3D Animations Skill

3D Animations Skill

Expert knowledge for CSS/JS-based 3D animations - perspective transforms, depth effects, card flips, cube rotations, and parallax depth without WebGL.

When to Use

Activate this skill when:

• User wants 3D flip cards
• Creating perspective-based animations
• Building parallax depth effects
• Need rotating cubes or 3D objects
• Creating tilt-on-hover effects
• Building 3D carousels

File Patterns

• **/*.tsx with 3D transform components
• **/components/*3D*.tsx
• **/components/*Flip*.tsx
• **/components/*Tilt*.tsx

Core Concepts

Perspective

/* Parent container needs perspective */
.perspective-container {
  perspective: 1000px;
  perspective-origin: center;
}

/* Child can now use 3D transforms */
.card-3d {
  transform-style: preserve-3d;
  transform: rotateY(45deg);
}

3D Animation Types

1. 3D Flip Cards

Basic Flip Card

import { motion } from 'framer-motion';
import { useState } from 'react';

interface FlipCardProps {
  front: React.ReactNode;
  back: React.ReactNode;
}

export function FlipCard({ front, back }: FlipCardProps) {
  const [isFlipped, setIsFlipped] = useState(false);

  return (
    <div
      className="relative w-64 h-80 cursor-pointer"
      style={{ perspective: '1000px' }}
      onClick={() => setIsFlipped(!isFlipped)}
    >
      <motion.div
        className="w-full h-full relative"
        style={{ transformStyle: 'preserve-3d' }}
        animate={{ rotateY: isFlipped ? 180 : 0 }}
        transition={{ duration: 0.6, type: 'spring', stiffness: 100 }}
      >
        {/* Front */}
        <div
          className="absolute inset-0 bg-gradient-to-br from-purple-500 to-pink-500 rounded-xl p-6 flex items-center justify-center"
          style={{ backfaceVisibility: 'hidden' }}
        >
          {front}
        </div>

        {/* Back */}
        <div
          className="absolute inset-0 bg-gradient-to-br from-blue-500 to-cyan-500 rounded-xl p-6 flex items-center justify-center"
          style={{ backfaceVisibility: 'hidden', transform: 'rotateY(180deg)' }}
        >
          {back}
        </div>
      </motion.div>
    </div>
  );
}

Flip Card on Hover

export function HoverFlipCard({ front, back }: FlipCardProps) {
  return (
    <motion.div
      className="relative w-64 h-80 cursor-pointer group"
      style={{ perspective: '1000px' }}
      whileHover="flipped"
      initial="initial"
    >
      <motion.div
        className="w-full h-full relative"
        style={{ transformStyle: 'preserve-3d' }}
        variants={{
          initial: { rotateY: 0 },
          flipped: { rotateY: 180 },
        }}
        transition={{ duration: 0.6 }}
      >
        <div
          className="absolute inset-0 bg-white rounded-xl shadow-xl p-6"
          style={{ backfaceVisibility: 'hidden' }}
        >
          {front}
        </div>
        <div
          className="absolute inset-0 bg-slate-900 text-white rounded-xl shadow-xl p-6"
          style={{ backfaceVisibility: 'hidden', transform: 'rotateY(180deg)' }}
        >
          {back}
        </div>
      </motion.div>
    </motion.div>
  );
}

2. Tilt Effects

Tilt on Hover

import { motion, useMotionValue, useSpring, useTransform } from 'framer-motion';

export function TiltCard({ children }: { children: React.ReactNode }) {
  const x = useMotionValue(0);
  const y = useMotionValue(0);

  const rotateX = useSpring(useTransform(y, [-0.5, 0.5], [15, -15]), {
    stiffness: 300,
    damping: 30,
  });
  const rotateY = useSpring(useTransform(x, [-0.5, 0.5], [-15, 15]), {
    stiffness: 300,
    damping: 30,
  });

  const handleMouseMove = (e: React.MouseEvent<HTMLDivElement>) => {
    const rect = e.currentTarget.getBoundingClientRect();
    const centerX = rect.left + rect.width / 2;
    const centerY = rect.top + rect.height / 2;

    x.set((e.clientX - centerX) / rect.width);
    y.set((e.clientY - centerY) / rect.height);
  };

  const handleMouseLeave = () => {
    x.set(0);
    y.set(0);
  };

  return (
    <motion.div
      className="relative bg-white rounded-xl shadow-xl p-6"
      style={{
        perspective: '1000px',
        rotateX,
        rotateY,
        transformStyle: 'preserve-3d',
      }}
      onMouseMove={handleMouseMove}
      onMouseLeave={handleMouseLeave}
    >
      <div style={{ transform: 'translateZ(50px)' }}>{children}</div>
    </motion.div>
  );
}

Tilt with Shine Effect

export function ShinyTiltCard({ children }: { children: React.ReactNode }) {
  const x = useMotionValue(0);
  const y = useMotionValue(0);

  const rotateX = useSpring(useTransform(y, [-0.5, 0.5], [10, -10]));
  const rotateY = useSpring(useTransform(x, [-0.5, 0.5], [-10, 10]));
  const shineX = useTransform(x, [-0.5, 0.5], ['0%', '100%']);
  const shineY = useTransform(y, [-0.5, 0.5], ['0%', '100%']);

  const handleMouseMove = (e: React.MouseEvent<HTMLDivElement>) => {
    const rect = e.currentTarget.getBoundingClientRect();
    x.set((e.clientX - rect.left) / rect.width - 0.5);
    y.set((e.clientY - rect.top) / rect.height - 0.5);
  };

  return (
    <motion.div
      className="relative overflow-hidden rounded-xl bg-gradient-to-br from-purple-500 to-pink-500 p-8"
      style={{ rotateX, rotateY, transformStyle: 'preserve-3d' }}
      onMouseMove={handleMouseMove}
      onMouseLeave={() => { x.set(0); y.set(0); }}
    >
      {/* Shine overlay */}
      <motion.div
        className="absolute inset-0 pointer-events-none"
        style={{
          background: `radial-gradient(circle at ${shineX} ${shineY}, rgba(255,255,255,0.3) 0%, transparent 50%)`,
        }}
      />
      <div style={{ transform: 'translateZ(30px)' }}>{children}</div>
    </motion.div>
  );
}
