I’m using the Image Columns block with 3 columns. On desktop or tablet, they look great. On mobile they shrink to two tall narrow columns side by side with a similarly tall narrow column underneath. There’s an example on this page on my site (immediately under where it says “It is important to know”).
Is it possible to get them to stack on mobile? I think they’d look so much better if they stacked with each column taking up the full mobile screen width, instead of displaying as 2+1 really narrow columns.
