Overlay transparency for IE8

[aseemk]

Hey, just wondering, any reason you used opacity: 1 and background: rgba(0,0,0,.75) in overlay.css instead of a solid black background and 0.75 opacity? Adding filter: alpha(opacity=75) would allow it to then work in IE8 with no seeming downside for modern browsers.

no specific reason, I'd be fine with changing that. I'm ok with bits and pieces to support >IE8 and friends, just nothing huge and unwieldy

Great. The change was simple:

#overlay {
   position: fixed;
   top: 0;
   left: 0;
-  opacity: 1;
+  opacity: 0.75;
+  filter: alpha(opacity=75);
   width: 100%;
   height: 100%;
-  background: rgba(0,0,0,.75);
+  background: black;
   transition: opacity 300ms;
   z-index: 500;
 }
