div alignment Options

[supahstah_luv]

kay well here's a pretty much finished skin that i eventually want to submit, but div alignment is always such a pain T_T it seems to work on my computer (using IE) but apprently it doesn't on other peoples'..

does anyone know how to fix alignment so it's compatible with most browsers?
