IE Blues

[MrApples]

I just happened as my 'dynamic header' (what I call it) was nearing completion, happened to visit the site using IE and not FireFox. What I saw was a disaster.

Could someone please point me to a guide for making it cross-browser compatible. I only would like to support IE6+ and Opera's latest(whatever that is).

For those of you who are really good at this stuff and are just in the mood of finding obvious errors...
