CSS Stats
CSS Stats runs a thorough audit of the CSS files requested on a page. Like many similar tools, it provides a dashboard-alike view of rules, selectors, declarations and properties, along with pseudo-classes and pseudo-elements. It also
breaks down all styles into groups, from layout and structure to spacing, typography, font stacks and colors.

One of the useful features that CSS Stats provides is the
CSS specificity score, showing how unnecessarily specific some of the selectors are. Lower scores and flatter curves are better for maintainability.
