Accessibility Support
No accessibility support issues known.
Assumptions
- svg elements with a semantic role of graphics-document and with an empty ("") accessible name are ignored by assistive technologies tested for this rule. If some assistive technology does not ignore these elements, and that assistive technology is required for conformance, passing this rule does not ensure all decorative svg elements can be ignored, and the Success Criterion 1.1.1 Non-Text Content may still not be satisfied. The same is true for canvas elements with no semantic role and an empty ("").
- A web page with informative images without an accessible name may conform to WCAG 2.1 Level A when the information provided by that image is available elsewhere on the web page itself. For example if an equivalent text is adjacent to the image, or if the text alternative is included in the accessible name of a parent element.
