Browser support
Supported browser floors and the progressive material fallback.
The repository's current browserslist is the source of truth:
| Browser | Minimum |
|---|---|
| Safari | 17.5 |
| iOS Safari | 17.5 |
| Chrome | 123 |
| Edge | 123 |
| Firefox | 121 |
These floors cover the CSS features used by the public packages, including light-dark(), backdrop-filter, container queries, and CSS nesting.
Material rendering is progressive. Browsers that cannot apply the complete SVG filter path still receive the backdrop frost and static specular treatment. Component semantics and state do not depend on the richer optical path.
Transpilation does not polyfill CSS rendering features. If an application supports older browsers, provide its own compatibility policy and test the resulting fallback before shipping.
