				// notes to myself: once I used an accordion nested in another one there occured problems with setting the width of the nested ones because there were already hidden and had a width of 0 due to that. that's why I'm using this:

				// setting a width prevents bumpy ending of slide transition
				// this is the only part that actually requires jQ 1.4 :-(
