State Change Animations

Apply Disney's 12 principles when elements transform without leaving.

Principle Application

Squash & Stretch: Elements compress before expanding. A toggle switch squashes 5% before sliding.

Anticipation: Wind up before the change. Slight reverse movement (2-3px) before expanding.

Staging: Keep transformations centered on user focus. Don't let state changes distract from the interaction point.

Straight Ahead vs Pose-to-Pose: Define exact states. Button has rest, hover, active, disabled - each precisely designed.

Follow Through & Overlapping: Parts transform at different rates. Icon rotates before label fades in.

Slow In/Slow Out: Use ease-in-out for bidirectional changes: cubic-bezier(0.4, 0, 0.2, 1).

Arcs: Rotating elements follow natural arcs. Chevrons rotate on their center point, not linearly.
