Lists

We often have brown bag lunchtime presentations at Clearleft. In the Before Times, this would involve a trip to Pret or Itsu to get a lunch order in, which we would then proceed to eat in front of whoever was giving the presentation. Often it’s someone from Clearleft demoing something or playing back a project, but whenever possible we’d rope in other people to swing by and share what they’re up to.

We’ve continued this tradition since making the switch to working remotely. Now the brown bag presentations happen over Zoom. This has two advantages. Firstly, if you don’t want the presenter watching you eat your lunch, you can switch your camera off. Secondly, because the presenter doesn’t have to be in Brighton, there’s no geographical limit on who could present.

Our most recent brown bag was truly excellent. I asked Léonie if she’d be up for it, and she very kindly agreed. As well as giving us a whirlwind tour of how assistive technology works on the web, she then invited us to observe her interacting with websites using a screen reader.

I’ve seen Léonie do this before and it’s always struck me as a very open and vulnerable thing to do. Think about it: the audience has more information than the presenter. We can see the website at the same time as we’re listening to Léonie and her screen reader.

We got to nominate which websites to visit. One of them—a client’s current site that we haven’t yet redesigned—was a textbook example of how important form controls are. There was a form where almost everything was hunky-dory: form fields, labels, it was all fine. But one of the inputs was a combo box. Instead of using a native select with a datalist, this was made with JavaScript. Because it was lacking the requisite ARIA additions to make it accessible, it was pretty much unusable to Léonie.

And that’s why you use the right HTML element wherever possible, kids!

The other site Léonie visited was Clearleft’s own. That was all fine. Léonie demonstrated how she’d form a mental model of a page by getting the screen reader to read out the headings. Interestingly, the nesting of headings on the Clearleft site is technically wrong—there’s a jump from an h1 to an h3—probably a result of the component-driven architecture where you don’t quite know where in the page a heading will appear. But this didn’t seem to be an issue. The fact that headings are being used at all was the more important fact. As Léonie said, there’s a lot of incorrect HTML out there so it’s no wonder that screen readers aren’t necessarily sticklers for nesting.

I’ve said it before and I’ll say it again: if you’re using headings, labelling form fields, and providing alternative text for images, you’re already doing a better job than most websites.

Headings weren’t the only way that Léonie got a feel for the page architecture. Landmark roles—like header and nav—really helped too. Inside the nav element, she also heard how many items there were. That’s because the navigation was marked up as a list: “List: six items.”

And that reminded me of the Webkit issue. On Webkit browsers like Safari, the list on the Clearleft site would not be announced as a list. That’s because the lists’s bullets have been removed using CSS.

Now this isn’t the only time that screen readers pay attention to styling. If you use display: none to hide an element from sight, it will also be unavailable to screen reader users. Makes sense. But removing the semantic meaning of lists based on CSS? That seems a bit much.

There are good reasons for it though. Here’s a thread from James Craig on where this decision came from (James, by the way, is an absolute unsung hero of accessibility). It turns out that developers went overboard with lists a while back and that’s why we can’t have nice things. In over-compensating from divitis, developers ended up creating listitis, marking up anything vaguely list-like as an unordered list with styling adjusted. That was very annoying for screen reader users trying to figure out what was actually a list.

And James also asks:

If a sighted user doesn’t need to know it’s a list, why would a screen reader user need to know or want to know? Stated another way, if the visible list markers (bullets, image markers, etc.) are deemed by the designers to be visually burdensome or redundant for sighted users, why burden screen reader users with those semantics?

That’s a fair point, but the thing is …bullets maketh not the list. There are many ways of styling something that is genuinely a list that doesn’t involve bullets or image markers. White space, borders, keylines—these can all indicate visually that something is a list of items.

If you look at, say, the tunes page on The Session, you can see that there are numerous lists—newest tunes, latest comments, etc. In this case, as a sighted visitor, you would be at an advantage over a screen reader user in that you can, at a glance, see that there’s a list of five items here, a list of ten items there.

So I’m not disagreeing with the thinking behind the Webkit decision, but I do think the heuristics probably aren’t going to be quite good enough to make the call on whether something is truly a list or not.

Still, while I used to be kind of upset about the Webkit behaviour, I’ve become more equanimous about it over time. There are two reasons for this.

Firstly, there’s something that Eric said:

We have come so far to agree that websites don’t need to look the same in every browser mostly due to bugs in their rendering engines or preferences of the user.

I think the same is true for screen readers and other assistive technology: Websites don’t need to sound the same in every screen reader.

That’s a really good point. If we agree that “pixel perfection” isn’t attainable—or desirable—in a fluid, user-centred medium like the web, why demand the aural equivalent?

The second reason why I’m not storming the barricades about this is something that James said:

Of course, heuristics are imperfect, so authors have the ability to explicitly override the heuristically determined role by adding role="list”.

That means more work for me as a developer, and that’s …absolutely fine. If I can take something that might be a problem for a user, and turn into something that’s a problem for me, I’ll choose to make it my problem every time.

I don’t have to petition Webkit to change their stance or update their heuristics. If I feel strongly that a list styled without bullets should still be announced as a list, I can specificy that in the markup.

It does feel very redundant to write ul role="list”. The whole point of having HTML elements with built-in semantics is that you don’t need to add any ARIA roles. But we did it for a while when new structural elements were introduced in HTML5—main role="main", nav role="navigation", etc. So I’m okay with a little bit of redundancy. I think the important thing is that you really stop and think about whether something should be announced as a list or not, regardless of styling. There isn’t a one-size-fits-all answer (hence why it’s nigh-on impossible to get the heuristics right). Each list needs to be marked up on a case-by-case basis.

And I wouldn’t advise spending too much time thinking about this either. There are other, more important areas to consider. Like I said, headings, forms, and images really matter. I’d prioritise those elements above thinking about lists. And it’s worth pointing out that Webkit doesn’t remove all semantic meaning from styled lists—it updates the role value from list to group. That seems sensible to me.

In the case of that page on The Session, I don’t think I’m guilty of listitis. Yes, there are seven lists on that page (two for navigation, five for content) but I’m reasonably confident that they all look like lists even without bullets or markers. So I’ve added role="list" to some ul elements.

As with so many things related to accessibility—and the web in general—this is a situation where the only answer I can confidentally come up with is …it depends.

Returning control

In his tap essay Fish, Robin sloan said:

On the internet today, reading something twice is an act of love.

I’ve found a few services recently that encourage me to return to things I’ve already read.

Findings is looking quite lovely since its recent redesign. They may have screwed up with their email notification anti-pattern but they were quick to own up to the problem. I’ve been taking the time to read back through quotations I’ve posted, which in turn leads me to revisit the original pieces that the quotations were taken from.

Take, for example, this quote from Dave Winer:

We need to break out of the model where all these systems are monolithic and standalone. There’s art in each individual system, but there’s a much greater art in the union of all the systems we create.

…which leads me back to the beautifully-worded piece he wrote on Medium.

At the other end of the scale, reading this quote led me to revisit Rob’s review of Not Of This Earth on NotComing.com:

Not of This Earth is an early example of a premise conceivably determined by the proverbial writer’s room dartboard. In this case, the first two darts landed on “space” and “vampire.” There was no need to throw a third.

Although I think perhaps my favourite movie-related quotation comes from Gavin Rothery’s review of Saturn 3:

You could look at this film superficially and see it as a robot gone mental chasing Farrah Fawcett around a moonbase trying to get it on with her and killing everybody that gets in its way. Or, you could see through that into brilliance of this film and see that is in fact a story about a robot gone mental chasing Farrah Fawcett around a moonbase trying to get it on with her and killing everybody that gets in its way.

The other service that is encouraging me to revisit articles that I’ve previously read is Readlists. I’ve been using it to gather together pieces of writing that I’ve previously linked to about the Internet of Things, the infrastructure of the internet, digital preservation, or simply sci-fi short stories.

Frank mentioned Readlists when he wrote about The Anthologists:

Anthologies have the potential to finally make good on the purpose of all our automated archiving and collecting: that we would actually go back to the library, look at the stuff again, and, holy moses, do something with it. A collection that isn’t revisited might as well be a garbage heap.

I really like the fact that while Readlists is very much a tool that relies on the network, the collected content no longer requires a network connection: you can send a group of articles to your Kindle, or download them as one epub file.

I love tools like this—user style sheets, greasemonkey scripts, Readability, Instapaper, bookmarklets of all kinds—that allow the end user to exercise control over the content they want to revisit. Or, as Frank puts it:

…users gain new ways to select, sequence, recontextualize, and publish the content they consume.

I think the first technology that really brought this notion to the fore was RSS. The idea that the reader could choose not only to read your content at a later time, but also to read it in a different place—their RSS reader rather than your website—seemed quite radical. It was a bitter pill for the old guard to swallow, but once publishing RSS feeds became the norm, even the stodgiest of old media producers learned to let go of the illusion of control.

That’s why I was very surprised when Aral pushed back against RSS. I understand his reasoning for not providing a full RSS feed:

every RSS reader I tested it in displayed the articles differently — completely destroying my line widths, pull quotes, image captions, footers, and the layout of the high‐DPI images I was using.

…but that kind of illusory control just seems antithetical to the way the web works.

The heart of the issue, I think, is when Aral talks about:

the author’s moral rights over the form and presentation of their work.

I understand his point, but I also value the reader’s ideas about the form and presentation of the work they are going to be reading. The attempt to constrain and restrict the reader’s recontextualising reminds me of emails I used to read on Steve Champeon’s Webdesign-L mailing list back in the 90s that would begin:

How can I force the user to …?

or

How do I stop the user from …?

The questions usually involved attempts to stop users “getting at” images or viewing the markup source. Again, I understand where those views come from, but they just don’t fit comfortably with the sprit of the web.

And, of course, the truth was always that once something was out there on the web, users could always find a way to read it, alter it, store it, or revisit it. For Aral’s site, for example, although he refuses to provide a full RSS feed, all I have to is use Reeder with its built-in Readability functionality to get the full content.

Breaking Things

This is an important point: attempting to exert too much control will be interpreted as damage and routed around. That’s exactly why RSS exists. That’s why Readability and Instapaper exist. That’s why Findings and Readlists exist. Heck, it’s why Huffduffer exists.

To paraphrase Princess Leia, the more you tighten your grip, the more content will slip through your fingers. Rather than trying to battle against the tide, go with the flow and embrace the reality of what Cameron Koczon calls Orbital Content and what Sara Wachter-Boettcher calls Future-Ready Content.

Both of those articles were published on A List Apart. But feel free to put them into a Readlist, or quote your favourite bits on Findings. And then, later, maybe you’ll return to them. Maybe you’ll read them twice. Maybe you’ll love them.
