Visual Design Systems, Layout Theory, and Design Tokens
Visual systems as infrastructure
Beyond aesthetics
At scale, visual design becomes a governed system of reusable rules and tokens rather than isolated page decoration. Spacing, color, typography, elevation, motion, and iconography must work together consistently across products and teams.
Design token categories
Color tokens
Named values for semantic and functional colors.
Typography tokens
Font families, sizes, line heights, and weights.
Spacing tokens
A consistent scale for margin, padding, and layout gaps.
Motion tokens
Durations, easing curves, and transition rules.
Principles of layout hierarchy
| Principle | Effect |
|---|---|
| Contrast | Separates primary from secondary elements |
| Alignment | Creates order and visual stability |
| Proximity | Groups related content |
| Repetition | Builds consistency and recognition |
