[PostCSS Gap Properties] lets you use the `gap`, `column-gap`, and `row-gap`
shorthand properties in CSS, following the [CSS Grid Layout] specification.

```pcss
.standard-grid {
	gap: 20px;
}

.spaced-grid {
	column-gap: 40px;
	row-gap: 20px;
}

/* becomes */

.standard-grid {
	grid-gap: 20px;
	gap: 20px;
}

.spaced-grid {
	grid-column-gap: 40px;
	column-gap: 40px;
	grid-row-gap: 20px;
	row-gap: 20px;
}
```
