± I don't understand what's wrong with the current definition, based on your

I've attached a mockup of the design I've in mind: in an inline flow, a photo gallery is designed as a grid (whose items are possibly subgrids so that elements align across items on a row...). This grid doesn't have a definite width (but has a max-width of 100%). That grid is centered and has to contain as many columns as required by the amount of items it contains, with the constraint is has to create a new line once it exceeds its max width.

In fact, this is very similar to a wrapped "flexbox" layout but with alignment constraints which a flexbox layout cannot give you, including "gaps" between elements which require specific empty columns.

To me, the issue is that the cases for which you can use automatic repetition is really too narrow. I would prefer to get something closer to what we have for flexboxes.
