grid-row-gap

The grid-row-gap CSS property specifies the gutter between grid rows.

The effect is as though the affected grid lines acquired width: the grid track between two grid lines is the space between the gutters that represent them. For the purpose of track sizing, each gutter is essentially treated as an extra track of the specified length. Negative values are invalid.
