Hello Carl,
Thank you for your answer, I understand better now ! I'll try to play with the different option to maybe pause the animation while scrolling or find anything else !
And for the marginTop, I'm using it because on the real project, I already have some transform properties, and they were conflicting with the gsap x, y, z and rotate, I assumed it was normal behavior, but if you have a tips for that I could appreciate it !
Thanks again for your answer,
Have you a good day !
