If you need fade animation on hover or such things, CSS3 transition property is your solution.

EDIT:

.btn {
  background-color: lightblue;
  -webkit-transition: all 0.3s ease-out;  /* Saf3.2+, Chrome */
     -moz-transition: all 0.3s ease-out;  /* FF4+ */
      -ms-transition: all 0.3s ease-out;  /* IE10 */
       -o-transition: all 0.3s ease-out;  /* Opera 10.5+ */
          transition: all 0.3s ease-out;
}  

.btn:hover {
  background-color: lightgreen;  
}
