So, to update, I tried in IE but nothing works there at all. That is no round corners, no linear gradient (but can wait for IE10, although I tested in Windows Internet Explorer Platform Preview but nothing), margins are off and my box-shadow doesn't work either:

box-shadow:10px 12px 35px 1px rgba(10, 10, 10, 1);
-moz-box-shadow:10px 12px 35px 1px rgba(10, 10, 10, 1);
-webkit-box-shadow:10px 12px 35px 1px rgba(10, 10, 10, 1);


These work in firefox and opera anyway.
