WCF 2.1.x - CSS#
The LESS compiler has been in use since WoltLab Community Framework 2.0, but was replaced with a SCSS compiler in WoltLab Suite 3.0. This change was motivated by SCSS becoming the de facto standard for CSS pre-processing and some really annoying shortcomings in the old LESS compiler.
The entire CSS has been rewritten from scratch, please read the docs on CSS to learn what has changed.
