Form & Input Animation Principles
Apply Disney's 12 principles to forms for clear feedback and delightful interactions.
Principles Applied to Form Elements
1. Squash & Stretch
Input fields can subtly expand on focus (1-2px height). Submit button compresses on click. Checkboxes bounce on toggle.
2. Anticipation
Label floats up before user types. Focus ring appears before content entry. Prepares user for input action.
3. Staging
Focused input should be visually prominent: border color, shadow, label position. Other fields can slightly dim. Guide attention.
4. Straight Ahead & Pose to Pose
Define input states: default, focus, filled, valid, invalid, disabled. Clear poses for each state with smooth transitions.
5. Follow Through & Overlapping Action
Floating label settles after reaching final position. Validation icon can bounce slightly. Character counter updates with subtle motion.
6. Ease In & Ease Out
Focus transitions: ease-out. Validation feedback: ease-in-out. Label float: cubic-bezier(0.4, 0, 0.2, 1).
7. Arcs
Floating labels should arc slightly during upward movement, not straight line. Adds organic feel to mechanical action.
8. Secondary Action
While border highlights (primary), label floats (secondary), helper text appears (tertiary). Coordinate without overwhelming.
9. Timing
- Focus border: 100-150ms
- Label float: 150-200ms
- Validation feedback: 200ms
- Error shake: 300ms (3-4 cycles)
- Success check: 250ms
- Checkbox toggle: 150ms
10. Exaggeration
Error states can shake (4-6px, 2-3 times). Success states can pulse green briefly. Invalid inputs deserve clear, noticeable feedback.
11. Solid Drawing
Maintain border-radius consistency. Label typography should stay crisp during transform. Icons should scale proportionally.
12. Appeal
Responsive forms feel modern. Micro-animations guide users. Satisfying feedback reduces form abandonment. Worth the investment.
