How to create hover hide code?

I am trying to figure out how to create a hover hide for my light boxes that I have for buttons that are on this home page below. (the hexagon image has buttons and each of those are linked to a lightbox. I want to be able to hover the mouse over any of those buttons to pull up the lightbox that it is linked to it with just a hover to show. Any ideas? thanks! https://sandyclifton2.wixsite.com/lucdscratch

Also, how would this work on mobile?
