Hacks

• IE8 rgba equivalent

background: #000;
-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=80)";

This doesn't allow clicks to go through transparent element, contrary to filter: progid:DXImageTransform.Microsoft.gradient(startColorstr=#CC000000,endColorstr=#CC000000)

There is also an issue with jQuery and fadeIn/fadeOut method which resets ms filter opacity to (respectively) 100/0.
