<p>下载 <strong>Bootstrap v4.6.2</strong> 的即用即用的编译代码，轻松集成到你的项目中，包括：</p>
<ul>
<li>编译和压缩的 CSS 包（参见
<a href="/docs/4.6/getting-started/contents/#css-files">CSS 文件对比</a>）</li>
<li>编译和压缩的 JavaScript 插件（参见

</p>
<h2 id="source-files">源文件</h2>
<p>通过下载我们的源 Sass、JavaScript 和文档文件，使用你自己的资产流水线编译 Bootstrap。此选项需要一些额外的工具：</p>
<ul>
<li>
<a href="/docs/4.6/getting-started/build-tools/#sass">Sass 编译器</a> 用于将 Sass 源文件编译为 CSS 文件</li>
<li>
<a href="https://github.com/postcss/autoprefixer">Autoprefixer</a> 用于 CSS 厂商前缀</li>
