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。
查看 Bootstrap教程。
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/3.3.4/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/3.3.4/css/bootstrap.min.css\">
以下是一个完整的 HTML 实例, 使用了 AngularJS 指令和 Bootstrap 类。
