[Javascript] FORCING BROWSER TEXT SIZE and/or TEXT ZOOM SETTINGS

[Steven Pesant]

Hi there,

Curious to know if there is any way using Javascript or other language to 
force a TEXT SIZE (PC) or TEXT ZOOM (Mac) setting in a user's web browser?

In particular, I'd like to do the following:

	If user = PC and browser = IE
		set TEXT SIZE to SMALLEST

	else if user = PC and browser = NN
		set TEXT SIZE to 75%

	else if user = Mac and browser = IE
		set TEXT SIZE to 80%

	else if user = Mac and browser = NN
		set TEXT SIZE to 75%


NOTE: I'm already using style sheets throughout, but those settings get 
overridden by the end user's browser default font settings.

Thanks in advance.
