CSS

Highlights

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).

Differences

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.

Options

To give you complete control, sanitize.css is available in three flavors; CSS, SCSS, and Stylus. Each flavor allows you to define your own defaults for box-sizing, font family, text rendering, selection, etc. - all without over-declaring them later.
