What is GSAP and Why Use It? {#what-is-gsap}

GreenSock Animation Platform (GSAP) is the industry-standard JavaScript animation library trusted by over 11 million websites worldwide. Unlike CSS animations or other JavaScript libraries, GSAP offers unparalleled performance, cross-browser compatibility, and granular control over every aspect of your animations.

Essential GSAP Animation Techniques {#essential-techniques}

1. Basic Tweening Methods

GSAP provides four core tweening methods:

gsap.to() - Animate TO specified values:

gsap.to(".element", {x: 100, rotation: 360, duration: 2});

gsap.from() - Animate FROM specified values:

gsap.from(".element", {opacity: 0, y: -50, duration: 1});

gsap.fromTo() - Define both starting and ending values:

gsap.fromTo(".element", 
    {scale: 0, rotation: -180}, 
    {scale: 1, rotation: 0, duration: 1.5}
);

2. Transform Properties

GSAP makes CSS transforms simple and powerful:// Smooth, hardware-accelerated transforms

gsap.to(".card", {
    x: 200,           // translateX
    y: 100,           // translateY
    rotation: 45,     // rotate
    scale: 1.5,       // scale
    skewX: 15,        // skewX
    transformOrigin: "center center",
    duration: 2
});

3. Easing Functions

Easing brings life to animations. GSAP offers dozens of built-in easing functions:

// Smooth, natural easing
gsap.to(".element", {x: 300, duration: 2, ease: "power2.out"});

// Bouncy effect
gsap.to(".element", {y: 200, duration: 1.5, ease: "bounce.out"});

// Elastic animation
gsap.to(".element", {scale: 1.2, duration: 1, ease: "elastic.out(1, 0.5)"});

Advanced GSAP Features {#advanced-features}

Timeline Animations

Timelines are GSAP's secret weapon for creating complex, sequenced animations:

- https://gsap.com/docs/v3/GSAP/

const tl = gsap.timeline();

tl.from(".header", {y: -100, opacity: 0, duration: 1})
  .from(".content", {x: -200, opacity: 0, duration: 0.8}, "-=0.3")
  .from(".button", {scale: 0, duration: 0.5, ease: "back.out(1.7)"}, "-=0.2");

ScrollTrigger Plugin

Create scroll-based animations that respond to user interaction:

gsap.registerPlugin(ScrollTrigger);

gsap.to(".parallax-element", {
    y: -200,
    ease: "none",
    scrollTrigger: {
        trigger: ".parallax-element",
        start: "top bottom",
        end: "bottom top",
        scrub: true
    }
});

Morphing SVG Animations

Transform SVG shapes seamlessly:

gsap.to("#morphShape", {
    duration: 2,
    attr: { d: "M0,0 L100,50 L50,100 Z" },
    ease: "power2.inOut"
});
