{"rowid": 155, "title": "Minification: A Christmas Diet", "contents": "The festive season is generally more about gorging ourselves than staying thin but we\u2019re going to change all that with a quick introduction to minification.\n\nPerformance has been a hot topic this last year. We\u2019re building more complex sites and applications but at the same time trying to make then load faster and behave more responsively. What is a discerning web developer to do?\n\nMinification is the process of make something smaller, in the case of web site performance we\u2019re talking about reducing the size of files we send to the browser. The primary front-end components of any website are HTML, CSS, Javascript and a sprinkling of images. Let\u2019s find some tools to trim the fat and speed up our sites.\n\nFor those that want to play along at home you can download the various utilities for Mac or Windows. You\u2019ll want to be familiar with running apps on the command line too.\n\nHTMLTidy\n\nHTMLTidy optimises and strips white space from HTML documents. It also has a pretty good go at correcting any invalid markup while it\u2019s at it.\n\ntidy -m page.html\n\nCSSTidy\n\nCSSTidy takes your CSS file, optimises individual rules (for instance transforming padding-top: 10px; padding-bottom: 10px; to padding: 10px 0;) and strips unneeded white space.\n\ncsstidy style.css style-min.css\n\nJSMin\n\nJSMin takes your javascript and makes it more compact. With more and more websites using javascript to power (progressive) enhancements this can be a real bandwidth hog. Look out for pre-minified versions of libraries and frameworks too.\n\njsmin <script.js >script-min.js\n\nRemember to run JSLint before you run JSMin to catch some common problems.\n\nOptiPNG\n\nImages can be a real bandwidth hog and making all of them smaller with OptiPNG should speed up your site.\n\noptipng image.png\n\nAll of these tools have an often bewildering array of options and generally good documentation included as part of the package. A little experimentation will get you even more bang for your buck.\n\nFor larger projects you likely won\u2019t want to be manually minifying all your files. The best approach here is to integrate these tools into your build process and have your live website come out the other side smaller than it went in.\n\nYou can also do things on the server to speed things up; GZIP compression for instance or compilation of resources to reduce the number of HTTP requests. If you\u2019re interested in performance a good starting point is the Exceptional Performance section on the Yahoo Developer Network and remember to install the YSlow Firebug extension while you\u2019re at it.", "year": "2007", "author": "Gareth Rushgrove", "author_slug": "garethrushgrove", "published": "2007-12-06T00:00:00+00:00", "url": "https://24ways.org/2007/minification-a-christmas-diet/", "topic": "process"}
{"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": 19, "title": "In Their Own Write: Web Books and their Authors", "contents": "The currency of written communication \u2014 words on the page, words on the screen \u2014 comprises many denominations. To further our ends in web design and development, we freely spend and receive several: tweets aphoristic and trenchant, banal and perfunctory; blog posts and articles that call us to action or reflection; anecdotes, asides, comments, essays, guides, how-tos, manuals, musings, notes, opinions, stories, thoughts, tips pro and not-so-pro. So many, many words.\n\nOur industry (so much more than this, but what on earth are we, collectively?), our community thrives on writing and sharing knowledge and experience. 24 ways is a case in point. Everyone can learn and contribute through reading and writing \u2014 it\u2019s what we\u2019ve always done.\n\nTo web authors and readers seeking greater returns, though, broader culture has vouchsafed an enduring and singular artefact: the book.\n\nLast month I asked a small sample of web book authors if they would be prepared to answer a few questions; most of them kindly agreed. In spirit, the survey was informal: I had neither hypothesis nor unground axe. I work closely with writers \u2014 and yes, I\u2019ve edited or copy-edited books by several of the authors I surveyed \u2014 and wanted to share their thoughts about what it was like to write a book (\u201c\u2026it was challenging to find a coherent narrative\u201d), why they did it (\u201cWho wouldn\u2019t want to?\u201d) and what they learned from the experience (\u201cThat I could!\u201d).\n\nReasons for writing a book\n\nIn web development the connection between authors and readers is unusually close and immediate. Working in our medium precipitates a unity that\u2019s rare elsewhere. Yet writing and publishing a book, even during the current books revolution, is something only a few of us attempt and it remains daunting and a little remote. What spurs an author to try it? For some, it\u2019s a deeply held resistance to prevailing trends:\n\nI felt that designers and developers needed to be shaken out of what seemed to me had been years of stagnation.\n\u2014Andrew Clarke\n\n\nOr even a desire to protect us from ourselves:\n\nI felt that without a book that clearly defined progressive enhancement in a very approachable and succinct fashion, the web was at risk. I was seeing Tim Berners-Lee\u2019s vision of universal availability slip away\u2026\n\u2014Aaron Gustafson\n\n\nSometimes, there\u2019s a knowledge gap to be filled by an author with the requisite excitement and need to communicate. Jon Hicks took his \u201cpet subject\u201d and was \u201centhused enough to want to spend all that time writing\u201d, particularly because:\n\n\n\t\u2026there was a gap in the market for it. No one had done it before, and it\u2019s still on its own out there, with no competition. It felt like I was able to contribute something.\n\n\nCennydd Bowles felt a professional itch at a particular point in his career, understanding that\n\n\n\t[a]s a designer becomes more senior, they start looking for ways to scale the effects of their work. For some, that leads into management. For others, into writing.\n\n\nOften, though, it\u2019s also simply a personal challenge and ambition to explore a subject at length and create something substantial. Anna Debenham describes a motivation shared by several authors:\n\nTo be able to point to something more tangible than an article and be able to say \u201cI did that.\u201d\n\n\nThat sense of a book\u2019s significance, its heft and gravity even, stems partly from the cultural esteem which honours books and their authors. Books have a long history as sources of wisdom, truth and power. Even with more books being published each year than ever before, writing one is still commonly considered a laudable achievement, including in our field.\n\nChallenges of writing a book\n\nReceived wisdom has it that writing online should be brief and chunky and approachable: get to the point; divide it all up; subheadings and lists are our friends; write like you\u2019re talking; no one has time to read. Much of such advice is true. Followed well, it lends our writing punch and pith, vigour and vim. The web is nimble, the web keeps up, and it suits what we write about developing for it. It\u2019s perfect for delivering our observations, queries and investigations into all the various aspects of the work, professional and personal.\n\nYet even for digital natives like web authors, books printed and electronic retain an attractive glister. \n\nIdeas can be developed more fully, their consequences explored to greater depth and extended with more varied examples, and the whole conveyed with more eloquence, more style. Why shouldn\u2019t authors delay their conclusions if the intervening text is apposite, rich with value and helps to flesh out the skeleton of an argument? Conclusions might or might not be reached, of course, but a writer is at greater liberty in a book to digress in tangential and interesting ways.\n\nWriting a book involves committing time, energy, thought and money. As Brian Suda found, it can be tough \u201cgetting the ideas out of my head into a cohesive blob of text.\u201d Some authors end up talking to themselves\u2026\n\nIt helps me to keep a real person in mind, someone who I\u2019m talking to as I write. Sometimes I have the same conversations over and over in my head.\n\u2014Andrew Clarke\n\n\n\u2026while others are thinking ahead, concerned with how their book will be received:\n\nWould anyone want to read it? Would they care? Would it be respected by my peers?\n\u2014Joe Leech\n\n\nChallenges that arose time and again included \u201cstarting\u201d and \u201cgetting words on the page\u201d as well as \u201cknowing when to stop\u201d or \u201cletting go\u201d. Personal organization problems and those caused by publishers were also widely mentioned. Time loomed large. Making time, finding time. Giving up \u201csleep and some sanity\u201d and realizing \u201cit will take you far, far, far longer than you naively assumed\u201d. Importantly, writing time is time away from gainful employment: Aaron Gustafson found the hardest thing about writing a book to be \u201cthe loss of income while I was writing.\u201d\n\nPerils and pleasures of editing\n\nEditing, be it structural, technical or copy editing, is founded on reciprocity. Without openness and a shared belief that the book is worthwhile, work can founder in acrimony and mistrust. Editors are a book\u2019s first and most critical (in every sense) readers. Effective and perceptive editing makes a book as good as it can be, finding the book within the draft like sculpture reveals the statue in the stone.\n\nA good editor calls you out on poor assumptions and challenges you to really clarify your thinking. Whilst it can be difficult during the process to have your thinking challenged, it\u2019s always been worth it \u2014 for me personally \u2014 in the long run. A good editor also reins you in when you\u2019ve perhaps wandered off track or taken a little too long to make a point.\n\u2014Christopher Murphy\n\n\nAndy Croll found editing \u201call positive\u201d and Aaron Gustafson loves \u201cworking with a strong editor [\u2026] I want someone to tell it to me straight.\u201d But it can be a rollercoaster, \u201cboth terrifying and the real moment of elation\u201d. Mixed emotions during the editing process are common:\n\nIt was very uncomfortable! I knew it was making the work stronger, but it was awkward having my inconsistencies and waffle picked apart.\n\u2014Jon Hicks\n\n\nIt can be distressing to have written work looked over by a professional, particularly for first-time book authors whose expertise lies elsewhere:\n\nI was a little nervous because I don\u2019t consider myself a skilled writer \u2014 I never dreamed of becoming an author. I\u2019m a designer, after all.\n\u2014Geri Coady\n\n\nCommunication is key, particularly when it comes to checking or changing the author\u2019s words.\n\nI like a good banter between me and the tech editor \u2014 if we can have a proper argument in Word comments, that\u2019s great.\n\u2014Rachel Andrew\n\n\nBut if handled poorly, small battles can break out. Rachel Andrew again:\n\n\n\tHowever, having had plenty of times where the technical editor has done nothing more than give a cursory glance, I started to leave little issues in for them to spot. If they picked them up I knew they were actually testing the code and I could be sure the work was being properly tech edited. If they didn\u2019t spot them, I\u2019d find someone myself to read through and check it!\n\n\nA major concern for writers is that their voices will be altered, filtered, mangled or otherwise obscured by the editing process. Good copy editing must remain unnoticed while enhancing the author\u2019s voice in print. Donna Spencer appreciated the way her editor \u201ctidied up my work and made it a million times better, but left it sounding exactly like me.\u201d Similarly, Andrew Travers \u201cwas incredibly impressed at how well my editor tightened up my own writing without it feeling like another\u2019s voice\u201d and Val Head sums up the consensus that:\n\n\n\tthe editor was able to help me express what I was trying to say in a better way [\u2026] I want to have editors for everything now.\n\n\nAt the keyboard, keep your friends close, but your editors closer.\n\nPublishing and publishers\n\nConditions ought to militate against the allure of writing a book about web design and development. More books are published each year than ever before, so readerships elude new authors and readers can struggle to find authors to trust in their fields of interest. New spaces for more expansive online writing about working on and with the web are opening up (sites like Contents Magazine and STET), and seminal online web development texts are emerging. Publishing online is simple, far-reaching and immediate.\n\nMuch more so than articles and blog posts, books take time to research, write and read; add the complexity of commissioning, editing, designing, proofreading, printing, marketing and distribution processes, and it can take many months, even years to publish. The ceaseless headlong momentum of the web can leave articles more than a few weeks old whimpering in its wake, but updating them at least is straightforward; printed books about web development can depreciate as rapidly as the technology and techniques they describe, while retaining the \u201cterrifying permanence that print bestows: your opinions will follow you forever\u201d.\n\nSo much moves on, and becomes out of date. Companies featured get bought by larger companies and die, techniques improve and solutions featured become terribly out of date. Unlike a website, which could be updated continuously, a book represents the thinking \u2018at that time\u2019.\n\u2014Jon Hicks\n\n\nPublishers work hard to mitigate these issues, promoting new books and new authors, bringing authors and readers together under a trusted banner. When a publisher packages up and releases a writer\u2019s words, it confers a seal of approval and \u201cbadge of quality\u201d, very important to new authors.\n\nPublishers have other benefits to offer, from expert knowledge:\n\nMy publisher was extraordinarily supportive (and patient). Her expertise in my chosen subject was both a pressure (I didn\u2019t want to let her down) and a reassurance (if she liked it, I knew it was going to be fine).\n\u2014Andrew Travers\n\n\n\u2026to systems and support mechanisms set up specifically to encourage writers and publish books:\n\nWorking as a team means you\u2019re bringing in everyone\u2019s expertise.\n\u2014Chui Chui Tan\n\n\nAs a writer, the best part about writing for a publisher was the writing infrastructure offered.\n\u2014Christopher Murphy\n\n\nThere can be drawbacks, however, and the occasional horror story:\n\nWe were just one small package on a huge conveyor belt. The publisher\u2019s process ruled all.\n\u2014Cennydd Bowles\n\n\nIt\u2019s only looking back I realise how poorly some publishers treat writers \u2014 especially when the work is so poorly remunerated.My worst experience was when a publisher decided, after I had completed the book, that they wanted to push a different take on the subject than the brief I had been given. Instead of talking to me, they rewrote chunks of my words, turning my advice into something that I would never have encouraged. Ultimately, I refused to let the book go out under my name alone, and I also didn\u2019t really promote the book as I would have had to point out the things I did not agree with that had been inserted!\n\u2014Rachel Andrew\n\n\nSelf-publishing is now a realistic option for web authors, and can offers \u201ccomplete control over the end product\u201d as well as the possibility of earning more than a \u201cpathetic author revenue percentage\u201d. There can be substantial barriers, of course, as self-publishing authors must face for themselves the risks and challenges conventional publishers usually bear. Ideally, creating a book is a collaboration between author and publisher. Geri Coady found that \u201cworking with my publisher felt more like working with a partner or co-worker, rather than working for a boss.\u201d\n\nWise words\n\nSo, after meeting the personal costs of writing and publishing a web book \u2014 fear, uncertainty, doubt, typing (so much typing) \u2014 and then smelling the roses of success, what\u2019s left for an author to say? Some words, perhaps, to people thinking of writing a book.\n\nDonna Spencer identifies a stumbling block common to many writers with an insight into the writing process:\n\n\n\tHaving talked to a lot of potential authors, I think most have the problem that they haven\u2019t actually figured out the \u2018answer\u2019 to their premise yet. They feel like they are stuck in the writing, but they are actually stuck in the thinking.\n\n\nFor some no-nonsense, straightforward advice to cut through any anxiety or inadequacy, Rachel Andrew encourages authors to \u201ctreat it like any other work. There is no mystery to writing, you just have to write. Schedule the time, sit down, write words.\u201d Tim Brown notes the importance of the editing process to refine a book and help authors reach their readers:\n\n\n\tHire good editors. Editors are amazing thinkers who can vastly improve the quality and clarity of a piece of writing.\n\n\nWe are too much beholden to the practical demands and challenges of technology, so Aaron Gustafson suggests a writer should \u201cfavor philosophies over techniques and your book will have a longer shelf life.\u201d\n\nMost intimations of renown and recognition are nipped in the bud by Joe Leech\u2019s warning: \u201cDon\u2019t expect fame and fortune.\u201d Although Cennydd Bowles\u2019 bitter experience can be discouraging:\n\n\n\tThe sacrifices required are immense. You probably won\u2019t make it.\n\n\n\u2026he would do things differently for a future book:\n\n\n\tI would approach the book with [\u2026] far more concern about conveying the damn joy of what I do for a living.\n\n\nThe pleasure of writing, not just having written is captured by James Chudley when he recalls:\n\n\n\tHow much I enjoy writing and also how much I enjoy the discipline or having a side project like this. It\u2019s a really good supplement to working life.\n\n\nAnd Jon Hicks has words that any author will find comforting:\n\n\n\tIt will be fine. Everything will be fine. Just get on with it!\n\n\n\n\nAs the web expands effortlessly and ceaselessly to make room for all our words, yet it can also discourage the accumulation of any particular theme in one space, dividing rich seams and scattering knowledge across the web\u2019s surface and into its deepest reaches. How many words become weightless and insubstantial, signals lost in the constant white noise of indistinguishable voices, unloved, unlinked? The web forgets constantly, despite the (somewhat empty) promise of digital preservation: articles and data are sacrificed to expediency, profit and apathy; online attention, acknowledgement and interest wax and wane in days, hours even.\n\nBooks can encourage deeper engagement in readers, and foster faith in an author, particularly if released under the imprint of a recognized publisher within the field. And books are changing. Although still not widely adopted, EPUB3 is the new standard in ebooks, bringing with it new possibilities for interaction and connection: readers with the text; readers with readers; and readers with authors. EPUB3 is built on HTML, CSS and JavaScript \u2014 sound familiar? In the past, we took what we could from the printed page to make the web; now books are rubbing up against what we\u2019ve made.\n\nSo: a book.\n\nEver thought you could write one? Should write one? Would?\n\n\n\nI\u2019d like to thank all the authors who wrote their books and answered my questions.\n\n\n\tRachel Andrew \u00b7 CSS3 Layout Modules, The CSS3 Anthology and more\n\tCennydd Bowles \u00b7 Undercover User Experience Design, with James Box\n\tTim Brown \u00b7 Combining Typefaces\n\tJames Chudley \u00b7 Usability of Web Photos\n\tAndrew Clarke \u00b7 Hardboiled Web Design\n\tGeri Coady \u00b7 Colour Accessibility\n\tAndy Croll \u00b7 HTML Email\n\tAnna Debenham \u00b7 Front-end Style Guides\n\tAaron Gustafson \u00b7 Adaptive Web Design\n\tVal Head \u00b7 CSS Animations\n\tJon Hicks \u00b7 The Icon Handbook\n\tJoe Leech \u00b7 Psychology for Designers\n\tChristopher Murphy \u00b7 The Craft of Words, with Niklas Persson\n\tDonna Spencer \u00b7 Information Architecture, Card Sorting and How to Write Great Copy for the Web\n\tBrian Suda \u00b7 Designing with Data\n\tChui Chui Tan \u00b7 International User Research\n\tAndrew Travers \u00b7 Interviewing for Research", "year": "2013", "author": "Owen Gregory", "author_slug": "owengregory", "published": "2013-12-15T00:00:00+00:00", "url": "https://24ways.org/2013/web-books/", "topic": "content"}
{"rowid": 126, "title": "Intricate Fluid Layouts in Three Easy Steps", "contents": "The Year of the Script may have drawn attention away from CSS but building fluid, multi-column, cross-browser CSS layouts can still be as unpleasant as a lump of coal. Read on for a worry-free approach in three quick steps.\n\nThe layout system I developed, YUI Grids CSS, has three components. They can be used together as we\u2019ll see, or independently.\n\nThe Three Easy Steps\n\n\n\tChoose fluid or fixed layout, and choose the width (in percents or pixels) of the page.\n\tChoose the size, orientation, and source-order of the main and secondary blocks of content.\n\tChoose the number of columns and how they distribute (for example 50%-50% or 25%-75%), using stackable and nestable grid structures.\n\n\nThe Setup\n\nThere are two prerequisites: We need to normalize the size of an em and opt into the browser rendering engine\u2019s Strict Mode.\n\nEms are a superior unit of measure for our case because they represent the current font size and grow as the user increases their font size setting. This flexibility\u2014the container growing with the user\u2019s wishes\u2014means larger text doesn\u2019t get crammed into an unresponsive container. We\u2019ll use YUI Fonts CSS to set the base size because it provides consistent-yet-adaptive font-sizes while preserving user control.\n\nThe second prerequisite is to opt into Strict Mode (more info on rendering modes) by declaring a Doctype complete with URI. You can choose XHTML or HTML, and Transitional or Strict. I prefer HTML 4.01 Strict, which looks like this:\n\n<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.01//EN\" \"http://www.w3.org/TR/html4/strict.dtd\">\n\nIncluding the CSS\n\nA single small CSS file powers a nearly-infinite number of layouts thanks to a recursive system and the interplay between the three distinct components. You could prune to a particular layout\u2019s specific needs, but why bother when the complete file weighs scarcely 1.8kb uncompressed? Compressed, YUI Fonts and YUI Grids combine for a miniscule 0.9kb over the wire.\n\nYou could save an HTTP request by concatenating the two CSS files, or by adding their contents to your own CSS, but I\u2019ll keep them separate for now:\n\n<link href=\"fonts.css\" rel=\"stylesheet\" type=\"text/css\">\n<link href=\"grids.css\" rel=\"stylesheet\" type=\"text/css\">\n\nExample: The Setup\n\nNow we\u2019re ready to build some layouts.\n\nStep 1: Choose Fluid or Fixed Layout\n\nChoose between preset widths of 750px, 950px, and 100% by giving a document-wrapping div an ID of doc, doc2, or doc3. These options cover most use cases, but it\u2019s easy to define a custom fixed width.\n\nThe fluid 100% grid (doc3) is what I\u2019ve been using almost exclusively since it was introduced in the last YUI released.\n\n<body>\n\t<div id=\"doc3\"></div>\n</body>\n\nAll pages are centered within the viewport, and grow with font size. The 100% width page (doc3) preserves 10px of breathing room via left and right margins. If you prefer your content flush to the viewport, just add doc3 {margin:auto} to your CSS.\n\nRegardless of what you choose in the other two steps, you can always toggle between these widths and behaviors by simply swapping the ID value. It\u2019s really that simple.\n\nExample: 100% fluid layout\n\nStep 2: Choose a Template Preset\n\nThis is perhaps the most frequently omitted step (they\u2019re all optional), but I use it nearly every time. In a source-order-independent way (good for accessibility and SEO), \u201cTemplate Presets\u201d provide commonly used template widths compatible with ad-unit dimension standards defined by the Interactive Advertising Bureau, an industry association.\n\nChoose between the six Template Presets (.yui-t1 through .yui-t6) by setting the class value on the document-wrapping div established in Step 1. Most frequently I use yui-t3, which puts the narrow secondary block on the left and makes it 300px wide. \n\n<body>\n\t<div id=\"doc3\" class=\"yui-t3\"></div>\n</body>\n\nThe Template Presets control two \u201cblocks\u201d of content, which are defined by two divs, each with yui-b (\u201cb\u201d for \u201cblock\u201d) class values. Template Presets describe the width and orientation of the secondary block; the main block will take up the rest of the space.\n\n<body>\n\t<div id=\"doc3\" class=\"yui-t3\">\n\t  <div class=\"yui-b\"></div>\n\t  <div class=\"yui-b\"></div>\n\t</div>\n</body>\n\nUse a wrapping div with an ID of yui-main to structurally indicate which block is the main block. This wrapper\u2014not the source order\u2014identifies the main block.\n\n<body>\n\t<div id=\"doc3\" class=\"yui-t3\">\n\t  <div id=\"yui-main\">\n\t    <div class=\"yui-b\"></div>\n\t  </div>\n\t  <div class=\"yui-b\"></div>\n\t</div>\n</body>\n\nExample: Main and secondary blocks sized and oriented with .yui-t3 Template Preset\n\nAgain, regardless of what values you choose in the other steps, you can always toggle between these Template Presets by toggling the class value of your document-wrapping div. It\u2019s really that simple.\n\nStep 3: Nest and Stack Grid Structures.\n\nThe bulk of the power of the system is in this third step. The key is that columns are built by parents telling children how to behave. By default, two children each consume half of their parent\u2019s area. Put two units inside a grid structure, and they will sit side-by-side, and they will each take up half the space. Nest this structure and two columns become four. Stack them for rows of columns.\n\nAn Even Number of Columns\n\nThe default behavior creates two evenly-distributed columns. It\u2019s easy. Define one parent grid with .yui-g (\u201cg\u201d for grid) and two child units with .yui-u (\u201cu\u201d for unit). The code looks like this:\n\n<div class=\"yui-g\">\n\t<div class=\"yui-u first\"></div>\n\t<div class=\"yui-u\"></div>\n</div>\n\nBe sure to indicate the \u201cfirst\u201c unit because the :first-child pseudo-class selector isn\u2019t supported across all A-grade browsers. It\u2019s unfortunate we need to add this, but luckily it\u2019s not out of place in the markup layer since it is structural information.\n\nExample: Two evenly-distributed columns in the main content block\n\nAn Odd Number of Columns\n\nThe default system does not work for an odd number of columns without using the included \u201cSpecial Grids\u201d classes. To create three evenly distributed columns, use the \u201cyui-gb\u201c Special Grid:\n\n<div class=\"yui-gb\">\n\t<div class=\"yui-u first\"></div>\n\t<div class=\"yui-u\"></div>\n\t<div class=\"yui-u\"></div>\n</div>\n\nExample: Three evenly distributed columns in the main content block\n\nUneven Column Distribution\n\nSpecial Grids are also used for unevenly distributed column widths. For example, .yui-ge tells the first unit (column) to take up 75% of the parent\u2019s space and the other unit to take just 25%.\n\n<div class=\"yui-ge\">\n\t<div class=\"yui-u first\"></div>\n\t<div class=\"yui-u\"></div>\n</div>\n\nExample: Two columns in the main content block split 75%-25%\n\nPutting It All Together\n\nStart with a full-width fluid page (div#doc3). Make the secondary block 180px wide on the right (div.yui-t4). Create three rows of columns: Three evenly distributed columns in the first row (div.yui-gb), two uneven columns (66%-33%) in the second row (div.yui-gc), and two evenly distributed columns in the thrid row.\n\n<body>\n\t<!-- choose fluid page and Template Preset -->\n\t<div id=\"doc3\" class=\"yui-t4\">\n\t\t<!-- main content block -->\n\t\t<div id=\"yui-main\">\n\t\t\t<div class=\"yui-b\">\n\t\t\t\t<!-- stacked grid structure, Special Grid \"b\" -->\n\t\t\t\t<div class=\"yui-gb\">\n\t\t\t\t\t<div class=\"yui-u first\"></div>\n\t\t\t\t\t<div class=\"yui-u\"></div>\n\t\t\t\t\t<div class=\"yui-u\"></div>\n\t\t\t\t</div>\n\t\t\t\t<!-- stacked grid structure, Special Grid \"c\" -->\n\t\t\t\t<div class=\"yui-gc\">\n\t\t\t\t\t<div class=\"yui-u first\"></div>\n\t\t\t\t\t<div class=\"yui-u\"></div>\n\t\t\t\t</div>\n\t\t\t\t<!-- stacked grid structure -->\n\t\t\t\t<div class=\"yui-g\">\n\t\t\t\t\t<div class=\"yui-u first\"></div>\n\t\t\t\t\t<div class=\"yui-u\"></div>\n\t\t\t\t</div>\n\t\t\t</div>\n\t\t</div>\n\t\t<!-- secondary content block -->\n\t\t<div class=\"yui-b\"></div>\n\t</div>\n</body>\n\nExample: A complex layout.\n\nWasn\u2019t that easy? Now that you know the three \u201clevers\u201d of YUI Grids CSS, you\u2019ll be creating headache-free fluid layouts faster than you can say \u201cPeace on Earth\u201d.", "year": "2006", "author": "Nate Koechley", "author_slug": "natekoechley", "published": "2006-12-20T00:00:00+00:00", "url": "https://24ways.org/2006/intricate-fluid-layouts/", "topic": "code"}
{"rowid": 96, "title": "Unwrapping the Wii U Browser", "contents": "The Wii U was released on 18 November 2012 in the US, and 30 November in the UK. It\u2019s the first eighth generation home console, the first mainstream second-screen device, and it has some really impressive browser specs.\n\nConsoles are not just for games now: they\u2019re marketed as complete entertainment solutions. Internet connectivity and browser functionality have gone from a nice-to-have feature in game consoles to a selling point. In Nintendo\u2019s case, they see it as a challenge to design an experience that\u2019s better than browsing on a desktop.\n\n\n\tLet\u2019s make a browser that users can use on a daily basis, something that can really handle everything we\u2019ve come to expect from a browser and do it more naturally.\nSasaki \u2013 Iwata Asks on Nintendo.com\n\n\nWith 11% of people using console browsers to visit websites, it\u2019s important to consider these devices right from the start of projects. Browsing the web on a TV or handheld console is a very different experience to browsing on a desktop or a mobile phone, and has many usability implications.\n\nConsole browser testing\n\nWhen I\u2019m testing a console browser, one of the first things I do is run Niels Leenheer\u2019s HTML5 test and Lea Verou\u2019s CSS3 test. I use these benchmarks as a rough comparison of the standards each browser supports.\n\nIn October, IE9 came out for the Xbox 360, scoring 120/500 in the HTML5 test and 32% in the CSS3 test. The PS Vita also had an update to its browser in recent weeks, jumping from 58/500 to 243/500 in the HTML5 test, and 32% to 55% in the CSS3 test. Manufacturers have been stepping up their game, trying to make their browsing experiences better.\n\nTo give you an idea of how the Wii U currently compares to other devices, here are the test results of the other TV consoles I\u2019ve tested. I\u2019ve written more in-depth notes on TV and portable console browsers separately.\n\n\nYear of releaseHTML5 scoreCSS3 scoreNotes\nWii U2012258/50048%Runs a Netfront browser (WebKit).\nWii200689/500Wouldn\u2019t runRuns an Opera browser.\nPS3200668/50038%Runs a Netfront browser (WebKit).\nXbox 3602005120/50032%A browser for the Xbox (IE9) was only recently released in October 2012. The Kinect provides voice and gesture support. There\u2019s also SmartGlass, a second-screen app for platforms including Android and iOS.\n\n\nThe Wii U browser is Nintendo\u2019s fifth attempt at a console browser. Based on these tests, it\u2019s already looking promising.\n\nWhy console browsers used to suck\n\nIt takes a lot of system memory to run a good browser, and the problem of older consoles is that they don\u2019t have much memory available. The original Nintendo DS needs a memory expansion pack just to run the browser, because the 4MB it has on board isn\u2019t enough. I noticed that even on newer devices, some sites fail to load because the system runs out of memory.\n\nThe Wii came out six years ago with an Opera browser. Still being used today and with such low resources available, the latest browser features can\u2019t reasonably be supported. There\u2019s also pressure to add features such as tabs, and enable gamers to use the browser while a game is paused. Nintendo\u2019s browser team have the advantage of higher specs to play with on their new console (1GB of memory dedicated to games, 1GB for the system), which makes it easier to support the latest standards. But it\u2019s still a challenge to fit everything in.\n\n\n\t\u2026even though we have more memory, the amount of memory we can use for the browser is limited compared to a PC, so we\u2019ve worked in ways that efficiently allocates the available memory per tab. To work on this, the experience working on the browser for the Nintendo 3DS system under a limited memory constraint helped us greatly.\nSasaki \u2013 Iwata Asks on Nintendo.com\n\n\nIn the box\n\nThe Wii U consists of a console unit which plugs into a TV (the first to support HD), and a wireless controller known as a gamepad. The gamepad is a lot bigger than typical TV console controllers, and it has a touchscreen on the front. The touchscreen is resistive, responding to pressure rather than electrical current. It\u2019s intended to be used with a stylus (provided) but fingers can be used.\n\nIt might look a bit like one, but the gamepad isn\u2019t a portable console designed to be taken out like the PS Vita. The gamepad can be used as a standalone screen with the TV switched off, as long as it\u2019s within range of the console unit \u2013 it basically piggybacks off it.\n\n\n\nIt\u2019s surprisingly lightweight for its size. It has a wealth of detectors including 9-axis control. Sensors wake the device from sleep when it\u2019s picked up. There\u2019s also a camera on the front, and a headphone port and speakers, with audio coming through both the TV and the gamepad giving a surround sound feel.\n\nUp to six tabs can be opened at once, and the browser can be used while games are paused. There\u2019s a really nice little feature here \u2013 the current game\u2019s name is saved as a search option, so it\u2019s really quick to look up contextual content such as walk-throughs.\n\nControls\n\nOnly one gamepad can be used to control the browser, but if there are Wiimotes connected, they can be used as pointers. This doesn\u2019t let the user do anything except point (they each get a little hand icon with a number on it displayed on the screen), but it\u2019s interesting that multiple people can be interacting with a site at once.\n\n\n\nSee a bigger version\n\nThe gamepad can also be used as a simple TV remote control, with basic functions such as bringing up the programme guide, adjusting volume and changing channel. I found the simplified interface much more usable than a full-featured remote control.\n\n\n\nI\u2019m used to scrolling being sluggish on consoles, but the Wii U feels almost as snappy as a desktop browser. Sites load considerably faster compared with others I\u2019ve tested.\n\nTilt-scroll\n\nHolding down ZL and ZR while tilting the screen activates an Instapaper-style tilt to scroll for going up and down the page quickly, useful for navigating very long pages.\n\nSecond screen\n\nThe TV mirrors most of what\u2019s on the gamepad, although the TV screen just displays the contents of the browser window, while the gamepad displays the site along with the browser toolbar.\n\nWhen the user with the gamepad is typing, the keyboard is hidden from the TV screen \u2013 there\u2019s just a bit of text at the top indicating what\u2019s happening on the gamepad.\n\nPressing X draws an on-screen curtain over the TV, hiding the content that\u2019s on the gamepad from the TV. Pressing X again opens the curtains, revealing what\u2019s on the gamepad. Holding the button down plays a drumroll before it\u2019s released and the curtains are opened. I can imagine this being used in meetings as a fun presentation tool.\n\n\n\n\n\tIn a sense, browsing is a personal activity, but you get the idea that people will be coming and going through the room. When I first saw the curtain function, it made a huge impression on me. I walked around with it all over the company saying, \u201cThey\u2019ve really come up with something amazing!\u201d\nIwata \u2013 Iwata Asks on Nintendo.com\n\n\nText\n\nWriting text\n\nUnlike the capacitive screens on smartphones, the Wii U\u2019s resistive screen needs to be pressed harder than you\u2019re probably used to for registering a touch event. The gamepad screen is big, which makes it much easier to type on this device than other handheld consoles, even without the stylus. It\u2019s still more fiddly than a full-sized keyboard though. When you\u2019re designing forms, consider the extra difficulty console users experience.\n\n\n\nAlthough TV screens are physically big, they are typically viewed from further away than desktop screens. This makes readability an issue, so Nintendo have provided not one, but four ways to zoom in and out:\n\n\n\tDouble-tapping on the screen.\n\tTapping the on-screen zoom icons in the browser toolbar.\n\tPressing the + and - buttons on the device.\n\tMoving the right analogue stick up and down.\n\n\nAs well as making it easy to zoom in and out, Nintendo have done a few other things to improve the reading experience on the TV.\n\nSystem font\n\nOne thing you\u2019ll notice pretty quickly is that the browser lacks all the fonts we\u2019re used to falling back to. Serif fonts are replaced with the system\u2019s sans-serif font. I couldn\u2019t get Typekit\u2019s font loading method to work but Fontdeck, which works slightly differently, does display custom fonts.\n\n The system font has been optimised for reading at a distance and is easy to distinguish because the lowercase e has a quirky little tilt.\n\nDon\u2019t lose :focus\n\nUsing the D-pad to navigate is similar to using a keyboard. Individual links are focused on, with a blue outline drawn around them.\n\nThe recently redesigned An Event Apart site is an example that improves the experience for keyboard and D-pad users. They\u2019ve added a yellow background colour to links on focus. It feels nicer than the default blue outline on its own.\n\n\n\nMedia\n\nThis year, television overtook PCs as the primary way to watch online video content. TV is the natural environment for video, and 42% of online TVs in the US are connected to the internet via a console. Unfortunately, the <video> tag isn\u2019t supported in most console browsers, and those that have Flash installed often have such an old version that the video won\u2019t play.\n\nI suspect this has been a big driver in getting console browsers to support web standards. The Wii U is designed with video content in mind. It doesn\u2019t support Flash but it does support the HTML5 <video> tag.\n\nSome video formats can\u2019t be played, but those that are supported bring up an optimised interface with a custom scrub bar. This is where the device switches from mirroring the TV to being a second screen. The full-screen video is displayed on the TV, and the interface on the gamepad.\n\nThe really clever bit is that while a video is playing, the gamepad user can keep the video playing on the TV screen while searching for another video or browsing the web. This is the same for images too.\n\nOn the left, the video is being shown full-screen on the TV and gamepad. Only the gamepad gets the scrub bar. Clicking the slide up/down button (circled) lets the gamepad user browse the web while the video on the TV continues to play full-screen, as shown in the image on the right.\n\nThere\u2019s support for SVG images, and they look great on a high-definition TV screen. However, there\u2019s currently no way to save or download files.\n\nPreparing for console users\n\nI wasn\u2019t expecting to be quite as impressed as I am by this browser. It\u2019s encouraging to see console makers investing time into improving the experience as well as the standards support. In the same way there was an explosion in mobile browser use as the experience got better, I\u2019m sure we\u2019ll see the same with console browsers as the experience improves.\n\nThe value of detection\n\nConsoles offer a range of inputs including gesture, voice and controller buttons. That means we have to think about more diverse methods of input than just touch and click.\n\nThis is where I could tell you to add some detection methods such as user agent string sniffing to target a different experience for console users. But the majority of the time, that really isn\u2019t necessary. TV console browsers are getting a lot better at compensating for the living room environment, and they\u2019re designed to work with websites that haven\u2019t been optimised for this context.\n\nRather than tighten our grip on optimising experiences for every device out there, we\u2019ve got to be pragmatic. There are so many new devices coming out every week, our designs need to be future-proof rather than fixed to a particular device in time.\n\nEven fuzzy device detection isn\u2019t reliable \u2013 the PS Vita declares itself to be mobile, a mobile device and a Kindle Fire tablet, while the two DS devices state they\u2019re neither mobile nor mobile phones nor tablets, but computers. They\u2019re weird outliers, but they\u2019re still important devices to consider.\n\nThinking broadly about how our designs will be interacted with and viewed on a TV screen can help improve that experience for everyone. This is about accessibility. Considering how someone uses a site with a D-pad, we can improve the experience for keyboard users. When we think about colour contrast and text legibility on TV screens, we can apply that for anyone who reads content on the web. So why just offer this to the TV users?\n\nPlaying with the browser\n\n\n\t\u2026we want to prove to them through this Wii U Internet Browser that browsing itself can be an entertainment.\nIwata \u2013 Iwata Asks on Nintendo.com\n\n\nAlthough I\u2019m cautious about designing experiences for specific devices, it\u2019s fun to experiment with the technology available. Nintendo have promised web developers access to the Wii U\u2019s buttons and sensors. There\u2019s already some JavaScript documentation, and a demo for you to try.\n\nIf you\u2019re interested in making your own games, thanks to web standards, a lot of HTML5 games work already on the device. Matt Hackett wrote up his experience of testing the game he built, and he talks about some of features the browser lacks. There\u2019s certainly an incentive there for console manufacturers to improve their HTML5 support so more games can be played in their browser.\n\nWhat excites me about consoles is that it\u2019s like looking at what might be available to us in future browsers. As well as thinking about how our sites work on small screens, we should also consider big screens. We\u2019re already figuring out how images should work at different screen widths and connection speeds, but we\u2019ve also got some interesting challenges ahead of us catering for second screen experiences and 3D-enabled devices. \n\nSo, this Christmas, if you\u2019re huddled round the game console or a smart TV, give the browser in it a try.", "year": "2012", "author": "Anna Debenham", "author_slug": "annadebenham", "published": "2012-12-22T00:00:00+00:00", "url": "https://24ways.org/2012/unwrapping-the-wii-u-browser/", "topic": "ux"}
{"rowid": 215, "title": "Teach the CLI to Talk Back", "contents": "The CLI is a daunting tool. It\u2019s quick, powerful, but it\u2019s also incredibly easy to screw things up in \u2013 either with a mistyped command, or a correctly typed command used at the wrong moment. This puts a lot of people off using it, but it doesn\u2019t have to be this way.\nIf you\u2019ve ever interacted with Slack\u2019s Slackbot to set a reminder or ask a question, you\u2019re basically using a command line interface, but it feels more like having a conversation. (My favourite Slack app is Lunch Train which helps with the thankless task of herding colleagues to a particular lunch venue on time.)\nSame goes with voice-operated assistants like Alexa, Siri and Google Home. There are even games, like Lifeline, where you interact with a stranded astronaut via pseudo SMS, and KOMRAD where you chat with a Soviet AI.\nI\u2019m not aiming to build an AI here \u2013 my aspirations are a little more down to earth. What I\u2019d like is to make the CLI a friendlier, more forgiving, and more intuitive tool for new or reluctant users. I want to teach it to talk back.\nInteractive command lines in the wild\nIf you\u2019ve used dev tools in the command line, you\u2019ve probably already used an interactive prompt \u2013 something that asks you questions and responds based on your answers. Here are some examples:\nYeoman\nIf you have Yeoman globally installed, running yo will start a command prompt.\n\nThe prompt asks you what you\u2019d like to do, and gives you options with how to proceed. Seasoned users will run specific commands for these options rather than go through this prompt, but it\u2019s a nice way to start someone off with using the tool.\nnpm\nIf you\u2019re a Node.js developer, you\u2019re probably familiar with typing npm init to initialise a project. This brings up prompts that will populate a package.json manifest file for that project.\n\nThe alternative would be to expect the user to craft their own package.json, which is more error-prone since it\u2019s in JSON format, so something as trivial as an extraneous comma can throw an error.\nSnyk\nSnyk is a dev tool that checks for known vulnerabilities in your dependencies. Running snyk wizard in the CLI brings up a list of all the known vulnerabilities, and gives you options on how to deal with it \u2013 such as patching the issue, applying a fix by upgrading the problematic dependency, or ignoring the issue (you are then prompted for a reason).\n\nThese decisions get mapped to the manifest and a .snyk file, and committed into the repo so that the settings are the same for everyone who uses that project.\nI work at Snyk, and running the wizard is what made me think about building my own personal assistant in the command line to help me with some boring, repetitive tasks.\nWriting your own\nSomething I do a lot is add bookmarks to styleguides.io \u2013 I pull down the entire repo, copy and paste a template YAML file, and edit to contents. Sometimes I get it wrong and break the site. So I\u2019ve been putting together a tool to help me add bookmarks.\nIt\u2019s called bookmarkbot \u2013 it\u2019s a personal assistant squirrel called Mark who will collect and bury your bookmarks for safekeeping.*\n\n*Fortunately, this metaphor also gives me a charming excuse for any situation where bookmarks sometimes get lost \u2013 it\u2019s not my poorly-written code, honest, it\u2019s just being realistic because sometimes squirrels forget where they buried things!\nWhen you run bookmarkbot, it will ask you for some information, and save that information as a Markdown file in YAML format.\nFor this demo, I\u2019m going to use a Node.js package called inquirer, which is a well supported tool for creating command line prompts. I like it because it has a bunch of different question types; from input, which asks for some text back, confirm which expects a yes/no response, or a list which gives you a set of options to choose from. You can even nest questions, Choose Your Own Adventure style.\nPrerequisites\n\nNode.js\nnpm\nRubyGems (Only if you want to go as far as serving a static site for your bookmarks, and you want to use Jekyll for it)\n\nDisclaimer\nBear in mind that this is a really simplified walkthrough. It doesn\u2019t have any error states, and it doesn\u2019t handle the situation where we save a file with the same name. But it gets you in a good place to start building out your tool.\nLet\u2019s go!\nCreate a new folder wherever you keep your projects, and give it an awesome name (I\u2019ve called mine bookmarks and put it in the Sites directory because I\u2019m unimaginative). Now cd to that directory. \ncd Sites/bookmarks\nLet\u2019s use that example I gave earlier, the trusty npm init.\nnpm init\nPop in the information you\u2019d like to provide, or hit ENTER to skip through and save the defaults. Your directory should now have a package.json file in it. Now let\u2019s install some of the dependencies we\u2019ll need.\nnpm install --save inquirer\nnpm install --save slugify\nNext, add the following snippet to your package.json to tell it to run this file when you run npm start.\n\"scripts\": {\n  \u2026\n  \"start\": \"node index.js\"\n}\nThat index.js file doesn\u2019t exist yet, so let\u2019s create it in the root of our folder, and add the following:\n// Packages we need\nvar fs = require('fs'); // Creates our file (part of Node.js so doesn't need installing)\nvar inquirer = require('inquirer'); // The engine for our questions prompt\nvar slugify = require('slugify'); // Will turn a string into a usable filename\n\n// The questions\nvar questions = [\n  {\n    type: 'input',\n    name: 'name',\n    message: 'What is your name?',\n  },\n];\n\n// The questions prompt\nfunction askQuestions() {\n\n  // Ask questions\n  inquirer.prompt(questions).then(answers => {\n\n    // Things we'll need to generate the output\n    var name = answers.name;\n\n    // Finished asking questions, show the output\n    console.log('Hello ' + name + '!');\n\n  });\n\n}\n\n// Kick off the questions prompt\naskQuestions();\nThis is just some barebones where we\u2019re including the inquirer package we installed earlier. I\u2019ve stored the questions in a variable, and the askQuestions function will prompt the user for their name, and then print \u201cHello <your name>\u201d in the console.\nEnough setup, let\u2019s see some magic. Save the file, go back to the command line and run npm start.\n\nExtending what we\u2019ve learnt\nAt the moment, we\u2019re just saving a name to a file, which isn\u2019t really achieving our goal of saving bookmarks. We don\u2019t want our tool to forget our information every time we talk to it \u2013 we need to save it somewhere. So I\u2019m going to add a little function to write the output to a file.\nSaving to a file\nCreate a folder in your project\u2019s directory called _bookmarks. This is where the bookmarks will be saved.\nI\u2019ve replaced my questions array, and instead of asking for a name, I\u2019ve extended out the questions, asking to be provided with a link and title (as a regular input type), a list of tags (using inquirer\u2019s checkbox type), and finally a description, again, using the input type.\nSo this is how my code looks now:\n// Packages we need\nvar fs = require('fs'); // Creates our file\nvar inquirer = require('inquirer'); // The engine for our questions prompt\nvar slugify = require('slugify'); // Will turn a string into a usable filename\n\n// The questions\nvar questions = [\n  {\n    type: 'input',\n    name: 'link',\n    message: 'What is the url?',\n  },\n  {\n    type: 'input',\n    name: 'title',\n    message: 'What is the title?',\n  },\n  {\n    type: 'checkbox',\n    name: 'tags',\n    message: 'Would you like me to add any tags?',\n    choices: [\n      { name: 'frontend' },\n      { name: 'backend' },\n      { name: 'security' },\n      { name: 'design' },\n      { name: 'process' },\n      { name: 'business' },\n    ],\n  },\n  {\n    type: 'input',\n    name: 'description',\n    message: 'How about a description?',\n  },\n];\n\n// The questions prompt\nfunction askQuestions() {\n\n  // Say hello\n  console.log('\ud83d\udc3f  Oh, hello! Found something you want me to bookmark?\\n');\n\n  // Ask questions\n  inquirer.prompt(questions).then((answers) => {\n\n    // Things we'll need to generate the output\n    var title = answers.title;\n    var link = answers.link;\n    var tags = answers.tags + '';\n    var description = answers.description;\n    var output = '---\\n' +\n                 'title: \"' + title + '\"\\n' +\n                 'link: \"' + link + '\"\\n' +\n                 'tags: [' + tags + ']\\n' +\n                 '---\\n' + description + '\\n';\n\n    // Finished asking questions, show the output\n    console.log('\\n\ud83d\udc3f  All done! Here is what I\\'ve written down:\\n');\n    console.log(output);\n\n    // Things we'll need to generate the filename\n    var slug = slugify(title);\n    var filename = '_bookmarks/' + slug + '.md';\n\n    // Write the file\n    fs.writeFile(filename, output, function () {\n      console.log('\\n\ud83d\udc3f  Great! I have saved your bookmark to ' + filename);\n    });\n\n  });\n\n}\n\n// Kick off the questions prompt\naskQuestions();\nThe output is formatted into YAML metadata as a Markdown file, which will allow us to turn it into a static HTML file using a build tool later. Run npm start again and have a look at the file it outputs.\n\nGetting confirmation\nBefore the user makes critical changes, it\u2019s good to verify those changes first. We\u2019re going to add a confirmation step to our tool, before writing the file. More seasoned CLI users may favour speed over a \u201chey, can you wait a sec and just check this is all ok\u201d step, but I always think it\u2019s worth adding one so you can occasionally save someone\u2019s butt.\nSo, underneath our questions array, let\u2019s add a confirmation array.\n// Packages we need\n\u2026\n// The questions\n\u2026\n\n// Confirmation questions\nvar confirm = [\n  {\n    type: 'confirm',\n    name: 'confirm',\n    message: 'Does this look good?',\n  },\n];\n\n// The questions prompt\n\u2026\n\nAs we\u2019re adding the confirm step before the file gets written, we\u2019ll need to add the following inside the askQuestions function:\n// The questions prompt\nfunction askQuestions() {\n  // Say hello\n  \u2026\n  // Ask questions\n  inquirer.prompt(questions).then((answers) => {\n    \u2026\n    // Things we'll need to generate the output\n    \u2026\n    // Finished asking questions, show the output\n    \u2026\n\n    // Confirm output is correct\n    inquirer.prompt(confirm).then(answers => {\n\n      // Things we'll need to generate the filename\n      var slug = slugify(title);\n      var filename = '_bookmarks/' + slug + '.md';\n\n      if (answers.confirm) {\n        // Save output into file\n        fs.writeFile(filename, output, function () {\n          console.log('\\n\ud83d\udc3f  Great! I have saved your bookmark to ' +\n          filename);\n        });\n      } else {\n        // Ask the questions again\n        console.log('\\n\ud83d\udc3f  Oops, let\\'s try again!\\n');\n        askQuestions();\n      }\n\n    });\n\n  });\n}\n\n// Kick off the questions prompt\naskQuestions();\nNow run npm start and give it a go!\n\nTyping y will write the file, and n will take you back to the start. Ideally, I\u2019d store the answers already given as defaults so the user doesn\u2019t have to start from scratch, but I want to keep this demo simple.\nServing the files\nNow that your bookmarking tool is successfully saving formatted Markdown files to a folder, the next step is to serve those files in a way that lets you share them online. The easiest way to do this is to use a static-site generator to convert your YAML files into HTML, and pop them all on one page. Now, you\u2019ve got a few options here and I don\u2019t want to force you down any particular path, as there are plenty out there \u2013 it\u2019s just a case of using the one you\u2019re most comfortable with.\nI personally favour Jekyll because of its tight integration with GitHub Pages \u2013 I don\u2019t want to mess around with hosting and deployment, so it\u2019s really handy to have my bookmarks publish themselves on my site as soon as I commit and push them using Git.\nI\u2019ll give you a very brief run-through of how I\u2019m doing this with bookmarkbot, but I recommend you read my Get Started With GitHub Pages (Plus Bonus Jekyll) guide if you\u2019re unfamiliar with them, because I\u2019ll be glossing over some bits that are already covered in there.\nSetting up a build tool\nIf you haven\u2019t already, install Jekyll and Bundler globally through RubyGems. Jekyll is our static-site generator, and Bundler is what we use to install Ruby dependencies.\ngem install jekyll bundler\nIn my project folder, I\u2019m going to run the following which will install the Jekyll files we\u2019ll need to build our listing page. I\u2019m using --force, otherwise it will complain that the directory isn\u2019t empty.\njekyll new . --force\nIf you check your project folder, you\u2019ll see a bunch of new files. Now run the following to start the server:\nbundle exec jekyll serve\nThis will build a new directory called _site. This is where your static HTML files have been generated. Don\u2019t touch anything in this folder because it will get overwritten the next time you build.\nNow that serve is running, go to http://127.0.0.1:4000/ and you\u2019ll see the default Jekyll page and know that things are set up right. Now, instead, we want to see our list of bookmarks that are saved in the _bookmarks directory (make sure you\u2019ve got a few saved). So let\u2019s get that set up next.\nOpen up the _config.yml file that Jekyll added earlier. In here, we\u2019re going to tell it about our bookmarks. Replace everything in your _config.yml file with the following:\ntitle: My Bookmarks\ndescription: These are some of my favourite articles about the web.\nmarkdown: kramdown\nbaseurl: /bookmarks # This needs to be the same name as whatever you call your repo on GitHub.\ncollections:\n  - bookmarks\nThis will make Jekyll aware of our _bookmarks folder so that we can call it later. Next, create a new directory and file at _layouts/home.html and paste in the following.\n<!doctype html>\n<html lang=\"en\">\n<head>\n  <meta charset=\"UTF-8\" />\n  <title>{{site.title}}</title>\n  <meta name=\"description\" content=\"{{site.description}}\">\n</head>\n\n<body>\n\n  <h1>{{site.title}}</h1>\n  <p>{{site.description}}</p>\n\n  <ul>\n    {% for bookmark in site.bookmarks %}\n    <li>\n      <a href=\"{{bookmark.link}}\">\n        <h2>{{bookmark.title}}</h2>\n      </a>\n      {{bookmark.content}}\n      {% if bookmark.tags %}\n      <ul>\n        {% for tags in bookmark.tags %}<li>{{tags}}</li>{% endfor %}\n      </ul>\n      {% endif %}\n    </li>\n    {% endfor %}\n  </ul>\n\n</body>\n\n</html>\nRestart Jekyll for your config changes to kick in, and go to the url it provides you (probably http://127.0.0.1:4000/bookmarks, unless you gave something different as your baseurl).\n\nIt\u2019s a decent start \u2013 there\u2019s a lot more we can do in this area but now we\u2019ve got a nice list of all our bookmarks, let\u2019s get it online!\nIf you want to use GitHub Pages to host your files, your first step is to push your project to GitHub. Go to your repository and click \u201csettings\u201d. Scroll down to the section labelled \u201cGitHub Pages\u201d, and from here you can enable it. Select your master branch, and it will provide you with a url to view your published pages.\n\nWhat next?\nNow that you\u2019ve got a framework in place for publishing bookmarks, you can really go to town on your listing page and make it your own. First thing you\u2019ll probably want to do is add some CSS, then when you\u2019ve added a bunch of bookmarks, you\u2019ll probably want to have some filtering in place for the tags, perhaps extend the types of questions that you ask to include an image (if you\u2019re feeling extra-fancy, you could just ask for a url and pull in metadata from the site itself). Maybe you\u2019ve got an idea that doesn\u2019t involve bookmarks at all.\nYou could use what you\u2019ve learnt to build a place where you can share quotes, a list of your favourite restaurants, or even Christmas gift ideas.\nHere\u2019s one I made earlier\n\nMy demo, bookmarkbot, is on GitHub, and I\u2019ve reused a lot of the code from styleguides.io.

{"rowid": 147, "title": "Christmas Is In The AIR", "contents": "That\u2019s right, Christmas is coming up fast and there\u2019s plenty of things to do. Get the tree and lights up, get the turkey, buy presents and who know what else. And what about Santa? He\u2019s got a list. I\u2019m pretty sure he\u2019s checking it twice.\n\nSure, we could use an existing list making web site or even a desktop widget. But we\u2019re geeks! What\u2019s the fun in that? Let\u2019s build our own to-do list application and do it with Adobe AIR!\n\nWhat\u2019s Adobe AIR?\n\nAdobe AIR, formerly codenamed Apollo, is a runtime environment that runs on both Windows and OSX (with Linux support to follow). This runtime environment lets you build desktop applications using Adobe technologies like Flash and Flex. Oh, and HTML. That\u2019s right, you web standards lovin\u2019 maniac. You can build desktop applications that can run cross-platform using the trio of technologies, HTML, CSS and JavaScript.\n\nIf you\u2019ve tried developing with AIR before, you\u2019ll need to get re-familiarized with the latest beta release as many things have changed since the last one (such as the API and restrictions within the sandbox.)\n\nTo get started\n\nTo get started in building an AIR application, you\u2019ll need two basic things:\n\n\n\tThe AIR runtime. The runtime is needed to run any AIR-based application.\n\tThe SDK. The software development kit gives you all the pieces to test your application. Unzip the SDK into any folder you wish.\n\n\nYou\u2019ll also want to get your hands on the JavaScript API documentation which you\u2019ll no doubt find yourself getting into before too long. (You can download it, too.)\n\nAlso of interest, some development environments have support for AIR built right in. Aptana doesn\u2019t have support for beta 3 yet but I suspect it\u2019ll be available shortly.\n\nWithin the SDK, there are two main tools that we\u2019ll use: one to test the application (ADL) and another to build a distributable package of our application (ADT). I\u2019ll get into this some more when we get to that stage of development.\n\nBuilding our To-do list application\n\nThe first step to building an application within AIR is to create an XML file that defines our default application settings. I call mine application.xml, mostly because Aptana does that by default when creating a new AIR project. It makes sense though and I\u2019ve stuck with it. Included in the templates folder of the SDK is an example XML file that you can use.\n\nThe first key part to this after specifying things like the application ID, version, and filename, is to specify what the default content should be within the content tags. Enter in the name of the HTML file you wish to load. Within this HTML file will be our application.\n\n<content>ui.html</content>\n\nCreate a new HTML document and name it ui.html and place it in the same directory as the application.xml file. The first thing you\u2019ll want to do is copy over the AIRAliases.js file from the frameworks folder of the SDK and add a link to it within your HTML document.\n\n<script type=\"text/javascript\" src=\"AIRAliases.js\"></script>\n\nThe aliases create shorthand links to all of the Flash-based APIs.\n\nNow is probably a good time to explain how to debug your application.\n\nDebugging our application\n\nSo, with our XML file created and HTML file started, let\u2019s try testing our \u2018application\u2019. We\u2019ll need the ADL application located in BIN folder of the SDK and tell it to run the application.xml file.\n\n/path/to/adl /path/to/application.xml\n\nYou can also just drag the XML file onto ADL and it\u2019ll accomplish the same thing. If you just did that and noticed that your blank application didn\u2019t load, you\u2019d be correct. It\u2019s running but isn\u2019t visible. Which at this point means you\u2019ll have to shut down the ADL process. Sorry about that!\n\nChanging the visibility\n\nYou have two ways to make your application visible. You can do it automatically by setting the placing true in the visible tag within the application.xml file.\n\n<visible>true</visible>\n\nThe other way is to do it programmatically from within your application. You\u2019d want to do it this way if you had other startup tasks to perform before showing the interface. To turn the UI on programmatically, simple set the visible property of nativeWindow to true.\n\n<script type=\"text/javascript\">\n\tnativeWindow.visible = true;\n</script>\n\nSandbox Security\n\nNow that we have an application that we can see when we start it, it\u2019s time to build the to-do list application. In doing so, you\u2019d probably think that using a JavaScript library is a really good idea \u2014 and it can be but there are some limitations within AIR that have to be considered.\n\nAn HTML document, by default, runs within the application sandbox. You have full access to the AIR APIs but once the onload event of the window has fired, you\u2019ll have a limited ability to make use of eval and other dynamic script injection approaches. This limits the ability of external sources from gaining access to everything the AIR API offers, such as database and local file system access. You\u2019ll still be able to make use of eval for evaluating JSON responses, which is probably the most important if you wish to consume JSON-based services.\n\nIf you wish to create a greater wall of security between AIR and your HTML document loading in external resources, you can create a child sandbox. We won\u2019t need to worry about it for our application so I won\u2019t go any further into it but definitely keep this in mind.\n\nFinally, our application\n\nGetting tired of all this preamble? Let\u2019s actually build our to-do list application. I\u2019ll use jQuery because it\u2019s small and should suit our needs nicely. Let\u2019s begin with some structure:\n\n<body>\n\t<input type=\"text\" id=\"text\" value=\"\">\n\t<input type=\"button\" id=\"add\" value=\"Add\">\n\t<ul id=\"list\"></ul>\n</body>\n\nNow we need to wire up that button to actually add a new item to our to-do list.\n\n<script type=\"text/javascript\">\n$(document).ready(function(){\n\t// make sure the application is visible\n\tnativeWindow.visible = true;\n\t$('#add').click(function(){\n\t\tvar t = $('#text').val();\n\t\tif(t)\n\t\t{\n\t\t\t// use DOM methods to create the new list item\n\t\t\tvar li = document.createElement('li');\n\t\t\t// the extra space at the end creates a buffer between the text\n\t\t\t// and the delete link we're about to add\n\t\t\tli.appendChild(document.createTextNode(t + ' '));\n\t\t\t// create the delete link\n\t\t\tvar del = document.createElement('a');\n\t\t\t// this makes it a true link. I feel dirty doing this.\n\t\t\tdel.setAttribute('href', '#');\n\t\t\tdel.addEventListener('click', function(evt){\n\t\t\t\tthis.parentNode.parentNode.removeChild(this.parentNode);\n\t\t\t});\n\t\t\tdel.appendChild(document.createTextNode('[del]'));\n\t\t\tli.appendChild(del);\n\t\t\t// append everything to the list\n\t\t\t$('#list').append(li);\n\t\t\t//reset the text box\n\t\t\t$('#text').val('');\n\t\t}\n\t})\n});\n</script>\n\nAnd just like that, we\u2019ve got a to-do list! That\u2019s it! Just never close your application and you\u2019ll remember everything. Okay, that\u2019s not very practical. You need to have some way of storing your to-do items until the next time you open up the application.\n\nStoring Data\n\nYou\u2019ve essentially got 4 different ways that you can store data:\n\n\n\tUsing the local database. AIR comes with SQLLite built in. That means you can create tables and insert, update and select data from that database just like on a web server.\n\tUsing the file system. You can also create files on the local machine. You have access to a few folders on the local system such as the documents folder and the desktop.\n\tUsing EcryptedLocalStore. I like using the EcryptedLocalStore because it allows you to easily save key/value pairs and have that information encrypted. All this within just a couple lines of code.\n\tSending the data to a remote API. Our to-do list could sync up with Remember the Milk, for example.\n\n\nTo demonstrate some persistence, we\u2019ll use the file system to store our files. In addition, we\u2019ll let the user specify where the file should be saved. This way, we can create multiple to-do lists, keeping them separate and organized.\n\nThe application is now broken down into 4 basic tasks:\n\n\n\tLoad data from the file system.\n\tPerform any interface bindings.\n\tManage creating and deleting items from the list.\n\tSave any changes to the list back to the file system.\n\n\nLoading in data from the file system\n\nWhen the application starts up, we\u2019ll prompt the user to select a file or specify a new to-do list. Within AIR, there are 3 main file objects: File, FileMode, and FileStream. File handles file and path names, FileMode is used as a parameter for the FileStream to specify whether the file should be read-only or for write access. The FileStream object handles all the read/write activity.\n\nThe File object has a number of shortcuts to default paths like the documents folder, the desktop, or even the application store. In this case, we\u2019ll specify the documents folder as the default location and then use the browseForSave method to prompt the user to specify a new or existing file. If the user specifies an existing file, they\u2019ll be asked whether they want to overwrite it.\n\nvar store = air.File.documentsDirectory;\nvar fileStream = new air.FileStream();\nstore.browseForSave(\"Choose To-do List\");\n\nThen we add an event listener for when the user has selected a file. When the file is selected, we check to see if the file exists and if it does, read in the contents, splitting the file on new lines and creating our list items within the interface.\n\nstore.addEventListener(air.Event.SELECT, fileSelected);\nfunction fileSelected()\n{\n\tair.trace(store.nativePath);\n\t// load in any stored data\n\tvar byteData = new air.ByteArray();\n\tif(store.exists)\n\t{\n\t\tfileStream.open(store, air.FileMode.READ);\n\t\tfileStream.readBytes(byteData, 0, store.size);\n\t\tfileStream.close();\n\n\t\tif(byteData.length > 0)\n\t\t{\n\t\t\tvar s = byteData.readUTFBytes(byteData.length);\n\t\t\toldlist = s.split(\u201c\\r\\n\u201d);\n\n\t\t\t// create todolist items\n\t\t\tfor(var i=0; i < oldlist.length; i++)\n\t\t\t{\n\t\t\t\tcreateItem(oldlist[i], (new Date()).getTime() + i );\n\t\t\t}\n\t\t}\n\t}\n}\n\nPerform Interface Bindings\n\nThis is similar to before where we set the click event on the Add button but we\u2019ve moved the code to save the list into a separate function.\n\n$('#add').click(function(){\n\t\tvar t = $('#text').val();\n\t\tif(t){\n\t\t\t// create an ID using the time\n\t\t\tcreateItem(t, (new Date()).getTime() );\n\t\t}\n})\n\nManage creating and deleting items from the list\n\nThe list management is now in its own function, similar to before but with some extra information to identify list items and with calls to save our list after each change.\n\nfunction createItem(t, id)\n{\n\tif(t.length == 0) return;\n\t// add it to the todo list\n\ttodolist[id] = t;\n\t// use DOM methods to create the new list item\n\tvar li = document.createElement('li');\n\t// the extra space at the end creates a buffer between the text\n\t// and the delete link we're about to add\n\tli.appendChild(document.createTextNode(t + ' '));\n\t// create the delete link\n\tvar del = document.createElement('a');\n\t// this makes it a true link. I feel dirty doing this.\n\tdel.setAttribute('href', '#');\n\tdel.addEventListener('click', function(evt){\n\t\tvar id = this.id.substr(1);\n\t\tdelete todolist[id]; // remove the item from the list\n\t\tthis.parentNode.parentNode.removeChild(this.parentNode);\n\t\tsaveList();\n\t});\n\tdel.appendChild(document.createTextNode('[del]'));\n\tdel.id = 'd' + id;\n\tli.appendChild(del);\n\t// append everything to the list\n\t$('#list').append(li);\n\t//reset the text box\n\t$('#text').val('');\n\tsaveList();\n}\n\nSave changes to the file system\n\nAny time a change is made to the list, we update the file. The file will always reflect the current state of the list and we\u2019ll never have to click a save button. It just iterates through the list, adding a new line to each one.\n\nfunction saveList(){\n\tif(store.isDirectory) return;\n\tvar packet = '';\n\tfor(var i in todolist)\n\t{\n\t\tpacket += todolist[i] + '\\r\\n';\n\t}\n\tvar bytes = new air.ByteArray();\n\tbytes.writeUTFBytes(packet);\n\tfileStream.open(store, air.FileMode.WRITE);\n\tfileStream.writeBytes(bytes, 0, bytes.length);\n\tfileStream.close();\n}\n\nOne important thing to mention here is that we check if the store is a directory first. The reason we do this goes back to our browseForSave call. If the user cancels the dialog without selecting a file first, then the store points to the documentsDirectory that we set it to initially. Since we haven\u2019t specified a file, there\u2019s no place to save the list.\n\nHopefully by this point, you\u2019ve been thinking of some cool ways to pimp out your list. Now we need to package this up so that we can let other people use it, too.\n\nCreating a Package\n\nNow that we\u2019ve created our application, we need to package it up so that we can distribute it. This is a two step process. The first step is to create a code signing certificate (or you can pay for one from Thawte which will help authenticate you as an AIR application developer).\n\nTo create a self-signed certificate, run the following command. This will create a PFX file that you\u2019ll use to sign your application.\n\nadt -certificate -cn todo24ways 1024-RSA todo24ways.pfx mypassword\n\nAfter you\u2019ve done that, you\u2019ll need to create the package with the certificate\n\nadt -package -storetype pkcs12 -keystore todo24ways.pfx todo24ways.air application.xml .\n\nThe important part to mention here is the period at the end of the command. We\u2019re telling it to package up all files in the current directory.\n\nAfter that, just run the AIR file, which will install your application and run it.\n\nImportant things to remember about AIR\n\nWhen developing an HTML application, the rendering engine is Webkit. You\u2019ll thank your lucky stars that you aren\u2019t struggling with cross-browser issues. (My personal favourites are multiple backgrounds and border radius!)\n\nBe mindful of memory leaks. Things like Ajax calls and event binding can cause applications to slowly leak memory over time. Web pages are normally short lived but desktop applications are often open for hours, if not days, and you may find your little desktop application taking up more memory than anything else on your machine!\n\nThe WebKit runtime itself can also be a memory hog, usually taking about 15MB just for itself. If you create multiple HTML windows, it\u2019ll add another 15MB to your memory footprint. Our little to-do list application shouldn\u2019t be much of a concern, though.\n\nThe other important thing to remember is that you\u2019re still essentially running within a Flash environment. While you probably won\u2019t notice this working in small applications, the moment you need to move to multiple windows or need to accomplish stuff beyond what HTML and JavaScript can give you, the need to understand some of the Flash-based elements will become more important.\n\nLastly, the other thing to remember is that HTML links will load within the AIR application. If you want a link to open in the users web browser, you\u2019ll need to capture that event and handle it on your own. The following code takes the HREF from a clicked link and opens it in the default web browser.\n\nair.navigateToURL(new air.URLRequest(this.href));\n\nOnly the beginning\n\nOf course, this is only the beginning of what you can do with Adobe AIR. You don\u2019t have the same level of control as building a native desktop application, such as being able to launch other applications, but you do have more control than what you could have within a web application. Check out the Adobe AIR Developer Center for HTML and Ajax for tutorials and other resources.\n\nNow, go forth and create your desktop applications and hopefully you finish all your shopping before Christmas!\n\nDownload the example files.", "year": "2007", "author": "Jonathan Snook", "author_slug": "jonathansnook", "published": "2007-12-19T00:00:00+00:00", "url": "https://24ways.org/2007/christmas-is-in-the-air/", "topic": "code"}
{"rowid": 55, "title": "How Tabs Should Work", "contents": "Tabs in browsers (not browser tabs) are one of the oldest custom UI elements in a browser that I can think of. They\u2019ve been done to death. But, sadly, most of the time I come across them, the tabs have been badly, or rather partially, implemented.\nSo this post is my definition of how a tabbing system should work, and one approach of implementing that.\nBut\u2026 tabs are easy, right?\nI\u2019ve been writing code for tabbing systems in JavaScript for coming up on a decade, and at one point I was pretty proud of how small I could make the JavaScript for the tabbing system:\nvar tabs = $('.tab').click(function () {\n  tabs.hide().filter(this.hash).show();\n}).map(function () {\n  return $(this.hash)[0];\n});\n\n$('.tab:first').click();\nSimple, right? Nearly fits in a tweet (ignoring the whole jQuery library\u2026). Still, it\u2019s riddled with problems that make it a far from perfect solution.\nRequirements: what makes the perfect tab?\n\nAll content is navigable and available without JavaScript (crawler-compatible and low JS-compatible).\nARIA roles.\nThe tabs are anchor links that:\n\nare clickable\nhave block layout\nhave their href pointing to the id of the panel element\nuse the correct cursor (i.e. cursor: pointer).\n\nSince tabs are clickable, the user can open in a new tab/window and the page correctly loads with the correct tab open.\nRight-clicking (and Shift-clicking) doesn\u2019t cause the tab to be selected.\nNative browser Back/Forward button correctly changes the state of the selected tab (think about it working exactly as if there were no JavaScript in place).\n\nThe first three points are all to do with the semantics of the markup and how the markup has been styled. I think it\u2019s easy to do a good job by thinking of tabs as links, and not as some part of an application. Links are navigable, and they should work the same way other links on the page work.\nThe last three points are JavaScript problems. Let\u2019s investigate that.\nThe shitmus test\nLike a litmus test, here\u2019s a couple of quick ways you can tell if a tabbing system is poorly implemented:\n\nChange tab, then use the Back button (or keyboard shortcut) and it breaks\nThe tab isn\u2019t a link, so you can\u2019t open it in a new tab\n\nThese two basic things are, to me, the bare minimum that a tabbing system should have.\nWhy is this important?\nThe people who push their so-called native apps on users can\u2019t have more reasons why the web sucks. If something as basic as a tab doesn\u2019t work, obviously there\u2019s more ammo to push a closed native app or platform on your users.\nIf you\u2019re going to be a web developer, one of your responsibilities is to maintain established interactivity paradigms. This doesn\u2019t mean don\u2019t innovate. But it does mean: stop fucking up my scrolling experience with your poorly executed scroll effects. </rant> :breath:\nURI fragment, absolute URL or query string?\nA URI fragment (AKA the # hash bit) would be using mysite.com/config#content to show the content panel. A fully addressable URL would be mysite.com/config/content. Using a query string (by way of filtering the page): mysite.com/config?tab=content.\nThis decision really depends on the context of your tabbing system. For something like GitHub\u2019s tabs to view a pull request, it makes sense that the full URL changes.\nFor our problem though, I want to solve the issue when the page doesn\u2019t do a full URL update; that is, your regular run-of-the-mill tabbing system.\nI used to be from the school of using the hash to show the correct tab, but I\u2019ve recently been exploring whether the query string can be used. The biggest reason is that multiple hashes don\u2019t work, and comma-separated hash fragments don\u2019t make any sense to control multiple tabs (since it doesn\u2019t actually link to anything).\nFor this article, I\u2019ll keep focused on using a single tabbing system and a hash on the URL to control the tabs.\nMarkup\nI\u2019m going to assume subcontent, so my markup would look like this (yes, this is a cat demo\u2026):\n<ul class=\"tabs\">\n  <li><a class=\"tab\" href=\"#dizzy\">Dizzy</a></li>\n  <li><a class=\"tab\" href=\"#ninja\">Ninja</a></li>\n  <li><a class=\"tab\" href=\"#missy\">Missy</a></li>\n</ul>\n\n<div id=\"dizzy\">\n  <!-- panel content -->\n</div>\n<div id=\"ninja\">\n  <!-- panel content -->\n</div>\n<div id=\"missy\">\n  <!-- panel content -->\n</div>\nIt\u2019s important to note that in the markup the link used for an individual tab references its panel content using the hash, pointing to the id on the panel. This will allow our content to connect up without JavaScript and give us a bunch of features for free, which we\u2019ll see once we\u2019re on to writing the code.\nURL-driven tabbing systems\nInstead of making the code responsive to the user\u2019s input, we\u2019re going to exclusively use the browser URL and the hashchange event on the window to drive this tabbing system. This way we get Back button support for free.\nWith that in mind, let\u2019s start building up our code. I\u2019ll assume we have the jQuery library, but I\u2019ve also provided the full code working without a library (vanilla, if you will), but it depends on relatively new (polyfillable) tech like classList and dataset (which generally have IE10 and all other browser support).\nNote that I\u2019ll start with the simplest solution, and I\u2019ll refactor the code as I go along, like in places where I keep calling jQuery selectors.\nfunction show(id) {\n  // remove the selected class from the tabs,\n  // and add it back to the one the user selected\n  $('.tab').removeClass('selected').filter(function () {\n    return (this.hash === id);\n  }).addClass('selected');\n\n  // now hide all the panels, then filter to\n  // the one we're interested in, and show it\n  $('.panel').hide().filter(id).show();\n}\n\n$(window).on('hashchange', function () {\n  show(location.hash);\n});\n\n// initialise by showing the first panel\nshow('#dizzy');\nThis works pretty well for such little code. Notice that we don\u2019t have any click handlers for the user and the Back button works right out of the box.\nHowever, there\u2019s a number of problems we need to fix:\n\nThe initialised tab is hard-coded to the first panel, rather than what\u2019s on the URL.\nIf there\u2019s no hash on the URL, all the panels are hidden (and thus broken).\nIf you scroll to the bottom of the example, you\u2019ll find a \u201ctop\u201d link; clicking that will break our tabbing system.\nI\u2019ve purposely made the page long, so that when you click on a tab, you\u2019ll see the page scrolls to the top of the tab. Not a huge deal, but a bit annoying.\n\nFrom our criteria at the start of this post, we\u2019ve already solved items 4 and 5. Not a terrible start. Let\u2019s solve items 1 through 3 next.\nUsing the URL to initialise correctly and protect from breakage\nInstead of arbitrarily picking the first panel from our collection, the code should read the current location.hash and use that if it\u2019s available.\nThe problem is: what if the hash on the URL isn\u2019t actually for a tab?\nThe solution here is that we need to cache a list of known panel IDs. In fact, well-written DOM scripting won\u2019t continuously search the DOM for nodes. That is, when the show function kept calling $('.tab').each(...) it was wasteful. The result of $('.tab') should be cached.\nSo now the code will collect all the tabs, then find the related panels from those tabs, and we\u2019ll use that list to double the values we give the show function (during initialisation, for instance).\n// collect all the tabs\nvar tabs = $('.tab');\n\n// get an array of the panel ids (from the anchor hash)\nvar targets = tabs.map(function () {\n  return this.hash;\n}).get();\n\n// use those ids to get a jQuery collection of panels\nvar panels = $(targets.join(','));\n\nfunction show(id) {\n  // if no value was given, let's take the first panel\n  if (!id) {\n    id = targets[0];\n  }\n  // remove the selected class from the tabs,\n  // and add it back to the one the user selected\n  tabs.removeClass('selected').filter(function () {\n    return (this.hash === id);\n  }).addClass('selected');\n\n  // now hide all the panels, then filter to\n  // the one we're interested in, and show it\n  panels.hide().filter(id).show();\n}\n\n$(window).on('hashchange', function () {\n  var hash = location.hash;\n  if (targets.indexOf(hash) !== -1) {\n    show(hash);\n  }\n});\n\n// initialise\nshow(targets.indexOf(location.hash) !== -1 ? location.hash : '');\nThe core of working out which tab to initialise with is solved in that last line: is there a location.hash? Is it in our list of valid targets (panels)? If so, select that tab.\nThe second breakage we saw in the original demo was that clicking the \u201ctop\u201d link would break our tabs. This was due to the hashchange event firing and the code didn\u2019t validate the hash that was passed. Now this happens, the panels don\u2019t break.\nSo far we\u2019ve got a tabbing system that:\n\nWorks without JavaScript.\nSupports right-click and Shift-click (and doesn\u2019t select in these cases).\nLoads the correct panel if you start with a hash.\nSupports native browser navigation.\nSupports the keyboard.\n\nThe only annoying problem we have now is that the page jumps when a tab is selected. That\u2019s due to the browser following the default behaviour of an internal link on the page. To solve this, things are going to get a little hairy, but it\u2019s all for a good cause.\nRemoving the jump to tab\nYou\u2019d be forgiven for thinking you just need to hook a click handler and return false. It\u2019s what I started with. Only that\u2019s not the solution. If we add the click handler, it breaks all the right-click and Shift-click support.\nThere may be another way to solve this, but what follows is the way I found \u2013 and it works. It\u2019s just a bit\u2026 hairy, as I said.\nWe\u2019re going to strip the id attribute off the target panel when the user tries to navigate to it, and then put it back on once the show code starts to run. This change will mean the browser has nowhere to navigate to for that moment, and won\u2019t jump the page.\nThe change involves the following:\n\nAdd a click handle that removes the id from the target panel, and cache this in a target variable that we\u2019ll use later in hashchange (see point 4).\nIn the same click handler, set the location.hash to the current link\u2019s hash. This is important because it forces a hashchange event regardless of whether the URL actually changed, which prevents the tabs breaking (try it yourself by removing this line).\nFor each panel, put a backup copy of the id attribute in a data property (I\u2019ve called it old-id).\nWhen the hashchange event fires, if we have a target value, let\u2019s put the id back on the panel.\n\nThese changes result in this final code:\n/*global $*/\n\n// a temp value to cache *what* we're about to show\nvar target = null;\n\n// collect all the tabs\nvar tabs = $('.tab').on('click', function () {\n  target = $(this.hash).removeAttr('id');\n\n  // if the URL isn't going to change, then hashchange\n  // event doesn't fire, so we trigger the update manually\n  if (location.hash === this.hash) {\n    // but this has to happen after the DOM update has\n    // completed, so we wrap it in a setTimeout 0\n    setTimeout(update, 0);\n  }\n});\n\n// get an array of the panel ids (from the anchor hash)\nvar targets = tabs.map(function () {\n  return this.hash;\n}).get();\n\n// use those ids to get a jQuery collection of panels\nvar panels = $(targets.join(',')).each(function () {\n  // keep a copy of what the original el.id was\n  $(this).data('old-id', this.id);\n});\n\nfunction update() {\n  if (target) {\n    target.attr('id', target.data('old-id'));\n    target = null;\n  }\n\n  var hash = window.location.hash;\n  if (targets.indexOf(hash) !== -1) {\n    show(hash);\n  }\n}\n\nfunction show(id) {\n  // if no value was given, let's take the first panel\n  if (!id) {\n    id = targets[0];\n  }\n  // remove the selected class from the tabs,\n  // and add it back to the one the user selected\n  tabs.removeClass('selected').filter(function () {\n    return (this.hash === id);\n  }).addClass('selected');\n\n  // now hide all the panels, then filter to\n  // the one we're interested in, and show it\n  panels.hide().filter(id).show();\n}\n\n$(window).on('hashchange', update);\n\n// initialise\nif (targets.indexOf(window.location.hash) !== -1) {\n  update();\n} else {\n  show();\n}\nThis version now meets all the criteria I mentioned in my original list, except for the ARIA roles and accessibility. Getting this support is actually very cheap to add.\nARIA roles\nThis article on ARIA tabs made it very easy to get the tabbing system working as I wanted.\nThe tasks were simple:\n\nAdd aria-role set to tab for the tabs, and tabpanel for the panels.\nSet aria-controls on the tabs to point to their related panel (by id).\nI use JavaScript to add tabindex=0 to all the tab elements.\nWhen I add the selected class to the tab, I also set aria-selected to true and, inversely, when I remove the selected class I set aria-selected to false.\nWhen I hide the panels I add aria-hidden=true, and when I show the specific panel I set aria-hidden=false.\n\nAnd that\u2019s it. Very small changes to get full sign-off that the tabbing system is bulletproof and accessible.\nCheck out the final version (and the non-jQuery version as promised).\nIn conclusion\nThere\u2019s a lot of tab implementations out there, but there\u2019s an equal amount that break the browsing paradigm and the simple linkability of content. Clearly there\u2019s a special hell for those tab systems that don\u2019t even use links, but I think it\u2019s clear that even in something that\u2019s relatively simple, it\u2019s the small details that make or break the user experience.\nObviously there are corners I\u2019ve not explored, like when there\u2019s more than one set of tabs on a page, and equally whether you should deliver the initial markup with the correct tab selected. I think the answer lies in using query strings in combination with hashes on the URL, but maybe that\u2019s for another year!", "year": "2015", "author": "Remy Sharp", "author_slug": "remysharp", "published": "2015-12-22T00:00:00+00:00", "url": "https://24ways.org/2015/how-tabs-should-work/", "topic": "code"}
{"rowid": 148, "title": "Typesetting Tables", "contents": "Tables have suffered in recent years on the web. They were used for laying out web pages. Then, following the Web Standards movement, they\u2019ve been renamed by the populous as `data tables\u2019 to ensure that we all know what they\u2019re for. There have been some great tutorials for the designing tables using CSS for presentation and focussing on the semantics in the displaying of data in the correct way. However, typesetting tables is a subtle craft that has hardly had a mention.\n\nTable design can often end up being a technical exercise. What data do we need to display? Where is the data coming from and what form will it take? When was the last time your heard someone talk about lining numerals? Or designing to the reading direction?\n\nTables are not read like sentences\n\nWhen a reader looks at, and tries to understand, tabular data, they\u2019re doing a bunch of things at the same time.\n\n\n\tGenerally, they\u2019re task based; they\u2019re looking for something.\n\tThey are reading horizontally AND vertically\n\n\nReading a table is not like reading a paragraph in a novel, and therefore shouldn\u2019t be typeset in the same way. Designing tables is information design, it\u2019s functional typography\u2014it\u2019s not a time for eye candy.\n\nTypesetting tables\n\nTypesetting great looking tables is largely an exercise in restraint. Minimal interference with the legibility of the table should be in the forefront of any designers mind.\n\nWhen I\u2019m designing tables I apply some simple rules:\n\n\n\tPlenty of negative space\n\tUse the right typeface\n\tGo easy on the background tones, unless you\u2019re giving reading direction visual emphasis\n\tDesign to the reading direction\n\n\nBy way of explanation, here are those rules as applied to the following badly typeset table.\n\nYour default table\n\nThis table is a mess. There is no consideration for the person trying to read it. Everything is too tight. The typeface is wrong. It\u2019s flat. A grim table indeed.\n\n\n\nLet\u2019s see what we can do about that.\n\nPlenty of negative space\n\nThe badly typeset table has been set with default padding. There has been little consideration for the ascenders and descenders in the type interfering with the many horizontal rules.\n\nThe first thing we do is remove most of the lines, or rules. You don\u2019t need them \u2013 the data in the rows forms its own visual rules. Now, with most of the rules removed, the ones that remain mean something; they are indicating some kind of hierarchy to the help the reader understand what the different table elements mean \u2013 in this case the column headings.\n\n\n\nNow we need to give the columns and rows more negative space. Note the framing of the column headings. I\u2019m giving them more room at the bottom. This negative space is active\u2014it\u2019s empty for a reason. The extra air in here also gives more hierarchy to the column headings.\n\n\n\nUse the right typeface\n\nThe default table is set in a serif typeface. This isn\u2019t ideal for a couple of reasons. This serif typeface has a standard set of text numerals. These dip below the baseline and are designed for using figures within text, not on their own. What you need to use is a typeface with lining numerals. These align to the baseline and are more legible when used for tables.\n\n\n\nSans serif typefaces generally have lining numerals. They are also arguably more legible when used in tables.\n\nGo easy on the background tones, unless you\u2019re giving reading direction visual emphasis \n\nWe\u2019ve all seen background tones on tables. They have their use, but my feeling is that use should be functional and not decorative.\n\nIf you have a table that is long, but only a few columns wide, then alternate row shading isn\u2019t that useful for showing the different lines of data. It\u2019s a common misconception that alternate row shading is to increase legibility on long tables. That\u2019s not the case. Shaded rows are to aid horizontal reading across multiple table columns. On wide tables they are incredibly useful for helping the reader find what they want.\n\n\n\nBackground tone can also be used to give emphasis to the reading direction. If we want to emphasis a column, that can be given a background tone.\n\n\n\nHierarchy\n\nAs I said earlier, people may be reading a table vertically, and horizontally in order to find what they want. Sometimes, especially if the table is complex, we need to give them a helping hand.\n\nVisually emphasising the hierarchy in tables can help the reader scan the data. Column headings are particularly important. Column headings are often what a reader will go to first, so we need to help them understand that the column headings are different to the stuff beneath them, and we also need to give them more visual importance. We can do this by making them bold, giving them ample negative space, or by including a thick rule above them. We can also give the row titles the same level of emphasis.\n\n\n\nIn addition to background tones, you can give emphasis to reading direction by typesetting those elements in bold. You shouldn\u2019t use italics\u2014with sans serif typefaces the difference is too subtle.\n\nSo, there you have it. A couple of simple guidelines to make your tables cleaner and more readable.", "year": "2007", "author": "Mark Boulton", "author_slug": "markboulton", "published": "2007-12-07T00:00:00+00:00", "url": "https://24ways.org/2007/typesetting-tables/", "topic": "design"}
{"rowid": 219, "title": "Speed Up Your Site with Delayed Content", "contents": "Speed remains one of the most important factors influencing the success of any website, and the first rule of performance (according to Yahoo!) is reducing the number of HTTP requests. Over the last few years we\u2019ve seen techniques like sprites and combo CSS/JavaScript files used to reduce the number of HTTP requests. But there\u2019s one area where large numbers of HTTP requests are still a fact of life: the small avatars attached to the comments on articles like this one.\n\nAvatars\n\nMany sites like 24 ways use a fantastic service called Gravatar to provide user images. As a user, you can sign up to Gravatar, give them your e-mail address, and upload an image to represent you. Sites can then include your image by generating a one way hash of your e-mail address and using that to build an image URL. For example, the markup for the comments on this page looks something like this:\n\n<div>\n\t<h4><a href=\"http://allinthehead.com/\">\n\t\t<img src=\"http://www.gravatar.com/avatar.php?gravatar_id=13734b0cb20708f79e730809c29c3c48&size=100\" class=\"gravatar\" alt=\"\" height=\"100\" width=\"100\" />\n    Drew McLellan\n\t</a></h4>\n\t<p>This is a great article!</p>\n</div>\n\nThe Gravatar URL contains two parts. 100 is the size in pixels of the image we want.  13734b0cb20708f79e730809c29c3c48 is an MD5 digest of Drew\u2019s e-mail address. Using MD5 means we can request an image for a user without sharing their e-mail address with anyone who views the source of the page.\n\nSo what\u2019s wrong with avatars?\n\nThe problem is that a popular article can easily get hundreds of comments, and every one of them means another image has to be individually requested from Gravatar\u2019s servers. Each request is small and the Gravatar servers are fast but, when you add them up, it can easily add seconds to the rendering time of a page. Worse, they can delay the loading of more important assets like the CSS required to render the main content of the page.\n\nThese images aren\u2019t critical to the page, and don\u2019t need to be loaded up front. Let\u2019s see if we can delay loading them until everything else is done. That way we can give the impression that our site has loaded quickly even if some requests are still happening in the background.\n\nDelaying image loading\n\nThe first problem we find is that there\u2019s no way to prevent Internet Explorer, Chrome or Safari from loading an image without removing it from the HTML itself. Tricks like removing the images on the fly with JavaScript don\u2019t work, as the browser has usually started requesting the images before we get a chance to stop it.\n\nRemoving the images from the HTML means that people without JavaScript enabled in their browser won\u2019t see avatars. As Drew mentioned at the start of the month, this can affect a large number of people, and we can\u2019t completely ignore them. But most sites already have a textual name attached to each comment and the avatars are just a visual enhancement. In most cases it\u2019s OK if some of our users don\u2019t see them, especially if it speeds up the experience for the other 98%.\n\nRemoving the images from the source of our page also means we\u2019ll need to put them back at some point, so we need to keep a record of which images need to be requested. All Gravatar images have the same URL format; the only thing that changes is the e-mail hash. Storing this is a great use of HTML5 data attributes.\n\nHTML5 data what?\n\nData attributes are a new feature in HTML5. The latest version of the spec says:\n\n\n\tA custom data attribute is an attribute in no namespace whose name starts with the string \u201cdata-\u201d, has at least one character after the hyphen, is XML-compatible, and contains no characters in the range U+0041 to U+005A (LATIN CAPITAL LETTER A to LATIN CAPITAL LETTER Z).\n[\u2026]\nCustom data attributes are intended to store custom data private to the page or application, for which there are no more appropriate attributes or elements. These attributes are not intended for use by software that is independent of the site that uses the attributes.\n\n\nIn other words, they\u2019re attributes of an HTML element that start with \u201cdata-\u201d which you can use to share data with scripts running on your site. They\u2019re great for adding small bits of metadata that don\u2019t fit into an existing markup pattern the way microformats do.\n\nLet\u2019s see this in action\n\nTake a look at the markup for comments again:\n\n<div>\n\t<h4><a href=\"http://allinthehead.com/\">\n\t\t<img src=\"http://www.gravatar.com/avatar.php?gravatar_id=13734b0cb20708f79e730809c29c3c48&size=100\" class=\"gravatar\" alt=\"\" height=\"100\" width=\"100\" />\n    Drew McLellan\n\t</a></h4>\n\t<p>This is a great article!</p>\n</div>\n\nLet\u2019s replace the <img> element with a data-gravatar-hash attribute on the <a> element:\n\n<div>\n\t<h4><a href=\"http://allinthehead.com/\" data-gravatar-hash=\"13734b0cb20708f79e730809c29c3c48\">\n    Drew McLellan\n\t</a></h4>\n\t<p>This is a great article!</p>\n</div>\n\nOnce we\u2019ve done this, we\u2019ll need a small bit of JavaScript to find all these attributes, and replace them with images after the page has loaded. Here\u2019s an example using jQuery:\n\n$(window).load(function() {\n\t$('a[data-gravatar-hash]').prepend(function(index){\n\t\tvar hash = $(this).attr('data-gravatar-hash')\n\t\treturn '<img width=\"100\" height=\"100\" alt=\"\" src=\"http://www.gravatar.com/avatar.php?size=100&gravatar_id=' + hash + '\">'\n\t})\n})\n\nThis code waits until everything on the page is loaded, then uses jQuery.prepend to insert an image into every link containing a data-gravatar-hash attribute. It\u2019s short and relatively simple, but in tests it reduced the rendering time of a sample page from over three seconds to well under one.\n\nFinishing touches\n\nWe still need to consider the appearance of the page before the avatars have loaded. When our script adds extra content to the page it will cause a browser reflow, which is visually annoying. We can avoid this by using CSS to reserve some space for each image before it\u2019s inserted into the HTML:\n\n#comments div {\n\tpadding-left: 110px;\n\tmin-height: 100px;\n\tposition: relative;\n}\n#comments div h4 img {\n\tdisplay: block;\n\tposition: absolute;\n\ttop: 0;\n\tleft: 0;\n}\n\nIn a real world example, we\u2019ll also find that the HTML for a comment is more varied as many users don\u2019t provide a web page link. We can make small changes to our JavaScript and CSS to handle this case.\n\nPut this all together and you get this example.\n\nTaking this idea further\n\nThere\u2019s no reason to limit this technique to sites using Gravatar; we can use similar code to delay loading any images that don\u2019t need to be present immediately. For example, this year\u2019s redesigned Flickr photo page uses a \u201cdata-defer-src\u201d attribute to describe any image that doesn\u2019t need to be loaded straight away, including avatars and map tiles.\n\nYou also don\u2019t have to limit yourself to loading the extra resources once the page loads. You can get further bandwidth savings by waiting until the user takes an action before downloading extra assets. Amazon has taken this tactic to the extreme on its product pages \u2013 extra content is loaded as you scroll down the page.\n\nSo next time you\u2019re building a page, take a few minutes to think about which elements are peripheral and could be delayed to allow more important content to appear as quickly as possible.", "year": "2010", "author": "Paul Hammond", "author_slug": "paulhammond", "published": "2010-12-18T00:00:00+00:00", "url": "https://24ways.org/2010/speed-up-your-site-with-delayed-content/", "topic": "ux"}
{"rowid": 81, "title": "Science!", "contents": "Sometimes we want to capture people\u2019s 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\u2019ll forgive a little flowery festive flourish).\n\nI 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\u2019t accidentally disrupt. If that seems to make sense to you, then you\u2019ll find the following snippets of science as useful as I did.\n\nSaccades and fixations\n\nAs you\u2019re 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 \u2014 fast \u2014 in around a quarter of a second.\n\nThe jumps are called saccades. The pauses are called fixations. Sometimes we take regressive saccades, skipping back to reread. There\u2019s a simple example in the excellent little book, Detail in Typography, by Jost Hochuli.\n\n\n\nIf you want to explore the science of reading in much more depth, I recommend the excellent paper, \u201cThe Science of Word Recognition\u201d, by Dr Kevin Larson of Microsoft.\n\nTo design for legibility and readability is to design for saccades and fixations. It\u2019s the craft of making it easy for people\u2019s brains to extract meaning, using techniques like good contrast, font size, spacing and structure, and only interrupting the reading experience deliberately.\n\nScan paths\n\nAt 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\u2019re 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\u2019s Le\u00e7on d\u2019anatomie:\n\n\n\nFor websites, the scan path is a little different. This is an aggregate scan path of Google from LC Technologies:\n\n\n\nThe 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:\n\n\n\nJust 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.\n\nDesigning for scan paths is to organise content to help people move through an interface to get orientated, and to read.\n\nThe elements that are important enough to need impact must interrupt the scan path and clearly call attention to themselves. However, they don\u2019t 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.\n\nSwinging mood\n\nHuman beings are resilient. Among the immersion and occasional interruptions, we even like a little disruption, especially if it\u2019s absurd and funny. The Ling\u2019s Cars website proves it. In fact, we\u2019re so resilient that we can work around all kinds of mayhem to get a seemingly simple task done.\n\nIn one study, \u201cThe Aesthetics of Reading\u201d (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.\n\n\n\nThey engaged twenty volunteers \u2014 half male, half female \u2014 and showed the good version to half of the participants. The other half saw the poor version.\n\nThe good doctors found that, \u201cthere are important differences between good and poor typography that appear to have little effect on common performance measures such as reading speed and comprehension.\u201d In short, good typography didn\u2019t help people read faster or comprehend better.\n\nOh. On the face of it that seems to invalidate what we designers do. Hold your horses, though! They also found that \u201cthe participants who received the good typography performed better on relative subjective duration and on certain cognitive tasks\u201d, and that \u201cgood typography induces a good mood.\u201d\n\nThis 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.\n\nThat 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\u2019re having fun!\n\n\n\nSource: Nationaal Archief of the Netherlands: Cheering man after the first goal, Netherlands vs. Belgium, Amsterdam, 1931.\n\nSo, 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.

{"rowid": 252, "title": "Turn Jekyll up to Eleventy", "contents": "Sometimes it pays not to over complicate things. While many of the sites we use on a daily basis require relational databases to manage their content and dynamic pages to respond to user input, for smaller, simpler sites, serving pre-rendered static HTML is usually a much cheaper \u2014 and more secure \u2014 option. \nThe JAMstack (JavaScript, reusable APIs, and prebuilt Markup) is a popular marketing term for this way of building websites, but in some ways it\u2019s a return to how things were in the early days of the web, before developers started tinkering with CGI scripts or Personal HomePage. Indeed, my website has always served pre-rendered HTML; first with the aid of Movable Type and more recently using Jekyll, which Anna wrote about in 2013.\nBy combining three approachable languages \u2014 Markdown for content, YAML for data and Liquid for templating \u2014 the ergonomics of Jekyll found broad appeal, influencing the design of the many static site generators that followed. But Jekyll is not without its faults. Aside from notoriously slow build times, it\u2019s also built using Ruby. While this is an elegant programming language, it is yet another ecosystem to understand and manage, and often alongside one we already use: JavaScript. For all my time using Jekyll, I would think to myself \u201cthis, but in Node\u201d. Thankfully, one of Santa\u2019s elves (Zach Leatherman) granted my Atwoodian wish and placed such a static site generator under my tree.\nIntroducing Eleventy\nEleventy is a more flexible alternative Jekyll. Besides being written in Node, it\u2019s less strict about how to organise files and, in addition to Liquid, supports other templating languages like EJS, Pug, Handlebars and Nunjucks. Best of all, its build times are significantly faster (with future optimisations promising further gains).\nAs content is saved using the familiar combination of YAML front matter and Markdown, transitioning from Jekyll to Eleventy may seem like a reasonable idea. Yet as I\u2019ve discovered, there are a few gotchas. If you\u2019ve been considering making the switch, here are a few tips and tricks to help you on your way1.\nNote: Throughout this article, I\u2019ll be converting Matt Cone\u2019s Markdown Guide site as an example. If you want to follow along, start by cloning the git repository, and then change into the project directory:\ngit clone https://github.com/mattcone/markdown-guide.git\ncd markdown-guide\nBefore you start\nIf you\u2019ve used tools like Grunt, Gulp or Webpack, you\u2019ll be familiar with Node.js but, if you\u2019ve been exclusively using Jekyll to compile your assets as well as generate your HTML, now\u2019s the time to install Node.js and set up your project to work with its package manager, NPM:\n\nInstall Node.js:\n\nMac: If you haven\u2019t already, I recommend installing Homebrew, a package manager for the Mac. Then in the Terminal type brew install node.\nWindows: Download the Windows installer from the Node.js website and follow the instructions.\n\nInitiate NPM: Ensure you are in the directory of your project and then type npm init. This command will ask you a few questions before creating a file called package.json. Like RubyGems\u2019s Gemfile, this file contains a list of your project\u2019s third-party dependencies.\n\nIf you\u2019re managing your site with Git, make sure to add node_modules to your .gitignore file too. Unlike RubyGems, NPM stores its dependencies alongside your project files. This folder can get quite large, and as it contains binaries compiled to work with the host computer, it shouldn\u2019t be version controlled. Eleventy will also honour the contents of this file, meaning anything you want Git to ignore, Eleventy will ignore too.\nInstalling Eleventy\nWith Node.js installed and your project setup to work with NPM, we can now install Eleventy as a dependency:\nnpm install --save-dev @11ty/eleventy\nIf you open package.json you should see the following:\n\u2026\n\"devDependencies\": {\n  \"@11ty/eleventy\": \"^0.6.0\"\n}\n\u2026\nWe can now run Eleventy from the command line using NPM\u2019s npx command. For example, to covert the README.md file to HTML, we can run the following:\nnpx eleventy --input=README.md --formats=md\nThis command will generate a rendered HTML file at _site/README/index.html. Like Jekyll, Eleventy shares the same default name for its output directory (_site), a pattern we will see repeatedly during the transition.\nConfiguration\nWhereas Jekyll uses the declarative YAML syntax for its configuration file, Eleventy uses JavaScript. This allows its options to be scripted, enabling some powerful possibilities as we\u2019ll see later on.\nWe\u2019ll start by creating our configuration file (.eleventy.js), copying the relevant settings in _config.yml over to their equivalent options:\nmodule.exports = function(eleventyConfig) {\n  return {\n    dir: {\n      input: \"./\",      // Equivalent to Jekyll's source property\n      output: \"./_site\" // Equivalent to Jekyll's destination property\n    }\n  };\n};\nA few other things to bear in mind:\n\n\nWhereas Jekyll allows you to list folders and files to ignore under its exclude property, Eleventy looks for these values inside a file called .eleventyignore (in addition to .gitignore).\n\nBy default, Eleventy uses markdown-it to parse Markdown. If your content uses advanced syntax features (such as abbreviations, definition lists and footnotes), you\u2019ll need to pass Eleventy an instance of this (or another) Markdown library configured with the relevant options and plugins.\n\nLayouts\nOne area Eleventy currently lacks flexibility is the location of layouts, which must reside within the _includes directory (see this issue on GitHub).\nWanting to keep our layouts together, we\u2019ll move them from _layouts to _includes/layouts, and then update references to incorporate the layouts sub-folder. We could update the layout: frontmatter property in each of our content files, but another option is to create aliases in Eleventy\u2019s config:\nmodule.exports = function(eleventyConfig) {\n  // Aliases are in relation to the _includes folder\n  eleventyConfig.addLayoutAlias('about', 'layouts/about.html');\n  eleventyConfig.addLayoutAlias('book', 'layouts/book.html');\n  eleventyConfig.addLayoutAlias('default', 'layouts/default.html');\n\n  return {\n    dir: {\n      input: \"./\",\n      output: \"./_site\"\n    }\n  };\n}\nDetermining which template language to use\nEleventy will transform Markdown (.md) files using Liquid by default, but we\u2019ll need to tell Eleventy how to process other files that are using Liquid templates. There are a few ways to achieve this, but the easiest is to use file extensions. In our case, we have some files in our api folder that we want to process with Liquid and output as JSON. By appending the .liquid file extension (i.e. basic-syntax.json becomes basic-syntax.json.liquid), Eleventy will know what to do.\nVariables\nOn the surface, Jekyll and Eleventy appear broadly similar, but as each models its content and data a little differently, some template variables will need updating.\nSite variables\nAlongside build settings, Jekyll let\u2019s you store common values in its configuration file which can be accessed in our templates via the site.* namespace. For example, in our Markdown Guide, we have the following values:\ntitle: \"Markdown Guide\"\nurl: https://www.markdownguide.org\nbaseurl: \"\"\nrepo: http://github.com/mattcone/markdown-guide\ncomments: false\nauthor:\n  name: \"Matt Cone\"\nog_locale: \"en_US\"\nEleventy\u2019s configuration uses JavaScript which is not suited to storing values like this. However, like Jekyll, we can use data files to store common values. If we add our site-wide values to a JSON file inside a folder called _data and name this file site.json, we can keep the site.* namespace and leave our variables unchanged.\n{\n  \"title\": \"Markdown Guide\",\n  \"url\": \"https://www.markdownguide.org\",\n  \"baseurl\": \"\",\n  \"repo\": \"http://github.com/mattcone/markdown-guide\",\n  \"comments\": false,\n  \"author\": {\n    \"name\": \"Matt Cone\"\n  },\n  \"og_locale\": \"en_US\"\n}\nPage variables\nThe table below shows a mapping of common page variables. As a rule, frontmatter properties are accessed directly, whereas derived metadata values (things like URLs, dates etc.) get prefixed with the page.* namespace:\n\n\n\nJekyll\nEleventy\n\n\n\n\npage.url\npage.url\n\n\npage.date\npage.date\n\n\npage.path\npage.inputPath\n\n\npage.id\npage.outputPath\n\n\npage.name\npage.fileSlug\n\n\npage.content\ncontent\n\n\npage.title\ntitle\n\n\npage.foobar\nfoobar\n\n\n\nWhen iterating through pages, frontmatter values are available via the data object while content is available via templateContent:\n\n\n\nJekyll\nEleventy\n\n\n\n\nitem.url\nitem.url\n\n\nitem.date\nitem.date\n\n\nitem.path\nitem.inputPath\n\n\nitem.name\nitem.fileSlug\n\n\nitem.id\nitem.outputPath\n\n\nitem.content\nitem.templateContent\n\n\nitem.title\nitem.data.title\n\n\nitem.foobar\nitem.data.foobar\n\n\n\nIdeally the discrepancy between page and item variables will change in a future version (see this GitHub issue), making it easier to understand the way Eleventy structures its data.\nPagination variables\nWhereas Jekyll\u2019s pagination feature is limited to paginating posts on one page, Eleventy allows you to paginate any collection of documents or data. Given this disparity, the changes to pagination are more significant, but this table shows a mapping of equivalent variables:\n\n\n\nJekyll\nEleventy\n\n\n\n\npaginator.page\npagination.pageNumber\n\n\npaginator.per_page\npagination.size\n\n\npaginator.posts\npagination.items\n\n\npaginator.previous_page_path\npagination.previousPageHref\n\n\npaginator.next_page_path\npagination.nextPageHref\n\n\n\nFilters\nAlthough Jekyll uses Liquid, it provides a set of filters that are not part of the core Liquid library. There are quite a few \u2014 more than can be covered by this article \u2014 but you can replicate them by using Eleventy\u2019s addFilter configuration option. Let\u2019s convert two used by our Markdown Guide: jsonify and where.\nThe jsonify filter outputs an object or string as valid JSON. As JavaScript provides a native JSON method, we can use this in our replacement filter. addFilter takes two arguments; the first is the name of the filter and the second is the function to which we will pass the content we want to transform:\n// {{ variable | jsonify }}\neleventyConfig.addFilter('jsonify', function (variable) {\n  return JSON.stringify(variable);\n});\nJekyll\u2019s where filter is a little more complicated in that it takes two additional arguments: the key to look for, and the value it should match:\n{{ site.members | where: \"graduation_year\",\"2014\" }}\nTo account for this, instead of passing one value to the second argument of addFilter, we can instead pass three: the array we want to examine, the key we want to look for and the value it should match:\n// {{ array | where: key,value }}\neleventyConfig.addFilter('where', function (array, key, value) {\n  return array.filter(item => {\n    const keys = key.split('.');\n    const reducedKey = keys.reduce((object, key) => {\n      return object[key];\n    }, item);\n\n    return (reducedKey === value ? item : false);\n  });\n});\nThere\u2019s quite a bit going on within this filter, but I\u2019ll try to explain. Essentially we\u2019re examining each item in our array, reducing key (passed as a string using dot notation) so that it can be parsed correctly (as an object reference) before comparing its value to value. If it matches, item remains in the returned array, else it\u2019s removed. Phew!\nIncludes\nAs with filters, Jekyll provides a set of tags that aren\u2019t strictly part of Liquid either. This includes one of the most useful, the include tag. LiquidJS, the library Eleventy uses, does provide an  include tag, but one using the slightly different syntax defined by Shopify. If you\u2019re not passing variables to your includes, everything should work without modification. Otherwise, note that whereas with Jekyll you would do this:\n<!-- page.html -->\n{% include include.html value=\"key\" %}\n\n<!-- include.html -->\n{{ include.value }}\nin Eleventy, you would do this:\n<!-- page.html -->\n{% include \"include.html\", value: \"key\" %}\n\n<!-- include.html -->\n{{ value }}\nA downside of Shopify\u2019s syntax is that variable assignments are no longer scoped to the include and can therefore leak; keep this in mind when converting your templates as you may need to make further adjustments.\nTweaking Liquid\nYou may have noticed in the above example that LiquidJS expects the names of included files to be quoted (else it treats them as variables). We could update our templates to add quotes around file names (the recommended approach), but we could also disable this behaviour by setting LiquidJS\u2019s dynamicPartials option to false. Additionally, Eleventy doesn\u2019t support the include_relative tag, meaning you can\u2019t include files relative to the current document. However, LiquidJS does let us define multiple paths to look for included files via its root option. \nThankfully, Eleventy allows us to pass options to LiquidJS:\neleventyConfig.setLiquidOptions({\n  dynamicPartials: false,\n  root: [\n    '_includes',\n    '.'\n  ]\n});\nCollections\nJekyll\u2019s collections feature lets authors create arbitrary collections of documents beyond pages and posts. Eleventy provides a similar feature, but in a far more powerful way.\nCollections in Jekyll\nIn Jekyll, creating collections requires you to add the name of your collections to _config.yml and create corresponding folders in your project. Our Markdown Guide has two collections:\ncollections:\n  - basic-syntax\n  - extended-syntax\nThese correspond to the folders _basic-syntax and _extended-syntax whose content we can iterate over like so:\n{% for syntax in site.extended-syntax %}\n  {{ syntax.title }}\n{% endfor %}\nCollections in Eleventy\nThere are two ways you can set up collections in 11ty. The first, and most straightforward, is to use the tag property in content files:\n---\ntitle: Strikethrough\nsyntax-id: strikethrough\nsyntax-summary: \"~~The world is flat.~~\"\ntag: extended-syntax\n---\nWe can then iterate over tagged content like this:\n{% for syntax in collections.extended-syntax %}\n  {{ syntax.data.title }}\n{% endfor %}\nEleventy also allows us to configure collections programmatically. For example, instead of using tags, we can search for files using a glob pattern (a way of specifying a set of filenames to search for using wildcard characters):\neleventyConfig.addCollection('basic-syntax', collection => {\n  return collection.getFilteredByGlob('_basic-syntax/*.md');\n});\n\neleventyConfig.addCollection('extended-syntax', collection => {\n  return collection.getFilteredByGlob('_extended-syntax/*.md');\n});\nWe can extend this further. For example, say we wanted to sort a collection by the display_order property in our document\u2019s frontmatter. We could take the results of collection.getFilteredByGlob and then use JavaScript\u2019s sort method to sort the result:\neleventyConfig.addCollection('example', collection => {\n  return collection.getFilteredByGlob('_examples/*.md').sort((a, b) => {\n    return a.data.display_order - b.data.display_order;\n  });\n});\nHopefully, this gives you just a hint of what\u2019s possible using this approach.\nUsing directory data to manage defaults\nBy default, Eleventy will maintain the structure of your content files when generating your site. In our case, that means /_basic-syntax/lists.md is generated as /_basic-syntax/lists/index.html. Like Jekyll, we can change where files are saved using the permalink property. For example, if we want the URL for this page to be /basic-syntax/lists.html we can add the following:\n---\ntitle: Lists\nsyntax-id: lists\napi: \"no\"\npermalink: /basic-syntax/lists.html\n---\nAgain, this is probably not something we want to manage on a file-by-file basis but again, Eleventy has features that can help: directory data and permalink variables.\nFor example, to achieve the above for all content stored in the _basic-syntax folder, we can create a JSON file that shares the name of that folder and sits inside it, i.e. _basic-syntax/_basic-syntax.json and set our default values. For permalinks, we can use Liquid templating to construct our desired path:\n{\n  \"layout\": \"syntax\",\n  \"tag\": \"basic-syntax\",\n  \"permalink\": \"basic-syntax/{{ title | slug }}.html\"\n}\nHowever, Markdown Guide doesn\u2019t publish syntax examples at individual permanent URLs, it merely uses content files to store data. So let\u2019s change things around a little. No longer tied to Jekyll\u2019s rules about where collection folders should be saved and how they should be labelled, we\u2019ll move them into a folder called _content:\nmarkdown-guide\n\u2514\u2500\u2500 _content\n    \u251c\u2500\u2500 basic-syntax\n    \u251c\u2500\u2500 extended-syntax\n    \u251c\u2500\u2500 getting-started\n    \u2514\u2500\u2500 _content.json\nWe will also add a directory data file (_content.json) inside this folder. As directory data is applied recursively, setting permalink to false will mean all content in this folder and its children will no longer be published:\n{\n  \"permalink\": false\n}\nStatic files\nEleventy only transforms files whose template language it\u2019s familiar with. But often we may have static assets that don\u2019t need converting, but do need copying to the destination directory. For this, we can use pass-through file copy. In our configuration file, we tell Eleventy what folders/files to copy with the addPassthroughCopy option. Then in the return statement, we enable this feature by setting passthroughFileCopy to true:\nmodule.exports = function(eleventyConfig) {\n  \u2026\n\n  // Copy the `assets` directory to the compiled site folder\n  eleventyConfig.addPassthroughCopy('assets');\n\n  return {\n    dir: {\n      input: \"./\",\n      output: \"./_site\"\n    },\n    passthroughFileCopy: true\n  };\n}\nFinal considerations\nAssets\nUnlike Jekyll, Eleventy provides no support for asset compilation or bundling scripts \u2014 we have plenty of choices in that department already. If you\u2019ve been using Jekyll to compile Sass files into CSS, or CoffeeScript into Javascript, you will need to research alternative options, options which are beyond the scope of this article, sadly.\nPublishing to GitHub Pages\nOne of the benefits of Jekyll is its deep integration with GitHub Pages. To publish an Eleventy generated site \u2014 or any site not built with Jekyll \u2014 to GitHub Pages can be quite involved, but typically involves copying the generated site to the gh-pages branch or including that branch as a submodule. Alternatively, you could use a continuous integration service like Travis or CircleCI and push the generated site to your web server. It\u2019s enough to make your head spin! Perhaps for this reason, a number of specialised static site hosts have emerged such as Netlify and Google Firebase. But remember; you can publish a static site almost anywhere!\n\nGoing one louder\nIf you\u2019ve been considering making the switch, I hope this brief overview has been helpful. But it also serves as a reminder why it can be prudent to avoid jumping aboard bandwagons. \nWhile it\u2019s fun to try new software and emerging technologies, doing so can require a lot of work and compromise. For all of Eleventy\u2019s appeal, it\u2019s only a year old so has little in the way of an ecosystem of plugins or themes. It also only has one maintainer. Jekyll on the other hand is a mature project with a large community of maintainers and contributors supporting it.\nI moved my site to Eleventy because the slowness and inflexibility of Jekyll was preventing me from doing the things I wanted to do. But I also had time to invest in the transition. After reading this guide, and considering the specific requirements of your project, you may decide to stick with Jekyll, especially if the output will essentially stay the same. And that\u2019s perfectly fine! \nBut these go to 11.\n\n\n\n\nInformation provided is correct as of Eleventy v0.6.0 and Jekyll v3.8.5\u00a0\u21a9", "year": "2018", "author": "Paul Lloyd", "author_slug": "paulrobertlloyd", "published": "2018-12-11T00:00:00+00:00", "url": "https://24ways.org/2018/turn-jekyll-up-to-eleventy/", "topic": "content"}
{"rowid": 268, "title": "Getting the Most Out of Google Analytics", "contents": "Something a bit different for today\u2019s 24 ways article. For starters, I\u2019m not a designer or a developer. I\u2019m an evil man who sells things to people on the internet. Second, this article will likely be a little more nebulous than you\u2019re used to, since it covers quite a number of points in a relatively short space. \n\nThis isn\u2019t going to be the complete Google Analytics Conversion University IQ course compressed into a single article, obviously. What it will be, however, is a primer on setting up and using Google Analytics in real life, and a great deal of what I\u2019ve learned using Google Analytics nearly every working day for the past six (crikey!) years.\n\nAlso, to be clear, I\u2019ll be referencing new Google Analytics here; old Google Analytics is for loooosers (and those who want reliable e-commerce conversion data per site search term, natch).\n\nYou may have been running your Analytics account for several years now, dipping in and out, checking traffic levels, seeing what\u2019s popular\u2026 and that\u2019s about it. Google Analytics provides so much more than that, but the number of reports available can often intimidate users, and documentation and case studies on their use are minimal at best. \n\nLet\u2019s start! Setting up your Analytics profile\n\nBefore we plough on, I just want to run through a quick checklist that some basic settings have been enabled for your profile. If you haven\u2019t clicked it, click the big cog on the top-right of Google Analytics and we\u2019ll have a poke about.\n\n\n\tIf you have an e-commerce site, e-commerce tracking has been enabled\u2028\n\tIf your site has a search function, site search tracking has been enabled.\n\tQuery string parameters that you do not want tracked as separate pages have been excluded (for example, any parameters needed for your platform to function, otherwise you\u2019ll get multiple entries for the same page appearing in your reports)\n\tFilters have been enabled on your main profile to exclude your office IP address and any IPs of people who frequently access the site for work purposes. In decent numbers they tend to throw data off a tad.\u2028\n\tYou may also find the need to set up multiple profiles prefiltered for specific audience segments. For example, at Lovehoney we have seventeen separate profiles that allow me quick access to certain countries, devices and traffic sources without having to segment first. You\u2019ll also find load time for any complex reports much improved. Use the same filter screen as above to set up a series of profiles that only include, say, mobile visits, or UK visitors, so you can quickly analyse important segments.\n\n\nMatt, what\u2019s a segment?\n\nA segment is a subsection of your visitor base, which you define and then call on in reports to see specific data for that subsection. For example, in this report I\u2019ve defined two segments, the first for IE6 users and the second for IE7.\n\n\n\nSegments are easily created by clicking the Advanced Segments tabs at the top of any report and clicking +New Custom Segment.\n\n\n\nWhat does your site do?\n\nUnderstanding the goals of your site is an oft-covered topic, but it\u2019s necessary not just to form a better understand of your business and prioritize your time. Understanding what you wish visitors to do on your site translates well into a goal-driven analytics package like Google Analytics.  \n\nEvery site exists essentially to sell something, either financially through e-commerce, or to sell an idea or impart information, get people to download a CV or enquire about service, or to sell space on that website to advertisers. If the site did not provide a positive benefit to its owners, it would not have a reason for being. \n\nOnce you have understood the reason why you have a site, you can map that reason on to one of the three goal types Google Analytics provides. \n\nE-commerce \n\nThis conversion type registers transactions as part of a sales process which requires a monetary value, what products have been bought, an SKU (stock keeping unit), affiliation (if you\u2019re then attributing the sale to a third party or franchise) and so on.\n\nThe benefit of e-commerce tracking is not only assigning non-arbitrary monetary value to behaviour of visitors on your site, as well as being able to see ancillary costs such as shipping, but seeing product-level information, like which products are preferred from various channels, popular categories, and so on.\n\n\n\nHowever, I find the e-commerce tracking options also useful for non-e-commerce sites. For example, if you\u2019re offering downloads or subscriptions and having an email address or user\u2019s details is worth something to you, you can set up e-commerce tracking to understand how much value your site is bringing. For example, an email address might be worth 20p to you, but if it also includes a name it\u2019s worth 50p. A contact telephone number is worth \u00a32, and so on.\n\nPage goals\n\nPage goals, unsurprisingly, track a visit to a page (often with a sequence of pages leading up to that page). This is what\u2019s referred to as a goal funnel, and is generally used to track how visitors behave in a multistep checkout. \n\n\n\nInterestingly, the page doesn\u2019t have to actually exist. For example, if you have a single page checkout, you can register virtual page views using trackPageview() when a visitor clicks into a particular section of the checkout or other form. If your site is geared towards getting someone to a particular page, but where there isn\u2019t a transaction (for example, a subscription page) this is for you.\n\nThere are also behavioural goals, such as time on site and number of pages viewed, which are geared towards sites that make money from advertising.\n\nBut, going back to the page goals, these can be abstracted using regular expressions, meaning that you can define a funnel based on page type rather than having to set individual folders.\n\n\n\nIn this example, I\u2019ve created regexes for the main page types on my site, so I can create a wide funnel that captures visitors from where they enter through to checkout.\n\nEvents\n\nEvent tracking registers a predefined event, such as playing a video, or some interaction that can trigger JavaScript, such as a Tweet This button. Events can then be triggered using the trackEvent() call. If you want someone to complete watching a video, you would code your player to fire trackEvent() upon completion. \n\nWhile I don\u2019t use events as goals, I use events elsewhere to see how well a video play aids to conversion. This not only helps me justify the additional spend on creating video content, but also quickly highlights which videos are underperforming as sales tools.\n\n\n\nWhat a visitor can tell you\n\n\u2028Now you have some proper goals set up, we can start to see how changes in content (on-site and external) affect those goals. \n\nUltimately, when a visitor comes to your site, they bring information with them:\n\n\n\twhere they came from (a search engine \u2013 including: keyword searched for; a referral; direct; affiliate; or ad campaign)\n\tdemographics (country; whether they\u2019re new or returning, within thirty days)\n\ttechnical information (browser; screen size; device; bandwidth)\n\tsite-specific information (landing page; next click; previous values assigned to them as custom variables*)\n\n\n * A note about custom variables. There\u2019s no hope in hell that I can cover custom variables in this article. Go research them. Custom variables are the single best way to hack Google Analytics and bend it to your will. Custom variables allow you to record anything you want about a visitor, which that visitor will then carry around with them between visits. It\u2019s also great for plugging other services into Google Analytics (as shown by the marvelous way Visual Website Optimizer allows you to track and segment tests within the GA interface). Just make sure not to breach the terms of service, eh?\n\nCSI your website\n\nPolice procedural TV shows are all the same: the investigators are called to a crime and come across a clue; there\u2019s then an autopsy; new evidence leads them to a new location; they find a new clue; they put two and two together; they solve the mystery.\n\nThis is your life now. Exciting!\n\nSo, now you\u2019re gathering a wealth of information about what sort of people visit your site, what they do when they\u2019re there, and what eventually gets them to drive value to you. It\u2019s now your job to investigate all these little clues to see which types of people drive the most value, and what you can change to improve it.\n\nMaybe not that exciting.\n\nHowever, Google Analytics comes pre-armed with extensive reports for you to delve into. As an e-commerce guy (as opposed to a page goal guy) my day pretty much follows the pattern below.\n\n\n\tLook at e-commerce conversion rate by traffic source compared to the same day in the previous week and previous month. As ours is an e-commerce site, we have weekly and monthly trends. A big spike on Sundays and Mondays, and payday towards the end of the month is always good; on the third week of a month there tends to be a lull. Spend time letting your Google Analytics data brew, understand your own trends and patterns, and you\u2019ll start to get a feel for when something isn\u2019t quite right.\n\t\n\t\tTraffic Sources \u2192 Sources \u2192 All Traffic\n\t\n\tLook at the conversion rate by landing page for any traffic source that feels significantly different to what\u2019s expected. Check bounce rates, drill down to likely landing pages and check search keyword or referral site to see if it\u2019s a particular subset of visitor. You can do this by clicking Secondary Dimension and choosing Keyword or Source. If it\u2019s direct, choose Visitor Type to break down by new or returning visitor.\n\t\n\t\tContent \u2192 Site Content \u2192 Landing Pages\n\t\n\tI then tend to flip into Content Drilldown to see what the next clicks were from those landing pages, and whether they changed significantly to the date I\u2019m comparing with. If they have, that\u2019s usually an indicator of changed content (or its relevancy). Remember, if a bunch of people have found their way to your page via a method you\u2019re not expecting (such as a mention on a Spanish radio station \u2013 this actually happened to me once), while the content hasn\u2019t changed, the relevancy of it to the audience may have.\n\t\n\t\tContent \u2192 Site Content \u2192 Content Drilldown\n\t\n\tOnce I have an idea of what content was consumed, and whether it was relevant to the user, I then look at the visitor specifics, such as browser or demographic data, to see again whether the change was limited to a specific subset. Site speed, for example, is normally a good factor towards bounce rate, so compare that with previous data as well.\n\n\nNow, to be investigating at this level you still need a serious amount of data, in order to tell what\u2019s a significant change or not. If you\u2019re struggling with a small number of visitors, you might find reporting on a weekly or fortnightly basis more appropriate. \n\nHowever, once you\u2019ve looked into the basics of why changes happen to the value of your site, you\u2019ll soon find yourself limited by the reports offered in Standard Reporting. So, it\u2019s time to build your own. Hooray!\n\nCustom reporting\n\nGoogle Analytics provides the tools to build reports specific to the types of investigations you frequently perform. \n\n\n\nWelcome to my world.\n\nCustom reports are quite simple to build: first, you determine the metric you want the report to cover (number of visitors, bounce rate, conversion rate, and so on), then choose a set of dimensions that you\u2019d like to segment the report by (say, the source of the traffic, and whether they were new or returning users). You can filter the report, including or excluding particular dimension values, and you can assign the report to any of the profiles you created earlier. \n\nIn the example below, I\u2019ve created a report that shows me visits and conversion rate for any Google traffic that landed directly only on a product page. I can then drill down on each product page to see the complete phrases use to search. I can use this information in two ways:\n\n\n\tI can see which products aren\u2019t converting, which shows me where I need to work harder on merchandising.\n\tI can give this information to my content team, showing them the actual phrases visitors used to reach our product content, helping them write better targeted product descriptions.\n\n\n\n\nThe possibilities here are nearly endless, but here are a few examples of reports I find useful:\n\n\n\tNon-brand inbound search\nBy creating a report that shows inbound search traffic which doesn\u2019t include your brand, you can see more clearly the behaviour of visitors most likely to be unfamiliar with your site and brand values, without having to rely on the clumsy new or returning demographic date.\n\tTraffic/conversion/sales by hour\nThis is pure stats porn, but actually more useful than real-time data. By seeing this data broken down at an hourly level, you can not only compare the current day to previous days, but also see the best performing times for email broadcasts and tweets.\n\tVisits, load time, conversion and sales by page and browser\nPage speed can often kill conversion rates, but it\u2019s difficult to prove the value of focusing on speed in monetary terms. Having this report to hand helps me drive Operation Greenbelt, our effort to get into the sub-1.5 second band in Google Webmaster Tools.\n\n\nUseful things you can\u2019t do in custom reporting\n\nIf you have a search function on your website, then Conversion Rate and Products Bought by Site Search Term is an incredibly useful report that allows you to measure the effectiveness of your site\u2019s search engine at returning products and content related to the search term used. By including the products actually bought by visitors who searched for each term, you can use this information to better searchandise these results, escalating high propensity and high value products to the top of the results.\n\nHowever, it\u2019s not possible to get this information out of new Google Analytics. \n\nTry it, select the following in the report builder:\n\n\n\tMetrics: total unique searches; e-commerce or goal conversion rate\n\tDimensions: search term; product\n\n\nYou\u2019ll see that the data returned is a little nonsensical, though a 2,000% conversion rate would be nice. However, you can get more accurate information using advanced segments. By creating individual segments to define users who have searched for a particular term, you can run the sales performance and product performance reports as normal. It\u2019s laborious, but it teaches a good lesson: data that seems inaccessible can normally be found another way!\n\nReporting infrastructure\n\nNow that you have a series of reports that you can refer to on a daily or weekly basis, it\u2019s time to put together a regular reporting infrastructure. \n\nEven if you\u2019re not reporting to someone, having a set of key performance indicators that you can use to see how your performance is improving over time allows you to set yourself business goals on a monthly and annual basis.\n\nFor my own reporting, I take some high-level metrics (such as visitors, conversion rate and average order value), and segment them by traffic source and, separately, landing page. These statistics I record weekly and report:\n\n\n\tcurrent week compared with previous week\n\tsame week previous year (if available)\n\t4 week average\n\t13 week average\n\t52 week average (if available)\n\n\nThis takes into account weekly, monthly, seasonal and annual trends, and gives you a much clearer view of your performance.\n\nGetting data in other ways\n\nIf you\u2019re using Google Analytics frequently, with any large site you\u2019ll come to a couple of conclusions:\n\n\n\tDoing any kind of practical comparative analysis is unwieldy.\n\tBoy, Google Analytics is slow!\n\n\nAs you work with bigger datasets and put together more complex queries, you\u2019ll see the loading graphic more than you\u2019ll see actual data. So when you reach that level, there are ways to completely bypass the Google Analytics interface altogether, and get data into your own spreadsheet application for manipulation.\n\nData Feed Query Explorer\n\nIf you just want to pull down some quick statistics but still use complex filters and exotic metric and dimension combinations, the Data Feed Query Explorer is the quickest way of doing so. Authenticate with your Google Analytics account, select a profile, and you can start selecting metrics and dimensions to be generated in a handy, selectable tabulated format.\n\nGoogle Analytics API\n\nIf you\u2019re feeling clever, you can bypass having to copy and paste data by pulling in directly into Excel, Google Docs or your own application using the Google Analytics API. There are several scripts and plugins available to do this. I use Automate Analytics Google Docs code (there\u2019s also a paid version that simplifies setup and creates some handy reports for you).\n\nNew shiny things\n\nWell, now that that\u2019s over, I can show you some cool stuff. Well, at least it\u2019s cool to me. Google Analytics is being constantly improved and new functionality is introduced nearly every month. Here are a couple of my favourites.\n\nMultichannel attribution\n\nNot every visitor converts on your site on the first visit. They may not even do so on the second visit, or third. If they convert on the fourth visit, but each time they visit they do so via a different channel (for example, Search PPC, Search Organic, Direct, Email), which channel do you attribute the conversion to? The last channel, or the first? Dilemma!  \n\nGoogle now has a Multichannel Attribution report, available in the Conversion category, which shows how each channel assists in converting, the overlap between channels, and where in the process that channel was important. \n\n\n\nFor example, you may have analysed your blog traffic from Twitter and become disheartened that not many people were subscribing after visiting from Twitter links, but instead your high-value subscribers were coming from natural search. On the face of it, you\u2019d spend less time tweeting, but a multichannel report may tell you that visitors first arrived via a Twitter link and didn\u2019t subscribe, but then came back later after searching for your blog name on Google, after which they did. Don\u2019t pack Twitter in yet!\n\nVisitor and goal flow\n\nVisitor and goal flow are amazing reports that help you visualize the flow of traffic through your site and, ultimately, into your checkout funnel or similar goal path. Flow reports are perfect for understanding drop-off points in your process, as well as what the big draws are on each page. \n\n\n\nPreviously, if you wanted to visualize this data you had to set up several abstracted microgoals and chain them together in custom reports. Frankly, it was a pain in the arse and burned through your precious and limited goal allocation.\n\nVisitor flow bypasses all that and produces the report in an interactive flow diagram. While it doesn\u2019t show you the holy grail of conversion likelihood by each path, you can segment visitor flow so that you can see very specifically how different segments of your visitor base behave.\n\nGo play with it now!", "year": "2011", "author": "Matt Curry", "author_slug": "mattcurry", "published": "2011-12-18T00:00:00+00:00", "url": "https://24ways.org/2011/getting-the-most-out-of-google-analytics/", "topic": "business"}
{"rowid": 223, "title": "Calculating Color Contrast", "contents": "Some websites and services allow you to customize your profile by uploading pictures, changing the background color or other aspects of the design. As a customer, this personalization turns a web app into your little nest where you store your data. As a designer, letting your customers have free rein over the layout and design is a scary prospect. So what happens to all the stock text and images that are designed to work on nice white backgrounds? Even the Mac only lets you choose between two colors for the OS, blue or graphite! Opening up the ability to customize your site\u2019s color scheme can be a recipe for disaster unless you are flexible and understand how to find maximum color contrasts.\n\nIn this article I will walk you through two simple equations to determine if you should be using white or black text depending on the color of the background. The equations are both easy to implement and produce similar results. It isn\u2019t a matter of which is better, but more the fact that you are using one at all! That way, even with the craziest of Geocities color schemes that your customers choose, at least your text will still be readable.\n\nLet\u2019s have a look at a range of various possible colors. Maybe these are pre-made color schemes, corporate colors, or plucked from an image.\n\n\n\nNow that we have these potential background colors and their hex values, we need to find out whether the corresponding text should be in white or black, based on which has a higher contrast, therefore affording the best readability. This can be done at runtime with JavaScript or in the back-end before the HTML is served up.\n\nThere are two functions I want to compare. The first, I call \u201950%\u2019. It takes the hex value and compares it to the value halfway between pure black and pure white. If the hex value is less than half, meaning it is on the darker side of the spectrum, it returns white as the text color. If the result is greater than half, it\u2019s on the lighter side of the spectrum and returns black as the text value.\n\nIn PHP:\n\nfunction getContrast50($hexcolor){\n    return (hexdec($hexcolor) > 0xffffff/2) ? 'black':'white';\n}\n\nIn JavaScript:\n\nfunction getContrast50(hexcolor){\n    return (parseInt(hexcolor, 16) > 0xffffff/2) ? 'black':'white';\n}\n\nIt doesn\u2019t get much simpler than that! The function converts the six-character hex color into an integer and compares that to one half the integer value of pure white. The function is easy to remember, but is naive when it comes to understanding how we perceive parts of the spectrum. Different wavelengths have greater or lesser impact on the contrast.\n\nThe second equation is called \u2018YIQ\u2019 because it converts the RGB color space into YIQ, which takes into account the different impacts of its constituent parts. Again, the equation returns white or black and it\u2019s also very easy to implement.\n\nIn PHP:\n\nfunction getContrastYIQ($hexcolor){\n\t$r = hexdec(substr($hexcolor,0,2));\n\t$g = hexdec(substr($hexcolor,2,2));\n\t$b = hexdec(substr($hexcolor,4,2));\n\t$yiq = (($r*299)+($g*587)+($b*114))/1000;\n\treturn ($yiq >= 128) ? 'black' : 'white';\n}\n\nIn JavaScript:\n\nfunction getContrastYIQ(hexcolor){\n\tvar r = parseInt(hexcolor.substr(0,2),16);\n\tvar g = parseInt(hexcolor.substr(2,2),16);\n\tvar b = parseInt(hexcolor.substr(4,2),16);\n\tvar yiq = ((r*299)+(g*587)+(b*114))/1000;\n\treturn (yiq >= 128) ? 'black' : 'white';\n}\n\nYou\u2019ll notice first that we have broken down the hex value into separate RGB values. This is important because each of these channels is scaled in accordance to its visual impact. Once everything is scaled and normalized, it will be in a range between zero and 255. Much like the previous \u201950%\u2019 function, we now need to check if the input is above or below halfway. Depending on where that value is, we\u2019ll return the corresponding highest contrasting color.\n\nThat\u2019s it: two simple contrast equations which work really well to determine the best readability.\n\nIf you are interested in learning more, the W3C has a few documents about color contrast and how to determine if there is enough contrast between any two colors. This is important for accessibility to make sure there is enough contrast between your text and link colors and the background.\n\nThere is also a great article by Kevin Hale on Particletree about his experience with choosing light or dark themes. To round it out, Jonathan Snook created a color contrast picker which allows you to play with RGB sliders to get values for YIQ, contrast and others. That way you can quickly fiddle with the knobs to find the right balance.\n\nComparing results\n\nLet\u2019s revisit our color schemes and see which text color is recommended for maximum contrast based on these two equations.\n\n\n\nIf we use the simple \u201950%\u2019 contrast function, we can see that it recommends black against all the colors except the dark green and purple on the second row. In general, the equation feels the colors are light and that black is a better choice for the text.\n\n\n\nThe more complex \u2018YIQ\u2019 function, with its weighted colors, has slightly different suggestions. White text is still recommended for the very dark colors, but there are some surprises. The red and pink values show white text rather than black. This equation takes into account the weight of the red value and determines that the hue is dark enough for white text to show the most contrast.\n\nAs you can see, the two contrast algorithms agree most of the time. There are some instances where they conflict, but overall you can use the equation that you prefer. I don\u2019t think it is a major issue if some edge-case colors get one contrast over another, they are still very readable.\n\nNow let\u2019s look at some common colors and then see how the two functions compare. You can quickly see that they do pretty well across the whole spectrum.\n\n\n\nIn the first few shades of grey, the white and black contrasts make sense, but as we test other colors in the spectrum, we do get some unexpected deviation. Pure red #FF0000 has a flip-flop. This is due to how the \u2018YIQ\u2019 function weights the RGB parts. While you might have a personal preference for one style over another, both are justifiable.\n\n\n\nIn this second round of colors, we go deeper into the spectrum, off the beaten track. Again, most of the time the contrasting algorithms are in sync, but every once in a while they disagree. You can select which you prefer, neither of which is unreadable.\n\nConclusion\n\nContrast in color is important, especially if you cede all control and take a hands-off approach to the design. It is important to select smart defaults by making the contrast between colors as high as possible. This makes it easier for your customers to read, increases accessibility and is generally just easier on the eyes. \n\nSure, there are plenty of other equations out there to determine contrast; what is most important is that you pick one and implement it into your system.\n\nSo, go ahead and experiment with color in your design. You now know how easy it is to guarantee that your text will be the most readable in any circumstance.", "year": "2010", "author": "Brian Suda", "author_slug": "briansuda", "published": "2010-12-24T00:00:00+00:00", "url": "https://24ways.org/2010/calculating-color-contrast/", "topic": "code"}
{"rowid": 218, "title": "Put Yourself in a Corner", "contents": "Some backstory, and a shameful confession\n\nFor the first couple years of high school I was one of those jerks who made only the minimal required effort in school. Strangely enough, how badly I behaved in a class was always in direct proportion to how skilled I was in the subject matter. In the subjects where I was confident that I could pass without trying too hard, I would give myself added freedom to goof off in class.\n\nBecause I was a closeted lit-nerd, I was most skilled in English class. I\u2019d devour and annotate required reading over the weekend, I knew my biblical and mythological allusions up and down, and I could give you a postmodern interpretation of a text like nobody\u2019s business. But in class, I\u2019d sit in the back and gossip with my friends, nap, or scribble patterns in the margins of my textbooks. I was nonchalant during discussion, I pretended not to listen during lectures. I secretly knew my stuff, so I did well enough on tests, quizzes, and essays. But I acted like an ass, and wasn\u2019t getting the most I could out of my education.\n\nThe day of humiliation, but also epiphany\n\nOne day in Ms. Kaney\u2019s AP English Lit class, I was sitting in the back doodling. An earbud was dangling under my sweater hood, attached to the CD player (remember those?) sitting in my desk. Because of this auditory distraction, the first time Ms. Kaney called my name, I barely noticed. I definitely heard her the second time, when she didn\u2019t call my name so much as roar it. I can still remember her five feet frame stomping across the room and grabbing an empty desk. It screamed across the worn tile as she slammed it next to hers. She said, \u201cThis is where you sit now.\u201d My face gets hot just thinking about it.\n\nI gathered my things, including the CD player (which was now impossible to conceal), and made my way up to the newly appointed Seat of Shame. There I sat, with my back to the class, eye-to-eye with Ms. Kaney. From my new vantage point I couldn\u2019t see my friends, or the clock, or the window. All I saw were Ms. Kaney\u2019s eyes, peering at me over her reading glasses while I worked. In addition to this punishment, I was told that from now on, not only would I participate in class discussions, but I would serve detention with her once a week until an undetermined point in the future.\n\nDuring these detentions, Ms. Kaney would give me new books to read, outside the curriculum, and added on to my normal homework. They ranged from classics to modern novels, and she read over my notes on each book. We\u2019d discuss them at length after class, and I grew to value not only our private discussions, but the ones in class as well. After a few weeks, there wasn\u2019t even a question of this being punishment. It was heaven, and I was more productive than ever.\n\nTo the point\n\nPlease excuse this sentimental story. It\u2019s not just about honoring a teacher who cared enough to change my life, it\u2019s really about sharing a lesson. The most valuable education Ms. Kaney gave me had nothing to do with literature. She taught me that I (and perhaps other people who share my special brand of crazy) need to be put in a corner to flourish. When we have physical and mental constraints applied, we  accomplish our best work.\n\nFor those of you still reading, now seems like a good time to insert a pre-emptive word of mediation. Many of you, maybe all of you, are self-disciplined enough that you don\u2019t require the rigorous restrictions I use to maximize productivity. Also, I know many people who operate best in a stimulating and open environment. I would advise everyone to seek and execute techniques that work best for them. But, for those of you who share my inclination towards daydreams and digressions, perhaps you\u2019ll find something useful in the advice to follow.\n\nIn which I pretend to be Special Agent Olivia Dunham\n\nNow that I\u2019m an adult, and no longer have Ms. Kaney to reign me in, I have to find ways to put myself in the corner. By rejecting distraction and shaping an environment designed for intense focus, I\u2019m able to achieve improved productivity.\n\nLately I\u2019ve been obsessed with the TV show Fringe, a sci-fi series about an FBI agent and her team of genius scientists who save the world (no, YOU\u2019RE a nerd). There\u2019s a scene in the show where the primary character has to delve into her subconscious to do extraordinary things, and she accomplishes this by immersing herself in a sensory deprivation tank. The premise is this: when enclosed in a space devoid of sound, smell, or light, she will enter a new plane of consciousness wherein she can tap into new levels of perception.\n\nThis might sound a little nuts, but to me this premise has some real-world application. When I am isolated from distraction, and limited to only the task at hand, I\u2019m able to be productive on a whole new level. Since I can\u2019t actually work in an airtight iron enclosure devoid of input, I find practical ways to create an interruption-free environment.\n\nSince I work from home, many of my methods for coping with distractions wouldn\u2019t be necessary for my office-bound counterpart. However for some of you 9-to-5-ers, the principles will still apply.\n\nConsider your visual input\n\nFirst, I have to limit my scope to the world I can (and need to) affect. In the largest sense, this means closing my curtains to the chaotic scene of traffic, birds, the post office, a convenience store, and generally lovely weather that waits outside my window. When the curtains are drawn and I\u2019m no longer surrounded by this view, my sphere is reduced to my desk, my TV, and my cat. Sometimes this step alone is enough to allow me to focus. \n\nBut, my visual input can be whittled down further still. For example, the desk where I usually keep my laptop is littered with twelve owl figurines, a globe, four books, a three-pound weight, and various nerdy paraphernalia (hard drives, Wacom tablets, unnecessary bluetooth accessories, and so on). It\u2019s not so much a desk as a dumping ground for wacky flea market finds and impulse technology buys. Therefore, in addition to this Official Desk, I have an adult version of Ms. Kaney\u2019s Seat of Shame. It\u2019s a rusty old student\u2019s desk I picked up at the Salvation Army, almost an exact replica of the model Ms. Kaney dragged across the classroom all those years ago.  This tiny reproduction Seat of Shame is literally in a corner, where my only view is a blank wall. When I truly need to focus, this is where I take refuge, with only a notebook and a pencil (and occasionally an iPad).\n\nFind out what works for your ears\n\nEven from my limited sample size of two people, I know there are lots of different ways to cope with auditory distraction. I prefer silence when focused on independent work, and usually employ some form of a white noise generator. I\u2019ve yet to opt for the fancy \u2018real\u2019 white noise machines; instead, I use a desktop fan or our allergy filter machine. This is usually sufficient to block out the sounds of the dishwasher and the cat, which allows me to think only about the task of hand.\n\nMy boyfriend, the other half of my extensive survey, swears by another method. He  calls it The Wall of Sound, and it\u2019s basically an intense blast of raucous music streamed directly into his head. The outcome of his technique is really the same as mine; he\u2019s blocking out unexpected auditory input. If you can handle the grating sounds of noisy music while working, I suggest you give The Wall of Sound a try.\n\nDon\u2019t count the minutes\n\nWhen I sat in the original Seat of Shame in lit class, I could no longer see the big classroom clock slowly ticking away the seconds until lunch. Without the marker of time, the class period often flew by. The same is true now when I work; the less aware of time I am, the less it feels like time is passing too quickly or slowly, and the more I can focus on the task (not how long it takes). \n\nNowadays, to assist in my effort to forget the passing of time, I sometimes put a sticky note over the clock on my monitor. If I\u2019m writing, I\u2019ll use an app like WriteRoom, which blocks out everything but a simple text editor. \n\nThere are situations when it\u2019s not advisable to completely lose track of time. If I\u2019m working on a project with an hourly rate and a tight scope, or if I need to be on time to a meeting or call, I don\u2019t want to lose myself in the expanse of the day. In these cases, I\u2019ll set an alarm that lets me know it\u2019s time to reign myself back in (or on some days, take a shower).\n\nPut yourself in a mental corner, too\n\nWhen Ms. Kaney took action and forced me to step up my game, she had the insight to not just change things physically, but to challenge me mentally as well. She assigned me reading material outside the normal coursework, then upped the pressure by requiring detailed reports of the material. While this additional stress was sometimes uncomfortable, it pushed me to work harder than I would have had there been less of a demand. Just as there can be freedom in the limitations of a distraction-free environment, I\u2019d argue there is liberty in added mental constraints as well.\n\nDeadlines as a constraint\n\nMuch has been written about the role of deadlines in the creative process, and they seem to serve different functions in different cases. I find that deadlines usually act as an important constraint and, without them, it would be nearly impossible for me to ever consider a project finished. There are usually limitless ways to improve upon the work I do and, if there\u2019s no imperative for me to be done at a certain point, I will revise ad infinitum. (Hence, the personal site redesign that will never end \u2013 Coming Soon, Forever!). But if I have a clear deadline in mind, there\u2019s a point when the obsessive tweaking has to stop. I reach a stage where I have to gather up the nerve to launch the thing.\n\nPutting the pro in procrastination\n\nSometimes I\u2019ve found that my tendency to procrastinate can help my productivity. (Ducks, as half the internet throws things at her.) I understand the reasons why procrastination can be harmful, and why it\u2019s usually a good idea to work diligently and evenly towards a goal. I try to divide my projects up in a practical way, and sometimes I even pull it off. But for those tasks where you work aimlessly and no focus comes, or you find that every other to-do item is more appealing, sometimes you\u2019re forced to bring it together at the last moment. And sometimes, this environment of stress is a formula for magic. Often when I\u2019m down to the wire and have no choice but to produce, my mind shifts towards a new level of clarity. There\u2019s no time to endlessly browse for inspiration, or experiment with convoluted solutions that lead nowhere.\n\nObviously a life lived perpetually on the edge of a deadline would be a rather stressful one, so it\u2019s not a state of being I\u2019d advocate for everyone, all the time. But every now and then, the work done when I\u2019m down to the wire is my best.\n\nKeep one toe outside your comfort zone\n\nWhen I\u2019m choosing new projects to take on, I often seek out work that involves an element of challenge. Whether it\u2019s a design problem that will require some creative thinking, or a coding project that lends itself to using new technology like HTML5, I find a manageable level of difficulty to be an added bonus. The tension that comes from learning a new skill or rethinking an old standby is a useful constraint, as it keeps the work interesting, and ensures that I continue learning.\n\nThere you have it\n\nWell, I think I\u2019ve spilled most of my crazy secrets for forcing my easily distracted brain to focus. As with everything we web workers do, there are an infinite number of ways to encourage productivity. I hope you\u2019ve found a few of these to be helpful, and please share your personal techniques in the comments.

{"rowid": 66, "title": "Solve the Hard Problems", "contents": "So, here we find ourselves on the cusp of 2016. We\u2019ve had a good year \u2013 the web is still alive, no one has switched it off yet. Clients still have websites, teenagers still have phone apps, and there continue to be plenty of online brands to meaningfully engage with each day. Good job team, high fives all round.\nAs it\u2019s the time to make resolutions, I wanted to share three small ideas to take into the new year.\nGet good at what you do\n\u201cHow do you get to Carnegie Hall?\u201d the old joke goes. \u201cPractise, practise, practise.\u201d \nWe work in an industry where there is an awful lot to learn. There\u2019s a lot to learn to get started and then once you do, there\u2019s a lot more to learn to keep your skills current. Just when you think you\u2019ve mastered something, it changes.\nThis is true of many industries, of course, but the sheer pace of change for us makes learning not an annual activity, but daily. Learning takes time, and while I\u2019m not convinced that every skill takes the fabled ten thousand hours to master, there is certainly no escaping that to remain current we must reinvest time in keeping our skills up to date.\nPicking where to spend your time\nOne of the hardest aspects of this thing of ours is just choosing what to learn. If you, like me, invested any time in learning the Less CSS preprocessor over the last few years, you\u2019ll probably now be spending your time relearning Sass instead. If you spent time learning Grunt, chances are you\u2019ll now be thinking about whether you should switch to Gulp. It\u2019s not just that there are new types of tools, there are new tools and frameworks to do the things you\u2019re already doing, but, well, differently.\nDeciding what to learn is hard and the costs of backing the wrong horse can seriously mount up; so much so that by the time you\u2019ve learned and then relearned the tools everyone says you need for your job, there\u2019s rarely enough time to spend really getting to know how best to use them.\n\u00a0Practise, practise, practise\nDo you know how you don\u2019t get to Carnegie Hall? By learning a new instrument each week. It takes time and experience to really learn something well. That goes for a new JavaScript framework as much as a violin. If you flit from one shiny new thing to another, you\u2019re destined to produce amateurish work forever.\nLearn the new thing, but then stick with it long enough to get really good at it \u2013 even if Twitter trolls try to convince you it\u2019s not cool. What\u2019s really not cool is living as a forevernoob. \nIf you\u2019re still not sure what to learn, go back to basics. Considering a new CSS or JavaScript framework? Invest that time in learning the underlying CSS or JavaScript really well instead. Those skills will stand the test of time.\nAudience and purpose\nBack when I was in school, my English teacher (a nice Welsh lady, who I appreciate more now than I did back then) used to love to remind us that every piece of writing should have an audience and a purpose. So much so that audience and purpose almost became her catch phrase. For every essay, article or letter, we were reminded to consider who we were writing it for and what we were trying to achieve. \nIt\u2019s something I think about a lot; certainly when writing, but also in almost every other creative endeavour. Asking who is this for and what am I trying to achieve applies equally to designing a logo or website, through to composing music or writing software.\nBeing productive\nIt seems like everyone wants to have a product these days. As someone who used to do client services work and now has a product company, I often talk with people who are interested in taking something they\u2019ve built in-house and turning it into a product. You know the sort of thing: a design agency with its own CMS or project management web app; the very logical thought process of: if this helps our business, maybe others will find it valuable too; the question that inevitably follows: could we turn this into a product?\nWhether consciously or not, the audience and purpose influence nearly every aspect of your creative process. Once written or designed or developed or created, revising a work to change the audience and purpose can be quite a challenge. No matter how much you want to turn the tension-building, atmospheric music for a horror film into a catchy chart hit, it\u2019s going to be a struggle. Yes, it\u2019s music, but that\u2019s neither the audience nor purpose for which it was created.\nThe same is absolutely true for your in-house tools \u2013 those were also designed for a specific audience and purpose. Your in-house CMS would have been designed with an audience of your own development team, who are busy implementing sites for clients. The purpose is to make that team more productive overall, taking into account considerations of maintaining multiple sites on a common codebase, training clients, a more mature and stable platform and all the other benefits of reusing the same code for each project. The audience is your team and the purpose increased productivity.\nThat\u2019s very different from a customer who wants to buy a polished system to use off-the-shelf. If their needs perfectly aligned with yours then they wouldn\u2019t be in the market for your product \u2013 they would have built their own.\nSometimes you hear the advice to \u201cscratch your own itch\u201d when it comes to product design. I don\u2019t completely agree. Got an itch? Great. Find other itchy people and sell them a backscratcher.\nBuilding a product, like designing a website, is a lot of work. It requires knowing your audience and purpose inside out. You can\u2019t fudge it and you can\u2019t just hope you\u2019ll find an audience for some old thing you have lying around.\nAlways consider the audience and purpose for everything you create. It\u2019s often the difference between success and failure.\nSolve the hard problems\nHuman beings have a natural tendency to avoid hard problems. In digital design (websites, software, whatever) the received wisdom is often that we can get 80% of the way towards doing the hard thing by doing something that\u2019s not very hard.\nDo you know what you get at the end of it? Paid. But nothing really great ever happens that way.\nI worked on a client project a while back where one of the big challenges was making full use of the massive image library they had built up over the years. The client had tens of thousands of photographs, along with a fair amount of video and a large MP3 audio library too. If it wasn\u2019t managed carefully, storage sizes would get out of control, content would go unattributed, and everything would get very messy very quickly.\nI could tell from the outset that this aspect of the project was going to be a constant problem. So we tackled it head-on. We designed and built a media management system to hold and process all the assets, and added an API so the content management system could talk to it. Every time the site needed a photo at a new size, it made an API request to the system and everything was handled seamlessly.\nIt was a daunting job to invest all the time and effort in building that dedicated system and API, but it really paid off. Instead of having the constant troubles of a vast library of media, it became one of the strongest parts of the project.\nTurn your hardest problems into your biggest strengths\nThere\u2019s a funny thing about hard problems. The hardest problems are the most fun to solve and have the biggest impact.\nMaybe you\u2019re the sort of person who clocks in for work, does their job and clocks out at 5pm without another thought. But I don\u2019t think you are, because you\u2019re here reading this. If you really love what you do, I don\u2019t think you can be satisfied in your work unless you\u2019re seeking out and working on those hard problems. That\u2019s where the magic is.\n\nThe new year is a helpful time to think about breaking bad habits. Whether it\u2019s smoking a bit less, or going to the gym a bit more, the ticking over of the calendar can provide the motivation for a new start. I have some suggestions for you.\n\nGet good at what you do. Practise your skills and don\u2019t just flit from one shiny thing to the next.\nRemember who you\u2019re doing it for and why. Consider the audience and purpose for everything you create.\nSolve the hard problems. It\u2019s more interesting, more satisfying, and has a greater impact.\n\nAs we move into 2016, these are the things I\u2019m going to continue to work on. Maybe you\u2019d like to join me.", "year": "2015", "author": "Drew McLellan", "author_slug": "drewmclellan", "published": "2015-12-24T00:00:00+00:00", "url": "https://24ways.org/2015/solve-the-hard-problems/", "topic": "process"}
{"rowid": 274, "title": "Adaptive Images for Responsive Designs", "contents": "So you\u2019ve been building some responsive designs and you\u2019ve been working through your checklist of things to do:\n\n\n\tYou started with the content and designed around it, with mobile in mind first.\n\tYou\u2019ve gone liquid and there\u2019s nary a px value in sight; % is your weapon of choice now.\n\tYou\u2019ve baked in a few media queries to adapt your layout and tweak your design at different window widths.\n\tYou\u2019ve made your images scale to the container width using the fluid Image technique.\n\tYou\u2019ve even done the same for your videos using a nifty bit of JavaScript.\n\n\nYou\u2019ve done a good job so pat yourself on the back. But there\u2019s still a problem and it\u2019s as tricky as it is important: image resolutions.\n\nHTML has an <img> problem\n\nCSS is great at adapting a website design to different window sizes \u2013 it allows you not only to tweak layout but also to send rescaled versions of the design\u2019s images. And you want to do that because, after all, a smartphone does not need a 1,900-pixel background image1.\n\nHTML is less great. In the same way that you don\u2019t want CSS background images to be larger than required, you don\u2019t want that happening with <img>s either. A smartphone only needs a small image but desktop users need a large one. Unfortunately <img>s can\u2019t adapt like CSS, so what do we do?\n\nWell, you could just use a high resolution image and the fluid image technique would scale it down to fit the viewport; but that\u2019s sending an image five or six times the file size that\u2019s really needed, which makes it slow to download and unpleasant to use. Smartphones are pretty impressive devices \u2013 my ancient iPhone 3G is more powerful in every way than my first proper computer \u2013 but they\u2019re still terribly slow in comparison to today\u2019s desktop machines. Sending a massive image means it has to be manipulated in memory and redrawn as you scroll. You\u2019ll find phones rapidly run out of RAM and slow to a crawl.\n\nWell, OK. You went mobile first with everything else so why not put in mobile resolution <img>s too? Because even though mobile devices are rapidly gaining share in your analytics stats, they\u2019re still not likely to be the major share of your user base. I don\u2019t think desktop users would be happy with pokey little mobile resolution images, do you? What we need are adaptive images.\n\nAdaptive image techniques\n\nThere are a number of possible solutions, each with pros and cons, and it\u2019s not as simple to find a graceful solution as you might expect.\n\nYour first thought might be to use JavaScript to trawl through the markup and rewrite the source attribute. That\u2019ll get you the right end result, but it\u2019ll have done it in a way you absolutely don\u2019t want. That\u2019s because of the way browsers load resources. It starts to load the HTML and builds the page on-the-fly; as soon as it finds an <img> element it immediately asks the server for that image. After the HTML has finished loading, the JavaScript will run, change the src attribute, and then the browser will request that new image too. Not instead of, but as well as. Not good: that\u2019s added more bloat instead of cutting it.\n\nPlain JavaScript is out then, which is a problem, because what other tools do we have to work with as web designers? Let\u2019s ignore that for now and I\u2019ll outline another issue with the concept of serving different resolution images for different window widths: a basic file management problem. To request a different image, that image has to exist on the server. How\u2019s it going to get there? That\u2019s not a trivial problem, especially if you have non-technical users that update content through a CMS. Let\u2019s say you solve that \u2013 do you plan on a simple binary switch: big image|little image? Is that really efficient or future-proof? What happens if you have an archive of existing content that needs to behave this way? Can you apply such a solution to existing content or markup?\n\nThere\u2019s a detailed round-up of potential techniques for solving the adaptive images problem over at the Cloud Four blog if you fancy a dig around exploring all the options currently available. But I\u2019m here to show you what I think is the most flexible and easy to implement solution, so here we are.\n\nAdaptive Images\n\nAdaptive Images aims to mitigate most of the issues surrounding the problems of bringing the venerable <img> tag into the 21st century. And it works by leaving that tag completely alone \u2013 just add that desktop resolution image into the markup as you\u2019ve been doing for years now. We\u2019ll fix it using secret magic techniques and bottled pixie dreams. Well, fine: with one .htaccess file, one small PHP file and one line of JavaScript. But you\u2019re killing the mystique with that kind of talk.\n\nSo, what does this solution do?\n\n\n\tIt allows <img>s to adapt to the same break points you use in your media queries, giving granular control in the same way you get with your CSS.\n\tIt installs on your server in five minutes or less and after that is automatic and you don\u2019t need to do anything.\n\tIt generates its own rescaled images on the server and doesn\u2019t require markup changes, so you can apply it to existing web content.\n\tIf you wish, it will make all of your images go mobile-first (just in case that\u2019s what you want if JavaScript and cookies aren\u2019t available).\n\n\nSound good? I hope so. Here\u2019s what you do.\n\nSetting up and rolling out\n\nI\u2019ll assume you have some basic server knowledge along with that wealth of front-end wisdom exploding out of your head: that you know not to overwrite any existing .htaccess file for example, and how to set file permissions on your server. Feeling up to it? Excellent.\n\n\n\tDownload the latest version of Adaptive Images either from the website or from the GitHub repository.\n\tUpload the included .htaccess and adaptive-images.php files into the root folder of your website.\n\tCreate a directory called ai-cache and make sure the server can write to it (CHMOD 755 should do it).\n\tAdd the following line of JavaScript into the <head> of your site:\n\n\n<script>document.cookie='resolution='+Math.max(screen.width,screen.height)+'; path=/\u2018;</script>\n\nThat\u2019s it, unless you want to tweak the default settings. You likely do, but essentially you\u2019re already up and running.\n\nHow it works\n\nAdaptive Images does a number of things depending on the scenario the script has to handle, but here\u2019s a basic overview of what it does when you load a page running it:\n\n\n\tA session cookie is written with the value of the visitor\u2019s screen size in pixels.\n\tThe HTML encounters an <img> tag and sends a request to the server for that image. It also sends the cookie, because that\u2019s how browsers work.\n\tApache sits on the server and receives the request for the image. Apache then has a look in the .htaccess file to see if there are any special instructions for files in the requested URL.\n\tThere are! The .htaccess says \u201cHey, server! Any request you get for a JPG, GIF or PNG file just send to the adaptive-images.php file instead.\u201d\n\tThe PHP file then does some intelligent thinking which can cover a number of scenarios, but I\u2019ll illustrate one path that can happen:\n\n\n\t\n\t\tThe PHP file looks for the cookie and finds out that the user has a maximum screen width of 480px.\n\t\tThe PHP has a look at the available media query sizes that were configured and decides which one matches the user\u2019s device.\n\t\tIt then has a look inside the /ai-cache/480/ folder to see if a rescaled image already exists there.\n\t\tWe\u2019ll pretend it doesn\u2019t \u2013 the PHP then goes to the actual requested URI and finds that the original file does exist.\n\t\tIt has a look to see how wide that image is. If it\u2019s already smaller than the user\u2019s screen width it sends it along and stops there. But, let\u2019s pretend the image is 1,000px wide.\n\t\tThe PHP then resizes the image and saves it into the /ai-cache/480 folder ready for the next time someone needs it.\n\t\n\nIt also does a few other things when needs arise, for example:\n\n\n\tIt sends images with a cache header field that tells proxies not to cache the image, while telling browsers they should. This avoids problems with proxy servers and network caching systems grabbing the wrong image and storing it.\n\tIt handles cases where there isn\u2019t a cookie set, and you can choose whether to then send the mobile version or the largest configured media query size.\n\tIt compares timestamps between the source image and the generated cache image \u2013 to ensure that if the source image gets updated, the old cached file won\u2019t be sent.\n\n\nCustomizing\n\nThere are a few options you can customize if you don\u2019t like the default values. By looking in the PHP\u2019s configuration section at the top of the file, you can:\n\n\n\tSet the resolution breakpoints to match your media query break points.\n\tChange the name and location of the ai-cache folder.\n\tChange the quality level any generated JPG images are saved at.\n\tHave it perform a subtle sharpen on rescaled images to help keep detail.\n\tToggle whether you want it to compare the files in the cache folder with the source ones or not.\n\tSet how long the browser should cache the images for.\n\tSwitch between a mobile-first or desktop-first approach when a cookie isn\u2019t found.\n\n\nMore importantly, you probably want to omit a few folders from the AI behaviour. You don\u2019t need or want it resizing the images you\u2019re using in your CSS, for example. That\u2019s fine \u2013 just open up the .htaccess file and follow the instructions to list any directories you want AI to ignore. Or, if you\u2019re a dab hand at RewriteRules you can remove the exclamation mark at the start of the rule and it\u2019ll only apply AI behaviour to a given list of folders.\n\nCaveats\n\nAs I mentioned, I think this is one of the most flexible, future-proof, retrofittable and easy to use solutions available today. But, there are problems with this approach as there are with all of the ones I\u2019ve seen so far.\n\nThis is a PHP solution\n\nI wish I was smarter and knew some fancy modern languages the cool kids discuss at parties, but I don\u2019t. So, you need PHP on your server. That said, Adaptive Images has a Creative Commons licence2 and I would welcome anyone to contribute a port of the code3. \n\nContent delivery networks\n\nAdaptive Images relies on the server being able to: intercept requests for images; do some logic; and send one of a given number of responses. Content delivery networks are generally dumb caches, and they won\u2019t allow that to happen. Adaptive Images will not work if you\u2019re using a CDN to deliver your website.\n\nA minor but interesting cookie issue.\n\nAs Yoav Weiss pointed out in his article Preloaders, cookies and race conditions, there is no way to guarantee that a cookie will be set before images are requested \u2013 even though the JavaScript that sets the cookie is loaded by the browser before it finds any <img> tags. That could mean images being requested without a cookie being available. Adaptive Images has a two-fold mechanism to avoid this being a problem:\n\n\n\tThe $mobile_first toggle allows you to choose what to send to a browser if a cookie isn\u2019t set. If FALSE then it will send the highest configured resolution; if TRUE it will send the lowest.\n\tEven if set to TRUE, Adaptive Images checks the User Agent String. If it discovers the user is on a desktop environment, it will override $mobile_first and set it to FALSE.\n\n\nThis means that if $mobile_first is set to TRUE and the user was unlucky (their browser didn\u2019t write the cookie fast enough), mobile devices will be supplied with the smallest image, and desktop devices will get the largest.\n\nThe best way to get a cookie written is to use JavaScript as I\u2019ve explained above, because it\u2019s the fastest way. However, for those that want it, there is a JavaScript-free method which uses CSS and a bogus PHP \u2018image\u2019 to set the cookie. A word of caution: because it requests an external file, this method is slower than the JavaScript one, and it is very likely that the cookie won\u2019t be set until after images have been requested.\n\nThe future\n\nFor today, this is a pretty good solution. It works, and as it doesn\u2019t interfere with your markup or source material in any way, the process is non-destructive. If a future solution is superior, you can just remove the Adaptive Images files and you\u2019re good to go \u2013 you\u2019d never know AI had been there.\n\nHowever, this isn\u2019t really a long-term solution, not least because of the intermittent problem of the cookie and image request race condition. What we really need are a number of standardized ways to handle this in the future.\n\nFirst, we could do with browsers sending far more information about the user\u2019s environment along with each HTTP request (device size, connection speed, pixel density, etc.), because the way things work now is no longer fit for purpose. The web now is a much broader entity used on far more diverse devices than when these technologies were dreamed up, and we absolutely require the server to have better knowledge about device capabilities than is currently possible. Relying on cookies to do this job doesn\u2019t cut it, and the User Agent String is a complete mess incapable of fulfilling the various purposes we are forced to hijack it for.\n\nSecondly, we need a W3C-backed markup level solution to supply semantically different content at different resolutions, not just rescaled versions of the same content as Adaptive Images does.\n\nI hope you\u2019ve found this interesting and will find Adaptive Images useful.\n\nFootnotes\n\n1 While I\u2019m talking about preventing smartphones from downloading resources they don\u2019t need: you should be careful of your media query construction if you want to stop WebKit downloading all the images in all of the CSS files.\n\n2 Adaptive Images has a very broad Creative Commons licence and I warmly welcome feedback and community contributions via the GitHub repository. \n\n3 There is a ColdFusion port of an older version of Adaptive Images.

{"rowid": 99, "title": "A Christmas hCard From Me To You", "contents": "So apparently Christmas is coming. And what is Christmas all about? Well, cleaning out your address book, of course! What better time to go through your contacts, making sure everyone\u2019s details are up date and that you\u2019ve deleted all those nasty clients who never paid on time?\n\nIt\u2019s also a good time to make sure your current clients and colleagues have your most up-to-date details, so instead of filling up their inboxes with e-cards, why not send them something useful? Something like a\u2026 vCard! (See what I did there?)\n\nJust in case you\u2019ve been working in a magical toy factory in the upper reaches of Scandinavia for the last few years, I\u2019m going to tell you that now would also be the perfect time to get into microformats. Using the hCard format, we\u2019ll build a very simple web page and markup our contact details in such a way that they\u2019ll be understood by microformats plugins, like Operator or Tails for Firefox, or the cross-browser Microformats Bookmarklet.\n\nOh, and because Christmas is all about dressing up and being silly, we\u2019ll make the whole thing look nice and have a bit of fun with some CSS3 progressive enhancement. \n\nIf you can\u2019t wait to see what we end up with, you can preview it here.\n\n\n\nStep 1: Contact Details\n\nFirst, let\u2019s decide what details we want to put on the page. I\u2019d put my full name, my email address, my phone number, and my postal address, but I\u2019d rather not get surprise visits from strangers when I\u2019m fannying about with my baubles, so I\u2019m going to use Father Christmas instead (that\u2019s Santa to you Yanks).\n\nFather Christmas\nfatherchristmas@elliotjaystocks.com\n25 Laughingallthe Way\nSnow Falls\nLapland\nFinland\n010 60 58 000\n\nStep 2: hCard Creator\n\nNow I\u2019m not sure about you, but I rather like getting the magical robot pixies to do the work for me, so head on over to the hCard Creator and put those pixies to work! Pop in your details and they\u2019ll give you some nice microformatted HTML in turn.\n\n\n\n<div id=\"hcard-Father-Christmas\" class=\"vcard\">\n\t<a class=\"url fn\" href=\"http://elliotjaystocks.com/fatherchristmas\">Father Christmas</a>\n\t<a class=\"email\" href=\"mailto:fatherchristmas@elliotjaystocks.com\"> fatherchristmas@elliotjaystocks.com</a>\n\t<div class=\"adr\">\n\t<div class=\"street-address\">25 Laughingallthe Way</div>\n\t<span class=\"locality\">Snow Falls</span>\n\t, \n\t<span class=\"region\">Lapland</span>\n\t, \n\t<span class=\"postal-code\">FI-00101</span>\n\t<span class=\"country-name\">Finland</span>\n</div>\n<div class=\"tel\">010 60 58 000</div>\n\t<p style=\"font-size:smaller;\">This <a href=\"http://microformats.org/wiki/hcard\">hCard</a> created with the <a href=\"http://microformats.org/code/hcard/creator\">hCard creator</a>.</p>\n</div>\n\nStep 3: Editing The Code\n\nOne of the great things about microformats is that you can use pretty much whichever HTML tags you want, so just because the hCard Creator Fairies say something should be wrapped in a <span> doesn\u2019t mean you can\u2019t change it to a <blink>. Actually, no, don\u2019t do that. That\u2019s not even excusable at Christmas.\n\nI personally have a penchant for marking up each line of an address inside a <li> tag, where the parent url retains the class of adr. As long as you keep the class names the same, you\u2019ll be fine.\n\n<div id=\"hcard-Father-Christmas\" class=\"vcard\">\n\t<h1><a class=\"url fn\" href=\"http://elliotjaystocks.com/fatherchristmas\">Father Christmas </a></h1>\n\t<a class=\"email\" href=\"mailto:fatherchristmas@elliotjaystocks.com?subject=Here, have some Christmas cheer!\">fatherchristmas@elliotjaystocks.com</a>\n\t<ul class=\"adr\">\n\t\t<li class=\"street-address\">25 Laughingallthe Way</li>\n\t\t<li class=\"locality\">Snow Falls</li>\n\t\t<li class=\"region\">Lapland</li>\n\t\t<li class=\"postal-code\">FI-00101</li>\n\t\t<li class=\"country-name\">Finland</li>\n\t</ul>\n\t<span class=\"tel\">010 60 58 000</span>\n</div>\n\nStep 4: Testing The Microformats\n\nWith our microformats in place, now would be a good time to test that they\u2019re working before we start making things look pretty. If you\u2019re on Firefox, you can install the Operator or Tails extensions, but if you\u2019re on another browser, just add the Microformats Bookmarklet. Regardless of your choice, the results is the same: if you\u2019ve code microformatted content on a web page, one of these bad boys should pick it up for you and allow you to export the contact info. Give it a try and you should see father Christmas appearing in your address book of choice. Now you\u2019ll never forget where to send those Christmas lists!\n\n\n\nStep 5: Some Extra Markup\n\nOne of the first things we\u2019re going to do is put a photo of Father Christmas on the hCard. We\u2019ll be using CSS to apply a background image to a div, so we\u2019ll be needing an extra div with a class name of \u201cphoto\u201d. In turn, we\u2019ll wrap the text-based elements of our hCard inside a div cunningly called \u201ctext\u201d. Unfortunately, because of the float technique we\u2019ll be using, we\u2019ll have to use one of those nasty float-clearing techniques. I shall call this \u201cchristmas-cheer\u201d, since that is what its presence will inevitably bring, of course.\n\nOh, and let\u2019s add a bit of text to give the page context, too:\n\n<p>Send your Christmas lists my way...</p>\n<div id=\"hcard-Father-Christmas\" class=\"vcard\">\n\t<div class=\"text\">\n\t\t<h1><a class=\"url fn\" href=\"http://elliotjaystocks.com/fatherchristmas\">Father Christmas </a></h1>\n\t\t<a class=\"email\" href=\"mailto:fatherchristmas@elliotjaystocks.com?subject=Here, have some Christmas cheer!\">fatherchristmas@elliotjaystocks.com</a>\n\t\t<ul class=\"adr\">\n\t\t\t<li class=\"street-address\">25 Laughingallthe Way</li>\n\t\t\t<li class=\"locality\">Snow Falls</li>\n\t\t\t<li class=\"region\">Lapland</li>\n\t\t\t<li class=\"postal-code\">FI-00101</li>\n\t\t\t<li class=\"country-name\">Finland</li>\n\t\t</ul>\n\t\t<span class=\"tel\">010 60 58 000</span>\n\t</div>\n\t<div class=\"photo\"></div>\n\t<br class=\"christmas-cheer\" />\n</div>\n<div class=\"credits\">\n\t<p>A tutorial by <a href=\"http://elliotjaystocks.com\">Elliot Jay Stocks</a> for <a href=\"http://24ways.org/\">24 Ways</a></p>\n\t<p>Background: <a href=\"http://sxc.hu/photo/1108741\">stock.xchng</a> | Father Christmas: <a href=\"http://istockphoto.com/file_closeup/people/4575943-active-santa.php?id=4575943\">iStockPhoto</a></p>\n</div>\n\nStep 6: Some Christmas Sparkle\n\nSo far, our hCard-housing web page is slightly less than inspiring, isn\u2019t it? It\u2019s time to add a bit of CSS. There\u2019s nothing particularly radical going on here; just a simple layout, some basic typographic treatment, and the placement of the Father Christmas photo. I\u2019d usually use a more thorough CSS reset like the one found in the YUI or Eric Meyer\u2019s, but for this basic page, the simple * solution will do.\n\nCheck out the step 6 demo to see our basic styles in place.\n\nFrom this\u2026\n\n\n\n\u2026 to this:\n\n\n\nStep 7: Fun With imagery\n\nNow it\u2019s time to introduce a repeating background image to the <body> element. This will seamlessly repeat for as wide as the browser window becomes.\n\nBut that\u2019s fairly straightforward. How about having some fun with the Father Christmas image? If you look at the image file itself, you\u2019ll see that it\u2019s twice as wide as the area we can see and contains a \u2018hidden\u2019 photo of our rather camp St. Nick.\n\n\n\nAs a light-hearted visual\u2026 er\u2026 \u2018treat\u2019 for users who move their mouse over the image, we move the position of the background image on the \u201cphoto\u201d div. Check out the step 7 demo to see it working.\n\nStep 8: Progressive Enhancement\n\nFinally, this fun little project is a great opportunity for us to mess around with some advanced CSS features (some from the CSS3 spec) that we rarely get to use on client projects. (Don\u2019t forget: no Christmas pressies for clients who want you to support IE6!)\n\nHere are the rules we\u2019re using to give some browsers a superior viewing experience:\n\n\n\t@font-face allows us to use Jos Buivenga\u2019s free font \u2018Fertigo Pro\u2019 on all text;\n\ttext-shadow adds a little emphasis on the opening paragraph;\n\tbody > p:first-child causes only the first paragraph to receive this treatment;\n\tborder-radius created rounded corners on our main div and the links within it;\n\tand webkit-transition allows us to gently fade in between the default and hover states of those links.\n\n\nAnd with that, we\u2019re done! You can see the results here. It\u2019s time to customise the page to your liking, upload it to your site, and send out the URL. And do it quickly, because I\u2019m sure you\u2019ve got some last-minute Christmas shopping to finish off!", "year": "2008", "author": "Elliot Jay Stocks", "author_slug": "elliotjaystocks", "published": "2008-12-10T00:00:00+00:00", "url": "https://24ways.org/2008/a-christmas-hcard-from-me-to-you/", "topic": "code"}
{"rowid": 305, "title": "CSS Writing Modes", "contents": "Since you may not have a lot of time, I\u2019m going to start at the end, with the dessert.\nYou can use a little-known, yet important and powerful CSS property to make text run vertically. Like this.\n\nOr instead of running text vertically, you can layout a set of icons or interface buttons in this way. Or, of course, with anything on your page.  \nThe CSS I\u2019ve applied makes the browser rethink the orientation of the world, and flow the layout of this element at a 90\u00b0 angle to \u201cnormal\u201d. Check out the live demo, highlight the headline, and see how the cursor is now sideways.\nSee the Pen Writing Mode Demo \u2014 Headline by Jen Simmons (@jensimmons) on CodePen.\n\nThe code for accomplishing this is pretty simple. \nh1 { \n  writing-mode: vertical-rl;\n}\nThat\u2019s all it takes to switch the writing mode from the web\u2019s default horizontal top-to-bottom mode to a vertical right-to-left mode. If you apply such code to the html element, the entire page is switched, affecting the scroll direction, too. \nIn my example above, I\u2019m telling the browser that only the h1 will be in this vertical-rl mode, while the rest of my page stays in the default of horizontal-tb.\nSo now the dessert course is over. Let me serve up this whole meal, and explain the the CSS Writing Mode Specification.\nWhy learn about writing modes?\nThere are three reasons I\u2019m teaching writing modes to everyone\u2014including western audiences\u2014and explaining the whole system, instead of quickly showing you a simple trick.\n\n\nWe live in a big, diverse world, and learning about other languages is fascinating. Many of you lay out pages in languages like Chinese, Japanese and Korean. Or you might be inspired to in the future.\n\n\nUsing writing-mode to turn bits sideways is cool. This CSS can be used in all kinds of creative ways, even if you are working only in English.\n\nMost importantly, I\u2019ve found understanding Writing Modes incredibly helpful when understanding Flexbox and CSS Grid. Before I learned Writing Mode, I felt like there was still a big hole in my knowledge, something I just didn\u2019t get about why Grid and Flexbox work the way they do. Once I wrapped my head around Writing Modes, Grid and Flexbox got a lot easier. Suddenly the Alignment properties, align-* and justify-*, made sense.\n\nWhether you know about it or not, the writing mode is the first building block of every layout we create. You can do what we\u2019ve been doing for 25 years \u2013 and leave your page set to the default left-to-right direction, horizontal top-to-bottom writing mode. Or you can enter a world of new possibilities where content flows in other directions.\nCSS properties\nI\u2019m going to focus on the CSS writing-mode property in this article. It has five possible options:\n  writing-mode: horizontal-tb;\n  writing-mode: vertical-rl;\n  writing-mode: vertical-lr;\n  writing-mode: sideways-rl;\n  writing-mode: sideways-lr;\nThe CSS Writing Modes Specification is designed to support a wide range of written languages in all our human and linguistic complexity. Which\u2014spoiler alert\u2014is pretty insanely complex. The global evolution of written languages has been anything but simple. \nSo I\u2019ve got to start with explaining some basic concepts of web page layout and writing systems. Then I can show you what these CSS properties do. \nInline Direction, Block Direction, and Character Direction\nIn the world of the web, there\u2019s a concept of \u2018block\u2019 and \u2018inline\u2019 layout. If you\u2019ve ever written display: block or display: inline, you\u2019ve leaned on these concepts.  \nIn the default writing mode, blocks stack vertically starting at the top of the page and working their way down. Think of how a bunch of block-levels elements stack\u2014like a bunch of a paragraphs\u2014that\u2019s the block direction. \n\nInline is how each line of text flows. The default on the web is from left to right, in horizontal lines. Imagine this text that you are reading right now, being typed out one character at a time on a typewriter. That\u2019s the inline direction. \n\nThe character direction is which way the characters point. If you type a capital \u201cA\u201d for instance, on which side is the top of the letter? Different languages can point in different directions. Most languages have their characters pointing towards the top of the page, but not all.\n\nPut all three together, and you start to see how they work as a system. \nThe default settings for the web work like this.\nNow that we know what block, inline, and character directions mean, let\u2019s see how they are used in different writing systems from around the world.\nThe four writing systems of CSS Writing Modes\nThe CSS Writing Modes Specification handles all the use cases for four major writing systems; Latin, Arabic, Han and Mongolian. \nLatin-based systems\nOne writing system dominates the world more than any other, reportedly covering about 70% of the world\u2019s population. \n\nThe text is horizontal, running from left to right, or LTR. The block direction runs from top to bottom. \nIt\u2019s called the Latin-based system because it includes all languages that use the Latin alphabet, including English, Spanish, German, French, and many others. But there are many non-Latin-alphabet languages that also use this system, including Greek, Cyrillic (Russian, Ukrainian, Bulgarian, Serbian, etc.), and Brahmic scripts (Devanagari, Thai, Tibetan), and many more.\nYou don\u2019t need to do anything in your CSS to trigger this mode. This is the default. \nBest practices, however, dictate that you declare in your opening <html> element which language and which direction (LTR or RTL) you are using. This website, for instance, uses <html lang='en-gb' dir='ltr'> to let the browser know this content is published in Great Britian\u2019s version of English, in a left to right direction. \nArabic-based systems\nArabic, Hebrew and a few other languages run the inline direction from right to left. This is commonly known as RTL.  \nNote that the inline direction still runs horizontally. The block direction runs from top to bottom. And the characters are upright.\n\nIt\u2019s not just the flow of text that runs from right to left, but everything about the layout of the website. The upper right-hand corner is the starting position. Important things are on the right. The eyes travel from right to left. So, typically RTL websites use layouts that are just like LTR websites, only flipped.\nOn websites that support both LTR and RTL, like the United Nations\u2019 site at un.org, the two layouts are mirror images of each other.\nFor many web developers, our experiences with internationalization have focused solely on supporting Arabic and Hebrew script. \nCSS layout hacks for internationalization & RTL\nTo prepare an LTR project to support RTL, developers have had to create all sorts of hacks. For example, the Drupal community started a convention of marking every margin-left and -right, every padding-left and -right, every float: left and float: right with the comment /* LTR */. Then later developers could search for each instance of that exact comment, and create stylesheets to override each left with right, and vice versa. It\u2019s a tedious and error prone way to work. CSS itself needed a better way to let web developers write their layout code once, and easily switch language directions with a single command.\nOur new CSS layout system does exactly that. Flexbox, Grid and Alignment use start and end instead of left and right. This lets us define everything in relationship to the writing system, and switch directions easily. By writing justify-content: flex-start, justify-items: end, and eventually margin-inline-start: 1rem we have code that doesn\u2019t need to be changed. \nThis is a much better way to work. I know it can be confusing to think through start and end as replacements for left and right. But it\u2019s better for any multiligual project, and it\u2019s better for the web as a whole.\nSadly, I\u2019ve seen CSS preprocessor tools that claim to \u201cfix\u201d the new CSS layout system by getting rid of start and end and bringing back left and right. They want you to use their tool, write justify-content: left, and feel self-righteous. It seems some folks think the new way of working is broken and should be discarded. It was created, however, to fulfill real needs. And to reflect a global internet. As Bruce Lawson says, WWW stands for the World Wide Web, not the Wealthy Western Web. Please don\u2019t try to convince the industry that there\u2019s something wrong with no longer being biased towards western culture. Instead, spread the word about why this new system is here.  \nSpend a bit of time drilling the concept of inline and block into your head, and getting used to start and end. It will be second nature soon enough. \nI\u2019ve also seen CSS preprocessors that let us use this new way of thinking today, even as all the parts aren\u2019t fully supported by browsers yet. Some tools let you write text-align: start instead of text-align: left, and let the preprocessor handle things for you. That is terrific, in my opinion. A great use of the power of a preprocessor to help us switch over now. \nBut let\u2019s get back to RTL. \nHow to declare your direction\nYou don\u2019t want to use CSS to tell the browser to switch from an LTR language to RTL. You want to do this in your HTML. That way the browser has the information it needs to display the document even if the CSS doesn\u2019t load.\nThis is accomplished mainly on the html element. You should also declare your main language. As I mentioned above, the 24 ways website is using <html lang='en-gb' dir='ltr'> to declare the LTR direction and the use of British English. The UN Arabic website uses <html lang='ar' dir='rtl'>to declare the site as an Arabic site, using a RTL layout. \nThings get more complicated when you\u2019ve got a page with a mix of languages. But I\u2019m not going to get into all of that, since this article is focused on CSS and layouts, not explaining everything about internationalization. \nLet me just leave direction here by noting that much of the heavy work of laying out the characters which make up each word is handled by Unicode. If you are interested in learning more about LTR, RTL and bidirectional text, watch this video: Introduction to Bidirectional Text, a presentation by Elika Etemad. \nMeanwhile, let\u2019s get back to CSS.\nThe writing mode CSS for Latin-based and Arabic-based systems\nFor both of these systems\u2014Latin-based and Arabic-based, whether LTR or RTL\u2014the same CSS property applies for specifying the writing mode: writing-mode: horizontal-tb. That\u2019s because in both systems, the inline text flow is horizontal, while the block direction is top-to-bottom. This is expressed as horizontal-tb.\nhorizontal-tb is the default writing mode for the web, so you don\u2019t need to specify it unless you are overriding something else higher up in the cascade. You can just imagine that every site you\u2019ve ever built came with:\nhtml {\n  writing-mode: horizontal-tb;\n}\nNow let\u2019s turn our attention to the vertical writing systems. \nHan-based systems\nThis is where things start to get interesting. \nHan-based writing systems include CJK languages, Chinese, Japanese, Korean and others. There are two options for laying out a page, and sometimes both are used at the same time.\nMuch of CJK text is laid out like Latin-based languages, with a horizontal top-to-bottom block direction, and a left-to-right inline direction. This is the more modern way to doing things, started in the 20th century in many places, and further pushed into domination by the computer and later the web. \nThe CSS to do this bit of the layouts is the same as above:\nsection {\n  writing-mode: horizontal-tb;\n}\nOr, you know, do nothing, and get that result as a default. \nAlternatively Han-based languages can be laid out in a vertical writing mode, where the inline direction runs vertically, and the block direction goes from right to left. \nSee both options in this diagram:\n\nNote that the horizontal text flows from left to right, while the vertical text flows from right to left. Wild, eh? \nThis Japanese issue of Vogue magazine is using a mix of writing modes. The cover opens on the left spine, opposite of what an English magazine does.  \n\nThis page mixes English and Japanese, and typesets the Japanese text in both horizontal and vertical modes. Under the title \u201cRichard Stark\u201d in red, you can see a passage that\u2019s horizontal-tb and LTR, while the longer passage of text at the bottom of the page is typeset vertical-rl. The red enlarged cap marks the beginning of that passage. The long headline above the vertical text is typeset LTR, horizontal-tb.\n\nThe details of how to set the default of the whole page will depend on your use case. But each element, each headline, each section, each article can be marked to flow the opposite of the default however you\u2019d like.\nFor example, perhaps you leave the default as horizontal-tb, and specify your vertical elements like this:\ndiv.articletext {\n  writing-mode: vertical-rl;\n}\nOr alternatively you could change the default for the page to a vertical orientation, and then set specific elements to horizontal-tb, like this:\nhtml { \n  writing-mode: vertical-rl;\n}\nh2, .photocaptions, section {\n  writing-mode: horizontal-tb;\n}\nIf your page has a sideways scroll, then the writing mode will determine whether the page loads with upper left corner as the starting point, and scroll to the right (horizontal-tb as we are used to), or if the page loads with the upper right corner as the starting point, scrolling to the left to display overflow. Here\u2019s an example of that change in scrolling direction, in a CSS Writing Mode demo by Chen Hui Jing. Check out her demo \u2014 you can switch from horizontal to vertical writing modes with a checkbox and see the difference. \n\nMongolian-based systems\nNow, hopefully so far all of this kind of makes sense. It might be a bit more complicated than expected, but it\u2019s not so hard. Well, enter the Mongolian-based systems.\nMongolian is also a vertical script language. Text runs vertically down the page. Just like Han-based systems. There are two major differences. First, the block direction runs the other way. In Mongolian, block-level elements stack from left to right. \nHere\u2019s a drawing of how Wikipedia would look in Mongolian if it were laid out correctly.\nPerhaps the Mongolian version of Wikipedia will be redone with this layout.\nNow you might think, that doesn\u2019t look so weird. Tilt your head to the left, and it\u2019s very familiar. The block direction starts on the left side of the screen and goes to the right. The inline direction starts on the top of the page and moves to the bottom (similar to RTL text, just turned 90\u00b0 counter-clockwise). But here comes the other huge difference. The character direction is \u201cupside down\u201d. The top of the Mongolian characters are not pointing to the left, towards the start edge of the block direction. They point to the right. Like this:\n\nNow you might be tempted to ignore all this. Perhaps you don\u2019t expect to be typesetting Mongolian content anytime soon. But here\u2019s why this is important for everyone \u2014 the way Mongolian works defines the results writing-mode: vertical-lr. And it means we cannot use vertical-lr for typesetting content in other languages in the way we might otherwise expect. \nIf we took what we know about vertical-rl and guessed how vertical-lr works, we might imagine this:\n\nBut that\u2019s wrong. Here\u2019s how they actually compare:\n\nSee the unexpected situation? In both writing-mode: vertical-rl and writing-mode: vertical-lr latin text is rotated clockwise. Neither writing mode let\u2019s us rotate text counter-clockwise. \nIf you are typesetting Mongolian content, apply this CSS in the same way you would apply writing-mode to Han-based writing systems. To the whole page on the html element, or to specific pages of the page like this:\nsection {\n  writing-mode: vertical-lr;\n}\nNow, if you are using writing-mode for a graphic design effect on a language that is otherwise typesets horizontally, I don\u2019t think writing-mode: vertical-lr is useful. If the text wraps onto two lines, it stacks in a very unexpected way. So I\u2019ve sort of obliterated it from my toolkit. I find myself using writing-mode: vertical-rl a lot. And never using -lr. Hm.\nWriting modes for graphic design\nSo how do we use writing-mode to turn English headlines sideways? We could rely on transform: rotate()\nHere are two examples, one for each direction. (By the way, each of these demos use CSS Grid for their overall layout, so be sure to test them in a browser that supports CSS Grid, like Firefox Nightly.)\n\nIn this demo 4A, the text is rotated clockwise using this code: \nh1 {\n  writing-mode: vertical-rl;\n}\n\nIn this demo 4B, the text is rotated counter-clockwise using this code: \nh1 {\n  writing-mode: vertical-rl;\n  transform: rotate(180deg);\n  text-align: right;\n}\nI use vertical-rl to rotate the text so that it takes up the proper amount of space in the overall flow of the layout. Then I rotate it 180\u00b0 to spin it around to the other direction. And then I use text-align: right to get it to rise up to the top of it\u2019s container. This feels like a hack, but it\u2019s a hack that works.\nNow what I would like to do instead is use another CSS value that was designed for this use case \u2014 one of the two other options for writing mode.\nIf I could, I would lay out example 4A with:\nh1 {\n  writing-mode: sideways-rl;\n}\nAnd layout example 4B with: \nh1 {\n  writing-mode: sideways-lr;\n}\nThe problem is that these two values are only supported in Firefox. None of the other browsers recognize sideways-*. Which means we can\u2019t really use it yet. \nIn general, the writing-mode property is very well supported across browsers. So I\u2019ll use writing-mode: vertical-rl for now, with the transform: rotate(180deg); hack to fake the other direction. \nThere\u2019s much more to what we can do with the CSS designed to support multiple languages, but I\u2019m going to stop with this intermediate introduction. \nIf you do want a bit more of a taste, look at this example that adds text-orientation: upright; to the mix \u2014 turning the individual letters of the latin font to be upright instead of sideways.\n\nIt\u2019s this demo 4C, with this CSS applied: \nh1 {\n  writing-mode: vertical-rl;\n  text-orientation: upright;\n  text-transform: uppercase;\n  letter-spacing: -25px;\n}\nYou can check out all my Writing Modes demos at labs.jensimmons.com/#writing-modes. \n\nI\u2019ll leave you with this last demo. One that applies a vertical writing mode to the sub headlines of a long article. I like how small details like this can really bring a fresh feeling to the content. \nSee the Pen Writing Mode Demo \u2014 Article Subheadlines by Jen Simmons (@jensimmons) on CodePen.", "year": "2016", "author": "Jen Simmons", "author_slug": "jensimmons", "published": "2016-12-23T00:00:00+00:00", "url": "https://24ways.org/2016/css-writing-modes/", "topic": "code"}
{"rowid": 220, "title": "Finding Your Way with Static Maps", "contents": "Since the introduction of the Google Maps service in 2005, online maps have taken off in a way not really possible before the invention of slippy map interaction. Although quickly followed by a plethora of similar services from both commercial and non-commercial parties, Google\u2019s first-mover advantage, and easy-to-use developer API saw Google Maps become pretty much the de facto mapping service.\n\n\n\nIt\u2019s now so easy to add a map to a web page, there\u2019s no reason not to. Dropping an iframe map into your page is as simple as embedding a YouTube video.\n\nBut there\u2019s one crucial drawback to both the solution Google provides for you to drop into your page and the code developers typically implement themselves \u2013 they don\u2019t work without JavaScript.\n\nA bit about JavaScript\n\nBack in October of this year, The Yahoo! Developer Network blog ran some tests to measure how many visitors to the Yahoo! home page didn\u2019t have JavaScript available or enabled in their browser. It\u2019s an interesting test when you consider that the audience for the Yahoo! home page (one of the most visited pages on the web) represents about as mainstream a sample as you\u2019ll find. If there\u2019s any such thing as an \u2018average Web user\u2019 then this is them.\n\nThe results surprised me. It varied from region to region, but at most just two per cent of visitors didn\u2019t have JavaScript running. To be honest, I was expecting it to be higher, but this quote from the article caught my attention:\n\n\n\tWhile the percentage of visitors with JavaScript disabled seems like a low number, keep in mind that small percentages of big numbers are also big numbers.\n\n\nThat\u2019s right, of course, and it got me thinking about what that two per cent means. For many sites, two per cent is the number of visitors using the Opera web browser, using IE6, or using Mobile Safari. \n\nSo, although a small percentage of the total, users without JavaScript can\u2019t just be forgotten about, and catering for them is at the very heart of how the web is supposed to work.\n\nStarting with content in HTML, we layer on presentation with CSS and then enhance interactivity with JavaScript. If anything fails along the way or the network craps out, or a browser just doesn\u2019t support one of the technologies, the user still gets something they can work with. \n\nIt\u2019s progressive enhancement \u2013 also known as doing our jobs properly.\n\nSorry, wasn\u2019t this about maps?\n\nAs I was saying, the default code Google provides, and the example code it gives to developers (which typically just gets followed \u2018as is\u2019) doesn\u2019t account for users without JavaScript. No JavaScript, no content.\n\nWhen adding the ability to publish maps to our small content management system Perch, I didn\u2019t want to provide a solution that only worked with JavaScript. I had to go looking for a way to provide maps without JavaScript, too.\n\nThere\u2019s a simple solution, fortunately, in the form of static map tiles. All the various slippy map services use a JavaScript interface on top of what are basically rendered map image tiles. Dragging the map loads in more image tiles in the direction you want to view. If you\u2019ve used a slippy map on a slow connection, you\u2019ll be familiar with seeing these tiles load in one by one.\n\nThe Static Map API\n\nThe good news is that these tiles (or tiles just like them) can be used as regular images on your site. Google has a Static Map API which not only gives you a handy interface to retrieve a tile for the exact area you need, but also allows you to place pins, and zoom and centre the tile so that the image looks just so. \n\nThis means that you can create a static, non-JavaScript version of your slippy map\u2019s initial (or ideal) state to load into your page as a regular image, and then have the JavaScript map hijack the image and make it slippy.\n\nClearly, that\u2019s not going to be a perfect solution for every map\u2019s requirements. It doesn\u2019t allow for panning, zooming or interrogation without JavaScript. However, for the majority of straightforward map uses online, a static map makes a great alternative for those visitors without JavaScript.\n\n\n\nHere\u2019s the how\n\nRetrieving a static map tile is staggeringly easy \u2013 it\u2019s just a case of forming a URL with the correct arguments and then using that as the src of an image tag.\n\n<img src=\"http://maps.google.com/maps/api/staticmap\n\t?center=Bethlehem+Israel\n\t&zoom=5\n\t&size=540x280\n\t&maptype=satellite\n\t&markers=color:red|31.4211,35.1144\n\t&sensor=false\" \n\twidth=\"540\" height=\"280\" alt=\"Map of Bethlehem, Israel\" />\n\nAs you can see, there are a few key options that we pass along to the base URL. All of these should be familiar to anyone who\u2019s worked with the JavaScript API.\n\n\n\tcenter determines the point on which the map is centred. This can be latitude and longitude values, or simply an address which is then geocoded.\n\tzoom sets the zoom level.\n\tsize is the pixel dimensions of the image you require.\n\tmaptype can be roadmap, satellite, terrain or hybrid.\n\tmarkers sets one or more pin locations. Markers can be labelled, have different colours, and so on \u2013 there\u2019s quite a lot of control available.\n\tsensor states whether you are using a sensor to determine the user\u2019s location. When just embedding a map in a web page, set this to false.\n\n\nThere are many options, including plotting paths and setting the image format, which can all be found in the straightforward documentation.\n\nAdding to your page\n\nIf you\u2019ve worked with the JavaScript API, you\u2019ll know that it needs a container element which you inject the map into:\n\n<div id=\"map\"></div>\n\nAll you need to do is put your static image inside that container:\n\n<div id=\"map\">\n   <img src=\"http://maps.google.com/maps/api/staticmap[...]\" />\n </div>\n\nAnd then, in your JavaScript, find the image and remove it. For example, with jQuery you\u2019d simply use:\n\n$('#map img').remove();\n\nWhy not use a <noscript> element around the image? You could, and that would certainly work fine for browsers that do not support JavaScript. What that won\u2019t cover, however, is the situation where the browser has JavaScript support but, for whatever reason, the JavaScript doesn\u2019t run. This could be due to network issues, an aggressive corporate firewall, or even just a bug in your code. So for that reason, we put the image in for all browsers that show images, and then remove it when the JavaScript is  successfully running.\n\nSee an example in action\n\nAbout rate limits\n\nThe Google Static Map API limits the requests per site viewer \u2013 currently at one thousand distinct maps per day per viewer. So, for most sites you really don\u2019t need to worry about the rate limit. Requests for the same tile aren\u2019t normally counted, as the tile has already been generated and is cached. You can embed the images direct from Google and let it worry about the distribution and caching.\n\nIn conclusion\n\nAs you can see, adding a static map alongside your dynamic map for those users without JavaScript is very easy indeed. There may not be a huge percentage of web visitors browsing without JavaScript but, as we\u2019ve seen, a small percentage of a big number is still a big number. When it\u2019s so easy to add a static map, can you really justify not doing it?", "year": "2010", "author": "Drew McLellan", "author_slug": "drewmclellan", "published": "2010-12-01T00:00:00+00:00", "url": "https://24ways.org/2010/finding-your-way-with-static-maps/", "topic": "code"}
{"rowid": 110, "title": "Shiny Happy Buttons", "contents": "Since Mac OS X burst onto our screens, glossy, glassy, shiny buttons have been almost de rigeur, and have essentially, along with reflections and rounded corners, become a clich\u00e9 of Web 2.0 \u201cdesign\u201d. But if you can\u2019t beat \u2018em you\u2019d better join \u2018em. So, in this little contribution to our advent calendar, we\u2019re going to take a plain old boring HTML button, and 2.0 it up the wazoo. \n\nBut, here\u2019s the catch. We\u2019ll use no images, either in our HTML or our CSS. No sliding doors, no image replacement techniques. Just straight up, CSS, CSS3 and a bit of experimental CSS. And, it will be compatible with pretty much any browser (though with some progressive enhancement for those who keep up with the latest browsers).\n\nThe HTML\n\nWe\u2019ll start with our HTML.\n\n<button type=\"submit\">This is a shiny button</button>\n\nOK, so it\u2019s not shiny yet \u2013 but boy will it ever be.\n\nBefore styling, that\u2019s going to look like this.\n\nIronically, depending on the operating system and browser you are using, it may well be a shiny button already, but that\u2019s not the point. We want to make it shiny 2.0. Our mission is to make it look something like this\n\n\n\nIf you want to follow along at home keep in mind that depending on which browser you are using you may see fewer of the CSS effects we\u2019ve added to create the button. As of writing, only in Safari are all the effects we\u2019ll apply supported.\n\nTaking a look at our finished product, here\u2019s what we\u2019ve done to it:\n\n\n\tWe\u2019ve given the button some padding and a width.\n\tWe\u2019ve changed the text color, and given the text a drop shadow.\n\tWe\u2019ve given the button a border.\n\tWe\u2019ve given the button some rounded corners.\n\tWe\u2019ve given the button a drop shadow.\n\tWe\u2019ve given the button a gradient background.\n\n\nand remember, all without using any images.\n\nStyling the button\n\nSo, let\u2019s get to work.\n\nFirst, we\u2019ll add given the element some padding and a width:\n\nbutton {\n\tpadding: .5em;\n\twidth: 15em;\n}\n\nNext, we\u2019ll add the text color, and the drop shadow:\n\ncolor: #ffffff;\ntext-shadow: 1px 1px 1px #000;\n\nA note on text-shadow\n\nIf you\u2019ve not seen text-shadows before well, here\u2019s the quick back-story. Text shadow was introduced in CSS2, but only supported in Safari (version 1!) some years later. It was removed from CSS2.1, but returned in CSS3 (in the text module). It\u2019s now supported in Safari, Opera and Firefox (3.1). Internet Explorer has a shadow filter, but the syntax is completely different.\n\nSo, how do text-shadows work? The three length values specify respectively a horizontal offset, a vertical offset and a blur (the greater the number the more blurred the shadow will be), and finally a color value for the shadow.\n\nRounding the corners\n\nNow we\u2019ll add a border, and round the corners of the element:\n\nborder: solid thin #882d13;\n-webkit-border-radius: .7em;\n-moz-border-radius: .7em;\nborder-radius: .7em;\n\nHere, we\u2019ve used the same property in three slightly different forms. We add the browser specific prefix for Webkit and Mozilla browsers, because right now, both of these browsers only support border radius as an experimental property. We also add the standard property name, for browsers that do support the property fully in the future. \n\nThe benefit of the browser specific prefix is that if a browser only partly supports a given property, we can easily avoid using the property with that browser simply by not adding the browser specific prefix. At present, as you might guess, border-radius is supported in Safari and Firefox, but in each the relevant prefix is required.\n\nborder-radius takes a length value, such as pixels. (It can also take two length values, but that\u2019s for another Christmas.) In this case, as with padding, I\u2019ve used ems, which means that as the user scales the size of text up and down, the radius will scale as well. You can test the difference by making the radius have a value of say 5px, and then zooming up and down the text size. \n\nWe\u2019re well and truly on the way now. All we need to do is add a shadow to the button, and then a gradient background.\n\nIn CSS3 there\u2019s the box-shadow property, currently only supported in Safari 3. It\u2019s very similar to text-shadow \u2013 you specify a horizontal and vertical offset, a blur value and a color.\n\n-webkit-box-shadow: 2px 2px 3px #999; \nbox-shadow: 2px 2px 2px #bbb;\n\nOnce more, we require the \u201cexperimental\u201d -webkit- prefix, as Safari\u2019s support for this property is still considered by its developers to be less than perfect.\n\nGradient Background\n\nSo, all we have left now is to add our shiny gradient effect. Now of course, people have been doing this kind of thing with images for a long time. But if we can avoid them all the better. Smaller pages, faster downloads, and more scalable designs that adapt better to the user\u2019s font size preference. But how can we add a gradient background without an image?\n\nHere we\u2019ll look at the only property that is not as yet part of the CSS standard \u2013 Apple\u2019s gradient function for use anywhere you can use images with CSS (in this case backgrounds). In essence, this takes SVG gradients, and makes them available via CSS syntax.\n\nHere\u2019s what the property and its value looks like:\n\nbackground-image: -webkit-gradient(linear, left top, left bottom, from(#e9ede8), to(#ce401c),color-stop(0.4, #8c1b0b));\n\nZooming in on the gradient function, it has this basic form:\n\n-webkit-gradient(type, point, point, from(color), to(color),color-stop(where, color));\n\nWhich might look complicated, but is less so than at first glance.\n\nThe name of the function is gradient (and in this case, because it is an experimental property, we use the -webkit- prefix).\n\nYou might not have seen CSS functions before, but there are others, including the attr() function, used with generated content. A function returns a value that can be used as a property value \u2013 here we are using it as a background image.\n\nNext we specify the type of the gradient. Here we have a linear gradient, and there are also radial gradients. \n\nAfter that, we specify the start and end points of the gradient \u2013 in our case the top and bottom of the element, in a vertical line. \n\nWe then specify the start and end colors \u2013 and finally one stop color, located at 40% of the way down the element. Together, this creates a gradient that smoothly transitions from the start color in the top, vertically to the stop color, then smoothly transitions to the end color.\n\nThere\u2019s one last thing. What color will the background of our button be if the browser doesn\u2019t support gradients? It will be white (or possibly some default color for buttons). Which may make the text difficult or impossible to read. So, we\u2019ll add a background color as well (see why the validator is always warning you when a color but not a background color is specified for an element?).\n\nIf we put it all together, here\u2019s what we have:\n\nbutton {\n\twidth: 15em;\n\tpadding: .5em;\n\tcolor: #ffffff;\n\ttext-shadow: 1px 1px 1px #000;\n\tborder: solid thin #882d13;\n\t-webkit-border-radius: .7em;\n\t-moz-border-radius: .7em;\n\tborder-radius: .7em;\n\t-webkit-box-shadow: 2px 2px 3px #999; \n\tbox-shadow: 2px 2px 2px #bbb;\n\tbackground-color: #ce401c;\n\tbackground-image: -webkit-gradient(linear, left top, left bottom, from(#e9ede8), to(#ce401c),color-stop(0.4, #8c1b0b));\n}\n\nWhich looks like this in various browsers:\n\nIn Safari (3)\n\n\n\nIn Firefox 3.1 (3.0 supports border-radius but not text-shadow)\n\n\n\nIn Opera 10\n\n\n\nand of course in Internet Explorer (version 8 shown here)\n\n\n\nBut it looks different in different browsers\n\nYes, it does look different in different browsers, but we all know the answer to the question \u201cdo web sites need to look the same in every browser?\u201c.\n\nEven if you really think sites should look the same in every browser, hopefully this little tutorial has whet your appetite for what CSS3 and experimental CSS that\u2019s already supported in widely used browsers (and we haven\u2019t even touched on animations and similar effects!).\n\nI hope you\u2019ve enjoyed out little CSSMas present, and look forward to seeing your shiny buttons everywhere on the web.\n\nOh, and there\u2019s just a bit of homework \u2013 your job is to use the :hover selector, and make a gradient in the hover state.", "year": "2008", "author": "John Allsopp", "author_slug": "johnallsopp", "published": "2008-12-18T00:00:00+00:00", "url": "https://24ways.org/2008/shiny-happy-buttons/", "topic": "code"}
{"rowid": 42, "title": "An Overview of SVG Sprite Creation Techniques", "contents": "SVG can be used as an icon system to replace icon fonts. The reasons why SVG makes for a superior icon system are numerous, but we won\u2019t be going over them in this article. If you don\u2019t use SVG icons and are interested in knowing why you may want to use them, I recommend you check out \u201cInline SVG vs Icon Fonts\u201d by Chris Coyier \u2013 it covers the most important aspects of both systems and compares them with each other to help you make a better decision about which system to choose.\n\nOnce you\u2019ve made the decision to use SVG instead of icon fonts, you\u2019ll need to think of the best way to optimise the delivery of your icons, and ways to make the creation and use of icons faster.\n\nJust like bitmaps, we can create image sprites with SVG \u2013 they don\u2019t look or work exactly alike, but the basic concept is pretty much the same.\n\nThere are several ways to create SVG sprites, and this article will give you an overview of three of them. While we\u2019re at it, we\u2019re going to take a look at some of the available tools used to automate sprite creation and fallback for us.\n\nPrerequisites\n\nThe content of this article assumes you are familiar with SVG. If you\u2019ve never worked with SVG before, you may want to look at some of the introductory tutorials covering SVG syntax, structure and embedding techniques. I recommend the following:\n\n\n\tSVG basics: Using SVG.\n\tStructure: Structuring, Grouping, and Referencing in SVG  \u2014  The <g>, <use>, <defs> and <symbol> Elements. We\u2019ll mention <use> and <symbol> quite a bit in this article.\n\tEmbedding techniques: Styling and Animating SVGs with CSS. The article covers several topics, but the section linked focuses on embedding techniques.\n\tA compendium of SVG resources compiled by Chris Coyier  \u2014  contains resources to almost every aspect of SVG you might be interested in.\n\n\nAnd if you\u2019re completely new to the concept of spriting, Chris Coyier\u2019s CSS Sprites explains all about them.\n\nAnother important SVG feature is the viewBox attribute. For some of the techniques, knowing your way around this attribute is not required, but it\u2019s definitely more useful if you understand \u2013 even if just vaguely \u2013 how it works. The last technique mentioned in the article requires that you do know the attribute\u2019s syntax and how to use it. To learn all about viewBox, you can refer to my blog post about SVG coordinate systems.\n\nWith the prerequisites in place, let\u2019s move on to spriting SVGs!\n\nBefore you sprite\u2026\n\nIn order to create an SVG sprite with your icons, you\u2019ll of course need to have these icons ready for use.\n\nSome spriting tools require that you place your icons in a folder to which a certain spriting process is to be applied. As such, for all of the upcoming sections we\u2019ll work on the assumption that our SVG icons are placed in a folder named SVG.\n\nEach icon is an individual .svg file.\n\nYou\u2019ll need to make sure each icon is well-prepared and optimised for use \u2013 make sure you\u2019ve cleaned up the code by running it through one of the optimisation tools or processes available (or doing it manually if it\u2019s not tedious).\n\nAfter prepping the icon files and placing them in a folder, we\u2019re ready to create our SVG sprite.\n\nHTML inline SVG sprites\n\nSince SVG is XML code, it can be embedded inline in an HTML document as a code island using the <svg> element. Chris Coyier wrote about this technique first on CSS-Tricks.\n\nThe embedded SVG will serve as a container for our icons and is going to be the actual sprite we\u2019re going to use. So we\u2019ll start by including the SVG in our document.\n\n<!DOCTYPE html>\n<!-- HTML document stuff -->\n\n<svg style=\"display:none;\">\n  <!-- icons here -->\n</svg>\n\n<!-- other document stuff -->\n</html>\n\nNext, we\u2019re going to place the icons inside the <svg>. Each icon will be wrapped in a <symbol> element we can then reference and use elsewhere in the page using the SVG <use> element. The <symbol> element has many benefits, and we\u2019re using it because it allows us to define a symbol (which is a convenient markup for an icon) without rendering that symbol on the screen. The elements defined inside <symbol> will only be rendered when they are referenced \u2013 or called \u2013 by the <use> element.\n\nMoreover, <symbol> can have its own viewBox attribute, which makes it possible to control the positioning of its content inside its container at any time.\n\nBefore we move on, I\u2019d like to shed some light on the style=\"display:none;\" part of the snippet above. Without setting the display of the SVG to none, and even though its contents are not rendered on the page, the SVG will still take up space in the page, resulting in a big empty area. In order to avoid that, we\u2019re hiding the SVG entirely with CSS.\n\nNow, suppose we have a Twitter icon in the icons folder. twitter.svg might look something like this:\n\n<!-- twitter.svg -->\n<?xml version=\"1.0\" encoding=\"utf-8\"?>\n<!DOCTYPE svg PUBLIC \"-//W3C//DTD SVG 1.1//EN\" \"http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd\">\n<svg version=\"1.1\" xmlns=\"http://www.w3.org/2000/svg\" xmlns:xlink=\"http://www.w3.org/1999/xlink\" width=\"32\" height=\"32\" viewBox=\"0 0 32 32\">\n<path d=\"M32 6.076c-1.177 0.522-2.443 0.875-3.771 1.034 1.355-0.813 2.396-2.099 2.887-3.632-1.269 0.752-2.674 1.299-4.169 1.593-1.198-1.276-2.904-2.073-4.792-2.073-3.626 0-6.565 2.939-6.565 6.565 0 0.515 0.058 1.016 0.17 1.496-5.456-0.274-10.294-2.888-13.532-6.86-0.565 0.97-0.889 2.097-0.889 3.301 0 2.278 1.159 4.287 2.921 5.465-1.076-0.034-2.088-0.329-2.974-0.821-0.001 0.027-0.001 0.055-0.001 0.083 0 3.181 2.263 5.834 5.266 6.437-0.551 0.15-1.131 0.23-1.73 0.23-0.423 0-0.834-0.041-1.235-0.118 0.835 2.608 3.26 4.506 6.133 4.559-2.247 1.761-5.078 2.81-8.154 2.81-0.53 0-1.052-0.031-1.566-0.092 2.905 1.863 6.356 2.95 10.064 2.95 12.076 0 18.679-10.004 18.679-18.68 0-0.285-0.006-0.568-0.019-0.849 1.283-0.926 2.396-2.082 3.276-3.398z\" fill=\"#000000\"></path>\n</svg>\n\nWe don\u2019t need the root svg element, so we\u2019ll strip the code and only keep the parts that make up the Twitter icon\u2019s shape, which in this example is just the <path> element.Let\u2019s drop that into the sprite container like so:\n\n<svg style=\"display:none;\">\n  <symbol id=\"twitter-icon\" viewBox=\"0 0 32 32\">\n    <path d=\"M32 6.076c-1.177 \u2026\" fill=\"#000000\"></path>\n  </symbol>\n\n <!-- remaining icons here -->\n  <symbol id=\"instagram-icon\" viewBox=\"0 0 32 32\">\n   <!-- icon contents -->\n  </symbol>\n\n  <!-- etc. -->\n</svg>\n\nRepeat for the other icons.\n\nThe value of the <symbol> element\u2019s viewBox attribute depends on the size of the SVG. You don\u2019t need to know how the viewBox works to use it in this case. Its value is made up of four parts: the first two will almost always be \u201c0 0\u201d; the second two will be equal to the size of the icon. For example, our Twitter icon is 32px by 32px (see twitter.svg above), so the viewBox value is \u201c0 0 32 32\u201d.\n\nThat said, it is certainly useful to understand how the viewBox works \u2013 it can help you troubleshoot SVG sometimes and gives you better control over it, allowing you to scale, position and even crop SVGs manually without having to resort to an editor. My blog post explains all about the viewBox attribute and its related attributes.\n\nOnce you have your SVG sprite ready, you can display the icons anywhere on the page by referencing them using the SVG <use> element:\n\n<svg class=\"twitter-icon\">\n  <use xlink:href=\"#twitter-icon\"></use>\n<svg>\n\nAnd that\u2019s all there is to it!\n\nHTML-inline SVG sprites are simple to create and use, but when you have a lot of icons (and the more icon sets you create) it can easily become daunting if you have to manually transfer the icons into the <svg>. Fortunately, you don\u2019t have to do that. Fabrice Weinberg created a Grunt plugin called grunt-svgstore which takes the icons in your SVG folder and generates the SVG sprites for you; all you have to do is just drop the sprites into your page and use the icons like we did earlier.\n\nThis technique works in all browsers supporting SVG. There seems to be a bug in Safari on iOS which causes the icons not to show up when the SVG sprite is defined at the bottom of the document after the <use> references to the icons, so it\u2019s safest to include the sprite before you use the icons until this bug is fixed.\n\nThis technique has one disadvantage: the SVG sprite cannot be cached. We\u2019re saving an extra HTTP request here but the browser cannot cache the image, so we aren\u2019t speeding up any subsequent page loads by inlining the SVG. There must be a better way \u2013 and there is.\n\nStyling the icons is possible, but getting deep into the styles becomes a bit harder owing to the nature of the contents of the <use> element \u2013 these contents are cloned into a shadow DOM, and hence selecting elements in CSS the traditional way is not possible. However, some techniques to work around that do exist, and give us slightly more styling flexibility. Animations work as expected.\n\nReferencing an external SVG sprite in HTML\n\nInstead of including the SVG inline in the document, you can reference the sprite and the icons inside it externally, taking advantage of fragment identifiers to select individual icons in the sprite.\n\nFor example, the above reference to the Twitter icon would look something like this instead:\n\n<svg class=\"twitter-icon\">\n  <use xlink:href=\"path/to/icons.svg#twitter-icon\"></use>\n<svg>\n\n\nicons.svg is the name of the SVG file that contains all of our icons as symbols, and the fragment identifier #twitter-icon is the reference to the <symbol> wrapping the Twitter icon\u2019s contents. Very convenient, isn\u2019t it? The browser will request the sprite and then cache it, speeding up subsequent page loads. Win!\n\nThis technique also works in all browsers supporting SVG except Internet Explorer \u2013 not even IE9+ with SVG support permits this technique. No version of IE supports referencing an external SVG in <use>.\n\nFortunately (again), Jonathan Neil has created a plugin called svg4everybody which fills this gap in IE; you can reference an external sprite in <use> and also provide fallback for browsers that do not support SVG. However, it requires you to have the fallback images (PNG or JPEG, for example) available to do so. For details, refer to the plugin\u2019s Github repository\u2019s readme file.\n\nCSS inline SVG sprites\n\nAnother way to create an SVG sprite is by inlining the SVG icons in a style sheet using data URIs, and providing fallback for non-supporting browsers \u2013 also within the CSS.\n\nUsing this approach, we\u2019re turning the style sheet into the sprite that includes our icons. The style sheet is normally cached by the browser, so we have that concern out of the way.\n\nThis technique is put into practice in Filament Group\u2019s icon system approach, which uses their Grunticon plugin \u2013 or its sister Grumpicon web app \u2013 for generating the necessary CSS for the sprite. As such, we\u2019re going to cover this technique by following a workflow that uses one of these tools.\n\nAgain, we start with our icon SVG files. To focus on the actual spriting method and not on the tooling, I\u2019ll go over the process of sprite creation using the Grumpicon web app, instead of the Grunticon plugin. Both tools generate the same resources that we\u2019re going to use for the icon system. Whether you choose the web app or the Grunt set-up, after processing your SVG folder you\u2019re going to end up with the same set of resources that we\u2019ll be using throughout this section.\n\nThe first step is to drop your icons into the Grumpicon web app.\n\n Grumpicon homepage screenshot.\n\nThe application will then show you a preview of your icons, and a download button will allow you to download the generated files. These files will contain everything you need for your icon system \u2013 all that\u2019s left is for you to drop the generated files and code into your project as recommended and you\u2019ll have your sprite and icons ready to use anywhere you want in your page.\n\nGrumpicon generates five files and one folder in the downloaded package: a png folder containing PNG versions of your icons; three style sheets (that we\u2019ll go over briefly); a loader script file; and preview.html which is a live example showing you the other files in action.\n\nThe script in the loader goes into the <head> of your page. This script handles browser and feature detection, and requests the necessary style sheet depending on browser support for SVG and base64 data URIs. If you view the source code of the preview page, you can see exactly how the script is added.\n\nicons.data.svg.css is the style sheet that contains your icons \u2013 the sprite. The icons are embedded inline inside the style sheet using data URIs, and applied to elements of your choice as background images, using class names. For example:\n\n.twitter-icon{\n    background-image: url('data:image/svg+xml;\u2026'); /* the ellipsis is where the icon\u2019s data would go */\n    background-repeat: no-repeat;\n    background-position: 50% 50%;\n    height: 2em;\n    width: 2em;\n    /* etc. */\n}\n\nThen, you only have to apply the twitter-icon class name to an element in your HTML to apply the icon as a background to it:\n\n<span class=\"twitter-icon\"></span>\n\nAnd that\u2019s all you need to do to get an icon on the page.\n\nicons.data.svg.css, along with the other two style sheets and the png folder should be added to your CSS folder.\n\nicons.data.png.css is the style sheet the script will load in browsers that don\u2019t support SVG, such as IE8. Fallback for the inline SVG is provided as a base64-encoded PNG. For instance, the fallback for the Twitter icon from our example would look like so:\n\n.twitter-icon{\n    background-image: url('data:image/png;base64;\u2026\u2019);\n    /* etc. */\n}\n\nicons.fallback.css is the style sheet required for browsers that don\u2019t support base64-encoded PNGs \u2013 the PNG images are loaded as usual using the image\u2019s URL. The script will load this style sheet for IE6 and IE7, for example.\n\n.twitter-icon{\n    background-image: url(png/twitter-icon.png);\n    /* etc. */\n}\n\nThis technique is very different from the previous one. The sprite in this case is literally the style sheet, not an SVG container, and the icon usage is very similar to that of a CSS sprite \u2013 the icons are provided as background images.\n\nThis technique has advantages and disadvantages. For the sake of brevity, I won\u2019t go into further details, but the main limitations worth mentioning are that SVGs embedded as background images cannot be styled with CSS; and animations are restricted to those defined inside the <svg> for each icon. CSS interactions (such as hover effects) don\u2019t work either. Thus, to apply an effect for an icon that changes its color on hover, for example, you\u2019ll need to export a set of SVGs for each colour in order for Grumpicon to create matching fallback PNG images that can then be used for the animation.\n\nFor more details about the Grumpicon workflow, I recommend you check out \u201cA Designer\u2019s Guide to Grumpicon\u201d on Filament Group\u2019s website.\n\nUsing SVG fragment identifiers and views\n\nThis spriting technique is, again, different from the previous ones, and it is my personal favourite.\n\nSVG comes with a standard way of cropping to a specific area in a particular SVG image. If you\u2019ve ever worked with CSS sprites before then this definitely sounds familiar: it\u2019s almost exactly what we do with CSS sprites \u2013 the image containing all of the icons is cropped, so to speak, to show only the one icon that we want in the background positioning area of the element, using background size and positioning properties.\n\nInstead of using background properties, we\u2019ll be using SVG\u2019s viewBox attribute to crop our SVG to the specific icon we want.\n\nWhat I like about this technique is that it is more visual than the previous ones. Using this technique, the SVG sprite is treated like an actual image containing other images (the icons), instead of treating it as a piece of code containing other code.\n\nAgain, our SVG icons are placed inside a main SVG container that is going to be our SVG sprite. If you\u2019re working in a graphics editor, position or arrange your icons inside the canvas any way you want them to be, and then export the graphic as is. Of course, the less empty space there is in your SVG, the better.\n\nIn our example, the sprite contains three icons as shown in the following image. The sprite is open in Sketch. Notice how the SVG is just big enough to fit the icons inside it. It doesn\u2019t have to be like this, but it\u2019s cleaner this way.\n\n Screenshot showing the SVG sprite containing our icons.\n\nNow, suppose you want to display only the Instagram icon. Using the SVG viewBox attribute, we can crop the SVG to the icon. The Instagram icon is positioned at 64px along the positive x-axis, and zero pixels along the y-axis. It is also 32px by 32px in size.\n\n Screenshot showing the position (offset) of the Instagram icon inside the SVG sprite, and its size.\n\nUsing this information, we can specify the value of the viewBox as: 64 0 32 32. This area of the view box contains only the Instagram icon. 64 0 specifies the top-left corner of the view box area, and 32 32 specify its dimensions.\n\nNow, if we were to change the viewBox value on the SVG sprite to this value, only the Instagram icon will be visible inside the SVG viewport. Great. But how do we use this information to display the icon in our page using our sprite?\n\nSVG comes with a native way to link to portions or areas of an image using fragment identifiers. Fragment identifiers are used to link into a particular view area of an SVG document. Thus, using a fragment identifier and the boundaries of the area that we want (from the viewBox), we can link to that area and display it.\n\nFor example, if you want to display the icon from the sprite using an <img> tag, you can reference the icon in the sprite like so:\n\n<img src='uiIcons.svg#svgView(viewBox(64, 0, 32, 32))' alt=\"Settings icon\"/>\n\nThe fragment identifier in the snippet above (#svgView(viewBox(64, 0, 32, 32))) is the important part. This will result in only the Instagram icon\u2019s area of the sprite being displayed.\n\nThere is also another way to do this, using the SVG <view> element. The <view> element can be used to define a view area and then reference that area somewhere else. For example, to define the view box containing the Instagram icon, we can do the following:\n\n<view id='instagram-icon' viewBox='64 0 32 32' />\n\nThen, we can reference this view in our <img> element like this:\n\n<img src='sprite.svg#instagram-icon' alt=\"Instagram icon\" />\n\nThe best part about this technique \u2013 besides the ability to reference an external SVG and hence make use of browser caching \u2013 is that it allows us to use practically any SVG embedding technique and does not restrict us to specific tags.\n\nIt goes without saying that this feature can be used for more than just icon systems, owing to viewBox\u2019s power in controlling an SVG\u2019s viewable area.\n\nSVG fragment identifiers have decent browser support, but the technique is buggy in Safari: there is a bug that causes problems when loading a server SVG file and then using fragment identifiers with it. Bear Travis has documented the issue and a workaround.\n\nWhere to go from here\n\nPick the technique that works best for your project. Each technique has its own pros and cons, relating to convenience and maintainability, performance, and styling and scripting. Each technique also requires its own fallback mechanism.\n\nThe spriting techniques mentioned here are not the only techniques available. Other methods exist, such as SVG stacks, and others may surface in future, but these are the three main ones today.\n\nThe third technique using SVG\u2019s built-in viewBox features is my favourite, and with better browser support and fewer (ideally, no) bugs, I believe it is more likely to become the standard way to create and use SVG sprites. Fallback techniques can be created, of course, in one of many possible ways.\n\nDo you use SVG for your icon system? If so, which is your favourite technique?

{"rowid": 3, "title": "Project Hubs: A Home Base for Design Projects", "contents": "SCENE: A design review meeting. Laptop screens. Coffee cups.\n\nProject manager: Hey, did you get my email with the assets we\u2019ll be discussing? \n\nClient: I got an email from you, but it looks like there\u2019s no attachment.\n\nPM: Whoops! OK. I\u2019m resending the files with the attachments. Check again?\n\nClient: OK, I see them. It\u2019s homepage_v3_brian-edits_FINAL_for-review.pdf, right? \n\nPM: Yeah, that\u2019s the one.\n\nClient: OK, hang on, Bill\u2019s going to print them out. (3-minute pause. Small talk ensues.)\n\nClient: Alright, Bill\u2019s back. We\u2019re good to start. \n\nBrian: Oh, actually those homepage edits we talked about last time are in the homepage_v4_brian_FINAL_v2.pdf document that I posted to Basecamp earlier today.\n\nClient: Oh, OK. What message thread was that in? \n\nBrian: Uh, I\u2019m pretty sure it\u2019s in \u201cHomepage Edits and Holiday Schedule.\u201d\n\nClient: Alright, I see them. Bill\u2019s going back to the printer. Hang on a sec\u2026\n\n\n\nThis is only a slightly exaggerated version of my experience in design review meetings. \n\nThe design project dance is a sloppy one. It involves a slew of email attachments, PDFs, PSDs, revisions, GitHub repos, staging environments, and more. And while tools like Basecamp can help manage all these moving parts, it can still be incredibly challenging to extract only the important bits, juggle deliverables, and see how your project is progressing.\n\nEnter project hubs. \n\nProject hubs\n\nA project hub consolidates all the key design and development materials onto a single webpage presented in reverse chronological order. The timeline lives online (either publicly available or password protected), so that everyone involved in the team has easy access to it.\n\n A project hub.\n\nI was introduced to project hubs after seeing Dan Mall\u2019s open redesign of Reading Is Fundamental. Thankfully, I had a chance to work with Dan on two projects where I got to see firsthand how beneficial a project hub can be. Here\u2019s what makes a project hub great:\n\n\n\tServes as a centralized home base for the project\n\tTrains clients and teams to decide in the browser\n\tEasily and visually view project\u2019s progress\n\tProvides an archive for project artifacts\n\n\nA home base\n\nYour clients and colleagues can expect to get the latest and greatest updates to your project when visiting the project hub, the same way you\u2019d expect to get the latest information on a requested topic when you visit a Wikipedia page. That\u2019s the beauty of URIs that don\u2019t change. \n\nCreating a project hub reduces a ton of email volley nonsense, and eliminates the need to produce files and directories with staggeringly ridiculous names like design/12.13.13/team/brian/for_review/_FINAL/styletile_121313_brian-edits-final_v2_FINAL.pdf. The team can simply visit the project hub\u2019s URL and click the link to whatever artifact they need. Need to make an update? Simply update the link on the project hub. No more email tango and silly file names. \n\nDeciding in the browser\n\n\n\tLet\u2019s change the phrase \u201cdesigning in the browser\u201d to \u201cdeciding in the browser.\u201d\nDan Mall\n\n\nWe make websites, but all too often we find ourselves looking at web design artifacts in abstractions. We email PDFs to each other, glance at mockup JPGs on our desktops, and of course kill trees in order to print out designs so that we can scribble in the margins. All of these practices subtly take everyone further and further away from the design\u2019s eventual final resting place: the browser.\n\nBecause a project hub is just a simple webpage, reviewing designs is as easy as clicking some links, which keep your clients and teams in the browser. \n\nYou can keep people in the browser with yet another clever trick from the wily Dan Mall: instead of sending clients PDFs or JPGs, he created a simple webpage and tossed his static visuals into the template (you can view an example here). This forces clients to review web design work in the browser rather than launching a PDF viewer or Preview. \n\nNow this all might sound trivial to you (\u201cOf course my client knows that we\u2019re designing a website!\u201d), but keeping the design artifacts in the browser subconsciously helps remind everyone of the medium for which you\u2019re designing, which helps everyone focus on the right aspects of the design and have the right conversations. \n\nProgress over time\n\nWhen you\u2019re in the trenches, it\u2019s often hard to visualize how a project is progressing. Tools like Basecamp include discussions, files, to-dos, and more, which are all great tools but also make things a bit noisy. Project hubs provide you and your clients a quick and easy way to see at a glance how things are coming along. Teams can rest assured they\u2019re viewing the most current versions of designs, and managers can share progress with stakeholders simply by providing a link to the project hub. \n\nOver time, a project hub becomes an easily accessible archive of all the design decisions, which makes it easy to compare and contrast different versions of designs and prototypes.\n\nSetting up a project hub\n\nSetting up your own project hub is pretty simple. Simply create a webpage with some basic styles and branding. I\u2019ve created a project hub template that\u2019s available on GitHub if you want a jump-start.\n\nPublish the webpage to a URL somewhere that makes sense (we\u2019ve found that a subdomain of your site works quite well) and share it with everyone involved in the project. Bookmark it. Let everyone know that this is where design updates will be shared, and that they can always come back to the project hub to track the project\u2019s progress.\n\nWhen it comes time to share new updates, simply add a new node to the timeline and republish the webpage. Simple FTPing works just fine, but it might make sense to keep track of changes using version control. Our project hub for our open redesign of the Pittsburgh Food Bank is managed on GitHub, which means that I can make edits to the hub right from GitHub. Thanks to the magical wizardry of webhooks, I can automatically deploy the project hub so that everything stays in sync. That\u2019s the fancy-pants way to do it, and is certainly not a requirement. As long as you\u2019re able to easily make edits and keep your project hub up to date, you\u2019re good to go. \n\nSo that\u2019s the hubbub\n\nProject hubs can help tame the chaos of the design process by providing a home base for all key design and development materials. Keep the design artifacts in the browser and give clients and colleagues quick insight into your project\u2019s progress.\n\nHappy hubbing!", "year": "2013", "author": "Brad Frost", "author_slug": "bradfrost", "published": "2013-12-17T00:00:00+00:00", "url": "https://24ways.org/2013/project-hubs/", "topic": "process"}
{"rowid": 263, "title": "Securing Your Site like It\u2019s 1999", "contents": "Running a website in the early years of the web was a scary business. The web was an evolving medium, and people were finding new uses for it almost every day. From book stores to online auctions, the web was an expanding universe of new possibilities.\nAs the web evolved, so too did the knowledge of its inherent security vulnerabilities. Clever tricks that were played on one site could be copied on literally hundreds of other sites. It was a normal sight to log in to a website to find nothing working because someone had breached its defences and deleted its database. Lessons in web security in those days were hard-earned.\nWhat follows are examples of critical mistakes that brought down several early websites, and how you can help protect yourself and your team from the same fate.\nBad input validation: Trusting anything the user sends you\nOur story begins in the most unlikely place: Animal Crossing. Animal Crossing was a 2001 video game set in a quaint town, filled with happy-go-lucky inhabitants that co-exist peacefully. Like most video games, Animal Crossing was the subject of many fan communities on the early web.\nOne such unofficial web forum was dedicated to players discussing their adventures in Animal Crossing. Players could trade secrets, ask for help, and share pictures of their virtual homes. This might sound like a model community to you, but you would be wrong.\nOne day, a player discovered a hidden field in the forum\u2019s user profile form. Normally, this page allows users to change their name, their password, or their profile photo. This person discovered that the hidden field contained their unique user ID, which identifies them when the forum\u2019s backend saves profile changes to its database. They discovered that by modifying the form to change the user ID, they could make changes to any other player\u2019s profile.\nNeedless to say, this idyllic online community descended into chaos. Users changed each other\u2019s passwords, deleted each other\u2019s messages, and attacked each-other under the cover of complete anonymity. What happened?\nThere aren\u2019t any official rules for developing software on the web. But if there were, my golden rule would be:\nNever trust user input. Ever.\nAlways ask yourself how users will send you data that isn\u2019t what it seems to be. If the nicest community of gamers playing the happiest game on earth can turn on each other, nowhere on the web is safe.\nMake sure you validate user input to make sure it\u2019s of the correct type (e.g. string, number, JSON string) and that it\u2019s the length that you were expecting. Don\u2019t forget that user input doesn\u2019t become safe once it is stored in your database; any data that originates from outside your network can still be dangerous and must be escaped before it is inserted into HTML.\nMake sure to check a user\u2019s actions against what they are allowed to do. Create a clear access control policy that defines what actions a user may take, and to whose data they are allowed access to. For example, a newly-registered user should not be allowed to change the user profile of a web forum\u2019s owner.\nFinally, never rely on client-side validation. Validating user input in the browser is a convenience to the user, not a security measure. Always assume the user has full control over any data sent from the browser and make sure you validate any data sent to your backend from the outside world.\nSQL injection: Allowing the user to run their own database queries\nA long time ago, my favourite website was a web forum dedicated to the Final Fantasy video game series. Like the users of the Animal Crossing forum, I\u2019d while away many hours arguing with other people on the internet about my favourite characters, my favourite stories, and the greatest controversies of the day.\nOne day, I noticed people were acting strangely. Users were being uncharacteristically nasty and posting in private areas of the forum they wouldn\u2019t normally have access to. Then messages started disappearing, and user accounts for well-respected people were banned.\nIt turns out someone had discovered a way of logging in to any other user account, using a secret password that allowed them to do literally anything they wanted. What was this password that granted untold power to those who wielded it?\n' OR '1'='1\nSQL is a computer language that is used to query databases. When you fill out a login form, just like the one above, your username and your password are usually inserted into an SQL query like this:\n\nSELECT COUNT(*)\nFROM USERS\nWHERE USERNAME='Alice'\nAND PASSWORD='hunter2'\nThis query selects users from the database that match the username Alice and the password hunter2. If there is at least one user matching record, the user will be granted access. Let\u2019s see what happens when we use our magic password instead!\n\nSELECT COUNT(*)\nFROM USERS\nWHERE USERNAME='Admin'\nAND PASSWORD='' OR '1'='1'\nDoes the password look like part of the query to you? That\u2019s because it is! This password is a deliberate attempt to inject our own SQL into the query, hence the term SQL injection. The query is now looking for users matching the username Admin, with a password that is blank, or 1=1. In an SQL query, 1=1 is always true, which makes this query select every single record in the database. As long as the forum software is checking for at least one matching user, it will grant the person logging in access. This password will work for any user registered on the forum!\nSo how can you protect yourself from SQL injection?\nNever build SQL queries by concatenating strings. Instead, use parameterised query tools. PHP offers prepared statements, and Node.JS has the knex package. Alternatively, you can use an ORM tool, such as Propel or sequelize.\nExpert help in the form of language features or software tools is a key ally for securing your code. Get all the help you can!\nCross site request forgery: Getting other users to do your dirty work for you\nDo you remember Netflix? Not the Netflix we have now, the Netflix that used to rent you DVDs by mailing them to you. My next story is about how someone managed to convince Netflix users to send him their DVDs - free of charge.\nHave you ever clicked on a hyperlink, only to find something that you weren\u2019t expecting? If you were lucky, you might have just gotten Rickrolled. If you were unlucky\u2026\nLet\u2019s just say there are older and fouler things than Rick Astley in the dark places of the web.\nWhat if you could convince people to visit a page you controlled? And what if those people were Netflix users, and they were logged in? In 2006, Dave Ferguson did just that. He created a harmless-looking page with an image on it:\n<img src=\"http://www.netflix.com/JSON/AddToQueue?movieid=70110672\" />\nDid you notice the source URL of the image? It\u2019s deliberately crafted to add a particular DVD to your queue. Sprinkle in a few more requests to change the user\u2019s name and shipping address, and you could ship yourself DVDs completely free of charge!\nThis attack is possible when websites unconditionally trust a user\u2019s session cookies without checking where HTTP requests come from.\nThe first check you can make is to verify that a request\u2019s origin and referer headers match the location of the website. These headers can\u2019t be programmatically set.\nAnother check you can use is to add CSRF tokens to your web forms, to verify requests have come from an actual form on your website. Tokens are long, unpredictable, unique strings that are generated by your server and inserted into web forms. When users complete a form, the form data sent to the server can be checked for a recently generated token. This is an effective deterrent of CSRF attacks because CSRF tokens aren\u2019t stored in cookies.\nYou can also set SameSite=Strict when setting cookies with the Set-Cookie HTTP header. This communicates to browsers that cookies are not to be sent with cross-site requests. This is a relatively new feature, though it is well supported in evergreen browsers.\nCross site scripting: Someone else\u2019s code running on your website\nIn 2005, Samy Kamkar became famous for having lots of friends. Lots and lots of friends.\nSamy enjoyed using MySpace which, at the time, was the world\u2019s largest social network. Social networks at that time were more limited than today. For instance, MySpace let you upload photos to your photo gallery, but capped the limit at twelve. Twelve photos. At least you didn\u2019t have to wade through photos of avocado toast back then\u2026\nSamy discovered that MySpace also locked down the kinds of content that you could post on your MySpace page. He discovered he could inject <img /> and <div /> tags into his headline, but <script /> was filtered. MySpace wasn\u2019t about to let someone else run their own code on MySpace.\nIntrigued, Samy set about finding out exactly what he could do with <img /> and <div /> tags. He found that you could add style properties to <div /> tags to style them with CSS.\n<div style=\"background:url('javascript:alert(1)')\">\nThis code only worked in Internet Explorer and in some versions of Safari, but that was plenty of people to befriend. However, MySpace was prepared for this: they also filtered the word javascript from <div />.\n<div style=\"background:url('java\nscript:alert(1)')\">\nSamy discovered that by inserting a line break into his code, MySpace would not filter out the word javascript. The browser would continue to run the code just fine! Samy had now broken past MySpace\u2019s first line of defence and was able to start running code on his profile page. Now he started looking at what he could do with that code.\nalert(document.body.innerHTML)\nSamy wondered if he could inspect the page\u2019s source to find the details of other MySpace users to befriend. To do this, you would normally use document.body.innerHTML, but MySpace had filtered this too.\nalert(eval('document.body.inne' + 'rHTML'))\nThis isn\u2019t a problem if you build up JavaScript code inside a string and execute it using the eval() function. This trick also worked with XMLHttpRequest.onReadyStateChange, which allowed Samy to send friend requests to the MySpace API and install the JavaScript code on his new friends\u2019 pages.\nOne final obstacle stood in his way. The same origin policy is a security mechanism that prevents scripts hosted on one domain interacting with sites hosted on another domain.\nif (location.hostname == 'profile.myspace.com') {\n  document.location = 'http://www.myspace.com'\n  + location.pathname + location.search\n}\nSamy discovered that only the http://www.myspace.com domain would accept his API requests, and requests from http://profile.myspace.com were being blocked by the browser\u2019s same-origin policy. By redirecting the browser to http://www.myspace.com, he discovered that he could load profile pages and successfully make requests to MySpace\u2019s API. Samy installed this code on his profile page, and he waited.\n\nOver the course of the next day, over a million people unwittingly installed Samy\u2019s code into their MySpace profile pages and invited their friends. The load of friend requests on MySpace was so large that the site buckled and shut down. It took them two hours to remove Samy\u2019s code and patch the security holes he exploited. Samy was raided by the United States secret service and sentenced to do 90 days of community service.\nThis is the power of installing a little bit of JavaScript on someone else\u2019s website. It is called cross site scripting, and its effects can be devastating. It is suspected that cross-site scripting was to blame for the 2018 British Airways breach that leaked the credit card details of 380,000 people.\nSo how can you help protect yourself from cross-site scripting?\nAlways sanitise user input when it comes in, using a library such as sanitize-html. Open source tools like this benefit from hundreds of hours of work from dozens of experienced contributors. Don\u2019t be tempted to roll your own protection. MySpace was prepared, but they were not prepared enough. It makes no sense to turn this kind of help down.\nYou can also use an auto-escaping templating language to make sure nobody else\u2019s HTML can get into your pages. Both Angular and React will do this for you, and they are extremely convenient to use.\nYou should also implement a content security policy to restrict the domains that content like scripts and stylesheets can be loaded from. Loading content from sites not under your control is a significant security risk, and you should use a CSP to lock this down to only the sources you trust. CSP can also block the use of the eval() function.\nFor content not under your control, consider setting up sub-resource integrity protection. This allows you to add hashes to stylesheets and scripts you include on your website. Hashes are like fingerprints for digital files; if the content changes, so does the fingerprint. Adding hashes will allow your browser to keep your site safe if the content changes without you knowing.\nnpm audit: Protecting yourself from code you don\u2019t own\nJavaScript and npm run the modern web. Together, they make it easy to take advantage of the world\u2019s largest public registry of open source software. How do you protect yourself from code written by someone you\u2019ve never met? Enter npm audit.\nnpm audit reviews the security of your website\u2019s dependency tree. You can start using it by upgrading to the latest version of npm:\nnpm install npm -g\nnpm audit\nWhen you run npm audit, npm submits a description of your dependencies to the Registry, which returns a report of known vulnerabilities for the packages you have installed.\n\nIf your website has a known cross-site scripting vulnerability, npm audit will tell you about it. What\u2019s more, if the vulnerability has been patched, running npm audit fix will automatically install the patched package for you!\nSecuring your site like it\u2019s 2019\nThe truth is that since the early days of the web, the stakes of a security breach have become much, much higher. The web is so much more than fandom and mailing DVDs - online banking is now mainstream, social media and dating websites store intimate information about our personal lives, and we are even inviting the internet into our homes.\nHowever, we have powerful new allies helping us stay safe. There are more resources than ever before to teach us how to write secure code. Tools like Angular and React are designed with security features baked-in from the start. We have a new generation of security tools like npm audit to watch over our dependencies.\nAs we roll over into 2019, let\u2019s take the opportunity to reflect on the security of the code we write and be grateful for the everything we\u2019ve learned in the last twenty years.", "year": "2018", "author": "Katie Fenn", "author_slug": "katiefenn", "published": "2018-12-01T00:00:00+00:00", "url": "https://24ways.org/2018/securing-your-site-like-its-1999/", "topic": "code"}
{"rowid": 92, "title": "Redesigning the Media Query", "contents": "Responsive web design is showing us that designing content is more important than designing containers. But if you\u2019ve given RWD a serious try, you know that shifting your focus from the container is surprisingly hard to do. There are many factors and\ninstincts working against you, and one culprit is a perpetrator you\u2019d least suspect.\n\nThe media query is the ringmaster of responsive design. It lets us establish the rules of the game and gives us what we need most: control. However, like some kind of evil double agent, the media query is actually working against you.\n\nIts very nature diverts your attention away from content and forces you to focus on the container.\n\nThe very act of choosing a media query value means choosing a screen size.\n\nLook at the history of the media query\u2014it\u2019s always been about the container. Values like screen, print, handheld and tv don\u2019t have anything to do with content. The modern media query lets us choose screen dimensions, which is great because it makes RWD possible. But it\u2019s still the act of choosing something that is completely unpredictable.\n\nContent should dictate our breakpoints, not the container. In order to get our focus back to the only thing that matters, we need a reengineered media query\u2014one that frees us from thinking about screen dimensions. A media query that works for your content, not the window. Fortunately, Sass 3.2 is ready and willing to take on this challenge.\n\nThinking in Columns\n\nFluid grids never clicked for me. I feel so disoriented and confused by their squishiness. Responsive design demands their use though, right?\n\nI was ready to surrender until I found a grid that turned my world upright again. The Frameless Grid by Joni Korpi demonstrates that column and gutter sizes can stay fixed. As the screen size changes, you simply add or remove columns to accommodate. This made sense to me and armed with this concept I was able to give Sass the first component it needs to rewrite the media query: fixed column and gutter size variables.\n\n$grid-column: 60px;\n$grid-gutter: 20px;\n\nWe\u2019re going to want some resolution independence too, so let\u2019s create a function that converts those nasty pixel values into ems.\n\n@function em($px, $base: $base-font-size) {\n\t@return ($px / $base) * 1em;\n}\n\nWe now have the components needed to figure out the width of multiple columns in ems. Let\u2019s put them together in a function that will take any number of columns and return the fixed width value of their size.\n\n@function fixed($col) {\n\t@return $col * em($grid-column + $grid-gutter)\n}\n\nWith the math in place we can now write a mixin that takes a column count as a parameter, then generates the perfect media query necessary to fit that number of columns on the screen. We can also build in some left and right margin for our layout by adding an additional gutter value (remembering that we already have one gutter built into our fixed function).\n\n@mixin breakpoint($min) {\n\t@media (min-width: fixed($min) + em($grid-gutter)) {\n\t\t@content\n\t}\n}\n\nAnd, just like that, we\u2019ve rewritten the media query. Instead of picking a minimum screen size for our layout, we can simply determine the number of columns needed. Let\u2019s add a wrapper class so that we can center our content on the screen.\n\n@mixin breakpoint($min) {\n    @media (min-width: fixed($min) + em($grid-gutter)) {\n\t.wrapper {\n\t\twidth: fixed($min) - em($grid-gutter);\n\t\tmargin-left: auto; margin-right: auto;\n\t}\n\t@content\n    }\n}\n\nDesigning content with a column count gives us nice, easy, whole numbers to work with. Sizing content, sidebars or widgets is now as simple as specifying a single-digit number.\n\n@include breakpoint(8) {\n\t.main { width: fixed(5); }\n\t.sidebar { width: fixed(3); }\n}\n\nThose four lines of Sass just created a responsive layout for us. When the screen is big enough to fit eight columns, it will trigger a fixed width layout. And give widths to our main content and sidebar. The following is the outputted CSS\u2026\n\n@media (min-width: 41.25em) {\n  .wrapper {\n    width: 38.75em;\n    margin-left: auto; margin-right: auto;\n  }\n  .main { width: 25em; }\n  .sidebar { width: 15em; }\n}\n\nDemo\n\nI\u2019ve created a Codepen demo that demonstrates what we\u2019ve covered so far. I\u2019ve added to the demo some grid classes based on Griddle by Nicolas Gallagher to create a floatless layout. I\u2019ve also added a CSS gradient overlay to help you visualize columns. Try changing the column variable sizes or the breakpoint includes to see how the layout reacts to different screen sizes.\n\nResponsive Images\n\nResponsive images are a serious problem, but I\u2019m excited to see the community talk so passionately about a solution. Now, there are some excellent stopgaps while we wait for something official, but these solutions require you to mirror your breakpoints in JavaScript or HTML. This poses a serious problem for my Sass-generated media queries, because I have no idea what the real values of my breakpoints are anymore. For responsive images to work, JavaScript needs to recognize which media query is active so that proper images can be loaded for that layout.\n\nWhat I need is a way to label my breakpoints. Fortunately, people much smarter than I have figured this out. Jeremy Keith devised a labeling method by using CSS-generated content as the storage method for breakpoint labels. We can use this technique in our breakpoint mixin by passing a label as another argument.\n\n@include breakpoint(8, 'desktop') { /* styles */ }\n\nSass can take that label and use it when writing the corresponding media query. We just need to slightly modify our breakpoint mixin.\n\n@mixin breakpoint($min, $label) {\n    @media (min-width: fixed($min) + em($grid-gutter)) {\n\n        // label our mq with CSS generated content\n\tbody::before { content: $label; display: none; }\n\n\t.wrapper {\n\t\twidth: fixed($min) - em($grid-gutter);\n\t\tmargin-left: auto; margin-right: auto;\n\t}\n\t@content\n    }\n}\n\nThis allows us to label our breakpoints with a user-friendly string. Now that our media queries are defined and labeled, we just need JavaScript to step in and read which label is active.\n\n// get css generated label for active media query\nvar label = getComputedStyle(document.body, '::before')['content'];\n\nJavaScript now knows which layout is active by reading the label in the current media query\u2014we just need to match that label to an image. I prefer to store references to different image sizes as data attributes on my image tag.\n\n<img class=\"responsive-image\" data-mobile=\"mobile.jpg\" data-desktop=\"desktop.jpg\" />\n<noscript><img src=\"desktop.jpg\" /></noscript>\n\nThese data attributes have names that match the labels set in my CSS. So while there is some duplication going on, setting a keyword like \u2018tablet\u2019 in two places is much easier than hardcoding media query values. With matching labels in CSS and HTML our script can marry the two and load the right sized image for our layout.\n\n// get css generated label for active media query\nvar label = getComputedStyle(document.body, '::before')['content'];\n\n// select image\nvar $image = $('.responsive-image');\n\n// create source from data attribute\n$image.attr('src', $image.data(label));\n\nDemo\n\nWith some slight additions to our previous Codepen demo you can see this responsive image technique in action. While the above JavaScript will work it is not nearly robust enough for production so the demo uses a jQuery plugin that can accomodate multiple images, reloading on screen resize and fallbacks if something doesn\u2019t match up.\n\nCreating a Framework\n\nThis media query mixin and responsive image JavaScript are the center piece of a front end framework I use to develop websites. It\u2019s a fluid, mobile first foundation that uses the breakpoint mixin to structure fixed width layouts for tablet and desktop. Significant effort was focused on making this framework completely cross-browser. For example, one of the problems with using media queries is that essential desktop structure code ends up being hidden from legacy Internet Explorer. Respond.js is an excellent polyfill, but if you\u2019re comfortable serving a single desktop layout to older IE, we don\u2019t need JavaScript. We simply need to capture layout code outside of a media query and sandbox it under an IE only class name.\n\n// set IE fallback layout to 8 columns\n$ie-support = 8;\n\n// inside of our breakpoint mixin (but outside the media query)\n@if ($ie-support and $min <= $ie-support) {\n\t.lt-ie9 { @content; }\n}\n\nPerspective Regained\n\nThinking in columns means you are thinking about content layout. How big of a screen do you need for 12 columns? Who cares? Having Sass write media queries means you can use intuitive numbers for content layout. A fixed grid means more layout control and less edge cases to test than a fluid grid. Using CSS labels for activating responsive images means you don\u2019t have to duplicate breakpoints across separations of concern. \n\nIt\u2019s a harmonious blend of approaches that gives us something we need\u2014responsive design that feels intuitive. And design that, from the very outset, focuses on what matters most. Just like our kindergarten teachers taught us: It\u2019s what\u2019s inside that counts.", "year": "2012", "author": "Les James", "author_slug": "lesjames", "published": "2012-12-13T00:00:00+00:00", "url": "https://24ways.org/2012/redesigning-the-media-query/", "topic": "code"}
{"rowid": 261, "title": "Surviving\u2014and Thriving\u2014as a Remote Worker", "contents": "Remote work is hot right now. Many people even say that remote work is the future. Why should a company limit itself to hiring from a specific geographic location when there\u2019s an entire world of talent out there?\nI\u2019ve been working remotely, full-time, for five and a half years. I\u2019ve reached the point where I can\u2019t even fathom working in an office. The idea of having to wake up at a specific time and commute into an office, work for eight hours, and then commute home, feels weirdly anachronistic. I\u2019ve grown attached to my current level of freedom and flexibility.\nHowever, it took me a lot of trial and error to reach success as a remote worker \u2014 and sometimes even now, I slip up. Working remotely requires a great amount of discipline, independence, and communication. It can feel isolating, especially if you lean towards the more extroverted side of the social spectrum. Remote working isn\u2019t for everyone, but most people, with enough effort, can make it work \u2014 or even thrive. Here\u2019s what I\u2019ve learned in over five years of working remotely.\nExperiment with your environment\nAs a remote worker, you have almost unprecedented control of your environment. You can often control the specific desk and chair you use, how you accessorize your home office space \u2014 whether that\u2019s a dedicated office, a corner of your bedroom, or your kitchen table. (Ideally, not your couch\u2026 but I\u2019ve been there.) Hate fluorescent lights? Change your lightbulbs. Cover your work area in potted plants. Put up blackout curtains and work in the dark like a vampire. Whatever makes you feel most comfortable and productive, and doesn\u2019t completely destroy your eyesight.\nWorking remotely doesn\u2019t always mean working from home. If you don\u2019t have a specific reason you need to work from home (like specialized equipment), try working from other environments (which is especially helpful it you have roommates, or children). Cafes are the quintessential remote worker hotspot, but don\u2019t just limit yourself to your favorite local haunt. More cities worldwide are embracing co-working spaces, where you can rent either a roaming spot or a dedicated desk. If you\u2019re a social person, this is a great way to build community in your work environment. Most have phone rooms, so you can still take calls.\nCo-working spaces can be expensive, and not everyone has either the extra income, or work-provided stipend, to work from one. Local libraries are also a great work location. They\u2019re quiet, usually have free wi-fi, and you have the added bonus of being able to check out books after work instead of, ahem, spending too much money on Kindle books. (I know most libraries let you check out ebooks, but reader, I am impulsive and impatient person. When I want a book now, I mean now.) \nJust be polite \u2014 make sure your headphones don\u2019t leak, and don\u2019t work from a library if you have a day full of calls.\nRemember, too, that you don\u2019t have to stay in the same spot all day. It\u2019s okay to go out for lunch and then resume work from a different location. If you find yourself getting restless, take a walk. Wash some dishes while you mull through a problem. Don\u2019t force yourself to sit at your desk for eight hours if that doesn\u2019t work for you.\nSet boundaries\nIf you\u2019re a workaholic, working remotely can be a challenge. It\u2019s incredibly easy to just\u2026 work. All the time. My work computer is almost always with me. If I remember at 11pm that I wanted to do something, there\u2019s nothing but my own willpower keeping me from opening up my laptop and working until 2am. Some people are naturally disciplined. Some have discipline instilled in them as children. And then some, like me, are undisciplined disasters that realize as adults that wow, I guess it\u2019s time to figure this out, eh?\nLearning how to set boundaries is one of the most important lessons I\u2019ve learned working remotely. (And honestly, it\u2019s something I still struggle with). \nFor a long time, I had a bad habit of waking up, checking my phone for new Slack messages, seeing something I need to react to, and then rolling over to my couch with my computer. Suddenly, it\u2019s noon, I\u2019m unwashed, unfed, starting to get a headache, and wondering why suddenly I hate all of my coworkers. Even when I finally tear myself from my computer to shower, get dressed, and eat, the damage is done. The rest of my day is pretty much shot.\nI recently had a conversation with a coworker, in which she remarked that she used to fill her empty time with work. Wake up? Scroll through Slack and email before getting out of bed. Waiting in line for lunch? Check work. Hanging out on her couch in the evening? You get the drift. She was only able to break the habit after taking a three month sabbatical, where she had no contact with work the entire time.\nI too had just returned from my own sabbatical. I took her advice, and no longer have work Slack on my phone, unless I need it for an event. After the event, I delete it. I also find it too easy to fill empty time with work. Now, I might wake up and procrastinate by scrolling through other apps, but I can\u2019t get sucked into work before I\u2019m even dressed. I\u2019ve gotten pretty good at forbidding myself from working until I\u2019m ready, but building any new habit requires intentionality. \nSomething else I experimented with for a while was creating a separate account on my computer for social tasks, so if I wanted to hang out on my computer in the evening, I wouldn\u2019t get distracted by work. It worked exceptionally well. The only problems I encountered were technical, like app licensing and some of my work proxy configurations. I\u2019ve heard other coworkers have figured out ways to work through these technical issues, so I\u2019m hoping to give it another try soon.\nYou might noticed that a lot of these ideas are just hacks for making myself not work outside of my designated work times. It\u2019s true! If you\u2019re a more disciplined person, you might not need any of these coping mechanisms. If you\u2019re struggling, finding ways to subvert your own bad habits can be the difference between thriving or burning out.\nCreate intentional transition time\nI know it\u2019s a stereotype that people who work from home stay in their pajamas all day, but\u2026 sometimes, it\u2019s very easy to do. I\u2019ve found that in order to reach peak focus, I need to create intentional transition time. \nThe most obvious step is changing into different clothing than I woke up in. Ideally, this means getting dressed in real human clothing. I might decide that it\u2019s cold and gross out and I want to work in joggers and a hoody all day, but first, I need to change out of my pajamas, put on a bra, and then succumb to the lure of comfort. \nI\u2019ve found it helpful to take similar steps at the end of my day. If I\u2019ve spent the day working from home, I try to end my day with something that occupies my body, while letting my mind unwind. Often, this is doing some light cleaning or dinner prep. If I try to go straight into another mentally heavy task without allowing myself this transition time, I find it hard to context switch. \nThis is another reason working from outside your home is advantageous. Commutes, even if it\u2019s a ten minute walk down the road, are great transition time. Lunch is a great transition time. You can decompress between tasks by going out for lunch, or cooking and eating lunch in your kitchen \u2014 not next to your computer. \nEmbrace async\nIf you\u2019re used to working in an office, you\u2019ve probably gotten pretty used to being able to pop over to a colleague\u2019s desk if you need to ask a question. They\u2019re pretty much forced to engage with you at that point. When you\u2019re working remotely, your coworkers might not be in the same timezone as you. They might take an hour to finish up a task before responding to you, or you might not get an answer for your entire day because dangit Gary\u2019s in Australia and it\u2019s 3am there right now. \nFor many remote workers, that\u2019s part of the package. When you\u2019re not co-located, you have to build up some patience and tolerance around waiting. You need to intentionally plan extra time into your schedule for waiting on answers.\nAsynchronous communication is great. Not everyone can be present for every meeting or office conversation \u2014 and the same goes for working remotely. However, when you\u2019re remote, you can read through your intranet messages later or scroll back a couple hours in Slack. My company has a bunch of internal blogs (\u201cp2s\u201d) where we record major decisions and hold asynchronous conversations. I feel like even if I missed a meeting, or something big happened while I was asleep, I can catch up later. We have a phrase \u2014 \u201cp2 or it didn\u2019t happen.\u201d\nWorking remotely has made me a better communicator largely because I\u2019ve gotten into the habit of making written updates. I\u2019ve also trained myself to wait before responding, which allows me to distance myself from what could potentially be an emotional reaction. (On the internet, no one can see you making that face.) Having the added space that comes from not being in the same physical location with somebody else creates an opportunity to rein myself in and take the time to craft an appropriate response, without having the pressure of needing to reply right meow. Lean into it!\n(That said, if you\u2019re stuck, sometimes the best course of action is to hop on a video call with someone and hash out the details. Use the tools most appropriate for the problem. They invented Zoom for a reason.)\nSeek out social opportunities\nEven introverts can feel lonely or isolated. When you work remotely, there isn\u2019t a built-in community you\u2019re surrounded by every day. You have to intentionally seek out social opportunities that an office would normally provide.\nI have a couple private Slack channels where I can joke around with work friends. Having that kind of safe space to socialize helps me feel less alone. (And, if the channels get too noisy, I can mute them for a couple hours.)\nEvery now and then, I\u2019ll also hop on a video call with some work friends and just hang out for a little while. It feels great to actually see someone laugh.\nIf you work from a co-working space, that space likely has events. My co-working space hosts social hours, holiday parties, and sometimes even lunch-and-learns. These events are great opportunities for making new friends and forging professional connections outside of work. \nIf you don\u2019t have access to a co-working space, your town or city likely has meetups. Create a Meetup.com account and search for something that piques your interest. If you\u2019ve been stuck inside your house for days, heads-down on a hard deadline, celebrate by getting out of the house. Get coffee or drinks with friends. See a show. Go to a religious service. Take a cooking class. Try yoga. Find excuses to be around someone other than your cats. When you can\u2019t fall back on your work to provide community, you need to build your own.\n\nThese are tips that I\u2019ve found help me, but not everyone works the same way. Remember that it\u2019s okay to experiment \u2014 just because you\u2019ve worked one way, doesn\u2019t mean that\u2019s the best way for you. Check in with yourself every now and then. Are you happy with your work environment? Are you feeling lonely, down, or exhausted? Try switching up your routine for a couple weeks and jot down how you feel at the end of each day. Look for patterns. You deserve to have a comfortable and productive work environment!\nHope to see you all online soon \ud83d\ude4c", "year": "2018", "author": "Mel Choyce", "author_slug": "melchoyce", "published": "2018-12-09T00:00:00+00:00", "url": "https://24ways.org/2018/thriving-as-a-remote-worker/", "topic": "process"}
{"rowid": 136, "title": "Making XML Beautiful Again: Introducing Client-Side XSL", "contents": "Remember that first time you saw XML and got it? When you really understood what was possible and the deep meaning each element could carry? Now when you see XML, it looks ugly, especially when you navigate to a page of XML in a browser. Well, with every modern browser now supporting XSL 1.0, I\u2019m going to show you how you can turn something as simple as an ATOM feed into a customised page using a browser, Notepad and some XSL.\n\nWhat on earth is this XSL?\n\nXSL is a family of recommendations for defining XML document transformation and presentation. It consists of three parts:\n\n\n\tXSLT 1.0 \u2013 Extensible Stylesheet Language Transformation, a language for transforming XML\n\tXPath 1.0 \u2013 XML Path Language, an expression language used by XSLT to access or refer to parts of an XML document. (XPath is also used by the XML Linking specification)\n\tXSL-FO 1.0 \u2013 Extensible Stylesheet Language Formatting Objects, an XML vocabulary for specifying formatting semantics\n\n\nXSL transformations are usually a one-to-one transformation, but with newer versions (XSL 1.1 and XSL 2.0) its possible to create many-to-many transformations too. So now you have an overview of XSL, on with the show\u2026\n\nSo what do I need?\n\nSo to get going you need a browser an supports client-side XSL transformations such as Firefox, Safari, Opera or Internet Explorer. Second, you need a source XML file \u2013 for this we\u2019re going to use an ATOM feed from Flickr.com. And lastly, you need an editor of some kind. I find Notepad++ quick for short XSLs, while I tend to use XMLSpy or Oxygen for complex XSL work. \n\nBecause we\u2019re doing a client-side transformation, we need to modify the XML file to tell it where to find our yet-to-be-written XSL file. Take a look at the source XML file, which originates from my Flickr photos tagged sky, in ATOM format.\n\nThe top of the ATOM file now has an additional <?xml-stylesheet /> instruction, as can been seen on Line 2 below. This instructs the browser to use the XSL file to transform the document.\n\n<?xml version=\"1.0\" encoding=\"utf-8\" standalone=\"yes\"?>\n<?xml-stylesheet type=\"text/xsl\" href=\"flickr_transform.xsl\"?>\n<feed xmlns=\"http://www.w3.org/2005/Atom\"\n\txmlns:dc=\"http://purl.org/dc/elements/1.1/\">\n\nYour first transformation\n\nYour first XSL will look something like this:\n\n<?xml version=\"1.0\" encoding=\"utf-8\"?>\n<xsl:stylesheet version=\"1.0\"\n\txmlns:xsl=\"http://www.w3.org/1999/XSL/Transform\"\n\txmlns:atom=\"http://www.w3.org/2005/Atom\"\n\txmlns:dc=\"http://purl.org/dc/elements/1.1/\">\n\t<xsl:output method=\"html\" encoding=\"utf-8\"/>\n</xsl:stylesheet>\n\nThis is pretty much the starting point for most XSL files. You will notice the standard XML processing instruction at the top of the file (line 1). We then switch into XSL mode using the XSL namespace on all XSL elements (line 2). In this case, we have added namespaces for ATOM (line 4) and Dublin Core (line 5). This means the XSL can now read and understand those elements from the source XML. \n\nAfter we define all the namespaces, we then move onto the xsl:output element (line 6). This enables you to define the final method of output. Here we\u2019re specifying html, but you could equally use XML or Text, for example. The encoding attributes on each element do what they say on the tin. As with all XML, of course, we close every element including the root.\n\nThe next stage is to add a template, in this case an <xsl:template /> as can be seen below:\n\n<?xml version=\"1.0\" encoding=\"utf-8\"?>\n<xsl:stylesheet version=\"1.0\"\n\txmlns:xsl=\"http://www.w3.org/1999/XSL/Transform\"\n\txmlns:atom=\"http://www.w3.org/2005/Atom\"\n\txmlns:dc=\"http://purl.org/dc/elements/1.1/\">\n\t<xsl:output method=\"html\" encoding=\"utf-8\"/>\n\t<xsl:template match=\"/\">\n\t\t<html>\n\t\t\t<head>\n\t\t\t\t<title>Making XML beautiful again : Transforming ATOM</title>\n\t\t\t</head>\n\t\t\t<body>\n\t\t\t\t<xsl:apply-templates select=\"/atom:feed\"/>\n\t\t\t</body>\n\t\t</html>\n\t</xsl:template>\n</xsl:stylesheet>\n\nThe beautiful thing about XSL is its English syntax, if you say it out loud it tends to make sense. \n\nThe / value for the match attribute on line 8 is our first example of XPath syntax. The expression / matches any element \u2013 so this <xsl:template/> will match against any element in the document. As the first element in any XML document is the root element, this will be the one matched and processed first.\n\nOnce we get past our standard start of a HTML document, the only instruction remaining in this <xsl:template/> is to look for and match all <atom:feed/> elements using the <xsl:apply-templates/> in line 14, above.\n\n<?xml version=\"1.0\" encoding=\"utf-8\"?>\n<xsl:stylesheet version=\"1.0\"\n\txmlns:xsl=\"http://www.w3.org/1999/XSL/Transform\"\n\txmlns:atom=\"http://www.w3.org/2005/Atom\"\n\txmlns:dc=\"http://purl.org/dc/elements/1.1/\">\n\t<xsl:output method=\"html\" encoding=\"utf-8\"/>\n\t<xsl:template match=\"/\">\n\t\t<xsl:apply-templates select=\"/atom:feed\"/>\n\t</xsl:template>\n\t<xsl:template match=\"/atom:feed\">\n\t\t<div id=\"content\">\n\t\t\t<h1>\n\t\t\t\t<xsl:value-of select=\"atom:title\"/>\n\t\t\t</h1>\n\t\t\t<p>\n\t\t\t\t<xsl:value-of select=\"atom:subtitle\"/>\n\t\t\t</p>\n\t\t\t<ul id=\"entries\">\n\t\t\t\t<xsl:apply-templates select=\"atom:entry\"/>\n\t\t\t</ul>\n\t\t</div>\n\t</xsl:template>\n</xsl:stylesheet>\n\nThis new template (line 12, above) matches <feed/> and starts to write the new HTML elements out to the output stream. The <xsl:value-of/> does exactly what you\u2019d expect \u2013 it finds the value of the item specifed in its select attribute. With XPath you can select any element or attribute from the source XML. \n\nThe last part is a repeat of the now familiar <xsl:apply-templates/> from before, but this time we\u2019re using it inside of a called template. Yep, XSL is full of recursion\u2026\n\n<xsl:template match=\"atom:entry\">\n\t<li class=\"entry\">\n\t\t<h2>\n\t\t\t<a href=\"{atom:link/@href}\">\n\t\t\t\t<xsl:value-of select=\"atom:title\"/>\n\t\t\t</a>\n\t\t</h2>\n\t\t<p class=\"date\">\n\t\t\t(<xsl:value-of select=\"substring-before(atom:updated,'T')\"/>)\n\t\t</p>\n\t\t<p class=\"content\">\n\t\t\t<xsl:value-of select=\"atom:content\" disable-output-escaping=\"yes\"/>\n\t\t</p>\n\t\t<xsl:apply-templates select=\"atom:category\"/>\n\t</li>\n</xsl:template>\n\nThe <xsl:template/> which matches atom:entry (line 1) occurs every time there is a <entry/> element in the source XML file. So in total that is 20 times, this is naturally why XSLT is full of recursion. This <xsl:template/> has been matched and therefore called higher up in the document, so we can start writing list elements directly to the output stream. The first part is simply a <h2/> with a link wrapped within it (lines 3-7). We can select attributes using XPath using @. \n\nThe second part of this template selects the date, but performs a XPath string function on it. This means that we only get the date and not the time from the string (line 9). This is achieved by getting only the part of the string that exists before the T. \n\nRegular Expressions are not part of the XPath 1.0 string functions, although XPath 2.0 does include them. Because of this, in XSL we tend to rely heavily on the available XML output. \n\nThe third part of the template (line 12) is a <xsl:value-of/> again, but this time we use an attribute of <xsl:value-of/> called disable output escaping to turn escaped characters back into XML. \n\nThe very last section is another <xsl:apply-template/> call, taking us three templates deep. Do not worry, it is not uncommon to write XSL which go 20 or more templates deep!\n\n<xsl:template match=\"atom:category\">\n\t<xsl:for-each select=\".\">\n\t\t<xsl:element name=\"a\">\n\t\t\t<xsl:attribute name=\"rel\">\n\t\t\t\t<xsl:text>tag</xsl:text>\n\t\t\t</xsl:attribute>\n\t\t\t<xsl:attribute name=\"href\">\n\t\t\t\t<xsl:value-of select=\"concat(@scheme, @term)\"/>\n\t\t\t</xsl:attribute>\n\t\t\t<xsl:value-of select=\"@term\"/>\n\t\t</xsl:element>\n\t\t<xsl:text> </xsl:text>\n\t</xsl:for-each>\n</xsl:template>\n\nIn our final <xsl:template/>, we see a combination of what we have done before with a couple of twists. Once we match atom:category we then count how many elements there are at that same level (line 2). The XPath . means \u2018self\u2019, so we count how many category elements are within the <entry/> element. \n\nFollowing that, we start to output a link with a rel attribute of the predefined text, tag (lines 4-6). In XSL you can just type text, but results can end up with strange whitespace if you do (although there are ways to simply remove all whitespace). \n\nThe only new XPath function in this example is concat(), which simply combines what XPaths or text there might be in the brackets. We end the output for this tag with an actual tag name (line 10) and we add a space afterwards (line 12) so it won\u2019t touch the next tag. (There are better ways to do this in XSL using the last() XPath function). \n\nAfter that, we go back to the <xsl:for-each/> element again if there is another category element, otherwise we end the <xsl:for-each/> loop and end this <xsl:template/>.\n\nA touch of style\n\nBecause we\u2019re using recursion through our templates, you will find this is the end of the templates and the rest of the XML will be ignored by the parser. Finally, we can add our CSS to finish up. (I have created one for Flickr and another for News feeds)\n\n<style type=\"text/css\" media=\"screen\">@import \"flickr_overview.css?v=001\";</style>\n\nSo we end up with a nice simple to understand but also quick to write XSL which can be used on ATOM Flickr feeds and ATOM News feeds. With a little playing around with XSL, you can make XML beautiful again.\n\nAll the files can be found in the zip file (14k)", "year": "2006", "author": "Ian Forrester", "author_slug": "ianforrester", "published": "2006-12-07T00:00:00+00:00", "url": "https://24ways.org/2006/beautiful-xml-with-xsl/", "topic": "code"}
{"rowid": 91, "title": "Infinite Canvas: Moving Beyond the Page", "contents": "Remember Web 2.0? I do. In fact, that phrase neatly bifurcates my life on the internet. Pre-2.0, I was occupied by chatting on AOL and eventually by learning HTML so I could build sites on Geocities. Around 2002, however, I saw a WYSIWYG demo in Dreamweaver. The instructor was dragging boxes and images around a canvas. With a few clicks he was able to build a dynamic, single-page interface. Coming from the world of tables and inline HTML styles, I was stunned.\n\nAs I entered college the next year, the web was blossoming: broadband, Wi-Fi, mobile (proud PDA owner, right here), CSS, Ajax, Bloglines, Gmail and, soon, Google Maps. I was a technology fanatic and a hobbyist web developer. For me, the web had long been informational. It was now rapidly becoming something else, something more: sophisticated, presentational, actionable.\n\nIn 2003 we watched as the internet changed. The predominant theme of those early Web 2.0 years was the withering of Internet Explorer 6 and the triumph of web standards. Upon cresting that mountain, we looked around and collectively breathed the rarefied air of pristine HMTL and CSS, uncontaminated by toxic hacks and forks \u2013 only to immediately begin hurtling down the other side at what is, frankly, terrifying speed.\n\nTen years later, we are still riding that rocket. Our days (and nights) are spent cramming for exams on CSS3 and RWD and Sass and RESS. We are the proud, frazzled owners of tiny pocket computers that annihilate the best laptops we could have imagined, and the architects of websites that are no longer restricted to big screens nor even segregated by device. We dragoon our sites into working any time, anywhere. At this point, we can hardly ask the spec developers to slow down to allow us to catch our breath, nor should we. It is, without a doubt, a most wonderful time to be a web developer.\n\nBut despite the newfound luxury of rounded corners, gradients, embeddable fonts, low-level graphics APIs, and, glory be, shadows, the canyon between HTML and native appears to be as wide as ever. The improvements in HTML and CSS have, for the most part, been conveniences rather than fundamental shifts. What I\u2019d like to do now, if you\u2019ll allow me, is outline just a few of the remaining gaps that continue to separate web sites and applications from their native companions.\n\nWhat I\u2019d like for Christmas\n\nThere is one irritant which is the grandfather of them all, the one from which all others flow and have their being, and it is, simply, the page refresh. That\u2019s right, the foundational principle of the web is our single greatest foe. To paraphrase a patron saint of designers everywhere, if you see a page refresh, we blew it.\n\nThe page refresh brings with it, of course, many noble and lovely benefits: addressability, for one; and pagination, for another. (See also caching, resource loading, and probably half a dozen others.) Still, those concerns can be answered (and arguably answered more compellingly) by replacing the weary page with the young and hearty document. Flash may be dead, but it has many lessons yet to bequeath.\n\nPreparing a single document when the site loads allows us to engage the visitor in a smooth and engrossing experience. We have long known this, of course. Twitter was not the first to attempt, via JavaScript, to envelop the user in a single-page application, nor the first to abandon it. Our shared task is to move those technologies down the stack, to make them more primitive, so that the next Twitter can be built with the most basic combination of HTML and CSS rather than relying on complicated, slow, and unreliable scripted solutions.\n\nSo, let\u2019s take a look at what we can do, right now, that we might have a better idea of where our current tools fall short.\n\nA print magazine in HTML clothing\n\nLike many others, I suspect, one of my earliest experiences with publishing was laying out newsletters and newspapers on a computer for print. If you\u2019ve ever used InDesign or Quark or even Microsoft Publisher, you\u2019ll remember reflowing content from page to page. The advent of the internet signaled, in many ways, the abandonment of that model. Articles were no longer constrained by the physical limitations of paper. In shedding our chains, however, it is arguable that we\u2019ve lost something useful. We had a self-contained and complete package, a closed loop. It was a thing that could be handled and finished, and doing so provided a sense of accomplishment that our modern, infinitely scrolling, ever-fractal web of content has stolen.\n\nFor our purposes today, we will treat 24 ways as the online equivalent of that newspaper or magazine. A single year\u2019s worth of articles could easily be considered an issue. Right now, navigating between articles means clicking on the article you\u2019d like to view and being taken to that specific address via a page reload. If Drew wanted to, it wouldn\u2019t be difficult to update the page in place (via JavaScript) and change the address (again via JavaScript with the History API) to reflect the new content found at the new location. But what if Drew wanted to do that without  JavaScript? And what if he wanted the site to not merely load the content but actually whisk you along the page in a compelling and delightful way, \u00e0 la the Mag+ demo we all saw a few years ago when the iPad was first introduced? Uh, no.\n\nWe\u2019re all familiar with websites that have attempted to go beyond the page by weaving many chunks of content together into a large document and for good reason. There is tremendous appeal in opening and exploring the canvas beyond the edges of our screens.\n\nIn one rather straightforward example from last year, Mozilla contacted Full Stop to build a website promoting Aza Raskin\u2019s proposal for a set of Creative Commons-style privacy icons. Like a lot of the sites we build (including our own), the amount of information we were presenting was minimal. In these instances, we encourage our clients to consider including everything on a single page. The result was a horizontally driven site that was, if not whimsical, at least clever and attractive to the intended audience. An experience that is taken for granted when using device-native technology is utterly, maddeningly impossible to replicate on the web without jumping through JavaScript hoops.\n\nIn another, more complex example, we again had the pleasure of working with Aza earlier this year, this time on a redesign of the Massive Health website. Our assignment was to design and build a site that communicated Massive\u2019s commitment to modern personal health. The site had to be visually and interactively stunning while maintaining a usable and clear interface for the casual visitor. Our solution was to extend the infinite company logo into a ribbon that carried the visitor through the site narrative. It also meant we\u2019d be asking the browser to accommodate something it was never designed to handle: a non-linear design. (Be sure to play around. There\u2019s a lot going on under the hood. We were also this close to a ZUI, if WebKit didn\u2019t freak out when pages were scaled beyond 10\u00d7.) Despite the apparent and deliberate design simplicity, the techniques necessary to implement it are anything but. From updating the URL to moving the visitor from section to section, we\u2019re firmly in JavaScript territory. And that\u2019s a shame.\n\nWhat can we do?\n\nWe might not be able to specify these layouts in HTML and CSS just yet, but that doesn\u2019t mean we can\u2019t learn a few new tricks while we wait. Let\u2019s see how close we can come to recreating the privacy icons design, the Massive design, or the Mag+ design without resorting to JavaScript.\n\nA horizontally paginated site\n\nThe first thing we\u2019re going to need is the concept of a page within our HTML document. Using plain old HTML and CSS, we can stack a series of <div>s sideways (with a little assist from our new friend, the viewport-width unit, not that he was strictly necessary). All we need to know is how many pages we have. (And, boy, wouldn\u2019t it be nice to be able to know that without having to predetermine it or use JavaScript?)\n\n.window {\noverflow: hidden;\n  width: 100%;\n}\n.pages {\n  width: 200vw;\n}\n.page {\n  float: left;\n  overflow: hidden;\n  width: 100vw;\n}\n\nIf you look carefully, you\u2019ll see that the conceit we\u2019ll use in the rest of the demos is in place. Despite the document containing multiple pages, only one is visible at any given time. This allows us to keep the user focused on the task (or content) at hand.\n\nBy the way, you\u2019ll need to use a modern, WebKit-based browser for these demos. I recommend downloading the WebKit nightly builds, Chrome Canary, or being comfortable with setting flags in Chrome.\n\nA horizontally paginated site, with transitions\n\nAh, here\u2019s the rub. We have functional navigation, but precious few cues for the user. It\u2019s not much good shoving the visitor around various parts of the document if they don\u2019t get the pleasant whooshing experience of the journey. You might be thinking, what about that new CSS selector, target-something\u2026? Well, my friend, you\u2019re on the right track. Let\u2019s test it. We\u2019re going to need to use a bit of sleight of hand. While we\u2019d like to simply offset the containing element by the number of pages we\u2019re moving (like we did on Massive), CSS alone can\u2019t give us that information, and that means we\u2019re going to need to fake it by expanding and collapsing pages as you navigate. Here are the bits we\u2019re going to need:\n\n.page {\n  -webkit-transition: width 1s; // Naturally you're going to want to include all the relevant prefixes here\n  float: left;\n  left: 0;\n  overflow: hidden;\n  position: relative;\n  width: 100vw;\n}\n.page:not(:target) {\n  width: 0;\n}\n\nAh, but we\u2019re not fooling anyone with that trick. As soon as you move beyond a single page, the visitor\u2019s disbelief comes tumbling down when the linear page transitions are unaffected by the distance the pages are allegedly traveling. And you may have already noticed an even more fatal flaw: I secretly linked you to the first page rather than the unadorned URL. If you visit the same page with no URL fragment, you get a blank screen. Sure, we could force a redirect with some server-side trickery, but that feels like cheating. Perhaps if we had the CSS4 subject selector we could apply styles to the parent based on the child being targeted by the URL. We might also need a few more abilities, like determining the total number of pages and having relative sibling selectors (e.g. nth-sibling), but we\u2019d sure be a lot closer.\n\nA horizontally paginated site, with transitions \u2013 no cheating\n\nWell, what other cards can we play? How about the checkbox hack? Sure, it\u2019s a garish trick, but it might be the best we can do today. Check it out. \n\nlabel {\n  cursor: pointer;\n}\ninput {\n display: none;\n}\ninput:not(:checked) + .page {\n  max-height: 100vh;\n  width: 0;\n}\n\nFinally, we can see the first page thanks to the state we are able to set on the appropriate radio button. Of course, now we don\u2019t have URLs, so maybe this isn\u2019t a winning plan after all. While our HTML and CSS toolkit may feel primitive at the moment, we certainly don\u2019t want to sacrifice the addressability of the web. If there\u2019s one bedrock principle, that\u2019s it.\n\nA horizontally paginated site, with transitions \u2013 no cheating and a gorgeous homepage\n\nGorgeous may not be the right word, but our little magazine is finally shaping up. Thanks to the CSS regions spec, we\u2019ve got an exciting new power, the ability to begin an article in one place and bend it to our will. (Remember, your everyday browser isn\u2019t going to work for these demos. Try the WebKit nightly build to see what we\u2019re talking about.) As with the rest of the examples, we\u2019re clearly abusing these features. Off-canvas layouts (you can thank Luke Wroblewski for the name) are simply not considered to be normal patterns\u2026 yet.\n\nHere\u2019s a quick look at what\u2019s going on:\n\n.excerpt-container {\n  float: left;\n  padding: 2em;\n  position: relative;\n  width: 100%;\n}\n.excerpt {\n  height: 16em;\n}\n.excerpt_name_article-1,\n.page-1 .article-flow-region {\n  -webkit-flow-from: article-1;\n}\n.article-content_for_article-1 {\n  -webkit-flow-into: article-1;\n}\n\nThe regions pattern is comprised of at least three components: a beginning; an ending; and a source. Using CSS, we\u2019re able to define specific elements that should be available for the content to flow through. If magazine-style layouts are something you\u2019re interested in learning more about (and you should be), be sure to check out the great work Adobe has been doing.\n\nLooking forward, and backward\n\nAs designers, builders, and consumers of the web, we share a desire to see the usability and enjoyability of websites continue to rise. We are incredibly lucky to be working in a time when a three-month-old website can be laughably outdated. Our goal ought to be to improve upon both the weaknesses and the strengths of the web platform. We seek not only smoother transitions and larger canvases, but fine-grained addressability. Our URLs should point directly and unambiguously to specific content elements, be they pages, sections, paragraphs or words. Moreover, off-screen design patterns are essential to accommodating and empowering the multitude of devices we use to access the web. We should express the desire that interpage links take advantage of the CSS transitions which have been put to such good effect in every other aspect of our designs. Transitions aren\u2019t just nice to have, they\u2019re table stakes in the highly competitive world of native applications. \n\nThe tools and technologies we have right now allow us to create smart, beautiful, useful webpages. With a little help, we can begin removing the seams and sutures that bind the web to an earlier, less sophisticated generation.", "year": "2012", "author": "Nathan Peretic", "author_slug": "nathanperetic", "published": "2012-12-21T00:00:00+00:00", "url": "https://24ways.org/2012/infinite-canvas-moving-beyond-the-page/", "topic": "code"}
{"rowid": 202, "title": "Design Systems and CSS Grid", "contents": "Recently, my client has been looking at creating a few new marketing pages for their website. They currently have a design system in place but they\u2019re looking to push this forward into 2018 with some small and possibly some larger changes.\nTo start with we are creating a couple of new marketing pages. As well as making use of existing components within the design systems component library there are a couple of new components. Looking at the first couple of sketch files I felt this would be a great opportunity to use CSS Grid, to me the newer components need to be laid out on that page and grid would help with this perfectly.\n\nAs well as this layout of the new components and the text within it, imagery would be used that breaks out of the grid and pushes itself into the spaces where the text is aligned.\nThe existing grid system\nWhen the site was rebuilt in 2015 the team decided to make use of Sass and Susy, a \u201clightweight grid-layout engine using Sass\u201d.  It was built separating the grid system from the components that would be laid out on the page with a container, a row, an optional column, and a block.\nTo make use of the grid system on a page for a component that would take the full width of the row you would have to write something like this:\n<div class=\"grid-container\">\n  <div class=\"grid-row\">\n    <div class=\"grid-column-4\">\n      <div class=\"grid-block\">\n        <!-- component code here -->\n      </div>\n    </div>\n  </div>\n</div>\nUsing a grid system similar to this can easily create quite the tag soup. It could fill the HTML full of divs that may become complex to understand and difficult to edit.\nAlthough there is this reliance on several <div>s to lay out the components on a page it does allow a tidy way to place the component code within that page. It abstracts the layout of the page to its own code, its own system, so the components can \u2018fit\u2019 where needed.\nThe requirements of the new grid system\nMoving forward I set myself some goals for what I\u2019d like to have achieved in this new grid system:\nIt needs to behave like the existing grid systems\nWe are not ripping up the existing grid system, it would be too much work, for now,  to retrofit all of the existing components to work in a grid that has a different amount of columns, and spacing at various viewport widths.\nAllow full-width components\nCurrently the grid system is a 14 column grid that becomes centred on the page when viewport is wide enough. We have, in the past, written some CSS that would allow for a full-width component, but his had always felt like a hack. We want the option to have a full-width element as part of the new grid system, not something that needs CSS to fight against.\nLess of a tag soup\nIdeally we want to end up writing less HTML to layout the page. Although the existing system can be quite clear as to what each element is doing, it can also become a little laborious in working out what each grid row or block is doing where.\nI would like to move the layout logic to CSS as much as is possible, potentially creating some utility classes or additional \u2018layout classes\u2019 for the components.\nEasier for people to use and author\nWith many people using the existing design systems codebase  we need to create a new grid system that is as easy or easier to use than the existing one. I think and hope this would be helped by removing as many <div>s as needed and would require new documentation and examples, and potentially some initial training.\nSeparating layout from style\nThere still needs to be a separation of layout from the styles for the component. To allow for the component itself to be placed wherever needed in the page we need to make sure that the CSS for the layout is a separate entity to the CSS for that styling.\nWith these base requirements I took to CodePen and started working on some throwaway code to get started.\nMaking the new grid(s)\nThe Full-Width Grid\nTo start with I created a grid that had three columns, one for the left, one for the middle, and one for the right. This would give the full-width option to components.\nThankfully, one of Rachel Andrew\u2019s many articles on Grid discussed this exact requirement of the new grid system to break out with Grid.\nI took some of the code in the examples and edited to make grid we needed.\n.container {\n  display: grid;\n  grid-template-columns:\n    [full-start]\n      minmax(.75em, 1fr)\n        [main-start]\n          minmax(0, 1008px)\n        [main-end]\n      minmax(.75em, 1fr)\n    [full-end];\n}\nWe are declaring a grid, we have four grid column lines which we name and we define how the three columns they create react to the viewport width. We have a left and right column that have a minimum of 12px, and a central column with a maximum width of 1008px.\nBoth left and right columns fill up any additional space if the viewport is wider that 1032px wide. We are also not declaring any gutters to this grid, the left and right columns would act as gutters at smaller viewports.\nAt this point I noticed that older versions of Sass cannot parse the brackets in this code. To combat this I used Sass\u2019 unquote method  to wrap around the value of the grid-template-column.\n.container {\n  display: grid;\n  grid-template-columns:\n  unquote(\"\n    [full-start]\n      minmax(.75em, 1fr)\n        [main-start]\n          minmax(0, 1008px)\n        [main-end]\n      minmax(.75em, 1fr)\n    [full-end]\n  \");\n}\nThe existing codebase makes use of Sass variables, mixins and functions so to remove that would be a problem, but luckily the version of Sass used is up-to-date (note: example CodePens will be using CSS).\nThe initial full-width grid displays on a webpage as below:\n\nThe 14 column grid\nI decided to work out the 14 column grid as a separate prototype before working out how it would fit within the full-width grid. This grid is very similar to the 12 column grids that have been used in web design. Here we need 14 columns with a gutter between each one.\nAlong with the many other resources on Grid, Mozilla\u2019s MDN site had a page on common layouts using CSS Grid. This gave me the perfect CSS I needed to create my grid and I edited it as required:\n.inner {\n  display: grid;\n  grid-template-columns: repeat(14, [col-start] 1fr);\n  grid-gap: .75em;\n}\nWe, again, are declaring a grid, and we are splitting up the available space by creating 14 columns with 1 fr-unit and giving each one a starting line named col-start.\nThis grid would display on web page as below:\n\nBringing the grids together\nNow that we have got the two grids we need to help fulfil our requirements we need to put them together so that they are actually we we need.\nThe subgrid\nThere is no subgrid in CSS, yet. To workaround this for the new grid system we could nest the 14 column grid inside the full-width grid.\nIn the HTML we nest the 14 column inner grid inside the full-width container.\n<div class=\"container\">\n  <div class=\"inner\">\n  </div>\n</div>\nSo that the inner knows where to be laid out within the container we tell it what column to start and end with, with this code it would be the start and end of the main column.\n.inner {\n  display: grid;\n  grid-column: main-start / main-end;\n  grid-template-columns: repeat(14, [col-start] 1fr);\n  grid-gap: .75em;\n}\nThe CSS for the container remains unchanged.\n\nThis works, but we have added another div to our HTML. One of our requirements is to try and remove the potential for tag soup.\nThe faux subgrid subgrid\nI wanted to see if it would be possible to place the CSS for the 14 column grid within the CSS for the full-width grid. I replaced the CSS for the main grid and added the grid-column-gap to the .container.\n.container {\n  display: grid;\n  grid-gap: .75em;\n  grid-template-columns:\n    [full-start]\n      minmax(.75em, 1fr)\n        [main-start]\n          repeat(14, [col-start] 1fr)\n        [main-end]\n      minmax(.75em, 1fr)\n    [full-end];\n}\nWhat this gave me was a 16 column grid. I was unable to find a way to tell the main grid, the grid betwixt main-start and main-end to be a maximum of 1008px as required.\n\nI trawled the internet to find if it was possible to create our main requirement, a 14 column grid which also allows for full-width components. I found that we could not reverse minmax to minmax(1fr, 72px) as 1fr is not allowed as a minimum if there is a maximum. I tried working out if we could make the min larger than its max but in minmax it would be ignored.\nI was struggling, I was hoping for a cleaner version of the grid system we currently use but getting to the point where needing that extra <div> would be a necessity.\nAt 3 in the morning, when I was failing to get to sleep, my mind happened upon an question: \u201cCould you use calc?\u201d\nAt some point I drifted back to sleep so the next day I set upon seeing if this was possible. I knew that the maximum width of the central grid needed to be 1008px. The left and right columns needed to be however many pixels were left in the viewport divided by 2. In CSS it looked like I would need to use calc twice. The first time to takeaway 1008px from 100% of the viewport width and the second to divide that result by 2.\ncalc(calc(100% - 1008px) / 2)\nThe CSS above was part of the value that I would need to include in the declaration for the grid.\n.container {\n  display: grid;\n  grid-gap: .75em;\n  grid-template-columns:\n    [full-start]\n      minmax(calc(calc(100% - 1008px) / 2), 1fr)\n        [main-start]\n          repeat(14, [col-start] 1fr)\n        [main-end]\n      minmax(calc(calc(100% - 1008px) / 2), 1fr)\n    [full-end];\n}\nWe have created the grid required. A full-width grid, with a central 14 column grid, using fewer <div> elements.\n\nSee the Pen Design Systems and CSS Grid, 6 by Stuart Robson (@sturobson) on CodePen.\n\nSuccess!\nProgressive enhancement\nNow that we have created the grid system required we need to back-track a little.\nNot all browsers support Grid, over the last 9 months or so this has gotten a lot better. However there will still be browsers that visit that potentially won\u2019t have support. The effort required to make the grid system fall back for these browsers depends on your product or sites browser support.\n\nTo determine if we will be using Grid or not for a browser we will make use of  feature queries. This would mean that any version of Internet Explorer will not get Grid, as well as some mobile browsers and older versions of other browsers.\n@supports (display: grid) {\n /* Styles for browsers that support Grid */\n}\nIf a browser does not pass the requirements for @supports we will fallback to using flexbox where possible, and if that is not supported we are happy for the page to be laid out in one column.\nA website doesn\u2019t have to look the same in every browser after all.\nA responsive grid\nWe started with the big picture, how the grid would be at a large viewport and the grid system we have created gets a little silly when the viewport gets smaller.\nAt smaller viewports we have a single column layout where every item of content, every component stacks atop each other. We don\u2019t start to define a grid before we the viewport gets to 700px wide. At this point we have an 8 column grid and if the viewport gets to 1100px or wider  we have our 14 column grid.\n/*\n * to start with there is no 'grid' just a single column\n */\n.container {\n  padding: 0 .75em;\n}\n\n/*\n * when we get to 700px we create an 8 column grid with\n * a left and right area to breakout of the grid.\n */\n@media (min-width: 700px) {\n  .container {\n    display: grid;\n    grid-gap: .75em;\n    grid-template-columns:\n      [full-start]\n        minmax(calc(calc(100% - 1008px) / 2), 1fr)\n          [main-start]\n            repeat(8, [col-start] 1fr)\n          [main-end]\n        minmax(calc(calc(100% - 1008px) / 2), 1fr)\n      [full-end];\n    padding: 0;\n  }\n}\n\n/*\n * when we get to 1100px we create an 14 column grid with\n * a left and right area to breakout of the grid.\n */\n@media (min-width: 1100px) {\n  .container {\n    grid-template-columns:\n    [full-start]\n      minmax(calc(calc(100% - 1008px) / 2), 1fr)\n        [main-start]\n          repeat(14, [col-start] 1fr)\n        [main-end]\n      minmax(calc(calc(100% - 1008px) / 2), 1fr)\n    [full-end];\n  }\n}\nBeing explicit in creating this there is some repetition that we could avoid, we will define the number of columns for the inner grid by using a Sass variable or CSS custom properties (more commonly termed as CSS variables).\nLet\u2019s use CSS custom properties. We need to declare the variable first by adding it to our stylesheet.\n:root {\n  --inner-grid-columns: 8;\n}\nWe then need to edit a few more lines. First make use of the variable for this line.\nrepeat(8, [col-start] 1fr)\n/* replace with */\nrepeat(var(--inner-grid-columns), [col-start] 1fr)\nThen at the 1100px breakpoint we would only need to change the value of the \u2014inner-grid-columns value.\n@media (min-width: 1100px) {\n  .container {\n    grid-template-columns:\n    [full-start]\n      minmax(calc(calc(100% - 1008px) / 2), 1fr)\n        [main-start]\n          repeat(14, [col-start] 1fr)\n        [main-end]\n      minmax(calc(calc(100% - 1008px) / 2), 1fr)\n    [full-end];\n  }\n}\n/* replace with */\n@media (min-width: 1100px) {\n  .container {\n    --inner-grid-columns: 14;\n  }\n}\nSee the Pen Design Systems and CSS Grid, 8 by Stuart Robson (@sturobson) on CodePen.\n\nThe final grid system\nWe have finally created our new grid for the design system. It stays true to the existing grid in place, adds the ability to break-out of the grid, removes a <div> that could have been needed for the nested 14 column grid.\nWe can move on to the new component.\nCreating a new component\nBack to the new components we are needing to create.\n\nTo me there are two components one of which is a slight variant of the first. This component contains a title, subtitle, a paragraph (potentially paragraphs) of content, a list, and a call to action.\nTo start with we should write the HTML for the component, something like this:\n<article class=\"features\">\n  <h3 class=\"features__title\"></h3>\n  <p class=\"features__subtitle\"></p>\n  <div class=\"features__content\">\n    <p class=\"features__paragraph\"></p>\n  </div>\n  <ul class=\"features__list\">\n    <li></li>\n    <li></li>\n  </ul>\n  <a href=\"\" class=\"features__button\"></a>\n</article>\nTo place the component on the existing grid is fine, but as child elements are not affected by the container grid we need to define another grid for the features component.\nAs the grid doesn\u2019t get invoked until 700px it is possible to negate the need for a media query.\n.features {\n  grid-column: col-start 1 / span 6;\n}\n\n@supports (display: grid) {\n  @media (min-width: 1100px) {\n    .features {\n      grid-column-end: 9;\n    }\n  }\n}\nWe can also avoid duplication of declarations by making use of the grid-column shorthand and longhand. We need to write a little more CSS for the variant component, the one that will sit on the right side of the page too.\n.features:nth-of-type(even) {\n  grid-column-start: 4;\n  grid-row: 2;\n}\n\n@supports (display: grid) {\n  @media (min-width: 1100px) {\n    .features:nth-of-type(even) {\n      grid-column-start: 9;\n      grid-column-end: 16;\n    }\n  }\n}\nWe cannot place the items within features on the container grid as they are not direct children. To make this work we have to define a grid for the features component.\nWe can do this by defining the grid at the first breakpoint of 700px making use of CSS custom properties again to define how many columns there will need to be.\n.features {\n  grid-column: col-start 1 / span 6;\n  --features-grid-columns: 5;\n}\n\n@supports (display: grid) {\n  @media (min-width: 700px) {\n    .features {\n      display: grid;\n    grid-gap: .75em;\n      grid-template-columns: repeat(var(--features-grid-columns), [col-start] 1fr);\n    }\n  }\n}\n\n@supports (display: grid) {\n  @media (min-width: 1100px) {\n    .features {\n      grid-column-end: 9;\n      --features-grid-columns: 7;\n    }\n  }\n}\nSee the Pen Design Systems and CSS Grid, 10 by Stuart Robson (@sturobson) on CodePen.\n\nLaying out the parts\nLooking at the spec and reading several articles I feel there are two ways that I could layout the text of this component on the grid.\nWe could use the grid-column shorthand that incorporates grid-column-start and grid-column-end or we can make use of grid-template-areas.\ngrid-template-areas allow for a nice visual way of representing how the parts of the component would be laid out. We can take the the mock of the features on the grid and represent them in text in our CSS.\n\nWithin the .features  rule we can add the relevant grid-template-areas value to represent the above.\n.features {\n  display: grid;\n  grid-template-columns: repeat(var(--features-grid-columns), [col-start] 1fr);\n  grid-template-areas:\n   \". title     title     title     title     title    title\"\n   \". subtitle  subtitle  subtitle  subtitle  subtitle .    \"\n   \". content   content   content   content   .        .    \"\n   \". list      list      list      .         .        .    \"\n   \". .         .         .         link      link     link \";\n}\n\nIn order to make the variant of the component we would have to create the grid-template-areas for that component too.\nWe then need to tell each element of the component in what grid-area it should be placed within the grid.\n.features__title { grid-area: title; }\n.features__subtitle { grid-area: subtitle; }\n.features__content { grid-area: content; }\n.features__list { grid-area: list; }\n.features__link { grid-area: link; }\nSee the Pen Design Systems and CSS Grid, 12 by Stuart Robson (@sturobson) on CodePen.\n\nThe other way would be to use the grid-column shorthand and the grid-column-start and grid-column-end we have used previously.\n.features .features__title {\n  grid-column: col-start 2 / span 6;\n}\n.features .features__subtitle {\n  grid-column: col-start 2 / span 5;\n}\n.features .features__content {\n  grid-column: col-start 2 / span 4;\n}\n.features .features__list {\n  grid-column: col-start 2 / span 4;\n}\n.features .features__link {\n  grid-column: col-start 5 / span 3;\n}\nFor the variant of the component we can use the grid-column-start property as it will inherit the span defined in the grid-column shorthand.\n.features:nth-of-type(even) .features__title {\n  grid-column-start: col-start 1;\n}\n.features:nth-of-type(even) .features__subtitle {\n  grid-column-start: col-start 1;\n}\n.features:nth-of-type(even) .features__content {\n  grid-column-start: col-start 3;\n}\n.features:nth-of-type(even) .features__list {\n  grid-column-start: col-start 3;\n}\n.features:nth-of-type(even) .features__link {\n  grid-column-start: col-start 1;\n}\nSee the Pen Design Systems and CSS Grid, 14 by Stuart Robson (@sturobson) on CodePen.\n\nI think, for now, we will go with using grid-column properties rather than grid-template-areas. The repetition needed for creating the variant feels too much where we can change the grid-column-start instead, keeping the components elements layout properties tied a little closer to the elements rather than the grid.\nSome additional decisions\nThe current component library has existing styles for titles, subtitles, lists, paragraphs of text and calls to action. These are name-spaced so that they shouldn\u2019t clash with any other components. Looking forward there will be a chance that other products adopt the component library, but they may bring their own styles for titles, subtitles, etc.\nOne way that we could write our code now for that near future possibility is to make sure our classes are working hard. Using class-attribute selectors we can target part of the class attributes that we know the elements in the component will have using *=.\n.features [class*=\"title\"]  {\n  grid-column: col-start 2 / span 6;\n}\n.features [class*=\"subtitle\"] {\n  grid-column: col-start 2 / span 5;\n}\n.features [class*=\"content\"] {\n  grid-column: col-start 2 / span 4;\n}\n.features [class*=\"list\"] {\n  grid-column: col-start 2 / span 4;\n}\n.features [class*=\"link\"]  {\n  grid-column: col-start 5 / span 3;\n}\nSee the Pen Design Systems and CSS Grid, 15 by Stuart Robson (@sturobson) on CodePen.\n\nAlthough the component we have created have a title, subtitle, paragraphs, a list, and a call to action there may be a time where one ore more of these is not required or available. One thing I found out is that if the element doesn\u2019t exist then grid will not create space for it. This may be obvious, but it can be really helpful in making a nice malleable component.\nWe have only looked at columns, as existing components have their own spacing for the vertical rhythm of the page we don\u2019t really want to have them take up equal space in the component and just take up the space as needed. We can do this by adding grid-auto-rows: min-content; to our .features. This is useful if you also need your component to take up a height that is more than the component itself.\nThe grid of the future\nFrom prototyping this new grid and components in CSS Grid, I\u2019ve found it a fantastic way to reimagine how we can create a layout or grid system for our sites. It gives us options to create the same layouts in differing ways that could suit a project and its needs.\nIt allows us to carry on \u2013 if we choose to \u2013 using a <div>-based grid but swapping out floats for CSS Grid or to tie it to our components so they have specific places to go depending on what component is being used. Or we could have several \u2018grid components\u2019 in our design system that we could use to layout various components throughout a page.\nIf you find yourself tasked with creating some new components for your design system try it. If you are starting from scratch I believe you really should start with CSS Grid for your layout.\nIt really feels like the possibilities are endless in terms of layout for the web.\nResources\nHere are just a few resources I have pawed over these last few weeks whilst getting acquainted with CSS Grid.\n\nA collection of CodePens from this article\nGrid by Example from Rachel Andrew\nA Complete Guide to CSS Grid on Codrops from Hui Jing Chen\nRachel Andrew\u2019s Blog Archive tagged: cssgrid\nCSS Grid Layout Examples\nMDN\u2019s CSS Grid Layout\nA Complete Guide to Grid from CSS-Tricks\nCSS Grid Layout Module Level 1 Specification", "year": "2017", "author": "Stuart Robson", "author_slug": "stuartrobson", "published": "2017-12-12T00:00:00+00:00", "url": "https://24ways.org/2017/design-systems-and-css-grid/", "topic": "code"}
{"rowid": 236, "title": "Extreme Design", "contents": "Recently, I set out with twelve other designers and developers for a 19th century fortress on the Channel Island of Alderney. We were going to /dev/fort, a sort of band camp for geeks. Our cohort\u2019s mission: to think up, build and finish something \u2013 without readily available internet access.\n\n Alderney runway, photo by Chris Govias\n\n\n\nWait, no internet?\n\nWell, pretty much. As the creators of /dev/fort James Aylett and Mark Norman Francis put it: \u201cImagine a place with no distractions \u2013 no IM, no Twitter\u201d. But also no way to quickly look up a design pattern, code sample or source material. Like packing for camping, /dev/fort means bringing everything you\u2019ll need on your back or your hard drive: from long johns to your favourite icon set.\n\nWe got to work the first night discussing ideas for what we wanted to build. By the time breakfast was cleared up the next morning, we\u2019d settled on Russ\u2019s idea to make the Apollo 13 (PDF) transcript accessible. Days two and three were spent collaboratively planning (KJ style) what features we wanted to build, and unravelling the larger UX challenges of the project. The next five days were spent building it. Within 36 hours of touchdown at Southampton Airport, we launched our creation: spacelog.org\n\nThe weather was cold, the coal fire less than ideal, food and supplies a hike away, and the process lightning-fast. A week of designing under extreme circumstances called for an extreme process. Some of this was driven by James\u2019s and Norm\u2019s experience running these things, but a lot of it materialised while we were there \u2013 especially for our three-strong design team (myself, Gavin O\u2019 Carroll and Chris Govias) who, though we knew each other, had never worked together as a group in this kind of scenario before.\n\nThe outcome was a pretty spectacular process, with a some key takeaways useful for any small group trying to build something quickly.\n\nWhat it\u2019s like inside the fort\n\n/dev/fort has the pressure and pace of a hack day without being a hack day \u2013 primarily, no workshops or interruptions\u201a but also a different mentality. While hack days are typically developer-driven with a \u2018hack first, design later (if at all)\u2019 attitude, James was quick to tell the team to hold off from writing any code until we had a plan. This put a healthy pressure on the design and product folks to slash through the UX problems before we started building.\n\nWhile the fort had definitely more of a hack day feel, all of us were familiar with Agile methods, so we borrowed a few useful techniques such as morning stand-ups and an emphasis on teamwork. We cut some really good features to make our launch date, and chunked the work based on user goals, iterating as we went.\n\nWhat made this design process work?\n\nA golden ratio of teams\n\nMy personal experience both professionally and in free-form situations like this, is a tendency to get/hire a designer. Leaders of businesses, founders of start-ups, organisers of events: one designer is not enough! Finding one ace-blooded designer who can \u2018do everything\u2019 will always result in bottleneck and burnout. Like the nuances between different development languages, design is a multifaceted discipline, and very few can claim to be equally strong in every aspect. Overlap in skill set will result in a stronger, more robust interface.\n\nMore importantly, however, having lots of designers to go around meant that we all had the opportunity to pair with developers, polishing the details that don\u2019t usually get polished. As soon as we launched, the public reception of the design and UX was overwhelmingly positive (proof!). But also, a lot of people asked us who the designer was, attributing it to one person.\n\nWhile it\u2019s important to note that everyone in our team was multitalented (and could easily shift between roles, helping us all stay unblocked), the golden ratio James and Norm devised was two product/developer folks, three interaction designers and eight developers.\n\n photo by Ben Firshman\n\nEquality inside the fortress walls\n\nSomething magical about the fort is how everyone leaves the outside world on the drawbridge. Job titles, professional status, Twitter followers, and so on. Like scout camp, a mutual respect and trust is expected of all the participants. Like extreme programming, extreme design requires us all to be equal partners in a collaborative team. I think this is especially worth noting for designers; our past is filled with the clear hierarchy of the traditional studio system which, however important for taste and style, seems less compatible with modern web/software development methods.\n\nBeing equal doesn\u2019t mean being the same, however. We established clear roles and teams for ourselves on the second day, deferring to that person when a decision needed to be made. As the interface coalesced, the designers and developers took ownership over certain parts to ensure the details got looked after, while staying open to ideas and revisions from the rest of the cohort.\n\nCreate a space where everyone who enters is equal, but be sure to establish clear roles. Even if it\u2019s just for a short while, the environment will be beneficial.\n\n photo by Ben Firshman\n\nHang your heraldry from the rafters\n\nForts and castles are full of lore: coats of arms; paintings of battles; suits of armour. It\u2019s impossible not to be surrounded by these stories, words and ways of thinking. Like the whiteboards on the walls, putting organisational lore in your physical surroundings makes it impossible not to see.\n\nRyan Alexander brought some of those static-cling whiteboard sheets which were quickly filled with use cases; IA; team roles; and, most importantly, a glossary. As soon as we started working on the project, we realised we needed to get clear on what certain words meant: what was a logline, a range, a phase, a key moment? Were the back-end people using these words in the same way design and product was? Quickly writing up a glossary of terms meant everyone was instantly speaking the same language. There was no \u201cAh, I misunderstood because in the data structure x means y\u201d or, even worse, accidental seepage of technical language into the user interface copy.\n\nPut a glossary of your internal terminology somewhere big and fat on the wall. Stand around it and argue until you agree on what it says. Leave it up; don\u2019t underestimate the power of ambient communication and physical reference.\n\nPlan more, download less\n\nWhile internet is forbidden inside the fort, we did go on downloading expeditions: NASA photography; code documentation; and so on. The project wouldn\u2019t have been possible without a few trips to the web. We had two lists on the wall: groceries and supplies; internets \u2013 \u201cloo roll; Tom Stafford photo\u201c.\n\nThis changed our usual design process, forcing us to plan carefully and think of what we needed ahead of time. Getting to the internet was a thirty-minute hike up a snow covered cliff to the town airport, so you really had to need it, too. \n\n The path to the internet\n\nFor the visual design, especially, this resulted in more focus up front, and communication between the designers on what assets we required. It made us make decisions earlier and stick with them, creating less distraction and churn later in the process. \n\nTry it at home: unplug once you\u2019ve got the things you need. As an artist, it\u2019s easier to let your inner voice shine through if you\u2019re not looking at other people\u2019s work while creating.\n\nSocial design\n\nFinally, our design team experimented with a collaborative approach to wireframing. Once we had collectively nailed down use cases, IA, user journeys and other critical artefacts, we tried a pairing approach. One person drew in Illustrator in real time as the other two articulated what to draw. (This would work equally well with two people, but with three it meant that one of us could jump up and consult the lore on the walls or clarify a technical detail.) The result: we ended up considering more alternatives and quickly rallying around one solution, and resolved difficult problems more quickly.\n\nAt a certain stage we discovered it was more efficient for one person to take over \u2013 this happened around the time when the basic wireframes existed in Illustrator and we\u2019d collectively run through the use cases, making sure that everything was accounted for in a broad sense. At this point, take a break, go have a beer, and give yourself a pat on the back.\n\nPut the files somewhere accessible so everyone can use them as their base, and divide up the more detailed UI problems, screens or journeys. At this level of detail it\u2019s better to have your personal headspace.\n\nGavin called this \u2018social design\u2019. Chatting and drawing in real time turned what was normally a rather solitary act into a very social process, with some really promising results. I\u2019d tried something like this before with product or developer folks, and it can work \u2013 but there\u2019s something really beautiful about switching places and everyone involved being equally quick at drawing. That\u2019s not something you get with non-designers, and frequent swapping of the \u2018driver\u2019 and \u2018observer\u2019 roles is a key aspect to pairing.\n\nTackle the forest collectively and the trees individually \u2013 it will make your framework more robust and your details more polished. Win/win. \n\nThe return home\n\nGrateful to see a 3G signal on our phones again, our flight off the island was delayed, allowing for a flurry of domain name look-ups, Twitter catch-up, and e-mails to loved ones. A week in an isolated fort really made me appreciate continuous connectivity, but also just how unique some of these processes might be. \n\nYou just never know what crazy place you might be designing from next.", "year": "2010", "author": "Hannah Donovan", "author_slug": "hannahdonovan", "published": "2010-12-09T00:00:00+00:00", "url": "https://24ways.org/2010/extreme-design/", "topic": "process"}
{"rowid": 73, "title": "How to Make Your Site Look Half-Decent in Half an Hour", "contents": "Programmers like me are often intimidated by design \u2013 but a little effort can give a huge return on investment. Here are one coder\u2019s tips for making any site quickly look more professional. \n\nI am a programmer. I am not a designer. I have a degree in computer science, and I don\u2019t mind Comic Sans. (It looks cheerful. Move on.)\n\nBut 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\u2019t think a site is credible unless it also looks attractive.\n\nFor a very long time after I became a programmer, I was scared of design. Design seemed to consist of complicated rules that weren\u2019t written down anywhere, plus an unlearnable sense of taste, possessed only by a black-clad elite. \n\nBut 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\u2019t come close to the effect a professional designer could achieve, gathering these resources for improving a site\u2019s look and feel has been really helpful. \n\nIf I hadn\u2019t figured out some basic design shortcuts, it\u2019s 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\u2019t reach the audience they deserve, simply because their design doesn\u2019t match their execution. \n\nSo, 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.\n\nOne 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. \n\nIf you are a designer, I would love to hear your suggestions for the best tools that I\u2019ve missed, and I\u2019d love to know how we programmers can do things better.\n\nWith that, on to the tools\u2026\n\n1. Use Bootstrap\n\nIf you\u2019re 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. \n\nEssentially, 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. \n\nAnother massive upside is that it makes it easy to make any site responsive, so you don\u2019t 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.  \n\nIf you have more time, then Mark Otto\u2019s article on why and how Bootstrap was created at Twitter is well worth a read. \n\n2. Pimp Bootstrap\n\nUsing 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\u2019s known. \n\nIf you\u2019re 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\u2019t achieve ourselves. Your site won\u2019t be unique, but it will look good quickly. \n\nLuckily, it\u2019s pretty easy to make Bootstrap not look too much like Bootstrap \u2013 using fonts, CSS effects, background images, colour schemes and so on. Most of the rest of this article covers different ways to achieve this. \n\nWe are going to customize this Bootstrap example page.\n\nThis already has some custom CSS in the <head>. We\u2019ll pull it all out, and create a new CSS file, custom.css. Then we add a reference to it in the header. Now we\u2019re ready to start customizing things.\n\n\n\n3. Fonts\n\nWeb fonts are one of the quickest ways to make your site look distinctive, modern, and less Bootstrappy, so we\u2019ll start there. \n\nFirst, 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\u2019re going to use one of DesignShack\u2019s suggested free Google Fonts pairings. Our fonts are Corben (for headings) and Nobile (for body copy). \n\nThen we add these files to our <head>. \n\n<link href=\"http://fonts.googleapis.com/css?family=Corben:bold\" rel=\"stylesheet\" type=\"text/css\">\n <link href=\"http://fonts.googleapis.com/css?family=Nobile\" rel=\"stylesheet\" type=\"text/css\">\n\n\u2026and this to custom.css: \n\nh1, h2, h3, h4, h5, h6 {\n    font-family: 'Corben', Georgia, Times, serif;\n}\np, div {\n    font-family: 'Nobile', Helvetica, Arial, sans-serif;\n}\n\nNow our example looks like this. It\u2019s not going to win any design awards, but it\u2019s immediately better:\n\n\n\nI also recommend the web font services Fontdeck, or Typekit \u2013 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\u2019s post is worth a read. \n\n4. Textures\n\nAn instant way to make a site look classy is to use textures. You know the grey, stripy, indefinably elegant background on 24ways.org? That.\n\nIf only there was a superb resource listing attractive, free, ready-to-use textures\u2026 Oh wait, there\u2019s Atle Mo\u2019s Subtle Patterns. \n\nWe\u2019re 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:\n\nbody { \n    background: url(/img/cream_dust.png) repeat 0 0;\n}\n\nBang:\n\n\n\nFor some design background on patterns, I recommend reading through Smashing Magazine\u2019s guidelines on textures. (TL;DR version: use textures to enhance beauty, and clarify the information architecture of your site; but don\u2019t overdo it, or inadvertently obscure your text.)\n\nStill more to do, though. Onwards. \n\n5. Icons\n\nLast year\u2019s 24 ways taught us to use icon fonts for our site icons. \n\nThis is great for the time-pressed coder, because icon fonts don\u2019t just cut down on HTTP requests \u2013 they\u2019re a lot quicker to set up than image-based icons, too. \n\nBootstrap 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\u2019re not going to bother here). \n\nTo 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:\n\n<link rel=\"stylesheet\" href=\"/css/font-awesome.css\">\n\nFinally, we\u2019ll add a truck icon to the main action button, as follows. Why a truck? Why not?\n\n<a class=\"btn btn-large btn-success\" href=\"#\"><i class=\"icon-truck\"></i> Sign up today</a>\n\nWe\u2019ll also tweak our CSS file to stop the icon nudging up against the button text:\n\n.jumbotron .btn i { \n    margin-right: 8px;  \n}\n\nAnd this is how it looks:\n\n\n\nNot 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. \n\nIf you\u2019d 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\u2019t work in IE7. \n\n6. CSS3\n\nThe next thing you could do is add some CSS3 goodness. It can really help the key elements of the site stand out. \n\nIf you are pressed for time, just adding box-shadow and text-shadow to emphasize headings and standouts can be useful: \n\nh1 { \n    text-shadow: 1px 1px 1px #ccc;\n}\n.div-that-you want-to-stand-out { \n    box-shadow: 0 0 1em 1em #ccc;\n}\n\nWe have a little more time though, so we\u2019re going to do something more subtle. We\u2019ll add a radial gradient behind the main heading, using an online gradient editor. \n\nThe 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: \n\n<!--[if gte IE 9]>\n  <style type=\"text/css\">\n    .gradient {\n       filter: none;\n    }\n  </style>\n<![endif]-->\n\nAnd the effect \u2013 I don\u2019t know what a designer would think, but I like the way it makes the heading pop.\n\n\n\nFor a crash course in useful modern CSS effects, I highly recommend CodeSchool\u2019s online course in Functional HTM5 and CSS3. It costs money ($25 a month to subscribe), but it\u2019s worth it for the time you\u2019ll save. As a bonus, you also get access to some excellent JavaScript, Ruby and GitHub courses. \n\n(Incidentally, if you find yourself fighting with basic float and display attributes in CSS \u2013 and there\u2019s no shame in it, CSS layout is not intuitive \u2013 I recommend the CSS Cross-Country course at CodeSchool.)\n\n7. Add a twist\n\nWe could leave it there, but we\u2019re going to add a background image, and give the site some personality. \n\nThis is the area of design that I think many programmers find most intimidating. How do we create the graphics and photographs that a designer would use? The answer is iStockPhoto and its competitors \u2013 online image libraries where you can find and pay for images. They won\u2019t be unique, but for our purposes, that\u2019s fine. \n\nWe\u2019re going to use a Christmassy image. For a twist, we\u2019re going to use Backstretch to make it responsive. \n\nWe must pay for the image, then download it to our /img/ directory. Then, we set it as our <body>\u2019s background-image, by including a JavaScript file with just the following line: \n\n$.backstretch(\"/img/winter.jpg\");\n\nWe 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:\n\n.container-narrow {\n    background: url(/img/cream_dust_transparent.png) repeat 0 0;\n}\n\nWe also fiddle with the padding on body and .container-narrow a bit, and this is the result: \n\n\n\n(Aside: If this were a real site, I\u2019d want to buy images in multiple sizes and ensure that Backstretch chose the most appropriately sized image for our screen, perhaps using responsive images.)\n\nHow 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. \n\n8. Colour schemes\n\nWe\u2019re just about getting there \u2013 though we\u2019re probably past half an hour now \u2013 but that button and that menu still both look awfully Bootstrappy. \n\nReal sites, with real designers, have a colour palette, carefully chosen to harmonize and match the brand profile. For our purposes, we\u2019re just going to borrow some colours from the image. We use Gimp\u2019s 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. \n\nFinally, 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\u2019t paste it all here, but you can find it in the CSS file. \n\nWe also reset the colour of the pills in the navigation menu, which is a bit easier: \n\n.nav-pills > .active > a, .nav-pills > .active > a:hover {\n    background-color: #FF9473;\n}\n\nI\u2019m not sure if the result is great to be honest, but at least we\u2019ve lost those Bootstrap-blue buttons:\n\n\n\nAnother way to do it, if you didn\u2019t 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. \n\nThe key thing is to find a palette with an open licence, so you can legitimately use it. Unfortunately, you can\u2019t search for palettes by licence type, but many do have open licences. Here\u2019s a popular palette with a CC-BY-SA licence that allows reuse with attribution.  \n\nAs above, you can use the hex values from the palette in your custom CSS, and bask in the newly colourful results.\n\n9. Read on\n\nWith the above techniques, you can make a site that is starting to look slightly more professional, pretty quickly. \n\nIf you have the time to invest, it\u2019s 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\u2019s Design for Hackers: Reverse-Engineering Beauty, which explains the basic principles behind choosing colours, fonts, typefaces and layout.\n\nIn the introduction to his book, David writes: \n\n\n\tNo group stands to gain more from design literacy than hackers do\u2026 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.\n\n\nWell said. If you have half a day to invest, rather than half an hour, I recommend getting hold of David\u2019s book.\n\nAnd 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.", "year": "2012", "author": "Anna Powell-Smith", "author_slug": "annapowellsmith", "published": "2012-12-16T00:00:00+00:00", "url": "https://24ways.org/2012/how-to-make-your-site-look-half-decent/", "topic": "design"}
{"rowid": 151, "title": "Get In Shape", "contents": "Pop quiz: what\u2019s wrong with the following navigation?\n\n\n\nMaybe nothing. But then again, maybe there\u2019s something bugging you about the way it comes together, something you can\u2019t quite put your finger on. It seems well-designed, but it also seems a little\u2026 off.\n\nThe design decisions that led to this eventual form were no doubt well-considered:\n\n\n\tClient: The top level needs to have a \u201ccurrent page\u201d status indicator of some sort.\n\tDesigner: How about a white tab?\n\tClient: Great! The second level needs to show up underneath the first level though\u2026\n\tDesigner: Okay, but that white tab I just added makes it hard to visually connect the bottom nav to the top.\n\tClient: Too late, we\u2019ve seen the white tab and we love it. Try and make it work.\n\tDesigner: Right. So I placed the second level in its own box.\n\tClient: Hmm. They seem too separated. I can\u2019t tell that the yellow nav is the second level of the first.\n\tDesigner: How about an indicator arrow?\n\tClient: Brilliant!\n\n\nThe problem is that the end result feels awkward and forced. During the design process, little decisions were made that ultimately affect the overall shape of the navigation. What started out as a neatly contained rounded rectangle ended up as an ambiguous double shape that looks funny, though it\u2019s often hard to pinpoint precisely why.\n\nThe Shape of Things\n\nWell the why in this case is because seemingly unrelated elements in a design still end up visually interacting. Adding a new item to a page impacts everything surrounding it. In this navigation example, we\u2019re looking at two individual objects that are close enough to each other that they form a relationship; if we reduce them to strictly their outlines, it\u2019s a little easier to see that this particular combination registers oddly.\n\n\n\nThe two shapes float with nothing really grounding them. If they were connected, perhaps it would be a different story. The white tab divides the top shape in half, leaving a gap in the middle of it. There\u2019s very little balance in this pairing because the overall shape of the navigation wasn\u2019t considered during the design process.\n\nHere\u2019s another example: Gmail. Great email client, but did you ever closely look at what\u2019s going on in that left hand navigation? The continuous blue bar around the message area spills out into the navigation. If we remove all text, we\u2019re left with this odd configuration:\n\n\n\nThough the reasoning for anchoring the navigation highlight against the message area might be sound, the result is an irregular shape that doesn\u2019t correspond with anything in reality. You may never consciously notice it, but once you do it\u2019s hard to miss. One other example courtesy of last.fm:\n\n\n\nThe two header areas are the same shade of pink so they appear to be closely connected. When reduced to their outlines it\u2019s easy to see that this combination is off-balance: the edges don\u2019t align, the sharp corners of the top shape aren\u2019t consistent with the rounded corners of the bottom, and the part jutting out on the right of the bottom one seems fairly random. The result is a duo of oddly mis-matched shapes.\n\nDesign Strategies\n\nOur minds tend to pick out familiar patterns. A clever designer can exploit this by creating references in his or her work to shapes and combinations with which viewers are already familiar. There are a few simple ideas that can be employed to help you achieve this: consistency, balance, and completion.\n\nConsistency\n\nA fairly simple way to unify the various disparate shapes on a page is by designing them with a certain amount of internal consistency. You don\u2019t need to apply an identical size, colour, border, or corner treatment to every single shape; devolving a design into boring repetition isn\u2019t what we\u2019re after here. But it certainly doesn\u2019t hurt to apply a set of common rules to most shapes within your work.\n\n\n\nConsider purevolume and its multiple rounded-corner panels. From the bottom of the site\u2019s main navigation to the grey \u201cExtras\u201d panels halfway down the page (shown above), multiple shapes use a common border radius for unity. Different colours, different sizes, different content, but the consistent outlines create a strong sense of similarity. Not that every shape on the site follows this rule; they break the pattern right at the top with a darker sharp-cornered header, and again with the thumbnails below. But the design remains unified, nonetheless.\n\nBalance\n\nArguably the biggest problem with the last.fm example earlier is one of balance. The area poking out of the bottom shape created a fairly obvious imbalance for no apparent reason. The right hand side is visually emphasized due to the greater area of pink coverage, but with the white gap left beside it, the emphasis seems unwarranted. It\u2019s possible to create tension in your design by mismatching shapes and throwing off the balance, but when that happens unintentionally it can look like a mistake.\n\n\n\nAbove are a few examples of design elements in balanced and unbalanced configurations. The examples in the top row are undeniably more pleasing to the eye than those in the bottom row. If these were fleshed out into full designs, those derived from the templates in the top row would naturally result in stronger work.\n\nTake a look at the header on 9Rules for a study in well-considered balance. On the left you\u2019ll see a couple of paragraphs of text, on the right you have floating navigational items, and both flank the site\u2019s logo. This unusual layout combines multiple design elements that look nothing alike, and places them together in a way that anchors each so that no one weighs down the header.\n\nCompletion\n\nAnd finally we come to the idea of completion. Shapes don\u2019t necessarily need hard outlines to be read visually as shapes, which can be exploited for various purposes. Notice how Zend\u2019s mid-page \u201cBusiness Topics\u201d and \u201cNews\u201d items (below) fade out to the right and bottom, but the placement of two of these side-by-side creates an impression of two panels rather than three disparate floating columns. By allowing the viewer\u2019s eye to complete the shapes, they\u2019ve lightened up the design of the page and removed inessential lines. In a busy design this technique could prove quite handy.\n\n\n\nAlong the same lines, the individual shapes within your design may also be combined visually to form outlines of larger shapes. The differently-coloured header and main content/sidebar shapes on Veerle\u2019s blog come together to form a single central panel, further emphasized by the slight drop shadow to the right.\n\nImplementation\n\nStudying how shape can be used effectively in design is simply a starting point. As with all things design-related, there are no hard and fast rules here; ultimately you may choose to bring these principles into your work more often, or break them for effect. But understanding how shapes interact within a page, and how that effect is ultimately perceived by viewers, is a key design principle you can use to impress your friends.", "year": "2007", "author": "Dave Shea", "author_slug": "daveshea", "published": "2007-12-16T00:00:00+00:00", "url": "https://24ways.org/2007/get-in-shape/", "topic": "design"}
{"rowid": 203, "title": "Jobs-to-Be-Done in Your UX Toolbox", "contents": "Part 1: What is JTBD?\nThe concept of a \u201cjob\u201d in \u201cJobs-To-Be-Done\u201d is neatly encapsulated by a oft-quoted line from Theodore Levitt:\n\n\u201cPeople want a quarter-inch hole, not a quarter inch drill\u201d.\n\nEven so, Don Norman pointed out that perhaps Levitt \u201cstopped too soon\u201d at what the real customer goal might be. In the \u201cThe Design of Everyday Things\u201d, he wrote:\n\n\u201cLevitt\u2019s example of the drill implying that the goal is really a hole is only partially correct, however. When people go to a store to buy a drill, that is not their real goal. But why would anyone want a quarter-inch hole? Clearly that is an intermediate goal. Perhaps they wanted to hang shelves on the wall. Levitt stopped too soon. Once you realize that they don\u2019t really want the drill, you realize that perhaps they don\u2019t really want the hole, either: they want to install their bookshelves. Why not develop methods that don\u2019t require holes? Or perhaps books that don\u2019t require bookshelves.\u201d\n\nIn other words, a \u201cjob\u201d in JTBD lingo is a way to express a user need or provide a customer-centric problem frame that\u2019s independent of a solution. As Tony Ulwick says:\n\n\u201cA job is stable, it doesn\u2019t change over time.\u201d\n\nAn example of a job is \u201ctiding you over from breakfast to lunch.\u201d You could hire a donut, a flapjack or a banana for that mid-morning snack\u2014whatever does the job. If you can arrive at a clearly identified primary job (and likely some secondary ones too), you can be more creative in how you come up with an effective solution while keeping the customer problem in focus.\nThe team at Intercom wrote a book on their application of JTBD. In it, Des Traynor cleverly characterised how JTBD provides a different way to think about solutions that compete for the same job:                                \n\n\u201cEconomy travel and business travel are both capable candidates applying for [the job: Get me face-to-face with my colleague in San Francisco], though they\u2019re looking for significantly different salaries. Video conferencing isn\u2019t as capable, but is willing to work for a far smaller salary. I\u2019ve a hiring choice to make.\u201d\n\nSo far so good: it\u2019s relatively simple to understand what a job is, once you understand how it\u2019s different from a \u201ctask\u201d.  Business consultant and Harvard professor Clay Christensen talks about the concept of \u201chiring\u201d a product to do a \u201cjob\u201d, and firing it when something better comes along. If you\u2019re a company that focuses solutions on the customer job, you\u2019re more likely to succeed. You\u2019ll find these concepts often referred to as \u201cJobs-to-be-Done theory\u201d. But the application of Jobs-to-Be-Done theory is a little more complicated; it comprises several related approaches.\nI particularly like Jim Kalbach\u2019s description of how JTBD is a \u201clens through which to understand value creation\u201d. But it is also more. In my view, it\u2019s a family of frameworks and methods\u2014and perhaps even a philosophy.\nDifferent facets in a family of frameworks\nJTBD has its roots in market research and business strategy, and so it comes to the research table from a slightly different place compared to traditional UX or design research\u2014we have our roots in human-computer interaction and ergonomics. I\u2019ve found it helpful to keep in mind is that the application of JTBD theory is an evolving beast, so it\u2019s common to find contradictions across different resources. My own use of it has varied from project to project. In speaking to others who have adopted it in different measures, it seems that we have all applied it in somewhat multifarious ways. As we like to often say in interviews: there are no wrong answers.\nOutcome Driven Innovation\nTony Ulwick\u2019s version of the JTBD history began with Outcome Driven Innovation (ODI), and this approach is best outlined in his seminal article published in the Harvard Business Review in 2002.  To understand his more current JTBD approach in his new book \u201cJobs to Be Done: Theory to Practice\u201d, I actually found it beneficial to read his approach in the original 2002 article for a clearer reference point.\nIn the earlier article, Ulwick presented a rigorous approach that combines interviews, surveys and an \u201copportunity\u201d algorithm\u2014a sequence of steps to determine the business opportunity. ODI centres around working with \u201cdesired outcome statements\u201d that you unearth through interviews, followed by a means to quantify the gap between importance and satisfaction in a survey to different types of customers.  \nSince 2008, Ulwick has written about using job maps to make sense of what the customer may be trying to achieve. In a recent article, he describes the aim of the activity is \u201cto discover what the customer is trying to get done at different points in executing a job and what must happen at each juncture in order for the job to be carried out successfully.\u201d\nA job map is not strictly a journey map, however tempting it is to see it that way. From a UX perspective, is one of many models we can use\u2014and as our research team at Clearleft have found, how we use model can depend on the nature of the jobs we\u2019ve uncovered in interviews and the characteristics of the problem we\u2019re attempting to solve.\nFigure 1. Universal job map\nUlwick\u2019s current methodology is outlined in his new book, where he describes a complete end-to-end process: from customer and competitor research to framing market and product strategy.\nThe Jobs-To-Be-Done Interview\nBack in 2013, I attended a workshop by Chris Spiek and Bob Moesta from the ReWired Group on JTBD at the behest of a then-MailChimp colleague, and I came away excited about their approach to product research. It felt different from anything I\u2019d done before and for the first time in years, I felt that I was genuinely adding something new to my research toolbox.\nA key idea is that if you focus on the stories of those who switched to you, and those who switch away from you, you can uncover the core jobs through looking at these opposite ends of engagement.\nThis framework centres around the JTBD interview method, which harnesses the power of a narrative framework to elicit the real reasons why someone \u201chired\u201d something to do a job\u2014be it something physical like a new coffee maker, or a digital service, such as a to-do list app. As you interview, you are trying to unearth the context around the key moments on the JTBD timeline (Figure 2). A common approach is to begin from the point the customer might have purchased something, back to the point where the thought of buying this thing first occurred to them.\nFigure 2. JTBD Timeline\nFigure 3. The Four Forces\nThe Forces Diagram (Figure 3) is a post-interview analysis tool where you can map out what causes customers to switch to something new and what holds them back.\nThe JTBD interview is effective at identifying core and secondary jobs, as well as some context around the user need. Because this method is designed to extract the story from the interviewee, it\u2019s a powerful way to facilitate recall. Having done many such interviews, I\u2019ve noticed one interesting side effect: participants often remember more details later on after the conversation has formally ended. It is worth scheduling a follow-up phone call or keep the channels open.\nStrengths aside, it\u2019s good to keep in mind that the JTBD interview is still primarily an interview technique, so you are relying on the context from the interviewee\u2019s self-reported perspective. For example, a stronger research methodology combines JTBD interviews with contextual research and quantitative methods.  \nJob Stories\nAlan Klement is credited for coming up with the term \u201cjob story\u201d to describe the framing of jobs for product design by the team at Intercom:\n\n\u201cWhen \u2026 I want to \u2026 so I can \u2026.\u201d\n\nFigure 4. Anatomy of a Job Story\nUnlike a user story that traditionally frames a requirement around personas, job stories frame the user need based on the situation and context. Paul Adams, the VP of Product at Intercom, wrote:\n\n\u201cWe frame every design problem in a Job, focusing on the triggering event or situation, the motivation and goal, and the intended outcome. [\u2026] We can map this Job to the mission and prioritise it appropriately. It ensures that we are constantly thinking about all four layers of design. We can see what components in our system are part of this Job and the necessary relationships and interactions required to facilitate it. We can design from the top down, moving through outcome, system, interactions, before getting to visual design.\u201d\n\nSystems of Progress\nApart from advocating using job stories, Klement believes that a core tenet of applying JTBD revolves around our desire for \u201cself-betterment\u201d\u2014and that focusing on everyone\u2019s desire for self-betterment is core to a successful strategy.\nIn his book, Klement takes JTBD further to being a tool for change through applying systems thinking. There, he introduces the systems of progress and how it can help focus product strategy approach to be more innovative.\nCoincidentally, I applied similar thinking on mapping systemic change when we were looking to improve users\u2019 trust with a local government forum earlier this year. It\u2019s not just about capturing and satisfying the immediate job-to-be-done, it\u2019s about framing the job so that you can a clear vision forward on how you can help your users improve their lives in the ways they want to.\nThis is really the point where JTBD becomes a philosophy of practice.\nPart 2: Mixing It Up\nThere has been some misunderstanding about how adopting JTBD means ditching personas or some of our existing design tools or research techniques. This couldn\u2019t have been more wrong.\nFigure 5: Jim Kalbach\u2019s JTBD model\nJim Kalbach has used Outcome-Driven Innovation for around 10 years. In a 2016 article, he presents a synthesised model of how to think about that has key elements from ODI, Christensen\u2019s theories and the structure of the job story.\nMore interestingly, Kalbach has also combined the use of mental models with JTBD.\nClaire Menke of UDemy has written a comprehensive article about using personas, JTBD and customer journey maps together in order to communicate more complete story from the users\u2019 perspective. Claire highlights an especially interesting point in her article as she described her challenges:\n\u201cAfter much trial and error, I arrived at a foundational research framework to suit every team\u2019s needs \u2014 allowing everyone to share the same holistic understanding, but extract the type of information most applicable to their work.\u201d\nIn other words, the organisational context you are in likely can dictate what works best\u2014after all the goal is to arrive at the best user experience for your audiences. Intercom can afford to go full-on on applying JTBD theory as a dominant approach because they are a start-up, but a large company or organisation with multiple business units may require a mix of tools, outputs and outcomes.\nJTBD is an immensely powerful approach on many fronts\u2014you\u2019ll find many different references that lists the ways you can apply JTBD. However, in the context of this discussion, it might also be useful to we examine where it lies in our models of how we think about our UX and product processes.\nJTBD in the UX ecosystem\nFigure 6. The Elements of User Experience (source)\nThere are many ways we have tried to explain the UX discipline but I think Jesse James Garrett\u2019s Elements of User Experience is a good place to begin.\nI sometimes also use little diagram to help me describe the different levels you might work at when you work through the complexity of designing and developing a product. A holistic UX strategy needs to address all the different levels for a comprehensive experience: your individual product UI, product features, product propositions and brand need to have a cohesive definition.\nFigure 7. Which level of product focus?\nWe could, of course, also think about where it fits best within the double diamond.\nAgain, bearing in mind that JTBD has its roots in business strategy and market research, it is excellent at clarifying user needs, defining high-level specifications and content requirements. It is excellent for validating brand perception and value proposition \u2014all the way down to your feature set. In other words, it can be extremely powerful all the way through to halfway of the second diamond. You could quite readily combine the different JTBD approaches because they have differences as much as overlaps. However, JTBD generally starts getting a little difficult to apply once we get to the details of UI design.\nThe clue lies in JTBD\u2019s raison d\u2019\u00eatre: a job statement is solution independent. Hence, once we get to designing solutions, we potentially fall into a existential black hole.\nThat said, Jim Kalbach has a quick case study on applying JTBD to content design tucked inside the main article on a synthesised JTBD model. Alan Klement has a great example of how you could use UI to resolve job stories. You\u2019ll notice that the available language of \u201cjobs\u201d drops off at around that point.\nJob statements and outcome statements provide excellent \u201cmini north-stars\u201d as customer-oriented focal points, but purely satisfying these statements would not necessarily guarantee that you have created a seamless and painless user experience.\nPlaying well with others\nYou will find that JTBD plays well with Lean, and other strategy tools like the Value Proposition Canvas. With every new project, there is potential to harness the power of JTBD alongside our established toolbox.\nWhen we need to understand complex contexts where cultural or socioeconomic considerations have to be taken into account, we are better placed with combining JTBD with more anthropological approaches. And while we might be able to evaluate if our product, website or app satisfies the customer jobs through interviews or surveys, without good old-fashioned usability testing we are unlikely to be able to truly validate why the job isn\u2019t being represented as it should. In this case, individual jobs solved on the UI can be set up as hypotheses to be proven right or wrong. \nThe application of Jobs-to-be-Done is still evolving. I\u2019ve found it to be very powerful and I struggle to remember what my UX professional life was like before I encountered it\u2014it has completely changed my approach to research and design.\nThe fact JTBD is still evolving as a practice means we need to be watchful of dogma\u2014there\u2019s no right way to get a UX job done after all, it nearly always depends. At the end of the day, isn\u2019t it about having the right tool for the right job?", "year": "2017", "author": "Steph Troeth", "author_slug": "stephtroeth", "published": "2017-12-04T00:00:00+00:00", "url": "https://24ways.org/2017/jobs-to-be-done-in-your-ux-toolbox/", "topic": "ux"}
{"rowid": 115, "title": "Charm Clients, Win Pitches", "contents": "Over the years I have picked up a number of sales techniques that have lead to us doing pretty well in the pitches we go for. Of course, up until now, these top secret practices have remained firmly locked in the company vault but now I am going to share them with you. They are cunningly hidden within the following paragraphs so I\u2019m afraid you\u2019re going to have to read the whole thing.\n\nOk, so where to start? I guess a good place would be getting invited to pitch for work in the first place.\n\nShameless self promotion\n\nWhat not to do\n\nYou\u2019re as keen as mustard to \u2018sell\u2019 what you do, but you have no idea as to the right approach. From personal experience (sometimes bitter!), the following methods are as useful as the proverbial chocolate teapot:\n\n\n\tCold calling\n\tAdvertising\n\tBidding websites\n\tSales people\n\tNetworking events\n\n\nOk, I\u2019m exaggerating; sometimes these things work. For example, cold calling can work if you have a story \u2013 a reason to call and introduce yourself other than \u201cwe do web design and you have a website\u201d. \u201cWe do web design and we\u2019ve just moved in next door to you\u201d would be fine. \n\nAdvertising can work if your offering is highly specialist. However, paying oodles of dollars a day to Google Ads to appear under the search term \u2018web design\u2019 is probably not the best use of your budget. \n\nSpecialising is, in fact, probably a good way to go. Though it can feel counter intuitive in that you are not spreading yourself as widely as you might, you will eventually become an expert and therefore gain a reputation in your field. Specialism doesn\u2019t necessarily have to be in a particular skillset or technology, it could just as easily be in a particular supply chain or across a market.\n\nTarget audience\n\n\u2018Who to target?\u2019 is the next question. If you\u2019re starting out then do tap-up your family and friends. Anything that comes your way from them will almost certainly come with a strong recommendation. Also, there\u2019s nothing wrong with calling clients you had dealings with in previous employment (though beware of any contractual terms that may prevent this). You are informing your previous clients that your situation has changed; leave it up to them to make any move towards working with you. After all, you\u2019re simply asking to be included on the list of agencies invited to tender for any new work.\n\nLook to target clients similar to those you have worked with previously. Again, you have a story \u2013 hopefully a good one!\n\nSo how do you reach these people?\n\n\n\tMailing lists\n\tForums\n\tWriting articles\n\tConferences / Meetups\n\tSpeaking opportunities\n\tSharing Expertise\n\n\nIn essence: blog, chat, talk, enthuse, show off (a little)\u2026 share.\n\nThere are many ways you can do this. There\u2019s the traditional portfolio, almost obligatory blog (regularly updated of course), podcast, \u2018giveaways\u2019 like Wordpress templates, CSS galleries and testimonials. Testimonials are your greatest friend. Always ask clients for quotes (write them and ask for their permission to use) and even better, film them talking about how great you are.\n\nFinally, social networking sites can offer a way to reach your target audiences. You do have to be careful here though. You are looking to build a reputation by contributing value. Do not self promote or spam!\n\nWriting proposals\n\nIs it worth it?\n\nOk, so you have been invited to respond to a tender or brief in the form of a proposal. Good proposals take time to put together so you need to be sure that you are not wasting your time. There are two fundamental questions that you need to ask prior to getting started on your proposal:\n\n\n\tCan I deliver within the client\u2019s timescales?\n\tDoes the client\u2019s budget match my price?\n\n\nThe timescales that clients set are often plucked from the air and a little explanation about how long projects usually take can be enough to change expectations with regard to delivery. However, if a deadline is set in stone ask yourself if you can realistically meet it. Agreeing to a deadline that you know you cannot meet just to win a project is a recipe for an unhappy client, no chance of repeat business and no chance of any recommendations to other potential clients.\n\nPrice is another thing altogether. So why do we need to know?\n\nThe first reason, and most honest reason, is that we don\u2019t want to do a lot of unpaid pitch work when there is no chance that our price will be accepted. Who would? But this goes both ways \u2013 the client\u2019s time is also being wasted. It may only be the time to read the proposal and reject it, but what if all the bids are too expensive? Then the client needs to go through the whole process again.\n\nThe second reason why we need to know budgets relates to what we would like to include in a proposal over what we need to include. For example, take usability testing. We always highly recommend that a client pays for at least one round of usability testing because it will definitely improve their new site \u2013 no question. But, not doing it doesn\u2019t mean they\u2019ll end up with an unusable turkey. It\u2019s just more likely that any usability issues will crop up after launch.\n\nI have found that the best way to discover a budget is to simply provide a ballpark total, usually accompanied by a list of \u2018likely tasks for this type of project\u2019, in an initial email or telephone response. Expect a lot of people to dismiss you out of hand. This is good. Don\u2019t be tempted to \u2018just go for it\u2019 anyway because you like the client or work is short \u2013 you will regret it.\n\nOthers will say that the ballpark is ok. This is not as good as getting into a proper discussion about what priorities they might have but it does mean that you are not wasting your time and you do have a chance of winning the work. The only real risk with this approach is that you misinterpret the requirements and produce an inaccurate ballpark.\n\nFinally, there is a less confrontational approach that I sometimes use that involves modular pricing. We break down our pricing into quite detailed tasks for all proposals but when I really do not have a clue about a client\u2019s budget, I will often separate pricing into \u2018core\u2019 items and \u2018optional\u2019 items. This has proved to be a very effective method of presenting price.\n\nWhat to include\n\nSo, what should go into a proposal? It does depend on the size of the piece of work. If it\u2019s a quick update for an existing client then they don\u2019t want to read through all your blurb about why they should choose to work with you \u2013 a simple email will suffice.\n\nBut, for a potential new client I would look to include the following:\n\n\n\tYour suitability\n\tSummary of tasks\n\tTimescales\n\tProject management methodology\n\tPricing\n\tTesting methodology\n\tHosting options\n\tTechnologies\n\tImagery\n\tReferences\n\tFinancial information\n\tBiographies\n\n\nHowever, probably the most important aspect of any proposal is that you respond fully to the brief. In other words, don\u2019t ignore the bits that either don\u2019t make sense to you or you think irrelevant. If something is questionable, cover it and explain why you don\u2019t think it is something that warrants inclusion in the project.\n\nShould you provide speculative designs? If the brief doesn\u2019t ask for any, then certainly not. If it does, then speak to the client about why you don\u2019t like to do speculative designs. Explain that any designs included as part of a proposal are created to impress the client and not the website\u2019s target audience. Producing good web design is a partnership between client and agency. This can often impress and promote you as a professional. However, if they insist then you need to make a decision because not delivering any mock-ups will mean that all your other work will be a waste of time.\n\nWalking away\n\nAs I have already mentioned, all of this takes a lot of work. So, when should you be prepared to walk away from a potential job? I have already covered unrealistic deadlines and insufficient budget but there are a couple of other reasons. Firstly, would this new client damage your reputation, particularly within current sectors you are working in? Secondly, can you work with this client? A difficult client will almost certainly lead to a loss-making project.\n\nPerfect pitch\n\nRequirements\n\nIf the original brief didn\u2019t spell out what is expected of you at a presentation then make sure you ask beforehand. The critical element is how much time you have. It seems that panels are providing less and less time these days.\n\nThe usual formula is that you get an hour; half of which should be a presentation of your ideas followed by 30 minutes of questions. This isn\u2019t that much time, particularly for a big project that covers all aspect of web design and production. Don\u2019t be afraid to ask for more time, though it is very rare that you will be granted any.\n\nAsk if there any areas that a) they particularly want you to cover and b) if there are any areas of your proposal that were weak.\n\nAsk who will be attending. The main reason for this is to see if the decision maker(s) will be present but it\u2019s also good to know if you\u2019re presenting to 3 or 30 people.\n\nWho should be there\n\nGenerally speaking, I think two is the ideal number. Though I have done many presentations on my own, I always feel having two people to bounce ideas around with and have a bit of banter with, works well. You are not only trying to sell your ideas and expertise but also yourselves. One of the main things in the panels minds will be \u2013 \u201ccan I work with these people?\u201d\n\nHaving more than two people at a presentation often looks like you\u2019re wheeling people out just to demonstrate that they exist.\n\nWhat makes a client want to hire you?\n\nIn a nutshell: Confidence, Personality, Enthusiasm.\n\nYou can impart confidence by being well prepared and professional, providing examples and demonstrations and talking about your processes. You may find project management boring but pretty much every potential client will want to feel reassured that you manage your projects effectively.\n\nAs well as demonstrating that you know what you\u2019re talking about, it is important to encourage, and be part of, discussion about the project. Be prepared to suggest and challenge and be willing to say \u201cI don\u2019t know\u201d.\n\nAlso, no-one likes a show-off so don\u2019t over promote yourself; encourage them to contact your existing clients.\n\nWhat makes a client like you?\n\nEngaging with a potential client is tricky and it\u2019s probably the area where you need to be most on your toes and try to gauge the reaction of the client. We recommend the following:\n\n\n\tEncourage questions throughout\n\tAsk if you make sense \u2013 which encourages questions if you\u2019re not getting any\n\tHumour \u2013 though don\u2019t keep trying to be funny if you\u2019re not getting any laughs!\n\tBe willing to go off track\n\tRead your audience\n\tEmpathise with the process \u2013 chances are, most of the people in front of you would rather be doing something else\n\tThink about what you wear \u2013 this sounds daft but do you want to be seen as either the \u2018stiff in the suit\u2019 or the \u2018scruffy art student\u2019? Chances are neither character would get hired.\n\n\nDifferentiation\n\nSometimes, especially if you think you are an outsider, it\u2019s worth taking a few risks. I remember my colleague Paul starting off a presentation once with the line (backed up on screen) \u2013 \u201cHeadscape is not a usability consultancy\u201d. This was in response to the clients request to engage a usability consultancy. The thrust of Paul\u2019s argument was that we are a lot more than that.\n\nThis really worked. We were the outside choice but they ended up hiring us. Basically, this differentiated us from the crowd. It showed that we are prepared to take risks and think, dare I say it, outside of the box.\n\nDealing with difficult characters \n\nHow you react to tricky questioning is likely to be what determines whether you have a good or bad presentation. Here are a few of those characters that so often turn up in panels:\n\nThe techie \u2013 this is likely to be the situation where you need to say \u201cI don\u2019t know\u201d. Don\u2019t bluff as you are likely to dig yourself a great big embarrassment-filled hole. Promise to follow up with more information and make sure that you do so as quickly as possible after the pitch. \n\nThe \u2018hard man\u2019 MD \u2013 this the guy who thinks it is his duty to throw \u2018curve ball\u2019 questions to see how you react. Focus on your track record (big name clients will impress this guy) and emphasise your processes.\n\nThe \u2018no clue\u2019 client \u2013 you need to take control and be the expert though you do need to explain the reasoning behind any suggestions you make. This person will be judging you on how much you are prepared to help them deliver the project.\n\nThe price negotiator \u2013 be prepared to discuss price but do not reduce your rate or the effort associated with your proposal. Fall back on modular pricing and try to reduce scope to come within budget. You may wish to offer a one-off discount to win a new piece of work but don\u2019t get into detail at the pitch.\n\nDon\u2019t panic\u2026\n\nIf you go into a presentation thinking \u2018we must win this\u2019 then, chances are, you won\u2019t. Relax and be yourself. If you\u2019re not hitting it off with the panel then so be it. You have to remember that quite often you will be making up the numbers in a tendering process. This is massively frustrating but, unfortunately, part of it. If it\u2019s not going well, concentrate on what you are offering and try to demonstrate your professionalism rather than your personality. Finally, be on your toes, watch people\u2019s reactions and pay attention to what they say and try to react accordingly.\n\nSo where are the secret techniques I hear you ask? Well, using the words \u2018secret\u2019 and \u2018technique\u2019 was probably a bit naughty. Most of this stuff is about being keen, using your brain and believing in yourself and what you are selling rather than following a strict set of rules.", "year": "2008", "author": "Marcus Lillington", "author_slug": "marcuslillington", "published": "2008-12-09T00:00:00+00:00", "url": "https://24ways.org/2008/charm-clients-win-pitches/", "topic": "business"}
{"rowid": 54, "title": "Putting My Patterns through Their Paces", "contents": "Over the last few years, the conversation around responsive design has shifted subtly, focusing not on designing pages, but on patterns: understanding the small, reusable elements that comprise a larger design system. And given that many of those patterns are themselves responsive, learning to manage these small layout systems has become a big part of my work.\nThe thing is, the more pattern-driven work I do, the more I realize my design process has changed in a number of subtle, important ways. I suppose you might even say that pattern-driven design has, in a few ways, redesigned me.\nMeet the Teaser\nHere\u2019s a recent example. A few months ago, some friends and I redesigned The Toast. (It was a really, really fun project, and we learned a lot.) Each page of the site is, as you might guess, stitched together from a host of tiny, reusable patterns. Some of them, like the search form and footer, are fairly unique, and used once per page; others are used more liberally, and built for reuse. The most prevalent example of these more generic patterns is the teaser, which is classed as, uh, .teaser. (Look, I never said I was especially clever.)\nIn its simplest form, a teaser contains a headline, which links to an article:\n\nFairly straightforward, sure. But it\u2019s just the foundation: from there, teasers can have a byline, a description, a thumbnail, and a comment count. In other words, we have a basic building block (.teaser) that contains a few discrete content types \u2013 some required, some not. In fact, very few of those pieces need to be present; to qualify as a teaser, all we really need is a link and a headline. But by adding more elements, we can build slight variations of our teaser, and make it much, much more versatile.\n\n        Nearly every element visible on this page is built out of our generic \u201cteaser\u201d pattern.\n    \nBut the teaser variation I\u2019d like to call out is the one that appears on The Toast\u2019s homepage, on search results or on section fronts. In the main content area, each teaser in the list features larger images, as well as an interesting visual treatment: the byline and comment count were the most prominent elements within each teaser, appearing above the headline.\n\n        The approved visual design of our teaser, as it appears on lists on the homepage and the section fronts.\n    \nAnd this is, as it happens, the teaser variation that gave me pause. Back in the old days \u2013 you know, like six months ago \u2013 I probably would\u2019ve marked this module up to match the design. In other words, I would\u2019ve looked at the module\u2019s visual hierarchy (metadata up top, headline and content below) and written the following HTML:\n<div class=\"teaser\">\n  <p class=\"article-byline\">By <a href=\"#\">Author Name</a></p>\n  <a class=\"comment-count\" href=\"#\">126 <i>comments</i></a>\n  <h1 class=\"article-title\"><a href=\"#\">Article Title</a></h1>\n  <p class=\"teaser-excerpt\">Lorem ipsum dolor sit amet, consectetur\u2026</p>\n</div>\nBut then I caught myself, and realized this wasn\u2019t the best approach.\nMoving Beyond Layout\nSince I\u2019ve started working responsively, there\u2019s a question I work into every step of my design process. Whether I\u2019m working in Sketch, CSSing a thing, or researching a project, I try to constantly ask myself:\n\nWhat if someone doesn\u2019t browse the web like I do?\n\n\u2026Okay, that doesn\u2019t seem especially fancy. (And maybe you came here for fancy.) But as straightforward as that question might seem, it\u2019s been invaluable to so many aspects of my practice. If I\u2019m working on a widescreen layout, that question helps me remember the constraints of the small screen; if I\u2019m working on an interface that has some enhancements for touch, it helps me consider other input modes as I work. It\u2019s also helpful as a reminder that many might not see the screen the same way I do, and that accessibility (in all its forms) should be a throughline for our work on the web.\nAnd that last point, thankfully, was what caught me here. While having the byline and comment count at the top was a lovely visual treatment, it made for a terrible content hierarchy. For example, it\u2019d be a little weird if the page was being read aloud in a speaking browser: the name of the author and the number of comments would be read aloud before the title of the article with which they\u2019re associated.\nThat\u2019s why I find it\u2019s helpful to begin designing a pattern\u2019s hierarchy before its layout: to move past the visual presentation in front of me, and focus on the underlying content I\u2019m trying to support. In other words, if someone\u2019s encountering my design without the CSS I\u2019ve written, what should their experience be?\nSo I took a step back, and came up with a different approach:\n<div class=\"teaser\">\n  <h1 class=\"article-title\"><a href=\"#\">Article Title</a></h1>\n  <h2 class=\"article-byline\">By <a href=\"#\">Author Name</a></h2>\n  <p class=\"teaser-excerpt\">\n    Lorem ipsum dolor sit amet, consectetur\u2026\n    <a class=\"comment-count\" href=\"#\">126 <i>comments</i></a>\n  </p>\n</div>\nMuch, much better. This felt like a better match for the content I was designing: the headline \u2013 easily most important element \u2013 was at the top, followed by the author\u2019s name and an excerpt. And while the comment count is visually the most prominent element in the teaser, I decided it was hierarchically the least critical: that\u2019s why it\u2019s at the very end of the excerpt, the last element within our teaser. And with some light styling, we\u2019ve got a respectable-looking hierarchy in place:\n\nYeah, you\u2019re right \u2013 it\u2019s not our final design. But from this basic-looking foundation, we can layer on a bit more complexity. First, we\u2019ll bolster the markup with an extra element around our title and byline:\n<div class=\"teaser\">\n  <div class=\"teaser-hed\">\n    <h1 class=\"article-title\"><a href=\"#\">Article Title</a></h1>\n    <h2 class=\"article-byline\">By <a href=\"#\">Author Name</a></h2>\n  </div>\n  \u2026\n</div>\nWith that in place, we can use flexbox to tweak our layout, like so:\n.teaser-hed {\n  display: flex;\n  flex-direction: column-reverse;\n}\nflex-direction: column-reverse acts a bit like a change in gravity within our teaser-hed element, vertically swapping its two children.\n\nGetting closer! But as great as flexbox is, it doesn\u2019t do anything for elements outside our container, like our little comment count, which is, as you\u2019ve probably noticed, still stranded at the very bottom of our teaser.\nFlexbox is, as you might already know, wonderful! And while it enjoys incredibly broad support, there are enough implementations of old versions of Flexbox (in addition to plenty of bugs) that I tend to use a feature test to check if the browser\u2019s using a sufficiently modern version of flexbox. Here\u2019s the one we used:\nvar doc = document.body || document.documentElement;\nvar style = doc.style;\n\nif ( style.webkitFlexWrap == '' ||\n    style.msFlexWrap == '' ||\n    style.flexWrap == '' ) {\n  doc.className += \" supports-flex\";\n}\nEagle-eyed readers will note we could have used @supports feature queries to ask browsers if they support certain CSS properties, removing the JavaScript dependency. But since we wanted to serve the layout to IE we opted to write a little question in JavaScript, asking the browser if it supports flex-wrap, a property used elsewhere in the design. If the browser passes the test, then a class of supports-flex gets applied to our html element. And with that class in place, we can safely quarantine our flexbox-enabled layout from less-capable browsers, and finish our teaser\u2019s design:\n.supports-flex .teaser-hed {\n  display: flex;\n  flex-direction: column-reverse;\n}\n.supports-flex .teaser .comment-count {\n  position: absolute;\n  right: 0;\n  top: 1.1em;\n}\nIf the supports-flex class is present, we can apply our flexbox layout to the title area, sure \u2013 but we can also safely use absolute positioning to pull our comment count out of its default position, and anchor it to the top right of our teaser. In other words, the browsers that don\u2019t meet our threshold for our advanced styles are left with an attractive design that matches our HTML\u2019s content hierarchy; but the ones that pass our test receive the finished, final design.\n\nAnd with that, our teaser\u2019s complete.\nDiving Into Device-Agnostic Design\nThis is, admittedly, a pretty modest application of flexbox. (For some truly next-level work, I\u2019d recommend Heydon Pickering\u2019s \u201cFlexbox Grid Finesse\u201d, or anything Zoe Mickley Gillenwater publishes.) And for such a simple module, you might feel like this is, well, quite a bit of work. And you\u2019d be right! In fact, it\u2019s not one layout, but two: a lightly styled content hierarchy served to everyone, with the finished design served conditionally to the browsers that can successfully implement it. But I\u2019ve found that thinking about my design as existing in broad experience tiers \u2013 in layers \u2013 is one of the best ways of designing for the modern web. And what\u2019s more, it works not just for simple modules like our teaser, but for more complex or interactive patterns as well.\nOpen video\n    \n        Even a simple search form can be conditionally enhanced, given a little layered thinking.\n    \nThis more layered approach to interface design isn\u2019t a new one, mind you: it\u2019s been championed by everyone from Filament Group to the BBC. And with all the challenges we keep uncovering, a more device-agnostic approach is one of the best ways I\u2019ve found to practice responsive design. As Trent Walton once wrote,\n\nLike cars designed to perform in extreme heat or on icy roads, websites should be built to face the reality of the web\u2019s inherent variability.\n\nWe have a weird job, working on the web. We\u2019re designing for the latest mobile devices, sure, but we\u2019re increasingly aware that our definition of \u201csmartphone\u201d is much too narrow. Browsers have started appearing on our wrists and in our cars\u2019 dashboards, but much of the world\u2019s mobile data flows over sub-3G networks. After all, the web\u2019s evolution has never been charted along a straight line: it\u2019s simultaneously getting slower and faster, with devices new and old coming online every day. With all the challenges in front of us, including many we don\u2019t yet know about, a more device-agnostic, more layered design process can better prepare our patterns \u2013 and ourselves \u2013 for the future.\n(It won\u2019t help you get enough to eat at holiday parties, though.)", "year": "2015", "author": "Ethan Marcotte", "author_slug": "ethanmarcotte", "published": "2015-12-10T00:00:00+00:00", "url": "https://24ways.org/2015/putting-my-patterns-through-their-paces/", "topic": "code"}
{"rowid": 296, "title": "Animation in Design Systems", "contents": "Our modern front-end workflow has matured over time to include design systems and component libraries that help us stay organized, improve workflows, and simplify maintenance. These systems, when executed well, ensure proper documentation of the code available and enable our systems to scale with reduced communication conflicts. \nBut while most of these systems take a critical stance on fonts, colors, and general building blocks, their treatment of animation remains disorganized and ad-hoc. Let\u2019s leverage existing structures and workflows to reduce friction when it comes to animation and create cohesive and performant user experiences. \nUnderstand the importance of animation\nPart of the reason we treat animation like a second-class citizen is that we don\u2019t really consider its power. When users are scanning a website (or any environment or photo), they are attempting to build a spatial map of their surroundings. During this process, nothing quite commands attention like something in motion. \nWe are biologically trained to notice motion: evolutionarily speaking, our survival depends on it. For this reason, animation when done well can guide your users. It can aid and reinforce these maps, and give us a sense that we understand the UX more deeply. We retrieve information and put it back where it came from instead of something popping in and out of place. \n\n\u201cWhere did that menu go? Oh it\u2019s in there.\u201d \n\nFor a deeper dive into how animation can connect disparate states, I wrote about the Importance of Context-Shifting in UX Patterns for CSS-Tricks.\nAn animation flow on mobile.\nAnimation also aids in perceived performance. Viget conducted a study where they measured user engagement with a standard loading GIF versus a custom animation. Customers were willing to wait almost twice as long for the custom loader, even though it wasn\u2019t anything very fancy or crazy. Just by showing their users that they cared about them, they stuck around, and the bounce rates dropped.\n\n14 second generic loading screen.22 second custom loading screen.\nThis also works for form submission. Giving your personal information over to an online process like a static form can be a bit harrowing. It becomes more harrowing without animation used as a signal that something is happening, and that some process is completing. That same animation can also entertain users and make them feel as though the wait isn\u2019t as long. \nEli Fitch gave a talk at CSS Dev Conf called: \u201cPerceived Performance: The Only Kind That Really Matters\u201d, which is one of my favorite talk titles of all time. In it, he discussed how we tend to measure things like timelines and network requests because they are more quantifiable\u2013and therefore easier to measure\u2013but that measuring how a user feels when visiting the site is more important and worth the time and attention. \nIn his talk, he states \u201cHumans over-estimate passive waits by 36%, per Richard Larson of MIT\u201d. This means that if you\u2019re not using animation to speed up how fast the wait time of a form submission loads, users are perceiving it to be much slower than the dev tools timeline is recording.\nReign it in\nUnlike fonts, colors, and so on, we tend to add animation in as a last step, which leads to disorganized implementations that lack overall cohesion. If you asked a designer or developer if they would create a mockup or build a UI without knowing the fonts they were working with, they would dislike the idea. Not knowing the building blocks they\u2019re working with means that the design can fall apart or the development can break with something so fundamental left out at the start. Good animation works the same way.\nThe first step in reigning in your use of animation is to perform an animation audit. Look at all the places you are using animation on your site, or the places you aren\u2019t using animation but probably should. (Hint: perceived performance of a loader on a form submission can dramatically change your bounce rates.) \nNot sure how to perform a good audit? Val Head has a great chapter on it in her book, Designing Interface Animations, which has of buckets of research and great ideas.\nEven some beautiful component libraries that have animation in the docs make this mistake. You don\u2019t need every kind of animation, just like you don\u2019t need every kind of font. This bloats our code. Ask yourself questions like: do you really need a flip 180 degree animation? I can\u2019t even conceive of a place on a typical UI where that would be useful, yet most component libraries that I\u2019ve seen have a mixin that does just this.\nWhich leads to\u2026\nHave an opinion\nMany people are confused about Material Design. They think that Material Design is Motion Design, mostly because they\u2019ve never seen anyone take a stance on animation before and document these opinions well. But every time you use Material Design as your motion design language, people look at your site and think GOOGLE. Now that\u2019s good branding.\nBy using Google\u2019s motion design language and not your own, you\u2019re losing out on a chance to be memorable on your own website.\nWhat does having an opinion on motion look like in practice? It could mean you\u2019ve decided that you never flip things. It could mean that your eases are always going to glide. In that instance, you would put your efforts towards finding an ease that looks \u201cgliding\u201d and pulling out any transform: scaleX(-1) animation you find on your site. Across teams, everyone knows not to spend time mocking up flipping animation (even if they\u2019re working on an entirely different codebase), and to instead work on something that feels like it glides. You save time and don\u2019t have to communicate again and again to make things feel cohesive.\nCreate good developer resources\nSometimes people don\u2019t incorporate animation into a design system because they aren\u2019t sure how, beyond the base hover states. All animation properties can be broken into interchangeable pieces. This allows developers and designers alike to mix and match and iterate quickly, while still staying in the correct language. Here are some recommendations (with code and a demo to follow):\nCreate timing units, similar to h1, h2, h3. In a system I worked on recently, I called these t1, t2, t3. T1 would be reserved for longer pieces, down to t5 which is a bit like h5 in that it\u2019s the default (usually around .25 seconds or thereabouts).\nKeep animation easings for entrance, exit, entrance emphasis and exit emphasis that people can commonly refer to. This, and the animation-fill-mode, are likely to be the only two properties that can be reused for the entrance and exit of the animation.\nUse the animation-name property to define the keyframes for the animation itself. I would recommend starting with 5 or 6 before making a slew of them, and see if you need more. Writing 30 different animations might seem like a nice resource, but just like your color palette having too many can unnecessarily bulk up your codebase, and keep it from feeling cohesive. Think critically about what you need here. \nSee the Pen Modularized Animation for Component Libraries by Sarah Drasner (@sdras) on CodePen.\n\nThe example above is pared-down, but you can see how in a robust system, having pieces that are interchangeable cached across the whole system would save time for iterations and prototyping, not to mention make it easy to make adjustments for different feeling movement on the same animation easily.\nOne low hanging fruit might be a loader that leads to a success dialog. On a big site, you might have that pattern many times, so writing up a component that does only that helps you move faster while also allowing you to really zoom in and focus on that pattern. You avoid throwing something together at the last minute, or using a GIF, which are really heavy and mushy on retina. You can make singular pieces that look really refined and are reusable. \nReact and Vue Implementations are great for reusable components, as you can create a building block with a common animation pattern, and once created, it can be a resource for all. Remember to take advantage of things like props to allow for timing and easing adjustments like we have in the previous example!\nResponsive\nAt the very least we should ensure that interaction also works well on mobile, but if we\u2019d like to create interactions that take advantage of all of the gestures mobile has to offer, we can use libraries like zingtouch or hammer to work with swipe or multiple finger detection. With a bit of work, these can all be created through native detection as well.\nResponsive web pages can specify initial-scale=1.0 in the meta tag so that the device is not waiting the required 300ms on the secondary tap before calling action. Interaction for touch events must either start from a larger touch-target (40px \u00d7 40px or greater) or use @media(pointer:coarse) as support allows.\nBuy-in\nSometimes people don\u2019t create animation resources simply because it gets deprioritized. But design systems were also something we once had to fight for, too. This year at CSS Dev Conf, Rachel Nabors demonstrated how to plot out animation wants vs. needs on a graph (reproduced with her permission) to help prioritize them:\n\n\nThis helps people you\u2019re working with figure out the relative necessity and workload of the addition of these animations and think more critically about it. You\u2019re also more likely to get something through if you\u2019re proving that what you\u2019re making is needed and can be reused. \nGood compromises can be made this way: \u201cwe\u2019re not going to go all out and create an animated \u2018About Us\u2019 page like you wanted, but I suppose we can let our users know their contact email went through with a small progress and success notification.\u201d \nSuccessfully pushing smaller projects through helps build trust with your team, and lets them see what this type of collaboration can look like. This builds up the type of relationship necessary to push through projects that are more involved. It can\u2019t be overstressed that good communication is key.\nGet started!\nWith these tools and good communication, we can make our codebases more efficient, performant, and feel better for our users. We can enhance the user experience on our sites, and create great resources for our teams to allow them to move more quickly while innovating beautifully.", "year": "2016", "author": "Sarah Drasner", "author_slug": "sarahdrasner", "published": "2016-12-16T00:00:00+00:00", "url": "https://24ways.org/2016/animation-in-design-systems/", "topic": "code"}
{"rowid": 210, "title": "Stop Leaving Animation to the Last Minute", "contents": "Our design process relies heavily on static mockups as deliverables and this makes it harder than it needs to be to incorporate UI animation in our designs. Talking through animation ideas and dancing out the details of those ideas can be fun; but it\u2019s not always enough to really evaluate or invest in animated design solutions. \nBy including deliverables that encourage discussing animation throughout your design process, you can set yourself (and your team) up for creating meaningful UI animations that feel just as much a part of the design as your colour palette and typeface. You can get out of that \u201crunning out of time to add in the animation\u201d trap by deliberately including animation in the early phases of your design process. This will give you both the space to treat animation as a design tool, and the room to iterate on UI animation ideas to come up with higher quality solutions. Two deliverables that can be especially useful for this are motion comps and animated interactive prototypes. \nMotion comps - an animation deliverable\nMotion comps (also called animatics or motion mock-ups) are usually video representation of UI animations. They are used to explore the details of how a particular animation might play out. And they\u2019re most often made with timeline-based tools like Adobe After Effects, Adobe Animate, or Tumult Hype. \nThe most useful things about motion comps is how they allow designers and developers to share the work of creating animations. (Instead of pushing all the responsibility of animation on one group or the other.) For example, imagine you\u2019re working on a design that has a content panel that can either be open or closed. You might create a mockup like the one below including the two different views: the closed state and the open state. If you\u2019re working with only static deliverables, these two artboards might be exactly what you handoff to developers along with the instruction to animate between the two. \n\nOn the surface that seems pretty straight forward, but even with this relatively simple transition there\u2019s a lot that those two artboards don\u2019t address. There are seven things that change between the closed state and the open state. That\u2019s seven things the developer building this out has to figure out how to move in and out of view, when, and in what order. And all of that is even before starting to write the code to make it work. \nBy providing only static comps, all the logic of the animation falls on the developer. This might go ok if she has the bandwidth and animation knowledge, but that\u2019s making an awful lot of assumptions.\nInstead, if you included a motion mock up like this with your static mock ups, you could share the work of figuring out the logic of the animation between design and development. Designers could work out the logic of the animation in the motion comp, exploring which items move at which times and in which order to create the opening and closing transitions. \n\nThe motion comp can also be used to iterate on different possible animation approaches before any production code has to be committed too. Sharing the work and giving yourself time to explore animation ideas before you\u2019re backed up again the deadline will lead to happier teammates and better design solutions. \nWhen to use motion comps\nI\u2019m not a fan of making more deliverables just for the sake of having more things to make, so I find it helps to narrow down what question I\u2019m trying answer before choosing which sort of deliverable to make to investigate. \nMotion comps can be most helpful for answering questions like: \n\nExactly how should this animation look? \nWhich items should move? Where? And when? \nDo the animation qualities reflect our brand or our voice and tone?\nOne of the added bonuses of creating motion comps to answer these questions is that you\u2019ll have a concrete thing to bring to design critiques or reviews to get others\u2019 input on them as well.\n\nUsing motion comps as handoff\nMotion comps are often used to handoff animation ideas from design to development. They can be super useful for this, but they\u2019re even more useful when you include the details of the motion specs with them. (It\u2019s difficult, if not impossible, to glean these details from playing back a video.)\nMore specifically, you\u2019ll want to include:\n\nDurations and the properties animated for each animation\nEasing curve values or spring values used\nDelay values and repeat counts\n\nIn many cases you\u2019ll have to collect these details up manually. But this isn\u2019t necessarily something that that will take a lot of time. If you take note of them as you\u2019re creating the motion comp, chances are most of these details will already be top of  mind. (Also, if you use After Effects for your motion comps, the Inspector Spacetime plugin might be helpful for this task.)\nAnimated prototypes - an interactive deliverable\nMaking prototypes isn\u2019t a new idea for web work by any stretch, but creating prototypes that include animation \u2013 or even creating prototypes specifically to investigate potential animation solutions \u2013 can go a long way towards having higher quality animations in your final product.\nInteractive prototypes are web or app-based, or displayed in a particular tool\u2019s preview window to create a useable version of interactions that might end up in the end product. They\u2019re often made with prototyping apps like Principle, Framer, or coded up in HTML, CSS and JS directly like the example below.\nSee the Pen Prototype example by Val Head (@valhead) on CodePen.\n\nThe biggest different between motion comps and animated prototypes is the interactivity. Prototypes can reposed to taps, drags or gestures, while motion comps can only play back in a linear fashion. Generally speaking, this makes prototypes a bit more of an effort to create, but they can also help you solve different problems. The interactive nature of prototypes can also make them useful for user testing to further evaluate potential solutions. \nWhen to use prototypes\nWhen it comes to testing out animation ideas, animated prototypes can be especially helpful in answering questions like these: \n\nHow will this interaction feel to use? (Interactive animations often have different timing needs than animations that are passively viewed.)\nWhat will the animation be like with real data or real content? \nDoes this animation fit the context of the task at hand? \n\nPrototypes can be used to investigate the same questions that motion comps do if you\u2019re comfortable working in code or your prototyping tool of choice has capabilities to address high fidelity animation details. There are so many different prototyping tools out there at the moment, you\u2019re sure to be able to find one that fits your needs. \nAs a quick side note: If you\u2019re worried that your coding skills might not be up to par to prototype in code, know that prototype code doesn\u2019t have to be production quality code. Animated prototypes\u2019 main concern is working out the animation details. Once you\u2019ve arrived at a combination of animations that works, the animation specifics can be extracted or the prototype can be refactored for production.\nMotion comp or prototype?\nBoth motion comps and prototypes can be extremely useful in the design process and you can use whichever one (or ones) that best fits your team\u2019s style. The key thing that both offer is a way to make animation ideas visible and sharable. When you and your teammate are both looking at the same deliverable, you can be confident you\u2019re talking about the same thing and discuss its pros and cons more easily than just describing the idea verbally. \nMotion comps tend to be more useful earlier in the design process when you want to focus on the motion without worrying about the underlying structure or code yet. Motion comps also be great when you want to try something completely new. Some folks prefer motion comps because the tools for making them feel more familiar to them which means they can work faster. \nPrototypes are most useful for animations that rely heavily on interaction. (Getting the timing right for interactions can be tough without the interaction part sometimes.) Prototypes can also be helpful to investigate and optimize performance if that\u2019s a specific concern.\nGive them a try\nWhichever deliverables you choose to highlight your animation decisions, including them in your design reviews, critiques, or other design discussions will help you make better UI animation choices. More discussion around UI animation ideas during the design phase means greater buy-in, more room for iteration, and higher quality UI animations in your designs.

{"rowid": 21, "title": "Keeping Parts of Your Codebase Private on GitHub", "contents": "Open source is brilliant, there\u2019s no denying that, and GitHub has been  instrumental in open source\u2019s recent success. I\u2019m a keen open-sourcerer myself, and I have a number of projects on GitHub. However, as great as sharing code is, we often want to keep some projects to ourselves. To this end, GitHub created private repositories which act like any other Git repository, only, well, private!\n\nA slightly less common issue, and one I\u2019ve come up against myself, is the desire to only keep certain parts of a codebase private. A great example would be my site, CSS Wizardry; I want the code to be open source so that people can poke through and learn from it, but I want to keep any draft blog posts private until they are ready to go live. Thankfully, there is a very simple solution to this particular problem: using multiple remotes.\n\nBefore we begin, it\u2019s worth noting that you can actually build  a GitHub Pages site from a private repo. You can keep the entire source private, but still have GitHub build and display a full Pages/Jekyll site. I do this with csswizardry.net. This post will deal with the more specific problem of keeping only certain parts of the codebase (branches) private, and expose parts of it as either an open source project, or a built GitHub Pages site.\n\nN.B. This post requires some basic Git knowledge.\n\nAdding your public remote\n\nLet\u2019s assume you\u2019re starting from scratch and you currently have no repos set up for your project. (If you do already have your public repo set up, skip to the \u201cAdding your private remote\u201d section.)\n\nSo, we have a clean slate: nothing has been set up yet, we\u2019re doing all of that now. On GitHub, create two repositories. For the sake of this article we shall call them site.com and private.site.com. Make the site.com repo public, and the private.site.com repo private (you will need a paid GitHub account).\n\nOn your machine, create the site.com directory, in which your project will live. Do your initial work in there, commit some stuff \u2014 whatever you need to do. Now we need to link this local Git repo on your machine with the public repo (remote) on GitHub. We should all be used to this:\n\n$ git remote add origin git@github.com:[user]/site.com.git\n\nHere we are simply telling Git to add a remote called origin which lives at git@github.com:[user]/site.com.git. Simple stuff. Now we need to push our current branch (which will be master, unless you\u2019ve explicitly changed it) to that remote:\n\n$ git push -u origin master\n\nHere we are telling Git to push our master branch to a corresponding master branch on the remote called origin, which we just added. The -u sets upstream tracking, which basically tells Git to always shuttle code on this branch between the local master branch and the master branch on the origin remote. Without upstream tracking, you would have to tell Git where to push code to (and pull it from) every time you ran the push or pull commands. This sets up a permanent bond, if you like.\n\nThis is really simple stuff, stuff that you will probably have done a hundred times before as a Git user. Now to set up our private remote.\n\nAdding your private remote\n\nWe\u2019ve set up our public, open source repository on GitHub, and linked that to the repository on our machine. All of this code will be publicly viewable on GitHub.com. (Remember, GitHub is just a host of regular Git repositories, which also puts a nice GUI around it all.) We want to add the ability to keep certain parts of the codebase private. What we do now is add another remote repository to the same local repository. We have two repos on GitHub (site.com and private.site.com), but only one repository (and, therefore, one directory) on our machine. Two GitHub repos, and one local one.\n\nIn your local repo, check out a new branch. For the sake of this article we shall call the branch dev. This branch might contain work in progress, or draft blog posts, or anything you don\u2019t want to be made publicly viewable on GitHub.com. The contents of this branch will, in a moment, live in our private repository.\n\n$ git checkout -b dev\n\nWe have now made a new branch called dev off the branch we were on last (master, unless you renamed it).\n\nNow we need to add our private remote (private.site.com) so that, in a second, we can send this branch to that remote:\n\n$ git remote add private git@github.com:[user]/private.site.com.git\n\nLike before, we are just telling Git to add a new remote to this repo, only this time we\u2019ve called it private and it lives at git@github.com:[user]/private.site.com.git. We now have one local repo on our machine which has two remote repositories associated with it.\n\nNow we need to tell our dev branch to push to our private remote:\n\n$ git push -u private dev\n\nHere, as before, we are pushing some code to a repo. We are saying that we want to push the dev branch to the private remote, and, once again, we\u2019ve set up upstream tracking. This means that, by default, the dev branch will only push and pull to and from the private remote (unless you ever explicitly state otherwise).\n\nNow you have two branches (master and dev respectively) that push to two remotes (origin and private respectively) which are public and private respectively.\n\nAny work we do on the master branch will push and pull to and from our publicly viewable remote, and any code on the dev branch will push and pull from our private, hidden remote.\n\nAdding more branches\n\nSo far we\u2019ve only looked at two branches pushing to two remotes, but this workflow can grow as much or as little as you\u2019d like. Of course, you\u2019d never do all your work in only two branches, so you might want to push any number of them to either your public or private remotes. Let\u2019s imagine we want to create a branch to try something out real quickly:\n\n$ git checkout -b test\n\nNow, when we come to push this branch, we can choose which remote we send it to:\n\n$ git push -u private test\n\nThis pushes the new test branch to our private remote (again, setting the persistent tracking with -u).\n\nYou can have as many or as few remotes or branches as you like.\n\nCombining the two\n\nLet\u2019s say you\u2019ve been working on a new feature in private for a few days, and you\u2019ve kept that on the private remote. You\u2019ve now finalised the addition and want to move it into your public repo. This is just a simple merge. Check out your master branch:\n\n$ git checkout master\n\nThen merge in the branch that contained the feature:\n\n$ git merge dev\n\nNow master contains the commits that were made on dev and, once you\u2019ve pushed master to its remote, those commits will be viewable publicly on GitHub:\n\n$ git push\n\nNote that we can just run $ git push on the master branch as we\u2019d previously set up our upstream tracking (-u).\n\nMultiple machines\n\nSo far this has covered working on just one machine; we had two GitHub remotes and one local repository. Let\u2019s say you\u2019ve got yourself a new Mac (yay!) and you want to clone an existing project:\n\n$ git clone git@github.com:[user]/site.com.git\n\nThis will not clone any information about the remotes you had set up on the previous machine. Here you have a fresh clone of the public project and you will need to add the private remote to it again, as above.\n\nDone!\n\nIf you\u2019d like to see me blitz through all that in one go, check the showterm recording.\n\nThe beauty of this is that we can still share our code, but we don\u2019t have to develop quite so openly all of the time. Building a framework with a killer new feature? Keep it in a private branch until it\u2019s ready for merge. Have a blog post in a Jekyll site that you\u2019re not ready to make live? Keep it in a private drafts branch. Working on a new feature for your personal site? Tuck it away until it\u2019s finished. Need a staging area for a Pages-powered site? Make a staging remote with its own custom domain.\n\nAll this boils down to, really, is the fact that you can bring multiple remotes together into one local codebase on your machine. What you do with them is entirely up to you!", "year": "2013", "author": "Harry Roberts", "author_slug": "harryroberts", "published": "2013-12-09T00:00:00+00:00", "url": "https://24ways.org/2013/keeping-parts-of-your-codebase-private-on-github/", "topic": "code"}
{"rowid": 163, "title": "Get To Grips with Slippy Maps", "contents": "Online mapping has definitely hit mainstream. Google Maps made \u2018slippy maps\u2019 popular and made it easy for any developer to quickly add a dynamic map to his or her website. You can now find maps for store locations, friends nearby, upcoming events, and embedded in blogs. \n\nIn this tutorial we\u2019ll show you how to easily add a map to your site using the Mapstraction mapping library. There are many map providers available to choose from, each with slightly different functionality, design, and terms of service. Mapstraction makes deciding which provider to use easy by allowing you to write your mapping code once, and then easily switch providers.\n\nAssemble the pieces\n\nUtilizing any of the mapping library typically consists of similar overall steps:\n\n\n\tCreate an HTML div to hold the map\n\tInclude the Javascript libraries\n\tCreate the Javascript Map element\n\tSet the initial map center and zoom level\n\tAdd markers, lines, overlays and more\n\n\nCreate the Map Div\n\nThe HTML div is where the map will actually show up on your page. It needs to have a unique id, because we\u2019ll refer to that later to actually put the map here. This also lets you have multiple maps on a page, by creating individual divs and Javascript map elements. The size of the div also sets the height and width of the map. You set the size using CSS, either inline with the element, or via a CSS reference to the element id or class. For this example, we\u2019ll use inline styling.\n\n<div id=\"map\" style=\"width: 400px; height: 400px;\"></div>\n\nInclude Javascript libraries\n\nA mapping library is like any Javascript library. You need to include the library in your page before you use the methods of that library. For our tutorial, we\u2019ll need to include at least two libraries: Mapstraction, and the mapping API(s) we want to display. Our first example we\u2019ll use the ubiquitous Google Maps library. However, you can just as easily include Yahoo, MapQuest, or any of the other supported libraries.\n\nAnother important aspect of the mapping libraries is that many of them require an API key. You will need to agree to the terms of service, and get an API key these.\n\n<script src=\"http://maps.google.com/maps?file=api&v=2&key=YOUR_KEY\" type=\"text/javascript\"></script>\n<script type=\"text/javascript\" src=\"http://mapstraction.com/src/mapstraction.js\"></script>\n\nCreate the Map\n\nGreat, we\u2019ve now put in all the pieces we need to start actually creating our map. This is as simple as creating a new Mapstraction object with the id of the HTML div we created earlier, and the name of the mapping provider we want to use for this map. \n\nWith several of the mapping libraries you will need to set the map center and zoom level before the map will appear. The map centering actually triggers the initialization of the map. \n\nvar mapstraction = new Mapstraction('map','google');\nvar myPoint = new LatLonPoint(37.404,-122.008);\nmapstraction.setCenterAndZoom(myPoint, 10);\n\nA note about zoom levels. The setCenterAndZoom function takes two parameters, the center as a LatLonPoint, and a zoom level that has been defined by mapping libraries. The current usage is for zoom level 1 to be \u201czoomed out\u201d, or view the entire earth \u2013 and increasing the zoom level as you zoom in. Typically 17 is the maximum zoom, which is about the size of a house. \n\nDifferent mapping providers have different quality of zoomed in maps over different parts of the world. This is a perfect reason why using a library like Mapstraction is very useful, because you can quickly change mapping providers to accommodate users in areas that have bad coverage with some maps. \n\nTo switch providers, you just need to include the Javascript library, and then change the second parameter in the Mapstraction creation. Or, you can call the switch method to dynamically switch the provider.\n\nSo for Yahoo Maps  (demo):\n\nvar mapstraction = new Mapstraction('map','yahoo');\n\nor Microsoft Maps (demo):\n\nvar mapstraction = new Mapstraction('map','microsoft');\n\nwant a 3D globe in your browser? try FreeEarth (demo):\n\nvar mapstraction = new Mapstraction('map','freeearth');\n\nor even OpenStreetMap (free your data!)  (demo):\n\nvar mapstraction = new Mapstraction('map','openstreetmap');\n\nVisit the Mapstraction multiple map demo page for an example of how easy it is to have many maps on your page, each with a different provider. \n\nAdding Markers\n\nWhile adding your first map is fun, and you can probably spend hours just sliding around, the point of adding a map to your site is usually to show the location of something. So now you want to add some markers. There are a couple of ways to add to your map.\n\nThe simplest is directly creating markers. You could either hard code this into a rather static page, or dynamically generate these using whatever tools your site is built on.\n\nvar marker = new Marker( new LatLonPoint(37.404,-122.008) );\nmarker.setInfoBubble(\"It's easy to add maps to your site\");\nmapstraction.addMarker( marker );\n\nThere is a lot more you can do with markers, including changing the icon, adding timestamps, automatically opening the bubble, or making them draggable. \n\nWhile it is straight-forward to create markers one by one, there is a much easier way to create a large set of markers. And chances are, you can make it very easy by extending some data you already are sharing: RSS. \n\nSpecifically, using GeoRSS you can easily add a large set of markers directly to a map. GeoRSS is a community built standard (like Microformats) that added geographic markup to RSS and Atom entries. It\u2019s as simple as adding <georss:point>42 -83</georss:point> to your feeds to share items via GeoRSS. Once you\u2019ve done that, you can add that feed as an \u2018overlay\u2019 to your map using the function:\n\nmapstraction.addOverlay(\"http://api.flickr.com/services/feeds/groups_pool.gne?id=322338@N20&format=rss_200&georss=1\");\n\nMapstraction also supports KML for many of the mapping providers. So it\u2019s easy to add various data sources together with your own data. Check out Mapufacture for a growing index of available GeoRSS feeds and KML documents. \n\nPlay with your new toys\n\nMapstraction offers a lot more functionality you can utilize for demonstrating a lot of geographic data on your website. It also includes geocoding and routing abstraction layers for making sure your users know where to go.

{"rowid": 174, "title": "Type-Inspired Interfaces", "contents": "One of the things that terrifies me most about a new project is the starting point. How is the content laid out? What colors do I pick? Once things like that are decided, it becomes significantly easier to continue design, but it\u2019s the blank page where I spend the most time.\n\nTo that end, I often start by choosing type. I don\u2019t need to worry about colors or layout or anything else\u2026 just the right typefaces that support the art direction. (This article won\u2019t focus on how to choose a typeface, but there are some really great resources if you interested in that sort of thing.)\n\nAnd just like that, all your work is done. \u201cHold it just a second,\u201d you might say. \u201cAll I\u2019ve done is pick type. I still have to do the rest!\u201d\n\nTo which I would reply, \u201cSilly rabbit. You already have!\u201d You see, picking the right typeface gets you farther than you might think. Here are a few tips on taking cues from type to design interfaces and interface elements.\n\nPerfecting Web 2.0\n\nIf you\u2019re going for that beloved rounded corner look, you might class it up a bit by choosing the wonderful Omnes Pro by Joshua Darden. As the typeface already has a rounded aesthetic, making buttons that fit the style should be pretty easy.\n\nI\u2019ve found that using multiples helps to keep your interfaces looking balanced and proportional. Noticing that the top left edge of the letter \u201cP\u201d has about an 12px corner radius, let\u2019s choose a 24px radius for our button (a multiple of 2), so that we get proper rounded corners. By taking mathematical measurements from the typeface, our button looks more thought out than just \u201cplace arbitrary text on arbitrarily-sized button.\u201d Pretty easy, eh?\n\n\n\nWhat\u2019s in a name(plate)?\n\nRounded buttons are pretty popular buttons nowadays, so let\u2019s try something a bit more stylized.\n\nHave a gander at Brothers, a sturdy face from Emigre. The chiseled edges give us a perfect cue for a stylized button. Using the same slope, you can make plated-looking buttons that fit a different kind of style.\n\n\n\nHeadlining\n\nYou might even take some cues from the style of the typeface itself. Didone serifs are known for their lack of brackets\u30fcthat is, a gradual transition from the stem to the serif. Instead, they typically connect at a right angle. Another common characteristic is the high contrast in the strokes: very thick stems, very thin serifs.\n\nSo, when using a high contrast typeface, you can use it to your advantage to enhance hierarchy. Following our \u201cmultiples\u201d guideline, a 12px measurement from the stems helps us create a top rule with a height of 24px (a multiple of 2). We can take the exact 1px measurement from the serif\u2014a multiple of 1\u2014to create the bottom rule. Voil\u00e0! I use this technique a lot.\n\n\n\nSwashbucklers\n\nAnd don\u2019t forget the importance of visual \u201cspeed bumps\u201d to break up long passages of text. A beautiful face like Alejandro Paul\u2019s Ministry Script has over a thousand characters that can be manipulated or even combined to create elegant interface elements. Altering the partial differential character (\u2202) creates a delightful ornament that can help to guide the eye through content.\n\n\n\nStagger & Swagger\n\nWhat about layout? How can we use typography to inform how our content is displayed?\n\nLet\u2019s take a typeface like Assembler. We might use this for a design that needs to feel uneasy or uncomfortable. In design terms, that might translate into using irregular shapes and asymmetry. Using the proportional distances and degrees from the perpendiculars, we could easily create a multi-column layout that jives with the general tone. And for all you skeptics that don\u2019t think a layout like this is doable on the web, stranger things have happened.\n\n Background texture generously offered by Bittbox.\n\nOverall Design Direction\n\nFinally, your typography could impact the entire look of the site, from the navigation to the interaction and everything in between. Check out how the (now-defunct) Nike Free site\u2019s typography echoes the product itself, and in turn influences the navigation.\n\n\n\nFind Your Type\n\nWith thousands of fonts to choose from, the possibilities are ridiculously open. From angles to radii to color to weight, you\u2019ve got endless fodder before you. Great type designers spent countless hours slaving over these detailed letterforms; take advantage of it! Don\u2019t feel like you have to limit yourself to the same old Helvetica and wet floors\u2026 unless your design calls for it. \n\nHappy hunting!", "year": "2009", "author": "Dan Mall", "author_slug": "danmall", "published": "2009-12-07T00:00:00+00:00", "url": "https://24ways.org/2009/type-inspired-interfaces/", "topic": "design"}
{"rowid": 104, "title": "Sitewide Search On A Shoe String", "contents": "One of the questions I got a lot when I was building web sites for smaller businesses was if I could create a search engine for their site. Visitors should be able to search only this site and find things without the maintainer having to put \u201crelated articles\u201d  or \u201cfeatured content\u201d links on every page by hand. \n\nBack when this was all fields this wasn\u2019t easy as you either had to write your own scraping tool, use ht://dig or a paid service from providers like Yahoo, Altavista or later on Google. In the former case you had to swallow the bitter pill of computing and indexing all your content and storing it in a database for quick access and in the latter it hurt your wallet.\n\nTimes have moved on and nowadays you can have the same functionality for free using Yahoo\u2019s \u201cBuild your own search service\u201d \u2013 BOSS. The cool thing about BOSS is that it allows for a massive amount of hits a day and you can mash up the returned data in any format you want. Another good feature of it is that it comes with JSON-P as an output format which makes it possible to use it without any server-side component!\n\nStarting with a working HTML form\n\nIn order to add a search to your site, you start with a simple HTML form which you can use without JavaScript. Most search engines will allow you to filter results by domain. In this case we will search \u201cbbc.co.uk\u201d. If you use Yahoo as your standard search, this could be: \n\n<form id=\"customsearch\" action=\"http://search.yahoo.com/search\">\n\t<div>\n\t\t<label for=\"p\">Search this site:</label>\n\t\t<input type=\"text\" name=\"p\" id=\"term\">\n\t\t<input type=\"hidden\" name=\"vs\" id=\"site\" value=\"bbc.co.uk\">\n\t\t<input type=\"submit\" value=\"go\">\n\t</div>\n</form>\n\nThe Google equivalent is:\n\n<form id=\"customsearch\" action=\"http://www.google.co.uk/search\">\n\t<div>\n\t\t<label for=\"p\">Search this site:</label>\n\t\t<input type=\"text\" name=\"as_q\" id=\"term\">\n\t\t<input type=\"hidden\" name=\"as_sitesearch\" id=\"site\" value=\"bbc.co.uk\">\n\t\t<input type=\"submit\" value=\"go\">\n\t</div>\n</form>\n\nIn any case make sure to use the ID term for the search term and site for the site, as this is what we are going to use for the script. To make things easier, also have an ID called customsearch on the form.\n\nTo use BOSS, you should get your own developer API for BOSS and replace the one in the demo code. There is click tracking on the search results to see how successful your app is, so you should make it your own.\n\nAdding the BOSS magic\n\nBOSS is a REST API, meaning you can use it in any HTTP request or in a browser by simply adding the right parameters to a URL. Say for example you want to search \u201cbbc.co.uk\u201d for \u201cchristmas\u201d all you need to do is open the following URL:\n\nhttp://boss.yahooapis.com/ysearch/web/v1/christmas?sites=bbc.co.uk&format=xml&appid=YOUR-APPLICATION-ID\n\nTry it out and click it to see the results in XML. We don\u2019t want XML though, which is why we get rid of the format=xml parameter which gives us the same information in JSON:\n\nhttp://boss.yahooapis.com/ysearch/web/v1/christmas?sites=bbc.co.uk&appid=YOUR-APPLICATION-ID\n\nJSON makes most sense when you can send the output to a function and immediately use it. For this to happen all you need is to add a callback parameter and the JSON will be wrapped in a function call. Say for example we want to call SITESEARCH.found() when the data was retrieved we can do it this way:\n\nhttp://boss.yahooapis.com/ysearch/web/v1/christmas?sites=bbc.co.uk&callback=SITESEARCH.found&appid=YOUR-APPLICATION-ID\n\nYou can use this immediately in a script node if you want to. The following code would display the total amount of search results for the term christmas on bbc.co.uk as an alert:\n\n<script type=\"text/javascript\">\n\tvar SITESEARCH = {};\n\tSITESEARCH.found = function(o){\n\t\talert(o.ysearchresponse.totalhits);\n\t}\n</script>\n<script type=\"text/javascript\" src=\"http://boss.yahooapis.com/ysearch/web/v1/christmas?sites=bbc.co.uk&callback=SITESEARCH.found&appid=Kzv_lcHV34HIybw0GjVkQNnw4AEXeyJ9Rb1gCZSGxSRNrcif_HdMT9qTE1y9LdI-\">\n</script>\n\nHowever, for our example, we need to be a bit more clever with this.\n\nEnhancing the search form\n\n\n\n\nHere\u2019s the script that enhances a search form to show results below it.\n\nSITESEARCH = function(){\n\tvar config = {\n\t\tIDs:{\n\t\t\tsearchForm:'customsearch',\n\t\t\tterm:'term',\n\t\t\tsite:'site'\n\t\t},\n\t\tloading:'Loading results...',\n\t\tnoresults:'No results found.',\n\t\tappID:'YOUR-APP-ID',\n\t\tresults:20\n\t};\n\tvar form;\n\tvar out;\n\tfunction init(){\n\t\tif(config.appID === 'YOUR-APP-ID'){\n\t\t\talert('Please get a real application ID!');\n\t\t} else {\n\t\t\tform = document.getElementById(config.IDs.searchForm);\n\t\t\tif(form){\n\t\t\t\tform.onsubmit = function(){\n\t\t\t\t\tvar site = document.getElementById(config.IDs.site).value;\n\t\t\t\t\tvar term = document.getElementById(config.IDs.term).value;\n\t\t\t\t\tif(typeof site === 'string' && typeof term === 'string'){\n\t\t\t\t\t\tif(typeof out !== 'undefined'){\n\t\t\t\t\t\t\tout.parentNode.removeChild(out);\n\t\t\t\t\t\t}\n\t\t\t\t\t\tout = document.createElement('p');\n\t\t\t\t\t\tout.appendChild(document.createTextNode(config.loading));\n\t\t\t\t\t\tform.appendChild(out);\n\t\t\t\t\t\tvar APIurl = 'http://boss.yahooapis.com/ysearch/web/v1/' + \n\t\t\t\t\t\t\t\t\t\t\t\t\tterm + '?callback=SITESEARCH.found&sites=' + \n\t\t\t\t\t\t\t\t\t\t\t\t\tsite + '&count=' + config.results + \n\t\t\t\t\t\t\t\t\t\t\t\t\t'&appid=' + config.appID;\n\t\t\t\t\t\tvar s = document.createElement('script');\n\t\t\t\t\t\ts.setAttribute('src',APIurl);\n\t\t\t\t\t\ts.setAttribute('type','text/javascript');\n\t\t\t\t\t\tdocument.getElementsByTagName('head')[0].appendChild(s);\n\t\t\t\t\t\treturn false;\n\t\t\t\t\t}\n\t\t\t\t};\n\t\t\t}\n\t\t}\n\t};\n\tfunction found(o){\n\t\tvar list = document.createElement('ul');\n\t\tvar results = o.ysearchresponse.resultset_web;\n\t\tif(results){\n\t\t\tvar item,link,description;\n\t\t\tfor(var i=0,j=results.length;i<j;i++){\n\t\t\t\titem = document.createElement('li');\n\t\t\t\tlink = document.createElement('a');\n\t\t\t\tlink.setAttribute('href',results[i].clickurl);\n\t\t\t\tlink.innerHTML = results[i].title;\n\t\t\t\titem.appendChild(link);\n\t\t\t\tdescription = document.createElement('p');\n\t\t\t\tdescription.innerHTML = results[i]['abstract'];\n\t\t\t\titem.appendChild(description);\n\t\t\t\tlist.appendChild(item);\n\t\t\t}\n\t\t} else {\n\t\t\tlist = document.createElement('p');\n\t\t\tlist.appendChild(document.createTextNode(config.noresults));\n\t\t}\n\t\tform.replaceChild(list,out);\n\t\tout = list;\n\t};\n\treturn{\n\t\tconfig:config,\n\t\tinit:init,\n\t\tfound:found\n\t};\n}();\n\nOooohhhh scary code! Let\u2019s go through this one bit at a time:\n\nWe start by creating a module called SITESEARCH and give it an configuration object: \n\nSITESEARCH = function(){\n\tvar config = {\n\t\tIDs:{\n\t\t\tsearchForm:'customsearch',\n\t\t\tterm:'term',\n\t\t\tsite:'site'\n\t\t},\n\t\tloading:'Loading results...',\n\t\tappID:'YOUR-APP-ID',\n\t\tresults:20\n\t}\n\nConfiguration objects are a great idea to make your code easy to change and also to override. In this case you can define different IDs than the one agreed upon earlier, define a message to show when the results are loading, when there aren\u2019t any results, the application ID and the number of results that should be displayed.\n\nNote: you need to replace \u201cYOUR-APP-ID\u201d with the real ID you retrieved from BOSS, otherwise the script will complain! \n\nvar form;\nvar out;\nfunction init(){\n\tif(config.appID === 'YOUR-APP-ID'){\n\t\talert('Please get a real application ID!');\n\t} else {\n\nWe define form and out as variables to make sure that all the methods in the module have access to them. We then check if there was a real application ID defined. If there wasn\u2019t, the script complains and that\u2019s that.      \n\nform = document.getElementById(config.IDs.searchForm);\nif(form){\n\tform.onsubmit = function(){\n\t\tvar site = document.getElementById(config.IDs.site).value;\n\t\tvar term = document.getElementById(config.IDs.term).value;\n\t\tif(typeof site === 'string' && typeof term === 'string'){      \n\nIf the application ID was a winner, we check if the form with the provided ID exists and apply an onsubmit event handler. The first thing we get is the values of the site we want to search in and the term that was entered and check that those are strings.\n\nif(typeof out !== 'undefined'){\n\tout.parentNode.removeChild(out);\n}\nout = document.createElement('p');\nout.appendChild(document.createTextNode(config.loading));\nform.appendChild(out);  \n\nIf both are strings we check of out is undefined. We will create a loading message and subsequently the list of search results later on and store them in this variable. So if out is defined, it\u2019ll be an old version of a search (as users will re-submit the form over and over again)  and we need to remove that old version.\n\nWe then create a paragraph with the loading message and append it to the form.\n\nvar APIurl = 'http://boss.yahooapis.com/ysearch/web/v1/' + \n\t\t\t\t\t\t\t\t\t\t\t\tterm + '?callback=SITESEARCH.found&sites=' + \n\t\t\t\t\t\t\t\t\t\t\t\tsite + '&count=' + config.results + \n\t\t\t\t\t\t\t\t\t\t\t\t'&appid=' + config.appID;\n\t\t\t\t\tvar s = document.createElement('script');\n\t\t\t\t\ts.setAttribute('src',APIurl);\n\t\t\t\t\ts.setAttribute('type','text/javascript');\n\t\t\t\t\tdocument.getElementsByTagName('head')[0].appendChild(s);\n\t\t\t\t\treturn false;\n\t\t\t\t}\n\t\t\t};\n\t\t}\n\t}\n};\n\nNow it is time to call the BOSS API by assembling a correct REST URL, create a script node and apply it to the head of the document. We return false to ensure the form does not get submitted as we want to stay on the page.\n\nNotice that we are using SITESEARCH.found as the callback method, which means that we need to define this one to deal with the data returned by the API.\n\nfunction found(o){\n\tvar list = document.createElement('ul');\n\tvar results = o.ysearchresponse.resultset_web;\n\tif(results){\n\t\tvar item,link,description;\n\nWe create a new list and then get the resultset_web array from the data returned from the API. If there aren\u2019t any results returned, this array will not exist which is why we need to check for it. Once we done that we can define three variables to repeatedly store the item title we want to display, the link to point to and the description of the link.\n\nfor(var i=0,j=results.length;i<j;i++){\n\titem = document.createElement('li');\n\tlink = document.createElement('a');\n\tlink.setAttribute('href',results[i].clickurl);\n\tlink.innerHTML = results[i].title;\n\titem.appendChild(link);\n\tdescription = document.createElement('p');\n\tdescription.innerHTML = results[i]['abstract'];\n\titem.appendChild(description);\n\tlist.appendChild(item);\n}\n\nWe then loop over the results array and assemble a list of results with the titles in links and paragraphs with the abstract of the site. Notice the bracket notation for abstract as abstract is a reserved word in JavaScript2 :).\n\n} else {\n\t\tlist = document.createElement('p');\n\t\tlist.appendChild(document.createTextNode(config.noresults));\n\t}\n\tform.replaceChild(list,out);\n\tout = list;\n};      \n\nIf there aren\u2019t any results, we define a paragraph with the no results message as list. In any case we replace the old out (the loading message) with the list and re-define out as the list.  \n\nreturn{\n\t\tconfig:config,\n\t\tinit:init,\n\t\tfound:found\n\t};\n}();\n\nAll that is left to do is return the properties and methods we want to make public. In this case found needs to be public as it is accessed by the API return. We return init to make it accessible and config to allow implementers to override any of the properties.\n\nUsing the script\n\n\nIn order to use this script, all you need to do is to add it after the form in the document, override the API key with your own and call init():\n\n<form id=\"customsearch\" action=\"http://search.yahoo.com/search\">\n\t<div>\n\t\t<label for=\"p\">Search this site:</label>\n\t\t<input type=\"text\" name=\"p\" id=\"term\">\n\t\t<input type=\"hidden\" name=\"vs\" id=\"site\" value=\"bbc.co.uk\">\n\t\t<input type=\"submit\" value=\"go\">\n\t</div>\n</form>\n<script type=\"text/javascript\" src=\"boss-site-search.js\"></script>\n<script type=\"text/javascript\">\n\tSITESEARCH.config.appID = 'copy-the-id-you-know-to-get-where';\n\tSITESEARCH.init();\n</script>\n\nWhere to go from here\n\nThis is just a very simple example of what you can do with BOSS. You can define languages and regions, retrieve and display images and news and mix the results with other data sources before displaying them. One very cool feature is that by adding a view=keyterms parameter to the URL you can get the keywords of each of the results to drill deeper into the search. An example for this written in PHP is available on the YDN blog.

{"rowid": 277, "title": "Raising the Bar on Mobile", "contents": "One of the primary challenges of designing for mobile devices is that screen real estate is often in limited supply. Through the advocacy of Luke W and others, we\u2019ve drawn comfort from the idea that this constraint ends up benefiting users and designers alike, from obvious advantages like portability and reach, to influencing our content strategy decisions through focus and restraint. But that doesn\u2019t mean we shouldn\u2019t take advantage of every last pixel of that screen we can snag!\n\nAs anyone who has designed a website for use on a smartphone can attest, there\u2019s an awful lot of space on mobile screens dedicated to browser functions that would be better off toggled out of view. Unfortunately, the visibility of some of these elements is beyond our control, such as the buttons fixed to the bottom of the viewport in iOS\u2019s Safari and the WebOS browser. However, in many devices, the address bar at the top can be manually hidden, and its absence frees up enough pixel room for a large, impactful heading, a critical piece of navigation, or even just a little more white space to air things out.\n\nSo, as my humble contribution to this most festive of web publications, today I\u2019ll dig into the approach I used to hide the address bar in a browser-agnostic fashion for sites like BostonGlobe.com, and the jQuery Mobile framework.\n\nSurveying the land\n\nFirst, let\u2019s assess the chromes of some popular, current mobile browsers. For example purposes, the following screen-captures feature the homepage of the Boston Globe site, without any address-bar-hiding logic in place.\n\nNote: these captures are just mockups \u2013 actual experience on these platforms may vary.\n\n On the left is iOS5\u2019s Safari (running on iPhone), and on the right is Windows Phone 7 (pre-Mango).\n\n BlackBerry 7 (left), and Android 2.3 (right).\n\n WebOS (left), Opera Mini (middle), and Opera Mobile (right).\n\nSome browsers, such the default browsers on WebOS and BlackBerry 5, hide the bar automatically without any developer intervention, but many of them don\u2019t. Of these, we can only manually hide the address bar on iOS Safari and Android (according to Opera Web Opener, Mike Taylor, some discussion is underway for support in Opera Mini and Mobile as well, which would be great!). This is unfortunate, but iOS and Android are incredibly popular, so let\u2019s direct our focus there.\n\nGreat API, or greatest API?\n\nAs it turns out, iOS and Android not only allow you to hide the address bar, they use the same JavaScript method to do so, too (this shouldn\u2019t be surprising, given that they are both WebKit browsers, but nothing expected happens in mobile). However, the method they use is not exactly intuitive. You might set out looking for a JavaScript API dedicated to this purpose, like, say, window.toolbar.hide(), but alas, to hide the address bar you need to use the window.scrollTo method!\n\nwindow.scrollTo(0, 0);\n\nThe scrollTo method is not new, it\u2019s just this particular use of it that is. For the uninitiated, scrollTo is designed to scroll a document to a particular set of coordinates, assuming the document is large enough to scroll to that spot. The method accepts two arguments: a left coordinate; and a top coordinate. It\u2019s both simple and supported well pretty much everywhere. In iOS and Android, these coordinates are calculated from the top of the browser\u2019s viewport, just below the address bar (interestingly, it seems that some platforms like BlackBerry 6 treat the top of the browser chrome as 0 instead, meaning the page content is closer to 20px from the top).\n\nAnyway, by passing the coordinates 0, 0 to the scrollTo method, the browser will jump to the top of the page and pull the address bar out of view! Of course, if a quick call to scrollTo was all we need to do to hide the address bar in iOS and Android, this article would be pretty short, and nothing new. Unfortunately, the first issue we need to deal with is that this method alone will not usually do the trick: it must be called after the page has finished loading.\n\nThe browser gives us a load event for just that purpose, so we\u2019ll wrap our scrollTo method in it and continue on our merry way! We\u2019ll use the standard, addEventListener method to bind the the load event, passing arguments for event name load, and a callback function to execute when the event is triggered.\n\nwindow.addEventListener(\"load\",function() {\n    window.scrollTo(0, 0);\n});\n\nFor the sake of preventing errors in those using browsers that don\u2019t support addEventListener, such as Internet Explorer 8 and under, let\u2019s make sure that method exists before we use it:\n\nif( window.addEventListener ){\n    window.addEventListener(\"load\",function() {\n        window.scrollTo(0, 0);\n    });\n}\n\nNow we\u2019re getting somewhere, but we must also call the method after the load event\u2019s default behavior has been applied. For this, we can use the setTimeout method, delaying its execution to after the load event has run its course.\n\nif( window.addEventListener ){\n    window.addEventListener(\"load\",function() {\n        setTimeout(function(){\n            window.scrollTo(0, 0);\n        }, 0);\n    });\n}\n\nSweet sugar of Christmas! Hit this demo in iOS and watch that address bar drift up and away!\n\nNot so fast\u2026\n\nWe\u2019ve got a little problem: the approach above does work in iOS but, in some cases, it works a little too well. In the process of applying this behavior, we\u2019ve broken one of the primary tenets of responsible web development: don\u2019t break the browser\u2019s default behaviour. This usability rule of thumb is often violated by developers with even the best of intentions, from breaking the browser\u2019s back button through unrecorded Ajax page refreshes, to fancy momentum touch scrolling scripts that can wreak havoc in all but the most sophisticated of devices. In this case, we\u2019ve prevented the browser\u2019s native support of deep-linking to sections of a page (a hash identifier in the URL matching a page element\u2019s id attribute, for example, http://example.com#contact) from working properly, because our script always scrolls to the top.\n\nTo avoid this collision, we\u2019ll need to detect whether a deep link, or hash, is present in the URL before applying our logic. We can do this by ensuring that the location.hash property is falsey:\n\nif( !window.location.hash && window.addEventListener ){\n    window.addEventListener( \"load\",function() {\n        setTimeout(function(){\n            window.scrollTo(0, 0);\n        }, 0);\n    });\n}\n\nStill works great! And a quick test using a hash-based URL confirms that our script will not execute when a deep anchor is in play. Now iOS is looking sharp, and we\u2019ve added our feature defensively to avoid conflicts.\n\n\n\nNow, on to Android\u2026\n\nWait. You didn\u2019t expect that we could write code for one browser and be finished, right? Of course you didn\u2019t. I mentioned earlier that Android uses the same method for getting rid of the scrollbar, but I left out the fact that the arguments it prefers vary slightly, but significantly, from iOS. Bah!\n\nDifferering from the earlier logic from iOS, to remove the address bar on Android\u2019s default browser, you need to pass a Y coordinate of 1 instead of 0. Aside from being just plain odd, this is particularly unfortunate because to any other browser on the planet, 1px is a very real, however small, distance from the top of the page!\n\nwindow.scrollTo( 0, 1 );\n\nLooks like we\u2019re going to need a fork\u2026\n\nR UA Android?\n\nAt this point, some developers might decide to simply not support this feature in Android, and more determined devs might decide that a quick check of the User Agent string would be a reliable way to determine the browser and tweak the scroll value accordingly. Neither of those decisions would be tragic, but in the spirit of cross-browser and future-friendly development, I\u2019ll propose an alternative.\n\nBy this point, it should be clear that neither of the implementations above offer a particularly intuitive way to hide an address bar. As such, one might be skeptical that these approaches will stick around very long in their present state in either browser. Perhaps at some point, Android will decide to use 0 like iOS, making our lives a little easier, or maybe some new browser will decide to model their address bar hiding method after one of these implementations. In any case, detecting the User Agent only allows us to apply logic based on the known present, and in the world of mobile, let\u2019s face it, the present is already the past.\n\nWriting a check\n\nIn this next step of today\u2019s technique, we\u2019ll apply some logic to quickly determine the behavior model of the browser we\u2019re using, then capitalize on that model \u2013 without caring which browser it happens to come from \u2013 by applying the appropriate scroll distance.\n\nTo do this, we\u2019ll rely on a fortunate side effect of Android\u2019s implementation, which is when you programatically scroll the page to 1 using scrollTo, Android will report that it\u2019s still at 0 because oddly enough, it is! Of course, any other browser in this situation will report a scroll distance of 1. Thus, by scrolling the page to 1, then asking the browser its scroll distance, we can use this artifact of their wacky implementation to our advantage and scroll to the location that makes sense for the browser in play.\n\nGetting the scroll distance\n\nTo pull off our test, we\u2019ll need to ask the browser for its current scroll distance. The methods for getting scroll distance are not entirely standardized across popular browsers, so we\u2019ll need to use some cross-browser logic. The following scroll distance function is similar to what you\u2019d find in a library like jQuery. It checks the few common ways of getting scroll distance before eventually falling back to 0 for safety\u2019s sake (that said, I\u2019m unaware of any browsers that won\u2019t return a numeric value from one of the first three properties).\n\n// scrollTop getter\nfunction getScrollTop(){\n    return scrollTop  = window.pageYOffset ||\ndocument.compatMode === \"CSS1Compat\" && document.documentElement.scrollTop ||\ndocument.body.scrollTop || 0;\n}\n\nIn order to execute that code above, the body object (referenced here as document.body) will need to be defined already, or we\u2019ll risk an error. To determine that it\u2019s defined, we can run a quick timer to execute code as soon as that object is defined and ready for use.\n\nvar bodycheck = setInterval(function(){\n    if( document.body ){\n        clearInterval( bodycheck );\n        //more logic can go here!!\n    }   \n}, 15 );\n\nAbove, we\u2019ve defined a 15 millisecond interval called bodycheck that checks if document.body is defined and, if so, clears itself of running again. Within that if statement, we can extend our logic further to run other code, such as our check for the scroll distance, defined via the variable scrollTop below:\n\nvar scrollTop,\n    bodycheck = setInterval(function(){\n    if( document.body ){\n        clearInterval( bodycheck );\n        scrollTop = getScrollTop();\n    }   \n}, 15 );\n\nWith this working, we can immediately scroll to 1, then check the scroll distance when the body is defined. If the distance reports 1, we\u2019re likely in a non-Android browser, so we\u2019ll scroll back to 0 and clean up our mess.\n\nwindow.scrollTo( 0, 1 );\n\nvar scrollTop,\n    bodycheck = setInterval(function(){\n    if( document.body ){\n        clearInterval( bodycheck );\n        scrollTop = getScrollTop();\n        window.scrollTo( 0, scrollTop === 1 ? 0 : 1 );\n    }   \n}, 15 );\n\nCashing in\n\nAll of the pieces are written now, so all we need to do is combine them with our previous logic for scrolling when the window is loaded, and we\u2019ll have a cross-browser solution of which John Resig would be proud. Here\u2019s our combined code snippet, with some formatting updates rolled in as well:\n\n(function( win ){\n\tvar doc = win.document;\n\n\t// If there\u2019s a hash, or addEventListener is undefined, stop here\n\tif( !location.hash && win.addEventListener ){\n\t\t//scroll to 1\n\t\twindow.scrollTo( 0, 1 );\n\t\tvar scrollTop = 1,\n\t\t\tgetScrollTop = function(){\n\t\t\t\treturn win.pageYOffset || doc.compatMode = \"CSS1Compat\" && doc.documentElement.scrollTop || doc.body.scrollTop || 0;\n\t\t\t},\n\t\t\t//reset to 0 on bodyready, if needed\n\t\t\tbodycheck = setInterval(function(){\n\t\t\t\tif( doc.body ){\n\t\t\t\t\tclearInterval( bodycheck );\n\t\t\t\t\tscrollTop = getScrollTop();\n\t\t\t\t\twin.scrollTo( 0, scrollTop = 1 ? 0 : 1 );\n\t\t\t\t}\t\n\t\t\t}, 15 );\n\t\twin.addEventListener( \u201cload\u201d, function(){\n\t\t\tsetTimeout(function(){\n\t\t\t\t\t//reset to hide addr bar at onload\n\t\t\t\t\twin.scrollTo( 0, scrollTop === 1 ? 0 : 1 );\n\t\t\t}, 0);\n\t\t} );\n\t}\n})( this );\nView code example\n\nAnd with that, we\u2019ve got a bunch more room to play with on both iOS and Android.\n\n\n\nBreak out the eggnog\n\n\u2026because we\u2019re not done yet! In the spirit of making our script act more defensively, there\u2019s still another use case to consider. It was essential that we used the window\u2019s load event to trigger our scripting, but on pages with a lot of content, its use can come at a cost. Often, a user will begin interacting with a page, scrolling down as they read, before the load event has fired. In those situations, our script will jump the user back to the top of the page, resulting in a jarring experience.\n\nTo prevent this problem from occurring, we\u2019ll need to ensure that the page has not been scrolled beyond a certain amount. We can add a simple check using our getScrollTop function again, this time ensuring that its value is not greater than 20 pixels or so, accounting for a small tolerance.\n\nif( getScrollTop() < 20 ){\n    //reset to hide addr bar at onload\n    window.scrollTo( 0, scrollTop === 1 ? 0 : 1 );\n}\n\nAnd with that, we\u2019re pretty well protected! Here\u2019s a final demo.\n\nThe completed script can be found on Github (full source: https://gist.github.com/1183357 ). It\u2019s MIT licensed. Feel free to use it anywhere or any way you\u2019d like!\n\nYour thoughts?\n\nI hope this article provides you with a browser-agnostic approach to hiding the address bar that you can use in your own projects today. Perhaps alternatively, the complications involved in this approach convinced you that doing this well is more trouble than it\u2019s worth and, depending on the use case, that could be a fair decision. But at the very least, I hope this demonstrates that there\u2019s a lot of work involved in pulling off this small task in only two major platforms, and that there\u2019s a real need for standardization in this area.\n\nFeel free to leave a comment or criticism and I\u2019ll do my best to answer in a timely fashion.\n\nThanks, everyone!\n\nSome parting notes\n\nI scream, you scream\u2026\n\nAt the time of writing, I was not able to test this method on the latest Android 4.0 (Ice Cream Sandwich) build. According to Sencha Touch\u2019s browser scorecard, the browser in 4.0 may have a different way of managing the address bar, so I\u2019ll post in the comments once I get a chance to dig into it further.\n\nShort pages get no love\n\nToday\u2019s technique only works when the page is as tall, or taller than, the device\u2019s available screen height, so that the address bar may be scrolled out of view. On a short page, you might work around this issue by applying a minimum height to the body element ( body { min-height: 460px; } ), but given the variety of screen sizes out there, not to mention changes in orientation, it\u2019s tough to find a value that makes much sense (unless you manipulate it with JavaScript).", "year": "2011", "author": "Scott Jehl", "author_slug": "scottjehl", "published": "2011-12-20T00:00:00+00:00", "url": "https://24ways.org/2011/raising-the-bar-on-mobile/", "topic": "design"}
{"rowid": 158, "title": "10 Ways To Get Design Approval", "contents": "One of the most challenging parts of the web design process is getting design sign off. It can prove time consuming, demoralizing and if you are not careful can lead to a dissatisfied client. What is more you can end up with a design that you are ashamed to include in your portfolio.\n\nHow then can you ensure that the design you produce is the one that gets built? How can you get the client to sign off on your design? Below are 10 tips learnt from years of bitter experience.\n\n1. Define the role of the client and designer\n\nMany of the clients you work with will not have been involved in a web project before. Even if they have they may have worked in a very different way to what you would expect. Take the time at the beginning of the project to explain their role in the design of the site.\n\nThe best approach is to emphasis that their job is to focus on the needs of their users and business. They should concentrate on the broad issues, while you worry about the details of layout, typography and colour scheme.\n\nBy clarifying what you expect from the client, you help them to provide the right kind of input throughout the process.\n\n2. Understand the business\n\nBefore you open up Photoshop or put pen to paper, take the time to make sure you properly understand not only the brief but the organization behind the site. By understanding their business objectives, organizational structure and marketing strategy your design decisions will be better informed.\n\nYou cannot rely upon the brief to provide all of the information you need. It is important to dig deeper and get as good an understanding of their business as possible. This information will prove invaluable when justifying your design decisions.\n\n3. Understand the users\n\nWe all like to think of ourselves as user centric designers, but exactly how much effort do you put into knowing your users before beginning the design process?\n\nTake the time to really understand them the best you can. Try to meet with some real prospective users and get to know their needs. Failing that work with the client to produce user personas to help picture exactly what kind of people they are. \n\nUnderstanding your users not only improves the quality of your work, but also helps move the discussion away from the personal preferences of the client, to the people who\u2019s opinion really matters.\n\n4. Avoid multiple concepts\n\nMany clients like the idea of having the option to choose between multiple design concepts. However, although on the surface this might appear to be a good idea it can ultimately be counterproductive for design sign off.\n\nIn a world of limited budgets it is unwise to waste money on producing designs that are ultimately going to be thrown away. The resources would be better spent refining a single design through multiple iterations.\n\nWhat is more, multiple concepts often cause confusion rather than clarity. It is common for a client to request one element from one design and another from the second. As any designer knows this seldom works.\n\n5. Use mood boards\n\nClients are often better at expressing what they don\u2019t like than what they do. This is one of the reasons why they favour producing multiple design concepts. An alternative less costly approach is to create a series of mood boards. These boards contain a collection of colours, typography and imagery which represent different \u201cmoods\u201d or directions, which the design could take. \n\nMood boards are quick and easy to produce allowing you to try out various design approaches with the client without investing the time needed to produce complete design concepts. This means that by the time you develop a concept the client and designer have already established an understanding about the direction of the design.\n\n6. Say what you like\n\nIt is not uncommon for a client to ask for a design that looks similar to another site they like. The problem is that it can often be hard to establish exactly what it is about the site that attracts them. Also in many cases the sites they like are not something you are keen to emulate!\n\nA better approach that was suggested to me by Andy Budd is to show them sites that you think the design should emulate. Keep a collection of screen captures from well designed sites and pick out a few that are relevant to that particular client. Explain why you feel these designs might suit their project and ask for their feedback. If they don\u2019t like your choices then expose them to more of your collection and see what they pick out.\n\n7. Wireframe the homepage\n\nOften clients find it hard to distinguish between design and content and so sometimes reject a design on the basis that the content is not right. This is particularly true when signing off the homepage.\n\nYou may therefore find it useful to establish the homepage content before producing the design. That way once they see the design they will not be distracted by the content. One of the best ways to do this is by producing a basic wireframe consisting of a series of content boxes. Once this has been approved you will find the sign off of design much easier.\n\n8. Present your designs\n\nAlthough it is true that a good design should speak for itself it still needs presenting to the client. The client needs to understand why you have made the design decisions you have, otherwise they will judge the design purely on personal preference. \n\nTalk them through the design explaining how it meets the needs of their users and business objectives. Refer to the mood boards and preferred sites the client approved and explain how the design is a continuation of those. Never simply email the design through and hope the client interprets your work correctly!\n\n9. Provide written supporting material\n\nUnfortunately, no matter how well you justify the design to the client he is almost certain to want to show it to others. He may need his bosses approval or require internal buy in. At the very least he is going to want to get a second opinion from a friend or colleague.\n\nThe problem with this is that you are not going to be there to present to these people in the same way you did for the client. You cannot expect the client to present your ideas as well as you did. The reality is that you have lost control of how the design is perceived.\n\nOne way to minimize this problem is to provide written documentation supporting the design. This can be a summary of the presentation you gave to the client and allows him to distribute this along with the design. By putting a written explanation with the design you ensure that everybody who sees it gets the same message.\n\n10. Control the feedback\n\nMy final piece of advice for managing design sign off is to control the way you receive feedback. A clients natural inclination will be to give you his personal opinion on the design. This is reinforced because you ask them what they think of the design. Instead ask them what their users will think of the design. Encourage them to think from the users perspective.\n\nAlso encourage them to keep that overarching focus I talked about in my first tip. Their tendency will be to try to improve the design, however that should be your problem not theirs. The role of a client should be to defend the needs of their users and business not do the design. Encourage the client to make comments such as \u201cI am not sure that my female users will like the masculine colours\u201d rather than \u201ccan we make the whole design pink.\u201d It is down to them to identify the problems and for you as the designer to find the most appropriate solution.\n\nSo there you have it.

{"rowid": 157, "title": "Capturing Caps Lock", "contents": "One of the more annoying aspects of having to remember passwords (along with having to remember loads of them) is that if you\u2019ve got Caps Lock turned on accidentally when you type one in, it won\u2019t work, and you won\u2019t know why. Most desktop computers alert you in some way if you\u2019re trying to enter your password to log on and you\u2019ve enabled Caps Lock; there\u2019s no reason why the web can\u2019t do the same. What we want is a warning \u2013 maybe the user wants Caps Lock on, because maybe their password is in capitals \u2013 rather than something that interrupts what they\u2019re doing. Something subtle.\n\nBut that doesn\u2019t answer the question of how to do it. Sadly, there\u2019s no way of actually detecting whether Caps Lock is on directly. However, there\u2019s a simple work-around; if the user presses a key, and it\u2019s a capital letter, and they don\u2019t have the Shift key depressed, why then they must have Caps Lock on! Simple. \n\nDOM scripting allows your code to be notified when a key is pressed in an element; when the key is pressed, you get the ASCII code for that key. Capital letters, A to Z, have ASCII codes 65 to 90. So, the code would look something like:\n\non a key press\n\tif the ASCII code for the key is between 65 and 90 *and* if shift is pressed\n\t\twarn the user that they have Caps Lock on, but let them carry on\n\tend if\nend keypress\n\nThe actual JavaScript for this is more complicated, because both event handling and keypress information differ across browsers. Your event handling functions are passed an event object, except in Internet Explorer where you use the global event object; the event object has a which parameter containing the ASCII code for the key pressed, except in Internet Explorer where the event object has a keyCode parameter; some browsers store whether the shift key is pressed in a shiftKey parameter and some in a modifiers parameter. All this boils down to code that looks something like this:\n\nkeypress: function(e) {\n\tvar ev = e ? e : window.event;\n\tif (!ev) {\n\t\treturn;\n\t}\n\tvar targ = ev.target ? ev.target : ev.srcElement;\n\t// get key pressed\n\tvar which = -1;\n\tif (ev.which) {\n\t\twhich = ev.which;\n\t} else if (ev.keyCode) {\n\t\twhich = ev.keyCode;\n\t}\n\t// get shift status\n\tvar shift_status = false;\n\tif (ev.shiftKey) {\n\t\tshift_status = ev.shiftKey;\n\t} else if (ev.modifiers) {\n\t\tshift_status = !!(ev.modifiers & 4);\n\t}\n\n\t// At this point, you have the ASCII code in \u201cwhich\u201d, \n\t// and shift_status is true if the shift key is pressed\n}\n\nThen it\u2019s just a check to see if the ASCII code is between 65 and 90 and the shift key is pressed. (You also need to do the same work if the ASCII code is between 97 (a) and 122 (z) and the shift key is not pressed, because shifted letters are lower-case if Caps Lock is on.)\n\nif (((which >= 65 && which <= 90) && !shift_status) || \n\t((which >= 97 && which <= 122) && shift_status)) {\n\t// uppercase, no shift key\n\t/* SHOW THE WARNING HERE */\n} else {\n\t/* HIDE THE WARNING HERE */\n}\n\nThe warning can be implemented in many different ways: highlight the password field that the user is typing into, show a tooltip, display text next to the field. For simplicity, this code shows the warning as a previously created image, with appropriate alt text. Showing the warning means creating a new <img> tag with DOM scripting, dropping it into the page, and positioning it so that it\u2019s next to the appropriate field. The image looks like this:\n\n\n\nYou know the position of the field the user is typing into (from its offsetTop and offsetLeft properties) and how wide it is (from its offsetWidth properties), so use createElement to make the new img element, and then absolutely position it with style properties so that it appears in the appropriate place (near to the text field). \n\nThe image is a transparent PNG with an alpha channel, so that the drop shadow appears nicely over whatever else is on the page. Because Internet Explorer version 6 and below doesn\u2019t handle transparent PNGs correctly, you need to use the AlphaImageLoader technique to make the image appear correctly.\n\nnewimage = document.createElement('img');\nnewimage.src = \"http://farm3.static.flickr.com/2145/2067574980_3ddd405905_o_d.png\";\nnewimage.style.position = \"absolute\";\nnewimage.style.top = (targ.offsetTop - 73) + \"px\";\nnewimage.style.left = (targ.offsetLeft + targ.offsetWidth - 5) + \"px\";\nnewimage.style.zIndex = \"999\";\nnewimage.setAttribute(\"alt\", \"Warning: Caps Lock is on\");\nif (newimage.runtimeStyle) {\n\t// PNG transparency for IE\n\tnewimage.runtimeStyle.filter += \"progid:DXImageTransform.Microsoft.AlphaImageLoader(src='http://farm3.static.flickr.com/2145/2067574980_3ddd405905_o_d.png',sizingMethod='scale')\";\n}\ndocument.body.appendChild(newimage);\n\nNote that the alt text on the image is also correctly set. Next, all these parts need to be pulled together. On page load, identify all the password fields on the page, and attach a keypress handler to each. (This only needs to be done for password fields because the user can see if Caps Lock is on in ordinary text fields.)\n\nvar inps = document.getElementsByTagName(\"input\");\nfor (var i=0, l=inps.length; i\n\nThe \u201ccreate an image\u201d code from above should only be run if the image is not already showing, so instead of creating a newimage object, create the image and attach it to the password field so that it can be checked for later (and not shown if it\u2019s already showing). For safety, all the code should be wrapped up in its own object, so that its functions don\u2019t collide with anyone else\u2019s functions. So, create a single object called capslock and make all the functions be named methods of the object:\n\nvar capslock = {\n\t... \n\tkeypress: function(e) {\n\t}\n\t...\n}\n\nAlso, the \u201ccreate an image\u201d code is saved into its own named function, show_warning(), and the converse \u201cremove the image\u201d code into hide_warning(). This has the advantage that developers can include the JavaScript library that has been written here, but override what actually happens with their own code, using something like:\n\n<script src=\"jscapslock.js\" type=\"text/javascript\"></script>\n<script type=\"text/javascript\">\n\tcapslock.show_warning(target) {\n\t\t// do something different here to warn the user\n\t}\n\tcapslock.hide_warning(target) {\n\t\t// hide the warning that we created in show_warning() above\n\t}\n</script>\n\nAnd that\u2019s all. Simply include the JavaScript library in your pages, override what happens on a warning if that\u2019s more appropriate for what you\u2019re doing, and that\u2019s all you need.\n\n See the script in action.", "year": "2007", "author": "Stuart Langridge", "author_slug": "stuartlangridge", "published": "2007-12-04T00:00:00+00:00", "url": "https://24ways.org/2007/capturing-caps-lock/", "topic": "code"}
{"rowid": 49, "title": "Universal React", "contents": "One of the libraries to receive a huge amount of focus in 2015 has been ReactJS, a library created by Facebook for building user interfaces and web applications.\nMore generally we\u2019ve seen an even greater rise in the number of applications built primarily on the client side with most of the logic implemented in JavaScript. One of the main issues with building an app in this way is that you immediately forgo any customers who might browse with JavaScript turned off, and you can also miss out on any robots that might visit your site to crawl it (such as Google\u2019s search bots). Additionally, we gain a performance improvement by being able to render from the server rather than having to wait for all the JavaScript to be loaded and executed.\nThe good news is that this problem has been recognised and it is possible to build a fully featured client-side application that can be rendered on the server. The way in which these apps work is as follows:\n\nThe user visits www.yoursite.com and the server executes your JavaScript to generate the HTML it needs to render the page.\nIn the background, the client-side JavaScript is executed and takes over the duty of rendering the page.\nThe next time a user clicks, rather than being sent to the server, the client-side app is in control.\nIf the user doesn\u2019t have JavaScript enabled, each click on a link goes to the server and they get the server-rendered content again.\n\nThis means you can still provide a very quick and snappy experience for JavaScript users without having to abandon your non-JS users. We achieve this by writing JavaScript that can be executed on the server or on the client (you might have heard this referred to as isomorphic) and using a JavaScript framework that\u2019s clever enough handle server- or client-side execution. Currently, ReactJS is leading the way here, although Ember and Angular are both working on solutions to this problem.\nIt\u2019s worth noting that this tutorial assumes some familiarity with React in general, its syntax and concepts. If you\u2019d like a refresher, the ReactJS docs are a good place to start.\n\u00a0Getting started\nWe\u2019re going to create a tiny ReactJS application that will work on the server and the client. First we\u2019ll need to create a new project and install some dependencies. In a new, blank directory, run:\nnpm init -y\nnpm install --save ejs express react react-router react-dom\nThat will create a new project and install our dependencies:\n\nejs is a templating engine that we\u2019ll use to render our HTML on the server.\nexpress is a small web framework we\u2019ll run our server on.\nreact-router is a popular routing solution for React so our app can fully support and respect URLs.\nreact-dom is a small React library used for rendering React components.\n\nWe\u2019re also going to write all our code in ECMAScript 6, and therefore need to install BabelJS and configure that too.\nnpm install --save-dev babel-cli babel-preset-es2015 babel-preset-react\nThen, create a .babelrc file that contains the following:\n{\n  \"presets\": [\"es2015\", \"react\"]\n}\nWhat we\u2019ve done here is install Babel\u2019s command line interface (CLI) tool and configured it to transform our code from ECMAScript 6 (or ES2015) to ECMAScript 5, which is more widely supported. We\u2019ll need the React transforms when we start writing JSX when working with React.\nCreating a server\nFor now, our ExpressJS server is pretty straightforward. All we\u2019ll do is render a view that says \u2018Hello World\u2019. Here\u2019s our server code:\nimport express from 'express';\nimport http from 'http';\n\nconst app = express();\n\napp.use(express.static('public'));\n\napp.set('view engine', 'ejs');\n\napp.get('*', (req, res) => {\n  res.render('index');\n});\n\nconst server = http.createServer(app);\n\nserver.listen(3003);\nserver.on('listening', () => {\n  console.log('Listening on 3003');\n});\nHere we\u2019re using ES6 modules, which I wrote about on 24 ways last year, if you\u2019d like a reminder. We tell the app to render the index view on any GET request (that\u2019s what app.get('*') means, the wildcard matches any route).\nWe now need to create the index view file, which Express expects to be defined in views/index.ejs:\n<!DOCTYPE html>\n<html>\n  <head>\n    <title>My App</title>\n  </head>\n\n  <body>\n    Hello World\n  </body>\n</html>\nFinally, we\u2019re ready to run the server. Because we installed babel-cli earlier we have access to the babel-node executable, which will transform all your code before running it through node. Run this command:\n./node_modules/.bin/babel-node server.js\nAnd you should now be able to visit http://localhost:3003 and see \u2018Hello World\u2019 right there:\n\nBuilding the React app\nNow we\u2019ll build the React application entirely on the server, before adding the client-side JavaScript right at the end. Our app will have two routes, / and /about which will both show a small amount of content. This will demonstrate how to use React Router on the server side to make sure our React app plays nicely with URLs.\nFirstly, let\u2019s update views/index.ejs. Our server will figure out what HTML it needs to render, and pass that into the view. We can pass a value into our view when we render it, and then use EJS syntax to tell it to output that data. Update the template file so the body looks like so:\n<body>\n  <%- markup %>\n</body>\nNext, we\u2019ll define the routes we want our app to have using React Router. For now we\u2019ll just define the index route, and not worry about the /about route quite yet. We could define our routes in JSX, but I think for server-side rendering it\u2019s clearer to define them as an object. Here\u2019s what we\u2019re starting with:\nconst routes = {\n  path: '',\n  component: AppComponent,\n  childRoutes: [\n    {\n      path: '/',\n      component: IndexComponent\n    }\n  ]\n}\nThese are just placed at the top of server.js, after the import statements. Later we\u2019ll move these into a separate file, but for now they are fine where they are.\nNotice how I define first that the AppComponent should be used at the '' path, which effectively means it matches every single route and becomes a container for all our other components. Then I give it a child route of /, which will match the IndexComponent. Before we hook these routes up with our server, let\u2019s quickly define components/app.js and components/index.js. app.js looks like so:\nimport React from 'react';\n\nexport default class AppComponent extends React.Component {\n  render() {\n    return (\n      <div>\n        <h2>Welcome to my App</h2>\n        { this.props.children }\n      </div>\n    );\n  }\n}\nWhen a React Router route has child components, they are given to us in the props under the children key, so we need to include them in the code we want to render for this component. The index.js component is pretty bland:\nimport React from 'react';\n\nexport default class IndexComponent extends React.Component {\n  render() {\n    return (\n      <div>\n        <p>This is the index page</p>\n      </div>\n    );\n  }\n}\nServer-side routing with React Router\nHead back into server.js, and firstly we\u2019ll need to add some new imports:\nimport React from 'react';\nimport { renderToString } from 'react-dom/server';\nimport { match, RoutingContext } from 'react-router';\n\nimport AppComponent from './components/app';\nimport IndexComponent from './components/index';\nThe ReactDOM package provides react-dom/server which includes a renderToString method that takes a React component and produces the HTML string output of the component. It\u2019s this method that we\u2019ll use to render the HTML from the server, generated by React. From the React Router package we use match, a function used to find a matching route for a URL; and RoutingContext, a React component provided by React Router that we\u2019ll need to render. This wraps up our components and provides some functionality that ties React Router together with our app. Generally you don\u2019t need to concern yourself about how this component works, so don\u2019t worry too much.\nNow for the good bit: we can update our app.get('*') route with the code that matches the URL against the React routes:\napp.get('*', (req, res) => {\n  // routes is our object of React routes defined above\n  match({ routes, location: req.url }, (err, redirectLocation, props) => {\n    if (err) {\n      // something went badly wrong, so 500 with a message\n      res.status(500).send(err.message);\n    } else if (redirectLocation) {\n      // we matched a ReactRouter redirect, so redirect from the server\n      res.redirect(302, redirectLocation.pathname + redirectLocation.search);\n    } else if (props) {\n      // if we got props, that means we found a valid component to render\n      // for the given route\n      const markup = renderToString(<RoutingContext {...props} />);\n\n      // render `index.ejs`, but pass in the markup we want it to display\n      res.render('index', { markup })\n\n    } else {\n      // no route match, so 404. In a real app you might render a custom\n      // 404 view here\n      res.sendStatus(404);\n    }\n  });\n});\nWe call match, giving it the routes object we defined earlier and req.url, which contains the URL of the request. It calls a callback function we give it, with err, redirectLocation and props as the arguments. The first two conditionals in the callback function just deal with an error occuring or a redirect (React Router has built in redirect support). The most interesting bit is the third conditional, else if (props). If we got given props and we\u2019ve made it this far it means we found a matching component to render and we can use this code to render it:\n...\n} else if (props) {\n  // if we got props, that means we found a valid component to render\n  // for the given route\n  const markup = renderToString(<RoutingContext {...props} />);\n\n  // render `index.ejs`, but pass in the markup we want it to display\n  res.render('index', { markup })\n} else {\n   ...\n}\nThe renderToString method from ReactDOM takes that RoutingContext component we mentioned earlier and renders it with the properties required. Again, you need not concern yourself with what this specific component does or what the props are. Most of this is data that React Router provides for us on top of our components.\nNote the {...props}, which is a neat bit of JSX syntax that spreads out our object into key value properties. To see this better, note the two pieces of JSX code below, both of which are equivalent:\n<MyComponent a=\"foo\" b=\"bar\" />\n\n// OR:\n\nconst props = { a: \"foo\", b: \"bar\" };\n<MyComponent {...props} />\nRunning the server again\nI know that felt like a lot of work, but the good news is that once you\u2019ve set this up you are free to focus on building your React components, safe in the knowledge that your server-side rendering is working. To check, restart the server and head to http://localhost:3003 once more. You should see it all working!\n\nRefactoring and one more route\nBefore we move on to getting this code running on the client, let\u2019s add one more route and do some tidying up. First, move our routes object out into routes.js:\nimport AppComponent from './components/app';\nimport IndexComponent from './components/index';\n\nconst routes = {\n  path: '',\n  component: AppComponent,\n  childRoutes: [\n    {\n      path: '/',\n      component: IndexComponent\n    }\n  ]\n}\n\nexport { routes };\nAnd then update server.js. You can remove the two component imports and replace them with:\nimport { routes } from './routes';\nFinally, let\u2019s add one more route for ./about and links between them. Create components/about.js:\nimport React from 'react';\n\nexport default class AboutComponent extends React.Component {\n  render() {\n    return (\n      <div>\n        <p>A little bit about me.</p>\n      </div>\n    );\n  }\n}\nAnd then you can add it to routes.js too:\nimport AppComponent from './components/app';\nimport IndexComponent from './components/index';\nimport AboutComponent from './components/about';\n\nconst routes = {\n  path: '',\n  component: AppComponent,\n  childRoutes: [\n    {\n      path: '/',\n      component: IndexComponent\n    },\n    {\n      path: '/about',\n      component: AboutComponent\n    }\n  ]\n}\n\nexport { routes };\nIf you now restart the server and head to http://localhost:3003/about` you\u2019ll see the about page!\n\nFor the finishing touch we\u2019ll use the React Router link component to add some links between the pages. Edit components/app.js to look like so:\nimport React from 'react';\nimport { Link } from 'react-router';\n\nexport default class AppComponent extends React.Component {\n  render() {\n    return (\n      <div>\n        <h2>Welcome to my App</h2>\n        <ul>\n          <li><Link to='/'>Home</Link></li>\n          <li><Link to='/about'>About</Link></li>\n        </ul>\n        { this.props.children }\n      </div>\n    );\n  }\n}\nYou can now click between the pages to navigate. However, everytime we do so the requests hit the server. Now we\u2019re going to make our final change, such that after the app has been rendered on the server once, it gets rendered and managed in the client, providing that snappy client-side app experience.\nClient-side rendering\nFirst, we\u2019re going to make a small change to views/index.ejs. React doesn\u2019t like rendering directly into the body and will give a warning when you do so. To prevent this we\u2019ll wrap our app in a div:\n<body>\n  <div id=\"app\"><%- markup %></div>\n  <script src=\"build.js\"></script>\n</body>\nI\u2019ve also added in a script tag to build.js, which is the file we\u2019ll generate containing all our client-side code.\nNext, create client-render.js. This is going to be the only bit of JavaScript that\u2019s exclusive to the client side. In it we need to pull in our routes and render them to the DOM.\nimport React from 'react';\nimport ReactDOM from 'react-dom';\nimport { Router } from 'react-router';\n\nimport { routes } from './routes';\n\nimport createBrowserHistory from 'history/lib/createBrowserHistory';\n\nReactDOM.render(\n  <Router routes={routes} history={createBrowserHistory()} />,\n  document.getElementById('app')\n)\nThe first thing you might notice is the mention of createBrowserHistory. React Router is built on top of the history module, a module that listens to the browser\u2019s address bar and parses the new location. It has many modes of operation: it can keep track using a hashbang, such as http://localhost/#!/about (this is the default), or you can tell it to use the HTML5 history API by calling createBrowserHistory, which is what we\u2019ve done. This will keep the URLs nice and neat and make sure the client and the server are using the same URL structure. You can read more about React Router and histories in the React Router documentation.\nFinally we use ReactDOM.render and give it the Router component, telling it about all our routes, and also tell ReactDOM where to render, the #app element.\nGenerating build.js\nWe\u2019re actually almost there! The final thing we need to do is generate our client side bundle. For this we\u2019re going to use webpack, a module bundler that can take our application, follow all the imports and generate one large bundle from them. We\u2019ll install it and babel-loader, a webpack plugin for transforming code through Babel.\nnpm install --save-dev webpack babel-loader\nTo run webpack we just need to create a configuration file, called webpack.config.js. Create the file in the root of our application and add the following code:\nvar path = require('path');\nmodule.exports = {\n  entry: path.join(process.cwd(), 'client-render.js'),\n  output: {\n    path: './public/',\n    filename: 'build.js'\n  },\n  module: {\n    loaders: [\n      {\n        test: /.js$/,\n        loader: 'babel'\n      }\n    ]\n  }\n}\nNote first that this file can\u2019t be written in ES6 as it doesn\u2019t get transformed. The first thing we do is tell webpack the main entry point for our application, which is client-render.js. We use process.cwd() because webpack expects an exact location \u2013 if we just gave it the string \u2018client-render.js\u2019, webpack wouldn\u2019t be able to find it.\nNext, we tell webpack where to output our file, and here I\u2019m telling it to place the file in public/build.js. Finally we tell webpack that every time it hits a file that ends in .js, it should use the babel-loader plugin to transform the code first.\nNow we\u2019re ready to generate the bundle!\n./node_modules/.bin/webpack\nThis will take a fair few seconds to run (on my machine it\u2019s about seven or eight), but once it has it will have created public/build.js, a client-side bundle of our application. If you restart your server once more you\u2019ll see that we can now navigate around our application without hitting the server, because React on the client takes over. Perfect!\nThe first bundle that webpack generates is pretty slow, but if you run webpack -w it will go into watch mode, where it watches files for changes and regenerates the bundle. The key thing is that it only regenerates the small pieces of the bundle it needs, so while the first bundle is very slow, the rest are lightning fast. I recommend leaving webpack constantly running in watch mode when you\u2019re developing.\nConclusions\nFirst, if you\u2019d like to look through this code yourself you can find it all on GitHub. Feel free to raise an issue there or tweet me if you have any problems or would like to ask further questions.\nNext, I want to stress that you shouldn\u2019t use this as an excuse to build all your apps in this way. Some of you might be wondering whether a static site like the one we built today is worth its complexity, and you\u2019d be right. I used it as it\u2019s an easy example to work with but in the future you should carefully consider your reasons for wanting to build a universal React application and make sure it\u2019s a suitable infrastructure for you.\nWith that, all that\u2019s left for me to do is wish you a very merry Christmas and best of luck with your React applications!", "year": "2015", "author": "Jack Franklin", "author_slug": "jackfranklin", "published": "2015-12-05T00:00:00+00:00", "url": "https://24ways.org/2015/universal-react/", "topic": "code"}
{"rowid": 47, "title": "Developing Robust Deployment Procedures", "contents": "Once you have developed your site, how do you make it live on your web hosting? For many years the answer was to log on to your server and upload the files via FTP. Over time most hosts and FTP clients began to support SFTP, ensuring your files were transmitted over a secure connection. The process of deploying a site however remained the same.\n\nThere are issues with deploying a site in this way. You are essentially transferring files one by one to the server without any real management of that transfer. If the transfer fails for some reason, you may end up with a site that is only half updated. It can then be really difficult to work out what hasn\u2019t been replaced or added, especially where you are updating an existing site. If you are updating some third-party software your update may include files that should be removed, but that may not be obvious to you and you risk leaving outdated files littering your file system. Updating using (S)FTP is a fragile process that leaves you open to problems caused by both connectivity and human error. Is there a better way to do this?\n\nYou\u2019ll be glad to know that there is. A modern professional deployment workflow should have you moving away from fragile manual file transfers to deployments linked to code committed into source control.\n\nThe benefits of good practice\n\nYou may never have experienced any major issues while uploading files over FTP, and good FTP clients can help. However, there are other benefits to moving to modern deployment practices.\n\nNo surprises when you launch\n\nIf you are deploying in the way I suggest in this article you should have no surprises when you launch because the code you committed from your local environment should be the same code you deploy \u2013 and to staging if you have a staging server. A missing vital file won\u2019t cause things to start throwing errors on updating the live site.\n\nBeing able to work collaboratively\n\nSource control and good deployment practice makes working with your clients and other developers easy. Deploying first to a staging server means you can show your client updates and then push them live. If you subcontract some part of the work, you can give your subcontractor the ability to deploy to staging, leaving you with the final push to launch, once you know you are happy with the work.\n\nHaving a proper backup of site files with access to them from anywhere\n\nThe process I will outline requires the use of hosted, external source control. This gives you a backup of your latest commit and the ability to clone those files and start working on them from any machine, wherever you are.\n\nBeing able to jump back into a site quickly when the client wants a few changes\n\nWhen doing client work it is common for some work to be handed over, then several months might go by without you needing to update the site. If you don\u2019t have a good process in place, just getting back to work on it may take several hours for what could be only a few hours of work in itself. A solid method for getting your local copy up to date and deploying your changes live can cut that set-up time down to a few minutes.\n\nThe tool chain\n\nIn the rest of this article I assume that your current practice is to deploy your files over (S)FTP, using an FTP client. You would like to move to a more robust method of deployment, but without blowing apart your workflow and spending all Christmas trying to put it back together again. Therefore I\u2019m selecting the most straightforward tools to get you from A to B.\n\nSource control\n\nPerhaps you already use some kind of source control for your sites. Today that is likely to be Git but you might also use Subversion or Mercurial. If you are not using any source control at all then I would suggest you choose Git, and that is what I will be working with in this article.\n\nWhen you work with Git, you always have a local repository. This is where your changes are committed. You also have the option to push those changes to a remote repository; for example, GitHub. You may well have come across GitHub as somewhere you can go to download open source code. However, you can also set up private repositories for sites whose code you don\u2019t want to make publicly accessible.\n\nA hosted Git repository gives you somewhere to push your commits to and deploy from, so it\u2019s a crucial part of our tool chain.\n\nA deployment service\n\nOnce you have your files pushed to a remote repository, you then need a way to deploy them to your staging environment and live server. This is the job of a deployment service.\n\nThis service will connect securely to your hosting, and either automatically (or on the click of a button) transfer files from your Git commit to the hosting server. If files need removing, the service should also do this too, so you can be absolutely sure that your various environments are the same.\n\nTools to choose from\n\nWhat follows are not exhaustive lists, but any of these should allow you to deploy your sites without FTP.\n\nHosted Git repositories\n\n\n\tGitHub\n\tBeanstalk\n\tBitbucket\n\n\nStandalone deployment tools\n\n\n\tDeploy\n\tdploy.io\n\tFTPloy\n\n\nI\u2019ve listed Beanstalk as a hosted Git repository, though it also includes a bundled deployment tool. Dploy.io is a standalone version of that tool just for deployment. In this tutorial I have chosen two separate services to show how everything fits together, and because you may already be using source control. If you are setting up all of this for the first time then using Beanstalk saves having two accounts \u2013 and I can personally recommend them.\n\nPutting it all together\n\nThe steps we are going to work through are:\n\n\n\tGetting your local site into a local Git repository\n\tPushing the files to a hosted repository\n\tConnecting a deployment tool to your web hosting\n\tSetting up a deployment\n\n\nGet your local site into a local Git repository\n\nDownload and install Git for your operating system.\n\nOpen up a Terminal window and tell Git your name using the following command (use the name you will set up on your hosted repository).\n\n> git config --global user.name \"YOUR NAME\"\n\n\nUse the next command to give Git your email address. This should be the address that you will use to sign up for your remote repository.\n\n> git config --global user.email \"YOUR EMAIL ADDRESS\"\n\n\nStaying in the command line, change to the directory where you keep your site files. If your files are in /Users/rachel/Sites/mynicewebite you would type:\n\n> cd /Users/rachel/Sites/mynicewebsite\n\n\nThe next command tells Git that we want to create a new Git repository here.\n\n> git init\n\n\nWe then add our files:\n\n> git add .\n\n\nThen commit the files:\n\n> git commit -m \u201cAdding initial files\u201d\n\n\nThe bit in quotes after -m is a message describing what you are doing with this commit. It\u2019s important to add something useful here to remind yourself later why you made the changes included in the commit.\n\nYour local files are now in a Git repository! However, everything should be just the same as before in terms of working on the files or viewing them in a local web server. The only difference is that you can add and commit changes to this local repository.\n\nWant to know more about Git? There are some excellent resources in a range of formats here.\n\nSetting up a hosted Git repository\n\nI\u2019m going to use Atlassian Bitbucket for my first example as they offer a free hosted and private repository.\n\nCreate an account on Bitbucket. Then create a new empty repository and give it a name that will identify the repository easily.\n\nClick Getting Started and under Command Line select \u201cI have an existing project\u201d. This will give you a set of instructions to run on the command line. The first instruction is just to change into your working directory as we did before. We then add a remote repository, and run two commands to push everything up to Bitbucket.\n\ncd /path/to/my/repo\ngit remote add origin https://myuser@bitbucket.org/myname/24ways-tutorial.git\ngit push -u origin --all \ngit push -u origin --tags \n\n\nWhen you run the push command you will be asked for the password that you set for Bitbucket. Having entered that, you should be able to view the files of your site on Bitbucket by selecting the navigation option Source in the sidebar.\n\nYou will also be able to see commits. When we initially committed our files locally we added the message \u201cAdding initial files\u201d. If you select Commits from the sidebar you\u2019ll see we have one commit, with the message we set locally. You can imagine how useful this becomes when you can look back and see why you made certain changes to a project that perhaps you haven\u2019t worked on for six months.\n\nBefore working on your site locally you should run:\n\n> git pull\n\n\nin your working directory to make sure you have all of the most up-to-date files. This is especially important if someone else might work on them, or you just use multiple machines.\n\nYou then make your changes and add any changed or modified files, for example:\n\n> git add index.php\n\n\nCommit the change locally:\n\n> git commit -m \u201cupdated the homepage\u201d\n\n\nThen push it to Bitbucket:\n\n> git push origin master\n\n\nIf you want to work on your files on a different computer you clone them using the following command:\n\n> git clone https://myuser@bitbucket.org/myname/24ways-tutorial.git\n\n\nYou then have a copy of your files that is already a Git repository with the Bitbucket repository set up as a remote, so you are all ready to start work.\n\nConnecting a deployment tool to your repository and web hosting\n\nThe next step is deploying files. I have chosen to use a deployment tool called Deploy as it has support for Bitbucket. It does have a monthly charge \u2013 but offers a free account for open source projects.\n\nSign up for your account then log in and create your first project. Select Create an empty project. Under Configure Repository Details choose Bitbucket and enter your username and password.\n\nIf Deploy can connect, it will show you your list of projects. Select the one you want.\n\nThe next screen is Add New Server and here you need to configure the server that you want to deploy to. You might set up more than one server per project. In an ideal world you would deploy to a staging server for your client preview changes and then deploy once everything is signed off. For now I\u2019ll assume you just want to set up your live site.\n\nGive the server a name; I usually use Production for the live web server. Then choose the protocol to connect with. Unless your host really does not support SFTP (which is pretty rare) I would choose that instead of FTP.\n\nYou now add the same details your host gave you to log in with your SFTP client, including the username and password. The Path on server should be where your files are on the server. When you log in with an SFTP client and you get put in the directory above public_html then you should just be able to add public_html here.\n\nOnce your server is configured you can deploy. Click Deploy now and choose the server you just set up. Then choose the last commit (which will probably be selected for you) and click Preview deployment. You will then get a preview of which files will change if you run the deployment: the files that will be added and any that will be removed. At the very top of that screen you should see the commit message you entered right back when you initially committed your files locally.\n\nIf all looks good, run the deployment.\n\nYou have taken the first steps to a more consistent and robust way of deploying your websites. It might seem like quite a few steps at first, but you will very soon come to realise how much easier deploying a live site is through this process.\n\nYour new procedure step by step\n\n\n\tEdit your files locally as before, testing them through a web server on your own computer.\n\tCommit your changes to your local Git repository.\n\tPush changes to the remote repository.\n\tLog into the deployment service.\n\tHit the Deploy now button.\n\tPreview the changes.\n\tRun the deployment and then check your live site.\n\n\nTaking it further\n\nI have tried to keep things simple in this article because so often, once you start to improve processes, it is easy to get bogged down in all the possible complexities. If you move from deploying with an FTP client to working in the way I have outlined above, you\u2019ve taken a great step forward in creating more robust processes. You can continue to improve your procedures from this point.\n\nStaging servers for client preview\n\nWhen we added our server we could have added an additional server to use as a staging server for clients to preview their site on. This is a great use of a cheap VPS server, for example. You can set each client up with a subdomain \u2013 clientname.yourcompany.com \u2013 and this becomes the place where they can view changes before you deploy them.\n\nIn that case you might deploy to the staging server, let the client check it out and then go back and deploy the same commit to the live server.\n\nUsing Git branches\n\nAs you become more familiar with using Git, and especially if you start working with other people, you might need to start developing using branches. You can then have a staging branch that deploys to staging and a production branch that is always a snapshot of what has been pushed to production. This guide from Beanstalk explains how this works.\n\nAutomatic deployment to staging\n\nI wouldn\u2019t suggest doing automatic deployment to the live site. It\u2019s worth having someone on hand hitting the button and checking that everything worked nicely. If you have configured a staging server, however, you can set it up to deploy the changes each time a commit is pushed to it.\n\nIf you use Bitbucket and Deploy you would create a deployment hook on Bitbucket to post to a URL on Deploy when a push happens to deploy the code. This can save you a few steps when you are just testing out changes. Even if you have made lots of changes to the staging deployment, the commit that you push live will include them all, so you can do that manually once you are happy with how things look in staging.\n\nFurther Reading\n\n\n\tThe tutorials from Git Client Tower, already mentioned in this article, are a great place to start if you are new to Git.\n\tA presentation from Liam Dempsey showing how to use the GitHub App to connect to Bitbucket\n\tTry Git from Code School\n\tThe Git Workbook a self study guide to Git from Lorna Mitchell\n\n\nGet set up for the new year\n\nI love to start the New Year with a clean slate and improved processes. If you are still wrangling files with FTP then this is one thing you could tick off your list to save you time and energy in 2015.

{"rowid": 312, "title": "Preparing to Be Badass Next Year", "contents": "Once we\u2019ve eaten our way through the holiday season, people will start to think about new year\u2019s resolutions. We tend to focus on things that we want to change\u2026 and often things that we don\u2019t like about ourselves to \u201cfix\u201d. We set rules for ourselves, or try to start new habits or stop bad ones. We focus in on things we will or won\u2019t do. \nFor many of us the list of things we \u201cought\u201d to be spending time on is just plain overwhelming \u2013 family, charity/community, career, money, health, relationships, personal development. \nIt\u2019s kinda scary even just listing it out, isn\u2019t it? I want to encourage you to think differently about next year.\nThe ever-brilliant Kathy Sierra articulates a better approach really well when talking about the attitude we should have to building great products. She tells us to think not about what the user will do with our product, but about what they are trying to achieve in the real world and how our product helps them to be badass1.\nWhen we help the user be badass, then we are really making a difference. \nI suppose this is one way of saying: focus not on what you will do, focus on what it will help you achieve. How will it help you be awesome?\nIn what ways do you want to be more badass next year?\nA professional lens\nThough of course you might want to focus in on health or family or charity or community or another area next year, many people will want to become more badass in their chosen career. \nSo let\u2019s talk about a scaffold to help you figure out your professional / career development next year. \nFirst up, an assumption: everyone wants to be awesome. Nobody gets up in the morning aiming to be crap at their job. Nobody thinks to themselves \u201cToday I am aiming for just south of mediocre, and if I can mess up everybody else\u2019s ability to do good work then that will be just perfect2\u201d. \nErgo, you want to be awesome. So what does awesome look like? \nDanger!\nThe big trap that people fall into when think about their professional development is to immediately focus on the things that they aren\u2019t good at. When you ask people \u201cwhat do you want to work on getting better at next year?\u201d they frequently gravitate to the things that they believe they are bad at. \nWhy is this a trap? Because if you focus all your time and energy on improving the areas that you suck at, you are going to end up middling at everything. Going from bad \u2192 mediocre at a given skill / behaviour takes a bunch of time and energy. So if you spend all your time going from bad \u2192 mediocre at things, what do you think you end up? That\u2019s right, mediocre. \nMediocrity is not a great career goal, kids. \nWhat do you already rock at?\nThe much better investment of time and energy is to go from good \u2192 awesome. It often takes the same amount of relative time and energy, but wow the end result is better! So first, ask yourself and those who know you well what you are already pretty damn good at. Combat imposter syndrome by asking others. \nThen figure out how to double down on those things. What does brilliant look like for a given skill? What\u2019s the knowledge or practice that you need to level yourself up even further in that thing?\nBut what if I really really suck?\nAdmittedly, sometimes something you suck at really is holding you back. But it\u2019s important to separate out weaknesses (just something you suck at) from controlling weaknesses (something you suck at that actually matters for your chosen career). \nIf skill x is just not an important thing for you to be good at, you may never need to care that you aren\u2019t good at it. If your current role or the one you aspire to next really really requires you to be great at x, then it\u2019s worth investing your time and energy (and possibly money too) getting better at it.\nSo when you look at the things that you aren\u2019t good at, which of those are actually essential for success?\nThe right ratio\nA good rule of thumb is to pick three things you are already good at to work on becoming awesome at and limit yourself to one weakness that you are trying to improve on. That way you are making sure that you get to awesome in areas where you already have an advantage, and limit the amount of time you are spending on going from bad \u2192 mediocre. \nLevelling up learning\nSo once you\u2019ve figured out your areas you want to focus on next year, what do you actually decide to do? \nMost of all, you should try to design your day-to-day work in a way that it is also an effective learning experience. This means making sure you have a good feedback loop \u2013 you get to try something, see if it works, learn from it, rinse and repeat. \nIt\u2019s also about balance: you want to be challenged enough for work to be interesting, without it being so hard it\u2019s frustrating. You want to do similar / the same things often enough that you get to learn and improve, without it being so repetitive that it\u2019s boring. \nContinuously getting better at things you are already good at is actually both easier and harder than it sounds. The advantage is that it\u2019s pretty easy to add the feedback loop to make sure that you are improving; the disadvantage is that you\u2019re already good at these skills so you could easily just \u201cdo\u201d without ever stopping to reflect and improve. Build in time for personal retrospectives (\u201cWhat went well? What didn\u2019t? What one thing will I choose to change next time?\u201d) and find a way of getting feedback from outside sources as well. \nAs for the new skills, it\u2019s worth knowing that skill development follows a particular pattern:\n\nWe all start out unconsciously incompetent (we don\u2019t know what to do and if we tried we\u2019d unwittingly get it wrong), progress on to conscious incompetence (we now know we\u2019re doing it wrong) then conscious competence (we\u2019re doing it right but wow it takes effort and attention) and eventually get to unconscious competence (automatically getting it right). \nYour past experiences and knowledge might let you move faster through these stages, but no one gets to skip them. Invest the time and remember you need the feedback loop to really improve. \nWhat about keeping up?\nEverything changes very fast in our industry. We need to invest in not falling behind, in keeping on top of what great looks like. There are a bunch of ways to do this, from reading blog posts, following links on Twitter, reading books to attending conferences or workshops, or just finding time to build things in new ways or with new technologies. \nWhich will work best for you depends on how you best learn. Do you prefer to swallow a book? Do you learn most by building or experimenting? \nWhatever your learning style though, remember that there are three real needs:\n\nScan the landscape (what\u2019s changing, does it matter)\nGain the knowledge or skills (get the detail)\nApply the knowledge or skills (use it in reality)\n\nWhen you remember that you need all three of these things it can help you get more of what you do. \nFor me personally, I use a combination of conferences and blogs / Twitter to scan the landscape. Half of what I want out of a conference is just a list of things to have on my radar that might become important. I then pick a couple of things to go read up on more (I personally learn most effectively by swallowing a book or spec or similar). And then I pick one thing at a time to actually apply in real life, to embed the skill / knowledge. \nIn summary\n\nAim to be awesome (mediocrity is not a career goal).\nFigure out what you already rock at.\nOnly care about stuff you suck at that matters for your career.\nPick three things to go from good \u2192 awesome and one thing to go from bad \u2192 mediocre (or mediocre \u2192 good) this year.\nDesign learning into your daily work.\nScan the landscape, learn new stuff, apply it for real. \nBe badass!\n\n\n\n\n\nShe wrote a whole book about it. You should read it: Badass: Making Users Awesome\u00a0\u21a9\n\n\nBefore you argue too vehemently: I suppose some antisocial sociopathic bastards do exist.

{"rowid": 280, "title": "Conditional Loading for Responsive Designs", "contents": "On the eighteenth day of last year\u2019s 24 ways,  Paul Hammond  wrote a great article called Speed Up Your Site with Delayed Content. He outlined a technique for loading some content \u2014 like profile avatars \u2014 after the initial page load. This gives you a nice performance boost.\n\nThere\u2019s another situation where this kind of delayed loading could be really handy: mobile-first responsive design.\n\nResponsive design combines three techniques:\n\n\n\ta fluid grid\n\tflexible images\n\tmedia queries\n\n\nAt first, responsive design was applied to existing desktop-centric websites to allow the layout to adapt to smaller screen sizes. But more recently it has been combined with another innovative approach called mobile first.\n\nRather then starting with the big, bloated desktop site and then scaling down for smaller devices, it makes more sense to start with the constraints of the small screen and then scale up for larger viewports. Using this approach, your layout grid, your large images and your media queries are applied on top of the pre-existing small-screen design. It\u2019s taking progressive enhancement to the next level.\n\nOne of the great advantages of the mobile-first approach is that it forces you to really focus on the core content of your page. It might be more accurate to think of this as a content-first approach. You don\u2019t have the luxury of sidebars or multiple columns to fill up with content that\u2019s just nice to have rather than essential.\n\nBut what happens when you apply your media queries for larger viewports and you do have sidebars and multiple columns? Well, you can load in that nice-to-have content using the same kind of Ajax functionality that Paul described in his article last year. The difference is that you first run a quick test to see if the viewport is wide enough to accommodate the subsidiary content. This is conditional delayed loading.\n\nConsider this situation: I\u2019ve published an article about cats and I\u2019d like to include relevant cat-related news items in the sidebar \u2026but only if there\u2019s enough room on the screen for a sidebar.\n\nI\u2019m going to use Google\u2019s News API to return the search results. This is the ideal time to use delayed loading: I don\u2019t want a third-party service slowing down the rendering of my page so I\u2019m going to fire off the request after my document has loaded.\n\nHere\u2019s an example of the kind of Ajax function that I would write:\n\nvar searchNews = function(searchterm) {\n\tvar elem = document.createElement('script');\n\telem.src = 'http://ajax.googleapis.com/ajax/services/search/news?v=1.0&q='+searchterm+'&callback=displayNews';\n\tdocument.getElementsByTagName('head')[0].appendChild(elem);\n};\n\nI\u2019ve provided a callback function called displayNews that takes the JSON result of that Ajax request and adds it an element on the page with the ID newsresults:\n\nvar displayNews = function(news) {\n\tvar html = '',\n\titems = news.responseData.results,\n\ttotal = items.length;\n\tif (total>0) {\n\t\tfor (var i=0; i<total; i++) {\n\t\t\tvar item = items[i];\n\t\t\thtml+= '<article>';\n\t\t\thtml+= '<a href=\"'+item.unescapedUrl+'\">';\n\t\t\thtml+= '<h3>'+item.titleNoFormatting+'</h3>';\n\t\t\thtml+= '</a>';\n\t\t\thtml+= '<p>';\n\t\t\thtml+= item.content;\n\t\t\thtml+= '</p>';\n\t\t\thtml+= '</article>';\n\t\t}\n\t\tdocument.getElementById('newsresults').innerHTML = html;\n\t}\n};\n\nNow, I can call that function at the bottom of my document:\n\n<script>\n    searchNews('cats');\n</script>\n\nIf I only want to run that search when there\u2019s room for a sidebar, I can wrap it in an if statement:\n\n<script>\nif (document.documentElement.clientWidth > 640) {\n    searchNews('cats');\n}\n</script>\n\nIf the browser is wider than 640 pixels, that will fire off a search for news stories about cats and put the results into the newsresults element in my markup:\n\n<div id=\"newsresults\">\n    <!-- search results go here -->\n</div>\n\nThis works pretty well but I\u2019m making an assumption that people with small-screen devices wouldn\u2019t be interested in seeing that nice-to-have content. You know what they say about assumptions: they make an ass out of you and umptions. I should really try to give everyone at least the option to get to that extra content:\n\n<div id=\"newsresults\">\n    <a href=\"http://www.google.com/search?q=cats&tbm=nws\">Search Google News</a>\n</div>\n\nSee the result\n\nVisitors with small-screen devices will see that link to the search results; visitors with larger screens will get the search results directly.\n\nI\u2019ve been concentrating on HTML and JavaScript, but this technique has consequences for content strategy and information architecture. Instead of thinking about possible page content in a binary way as either \u2018on the page\u2019 or \u2018not on the page\u2019, conditional loading introduces a third \u2018it\u2019s complicated\u2019 option.\n\nThis was just a simple example but I hope it illustrates that conditional loading could become an important part of the content-first responsive design approach.", "year": "2011", "author": "Jeremy Keith", "author_slug": "jeremykeith", "published": "2011-12-02T00:00:00+00:00", "url": "https://24ways.org/2011/conditional-loading-for-responsive-designs/", "topic": "ux"}
{"rowid": 286, "title": "Defending the Perimeter Against Web Widgets", "contents": "On July 14, 1789, citizens of Paris stormed the Bastille, igniting a revolution that toppled the French monarchy. On July 14 of this year, there was a less dramatic (though more tweeted) takedown: The Deck network, which delivers advertising to some of the most popular web design and culture destinations, was down for about thirty minutes. During this period, most partner sites running ads from The Deck could not be viewed as result.\n\nA few partners were unaffected (aside from not having an ad to display). Fortunately, Dribbble, was one of them. In this article, I\u2019ll discuss outages like this and how to defend against them. But first, a few qualifiers: The Deck has been rock solid \u2013 this is the only downtime we\u2019ve witnessed since joining in June. More importantly, the issues in play are applicable to any web widget you might add to your site to display third-party content.\n\nDown and out\n\nYour defense is only as good as its weakest link. Web pages are filled with links, some of which threaten the ability of your page to load quickly and correctly. If you want your site to work when external resources fail, you need to identify the weak links on your site. In this article, we\u2019ll talk about web widgets as a point of failure and defensive JavaScript techniques for handling them.\n\nWidgets 101\n\nImagine a widget that prints out a Pun of the Day on your site. A simple technique for both widget provider and consumer is for the provider to expose a URL:\n\nhttp://widgetjonesdiary.com/punoftheday.js\n\nwhich returns a JavaScript file like this:\n\ndocument.write(\"<h2>The Pun of the Day</h2><p>Where do frogs go for beers after work? Hoppy hour!</p>\");\n\nThe call to document.write() injects the string passed into the document where it is called. So to display the widget on your page, simply add an external script tag where you want it to appear:\n\n<div class=\"punoftheday\">\n  <script src=\"http://widgetjonesdiary.com/punoftheday.js\"></script>\n  <!-- Content appears here as output of script above -->\n</div>\n\nThis approach is incredibly easy for both provider and consumer. But there are implications\u2026\n\ndocument.write()\u2026 or wrong?\n\nAs in the example above, scripts may perform a document.write() to inject HTML. Page rendering halts while a script is processed so any output can be inlined into the document. Therefore, page rendering speed depends on how fast the script returns the data. If an external JavaScript widget hangs, so does the page content that follows. It was this scenario that briefly stalled partner sites of The Deck last summer.\n\nThe elegant solution\n\nTo make our web widget more robust, calls to document.write() should be avoided. This can be achieved with a technique called JSONP (AKA JSON with padding). In our example, instead of writing inline with document.write(), a JSONP script passes content to a callback function:\n\npublishPun(\"<h2>Pun of the Day</h2><p>Where do frogs go for beers after work? Hoppy hour!</p>\");\n\nThen, it\u2019s up to the widget consumer to implement a callback function responsible for displaying the content. Here\u2019s a simple example where our callback uses jQuery to write the content into a target <div>:\n\n<!-- Where widget content should appear -->\n<div class=\"punoftheday\"></div>\n\n\u2026\n\n\n<br />\nfunction publishPun(content) {\n  $(&#8216;.punoftheday&#8217;).html(content); // Writes content display location<br />\n}<br />\n\n\n\n\nView Example 1\n\nEven if the widget content appears at the top of the page, our script can be included at the bottom so it\u2019s non-blocking: a slow response leaves page rendering unaffected. It simply invokes the callback which, in turn, writes the widget content to its display destination.\n\nThe hack\n\nBut what to do if your provider doesn\u2019t support JSONP? This was our case with The Deck. Returning to our example, I\u2019m reminded of computer scientist David Wheeler\u2019s statement, \u201cAll problems in computer science can be solved by another level of indirection\u2026 Except for the problem of too many layers of indirection.\u201d\n\nIn our case, the indirection is to move the widget content into position after writing it to the page. This allows us to place the widget <script> tag at the bottom of the page so rendering won\u2019t be blocked, but still display the widget in the target. The strategy:\n\n\n\tLoad widget content into a hidden <div> at the bottom of the page.\n\tMove the loaded content from the hidden <div> to its display location.\n\n\nand the code:\n\n<!-- Where widget content should appear -->\n<div class=\"punoftheday\"></div>\n\n\u2026\n\n\n\n  \n  \n\n\n\n<br />\n$(&#8216;.punoftheday&#8217;).append($(&#8216;.loading-dock&#8217;).children(&#8216;:gt(0)&#8217;));<br />\n\nView Example 2\n\nAfter the external punoftheday.js script has processed, the rendered HTML will look as follows:\n\n<div class=\"loading-dock hidden\">\n  <script src=\"http://widgetjonesdiary.com/punoftheday.js\"></script>\n  <h2>Pun of the Day</h2>\n  <p>Where do frogs go for beers after work? Hoppy hour!</p>\n</div>\n\nThe \u2018loading-dock\u2019 <div> now includes the widget content, albeit hidden from view (if we\u2019ve styled the \u2018hidden\u2019 class with display: none). There\u2019s just one more step: move the content to its display destination. This line of jQuery (from above) does the trick:\n\n$('.punoftheday').append($('.loading-dock').children(':gt(0)'));\n\nThis selects all child elements in the \u2018loading-doc\u2019 <div> except the first \u2013 the widget <script> tag which generated it \u2013 and moves it to the display destination. Worth noting is the :gt(0) jQuery selector extension, which allows us to exclude the first (in a 0-based array) child element \u2013 the widget <script> tag \u2013 from selection.\n\nSince all of this happens at the bottom of the page, just before the </body> tag, no rendering has to wait on the external widget script. The only thing that fails if our widget hangs is\u2026 the widget itself. Our weakest link has been strengthened and so has our site.

{"rowid": 5, "title": "Managing a Mind", "contents": "On 21 May 2013, I woke in a hospital bed feeling exhausted, disorientated and ashamed. The day before, I had tried to kill myself.\n\nIt\u2019s very hard to write about this and share it. It feels like I\u2019m opening up the deepest recesses of my soul and laying everything bare, but I think it\u2019s important we share this as a community. Since starting tentatively to write about my experience, I\u2019ve had many conversations about this: sharing with others; others sharing with me. I\u2019ve been surprised to discover how many people are suffering similarly, thinking that they\u2019re alone. They\u2019re not.\n\nDue to an insane schedule of teaching, writing, speaking, designing and just generally trying to keep up, I reached a point where my buffers completely overflowed. I was working so hard on so many things that I was struggling to maintain control. I was living life on fast-forward and my grasp on everything was slowly slipping.\n\nOn that day, I reached a low point \u2013 the lowest point of my life \u2013 and in that moment I could see only one way out. I surrendered. I can\u2019t really describe that moment. I\u2019m still grappling with it. All I know is that I couldn\u2019t take it any more and I gave up.\n\nI very nearly died.\n\nI\u2019m very fortunate to have survived. I was admitted to hospital, taken there unconscious in an ambulance. On waking, I felt overwhelmed with shame and overcome with remorse, but I was resolved to grasp the situation and address it. The experience has forced me to confront a great deal of issues in my life; it has also encouraged me to seek a deeper understanding of my situation and, in particular, the mechanics of the mind.\n\nThe relentless pace of change\n\nWe work in a fast-paced industry: few others, if any, confront the daily challenges we face. The landscape we work within is characterised by constant flux. It\u2019s changing and evolving at a rate we have never experienced before. Few industries reinvent themselves yearly, monthly, weekly\u2026 Ours is one of these industries. Technology accelerates at an alarming rate and keeping abreast of this change is challenging, to say the least.\n\nAs designers it can be difficult to maintain a knowledge bank that is relevant and fit for purpose. We\u2019re on a constant rollercoaster of endless learning, trying to maintain the pace as, daily, new ideas and innovations emerge \u2014 in some cases fundamentally changing our medium.\n\nUnder the pressure of client work or product design and development, it can be difficult to find the time to focus on learning the new skills we need to remain relevant and functionally competent. The result, all too often, is that the edges of our days have eroded. We no longer work nine to five; instead we work eight to six, and after the working day is over we regroup to spend our evenings learning. It\u2019s an unsustainable situation.\n\nFrom the workshop to the web\n\nAdded to this pressure to keep up, our work is now undertaken under a global gaze, conducted under an ever-present spotlight. Tools like Dribbble, Twitter and others, while incredibly powerful, have an unfortunate side effect, that of unfolding your ideas in public. This shift, from workshop to web, brings with it additional pressure.\n\nIn the past, the early stages of creativity took place within the relative safety of the workshop, an environment where one could take risks and gather feedback from a trusted few. We had space to make and space to break. No more. Our industry\u2019s focus (and society\u2019s focus) on sharing, leads us now to play out our decisions in public. This shift has changed us culturally, slowly but surely easing every aspect of our process \u2013 and lives \u2013 from private to public. This is at once liberating and debilitating.\n\nIf you\u2019re not careful, an addiction to followers, likes, retweets, page views and other forms of measurement can overwhelm you. When you release your work into the wild and all it\u2019s greeted with is silence, it can cripple you.\n\nReflecting on this, in an insightful article titled Derailed, Rogie King asks, \u201cCan social popularity take us off the course of growth and where we were intended to go?\u201d He makes a powerful point, that perhaps we might focus on what really matters, setting aside statistics. He concludes that to grow as practitioners we might be best served by seeking out critique through other avenues, away from the social spotlight.\n\nOn status anxiety and impostor syndrome\n\nFollowing my experience I embarked on a period of self-reflection. I wanted to discover what had driven me to take the course of action I had. I wanted to ensure it never happened again. I wanted to understand how the mind works and, in so doing, learn a little more about myself.\n\nI\u2019ve only begun this journey, but two things I discovered resonated with me: the twin pressures of status anxiety and impostor syndrome.\n\nIn his excellent book Status Anxiety, the philosopher Alain de Botton explores a growing concern with status anxiety, a worry about how others perceive us and how this shapes our relationship with the world. He states:\n\n\n\tWe all worry about what others think of us. We all long to succeed and fear failure. We all suffer \u2013 to a greater or lesser degree, usually privately and with embarrassment \u2013 from status anxiety. [\u2026] This is an almost universal anxiety that rarely gets mentioned directly: an anxiety about what others think of us; about whether we\u2019re judged a success or a failure, a winner or a loser.\n\n\nWe see these pressures played out and amplified in the social sphere we all inhabit. We are social animals and we cannot help but react to the landscape we live and work within. Even if your work receives the public praise you so secretly desire, you find yourself questioning this praise.\n\nA psychological phenomenon in which sufferers are unable to internalise their accomplishments, impostor syndrome is far more widespread than you\u2019d imagine. The author Leigh Buchanan describes it as \u201cA fear that one is not as smart or capable as others think.\u201d As she puts it, \u201cPeople who feel like frauds chalk up their accomplishments to external factors such as luck and timing, or worry they are coasting on charm and personality rather than on talent.\u201d\n\nAt the bottom, this was all I could see. I felt overwhelmed by others\u2019 perception of me. Was I a success or a failure? Would I be discovered as the fraud I\u2019d convinced myself that I was? These twin pressures \u2013 that I was unconscious of at the time \u2013 had lead me to a place of crippling self-doubt, questioning my very existence.\n\nThe act of discovery, of investigating how the mind functions, led me to a deeper understanding of myself. Developing an awareness of psychology and learning about conditions like status anxiety and impostor syndrome helped me to understand and recognise how my mind worked, enabling me to manage it more effectively.\n\n\n\nMake it count\n\nReflecting upon my experience, I began to regroup, to focus on what really mattered. I\u2019d taken on too much \u2014 as I believe many of us do. I was guilty of wanting to do all the things. I started to introduce pauses. Before blindly saying yes to everything, I forced myself to pause and ask: \u201cIs this important?\u201d\n\nOur community offers us huge benefits, but an always-on culture in which we\u2019re bombarded daily by opportunity places temptation in our paths. It\u2019s easy to get sucked in to a vortex of wanting to be a part of everything. It\u2019s important, however, to focus. As Simon Collison puts it:\n\n\n\tI cull and surrender topics. Then I focus on my strengths, mastering my core skills.\n\n\nWe only have so much time and we can only do so much. It\u2019s impossible, indeed futile, to try to do everything. Sometimes we need to step back a little and just enjoy life, enjoy others\u2019 achievements, without feeling the need to be actively involved ourselves.\n\nAs Mahatma Ghandi put it:\n\nA \u2018no\u2019 uttered from deepest conviction is better and greater than a \u2018yes\u2019 merely uttered to please, or what is worse, to avoid trouble.\nYoung India, volume 9, 1927\n\n\nWe need to learn to say no a little more often. We need to focus on the work that matters. This, coupled with an understanding of the mind and how it works, can help us achieve a happier balance between work and life.\n\nDon\u2019t waste your time. You only have one life.

What\u2019s that mean?\n\nUnobtrusive Degradable Ajax Style Sheet Switcher!\n\nBoy are you in for treat today \u2018cause we\u2019re gonna have a whole lotta Ajaxifida Unobtrucitosity CSS swappin\u2019 Fun!\n\nOkay are you really kidding? Nope. I\u2019ve even impressed myself on this one. Unfortunately, I don\u2019t have much time to tell you the ins and outs of what I actually did to get this to work. We\u2019re talking JavaScript, CSS, PHP\u2026Ajax. But don\u2019t worry about that. I\u2019ve always believed that a good A.P.I. is an invisible A.P.I\u2026 and this I felt I achieved. The only thing you need to know is how it works and what to do.\n\nA Quick Introduction Anyway\u2026\n\nFirst of all, the idea is very simple. I wanted something just like what Paul Sowden put together in \nAlternative Style: Working With Alternate Style Sheets from Alistapart Magazine EXCEPT a few minor (not-so-minor actually) differences which I\u2019ve listed briefly below:\n\n\n\n\tAllow users to switch styles without JavaScript enabled (degradable)\n\tPreventing the F.O.U.C. before the window \u2018load\u2019 when getting preferred styles\n\tKeep the JavaScript entirely off our markup (no onclick\u2019s or onload\u2019s)\n\tMake it very very easy to implement (ok, Paul did that too)\n\n\nWhat I did to achieve this was used server-side cookies instead of JavaScript cookies. Hence, PHP. However this isn\u2019t a \u201cPHP style switcher\u201d \u2013 which is where Ajax comes in. For the extreme technical folks, no, there is no xml involved here, or even a callback response. I only say Ajax because everyone knows what \u2018it\u2019 means. With that said, it\u2019s the Ajax that sets the cookies \u2018on the fly\u2019. Got it? Awesome!\n\nWhat you need\n\nLuckily, I\u2019ve done the work for you. It\u2019s all packaged up in a nice zip file (at the end\u2026keep reading for now) \u2013 so from here on out, \njust follow these instructions\n\nAs I\u2019ve mentioned, one of the things we\u2019ll be working with is PHP. So, first things first, open up a file called index and save it with a \u2018.php\u2019 extension.\n\nNext, place the following text at the top of your document (even above your DOCTYPE)\n\n<?php\n require_once('utils/style-switcher.php');\n // style sheet path[, media, title, bool(set as alternate)]\n $styleSheet = new AlternateStyles();\n $styleSheet->add('css/global.css','screen,projection'); // [Global Styles]\n $styleSheet->add('css/preferred.css','screen,projection','Wog Standard'); // [Preferred Styles]\n $styleSheet->add('css/alternate.css','screen,projection','Tiny Fonts',true); // [Alternate Styles]\n $styleSheet->add('css/alternate2.css','screen,projection','Big O Fonts',true); // // [Alternate Styles]\n $styleSheet->getPreferredStyles();\n ?>\n\nThe way this works is REALLY EASY. Pay attention closely.\n\nNotice in the first line we\u2019ve included our style-switcher.php file.\n\nNext we instantiate a PHP class called AlternateStyles() which will allow us to configure our style sheets. \nSo for kicks, let\u2019s just call our object $styleSheet\n\nAs part of the AlternateStyles object, there lies a public method called add. So naturally with our $styleSheet object, we can call it to (da \u2013 da-da-da!) Add Style Sheets!\n\nHow the add() method works\n\nThe add method takes in a possible four arguments, only one is required. However, you\u2019ll want to add some\u2026 since the whole point is working with alternate style sheets.\n\n$path can simply be a uri, absolute, or relative path to your style sheet. $media adds a media attribute to your style sheets. $title gives a name to your style sheets (via title attribute).$alternate (which shows boolean) simply tells us that these are the alternate style sheets.\n\nadd() Tips\n\nFor all global style sheets (meaning the ones that will always be seen and will not be swapped out), simply use the add method as shown next to // [Global Styles].\n\nTo add preferred styles, do the same, but add a \u2018title\u2019.\n\nTo add the alternate styles, do the same as what we\u2019ve done to add preferred styles, but add the extra boolean and set it to true.\n\nNote following when adding style sheets\n\n\n\tMultiple global style sheets are allowed\n\tYou can only have one preferred style sheet (That\u2019s a browser rule)\n\tFeel free to add as many alternate style sheets as you like\n\n\nMoving on\n\nSimply add the following snippet to the <head> of your web document:\n\n<script type=\"text/javascript\" src=\"js/prototype.js\"></script>\n <script type=\"text/javascript\" src=\"js/common.js\"></script>\n <script type=\"text/javascript\" src=\"js/alternateStyles.js\"></script>\n <?php\n $styleSheet->drop();\n ?>\n\nNothing much to explain here. Just use your copy & paste powers.\n\nHow to Switch Styles\n\nWhether you knew it or not, this baby already has the built in \u2018ubobtrusive\u2019 functionality that lets you switch styles by the drop of any link with a class name of \u2018altCss\u2018. Just drop them where ever you like in your document as follows:\n\n<a class=\"altCss\" href=\"index.php?css=Bog_Standard\">Bog Standard</a>\n <a class=\"altCss\" href=\"index.php?css=Really_Small_Fonts\">Small Fonts</a>\n <a class=\"altCss\" href=\"index.php?css=Large_Fonts\">Large Fonts</a>\n\nTake special note where the file is linking to. Yep. Just linking right back to the page we\u2019re on. The only extra parameters we pass in is a variable called \u2018css\u2019 \u2013 and within that we append the names of our style sheets.\n\nAlso take very special note on the names of the style sheets have an under_score to take place of any spaces we might have.\n\nGo ahead\u2026 play around and change the style sheet on the example page. Try disabling JavaScript and refreshing your browser. Still works!\n\nCool eh?\n\nWell, I put this together in one night so it\u2019s still a work in progress and very beta. If you\u2019d like to hear more about it and its future development, be sure stop on by my site where I\u2019ll definitely be maintaining it.\n\nDownload the beta anyway\n\nWell this wouldn\u2019t be fun if there was nothing to download.

{"rowid": 285, "title": "Composing the New Canon: Music, Harmony, Proportion", "contents": "Ohne Musik w\u00e4re das Leben ein Irrtum\n\u2014Friedrich NIETZSCHE, G\u00f6tzen-D\u00e4mmerung, Spr\u00fcche und Pfeile 33, 1889\n\n\nSomehow, music is hardcoded in human beings. It is something we understand and respond to without prior knowledge. Music exercises the emotions and our imaginative reflex, not just our hearing. It behaves so much like our emotions that music can seem to symbolize them, to bear them from one person to another. Not surprisingly, it conjures memories: the word music derives from Greek \u03bc\u03bf\u03c5\u03c3\u03b9\u03ba\u03ae (mousike), art of the Muses, whose mythological mother was Mnemosyne, memory. But it can also summon up the blood, console the bereaved, inspire fanaticism, bolster governments and dissenters alike, help us learn, and make web designers dance. And what would Christmas be without music?\n\nMusic moves us, often in ways we can\u2019t explain. By some kind of alchemy, music frees us from the elaborate nuisance and inadequacy of words. Across the world and throughout recorded history \u2013 and no doubt well before that \u2013 people have listened and made (and made out to) music.\n\n\n\t[I]t appears probable that the progenitors of man, either the males or females or both sexes, before acquiring the power of expressing their mutual love in articulate language, endeavoured to charm each other with musical notes and rhythm.\n\u2014Charles DARWIN, The Descent of Man, and Selection in Relation to Sex, 1871\n\n\nIt\u2019s so integral to humankind, we\u2019ve sent it into space as a totem for who we are. (Who knows? It might be important.) Music is essential, a universal compulsion; as Nietzsche wrote, without music life would be a mistake.\n\nMusic, design and web design\n\nThere are some obvious and notable similarities between music and visual design. Both can convey mood and evoke emotion but, even under close scrutiny, how they do that remains to a great extent mysterious. Each has formal qualities or parts that can be abstracted, analysed and discussed, often using the same terminology: composition, harmony, rhythm, repetition, form, theme; even colour, texture and tone.\n\nA possible reason for these shared aspects is that both visual design and music are means to connect with people in deep and lasting ways. Furthermore, I believe the connections to be made can complement direct emotional appeal. Certain aesthetic qualities in music work on an unconscious and, it could be argued, universal level. Using musical principles in our designs, then, can help provide the connectedness between content, device and user that we now seek as web designers.\n\nYet, when we talk about music and web design, the conversation is almost always about the music designers listen to while working, a theme finding its apotheosis in Designers.MX. Sometimes, articles in that dreary list format seek inspiration from music industry websites. There\u2019s even a service offering pre-templated web designs for bands, and at least one book surveyed the landscape back in 2006. Occasionally, discussions broaden somewhat into whether and how different kinds of music can inspire and influence the design work we produce.\n\nSuch enquiries, it seems to me, are beside the point. Do I really design differently when I listen to Bach rather than Bacharach? Will the barely restrained energy of Count Basie\u2019s The Kid from Red Bank mean I choose a lively colour palette, and rural, autumnal shades when inspired by Fleet Foxes? Mahler means a thirteen-column layout? Gillian Welch leads to distressed black and white photography? While reflecting the importance we place in music and how it seems to help us in our work, surveys on musical taste and lists of favourite artists fail to recognize that some of the fundamental aesthetic characteristics of music can be adapted and incorporated into modern web design.\n\nAntiphonal geometry\n\nOver recent years, web designers have embraced grid systems as powerful tools to help create good-looking and intuitive user experiences. With the advent of responsive design, these grids and their contents must adapt to the different screen sizes and properties of all kinds of user devices. Finding and using grid values that can scale well and retain or enhance their proportions and relationships while making the user experience meaningful in several different contexts is more important than ever.\n\nIn print, this challenge has always started with the dimensions and proportions of the page. Content can thereby be made to belong inside the page and be bound to it. And music has been used for centuries to further this aim. As Robert Bringhurst says in The Elements of Typographical Style:\n\n\n\tIndeed, one of the simplest of all systems of page proportions is based on the familiar intervals of the diatonic scale. Pages that embody these basic musical proportions have been in common use in Europe for more than a thousand years.\n\n\nVery well. But while he goes on to list (from the full chromatic scale, rather than just diatonic) the proportions and the musical intervals they\u2019re based on, Bringhurst fails to mention what they\u2019re ratios of or their potential effects. Shame. In his favour, however, he later touches on how proportions in print might be considered to work:\n\n\n\tThe page is a piece of paper. It is also a visible and tangible proportion, silently sounding the thoroughbass of the book. On it lies the textblock, which must answer to the page. The two together \u2013 page and textblock \u2013 produce an antiphonal geometry. That geometry alone can bond the reader to the book. Or conversely, it can put the reader to sleep, or put the reader\u2019s nerves on edge, or drive the reader away.\n\n\nSo what does Bringhurst mean by antiphonal geometry, a phrase that marries the musical to the spatial? By stating that the textblock \u201cmust answer to the page\u201d, the implication is that the relationship between the proportions of the page and the shape of the textblock printed on it embodies a spatial (geometrical) call-and-response (antiphony) that can be appealing or not.\n\nBoulton\u2019s new canon\n\nBut, as Mark Boulton has pointed out, on the web \u201cthere are no edges. There are no \u2018pages\u2019. We\u2019ve made them up.\u201d So, what is to be done? In January 2011 at the New Adventures in Web Design conference, Boulton presented his vision of a new canon of web design, a set of principles to guide us as we design the web. There are three overlapping tenets:\n\n\n\tdesign from the content out\n\tcreate connectedness between the different content elements\n\tbind the content to the web device\n\n\nRather than design from the edges in, we need to design layout systems from the content out. To this end, Boulton asserts that grid system design should begin with a constraint, and he suggests we use the size of a fixed content element, such as an advertising unit or image, as a starting point for online grid calculations. Khoi Vinh advocates the same approach in his book, Ordering Disorder: Grid Principles for Web Design.\n\nBoulton\u2019s second and third tenets, however, are more complex and overlap significantly with each other. Connecting the different parts of the content and binding the content to the device share many characteristics and solutions:\n\n\n\tadopting ems and percentages as units of size for layout elements\n\taltering text size, line length and line height for different viewport dimensions\n\tproviding higher resolution images for devices with greater pixel densities\n\tfluid layout grids, flexible images and responsive design\n\n\nAll can help relate the presentation of the content to its delivery in a certain context.\n\nBut how do we determine the relationship between one element of a layout and another? How can we avoid making arbitrary decisions about the relative sizes of parts of our designs? What can we use to connect the parts of our design to one another, and how can we bind the presentation of the content to the user\u2019s device?\n\nTim Brown\u2019s application of modular typographic scales hints at an answer. In the very useful tool he created for calculating such scales, Brown includes two musical ratios: the perfect fifth (2:3); and the perfect fourth (3:4). Why? Where do they come from? And what do they mean?\n\nHarmonies musical and visual\n\nFundamental to music are rhythm and harmony.\n\nAs any drummer will tell you, without rhythm there is no music. Even when there\u2019s no regular beat, any tune follows a rhythm, however irregular, simply because a change of note is a point of change in the music. Although rhythm, timing and pacing are all relevant to interaction design, right now it\u2019s harmony we\u2019re interested in.\n\nSometimes harmony is called the vertical aspect of music, and melody the horizontal. But this conceit overlooks the fact that harmony is both vertical and horizontal. A single melodic line, as it is played, implies various sets of harmonies on which it is grounded, whether or not those harmonies are played. So, harmony doesn\u2019t just sit vertically beneath the horizontal melody, but moves horizontally as well, through harmonic progression.\n\nTo stretch this arrangement pixel-thin, we could argue that in onscreen design melody is the content, and the layout and arrangement of the content is the harmony. We sometimes say a design is harmonious when the interplay of different elements of a design is pleasing or balanced or in proportion, and the content (the melody) is set off or conveyed well by or appropriate to the design.\n\nWe seem to know instinctively whether a layout is harmonious\u2026\n\nIn the design of The Great Discontent, the relationships between different elements combine to form a balanced whole.\n\n\u2026or not.\n\nThere\u2019s no harmony in the Department for Education\u2019s website because the different parts of the content don\u2019t feel related to one another.\n\nWhat is it that makes one design harmonious and another dissonant? It\u2019s not just whether things line up, though that\u2019s a start. I believe there are much deeper aesthetic forces at work, forces we can tap into in our onscreen designs. Now, I\u2019m not going start a difficult discussion about aesthetics. For our purposes, we just need to know that it\u2019s the branch of philosophy dealing with the nature of beauty, and the creation and perception of beauty. And among the key components in the perception of beauty are harmony and proportion. These have been part of traditional western aesthetics since Plato (about 2,500 years).\n\nOne of the ways we appreciate the beauty of music is through the harmonic intervals we hear. A musical interval is a combination of two notes and it describes the distance between the two pitches. For example, the distance between C and the G above it (if we take C as the tonic or root) is called a perfect fifth.\n\nLeft: C to G, a perfect fifth. Right: C and G, not a perfect fifth.\n\n \n\nAnd, to get superficially scientific for a moment, each musical interval can be expressed as a ratio of the wavelength frequencies of the notes; for our perfect fifth, with every two wavelengths of C, there are three of G. And what is a ratio, if not a proportion of one thing to another?\n\nSo, simple musical harmony (using what\u2019s known as just intonation1) affords us a set of proportions, expressed as ratios. Where better to apply these ideas of harmony and proportion from music in web design, than grid systems?\n\nA digression: whither \u03c6?\n\nQuite often in our discussions of pure design and aesthetics, we mention the golden ratio and regurgitate the same justifications for its use: roots in antiquity; embodied in classical and Renaissance architecture and art; occurrence in nature; the New Twitter, and so forth (oh, really?).\n\nYet the ratios of musical intervals from just intonation are equally venerable and much more widespread: described by Pythagorus; employed in Palladian architecture, and printing, books and art from the Renaissance onwards; in modern times, film and television dimensions; standard international paper sizes (ISO 216, the A and B series); and, again and again, screen dimensions \u2013 chances are that screen you\u2019re probably looking at right now has the proportions 2:3 (iPhone and iPod Touch), 3:4 (iPad and Kindle), 3:5 (many smartphones), 5:8 or 16:9 (many widescreen monitors), all ratios of musical intervals.\n\nBack to our theme\u2026\n\nMusical interval ratios\n\nLet\u2019s take a look at most of the ratios within a couple of octaves and crunch some numbers to generate some percentages and other values that we can use in our designs. First, the intervals and their ratios in just intonation and expressed as ratios of one:\n\n\n\t\t\n\t\t\tName \n\t\t\tInterval in C \n\t\t\tRatio \n\t\t\tRatio (1:x) \n\t\t\n\t\t\n\t\t\t unison \n\t\t\t C\u2192C \n\t\t\t 1:1 \n\t\t\t 1:1 \n\t\t\n\t\t\n\t\t\t minor second \n\t\t\t C\u2192D\u266d \n\t\t\t 15:16 \n\t\t\t 1:1.067 \n\t\t\n\t\t\n\t\t\t major second \n\t\t\t C\u2192D \n\t\t\t 8:9 \n\t\t\t 1:1.125 \n\t\t\n\t\t\n\t\t\t minor third \n\t\t\t C\u2192E\u266d \n\t\t\t 5:6 \n\t\t\t 1:1.2 \n\t\t\n\t\t\n\t\t\t major third \n\t\t\t C\u2192E \n\t\t\t 4:5 \n\t\t\t 1:1.25 \n\t\t\n\t\t\n\t\t\t perfect fourth \n\t\t\t C\u2192F \n\t\t\t 3:4 \n\t\t\t 1:1.333 \n\t\t\n\t\t\n\t\t\t augmented fourth \nor diminished fifth \n\t\t\t C\u2192F\u266f/G\u266d \n\t\t\t 1:\u221a2 \n\t\t\t 1:1.414 \n\t\t\n\t\t\n\t\t\t perfect fifth \n\t\t\t C\u2192G \n\t\t\t 2:3 \n\t\t\t 1:1.5 \n\t\t\n\t\t\n\t\t\t minor sixth \n\t\t\t C\u2192A\u266d \n\t\t\t 5:8 \n\t\t\t 1:1.6 \n\t\t\n\t\t\n\t\t\t major sixth \n\t\t\t C\u2192A \n\t\t\t 3:5 \n\t\t\t 1:1.667 \n\t\t\n\t\t\n\t\t\t minor seventh \n\t\t\t C\u2192B\u266d \n\t\t\t 9:16 \n\t\t\t 1:1.778 \n\t\t\n\t\t\n\t\t\t major seventh \n\t\t\t C\u2192B \n\t\t\t 8:15 \n\t\t\t 1:1.875 \n\t\t\n\t\t\n\t\t\t octave \n\t\t\t C\u2192C\u2191 \n\t\t\t 1:2 \n\t\t\t 1:2 \n\t\t\n\t\t\n\t\t\t major tenth \n\t\t\t C\u2192E\u2191 \n\t\t\t 2:5 \n\t\t\t 1:2.5 \n\t\t\n\t\t\n\t\t\t major eleventh \n\t\t\t C\u2192F\u2191 \n\t\t\t 3:8 \n\t\t\t 1:2.667 \n\t\t\n\t\t\n\t\t\t major twelfth \n\t\t\t C\u2192G\u2191 \n\t\t\t 1:3 \n\t\t\t 1:3 \n\t\t\n\t\t\n\t\t\t double octave \n\t\t\t C\u2192C\u2191 \n\t\t\t 1:4 \n\t\t\t 1:4 \n\t\t\n\t\t\n\t\t\tName \n\t\t\tInterval in C \n\t\t\tRatio \n\t\t\tRatio (1:x) \n\t\t\n\n\nAnd now as percentages, of both the larger and smaller values in the ratios:\n\n\n\t\t\n\t\t\tName \n\t\t\tRatio \n\t\t\t% of larger value \n\t\t\t% of smaller value \n\t\t\n\t\t\n\t\t\t unison \n\t\t\t 1:1 \n\t\t\t 100% \n\t\t\t 100% \n\t\t\n\t\t\n\t\t\t minor second \n\t\t\t 15:16 \n\t\t\t 93.75% \n\t\t\t 106.667% \n\t\t\n\t\t\n\t\t\t major second \n\t\t\t 8:9 \n\t\t\t 88.889% \n\t\t\t 112.5% \n\t\t\n\t\t\n\t\t\t minor third \n\t\t\t 5:6 \n\t\t\t 83.333% \n\t\t\t 120% \n\t\t\n\t\t\n\t\t\t major third \n\t\t\t 4:5 \n\t\t\t 80% \n\t\t\t 125% \n\t\t\n\t\t\n\t\t\t perfect fourth \n\t\t\t 3:4 \n\t\t\t 75% \n\t\t\t 133.333% \n\t\t\n\t\t\n\t\t\t augmented fourth \nor diminished fifth \n\t\t\t 1:\u221a2 \n\t\t\t 70.711% \n\t\t\t 141.421% \n\t\t\n\t\t\n\t\t\t perfect fifth \n\t\t\t 2:3 \n\t\t\t 66.667% \n\t\t\t 150% \n\t\t\n\t\t\n\t\t\t minor sixth \n\t\t\t 5:8 \n\t\t\t 62.5% \n\t\t\t 160% \n\t\t\n\t\t\n\t\t\t major sixth \n\t\t\t 3:5 \n\t\t\t 60% \n\t\t\t 166.667% \n\t\t\n\t\t\n\t\t\t minor seventh \n\t\t\t 9:16 \n\t\t\t 56.25% \n\t\t\t 177.778% \n\t\t\n\t\t\n\t\t\t major seventh \n\t\t\t 8:15 \n\t\t\t 53.333% \n\t\t\t 187.5% \n\t\t\n\t\t\n\t\t\t octave \n\t\t\t 1:2 \n\t\t\t 50% \n\t\t\t 200% \n\t\t\n\t\t\n\t\t\t major tenth \n\t\t\t 2:5 \n\t\t\t 40% \n\t\t\t 250% \n\t\t\n\t\t\n\t\t\t major eleventh \n\t\t\t 3:8 \n\t\t\t 37.5% \n\t\t\t 266.667% \n\t\t\n\t\t\n\t\t\t major twelfth \n\t\t\t 1:3 \n\t\t\t 33.333% \n\t\t\t 300% \n\t\t\n\t\t\n\t\t\t double octave \n\t\t\t 1:4 \n\t\t\t 25% \n\t\t\t 400% \n\t\t\n\t\t\n\t\t\tName \n\t\t\tRatio \n\t\t\t% of larger value \n\t\t\t% of smaller value \n\t\t\n\n\nAs you can see, the simple musical intervals are expressed as ratios of small whole numbers (integers). We can then normalize them as ratios of one, as well as derive percentage values, both in terms of the smaller value to the larger, and vice versa. These are the numbers we can incorporate into our designs. If you\u2019ve ever written something like body { font: 100%/1.5 \"Museo Sans\", Helvetica, sans-serif; } in your CSS, you\u2019re already using a musical ratio: the perfect fifth.\n\nModular scales allow us to generate a set of numbers based on a musical interval that can be used for all kinds of typographic and layout decisions to create harmony in a visual design for the web. As Tim Brown said at the 2010 Build conference:\n\n\n\tI think that from that most atomic unit \u2013 type \u2013 whole experiences can resonate, whole experiences can be harmonious. And whole experiences can have a purpose suited to our design intentions.\n\n\nOnce more, with feeling: connectedness\n\nAs well as modular scales, there are other methods of incorporating musical interval ratios into our work. Setting the ratio of font size to line height in CSS is one such example. We could also create a typographic hierarchy using the same principle and combining several ratios that we know harmonize well musically in a chord:\n\nbody { font-size: 75%; } /* =12px = base size or tonic */\n\nh1 { font-size: 32px; font-size: 2.667rem; }\n   /* =32px = 3:8 = major eleventh (C\u2192F\u2191) */\n\nh2 { font-size: 24px; font-size: 2rem; }\n   /* =24px = 1:2 = octave (C\u2192C\u2191) */\n\nh3 { font-size: 20px; font-size: 1.667rem; }\n   /* =20px = 3:5 = major sixth (C\u2192A) */\n\nfigcaption, small { font-size: 9px; font-size : 0.75rem }\n   /* =9px = 3:4 = perfect fourth (C\u2192F) */\n\nWhoa! Hold your reindeer, Santa! How can we know what interval combinations work well together to form chords? Well, I\u2019m a classically trained musician, so perhaps I have an advantage. To avoid a long, technically complex digression into musical harmony, here are a few basic combinations of intervals that are harmonious in one way or another:\n\n\n\tunison; major third; perfect fifth; octave\n\tunison; perfect fourth; major sixth; octave\n\tunison; minor third; minor sixth; octave\n\tunison; minor third; diminished fifth; major sixth; octave\n\n\nThis isn\u2019t to say that other combinations can\u2019t be used to interesting effect and particular purpose \u2013 they surely can \u2013 but I have to make sure there\u2019s something left for you to experiment with in the wee small hours over the holiday. Bear in mind, though, were I to play you two notes from the same scale to form a minor second, for example, you\u2019d probably say it was dissonant and maybe that quality of the 15:16 ratio would be translated to the design.\n\n \n\nIn the typographic hierarchy above, you\u2019ll notice I used an interval in the higher octave, which affords a broader range of ratios while retaining the harmony. Thus, a perfect fifth (2:3) becomes a major twelfth (1:3), or a major sixth (3:5) becomes a major thirteenth (3:10).\n\nThe harmonic ratios can obviously be used as proportions for layout as well, in several different ways:\n\n\n\timage width and height (for example, 450\u00d7800px = 9:16 = minor seventh)\n\tmain content to page width (67%:100% = 2:3 = perfect fifth)\n\tpage width to viewport width (80%:100% = 4:5 = major third)\n\n\nOne great benefit of using such ratios in web design work is that they can be applied in responsive web design. Proportional values, based on percentages or equivalent em units, will scale with changing viewports, so your layout and image proportions can be maintained or deliberately changed, as we\u2019re about to find out, across devices.\n\nSmall speakers, tall speakers: binding to the device\n\nThe musical interval ratios also provide an opportunity, not only to create connectedness between the parts of a layout, but to bind the content to a device \u2013 that elusive antiphonal geometry. Just as a textblock and page resonate together, so too can web content and the screen. Earlier, I mentioned that several common screen aspect ratios match musical interval ratios. It would seem, then, that we have a set of proportions that we can use in different ways to establish and retain a sense of harmony that can be based on and change with those contexts. Using musical interval ratios, we can bind the display of our content to the device it\u2019s displayed on.\n\nIf you haven\u2019t met already, let me introduce you to the device-aspect-ratio property of CSS media queries.\n\n@media only screen and (device-aspect-ratio: 3/4) { }\n@media only screen and (device-aspect-ratio: 480/640) { }\n@media only screen and (device-aspect-ratio: 600/800) { }\n@media only screen and (device-aspect-ratio: 768/1024) { }\n\nRegardless of the precise pixel values, each of these media queries would apply to devices whose display area has an aspect ratio of 3:4. It works by comparing the device-width with the device-height. (It\u2019s not to be confused with aspect-ratio, which is defined by the width and height of the browser within the device.) The values in the media query are always presented as width/height, with portrait being the default orientation for smartphones and tablets; that is, to match an iPhone screen, you\u2019d use device-aspect-ratio: 2/3, not 3/2, which won\u2019t work.\n\nHere\u2019s a table of the musical intervals with their corresponding screens.\n\n\n\t\t\n\t\t\tName \n\t\t\tdevice-aspect-ratio \n\t\t\tScreens \n\t\t\tCommon resolutions (pixels) \n\t\t\n\t\t\n\t\t\t major third \n\t\t\t 5/4 \n\t\t\t TFT LCD computer screens \n\t\t\t 1,280\u00d71,024 \n\t\t\n\t\t\n\t\t\t perfect fourth \n\t\t\t 3/4 or 4/3 \n\t\t\t iPad, Kindle and other tablets, PDAs \n\t\t\t 320\u00d7240, 768\u00d71,024 \n\t\t\n\t\t\n\t\t\t perfect fifth \n\t\t\t 2/3 \n\t\t\t iPhone, iPod Touch \n\t\t\t 320\u00d7480, 640\u00d7960 \n\t\t\n\t\t\n\t\t\t minor sixth \n\t\t\t 8/5 (16/10) \n\t\t\t Many widescreens \n\t\t\t 1,152\u00d7720, 1,440\u00d7900, 1,920\u00d71,200 \n\t\t\n\t\t\n\t\t\t major sixth \n\t\t\t 3/5 \n\t\t\t Many smartphones \n\t\t\t 240\u00d7400, 480\u00d7800 \n\t\t\n\t\t\n\t\t\t minor seventh \n\t\t\t 16/9 or 9/16 \n\t\t\t Many widescreens and some smartphones \n\t\t\t 720\u00d71,280, 1,366\u00d7768, 1,920\u00d71,080, 2,560\u00d71,440 \n\t\t\n\n\n[You might argue that I\u2019m playing fast and loose with the ratios. I suppose, mathematically speaking, 9:16 is not the same as 16:9: I\u2019m no expert. But let\u2019s not throw the baby out with the bath water, particularly at Christmas.]\n\nWith this in mind, we can begin to write media queries that will influence various typographic and layout values in line with the aspect ratios of specific screens and in combination with em-based min-width queries that work from smaller, mobile screens to larger, desktop screens.\n\nHere\u2019s a very simple demo page with only some text, an image with a caption and a little basic layout: no seasonal overindulgence here.\n\nDemo: Sample page using device-aspect-ratio media queries based on musical interval ratios\n\nOur initial styles for all devices are based on the perfect fifth, with the major third and octave rounding things out into a harmonious whole, whether or not media queries are supported. For example:\n\nhtml { font-size: 100%; line-height: 1.5; }\n   /* font-size:line-height = 16:24 = 2:3 = perfect fifth */\n\nh1 { font-size: 32px; font-size: 2rem; line-height: 1.25; }\n   /* font-size:line-height = 32:40 = 4:5 = major third\n      body:h1 = 16:32 = 1:2 = octave */\n\nWhile we should really consider methods of delivering images appropriate to the screen size, let\u2019s just stick to a single image for all devices. But why don\u2019t we change its aspect ratio from 4:3 to 3:2, to fit with our harmonic scheme? It\u2019s easy enough to do with overflow:hidden on the <figure> element to hide a part of the image, and a negative margin fudge:\n\nfigure img { margin: -8.5% 0 0 0; width: 100%; max-width: 100%; }\n\nOur first break point targets devices 320 pixels wide with an aspect ratio of 2:3, namely the iPhone and iPod Touch:\n\n/* 320px = 20\u00d716 */\n@media only screen and (min-width: 20em) and (device-aspect-ratio: 2/3) { }\n\nWe\u2019re actually already there, of course, as the intervals we\u2019ve chosen resonate with this aspect ratio \u2013 the content is already bound to the device.\n\nOur next media query, then, will make some changes to match a different ratio, the major sixth (3:5), which is same as that of many smartphones:\n\n/* 480px = 30\u00d716 */\n@media only screen and (min-width: 30em) and (device-aspect-ratio: 3/5) { }\n\nA different aspect ratio might require a change in harmony. For devices with these proportions, we\u2019ll now use the perfect fourth (3:4) and the major sixth (3:5) along with the octave we already have to create a new resonating harmony. For instance, a slightly wider screen means we can increase the  line-height to aid the legibility of longer lines:\n\nhtml { line-height: 1.667; }\n   /* font-size:line-height = 16:26.672 = 3:5 = major sixth */\n\nh1 { font-size: 32px; font-size: 2rem; line-height: 1.667; }\n   /* font-size:line-height = 32:53.333 = 3:5 = major sixth\n      body:h1 = 16:32 = 1:2 = octave */\n\nand we can remove the negative margin to display our 4:3 image in its entirety.\n\nEach screen displays content styled using relationships related to its own proportions. On the left, an iPhone 4 (2:3); on the right, a Samsung Nexus S (3:5). Your mileage may vary.\n\nAnother device, another media query. At 768 pixels, screens are wide enough to add columns. The ratios we\u2019ve used for the 3:5 screens include the perfect fourth (3:4) so we don\u2019t need to change any of the font measurements, but we can base the proportions of the columns on the major sixth interval:\n\narticle { float: left; width: 56%; }\n   /* width of main column 3:5 (60% of 100%, major sixth)\n      incorporating gutter width */\n\naside { float : right; width : 36%; }\n\nOn devices with a 3:4 aspect ratio, this works even better in landscape orientation.\n\nWhile not every screen over 768 pixels wide will have 3:4 proportions, the range of intervals informing the design ensure harmonious relationships between the different parts of the layout.\n\nFor wide screens proper (break point at 1,280 pixels) we can employ a new set of harmonious intervals. Many laptop and desktop screens have a 16:10 aspect ratio, which boils down to 8:5, equivalent to the minor sixth (5:8). Combined with a minor third (5:6) and the octave (1:2), this creates a new harmony appropriate to these devices. Let\u2019s increase the font size and change the image\u2019s aspect ratio to match:\n\nhtml { font-size: 120%; line-height: 1.6; }\n   /* font-size increased for wider screens from 16px to 19.2px\n      (5:6 = minor third)\n      font-size:line-height = 19.2:30.72 = 5:8 = minor sixth */\n\nfigure img { margin: -12.5% 0 0 ; }\t\n   /* using -ve margin combined with overflow:hidden\n      on the figure element\n      to crop the image from 4:3 to 8:5 = minor sixth */\n\nA wide screen with a 8:5 (16:10) aspect ratio and an image to match.\n\nWith more pixels at our disposal, we can also now use the musical interval ratios to determine the width of the layout, and change the column proportions as well:\n\nsection { margin: 0 auto; width: 83.333%; }\n   /* content width:screen width = 5:6 = minor third */\n\narticle { width: 60%; }\n   /* width of main column 5:8 (62.5% of 100%, minor sixth)\n      incorporating gutter width */\n\naside { width: 35%; }\n\nWith some carefully targeted media queries, we can begin to reach towards fulfilling the second and third tenets of Boulton\u2019s new canon for web design: connecting the parts of content through relationships embodied in the layout design; and binding the content to the devices people use to access it.\n\nCoda\n\nMusical interval ratios and screen aspect ratios reveal more than convenient correspondence. These proportions work on a deep aesthetic level. Much is claimed for the golden ratio \u03c6, but none of the screens pervading our lives use it. Perhaps that\u2019s an accident of technology, but can making screens to \u03c6\u2019s proportions be more difficult or expensive than 2:3 or 3:4 or 16:10? Here, then, is not just one but a set of proportions with a uniquely human focus, originating in nature, recognized in antiquity, fundamental still.\n\nWe find music to be an art steeped with meaning, yet, unlike literary and representational arts, purely instrumental music has no obvious semantic content. It boasts an ability to express emotions while remaining an abstract art in some sense, which makes it very like design. These days, we\u2019re rightly encouraged to design for emotion, to make our users\u2019 experience meaningful, seductive, delightful. Using musical ideas and principles in our designs can help achieve those ends.\n\nLet\u2019s not be na\u00efve, of course; designing web pages is even less like composing music than it\u2019s like designing for print. In visual design, the eye will always be sovereign to the ear; following these principles will only get us so far. We cannot truly claim that a carefully composed web page layout will have the same qualities and effect as any musical patterns that inform it. In music, a set of intervals is always harmonious in relation to other sets of intervals: music rarely stands still. What aspect ratios will future screens take? Already today there is great variation in devices and support for media queries (and within that, support for device-aspect-ratio). And what of non-western musical traditions? Or rhythm, form, tempo and dynamics? What I\u2019ve demonstrated above is only a suggestion, a tentative exploration of one possible way forward.\n\nBut as our discipline matures and we become more articulate about what we do, we must look longer and deeper into areas of human endeavour already rich with value. Music is a fertile ground to explore and has the potential to yield up new approaches for web design.\n\nFootnotes\n\n \n Just intonation is a system of tuning that uses small integers to describe the musical intervals, based initially on the perfect fifth, that most consonant of intervals.

What is clear is that our light-on-dark text is now of a comparable weight to its dark-on-light counterpart.\n\n \n\nYou can see this trick in effect all over ShaunInman.com and in the navigation on haveamint.com and Subtraction.com.

{"rowid": 84, "title": "Responsive Responsive Design", "contents": "Now more than ever, we\u2019re designing work meant to be viewed along a gradient of different experiences. Responsive web design offers us a way forward, finally allowing us to \u201cdesign for the ebb and flow of things.\u201d\n\n\nWith 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.\n\nCertainly, 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\u2019s unique ability to be consumed and interacted with on any number of devices, with any number of input methods is something to be embraced.\n\nBut there\u2019s one part of the web\u2019s 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.\n\nA few months back, Stephanie Rieger tweeted\n\n\n\t\u201cShoot me now\u2026responsive design has seemingly become confused with an opportunity to reduce performance rather than improve it.\u201d\n\n\nI 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:\n\n\n\t74 requests, 1,511kb\n\t114 requests, 1,200kb\n\t99 requests, 1,298kb\n\t105 requests, 5,942kb\n\n\nAnd those numbers were for the small screen versions of each site!\n\nThese sites were praised for their visual design and responsive nature, and rightfully so. They\u2019re 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.\n\nIt would be one thing if these were the exceptions, but unfortunately they\u2019re 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.\n\nThe 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.\n\nThe bottom line: performance is a fundamental component of the user experience.\n\nSo, given it\u2019s extreme importance in the success of any web project, why is it that we\u2019re seeing so many bloated responsive sites?\n\nFirst, I adamantly disagree with the belief that poor performance is inherent to responsive design. That\u2019s not a rule \u2013 it\u2019s a cop-out. It\u2019s 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\u2019s hardly an issue resigned to one technique.\n\nTo 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.\n\nCreate a culture of performance\n\nIf 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. \n\nOne 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\u2019t let a page go live if either of those numbers is exceeded. The BBC does this with its responsive mobile site.\n\nA 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:\n\n\n\tOptimize an existing feature or asset on the page\n\tRemove an existing feature or asset from the page\n\tDon\u2019t add the new feature or asset\n\n\nThe 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.\n\nEmbrace the pain\n\nThis 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\u2019t feel so bad. \n\nWhen 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\u2019t have launched in that state.\n\nDon\u2019t just crunch numbers. Fire up your site on a slower network and see what it feels like to wait. If you don\u2019t 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.\n\nWatch for low-hanging fruit\n\nThere are a bunch of general performance improvements that apply to any site (responsive or not) but often aren\u2019t made. A great starting point is to refer to Yahoo!\u2018s list of rules.\n\nSome of this might sound complicated or intimidating, but it doesn\u2019t have to be. You can grab an .htaccess file from HTML 5 Boilerplate or use Sergey Chernyshev\u2019s drop-in .htaccess file. You can use tools like SpriteMe to simplify the creation of sprites, and ImageOptim to compress images.\n\nJust by implementing these simple optimizations you will achieve a noticeable improvement in terms of weight and page load time.\n\nBe careful with images\n\nThe most common offender for poor responsive performance is downloading unnecessarily large images, or worse yet, multiple sizes of the same image. \n\nFor background images, simply being careful with where and how you include the image can ensure you don\u2019t get caught in the trap of multiple background images being downloaded without being used. Don\u2019t count on display:none to help. While it may hide elements from displaying on screen, those images will still be requested and downloaded.\n\nContent images can be a little trickier. Whatever you do, don\u2019t serve a large image that works on a large screen display to small screens. It\u2019s 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. \n\nThe new <picture> element that has been so often discussed is another excellent solution if you\u2019re feeling particularly future-oriented. A picture polyfill exists so that you can start using the element now without any worries about support.\n\nConditional loading\n\nDon\u2019t load any more than you absolutely need to. If a script isn\u2019t 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.\n\nLast 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\u2019s a powerful and simple way to lighten the load on small screens as well as reduce clutter.\n\nGo vanilla?\n\nIf you take a look at the HTTP Archive you\u2019ll 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. \n\nMuch of the weight can be attributed to our industry\u2019s increasing reliance on frameworks. This is especially a concern on mobile devices. PPK recently exclaimed that current JavaScript libraries are just \u201ctoo heavy for mobile\u201d. \u201cResearch 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.\n\nThere\u2019s nothing wrong about using a framework, but the problem is that they\u2019ve 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.)\n\nStart thinking beyond visual aesthetics\n\nWe love to tout the web\u2019s 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.\n\nThe web is an incredibly dynamic and interactive medium, and designing for it demands that we consider more than just visual aesthetics. Let\u2019s not forget to give those other qualities the attention they deserve.", "year": "2012", "author": "Tim Kadlec", "author_slug": "timkadlec", "published": "2012-12-05T00:00:00+00:00", "url": "https://24ways.org/2012/responsive-responsive-design/", "topic": "design"}
{"rowid": 25, "title": "The Introvert Owner\u2019s Manual", "contents": "Nobody realizes that some people expend tremendous energy merely to be normal.\nAlbert Camus\n\n\n\u201cWhatever you plan, just make sure there are lots of people there,\u201d said my husband in the run-up to his birthday last year. A few months later, before my own birthday, I uttered, \u201cWhatever you plan, just make sure it is only me and you.\u201d\n\nI am an introvert. It is very likely some of you are too, or that you live, work or fraternise with one. Despite there being quite a few of us out there \u2013 some say as many as one third of the population, others as little as ten per cent \u2013 I think our professional and social lives are biased towards a definition of normality that is more accepting of the extrovert. I hope that by reading this article you will gain some insight to what goes on inside the head of the introvert(s) that you know and understand how to relate to them in a way that respects their disposition.\n\nBefore we go any further, I should define what exactly being an introvert means, and, equally important, what it does not. Only once this is established will you be able to handle your introvert correctly.\n\nWhat defines an introvert\n\nThe simplest and most accurate way of describing an introvert is that she uses up energy in social situations and needs to be in solitude to recharge.\n\nTo explain what I mean, let us take the example of the The Sims: when you create a Sim, you can choose (among other characteristics) whether it will be outgoing or not. If the Sim is outgoing, when you play the game you need to make sure it interacts as much as possible with other Sims or its mood indicator (the plumbob) will become red and that is a bad thing. Conversely, if your Sim is not outgoing, when you put it in too many social situations its plumbob will become red too.\n\nSo your (real life) introvert might think you are great (you might even be her best friend, her spouse or her child), but if her plumbob is red, or nearly, she might just need a little time and space to recharge before she is ready to interact.\n\nThis is not the same thing as being shy or in a bad mood all the time. We are not necessarily awkward in social situations, but, if we have not had the time to recharge, being social might be almost impossible. This explains why your introvert will likely ask who will be at the gathering you have planned, for how long she will have to stay there, and what she will be doing before and after the event. It is the equivalent of you wanting to know if there will be power sockets in the restaurant to charge your iPhone \u2013 asking this does not mean you don\u2019t want to attend.\n\nThe explanation above might be a simplistic way of looking at things, but I would say it is one that introverts can relate to; call it a minimalist approach to socialisation.\n\nCaring for your introvert\n\nArticles and conversations about introversion usually focus on how to fix the condition and how to make introverts more outgoing: a clear example of our society\u2019s bias towards the normality of extroversion. Avoid this. You will not be able to convert your introvert into an extrovert. Believe it or not, there is nothing wrong with her.\n\nIn her 2012 TED talk, \u201cThe power of introverts\u201d, Susan Cain pointed to the fact that places like school and work are designed for extroverts: students and workers are required to constantly work in groups and speaking up is highly valued. Both types are evaluated against the same criteria and more often than not people are expected to excel at being outspoken to be considered well rounded.\n\nObviously, this is not the right way to appraise your introvert. Comparing your introvert with an extrovert using the same parameters and simply asking her to behave more like an extrovert is a mistake and something that will only perpetuate an introvert\u2019s idea that the problem lies with her.\n\nSpeaking up\n\nYour introvert is likely to have strong opinions and ideas, and to have been listening to other people speak at meetings and workshops. Help her voice those thoughts by creating an environment where everyone stops and listens when someone speaks instead of one which fosters interruptions. Show her that it is acceptable for someone to take time to think before they speak: silences are OK. Allow her the freedom to be herself instead of pressuring her to change an innate quality.\n\nIt is not uncommon to find an introvert who likes to express ideas in writing. The world of web professionals excels in the spread of knowledge that is shared and sought through the written word. Give your introvert the necessary time and tools to write about the job, if she is that way inclined; this might be a good alternative to asking her to speak out.\n\nGroup work\n\nI remember the sinking feeling whenever I heard my teachers say the dreaded words: \u201cAnd now you\u2019re going to break out into groups of\u2026\u201d Being an introvert does not mean you do not like people (or like to be around or work with others). It is just that activities such as group work will invariably drain your introvert\u2019s energy rapidly. Your introvert\u2019s batteries will need to be fully charged for her to be at her best and afterwards she will most likely need to recharge.\n\nQuiet time\n\nThese days, one of the things that I value most at work is the ability to have moments to create and to think in solitude. When I am able to have those moments at the right time I will in turn be happy to participate in group conversations and tasks. Allow your introvert to have those moments: this does not mean she will have to work from home one day a week (but maybe it will); it might simply mean allowing her to take her laptop and her notebook and work from the empty side of the office, or from the coffee shop downstairs for an hour or two. In all likelihood she will come back fully recharged and ready to engage in more social activities \u2013 her plumbob will again be bright green.\n\nLeadership\n\nDo not think that your introvert cannot lead. Cain notes that introverted leaders are more likely to let their proactive employees run with their ideas instead of taking the ideas as their own. I would say that is a positive attribute in a leader. Maybe next time a project starts, talk to your introvert about the possibility of her being in a leadership position or of having more responsibility: you might be surprised at her ability to plan and foresee potential obstacles in the project.\n\nFinal thoughts\n\nYou would not tell someone with dyslexia to get better at spelling without giving her the right tools and enough time to do so. Equally, do not ask your introvert to be more outgoing, or to turn her frown upside down, without giving her the space to do so.\n\nI believe that everyone is an introvert at some point. Everyone needs a moment of solitude now and then, and the work we do requires frequent periods of deep focus and concentration. Striving to create workplaces, classrooms, homes that allow introverts to shine and be comfortable in their skin has the potential to also make those places more balanced for everyone else.\n\nResources and further reading\n\n\n\tThe power of introverts\n\t10 myths about introverts\n\tSusan Cain\u2019s 2014 TED Talk | Announcing the Quiet Revolution\n\tHelp Shy Kids \u2014 Don\u2019t Punish Them\n\tThe Introvert Advantage\n\t6 Things You Thought Wrong About Introverts\n\tExtraversion and introversion", "year": "2014", "author": "Inayaili de Le\u00f3n Persson", "author_slug": "inayailideleon", "published": "2014-12-13T00:00:00+00:00", "url": "https://24ways.org/2014/the-introvert-owners-manual/", "topic": "process"}
{"rowid": 165, "title": "Transparent PNGs in Internet Explorer 6", "contents": "Newer breeds of browser such as Firefox and Safari have offered support for PNG images with full alpha channel transparency for a few years. With the use of hacks, support has been available in Internet Explorer 5.5 and 6, but the hacks are non-ideal and have been tricky to use. With IE7 winning masses of users from earlier versions over the last year, full PNG alpha-channel transparency is becoming more of a reality for day-to-day use.\n\nHowever, there are still numbers of IE6 users out there who we can\u2019t leave out in the cold this Christmas, so in this article I\u2019m going to look what we can do to support IE6 users whilst taking full advantage of transparency for the majority of a site\u2019s visitors.\n\nSo what\u2019s alpha channel transparency?\n\nCast your minds back to the Ghost of Christmas Past, the humble GIF. Images in GIF format offer transparency, but that transparency is either on or off for any given pixel. Each pixel\u2019s either fully transparent, or a solid colour. In GIF, transparency is effectively just a special colour you can chose for a pixel.\n\nThe PNG format tackles the problem rather differently. As well as having any colour you chose, each pixel also carries a separate channel of information detailing how transparent it is. This alpha channel enables a pixel to be fully transparent, fully opaque, or critically, any step in between.\n\nThis enables designers to produce images that can have, for example, soft edges without any of the \u2018halo effect\u2019 traditionally associated with GIF transparency. If you\u2019ve ever worked on a site that has different colour schemes and therefore requires multiple versions of each graphic against a different colour, you\u2019ll immediately see the benefit. \n\nWhat\u2019s perhaps more interesting than that, however, is the extra creative freedom this gives designers in creating beautiful sites that can remain web-like in their ability to adjust, scale and reflow.\n\nThe Internet Explorer problem\n\nUp until IE7, there has been no fully native support for PNG alpha channel transparency in Internet Explorer. However, since IE5.5 there has been some support in the form of proprietary filter called the AlphaImageLoader. Internet Explorer filters can be applied directly in your CSS (for both inline and background images), or by setting the same CSS property with JavaScript. \n\nCSS:\n\nimg {\n\tfilter: progid:DXImageTransform.Microsoft.AlphaImageLoader(...);\n}\n\nJavaScript:\n\nimg.style.filter = \"progid:DXImageTransform.Microsoft.AlphaImageLoader(...)\";\n\nThat may sound like a problem solved, but all is not as it may appear. Firstly, as you may realise, there\u2019s no CSS property called filter in the W3C CSS spec. It\u2019s a proprietary extension added by Microsoft that could potentially cause other browsers to reject your entire CSS rule. \n\nSecondly, AlphaImageLoader does not magically add full PNG transparency support so that a PNG in the page will just start working. Instead, when applied to an element in the page, it draws a new rendering surface in the same space that element occupies and loads a PNG into it. If that sounds weird, it\u2019s because that\u2019s precisely what it is. However, by and large the result is that PNGs with an alpha channel can be accommodated.\n\nThe pitfalls\n\nSo, whilst support for PNG transparency in IE5.5 and 6 is possible, it\u2019s not without its problems.\n\nBackground images cannot be positioned or repeated\n\nThe AlphaImageLoader does work for background images, but only for the simplest of cases. If your design requires the image to be tiled (background-repeat) or positioned (background-position) you\u2019re out of luck. The AlphaImageLoader allows you to set a sizingMethod to either crop the image (if necessary) or to scale it to fit. Not massively useful, but something at least.\n\nDelayed loading and resource use\n\nThe AlphaImageLoader can be quite slow to load, and appears to consume more resources than a standard image when applied. Typically, you\u2019d need to add thousands of GIFs or JPEGs to a page before you saw any noticeable impact on the browser, but with the AlphaImageLoader filter applied Internet Explorer can become sluggish after just a handful of alpha channel PNGs.\n\nThe other noticeable effect is that as more instances of the AlphaImageLoader are applied, the longer it takes to render the PNGs with their transparency. The user sees the PNG load in its original non-supported state (with black or grey areas where transparency should be) before one by one the filter kicks in and makes them properly transparent.\n\nBoth the issue of sluggish behaviour and delayed load only really manifest themselves with volume and size of image. Use just a couple of instances and it\u2019s fine, but be careful adding more than five or six. As ever, test, test, test.\n\nLinks become unclickable, forms unfocusable \n\nThis is a big one. There\u2019s a bug/weirdness with AlphaImageLoader that sometimes prevents interaction with links and forms when a PNG background image is used. This is sometimes reported as a z-index issue, but I don\u2019t believe it is. Rather, it\u2019s an artefact of that weird way the filter gets applied to the document almost outside of the normal render process. \n\nOften this can be solved by giving the links or form elements hasLayout using position: relative; where possible. However, this doesn\u2019t always work and the non-interaction problem cannot always be solved. You may find yourself having to go back to the drawing board.\n\nSidestepping the danger zones\n\nFrankly, it\u2019s pretty bad news if you design a site, have that design signed off by your client, build it and then find out only at the end (because you don\u2019t know what might trigger a problem) that your search field can\u2019t be focused in IE6. That\u2019s an absolute nightmare, and whilst it\u2019s not likely to happen, it\u2019s possible that it might. It\u2019s happened to me. So what can you do?\n\nThe best approach I\u2019ve found to this scenario is\n\n\n\tIsolate the PNG or PNGs that are causing the problem. Step through the PNGs in your page, commenting them out one by one and retesting. Typically it\u2019ll be the nearest PNG to the problem, so try there first. Keep going until you can click your links or focus your form fields.\n\tThis is where you really need luck on your side, because you\u2019re going to have to fake it. This will depend on the design of the site, but some way or other create a replacement GIF or JPEG image that will give you an acceptable result. Then use conditional comments to serve that image to only users of IE older than version 7.\n\n\nA hack, you say? Well, you started it chum.\n\nApplying AlphaImageLoader\n\nBecause the filter property is invalid CSS, the safest pragmatic approach is to apply it selectively with JavaScript for only Internet Explorer versions 5.5 and 6. This helps ensure that by default you\u2019re serving standard CSS to browsers that support both the CSS and PNG standards correct, and then selectively patching up only the browsers that need it. \n\nSeveral years ago, Aaron Boodman wrote and released a script called sleight for doing just that. However, sleight dealt only with images in the page, and not background images applied with CSS. Building on top of Aaron\u2019s work, I hacked sleight and came up with bgsleight for applying the filter to background images instead. That was in 2003, and over the years I\u2019ve made a couple of improvements here and there to keep it ticking over and to resolve conflicts between sleight and bgsleight when used together. However, with alpha channel PNGs becoming much more widespread, it\u2019s time for a new version.\n\nIntroducing SuperSleight\n\nSuperSleight adds a number of new and useful features that have come from the day-to-day needs of working with PNGs.\n\n\n\tWorks with both inline and background images, replacing the need for both sleight and bgsleight\n\tWill automatically apply position: relative to links and form fields if they don\u2019t already have position set. (Can be disabled.)\n\tCan be run on the entire document, or just a selected part where you know the PNGs are. This is better for performance.\n\tDetects background images set to no-repeat and sets the scaleMode to crop rather than scale.\n\tCan be re-applied by any other JavaScript in the page \u2013 useful if new content has been loaded by an Ajax request.\n\n\n  Download SuperSleight \n\nImplementation\n\nGetting SuperSleight running on a page is quite straightforward, you just need to link the supplied JavaScript file (or the minified version if you prefer) into your document inside conditional comments so that it is delivered to only Internet Explorer 6 or older.\n\n<!--[if lte IE 6]>\n\t<script type=\"text/javascript\" src=\"supersleight-min.js\"></script>\n<![endif]-->\n\nSupplied with the JavaScript is a simple transparent GIF file. The script replaces the existing PNG with this before re-layering the PNG over the top using AlphaImageLoaded. You can change the name or path of the image in the top of the JavaScript file, where you\u2019ll also find the option to turn off the adding of position: relative to links and fields if you don\u2019t want that.\n\nThe script is kicked off with a call to supersleight.init() at the bottom. The scope of the script can be limited to just one part of the page by passing an ID of an element to supersleight.limitTo(). And that\u2019s all there is to it.\n\nUpdate March 2008: a version of this script as a jQuery plugin is also now available.", "year": "2007", "author": "Drew McLellan", "author_slug": "drewmclellan", "published": "2007-12-01T00:00:00+00:00", "url": "https://24ways.org/2007/supersleight-transparent-png-in-ie6/", "topic": "code"}
{"rowid": 299, "title": "What the Heck Is Inclusive Design?", "contents": "Naming things is hard. And I don\u2019t just mean CSS class names and JSON properties. Finding the right term for what we do with the time we spend awake and out of bed turns out to be really hard too.\nI\u2019ve variously gone by \u201cfront-end developer\u201d, \u201cuser experience designer\u201d, and \u201caccessibility engineer\u201d, all clumsy and incomplete terms for labeling what I do as an\u2026 erm\u2026 see, there\u2019s the problem again.\nIt\u2019s tempting to give up entirely on trying to find the right words for things, but this risks summarily dispensing with thousands of years spent trying to qualify the world around us. So here we are again.\nRecently, I\u2019ve been using the term \u201cinclusive design\u201d and calling myself an \u201cinclusive designer\u201d a lot. I\u2019m not sure where I first heard it or who came up with it, but the terminology feels like a good fit for the kind of stuff I care to do when I\u2019m not at a pub or asleep.\nThis article is about what I think \u201cinclusive design\u201d means and why I think you might like it as an idea.\nIsn\u2019t \u2018inclusive design\u2019 just \u2018accessibility\u2019 by another name?\nNo, I don\u2019t think so. But that\u2019s not to say the two concepts aren\u2019t related. Note the \u2018design\u2019 part in \u2018inclusive design\u2019 \u2014 that\u2019s not just there by accident. Inclusive design describes a design activity; a way of designing things.\nThis sets it apart from accessibility \u2014 or at least our expectations of what \u2018accessibility\u2019 entails. Despite every single accessibility expert I know (and I know a lot) recommending that accessibility should be integrated into design process, it is rarely ever done. Instead, it is relegated to an afterthought, limiting its effect.\nThe term \u2018accessibility\u2019 therefore lacks the power to connote design process. It\u2019s not that we haven\u2019t tried to salvage the term, but it\u2019s beginning to look like a lost cause. So maybe let\u2019s use a new term, because new things take new names. People get that.\nThe \u2018access\u2019 part of accessibility is also problematic. Before we get ahead of ourselves, I don\u2019t mean access is a problem \u2014 access is good, and the more accessible something is  the better. I mean it\u2019s not enough by itself.\nImagine a website filled with poorly written and lackadaisically organized information, including a bunch of convoluted and confusing functionality. To make this site accessible is to ensure no barriers prevent people from accessing the content. \nBut that doesn\u2019t make the content any better. It just means more people get to suffer it. \nWhoopdidoo.\nAccess is certainly a prerequisite of inclusion, but accessibility compliance doesn\u2019t get you all the way there. It\u2019s possible to check all the boxes but still be left with an unusable  interface. And unusable interfaces are necessarily inaccessible ones. Sure, you can take an unusable interface and make it accessibility compliant, but that only placates stakeholders\u2019 lawyers, not users. Users get little value from it.\nSo where have we got to? Access is important, but inclusion is bigger than access. Inclusive design means making something valuable, not just accessible, to as many people as we can.\nSo inclusive design is kind of accessibility + UX?\nCloser, but there are some problems with this definition.\nUX is, you will have already noted, a broad term encompassing activities ranging from conducting research studies to optimizing the perceived affordance of interface elements. But overall, what I take from UX is that it\u2019s the pursuit of making interfaces  understandable.\nAs it happens, WCAG 2.0 already contains an \u2018Understandable\u2019 principle covering provisions such as readability, predictability and feedback. So you might say accessibility \u2014 at least as described by WCAG \u2014 already covers UX.\nUnfortunately, the criteria are limited, plus some really important stuff (like readability) is relegated to the AAA level; essentially \u201cbonus points if you get the time (you won\u2019t).\u201d\nSo better to let UX folks take care of this kind of thing. It\u2019s what they do. Except, therein lies a danger. UX professionals don\u2019t tend to be well versed in accessibility, so their \u2018solutions\u2019 don\u2019t tend to work for that many people. My friend Billy Gregory coined the term SUX, or \u201cSome UX\u201d: if it doesn\u2019t work for different users, it\u2019s only doing part of the job it should be. \nSUX won\u2019t do, but it\u2019s not just a disability issue. All sorts of user circumstances go unchecked when you\u2019re shooting straight for what people like, and bypassing what people need: device type, device settings, network quality, location, native language, and available time to name just a few.\nIn short, inclusive design means designing things for people who aren\u2019t you, in your situation. In my experience, mainstream UX isn\u2019t very good at that. By bolting accessibility onto mainstream UX we labor under the misapprehension that most people have a \u2018normal\u2019 experience, a few people are exceptions, and that all of the exceptions pertain to disability directly.\nSo inclusive design isn\u2019t really about disability?\nIt is about disability, but not in the same way as accessibility. Accessibility (as it is typically understood, anyway) aims to make sure things work for people with clinically recognized disabilities. Inclusive design aims to make sure things work for people, not forgetting those with clinically recognized disabilities. A subtle, but not so subtle, difference.\nLet\u2019s go back to discussing readability, because that\u2019s a good example. Now: everyone benefits from readable text; text with concise sentences and widely-understood words. It certainly helps people with cognitive impairments, but it doesn\u2019t hinder folks who have less trouble with comprehension. In fact, they\u2019ll more than likely be thankful for the time saved and the clarity. Readable text covers the whole gamut. It\u2019s \u2014 you\u2019ve got it \u2014 inclusive.\nLegibility is another one. A clear, well-balanced typeface makes the reading experience less uncomfortable and frustrating for all concerned, including those who have various forms of visual dyslexia. Again, everyone\u2019s happy \u2014 so why even contemplate a squiggly, sketchy typeface? Leave well alone.\nContrast too. No one benefits from low contrast; everyone benefits from high contrast. Simple. There\u2019s no more work involved, it just entails better decision making. And that\u2019s what design is really: decision making.\nHow about zoom support? If you let your users pinch zoom on their phones they can compensate for poor eyesight, but they can also increase the touch area of controls, inspect detail in images, and compose better screen shots. Unobtrusively supporting options like zoom makes interfaces much more inclusive at very little cost.\nAnd when it comes to the underlying HTML code, you\u2019re in luck: it has already been designed, from the outset, to be inclusive. HTML is a toolkit for inclusion. Using the right elements for the job doesn\u2019t just mean the few who use screen readers benefit, but keyboard accessibility comes out-of-the-box, you can defer to browser behavior rather than writing additional scripts, the code is easier to read and maintain, and editors can create content that is effortlessly presentable. \nWait\u2026 are you talking about universal design?\nHmmm. Yes, I guess some folks might think of \u201cuniversal design\u201d and \u201cinclusive design\u201d as synonymous. I just really don\u2019t like the term universal in this context. \nThe thing is, it gives the impression that you should be designing for absolutely everyone in the universe. Though few would adopt a literal interpretation of \u201cuniversal\u201d in this context, there are enough developers who would deliberately misconstrue the term and decry universal design as an impossible task. I\u2019ve actually had people push back by saying, \u201cwhat, so I\u2019ve got to make it work for people who are allergic to computers? What about people in comas?\u201d\nFor everyone\u2019s sake, I think the term \u2018inclusive\u2019 is less misleading. Of course you can\u2019t make things that everybody can use \u2014 it\u2019s okay, that\u2019s not the aim. But with everything that\u2019s possible with web technologies, there\u2019s really no need to exclude people in the vast numbers that we usually are. \nAccessibility can never be perfect, but by thinking inclusively from planning, through prototyping to production, you can cast a much wider net. That means more and happier users at very little if any more effort.\nIf you like, inclusive design is the means and accessibility is the end \u2014 it\u2019s just that you get a lot more than just accessibility along the way.\nConclusion\nThat\u2019s inclusive design. Or at least, that\u2019s a definition for a thing I think is a good idea which I identify as inclusive design. I\u2019ll leave you with a few tips.\nInvolve code early\nWeb interfaces are made of code. If you\u2019re not working with code, you\u2019re not working on the interface. That\u2019s not to say there\u2019s anything wrong with sketching or paper prototyping  \u2014 in fact, I recommend paper prototyping in my book on inclusive design. Just work with code as soon as you can, and think about code even before that. Maintain a pattern library of coded solutions and omit any solutions that don\u2019t adhere to basic accessibility guidelines.\nRespect conventions\nYour content should be fresh, inventive, radical. Your interface shouldn\u2019t. Adopt accepted conventions in the appearance, placement and coding of interface elements. Users aren\u2019t there to experience interface design; they\u2019re there to use an interface. In other words: stop showing off (unless, of course, the brief is to experiment with new paradigms in interface design, for an audience of interface design researchers).\nDon\u2019t be exact\n\u201cPerfection is the enemy of good\u201d. But the pursuit of perfection isn\u2019t just to be avoided because nothing ever gets finished. Exacting design also makes things inflexible and brittle. If your design depends on elements retaining precise coordinates, they\u2019ll break easily when your users start adjusting font settings or zooming. Choose not to position elements exactly or give them fixed, \u201cmagic number\u201d dimensions. Make less decisions in the interface so your users can make more decisions for it.\nEnforce simplicity\nThe virtue of simplicity is difficult to overestimate. The simpler an interface is, the easier it is to use for all kinds of users. Simpler interfaces require less code to make too, so there\u2019s an obvious performance advantage. There are many design decisions that require user research, but keeping things simple is always the right thing to do. Not simplified or simple-seeming or simplistic, but simple. \nDo a little and do it well, for as many people as you can.", "year": "2016", "author": "Heydon Pickering", "author_slug": "heydonpickering", "published": "2016-12-07T00:00:00+00:00", "url": "https://24ways.org/2016/what-the-heck-is-inclusive-design/", "topic": "process"}
{"rowid": 10, "title": "Home Kanban for Domestic Bliss", "contents": "My wife is an architect. I\u2019m a leader of big technical teams these days, but for many years after I was a dev I was a project/program manager. Our friends and family used to watch Grand Designs and think that we would make the ideal team \u2014 she could design, I could manage the project of building or converting whatever dream home we wanted.\n\nThen we bought a house.\n\nA Victorian terrace in the north-east of England that needed, well, a fair bit of work. The big decisions were actually pretty easy: yes, we should knock through a double doorway from the dining room to the lounge; yes, we should strip out everything from the utility room and redo it; yes, we should roll back the hideous carpet in the bedrooms upstairs and see if we could restore the original wood flooring.\n\nThose could be managed like a project.\n\nWhat couldn\u2019t be was all the other stuff. Incremental improvements are harder to schedule, and in a house that\u2019s over a hundred years old you never know what you\u2019re going to find when you clear away some tiles, or pull up the carpets, or even just spring-clean the kitchen (\u201cErm, hon? The paint seems to be coming off. Actually, so does the plaster\u2026\u201d). A bit like going in to fix bugs in code or upgrade a machine \u2014 sometimes you end up quite far down the rabbit hole.\n\nAnd so, as we tried to fit in those improvements in our evenings and weekends, we found ourselves disagreeing. Arguing, even. We were both trying to do the right thing (make the house better) but since we were fitting it in where we could, we often didn\u2019t get to talk and agree in detail what was needed (exactly how to make the house better). And it\u2019s really frustrating when you stay up late doing something, just to find that your other half didn\u2019t mean that they meant this instead, and so your effort was wasted.\n\nThen I saw this tweet from my friend and colleague Jamie Arnold, who was using the same kanban board approach at home as we had instituted at the UK Government Digital Service to manage our portfolio.\n\nMrs Arnold embraces Kanban wall at home. Disagreements about work in progress and priority significantly reduced.. ;) pic.twitter.com/407brMCH\u2014 Jamie Arnold (@itsallgonewrong) October 27, 2012\n\nAnd despite Jamie\u2019s questionable taste in fancy dress outfits (look closely at that board), he is a proper genius when it comes to processes and particularly agile ones. So I followed his example and instituted a home kanban board.\n\nWhat is this kanban of which you speak?\n\nKanban boards are an artefact from lean manufacturing \u2014 basically a visualisation of a production process. They are used to show you where your bottlenecks are, or where one part of the process is producing components faster than another part of the process can cope. Identifying the bottlenecks leads you to set work in progress (WIP) limits, so that you get an overall more efficient system.\n\nIncreasingly kanban is used as an agile software development approach, too, especially where support work (like fixing bugs) needs to be balanced with incremental enhancement (like adding new features).\n\nI\u2019m a big advocate of kanban when you have a system that needs to be maintained and improved by the same team at the same time. Rather than the sprint-based approach of scrum (where the next sprint\u2019s stories or features to be delivered are agreed up front), kanban lets individuals deal with incidents or problems that need investigation and bug fixing when urgent and important. Then, when someone has capacity, they can just go to the board and pull down the next feature to develop or test.\n\nSo, how did we use it?\n\nOne of the key tenets of kanban is that you visualise your workflow, so we put together a whiteboard with columns: Icebox; To Do Next; In Process; Done; and also a section called Blocked. Then, for each thing that needed to happen in the house, we put it on a Post-it note and initially chucked them all in the Icebox \u2014 a collection with no priority assigned yet.\n\nEach week we looked at the Icebox and pulled out a set of things that we felt should be done next. This was pulled into the To Do Next column, and then each time either of us had some time, we could just pull a new thing over into the In Process column. We agreed to review at the end of each week and move things to Done together, and to talk about whether this kanban approach was working for us or not.\n\nWe quickly learned for ourselves why kanban has WIP limits as a key tenet \u2014 it\u2019s tempting to pull everything into the To Do Next column, but that\u2019s unrealistic. And trying to do more than one or two things each at a given time isn\u2019t terribly productive owing to the cost of task switching. So we tend to limit our To Do Next to about seven items, and our In Process to about four (a max of two each, basically).\n\nWe use the Blocked column when something can\u2019t be completed \u2014 perhaps we can\u2019t fix something because we discovered we don\u2019t have the required tools or supplies, or if we\u2019re waiting for a call back from a plumber. But it\u2019s nice to put it to one side, knowing that it won\u2019t be forgotten.\n\nWhat helped the most?\n\nIt wasn\u2019t so much the visualisation that helped us to see what we needed to do, but the conversation that happened when we were agreeing priorities, moving them to In Process and then on to Done made the biggest difference. Getting clear on the order of importance really is invaluable \u2014 as is getting clear on what Done really means!\n\nThe Blocked column is also great, as it helps us keep track of things we need to do outside the house to make sure we can make progress. We also found it really helpful to examine the process itself and figure out whether it was working for us. For instance, one thing we realised is it\u2019s worth tracking some regular tasks that need time invested in them (like taking recycling that isn\u2019t picked up to the recycling centre) and these used to cycle around and around. So they were moved to Done as part of our weekly review, but then immediately put back in the Icebox to float back to the top again at a relevant time.\n\nBut the best thing of all? That moment where we get to mark something as done! It\u2019s immensely satisfying to review at the end of the week and have a physical marker of the progress you\u2019ve made.\n\nAll in all, a home kanban board turned out to be a very effective way to pull tasks through stages rather than always trying to plan them out in advance, and definitely made collaboration on our home tasks significantly smoother.

{"rowid": 173, "title": "Real Fonts and Rendering: The New Elephant in the Room", "contents": "My friend, the content strategist Kristina Halvorson, likes to call content \u201cthe elephant in the room\u201d of web design. She means it\u2019s the huge problem that no one on the web development team or client side is willing to acknowledge, face squarely, and plan for. \n\nA typical web project will pass through many helpful phases of research, and numerous beneficial user experience design iterations, while the content\u2014which in most cases is supposed to be the site\u2019s primary focus\u2014gets handled haphazardly at the end. Hence, elephant in the room, and hence also artist Kevin Cornell\u2019s recent use of elephantine imagery to illustrate A List Apart articles on the subject. But I digress.\n\nWithout discounting the primacy of the content problem, we web design folk have now birthed ourselves a second lumbering mammoth, thanks to our interest in \u201creal fonts on the web\u201c (the unfortunate name we\u2019ve chosen for the recent practice of serving web-licensed fonts via CSS\u2019s decade-old @font-face declaration\u2014as if Georgia, Verdana, and Times were somehow unreal). \n\nFor the fact is, even bulletproof and mo\u2019 bulletproofer @font-face CSS syntax aren\u2019t really bulletproof if we care about looks and legibility across browsers and platforms.\n\nHyenas in the Breakfast Nook\n\nThe problem isn\u2019t just that foundries have yet to agree on a standard font format that protects their intellectual property. And that, even when they do, it will be a while before all browsers support that standard\u2014leaving aside the inevitable politics that impede all standardization efforts. Those are problems, but they\u2019re not the elephant. Call them the coyotes in the room, and they\u2019re slowly  being tamed.\n\nNor is the problem that workable, scalable business models (of which Typekit\u2018s is the most visible and, so far, the most successful) are still being shaken out and tested. The quality and ease of use of such services, their stability on heavily visited sites (via massively backed-up server clusters), and the fairness and sustainability of their pricing will determine how licensing and serving \u201creal fonts\u201d works in the short and long term for the majority of designer/developers.\n\nNor is our primary problem that developers with no design background may serve ugly or illegible fonts that take forever to load, or fonts that take a long time to download and then display as ordinary system fonts (as happens on, say, about.validator.nu). Ugliness and poor optimization on the web are nothing new. That support for @font-face in Webkit and Mozilla browsers (and for TrueType fonts converted to Embedded OpenType in Internet Explorer) adds deadly weapons to the non-designer\u2019s toolkit is not the technology\u2019s fault. JavaScript and other essential web technologies are equally susceptible to abuse. \n\nBeauty is in the Eye of the Rendering Engine\n\nNo, the real elephant in the room\u2014the thing few web developers and no \u201cweb font\u201d enthusiasts are talking about\u2014has to do with legibility (or lack thereof) and aesthetics (or lack thereof) across browsers and platforms. Put simply, even fonts optimized for web use (which is a whole thing: ask a type designer) will not look good in every browser and OS. That\u2019s because every browser treats hinting differently, as does every OS, and every OS version. \n\nFirefox does its own thing in both Windows and Mac OS, and Microsoft is all over the place because of its need to support multiple generations of Windows and Cleartype and all kinds of hardware simultaneously. Thus \u201creal type\u201d on a single web page can look markedly different, and sometimes very bad, on different computers at the same company. If that web page is your company\u2019s, your opinion of \u201cweb fonts\u201d may suffer, and rightfully. (The advantage of Apple\u2019s closed model, which not everyone likes, is that it allows the company to guarantee the quality and consistency of user experience.)  \n\nAs near as my font designer friends and I can make out, Apple\u2019s Webkit in Safari and iPhone ignores hinting and creates its own, which Apple thinks is better, and which many web designers think of as \u201cwhat real type looks like.\u201d The forked version of Webkit in Chrome, Android, and Palm Pre also creates its own hinting, which is close to iPhone\u2019s\u2014close enough that Apple, Palm, and Google could propose it as a standard for use in all browsers and platforms. Whether Firefox would embrace a theoretical Apple and Google standard is open to conjecture, and I somehow have difficulty imagining Microsoft buying in\u2014even though they know the web is more and more mobile, and that means more and more of their customers are viewing web content in some version of Webkit.\n\nThe End of Simple\n\nThere are ways around this ugly type ugliness, but they involve complicated scripting and sniffing\u2014the very nightmares from which web standards and the simplicity of @font-face were supposed to save us. I don\u2019t know that even mighty Typekit has figured out every needed variation yet (although, working with foundries, they probably will). \n\nFor type foundries, the complexity and expense of rethinking classic typefaces to survive in these hostile environments may further delay widespread adoption of web fonts and the resolution of licensing and formatting issues. The complexity may also force designers (even those who prefer to own) to rely on a hosted rental model simply to outsource and stay current with the detection and programming required.\n\nForgive my tears.

{"rowid": 297, "title": "Public Speaking with a Buddy", "contents": "My book Demystifying Public Speaking focuses on the variety of fears we each have about giving a talk. From presenting to a client, to leading a team standup, to standing on a conference stage, there are lots of things we can do to prepare ourselves for the spotlight and reduce those fears.\nThough it didn\u2019t make it into the final draft, I wanted to highlight how helpful it can be to share that public speaking spotlight with another person, or a few more people. If you have fears about not knowing the answer to a question, fumbling your words, or making a mistake in the spotlight, then buddying up may be for you!\n\nTo some, adding more people to a presentation sounds like a recipe for on-stage disaster. To others, having a friendly face nearby\u2014a partner who can step in if you fumble\u2014is incredibly reassuring. As design director Yesenia Perez-Cruz writes, \u201cWhile public speaking is a deeply personal activity, you don\u2019t have to go it alone. Nothing has helped my speaking career more than turning it into a group effort.\u201d\nCo-presenting can level up a talk in two ways: an additional brain and presentation skill set can improve the content of the talk itself, and you may feel safer with the on-stage safety net of your buddy. \nFor example, when I started giving lengthy workshops about building mobile device labs with my co-worker Destiny Montague, we brought different experience to the table. I was able to talk about the user experience of our lab, and the importance of testing across different screen sizes. Destiny spoke about the hardware aspects of the lab, like power consumption and networking. Our audience benefitted from the spectrum of insight we included in the talk.\nMoreover, Destiny and I kept each other energized and engaging while teaching our audience, having way more fun onstage. Partnering up alleviated the risk (and fear!) of fumbling; where one person makes a mistake, the other person is right there to help. Buddy presentations can be helpful if you fear saying \u201cI don\u2019t know\u201d to a question, as there are other people around you who will be able to help answer it from the stage. By partnering with someone whom I trust and respect, and whose work and knowledge augments my own, it made the experience\u2014and the presentation!\u2014significantly better.\nCo-presenting won\u2019t work if you don\u2019t trust the person you\u2019re onstage with, or if you don\u2019t have good chemistry working together. It might also not work if there\u2019s an imbalance of responsibilities, both in preparing the talk and giving it. Read on for how to make partner talks work to your advantage!\nTrustworthiness\nIf you want to explore co-presenting, make sure that your presentation partner is trustworthy and can carry their weight; it can be stressful if you find yourself trying to meet deadlines and prepare well and your partner isn\u2019t being helpful. We\u2019re all about reducing the fears and stress levels surrounding being in that spotlight onstage; make sure that the person you\u2019re relying on isn\u2019t making the process harder.\nBefore you start working together, sketch out the breakdown of work and timeline you\u2019re each committing to. Have a conversation about your preferred work style so you each have a concrete understanding of the best ways to communicate (in what medium, and how often) and how to check in on each other\u2019s progress without micromanaging or worrying about radio silence. Ask your buddy how they prefer to receive feedback, and give them your own feedback preferences, so neither of you are surprised or offended when someone\u2019s work style or deliverable needs to be tweaked.\nThis should be a partnership in which you both feel supported; it\u2019s healthy to set all these expectations up front, and create a space in which you can each tweak things as the work progresses.\nTalk flow and responsibilities\nThere are a few different ways to organize the structure of your talk with multiple presenters. Start by thinking about the breakdown of the talk content\u2014are there discrete parts you and the other presenters can own or deliver? Or does it feel more appropriate to deliver the entirety of the content together?\nIf you\u2019re finding that you can break down the content into discrete chunks, figure out who should own which pieces, and what ownership means. Will you develop the content together but have only one person present the information? Or will one person research and prepare each content section in addition to delivering it solo onstage?\nRehearse how handoffs will go between sections so it feels natural, rather than stilted. I like breaking a presentation into \u201cchapters\u201d when I\u2019m passionate about particular aspects of a topic and can speak on those, but know that there are other aspects to be shared and there\u2019s someone else who can handle (and enjoy!) talking about them. When Destiny and I rehearsed our \u201cchapter\u201d handoffs, we developed little jingles that we\u2019d both sing together onstage; it indicated to the audience that it was a planned transition in the content, and tied our independent work together into a partnership.\n.embed-container { position: relative; padding-bottom: 56.25%; height: 0; overflow: hidden; max-width: 100%; } .embed-container iframe, .embed-container object, .embed-container embed { position: absolute; top: 0; left: 0; width: 100%; height: 100%; }\n\n\n\nAlternatively, you can give the presentation in a way that\u2019s close to having a rehearsed conversation, rather than independently presenting discrete parts of the talk. In this case, you\u2019ll both be sharing the spotlight at the same time, throughout the duration of the talk. Preparation is key, here, to make sure that you each understand what needs to be communicated, and you have a sense of who will be taking responsibility for communicating those different pieces of information. A poorly-prepared talk like this will look like the co-presenters are talking over each other, or hesitating awkwardly to give the other person more room to speak; the audience will feel how uncomfortable this is, and will probably be distracted from the talk content. Practice the talk the whole way through multiple times so you know what each person is planning on covering and how you want to interact with each other while you\u2019re both holding microphones; also figure out how you\u2019ll be standing in relation to each other. More on that next!\nSharing the stage\nIf you choose to give a talk with a partner, determine ahead of time how you\u2019ll stand (or sit). For example, if you each take \u201cchapters\u201d or major sections of the presentation, ensure that it\u2019s clear who the audience should focus their attention on. You could sit in a chair off to the side (or stand). I recommend placing yourself far enough away that you\u2019re not distracting to the audience; you don\u2019t want them watching you while your partner is speaking. If the audience can still see you, but their focus should be on your buddy, be sure to not look distracted; keep your eyes on your buddy, and don\u2019t just open your laptop and ignore what\u2019s happening! Feel free to smile, laugh, or react how the audience should be reacting as your partner is speaking.\nIf you\u2019re both sharing the spotlight at the same time and having a rehearsed conversation, make sure that your body language engages the audience and you\u2019re not just speaking to each other, ignoring the folks watching. Watch this talk with Guy Podjarny and Assaf Hefetz who have partnered up to talk about security; they have clearly identified roles onstage, and remain engaged with the audience.\n\nConsider whether or not you will share a microphone, or if you will both be mic\u2019d. (Be sure that the event organizer, or the A/V team, has a heads-up well in advance to ensure they have the equipment handy!) Also talk through how you\u2019d like to handle Q&A time during or after the talk, especially if you have clear \u201cchapters\u201d where Q&A might happen naturally during a handoff. The more clarity you and your partner have about who is responsible for which pieces of information sharing, the more you can feel and appear prepared.\nCo-presenting does take a lot of preparation and requires a ton of communication between you and your partner.

Everything from writing new documentation, drawing diagrams, and holding technical architecture sessions teaches you something you didn\u2019t know or exposes an area of uncertainty that you can go work on.\nIn this article, I hope to share some experiences and techniques that will prove useful in your own situation and that you can impress your friends in some new and exciting ways!\nHow do you do, fellow kids?\nTo start with I\u2019d like to introduce you to our JavaScript framework, Flight. Right now it\u2019s used by twitter.com and TweetDeck although, as a company, Twitter is largely moving to React.\nOver time, as we used Flight for more complex interfaces, we found it wasn\u2019t scaling with us.\nComposing components into trees was fiddly and often only applied for a specific parent-child pairing. It seems like an obvious feature with hindsight, but it didn\u2019t come built-in to Flight, and it made reusing components a real challenge.\nThere was no standard way to manage the state of a component; they all did it slightly differently, and the technique often varied by who was writing the code. This cost us in maintainability as you just couldn\u2019t predict how a component would be built until you opened it.\nMaking matters worse, Flight relied on events to move data around the application. Unfortunately, events aren\u2019t good for giving structure to complex logic. They jump around in a way that\u2019s hard to understand and debug, and force you to search your code for a specific string \u2014 the event name\u201a to figure out what\u2019s going on.\nTo find fixes for these problems, we looked around at other frameworks. We like React for it\u2019s simple, predictable state management and reactive re-render flow, and Elm for bringing strict functional programming to everyone.\nBut when you have lots of existing code, rewriting or switching framework is a painful and expensive option. You have to understand how it will interact with your existing code, how you\u2019ll test it alongside existing code, and how it will affect the size and performance of the application. This all takes time and effort!\nInstead of planning a rewrite, we looked for the ideas hidden within other frameworks that we could reapply in our own situation or bring to the tools we already were using.\nBoiled down, what we liked seemed quite simple:\n\nComponent nesting & composition\nEasy, predictable state management\nNormal functions for data manipulation\n\nMaking these ideas applicable to Flight took some time, but we\u2019re in a much better place now. Through persistent trial-and-error, we have well documented, testable and standard techniques for creating complex component hierarchies, updating and reacting to state changes, and passing data around the app.\nWhile the specifics of our situation and Flight aren\u2019t really important, this experience taught me something: \n\nDistill good tech into great ideas. You can apply great ideas anywhere.\n\nYou don\u2019t have to use cool kids\u2019 latest framework, hottest build tool or fashionable language to benefit from them. If you can identify a nugget of gold at the heart of it all, why not use it to improve what you have already?\nTimes, they are a changin\u2019\nApart from stealing ideas from the new and shiny, how can we keep make the most of improved tooling and techniques? Times change and so should the way we write code.\nGoing back in time a bit, TweetDeck used some slightly outmoded tools for building and bundling. Without a transpiler like Babel we were missing out new language features, and without a more advanced build tools like Webpack, every module\u2019s source was encased in AMD boilerplate.\nIn fact, we found ourselves with a mix of both AMD syntaxes:\ndefine([\"lodash\"], function (_) {\n  // . . .\n});\n\ndefine(function (require) {\n  var _ = require(\"lodash\");\n  // . . .\n});\nThis just wouldn\u2019t do. And besides, what we really wanted was CommonJS, or even ES2015 module syntax:\nimport _ from \"lodash\";\nThese days we\u2019re using Babel, Webpack, ES2015 modules and many new language features that make development just\u2026 better. But how did we get there?\nTo explain, I want to introduce you to codemods and jscodeshift.\nA codemod is a large-scale refactor of a whole codebase, often mechanical or repetitive. Think of renaming a module or changing an API like URL(\"...\") to new URL(\"...\").\njscodeshift is a toolkit for running automated codemods, where you express a code transformation using code. The automated codemod operates on each file\u2019s syntax tree \u2013 a data-structure representation of the code \u2014 finding and modifying in place as it goes.\nHere\u2019s an example that renames all instances of the variable foo to bar:\nmodule.exports = function (fileInfo, api) {\n  return api\n    .jscodeshift(fileInfo.source)\n    .findVariableDeclarators('foo')\n    .renameTo('bar')\n    .toSource();\n};\nIt\u2019s a seriously powerful tool, and we\u2019ve used it to write a series of codemods that:\n\nrename modules,\nunify our use of AMD to a single syntax,\ntransition from one testing framework to another, and\nswitch from AMD to CommonJS.\n\nThese changes can be pretty huge and far-reaching. Here\u2019s an example commit from when we switched to CommonJS:\ncommit 8f75de8fd4c702115c7bf58febba1afa96ae52fc\nDate:   Tue Jul 12 2016\n\n   Run AMD -> CommonJS codemod\n\n 418 files changed, 47550 insertions(+), 48468 deletions(-)\n\nYep, that\u2019s just under 50k lines changed, tested, merged and deployed without any trouble. AMD be gone!\n\nFrom this step-by-step approach,  using codemods to incrementally tweak and improve, we extracted a little codemod recipe for making significant, multi-stage changes:\n\nFind all the existing patterns\nChoose the two most similar\nUnify with a codemod\nRepeat.\n\nFor example:\n\nFor module loading, we had 2 competing AMD patterns plus some use of CommonJS\nThe two AMD syntaxes were the most similar\nWe used a codemod to move to unify the AMD patterns\nLater we returned to AMD to convert it to CommonJS\n\nIt\u2019s worked for us, and if you\u2019d like to know more about codemods then check out Evolving Complex Systems Incrementally by Facebook engineer, Christoph Pojer.\nWelcome aboard!\nAs TweetDeck has gotten older and larger, the amount of things a new engineer has to learn about has exploded. The myriad of microservices that manage our data and their layers of authentication, security and business logic around them make for an overwhelming amount of information to hand to a newbie.\nInspired by Amy\u2019s amazing Guide to the Care and Feeding of Junior Devs, we realised it was important to take time to design our onboarding that each of our new hires go through to make the most of their first few weeks.\nJoining a new company, team, or both, is stressful and uncomfortable. Everything you can do to help a new hire will be valuable to them. So please, take time to design your onboarding!\nAnd as you build up an onboarding process, you\u2019ll create things that are useful for more than just new hires; it\u2019ll force you to write documentation, for example, in a way that\u2019s understandable for people who are unfamiliar with your team, product and codebase. This can lead to more outside contributions: potential contributors feel more comfortable getting set up on your product without asking for help.\nThis is something that\u2019s taken for granted in open source, but somehow I think we forget about it in big companies.\nAfter all, better documentation is just a good thing. You will forget things from time to time, and you\u2019d be surprised how often the \u201cbeginner\u201d docs help!\nFor TweetDeck, we put together system and architecture diagrams, and one-pager explanations of important concepts:\n\nWhat are our dependencies?\nWhere are the potential points of failure?\nWhere does authentication live? Storage? Caching?\nWho owns \u201cX\u201d?\n\n\nOf course, learning continues long after onboarding. The landscape is constantly shifting; old services are deprecated, new APIs appear and what once true can suddenly be very wrong. Keeping up with this is a serious challenge, and more than any one person can track.\nTo address this, we\u2019ve thought hard about our knowledge sharing practices across the whole team. For example, we completely changed the way we do code review.\nIn my opinion, code review is the single most effective practice you can introduce to share knowledge around, and build the quality and consistency of your team\u2019s work. But, if you\u2019re not doing it, here\u2019s my suggestion for getting started:\n\nEvery pull request gets a +1 from someone else.\n\nThat\u2019s all \u2014 it\u2019s very light-weight and easy. Just ask someone to have a quick look over your code before it goes into master.\nAt Twitter, every commit gets a code review. We do a lot of reviewing, so small efficiency and effectiveness improvements make a big difference. Over time we learned some things:\n\nDon\u2019t review for more than hour 1\nKeep reviews smaller than ~400 lines 2\nCode review your own code first 2\n\nAfter an hour, and above roughly 400 lines, your ability to detect issues in a code review starts to decrease. So review little and often. The gaps around lunch, standup and before you head home are ideal. And remember, if someone\u2019s put code up for a review, that review is blocking them doing other work. It\u2019s your job to unblock them.\nOn TweetDeck, we actually try to keep reviews under 250 lines. It doesn\u2019t sound like much, but this constraint applies pressure to make smaller, incremental changes. This makes breakages easier to detect and roll back, and leads to a very natural feature development process that encourages learning and iteration.\nBut the most important thing I\u2019ve learned personally is that reviewing my own code is the best way to spot issues. I try to approach my own reviews the way I approach my team\u2019s: with fresh, critical eyes, after a break, using a dedicated code review tool.\nIt\u2019s amazing what you can spot when you put a new in a new interface around code you\u2019ve been staring at for hours!\nAnd yes, this list features science. The data backs up these conclusions, and if you\u2019d like to learn more about scientific approaches to software engineering then I recommend you buy Making Software: What Really Works, and Why We Believe It. It\u2019s ace.\nFor more dedicated information sharing, we\u2019ve introduced regular seminars for everyone who works on a specific area or technology. It works like this: a team-member shares or teaches something to everyone else, and next time it\u2019s someone else\u2019s turn. Giving everyone a chance to speak, and encouraging a wide range of topics, is starting to produce great results.\nIf you\u2019d like to run a seminar, one thing you could try to get started: run a point at the thing you least understand in our architecture session \u2014 thanks to James for this idea. And guess what\u2026 your onboarding architecture diagrams will help (and benefit from) this!\nMore, please!\nThere\u2019s a few ideas here to get you started, but there are even more in a talk I gave this year called Frontend Archaeology, including a look at optimising for confidence with front-end operations.\nAnd finally, thanks to Amy for proof reading this and to Passy for feedback on the original talk.\n\n\n\n\nDunsmore et al. 2000.

{"rowid": 58, "title": "Beyond the Style Guide", "contents": "Much like baking a Christmas cake, designing for the web involves creating an experience in layers. Starting with a solid base that provides the core experience (the fruit cake), we can add further layers, each adding refinement (the marzipan) and delight (the icing).\nDon\u2019t worry, this isn\u2019t a misplaced cake recipe, but an evaluation of modular design and the role style guides can play in acknowledging these different concerns, be they presentational or programmatic.\nThe auteur\u2019s style guide\nAlthough trained as a graphic designer, it was only when I encountered the immediacy of the web that I felt truly empowered as a designer. Given a desire to control every aspect of the resulting experience, I slowly adopted the role of an auteur, exploring every part of the web stack: front-end to back-end, and everything in between. A few years ago, I dreaded using the command line. Today, the terminal is a permanent feature in my Dock.\nIn straddling the realms of graphic design and programming, it\u2019s the point at which they meet that I find most fascinating, with each dicipline valuing the creation of effective systems, be they for communication or code efficiency. Front-end style guides live at this intersection, demonstrating both the modularity of code and the application of visual design.\nPainting by numbers\nIn our rush to build modular systems, design frameworks have grown in popularity. While enabling quick assembly, these come at the cost of originality and creative expression \u2013 perhaps one reason why we\u2019re seeing the homogenisation of web design.\nIn editorial design, layouts should accentuate content and present it in an engaging manner. Yet on the web we see a practice that seeks templated predictability. In \u2018Design Machines\u2019 Travis Gertz argued that (emphasis added):\n\nDesign systems still feel like a novelty in screen-based design. We nerd out over grid systems and modular scales and obsess over style guides and pattern libraries. We\u2019re pretty good at using them to build repeatable components and site-wide standards, but that\u2019s sort of where it ends. [\u2026] But to stop there is to ignore the true purpose and potential of a design system.\n\nUnless we consider how interface patterns fully embrace the design systems they should be built upon, style guides may exacerbate this paint-by-numbers approach, encouraging conformance and suppressing creativity.\nAnatomy of a button\nLet\u2019s take a look at that most canonical of components, the button, and consider what we might wish to document and demonstrate in a style guide.\nThe different layers of our button component.\nContent\nThe most variable aspect of any component. Content guidelines will exert the most influence here, dictating things like tone of voice (whether we should we use stiff, formal language like \u2018Submit form\u2019, or adopt a more friendly tone, perhaps \u2018Send us your message\u2019) and appropriate language. For an internationalised interface, this may also impact word length and text direction or orientation.\nStructure\nHTML provides a limited vocabulary which we can use to structure content and add meaning. For interactive elements, the choice of element can also affect its behaviour, such as whether a button submits form data or links to another page:\n<button type=\"submit\">Button text</button>\n<a href=\"/index.html\">Button text</a>\nNote: One of the reasons I prefer to use <button> instead of <input type=\u201cbutton\u201d>, besides allowing the inclusion of content other than text, is that it has a markup structure similar to links, therefore keeping implementation differences to a minimum.\nWe should also think about each component within the broader scope of our particular product. For this we can employ a further vocabulary, which can be expressed by adding values to the class attribute. For a newspaper, we might use names like lede, standfirst and headline, while a social media application might see us reach for words like stream, action or avatar.\nPresentation\nThe appearance of a component can never be considered in isolation. Informed by its relationship to other elements, style guides may document different stylistic variations of a component, even if the underlying function remains unchanged: primary and secondary button styles, for example.\nBehaviour\nA component can exhibit various states: blank, loading, partial, error and ideal, and a style guide should reflect that. Our button component is relatively simple, yet even here we need to consider hover, focused, active and disabled states.\nTranscending layers\nThis overview reinforces Ethan\u2019s note from earlier in this series:\n\nI\u2019ve found that thinking about my design as existing in broad experience tiers \u2013 in layers \u2013 is one of the best ways of designing for the modern web.\n\nWhile it\u2019s tempting to describe a component as series of layers, certain aspects will transcend several of these. The accessibility of a component, for example, may influence the choice of language, the legibility of text, colour contrast and which affordances are provided in different states.\nVisual design language: documenting the missing piece\nEven given this small, self-contained component, we can see several concerns at play, and in reviewing our button it seems we have most things covered. However, a few questions remain unanswered. Why does it have a blue background? Why are the borders 2px thick, with a radius of 4px? Why are we using that font, at that size and with that weight?\nThese questions can be answered by our visual design language. More than a set of type choices and colour palettes, a design language can dicate common measures, ratios and the resulting grid(s) these influence. Ideally governed by a set of broader design principles, it can also inform an illustration style, the type of photography sourced or commissioned, and the behaviour of any animations.\nWhereas a style guide ensures conformity, having it underpinned by an effective design language will allow for flexibility; only by knowing the rules can you know how to break them!\nType pairings in the US Web Design Standards guide.\nFor a style guide to thoroughly articulate a visual design system, the spectrum of choices it allows for should be acknowledged. A fantastic example of this can be found in the US Web Design Standards. By virtue of being a set of standards designed to apply to a number of different sites, this guide offers a range of type pairings (that take into account performance considerations) and provides primary, secondary and tertiary palette relationships, with shades and tones thereof:\nColour palettes in the US Web Design Standards guide.\nA visual language in code form\nProperly documenting our design language in a style guide is a good start, yet even better if it can be expressed in code. This is where CSS preprocessors become a powerful ally.\nIn Sass, methods like mixins and maps can help us represent relationships between values. Variables (and CSS variables) extend the vocabulary provided natively by CSS, meaning we can describe patterns in terms of our own visual language. These tools effectively become an interface to our design system. Furthermore, they help maintain a separation of concerns, with visual presentation remaining where it should be: in our style sheets.\nTake this simple example, an article summary on a website counting down the best Christmas movies:\nThe design for our simple component example.\nOur markup is as follows, using appropriate semantic HTML elements and incorporating the vocabulary from our collection of design patterns (expressed using the BEM methodology):\n<article class=\"summary\">\n    <h1 class=\"summary__title\">\n        <a href=\"scrooged.html\">\n            <span class=\"summary__position\">12</span>\n            Scrooged (1988)\n        </a>\n    </h1>\n\n    <div class=\"summary__body\">\n        <p>It\u2019s unlikely that Bill Murray could ever have got through his career without playing a version of Scrooge\u2026</p>\n    </div>\n\n    <footer class=\"summary__meta\">\n        <strong>Director:</strong> Richard Donner<br/>\n        <strong>Stars:</strong> Bill Murray, Buddy Hackett, Karen Allen\n    </footer>\n</article>\nWe can then describe the presentation of this HTML by using Sass maps to define our palettes, mixins to include predefined font metrics, and variables to recall common measurements:\n.summary {\n    margin-bottom: ($baseline * 4)\n}\n\n.summary__title {\n    @include font-family(display-serif);\n    @include font-size(title);\n    color: palette(neutral, dark);\n    margin-bottom: ($baseline * 4);\n    border-top: $rule-height solid palette(primary, purple);\n    padding-top: ($baseline * 2);\n}\n\n.summary__position {\n    @include font-family(display-sans, 300);\n    color: palette(neutral, mid);\n}\n\n.summary__body {\n    @include font-family(text-serif);\n    @include font-size(body);\n    margin-bottom: ($baseline * 2);\n}\n\n.summary__meta {\n    @include font-family(text-sans);\n    @include font-size(caption);\n}\nOf course, this is a simplistic example for the purposes of demonstration. However, such thinking was employed at a much larger scale at the Guardian. Using a set of Sass components, complex patterns could be described using a language familar to everyone on the product team, be they a designer, developer or product owner:\nThe design of a component on the Guardian website, described in terms of its Sass-powered design system.\nUnlocking possibility\nAlongside tools like preprocessors, newer CSS layout modules like flexbox and grid layout mean the friction we\u2019ve long been accustomed to when creating layouts on the web is no longer present, and the full separation of presentation from markup is now possible. Now is the perfect time for graphic designers to advocate design systems that these developments empower, and ensure they\u2019re fully represented in both documentation and code. That way, together, we can build systems that allow for greater visual expression. After all, there\u2019s more than one way to bake a Christmas cake.", "year": "2015", "author": "Paul Lloyd", "author_slug": "paulrobertlloyd", "published": "2015-12-16T00:00:00+00:00", "url": "https://24ways.org/2015/beyond-the-style-guide/", "topic": "design"}
{"rowid": 34, "title": "Collaborative Responsive Design Workflows", "contents": "Much has been written about workflow and designer-developer collaboration in web design, but many teams still struggle with this issue; either with how to adapt their internal workflow, or how to communicate the need for best practices like mobile first and progressive enhancement to their teams and clients. Christmas seems like a good time to have another look at what doesn\u2019t work between us and how we can improve matters.\n\nWhy is it so difficult?\n\nWe\u2019re still beginning to understand responsive design workflows, acknowledging the need to move away from static design tools and towards best practices in development. It\u2019s not that we don\u2019t want to change\u00a0\u2013 so why is it so difficult?\n\nChanging the way we do something that has become routine is always problematic, even with small things, and the changes today\u2019s web environment requires from web design and development teams are anything but small.\n\nAlthough developers also have a host of new skills to learn and things to consider, designers are probably the ones pushed furthest out of their comfort zones: as well as graphic design, a web designer today also needs an understanding of interaction design and ergonomics, because more and more websites are becoming tools rather than pages meant to be read like a book or magazine. In addition to that there are thousands of different devices and screen sizes on the market today that layout and interactions need to work on.\n\nThese aspects make it impossible to design in a static design tool, so beyond having to learn about new aspects of design, the designer has to either learn how to code or learn to work with a responsive design tool.\n\nWhy do it\n\nThat alone is enough to leave anyone overwhelmed, as learning a new skill takes time and slows you down in a project \u2013 and on most projects time is in short supply. Yet we have to make time or fall behind in the industry as others pitch better, interactive designs. For an efficient workflow, both designers and developers must familiarise themselves with new tools and techniques.\n\nA designer has to be able to play with ideas, make small adjustments here and there, look at the result, go back to the settings and make further adjustments, and so on. You can only realistically do that if you are able to play with all the elements of a design, including interactivity, accessibility and responsiveness.\n\nFiguring out the right breakpoints in a layout is one of the foremost reasons for designing in a responsive design tool. Even if you create layouts for three viewport sizes (i.e. smartphone, tablet and the most common desktop size), you\u2019d only cover around 30% of visitors and you might miss problems like line breaks and padding at other viewport sizes.\n\nAnother advantage is consistency. In static design tools changes will not be applied across all your other layouts. A developer referring back to last week\u2019s comps might work with outdated metrics. Furthermore, you cannot easily test what impact changes might have on previously designed areas. In a dynamic design tool such changes will be applied to the entire design and allow you to test things in site areas you had already finished.\n\nNo static design tool allows you to do this, and having somebody else produce a mockup from your static designs or wireframes will duplicate work and is inefficient.\n\nHow to do it\n\nWhen working in a responsive design tool rather than in the browser, there is still the question of how and when to communicate with the developer. I have found that working with Sass in combination with a visual style guide is very efficient, but it does need careful planning: fundamental metrics for padding, margins and font sizes, but also design elements like sliders, forms, tabs, buttons and navigational elements, should be defined at the beginning of a project and used consistently across the site. Working with a grid can help you develop a consistent design language across your site.\n\nCreate a visual style guide that shows what the elements look like and how they behave across different screen sizes \u2013 and when interacted with. Put all metrics on paddings, margins, breakpoints, widths, colours and so on in a text document, ideally with names that your developer can use as Sass variables in the CSS. For example:\n\n$padding-default-vertical: 1.5em;\n\nDevelopers, too, need an efficient workflow to keep code maintainable and speed up the time needed for more complex interactions with an eye on accessibility and performance. CSS preprocessors like Sass allow you to work with variables and mixins for default rules, as well as style sheet partials for different site areas or design elements. Create your own boilerplate to use for your projects and then update your variables with the information from your designer for each individual project.\n\nHow to get buy-in\n\nOne obstacle when implementing responsive design, accessibility and content strategy is the logistics of learning new skills and iterating on your workflow. Another is how to sell it. You might expect everyone on a project (including the client) to want to design and develop the best website possible: ultimately, a great site will lead to more conversions. However, we often hear that people find it difficult to convince their teammates, bosses or clients to implement best practices.\n\nWhy is that? Well, I believe a lot of it is down to how we sell it. You will have experienced this yourself: some people you trust to know what they are talking about, and others you don\u2019t. Think about why you trust that first person but don\u2019t buy what the other one is telling you. It is likely because person A has a self-assured, calm and assertive demeanour, while person B seems insecure and apologetic. To sell our ideas, we need to become person A! For a timid designer or developer suffering from imposter syndrome (like many of us do in this industry) that is a difficult task. So how can we become more confident in selling our expertise?\n\nWrite\n\nWe need to become experts. And I mean not just in writing great code or coming up with beautiful designs but at explaining why we\u2019re doing what we\u2019re doing. Why do you code this way or that? Why is this the best layout? Why does a website have to be accessible and responsive? Write about it. Putting your thoughts down on paper or screen is a really efficient way of getting your head around a topic and learning to make a case for something. You may even find that you come up with new ideas as you are writing, so you\u2019ll become a better designer or developer along the way.\n\nTalk\n\nThen, talk about it. Start out in front of your team, then do a lightning talk at a web event near you, then a longer talk or workshop. Having to talk about a topic is going to help you put into spoken words the argument that you\u2019ve previously put together in writing. Writing comes more easily when you\u2019re starting out but we use a different register when writing than talking and you need to learn how to speak your case. Do the talk a couple of times and after each talk make adjustments where you found it didn\u2019t work well. By this time, you are more than ready to make your case to the client. In fact, you\u2019ve been ready since that first talk in front of your colleagues ;)\n\nPitch\n\nPitches used to be based on a presentation of static layouts for for three to five typical pages and three different designs. But if we want to sell interactivity, structure, usability, accessibility and responsiveness, we need to demonstrate these things and I believe that it can only do us good. I have seen a few pitches sitting in the client\u2019s chair and static layouts are always sort of dull. What makes a website a website is the fact that I can interact with it and smooth interactions or animations add that extra sparkle.\n\nI can\u2019t claim personal experience for this one but I\u2019d be bold and go for only one design. One demo page matching the client\u2019s corporate design but not any specific page for the final site. Include design elements like navigation, photography, typefaces, article layout (with real content), sliders, tabs, accordions, buttons, forms, tables (yes, tables) \u2013 everything you would include in a style tiles document, only interactive. Demonstrate how the elements behave when clicked, hovered and touched, and how they change across different screen sizes. You may even want to demonstrate accessibility features like tabbed navigation and screen reader use.\n\nObviously, there are many approaches that will work in different situations but don\u2019t give up on finding a process that works for you and that ultimately allows you to build delightful, accessible, responsive user experiences for the web. Make time to try new tools and techniques and don\u2019t just work on them on the side \u2013 start using them on an actual project. It is only when we use a tool or process in the real world that we become true experts.

{"rowid": 272, "title": "Crafting the Front-end", "contents": "Much has been spoken and written recently about the virtues of craftsmanship in the context of web design and development. It seems that we as fabricators of the web are finally tiring of seeking out parallels between ourselves and architects, and are turning instead to the fabled specialist artisans.\n\nIdentifying oneself as a craftsman or craftswoman (let\u2019s just say craftsperson from here onward) will likely be a trend of early 2012. In this pre-emptive strike, I\u2019d like to expound on this movement as I feel it pertains to front-end development, and encourage care and understanding of the true qualities of craftsmanship (craftspersonship).\n\nThe core values\n\nI\u2019ll begin by defining craftspersonship. What distinguishes a craftsperson from a technician? Dictionaries tend to define a craftsperson as one who possesses great skill in a chosen field. The badge of a craftsperson for me, though, is a very special label that should be revered and used sparingly, only where it is truly deserved. A genuine craftsperson encompasses a few other key traits, far beyond raw skill, each of which must be learned and mastered.\n\nA craftsperson has: \n\n\n\tAn appreciation of good work, in both the work of others and their own. And not just good as in \u2018hey, that\u2019s pretty neat\u2019, I mean a goodness like a shining purity \u2013 the kind of good that feels right when you see it.\n\tA belief in quality at every level: every facet of the craftsperson\u2019s product is as crucial as any other, without exception, even those normally hidden from view.\n\tVision: an ability to visualize their path ahead, pre-empting the obstacles that may be encountered to plan a route around them.\n\tA preference for simplicity: an almost Bauhausesque devotion to undecorated functionality, with no unjustifiable parts included.\n\tSincerity: producing work that speaks directly to its purpose with flawless clarity.\n\n\nOnly when you become a custodian of such values in your work can you consider calling yourself a craftsperson. Now let\u2019s take a look at some steps we front-end developers can take on our journey of enlightenment toward craftspersonhood.\n\n Speaking of the craftsman\u2019s journey, be sure to watch out for the video of The Standardistas\u2019 stellar talk at the Build 2011 conference titled The Journey, which should be online sometime soon.\n\nBuilding your own toolbox\n\nMy grandfather was a carpenter and trained as a young apprentice under a master. After observing and practising the many foundation theories, principles and techniques of carpentry, he was tasked with creating his own set of woodworking tools, which he would use and maintain throughout his career. By going through the process of having to create his own tools, he would be connected at the most direct level with every piece of wood he touched, his tools being his own creations and extensions of his own skilled hands. The depth of his knowledge of these tools must have surpassed the intricate as he fathered, used, cleaned and repaired them, day in and day out over many years.\n\nAnd so it should be, ideally, with all crafts. We must understand our tools right down to the most fundamental level. I firmly believe that a level of true craftsmanship cannot be reached while there exists a layer that remains not wholly understood between a creator and his canvas. Of course, our tools as front-end developers are somewhat more complex than those of other crafts \u2013 it may seem reasonable to require that a carpenter create his or her own set of chisels, but somewhat less so to ask a front-end developer to code their own CSS preprocessor, or design their own computer.\n\nHowever, it is still vitally important that you understand how your tools work. This is particularly critical when it comes to things like preprocessors, libraries and frameworks which aim to save you time by automating common processes and functions. For the most part, anything that saves you time is a Good Thing\u2122 but it cannot be stressed enough that using tools like these in earnest should be avoided until you understand exactly what they are doing for you (and, to an extent, how they are doing it). \n\nIn particular, you must understand any drawbacks to using your tools, and any shortcuts they may be taking on your behalf. I\u2019m not suggesting that you steer clear of paid work until you\u2019ve studied each of jQuery\u2019s 9,266 lines of JavaScript source code but, all levity aside, it will further you on your journey to look at interesting or relevant bits of jQuery, and any other libraries you might want to use. Such libraries often directly link to corresponding sections of their source code on sites like GitHub from their official documentation. Better yet, they\u2019re almost always written in high level languages (easy to read), so there\u2019s no excuse not to don your pith helmet and go on something of an exploration. Any kind of tangential learning like this will drive you further toward becoming a true craftsperson, so keep an open mind and always be ready to step out of your comfort zone.\n\nDowntime and tool honing\n\nWith any craft, it is essential to keep your tools in good condition, and a good idea to stay up-to-date with the latest equipment. This is especially true on the web, which, as we like to tell anyone who is still awake more than a minute after asking what it is that we do, advances at a phenomenal pace. A tool or technique that could be considered best practice this week might be the subject of haughty derision in a comment thread within six months.\n\nI have little doubt that you already spend a chunk of time each day keeping up with the latest material from our industry\u2019s finest Interblogs and Twittertubes, but do you honestly put aside time to collect bookmarks and code snippets from things you read into a slowly evolving toolbox? At @media in 2009, Simon Collison delivered a candid talk on his \u2018Ultimate Package\u2019. Those of us who didn\u2019t flee the room anticipating a newfound and unwelcome intimacy with the contents of his trousers were shown how he maintained his own toolkit \u2013 a collection of files and folders all set up and ready to go for a new project. By maintaining a toolkit in this way, he has consistency across projects and a dependable base upon which to learn and improve.\n\nThe assembly and maintenance of such a personalized and familiar toolkit is probably as close as we will get to emulating the tool making stage of more traditional craft trades. Keep a master copy of your toolkit somewhere safe, making copies of it for new projects. When you learn of a way in which part of it can be improved, make changes to the master copy.\n\nSimplicity through modularity\n\nI believe that the user interfaces of all web applications should be thought of as being made up primarily of modular components. Modules in this context are patterns in design that appear repeatedly throughout the app. These can be small collections of elements, like a user profile summary box (profile picture, username, meta data), as well as atomic elements such as headings and list items.\n\nWell-crafted front-end architectures have the ability to support this kind of repeating pattern as modules, with as close to no repetition of CSS (or JavaScript) as possible, and as close to no variations in HTML between instances as possible.\n\nOne of the most fundamental and well known tenets of software engineering is the DRY rule \u2013 don\u2019t repeat yourself. It requires that \u201cevery piece of knowledge must have a single, unambiguous, authoritative representation within a system.\u201d \n\nAs craftspeople, we must hold this rule dear and apply it to the modules we have identified in our site designs. The moment you commit a second style definition for a module, the quality of your output (the front-end code) takes a huge hit. There should only ever be one base style definition for each distinct module or component. Keep these in a separate, sacred place in your CSS. I use a _modules.scss Sass include file, imported near the top of my main CSS files.\n\nBe sure, of course, to avoid making changes to this file lightly, as the smallest adjustment can affect multiple pages (hint: keep a structure list of which modules are used on which pages). Avoid the inevitable temptation to duplicate code late in the project. Sticking to this rule becomes more important the more complex the codebase becomes.\n\nIf you can stick to this rule, using sensible class names and consistent HTML, you can reach a joyous, self-fulfilling plateau stage in each project where you are assembling each interface from your own set of carefully crafted building blocks.\n\nOld school markup\n\nLet\u2019s take a step back. Before we fret about creating a divinely pure modular CSS framework, we need to know the site\u2019s design and what it is made of. The best way to gain this knowledge is to go old school. Print out every comp, mockup, wireframe, sketch or whatever you have. If there are sections of pages that are hidden until some user action takes place, or if the page has multiple states, be sure that you have everything that could become visible to the user on paper.\n\nOnce you have your wedge of paper designs, lay out all the pages on the floor, or stick them to the wall if you can, arranging them logically according to the site hierarchy, by user journey, or whatever guidelines make most sense to you. Once you have the site laid out before you, study it for a while, familiarizing yourself with every part of every interface. This will eliminate nasty surprises late in the project when you realize you\u2019ve duplicated something, or left an interface on the drawing board altogether.\n\nNow that you know the site like it\u2019s your best friend, get out your pens or pencils of choice and attack it. Mark it up like there\u2019s no tomorrow. Pretend you\u2019re a spy trying to identify communications from an enemy network hiding their messages in newspapers. Look for patterns and similarities, drawing circles around them. These are your modules. Start also highlighting the differences between each instance of these modules, working out which is the most basic or common type that will become the base definition from which all other representations are extended.\n\nThis simple but empowering exercise will equip you for your task of actually crafting, instead of just building, the front-end. Without the knowledge gained from this kind of research phase, you will be blundering forward, improvising as best you can, but ultimately making quality-compromising mistakes that could have been avoided.\n\nFor more on this theme, read Anna Debenham\u2019s Front-end Style Guides which recommends a similar process, and the sublime idea of extending this into a guide to refer to during development and beyond.\n\nDesign homogeneity\n\nMoving forward again, you now have your modules defined and things are looking good. I mentioned that many instances of these modules will carry minor differences. These differences must be given significant thinking time, and discussion time with your designer(s).\n\nIt should be common knowledge by now that successful software projects are not the product of distinct design and build phases with little or no bidirectional feedback. The crucial nature of the designer-developer relationship has been covered in depth this year by Paul Robert Lloyd, and a joint effort from both teams throughout the project lifecycle is pivotal to your ability to craft and ship successful products.\n\nThis relationship comes into play when you\u2019re well into the development of the site, and you start noticing these differences between instances of modules (they\u2019ll start to stand out very clearly to you and your carefully regimented modular CSS system). Before you start overriding your base styles, question the differences with the designer to work out why they exist. Perhaps they are required and are important to their context, but perhaps they were oversights from earlier design revisions, or simple mistakes.\n\nThe craftsperson\u2019s gland\n\nAs you grow towards the levels of expertise and experience where you can proudly and honestly consider yourself a craftsperson, you will find that you steadily develop what initially feels like a kind of sixth sense. I think of it more as a new hormonal gland, secreting into your bloodstream a powerful messenger chemical that can either reward or punish your brain. This gland is connected directly to your core understanding of what good quality work looks and feels like, an understanding that itself improves with experience. \n\nThis gland will make itself known to you in two ways. First, when you solve a problem in a beautifully elegant way with clean and unobtrusive code that looks good and just feels right, your craftsperson\u2019s gland will ooze something delicious that makes your brain and soul glow from the inside out. You will beam triumphantly at the succinct lines of code on your computer display before bounding outside with a spring in your step to swim up glittering rainbows and kiss soft fluffy puppies.\n\nThe second way that you may become aware of your craftsperson\u2019s gland, though, is somewhat less pleasurable. In an alternate reality, your parallel self is faced with the same problem, but decides to take a shortcut and get around it by some dubious means \u2013 the kind of technical method that the words hack, kludge and bodge are reserved for. As soon as you have done this, or even as you are doing it, your craftsperson\u2019s gland will damn well let you know that you took the wrong fork in the road. As your craftsperson\u2019s gland begins to secrete a toxic pus, you will at first become entranced into a vacant stare at the monstrous mess you are considering unleashing upon your site\u2019s visitors, before writhing in the horrible agony of an itch that can never be scratched, and a feeling of being coated with the devil\u2019s own deep and penetrating filth that no shower will ever cleanse.\n\nPerhaps I exaggerate slightly, but it is no overstatement to suggest that you will find yourself being guided by proverbial angels and demons perched on opposite shoulders, or a whispering voice inside your head. If you harness this sense, sharpening it as if it were another tool in your kit and letting it guide or at least advise your decision making, you will transcend the rocky realm of random trial and error when faced with problems, and tend toward the right answers instinctively.\n\nThis gland can also empower your ability to assess your own work, becoming a judge before whom all your work is cross-examined. A good craftsperson regularly takes a step back from their work, and questions every facet of their product for its precise alignment with their core values of quality and sincerity, and even the very necessity of each component.\n\nThe wrapping\n\nBy now, you may be thinking that I take this kind of thing far too seriously, but to terrify you further, I haven\u2019t even shared the half of it. Hopefully, though, this gives you an idea of the kind of levels of professionalism and dedication that it should take to get you on your way to becoming a craftsperson. It\u2019s a level of accomplishment and ability toward which we all should strive, both for our personal fulfilment and the betterment of the products we use daily. I look forward to seeing your finely crafted work throughout 2012.", "year": "2011", "author": "Ben Bodien", "author_slug": "benbodien", "published": "2011-12-24T00:00:00+00:00", "url": "https://24ways.org/2011/crafting-the-front-end/", "topic": "process"}
{"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 <ul>. Many designs, however, do not cater to non-JavaScript versions of the website, and thus don\u2019t take in to account large multiple images. You could also simply hide all the other images in the list, apart from the first image. This method can waste bandwidth because the other images might be downloaded when they are never going to be seen.\n\nTaking this second concept \u2014 only showing one image \u2014 the only code you need to start your slideshow is an <img> tag. The other images can be loaded dynamically via either a per-page JavaScript array or via AJAX.\n\nThe slideshow concept is built upon the very versatile Cycle jQuery Plugin and is structured in to another reusable jQuery plugin. Below is the HTML and JavaScript snippet needed to run every different type of slideshow I have mentioned above.\n\n<img src=\"path/to/image.jpg\" alt=\"About the image\" title=\"\" height=\"250\" width=\"400\" class=\"slideshow\">\n<script type=\"text/javascript\">\n\tjQuery().ready(function($) {\n\t\t$('img.slideshow').slideShow({\n\t\t\timages: ['1.jpg', '2.jpg', '3.jpg']\n\t\t});\n\t});\n</script>\n\nSlideshow plugin\n\nIf you\u2019re not familiar with jQuery or how to write and author your own plugin there are plenty of articles to help you out.\n\njQuery has a chainable interface and this is something your plugin must implement. This is easy to achieve, so your plugin simply returns the collection it is using:\n\nreturn this.each(\n\tfunction () {}\n};\n\nLocal Variables\n\nTo keep the JavaScript clean and avoid any conflicts, you must set up any variables which are local to the plugin and should be used on each collection item. Defining all your variables at the top under one statement makes adding more and finding which variables are used easier. For other tips, conventions and improvements check out JSLint, the \u201cJavaScript Code Quality Tool\u201d.\n\nvar $$, $div, $images, $arrows, $pager,\n\tid, selector, path, o, options,\n\theight, width,\n\tlist = [], li = 0,\n\tparts = [], pi = 0,\n\tarrows = ['Previous', 'Next'];\n\nCache jQuery Objects\n\nIt is good practice to cache any calls made to jQuery. This reduces wasted DOM calls, can improve the speed of your JavaScript code and makes code more reusable.\n\nThe following code snippet caches the current selected DOM element as a jQuery object using the variable name $$. Secondly, the plugin makes its settings available to the Metadata plugin\u2021 which is best practice within jQuery plugins.\n\nFor each slideshow the plugin generates a <div> with a class of slideshow and a unique id. This is used to wrap the slideshow images, pagination and controls.\n\nThe base path which is used for all the images in the slideshow is calculated based on the existing image which appears on the page. For example, if the path to the image on the page was /img/flowers/1.jpg the plugin would use the path /img/flowers/ to load the other images.\n\n$$ = $(this);\no = $.metadata ? $.extend({}, settings, $$.metadata()) : settings;\nid = 'slideshow-' + (i++ + 1);\n$div = $('<div />').addClass('slideshow').attr('id', id);\nselector = '#' + id + ' ';\npath = $$.attr('src').replace(/[0-9]\\.jpg/g, '');\noptions = {};\nheight = $$.height();\nwidth = $$.width();\n\nNote: the plugin uses conventions such as folder structure and numeric filenames. These conventions help with the reusable aspect of plugins and best practices.\n\nBuild the Images\n\nThe cycle plugin uses a list of images to create the slideshow. Because we chose to start with one image we must now build the list programmatically. This is a case of looping through the images which were added via the plugin options, building the appropriate HTML and appending the resulting <ul> to the DOM.\n\n$.each(o.images, function () {\n\tlist[li++] = '<li>';\n\tlist[li++] = '<img src=\"' + path + this + '\" height=\"' + height + '\" width=\"' + width + '\">';\n\tlist[li++] = '</li>';\n});\n$images = $('<ul />').addClass('cycle-images');\n$images.append(list.join('')).appendTo($div);\n\nAlthough jQuery provides the append method it is much faster to create one really long string and append it to the DOM at the end.\n\nUpdate the Options\n\nHere are some of the options we\u2019re making available by simply adding classes to the <img>. You can change the slideshow effect from the default fade to the sliding effect. By adding the class of stopped the slideshow will not auto-play and must be controlled via pagination or previous and next links.\n\n// different effect\nif ($$.is('.slide')) {\n\toptions.fx = 'scrollHorz';\n}\n// don't move by default\nif ($$.is('.stopped')) {\n\toptions.timeout = 0;\n}\n\nIf you are using the same set of images throughout a website you may wish to start on a different image on each page or section. This can be easily achieved by simply adding the appropriate starting class to the <img>.\n\n// based on the class name on the image\nif ($$.is('[class*=start-]')) {\n\toptions.startingSlide = parseInt($$.attr('class').replace(/.*start-([0-9]+).*/g, \"$1\"), 10) - 1;\n}\n\nFor example:\n\n<img src=\"/img/slideshow/3.jpg\" alt=\"About the image\" title=\"\" height=\"250\" width=\"400\" class=\"slideshow start-3\">\n\nBy default, and without JavaScript, the third image in this slideshow is shown. When the JavaScript is applied to the page the slideshow must know to start from the correct place, this is why the start class is required.\n\nYou could capture the default image name and parse it to get the position, but only the default image needs to be numeric to work with this plugin (and could easily be changed in future). Therefore, this extra specifically defined option means the plugin is more tolerant.\n\nPrevious/Next Links\n\nA common feature of slideshows is previous and next links enabling the user to manually progress the images. The Cycle plugin supports this functionality, but you must generate the markup yourself. Most people add these directly in the HTML but normally only support their behaviour when JavaScript is enabled. This goes against progressive enhancement. To keep with the best practice progress enhancement method the previous/next links should be generated with JavaScript.\n\nThe follow snippet checks whether the slideshow requires the previous/next links, via the arrows class. It restricts the Cycle plugin to the specific slideshow using the selector we created at the top of the plugin. This means multiple slideshows can run on one page without conflicting each other.\n\nThe code creates a <ul> using the arrows array we defined at the top of the plugin. It also adds a class to the slideshow container, meaning you can style different combinations of options in your CSS.\n\n// create the arrows\nif ($$.is('.arrows') && list.length > 1) {\n\toptions.next = selector + '.next';\n\toptions.prev = selector + '.previous';\n\t$arrows = $('<ul />').addClass('cycle-arrows');\n\t$.each(arrows, function (i, val) {\n\t\tparts[pi++] = '<li class=\"' + val.toLowerCase() + '\">';\n\t\tparts[pi++] = '<a href=\"#' + val.toLowerCase() + '\">';\n\t\tparts[pi++] = '<span>' + val + '</span>';\n\t\tparts[pi++] = '</a>';\n\t\tparts[pi++] = '</li>';\n\t});\n\t$arrows.append(parts.join('')).appendTo($div);\n\t$div.addClass('has-cycle-arrows');\n}\n\nThe arrow array could be placed inside the plugin settings to allow for localisation.\n\nPagination\n\nThe Cycle plugin creates its own HTML for the pagination of the slideshow. All our plugin needs to do is create the list and selector to use. This snippet creates the pagination container and appends it to our specific slideshow container. It sets the Cycle plugin pager option, restricting it to the specific slideshow using the selector we created at the top of the plugin. Like the previous/next links, a class is added to the slideshow container allowing you to style the slideshow itself differently.\n\n// create the clickable pagination\nif ($$.is('.pagination') && list.length > 1) {\n\toptions.pager = selector + '.cycle-pagination';\n\t$pager = $('<ul />').addClass('cycle-pagination');\n\t$pager.appendTo($div);\n\t$div.addClass('has-cycle-pagination');\n}\n\nNote: the Cycle plugin creates a <ul> with anchors listed directly inside without the surrounding <li>. Unfortunately this is invalid markup but the code still works.\n\nDemos\n\nWell, that describes all the ins-and-outs of the plugin, but demos make it easier to understand! Viewing the source on the demo page shows some of the combinations you can create with a simple <img>, a few classes and some thought-out JavaScript.\n\nView the demos \u2192\n\nDecide on defaults\n\nThe slideshow plugin uses the exact same settings as the Cycle plugin, but some are explicitly set within the slideshow plugin when using the classes you have set.\n\nWhen deciding on what functionality is going to be controlled via this class method, be careful to choose your defaults wisely. If all slideshows should auto-play, don\u2019t make this an option \u2014 make the option to stop the auto-play. Similarly, if every slideshow should have previous/next functionality make this the default and expose the ability to remove them with a class such as \u201cno-pagination\u201d.\n\nIn the examples presented on this article I have used a class on each <img>. You can easily change this to anything you want and simply apply the plugin based on the jQuery selector required.\n\nGrab your images\n\nIf you are using AJAX to load in your images, you can speed up development by deciding on and keeping to a folder structure and naming convention. There are two methods: basing the image path based on the current URL; or based on the src of the image. The first allows a different slideshow on each page, but in many instances a site will have a couple of sets of images and therefore the second method is probably preferred.\n\nMetadata \u2021\n\nA method which allows you to directly modify settings in certain plugins, which also uses the classes from your HTML already exists. This is a jQuery plugin called Metadata. This method allows for finer control over the plugin settings themselves. Some people, however, may dislike the syntax and prefer using normal classes, like above which when sprinkled with a bit more JavaScript allows you to control what you need to control.\n\nThe takeaway\n\nHopefully you have understood not only what goes in to a basic jQuery plugin but also learnt a new and powerful idea which you can apply to other areas of your website.\n\nThe idea can also be applied to other common interfaces such as lightboxes or mapping services such as Google Maps \u2014 for example creating markers based on a list of places, each with different pin icons based the anchor class.", "year": "2009", "author": "Trevor Morris", "author_slug": "trevormorris", "published": "2009-12-06T00:00:00+00:00", "url": "https://24ways.org/2009/front-end-code-reusability-with-css-and-javascript/", "topic": "code"}
{"rowid": 117, "title": "The First Tool You Reach For", "contents": "Microsoft recently announced that Internet Explorer 8 will be released in the first half of 2009. Compared to the standards support of other major browsers, IE8 will not be especially great, but it will finally catch up with the state of the art in one specific area: support for CSS tables. This milestone has the potential to trigger an important change in the way you approach web design.\n\nTo show you just how big a difference CSS tables can make, think about how you might code a fluid, three-column layout from scratch. Just to make your life more difficult, give it one fixed-width column, with a background colour that differs from the rest of the page. Ready? Go!\n\nOkay, since you\u2019re the sort of discerning web designer who reads 24ways, I\u2019m going to assume you at least considered doing this without using HTML tables for the layout. If you\u2019re especially hardcore, I imagine you began thinking of CSS floats, negative margins, and faux columns. If you did, colour me impressed!\n\nNow admit it: you probably also gave an inward sigh about the time it would take to figure out the math on the negative margin overlaps, check for dropped floats in Internet Explorer and generally wrestle each of the major browsers into giving you what you want. If after all that you simply gave up and used HTML tables, I can\u2019t say I blame you.\n\nThere are plenty of professional web designers out there who still choose to use HTML tables as their main layout tool. Sure, they may know that users with screen readers get confused by inappropriate use of tables, but they have a job to do, and they want tools that will make that job easy, not difficult.\n\nNow let me show you how to do it with CSS tables. First, we have a div element for each of our columns, and we wrap them all in another two divs:\n\n<div class=\"container\">\n\t<div>\n\t\t<div id=\"menu\">\n\t\t\u22ee\n\t\t</div>\n\t\t<div id=\"content\">\n\t\t\u22ee\n\t\t</div>\n\t\t<div id=\"sidebar\">\n\t\t\u22ee\n\t\t</div>\n\t</div>\n</div>\n\nDon\u2019t sweat the \u201cdiv clutter\u201d in this code. Unlike tables, divs have no semantic meaning, and can therefore be used liberally (within reason) to provide hooks for the styles you want to apply to your page.\n\nUsing CSS, we can set the outer div to display as a table with collapsed borders (i.e. adjacent cells share a border) and a fixed layout (i.e. cell widths unaffected by their contents):\n\n.container {\n\tdisplay: table;\n\tborder-collapse: collapse;\n\ttable-layout: fixed;\n}\n\nWith another two rules, we set the middle div to display as a table row, and each of the inner divs to display as table cells:\n\n.container > div {\n\tdisplay: table-row;\n}\n.container > div > div {\n\tdisplay: table-cell;\n}\n\nFinally, we can set the widths of the cells (and of the table itself) directly:\n\n.container {\n\twidth: 100%;\n}\n#menu {\n\twidth: 200px;\n}\n#content {\n\twidth: auto;\n}\n#sidebar {\n\twidth: 25%;\n}\n\nAnd, just like that, we have a rock solid three-column layout, ready to be styled to your own taste, like in this example:\n\n\n\nThis example will render perfectly in reasonably up-to-date versions of Firefox, Safari and Opera, as well as the current beta release of Internet Explorer 8.\n\nCSS tables aren\u2019t only useful for multi-column page layout; they can come in handy in most any situation that calls for elements to be displayed side-by-side on the page. Consider this simple login form layout:\n\n\n\nThe incantation required to achieve this layout using CSS floats may be old hat to you by now, but try to teach it to a beginner, and watch his eyes widen in horror at the hoops you have to jump through (not to mention the assumptions you have to build into your design about the length of the form labels).\n\nHere\u2019s how to do it with CSS tables:\n\n<form action=\"/login\" method=\"post\">\n\t<div>\n\t\t<div>\n\t\t\t<label for=\"username\">Username:</label>\n\t\t\t<span class=\"input\"><input type=\"text\" name=\"username\" id=\"username\"/></span>\n\t\t</div>\n\t\t<div>\n\t\t\t<label for=\"userpass\">Password:</label>\n\t\t\t<span class=\"input\"><input type=\"password\" name=\"userpass\" id=\"userpass\"/></span>\n\t\t</div>\n\t\t<div class=\"submit\">\n\t\t\t<label for=\"login\"></label>\n\t\t\t<span class=\"input\"><input type=\"submit\" name=\"login\" id=\"login\" value=\"Login\"/></span>\n\t\t</div>\n\t</div>\n</form>\n\nThis time, we\u2019re using a mixture of divs and spans as semantically transparent styling hooks. Let\u2019s look at the CSS code.\n\nFirst, we set up the outer div to display as a table, the inner divs to display as table rows, and the labels and spans as table cells (with right-aligned text):\n\nform > div {\n\tdisplay: table;\n}\nform > div > div {\n\tdisplay: table-row;\n}\nform label,\nform span {\n\tdisplay: table-cell;\n\ttext-align: right;\n}\n\nWe want the first column of the table to be wide enough to accommodate our labels, but no wider. With CSS float techniques, we had to guess at what that width was likely to be, and adjust it whenever we changed our form labels. With CSS tables, we can simply set the width of the first column to something very small (1em), and then use the white-space property to force the column to the required width:\n\nform label {\n\twhite-space: nowrap;\n\twidth: 1em;\n}\n\nTo polish off the layout, we\u2019ll make our text and password fields occupy the full width of the table cells that contain them:\n\ninput[type=text],\ninput[type=password] {\n\twidth: 100%;\n}\n\nThe rest is margins, padding and borders to get the desired look. Check out the finished example.\n\nAs the first tool you reach for when approaching any layout task, CSS tables make a lot more sense to your average designer than the cryptic incantations called for by CSS floats. When IE8 is released and all major browsers support CSS tables, we can begin to gradually deploy CSS table-based layouts on sites that are more and more mainstream.\n\nIn our new book, Everything You Know About CSS Is Wrong!, Rachel Andrew and I explore in much greater detail how CSS tables work as a page layout tool in the real world. CSS tables have their quirks just like floats do, but they don\u2019t tend to affect common layout tasks, and the workarounds tend to be less fiddly too.

{"rowid": 168, "title": "Unobtrusively Mapping Microformats with jQuery", "contents": "Microformats are everywhere. You can\u2019t shake an electronic stick these days without accidentally poking a microformat-enabled site, and many developers use microformats as a matter of course. And why not? After all, why invent your own class names when you can re-use pre-defined ones that give your site extra functionality for free?\n\nNevertheless, while it\u2019s good to know that users of tools such as Tails and Operator will derive added value from your shiny semantics, it\u2019s nice to be able to reuse that effort in your own code.\n\nWe\u2019re going to build a map of some of my favourite restaurants in Brighton. Fitting with the principles of unobtrusive JavaScript, we\u2019ll start with a semantically marked up list of restaurants, then use JavaScript to add the map, look up the restaurant locations and plot them as markers.\n\nWe\u2019ll be using a couple of powerful tools. The first is jQuery, a JavaScript library that is ideally suited for unobtrusive scripting. jQuery allows us to manipulate elements on the page based on their CSS selector, which makes it easy to extract information from microformats.\n\nThe second is Mapstraction, introduced here by Andrew Turner a few days ago. We\u2019ll be using Google Maps in the background, but Mapstraction makes it easy to change to a different provider if we want to later.\n\nGetting Started\n\nWe\u2019ll start off with a simple collection of microformatted restaurant details, representing my seven favourite restaurants in Brighton. The full, unstyled list can be seen in restaurants-plain.html. Each restaurant listing looks like this:\n\n<li class=\"vcard\">\n\t<h3><a class=\"fn org url\" href=\"http://www.riddleandfinns.co.uk/\">Riddle & Finns</a></h3>\n\t<div class=\"adr\">\n\t\t<p class=\"street-address\">12b Meeting House Lane</p>\n\t\t<p><span class=\"locality\">Brighton</span>, <abbr class=\"country-name\" title=\"United Kingdom\">UK</abbr></p>\n\t\t<p class=\"postal-code\">BN1 1HB</p>\n\t</div>\n\t<p>Telephone: <span class=\"tel\">+44 (0)1273 323 008</span></p>\n\t<p>E-mail: <a href=\"mailto:info@riddleandfinns.co.uk\" class=\"email\">info@riddleandfinns.co.uk</a></p>\n</li>\n\nSince we\u2019re dealing with a list of restaurants, each hCard is marked up inside a list item. Each restaurant is an organisation; we signify this by placing the classes fn and org on the element surrounding the restaurant\u2019s name (according to the hCard spec, setting both fn and org to the same value signifies that the hCard represents an organisation rather than a person).\n\nThe address information itself is contained within a div of class adr. Note that the HTML <address> element is not suitable here for two reasons: firstly, it is intended to mark up contact details for the current document rather than generic addresses; secondly, address is an inline element and as such cannot contain the paragraphs elements used here for the address information.\n\nA nice thing about microformats is that they provide us with automatic hooks for our styling. For the moment we\u2019ll just tidy up the whitespace a bit; for more advanced style tips consult John Allsop\u2019s guide from 24 ways 2006.\n\n.vcard p {\n\tmargin: 0;\n}\n.adr {\n\tmargin-bottom: 0.5em;\n}\n\nTo plot the restaurants on a map we\u2019ll need latitude and longitude for each one. We can find this out from their address using geocoding. Most mapping APIs include support for geocoding, which means we can pass the API an address and get back a latitude/longitude point. Mapstraction provides an abstraction layer around these APIs which can be included using the following script tag:\n\n<script type=\"text/javascript\" src=\"http://mapstraction.com/src/mapstraction-geocode.js\"></script>\n\nWhile we\u2019re at it, let\u2019s pull in the other external scripts we\u2019ll be using:\n\n<script type=\"text/javascript\" src=\"jquery-1.2.1.js\"></script>\n<script src=\"http://maps.google.com/maps?file=api&v=2&key=YOUR_KEY\" type=\"text/javascript\"></script>\n<script type=\"text/javascript\" src=\"http://mapstraction.com/src/mapstraction.js\"></script>\n<script type=\"text/javascript\" src=\"http://mapstraction.com/src/mapstraction-geocode.js\"></script>\n\nThat\u2019s everything set up: let\u2019s write some JavaScript!\n\nIn jQuery, almost every operation starts with a call to the jQuery function. The function simulates method overloading to behave in different ways depending on the arguments passed to it. When writing unobtrusive JavaScript it\u2019s important to set up code to execute when the page has loaded to the point that the DOM is available to be manipulated. To do this with jQuery, pass a callback function to the jQuery function itself:\n\njQuery(function() {\n\t// This code will be executed when the DOM is ready\n});\n\nInitialising the map\n\nThe first thing we need to do is initialise our map. Mapstraction needs a div with an explicit width, height and ID to show it where to put the map. Our document doesn\u2019t currently include this markup, but we can insert it with a single line of jQuery code:\n\njQuery(function() {\n\t// First create a div to host the map\n\tvar themap = jQuery('<div id=\"themap\"></div>').css({\n\t\t'width': '90%',\n\t\t'height': '400px'\n\t}).insertBefore('ul.restaurants');\n});\n\nWhile this is technically just a single line of JavaScript (with line-breaks added for readability) it\u2019s actually doing quite a lot of work. Let\u2019s break it down in to steps:\n\nvar themap = jQuery('<div id=\"themap\"></div>')\n\nHere\u2019s jQuery\u2019s method overloading in action: if you pass it a string that starts with a < it assumes that you wish to create a new HTML element. This provides us with a handy shortcut for the more verbose DOM equivalent:\n\nvar themap = document.createElement('div');\nthemap.id = 'themap';\n\nNext we want to apply some CSS rules to the element. jQuery supports chaining, which means we can continue to call methods on the object returned by jQuery or any of its methods:\n\nvar themap = jQuery('<div id=\"themap\"></div>').css({\n\t'width': '90%',\n\t'height': '400px'\n})\n\nFinally, we need to insert our new HTML element in to the page. jQuery provides a number of methods for element insertion, but in this case we want to position it directly before the <ul> we are using to contain our restaurants. jQuery\u2019s insertBefore() method takes a CSS selector indicating an element already on the page and places the current jQuery selection directly before that element in the DOM.\n\nvar themap = jQuery('<div id=\"themap\"></div>').css({\n\t'width': '90%',\n\t'height': '400px'\n}).insertBefore('ul.restaurants');\n\nFinally, we need to initialise the map itself using Mapstraction. The Mapstraction constructor takes two arguments: the first is the ID of the element used to position the map; the second is the mapping provider to use (in this case google ):\n\n// Initialise the map\nvar mapstraction = new Mapstraction('themap','google');\n\nWe want the map to appear centred on Brighton, so we\u2019ll need to know the correct co-ordinates. We can use www.getlatlon.com to find both the co-ordinates and the initial map zoom level.\n\n// Show map centred on Brighton\nmapstraction.setCenterAndZoom(\n\tnew LatLonPoint(50.82423734980143, -0.14007568359375),\n\t15 // Zoom level appropriate for Brighton city centre\n);\n\nWe also want controls on the map to allow the user to zoom in and out and toggle between map and satellite view.\n\nmapstraction.addControls({\n\tzoom: 'large',\n\tmap_type: true\n});\n\nAdding the markers\n\nIt\u2019s finally time to parse some microformats. Since we\u2019re using hCard, the information we want is wrapped in elements with the class vcard. We can use jQuery\u2019s CSS selector support to find them:\n\nvar vcards = jQuery('.vcard');\n\nNow that we\u2019ve found them, we need to create a marker for each one in turn. Rather than using a regular JavaScript for loop, we can instead use jQuery\u2019s each() method to execute a function against each of the hCards.\n\njQuery('.vcard').each(function() {\n\t// Do something with the hCard\n});\n\nWithin the callback function, this is set to the current DOM element (in our case, the list item). If we want to call the magic jQuery methods on it we\u2019ll need to wrap it in another call to jQuery:\n\njQuery('.vcard').each(function() {\n\tvar hcard = jQuery(this);\n});\n\nThe Google maps geocoder seems to work best if you pass it the street address and a postcode. We can extract these using CSS selectors: this time, we\u2019ll use jQuery\u2019s find() method which searches within the current jQuery selection:\n\nvar streetaddress = hcard.find('.street-address').text();\nvar postcode = hcard.find('.postal-code').text();\n\nThe text() method extracts the text contents of the selected node, minus any HTML markup.\n\nWe\u2019ve got the address; now we need to geocode it. Mapstraction\u2019s geocoding API requires us to first construct a MapstractionGeocoder, then use the geocode() method to pass it an address. Here\u2019s the code outline:\n\nvar geocoder = new MapstractionGeocoder(onComplete, 'google');\ngeocoder.geocode({'address': 'the address goes here');\n\nThe onComplete function is executed when the geocoding operation has been completed, and will be passed an object with the resulting point on the map. We just want to create a marker for the point:\n\nvar geocoder = new MapstractionGeocoder(function(result) {\n\tvar marker = new Marker(result.point);\n\tmapstraction.addMarker(marker);\n}, 'google');   \n\nFor our purposes, joining the street address and postcode with a comma to create the address should suffice:\n\ngeocoder.geocode({'address': streetaddress + ', ' + postcode});   \n\nThere\u2019s one last step: when the marker is clicked, we want to display details of the restaurant. We can do this with an info bubble, which can be configured by passing in a string of HTML. We\u2019ll construct that HTML using jQuery\u2019s html() method on our hcard object, which extracts the HTML contained within that DOM node as a string.\n\nvar marker = new Marker(result.point);\nmarker.setInfoBubble(\n\t'<div class=\"bubble\">' + hcard.html() + '</div>'\n);\nmapstraction.addMarker(marker);\n\nWe\u2019ve wrapped the bubble in a div with class bubble to make it easier to style. Google Maps can behave strangely if you don\u2019t provide an explicit width for your info bubbles, so we\u2019ll add that to our CSS now:\n\n.bubble {\n\twidth: 300px;\n}\n\nThat\u2019s everything we need: let\u2019s combine our code together:\n\njQuery(function() {\n\t// First create a div to host the map\n\tvar themap = jQuery('<div id=\"themap\"></div>').css({\n\t\t'width': '90%',\n\t\t'height': '400px'\n\t}).insertBefore('ul.restaurants');\n\t// Now initialise the map\n\tvar mapstraction = new Mapstraction('themap','google');\n\tmapstraction.addControls({\n\t\tzoom: 'large',\n\t\tmap_type: true\n\t});\n\t// Show map centred on Brighton\n\tmapstraction.setCenterAndZoom(\n\t\tnew LatLonPoint(50.82423734980143, -0.14007568359375),\n\t\t15 // Zoom level appropriate for Brighton city centre\n\t);\n\t// Geocode each hcard and add a marker\n\tjQuery('.vcard').each(function() {\n\t\tvar hcard = jQuery(this);\n\t\tvar streetaddress = hcard.find('.street-address').text();\n\t\tvar postcode = hcard.find('.postal-code').text();\n\t\tvar geocoder = new MapstractionGeocoder(function(result) {\n\t\t\tvar marker = new Marker(result.point);\n\t\t\tmarker.setInfoBubble(\n\t\t\t\t'<div class=\"bubble\">' + hcard.html() + '</div>'\n\t\t\t);\n\t\t\tmapstraction.addMarker(marker);\n\t\t}, 'google');\t \n\t\tgeocoder.geocode({'address': streetaddress + ', ' + postcode});\n\t});\n});\n\nHere\u2019s the finished code.\n\nThere\u2019s one last shortcut we can add: jQuery provides the $ symbol as an alias for jQuery. We could just go through our code and replace every call to jQuery() with a call to $(), but this would cause incompatibilities if we ever attempted to use our script on a page that also includes the Prototype library. A more robust approach is to start our code with the following:\n\njQuery(function($) {\n\t// Within this function, $ now refers to jQuery\n\t// ...\n});\n\njQuery cleverly passes itself as the first argument to any function registered to the DOM ready event, which means we can assign a local $ variable shortcut without affecting the $ symbol in the global scope. This makes it easy to use jQuery with other libraries.\n\nLimitations of Geocoding\n\nYou may have noticed a discrepancy creep in to the last example: whereas my original list included seven restaurants, the geocoding example only shows five. This is because the Google Maps geocoder incorporates a rate limit: more than five lookups in a second and it starts returning error messages instead of regular results.\n\nIn addition to this problem, geocoding itself is an inexact science: while UK postcodes generally get you down to the correct street, figuring out the exact point on the street from the provided address usually isn\u2019t too accurate (although Google do a pretty good job).\n\nFinally, there\u2019s the performance overhead. We\u2019re making five geocoding requests to Google for every page served, even though the restaurants themselves aren\u2019t likely to change location any time soon. Surely there\u2019s a better way of doing this?\n\nMicroformats to the rescue (again)! The geo microformat suggests simple classes for including latitude and longitude information in a page. We can add specific points for each restaurant using the following markup:\n\n<li class=\"vcard\">\n\t<h3 class=\"fn org\">E-Kagen</h3>\n\t<div class=\"adr\">\n\t\t<p class=\"street-address\">22-23 Sydney Street</p>\n\t\t<p><span class=\"locality\">Brighton</span>, <abbr class=\"country-name\" title=\"United Kingdom\">UK</abbr></p>\n\t\t<p class=\"postal-code\">BN1 4EN</p>\n\t</div>\n\t<p>Telephone: <span class=\"tel\">+44 (0)1273 687 068</span></p>\n\t<p class=\"geo\">Lat/Lon: \n\t\t<span class=\"latitude\">50.827917</span>, \n\t\t<span class=\"longitude\">-0.137764</span>\n\t</p>\n</li>\n\nAs before, I used www.getlatlon.com to find the exact locations \u2013 I find satellite view is particularly useful for locating individual buildings.\n\nLatitudes and longitudes are great for machines but not so useful for human beings. We could hide them entirely with display: none, but I prefer to merely de-emphasise them (someone might want them for their GPS unit):\n\n.vcard .geo {\n\tmargin-top: 0.5em;\n\tfont-size: 0.85em;\n\tcolor: #ccc;\n}\n\nIt\u2019s probably a good idea to hide them completely when they\u2019re displayed inside an info bubble:\n\n.bubble .geo {\n\tdisplay: none;\n}\n\nWe can extract the co-ordinates in the same way we extracted the address. Since we\u2019re no longer geocoding anything our code becomes a lot simpler:\n\n$('.vcard').each(function() {\n\tvar hcard = $(this);\n\tvar latitude = hcard.find('.geo .latitude').text();\n\tvar longitude = hcard.find('.geo .longitude').text();\n\tvar marker = new Marker(new LatLonPoint(latitude, longitude));\n\tmarker.setInfoBubble(\n\t\t'<div class=\"bubble\">' + hcard.html() + '</div>'\n\t);\n\tmapstraction.addMarker(marker);\n});\n\nAnd here\u2019s the finished geo example.\n\nFurther reading\n\nWe\u2019ve only scratched the surface of what\u2019s possible with microformats, jQuery (or just regular JavaScript) and a bit of imagination. If this example has piqued your interest, the following links should give you some more food for thought.\n\n\n\tThe hCard specification\n\tNotes on parsing hCards\n\tjQuery for JavaScript programmers \u2013 my extended tutorial on jQuery.\n\tDann Webb\u2019s Sumo \u2013 a full JavaScript library for parsing microformats, based around some clever metaprogramming techniques.\n\tJeremy Keith\u2019s Adactio Austin \u2013 the first place I saw using microformats to unobtrusively plot locations on a map.

{"rowid": 57, "title": "Cooking Up Effective Technical Writing", "contents": "Merry Christmas! May your preparations for this festive season of gluttony be shaping up beautifully. By the time you read this I hope you will have ordered your turkey, eaten twice your weight in Roses/Quality Street (let\u2019s not get into that argument), and your Christmas cake has been baked and is now quietly absorbing regular doses of alcohol.\nSome of you may be reading this and scoffing Of course! I\u2019ve also made three batches of mince pies, a seasonal chutney and enough gingerbread men to feed the whole street! while others may be laughing Bake? Oh no, I can\u2019t cook to save my life.\nFor beginners, recipes are the step-by-step instructions that hand-hold us through the cooking process, but even as a seasoned expert you\u2019re likely to refer to a recipe at some point. Recipes tell us what we need, what to do with it, in what order, and what the outcome will be. It\u2019s the documentation behind our ideas, and allows us to take the blueprint for a tasty morsel and to share it with others so they can recreate it. In fact, this is a little like the open source documentation and tutorials that we put out there, similarly aiming to guide other developers through our creations.\nThe \u2018just\u2019ification of documentation\nLately it feels like we\u2019re starting to consider the importance of our words, and the impact they can have on others. Brad Frost warned us of the dangers of \u201cJust\u201d when it comes to offering up solutions to queries:\n\n\u201cJust use this software/platform/toolkit/methodology\u2026\u201d\n\u201cJust\u201d makes me feel like an idiot. \u201cJust\u201d presumes I come from a specific background, studied certain courses in university, am fluent in certain technologies, and have read all the right books, articles, and resources. \u201cJust\u201d is a dangerous word.\n\u201cJust\u201d by Brad Frost\n\nI can really empathise with these sentiments. My relationship with code started out as many good web tales do, with good old HTML, CSS and JavaScript. University years involved some time with Perl, PHP, Java and C. In my first job I worked primarily with ColdFusion, a bit of ActionScript, some classic\u00a0 ASP and pinch of Java. I\u2019d do a bit of PHP outside work every now and again. .NET came in, but we never really got on, and eventually I started learning some Ruby, Python and Node. It was a broad set of learnings, and I enjoyed the similarities and differences that came with new languages. I don\u2019t develop day in, day out any more, and my interests and work have evolved over the years, away from full-time development and more into architecture and strategy. But I still make things, and I still enjoy learning.\nI have often found myself bemoaning the lack of tutorials or courses that cater for the middle level \u2013 someone who may be learning a new language, but who has enough programming experience under their belt to not need to revise the concepts of how loops or objects work, and is perfectly adept at googling the syntax for getting a substring. I don\u2019t want snippets out of context; I want an understanding of architectural principles, of the strengths and weaknesses, of the type of applications that work well with the language.\nI\u2019m caught in the place between snoozing off when \u2018Using the Instagram API with Ruby\u2019 hand-holds me through what REST is, and feeling like I\u2019m stupid and need to go back to dev school when I can\u2019t get my environment and dependencies set up, let alone work out how I\u2019m meant to get any code to run.\nIt\u2019s seems I\u2019m not alone with this \u2013 Erin McKean seems to have been here too:\n\n\u201cSome tutorials (especially coding tutorials) like to begin things in media res. Great for a sense of dramatic action, bad for getting to \u201cStep 1\u201d without tears. It can be really discouraging to fire up a fresh terminal window only to be confronted by error message after error message because there were obligatory steps 0.1.0 through 0.9.9 that you didn\u2019t even know about.\u201d\n\u201cTips for Learning What You Don\u2019t Know You Don\u2019t Know\u201d by Erin McKean\n\nI\u2019m sure you\u2019ve been here too. Many tutorials suffer badly from the fabled \u2018how to draw an owl\u2019-itis.\n\nIt\u2019s the kind of feeling you can easily get when sifting through recipes as well as with code. Far from being the simple instructions that let us just follow along, they too can be a minefield. Fall in too low and you may be skipping over an explanation of what simmering is, or set your sights too high and you may get stuck at the point where you\u2019re trying to sous vide a steak using your bathtub and a Ziploc bag.\nDon\u2019t be a turkey, use your loaf!\nMy mum is a great cook in my eyes (aren\u2019t all mums?). I love her handcrafted collection of gathered recipes from over the years, including the one below, which is a great example of how something may make complete sense to the writer, but could be impermeable to a reader.\n\nDepending on your level of baking knowledge, you may ask: What\u2019s SR flour? What\u2019s a tsp? Should I use salted or unsalted butter? Do I use sticks of cinnamon or ground? Why is chopped chocolate better? How do I cream things? How big should the balls be? How well is \u201cwell spaced\u201d? How much leeway do I have for \u201c(ish!!)\u201d? Does the \u201c20\u201d on the other cookie note mean I\u2019ll end up with twenty? At any point, making a wrong call could lead to rubbish cookies, and lead to someone heading down the path of an I can\u2019t cook mentality.\nYou may be able to cook (or follow recipes), but you may not understand the local terms for ingredients, may not be able to acquire something and need to know what kind of substitutes you can use, or may need to actually do some prep before you jump into the main bit.\nHowever, if we look at good examples of recipes, I think there\u2019s a lot we can apply when it comes to technical writing on the web. I\u2019ve written before about the benefit of breaking documentation into small, reusable parts, and this will help us, but we can also take it a bit further. Here are my five top tips for better technical writing.\n1. Structure and standardise your information\nThink of the structure of a recipe. We very often have some common elements and they usually follow roughly the same format. We have standards and conventions that allow us to understand very quickly what a recipe is and how it should be used.\u00a0\n\nGreat recipes help their chefs know what they need to get ready in advance, both in terms of buying ingredients and putting together their kit. They then talk through the process, using appropriate language, and without making assumptions that the person can fill in any gaps for themselves; they explain why things are done the way they are. The best recipes may also suggest how you can take what you\u2019ve done and put your own spin on it. For instance, a good recipe for the simple act of boiling an egg will explain cooking time in relation to your preference for yolk gooiness. There are also different flavour combinations to try, accompaniments, or presentation suggestions.\u00a0\nBy breaking down your technical writing into similar sections, you can help your audience understand the elements they\u2019ll be working with, what they need to do once they have these, and how they can move on from your self-contained illustration.\nTitle\n      \n        Ensure your title is suitably descriptive and representative of the result. Getting Started with Python perhaps isn\u2019t as helpful as Learn Python: General Syntax and Basics.\n      \n    Result\n      \n        Many recipes include a couple of lines as an overview of what you\u2019ll end up with, and many include a photo of the finished dish. With our technical writing we can do the same:\n        In this tutorial we\u2019re going to learn how to set up our development environment, and we\u2019ll then undertake some exercises to explore the general syntax, finishing by building a mini calculator.\n      \n    Ingredients\n      \n        What are the components we\u2019ll be working with, whether in terms of versions, environment, languages or the software packages and libraries you\u2019ll need along the way? Listing these up front gives the reader a great summary of the things they\u2019ll be using, and any gotchas.\n        Being able to provide a small amount of supporting information will also help less experienced users. Ideally, explain briefly what things are and why we\u2019re using it.\n      \n    Prep\n      \n        As we heard from Erin above, not fully understanding the prep needed can be a huge source of frustration. Attempting to run a code snippet without context will often lead to failure when the prerequisites and process aren\u2019t clear. Be sure to include information around any environment set-up, installation or config you\u2019ll need to have done before you start.\nStu Robson\u2019s Simple Sass documentation aims to do this before getting into specifics, although ideally this would also include setting up Sass itself.\n      \n    Instructions\n      \nThe body of the tutorial itself is the whole point of our writing. The next four tips will hopefully make your tutorial much more successful.\n      \n    Variations\n      \n        Like our ingredients section, as important as explaining why we\u2019re using something in this context is, it\u2019s also great to explain alternatives that could be used instead, and the impact of doing so.\n        Perhaps go a step further, explaining ways that people can change what you have done in your tutorial/readme for use in different situations, or to provide further reading around next steps. What happens if they want to change your static array of demo data to use JSON, for instance? By giving some thought to follow-up questions, you can better support your readers.\n        While not in a separate section, the source code for GreenSock\u2019s GSAP JS basics explains:\n        We\u2019ll use a window.onload for simplicity, but typically it is best to use either jQuery\u2019s $(document).ready() or $(window).load() or cross-browser event listeners so that you\u2019re not limited to one.\n        Keep in mind to both:\n        Explain what variations are possible.\n          Explain why certain options may be more desirable than others in different situations.\n        \n    \n2. Small, reusable components\nReusable components are for life, not just for Christmas, and they\u2019re certainly not just for development. If you start to apply the structure above to your writing, you\u2019re probably going to keep coming across the same elements: Do I really have to explain how to install Sass and Node.js again, Sally? The danger with more clarity is that our writing becomes bloated and overly convoluted for advanced readers, those who don\u2019t need to be told how to beat an egg for the hundredth time.\u00a0\nInstead, by making our writing reusable and modular, and by creating smaller, central resources, we can provide context and extra detail where needed without diluting our core message. These could be references we create, or those already created well by others.\n\nThis recipe for katsudon makes use of this concept. Rather than explaining how to make tonkatsu or dashi stock, these each have their own page. Once familiar, more advanced readers will likely skip over the instructions for the component parts.\n\n3. Provide context to aid accessibility\nHere I\u2019m talking about accessibility in the broadest sense. Small, isolated snippets can be frustrating to those who don\u2019t fully understand the wider context of how our examples work.\nShowing an exciting standalone JavaScript function is great, but giving someone the full picture of how and when this is called, and how it should be included in relation to other HTML and CSS is even better. Giving your readers the ability to view a big picture version, and ideally the ability to download a full version of the source, will help to reduce some of the frustrations of trying to get your component to work in their set-up.\u00a0\n4. Be your own tech editor\nA good editor can be invaluable to your work, and wherever possible I\u2019d recommend that you try to get a neutral party to read over your writing. This may not always be possible, though, and you may need to rely on yourself to cast a critical eye over your work.\nThere are many tips out there around general editing, including printing out your work onto paper, or changing the font size: both will force your eyes to review it in a new light. Beyond this, I\u2019d like to encourage you to think about the following:\n\nExplain what things are. For example, instead of referencing Grunt, in the first instance perhaps reference \u201cGrunt (a JavaScript task runner that minimises repetitive activities through automation).\u201d\nExplain how you get things, even if this is a link to official installers and documentation. Don\u2019t leave your readers having to search.\nWhy are you using this approach/technology over other options?\nWhat happens if I use something else? What depends on this?\nAvoid exclusionary lingo or acronyms.\n\nAirbnb\u2019s JavaScript Style Guide includes useful pointers around their reasoning:\n\nUse computed property names when creating objects with dynamic property names.\nWhy? They allow you to define all the properties of an object in one place.\n\nThe language we use often makes assumptions, as we saw with \u201cjust\u201d. An article titled \u201cES6 for Beginners\u201d is hugely ambiguous: is this truly for beginner coders, or actually for people who have a good pre-existing understanding of JavaScript but are new to these features? Review your writing with different types of readers in mind. How might you confuse or mislead them? How can you better answer their questions?\nThis doesn\u2019t necessarily mean supporting everyone \u2013 your audience may need to have advanced skills \u2013 but even if you\u2019re providing low-level, deep-dive, reference material, trying not to make assumptions or take shortcuts will hopefully lead to better, clearer writing.\n5. A picture is worth a thousand words\u2026\n\u2026or even better: use a thousand pictures, stitched together into a quick video or animated GIF. People learn in different ways. Just as recipes often provide visual references or a video to work along with, providing your technical information with alternative demonstrations can really help get your point across. Your audience will be able to see exactly what you\u2019re doing, what they should expect as interaction responses, and what the process looks like at different points.\nThere are many, many options for recording your screen, including QuickTime Player on Mac OS X (File \u2192 New Screen Recording), GifGrabber, or Giffing Tool on Windows.\nPaul Swain, a UX designer, uses GIFs to provide additional context within his documentation, improving communication:\n\n\u201cMy colleagues (from across the organisation) love animated GIFs. Any time an interaction is referenced, it\u2019s accompanied by a GIF and a shared understanding of what\u2019s being designed. The humble GIF is worth so much more than a thousand words; and it\u2019s great for cats.\u201d\nPaul Swain\n\n\nNext time you\u2019re cooking up some instructions for readers, think back to what we can learn from recipes to help make your writing as accessible as possible. Use structure, provide reusable bitesize morsels, give some context, edit wisely, and don\u2019t scrimp on the GIFs. And above all, have a great Christmas!", "year": "2015", "author": "Sally Jenkinson", "author_slug": "sallyjenkinson", "published": "2015-12-18T00:00:00+00:00", "url": "https://24ways.org/2015/cooking-up-effective-technical-writing/", "topic": "content"}
{"rowid": 275, "title": "Context First: Web Strategy in Four Handy Ws", "contents": "Many, many years ago, before web design became my proper job, I trained and worked as a journalist. I studied publishing in London and spent three fun years learning how to take a few little nuggets of information and turn them into a story. I learned a bunch of stuff that has all been a huge help to my design career. Flatplanning, layout, typographic theory. All of these disciplines have since translated really well to web design, but without doubt the most useful thing I learned was how to ask difficult questions.\n\nPretty much from day one of journalism school they hammer into you the importance of the Five Ws. Five disarmingly simple lines of enquiry that eloquently manage to provide the meat of any decent story. And with alliteration thrown in too. For a young journo, it\u2019s almost too good to be true.\n\nWho? What? Where? When? Why? It seems so obvious to almost be trite but, fundamentally, any story that manages to answer those questions for the reader is doing a pretty good job. You\u2019ll probably have noticed feeling underwhelmed by certain news pieces in the past \u2013 disappointed, like something was missing. Some irritating oversight that really lets the story down. No doubt it was one of the Ws \u2013 those innocuous little suckers are generally only noticeable by their absence, but they sure get missed when they\u2019re not there. \n\nQuestion everything\n\nI\u2019ve always been curious. An inveterate tinkerer with things and asker of dopey questions, often to the point of abject annoyance for anyone unfortunate enough to have ended up in my line of fire. So, naturally, the Five Ws started drifting into other areas of my life. I\u2019d scrutinize everything, trying to justify or explain my rationale using these Ws, but I\u2019d also find myself ripping apart the stuff that clearly couldn\u2019t justify itself against the same criteria.\n\nSo when I started working as a designer I applied the same logic and, sure enough, the Ws pretty much mapped to the exact same needs we had for gathering requirements at the start of a project. It seemed so obvious, such a simple way to establish the purpose of a product. What was it for? Why we were making it? And, of course, who were we making it for? It forced clients to stop and think, when really what they wanted was to get going and see something shiny. Sometimes that was a tricky conversation to have, but it\u2019s no coincidence that those who got it also understood the value of strategy and went on to have good solid products, while those that didn\u2019t often ended up with arrogantly insular and very shiny but ultimately unsatisfying and expendable products. Empty vessels make the most noise and all that\u2026\n\nContent first\n\nI was both surprised and pleased when the whole content first idea started to rear its head a couple of years back. Pleased, because without doubt it\u2019s absolutely the right way to work. And surprised, because personally it\u2019s always been the way I\u2019ve done it \u2013 I wasn\u2019t aware there was even an alternative way. Content in some form or another is the whole reason we were making the things we were making. I can\u2019t even imagine how you\u2019d start figuring out what a site needs to do, how it should be structured, or how it should look without a really good idea of what that content might be. It baffles me still that this was somehow news to a lot of people. What on earth were they doing? Design without purpose is just folly, surely?\n\nIt\u2019s great to see the idea gaining momentum but, having watched it unfold, it occurred to me recently that although it\u2019s fantastic to see a tangible shift in thinking \u2013 away from those bleak times, where making things up was somehow deemed an appropriate way to do things \u2013 there\u2019s now a new bad guy in town.\n\nWith any buzzword solution of the moment, there\u2019s always a catch, and it seems like some have taken the content first approach a little too literally. By which I mean, it\u2019s literally the first thing they do. The project starts, there\u2019s a very cursory nod towards gathering requirements, and off they go, cranking content. Writing copy, making video, commissioning illustrations.\n\nAll that\u2019s happened is that the \u2018making stuff up\u2019 part has shifted along the line, away from layout and UI, back to the content. \n\nStarting is too easy\n\nI can\u2019t remember where I first heard that phrase, but it\u2019s a great sentiment which applies to so much of what we do on the web. The medium is so accessible and to an extent disposable; throwing things together quickly carries far less burden than in any other industry. We\u2019re used to tweaking as we go, changing bits, iterating things into shape. The ubiquitous beta tag has become the ultimate caveat, and has made the unfinished and unpolished acceptable. Of course, that can work brilliantly in some circumstances. Occasionally, a product offers such a paradigm shift it\u2019s beyond the level of deep planning and prelaunch finessing we\u2019d ideally like. But, in the main, for most client sites we work on, there really is no excuse not to do things properly. To ask the tricky questions, to challenge preconceptions and really understand the Ws behind the products we\u2019re making before we even start. \n\nThe four Ws\n\nFor product definition, only four of the five Ws really apply, although there\u2019s a lot of discussion around the idea of when being an influencing factor. For example, the context of a user\u2019s engagement with your product is something you can make a call on depending on the specifics of the project.\n\nSo, here\u2019s my take on the four essential Ws. I\u2019ll point out here that, of course, these are not intended to be autocratic dictums. Your needs may differ, your clients\u2019 needs may differ, but these four starting points will get you pretty close to where you need to be.\n\nWho \n\nIt\u2019s surprising just how many projects start without a real understanding of the intended audience. Many clients think they have an idea, but without really knowing \u2013 it\u2019s presumptive at best, and we all know what presumption is the mother of, right? Of course, we can\u2019t know our audiences in the same way a small shop owner might know their customers. But we can at least strive to find out what type of people are likely to be using the product. I\u2019m not talking about deep user research. That should come later.\n\nThese are the absolute basics. What\u2019s the context for their visit? How informed are they? What\u2019s their level of comprehension? Are they able to self-identify and relate to categories you have created? I could go on, and it changes on a per-project basis. You\u2019ll only find this out by speaking to them, if not in person, then indirectly through surveys, questionnaires or polls. The mechanism is less important than actually reaching out and engaging with them, because without that understanding it\u2019s impossible to start to design with any empathy.\n\nWhat\n\nOnce you become deeply involved directly with a product or service, it\u2019s notoriously difficult to see things as an outsider would. You learn the thing inside and out, you develop shortcuts and internal phraseology. Colloquialisms creep in. You become too close. So it\u2019s no surprise when clients sometimes struggle to explain what it is their product actually does in a way that others can understand.\n\nOften products are complex but, really, the core reasons behind someone wanting to use that product are very simple. There\u2019s a value proposition for the customer and, if they choose to engage with it, there\u2019s a value exchange. If that proposition or exchange isn\u2019t transparent, then people become confused and will likely go elsewhere. Make sure both your client and you really understand what that proposition is and, in turn, what the expected exchange should be. In a nutshell: what is the intended outcome of that engagement? Often the best way to do this is strip everything back to nothing. Verbosity is rife on the web. Just because it\u2019s easy to create content, that shouldn\u2019t be a reason to do so. Figure out what the value proposition is and then reintroduce content elements that genuinely help explain or present that to a level that is appropriate for the audience. \n\nWhy \n\nIn advertising, they talk about the truths behind a product or service. Truths can be both tangible or abstract, but the most important part is the resonance those truths hit with a customer. In a digital product or service those truths are often exposed as benefits. Why is this what I need? Why will it work for me? Why should I trust you? The why is one of the more fluffy Ws, yet it\u2019s such an important one to nail. Clients can get prickly when you ask them to justify the why behind their product, but it\u2019s a fantastic way to make sure the value proposition is clear, realistic and meets with the expectations of both client and customer.\n\nIt\u2019s our job as designers to question things: we\u2019re not just a pair of hands for clients. Just recently I spoke to a potential client about a site for his business. I asked him why people would use his product and also why his product seemed so fractured in its direction. He couldnt answer that question so, instead of ploughing on regardless, he went back to his directors and is now re-evaluating that business. It was awkward but he thanked me and hopefully he\u2019ll have a better product as a result.\n\nWhere\n\nIn this instance, where is not so much a geographical thing, although in some cases that level of context may indeed become a influencing factor\u2026 The where we\u2019re talking about here is the position of the product in relation to others around it. By looking at competitors or similar services around the one you are designing, you can start to get a sense for many of the things that are otherwise hard to pin down or have yet to be defined. For example, in a collection of sites all selling cars, where does yours fit most closely? Where are the overlaps? How are they communicating to their customers? How is the product range presented or categorized?\n\nIt\u2019s good to look around and see how others are doing it. Not in a quest for homogeneity but more to reference or to avoid certain patterns that may or may not make sense for your own particular product. Clients often strive to be different for the sake of it. They feel they need to provide distinction by going against the flow a bit. We know different. We know users love convention. They embrace familiar mental models. They\u2019re comfortable with things that they\u2019ve experienced elsewhere. By showing your client that position is a vital part of their strategy, you can help shape their product into something great. \n\nTo conclude\n\nSo there we have it \u2013 the four Ws. Each part tells a different and vital part of the story you need to be able to make a really good product. It might sound like a lot of work, particularly when the client is breathing down your neck expecting to see things, but without those pieces in place, the story you\u2019re building your product on, and the content that you\u2019re creating to form that product can only ever fit into one genre.

{"rowid": 283, "title": "CSS3 Patterns, Explained", "contents": "Many of you have probably seen my CSS3 patterns gallery. It became very popular throughout the year and it showed many web developers how powerful CSS3 gradients really are. But how many really understand how these patterns are created? The biggest benefit of CSS-generated backgrounds is that they can be modified directly within the style sheet. This benefit is void if we are just copying and pasting CSS code we don\u2019t understand. We may as well use a data URI instead.\n\nImportant note\n\nIn all the examples that follow, I\u2019ll be using gradients without a vendor prefix, for readability and brevity. However, you should keep in mind that in reality you need to use all the vendor prefixes (-moz-, -ms-, -o-, -webkit-) as no browser currently implements them without a prefix. Alternatively, you could use -prefix-free and have the current vendor prefix prepended at runtime, only when needed.\n\nThe syntax described here is the one that browsers currently implement. The specification has since changed, but no browser implements the changes yet. If you are interested in what is coming, I suggest you take a look at the dev version of the spec.\n\nIf you are not yet familiar with CSS gradients, you can read these excellent tutorials by John Allsopp and return here later, as in the rest of the article I assume you already know the CSS gradient basics:\n\n\n\tCSS3 Linear Gradients\n\tCSS3 Radial Gradients\n\n\nThe main idea\n\nI\u2019m sure most of you can imagine the background this code generates:\n\nbackground: linear-gradient(left, white 20%, #8b0 80%);\n\nIt\u2019s a simple gradient from one color to another that looks like this:\n\n See this example live\n\nAs you probably know, in this case the first 20% of the container\u2019s width is solid white and the last 20% is solid green. The other 60% is a smooth gradient between these colors. Let\u2019s try moving these color stops closer to each other:\n\nbackground: linear-gradient(left, white 30%, #8b0 70%);\n\n See this example live\n\nbackground: linear-gradient(left, white 40%, #8b0 60%);\n\n See this example live\n\nbackground: linear-gradient(left, white 50%, #8b0 50%);\n\n See this example live\n\nNotice how the gradient keeps shrinking and the solid color areas expanding, until there is no gradient any more in the last example. We can even adjust the position of these two color stops to control where each color abruptly changes into another:\n\nbackground: linear-gradient(left, white 30%, #8b0 30%);\n\n See this example live\n\nbackground: linear-gradient(left, white 90%, #8b0 90%);\n\n See this example live\n\nWhat you need to take away from these examples is that when two color stops are at the same position, there is no gradient, only solid colors. Even without going any further, this trick is useful for a number of different use cases like faux columns or the effect I wanted to achieve in my homepage or the -prefix-free page where the background is only shown on one side and hidden on the other:\n\n\n\nCombining with background-size\n\nWe can do wonders, however, if we combine this with the CSS3 background-size property:\n\nbackground: linear-gradient(left, white 50%, #8b0 50%);\nbackground-size: 100px 100px;\n\n See this example live\n\nAnd there it is. We just created the simplest of patterns: (vertical) stripes. We can remove the first parameter (left) or replace it with top and we\u2019ll get horizontal stripes. However, let\u2019s face it: Horizontal and vertical stripes are kinda boring. Most stripey backgrounds we see on the web are diagonal. So, let\u2019s try doing that.\n\nOur first attempt would be to change the angle of the gradient to something like 45deg. However, this results in an ugly pattern like this: \n\n See this example live\n\nBefore reading on, think for a second: why didn\u2019t this produce the desired result? Can you figure it out?\n\nThe reason is that the gradient angle rotates the gradient inside each tile, not the tiled background as a whole. However, didn\u2019t we have the same problem the first time we tried to create diagonal stripes with an image? And then we learned that every stripe has to be included twice, like so:\n\n\n\nSo, let\u2019s try to create that effect with CSS gradients. It\u2019s essentially what we tried before, but with more color stops:\n\nbackground: linear-gradient(45deg, white 25%,\n    #8b0 25%, #8b0 50%, \n    white 50%, white 75%, \n    #8b0 75%);\nbackground-size:100px 100px;\n\n See this example live\n\nAnd there we have our stripes! An easy way to remember the order of the percentages and colors it is that you always have two of the same in succession, except the first and last color.\n\nNote: Firefox for Mac also needs an additional 100% color stop at the end of any pattern with more than two stops, like so: ..., white 75%, #8b0 75%, #8b0). The bug was reported in February 2011 and you can vote for it and track its progress at Bugzilla.\n\nUnfortunately, this is essentially a hack and we will realize that if we try to change the gradient angle to 60deg:\n\n See this example live\n\nNot that maintainable after all, eh? Luckily, CSS3 offers us another way of declaring such backgrounds, which not only helps this case but also results in much more concise code:\n\nbackground: repeating-linear-gradient(60deg, white, white 35px, #8b0 35px, #8b0 70px);\n\n See this example live\n\nIn this case, however, the size has to be declared in the color stop positions and not through background-size, since the gradient is supposed to cover the entire container. You might notice that the declared size is different from the one specified the previous way. This is because the size of the stripes is measured differently: in the first example we specify the dimensions of the tile itself; in the second, the width of the stripes (35px), which is measured diagonally.\n\nMultiple backgrounds\n\nUsing only one gradient you can create stripes and that\u2019s about it. There are a few more patterns you can create with just one gradient (linear or radial) but they are more or less boring and ugly. Almost every pattern in my gallery contains a number of different backgrounds. For example, let\u2019s create a polka dot pattern:\n\nbackground: radial-gradient(circle, white 10%, transparent 10%),\nradial-gradient(circle, white 10%, black 10%) 50px 50px;\nbackground-size:100px 100px;\n\n See this example live\n\nNotice that the two gradients are almost the same image, but positioned differently to create the polka dot effect. The only difference between them is that the first (topmost) gradient has transparent instead of black. If it didn\u2019t have transparent regions, it would effectively be the same as having a single gradient, as the topmost gradient would obscure everything beneath it.\n\nThere is an issue with this background. Can you spot it?\n\nThis background will be fine for browsers that support CSS gradients but, for browsers that don\u2019t, it will be transparent as the whole declaration is ignored. We have two ways to provide a fallback, each for different use cases. We have to either declare another background before the gradient, like so:\n\nbackground: black;\nbackground: radial-gradient(circle, white 10%, transparent 10%),\nradial-gradient(circle, white 10%, black 10%) 50px 50px;\nbackground-size:100px 100px;\n\nor declare each background property separately:\n\nbackground-color: black;\nbackground-image: radial-gradient(circle, white 10%, transparent 10%),\nradial-gradient(circle, white 10%, transparent 10%);\nbackground-size:100px 100px;\nbackground-position: 0 0, 50px 50px;\n\nThe vigilant among you will have noticed another change we made to our code in the last example: we altered the second gradient to have transparent regions as well. This way background-color serves a dual purpose: it sets both the fallback color and the background color of the polka dot pattern, so that we can change it with just one edit. Always strive to make code that can be modified with the least number of edits. You might think that it will never be changed in that way but, almost always, given enough time, you\u2019ll be proved wrong.\n\nWe can apply the exact same technique with linear gradients, in order to create checkerboard patterns out of right triangles:\n\nbackground-color: white;\nbackground-image: linear-gradient(45deg, black 25%, transparent 25%, transparent 75%, black 75%), \nlinear-gradient(45deg, black 25%, transparent 25%, transparent 75%, black 75%);\nbackground-size:100px 100px;\nbackground-position: 0 0, 50px 50px;\n\n See this example live\n\nUsing the right units\n\nDon\u2019t use pixels for the sizes without any thought. In some cases, ems make much more sense. For example, when you want to make a lined paper background, you want the lines to actually follow the text. If you use pixels, you have to change the size every time you change font-size. If you set the background-size in ems, it will naturally follow the text and you will only have to update it if you change line-height.\n\nIs it possible?\n\nThe shapes that can be achieved with only one gradient are:\n\n\n\tstripes\n\tright triangles\n\tcircles and ellipses\n\tsemicircles and other shapes formed from slicing ellipses horizontally or vertically\n\n\nYou can combine several of them to create squares and rectangles (two right triangles put together), rhombi and other parallelograms (four right triangles), curves formed from parts of ellipses, and other shapes.\n\nJust because you can doesn\u2019t mean you should\n\nTechnically, anything can be crafted with these techniques. However, not every pattern is suitable for it. The main advantages of this technique are:\n\n\n\tno extra HTTP requests\n\tshort code\n\thuman-readable code (unlike data URIs) that can be changed without even leaving the CSS file.\n\n\nComplex patterns that require a large number of gradients are probably better left to SVG or bitmap images, since they negate almost every advantage of this technique:\n\n\n\tthey are not shorter\n\tthey are not really comprehensible \u2013 changing them requires much more effort than using an image editor\n\n\nThey still save an HTTP request, but so does a data URI.\n\nI have included some very complex patterns in my gallery, because even though I think they shouldn\u2019t be used in production (except under very exceptional conditions), understanding how they work and coding them helps somebody understand the technology in much more depth.\n\nAnother rule of thumb is that if your pattern needs shapes to obscure parts of other shapes, like in the star pattern or the yin yang pattern, then you probably shouldn\u2019t use it. In these patterns, changing the background color requires you to also change the color of these shapes, making edits very tedious.\n\nIf a certain pattern is not practicable with a reasonable amount of CSS, that doesn\u2019t mean you should resort to bitmap images. SVG is a very good alternative and is supported by all modern browsers.\n\nBrowser support\n\nCSS gradients are supported by Firefox 3.6+, Chrome 10+, Safari 5.1+ and Opera 11.60+ (linear gradients since Opera 11.10). Support is also coming in Internet Explorer when IE10 is released. You can get gradients in older WebKit versions (including most mobile browsers) by using the proprietary -webkit-gradient(), if you really need them.\n\nEpilogue\n\nI hope you find these techniques useful for your own designs. If you come up with a pattern that\u2019s very different from the ones already included, especially if it demonstrates a cool new technique, feel free to send a pull request to the github repo of the patterns gallery. Also, I\u2019m always fascinated to see my techniques put in practice, so if you made something cool and used CSS patterns, I\u2019d love to know about it!\n\nHappy holidays!", "year": "2011", "author": "Lea Verou", "author_slug": "leaverou", "published": "2011-12-16T00:00:00+00:00", "url": "https://24ways.org/2011/css3-patterns-explained/", "topic": "code"}
{"rowid": 56, "title": "Helping VIPs Care About Performance", "contents": "Making a site feel super fast is the easy part of performance work. Getting people around you to care about site speed is a much bigger challenge. How do we keep the site fast beyond the initial performance work? Keeping very important people like your upper management or clients invested in performance work is critical to keeping a site fast and empowering other designers and developers to contribute.\nThe work to get others to care is so meaty that I dedicated a whole chapter to the topic in my book Designing for Performance. When I speak at conferences, the majority of questions during Q&A are on this topic. When I speak to developers and designers who care about performance, getting other people at one\u2019s organization or agency to care becomes the most pressing question.\nMy primary response to folks who raise this issue is the question: \u201cWhat metric(s) do your VIPs care about?\u201d This is often met with blank stares and raised eyebrows. But it\u2019s also our biggest clue to what we need to do to help empower others to care about performance and work on it. Every organization and executive is different. This means that three major things vary: the primary metrics VIPs care about; the language they use about measuring success; and how change is enacted. By clueing in to these nuances within your organization, you can get a huge leg up on crafting a successful pitch about performance work.\nLet\u2019s start with the metric that we should measure. Sure, (most) everybody cares about money - but is that really the metric that your VIPs are looking at each day to measure the success or efficacy of your site? More likely, dollars are the end game, but the metrics or key performance indicators (KPIs) people focus on might be:\n\nrate of new accounts created/signups\ncost of acquiring or retaining a customer\nvisitor return rate\nvisitor bounce rate\nfavoriting or another interaction rate\n\nThese are just a few examples, but they illustrate how wide-ranging the options are that people care about. I find that developers and designers haven\u2019t necessarily investigated this when trying to get others to care about performance. We often reach for the obvious \u2013 money! \u2013 but if we don\u2019t use the same kind of language our VIPs are using, we might not get too far. You need to know this before you can make the case for performance work.\nTo find out these metrics or KPIs, start reading through the emails your VIPs are sending within your company. What does it say on company wikis? Are there major dashboards internally that people are looking at where you could find some good metrics? Listen intently in team meetings or thoroughly read annual reports to see what these metrics could be.\nThe second key here is to pick up on language you can effectively copy and paste as you make the case for performance work. You need to be able to reflect back the metrics that people already find important in a way they\u2019ll be able to hear. Once you know your key metrics, it\u2019s time to figure out how to communicate with your VIPs about performance using language that will resonate with them.\nLet\u2019s start with visit traffic as an example metric that a very important person cares about. Start to dig up research that other people and companies have done that correlates performance and your KPI. For example, cite studies:\n\n\u201cWhen the home page of Google Maps was reduced from 100KB to 70\u201380KB, traffic went up 10% in the first week, and an additional 25% in the following three weeks.\u201d (source).\n\nRead through websites like WPOStats, which collects the spectrum of studies on the impact of performance optimization on user experience and business metrics. Tweet and see if others have done similar research that correlates performance and your site\u2019s main KPI.\nOnce you have collected some research that touches on the same kind of language your VIPs use about the success of your site, it\u2019s time to present it. You can start with something simple, like a qualitative description of the work you\u2019re actively doing to improve the site that translates to improved metrics that your VIPs care about. It can be helpful to append a performance budget to any proposal so you can compare the budget to your site\u2019s reality and how it might positively impact those KPIs folks care about.\nWords and graphs are often only half the battle when it comes to getting others to care about performance. Often, videos appeal to folks\u2019 emotions in a way that is missed when glancing through charts and graphs. On A List Apart I recently detailed how to create videos of how fast your site loads. Let\u2019s say that your VIPs care about how your site loads on mobile devices; it\u2019s time to show them how your site loads on mobile networks.\nOpen video\n\nYou can use these videos to make a number of different statements to your VIPs, depending on what they care about:\n\nLook at how slow our site loads versus our competitor!\nLook at how slow our site loads for users in another country!\nLook at how slow our site loads on mobile networks!\n\nAgain, you really need to know which metrics your VIPs care about and tune into the language they\u2019re using. If they don\u2019t care about the overall user experience of your site on mobile devices, then showing them how slow your site loads on 3G isn\u2019t going to work. This will be your sales pitch; you need to practice and iterate on the language and highlights that will land best with your audience. \nTo make your sales pitch as solid as possible, gut-check your ideas on how to present it with other co-workers to get their feedback. Read up on how to construct effective arguments and deliver them; do some research and see what others have done at your company when pitching to VIPs. Are slides effective? Memos or emails? Hallway conversations? Sometimes the best way to change people\u2019s minds is by mentioning it in informal chats over coffee. Emulate the other leaders in your organization who are successful at this work. \nEvery organization and very important person is different. Learn what metrics folks truly care about, study the language that they use, and apply what you\u2019ve learned in a way that\u2019ll land with those individuals. It may take time to craft your pitch for performance work over time, but it\u2019s important work to do. If you\u2019re able to figure out how to mirror back the language and metrics VIPs care about, and connect the dots to performance for them, you will have a huge leg up on keeping your site fast in the long run.", "year": "2015", "author": "Lara Hogan", "author_slug": "larahogan", "published": "2015-12-08T00:00:00+00:00", "url": "https://24ways.org/2015/helping-vips-care-about-performance/", "topic": "business"}
{"rowid": 237, "title": "Circles of Confusion", "contents": "Long before I worked on the web, I specialised in training photographers how to use large format,  5\u00d74\u2033 and 10\u00d78\u2033 view cameras \u2013 film cameras with swing and tilt movements, bellows and upside down, back to front images viewed on dim, ground glass screens. It\u2019s been fifteen years since I clicked a shutter on a view camera, but some things have stayed with me from those years.\n\nIn photography, even the best lenses don\u2019t focus light onto a point (infinitely small in size) but onto \u2018spots\u2019 or circles in the \u2018film/image plane\u2019. These circles of light have dimensions, despite being microscopically small. They\u2019re known as \u2018circles of confusion\u2019.\n\nAs circles of light become larger, the more unsharp parts of a photograph appear. On the flip side, when circles are smaller, an image looks sharper and more in focus. This is the basis for photographic depth of field and with that comes the knowledge that no photograph can be perfectly focused, never truly sharp. Instead, photographs can only be \u2018acceptably unsharp\u2019. \n\nAcceptable unsharpness is now a concept that\u2019s relevant to the work we make for the web, because often \u2013 unless we compromise \u2013 websites cannot look or be experienced exactly the same across browsers, devices or platforms. Accepting that fact, and learning to look upon these natural differences as creative opportunities instead of imperfections, can be tough. Deciding which aspects of a design must remain consistent and, therefore, possibly require more time, effort or compromises can be tougher. Circles of confusion can help us, our bosses and our customers make better, more informed decisions.\n\nAcceptable unsharpness\n\nMany clients still demand that every aspect of a design should be \u2018sharp\u2019 \u2013 that every user must see rounded boxes, gradients and shadows \u2013 without regard for the implications. I believe that this stems largely from the fact that they have previously been shown designs \u2013 and asked for sign-off \u2013 using static images.\n\nIt\u2019s also true that in the past, organisations have invested heavily in style guides which, while maybe still useful in offline media, have a strictness that often fails to allow for the flexibility that we need to create experiences that are appropriate to a user\u2019s browser or device capabilities.\n\nWe live in an era where web browsers and devices have wide-ranging capabilities, and websites can rarely look or be experienced exactly the same across them. Is a particular typeface vital to a user\u2019s experience of a brand? How important are gradients or shadows? Are rounded corners really that necessary? These decisions determine how \u2018sharp\u2019 an element should be across browsers with different capabilities and, therefore, how much time, effort or extra code and images we devote to achieving consistency between them. To help our clients make those decisions, we can use circles of confusion.\n\nCircles of confusion\n\nUsing circles of confusion involves plotting aspects of a visual design into a series of concentric circles, starting at the centre with elements that demand the most consistency. Then, work outwards, placing elements in order of their priority so that they become progressively \u2018softer\u2019, more defocused as they\u2019re plotted into outer rings.\n\nIf layout and typography must remain consistent, place them in the centre circle as they\u2019re aspects of a design that must remain \u2018sharp\u2019.\n\nWhen gradients are important \u2013 but not vital \u2013 to a user\u2019s experience of a brand, plot them close to, but not in the centre. This makes everyone aware that to achieve consistency, you\u2019ll need to carve out extra images for browsers that don\u2019t support CSS gradients.\n\nIf achieving rounded corners or shadows in all browsers isn\u2019t important, place them into outer circles, allowing you to save time by not creating images or employing JavaScript workarounds.\n\nI\u2019ve found plotting aspects of a visual design into circles of confusion is a useful technique when explaining the natural differences between browsers to clients. It sets more realistic expectations and creates an environment for more meaningful discussions about progressive and emerging technologies. Best of all, it enables everyone to make better and more informed decisions about design implementation priorities.\n\nInvolving clients allows the implications of the decisions they make more transparent. For me, this has sometimes meant shifting deadlines or it has allowed me to more easily justify an increase in fees. Most important of all, circles of confusion have helped the people that I work with move beyond yesterday\u2019s one-size-fits-all thinking about visual design, towards accepting the rich diversity of today\u2019s web.", "year": "2010", "author": "Andy Clarke", "author_slug": "andyclarke", "published": "2010-12-23T00:00:00+00:00", "url": "https://24ways.org/2010/circles-of-confusion/", "topic": "process"}
{"rowid": 83, "title": "Cut Copy Paste", "contents": "Long before I got into this design thing, I was heavily into making my own music inspired by the likes of Coldcut and Steinski. I would scour local second-hand record shops in search of obscure beats, loops and bits of dialogue in the hope of finding that killer sample I could then splice together with other things to make a huge hit that everyone would love. While it did eventually lead to a record contract and getting to release a few 12\u2033 singles, ultimately I knew I\u2019d have to look for something else to pay the bills.\n\nI may not make my own records any more, but the approach I took back then \u2013 finding (even stealing) things, cutting and pasting them into interesting combinations \u2013 is still at the centre of how I work, only these days it\u2019s pretty much bits of code rather than bits of vinyl. Over the years I\u2019ve stored these little bits of code (some I\u2019ve found, some I\u2019ve created myself) in Evernote, ready to be dialled up whenever I need them. \n\nSo when Drew got in touch and asked if I\u2019d like to do something for this year\u2019s 24 ways I thought it might be kind of cool to share with you a few of these snippets that I find really useful. Think of these as a kind of coding mix tape; but remember \u2013 don\u2019t just copy as is: play around, combine and remix them into other wonderful things. \n\nSome of this stuff is dirty; some of it will make hardcore programmers feel ill. For those people, remember this \u2013 while you were complaining about the syntax, I made something.\n\nCreate unique colours\n\nLet\u2019s start right away with something I stole. Well, actually it was given away at the time by Matt Biddulph who was then at Dopplr before Nokia destroyed it. Imagine you have thousands of words and you want to assign each one a unique colour. Well, Matt came up with a crazily simple but effective way to do that using an MD5 hash. Just encode said word using an MD5 hash, then take the first six characters of the string you get back to create a hexadecimal colour representation. \n\nI can\u2019t guarantee that it will be a harmonious colour palette, but it\u2019s still really useful. The thing I love the most about this technique is the left-field thinking of using an encryption system to create colours! Here\u2019s an example using JavaScript:\n\n// requires the MD5 library available at http://pajhome.org.uk/crypt/md5\n\n  function MD5Hex(str){\n    result = MD5.hex(str).substring(0, 6);\n    return result;\n  }\n\nMake something breathe using a sine wave\n\nI never paid attention in school, especially during double maths. As a matter of fact, the only time I received corporal punishment \u2013 several strokes of the ruler \u2013 was in maths class. Anyway, if they had shown me then how beautiful mathematics actually is, I might have paid more attention. Here\u2019s a little example of how a sine wave can be used to make something appear to breathe. \n\nI recently used this on an Arduino project where an LED ring surrounding a button would gently breathe. Because of that it felt much more inviting. I love mathematics.\n\nfor(int i = 0; i<360; i++){    \n  float rad = DEG_TO_RAD * i;\n  int sinOut = constrain((sin(rad) * 128) + 128, 0, 255);\n  analogWrite(LED, sinOut);\n  delay(10);   \n}\n\nSnap position to grid\n\nThis is so elegant I love it, and it was shown to me by Gary Burgess, or Boom Boom as myself and others like to call him. It snaps a position, in this case the X-position, to a grid. Just define your grid size (say, twenty pixels) and you\u2019re good.\n\nsnappedXpos = floor( xPos / gridSize) * gridSize;\n\nCalculate the distance between two objects\n\nFor me, interaction design is about the relationship between two objects: you and another object; you and another person; or simply one object to another. How close these two things are to each other can be a handy thing to know, allowing you to react to that information within your design. Here\u2019s how to calculate the distance between two objects in a 2-D plane:\n\ndeltaX = round(p2.x-p1.x);\ndeltaY = round(p2.y-p1.y);\ndiff = round(sqrt((deltaX*deltaX)+(deltaY*deltaY)));\n\nFind the X- and Y-position between two objects\n\nWhat if you have two objects and you want to place something in-between them? A little bit of interruption and disruption can be a good thing. This small piece of code will allow you to place an object in-between two other objects:\n\n// set the position: 0.5 = half-way\t\n\nfloat position = 0.5;\nfloat x = x1 + (x2 - x1) *position;  \nfloat y = y1 + (y2 - y1) *position;  \n\nDistribute objects equally around a circle \t\n\nMore fun with maths, this time adding cosine to our friend sine. Let\u2019s say you want to create a circular navigation of arbitrary elements (yeah, Jakob, you heard), or you want to place images around a circle. Well, this piece of code will do just that. You can adjust the size of the circle by changing the distance variable and alter the number of objects with the numberOfObjects variable. Example below is for use in Processing.\n\n// Example for Processing available for free download at processing.org\n\nvoid setup() {\n\n  size(800,800);\n  int numberOfObjects = 12;\n  int distance = 100;\n  float inc = (TWO_PI)/numberOfObjects;\n  float x,y;\n  float a = 0;\n\n  for (int i=0; i < numberOfObjects; i++) {\n    x = (width/2) + sin(a)*distance;\n    y = (height/2) + cos(a)*distance;\n    ellipse(x,y,10,10);\n    a += inc;\n\n  }\n}\n\nUse modulus to make a grid\n\nThe modulus operator, represented by %, returns the remainder of a division. Fallen into a coma yet? Hold on a minute \u2013 this seemingly simple function is very powerful in lots of ways. At a simple level, you can use it to determine if a number is odd or even, great for creating alternate row colours in a table for instance:\n\nboolean checkForEven(numberToCheck) {\n  if (numberToCheck % 2 == 0) \n    return true;\n  } else {\n    return false; \n  }\n}\n\nThat\u2019s all well and good, but here\u2019s a use of modulus that might very well blow your mind. Construct a grid with only a few lines of code. Again the example is in Processing but can easily be ported to any other language.\n\nvoid setup() {\n\nsize(600,600);\nint numItems = 120;\nint numOfColumns = 12;\nint xSpacing = 40;\nint ySpacing = 40;\nint totalWidth = xSpacing*numOfColumns;\n\nfor (int i=0; i < numItems; i++) {\n\nellipse(floor((i*xSpacing)%totalWidth),floor((i*xSpacing)/totalWidth)*ySpacing,10,10);\n\n}\n}\n\nNot all the bits of code I keep around are for actual graphical output. I also have things that are very utilitarian, but which I still consider part of the design process. Here\u2019s a couple of things that I\u2019ve found really handy lately in my design workflow. They may be a little specific, but I hope they demonstrate that it\u2019s not about working harder, it\u2019s about working smarter. \n\nMerge CSV files into one file\n\nRecently, I\u2019ve had to work with huge \u2013 about 1GB \u2013 CSV text files that I then needed to combine into one master CSV file so I could then process the data. Opening up each text file and then copying and pasting just seemed really dumb, not to mention slow, so I thought there must be a better way. After some Googling I found this command line script that would combine .txt files into one file and add a new line after each:  \n\nawk 1 *.txt > finalfile.txt\n\nBut that wasn\u2019t what I was ideally after. I wanted to merge the CSV files, keeping the first row of the first file (the column headings) and then ignore the first row of subsequent files. Sure enough I found the answer after some Googling and it worked like a charm. Apologies to the original author but I can\u2019t remember where I found it, but you, sir or madam, are awesome. Save this as a shell script:\n\nFIRST=\n\nfor FILE in *.csv\n  do\n    exec 5<\"$FILE\" # Open file\n    read LINE <&5 # Read first line\n      [ -z \"$FIRST\" ] && echo \"$LINE\" # Print it only from first file\n      FIRST=\"no\"\n\n      cat <&5 # Print the rest directly to standard output\n      exec 5<&- # Close file\n      # Redirect stdout for this section into file.out \n\ndone > file.out\n\nCreate a symbolic link to another file or folder\n\nOftentimes, I\u2019ll find myself hunting through a load of directories to load a file to be processed, like a CSV file. Use a symbolic link (in the Terminal) to place a link on your desktop or wherever is most convenient and it\u2019ll save you loads of time. Especially great if you\u2019re going through a Java file dialogue box in Processing or something that doesn\u2019t allow the normal Mac dialog box or aliases.\n\ncd /DirectoryYouWantShortcutToLiveIn\nln -s /Directory/You/Want/ShortcutTo/ TheShortcut\n\nYou can do it, in the mix\n\nI hope you\u2019ve found some of the above useful and that they\u2019ve inspired a few ideas here and there. Feel free to tell me better ways of doing things or offer up any other handy pieces of code. Most of all though, collect, remix and combine the things you discover to make lovely new things.", "year": "2012", "author": "Brendan Dawes", "author_slug": "brendandawes", "published": "2012-12-17T00:00:00+00:00", "url": "https://24ways.org/2012/cut-copy-paste/", "topic": "code"}
{"rowid": 14, "title": "The Command Position Principle", "contents": "Living where I do, in a small village in rural North Wales, getting anywhere means driving along narrow country roads. Most of these are just about passable when two cars meet. \n\nIf you\u2019re driving too close to the centre of the road, when two drivers meet you stop, glare at each other and no one goes anywhere. Drive too close to your nearside and in summer you\u2019ll probably scratch your paintwork on the hedgerows, or in winter you\u2019ll sink your wheels into mud. \n\nDriving these lanes requires a balance between caring for your own vehicle and consideration for someone else\u2019s, but all too often, I\u2019ve seen drivers pushed towards the hedgerows and mud when someone who\u2019s inconsiderate drives too wide because they don\u2019t want to risk scratching their own paintwork or getting their wheels dirty.\n\nIf you learn to ride a motorcycle,\u00a0you\u2019ll be taught about the command position:\n\n\n\tApproximate central position, or any position from which the rider can exert control over invitation space either side.\n\n\nThe command position helps motorcyclists stay safe, because when they ride in the centre of their lane it prevents other people, usually car drivers, from driving alongside, either forcing them into the curb or potentially dangerously close to oncoming traffic. \n\nTaking the command position isn\u2019t about motorcyclists being aggressive, it\u2019s about them being confident. It\u2019s them knowing their rightful place on the road and communicating that through how they ride.\n\nI\u2019ve recently been trying to take that command position when driving my car on our lanes. When I see someone coming in the opposite direction, instead of instinctively moving closer to my nearside \u2014 and in so doing subconsciously invite them into my space on the road \u2014 I hold both my nerve and a central position in my lane. Since I done this I\u2019ve noticed that other drivers more often than not stay in their lane or pull closer to their nearside so we occupy equal space on the road. Although we both still need to watch our wing mirrors, neither of us gets our paint scratched or our wheels muddy.\n\nWe can apply this principle to business too, in particular to negotiations and the way we sell. Here\u2019s how we might do that.\n\nCommanding negotiations\n\nWhen a customer\u2019s been sold to well \u2014\u00a0more on that in just a moment \u2014 and they\u2019ve made the decision to buy, the thing that usually stands in the way of us doing business is a negotiation over price. Some people treat negotiations as the equivalent of driving wide. They act offensively, because their aim is to force the other person into getting less, usually in return for giving more.\n\nIn encounters like this, it\u2019s easy for us to act defensively. We might lack confidence in the price we ask for, or the value of the product or service we offer. We might compromise too early because of that. When that happens, there\u2019s a pretty good chance that we\u2019ll drive away with less than we deserve unless we use the command position principle to help us.\n\nBefore we start any negotiation it\u2019s important to know that both sides ultimately want to reach an agreement. This isn\u2019t always obvious. If one side isn\u2019t already committed, at least in principle, then it\u2019s not a negotiation at that point, it\u2019s something else. \n\nFor example, a prospective customer may be looking to learn our lowest price so that they can compare it to our competitors. When that\u2019s the case, we\u2019ve probably failed to qualify that prospect properly as, after all, who wants to be chosen simply because they\u2019re the cheapest? In this situation, negotiating is a waste of time since we don\u2019t yet know that it will result in us making a deal. We should enter into a negotiation only when we know where we stand. So ask confidently: \u201cAre you looking to [make a decision]?\u201d\n\nWhen that\u2019s been confirmed, it\u2019s down to everyone to compromise until a deal\u2019s been reached. That\u2019s because good negotiations aren\u2019t about one side beating the other, they\u2019re about achieving a good deal for both. Using the command position principle helps us to maintain control over our negotiating space and affords us the opportunity to give ground only if we need to and only when we\u2019re ready. It can also ensure that the person we\u2019re negotiating with gives up some of their space.\n\nCommanding sales\n\nIt\u2019s not always necessary to negotiate when we\u2019re doing a business deal, but we should always be prepared to sell. One of the most important parts of our sales process should be controlling when and how we tell someone our price. \n\nUnless it\u2019s impossible to avoid, don\u2019t work out a price for someone on the spot. When we do that we lose control over the time and place for presenting our price alongside the value factors that will contribute to the prospective customer accepting that price. For the same reason, never give a ballpark or, worse, a guesstimate figure. If the question of price comes up before we\u2019re fully prepared, we should say politely that we need more time to work out a meaningful cost. \n\nWhen we are ready, we shouldn\u2019t email a price for our prospective customer to read unaccompanied. Instead, create an opportunity to talk a prospect through our figures, demonstrate how we arrived at them and, most importantly, explain the value of what we\u2019re selling to their business. Agree a time and place to do this and, if possible, do it all face-to-face.  \n\nWe shouldn\u2019t hesitate when we give someone a price. When we sound even the slightest bit unsure or apologetic, we give the impression that we\u2019ll be flexible in our position before negotiations have even begun.\n\nThink about the command position principle, know the price and present it confidently. That way we send a clear signal that we know our business and how we deal with people. The command position principle isn\u2019t about being cocky, it\u2019s about showing other people respect, asking for it in return and showing it to ourselves.\n\n \n\nEarlier, I mentioned selling well, because we sometimes hear people say that they dislike being sold to. In my experience, it\u2019s not that people dislike the sales process, it\u2019s that we dislike it done badly.\n\nTaking part in a good sales process, either by selling or being sold to, can be a pleasurable experience. Try to be confident \u2014 after all, we understand how our skills will benefit a customer better than anyone else. Our confidence will inspire confidence in others. \n\nSelf-confidence isn\u2019t the same as arrogance, just as the command position isn\u2019t the same as riding without consideration for others. The command position principle preserves others\u2019 space as well as our own. By the same token, we should be considerate of others\u2019 time and not waste it and our own by attempting to force them into buying something that\u2019s inappropriate.\n\nTo prevent this from happening, evaluate them well to ensure that they\u2019re the right customer for us. If they\u2019re not, let them go on their way. They\u2019ll thank us for it and may well become customers the next time we meet.\n\nThe business of closing a deal can be made an enjoyable experience for everyone if we take control by guiding someone through the sales process by asking the right questions to uncover their concerns, then allaying them by being knowledgeable and confident. This is riding in the command position.\n\nJust like demonstrating we know our rightful position on the road, knowing our rightful place in a business relationship and communicating that through how we deal with people will help everyone achieve an equitable balance. When that happens in business, as well as on the road, no one gets their paintwork scratched or their wheels muddy.", "year": "2013", "author": "Andy Clarke", "author_slug": "andyclarke", "published": "2013-12-23T00:00:00+00:00", "url": "https://24ways.org/2013/the-command-position-principle/", "topic": "business"}
{"rowid": 59, "title": "Animating Your Brand", "contents": "Let\u2019s talk about how we add animation to our designs, in a way that\u2019s consistent with other aspects of our brand, such as fonts, colours, layouts and everything else.\nAnimating is fun. Adding animation to our designs can bring them to life and make our designs stand out. Animations can show how the pieces of our designs fit together. They provide context and help people use our products.\nAll too often animation is something we tack on at the end. We put a transition on a modal window or sliding menu and we often don\u2019t think about whether that animation is consistent with our overall design.\nStyle guides to the rescue\nA style guide is a document that establishes and enforces style to improve communication. It can cover anything from typography and writing style to ethics and other, broader goals. It might be a static visual document showing every kind of UI, like in the Codecademy.com redesign shown below.\nUI toolkit from \u201cReimagining Codecademy.com\u201d by @mslima\nIt might be a technical reference with code examples. CodePen\u2019s new design patterns and style guide is a great example of this, showing all the components used throughout the website as live code.\nCodePen\u2019s design patterns and style guide\nA style guide gives a wide view of your project, it maintains consistency when adding new content, and we can use our style guide to present animations.\nLiving documents\nStyle guides don\u2019t need to be static. We can use them to show movement. We can share CSS keyframe animations or transitions that can then go into production. We can also explain why animation is there in the first place.\nJust as a style guide might explain why we chose a certain font or layout, we can use style guides to explain the intent behind animation. This means that if someone else wants to create a new component, they will know why animation applies.\nIf you haven\u2019t yet set up a style guide, you might want to take a look at Pattern Lab. It\u2019s a great tool for setting up your own style guide and includes loads of design patterns to get started.\nThere are many style guide articles linked from the excellent, open sourced, Website Style Guide Resources. Anna Debenham also has an excellent pocket book on the subject.\nAdding animation\nBefore you begin throwing animation at all the things, establish the character you want to convey.\nAndrex Puppy (British TV ad from 1994)\nList some words that describe the character you\u2019re aiming for. If it was the Andrex brand, they might have gone for: fun, playful, soft, comforting.\nPerhaps you\u2019re aiming for something more serious, credible and authoritative. Or maybe exciting and intense, or relaxing and meditative. For each scenario, the animations that best represent these words will be different.\nIn the example below, two animations both take the same length of time, but use different timing functions. One eases, and the other bounces around. Either might be good, depending on your needs.\nTiming functions (CodePen)\nExample: Kitman Labs\nWorking with Kitman Labs, we spent a little time working out what words best reflected the brand and came up with the following:\n\nScientific\nPrecise\nFast\nSolid\nDependable\nHelpful\nConsistent\nClear\n\nWith such a list of words in hand, we design animation that fits. We might prefer a tween that moves quickly to its destination over one that drifts slowly or bounces.\nWe can use the list when justifying our use of animation, such as when it helps our customers understand the context of data on the page. Or we may even choose not to animate, when that might make the message inconsistent.\nCreate guidelines\nIf you already have a style guide, adding animation could begin with creating an overview section.\nOne approach is to create a local website and share it within your organisation. We recently set up a local site for this purpose. \nA recent project\u2019s introduction to the topic of animation\nThis document becomes a reference when adding animation to components. Include links to related resources or examples of animation to help demonstrate the animation style you want.\nPrototyping\nYou can explain the intent of your animation style guide with live animations. This doesn\u2019t just mean waving our hands around. We can show animation through prototypes.\nThere are so many prototype tools right now. You could use Invision, Principle, Floid, or even HTML and CSS as embedded CodePens.\nA login flow prototype created in Principle\nThese tools help when trying out ideas and working through several approaches. Create videos, animated GIFs or online demos to share with others. Experiment. Find what works for you and work with whatever lets you get the most ideas out of your head fastest. Iterate and refine an animation before it gets anywhere near production.\nBuild up a collection\nBuild up your guide, one animation at a time.\nSome people prefer to loosely structure a guide with places to put things as they are discovered or invented; others might build it one page at a time \u2013 it doesn\u2019t matter. The main thing is that you collect animations like you would trading cards. Or Pokemon. Keep them ready to play and deliver that explosive result.\nYou could include animated GIFs, or link to videos or even live webpages as examples of animation. The use of animation to help user experience is also covered nicely in Val Head\u2019s UI animation and UX article on A List Apart.\nWhat matters is that you create an organised place for them to be found. Here are some ideas to get started.\nLogos and brandmarks\nMany sites include some subtle form of animation in their logos. This can draw the eye, add some character, or bring a little liveliness to an otherwise static page. Yahoo and Google have been experimenting with animation on their logos. Even a simple bouncing animation, such as the logo on Hop.ie, can add character.\nThe CSS-animated bouncer from Hop.ie\nContent transitions\nAdding content, removing content, showing and hiding messages are all opportunities to use animation. Careful and deliberate use of animation helps convey what\u2019s changing on screen.\nAnimating list items with CSS (CSSAnimation.rocks)\nFor more detail on this, I also recommend \u201cTransitional Interfaces\u201d by Pasquale D\u2019Silva.\nPage transitions\nOn a larger scale than the changes to content, full-page transitions can smooth the flow between sections of a site. Medium\u2019s article transitions are a good example of this.\nMedium-style page transition (Tympanus.net)\nPreparing a layout before the content arrives\nWe can use animation to draw a page before the content is ready, such as when a page calls a server for data before showing it.\nOptimistic loading grid (CodePen)\nSometimes it\u2019s good to show something to let the user know that everything\u2019s going well. A short animation could cover just enough time to load the initial content and make the loading transition feel seamless.\nInteractions\nHover effects, dropdown menus, slide-in menus and active states on buttons and forms are all opportunities. Look for ways you can remove the sudden changes and help make the experience of using your UI feel smoother.\nForm placeholder animation (Studio MDS)\nKeep animation visible\nIt takes continuous effort to maintain a style guide and keep it up to date, but it\u2019s worth it. Make it easy to include animation and related design decisions in your documentation and you\u2019ll be more likely to do so. If you can make it fun, and be proud of the result, better still.\nWhen updating your style guide, be sure to show the animations at the same time. This might mean animated GIFs, videos or live embedded examples of your components.\nBy doing this you can make animation integral to your design process and make sure it stays relevant.\nInspiration and resources\nThere are loads of great resources online to help you get started. One of my favourites is IBM\u2019s design language site.\nIBM\u2019s design language:\u200aanimation design guidelines\nIBM describes how animation principles apply to its UI work and components. They break down the animations into five categories of animations and explain how they apply to each example.\nThe site also includes an animation library with example videos of animations and links to source code.\nExample component from IBM\u2019s component library\nThe way IBM sets out its aims and methods is helpful not only for their existing designers and developers, but also helps new hires. Furthermore, it\u2019s a good way to show the world that IBM cares about these details.\nAnother popular animation resource is Google\u2019s material design.\nGoogle\u2019s material design documentation\nGoogle\u2019s guidelines cover everything from understanding easing through to creating engaging and useful mobile UI.\nThis approach is visible across many of Google\u2019s apps and software, and has influenced design across much of the web. The site is helpful both for learning about animation and as an showcase of how to illustrate examples.\nFrameworks\nIf you don\u2019t want to create everything from scratch, there are resources you can use to start using animation in your UI. One such resource is Salesforce\u2019s Lightning design system.\nThe system goes further than most guides. It includes a downloadable framework for adding animation to your projects. It has some interesting concepts, such as elevation settings to handle positioning on the z-axis.\nExample of elevation from Salesforce\u2019s Lightning design system\nYou should also check out Animate.css.\n\u201cJust add water\u201d\u200a\u2014\u200aAnimate.css\nAnimate.css gives you a set of predesigned animations you can apply to page elements using classes. If you use JavaScript to add or remove classes, you can then trigger complex animations. It also plays well with scroll-triggering, and tools such as WOW.js.\nLearn, evolve and make it your own\nThere\u2019s a wealth online of information and guides we can use to better understand animation. They can inspire and kick-start our own visual and animation styles. So let\u2019s think of the design of animations just as we do fonts, colours and layouts. Let\u2019s choose animation deliberately, making it part of our style guides.\nMany thanks to Val Head for taking the time to proofread and offer great suggestions for this article.", "year": "2015", "author": "Donovan Hutchinson", "author_slug": "donovanhutchinson", "published": "2015-12-01T00:00:00+00:00", "url": "https://24ways.org/2015/animating-your-brand/", "topic": "design"}
{"rowid": 28, "title": "Why You Should Design for Open Source", "contents": "Let\u2019s be honest. Most designers don\u2019t like working for nothing. We rally against spec work and make a stand for contracts and getting paid. That\u2019s totally what you should do as a professional designer in the industry. It\u2019s your job. It\u2019s your hard-working skill. It\u2019s your bread and butter. Get paid.\n\nHowever, I\u2019m going to make a case for why you could also consider designing for open source. First, I should mention that not all open source work is free work. Some companies hire open source contributors to work on their projects full-time, usually because that project is used by said company. There are other companies that encourage open source contribution and even offer 20%-time for these projects (where you can spend one day a week contributing to open source). These are super rad situations to be in. However, whether you\u2019re able to land a gig doing this type of work, or you\u2019ve decided to volunteer your time and energy, designing for open source can be rewarding in many other ways.\n\nPortfolio building\n\nNew designers often find themselves in a catch-22 situation: they don\u2019t have enough work experience showcased in their portfolio, which leads to them not getting much work because their portfolio is bare. These new designers often turn to unsolicited redesigns to fill their portfolio. An unsolicited redesign is a proof of concept in which a designer attempts to redesign a popular website. You can see many of these concepts on sites like Dribbble and Behance and there are even websites dedicated to showcasing these designs, such as Uninvited Designs. There\u2019s even a subreddit for them.\n\nThere are quite a few negative opinions on unsolicited redesigns, though some people see things from both sides. If you feel like doing one or two of these to fill your portfolio, that\u2019s of course up to you. But here\u2019s a better suggestion. Why not contribute design for an open source project instead?\n\nYou can easily find many projects in great need of design work, from branding to information design, documentation, and website or application design. The benefits to doing this are far better than an unsolicited redesign. You get a great portfolio piece that actually has greater potential to get used (especially if the core team is on board with it). It\u2019s a win-win situation.\n\nNot all designers are in need of portfolio filler, but there are other benefits to contributing design.\n\nGiving back to the community\n\nMy first experience with voluntary work was when I collaborated with my friend, Vineet Thapar, on a pro bono project for the W3C\u2019s Web Accessibility Initiative redesign project back in 2004. I was very excited to contribute CSS to a website that would get used by the W3C! Unfortunately, it decided to go a different direction and my work did not get used. However, it was still pretty exciting to have the opportunity, and I don\u2019t regret a moment of that work. I learned a lot about accessibility from this experience and it helped me land some of the jobs I\u2019ve had since.\n\nAlmost a decade later, I got super into Sass. One of the core maintainers, Chris Eppstein, lamented on Twitter one day that the Sass website and brand was in dire need of design help. That led to the creation of an open source task force, Team Sass Design, and we revived the brand and the website, which launched at SassConf in 2013.\n\nIt helped me in my current job. I showed it during my portfolio review when I interviewed for the role. Then I was able to use inspiration from a technique I\u2019d tried on the Sass website to help create the more feature-rich design system that my team at work is building. But most importantly, I soon learned that it is exhilarating to be a part of the Sass community. This is the biggest benefit of all. It feels really good to give back to the technology I love and use for getting my work done.\n\nBen Werdmuller writes about the need for design in open source. It\u2019s great to see designers contributing to open source in awesome ways. When A List Apart\u2019s website went open source, Anna Debenham contributed by helping build its pattern library. Bevan Stephens worked with FontForge on the design of its website. There are also designers who have created their own open source projects. There\u2019s Dan Cederholm\u2019s Pears, which shares common patterns in markup and style. There\u2019s also Brad Frost\u2019s Pattern Lab, which shares his famous method of atomic design and applies it to a design system. These systems and patterns have been used in real-world projects, such as RetailMeNot, so designers have contributed to the web in an even larger way simply by putting their work out there for others to use. That\u2019s kind of fun to think about.\n\nHow to get started\n\nSo are you stoked about getting into the open source community? That\u2019s great!\n\nInitially, you might get worried or uncomfortable in getting involved. That\u2019s okay. But first consider that the project is open source for a reason. Your contribution (no matter how large or small) can help in a big way.\n\nIf you find a project you\u2019re interested in helping, make sure you do your research. Sometimes project team members will be attached to their current design. Is there already a designer on the core team? Reach out to that designer first. Don\u2019t be too aggressive with why you think your design is better than theirs. Rather, offer some constructive feedback and a proposal of what would make the design better. Chances are, if the designer cares about the project, and you make a strong case, they\u2019ll be up for it.\n\nAre there contribution guidelines? It\u2019s proper etiquette to read these and follow the community\u2019s rules. You\u2019ll have a better chance of getting your work accepted, and it shows that you take the time to care and add to the overall quality of the project. Does the project lack guidelines? Consider starting a draft for that before getting started in the design.\n\nWhen contributing to open source, use your initiative to solve problems in a manageable way. Huge pull requests are hard to review and will often either get neglected or rejected. Work in small, modular, and iterative contributions.\n\nSo this is my personal take on what I\u2019ve learned from my experience and why I love open source. I\u2019d love to hear from you if you have your own experience in doing this and what you\u2019ve learned along the way as well. Please share in the comments!\n\nThanks Drew McLellan, Eric Suzanne, Kyle Neath for sharing their thoughts with me on this!", "year": "2014", "author": "Jina Anne", "author_slug": "jina", "published": "2014-12-19T00:00:00+00:00", "url": "https://24ways.org/2014/why-you-should-design-for-open-source/", "topic": "design"}
{"rowid": 250, "title": "Build up Your Leadership Toolbox", "contents": "Leadership. It can mean different things to different people and vary widely between companies. Leadership is more than just a job title. You won\u2019t wake up one day and magically be imbued with all you need to do a good job at leading. If we don\u2019t have a shared understanding of what a Good Leader looks like, how can we work on ourselves towards becoming one? How do you know if you even could be a leader? Can you be a leader without the title?\nWhat even is it?\nI got very frustrated way back in my days as a senior developer when I was given \u201cadvice\u201d about my leadership style; at the time I didn\u2019t have the words to describe the styles and ways in which I was leading to be able to push back. I heard these phrases a lot:\n\nyou need to step up\nyou need to take charge\nyou need to grab the bull by its horns\nyou need to have thicker skin\nyou need to just be more confident in your leading\nyou need to just make it happen\n\nI appreciate some people\u2019s intent was to help me, but honestly it did my head in. WAT?! What did any of this even mean. How exactly do you \u201cstep up\u201d and how are you evaluating what step I\u2019m on? I am confident, what does being even more confident help achieve with leading? Does that not lead you down the path of becoming an arrogant door knob? >___<\nWhile there is no One True Way to Lead, there is an overwhelming pattern of people in positions of leadership within tech industry being held by men. It felt a lot like what people were fundamentally telling me to do was to be more like an extroverted man. I was being asked to demonstrate more masculine associated qualities (#notallmen). I\u2019ll leave the gendered nature of leadership qualities as an exercise in googling for the reader.\nI\u2019ve never had a good manager and at the time had no one else to ask for help, so I turned to my trusted best friends. Books.\nI <3 books\nI refused to buy into that style of leadership as being the only accepted way to be. There had to be room for different kinds of people to be leaders and have different leadership styles.\nThere are three books that changed me forever in how I approach and think about leadership.\n\nPrimal leadership, by Daniel Goleman, Richard Boyatzis and Annie McKee\nQuiet, by Susan Cain\nDaring Greatly - How the Courage to be Vulnerable transforms the way we live, love, parent and Lead, by Bren\u00e9 Brown\n\nI recommend you read them. Ignore the slightly cheesy titles and trust me, just read them.\nPrimal leadership helped to give me the vocabulary and understanding I needed about the different styles of leadership there are, how and when to apply them.\nQuiet really helped me realise how much I was being undervalued and misunderstood in an extroverted world. If I\u2019d had managers or support from someone who valued introverts\u2019 strengths, things would\u2019ve been very different. I would\u2019ve had someone telling others to step down and shut up for a change rather than pushing on me to step up and talk louder over everyone else. It\u2019s OK to be different and needing different things like time to recharge or time to think before speaking. It also improved my ability to work alongside my more extroverted colleagues by giving me an understanding of their world so I could communicate my needs in a language they would get.\nBren\u00e9 Brown\u2019s book I am forever in debt to. Her work gave me the courage to stand up and be my own kind of leader. Even when no-one around me looked or sounded like me, I found my own voice.\nIt takes great courage to be vulnerable and open about what you can and can\u2019t do. Open about your mistakes. Vocalise what you don\u2019t know and asking for help. In some lights, these are seen as weaknesses and many have tried to use them against me, to pull me down and exclude me for talking about them. Dear reader, it did not work, they failed. The truth is, they are my greatest strengths. The privileges I have, I use for good as best and often as I can.\nJust like gender, leadership is not binary\nIf you google for what a leader is, you\u2019ll get many different answers. I personally think Bren\u00e9\u2019s version is the best as it is one that can apply to a wider range of people, irrespective of job title or function.\n\nI define a leader as anyone who takes responsibility for finding potential in people and processes, and who has the courage to develop that potential.\nBren\u00e9 Brown\n\nBeing a leader isn\u2019t about being the loudest in a room, having veto power, talking over people or ignoring everyone else\u2019s ideas. It\u2019s not about \u201ctelling people what to do\u201d. It\u2019s not about an elevated status that you\u2019re better than others. Nor is it about creating a hand wavey far away vision and forgetting to help support people in how to get there.\nBeing a Good Leader is about having a toolbox of leadership styles and skills to choose from depending on the situation. Knowing how and when to apply them is part of the challenge and difficulty in becoming good at it. It is something you will have to continuously work on, forever. There is no Done.\nLeaders are Made, they are not Born.\nBe flexible in your leadership style\n\nTypically, the best, most effective leaders act according to one or more of six distinct approaches to leadership and skillfully switch between the various styles depending on the situation.\n\nFrom the book, Primal Leadership, it gives a summary of 6 leadership styles which are:\n\nVisionary\nCoaching\nAffiliative\nDemocratic\nPacesetting\nCommanding\n\nVisionary, moves people toward a shared dream or future. When change requires a new vision or a clear direction is needed, using a visionary style of leadership helps communicate that picture. By learning how to effectively communicate a story you can help people to move in that direction and give them clarity on why they\u2019re doing what they\u2019re doing.\nCoaching, is about connecting what a person wants and helping to align that with organisation\u2019s goals. It\u2019s a balance of helping someone improve their performance to fulfil their role and their potential beyond.\nAffiliative, creates harmony by connecting people to each other and requires effective communication to aid facilitation of those connections. This style can be very impactful in healing rifts in a team or to help strengthen connections within and across teams. During stressful times having a positive and supportive connection to those around us really helps see us through those times.\nDemocratic, values people\u2019s input and gets commitment through participation. Taking this approach can help build buy-in or consensus and is a great way to get valuable input from people. The tricky part about this style, I find, is that when I gather and listen to everyone\u2019s input, that doesn\u2019t mean the end result is that I have to please everyone.\nThe next two, sadly, are the ones wielded far too often and have the greatest negative impact. It\u2019s where the \u201ctelling people what to do\u201d comes from. When used sparingly and in the right situations, they can be a force for good. However, they must not be your default style.\nPacesetting, when used well, it is about meeting challenging and exciting goals. When you need to get high-quality results from a motivated and well performing team, this can be great to help achieve real focus and drive. Sadly it is so overused and poorly executed it becomes the \u201cjust make it happen\u201d and driver of unrealistic workload which contributes to burnout.\nCommanding, when used appropriately soothes fears by giving clear direction in an emergency or crisis. When shit is on fire, you want to know that your leadership ability can help kick-start a turnaround and bring clarity. Then switch to another style. This approach is also required when dealing with problematic employees or unacceptable behaviour.\nCommanding style seems to be what a lot of people think being a leader is, taking control and commanding a situation. It should be used sparingly and only when absolutely necessary.\nBe responsible for the power you wield\nIf reading through those you find yourself feeling a bit guilty that maybe you overuse some of the styles, or overwhelmed that you haven\u2019t got all of these down and ready to use in your toolbox\u2026\nTake a breath. Take responsibility. Take action.\nNo one is perfect, and it\u2019s OK. You can start right now working on those. You can have a conversation with your team and try being open about how you\u2019re going to try some different styles. You can be vulnerable and own up to mistakes you might\u2019ve made followed with an apology. You can order those books and read them. Those books will give you more examples on those leadership styles and help you to find your own voice.\nThe impact you can have on the lives of those around you when you\u2019re a leader, is huge. You can help be that positive impact, help discover and develop potential in someone.\n\nTime spent understanding people is never wasted.\nCate Huston.\n\nI believe in you. <3 Mazz.", "year": "2018", "author": "Mazz Mosley", "author_slug": "mazzmosley", "published": "2018-12-10T00:00:00+00:00", "url": "https://24ways.org/2018/build-up-your-leadership-toolbox/", "topic": "business"}
{"rowid": 197, "title": "Designing for Mobile Performance", "contents": "Last year, some colleagues at Google ran a research study titled \u201cThe Need for Mobile Speed\u201d to find out what the impact of performance and perception of speed had on the way people use the web on their mobile devices. \nThat\u2019s not a trivial distinction; when considering performance, how fast something feels is often more important than how fast it actually is. When dealing with sometimes underpowered mobile devices and slow mobile networks, designing experiences that feel fast is exceptionally important.\nOne of the most startling numbers we found in the study was that 53% of mobile site visits are abandoned if pages take longer than 3 seconds to load.\nWe wanted to find out more, so following on from this study, we conducted research to define what the crucial elements of speed are. We took into consideration the user experience (UX), overall perception of speed, and how differing contexts the user finds themselves in can alter how fast a user thinks something loaded.\nTo understand speed and load times first we must understand that user mobile web behaviour is broken down into three buckets;\n\nIntention\nLocation\nState of mind\n\nLet\u2019s look at each of those in turn.\nIntention\nUsers browse sites on a mobile device for many different reasons. To be able to effectively design a performant user experience for them, it\u2019s important to understand what those reasons might be. When asked to describe their reason for visiting a site, approximately 30% of people asked by the study claimed that they were simply browsing without a particular purpose in mind. Looking deeper, we found that this number increased slightly (34%) for retail sites. 30% said they were just there to find out some information for a future task or action, such as booking a flight.\nInterestingly, the research shows that users are actually window shopping using their mobile browser. Only 29% actually said they had a specific goal or intent in mind, and this number increases significantly for financial services like banking sites (57%). This goes against a traditionally held view of users wanting to perform simple actions efficiently on their mobile device. Sure, some users are absolutely doing that, but many are just browsing around without a goal in mind, just like they would on a desktop browser.\nThis gives great insight into the user\u2019s intentions. It tells us that users are actively using sites on their mobile, but a large majority do not intend to do anything instantly. There\u2019s no goal they\u2019re under pressure to achieve. If a site\u2019s performance is lousy or janky, this will only reaffirm to the user to that they can hold off on completing a task, so they might just give up. \nHowever, if a site is quick to load, sophisticated in expressing its value proposition quickly, and enables the user to perform their actions seamlessly, then turning that \u201cbrowsing user\u201d into a \u201cbuying user\u201d becomes all that much easier. When the user has no goal, there\u2019s more opportunity to convert, and you stand a greater chance of doing that if the performance is good enough so they stick around.\nLocation\nObviously, mobile devices by their nature can be used in many different locations. This is an interesting consideration, because it\u2019s not something we traditionally need to take into account designing experiences for static platforms like desktop computers.\nThe in the study, we found that 82% of users browse the web on their mobile phone while in their home. In contrast, only 7% do the same while at work. This might come across as a bit of a shock, but when you look at mobile usage \u2013 in particular app usage \u2013 most of the apps being used are either a social network or some sort of entertainment or media app. Due to the unreliability of network connections, users will often alternate between these two types of apps.\nThe consequence being that if a site doesn\u2019t work offline, or otherwise compensate for bad network connectivity in some way by providing opportunities to allow users to browse their site, then it becomes a self-fulfilling prophecy as to why users mostly view the mobile web from the comfort of their homes where there is a strong WiFi connection. They\u2019re using mobile devices, but they\u2019re not actually mobile themselves.\nAnother thing to bear in mind is how users alternate between devices, a study by comScore found that 80% of transactions take place on desktop while 69% of the browsing takes place on mobile. Any given user might access from more than one location - they might visit one day from a bus queue on their phone, and then next day from a laptop at home.\nState of mind\nOne more thing we need to take into consideration is the user\u2019s state of mind. Whilst browsing at home, users tend to be more relaxed, and in the research 76% stated they were generally calmer at home. The user\u2019s state of mind can have quite a big impact on how they perceive things. The calmer they are, the quicker a site might appear to load. If the user is anxious and impatiently drumming their fingers on the table, things seem to take longer, and even a small wait can feel like an eternity.\nThis is quite key. Over 40% of sites take longer than 4 seconds to load for users who are are out and about and using a mobile data connection. Coupled with our perception, and amplified by a potentially less-than-calm state of mind, this can seem like an age.\nWhat does this all mean?\nI think we can all agree that users prefer strong, steady connections and comfort when completing transactions. It seems like common sense when we say it out loud. Recreating these feelings and sensations of comfort and predictability under all circumstances therefore becomes paramount. Equally, when asked in the study, users all claimed that speed was the most important factor impacting their mobile web usage. Over 40%, in fact, said it was the most important UX feature of a site, and nobody asked considered it to be of no importance at all.\n\nThe meaning of speed\nWhen it comes to performance, speed is measured in two ways \u2013 real speed; as measured on a clock, and perceived speed; how responsive an interaction feels.  We can, of course, improve how quickly a site loads by simply making files smaller. Even then, the study showed that 32% of users felt a site can feel slow even when it loads in less than 4 seconds. This gets even worse when you look at it by age group, with 50% if young people (18-24 year olds) thinking a site was slower than it actually was. When you add to the mix that users think a site loaded faster when they are sitting compared to when they are standing up, then you are in a world of trouble if your site doesn\u2019t have any clear indicators to let the user know the loading state of you website or app.\nSo what can we do about this to improve our designs?\nHow to fix / hack user perception\nThere are some golden rules of speed, the first thing is hacking response time. If a page takes more than 3 seconds to load, you will certainly start to lose your users. However, if that slowness is part of a UX flow such as processing information, the user understands it might take a little time. Under those circumstances, a load time of under 5 seconds is acceptable, but even then, you should take caution. Anything above 8 seconds and you are in very real danger of losing your audience completely.  \n\n\n\nLoad time\nUser impression\n\n\n\n\n200 ms\nFeels instant\n\n\n1 s\nFeels it is performing smoothly\n\n\n5 s\nPart of user flow\n\n\n8 s\nLose attention\n\n\n\nRemove the tap delay\nMobile browsers often use a 300-350ms delay between the triggering of the touchend and click events. This delay was added so the browser could determine if there was going to be a double-tap triggered or not, since double-tap is a common gesture used to zoom into text. This delay can have the side effect of making interactions feel laggy, and therefore giving the user the impression that the site is slow, even if it\u2019s their own browser causing the problem.\nFortunately there\u2019s a way to remove the delay. Add following in the <head> of your page, and the delay no longer takes effect:\n<meta name=\"viewport\" content=\"width=device-width\">\nYou can also use touch-action: manipulation in newer browsers to eliminate click delay. For old browsers, FastClick by FT Labs uses touch events to trigger clicks faster and remove the double-tap gesture.\nMake use of Skeleton Screens\nA skeleton layout is a wireframe version of your app that displays while content is being loaded. This demonstrates to the user that content is about to be loaded, giving the impression that something is happening more quickly than it really is. Consider also using a preloader UI as well, with a text label informing the user that the app is loading. One example would be to pulsate the wireframe content giving the app the feeling that it is alive and loading. This reassures the user that something is happening and helps prevent resubmissions or refreshes of your app. Razvan Caliman created a Codepen example of how to create this effect in purely CSS. \nOne thing to consider though, if data doesn\u2019t load then you might need to create a fallback 404 or error page to let the user know what happened.  \n\nExample by Owen-Campbell Moore\nResponsive Touch Feedback\nCarefully designing the process by which items load is one aspect of increasing the perceived speed of your page, but reassuring the user that an action they have taken is in process is another. At Google we use something called a Ripple, which is is animating dot that expands or ripples in order to confirm to the user that their input has been triggered. This happens immediately, expanding outward from the point of touch. This reaffirms to the user that their input has been received and is being acted on, even before the site has had a chance to process or respond to the action. From the user\u2019s point of view, they\u2019ve tapped and the page has responded immediately, so it feels really quick and satisfying.\nYou can mimic this same behavior using our Material Design Components Web GitHub repo.\n\nProgress bars\nThese UI elements have existed for a very long time, but research conducted by Chris Harrison and published in New Scientist found that the style of a progress bar can alter the perception of speed drastically. As a matter of fact, progress bars with ripples that animate towards the left appear like they are loading faster by at least 11% percent. So when including them in your site, take into consideration that ripples and progress bars that pulsate faster as they get to the end will make your sites seem quicker.\n\n    \n  \n  Faster Progress Bars: Manipulating Perceived Duration with Visual Augmentations\nNavigation\nThe speed with which a user can locate navigational items or call to actions adds to their perceived performance of a site. If the user\u2019s next action is quick to spot on the screen, they don\u2019t spend time hunting around the interface with their eyes and fingers. So no matter how quickly your code runs, hiding items behind a nav bar will make a site feel slower than it actually is. \nFacebook found that switching to using bottom navigation saw an increase in engagement, satisfaction, revenue, speed, and importantly, perception of speed. If the user sees the navigation items they\u2019re looking for quickly, the interaction feels fast. What\u2019s more, end-to-end task completion is quicker too, as the interface not only feels quicker, but actually measures quicker as well. Similar reactions were found with Spotify and Redbooth.\nLuke Wroblewski gave a talk last year in Ireland titled \u201cObvious Always Wins\u201d which he demonstrated through the work he did with Google+. Luke\u2019s message is that by making the core features of your app obvious to your user, you will see engagement go up. This again seems obvious, right? However, it is important to note that adding bottom navigation doesn\u2019t just mean a black bar at the bottom of your screen like some kind of performance magic bullet. The goal is to make the items clear to the user so they know what they need to be doing, and how you achieve that could be different from one interface to the next. Google keeps experimenting with different navigation styles, but finally settled with the below when they conducted user research and testing.\n\nConclusion\nBy utilizing a collection of UI patterns and speed optimisation techniques, you can improve not only the actual speed of a site, but the perception of how quickly a user thinks your site is loading. It is critical to remember that users will not always be using your site in a calm and relaxed manner and that even their age can impact how they will use or not use your site. By improving your site\u2019s stability, you increase the likelihood of positive user engagement and task completion.\nYou can learn more about techniques to hack user perception and improve user speed by taking a look at an E-Book we published with Awwwards.com called Speed Matters: Design for Mobile Performance.", "year": "2017", "author": "Mustafa Kurtuldu", "author_slug": "mustafakurtuldu", "published": "2017-12-18T00:00:00+00:00", "url": "https://24ways.org/2017/designing-for-mobile-performance/", "topic": "ux"}
{"rowid": 307, "title": "Get the Balance Right: Responsive Display Text", "contents": "Last year in 24 ways I urged you to Get Expressive with Your Typography. I made the case for grabbing your readers\u2019 attention by setting text at display sizes, that is to say big. You should consider very large text in the same way you might a hero image: a picture that creates an atmosphere and anchors your layout.\nWhen setting text to be read, it is best practice to choose body and subheading sizes from a pre-defined scale appropriate to the viewport dimensions. We set those sizes using rems, locking the text sizes together so they all scale according to the page default and your reader\u2019s preferences.  You can take the same approach with display text by choosing larger sizes from the same scale.\nHowever, display text, as defined by its purpose and relative size, is text to be seen first, and read second. In other words a picture of text. When it comes to pictures, you are likely to scale all scene-setting imagery - cover photos, hero images, and so on - relative to the viewport. Take the same approach with display text: lock the size and shape of the text to the screen or browser window.\nIntroducing viewport units\nWith CSS3 came a new set of units which are locked to the viewport. You can use these viewport units wherever you might otherwise use any other unit of length such as pixels, ems or percentage. There are four viewport units, and in each case a value of 1 is equal to 1% of either the viewport width or height as reported in reference1 pixels:\n\nvw - viewport width,\nvh - viewport height,\nvmin - viewport height or width, whichever is smaller\nvmax - viewport height or width, whichever is larger\n\nIn one fell swoop you can set the size of a display heading to be proportional to the screen or browser width, rather than choosing from a scale in a series of media queries. The following makes the heading font size 13% of the viewport width:\nh1 {\n    font-size: 13 vw;\n}\nSo for a selection of widths, the rendered font size would be:\nRendered font size (px)\nViewport width\n13\u202fvw\n320\n42\n768\n100\n1024\n133\n1280\n166\n1920\n250\n\nA problem with using vw in this manner is the difference in text block proportions between portrait and landscape devices. Because the font size is based on the viewport width, the text on a landscape display is far bigger than when rendered on the same device held in a portrait orientation. \nLandscape text is much bigger than portrait text when using vw units.\nThe proportions of the display text relative to the screen are so dissimilar that each orientation has its own different character, losing the inconsistency and considered design you would want when designing to make an impression.\nHowever if the text was the same size in both orientations, the visual effect would be much more consistent. This where vmin comes into its own. Set the font size using vmin and the size is now set as a proportion of the smallest side of the viewport, giving you a far more consistent rendering.\nh1 {\n    font-size: 13vmin;\n}\nLandscape text is consistent with portrait text when using vmin units.\nComparing vw and vmin renderings for various common screen dimensions, you can see how using vmin keeps the text size down to a usable magnitude:\nRendered font size (px)\nViewport\n13\u202fvw\n13\u202fvmin\n320 \u00d7 480\n42\n42\n414 \u00d7 736\n54\n54\n768 \u00d7 1024\n100\n100\n1024 \u00d7 768\n133\n100\n1280 \u00d7 720\n166\n94\n1366 \u00d7 768\n178\n100\n1440 \u00d7 900\n187\n117\n1680 \u00d7 1050\n218\n137\n1920 \u00d7 1080\n250\n140\n2560 \u00d7 1440\n333\n187\n\nHybrid font sizing\nUsing vertical media queries to set text in direct proportion to screen dimensions works well when sizing display text. In can be less desirable when sizing supporting text such as sub-headings, which you may not want to scale upwards at the same rate as the display text. For example, we can size a subheading using vmin so that it starts at 16 px on smaller screens and scales up in the same way as the main heading:\nh1 {\n    font-size: 13vmin;\n}\nh2 {\n    font-size: 5vmin;\n}\nUsing vmin alone for supporting text can scale it too quickly\nThe balance of display text to supporting text on the phone works well, but the subheading text on the tablet, even though it has been increased in line with the main heading, is starting to feel disproportionately large and a little clumsy. This problem becomes magnified on even bigger screens.\nA solution to this is use a hybrid method of sizing text2. We can use the CSS calc() function to calculate a font size simultaneously based on both rems and viewport units. For example:\nh2 {\n    font-size: calc(0.5rem + 2.5vmin);\n}\nFor a 320 px wide screen, the font size will be 16 px, calculated as follows:\n(0.5 \u00d7 16) + (320 \u00d7 0.025) = 8 + 8 = 16px\nFor a 768 px wide screen, the font size will be 27 px:\n(0.5 \u00d7 16) + (768 \u00d7 0.025) = 8 + 19 = 27px\nThis results in a more balanced subheading that doesn\u2019t take emphasis away from the main heading:\n\nTo give you an idea of the effect of using a hybrid approach, here\u2019s a side-by-side comparison of hybrid and viewport text sizing:\ntable.ex--scale{width:100%;overflow: hidden;} table.ex--scale td{vertical-align:baseline;text-align:center;padding:0} tr.ex--scale-key{color:#666} tr.ex--scale-key td{font-size:.875rem;padding:0 0.125em} .ex--scale-2 tr.ex--scale-size{color:#ccc} tr.ex--scale-size td{font-size:1em;line-height:.34em;padding-bottom:.5rem} td.ex--scale-step{color:#000} td.ex--scale-hilite{color:red} .ex--scale-3 tr.ex--scale-size td{line-height:.9em}\n\ntop: calc() hybrid method; bottom: vmin only\n16\n20\n27\n32\n35\n40\n44\n16\n24\n38\n48\n54\n64\n72\n320\n480\n768\n960\n1080\n1280\n1440\n\nOver this festive period, try experiment with the proportion of rem and vmin in your hybrid calculation to see what feels best for your particular setting.\n\n\n\n\nA reference pixel is based on the logical resolution of a device which takes into account double density screens such as Retina displays.\u00a0\u21a9\ufe0e\n\n\nFor even more sophisticated uses of hybrid text sizing see the work of Mike Riethmuller.\u00a0\u21a9\ufe0e", "year": "2016", "author": "Richard Rutter", "author_slug": "richardrutter", "published": "2016-12-09T00:00:00+00:00", "url": "https://24ways.org/2016/responsive-display-text/", "topic": "code"}
{"rowid": 234, "title": "An Introduction to CSS 3-D Transforms", "contents": "Ladies and gentlemen, it is the second decade of the third millennium and we are still kicking around the same 2-D interface we got three decades ago. Sure, Apple debuted a few apps for OSX 10.7 that have a couple more 3-D flourishes, and Microsoft has had that Flip 3D for a while. But c\u2019mon \u2013 2011 is right around the corner. That\u2019s Twenty Eleven, folks. Where is our 3-D virtual reality? By now, we should be zipping around the Metaverse on super-sonic motorbikes.\n\nGranted, the capability of rendering complex 3-D environments has been present for years. On the web, there are already several solutions: Flash; three.js in <canvas>; and, eventually, WebGL. Finally, we meagre front-end developers have our own three-dimensional jewel: CSS 3-D transforms!\n\nRationale\n\nLike a beautiful jewel, 3-D transforms can be dazzling, a true spectacle to behold. But before we start tacking 3-D diamonds and rubies to our compositions like Liberace\u2018s tailor, we owe it to our users to ask how they can benefit from this awesome feature. \n\nAn entire application should not take advantage of 3-D transforms. CSS was built to style documents, not generate explorable environments. I fail to find a benefit to completing a web form that can be accessed by swivelling my viewport to the Sign-Up Room (although there have been proposals to make the web just that). Nevertheless, there are plenty of opportunities to use 3-D transforms in between interactions with the interface, via transitions.\n\nTake, for instance, the Weather App on the iPhone. The application uses two views: a details view; and an options view. Switching between these two views is done with a 3-D flip transition. This informs the user that the interface has two \u2013 and only two \u2013 views, as they can exist only on either side of the same plane.\n\n Flipping from details view to options view via a 3-D transition\n\nAlso, consider slide shows. When you\u2019re looking at the last slide, what cues tip you off that advancing will restart the cycle at the first slide? A better paradigm might be achieved with a 3-D transform, placing the slides side-by-side in a circle (carousel) in three-dimensional space; in that arrangement, the last slide obviously comes before the first.\n\n3-D transforms are more than just eye candy. We can also use them to solve dilemmas and make our applications more intuitive. \n\nCurrent support\n\nThe CSS 3D Transforms module has been out in the wild for over a year now. Currently, only Safari supports the specification \u2013 which includes Safari on Mac OS X and Mobile Safari on iOS. \n\nThe support roadmap for other browsers varies. The Mozilla team has taken some initial steps towards implementing the module. Mike Taylor tells me that the Opera team is keeping a close eye on CSS transforms, and is waiting until the specification is fleshed out. And our best friend Internet Explorer still needs to catch up to 2-D transforms before we can talk about the 3-D variety.\n\nTo make matters more perplexing, Safari\u2019s WebKit cousin Chrome currently accepts 3-D transform declarations, but renders them in 2-D space. Chrome team member Paul Irish, says that 3-D transforms are on the horizon, perhaps in one of the next 8.0 releases.\n\nThis all adds up to a bit of a challenge for those of us excited by 3-D transforms. I\u2019ll give it to you straight: missing the dimension of depth can make degradation a bit ungraceful. Unless the transform is relatively simple and holds up in non-3D-supporting browsers, you\u2019ll most likely have to design another solution. But what\u2019s another hurdle in a steeplechase? We web folk have had our mettle tested for years. We\u2019re prepared to devise multiple solutions.\n\nHere\u2019s the part of the article where I mention Modernizr, and you brush over it because you\u2019ve read this part of an article hundreds of times before. But seriously, it\u2019s the best way to test for CSS 3-D transform support. Use it.\n\nEven with these difficulties mounting up, trying out 3-D transforms today is the right move. The CSS 3-D transforms module was developed by the same team at Apple that produced the CSS 2D Transforms and Animation modules. Both specifications have since been adopted by Mozilla and Opera. Transforming in three-dimensions now will guarantee you\u2019ll be ahead of the game when the other browsers catch up.\n\nThe choice is yours. You can make excuses and pooh-pooh 3-D transforms because they\u2019re too hard and only snobby Apple fans will see them today. Or, with a tip of the fedora to Mr Andy Clarke, you can get hard-boiled and start designing with the best features out there right this instant.\n\nSo, I bid you, in the words of the eternal Optimus Prime\u2026\n\n\n\tTransform and roll out.\n\n\nLet\u2019s get coding.\n\nPerspective\n\nTo activate 3-D space, an element needs perspective. This can be applied in two ways: using the transform property, with the perspective as a functional notation:\n\n-webkit-transform: perspective(600);\n\nor using the perspective property: \n\n-webkit-perspective: 600;\n\nSee example: Perspective 1.\n\n\n\n The red element on the left uses transform: perspective() functional notation; the blue element on the right uses the perspective property\n\n\n\nThese two formats both trigger a 3-D space, but there is a difference. The first, functional notation is convenient for directly applying a 3-D transform on a single element (in the previous example, I use it in conjunction with a rotateY transform). But when used on multiple elements, the transformed elements don\u2019t line up as expected. If you use the same transform across elements with different positions, each element will have its own vanishing point. To remedy this, use the perspective property on a parent element, so each child shares the same 3-D space.\n\nSee Example: Perspective 2.\n\n\n\n Each red box on the left has its own vanishing point within the parent container; the blue boxes on the right share the vanishing point of the parent container\n\n\n\nThe value of perspective determines the intensity of the 3-D effect. Think of it as a distance from the viewer to the object. The greater the value, the further the distance, so the less intense the visual effect. perspective: 2000; yields a subtle 3-D effect, as if we were viewing an object from far away. perspective: 100; produces a tremendous 3-D effect, like a tiny insect viewing a massive object.\n\nBy default, the vanishing point for a 3-D space is positioned at its centre. You can change the position of the vanishing point with perspective-origin property.\n\n-webkit-perspective-origin: 25% 75%;\n\nSee Example: Perspective 3.\n\n\n\n\n\n\n\n3-D transform functions\n\nAs a web designer, you\u2019re probably well acquainted with working in two dimensions, X and Y, positioning items horizontally and vertically. With a 3-D space initialised with perspective, we can now transform elements in all three glorious spatial dimensions, including the third Z dimension, depth. \n\n3-D transforms use the same transform property used for 2-D transforms. If you\u2019re familiar with 2-D transforms, you\u2019ll find the basic 3D transform functions fairly similar. \n\n\n\trotateX(angle)\n\trotateY(angle)\n\trotateZ(angle)\n\ttranslateZ(tz)\n\tscaleZ(sz)\n\n\nWhereas translateX() positions an element along the horizontal X-axis, translateZ() positions it along the Z-axis, which runs front to back in 3-D space. Positive values position the element closer to the viewer, negative values further away.\n\nThe rotate functions rotate the element around the corresponding axis. This is somewhat counter-intuitive at first, as you might imagine that rotateX will spin an object left to right. Instead, using rotateX(45deg) rotates an element around the horizontal X-axis, so the top of the element angles back and away, and the bottom gets closer to the viewer.\n\nSee Example: Transforms 1.\n\n\n\n3-D rotate() and translate() functions around each axis\n\n\n\nThere are also several shorthand transform functions that require values for all three dimensions:\n\n\n\ttranslate3d(tx,ty,tz)\n\tscale3d(sx,sy,sz)\n\trotate3d(rx,ry,rz,angle)\n\n\nPro-tip: These foo3d() transform functions also have the benefit of triggering hardware acceleration in Safari. Dean Jackson, CSS 3-D transform spec author and main WebKit dude, writes (to Thomas Fuchs):\n\n\n\tIn essence, any transform that has a 3D operation as one of its functions will trigger hardware compositing, even when the actual transform is 2D, or not doing anything at all (such as translate3d(0,0,0)). Note this is just current behaviour, and could change in the future (which is why we don\u2019t document or encourage it). But it is very helpful in some situations and can significantly improve redraw performance.\n\n\nFor the sake of simplicity, my demos will use the basic transform functions, but if you\u2019re writing production-ready CSS for iOS or Safari-only, make sure to use the foo3d() functions to get the best rendering performance.\n\nCard flip\n\nWe now have all the tools to start making 3-D objects. Let\u2019s get started with something simple: flipping a card.\n\nHere\u2019s the basic markup we\u2019ll need:\n\n<section class=\"container\">\n  <div id=\"card\">\n    <figure class=\"front\">1</figure>\n    <figure class=\"back\">2</figure>\n  </div>\n</section>\n\nThe .container will house the 3-D space. The #card acts as a wrapper for the 3-D object. Each face of the card has a separate element: .front; and .back. Even for such a simple object, I recommend using this same pattern for any 3-D transform. Keeping the 3-D space element and the object element(s) separate establishes a pattern that is simple to understand and easier to style.\n\nWe\u2019re ready for some 3-D stylin\u2019. First, apply the necessary perspective to the parent 3-D space, along with any size or positioning styles.\n\n.container { \n  width: 200px;\n  height: 260px;\n  position: relative;\n  -webkit-perspective: 800;\n}\n\nNow the #card element can be transformed in its parent\u2019s 3-D space. We\u2019re combining absolute and relative positioning so the 3-D object is removed from the flow of the document. We\u2019ll also add width: 100%;  and height: 100%;. This ensures the object\u2019s transform-origin will occur in the centre of .container. More on transform-origin later. \n\nLet\u2019s add a CSS3 transition so users can see the transform take effect. \n\n#card {\n  width: 100%;\n  height: 100%;\n  position: absolute;\n  -webkit-transform-style: preserve-3d;\n  -webkit-transition: -webkit-transform 1s;\n}\n\nThe .container\u2019s perspective only applies to direct descendant children, in this case #card. In order for subsequent children to inherit a parent\u2019s perspective, and live in the same 3-D space, the parent can pass along its perspective with transform-style: preserve-3d. Without 3-D transform-style, the faces of the card would be flattened with its parents and the back face\u2019s rotation would be nullified. \n\nTo position the faces in 3-D space, we\u2019ll need to reset their positions in 2-D with position: absolute. In order to hide the reverse sides of the faces when they are faced away from the viewer, we use backface-visibility: hidden. \n\n#card figure {\n  display: block;\n  position: absolute;\n  width: 100%;\n  height: 100%;\n  -webkit-backface-visibility: hidden;\n}\n\nTo flip the .back face, we add a basic 3-D transform of rotateY(180deg). \n\n#card .front {\n  background: red;\n}\n#card .back {\n  background: blue;\n  -webkit-transform: rotateY(180deg);\n}\n\nWith the faces in place, the #card requires a corresponding style for when it is flipped.\n\n#card.flipped {\n  -webkit-transform: rotateY(180deg);\n}\n\nNow we have a working 3-D object. To flip the card, we can toggle the flipped class. When .flipped, the #card will rotate 180 degrees, thus exposing the .back face.\n\nSee Example: Card 1.\n\n\n\nFlipping a card in three dimensions\n\n\n\nSlide-flip\n\nTake another look at the Weather App 3-D transition. You\u2019ll notice that it\u2019s not quite the same effect as our previous demo. If you follow the right edge of the card, you\u2019ll find that its corners stay within the container. Instead of pivoting from the horizontal centre, it pivots on that right edge. But the transition is not just a rotation \u2013 the edge moves horizontally from right to left. We can reproduce this transition just by modifying a couple of lines of CSS from our original card flip demo.\n\nThe pivot point for the rotation occurs at the right side of the card. By default, the transform-origin of an element is at its horizontal and vertical centre (50% 50% or center center). Let\u2019s change it to the right side:\n\n#card { -webkit-transform-origin: right center; }\n\nThat flip now needs some horizontal movement with translateX. We\u2019ll set the rotation to -180deg so it flips right side out.\n\n#card.flipped {\n  -webkit-transform: translateX(-100%) rotateY(-180deg);\n}\n\nSee Example: Card 2.\n\n\n\nCreating a slide-flip from the right edge of the card\n\n\n\nCube\n\nCreating 3-D card objects is a good way to get started with 3-D transforms. But once you\u2019ve mastered them, you\u2019ll be hungry to push it further and create some true 3-D objects: prisms. We\u2019ll start out by making a cube.\n\nThe markup for the cube is similar to the card. This time, however, we need six child elements for all six faces of the cube:\n\n<section class=\"container\">\n  <div id=\"cube\">\n    <figure class=\"front\">1</figure>\n    <figure class=\"back\">2</figure>\n    <figure class=\"right\">3</figure>\n    <figure class=\"left\">4</figure>\n    <figure class=\"top\">5</figure>\n    <figure class=\"bottom\">6</figure>\n  </div>\n</section>\n\nBasic position and size styles set the six faces on top of one another in the container.\n\n.container {\n  width: 200px;\n  height: 200px;\n  position: relative;\n  -webkit-perspective: 1000;\n}\n#cube {\n  width: 100%;\n  height: 100%;\n  position: absolute;\n  -webkit-transform-style: preserve-3d;\n}\n#cube figure {\n  width: 196px;\n  height: 196px;\n  display: block;\n  position: absolute;\n  border: 2px solid black;\n}\n\nWith the card, we only had to rotate its back face. The cube, however, requires that five of the six faces to be rotated. Faces 1 and 2 will be the front and back. Faces 3 and 4 will be the sides. Faces 5 and 6 will be the top and bottom.\n\n#cube .front { -webkit-transform: rotateY(0deg); }\n#cube .back { -webkit-transform: rotateX(180deg); }\n#cube .right { -webkit-transform: rotateY(90deg); }\n#cube .left { -webkit-transform: rotateY(-90deg); }\n#cube .top { -webkit-transform: rotateX(90deg); }\n#cube .bottom { -webkit-transform: rotateX(-90deg); }\n\nWe could remove the first #cube .front style declaration, as this transform has no effect, but let\u2019s leave it in to keep our code consistent.\n\nNow each face is rotated, and only the front face is visible. The four side faces are all perpendicular to the viewer, so they appear invisible. To push them out to their appropriate sides, they need to be translated out from the centre of their positions. Each side of the cube is 200 pixels wide. From the cube\u2019s centre they\u2019ll need to be translated out half that distance, 100px.\n\n#cube .front { -webkit-transform: rotateY(0deg) translateZ(100px); }\n#cube .back { -webkit-transform: rotateX(180deg) translateZ(100px); }\n#cube .right { -webkit-transform: rotateY(90deg) translateZ(100px); }\n#cube .left { -webkit-transform: rotateY(-90deg) translateZ(100px); }\n#cube .top { -webkit-transform: rotateX(90deg) translateZ(100px); }\n#cube .bottom { -webkit-transform: rotateX(-90deg) translateZ(100px); }\n\nNote here that the translateZ function comes after the rotate. The order of transform functions is important. Take a moment and soak this up. Each face is first rotated towards its position, then translated outward in a separate vector.\n\nWe have a working cube, but we\u2019re not done yet.\n\nReturning to the Z-axis origin\n\nFor the sake of our users, our 3-D transforms should not distort the interface when the active panel is at its resting position. But once we start pushing elements off their Z-axis origin, distortion is inevitable. \n\nIn order to keep 3-D transforms snappy, Safari composites the element, then applies the transform. Consequently, anti-aliasing on text will remain whatever it was before the transform was applied. When transformed forward in 3-D space, significant pixelation can occur. \n\nSee Example: Transforms 2.\n\n\n\n\n\n\n\nLooking back at the Perspective 3 demo, note that no matter how small the perspective value is, or wherever the transform-origin may be, the panel number 1 always returns to its original position, as if all those funky 3-D transforms didn\u2019t even matter.\n\nTo resolve the distortion and restore pixel perfection to our #cube, we can push the 3-D object back, so that the front face will be positioned back to the Z-axis origin.\n\n#cube { -webkit-transform: translateZ(-100px); }\n\nSee Example: Cube 1.\n\n\n\nRestoring the front face to the original position on the Z-axis\n\n\n\nRotating the cube\n\nTo expose any face of the cube, we\u2019ll need a style that rotates the cube to expose any face. The transform values are the opposite of those for the corresponding face. We toggle the necessary class on the #box to apply the appropriate transform.\n\n#cube.show-front { -webkit-transform: translateZ(-100px) rotateY(0deg); }\n#cube.show-back { -webkit-transform: translateZ(-100px) rotateX(-180deg); }\n#cube.show-right { -webkit-transform: translateZ(-100px) rotateY(-90deg); }\n#cube.show-left { -webkit-transform: translateZ(-100px) rotateY(90deg); }\n#cube.show-top { -webkit-transform: translateZ(-100px) rotateX(-90deg); }\n#cube.show-bottom { -webkit-transform: translateZ(-100px) rotateX(90deg); }\n\nNotice how the order of the transform functions has reversed. First, we push the object back with translateZ, then we rotate it.\n\nFinishing up, we can add a transition to animate the rotation between states. \n\n#cube { -webkit-transition: -webkit-transform 1s; }\n\nSee Example: Cube 2.\n\n\n\nRotating the cube with a CSS transition\n\n\n\nRectangular prism\n\nCubes are easy enough to generate, as we only have to worry about one measurement. But how would we handle a non-regular rectangular prism? Let\u2019s try to make one that\u2019s 300 pixels wide, 200 pixels high, and 100 pixels deep. \n\nThe markup remains the same as the #cube, but we\u2019ll switch the cube id for #box. The container styles remain mostly the same:\n\n.container {\n  width: 300px;\n  height: 200px;\n  position: relative;\n  -webkit-perspective: 1000;\n}\n#box {\n  width: 100%;\n  height: 100%;\n  position: absolute;\n  -webkit-transform-style: preserve-3d;\n}\n\nNow to position the faces. Each set of faces will need their own sizes. The smaller faces (left, right, top and bottom) need to be positioned in the centre of the container, where they can be easily rotated and then shifted outward. The thinner left and right faces get positioned left: 100px ((300\u2009\u2212\u2009100)\u2009\u00f7\u20092), The stouter top and bottom faces get positioned top: 50px ((200\u2009\u2212\u2009100)\u2009\u00f7\u20092).\n\n#box figure {\n  display: block;\n  position: absolute;\n  border: 2px solid black;\n}\n#box .front,\n#box .back {\n  width: 296px;\n  height: 196px;\n}\n#box .right,\n#box .left {\n  width: 96px;\n  height: 196px;\n  left: 100px;\n}\n#box .top,\n#box .bottom {\n  width: 296px;\n  height: 96px;\n  top: 50px;\n}\n\nThe rotate values can all remain the same as the cube example, but for this rectangular prism, the translate values do differ. The front and back faces are each shifted out 50 pixels since the #box is 100 pixels deep. The translate value for the left and right faces is 150 pixels for their 300 pixels width. Top and bottom panels take 100 pixels for their 200 pixels height:\n\n#box .front { -webkit-transform: rotateY(0deg) translateZ(50px); }\n#box .back { -webkit-transform: rotateX(180deg) translateZ(50px); }\n#box .right { -webkit-transform: rotateY(90deg) translateZ(150px); }\n#box .left { -webkit-transform: rotateY(-90deg) translateZ(150px); }\n#box .top { -webkit-transform: rotateX(90deg) translateZ(100px); }\n#box .bottom { -webkit-transform: rotateX(-90deg) translateZ(100px); }\n\nSee Example: Box 1.\n\n\n\n\n\n\n\nJust like the cube example, to expose a face, the #box needs to have a style to reverse that face\u2019s transform. Both the translateZ and rotate values are the opposites of the corresponding face.\n\n#box.show-front { -webkit-transform: translateZ(-50px) rotateY(0deg); }\n#box.show-back { -webkit-transform: translateZ(-50px) rotateX(-180deg); }\n#box.show-right { -webkit-transform: translateZ(-150px) rotateY(-90deg); }\n#box.show-left { -webkit-transform: translateZ(-150px) rotateY(90deg); }\n#box.show-top { -webkit-transform: translateZ(-100px) rotateX(-90deg); }\n#box.show-bottom { -webkit-transform: translateZ(-100px) rotateX(90deg); }\n\nSee Example: Box 2.\n\n\n\nRotating the rectangular box with a CSS transition\n\n\n\nCarousel\n\nFront-end developers have a myriad of choices when it comes to content carousels. Now that we have 3-D capabilities in our browsers, why not take a shot at creating an actual 3-D carousel?\n\nThe markup for this demo takes the same form as the box, cube and card. Let\u2019s make it interesting and have a carousel with nine panels.\n\n<div class=\"container\">\n  <div id=\"carousel\">\n    <figure>1</figure>\n    <figure>2</figure>\n    <figure>3</figure>\n    <figure>4</figure>\n    <figure>5</figure>\n    <figure>6</figure>\n    <figure>7</figure>\n    <figure>8</figure>\n    <figure>9</figure>\n  </div>\n</div>\n\nNow, apply basic layout styles. Let\u2019s give each panel of the #carousel 20 pixel gaps between one another, done here with left: 10px; and top: 10px;. The effective width of each panel is 210 pixels.\n\n.container {\n  width: 210px;\n  height: 140px;\n  position: relative;\n  -webkit-perspective: 1000;\n}\n#carousel {\n  width: 100%;\n  height: 100%;\n  position: absolute;\n  -webkit-transform-style: preserve-3d;\n}\n#carousel figure {\n  display: block;\n  position: absolute;\n  width: 186px;\n  height: 116px;\n  left: 10px;\n  top: 10px;\n  border: 2px solid black;\n}\n\nNext up: rotating the faces. This #carousel has nine panels. If each panel gets an equal distribution on the carousel, each panel would be rotated forty degrees from its neighbour (360\u2009\u00f7\u20099).\n\n#carousel figure:nth-child(1) { -webkit-transform: rotateY(0deg); }\n#carousel figure:nth-child(2) { -webkit-transform: rotateY(40deg); }\n#carousel figure:nth-child(3) { -webkit-transform: rotateY(80deg); }\n#carousel figure:nth-child(4) { -webkit-transform: rotateY(120deg); }\n#carousel figure:nth-child(5) { -webkit-transform: rotateY(160deg); }\n#carousel figure:nth-child(6) { -webkit-transform: rotateY(200deg); }\n#carousel figure:nth-child(7) { -webkit-transform: rotateY(240deg); }\n#carousel figure:nth-child(8) { -webkit-transform: rotateY(280deg); }\n#carousel figure:nth-child(9) { -webkit-transform: rotateY(320deg); }\n\nNow, the outward shift. Back when we were creating the cube and box, the translate value was simple to calculate, as it was equal to one half the width, height or depth of the object. With this carousel, there is no size we can automatically use as a reference. We\u2019ll have to calculate the distance of the shift by other means.\n\n\n\nDrawing a diagram of the carousel, we can see that we know only two things: the width of each panel is 210 pixels; and the each panel is rotated forty degrees from the next. If we split one of these segments down its centre, we get a right-angled triangle, perfect for some trigonometry.\n\nWe can determine the length of r in this diagram with a basic tangent equation:\n\n\n\nThere you have it: the panels need to be translated 288 pixels in 3-D space. \n\n#carousel figure:nth-child(1) { -webkit-transform: rotateY(0deg) translateZ(288px); }\n#carousel figure:nth-child(2) { -webkit-transform: rotateY(40deg) translateZ(288px); }\n#carousel figure:nth-child(3) { -webkit-transform: rotateY(80deg) translateZ(288px); }\n#carousel figure:nth-child(4) { -webkit-transform: rotateY(120deg) translateZ(288px); }\n#carousel figure:nth-child(5) { -webkit-transform: rotateY(160deg) translateZ(288px); }\n#carousel figure:nth-child(6) { -webkit-transform: rotateY(200deg) translateZ(288px); }\n#carousel figure:nth-child(7) { -webkit-transform: rotateY(240deg) translateZ(288px); }\n#carousel figure:nth-child(8) { -webkit-transform: rotateY(280deg) translateZ(288px); }\n#carousel figure:nth-child(9) { -webkit-transform: rotateY(320deg) translateZ(288px); }\n\nIf we decide to change the width of the panel or the number of panels, we only need to plug in those two variables into our equation to get the appropriate translateZ value. In JavaScript terms, that equation would be:\n\nvar tz = Math.round( ( panelSize / 2 ) / \n  Math.tan( ( ( Math.PI * 2 ) / numberOfPanels ) / 2 ) );\n// or simplified to\nvar tz = Math.round( ( panelSize / 2 ) / \n  Math.tan( Math.PI / numberOfPanels ) );\n\nJust like our previous 3-D objects, to show any one panel we need only apply the reverse transform on the carousel. Here\u2019s the style to show the fifth panel:\n\n-webkit-transform: translateZ(-288px) rotateY(-160deg);\n\nSee Example: Carousel 1.\n\n\n\n\n\n\n\nBy now, you probably have two thoughts: \n\n\n\tRewriting transform styles for each panel looks tedious.\n\tWhy bother doing high school maths? Aren\u2019t robots supposed to be doing all this work for us?\n\n\nAnd you\u2019re absolutely right. The repetitive nature of 3-D objects lends itself to scripting. We can offload all the monotonous transform styles to our dynamic script, which, if done correctly, will be more flexible than the hard-coded version.\n\nSee Example: Carousel 2.\n\nConclusion\n\n3-D transforms change the way we think about the blank canvas of web design. Better yet, they change the canvas itself, trading in the flat surface for voluminous depth.\n\nMy hope is that you took at least one peak at a demo and were intrigued. We web designers, who have rejoiced for border-radius, box-shadow and background gradients, now have an incredible tool at our disposal in 3-D transforms. They deserve just the same enthusiasm, research and experimentation we have seen on other CSS3 features. Now is the perfect time to take the plunge and start thinking about how to use three dimensions to elevate our craft. I\u2019m breathless waiting for what\u2019s to come. \n\nSee you on the flip side.", "year": "2010", "author": "David DeSandro", "author_slug": "daviddesandro", "published": "2010-12-14T00:00:00+00:00", "url": "https://24ways.org/2010/intro-to-css-3d-transforms/", "topic": "code"}
{"rowid": 63, "title": "Be Fluid with Your Design Skills: Build Your Own Sites", "contents": "Just five years ago in 2010, when we were all busy trying to surprise and delight, learning CSS3 and trying to get whole websites onto one page, we had a poster on our studio wall. It was entitled \u2018Designers Vs Developers\u2019, an infographic that showed us the differences between the men(!) who created websites. \nDesigners wore skinny jeans and used Macs and developers wore cargo pants and brought their own keyboards to work. We began to learn that designers and developers were not only doing completely different jobs but were completely different people in every way. This opinion was backed up by hundreds of memes, millions of tweets and pages of articles which used words like void and battle and versus.\nThankfully, things move quickly in this industry; the wide world of web design has moved on in the last five years. There are new devices, technologies, tools \u2013 and even a few women. Designers have been helped along by great apps, software, open source projects, conferences, and a community of people who, to my unending pride, love to share their knowledge and their work.\nSo the world has moved on, and if Miley Cyrus, Ruby Rose and Eliot Sumner are identifying as gender fluid (an identity which refers to a gender which varies over time or is a combination of identities), then I would like to come out as discipline fluid! \nOK, I will probably never identify as a developer, but I will identify as fluid! How can we be anything else in an industry that moves so quickly? That\u2019s how we should think of our skills, our interests and even our job titles. After all, Steve Jobs told us that \u201cDesign is not just what it looks like and feels like. Design is how it works.\u201d Sorry skinny-jean-wearing designers \u2013 this means we\u2019re all designing something together. And it\u2019s not just about knowing the right words to use: you have to know how it feels. How it feels when you make something work, when you fix that bug, when you make it work on IE.\nLike anything in life, things run smoothly when you make the effort to share experiences, empathise and deeply understand the needs of others. How can designers do that if they\u2019ve never built their own site? I\u2019m not talking the big stuff, I\u2019m talking about your portfolio site, your mate\u2019s business website, a website for that great idea you\u2019ve had. I\u2019m talking about doing it yourself to get an unique insight into how it feels.\nWe all know that designers and developers alike love an <ol>, so here it is.\nTen reasons designers should be fluid with their skills and build their own sites\n1. It\u2019s never been easier\nNow here\u2019s where the definition of \u2018build\u2019 is going to get a bit loose and people are going to get angry, but when I say it\u2019s never been easier I mean because of the existence of apps and software like WordPress, Squarespace, Tumblr, et al. It\u2019s easy to make something and get it out there into the world, and these are all gateway drugs to hard coding!\n2. You\u2019ll understand how it feels\nHow it feels to be so proud that something actually works that you momentarily don\u2019t notice if the kerning is off or the padding is inconsistent. How it feels to see your site appear when you\u2019ve redirected a URL. How it feels when you just can\u2019t work out where that one extra space is in a line of PHP that has killed your whole site.\n3. It makes you a designer\nNot a better designer, it makes you a designer when you are designing how things look and how they work. \n4. You learn about movement\nPhotoshop and Sketch just don\u2019t cut it yet. Until you see your site in a browser or your app on a phone, it\u2019s hard to imagine how it moves. Building your own sites shows you that it\u2019s not just about how the content looks on the screen, but how it moves, interacts and feels.\n5. You make techie friends\nAll the tutorials and forums in the world can\u2019t beat your network of techie friends. Since I started working in web design I have worked with, sat next to, and co-created with some of the greatest developers. Developers who\u2019ve shared their knowledge, encouraged me to build things, patiently explained HTML, CSS, servers, divs, web fonts, iOS development. There has been no void, no versus, very few battles; just people who share an interest and love of making things.  \n6. You will own domain names\nWhen something is paid for, online and searchable then it\u2019s real and you\u2019ve got to put the work in. Buying domains has taught me how to stop procrastinating, but also about DNS, FTP, email, and how servers work.\n7. People will ask you to do things\u2028\nLearning about code and development opens a whole new world of design. When you put your own personal websites and projects out there people ask you to do more things. OK, so sometimes those things are \u201cMake me a website for free\u201d, but more often it\u2019s cool things like \u201cCome and speak at my conference\u201d, \u201cWrite an article for my magazine\u201d and \u201cCollaborate with me.\u201d\n8. The young people are coming!\nThey love typography, they love print, they love layout, but they\u2019ve known how to put a website together since they started their first blog aged five and they show me clever apps they\u2019ve knocked together over the weekend! They\u2019re new, they\u2019re fluid, and they\u2019re better than us!\n9. Your portfolio is your portfolio\nOK, it\u2019s an obvious one, but as designers our work is our CV, our legacy! We need to show our skill, our attention to detail and our creativity in the way we showcase our work. Building your portfolio is the best way to start building your own websites. (And please be that designer who\u2019s bothered to work out how to change the Squarespace favicon!) \n10. It keeps you fluid!\nBuilding your own websites is tough. You\u2019ll never be happy with it, you\u2019ll constantly be updating it to keep up with technology and fashion, and by the time you\u2019ve finished it you\u2019ll want to start all over again. Perfect for forcing you to stay up-to-date with what\u2019s going on in the industry.\n</ol>", "year": "2015", "author": "Ros Horner", "author_slug": "roshorner", "published": "2015-12-12T00:00:00+00:00", "url": "https://24ways.org/2015/be-fluid-with-your-design-skills-build-your-own-sites/", "topic": "code"}
{"rowid": 11, "title": "JavaScript: Taking Off the Training Wheels", "contents": "JavaScript is the third pillar of front-end web development. Of those pillars, it is both the most powerful and the most complex, so it\u2019s understandable that when 24 ways asked, \u201cWhat one thing do you wish you had more time to learn about?\u201d, a number of you answered \u201cJavaScript!\u201d\n\nThis article aims to help you feel happy writing JavaScript, and maybe even without libraries like jQuery. I can\u2019t comprehensively explain JavaScript itself without writing a book, but I hope this serves as a springboard from which you can jump to other great resources.\n\nWhy learn JavaScript?\n\nSo what\u2019s in it for you? Why take the next step and learn the fundamentals?\n\nConfidence with jQuery\n\nIf nothing else, learning JavaScript will improve your jQuery code; you\u2019ll be comfortable writing jQuery from scratch and feel happy bending others\u2019 code to your own purposes. Writing efficient, fast and bug-free jQuery is also made much easier when you have a good appreciation of JavaScript, because you can look at what jQuery is really doing. Understanding how JavaScript works lets you write better jQuery because you know what it\u2019s doing behind the scenes. When you need to leave the beaten track, you can do so with confidence.\n\nIn fact, you could say that jQuery\u2019s ultimate goal is not to exist: it was invented at a time when web APIs were very inconsistent and hard to work with. That\u2019s slowly changing as new APIs are introduced, and hopefully there will come a time when jQuery isn\u2019t needed.\n\nAn example of one such change is the introduction of the very useful document.querySelectorAll. Like jQuery, it converts a CSS selector into a list of matching elements. Here\u2019s a comparison of some jQuery code and the equivalent without.\n\n$('.counter').each(function (index) {\n  $(this).text(index + 1);\n});\n\nvar counters = document.querySelectorAll('.counter');\n[].slice.call(counters).forEach(function (elem, index) {\n  elem.textContent = index + 1;\n});\n\nSolving problems no one else has!\n\nWhen you have to go to the internet to solve a problem, you\u2019re forever stuck reusing code other people wrote to solve a slightly different problem to your own. Learning JavaScript will allow you to solve problems in your own way, and begin to do things nobody else ever has.\n\nNode.js\n\nNode.js is a non-browser environment for running JavaScript, and it can do just about anything! But if that sounds daunting, don\u2019t worry: the Node community is thriving, very friendly and willing to help.\n\nI think Node is incredibly exciting. It enables you, with one language, to build complete websites with complex and feature-filled front- and back-ends. Projects that let users log in or need a database are within your grasp, and Node has a great ecosystem of library authors to help you build incredible things. Exciting!\n\nHere\u2019s an example web server written with Node. http is a module that allows you to create servers and, like jQuery\u2019s $.ajax, make requests. It\u2019s a small amount of code to do something complex and, while working with Node is different from writing front-end code, it\u2019s certainly not out of your reach.\n\nvar http = require('http');\nhttp.createServer(function (req, res) {\n  res.writeHead(200, {'Content-Type': 'text/plain'});\n  res.end('Hello World');\n}).listen(1337);\nconsole.log('Server running at http://localhost:1337/');\n\nGrunt and other website tools\n\nNode has brought in something of a renaissance in tools that run in the command line, like Yeoman and Grunt. Both of these rely heavily on Node, and I\u2019ll talk a little bit about Grunt here.\n\nGrunt is a task runner, and many people use it for compiling Sass or compressing their site\u2019s JavaScript and images. It\u2019s pretty cool. You configure Grunt via the gruntfile.js, so JavaScript skills will come in handy, and since Grunt supports plug-ins built with JavaScript, knowing it unlocks the bucketloads of power Grunt has to offer.\n\nWays to improve your skills\n\nSo you know you want to learn JavaScript, but what are some good ways to learn and improve? I think the answer to that is different for different people, but here are some ideas.\n\nRebuild a jQuery app\n\nConverting a jQuery project to non-jQuery code is a great way to explore how you modify elements on the page and make requests to the server for data. My advice is to focus on making it work in one modern browser initially, and then go cross-browser if you\u2019re feeling adventurous. There are many resources for directly comparing jQuery and non-jQuery code, like Jeffrey Way\u2019s jQuery to JavaScript article.\n\nFind a mentor\n\nIf you think you\u2019d work better on a one-to-one basis then finding yourself a mentor could be a brilliant way to learn. The JavaScript community is very friendly and many people will be more than happy to give you their time. I\u2019d look out for someone who\u2019s active and friendly on Twitter, and does the kind of work you\u2019d like to do. Introduce yourself over Twitter or send them an email. I wouldn\u2019t expect a full tutoring course (although that is another option!) but they\u2019ll be very glad to answer a question and any follow-ups every now and then.\n\nGo to a workshop\n\nMany conferences and local meet-ups run workshops, hosted by experts in a particular field. See if there\u2019s one in your area. Workshops are great because you can ask direct questions, and you\u2019re in an environment where others are learning just like you are \u2014 no need to learn alone!\n\nSet yourself challenges\n\nThis is one way I like to learn new things. I have a new thing that I\u2019m not very good at, so I pick something that I think is just out of my reach and I try to build it. It\u2019s learning by doing and, even if you fail, it can be enormously valuable.\n\nWhere to start?\n\nIf you\u2019ve decided learning JavaScript is an important step for you, your next question may well be where to go from here.\n\nI\u2019ve collected some links to resources I know of or use, with some discussion about why you might want to check a particular site out. I hope this serves as a springboard for you to go out and learn as much as you want.\n\nBeginner\n\nIf you\u2019re just getting started with JavaScript, I\u2019d recommend heading to one of these places. They cover the basics and, in some cases, a little more advanced stuff. They\u2019re all reputable sources (although, I\u2019ve included something I wrote \u2014 you can decide about that one!) and will not lead you astray.\n\n\n\tjQuery\u2019s JavaScript 101 is a great first resource for JavaScript that will give you everything you need to work with jQuery like a pro.\n\tCodecademy\u2019s JavaScript Track is a small but useful JavaScript course. If you like learning interactively, this could be one for you.\n\tHTMLDog\u2019s JavaScript Tutorials take you right through from the basics of code to a brief introduction to newer technology like Node and Angular. [Disclaimer: I wrote this stuff, so it comes with a hazard warning!]\n\tThe tuts+ jQuery to JavaScript mentioned earlier is great for seeing how jQuery code looks when converted to pure JavaScript.\n\n\nGetting in-depth\n\nFor more comprehensive documentation and help I\u2019d recommend adding these places to your list of go-tos.\n\n\n\tMDN: the Mozilla Developer Network is the first place I go for many JavaScript questions. I mostly find myself there via a search, but it\u2019s a great place to just go and browse.\n\tAxel Rauschmayer\u2019s 2ality is a stunning collection of articles that will take you deep into JavaScript. It\u2019s certainly worth looking at.\n\tAddy Osmani\u2019s JavaScript Design Patterns is a comprehensive collection of patterns for writing high quality JavaScript, particularly as you (I hope) start to write bigger and more complex applications.\n\n\nAnd finally\u2026\n\nI think the key to learning anything is curiosity and perseverance. If you have a question, go out and search for the answer, even if you have no idea where to start. Keep going and going and eventually you\u2019ll get there. I bet you\u2019ll learn a whole lot along the way. Good luck!\n\nMany thanks to the people who gave me their time when I was working on this article: Tom Oakley, Jack Franklin, Ben Howdle and Laura Kalbag.", "year": "2013", "author": "Tom Ashworth", "author_slug": "tomashworth", "published": "2013-12-05T00:00:00+00:00", "url": "https://24ways.org/2013/javascript-taking-off-the-training-wheels/", "topic": "code"}
{"rowid": 326, "title": "Don't be eval()", "contents": "JavaScript is an interpreted language, and like so many of its peers it includes the all powerful eval() function. eval() takes a string and executes it as if it were regular JavaScript code. It\u2019s incredibly powerful and incredibly easy to abuse in ways that make your code slower and harder to maintain. As a general rule, if you\u2019re using eval() there\u2019s probably something wrong with your design.\n\nCommon mistakes\n\nHere\u2019s the classic misuse of eval(). You have a JavaScript object, foo, and you want to access a property on it \u2013 but you don\u2019t know the name of the property until runtime. Here\u2019s how NOT to do it:\n\nvar property = 'bar';\nvar value = eval('foo.' + property);\n\nYes it will work, but every time that piece of code runs JavaScript will have to kick back in to interpreter mode, slowing down your app. It\u2019s also dirt ugly.\n\nHere\u2019s the right way of doing the above:\n\nvar property = 'bar';\nvar value = foo[property];\n\nIn JavaScript, square brackets act as an alternative to lookups using a dot. The only difference is that square bracket syntax expects a string.\n\nSecurity issues\n\nIn any programming language you should be extremely cautious of executing code from an untrusted source. The same is true for JavaScript \u2013 you should be extremely cautious of running eval() against any code that may have been tampered with \u2013 for example, strings taken from the page query string. Executing untrusted code can leave you vulnerable to cross-site scripting attacks.\n\nWhat\u2019s it good for?\n\nSome programmers say that eval() is B.A.D. \u2013 Broken As Designed \u2013 and should be removed from the language. However, there are some places in which it can dramatically simplify your code. A great example is for use with XMLHttpRequest, a component of the set of tools more popularly known as Ajax. XMLHttpRequest lets you make a call back to the server from JavaScript without refreshing the whole page. A simple way of using this is to have the server return JavaScript code which is then passed to eval(). Here is a simple function for doing exactly that \u2013 it takes the URL to some JavaScript code (or a server-side script that produces JavaScript) and loads and executes that code using XMLHttpRequest and eval().\n\nfunction evalRequest(url) {\n     var xmlhttp = new XMLHttpRequest();\n     xmlhttp.onreadystatechange = function() {\n          if (xmlhttp.readyState==4 && xmlhttp.status==200) {\n               eval(xmlhttp.responseText);\n          }\n     }\n     xmlhttp.open(\"GET\", url, true);\n     xmlhttp.send(null);\n }\n\nIf you want this to work with Internet Explorer you\u2019ll need to include this compatibility patch.", "year": "2005", "author": "Simon Willison", "author_slug": "simonwillison", "published": "2005-12-07T00:00:00+00:00", "url": "https://24ways.org/2005/dont-be-eval/", "topic": "code"}
{"rowid": 37, "title": "JavaScript Modules the ES6 Way", "contents": "JavaScript admittedly has plenty of flaws, but one of the largest and most prominent is the lack of a module system: a way to split up your application into a series of smaller files that can depend on each other to function correctly. \n\nThis is something nearly all other languages come with out of the box, whether it be Ruby\u2019s require, Python\u2019s import, or any other language you\u2019re familiar with. Even CSS has @import! JavaScript has nothing of that sort, and this has caused problems for  application developers as they go from working with small websites to full client-side applications. Let\u2019s be clear: it doesn\u2019t mean the new module system in the upcoming version of JavaScript won\u2019t be useful to you if you\u2019re building smaller websites rather than the next Instagram.\n\nThankfully, the lack of a module system will soon be a problem of the past. The next version of JavaScript, ECMAScript 6, will bring with it a full-featured module and dependency management solution for JavaScript. The bad news is that it won\u2019t be landing in browsers for a while yet \u2013 but the good news is that the specification for the module system and how it will look has been finalised. The even better news is that there are tools available to get it all working in browsers today without too much hassle. In this post I\u2019d like to give you the gift of JS modules and show you the syntax, and how to use them in browsers today. It\u2019s much simpler than you might think.\n\nWhat is ES6?\n\nECMAScript is a scripting language that is standardised by a company called Ecma International. JavaScript is an implementation of ECMAScript. ECMAScript 6 is simply the next version of the ECMAScript standard and, hence, the next version of JavaScript. The spec aims to be fully comfirmed and complete by the end of 2014, with a target initial release date of June 2015. It\u2019s impossible to know when we will have full feature support across the most popular browsers, but already some ES6 features are landing in the latest builds of Chrome and Firefox. You shouldn\u2019t expect to be able to use the new features across browsers without some form of additional tooling or library for a while yet.\n\nThe ES6 module spec\n\nThe ES6 module spec was fully confirmed in July 2014, so all the syntax I will show you in this article is not expected to change. I\u2019ll first show you the syntax and the new APIs being added to the language, and then look at how to use them today. There are two parts to the new module system. The first is the syntax for declaring modules and dependencies in your JS files, and the second is a programmatic API for loading in modules manually. The first is what most people are expected to use most of the time, so it\u2019s what I\u2019ll focus on more.\n\nModule syntax\n\nThe key thing to understand here is that modules have two key components. First, they have dependencies. These are things that the module you are writing depends on to function correctly. For example, if you were building a carousel module that used jQuery, you would say that jQuery is a dependency of your carousel. You import these dependencies into your module, and we\u2019ll see how to do that in a minute. Second, modules have exports. These are the functions or variables that your module exposes publicly to anything that imports it. Using jQuery as the example again, you could say that jQuery exports the $ function. Modules that depend on and hence import jQuery get access to the $ function, because jQuery exports it.\n\nAnother important thing to note is that when I discuss a module, all I really mean is a JavaScript file. There\u2019s no extra syntax to use other than the new ES6 syntax. Once ES6 lands, modules and files will be analogous.\n\nNamed exports\n\nModules can export multiple objects, which can be either plain old variables or JavaScript functions. You denote something to be exported with the export keyword:\n\nexport function double(x) {\n  return x + x;\n};\n\n\nYou can also store something in a variable then export it. If you do that, you have to wrap the variable in a set of curly braces.\n\nvar double = function(x) {\n  return x + x;\n}\n\nexport { double };\n\nA module can then import the double function like so:\n\nimport { double } from 'mymodule';\ndouble(2); // 4\n\nAgain, curly braces are required around the variable you would like to import. It\u2019s also important to note that from 'mymodule' will look for a file called mymodule.js in the same directory as the file you are requesting the import from. There is no need to add the .js extension.\n\nThe reason for those extra braces is that this syntax lets you export multiple variables:\n\nvar double = function(x) {\n  return x + x;\n}\n\nvar square = function(x) {\n  return x * x;\n}\n\nexport { double, square }\n\nI personally prefer this syntax over the export function \u2026, but only because it makes it much clearer to me what the module exports. Typically I will have my export {\u2026} line at the bottom of the file, which means I can quickly look in one place to determine what the module is exporting.\n\nA file importing both double and square can do so in just the way you\u2019d expect:\n\nimport { double, square } from 'mymodule';\ndouble(2); // 4\nsquare(3); // 9\n\nWith this approach you can\u2019t easily import an entire module and all its methods. This is by design \u2013 it\u2019s much better and you\u2019re encouraged to import just the functions you need to use.\n\nDefault exports\n\nAlong with named exports, the system also lets a module have a default export. This is useful when you are working with a large library such as jQuery, Underscore, Backbone and others, and just want to import the entire library. A module can define its default export (it can only ever have one default export) like so:\n\nexport default function(x) {\n  return x + x;\n}\n\nAnd that can be imported:\n\nimport double from 'mymodule';\ndouble(2); // 4\n\n\nThis time you do not use the curly braces around the name of the object you are importing. Also notice how you can name the import whatever you\u2019d like. Default exports are not named, so you can import them as anything you like:\n\nimport christmas from 'mymodule';\nchristmas(2); // 4\n\nThe above is entirely valid.\n\nAlthough it\u2019s not something that is used too often, a module can have both named exports and a default export, if you wish.\n\nOne of the design goals of the ES6 modules spec was to favour default exports. There are many reasons behind this, and there is a very detailed discussion on the ES Discuss site about it. That said, if you find yourself preferring named exports, that\u2019s fine, and you shouldn\u2019t change that to meet the preferences of those designing the spec.\n\nProgrammatic API\n\nAlong with the syntax above, there is also a new API being added to the language so you can programmatically import modules. It\u2019s pretty rare you would use this, but one obvious example is loading a module conditionally based on some variable or property. You could easily import a polyfill, for example, if the user\u2019s browser didn\u2019t support a feature your app relied on. An example of doing this is:\n\nif(someFeatureNotSupported) {\n  System.import('my-polyfill').then(function(myPolyFill) {\n    // use the module from here\n  });\n}\n\nSystem.import will return a promise, which, if you\u2019re not familiar, you can read about in this excellent article on HTMl5 Rocks by Jake Archibald. A promise basically lets you attach callback functions that are run when the asynchronous operation (in this case, System.import), is complete.\n\nThis programmatic API opens up a lot of possibilities and will also provide hooks to allow you to register callbacks that will run at certain points in the lifetime of a module. Those hooks and that syntax are slightly less set in stone, but when they are confirmed they will provide really useful functionality. For example, you could write code that would run every module that you import through something like JSHint before importing it. In development that would provide you with an easy way to keep your code quality high without having to run a command line watch task.\n\nHow to use it today\n\nIt\u2019s all well and good having this new syntax, but right now it won\u2019t work in any browser \u2013 and it\u2019s not likely to for a long time. Maybe in next year\u2019s 24 ways there will be an article on how you can use ES6 modules with no extra work in the browser, but for now we\u2019re stuck with a bit of extra work.\n\nES6 module transpiler\n\nOne solution is to use the ES6 module transpiler, a compiler that lets you write your JavaScript using the ES6 module syntax (actually a subset of it \u2013 not quite everything is supported, but the main features are) and have it compiled into either CommonJS-style code (CommonJS is the module specification that NodeJS and Browserify use), or into AMD-style code (the spec RequireJS uses). There are also plugins for all the popular build tools, including Grunt and Gulp.\n\nThe advantage of using this transpiler is that if you are already using a tool like RequireJS or Browserify, you can drop the transpiler in, start writing in ES6 and not worry about any additional work to make the code work in the browser, because you should already have that set up already. If you don\u2019t have any system in place for handling modules in the browser, using the transpiler doesn\u2019t really make sense. Remember, all this does is convert ES6 module code into CommonJS- or AMD-compliant JavaScript. It doesn\u2019t do anything to help you get that code running in the browser, but if you have that part sorted it\u2019s a really nice addition to your workflow. If you would like a tutorial on how to do this, I wrote a post back in June 2014 on using ES6 with the ES6 module transpiler.\n\nSystemJS\n\nAnother solution is SystemJS. It\u2019s the best solution in my opinion, particularly if you are starting a new project from scratch, or want to use ES6 modules on a project where you have no current module system in place. SystemJS is a spec-compliant universal module loader: it loads ES6 modules, AMD modules, CommonJS modules, as well as modules that just add a variable to the global scope (window, in the browser).\n\nTo load in ES6 files, SystemJS also depends on two other libraries: the ES6 module loader polyfill; and Traceur. Traceur is best accessed through the bower-traceur package, as the main repository doesn\u2019t have an easy to find downloadable version. The ES6 module load polyfill implements System.import, and lets you load in files using it. Traceur is an ES6-to-ES5 module loader. It takes code written in ES6, the newest version of JavaScript, and transpiles it into ES5, the version of JavaScript widely implemented in browsers. The advantage of this is that you can play with the new features of the language today, even though they are not supported in browsers. The drawback is that you have to run all your files through Traceur every time you save them, but this is easily automated. Additionally, if you use SystemJS, the Traceur compilation is done automatically for you.\n\nAll you need to do to get SystemJS running is to add a <script> element to load SystemJS into your webpage. It will then automatically load the ES6 module loader and Traceur files when it needs them. In your HTML you then need to use System.import to load in your module:\n\n<script>\n  System.import('./app');\n</script>\n\nWhen you load the page, app.js will be asynchronously loaded. Within app.js, you can now use ES6 modules. SystemJS will detect that the file is an ES6 file, automatically load Traceur, and compile the file into ES5 so that it works in the browser. It does all this dynamically in the browser, but there are tools to bundle your application in production, so it doesn\u2019t make a lot of requests on the live site. In development though, it makes for a really nice workflow.\n\nWhen working with SystemJS and modules in general, the best approach is to have a main module (in our case app.js) that is the main entry point for your application. app.js should then be responsible for loading all your application\u2019s modules. This forces you to keep your application organised by only loading one file initially, and having the rest dealt with by that file.\n\nSystemJS also provides a workflow for bundling your application together into one file.\n\nConclusion\n\nES6 modules may be at least six months to a year away (if not more) but that doesn\u2019t mean they can\u2019t be used today. Although there is an overhead to using them now \u2013 with the work required to set up SystemJS, the module transpiler, or another solution \u2013 that doesn\u2019t mean it\u2019s not worthwhile. Using any module system in the browser, whether that be RequireJS, Browserify or another alternative, requires extra tooling and libraries to support it, and I would argue that the effort to set up SystemJS is no greater than that required to configure any other tool. It also comes with the extra benefit that when the syntax is supported in browsers, you get a free upgrade. You\u2019ll be able to remove SystemJS and have everything continue to work, backed by the native browser solution.\n\nIf you are starting a new project, I would strongly advocate using ES6 modules. It is a syntax and specification that is not going away at all, and will soon be supported in browsers. Investing time in learning it now will pay off hugely further down the road.\n\nFurther reading\n\nIf you\u2019d like to delve further into ES6 modules (or ES6 generally) and using them today, I recommend the following resources:\n\n\n\tECMAScript 6 modules: the final syntax by Axel Rauschmayer\n\tPractical Workflows for ES6 Modules by Guy Bedford\n\tECMAScript 6 resources for the curious JavaScripter by Addy Osmani\n\tTracking ES6 support by Addy Osmani\n\tES6 Tools List by Addy Osmani\n\tUsing Grunt and the ES6 Module Transpiler by Thomas Boyt\n\tJavaScript Modules and Dependencies with jspm by myself\n\tUsing ES6 Modules Today by Guy Bedford", "year": "2014", "author": "Jack Franklin", "author_slug": "jackfranklin", "published": "2014-12-03T00:00:00+00:00", "url": "https://24ways.org/2014/javascript-modules-the-es6-way/", "topic": "code"}

In addition to my work as a design consultant, I\u2019ve worked as an educator, leading the Interaction Design team at Belfast School of Art, for the last 15 years.\nIn July, 2018 \u2013 frustrated with formal education, not least the ever-present hand of \u2018austerity\u2019 that has ravaged universities in the UK for almost a decade \u2013 I formally reduced my teaching commitment, moving from a full-time role to a half-time role.\nMaking the move from a (healthy!) monthly salary towards a position as a freelance consultant is not without its challenges: one month your salary\u2019s arriving in your bank account (and promptly disappearing to pay all of your bills); the next month, that salary\u2019s been drastically reduced. That can be a shock to the system.\nIn this article, I\u2019ll explore the challenges encountered when taking a life-changing leap of faith. To help you confront \u2018the fear\u2019 \u2013 the nervousness, the sleepless nights and the ever-present worry about paying the bills \u2013 I\u2019ll provide a set of tools that will enable you to take a leap of faith and pursue what deep down drives you.\nIn short: I\u2019ll bare my soul and share everything I\u2019m currently working on to \u2013 once and for all \u2013 make a final bid for freedom.\nThis isn\u2019t easy. I\u2019m sharing my innermost hopes and aspirations, and I might open myself up to ridicule, but I believe that by doing so, I might help others, by providing them with tools to help them make their own leap of faith.\nThe power of visualisation\nAs designers we have skills that we use day in, day out to imagine future possibilities, which we then give form. In our day-to-day work, we use those abilities to design products and services, but I also believe we can use those skills to design something every bit as important: ourselves.\nIn this article I\u2019ll explore three tools that you can use to design your future:\n\nProduct DNA\nArtefacts From the Future\nTomorrow Clients\n\nEach of these tools is designed to help you visualise your future. By giving that future form, and providing a concrete goal to aim for, you put the pieces in place to make that future a reality.\nBrian Eno \u2013 the noted musician, producer and thinker \u2013 states, \u201cHumans are capable of a unique trick: creating realities by first imagining them, by experiencing them in their minds.\u201d Eno helpfully provides a powerful example:\n\nWhen Martin Luther King said, \u201cI have a dream,\u201d he was inviting others to dream that dream with him. Once a dream becomes shared in that way, current reality gets measured against it and then modified towards it.\nThe dream becomes an invisible force which pulls us  forward. By this process it starts to come true. The act of imagining something makes it real.\n\nWhen you imagine your future \u2013 designing an alternate, imagined reality in your mind \u2013 you begin the process of making that future real.\nProduct DNA\nThe first tool, which I use regularly \u2013 for myself and for client work \u2013 is a tool called Product DNA. The intention of this tool is to identify beacons from which you can learn, helping you to visualise your future.\nWe all have heroes \u2013 individuals or organisations \u2013 that we look up to. Ask yourself, \u201cWho are your heroes?\u201d If you had to pick three, who would they be and what could you learn from them? (You probably have more than three, but distilling down to three is an exercise in itself.)\nEarlier this year, when I was putting the pieces in place for a change in career direction, I started with my heroes. I chose three individuals that inspired me:\n\nAlan Moore: the author of \u2018Do Design: Why Beauty is Key to Everything\u2019;\nMark Shayler: the founder of Ape, a strategic consultancy; and\nSeth Godin: a writer and educator I\u2019ve admired and followed for many years.\n\nLooking at each of these individuals, I \u2018borrowed\u2019 a little DNA from each of them. That DNA helped me to paint a picture of the kind of work I wanted to do and the direction I wanted to travel.\n\nMoore\u2019s book - \u2018Do Design\u2019 \u2013 had a powerful influence on me, but the primary inspiration I drew from him was the sense of gravitas he conveyed in his work. Moore\u2019s mission is an important one and he conveys that with an appropriate weight of expression.\nShayler\u2019s work appealed to me for its focus on equipping big businesses with a startup mindset. As he puts it: \u201cI believe that you can do the things that you do better.\u201d That sense \u2013 of helping others to be their best selves \u2013 appealed to me.\nFinally, the words Godin uses to describe himself \u2013 \u201cAn Author, Entrepreneur and Most of All, a Teacher\u201d \u2013 resonated with me. The way he positions himself, as, \u201cmost of all, a teacher,\u201d gave me the belief I needed that I could work as an educator, but beyond the ivory tower of academia.\nI\u2019ve been exploring each of these individuals in depth, learning from them and applying what I learn to my practice. They don\u2019t all know it, but they are all \u2018mentors from afar\u2019.\nIn a moment of serendipity \u2013 and largely, I believe, because I\u2019d used this tool to explore his work \u2013 I was recently invited by Alan Moore to help him develop a leadership programme built around his book.\nThe key lesson here is that not only has this exercise helped me to design my future and give it tangible form, it\u2019s also led to a fantastic opportunity to work with Alan Moore, a thinker who I respect greatly.\nArtefacts From the Future\nThe second tool, which I also use regularly, is a tool called \u2018Artefacts From the Future\u2019. These artefacts \u2013 especially when designed as \u2018finished\u2019 pieces \u2013 are useful for creating provocations to help you see the future more clearly.\n\u2018Artefacts From the Future\u2019 can take many forms: they might be imagined magazine articles, news items, or other manifestations of success. By imagining these end points and giving them form, you clarify your goals, establishing something concrete to aim for.\nEarlier this year I revisited this tool to create a provocation for myself. I\u2019d just finished Alla Kholmatova\u2019s excellent book on \u2018Design Systems\u2019, which I would recommend highly. The book wasn\u2019t just filled with valuable insights, it was also beautifully designed.\nOnce I\u2019d finished reading Kholmatova\u2019s book, I started thinking: \u201cPerhaps it\u2019s time for me to write a new book?\u201d Using the magic of \u2018Inspect Element\u2019, I created a fictitious page for a new book I wanted to write: \u2018Designing Delightful Experiences\u2019.\nI wrote a description for the book, considering how I\u2019d pitch it.\n\nThis imagined page was just what I needed to paint a picture in my mind of a possible new book. I contacted the team at Smashing Magazine and pitched the idea to them. I\u2019m happy to say that I\u2019m now working on that book, which is due to be published in 2019.\nWithout this fictional promotional page from the future, the book would have remained as an idea \u2013 loosely defined \u2013 rolling around my mind. By spending some time, turning that idea into something \u2018real\u2019, I had everything I needed to tell the story of the book, sharing it with the publishing team at Smashing Magazine.\nOf course, they could have politely informed me that they weren\u2019t interested, but I\u2019d have lost nothing \u2013 truly \u2013 in the process.\nAs designers, creating these imaginary \u2018Artefacts From the Future\u2019 is firmly within our grasp. All we need to do is let go a little and allow our imaginations to wander.\nIn my experience, working with clients and \u2013 to a lesser extent, students \u2013 it\u2019s the \u2018letting go\u2019 part that\u2019s the hard part. It can be difficult to let down your guard and share a weighty goal, but I\u2019d encourage you to do so. At the end of the day, you have nothing to lose.\nThe key lesson here is that your \u2018Artefacts From the Future\u2019 will focus your mind. They\u2019ll transform your unformed ideas into \u2018tangible evidence\u2019 of future possibilities, which you can use as discussion points and provocations, helping you to shape your future reality.\nTomorrow Clients\nThe third tool, which I developed more recently, is a tool called \u2018Tomorrow Clients\u2019. This tool is designed to help you identify a list of clients that you aspire to work with.\nThe goal is to pinpoint who you would like to work with \u2013 in an ideal world \u2013 and define how you\u2019d position yourself to win them over. Again, this involves \u2018letting go\u2019 and allowing your mind to imagine the possibilities, asking, \u201cWhat if\u2026?\u201d\nBefore I embarked upon the design of my new website, I put together a \u2018soul searching\u2019 document that acted as a focal point for my thinking. I contacted a number of designers for a second opinion to see if my thinking was sound.\nOne of my graduates \u2013 Chris Armstrong, the founder of Niice \u2013 replied with the following: \u201cMight it be useful to consider five to ten companies you\u2019d love to work for, and consider how you\u2019d pitch yourself to them?\u201d\nThis was just the provocation I needed. To add a little focus, I reduced the list to three, asking: \u201cWho would my top three clients be?\u201d\n\nBy distilling the list down I focused on who I\u2019d like to work for and how I\u2019d position myself to entice them to work with me. My list included: IDEO, Adobe and IBM. All are companies I admire and I believed each would be interesting to work for.\nThis exercise might \u2013 on the surface \u2013 appear a little like indulging in fantasy, but I believe it helps you to clarify exactly what it is you are good at and, just as importantly, put that in to words.\nFor each company, I wrote a short pitch outlining why I admired them and what I thought I could add to their already existing skillset.\nFocusing first on Adobe, I suggested establishing an emphasis on educational resources, designed to help those using Adobe\u2019s creative tools to get the most out of them.\nA few weeks ago, I signed a contract with the team working on Adobe XD to create a series of \u2018capsule courses\u2019, focused on UX design. The first of these courses \u2013 exploring UI design \u2013 will be out in 2019.\nI believe that Armstrong\u2019s provocation \u2013 asking me to shift my focus from clients I have worked for in the past to clients I aspire to work for in the future \u2013 made all the difference.\nThe key lesson here is that this exercise encouraged me to raise the bar and look to the future, not the past. In short, it enabled me to proactively design my future.\nIn closing\u2026\nI hope these three tools will prove a welcome addition to your toolset. I use them when working with clients, I also use them when working with myself.\nI passionately believe that you can design your future. I also firmly believe that you\u2019re more likely to make that future a reality if you put some thought into defining what it looks like.\nAs I say to my students and the clients I work with: It\u2019s not enough to want to be a success, the word \u2018success\u2019 is too vague to be a destination. A far better approach is to define exactly what success looks like.\nThe secret is to visualise your future in as much detail as possible. With that future vision in hand as a map, you give yourself something tangible to translate into a reality.", "year": "2018", "author": "Christopher Murphy", "author_slug": "christophermurphy", "published": "2018-12-15T00:00:00+00:00", "url": "https://24ways.org/2018/designing-your-future/", "topic": "process"}
{"rowid": 281, "title": "Nine Things I've Learned", "contents": "I\u2019ve been a professional graphic designer for fourteen years and for just under four of those a professional web designer. Like most designers I\u2019ve learned a lot in my time, both from a design point of view and in business as freelance designer. A few of the things I\u2019ve learned stick out in my mind, so I thought I\u2019d share them with you. They\u2019re pretty random and in no particular order.\n\n1. Becoming the designer you want to be\n\nWhen I started out as a young graphic designer, I wanted to design posters and record sleeves, pretty much like every other young graphic designer. The problem is that the reality of the world means that when you get your first job you\u2019re designing the back of a paracetamol packet or something equally weird. I recently saw a tweet that went something like this: \u201cYou\u2019ll never become the designer you always dreamt of being by doing the work you never wanted to do\u201d. This is so true; to become the designer you want to be, you need to be designing the things you\u2019re passionate about designing. This probably this means working in the evenings and weekends for little or no money, but it\u2019s time well spent. Doing this will build up your portfolio with the work that really shows what you can do! Soon, someone will ask you to design something based on having seen this work. From this point, you\u2019re carving your own path in the direction of becoming the designer you always wanted to be.\n\n2. Compete on your own terms\n\nAs well as all being friends, we are also competitors. In order to win new work we need a selling point, preferably a unique selling point. Web design is a combination of design disciplines \u2013 user experience design, user interface Design, visual design, development, and so on. Some companies will sell themselves as UX specialists, which is fine, but everyone who designs a website from scratch does some sort of UX, so it\u2019s not really a unique selling point. Of course, some people do it better than others.\n\nOne area of web design that clients have a strong opinion on, and will judge you by, is visual design. It\u2019s an area in which it\u2019s definitely possible to have a unique selling point. Designing the visual aesthetic for a website is a combination of logical decision making and a certain amount of personal style. If you can create a unique visual style to your work, it can become a selling point that\u2019s unique to you.\n\n3. How much to charge and staying motivated\n\nWhen you\u2019re a freelance designer one of the hardest things to do is put a price on your work and skills. Finding the right amount to charge is a fine balance between supplying value to your customer and also charging enough to stay motivated to do a great job. It\u2019s always tempting to offer a low price to win work, but it\u2019s often not the best approach: not just for yourself but for the client as well.\n\nA client once asked me if I could reduce my fee by \u00a31,000 and still be motivated enough to do a good job. In this case the answer was yes, but it was the question that resonated with me. I realized I could use this as a gauge to help me price projects. Before I send out a quote I now always ask myself the question \u201cIs the amount I\u2019ve quoted enough to make me feel motivated to do my best on this project?\u201d I never send out a quote unless the answer is yes. In my mind there\u2019s no point in doing any project half-heartedly, as every project is an opportunity to build your reputation and expand your portfolio to show potential clients what you can do. Offering a client a good price but not being prepared to put everything you have into it, isn\u2019t value for money.  \n\n4. Supplying the right design\n\nWhen I started out as a graphic designer it seemed to be the done thing to supply clients with a ton of options for their logo or brochure designs. In a talk given by Dan Rubin, he mentioned that this was a legacy of agencies competing with each other in a bid to create the illusion of offering more value for money. Over the years, I\u2019ve realized that offering more than one solution makes no sense. The reason a client comes to you as a designer is because you\u2019re the person than can get it right. If I  were to supply three options, I\u2019d be knowingly offering my client at least two options that I didn\u2019t think worked.\n\nTo this day I still get asked how many homepage design options I\u2019ll supply for the quoted amount. The answer is one. Of course, I\u2019m more than happy to iterate upon the design to fine-tune it and, on the odd occasion, I do revisit a design concept if I just didn\u2019t nail the design first time around. Your time is much better spent refining the right design option than rushing out three substandard designs in the same amount of time.\n\n5. Colour is key\n\nThere are many contributing factors that go into making a good visual design, but one of the simplest ways to do this is through the use of colour. The colour palette used in a design can have such a profound effect on a visual design that it almost feels like you\u2019re cheating. It\u2019s easy to add more and more subtle shades of colour to add a sense of sophistication and complexity to a design, but it dilutes the overall visual impact. When I design, I almost have a rule that only allows me to use a very limited colour palette. I don\u2019t always stick to it, but it\u2019s always in mind and something I\u2019m constantly reviewing through my design process.\n\n6. Creative thinking is central to good or boundary-pushing web design\n\nWhen we think of creativity in web design we often link this to the visual design, as there is an obvious opportunity to be creative in this area if the brief allows it. Something that I\u2019ve learnt in my time as a web designer is that there\u2019s a massive need for creative thinking in the more technical aspects of web design. The tools we use for building websites are there to be manipulated and used in creative ways to design exciting and engaging user experiences. Great developers are constantly using their creativity to push the boundaries of what can be done with CSS, jQuery and JavaScript. \n\nBeing creative and creative thinking are things we should embrace as an industry and they are qualities that can be found in anyone, whether they be a visual designer or Rails developer.\n\n7. Creative block: don\u2019t be afraid to get things wrong\n\nCreative block can be a killer when designing. It\u2019s often applied to visual design, which is more subjective. I suffer from creative block on a regular basis. It\u2019s hugely frustrating and can screw up your schedule. Having thought about what creative block actually is, I\u2019ve come to the conclusion that it\u2019s actually more of a lack of direction than a lack of ideas. You have ideas and solutions in mind but don\u2019t feel committed to any of them. You\u2019re scared that whatever direction you take, it\u2019ll turn out to be wrong. I\u2019ve found that the best remedy for this is to work through this barrier. It\u2019s a bit like designing with a blindfold on \u2013 you don\u2019t really know where you\u2019re going. If you stick to your guns and keep pressing forward I find that, nine times out of ten, this process leads to a solution. As the page begins to fill, the direction you\u2019re looking for slowly begins to take shape.\n\n8. You get better at designing by designing\n\nI often get emails asking me what books someone can read to help them become a better designer. There are a lot of good books on subjects like HTML5, CSS, responsive web design and the like, that will really help improve anyone\u2019s web design skills. But, when it comes to visual design, the best way to get better is to design as much as possible. You can\u2019t follow instructions for these things because design isn\u2019t following instructions. A large part of web design is definitely applying a set of widely held conventions, but there\u2019s another part to it that is invention and the only way to get better at this is to do it as much as possible.\n\n9. Self-belief is overrated\n\nThroughout our lives we\u2019re told to have self-belief. Self-belief and confidence in what we do, whatever that may be. The problem is that some people find it easier than others to believe in themselves. I\u2019ve spent years trying to convince myself to believe in what I do but have always found it difficult to have complete confidence in my design skills. Self-doubt always creeps in.\n\nI\u2019ve realized that it\u2019s ok to doubt myself and I think it might even be a good thing!  I\u2019ve realized that it\u2019s my self-doubt that propels me forward and makes me work harder to achieve the best results. The reason I\u2019m sharing this is because I know I\u2019m not the only designer that feels this way. You can spend a lot of time fighting self-doubt only to discover that it\u2019s your body\u2019s natural mechanism to help you do the best job possible.", "year": "2011", "author": "Mike Kus", "author_slug": "mikekus", "published": "2011-12-11T00:00:00+00:00", "url": "https://24ways.org/2011/nine-things-ive-learned/", "topic": "business"}
{"rowid": 193, "title": "Web Content Accessibility Guidelines\u2014for People Who Haven't Read Them", "contents": "I\u2019ve been a huge fan of the Web Content Accessibility Guidelines 2.0 since the World Wide Web Consortium (W3C) published them, nine years ago. I\u2019ve found them practical and future-proof, and I\u2019ve found that they can save a huge amount of time for designers and developers. You can apply them to anything that you can open in a browser. My favourite part is when I use the guidelines to make a website accessible, and then attend user-testing and see someone with a disability easily using that website.\nToday, the United Nations International Day of Persons with Disabilities, seems like a good time to re-read Laura Kalbag\u2019s explanation of why we should bother with accessibility. That should motivate you to devour this article.\nIf you haven\u2019t read the Web Content Accessibility Guidelines 2.0, you might find them a bit off-putting at first. The editors needed to create a single standard that countries around the world could refer to in legislation, and so some of the language in the guidelines reads like legalese. The editors also needed to future-proof the guidelines, and so some terminology\u2014such as \u201ctime-based media\u201d and \u201cprogrammatically determined\u201d\u2014can sound ambiguous. The guidelines can seem lengthy, too: printing the guidelines, the Understanding WCAG 2.0 document, and the Techniques for WCAG 2.0 document would take 1,200 printed pages.\nThis festive season, let\u2019s rip off that legalese and ambiguous terminology like wrapping paper, and see\u2014in a single article\u2014what gifts the Web Content Accessibility Guidelines 2.0 editors have bestowed upon us.\nCan your users perceive the information on your website?\nThe first guideline has criteria that help you prevent your users from asking \u201cWhat the **** is this thing here supposed to be?\u201d\n1.1.1 Text is the most accessible format for information. Screen readers\u2014such as the \u201cVoiceOver\u201d setting on your iPhone or the \u201cTalkBack\u201d app on your Android phone\u2014understand text better than any other format. The same applies for other assistive technology, such as translation apps and Braille displays. So, if you have anything on your webpage that\u2019s not text, you must add some text that gives your user the same information. You probably know how to do this already; for example:\n\nfor images in webpages, put some alternative text in an alt attribute to tell your user what the image conveys to the user;\nfor photos in tweets, add a description to make the images accessible;\nfor Instagram posts, write a caption that conveys the photo\u2019s information.\n\nThe alternative text should allow the user to get the same information as someone who can see the image. For websites that have too many images for someone to add alternative text to, consider how machine learning and Dynamically Generated Alt Text might\u2014might\u2014be appropriate.\nYou can probably think of a few exceptions where providing text to describe an image might not make sense. Remember I described these guidelines as \u201cpractical\u201d? They cover all those exceptions:\n\nUser interface controls such as buttons and text inputs must have names or labels to tell your user what they do.\nIf your webpage has video or audio (more about these later on!), you must\u2014at least\u2014have text to tell the user what they are.\nMaybe your webpage has a test where your user has to answer a question about an image or some audio, and alternative text would give away the answer. In that case, just describe the test in text so your users know what it is.\nIf your webpage features a work of art, tell your user the experience it evokes.\nIf you have to include a Captcha on your webpage\u2014and please avoid Captchas if at all possible, because some users cannot get past them\u2014you must include text to tell your user what it is, and make sure that it doesn\u2019t rely on only one sense, such as vision.\nIf you\u2019ve included something just as decoration, you must make sure that your user\u2019s assistive technology can ignore it. Again, you probably know how to do this. For example, you could use CSS instead of HTML to include decorative images, or you could add an empty alt attribute to the img element. (Please avoid that recent trend where developers add empty alt attributes to all images in a webpage just to make the HTML validate. You\u2019re better than that.)\n\n(Notice that the guidelines allow you to choose how to conform to them, with whatever technology you choose. To make your website conform to a guideline, you can either choose one of the techniques for WCAG 2.0 for that guideline or come up with your own. Choosing a tried-and-tested technique usually saves time!)\n1.2.1 If your website includes a podcast episode, speech, lecture, or any other recorded audio without video, you must include a transcription or some other text to give your user the same information. In a lot of cases, you might find this easier than you expect: professional transcription services can prove relatively inexpensive and fast, and sometimes a speaker or lecturer can provide the speech or lecture notes that they read out word-for-word. Just make sure that all your users can get the same information and the same results, whether they can hear the audio or not. For example, David Smith and Marco Arment always publish episode transcripts for their Under the Radar podcast. \nSimilarly, if your website includes recorded video without audio\u2014such as an animation or a promotional video\u2014you must either use text to detail what happens in the video or include an audio version. Again, this might work out easier then you perhaps fear: for example, you could check to see whether the animation started life as a list of instructions, or whether the promotional video conveys the same information as the \u201cAbout Us\u201d webpage. You want to make sure that all your users can get the same information and the same results, whether they can see that video or not.\n1.2.2 If your website includes recorded videos with audio, you must add captions to those videos for users who can\u2019t hear the audio. Professional transcription services can provide you with time-stamped text in caption formats that YouTube supports, such as .srt and .sbv. You can upload those to YouTube, so captions appear on your videos there. YouTube can auto-generate captions, but the quality varies from impressively accurate to comically inaccurate. If you have a text version of what the people in the video said\u2014such as the speech that a politician read or the bedtime story that an actor read\u2014you can create a transcript file in .txt format, without timestamps. YouTube then creates captions for your video by synchronising that text to the audio in the video. If you host your own videos, you can ask a professional transcription service to give you .vtt files that you can add to a video element\u2019s track element\u2014or you can handcraft your own. (A quick aside: if your website has more videos than you can caption in a reasonable amount of time, prioritise the most popular videos, the most important videos, and the videos most relevant to people with disabilities. Then make sure your users know how to ask you to caption other videos as they encounter them.)\n1.2.3 If your website has recorded videos that have audio, you must add an \u201caudio description\u201d narration to the video to describe important visual details, or add text to the webpage to detail what happens in the video for users who cannot see the videos. (I like to add audio files from videos to my Huffduffer account so that I can listen to them while commuting.) Maybe your home page has a video where someone says, \u201cI\u2019d like to explain our new TPS reports\u201d while \u201cBill Lumbergh, division Vice President of Initech\u201d appears on the bottom of the screen. In that case, you should add an audio description to the video that announces \u201cBill Lumbergh, division Vice President of Initech\u201d, just before Bill starts speaking. As always, you can make life easier for yourself by considering all of your users, before the event: in this example, you could ask the speaker to begin by saying, \u201cI\u2019m Bill Lumbergh, division Vice President of Initech, and I\u2019d like to explain our new TPS reports\u201d\u2014so you won\u2019t need to spend time adding an audio description afterwards. \n1.2.4 If your website has live videos that have some audio, you should get a stenographer to provide real-time captions that you can include with the video. I\u2019ll be honest: this can prove tricky nowadays. The Web Content Accessibility Guidelines 2.0 predate YouTube Live, Instagram live Stories, Periscope, and other such services. If your organisation creates a lot of live videos, you might not have enough resources to provide real-time captions for each one. In that case, if you know the contents of the audio beforehand, publish the contents during the live video\u2014or failing that, publish a transcription as soon as possible.\n1.2.5 Remember what I said about the recorded videos that have audio? If you can choose to either add an audio description or add text to the webpage to detail what happens in the video, you should go with the audio description.\n1.2.6 If your website has recorded videos that include audio information, you could provide a sign language version of the audio information; some people understand sign language better than written language. (You don\u2019t need to caption a video of a sign language version of audio information.)\n1.2.7 If your website has recorded videos that have audio, and you need to add an audio description, but the audio doesn\u2019t have enough pauses for you to add an \u201caudio description\u201d narration, you could provide a separate version of that video where you have added pauses to fit the audio description into.\n1.2.8 Let\u2019s go back to the recorded videos that have audio once more! You could add text to the webpage to detail what happens in the video, so that people who can neither read captions nor hear dialogue and audio description can use braille displays to understand your video.\n1.2.9 If your website has live audio, you could get a stenographer to provide real-time captions. Again, if you know the contents of the audio beforehand, publish the contents during the live audio or publish a transcription as soon as possible.\n(Congratulations on making it this far! I know that seems like a lot to remember, but keep in mind that we\u2019ve covered a complex area: helping your users to understand multimedia information that they can\u2019t see and/or hear. Grab a mince pie to celebrate, and let\u2019s keep going.)\n1.3.1 You must mark up your website\u2019s content so that your user\u2019s browser, and any assistive technology they use, can understand the hierarchy of the information and how each piece of information relates to the rest. Once again, you probably know how to do this: use the most appropriate HTML element for each piece of information. Mark up headings, lists, buttons, radio buttons, checkboxes, and links with the most appropriate HTML element. If you\u2019re looking for something to do to keep you busy this Christmas, scroll through the list of the elements of HTML. Do you notice any elements that you didn\u2019t know, or that you\u2019ve never used? Do you notice any elements that you could use on your current projects, to mark up the content more accurately? Also, revise HTML table advanced features and accessibility, how to structure an HTML form, and how to use the native form widgets\u2014you might be surprised at how much you can do with just HTML! Once you\u2019ve mastered those, you can make your website much more usable for your all of your users.\n1.3.2 If your webpage includes information that your user has to read in a certain order, you must make sure that their browser and assistive technology can present the information in that order. Don\u2019t rely on CSS or whitespace to create that order visually. Check that the order of the information makes sense when CSS and whitespace aren\u2019t formatting it. Also, try using the Tab key to move the focus through the links and form widgets on your webpage. Does the focus go where you expect it to? Keep this in mind when using order in CSS Grid or Flexbox.\n1.3.3 You must not presume that your users can identify sensory characteristics of things on your webpage. Some users can\u2019t tell what you\u2019ve positioned where on the screen. For example, instead of asking your users to \u201cChoose one of the options on the left\u201d, you could ask them to \u201cChoose one of our new products\u201d and link to that section of the webpage.\n1.4.1 You must not rely on colour as the only way to convey something to your users. Some of your users can\u2019t see, and some of your users can\u2019t distinguish between colours. For example, if your webpage uses green to highlight the products that your shop has in stock, you could add some text to identify those products, or you could group them under a sub-heading.\n1.4.2  If your webpage automatically plays a sound for more than 3 seconds, you must make sure your users can stop the sound or change its volume. Don\u2019t rely on your user turning down the volume on their computer; some users need to hear the screen reader on their computer, and some users just want to keep listening to whatever they were listening before your webpage interrupted them!\n1.4.3 You should make sure that your text contrasts enough with its background, so that your users can read it. Bookmark Lea Verou\u2019s Contrast Ratio calculator now. You can enter the text colour and background colour as named colours, or as RGB, RGBa, HSL, or HSLa values. You should make sure that:\n\nnormal text that set at 24px or larger has a ratio of at least 3:1;\nbold text that set at 18.75px or larger has a ratio of at least 3:1;\nall other text has a ratio of at least 4\u00bd:1.\n\nYou don\u2019t have to do this for disabled form controls, decorative stuff, or logos\u2014but you could!\n1.4.4 You should make sure your users can resize the text on your website up to 200% without using their assistive technology\u2014and still access all your content and functionality. You don\u2019t have to do this for subtitles or images of text.\n1.4.5 You should avoid using images of text and just use text instead. In 1998, Jeffrey Veen\u2019s first Hot Design Tip said, \u201cText is text. Graphics are graphics. Don\u2019t confuse them.\u201d Now that you can apply powerful CSS text-styling properties, use CSS Grid to precisely position text, and choose from thousands of web fonts (Jeffrey co-founded Typekit to help with this), you pretty much never need to use images of text. The guidelines say you can use images of text if you let your users specify the font, size, colour, and background of the text in the image of text\u2014but I\u2019ve never seen that on a real website. Also, this doesn\u2019t apply to logos.\n1.4.6 Let\u2019s go back to colour contrast for a second. You could make your text contrast even more with its background, so that even more of your users can read it. To do that, use Lea Verou\u2019s Contrast Ratio calculator to make sure that:\n\nnormal text that is 24px or larger has a ratio of at least 4\u00bd:1;\nbold text that 18.75px or larger has a ratio of at least 4\u00bd:1;\nall other text has a ratio of at least 7:1.\n\n1.4.7 If your website has recorded speech, you could make sure there are no background sounds, or that your users can turn off any background sounds. If that\u2019s not possible, you could make sure that any background sounds that last longer than a couple of seconds are at least four times quieter than the speech. This doesn\u2019t apply to audio Captchas, audio logos, singing, or rapping. (Yes, these guidelines mention rapping!)\n1.4.8 You could make sure that your users can reformat blocks of text on your website so they can read them better. To do this, make sure that your users can:\n\nspecify the colours of the text and the background, and\nmake the blocks of text less than 80-characters wide, and \nalign text to the left (or right for right-to-left languages), and \nset the line height to 150%, and \nset the vertical distance between paragraphs to 1\u00bd times the line height of the text, and \nresize the text (without using their assistive technology) up to 200% and still not have to scroll horizontally to read it.\n\nBy the way, when you specify a colour for text, always specify a colour for its background too. Don\u2019t rely on default background colours!\n1.4.9 Let\u2019s return to images of text for a second. You could make sure that you use them only for decoration and logos.\nCan users operate the controls and links on your website?\nThe second guideline has criteria that help you prevent your users from asking, \u201cHow the **** does this thing work?\u201d\n2.1.1 You must make sure that you users can carry out all of your website\u2019s activities with just their keyboard, without time limits for pressing keys. (This doesn\u2019t apply to drawing or anything else that requires a pointing device such as a mouse.) Again, if you use the most appropriate HTML element for each piece of information and for each form element, this should prove easy.\n2.1.2 You must make sure that when the user uses the keyboard to focus on some part of your website, they can then move the focus to some other part of your webpage without needing to use a mouse or touch the screen. If your website needs them to do something complex before they can move the focus elsewhere, explain that to your user. These \u201ckeyboard traps\u201d have become rare, but beware of forms that move focus from one text box to another as soon as they receive the correct number of characters.\n2.1.3 Let\u2019s revisit making sure that you users can carry out all of your website\u2019s activities with just their keyboard, without time limits for pressing keys. You could make sure that your user can do absolutely everything on your website with just the keyboard.\n2.2.1 Sometimes people need more time than you might expect to complete a task on your website. If any part of your website imposes a time limit on a task, you must do at least one of these: \n\nlet your users turn off the time limit before they encounter it; or\nlet your users increase the time limit to at least 10 times the default time limit before they encounter it; or\nwarn your users before the time limit expires and give them at least 20 seconds to extend it, and let them extend it at least 10 times.\n\nRemember: these guidelines are practical. They allow you to enforce time limits for real-time events such as auctions and ticket sales, where increasing or extending time limits wouldn\u2019t make sense. Also, the guidelines allow you to enforce a maximum time limit of 20 hours. The editors chose 20 hours because people need to go to sleep at some stage. See? Practical!\n2.2.2 In my experience, this criterion remains the least well-known\u2014even though some users can only use websites that conform to it. If your website presents content alongside other content that can distract users by automatically moving, blinking, scrolling, or updating, you must make sure that your users can:\n\npause, stop, or hide the other content if it\u2019s not essential and lasts more than 5 seconds; and\npause, stop, hide, or control the frequency of the other content if it automatically updates.\n\nIt\u2019s OK if your users miss live information such as stock price updates or football scores; you can\u2019t do anything about that! Also, this doesn\u2019t apply to animations such as progress bars that you put on a website to let all users know that the webpage isn\u2019t frozen.\n(If this one sounds complex, just add a pause button to anything that might distract your users.)\n2.2.3 Let\u2019s go back to time limits on tasks on your website. You could   make your website even easier to use by removing all time limits except those on real-time events such as auctions and ticket sales. That would mean your user wouldn\u2019t need to interact with a timer at all.\n2.2.4 You could let your users turn off all interruptions\u2014server updates, promotions, and so on\u2014apart from any emergency information.\n2.2.5 This is possibly my favourite of these criteria! After your website logs your user out, you could make sure that when they log in again, they can continue from where they were without having lost any information. Do that, and you\u2019ll be on everyone\u2019s Nice List this Christmas.\n2.3.1 You must make sure that nothing flashes more than three times a second on your website, unless you can make sure that the flashes remain below the acceptable general flash and red flash thresholds\u2026\n2.3.2 \u2026or you could just make sure that nothing flashes more than three times per second on your website. This is usually an easier goal.\n2.4.1 You must make sure that your users can jump past any blocks of content, such as navigation menus, that are repeated throughout your website. You know the drill here: using HTML\u2019s sectioning elements such as header, nav, main, aside, and footer allows users with assistive technology to go straight to the content they need, and adding \u201cSkip Navigation\u201d links allows everyone to get to your main content faster.\n2.4.2 You must add a proper title to describe each webpage\u2019s topic. Your webpage won\u2019t even validate without a title element, so make it a useful one.\n2.4.3 If your users can focus on links and native form widgets, you must make sure that they can focus on elements in an order that makes sense.\n2.4.4 You must make sure that your users can understand the purpose of a link when they read:\n\nthe text of the link; or\nthe text of the paragraph, list item, table cell, or table header for the cell that contains the link; or\nthe heading above the link.\n\nYou don\u2019t have to do that for games and quizzes.\n2.4.5 You should give your users multiple ways to find any webpage within a set of webpages. Add site-wide search and a site map and you\u2019re done!\nThis doesn\u2019t apply for a webpage that is part of a series of actions (like a shopping cart and checkout flow) or to a webpage that is a result of a series of actions (like a webpage confirming that the user has bought what was in the shopping cart).\n2.4.6 You should help your users to understand your content by providing:\n\nheadings that describe the topics of you content;\nlabels that describe the purpose of the native form widgets on the webpage.\n\n2.4.7 You should make sure that users can see which element they have focussed on. Next time you use your website, try hitting the Tab key repeatedly. Does it visually highlight each item as it moves focus to it? If it doesn\u2019t, search your CSS to see whether you\u2019ve applied outline: 0; to all elements\u2014that\u2019s usually the culprit. Use the :focus pseudo-element to define how elements should appear when they have focus.\n2.4.8 You could help your user to understand where the current webpage is located within your website. Add \u201cbreadcrumb navigation\u201d and/or a site map and you\u2019re done.\n2.4.9 You could make links even easier to understand, by making sure that your users can understand the purpose of a link when they read the text of the link. Again, you don\u2019t have to do that for games and quizzes.\n2.4.10 You could use headings to organise your content by topic. \nCan users understand your content?\nThe third guideline has criteria that help you prevent your users from asking, \u201cWhat the **** does this mean?\u201d\n3.1.1 Let\u2019s start this section with the criterion that possibly takes the least time to implement; you must make sure that the user\u2019s browser can identify the main language that your webpage\u2019s content is written in. For a webpage that has mainly English content, use <html lang=\"en\">. \n3.1.2 You  must specify when content in another language appears in your webpage, like so: <q>I wish you a <span lang=\"fr\">Joyeux No\u00ebl</span>.</q>. You don\u2019t have to do this for proper names, technical terms, or words that you can\u2019t identify a language for. You also don\u2019t have to do it for words from a different language that people consider part of the language around those words; for example, <q>Come to our Christmas rendezvous!</q> is OK.\n3.1.3 You could make sure that your users can find out the meaning of any unusual words or phrases, including idioms like \u201cstocking filler\u201d or \u201cBah! Humbug!\u201d and jargon such as \u201cVoiceOver\u201d and \u201cTalkBack\u201d. Provide a glossary or link to a dictionary.\n3.1.4 You could make sure that your users can find out the meaning of any    abbreviation. For example, VoiceOver pronounces \u201cXmas\u201d as \u201cSmas\u201d instead of \u201cChristmas\u201d. Using the abbr element and linking to a glossary can help. (Interestingly, VoiceOver pronounces \u201cabbr\u201d as \u201cabbreviation\u201d!)\n3.1.5 Do your users need to be able to read better than a typically educated nine-year-old, to read your content (apart from proper names and titles)? If so, you could provide a version that doesn\u2019t require that level of reading ability, or you could provide images, videos, or audio to explain your content. (You don\u2019t have to add captions or audio description to those videos.)\n3.1.6 You could make sure that your users can access the pronunciation of any word in your content if that word\u2019s meaning depends on its pronunciation. For example, the word \u201cclose\u201d could have one of two meanings, depending on pronunciation, in a phrase such as, \u201cReady for Christmas? Close now!\u201d\n3.2.1 Some users need to focus on elements to access information about them. You must make sure that focusing on an element doesn\u2019t trigger any major changes, such as opening a new window, focusing on another element, or submitting a form.\n3.2.2 Webpages are easier for users when the controls do what they\u2019re supposed to do. Unless you have warned your users about it, you must make sure that changing the value of a control such as a text box, checkbox, or drop-down list doesn\u2019t trigger any major changes, such as opening a new window, focusing on another element, or submitting a form.\n3.2.3 To help your users to find the content they want on each webpage, you should put your navigation elements in the same place on each webpage. (This doesn\u2019t apply when your user has changed their preferences or when they use assistive technology to change how your content appears.) \n3.2.4 When a set of webpages includes things that have the same functionality on different webpages, you should name those things consistently. For example, don\u2019t use the word \u201cSearch\u201d for the search box on one webpage and \u201cFind\u201d for the search box on another webpage within that set of webpages.\n3.2.5 Let\u2019s go back to major changes, such as a new window opening, another element taking focus, or a form being submitted. You could make sure that they only happen when users deliberately make them happen, or when you have warned users about them first. For example, you could give the user a button for updating some content instead of automatically updating that content. Also, if a link will open in a new window, you could add the words \u201copens in new window\u201d to the link text.\n3.3.1 Users make mistakes when filling in forms. Your website must identify each mistake to your user, and must describe the mistake to your users in text so that the user can fix it. One way to identify mistakes reliably to your users is to set the aria-invalid attribute to true in the element that has a mistake. That makes sure that users with assistive technology will be alerted about the mistake. Of course, you can then use the [aria-invalid=\"true\"] attribute selector in your CSS to visually highlight any such mistakes. Also, look into how certain attributes of the input element such as required, type, and list can help prevent and highlight mistakes.\n3.3.2 You must include labels or instructions (and possibly examples) in your website\u2019s forms, to help your users to avoid making mistakes. \n3.3.3 When your user makes a mistake when filling in a form, your webpage should suggest ways to fix that mistake, if possible. This doesn\u2019t apply in scenarios where those suggestions could affect the security of the content.\n3.3.4 Whenever your user submits information that:\n\nhas legal or financial consequences; or\naffects information that they have previously saved in your website; or\nis part of a test\n\n\u2026you should make sure that they can:\n\nundo it; or\ncorrect any mistakes, after your webpage checks their information; or\nreview, confirm, and correct the information before they finally submit it.\n\n3.3.5 You could help prevent your users from making mistakes by providing obvious, specific help, such as examples, animations, spell-checking, or extra instructions.\n3.3.6 Whenever your user submits any information, you could make sure that they can:\n\nundo it; or\ncorrect any mistakes, after your webpage checks their information; or\nreview, confirm, and correct the information before they finally submit it.\n\nHave you made your website robust enough to work on your users\u2019 browsers and assistive technologies?\nThe fourth and final guideline has criteria that help you prevent your users from asking, \u201cWhy the **** doesn\u2019t this work on my device?\u201d\n4.1.1 You must make sure that your website works as well as possible with current and future browsers and assistive technology. Prioritise  complying with web standards instead of relying on the capabilities of currently popular devices and browsers. Web developers didn\u2019t expect their users to be unwrapping the Wii U Browser five years ago\u2014who knows what browsers and assistive technologies our users will be unwrapping in five years\u2019 time? Avoid hacks, and use the W3C Markup Validation Service to make sure that your HTML has no errors.\n4.1.2 If you develop your own user interface components, you must make their name, role, state, properties, and values available to your user\u2019s browsers and assistive technologies. That should make them almost as accessible as standard HTML elements such as links, buttons, and checkboxes.\n\u201c\u2026and a partridge in a pear tree!\u201d\n\u2026as that very long Christmas song goes. We\u2019ve covered a lot in this article\u2014because your users have a lot of different levels of ability. Hopefully this has demystified the Web Content Accessibility Guidelines 2.0 for you. Hopefully you spotted a few situations that could arise for users on your website, and you now know how to tackle them. \nTo start applying what we\u2019ve covered, you might like to look at Sarah Horton and Whitney Quesenbery\u2019s personas for Accessible UX. Discuss the personas, get into their heads, and think about which aspects of your website might cause problems for them. See if you can apply what we\u2019ve covered today, to help users like them to do what they need to do on your website.\nHow to know when your website is perfectly accessible for everyone\nLOL! There will never be a time when your website becomes perfectly accessible for everyone. Don\u2019t aim for that. Instead, aim for regularly testing and making your website more accessible.\nWeb Content Accessibility Guidelines (WCAG) 2.1\nThe W3C hope to release the Web Content Accessibility Guidelines (WCAG) 2.1 as a \u201crecommendation\u201d (that\u2019s what the W3C call something that we should start using) by the middle of next year. Ten years may seem like a long time to move from version 2.0 to version 2.1, but consider the scale of the task: the editors have to update the guidelines to cover all the new ways that people interact with new technologies, while keeping the guidelines backwards-compatible. Keep an eye out for 2.1!\nYou\u2019ll go down in history\nOne last point: I\u2019ve met a surprising number of web designers and developers who do great work to make their websites more accessible without ever telling their users about it. Some of your potential customers have possibly tried and failed to use your website in the past. They probably won\u2019t try again unless you let them know that things have improved. A quick Twitter search for your website\u2019s name alongside phrases like \u201cassistive technology\u201d, \u201cdoesn\u2019t work\u201d, or \u201c#fail\u201d can let you find frustrated users\u2014so you can tell them about how you\u2019re making your website more accessible. Start making your websites work better for everyone\u2014and please, let everyone know.", "year": "2017", "author": "Alan Dalton", "author_slug": "alandalton", "published": "2017-12-03T00:00:00+00:00", "url": "https://24ways.org/2017/wcag-for-people-who-havent-read-them/", "topic": "code"}
{"rowid": 85, "title": "Starting Your Project on the Right Foot (and Keeping It There)", "contents": "I\u2019m not sure if anything is as terrifying as beginning a new design project. I often spend hours trying to find the best initial footing in a design, so I\u2019ve been working hard to improve my process, particularly for the earliest stages of a project. I want\u00a0to smooth out the bumps that disrupt my creative momentum and focus on the emotional highs and lows I experience, and then try to minimize the lows and ride the highs as long as possible. \n\nDesign is often a struggle broken up by blissful moments of creative clarity that provide valuable force to move your work forward. Momentum is a powerful tool in creative work, and it\u2019s something we don\u2019t always maximize when we\u2019re working because of the hectic nature of our field.\u00a0Obviously, every designer is going to have a different process, but I thought I\u2019d share some of the methods I\u2019ve begun to adopt. I hope this will spark a conversation among designers who are interested in looking at process in a new way.\n\nJump-starting a project\n\nI cannot overstate the importance of immersing yourself in design and collecting ample amounts of inspiration when beginning a project. I make it a daily practice to visit a handful of sites (Dribbble, Graphic Exchange, Web Creme, siteInspire, Designspiration, and others) and save any examples of design that I like. I then sort them into general categories (publication design, illustration, typography, web design, and so on). Enjoying a bit of fresh design every day helps me absorb it and analyze why it\u2019s effective instead of just imitating it.\u00a0\n\nMany designers are afraid to look at too much design for fear that they\u2019ll be tempted to copy it, but I feel a steady influx of design inspiration reduces that possibility. You\u2019re much more likely to take the easy way out and rip off a design if you\u2019re scrambling for inspiration after getting stuck. If you are immersed in design from a variety of mediums, you\u2019ll engage your creative brain on multiple levels and have an easier time creating something unique for your project. Looking at good design will not make you a good designer but it will make you a better designer.\n\nDesign is design\n\nTry not to limit your visual research to the medium you\u2019re working in. Websites, books, posters and packaging all have their own unique limitations and challenges, and any one of those characteristics could be useful to you. Posters need to grab the viewer and pass on a small tidbit of information; packaging needs to encourage physical interaction; and websites need to encourage exploration. If you know the challenges you\u2019ll be facing, you will know where to look for design that tackles those same problems.\n\nI find it refreshing to look at design from the turn of the nineteenth century, when type was laid out on objects without thought to aesthetics. Many vintage packages break all sorts of modern design rules, and looking at that kind of work is a great way to spark your creativity. Pulling yourself out of the box and away from the rules of what you\u2019re working on can reveal solutions that are innovative and unique.\u00a0After a little finessing, the warning label text from a 1940s hazardous chemical box from could have the exact type and icon arrangement you need for your project.\u00a0There\u2019s a massive pool of design to pull from that doesn\u2019t have the limitations the web has, and exploring those design worlds will help you grow your own repertoire.\n\nIf all else fails, start with the footer\n\nThe very beginning of a project is the most frustrating point in a project for me. I\u2019m trying to figure out typeface combinations, colors and the overall voice of the design, and until I find the right solutions, I\u2019m a wreck. I\u2019ve found often that my frustration stems from trying to solve too many problems at once. The beginning of a project has a lot of moving targets, nearly endless possible solutions, and constantly changing variables. You\u2019ll knock out one problem only to discover your solution doesn\u2019t jive with something you worked out earlier \u2014 you end up designing in circles.\n\nIf you find yourself getting stuck at the beginning of a website design, try working out one specific element of the site and see what emerges. I\u2019m going to recommend the footer. Why? Footers can easily be ignored in a design or become a dumping ground for items that couldn\u2019t be worked into the main layout. But, at the start of most projects, the minimum content requirements for the footer are usually established. There needs to be a certain number of links, social media buttons, copyright details, a search bar, and so on. It\u2019s a self-contained item within the design that has a specific purpose, and that\u2019s a great element to focus on when you\u2019re stuck in a design. Colors, typefaces, link styles, input fields and buttons can all be sketched out from just the footer. It\u2019s a very flexible element that can be as prominent or subtle as you want, and it\u2019s a solid starting point for setting the tone and style of a site.\n\nSave the details\n\nDesigners love details. I love details. But don\u2019t let nitpicking early on in your process kill your creative momentum.\u00a0Design is an emotional process, and being frustrated or defeated by a tricky problem or a graphical detail you just can\u2019t nail down can deflate your creative energies. If you hit a roadblock, set it aside and tackle another piece of the project. As you spend time engaged in a design, the style you develop will evolve according to the needs of the content, and you might arrive naturally at a solution that will work perfectly for the problem that had you stuck before.\u00a0\n\nIf I find myself working on one particular element for more than a half an hour without any clear movement, I shelve it. Designers often wear their obsessive detail-oriented tendencies as a badge of honor, but there\u2019s a difference between making the design better and wasting time. If you\u2019ve spent hours nudging elements around pixel by pixel and can\u2019t settle on something, it probably means what you\u2019re doing isn\u2019t making a huge improvement on the design. Don\u2019t be afraid to let it lie and come at it again with fresh eyes. You will be better equipped to tackle the finer points of a project once you\u2019ve got the broad strokes defined.\n\nHave a plan when you start and stop designing\n\nWe all know that creativity isn\u2019t something you can turn on effortlessly, and it\u2019s easy to forget the emotional process that goes along with design.\u00a0If you leave a project in a place of frustration, it\u2019s going to stay with you in your free time and affect you negatively, like a dark cloud of impending disaster. Try to end each design session with a victory, a small bit of definable progress that you can take with you in your downtime. Even something as small as finding the right opacity for the interior shadow on the search bar in the header of the site is a win.\u00a0Likewise, when you return to a project after a break, it can be difficult to get the ball rolling on the design again if you set it down without a clear path for the next steps. I find that I work on details best when I\u2019m returning from downtime, when I\u2019m fresh and re-energized and ready to dig in again. Try to pick out at least one element you\u2019d like to fine-tune when you are winding down in a design session and use it to kick-start your next session.\n\nContent is king\n\nI would argue there is nothing more crucial to the success of a design than having the content defined from the outset.\u00a0Designing without content is similar to designing without an audience, and designing with vague ideas of content types and character limits is going to result in a muted design that doesn\u2019t reach its full potential. Images and language go hand in hand with design, and can take a design from functional to outstanding if you have them available from the outset. We don\u2019t always have the luxury of having content to build a design around, but fight for it whenever you can. For example, if the site you are designing is full of technical jargon, your paragraphs might need a longer line length to accommodate the longer words being used.\u00a0\n\nOften, working with content will lead to design solutions you wouldn\u2019t have come to otherwise.\u00a0Design speaks to content, and content speaks to design. Lorem ipsum doesn\u2019t speak to anyone (unless you know Latin, in which case, congratulations!).\n\nEvery project has its own set of needs, and every designer has his or her own method of working. There\u2019s obviously no perfect process to design, and being dogmatic about process can be just as harmful as not having one. Exposing yourself to new design and new ways of designing is an easy way to test your skills and grow. When things are hard and you can\u2019t get any momentum going on a design, this is when your skill set is truly challenged. We all hope to get wonderful projects with great assets and ample creative possibilities, but you won\u2019t always be so blessed, and this is when the quality of your process is really going to shine.", "year": "2012", "author": "Bethany Heck", "author_slug": "bethanyheck", "published": "2012-12-02T00:00:00+00:00", "url": "https://24ways.org/2012/starting-your-project-on-the-right-foot/", "topic": "process"}
{"rowid": 232, "title": "Optimize Your Web Design Workflow", "contents": "I\u2019m not sure about you, but I still favour using Photoshop to create my designs for the web. I agree that this application, even with its never-ending feature set, is not the perfect environment to design websites in. The ideal application doesn\u2019t exist yet, however, so until it does it\u2019s maybe not such a bad idea to investigate ways to optimize our workflow.\n\nWhy use Photoshop?\n\nIt will probably not come as a surprise if I say that Photoshop and Illustrator are the applications that I know best and feel most comfortable and creative in. Some people prefer Fireworks for web design. Even though I understand people\u2019s motivations, I still prefer Photoshop personally. On the occasions that I gave Fireworks a try, I ended up just using the application to export my images as slices, or to prepare a dummy for the client. For some reason, I\u2019ve never been able to find my way in that app. There were always certain things missing that could only be done in either Photoshop or Illustrator, which bothered me.\n\nWhy not start in the browser?\n\nThese days, with CSS3 styling emerging, there are people who find it more efficient to design in the browser. I agree that at a certain point, once the basic design is all set and defined, you can jump right into the code and go from there. But the actual creative part, at least for me, needs to be done in an application such as Photoshop.\n\nAs a designer I need to be able to create and experiment with shapes on the fly, draw things, move them around, change colours, gradients, effects, and so on. I can\u2019t see me doing this with code. I\u2019m sure if I switch to markup too quickly, I might end up with a rather boxy and less interesting design. Once I start playing with markup, I leave my typical \u2018design zone\u2019. My brain starts thinking differently \u2013 more rational and practical, if you know what I mean; I start to structure and analyse how to mark up my design in the most efficient semantic way. When I design, I tend to let that go for a bit. I think more freely and not so much about the limitations, as it might hinder my creativity. Now that you know my motivations to stick with Photoshop for the time being, let\u2019s see how we can optimize this beast.\n\nOptimize your Photoshop workspace\n\nIn Photoshop CS5 you have a few default workspace options to choose from which can be found at the top right in the Application Bar (Window\u2009>\u2009Application Bar).\n\n\n\nYou can set up your panels and palettes the way you want, starting from the \u2018Design\u2019 workspace option, and save this workspace for future web work. Here is how I have set up things for when I work on a website design:\n\n\n\nI have the layers palette open, and I keep the other palettes collapsed. Sometimes, when space permits, I open them all. For designers who work both on print and web, I think it\u2019s worthwhile to save a workspace for both, or for when you\u2019re doing photo retouching.\n\nSet up a grid\n\nWhen you work a lot with Shape Layers like I do, it\u2019s really helpful to enable the Grid (View\u2009>\u2009Show\u2009>\u2009Grid) in combination with Snap to Grid (View\u2009>\u2009Snap To\u2009>\u2009Grid). This way, your vector-based work will be pixel-sharp, as it will always snap to the grid, and so you don\u2019t end up with blurry borders.\n\n\n\nTo set up your preferred grid, go to Preferences\u2009>\u2009Guides, Grids and Slices. A good setting is to use \u2018Gridline Every 10 pixels\u2019 and \u2018Subdivision 10\u2019. You can switch it on and off at any time using the shortcut Cmd/Ctrl + \u2019.\n\n\n\nIt might also help to turn on Smart Guides (View\u2009>\u2009Show\u2009>\u2009Smart Guides).\n\nAnother important tip for making sure your Shape Layer boxes and other shapes are perfectly aligned to the pixel grid when you draw them is to enable Snap to Pixels. This option can be enabled in the Application bar in the Geometry options dropdown menu when you select one of the shape tools from the toolbox.\n\n\n\nUse Shape Layers\n\nTo keep your design as flexible as possible, it\u2019s a good thing to use Shape Layers wherever you can as they are scalable. I use them when I design for the iPhone. All my icons, buttons, backgrounds, illustrative graphics \u2013 they are all either Smart Objects placed from Illustrator, or Shape Layers. This way, the design is scalable for the retina display.\n\n\n\nUse Smart Objects\n\nAmong the things I like a lot in Photoshop are Smart Objects. Smart Objects preserve an image\u2019s source content with all its original characteristics, enabling you to perform non-destructive editing to the layer. For me, this is the ideal way of making my design flexible.\n\n\n\nFor example, a lot of elements are created in Illustrator and are purely vector-based. Placing these elements in Photoshop as Smart Objects (via copy and paste, or dragging from Illustrator into Photoshop) will keep them vector-based and scalable at all times without loss of quality.\n\n\n\nAnother way you could use Smart Objects is whenever you have repeating elements; for example, if you have a stream or list of repeating items. You could, for instance, create one, two or three different items (for the sake of randomness), make each one a Smart Object, and repeat them to create the list. Then, when you have to update, you need only change the Smart Object, and the update will be automatically applied in all its linked instances.\n\nTurning photos into Smart Objects before you resize them is also worth considering \u2013 you never know when you\u2019ll need that same photo just a bit bigger. It keeps things more flexible, as you leave room to resize the image at a later stage. I use this in combination with the Smart Filters a lot, as it gives me such great flexibility.\n\n\n\nI usually use Smart Objects as well for the main sections of a web page, which are repeated across different pages of a site. So, for elements such as the header, footer and sidebar, it can be handy for bigger projects that are constantly evolving, where you have to create a lot of different pages in Photoshop.\n\nYou could save a template page that has the main sections set up as Smart Objects, always in their latest version. Each time you need to create new page, you can start from that template file. If you need to update an existing page because the footer (or sidebar, or header) has been updated, you can drag the updated Smart Object into this page. Although, do I wish Photoshop made it possible to have Smart Objects live as separate files, which are then linked to my different pages. Then, whenever I update the Smart Object, the pages are automatically updated next time I open the file. This is how linked files work in InDesign and Illustrator when you place a external image.\n\nUse Layer Comps\n\nIn some situations, using Layer Comps can come in handy. I try to use them when the design consists of different states; for example, if there are hidden and show states of certain content, such as when content is shown after clicking a certain button. It can be useful to create a Layer Comp for each state. So, when you switch between the two Layer Comps, you\u2019re switching between the two states.\n\n\n\nIt\u2019s OK to move or hide content in each of these states, as well as apply different layer styles. I find this particularly useful when I need to save separate JPEG versions of each state to show to the client, instead of going over all the eye icons in the layers palette to turn the layers\u2019 visibility on or off.\n\n\n\nCreate a set of custom colour swatches\n\nI tend to use a distinct colour Swatches palette for each project I work on, by saving a separate Swatches palette in project\u2019s folder (as an .ase file). You can do this through the palette\u2019s dropdown menu, choosing Save Swatches for Exchange.\n\n\n\nSelecting this option gives you the flexibility to load this palette in other Adobe applications like Illustrator, InDesign or Fireworks. This way, you have the colours of any particular project at hand. I name each colour, using the hexadecimal values.\n\n\n\nLoading, saving or changing the view of the Swatches palette can be done via the palette\u2019s dropdown menu. My preferred view is \u2018Small List\u2019 so I can see the hexadecimal values or other info I have added in the description.\n\nI do wish Photoshop had the option of loading several different Styles palettes, so I could have two or more of them open at the same time, but each as a separate palette. This would be handy whenever I switch to another project, as I\u2019m usually working on more than one project in a day. At the moment, you can only add a set of colours to the palette that is already open, which is frustrating and inefficient if you need to update the palette of a project separately.\n\nCreate a set of custom Styles\n\nJust like saving a Swatches palette, I also always save the styles I apply in the Styles palette as a separate Styles file in the project\u2019s folder when I work on a website design or design for iPhone/iPad. During the design process, I can save it each time styles are added. Again, though, it would be great if we could have different Styles palettes open at the same time.\n\n\n\nUse a scratch file\n\nWhat I also find particularly timesaving, when working on a large project, is using some kind of scratch file. By that, I mean a file that has elements in place that you reuse a lot in the general design. Think of buttons, icons and so on, that you need in every page or screen design. This is great for both web design work and iPad/iPhone work. \n\n\n\nUse the slice tool\n\nThis might not be something you think of at first, because you probably associate this way of working with \u2018old-school\u2019 table-based techniques. Still, you can apply your slice any way you want, keeping your way of working in mind. Just think about it for a second. If you use the slice tool, and you give each slice its proper filename, you don\u2019t have to worry about it when you need to do updates on the slice or image. Photoshop will remember what the image of that slice is called and which \u2018Save for Web\u2019 export settings you\u2019ve used for it. You can also export multiple slices all at once, or export only the ones you need using \u2018Save selected slices\u2019.\n\n\n\nI hope this list of optimization tips was useful, and that they will help you improve and enjoy your time in Photoshop. That is, until the ultimate web design application makes its appearance.

{"rowid": 267, "title": "Taming Complexity", "contents": "I\u2019m going to step into my UX trousers for this one. I wouldn\u2019t usually wear them in public, but it\u2019s Christmas, so there\u2019s nothing wrong with looking silly.\n\nAnyway, to business. Wherever I roam, I hear the familiar call for simplicity and the denouncement of complexity. I read often that the simpler something is, the more usable it will be. We understand that simple is hard to achieve, but we push for it nonetheless, convinced it will make what we build easier to use. Simple is better, right?\n\nWell, I\u2019ll try to explore that. Much of what follows will not be revelatory to some but, like all good lessons, I think this serves as a welcome reminder that as we live in a complex world it\u2019s OK to sometimes reflect that complexity in the products we build.\n\nMyths and legends\n\nLess is more, we\u2019ve been told, ever since master of poetic verse Robert Browning used the phrase in 1855. Well, I\u2019ve conducted some research, and it appears he knew nothing of web design. Neither did modernist architect Ludwig Mies van der Rohe, a later pedlar of this worthy yet contradictory notion. Broad is narrow. Tall is short. Eggs are chips. See: anyone can come up with this stuff.\n\nTo paraphrase Einstein, simple doesn\u2019t have to be simpler. In other words, simple doesn\u2019t dictate that we remove the complexity. Complex doesn\u2019t have to be confusing; it can be beautiful and elegant. On the web, complex can be necessary and powerful. A website that simplifies the lives of its users by offering them everything they need in one site or screen is powerful. For some, the greater the density of information, the more useful the site.\n\nIn our decision-making process, principles such as Occam\u2019s razor\u2019s_razor (in a nutshell: simple is better than complex) are useful, but simple is for the user to determine through their initial impression and subsequent engagement. What appears simple to me or you might appear very complex to someone else, based on their own mental model or needs. We can aim to deliver simple, but they\u2019ll be the judge.\n\nAs a designer, developer, content alchemist, user experience discombobulator, or whatever you call yourself, you\u2019re often wrestling with a wealth of material, a huge number of features, and numerous objectives. In many cases, much of that stuff is extraneous, and goes in the dustbin. However, it can be just as likely that there\u2019s a truckload of suggested features and content because it all needs to be there. Don\u2019t be afraid of that weight.\n\nIn the right hands, less can indeed mean more, but it\u2019s just as likely that less can very often lead to, well\u2026 less.\n\nComplexity is powerful\n\nSimple is the ability to offer a powerful experience without overwhelming the audience or inducing information anxiety. Giving them everything they need, without having them ferret off all over a site to get things done, is important.\n\nIt\u2019s useful to ask throughout a site\u2019s lifespan, \u201cdoes the user have everything they need?\u201d It\u2019s so easy to let our designer egos get in the way and chop stuff out, reduce down to only the things we want to see. That benefits us in the short term, but compromises the audience long-term.\n\nThe trick is not to be afraid of complexity in itself, but to avoid creating the perception of complexity. Give a user a flight simulator and they\u2019ll crash the plane or jump out. Give them everything they need and more, but make it feel simple, and you\u2019re building a relationship, empowering people.\n\nThis can be achieved carefully with what some call gradual engagement, and often the sensible thing might be to unleash complexity in carefully orchestrated phases, initially setting manageable levels of engagement and interaction, gradually increasing the inherent power of the product and fostering an empowered community.\n\nThe design aesthetic\n\nHere\u2019s a familiar scenario: the client or project lead gets overexcited and skips most of the important decision-making, instead barrelling straight into a bout of creative direction Tourette\u2019s. Visually, the design needs to be minimal, white, crisp, full of white space, have big buttons, and quite likely be \u201cclean\u201d. Of course, we all like our websites to be clean as that\u2019s more hygienic.\n\nBut what do these words even mean, really? Early in a project they\u2019re abstract distractions, unnecessary constraints. This premature narrowing forces us to think much more about throwing stuff out rather than acknowledging that what we\u2019re building is complex, and many of the components perhaps necessary.\n\nSimple is not a formula. It cannot be achieved just by using a white background, by throwing things away, or by breathing a bellowsful of air in between every element and having it all float around in space. Simple is not a design treatment. Simple is hard. Simple requires deep investigation, a thorough understanding of every aspect of a project, in line with the needs and expectations of the audience.\n\nRecognizing this helps us empathize a little more with those most vocal of UX practitioners. They usually appreciate that our successes depend on a thorough understanding of the user\u2019s mental models and expected outcomes. I personally still consider UX people to be web designers like the rest of us (mainly to wind them up), but they\u2019re web designers that design every decision, and by putting the user experience at the heart of their process, they have a greater chance of finding simplicity in complexity. The visual design aesthetic \u2014 the fa\u00e7ade \u2014 is only a part of that.\n\nDivide and conquer\n\nI\u2019m currently working on an app that\u2019s complex in architecture, and complex in ambition. We\u2019ll be releasing in carefully orchestrated private phases, gradually introducing more complexity in line with the unavoidably complex nature of the objective, but my job is to design the whole, the complete system as it will be when it\u2019s out of beta and beyond.\n\nI\u2019ve noticed that I\u2019m not throwing much out; most of it needs to be there. Therefore, my responsibility is to consider interesting and appropriate methods of navigation and bring everything together logically.\n\nI\u2019m using things like smart defaults, graphical timelines and colour keys to make sense of the complexity, techniques that are sympathetic to the content. They act as familiar points of navigation and reference, yet are malleable enough to change subtly to remain relevant to the information they connect. It\u2019s really OK to have a lot of stuff, so long as we make each component work smartly.\n\nIt\u2019s a divide and conquer approach. By finding simplicity and logic in each content bucket, I\u2019ve made more sense of the whole, allowing me to create key layouts where most of the simplified buckets are collated and sometimes combined, providing everything the user needs and expects in the appropriate places.\n\nI\u2019m also making sure I don\u2019t reduce the app\u2019s power. I need to reflect the scale of opportunity, and provide access to or knowledge of the more advanced tools and features for everyone: a window into what they can do and how they can help. I know it\u2019s the minority who will be actively building the content, but the power is in providing those opportunities for all.\n\nMuch of this will be familiar to the responsible practitioners who build websites for government, local authorities, utility companies, newspapers, magazines, banking, and we-sell-everything-ever-made online shops. Across the web, there are sites and tools that thrive on complexity.\n\nAlas, the majority of such sites have done little to make navigation intuitive, or empower audiences. Where we can make a difference is by striving to make our UIs feel simple, look wonderful, not intimidating \u2014 even if they\u2019re mind-meltingly complex behind that fa\u00e7ade.\n\nEmbrace, empathize and tame\n\nSo, there are loads of ways to exploit complexity, and make it seem simple. I\u2019ve hinted at some methods above, and we\u2019ve already looked at gradual engagement as a way to make sense of complexity, so that\u2019s a big thumbs-up for a release cycle that increases audience power.\n\nPrior to each and every release, it\u2019s also useful to rest on the finished thing for a while and use it yourself, even if you\u2019re itching to release. \u2018Ready\u2019 often isn\u2019t, and \u2018finished\u2019 never is, and the more time you spend browsing around the sites you build, the more you learn what to question, where to add, or subtract. It\u2019s definitely worth building in some contingency time for sitting on your work, so to speak.\n\nOne thing I always do is squint at my layouts. By squinting, I get a sort of abstract idea of the overall composition, and general feel for the thing. It makes my face look stupid, but helps me see how various buckets fit together, and how simple or complex the site feels overall.\n\nI mentioned the need to put our design egos to one side and not throw out anything useful, and I think that\u2019s vital. I\u2019m a big believer in economy, reduction, and removing the extraneous, but I\u2019m usually referring to decoration, bells and whistles, and fluff. I wouldn\u2019t ever advocate the complete removal of powerful content from a project roadmap.\n\nAbove all, don\u2019t fear complexity. Embrace and tame it. Work hard to empathize with audience needs, and you can create elegant, playful, risky, surprising, emotive, delightful, and ultimately simple things.", "year": "2011", "author": "Simon Collison", "author_slug": "simoncollison", "published": "2011-12-21T00:00:00+00:00", "url": "https://24ways.org/2011/taming-complexity/", "topic": "ux"}
{"rowid": 180, "title": "Going Nuts with CSS Transitions", "contents": "I\u2019m going to show you how CSS 3 transforms and WebKit transitions can add zing to the way you present images on your site.\n\nLaying the foundations\n\nFirst we are going to make our images look like mini polaroids with captions. Here\u2019s the markup:\n\n<div class=\"polaroid pull-right\">\n\t<img src=\"../img/seal.jpg\" alt=\"\">\n\t<p class=\"caption\">Found this little cutie on a walk in New Zealand!</p>\n</div>\n\nYou\u2019ll notice we\u2019re using a somewhat presentational class of pull-right here. This means the logic is kept separate from the code that applies the polaroid effect. The polaroid class has no positioning, which allows it to be used generically anywhere that the effect is required. The pull classes set a float and add appropriate margins\u2014they can be used for things like blockquotes as well.\n\n.polaroid {\n\twidth: 150px;\n\tpadding: 10px 10px 20px 10px;\n\tborder: 1px solid #BFBFBF;\n\tbackground-color: white;\n\t-webkit-box-shadow: 2px 2px 3px rgba(135, 139, 144, 0.4);\n\t-moz-box-shadow: 2px 2px 3px rgba(135, 139, 144, 0.4);\n\tbox-shadow: 2px 2px 3px rgba(135, 139, 144, 0.4);\n}\n\nThe actual polaroid effect itself is simply applied using padding, a border and a background colour. We also apply a nice subtle box shadow, using a property that is supported by modern WebKit browsers and Firefox 3.5+. We include the box-shadow property last to ensure that future browsers that support the eventual CSS3 specified version natively will use that implementation over the legacy browser specific version.\n\nThe box-shadow property takes four values: three lengths and a colour. The first is the horizontal offset of the shadow\u2014positive values place the shadow on the right, while negative values place it to the left. The second is the vertical offset, positive meaning below. If both of these are set to 0, the shadow is positioned equally on all four sides. The last length value sets the blur radius\u2014the larger the number, the blurrier the shadow (therefore the darker you need to make the colour to have an effect).\n\nThe colour value can be given in any format recognised by CSS. Here, we\u2019re using rgba as explained by Drew behind the first door of this year\u2019s calendar.\n\nRotation\n\nFor browsers that understand it (currently our old favourites WebKit and FF3.5+) we can add some visual flair by rotating the image, using the transform CSS 3 property.\n\n-webkit-transform: rotate(9deg);\n-moz-transform: rotate(9deg);\ntransform: rotate(9deg);\n\nRotations can be specified in degrees, radians (rads) or grads. WebKit also supports turns unfortunately Firefox doesn\u2019t just yet.\n\nFor our example, we want any polaroid images on the left hand side to be rotated in the opposite direction, using a negative degree value:\n\n.pull-left.polaroid {\n\t-webkit-transform: rotate(-9deg);\n\t-moz-transform: rotate(-9deg);\n\ttransform: rotate(-9deg);\n}\n\nMultiple class selectors don\u2019t work in IE6 but as luck would have it, the transform property doesn\u2019t work in any current IE version either. The above code is a good example of progressive enrichment: browsers that don\u2019t support box-shadow or transform will still see the image and basic polaroid effect.\n\n\n\nAnimation\n\nWebKit is unique amongst browser rendering engines in that it allows animation to be specified in pure CSS. Although this may never actually make it in to the CSS 3 specification, it degrades nicely and more importantly is an awful lot of fun!\n\nLet\u2019s go nuts.\n\nIn the next demo, the image is contained within a link and mousing over that link causes the polaroid to animate from being angled to being straight.\n\nHere\u2019s our new markup:\n\n<a href=\"http://www.flickr.com/photos/nataliedowne/2340993237/\" class=\"polaroid\">\n\t<img src=\"../img/raft.jpg\" alt=\"\">\n\tWhite water rafting in Queenstown\n</a>\n\nAnd here are the relevant lines of CSS:\n\na.polaroid {\n\t/* ... */\n   -webkit-transform: rotate(10deg);\n   -webkit-transition: -webkit-transform 0.5s ease-in;\n}\na.polaroid:hover,\na.polaroid:focus,\na.polaroid:active {\n\t/* ... */\n\t-webkit-transform: rotate(0deg);\n}\n\nThe @-webkit-transition@ property is the magic wand that sets up the animation. It takes three values: the property to be animated, the duration of the animation and a \u2018timing function\u2019 (which affects the animation\u2019s acceleration, for a smoother effect).\n\n-webkit-transition only takes affect when the specified property changes. In pure CSS, this is done using dynamic pseudo-classes. You can also change the properties using JavaScript, but that\u2019s a story for another time.\n\nThrowing polaroids at a table\n\nImagine there are lots of differently sized polaroid photos scattered on a table. That\u2019s the effect we are aiming for with our next demo.\n\n\n\nAs an aside: we are using absolute positioning to arrange the images inside a flexible width container (with a minimum and maximum width specified in pixels). As some are positioned from the left and some from the right when you resize the browser they shuffle underneath each other. This is an effect used on the UX London site.\n\nThis demo uses a darker colour shadow with more transparency than before. The grey shadow in the previous example worked fine, but it was against a solid background. Since the images are now overlapping each other, the more opaque shadow looked fake.\n\n-webkit-box-shadow: 2px 2px 4px rgba(0,0, 0, 0.3);\n-moz-box-shadow: 2px 2px 4px rgba(0,0, 0, 0.3);\nbox-shadow: 2px 2px 4px rgba(0,0, 0, 0.3);\n\nOn hover, as well as our previous trick of animating the image rotation back to straight, we are also making the shadow darker and setting the z-index to be higher than the other images so that it appears on top.\n\nAnd Finally\u2026\n\nFinally, for a bit more fun, we\u2019re going to simulate the images coming towards you and lifting off the page. We\u2019ll achieve this by making them grow larger and by offsetting the shadow & making it longer.\n\n\n\n\nScreenshot 1 shows the default state, while 2 shows our previous hover effect. Screenshot 3 is the effect we are aiming for, illustrated by demo 4.\n\na.polaroid {\n\t/* ... */\n\tz-index: 2;\n\t-webkit-box-shadow: 2px 2px 4px rgba(0,0, 0, 0.3);\n\t-moz-box-shadow: 2px 2px 4px rgba(0,0, 0, 0.3);\n\tbox-shadow: 2px 2px 4px rgba(0,0, 0, 0.3);\n\t-webkit-transform: rotate(10deg);\n\t-moz-transform: rotate(10deg);\n\ttransform: rotate(10deg);\n\t-webkit-transition: all 0.5s ease-in;\n}\na.polaroid:hover,\na.polaroid:focus,\na.polaroid:active {\n\tz-index: 999;\n\tborder-color: #6A6A6A;\n\t-webkit-box-shadow: 15px 15px 20px rgba(0,0, 0, 0.4);\n\t-moz-box-shadow: 15px 15px 20px rgba(0,0, 0, 0.4);\n\tbox-shadow: 15px 15px 20px rgba(0,0, 0, 0.4);\n\t-webkit-transform: rotate(0deg) scale(1.05);\n\t-moz-transform: rotate(0deg) scale(1.05);\n\ttransform: rotate(0deg) scale(1.05);\n}\n\nYou\u2019ll notice we are now giving the transform property another transform function: scale, which takes increases the size by the specified factor. Other things you can do with transform include skewing, translating or you can go mad creating your own transforms with a matrix.\n\nThe box-shadow has both its offset and blur radius increased dramatically, and is darkened using the alpha channel of the rgba colour.\n\nAnd because we want the effects to all animate smoothly, we pass a value of all to the -webkit-transition property, ensuring that any changed property on that link will be animated.\n\nDemo 5 is the finished example, bringing everything nicely together.\n\nCSS transitions and transforms are a great example of progressive enrichment, which means improving the experience for a portion of the audience without negatively affecting other users. They are also a lot of fun to play with!\n\nFurther reading\n\n\n\t-moz-transform \u2013 the mozilla developer center has a comprehensive explanation of transform that also applies to -webkit-transform and transform.\n\tCSS: Animation Using CSS Transforms \u2013 this is a good, more indepth tutorial on animations.\n\tCSS Animation \u2013 the Safari blog explains the usage of -webkit-transform.\n\tDinky pocketbooks with transform \u2013 another use for transforms, create your own printable pocketbook.\n\tA while back, Simon wrote a little bookmarklet to spin the entire page\u2026 warning: this will spin the entire page.", "year": "2009", "author": "Natalie Downe", "author_slug": "nataliedowne", "published": "2009-12-14T00:00:00+00:00", "url": "https://24ways.org/2009/going-nuts-with-css-transitions/", "topic": "code"}
{"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": 292, "title": "Watch Your Language!", "contents": "I\u2019m bilingual. My first language is French. I learned English in my early 20s. Learning a new language later in life meant that I was able to observe my thought processes changing over time. It made me realize that some concepts can\u2019t be expressed in some languages, while other languages express these concepts with ease.\nIt also helped me understand the way we label languages. English: business. French: romance. Here\u2019s an example of how words, or the absence thereof, can affect the way we think:\nIn French we love everything. There\u2019s no straightforward way to say we like something, so we just end up loving everything. I love my sisters, I love broccoli, I love programming, I love my partner, I love doing laundry (this is a lie), I love my mom (this is not a lie). I love, I love, I love. It\u2019s no wonder French is considered romantic. When I first learned English I used the word love rather than like because I hadn\u2019t grasped the difference. Needless to say, I\u2019ve scared away plenty of first dates!\nLearning another language made me realize the limitations of my native language and revealed concepts I didn\u2019t know existed. Without the nuances a given language provides, we fail to express what we really think. The absence of words in our vocabulary gets in the way of effectively communicating and considering ideas.\nWhen I lived in Montr\u00e9al, most people in my circle spoke both French and English. I could switch between them when I could more easily express an idea in one language or the other. I liked (or should I say loved?) those conversations. They were meaningful. They were efficient.\n\nI\u2019m quadrilingual. I code in Ruby, HTML/CSS, JavaScript, Python. In the past couple of years I have been lucky enough to write code in these languages at a massive scale. In learning Ruby, much like learning English, I discovered the strengths and limitations of not only the languages I knew but the language I was learning. It taught me to choose the right tool for the job.\nWhen I started working at Shopify, making a change to a view involved copy/pasting HTML and ERB from one view to another. The CSS was roughly structured into modules, but those modules were not responsive to different screen sizes. Our HTML was complete mayhem, and we didn\u2019t consider accessibility. All this made editing views a laborious process.\nGrep. Replace all. Test. Ship it. Repeat.\nThis wasn\u2019t sustainable at Shopify\u2019s scale, so the newly-formed front end team was given two missions:\n\nMake the app responsive (AKA Let\u2019s Make This Thing Responsive ASAP)\nMake the view layer scalable and maintainable (AKA Let\u2019s Build a Pattern Library\u2026 in Ruby)\n\nLet\u2019s make this thing responsive ASAP\nThe year was 2015. The Shopify admin wasn\u2019t mobile friendly. Our browser support was set to IE10. We had the wind in our sails. We wanted to achieve complete responsiveness in the shortest amount of time. Our answer: container queries.\nIt seemed like the obvious decision at the time. We would be able to set rules for each component in isolation and the component would know how to lay itself out on the page regardless of where it was rendered. It would save us a ton of development time since we wouldn\u2019t need to change our markup, it would scale well, and we would achieve complete component autonomy by not having to worry about page layout. By siloing our components, we were going to unlock the ultimate goal of componentization, cutting the tie to external dependencies. We were cool.\nWriting the JavaScript handling container queries was my first contribution to Shopify. It was a satisfying project to work on. We could drop our components in anywhere and they would magically look good. It took us less than a couple weeks to push this to production and make our app mostly responsive.\nBut with time, it became increasingly obvious that this was not as performant as we had hoped. It wasn\u2019t performant at all. Components would jarringly jump around the page before settling in on first paint.\nIt was only when we started using the flex-wrap: wrap CSS property to build new components that we realized we were not using the right language for the job. So we swapped out JavaScript container queries for CSS flex-wrapping. Even though flex wasn\u2019t yet as powerful as we wanted it to be, it was still a good compromise. Our components stayed independent of the window size but took much less time to render. Best of all: they used CSS instead of relying on JavaScript for layout.\nIn other words: we were using the wrong language to express our layout to the browser, when another language could do it much more simply and elegantly.\nLet\u2019s build a pattern library\u2026 in Ruby\nIn order to make our view layer maintainable, we chose to build a comprehensive library of helpers. This library would generate our markup from a single source of truth, allowing us to make changes system-wide, in one place. No. More. Grepping.\nWhen I joined Shopify it was a Rails shop freshly wounded by a JavaScript framework (See: Batman.js). JavaScript was like Voldemort, the language that could not be named. Because of this baggage, the only way for us to build a pattern library that would get buyin from our developers was to use Rails view helpers. And for many reasons using Ruby was the right choice for us. The time spent ramping developers up on the new UI Components would be negligible since the Ruby API felt familiar. The transition would be simple since we didn\u2019t have to introduce any new technology to the stack. The components would be fast since they would be rendered on the server. We had a plan.\nWe put in place a set of Rails tools to make it easy to build components, then wrote a bunch of sweet, sweet components using our shiny new tools. To document our design, content and front end patterns we put together an interactive styleguide to demonstrate how every component works. Our research and development department loved it (and still do)! We continue to roll out new components, and generally the project has been successful, though it has had its drawbacks.\nSince the Shopify admin is mostly made up of a huge number of forms, most of the content is static. For this reason, using server-rendered components didn\u2019t seem like a problem at the time. With new app features increasing the amount of DOM manipulation needed on the client side, our early design decisions mean making requests to the server for each re-paint. This isn\u2019t going to cut it.\nI don\u2019t know the end of this story, because we haven\u2019t written it yet. We\u2019ve been exploring alternatives to our current system to facilitate the rendering of our components on the client, including React, Vue.js, and Web Components, but we haven\u2019t determined the winner yet. Only time (and data gathering) will tell.\nRuby is great but it doesn\u2019t speak the browser\u2019s language efficiently. It was not the right language for the job.\n\nLearning a new spoken language has had an impact on how I write code. It has taught me that you don\u2019t know what you don\u2019t know until you have the language to express it. Understanding the strengths and limitations of any programming language is fundamental to making good design decisions. At the end of the day, you make the best choices with the information you have. But if you still feel like you\u2019re unable to express your thoughts to the fullest with what you know, it might be time to learn a new language.", "year": "2016", "author": "Annie-Claude C\u00f4t\u00e9", "author_slug": "annieclaudecote", "published": "2016-12-10T00:00:00+00:00", "url": "https://24ways.org/2016/watch-your-language/", "topic": "code"}
{"rowid": 106, "title": "Checking Out: Progress Meters", "contents": "It\u2019s the holiday season, so you know what that means: online shopping! When I started developing Web sites back in the 90s, many of my first clients were small local shops wanting to sell their goods online, so I developed many a checkout system. And because of slow dial-up speeds back then, informing the user about where they were in the checkout process was pretty important.\n\nEven though we\u2019re (mostly) beyond the dial-up days, informing users about where they are in a flow is still important. In usability tests at the companies I\u2019ve worked at, I\u2019ve seen time and time again how not adequately informing the user about their state can cause real frustration. This is especially true for two sets of users: mobile users and users of assistive devices, in particular, screen readers.\n\nThe progress meter is a very common design solution used to indicate to the user\u2019s state within a flow. On the design side, much effort may go in to crafting a solution that is as visually informative as possible. On the development side, however, solutions range widely. I\u2019ve checked out the checkouts at a number of sites and here\u2019s what I\u2019ve found when it comes to progress meters: they\u2019re sometimes inaccessible and often confusing or unhelpful \u2014 all because of the way in which they\u2019re coded. For those who use assistive devices or text-only browsers, there must be a better way to code the progress meter \u2014 and there is.\n\n(Note: All code samples are from live sites but have been tweaked to hide the culprits\u2019 identities.)\n\nHow not to make progress\n\nA number of sites assemble their progress meters using non- or semi-semantic markup and images with no alternate text. On text-only browsers (like my mobile phone) and to screen readers, this looks and reads like chunks of content with no context given.\n\n<div id=\"progress\">\n\t<img src=\"icon_progress_1a.gif\" alt=\"\">\n\t<em>Shipping information</em>\n\t<img src=\"icon_progress_arrow.gif\" alt=\"\">\n\t<img src=\"icon_progress_2a.gif\" alt=\"\">\n\t<em>Payment information</em>\n\t<img src=\"icon_progress_arrow.gif\" alt=\"\" class=\"progarrow\">\n\t<img src=\"icon_progress_3b.gif\" alt=\"\">\n\t<strong>Place your order</strong>\n</div>\n\nIn the above example, the third state, \u201cPlace your order\u201d, is the current state. But a screen reader may not know that, and my cell phone only displays \"Shipping informationPayment informationPlace your order\". Not good.\n\nIs this progress?\n\nOther sites present the entire progress meter as a graphic, like the following:\n\n\n\nNow, I have no problem with using a graphic to render a very stylish progress meter (my sample above is probably not the most stylish example, of course, but you understand my point). What becomes important in this case is the use of appropriate alternate text to describe the image. Disappointingly, sites today have a wide range of solutions, including using no alternate text. Check out these code samples which call progress meter images.\n\n<img src=\"checkout_step2.gif\" alt=\"\">\n\nI think we can all agree that the above is bad, unless you really don\u2019t care whether or not users know where they are in a flow.\n\n<img src=\"checkout_step2.gif\" alt=\"Shipping information - Payment information - Place your order\">\n\nThe alt text in the example above just copies all of the text found in the graphic, but it doesn\u2019t represent the status at all. So for every page in the checkout, the user sees or hears the same text. Sure, by the second or third page in the flow, the user has figured out what\u2019s going on, but she or he had to think about it. I don\u2019t think that\u2019s good.\n\n<img src=\"checkout_step2.gif\" alt=\"Checkout: Payment information\">\n\nThe above probably has the best alternate text out of these examples, because the user at least understands that they\u2019re in the Checkout process, on the Place your order page. But going through the flow with alt text like this, the user doesn\u2019t know how many steps are in the flow.\n\nSemantic progress\n\nOf course, there are some sites that use an ordered list when marking up the progress meter. Hooray! Unfortunately, no text-only browser or screen reader would be able to describe the user\u2019s current state given this markup.\n\n<ol class=\"progressmeter\">\n\t<li class=\"one current\">shipping information</li>\n\t<li class=\"two\">payment information</li>\n\t<li class=\"three\">place your order</li>\n</ol>\n\nWithout CSS enabled, the above is rendered as follows:\n\n\n\nProgress at last\n\nWe all know that semantic markup makes for the best foundation, so we\u2019ll start with the markup found above. In order to make the state information accessible, let\u2019s add some additional text in paragraph and span elements.\n\n<div class=\"progressmeter\">\n\t<p>There are three steps in this checkout process.</p>\n\t<ol>\n\t\t<li class=\"one\"><span>Enter your</span> shipping information</li>\n\t\t<li class=\"two\"><span>Enter your</span> payment information</li>\n\t\t<li class=\"three\"><span>Review details and</span> place your order</li>\n\t</ol>\n</div>\n\nAdd on some simple CSS to hide the paragraph and spans, and arrange the list items on a single line with a background image to represent the large number, and this is what you\u2019ll get:\n\n \n\tThere are three steps in this checkout process.\n\t\n\t\tEnter your shipping information\n\t\tEnter your payment information\n\t\tReview details and place your order\n\t\n \n\nTo display and describe a state as active, add the class \u201ccurrent\u201d to one of the list items. Then change the hidden content such that it better describes the state to the user.\n\n<div class=\"progressmeter\">\n\t<p>There are three steps in this checkout process.</p>\n\t<ol>\n\t\t<li class=\"one current\"><span>You are currently entering your</span> shipping information</li>\n\t\t<li class=\"two\"><span>In the next step, you will enter your</span> payment information</li>\n\t\t<li class=\"three\"><span>In the last step, you will review the details and</span> place your order</li>\n\t</ol>\n</div>\n\nThe end result is an attractive progress meter that gives much greater semantic and contextual information.\n\n \n\tThere are three steps in this checkout process.\n\t\n\t\tYou are currently entering your shipping information\n\t\tIn the next step, you will enter your payment information\n\t\tIn the last step, you will review the details and place your order\n\t\n \n\nFor example, the above example renders in a text-only browser as follows:\n\n \n\tThere are three steps in this checkout process.\n\t\n\t\tYou are currently entering your shipping information\n\t\tIn the next step, you will enter your payment information\n\t\tIn the last step, you will review the details and place your order\n\t\n \n\nAnd the screen reader I use for testing announces the following:\n\n \n\tThere are three steps in this checkout process. List of three items. You are currently entering your shipping information. In the next step, you will enter your payment information. In the last step, you will review the details and place your order. List end.\n \n\nHere\u2019s a sample code page that summarises this approach.\n\nHappy frustration-free online shopping with this improved progress meter!", "year": "2008", "author": "Kimberly Blessing", "author_slug": "kimberlyblessing", "published": "2008-12-12T00:00:00+00:00", "url": "https://24ways.org/2008/checking-out-progress-meters/", "topic": "ux"}
{"rowid": 258, "title": "Mistletoe Offline", "contents": "It\u2019s that time of year, when we gather together as families to celebrate the life of the greatest person in history. This man walked the Earth long before us, but he left behind words of wisdom. Those words can guide us every single day, but they are at the forefront of our minds during this special season.\nI am, of course, talking about Murphy, and the golden rule he gave unto us:\n\nAnything that can go wrong will go wrong.\n\nSo true! I mean, that\u2019s why we make sure we\u2019ve got nice 404 pages. It\u2019s not that we want people to ever get served a File Not Found message, but we acknowledge that, despite our best efforts, it\u2019s bound to happen sometime. Murphy\u2019s Law, innit?\nBut there are some Murphyesque situations where even your lovingly crafted 404 page won\u2019t help. What if your web server is down? What if someone is trying to reach your site but they lose their internet connection? These are all things than can\u2014and will\u2014go wrong.\nI guess there\u2019s nothing we can do about those particular situations, right?\nWrong!\nA service worker is a Murphy-battling technology that you can inject into a visitor\u2019s device from your website. Once it\u2019s installed, it can intercept any requests made to your domain. If anything goes wrong with a request\u2014as is inevitable\u2014you can provide instructions for the browser. That\u2019s your opportunity to turn those server outage frowns upside down. Take those network connection lemons and make network connection lemonade.\nIf you\u2019ve got a custom 404 page, why not make a custom offline page too?\nGet your server in order\nStep one is to make \u2026actually, wait. There\u2019s a step before that. Step zero. Get your site running on HTTPS, if it isn\u2019t already. You won\u2019t be able to use a service worker unless everything\u2019s being served over HTTPS, which makes sense when you consider the awesome power that a service worker wields.\nIf you\u2019re developing locally, service workers will work fine for localhost, even without HTTPS. But for a live site, HTTPS is a must.\nMake an offline page\nAlright, assuming your site is being served over HTTPS, then step one is to create an offline page. Make it as serious or as quirky as is appropriate for your particular brand. If the website is for a restaurant, maybe you could put the telephone number and address of the restaurant on the custom offline page (unsolicited advice: you could also put this on the home page, you know). Here\u2019s an example of the custom offline page for this year\u2019s Ampersand conference.\nWhen you\u2019re done, publish the offline page at suitably imaginative URL, like, say /offline.html.\nPre-cache your offline page\nNow create a JavaScript file called serviceworker.js. This is the script that the browser will look to when certain events are triggered. The first event to handle is what to do when the service worker is installed on the user\u2019s device. When that happens, an event called install is fired. You can listen out for this event using addEventListener:\naddEventListener('install', installEvent => {\n// put your instructions here.\n}); // end addEventListener\nIn this case, you want to make sure that your lovingly crafted custom offline page is put into a nice safe cache. You can use the Cache API to do this. You get to create as many caches as you like, and you can call them whatever you want. Here, I\u2019m going to call the cache Johnny just so I can refer to it as JohnnyCache in the code:\naddEventListener('install', installEvent => {\n  installEvent.waitUntil(\n    caches.open('Johnny')\n    .then( JohnnyCache => {\n      JohnnyCache.addAll([\n       '/offline.html'\n      ]); // end addAll\n    }) // end open.then\n  ); // end waitUntil\n}); // end addEventListener\nI\u2019m betting that your lovely offline page is linking to a CSS file, maybe an image or two, and perhaps some JavaScript. You can cache all of those at this point:\naddEventListener('install', installEvent => {\n  installEvent.waitUntil(\n    caches.open('Johnny')\n    .then( JohnnyCache => {\n      JohnnyCache.addAll([\n       '/offline.html',\n       '/path/to/stylesheet.css',\n       '/path/to/javascript.js',\n           '/path/to/image.jpg'\n      ]); // end addAll\n    }) // end open.then\n  ); // end waitUntil\n}); // end addEventListener\nMake sure that the URLs are correct. If just one of the URLs in the list fails to resolve, none of the items in the list will be cached.\nIntercept requests\nThe next event you want to listen for is the fetch event. This is probably the most powerful\u2014and, let\u2019s be honest, the creepiest\u2014feature of a service worker. Once it has been installed, the service worker lurks on the user\u2019s device, waiting for any requests made to your site. Every time the user requests a web page from your site, a fetch event will fire. Every time that page requests a style sheet or an image, a fetch event will fire. You can provide instructions for what should happen each time:\naddEventListener('fetch', fetchEvent => {\n// What happens next is up to you!\n}); // end addEventListener\nLet\u2019s write a fairly conservative script with the following logic:\n\nWhenever a file is requested,\nFirst, try to fetch it from the network,\nBut if that doesn\u2019t work, try to find it in the cache,\nBut if that doesn\u2019t work, and it\u2019s a request for a web page, show the custom offline page instead.\n\nHere\u2019s how that translates into JavaScript:\n// Whenever a file is requested\naddEventListener('fetch', fetchEvent => {\n  const request = fetchEvent.request;\n  fetchEvent.respondWith(\n    // First, try to fetch it from the network\n    fetch(request)\n    .then( responseFromFetch => {\n      return responseFromFetch;\n    }) // end fetch.then\n    // But if that doesn't work\n    .catch( fetchError => {\n      // try to find it in the cache\n      caches.match(request)\n      .then( responseFromCache => {\n        if (responseFromCache) {\n         return responseFromCache;\n       // But if that doesn't work\n       } else {\n         // and it's a request for a web page\n         if (request.headers.get('Accept').includes('text/html')) {\n           // show the custom offline page instead\n           return caches.match('/offline.html');\n         } // end if\n       } // end if/else\n     }) // end match.then\n   }) // end fetch.catch\n  ); // end respondWith\n}); // end addEventListener\nI am fully aware that I may have done some owl-drawing there. If you need a more detailed breakdown of what\u2019s happening at each point in the code, I\u2019ve written a whole book for you. It\u2019s the perfect present for Murphymas.\nHook up your service worker script\nYou can publish your service worker script at /serviceworker.js but you still need to tell the browser where to look for it. You can do that using JavaScript. Put this in an existing JavaScript file that you\u2019re calling in to every page on your site, or add this in a script element at the end of every page\u2019s HTML:\nif (navigator.serviceWorker) {\n  navigator.serviceWorker.register('/serviceworker.js');\n}\nThat tells the browser to start installing the service worker, but not without first checking that the browser understands what a service worker is. When it comes to JavaScript, feature detection is your friend.\nYou might already have some JavaScript files in a folder like /assets/js/ and you might be tempted to put your service worker script in there too. Don\u2019t do that. If you do, the service worker will only be able to handle requests made to for files within /assets/js/. By putting the service worker script in the root directory, you\u2019re making sure that every request can be intercepted.\nGo further!\nNicely done! You\u2019ve made sure that if\u2014no, when\u2014a visitor can\u2019t reach your website, they\u2019ll get your hand-tailored offline page. You have temporarily defeated the forces of chaos! You have briefly fought the tide of entropy! You have made a small but ultimately futile gesture against the inevitable heat-death of the universe!\nThis is just the beginning. You can do more with service workers.\nWhat if, every time you fetched a page from the network, you stored a copy of that page in a cache? Then if that person tries to reach that page later, but they\u2019re offline, you could show them the cached version.\nOr, what if instead of reaching out the network first, you checked to see if a file is in the cache first? You could serve up that cached version\u2014which would be blazingly fast\u2014and still fetch a fresh version from the network in the background to pop in the cache for next time. That might be a good strategy for images.\nSo many options! The hard part isn\u2019t writing the code, it\u2019s figuring out the steps you want to take. Once you\u2019ve got those steps written out, then it\u2019s a matter of translating them into JavaScript.\nInevitably there will be some obstacles along the way\u2014usually it\u2019s a misplaced curly brace or a missing parenthesis. Don\u2019t be too hard on yourself if your code doesn\u2019t work at first.

{"rowid": 278, "title": "Going Both Ways", "contents": "It\u2019s that time of the year again: Santa is getting ready to travel the world. Up until now, girls and boys from all over have sent in letters asking for what they want. I hope that Santa and his elves have\u2014unlike me\u2014learned more than just English.\n\nOn the Internet, those girls and boys want to participate in sharing their stories and videos of opening presents and of being with friends and family. Ah, yes, the wonders of user generated content. But more than that, people also want to be able to use sites in the language they know.\n\nWhile you and I might expect the text to read from left to right, not all languages do. Some go from right to left, such as Arabic and Hebrew. (Some also go from top to bottom, but for now, let\u2019s just worry about those first two directions!)\n\nIf we were building a site for girls and boys to send their letters to Santa, we need to consider having the interface in the language and direction that they prefer. On the elves\u2019 side, they may be viewing the site in one direction but reading the user generated content in the other direction. We need to build a site that supports bidirectional (or bidi) text.\n\nLet\u2019s take a look at some things to be aware of when it comes to building bidi interfaces.\n\nSetting the direction of the interface\n\nRight off the bat, we need to tell the browser what direction the text should be going in. To do this, we add the dir attribute to an HTML element and set it to either LTR (for left to right) or RTL (for right to left).\n\n<body dir=\"rtl\">\n\nYou can add the dir attribute to any element and it will set or change the direction for the content within that element. \n\n<body dir=\"ltr\">\n   Here is English Content.\n   <div dir=\"rtl\">\u0627\u0644\u0645\u0648\u0636\u0648\u0639</div>\n</body>\n\nYou can also set the direction via CSS.\n\n.rtl {\n    direction: rtl;\n    }\n\nIt\u2019s generally recommended that you don\u2019t use CSS to set the direction of the text. Text direction is an important part of the content that should be retained even in environments where the CSS may not be available or fails to load.\n\nHow things change with the direction attribute\n\nJust adding the dir attribute tells the browser to render the content within it differently. \n\n\n\nThe text aligns to the right of the page and, interestingly, punctuation appears at the left of the sentence. (We\u2019ll get to that in a little bit.) \n\nScrollbars in most browsers will appear on the left instead of the right. Webkit is the notable exception here which always shows the scrollbar on the right, no matter what the text direction is. Avoid having a design that has an expectation that the scrollbar will be in a specific place (and a specific size).\n\nChanging the order of text mid-way\n\nAs we saw in that previous example, the punctuation appeared at the beginning of the sentence instead of the end, even though the text was English. At Yahoo!, we have an interesting dilemma where the company name has punctuation in it. Therefore, when the name appears in the middle of (for example) Arabic text, the exclamation mark appears at the beginning of the word instead of the end.\n\n\n\nThere are two ways in which this problem can be solved:\n\n1. Use HTML around the left-to-right content, or\n\nTo solve the problem of the Yahoo! name in the midst of Arabic text, we can wrap a span around it and change the direction on that element.\n\n\n\n2. Use a text direction mark in the content.\n\nUnicode has two marks, U+200E and U+200F, that tell the browser that the text is in a particular direction. Placing this right after the punctuation will correct the placement.\n\nUsing the HTML entity:\nYahoo!\u200e\n\nTables\n\nThankfully, the cells of a data table also get reordered from right to left. Equally as nice, if you\u2019re using display:table, the content will still get reordered.\n\n\n\nCSS\n\nSo far, we\u2019ve seen that the dir attribute does a pretty decent job of getting content flowing in the direction that we need it. Unfortunately, there are huge swaths of design that is handled by CSS that the handy dir attribute has zero effect over.\n\nMany properties, like float or absolute positioning with left and right values, are unaffected and must be handled manually. Elements that were floated left must now by floated right. Left margins and paddings must now move to the right and the right margins and paddings must now move to the left.\n\nSince the browser won\u2019t handle this for us, we have a couple approaches that we can use:\n\nCSS Only\n\nWe can take advantage of the attribute selector to target CSS to apply in one direction or another.\n\n[dir=ltr] .module {\n\tfloat: left;\n\tmargin: 0 0 0 20px;\n}\n\n[dir=rtl] .module {\n\tfloat: right;\n\tmargin: 0 20px 0 0;\n}\n\nAs you can see from this example, both of the properties have been modified for the flipped interface. If your interface is rather complicated, you will have to create a lot of duplicate rules to have the site looking good in both directions while serving up a single stylesheet.\n\nCSSJanus\n\nGoogle has a tool called CSSJanus. It\u2019s a Python script that runs over the LTR versions of your CSS files and generates RTL versions. For the RTL version of the site, just serve up those CSS files instead of the LTR versions.\n\nThe script looks for keywords and value combinations and automatically swaps them so you don\u2019t have to. \n\nAt Yahoo!, CSSJanus was a huge help in speeding up our development of a bidi interface. We\u2019ve also made a number of improvements to the script to better handle border radius, background positioning, and gradients. We will be pushing those changes back into the CSSJanus project. \n\n\n\nBackground Images\n\nBackground images, especially for things like CSS sprites, also raise an interesting dilemma. Background images are positioned relative to the left of the element. In a flipped interface, however, we need to position it relative to the right. An icon that would be to the left of some text will now need to appear on the right.\n\n\n\nIf the x position of the background is percentage-based, then it\u2019s fairly easy to swap the values. 0 becomes 100%, 10% becomes 90% and so on. If the x position is pixel-based, then we\u2019re in a bit of a pickle. There\u2019s no way to say that the image should be a certain number of pixels from the right.\n\nTherefore, you\u2019ll need to ensure that any background image that needs to be swapped should be percentage-based. (99.9% of the the time, the background position will need to be 0 so that it can be changed to 100% for RTL.)\n\nIf you\u2019re taking an existing implementation, background positioning will likely be the biggest hurdle you\u2019ll have to overcome in swapping your interface around. If you make sure your x position is always percentage-based from the beginning, you\u2019ll have a much smoother process ahead of you!\n\nFlipping Images\n\nThis is a more subtle point and one where you\u2019ll really want an expert with the region to weigh in on. In RTL interfaces, users may expect certain icons to also be flipped. Pencil icons that skew to the right in LTR interfaces might need to be swapped to skew to the left, instead. Chat bubbles that come from the left will need to come from the right.\n\nThe easiest way to handle this is to create new images. Name the LTR versions with -ltr in the name and name the RTL versions with -rtl in the name. CSSJanus will automatically rename all file references from -ltr to -rtl.\n\nThe Future\n\nThankfully, those within the W3C recognize that CSS should be more agnostic. As a result, they\u2019ve begun introducing new properties that allow the browser to manage the swapping from left to right for us.\n\nThe CSS3 specification for backgrounds allows for the background-position to be relative to other corners other than the top left by specifying keywords before each position.\n\nThis will position the background 5px from the bottom right of the element.\n\nbackground-position: right 5px bottom 5px;\n\nOpera 11.60 is currently the only browser that supports this syntax.\n\nFor margin and padding, we have margin-start and margin-end. In LTR interfaces, margin-start would be the same as margin-left and in RTL interfaces, margin-start would be the same as margin-right. \n\nFirefox and Webkit support these but with vendor prefixes right now:\n\n-webkit-margin-start: 20px;\n-moz-margin-start: 20px;\n\nIn the CSS3 Images working draft specification, there\u2019s an image() property that allows us to specify image fallbacks and whether those fallbacks are for LTR or RTL interfaces.\n\nbackground: image('sprite.png' ltr, 'sprite-rtl.png' rtl);\n\nUnfortunately, no browser supports this yet but it\u2019s nice to be able to dream of how much easier this will be in the future!\n\nHo Ho Ho\n\nHopefully, after all of this, you\u2019re full of cheer knowing that you\u2019re well on your way to creating interfaces that can go both ways!", "year": "2011", "author": "Jonathan Snook", "author_slug": "jonathansnook", "published": "2011-12-19T00:00:00+00:00", "url": "https://24ways.org/2011/going-both-ways/", "topic": "ux"}
{"rowid": 64, "title": "Being Responsive to the Small Things", "contents": "It\u2019s that time of the year again to trim the tree with decorations. Or maybe a DOM tree?\nAny web page is made of HTML elements that lay themselves out in a tree structure. We start at the top and then have multiple branches with branches that branch out from there. \n\nTo decorate our tree, we use CSS to specify which branches should receive the tinsel we wish to adorn upon it. It\u2019s all so lovely.\nIn years past, this was rather straightforward. But these days, our trees need to be versatile. They need to be responsive!\nResponsive web design is pretty wonderful, isn\u2019t it? Based on our viewport, we can decide how elements on the page should change their appearance to accommodate various constraints using media queries.\nClearleft have a delightfully clean and responsive site\nAlas, it\u2019s not all sunshine, lollipops, and rainbows. \nWith complex layouts, we may have design chunks \u2014 let\u2019s call them components \u2014 that appear in different contexts. Each context may end up providing its own constraints on the design, both in its default state and in its possibly various responsive states.\n\nMedia queries, however, limit us to the context of the entire viewport, not individual containers on the page. For every container our component lives in, we need to specify how to rearrange things in that context. The more complex the system, the more contexts we need to write code for.\n@media (min-width: 800px) {\n  .features > .component { }\n  .sidebar > .component {}\n  .grid > .component {}\n}\nEach new component and each new breakpoint just makes the entire system that much more difficult to maintain. \n@media (min-width: 600px) {\n  .features > .component { }\n  .grid > .component {}\n}\n\n@media (min-width: 800px) {\n  .features > .component { }\n  .sidebar > .component {}\n  .grid > .component {}\n}\n\n@media (min-width: 1024px) {\n  .features > .component { }\n}\nEnter container queries\nContainer queries, also known as element queries, allow you to specify conditional CSS based on the width (or maybe height) of the container that an element lives in. In doing so, you no longer have to consider the entire page and the interplay of all the elements within. \nWith container queries, you\u2019ll be able to consider the breakpoints of just the component you\u2019re designing. As a result, you end up specifying less code and the components you develop have fewer dependencies on the things around them. (I guess that makes your components more independent.)\nAwesome, right?\nThere\u2019s only one catch.\nBrowsers can\u2019t do container queries. There\u2019s not even an official specification for them yet. The Responsive Issues (n\u00e9e Images) Community Group is looking into solving how such a thing would actually work. \nSee, container queries are tricky from an implementation perspective. The contents of a container can affect the size of the container. Because of this, you end up with troublesome circular references. \nFor example, if the width of the container is under 500px then the width of the child element should be 600px, and if the width of the container is over 500px then the width of the child element should be 400px. \nCan you see the dilemma? When the container is under 500px, the child element resizes to 600px and suddenly the container is 600px. If the container is 600px, then the child element is 400px! And so on, forever. This is bad.\nI guess we should all just go home and sulk about how we just got a pile of socks when we really wanted the Millennium Falcon. \nOur saviour this Christmas: JavaScript\nThe three wise men \u2014 Tim Berners-Lee, H\u00e5kon Wium Lie, and Brendan Eich \u2014 brought us the gifts of HTML, CSS, and JavaScript. \nTo date, there are a handful of open source solutions to fill the gap until a browser implementation sees the light of day.\n\nElementary by Scott Jehl\nElementQuery by Tyson Matanich\nEQ.js by Sam Richards\nCSS Element Queries from Marcj\n\nUsing any of these can sometimes feel like your toy broke within ten minutes of unwrapping it.\nEach take their own approach on how to specify the query conditions. For example, Elementary, the smallest of the group, only supports min-width declarations made in a :before selector.\n.mod-foo:before {\n  content: \u201c300 410 500\u201d;\n}\nThe script loops through all the elements that you specify, reading the content property and then setting an attribute value on the HTML element, allowing you to use CSS to style that condition. \n.mod-foo[data-minwidth~=\"300\"] {\n  background: blue;\n}\nTo get the script to run, you\u2019ll need to set up event handlers for when the page loads and for when it resizes. \nwindow.addEventListener( \"load\", window.elementary, false );\nwindow.addEventListener( \"resize\", window.elementary, false );\nThis works okay for static sites but breaks down on pages where elements can expand or contract, or where new content is dynamically inserted.\nIn the case of EQ.js, the implementation requires the creation of the breakpoints in the HTML. That means that you have implementation details in HTML, JavaScript, and CSS. (Although, with the JavaScript, once it\u2019s in the build system, it shouldn\u2019t ever be much of a concern unless you\u2019re tracking down a bug.)\nAnother problem you may run into is the use of content delivery networks (CDNs) or cross-origin security issues. The ElementQuery and CSS Element Queries libraries need to be able to read the CSS file. If you are unable to set up proper cross-origin resource sharing (CORS) headers, these libraries won\u2019t help.\nAt Shopify, for example, we had all of these problems. The admin that store owners use is very dynamic and the CSS and JavaScript were being loaded from a CDN that prevented the JavaScript from reading the CSS. \nTo go responsive, the team built their own solution \u2014 one similar to the other scripts above, in that it loops through elements and adds or removes classes (instead of data attributes) based on minimum or maximum width.\nThe caveat to this particular approach is that the declaration of breakpoints had to be done in JavaScript. \n  elements = [\n    { \u2018module\u2019: \u201c.carousel\u201d, \u201cclassName\u201d:\u2019alpha\u2019, minWidth: 768, maxWidth: 1024 },\n    { \u2018module\u2019: \u201c.button\u201d, \u201cclassName\u201d:\u2019beta\u2019, minWidth: 768, maxWidth: 1024 } ,\n    { \u2018module\u2019: \u201c.grid\u201d, \u201cclassName\u201d:\u2019cappa\u2019, minWidth: 768, maxWidth: 1024 }\n  ]\nWith that done, the script then had to be set to run during various events such as inserting new content via Ajax calls. This sometimes reveals itself in flashes of unstyled breakpoints (FOUB). An unfortunate side effect but one largely imperceptible.\nUsing this approach, however, allowed the Shopify team to make the admin responsive really quickly. Each member of the team was able to tackle the responsive story for a particular component without much concern for how all the other components would react. \n\nEach element responds to its own breakpoint that would amount to dozens of breakpoints using traditional breakpoints. This approach allows for a truly fluid and adaptive interface for all screens.\nChristmas is over\nI wish I were the bearer of greater tidings and cheer. It\u2019s not all bad, though.

Source: Derek Bruff\n\nI\u2019ve been fortunate to work with Simply Accessible to redesign not just their website, but their entire brand. Although the new site won\u2019t be launching until the new year, we\u2019re excited to let you peek under the tree and share a few treats as a case study into how we tackled colour accessibility in our project workflow. Don\u2019t worry\u2014we won\u2019t tell Santa!\n\nCreate a colour game plan\n\nA common misconception about accessibility is that meeting compliance requirements hinders creativity and beautiful design\u2014but we beg to differ. Unfortunately, like many company websites and internal projects, Simply Accessible has spent so much time helping others that they had not spent enough time helping themselves to show the world who they really are. This was the perfect opportunity for them to practise what they preached.\n\nAfter plenty of research and brainstorming, we decided to evolve the existing Simply Accessible brand. Or, rather, salvage what we could. There was no established logo to carry into the new design (it was a stretch to even call it a wordmark), and the Helvetica typography across the site lacked any character. The only recognizable feature left to work with was colour. It was a challenge, for sure: the oranges looked murky and brown, and the blues looked way too corporate for a company like Simply Accessible. We knew we needed to inject a lot of personality.\n\nThe old Simply Accessible website and colour palette.\n\nAfter an audit to round up every colour used throughout the site, we dug in deep and played around with some ideas to bring some new life to this palette. \n\nChoose effective colours\n\nWhether you\u2019re starting from scratch or evolving an existing brand, the first step to having an effective and legible palette begins with your colour choices. While we aren\u2019t going to cover colour message and meaning in this article, it\u2019s important to understand how to choose colours that can be used to create strong contrast\u2014one of the most important ways to create hierarchy, focus, and legibility in your design.\n\nThere are a few methods of creating effective contrast.\n\nLight and dark colours\n\nThe contrast that exists between light and dark colours is the most important attribute when creating effective contrast.\n\nTry not to use colours that have a similar lightness next to each other in a design.\n\n\n\nThe red and green colours on the left share a similar lightness and don\u2019t provide enough contrast on their own without making some adjustments. Removing colour and showing the relationship in greyscale reveals that the version on the right is much more effective. \n\nIt\u2019s important to remember that red and green colour pairs cause difficulty for the majority of colour-blind people, so they should be avoided wherever possible, especially when placed next to each other. \n\nComplementary contrast\n\n\n\nEffective contrast can also be achieved by choosing complementary colours (other than red and green), that are opposite each other on a colour wheel.\n\nThese colour pairs generally work better than choosing adjacent hues on the wheel.\n\nCool and warm contrast\n\nContrast also exists between cool and warm colours on the colour wheel.\n\nImagine a colour wheel divided into cool colours like blues, purples, and greens, and compare them to warm colours like reds, oranges and yellows.\n\n\n\nChoosing a dark shade of a cool colour, paired with a light tint of a warm colour will provide better contrast than two warm colours or two cool colours. \n\nDevelop colour concepts\n\nAfter much experimentation, we settled on a simple, two-colour palette of blue and orange, a cool-warm contrast colour scheme. We added swatches for call-to-action messaging in green, error messaging in red, and body copy and form fields in black and grey. Shades and tints of blue and orange were added to illustrations and other design elements for extra detail and interest.\n\nFirst stab at a new palette.\n\nWe introduced the new palette for the first time on an internal project to test the waters before going full steam ahead with the website. It gave us plenty of time to get a feel for the new design before sharing it with the public.\n\nPutting the test palette into practice with an internal report\n\nIt\u2019s important to be open to changes in your palette as it might need to evolve throughout the design process. Don\u2019t tell your client up front that this palette is set in stone. If you need to tweak the colour of a button later because of legibility issues, the last thing you want is your client pushing back because it\u2019s different from what you promised.\n\nAs it happened, we did tweak the colours after the test run, and we even adjusted the logo\u2014what looked great printed on paper looked a little too light on screens.\n\nConsider how colours might be used\n\nDon\u2019t worry if you haven\u2019t had the opportunity to test your palette in advance. As long as you have some well-considered options, you\u2019ll be ready to think about how the colour might be used on the site or app. \n\nObviously, in such early stages it\u2019s unlikely that you\u2019re going to know every element or feature that will appear on the site at launch time, or even which design elements could be introduced to the site later down the road. There are, of course, plenty of safe places to start.\n\nFor Simply Accessible, I quickly mocked up these examples in Illustrator to get a handle on the elements of a website where contrast and legibility matter the most: text colours and background colours. While it\u2019s less important to consider the contrast of decorative elements that don\u2019t convey essential information, it\u2019s important for a reader to be able to discern elements like button shapes and empty form fields.\n\nA basic list of possible colour combinations that I had in mind for the Simply Accessible website\n\nRun initial tests\n\nOnce these elements were laid out, I manually plugged in the HTML colour code of each foreground colour and background colour on Lea Verou\u2019s Contrast Checker. I added the results from each colour pair test to my document so we could see at a glance which colours needed adjustment or which colours wouldn\u2019t work at all.\n\nNote: Read more about colour accessibility and contrast requirements\n\n\n\n\n\nAs you can see, a few problems were revealed in this test. To meet the minimum AA compliance, we needed to slightly darken the green, blue, and orange background colours for text\u2014an easy fix. A more complicated problem was apparent with the button colours. I had envisioned some buttons appearing over a blue background, but the contrast ratios were well under 3:1. Although there isn\u2019t a guide in WCAG for contrast requirements of two non-text elements, the ISO and ANSI standard for visible contrast is 3:1, which is what we decided to aim for.\n\nWe also checked our colour combinations in Color Oracle, an app that simulates the most extreme forms of colour blindness. It confirmed that coloured buttons over blue backgrounds was simply not going to work. The contrast was much too low, especially for the more common deuteranopia and protanopia-type deficiencies.\n\nHow our proposed colour pairs could look to people with three types of colour blindness\n\nMake adjustments if necessary\n\n\n\nAs a solution, we opted to change all buttons to white when used over dark coloured backgrounds. In addition to increasing contrast, it also gave more consistency to the button design across the site instead of introducing a lot of unnecessary colour variants.\n\nPutting more work into getting compliant contrast ratios at this stage will make the rest of implementation and testing a breeze. When you\u2019ve got those ratios looking good, it\u2019s time to move on to implementation.\n\nImplement colours in style guide and prototype\n\nOnce I was happy with my contrast checks, I created a basic style guide and added all the colour values from my colour exploration files, introduced more tints and shades, and added patterned backgrounds. I created examples of every panel style we were planning to use on the site, with sample text, links, and buttons\u2014all with working hover states. Not only does this make it easier for the developer, it allows you to check in the browser for any further contrast issues.\n\n\n\n\n\nRun a final contrast check\n\nDuring the final stages of testing and before launch, it\u2019s a good idea to do one more check for colour accessibility to ensure nothing\u2019s been lost in translation from design to code. Unless you\u2019ve introduced massive changes to the design in the prototype, it should be fairly easy to fix any issues that arise, particularly if you\u2019ve stayed on top of updating any revisions in the style guide.\n\nOne of the more well-known evaluation tools, WAVE, is web-based and will work in any browser, but I love using Chrome\u2019s Accessibility Tools. Not only are they built right in to the Inspector, but they\u2019ll work if your site is password-protected or private, too.\n\nChrome\u2019s Accessibility Tools audit feature shows that there are no immediate issues with colour contrast in our prototype \n\nThe human touch\n\nFinally, nothing beats a good round of user testing. Even evaluation tools have their flaws. Although they\u2019re great at catching contrast errors for text and backgrounds, they aren\u2019t going to be able to find errors in non-text elements, infographics, or objects placed next to each other where discernible contrast is important. \n\n\n\nOur final palette, compared with our initial ideas, was quite different, but we\u2019re proud to say it\u2019s not just compliant, but shows Simply Accessible\u2019s true personality. Who knows, it may not be final at all\u2014there are so many opportunities down the road to explore and expand it further.\n\n\n\nAccessibility should never be an afterthought in a project. It\u2019s not as simple as adding alt text to images, or running your site through a compliance checker at the last minute and assuming that a pass means everything is okay. Considering how colour will be used during every stage of your project will help avoid massive problems before launch, or worse, launching with serious issues. \n\nIf you find yourself working on a personal project over the Christmas break, try integrating these checks into your workflow and make colour accessibility a part of your New Year\u2019s resolutions.", "year": "2014", "author": "Geri Coady", "author_slug": "gericoady", "published": "2014-12-22T00:00:00+00:00", "url": "https://24ways.org/2014/integrating-contrast-checks-in-your-web-workflow/", "topic": "design"}
{"rowid": 33, "title": "Five Ways to Animate Responsibly", "contents": "It\u2019s been two years since I wrote about \u201cFlashless Animation\u201d on this very site. Since then, animation has steadily begun popping up on websites, from sleek app-like user interfaces to interactive magazine-like spreads. It\u2019s an exciting time for web animation wonks, interaction developers, UXers, UI designers and a host of other acronyms! \n\nBut in our rush to experiment with animation it seems that we\u2019re having fewer conversations about whether or not we should use it, and more discussions about what we can do with it. We spend more time fretting over how to animate all the things at 60fps than we do devising ways to avoid incapacitating users with vestibular disorders.\n\nI love web animation. I live it. And I make adorably silly things with it that have no place on a self-respecting production website. I know it can be abused. We\u2019ve all made fun of Flash-turbation. But how quickly we forget the lessons we learned from that period of web design. Parallax scrolling effects may be the skip intro of this generation. Surely we have learned better in the sobering up period between Flash and the web animation API.\n\nSo here are five bits of advice we can use to pull back from the edge of animation abuse. With these thoughts in mind, we can make 2015 the year web animation came into its own. \n\nAnimate deliberately\n\nSadly, animation is considered decorative by the bulk of the web development community. UI designers and interaction developers know better, of course. But when I\u2019m teaching a workshop on animation for interaction, I know that my students face an uphill battle against decision makers who consider it nice to have, and tack it on at the end of a project, if at all. \n\nThis stigma is hard to shake. But it starts with us using animation deliberately or not at all. Poorly considered, tacked-on animation will often cause more harm than good. Users may complain that it\u2019s too slow or too fast, or that they have no idea what just happened.\n\nWhen I was at Chrome Dev Summit this year, I had the privilege to speak with Roma Sha, the UX lead behind Polymer\u2019s material design (with the wonderful animation documentation). I asked her what advice she\u2019d give to people using animation and transitions in their own designs. She responded simply: animate deliberately. If you cannot afford to slow down to think about animation and make well-informed and well-articulated decisions on behalf of the user, it is better that you not attempt it at all. Animation takes energy to perform, and a bad animation is worse than none at all. \n\nIt takes more than twelve principles\n\nWe always try to draw correlations between disparate things that spark our interest. Recently it feels like more and more people are putting the The Illusion of Life on their reading shelf next to Understanding Comics. These books give us so many useful insights from other industries. However, we should never mistake a website for a comic book or an animated feature film. Some of these concepts, while they help us see our work in a new light, can be more or less relevant to producing said work. \n\n\nThe illusion of life from cento lodigiani on Vimeo.\n\nI am specifically thinking of the twelve principles of animation put forth by Disney studio veterans in that great tome The Illusion of Life. These principles are very useful for making engaging, lifelike animation, like a ball bouncing or a squirrel scampering, or the physics behind how a lightbox should feel transitioning off a page. But they provide no direction at all for when or how something should be animated as part of a greater interactive experience, like how long a drop-down should take to fully extend or if a group of manipulable objects should be animated sequentially or as a whole.\n\nThe twelve principles are a great place to start, but we have so much more to learn. I\u2019ve documented at least six more functions of interactive animation that apply to web and app design. When thinking about animation, we should consider why and how, not just what, the physics. Beautiful physics mean nothing if the animation is superfluous or confusing.\n\nUseful and necessary, then beautiful\n\nThere is a Shaker saying: \u201cDon\u2019t make something unless it is both necessary and useful; but if it is both necessary and useful, don\u2019t hesitate to make it beautiful.\u201d When it comes to animation and the web, currently there is very little documentation about what makes it useful or necessary. We tend to focus more on the beautiful, the delightful, the aesthetic. And while aesthetics are important, they take a back seat to the user\u2019s overall experience. \n\n\n\nThe first time I saw the load screen for Pokemon Yellow on my Game Boy, I was enthralled.  By the sixth time, I was mashing the start button as soon as Game Freak\u2019s logo hit the screen. What\u2019s delightful and meaningful to us while working on a project is not always so for our users. And even when a purely delightful animation is favorably received, as with Pokemon Yellow\u2019s adorable opening screen, too many repetitions of the cutest but ultimately useless animation, and users start to resent it as a hindrance.\n\n \n\nIf an animation doesn\u2019t help the user in some way, by showing them where they are or how two elements on a page relate to each other, then it\u2019s using up battery juice and processing cycles solely for the purpose of delight. Hardly the best use of resources.\n\nRather than animating solely for the sake of delight, we should first be able to articulate two things the animation does for the user. As an example, take this menu icon from Finethought.com (found via Use Your Interface). The menu icon does two things when clicked: \n\n\n\tIt gives the user feedback by animating, letting the user know its been clicked.\n\tIt demonstrates its changed relationship to the page\u2019s content by morphing into a close button.\n\n\n\n\nAssuming we have two good reasons to animate something, there is no reason our third cannot be to delight the user. \n\nGo four times faster\n\nThere is a rule of thumb in the world of traditional animation which is applicable to web animation: however long you think your animation should last, take that time and halve it. Then halve it again! When we work on an animation for hours, our sense of time dilates. What seems fast to us is actually unbearably slow for most users. In fact, the most recent criticism from users of animated interfaces on websites seems to be, \u201cIt\u2019s so slow!\u201d A good animation is unobtrusive, and that often means running fast.\n\nWhen getting your animations ready for prime time, reduce those durations to 25% of their original speed: a four-second fade out should be over in one. \n\nInstall a kill switch\n\nNo matter how thoughtful and necessary an animation, there will be people who become physically sick from seeing it. For these people, we must add a way to turn off animations on the website. \n\nFortunately, web designers are already thinking of ways to empower users to make their own decisions about how they experience the web. As an example, this site for the animated film Little from the Fish Shop allows users to turn off most of the parallax effects. While it doesn\u2019t remove the animation entirely, this website does reduce the most nauseating of the animations. \t\n\n\n\n\n\nAnimation is a powerful tool in our web design arsenal. But we must take care: if we abuse animation it might get a bad reputation; if we underestimate it, it won\u2019t be prioritized. But if we wield it thoughtfully, use it where it is both necessary and useful, and empower users to turn it off, animation is a tool that will help us build things that are easier to use and more delightful for years to come.\n\nLet\u2019s make 2015 the year web animation went to work for users.", "year": "2014", "author": "Rachel Nabors", "author_slug": "rachelnabors", "published": "2014-12-14T00:00:00+00:00", "url": "https://24ways.org/2014/five-ways-to-animate-responsibly/", "topic": "ux"}
{"rowid": 246, "title": "Designing Your Site Like It\u2019s 1998", "contents": "It\u2019s 20 years to the day since my wife and I started Stuff & Nonsense, our little studio and my outlet for creative ideas on the web. To celebrate this anniversary\u2014and my fourteenth contribution to 24 ways\u2014 I\u2019d like to explain how I would\u2019ve developed a design for Planes, Trains and Automobiles, one of my favourite Christmas films.\nMy design for Planes, Trains and Automobiles is fixed at 800px wide.\nDeveloping a <frameset> framework\nI\u2019ll start by using frames to set up the framework for this new website. Frames are individual pages\u2014one for navigation, the other for my content\u2014pulled together to form a frameset. Space is limited on lower-resolution screens, so by using frames I can ensure my navigation always remains visible. I can include any number of frames inside a <frameset> element.\nI add two rows to my <frameset>; the first is for my navigation and is 50px tall, the second is for my content and will resize to fill any available space. As I don\u2019t want frame borders or any space between my frames, I set frameborder and framespacing attributes to 0:\n<frameset frameborder=\"0\" framespacing=\"0\" rows=\"50,*\">\n[\u2026]\n</frameset>\nNext I add the source of my two frame documents. I don\u2019t want people to be able to resize or scroll my navigation, so I add the noresize attribute to that frame:\n<frameset frameborder=\"0\" framespacing=\"0\" rows=\"50,*\">\n<frame noresize scrolling=\"no\" src=\"nav.html\">\n<frame src=\"content.html\">\n</frameset>\nI do want links from my navigation to open in the content frame, so I give each <frame> a name so I can specify where I want links to open:\n<frameset frameborder=\"0\" framespacing=\"0\" rows=\"50,*\">\n<frame name=\"navigation\" noresize scrolling=\"no\" src=\"nav.html\">\n<frame name=\"content\" src=\"content.html\">\n</frameset>\nThe framework for this website is simple as it contains only two horizontal rows. Should I need a more complex layout, I can nest as many framesets\u2014and as many individual documents\u2014as I need:\n<frameset rows=\"50,*\">\n <frame name=\"navigation\">\n <frameset cols=\"25%,*\">\n  <frame name=\"sidebar\">\n  <frame name=\"content\">\n </frameset>\n</frameset>\nLetterbox framesets were common way to deal with multiple screen sizes. In a letterbox, the central frameset had a fixed height and width, while the frames on the top, right, bottom, and left expanded to fill any remaining space.\nHandling older browsers\nSadly not every browser supports frames, so I should send a helpful message to people who use older browsers asking them to upgrade. Happily, I can do that using noframes content:\n<noframes>\n<body>\n<p>This page uses frames, but your browser doesn\u2019t support them. \n    Please upgrade your browser.</p>\n</body>\n</noframes>\nForcing someone back into a frame\nSometimes, someone may follow a link to a page from a portal or search engine, or they might attempt to open it in a new window or tab. If that page properly belongs inside a <frameset>, people could easily miss out on other parts of a design. This short script will prevent this happening and because it\u2019s vanilla Javascript, it doesn\u2019t require a library such as jQuery:\n<script type=\"text/javascript\">\nif (top == self) {\n  location = 'frameset.html';\n}\n</script>\n\nLaying out my page\nBefore starting my layout, I add a few basic background and colour styles. I must include these attributes in every page on my website:\n<body background=\"img/container.jpg\" bgcolor=\"#fef7fb\" \n    link=\"#245eab\" alink=\"#245eab\" vlink=\"#3c146e\" text=\"#000000\">\nI want absolute control over how people experience my design and don\u2019t want to allow it to stretch, so I first need a <table> which limits the width of my layout to 800px. The align attribute will keep this <table> in the centre of someone\u2019s screen:\n<table width=\"800\" align=\"center\">\n <tr>\n  <td>[\u2026]</td>\n </tr>\n</table>\nAlthough they were developed for displaying tabular information, the cells and rows which make up the <table> element make it ideal for the precise implementation of a design. I need several tables\u2014often nested inside each other\u2014to implement my design. These include tables for a banner and three rows of content:\n<table width=\"800\" align=\"center\">\n <table>[\u2026]</table>\n <table>\n  <table>\n   <table>[\u2026]</table>\n  </table>\n </table>\n <table>[\u2026]</table>\n <table>[\u2026]</table>\n</table>\nThe width of the first table\u2014used for my banner\u2014is fixed to match the logo it contains. As I don\u2019t need borders, padding, or spacing between these cells, I use attributes to remove them:\n<table border=\"0\" cellpadding=\"0\" cellspacing=\"0\" width=\"587\" align=\"center\">\n <tr>\n  <td><img src=\"logo.gif\" border=\"0\" width=\"587\" alt=\"Logo\"></td>\n </tr>\n</table>\nThe next table\u2014which contains the largest image, introduction, and a call-to-action\u2014is one of the most complex parts of my design, so I need to ensure its layout is pixel perfect. To do that I add an extra row at the top of this table and fill each of its cells with tiny transparent images:\n<tr>\n <td><img src=\"spacer.gif\" width=\"593\" height=\"1\"></td>\n <td><img src=\"spacer.gif\" width=\"207\" height=\"1\"></td>\n</tr>\nThe height and width of these \u201cshims\u201d or \u201cspacers\u201d is only 1px but they will stretch to any size without increasing their weight on the page. This makes them perfect for performant website development.\nFor the hero of this design, I splice up the large image into three separate files and apply each slice as a background to the table cells. I also match the height of those cells to the background images:\n<tr>\n <td background=\"slice-1.jpg\" height=\"473\">\u00a0</td>\n <td background=\"slice-2.jpg\" height=\"473\">[\u2026]</td>\n</tr>\n\n<tr>\n <td background=\"slice-3.jpg\" height=\"388\">\u00a0</td>\n</tr>\nI use tables and spacer images throughout the rest of this design to lay out the various types of content with perfect precision. For example, to add a single-pixel border around my two columns of content, I first apply a blue background to an outer table along with 1px of cellspacing, then simply nest an inner table\u2014this time with a white background\u2014inside it:\n<table border=\"0\" cellpadding=\"1\" cellspacing=\"0\">\n <tr>\n  <td>\n   <table bgcolor=\"#ffffff\" border=\"0\" cellpadding=\"0\" cellspacing=\"0\">\n[\u2026]\n   </table>\n  </td>\n </tr>\n</table>\nAdding details\nTables are fabulous tools for laying out a page, but they\u2019re also useful for implementing details on those pages. I can use a table to add a gradient background, rounded corners, and a shadow to the button which forms my \u201cBuy the DVD\u201d call-to-action. First, I splice my button graphic into three slices; two fixed-width rounded ends, plus a narrow gradient which stretches and makes this button responsive. Then, I add those images as backgrounds and use spacers to perfectly size my button:\n<table border=\"0\" cellpadding=\"0\" cellspacing=\"0\">\n <tr>\n  <td background=\"btn-1.jpg\" border=\"0\" height=\"48\" width=\"30\"><img src=\"spacer.gif\" width=\"30\" height=\"1\"></td>\n\n  <td background=\"btn-2.jpg\" border=\"0\" height=\"48\">\n   <center>\n    <a href=\"\" target=\"_blank\"><b>Buy the DVD</b></a>\n   </center>\n  </td>\n\n  <td background=\"btn-3.jpg\" border=\"0\" height=\"48\" width=\"30\"><img src=\"spacer.gif\" width=\"30\" height=\"1\"></td>\n </tr>\n</table>\nI use those same elements to add details to headlines and lists too. Adding a \u201cbullet\u201d to each item in a list needs only two additional table cells, a circular graphic, and a spacer:\n<table border=\"0\" cellpadding=\"0\" cellspacing=\"0\">\n <tr>\n  <td width=\"10\"><img src=\"li.gif\" border=\"0\" width=\"8\" height=\"8\">\u00a0</td>\n  <td><img src=\"spacer.gif\" width=\"10\" height=\"1\">\u00a0</td>\n  <td>Directed by John Hughes</td>\n </tr>\n</table>\nImplementing a typographic hierarchy\nSo far I\u2019ve explained how to use frames, tables, and spacers to develop a layout for my content, but what about styling that content? I use <font> elements to change the typeface from the browser\u2019s default to any font installed on someone\u2019s device:\n<font face=\"Arial\">Planes, Trains and Automobiles is a comedy film [\u2026]</font>\nTo adjust the size of those fonts, I use the size attribute and a value between the smallest (1) and the largest (7) where 3 is the browser\u2019s default. I use a size of 4 for this headline and 2 for the text which follows:\n<font face=\"Arial\" size=\"4\"><b>Steve Martin</b></font>\n\n<font face=\"Arial\" size=\"2\">An American actor, comedian, writer, producer, and musician.</font>\nWhen I need to change the typeface, perhaps from a sans-serif like Arial to a serif like Times New Roman, I must change the value of the face attribute on every element on all pages on my website.\nNB: I use as many <br> elements as needed to create space between headlines and paragraphs.\nView the final result (and especially the source.)\nMy modern day design for Planes, Trains and Automobiles.\nI can imagine many people reading this and thinking \u201cThis is terrible advice because we don\u2019t develop websites like this in 2018.\u201d That\u2019s true.\nWe have the ability to embed any number of web fonts into our products and websites and have far more control over type features, leading, ligatures, and sizes:\nfont-variant-caps: titling-caps;\nfont-variant-ligatures: common-ligatures;\nfont-variant-numeric: oldstyle-nums;\nGrid has simplified the implementation of even the most complex compound grid down to just a few lines of CSS:\nbody {\n  display: grid;\n  grid-template-columns: 3fr 1fr 2fr 2fr 1fr 3fr;\n  grid-template-rows: auto;\n  grid-column-gap: 2vw;\n  grid-row-gap: 1vh;\n}\nFlexbox has made it easy to develop flexible components such as navigation links:\nnav ul { display: flex; }\nnav li { flex: 1; }\nJust one line of CSS can create multiple columns of fluid type:\nmain { column-width: 12em; }\nCSS Shapes enable text to flow around irregular shapes including polygons:\n[src*=\"main-img\"] {\n  float: left;\n  shape-outside: polygon(\u2026);\n}\nToday, we wouldn\u2019t dream of using images and a table to add a gradient, rounded corners, and a shadow to a button or link, preferring instead:\n.btn {\n  background: linear-gradient(#8B1212, #DD3A3C);\n  border-radius: 1em;\n  box-shadow: 0 2px 4px 0 rgba(0,0,0,0.50), inset 0 -1px 1px 0 rgba(0,0,0,0.50);\n}\nCSS Custom Properties, feature and media queries, filters, pseudo-elements, and SVG; the list of advances in HTML, CSS, and other technologies goes on. So does our understanding of how best to use them by separating content, structure, presentation, and behaviour. As 2018 draws to a close, we\u2019re certain we know how to design and develop products and websites better than we did at the end of 1998.\nStrange as it might seem looking back, in 1998 we were also certain our techniques and technologies were the best for the job. That\u2019s why it\u2019s dangerous to believe with absolute certainty that the frameworks and tools we increasingly rely on today\u2014tools like Bootstrap, Bower, and Brunch, Grunt, Gulp, Node, Require, React, and Sass\u2014will be any more relevant in the future than <font> elements, frames, layout tables, and spacer images are today.\nI have no prediction for what the web will be like twenty years from now. However, I want to believe we\u2019ll build on what we\u2019ve learned during these past two decades about the importance of accessibility, flexibility, and usability, and that the mistakes we made while infatuated by technologies won\u2019t be repeated.\n\nHead over to my website if you\u2019d like to read about how I\u2019d implement my design for \u2018Planes, Trains and Automobiles\u2019 today.", "year": "2018", "author": "Andy Clarke", "author_slug": "andyclarke", "published": "2018-12-23T00:00:00+00:00", "url": "https://24ways.org/2018/designing-your-site-like-its-1998/", "topic": "code"}
