I like it. In addition I'd also like that 'max-height: <length>' combined with 'overflow: hidden' would mean we'd stop after the first column container (first row of columns). That may be what is implied but it may be good to call it out.

In the case where you have multiple rows Håkon's proposal states the same styling applies (border, padding, margin) -- would there not be use cases where you'd want a different styling between rows? For example a horizontal rule between rows?

You could accomplish this with a pseudo element (for maximum flexibility) ::column-row-gap [need better name!].

Another thought -- it would seem that the encapsulating DOM element (e.g. a <div>) really wants to "refer" to the all rows; it may be more natural to have a pseudo element ::column-row for which you apply 'max-height: <length>'; you could potentially also allow the ::column-row and ::column-row-gap to accept a ax+b notation (as some other selectors do).

So the <div> with 'column-width' and/or 'column-count' set would implicitly have a pseudo element for each column row and a pseudo element for each gap. If 'max-height', 'overflow' and others are applied to the <div> then it refers to the <div> and not a column row.
