How to make it so that when hovering over a block, a brief description appears on the right?

Question

PHP

I'll give you an example. There is a catalog of films, on the selection page there is an image of the film and the title. It is necessary that when you hover over this block on the right, in a separate block, a brief description from the main article of this film appears. Note: I need to figure out how to take the short description from the main article . It may be possible to do this using links and anchors, but I can’t figure out how to implement this.
