Overview

A static node representing an unprocessed 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 and @charset are special cases; they become ImportNodes and CharsetNodes, respectively.
