Install Tailwind CSS with Gatsby - Tailwind CSS 中文网

Create your project
Start by creating a new Gatsby project if you don’t have one set up already. The most common approach is to use Gatsby CLI.
Terminal
```
gatsby new my-projectcd my-project
```
Install Tailwind CSS
Using npm, install tailwindcss and its peer dependencies, as well as gatsby-plugin-postcss, and then run the init command to generate both tailwind.config.js and postcss.config.js.
Terminal
```
npm install -D tailwindcss postcss autoprefixer gatsby-plugin-postcssnpx tailwindcss init -p
```
Enable the Gatsby PostCSS plugin
In your gatsby-config.js file, enable the gatsby-plugin-postcss. See the plugin's documentation for more information.
gatsby-config.js
```
module.exports = {
  plugins: [
    'gatsby-plugin-postcss',
    // ...
  ],
}
```

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/pages/**/*.{js,jsx,ts,tsx}",
    "./src/components/**/*.{js,jsx,ts,tsx}",
  ],
  theme: {
    extend: {},
  },
  plugins: [],
}

Add the Tailwind directives to your CSS
Create a ./src/styles/global.css file and add the @tailwind directives for each of Tailwind’s layers.
global.css
```
@tailwind base;
@tailwind components;
@tailwind utilities;
```
Import the CSS file
Create a gatsby-browser.js file at the root of your project if it doesn’t already exist, and import your newly-created ./src/styles/global.css file.
gatsby-browser.js
```
import './src/styles/global.css'
```
Start your build process
Run your build process with gatsby develop.
Terminal
```
gatsby develop
```
