Nothing that a transform(90deg) cannot solve :-).

More seriously, what you describe is quite doable with flexbox (flex-direction: row, flex-wrap: wrap and flex-grow: 1).

Interestingly, even the Masonry layout was already doable using a simple multi-column layout, the "only" issue is that instead of having the items left-to-right, top-to-bottom (ordered by row) you have them top-to-bottom, left-to-right (ordered by column) which is not what you want most of the times

There's a CMS I use that has a photo search option. It loads in images in a column ordered masonry layout, which when you scroll down adds new images to the columns, so all the pictures move about and you've no idea where you are.

It's infuriating.
