title: Random background images CSS3
body: <p>I am doing small website, however I have like 5-6 images for my background, and I want to make it random every time I refresh the page. This is what I got in style.css :</p>
  
  <pre><code>html {   
      background:  url(image/l2.jpg) no-repeat center center fixed
      -webkit-background-size: cover
      -moz-background-size: cover
      -o-background-size: cover
      background-size: cover   
  }
  </code></pre>
