Question

I am using LESSCSS. I\'m trying to create a method for opacity:

{
    opacity: @opacity;
    -ms-filter: \"progid:DXImageTransform.Microsof         


        

Answer 1

There is nice solution I found in internet - LESS CSS class for cross browser opacity:

.opacity(@opacity) {

     @ieOpacity: @opacity * 100;
     -ms-filter: ~"progid:DXImageTransform.Microsoft.Alpha(Opacity=@{ieOpacity})"; // IE 8
     filter: ~"alpha(opacity=@{ieOpacity})"; // IE 5-7
     opacity: @opacity;
}
