sanitize.css is a CSS library that corrects broken and missing styles in all browsers, preserving useful defaults rather than unstyling everything. It’s developed alongside normalize.css, so every normalization includes the browsers or browser versions being targeted, and every opinionated change is marked and documented.
I heard about this when listening to an episode of ShopTalkShow. I’ve recently been using both reset.css and normalize.css (not on the same projects, obviously), but this looks like it warrants further investigation. See the GitHub page for details of the opinionated differences.
