[PostCSS Unset Value] lets you use the unset keyword, following the [CSS Cascading and Inheritance] specification.

``css
.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:

`bash
npm install postcss @csstools/postcss-unset-value --save-dev
`

Use it as a [PostCSS] plugin:

`js
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 | Gulp | Grunt |
| --- | --- | --- | --- | --- |

Options

The preserve option determines whether the original source
is preserved. By default, it is not preserved.

`js
postcssUnsetValue({ preserve: true })
`

`css
.color {
color: unset;
}

.border-color {
border-color: unset;
}

.margin {
margin: unset;
}

/ becomes /

.color {
color: inherit;
color: unset;
}

.border-color {
border-color: initial;
border-color: unset;
}

.margin {
margin: initial;
margin: unset;
}
