[Theme: Vantage Premium] Change Website Structure

Hi,

I want to change my website structure as on this page: https://www.caviarmkt.com

I want to have a surface where I can just scroll down and there are always individual pages / categories which fill the entire page and when I click on it I get sent to the page.

Could someone give me the appropriate CSS or can I use a widget/plugin for it?

My Website: https://kevinbaranowski.de
I’m using the Vantage Premium Theme.

Any answers would be appreciated – this is my first WordPress site so I am learning everything. Thanks a lot for a great theme!
