I doubt this is part of the problem but you also might not see the animation if you are using an older browser. Some animations were added on later so older browsers don't recognize them.

I don't know of any sources that explicitly lead to pure CSS hover animations because if you understand how to use CSS animations, the hovering aspect is rather insignificant. Here is a list of the CSS things that may be relevant to your situation.
 * animation property
 * keyframes rule
 * transition property
 * transform property
