I seem to have a problem customizing the Twenty Eleven theme. I would like that the top header above the header image to have a background color that goes from side to side in the window. Found out that the problem may come from max-width set to 1000px, but could not find where to put it so it doesn't mess up the theme elsewhere.
How can I achieve to have a color on the top of the page (ex. like facebook top blue header) that has the width of the browser?
