title: Remove background when modal pops up
body: <p>I am using jQuery CustomBox modal and all works fine. However, I am trying to ‘hide’ the content div behind the modal once popped up. I then want the content div to reappear again after the modal has closed. Here is the working example:</p>

  <p>I have just been watching the jQuery videos from css-tricks but still having problems trying to get this to work :) Any help is much appreciated!</p>
  
  <p>EDIT: I want to content div to reappear when the modal is closed via outside the modal screen as well as the actual 'x' button.</p>
  
  <p>EDIT: the actual web page is <a href="http://www.akboheim.com/tsc/new.html" rel="nofollow">here</a></p>
  
  <p>Click on ‘CLICK ME’ and you can see the modal pops up fine, however, I’d like ONLY the background image of the cellar showing, not the page underneath it.</p>
  
  <p>Any suggestions??
  Thanks!</p>
