How do I create a "fill out the blanks" interactive website?

I see this all the time but don’t know what to call it

How do I create something like what these sites have done? A form-like website. Having people interact more by filling out some info. I know how to create a form but how do you structure this to flow from one page to another? Links to these sites below:

Any references, similar Webflow-made sites you can share?
