Need a header sliding plugin

I, I am searching for a plugin or code that makes it possible to slide my header by clicking a Link.
But the header shouldn’t only be a picture but also contains text and divs.

I found this perfect example, that’s exactly what I’d like to have: https://www.sketchtheatre.com/

and that’s my theme where I’d like to use it:
https://blog.stephanskorepa.net/
So the picture and the text to the right should slide away and the next content should be displayed.

Would be great if you could help me ??
Thanks in advance!
