IE7 background and li issue

Hey everyone,
I am having issues with my website in IE7:

The background is not displaying properly and the suckerfish dropdown menu under “Books” on the topnav is not showing the list of items properly either.

Any help in resolving these issues greatly appreciated.

I tried changing the doctype to XHTML 1.1

<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.1//EN””>
<html xmlns=“” xml:lang=“en” >

But it still did not fix anything in IE7.
Any ideas?

HTML 5 and CSS 3 does not support by IE7

Try the same CSS with XHTML1.1 or HTML4 it will work in all browsers.
