Re: Rollover Text with Images - ARIA popup or not?

Bryan, I think the aria-haspopup attribute could be useful in situations
such as this. Is it a hard requirement that it can only be used in menus?
It seems like it could be useful to indicate when a dialog might appear as
well as when rollovers appear.

Judith, the aria-haspopup would provide indication to ARIA supported AT
that something opens -- a fallback could be to add the text you describe
for non-ARIA supported technology and other users.

If the content is activated by the user you'll want to move focus to the
new content with the JavaScript focus() method and make sure that the
revealed element can receive focus -- for example by setting
tabindex="-1". If other content can't be rolled over until this item is
closed you'll need a way to close the pop-up too.

Best Regards,

Jonathan

Is the popup a menu? One thing to keep in mind is that aria-haspopup
should only be used on menus.

Subject: [WebAIM] Rollover Text with Images - ARIA popup or not?

I am advising an interaction design team on how to make a new component
accessible.

On a related, but slightly different component - balloon help (aka bubble
help), we are using ARIA (aria-haspopup="true") and indicating the
beginning and end of the popup with hidden text.

This new component is not an actual popup. It pairs rollover text with a
changing image - on hover, click, key press enter, and tap on the link.

Accessibility requirements:

* The image will include meaningful alt text
* Hidden text after the trigger link reads "displays image"

Would this type of interaction be perceived as a popup to someone who
cannot see the screen?

Logically I don't think so, but wanted to see what others would advise. Is
hidden text "displays image" sufficient to provide the intended perception
and consumption of the information?


Thanks,
