I like it a lot. Your css looks to be fine. Nothing omitted, no wrong code.

Only one critique (that's me, and it's not meant to be negative!!!): why choose 10px for a font-size?
You have good eyes and you can read small text, probably even on a 1600x1200 screen. But it does become very small. Some people may have set their default to 14px because their sight isn't that sharp anymore. For these it becomes unreadable.

BTW: you know about Firefox's developer toolbar? Great and free little tool when you're designing sites.

This said, your design is really great. Conscise, to the point and clear.
Great work!
