Analyse CSS stylesheet usage for a webpage, either locally or remotely. See how your stylesheet's CSS selectors are used in a page to aid with optimising your CSS.
CSSScan will let you check the usage of selectors for all stylesheets referenced from a single page. Future releases will allow link-scraping to check n levels of links from an initial page.
CSSScan uses Fizzler to perform its actual CSS style matching. Currently Fizzler does not support all CSS3 selectors, particularly pseudo-selectors such as not. Selectors in your stylesheets that cannot be matched by Fizzler are flagged in your results.
