Section scrolling effects

Pardon me if this is obvious thing but I am new to Webflow and I am looking to create s simple 1 page site. I would like each section to take up the entire viewport as you scroll. I found this sample and liked the transition between sections.

Here is another example:

How does one create this transtion between sections? I am looking to anchor the current background and then, on scroll, either have the next background cover the previous, or in the case of this example, the first section background fades into the second section.

Thanks for the help!
