PostCSS Short Overflow lets you write overflow-x and overflow-y with the overflow shorthand in CSS.

html {
  overflow: hidden auto;
}

[contenteditable] {
  overflow: * auto;
}

/* becomes */

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

[contenteditable] {
  overflow-y: auto;
}

Usage

Add PostCSS Short Overflow to your project:

npm install postcss-short-overflow --save-dev

Use PostCSS Short Overflow to process your CSS:

const postcssShortOverflow = require('postcss-short-overflow');

postcssShortOverflow.process(YOUR_CSS /*, processOptions, pluginOptions */);

Or use it as a PostCSS plugin:

const postcss = require('postcss');
const postcssShortOverflow = require('postcss-short-overflow');

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

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

Options

prefix

The prefix option defines a prefix required by properties being transformed. Wrapping dashes are automatically applied, so that x would transform -x-overflow.

postcssShortOverflow({ prefix: 'x' });

html {
  -x-overflow: hidden auto;
}

/* becomes */

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

skip

The skip option defines the skip token used to ignore portions of the shorthand.

postcssShortOverflow({ skip: '-' });

[contenteditable] {
  overflow: - auto;
}

/* becomes */

[contenteditable] {
  overflow-y: auto;
}
