Dave Shea recently published an article on A List Apart (ALA), CSS Sprites2 – It’s JavaScript Time’, about how to use jQuery to create the effect of animated rollovers on navigation items.
The technique he outlines makes use of the same image replacement method as outlined in ALA’s original Sprites article. The problem with this method however is that it uses a large negative text-indent to remove the default text from screen, and with images turned off in the browser, you don’t see anything. This has accessibility implications not only from the perspective of those with disabilities, but also for those who deliberately turn images off, i.e. people on slower connections or those using handheld devices who are trying to limit the amount of information downloaded to their phone.
