Install Tailwind CSS with Create React App - TailwindCSS中文文档

Create React App does not support custom PostCSS configurations and is incompatible with many important tools in the PostCSS ecosystem, like `postcss-import`.

We highly recommend using Vite, Parcel, Next.js, or Remix instead of Create React App. They provide an equivalent or better developer experience but with more flexibility, giving you more control over how Tailwind and PostCSS are configured.

Create your project
Start by creating a new React project with Create React App v5.0+ if you don't have one already set up.
Terminal
```
npx create-react-app my-projectcd my-project
```
Install Tailwind CSS
Install tailwindcss via npm, and then run the init command to generate your tailwind.config.js file.
Terminal
```
npm install -D tailwindcssnpx tailwindcss init
```

Configure your template paths

Add the paths to all of your template files in your tailwind.config.js file.

tailwind.config.js

/** @type {import('tailwindcss').Config} */
module.exports = {
  content: [
    "./src/**/*.{js,jsx,ts,tsx}",
  ],
  theme: {
    extend: {},
  },
  plugins: [],
}

Add the Tailwind directives to your CSS
Add the @tailwind directives for each of Tailwind’s layers to your ./src/index.css file.
index.css
```
@tailwind base;
@tailwind components;
@tailwind utilities;
```
Start your build process
Run your build process with npm run start.
Terminal
```
npm run start
```

Start using Tailwind in your project

Start using Tailwind’s utility classes to style your content.

App.js

export default function App() {
  return (
    <h1 className="text-3xl font-bold underline">
      Hello world!
    </h1>
  )
}
