At http://www.shieldscompany.com, the main (blue) product menu uses a sprite and has sub-menus. Our programmer set it up so that the sub-menus are relative to the top of the browser, rather than under the sprite. On the site's sub-pages, the sub-menus appear correctly, but on the home page they appear behind a large rotating graphic. Can someone take a look at http://www.shieldscompany.com/css/nav.css and help me understand how to change this so it works properly?
