I've got a design that I'm working on and all my layouts are working fine in Chrome, FF, and Safari. IE 8 is behaving, but when switching on compatibility mode it breaks and it does not render correctly in Opera 10 either. I use a CSS reset to standardize everything (I know some folks here hate that) but it's not correcting the problems in those two browsers.
It seems like a positioning and margin problem. Here is the site if you wouldn't mind taking a look and offering a little feedback.
I'm still in the development stage for this site, so it may be a bit messy, but I'd appreciate any input or help.
