Supported 11.2.1.11 Audio control ICT is non-web software that provides a user interface, it shall satisfy the Success Criterion in Table 11.11: Audio control: If any audio in a software plays automatically for more than 3 seconds, either a mechanism is available to pause or stop the audio, or a mechanism is available to control audio volume independently from the overall system volume level. Supported 11.2.1.12 Contrast (minimum) Where ICT is non-web software that provides a user interface, it shall satisfy the Success Criterion in Table 11.12: Contrast (minimum): The visual presentation of text and images of text has a contrast ratio of at least 4.5:1, except for the following: Large Text: Large-scale text and images of large-scale text have a contrast ratio of at least 3:1. Incidental: Text or images of text that are part of an inactive user interface component, that are pure decoration, that are not visible to anyone, or that are part of a picture that contains significant visual content, have no contrast requirement. Logotypes: Text that is part of a logo or brand name has no minimum contrast requirement. Supported With Exceptions In the Edge browser, there are a few places where the contrast ratio is lower than 4.5:1 for some text, including the link text on the InPrivate page when using dark theme, and “Should I trust this site?” links in light and dark theme. 11.2.1.13 Resize text Where ICT is non-web software that provides a user interface and that supports access to enlargement features of platform or assistive technology, it shall satisfy the Success Criterion in Table 11.13: 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.

Supported 11.3.2.8 Label relationships Where the software provides a user interface it shall expose the relationship that a user interface element has as a label for another element, or of being labelled by another element, using the services as described in clause 11.3.2.3, so that this information is programmatically determinable by assistive technologies. Supported 11.3.2.9 Parent-child relationships Where the software provides a user interface it shall, by using the services as described in clause 11.3.2.3, make the relationship between a user interface element and any parent or children elements programmatically determinable by assistive technologies. Supported 11.3.2.10 Text the software provides a user interface it shall, by using the services as described in clause 11.3.2.3, make the text contents, text attributes, and the boundary of text rendered to the screen programmatically determinable by assistive technologies.
