Don't allow the footer to cover the left panel when scrolling down to the bottom, and make the left panel scrollable down along with the right main panel content.

Hi, I am new and have just started creating a website based on this template.

This academicpages template look nice. But I still like the scrolling style in https://stuartgeiger.com/
Specifically, don't make scrollbar appear for the left panel (where profile pictures, social links, etc. are shown); the left panel can scrolled down along when I am scrolling the right main content part; and don't make the footer to cover the left panel.

How to change the codes to realise this? thanks a lot!
