I'm doing some tests with new features of CSS3, but this combination only works in lastest versions of Chrome and Firefox, but not in Safari or Opera:
box-shadow: inset 0px -10px 20px 0px rgba(0, 0, 0, 0.5);
-webkit-box-shadow: inset 0px -10px 20px 0px rgba(0, 0, 0, 0.5);
-moz-box-shadow: inset 0px -10px 20px 0px rgba(0, 0, 0, 0.5);
I really don't know if they fails in the box-shadow itself, in the inset parameter, or in RGBA color. It's a syntax error or simply Safari and Opera lacks on this?
