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。
