Columns width gets too small

[hery]

Hello, CSS newbie here.

When I build a row with e.g. 3 columns and resize down the width of my window, the columns width becomes too small. I would rather have my column stack earlier on top on each other and conserve a minimum width.

When I set a min-width for my columns, I sort of get that behavior, since the columns won't shrink in width too much, but they lose their alignment.

Is there a way to do that? i.e. to have 3 columns at full window size, which don't shrink or lose their alignment when the window width gets smaller, but stack responsively right away?

Thanks!

Amazium does that out-of-the-box, while I've been hacking for hours on Skeleton to get it to work. Skeleton also seems not maintained anymore.
