概念：
一个前端开发的框架，Bootstrap，来自 Twitter，是目前很受欢迎的前端框架。Bootstrap 是基于 HTML、CSS、JavaScript 的，它简洁灵活，使得 Web 开发更加快捷。 * 框架:一个半成品软件，开发人员可以在框架基础上，在进行开发，简化编码。 * 好处： 1. 定义了很多的css样式和js插件。我们开发人员直接可以使用这些样式和插件得到丰富的页面效果。 2. 响应式布局。 * 同一套页面可以兼容不同分辨率的设备。
目录
快速入门：
环境设置：
一.导入下载的bootstrap工具包
1.解压下载的bootstrap工具包
2.复制解压后的bootstrap-3.3.7-dist中的三个文件夹到项目中，文件夹如下图。
复制到项目之后，如下图。
资源引入模板：
环境设置完之后，bootstrap的文件算是初步导入到项目中了。但是在每次使用的时候都需要引入资源才能使用。所以为了不每次都去导入资源，下面写了个模板。方便每次使用的时候直接复制模板，然后改模板
就可以了。

这个只是bootstrap封装的一部分css代码，还又很多css样式。就不一 一在这展示了。展示一个只是为了告诉大家，其实很多css代码不需要自己完全手写。可以借助框架来完成，而且框架的代码还可以进行修改。前提是你得能看懂代码，所以不要只依赖这些封装好的框架。更多全局css样式 ，只要用到了知道在那查就基本可以入门了。
组件：
这里只展示两个组件，分页条和导航条。其他和全局css样式一样，更多组件请点击查看。
