Still nothing? Really?
Please, is it so difficult? Where am I wrong?
Thank you very much!

Try to be more specific, maybe then someone understand your issue and can help.
The CSS seems fine for me, no errors.
And when your issue is with colors, this is a matter of taste and you have to be even more specific what's wrong.
