Sass mixin for background transparency back to IE8

Question

I\'m new to Sass and struggling with this. I can\'t get the color to render in both hex (for IE) and rgba. Every little piece is frustrating me becau

Answer 1

@mixin transparent($color, $alpha) {
  $rgba: rgba($color, $alpha);
  $ie-hex-str: ie-hex-str($rgba);
  background-color: transparent;
  background-color: $rgba;
  filter:progid:DXImageTransform.Microsoft.gradient(startColorstr=#{$ie-hex-str},endColorstr=#{$ie-hex-str});
  zoom: 1;
}

NOTE: The ie-hex-str is only available in recent versions, not sure when it was introduced though
