title: Fadeout/Darken background behind ModalPopupExtender in ASP
body: <p>I am currently working on a ModalPopupExtender in ASP.net with C#. I have the modal popup extender working fine but I was just wondering if there was a way to darken the background with some sort of animation to make the popup extender more noticeable. </p>
  
  <p>Is there a form of JQuery or AJAX or something that would provide me with this sort of functionality. </p>
  
  <p>Thanks for the help.</p>
