'Elementor: dynamic content on fixed background

My problem: I want to have the content of my page as it is on the https://little-lime.de/ website. So I want the content to be changed when the user just scrolls a little bit while the background stays the same. Is there any Elementor plugin for doing this? Or any other solutions for this?

And the second (less important question): How can I create an background like the one of the mentioned website (https://little-lime.de/) where the points in the background always connect with the mouse?

Hopefully you understand my questions/problems and can halp me.

Thanks in advance!
