PostCSS Unset Value
PostCSS Unset Value lets you use the unset keyword, following the CSS Cascading and Inheritance specification.
.color {
color: unset;
}
.border-color {
border-color: unset;
}
.margin {
margin: unset;
}
/* becomes */
.color {
color: inherit;
}
.border-color {
border-color: initial;
}
.margin {
margin: initial;
}
Usage
Add PostCSS Unset Value to your project:
npm install postcss @csstools/postcss-unset-value --save-dev
Use it as a PostCSS plugin:
const postcss = require('postcss');
const postcssUnsetValue = require('@csstools/postcss-unset-value');
postcss([
postcssUnsetValue(/* pluginOptions */)
]).process(YOUR_CSS /*, processOptions */);
PostCSS Unset Value runs in all Node environments, with special instructions for:
Node | PostCSS CLI | Webpack | Create React App | Gulp | Grunt |

option determines whether the original source
