title: Fancybox Overlay Opacity
body: <p>I am using the fancybox plugin version 2.0.6</p>
  
  <p>I am trying to change the overlay opacity as detailed in the documentation, but can't get it to work. Can anyone advise on how I might be doing this wrong.</p>
  
  <p>Thanks.</p>
  
  <p>Here's what I have:</p>
  
  <pre><code>    $(function () {
          $(".fancybox")
          .attr('rel', 'gallery')
          .fancybox({
              padding : 0,
              margin : 0,
              arrows: false,
              closeBtn: false,
              closeClick: true,
              openEffect : 'none',
              openSpeed : 100,
              closeEffect : 'none',
              closeSpeed : 100,
                  helpers : {
                      title : null,
                      speedIn: 0,
                      speedOut: 0,
                      opacity: 0.8,
                  }
              });
          });
  </code></pre>
