I would like to find out on what pages of a website some style elements of a style.css are used? For example, I would like to find out if .view-product {margin: 0} is used on x, y, or z pages of a website.
So far I have used Chrome Developer (Audits) to identify which css rules are not used on particular page, and used diffchecker to check the difference between the full css file, and the Chrome developer audits generated content.
Any other methods?
Thanks.
