Text detectable
Normative Text
All visible text has a programmatically determinable equivalent.
Except when
- making visible text programmatically determinable would lead to duplication within the view.
Tests
This section is non-normative.
Procedure
For all visible text:
2. If the text is embedded in an image, check that the text has a text alternative or can be accurately read using the accessibility support set.
3. If text content, check that the text is not hidden using code such as the aria-hidden attribute.
Expected results
- #2 and #3 are true.
Tests
This content needs to be written.
Key Terms
- accessibility support set
group of user agents and assistive technologies you test with
The AGWG is considering defining a default set of user agents and assistive technologies that they use when validating guidelines.
Accessibility support sets may vary based on language, region, or situation.
If you are not using the default accessibility set, the conformance report should indicate what set is being used.
- accessibility supported
available and working in the user agents and assistive technology in the accessibility support set
The working group intended to include a default accessibility support set. See Default accessibility support set #277.
- ASCII art
picture created by a spatial arrangement of characters or glyphs (typically from the 95 printable characters defined by ASCII)
- human language
language that is spoken, written, or signed (through visual or tactile means) to communicate with humans
See also sign language.
- non-text content
any content that is not a sequence of characters that can be programmatically determinable or where the sequence is not expressing something in human language
This includes ASCII art (which is a pattern of characters), emoticons, leetspeak (which uses character substitution), and images representing text
- programmatically determinable
meaning of the content and all its important attributes can be determined by software functionality that is accessibility supported
- sign language
a language using combinations of movements of the hands and arms, facial expressions, or body positions to convey meaning
- text
sequence of characters that can be programmatically determined, where the sequence is expressing something in human language
- text alternative
text that is programmatically associated with non-text content or referred to from text that is programmatically associated with non-text content
