Bootstrap 轮播（Carousel）插件是一种灵活的响应式的向站点添加滑块的方式。除此之外，内容也是足够灵活的，可以是图像、内嵌框架、视频或者其他您想要放置的任何类型的内容。如果您想要单独引用该插件的功能，那么您需要引用 carousel.js,或者bootstrap.js 或压缩版的 bootstrap.min.js。

data格式的Url最直接的好处是，这些Url原本会引起一个新的网络访问，因为那里是一个网页的地址，现在不会有新的网络访问了，因为现在这里是网页的内容。这样做，会减少服务器的负载，当然同时也增加了当前网页的大小。所以对“小”数据特别有好处。详细了解见本栏Bootstrap中的data讲解（http://blog.youkuaiyun.com/boonyaxnn/article/details/64441413）
