\nHowto: A basic spinner\n\nNo matter how fast internet tubes or servers are, we\u2019ll always need spinners to indicate something\u2019s happening behind the scenes. Up until now, people would go to some site, pick one of the available templates, customize their foreground and background colors, and download a beautiful GIF image.\n\nThere are some downsides to this though:\n\n\n\tIt\u2019s only _semi_-transparent: If you change your mind and pick a slightly different background color, you need to go back to the site, set all the parameters again, and replace your current image. There isn\u2019t even a way to pick an image or gradient as background.\n\tLimited number of frames, probable to keep the file-size as small as possible (don\u2019t forget this thing needs to be loaded before whatever process is finished in the background), and you don\u2019t have that 24 frames per second smoothness.\n\tThis is just too fucking easy. As a front-end code geek, there must be a \u201ccooler\u201d way to do this!\n\n\nWhat do we need to make a spinner with CSS animations? One image, and one element on our webpage we can hook on to. Yes, that\u2019s it. I created a simple transparent PNG that looks it might be a spinner, and for the element on the page, I wrote this piece of genius HTML:\n\n

Please wait while we do what we do best.

\n\nLooks semantic enough to me! Here\u2019s the basic HTML I\u2019m using to position the element in the center of the screen, and make the text inside it disappear:\n\n#spinner {\n\tposition: absolute;\n\ttop: 50%;\n\tleft: 50%;\n\tmargin: -100px 0 0 -100px;\n\theight: 200px;\n\twidth: 200px;\n\ttext-indent: 250px;\n\twhite-space: nowrap;\n\toverflow: hidden;\n}\n\nCool, but now we don\u2019t see anything. Let\u2019s pull rabbit number one out of the hat: -webkit-mask-image (accompanied by the previously mentioned transparent PNG image):\n\n#spinner {\n\t...\n\t-webkit-mask-image: url(../img/spinner.png);\n}\n\nBy now you should be feeling like a magician already. Oh, wait, we still have a blank screen, looks like we left something in the hat (tip: not rabbit droppings):\n\n#spinner {\n\t...\n\t-webkit-mask-image: url(../img/spinner.png);\n\tbackground-color: #000;\n}\n\nNice! What we\u2019ve done right here is telling the element to clip onto the PNG. It\u2019s a lot like clipping layers in Photoshop. So, spinners, they move, right? Into the hat again, and look what we pull out this time: CSS animations!\n\n#spinner {\n\t...\n\t-webkit-mask-image: url(../img/spinner.png);\n\tbackground-color: #000;\n\t-webkit-animation-name: spinnerRotate;\n\t-webkit-animation-duration: 2s;\n\t-webkit-animation-iteration-count: infinite;\n\t-webkit-animation-timing-function: linear;\n}\n\nSome explanation:\n\n\n\t-webkit-animation-name: Name of the animation we\u2019ll be defining later.\n\t-webkit-animation-duration: The timespan of the animation.\n\t-webkit-animation-iteration-count: Repeat once, a defined number of times or infinitely?\n\t-webkit-animation-timing-function: Linear is the one you\u2019ll be using mostly. Other options are ease-in, ease-out, ease-in-out\u2026\n\n\nLet\u2019s define spinnerRotate:\n\n@-webkit-keyframes spinnerRotate {\n\tfrom {\n\t\t-webkit-transform:rotate(0deg);\n\t}\n\tto {\n\t\t-webkit-transform:rotate(360deg);\n\t}\n}\n\nEn Anglais: Rotate #spinner starting at 0 degrees, ending at 360 degrees, over a timespan of 2 seconds, at a constant speed, and keep repeating this animation forever.\n\nThat\u2019s it! See it in action on the demo page.\n\nNote: these examples only work when you\u2019re using a WebKit-based browser like Safari, Mobile Safari or Google Chrome. I\u2019m confident though that Mozilla and Opera will try their very best catching up with all this new CSS goodness soon.\n\nWhen looking at this example, you see the possibilities are endless. Another advantage is you can change the look of it entirely by only changing a couple of lines of CSS, instead of re-creating and re-downloading the image from some website smelling like web 2.0 gone bad. I made another demo that shows how great it is to be able to change background and foreground colors (even on the fly!).\n\nSo there you have it, a smoothly animated, fully transparent and completely customizable spinner. Cool? I think so. (Ladies?)\n\nBut you can do a lot more with CSS animations than just create pretty spinners. Since I was fooling around with it anyway, I decided to test how far you can push this, space is the final limit, right?\n\nConclusion\n\nCSS has never been more exciting than it is right now. I\u2019m even prepared to say CSS is \u201ccool\u201d again, both for the more experienced front-end developers as for the new designers discovering CSS every day now.\n\nBut\u2026\n\nRemember when Javascript became popular? Remember when Flash became popular? Every time we\u2019re been given new toys, some people aren\u2019t ashamed to use it in a way you can barely call constructive. I\u2019m thinking of Geocities websites, loaded with glowing blocks of text, moving images, bad color usage\u2026 In the wise words of Stan Lee: With great power there must also come great responsibility!

Yes, you heard me correctly. Think about it: our computers come with web fonts already installed; fonts that have been designed specifically to work well online and at small size; and fonts that we can be sure other people have too. \n\nYes, we\u2019ve been spoilt. We don\u2019t need to think about using Verdana, Arial, Georgia or Cambria. \n\nYet, for a long time now, designers have felt we needed more. We want to choose whatever typeface we feel necessary for our designs. We did bad things along the way in pursuit of this goal such as images for text. Smart people dreamt up tools to help us such as sIFR, or Cuf\u00f3n. Only fairly recently, @font-face is supported in most browsers. The floodgates are opening. It really is the dawn of a new typographic era on the web. And we must tread carefully. \n\nThe New Typesetters \n\nMany years ago, before the advent of desktop publishing, if you wanted words set in a particular typeface, you had to go to a Typesetter. A Typesetter, or Compositor, as they were sometimes called, was a person whose job it was to take the written word (in the form of a document or manuscript) and \u2018set\u2019 the type in the desired typeface. The designer would chose what typeface they wanted \u2013 and all the ligatures, underlines, italics and whatnot \u2013 and then scribble all over the manuscript so the typesetter could set the correct type. \n\nThen along came Desktop Publishing and every Tom, Dick and Harry could choose type on their computer and an entire link in the typographic chain was removed within just a few years. Well, that\u2019s progress I guess. That was until six months ago when Typesetting was reborn on the web in the guise of a font service: Typekit. \n\nTypekit \u2013 and services like Typekit such as Typotheque, Kernest and the upcoming Fontdeck \u2013 are typesetting services for the web. You supply them with your content, in the form of a webpage, and they provide you with some JavaScript to render that webpage in the typeface you\u2019ve specified simply by adding the font name in your CSS file. \n\nThanks to services like these, font foundries are now talking to create licensing structures to allow us to embed fonts into our web pages legally \u2013 which has always been a sticking point in the past. So, finally, us designers can get what we want: whatever typeface we want on the web. \n\nYes, but\u2026 there are hurdles. One of which is the subject of this article. \n\nThe differences between Web Fonts and other fonts \n\nWeb fonts are different to normal fonts. They differ in a whole bunch of ways, from loose letter spacing to larger x-heights. But perhaps the most notable practical difference is file size. Let\u2019s take a look at one of Typekit\u2019s latest additions from the FontFont library, Meta. \n\nMeta Roman weighs in at 42 KB. This is a fairly typical file size for a single weight of a good font. Now, let\u2019s have a look at Verdana. Verdana is 186 KB. For one weight. The four weight family for Verdana weighs in at 686 KB. Four weights for half a megabyte!? Why so huge? \n\nWell, Verdana has a lot of information packed into its 186 KB. It has the largest hinting data table of any typeface (the information carried by a font that tells it how to align itself to the pixels on your screen). As it has been shipped with Microsoft products since 1996, it has had time to grow to support many, many languages. Along with its cousin, Georgia (283 KB), Verdana was a new breed of typeface. And it\u2019s grown fat. \n\nIf really serious web typography takes off \u2013 and by that I mean typefaces specifically designed for the screen \u2013 then we\u2019re going to see more fonts increase in file size as the font files include more data. So, if you\u2019re embedding a font weighing in at 100 KB, what happens? \n\nThe Flash of Unstyled Text \n\nWe all remember the Flash of Unstyled Content bug on Internet Explorer, right? That annoying bug that caused a momentary flash of unstyled HTML page. Well, the same thing can happen with embedding fonts using @font-face. An effect called The Flash of Unstyled Text (FOUT), first coined by Paul Irish. Personally, I prefer to call it the Flash of UnTypeset Text (still FOUT), as the text is styled, just not with what you want. \n\nIf you embed a typeface in your CSS, then the browser will download that typeface. Typically, browsers differ in the way they handle this procedure. \n\nFirefox and Opera will render the text using the next font in your font stack until the first (embedded) font is loaded. It will then switch to the embedded font. \n\nWebkit takes the approach that you asked for that font so it will wait until it\u2019s completely loaded before showing it you. \n\nIn Opera and Firefox, you get a FOUT. In Webkit, you don\u2019t. You wait. \n\nHang on there. Didn\u2019t I say that good web fonts weigh in considerably more than \u2018normal\u2019 fonts? And whilst the browser is downloading the font, the user gets what to look at? Some pictures, background colours and whatever else isn\u2019t HTML? I believe Webkit\u2019s handling of font embedding \u2013 as deliberate as it is \u2013 is damaging to the practice of font embedding. Why? Well, we can design to a switch in typeface (as jarring as that is for the user), but we can\u2019t design to blank space. \n\nLet\u2019s have a closer look at how we can design to FOUT. \n\nMore considered font stacks \n\nWe all know that font stacks in CSS are there for when a user doesn\u2019t have a font; the browser will jump to the next one in the stack. Adding embedded fonts into the font stack means that because of FOUT (in gecko and Opera), the user can see a switch, and depending on their connection that switch could happen well into any reading that the user may be doing. \n\nThe practicalities of this are that a user could be reading and be towards the end of a line when the paragraph they are reading changes shape. The word they were digesting suddenly changes to three lines down. It\u2019s the online equivalent of someone turning the page for you when you least expect it. So, how can we think about our font stacks slightly differently so we can minimise the switch? \n\nTwo years ago, Richard Rutter wrote on this very site about increasing our font stacks. By increasing the font stacks (by using his handy matrix) we can begin to experiment with different typefaces. However, when we embed a typeface, we must look very carefully at the typefaces in the font stack and the relationship between them. Because, previously, the user would not see a switch from one typeface to another, they\u2019d just get either one or the other. Not both. With FOUT, the user sees two typefaces. \n\nBy carefully looking at the characteristics of the typefaces you choose, you can minimise the typographic \u2018distance\u2019 between the type down the stack. In doing so, you minimise the jarring effect of the switch. \n\nLet\u2019s take a look at an example of how to go about this. \n\nMicro Typography to build better font stacks \n\nLet\u2019s say I want to use a recent edition to Typekit \u2013 Meta Serif Book \u2013 as my embedded font. My font stack would start like this: \n\nfont-family: 'Meta Serif Bold'; \n\nWhere do you go from here? Well, first, familiarise yourself with Richard\u2019s Font Matrix so you get an idea of what fonts are available for different people. Then start by looking closely at the characters of the embedded font and then compare them to different fonts from the matrix. \n\nWhen I do this, I\u2019m looking to match type characteristics such as x-height, contrast (the thickness and thinness of strokes), the stress (the angle of contrast) and the shape of the serifs (if the typeface has any). \n\n\n\nUsing just these simple comparative metrics means you can get to a \u2018best fit\u2019 reasonably quickly. And remember, you\u2019re not after an ideal match. You\u2019re after a match that means the switch is less painful for the reader, but also a typeface that carries similar characteristics so your design doesn\u2019t change too much. \n\nBuilding upon my choice of embedded font, I can quickly build up a stack by comparing letters. \n\n\n\nThis then creates my \u2018best fit\u2019 stack. \n\n\n\nThis translates to the CSS as: \n\nfont-family: 'Meta Serif Bold', 'Lucida Bright', Cambria, Georgia, serif \n\nFollowing this process, and ending up with considered font stacks, means that we can design to the Flash of UnTypeset Content and ensure that our readers don\u2019t get a diminished experience.", "year": "2009", "author": "Mark Boulton", "author_slug": "markboulton", "published": "2009-12-16T00:00:00+00:00", "url": "https://24ways.org/2009/designing-for-the-switch/", "topic": "design"} {"rowid": 188, "title": "Don't Lose Your :focus", "contents": "For many web designers, accessibility conjures up images of blind users with screenreaders, and the difficulties in making sites accessible to this particular audience. Of course, accessibility covers a wide range of situations that go beyond the extreme example of screenreader users. And while it\u2019s true that making a complex site accessible can often be a daunting prospect, there are also many small things that don\u2019t take anything more than a bit of judicious planning, are very easy to test (without having to buy expensive assistive technology), and can make all the difference to certain user groups.\n\nIn this short article we\u2019ll focus on keyboard accessibility and how careless use of CSS can potentially make your sites completely unusable.\n\nKeyboard Access\n\nUsers who for whatever reason can\u2019t use a mouse will employ a keyboard (or keyboard-like custom interface) to navigate around web pages. By default, they will use TAB and SHIFT + TAB to move from one focusable element (links, form controls and area) of a page to the next.\n\nNote: in OS X, you\u2019ll first need to turn on full keyboard access under System Preferences > Keyboard and Mouse > Keyboard Shortcuts. Safari under Windows needs to have the option Press Tab to highlight each item on a webpage in Preferences > Advanced enabled. Opera is the odd one out, as it has a variety of keyboard navigation options \u2013 the most relevant here being spatial navigation via Shift+Down, Shift+Up, Shift+Left, and Shift+Right).\n\nBut I Don\u2019t Like Your Dotted Lines\u2026\n\nTo show users where they are within a page, browsers place an outline around the element that currently has focus. The \u201cproblem\u201d with these default outlines is that some browsers (Internet Explorer and Firefox) also display them when a user clicks on a focusable element with the mouse. Particularly on sites that make extensive use of image replacement on links with \u201coff left\u201d techniques this can create very unsightly outlines that stretch from the replaced element all the way to the left edge of the browser.\n\n Outline bleeding off to the left (image-replacement example from carsonified.com)\n\nThere is a trivial workaround to prevent outlines from \u201cspilling over\u201d by adding a simple overflow:hidden, which keeps the outline in check around the clickable portion of the image-replaced element itself.\n\n Outline tamed with overflow:hidden\n\nBut for many designers, even this is not enough. As a final solution, many actively suppress outlines altogether in their stylesheets. Controversially, even Eric Meyer\u2019s popular reset.css \u2013 an otherwise excellent set of styles that levels the playing field of varying browser defaults \u2013 suppresses outlines.\n\nhtml, body, div, span, applet, object, iframe ... {\n\t...\n\toutline: 0;\n\t...\n}\n/* remember to define focus styles! */\n:focus {\n\toutline: 0;\n}\n\nYes, in his explanation (and in the CSS itself) Eric does remind designers to define relevant styles for :focus\u2026 but judging by the number of sites that seem to ignore this (and often remove the related comment from the stylesheet altogether), the message doesn\u2019t seem to have sunk in.\n\nAnyway\u2026 hurrah! No more unsightly dotted lines on our lovely design. But what about keyboard users? Although technically they can still TAB from one element to the next, they now get no default cue as to where they are within the page (one notable exception here is Opera, where the outline is displayed regardless of stylesheets)\u2026 and if they\u2019re Safari users, they won\u2019t even get an indication of a link\u2019s target in the status bar, like they would if they hovered over it with the mouse.\n\nOnly Suppress outline For Mouse Users\n\nIs there a way to allow users navigating with the keyboard to retain the standard outline behaviour they\u2019ve come to expect from their browser, while also ensuring that it doesn\u2019t show display for mouse users?\n\n Testing some convoluted style combinations\n\nAfter playing with various approaches (see Better CSS outline suppression for more details), the most elegant solution also seemed to be the simplest: don\u2019t remove the outline on :focus, do it on :active instead \u2013 after all, :active is the dynamic pseudo-class that deals explicitly with the styles that should be applied when a focusable element is clicked or otherwise activated.\n\na:active { outline: none; }\n\nThe only minor issues with this method: if a user activates a link and then uses the browser\u2019s back button, the outline becomes visible. Oh, and old versions of Internet Explorer notoriously get confused by the exact meaning of :focus, :hover and :active, so this method fails in IE6 and below. Personally, I can live with both of these.\n\nNote: at the last minute before submitting this article, I discovered a fatal flaw in my test. It appears that outline still manages to appear in the time between activating a link and the link target loading (which in hindsight is logical \u2013 after activation, the link does indeed receive focus). As my test page only used in-page links, this issue never came up before. The slightly less elegant solution is to also suppress the outline on :hover.\n\na:hover, a:active { outline: none; }\n\nIn Conclusion\n\nOf course, many web designers may argue that they know what\u2019s best, even for their keyboard-using audience. Maybe they\u2019ve removed the default outline and are instead providing some carefully designed :focus styles. If they know for sure that these custom styles are indeed a reliable alternative for their users, more power to them\u2026 but, at the risk of sounding like Jakob \u201cblue underlined links\u201d Nielsen, I\u2019d still argue that sometimes the default browser behaviours are best left alone. Complemented, yes (and if you\u2019re already defining some fancy styles for :hover, by all means feel free to also make them display on :focus)\u2026 but not suppressed.", "year": "2009", "author": "Patrick Lauke", "author_slug": "patricklauke", "published": "2009-12-09T00:00:00+00:00", "url": "https://24ways.org/2009/dont-lose-your-focus/", "topic": "code"} {"rowid": 175, "title": "Front-End Code Reusability with CSS and JavaScript", "contents": "Most web standards-based developers are more than familiar with creating their sites with semantic HTML with lots and lots of CSS. With each new page in a design, the CSS tends to grow and grow and more elements and styles are added. But CSS can be used to better effect.\n\nThe idea of object-oriented CSS isn\u2019t new. Nicole Sullivan has written a presentation on the subject and outlines two main concepts: separate structure and visual design; and separate container and content. Jeff Croft talks about Applying OOP Concepts to CSS:\n\n\n\tI can make a class of .box that defines some basic layout structure, and another class of .rounded that provides rounded corners, and classes of .wide and .narrow that define some widths, and then easily create boxes of varying widths and styles by assigning multiple classes to an element, without having to duplicate code in my CSS.\n\n\nThis concept helps reduce CSS file size, allows for great flexibility, rapid building of similar content areas and means greater consistency throughout the entire design. You can also take this concept one step further and apply it to site behaviour with JavaScript.\n\nBuild a versatile slideshow\n\nI will show you how to build multiple slideshows using jQuery, allowing varying levels of functionality which you may find on one site design. The code will be flexible enough to allow you to add previous/next links, image pagination and the ability to change the animation type. More importantly, it will allow you to apply any combination of these features.\n\nImage galleries are simply a list of images, so the obvious choice of marking the content up is to use a
