sanitize.css is a CSS library that provides consistent, cross-browser default styling of HTML elements alongside useful defaults.
sanitize.css is developed alongside normalize.css, which means every normalization is included, and every normalization and opinion are clearly marked and documented.
sanitize.css wraps styles in zero-specificity selectors using :where().
