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.

This is what I want view. (Image scrolls, but information only appears when hovered from a fixed position)

But I don’t know for what reason. It is not fixed, so if you scroll, the information will not be visible. I tried to set the position by separating the image and information cms collection, but when I hovered it, the function to show the information did not work.

Please help.
