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
