      # In order to pass the CSS as string to super it is necessary to access

      # suitable adaptor (Nokogiri or Hpricot). To make load_html work, an
      # adaptor needs to be included and @options[:with_html_string] needs to be
      # set. For further information, refer to ::Premailer#initialize.
