How to implement smooth page-by-page scrolling?
Well, there is no page scrolling on your link. I didn’t poke around in the source, but there is just animation of elements when entering the viewport.
To animate elements as you scroll, you can use WOW or Sal, or even GSAP.
For page-by-page scrolling, I would not recommend Fullpage. It is written in a very ancient way, the author does not respond to inquiries and criticism, and lives in yesterday. It took a lot of time to make his vintage layout with a relatively new site, and not all of its functionality was needed.
Now I would write myself a simple browser of what is in the viewport with auto-scrolling to the window border, and that's all.Anonymous
To place the code, please use CodePen or similar tool. Thanks you!
