CSSplay has put together a list of 15 professional looking horizontal based CSS menus. The menus use the sliding door technique so that each menu item will fit the associated text. The menus use professional grade graphics and since they use CSS, it wouldn’t be hard for you to customize these menus for your own needs. Here are a few samples.
Check out the entire list of 15 which are free for download. When your finished, come back and let us know which one was your favorite.
