Day 47: ARIA Live Regions, Part 2

Yesterday during my Part 1 learning, I watched videos that gave me a great idea of how live regions worked. Today I looked over documentation to see what W3C had to say about it.

Things I accomplished

Read the WAI-ARIA documented parts on:

What I learned today

  • The politeness value of aria-live is just a strong suggestion to user agents and AT, but may be overridden by user agents, AT, or the user.
  • Some ARIA roles (i.e. log, status) already have default aria-live politeness levels (implicit value for role) when aria-live is not set.
  • aria-relevant indicates what notifications the user agent will trigger when the accessibility tree within a live region is modified.
  • aria-relevant values include:
    • additions
    • additions text
    • all
    • removals
    • text
  • aria-busy is a state, not a property.
  • aria-busy exists to indicate an element is being modified and that AT may want to wait until the modifications are complete before showing them to the user.
