title: How to hide a background with AdBlock Plus filter
body: <p>Some websites set a background image to advertise, e.g.</p>
  
  <pre><code>&lt;body style="background-image:url('images/adv.png')"&gt;
  </code></pre>
  
  <p>I'm wondering how I can write an AdBlock Plus filter in order to hide the <code>&lt;body&gt;</code> background.</p>
