Learn GSAP with Real Code Examples
Updated Nov 26, 2025
Explain
GSAP abstracts complex animation logic into simple, chainable commands.
Supports tweening of numeric properties for DOM, SVG, canvas, and JavaScript objects.
Provides timelines for synchronized and sequenced animations.
Includes plugins for scroll-triggered animations, morphing, text effects, and more.
Runs smoothly across browsers with minimal performance overhead.
Core Features
Tween - animates object properties over time
Timeline - sequences multiple tweens
Easing functions - control motion dynamics
Plugins - extend functionality (ScrollTrigger, MorphSVG, etc.)
GSDevTools - debugging and performance tools
Basic Concepts Overview
Tween - animates one or more properties over time
Timeline - sequences and synchronizes multiple tweens
Easing - controls animation acceleration and deceleration
Callback functions - run code at specific animation points
Plugins - enhance GSAP functionality with extra effects
Project Structure
index.html - main HTML content
main.js - GSAP animation scripts
assets/ - images, SVGs, or media files
modules/ - reusable animation functions
styles/ - CSS for initial layout and styling
Building Workflow
Identify the elements or objects to animate
Create tweens or timelines with desired properties
Apply easing and duration settings
Chain animations and callbacks for sequencing
Play, pause, or reverse animations as needed
Difficulty Use Cases
Beginner: fade, move, or scale DOM elements
Intermediate: animate SVG paths and morph shapes
Advanced: scroll-triggered timelines with multiple layers
Expert: integrate GSAP with Three.js or canvas
Architect: build complex interactive web apps with synchronized animations
Comparisons
GSAP vs CSS transitions: more precise and powerful
GSAP vs Anime.js: GSAP more feature-rich and performant
GSAP vs Lottie: GSAP better for custom JS animations, Lottie for JSON vector animations
GSAP vs Velocity.js: GSAP more modern and maintained
GSAP vs ScrollMagic: ScrollTrigger is GSAP’s integrated scroll plugin
