Animation Engines & Libraries

CSS Animations & Transitions

Transitions:

/* Performant properties: transform, opacity */
.element {
  transition: transform 0.3s cubic-bezier(0.4, 0, 0.2, 1),
              opacity 0.3s ease-out;
  will-change: transform; /* GPU acceleration hint */
}
.element:hover {
  transform: translateY(-4px) scale(1.02);
  opacity: 0.9;
}

Keyframe Animations:

@keyframes slideInUp {
  from {
    transform: translateY(30px);
    opacity: 0;
  }
  to {
    transform: translateY(0);
    opacity: 1;
  }
}

@keyframes pulse {
  0%, 100% { transform: scale(1); }
  50% { transform: scale(1.05); }
}

@keyframes shimmer {
  0% { background-position: -200% 0; }
  100% { background-position: 200% 0; }
}

Advanced CSS:

• CSS custom properties for dynamic animations
• CSS Houdini (Paint API, Layout API)
• CSS scroll-driven animations (@scroll-timeline)
• View Transitions API
• Container queries with animations
• @starting-style for entry animations
• CSS motion path (offset-path)

Framer Motion (React)

import { motion, AnimatePresence, useScroll, useTransform } from 'framer-motion';

// Layout animations
<motion.div layout layoutId="shared-element" />

// Gesture animations
<motion.div
  whileHover={{ scale: 1.05, rotateZ: 2 }}
  whileTap={{ scale: 0.95 }}
  drag="x"
  dragConstraints={{ left: -100, right: 100 }}
/>

// Scroll-linked animations
const { scrollYProgress } = useScroll();
const opacity = useTransform(scrollYProgress, [0, 0.5], [0, 1]);
const scale = useTransform(scrollYProgress, [0, 1], [0.8, 1]);

// Staggered children
const container = {
  hidden: { opacity: 0 },
  show: {
    opacity: 1,
    transition: { staggerChildren: 0.1, delayChildren: 0.3 }
  }
};

// Exit animations
<AnimatePresence mode="wait">
  {isVisible && (
    <motion.div
      key="modal"
      initial={{ opacity: 0, y: 50 }}
      animate={{ opacity: 1, y: 0 }}
      exit={{ opacity: 0, y: -50 }}
      transition={{ type: "spring", stiffness: 300, damping: 30 }}
    />
  )}
</AnimatePresence>

// Shared layout animations (morphing between components)
<LayoutGroup>
  <motion.div layoutId="underline" />
</LayoutGroup>
