Re: Voiceover detection in JavaScript

"I have a scrollable div. I have programmed it to be fully keyboard
accessible."

I'm interested to know what needed "programming" there, why wasn't it
accessible to start with?

With a simple test case, a scrollable div itself is fine with VoiceOver:
http://alastairc.ac/testing/scrollable-div.html

It does not scroll itself visibly, but VoiceOver reads all the content.


"The only place it is not accessible is on iOS because of Voiceover, since

I'm not convinced that is the case, there must be something else going on.
Have you got a URL you can share?

No. What you are hearing is that *if* coded to (HTML) standards and (WCAG)
guidelines, it would be better for VoiceOver to fix an issue than the
developer. [1]

However, I doubt that is the case.
