I have been working for hours to make the header fit the browser width, but I can't figure out how to do it. The final result must look like this

I hope that someone can help me to fix this problem.

forum URL please ...

I'm coding it locally...

I try to explain better the problem. I'd like to use a big image as header, but I don't know how to make it fit the browser width.

well, we do not suggest to use a large image for the logo !
in general a 960px width image should fit well for any site

lets wait for an expert to provide precise suggestion ...
