Sass 0.1.0
2006 October 5th
Hampton Catlin and Natalie Weizenbaum designed a CSS preprocessor called Sass 0.1.0 (Syntactically awesome style sheets). Sass preprocessor is a scripting language interpreted or compiled into cascading styles. To the CSS syntax, Sass adds variables, mixins, selector inheritance, nesting rules, arithmetic operators, and other features.
