DodaTech Updated 2026-06-28 1 min read

In this tutorial, you will learn about Next.js Tailwind CSS Explained. We cover key concepts, practical examples, and best practices to help you master this topic.

Tailwind CSS is a utility-first CSS framework that integrates seamlessly with Next.js, providing rapid styling through composable utility classes without leaving your JSX.

What You'll Learn

  • Tailwind setup in Next.js
  • Utility class patterns
  • Responsive Design with breakpoints
  • Dark mode support
  • Custom theme configuration

Why It Matters

Tailwind's utility classes speed up development by eliminating context switching between JSX and CSS files, while its JIT compiler produces minimal CSS in production.

npx create-next-app@latest my-app --typescript --tailwind

// tailwind.config.js
/** @type {import("tailwindcss").Config} */
module.exports = {
  content: ["./app/**/*.{js,ts,jsx,tsx}", "./components/**/*.{js,ts,jsx,tsx}"],
  darkMode: "class",
  theme: {
    extend: {
      colors: { brand: { 500: "#0070f3", 600: "#0051a2" } },
      fontFamily: { sans: ["Inter", "sans-serif"] },
    },
  },
  plugins: [],
};

// components/Card.jsx
export default function Card({ title, children, variant = "default" }) {
  return (
    <div className="rounded-lg border border-gray-200 bg-white p-6 shadow-sm
      dark:border-gray-700 dark:bg-gray-800 dark:text-white
      hover:shadow-md transition-shadow">
      <h3 className="text-lg font-semibold text-gray-900 dark:text-gray-100
        mb-2">{title}</h3>
      <div className="text-gray-600 dark:text-gray-400">{children}</div>
    </div>
  );
}

Expected output: A responsive card with dark mode support, consistent spacing, and hover effects using Tailwind utility classes.
