Tailwind CSS 的工作原理是扫描所有 HTML 文件、JavaScript 组件以及任何模板中的 CSS 类(class)名,然后生成相应的样式代码并写入到一个静态 CSS 文件中。他快速、灵活、可靠,没有运行时负担。再也不用为了取一个 classname 类名而烦恼了。
这里以 React + Vite 为例
postcss.config.js
和 tailwind.config.js
配置文件npm install -D tailwindcss postcss autoprefixer
npx tailwindcss init
postcss.config.js
中引入 tailwindcss
和 autoprefixer
module.exports = {
plugins: {
tailwindcss: {},
autoprefixer: {},
}
}
tailwind.config.js
文件/** @type {import('tailwindcss').Config} */
export default {
content: ['./index.html', './src/**/*.{js,ts,jsx,tsx}'],
theme: {
extend: {},
},
plugins: [],
corePlugins: {
preflight: false,
},
}
tailwind.css
入口文件/* @/assets/css/tailwind.css */
@tailwind base;
@tailwind components;
@tailwind utilities;
main.jsx
中引入 tailwind.css
文件import { ConfigProvider } from 'antd'
import ReactDOM from 'react-dom/client'
import zhCN from 'antd/locale/zh_CN'
import Routers from '@/router'
import '@/assets/css/tailwind.css'
import 'dayjs/locale/zh-cn'
ReactDOM.createRoot(document.getElementById('root')).render(
<ConfigProvider locale={zhCN}>
<Routers />
</ConfigProvider>
)
