When you mouseover the links (in the red text) a little bubble thing pops up. How was this done? I've looked at the source code, but can't seem to figure it out. Thanks :)

Ah, as I thought... Sweet Titles (http://www.dustindiaz.com/sweet-titles).
Things like that (fading etc.) can only be done with JavaScript, so you should also go more into detail than just looking at the source code.

You should also start using more descriptive titles per our Posting Guidelines (http://codingforums.com/postguide.htm). Titles like these kill the forum searches.
