I didn't add many styles to this example menu. Its purpose is to demonstrate
the use of display:table-cell; (and the work-around for IE5-7) to
center the items in a horizontal menu.
It works in IE5+/Win, Firefox, Netscape 7+, Opera 8+, Safari 1.2+ (I've heard that it would probably work in 1.1 as well), Konqueror 3.3+, IE5/Mac, and iCab 3.
