-## How it works
+## Margin and padding
 
 Assign responsive-friendly `margin` or `padding` values to an element or a subset of its sides with shorthand classes. Includes support for individual properties, all properties, and vertical and horizontal properties. Classes are built from a default Sass map ranging from `.25rem` to `3rem`.
 
-## Notation
+Using the CSS Grid layout module? Consider using [the gap utility](#gap).
+
+### Notation
 
 Spacing utilities that apply to all breakpoints, from `xs` to `xxl`, have no breakpoint abbreviation in them. This is because those classes are applied from `min-width: 0` and up, and thus are not bound by a media query. The remaining breakpoints, however, do include a breakpoint abbreviation.

+## Gap
+
+When using `display: grid`, you can make use of `gap` utilities on the parent grid container. This can save on having to add margin utilities to individual grid items (children of a `display: grid` container). Gap utilities are responsive by default, and are generated via our utilities API, based on the `$spacers` Sass map.

+</div>
+{{< /example >}}
+
+Support includes responsive options for all of Bootstrap's grid breakpoints, as well as six sizes from the `$spacers` map (`0`–`5`). There is no `.gap-auto` utility class as it's effectively the same as `.gap-0`.
