  // Second parameter: whether to hide, show or reverse the current status of the object.
  //   Values are: 'hidden', 'visible', 'reverse'
  //   Second param is optional if a third parameter is not supplied. When left out, the
  //   second param defaults to 'reverse'

  //   the object is visible or not. This uses (for W3C) the display style property.

  //   page. This uses (for W3C) the visibility style propery.
