Pulldown Menu: Forum Jump, etc - need help

I've got a dark coloured board and i need to change the class on these to make them a darker colour. I thought it would be pretty simple at first but then found out it was a little harder than i first thought.
Tried putting the new css class i made for the pulldown boxes on each tag on the "forumjump" & "forumjumpbit" templates, but to no avail.
I've not seen this changed anywhere else either.
Does anyone happen to know whether it is possible to add a class onto the pulldowns, or actually done it?

Any help would be very much appreciated.

Thanks,

Wilko

That would be inside header template under <style></style> tags

SELECT {
	FONT-FAMILY: Verdana,Arial,Helvetica,sans-serif;
	FONT-SIZE: 11px;
	COLOR: #000000;
	BACKGROUND-COLOR: #CFCFCF
}
TEXTAREA, .bginput {
	FONT-SIZE: 12px;
	FONT-FAMILY: Verdana,Arial,Helvetica,sans-serif;
	COLOR: #000000;
	BACKGROUND-COLOR: #CFCFCF
}
