Plain Language Recommendations
Non-text content that is
- a control or accepts user input;
- time-based media; and/or
- non-text content that is intended to create a specific sensory experience
must have a text alternative that provides descriptive identification (so that the user at least knows what the non-text content is and why it is there).
Example
- For an image that is used as a submit button, include link text as well as image OR use alt tag.
Notes
- Text alternatives (i.e., transcripts) are dealt with in a different guideline.
- Specific sensory experience e.g., performance of a flute solo.
