         * * `before`: the space symbols before the node. It also stores `*`

         *   to the end of the node.
         * * `between`: the symbols between the property and value
         *   for declarations, selector and `{` for rules, or last parameter
         *   and `{` for at-rules.
         * * `semicolon`: contains true if the last child has
         *   an (optional) semicolon.
         *
         * PostCSS cleans selectors from comments and extra spaces,
         * but it stores origin content in raws properties.
         * As such, if you don’t change a declaration’s value,
         * PostCSS will use the raw value with comments.
         *
         * @example
         * const root = postcss.parse('a {\n  color:black\n}')
         * root.first.first.raws //=> { before: '', between: ' ', after: '\n' }
