Animation Principles for Web Interfaces

The 12 principles of animation from Disney apply directly to web interface design, creating more engaging and intuitive user experiences. Squash and stretch adds life to button interactions, while anticipation prepares users for state changes. Staging focuses attention on important elements, and straight-ahead versus pose-to-pose determines animation workflow. Follow-through creates natural motion ending, while slow-in and slow-out replicate real-world physics through easing functions. Arcs create more natural movement paths than linear animations. Secondary action adds richness without distracting from primary actions. Timing controls animation rhythm and user perception of responsiveness. Exaggeration emphasizes important interactions, solid drawing ensures consistent visual quality, and appeal makes animations enjoyable. CSS transforms and transitions enable performant animations, while JavaScript libraries like GSAP provide advanced control. Performance considerations include using transform and opacity properties, avoiding layout-triggering animations, and respecting reduced motion preferences.
