Material Design 3
Google Free Intermediate
Google's open design system with detailed guidance on layout, color, type, and components, plus ready implementations. Following an established system gives your product consistency and accessibility for free, which is most of what an early designer would enforce anyway. Useful as a default rulebook when you have no one to make these calls.
- A complete, opinionated system removes hundreds of small decisions.
- Accessibility and consistency come built in.
- Great default rules for when you have no designer to set them.
