Javascript or CSS?

CSS

Css, i seen a tutorial that used css and sprites for the roll over images and it was really cool.

I suggest you to always use css in order to do image rollovers :
- clean , easy to do, less code

BUT you have to pay a little attention because there should be incompatibilities with some browsers, so you must make some extra test... but the results are great and professional.

If do you need some help I suggest you this tutorial :

Not really. Even IE6 will do a simple css rollover w/o issues.

CSS is the best solution. It will support all browsers. Some of the Browser block the scripts.

I will choose css.css+html is the best solution

CSS would be the best.

tables and images and javascript.

Oh wait, it's 2010. Try CSS.

I will go with the Ed-way. please spare the javascript, use CSS. and yes IE6 will go along CSS way.

CSS is best for rollover
