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.
Note that grid-column-gap
is an alias for this property.
/* 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: revert; column-gap: revert-layer; column-gap: unset;
The column-gap
property is specified as one of the values listed below.

. For all other layout types it is 0.
