UI Motion Expert

Create "Premium" user experiences through fluid, physical, and meaningful motion.

When to Use This Skill

• Adding "Wow" factor to landing pages.
• Implementing complex page transitions.
• Creating micro-interactions (Hover, Click, Toggle).
• Orchestrating staggered entrance animations.
• Improving perceived performance.

Core Principles

1. Informative: Motion should guide the user's eye and explain relationships (Spatial continuity).
2. Physical: Use spring physics over linear easing for natural feel.
3. Performant: Animate only transform and opacity to stay on the compositor thread.

Micro-Interactions Library

• Buttons: Scale up 1.02 on hover, 95% on click. Lift (translateY(-2px)).
• Inputs: Glow ring (2-4px) with brand color, animated label float.
• Cards: "Premium Lift" - translateY(-4px) + Shadow Increase + Subtle Tilt.
• Lists: Staggered entrance (100ms delay between items).

Tool 1: Framer Motion (React Standard)

Declarative Animations

<motion.div
  initial={{ opacity: 0, y: 20 }}
  animate={{ opacity: 1, y: 0 }}
  transition={{ type: "spring", stiffness: 300, damping: 30 }}
>
  Content
</motion.div>

Layout Animations (Magic Move) Automatically animate layout changes when DOM order changes.

<motion.div layout>
  {/* Content that resizes */}
</motion.div>

Tool 2: CSS Transitions & Keyframes

For simple micro-interactions involving state changes (:hover, :focus).

.card {
  transition: transform 0.2s cubic-bezier(0.2, 0, 0, 1), 
              box-shadow 0.2s ease;
}
.card:hover {
  transform: translateY(-4px);
  box-shadow: var(--shadow-elevation-high);
}

Tool 3: View Transitions API (Modern Web)

Seamless page navigations without framework overhead.

/* Enable view transitions */
@view-transition {
  navigation: auto;
}

"The Premium Feel" Checklist

• Staggered Lists: Don't load everything at once. Stagger items by 50-100ms.
• Feedback: Every interaction (click, tap) has immediate visual feedback.
• Exits: Animate elements out (AnimatePresence in Framer) before removing them.
• Skeleton Loading: Use shimmering skeletons instead of spinners for layout stability.
