{"rowid": 231, "title": "Designing for iOS: Life Beyond Media Queries", "contents": "Although not a new phenomenon, media queries seem to be getting a lot attention online recently and for the right reasons too \u2013 it\u2019s great to be able to adapt a design with just a few lines of CSS \u2013 but many people are relying only on them to create an iPhone-specific version of their website. \n\nI was pleased to hear at FOWD NYC a few weeks ago that both myself and Aral Balkan share the same views on why media queries aren\u2019t always going to be the best solution for mobile. Both of us specialise in iPhone design ourselves and we opt for a different approach to media queries. The trouble is, regardless of what you have carefully selected to be display:none; in your CSS, the iPhone still loads everything in the background; all that large imagery for your full scale website also takes up valuable mobile bandwidth and time.\n\nYou can greatly increase the speed of your website by creating a specific site tailored to mobile users with just a few handy pointers \u2013 media queries, in some instances, might be perfectly suitable but, in others, here\u2019s what you can do.\n\nRedirect your iPhone/iPod Touch users\n\nTo detect whether someone is viewing your site on an iPhone or iPod Touch, you can either use JavaScript or PHP. \n\nThe JavaScript \n\nif((navigator.userAgent.match(/iPhone/i)) || (navigator.userAgent.match(/iPod/i))) { \n if (document.cookie.indexOf(\"iphone_redirect=false\") == -1) window.location = \"http://mobile.yoursitehere.com\"; \n}\n\nThe PHP\n\nif(strstr($_SERVER['HTTP_USER_AGENT'],'iPhone') || strstr($_SERVER['HTTP_USER_AGENT'],'iPod')) \n{\n header('Location: http://mobile.yoursitehere.com');\n exit();\n}\n\nBoth of these methods redirect the user to a site that you have made specifically for the iPhone. At this point, be sure to provide a link to the full version of the website, in case the user wishes to view this and not be thrown into an experience they didn\u2019t want, with no way back.\n\nTailoring your site\n\nSo, now you\u2019ve got 320\u2009\u00d7\u2009480 pixels of screen to play with \u2013 and to create a style sheet for, just as you would for any other site you build. There are a few other bits and pieces that you can add to your code to create a site that feels more like a fully immersive iPhone app rather than a website.\n\nRetina display\n\nWhen building your website specifically tailored to the iPhone, you might like to go one step further and create a specific style sheet for iPhone 4\u2019s Retina display. Because there are four times as many pixels on the iPhone 4 (640\u2009\u00d7\u2009960 pixels), you\u2019ll find specifics such as text shadows and borders will have to be increased. \n\n\n\n(Credit to Thomas Maier)\n\nPrevent user scaling\n\nThis declaration, added into the , stops the user being able to pinch-zoom in and out of your design, which is perfect if you are designing to the exact pixel measurements of the iPhone screen. \n\n\n\nDesigning for orientation \n\nAs iPhones aren\u2019t static devices, you\u2019ll also need to provide a style sheet for horizontal orientation. We can do this by inserting some JavaScript into the as follows: \n\n\n\nYou can also specify orientation styles using media queries. This is absolutely fine, as by this point you\u2019ll already be working with mobile-specific graphics and have little need to set a lot of things to display:none;\n\n\n\n\n\nRemove the address and status bars, top and bottom\n\nTo give you more room on-screen and to make your site feel more like an immersive web app, you can place the following declaration into the of your document\u2019s code to remove the address and status bars at the top and bottom of the screen. \n\n\n\nMaking the most of inbuilt functions\n\nSimilar to mailto: e-mail links, the iPhone also supports another two handy URI schemes which are great for enhancing contact details. When tapped, the following links will automatically bring up the appropriate call or text interface:\n\nCall us\nText us\n\niPhone-specific Web Clip icon\n\nAlthough I believe them to be fundamentally flawed, since they rely on the user bookmarking your site, iPhone Web Clip icons are still a nice touch. You need just two declarations, again in the of your document:\n\n\n\n\nFor iPhone 4 you\u2019ll need to create a 114\u2009\u00d7\u2009114 pixels icon; for a non-Retina display, a 57\u2009\u00d7\u200957 pixels icon will do the trick.\n\nPrecomposed \n\nApple adds its standard gloss \u2018moon\u2019 over the top of any icon. If you feel this might be too much for your particular icon and would prefer a matte finish, you can add precomposed to the end of the apple-touch-icon declaration to remove the standard gloss. \n\n\n\nWrapping up\n\nMedia queries definitely have their uses. They make it easy to build a custom experience for your visitor, regardless of their browser\u2019s size. For more complex sites, however, or where you have lots of imagery and other content that isn\u2019t necessary on the mobile version, you can now use these other methods to help you out. Remember, they are purely for presentation and not optimisation; for busy people on the go, optimisation and faster-running mobile experiences can only be a good thing. \n\nHave a wonderful Christmas fellow Webbies!", "year": "2010", "author": "Sarah Parmenter", "author_slug": "sarahparmenter", "published": "2010-12-17T00:00:00+00:00", "url": "https://24ways.org/2010/life-beyond-media-queries/", "topic": "code"}
{"rowid": 229, "title": "Sketching to Communicate", "contents": "As a web designer I\u2019ve always felt that I\u2019d somehow cheated the system, having been absent on the day God handed out the ability to draw. I didn\u2019t study fine art, I don\u2019t have a natural talent to effortlessly knock out a realistic bowl of fruit beside a water jug, and yet somehow I\u2019ve still managed to blag my way this far. I\u2019m sure many of you may feel the same.\n\nI had no intention of becoming an artist, but to have enough skill to convey an idea in a drawing would be useful. Instead, my inadequate instrument would doodle drunkenly across the page leaving a web of unintelligible paths instead of the refined illustration I\u2019d seen in my mind\u2019s eye. This \u2013 and the natural scrawl of my handwriting \u2013 is fine (if somewhat frustrating) when it\u2019s for my eyes only but, when sketching to communicate a concept to a client, such amateur art would be offered with a sense of embarrassment. So when I had the opportunity to take part in some sketching classes whilst at Clearleft I jumped at the chance.\n\nWhy sketch?\n\nIn UX workshops early on in a project\u2019s life, sketching is a useful and efficient way to convey and record ideas. It\u2019s disposable and inexpensive, but needn\u2019t look amateur. A picture may be worth a thousand words, but a well executed sketch of how you\u2019ll combine funny YouTube videos with elephants to make Lolephants.com could be worth millions in venture capital. Actually, that\u2019s not bad\u2026 ;-)\n\nAlthough (as you will see) the basics of sketching are easy to master, the kudos you will receive from clients for being a \u2018proper designer\u2019 makes it worthwhile!\n\nWhere to begin?\n\nStart by not buying yourself a sketch pad. If you were the type of child who ripped the first page out of a school exercise book and started again if you made even a tiny mistake (you\u2019re not alone!), Wreck This Journal may offer a helping hand. Practicing on plain A4 paper instead of any \u2018special\u2019 notepad will make the process a whole lot easier, no matter how deliciously edible those Moleskines look.\n\nDo buy yourself a black fine-liner pen and a set of grey Pro Markers for shading. These pens are unlike any you will have used before, and look like blended watercolours once the ink is dry. Although multiple strokes won\u2019t create unsightly blotches of heavy ink on the page, they will go right through your top sheet so always remember to keep a rough sheet in the second position as an ink blotter.\n\n photo by Tom Harrison\n\nDon\u2019t buy pencils to sketch with, as they lack the confidence afforded by the heavy black ink strokes of marker pens and fine-liners.\n\nIf you\u2019re going to be sketching with clients then invest in some black markers and larger sheets of paper. At the risk of sounding like a stationery brand whore, Sharpies are ideal, and these comedy-sized Post-Its do the job far better than cheaper, less sticky alternatives. Although they\u2019re thicker than most standard paper, be sure to double-layer them if you\u2019re writing on them on a wall, unless you fancy a weekend redecorating your client\u2019s swanky boardroom.\n\nThe best way to build confidence and improve your sketching technique is, obviously, to practise. Reading this article will be of no help unless you repeat the following examples several times each. Go grab a pen and some paper now, and notice how you improve within even a short period of time.\n\nSketching web UI\n\nMost elements of any website can be drawn as a combination of geometric shapes.\n\n photo by Nathanael Boehm\n\nCircles\n\nTo draw a circle, get in position and start by resting your hand on the page and making the circular motion a few times without putting pen to paper. As you lower your pen whilst continuing the motion, you should notice the resulting shape is more regular than it otherwise would have been.\n\nSquares and rectangles\n\nDraw one pair of parallel lines first, followed by the others to complete the shapes. Slightly overlap the ends of the lines to make corners feel more solid than if you were to leave gaps. If you\u2019re drawing a container, always draw the contents first, that way it won\u2019t be a squash to fit them in. If you\u2019re drawing a grid (of thumbnails, for instance), draw all parallel lines first as a series of long dashes to help keep line lengths and angles consistent.\n\n\n\nShadows\n\nTo lift elements from the page for emphasis, add a subtle shadow with a grey marker. For the most convincing look, assume the light source to be at the top left of the page \u2013 the shadow should simply be a thick grey line along the bottom and up the right edge of your shape. If the shape is irregular, the shadow should follow its outline. This is a good way to emphasise featured items, speech bubbles, form buttons, and so on.\n\n\n\nSketching ideas\n\nArrows\n\nUse arrows to show steps in a process or direction of movement. Giving shadows a 3-D feel, or adding a single colour, will help separate them from the rest of the sketch.\n\n\n\nFaces\n\nStart by drawing the circle. The direction of the nose (merely a point) indicates the direction of the person\u2019s gaze. The eyes and mouth show emotion: more open and curvy for happy thoughts; more closed and jagged for angry thoughts. Try out a few shapes and see what emotions they convey.\n\n\n\nPeople\n\nRemember, we\u2019re aiming for communication rather than realism here. A stick man would be fine. Give him a solid body, as shown in this example, and it becomes easier to pose him.\n\n\n\nI know you think hands are hard, but they\u2019re quite important to convey some ideas, and for our purposes we don\u2019t need to draw hands with any detail. An oval with a stick does the job of a pointing hand. Close-ups might need more fingers showing, but still don\u2019t require any degree of realism.\n\nSignage\n\nDon\u2019t be afraid to use words. We\u2019re sketching to communicate, so if the easiest way to show an office block is a building with a big \u2018office\u2019 sign on the roof, that\u2019s fine!\n\n\n\nLabels\n\nLikewise, feel free to label interactions. Use upper-case letters for legibility and slightly angle the horizontal bars upwards to create a more positive feel.\n\nClich\u00e9s\n\nClich\u00e9s are your friend! Someone\u2019s having an idea? Light bulb above the head. Computer\u2019s crashed? Cloud of smoke with \u201c$\u00a3%*!\u201d\n\n\n\n\n\nIt\u2019s good to practise regularly. Try applying these principles to still life, too. Look around you now and draw the cup on the table, or the books on the shelf. Think of it as a combination of shapes and aim for symbolism rather than realism, and it\u2019s not as hard as you\u2019d think.\n\nI hope this has given you the confidence to give it a shot, and the ability to at least not be mortified with the results!\n\nTip: If you\u2019re involving clients in design games like Leisa Reichelt\u2019s \u2018Design Consequences\u2019 it may be wise to tone down the quality of your drawings at that point so they don\u2019t feel intimidated. Remember, it\u2019s important for them to feel at ease with the idea of wireframing in front of you and their colleagues, no matter how bad their line work.\n\nFor more information see davegrayinfo.com \u2013 Dave Gray taught me everything I know :-)", "year": "2010", "author": "Paul Annett", "author_slug": "paulannett", "published": "2010-12-19T00:00:00+00:00", "url": "https://24ways.org/2010/sketching-to-communicate/", "topic": "business"}
{"rowid": 222, "title": "Golden Spirals", "contents": "As building blocks go, the rectangle is not one to overwhelm the designer with decisions. On the face of it, you have two options: you can set the width, and the height. But despite this apparent simplicity, there are combinations of width and height that can look unbalanced. If a rectangle is too tall and slim, it might appear precarious. If it is not tall enough, it may simply look flat. But like a guitar string that\u2019s out of tune, you can tweak the proportions little by little until a rectangle feels, as Goldilocks said, just right.\n\nA golden rectangle has its height and width in the golden ratio, which is approximately 1:1.618. These proportions have long been recognised as being aesthetically harmonious. Whether through instruction or by intuition, artists have understood how to exploit these proportions over the centuries. Examples can be found in classical architecture, medieval book construction, and even in the recent #newtwitter redesign.\n\nA mathematical curiosity\n\n\n\n\n\n\n\nThe golden rectangle is unique, in that if you remove a square section from it, what is left behind is itself a golden rectangle. The removal of a square can be repeated on the rectangle that is left behind, and then repeated again, as many times as you like. This means that the golden rectangle can be treated as a building block for recursive patterns. In this article, we will exploit this property to build a golden spiral, using only HTML and CSS.\n\nThe markup\n\nThe HTML we\u2019ll use for this study is simply a series of nested
\n\n\nThe first of these has the class cycle, and so does every fourth ancestor thereafter. The spiral completes a cycle every four steps, so this class allows styles to be reused on
s that appear at the same position in each cycle.\n\nGolden proportions\n\nTo create our spiral we are going to exploit the unique properties of the golden rectangle, so our first priority is to ensure that we have a golden rectangle to begin with. If we pick a length for the short edge \u2013 say, 288 pixels \u2013 we can then calculate the length of the long edge by multiplying this value by 1.618. In this case, 288\u2009\u00d7\u20091.618\u2009=\u2009466, so our starting point will be a
with these properties:\n\n#container > div {\n width: 466px;\n height: 288px;\n}\n\nThe greater than symbol is used here to single out the immediate child of the #container element, without affecting the grandchild or any of the more distant descendants.\n\nWe could go on to specify the precise pixel dimensions of every child element, but that means doing a lot of sums. It would be much easier if we just specified the dimensions for each element as a percentage of the width and height of its parent. This also has the advantage that if you change the size of the outermost container, all nested elements would be resized automatically \u2013 something that we shall exploit later.\n\n\n\n\n\n\n\nThe approximate value of 38.2% can be derived from (100\u2009\u00d7\u20091\u2009\u2212\u2009phi)\u2009\u00f7\u2009phi, where the Greek letter phi (\u03d5) stands for the golden ratio. The value of phi can be expressed as phi\u2009=\u2009(1\u2009+\u2009\u221a5\u2009)\u2009\u00f7\u20092, which is approximately 1.618. You don\u2019t have to understand the derivation to use it. Just remember that if you start with a golden rectangle, you can slice 38.2% from it to create a new golden rectangle.\n\nThis can be expressed in CSS quite simply:\n\n.cycle,\n.cycle > div > div {\n height: 38.2%;\n width: 100%;\n}\n.cycle > div,\n.cycle > div > div > div {\n width: 38.2%;\n height: 100%;\n}\n\nYou can see the result so far by visiting Demo One. With no borders or shading, there is nothing to see yet, so let\u2019s address that next.\n\nShading with transparency\n\nWe\u2019ll need to apply some shading to distinguish each segment of the spiral from its neighbours. We could start with a white background, then progress through shades of grey: #eee, #ddd, #ccc and so on, but this means hard-coding the background-color for every element. A more elegant solution would be to use the same colour for every element, but to make each one slightly transparent.\n\nThe nested
s that we are working with could be compared to layers in Photoshop. By applying a semi-transparent shade of grey, each successive layer can build on top of the darker layers beneath it. The effect accumulates, causing each successive layer to appear slightly darker than the last. In his 2009 article for 24 ways, Drew McLellan showed how to create a semi-transparent effect by working with RGBA colour. Here, we\u2019ll use the colour black with an alpha value of 0.07.\n\n#container div { background-color: rgba(0,0,0,0.07) }\n\nNote that I haven\u2019t used the immediate child selector here, which means that this rule will apply to all
elements inside the #container, no matter how deeply nested they are. You can view the result in Demo Two. As you can see, the golden rectangles alternate between landscape and portrait orientation.\n\n\n\nDemo Three).\n\n\n\nCSS3 specification indicates that a percentage can be used to set the border-radius property, but using percentages does not achieve consistent results in browsers today. Luckily, if you specify a border-radius in pixels using a value that is greater than the width and height of the element, then the resulting curve will use the shorter length side as its radius. This produces exactly the effect that we want, so we\u2019ll use an arbitrarily high value of 10,000 pixels for each border-radius:\n\n.cycle {\n border-radius: 0px;\n border-bottom-left-radius: 10000px;\n}\n.cycle > div {\n border-radius: 0px;\n border-bottom-right-radius: 10000px;\n}\n.cycle > div > div {\n border-radius: 0px;\n border-top-right-radius: 10000px;\n}\n.cycle > div > div > div {\n border-radius: 0px;\n border-top-left-radius: 10000px;\n}\n\nNote that the specification for the border-radius property is still in flux, so it is advisable to use vendor-specific prefixes. I have omitted them from the example above for the sake of clarity, but if you view source on Demo Four then you\u2019ll see that the actual styles are not quite as brief.\n\n\n\n\n\n\n\nFilling the available space\n\nWe have created an approximation of the Golden Spiral using only HTML and CSS. Neat! It\u2019s a shame that it occupies just a fraction of the available space. As a finishing touch, let\u2019s make the golden spiral expand or contract to use the full space available to it.\n\nIdeally, the outermost container should use the full available width or height that could accomodate a rectangle of golden proportions. This behaviour is available for background images using the \u201c background-size: contain; property, but I know of no way to make block level HTML elements behave in this fashion (if I\u2019m missing something, please enlighten me). Where CSS fails to deliver, JavaScript can usually provide a workaround. This snippet requires jQuery:\n\n$(document).ready(function() {\n\tvar phi = (1 + Math.sqrt(5))/2;\n\n\t$(window).resize(function() {\n\t\tvar goldenWidth = windowWidth = $(this).width(),\n\t\t\tgoldenHeight = windowHeight = $(this).height();\n\n\t\tif (windowWidth/windowHeight > phi) {\n\t\t\t// panoramic viewport \u2013 use full height\n\t\t\tgoldenWidth = windowHeight * phi;\n\t\t} else {\n\t\t\t// portrait viewport \u2013 use full width\n\t\t\tgoldenHeight = windowWidth / phi;\n\t\t};\n\n\t$(\"#container > div.cycle\")\n\t\t.width(goldenWidth)\n\t\t.height(goldenHeight);\n\n\t}).resize();\n\n});\n\nYou can view the result by visiting Demo Five.\n\n\n\n\n\n\n\nIs it just me, or can you see an elephant in there?\n\nYou can probably think of many ways to enhance this further, but for this study we\u2019ll leave it there. It has been a good excuse to play with proportions, positioning and the immediate child selector, as well as new CSS3 features such as border-radius and RGBA colours. If you are not already designing with golden proportions, then perhaps this will inspire you to begin.", "year": "2010", "author": "Drew Neil", "author_slug": "drewneil", "published": "2010-12-07T00:00:00+00:00", "url": "https://24ways.org/2010/golden-spirals/", "topic": "design"}
{"rowid": 226, "title": "Documentation-Driven Design for APIs", "contents": "Documentation is like gift wrapping. It seems like superfluous fluff, but your family tends to be rather disappointed when their presents arrive in supermarket carrier bags, so you have to feign some sort of attempt at making your gift look enticing. Documentation doesn\u2019t have to be all hard work and sellotaping yourself to a table \u2013 you can make it useful and relevant.\n\nDocumentation gets a pretty rough deal. It tends to get left until the end of a project, when some poor developer is assigned the \u2018document project\u2019 ticket and wades through each feature of Whizzy New API 3.0 and needs to recall exactly what each method is meant to do. That\u2019s assuming any time is left for documentation at all. The more common outcome resembles last minute homework scribbled on a post-it note, where just the bare bones of what\u2019s available are put out for your users, and you hope that you\u2019ll spot the inconsistencies and mistakes before they do.\n\nWouldn\u2019t it be nicer for everyone if you could make documentation not only outstanding for your users, but also a valuable tool for your development team \u2013 so much so that you couldn\u2019t imagine writing a line of code before you\u2019d documented it?\n\nDocumentation needs to have three main features:\n\n\n\tIt should have total coverage and document all the features of your project. Private methods should be documented for your developers, and public features need to be available to your users.\n\tIt should be consistent \u2013 a user should know what to expect from your documentation, and terminology should be accurate to your language.\n\tIt should be current \u2013 and that means staying accurate as new versions of your code base are released.\n\n\nBut you can also get these bonuses:\n\n\n\tAct as a suggested specification \u2013 a guide that will aid a developer in making something consistent and usable.\n\tIt can test your API quality.\n\tIt can enhance the communication skills within your development team.\n\n\nSo how do we get our documentation to be rich and full of features, instead of a little worn out like Boxing Day leftovers?\n\nWrite your documentation first\n\nWhen I say first, I mean first. Not after you\u2019ve started writing the code. Not even after you\u2019ve started writing your unit tests. First. You may or may not have been provided with a decent specification, but the first job should be to turn your requirements for a feature into documentation. \n\nIt works best when it takes the form of in-code comments. It works even better when your in-code comments take a standard documentation format that you can later use to generate published documentation for your users. This has the benefit of immediately making your docs as version controlled as your code-base, and it saves having to rewrite, copy or otherwise harass your docs into something legible later on. \n\nAlmost all languages have a self-documentation format these days. My choice of format for JavaScript is JSDocToolkit, and the sort of things I look for are the ability to specify private and public methods, full options object statements (opts as Opts only is a no-no), and the ability to include good examples.\n\nSo, our example for today will be a new festive feature for a JavaScript API. We\u2019ve been asked to specify a sled for Santa to get around the world to give out toys:\n\n\n\tSanta needs to be able to travel around the world in one night to deliver toys to children, and he\u2019ll need some reindeer to pull his sled.\n\n\nAs documentation, it would look like:\n\n/**\n@name Sled\n@extends Vehicle\n@constructor\n@description Create a new sled to send Santa around the world to deliver toys to good kids.\n\t@param {Object} [opts] Options\n\t@param {number} [opts.capacity='50'] Set the capacity of the sled\n\t@param {string} [opts.pilot='santa'] The pilot of the sled.\n@example\n\t// Create a sled and specify some reindeer.\n\tnew Sled().reindeer(['Dasher', 'Dancer', 'Prancer', 'Vixen', 'Comet', 'Cupid']);\n*/\n\nBy breaking it down as documentation, you can, for example, hand this over to another developer without the need to explain the feature in much depth, and they\u2019ll develop something that has to match this piece of documentation. It specifies everything that is important to this feature \u2013 its default values and types, and where it inherits other features from. \n\nWe know that we need to specify some way of setting reindeer to pull the sled and also some toys to give, and so we can quickly specify extra methods for the sled:\n\n/*\n@name vehicle.Sled#reindeer\n@function\n@description Set the reindeer that will pull Santa's sled.\n\t@param {string[]} reindeer A list of the reindeer.\n@example\n\t// specifying some reindeer\n\tSled().reindeer(['Dasher', 'Dancer', 'Rudolph', 'Vixen']);\n*/\n/*\n@name vehicle.Sled#toys\n@function\n@description Add a list of toys and recipients to the Sled.\n\t@param {Object[]} toys A list of toys and who will receive them.\n@example\n\t// Adding toys to the sled\n\tSled().toys([\n\t\t{name:'Brian', toy:'Fire Engine'},\n\t\t{name:'Drew', toy:'Roller-skates'},\n\t\t{name:'Anna', toy:'Play-doh'},\n\t\t...\n\t\t]);\n*/\n\nJob done! You\u2019ve got a specification to share with your team and something useful for your users in the form of full examples, and you didn\u2019t even have to open another text editor.\n\nUse your documentation to share knowledge\n\nDocumentation isn\u2019t just for users. It\u2019s also used by internal developers to explain what they\u2019ve written and how it works. This is especially valuable where the team is large or the code-base sprawling.\n\nSo, returning to our example, the next step would be to share with the rest of the team (or at least a selection of the team if yours is large) what the documentation looks like. This is useful for two main reasons:\n\n\n\tThey can see if they understand what the documentation says the feature will do. It\u2019s best if they haven\u2019t seen the requirement before. If your fellow developers can\u2019t work out what \u2018MagicMethodX\u2019 is going to return from the docs, neither can your users.\n\tThey can check that the feature accomplishes everything that they expect to, and that it\u2019s consistent with the rest of the functionality.\n\n\nOn previous projects, we\u2019ve taken to referring to this stage of the development process as the \u2018bun fight\u2019. It\u2019s a chance for everyone to have an honest say and throw a few pies without actually causing anyone to have to rewrite any code. If you can identify at this stage that a feature is over-complicated, lacking or just plain useless, you\u2019ll all be much happier to throw out a few lines of documentation than you may have been to throw out a partial, or even complete, piece of functionality.\n\nDocumentation has your back\n\nThe final benefit to working in this way is that your documentation not only remains accurate, it\u2019s always as accurate as your latest release. It can\u2019t fall behind.

{"rowid": 225, "title": "Good Ideas Grow on Paper", "contents": "Great designers have one thing in common: their design process is centred on ideas; ideas that are more often than not developed on paper. Though it\u2019s often tempting to take the path of least resistance, turning to the computer in the headlong rush to complete a project (often in the face of formidable client pressure), resist the urge and \u2013 for a truly great idea \u2013 start first on paper.\n\nThe path of least resistance is often characterised by clich\u00e9 and overused techniques \u2013 one per cent noise, border-radius, text-shadow \u2013 the usual suspects \u2013 techniques that are ten-a-penny at the gallery sites. Whilst all are useful, and technique and craft are important, great design isn\u2019t about technique alone \u2013 it\u2019s about technique in the service of good ideas.\n\nBut how do we generate those ideas?\n\nInspiration can certainly come to you out of the blue. When working as a designer in a role which often consists of incubating good ideas, however, idly waiting for the time-honoured lightbulb to appear above your head just isn\u2019t good enough. We need to establish an environment where we tip the odds of getting good ideas in our favour.\n\nSo, when faced with the blank canvas, what do we do to unlock the proverbial tidal wave of creativity? Fear not. We\u2019re about to share with you a couple of stalwart techniques that will stand you in good stead when you need that good idea, in the face of the pressure of yet another looming deadline.\n\nGet the process right\n\nWhere do ideas come from? In many cases they come from anywhere but the screen. Hence, our first commandment is to close the lid of your computer and, for a change, work on paper. It might seem strange, it might also seem like a distraction, but \u2013 trust us \u2013 the time invested here will more than pay off.\n\nIdea generation should be a process of rapid iteration, sketching and thinking aloud, all processes best undertaken in more fast paced, analogue media. Our tool of choice is the Sharpie and Flip Chart Combo\u00a9, intentionally low resolution to encourage lo-fi idea generation. In short, your tools should be designed not to be precious, but to quickly process your thoughts. Ideas can be expressed with a thick line marker or by drawing with a stick in the sand; it\u2019s the ideas that matter, not the medium.\n\nInput\u2009>\u2009Synthesise\u2009>\u2009Output\n\nIdeas don\u2019t materialise in a vacuum. Without constant input, the outputs will inevitably remain the same. As such, it\u2019s essential to maintain an inquisitive mind, ensuring a steady flow of new triggers and stimuli that enable your thinking to evolve.\n\nWhat every designer brings to the table is their prior experience and unique knowledge. It should come as no surprise to discover that a tried and tested method of increasing that knowledge is, believe it or not, to read \u2013 often and widely. The best and most nuanced ideas come after many years of priming the brain with an array of diverse material, a point made recently in Jessica Hische\u2019s aptly named Why You Should Know Your Shit.\n\nOne of the best ways of synthesising the knowledge you accumulate is to write. The act of writing facilitates your thinking and stores the pieces of the jigsaw you\u2019ll one day return to. You don\u2019t have to write a book or a well-articulated article; a scribbled note in the margin will suffice in facilitating the process of digestion.\n\nAs with writing, we implore you to make sketching an essential part of your digestion process. More immediate than writing, sketching has the power to put yet unformed ideas down on paper, giving you an insight into the fantastic conceptions you\u2019re more often than not still incubating.\n\nOur second commandment is a practical one: always carry a sketchbook and a pen. Although it seems that the very best ideas are scribbled on the back of a beer mat or a wine-stained napkin, always carrying your \u2018thinking utensils\u2019 should be as natural as not leaving the house without your phone, wallet, keys or pants.\n\nFurther, the more you use your sketchbook, the less precious you\u2019ll find yourself becoming. Sketching isn\u2019t about being an excellent draughtsman, it\u2019s about synthesising and processing your thoughts and ideas, as Jason Santa Maria summarises nicely in his article Pretty Sketchy:\n\n\n\tSketchbooks are not about being a good artist, they\u2019re about being a good thinker.\n\n\tJason Santa Maria\n\n\nThe sketchbook and pen should become your trusted tools in your task to constantly survey the world around you. As Paul Smith says, You Can Find Inspiration in Anything; close the lid, look beyond the computer; there\u2019s a whole world of inspiration out there.\n\nLearn to love old dusty buildings\n\nSo, how do you learn? How do you push beyond the predictable world pre-filtered by Mr Google? The answer lies in establishing a habit of exploring the wonderful worlds of museums and libraries, dusty old buildings that repay repeated visits.\n\nOnce the primary repositories of thought and endless sources of inspiration, these institutions are now often passed over for the quick fix of a Google search or Wikipedia by you, the designer, chained to a desk and manacled to a MacBook. Whilst others might frown, we urge you to get away from your desk and take an eye-opening stroll through the knowledge-filled corridors of yore (and don\u2019t forget to bring your sketchbook).\n\nHere you\u2019ll find ideas aplenty, ideas that will set you apart from your peers, who remain ever-reliant on the same old digital sources.\n\nThe idea generation toolbox\n\nNow that we\u2019ve established the importance of getting the process and the context right, it\u2019s time to meet the idea generation toolbox: a series of tools and techniques that can be applied singularly or in combination to solve the perennial problem of the blank canvas.\n\nThe clean sheet of paper, numbing in its emptiness, can prove an insurmountable barrier to many a project, but the route beyond it involves just a few, well-considered steps. The route to a good idea lies in widening your pool of inspiration at the project outset. Let go and generate ideas quickly; it\u2019s critical to diverge before you converge \u2013 but how do we do this and what exactly do we mean by this?\n\nThe temptation is to pull something out of your well-worn box of tricks, something that you know from experience will do the job. We urge you, however, not to fall prey to this desire. You can do better; better still, a few of you putting your minds together can do a lot better. By avoiding the path of least resistance, you can create something extraordinary.\n\nCulturally, we value logical, linear thinking. Since the days of Plato and Aristotle, critical thinking, deduction and the pursuit of truth have been rewarded. To generate creative ideas, however, we need to start thinking sideways, making connections that don\u2019t necessarily follow logically. Lateral thinking, a phrase coined by Edward de Bono in 1967, aptly describes this very process:\n\n\n\tWith logic you start out with certain ingredients, just as in playing chess you start out with given pieces \u2013 lateral thinking is concerned not with playing with the existing pieces but with seeking to change those very pieces.\n\n\tEdward de Bono\n\n\nOne of the easiest ways to start thinking laterally is to start with a mind map, a perfect tool for widening the scope of a project beyond the predictable and an ideal one for getting the context right for discovery.\n\nMaking connections\n\nMind maps can be used to generate, visualise and structure ideas. Arranged intuitively and classified around groupings, mind maps allow chance connections to be drawn across related groups of information, and are perfect for exposing alogical associations and unexpected relationships.\n\nGet a number of people together in a room, equipped with the Sharpie and Flip Chart Combo\u00a9. Give yourself a limited amount of time \u2013 half an hour should prove more than enough \u2013 and you\u2019ll be surprised at the results a few well-chosen people can generate in a very short space of time. The key is to work fast, diverge and not inhibit thinking. \n\nWe\u2019ve been embracing Tony Buzan\u2019s methods in our teaching for over a decade. His ideas on the power of radiant thinking and how this can be applied to mind maps, uncover the real power which lies in the human brain\u2019s ability to spot connections across a mapped out body of diverse knowledge.\n\nFrank Chimero wrote about this recently in How to Have an Idea, which beautifully illustrates Mr Buzan\u2019s theories, articulating the importance of the brain\u2019s ability to make abstract connections, finding unexpected pairings when a concept is mapped out on paper.\n\nOnce a topic is surveyed and a rich set of stimuli articulated, the next stage is to draw connections, pulling from opposite sides of the mind map. It\u2019s at this point, when defining alogical connections, that the truly interesting and unexpected ideas are often uncovered.\n\nThe curve ball\n\nIf you\u2019ve followed our instructions so far, all being well, you should have a number of ideas. Good news: we have one last technique to throw into the mix. We like to call it \u2018the curve ball\u2019, that last minute \u2018something\u2019 that forces you to rethink and encourages you to address a problem from a different direction.\n\nThere are a number of ways of throwing in a curve ball \u2013 a short, sharp, unexpected impetus \u2013 but we have a firm favourite we think you\u2019ll appreciate. Brian Eno and Peter Schmidt\u2019s Oblique Strategies \u2013 subtitled \u2018Over One Hundred Worthwhile Dilemmas\u2019 \u2013 are the perfect creative tool for throwing in a spot of unpredictability. As Eno and Schmidt put it:\n\n\n\tThe Oblique Strategies can be used as a pack (a set of possibilities being continuously reviewed in the mind) or by drawing a single card from the shuffled pack when a dilemma occurs in a working situation. In this case the card is trusted even if its appropriateness is quite unclear. They are not final, as new ideas will present themselves, and others will become self-evident.\n\n\tBrian Eno and Peter Schmidt\n\n\nSimply pick a card and apply the strategy to the problem at hand. The key here, as with de Bono\u2019s techniques, is to embrace randomness and provocation to inspire lateral creative approaches.\n\nTo assist this process, you might wish to consult one of the many virtual decks of Oblique Strategies online.\n\nWrapping up\n\nTo summarise, it\u2019s tempting to see the route to the fastest satisfactory conclusion in a computer when, in reality, that\u2019s the last place you should start. The tools we\u2019ve introduced, far from time-consuming, are hyper-efficient, always at hand and, if you factor them into your workflow, the key to unlocking the ideas that set the great designers apart.\n\nWe wish you well on your quest in search of the perfect idea, now armed with the knowledge that the quest begins on paper.", "year": "2010", "author": "The Standardistas", "author_slug": "thestandardistas", "published": "2010-12-13T00:00:00+00:00", "url": "https://24ways.org/2010/good-ideas-grow-on-paper/", "topic": "process"}
{"rowid": 233, "title": "Wrapping Things Nicely with HTML5 Local Storage", "contents": "HTML5 is here to turn the web from a web of hacks into a web of applications \u2013 and we are well on the way to this goal. The coming year will be totally and utterly awesome if you are excited about web technologies.\n\nThis year the HTML5 revolution started and there is no stopping it. For the first time all the browser vendors are rallying together to make a technology work. The new browser war is fought over implementation of the HTML5 standard and not over random additions. We live in exciting times.\n\nStarting with a bang\n\nAs with every revolution there is a lot of noise with bangs and explosions, and that\u2019s the stage we\u2019re at right now. HTML5 showcases are often CSS3 showcases, web font playgrounds, or video and canvas examples.\n\nThis is great, as it gets people excited and it gives the media something to show. There is much more to HTML5, though. Let\u2019s take a look at one of the less sexy, but amazingly useful features of HTML5 (it was in the HTML5 specs, but grew at such an alarming rate that it warranted its own spec): storing information on the client-side.\n\nWhy store data on the client-side?\n\nStoring information in people\u2019s browsers affords us a few options that every application should have:\n\n\n\tYou can retain the state of an application \u2013 when the user comes back after closing the browser, everything will be as she left it. That\u2019s how \u2018real\u2019 applications work and this is how the web ones should, too.\n\tYou can cache data \u2013 if something doesn\u2019t change then there is no point in loading it over the Internet if local access is so much faster\n\tYou can store user preferences \u2013 without needing to keep that data on your server at all.\n\n\nIn the past, storing local data wasn\u2019t much fun.\n\nThe pain of hacky browser solutions\n\nIn the past, all we had were cookies. I don\u2019t mean the yummy things you get with your coffee, endorsed by the blue, furry junkie in Sesame Street, but the other, digital ones. Cookies suck \u2013 it isn\u2019t fun to have an unencrypted HTTP overhead on every server request for storing four kilobytes of data in a cryptic format. It was OK for 1994, but really neither an easy nor a beautiful solution for the task of storing data on the client.\n\nThen came a plethora of solutions by different vendors \u2013 from Microsoft\u2019s userdata to Flash\u2019s LSO, and from Silverlight isolated storage to Google\u2019s Gears. If you want to know just how many crazy and convoluted ways there are to store a bit of information, check out Samy\u2019s evercookie.\n\nClearly, we needed an easier and standardised way of storing local data.\n\nKeeping it simple \u2013 local storage\n\nAnd, lo and behold, we have one. The local storage API (or session storage, with the only difference being that session data is lost when the window is closed) is ridiculously easy to use. All you do is call a few methods on the window.localStorage object \u2013 or even just set the properties directly using the square bracket notation:\n\nif('localStorage' in window && window['localStorage'] !== null){\n\tvar store = window.localStorage;\n\n\t// valid, API way\n\t\tstore.setItem(\u2018cow\u2019,\u2018moo\u2019);\n\t\tconsole.log(\n\t\tstore.getItem(\u2018cow\u2019)\n\t); // => \u2018moo\u2019\n\n\t// shorthand, breaks at keys with spaces\n\t\tstore.sheep = \u2018baa\u2019 \n\t\tconsole.log(\n\t\tstore.sheep \n\t); // \u2018baa\u2019\n\n\t// shorthand for all\n\t\tstore[\u2018dog\u2019] = \u2018bark\u2019\n\t\tconsole.log(\n\t\tstore[\u2018dog\u2019]\n\t); // => \u2018bark\u2019\n\n}\n\nBrowser support is actually pretty good: Chrome 4+; Firefox 3.5+; IE8+; Opera 10.5+; Safari 4+; plus iPhone 2.0+; and Android 2.0+. That should cover most of your needs. Of course, you should check for support first (or use a wrapper library like YUI Storage Utility or YUI Storage Lite).\n\nThe data is stored on a per domain basis and you can store up to five megabytes of data in localStorage for each domain.\n\nStrings attached\n\nBy default, localStorage only supports strings as storage formats. You can\u2019t store results of JavaScript computations that are arrays or objects, and every number is stored as a string. This means that long, floating point numbers eat into the available memory much more quickly than if they were stored as numbers.\n\nvar cowdesc = \"the cow is of the bovine ilk, \"+\n\t\t\"one end is for the moo, the \"+\n\t\t\"other for the milk\";\n\nvar cowdef = {\n\tilk\u201cbovine\u201d,\n\tlegs,\n\tudders,\n\tpurposes\n\t\tfront\u201cmoo\u201d,\n\t\tend\u201cmilk\u201d\n\t}\n};\n\nwindow.localStorage.setItem(\u2018describecow\u2019,cowdesc);\nconsole.log(\n\twindow.localStorage.getItem(\u2018describecow\u2019)\n); // => the cow is of the bovine\u2026 \n\nwindow.localStorage.setItem(\u2018definecow\u2019,cowdef);\nconsole.log(\n\twindow.localStorage.getItem(\u2018definecow\u2019)\n); // => [object Object] = bad!\n\nThis limits what you can store quite heavily, which is why it makes sense to use JSON to encode and decode the data you store:\n\nvar cowdef = {\n\t\"ilk\":\"bovine\",\n\t\"legs\":4,\n\t\"udders\":4,\n\t\"purposes\":{\n\t\"front\":\"moo\",\n\t\"end\":\"milk\"\n\t}\n};\n\nwindow.localStorage.setItem(\u2018describecow\u2019,JSON.stringify(cowdef));\nconsole.log(\n\tJSON.parse(\n\t\twindow.localStorage.getItem(\u2018describecow\u2019)\n\t)\n); // => Object { ilk=\u201cbovine\u201d, more\u2026}\n\nYou can also come up with your own formatting solutions like CSV, or pipe | or tilde ~ separated formats, but JSON is very terse and has native browser support.\n\nSome use case examples\n\nThe simplest use of localStorage is, of course, storing some data: the current state of a game; how far through a multi-form sign-up process a user is; and other things we traditionally stored in cookies. Using JSON, though, we can do cooler things.\n\nSpeeding up web service use and avoiding exceeding the quota\n\nA lot of web services only allow you a certain amount of hits per hour or day, and can be very slow. By using localStorage with a time stamp, you can cache results of web services locally and only access them after a certain time to refresh the data.\n\nI used this technique in my An Event Apart 10K entry, World Info, to only load the massive dataset of all the world information once, and allow for much faster subsequent visits to the site. The following screencast shows the difference:\n\n\n\nFor use with YQL (remember last year\u2019s 24 ways entry?), I\u2019ve built a small script called YQL localcache that wraps localStorage around the YQL data call. An example would be the following:\n\nyqlcache.get({\n\tyql: 'select * from flickr.photos.search where text=\"santa\"',\n\tid: 'myphotos',\n\tcacheage: ( 60*60*1000 ),\n\tcallback: function(data) {\n\t\tconsole.log(data);\n\t}\n});\n\nThis loads photos of Santa from Flickr and stores them for an hour in the key myphotos of localStorage. If you call the function at various times, you receive an object back with the YQL results in a data property and a type property which defines where the data came from \u2013 live is live data, cached means it comes from cache, and freshcache indicates that it was called for the first time and a new cache was primed. The cache will work for an hour (60\u00d760\u00d71,000 milliseconds) and then be refreshed. So, instead of hitting the YQL endpoint over and over again, you hit it once per hour.\n\nCaching a full interface\n\nAnother use case I found was to retain the state of a whole interface of an application by caching the innerHTML once it has been rendered. I use this in the Yahoo Firehose search interface, and you can get the full story about local storage and how it is used in this screencast:\n\n\n\nThe stripped down code is incredibly simple (JavaScript with PHP embed):\n\n// test for localStorage support\nif(('localStorage' in window) && window['localStorage'] !== null){\n\nvar f = document.getElementById(\u2018mainform\u2019);\n// test with PHP if the form was sent (the submit button has the name \u201csent\u201d)\n\n\n\t// get the HTML of the form and cache it in the property \u201cstate\u201d\n\tlocalStorage.setItem(\u2018state\u2019,f.innerHTML);\n\n// if the form hasn\u2019t been sent\u2026\n\n\n\t// check if a state property exists and write back the HTML cache\n\tif(\u2018state\u2019 in localStorage){\n\t\tf.innerHTML = localStorage.getItem(\u2018state\u2019); \n\t}\n\n\t\n\n}\n\nOther ideas\n\nIn essence, you can use local storage every time you need to speed up access. For example, you could store image sprites in base-64 encoded datasets instead of loading them from a server. Or you could store CSS and JavaScript libraries on the client. Anything goes \u2013 have a play.\n\nIssues with local and session storage\n\nOf course, not all is rainbows and unicorns with the localStorage API. There are a few niggles that need ironing out. As with anything, this needs people to use the technology and raise issues. Here are some of the problems:\n\n\n\tInadequate information about storage quota \u2013 if you try to add more content to an already full store, you get a QUOTA_EXCEEDED_ERR and that\u2019s it. There\u2019s a great explanation and test suite for localStorage quota available.\n\tLack of automatically expiring storage \u2013 a feature that cookies came with. Pamela Fox has a solution (also available as a demo and source code)\n\tLack of encrypted storage \u2013 right now, everything is stored in readable strings in the browser.\n\n\nBigger, better, faster, more!\n\nAs cool as the local and session storage APIs are, they are not quite ready for extensive adoption \u2013 the storage limits might get in your way, and if you really want to go to town with accessing, filtering and sorting data, real databases are what you\u2019ll need. And, as we live in a world of client-side development, people are moving from heavy server-side databases like MySQL to NoSQL environments.\n\nOn the web, there is also a lot of work going on, with Ian Hickson of Google proposing the Web SQL database, and Nikunj Mehta, Jonas Sicking (Mozilla), Eliot Graff (Microsoft) and Andrei Popescu (Google) taking the idea beyond simply replicating MySQL and instead offering Indexed DB as an even faster alternative.\n\nOn the mobile front, a really important feature is to be able to store data to use when you are offline (mobile coverage and roaming data plans anybody?) and you can use the Offline Webapps API for that.\n\nAs I mentioned at the beginning, we have a very exciting time ahead \u2013 let\u2019s make this web work faster and more reliably by using what browsers offer us.

{"rowid": 238, "title": "Everything You Wanted To Know About Gradients (And a Few Things You Didn\u2019t)", "contents": "Hello. I am here to discuss CSS3 gradients. Because, let\u2019s face it, what the web really needed was more gradients.\n\nStill, despite their widespread use (or is it overuse?), the smartly applied gradient can be a valuable contributor to a designer\u2019s vocabulary. There\u2019s always been a tension between the inherently two-dimensional nature of our medium, and our desire for more intensity, more depth in our designs. And a gradient can evoke so much: the splay of light across your desk, the slow decrease in volume toward the end of your favorite song, the sunset after a long day. When properly applied, graded colors bring a much needed softness to our work.\n\nOf course, that whole \u2018proper application\u2019 thing is the tricky bit.\n\nBut given their place in our toolkit and their prominence online, it really is heartening to see we can create gradients directly with CSS. They\u2019re part of the draft images module, and implemented in two of the major rendering engines.\n\nStill, I\u2019ve always found CSS gradients to be one of the more confusing aspects of CSS3. So if you\u2019ll indulge me, let\u2019s take a quick look at how to create CSS gradients\u2014hopefully we can make them seem a bit more accessible, and bring a bit more art into the browser.\n\nGradient theory 101 (I hope that\u2019s not really a thing)\n\nRight. So before we dive into the code, let\u2019s cover a few basics. Every gradient, no matter how complex, shares a few common characteristics. Here\u2019s a straightforward one:\n\n I spent seconds hours designing this gradient. I hope you like it.\n\nAt either end of our image, we have a final color value, or color stop: on the left, our stop is white; on the right, black. And more color-rich gradients are no different:\n\n (Don\u2019t ever really do this. Please. I beg you.)\n\nIt\u2019s visually more intricate, sure. But at the heart of it, we have just seven color stops (red, orange, yellow, and so on), making for a fantastic gradient all the way.\n\nNow, color stops alone do not a gradient make. Between each is a transition point, the fail-over point between the two stops. Now, the transition point doesn\u2019t need to fall exactly between stops: it can be brought closer to one stop or the other, influencing the overall shape of the gradient.\n\nA tale of two syntaxes\n\nArmed with our new vocabulary, let\u2019s look at a CSS gradient in the wild. Behold, the simple input button:\n\n\n\nThere\u2019s a simple linear gradient applied vertically across the button, moving from a bright sunflowerish hue (#FAA51A, for you hex nuts in the audience) to a much richer orange (#F47A20). And here\u2019s the CSS that makes it happen:\n\ninput[type=submit] {\n\tbackground-color: #F47A20;\n\tbackground-image: -moz-linear-gradient(\n\t\t#FAA51A,\n\t\t#F47A20\n\t\t);\n\tbackground-image: -webkit-gradient(linear, 0 0, 0 100%,\n\t\tcolor-stop(0, #FAA51A),\n\t\tcolor-stop(1, #F47A20)\n\t\t);\n}\n\nI\u2019ve borrowed David DeSandro\u2019s most excellent formatting suggestions for gradients to make this snippet a bit more legible but, still, the code above might have turned your stomach a bit. And that\u2019s perfectly understandable\u2014heck, it sort of turned mine. But let\u2019s step through the CSS slowly, and see if we can\u2019t make it a little less terrifying.\n\nVerbose WebKit is verbose\n\nHere\u2019s the syntax for our little gradient on WebKit:\n\nbackground-image: -webkit-gradient(linear, 0 0, 0 100%,\n\tcolor-stop(0, #FAA51A),\n\tcolor-stop(1, #F47A20)\n\t);\n\nWoof. Quite a mouthful, no? Well, here\u2019s what we\u2019re looking at:\n\n\n\tWebKit has a single -webkit-gradient property, which can be used to create either linear or radial gradients.\n\tThe next two values are the starting and ending positions for our gradient (0 0 and 0 100%, respectively). Linear gradients are simply drawn along the path between those two points, which allows us to change the direction of our gradient simply by altering its start and end points.\n\tAfterward, we specify our color stops with the oh-so-aptly named color-stop parameter, which takes the stop\u2019s position on the gradient (0 being the beginning, and 100% or 1 being the end) and the color itself.\n\n\nFor a simple two-color gradient like this, -webkit-gradient has a bit of shorthand notation to offer us:\n\nbackground-image: -webkit-gradient(linear, 0 0, 0 100%,\n\tfrom(#FAA51A),\n\tto(#FAA51A)\n\t);\n\nfrom(#FAA51A) is equivalent to writing color-stop(0, #FAA51A), and to(#FAA51A) is the same as color-stop(1, #FAA51A) or color-stop(100%, #FAA51A)\u2014in both cases, we\u2019re simply declaring the first and last color stops in our gradient.\n\nTerse Gecko is terse\n\nWebKit proposed its syntax back in 2008, heavily inspired by the way gradients are drawn in the canvas specification. However, a different, leaner syntax came to the fore, eventually appearing in a draft module specification in CSS3.\n\nNaturally, because nothing on the web was meant to be easy, this is the one that Mozilla has implemented.\n\nHere\u2019s how we get gradient-y in Gecko:\n\nbackground-image: -moz-linear-gradient(\n\t#FAA51A,\n\t#F47A20\n\t);\n\nWait, what? Done already? That\u2019s right. By default, -moz-linear-gradient assumes you\u2019re trying to create a vertical gradient, starting from the top of your element and moving to the bottom. And, if that\u2019s the case, then you simply need to specify your color stops, delimited with a few commas.\n\nI know: that was almost\u2026 painless. But the W3C/Mozilla syntax also affords us a fair amount of flexibility and control, by introducing features as we need them.\n\nWe can specify an origin point for our gradient:\n\nbackground-image: -moz-linear-gradient(50% 100%,\n\t#FAA51A,\n\t#F47A20\n\t);\n\nAs well as an angle, to give it a direction:\n\nbackground-image: -moz-linear-gradient(50% 100%, 45deg,\n\t#FAA51A,\n\t#F47A20\n\t);\n\nAnd we can specify multiple stops, simply by adding to our comma-delimited list:\n\nbackground-image: -moz-linear-gradient(50% 100%, 45deg,\n\t#FAA51A,\n\t#FCC,\n\t#F47A20\n\t);\n\nBy adding a percentage after a given color value, we can determine its position along the gradient path:\n\nbackground-image: -moz-linear-gradient(50% 100%, 45deg,\n\t#FAA51A,\n\t#FCC 20%,\n\t#F47A20\n\t);\n\nSo that\u2019s some of the flexibility implicit in the W3C/Mozilla-style syntax.\n\nNow, I should note that both syntaxes have their respective fans. I will say that the W3C/Mozilla-style syntax makes much more sense to me, and lines up with how I think about creating gradients. But I can totally understand why some might prefer WebKit\u2019s more verbose approach to the, well, looseness behind the -moz syntax. \u00c0 chacun son gradient syntax.\n\nStill, as the language gets refined by the W3C, I really hope some consensus is reached by the browser vendors. And with Opera signaling that it will support the W3C syntax, I suppose it falls on WebKit to do the same.\n\nReusing color stops for fun and profit\n\nBut CSS gradients aren\u2019t all simple colors and shapes and whatnot: by getting inventive with individual color stops, you can create some really complex, compelling effects.\n\nTim Van Damme, whose brain, I believe, should be posthumously donated to science, has a particularly clever application of gradients on The Box, a site dedicated to his occasional podcast series. Now, there are a fair number of gradients applied throughout the UI, but it\u2019s the feature image that really catches the eye.\n\nYou see, there\u2019s nothing that says you can\u2019t reuse color stops. And Tim\u2019s exploited that perfectly.\n\nHe\u2019s created a linear gradient, angled at forty-five degrees from the top left corner of the photo, starting with a fully transparent white (rgba(255, 255, 255, 0)). At the halfway mark, he\u2019s established another color stop at an only slightly more opaque white (rgba(255, 255, 255, 0.1)), making for that incredibly gradual brightening toward the middle of the photo.\n\n\n\nBut then he has set another color stop immediately on top of it, bringing it back down to rgba(255, 255, 255, 0) again. This creates that fantastically hard edge that diagonally bisects the photo, giving the image that subtle gloss.\n\n\n\nAnd his final color stop ends at the same fully transparent white, completing the effect. Hot? I do believe so.\n\nRocking the radials\n\nWe\u2019ve been looking at linear gradients pretty exclusively. But I\u2019d be remiss if I didn\u2019t at least mention radial gradients as a viable option, including a modest one as a link accent on a navigation bar:\n\n\n\nAnd here\u2019s the relevant CSS:\n\nbackground: -moz-radial-gradient(50% 100%, farthest-side,\n\trgb(204, 255, 255) 1%,\n\trgb(85, 85, 85) 15%,\n\trgba(85, 85, 85, 0)\n\t);\nbackground: -webkit-gradient(radial, 50% 100%, 0, 50% 100%, 15,\n\tfrom(rgb(204, 255, 255)),\n\tto(rgba(85, 85, 85, 0))\n\t);\n\nNow, the syntax builds on what we\u2019ve already learned about linear gradients, so much of it might be familiar to you, picking out color stops and transition points, as well as the two syntaxes\u2019 reliance on either a separate property (-moz-radial-gradient) or parameter (-webkit-gradient(radial, \u2026)) to shift into circular mode.\n\nMozilla introduces another stand-alone property (-moz-radial-gradient), and accepts a starting point (50% 100%) from which the circle radiates. There\u2019s also a size constant defined (farthest-side), which determines the reach and shape of our gradient.\n\nWebKit is again the more verbose of the two syntaxes, requiring both starting and ending points (50% 100% in both cases). Each also accepts a radius in pixels, allowing you to control the skew and breadth of the circle.\n\nAgain, this is a fairly modest little radial gradient. Time and article length (and, let\u2019s be honest, your author\u2019s completely inadequate grasp of geometry) prevent me from covering radial gradients in much more detail, because they are incredibly powerful. For those interested in learning more, I can\u2019t recommend the references at Mozilla and Apple strongly enough.\n\nLeave no browser behind\n\nBut no matter the kind of gradients you\u2019re working with, there is a large swathe of browsers that simply don\u2019t support gradients. Thankfully, it\u2019s fairly easy to declare a sensible fallback\u2014it just depends on the kind of fallback you\u2019d like. Essentially, gradient-blind browsers will disregard any properties containing references to either -moz-linear-gradient, -moz-radial-gradient, or -webkit-gradient, so you simply need to keep your fallback isolated from those properties.\n\nFor example: if you\u2019d like to fall back to a flat color, simply declare a separate background-color:\n\n.nav {\n\tbackground-color: #000;\n\tbackground-image: -moz-linear-gradient(rgba(0, 0, 0, 0), rgba(255, 255, 255, 0.45));\n\tbackground-image: -webkit-gradient(linear, 0 0, 0 100%, from(rgba(0, 0, 0, 0)), to(rgba(255, 255, 255, 0.45)));\n}\n\nOr perhaps just create three separate background properties.\n\n.nav {\n\tbackground: #000;\n\tbackground: #000 -moz-linear-gradient(rgba(0, 0, 0, 0), rgba(255, 255, 255, 0.45));\n\tbackground: #000 -webkit-gradient(linear, 0 0, 0 100%, from(rgba(0, 0, 0, 0)), to(rgba(255, 255, 255, 0.45)));\n}\n\nWe can even build on this to fall back to a non-gradient image:\n\n.nav {\n\tbackground: #000 url(\"faux-gradient-lol.png\") repeat-x;\n\tbackground: #000 -moz-linear-gradient(rgba(0, 0, 0, 0), rgba(255, 255, 255, 0.45));\n\tbackground: #000 -webkit-gradient(linear, 0 0, 0 100%, from(rgba(0, 0, 0, 0)), to(rgba(255, 255, 255, 0.45)));\n}\n\nNo matter the approach you feel most appropriate to your design, it\u2019s really just a matter of keeping your fallback design quarantined from its CSS3-ified siblings.\n\n(If you\u2019re feeling especially masochistic, there\u2019s even a way to get simple linear gradients working in IE via Microsoft\u2019s proprietary filters. Of course, those come with considerable performance penalties that even Microsoft is quick to point out, so I\u2019d recommend avoiding those.\n\nAnd don\u2019t tell Andy Clarke I told you, or he\u2019ll probably unload his Derringer at me. Or something.)\n\nGo forth and, um, gradientify!\n\nIt\u2019s entirely possible your head\u2019s spinning. Heck, mine is, but that might be the effects of the \u2019nog. But maybe you\u2019re wondering why you should care about CSS gradients. After all, images are here right now, and work just fine. \n\nWell, there are some quick benefits that spring to mind: fewer HTTP requests are needed; CSS3 gradients are easily made scalable, making them ideal for variable widths and heights; and finally, they\u2019re easily modifiable by tweaking a few CSS properties. Because, let\u2019s face it, less time spent yelling at Photoshop is a very, very good thing.\n\nOf course, CSS-generated gradients are not without their drawbacks. The syntax can be confusing, and it\u2019s still under development at the W3C. As we\u2019ve seen, browser support is still very much in flux. And it\u2019s possible that gradients themselves have some real performance drawbacks\u2014so test thoroughly, and gradient carefully.\n\nBut still, as syntaxes converge, and support improves, I think generated gradients can make a compelling tool in our collective belts. The tasteful design is, of course, entirely up to you.\n\nSo have fun, and get gradientin\u2019.", "year": "2010", "author": "Ethan Marcotte", "author_slug": "ethanmarcotte", "published": "2010-12-22T00:00:00+00:00", "url": "https://24ways.org/2010/everything-you-wanted-to-know-about-gradients/", "topic": "code"}
{"rowid": 240, "title": "My CSS Wish List", "contents": "I love Christmas. I love walking around the streets of London, looking at the beautifully decorated windows, seeing the shiny lights that hang above Oxford Street and listening to Christmas songs.\n\nI\u2019m not going to lie though. Not only do I like buying presents, I love receiving them too. I remember making long lists that I would send to Father Christmas with all of the Lego sets I wanted to get. I knew I could only get one a year, but I would spend days writing the perfect list.\n\nThe years have gone by, but I still enjoy making wish lists. And I\u2019ll tell you a little secret: my mum still asks me to send her my Christmas list every year.\n\nThis time I\u2019ve made my CSS wish list. As before, I\u2019d be happy with just one present.\n\nBefore I begin\u2026\n\n\u2026 this list includes:\n\n\n\tthings that don\u2019t exist in the CSS specification (if they do, please let me know in the comments \u2013 I may have missed them);\n\tothers that are in the spec, but it\u2019s incomplete or lacks use cases and examples (which usually means that properties haven\u2019t been implemented by even the most recent browsers).\n\n\nLike with any other wish list, the further down I go, the more unrealistic my expectations \u2013 but that doesn\u2019t mean I can\u2019t wish. Some of the things we wouldn\u2019t have thought possible a few years ago have been implemented and our wishes fulfilled (think multiple backgrounds, gradients and transformations, for example).\n\nThe list\n\nCross-browser implementation of font-size-adjust\n\nWhen one of the fall-back fonts from your font stack is used, rather than the preferred (first) one, you can retain the aspect ratio by using this very useful property. It is incredibly helpful when the fall-back fonts are smaller or larger than the initial one, which can make layouts look less polished.\n\nWhat font-size-adjust does is divide the original font-size of the fall-back fonts by the font-size-adjust value. This preserves the x-height of the preferred font in the fall-back fonts. Here\u2019s a simple example:\n\np {\n font-family: Calibri, \"Lucida Sans\", Verdana, sans-serif;\n font-size-adjust: 0.47;\n}\n\nIn this case, if the user doesn\u2019t have Calibri installed, both Lucida Sans and Verdana will keep Calibri\u2019s aspect ratio, based on the font\u2019s x-height. This property is a personal favourite and one I keep pointing to.\n\nFirefox supported this property from version three. So far, it\u2019s the only browser that does. Fontdeck provides the font-size-adjust value along with its fonts, and has a handy tool for calculating it.\n\nMore control over overflowing text\n\nThe text-overflow property lets you control text that overflows its container. The most common use for it is to show an ellipsis to indicate that there is more text than what is shown. To be able to use it, the container should have overflow set to something other than visible, and white-space: nowrap:\n\ndiv {\n white-space: nowrap;\n width: 100%;\n overflow: hidden;\n text-overflow: ellipsis;\n}\n\nThis, however, only works for blocks of text on a single line. In the wish list of many CSS authors (and in mine) is a way of defining text-overflow: ellipsis on a block of multiple text lines. Opera has taken the first step and added support for the -o-ellipsis-lastline property, which can be used instead of ellipsis. This property is not part of the CSS3 spec, but we could certainly make good use of it if it were\u2026\n\nWebKit has -webkit-line-clamp to specify how many lines to show before cutting with an ellipsis, but support is patchy at best and there is no control over where the ellipsis shows in the text. Many people have spent time wrangling JavaScript to do this for us, but the methods used are very processor intensive, and introduce a JavaScript dependency.\n\nIndentation and hanging punctuation properties\n\nYou might notice a trend here: almost half of the items in this list relate to typography. The lack of fine-grained control over typographical detail is a general concern among designers and CSS authors. Indentation and hanging punctuation fall into this category.\n\nThe CSS3 specification introduces two new possible values for the text-indent property: each-line; and hanging. each-line would indent the first line of the block container and each line after a forced line break; hanging would invert which lines are affected by the indentation.\n\nThe proposed hanging-punctuation property would allow us to specify whether opening and closing brackets and quotes should hang outside the edge of the first and last lines. The specification is still incomplete, though, and asks for more examples and use cases.\n\nText alignment and hyphenation properties\n\nFollowing the typographic trend of this list, I\u2019d like to add better control over text alignment and hyphenation properties. The CSS3 module on Generated Content for Paged Media already specifies five new hyphenation-related properties (namely: hyphenate-dictionary; hyphenate-before and hyphenate-after; hyphenate-lines; and hyphenate-character), but it is still being developed and lacks examples.\n\nIn the text alignment realm, the new text-align-last property allows you to define how the last line of a block (or a line just before a forced break) is aligned, if your text is set to justify. Its value can be: start; end; left; right; center; and justify. The text-justify property should also allow you to have more control over text set to text-align: justify but, for now, only Internet Explorer supports this.\n\ncalc()\n\nThis is probably my favourite item in the list: the calc() function. This function is part of the CSS3 Values and Units module, but it has only been implemented by Firefox (4.0). To take advantage of it now you need to use the Mozilla vendor code, -moz-calc().\n\nImagine you have a fluid two-column layout where the sidebar column has a fixed width of 240 pixels, and the main content area fills the rest of the width available. This is how you could create that using -moz-calc():\n\n#main {\n width: -moz-calc(100% - 240px);\n}\n\nCan you imagine how many hacks and headaches we could avoid were this function available in more browsers? Transitions and animations are really nice and lovely but, for me, it\u2019s the ability to do the things that calc() allows you to that deserves the spotlight and to be pushed for implementation.\n\nSelector grouping with -moz-any()\n\nThe -moz-any() selector grouping has been introduced by Mozilla but it\u2019s not part of any CSS specification (yet?); it\u2019s currently only available on Firefox 4.\n\nThis would be especially useful with the way HTML5 outlines documents, where we can have any number of variations of several levels of headings within numerous types of containers (think sections within articles within sections\u2026).\n\nHere is a quick example (copied from the Mozilla blog post about the article) of how -moz-any() works. Instead of writing:\n\nsection section h1, section article h1, section aside h1,\nsection nav h1, article section h1, article article h1,\narticle aside h1, article nav h1, aside section h1,\naside article h1, aside aside h1, aside nav h1, nav section h1,\nnav article h1, nav aside h1, nav nav h1, {\n font-size: 24px;\n}\n\nYou could simply write:\n\n-moz-any(section, article, aside, nav)\n-moz-any(section, article, aside, nav) h1 {\n font-size: 24px;\n}\n\nNice, huh?\n\nMore control over styling form elements\n\nSome are of the opinion that form elements shouldn\u2019t be styled at all, since a user might not recognise them as such if they don\u2019t match the operating system\u2019s controls. I partially agree: I\u2019d rather put the choice in the hands of designers and expect them to be capable of deciding whether their particular design hampers or improves usability.\n\nI would say the same idea applies to font-face: while some fear designers might go crazy and litter their web pages with dozens of different fonts, most welcome the freedom to use something other than Arial or Verdana.\n\nThere will always be someone who will take this freedom too far, but it would be useful if we could, for example, style the default Opera date picker:\n\n\n\n\n\nor Safari\u2019s slider control (think star movie ratings, for example):\n\n\n\n\n\nParent selector\n\nI don\u2019t think there is one CSS author out there who has never come across a case where he or she wished there was a parent selector. There have been many suggestions as to how this could work, but a variation of the child selector is usually the most popular:\n\narticle < h1 {\n\u2026\n}\n\nOne can dream\u2026\n\nFlexible box layout\n\nThe Flexible Box Layout Module sounds a bit like magic: it introduces a new box model to CSS, allowing you to distribute and order boxes inside other boxes, and determine how the available space is shared.\n\nTwo of my favourite features of this new box model are:\n\n\n\tthe ability to redistribute boxes in a different order from the markup\n\tthe ability to create flexible layouts, where boxes shrink (or expand) to fill the available space\n\n\nLet\u2019s take a quick look at the second case. Imagine you have a three-column layout, where the first column takes up twice as much horizontal space as the other two:\n\n\n \n \n \n \n \n\n\nWith the flexible box model, you could specify it like this:\n\nbody {\n display: box;\n box-orient: horizontal;\n}\n#main {\n box-flex: 2;\n}\n#links {\n box-flex: 1;\n}\naside {\n box-flex: 1;\n}\n\nIf you decide to add a fourth column to this layout, there is no need to recalculate units or percentages, it\u2019s as easy as that.\n\nBrowser support for this property is still in its early stages (Firefox and WebKit need their vendor prefixes), but we should start to see it being gradually introduced as more attention is drawn to it (I\u2019m looking at you\u2026). You can read a more comprehensive write-up about this property on the Mozilla developer blog.\n\nIt\u2019s easy to understand why it\u2019s harder to start playing with this module than with things like animations or other more decorative properties, which don\u2019t really break your layouts when users don\u2019t see them. But it\u2019s important that we do, even if only in very experimental projects.\n\nNested selectors\n\nAnyone who has never wished they could do something like the following in CSS, cast the first stone:\n\narticle {\n h1 { font-size: 1.2em; }\n ul { margin-bottom: 1.2em; }\n}\n\nEven though it can easily turn into a specificity nightmare and promote redundancy in your style sheets (if you abuse it), it\u2019s easy to see how nested selectors could be useful. CSS compilers such as Less or Sass let you do this already, but not everyone wants or can use these compilers in their projects.\n\nEvery wish list has an item that could easily be dropped. In my case, I would say this is one that I would ditch first \u2013 it\u2019s the least useful, and also the one that could cause more maintenance problems. But it could be nice.\n\nImplementation of the ::marker pseudo-element\n\nThe CSS Lists module introduces the ::marker pseudo-element, that allows you to create custom list item markers. When an element\u2019s display property is set to list-item, this pseudo-element is created.\n\nUsing the ::marker pseudo-element you could create something like the following:\n\nFootnote 1: Both John Locke and his father, Anthony Cooper, are\nnamed after 17th- and 18th-century English philosophers; the real\nAnthony Cooper was educated as a boy by the real John Locke.\nFootnote 2: Parts of the plane were used as percussion instruments\nand can be heard in the soundtrack.\n\nwhere the footnote marker is generated by the following CSS:\n\nli::marker {\n content: \"Footnote \" counter(notes) \":\";\n text-align: left;\n width: 12em;\n}\nli {\n counter-increment: notes;\n}\n\nYou can read more about how to use counters in CSS in my article from last year.\n\nBear in mind that the CSS Lists module is still a Working Draft and is listed as \u201cLow priority\u201d. I did say this wish list would start to grow more unrealistic closer to the end\u2026\n\nVariables\n\nThe sight of the word \u2018variables\u2019 may make some web designers shy away, but when you think of them applied to things such as repeated colours in your stylesheets, it\u2019s easy to see how having variables available in CSS could be useful.\n\nThink of a website where the main brand colour is applied to elements like the main text, headings, section backgrounds, borders, and so on. In a particularly large website, where the colour is repeated countless times in the CSS and where it\u2019s important to keep the colour consistent, using variables would be ideal (some big websites are already doing this by using server-side technology).\n\nAgain, Less and Sass allow you to use variables in your CSS but, again, not everyone can (or wants to) use these.\n\nIf you are using Less, you could, for instance, set the font-family value in one variable, and simply call that variable later in the code, instead of repeating the complete font stack, like so:\n\n@fontFamily: Calibri, \"Lucida Grande\", \"Lucida Sans Unicode\", Helvetica, Arial, sans-serif;\nbody {\n font-family: @fontFamily;\n}\n\nOther features of these CSS compilers might also be useful, like the ability to \u2018call\u2019 a property value from another selector (accessors):\n\nheader {\n background: #000000;\n}\nfooter {\n background: header['background'];\n}\n\nor the ability to define functions (with arguments), saving you from writing large blocks of code when you need to write something like, for example, a CSS gradient:\n\n.gradient (@start:\"\", @end:\"\") {\n background: -webkit-gradient(linear, left top, left bottom, from(@start), to(@end));\n background: -moz-linear-gradient(-90deg,@start,@end);\n}\nbutton {\n .gradient(#D0D0D0,#9F9F9F);\n}\n\nStandardised comments\n\nEach CSS author has his or her own style for commenting their style sheets. While this isn\u2019t a massive problem on smaller projects, where maybe only one person will edit the CSS, in larger scale projects, where dozens of hands touch the code, it would be nice to start seeing a more standardised way of commenting.\n\nOne attempt at creating a standard for CSS comments is CSSDOC, an adaptation of Javadoc (a documentation generator that extracts comments from Java source code into HTML). CSSDOC uses \u2018DocBlocks\u2019, a term borrowed from the phpDocumentor Project. A DocBlock is a human- and machine-readable block of data which has the following structure:\n\n/**\n * Short description\n *\n * Long description (this can have multiple lines and contain
tags\n *\n * @tags (optional)\n */\n\nCSSDOC includes a standard for documenting bug fixes and hacks, colours, versioning and copyright information, amongst other important bits of data.\n\nI know this isn\u2019t a CSS feature request per se; rather, it\u2019s just me pointing you at something that is usually overlooked but that could contribute towards keeping style sheets easier to maintain and to hand over to new developers.\n\nFinal notes\n\nI understand that if even some of these were implemented in browsers now, it would be a long time until all vendors were up to speed. But if we don\u2019t talk about them and experiment with what\u2019s available, then it will definitely never happen.\n\nWhy haven\u2019t I mentioned better browser support for existing CSS3 properties? Because that would be the same as adding chocolate to your Christmas wish list \u2013 you don\u2019t need to ask, everyone knows you want it.\n\nThe list could go on. There are dozens of other things I would love to see integrated in CSS or further developed. These are my personal favourites: some might be less useful than others, but I\u2019ve wished for all of them at some point.\n\nPart of the research I did while writing this article was asking some friends what they would add to their lists; other than a couple of items I already had in mine, everything else was different. I\u2019m sure your list would be different too.

{"rowid": 217, "title": "Beyond Web Mechanics \u2013 Creating Meaningful Web Design", "contents": "It was just over three years ago when I embarked on becoming a web designer, and the first opinion piece about the state of web design I came across was a conference talk by Elliot Jay Stocks called \u2018Destroy the Web 2.0 Look\u2019. Elliot\u2019s presentation was a call to arms, a plea to web designers the world over to stop the endless reproductions of the so called \u2018Web 2.0 look\u2019.\n\nThree and a half years on from Elliot\u2019s talk, what has changed? Well, from an aesthetic standpoint, not a whole lot. The Web 2.0 look has evolved, but it\u2019s still with us and much of the web remains filled with cookie cutter websites that bear a striking resemblance to one another. This wouldn\u2019t matter so much if these websites were selling comparable services or products, but they\u2019re not. They look similar, they follow the same web design trends; their aesthetic style sends out a very similar message, yet they\u2019re selling completely different services or products. How can you be communicating effectively with your users when your online book store is visually indistinguishable from an online cosmetic store? This just doesn\u2019t make sense. \n\nI don\u2019t want to belittle the current version of the Web 2.0 look for the sake of it. I want to talk about the opportunity we have as web designers to create more meaningful experiences for the people using our websites. Using design wisely gives us the ability to communicate messages, ideas and attitudes that our users will understand and connect with.\n\nBeing human\n\nAs human beings we respond emotionally to everything around us \u2013 people, objects, posters, packaging or websites. We also respond in different ways to different kinds of aesthetic design and style. We care about style and aesthetics deeply, whether we realise it or not. Aesthetic design has the power to attract or repel. We often make decisions based purely on aesthetics and style \u2013 and don\u2019t retailers the world over know it! We connect attitudes and strongly held beliefs to style. Individuals will proudly associate themselves with a certain style or aesthetic because it\u2019s an expression of who they are. You know that old phrase, \u2018Don\u2019t judge a book by its cover\u2019? Well, the problem is that people do, so it\u2019s important we get the cover right.\n\nMuch is made of how to structure web pages, how to create a logical information hierarchy, how to use layout and typography to clearly communicate with your users. It\u2019s important, however, not to mistake clarity of information or legibility with getting your message across. Few users actually read websites word by word: it\u2019s far more likely they\u2019ll just scan the page. If the page is copy-heavy and nothing grabs their attention, they may well just move on. This is why it\u2019s so important to create a visual experience that actually means something to the user. \n\nMeaningful design\n\nWhen we view a poster or website, we make split-second assessments and judgements of what is in front of us. Our first impressions of what a website does or who it is aimed at are provoked by the style and aesthetic of the website. For example, with clever use of colour, typography, graphic design and imagery we can communicate to users that an organisation is friendly, edgy, compassionate, fun or environmentally conscious.\n\nUsing a certain aesthetic we can convey the personality of that organisation, target age ranges, different sexes or cultural groups, communicate brand attributes, and more. We can make our users feel like they\u2019re part of something and, perhaps even more importantly, we can make new users want to be a part of something. And we can achieve all this before the user has read a single word. \n\nBy establishing a website\u2019s aesthetic and creating a meaningful visual language, a design is no longer just a random collection of pretty gradients that have been plucked out of thin air. There can be a logic behind the design decisions we make. So, before you slap another generic piece of ribbon or an ultra shiny icon into the top-left corner of your website, think about why you are doing it. If you can\u2019t come up with a reason better than \u201cI saw it on another website\u201d, it\u2019s probably a poor application of style.\n\nDesign and style\n\nThere are a number of reasons why the web suffers from a lack meaningful design. Firstly, there are too many preconceptions of what a website should look like. It\u2019s too easy for designers to borrow styles from other websites, thereby limiting the range of website designs we see on the web. Secondly, many web designers think of aesthetic design as of secondary importance, which shouldn\u2019t be the case. Designing websites that are accessible and easy to use is, of course, very important but this is the very least a web designer should be delivering. Easy to use websites should come as standard \u2013 it\u2019s equally important to create meaningful, compelling and beautiful experiences for everyone who uses our websites. The aesthetics of your site are part of the design, and to ignore this and play down the role of aesthetic design is just a wasted opportunity. \n\nNo compromise necessary\n\nEasy to use, accessible websites and beautiful, meaningful aesthetics are not mutually exclusive. The key is to apply style and aesthetic design appropriately. We need to think about who and what we\u2019re designing for and ask ourselves why we\u2019re applying a certain kind of aesthetic style to our design. If you do this, there\u2019s no reason why effective, functional design should come at the expense of jaw-dropping, meaningful aesthetics.\n\nWeb designers need to understand the differences between functional design and aesthetic design but, even more importantly, they need to know how to make them work together. It\u2019s combining these elements of design successfully that makes for the best web design in the world.", "year": "2010", "author": "Mike Kus", "author_slug": "mikekus", "published": "2010-12-05T00:00:00+00:00", "url": "https://24ways.org/2010/beyond-web-mechanics-creating-meaningful-web-design/", "topic": "design"}
{"rowid": 232, "title": "Optimize Your Web Design Workflow", "contents": "I\u2019m not sure about you, but I still favour using Photoshop to create my designs for the web. I agree that this application, even with its never-ending feature set, is not the perfect environment to design websites in. The ideal application doesn\u2019t exist yet, however, so until it does it\u2019s maybe not such a bad idea to investigate ways to optimize our workflow.\n\nWhy use Photoshop?\n\nIt will probably not come as a surprise if I say that Photoshop and Illustrator are the applications that I know best and feel most comfortable and creative in. Some people prefer Fireworks for web design. Even though I understand people\u2019s motivations, I still prefer Photoshop personally. On the occasions that I gave Fireworks a try, I ended up just using the application to export my images as slices, or to prepare a dummy for the client. For some reason, I\u2019ve never been able to find my way in that app. There were always certain things missing that could only be done in either Photoshop or Illustrator, which bothered me.\n\nWhy not start in the browser?\n\nThese days, with CSS3 styling emerging, there are people who find it more efficient to design in the browser. I agree that at a certain point, once the basic design is all set and defined, you can jump right into the code and go from there. But the actual creative part, at least for me, needs to be done in an application such as Photoshop.\n\nAs a designer I need to be able to create and experiment with shapes on the fly, draw things, move them around, change colours, gradients, effects, and so on. I can\u2019t see me doing this with code. I\u2019m sure if I switch to markup too quickly, I might end up with a rather boxy and less interesting design. Once I start playing with markup, I leave my typical \u2018design zone\u2019. My brain starts thinking differently \u2013 more rational and practical, if you know what I mean; I start to structure and analyse how to mark up my design in the most efficient semantic way. When I design, I tend to let that go for a bit. I think more freely and not so much about the limitations, as it might hinder my creativity. Now that you know my motivations to stick with Photoshop for the time being, let\u2019s see how we can optimize this beast.\n\nOptimize your Photoshop workspace\n\nIn Photoshop CS5 you have a few default workspace options to choose from which can be found at the top right in the Application Bar (Window\u2009>\u2009Application Bar).\n\n\n\nYou can set up your panels and palettes the way you want, starting from the \u2018Design\u2019 workspace option, and save this workspace for future web work. Here is how I have set up things for when I work on a website design:\n\n\n\nI have the layers palette open, and I keep the other palettes collapsed. Sometimes, when space permits, I open them all. For designers who work both on print and web, I think it\u2019s worthwhile to save a workspace for both, or for when you\u2019re doing photo retouching.\n\nSet up a grid\n\nWhen you work a lot with Shape Layers like I do, it\u2019s really helpful to enable the Grid (View\u2009>\u2009Show\u2009>\u2009Grid) in combination with Snap to Grid (View\u2009>\u2009Snap To\u2009>\u2009Grid). This way, your vector-based work will be pixel-sharp, as it will always snap to the grid, and so you don\u2019t end up with blurry borders.\n\n\n\nTo set up your preferred grid, go to Preferences\u2009>\u2009Guides, Grids and Slices. A good setting is to use \u2018Gridline Every 10 pixels\u2019 and \u2018Subdivision 10\u2019. You can switch it on and off at any time using the shortcut Cmd/Ctrl + \u2019.\n\n\n\nIt might also help to turn on Smart Guides (View\u2009>\u2009Show\u2009>\u2009Smart Guides).\n\nAnother important tip for making sure your Shape Layer boxes and other shapes are perfectly aligned to the pixel grid when you draw them is to enable Snap to Pixels. This option can be enabled in the Application bar in the Geometry options dropdown menu when you select one of the shape tools from the toolbox.\n\n\n\nUse Shape Layers\n\nTo keep your design as flexible as possible, it\u2019s a good thing to use Shape Layers wherever you can as they are scalable. I use them when I design for the iPhone. All my icons, buttons, backgrounds, illustrative graphics \u2013 they are all either Smart Objects placed from Illustrator, or Shape Layers. This way, the design is scalable for the retina display.\n\n\n\nUse Smart Objects\n\nAmong the things I like a lot in Photoshop are Smart Objects. Smart Objects preserve an image\u2019s source content with all its original characteristics, enabling you to perform non-destructive editing to the layer. For me, this is the ideal way of making my design flexible.\n\n\n\nFor example, a lot of elements are created in Illustrator and are purely vector-based. Placing these elements in Photoshop as Smart Objects (via copy and paste, or dragging from Illustrator into Photoshop) will keep them vector-based and scalable at all times without loss of quality.\n\n\n\nAnother way you could use Smart Objects is whenever you have repeating elements; for example, if you have a stream or list of repeating items. You could, for instance, create one, two or three different items (for the sake of randomness), make each one a Smart Object, and repeat them to create the list. Then, when you have to update, you need only change the Smart Object, and the update will be automatically applied in all its linked instances.\n\nTurning photos into Smart Objects before you resize them is also worth considering \u2013 you never know when you\u2019ll need that same photo just a bit bigger. It keeps things more flexible, as you leave room to resize the image at a later stage. I use this in combination with the Smart Filters a lot, as it gives me such great flexibility.\n\n\n\nI usually use Smart Objects as well for the main sections of a web page, which are repeated across different pages of a site. So, for elements such as the header, footer and sidebar, it can be handy for bigger projects that are constantly evolving, where you have to create a lot of different pages in Photoshop.\n\nYou could save a template page that has the main sections set up as Smart Objects, always in their latest version. Each time you need to create new page, you can start from that template file. If you need to update an existing page because the footer (or sidebar, or header) has been updated, you can drag the updated Smart Object into this page. Although, do I wish Photoshop made it possible to have Smart Objects live as separate files, which are then linked to my different pages. Then, whenever I update the Smart Object, the pages are automatically updated next time I open the file. This is how linked files work in InDesign and Illustrator when you place a external image.\n\nUse Layer Comps\n\nIn some situations, using Layer Comps can come in handy. I try to use them when the design consists of different states; for example, if there are hidden and show states of certain content, such as when content is shown after clicking a certain button. It can be useful to create a Layer Comp for each state. So, when you switch between the two Layer Comps, you\u2019re switching between the two states.\n\n\n\nIt\u2019s OK to move or hide content in each of these states, as well as apply different layer styles. I find this particularly useful when I need to save separate JPEG versions of each state to show to the client, instead of going over all the eye icons in the layers palette to turn the layers\u2019 visibility on or off.\n\n\n\nCreate a set of custom colour swatches\n\nI tend to use a distinct colour Swatches palette for each project I work on, by saving a separate Swatches palette in project\u2019s folder (as an .ase file). You can do this through the palette\u2019s dropdown menu, choosing Save Swatches for Exchange.\n\n\n\nSelecting this option gives you the flexibility to load this palette in other Adobe applications like Illustrator, InDesign or Fireworks. This way, you have the colours of any particular project at hand. I name each colour, using the hexadecimal values.\n\n\n\nLoading, saving or changing the view of the Swatches palette can be done via the palette\u2019s dropdown menu. My preferred view is \u2018Small List\u2019 so I can see the hexadecimal values or other info I have added in the description.\n\nI do wish Photoshop had the option of loading several different Styles palettes, so I could have two or more of them open at the same time, but each as a separate palette. This would be handy whenever I switch to another project, as I\u2019m usually working on more than one project in a day. At the moment, you can only add a set of colours to the palette that is already open, which is frustrating and inefficient if you need to update the palette of a project separately.\n\nCreate a set of custom Styles\n\nJust like saving a Swatches palette, I also always save the styles I apply in the Styles palette as a separate Styles file in the project\u2019s folder when I work on a website design or design for iPhone/iPad. During the design process, I can save it each time styles are added. Again, though, it would be great if we could have different Styles palettes open at the same time.\n\n\n\nUse a scratch file\n\nWhat I also find particularly timesaving, when working on a large project, is using some kind of scratch file. By that, I mean a file that has elements in place that you reuse a lot in the general design. Think of buttons, icons and so on, that you need in every page or screen design. This is great for both web design work and iPad/iPhone work. \n\n\n\nUse the slice tool\n\nThis might not be something you think of at first, because you probably associate this way of working with \u2018old-school\u2019 table-based techniques. Still, you can apply your slice any way you want, keeping your way of working in mind. Just think about it for a second. If you use the slice tool, and you give each slice its proper filename, you don\u2019t have to worry about it when you need to do updates on the slice or image. Photoshop will remember what the image of that slice is called and which \u2018Save for Web\u2019 export settings you\u2019ve used for it. You can also export multiple slices all at once, or export only the ones you need using \u2018Save selected slices\u2019.\n\n\n\nI hope this list of optimization tips was useful, and that they will help you improve and enjoy your time in Photoshop. That is, until the ultimate web design application makes its appearance.
