Custom Animations

1. Define Keyframes

Define custom animations in tailwind.config.js.

javascript
// tailwind.config.js
module.exports = {
  theme: {
    extend: {
      keyframes: {
        'fade-in': {
          '0%': { opacity: '0' },
          '100%': { opacity: '1' },
        },
        'slide-up': {
          '0%': { transform: 'translateY(100%)' },
          '100%': { transform: 'translateY(0)' },
        },
        'slide-down': {
          '0%': { transform: 'translateY(-100%)' },
          '100%': { transform: 'translateY(0)' },
        },
        'scale-in': {
          '0%': { transform: 'scale(0)' },
          '100%': { transform: 'scale(1)' },
        },
      },
      animation: {
        'fade-in': 'fade-in 0.5s ease-out',
        'slide-up': 'slide-up 0.5s ease-out',
        'slide-down': 'slide-down 0.5s ease-out',
        'scale-in': 'scale-in 0.5s ease-out',
      },
    },
  },
}

2. Use Custom Animations

html
<!-- Fade-in animation -->
<div class="animate-fade-in">
  Fade-in effect
</div>

<!-- Slide-up animation -->
<div class="animate-slide-up">
  Slide-up effect
</div>

<!-- Slide-down animation -->
<div class="animate-slide-down">
  Slide-down effect
</div>

<!-- Scale-in animation -->
<div class="animate-scale-in">
  Scale-in effect
</div>

3. Complex Custom Animations

javascript
// tailwind.config.js
module.exports = {
  theme: {
    extend: {
      keyframes: {
        'wiggle': {
          '0%, 100%': { transform: 'rotate(-3deg)' },
          '50%': { transform: 'rotate(3deg)' },
        },
        'float': {
          '0%, 100%': { transform: 'translateY(0)' },
          '50%': { transform: 'translateY(-20px)' },
        },
        'shake': {
          '0%, 100%': { transform: 'translateX(0)' },
          '10%, 30%, 50%, 70%, 90%': { transform: 'translateX(-10px)' },
          '20%, 40%, 60%, 80%': { transform: 'translateX(10px)' },
        },
      },
      animation: {
        'wiggle': 'wiggle 1s ease-in-out infinite',
        'float': 'float 3s ease-in-out infinite',
        'shake': 'shake 0.5s ease-in-out',
      },
    },
  },
}

  Wiggle effect
</div>

<!-- Float animation -->
<div class="animate-float">
  Float effect
</div>

<!-- Shake animation -->
<div class="animate-shake">
  Shake effect
</div>

Practical Animation Examples

1. Loading Animations

html
<!-- Spinner loader -->
<div class="flex items-center justify-center">
  <div class="animate-spin rounded-full h-12 w-12 border-b-2 border-blue-500"></div>
</div>

<!-- Pulse loader -->
<div class="flex items-center justify-center">
  <div class="animate-pulse rounded-full h-12 w-12 bg-blue-500"></div>
</div>

<!-- Bounce loader -->
<div class="flex space-x-2">
  <div class="animate-bounce rounded-full h-3 w-3 bg-blue-500"></div>
  <div class="animate-bounce rounded-full h-3 w-3 bg-blue-500" style="animation-delay: 0.1s"></div>
  <div class="animate-bounce rounded-full h-3 w-3 bg-blue-500" style="animation-delay: 0.2s"></div>
</div>

2. Hover Effects

html
<!-- Button hover -->
<button class="
  bg-blue-500 hover:bg-blue-600
  hover:scale-105 hover:shadow-lg
  transition-all duration-300 ease-in-out
  text-white font-bold py-2 px-4 rounded
">
  Hover button
</button>

<!-- Card hover -->
<div class="
  bg-white rounded-lg shadow-md
  hover:shadow-xl hover:-translate-y-2
  transition-all duration-300 ease-in-out
  p-6
">
  <h3 class="font-bold mb-2">Card title</h3>
  <p class="text-gray-600">Card content</p>
</div>

<!-- Image hover -->
<div class="overflow-hidden rounded-lg">
  <img 
    src="image.jpg" 
    alt="Hover image"
    class="w-full h-48 object-cover hover:scale-110 transition-transform duration-500"
  >
</div>

3. Page Transitions

html
<!-- Fade-in page -->
<div class="animate-fade-in">
  <h1>Page title</h1>
  <p>Page content</p>
</div>

<!-- Slide-up page -->
<div class="animate-slide-up">
  <h1>Page title</h1>
  <p>Page content</p>
</div>

4. Interactive Feedback

html
<!-- Click feedback -->
<button class="
  bg-blue-500 hover:bg-blue-600
  active:scale-95
  transition-all duration-150
  text-white font-bold py-2 px-4 rounded
">
  Click button
</button>

<!-- Focus feedback -->
<input 
  type="text" 
  placeholder="Input field"
  class="
    border border-gray-300 rounded
    focus:ring-2 focus:ring-blue-500 focus:border-transparent
    transition-all duration-200
    px-4 py-2
  "
>

Animation Performance Optimization

1. Use transform and opacity

html
<!-- ✅ Recommended: Use transform -->
<div class="hover:scale-110 transition-transform duration-300">
  Scale effect
</div>

<!-- ❌ Not recommended: Use width/height -->
<div class="hover:w-[110%] transition-all duration-300">
  Scale effect
</div>

<!-- ✅ Recommended: Use opacity -->
<div class="hover:opacity-75 transition-opacity duration-300">
  Opacity effect
</div>

2. Use will-change

html
<!-- Hint browser optimization -->
<div class="
  hover:scale-110
  will-change-transform
  transition-transform duration-300
">
  Optimized animation
</div>

3. Avoid Layout Thrashing

html
<!-- ✅ Recommended: Use transform -->
<div class="hover:-translate-y-2 transition-transform duration-300">
  Move up
</div>

<!-- ❌ Not recommended: Use margin -->
<div class="hover:-mt-2 transition-all duration-300">
  Move up
</div>

Animation Best Practices

1. Keep It Simple

html
<!-- ✅ Recommended: Simple animation -->
<div class="hover:scale-105 transition-transform duration-200">
  Simple animation
</div>

<!-- ❌ Not recommended: Overly complex animation -->
<div class="
  hover:scale-105 hover:rotate-3 hover:shadow-xl
  transition-all duration-500 ease-in-out
">
  Complex animation
</div>

2. Consider Accessibility

html
<!-- Respect user's animation preferences -->
@media (prefers-reduced-motion: reduce) {
  .animate-fade-in {
    animation: none;
  }
}

3. Use Appropriate Duration

html
<!-- Fast interaction (100-200ms) -->
<button class="hover:bg-blue-500 transition-colors duration-150">
  Fast interaction
</button>

<!-- Standard transition (200-300ms) -->
<div class="hover:scale-105 transition-transform duration-250">
  Standard transition
</div>

<!-- Complex animation (300-500ms) -->
<div class="animate-slide-up">
  Complex animation
</div>

Considerations

1. Performance: Prioritize using transform and opacity, avoid triggering reflow
2. User Experience: Don't overuse animations, keep interface smooth
3. Accessibility: Respect user's animation preference settings
4. Browser Compatibility: Test animations on different browsers
5. Mobile Devices: Consider performance limitations of mobile devices
