What problem does it solve? Coordinating multiple animations with chained delays is fragile and hard to maintain. This Skill provides the official GSAP patterns for sequencing tweens with gsap.timeline(), so multi-step animations stay readable, controllable, and easy to adjust. ## Core Features & Use Cases - Timeline creation and defaults: Build timelines with shared defaults (duration, ease) inherited by every child tween. - Position parameter and labels: Place tweens at absolute times, relative offsets, or named labels for precise choreography. - Nesting and playback control: Nest child timelines into a master timeline and control playback with play, pause, reverse, seek, and progress. - Use Case: A landing page needs a hero heading to slide in, an image to fade up 0.2s later, and a button to scale in at the same time. Use a timeline with labels and the position parameter instead of stacking setTimeout or delay values. ## Quick Start Ask the AI to create a GSAP timeline that animates three elements in sequence with shared defaults and a label for the outro section.
