A design system is a shared collection of reusable UI components, visual styles, and documentation that defines how a product should look and behave.

It includes things like:

• Buttons, icons, and forms

• Color palettes and typography

• Interaction rules and code components

Design systems serve as a single source of truth for designers and developers, ensuring consistency across products, saving time by reusing elements, and making collaboration smoother.

For beginners, a design system offers clear guidance. For teams, it enables faster, more unified product development—boosting both efficiency and brand quality.
