• CSS inheritance is universal so that styles are easier to control (code).
• The box model is more intuitive with border-box (reference) (reference) (code).
• Smaller font-sizes display consistently across browsers (reference) (code).
• Monospace fonts render consistently (reference) (code).
• Border styles work as expected (reference) (code).
• Text selections containing a drop shadow remain legible (reference) (code).
• Content may be hidden from the screen but not screenreaders (reference) (reference) (code).

Sanitize.css styles browsers to render elements more consistently with developer expectations and preferences. Normalize.css styles browsers to render elements more consistently with each other. Reset.css unstyles every element. Each one has its own advantages.

In Sanitize.css, CSS inheritance is assigned universally so that styles cascade naturally and consistently. Wherever possible, the box model operates more intuitively. Every normalization and opinionated default is carefully documented, and most are configurable from Sass.

To give you even more control, sanitize.scss allows you to define your own defaults for box-sizing, font family, text rendering, selection, etc. - all without over-declaring them later.

At present, we support the current and previous major releases of popular web browsers. When a new version is released, we begin supporting that version and stop supporting the third most recent version. Many older browsers happen to be remain supported using the same CSS without additional needs.

Currently tested and supported browsers include Android 4.3-4.4+, Chrome 39-45+, Edge 12+, Firefox 34-40+, Internet Explorer 9-11, iOS 7-8+, Safari 7-9+, Windows Phone 8.1+.
