I liked the pattern of the code you used for the intro animation on greensocks.com, so I'm trying to use it.   You have a main timeline and multiple nested timelines added at a certain offset. I did the same thing, except I'd like to add a timeline at a specific label, rather than a time offset.   I'm using this code: var main = new TimelineLite(); main.add(timelineA()); main.add(timelineB(),'labelFromTimelineA'); function timelineA () {  var tl = new TimelineLite();     tl.to('#redBox'
