What it does

GreenSock's official skill for gsap.timeline(): the position parameter (absolute, relative and label-based), labels, timeline defaults and constructor options, nesting child timelines, and playback control including seeking with tl.time() and tl.progress(). Its best practices favour one timeline and the position parameter over chained delays. A paused timeline that the renderer seeks frame by frame is how HyperFrames turns GSAP into video, so pair this skill with the HyperFrames skill when choreographing scenes.

Use when

• Sequencing or choreographing multi-step animation
• Placing tweens with the position parameter or labels
• Nesting scene timelines inside a master timeline
• Seeking a timeline to an exact time or progress

Not for

• Single tweens and eases (use GSAP Core)
• Scroll-driven timelines (GSAP's ScrollTrigger skill)

Install
