UnCSS is a tool that removes unused CSS from your stylesheets. It works across multiple files and supports Javascript-injected CSS.
The process by which UnCSS removes the unused rules is as follows:
- The HTML files are loaded by jsdom and JavaScript is executed.
- All the stylesheets are parsed by PostCSS.
- document.querySelector filters out selectors that are not found in the HTML files.
- The remaining rules are converted back to CSS.
This is free and open source software.
