The CSS minifier we currently use (clean-css) is not maintained and lacks support for new CSS features. CSSNano is a replacement that supports features we need (primarily container queries). This CL only adds the relevant dependencies, and does not use it. I will do that (and remove clean-css) in a follow-up.

postcss-selector-parser 
Selector parser with built in methods for working with selector strings.
Install
With npm do:
npm install postcss-selector-parser
Quick Start
const parser = require('postcss-selector-parser');
const transform = selectors => {
selectors.walk(selector => {
// do something with the selector
console.log(String(selector))
});
};
const transformed = parser(transform).processSync('h1, h2, h3');
To normalize selector whitespace:
const parser = require('postcss-selector-parser');
const normalized = parser().processSync('h1, h2, h3', {lossless: false});
// -> h1,h2,h3
Async support is provided through parser.process and will resolve a Promise
with the resulting selector string.
API
Please see API.md.
