Collection List columns leaving gaps on mobile

Why does my collection list render these gaps in red on mobile?

I have no such gaps on desktop:

thank you!!

Hi Peter, I can’t see the same when I look at the preview for mobile screen size. No gaps at my end. Have you solved the problem?

In any case, my thinking was that the reason for your issue is a setup with different height inline-block elements. Instead I’d recommend using a grid layout.
