CSS screwed up

ok so my site (www.majd-gfx.com) almost works on IE and totally messes up on FF. please view my source and help me, i need this

Don't you mean doesn't work on IE, and is displayed exactly as it is coded in Firefox?

If you want it display as you intended then add overflow:auto; to #content

ok thnx a lot that made it better, but the content div is misplaced and it's like an i-frame, i want it to stretch....thnx

EDIT: ok i made some progress but still the sides won't extend for some reason

The fonts for the menu are quite large, but I see that you haven't declared a font size yet, probably why it's larger than the background. It would be best to put those in lists rather than just a div, as it's just more semantic, but it works.
