Re: WCAG 2.0 SC 1.4.4 - Text Zoom Vs Browser Zoom

I believe the current WCAG working group position is that each of the possible resizing options (page zoom, text size settings, or custom elements / styleswitchers) on its own would be sufficient to meet SC 1.4.4 Resize text if text can be magnified to 200%.

The Failure F69 (F69: Failure of Success Criterion 1.4.4 when resizing visually rendered text up to 200 percent causes the text, image or controls to be clipped, truncated or obscured / http://www.w3.org/TR/2014/NOTE-WCAG20-TECHS-20140408/F69 ) has been updated with a note to clarify that (this was necessary since the examples / screenshots included in F69 showed a text-only resizing scenario, inviting the interpretation that text-only resizing had to be supported).

Best, Detlev
