Dear all,
I have a problem with a tab bar . If I arrow into it using NVDA/Firefox the=
three tabs are read as a single element. It seems to be related to a class=
=3D"react-tabs__tab" on the <li role=3D"tab"> because the addition of that =
class seems to cause Firefox to remove one of the listitem's children from =
the accessibility tree. In a tab bar without this class, each tab node has =
two children - a statictext bullet and a text leaf containing the text of t=
he list item. NVDA reads each tab as a separate element. But the addition =
of class=3D"react-tabs__tab" to the <li role=3D"listitem"> seems to cause F=
irefox to remove the bullet from the tree and NVDA concatenates all tabs in=
to one element. The class definition is:
:global(.react-tabs__tab) {
position: relative;
display: inline-block; /* Include border-bottom width */
padding: var(--space16) var(--space24) calc(var(--space16) - 5px) var(--s=
pace24);
font-size: var(--font18);
font-weight: 700;
color: var(--lightNeutralColor);
text-transform: uppercase;
letter-spacing: 0.5px;
list-style: none;
cursor: pointer;
outline: 1px solid transparent;
}
Disabling list-style or display has no effect.
I've looked at this in Chrome and I see that it removes the bullet child fr=
om a listitem in the accessibility tree when you add the tab role to the <l=
i>s, but NVDA still reads the tabs as separate elements, so it doesn't seem=
to be just the existence of that bullet.
At this point I'm a bit stumped. Can anyone suggest a possible solution or =
further avenue for investigation?
If you want to see the full source, you can access Skillsoft's whole eLearn=
ing library for free for 60 days during Covid-19. Go to skillsoft.com, foll=
ow the Free Access link, fill in your name, email, and company name and sel=
ect Get Access. You'll get an email with a link for setting a password and =
logging in. Once you are in, and have got past the short onboarding where y=
ou get to select your areas of interest, tab to any course on the home page=
and launch it. Arrow down to the tab bar containing Content, Overview and =
Resources tabs and see what happens.
I appreciate any help anyone can give me on this.

display: inline-block
The following example is read the same way, all elements are read at the
same time when using the down arrow with NVDA.
<style>
li {display:inline-block;}
</style>
<ul>
<li>alpha</li>
<li>beta</li>
<li>gamma</li>
</ul>
I get similar behavior with other elements when using the down arrow with
NVDA. Several elements are read at the same time. I guess this is
expected behavior. I've heard it before but just ignored it. I knew there
was a reason but didn't have enough incentive to look it up.
<button>alpha</button>
<br>
<button>beta</button>
<button>gamma</button>
<br>
The alpha button is read by itself but the beta and gamma buttons are read
as one line when using the down arrow. The buttons are essentially inline,
just like the list items when using inline-block.
I don't think it's a problem in your scenario. I can tab (key) to the tab
widget and use the left/right arrow keys with NVDA running and it switches
tabs. The fact that it reads all the tabs as one line when using the down
arrow is ok.

This is called screen layout mode and can be adjusted in the Browse mode settings. JAWS also has a setting that is more likely to keep multiple object on the same line as a single phrase, though the default between NVDA and Jaws are different.

So I guess what you're all saying is, this is the way NVDA works with this CSS and users can cope with it and get around it? It seems avoidable though and I do think it would be preferable if this didn't happen. I'll talk to my devs and see if they can use alternative CSS.
Thanks guys.

I wouldn't worry about it. NVDA has the same behaviour for all horizontal lists, so people who use NVDA will encounter it with the main menu on pretty much very website they visit. They may even consider it strange if your menu does not behave this way.
WCAG does not say anything about how screen readers should behave, so it's not going to be a WCAG non-conformance. We all have opinions, but user testing is the only way to know if it's really a problem that needs to be fixed.

So I guess what you're all saying is, this is the way NVDA works with this CSS and users can cope with it and get around it? It seems avoidable though and I do think it would be preferable if this didn't happen. I'll talk to my devs and see if they can use alternative CSS.
Thanks guys.

Thanks for this, as I was going to outline the same. Each screen reader has slight differences in this space on the different platforms.

[External Email] This email was sent from outside the organisation â be cautious, particularly with links and attachments.
This is called screen layout mode and can be adjusted in the Browse mode settings. JAWS also has a setting that is more likely to keep multiple object on the same line as a single phrase, though the default between NVDA and Jaws are different.

Thanks, Jonathan. I couldn't remember the exact term that NVDA used.
"Screen layout" mode. I can toggle that with NVDA+v and can hear the
difference when arrowing up/down and hear each list item separately.
But I agree with others that nothing needs to be done to "fix" the page.

If you don't want to listen to us about if this is how NVDA users expect your layout, then please join the nvda group at groups.io <http://groups.io/>; and ask them to review the patterns you are looking into and if they feel they understand what you are attempting to do.
There are over 1300 NVDA users on that list some of whom are quite vocal.
