     *
     * * `before`: the space symbols before the node. It also stores `*`
     *   and `_` symbols before the declaration (IE hack).
     * * `after`: the space symbols after the last child of the node
     *   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.
     * * `ownSemicolon`: contains `true` if there is semicolon after rule.
     *
     * 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' }
