@mvaneijgen thank your for responding, this is the link for stackbliz https://stackblitz.com/edit/react-xogadh?file=src%2FApp.js.
so basically of demo i shared, when we scrolling and enter the banner section the letter appear one by one as we still scrolling down this section. do you think is possible to change from scrolltrigger to observer and still have the same result?
Thank you!
