Site is badly broken in ie8.

user: ogs

Can someone please explain to me the major things that ie does not render correctly. Is there a "main" culprit? I use a lot of floats, are they rendered differently in ie? Is it simple padding/margins that are different?

I do use some CSS3 properties but those are for gradients/rounded corners. Not so much for layout.

In the meantime doing some research, thanks guys!
