Question

In order to create interactive fake 3D animation as on this site:

Or those interactive animations on Apples iPad features page (halfway down):

What is faster, CSS Sprites or imgs?

(At least semantically, using img makes more sense I think.)

Answer 1

If your are using vector shapes that sprite is better but if your are using images like this car pic's, mountain pic's etc. Then sperate images (IMG Tag) are better.

SO, if you are using images then <img> is perform better then sprite.
