    一、 响应式介绍

    - 响应式布局是什么?
            同一个网页在不同的终端上呈现不同的布局等
    - 响应式怎么实现的?
            1. CSS3 media query 媒体查询
            2. JS去控制网页的布局和样式等
                - 缺点:工作量大,网页响应慢
                - 优点: 专治疑难杂症
            3. 用框架
                - Bootstrap       响应式工具

      $(document).ready(function () {

      });
    </script>

    响应式练习

    二、Bootstrap补充
        - 在使用响应式的时候  要加上两个meta标签 

    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1">

        - modal   模态框
        - 轮播     
        - collapse
        - tooltip
     - Togglable tabs     tab切换


        - 自定义Bootstrap组件,
            - 找到自定义那一页
            - 勾选我用到的组件
            - 拉到最后面,点击下载

    三、常用插件

    ## 常用jQuery插件
    
      - [Font Awesome](http://fontawesome.io/)     字体图标
      - [jQuery lazy load](https://github.com/tuupola/jquery_lazyload)     懒加载图片
      - [SweetAlert](https://github.com/t4t5/sweetalert)/[SweetAlert2](https://github.com/limonte/sweetalert2)   弹出框
      - [Toastr](http://codeseven.github.io/toastr/)     通知栏

        使用:
          基本上都是基于jQuery
          1. 先导入插件的CSS文件
          2. 导入jQuery
          3. 导入插件的JS文件

    四、常用插件示例
