My point is that we need the support before we finish making recommended techniques. We need some pioneer author/web developers to work with pioneer browser and platform engoineers to get this right and understand the limitation and restrictions in order to make general recommendations that could become mandated. ____________________________________________ Regards, Phill Jenkins, IBM Accessibility From: Jonathan Avila <jon.avila@ssbbartgroup.com> To: Phill Jenkins/Austin/IBM@IBMUS, "w3c-wai-ig@w3.org" <w3c-wai-ig@w3.org> Date: 01/19/2016 09:25 AM Subject: RE: Allowing font size changes [Phil wrote] I agree it is a user agent responsibility *and* an end user responsibility to know how to set the setting or have an assistant set it for them. It is a lot easier and more efficient to set it once per browser and/or per OS platform that to try to find the yet another unique way an individual website / developer did it. Using the excuse that some browser or platforms are hard to set & use does not justify leaving it up to millions of web developers to try to figure it out. We seem to agree on the following: Ø Pinch zoom and text resize without horizontal scroll are different Ø Pinch zoom meets current WCAG conformance requirements if text resizes up to 200% without loss of functionality Ø WCAG conformance can be met by providing text resize controls that enlarge all text up to 200% without loss of functionality (not generally recommend approach but sufficient) Ø Text resize may be preferable for many users Ø User agents and platforms should provide a method to enlarge text content The challenge is that it may be difficult for authors to respond to a wide range of text size changes without creating horizontal scrolling. Yes, responsive sites can be used but these may be based on breakpoints that may not exist smaller than the width of a mobile device. If the user wants to resize text on a mobile device the author would need to plan for that even if the site is responsive. What many sites do is keep the UI static but allow for text resize of the main content area ? yes, this is similar to the ?reader? mode some user agents and platforms offer. My point though is that responding to larger text settings in the OS does require work by the author just as adding controls to resize text requires work by the author. Simply offering the settings in the user agent and exposing them to the page does not guarantee they will automagically make the page content work correctly. In addition, pinch zoom on a mobile device can be broken surprisingly easily. For example, by use a floating fixed position bar at the top of the page. When the page is zoomed the bar takes up most of the display leaving no room to view the page contents. So authors need some flexibility in how they meet the SC.

I believe it is more useful and less confusing when the audience of the web app is known or controlled and has had some training or orientation, such as employees of a company with a particular app, or when the app is being designed specifically for a group of users who have the same or know disability, such as a rehabilitation app. The advocacy effort here needs to be directed at OS platform and browser developers and AT developers, not web developers. We are starting to get good traction with the iOS and Andorid app developers not that so many accessibility features are now included in the platform. Why can't we (meaning the web accessibility community) focus on the handful of platform and browser developers and stop wasting our time and the millions of web developers time on this topic? ____________________________________________ Regards, Phill Jenkins, From: "Chaals McCathie Nevile" <chaals@yandex-team.ru> To: w3c-wai-ig@w3.org Date: 01/18/2016 02:00 PM Subject: Re: Allowing font size changes On Fri, 15 Jan 2016 15:46:19 +0100, Patrick H.

The OS and browser are each broken if they don't provide a way to increase font size, and zoom - yes they are different. And both have important uses. I'm not sure there is any absolute requirement that authors add a redundant shortcut to do the same, but in practice it can be a useful thing for many users, especially given that in practice many OS and browser soutions are hard to find or use.
