html

<div class="container">
        <div id="content1" class="active">列表1内容:123456</div>
        <div id="content2">列表2内容:abcdefgkijkl</div>
        <ul class='nav'>
            <li class="active"><a href="#content1">列表1</a></li>
            <li><a href="#content2">列表2</a></li>
        </ul>
        <div class="wrap"></div>
</div>
