title: Imitate CSS3 transition in IE?
body: <p>I'm using a combination of rules to achieve the CSS3 <code>transition</code> rule in as cross-browser compatible a way as possible: I'm using <code>transition</code>, <code>-webkit-transition</code>, <code>-moz-transition</code>, and <code>-o-transition</code>.</p>
  
  <p>Is there a similar <code>-ms-transition</code> 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?</p>
  
  <pre><code>/* IE 8 */ 
  -ms-filter: "progid:DXImageTransform.Microsoft. Alpha(Opacity=50)"; 
  /* IE 5-7 */ 
  filter: alpha(opacity=50);
  </code></pre>
