BootStrap学习 Day1: 栅格系统/ 样式 / 插件 / 组件 / 旅游网案例（代码多为框架内复制使用）
Bootstrap
1.1 BootStrap概述
1. 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。
1.2 BootStrap快速入门
. 快速入门
1. 下载Bootstrap
2. 在项目中将这三个文件夹复制
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">
<!-- 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。 -->
<script src="js/bootstrap.min.js"></script>
</head>
<body>
<h1>你好，世界！</h1>
</body>
</html>
1.3 BootStrap_栅格系统入门
## 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：
1. container：两边留白
2. container-fluid：每一种设备都是100%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。样式：col-设备代号-格子数目
* 设备代号：
1. xs：超小屏幕 手机 (<768px)：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，会一个元素沾满一整行。
