I'm using a combination of rules to achieve the CSS3 transition rule in as cross-browser compatible a way as possible: I'm using transition, -webkit-transition, -moz-transition, and -o-transition.
Is there a similar -ms-transition property for any version of Internet Explorer? Is there a proprietary filter for older versions of IE, similar to how the following rules work for opacity in IE 6-8?
/* IE 8 */
-ms-filter: "progid:DXImageTransform.Microsoft. Alpha(Opacity=50)";
/* IE 5-7 */
filter: alpha(opacity=50);
