Less was originally inspired by Sass, with a leaner feature set and a syntax closely matching CSS, which Sass did not have at the time. (Sass was later inspired by Less to create SCSS, its own CSS-like syntax.)
In May 2012 Alexis turned over control and development to a core team of contributors who now manage, fix and extend the language.
Less is maintained by a group of invaluable core contributors, with the massive support and involvement of our community. No one person is in charge and everyone has their own areas and donates the time they can afford. In alphabetical order:
Get involved with Less development by opening an issue or submitting a pull request (if it's a feature request, please open an issue first).
