</script>
   
<script type="text/javascript" language="javascript">

   $(document).ready(function() {
      /* This would select second division only*/
      $(".big").css("background-color", "yellow");
   });

</script>
</head>
<body>

<div class="big" id="div1">
  <p>This is first division of the DOM.</p>
</div>

</div>
