下载

下载 Bootstrap 以获取已编译的 CSS 和 JavaScript、源代码,或将其包含在你最喜欢的包管理器中,例如 npm、RubyGems 等。

编译 CSS 和 JS

¥Compiled CSS and JS

下载 Bootstrap v5.3.3 的即用型编译代码以轻松放入你的项目中,其中包括:

¥Download ready-to-use compiled code for Bootstrap v5.3.3 to easily drop into your project, which includes:

这不包括文档、源文件或任何可选的 JavaScript 依赖(例如 Popper)。

¥This doesn’t include documentation, source files, or any optional JavaScript dependencies like Popper.

源文件

¥Source files

通过下载我们的源 Sass、JavaScript 和文档文件,使用你自己的资源管道编译 Bootstrap。此选项需要一些额外的工具:

¥Compile Bootstrap with your own asset pipeline by downloading our source Sass, JavaScript, and documentation files. This option requires some additional tooling:

如果你需要我们的全套构建工具,它们包含在开发 Bootstrap 及其文档中,但它们可能不适合你自己的目的。

¥Should you require our full set of build tools, they are included for developing Bootstrap and its docs, but they’re likely unsuitable for your own purposes.

通过 jsDelivr 的 CDN

¥CDN via jsDelivr

使用 jsDelivr 跳过下载,将 Bootstrap 编译的 CSS 和 JS 的缓存版本交付到你的项目。

¥Skip the download with jsDelivr to deliver cached version of Bootstrap’s compiled CSS and JS to your project.

<link href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.3/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-QWTKZyjpPEjISv5WaRU9OFeRpok6YctnYmDr5pNlyT2bRjXh0JMhjY6hW+ALEwIH" crossorigin="anonymous">
<script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.3/dist/js/bootstrap.bundle.min.js" integrity="sha384-YvpcrYf0tY3lHB60NNkmXc5s9fDVZLESaAA55NDzOxhy9GkcIdslK1eN7N6jIeHz" crossorigin="anonymous"></script>

如果你使用我们编译的 JavaScript 并且更喜欢单独包含 Popper,请在我们的 JS 之前添加 Popper,最好通过 CDN。

¥If you’re using our compiled JavaScript and prefer to include Popper separately, add Popper before our JS, via a CDN preferably.

<script src="https://cdn.jsdelivr.net/npm/@popperjs/core@2.11.8/dist/umd/popper.min.js" integrity="sha384-I7E8VVD/ismYTF4hNIPjVp/Zjvgyol6VFvRkX/vR+Vc4jQkC+hVqc2pM8ODewa9r" crossorigin="anonymous"></script>

替代的 CDN

¥Alternative CDNs

我们推荐 jsDelivr 并在我们的文档中使用它。但是,在某些情况下(例如在某些特定国家或环境中),你可能需要使用其他 CDN 提供商,例如 cdnjsunpkg

¥We recommend jsDelivr and use it ourselves in our documentation. However, in some cases—like in some specific countries or environments—you may need to use other CDN providers like cdnjs or unpkg.

你会在这些 CDN 提供商上找到相同的文件,尽管 URL 不同。使用 cdnjs,你可以从任何版本的 Bootstrap 中为每个 dist 文件复制并粘贴现成的 HTML 片段。

¥You’ll find the same files on these CDN providers, albeit with different URLs. With cdnjs, you can use this direct Bootstrap package link to copy and paste ready-to-use HTML snippets for each dist file from any version of Bootstrap.

If the SRI hashes differ for a given file, you shouldn’t use the files from that CDN, because it means that the file was modified by someone else.

请注意,你应该比较相同长度的哈希值,例如 sha384sha384,否则预计它们会有所不同。因此,你可以使用 SRI 哈希生成器 这样的在线工具来确保给定文件的哈希值相同。或者,假设你安装了 OpenSSL,你可以通过 CLI 实现相同的目的,例如:

¥Note that you should compare same length hashes, e.g. sha384 with sha384, otherwise it’s expected for them to be different. As such, you can use an online tool like SRI Hash Generator to make sure that the hashes are the same for a given file. Alternatively, assuming you have OpenSSL installed, you can achieve the same from the CLI, for example:

openssl dgst -sha384 -binary bootstrap.min.js | openssl base64 -A

包管理器

¥Package managers

使用一些最流行的包管理器将 Bootstrap 的源文件拉入几乎任何项目。无论使用什么包管理器,Bootstrap 都需要 Sass 编译器自动前缀器 来进行与我们的官方编译版本匹配的设置。

¥Pull in Bootstrap’s source files into nearly any project with some of the most popular package managers. No matter the package manager, Bootstrap will require a Sass compiler and Autoprefixer for a setup that matches our official compiled versions.

npm

使用 npm 包 在 Node.js 支持的应用中安装 Bootstrap:

¥Install Bootstrap in your Node.js powered apps with the npm package:

npm install bootstrap@5.3.3

const bootstrap = require('bootstrap')import bootstrap from 'bootstrap' 会将所有 Bootstrap 插件加载到 bootstrap 对象上。bootstrap 模块本身导出我们所有的插件。你可以通过加载包顶层目录下的 /js/dist/*.js 文件来手动单独加载 Bootstrap 的插件。

¥const bootstrap = require('bootstrap') or import bootstrap from 'bootstrap' will load all of Bootstrap’s plugins onto a bootstrap object. The bootstrap module itself exports all of our plugins. You can manually load Bootstrap’s plugins individually by loading the /js/dist/*.js files under the package’s top-level directory.

Bootstrap 的 package.json 在以下键下包含一些附加元数据:

¥Bootstrap’s package.json contains some additional metadata under the following keys:

  • sass - Bootstrap 的主 Sass 源文件的路径

    ¥sass - path to Bootstrap’s main Sass source file

  • style - 使用默认设置(无自定义)编译的 Bootstrap 的非缩小 CSS 的路径

    ¥style - path to Bootstrap’s non-minified CSS that’s been compiled using the default settings (no customization)

Get started with Bootstrap via npm with our starter project! Head to the Sass & JS example template repository to see how to build and customize Bootstrap in your own npm project. Includes Sass compiler, Autoprefixer, Stylelint, PurgeCSS, and Bootstrap Icons.

yarn

使用 Yarn 包 在 Node.js 支持的应用中安装 Bootstrap:

¥Install Bootstrap in your Node.js powered apps with the yarn package:

yarn add bootstrap@5.3.3

RubyGems

通过将以下行添加到 Gemfile,使用 打包器(推荐)和 RubyGems 在 Ruby 应用中安装 Bootstrap:

¥Install Bootstrap in your Ruby apps using Bundler (recommended) and RubyGems by adding the following line to your Gemfile:

gem 'bootstrap', '~> 5.3.3'

或者,如果你不使用 Bundler,则可以通过运行以下命令来安装 gem:

¥Alternatively, if you’re not using Bundler, you can install the gem by running this command:

gem install bootstrap -v 5.3.3

请参阅 gem 的 README 了解更多详情。

¥See the gem’s README for further details.

Composer

你还可以使用 Composer 安装和管理 Bootstrap 的 Sass 和 JavaScript:

¥You can also install and manage Bootstrap’s Sass and JavaScript using Composer:

composer require twbs/bootstrap:5.3.3

NuGet

如果你使用.NET Framework 进行开发,你还可以安装和管理 Bootstrap 的 CSSSass 以及使用 NuGet 的 JavaScript。较新的项目应使用 libman 或其他方法,因为 NuGet 是为编译代码而不是前端资源而设计的。

¥If you develop in .NET Framework, you can also install and manage Bootstrap’s CSS or Sass and JavaScript using NuGet. Newer projects should use libman or another method as NuGet is designed for compiled code, not frontend assets.

Install-Package bootstrap.sass
