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.
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:
npm install postcss postcss-selector-not --save-dev
Use it as a PostCSS plugin:
const postcss = require('postcss');
const postcssSelectorNot = require('postcss-selector-not');
postcss([
postcssSelectorNot(/* pluginOptions */)
]).process(YOUR_CSS /*, processOptions */);
PostCSS Selector Not runs in all Node environments, with special instructions for:
| Node | PostCSS CLI | Webpack | Create React App | Gulp | Grunt |
