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

CSS Grid Layout initially defined the grid-row-gap property. This prefixed property will be replaced by row-gap, however in order to support browsers that implemented grid-row-gap and not row-gap for grid, you will need to use the prefixed property as in the interactive example above.


/* <length> values */
row-gap: 20px;
row-gap: 1em;
row-gap: 3vmin;
row-gap: 0.5cm;

/* <percentage> value */
row-gap: 10%;

/* Global values */
row-gap: inherit;
row-gap: initial;
row-gap: unset;


Is the width of the gutter separating the rows. <percentage> values are relative to the dimension of the element.

Formal syntax

normal | <length-percentage>

<length-percentage> = <length> | <percentage>
