grid-gap

The gap CSS property sets the gaps (gutters) between rows and columns. It is a shorthand for row-gap and column-gap.

Syntax

/* One <length> value */
gap: 20px;
gap: 1em;
gap: 3vmin;
gap: 0.5cm;

/* One <percentage> value */
gap: 16%;
gap: 100%;

/* Two <length> values */
gap: 20px 10px;
gap: 1em 0.5em;
gap: 3vmin 2vmax;
gap: 0.5cm 2mm;

/* One or two <percentage> values */
gap: 16% 100%;
gap: 21px 82%;

/* calc() values */
gap: calc(10% + 20px);
gap: calc(20px + 10%) calc(10% - 5px);

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

This property is specified as a value for <'row-gap'> followed optionally by a value for <'column-gap'>. If <'column-gap'> is omitted, it’s set to the same value as <'row-gap'>.

<'row-gap'> and <'column-gap'> are each specified as a <length> or a <percentage>.

Values

<length>: Is the width of the gutter separating the grid lines.
<percentage>: Is the width of the gutter separating the grid lines, relative to the dimension of the element.
