A spacer is a blank tile. It is used only for layout purposes to affect the size and layout of adjacent tiles. To ensure consistency with other dialog boxes, use spacer tiles only in special cases, because the PDB feature handles spacing automatically. See Adjusting the Layout of Dialog Boxes.

The spacer tile has no additional attributes beyond the standard layout attributes.
