I have a header class which has a background and a header-center class which provides the nav content for the header. My problem is that if the window is smaller than the header-center width, the header background doesn't span the entire top when you scroll over. Stackoverflow seems to have the same problem, try resizing it and you'll see what I mean - they gray background doesn't expand over to the search box. How would I go about fixing this? Thanks!
A:
if the background is inside a container with a width of 100% and any parent container, including the <body> or <html> don't have a width set in the CSS then you will experience this behaviour. as 100% will be 100% of the browser viewport. Change this to a fixed width and it should stretch to fill the fixed width.
