[Technology] HTML5, CSS, and the web of the future

So, I've been a bit too busy with my Masters to keep up with all the neat innovations happening everywhere, but Google has a recent blog post talking about some new stuff that Chrome is supporting, and I'm delighted by two of them.



Templates

Basically, you can include a snippet of HTML that won't be displayed; that way, the rest of your page can make use of it later when it wants to.  So, for example, I might build a table in JavaScript, but I don't want to define the HTML for the rows in the JavaScript (because it's a bit clunky that way), so I get to write it naturally inside the template, and then just query for the row's template later, customise it, clone it, and append it.  Yay.



In fact, I already basically do this by including elements whose display is set to hidden, so I guess this just more formal.
