PostCSS Unset Value

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

```pcss .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 | Create React App | Gulp | Grunt | | --- | --- | --- | --- | --- | --- |

Options

preserve

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

js postcssUnsetValue({ preserve: true })

```pcss .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; } ```
