grid-column-gap

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

Initially a part of Multi-column Layout, the definition of column-gap has been broadened to include multiple layout methods. Now specified in Box Alignment, it may be used in Multi-column, Flexible Box, and Grid layouts.

Syntax

/* Keyword value */
column-gap: normal; 

/* <length> values */
column-gap: 3px;
column-gap: 2.5em;

/* <percentage> value */
column-gap: 3%;

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

The column-gap property is specified as one of the values listed below.

Values

normal
The browser's default spacing is used between columns. For multi-column layout this is specified as 1em. For all other layout types it is 0.
<length>
The size of the gap between columns, defined as a <length>. The <length> property's value must be non-negative.
<percentage>
The size of the gap between columns, defined as a <percentage>. The <percentage> property's value must be non-negative.

Formal definition

Initial value normal
Applies to multi-column elements, flex containers, grid containers
Inherited no
Percentages refer to corresponding dimension of the content area
Computed value as specified, with <length>s made absolute, and normal computing to zero except on multi-column elements
Animation type a length, percentage or calc();

Formal syntax

normal | <length-percentage>
where 
<length-percentage> = <length> | <percentage>
