Forum Moderators: not2easy
I agree that it's almost never a good idea to try anyway, but I have a couple sites where hover brings in a subtly animated background image on the anchor element. That can be rather effective without being troublesome, IMO. That's why I was disappointed with the lack of support in Opera.
But all things considered, it's probably a wise move on their part.
Can it be done without using CSS
Sure - just plug in the animated gif wherever you would normally put the background image - no special assembly required.
