Render elements consistently. Follow best practices.

NPM

npm install --save-dev sanitize.css

Bower

bower install --save sanitize-css

sanitize.css corrects broken and missing styles in all browsers so that elements always render consistently. Next, it adds new default styles based on modern best practices. Finally, it exposes opinionated defaults as governable variables.

*,
::before,
::after {
	box-sizing: inherit;
}

:root {
	box-sizing: var(--root-box-sizing, border-box);
}

Each new default is easily configurable with variables available in your favorite CSS, Less, Sass, SCSS, and Stylus flavors.

sanitize.css styles elements more consistently with developers’ expectations and preferences. normalize.css styles elements more consistently between browsers. reset.css unstyles every element. Both sanitize.css and normalize.css are maintained in sync, and both projects correct browser bugs while carefully testing and documenting every change.

At present, sanitize.css supports the current and previous major releases of common web browsers. When a new version is released, we begin supporting that newer version and stop supporting the third version back. Additionally, many older browsers remain supported without supplementary CSS.

Currently tested and supported browsers include Android 4.3-4.4+, Chrome 47-48+, Edge 12-13+, Firefox 43-44+, Internet Explorer 10-11, iOS 7-8+, Opera 34-35+, Safari 8-9+, and Windows Phone 8.1+.

Additionally tested and supported browsers (requiring no supplementary CSS) include Internet Explorer 9 and Safari 7.

sanitize.css is dedicated to the public domain.
