SCSS is an R6RS Scheme library for parsing, querying, and emitting style information compatible with the W3C Cascading Stylesheets recommendation. While SCSS does not itself provide any rendering functionality, it can provide style information to applications and libraries that do. SCSS includes a pluggable API for arbitrary document implementations that allows it to accomodate the full range of selector types described in the W3C recommendation; SDOM is supported out-of-the-box.
