135	135	A Scripting Carol	We all know the stories of the Ghost of Scripting Past – a time when the web was young and littered with nefarious scripting, designed to bestow ultimate control upon the developer, to pollute markup with event handler after event handler, and to entrench advertising in the minds of all that gazed upon her. And so it came to be that JavaScript became a dirty word, thrown out of solutions by many a Scrooge without regard to the enhancements that JavaScript could bring to any web page. JavaScript, as it was, was dead as a door-nail. With the arrival of our core philosophy that all standardistas hold to be true: “separate your concerns – content, presentation and behaviour,” we are in a new era of responsible development the Web Standards Way™. Or are we? Have we learned from the Ghosts of Scripting Past? Or are we now faced with new problems that come with new ways of implementing our solutions? The Ghost of Scripting Past If the Ghost of Scripting Past were with us it would probably say: You must remember your roots and where you came from, and realize the misguided nature of your early attempts for control. That person you see down there, is real and they are the reason you exist in the first place… without them, you are nothing. In many ways we’ve moved beyond the era of control and we do take into account the user, or at least much more so than we used to. Sadly – there is one advantage that old school inline event handlers had where we assigned and reassigned CSS style property values on the fly – we knew that if JavaScript wasn’t supported, the styles wouldn’t be added because we ended up doing them at the same time. If anything, we need to have learned from the past that just because it works for us doesn’t mean it is going to work for anyone else – we need to test more scenarios than ever to observe the multitude of browsing arrangements we’ll observe: CSS on with JavaScript off, CSS off/overridden with JavaScript on, both on, both off/not supported. It is a situation that is ripe for conflict. …	2006	Derek Featherstone	derekfeatherstone	2006-12-21T00:00:00+00:00	https://24ways.org/2006/a-scripting-carol/	code
335	335	Naughty or Nice? CSS Background Images	Web Standards based development involves many things – using semantically sound HTML to provide structure to our documents or web applications, using CSS for presentation and layout, using JavaScript responsibly, and of course, ensuring that all that we do is accessible and interoperable to as many people and user agents as we can. This we understand to be good. And it is good. Except when we don’t clearly think through the full implications of using those techniques. Which often happens when time is short and we need to get things done. Here are some naughty examples of CSS background images with their nicer, more accessible counterparts. Transaction related messages I’m as guilty of this as others (or, perhaps, I’m the only one that has done this, in which case this can serve as my holiday season confessional) We use lovely little icons to show status messages for a transaction to indicate if the action was successful, or was there a warning or error? For example: “Your postal/zip code was not in the correct format.” Notice that we place a nice little icon there, and use background colours and borders to convey a specific message: there was a problem that needs to be fixed. Notice that all of this visual information is now contained in the CSS rules for that div: <div class="error"> <p>Your postal/zip code was not in the correct format.</p> </div> div.error { background: #ffcccc url(../images/error_small.png) no-repeat 5px 4px; color: #900; border-top: 1px solid #c00; border-bottom: 1px solid #c00; padding: 0.25em 0.5em 0.25em 2.5em; font-weight: bold; } Using this approach also makes it very easy to create a div.success and div.warning CSS rules meaning we have less to change in our HTML. Nice, right? No. Naughty. Visual design communicates The CSS is being used to convey very specific information. The choice of icon, the choice of background colour and borders tell us visually that there is something wrong. With the icon as a background image – there…	2005	Derek Featherstone	derekfeatherstone	2005-12-20T00:00:00+00:00	https://24ways.org/2005/naughty-or-nice-css-background-images/	code
