title: Div class only in one page via jQuery
body: <p>I've got a class:</p>
  
  <pre><code>.sample {
      background:url("../sample.png") repeat-x scroll 0 0 transparent;
      height:200px;
      position:absolute;
      top:0;
      width:100%!important;
      z-index:101
  }
  </code></pre>
  
  <p>This is a mask and I want to use this class to be called in one page and not all the pages. How can i do?</p>
