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

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


        

Answer 1

naaa .. this one worked for me:

.opacity(@a:0.5){
    zoom:1;
    opacity: @a;
    -moz-opacity: @a;
    @iea : @a*100;
    -ms-filter: ~"progid:DXImageTransform.Microsoft.Alpha(opacity=(@{iea}))";
    filter:~"alpha(opacity= @{iea})";
}
