      return false;
      }
  &lt;/script&gt;
  &lt;style&gt; html .fb_share_button { 
     display: -moz-inline-block; 
     display:inline-block;
     padding:1px 20px 0 5px; 
     height:15px;
     border:1px solid #d8dfea;
     background:url(http://static.ak.facebook.com/images/share/facebook_share_icon.gif?6:26981) no-repeat top right;
   } 
  html .fb_share_button:hover {
      color:#fff;
