Andrew NicolsCompiling LESS -------------- If you want to make changes to the .css generated from these .less files then you need to use a less compiler to build your changes. The supported way to achieve this is using grunt. See https://docs.moodle.org/dev/Grunt for details of how to install grunt. Once grunt is installed run the 'css' task: $ grunt css And the css files will be compiled. For further info see: https://docs.moodle.org/dev/LESS
