body: <p>Is there a better way then using <a href="http://api.jquery.com/jQuery.browser/" rel="nofollow noreferrer">jQuery.browser</a>, or <a href="http://www.quirksmode.org/js/detect.html" rel="nofollow noreferrer">equivalents</a>, for determining <a href="http://www.quirksmode.org/css/boxshadow.html" rel="nofollow noreferrer">css 3</a> prefixes (-moz, -webkit, etc), as <a href="http://www.quirksmode.org/js/detect.html" rel="nofollow noreferrer">it is disencouraged</a>? Since the css is dynamic (the user can do anything with it on runtime), css hacks and style tag hacks can't be considered.</p>
