         * Every parser saves its own properties,
         * but the default CSS parser uses:
         *
         * * `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.
         * * `afterName`: the space between the at-rule name and its parameters.
         *
         * PostCSS cleans at-rule parameters 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('  @media\nprint {\n}')
         * root.first.first.raws //=> { before: '  ',
         *                       //     between: ' ',
         *                       //     afterName: '\n',
