Twitter clone problem

Someone please help me fix my bug here!😩
I basically want the Column-3 to stop scrolling at the end of the footer links while the column-2 still scrolls just as it is on Twitter desktop view.

I know this is achievable using JS but unfortunately for me, I haven’t learnt JS. So is there a way I can get this solution using css alone??

This is my code

I’ve reduced the code as minimum as possible.


It should behave just like this
