 一、起步

1、简介

Bootstrap 是最受欢迎的 HTML、CSS 和 JS 框架，用于开发响应式布局、移动设备优先的 WEB 项目。

　Bootstrap它是基于jQuery，也就意味着你在用bootstrap要先导入jQuery文件

为所有开发者、所有应用场景而设计。
Bootstrap 让前端开发更快速、简单。
所有开发者都能快速上手、所有设备都可以适配、所有项目都适用。

2、下载

 

二、全局css样式

1、布局容器

<div class="container "></div>          左右有固定留白
<div class="container-fluid c1"></div>  全屏展示
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <script src="https://cdn.bootcss.com/jquery/3.4.1/jquery.min.js"></script>
    <link rel="stylesheet" href="bootstrap-3.3.7/css/bootstrap.min.css">
    <script src="bootstrap-3.3.7/js/bootstrap.min.js"></script>

    <style>
        .c1 {background-color: red;height: 1000px;}
    </style>
</head>
<body>
<div class="container-fluid c1"></div>
<div class="container c1"></div>
</body>
</html>

 

2、栅格系统

栅格系统用于通过一系列的行（row）与列（column）的组合来创建页面布局

　　一个row就表示一行(这一行默认给你均分成了12份,每一份你还可以均分成12份)
　　首先使用bootstrap先写一个布局容器
　　　　<div class=\’container\’></div>
　　　　<div class=\’container-fluid\’></div>
　　语法：
　　　　<div class=”container”>
　　　　<div class=”row”> 一行
　　　　<div class=”col-md-6 c1″></div> 控制你占当前行的多少列

借助谷歌浏览器自动切换手机或电脑屏幕，只需要加一个col-xs-6生成对应的布局
    <style>
        .c1 {
            background-color: red;
            height: 50px;
            border: 3px solid black;
        }
        @media screen and (max-width: 600px) {
            .c1 {
            background-color: green;
            height: 50px;
            border: 3px solid black;
        }
        }
    </style>
</head>
<body>
<div class="container">
    <div class="row">
        <div class="col-md-6 col-xs-6 c1"></div>
        <div class="col-md-6 col-xs-6 c1"></div>
        <br>
        <div class="col-md-3 c1"></div>
        <div class="col-md-9 c1"></div>
        <br>
        <div class="col-md-1 c1">
            <div class="row">
                <div class="col-md-6 c1"></div>
                <div class="col-md-6 c1"></div>
            </div>
        </div>
    </div>
</div>
</body>
</html>

 3、列偏移

    <style>
         .c1 {
            background-color: red;
            height: 50px;
            border: 3px solid black;
        }
    </style>
</head>
<body>
<div class="container">
    <div class="row">
        <div class="col-md-6 c1 col-md-offset-3">
        <!--<div class="col-md-6 c1 pull-right">-->  <!--右飘-->
    </div>
</div>

</body>
</html>

4、排版

<body>
<div class="container">
    <div class="row">
        <div class="col-md-6 col-md-offset-3">
            <h1>虹桥校区脱产七期最牛逼!<small>确实牛逼</small></h1>
        </div>
</div>
</body>
