I have a header graphic 700 px in width which has red at one end and blue at the other, inside a resizable header.
I want to set the header image in the center of the page but I want the extra space either side of the header image to fill in with red one side and blue the other, so that when the page is extended there is no gap etc.
I am sure it must be easy but I cannot get my head round it at present.
Anyone got any ideas how I can achieve this
