Defined in:
lib/sass/tree/directive_node.rb,
lib/sass/css.rb

Overview

A static node representing an unproccessed Sass @-directive. Directives known to Sass, like @for and @debug, are handled by their own nodes; only CSS directives like @media and @font-face become DirectiveNodes.

@import is a bit of a weird case; it becomes an ImportNode.
