This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
Summary
The grid-column-gap CSS property specifies the gutter between grid columns.
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.
