Hover Interaction Animations
Apply Disney's 12 principles to mouse hover states.
Principle Application
Squash & Stretch: Cards can subtly scale (1.02-1.05) on hover, creating "lift" effect.
Anticipation: Hover IS anticipation for click. The hover state previews the interaction.
Staging: Hover effects should highlight the interactive element, not distract from it.
Straight Ahead vs Pose-to-Pose: Define rest and hover poses precisely. Transition smoothly between them.
Follow Through & Overlapping: Child elements animate after parent. Card lifts, then shadow expands.
Slow In/Slow Out: Hover-in: ease-out (fast response). Hover-out: ease-in-out (graceful return).
Arcs: Underlines can draw from center outward. Highlights sweep in curved paths.
Secondary Action: Combine multiple subtle effects. Scale + shadow + color shift together.
Timing:
- Hover response: 150-200ms (must feel responsive)
- Hover exit: 200-300ms (can be slightly slower)
- Never exceed 300ms for hover-in
Exaggeration: Subtle - hover is preview, not performance. Scale max 1.05, shadow max +8px.
Solid Drawing: Hover states must feel like the same element elevated, not a replacement.
Appeal: Hover should invite clicking. Create anticipation without demanding action.
Timing Recommendations
| Hover Effect | Hover-In | Hover-Out | Easing |
|---|---|---|---|
| Color Change | 150ms | 200ms | ease-out / ease-in-out |
| Scale/Lift | 200ms | 250ms | ease-out / ease-in-out |
| Shadow | 200ms | 250ms | ease-out / ease-in-out |
| Underline Draw | 200ms | 200ms | ease-out |
| Image Zoom | 300ms | 400ms | ease-out |
| Icon Shift | 150ms | 200ms | ease-out |
Implementation Patterns
/* Card lift with shadow */
.card {
transition: transform 200ms ease-out, box-shadow 200ms ease-out;
}
.card:hover {
transform: translateY(-4px) scale(1.02);
box-shadow: 0 12px 24px rgba(0,0,0,0.15);
}
/* Slower return */
.card:not(:hover) {
transition: transform 250ms ease-in-out, box-shadow 250ms ease-in-out;
}
/* Underline draw from center */
.link {
position: relative;
}
.link::after {
content: '';
position: absolute;
bottom: 0;
left: 50%;
width: 0;
height: 2px;
background: currentColor;
transition: width 200ms ease-out, left 200ms ease-out;
}
.link:hover::after {
width: 100%;
left: 0;
}
Icon Animation Pattern
.button-icon {
transition: transform 150ms ease-out;
}
.button:hover .button-icon {
transform: translateX(4px);
}
/* Arrow grows */
.arrow-icon {
transition: transform 150ms ease-out;
}
.link:hover .arrow-icon {
transform: translateX(4px) scale(1.1);
}
Key Rules
- Touch devices don't have hover - ensure functionality without it
- Hover-in must be under 200ms to feel responsive
- Don't move elements enough to cause mis-clicks
- Test with
@media (hover: hover)to scope to pointer devices - Combine max 3 properties to avoid overwhelming
@media (hover: hover) {
.card:hover { /* hover effects */ }
}
FAQ
