SupportsCSS
supportscss.devSupportsCSS is a JavaScript library for in-browser feature detection of modern CSS capabilities, including selectors, properties, and at-rules. It functions as a successor to Modernizr, applying support-based classes to the DOM and exposing a results object for conditional logic. This tool enables developers to implement progressive enhancement strategies by identifying browser support for cutting-edge CSS features beyond standard @supports queries.
