Helium is a browser-based JavaScript tool that scans a list of pages on a website to detect unused CSS selectors across all loaded stylesheets. It generates a report of selectors not found in use on any tested page.
Use cases
- find unused css selectors on my site
- detect dead css across multiple pages
- audit stylesheets for unused rules
- clean up bloated css files
- report which css classes are never used
When to choose
- you want a quick, browser-only audit of unused CSS across many pages of a site
- you prefer a tool with no build step or server-side dependencies
When to avoid
- you need actively maintained tooling or modern CSS feature support
- you want automated CI integration or headless scanning
- you cannot inject a script tag into every page of the site
