How to Use Tailwind CSS in a React App

Tailwind CSS is a utility-first CSS framework that makes styling React applications efficient and scalable. Whether you are building a simple portfolio or a complex web app, Tailwind CSS offers a powerful set of utilities to help you build modern UIs quickly.

In this guide, you’ll learn everything you need to get started with Tailwind CSS in a React app. From setting up your environment to building a beautiful e-commerce product card, customizing the Tailwind configuration, and exploring component libraries, this tutorial covers it all.

Prerequisites

Before getting started, make sure you have the following tools installed on your system:

• Node.js and npm: Required to manage packages and run your development server.
• Basic knowledge of React: Understanding components, JSX, and state management is essential.
• Code Editor: Preferably VS Code for better developer experience and Tailwind extensions.

To check if you have Node and npm installed, run:

node -v
npm -v

If not installed, download from the official Node.js website: https://nodejs.org

How to Create a React App

To get started with React App and Tailwind CSS, you first need to create a React application using create-react-app.

Step 1: Create the React App

npx create-react-app tailwind-react-app
cd tailwind-react-app

This sets up a boilerplate React app with all the dependencies configured.

Step 2: Start the Development Server

npm start

Your React app will be available at http://localhost:3000.

How to Install Tailwind CSS

Tailwind CSS can be integrated into a React project using PostCSS. Here’s how to install and configure it.

Step 1: Install Tailwind and Dependencies

npm install -D tailwindcss postcss autoprefixer
npx tailwindcss init -p

This creates two files:

• tailwind.config.js
• postcss.config.js

Step 2: Configure Tailwind to Remove Unused Styles

Open tailwind.config.js and update the content array:

module.exports = {
  content: [
    "./src/**/*.{js,jsx,ts,tsx}"
  ],
  theme: {
    extend: {},
  },
  plugins: [],
};

Step 3: Add Tailwind Directives to CSS

Replace the content of src/index.css with the following:

@tailwind base;
@tailwind components;
@tailwind utilities;

Make sure index.css is imported in src/index.js:

You can now use Tailwind utility classes in your React components.

Build an E-commerce Product Card

Let’s create a simple and responsive product card using Tailwind CSS in a React component.

ProductCard.js

import React from 'react';

const ProductCard = () => {
  return (
    <div className="max-w-sm bg-white rounded-lg shadow-md overflow-hidden hover:shadow-xl transition-shadow duration-300">
      <img className="w-full h-48 object-cover" src="https://via.placeholder.com/300" alt="Product" />
      <div className="p-4">
        <h2 className="text-xl font-semibold text-gray-800">Stylish Sneakers</h2>
        <p className="text-gray-600 mt-2">Comfortable and stylish sneakers perfect for everyday wear.</p>
        <div className="flex justify-between items-center mt-4">
          <span className="text-gray-800 font-bold">$89.99</span>
          <button className="bg-blue-500 text-white px-4 py-2 rounded hover:bg-blue-600">Add to Cart</button>
        </div>
      </div>
    </div>
  );
};

export default ProductCard;

You can include this component in App.js like so:

import ProductCard from './ProductCard';

function App() {
  return (
    <div className="flex justify-center items-center h-screen bg-gray-100">
      <ProductCard />
    </div>
  );
}

export default App;

Customize the Tailwind Theme

Tailwind’s configuration can be extended to include custom colors, fonts, and breakpoints.

Example: Add a Custom Color

In tailwind.config.js:

module.exports = {
  theme: {
    extend: {
      colors: {
        brandBlue: '#1e40af',
      },
    },
  },
};

Now you can use bg-brandBlue or text-brandBlue in your components.

Example: Add a Custom Font

extend: {
  fontFamily: {
    custom: ['Poppins', 'sans-serif'],
  },
}

Then use font-custom in your HTML or JSX.

Add Tailwind CSS to React Frameworks

Tailwind CSS can be added to other popular React frameworks as well:

Next.js

1. Create a Next.js app: npx create-next-app my-next-app
2. Install Tailwind: npm install -D tailwindcss postcss autoprefixer
3. Initialize config: npx tailwindcss init -p
4. Update tailwind.config.js and globals.css similarly.

Gatsby

1. Install Tailwind and dependencies: npm install tailwindcss gatsby-plugin-postcss
2. Configure gatsby-config.js to include PostCSS.
3. Import Tailwind in your CSS files.
