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

Use PNG image for modern Browsers ( mozilla , Opera, Chrome etc ) :

background:url(../images/banner01.png) no-repeat right 13px;

Add this For IE ( Use another CSS Or use IE hack )

/* ie fix */
background-image:none;
filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(src="images/banner01.png",
 sizingMethod="crop");

Answer 2

filter:'' hack does not work with current jQuery (1.6.1) anymore

Answer 3

There is currently no solution for this that I'm aware of. Just have to wait for IE to catch up with the rest of the world. I had to abandon such a feature in a recent project just days ago. You unfortunately cannot have a feathered-edge PNG with IE fading in and out with jQuery.

Answer 4

For me it worked to just include the filter property with blank value in jQuery's .animate()function

Maybe this will work for you, too.

$("#btn").animate({opacity:1,"margin-left":"-25px", filter:''});

Additionally you might have to remove the filter property from your button's CSS.
