Dust-Me Selectors

Finds unused CSS selectors

Dust-Me Selectors is a development tool for Opera and Firefox, that scans HTML pages to find unused CSS selectors.

Available for Opera 11.50 or later, and Firefox 3.5 or later, both versions have the same core features, but each has a different interface to suit the capabilities of its environment. Dust-Me Selectors works by extracting all the selectors from all the stylesheets on the page you're viewing, then analyzing that page to see which of those selectors are not used. The data is stored for each site, 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 list of selectors that are not used on any page.

Main features

• Supports all forms of stylesheet include, and all selectors up to CSS3.
• Includes <link> stylesheets inside IE Conditional Comments.
• Can scan single pages, or spider an entire site, and you can pause and resume the spider at any time.
• Caters for common CSS hacks, for example "* html #foo" will be treated as "html #foo".
• Super-fast processing can now scan up to five pages per second.
