Usage
Add PostCSS Gap Properties to your project:
npm install postcss-gap-properties --save-dev
Use PostCSS Gap Properties to process your CSS:
import postcssGapProperties from 'postcss-gap-properties';
postcssGapProperties.process(YOUR_CSS /*, processOptions, pluginOptions */);
Or use it as a PostCSS plugin:
import postcss from 'postcss';
import postcssGapProperties from 'postcss-gap-properties';
postcss([
postcssGapProperties(/* pluginOptions */)
]).process(YOUR_CSS /*, processOptions */);
PostCSS Gap Properties runs in all Node environments, with special instructions for:

Options
preserve
The preserve option determines whether the original gap declaration should
remain in the CSS. By default, the original declaration is preserved.
