Substituting CSS-based techniques for old-style graphic rollovers and DHTML menus is one of the most effective web site optimization techniques available. Graphic rollovers use “on” and “off” graphics to create rollover effects, with and without JavaScript. DHTML menus create nested menu structures with JavaScript, some of it complex. With the widespread adoption of CSS2-aware browsers, there is a better choice: CSS-based techniques. Substituting list-based markup, CSS2 to style, and an optional dash of JavaScript makes for fast, small, and accessible CSS menus.
