title: CSS background:url() on external server
body: <p>I am using the following css rule:</p>
  
  <pre><code>background: url("http://example.com/background.jpg");
  </code></pre>
  
  <p>It is not working and I suppose it is because referring to external servers is not supported. Is this true? If so, what kind of workaround I might use?</p>
  
  <p>Not sure if it's relevant, but I need this inline. Testing right now on JSFiddle.</p>
