I'm fairly new to CSS as I'm trying to begin using it to code rather than table-heavy HTML. I'm working on a website an have a drop-down navigation menu that is the center of my problem. In Safari and Firefox, the navigation's menus drop down over everything like they should. In Internet Explorer, however, they get hidden behind the white content box below.

I tried using the validator and there were three problems, but being new to this, I'm not really sure what they are and how to fix them. I would be extremely grateful if anyone could help me out.
Thanks for your time!
