向列表组添加徽章
我们可以向任意的列表项添加徽章组件，它会自动定位到右边。只需要在 <li> 元素中添加 <span class="badge"> 即可。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：带徽章的列表组</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">
<ul class="list-group">
<li class="list-group-item">Html5</li>
<li class="list-group-item">Css3</li>
<li class="list-group-item">Bootstrap<span class="badge">3.3.5</span></li>
<li class="list-group-item">Javascript</li>
<li class="list-group-item">jQuery<span class="badge">2.1.4</span></li>
<li class="list-group-item">jQueryUI</li>
<li class="list-group-item">C#.Net</li>
<li class="list-group-item">MsSql</li>
</ul>
</div>
<script src="jQuery/jquery-2.1.4.js"></script>
<script src="bootstrap-3.3.5-dist/js/bootstrap.min.js"></script>
</body>
</html>
