title: how to center horizontally the li elements
body: <p>I am using domtab on my <a href="http://exerion.comule.com/prochaine.html" rel="nofollow">site</a>, but for some reasons I can't center the li elements  (the ones with ver1, ver2, TOUS LES FILMS, AFFICHAGE HORAIRE, ... written in them) or the ul block.</p>
  
  <p>Here is the code relative to the domtab:</p>
  
  <pre><code>   #domtab_main{  
          width:600px;  
          margin:20px auto; position:relative;  
  
  
  
          /*height: 100px;*/
      }
  
      ul.domtabs{
          position: relative;
          /*float:left;*/
          /*width:100%;*/
          width: 600px;   
          /*margin : 0 auto;*/
          /*padding-left: 110px;*/    
          font-family: MS Courier New;
          font-size: 17px;    
          /*padding:0;*/
          /*text-align:center;*/
  
  
          padding: 0px;
          /*list-style: none;*/
          margin-right: auto;
          margin-left: auto;
          margin-top: 0px;
          margin-bottom: 0px;
          left: auto;
  
      }
      ul.domtabs li{
          list-style:none;
          float:left;
          padding:0 .5em 0 0;
      }
  
  
      ul.domtabs a:link,
      ul.domtabs a:visited,
      ul.domtabs a:active,
      ul.domtabs a:hover{
          /*width: 170px;*/
          padding:10px;
          display:block;
          /*background:#666;
          color:#ccc;*/
          height:3em;
          /*font-weight:bold;*/
          text-decoration:none;
  
          color:#f0f0f0;  
        background: -moz-linear-gradient(top, #117586 0%, #158CA1 100%);
        background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#117586), color-stop(100%,#158CA1));
        background: -webkit-linear-gradient(top, #117586 0%,#158CA1 100%);
        background: -o-linear-gradient(top, #117586 0%,#158CA1 100%);
        background: -ms-linear-gradient(top, #117586 0%,#158CA1 100%);
        background: linear-gradient(top, #117586 0%,#158CA1 100%);
        filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#117586', endColorstr='#158CA1',GradientType=0 );
  
  
      }
  
  
      div.domtab div{
          clear:both;
          width:auto;
          /*background:#696;*/
          color:#000;
          padding:1em 3em;
          padding-bottom: 0;
      }
  </code></pre>
