PostCSS Color Functional Notation 
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:
npm install postcss-color-functional-notation --save-dev
Use PostCSS Color Functional Notation to process your CSS:
const postcss = require('postcss');
const postcssColorFunctionalNotation = require('postcss-color-functional-notation');
postcss([
postcssColorFunctionalNotation(/* pluginOptions */)
]).process(YOUR_CSS /*, processOptions */);
PostCSS Color Functional Notation 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 functional color notation
is preserved. By default, it is not preserved.
postcssImageSetFunction({ preserve: true })
