column-gap
The column-gap property is used to specify the amount of space between adjacent columns in a multi-column layout. It specifies the space—or gap—between columns belonging to the same multi-column element.
Trivia & Notes
The height of the column gap is the same height as the height of the columns.
If there is a column rule between columns (which is a line drawn between the columns to set them apart visually), the rule is drawn in the middle of the gap, and it does not take up any space, which means that it will not add to the amount of space between columns specified using column-gap.
If the width and count of columns do not fit into the width of the element, the browser will make necessary adjustments and may reduce the column count to fit the specified column widths into the element. The column gap may also result in narrowing columns down, depending on the amount of space available.
