标签页（tab）切换的jquery实现
标签页（tab）切换的`jquery`实现
说明：
效果其实和原生js实现是一样的。
因为我想写一下jquery代码练练手，所以只是把原生js实现中的js代码改成jquery的形式。

标签页（tab）切换的bootstrap实现
标签页（tab）切换的`bootstrap`实现
说明：
代码中不需要js额外写，只需引用jquery和bootstrap文件即可。
虽然不需要写js，但是缺点是需要点击，并且鼠标离开后回复原状，解决这些问题的话需要写js。
虽然bootstrap看起来很华丽，而且很简便。但是在一些小改动上面很麻烦，而且会踩很多坑。所以如果需要细致并且频繁修改网站的话，建议不用bootstrap搭建网站。
踩坑记录：box-sizing属性的content-box和border-box（其实这也是盒模型的基本）。
