Do u have any problem with this?

I guess my new website layout done with wordpress is well done about the css…but…
Now i have some problems! :shifty:

For example with the old firefox i see the hr line below the header even if the css says that it should be white! :puzzle:

Do you see any other problem with this css?
What about the footer?

Please let me know! :s:
