+# sanitize.css [
][sanitize.css]
+
+[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()`.
