Forum Change entire expanding header
 

Hi everyone,


I recently purchased a new 4.0 version of the forum. I am looking for some advice please on changing the header. Right now I have replaced the small VBulletin image top left, but would like to incorporate an image and bg image that will stretch accordingly the full width of the forum.

Do I have to change the CSS style sheet and if so where would I find that?

Thank you very much.
