Fixed position item not fixed and not breaking out of the page flow

[Park (haneul)]

I also came across a similar problem.
May I know which one line of JQuery code to use?

My problem is in the link below.

Position-fixed elements that are cms content are not fixed

When you hover over a thumbnail on the main website of the website, you want the project information to be displayed fixedly at the bottom. I want the position of the information to be fixed even when scrolling. [스크린샷 2021-07-17 18.43.15] This is what I want view.

Please help. Thank you.
