Create page with vertical scroll/elements

Hi everyone, I would like to create something like this: link, a “vertical” homepage.
Is it possible? I’m using Generate Press and Elementor Pro.
I do not know exactly how is called so I cannot really find anything online – If someone can address me would be very appreciated.
Also I really like this “plus” icons that open pop-ups, do you know if it was use a plug in to do this?
Many thanks in advance.
