一、下载

--bs

  ---css

    ----bootstrap.css

    ----bootstrap.min.css

  ---fonts

  ---js

    ----bootstrap.js

    ----jquery.js

    ----bootstrap.min.js

二、使用

引入css,js文件

 <script src="bs/js/jquery.js"></script>
  <script src="bs/js/bootstrap.js"></script>
  <script src="bs/js/docs.min.js"></script>

三、特点

  1、移动端优先 @media(min-width:  960px)

  2、布局容器 container

  3、栅格系统   1140px分成12份

  4、列偏移

  5、holder.js <img src="holder.js/100%x200" alt="">

  6、优先级   若自己写的css文件和bootstrap的css文件标签和样式重名,但是想先用自己的css样式,在后面加  !important,如:

 .row{
            margin-top: 20px!important;
        }
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <link rel="stylesheet" href="bs/css/bootstrap.css">
    <script src="bs/js/jquery.js"></script>
    <script src="bs/js/bootstrap.js"></script>
    <script src="bs/js/docs.min.js"></script>
    <style>
        .row{
            margin-top: 20px;
        }
    </style>
</head>
<body>
    <div class="container">
        <div class="row">
            <div class="col-md-4">
                <img src="holder.js/100%x200" alt="">
            </div>

            <div class="col-md-offset-4 col-md-4">
                <img src="holder.js/100%x200" alt="">
            </div>
        </div>
        <div class="row">
            <div class="col-md-6">
                <img src="holder.js/100%x200" alt="">
            </div>

            <div class="col-md-6">
                <img src="holder.js/100%x200" alt="">
