So this: @media screen and has(renderer:Trident) { a.exlink {display:inline-block;} } can be rewritten as @media screen and support( display, inline-block ) { a.exlink {display:inline-block;} } @else { a.exlink {display:block; } } This construction will match IE6, IE7, Opera but not FF2 as IE and Opera do have support of inline-block. (IE supports it partially, only for <span> alike elements, but still) I believe that modular architecture of CSS3 implies that UA may support CSS3 partially - on per-module basis at least. Thus support() may help web technologies to evolve gradually and more rapidly than now. Andrew Fedoniouk http://terrainformatica.com
