BootStrap
# 概念：一个前端开发的框架，来自 Twitter，是目前很受欢迎的前端框架。BootStrap 是基于 HTML、CSS、JavaScript 的，简介灵活，能使得 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的基础上，再进行开发，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
1）下载 BootStrap
2）复制这三个文件夹到项目下
3）创建 html 页面，引入必要的资源文件
<!DOCTYPE html>
<html lang="zh-CN">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">
<!-- 上述3个meta标签*必须*放在最前面，任何其他内容都*必须*跟随其后！ -->
<title>Bootstrap HelloWorld</title>
<!-- Bootstrap -->
<link href="../css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
<!-- jQuery (Bootstrap 的所有 JavaScript 插件都依赖 jQuery，所以必须放在前边) -->
<script src="../js/jquery-3.2.1.min.js"></script>
<!-- 加载 Bootstrap 的所有 JavaScript 插件。你也可以根据需要只加载单个插件。 -->

响应式布局
# 同一套页面可以兼容不同分辨率的设备
# 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：
1）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% 的宽度
2）定义行，相当于之前的 tr 样式：row
3）定义元素，指定该元素在不同的设备上，所占的格子数目，相当于 td。样式：col - 设备代号 - 格子数目
* 设备代号
①：xs：超小屏幕，手机（ < 768px ）如：col - xs - 12
②：sm：小屏幕，平板（ > 768px ）
③：md：中等屏幕，桌面显示器（> 992px）
④：lg：大屏幕，大桌面显示器（> 1200px）
* 注意：
1、一行中如果格子数目超过 12，则超出部分自动换行
2、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像素大小的设备
3、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，一个元素会占满一整行，多个元素会换行展示

css样式 和 JS插件
# 全局 css 样式：
* 按钮：class = "btn btn - default"
* 图片：
* class = "img - responsive"：图片在任意尺寸都占 100%
* 图片形状：
* <img src = "..." alt= "..." class = "img - rounded">：方形
* <img src = "..." alt= "..." class = "img - circle">：圆形
* <img src = "..." alt= "..." class = "img - thumbnail">：相框
* 表格：
* table
* table - bordered
* table - hover
* 表单
* form - control ：给表单项定义
* form - horizontal ：给form标签定义
