          </style>
    		
       </head>
    	
       <body>
          <div>
    		
             <ul>
                <li class="above">list item 0</li>
                <li class="top">list item 1</li>
                <li class="top">list item 2</li>
                <li class="middle">list item 3</li>
                <li class="middle">list item 4</li>

                <li class="top">list item 1</li>
                <li class="selected">list item 2</li>
                <li class="selected">list item 3</li>
                <li class="selected">list item 4</li>
                <li class="bottom">list item 5</li>
                <li class="bottom">list item 6</li>
