		HINWEIS: Ist eine DTD vorhanden, geben die jh(document).height/width Funktionen manchmal nicht korrekte Werte zurück.
		Grund ist, dass margin-bottom beim letzten element und <p>&nbsp;</p> am Seitenende nicht einbezogen werden.
		Um fehlberechnungen zu vermeiden, ist es entweder sinnvoll, auf diese ganz zu verzichten oder
		am Seitenende ein <span style="visibility:hidden;">&nbsp;</span> zu haben.
