Sass is a stylesheet language that’s compiled to CSS. It allows you to use [variables](/documentation/variables), [nested rules](/documentation/style-rules#nesting), [mixins](/documentation/at-rules/mixin), [functions](/documentation/functions), and more, all with a fully CSS-compatible syntax. Sass helps keep large stylesheets well-organized and makes it easy to share design within and across projects.

• If you're looking for an introduction to Sass, check out the tutorial.

• If you want to look up a built-in Sass function, look no further than the function reference.

• If you're calling Sass from JavaScript, you may want the JS API documentation.

• Or the Dart API documentation if you're calling it from Dart.

• Otherwise, use the table of contents for the language reference!
