1. 安装

  • 使用 CDN 引用
代码语言：javascript复制
<link href="https://cdn.jsdelivr.net/npm/bootstrap@5.1.3/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-1BmE4kWBq78iYhFldvKuhfTAU6auU8tT94WrHftjDbrCEXSU1oBoqyl2QvZ6jIW3" crossorigin="anonymous">
<script src="https://cdn.jsdelivr.net/npm/bootstrap@5.1.3/dist/js/bootstrap.bundle.min.js" integrity="sha384-ka7Sk0Gln4gmtz2MlQnikT1wXgYsOg OMhuP IlRH9sENBO0LRn5q 8nbTov4 1p" crossorigin="anonymous"></script>
  • 或者下载 https://getbootstrap.com/

popper.js cdn：https://unpkg.com/@popperjs/core@2 jquery.js https://code.jquery.com/jquery-3.6.0.js

解压 Bootstrap 到项目下，并下载（复制粘贴）上面两个 js 文件到 js 文件夹里

后面使用外部文件引入即可
