javascript rollover造句

What are the pros and cons of CSS rollover buttons vs Javascript rollover buttons?
In my current project I have javascript rollovers which only implement if the browser is explorer for this reason, but I only did that after it became clear that IE was giving me flack.
Javascript rollovers should be a bit more supported in general, simply because javascript support is better in general, but all of the current versions of major browsers can do both, to my knowledge.
If you use javascript rollovers, you run into a problem with javascript compatability and the new trend of disabling javascript .-- ( talk ) 03 : 07, 29 January 2007 ( UTC)
