Change Gallery Photo Layout on Mobile Only

Hello!

Is there a way to display ALL (sitewide) of my gallery block photos in a single column on mobile only, even when my desktop display may be 2-3 columns? In other words, regardless of how many gallery photo columns my desktop view may have, I'd like mobile to always display them in one single column.

I don't know if this is relevant, but my site is soulflower.love and I use the gallery blocks for almost all of my blog posts.

Thank you so much in advance for your time 🙂

Can you share link to some posts where you use gallery? We can check & help easier

My apologies for the delay - for some reason Squarespace isn't notifying me when I'm getting a reply.

Here is a link to a blog post where I use a gallery (scroll to the bottom, below text). It's currently 3 columns (3 photos) wide. I'd like to keep it this way on desktop, but change all gallery photos on mobile to 1 column (1 photo) wide:

Here is another post for reference. This one has a mix of varying column sizes, which I would like to keep as is on the desktop, but again change to a universal single column on mobile.

Do you think this is possible?

Thank you so much!!

Thank you so much, that worked beautifully! 🙏🙏🙏
