    <div id="tv">

      background:url(../img/tv.png) no-repeat 0 0;
    }
    #bg {
      width:220px; height:180px; position:absolute; left:42px; top:30px;
      z-index:-2; background-color:#000;
    }
    #static {
      width:216px; height:178px; position:absolute; left:44px; top:31px;
      z-index:-1; background:url(../img/static.gif) no-repeat 0 0;
