Help to code to show image info below gallery page, in grid design, Rally template/Brine

Site URL: https://www.studioksr.com/

Hi,

I have several existing pages set up with gallery blocks that show the title/caption of the image in the grid: https://www.studioksr.com/paintings   I like the layout a lot, but I would like to start using categories and tags. my site is based on the Rally Template in the Brine Family.

So I need to change to gallery page instead of gallery block. But the image caption does not appear in the grid design-- it only shows in the lightbox after a viewer clicks on an image.

Here is my unpublished gallery page that I am experimenting with: https://www.studioksr.com/gal-cats

I'm hoping to find some custom CSS that I can add to the new gallery block page that would force the text to show in the grid -- ideally below the image like it appears here  https://www.studioksr.com/paintings

Thanks for any suggestions!
