[using z index and for each to trigger overlapping of layers...]

Thanks for showing that.   I had missed wrapping the 'p' inside of q().

 

Cheers!

Hi Cassie,  I'm not the OP, but I really liked the simplicity of the codepen you showed.   I have been trying to do something similar but I've been using multiple scrollTriggers instead of a timeline.      I'm wondering how to approach the overlapping text in your demo?   If there was a scrolltrigger on chapter,  it could be set to opacity 0 onLeave or something like that.
