title: Display a different background after the load during 5 seconds and then change it definitively
body: <p>I would like to display in the first 5 seconds after loading, a different background every 1 second or a little less. And after these 5 seconds I would like to set a definite background.</p>
  
  <p>I set already the class of my div:</p>
  
  <pre><code>&lt;div id="plateau" class="step01"&gt;
  &lt;div id="plateau-fond"&gt;
  </code></pre>
  
  <p>And I set the background in my CSS:</p>
  
  <pre><code>#plateau.step-01 #plateau-fond
   {
    background-image:url('../img/plateau-03-step-01.png');
   }
  </code></pre>
  
  <p>I would like to use javascript or jQuery to execute as mentioned above.</p>
