⏤ Why this document?
As digital products grow in complexity and expand across platforms, maintaining consistency becomes increasingly challenging.A well-structured design system helps teams scale product development while preserving a coherent user experience.
⏤ Who is this for?
This document brings together lessons learned from implementing design systems at Qwant, Ekwateur, and Anycommerce.It is intended for design teams working on mature digital products, where consistency, collaboration, and efficient feature delivery are essential.
⏤ What ?
Define a clear set of foundational tokens for colors, typography, spacing, shadows, border radii, motion, and opacity.
⏤ But why ?
These foundational tokens provide a consistent reference point and make it easier to evolve the visual language of a product over time.
⏤ What ?
Give each UI role a meaningful name that describes its purpose rather than its visual value.
⏤ But why ?
Semantic tokens connect foundational values to real interface needs, giving designers and developers a shared language and making the system easier to maintain.
⏤ What ?
Create components using semantic tokens, with clearly defined variants, states, and sizing rules.
⏤ But why ?
Reusable components improve consistency, reduce duplication, and help teams build and maintain interfaces more efficiently.
⏤ What ?
Identify recurring page structures and create templates that support common use cases.
⏤ But why ?
Reusable layouts standardize page structures, simplify documentation, and help teams deliver consistent experiences across the product.
I hope this approach helps you structure and evolve your own design system.
