def initialize(html)
  # In order to pass the CSS as string to super it is necessary to access
  # the parsed HTML beforehand. To do so, the adapter needs to be
  # initialized. The ::Premailer::Adaptor handles the discovery of a
  # 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.
  @options = { :with_html_string => true }
  ::Premailer.send(:include, Adapter.find(Adapter.use))
  doc = load_html(html)

  options = PremailerRails.config.merge(
    :with_html_string => true,
    :css_string       => CSSHelper.css_for_doc(doc)
  )
  super(html, options)
