Information

Our templates are configured to use Tailwind V3. This would update them to use Tailwind V4 using the Postcss configuration that better supports Angular components, and styles from libraries.

https://tailwindcss.com/docs/installation/using-postcss

export default {
  plugins: {
    "@tailwindcss/postcss": {},
  }
}

The minimal, latest, and blog templates are here
