Sass is a meta-language on top of CSS that’s used to describe the style of a document cleanly and structurally, with more power than flat CSS allows. Sass both provides a simpler, more elegant syntax for CSS and implements various features that are useful for creating manageable stylesheets.
The Sass Team
Sass was originally created by Hampton Catlin, and he wrote a proof-of-concept implementation. However, now he just occasionally consults on language issues. Hampton lives in Jacksonville, Florida and is the lead mobile developer for Wikimedia.
Nathan Weizenbaum is the primary maintainer and designer of Sass. His hard work has kept the project alive by endlessly answering forum posts, fixing bugs, refactoring, finding speed improvements, writing documentation, implementing new features, and planning the future of the language. Nathan lives in Seattle, Washington and, while not being a student at the University of Washington he consults for Unspace Interactive or interns at various software companies.
