title: Size of div tags with an image - html5 with JQuery Mobile
body: <p>I use this statement to get a background image inside the div tag. </p>
  
  <pre><code> &lt;div data-role="content" data-theme="a" style= "height:100%; background:url    
  ('./images/tankanzeige.png') center center no-repeat"&gt;  
  &lt;/div&gt;
  </code></pre>
  
  <p>I want to have the div be the same size as the image, but it has the wrong size it shows only 20% percent of the image.</p>
  
  <p>What do I have to change?</p>
