row-gap

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since October 2017.

The row-gap CSS property sets the size of the gap (gutter) between an element's rows.

Early versions of the specification called this property grid-row-gap, and to maintain compatibility with legacy websites, browsers will still accept grid-row-gap as an alias for row-gap.
