title: using jquery to dynamically create div
body: <p>I am trying to add a background image to a dynamically generated div.  When I add the CSS property for the background, like below, it breaks my plugin:</p>
  
  <pre><code>$("&lt;div&gt;", {
      'class': "iviewer_image_mask",
      css: "background: url('http://somesite.com/path/to/image.jpg');"
  }).appendTo(this.container);
  </code></pre>
  
  <p>Anybody know what I am doing wrong to add the background image?</p>
