Motion One Animation Principles

Implement all 12 Disney animation principles using Motion One's performant Web Animations API wrapper.

1. Squash and Stretch

import { animate } from "motion";

animate(".ball", { scaleX: [1, 1.2, 1], scaleY: [1, 0.8, 1] }, { duration: 0.3, easing: "ease-in-out" } );

2. Anticipation

import { timeline } from "motion";

timeline([ [".character", { y: 10, scaleY: 0.9 }, { duration: 0.2 }], [".character", { y: -200 }, { duration: 0.4, easing: "ease-out" }] ]);

3. Staging

animate(".background", { filter: "blur(3px)", opacity: 0.6 }); animate(".hero", { scale: 1.1 });

4. Straight Ahead / Pose to Pose

animate(".element", { x: [0, 100, 200, 300], y: [0, -50, 0, -30] }, { duration: 1 });

5. Follow Through and Overlapping Action

timeline([ [".body", { x: 200 }, { duration: 0.5 }], [".hair", { x: 200 }, { duration: 0.5, at: "-0.45" }], [".cape", { x: 200 }, { duration: 0.6, at: "-0.5" }] ]);

6. Slow In and Slow Out

animate(".element", { x: 300 }, { duration: 0.6, easing: [0.42, 0, 0.58, 1] // cubic-bezier ease-in-out }); // Or: "ease-in", "ease-out", "ease-in-out" // Or spring: { easing: spring({ stiffness: 100, damping: 15 }) }

7. Arc

animate(".ball", { x: [0, 100, 200], y: [0, -100, 0] }, { duration: 1, easing: "ease-in-out" });

// Or with offset path animate(".element", { offsetDistance: ["0%", "100%"] }, { duration: 1 }); // CSS: offset-path: path('M0,100 Q100,0 200,100');

8. Secondary Action

const button = document.querySelector(".button"); button.addEventListener("mouseenter", () => { animate(button, { scale: 1.05 }, { duration: 0.2 }); animate(".icon", { rotate: 15 }, { duration: 0.15 }); });

9. Timing

import { spring } from "motion";

// Fast snap animate(".fast", { x: 100 }, { duration: 0.15 });

// Spring physics animate(".spring", { x: 100 }, { easing: spring({ stiffness: 300, damping: 20 }) });

// Slow dramatic animate(".slow", { x: 100 }, { duration: 0.8, easing: "ease-out" });

10. Exaggeration

import { spring } from "motion";

animate(".element", { scale: 1.5, rotate: 720 }, { easing: spring({ stiffness: 200, damping: 10 }) // overshoot });

11. Solid Drawing

animate(".box", { rotateX: 45, rotateY: 30 }, { duration: 0.5 }); // Set perspective in CSS: perspective: 1000px;

12. Appeal

animate(".card", { scale: 1.02, boxShadow: "0 20px 40px rgba(0,0,0,0.2)" }, { duration: 0.3, easing: "ease-out" });

Stagger Animation

import { stagger } from "motion";

animate(".item", { opacity: [0, 1], y: [20, 0] }, { delay: stagger(0.1) } );

Scroll Animations

import { scroll, animate } from "motion";

scroll( animate(".parallax", { y: [0, 100] }), { target: document.querySelector(".container") } );

In-View Animations

import { inView } from "motion";

inView(".section", ({ target }) => { animate(target, { opacity: 1, y: 0 }, { duration: 0.5 }); });
