  🦔 A Webpack plugin to inline your critical CSS and lazy-load the rest.

  

https://github.com/GoogleChromeLabs/critters Might be a good starting point. It’s designed to inline the css afterward so it’s more focused on extracting used css than removing unused.

• uncss

  5 9,388 5.3 JavaScript

  Remove unused styles from CSS

  

Check out: https://github.com/uncss/uncss

I've only used it once but it did the job (NOTE: Plain HTML, plain CSS, no build pipeline. So YMMV)

• purgecss

  51 7,659 8.1 TypeScript

  Remove unused CSS

  

As a starting point, Tailwind used to use PurgeCSS [0] but I'm not sure what they use now.
