拥抱变化，走向未来

Tailwind CSS 是一个功能类优先的 CSS 框架，它集成了诸如 flex, pt-4, text-center 和 rotate-90 这样的的类，它们能直接在脚本标记语言中组合起来，构建出任何设计。

两种方式安装 Tailwind CSS，一种是 CDN 方式，另一种是 npm 方式。CDN 方式不推荐。

使用 CDN 快速体验 Tailwind CSS

使用 npm 安装 Tailwind CSS

第一步：安装 Tailwind CSS

安装 Tailwind CSS 并创建 tailwind.config.js 配置文件

<span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(232, 191, 106) !important">mkdir</span> demo</span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(232, 191, 106) !important">cd</span> demo</span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"><span style="box-sizing: border-box"></span></span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(98, 151, 85) !important"># 安装 tailwindcss</span></span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(232, 191, 106) !important">npm</span> install <span style="box-sizing: border-box;color: rgb(209, 154, 102) !important">-D</span> tailwindcss</span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(98, 151, 85) !important"># 初始化会生成 tailwind.config.js 配置文件</span></span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px">npx tailwindcss init</span>

1）npm install -D tailwindcss 会生成文件及目录

node_modules package-lock.json package.json

2）npx tailwindcss init 生成如下配置文件

tailwind.config.js

第二步：编辑 tailwind.config.js 配置文件

添加文件到配置文件中

<span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(209, 154, 102) !important">module</span>.<span style="box-sizing: border-box;color: rgb(209, 154, 102) !important">exports</span> <span style="box-sizing: border-box;color: rgb(86, 182, 194) !important">=</span> {</span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px">  <span style="box-sizing: border-box;color: rgb(209, 154, 102) !important">content</span>: [<span style="box-sizing: border-box;color: rgb(152, 195, 121) !important">"./src/**/*.{html,js}"</span>],</span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px">  <span style="box-sizing: border-box;color: rgb(209, 154, 102) !important">theme</span>: {</span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px">    <span style="box-sizing: border-box;color: rgb(209, 154, 102) !important">extend</span>: {},</span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px">  },</span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px">  <span style="box-sizing: border-box;color: rgb(209, 154, 102) !important">plugins</span>: [],</span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px">}</span>

第三步：添加 Tailwind 样式指令到 CSS文件中

<span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(98, 151, 85) !important"># demo/src/style.css</span></span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"><span style="box-sizing: border-box"></span></span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px">@tailwind base;</span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px">@tailwind components;</span><br></br><span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px">@tailwind utilities;</span>

第四步：使用 Tailwind Cli 构建 CSS样式

<span style="color: rgb(255, 192, 0);">npx tailwindcss -i ./src/style.css -o ./dist/mystyle.css --watch</span><br></br>

该命令会将 src/style.css 中 Tailwind CSS 编译到 demo/dist/mystyle.css 文件中，mystyle.css 就是编译后样式，项目中引入的就是它。

第五步：小试牛刀

经过上面 4 个小步骤，Tailwind CSS 就已经安装好，下面就来瞅瞅。

<span style="box-sizing: border-box;color: rgb(171, 178, 191);padding-right: 0.1px"><span style="box-sizing: border-box;color: rgb(224, 108, 117) !important"><!doctype
