An experiment to use CSS for image rollovers in lieu of JavaScript. As of today (October 3, 2001), it works in Internet Explorer 5.5+ and Mozilla 0.9.4. In Internet Explorer 5 and 6, it sometimes doesn't perform as quickly as JavaScript would though it easily out-performs JavaScript in Mozilla 0.9.4. This was a recent Mozilla fix because it did not work in 0.9.3.
