Set up Master CSS in Next.js

Guide to setting up Master CSS in your Next.js project.

Create a Next.js project

If you don't have a Next.js project, create one first.

npx create-next-app@latest my-app --ts --app --no-tailwindcd my-app

Add Master CSS

Run the installer in runtime mode from the Next.js project root. This injects the Master CSS runtime through Next.js client instrumentation without using the build adapter to pre-render page CSS.

npm create @master/css@rc -- --framework nextjs --mode runtime --yes

Launch server

Run the development server.

npm run dev

Start using Master CSS

Now style your first page using Master CSS syntax.

localhost:3000

Hello World

export default function Home() {    return (        <h1 className="m:2xl italic font:5xl font:heavy text:neutral">            Hello World        </h1>    )}
