Hi all,

We have a weird issue where the text on some links is available to
screenreaders but not visible using a keyboard. So when a keyboard
user tabs to the link, they only get to see a tiny focus rectangle.

Where (if at all) does this one fail WCAG2? Feels like it should be an
info and relationships or a labels issue, but I can'tfind a specific
criterion to fail it under.

Thanks as always, Lyn

I would mark the following as failures for a AA audit. 1.4.3 Contrast minimum. The invisible text obviously does not have sufficient contrast to be read by anyone. Also, 2.1.1 Keyboard. You cannot operate something via the keyboard if you do not know what it does.

These types of statements always cause me concern. If you can't find a
WCAG failure would it not be documented as an issue? It's clearly an
accessibility and usability issue and should be noted as such even if
it isn't a WCAG failure.

Remember that WCAG only deals with accessibility for users with
disabilities - if something's inaccessible to nearly everyone (as is
the case with invisible link text), then it's not a WCAG failure. This
is why things like white text on a white background (at Level A), 1
pixel sized text, entirely ambiguous link text (such as "here"), etc.
are not WCAG failures, even though they are all significant
accessibility and usability issues.

Hi Jared,

Thanks for your comments.

This is only a failure for keyboard users. the links are invisible to
mouse users because they're replaced by another mechanism. I suspect
the developers have made these available specifically for screenreader
users, but they're likely to cause difficulty for sighted keyboard
users because it's the only mechanism for them too.

I don't have any statistics around how many people use a keyboard to
mitigate for a disability. If there aren't many, then I guess this
turns into a usability issue.

KR, Lynn

Hi Michael,

Thanks for those useful suggestions.

I can't really fail it on contrast, because it's been resized to 1px
to make it invisible so there's no contrast to test.

But yes, I should be able to fail it under keyboard operable.

Cheers, Lynn

No, if there were not many keyboard users, that actually wouldn't turn
this accessibility issue into a usability issue. It is still an
accessibility issue for all of those speech recognition and keyboard
users (much speech recognition navigation comes from emulating the
keyboard).

Now the fact is, there actually are a large number (not that I have any
of the statistics at my fingertips). But there's no caveat in WCAG saying
that if there are only a small number of people with a disability, their
accessibility needs don't exist. If you want to create an accessible
site, you have to accommodate users with accessibility needs, without
trying to anticipate how many of those users exist. If your site isn't
accessible to keyboard users, you will think there are no
keyboard-only/speech recognition users in the world, because none of
us will come to your site.

Indeed (also relating to the other thread about tiny clickable
elements). In my reports, I often include an issue, explain that
*nominally* a tested page/site passes the letter of WCAG, but that
nonetheless there are things that should be fixed (same goes for, say,
still including a skip link, despite the use of landmark roles and
proper heading structure, to account for keyboard users without any
special AT).

Zero contrast sounds like there is insufficient contrast to me…

The requirement is that users can determine that it is there. I don't think there is anything in WCAG that makes it clear, but "sufficient contrast to be perceivable" generally requires being a certain size as well as colour combination.

Has anyone here filed a bug on WCAG or its associated documents for this issue? I think that would be a useful thing to do - so if the answer is no, I'll do it.
