PostCSS Selector Not

PostCSS Selector Not transforms :not() W3C CSS level 4 pseudo classes to :not() CSS level 3 selectors following the Selectors 4 Specification.

```pcss p:not(:first-child, .special) { color: red; }

/ becomes /

p:not(:first-child):not(.special) { color: red; } ```

⚠️ Only lists of simple selectors (:not(.a, .b)) will work as expected. Complex selectors (:not(.a > .b, .c ~ .d)) can not be downgraded.

Usage

Add PostCSS Selector Not to your project:

bash npm install postcss postcss-selector-not --save-dev

Use it as a PostCSS plugin:

```js const postcss = require('postcss'); const postcssSelectorNot = require('postcss-selector-not');

postcss([ postcssSelectorNot(/ pluginOptions /) ]).process(YOUR_CSS /, processOptions /); ```
