bootStrap_笔记
## 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"
  * 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
   * 给表单项添加：class="form-control"
 2. 组件：
  * 导航条
  * 分页条
 3. 插件：
  * 轮播图
