PostCSS Overflow Shorthand

PostCSS Overflow Shorthand lets you use the overflow shorthand in CSS, following the CSS Overflow specification.

html {
  overflow: hidden auto;
}

/* becomes */

html {
  overflow-x: hidden;
  overflow-y: auto;
  overflow: hidden auto;
}

Usage

Add PostCSS Overflow Shorthand to your project:

npm install postcss postcss-overflow-shorthand --save-dev

Use it as a PostCSS plugin:

const postcss = require('postcss');
const postcssOverflowShorthand = require('postcss-overflow-shorthand');

postcss([
  postcssOverflowShorthand(/* pluginOptions */)
]).process(YOUR_CSS /*, processOptions */);

PostCSS Overflow Shorthand runs in all Node environments, with special instructions for:

Node	PostCSS CLI	Webpack	Create React App	Gulp	Grunt

Options

preserve

The preserve option determines whether the original overflow declaration is preserved. By default, it is preserved.

postcssOverflowShorthand({ preserve: false })

html {
  overflow: hidden auto;
}

/* becomes */

html {
  overflow-x: hidden;
  overflow-y: auto;
}
