How To Use Tailwind CSS With Gatsby

1 min read

I'm in the process of updating the design of this blog. I decided to use Tailwind, A utility-first CSS framework. It's an awesome framework, I encourage you to check it out. In this post, we are going to cover how to use Tailwind with Gatsby.

Install Required NPM Packages

Let's first install the following NPM packages:

yarn add -D tailwindcss postcss-preset-env gatsby-plugin-postcss

Configure Tailwind

Let's generate a Tailwind config file by running the following command:

yarn tailwind init

This should generate a tailwind.js file at the root of your project. This is where you can customize Tailwind specifically for your project.

Configure PostCSS

Let's now create the PostCSS config file. Create a postcss.config.js with the following config:

const postcssPresetEnv = require(`postcss-preset-env`)
const tailwindcss = require('tailwindcss')
module.exports = () => ({
plugins: [
stage: 0,

This is the file is automatically read by the Gatsby PostCSS plugin(gatsby-plugin-postcss) we installed earlier.

Update Your Main CSS File

Require the Tailwind CSS in your main CSS file. In my case, I added the following code to my src/styles/main.css file:

@tailwind preflight;
@tailwind utilities;

This is the file I have required in the gatsby-browser.js file.

Note: It might be in a different path for you.

That's it

You should have Tailwind CSS working properly on your Gatsby site. Feel free to check out the source code of this site for reference.
