title: How to read a browser's unsupported CSS properties?
body: <p>Quite by accident today, I discovered that in IE6, IE7 and IE8 it is possible to read unsupported CSS properties using the .css() method of jQuery:</p>
  
  <pre><code>jQuery(node).css('transition');   // Returns the transition value 
  </code></pre>
  
  <p>This allowed me to add an animation fallback for CSS3 transitions to these browsers in my jQuery plugin jquery.transitions (<a href="http://github.com/stephband/jquery.transitions" rel="noreferrer" title="jquery.transitions">github.com/stephband/jquery.transitions</a>). Joy.</p>
  
  <p>The question is: is it possible to read unsupported CSS properties in other browsers? My initial tests using the above method in FF3.6 and IE9 were fruitless. Is there another way, short of parsing the stylesheets?</p>
