Now you can write HTML and CSS lightning-fast!

Zen coding is a new, shorter way of writing HTML/CSS. It's basically a collection of snippets that you use through writing simple syntaxes.

Here's an example for HTML :

ul#name>li.item*3

provides

<ul id="name">
    <li class="item"></li>
    <li class="item"></li>
    <li class="item"></li>
</ul>

and similary for CSS:

bdrz:w

provides

-webkit-border-radius:; 

These are just two simple examples, visit http://mondaybynoon.com/2009/08/17/the-art-of-zen-coding-bringing-snippets-to-a-new-level/ for more information.

I should mention that this is a plugin for your IDE. Currently it supports NetBeans, Coda, Texmate and Aptana. There is no official release for Visual Studio but Einar Egilsson has written his own for Visual Studio.

Happy front-end coding!!
