4.2A pragmatic guide to building the foundations of a design system without boiling the ocean. Written for product designers and front-end developers at small and mid-size teams who keep re-inventing buttons and spacing on every screen. The guide covers the layered architecture real design systems use: design tokens (the smallest decisions — color, spacing, type, radius), then primitives and components built from those tokens, then patterns and documentation. It shows how to define a spacing scale, a sizing system, elevation, and motion as tokens; how to decide what becomes a component versus a one-off; and how to document a component so others actually reuse it (anatomy, states, props, do/don't). It is opinionated about scope: start with tokens and five core components, document as you go, and grow only when there is real reuse. The guide explicitly warns against the common failure modes — building a system no one adopts, over-abstracting too early, and letting design and code drift apart. You will finish with a token sheet, a prioritized component list, a component documentation template, and a contribution/governance lite process. Examples use plain CSS custom properties so they apply to any framework. Best for: teams that have outgrown ad-hoc UI and need a maintainable foundation, and individual designers who want to think in systems.
Both. The token and component model is shared language. Examples are in CSS so developers can implement directly and designers can read along.
No. The architecture is tool-agnostic. It pairs well with Figma variables, but the concepts and CSS work anywhere.
Aimed at small-to-mid teams (roughly 2–30 people) or a solo designer building for a growing product. The guide stresses starting small.
A token is the named design decision; a CSS variable is one way to implement it. The guide explains the layering (raw → semantic) that keeps tokens maintainable.
