title: How do I get background image size in jQuery?
body: <p>The problem is simple. How do I get a div's background image size (width and height) in jQuery. Is it even possible? I thought this would work:</p>
  
  <pre><code>jQuery('#myDiv').css('background-image').height();
  </code></pre>
  
  <p>The error message I get is that this is not a function.</p>
