Funny Formatting in Opera; Not FireFox

Hey guys,

I’m using Dreamweaver to produce a WordPress template. Everything looked great until I opened the site with Google Chrome (and hearing about it on Safari). The footer is hanging out on my sidebar, and the content spacing is all off. I’ve been going crazy trying to figure out what’s wrong with the formatting to produce different elements with Chrome.

If anyone could lend some possibilities I would most appreciate it.

Thanks!
