Nullstack has built-in support for CSS Modules allowing you to write scoped CSS by automatically creating a unique class name. CSS Module files can be imported anywhere in your application and you don't have to worry about collisions.

Deploy it now with Vercel or preview on StackBlitz:

Execute nulla create with npm:

npx nulla create --example basic-css basic-css-app

Then deploy it with Vercel, Heroku or Netlify.
