# Less

Unclassified · [Official website](https://lesscss.org)

Less is an open-source CSS preprocessor that extends CSS with variables, mixins, nesting and functions, and compiles to standard CSS. It is usually compiled at build time, though a browser version can compile stylesheets on the page. It is a styling tool, not a tracking service, and does not set cookies or send visitor data to a third party.
