Installation & Quick Start

npm install gsap

import gsap from 'gsap';
import { ScrollTrigger } from 'gsap/ScrollTrigger';

gsap.registerPlugin(ScrollTrigger);

// Create a sequenced timeline linked to scroll
const tl = gsap.timeline({
  scrollTrigger: {
    trigger: '.hero-section',
    start: 'top center',
    end: 'bottom top',
    scrub: 1,
  },
});

tl.from('.title', { y: 60, opacity: 0, duration: 1, ease: 'power3.out' })
  .from('.subtitle', { y: 30, opacity: 0, duration: 0.8 }, '-=0.5')
  .to('.cta-button', { scale: 1.08, repeat: -1, yoyo: true, ease: 'sine.inOut' });

Why Choose GSAP?

• Best Suited For: Production-grade marketing sites, creative portfolio showcases, Awwwards-style scroll storytelling, and complex interactive web applications requiring precise multi-step choreography.
• Trade-offs: Slightly larger bundle footprint than micro-animation utilities, but unmatched in capability, reliability, and cross-browser stability.
