Have a look at this answer. The layout is working well but I am trying to have my implementation have a scrollbar that occupies 100% of the page(100vh). If you look at the answer's scrollbar it occupies the full height minus the header's and footer's part. How can I have a scrollbar that occupies 100% of the page?
I have tried putting the height of the scrollbar to 100vh using this sandbox, but it didn't work.
Is what I am trying possible using flexbox, if so how do I do it?
