Bootstrap：
-
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：
- 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。
- 响应式布局。
- 同一套页面可以兼容不同分辨率的设备。
-
快速入门
- 下载Bootstrap
- 在项目中将这三个文件夹复制
- 创建html页面，引入必要的资源文件
- 下载Bootstrap
- 最基础框架代码

响应式布局
- 同一套页面可以兼容不同分辨率的设备。
- 全屏网页效果
- 将网页缩小将会自动适应
-
实现：依赖于栅格系统：将一行平均分成12个格子，可以指定元素占几个格子
-
步骤：
- 定义容器。相当于之前的table、
- 容器分类：
- container：两边留白
- container-fluid：每一种设备都是100%宽度
- 容器分类：
- 定义行。相当于之前的tr 样式：row
- 定义元素。指定该元素在不同的设备上，所占的格子数目。样式：col-设备代号-格子数目
- 设备代号：
- xs：超小屏幕 手机 (<768px)：col-xs-12
- sm：小屏幕 平板 (≥768px)
- md：中等屏幕 桌面显示器 (≥992px)
- lg：大屏幕 大桌面显示器 (≥1200px)
- 设备代号：
- 注意：
- 一行中如果格子数目超过12，则超出部分自动换行。
- 栅格类属性可以向上兼容。栅格类适用于与屏幕宽度大于或等于分界点大小的设备。
- 如果真实设备宽度小于了设置栅格类属性的设备代码的最小值，会一个元素沾满一整行。
- 定义容器。相当于之前的table、

CSS样式和JS插件
1. 全局CSS样式：
1. 按钮：class=“btn btn-default”
代码
<a class="btn btn-default" href="#" >Linka>
