6.Bootstrap框架
Bootstrap介绍
- Bootstrap是Twitter开源的基于HTML、CSS、JavaScript的前端框架。
- 它是为实现快速开发Web应用程序而设计的一套前端工具包。
- 它支持响应式布局，并且在V3版本之后坚持移动设备优先。
- 就是复制黏贴一把梭，html\css\js代码的封装组合

Bootstrap的导入
在head的标签中学
<link href="../bootstrap-3.3.7/css/bootstrap.min.css" rel="stylesheet">
Bootstrap全局样式
排版、按钮、表格、表单、图片等我们常用的HTML元素，Bootstrap中都提供了全局样式
我们只要在基本的HTML元素上通过设置class就能够应用上Bootstrap的样式，从而使我们的页面更美观和谐
基础模板:看结构
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> <link rel="stylesheet" href="../font-awesome/css/font-awesome.css"> <link href="../bootstrap/css/bootstrap.min.css" rel="stylesheet"> </head> <body> <h1>你好，小钱！</h1> <script src="../jquery-3.2.1.min.js"></script> <script src="../bootstrap/js/bootstrap.min.js"></script> <script> </script> </body> </html>
布局容器
container 类用于固定宽度并支持响应式布局的容器。
<div class="container"> ... </div>
container-fluid 类用于 100% 宽度，占据全部视口（viewport）的容器
<div class="container-fluid"> ... </div>
栅格系统
媒体查询
/* 小屏幕（平板，大于等于 768px） */
@media (min-width: @screen-sm-min) { ... }
/* 中等屏幕（桌面显示器，大于等于 992px） */
@media (min-width: @screen-md-min) { ... }
/* 大屏幕（大桌面显示器，大于等于 1200px） */
@media (min-width: @screen-lg-min) { ... }
从堆叠到水平排列
