Hi
Thank you for your super fast and thorough answer and solution. Will have to adapt the rest of the DOM to target children.
I wasn’t aware that triggers shouldn’t be animated.
On a side note, you commented that "GSAP is smart and it will just animate to the default". Well, not really in my case, as when I add a second scrollTrigger for when the items leave the page, skewing again in the opposite direction, the transform will not start from the default, but from the skew defined in 'from'. And I don’t think I can fit the whole thing in a timeline, as I need to control precisely the area in witch there is no transform (skew:0).
Best
