Someone has been in a situation like this? I bet it
As said in Best Practices for Building Web Applications, one of the things to have in mind when developing Web Applications (or any simple HTML website) is to Think on Semantics. Let's see how this can boost our websites and raise them to the top.
While developing a web application, I often need to reload a whole site for every change I do in its CSS file, only to test it. Under Firefox I used to change manually the href in links (well, in fact, with Firebug) to add some query string, in order to by-pass the cache and request the brand-new version of the file. This job was often harder than that, since I'm still maintaining some old school applications using frames (Eek!).
While writing my jQuerify Bookmarklet I thought this CSS refresher is the perfect job for a bookmarklet, so I ended writting the CSS Refresh Bookmarklet.
If there's something I've learned during my developer life, is to make a list of basic rules and to be faithful to them. These rules are the skeleton on which all my own applications shall be built. Of course, these rules also evolved as time goes by, growing stronger or falling into obsolescence, often unpredictably.
Web development is not different from C++ coding, so it also has its own ruleset in order to avoid "bad habits". These are my rules, tell me yours.
Update:Now returns the resulting <object> on success
I was in need of some simple Javascript to add SWF objects. Hoping for a simple, cross-browser, ie-proof, eolas-respectful and graceful-degradable solution is a difficult praise to attend, so I began, as always, to write my own.
The routine is so simple because it does nothing more than add a <object> tag so it can embed the flash movie. No plugin or software checks. I didn't need them.
Maybe it's my fault, maybe not. The truth is that I had some problems optimizing my webserver load with CSS Sprites, a nice, clean technique to max the efficiency of every image. Let's go into details:
I used a set of flag icons (taken from Fam fam fam) in a site admin zone. There are 247 flags, sweet and small (16x11) and that's all I needed. In this admin you can browse through tables with tons of data, to the point that all of the flags may be shown at once. More than once, in fact. So in a clean-cached browser you probably end requesting 247 images from the server. Even if the only answer were a 304 Not modified (in another scenario) they're too many requests. No way, being the "optimizer" I am, I need to change that.
Oh, floats. Every web designer have worked with them. Floats let you rearrange the flow of elements. They're powerful, they're useful, they're... painly buggy on old browsers, I know. But they're one of the CSS2 most used properties, so they deserve some respect.
Let's make some fun with floats. We will design a simple menu from nothing more than pure HTML tags and some CSS magic.
