Installing with PostCSS - Installation
Tailwind CSS works by scanning all of your HTML files, JavaScript components, and any other templates for class names, generating the corresponding styles and then writing them to a static CSS file.
It's fast, flexible, and reliable — with zero-runtime.
Installing Tailwind CSS as a PostCSS plugin
Installing Tailwind CSS as a PostCSS plugin is the most seamless way to integrate it with frameworks like Next.js and Angular.
Install Tailwind CSS
Install tailwindcss, @tailwindcss/postcss, and postcss via npm.
npm install tailwindcss @tailwindcss/postcss postcssAdd Tailwind to your PostCSS configuration
Add @tailwindcss/postcss to your postcss.config.mjs file, or wherever PostCSS is configured in your project.
export default { plugins: { "@tailwindcss/postcss": {}, }}Import Tailwind CSS
Add an @import to your CSS file that imports Tailwind CSS.
Start your build process
Run your build process with npm run dev or whatever command is configured in your package.json file.
Start using Tailwind in your HTML
Make sure your compiled CSS is included in the <head> (your framework might handle this for you), then start using Tailwind’s utility classes to style your content.
<!doctype html><html><head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <link href="/dist/styles.css" rel="stylesheet"></head><body> <h1 class="text-3xl font-bold underline"> Hello world! </h1></body></html>Are you stuck? Setting up Tailwind with PostCSS can be a bit different across different build tools. Check our framework guides to see if we have more specific instructions for your particular setup.
