How to check if css box-shadow is supported (jQuery)?

Question

I\'m creating a layout in full css. However, some browser (such as IE6) do not support box-shadow (.. and -webkit-box-shadow or -moz-box-shadow). I would like to check if it

A neat function (pure JavaScript, no jQuery) to check which CSS features are supported by the browser is described in Quick Tip: Detect CSS3 Support in Browsers with JavaScript.

Function is as follows:

var supports = (function() {
   var div = document.createElement('div'),
      vendors = 'Khtml Ms O Moz Webkit'.split(' '),
      len = vendors.length;

   return function(prop) {
      if (prop in div.style) {
          return true;
      }

      prop = prop.replace(/^[a-z]/, function(val) {
         return val.toUpperCase();
      });

      while (len--) {
         if (vendors[len] + prop in div.style) {
            // browser supports box-shadow. Do what you need.
            // Or use a bang (!) to test if the browser doesn't.
            return true;
         } 
      }

      return false;
   };
})();

Usage is like this:

if (supports('boxShadow')) { 
   // Do whatever
}

It worked like a charm for me! :-)
