title: Background-size: cover property with Windows Phone browser
body: <p>I'm trying to use the <code>background-size: cover</code> property. It works everywhere but .. on windows phone ! (I tried with a HTC 8X)</p>
  
  <pre><code>body.menu{
      background: url('[my_picture_link]') no-repeat top center fixed;
      -webkit-background-size: cover;
      -moz-background-size: cover;
      -o-background-size: cover;
      background-size: cover;
      min-height: 100%;
  }
  </code></pre>
  
  <p>Any idea to fix it?</p>
