Random notes on web development:

use em not px - em scales with font size

YUI's CSS foundation has really dumb identifiers - sure, i know the t in yui-t2 stands for template, but how am I supposed to remember it's 180px on the left? Why not call it yui-template-180-left? The rest of the YUI library is really really verbose and typespaced so I don't understand it.

Firebug is your friend.

IE sucks

jQuery is awesome

that is all
