【2020-01-06】Bootstrap从入门到放弃（一）——入门

一、快速入门

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
    <link rel="stylesheet" href="../static/css/bootstrap.min.css">
    <title>首页</title>
</head>

<body>
    <h1>Hello, world!</h1>

    <script src="../static/js/jquery-3.4.1.min.js"></script>
    <script src="../static/js/popper.min.js"></script>
    <script src="../static/js/bootstrap.min.js"></script>
  
</body>

</html>

Bootstrap优先适配移动端，必须在<head>中声明

<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

CSS和JS的依赖

<link rel="stylesheet" href="../static/css/bootstrap.min.css">

<script src="../static/js/jquery-3.4.1.min.js"></script>
<script src="../static/js/popper.min.js"></script>
<script src="../static/js/bootstrap.min.js"></script>
