Micro-Interactions

Implement subtle, purposeful animations that provide feedback, guide attention, and create delightful user experiences without overwhelming the interface.

Overview

Micro-interactions are small, focused animations that:

• Provide feedback on user actions
• Guide attention to important elements
• Create delight through polish
• Communicate state changes

Hover State Patterns

<div class="rounded-2xl bg-white shadow-md
            hover:-translate-y-1 hover:shadow-lg
            transition-all duration-300">
  <!-- Card content -->
</div>

Image Scale

<div class="group overflow-hidden rounded-xl">
  <img src="image.jpg" 
       class="w-full transition-transform duration-500 
              group-hover:scale-105" 
       alt="Zoomable image">
</div>

Border Glow

<div class="rounded-2xl border border-white/10 bg-neutral-900
            hover:border-white/20 hover:shadow-2xl hover:shadow-brand-500/10
            transition-all duration-500">
  <!-- Content -->
</div>

Text Color Change

<h3 class="text-zinc-900 group-hover:text-brand-600

  Hover to change color
</h3>

Background Shift

<div class="bg-white hover:bg-zinc-50 
            transition-colors duration-500">

Group Hover Patterns

Use group class on parent to trigger child animations:

<div class="group rounded-2xl p-6">
  <!-- Icon scales on card hover -->
  <div class="w-10 h-10 rounded-xl bg-brand-50
              group-hover:scale-110 
              transition-transform duration-300">
    <!-- Icon -->
  </div>
  
  <!-- Title changes color -->
  <h3 class="text-zinc-900 group-hover:text-brand-600 
             transition-colors duration-300">
    Feature Title
  </h3>
  
  <!-- Element slides -->
  <div class="group-hover:translate-x-1 
              transition-transform duration-300">

  </div>
</div>

Staggered Animations

Use delay utilities for sequential reveals:

<div class="grid grid-cols-4 gap-4">
  <div class="group-hover:translate-y-[-4px] transition-transform duration-300">
    Step 1
  </div>
  <div class="group-hover:translate-y-[-4px] transition-transform duration-300 delay-100">
    Step 2
  </div>
  <div class="group-hover:translate-y-[-4px] transition-transform duration-300 delay-200">
    Step 3
  </div>
  <div class="group-hover:translate-y-[-4px] transition-transform duration-300 delay-300">
    Step 4
  </div>
</div>

Timing Guidelines

| Interaction Type | Duration | Use Case | |------------------|----------|----------| | Instant | 100-150ms | Button press, toggle | | Quick | 200-300ms | Hover states, small reveals | | Standard | 300-500ms | Card animations, transitions | | Dramatic | 500-700ms | Hero reveals, page transitions | | Slow | 700-1000ms | Background effects, ambient |

Performance Best Practices

/* Only animate transform and opacity for best performance */
.optimized-animation {
  will-change: transform, opacity;
  transform: translateZ(0); /* GPU acceleration */
}

/* Avoid animating */
.avoid {
  /* ❌ Don't animate: width, height, top, left, margin, padding, box-shadow */
}

Accessibility

<!-- Respect reduced motion preferences -->
<div class="motion-safe:hover:-translate-y-1 
            motion-safe:transition-transform 
            motion-safe:duration-300">
  Respects user preferences
</div>

@media (prefers-reduced-motion: reduce) {
  * {
    animation-duration: 0.01ms !important;
    transition-duration: 0.01ms !important;
  }
}
