CSS Cleanup
Dust-Me Selectors looks like the killer app for clearing out CSS that your site doesn’t need. We’re using it to quickly cut down the CSS mess on Instructables.
Dust-Me Selectors is a Firefox extension (for v1.5 or later) that finds unused CSS selectors.
It extracts all the selectors from all the stylesheets on the page you’re viewing, then analyzes that page to see which of those selectors are not used. The data is then stored so that when testing subsequent pages, selectors can be crossed off the list as they’re encountered.
You can test pages individually, or spider an entire site, and you’ll end up with a profile of which selectors are not used anywhere.
