# GSAP for the Web

GSAP (GreenSock Animation Platform) is the workhorse for code-driven web motion: sequenced timelines, scroll-driven storytelling, text reveals, and layout transitions. As of GSAP 3.12+, every plugin (ScrollTrigger, SplitText, Flip, MotionPath, MorphSVG, Draggable, Observer) is 100% free, including for commercial use.

## When to use

- Scroll-driven storytelling: pinned sections, parallax, progress scrubbing, horizontal scroll
- Sequenced hero animations and complex multi-element timelines with precise overlap control
- Text reveals split into chars/words/lines (SplitText)
- Layout transitions where an element changes position/size/parent (Flip)
- Any motion needing fine timing control, easing precision, or imperative orchestration
