向列表组添加自定义内容
我们可以向上面已添加链接的列表组添加任意的 HTML 内容。下面的实例演示了这点：
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title>Bootstrap历练实例：向列表组添加内容</title>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width,initial-scale=1.0" />
<link rel="stylesheet" href="bootstrap-3.3.5-dist/css/bootstrap.min.css" />
</head>
<body>
<div style="padding:20px">
<div class="list-group">
<a href="#" class="list-group-item active" ><h2 class="list-group-item-heading">Html5</h2></a>
<a href="#" class="list-group-item"><h2 class="list-group-item-heading">Css3</h2><p class="list-group-item-text">Css3是html5前端必学的技术</p></a>
</div>
</div>
<script src="jQuery/jquery-2.1.4.js"></script>
<script src="bootstrap-3.3.5-dist/js/bootstrap.min.js"></script>
</body>
</html>
