Wondering how to hide an element

[FileBrute]

Hello, my forums will have alot of nodes, and descriptions i want to be able to hide the descriptions and make it popup when you hover over it as its messy for example

Turn that into something like this

But is it possible to do this using the same style

FileBrutelet the community know what you did.
I guess some template modifications or css styling
