title: Change the background color of Fancybox
body: <p>I want to make the background color of Fancybox transparent. </p>
  
  <p>The obvious way is to use ".fancybox-skin" in your CSS, but this will affect all fancyboxes, and I need it to vary. Thus the setting needs to be sent with wrapCSS.</p>
  
  <p>Fancybox has a parameter "wrapCSS" that can be passed in with the original js call, but I'm not sure how to use it. It just says "string": <a href="http://fancyapps.com/fancybox/#useful" rel="nofollow">http://fancyapps.com/fancybox/#useful</a></p>
  
  <p>I've been trying to pass in the CSS like <code>{wrapCSS: "background: red"}</code>, but it's not working.</p>
