What's the IE's problem?

[Anakib]

Hello everybody,
I just finnished a very basic CSS template for a school project, but unfortunately IE don't like my CSS 2 rule set. I tried to keep everything simple, both the markup and the CSS (without any hacks), because I really want something easy and straightforward...

Any ideas or tips? This is a common IE problem, because I 've never face it before.

Thank you.
