      # == Modifying HTML options
      # 
      # HTML options can normally be specified when creating the element.
      # However, if they need to be modified after the element has been created,
      # you can access the properties like so:
      # 
      #   m = Menu.new
      #   m[:style] = 'display: none;'
      # 
      # or for a menu bar:
      # 
      #   b = MenuBar.new
      #   b[:style] = 'display: none;'
