[css-multicol][css-scroll-snap] Snapping to columns

[frivoal]

If a multicol is (in) a scroll snap container, is there a way to snap to columns, or to rows of columns? I don't believe current specifications say so anywhere.

I suspect a way to approach this would be to add a column value to scroll-snap-align (combinable with start | end | center to let an element create snap positions not on itself, but on the columns in generates.

Or maybe we should generalize some more, and have the same mechanism enable a grid to declare snap positions on its rows/columns as well?

If I read this correctly, the WG has resolved to add a ::column pseudo for this purpose?

RESOLVED: Add ::column pseudo, as a leaf node on the multicol, supporting scroll-marker and scroll-snap-align

It does not solve the issue for grid rows/columns though, if you want to snap to the possibly empty row/column and not the items.
