NPM Version CSS Standard Status Build Status Discord

PostCSS Color Functional Notation lets you use space and slash separated color notation in CSS, following the CSS Color specification.

:root {
  --firebrick: rgb(178 34 34);
  --firebrick-a50: rgb(70% 13.5% 13.5% / 50%);
  --firebrick-hsl: hsla(0 68% 42%);
  --firebrick-hsl-a50: hsl(0 68% 42% / 50%);
}

/* becomes */

:root {
  --firebrick: rgb(178, 34, 34);
  --firebrick-a50: rgba(178, 34, 34, .5);
  --firebrick-hsl: hsl(0, 68%, 42%);
  --firebrick-hsl-a50: hsla(0, 68%, 42%, .5);
}

Usage

Add PostCSS Color Functional Notation to your project:

const postcss = require('postcss');
const postcssColorFunctionalNotation = require('postcss-color-functional-notation');

Options

preserve

The preserve option determines whether the original functional color notation is preserved. By default, it is not preserved.

postcssColorFunctionalNotation({ preserve: true })
:root {
  --firebrick: rgb(178 34 34);
  --firebrick-a50: rgb(70% 13.5% 13.5% / 50%);
  --firebrick-hsl: hsla(0 68% 42%);
  --firebrick-hsl-a50: hsl(0 68% 42% / 50%);
}

/* becomes */

:root {
  --firebrick: rgb(178, 34, 34);
  --firebrick: rgb(178 34 34);
  --firebrick-a50: rgba(178, 34, 34, .5);
  --firebrick-a50: rgb(70% 13.5% 13.5% / 50%);
  --firebrick-hsl: hsl(0, 68%, 42%);
  --firebrick-hsl: hsla(0 68% 42%);
  --firebrick-hsl-a50: hsla(0, 68%, 42%, .5);
  --firebrick-hsl-a50: hsl(0 68% 42% / 50%);
}

enableProgressiveCustomProperties

The enableProgressiveCustomProperties option determines whether the original notation is wrapped with @supports when used in Custom Properties. By default, it is enabled.

⚠️ We only recommend disabling this when you set preserve to false or if you bring your own fix for Custom Properties. See what the plugin does in its README.

postcssColorFunctionalNotation({ enableProgressiveCustomProperties: false })
