I'm testing some coding I found at http://css-tricks.com/snippets/css/c...owser-opacity/ to add an transparent overlay to a website. It seems to be working fine with firefox. But in IE 8 it doesn't seem to work, the bar seems to be all black.

Anyone who can help me out here?

ps. I hope this coding is cross browser, I've searched a long time for it.

-ms-filter: “alpha(opacity=75)”; /* ie 8 */
-ms-filter:”progid:DXImageTransform.Microsoft.Alpha(Opacity=75)”; // first
filter: alpha(opacity=75); // second
