How to fix a gallery grid to 3 columns (it defaults to 2 columns on mobile devices)

I have a gallery which I would like to restrict to a 3-column grid, regardless of the screen resolution and aspect ratio. This is something I would ideally be applying to one particular page, rather than across the entire site (although currently I'm not using a grid-style gallery on any other pages). Anyone know how to do this simply?

I'm using Squarespace 7.0 on the legacy plan.

cheers 🙂
