Modernizr

San Francisco, California, United States

Modernizr is an open-source feature detection library that identifies browser support for HTML, CSS, and JavaScript features and allows websites to adapt accordingly.

It enables developers to detect supported browser features at runtime, apply progressive enhancement, load polyfills only when required, and provide fallbacks for unsupported features.

Modern browsers now provide broad support for the features Modernizr was designed to detect, so it is primarily needed for projects that support older browsers.
