I feel bad asking, as so many others already have. But despite trying pretty much all of the code that you've provided in this thread, I'm not seeing any change on the mobile version - still just single stacked images on mobile. I'm not sure if it's different for me because I'm not dealing with a gallery, but actually 6 separate images (that I'm using as buttons that link to a filtered directory). Hoping to adjust to 2 or 3 wide instead of just single wide when viewed on mobile.

So grateful if you have a fix suggestion. Thank you 🙂
