今天学习了一下Bootstrap框架，，写一个小实例练练手，感受一下bootstrap兼容三端的强大。

虽然有两三百行代码，但是写起来也就二十分钟的事情，不得不说bootstrap真是又方便又强大！
看一下界面效果吧~~~~
设计得不咋好看，主要目的还是练习一下bootstrap的使用。
一个导航条，下面是一个轮播图，导航条是始终保持在顶部的。
下面是一个栅格，里面的文字就偷懒没写了~~~
整体看上去是这样：
再下面是一个标签页，做得也比较简洁
还有一些小功能，例如点击按钮会出现下拉框、模态框什么的，这里就不多记录了。
总之，以往纯CSS需要花费几天几夜的项目，使用bootstrap十几分钟就完成了。
学无止境，我们一直在路上。
