Understanding SC 1.4.4 Resize Text
Except for captions and images of text, text can be resized without assistive technology up to 200 percent without loss of content or functionality. (Level AA).
This success criterion requires that the text – both static and that are part of user interface components that are visible to the users must be resizable (scalable) to 200% without the help of any assistive technologies like screen magnifiers. Even though the user agents like the browsers that meet UAG (User Agent Guidelines) 1.0 bear the responsibility of scaling or zooming the text up to 200%, it is the authors responsible for providing that support to the browsers.
What do I do as the content author?
The authors or developers have to ensure:
Users with low vision or limited vision who consume the content without any assistive technology but use browsers’ zoom functionality alone.
Great post. I have a query: The Success Criteria says that “text can be resized without assistive technology up to 200 percent without loss of content or functionality.”. I noticed that while using Chrome if we use the Zoom In and Zoom Out control (by clicking on More Options on Chrome or by using CTRL and +/-, the whole page is magnified. It doesn’t only magnifies the text but rather all the content.
When using Firefox or Safari browser, they have option for “Zoom text only” but this option is not available in Chrome browser (there is an extension called “Zoom Text Only” which achieves the same functionality as Firefox and Safari browser natively has).
My query is: does the success criteria says that only text should zoom to 200% or all the content should zoom to 200%?
