Tailwind with Next.js

Definition

The integration and optimization of Tailwind CSS within the Next.js framework.

Explain Like I'm New

Next.js and Tailwind are a match made in heaven. When you run `npx create-next-app`, Tailwind is configured automatically. The most important thing to know is that Tailwind works perfectly with Next.js Server Components, shipping zero CSS-in-JS runtime payload to the client.

Real World Example

Using Tailwind classes directly inside a Next.js App Router layout file (`app/layout.tsx`) to style the global `<body>` tag.

Common Use Cases

•Full-stack React apps

Answer

No. The Next.js CLI asks you 'Would you like to use Tailwind CSS?' and sets up the PostCSS configuration, config file, and global CSS automatically.

Question

Impact JS bundle?

Answer

Zero impact. Tailwind outputs raw, static CSS. Unlike styled-components or Emotion, Tailwind does not require any JavaScript to calculate or inject styles at runtime.
