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

Add PostCSS Gap Properties to your project:
npm install postcss postcss-gap-properties --save-dev
Use PostCSS Gap Properties as a PostCSS plugin:
import postcss from 'postcss';
import postcssGapProperties from 'postcss-gap-properties';
postcss([

remain in the CSS. By default, the original declaration is preserved.
