Keyframes tokens: standardizing animation across projects as a design system pattern¶
Insight: Animation @keyframes suffer from the same fragmentation that design tokens solve for colors and spacing. In component-based architectures, teams working in parallel independently create duplicate fade, slide, zoom, and spin keyframes — three different fade-ins, multiple slide variations, redundant spin animations. Consolidating and standardizing keyframes into a centralized animation system is a reliable quick win on any codebase.
Detail: The problem: without a centralized animation system, developers write @keyframes from scratch unaware similar ones exist elsewhere. This creates animation chaos — wasted development time, code bloat, and multiple maintenance points. The solution mirrors the design token pattern: create a shared, reusable animation token library. This extends the design token concept beyond colors, spacing, and typography into motion and interaction patterns.
