Adding sections with pages instead of posts

Hello! I'm in love with your WP theme, so first of all, congrats for it. I'm trying to build a simple website with four sections, and I would like them to be part of the #fullscreen, so they skip to the following one when you start scrolling. I have seen that's made automatically with blog posts, but in the case of pages, I can just choose one. I have tried splitting the page into sections with height: 100vh, but that just solves the size, the scroll is gradual and I don't want that. Is there anything I could do being a beginner in js? Thanks a lot! Marta
