一、一个小知识点

1、截取长屏的操作

Bootstrap补充

2、设置默认格式

Bootstrap补充

3、md,sm, xs

Bootstrap补充

4、空格和没有空格的选择器

Bootstrap补充

二、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

测试用css 媒体查询实现响应式

方式一、link.css文件

Bootstrap补充

主文件中导入link.css文件

Bootstrap补充

方式二、link2.css文件

Bootstrap补充

在主文件中导入link2.css文件

用Bootstrap实现的响应式例子

三、常用插件

常用插件基本上都是基于jQuery ,

  先导入插件的CSS文件

  再导入jQuery文件

  最后导入JS,注意jQuery是必须要放在JS上面的

1、Sweet Alert(弹出框)

  使用步骤:1下载 2解压找到里面的dist(主要是dist)和animate.css  3引入到自己的文件里就行了
注:如果是html参数就要用animate

<script src="sweetalert2/sweetalert2.min.js"></script> <script>
// swal({
// title: '你真的确定吗?',
// text: "当前操作是删库,可能你需要回去收拾一下行李,准备跑路。。。",
// type: 'warning',
// showCancelButton: true,
// confirmButtonColor: '#3085d6',
// cancelButtonColor: '#d33',
// confirmButtonText: '是的,我准备好离职了!',
// cancelButtonText: '是的,我准备好离职了!'
// // 点击确认按钮后,执行这个then
// }).then(function () {
// // 做逻辑判断
// console.log("做逻辑判断...");
// swal(
// '删除成功!',
// '留给你的时间不多了',
// 'success'
// )
// }) // swal({
// title: 'Sweet!',
// text: 'Modal with a custom image.',
// imageUrl: 'z.png',
// imageWidth: 400,
// imageHeight: 200,
// imageAlt: 'Custom image',
// animation: false
// })
</script> </body>

五、需要知道的几个插件网址

1、SweetAlert (弹出框):https://github.com/t4t5/sweetalert

   2、SweetAlert2 (弹出框):https://github.com/limonte/sweetalert2

   3、Font Awesome(字体图标):http://fontawesome.io

4、jQuery lazy load(懒加载):https://github.com/tuupola/jquery_lazyload

5、Toastr(通知栏):http://codeseven.github.io/toastr/

六、Bootstrap网址:http://v3.bootcss.com/

有时间看一下这个网址:http://www.jq22.com/daima

七、自定义Bootstrap组件,

    1、找到自定义那一页

    2、勾选我用到的组件
    3、拉到最后面,点击下载

八、Bootstrap补充:

   - modal
   和模态框使用的
   $("#myModal").modal("show")
  - collapse :也是在JavaScript组件中去找,点击按钮有信息出来

   - tooltip : 相当于提示信息,就像是一个按钮,指向按钮会有提示信息
