A design system is not just a Figma UI kit — it is a living contract between product design and engineering. Aligning design tokens for colors, spacing, and typography ensures consistent user experiences across web and mobile surfaces.
Essential Rules for Design Systems
- Tokenize Everything: Define semantic color scales (
bg-card,text-muted,border-border) rather than hardcoding hex values. - Component Isolation: Build components with single responsibilities and standard prop interfaces.
- Accessibility First: Test contrast ratios, focus states, and keyboard navigation upfront.
