This is sometimes referred to as an \u201cem driven design\u201d (we\u2019ll see why in a moment).\n\nTo see how this works in practice, here\u2019s the same design with the text \u201czoomed\u201d up in size\n\n\n\nand the same design again, when we zoom the text size down\n\n\n\nBy the way, the hCard image comes from Chris Messina, and you can download it and other microformat icons from the microformats wiki.\n\nNow, with CSS3, this whole task would be considerably easier, because we can add multiple background images to an element, and border images for each edge of an element. Safari, version 1.3 up, actually supports multiple background images, but sadly, it\u2019s not supported in Firefox 1.5, or even Firefox 2.0 (let\u2019s not mention IE7 eh?). So it\u2019s probably too little supported to use now. So instead we\u2019ll use a technique that only involves CSS2, and works in pretty much any browser.\n\nVery often, developers add div or span elements as containers for these background images, and in fact, if you visit Scott Shiller\u2019s site, that\u2019s what he has done there. But if at all possible we shouldn\u2019t be adding any HTML simply for presentational purposes, even if the presentation is done via CSS. What we can do is to use the HTML we have already, as much as is possible, to add the style we want. This can take some creative thinking, but once you get the hang of this approach it becomes a more natural way of using HTML compared with simply adding divs and spans at will as hooks for style. Of course, this technique isn\u2019t always simple, and in fact sometimes simply not possible, requiring us to add just a little HTML to provide the \u201chooks\u201d for CSS.\n\nLet\u2019s go to work\n\nThe first step is to add a background image to the whole vCard element.\n\n\n\nWe make this wide enough (for example 1000 or more pixels) and tall enough that no matter how large the content of the vCard grows, it will never overflow this area. We can\u2019t simply repeat the image, because the top left corner will show when the image repeats.\n\nWe add this as the background image of the vCard element using CSS.\n\nWhile we are at it, let\u2019s give the text a sans-serif font, some color so that it will be visible, and stop the image repeating.\n\n.vcard {\n\tbackground-image: url(images/vcardfill.png);\n\tbackground-repeat: no-repeat;\n\tcolor: #666;\n\tfont-family: \"Lucida Grande\", Verdana, Helvetica, Arial, sans-serif;\n}\n\nWhich in a browser, will look something like this.\n\n\n\nNext step we need to add the top right hand corner of the hCard. In keeping with our aim of not adding HTML simply for styling purposes, we want to use the existing structure of the page where possible. Here, we\u2019ll use the paragraph of class fn and org, which is the first child element of the vcard element.\n\n
Web Directions Conference Pty Ltd
\n\nHere\u2019s our CSS for this element\n\n.fn {\n\tbackground-image: url(images/topright.png);\n\tbackground-repeat: no-repeat;\n\tbackground-position: top right;\n\tpadding-top: 2em;\n\tfont-weight: bold;\n\tfont-size: 1.1em;\n}\n\nAgain, we don\u2019t want it to repeat, but this time, we\u2019ve specified a background position for the image. This will make the background image start from the top, but its right edge will be located at the right edge of the element. I also made the font size a little bigger, and the weight bold, to differentiate it from the rest of the text in the hCard.\n\nHere\u2019s the image we are adding as the background to this element.\n\n\n\nSo, putting these two CSS statements together we get\n\n\n\nWe specified a padding-top of 2em to give some space between the content of the fn element and the edge of the fn element. Otherwise the top of the hCard image would be hard against the border. To see this in action, just remove the padding-top: 2em; declaration and preview in a browser.\n\nSo, with just two statements, we are well under way. We\u2019ve not even had to add any HTML so far. Let\u2019s turn to the bottom of the element, and add the bottom border (well, the background image which will serve as that border).\n\nNow, which element are we going to use to add this background image to?\n\nOK, here I have to admit to a little, teensie bit of cheating. If you look at the HTML of the hCard, I\u2019ve grouped the email and telephone properties into a div, with a class of telecommunications. This grouping is not strictly requred for our hCard.\n\n
\n\nNow, I chose that class name because that is what the vCard specification calls this group of properties. And typically, I do tend to group together related elements using divs when I mark up content. I find it makes the page structure more logical and readable. But strictly speaking, this isn\u2019t necessary, so you may consider it cheating. But my lesson in this would be, if you are going to add markup, try to make it as meaningful as possible.\n\nAs you have probably guessed by now, we are going to add one part of the bottom border image to this element. We\u2019re going to add this image as the background-image.\n\n\n\nAgain, it will be a very wide image, like the top left one, so that no matter how wide the element might get, the background image will still be wide enough. Now, we\u2019ll need to make this image sit in the bottom left of the element we attach it to, so we use a backgound position of left bottom (we put the horizontal position before the vertical). Here\u2019s our CSS statement for this\n\n.telecommunications {\n\tbackground-image: url(images/bottom-left.png);\n\tbackground-repeat: no-repeat;\n\tbackground-position: left bottom;\n\tmargin-bottom: 2em;\n}\n\nAnd that will look like this\n\n\n\nNot quite there, but well on the way. Time for the final piece in the puzzle.\n\nOK, I admit, I might have cheated just a little bit more in this step. But like the previous step, all valid, and (hopefully) quite justifiable markup. If we look at the HTML again, you\u2019ll find that our email address is marked up like this\n\n
Email: info@webdirections.org
\n\nTypically, in hCard, the value part of this property isn\u2019t required, and we could get away with\n\n
info@webdirections.org \n\nThe form I\u2019ve used, with the span of class value is however, perfectly valid hCard markup (hard allows for multiple email addresses of different types, which is where this typically comes in handy). Why have I gone to all this trouble? Well, when it came to styling the hCard, I realized I needed a block element to attach the background image for the bottom right hand corner to. Typically the last block element in the containing element is the ideal choice (and sometimes it\u2019s possible to take an inline element, for example the link here, and use CSS to make it a block element, and attach it to that, but that really doesn\u2019t work with this design).\n\nSo, if we are going to use the paragraph which contains the email link, we need a way to select it exclusively, which means that with CSS2 at least, we need a class or id as a hook for our CSS selector (in CSS3 we could use the last-child selector, which selects the last child element of a specified element, but again, as last child is not widely supported, we won\u2019t rely on it here.)\n\nSo, the least worst thing we could do is take an existing element, and add some reasonably meaningful markup to it. That\u2019s why we gave the paragraph a class of email, and the email address a class of value. Which reminds me a little of a moment in Hamlet\n\n\n\tThe lady doth protest too much, methinks\n\n\nOK, let\u2019s get back to the CSS.\n\nWe add the bottom right corner image, positioning it in the bottom right of the element, and making sure it doesn\u2019t repeat. We also add some padding to the bottom, to balance out the padding we added to the top of the hCard.\n\np.email {\n\tbackground-image: url(images/bottom-right.png);\n\tbackground-position: right bottom;\n\tbackground-repeat: no-repeat;\n\tpadding-bottom: 2em;\n}\n\nWhich all goes to make our hCard look like this\n\n\n\nIt just remains for us to clean up a little.\n\nLet\u2019s start from the top. We\u2019ll float the download image to the right like this\n\n.vcard img {\n\tfloat: right;\n\tpadding-right: 1em;\n\tmargin-top: -1em\n}\n\nSee how we didn\u2019t have to add a class to style the image, we used the fact that the image is a descendent of the vcard element, and a descendent selector. In my experience, the very widely supported, powerful descendent selector is one of the most underused aspects of CSS. So if you don\u2019t use it frequently, look into it in more detail.\n\nWe added some space to the right of the image, and pulled it up a bit closer to the top of the hCard, like this\n\n\n\nWe also want to add some whitespace between the edge of the hCard and the text. We would typically add padding to the left of the containing element, (in this case the vcard element) but this would break our bottom left hand corner, like this\n\n\n\nThat\u2019s because the div element we added this bottom left background image to would be moved in by the padding on its containing element.\n\nSo instead, we add left margin to all the paragraphs in the hCard\n\n.vcard p {\n\tmargin-left: 1em;\n}\n\n(there is the descendent selector again \u2013 it is the swiss army knife of CSS)\n\nNow, we\u2019ve not yet made the width of the hCard a function of the size of the text inside it (or \u201cem driven\u201d as we described it earlier). We do this by giving the hCard a width that is specified in em units. Here we\u2019ll set a width of say 28em, which makes the hCard always roughly as wide as 28 characters (strictly speaking 28 times the width of the letter capital M). \n\nSo the statement for our containing vcard element becomes\n\n.vcard {\n\tbackground-image: url(images/vcardfill.png);\n\tbackground-repeat: no-repeat;\n\tcolor: #666;\n\tfont-family: \"Lucida Grande\", Verdana, Helvetica, Arial, sans-serif;\n\twidth: 28em;\n}\n\nand now our element will look like this\n\n\n\nWe\u2019ve used almost entirely the existing HTML from our original hCard (adding just a little, and trying as much as possible to keep that additional markup meaningful), and just 6 CSS statements.\n\nHoliday Bonus \u2013 a downloadable vCard\n\nDid you notice this part of the HTML\n\n

\n\n\nYour first transformation\n\nYour first XSL will look something like this:\n\n\n\n\t\n \n\nThis is pretty much the starting point for most XSL files. You will notice the standard XML processing instruction at the top of the file (line 1). We then switch into XSL mode using the XSL namespace on all XSL elements (line 2). In this case, we have added namespaces for ATOM (line 4) and Dublin Core (line 5). This means the XSL can now read and understand those elements from the source XML. \n\nAfter we define all the namespaces, we then move onto the xsl:output element (line 6). This enables you to define the final method of output. Here we\u2019re specifying html, but you could equally use XML or Text, for example. The encoding attributes on each element do what they say on the tin. As with all XML, of course, we close every element including the root.\n\nThe next stage is to add a template, in this case an \n\t\n\t\n\t\t\n\t\t\t\n\t\t\t\tMaking XML beautiful again : Transforming ATOM \n\t\t\t\n\t\t\t\n\t\t\t\t\n\t\t\t\n\t\t\n\t \n \n\nThe beautiful thing about XSL is its English syntax, if you say it out loud it tends to make sense. \n\nThe / value for the match attribute on line 8 is our first example of XPath syntax.

{"rowid": 130, "title": "Faster Development with CSS Constants", "contents": "Anyone even slightly familiar with a programming language will have come across the concept of constants \u2013 a fixed value that can be used through your code. For example, in a PHP script I might have a constant which is the email address that all emails generated by my application get sent to. \n\n$adminEmail = 'info@example.com';\n\nI could then use $adminEmail in my script whenever I wanted an email to go to that address. The benefit of this is that when the client decides they want the email to go to a different address, I only need change it in one place \u2013 the place where I initially set the constant. I could also quite easily make this value user defined and enable the administrator to update the email address.\n\nUnfortunately CSS doesn\u2019t support constants. It would be really useful to be able to define certain values initially and then use them throughout a CSS file, so in this article I\u2019m going to take a look at some of the methods we do have available and provide pointers to more in depth commentary on each. If you have a different method, or tip to share please add it to the comments.\n\nSo what options do we have?\n\nOne way to get round the lack of constants is to create some definitions at the top of your CSS file in comments, to define \u2018constants\u2019. A common use for this is to create a \u2018color glossary\u2019. This means that you have a quick reference to the colors used in the site to avoid using alternates by mistake and, if you need to change the colors, you have a quick list to go down and do a search and replace. \n\nIn the below example, if I decide I want to change the mid grey to #999999, all I need to do is search and replace #666666 with #999999 \u2013 assuming I\u2019ve remember to always use that value for things which are mid grey.\n\n/*\nDark grey (text): #333333\nDark Blue (headings, links) #000066\nMid Blue (header) #333399\nLight blue (top navigation) #CCCCFF\nMid grey: #666666\n*/\n\nThis is a fairly low-tech method, but if used throughout the development of the CSS files can make changes far simpler and help to ensure consistency in your color scheme.\n\nI\u2019ve seen this method used by many designers however Garrett Dimon documents the method, with more ideas in the comments.\n\nGoing server-side\n\nTo truly achieve constants you will need to use something other than CSS to process the file before it is sent to the browser. You can use any scripting language \u2013 PHP, ASP, ColdFusion etc. to parse a CSS file in which you have entered constants. So that in a constants section of the CSS file you would have:\n\n$darkgrey = '#333333';\n$darkblue = '#000066';\n\nThe rest of the CSS file is as normal except that when you come to use the constant value you would use the constant name instead of adding the color:\n\np {\n\tcolor: $darkgrey;\n}\n\nYour server-side script could then parse the CSS file, replace the constant names with the constant values and serve a valid CSS file to the browser. Christian Heilmann has done just this for PHP however this could be adapted for any language you might have available on your server.\n\nShaun Inman came up with another way \n of doing this that removes the need to link to a PHP script and also enables the adding of constants using the syntax of at-rules . This method is again using PHP and will require you to edit an .htaccess file. \n\nA further method is to generate static CSS files either using a script locally \u2013 if the constants are just to enable speed of development \u2013 or as part of the web application itself. Storing a template stylesheet with constant names in place of the values you will want to update means that your script can simply open the template, replace the variables and save the result as a new stylesheet file.\n\nWhile CSS constants are a real help to developers, they can also be used to add new functionality to your applications. As with the email address example that I used at the beginning of this article, using a combination of CSS and server-side scripting you could enable a site administrator to select the colours for a new theme to be used on a page of a content managed site. By using constants you need only give them the option to change certain parts of the CSS and not upload a whole different CSS file, which could lead to some interesting results!\n\nAs we are unlikely to find real CSS constants under the tree this Christmas the above methods are some possibilities for better management of your stylesheets. However if you have better methods, CSS Constant horror stories or any other suggestions, add your comments below.", "year": "2006", "author": "Rachel Andrew", "author_slug": "rachelandrew", "published": "2006-12-02T00:00:00+00:00", "url": "https://24ways.org/2006/faster-development-with-css-constants/", "topic": "process"}

{"rowid": 128, "title": "Boost Your Hyperlink Power", "contents": "There are HTML elements and attributes that we use every day. Headings, paragraphs, lists and images are the mainstay of every Web developer\u2019s toolbox. Perhaps the most common tool of all is the anchor. The humble a element is what joins documents together to create the gloriously chaotic collection we call the World Wide Web.\n\nAnatomy of an Anchor\n\nThe power of the anchor element lies in the href attribute, short for hypertext reference. This creates a one-way link to another resource, usually another page on the Web:\n\n\n\nThe href attribute sits in the opening a tag and some descriptive text sits between the opening and closing tags:\n\n Drew McLellan \n\n\u201cWhoop-dee-freakin\u2019-doo,\u201d I hear you say, \u201cthis is pretty basic stuff\u201d \u2013 and you\u2019re quite right. But there\u2019s more to the anchor element than just the href attribute.\n\nThe Theory of relativity\n\nYou might be familiar with the rel attribute from the link element. I bet you\u2019ve got something like this in the head of your documents:\n\nmy RSS feed .\n\nYou can add extra information to this anchor using the rel attribute:\n\nSubscribe to my RSS feed .\n\nThere\u2019s no prescribed list of values for the rel attribute so you can use whatever you decide is semantically meaningful. Let\u2019s say you\u2019ve got a complex e-commerce application that includes a link to a help file. You can explicitly declare the relationship of the linked file as being \u201chelp\u201d:\n\nneed help? \n\nElemental Microformats\n\nAlthough it\u2019s completely up to you what values you use for the rel attribute, some consensus is emerging in the form of microformats. Some of the simplest microformats make good use of rel. For example, if you are linking to a license that covers the current document, use the rel-license microformat:\n\nLicensed under a Creative Commons attribution license \n\nThat describes the relationship of the linked document as \u201clicense.\u201d\n\nThe rel-tag microformat goes a little further. It uses rel to describe the final part of the URL of the linked file as a \u201ctag\u201d for the current document:\n\nLearn more about semantic markup \n\nThis states that the current document is being tagged with the value \u201cMicroformats.\u201d\n\nXFN, which stands for XHTML Friends Network, is a way of describing relationships between people:\n\nDrew McLellan \n\nThis microformat makes use of a very powerful property of the rel attribute. Like the class attribute, rel can take multiple values, separated by spaces:\n\nDrew McLellan \n\nHere I\u2019m describing Drew as being a friend, someone I\u2019ve met, and a colleague (because we\u2019re both Web monkies).\n\nYou Say You Want a revolution\n\nWhile rel describes the relationship of the linked resource to the current document, the rev attribute describes the reverse relationship: it describes the relationship of the current document to the linked resource. Here\u2019s an example of a link that might appear on help.html:\n\ncontinue shopping \n\nThe rev attribute declares that the current document is \u201chelp\u201d for the linked file.\n\nThe vote-links microformat makes use of the rev attribute to allow you to qualify your links. By using the value \u201cvote-for\u201d you can describe your document as being an endorsement of the linked resource:\n\nI agree with Richard Dawkins .\n\nThere\u2019s a corresponding vote-against value. This means that you can link to a document but explicitly state that you don\u2019t agree with it.\n\nI agree with Richard Dawkins \nabout those creationists . \n\nOf course there\u2019s nothing to stop you using both rel and rev on the same hyperlink:\n\nRichard Dawkins \n\nThe Wisdom of Crowds\n\nThe simplicity of rel and rev belies their power. They allow you to easily add extra semantic richness to your hyperlinks. This creates a bounty that can be harvested by search engines, aggregators and browsers.

(For more about this issue and some test examples, there\u2019s a thread at accessify forum which wanders in that direction.)\n\nOne further issue for screen reader users is implied by the design: the input fields are associated together in rows and columns, and a sighted user can visually scan across and down to make those associations; but a blind user can\u2019t do that. For such a user the row and column header data will need to be there at every axis; in other words, the layout should be more like this:\n\n\n\nAnd constructed with appropriate semantic markup to convey those relationships. By this point the selection of elements seems pretty clear: each row is a fieldset, the row header is a legend, and each column header is a label, associated with an input.\n\nHere\u2019s what that form looks like with no CSS:\n\n\n\nAnd here\u2019s some markup for the first row (with most of the attributes removed just to keep this example succinct):\n\n\n\t\n\t\tMatch points \n\t \n\t\n\t\tWin \n\t\t \n\t\n\t\tDraw \n\t\t \n\t\n\t\tLose \n\t\t \n\t\n\t\tPlayed \n\t\t \n \n\nThe span inside each legend is because legend elements are highly resistant to styling! Indeed they\u2019re one of the most stubborn elements in the browsers\u2019 vocabulary. Oh man \u2026 how I wrestled with the buggers \u2026 until this obvious alternative occurred to me! So the legend element itself is just a container, while all the styling is on the inner span.\n\nOh yeah, there was some CSS too\n\nI\u2019m not gonna dwell too much on the CSS it took to make this work \u2013 this is a short article, and it\u2019s all there in the demo [demo page, style sheet]\n\nBut I do want to touch on the most interesting bit \u2013 where we get from a layout with headers on every row, to one where only the top row has headers \u2013 or at least, so it appears to graphical browsers. For screen readers, as we noted, we need those headers on every row, so we should employ some cunning CSS to partly negate their visual presence, without removing them from the output.\n\nThe core styling for each label span is like this:\n\nlabel span\n{\n\tdisplay:block;\n\tpadding:5px;\n\tline-height:1em;\n\tbackground:#423221;\n\tcolor:#fff;\n\tfont-weight:bold;\n}\n\nBut in the rows below the header they have these additional rules:\n\nfieldset.body label span\n{\n\tpadding:0 5px;\n\tline-height:0;\n\tposition:relative;\n\ttop:-10000em;\n}\n\nThe rendered width of the element is preserved, ensuring that the surrounding label is still the same width as the one in the header row above, and hence a unified column width is preserved all the way down. But the element effectively has no height, and so it\u2019s effectively invisible. The styling is done this way, rather than just setting the height to zero and using overflow:hidden, because to do that would expose an unrelated quirk with another popular screen reader! (It would hide the output from Window Eyes, as shown in this test example at access matters.)\n\nThe finished widget\n\nIt\u2019s an intricate beast allright! But after all that we do indeed get the widget we want:\n\n\n\tDemo page\n\tStyle sheet\n\n\nIt\u2019s not perfect, most notably because the legends have to have a fixed width; this can be in em to allow for text scaling, but it still doesn\u2019t allow the content to break into multiple lines. It also doesn\u2019t look quite right in Safari; and some CSS hacking was needed to make it look right in IE6 and IE7.\n\nStill it worked well enough for the purpose, and satisfied the client completely. And most of all it re-assured me in my faith \u2013 that there\u2019s never any need to abuse tables for layout.

{"rowid": 126, "title": "Intricate Fluid Layouts in Three Easy Steps", "contents": "The Year of the Script may have drawn attention away from CSS but building fluid, multi-column, cross-browser CSS layouts can still be as unpleasant as a lump of coal. Read on for a worry-free approach in three quick steps.\n\nThe layout system I developed, YUI Grids CSS, has three components. They can be used together as we\u2019ll see, or independently.\n\nThe Three Easy Steps\n\n\n\tChoose fluid or fixed layout, and choose the width (in percents or pixels) of the page.\n\tChoose the size, orientation, and source-order of the main and secondary blocks of content.\n\tChoose the number of columns and how they distribute (for example 50%-50% or 25%-75%), using stackable and nestable grid structures.\n\n\nThe Setup\n\nThere are two prerequisites: We need to normalize the size of an em and opt into the browser rendering engine\u2019s Strict Mode.\n\nEms are a superior unit of measure for our case because they represent the current font size and grow as the user increases their font size setting. This flexibility\u2014the container growing with the user\u2019s wishes\u2014means larger text doesn\u2019t get crammed into an unresponsive container. We\u2019ll use YUI Fonts CSS to set the base size because it provides consistent-yet-adaptive font-sizes while preserving user control.\n\nThe second prerequisite is to opt into Strict Mode (more info on rendering modes) by declaring a Doctype complete with URI. You can choose XHTML or HTML, and Transitional or Strict. I prefer HTML 4.01 Strict, which looks like this:\n\n\n\nIncluding the CSS\n\nA single small CSS file powers a nearly-infinite number of layouts thanks to a recursive system and the interplay between the three distinct components. You could prune to a particular layout\u2019s specific needs, but why bother when the complete file weighs scarcely 1.8kb uncompressed? Compressed, YUI Fonts and YUI Grids combine for a miniscule 0.9kb over the wire.\n\nYou could save an HTTP request by concatenating the two CSS files, or by adding their contents to your own CSS, but I\u2019ll keep them separate for now:\n\n
\n\n\nAll pages are centered within the viewport, and grow with font size. The 100% width page (doc3) preserves 10px of breathing room via left and right margins. If you prefer your content flush to the viewport, just add doc3 {margin:auto} to your CSS.\n\nRegardless of what you choose in the other two steps, you can always toggle between these widths and behaviors by simply swapping the ID value. It\u2019s really that simple.\n\nExample: 100% fluid layout\n\nStep 2: Choose a Template Preset\n\nThis is perhaps the most frequently omitted step (they\u2019re all optional), but I use it nearly every time. In a source-order-independent way (good for accessibility and SEO), \u201cTemplate Presets\u201d provide commonly used template widths compatible with ad-unit dimension standards defined by the Interactive Advertising Bureau, an industry association.\n\nChoose between the six Template Presets (.yui-t1 through .yui-t6) by setting the class value on the document-wrapping div established in Step 1. Most frequently I use yui-t3, which puts the narrow secondary block on the left and makes it 300px wide. \n\n\n\t
\n\n\nThe Template Presets control two \u201cblocks\u201d of content, which are defined by two divs, each with yui-b (\u201cb\u201d for \u201cblock\u201d) class values. Template Presets describe the width and orientation of the secondary block; the main block will take up the rest of the space.\n\n\n\t\n\n\nUse a wrapping div with an ID of yui-main to structurally indicate which block is the main block. This wrapper\u2014not the source order\u2014identifies the main block.\n\n\n\t\n\n\nExample: Main and secondary blocks sized and oriented with .yui-t3 Template Preset\n\nAgain, regardless of what values you choose in the other steps, you can always toggle between these Template Presets by toggling the class value of your document-wrapping div. It\u2019s really that simple.\n\nStep 3: Nest and Stack Grid Structures.\n\nThe bulk of the power of the system is in this third step. The key is that columns are built by parents telling children how to behave. By default, two children each consume half of their parent\u2019s area. Put two units inside a grid structure, and they will sit side-by-side, and they will each take up half the space. Nest this structure and two columns become four. Stack them for rows of columns.\n\nAn Even Number of Columns\n\nThe default behavior creates two evenly-distributed columns. It\u2019s easy. Define one parent grid with .yui-g (\u201cg\u201d for grid) and two child units with .yui-u (\u201cu\u201d for unit). The code looks like this:\n\n\n\nBe sure to indicate the \u201cfirst\u201c unit because the :first-child pseudo-class selector isn\u2019t supported across all A-grade browsers. It\u2019s unfortunate we need to add this, but luckily it\u2019s not out of place in the markup layer since it is structural information.\n\nExample: Two evenly-distributed columns in the main content block\n\nAn Odd Number of Columns\n\nThe default system does not work for an odd number of columns without using the included \u201cSpecial Grids\u201d classes. To create three evenly distributed columns, use the \u201cyui-gb\u201c Special Grid:\n\n\n\nExample: Three evenly distributed columns in the main content block\n\nUneven Column Distribution\n\nSpecial Grids are also used for unevenly distributed column widths. For example, .yui-ge tells the first unit (column) to take up 75% of the parent\u2019s space and the other unit to take just 25%.\n\n\n\nExample: Two columns in the main content block split 75%-25%\n\nPutting It All Together\n\nStart with a full-width fluid page (div#doc3). Make the secondary block 180px wide on the right (div.yui-t4). Create three rows of columns: Three evenly distributed columns in the first row (div.yui-gb), two uneven columns (66%-33%) in the second row (div.yui-gc), and two evenly distributed columns in the thrid row.\n\n\n\t\n\t\n\t\t\n\t\t

Play the animation \n\nThis could be rewritten by removing the onclick attribute, and instead doing the following from within your JavaScript.\n\ndocument.getElementById('anim-link').onclick = playAnimation;\n\nIt\u2019s all in the timing\n\nOf course, it\u2019s never quite that easy. To be able to attach that onclick, the element you\u2019re targeting has to exist in the page, and the page has to have finished loading for the DOM to be available. This is where the onload event is handy, as it fires once everything has finished loading. Common practise is to have a function called something like init() (short for initialise) that sets up all these event handlers as soon as the page is ready.\n\nBack in the day we would have used the onload attibute on the element to do this, but of course what we really want is:\n\nwindow.onload = init;\n\nAs an interesting side note, we\u2019re using init here rather than init() so that the function is assigned to the event. If we used the parentheses, the init function would have been run at that moment, and the result of running the function (rather than the function itself) would be assigned to the event. Subtle, but important.\n\nAs is becoming apparent, nothing is ever simple, and we can\u2019t just go around assigning our initialisation function to window.onload. What if we\u2019re using other scripts in the page that might also want to listen out for that event? Whichever script got there last would overwrite everything that came before it. To manage this, we need a script that checks for any existing event handlers, and adds the new handler to it. Most of the JavaScript libraries have their own systems for doing this. If you\u2019re not using a library, Simon Willison has a good stand-alone example\n\nfunction addLoadEvent(func) {\n\tvar oldonload = window.onload;\n\tif (typeof window.onload != 'function') {\n\t\twindow.onload = func;\n\t} else {\n\t\twindow.onload = function() {\n\t\t\tif (oldonload) {\n\t\t\t\toldonload();\n\t\t\t}\n\t\t\tfunc();\n\t\t}\n\t}\n}\n\nObviously this is just a toe in the events model\u2019s complex waters. Some good further reading is PPK\u2019s Introduction to Events.\n\nCarving out your own space\n\nAnother problem that rears its ugly head when combining multiple scripts on a single page is that of making sure that the scripts don\u2019t conflict. One big part of that is ensuring that no two scripts are trying to create functions or variables with the same names. Reusing a name in JavaScript just over-writes whatever was there before it.\n\nWhen you create a function in JavaScript, you\u2019ll be familiar with doing something like this.\n\nfunction foo() {\n\t... goodness ...\n}\n\nThis is actually just creating a variable called foo and assigning a function to it. It\u2019s essentially the same as the following.\n\nvar foo = function() {\n\t... goodness ...\n}\n\nThis name foo is by default created in what\u2019s known as the \u2018global namespace\u2019 \u2013 the general pool of variables within the page. You can quickly see that if two scripts use foo as a name, they will conflict because they\u2019re both creating those variables in the global namespace.\n\nA good solution to this problem is to add just one name into the global namespace, make that one item either a function or an object, and then add everything else you need inside that. This takes advantage of JavaScript\u2019s variable scoping to contain you mess and stop it interfering with anyone else.\n\nCreating An Object\n\nSay I was wanting to write a bunch of functions specifically for using on a site called \u2018Foo Online\u2019. I\u2019d want to create my own object with a name I think is likely to be unique to me.\n\nvar FOOONLINE = {};\n\nWe can then start assigning functions are variables to it like so:\n\nFOOONLINE.message = 'Merry Christmas!';\nFOOONLINE.showMessage = function() {\n\talert(this.message);\n};\n\nCalling FOOONLINE.showMessage() in this example would alert out our seasonal greeting. The exact same thing could also be expressed in the following way, using the object literal syntax.\n\nvar FOOONLINE = {\n\tmessage: 'Merry Christmas!',\n\tshowMessage: function() {\n\t\talert(this.message);\n\t}\n};\n\nCreating A Function to Create An Object\n\nWe can extend this idea bit further by using a function that we run in place to return an object. The end result is the same, but this time we can use closures to give us something like private methods and properties of our object.\n\nvar FOOONLINE = function(){\n\tvar message = 'Merry Christmas!';\n\treturn {\n\t\tshowMessage: function(){\n\t\t\talert(message);\n\t\t}\n\t}\n}();\n\nThere are two important things to note here. The first is the parentheses at the end of line 10. Just as we saw earlier, this runs the function in place and causes its result to be assigned. In this case the result of our function is the object that is returned at line 4.\n\nThe second important thing to note is the use of the var keyword on line 2. This ensures that the message variable is created inside the scope of the function and not in the global namespace. Because of the way closure works (which if you\u2019re not familiar with, just suspend your disbelief for a moment) that message variable is visible to everything inside the function but not outside. Trying to read FOOONLINE.message from the page would return undefined.\n\nThis is useful for simulating the concept of private class methods and properties that exist in other programming languages. I like to take the approach of making everything private unless I know it\u2019s going to be needed from outside, as it makes the interface into your code a lot clearer for someone else to read. \n\nAll Change, Please\n\nSo that was just a whistle-stop tour of a couple of the bigger changes that can help to make your scripts better page citizens. I hope it makes useful Sunday reading, but obviously this is only the tip of the iceberg when it comes to designing modular, reusable code.\n\nFor some, this is all familiar ground already. If that\u2019s the case, I encourage you to perhaps submit a comment with any useful resources you\u2019ve found that might help others get up to speed. Ultimately it\u2019s in all of our interests to make sure that all our JavaScript interoperates well \u2013 share your tips.", "year": "2006", "author": "Drew McLellan", "author_slug": "drewmclellan", "published": "2006-12-10T00:00:00+00:00", "url": "https://24ways.org/2006/writing-responsible-javascript/", "topic": "code"}
{"rowid": 123, "title": "Fast and Simple Usability Testing", "contents": "Everyone knows by now that they should test the usability of their applications, but still hardly anybody actually does it. In this article I\u2019ll share some tips I\u2019ve picked up for doing usability tests quickly and effectively.\n\nRelatively recent tools like Django and Ruby on Rails allow us to develop projects faster and to make significant changes later in the project timeline. Usability testing methods should now be adapted to fit this modern approach to development.\n\nWhen to test\n\nIn an ideal world usability tests would be carried out frequently from an early stage of the project. Time and budget constraints lead this to be impractical; usability is often the first thing to get dropped from the project plan.\n\nIf you can only test at one stage in the project, whatever the size, the most valuable time is before your first public beta \u2014 leaving long enough to fix issues and not so late that you can\u2019t rethink your scope.\n\nThere are three main categories of usability test:\n\n\n\tTesting design mockups\n\tTesting a new working application\n\tTesting established applications\n\n\nEach category requires a slightly different approach. For small modern web projects you are most likely to be testing a new working application. You will of course have already done functional tests so you won\u2019t be worried about the user breaking things. The main differences between the categories apply in how you word The Script.\n\nTesting an established application is the most fun in my opinion. Humans are remarkably adaptable and rapidly develop coping strategies to work around usability issues in software they are forced to use. Uncovering these strategies may lead you to understand previously unspoken needs of your users. Often small changes to the application will have a dramatic affect on their everyday lives.\n\nWho to test\n\nWhen you have built a project to scratch your own itch, your intended audience will be people just like you. Test subjects in this case should be easy to find \u2013 friends, co-workers etc.\n\nThis is not always the case; your users may not be like you at all. When they are not, it\u2019s all the more important to run usability tests. Testing on friends, family and co-workers is better than not doing usability tests at all, but it can\u2019t be compared to testing on actual samples of your intended audience. People who would use the system will provide more genuine feedback and deeper insight.\n\nNever let your test subjects put themselves in the shoes of your \u2018actual\u2019 users. For example, you should discourage comments like \u201cWell, I would do this BUT if I was a bus driver I\u2019d do that\u201d. Users are not qualified to put themselves in the position of others. Inaccurate data is often worse than no data.\n\nAim for five or six test subjects: any more and you probably won\u2019t learn anything new; any less and you\u2019re likely to be overwhelmed by issues stemming from people\u2019s individual personalities.\n\nThe Script\n\nThe Script is a single side of A4 (or letter) paper, consisting of questions for your testers and reminders for yourself. Have a balance of task-based questions and expectation analysis. This helps maintain consistency across tests. Expectation analysis is more important for testing designs and new applications: \u201cWhere would you find X?\u201d, \u201cWhat would you expect to happen if you clicked on Y?\u201d. In an established system users will probably know where these things are though it can still be illuminating to ask these questions though phrased slightly differently.\n\nTask-based questions involve providing a task for the user to complete. If you are testing an established system it is a good idea to ask users to bring in tasks that they would normally perform. This is because the user will be more invested in the outcome of the task and will behave in a more realistic fashion. When designing tasks for new systems and designs ensure you only provide loose task details for the same reason. Don\u2019t tell testers to enter \u201cChantelle\u201d; have them use their own name instead. Avoid introducing bias with the way questions are phrased.\n\nIt\u2019s a good idea to ask for users\u2019 first impressions at the beginning of the test, especially when testing design mockups. \u201cWhat are the main elements on the page?\u201d or \u201cWhat strikes you first?\u201d.\n\nYou script should run for a maximum of 45 minutes. 30-35 minutes is better; after this you are likely to lose their attention. Tests on established systems can take longer as there is more to learn from them. When scheduling the test you will need to leave yourself 5 minutes between each one to collate your notes and prepare for the next. Be sure to run through the script beforehand.\n\nYour script should be flexible. It is possible that during the test a trend will come to light that opens up whole new avenues of possible questioning. For example, during one initial test of an established system I noticed that the test subject had been printing off items from the application and placing them in a folder in date order (the system ordered alphabetically). I changed the script to ask future participants in that run, if they ever used external tools to help them with tasks within the system. This revealed a number of interesting issues that otherwise would not have been found.\n\nRunning the tests\n\nTreat your test subjects like hedgehogs. Depending on your target audience they probably feel a little nervous and perhaps even scared of you. So make them a little nest out of straw, stroke their prickles and give them some cat food. Alternatively, reassure them that you are testing the system and that they can\u2019t give a wrong answer. Reward them with a doughnut or jam tart at the end. Try to ensure the test environment is relaxed and quiet, but also as close as possible to the situation where they would actually use the system.\n\nHave your subjects talk out loud is very important as you can\u2019t read their minds, but it is a very unnatural process. To loosen up your subjects and get them talking in the way you want them to, try the Stapler Trick. Give them a stapler or similar item and ask them to open it, take the staples out, replace them, shut the stapler and staple some paper \u2013 talking all the time about what they see, what they expect to happen, what actually happens and how that matches up. Make them laugh at you.\n\nSay how long the test will take up front, and tell your subject why you are doing it. After the test has been completed, conclude by thanking them for their time and assuring them that they were very useful. Then give them the sugary treat.\n\nWhat to look for\n\nPrimarily, you should look out for incidents where the user stops concentrating on her tasks and starts thinking about the tool and how she is going to use it. For example, when you are hammering in a nail you don\u2019t think about how to use a hammer; good software should be the same. Words like \u2018it\u2019 and \u2018the system\u2019 and are good indications that the test subject has stopped thinking about the task in hand. Note questioning words, especially where testers question their own judgement, \u201cwhy can\u2019t I find \u2026\u201d, \u201cI expected to see \u2026\u201d etc. as this indicates that the work flow for the task may have broken down.\n\nAlso keep an eye on occasions where the user completely fails to do a task. They may need some prompting to unstick them, but you should be careful not to bias the test. These should be the highest priority issues for you to fix. If users recover from getting stuck, make a note of how they recovered. Prolonged periods of silence from the test subject may also require prompting as they should be talking all the time. Ask them what they are thinking or looking for but avoid words like \u2018try\u2019 (e.g. \u2018what are you trying to do?\u2019) as this implies that they are currently failing.\n\nBe wary of users\u2019 opinions on aesthetics and be prepared to bring them back to the script if they get side-tracked.\n\nWriting it up\n\nEven if you are the only developer it\u2019s important to summarise the key issues that emerged during testing: your notes won\u2019t make much sense to you a week or so after the test.\n\nIf you are writing for other people, include a summary no longer than two pages; this can consist of a list or table of the issues including recommendations and their priorities. Remember to anonymise the users in the report. In team situations, you may be surprised at how many people are interested in the results of the usability test even if it doesn\u2019t relate directly to something that they can fix.\n\nTo conclude\u2026\n\nSome usability testing is better than none at all, even for small projects or those with strict deadlines. Make the most of the time and resources available. Choose your users carefully, make them comfortable, summarise your report and don\u2019t forget to leave a doughnut for yourself!", "year": "2006", "author": "Natalie Downe", "author_slug": "nataliedowne", "published": "2006-12-16T00:00:00+00:00", "url": "https://24ways.org/2006/fast-and-simple-usability-testing/", "topic": "process"}
{"rowid": 122, "title": "A Message To You, Rudy - CSS Production Notes", "contents": "When more than one designer or developer work together on coding an XHTML/CSS template, there are several ways to make collaboration effective. Some prefer to comment their code, leaving a trail of bread-crumbs for their co-workers to follow. Others use accompanying files that contain their working notes or communicate via Basecamp.\n\nFor this year\u2019s 24ways I wanted to share a technique that I has been effective at Stuff and Nonsense; one that unfortunately did not make it into the final draft of Transcending CSS. This technique, CSS production notes, places your page production notes in one convenient place within an XHTML document and uses nothing more than meaningful markup and CSS.\n\nLet\u2019s start with the basics; a conversation between a group of people. In the absence of notes or conversation elements in XHTML you need to make an XHTML compound that will effectively add meaning to the conversation between designers and developers. As each person speaks, you have two elements right there to describe what has been said and who has spoken: and its cite attribute. \n\n \n\tThis project will use XHTML1.0 Strict, CSS2.1 and all that malarkey.
\n \n\nWith more than one person speaking, you need to establish a temporal order for the conversation. Once again, the element to do just that is already there in XHTML; the humble ordered list.\n\n\n\t\n\t\t \n\t\t\tThis project will use XHTML1.0 Strict, CSS2.1 and all that malarkey.
\n\t\t \n\t \n\t\n\t\t \n\t\t\tThose bits are simple and bulletproof.
\n\t\t \n\t \n \n\nAdding a new note is as simple as adding a new item to list, and if you prefer to add more information to each note, such as the date or time that the note was written, go right ahead. Place your note list at the bottom of the source order of your document, right before the closing tag. One advantage of this approach over using conventional comments in your code is that all the notes are unobtrusive and are grouped together in one place, rather than being spread throughout your document.\n\nBasic CSS styling\n\nFor the first stage you are going to add some basic styling to the notes area, starting with the ordered list. For this design I am basing the look and feel on an instant messenger window.\n\n\n\nol#notes {\n\twidth : 300px; \n\theight : 320px; \n\tpadding : .5em 0; \n\tbackground : url(im.png) repeat; \n\tborder : 1px solid #333; \n\tborder-bottom-width : 2px; \n\t-moz-border-radius : 6px; /* Will not validate */\n\tcolor : #000; \n\toverflow : auto; \n}\nol#notes li { \n\tmargin : .5em; \n\tpadding : 10px 0 5px; \n\tbackground-color : #fff; \n\tborder : 1px solid #666; \n\t-moz-border-radius : 6px; /* Will not validate */ \n}\nol#notes blockquote { \n\tmargin : 0; \n\tpadding : 0; \n}\nol#notes p { \n\tmargin : 0 20px .75em;\n\tpadding : 0; \n}\nol#notes p.date { \n\tfont-size : 92%;\n\tcolor : #666; \n\ttext-transform : uppercase; \n}\n\nTake a gander at the first example.\n\nYou could stop right there, but without seeing who has left the note, there is little context. So next, extract the name of the commenter from the \u2019s cite attribute and display it before each note by using generated content.\n\nol#notes blockquote:before { \n\tcontent : \" \"attr(cite)\" said: \"; \n\tmargin-left : 20px; \n\tfont-weight : bold; \n}\n\nFun with more detailed styling\n\nNow, with all of the information and basic styling in place, it\u2019s time to have some fun with some more detailed styling to spruce up your notes. Let\u2019s start by adding an icon for each person, once again based on their cite. First, all of the first paragraphs of a \u2019s that includes a cite attribute are given common styles.\n\nol#notes blockquote[cite] p:first-child {\n\tmin-height : 34px;\n\tpadding-left : 40px; \n}\n\nFollowed by an individual background-image.\n\nol#notes blockquote[cite=\"Andy\"] p:first-child { \n\tbackground : url(malarkey.png) no-repeat 5px 5px; \n} \n\nIf you prefer a little more interactivity, add a :hover state to each and perhaps highlight the most recent comment.\n\nol#notes blockquote:hover { \n\tbackground-color : #faf8eb; \n\tborder-top : 1px solid #fff; \n\tborder-bottom : 1px solid #333; \n}\nol#notes li:last-child blockquote { \n\tbackground-color : #f1efe2; \n}\n\n\n\nYou could also adjust the style for each comment based on the department that the person works in, for example:\n\n\n\t \n\t\tThis project will use XHTML1.0 Strict, CSS2.1 and all that malarkey.
\n\t \n \n\n\t \n\t\tThose bits are simple and bulletproof.
\n\t \n \nol#notes blockquote.designer { border-color : #600; }\n\nTake a look at the results of the second stage.\n\nShow and hide the notes using CSS positioning\n\nWith your notes now dressed in their finest, it is time to tuck them away above the top of your working XHTML/CSS prototype so that you can reveal them when you need them, no JavaScript required. Start by moving the ordered list of notes off the top of the viewport leaving only a few pixels in view. It is also a good idea to make them semi-transparent by using the opacity property for browsers that have implemented it.\n\nol#notes { \n\tposition : absolute; \n\topacity : .25;\n\tz-index : 2000; \n\ttop : -305px; \n\tleft : 20px; \n}\n\nYour last step is to add :hover and :focus dynamic pseudo-classes to reposition the list at the top of the viewport and restore full opacity to display them in their full glory when needed.\n\nol#notes:hover, ol#notes:focus {\n\ttop : 0; \n\topacity : 1; \n}\n\n\n\nNow it\u2019s time to sit back, pour yourself a long drink and bask in the glory of the final result. Your notes are all stored in one handy place at the bottom of your document rather than being spread around your code. When your templates are complete, simply dive straight to the bottom and pull out the notes.\n\nA Message To You, Rudy\n\nThank-you to everybody for making this a really great year for web standards.

{"rowid": 121, "title": "Hide And Seek in The Head", "contents": "If you want your JavaScript-enhanced pages to remain accessible and understandable to scripted and noscript users alike, you have to think before you code. Which functionalities are required (ie. should work without JavaScript)? Which ones are merely nice-to-have (ie. can be scripted)? You should only start creating the site when you\u2019ve taken these decisions.\n\nSpecial HTML elements\n\nOnce you have a clear idea of what will work with and without JavaScript, you\u2019ll likely find that you need a few HTML elements for the noscript version only.\n\nTake this example: A form has a nifty bit of Ajax that automatically and silently sends a request once the user enters something in a form field. However, in order to preserve accessibility, the user should also be able to submit the form normally. So the form should have a submit button in noscript browsers, but not when the browser supports sufficient JavaScript.\n\nSince the button is meant for noscript browsers, it must be hard-coded in the HTML:\n\n
