Hi @OSUblake! Thanks for the quick reply!
I understand the confusion as the project is in the beginning stages. However, my goal is to replicate the behavior of Gamer Moms. The reason why it's working in my codepen is because, like you said, ScrollSmoother is overtaken by CSS and is not smoothing at all. Once I iron out this issue I plan to add numerous ScrollTrigger animations once the sections are reached and snapped to. Does that make sense? Here is the mockup if that helps. I could be going about this all wrong, but my plan was to use the smoother to make the transitions and animations less choppy for ScrollTrigger.
