147 *
148 * * `before`: the space symbols before the node. It also stores `*`
149 * and `_` symbols before the declaration (IE hack).
150 * * `after`: the space symbols after the last child of the node
151 * to the end of the node.
152 * * `between`: the symbols between the property and value
153 * for declarations, selector and `{` for rules, or last parameter
154 * and `{` for at-rules.
155 * * `semicolon`: contains true if the last child has
156 * an (optional) semicolon.
157 * * `afterName`: the space between the at-rule name and its parameters.
158 * * `left`: the space symbols between `/*` and the comment’s text.
