GSAP
GSAP is the acronym for GreenSock Animation Platform.

GreenSock Animation Platform
A powerful JavaScript library used to create high-performance animations for websites and web applications. It provides a flexible, easy-to-use API for animating HTML elements, CSS properties, SVG graphics, JavaScript objects, canvas elements, and more.
GSAP is widely regarded as the industry standard for complex, smooth animations in modern web development because of its speed, precision, and extensive browser compatibility. It can handle simple transitions or sophisticated animation sequences with advanced controls over timing, easing, and performance optimization.
Developers use GSAP to animate elements along paths, create scroll-triggered animations, interactive timelines, or complex sequences that would be difficult or impossible with CSS animations alone.
Key Features of GSAP:
- Tweening Engine: Animate any property of any object with robust control over duration, delay, easing, and callbacks.
- Timelines: Chain multiple animations together into a controlled sequence.
- Plugins: Extend functionality with plugins like ScrollTrigger (scroll-based animations), Draggable (drag & drop), MotionPath (path animations), and more.
- Performance Optimized: Designed for high frame rates and smooth animations across all major browsers.
- SVG & Canvas Support: Animate vector graphics and canvas-based content with precision.
- Cross-Browser Compatibility: Ensures consistent animations across modern and older browsers.
GSAP is used by major brands, creative agencies, and developers who want professional-grade animation tools that are flexible and controllable compared to native CSS animations.
