The design community has started to apply rigor toward documenting and systematizing components in both design and code, but motion is often left out of the discussion. However, motion design falls perfectly in line with the guidelines of a design system: repeatability, time savings, and UX consistencies.
By excluding motion from your design system, you potentially weaken its purpose. Motion in design doesn’t just look cool; it directly contributes to the user experience by delighting, educating, and focusing users.
