Bootstrap 胶囊式标签页
nav 类通用于标签和胶囊（Pills）。
我们可以使用基类 .nav-pills而不是 .nav-tabs创建基础的基于pills的导航，而不需要对标记进行任何进一步的更改。

</ul>

</html>例子
我们可以通过附加一个额外的类nav-stack来垂直堆叠这些pills：

我们可以添加图标到胶囊式导航。

<li><a href="#"><span class="glyphicon glyphicon-envelope"></span> Messages</a></li>
</ul>
</div>
</body>
</html>折叠胶囊式导航
默认情况下胶囊式导航是水平的。要使pills垂直折叠，需在<ul>元素中添加一个额外的类.nav-stacked。

<ul class="nav nav-pills nav-stacked">
<li class="active"><a href="#">Home</a></li>
<li><a href="#">Profile</a></li>
<li><a href="#">Messages</a></li>
</ul>
</div>
</body>
</html>对齐标签和Pills
我们可以通过添加额外的类.nav-justified使标签和胶囊式导航宽度等于其父元素。
它只适用于宽大于768px的屏幕，在较小的屏幕上，导航链接是堆叠的。

</html>禁用Pill组件中的链接
我们可以使用类.disabled让导航中的所有链接显示为禁用。
