{"rowid": 86, "title": "Flashless Animation", "contents": "Animation in a Flashless world\n\nWhen I splashed down in web design four years ago, the first thing I wanted to do was animate a cartoon in the browser. I\u2019d been drawing comics for years, and I\u2019ve wanted to see them come to life for nearly as long. Flash animation was still riding high, but I didn\u2019t want to learn Flash. I wanted to learn JavaScript!\n\nSadly, animating with JavaScript was limiting and resource-intensive. My initial foray into an infinitely looping background did more to burn a hole in my CPU than amaze my friends (although it still looks pretty cool). And there was still no simple way to incorporate audio. The browser technology just wasn\u2019t there.\n\nThings are different now. CSS3 transitions and animations can do most of the heavy lifting and HTML5 audio can serve up the music and audio clips. You can do a lot without leaning on JavaScript at all, and when you lean on JavaScript, you can do so much more!\n\nIn this project, I\u2019m going to show you how to animate a simple walk cycle with looping audio. I hope this will inspire you to do something really cool and impress your friends. I\u2019d love to see what you come up with, so please send your creations my way at rachelnabors.com!\n\nNote: Because every browser wants to use its own prefixes with CSS3 animations, and I have neither the time nor the space to write all of them out, I will use the W3C standard syntaxes; that is, going prefix-less. You can implement them out of the box with something like Prefixfree, or you can add prefixes on your own. If you take the latter route, I recommend using Sass and Compass so you can focus on your animations, not copying and pasting.\n\nThe walk cycle\n\nWalk cycles are the \u201cHello world\u201d of animation. One of the first projects of animation students is to spend hours drawing dozens of frames to complete a simple loopable animation of a character walking.\n\nMost animators don\u2019t have to draw every frame themselves, though. They draw a few key frames and send those on to production animators to work on the between frames (or tween frames). This is meticulous, grueling work requiring an eye for detail and natural movement. This is also why so much production animation gets shipped overseas where labor is cheaper.\n\nLuckily, we don\u2019t have to worry about our frame count because we can set our own frames-per-second rate on the fly in CSS3. Since we\u2019re trying to impress friends, not animation directors, the inconsistency shouldn\u2019t be a problem. (Unless your friend is an animation director.)\n\nThis is a simple walk cycle I made of my comic character Tuna for my CSS animation talk at CSS Dev Conference this year:\n\n\n\nThe magic lies here:\n\nanimation: walk-cycle 1s steps(12) infinite;\n\nBreaking those properties down:\n\nanimation: <name> <duration> <timing-function> <iteration-count>;\n\nwalk-cycle is a simple @keyframes block that moves the background sprite on .tuna around:\n\n@keyframes walk-cycle {  \n    0% {background-position: 0 0; }\n    100% {background-position: 0 -2391px;}\n}\n\nThe background sprite has exactly twelve images of Tuna that complete a full walk cycle. We\u2019re setting it to cycle through the entire sprite every second, infinitely. So why isn\u2019t the background image scrolling down the .tuna container? It\u2019s all down to the timing function steps(). Using steps() let us tell the CSS to make jumps instead of the smooth transitions you\u2019d get from something like linear. Chris Mills at dev.opera wrote in his excellent intro to CSS3 animation :\n\n\n\tInstead of giving a smooth animation throughout, [steps()] causes the animation to jump between a set number of steps placed equally along the duration. For example, steps(10) would make the animation jump along in ten equal steps. There\u2019s also an optional second parameter that takes a value of start or end. steps(10, start) would specify that the change in property value should happen at the start of each step, while steps(10, end) means the change would come at the end.\n\n\n(Seriously, go read his full article. I\u2019m not going to touch on half the stuff he does because I cannot improve on the basics any more than he already has.)\n\nThe background\n\nA cat walking in a void is hardly an impressive animation and certainly your buddy one cube over could do it if he chopped up some of those cat GIFs he keeps using in group chat. So let\u2019s add a parallax background! Yes, yes, all web designers signed a peace treaty to not abuse parallax anymore, but this is its true calling\u2014treaty be damned.\n\n\n\nAnd to think we used to need JavaScript to do this! It\u2019s still pretty CPU intensive but much less complicated. We start by splitting up the page into different layers, .foreground, .midground, and .background. We put .tuna in the .midground.\n\n.background has multiple background images, all set to repeat horizontally:\n\nbackground-image:\n    url(background_mountain5.png),\n    url(background_mountain4.png),\n    url(background_mountain3.png),\n    url(background_mountain2.png),\n    url(background_mountain1.png);\nbackground-repeat: repeat-x;\n\nWith parallax, things in the foreground move faster than those in the background. Next time you\u2019re driving, notice how the things closer to you move out of your field of vision faster than something in the distance, like a mountain or a large building. We can imitate that here by making the background images on top (in the foreground, closer to us) wider than those on the bottom of the stack (in the distance).\n\nThe different lengths let us use one animation to move all the background images at different rates in the same interval of time:   \n\nanimation: parallax_bg linear 40s infinite;\n\nThe shorter images have less distance to cover in the same amount of time as the longer images, so they move slower.\n\n\n\nLet\u2019s have a look at the background\u2019s animation:\n\n@keyframes parallax_bg {  \n  0% {\n    background-position: -2400px 100%, -2000px 100%, -1800px 100%, -1600px 100%, -1200px 100%;\n  }\n  100% {\n    background-position: 0 100%, 0 100%, 0 100%, 0 100%, 0 100%;\n  }\n}\n\nAt 0%, all the background images are positioned at the negative value of their own widths. Then they start moving toward background-position: 0 100%. If we wanted to move them in the reverse direction, we\u2019d remove the negative values at 0% (so they would start at 2400px 100%, 2000px 100%, etc.). Try changing the values in the codepen above or changing background-repeat to none to see how the images play together.\n\n.foreground and .midground operate on the same principles, only they use single background images.\n\nThe music\n\nAfter finishing the first draft of my original walk cycle, I made a GIF with it and posted it on YTMND with some music from the movie Paprika, specifically the track \u201cThe Girl in Byakkoya.\u201d After showing it to some colleagues in my community, it became clear that this was a winning combination sure to drive away dresscode blues. So let\u2019s use HTML5 to get a clip of that music looping in there!\n\nWarning, there is sound. Please adjust your volume or apply headphones as needed.\n\n\n\nWe\u2019re using HTML5 audio\u2019s loop and autoplay abilities to automatically play and loop a sound file on page load:\n\n<audio loop autoplay>\n  <source src=\"http://music.com/clip.mp3\" />\n</audio>\n\nUnfortunately, you may notice there is a small pause between loops. HTML5 audio, thou art half-baked still. Let\u2019s hope one day the Web Audio API will be able to help us out, but until things improve, we\u2019ll have to hack our way around these shortcomings.\n\nTurns out there\u2019s a handy little script called seamlessLoop.js which we can use to patch this. Mind you, if we were really getting crazy with the Cheese Whiz, we\u2019d want to get out big guns like sound.js. But that\u2019d be overkill for a mere loop (and explaining the Web Audio API might bore, rather than impress your friends)!\n\nInstalling seamlessLoop.js will get rid of the pause, and now our walk cycle is complete.\n\n(I\u2019ve done some very rough sniffing to see if the browser can play MP3 files. If not, we fall back to using .ogg formatted clips (Opera and Firefox users, you\u2019re welcome).)\n\nReally impress your friends by adding a run cycle\n\nSo we have music, we have a walk cycle, we have parallax. It will be a snap to bring them all together and have a simple, endless animation. But let\u2019s go one step further and knock the socks off our viewers by adding a run cycle.\n\nThe run cycle\n\nTacking a run cycle on to our walk cycle will require a third animation sequence: a transitional animation of Tuna switching from walking to running. I have added all these to the sprite:\n\n\n\nLet\u2019s work on getting that transition down. We\u2019re going to use multiple animations on the same .tuna div, but we\u2019re going to kick them off at different intervals using animation-delay\u2014no JavaScript required! Isn\u2019t that magical?\n\n\n\nIt requires a wee bit of math (not much, it doesn\u2019t hurt) to line them up. We want to:\n\n\n\tLoop the walk animation twice\n\tPlay the transitional cycle once (it has a finite beginning and end perfectly drawn to pick up between the last frame of the walk cycle and the first frame of the run cycle\u2014no looping this baby)\n\tRUN FOREVER.\n\n\nUsing the pattern animation: <name> <duration> <timing-function> <delay> <iteration-count>, here\u2019s what that looks like:\n\nanimation:\n    walk-cycle 1s steps(12) 2,\n    walk-to-run .75s steps(12) 2s 1,\n    run-cycle .75s steps(13) 2.75s infinite;\n\nI played with the times to get make the movement more realistic. You may notice that the running animation looks smoother than the walking animation. That\u2019s because it has 13 keyframes running over .75 second instead of 12 running in one second. Remember, professional animation studios use super-high frame counts. This little animation isn\u2019t even up to PBS\u2019s standards!\n\nThe music: extended play with HTML5 audio sprites\n\nMy favorite part in the The Girl in Byakkoya is when the calm opening builds and transitions into a bouncy motif. I want to start with Tuna walking during the opening, and then loop the running and bounciness together for infinity.\n\n\n\tThe intro lasts for 24 seconds, so we set our 1 second walk cycle to run for 24 repetitions: \nwalk-cycle 1s steps(12) 24\n\tWe delay walk-to-run by 24 seconds so it runs for .75 seconds before\u2026\n\tWe play run-cycle at 24.75 seconds and loop it infinitely\n\n\nFor the music, we need to think of it as two parts: the intro and the bouncy loop. We can do this quite nicely with audio sprites: using one HTML5 audio element and using JavaScript to change the play head location, like skipping tracks with a CD player. Although this technique will result in a small gap in music shifts, I think it\u2019s worth using here to give you some ideas.\n\n// Get the audio element\nvar byakkoya = document.querySelector('audio');\n// create function to play and loop audio\nfunction song(a){\n    //start playing at 0\n    a.currentTime = 0;\n    a.play();\n    //when we hit 64 seconds...\n    setTimeout(function(){\n        // skip back to 24.5 seconds and keep playing...\n        a.currentTime = 24.55;\n        // then loop back when we hit 64 again, or every 59.5 seconds.\n        setInterval(function(){\n            a.currentTime = 24.55;\n        },39450);\n    },64000);\n}\n\nThe load screen\n\nI\u2019ve put it off as long as I can, but now that the music and the CSS are both running on their own separate clocks, it\u2019s imperative that both images and music be fully downloaded and ready to run when we kick this thing off. So we need a load screen (also, it\u2019s nice to give people a heads-up that you\u2019re about to blast them with music, no matter how wonderful that music may be).\n\nSince the two timers are so closely linked, we\u2019d best not run the animations until we run the music:\n\n* { animation-play-state: paused; }\n\nanimation-play-state can be set to paused or running, and it\u2019s the most useful thing you will learn today.\n\nFirst we use an event listener to see when the browser thinks we can play through from the beginning to end of the music without pause for buffering:\n\nbyakkoya.addEventListener(\"canplaythrough\", function () { });\n\n(More on HTML5 audio\u2019s media events at HTML5doctor.com)\n\nInside our event listener, I use a bit of jQuery to add class of .playable to the body when we\u2019re ready to enable the play button:\n\n$(\"body\").addClass(\"playable\");\n    $(\"#play-me\").html(\"Play me.\").click(function(){\n      song(byakkoya);\n      $(\"body\").addClass(\"playing\");\n    });\n\nThat .playing class is special because it turns on the animations at the same time we start playing the song:\n\n.playing * { animation-play-state: running; }\n\nThe background\n\nWe\u2019re almost done here! When we add the background, it needs to speed up at the same time that Tuna starts running. The music picks up speed around 24.75 seconds in, and so we\u2019re going to use animation-delay on those backgrounds, too.\n\nThis will require some math. If you try to simply shorten the animation\u2019s duration at the 24.75s mark, the backgrounds will, mid-scroll, jump back to their initial background positions to start the new animation! Argh! So let\u2019s make a new @keyframe and calculate where the background position would be just before we speed up the animation.\n\nHere\u2019s the formula:\n\nnew 0% value = delay \u00f7 old duration \u00d7 length of image\n\nnew 100% value = new 0% value + length of image\n\nHere\u2019s the formula put to work on a smaller scale:\n\n\n\nVoil\u00e0! The finished animation!\n\n\n\nI\u2019ve always wanted to bring my illustrations to life. Then I woke up one morning and realized that I had all the tools to do so in my browser and in my head. Now I have fallen in love with Flashless animation.\n\nI\u2019m sure there will be detractors who say HTML wasn\u2019t meant for this and it\u2019s a gross abuse of the DOM! But I say that these explorations help us expand what we expect from devices and software and challenge us in good ways as artists and programmers. The browser might not be the most appropriate place for animation, but is certainly a fun place to start.\n\nThere is so much you can do with the spec implemented today, and so much of the territory is still unexplored. I have not yet begun to show you everything. In eight months I expect this demo will represent the norm, not the bleeding edge. I look forward to seeing the wonderful things you create.\n\n(Also, someone, please, do something about that gappy HTML5 audio looping. It\u2019s a crying shame!)", "year": "2012", "author": "Rachel Nabors", "author_slug": "rachelnabors", "published": "2012-12-06T00:00:00+00:00", "url": "https://24ways.org/2012/flashless-animation/", "topic": "code"}
{"rowid": 95, "title": "Giving Content Priority with CSS3 Grid Layout", "contents": "Browser support for many of the modules that are part of CSS3 have enabled us to use CSS for many of the things we used to have to use images for. The rise of mobile browsers and the concept of responsive web design has given us a whole new way of looking at design for the web. However, when it comes to layout, we haven\u2019t moved very far at all. We have talked for years about separating our content and source order from the presentation of that content, yet most of us have had to make decisions on source order in order to get a certain visual layout. \n\nOwing to some interesting specifications making their way through the W3C process at the moment, though, there is hope of change on the horizon. In this article I\u2019m going to look at one CSS module, the CSS3 grid layout module, that enables us to define a grid and place elements on to it. This article comprises a practical demonstration of the basics of grid layout, and also a discussion of one way in which we can start thinking of content in a more adaptive way.\n\nBefore we get started, it is important to note that, at the time of writing, these examples work only in Internet Explorer 10. CSS3 grid layout is a module created by Microsoft, and implemented using the -ms prefix in IE10. My examples will all use the -ms prefix, and not include other prefixes simply because this is such an early stage specification, and by the time there are implementations in other browsers there may be inconsistencies. The implementation I describe today may well change, but is also there for your feedback.\n\nIf you don\u2019t have access to IE10, then one way to view and test these examples is by signing up for an account with Browserstack \u2013 the free trial would give you time to have a look. I have also included screenshots of all relevant stages in creating the examples.\n\nWhat is CSS3 grid layout?\n\nCSS3 grid layout aims to let developers divide up a design into a grid and place content on to that grid. Rather than trying to fabricate a grid from floats, you can declare an actual grid on a container element and then use that to position the elements inside. Most importantly, the source order of those elements does not matter. \n\nDeclaring a grid\n\nWe declare a grid using a new value for the display property: display: grid. As we are using the IE10 implementation here, we need to prefix that value: display: -ms-grid;.\n\nOnce we have declared our grid, we set up the columns and rows using the grid-columns and grid-rows properties.\n\n.wrapper {\n    display: -ms-grid;\n    -ms-grid-columns: 200px 20px auto 20px 200px;\n    -ms-grid-rows: auto 1fr;\n}\n\nIn the above example, I have declared a grid on the .wrapper element. I have used the grid-columns property to create a grid with a 200 pixel-wide column, a 20 pixel gutter, a flexible width auto column that will stretch to fill the available space, another 20 pixel-wide gutter and a final 200 pixel sidebar: a flexible width layout with two fixed width sidebars. Using the grid-rows property I have created two rows: the first is set to auto so it will stretch to fill whatever I put into it; the second row is set to 1fr, a new value used in grids that means one fraction unit. In this case, one fraction unit of the available space, effectively whatever space is left.\n\nPositioning items on the grid\n\nNow I have a simple grid, I can pop items on to it. If I have a <div> with a class of .main that I want to place into the second row, and the flexible column set to auto I would use the following CSS:\n\n.content {\n    -ms-grid-column: 3;\n    -ms-grid-row: 2;\n    -ms-grid-row-span: 1;\n}\n\nIf you are old-school, you may already have realised that we are essentially creating an HTML table-like layout structure using CSS. I found the concept of a table the most helpful way to think about the grid layout module when trying to work out how to place elements.\n\nCreating grid systems\n\nAs soon as I started to play with CSS3 grid layout, I wanted to see if I could use it to replicate a flexible grid system like this fluid 16-column 960 grid system.\n\nI started out by defining a grid on my wrapper element, using fractions to make this grid fluid.\n\n.wrapper {\t \n    width: 90%;\n    margin: 0 auto 0 auto;\n    display: -ms-grid;\n    -ms-grid-columns: 1fr (4.25fr 1fr)[16];\n    -ms-grid-rows: (auto 20px)[24];\n}\n\nLike the 960 grid system I was using as an example, my grid starts with a gutter, followed by the first actual column, plus another gutter repeated sixteen times. What this means is that if I want to span two columns, as far as the grid layout module is concerned that is actually three columns: two wide columns, plus one gutter. So this needs to be accounted for when positioning items.\n\nI created a CSS class for each positioning option: column position; rows position; and column span. For example:\n\n.grid1 {-ms-grid-column: 2;} /* applying this class positions an item in the first column (the gutter is column 1) */\n.grid2 {-ms-grid-column: 4;} /* 2nd column - gutter|column 1|gutter */\n.grid3 {-ms-grid-column: 6;} /* 3rd column - gutter|column 1|gutter|column2|gutter */\n\n.row1 {-ms-grid-row:1;}\n.row2 {-ms-grid-row:3;}\n.row3 {-ms-grid-row:5;}\n\n.colspan1 {-ms-grid-column-span:1;}\n.colspan2 {-ms-grid-column-span:3;}\n.colspan3 {-ms-grid-column-span:5;}\n\nI could then add multiple classes to each element to set the position on on the grid.\n\n\n\nThis then gives me a replica of the fluid grid using CSS3 grid layout. To see this working fire up IE10 and view Example 1.\n\nThis works, but\u2026\n\nThis worked, but isn\u2019t ideal. I considered not showing this stage of my experiment \u2013 however, I think it clearly shows how the grid layout module works and is a useful starting point. That said, it\u2019s not an approach I would take in production. First, we have to add classes to our markup that tie an element to a position on the grid. This might not be too much of a problem if we are always going to maintain the sixteen-column grid, though, as I will show you that the real power of the grid layout module appears once you start to redefine the grid, using different grids based on media queries. If you drop to a six-column layout for small screens, positioning items into column 16 makes no sense any more.\n\nCalculating grid position using LESS\n\nAs we\u2019ve seen, if you want to use a grid with main columns and gutters, you have to take into account the spacing between columns as well as the actual columns. This means we have to do some calculating every time we place an item on the grid. In my example above I got around this by creating a CSS class for each position, allowing me to think in sixteen rather than thirty-two columns. But by using a CSS preprocessor, I can avoid using all the classes yet still think in main columns.\n\nI\u2019m using LESS for my example. My simple grid framework consists of one simple mixin.\n\n.position(@column,@row,@colspan,@rowspan) {\n    -ms-grid-column: @column*2;\n    -ms-grid-row: @row*2-1;\n    -ms-grid-column-span: @colspan*2-1;\n    -ms-grid-row-span: @rowspan*2-1;\n}\n\nMy mixin takes four parameters: column; row; colspan; and rowspan. So if I wanted to place an item on column four, row three, spanning two columns and one row, I would write the following CSS:\n\n.box {\n    .position(4,3,2,1);\n}\n\nThe mixin would return:\n\n.box {\n    -ms-grid-column: 8;\n    -ms-grid-row: 5;\n    -ms-grid-column-span: 3;\n    -ms-grid-row-span: 1;\n}\n\nThis saves me some typing and some maths. I could also add other prefixed values into my mixin as other browsers started to add support.\n\nWe can see this in action creating a new grid. Instead of adding multiple classes to each element, I can add one class; that class uses the mixin to create the position. I have also played around with row spans using my mixin and you can see we end up with a quite complicated arrangement of boxes. Have a look at example two in IE10. I\u2019ve used the JavaScript LESS parser so that you can view the actual LESS that I use. Note that I have needed to escape the -ms prefixed properties with ~\"\" to get LESS to accept them.\n\n\n\nThis is looking better. I don\u2019t have direct positioning information on each element in the markup, just a class name \u2013 I\u2019ve used grid(x), but it could be something far more semantic. We can now take the example a step further and redefine the grid based on screen width.\n\nMedia queries and the grid\n\nThis example uses exactly the same markup as the previous example. However, we are now using media queries to detect screen width and redefine the grid using a different number of columns depending on that width.\n\nI start out with a six-column grid, defining that on .wrapper, then setting where the different items sit on this grid:\n\n.wrapper {\t \n    width: 90%;\n    margin: 0 auto 0 auto;\n    display: ~\"-ms-grid\"; /* escaped for the LESS parser */\n    -ms-grid-columns: ~\"1fr (4.25fr 1fr)[6]\"; /* escaped for the LESS parser */\n    -ms-grid-rows: ~\"(auto 20px)[40]\"; /* escaped for the LESS parser */\n}\n.grid1 { .position(1,1,1,1); } \n.grid2 { .position(2,1,1,1); } \n/* ... see example for all declarations ... */\n\n\n\nUsing media queries, I redefine the grid to nine columns when we hit a minimum width of 700 pixels.\n\n@media only screen and (min-width: 700px) {\n.wrapper {\n    -ms-grid-columns: ~\"1fr (4.25fr 1fr)[9]\";\n    -ms-grid-rows: ~\"(auto 20px)[50]\";\n}\n.grid1 { .position(1,1,1,1); } \n.grid2 { .position(2,1,1,1); } \n/* ... */\n}\n\n\n\nFinally, we redefine the grid for 960 pixels, back to the sixteen-column grid we started out with.\n\n@media only screen and (min-width:  940px) {\n.wrapper {\t \n    -ms-grid-columns:~\" 1fr (4.25fr 1fr)[16]\";\n    -ms-grid-rows:~\" (auto 20px)[24]\";\n}\n.grid1 { .position(1,1,1,1); } \n.grid2 { .position(2,1,1,1); } \n/* ... */\n}\n\nIf you view example three in Internet Explorer 10 you can see how the items reflow to fit the window size. You can also see, looking at the final set of blocks, that source order doesn\u2019t matter. You can pick up a block from anywhere and place it in any position on the grid.\n\nLaying out a simple website\n\nSo far, like a toddler on Christmas Day, we\u2019ve been playing with boxes rather than thinking about what might be in them. So let\u2019s take a quick look at a more realistic layout, in order to see why the CSS3 grid layout module can be really useful. At this time of year, I am very excited to get out of storage my collection of odd nativity sets, prompting my family to suggest I might want to open a museum. Should I ever do so, I\u2019ll need a website, and here is an example layout.\n\n\n\nAs I am using CSS3 grid layout, I can order my source in a logical manner. In this example my document is as follows, though these elements could be in any order I please:\n\n<div class=\"wrapper\">\n  <div class=\"welcome\">\n  ...\n  </div>\n  <article class=\"main\">\n  ...\n  </article>\n  <div class=\"info\">\n  ...\n  </div>\n  <div class=\"ads\">\n  ...\n  </div>\n</div>\n\nFor wide viewports I can use grid layout to create a sidebar, with the important information about opening times on the top righ,t with the ads displayed below it. This creates the layout shown in the screenshot above.\n\n@media only screen and (min-width:  940px) {\n  .wrapper {\t \n    -ms-grid-columns:~\" 1fr (4.25fr 1fr)[16]\";\n    -ms-grid-rows:~\" (auto 20px)[24]\";\n  }\n  .welcome {\n    .position(1,1,12,1);\n    padding: 0 5% 0 0;\n  }\n  .info {\n    .position(13,1,4,1);\n    border: 0;\n    padding:0;\n   }\n  .main {\n    .position(1,2,12,1);\n    padding: 0 5% 0 0;\n  }  \n  .ads {\n    .position(13,2,4,1);\n    display: block;\n    margin-left: 0;\n  }\n}\n\nIn a floated layout, a sidebar like this often ends up being placed under the main content at smaller screen widths. For my situation this is less than ideal. I want the important information about opening times to end up above the main article, and to push the ads below it. With grid layout I can easily achieve this at the smallest width .info ends up in row two and .ads in row five with the article between.\n\n.wrapper {\t \n  display: ~\"-ms-grid\";\n  -ms-grid-columns: ~\"1fr (4.25fr 1fr)[4]\";\n  -ms-grid-rows: ~\"(auto 20px)[40]\";\n}\n.welcome {\n    .position(1,1,4,1);\n}\n.info {\n    .position(1,2,4,1);\n    border: 4px solid #fff;\n    padding: 10px;\n}\n.content {\n    .position(1,3,4,5);\n}\n.main {\n    .position(1,3,4,1);\n}\n.ads {\n    .position(1,4,4,1);\n}\n\n\n\nFinally, as an extra tweak I add in a breakpoint at 600 pixels and nest a second grid on the ads area, arranging those three images into a row when they sit below the article at a screen width wider than the very narrow mobile width but still too narrow to support a sidebar. \n\n@media only screen and (min-width:  600px) {\n  .ads {\n    display: ~\"-ms-grid\";\n    -ms-grid-columns: ~\"20px 1fr 20px 1fr 20px 1fr\";\n    -ms-grid-rows: ~\"1fr\";\n    margin-left: -20px;\n  }\n  .ad:nth-child(1) {\n    .position(1,1,1,1);\n  }\n  .ad:nth-child(2) {\n    .position(2,1,1,1);\n  }\n  .ad:nth-child(3) {\n    .position(3,1,1,1);\n  }\n}\n\nView example four in Internet Explorer 10.\n\n\n\nThis is a very simple example to show how we can use CSS grid layout without needing to add a lot of classes to our document. It also demonstrates how we can mainpulate the content depending on the context in which the user is viewing it.\n\nLayout, source order and the idea of content priority\n\nCSS3 grid layout isn\u2019t the only module that starts to move us away from the issue of visual layout being linked to source order. However, with good support in Internet Explorer 10, it is a nice way to start looking at how this might work. If you look at the grid layout module as something to be used in conjunction with the flexible box layout module and the very interesting CSS regions and exclusions specifications, we have, tantalizingly on the horizon, a powerful set of tools for layout.\n\nI am particularly keen on the potential separation of source order from layout as it dovetails rather neatly into something I spend a lot of time thinking about. As a CMS developer, working on larger scale projects as well as our CMS product Perch, I am interested in how we better enable content editors to create content for the web. In particular, I search for better ways to help them create adaptive content; content that will work in a variety of contexts rather than being tied to one representation of that content.\n\nIf the concept of adaptive content is new to you, then Karen McGrane\u2019s presentation Adapting Ourselves to Adaptive Content is the place to start. Karen talks about needing to think of content as chunks, that might be used in many different places, displayed differently depending on context.\n\nI absolutely agree with Karen\u2019s approach to content. We have always attempted to move content editors away from thinking about creating a page and previewing it on the desktop. However at some point content does need to be published as a page, or a collection of content if you prefer, and bits of that content have priority. Particularly in a small screen context, content gets linearized, we can only show so much at a time, and we need to make sure important content rises to the top. In the case of my example, I wanted to ensure that the address information was clearly visible without scrolling around too much. Dropping it with the entire sidebar to the bottom of the page would not have been so helpful, though neither would moving the whole sidebar to the top of the screen so a visitor had to scroll past advertising to get to the article.\n\nIf our layout is linked to our source order, then enabling the content editor to make decisions about priority is really hard. Only a system that can do some regeneration of the source order on the server-side \u2013 perhaps by way of multiple templates \u2013 can allow those kinds of decisions to be made. For larger systems this might be a possibility; for smaller ones, or when using an off-the-shelf CMS, it is less likely to be. Fortunately, any system that allows some form of custom field type can be used to pop a class on to an element, and with CSS grid layout that is all that is needed to be able to target that element and drop it into the right place when the content is viewed, be that on a desktop or a mobile device.\n\nThis approach can move us away from forcing editors to think visually. At the moment, I might have to explain to an editor that if a certain piece of content needs to come first when viewed on a mobile device, it needs to be placed in the sidebar area, tying it to a particular layout and design. I have to do this because we have to enforce fairly strict rules around source order to make the mechanics of the responsive design work. If I can instead advise an editor to flag important content as high priority in the CMS, then I can make decisions elsewhere as to how that is displayed, and we can maintain the visual hierarchy across all the different ways content might be rendered.\n\nWhy frustrate ourselves with specifications we can\u2019t yet use in production?\n\nThe CSS3 grid layout specification is listed under the Exploring section of the list of current work of the CSS Working Group. While discussing a module at this stage might seem a bit pointless if we can\u2019t use it in production work, there is a very real reason for doing so. If those of us who will ultimately be developing sites with these tools find out about them early enough, then we can start to give our feedback to the people responsible for the specification. There is information on the same page about how to get involved with the disussions.\n\nSo, if you have a bit of time this holiday season, why not have a play with the CSS3 grid layout module? I have outlined here some of my thoughts on how grid layout and other modules that separate layout from source order can be used in the work that I do. Likewise, wherever in the stack you work, playing with and thinking about new specifications means you can think about how you would use them to enhance your work. Spot a problem? Think that a change to the specification would improve things for a specific use case? Then you have something you could post to www-style to add to the discussion around this module.\n\nAll the examples are on CodePen so feel free to play around and fork them.", "year": "2012", "author": "Rachel Andrew", "author_slug": "rachelandrew", "published": "2012-12-18T00:00:00+00:00", "url": "https://24ways.org/2012/css3-grid-layout/", "topic": "code"}
{"rowid": 76, "title": "Giving CSS Animations and Transitions Their Place", "contents": "CSS animations and transitions may not sit squarely in the realm of the behaviour layer, but they\u2019re stepping up into this area that used to be pure JavaScript territory. Heck, CSS might even perform better than its JavaScript equivalents in some cases. That\u2019s pretty serious! With CSS\u2019s new tricks blurring the lines between presentation and behaviour, it can start to feel bloated and messy in our CSS files. It\u2019s an uncomfortable feeling.\n\nHere are a pair of methods I\u2019ve found to be pretty helpful in keeping the potential bloat and wire-crossing under control when CSS has its hands in both presentation and behaviour.\n\nSame eggs, more baskets\n\nStructuring your CSS to have separate files for layout, typography, grids, and so on is a fairly common approach these days. But which one do you put your transitions and animations in? The initial answer, as always, is \u201cit depends\u201d.\n\nSmall effects here and there will likely sit just fine with your other styles. When you move into more involved effects that require multiple animations and some logic support from JavaScript, it\u2019s probably time to choose none of the above, and create a separate CSS file just for them.\n\nPutting all your animations in one file is a huge help for code organization. Even if you opt for a name less literal than animations.css, you\u2019ll know exactly where to go for anything CSS animation related. That saves time and effort when it comes to editing and maintenance. Keeping track of which animations are still currently used is easier when they\u2019re all grouped together as well. And as an added bonus, you won\u2019t have to look at all those horribly unattractive and repetitive prefixed @-keyframe rules unless you actually need to.\n\nAn animations.css file might look something like the snippet below. It defines each animation\u2019s keyframes and defines a class for each variation of that animation you\u2019ll be using. Depending on the situation, you may also want to include transitions here in a similar way. (I\u2019ve found defining transitions as their own class, or mixin, to be a huge help in past projects for me.)\n\n// defining the animation\n@keyframes catFall {\n from { background-position: center 0;}\n to {background-position: center 1000px;}\n}\n@-webkit-keyframes catFall {\n from { background-position: center 0;}\n to {background-position: center 1000px;}\n}\n@-moz-keyframes catFall {\n from { background-position: center 0;}\n to {background-position: center 1000px;}\n}\n@-ms-keyframes catFall {\n from { background-position: center 0;}\n to {background-position: center 1000px;}\n}\n\n\u2026\n\n// class that assigns the animation\n\n.catsBackground {\n height: 100%;\n background: transparent url(../endlessKittens.png) 0 0 repeat-y;\n animation: catFall 1s linear infinite;\n -webkit-animation: catFall 1s linear infinite;\n -moz-animation: catFall 1s linear infinite;\n -ms-animation: catFall 1s linear infinite;\n}\n\nIf we don\u2019t need it, why load it?\n\nHaving all those CSS animations and transitions in one file gives us the added flexibility to load them only when we want to. Loading a whole lot of things that will never be used might seem like a bit of a waste.\n\nWhile CSS has us impressed with its motion chops, it falls flat when it comes to the logic and fine-grained control. JavaScript, on the other hand, is pretty good at both those things. Chances are the content of your animations.css file isn\u2019t acting alone. You\u2019ll likely be adding and removing classes via JavaScript to manage your CSS animations at the very least. If your CSS animations are so entwined with JavaScript, why not let them hang out with the rest of the behaviour layer and only come out to play when JavaScript is supported?\n\nDynamically linking your animations.css file like this means it will be completely ignored if JavaScript is off or not supported. No JavaScript? No additional behaviour, not even the parts handled by CSS.\n\n<script>\ndocument.write('<link rel=\"stylesheet\" type=\"text/css\" href=\"animations.css\">');\n</script>\n\nThis technique comes up in progressive enhancement techniques as well, but it can help here to keep your presentation and behaviour nicely separated when more than one language is involved. The aim in both cases is to avoid loading files we won\u2019t be using.\n\nIf you happen to be doing something a bit fancier \u2013 like 3-D transforms or critical animations that require more nuanced fallbacks \u2013 you might need something like modernizr to step in to determine support more specifically. But the general idea is the same.\n\nSumming it all up\n\nUsing a couple of simple techniques like these, we get to pick where to best draw the line between behaviour and presentation based on the situation at hand, not just on what language we\u2019re using. The power of when to separate and how to reassemble the individual pieces can be even greater if you use preprocessors as part of your process. We\u2019ve got a lot of options!

{"rowid": 75, "title": "A Harder-Working Class", "contents": "Class is only becoming more important. Focusing on its original definition as an attribute for grouping (or classifying) as well as linking HTML to CSS, recent front-end development practices are emphasizing class as a vessel for structured, modularized style packages. These patterns reduce the need for repetitive declarations that can seriously bloat file sizes, and instil human-readable understanding of how the interface, layout, and aesthetics are constructed.\n\nIn the next handful of paragraphs, we will look at how these emerging practices \u2013 such as object-oriented CSS and SMACSS \u2013 are pushing the relevance of class. We will also explore how HTML and CSS architecture can be further simplified, performance can be boosted, and CSS utility sharpened by combining class with the attribute selector.\n\nA primer on attribute selectors\n\nWhile attribute selectors were introduced in the CSS 2 spec, they are still considered rather exotic. These well-established and well-supported features give us vastly improved flexibility in targeting elements in CSS, and offer us opportunities for smarter markup. With an attribute selector, you can directly style an element based on any of its unique \u2013 or uniquely shared \u2013 attributes, without the need for an ID or extra classes. Unlike pseudo-classes, pseudo-elements, and other exciting features of CSS3, attribute selectors do not require any browser-specific syntax or prefix, and are even supported in Internet Explorer 7. \n\nFor example, say we want to target all anchor tags on a page that link to our homepage. Where otherwise we might need to manually identify and add classes to the HTML for these specific links, we could simply write:\n\n[href=index.html] {  }\n\nThis selector reads: target every element that has an href attribute of \u201cindex.html\u201d. \n\nAttribute selectors are more faceted, though, as they also give us some very simple regular expression-like logic that helps further narrow (or widen) a selector\u2019s scope. In our previous example, what if we wanted to also give indicative styles to any anchor tag linking to an external site? With no way to know what the exact href value would be for every external link, we need to use an expression to match a common aspect of those links. In this case, we know that all external links need to start with \u201chttp\u201d, so we can use that as a hook:\n\n[href^=http] {  }\n\nThe selector here reads: target every element that has an href attribute that begins with \u201chttp\u201d (which will also include \u201chttps\u201d). The ^= means \u201cstarts with\u201d. There are a few other simple expressions that give us a lot of flexibility in targeting elements, and I have found that a deep understanding of these and other selector types to be very useful.\n\nThe class-attribute selector\n\nBy matching classes with the attribute selector, CSS can be pushed to accomplish some exciting new feats. What I call a class-attribute selector combines the advantages of classes with attribute selectors by targeting the class attribute, rather than a specific class. Instead of selecting .urgent, you could select [class*=urgent]. The latter may seem like a more verbose way of accomplishing the former, but each would actually match two subtly different groups of elements.\n\nEric Meyer first explored the possibility of using classes with attribute selectors over a decade ago. While his interest in this technique mostly explored the different facets of the syntax, I have found that using class-attribute selectors can have distinct advantages over either using an attribute selector or a straightforward class selector.\n\nFirst, let\u2019s explore some of the subtleties of why we would target class before other attributes:\n\n\n\tClasses are ubiquitous. They have been supported since the HTML 4 spec was released in 1999. Newer attributes, such as the custom data attribute, have only recently begun to be adopted by browsers.\n\tClasses have multiple ways of being targeted. You can use the class selector or attribute selector (.classname or [class=classname]), allowing more flexible specificity than resorting to an ID or !important.\n\tClasses are already widely used, so adding more classes will usually require less markup than adding more attributes.\n\tClasses were designed to abstractly group and specify elements, making them the most appropriate attribute for styling using object-oriented methods (as we will learn in a moment).\n\n\nAlso, as Meyer pointed out, we can use the class-attribute selector to be more strict about class declarations. Of these two elements:\n\n<h2 class=\"very urgent\">\n\n<h2 class=\"urgent\">\n\n\u2026only the second h2 would be selected by [class=urgent], while .urgent would select both. The use of = matches any element with the exact class value of \u201curgent\u201d. Eric explores these nuances further in his series on attribute selectors, but perhaps more dramatic is the added power that class-attribute selectors can bring to our CSS.\n\nMore object-oriented, more scalable and modular\n\nNicole Sullivan has been pushing abstracted, object-oriented thinking in CSS development for years now. She has shared stacks of knowledge on how behemoth sites have seen impressive gains in maintenance overhead and CSS file sizes by leaning heavier on classes derived from common patterns. Jonathan Snook also speaks, writes and is genuinely passionate about improving our markup by using more stratified and modular class name conventions. With SMACSS, he shows this to be highly useful across sites \u2013 both complex and simple \u2013 that exhibit repeated design patterns. Sullivan and Snook both push the use of class for styling over other attributes, and many front-end developers are fast advocating such thinking as best practice.\n\nWith class-attribute selectors, we can further abstract our CSS, pushing its scalability. In his chapter on modules, Snook gives the example of a .pod class that might represent a certain set of styles. A .pod style set might be used in varying contexts, leading to CSS that might normally look like this:\n\n.pod {  }\nform .pod {  }\naside .pod {  }\n\nAccording to Snook, we can make these styles more portable by targeting more verbose classes, rather than context:\n\n.pod {  }\n.pod-form {  }\n.pod-sidebar {  }\n\n\u2026resulting in the following HTML:\n\n<div class=\"pod\">\n<div class=\"pod pod-form\">\n<div class=\"pod pod-sidebar\">\n\nThis divorces the <div>\u2019s styles from its context, making it applicable to any situation in which it is needed. The markup is clean and portable, and the classes are imbued with meaning as to what module they belong to. \n\nUsing class-attribute selectors, we can simplify this further:\n\n[class*=pod] {  }\n.pod-form {  }\n.pod-sidebar {  }\n\nThe *= tells the browser to look for any element with a class attribute containing \u201cpod\u201d, so it matches \u201cpod\u201d, \u201cpod-form\u201d, \u201cpod-sidebar\u201d, etc. This allows only one class per element, resulting in simpler HTML:\n\n<div class=\"pod\">\n<div class=\"pod-form\">\n<div class=\"pod-sidebar\">\n\nWe could further abstract the concept of \u201cform\u201d and \u201csidebar\u201d adjustments if we knew that each of those alterations would always need the same treatment.\n\n/* Modules */\n[class*=pod] {  }\n[class*=btn] {  }\n\n/* Alterations */\n[class*=-form] {  }\n[class*=-sidebar] {  }\n\nIn this case, all elements with classes appended \u201c-form\u201d or \u201c-sidebar\u201d would be altered in the same manner, allowing the markup to stay simple:\n\n<form>\n  <h2 class=\"pod-form\">\n  <a class=\"btn-form\" href=\"#\">\n\n<aside>\n  <h2 class=\"pod-sidebar\">\n  <a class=\"btn-sidebar\" href=\"#\">\n\n50+ shades of specificity\n\nClasses are just powerful enough to override element selectors and default styling, but still leave room to be trumped by IDs and !important styles. This makes them more suitable for object-oriented patterns and helps avoid messy specificity issues that can not only be a pain for developers to maintain, but can also affect a site\u2019s performance. As Sullivan notes, \u201cIn almost every case, classes work well and have fewer unintended consequences than either IDs or element selectors\u201d. Proper use of specificity and cascade is crucial in building straightforward, efficient CSS.\n\nOne interesting aspect of attribute selectors is that they can be compounded for increasing levels of specificity. Attribute selectors are assigned a specificity level of ten, the same as class selectors, but both class and attribute selectors can be chained together, giving them more and more specificity with each link. Some examples:\n\n.box {  } \n/* Specificity of 10 */\n\n.box.promo {  } \n/* Specificity of 20 */\n\n[class*=box] {  } \n/* Specificity of 10 */\n\n[class*=box][class*=promo] {  } \n/* Specificity of 20 */\n\nYou can chain both types together, too:\n\n.box[class*=promo] {  } \n/* Specificity of 20 */\n\nI was amused to find, though, that you can chain the exact same class and attribute selectors for infinite levels of specificity\n\n.box {  } \n/* Specificity of 10 */\n\n.box.box {  } \n/* Specificity of 20 */\n\n.box.box.box {  } \n/* Specificity of 30 */\n\n[class*=box] {  }\n/* Specificity of 10 */\n\n[class*=box][class*=box] {  }\n/* Specificity of 20 */\n\n[class*=box][class*=box][class*=box] {  }\n/* Specificity of 30 */\n\n.box[class*=box].box[class*=box] {  } \n/* Specificity of 40 */\n\nTo override .box styles for promo, we wouldn\u2019t need to add an ID, change the order of .promo and .box in the CSS, or resort to an !important style. Granted, any issue that might need this fine level of specificity tweaking could probably be better solved with clever cascades, but having options never hurts.\n\nSmarter CSS\n\nOne of the most powerful aspects of the class-attribute selector is its ability to expand the simple logic found in CSS. When developing Gridset (an online tool for building grids and outputting them as CSS), I realized that with the right class name conventions, class-attribute selectors would allow the CSS to be smart enough to automatically adjust for column offsets without the need for extra classes. This imbued the CSS output with logic that other frameworks lacked, and makes a developer\u2019s job much easier. \n\nSay you need an element that spans column five (c5) to column six (c6) on your grid, and is preceded by an element spanning column one (c1) to column three (c3). The CSS can anticipate such a scenario:\n\n.c1-c3 + .c5-c6 {\n  margin-left: 25%; /* \u2026or the width of column four plus two gutter widths */\n}\n\n\u2026but to accommodate all of the margin offsets that could span that same gap, we would need to write a rather protracted list for just a six column grid:\n\n.c1-c3 + .c5-c6,\n.c1-c3 + .c5,\n.c2-c3 + .c5-c6,\n.c2-c3 + .c5,\n.c3 + .c5-c6,\n.c3 + .c5 {\n  margin-left: 25%; \n}\n\nNow imagine how the verbosity compounds when we repeat this type of declaration for every possible margin in a grid. The more columns added to the grid, the longer this selector list would get, too, making the CSS harder for the developer to maintain and slowing the load time. Using class-attribute selectors, though, this can be much simpler:\n\n[class*=c3] + [class*=c5] {\n  margin-left: 25%;\n}\n\nI\u2019ve detailed how we extract as much logic as possible from as little CSS as needed on the Gridset blog.\n\nMore flexible selectors\n\nIn a recent project, I was working with Drupal-generated classes to change styles for certain special pages on a site. Without being able to change the code base, I was left trying to find some specific aspect of the generated HTML to target. I noticed that every special page was given a prefixed class, unique to the page, resulting in CSS like this:\n\n.specialpage-about,\n.specialpage-contact,\n.specialpage-info,\n\u2026\n\n\u2026and the list kept growing with each new special page. Such bloat would lead to problems down the line, and add development overhead to editorial decisions, which was a situation we were trying to avoid. I was easily able to fix this, though, with a concise class-attribute selector:\n\n[class*=specialpage-]\n\nThe CSS was now flexible enough to accommodate both the editorial needs of the client, and the development restrictions of the CMS.\n\nSelector performance\n\nAs Snook tells us in his chapter on Selector Performance, selectors are read by the browser from right to left, matching every element that adheres to each rule (or part of the selector). The more specific we can make the right-most rules \u2013 and every other part of your selectors \u2013 the more performant your CSS will be. So this selector:\n\n.home-page .promo .main-header\n\n\u2026would be more performant than:\n\n.home-page div header\n\n\u2026because there are likely many more header and div elements on the page, but not so many elements with those specific classes.\n\nNow, the class-attribute selector could be more general than a class selector, but not by much. I ran numerous tests based on the work of Steve Souders (and a few others) to test a class-attribute selector against a normal class selector. Given that Javascript will freeze during style rendering, I created a script that will add, then remove, a stylesheet on a page 5000 times, and measure only the time that elapses during the rendering freeze. The script runs four tests, essentially: one where a class selector and class-attribute Selector match a single element, and one they match multiple elements on the page.\n\nAfter running the test over 100 times and averaging the results, I have not seen a significant difference in rendering times. (As of this writing, the class-attribute selector has been 0.398% slower on average.) View the results here.\n\nGiven the sheer amount of bytes potentially saved by reducing selector lists, though, I am confident class-attribute selectors could shorten load times on larger sites and, at the very least, save precious development time.\n\nConclusion\n\nWith its flexibility and broad remit, class has at times been derided as too lenient, allowing CMSes and lazy developers to fill its values with presentational hacks or verbose gibberish. There have even been calls for an early retirement. Class continues, though, to be one of our most crucial tools.\n\nFront-end developers are rightfully eager to expand production abilities through innovations such as Sass or LESS, but this should not preclude us from honing the tools we already know as well. Every technique demonstrated in this article was achievable over a decade ago and most of the same thinking could be applied to IDs, rels, or any other attribute (though the reasons listed above give class an edge). The recent advent of methods such as object-oriented CSS and SMACSS shows there is still much room left to expand what simple HTML and CSS can accomplish. Progress may not always be found in the innovation of our tools, but through sharpening our understanding of them.", "year": "2012", "author": "Nathan Ford", "author_slug": "nathanford", "published": "2012-12-15T00:00:00+00:00", "url": "https://24ways.org/2012/a-harder-working-class/", "topic": "code"}
{"rowid": 74, "title": "Should We Be Reactive?", "contents": "Evolution\n\nLooking at the evolution of the web and the devices we use should help remind us that the times we\u2019re adjusting to are just another step on a journey. These times seem to be telling us that we need to embrace flexibility.\n\nImagine an HTML file containing nothing but text. It\u2019s viewable on any web-capable device and reasonably readable: the notion of the universality of the web was very much a founding principle. Right from the beginning, browser vendors understood that we\u2019d want text to reflow (why wouldn\u2019t we?), so I consider the first websites to have been fluid. \n\nAs we attempted to exert more control through our designs in the early days of the web, debates about whether we should produce fixed or fluid sites raged. We could create fluid designs using tables, but what we didn\u2019t have then was a wide range of web capable devices or the ability to control this fluidity. The biggest changes occurred when stats showed enough people using a different screen resolution we could cater for.\n\nTo me, the techniques of responsive web design provide the control we were missing. Combining new approaches to layout and images with media queries empowered us to learn how to embrace the inherent flexibility of the web in ways to suit our work and the devices used by our audience.\n\nPerhaps another kind of flexibility might be found in how we use context to affect how we present our content; to consider how we might use the information we can access from people, browsers and devices to provide web experiences \u2013 effectively creating sites that react to initial or changing circumstances in the relationship between people and our content.\n\nEmbracing flexibility\n\nSo what is context? Put simply, you could think of it as a secondary piece of information that helps clarify the meaning of the first. It helps set a scene or describe circumstances. I think that Cennydd Bowles has summed it up really well through talks he\u2019s given recently, in which he\u2019s arrived at the acronym DETAILS (Device, Environment, Time, Activity, Individual, Location, Social) \u2013 I encourage you to keep an eye out for his next book due in the new year where he\u2019ll explore this idea much further. This clarity over what context could mean in terms of what we do on the web is fundamental, directing us towards ways we might use it.\n\nWhen you stop to think about it, we\u2019ve been using some basic pieces of this information right from the beginning, like bits of JavaScript or Java applets that serve an appropriate greeting to your site\u2019s visitors, or show their location, or even local weather. But what if we think of this from the beginning of our projects?\n\nWe should think about our content first. Once we know this and have a direction, perhaps then we can think about what context, or even multiple contexts, might help us to communicate more effectively.\n\nThe real world\n\nThere\u2019s always been a disconnect between the real world and the web, which is to be expected. But the world around us is a sea of data; every fundamental building block: people, places, events and things have information waiting to be explored. \n\nFor sites based around physical objects or locations, this divide is really apparent. We don\u2019t ordinarily take the time to describe in code the properties of a place, or consider whether your relationship to the place in the real world should have any impact on your relationship with a site about it.\n\nWhen I think about local businesses, they have such rich properties to draw on and yet we don\u2019t really explore them in any meaningful way, even through something as simple as opening hours.\n\nNow we have data\u2026\n\nWe\u2019ve long had access to the current time both on server- and client-sides. The use of geolocation is easier than ever, but when we look at the range of information we could glean to help us make some choices, maybe there\u2019s some help on the horizon from projects like the W3C Device APIs Working Group. This might prove useful to help make us aware of network and battery conditions of a device, along with the potential to gain data from other sensors, which could tell us about lighting conditions, ambient noise levels and temperature depending on the capabilities of the device.\n\nIt may be that our sites have some form of login or access to your profile from another site. Along with data from our devices and browsers, this should give us a sense of how best to talk to our audience in certain situations. We don\u2019t necessarily need to know any personal details, just enough to make decisions about how to present our sites.\n\nThe reactive web?\n\nSo why reactive web design? I\u2019m hoping that a name might help us to have a common vocabulary not only about what we mean when we talk about context, but how it could be considered through our projects, right from the early stages. How could this manifest itself?\n\nA simple example might be a location-aware panel on your site. Perhaps the space is a little down in your content hierarchy but serves a perfectly valid purpose by default. To visitors outside the country perhaps this works fine, but within your country maybe this panel could be used to communicate more effectively. Further still, if we knew the visitors were in the vicinity, we could talk to them more directly. \n\nWhat if both time and location were relevant? This space could work as before but you could consider how time could intersect with your local audience. If you know they\u2019re local and it\u2019s a certain time of day, you could communicate directly with them.\n\nThis example isn\u2019t beyond what banner ads often do and uses easily accessible information. There are more unusual combinations we may be able to find, such as movement and presence. Perhaps a site that tells a story, which changes design and content based on whether you\u2019re moving, how long you\u2019ve been on the site and how far you\u2019ve travelled. This isn\u2019t what we typically expect from websites, but we should bear in mind that what websites are now will not be what they become in the future.\n\nYou could do much of this contextual presentation through native apps, of course. The Silent History, an app novel written and designed for iPad and iPhone, uses an exploration element, providing \u201chundreds of location-based stories across the U.S. and around the world. These can be read only when your device\u2019s GPS matches the coordinates of the specified location.\u201d But considering the universality of the web, we could redefine what web-based experiences should be like. Not all methods would work well on the web, but that\u2019s a decision that has to be made for a specific project.\n\nBy thinking more broadly about any web-capable device, we can use what we know to provide relevant experiences for our site\u2019s visitors. We need to be sure what we mean by relevant, of course!\n\nReality bites\n\nWhile there are incredible possibilities, from a simple panel on a site to something bordering on living sites that evolve and change with our circumstances, we need to act with a degree of pragmatism and understand how much of what we could do is based on assumptions and the bias of our own experiences.\n\nWe could go wild with changing the way our content is presented based on contextual information, but if we\u2019re not careful what we end up with confuses and could provide a very fractured experience. As much as possible we need to think more ethnographically, observe and question people in the situations we think may be relevant, and test our assumptions as early as we can. Even on small projects, there may be ways we can validate our assumptions and test with our audience. The key to applying contextual content or cues is not to break the experience between contextual views (as I think we now wouldn\u2019t when hiding content on a mobile view). \n\nIt\u2019s another instance of progressive enhancement \u2013 as we know certain pieces of information, we can enhance the experience. Also, if you do change content, how can you not make a more cumbersome experience for your visitors?\n\nIt\u2019s all about communication\n\nContent is at the core of what we do, but if we consider context we need to understand the impact on that. The effect could be as subtle as an altered hierarchy, involve swapping out panels of content, or in extreme instances perhaps all of your content might change. In some ways, this extends the notion of adaptive content that Karen McGrane has been talking about, to how we write and store the content we create. Thinking about the the impact of context may require us to re-evaluate our site structure, too. Whatever we decide, we have to be clear what will happen and manage the expectations of our users.\n\nThe bottom line\n\nWhat I\u2019m proposing isn\u2019t that we go crazy and end up with a confused, disjointed set of experiences across the web. What I hope is that starting right from the beginning of a project, we think about what context is and could be, and see what relevance it might have to what we\u2019re trying to communicate. This strategic process leads us to think about design.\n\nWe are slowly adapting to what it means to be flexible through responsive and adaptive processes. What does thinking about contextual states mean to us (or designing for state in general)? Does this highlight again how difficult it\u2019ll be for our tools to keep up with our processes and output?\n\nIn terms of code, the vast majority of this data comes from the client-side through JavaScript. While we can progressively enhance, this could lead to a lot of code bloat through feature or capability detection, and potentially a lot of conditional loading of scripts. It\u2019s a real shame we don\u2019t get much we can rely on from the server-side \u2013 we know how unreliable user agents are!\n\nWe need to understand why we\u2019d do this. Are we trying to communicate well and be useful, or doing it to show off? Underneath it all, what do we base our decisions on? Do we have actual insight or are we proceeding from our assumptions and the bias of our own experiences? Scott Jenson summed it up best for me: (to paraphrase) the pain we put people through has to be greatly outweighed by the value we offer.\n\nI see that this could be another potential step in our evolution on the web; continuing this exploration of the flexibility the web allows us. It\u2019s amazing we can do such incredible things from what is essentially a set of disparate, linked documents.", "year": "2012", "author": "Dan Donald", "author_slug": "dandonald", "published": "2012-12-09T00:00:00+00:00", "url": "https://24ways.org/2012/should-we-be-reactive/", "topic": "design"}
{"rowid": 77, "title": "Colour Accessibility", "contents": "Here\u2019s a quote from Josef Albers:\n\nIn visual perception a colour is almost never seen as it really is[\u2026] This fact makes colour the most relative medium in art.Josef Albers, Interaction of Color, 1963\n\nAlbers was a German abstract painter and teacher, and published a very famous course on colour theory in 1963. Colour is very relative \u2014 not just in the way that it appears differently across different devices due to screen quality and colour management, but it can also be seen differently by different people \u2014 something we really need to be more mindful of when designing.\n\nWhat is colour blindness?\n\nColour blindness very rarely means that you can\u2019t see any colour at all, or that people see things in greyscale. It\u2019s actually a decreased ability to see colour, or a decreased ability to tell colours apart from one another. \n\nHow does it happen?\n\nInside the typical human retina, there are two types of receptor cells \u2014 rods and cones. Rods are the cells that allow us to see dark and light, and shape and movement. Cones are the cells that allow us to perceive colour. There are three types of cones, each responsible for absorbing blue, red, and green wavelengths in the spectrum.\n\nProblems with colour vision occur when one or more of these types of cones are defective or absent entirely, and these problems can either be inherited through genetics, or acquired through trauma, exposure to ultraviolet light, degeneration with age, an effect of diabetes, or other factors.\n\nColour blindness is a sex-linked trait and it\u2019s much more common in men than in women. The most common type of colour blindness is called deuteranomaly which occurs in 7% of males, but only 0.5% of females. That\u2019s a pretty significant portion of the population if you really stop and think about it \u2014\u00a0we can\u2019t ignore this demographic.\n\nWhat does it look like?\n\nPeople with the most common types of colour blindness, like protanopia and deuteranopia, have difficulty discriminating between red and green hues. There are also forms of colour blindness like tritanopia, which affects perception of blue and yellow hues. Below, you can see what a colour wheel might look like to these different people.\n\n\n\nWhat can we do?\n\nHere are some things you can do to make your websites and apps more accessible to people with all types of colour blindness.\n\nInclude colour names and show examples\n\nOne of the most common annoyances I\u2019ve heard from people who are colour-blind is that they often have difficulty purchasing clothing and they will sometimes need to ask another person for a second opinion on what the colour of the clothing might actually be. While it\u2019s easier to shop online than in a physical store, there are still accessibility issues to consider on shopping websites.\n\nLet\u2019s say you\u2019ve got a website that sells T-shirts. If you only show a photo of the shirt, it may be impossible for a person to tell what colour the shirt really is. For clarification, be sure to reference the name of the colour in the description of the product.\n\n\n\nUnited Pixelworkers does a great job of following this rule. The St. John\u2019s T-shirt has a quirky palette inspired by the unofficial pink, white and green Newfoundland flag, and I can imagine many people not liking it.\n\nAnother common problem occurs when a colour filter has been added to a product search. Here\u2019s an example from a clothing website with unlabelled colour swatches, and how that might look to someone with deuteranopia-type colour blindness.\n\n\n\nThe colour search filter below, from the H&M website, is much better since it uses names instead.\n\n\n\nAt first glance, Urban Outfitters also uses unlabelled colour swatches on product pages (below), but on closer inspection, the colour name is displayed on hover. This isn\u2019t an ideal solution, because although it\u2019ll work on a desktop browser, it won\u2019t work on a touchscreen device where hovering isn\u2019t an option. \n\n\n\nUsing overly fancy colour names, like the ones you might find labelling high-end interior paint can be just as confusing as not using a colour name at all. Names like grape instead of purple don\u2019t really give the viewer any useful information about what the colour actually is on a colour wheel. Is grape supposed to be purple, or could it refer to red grapes or even green? Stick with hue names as much as possible.\n\nAvoid colour-specific instructions\n\nWhen designing forms, avoid labelling required fields only with coloured text. It\u2019s safer to use a symbol cue like the asterisk which is colour-independent. \n\n\n\nA similar example would be directing a user to click a green button to purchase a product. Label your buttons clearly and reference them in the site copy by function, not colour, to avoid confusion.\n\nDon\u2019t rely on colour coding\n\nDesigning accessible maps and infographics can be much more challenging. \n\nDon\u2019t rely on colour coding alone \u2014 try to use a combination of colour and texture or pattern, along with precise labels, and reflect this in the key or legend. Combine a blue background with a crosshatched pattern, or a pink background with a stippled dot \u2014 your users will always have two pieces of information to work with.\n\n\n\nThe map of the London subway system is an iconic image not just in London, but around the world. Unfortunately, it contains some colours that are indistinguishable from each other to a person with a vision problem. This is true not only for the London underground, but also for any other wayfinding system that relies on colour coding as the only key in a legend. \n\n\n\nThere are printable versions of the map available online in black and white, using patterns and shades of black and grey that are distinguishable, but the point is that there would be no need for such a map if it were designed with accessibility in mind from the beginning. And, if you\u2019re a person who has a physical disability as well as a vision problem, the \u201cStep-Free\u201d guide map which shows stations is based on the original coloured map. \n\n\n\nProvide alternatives and customization\n\nWhile it\u2019s best to consider these issues and design your app to be accessible by default, sometimes this might not be possible. Providing alternative styles or allowing users to edit their own colours is a feature to keep in mind.\n\nThe developers of the game Faster Than Light created an alternate colour-blind mode and asked for public feedback to make sure that it passed the test. Not much needed to be done, but you can see they added stripes to the red zones and changed some outlines to blue.\n\n\n\niChat is also a good example. Although by default it uses coloured bubbles to indicate a user\u2019s status (available for chat, away or idle, or busy), included in the preferences is a \u201cUser Shapes to Indicate Status\u201d option, which changes the shape of the standard circles to green circles, yellow triangles and red squares.\n\n\n\nPay attention to contrast  \n\nColours that are similar in value but different in hue may be easy to distinguish between for a user with good vision, but a person who suffers from colour blindness may not be able to tell them apart at all. Proofing your work in greyscale is a quick way to tell if there\u2019s enough contrast between the most important information in your design.\n\nCheck with a simulator\n\nThere are many tools out there for simulating different types of colour blindness, and it\u2019s worth checking your design to catch any potential problems up front. \n\nOne is called Sim Daltonism and it\u2019s available for Mac OS X. It\u2019ll show a pop-up preview next to your cursor and you can choose which type of colour blindness you want to test from a drop-down menu. \n\n\n\nYou can also proof for the two most common types of colour blindness right in Photoshop or Illustrator (CS4 and later) while you\u2019re designing. \n\n\n\nThe colour contrast check tool from designer and developer Jonathan Snook gives you the option to enter a colour code for a background, and a colour code for text, and it\u2019ll tell you if the colour contrast ratio meets the Web Content Accessibility Guidelines 2.0. You can use the built-in sliders to adjust your colours until they meet the compliant contrast ratios. This is a great tool to test your palette before going live.\n\n\n\nFor live websites, you can use the accessibility tool called WAVE, which also has a contrast checker. It\u2019s important to keep in mind, though, that while WAVE can identify contrast errors in text, other things can slip through, so a site that passes the test does not automatically mean it\u2019s accessible in reality.\n\nFor example, the contrast checker here doesn\u2019t notice that our red link in the introduction isn\u2019t underlined, and therefore could blend into the surrounding paragraph text. \n\n\n\nI know that once I started getting into the habit of checking my work in a simulator, I became more mindful of any potential problem areas and it was easier to avoid them up front. It\u2019s also made me question everything I see around me and it sends red flags off in my head if I think it\u2019s a serious colour blindness fail. Understanding that colour is relative in the planning stages and following these tips will help us make more accessible design for all.", "year": "2012", "author": "Geri Coady", "author_slug": "gericoady", "published": "2012-12-04T00:00:00+00:00", "url": "https://24ways.org/2012/colour-accessibility/", "topic": "design"}
{"rowid": 94, "title": "Using Questionnaires for Design Research", "contents": "How do you ask the right questions? \n\nIn this article, I share a bunch of tips and practical advice on how to write and use your own surveys for design research.\n\nI\u2019m an audience researcher \u2013 I\u2019m not a designer or developer. I\u2019ve spent much of the last thirteen years working with audience data both in creative agencies and on the client-side. I\u2019m also a member of the Market Research Society. I run user surveys and undertake user research for our clients at the design studio I run with my husband \u2013 Mark Boulton Design.\n\nSo let\u2019s get started!\n\nWho are you designing for?\n\nGood web designers and developers appreciate the importance of understanding the audience they are designing or building a website or app for. I\u2019m assuming that because you are reading a quality publication like 24 ways that you fall into this category, and so I won\u2019t begin this article with a lecture.\n\nSuffice it to say, it\u2019s a good idea to involve research of some sort during the life cycle of every project you undertake. I don\u2019t just mean visual or competitor research, which of course is also very important. I mean looking at or finding your own audience or user data. Whether that be auditing existing data or research available from the client, carrying out user interviews, A/B testing, or conducting a simple questionnaire with users, any research is better than none. If you create personas as a design tool, they should always be based on research, so you will need to have plenty of data to hand for that.\n\nWhere do I start?\n\nIn the initial kick-off stages of a project, it\u2019s a good idea to start by asking your client (when working in-house you still have a client \u2013 you might even be the client) what research or audience data they have available. Some will have loads \u2013 analytics, surveys, focus groups and insights \u2013 from talking to customers. Some won\u2019t have much at all and you\u2019ll be hard pressed to find out much about the audience. It\u2019s best to review existing research first without rushing headlong into doing new research. Get a picture of what the data tells you and perhaps get this into a document \u2013 who, what, why and how are they using this website or app? What gaps are there in existing research? What else do you need to know? Then you can decide what else you need to do to plug these gaps. Think about the information first before deciding on the methodology. The rest of my article talks mostly about running self-completion online surveys. You can of course do face-to-face surveys, self-completion written questionnaires or phone polls, but I won\u2019t cover those here. That\u2019s for another article.\n\nWhy run a survey?\n\nSurveys are great for getting a broad picture of your audience. As long as they are designed carefully, you can create an overview of them, how they use the site and their opinions of it, with an idea of which parts of this picture are more important than others. By using a limited amount of open-ended questions, you can also get some more qualitative feedback or insights on your website or app. The clients we work with surprisingly often don\u2019t have much in the way of audience research available, even basic analytics, so I will often suggest running a short survey, just to create a picture of who is out there.\n\nOK, what should I do first?\n\nBefore you rush into writing questions, stop and think about what you\u2019re trying to find out. Remember being in school when you studied science and you had to propose a hypothesis? This could be a starting point \u2013 something to prove or disprove. Or, even better, write a research brief. It doesn\u2019t have to be long; it can be just a sentence that encapsulates what you\u2019re trying to do, like a good creative brief. For the purposes of this article, I created a short, slightly silly survey on Christmas and beliefs in Father Christmas.\n\nMy research brief was:\n\n\n\tTo find out more about people\u2019s beliefs about Father Christmas and their experiences of Christmas.\n\n\nInevitably, as you start thinking of what questions to ask, you will find that you go off at tangents or your client will want you to add in everything but the kitchen sink. In order for your questionnaire not to get too long and lose focus, you could write lists of what it is and what it\u2019s not. This is how I\u2019d apply it to my Christmas questionnaire example:\n\nWhat it is about\n\n\n\tHow people communicate with Father Christmas\n\tIf someone\u2019s background has affected their likelihood of believing in Father Christmas\n\n\nWhat it is not about\n\n\n\tWhat colour to change Father Christmas\u2019s coat to\n\tFather Christmas\u2019s elves\n\n\nLet\u2019s get down to business: the questions. \n\nKinds of questions\n\nThere are two basic kinds of questions: open-ended and closed. Closed questions limit answers by giving the respondent a number of predefined lists of options to choose from. Typically, these are multiple-choice questions with a list of responses. You can either select one or tick all that apply. Another useful type of closed question I often use is a rating scale, where a respondent can assess a situation along a continuum of values. These can also be useful as a measure of advocacy or strength of feeling about something. There is a standard measure called the Net Promoter score, which measures how likely someone is to recommend your product or service to a friend or acquaintance. It\u2019s a useful benchmark as you can compare your scores to others in a similar sector.\n\n\n\nOpen-ended questions often take the form of a statement which requires a response. Generally, respondents are given a text box to fill in. It\u2019s useful to limit this in some way so that people have an idea of how long the expected response should be; for example, a single line for an email address (Q18), or a larger text area for a longer response (Q6).\n\nIf you plan to send your survey out to a large number of people, I would suggest using mostly closed questions, unless you want to spend a long time wading through comments and hand-coded responses. I\u2019d always advise adding a general request at the end of a survey (\u2018Is there anything else you\u2019d like to tell us?\u2019). You\u2019d be surprised how many interesting and insightful comments people will add.\n\nThere are times when it\u2019s better to provide an open-ended text box rather than a predefined list makes assumptions about your audience\u2019s groupings. For example, we ran a short survey for our Gridset beta testers and rather than assume we knew who they were, we decided to ask an open-ended question: \u201cWhat is your current job title?\u201d\n\n\n\nThe analysis took quite a bit longer than responses using a predefined list, but it meant that we were able to make sure we didn\u2019t miss anyone. And next time we run a survey for Gridset, I can use the responses gathered from this survey to help create a predefined list to make analysis easier.\n\nWhat to ask\n\nThe questions to ask depend on what you want to know, but your brief and lists of what the survey is and isn\u2019t should help here. I always ask the design team and client to give me ideas of what they are interested in finding out, and combine this with a mix of new and standard questions I have used in other surveys. I find Survey Monkey\u2019s question bank a very useful source of example questions and help with tricky wording.\n\nI always include simple demographics so I can compare my results to the population at large or internet users as a whole \u2013 just going on age, gender and location can be quite illuminating. For example, with the Christmas survey, I can see that the respondents were typical of the online design and dev community, mainly young and male.\n\nIf appropriate, I add questions on disability, ethnic background, religion and community of interest. Questions about ethnicity, religion, sexual preference, disability and other sensitive subjects can feel awkward and difficult to ask. This is not a good reason to not ask them. Perhaps you\u2019re working for a public sector client, like a local council, so it\u2019s likely you will need to consider groups of people who maybe under-represented, who may have differing views to others, or who you need to look at specifically as a subset.\n\nHow to ask\n\nAlthough they may seem clunky and wordy, it\u2019s often best to use the census wording or professional body wording for such demographic questions. For example, I used the UK census 2011 wording for Wales on my Christmas questionnaire in my questions on religion [PDF] (Q16) and ethnicity [PDF] (Q17). I had to adapt them slightly for the Survey Monkey format \u2013 self-completion online, rather than pen and paper \u2013 which is why \u201cWhite Welsh\u201d came up as the first option for the ethnicity question. For similar questions for US audiences, try the Census Bureau website.\n\nWhen conducting a survey for a project that has a global audience, you need to consider who your primary audience is. For example, I recently created a questionnaire for a global news website. A large proportion of its audience is based in the USA, so I was careful to word things in a way Americans would find familiar. I used the US ethnic background census question wording and options, and looked at data for US competitor news websites to decide which to include.\n\nYou should also consider people whose first language isn\u2019t English. Working as an audience researcher at BBC Wales, every survey we did was bilingual. I\u2019ve also recently run a user survey in Arabic using Google Forms. During this project, we found that while Survey Monkey supports different languages, including Arabic, the text ran left to right with no option to change it to right to left \u2013 an essential when it comes to reading Arabic! If research is a deliverable in a client project, and you know you\u2019ll need to conduct it in a foreign language, always build in extra time for translation at both the questionnaire design and analysis stages. Make sure you also allow for plenty of checks. In this case we had to change to Google Forms after initially creating our survey with Survey Monkey to get the functionality we needed.\n\nLook and feel\n\nThink about the survey as another way your audience will experience your brand. Take care getting the tone of voice right. There are plenty of great articles and books out there about tone of voice \u2013 try Letting Go of the Words by Ginny Redish for starters, or Brand Language by Liz Doig. The basic rule of thumb is to sound like a human, and use clear and friendly language. If, like me, you are lucky enough to work with journalists or copy editors, you should ask for their help, particularly in the preamble, linking text and closing statements. I find it helpful to break my questions down into sections and to have a page for each. I then have an introductory piece of text for each section to guide the respondent through the survey.\n\nYou should also make sure you check with your designers how your survey looks \u2013 use a company logo and branding, and make the typography legible. Many survey apps like Survey Monkey and Google Forms have a progress bar. This is helpful for users to see how far through your survey they are. I generally time the survey and give an indication in the preamble: \u201cThis survey will only take five minutes of your time.\u201d\n\nYou also need to think about how you will technically serve the questionnaire. For example, will it be via email, social media, a pop-up or lightbox on your website, or (not recommended but possible) in an ad space?\n\nEthical considerations\n\nSomething else to think about are any local laws that govern how you collect and store data, such as the Data Protection Act in the UK. As a member of the Market Research Society, I am also obliged to consider its guidelines, but even if you\u2019re not, it\u2019s always a good idea to deal with personal data ethically.\n\nIf you collect personal data that can identify individuals, you must ask their permission to share it with others, and store it securely for no longer than two years. If you want to contact people afterwards, you must ask for their permission. If you ask for email addresses, as I did in question 18, you have a ready-made sample for a further survey, interviews or focus groups. Remember, you shouldn\u2019t survey people under sixteen years old without the permission of their parents or legal guardians, so if you know your website is likely to be used by children, you must ask for verification of age early on, and your survey should close someone answers that they are under sixteen. The ESOMAR guidelines for online research [PDF] are well worth reading, as they go into detail about such issues, as well as privacy guidelines \u2013 using cookies, storing IP addresses, and so on.\n\nTools\n\nUnless you work in-house and have proprietary software, or at a market research agency and you\u2019re using specialist software such as Snap or IBM SPSS Statistics (previously just SPSS), you will need to use a good tool to run your survey, collect your responses and, ideally, help with the analysis. I like Survey Monkey because of the question bank and analysis tools. The software graphs your results and does simple cross-tabbing and filtering. What this means is you can slice the data in more interesting ways and delve a bit deeper. For example, in the Gridset questionnaire I mentioned earlier, I cross-tabbed responses to questions against whether a person worked in-house, for an agency or as a freelancer. \n\nOther well known online tools that I also use from time to time are Wufoo and Google Forms. Smart Surveys is a similar service to Survey Monkey and it\u2019s used by many leading brands in the UK. Snap Surveys mentioned above is a well-established player in the market research scene, used a lot for face-to-face surveys and also on tablets and smartphones.\n\nAnalysis\n\nAnalysis is often overlooked but is as important as the design of the questionnaire. Don\u2019t just rely on looking at the summary report and charts generated as standard by your form or survey software. Spend time with your data. Spend at least a week now and then if you can, looking at the data. Keep coming back to it and tweaking or cutting it a different way to see if there are any different pictures. Slice it up in different ways to reveal new insights. Here is the data from my dummy survey (apart from the open-ended responses). \n\nFor open-ended questions, you can analyse collaboratively. Print and cut out the open-ended responses and do a cluster analysis or affinity sort with a colleague. \n\n\n\nDiscussing the comments helps you to understand them. You will also find the design team are more likely to buy into the research as they have uncovered the insights for themselves. Always make sure to treat open-ended responses sensitively and don\u2019t share anything publicly in a way that identifies the respondent.\n\nWrite a report\n\nNever hand over a dataset to your client without a summary of the findings. Data on its own can be skewed to suit the reader\u2019s needs, and not everyone is able to find the story in a dataset. Even if it\u2019s not a deliverable, it\u2019s always a good idea to capture your findings in a report of some sort. Use graphs sparingly to show really interesting things or to aid the reader\u2019s understanding. I have written a quick dummy report using the data from the Christmas questionnaire so you can see how it\u2019s done.\n\nI highly recommend Brian Suda\u2019s book A Practical Guide to Designing with Data for tips on how to present data effectively, but that\u2019s a subject that benefits a whole article (indeed book) in itself. \n\nI am not a designer. I am a researcher, so I never write design recommendations in a report unless they have been talked about or suggested by the designers I work with. More often, I write up the results and we talk about them and what impact they have on the project or design. Often they lead to more questions or further research.\n\nSo that\u2019s it: a brief introduction to using questionnaires for design research. Here\u2019s a quick summary to remind you what I have talked about, and a list of resources if you\u2019re interested in reading further.\n\nTop 10 things to remember when using questionnaires for design research:\n\n\n\tStart by auditing existing research to identify gaps in data.\n\tWrite a research brief. Work out exactly what you\u2019re trying to find out \u2013 what is the survey about, and what is it not about?\n\tThe two basic kinds of questions are open-ended and closed.\n\tClosed questions limit responses by giving the respondent a number of predefined lists of options to choose from (multiple choice, rating scales, and so on).\n\tOpen-ended questions are often in the form of a statement which requires a response. Always ask one at the end of a questionnaire.\n\tAlways include simple demographics to enable you to compare your sample against the population in general.\n\tIt\u2019s best to use official census or professional body wording for questions on ethnicity, disability and religion.\n\tBe sure to think carefully about your tone of voice and the look of your questionnaire.\n\tPay attention to guidelines and laws on storing personal data, cookies and privacy.\n\tInvest plenty of time in analysis and report writing. Don\u2019t just look at the obvious \u2013 dig deep for more interesting insights.\n\n\nSome useful resources for further study\n\nOnline research\n\n\n\tDesign Research: Methods and Perspectives edited by Brenda Laurel\n\tOnline Research Essentials by Brenda Russell and John Purcell\n\tHandbook of Online and Social Media Research by Ray Poynter\n\tESOMAR guidelines for online research [PDF]\n\tOnline questionnaires\n\n\nMarket research books on questionnaire design\n\n\n\tUsing Questionnaires in Small-Scale Research: A Beginner\u2019s Guide by Pamela Munn\n\tQuestionnaire Design by A N Oppenheim\n\tDeveloping a Questionnaire by Bill Gillham", "year": "2012", "author": "Emma Boulton", "author_slug": "emmaboulton", "published": "2012-12-14T00:00:00+00:00", "url": "https://24ways.org/2012/using-questionnaires-for-design-research/", "topic": "business"}
{"rowid": 79, "title": "Responsive Images: What We Thought We Needed", "contents": "If you were to read a web designer\u2019s Christmas wish list, it would likely include a solution for displaying images responsively. For those concerned about users downloading unnecessary image data, or serving images that look blurry on high resolution displays, finding a solution has become a frustrating quest.\n\nHaving experimented with complex and sometimes devilish hacks, consensus is forming around defining new standards that could solve this problem. Two approaches have emerged.\n\nThe <picture> element markup pattern was proposed by Mat Marquis and is now being developed by the Responsive Images Community Group. By providing a means of declaring multiple sources, authors could use media queries to control which version of an image is displayed and under what conditions:\n\n<picture width=\"500\" height=\"500\">\n  <source media=\"(min-width: 45em)\" src=\"large.jpg\">\n  <source media=\"(min-width: 18em)\" src=\"med.jpg\">\n  <source src=\"small.jpg\">\n  <img src=\"small.jpg\" alt=\"\">\n  <p>Accessible text</p>\n</picture>\n\nA second proposal put forward by Apple, the srcset attribute, uses a more concise syntax intended for use with the <img> element, although it could be compatible with the <picture> element too. This would allow authors to provide a set of images, but with the decision on which to use left to the browser:\n\n<img src=\"fallback.jpg\" alt=\"\" srcset=\"small.jpg 640w 1x, small-hd.jpg 640w 2x, med.jpg 1x, med-hd.jpg 2x \">\n\nEnter Scrooge\n\n\n\tMen\u2019s courses will foreshadow certain ends, to which, if persevered in, they must lead.\nEbenezer Scrooge\n\n\nGiven the complexity of this issue, there\u2019s a heated debate about which is the best option. Yet code belies a certain truth. That both feature verbose and opaque syntax, I\u2019m not sure either should find its way into the browser \u2013 especially as alternative approaches have yet to be fully explored.\n\nSo, as if to dampen the festive cheer, here are five reasons why I believe both proposals are largely redundant.\n\n1. We need better formats, not more markup\n\nAs we move away from designs defined with fixed pixel values, bitmap images look increasingly unsuitable. While simple images and iconography can use scalable vector formats like SVG, for detailed photographic imagery, raster formats like GIF, PNG and JPEG remain the only suitable option.\n\nThere is scope within current formats to account for varying bandwidth but this requires cooperation from browser vendors. Newer formats like JPEG2000 and WebP generate higher quality images with smaller file sizes, but aren\u2019t widely supported.\n\nWhile it\u2019s tempting to try to solve this issue by inventing new markup, the crux of it remains at the file level.\n\nDaan Jobsis\u2019s experimentation with image compression strengthens this argument. He discovered that by increasing the dimensions of a JPEG image while simultaneously reducing its quality, a smaller files could be produced, with the resulting image looking just as good on both standard and high-resolution displays.\n\nThis may be a hack in lieu of a more permanent solution, but it\u2019s applied in the right place. Easy to accomplish with existing tools and without compatibility issues, it has few downsides. Further experimentation in this area should be encouraged, with standardisation efforts more helpful if focused on developing new image formats or, preferably, extending existing ones.\n\n2. Art direction doesn\u2019t belong in markup\n\nA desired benefit of the <picture> markup pattern is to allow for greater art direction. For example, rather than scaling down images on smaller displays to the point that their content is hard to discern, we could present closer crops instead:\n\n\n\nThis can be achieved with CSS of course, although with a download penalty for those parts of an image not shown. This point may be negligible, however, since in the context of adaptable layouts, these hidden areas may end up being revealed anyway.\n\nArt direction concerns design, not content. If we wish to maintain a separation of concerns, including presentation within our markup seems misguided.\n\n3. The size of a display has little relation to the size of an image\n\nBy using media queries, the <picture> element allows authors to choose which characteristics of the screen or viewport to query for different images to be displayed.\n\nIn developing sites at Clearleft, we have noticed that the viewport is essentially arbitrary, with the size of an image\u2019s containing element more important. For example, look at how this grid of images may adapt at different viewport widths:\n\n\n\nAs we build more modular systems, components need to be adaptable in and of themselves. There is a case to be made for developing more contextual methods of querying, rather than those based on attributes of the display.\n\n4. We haven\u2019t lived with the problem long enough\n\nA key strength of the web is that the underlying platform can be continually iterated. This can also be problematic if snap judgements are made about what constitutes an improvement.\n\nThe early history of the web is littered with such examples, be it the perceived need for blinking text or inline typographic styling. To build a platform for the future, additions to it should be carefully considered. And if we want more consistent support across browsers, burdening vendors with an ever increasing list of features seems counterproductive.\n\nOnly once the need for a new feature is sufficiently proven, should we look to standardise it. Before we could declare hover effects, rounded corners and typographic styling in CSS, we used JavaScript as a polyfill. Sure, doing so was painful, but use cases were fully explored, and the CSS specification better reflected the needs of authors.\n\n5. Images and the web aesthetic\n\nThe srcset proposal has emerged from a company that markets its phones as being able to browse the real \u2013 yet squashed down, tapped and zoomable \u2013 web. Perhaps Apple should make its own website responsive before suggesting how the rest of us should do so.\n\nConverserly, while the <picture> proposal has the backing of a few respected developers and designers, it was born out of the work Mat Marquis and Filament Group did for the Boston Globe. As the first large-scale responsive design, this was a landmark project that ignited the responsive web design movement and proved its worth. But it was the first.\n\nIts design shares a vernacular to that of contemporary newspaper websites, with a columnar, image-laden and densely packed layout. Compared to more recent examples \u2013 Quartz, The Next Web and the New York Times Skimmer \u2013 it feels out of step with the future direction of news sites. In seeking out a truer aesthetic for the web in which software interfaces have greater influence, we might discover that the need for responsive images isn\u2019t as great as originally thought.\n\n\n\nBuilding for the future\n\nWith responsive design, we\u2019ve accepted the idea that a fully fluid layout, rather than a set of fixed layouts, is best suited to the web\u2019s unpredictable nature. Current responsive image proposals are antithetical to this approach.\n\nWe need solutions that lack complexity, are device-agnostic and work within existing workflows. Any proposal that requires different versions of the same image to be created, is likely to have to acquiesce under the pressure of reality.\n\nWhile it\u2019s easy to get distracted about the size and quality of an image, and how we might choose to serve it, often the simplest solution is not to include it at all. After years of gluttonous design practice, in which fast connections and expansive display sizes were an accepted norm, we have got use to filling pages with needless images and countless items of page furniture.\n\nTo design more adaptable experiences, the presence of every element needs to be questioned, for its existence requires additional data to be downloaded or futher complexity within a design system. Conditional loading techniques mean that the inclusion of images is no longer a binary choice, but can instead appear in a progressively enhanced manner.\n\nSo here is my proposal. Instead of spending the next year worrying about responsive images, let\u2019s embrace the constraints of the medium, and seek out new solutions that can work within them.", "year": "2012", "author": "Paul Lloyd", "author_slug": "paulrobertlloyd", "published": "2012-12-11T00:00:00+00:00", "url": "https://24ways.org/2012/responsive-images-what-we-thought-we-needed/", "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": 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.

{"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": 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": 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": 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": 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": 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": 87, "title": "Content Planning Demystified", "contents": "The first thing you learn as a junior editor is that you can\u2019t do everything yourself. You must rely on someone else to do at least part of what must be done: the long-range planning, the initial drafting or shooting or recording, the editing, the production, the final polish. All of those pieces of work that belong to someone else take quite a lot of time \u2014 days, weeks, sometimes months. If you\u2019re the sort of person who wrote college term papers the night before they were due, this can come as a bit of a shock. To my twenty-two-year-old self, it certainly did. \n\nIt turns out that the only real way to avoid a trainwreck with editorial work is to get ahead of the trouble, line everything up carefully, and leave oodles of room for all the pieces to connect on time. The same is true of content strategy, content planning, and just about everything to do with content on the web, except for the writing itself \u2014 and that, too, usually takes far longer than anyone expects. If you\u2019re not a professional editor and you suddenly find yourself dealing with content creation, you\u2019re almost certainly going to underestimate the time and effort involved, or to skip something important in the planning process that pops up to bite you later. \n\nWithout good content, it doesn\u2019t matter how well designed or coded your web project is, because it won\u2019t be doing the thing it\u2019s meant to do. And even if content is far from your specialty, you may well end up being the only one willing to coordinate it far enough in advance to avoid a chaotic ending. Whether you\u2019re hiring writers and editors for a big project, working with a small client, or coaxing some editorial help out of a co-worker, getting the planning work done correctly \u2014 and ahead of time \u2014 will allow you to orchestrate a glorious ballet of togetherness, instead of feverishly scraping together something to put on your site when the deadline looms. So get out the graph paper and the pocket protector, because we\u2019re going to go Full Nerd on this problem.\n\nKnow your poison\n\nAnyone who\u2019s seen a project delayed for six months by content trouble, or derailed by content that\u2019s bland and unhelpful, knows this stuff can make you feel like a dead sock. To get ahead of the problem, you\u2019re going to have to learn to spot common problems and plan your way around them. On web projects without a dedicated editorial lead, you\u2019re likely to encounter content that is:\n\n\n\tUseless \u2013 Content that doesn\u2019t serve your readers\u2019 needs in some way is pointless. And because it takes up your time and crowds out genuinely helpful things, it\u2019s actually damaging. The logic is simple: you can make content that\u2019s all about you, and that serves your stated messaging goals, but if no one is motivated to read it, it\u2019s a waste of everyone\u2019s time.\n\tBadly written \u2013 When you publish articles or instructions or other content that is too stiffly formal, overly wordy, hard to understand, offensive, unintentionally cheesy, or otherwise off in tone or style, you\u2019re doing two things. First, you\u2019re weakening the information you\u2019re trying to convey by making it obscure or annoying. Second \u2014 and this one is even more damaging \u2014 you\u2019re demonstrating bad taste. When you get the cultural elements of publishing wrong, you encourage your readers to believe that you either don\u2019t understand them or don\u2019t care about getting it wrong.\n\tGooey \u2013 Content strategists have been talking about structured content (that\u2019s chunks versus blobs) for years. If you\u2019re publishing more than a few dozen pages without thinking through the structure of your content, you\u2019re probably missing a chance to improve your long-term efficiency. If you\u2019re publishing more than a couple of thousand pages without taking care of your content structure, you\u2019re probably doing a lot more manual wrangling (or cumbersome CMS work) than you need to be, especially when it comes to cross-platform publishing.\n\tUnregulated \u2013 If you\u2019re not tracking what works and what doesn\u2019t \u2014 and especially if you don\u2019t know what \u201cworks\u201d means for your project or organization \u2014 you\u2019re almost certainly getting worse results than you should be, for more work.\n\tOverabundant \u2013 As demonstrated by the cinnamon challenge, too much of a delicious thing can be a giant and publicly embarrassing disaster. For most projects and organizations, if you\u2019re making more stuff than your readers can handle, or if you\u2019re spreading your creative and editorial resources too thinly, that\u2019s bad. Spammers, content farms, and barrel-bottom tabloids have their own special math, the side effects of which include insomnia, irritability, and crying in traffic while silently mouthing Wilson Phillips lyrics.\n\n\n\nPrevent all preventable damage\n\nOnce you know what kind of trouble to look for, you can prevent a lot of it by doing some smart planning well before someone starts writing (or recording or shooting video).\n\n\n\tTo prevent uselessness: Know your readers and decide what you\u2019re trying to accomplish \u2014 with your website as a whole, and with each piece of content, always. Once you know what you\u2019re trying to achieve, you can evaluate your work as you go to make sure that it\u2019s actually doing the right thing. (I\u2019ve written a lot more about this for A List Apart and in The Elements of Content Strategy.)\n\tTo prevent bad writing: Establish a consistent and appropriate style using examples (and a style guide if you need one), designate an editor, hire good writers, and make time for quality control. Kate Kiefer\u2019s style guide for MailChimp is a superb example of style-wrangling that everyone can use.\n\tTo prevent repulsive goo: Give your content as much structure as possible, and know how structure relates to your entire publishing ecosystem, including all those mobile devices. Sara Wachter-Boettcher\u2019s Content Everywhere and Karen McGrane\u2019s Content Strategy for Mobile offer brilliant yet friendly introductions to the wide world of structured content.\n\tTo prevent unregulated chaos: Measure everything that matters to your project, your client, your organization, and especially your readers \u2014 not generic measures of someone else\u2019s success. Measure it all regularly. Be disciplined. Adjust at regular intervals. Rick Allen\u2019s series on content strategy analytics is an excellent place to begin (part one; part two).\n\tTo prevent overabundance: Stop trying to do everything and focus on giving your readers just a few things they want and genuinely need. Don\u2019t establish a schedule your writers might not be able to keep, and focus on differentiating yourself with quality, not quantity. (And while you\u2019re at it, scratch the auto-posting to social networks and the cross-posting between them. It\u2019s about as engaging as an automated phone system.)\n\n\nAt a slightly higher level, pick the right content person (or team) for the work. If you really only need a few pages of copy, find a smart writer who does good work for multi-platform readers. If you\u2019re slinging tens of thousands of pages of content, get someone with field experience in high-level editorial planning and the ability to turn blobs into chunks and melted goo into Legos. If you\u2019re starting a project that involves making a lot of content over time, bring in someone with journalism experience (or get your client to do so). \n\n\u201cBut wait!\u201d you may say. \u201cI\u2019m not hiring anyone. I have to do this all myself.\u201d That\u2019s not uncommon at all. The bad news is, you have to learn a bunch of stuff. The good news is, you get to learn a bunch of awesome stuff. Figure out what the project needs, just as though you were going to hire someone, and then give yourself time to get up to speed. If it\u2019s a really complicated project, you\u2019re probably going to have trouble unless you eventually get professional help. But if it\u2019s small and you can do it in steps, you can certainly do much better by giving yourself a plan and working on the things that matter most.\n\n\nPlan for the marathon, not the sprint\n\nLaunching with awesome content is a tiny fraction of a victory, which is why it\u2019s so important that your content not be gooey or unregulated. It also means that if you don\u2019t plan for a realistic publication schedule, you are going to slam into reality in a really unpleasant way not too long after you\u2019ve begun. If you\u2019re asking people to make words (or videos or whatever) for you, they\u2019re going to have to do less of something else, so plan for that beforehand. \n\nAnd while you\u2019re at it, unless publishing is your core business, ditch the feed-the-beast plan that leads to fluffy blog posts and spiritless, unhelpful social media content. It\u2019s antisocial for your reading community, offers short-term gains at best, and will burn you out or lower your standards until you don\u2019t even know you\u2019re doing lousy work. Good content is expensive, no matter how you do it, but spreading yourself too thin is a much worse investment than doing a smaller thing well and gradually building up a body of superb content that people want to share and keep and return to.", "year": "2012", "author": "Erin Kissane", "author_slug": "erinkissane", "published": "2012-12-20T00:00:00+00:00", "url": "https://24ways.org/2012/content-planning-demystified/", "topic": "content"}
{"rowid": 93, "title": "Design Systems", "contents": "The most important part of responsive web design is that, no matter what the viewport width, the content is accessible in an optimum display. The best responsive designs are those that allow you to go from one optimised display to another, but with the feeling that these experiences are part of a greater product whole.\n\nResponsive design: where we\u2019ve been going wrong\n\nResponsive web design was a shock to my web designer system. Those of us who had already been designing sites for mobile probably had the biggest leap to make. We might have been detecting user agents in order to deliver a mobile-specific site, or using the slightly more familiar Bushido technique to deliver sites optimised for device type and viewport size, but either way our focus was on devices. A site was optimised for either a mobile phone or a desktop.\n\nResponsive web design brought us back to pre-table layout fluid sites that expanded or contracted to fit the viewport. This was a big difference to get our heads around when we were so used to designing for fixed-width layouts. Suddenly, an element could be any width or, at least, we needed to consider its maximum and minimum widths. Pixel perfection, while pretty, became wholly unrealistic, and a whole load of designers who prided themselves in detailed and precise designs got a bit scared.\n\nHanging on to our previous processes and typical deliverables led us to continue to optimise our sites for particular devices and provide pixel-perfect mockups for those device widths.\n\nWith all this we were concentrating on devices, not content, deliverables and not process, and making assumptions about users and their devices based on nothing but the width of the viewport.\n\nI don\u2019t think this is a crime, I think it was inevitable.\n\nWe can be up to date with our principles and ideals, but it\u2019s never as easy in practice. That\u2019s why it\u2019s more important than ever to share our successful techniques and processes. Let\u2019s drag each other into modern web design.\n\nDesign systems: the principles\n\nWhat are design systems?\n\nA visual design system is built out of the core components of typography, layout, shape or form, and colour. When considering the design of a whole product, a design system should also include patterns in user flow, content strategy, copy, and tone of voice. These concepts, design decisions or rules, created around the core components are used consistently across your product to create a cohesive feel, whether it\u2019s from one element to another, page to page, or viewport width to viewport width.\n\nResponsive design is one of the most important considerations in the components of a design system. For each component, you must decide what will unite the design across the viewports to maintain that consistent feel, and what parts of the design will differentiate in order to provide a flexible and optimal experience for different viewport sizes.\n\nComponents you might keep the same across viewports\n\n\n\ttypeface\n\tbase unit\n\tcolour\n\tshape/form\n\n\nComponents you might differentiate across viewports\n\n\n\tgrids\n\tlayout\n\tfont size\n\tmeasure (line length)\n\tleading (line height)\n\n\nContent: it must always be the same\n\nThe focus of a design system is the optimum display of content. As Mark Boulton put it, designing \u201ccontent out, not canvas in.\u201d Chris Armstrong puts the emphasis on not designing for viewports but for content \u2013 \u201cwe need to build on what we do know: content.\u201d In order to do this, we must share the same content across all devices and focus on how best to display and represent content through design system components.\n\nThe practical: core visual components\n\nTypography first\n\nWhen you work with a lot of text content, typography is the easiest way to set the visual tone of the design across all viewport widths. It\u2019s likely that you\u2019ll choose one or two typefaces to use across the whole system, but you might change the most legible font size, balanced with the most comfortable measure, as the viewport width changes.\n\nWhere typography meets layout\n\nThe unit on which you choose to base the grid and layout design, font sizes and leading could be based on the typeface, an optimal reading size, or something more arbitrary. Sometimes I\u2019ll choose a unit based on multiples of ten because it makes the maths in the CSS easier. Tim Brown suggests trying a modular scale. Chris Armstrong suggests basing it on your ideal measure, or the width of a fixed item of content such as an ad unit.\n\nGrids and layouts\n\nSensible grid design can be a flexible yet solid foundation for your design system layout component. But you must be wary in responsive design that a grid might not work across all widths: even four columns could make for very cramped content and one-word measures on smaller screens.\n\nMaybe the grid columns are something you differentiate across widths, but you can keep the concept of the grid consistent. If the content has blocks in groups of three, you might decide on a three-column grid which folds down to one column for narrow viewports. If the grid focuses on the idea of symmetry and has a four-column grid on larger viewports, it might fold down to two columns for narrower viewports. These consistencies may seem subtle, not at all obvious to many except the designer, but it\u2019s all these little constants and patterns across the whole of the design system that makes design decisions easier to make (as they adhere to the guiding concepts of your system), and give the product a uniform feel no matter what the device.\n\nShape or form\n\nThe shape or form components are concepts you already use in fixed-width web design for a strong, consistent look and feel. \n\nSince CSS border-radius became widely supported by browsers, a lot of designs feature circle themes. These are very distinctive and can be used across viewport widths giving them the same united feel, even if they\u2019re not used in the same way. This could also apply to border styles, consistent shadows and any number of decorative details and textures. These are the elements that make up the shape or form of a design system.\n\nColour\n\nColour is the most basic way to reinforce a brand and unite experiences across viewports. The same hex colour used system-wide is instantly recognisable, no matter what the viewport width.\n\nThe process\n\nWhile using a design system isn\u2019t necessarily attached to any particular process, it does lend itself to some process ideals.\n\nDetaching design considerations from viewport widths\n\nA design system allows you to focus separately on the components that make up the system, disconnecting the look and feel from the layout. This helps prevent us getting stuck in the rut of the Apple breakpoints (brilliantly coined by Simon Foster) of mobile, tablet and desktop. It also forces us to design for variation in viewport experiences side by side, not one after the other.\n\nDesign in the browser\n\nI can\u2019t start off designing in the browser \u2013 it just doesn\u2019t seem to bring out my creative side (and I\u2019m incredibly envious of you if you can; I just have to start on paper) \u2013 but static mock-ups aren\u2019t the only alternative. Style guides and style tiles are perfect for expressing the concepts of your design system. Pattern libraries could also work well.\n\nMock-ups and breakpoints\n\nAt some point, whether it\u2019s to test your system ideas, or because a client needs help visualising how your system might work, you may end up producing some static mock-ups. It\u2019s not the end of the world, but you must ensure that these consider all the viewports, not just those of the iDevices, or even the devices currently on the market. You need to decide the breakpoints where the states of your design change. The blocks within your content will always have optimum points for their display (based on their hierarchy, density, width, or type of interaction) and so your breakpoints should be based around these points.\n\nThese are probably the ideal points at which to produce static mockups; treat them as snapshots. They\u2019re not necessarily mock-ups, so much as a way of capturing how your design system would be interpreted when frozen at that particular viewport width.\n\nThe future\n\nCreating design systems will give us the flexibility we need for working with the unknown devices of the future. It may be a change in process, but it shouldn\u2019t be too much of a difference in thinking. The pioneers in responsive design have a hard job. Some of these problems may have already been solved in other technologies or industries, but it\u2019s up to the pioneers to find those connections and help us formulate solutions and standards that will make responsive design the best it can possibly be. We need to keep experimenting and communicating, particularly in the area of design, as good user experiences are the true sign of whether our products are a success.", "year": "2012", "author": "Laura Kalbag", "author_slug": "laurakalbag", "published": "2012-12-12T00:00:00+00:00", "url": "https://24ways.org/2012/design-systems/", "topic": "design"}

There\u2019s a belief that early prototyping requires a large amount of time and effort, and isn\u2019t worth an early investment. But it\u2019s not true!\n\nIt\u2019s still normal to spend a significant proportion of time working in wireframes. Given that wireframes are high-level and don\u2019t show much detail, it\u2019s tempting to give up control and responsibility for things like transitions and other things sidelined as visual considerations. These things aren\u2019t expressed well, and perhaps not expressed at all, in wireframes, yet they critically influence the quality of a product. Rapid prototyping early helps to bring sidelined but significant design considerations into focus.\n\nSpeaking fluent design\n\nFluency in a language means being able to speak it confidently and accurately. The Latin root means flow.\n\nBy design fluency, I mean using a set of skills in order to express or communicate an idea. Prototyping is a kind of fluency. It takes designers beyond the domain of grey and white boxes to consider all the elements that make up really good product design.\n\nDesigners shouldn\u2019t be afraid of speaking fluent design. They should think thoroughly about product decisions beyond their immediate role \u2014 not for the sake of becoming some kind of power-hungry design demigod, but because it will lead to better, more carefully considered product design.\n\nWireframes are incomplete sentences\n\nWireframes, once they\u2019ve served their purpose, are a kind of self-imposed restriction.\n\nMostly made out of grey and white boxes, they deliberately express the minimum. Important details \u2014 visuals, nuanced transitions, sounds \u2014 are missing. Their appearance bears little resemblance to the final thing. Responsibility for things that traditionally didn\u2019t matter (or exist) is relinquished. Animations and transitions in particular are increasingly relevant to the mobile designer\u2019s methods. And rather than being fanciful and superfluous visual additions to a product, they help to clarify designs and provide information about context.\n\nWireframes are useful in the early stages. As a designer trying to persuade stakeholders, clients, or peers, sometimes it will be in your interests to only tell half the story. They\u2019re ideal for gauging whether a design is taking the right direction, and they\u2019re the right medium for deciding core things, such as the overall structure and information architecture.\n\nBut spending a long time in wireframes means delaying details to a later stage in the project, or to the end, when the priority is shifted to getting designs out of the door. This leaves little time to test, finesse and perfect things which initially seemed to be less important. I think designers should move away from using wireframes as primary documentation once the design has reached a certain level of maturity.\n\nA prototype is multiple complete sentences\n\nParagraphs, even.\n\nUnlike a wireframe, a prototype is a persuasive storyteller. It can reveal the depth and range of design decisions, not just the layout, but also motion: animations and transitions. If it\u2019s a super-high-fidelity prototype, it\u2019s a perfect vessel for showing the visual design as well. It\u2019s all of these things that contribute to the impression that a product is good\u2026 and useful, and engaging, and something you\u2019d like to use.\n\nA prototype is impressive. A good prototype can help to convince stakeholders and persuade clients. With a compelling demo, people can more easily imagine that this thing could actually exist. \u201cHey\u201d, they\u2019re thinking. \u201cThis might actually be pretty good!\u201d\n\nHow to make a prototype in no time and with no effort\n\nNow, it does take time and effort to make a prototype. However, good news! It used to require a lot more effort. There are tools that make prototyping much quicker and easier.\n\nIf you\u2019re making a mobile prototype (this seems quite likely), you will want to test and show this on the actual device. This sounds like it could be a pain, but there are a few ways to do this that are quite easy.\n\nKeynote, Apple\u2019s presentation software, is an unlikely candidate for a prototyping tool, but surprisingly great and easy for creating prototypes with transitions that can be shown on different devices.\n\nKeynote enables you to do a few useful, excellent things. You can make each screen in your design a slide, which can be linked together to allow you to click through the prototype. You can add customisable transitions between screens. If you want to show a panel that can slide open or closed on your iPad mockup, for example, transitions can also be added to individual elements on the screen. The design can be shown on tablet and mobile devices, and interacted with like it\u2019s a real app. Another cool feature is that you can export the prototype as a video, which works as another effective format for demoing a design.\n\nOverall, Keynote offers a very quick, lightweight way to prototype a design. Once you\u2019ve learned the basics, it shouldn\u2019t take longer than a few hours \u2013 at most \u2013 to put together a respectable clickable prototype with transitions.\n\nDownload the interactive MOV example\n\nHolly icon by Megan Sheehan from The Noun Project\n\nThis is a Quicktime movie exported from Keynote. This version is animated for demonstration purposes, but download the interactive original and you can click the screen to move through the prototype. It demonstrates the basic interactivity of an iPhone app. This anonymised example was used on a project at Fjord to create a master example of an app\u2019s transitions.\n\nPrototyping drawbacks, and perceived drawbacks\n\nIf prototyping is so great, then why do we leave it to the end, or not bother with it at all? There are multiple misconceptions about prototyping: they\u2019re too difficult to make; they take too much time; or they\u2019re inaccurate (and dangerous) documentation.\n\nA prototype is a preliminary model. There should always be a disclaimer that it\u2019s not the real thing to avoid setting up false expectations.\n\nA prototype doesn\u2019t have to be the main deliverable. It can be a key one that\u2019s supported by visual and interaction specifications. And a prototype is a lightweight means of managing and reflecting changes and requirements in a project.\n\nAn actual drawback of prototyping is that to make one too early could mean being gung-ho with what you thought a client or stakeholder wanted, and delivering something inappropriate. To avoid this, communicate, iterate, and keep things simple until you\u2019re confident that the client or other stakeholders are happy with your chosen direction.\n\nThe key throughout any design project is iteration. Designers build iterative models, starting simple and becoming increasingly sophisticated. It\u2019s a process of iterative craft and evolution. There\u2019s no perfect methodology, no magic recipe to follow.\n\nWhat to do next\n\nMake a prototype! It\u2019s the perfect way to impress your friends.\n\nIt can help to advance a brilliant idea with a fraction of the effort of complete development. Sketches and wireframes are perfect early on in a project, but once they\u2019ve served their purpose, prototypes enable the design to advance, and push thinking towards clarifying other important details including transitions.\n\nFor Keynote tutorials, Keynotopia is a great resource. Axure is standard and popular prototyping software many UX designers will already be familiar with; it\u2019s possible to create transitions in Axure. POP is an iPhone app that allows you to design apps on paper, take photos with your phone, and turn them into interactive prototypes. Ratchet is an elegant iPhone prototyping tool aimed at web developers.\n\nThere are perhaps hundreds of different prototyping tools and methods. My final advice is not to get bogged down in (or limited by) any particular tool, but to remember you\u2019re making quick and iterative models. Experiment and play!\n\nPrototyping will push you and your designs to a scary place without limitations.

{"rowid": 88, "title": "Think First, Code Later", "contents": "This is a story that\u2019s best told from the end, and it\u2019s probably one you\u2019re all familiar with.\n\nYou, or someone just like you, have been building a website, probably as part of a skilled and capable team. You\u2019re a front-end developer, focusing on JavaScript \u2013 it\u2019s either your sole responsibility or shared around. It\u2019s quite a big job, been going on for months, and at last it feels like you\u2019re reaching the end of it.\n\nBut, in a brief moment of downtime, you step back and take a look at the code as a whole. You notice that the folder called \u201cjQuery plugins\u201d suddenly looks rather full, and maybe there\u2019s evidence of several methods of doing the same thing; there are loads of little niggly fixes in the bug tracker; and every place you use Ajax the structure of the data is slightly different. You sigh, and your shoulders droop slightly, and you think \u201cYeah, we\u2019ll do that more cleanly next time.\u201d\n\nThe thing is, you probably already know how to rewrite the start of this story to make the ending work better. This situation is not really anyone\u2019s fault \u2013 it\u2019s just an accumulation of all the things you decided along the way, all the things you agreed you\u2019d fix later that have disappeared into the black hole of technical debt, and accomodating all the \u201ccan we just\u2026?\u201d requests from around the team and the client.\n\nSo, the solution to this is easy, right? More interminable planning meetings, more tightly controlled and documented specifications, less freedom to innovate, to try out new ideas and enjoy what you\u2019re doing.\n\nWait, that sounds even less fun than the old way.\n\nMinimum viable planning\n\nActually, planning and specifications are exactly what you need, but the way you go about them can make a real difference, both to the quality of your code, and the quality of your life as a developer. It can be as simple as being a little more thoughtful before starting on any new piece of functionality. Involve your whole team if possible, or at least those working on what you\u2019re doing. Canvass opinions and work out what the solution to the problem might look like first, rather than coding speculatively to find out.\n\nThere are easy ways you can get into this habit of putting the thought and design up front, and it doesn\u2019t have to mean spending more time on the project as a whole. It also doesn\u2019t have to result in reams of functional specifications. Instead, let the code itself form the specification.\n\nAs JavaScript applications become more complex, unit testing is becoming ever more important. So embrace it, whether you prefer QUnit, or Mocha, or any of the other JavaScript testing frameworks out there. The TDD (or test-driven development) pattern is all about writing the tests first and then writing functional code to pass those tests; or, if you prefer, code that meets the specification given by the tests.\n\nSounds like a hassle at first, but once you get into the rhythm of it you should find that the time spent writing tests up front is no greater, and often significantly less, than the time you would have spent fixing bugs afterwards.\n\nIf what you\u2019re working on requires an API between client and server (usually Ajax but this can apply to any method of sending or receiving data) then spend a bit of time with the back-end developer to design the data contracts, before either of you cut any code. Work out what the API endpoints are going to be, and what the data structure you\u2019ll get back from a certain endpoint looks like. A mock JSON object documented on a wiki is enough and it can be atomic. Don\u2019t worry about planning the entire project at once, just plan enough to get on with your current tasks.\n\nDefinition in this way doesn\u2019t have to make your API immutable \u2013 change is still fine \u2013 but if you know roughly where you\u2019re heading, then not only can your team\u2019s efforts become more parallel, but you\u2019re far more likely to have an easier time making it all work. And again, you have a specification \u2013 the shape of the data \u2013 to write your JavaScript against.\n\nPutting everything together, you end up with a logical flow of development, from the specification agreed with the client (your backlog), to the specification agreed with your team (the API contract design), to the specification agreed with your code (your unit tests). Hopefully, there will be ample clues in all of this to inform your front-end library choices, because by then you should have a better picture of what you\u2019re going to need.\n\nWhat the framework?\n\nAs a JavaScript developer predominantly, these are the choices I\u2019m particularly interested in \u2013 how and why you use JavaScript libraries and frameworks, both what you expect from them and what you actually get.\n\nIf we look back at how web development, and specifically JavaScript development has progressed \u2013 from the earliest days of using lines and lines of Dreamweaver code-barf to make an image rollover effect, to today\u2019s large frameworks that handle working with the DOM, Ajax communication and visual effects all in one hit \u2013 the purpose of it is clear: to smooth over the inconsistent bumps between browsers and give a solid, reliable, predictable base on which to put our desired functionality.\n\nUnderstanding what we expect the language as a specification to do, and matching that to what we observe browsers actually doing, and then smoothing out the differences, is a big job. Since the language and the implementations are also changing as we go along, it also feels like a never-ending job. So make full use of this valuable effort. Use jQuery or YUI or anything else you\u2019re comfortable with, but it still pays to think early on about what you need your library to do and what the best choice is to meet that need.\n\nI\u2019ve come in to projects as a fixer and found, to take a recent example, that jQuery UI was being used just to provide a date picker and a modal effect. That\u2019s a lot of code weight to provide two fairly simple pieces of functionality that could easily be covered by smaller plugins. Which isn\u2019t to say that jQuery UI itself is a bad choice, but I could see that it had been included late on just to do those things, whereas a more considered approach would have been to put the library in early and use it more universally.\n\nThere are other choices, too. If you automatically throw in jQuery (or whatever your favourite main library is) to a small site with limited functionality, you might only touch a tiny fraction of its scope. In my own development I started looking at what I actually needed from a JavaScript library. For a simple project like What the Framework?, all jQuery needed to do was listen for .ready() and then perform some light DOM selection before handing over to a client-side MVC framework. So perhaps there was another way to go about this while still avoiding the cross-browser headaches.\n\nDeleting jQuery\n\nBut the jQuery pattern is compelling and familiar. And once you\u2019re comfortable with something, it\u2019s a bit of an effort to force yourself out of that comfort zone and learn. But looking back at my whole career, I realised that I\u2019ve relearned pretty much everything I do, probably several times, since I started out. So it\u2019s worth keeping in mind that learning and trying new things is how development has advanced to where it is now, and how it will keep advancing in the future.\n\nIn the end this lead me to Ender, which is billed as an NPM-style package manager for the browser, letting you search for and manage small, loosely coupled modules and their dependencies, and compile them to one file with a common API.\n\nFor What the Framework I ended up with a set of DOM tools, Underscore and Knockout, all minified into 25kb of JavaScript. This compares really well with 32kb minified for jQuery on its own, and Ender\u2019s use of the dollar variable and the jQuery-like syntax in many modules makes switching over a low-friction experience.\n\nOn more complex projects, where you\u2019re really going to use all the features of something like jQuery, but want to minimise the loading of other dependencies when you don\u2019t need them, I\u2019ve recently started looking at Jam. This uses the RequireJS pattern to compile commonly used code into a library file and then manage dependencies and bring in others on a per-page basis depending on how you need it. Again, it all comes down to thinking about what you need and using it only when you need it. And the configurability of tools like Ender or Jam allow you to be responsive to changing requirements as your project grows.\n\nThere is no right answer\n\nThat\u2019s not to say this way of working automatically makes things easier. It doesn\u2019t. On a large, long-running project or one where future functionality is unknown, it\u2019s still hard to predict and plan for everything \u2013 at least until crystal balls as a service come about. But by including strong engineering practices in your front-end, and trying to minimise technical debt, you\u2019re at least giving yourself a decent safety net to guard against the \u201ccan we just\u2026?\u201d tendencies that are a fact of life.\n\nSo, really, this is not an advocation of using a particular technology or framework, because I can\u2019t tell you what works for you or your team. But what I can tell you is that working this way round has done wonders for my productivity and enthusiasm, both for code quality and for trying out new libraries.

{"rowid": 80, "title": "HTML5 Video Bumpers", "contents": "Video is a bigger part of the web experience than ever before. With native browser support for HTML5 video elements freeing us from the tyranny of plugins, and the availability of faster internet connections to the workplace, home and mobile networks, it\u2019s now pretty straightforward to publish video in a way that can be consumed in all sorts of ways on all sorts of different web devices.\n\nI recently worked on a project where the client had shot some dedicated video shorts to publish on their site. They also had some five-second motion graphics produced to top and tail the videos with context and branding. This pretty common requirement is a great idea on the web, where a user might land at your video having followed a link and be viewing a page without much context.\n\nKnown as bumpers, these short introduction clips help brand a video and make it look a lot more professional.\n\n\n\nAdding bumpers to a video\n\nThe simplest way to add bumpers to a video would be to edit them on to the start and end of the video file itself. Cooking the bumpers into the video file is easy, but should you ever want to update them it can become a real headache. If the branding needs updating, for example, you\u2019d need to re-edit and re-encode all your videos. Not a fun task.\n\nWhat if the bumpers could be added dynamically? That would enable you to use the same bumper for multiple videos (decreasing download time for users who might watch more than one) and to update the bumpers whenever you wanted. You could change them seasonally, update them for special promotions, run different advertising slots, perform multivariate testing, or even target different bumpers to different users.\n\nThe trade-off, of course, is that if you dynamically add your bumpers, there\u2019s a chance that a user in a given circumstance might not see the bumper. For example, if the main video feature was uploaded to YouTube, you\u2019d have no way to control the playback. As always, you need to weigh up the pros and cons and make your choice.\n\nHTML5 bumpers\n\nIf you wanted to dynamically add bumpers to your HTML5 video, how would you go about it? That was the question I found myself needing to answer for this particular client project.\n\nMy initial thought was to treat it just like an image slideshow. If I were building a slideshow that moved between images, I\u2019d use CSS absolute positioning with z-index to stack the images up on top of each other in a pile, with the first image on top. To transition to the second image, I\u2019d use JavaScript to fade the top image out, revealing the second image beneath it.\n\n\n\nNow that video is just a native object in the DOM, just like an image, why not do the same? Stack the videos up with the opening bumper on top, listen for the video\u2019s onended event, and fade it out to reveal the main feature behind. Good idea, right?\n\nWrong\n\nRemember that this is the web. It\u2019s never going to be that easy. The problem here is that many non-desktop devices use native, dedicated video players. Think about watching a video on a mobile phone \u2013 when you play the video, the phone often goes full-screen in its native player, leaving the web page behind. There\u2019s no opportunity to fade or switch z-index, as the video isn\u2019t being viewed in the page. Your page is left powerless. Powerless!\n\n\n\nSo what can we do? What can we control?\n\nThose of us with particularly long memories might recall a time before CSS, when we\u2019d have to use JavaScript to perform image rollovers. As CSS background images weren\u2019t a practical reality, we would use lots of <img> elements, and perform a rollover by modifying the src attribute of the image. \n\nTurns out, this old trick of modifying the source can help us out with video, too. In most cases, modifying the src attribute of a <video> element, or perhaps more likely the src attribute of a source element, will swap from one video to another.\n\nSwappin\u2019 it\n\nLet\u2019s take a deliberately simple example of a super-basic video tag:\n\n<video src=\"mycat.webm\" controls>no fallback coz i is lame, innit.</video>\n\nWe could very simply write a script to find all video tags and give them a new src to show our bumper.\n\n<script>\n\tvar videos, i, l;\n\tvideos = document.getElementsByTagName('video');\n\tfor(i=0, l=videos.length; i<l; i++) {\n\t\tvideos[i].setAttribute('src', 'bumper-in.webm');\n\t}\n</script>\n\nView the example in a browser with WebM support. You\u2019ll see that the video is swapped out for the opening bumper. Great!\n\nBeefing it up\n\nOf course, we can\u2019t just publish video in one format. In practical use, you need a <video> element with multiple <source> elements containing your different source formats.\n\n<video controls>\n    <source src=\"mycat.mp4\" type=\"video/mp4\" />\n    <source src=\"mycat.webm\" type=\"video/webm\" />\n    <source src=\"mycat.ogv\" type=\"video/ogg\" />\n</video>\n\nThis time, our script needs to loop through the sources, not the videos. We\u2019ll use a regular expression replacement to swap out the file name while maintaining the correct file extension.\n\n<script>\n    var sources, i, l, orig;\n    sources = document.getElementsByTagName('source');\n    for(i=0, l=sources.length; i<l; i++) {\n        orig = sources[i].getAttribute('src');\n        sources[i].setAttribute('src', orig.replace(/(w+).(w+)/, 'bumper-in.$2'));\n        // reload the video\n        sources[i].parentNode.load();\n    }\n</script>\n\nThe difference this time is that when changing the src of a <source> we need to call the .load() method on the video to get it to acknowledge the change.\n\nSee the code in action, this time in a wider range of browsers.\n\nBut, my video!\n\nI guess we should get the original video playing again. Keeping the same markup, we need to modify the script to do two things:\n\n\n\tStore the original src in a data- attribute so we can access it later\n\tAdd an event listener so we can detect the end of the bumper playing, and load the original video back in\n\n\nAs we need to loop through the videos this time to add the event listener, I\u2019ve moved the .load() call into that loop. It\u2019s a bit more efficient to call it only once after modifying all the video\u2019s sources.\n\n<script>\nvar videos, sources, i, l, orig;\nsources = document.getElementsByTagName('source');\nfor(i=0, l=sources.length; i<l; i++) {\n    orig = sources[i].getAttribute('src');\n    sources[i].setAttribute('data-orig', orig);\n    sources[i].setAttribute('src', orig.replace(/(w+).(w+)/, 'bumper-in.$2'));\n}\nvideos = document.getElementsByTagName('video');\nfor(i=0, l=videos.length; i<l; i++) {\n    videos[i].load();\n    videos[i].addEventListener('ended', function(){\n        sources = this.getElementsByTagName('source');\n        for(i=0, l=sources.length; i<l; i++) {\n            orig = sources[i].getAttribute('data-orig');\n            if (orig) {\n                sources[i].setAttribute('src', orig);\n            }\n            sources[i].setAttribute('data-orig','');\n        }\n        this.load();\n        this.play();\n    });\n}\n</script>\n\nAgain, view the example to see the bumper play, followed by our spectacular main feature. (That\u2019s my cat, Widget. His interests include sleeping and internet marketing.)\n\nTidying things up\n\nThe final thing to do is add our closing bumper after the main video has played. This involves the following changes:\n\n\n\tWe need to keep track of whether the src has been changed, so we only play the video if it\u2019s changed. I\u2019ve added the modified variable to track this, and it stops us getting into a situation where the video just loops forever.\n\tAdd an else to the event listener, for when the orig is false (so the main feature has been playing) to load in the end bumper. We also check that we\u2019re not already playing the end bumper. Because looping.\n\n\n<script>\nvar videos, sources, i, l, orig, current, modified;\nsources = document.getElementsByTagName('source');\nfor(i=0, l=sources.length; i<l; i++) {\n   orig = sources[i].getAttribute('src');\n   sources[i].setAttribute('data-orig', orig);\n   sources[i].setAttribute('src', orig.replace(/(w+).(w+)/, 'bumper-in.$2'));\n}\nvideos = document.getElementsByTagName('video');\nfor(i=0, l=videos.length; i<l; i++) {\n   videos[i].load();\n   modified = false;\n   videos[i].addEventListener('ended', function(){\n      sources = this.getElementsByTagName('source');\n      for(i=0, l=sources.length; i<l; i++) {\n         orig = sources[i].getAttribute('data-orig');\n         if (orig) {\n            sources[i].setAttribute('src', orig);\n            modified = true;\n         }else{\n            current = sources[i].getAttribute('src');\n            if (current.indexOf('bumper-out')==-1) {\n               sources[i].setAttribute('src', current.replace(/([w]+).(w+)/, 'bumper-out.$2'));\n               modified = true;\n            }else{\n               this.pause();\n               modified = false;\n            }\n         }\n         sources[i].setAttribute('data-orig','');\n      }\n      if (modified) {\n         this.load();\n         this.play();\n      }\n   });\n}\n</script>\n\nYo ho ho, that\u2019s a lot of JavaScript. See it in action \u2013 you should get a bumper, the cat video, and an end bumper.\n\nOf course, this code works fine for demonstrating the principle, but it\u2019s very procedural. Nothing wrong with that, but to do something similar in production, you\u2019d probably want to make the code more modular to ease maintainability. Besides, you may want to use a framework, rather than basic JavaScript. \n\nThe end credits\n\nOne really important principle here is that of progressive enhancement. If the browser doesn\u2019t support JavaScript, the user won\u2019t see your bumper, but they will get the main video.

{"rowid": 89, "title": "Direction, Distance and Destinations", "contents": "With all these new smartphones in the hands of lost and confused owners, we need a better way to represent distances and directions to destinations. The immediate examples that jump to mind are augmented reality apps which let you see another world through your phone\u2019s camera. While this is interesting, there is a simpler way: letting people know how far away they are and if they are getting warmer or colder. \n\nIn the app world, you can easily tap into the phone\u2019s array of sensors such as the GPS and compass, but what people rarely know is that you can do the same with HTML. The native versus web app debate will never subside, but at least we can show you how to replicate some of the functionality progressively in HTML and JavaScript.\n\nIn this tutorial, we\u2019ll walk through how to create a simple webpage listing distances and directions of a few popular locations around the world. We\u2019ll use JavaScript to access the device\u2019s geolocation API and also attempt to access the compass to get a heading. Both of these APIs are documented, to be included in the W3C geolocation API specification, and can be used on both desktop and mobile devices today.\n\nTo get started, we need a list of a few locations around the world. I have chosen the highest mountain peak on each continent so you can see a diverse set of distances and directions. \n\n\n\t\t\n\t\t\tMountain \n\t\t\t\u00b0Latitude \n\t\t\t\u00b0Longitude \n\t\t\n\t\t\n\t\t\tKilimanjaro\n\t\t\t-3.075833\n\t\t\t37.353333\n\t\t\n\t\t\n\t\t\tVinson Massif\n\t\t\t-78.525483\n\t\t\t-85.617147\n\t\t\n\t\t\n\t\t\tPuncak Jaya\n\t\t\t-4.078889\n\t\t\t137.158333\n\t\t\n\t\t\n\t\t\tEverest\n\t\t\t27.988056\n\t\t\t86.925278\n\t\t\n\t\t\n\t\t\tElbrus\n\t\t\t43.355\n\t\t\t42.439167\n\t\t\n\t\t\n\t\t\tMount McKinley\n\t\t\t63.0695\n\t\t\t-151.0074\n\t\t\n\t\t\n\t\t\tAconcagua\n\t\t\t-32.653431\n\t\t\t-70.011083\n\t\t\n\n\nSource: Wikipedia \n\nWe can put those into an HTML list to be styled and accessed by JavaScript to create some distance and directions calculations.\n\nThe next thing we need to do is check to see if the browser and operating system have geolocation support. To do this we test to see if the function is available or not using a single JavaScript if statement.\n\n<script>\n// If this is true, then the method is supported and we can try to access the location\nif (navigator.geolocation) {\n\tnavigator.geolocation.getCurrentPosition(geo_success, geo_error);\n}\n</script>\n\nThe if statement will be false if geolocation support is not present, and then it is up to you to do something else instead as a fallback. For this example, we\u2019ll do nothing since our page should work as is and only get progressively better if more functionality is available. \n\nThe if statement will be true if there is support and therefore will continue inside the curly brackets to try to get the location. This should prompt the reader to accept or deny the request to get their location. If they say no, the second function callback is processed, in this case a function called geo_error; whereas if the location is available, it fires the geo_success function callback.\n\nThe function geo_error(){ } isn\u2019t that exciting. You can handle this in any way you see fit. The success function is more interesting. We get a position object passed into the function which contains a series of exciting attributes, namely the latitude and longitude of the device\u2019s current location.\n\nfunction geo_success(position){\n\tgLat = position.coords.latitude;\n\tgLon = position.coords.longitude;\n}\n\nNow, in the variables gLat and gLon we have the user\u2019s approximate geographical position. We can use this information to start to calculate some distances between where they are and all the destinations.\n\nAt the time of writing, you can also get position.coords.heading, but on Windows and iOS devices this returned NULL. In the future, if and when this is supported, this is also where you can easily grab the compass information.\n\nInside the geo_success function, we want to loop through the HTML to get all of the mountain peaks\u2019 latitudes and longitudes and compute the distance.\n\n...\n$('.geo').each(function(){\n\t// Get the lat/lon from the HTML\n\ttLat = $(this).find('.lat').html()\n\ttLon = $(this).find('.lon').html()\n\n\t// compute the distances between the current location and this points location\n\tdist = distance(tLat,tLon,gLat,gLon);\n\n\t// set the return values into something useful\n\td = parseInt(dist[0]*10)/10;\n\ta = parseFloat(dist[1]);\n\n\t// display the value in the HTML and style the arrow\n\t$(this).find('.distance').html(d+' km away');\n\t$(this).find('.direction').css('-webkit-transform','rotate(-' + a + 'deg)');\n\n\t// store the arc for later use if compass is available\n\t$(this).attr('data-arc',a);\n}\n\nIn the variable d we have the distance between the current location and the location of the mountain peak based on the Haversine Formula. The variable a is the arc, which has a value from 0 to 359.99. This will be useful later if we have compass support. Given these two values we have a distance and a heading to style the HTML.\n\nThe next thing we want to do is check to see if the device has a compass and then get access to the the current heading. As we\u2019ll see, there are several ways to do this, some of which work on certain devices but not others. The W3C geolocation spec says that, along with the coordinates, there are several other attributes: accuracy; altitude; and heading. Heading is the direction to true north, which is different than magnetic north! WebKit and Windows return NULL for the heading value, but WebKit has an experimental method to fetch the heading. If you get into accessing these sensors, you\u2019ll have to try to catch a few of these methods to finally get a value. Assuming you do, we can move on to the more interesting display opportunities.\n\nIn an ideal world, this would succeed and set a variable we\u2019ll call compassHeading to get a value between 0 and 359.99 degrees. Now we know which direction north is, we also know the direction relative to north of the path to our destination, so we can can subtract the two values to get an arrow to display on the screen. But we\u2019re not finished yet: we also need to get the device\u2019s orientation (landscape or portrait) and subtract the correct amount from the angle for the arrow. Once we have a value, we can use CSS to rotate the arrow the correct number of degrees.\n\n-webkit-transform: rotate(-180deg)\n\nNot all devices support a standard way to access compass information, so in the meantime we need to use a work around. On iOS, you can use the experimental event method e.webkitCompassHeading. We want the compass to update in real time as the device is moved around, so we\u2019ll put this inside an event listener.\n\nwindow.addEventListener('deviceorientation', function(e) {\n\t// Loop through all the locations on the page\n\t$('.geo').each(function(){\n\t\t// get the arc value from north we computed and stored earlier\n\t\tdestination_arc = parseInt($(this).attr('data-arc'))\n\t\tcompassHeading = e.webkitCompassHeading + window.orientation + destination_arc;\n\t\t// find the arrow element and rotate it accordingly\n\t\t$(this).find('.direction').css('-webkit-transform','rotate(-' + compassHeading + 'deg)');\t\t\n\t}\n}\n\nAs the device is rotated, the compass arrow will constantly be updated. If you want to see an example, you can have a look at this page which shows the distances to all the peaks on each continent.\n\nWith progressive enhancement, we slowly layer on additional functionality as we go. The reader will first see the list of locations with a latitude and longitude. If the device is capable and permissions allow, it will then compute the distance. If a compass is available, with the correct permissions it will then add the final layer which is direction.\n\nYou should consider this code a stub for your projects. If you are making a hyperlocal webpage with restaurant locations, for example, then consider adding these features. Knowing not only how far away a place is, but also the direction can be hugely important, and since the compass is always active, it acts as a guide to the location. \n\nFuture developments\n\nImprovements to this could include setting a timer and recalling the navigator.geolocation.getCurrentPosition() function and updating the distances. I chose very distant mountains so kilometres made sense, but you can divide again by 1,000 to convert to metres if you are dealing with much nearer places. Walking or driving would change the distances so the ability to refresh would be important. \n\nIt is outside the scope of this article, but if you manage to get this HTML to work offline, then you can make a nice web app which sits on your devices\u2019 homescreens and works even without an internet connection. This could be ideal for travellers in an unknown city looking for your destination. Just with offline storage, base64 encoding and data URIs, it is possible to embed plenty of design and functionality into a small offline webpage.\n\nNow you know how to use JavaScript to look up a destination\u2019s location and figure out the distance and direction \u2013 never get lost again.", "year": "2012", "author": "Brian Suda", "author_slug": "briansuda", "published": "2012-12-19T00:00:00+00:00", "url": "https://24ways.org/2012/direction-distance-and-destinations/", "topic": "code"}

You\u2019re questioning the explicit or implicit value of a product or a service. You\u2019re asking, \u201cWill I get out of it what you want me to pay for it?\u201d You\u2019re questioning the competency, judgement and possibly even integrity of the individual or company that gave you that price, even though you don\u2019t realise it. You might not be saying it explicitly, but what you\u2019re implying is, \u201cHave you made a mistake?\u201d, \u201cAm I getting the best deal?\u201d, \u201cAre you being honest with me?\u201d, \u201cCould I get this cheaper?\u201d\n\nFinally, you\u2019re being dishonest, because deep down you know all too well that there\u2019s no such thing as too expensive. \n\nWhy? \n\nIt doesn\u2019t matter what you\u2019re questioning the price of. It could be a product, a service or the cost of an hour, day or week of someone\u2019s time. Whatever you\u2019re buying, too expensive is always an excuse. Saying it shifts acceptability of a price back to the person who gave it. What you should say, but are too afraid to admit, is:\n\n\n\t\u201cIt\u2019s more money than I wanted to pay.\u201d\n\t\u201cIt\u2019s more than I estimated it would cost.\u201d\n\t\u201cIt\u2019s more than I can afford.\u201d\n\n\nEveryone who\u2019s given a price for a product or service will have been told at some point that it\u2019s too expensive. It\u2019s never comfortable to hear that. Thoughts come thick and fast: \u201cWhat do I do?\u201d \u201cHow do I react?\u201d \u201cDo I really want the business?\u201d \u201cAm I prepared to negotiate?\u201d \u201cHow much am I willing to compromise?\u201d\n\nIt\u2019s easy to be defensive when someone questions a price, but before you react, stay calm and remember that if someone says what you\u2019re offering is too expensive, they\u2019re saying more about themselves and their situation than they are about your price. Learn to read that situation and how to follow up with the right questions.\n\nImagine you\u2019ve quoted someone for a week of your time. \u201cThat\u2019s too expensive,\u201d they respond. How should you handle that? Think about what they might otherwise be saying.\n\n\n\n\u201cIt\u2019s more money than I want to pay\u201d may mean that they don\u2019t understand the value of your service. How could you respond?\n\nStart by asking what similar projects they\u2019ve worked on and the type of people they worked with. Find out what they paid and what they got for their money, because it\u2019s possible what you offer is different from what they had before. Ask if they saw a return on that previous investment. Maybe their problem isn\u2019t with your headline price, but the value they think they\u2019ll receive. Put the emphasis on value and shift the conversation to what they\u2019ll gain, rather than what they\u2019ll spend.\n\nIt\u2019s also possible they can\u2019t distinguish your service from those of your competitors, so now would be a great time to explain the differences. Do you work faster? Explain how that could help them launch faster, get customers faster, make money faster. Do you include more? Emphasise that, and how unique the experience of working with you will be.\n\n\n\n\u201cIt\u2019s more than I estimated it would cost\u201d could mean that your customer hasn\u2019t done their research properly. You\u2019d never suggest that to them, of course, but you should ask how they\u2019ve arrived at their estimate. Did they base it on work they\u2019ve purchased previously? How long ago was that? Does it come from comparable work or from a different sector?\n\nHelp your customer by explaining how you arrived at your estimate. Break down each element and while you\u2019re doing that, emphasise the parts of your process that you know will appeal to them. If you know that they\u2019ve had difficulty with something in the past, explain how your approach will benefit them. People almost always value a positive experience more than the money they\u2019ll save.\n\n\n\n\u201cIt\u2019s more than I can afford\u201d could mean they can\u2019t afford what you offer at all, but it could also mean they can\u2019t afford it right now or all at once. So ask if they could afford what you\u2019re asking if they spread payment over a longer period? Ask, \u201cWould that mean you\u2019ll give me the business?\u201d\n\nIt\u2019s possible they\u2019re asking for too much for what they can afford to pay. Will they compromise? Can you reach an agreement on something less? Ask, \u201cIf we can agree what\u2019s in and what\u2019s out, will you give me the business?\u201d\n\nWhat can they afford? When you know, you\u2019re in a good position to decide if the deal makes good business sense, for both of you. Ask, \u201cIf I can match that price, will you give me the business?\u201d\n\nThere\u2019s no such thing as \u201ca bit rich\u201d, only ways for you to get to know your customer better. There\u2019s no such thing as \u201cover-priced\u201d,\u00a0only opportunities for you to explain yourself better. You should relish those opportunities. There\u2019s really also no such thing as \u201ctoo expensive\u201d, just ways to set the tone for your relationship and help you develop that relationship to a point where money will be less of a deciding factor.\n\nUnfinished Business\n\nJoin me and my co-host Anna Debenham next year for Unfinished Business, a new discussion show about the business end of working in web, design and creative industries.", "year": "2012", "author": "Andy Clarke", "author_slug": "andyclarke", "published": "2012-12-23T00:00:00+00:00", "url": "https://24ways.org/2012/monkey-business/", "topic": "business"}
{"rowid": 82, "title": "Being Prepared To Contribute", "contents": "\u201cYou\u2019ll figure it out.\u201d The advice my dad gives has always been the same, whether addressing my grade school homework or paying bills after college. If I was looking for a shortcut, my dad wasn\u2019t going to be the one to provide it.\n\nWhen I was a kid it infuriated the hell out of me, but what I then perceived to be a lack of understanding turned out to be a keystone in my upbringing. As an adult, I realize the value in not receiving outright solutions, but being forced to figure things out. \n\nEven today, when presented with a roadblock while building for the web, I am temped to get by with the help of the latest grid system, framework, polyfill, or plugin. In and of themselves these resources are harmless, but before I can drop them in, those damn words still echo in the back of my mind: \u201cYou\u2019ll figure it out.\u201d\n\nI know that if I blindly implement these tools as drag and drop solutions I fail to understand the intricacies behind how and why they were built; repeatedly using them as shortcuts handicaps my skill set. When I solely rely on the tools of others, my work is at their mercy, leaving me less creative and resourceful, and, thus, less able to contribute to the advancement of our industry and community. \n\nOne of my favorite things about this community is how generous and collaborative it can be. I\u2019ve loved seeing FitVids used all over the web and regularly improved upon at Github. I bet we can all think of a time where implementing a shared resource has benefitted our own work and sanity. Because these resources are so valuable, it\u2019s important that we continue to be a part of the conversation in order to further develop solutions and ideas. It\u2019s easy to assume there\u2019s someone smarter or more up-to-date in any one area, but with a degree of understanding and perspective, we can all participate. \n\nThis open form of collaboration is in our web DNA. After all, its primary purpose was to promote the exchange and development of new ideas.\n\n\n\tTim Berners-Lee proposed a global hypertext project, to be known as the World Wide Web. Based on the earlier \u201cEnquire\u201d work, it was designed to allow people to work together by combining their knowledge in a web of hypertext documents.\n\n\nI\u2019m delighted to find that this spirit of collaborative ingenuity is alive and well on the web today. Take the story of Off Canvas as an example. I was at an ATX Dribbble meet up where I met Jason Weaver and chatted to him about his recent work on the responsive layout prototype, Off Canvas. Jason said he came across a post by Luke Wroblewski outlining the idea and saw this:\n\n\n\tIf anyone is interested in building a complete example of this approach using responsive Web design techniques, let me know!\n\n\nFrom there Luke recounts: \n\n\n\tWe went back and forth on email, with me laying out ideas and Jason doing all the hard work to see if they can be done and improving them bit by bit! Once we got to something we both liked, I wrote up an article explaining things and he hosted the examples.\n\n\nLuke took the time to clearly outline and diagram his ideas, and Jason responded with a solid proof of concept that has evolved into a tool we all have at our disposal. Victory!\n\nI have also benefitted from comrades who have taken an idea of mine into development. After blogging about some concerns in regards to maintaining hierarchy as media queries are used to shift layouts, Jordan Moore rebounded with some responsive demos where he used flexbox to (re)order content as viewport sizing changes.\n\nSimilar stories can be found behind the development of things like FitVids, FitText, and Molten Leading. I love this pattern of collaboration because it involves a fairly specific process:\n\n\n\tInitial idea or prototype is outlined or built, then shared\n\tDiscuss\n\tSomeone develops or improves it, then shares it\n\tDiscuss\n\tSomeone else develops or improves it, then shares it.\n\tInfinity.\n\n\nThis is what the web looks like when we build it together, and I\u2019d argue that steps 2+ are absolutely crucial. A web where everyone develops their own ideas and tools independent of one another is like a room full of people talking and no one listening. \n\n\n\nThe pattern itself mimics a literal web structure, and ideally we\u2019d be able to follow a strand from one idea to the next and so on.\n\nBlessed are the curators\n\nSometimes those lines aren\u2019t easy to find or follow. Thankfully, there are people who painstakingly log each experiment and index much of what\u2019s out there. Chris Coyier does this with CSS in general, and Brad Frost is doing this for responsive and multi-device design with his Pattern Library. Seriously, take a look at this page and imagine what it would take to find, track and organize the progression of each of these resources yourself. I\u2019d argue that ongoing collections like these are more valuable than the sum of their parts when they are updated regularly as opposed to a top ten tips blog post format.\n\nHere\u2019s my soapbox\n\nHere are a few things I appreciate about how things are shared and contributed online. And yes, I could do way better at all of them myself.\n\n\n\tConcise write-ups: honor others\u2019 time by getting to the point. Not every idea or solution needs two thousand words to convey fully. I love long-form posts, but there\u2019s a time and a place for them.\n\tVisual aids: if a quick illustration, screenshot, or graphic helps illustrate your point or problem, yes please.\n\n\nBy the way, Luke Wroblewski rules the school on both of these.\n\n\n\tDemo it: host it yourself, or put it on CodePen or JS Bin for others to see.\n\tPut it on Github: share and improve with the rest of the community. Consider, however, that because someone puts something on Github doesn\u2019t mean they\u2019re forever bound to provide support or instruction.\n\n\nThis isn\u2019t a call for everyone to learn everything all the time, but if you\u2019re curious or interested in something, skip the shortcut and get your hands dirty: sketch, prototype, question, debate, fork, and share. Figuring these things out on our own makes us valuable contributors to the web \u2013 the thing that ultimately we\u2019re all trying to figure out together.", "year": "2012", "author": "Trent Walton", "author_slug": "trentwalton", "published": "2012-12-03T00:00:00+00:00", "url": "https://24ways.org/2012/being-prepared-to-contribute/", "topic": "process"}
