• A dynamic preprocessor style sheet language that can be compiled into Cascading Style Sheets (CSS) and run on the client or server side. The indented syntax of Less is a nested meta-language, as valid CSS is valid Less code with the same semantics. Less provides variables, nesting, mixins, operators, and functions. The main difference between Less and other CSS precompilers is that Less allows real-time compilation via less.js by the browser. Less was first released in 2009. ← Wikipedia ↑ lesscss.org
