I can't get the stylesheet editor to load on that page, but I think this would be a good first step: @media only screen and (max-width:1083px){.WikiaHeader{width:718px}} @media only screen and (min-width:1084px) and (max-width:1595px){.WikiaHeader{width:1024px}} @media only screen and (min-width:1596px){.WikiaHeader{width:1178px}}

This should give your header the same width as the main page background based on the user's screen size. However you will also need to adjust the positioning with a negative left margin for each screen size. margin-left:-20px; seems about right for the last one but you'll need to experiment a bit.
