If you are talking about Artisteer > Header > Insert > Position
which creates a control-id box in header then it allow you to:
Wordpress (align your widget where you wanted to show in your header)
Joomla (create a new position where you can place your modules).
you can change the default name of the control-id to something you wanted to work on, then add css to that div to control the look of this portion in header.
