Emacs support for LESS CSS (lesscss.org)
This package contains less-css-mode.el, which provides an Emacs mode for LESS CSS (lesscss.org), complete with support for compile-on-save.
Deprecation notice: this package is now included in Emacs core, so users of recent Emacs versions will not need to install it separately. This standalone version will not be maintained separately.
If you'd like Emacs to make your browser magically reload your LESS stylesheets, consider using skewer-less.
Please see documentation in less-css-mode.el
