Defined in:
lib/less2sass/less/tree/value_node.rb

Overview

Represents the value of any Less AST node.

It has no individual representation in Sass, so it returns its value node’s Sass representation, when #to_sass gets called.

Sass equivalents:

- {::Sass::Script::Tree::Literal} if part of property declaration
- {::Sass::Script::Tree::ListLiteral} if part of variable definition
