Hi Zach, thanks for the welcome and for the answer. Yes, you're totally right. I misspoke, I'm sorry. What i wanna do is not a parallax effect but the effect explained in the ScrollTrigger introduction video. I want to reveal one section in top of each other at the page scrolling. And in one of this fixed section I need to have a sticky element, exactly like in your codepen example. But yes, the issue is that i can't have nested pinning. So I need to find another solution. Thanks again.
