Question

Is there a way to make a button’s background color change from a color to another on hover with fade effect? I know this can be done in javascript but I’d rather only use css for this.

Answer 1

CSS3 transition property is your solution.

.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;  
}
