HEy, I want to change my header from this:
to this:
The header goes over full page there and menu, too.
What he means is.. He wants his header (logo & navigation menu) to expan 100%
of his site's width.
He then wants his welcome back, categories, forums and footer around 85% wide.
It's easy. Edit your CSS where it says .head or .header to 100% instead of 85%, 1250 or something similar.
In the .css check that your container width is set to 100% and that there is no padding or border.
If that does not solve it then try adding this.
#container #header {
width: 100%;
}
