Build a Technical Documentation Page scrolling on page

only part of my scrolling is working I can’t see why.

chrome

User Agent is: Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.86 Safari/537.36.

Link to the challenge:

Remove both overflow and overflow-y

If i do that i won’t be able to apply it to my page. i need my left column to stay hidden and my main body to scroll. and that is what i coded. but only one section in the body received the code.

I added height to body and overflow to main (not .main-section).

this what I’ve been saying scrolling isn’t working for me. I’ve read about it and this is suppose
to work.

this just awful I need help I can’t move on anybody.

I looked at your project, but not exactly sure what problem you are having. It appears to be working for me, so maybe you can provide more context or explain how to reproduce the issue you are seeing?
