# GSAP (GreenSock Animation Platform)

[![GSAP - Animate anything](https://gsap.com/GSAP-share-image.png)](https://gsap.com)

GSAP is a **framework-agnostic** JavaScript animation library that turns developers into animation superheroes. Build high-performance animations that work in **every** major browser. Animate CSS, SVG, canvas, React, Vue, WebGL, colors, strings, motion paths, generic objects... anything JavaScript can touch! GSAP's <a href="https://gsap.com/docs/v3/Plugins/ScrollTrigger/">ScrollTrigger</a> plugin delivers jaw-dropping scroll-based animations with minimal code. <a href="https://gsap.com/docs/v3/GSAP/gsap.matchMedia()">gsap.matchMedia()</a> makes building responsive, accessibility-friendly animations a breeze.

No other library delivers such advanced sequencing, reliability, and tight control while solving real-world problems on over 12 million sites. GSAP works around countless browser inconsistencies; your animations ***just work***. At its core, GSAP is a high-speed property manipulator, updating values over time with extreme accuracy. It's up to 20x faster than jQuery!

GSAP is completely flexible; sprinkle it wherever you want. **Zero dependencies.**

There are many optional <a href="https://gsap.com/docs/v3/Plugins">plugins</a> and <a href="https://gsap.com/docs/v3/Eases">easing</a> functions for achieving advanced effects easily like <a href="https://gsap.com/docs/v3/Plugins/ScrollTrigger/">scrolling</a>, <a href="https://gsap.com/docs/v3/Plugins/MorphSVGPlugin">morphing</a>, [text splitting](https://gsap.com/docs/v3/Plugins/SplitText), animating along a <a href="https://gsap.com/docs/v3/Plugins/MotionPathPlugin">motion path</a> or <a href="https://gsap.com/docs/v3/Plugins/Flip/">FLIP</a> animations. There's even a handy <a href="https://gsap.com/docs/v3/Plugins/Observer/">Observer</a> for normalizing event detection across browsers/devices.

### Get Started

[![Get Started with GSAP](https://gsap.com/_img/github/get-started.jpg)](https://gsap.com/get-started)

## Docs &amp; Installation

View the <a href="https://gsap.com/docs">full documentation here</a>, including an <a href="https://gsap.com/install">installation guide</a>.

### CDN

```html
<script src="https://cdn.jsdelivr.net/npm/gsap@3.15/dist/gsap.min.js"></script>
```

See <a href="https://www.jsdelivr.com/gsap">JSDelivr's dedicated GSAP page</a> for quick CDN links to the core files/plugins. There are more <a href="https://gsap.com/install">installation instructions</a> at gsap.com.

**Every major ad network excludes GSAP from file size calculations** and most have it on their own CDNs, so contact them for the appropriate URL(s).

### NPM
See the <a href="https://gsap.com/install">guide to using GSAP via NPM here</a>.

```javascript
npm install gsap
```

GSAP's core can animate almost anything including CSS and attributes, plus it includes all of the <a href="https://gsap.com/docs/v3/GSAP/UtilityMethods">utility methods</a> like <a href="https://gsap.com/docs/v3/GSAP/UtilityMethods/interpolate()">interpolate()</a>, <a href="https://gsap.com/docs/v3/GSAP/UtilityMethods/mapRange()">mapRange()</a>, most of the <a href="https://gsap.com/docs/v3/Eases">eases</a>, and it can do snapping and modifiers.

```javascript
// typical import
import gsap from "gsap";

// get other plugins:
import ScrollTrigger from "gsap/ScrollTrigger";
import Flip from "gsap/Flip";
import Draggable from "gsap/Draggable";

// or all tools are exported from the "all" file (excluding members-only plugins):
import { gsap, ScrollTrigger, Draggable, MotionPathPlugin } from "gsap/all";

// don't forget to register plugins
gsap.registerPlugin(ScrollTrigger, Draggable, Flip, MotionPathPlugin); 
```

The NPM files are ES modules, but there's also a /dist/ directory with <a href="https://www.davidbcalhoun.com/2014/what-is-amd-commonjs-and-umd/">UMD</a> files for extra compatibility.

## GSAP is FREE!

Thanks to [Webflow](https://webflow.com), GSAP is now **100% FREE** including ALL of the bonus plugins like [SplitText](https://gsap.com/docs/v3/Plugins/SplitText), [MorphSVG](https://gsap.com/docs/v3/Plugins/MorphSVGPlugin), and all the others that were exclusively available to Club GSAP members. That's right - the entire GSAP toolset is FREE, even for commercial use! 🤯  Read more [here](https://webflow.com/blog/gsap-becomes-free)

### ScrollTrigger &amp; ScrollSmoother

If you're looking for scroll-driven animations, GSAP's <a href="https://gsap.com/docs/v3/Plugins/ScrollTrigger/">ScrollTrigger</a> plugin is the standard. There's a companion <a href="https://gsap.com/docs/v3/Plugins/ScrollSmoother/">ScrollSmoother</a> as well.

### Using React?

There's a <a href="https://www.npmjs.com/package/@gsap/react">@gsap/react</a> package that exposes a `useGSAP()` hook which is a drop-in replacement for `useEffect()`/`useLayoutEffect()`, automating cleanup tasks. Please read the <a href="https://gsap.com/react">React guide</a> for details.
