My client needs a number of grid galleries. She needs title and description to display on both desktop AND mobile. They could display underneath each item when viewing as a grid OR when viewing in lightbox mode. Right now, there is no way to see the description on mobile in a grid gallery.

Note: You'll see a stacked gallery. My client specifically wants a grid AND to be able to view the details of each piece (title, size, materials, year). 

Also note: Mobile Preview (when editing on desktop) indicates that the title and description should be viewable on mobile, but when you actually use a mobile device there is no way to see this information.

Also note: You can display titles only (not in lightbox) but no description.

Anyone have a line of css that would accomplish this? 

Hi,

Currently It doesn't show under image on desktop. Can you enable on desktop first? We can check mobile easier
