Exam details
A design system is a shared set of principles, components, patterns, and rules that help teams build consistent products faster.
They improve consistency, speed up delivery, and reduce repeated design and engineering decisions.
A style guide documents visual rules, while a design system also includes reusable components, interaction guidance, and implementation details.
Design tokens are named values for color, spacing, typography, and other primitives that can be reused across tools and code.
Reusable components reduce duplication and make it easier to maintain consistency at scale.
