      public class UIPlaceholder
      extends AbstractPlaceholder

  Adds placeholder capability to HTML input and textarea elements. A placeholder typically appears as light gray text within an input or textarea element whenever the element is empty and does not have focus. This provides a hint to the user as to what the input or textarea element is used for, or the type of input that is required.
