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 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.
