Ok, so I would do the CSS rule I posted above.

But I wouldn’t really recommend putting a custom px for the width of the header, because you can make the header fit nicely on your current browser, and computer screen width, but as soon as you go to a new computer with different screen widths, the header will not stretch across the entire screen because you have specified it to be a specific width.

You don’t even need to specify the “width” in the theme, just make sure you have:

`position: relative;`
