What is Sass?

Sass is an extension of CSS3, adding nested rules, variables, mixins, selector inheritance, and more. It's translated to well-formatted, standard CSS using the command line tool or a web-framework plugin.

What is Less?

Less is a CSS pre-processor, meaning that it extends the CSS language, adding features that allow variables, mixins, functions and many other techniques that allow you to make CSS that is more maintainable, themable and extendable.

What is Compass?

The compass core framework is a design-agnostic framework that provides common code that would otherwise be duplicated across other frameworks and extensions.
