How It WorksLess
Overview
Compiles Less locally in your browser — resolving variables, nested selectors, mixins, and built-in functions into standard CSS — then outputs a minified version. No Node.js build pipeline or Less CLI install required to go from Less to production-ready CSS. All processing happens locally in your browser, so nothing ever leaves your device.
