PostCSS Short Size lets you use size properties to represent width and
height in CSS, following the 1-to-2 syntax.
.image {
size: 100px;
}
.video {
max-size: 400px 300px;
}
/* becomes */
.image {
width: 100px;
height: 100px;
}
.video {
max-width: 400px;
max-height: 300px;
}
The supported properties are size, min-size, and max-size.
Usage
Add PostCSS Short Size to your project:
npm install postcss-short-size --save-dev
Use PostCSS Short Size to process your CSS:
const postcssShortSize = require('postcss-short-size');
postcssShortSize.process(YOUR_CSS /*, processOptions, pluginOptions */);
Or use it as a PostCSS plugin:

}
/* becomes */
.image {
width: 100px;

The skip option defines the skip token used to ignore portions of the
shorthand.
postcssShortSize({ skip: '-' });
