  # Represents an HTML element
  # 
  # == 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:
  # 
  #   r = Row.new
  #   r[:style] = 'display: none;'
  # 
  # or for a cell:
  # 
  #   c = Cell.new
  #   c[:style] = 'display: none;'
