#Introduction

The gap CSS shorthand property sets the gaps (gutters) between rows and columns in flexible box layout and grid layout.

This property is a shorthand for the following CSS properties: row-gap and column-gap, 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>.
