1 column view on mobile for Gallery

Site URL: https://www.spawellness.com/projects

Hi, 

Hoping to find someone who can help with code so this gallery block (which is 3 column wide on a desktop/tablet) converts to only 1 column when viewed on a mobile device. 

Currently it displays as 2 column on a mobile, but I only want it 1 column so it is the full width of a mobile device. 

Thanks!!!!
