【2020Python修炼记】前端开发之 前端框架Bootstrap
一、简介
该框架已经帮你写好了很多页面样式，你如果需要使用，只需要下载它对应文件，之后直接cv拷贝即可
在使用Bootstrap的时候所有的页面样式都只需要你通过class来调节即可
版本选择建议使用v3版本：https://v3.bootcss.com/
【注意】
bootstrap的js代码是依赖于jQuery的，也就意味着你在开发项目时，使用Bootstrap动态效果的时候，一定要导入jQuery。
方法一： 利用CDN 导入（需要有网络才可以）
<head> …… <link href="https://cdn.bootcss.com/twitter-bootstrap/3.4.1/css/bootstrap.min.css" rel="stylesheet"> <script src="https://cdn.bootcss.com/jquery/3.3.1/jquery.min.js"></script> <script src="https://cdn.bootcss.com/twitter-bootstrap/3.4.1/js/bootstrap.min.js"></script> …… </head>方法二：下载文件到本地，将文件夹加入所在项目中，直接引用--例如 引入 弹框插件
<link rel="stylesheet" href="bootstrap-sweetalert-master/dist/sweetalert.css"> <script src="bootstrap-sweetalert-master/dist/sweetalert.min.js"></script>【注意】
导入CSS 文件 使用 <link rel="stylesheet" href=" CSS 文件路径 ">
导入 JS 文件 使用 <script src=" js 文件路径 / CDN地址 "></script>
二、特色框架功能
布局容器
<div class="container">
左右两侧有留白
</div>
<div class="container-fluid">
左右两侧没有留白
</div>
# 后续在使用bootstrap做页面的时候 上来先写一个div class=container,之后在div内部书写页面

栅格系统
<div class="row"></div> 写一个row 就是将所在的区域划分成 12 份 <div class="col-md-6 "> 获取你所要的份数 # 在使用bootstrap的时候 脑子里面一定要做12的加减法
栅格参数
.col-xs- .col-sm- .col-md- .col-lg- # 针对不同的显示器 bootstrap会自动选择对应的参数 # 如果你想要兼容所有的显示器 你就全部加上即可 # 在一行如何移动位置 <div class="col-md-8 c1 col-md-offset-2"></div>

排版
bootstrap将所有原生的HTML标签的文本字体统一设置成了肉眼可以接受的样式
效果一样，但是标签表达的意思不一样（语义）
