AngularJS Bootstrap

AngularJS 的首选样式表是 Twitter Bootstrap， Twitter Bootstrap 是目前最受欢迎的前端框架。

Bootstrap

你可以在你的 AngularJS 应用中加入 Twitter Bootstrap，你可以在你的 <head>元素中添加如下代码:

<link rel="stylesheet" href="//maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.min.css">

如果站点在国内，建议使用百度静态资源库的Bootstrap，代码如下：

<link rel="stylesheet" href="//apps.bdimg.com/libs/bootstrap/3.2.0/css/bootstrap.min.css">

以下是一个完整的 HTML 实例, 使用了 AngularJS 指令和 Bootstrap 类。
