CSS Showcase - a gallery of CSS menus
If you need some inspiration for the next time you start working on a menu/tabbed navigation design, Vitaly Friedman's CSS Showcase is the place to go.
The gallery contains screenshots of more than fifty different tabbed menu designs found on live websites, and the number is increasing. Vitaly is also working on making it possible for visitors to submit their own designs for the gallery.
To help visitors who want to implement their own CSS menu, the CSS Showcase also contains an overview of CSS navigation techniques.
While the CSS Showcase doesn't contain anything new or revolutionary, it's nice to have all those examples and techniques in a single place.
