Re: Initial focus on search field?

Thanks, Deborah.

Yeah, that was my thought as well. I'm just not sure how
accommodating the team is going to be, what with the requirements
given to them by other stakeholders. I was hoping there might be some
creative accessibility workaround for this increasingly common
practice, or that screen reader users' expectations about things might
have changed as a result of how frequently this technique is used.

If I can't get them to budge on this, how bad would it be to provide a
hint to screen reader users that there was content before the search
field by using something an aria live region. A cookie could be set
so that the notification would only be provided the first time this
happened. Strikes me as a bad hack, but I'm trying to give them
options, if the preferred solution is not an option.

This is something I've wondered about generally: Are there instances
where it is best practice to provide invisible hints to screen reader
users about the way complex sites function or does the extra verbosity
of this and the possibility that such notices may not be updated as
pages change, pretty much always make this a bad idea?

Best,
Rob
