Transparent PNG animate problem on Internet Explorer

Question

CSS Code:

#btn{
  background: url(transparent.png) no-repeat;
  filter: alpha(opacity=0);
  -moz-opacity: 0;
  -khtml-opacity: 0;
  opacity: 0;
}
         


        

Answer 1

There is a library that supposedly solves this problem: jCSML. I have tried it and it works to animate transparent pngs in IE 7+.
