title: Is it a good practice using an animated gif as CSS sprites?
body: <p>I have a website that pops-up animated icons when you <code>mouseover</code> them</p>
  <p>But i think that maybe it could result in poor graphical performance from the browser. I could put animated icons in a sprite, and not-animated icons in another, but what is the point? in that way sprites stop being useful. Do you recommend using a script that animate the icons placed in the sprite manually?
  What is your recommendation? Since i need a good performance.</p>
