LESS (Leaner CSS) is a dynamic stylesheet language designed by Alexis Sellier. It is influenced by Sass and has influenced the newer SCSS syntax of Sass which adapted its CSS-like block formatting syntax. LESS is open-source. Its first version was written in Ruby however in the later versions use of Ruby has been deprecated and replaced by JavaScript. The indented syntax of LESS is a nested metalanguage as valid CSS is valid LESS code with the same semantics.
