Hi Gregg,
 
yea, many thanks for quick reply. .. thats part of the info I need. 
 
Advantage for Zoom is that it does enlarge images proportionally also. Our designs need that. It needs to be tested if reflowing of text will become an issue.
 
Questions now: 
 
a) is Greggs Level AA rating when using zoom correct? Is that sufficient success criteria for W3C regarding font scaling?
b) will the sections that reccommend to use em units be modified to reflect new zooming techniques in browsers?
b) is horizontal scrolling when using zoom a no-go for accessibility or is it more a usability issue and a consequecne of AA classification? 
 
Regards,
Stefan

	Hi Aaron, 

	 

	      Browsers that have ZOOM on them make the Level AA provisions easy to conform to.  

	 The Level AAA provisions require reflowing the text so that horizontal scrolling isn't necessary so Zoom won't help you there.   The "enlarge text font" in browsers would allow users to increase font size but the content needs to be written properly for this to work.   

	 

	Does that help?

		Michael, 

		I would like to know if the presence of new step-less zooming abilities (e.g. PageZoom in IE7) will make some of the W3C requirements for font scaling (like using relative instead of absolute units on web pages) become obsolete.

		If not, if any complaints, please explain or point me to some location where I can find arguments against built-in zooming techniques in browsers.

		We need your input here to give our html-based technologies a definitive answer if they must use relative units or if they can rely on IE7 for font scaling.

		Aaron, 

		I would like to know if something comparable to PageZoom in IE7 is planned for FireFox 3. 

		 

		Best Regards, 
		Stefan
