Bootstrap

Bootstrap:

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。


2. 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>

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。

CSS样式和JS插件

1. 全局CSS样式:
	* 按钮:
		* class="btn btn-default" 默认样式
		* class="btn btn-primary" 首选项
		* class="btn btn-success" 成功
		* class="btn btn-info" 一般信息
		* class="btn btn-warning" 警告
		* class="btn btn-danger" 危险
		* class="btn btn-link" 链接
	* 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
		* 给表格项添加:class="table" 
		* table-bordered 为表格和其中的每个单元格增加边框
		* table-hover 通过添加 .table-hover 类可以让 <tbody> 中的每一行对鼠标悬停状态作出响应。
	* 表单
		* 给表单项添加:class="form-control" 
2. 组件:
	* 导航条			
	* 分页条
3. 插件:
	* 轮播图
