Here at Factotum we’ve been using LESS for a couple of years to create websites on the for fly for eziCONEX.com. LESS stands for Leaner CSS. It is a dynamic stylesheet language designed by Alexis Sellier that is influenced by Sass and has influenced the newer “SCSS” syntax of Sass, which adapted its CSS-like block formatting syntax.
LESS provides the following mechanisms: variables, nesting, mixins, operators and functions; the main difference between LESS and other CSS pre-compilers being that LESS allows real-time compilation via LESS.js by the browser. LESS can run on the client-side and server-side or can be compiled into plain CSS.
I think we’ll be seeing more of LESS in the future.
