Subject: Suppressing visibility of "invisible" frames?
No previous message | Next message →

Hello,

Some of our Web sites make use of frames that are supposed to be
invisible. These frames contain parameters that are relevant only to
systems, but provide nothing useful to human users. Screen readers don't
even pick up on the data within these frames, just the fact that the
frames themselves are there.

Is there a way to suppress visibility of frames that are supposed to be
invisible but aren't to JAWS/Window Eyes? E.g. is there an alt=""
equivalent for frames? I've done some preliminary research, but haven't
come up with anything.

Thanks in advance to anyone who can help,
Marguerite

You could try by hiding the content with CSS, since its accepted that
screen readers will not read content with display:none attached to it.
So either use display:none on the iframe or a containing div.

There is the title attribute which should describe the content or
function of each frame - http://webaim.org/techniques/frames/ However,
screen readers expect each frame to contain content, so if the title
is left off or is empty (title=""), the screen reader still identifies
the frame by using the frame name, document title, document file name,
or something else. So, there really isn't a good method of hiding the
frame from screen readers.

You should, however, give the frame a title such as title="empty
frame" or something similar so the user doesn't try to navigate
through it.

CSS (display:none or visibility:hidden) might work if applied to the
frame itself.

Another option is to move the frame functionality to an iframe.
