By default the anchor target is the top edge of the container's content area. In layouts with advanced constraints, the target can be a constraint row.
Setting the property to a number or to a numerical string like "10" specifies use of the default anchor target.
To specify an anchor target, set the property value to a string in the format: "anchorTargetName:value". For example, "row1:10".
