Split screen scroll

as ever - apologies if this is covered elsewhere, its a tricky idea to search for!

im trying to build something like this: https://kmru.info/abstractions

so two columns. nav on the left fixed and full screen height, content on the right scrolls and can have content of any size.

any ideas?
