• 1.1.1 Non-text content
  • Situation A: If a short description *can* serve the same purpose and present the same information as the non-text content
    • Using aria-labeledby (note: on img, you must also use @alt to be valid HTML 5 as of last call draft) [James Nurthen]
    • Using aria-label (note: on img, you must also use @alt to be valid HTML 5 as of last call draft) [James Nurthen]
    • using title [James Nurthen]
  • Situation B: If a short description *can not* serve the same purpose and present the same information as the non-text content (e.g., a chart or diagram):
    • Using aria-describedby [David MacDonald]
  • Situation C: If non-text content is a control or accepts user input:
    • Using aria-label [David MacDonald]
    • Using aria-labeledby [David MacDonald]
  • Situation D: If non-text content is time-based media (including live video-only and live audio-only); a test or exercise that would be invalid if presented in text; or primarily intended to create a specific sensory experience
  • Situation F: If the non-text content should be ignored by assistive technology:
    • Using role=presentation along with H67 (note that this is still being discussed by the WG)
  • Short text alternative techniques for use in sufficient techniques above
    • (not in the LC decision but still being discussed by the WG: aria-labeledby and aria-label)

  • Using ARIA landmarks [David MacDonald]
  • Situation A:
    • Using aria-label, aria-labledby, and aria-describedby to provide labels and descriptions [David MacDonald - see above]
